Cutaneous melanoma in patients with sarcoma
Cancer
|February 15, 1997
Summary
This study investigated the link between melanoma and sarcoma, finding an increased occurrence of malignant peripheral nerve sheath tumors and visceral sarcomas. A predisposition toward cancer, indicated by family history and multiple primary tumors, was observed in patients with both melanoma and sarcoma.
Area of Science:
- Oncology
- Cancer Epidemiology
Background:
- Investigating the co-occurrence of cutaneous melanoma and sarcoma.
- Reviewing institutional experience with malignancies in sarcoma patients.
Purpose of the Study:
- To determine if there is an association between melanoma and sarcoma.
- To identify specific sarcoma subtypes or characteristics associated with melanoma.
Main Methods:
- Retrospective review of 48 patients with both melanoma and sarcoma.
- Data collection from institutional cancer registry (1943-1996).
- Comparison of patient cohort with broader sarcoma population data.
Main Results:
- Malignant peripheral nerve sheath tumors (MPNT) were more common in patients with both melanoma and soft tissue sarcoma (STS) (13% vs 4%).
- Visceral STS was also more frequent in this combined diagnosis group (27% vs 15%).
- Liposarcoma was less common (2% vs 22%) and a high rate of positive family cancer history (50%) and third primary tumors (25%) was noted.
Conclusions:
- No distinct "melanoma/sarcoma" syndrome was identified.
- MPNT and visceral sarcomas occurred more frequently than expected.
- Strong family cancer histories and multiple primary malignancies suggest a potential cancer predisposition.
