OBJECTIVE In order to assess the usefulness of esophagectomy through mini-thoracotomy/laparotomy as a minimally invasive surgical procedure for esophageal cancer, we compared the results to those of conventional right thoracotomy/laparotomy. METHODS From 1998 to 2002, 40 patients with thoracic esophageal cancer were prospectively assigned to two groups.(More)
BACKGROUND/AIMS The aim of this study was to assess the outcome of salvage esophagectomy with less extensive lymphadenectomy, which we have performed since 2003 to improve high mortality and morbidity of standard salvage esophagectomy. METHODOLOGY We retrospectively compared the surgical outcome of 15 patients who underwent standard salvage esophagectomy(More)
We conducted a pilot study of nedaplatin + 5-fluorouracil (5-FU) combined with radiotherapy for 29 patients with primary advanced (stage IV) esophageal cancer. A complete remission (CR) was obtained in 4 (14%) and a partial response in 13 patients (response rate: 59%). The median survival time and one-year survival rate were 238 days and 34.5%,(More)
Primary esophageal mucosa-associated lymphoid tissue (MALT) lymphoma is rare. There have been few reports about early primary esophageal MALT lymphoma being treated endoscopically. The clinical profile of primary esophageal MALT lymphoma is currently unclear, so it is important to accumulate more information about early esophageal MALT lymphoma. To achieve(More)
Although chemotherapy consisting of cisplatin and 5-fluorouracil(CF)has been a standard regimen for esophageal cancer, it might be difficult to use continuously. This study evaluated the response and safety of docetaxel plus S-1 used as a second line therapy. We reviewed 21 patients(postoperatively, 11; after definitive chemoradiotherapy, 8; after(More)
A 69-year-old man presented with epigastralgia at a local hospital. Endoscopy detected a superficial esophageal carcinoma arising from a mid-esophageal diverticulum with intraepithelial spread. The patient was referred to our hospital for further examination and treatment. Esophagography showed irregularity in the mid-esophageal diverticulum. Endoscopic(More)
BACKGROUND Patients with esophageal achalasia are considered to be a high-risk group for esophageal carcinoma, and it has been reported that this cancer often arises at a long interval after surgery for achalasia. However, it is unclear whether esophageal carcinoma is frequent when achalasia has been treated successfully and the patient is without(More)
Background and study aims: A standard treatment for esophageal squamous cell carcinoma (SCC) with submucosal invasion is considered to be radical resection at present. In this study, we evaluated the efficacy of multimodality treatments with endoscopic mucosal resection (EMR) of esophageal SCC with submucosal invasion. Method: Eighteen cases of SCC with(More)
Definitive chemoradiotherapy has been performed as a first-line treatment for esophageal cancer, whereas salvage surgery might be the only reliable treatment for patients with recurrence after definitive chemoradiotherapy. We reviewed 38 patients with squamous cell carcinoma who underwent esophagectomy and 6 patients who underwent lymphadenectomy after(More)
The histology of esophageal cancer represents squamous cell carcinoma mainly in Eastern countries and adenocarcinoma in Western countries. This difference entails differences in treatment strategy. Thus, clinical studies in Japan are necessary, although recent trials showed marvelous progress. By adopting pharmacogenetic approaches for not only biomarkers(More)
