Filter by:Traditionally bowel preparation before surgery of rectal cancer could be troublesome for patients especially for patients with kidney and cardio- vascular diseases, where salt and electrolyte balance can be a problem. Cleaning the bowel without complications for the patient is one of the aims for this study. The other aim is to see if patient nutritional status improves with nutritional drinks as a complement to food intake 4-6 weeks before surgery.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying the side effects and how well giving oxaliplatin, capecitabine, and cetuximab together with radiation therapy followed by surgery works in treating patients with stage II or stage III rectal cancer.
Determine if genotype-directed neoadjuvant chemoradiation, using information from the thymidylate synthase promoter polymorphism, result in a greater degree of tumor downstaging in high risk patients compared to historical controls.
The purpose of this study is to investigate the safety and efficacy of simultaneous liver resections compared to staged hepatectomies of rectal cancer with liver metastasis and to compare the short and long-term survival between the two groups.
RATIONALE: Drugs used in chemotherapy, such as floxuridine and gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Hepatic arterial infusion uses a catheter to carry cancer-killing substances directly into the liver. Radiolabeled monoclonal antibodies can find tumor cells and carry tumor-killing substances to them without harming normal cells. Giving hepatic arterial infusion of floxuridine together with gemcitabine hydrochloride and radiolabeled monoclonal antibody therapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase I/II trial is studying the side effects and best dose of floxuridine when given as a hepatic arterial infusion together with gemcitabine hydrochloride and radiolabeled monoclonal antibody therapy and to see how well it works in treating liver metastases in patients with metastatic colorectal cancer.
The hypothesis of the present trial was that the use of a defunctioning loop stoma reduces the rate of symptomatic anastomotic leakage from 15% to 7.5% after low anterior resection of the rectum for cancer.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving these treatments 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. PURPOSE: This phase II trial is studying the side effects and how well giving combination chemotherapy together with intensity-modulated radiation therapy works in treating patients undergoing surgery for locally advanced rectal cancer.
The purpose of this study is to evaluate the efficacy of Udenafil (Zydena®, Dong-A Pharmaceutical co., Ltd, Seoul, Korea) in treatment of erectile dysfunction after radical resection for sigmoid colon and rectal cancer. In this study, the efficacy of Udenafil will be evaluated in treatment for patient with chronic erectile dysfunction, which developed after radical resection for sigmoid and rectal cancer and continues 12 months after the surgery.
Traditional transrectal ultrasound (TRUS) is a technique used to help determine the stage of rectal cancer. All patients at Memorial Sloan-Kettering Cancer Center with rectal cancer have an ultrasound at the beginning of their treatment to accurately determine the depth of penetration (how deep into the rectal wall the tumor goes) and lymph node involvement of their tumor. This information helps determine the best way to treat the patient's disease. Three-dimensional TRUS (3-D TRUS) is a new form of ultrasound that gives us all of the information of traditional ultrasound in addition to being able to view the tumor in 3-dimensions. This image can be stored and analyzed to evaluate the tumor size and volume as well as determine the unique shape of the tumor. Chemoradiotherapy before surgery is considered standard of care for most rectal cancers. Currently, there is no accurate way to determine whether or not the tumor has responded to the pre-operative radiation therapy. The purpose of this study is to evaluate the response of rectal cancer to pre-operative chemotherapy and/or radiation therapy using 3-D TRUS to measure the volume of the tumor before and after chemoradiotherapy.
The pilot study is designed to investigate the value of Neo-adjuvant Tomudez in combination with radiotherapy in patients with inoperable or recurrent rectal cancer in terms of response rate and increasing the resectability of initially inoperable rectal cancer.
