Interdisciplinary treatment of large adrenocortical carcinoma infiltrating inferior vena cava

Adrenal tumors are common neoplasms and majority of them are small, benign, hormonally inactive adrenocortical adenomas. Whereas adrenal cancer (ACC) is a rarely occurring (5% of adrenal tumors) but highly aggressive neoplasm. The early diagnosis and complete surgical resection is the only effective treatment option. Laparoscopic adrenalectomy is the gold standard for small and medium tumors. Whereas for large tumors classic adrenalectomy is considered a procedure of choice with a proven better oncological outcome. We herein report a case of a 57-year-old female diagnosed with a large, advanced left adrenal tumor with invasion of vena cava. It was diagnosed in CT and proven in core biopsy. Open adrenalectomy with thoracotomy was conducted to completely resect the tumor by an interdisciplinary team.
