Background: Patients diagnosed of keratinocyte cancer (basal cell carcinoma and cutaneous squamous cell carcinoma) or non-melanoma skin cancer (NMSC) have a higher risk of develop a second cutaneous malignant neoplasm.
Objective: Our aim was to describe the frequency, incidence rate and risk factor predisposing to develop a second neoplasm in a patients cohort treated with Mohs Micrographic Surgery (MMS).
Methods: Prospective cohort of consecutive patients undergoing MMS in 22 representative Spanish centres (July 2013-February 2020) REGEMOHS. Variables analysed in a logistic multilevel multivariate analysis included characteristic of patients, frequency of second cutaneous neoplasm, incidence rate and risk factors.
Results: 4768 patients underwent MMS: 4397 (92%) basal cell carcinoma and 371 (8%) cutaneous squamous cell carcinoma. Mean follow up was 2,4 years. A second malignant neoplasm was diagnosed in 1201 patients (25%). 1013 (21%) were basal cell carcinomas; 154 (3%) cutaneous squamous cell carcinoma and 20 (0,4) melanomas. Incidence rate was 107 (101-113) cases per 1000 person-year for any tumour; 90 (85-96) basal cell carcinoma, 14 (12-16) cutaneous squamous cell carcinoma and 2 (1-3) melanoma. Significant risk factors for developing a second cutaneous malignant neoplasm were previous history of multiple tumours before diagnosis (RR: 4.6 95% CI: 2.9-7.1), immunosuppression (RR: 2.1 95% CI: 4-3.1) and male (RR: 1.6 95% CI: 1.4-1.9).
Conclusion: Patients diagnosed of keratinocyte carcinoma who underwent MMS have a higher risk for developing a second cutaneous malignant neoplasm. These are more frequent in patients with previous history of multiple neoplasm, immunosuppression and males.
