Filter by:This pilot research trial studies telomere length in predicting toxicity in older patients with stage III-IV colorectal cancer undergoing chemotherapy. Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and predict how well patients will respond to treatment.
Background of the study: Colon cancer is the second leading cause of cancer-related death world wide. Although patients presenting with early disease (stage I-III) can be cured, prognosis varies from 90% in stage I to 50-80% in stage II and III. Therefore, prevention of metastases after early disease is of utmost importance. Derepression of Wnt targets may provide a novel target for therapy. Objectives: The primary objective of the study is to assess in patients with primary colon cancer whether short-course pre-operative treatment with decitabine can increase Wnt target gene expression as measured in resected tumors compared to pretreatment biopsies. The secondary objective of the study is to assess in patients with primary colon cancer whether short-course pre-operative treatment with decitabine can revert CpG methylation and induce more favorable tumor characteristics as measured in resected tumors compared to pretreatment biopsies. The tertiary objective is to compare changes in Wnt target gene expression, CpG methylation and tumor characteristics for Wnt methylated and nonmethylated tumors as measured in resected tumors compared to pretreatment biopsies and identify new stratification markers.
This phase II trial studies how well capecitabine and celecoxib with or without radiation therapy works in treating patients with colorectal cancer that is newly diagnosed or has been previously treated with fluorouracil, and has spread to other parts of the body (metastatic). Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving capecitabine and celecoxib together with radiation therapy may kill more tumor cells.
This phase II trial studies how well Polyphenon E works in treating patients with high-risk of colorectal cancer. Polyphenon E contains ingredients that may prevent or slow colorectal cancer.
The goal of this clinical study is to determine the dosing and safety of labetuzumab govitecan (formerly known as IMMU-130; hMN-14-SN38, antibody-drug conjugate) in participants with colorectal cancer.
The COMBATAC study evaluates the the effect as assessed by progression-free survival (PFS) of perioperative systemic chemotherapy including cetuximab and cytoreductive surgery (CRS) and bidirectional hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal carcinomatosis arising from colorectal cancer.
Preliminary studies with a variety of vaccines suggest target accessibility (potential immunogenicity) in a variety of solid tumors to immune directed approaches. In an effort to overcome limitations of immunostimulatory cancer vaccines, Gradalis has designed a novel autologous vaccine to address inability to fully identify cancer associated antigens, antigen recognition by the immune system (i.e. antigen-->immunogen), effector potency, and cancer-induced resistance. In an effort to overcome limitations of immunostimulatory cancer vaccines, we designed a novel dual-modulatory autologous whole cell vaccine, Vigil™, incorporating the rhGMCSF transgene and the bifunctional shRNAfurin (to block proprotein conversion to active TGFb1 and b2) to 1) address the inability to fully identify cancer associated antigens, 2) effect antigen recognition by the immune system, 3) enhance effector potency, and 4) subvert endogenous cancer-induced immune resistance. We have also completed the Phase I assessment of Vigil™ vaccine in 30 advanced solid tumor patients (1.0 x 10^7 cells/injection/month for a maximum of 12 vaccinations) who have not experienced any significant adverse effects following 144 vaccinations, including 6 patients with colorectal carcinoma. Plasmid functionality, immune biomarker response, and preliminary evidence of anticancer activity have been observed. This is a two-part Phase II study of the Vigil™ autologous vaccine. Six patients will be enrolled into the Part 1 of the study to receive intradermal autologous Vigil™ cancer vaccine (1.0 x 10^7 cells/injection; maximum of 12 vaccinations). Part 2 of the study will be a randomized Phase II study of sandwich or adjuvant chemotherapy and intradermal autologous Vigil™ cancer vaccine (1.0 x 10^7 cells/injection; maximum of 12 vaccinations) versus sandwich or adjuvant chemotherapy and placebo in patients with colorectal carcinoma with either synchronous or metachronous liver metastases (CLM +/= pulmonary metastases) following resection +/= ablation with curative intent.Sandwich therapy indicates a combination of both pre-operative and postoperative chemotherapy as opposed to neo-adjuvant (all chemotherapy prior to surgery) or adjuvant (all chemotherapy following surgery) therapy. A minimum harvest aliquot to produce 4 monthly injections will be required for entry into the study. Patients in whom insufficient tissue (<4 doses) is collected or whose vaccine fails manufacturing release criteria will not receive vaccine.
The purpose of this study is to determine the safety and efficacy of Thermodox, a thermally sensitive liposomal doxorubicin, in combination with thermal ablation in the treatment of hepatic colorectal liver metastases (CRLM).
The purpose of this study is to study the implementation of laparoscopy-assisted surgery for cure of colon cancer in daily surgical practice.
RATIONALE: Drugs used in chemotherapy, such as irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or stopping them from dividing. Chemoembolization kills tumor cells by blocking blood flow to the tumor and keeping chemotherapy drugs near the tumor. PURPOSE: This phase II trial is studying how well chemoembolization using irinotecan works in treating patients with liver metastases from metastatic colon or rectal cancer.
