Extended duration of anti-PD-1 therapy, using reduced frequency dosing, in patients with advanced melanoma and Merkel cell carcinoma
How long an MCC patient should continue to receive immunotherapy treatment is unclear. This study aimed to investigate whether reduced frequency dosing (giving immunotherapy less often) is effective in preventing the cancer from coming back, while also lowering patient costs and increasing convenien...
Delayed time to radiation and overall survival in Merkel cell carcinoma
MCC is commonly treated first with surgery to remove the tumor, followed by radiation therapy (called “adjuvant” radiation, after there is no obvious remaining cancer). This study of 1,965 MCC patients examined whether delayed start of the adjuvant radiation affected the overall survival o...
Adjuvant immunotherapy with nivolumab versus observation in completely resected Merkel cell carcinoma (ADMEC-O): disease-free survival results from a randomized, open-label, phase 2 trial
In this clinical trial, patients who had their MCC removed by surgery were just observed, or given nivolumab, an immunotherapy drug, to assess whether it decreased their chance of MCC recurring. The findings revealed that people who used nivolumab after surgery had 42% less chance of recurrence afte...
