Popis: Background Evidence is controversial and limited concerning whether surgical delays are associated with tumor growth for cutaneous squamous cell carcinomas (SCCs) and basal cell carcinomas. Objective Identify tumor subpopulations that may demonstrate an association between tumor growth and surgical delay. Methods We retrospectively analyzed 299 SCCs and 802 basal cell carcinomas treated with Mohs surgery at a single institution. Time interval from biopsy to surgery represented surgical delay. Change in major diameter (ΔMD) from size at biopsy to postoperative defect represented tumor growth. Independent predictors of ΔMD were identified by multivariate analysis. Linear regression was then utilized to assess for whether the ΔMD from these independent predictors trended with surgical delay. Results Surgical delays ranged from 0 to 331 days. Among SCCs, histologic subtype and prior treatment were identified as independent predictors of ΔMD. Significant associations between ΔMD and surgical delay were found for poorly- and moderately-differentiated SCCs, demonstrating growth rates of 0.28 cm and 0.24 cm per month of delay, respectively. The ΔMD for SCCs with prior treatment and basal cell carcinoma subgroups did not vary with surgical delay. Limitations Retrospective design, single center. Conclusion Surgical delays of less than a year were associated with tumor growth for higher-grade SCCs, with effect sizes bearing potential for clinical significance.
