Men with low-risk prostate cancer who go on active surveillance rather than treatment are best followed-up for more than 15 years — and perhaps indefinitely — according one of the longest studies to date to look at the issue. 

Previous studies have shown that active surveillance continued for 15 years is appropriate to identify men who progress and need treatment, but now data out to 25 years “suggest that meticulous follow-up is needed over a longer time if the chance for cure is not to be missed,” said Emmeli Palmstedt, PhD, a research student in the Department of Urology at the Sahlgrenska Academy at the University of Gothenburg, Sweden. “These data are crucial, given the long current life expectancy” of men in otherwise good health. 

Dr. Palmstedt presented the findings at the 2024 annual meeting of the European Association of Urology.

At many centers, active surveillance is a standard of care for men with low-risk prostate cancer based on a benefit-to-risk ratio that favors delayed intervention, according to Palmstedt. Several studies, including the Göteburg-1 active surveillance trial initiated at her institution, have supported follow-up for 15 years. A new set of data from Göteborg now extends to 25 years.
 

Long-Life Expectancy Justifies Extended Surveillance

The prospective Göteborg study began enrolling men with very low- or low-risk (78%) or intermediate-risk (22%) prostate cancer in 1995. In the active surveillance program, prostate-specific antigen (PSA) was measured routinely with biopsies ordered for PSA levels ≥ 2.5 ng/mL. 

In an analysis published in 2016 when 202 (43%) of 474 patients managed with active surveillance had discontinued surveillance to start treatment, the median follow-up period was 8 years. The rate of mortality associated with prostate cancer at 15 years was estimated to be 0% for men in the very low-risk group, 4% for men in the low-risk group, and 10% for those with intermediate-risk tumors. The estimates for failure-free survival at 15 years were 88%, 77%, and 40% for the very low-, low-, and intermediate-risk groups, respectively.

In the most recent follow-up, when the median age in the Göteburg-1 study was 80 years (the median age at diagnosis was 66 years), the median follow-up period was 15.1 years with a range of up to 28.1 years. In this analysis, which focused on patients with low-risk prostate cancer at baseline, discontinuations from active surveillance had climbed to 47%. Most of these men discontinued to initiate treatment, but 79 (16%) had failed acute surveillance, meaning their progression was not caught in time for curative-intent treatment, and 2% had died from prostate cancer.
 

Treatment-Free Survival Falls to 31% 

The rate of treatment-free survival, which was estimated to be 65% in the 15-year analysis published in 2016, had declined to 31%. The rate of failure-free survival was 59%, and prostate cancer-specific survival was 92%, according to the researchers. 

While Dr. Palmstedt did not separate out her data for very low- and low-risk patients, she noted that deaths from prostate cancer among all low-risk patients climbed fourfold (8% vs 2%) since the 2016 figures were published. The proportion of men no longer failure-free climbed from 10% to more than 40%. 

“These are non-negligible numbers,” said Dr. Palmstedt, who added that overall survival fell from 69% at 15 years to 37% at 25 years.

Although some men between the 15-year and 25-year timepoints were switched to watchful waiting, these data have not yet been analyzed.

The low rate of deaths from prostate cancer over the extended period is reassuring, Dr. Palmstedt said, but the main message from the new study is that active surveillance permits curative-intent treatment to be offered even after late follow-up. She emphasized that patients without progression by 15 years cannot be considered “safe.”

Based on these data, “men with a long remaining life expectancy should be informed that active surveillance is still viable after 15 years,” Dr. Palmstedt said.
 

Active Surveillance Now More Common

Over the past decade, the proportion of men with prostate cancer managed with active surveillance has been rising steadily, according to Matthew R. Cooperberg, MD, MPH, professor of urology at the University of California, San Francisco. In a study published last year in JAMA Network Open, Dr. Cooperberg and his colleagues reported that rates of active surveillance rose from 26.5% in 2014 to 59.6% in 2021. However, given the value of the approach for avoiding overtreatment of men with low-risk prostate cancers, even that increase is not enough, he said.

“The window of opportunity for cure is typically very wide,” Dr. Cooperberg said. Although many men “will never need treatment ... long-term surveillance is definitely important” for those that do, he said. The data from trials like Göteborg-1 support the principle that this strategy still preserves the option of treatment when it is needed. 

“Treatment for cure at age 70 is generally far preferable to treatment at 55, and surveillance should absolutely be preferred treatment for the vast majority of men with low-grade disease at diagnosis,” he explained.

Dr. Palmstedt reported no potential conflicts of interest. Dr. Cooperberg reported financial relationships with Astellas, AstraZeneca, Bayer, Dendreon, Exact Sciences, Janssen, Merck, Pfizer, and Verana Health.

How long should a woman wait before becoming pregnant again? According to the World Health Organization (WHO), it is advisable to wait at least 24 months between childbirth and a new pregnancy. But a study published in February of this year in The Lancet Regional Health — Americas, using data from more than 4.7 million live births in Brazil, suggests that this recommendation should be individualized, considering factors such as maternal obstetric history.

Researchers from the Federal University of Grande Dourados (UFGD), Oswaldo Cruz Foundation, São José do Rio Preto Medical School, Federal University of Bahia, and the London School of Hygiene and Tropical Medicine in the United Kingdom, used a birth cohort from the Center for Data Integration and Knowledge for Health, which combines data from the Ministry of Health’s Information System on Live Births (SINASC) and from a cohort of 100 million Brazilians. 

In total, the analysis included information on 3,804,152 women and 4,788,279 births. All participants had at least two consecutive live births.

Most interpregnancy intervals, ie, the difference between the previous childbirth and the subsequent conception, ranged from 23 to 58 months (39.1%). Extreme intervals of < 6 months and > 120 months occurred in 5.6% and 1.6% of cases, respectively.

Regarding adverse outcomes, the research indicated that, in the general population, small-for-gestational-age (SGA) babies were observed in 8.4% of subsequent births, while low birth weight (LBW) occurred in 5.9% and preterm birth in 7.5%.
 

Interpregnancy Interval and SGA Risk

The authors noted that the risk for subsequent adverse outcomes increased with extreme interpregnancy intervals, with SGA being the only exception. In this case, women who had an interval between the previous childbirth and the subsequent conception > 120 months had a lower risk for SGA.

According to João Guilherme Tedde, a medical student at UFGD and the first author of the study, similar patterns (extremely long interpregnancy intervals associated with a lower risk for subsequent SGA) have been described in the literature. In an interview with this news organization, he explained some hypotheses that could explain this phenomenon.

According to the researcher, the finding may reflect the distinct risk profile of mothers who wait a very long time to conceive again. “This group, composed of older women, likely has a higher prevalence of health problems, such as diabetes and obesity, which are known risk factors for having large-for-gestational-age (LGA) babies,” he said. He also highlighted the fact that the study showed that the risk for LGA also increased as the interval between pregnancies grew.

Another hypothesis suggested by the author is the possible occurrence of events between pregnancies, such as miscarriages or stillbirths. According to him, women who have experienced these events between two consecutive pregnancies may have falsely increased interpregnancy intervals, since miscarriages and stillbirths (which are considered conceptions) are not counted in SINASC.

“Thus, the lower occurrence of SGA in the group with very long intervals may reflect a competition of events between stillbirths or miscarriages and live SGAs,” he said.
 

Previous and Subsequent Adverse Events

The research also showed that the risks for subsequent SGA, LBW, and preterm birth were higher among women with a history of adverse events in previous pregnancies.

Furthermore, the authors noted that the previous occurrence of adverse outcomes seems to “have a more significant impact on the outcome of the current pregnancy than the interpregnancy interval.” 

“We found that, for women with the same interpregnancy interval (say < 6 months), but with different obstetric history (zero previous events vs one event), the absolute risk for subsequent adverse outcomes increased much more than when we change only the duration of the interval in a group with the same number of previous adverse events,” said Dr. Tedde.

There is still no convincing explanation for this fact, he said, since the cause-and-effect relationship between interpregnancy intervals and perinatal events is not clear. But the obstetrics literature generally shows that among the main risk factors for an adverse event is the previous occurrence of the same event. This effect could be related to living conditions and maternal habits, genetics, epigenetics, among others.

The researcher observed that this study is one of the largest in terms of sampling to investigate how maternal obstetric history can modulate the effect of interpregnancy interval on the risk for adverse outcomes in subsequent pregnancies.

The findings of the research published this year reinforce the importance of individualizing recommendations regarding interpregnancy intervals, considering factors such as maternal obstetric history. However, the author warns that it is still too early to point out the “best” interval for each situation.

“We need more studies that reproduce our findings and that expand the analyzed outcomes to also include those of interest to the mother, such as maternal mortality,” he concluded.

Key clinical point: Anti-calcitonin gene-related peptide monoclonal antibodies (anti-CGRP mAb) showed superior efficacy to botulinum toxin A (BoNT-A) in reducing the migraine burden in patients with chronic migraine (CM).

Major finding: Anti-CGRP mAbs vs BoNT-A led to significant reductions in mean Headache Impact Test-6 and Allodynia Symptoms Checklist-12 scores at 6 months (mean change −11.1 vs −3.2 points, P < .0001; and −5.2 vs −0.5 points, P = .0056, respectively) and 12 months (mean change −11.4 vs −3.6 points, P = .0042; and −6.0 vs −0.9 points, P = .0011, respectively).

Study details: This exploratory analysis of the real-world effectiveness of anti-CGRP mAb vs BoNT-A included 126 patients with CM who were treated with anti-CGRP mAb (n = 36) or BoNT-A (n = 90).

Disclosures: The study was supported by the Italian Ministry of Health. Some authors declared receiving funding, travel grants, honoraria, or personal fees for participation in advisory boards, speaker panels, and clinical investigation studies from various sources.

Key clinical point: Treatment with a combination of anti-calcitonin gene-related peptide (anti-CGRP) monoclonal antibodies (mAb) and onabotulinumtoxinA (onabot) was more effective than monotherapy with either anti-CGRP alone or onabot in reducing monthly migraine days (MMD) in patients with chronic migraine.

Major finding: Initiating therapy with either anti-CGRP mAbs or onabot significantly reduced the median MMD from 30 to 15 days, which further decreased to 8 days after initiating dual therapy with anti-CGRP mAb and onabot (both P < .0001). Overall, 68% of patients receiving dual therapy achieved 50% or greater reduction in MMD.

Study details: This real-world retrospective chart review included 423 patients with chronic migraine (age ≥ 18 years) who received monotherapy with either anti-CGRP mAb or onabot (n = 229) followed by dual therapy (concurrent treatment with anti-CGRP mAb and onabot; n = 194) for at least three consecutive months.
