Advanced cutaneous squamous cell carcinoma of the trunk and extremity: analysis of prognostic factors.
BACKGROUND
Patients with squamous cell carcinoma (SCC) of the skin may exhibit locally advanced or metastatic disease and present a challenging management problem.


METHODS
A retrospective review of 40 patients with advanced SCC of the trunk or extremity managed at Roswell Park Cancer Institute from 1982 through 1992 was performed to identify clinical and pathologic factors that influenced outcome.


RESULTS
There were 27 males and 13 females with a median age of 61 years. Median follow-up was 24 months. Surgical resection to control the primary tumor was often extensive. Amputation was required in nine patients, hemipelvectomy in three patients, and hemicorporectomy in one patient. Median survival was 28 months, and 5-year survival was 43%. Univariate analysis identified stage (P = 0.04), size (P = 0.0001), type of surgical procedure (P = 0.009), and margins of resection (P = 0.005) as having prognostic significance. On multivariate analysis, stage (P = 0.04) and size (P = 0.02) were found to be significant.


CONCLUSIONS
Optimum treatment for advanced SCC of the trunk and extremity involves surgical resection with uninvolved margins. The role of elective node dissection remains undefined. Investigation is needed to define the role of neoadjuvant therapy that may improve functional and cosmetic results.
