Symptomatic gastrointestinal metastases from malignant melanoma

Area of Science:

• Oncology
• Gastroenterology
• Surgical Oncology

Background:

• Malignant melanoma can metastasize to the gastrointestinal tract, causing significant symptoms.
• Gastrointestinal metastases from melanoma present a challenge in patient management and prognosis.

Purpose of the Study:

• To review the outcomes of patients with gastrointestinal metastases from malignant melanoma.
• To evaluate the role and effectiveness of surgical intervention in managing these symptomatic metastases.

Main Methods:

• Retrospective review of 22 patients with gastrointestinal metastases from malignant melanoma.
• Analysis of surgical interventions, palliation, and survival rates.

Main Results:

• Sixteen of 22 patients underwent abdominal surgery, achieving satisfactory palliation.
• Thirteen patients with symptomatic intestinal metastases had a median survival of 4.5 months post-resection.
• One patient remained disease-free at 15 months, and two lived over 33 months after surgery.

Conclusions:

• Surgical management can provide effective palliation for symptomatic gastrointestinal metastases of malignant melanoma.
• Resection of involved intestinal segments may improve survival and lead to long-term disease control in select patients.
