The electron density resolution is 1000 times higher for synchrotron-radiation phase-contrast CT imaging than conventional X-ray absorption imaging in light elements, with which high-resolution X-ray imaging of biological soft tissue can be achieved. In the present study, we used phase-contrast X-ray CT to investigate human resected esophagus and esophageal carcinoma specimens. This technology ...

Esophageal cancer incidence rates have been increasing over the past years and survival remain low. According to Global Cancer Observatory, 3.1% of new cases consists esophageal 5.5% deaths was due cancer. Histologic classification comprises either squamous cell carcinoma (SCC) or Adenocarcinoma. Other types are reported be uncommon. We present a case 33-year old male admitted progressive dysph...

Epidemiological studies suggest that the frequent intake of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a decreased risk of developing esophageal squamous cell carcinoma (SCC). This decrease is thought to correlate with the inhibition of cyclooxygenase (COX) activity. The production of prostaglandin E2 (PGE2), a major metabolite of COX, is increased in numerous human cance...

BACKGROUND The study aimed to evaluate the short- and long-term outcomes with a technique of self-expanding metallic stent insertion in palliative esophageal cancer patients. We hypothesized that a systematic attempt at exaggerated (5 cm) proximal tumor covering could prevent both stent migration and tumor overgrowth/undergrowth. METHODS We reviewed retrospectively all patients who underwent ...

PURPOSE Clinical target volumes (CTV) for radiotherapy (RT) in esophageal cancer (EC) are based on standard expansions of primary tumor volume. Data is needed to define regions at highest risk for occult disease, based on histology and location of the primary tumor. We therefore reviewed PET scans in EC patients to characterize the location of FDG-avid lymph node metastases (LNM). MATERIALS A...

Three cases of esophagectomy for secondary esophageal carcinoma metastasized from the ovary, breast and lung are reported. Long-term survival, 14 and 4 years, after esophagectomy was achieved in two patients. The intervals between surgery for primary cancer and dysphagia onset in these two patients were 16 and 7 years, respectively. An aggressive surgical approach appears to be the therapeutic ...

abstract background: esophageal anastomosis leaks continue to be a significant cause of morbidity and mortality after esophagectomy. the purpose of the present study was to identify the predisposing factors of esophageal anastomotic leakage. materials and methods: 95 patients who underwent surgical resection for esophageal or cardia cancer were included for the study. the mean age of the patien...

Common causes of right sided intra-cardiac atrial masses include primary cardiac tumors (atrial myxoma), atrial thrombus, tumor thrombus with hepatocellular or other thoracoabdominal cancers and metastatic lesions. Invasion of atria by gastrointestinal tumors is rare and that with esophageal ones seldom observed. Esophageal cancers rather present with dysphagia, odynophagia or systemic symptoms...

Esophageal schwannoma is a rare diagnosis and historically has been a tumor of middle-aged females. We report a case of a 22-year-old male presenting initially with dyspnea secondary to tracheal compression from an 8 × 6 × 3.0 cm esophageal schwannoma. The tumor was surgically resected, and diagnosis was confirmed with immunohistochemical and pathological studies. We report the youngest case of...

The purpose of this retrospective study was to clarify the predictive factors correlated with esophageal stenosis within three months after radiation therapy for locally advanced esophageal cancer. We enrolled 47 patients with advanced esophageal cancer with T2-4 and stage II-III who were treated with definitive radiation therapy and achieving complete response of primary lesion at Kyushu Unive...
