Article highlights & insights
The rate of growth of primary melanoma is a robust predictor of aggressiveness, but the mutational profile of fast-growing melanomas (FGMM) and the potential to stratify patients at high risk of death has not been comprehensively studied.
In this observational study, the authors investigate the epidemiologic, clinical, and mutational profile of primary cutaneous melanomas with a thickness ≥ 1 mm, stratified by rate of growth.
Two hundred patients were enrolled, among wom 70 had FGMM. The relapse-free survival was lower in the FGMM group (P = .014). FGMM had a higher number of predicted deleterious mutations within the 40 genes than nonFGMM (P = .033). Ulceration (P = .032), thickness (P = .006), lower sun exposure (P = .049), and fibroblast growth factor receptor 2 (FGFR2) mutations (P = .037) were significantly associated with fast growth.
Authors conclude that fast growth is linked to specific tumour biology and environmental factors. Ulceration, thickness, and FGFR2 mutations are associated with fast growth. Screening for FGFR2 mutations might provide an additional tool to better identify FGMM, which are probably good candidates for adjuvant therapies.

We strive to make our community a welcoming, caring and enthusiastic one, fuelling ambition with opportunities for training and mentoring to help us all achieve our personal and professional goals.
“We are so pleased to have received the funding to enable us to test our hypothesis in the lab. If we can create a new medicine that can precisely target a specific type of cell within the tumour, and restore anti-cancer immune responses, this will be a game-changer for oesophageal cancer patients “

“My charity bake sales – known as “David’s Great British Bake Off” – are always a hit, home baked products taste so much better than shop bought and are greatly appreciated by staff!”
David Jenkins
Purchasing Officer
“We’ve seen some remarkable responses, with an improvement for some patients within days. This is an early phase trial so there’s a lot more work to do. But the data we have so far is very encouraging and could help many thousands of people in the future”
