RESUMO

BACKGROUND: Basal cell carcinoma (BCC) is the most common skin cancer. While Mohs micrographic surgery is commonly accepted for BCC treatment, surgical excision with free margins is widely considered the best treatment modality for BCCs in Japan. However, little is known about the predictors of the invasion levels of BCCs. OBJECTIVE: To investigate the optimization of deep surgical margins by identifying factors significantly influencing the invasion levels of facial BCCs. METHODS: The tumor invasion level was defined as the deepest part of a tumor. Tumor thickness was measured from the top of the granular layer to the deepest extension of the tumor or from the ulcer base overlying the deepest point of invasion in ulcerated lesions. Factors independently associated with tumor thickness and invasion level were identified by multivariate analysis. Six variables were tested: age, sex, anatomical region (nose, orbit, others), histologic pattern (aggressive, non-aggressive), presence of pigmentation, and diameter. RESULTS: We included 718 cases of facial BCCs involving 705 Japanese patients. The most frequent anatomical region and histologic pattern were the nose and nodular pattern, respectively. Only tumor diameter showed a correlation with tumor thickness (ß = 0.377, P < 0.001). Tumor diameter (AOR = 71.189, 95 % CI: 11.420-430.931, P = 0.01) and the following anatomical regions showed correlations with the invasion level: nose/others: AOR=2.769, 95 % CI: 1.235-6.493, P = 0.01; orbit/others: AOR=6.369, 95 % CI: 2.728-15.429, P < 0.001; orbit/nose: AOR=2.300, 95 % CI: 1.056-4.984, P = 0.04. CONCLUSIONS: This study serves as a guide for optimizing deep surgical margins and planning surgery for facial BCCs considering independently associated factors.

RESUMO

We report on the first case of pyogenic granulomas caused by afatinib. We also review the current literature concerning pyogenic granulomas caused by epidermal growth factor receptor tyrosine kinase inhibitors.

RESUMO

Nivolumab was developed as a monoclonal antibody against programmed death receptor-1, an immune checkpoint inhibitor which negatively regulates T-cell proliferation and activation. Intravenous administration of nivolumab was approved for the treatment of unresectable malignant melanoma in 2014 in Japan. When advanced melanoma patients were treated with nivolumab, median overall survival became longer. Overall survival rate was significantly better in nivolumab-treated melanoma patients than dacarbazine-treated melanoma patients. Nivolumab had an acceptable long-term tolerability profile, with 22% of patients experiencing grade 3 or 4 adverse events related to the drug. Therefore, nivolumab can become an alternative therapy for advanced malignant melanoma.
