[Switching to direct intrahepatic arterial infusion of 5-FU after a progression of liver metastases from colorectal carcinoma treated with systemic infusion of FOLFOX].

Direct intrahepatic arterial infusion of 5-FU produced a significantly higher response rate than systemic infusion of FOLFOX in the treatment of hepatic metastases from colorectal carcinoma. Fourteen patients switched over from systemic FOLFOX therapy to intrahepatic protracted 5-FU infusion after a progression of liver metastases treated with systemic therapy. Of the 14 patients whose tumors had initially failed to respond to systemic FOLFOX therapy, 12 (85%) had a partial response, and 13 (93%) had a reduction in their tumor marker (CEA, CA19-9, TPA) when the treatment was switched to intrahepatic 5-FU therapy.

Basal cytokeratin expression in relation to biological factors in breast cancer.

The objective of this study was to determine the predictive impact of several established tumor biological markers and clinicopathological findings for basal-like carcinoma. Expression was determined by immunohistochemistry using antibodies to cytokeratins 5/6, 14, and 17, and the cases were divided into basal-like carcinoma and non basal-like carcinoma. These subgroups were compared in terms of biological markers (HER2, estrogen receptor, progesterone receptor, Ki-67, P-53, and P-glycoprotein) and clinicopathological behavior.

MK-801 inhibits the micturition reflex in chronic bladder irritation caused by crystalluria in the rat.

Urodynamic and pharmacological studies were performed to investigate the effect of crystalluria on the micturition reflex and the involvement of glutamatergic transmission. The rats, which were given LP-805 (100 mg/kg/day) orally for 12 days, voided crystalluria. The pH of these crystalluria (LP-805 urine) was the same as normal urine.
