Genitourinary Cancer

Men with advanced prostate cancer undergoing local therapies such as radiation therapy or radical prostatectomy experience significantly more gastrointestinal and sexual issues, along with problems with incontinence, in the following years, than systemically treated patients. These were the findings of a retrospective cohort study in JAMA Network Open.

The standard treatment of advanced prostate cancer is androgen deprivation therapy (ADT). “The role of local therapy has been debated for several years. Studies have shown that radiation therapy or radical prostatectomy can improve patient survival under certain conditions,” said Hubert Kübler, MD, director of the Clinic and Polyclinic for Urology and Pediatric Urology at the University Hospital Würzburg in Germany. “At academic centers, a local therapy is pursued for oligometastatic patients if they are fit enough.”

The hope is to spare patients the side effects of ADT over an extended period and thus improve their quality of life. “But what impact does local therapy itself have on the men’s quality of life, especially considering that the survival advantage gained may be relatively small?” wrote study author Saira Khan, PhD, MPH, assistant professor of surgery at Washington University School of Medicine in St. Louis, Missouri, and her colleagues.

Examining Side Effects

This question has not been thoroughly examined yet. “To our knowledge, this is one of the first studies investigating the side effects of local therapy in men with advanced prostate cancer for up to 5 years after treatment,” wrote the authors.

The cohort study included 5500 US veterans who were diagnosed with advanced prostate cancer between January 1999 and December 2013. The tumors were in stage T4 (tumor is fixed or has spread to adjacent structures), with regional lymph node metastases (N1), and partially detectable distant metastases (M1).

The average age was 68.7 years, and 31% received local therapy (eg, radiation therapy, radical prostatectomy, or both), and 69% received systemic therapy (eg, hormone therapy, chemotherapy, or both).

Types of Local Therapy

Combining radiation therapy and radical prostatectomy “diminishes the meaningfulness of the study results,” according to Dr. Kübler. “The issue should have been analyzed in much finer detail. Studies clearly show, for example, that radiation therapy consistently performs slightly worse than prostatectomy in terms of gastrointestinal complaints.”

In their paper, the researchers reported that the prevalence of side effects was high, regardless of the therapy. Overall, 916 men (75.2%) with initial local therapy and 897 men (67.1%) with initial systemic therapy reported experiencing at least one side effect lasting more than 2 years and up to 5 years.

In the first year after the initial therapy, men who underwent local therapy, compared with those who underwent systemic therapy, experienced more of the following symptoms:

• Gastrointestinal issues (odds ratio [OR], 4.08)
• Pain (OR, 1.57)
• Sexual dysfunction (OR, 2.96)
• Urinary problems, predominantly incontinence (OR, 2.25)

Lasting Side Effects

Even up to year 5 after the initial therapy, men with local therapy reported more gastrointestinal and sexual issues, as well as more frequent incontinence, than those with systemic therapy. Only the frequency of pain equalized between the two groups in the second year.

“Our results are consistent with the known side effect profile [of local therapy] in patients with clinically localized prostate cancer receiving surgery or radiation therapy instead of active surveillance,” wrote the authors.

The comparison in advanced prostate cancer, however, is not with active surveillance but with ADT. “As the study confirmed, ADT is associated with various side effects,” said Dr. Kübler. Nevertheless, it was associated with fewer side effects than local therapy in this study. The concept behind local therapy (improving prognosis while avoiding local problems) is challenging to reconcile with these results.

Contradictory Data

The results also contradict findings from other studies. Dr. Kübler pointed to the recently presented PEACE-1 study, where “local complications and issues were reduced through local therapy in high-volume and high-risk patients.”

The study did not consider subsequent interventions, such as how many patients needed transurethral manipulation in the later course of the disease to address local problems. “There are older data showing that a radical prostatectomy can reduce the need for further resections,” Dr. Kübler added.

“I find it difficult to reconcile these data with other data and with my personal experience,” said Dr. Kübler. However, he agreed with the study authors’ conclusion, emphasizing the importance of informing patients about expected side effects of local therapy in the context of potentially marginal improvements in survival.

Different Situation in Germany

“As practitioners, we sometimes underestimate the side effects we subject our patients to. We need to talk to our patients about the prognosis improvement that comes with side effects,” said Dr. Kübler. He added that a similar study in Germany might yield different results. “Dr. Khan and her colleagues examined a very specific patient population: Namely, veterans. This patient clientele often faces many social difficulties, and the treatment structure in US veterans’ care differs significantly from ours.”

Lowering the recommended age for baseline prostate-specific antigen (PSA) would reduce prostate cancer deaths by about 30% in Black men without significantly increasing the rate of overdiagnosis, according to new screening guidelines from the Prostate Cancer Foundation.

Specifically, baseline PSA testing in Black men should begin at age 40-45, sooner than current guidelines recommend, and should be followed by regular screening intervals, preferably annually, at least until age 70, a multidisciplinary panel of experts and patient advocates determined based on a comprehensive literature review.

The panel’s findings were presented in a poster at the ASCO Genitourinary Symposium.

“Black men in the United States are considered a high-risk population for being diagnosed with and dying from prostate cancer,” lead author Isla Garraway, MD, PhD, of the University of California, Los Angeles, and colleagues wrote. Specifically, Black men are about two times more likely to be diagnosed with and die from prostate cancer than White men. But, the authors continued, “few guidelines have outlined specific recommendations for PSA-based prostate cancer screening among Black men.”

The US Preventive Services Taskforce recommendations, which are currently being updated, set the PSA screening start age at 55. The task force recommendations, which dictate insurance coverage in the United States, acknowledged “a potential mortality benefit for African American men when beginning screening before age 55 years” but did not explicitly recommend screening earlier.

Current guidelines from the American Cancer Society call for discussions about screening in average-risk men to begin at age 50-55. The recommendations do specify lowering the age to 45 for those at a high risk for prostate cancer, which includes Black men as well as those with a first-degree relative diagnosed with prostate cancer before age 65. In some cases, screening can begin at age 40 in the highest risk men — those with more than one first-degree relative who had prostate cancer at a young age.

The Prostate Cancer Foundation “wanted to address the confusion around different guideline statements and the lack of clarity around screening recommendations for Black men,” said William K. Oh, MD, of The Tisch Cancer Institute, Icahn School of Medicine at Mount Sinai, New York City, who chaired the panel for the new guidelines. “We thus convened a distinguished panel of experts from diverse backgrounds and expertise to create six guidelines statements to help Black men, their families, and their healthcare providers to consider options for prostate cancer screening based on the best available evidence.”

After reviewing 287, the expert panel developed six new guideline statements, reaching at least 80% consensus among panel members, addressing screening for Black men:

Because Black men are at a high risk for prostate cancer, the benefits of screening generally outweigh the risks.

PSA testing should be considered first line for prostate cancer screening, although some providers may recommend an optional digital rectal exam in addition to the PSA test.

Black men should engage in shared decision-making with their healthcare providers and other trusted sources of information to learn about the pros and cons of screening.

For Black men who elect screening, a baseline PSA test should be done between ages 40 and 45, and annual PSA screening should be strongly considered based on the PSA value and the individual’s health status.

Black men over age 70 who have been undergoing prostate cancer screening should talk with their healthcare provider about whether to continue PSA testing and make an informed decision based on their age, life expectancy, health status, family history, and prior PSA levels.

Black men who are at even higher risk due to a strong family history and/or known carriers of high-risk genetic variants should consider initiating annual PSA screening as early as age 40.

These statements are based on “the best available evidence, which overwhelmingly supports the conclusion that Black men in the US could benefit from a risk-adapted PSA screening,” the investigators concluded, noting that the latest evidence “warrants revisiting current recommendations for early [prostate cancer] detection in Black men from other national guideline groups.”

“We believe that the outcome of these more directed guidelines will be to give clarity to these men,” Dr. Oh added.

The Stockholm3 (A3P Biomedical) multiparametic blood test has shown accuracy in assessing the risk of prostate cancer, exceeding that of the standard prostate-specific antigen (PSA)-based test, in Swedish patients. That improved accuracy was observed across diverse racial and ethnic groups, in a new study.

“The Stockholm3 outperformed the PSA test overall and in every subcohort, with an impressive reduction of unnecessary biopsies of 40% to 50%, while maintaining relative sensitivity,” first author Scott E. Eggener, MD, said in presenting the findings at the ASCO Genitourinary Cancers Symposium. The test “has attractive characteristics in a diverse cohort, including within various racial and ethnic subgroups,” added Dr. Eggener, professor of surgery and radiology at the University of Chicago.

While the PSA test, the standard-of-care in prostate cancer risk assessment, reduces mortality, the test is known to have a risk for false positive results, leading to unnecessary prostate biopsies, as well as overdiagnosis of low-risk prostate cancers, Dr. Eggener explained in his talk.

Randomized trials do show “fewer men die from prostate cancer with screening [with PSA testing], however, the likelihood of unnecessarily finding out about a cancer, undergoing treatment, and exposure to potential treatment-related side effects is significantly higher,” Dr. Eggener said in a interview.

The Stockholm3 clinical diagnostic prostate cancer test, which has been used in Sweden and Norway since 2017, was validated in a sample of nearly 60,000 men in the STHLM3 study (doi: 10.1016/S1470-2045[15]00361-7), which was published in The Lancet Oncology in December 2015. That study showed significant improvement over PSA alone detection of prostate cancers with a Gleason score of at least 7 (P < .0001), Dr. Eggener explained.

The test combines five plasma protein markers, including total and free PSA, PSP94, GDF-15 and KLK2, along with 101 genetic markers and clinical patient data, including age, previous biopsy results and family history.

Because the Stockholm3 test was validated in a Swedish population cohort, evidence on the accuracy of the test in other racial and ethnic populations is lacking, the authors noted in the abstract.

Study Methods and Results

To further investigate, Dr. Eggener and his colleagues conducted the prospective SEPTA trial, involving 2,129 men with no known prostate cancer but clinical indications for prostate biopsy, who were referred for prostate biopsy at 17 North American sites between 2019 and 2023.

Among the men, 24% were self-identified as African American/Black; 46% were White/Caucasian; 14% were Hispanic/Latina; and 16% were Asian. The men’s median age was 63; their median PSA value was 6.1 ng/mL, according to the abstract.

Of the patients, 16% received magnetic resonance imaging (MRI)-targeted biopsies and 20% had prior benign biopsies, the abstract notes.

Biopsy results showed that clinically significant prostate cancer, defined as International Society of Urological Pathology (ISUP) Gleason Grade group ≥ 2, was detected in 29% of patients, with 14% having ISUP 1 cancer and 57% of cases having been benign, according to the abstract.

Overall detection rates of grade 2 or higher were 37% for African American/Black, 28% for White/Caucasian, 29% for Hispanic/Latino, and 21% Asian.

In terms of sensitivity of the two tests, the Stockholm3 (cut-point of ≥ 15) was noninferior compared with the traditional PSA cut-point of ≥ 4 ng/mL (relative sensitivity 0.95).

Results were consistent across ethnic subgroups: noninferior sensitivity (0.91-0.98) and superior specificity (2.51-4.70), the abstract authors reported.

Compared with the use of the PSA test’s cut-point of ≥ 4 ng/mL, the use of Stockholm3’s cut-point of ≥ 15 or higher would have reduced unnecessary biopsies by 45% overall, including by 46% among Asian and Black/African American patients, by 53% in Hispanic patients and 42% in White patients, according to the abstract.

Overall, “utilization of Stockholm3 improves the net benefit:harm ratio of PSA screening by identifying nearly all men with Gleason Grade 2 or higher, while minimizing the number of men undergoing biopsy who show no cancer or an indolent cancer (Gleason Grade 1),” Dr. Eggener said in an interview.
 

Stockholm3 Expected to be Available in U.S. This Year

The test, which has been available in Sweden since 2018, is expected to become commercially available in the United States in early 2024. Dr. Eggener noted that “cost of the test hasn’t been finalized, but will be considerably more expensive than PSA, which is very cheap.”

Commenting on the findings, Bradley McGregor, MD, of the Dana Farber Cancer Institute and an ASCO oncology expert, noted that “ultimately, the goal [of prostate screening] is to be able to better decide when a biopsy is going to yield a clinically relevant prostate cancer, [and] this study gives us some insight of the use of the Stockholm3 tool in a more diverse population.

“How the tool will be utilized in the clinic and in guidelines is something that is a work in progress,” he added. “But I think this provides some reassurances that this will have implications beyond just the homogeneous populations in the original studies.”

Dr. McGregor noted that considerations of the issue of cost should be weighed against the potential costs involved in unnecessary biopsies and a host of other costs that can arise with an inaccurate risk assessment.

“If there is a way to avoid those costs and help us have more confidence in the prostate test results and intervene at an earlier stage, I think that’s exciting,” he said.

Dr. Eggener has consulted for A3P Biomedical but had no financial relationship with the company to disclose.

That study showed significant improvement over PSA alone detection of prostate cancers with a Gleason score of at least 7 (P < .0001), Dr. Eggener explained.

The test combines five plasma protein markers, including total and free PSA, PSP94, GDF-15 and KLK2, along with 101 genetic markers and clinical patient data, including age, previous biopsy results and family history.

Because the Stockholm3 test was validated in a Swedish population cohort, evidence on the accuracy of the test in other racial and ethnic populations is lacking, the authors noted in the abstract.

Study Methods and Results

To further investigate, Dr. Eggener and his colleagues conducted the prospective SEPTA trial, involving 2,129 men with no known prostate cancer but clinical indications for prostate biopsy, who were referred for prostate biopsy at 17 North American sites between 2019 and 2023.

Among the men, 24% were self-identified as African American/Black; 46% were White/Caucasian; 14% were Hispanic/Latina; and 16% were Asian. The men’s median age was 63; their median PSA value was 6.1 ng/mL, according to the abstract.

Of the patients, 16% received magnetic resonance imaging (MRI)-targeted biopsies and 20% had prior benign biopsies, the abstract notes.

Biopsy results showed that clinically significant prostate cancer, defined as International Society of Urological Pathology (ISUP) Gleason Grade group ≥ 2, was detected in 29% of patients, with 14% having ISUP 1 cancer and 57% of cases having been benign, according to the abstract.

Overall detection rates of grade 2 or higher were 37% for African American/Black, 28% for White/Caucasian, 29% for Hispanic/Latino, and 21% Asian.

In terms of sensitivity of the two tests, the Stockholm3 (cut-point of ≥ 15) was noninferior compared with the traditional PSA cut-point of ≥ 4 ng/mL (relative sensitivity 0.95).

Results were consistent across ethnic subgroups: noninferior sensitivity (0.91-0.98) and superior specificity (2.51-4.70), the abstract authors reported.

Compared with the use of the PSA test’s cut-point of ≥ 4 ng/mL, the use of Stockholm3’s cut-point of ≥ 15 or higher would have reduced unnecessary biopsies by 45% overall, including by 46% among Asian and Black/African American patients, by 53% in Hispanic patients and 42% in White patients, according to the abstract.

Overall, “utilization of Stockholm3 improves the net benefit:harm ratio of PSA screening by identifying nearly all men with Gleason Grade 2 or higher, while minimizing the number of men undergoing biopsy who show no cancer or an indolent cancer (Gleason Grade 1),” Dr. Eggener said in an interview.
 

Stockholm3 Expected to be Available in U.S. This Year

The test, which has been available in Sweden since 2018, is expected to become commercially available in the United States in early 2024. Dr. Eggener noted that “cost of the test hasn’t been finalized, but will be considerably more expensive than PSA, which is very cheap.”

Commenting on the findings, Bradley McGregor, MD, of the Dana Farber Cancer Institute and an ASCO oncology expert, noted that “ultimately, the goal [of prostate screening] is to be able to better decide when a biopsy is going to yield a clinically relevant prostate cancer, [and] this study gives us some insight of the use of the Stockholm3 tool in a more diverse population.

“How the tool will be utilized in the clinic and in guidelines is something that is a work in progress,” he added. “But I think this provides some reassurances that this will have implications beyond just the homogeneous populations in the original studies.”

Dr. McGregor noted that considerations of the issue of cost should be weighed against the potential costs involved in unnecessary biopsies and a host of other costs that can arise with an inaccurate risk assessment.

“If there is a way to avoid those costs and help us have more confidence in the prostate test results and intervene at an earlier stage, I think that’s exciting,” he said.

Dr. Eggener has consulted for A3P Biomedical but had no financial relationship with the company to disclose.

The Stockholm3 (A3P Biomedical) multiparametic blood test has shown accuracy in assessing the risk of prostate cancer, exceeding that of the standard prostate-specific antigen (PSA)-based test, in Swedish patients. That improved accuracy was observed across diverse racial and ethnic groups, in a new study.

“The Stockholm3 outperformed the PSA test overall and in every subcohort, with an impressive reduction of unnecessary biopsies of 40% to 50%, while maintaining relative sensitivity,” first author Scott E. Eggener, MD, said in presenting the findings at the ASCO Genitourinary Cancers Symposium. The test “has attractive characteristics in a diverse cohort, including within various racial and ethnic subgroups,” added Dr. Eggener, professor of surgery and radiology at the University of Chicago.

While the PSA test, the standard-of-care in prostate cancer risk assessment, reduces mortality, the test is known to have a risk for false positive results, leading to unnecessary prostate biopsies, as well as overdiagnosis of low-risk prostate cancers, Dr. Eggener explained in his talk.

In ongoing efforts to better understand the predictive value of circulating tumor DNA (ctDNA) in cancer treatment response, new research shows ctDNA clearance following neoadjuvant treatment of muscle-invasive urothelial cancer is a better predictor of the risk of relapse than a 50% reduction in ctDNA variant allele frequency (VAF).

The combination of ctDNA with other baseline biomarkers shows further accuracy in predicting treatment response, the study also shows.

Matthew Nicholas Young, MD, of Barts Cancer Institute, London, presented the research at the ASCO Genitourinary Cancers Symposium.

“We found that ctDNA and tissue-based biomarkers improved biomarker accuracy,” Dr. Young, first author of the study, said at the meeting.

Furthermore, “ctDNA clearance is rare but appears more accurate than 50% reduction in VAF to predict response/relapse,” the authors said in their abstract.

“This is relevant for ongoing neoadjuvant trials planning to use this as an endpoint,” they wrote.

Dr. Young and his colleagues have previously shown ctDNA clearance to be an important predictive marker of treatment response or relapse.

To better understand the predictive value in combination with other biomarkers, as well as whether a reduction in ctDNA variant allele frequency could be used as a surrogate predictor of relapse compared with ctDNA clearance, the authors conducted an exploratory biomarker analysis of the phase 2, multicenter ABACUS trial.
 

Methods and Results

In the study, 95 patients with inoperable, muscle-invasive urothelial cancer who were either not eligible for or refused neoadjuvant cisplatin-based chemotherapy, each received two cycles of atezolizumab, followed by radical cystectomy.

Previously published results show the study met its primary endpoint of a pathological complete response (pCR) of 31%, and the 2-year disease-free survival and overall survival rates were 68% and 77%, respectively.

Of the 95 patients, 40 had sequential DNA analysis that could be evaluated in the current analysis; 43% of those patients achieved a pCR, while 20% experienced a relapse.

At baseline, 63% of patients were ctDNA-positive, and after treatment, 8% achieved ctDNA clearance, while 40% had a ctDNA response of a 50% VAF reduction.

All patients who had ctDNA clearance achieved pCR and none relapsed. In comparison, 30% of patients with a 50% VAF reduction experienced relapse and only 40% achieved pCR.

In terms of correlations with baseline biomarkers, the combination of ctDNA with activated T cells was significantly associated with outcomes (P = .02), as was the combination with PDL-1 status (P = .004).

However, combination with tumor mutation burden, already weak as a predictive biomarker, remained weak when combined with ctDNA status (P = .2), Dr. Young reported.

In terms of baseline expression of ctDNA, patients who were positive at baseline showed an increase in innate and adaptive immune signaling, in a profile aligning with increased PD-L1 at baseline in ctDNA-positive patients.

In addition, decreased immune signaling was observed in ctDNA-positive patients who relapsed.
 

Results May Be ‘Hypothesis-Generating’

Asked during the session whether the results imply that patients with no detectable ctDNA prior to the start of therapy may not need or benefit from neoadjuvant therapy, Dr. Young said the small sample size of ctDNA patients in the study was an important limitation.

“I think [the results] are hypothesis-generating, as we know that some patients will not benefit from neoadjuvant therapy and the goal of this work is to try to identify patterns among those who may not need treatment,” he said.

Of the patients with ctDNA analysis, “only those who were ctDNA-positive at baseline relapsed, [as well as] those who were ctDNA-positive following cystectomy, so I think [the possibility that a lack of detectable ctDNA prior to the start of therapy could suggest that the patient may not need or benefit from neoadjuvant therapy] is an interesting hypothesis that has come from this work,” Dr. Young said.

Overall, the findings show that, “in ctDNA-positive patients, increased immune signals appear to be associated with better outcomes with atezolizumab,” he concluded.

“Combining immune and circulating biomarkers may be required to accurately predict response to therapy,” Dr. Young added.

For patients with high-risk prostate cancer, treatment with long-term androgen deprivation therapy (ADT) and high-dose radiation was associated with significantly better progression-free, cancer-specific, and overall survival compared with ADT and standard-dose radiation.
The investigators also found that the patients taking long-term ADT and high-dose radiation did not experience additional late urinary tract or gastrointestinal toxicities. Christophe Hennequin, MD, PhD, reported these and other findings of the Radiation Therapy in Treating Patients Receiving Hormone Therapy for Prostate Cancer (GETUG-AFU 18) trial, at the 2024 American Society for Clinical Oncology (ASCO) Genitourinary Cancers Symposium.  
Among 505 patients randomly assigned to be treated with radiation therapy (RT) at either the standard 70 Gy dose or a high, 80 Gy dose followed by 3 years of adjuvant  ADT, the 10-year progression-free survival (PFS) rate was 83.6% for patients who had received the 80 Gy dose, vs. 72.2% for patients who had received the 70 Gy dose. This translated into a hazard ratio (HR) for biochemical or clinical progression of 0.56 (P = .0005). 
This PFS advantage for high-dose radiation was also reflected by an overall survival (OS) advantage, with 10-year OS rates of 77% vs. 65.9%, respectively, translating into a 39% reduction in risk of death (HR 0.61, P = .0039) for patients who had received the higher radiation dose, reported Dr. Hennequin, of the Hospital Saint Louis in Paris, France. 
"We have now Level 1 evidence that high-dose RT with long-term ADT must be the standard of care in high-risk prostate cancer patients," he said at the meeting. 
Dr. Hennequin noted that significantly more patients assigned to high-dose RT were treated with intensity modulated radiation therapy (IMRT) rather than conventional beam radiation, and emphasized that the superior results seen with the higher dose is likely due to the use of IMRT. 

Prior evidence 

Dr. Hennequin pointed to a meta-analysis published in The Lancet in 2022 which showed that among nearly 11,000 patients with a median follow-up of 11.4 years the addition of ADT to RT significantly improved metastasis-free survival, and that longer ADT reduced the risk of metastases by 16% compared with standard schedule ADT. 
He also cited the DART 01/05 trial results, which were published in 2022 in The Lancet: Oncology, which found a clinically relevant benefit for 24 months vs. 4 months of adjuvant ADT following a minimum of 76 Gy radiation in patients with high-risk disease, but not among patients with intermediate-risk disease.   
The GETUG-AFU 18 trial was designed to address the question of whether 80 Gy of radiation could improve outcomes compared with 70 Gy in patients treated with long-term ADT. 

Study details and results 

The investigators enrolled men with high-risk prostate cancer defined as either a prostate-specific antigen (PSA) level 20 ng/ml or greater, Gleason score 8 or higher, or clinical stage T3 or T4 disease, and after stratification by treatment center and lymph node resection randomly assigned them to receive either 70 Gy or 80 Gy RT followed by 3 years of ADT. 
Approximately two-thirds of the patients in each study arm had one risk factor and about one-fourth had two risk factors. The remaining patients had all three high-risk defining factors.  
Approximately 16.5% of patients in each arm had undergone lymph node dissection.  
The median ADT duration was 33.4 months. In all, 82.9% of patients underwent pelvic lymph node radiation; lymph node radiation was not performed in those patients who had negative node dissection results. 
Significantly more patients assigned to the 80 Gy dose were treated with IMRT (80.6% vs. 58.6%, P < .001).   
The cancer-specific survival rate was also higher for the group receiving the 80 Gy dose, with a 10 year rate of 95.6% vs. 90% for patients treated with 70 Gy. This difference translated into a HR of 0.48 (P = .0090).  
 

Comparable safety 

The safety analysis, which included 248 patients who received 80 Gy and 251 who received 70 Gy, showed that the incidence rates of both late genitourinary and gastrointestinal toxicities were low and comparable between the groups. Grade 3 or greater late genitourinary toxicities were seen in 2.0% of patients treated with 80 Gy and 3.2% of those treated with 70 Gy. In both arms, only 1.6% of patients had grade 3 or greater later GI toxicities.  
There were also no differences between the study arms in patient-reported quality of life measures related to either bowel or urinary symptoms. 
Invited discussant Neha Vapiwala, MD, FACR, from Penn Medicine in Philadelphia commented that the results of the GETUG-AFU 18 trial suggest that "if you had even lower-dose systemic therapy that the radiation control at the local level - local-regional level in this case - can in fact contribute to the prevention of distant metastases and can contribute to cancer-specific survival." 
She said that with the efficacy results and the comparable toxicity and quality of life measures, dose-escalated radiation therapy and long-term ADT appear to offer a synergistic benefit. 
The results are "practice-affirming for many, perhaps practice-changing for some if you're not already offering this," she said.

For patients with high-risk prostate cancer, treatment with long-term androgen deprivation therapy (ADT) and high-dose radiation was associated with significantly better progression-free, cancer-specific, and overall survival compared with ADT and standard-dose radiation.
The investigators also found that the patients taking long-term ADT and high-dose radiation did not experience additional late urinary tract or gastrointestinal toxicities. Christophe Hennequin, MD, PhD, reported these and other findings of the Radiation Therapy in Treating Patients Receiving Hormone Therapy for Prostate Cancer (GETUG-AFU 18) trial, at the 2024 American Society for Clinical Oncology (ASCO) Genitourinary Cancers Symposium.  
Among 505 patients randomly assigned to be treated with radiation therapy (RT) at either the standard 70 Gy dose or a high, 80 Gy dose followed by 3 years of adjuvant  ADT, the 10-year progression-free survival (PFS) rate was 83.6% for patients who had received the 80 Gy dose, vs. 72.2% for patients who had received the 70 Gy dose. This translated into a hazard ratio (HR) for biochemical or clinical progression of 0.56 (P = .0005). 
This PFS advantage for high-dose radiation was also reflected by an overall survival (OS) advantage, with 10-year OS rates of 77% vs. 65.9%, respectively, translating into a 39% reduction in risk of death (HR 0.61, P = .0039) for patients who had received the higher radiation dose, reported Dr. Hennequin, of the Hospital Saint Louis in Paris, France. 
"We have now Level 1 evidence that high-dose RT with long-term ADT must be the standard of care in high-risk prostate cancer patients," he said at the meeting. 
Dr. Hennequin noted that significantly more patients assigned to high-dose RT were treated with intensity modulated radiation therapy (IMRT) rather than conventional beam radiation, and emphasized that the superior results seen with the higher dose is likely due to the use of IMRT. 

Prior evidence 

Dr. Hennequin pointed to a meta-analysis published in The Lancet in 2022 which showed that among nearly 11,000 patients with a median follow-up of 11.4 years the addition of ADT to RT significantly improved metastasis-free survival, and that longer ADT reduced the risk of metastases by 16% compared with standard schedule ADT. 
He also cited the DART 01/05 trial results, which were published in 2022 in The Lancet: Oncology, which found a clinically relevant benefit for 24 months vs. 4 months of adjuvant ADT following a minimum of 76 Gy radiation in patients with high-risk disease, but not among patients with intermediate-risk disease.   
The GETUG-AFU 18 trial was designed to address the question of whether 80 Gy of radiation could improve outcomes compared with 70 Gy in patients treated with long-term ADT. 

Study details and results 

The investigators enrolled men with high-risk prostate cancer defined as either a prostate-specific antigen (PSA) level 20 ng/ml or greater, Gleason score 8 or higher, or clinical stage T3 or T4 disease, and after stratification by treatment center and lymph node resection randomly assigned them to receive either 70 Gy or 80 Gy RT followed by 3 years of ADT. 
Approximately two-thirds of the patients in each study arm had one risk factor and about one-fourth had two risk factors. The remaining patients had all three high-risk defining factors.  
Approximately 16.5% of patients in each arm had undergone lymph node dissection.  
The median ADT duration was 33.4 months. In all, 82.9% of patients underwent pelvic lymph node radiation; lymph node radiation was not performed in those patients who had negative node dissection results. 
Significantly more patients assigned to the 80 Gy dose were treated with IMRT (80.6% vs. 58.6%, P < .001).   
The cancer-specific survival rate was also higher for the group receiving the 80 Gy dose, with a 10 year rate of 95.6% vs. 90% for patients treated with 70 Gy. This difference translated into a HR of 0.48 (P = .0090).  
 

Comparable safety 

The safety analysis, which included 248 patients who received 80 Gy and 251 who received 70 Gy, showed that the incidence rates of both late genitourinary and gastrointestinal toxicities were low and comparable between the groups. Grade 3 or greater late genitourinary toxicities were seen in 2.0% of patients treated with 80 Gy and 3.2% of those treated with 70 Gy. In both arms, only 1.6% of patients had grade 3 or greater later GI toxicities.  
There were also no differences between the study arms in patient-reported quality of life measures related to either bowel or urinary symptoms. 
Invited discussant Neha Vapiwala, MD, FACR, from Penn Medicine in Philadelphia commented that the results of the GETUG-AFU 18 trial suggest that "if you had even lower-dose systemic therapy that the radiation control at the local level - local-regional level in this case - can in fact contribute to the prevention of distant metastases and can contribute to cancer-specific survival." 
She said that with the efficacy results and the comparable toxicity and quality of life measures, dose-escalated radiation therapy and long-term ADT appear to offer a synergistic benefit. 
The results are "practice-affirming for many, perhaps practice-changing for some if you're not already offering this," she said. 

Officials at Dana-Farber Cancer Institute are moving to retract at least six published research papers and correct 31 others amid allegations of data manipulation.

News of the investigation follows a blog post by British molecular biologist Sholto David, MD, who flagged almost 60 papers published between 1997 and 2017 that contained image manipulation and other errors. Some of the papers were published by Dana-Farber’s chief executive officer, Laurie Glimcher, MD, and chief operating officer, William Hahn, MD, on topics including multiple myeloma and immune cells.

Mr. David, who blogs about research integrity, highlighted numerous errors and irregularities, including copying and pasting images across multiple experiments to represent different days within the same experiment, sometimes rotating or stretching images.

In one case, Mr. David equated the manipulation with tactics used by “hapless Chinese papermills” and concluded that “a swathe of research coming out of [Dana-Farber] authored by the most senior researchers and managers appears to be hopelessly corrupt with errors that are obvious from just a cursory reading the papers.” 

“Imagine what mistakes might be found in the raw data if anyone was allowed to look!” he wrote.

Barrett Rollins, MD, PhD, Dana-Farber Cancer Institute’s research integrity officer, declined to comment on whether the errors represent scientific misconduct, according to STAT. Rollins told ScienceInsider that the “presence of image discrepancies in a paper is not evidence of an author’s intent to deceive.” 

Access to new artificial intelligence tools is making it easier for data sleuths, like Mr. David, to unearth data manipulation and errors. 

The current investigation closely follows two other investigations into the published work of Harvard University’s former president, Claudine Gay, and Stanford University’s former president, Marc Tessier-Lavigne, which led both to resign their posts.

Men with localized prostate cancer face a number of treatment choices, including radical prostatectomy, radiotherapy with or without androgen deprivation therapy, and active surveillance. Understanding the likely functional outcomes of each treatment over time is important, as most patients are expected to live at least 15 years after diagnosis.

New research published Jan. 23 in JAMA parses functional outcome results from a population-based study of men diagnosed with localized prostate cancer. For their research, Bashir Al Hussein Al Awamlh, MD, of Vanderbilt University in Nashville, Tennessee, and his colleagues, looked at sexual function, urinary health, bowel function, hormonal function, and other outcomes in this cohort at 10 years’ follow-up.

Among 2455 patients for whom 10-year data were available, 1877 were deemed at baseline to have a favorable prognosis (defined as cT1-cT2bN0M0, prostate-specific antigen level less than 20 ng/mL, and grade group 1-2) and 568 had unfavorable-prognosis prostate cancer (defined as cT2cN0M0, prostate-specific antigen level of 20-50 ng/mL, or grade group 3-5). Follow-up data were collected by questionnaire through February 1, 2022. The men in the study were all younger than 80 years, and three-quarters of them were White.

At 10 years, outcomes differed based on the amount of time that had passed since diagnosis (they found different results at 3 and 5 year follow up, for example) and which treatment a patient received.

Among men with favorable prognoses at diagnosis, 20% underwent active surveillance for at least 1 year, while 56% received radical prostatectomy, 19% had external beam radiotherapy (EBRT) without ADT, and 5% had brachytherapy. Nearly a third of men originally opting for surveillance went on to undergo a therapeutic intervention by 10 years.

Dr. Al Hussein Al Awamlh and his colleagues found that while 3- and 5-year follow-up studies in this cohort had shown declines in sexual function among men who underwent surgery compared with those who had radiation or active surveillance, by 10 years those differences had faded, with no clinically meaningful differences in sexual function scores between the surgery and surveillance groups. In an interview, Dr. Al Hussein Al Awamlh said that this finding likely reflected mainly age-related declines in function across the study population — though it could also reflect declines after converting from surveillance to surgery or gradual decline with radiation treatment, he acknowledged.

Men with favorable prognoses at baseline who underwent surgery saw significantly worse urinary incontinence at 10 years compared with those started on radiotherapy or active surveillance. And EBRT was associated with fewer incontinence issues compared with active surveillance.

Among the group of men with an unfavorable prognosis at baseline, 64% of whom underwent radical prostatectomy and 36% EBRT with ADT, surgery was associated with worse urinary incontinence but not worse sexual function throughout 10 years of follow up, compared to radiotherapy with androgen deprivation therapy.

Radiation-treated patients with unfavorable prognoses, meanwhile, saw significantly worse bowel function and hormone function at 10 years compared with patients who had undergone surgery.

Dr. Al Hussein Al Awamlh said that a strength of this study was that “we had enough patients to stratify functional outcomes based on disease prognosis.” Another key finding was that some of the outcomes changed over time. “For example, among the patients with unfavorable prognoses, at 10-year follow-up there was slightly worse bowel and hormone function seen associated with radiation with ADT compared with surgery,” he said — something not seen at earlier follow-up points.

The findings may help offer a more nuanced way to counsel patients, Dr. Al Hussein Al Awamlh noted. For example, the side effects associated with sexual function “are not as relevant for those with unfavorable disease,” he said.

While current prostate cancer guidelines do address quality of life in shared decision-making, he said, “hopefully this data may provide more insight on that.” For patients with favorable prognosis, the findings reinforce that “active surveillance is a great option because it avoids the effects associated with those other treatments.”

Ultimately, Dr. Al Hussein Al Awamlh said, “this is a patient preference issue. It’s important for patients to understand how different functions are affected and to decide what is better for them — what they can live with and what they cannot, provided all the options are oncologically safe.”

The study authors disclosed as limitations of their study its observational design, the potential for response bias among study participants, and small numbers for some of the measured outcomes.

In an interview, urologist Mark S. Litwin, MD, of the University of California Los Angeles, characterized the study as “a well-conducted very-long-term longitudinal cohort that tracked men long past the initial diagnosis and treatment. That empowered the Vanderbilt team to find differences in quality of life many years later and compare them to other older men who had not received treatment.”

The new findings, Dr. Litwin said, “are critical in showing that most men with prostate cancer do not die from it; hence, the quality-of-life effects end up being the key issues for decision-making.”

Dr. Al Hussein Al Awamlh and colleagues’ study was funded by grants from the National Institutes of Health, the Agency for Healthcare Research and Quality, and the Patient-Centered Outcomes Research Institute. Several coauthors disclosed funding from pharmaceutical and/or device manufacturers. Dr. Litwin disclosed no conflicts of interest related to his comment.

TOPLINE:

In middle-aged and older men with hypogonadism, excluding those at high prostate cancer risk, testosterone replacement therapy (TRT) showed low rates of adverse prostate events, including cancer.

METHODOLOGY:

• Uncertainty and concern exist about a link between prostate cancer risk and testosterone levels. Most professional society guidelines recommend against TRT in men with a history of or an increased risk for prostate cancer.
• The Testosterone Replacement Therapy for Assessment of Long-Term Vascular Events and Efficacy Response in Hypogonadal Men  included 5204 men (ages 45-80, 17% Black, 80% White), randomly assigned to receive testosterone gel or placebo.
• Men with a history of cardiovascular disease or increased cardiovascular risk were evaluated to exclude those at increased prostate cancer risk (fasting testosterone < 300 ng/dL, ≥ 1 hypogonadal symptoms).
• The primary prostate safety endpoint was high-grade prostate cancer incidence (Gleason score, ≥ 4 + 3).
• Secondary endpoints were incidences of any prostate cancer, acute urinary retention, invasive procedure for benign prostatic hyperplasia, prostate biopsy, and new pharmacologic treatment for lower urinary tract symptoms.

TAKEAWAY:

• During 14,304 person-years of follow-up, high-grade prostate cancer incidence did not differ significantly between the TRT and placebo (0.19% vs 0.12%; P = .51) groups.
• The incidences of prostate cancer, acute urinary retention, invasive procedures for benign prostatic hyperplasia, prostate biopsy, and new pharmacologic treatment for lower urinary tract symptoms were also similar between the groups.
• TRT did not lead to an increase in lower urinary tract symptoms.
• The increase in prostate-specific antigen (PSA) levels was higher in the TRT group than in the placebo group (P < .001). However, the between-group difference did not widen after 12 months.

IN PRACTICE:

For “clinicians and patients who are considering testosterone replacement therapy for hypogonadism,” wrote the authors, “the study’s findings will facilitate a more informed appraisal of the potential prostate risks of testosterone replacement therapy.”

SOURCE:

Shalender Bhasin, MB, BS, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, led the study. It was published online in JAMA Network Open.

LIMITATIONS:

• The study findings do not apply to men with known prostate cancer or higher PSA values or those without confirmed hypogonadism.
• Although the TRAVERSE study was longer than many contemporary trials, carcinogens may require many years to induce malignant neoplasms.
• The trial’s structured evaluation of men after PSA testing did not include prostate imaging or other biomarker tests, which could affect the decision to perform a biopsy.

DISCLOSURES:

This study was funded by a consortium of testosterone manufacturers led by AbbVie Inc with additional financial support from Endo Pharmaceuticals, Acerus Pharmaceuticals Corp, and Upsher-Smith Laboratories. Mr. Bhasin and two coauthors declared receiving grants, consulting and personal fees, and other ties with pharmaceutical and device companies and other sources.

• The incidences of prostate cancer, acute urinary retention, invasive procedures for benign prostatic hyperplasia, prostate biopsy, and new pharmacologic treatment for lower urinary tract symptoms were also similar between the groups.
• TRT did not lead to an increase in lower urinary tract symptoms.
• The increase in prostate-specific antigen (PSA) levels was higher in the TRT group than in the placebo group (P < .001). However, the between-group difference did not widen after 12 months.

IN PRACTICE:

For “clinicians and patients who are considering testosterone replacement therapy for hypogonadism,” wrote the authors, “the study’s findings will facilitate a more informed appraisal of the potential prostate risks of testosterone replacement therapy.”

SOURCE:

Shalender Bhasin, MB, BS, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, led the study. It was published online in JAMA Network Open.

LIMITATIONS:

• The study findings do not apply to men with known prostate cancer or higher PSA values or those without confirmed hypogonadism.
• Although the TRAVERSE study was longer than many contemporary trials, carcinogens may require many years to induce malignant neoplasms.
• The trial’s structured evaluation of men after PSA testing did not include prostate imaging or other biomarker tests, which could affect the decision to perform a biopsy.

DISCLOSURES:

This study was funded by a consortium of testosterone manufacturers led by AbbVie Inc with additional financial support from Endo Pharmaceuticals, Acerus Pharmaceuticals Corp, and Upsher-Smith Laboratories. Mr. Bhasin and two coauthors declared receiving grants, consulting and personal fees, and other ties with pharmaceutical and device companies and other sources.

Radiation oncologists from the largest professional societies have come together to lobby for Medicare payment reform.

The American Society for Radiation Oncology (ASTRO) recently announced its partnership with three other groups — the American College of Radiation Oncology, the American College of Radiology, and the American Society of Clinical Oncology — to change how the specialty is paid for services. 

Over the past decade, radiation oncologists have seen a 23% drop in Medicare reimbursement for radiation therapy services, with more cuts to come, according to a press release from ASTRO.

Traditionally, Medicare has reimbursed on the basis of the fraction of radiation delivered. But with moves toward hypofractionated regimens, deescalated therapy, and other changes in the field, reimbursement has continued to dwindle. 

The cuts have led to practice consolidation and closures that threaten patient access especially in rural and underserved areas, a spokesperson for the group told this news organization.

To reverse this trend, ASTRO recently proposed the Radiation Oncology Case Rate program, a legislative initiative to base reimbursements on patient volumes instead of fractions delivered. 

ASTRO is currently drafting a congressional bill to change the current payment structure, which “has become untenable,” the spokesperson said.

Medicare will now cover the use of an AI-based test for prostate cancer that can predict which men will benefit from potentially disabling androgen deprivation therapy.

The Centers for Medicare & Medicare Services (CMS) on January 1 approved the payment rate for ArteraAI as a clinical diagnostic laboratory test. The test is the first that can both predict therapeutic benefit and prognosticate long-term outcomes in localized prostate cancer. 

Daniel Spratt, MD, chair of radiation oncology at UH Seidman Cancer Center in Cleveland, who has been involved in researching ArteraAI, told this news organization that the test improves risk stratification or prognostication over standard clinical and pathologic tools, such as prostate-specific antigen, Gleason score, and T-stage, or risk groupings such as those from the National Comprehensive Cancer Network (NCCN).

“Medicare approval allows this test to reach more patients without the financial burden of covering the test out of pocket. The test is found among other tests in NCCN guidelines as a tool to improve risk stratification and personalization of treatment,” said Dr. Spratt, who serves on the network’s prostate cancer panel.

ArteraAI combines a patient’s standard clinical and pathologic information into an algorithm, alongside a digitized image analysis of the patients’ prostate biopsy. The result is a score that estimates a patient’s risk of developing metastasis or dying from prostate cancer.

Dr. Spratt was the lead author of article last June in NEJM Evidence that validated ArteraAI. He said ArteraAI is 80% accurate as a prognostic test compared with 65% accuracy using NCCN stratification systems. 

The AI test spares about two thirds of men with intermediate-risk prostate cancer who are starting radiation therapy from androgen deprivation and its side effects, such as weight gain, breast enlargement, hot flashes, heart disease, and brain problems, Dr. Spratt added. 

Andre Esteva, CEO and co-founder of San Francisco-based ArteraAI, said, “After someone is diagnosed with localized prostate cancer, deciding on a treatment can feel very overwhelming as there are so many factors to consider. During this time, knowledge is power, and having detailed, personalized information can increase confidence when making these challenging decisions. The ArteraAI Prostate Test was developed with this in mind and can predict whether a patient will benefit from hormone therapy and estimate long-term outcomes.”

Bruno Barrey is one of Dr. Spratt’s patients. Barrey, a robotics engineer from suburban Detroit who was transitioning from active surveillance with Gleason 3+4 intermediate-risk prostate cancer to radiation therapy, said, “I was concerned about the side effects from androgen-deprivation therapy. I was relieved that the AI test allowed me to avoid hormone therapy.”

Dr. Spratt reported working with NRG Oncology, a clinical trials group funded by the National Cancer Institute, and as an academic collaborator with ArteraAI.
