Tokyo, March 15 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000060938) titled 'Aesthetic Subunits and Optimal Surgical Margins in the Surgical Management of Facial Basal Cell Carcinoma' on March 15.

Study Type: Observational

Primary Sponsor: Institute - Hirosaki University Graduate school of Medicine

Condition: Condition - Facial Basal Cell Carcinoma Classification by malignancy - Malignancy Genomic information - NO

Objective: Narrative objectives1 - Basal cell carcinoma is a malignant skin tumor that rarely metastasizes distantly and is generally considered curable with appropriate treatment. Several factors influence the management of BCC, including tumor size, location, tumor borders, degree of pigmentation, and histopathological findings. BCC frequently occurs in the head and neck region, particularly on the face. Due to both anatomical and aesthetic considerations, it is often difficult in practice to achieve an adequate surgical margin (more than 4 mm) when excising facial lesions. Consequently, numerous studies have compared different margin widths to determine the appropriate surgical margin. In this study, using existing medical records and pathological specimens, facial BCCs will be classified according to aesthetic subunits. The histopathological findings and postoperative recurrence rates for each subunit will be analyzed in order to evaluate appropriate surgical margins and reconstructive strategies. Basic objectives2 - Safety,Efficacy
