ABSTRACT
A 69-year-old man was diagnosed with advanced gastric cancer in the upper body of the stomach and underwent total gastrectomy with D2 lymph node dissection. At the diagnosis, the pathological stage was T2N3M0(Stage â
¢A). The patient underwent adjuvant chemotherapy with S-1 for a year. Two years after surgery, metastasis in subclavian and axillary lymph nodes was diagnosed by positron emission tomography-computed tomography(PET-CT). He rejected systemic chemotherapy, and radiotherapy(RT)at 56 Gy/28 Fr was administered. After RT, the metastatic lymph node completely regressed. However, CT showed lymph node metastasis in the right cervical, supraclavicular, and mediastinal zones over 1 year and 6 months after RT. These body regions received RT at a total dose of 40 Gy/20 Fr, and cancer significantly shrank again. Five years after following the second RT, the patient remains alive with no signs of relapse. RT may be a promising method for localized distant metastasis in patients who did not receive chemotherapy.
