Gastric cancer incidence is high in several countries, and management of advanced gastric cancer remains a challenge. Chemotherapy for unresectable gastric cancers is still evolving, and achieving a complete cure is difficult. Although a clinical complete response to chemotherapy has been reported in patients with unresectable gastric cancer, the chemotherapy duration for these patients is unclear. Here, we report the case of a 71-year-old man who presented with abdominal discomfort. Upper endoscopy revealed advanced gastric cancer on the upper gastric body. Histopathological examination revealed a poorly differentiated adenocarcinoma. Computed tomography revealed regional lymph node and multiple bilobar hepatic metastases. Radical surgery was not possible; therefore, palliative resection of the primary lesion was planned for symptomatic improvement. Tegafur, 5-chloro-2,4-dihydro­pyrimidine, and potassium oxonate were administered prior to surgery, and proximal gastrectomy was performed. Tegafur, 5-chloro-2,4-dihydropyrimidine, and potassium oxonate administration was reinitiated after surgery. A clinical complete response was achieved in the 8th postoperative month, with no hepatic metastases noted on radio imaging. Computed tomography performed in the 1st postoperative year revealed ascites; however, the cytological examination findings were negative. The initial chemotherapy was discontinued, and paclitaxel administration was commenced. Computed tomography performed annually thereafter demonstrated no recurrence, and paclitaxel was discontinued in the 9th postoperative year. The patient remained recurrence free at 12 years postoperatively. For elderly patients like the one presented here, it may be necessary to consider ceasing chemotherapy; however, because it is possible for a complete clinical response over the long term, it should be continued if the patient is well.

Liver metastasis from gastric cancer has a very poor prognosis. Herein, we present two cases of liver metastases (synchronous and metachronous) from advanced gastric cancer. In the first case, the patient underwent radical subtotal gastrectomy. Liver metastases occurred 6 months after surgery while the patient was receiving adjuvant chemotherapy, but two hepatic tumors were successfully removed by radiofrequency ablation (RFA). In the second case, liver metastases occurred 15 months after surgery for gastric cancer. The patient also received RFA for one hepatic tumor, and other suspicious metastatic tumors were treated with systemic chemotherapy. Although these case presentations are limited for the efficacy of RFA treatment with systemic chemotherapy for hepatic metastases from gastric cancer, our findings showed long-term survival (overall survival for 108 and 67 months, respectively) of the affected patients, without recurrence. Therefore, we suggest that RFA treatment with systemic chemotherapy could be an effective alternative treatment modality for hepatic metastases from gastric cancer.

205 Background:TAS-118 (S-1 and leucovorin) + oxaliplatin (L-OHP) improved overall survival (OS) compared to S-1 + cisplatin for patients (pts) with advanced gastric cancer (GC) (Kang, Lancet Oncol. 2020). This study investigated the feasibility of peri (pre and post)-operative (op) chemotherapy (chemo) with TAS-118 ± L-OHP in pts with locally advanced resectable GC. While it was reported that pre-op TAS-118 + L-OHP followed by D2 gastrectomy was well tolerated and showed promising efficay (Takahari, ASCO-GI. 2020), the recommended post-op chemo regimen, TAS-118 or TAS-118 + L-OHP, has yet to be determined. Methods:Eligible pts with GC of clinical T3-4N1-3M0 were enrolled. The protocol treatment consisted of pre-op chemo with 4 courses of TAS-118 (40-60 mg/body, orally, twice daily, 7 days) + L-OHP (85 mg/m2, intravenously, day 1) in a 2-week cycle, and gastrectomy with D2 lymphadenectomy, followed by post-op chemo with 12 courses of TAS-118 (step 1) and 8 courses of TAS-118 + L-OHP (step 2). Step 2 was started if the dose-limiting toxicity (DLT) occurred in < 6 of 10 pts in step 1. Up to 20 pts were included in the analysis of feasibility after a recommended regimen was determined. Results:Between December 2016 and February 2019, 45 pts were enrolled. The numbers of pts with cT3/4a and cN1/2/3 were 13/32 and 25/17/3, respectively. Excluding 14 pts (4 achieving pathological complete response, 4 not satisfying the criteria for post-op chemo, 3 physician judgement or pt withdrawal, 2 progressive disease, 1 adverse event [AE]), 31 pts (11/20 in step 1/2) received the post-op chemo. No DLT was observed in either step. The post-op chemo completion rate was 90.9% (95% CI, 63.6-99.5) in step 1 and 80.0% (95% CI, 59.9-92.9) in step 2. The median relative dose intensity of TAS-118 in step 1 was 83.3%, and those of TAS-118 and L-OHP in step 2 were 69.9% and 74.3%, respectively. One pt in step 2 discontinued post-op chemo due to AE. Grade ³ 3 AEs observed in ≥ 10% of pts were weight loss in both step 1 and step 2 (2 in each), and hypokalemia (n = 3) and neutropenia (n = 2) in step 2. At 1-year follow-up after the last pt was enrolled, recurrence-free survival and OS rates were 91.1% (95% CI, 78.0-96.6) and 100%, respectively at 12 months, and 69.1% (95% CI, 49.6-82.3) and 95.5% (95% CI, 71.9-99.3), respectively at 24 months. Conclusions:Taken together with the feasibility and efficacy of pre-op chemo, peri-op chemo with TAS-118 + L-OHP with D2 gastrectomy was well tolerated and showed promising efficacy.
