Clinicopathologic Presentation and Natural History of Anorectal Melanoma: A Case Series of 18 Patients
View abstract on PubMed
Summary
This summary is machine-generated.Anorectal melanoma, a rare cancer, often presents late and is misdiagnosed. Wide local excision showed better survival than abdominoperineal resection in a small patient series.
Area Of Science
- Gastroenterology
- Surgical Oncology
- Oncology
Background
- Anorectal melanoma is a rare malignancy with a poor prognosis.
- Its presentation is often nonspecific, leading to delayed diagnosis and treatment.
Purpose Of The Study
- To describe the clinicopathologic and prognostic parameters of anorectal melanoma.
- To evaluate treatment outcomes and identify factors influencing survival.
Main Methods
- Retrospective review of 18 patients with histologically confirmed anorectal melanoma.
- Analysis of clinicopathologic data, treatment modalities, and survival outcomes.
Main Results
- Late diagnosis (stage II or worse) was observed in 44.5% of patients.
- Disease-specific mortality was high at 66.7%.
- Wide local excision was associated with significantly better disease-specific survival compared to abdominoperineal resection (P=.04).
Conclusions
- Anorectal melanoma is an aggressive malignancy with high mortality.
- Early diagnosis and surgical management, potentially including wide local excision, are crucial.
- Further research is needed to optimize treatment strategies.
