S100P, a calcium-binding protein, is preferentially associated with the growth of polypoid tumors in colorectal cancer.

Colorectal cancer (CRC) is a genetically heterogeneous disease with distinct morphological patterns. It has been shown that polypoid and ulcerative CRC displays different genetic alterations. In the present study, we aimed to investigate genes with differential expression patterns between ulcerative and polypoid CRC.

Oxaliplatin with weekly bolus 5-fluorouracil and leucovorin in pretreated advanced colorectal cancer patients: a phase II study.

Background: The purpose of this study was to determine the efficacy and toxicity of oxaliplatin in combination with weekly bolus 5-fluorouracil (5-FU) and leucovorin (LV) in patients with 5-FU-pretreated advanced colorectal cancer.

Methods: A total of 39 patients with documented 5-FU-resistant advanced colorectal cancer were enrolled. All 39 patients had previously received weekly high-dose 5-FU/LV (2,600 mg/m(2) 5-FU plus 100 mg/m(2) LV as 24-hour infusion) as first-line chemotherapy for metastatic disease.

Biweekly bolus 5-fluorouracil and leucovorin plus oxaliplatin in pretreated patients with advanced colorectal cancer: a dose-finding study.

The primary objective of this study was to determine the maximum tolerable dose (MTD) and dose-limiting toxicity (DLT) for bolus 5-fluorouracil (5-FU) administered on a biweekly schedule and in combination with fixed doses of leucovorin (LV) and oxaliplatin. The secondary objectives were to evaluate the toxicity profile and antitumor activity of this regimen for pre-treated patients with advanced colorectal cancer. A total of 26 patients with documented fluoropyrimidine-resistant, advanced colorectal cancer were enrolled into this phase I study.
