PURPOSE Histologic components of the TNM classification system have been repeatedly revised since the fifth edition (TNM5). TNM classification revisions provide different criteria for categorizing tumor nodules without residual lymph node structure (ND). However, there are few systematic evaluations regarding the effectiveness of these revisions. PATIENTS(More)
A 61-year-old male presented with a recurrent solitary fibrous tumor (SFT) arising from the falx cerebri with intraventricular extension manifesting as nausea and vomiting. Magnetic resonance imaging showed the heterogeneously enhanced tumor in the falx, which extended to the bilateral lateral ventricles and the third ventricle. Total tumor removal was(More)
A burned-out testicular tumor with lung and lymph node metastases presented high serum levels of DU-PAN-2. However, the serum levels of CA19-9, alpha-fetoprotein, beta-human chorionic gonadotropin, and sialyl Lewis X were normal. A biopsy of the cervical lymph nodes revealed embryonal carcinoma. Four courses of chemotherapy, including cisplatin, etoposide,(More)
We report a 32-year-old female patient with esophageal stricture thought to have been caused by hyperemesis gravidarum. Eleven months before admission she had been admitted to another hospital, because of hyperemesis gravidarum, at 26 weeks of gestation. Marked and recurrent vomiting occurred and her consciousness gradually worsened. Three weeks later, her(More)
A primary testicular carcinoid tumor with teratoma metastasized to the para-aortic lymph node. After inguinal orchiectomy, serum and urinary levels of 5-hydroxyindoleacetic acid (5-HIAA) were found to be elevated. Chemotherapy consisting of cisplatin, etoposide and bleomycin was not effective on the metastatic lesions. Retroperitoneal lymphadenectomy(More)
OBJECTIVE This study aimed to determine the optimal categorization of extramural tumor deposits lacking residual lymph node (LN) structure (EX) in colorectal cancer staging. BACKGROUND The TNM classification system categorizes EX on the basis of their contour characteristics (the contour rule). METHODS We conducted a multicenter, retrospective,(More)
The aim of this study was to clarify the histogenesis of Barrett's cancer. First, 28 lesions of the super-minute dysplasia <or= 1 mm in diameter were detected by pathological examinations for Barrett's esophagus. Secondly, the K-ras codon 12 mutations in these super-minute neoplasias of the Barrett's esophagus were examined by DNA extraction using a(More)
Aldo-keto reductase family 1, member B10 (AKR1B10), a cancer-related oxidoreductase, is expressed in well-differentiated hepatocellular carcinomas (HCCs). However, AKR1B10 levels are minimal in normal liver tissues (NLs), similar to the 70-kilodalton heat shock protein (HSP70) and glypican-3. Moreover, the role of AKR1B10 in chronic hepatitis or cirrhosis,(More)
Multiple granular cell tumors of the esophagus and the stomach found in a 53-year-old man are reported. One lesion was detected within the lower thoracic esophagus and seven lesions were detected in the stomach. The esophageal tumor was resected endoscopically, and gastrectomy was performed for the multiple gastric lesions. Histologically, the tumors(More)
BACKGROUND Although the gastric well-differentiated adenocarcinoma in the distal stomach has been thought to develop via a intestinal metaplasia-carcinoma sequence, there are some disproofs from new mucin examinations for minute-size lesions in same type carcinoma. The current study was performed and pointed out the new findings for the solution to the(More)
