Women With Cancer Show Improved Survival But Higher Risk of Severe Side Effects

Female cancer patients have increased survival but also have a higher risk for serious and adverse side effects from cancer treatment compared with men, according to a study published online in the Journal of the National Cancer Institute. Researchers examined the association between patient sex and overall survival, progression-free survival, and grade ≥3 adverse events in a pooled individual participant data meta-analysis involving 20,806 participants from 39 phase 2 to 3 trials supporting U.S. Food and Drug Administration approvals of anticancer medicines for advanced solid tumors.

The researchers found that female sex was associated with significantly improved overall survival and progression-free survival in trials across 12 tumor types. However, women also had increased risk for grade ≥3 adverse events. "If women are living longer but experiencing more severe side effects, we need to acknowledge that and respond to it," the lead author said in a statement. "At the same time, we need to better understand why male patients appear to have poorer survival."

In related research, healthful nutrition may represent an underused, modifiable strategy to support fertility in female cancer survivors, a population at heightened risk of infertility, but practical implementation is limited by time pressures, absent guidelines, and inconsistent counseling. Qualitative findings suggest that while clinicians acknowledge potential benefits cautiously, survivors are motivated to change dietary behaviors if clear, credible recommendations are provided.

Time constraints emerged as a dominant barrier for both clinicians and survivors. Providers reported that limited visit durations required prioritization of immediate medical concerns, leaving insufficient opportunity for detailed nutrition counseling. A second major barrier was the absence of standardized, evidence-based fertility nutrition guidelines. Clinicians cited a perceived lack of robust research and limited nutrition education within medical training, restricting their ability to offer specific recommendations.

Despite these barriers, perspectives diverged on perceived impact. Many clinicians expressed skepticism about the magnitude of nutrition's effect on fertility outcomes, whereas survivors consistently reported strong motivation to adopt dietary changes if doing so might improve reproductive success or future child health. "Improving female cancer survivor fertility outcomes will require the development of standardized fertility nutrition guidelines, the integration of nutrition support into oncofertility treatment, and prioritizing funding for fertility-related nutrition research with a focus on the female cancer survivor population," said the authors.

Specialized cancer nurses provide an important sense of stability by proactively checking in with patients and providing clear information about care and support services. Ensuring continuity in nursing relationships is key to building trust and reducing patient's emotional distress with the experience of having a cancer that is often complicated by stigma.
