The cellular composition of the human milky spots was investigated on surgically removed specimens of the greater omentum of three 8-month-old infants operated on for neuroblastoma. Monoclonal antibodies and immunohistochemical methods for recognition of macrophages. B-lymphocytes and T-lymphocytes and toluidine-blue staining for mast cells were used. The(More)
A novel method of prophylaxis and treatment for peritoneal carcinomatosis--mitomycin C bound to activated carbon particles (MMC-CH)--was tested in patients with advanced gastric cancer in a prospective randomized study. Activated carbon particles are taken up selectively by lymphatic tissues, which seem to be a primary site of peritoneal carcinomatosis in(More)
We examined the site-specific implantation of cancer cells in peritoneal tissues after an i.p. inoculation of 10(5) P388 leukemia cells. Twenty-four h after the inoculation, the number of viable cancer cells infiltrating into specific tissue sites of the peritoneum was estimated by an i.p. transfer method. A descending order of tissue implantation with(More)
We investigated the significance of milky spots for malignant cells in peritoneal dissemination using three mouse carcinomatous peritonitis models. P388 leukemia and Colon 26 cancer cells were labeled with bromodeoxyuridine (BrdU) and mice were inoculated intraperitoneally. After 24 h the greater omentum and the mesenterium were removed and stained(More)
Surgical practice for gastric cancer in Japan is based on the Gastric Cancer Treatment Guidelines issued in 2001 by the Japanese Gastric Cancer Association. These recommendations list options for treatment of each stage of cancer, with clear distinctions between interventions recommended for routine use and those that should be confined to trial settings(More)
To investigate the site-specific implantation of cancer cells in peritoneal dissemination, we inoculated CDF1 mice intraperitoneally with mouse P388 leukaemia cells labelled with bromodeoxyuridine (BrdU) and then observed immunohistochemically the distribution of the cells in the greater omentum taken from the mice using an anti-BrdU antibody. We found the(More)
CH40 and CH1500AA are newly prepared carbon suspensions which were examined as vital staining dyes for their usefulness in visualizing lymphatics at operation and to blacken lymph nodes. In mice, these carbon suspensions at 0.001 ml/g of body weight and India ink were injected subcutaneously into the footpad of the right hindpaw. Regional lymph nodes were(More)
4222 Background: On the basis of our preliminary study of a combination of weekly paclitaxel (PTX) and DPD-inhibitory oral fluoropyrimidines (UFT, S-1) in advanced or recurrent gastric cancer (ARGC), we devised and started a phase I trial of a combination of S-1 and weekly PTX in ARGC. Objectives of the present trial were to examine dose-limiting toxicities(More)
