Mesenteric Myxofibrosarcoma: A Case Report.

Myxofibrosarcoma is a soft tissue sarcoma that occurs in elderly patients. Primary myxofibrosarcoma rarely arises in the mesentery; this is the fourth known case of myxofibrosarcoma presenting as a mesenteric tumor. A 62-year-old male with a mesenteric myxofibrosarcoma presented with an abdominal mass; his symptoms were frequent urination and a sense of abdominal pressure.

Mixed ductal-acinar cell carcinoma of the pancreas: A case report.

Mixed carcinoma of the pancreas is defined as the concurrent existence of pancreatic ductal carcinoma, acinar cell carcinoma, and/or islet cell carcinoma within the same neoplasm. We herein report a rare case of mixed ductal-acinar cell carcinoma in a 74-year-old man who was undergoing treatment for hypertension and diabetes at another hospital. After an abrupt worsening of his blood glucose control, the patient was referred to our hospital for further evaluation.

[Endocrine cell carcinoma of the esophagus without recurrence for more than 7 years after chemoradiotherapy].

We report a case of endocrine cell carcinoma (ECC) of the esophagus with long term survival after chemoradiotherapy. The patient had a complete response and remains without any recurrence. A 69-year-old woman visited our hospital because of progressive dysphagia.

Successful Resection of a Large Rectal Adenoma Using the Transsacral Approach.

The transsacral approach is not routinely used for treating rectal tumors. We report the case of a 65-year-old man with a large adenoma at the posterior wall of the mid-rectum who was treated via the transsacral approach. The same lesion had been treated using transsacral endoscopic microsurgery 8 years previously.

Fecoflowmetric analysis of anorectal motor function in postoperative anal-preserving surgery patients with low rectal cancer comparison with the wexner score and anorectal manometry.

The aim of this study was to elucidate whether fecoflowmetry (FFM) could evaluate more detailed evacuative function than anorectal manometry by comparing between FFM or anorectal manometric findings and the clinical questionnaires and the types of surgical procedure in the patients who received anal-preserving surgery. Fifty-three patients who underwent anal-preserving surgery for low rectal cancer were enrolled. The relationships between FFM or the manometric findings and the clinical questionnaires and the types of procedure of anal-preserving surgery were evaluated.

Expression of monocarboxylate transporter (MCT)-4 in colorectal cancer and its role: MCT4 contributes to the growth of colorectal cancer with vascular endothelial growth factor.

Background: In tumor cells, monocarboxylate transporter (MCT)-4 regulates the excretion of lactate produced by glycolysis from the cell. MCT4 has also been reported to be involved in tumor growth and infiltration. Similarly, vascular endothelial growth factor (VEGF) is known to be involved in the growth, infiltration, and metastasis of tumors.

Gemcitabine with paclitaxel therapy against mesocolic leiomyosarcoma: a case report.

A 65-year-old man complained of lower right abdominal pain, and an intra-abdominal mass was identified. An intra-abdominal hemorrhage was discovered during a thorough examination and emergency surgery was performed. The tumor was ruptured and was fragile, making it difficult to perform extirpation; thus, an ileocecal resection was performed.

Clinicopathological study on poorly differentiated adenocarcinoma of the colon.

Clinicopathological characteristics and grading of poorly differentiated colon adenocarcinoma (Por) were discussed. A total of 1074 patients with colon cancer underwent surgical treatment at Kurume University Hospital in Fukuoka, between 1985 and 2005. Clinicopathological characteristics of 88 cases (8%) of Por and 986 cases (92%) of well differentiated tubular adenocarcinoma/moderately differentiated tubular adenocarcinoma (Tub1/Tub2) were studied.

Challenges in staging systems for colorectal cancer: clinical significance of metastatic lymph node number in colorectal cancer and mesorectal extension in rectal cancer.

In many countries, treatment for cancer is performed based on staging systems in which the degree of cancer development is defined objectively. A common staging system is thus needed to compare outcomes. The staging system for colorectal cancer in Japan has been made to enhance consistency with the TNM classification, and the categorization of metastatic lymph nodes and depth of invasion have been revised in recent years.
