Clostridioides difficile-related toxic megacolon after Cryptococcus neoformans cellulitis: A complex of two rare infections in an immunocompromised host.

A 76-year-old Japanese woman was admitted due to uncontrolled cellulitis of the right lower leg. She had deep vein thrombosis on the right limb. Moreover, she had a long history of rheumatoid arthritis treated with corticosteroids.

A randomized phase III trial exploring the prognostic value of extensive intraoperative peritoneal lavage in addition to standard treatment for resectable advanced gastric cancer: CCOG 1102 study.

A randomized controlled trial has started in Japan to evaluate the efficacy of extensive intraoperative peritoneal lavage in the treatment of resectable advanced gastric cancer. Patients with T3 or deeper carcinoma of the stomach are intraoperatively randomized to either extensive intraoperative peritoneal lavage + arm or extensive intraoperative peritoneal lavage- arm. A total of 300 patients will be accrued from 20 institutions.

The efficacy and safety of bevacizumab beyond first progression in patients treated with first-line mFOLFOX6 followed by second-line FOLFIRI in advanced colorectal cancer: a multicenter, single-arm, phase II trial (CCOG-0801).

Purpose: The aim of this study was to evaluate the efficacy and safety of the planned continuation of bevacizumab beyond first progression (BBP) in Japanese patients with metastatic colorectal cancer (mCRC).

Methods: Previously untreated patients with assessable disease were treated with mFOLFOX6 plus bevacizumab until tumor progression, followed by FOLFIRI plus bevacizumab. The primary endpoint of the study was the second progression-free survival (2nd PFS), defined as duration from enrollment until progression after the second-line therapy.

Multicenter phase II study of modified FOLFOX6 as neoadjuvant chemotherapy for patients with unresectable liver-only metastases from colorectal cancer in Japan: ROOF study.

Background: Neoadjuvant chemotherapy for unresectable colorectal liver metastases can reduce tumor size, which sometimes leads to curative resection. The aim of the present study was to identify and describe patients with initially unresectable liver-only metastases from colorectal cancer who obtained sufficient chemotherapeutic benefit that eventually lead to the removal of the metastatic diseases in the liver.

Methods: A phase II multicenter cooperative study was conducted in 38 medical institutions using modified FOLFOX6 (mFOLFOX6) as neoadjuvant chemotherapy from January 2008 to June 2009.

[Cetuximab-associated skin ulceration in patient with metastatic colorectal cancer: a case report].

An 82-year-old female was diagnosed with rectal cancer. Hartmann's procedure was performed and a curative resection was successfully achieved. Postoperative staging according to the classification of the Japanese Society for Cancer of the Colon and Rectum(The 7th Edition)was stage III.

[Elderly patient with recurrent rectal cancer successfully responded to modified FOLFOX6 chemotherapy with bevacizumab--a case report].

An 80-year-old female visited our hospital with the chief complaint of lower abdominal pain and diarrhea. She was diagnosed to have rectal cancer. Hartmann operation was performed and curative resection was successfully achieved.

The efficacy and toxicity of FOLFOX regimen (a combination of leucovorin and fluorouracil with oxaliplatin) as first-line treatment of metastatic colorectal cancer.

Background: Oxaliplatin is the third-generation platinum complex to be active in advanced colorectal cancer. In Japan, it was approved in April 2005. FOLFOX regimen(a combination of leucovorin and fluorouracil with oxaliplatin) has been one of the standard chemotherapy regimens for metastatic colorectal cancer.

[A case of advanced gastric cancer effectively treated with paclitaxel/S-1 as neoadjuvant chemotherapy].

We report a patient with advanced gastric cancer responding remarkably to neoadjuvant combination chemotherapy consisting of paclitaxel and S-1. The patient was a 65-year-old female who had large type 2 advanced gastric cancer with severe lymph node metastasis(cT3, cN3, cH0, cP0, cM0, cStage IV), treated with paclitaxel/S-1 as neoadjuvant chemotherapy. After the second course, according to UGI, gastroscope and CT findings, a significant tumor reduction was obtained.

Expression of CXCL12 and CXCR4 in pT3-stage gastric cancer does not correlate with peritoneal metastasis.

CXCR4, a chemokine receptor, is considered to be involved in the metastastic formation of various types of cancer and could influence survival. More recently, CXCR4 was reported to be associated with peritoneal metastasis in gastric cancer, and CXCL12, its ligand, as a prognostic determinant among gastric cancer of various stages. In order to more specifically delineate the relevance of CXCR4 in peritoneal metastasis, 98 patients with pT3-stage gastric cancer who underwent gastrectomy and detection of intra-abdominal free cancer cells in the peritoneal washing samples were evaluated.
