Usefulness of computed tomography aortography and dye infusion in confirming the feeding arteries for effective treatment of a large squamous cell carcinoma of the lower lip with a single intra-arterial infusion chemotherapy combined with radiotherapy
A 73-year-old male presented with a lower lip squamous cell carcinoma (SCC) (23 mm in diameter). Systemic imaging, including computed tomography (CT) and positron emission tomography, showed no evidence of distant metastasis. Due to the large size of the tumor, reconstruction after surgical tumor re...

Summary: | A 73-year-old male presented with a lower lip squamous cell carcinoma (SCC) (23 mm in diameter). Systemic imaging, including computed tomography (CT) and positron emission tomography, showed no evidence of distant metastasis. Due to the large size of the tumor, reconstruction after surgical tumor removal was considered to be difficult. Therefore, we decided to initially perform intra-arterial chemotherapy. Under local anesthesia, a catheter was inserted via the femoral artery. CT aortography from the ascending aorta was performed to visualize the precise vascular anatomy. The tumor's feeding arteries were confirmed by injecting indigo carmine dye through the catheter. Then, 87.5 mg of cisplatin was selectively injected through the left and right facial arteries (total dose of 175 mg). The tumor significantly shrank and almost disappeared 1 month after chemotherapy. Although additional intra-arterial chemotherapy was considered, the risks associated with the procedure meant that radiotherapy was performed instead. There were no signs of recurrence at the 2-year follow-up. In this patient, a single intra-arterial infusion chemotherapy combined with radiotherapy achieved complete disappearance of a large SCC of the lower lip. This treatment strategy allowed us to preserve the functional and cosmetic aspects of the patient's lower lip with minimal side effects. CT aortography and dye infusion were important in confirming the tumor's feeding arteries. |
