Renal Cell Carcinoma

In a southwestern U.S. population having renal cell carcinoma (RCC), patient and disease characteristics differ by race/ethnicity in ways that may have implications for prevention, diagnosis, prognosis, and treatment, finds a single-center cohort study.

Investigators led by Ken Batai, PhD, of University of Arizona, Tucson, retrospectively reviewed the medical records of 294 patients with RCC as their first cancer who underwent partial or radical nephrectomy: 151 European Americans, 95 Hispanic Americans, 22 Native Americans, 9 African Americans, and 17 other race/ethnicity. About 12% overall had metastases at presentation.

On average, compared with European Americans, Hispanic Americans were about 5 years younger at diagnosis (55.8 vs. 60.5) and had higher odds of diagnosis before the age of 50 (odds ratio, 2.77), according to results published in Clinical Genitourinary Cancer.

Native Americans were even younger (49.7) and had dramatically elevated odds of diagnosis before that age (odds ratio, 6.23).

Relative to their European American counterparts, Hispanic Americans less commonly smoked (30.5% vs 48.6%) and African Americans more commonly had chronic kidney disease (37.5% vs. 5.8%). Both groups had higher prevalence of diabetes (45.6% and 54.5% vs. 21.7%). In addition, Native Americans had higher body mass index (35.2 vs. 30.7).

Clear cell histology was seen in 78.8% of European Americans, but in 92.6% of Hispanic Americans (odds ratio, 2.79) and 86.4% of Native Americans. African Americans more commonly had stage III or IV disease at diagnosis (77.8% vs. 35.3%; odds ratio, 6.51), but the racial/ethnic groups did not differ significantly on grade, tumor size, or presence of necrosis.

Among the Hispanic American patients undergoing radical nephrectomy, disease was more commonly of stage III or IV at diagnosis in those who were aged 65 or older (odds ratio, 10.48) and those who spoke Spanish as their primary language (odds ratios, 4.61).

The reasons for the observed racial/ethnic disparities remain unclear, according to Dr. Batai and his coinvestigators. Nonetheless, “it is necessary to better understand the clinical characteristics of these underserved Hispanic American and Native American populations with high kidney cancer burden,” they wrote.

“Our findings can direct future research toward elucidating the difference in tumor behavior among the different ethnic groups and health care issues causing poor outcomes,” they concluded. The findings also “bring ... awareness to practitioners treating patients from these racial/ethnic minority groups regarding the clinical characteristics and underlying issues in these patient populations.”

The study was supported by the American Cancer Society and the Partnership for Native American Cancer Prevention.

High expression of karyopherin alpha 2 (KPNA2), a carrier protein that helps shuttle cancer-associated proteins from the nucleus to the cytoplasm, is an adverse prognostic factor in patients with clear cell or papillary renal cell carcinoma (RCC), according to a retrospective cohort study.

Senior author Glen Kristiansen, MD, director of the Institute of Pathology at the University Hospital Bonn (Germany), and his colleagues assessed tumor levels of KPNA2 protein by immunohistochemistry in 240 clinic patients with RCC (217 with clear cell histology, 23 with papillary histology). They also assessed tumor levels of KPNA2 mRNA in 771 patients with RCC (481 with clear cell histology, 290 with papillary cell histology) using publicly available gene expression data from the Cancer Genome Atlas (CGA).

Overall, 19% of the clinic patients’ tumors showed high expression of KPNA2 protein, according to results reported in Clinical Genitourinary Cancer. In addition, 26% of the CGA patients’ tumors showed high expression of KPNA2 mRNA.

Among patients with clear cell RCC, those with high tumor levels of KPNA2 protein survived roughly half as long as counterparts with low levels or none (74 months vs. 171 months); the difference was significant in univariate analysis (P = .012) but not in multivariate analysis that included well-known prognostic factors (HR, 1.491; P = .237). On the other hand, those with high tumor levels of KPNA2 mRNA had an elevated risk of death in both univariate analysis (HR, 2.31; P less than .001) and multivariate analysis (HR, 1.45; P = .035).

Among patients with papillary RCC, tumor levels of KPNA2 protein were not significantly associated with survival. However, those with high tumor levels of KPNA2 mRNA had a sharply elevated risk of death in both univariate analysis (HR, 9.7; P less than .001) and multivariate analysis (HR, 6.2; P = .004).

KPNA2 expression “represents a novel prognostic factor in these subtypes of RCC,” concluded Dr. Kristiansen and his coinvestigators. Therefore, this biomarker “could be used to stratify risk groups within RCC.” Collectively, the study’s findings suggest that KPNA2 is involved in both the pathogenesis and the progression of RCC. Given evidence that it helps transport p53 and fibroblast growth factor 2 at least in tumors with clear cell histology, “investigation of the nucleocytoplasmic transport through KPNA2 in [clear cell] RCC is an important task for future studies to better understand the link between elevated KPNA2 expression and altered biological processes like proliferation, cell growth, migration, invasion and tumor formation in RCC. In addition, examination of other members of [the] karyopherin-alpha family could elucidate the role of the nucleocytoplasmic transport system in pathogenesis of RCC.”

The authors reported that they had no conflict of interests.

While adjuvant axitinib failed to improve disease-free survival in a recent phase 3 renal cell carcinoma (RCC) trial, the highest-risk subgroup appeared to benefit, according to a report on the study.

The phase 3 ATLAS trial was stopped early because of a lack of benefit for axitinib versus placebo in the study, which included patients with locoregional RCC at risk of recurrence after nephrectomy.

However, a prespecified analysis showed that axitinib reduced risk of disease-free survival events by about one-third in the highest-risk subset of patients, according to investigator David I. Quinn, MD, USC Norris Comprehensive Cancer Center, Los Angeles, and colleagues.

That finding tracks with results of the earlier S-TRAC trial, in which patients at high risk of tumor recurrence after nephrectomy had significantly longer disease-free survival with sunitinib versus placebo, Dr. Quinn and coauthors said.

“Taken together, these results support that patients at highest risk for RCC recurrence benefit from adjuvant treatment,” they wrote in Annals of Oncology.

In the ATLAS trial, Dr. Quinn and coinvestigators at 137 centers in eight countries enrolled 724 adults with newly diagnosed renal cell carcinoma (greater than or equal to pT2 and/or N+, any Fuhrman grade) with Eastern Cooperative Oncology Group status of 0 or 1 and prior nephrectomy.

Patients were randomly assigned to oral, twice-daily axitinib 5 mg or placebo for up to 3 years of treatment, and at least 1 year of treatment provided there was no recurrence, substantial toxicity, or withdrawal of consent.

For the primary endpoint, disease-free survival per independent review committee assessment, the hazard ratio was 0.870 (95% confidence interval, 0.660-1.147; P = .3211), according to the report. Disease-free survival as rated by investigators showed a somewhat larger but still not statistically significant reduction in risk of an event, Dr. Quinn and colleagues said.

However, in the prespecified subgroup analyses, the patients at highest risk (pT3 with Fuhrman grade greater than or equal to 3 or pT4 and/or N+, any T, any Fuhrman grade) had a reduction of risk with hazard ratios of 0.735 per independent review committee (P = .0704) and 0.641 per investigator (P = .0051).

The ATLAS study was designed before results of the S-TRAC study were known, and so patients at lower risk of recurrence were included, said Dr. Quinn and coauthors.

Ongoing trials are looking at sorafenib, everolimus, and immune checkpoint inhibitors in the adjuvant RCC setting, they noted in their discussion of ATLAS, S-TRAC, and other investigations.

Results from these trials may provide clarification on the future of adjuvant treatment for RCC, and whether angiogenesis inhibition is the key mechanism to obtain a reduction in risk of relapse after nephrectomy,” they said.

The study was sponsored by Pfizer and SFJ Pharmaceuticals. Dr. Quinn reported providing advisory board services for Pfizer, Bayer, Novartis, Bristol-Myers Squibb, Merck, Exelixis, Genentech, Roche, AstraZeneca, and Astellas. Coauthors reported disclosures related to Bristol-Myers Squibb, Ipsen, MSD, Novartis, Pfizer, and Roche, among others.

MUNICH – The combination of the immune checkpoint inhibitor avelumab (Bavencio) and the tyrosine kinase inhibitor axitinib (Inlyta) was associated with longer progression-free survival and higher objective response rates than was sunitinib as frontline therapy for patients with advanced renal cell carcinoma, investigators found.

Neil Osterweil/MDedge News

The progression-free survival (PFS) benefit of the combination was seen both in the subset of patients with tumors expressing programmed death-1 ligand 1 (PD-L1) on at least 1% of their cells as well as in the overall study population, reported Robert J. Motzer, MD, of Memorial Sloan Kettering Cancer Center, New York, on behalf of colleagues in the JAVELIN Renal 101 trial.

“This was very early on, at an interim analysis, showing a profound effect,” he said at a briefing prior to his presentation of the data in a presidential symposium at the European Society for Medical Oncology Congress.

“The results support this being a new first-line standard of care, and possibly a first-line option for advanced RCC based on these data,” he added.

Briefing discussant John Haanen, PhD, of the Netherlands Cancer Institute in Amsterdam, said that “based on preclinical data, it makes sense to combine angiogenesis inhibitors and immunotherapy, because we know angiogenesis, VEGF [vascular endothelial growth factor] especially impacts on the way the immune system can respond to the kidney cancer, and by taking away some of these negative effects of the VEGF by using an anti-VEGF drug, the immunotherapy may work better,” he said.

There was no difference in the incidence of adverse events in a group of patients being treated with pazopanib for metastatic renal cell carcinoma with comorbid renal dysfunction.

In a multicenter, retrospective study that included 229 patients with or without renal insufficiency being treated for metastatic renal cell carcinoma with pazopanib, no significant differences were found in the incidence of adverse events between groups. Similar results were demonstrated for both efficacy parameters, progression-free survival, and overall survival (P = .6), Cristina Masini, MD, of AUSL-IRCCS in Reggio Emilia, Italy, and colleagues reported in Clinical Genitourinary Cancer.

The researchers also determined that dose reductions occurred more often in patients with renal insufficiency, compared with those that were renal competent (52% vs. 36%; P = .04).

The majority of study participants received a starting dose of 800 mg daily of pazopanib, which was reduced to a minimum of 200 mg daily in 19% of participants from the renal impairment group, compared with less than 1% in the nonrenally impaired group.

“The similar efficacy and safety displayed by pazopanib in patients with poor renal function, compared with those with normal function may have a major relevance for therapy individualization in clinical practice,” the investigators concluded, adding that, because of the retrospective study design, further research is needed to fully establish any causal links between pazopanib and renal insufficiency.

The authors reported that editorial assistance was supported by Novartis. No other conflict of interests were reported

Similar results were demonstrated for both efficacy parameters, progression-free survival, and overall survival (P = .6), Cristina Masini, MD, of AUSL-IRCCS in Reggio Emilia, Italy, and colleagues reported in Clinical Genitourinary Cancer.

The researchers also determined that dose reductions occurred more often in patients with renal insufficiency, compared with those that were renal competent (52% vs. 36%; P = .04).

The majority of study participants received a starting dose of 800 mg daily of pazopanib, which was reduced to a minimum of 200 mg daily in 19% of participants from the renal impairment group, compared with less than 1% in the nonrenally impaired group.

“The similar efficacy and safety displayed by pazopanib in patients with poor renal function, compared with those with normal function may have a major relevance for therapy individualization in clinical practice,” the investigators concluded, adding that, because of the retrospective study design, further research is needed to fully establish any causal links between pazopanib and renal insufficiency.

The authors reported that editorial assistance was supported by Novartis. No other conflict of interests were reported

In contrast to other recent studies, androgen deprivation therapy (ADT) had no link to dementia in a observational cohort study of more than 45,000 men with prostate cancer who received definitive radiotherapy, investigators have reported.

No significant associations were found between ADT and Alzheimer’s disease or vascular dementia, or between shorter or longer courses of ADT and any dementia studied, according to Rishi Deka, PhD, of Veterans Affairs San Diego Health Care System, La Jolla, Calif., and coinvestigators.

“These results may mitigate concerns regarding the long-term risks of ADT on cognitive health in the treatment of prostate cancer,” Dr. Deka and colleagues wrote in JAMA Oncology.

Two other recent studies showed strong, statistically significant associations between ADT and dementia in prostate cancer. However, those studies combined patients with local and metastatic disease, receiving ADT in the upfront or recurrent settings, while the present study looked specifically at men with nonmetastatic prostate cancer who received radiotherapy.

“Different treatment modalities and disease stages are associated with substantial selection bias that may predispose results to false associations,” noted Dr. Deka and coauthors.

Their observational cohort study comprised 45,218 men diagnosed with nonmetastatic prostate cancer at the U.S. Department of Veterans Affairs who underwent radiotherapy with or without ADT. The investigators excluded men who had a diagnosis of dementia within 1 year of the prostate cancer diagnosis or who had prior diagnoses of dementia, stroke, or cognitive impairment.

A total of 1,497 patients were diagnosed with dementia over a median of 6.8 years of follow-up: 404 with Alzheimer disease, 335 with vascular dementia, and 758 with other types or unclassified dementias.

The investigators found no significant association between use of ADT and development of any dementia, the primary outcome of the analysis (subdistribution hazard ratio [SHR], 1.04; 95% confidence interval, 0.94-1.16; P = .43).

Likewise, there was no association between ADT and vascular dementia, specifically, with an SHR of 1.20 (95% CI, 0.97-1.50; P = .10) or Alzheimer’s disease, with an SHR of 1.11 (95% CI, 0.91-1.36; P = .29).

Duration of ADT longer than 1 year was not significantly associated with dementia, nor was duration shorter than 1 year, with SHRs, of 1.08 and 1.01 respectively, the analysis shows.

The SHRs in these and other analysis reported ranged from 1.00 to 1.21. That is substantially lower than hazard ratios of 1.66 to 2.32 in one previous study linking ADT to dementia, according to the investigators, suggesting that the results of the current analysis were not due to inadequate power to detect differences.

Nevertheless, the findings may not be generalizable to some other populations, they cautioned, since it was focused demographically on veterans, and was limited to radiotherapy-treated patients.

Dr. Deka and coauthors reported no conflict of interest. Their study was funded by grants from the University of California San Diego Center for Precision Radiation Medicine.

Renal cell carcinoma (RCC) incidence rates increased in recent years, but have stabilized, while mortality rates have dropped precipitously, according to an analysis of more than 20 years of U.S. cancer registry data.

The introduction of antiangiogenic agents is likely one key factor that led to the mortality decrease, said authors of the analysis of Surveillance, Epidemiology, and End Results data from 1992 to 2015.

Incidence trends are likely more complex and may reflect the interplay between increased detection, on one hand, and decreases in modifiable risk factors such as smoking on the other, the authors reported in Clinical Genitourinary Cancer.

The analysis, conducted by Anas M. Saad, a final-year medical student at Ain Shams University, Cairo; Thai H. Ho, MD, PhD, of Mayo Clinic Cancer Center, Phoenix; and coinvestigators, included a total of 104,584 patients with an RCC diagnosis, of whom nearly 64% were male and 80% were white. The majority of tumors were small and localized at diagnosis, and clear cell was the histologic subtype in 44%, according to the report.

Overall incidence of RCC was 11.3 per 100,000 person-years over the 1992-2015 study period, Dr. Saad and coauthors said in their report.

The incidence rate increased by about 2.4% per year, averaged over the course of the entire study period, though the plateau in rates began around 2008, according to the investigators. A figure in their report shows that the age-adjusted rate was just over 8 per 100,000 person-years in 1992; it climbed steadily until 2008, at which point it remained in the range of about 12-14 per 100,000 person-years for the next 7 years.

The uptick in incidence from 1992 to 2008 was concentrated mostly in localized and regional RCC, rather than distant disease, according to Dr. Saad and colleagues.

The overall incidence-based mortality rate for RCC was 5.3 per 100,000 person-years from 1992 to 2015, Dr. Saad and coauthors said.

Mortality rates increased from 1992 and peaked in 2001, at which point they started to drop at an ever accelerating pace. The annual percent decrease in that mortality rate was 1.5% between 2001 and 2008, 9.3% between 2008 and 2013, and 32.2% from 2013 to 2015, according to the report.

Incidence rate trends are probably affected by increases in incidental diagnoses and changes in RCC risk factor prevalence, investigators noted. For example, there has been a significant increase in use of advanced abdominal imaging, which has improved sensitivity in picking up renal masses, but cannot reliably distinguish between benign and malignant features, they said. On the other hand, smoking, which increases risk of RCC, has been trending downward for decades, which they said correlated with RCC trends.

Authors said RCC survival has been improved by antiangiogenic agents known as vascular endothelial growth factor inhibitors, and more recently immune checkpoint therapies, as clinical trials have shown.

“The decreasing mortality trend starting in 2007 and continuing until 2015 is associated with the introduction of such therapies for RCC treatment,” Dr. Saad and coauthors said in their report.

Support for the study came from the National Cancer Institute and the Department of Defense. Dr. Saad and coauthors declared that they had no conflicts of interest.

Among patients with stage III renal cell carcinoma (RCC) by current staging criteria, survival outcomes are worse for those who have pathological nodal involvement, results of a retrospective study suggest.

Survival was significantly shorter for stage III patients with nodal involvement versus those with no involvement, and was “equivalent” to survival in stage IV RCC patients, according to study author Jose A. Karam, MD, of the University of Texas MD Anderson Cancer Center, Houston, and his coauthors.

“If these findings are validated in other studies, consideration should be given to reclassifying patients with stage III, pN1 disease as having stage IV disease,” Dr. Karam and his coauthors wrote in Cancer.

Dr. Karam and his colleagues looked at records for patients with RCC of any histologic subtype who had undergone radical or partial nephrectomy between 1993 and 2012. Their analysis included a total of 389 patients with stage III disease, including 274 with node-positive disease (pT3N0M0) and 115 with node-negative disease (pT123N1M0), along with 523 patients who had stage IV disease.

They found that median overall survival was just 2.4 years (95% confidence interval, 1.7-4.1) for stage III, node-positive disease patients, compared with 10.2 years (95% CI, 8.7-not estimable [NE]) for stage III, node-negative disease and 2.4 years (95% CI, 2.1-3.0) for stage IV disease.

There was a significant difference in overall survival between the three groups, but no significant difference between patients with stage III node-positive disease and stage IV disease, the investigators wrote.

Similarly, median cancer-specific survival was 2.8 years (95% CI, 1.8-4.8) for stage III node-positive disease, not reached (95% CI, 10.2-NE) for stage III node-negative disease, and 2.4 years (95% CI, 2.1-3.0) for stage IV disease, the investigators wrote.

In multivariate analysis, pathological lymph node involvement in the stage III patients was independently associated with worse overall and cancer-specific survival.

Dr. Karam and his coauthors wrote that it may be prudent to revise the current staging system to reclassify node-positive patients if further research confirms their findings. By the current American Joint Committee on Cancer tumor, nodes, and metastases staging manual, patients can be classified as stage III on the basis of either primary tumor status (pT3) or pathological lymph node involvement, they said.

The incidence of pathological, node-positive disease in RCC ranges from 2%-10% in studies, with 5-year survival rates that are “poor” at 5%-30%, the authors noted in their report.

“Even in the targeted therapy era, adjuvant therapy with tyrosine kinase inhibitors does not appear to improve on these outcomes in patients with pN-positive disease,” they wrote.

Funding support for the research came from the National Institutes of Health/National Cancer Institute. Dr. Karam reported serving as a consultant/advisory board member for Pfizer, EMD Serono, Novartis, and Roche/Genentech, and that the MD Anderson Cancer Center has received clinical trial research funding from Roche/Genentech, though none of these disclosures were related to the current report.

A comparison of the genomic landscapes of both primary and metastatic clear cell renal cell carcinoma (ccRCC) found no significant differences in gene expression or mutational burden between the disease states, suggesting that there is no single genetic driver of metastases, investigators reported.

An analysis of targeted next-generation sequencing of both primary tumors and metastases in two independent patient cohorts showed that only the gene encoding for the tumor suppressor TP53 was significantly more frequently mutated in metastases, compared with primary tumors, but this finding did not pass a false positive test (false discovery rate), noted Toni K. Choueiri, MD, from the Dana-Farber Cancer Institute in Boston, and his colleagues, in the British Journal of Cancer.

“No other gene had significant difference in the cohort frequency of mutations between the metastases and primary tumors. Mutation burden was not significantly different between the metastases and primary tumors or between metastatic sites,” they wrote.

Frequently mutated genes in ccRCC include VHL, the gene encoding for von Hippel–Lindau syndrome, as well as tumor suppressor genes such as PBRM1, SEDT2, BAP1 and KDM5C, but few mutations are clinically actionable, the investigators noted. “However, the value of genomic alterations will be determined by understanding the interactions between acquired genetic alterations, treatments received, heterogeneity, and the dynamics of mutations during evolution of disease.”

To see whether they could improve understanding of the genomic differences between primary and metastatic ccRCC and potentially develop personalized therapies, the investigators studied targeted next-generation sequencing data from two separate cohorts.

The first cohort included data on 349 ccRCC primary tumors and 229 unmatched cases of metastatic ccRCC from the Foundation Medicine database. The second, a validation cohort, included data on 177 ccRCC primary tumors and 80 metastases from patients treated at Dana-Farber. In each cohort, sequencing was performed on 275 genes and intronic regions in 30 genes for a total of 282 unique genes.

In cohort 1, which included tumor samples from 417 men and 169 women with a median age of 58 years, the frequency of mutations was similar in primary tumors and metastases. As noted before, mutations in TP53 were significantly more frequent in metastases than in primary tumors, detected in 14.85% versus 8.90% of samples, respectively (P = .031). This difference did not, however, pass the false discovery rate test (q = 0.21). Two other tumor suppressor genes, PBRM1 and KDM5C, were numerically but not significantly more frequent in metastases.

There were no differences in median tumor mutational burden between primary and metastatic samples and no difference in either mutations or mutational burden across different metastatic sites.

In cohort 2 there were no significantly different mutational frequencies between primary and metastatic samples for any gene and no differences in median tumor mutational burden.

An analysis comparing the frequency of gene mutations in primary tumors of patients in this cohort who went on to develop metastatic disease versus those of patients with only localized disease showed that, after a median follow-up of 21.9 months, there were no significant differences in either mutational frequency or tumor mutational burden.

“It is currently unknown if cohortwide genomic alterations in RCC metastases have a different genomic profile, including potential actionable mutations, compared to samples derived from the primary site. To our knowledge, our analysis is the largest genomic ccRCC study that compares cohortwide mutational differences between metastases and primary tumors,” the investigators wrote.

They acknowledged that because they did not match primary tumors with metastatic tumors in the same patients they were unable to evaluate how individual tumors evolve over time or how systemic therapies may alter the tumor genomic landscape.

An updated analysis of interim results for JAVELIN Renal 101 will be presented at a Presidential Symposium during the annual congress of the European Society for Medical Oncology (ESMO 2018), to be held Oct. 19-23 in Munich.

The phase 3 trial compared avelumab (Bavencio) in combination with axitinib (Inlyta) to sunitinib monotherapy as first-line treatment, in patients with advanced renal cell carcinoma (RCC). Interim analysis results announced by the company in a September press release indicated the combination of immunotherapy and a tyrosine kinase inhibitor showed “a statistically significant improvement in progression-free survival by central review for patients treated with the combination whose tumors had programmed death ligand-1‒positive (PD-L1+) expression greater than 1% (primary objective), as well as in the entire study population regardless of PD-L1 tumor expression (secondary objective).”

An updated analysis of progression-free survival and overall response rates will be presented at ESMO 2018 by Robert J. Motzer, MD of Memorial Sloan Kettering Cancer Center, New York.

A phase 1b study (JAVELIN Renal 100), published in Lancet Oncology, found the safety profile of the combination to be similar to either drug alone.

For the phase 3 trial, more than 800 patients with advanced RCC were randomized to first-line treatment with the combination of avelumab (10 mg/kg IV every 2 weeks) plus axitinib (5 mg orally, twice daily) or monotherapy with sunitinib (50 mg orally once daily, 4 weeks on/2 weeks off). The overall survival results will be presented at the Presidential Symposium 2 on Oct. 21.

This article was updated on 10/15/18 to reflect the fact that interim results will be presented.
