Mesothelioma is a rare and aggressive tumour with dismal prognosis arising in the pleura and associated with asbestos exposure. Its incidence is on the rise worldwide. In selected patients with early-stage MPM, a maximal surgical cytoreduction in combination with additional antitumour treatment may be considered in selected patients assessed by a multidisciplinary tumor board. In patients with unresectable or advanced MPM, chemotherapy with platinum plus pemetrexed is the standard of care. Currently, no standard salvage therapy has been approved yet, but second-line chemotherapy with vinorelbine or gemcitabine is commonly used. Novel therapeutic approaches based on dual immunotherapy or chemotherapy plus immunotherapy demonstrated promising survival benefit and will probably be incorporated in the future.

To complement the existing treatment guidelines for all tumour types, ESMO organises consensus conferences to focus on specific issues in each type of tumour. The 2nd ESMO Consensus Conference on Lung Cancer was held on 11-12 May 2013 in Lugano. A total of 35 experts met to address several questions on non-small-cell lung cancer (NSCLC) in each of four areas: pathology and molecular biomarkers, first-line/second and further lines of treatment in advanced disease, early-stage disease and locally advanced disease. For each question, recommendations were made including reference to the grade of recommendation and level of evidence. This consensus paper focuses on locally advanced disease.

Compared with treatment options for early-stage breast cancer, few data exist regarding the optimal use of chemotherapy for metastatic breast cancer (MBC). The choice of using a combination of cytotoxic chemotherapies vs sequential single agents is controversial. At the 6th European Breast Cancer Conference, the European School of Oncology Metastatic Breast Cancer Task Force convened an open debate on the relative benefits of combination vs sequential therapy. Based on the available data, the Task Force recommends sequential monotherapy as the preferred choice in advanced disease, in the absence of rapid clinical progression, life-threatening visceral metastases, or the need for rapid symptom and/or disease control. Patient- and disease-related factors should be used to choose between combination and sequential single-agent chemotherapy for MBC. Additional research is needed to determine the impact of therapy on patient-rated quality of life and to identify predictive factors that can be used to guide therapy.

BACKGROUND: Cancer Care Ontario\'s (CCO) Program in Evidence-based Care has provided a credible basis for policy development and the funding of new and expensive anticancer drugs in the province of Ontario. In November 1997, vinorelbine was approved for the first-line treatment of advanced non-small cell lung cancer (NSCLC) on the basis of evidence-based practice guidelines generated by the Provincial Lung Disease Site Group. In June 1998, gemcitabine was approved as an alternative to vinorelbine for use in selected patients (e.g. significant venous access problems, peripheral neuropathy, severe toxicity to vinorelbine). A provincial drug database was used to determine the impact that these new policies had on the rate of vinorelbine and gemcitabine uptake within the CCO new drug funding programme.
METHODS: Drug utilization data for vinorelbine and gemcitabine from October 1997 to June 1999 were obtained from the CCO drug database. Individual patient data consisted of age, gender, first-line agent used, number of treatments, duration of therapy, treatment location (regional cancer centre vs. other) and total cost. Demographic and drug utilization data were analysed descriptively as means, medians, or proportions. Multivariable logistic regression analysis was then used to identify factors associated with the selection of gemcitabine over vinorelbine, as a first-line therapy.
RESULTS: Following the approval of the first policy in November 1997, there was a rapid adoption of vinorelbine use in new NSCLC patients. When the gemcitabine policy was approved in June 1998, there was a rapid uptake in its use reaching a stable plateau of approximately 15% of all NSCLC patients within 9 months. The logistic regression analysis identified patient age greater than 65 years [odds ratio (OR) = 1.90, P = 0.001] and treatment in a non-regional cancer setting (OR = 1.71, P = 0.008) as significant predictors of gemcitabine utilization. Overall, the mean drug cost per patient treated with first-line gemcitabine was significantly higher than vinorelbine (Can 2590 dollars vs. Can 1030 dollars, P < 0.001).
CONCLUSIONS: The new funding policies were associated with a rapid increase in drug utilization reaching a stable plateau within 9 months. Factors contributing to the usage of these new drugs for NSCLC included patient characteristics, such as age and treatment location.
