Update of survival and cost of metastatic melanoma with new drugs: Estimations from the MelBase cohort.

PURPOSE: Since 2011, significant progress was observed in metastatic melanoma (MM), with the commercialisation of seven immunotherapies or targeted therapies, which showed significant improvement in survival. In France, in 2004, the cost of MM was estimated at €1634 per patient; this cost has not been re-estimated since. This study provided an update on survival and cost in real-life clinical practice. METHODS: Clinical and economic data (treatments, hospitalisations, radiotherapy sessions, visits, imaging and biological exams) were extracted from the prospective MelBase cohort, collecting individual data in 955 patients in 26 hospitals, from diagnosis of metastatic disease until death. Survival was estimated by the Kaplan-Meier method. Costs were calculated from the health insurance perspective using French tariffs. For live patients, survival and costs were extrapolated using a multistate model, describing the 5-year course of the disease according to patient prognostic factors and number of treatment lines. RESULTS: Since the availability of new drugs, the mean survival time of MM patients has increased to 23.6 months (95%confidence interval [CI] :21.2;26.6), with 58% of patients receiving a second line of treatment. Mean management costs increased to €269,682 (95%CI:244,196;304,916) per patient. Drugs accounted for 80% of the total cost. CONCLUSION: This study is the first that evaluated the impact of immunotherapies and targeted therapies both on survival and cost in real-life conditions. Alongside the introduction of breakthrough therapies in the first and subsequent lines, MM has been associated with a significant increase in survival but also in costs, raising the question of financial sustainability.

Exploring disparities in incidence and mortality rates of breast and gynecologic cancers according to the Human Development Index in the Pan-American region.

OBJECTIVE: To evaluate whether a country's Human Development Index (HDI) can help explain the differences in the country's breast cancer and gynecological cancer incidence and mortality rates in the Pan-American region. STUDY DESIGN: Ecological analysis. METHODS: Pan-American region countries with publicly available data both in GLOBOCAN 2012 and the United Nations Development Report 2012 were included (n = 28). Incidence and mortality rates age-standardized per 100,000 were natural log-transformed for breast cancer, ovarian cancer, corpus uteri cancer, and cervical cancer. The mortality-to-incidence ratio (MIR) was calculated for each site. Pearson's correlation test and a simple linear regression were performed. RESULTS: The HDI showed a positive correlation with breast cancer and ovarian cancer incidence and mortality rates, respectively, and a negative correlation with cervical cancer incidence and mortality rates. The HDI and corpus uteri cancer showed no association. MIR and the HDI showed a negative correlation for all tumor types except ovarian cancer. An increment in 1 HDI unit leads to changes in cancer rates: in breast cancer incidence ß = 4.03 (95% confidence interval [CI] 2.61; 5.45) P < 0.001, breast cancer mortality ß = 1.76 (95% CI 0.32; 3.21) P = 0.019, and breast cancer-MIR ß = -0.705 (95% CI 0.704; 0.706) P < 0.001; in cervical cancer incidence ß = -3.28 (95% CI -4.78; -1.78) P < 0.001, cervical cancer mortality ß = -4.63 (95% CI -6.10; -3.17) P < 0.001, and cervical cancer-MIR ß = -1.35 (95% CI -1.83; -0.87) P < 0.001; in ovarian cancer incidence ß = 3.26 (95% CI 1.78; 4.75) P < 0.001, ovarian cancer mortality ß = 1.82 (95% CI 0.44; 3.20) P = 0.012, and ovarian cancer-MIR ß = 5.10 (95% CI 3.22; 6.97) P < 0.001; in corpus uteri cancer incidence ß = 2.37 (95% CI -0.33; 5.06) P = 0.83, corpus uteri cancer mortality ß = 0.68 (95% CI -2.68; 2.82) P = 0.96, and corpus uteri cancer-MIR ß = -2.30 (95% CI -3.19; -1.40) P < 0.001. CONCLUSIONS: A country's HDI should be considered to understand disparities in breast cancer and gynecological cancer in the Pan-American region.

Guidelines for time-to-event end point definitions in breast cancer trials: results of the DATECAN initiative (Definition for the Assessment of Time-to-event Endpoints in CANcer trials)†.

BACKGROUND: Using surrogate end points for overall survival, such as disease-free survival, is increasingly common in randomized controlled trials. However, the definitions of several of these time-to-event (TTE) end points are imprecisely which limits interpretation and cross-trial comparisons. The estimation of treatment effects may be directly affected by the definitions of end points. The DATECAN initiative (Definition for the Assessment of Time-to-event Endpoints in CANcer trials) aims to provide recommendations for definitions of TTE end points. We report guidelines for randomized cancer clinical trials (RCTs) in breast cancer. PATIENTS AND METHODS: A literature review was carried out to identify TTE end points (primary or secondary) reported in publications of randomized trials or guidelines. An international multidisciplinary panel of experts proposed recommendations for the definitions of these end points based on a validated consensus method that formalize the degree of agreement among experts. RESULTS: Recommended guidelines for the definitions of TTE end points commonly used in RCTs for breast cancer are provided for non-metastatic and metastatic settings. CONCLUSION: The use of standardized definitions should facilitate comparisons of trial results and improve the quality of trial design and reporting. These guidelines could be of particular interest to those involved in the design, conducting, reporting, or assessment of RCT.
