Active clinical trials for "Rectal Neoplasms"

The objectives of this study are to: To assess dose-limiting toxicities (DLTs) of capecitabine +/- oxaliplatin in a combination regimen with capecitabine and radiotherapy (Phase 1) To determine the maximum-tolerated dose (MTD) when capecitabine oxaliplatin in a combination regimen with capecitabine and radiotherapy (Phase 1) To determine the pathologic response rate of cetuximab +/- oxaliplatin in combination with capecitabine and radiotherapy (Phase 2)

To demonstrate the effectiveness of epoetin alfa on reduction in red blood cell transfusions in gastric and rectal cancer patients undergoing preoperative chemoradiation therapy followed by surgery.

Standard treatment of rectal cancer is rectal excision with neoadjuvant radiochemotherapy. A new concept suggests organ preservation as an alternative to rectal excision in good responders after neoadjuvant radiochemotherapy to decrease surgical morbidity and increase quality of life. The rational is the fact that 15% of patients have sterilized tumours after radiochemotherapy for T3T4 rectal cancer. The French GRECCAR 2 trial is the first phase III trial investigating this strategy: patients with T2T3 low rectal carcinomas (size ≤4 cm) received 50 Gy with capecitabine and good clinical responders (≤2 cm) were randomized between local and rectal excision. The main findings were: the rate of complete pathologic response was higher after radiochemotherapy for small T2T3 than for T3T4 tumours (40% vs 15% ypT0) and good pathologic responders (ypT0-1) were associated with zero positive mesorectal nodes. The objective of the new trial is to increase the proportion of patients treated with organ preservation by optimizing tumour response. As compared to Folfiri, tritherapy Folfirinox has been shown to enhance the response rate. In patients with colorectal metastases, response rate and R0 resection were twice higher, resulting in improved survival. Folfirinox also increases response and chance of R0 resection rates in initially unresectable colorectal metastases, compared to standard or intensified bi-chemotherapy regimens. Adding two months of neoadjuvant chemotherapy (Folfirinox) before radiochemotherapy, the investigators expect to increase chance of organ preservation rate, as compared to radiochemotherapy alone.

This research trial studies genetic mutations in blood and tissue samples to see if they can be used to predict treatment response in patients with locally advanced rectal cancer undergoing chemoradiation. Studying samples of blood and tumor tissue in the laboratory from patients with cancer may help doctors learn more about genetic mutations or changes that occur in deoxyribonucleic acid (DNA) and help doctors understand how patients respond to treatment.

The purpose of this study is to compare the feasibility, safety, and quality of life (QOL) in patients (pts) undergoing protective ileostomy closure after 2 weeks with a closure after 12 weeks.

The aim of the present study is to investigate whether curative chemoradiation of low rectal cancer is feasible, safe and effective in a multicenter study with results comparable to those of single center studies. Results from previous studies indicate that a considerable fraction of patients with low rectal cancer can be cured by a combination of radiation and chemotherapy alone and thus be spared from operation.

The investigators start this prospective study to evaluate the efficacy of laparoscopic total mesorectal excision after concurrent chemo-radiation therapy with hyperthermia in locally advanced rectal cancer.

The primary goal of this Brown University Oncology Research Group is to determine that a safe dose of BYL719 can be administered with capecitabine and radiation in patients with rectal cancer. Therefore, the threshold of success for this phase I study is to establish safety.

The purpose of this research study is to evaluate the safety and feasibility of the Radial Reload Stapler during open LAR for rectal cancer. The surgeon will complete questionnaires relating to the function of the device.

The purpose of this adaptive trial is to compare the progression-free survival of participants with metastatic rectal carcinoma when treated with intravenous (IV) dalotuzumab (MK-0646) + irinotecan therapy relative to participants treated with IV cetuximab + irinotecan. The primary hypothesis is that administration of dalotuzumab in combination with irinotecan to participants with wild-type KRAS metastatic rectal carcinoma with high insulin growth factor (IGF)-1/low IGF-2 expression levels improves progression-free survival compared to patients treated with cetuximab in combination with irinotecan.
