[Multidisciplinary Treatment for a Patient with Recurrent Gastric Cancer, Presenting 13 Years after the Radical Gastrectomy].

Abstract

A 72-year-old woman was referred to our hospital for further examination of para-aortic lymph node swelling and elevated carbohydrate antigen 19-9 levels. Thirteen years ago, she had undergone distal gastrectomy for gastric cancer, and the final diagnosis was T4N1M0, Stage ⅢA. Abdominal contrast-enhanced computed tomography(CT)showed an enlarged para-aortic lymph node measuring 25 mm. Endoscopic ultrasound-guided fine-needle aspiration was performed, and biopsy specimens showed poorly differentiated adenocarcinoma. Under the clinical diagnosis of gastric cancer recurrence, the patient received chemotherapy with cisplatin plus S-1. After 5 cycles of systemic treatment, abdominal CT revealed a marked shrinkage of the para-aortic lymph node metastasis, with an 84% decrease. At 15 months after treatment, we switched to S-1 monotherapy because of general fatigue and the patient's preference. However, 22 months after the treatment, the patient was treated with ramucirumab due to the progression of para-aortic lymph node metastasis. After 33 months, the patient developed metastasis in the left ovary, measuring 11.0×8.5 cm. Because there was no evidence of further metastatic lesions in any other organs, she underwent left oophorectomy. After 37 months, the patient developed metastasis in the left cerebellum, measuring 3.2×2.5 cm, accompanied with headache and nausea. The patient underwent metastasectomy of the left cerebellum as palliative treatment. Simultaneous physical examination revealed a painful nodular elevated lesion in the subcutaneous tissue of the posterior neck region, measuring 18×15 cm. Pathological examination of the biopsy specimen showed infiltration of poorly differentiated adenocarcinoma cells into the subcutaneous mass. The patient received radiation therapy; however, she died due to septic shock with hydronephrosis 39 months after starting chemotherapy. Although late recurrence of gastric cancer is rare, identification of risk factors and the development of novel treatments should be achieved through further studies and accumulation of data from such cases.
