Active clinical trials for "Rectal Neoplasms"

This study will evaluate whether the addition of Rosuvastatin to standard chemoradiation therapy for the treatment of locally advanced rectal cancer may improve the pathological response rate and survival compared to standard chemoradiation therapy alone.

Radiotherapy (RT) is a potentially effective method in the treatment of symptoms of rectal carcinomas. Nevertheless, almost all the evidences about palliative RT in rectal cancer have been published more than two decades ago and were based on 2D conventional RT, which is nowadays no longer used. Consequently, prospective studies on the efficacy of 3D-RT in the management of symptomatic rectal cancer are still lacking. The aim of this prospective study was to assess the efficacy of palliative short-course 3D RT (SCRT) in patients with symptomatic obstructive rectal cancer.

Patients with locally advanced rectal or rectosigmoid cancer staged cT3 CRM-negative with MRI will receive 6 cycles of neoadjuvant treatment with mFOLFOX6 (Arm A) vs. mFOLFOX6 + aflibercept (Arm B) followed by surgery.

The purpose of this study is to evaluate the safety and efficacy of CT guided 125I seeds implant plus systemic chemotherapy for locally recurrent rectum cancer.

Metformin is an oral antidiabetic of the biguanide class derived from galega officinalis. Historical cohort of patients with diabetes have shown that diabetics on Metformin had a better chance of survival than diabetics not on Metformin. These observations have led to in vitro studies of metformin on cancer cells. It was thus demonstrated that Metformin has anti-proliferative properties. The aim of our study is to evaluate the efficacy of metformin in combination with neoadjuvant radiochemotherapy in the treatment of locally advanced rectal cancer.

This study aims to investigate the feasibility, safety and efficacy of triplet regimen of neoadjuvant chemotherapy in patients with locally advanced rectal cancer

Neoadjuvant chemoradiation (CRT), is considered the standard treatment of locally advanced rectal cancer with a positive impact on locoregional control and survival.However, patients with T4 rectal cancer show high risk of local recurrence after conventional treatment. Therefore investigators designed a prospective Phase II study on patients with locally advanced rectal cancer or locally recurrences, to evaluate the efficacy in terms of pathological response and resectability of concomitant boost RT (55 Gy/5 weeks) with concurrent Raltitrexed and Oxaliplatin (Tom-Ox) chemotherapy.

Patients will be randomized (1:1 ratio) to receive either 4 weeks of Ondansetron followed by 4 weeks of placebo (O-P sequence) or 4 weeks of placebo followed by 4 weeks of Ondansetron (P-O sequence). It will be one week of washout between the two treatments. During the treatment questionnaires will be completed by the patients to evaluate the efficacy of the study treatment and the quality of live.

This phase I clinical trial is studying the side effects and best dose of giving gamma-secretase inhibitor RO4929097 and cediranib maleate together in treating patients with advanced solid tumors. Gamma-secretase inhibitor RO4929097 and cediranib maleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cediranib maleate also may stop the growth of tumor cells by blocking blood flow to the tumor.

Phase II clinical trial, open-label, randomized, two arms, multicentre (possibly multinational). Academic, investigator initiated. To assess the activity of bevacizumab (AvastinTM) in combination with capecitabine (XelodaTM) and radiation therapy with or without oxaliplatin (EloxatinTM) in the pre-operative treatment of locally advanced rectal cancer, followed by TME (total mesorectal excision).
