Abstract

BACKGROUND:

Reported recurrence rates for transected nonmelanoma skin cancer (NMSC) vary widely, and few studies have addressed recurrence of tumors followed clinically or treated with nonsurgical modalities.

METHODS:

Retrospective review of dermatopathology records from January 1999 to January 2005 was conducted to identify biopsies or excision specimens with histologically transected basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) which were not subsequently excised. Patient and tumor characteristics associated with recurrence were analyzed in a subgroup of patients with predominantly 'low-risk' and/or minimally transected NMSCs. Prospective follow up was performed through March 31, 2008. Data was analyzed with Chi-square and Fishers exact tests and multivariate logistic regression.

RESULTS:

Of 376 transected NMSCs, 27 (7.2%) recurred, including 20 (9%) of 223 BCCs and 7 (4.6%) SCCs in situ of 153 SCCs. The overall recurrence rate of the 124 minimally transected NMSCs was even lower (5.6%). Multivariate logistic regression identified three significant predictors of recurrence: tumor location on the head and neck (p = 0.041), tumor size (p = 0.00741) and superficial subtype of BCC (p = .035).

CONCLUSIONS:

Although surgical excision of NMSC remains the standard of care, observation or nonsurgical treatment may be acceptable in many cases of incompletely excised low-risk or minimally transected NMSCs.
