title: Synchronous triple primary cancers occurring in the stomach, kidney, and thyroid.
abstract: We report an unusual case of synchronous triple primary cancer of the stomach, kidney, and thyroid in a 50-year-old male patient. Initial esophagogastroduodenoscopy with biopsy for the medical check-up revealed poorly differentiated adenocarcinoma. We performed an abdominal/pelvic computed tomography scan for staging and incidentally found a 1.7-cm exophytic hypervascular mass in the left kidney. Thyroid ultrasonography showed suspicious malignant nodules suspicious with multiple lymph nodes (LNs) metastasis in the right side of the neck. Subsequent fine needle aspiration biopsy of a nodule and a LN was performed. Cytologic report revealed papillary thyroid carcinoma with lateral LNs metastasis. Our integrate oncology team performed radical subtotal gastrectomy, partial nephrectomy, and total thyroidectomy with modified radical neck dissection. The postoperative pathologic finding was well-differentiated gastric adenocarcinoma (T1N0M0; stage 1A), renal cell carcinoma (T1aN0M0; stage 1), and papillary thyroid carcinoma (T4bN1bM0; stage 4B). He received postoperative a radio-active iodine ablation and is doing well with no recurrence.
