ABSTRACT: BACKGROUND: We hypothesized that the survival rate of patients undergoing R0 esophagectomy after induction chemotherapy or chemoradiotherapy for unresectable T4 esophageal cancer (URT4) would be similar to that of patients undergoing esophagectomy for immediately resectable esophageal cancer with no unfavorable prognostic factors (RNU). METHODS: Between April 2002 and June 2012, 87 of 283 patients with esophageal cancer who presented at the University Hospital of the Ryukyus were enrolled in this prospective cohort study. Tumors were classified as RNU and URT4 in 44 and 43 of the 87 patients, respectively. Outcomes of treatment for URT4 patients were compared with those of RNU patients. RESULTS: The R0 resection rate (61 %) and in-hospital mortality rate (20 %) of URT4 patients were significantly poorer than those of RNU patients (98 and 2.3 %, respectively), although the morbidity rate was similar in the two groups (63 and 52 %, respectively). The 5-year survival rate (35 %) of URT4 patients was significantly poorer than that of RNU patients (67 %) in the intention-to-treat analysis. However, no significant difference was noted between the two survival curves for cases of R0 resection (5-year survival rate, 60 % vs. 69 %). Multivariate analysis revealed R status as the only significant independent prognostic factor for URT4 patients (P < 0.001; hazard ratio = 8.279). CONCLUSIONS: Satisfactory survival rates can be achieved if R0 resection is performed after induction treatment in patients with T4 esophageal cancer, although secondary radical esophagectomy is associated with a higher risk of in-hospital mortality.

ABSTRACT: Phlegmonous infection involving the digestive tract has been reported to have a poor prognosis. However, the pathogenesis and clinical features of acute phlegmonous esophagitis have remained unclear due to the rarity of the disease. We herein report a case of acute phlegmonous esophagitis that showed a fulminant course during chemoradiotherapy for uterine cancer. The patient developed septic shock 10 h after postprandial nausea and vomiting, and a computed tomographic scan showed diffuse thickening of the esophageal wall. Severe leukopenia that was refractory to the administration of granulocyte colony-stimulating factor persisted during the first few days. The patient fortunately survived after intensive treatment. The acute phlegmonous esophagitis of the present case might have been evoked and worsened by chemoradiotherapy due to its emetic and myelosuppressive adverse effects, respectively. Although its incidence is extremely rare, acute phlegmonous esophagitis may occur as a life-threatening complication of chemoradiotherapy.

ABSTRACT: To retrospectively analyze the results of radical radiotherapy for patients with superficial esophageal cancer (SEC).
Forty-eight patients with SEC were reviewed. The median dose of external beam radiotherapy was 66 Gy (range, 30 to 70 Gy). Intraluminal brachytherapy was used in 10 patients, and 15 patients (31%) underwent chemotherapy. The median follow-up period was 28 months (range, 4 to 116 months).
Sixteen patients had recurrence (11 patients: in-field local recurrence; 3 patients: regional lymph node recurrence; 2 patients: distant metastasis), and the 5-year local control (LC) rate was 74.2%. The 5-year overall survival and disease-free survival (DFS) rates were 44.5% and 48.6%, respectively. Patients with clinical N1 disease (5-year DFS: 0%) had significantly poorer DFS than patients with clinical N0 disease (5-year DFS: 51%, p=0.019).
Radical radiotherapy yielded relatively favorable LC rates in patients with SEC, and clinical N stage was a significant prognostic factor for DFS.

ABSTRACT: This is a case report of a gastro-lymphatic fistula which appeared during chemoradiotherapy for advanced esophageal cancer. A 60-year-old male was referred to the University of the Ryukyus Hospital because of a 10 kg monthly weight loss and dysphagia. Computed tomography (CT) scans indicated thickened esophageal wall at the lower thoracic esophagus and a swollen lymph node attached to the lesser curvature of the stomach. Histological analysis of the biopsy specimen revealed poorly differentiated squamous cell carcinoma and the diagnosis was of advanced esophageal cancer. A combination of chemotherapy (nedaplatin and 5-fluorouracil) and radiotherapy was initiated. After radiotherapy (20 Gy), CT scans revealed that the swollen lymph node penetrated the gastric wall resulting in a gastro-lymphatic fistula. Although gastrostomy and intestinal fistula repair were performed for gastric decompression and tube feeding, respectively, the patient's general status did not improve and he died two months after interruption of his chemoradiotherapy. The results indicate that there may be some risks of gastro-lymphatic fistula in patients treated with concurrent chemoradiotherapy for advanced esophageal cancer when there are possible signs of involvement by CT scans.

ABSTRACT: We report a case with gastric cancer and lung metastasis,who responded remarkably to combination chemotherapy using S-1 and weekly CDDP. A 59-year-old man was hospitalized for aphagia. Based on upper GI endoscopy and CT,type 3 gastric cancer associated with lung metastases was diagnosed. Cardiac gastrectomy, D 1 dissection, intermittented small intestine were performed. At 18 days postoperatively,the patient was administered 3 courses of S-1 (100 mg/body, on day 1-21) and CDDP (30 mg/body, on day 8, 15, 22) every 5 weeks. The treatment resulted in the metastatic tumors in the lung disappearing after 1 course. No severe adverse effects were observed. This combination chemotherapy proved useful for treating lung metastasis from gastric cancer in this patient.
