Filter by:The project objective is to evaluate the efficacy of the neoadjuvant treatment with bevacizumab, capecitabine and radiotherapy, in patients with rectal adenocarcinoma resectable locally advanced (stage T3 or T4), with or without presence of ganglionar metastases and without distant metastases.
This study is for patients with advanced or stage II and III colon or rectal cancer. The primary purpose of this research study is to determine if a particular protein in the patient's blood will change when they receive treatment with a drug called oxaliplatin, which is used to treat the colon or rectal cancer. This protein is called ERCC-1. It is thought that the amount of this protein in the blood could influence the manner in which the patient responds to oxaliplatin.
The purpose of this study is to determine the value of adding IMC-A12 to irinotecan and cetuximab in participants with metastatic colorectal cancer (CRC).
The purpose of this study is to determine whether markers on tumor tissue may be an indicator for good response to neoadjuvant chemoradiotherapy in patients with rectal cancer.
The addition of Oxaliplatin to conventionally fractionated chemoradiation (FULV or capecitabine) is considered as standard in unresectable rectal cancer by the panel of experts. The Investigators addressed the question whether short-course preoperative radiotherapy with consolidating chemotherapy of FOLFOX4 may increase the rate of R0 resection in patients with unresectable rectal cancer.
The primary objective of this study is to estimate the treatment effect on progression-free survival (PFS) of panitumumab relative to bevacizumab in combination with mFOLFOX6 chemotherapy as first-line therapy in patients with tumors expressing wild-type KRAS, unresectable mCRC.
At Tata Memorial Hospital 50% of the patients present in the locally advanced stage which is technically unresectable, or that is beyond the realm of a potentially curative surgical resection. The evaluation of treatment approaches for these tumors is hampered by the absence of any substantial randomized studies and the heterogeneous nature of the tumors at presentation. The management of these tumors has changed over the years, there is emphasis on neoadjuvant chemoradiation therapy, trying to convert a tumor that is initially unresectable to one that is potentially curable by surgery. But only 70-80% of the patients are able to complete this treatment without any significant treatment breaks. Dose escalated treatment with radiotherapy in locally advanced and unresectable rectal cancers have been tried in many small series with good results and lesser toxicity. Comparison outcome between the two arms will indicate the relative efficacy and toxicity of neoadjuvant concurrent chemoradiation vs boosted radiotherapy alone in downstaging of advanced cancers.
The purpose of this study is to evaluate the disease-free survival in patients with locally advanced rectal cancer treated with preoperative chemoradiotherapy with fluoropyrimidines and surgery followed by adjuvant combination chemotherapy with oxaliplatin/5-FU/Leucovorin vs 5-FU/Leucovorin.
Patients with oligometastatic colorectal cancer (5 metastases or less) receive a combination of systemic treatment and often local treatment, such as surgery, radiofrequency ablation and more recently stereotactic body radiotherapy. The aim of this study is to register the results and side effects of stereotactic body radiotherapy (SBRT) by means of helical tomotherapy in the treatment of oligometastatic colorectal cancer. The trial has two cohorts. Patients in cohort I get consolidation SBRT after best response on first line chemotherapy. Patients in cohort II get SBRT when there is progression under, or no indication for (further) chemotherapy. The primary endpoint is to evaluate the metabolic complete remission rate three months after the start of radiotherapy.
Primary Objectives To estimate the pathological complete response rate following neoadjuvant radiotherapy with concurrent capecitabine and oxaliplatin, with or without cetuximab based on the KRAS mutation status in rectal cancer. Secondary Objectives 1. To evaluate the incidence of grade 3-4 toxicities with each of the two neoadjuvant regimens and during the 30-day post-operative period. 2. To estimate the clinical tumour response rate and sphincter preservation rate with each of the two neoadjuvant regimens. 3. To correlate EGRF gene amplification with pathological response rate in those treated with cetuximab. 4. To estimate the pattern of failure. 5. To establish an annotated tissue library with samples being obtained prior to therapy and following therapy (at the time of surgery).
