RESUMO

BACKGROUND: Combined treatment with BRAFi and/or MEK inhibitors (MEKi) improves outcomes in advanced melanoma patients in comparison with monotherapy. OBJECTIVE: We aim to report real-world treatment efficacy and safety of vemurafenib (V) and vemurafenib + cobimetinib (V + C) from 10 years of practice. PATIENTS AND METHODS: A total of 275 consecutive patients with unresectable or metastatic BRAF mutated melanoma started first-line V or V + C treatment between 1 October 2013 and 31 December 2020. Survival analyses were performed using the Kaplan-Meier method, and Log-rank and Chi-square tests were used for comparison between groups. RESULTS: The estimated median overall survival (mOS) was 10.3 months in the V group, and 12.3 months in the V + C group (p = 0.0005; HR = 1.58, 95% CI 1.2-2.1), although the latter group of patients had lactate dehydrogenase elevated numerically more often. Estimated median progression-free survival (mPFS) was 5.5 months in the V group, and 8.3 months in the V + C group (p = 0.0002; HR = 1.62, 95% CI 1.3-2.1). Complete response, partial response, stable disease, and progressive disease as best responses were recorded in the V/V + C groups in 7%/10%, 52%/46%, 26%/28%, and 15%/16% of patients, respectively. The numbers of patients with any grade of adverse effects were similar in both groups. CONCLUSIONS: We confirmed significant improvement in the mOS and mPFS of unresectable and/or metastatic BRAF mutated-melanoma patients treated outside clinical trials with V + C as compared with V, with no major increase in toxicity for the combination.

RESUMO

BACKGROUND: On 24th of February 2022, Ukrainian cancer patients had to face a new war. Here we describe an experience of the Maria Sklodowska-Curie National Research Institute of Oncology Branch Krakow in providing cancer care for Ukrainian refugees during the initial 6 weeks of war. We present patients' characteristic, point out the main challenges and share initiatives undertaken. MATERIALS AND METHODS: For this cross-sectional analysis, we have gathered demographic and clinical data together with date of crossing the Polish-Ukrainian border for 112 Ukrainian refugees with cancer who had their first-time oncology consultation between 24th February and 8th April 2022. We have also implemented national guidelines and created local procedures, interventions and policies to manage this situation. RESULTS: The peak of patient inflow was the third week of War and refugees accounted for 13% of all first-time patients within that period of time. The majority of refugees were women (86%), treated radically (57%) with breast cancer (43%). Most of the patients required systemic treatment (67%). Amongst the main challenges at the time were differences in the reimbursement system, communication issues, lack of patients' documentation or tissue samples, prolonged diagnostic or treatment interruptions, increased risk of COVID-19 infections, chemotherapy side effects, and lack of procedures. Legal, procedural and organizational steps implemented at the local and national level were described. CONCLUSIONS: The Russian invasion on Ukraine forced an unexpectedly high number of Ukrainian cancer patients to seek help abroad, leading to the straining of the health care system in Poland.
