This research aims to observe the safety and effectiveness of dabrafenib and trametinib in patients with BRAF V600E mutation-positive unresectable advanced or recurrent solid tumors, excluding colorectal cancer. It is a prospective, multicenter, single-arm, non-interventional observational study conducted through a central registration system using electronic data capture. The study includes both adult and pediatric patients, with long-term monitoring planned to collect comprehensive safety data. Patients already prescribed Tafinlar/Mekinist (dabrafenib and trametinib) before joining the study will be enrolled without treatment allocation or changes. The study targets 65 adult patients for effectiveness analysis and approximately 20 pediatric patients. Pediatric patients will be observed for up to 8 years after starting treatment to gather long-term information, while adult patients will be followed for one year post-treatment initiation. During participation, patient safety and treatment response will be monitored through reports of adverse events and overall response rates. Pediatric patients will have ongoing safety assessments related to skeletal and sexual development over the 8-year period. Adults will have their treatment response evaluated over one year. Data collection includes long-term follow-up regardless of treatment discontinuation, aiming to provide comprehensive post-marketing surveillance information on these medications.
