We report on a case of human epidermal growth factor receptor-2 (HER2)-positive gastric cancer with paraaortic lymph node metastasis. The patient (a 49-year-old female) received chemotherapy (capecitabine and cisplatin) plus molecular-targeted therapy (trastuzumab), followed by curative resection. Interestingly, the resected residual cancer was(More)
BACKGROUND Although esophagectomy with extended lymph node dissection can improve survival of patients with esophageal carcinoma, lymph node metastasis has remained one of the main recurrence patterns. The aim of this study was to evaluate the outcome of intensive treatment for recurrent lymph node metastasis. METHODS Recurrent lymph node metastasis was(More)
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)
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)
The aim of this study was to confirm that the emphysematous changes had increased in the remaining lung on the operation side after lobectomy. Fourteen patients underwent quantitative analysis by computed tomography (CT) and respiratory function testing before and after the operation for upper or lower lobectomy of the lung between March 2005 and May 2007.(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)
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)
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)
An 81-year-old woman presented with left hypochondrial pain and vomiting. CT showed incarceration of the entire stomach in the left pleural cavity with esophageal hiatus hernia with mesenteroaxial gastric volvulus. We diagnosed upside down stomach. Upper gastrointestinal endoscopy showed no impairment of blood supply to the gastric mucosa and she had(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)
