Terms & Conditions of Use

Surgical excision of cutaneous leiomyosarcoma, a rare skin cancer, can achieve excellent outcomes. Even with narrow margins and poor prognostic factors, local recurrence and distant metastasis were avoided in a recent study.

Area of Science:

Dermatology
Surgical Oncology
Oncology

Background:

Cutaneous leiomyosarcoma (CLS) is a rare soft-tissue malignancy.
CLS has a low metastatic potential but high local recurrence rates (14-42%) after surgical excision.
Optimal surgical margins for CLS are not well-defined in current literature.

Purpose of the Study:

To evaluate the outcomes of surgical excision for cutaneous leiomyosarcoma.
To determine the effectiveness of narrow surgical margins in preventing local recurrence and distant metastasis.

Main Methods:

Retrospective review of eight patients with cutaneous leiomyosarcoma treated over 12 years.
Analysis of surgical excision margins, prognostic factors, and patient outcomes, including local recurrence and distant metastasis.

Main Results:

None of the eight patients developed local recurrence or distant metastases.
This occurred despite seven patients having poor prognostic factors.
Excision margins varied widely, ranging from 1 to 27 mm.

Conclusions:

Complete surgical excision with narrow margins appears effective for cutaneous leiomyosarcoma.
Close patient observation for at least 5 years post-surgery is recommended.
Findings suggest a favorable prognosis for CLS when completely excised.
