[Peritoneal Mesothelioma Diagnosed with a Sister Mary Joseph's Nodule].

In August 2022, a 59-year-old female noted a mass in her umbilicus and sought evaluation at Toyokawa City Hospital. Abdominal computed tomography(CT)scan revealed a 1.6 cm mass in the umbilical region, ascites in the pelvis, and increased absorption in the omentum.

[A Case of Rectal Cancer with Lymph Node Metastasis Diagnosed as Intramucosal Cancer].

The patient was a 62-year-old man in whom 0-Ⅱa plus Ⅱc lesions in Rs were identified during follow-up observation of multiple colorectal polyps that were found during colonoscopy performed for the examination of fecal occult blood. CT showed no lymphadenopathy or distant metastasis to other organs. Laparoscopic-assisted high anterior resection of the rectum was performed with a diagnosis of clinical stage Ⅰ.

[A Case of Colostomy-Free and Long-Term Survival with 5-FU/CDDP for Local Recurrence of Anal Cancer after Chemoradiation Therapy].

We report a case of colostomy-free, long-term survival following 5-FU/CDDP for the local recurrence of anal cancer after chemoradiation therapy(CRT). The patient was a 48-year-old woman who was diagnosed with cStage ⅢA anal cancer. She was treated with CRT(5-FU/MMC plus 59 Gy)and achieved a complete response upon treatment completion.

[A Case of Resected Pancreatic Metastasis of Rectal Cancer after Multiple Resections of Metastatic Lesions].

A 71-year-old man underwent low anterior resection for rectal cancer 10 years prior. He underwent resection of liver metastasis once and that of lung metastases multiple times after the primary surgery. Computed tomography revealed a mass measuring 22mm in size in the pancreatic body 10 years after the rectal resection.

Phosphoinositide 3-kinase inhibitor (wortmannin) inhibits pancreatic cancer cell motility and migration induced by hyaluronan in vitro and peritoneal metastasis in vivo.

In order to block peritoneal metastasis of pancreatic cancer cells, we have attempted to block the signal transduction pathway involving hyaluronan (HA), Src, phosphoinositide 3-kinase (PI3K) and Akt. We examined the effects of Src, PI3K and Akt inhibitors on pancreatic cancer cell motility, invasion and metastasis. The pancreatic cancer cell line SW1990, known to cause peritoneal metastasis efficiently in nude mice, was used in this study.

Calpain is involved in the HIV replication from the latently infected OM10.1 cells.

Treatment of OM10.1 cells latently infected with human immunodeficiency virus type 1 (HIV-1) with phorbol ester and calcium ionophore (A23187) induced virus replication which was blocked by N-Ac-Leu-Leu-norleucinal (ALLnL), a calpain inhibitor I, and not by lactacystin, a specific proteasome inhibitor. When the purified NF-kappa B/I kappa B complex was treated with mu-calpain, the specific DNA-binding activity was demonstrated by using electrophoretic mobility shift assay in vitro.

[Efficacy of intraperitoneal chemotherapy for advanced Borrmann type IV gastric carcinoma].

We report four patients with advanced Borrmann type IV gastric carcinoma, in whom intraperitoneal chemotherapy with low-dose CDDP and 5-FU plus MMC via a peritoneal port was effective against peritoneal metastasis. However, none of the four patients survived for a long period. During treatment, they were followed on an outpatient basis and received intraperitoneal chemotherapy biweekly with good control of peritoneal metastasis.

Solitary intraperitoneal recurrence of alpha-fetoprotein-producing gastric carcinoma: report of a case.

A solitary recurrence of gastric carcinoma in the peritoneal cavity is extremely rare. We herein present a case of solitary intraperitoneal recurrence in a patient with alpha-fetoprotein (AFP)-producing gastric carcinoma. As far as we can determine, this is the first report of such a form of recurrence in a patient with gastric carcinoma who underwent a successful resection.
