Clinical trials in elderly ovarian cancer patients - does it make sense?

Ovarian cancer in the older patient: where are we now? What to do next?

In recent years, major advances have been made toward the individualization of epithelial ovarian cancer care, leading to an overall improvement of patient outcomes. However, real-life data indicate that the oldest populations do not benefit from this, due to aspects related to cancer (more aggressive histopathological features), treatment (i.e. frequently suboptimal), and the host (increased toxicities in patients with lower physiological reserve). A specific risk-benefit perspective should therefore be taken when considering surgery, chemotherapy, and maintenance treatments: the decision for cytoreductive surgery should include geriatric vulnerability and surgical complexity, neo-adjuvant chemotherapy being an option when primary surgery appears at high risk; carboplatin paclitaxel association remains the standard even in vulnerable older patients; and bevacizumab and poly(ADP-ribose) polymerase inhibitors maintenance are interesting options provided they are prescribed according to their indications with a close monitoring of their toxicities. Future studies should aim to individualize care without limiting access of older patients to innovation. A specific focus is needed on age-specific translational analyses (focusing on tumor mutational burden and impaired biological pathways), a better patient stratification according to geriatric parameters, an adaptation of both oncological treatment and geriatric interventions, and treatment adaptations not a priori but according to formal pharmacokinetic data.

Management and Survival of Elderly and Very Elderly Patients with Ovarian Cancer: An Age-Stratified Study of 1123 Women from the FRANCOGYN Group

Elderly women with ovarian cancer are often undertreated due to a perception of frailty. We aimed to evaluate the management of young, elderly and very elderly patients and its impact on survival in a retrospective multicenter study of women with ovarian cancer between 2007 to 2015. We included 979 women: 615 women (62.8%) <65 years, 225 (22.6%) 65–74 years, and 139 (14.2%) ≥75 years. Women in the 65–74 years age group were more likely to have serous ovarian cancer (p = 0.048). Patients >65 years had more >IIa FIGO stage: 76% for <65 years, 84% for 65–74 years and 80% for ≥75 years (p = 0.033). Women ≥75 years had less standard procedures (40% (34/84) vs. 59% (104/177) for 65–74 years and 72% (384/530) for <65 years (p < 0.001). Only 9% (13/139) of women ≥75 years had an Aletti score >8 compared with 16% and 22% for the other groups (p < 0.001). More residual disease was found in the two older groups (30%, respectively) than the younger group (20%) (p < 0.05). Women ≥75 years had fewer neoadjuvant/adjuvant cycles than the young and elderly women: 23% ≥75 years received <6 cycles vs. 10% (p = 0.003). Univariate analysis for 3-year Overall Survival showed that age >65 years, FIGO III (HR = 3.702, 95%CI: 2.30–5.95) and IV (HR = 6.318, 95%CI: 3.70–10.77) (p < 0.001), residual disease (HR = 3.226, 95%CI: 2.51–4.15; p < 0.001) and lymph node metastasis (HR = 2.81, 95%CI: 1.91–4.12; p < 0.001) were associated with lower OS. Women >65 years are more likely to have incomplete surgery and more residual disease despite more advanced ovarian cancer. These elements are prognostic factors for women’s survival regardless of age. Specific trials in the elderly would produce evidence-based medicine and guidelines for ovarian cancer management in this population.
