INTRODUCTION: Invasive micropapillary carcinoma (MC) is associated with frequent lymph node metastasis and adverse clinical outcome. It has been reported in ovary, breast, urinary bladder, ureter, lung, parotid gland and, recently, in colon. Little is known about the morphological and […]

Background: Irinotecan (CPT-11) is currently used as first- or second-line treatment for colorectal cancer, either alone or in combination with 5-fluorouracil based regimens. UDP-glucuronosyltransferase 1A1 (UGT1A1) catalyzes the inactivation of SN-38, the active metabolite of irinotecan, through glucuronidation. UGT1A1*28, a polymorphic variant of this enzyme displaying an additional TA dinucleotide in the promoter TATA box, has been […]

Chromosome 18q allelic loss has been reported to have prognostic significance in stage II colorectal carcinoma. We have developed a fluorescent multiplex polymerase chain reaction assay to analyze five microsatellite markers (D18S55, D18S58, D18S61, D18S64 and D18S69) for allelic loss determination at the long […]
