[A Case of Long-Term Disease Control after Administration of Oxaliplatin for Esophagogastric Junction Squamous Cell Carcinoma].

: There are few reports of using oxaliplatin(L-OHP)for esophageal squamous cell carcinoma.We report a case of long-term disease control after administration of L-OHP for esophagogastric junction squamous cell carcinoma(EG).A woman in her 40s was diagnosed with EG(cT3, cN2, cM0, cStage Ⅲ).She received thoracoscopic, laparoscopic-assisted, subtotal esophagectomy with 3-field dissection after 3 courses of preoperative chemotherapy with DCF(docetaxel hydrate, cisplatin, 5- fluorouracil).Reconstruction was achieved using a retrosternally shifted gastric tube and transesophageal gastro-tubing. Pathological examination showed EG(ypT3, ypN2, ypM0, ypStage Ⅲ)(chemotherapy evaluation: Grade 1a).After 12 months, para-aortic lymph node recurrence(#112aoP, #16a2lat)was observed on a follow-up CT examination.First, we administered 5 courses of chemotherapy with SOX(S-1 100mg/m2 day 1-14 and L-OHP 100 mg/m2 day 1).Recurrent lymph nodes shrunk slightly, and there were no new lesions.Subsequently, there was no other adverse event except for Grade 1 chemotherapy-induced neuropathy.Second, we administered 3 courses of chemotherapy with FOLFOX(5-FU 400mg/m2, L-OHP 85mg/m2, Leucovorin 200 mg/m2 day 1, 5-FU 1,600mg/m2/46 hr)in combination with radiotherapy(total 60 Gy/ 30 Fr).Recurrent lymph nodes shrunk slightly, and there were no new lesions.Subsequently, there was no other adverse event except for Grade 1 chemotherapy-induced neuropathy.No new recurrence was observed 19 months after the first recur- rence.The patient continues to receive weekly nab-PTX(85mg/m2).A regimen that includes L-OHP is useful in the treatment of advanced or recurrent esophageal squamous cell carcinoma.
