Decreased UV Exposure in Children May Be behind Predicted Reduction in Deaths from Melanoma

“Death from melanoma over the next several decades should stabilize and then decline in light-skinned populations, according to study results.

“This reduction in melanoma mortality — which may be more apparent in younger generations — may be linked to UV exposure patterns, researchers wrote.

“ ‘Independent from screening or treatment, over next decades, death from melanoma is likely to become an increasingly rare event,’ Philippe Autier, MD, director of the International Prevention Research Center in Lyon, France, and colleagues wrote. ‘The temporary epidemic of fatal melanoma was most probably due to excess UV exposure of children that prevailed in 1900 to 1960, and mortality decreases would be due to progressive reductions in UV exposure of children over the last decades.’ ”

Progression of RAS-Mutant Leukemia during RAF Inhibitor Treatment

Vemurafenib, a selective RAF inhibitor, extends survival among patients with BRAF V600E–mutant melanoma. Vemurafenib inhibits ERK signaling in BRAF V600E–mutant cells but activates ERK signaling in BRAF wild-type cells. This paradoxical activation of ERK signaling is the mechanistic basis for the development of RAS-mutant squamous-cell skin cancers in patients treated with RAF inhibitors. This study reports the accelerated growth of a previously unsuspected RAS-mutant leukemia in a patient with melanoma who was receiving vemurafenib. Exposure to vemurafenib induced hyperactivation of ERK signaling and proliferation of the leukemic cell population, an effect that was reversed on drug withdrawal.


New melanoma trial initiated at Moffitt Cancer Center to investigate utility of immunotherapy biomarkers

Phase I melanoma patient trial will test whether the drug PV-10 works better in patients with a distinct immune biomarker signature in both blood and tumor tissue.


Circulating tumor cells may be predictive for recurrence and survival in melanoma patients

Circulating tumor cells detected in the blood of stage III melanoma patients may be a predictive blood biomarker helpful for deciding which patients could benefit from aggressive adjuvant therapy.
