Lack of survival gain for elderly women with breast cancer.

ABSTRACT: BACKGROUND: The number of elderly women with breast cancer is increasing and will become a major health concern. However, little is known about the optimal treatment for this age group. The aim of this study was to describe time trends for the overall Dutch breast cancer cohort with an emphasis on differences between young and elderly patients. METHODS: All adult female patients diagnosed in 1995-2005 were selected from the Netherlands Cancer Registry. Relative excess risks for death (adjusted for stage, histology, treatment, and grade) were estimated using a multivariate generalized linear model with a Poisson distribution, based on collapsed relative survival data, using exact survival times. RESULTS: Overall, 127,805 patients were included. Treatment of patients aged ?75 years changed significantly over time: they received less surgery, more adjuvant hormonal treatment and chemotherapy, and more hormonal treatment without surgery. In contrast to younger patients, the relative survival did not improve significantly over time for elderly patients. With increasing age, the observed-expected death ratio decreased to almost 1.0. CONCLUSION: Survival for elderly patients with breast cancer did not improve significantly. Observed-expected death ratios in the elderly are close to 1, indicating that excess mortality is low. Elderly patients with breast cancer have a higher risk for overtreatment and undertreatment, with a delicate therapeutic balance between breast cancer survival gain and potential toxicities. To improve breast cancer survival in the elderly, a critical reappraisal is needed of costs and benefits of hormonal as well as other treatments, and better selection of patients who can benefit from available therapies is warranted.

Project description:Background and aimsIn recent years, the best treatment method for pancreatic cancer in elderly patients has remained controversial. Surgery is the main treatment modality for pancreatic cancer. This study aimed to determine whether elderly patients with pancreatic cancer can gain survival advantages through more active and radical surgical treatment and evaluate the best treatment method and potential prognostic factors.MethodsFrom the Surveillance, Epidemiology, and End Results program (SEER) database, 10,557 elderly patients (aged ≥65 years) with pancreatic cancer were included as Cohort 1, and Propensity Score Matching (PSM) evaluation was performed to generate Cohort 2 (424 pairs). Overall Survival (OS) and Cause-Specific Survival (CSS) were determined using Kaplan-Meier survival curves, and differences were assessed using the Log-rank test. Multivariate logistic regression analysis and the forest plot of hazard ratio (HR) was made to assess the association between potential prognostic factors, including surgery and different surgical methods, and survival in elderly patients.ResultsWe identified 10,557 eligible patients with pancreatic cancer, who formed Cohort 1. The total OS and CSS in the surgery group were significantly higher than those in the non-surgery group (P < 0.001). Age, stage (AJCC 8th), grade, lymph node metastasis, radiation, chemotherapy, and surgical methods were independent factors affecting the prognosis of elderly patients. In Cohort 2, Total pancreatectomy (Total PT) had the lowest risk ratio (HR = 0.31, P < 0.001) and longest median CSS (18.000 months), while Extension Total pancreatectomy (Ex-Total PT, HR = 0.34, P < 0.001) showed the lower median CSS (17.000 months) and median OS (14.000 months). Partial pancreatectomy (Partial PT, HR = 0.46, P < 0.001) showed the lowest median CSS (13.000 months) and median OS (12.000 months), although they were still higher than the median CSS (6.000 months) and median OS (5.000 months) in the non-surgery group.ConclusionsBased on the SEER database, surgical treatment is an independent prognostic factor in elderly patients with pancreatic cancer. Compared with other surgical methods, Total PT can offer elderly patients the best survival advantages. However, Ex-Total PT, a more radical method, does not seem to be the best treatment option for the survival and benefit of elderly patients.
