Prognostic factors in metastatic melanoma

Area of Science:

• Oncology
• Clinical Research
• Cancer Prognostics

Background:

• Metastatic melanoma causes significant mortality in the United States annually.
• Understanding prognostic factors is crucial for improving patient outcomes.

Purpose of the Study:

• To identify factors influencing survival and response rates in patients with metastatic melanoma.
• To provide insights for designing and analyzing clinical trials for this disease.

Main Methods:

• Analysis of response and survival data from 635 patients across three Eastern Cooperative Oncology Group trials.
• Utilized time-dependent proportional-hazards model for response analysis.

Main Results:

• Poorer survival associated with poor performance status, symptoms (appetite loss, fever, nausea/vomiting), male sex, and rapid recurrence.
• Liver metastasis and increased non-bone metastatic sites (including skin, soft tissue) correlated with worse prognosis.
• Objective tumor response, though infrequent (11%), significantly improved survival compared to non-responders.

Conclusions:

• Identified key prognostic indicators for metastatic melanoma.
• Findings offer valuable guidelines for future clinical trial design and analysis in metastatic melanoma research.
