Burden of early, advanced and metastatic breast cancer in The Netherlands.

BACKGROUND: The aim of this study was to estimate the total economic and health related burden of breast cancer in the Netherlands. METHODS: Data on incidence, prevalence, mortality and survival were extracted from the Dutch National Cancer Registry and were used to calculate the economic and health related burden of breast cancer for overall, DCIS (stage 0), early- (stage I), locally advanced- (stage II-III) and metastatic- (stage IV) breast cancer by age groups and by year (if applicable). RESULTS: The overall incidence of breast cancer increased from 103.4 up to 153.2 per 100,000 women between 1990 and 2014. The increase was driven by DCIS and early breast cancer as the incidence of locally advanced and metastatic breast cancer remained stable. Between 1990 and 2014, ten-year overall survival rates increased from 87% to 93% for early breast cancer, 41% to 62% for locally advanced- and from 6% to 9% for metastatic disease. Annually, breast cancer in the Netherlands is responsible for approximately 3100 deaths, 26,000 life years lost, 65,000 Disability Adjusted Life Years (DALYs) and an economic burden of €1.27 billion. CONCLUSIONS: This study provides a comprehensive assessment of the burden of breast cancer and subsequent trends over time in the Netherlands.

Prediction of treatment-related toxicity and outcome with geriatric assessment in elderly patients with solid malignancies treated with chemotherapy: a systematic review.

INTRODUCTION: The number of older patients with cancer is increasing. Standard clinical evaluation of these patients may not be sufficient to determine individual treatment strategies and therefore Geriatric Assessment (GA) may be of clinical value. In this review, we summarize current literature that is available on GA in elderly patients with solid malignancies who receive chemotherapy. We focus on prediction of treatment toxicity, mortality and the role of GA in the decision-making process. DESIGN: We conducted a systematic search in PubMed. Studied populations needed to fulfill the following criteria: 65 years or older, diagnosis of solid malignancy, treatment with chemotherapy, submission to GA, either designed to study prediction of treatment toxicity or mortality or to evaluate the role of GA in the decision-making process. RESULTS: Our search provided 411 publications. Thirteen met the predefined criteria. These studies revealed: (i) up to 64% of elderly patients suffer from severe toxicity caused by polychemotherapy, (ii) Nutritional status, functionality and comorbidity are often associated with worse outcome, (iii) GA reveals (unknown) geriatric problems in more than 50% of elderly patients with cancer and (iv) 21%-53% of chemotherapy regimens are being modified based on GA. CONCLUSIONS: In geriatric oncology, an accurate predictive test to guide anticancer treatment in order to prevent serious toxicity is needed. The value of GA in predicting toxicity and mortality in older patients with cancer undergoing treatment with chemotherapy has not been proven. It may be valuable in revealing geriatric problems but current evidence for its usefulness to guide treatment decisions in this setting is limited. However, we are convinced that GAs should be carried out to optimize treatment strategies in elderly patients with cancer to improve treatment efficacy and minimize toxicity.
