Temozolomide (TMZ)-based chemotherapy is a primary regimen for melanoma patients who have failed targeted therapy or immunotherapy. However, the low response rate of TMZ-based chemotherapy challenges the patients' prognosis. BRAF mutation is the most frequently mutated site in melanoma.

Purpose: Precision medicine plays an important role in the treatment of patients with advanced melanoma. Despite its high incidence in White patients, advanced melanoma is rare in Asian countries, hampering prospective clinical trials targeting the Asian population. This retrospective study aimed to elucidate the real-world molecular diagnoses and outcomes of Japanese patients with melanoma using comprehensive genome profiling (CGP).

Summary: Craniopharyngiomas (CPs) are rare brain epithelial tumours arising in the suprasellar region, infiltrating adjacent areas causing visual loss, panhypopituitarism, cognitive deficits and morbid obesity. Papillary CPs (PCPs) harbour in 94% BRAF mutation cases. Two patients with PCP and BRAF V600E mutations but with different tumour status were treated with BRAF and MEK inhibitors.

Colorectal cancer (CRC) is well characterized in terms of genetic mutations and the mechanisms by which they contribute to carcinogenesis. Mutations in APC, TP53, and KRAS are common in CRC, indicating key roles for these genes in tumor development and progression. However, for certain tumors with low frequencies of these mutations that are defined by tumor location and molecular phenotypes, a carcinogenic mechanism dependent on BRAF mutations has been proposed.
