Abstract

Clear cell carcinoma (CCC) of the abdominal wall is a rare and agressive disease. We aim to elucidate the clinical and prognostic characteristics of this disease. Medical records of ten patients diagnosed with CCC of the abdominal wall at Fudan University Shanghai Cancer Center were reviewed. We illustrate the clinical characteristics, treatment modality, and development of local recurrence or distant metastasis, as well as the survival outcome. The median (range) age of patients was 47 (39-61) years old. All patients had a history of cesarean section and abdominal wall endometriosis. All patients had primary surgery before referred to our center. Seven patients had only tumor resection, while two patients had lymph node metastasis at primary diagnosis. Four patients underwent supplementary surgery, and all postoperative pathology were negative. Genetic analyses had also been performed. The median (range) follow-up time was 20 (12-59) months. Local recurrence and lymph node metastasis were the most common recurrence types. The median (95% confidence interval) PFS was 11 (8.08-13.92) months. In summary, primary surgery should consider wide tumor resection and lymph node dissection. Adjuvant chemotherapy and radiotherapy should be recommended for potential benefits. More cases are still needed to elucidate the clinical management of this disease.
