Abstract
No effective systemic chemotherapy is well-established in basal cell carcinoma. We report a case with three simultaneous malignancies: colon cancer, basal cell carcinoma, and smoldering multiple myeloma. The patient was treated with capecitabine and oxaliplatin after surgery for colon cancer. Surprisingly, he achieved a complete response for basal cell carcinoma. This is the first report of this chemotherapy regimen in basal cell carcinoma. This finding suggests that combination capecitabine and oxaliplatin can be a treatment option for patients unable to receive local therapy.
