Filter by:This phase II trial is studying how well giving sorafenib together with bevacizumab works in treating patients with metastatic colorectal cancer. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Sorafenib and bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving sorafenib together with bevacizumab may kill more tumor cells
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.
Hypothesis - Pre operative radio-chemotherapy might be not mandatory to improve local recurrent rate and survival rate in the mid-lower rectal cancer patients with T3N0 clinical stage, if surgical principals were kept. - Laparoscopic resection is not inferior to Open surgery in the treatment of rectal cancer.
The primary objective of this study is to evaluate the safety and efficacy of Irinotecan Bead in combination with intravenous chemotherapy versus intravenous chemotherapy alone in the treatment of unresectable liver metastases in patients with colorectal cancer. The results of this study are intended to be used in support of a PMA application for a combination device
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.
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).
To determine whether biomarkers assessed in blood samples can be used to detect individuals at risk for developing blood clots or worsening of their underlying disease. The ultimate goal of the study is to identify key biomarkers derived from blood that are most characteristic and informative of individuals who will go on to develop a clotting complication.
RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy that uses a 3-dimensional image of the tumor to help focus thin beams of radiation directly on the tumor may kill more tumor cells and have fewer side effects. Giving chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether capecitabine is more effective with or without oxaliplatin in treating patients with rectal cancer. PURPOSE: This randomized phase III trial is studying giving chemotherapy together with radiation therapy before surgery followed by capecitabine with or without oxaliplatin to see how well it works in treating patients with locally advanced rectal cancer.
This randomized phase II trial is studying how well erlotinib hydrochloride works in treating patients with stage I-III colorectal cancer or adenoma. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Erlotinib hydrochloride may also stop tumors from growing or coming back
