| 内容記述 | Background: The aim of this study was to clarify the necessity of routine chest CT in the follow-up of postoperative gastric cancer (GC) and the optimal CT interval based on risk determined by pathological stage (PS; pT and pN) to minimize radiation exposure to patients. Method: The subjects were 361 postoperative patients with primary GC. We retrospectively evaluated sites of recurrence, time to recurrence revealed on chest and abdominopelvic CT, and PS. Results: Forty-two patients experienced recurrences. The pN factor was more strongly associated with thoracic metastasis than pT factor in patients with N0-1 (n = 278) versus those with N2-3 (n = 83) (p < 0.05) and in those with T1-2 versus those with T3-4 (p = 0.48). None of the 278 patients with pN0-1 had chest metastasis. Among the 83 atients with pN2-3, only abdominal lymph node recurrence was significantly associated with thoracic metastasis. Recurrences were detected within two years after resection in 38 patients (90 %) regardless of PS. Conclusion: Abdominal lymph node recurrence as well as pN factor were significantly associated with thoracic metastases and actually none of patients with pN0-1 had chest metastases. These facts implied limited role of routine chest CT for those patients. |
