Filter by:RATIONALE: Sunitinib malate 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. Drugs used in chemotherapy, such as irinotecan hydrochloride, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with sunitinib malate may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving sunitinib malate together with combination chemotherapy works as front-line therapy in treating patients with metastatic rectal cancer that cannot be removed by surgery.

Product: Product 1: BB536 and LA1 (10E9) Product 2: BB536 and LA1 (10E7) Placebo: Maltodextrin Number of patients: enrolled subjects: n=33, ITT data set: n=31, PP data set: n=30 Primary objective: Colonization (biopsy+stools) of each bacteria for one of the dose at D0 (surgical procedure) Secondary objectives: - Influence of the probiotic bacteria on the gut microflora - Modulation of the immune and inflammatory response Additional objectives: - Investigate dose effect on La1 colonization - Investigate the effect of La1 colonization, treatment without La1 colonization, and absence of treatment and La1 colonization on other bacteria and on immunological parameters
The investigators are involved in a research program to understand how different diets may affect the risk of colorectal polyps and cancer. To that end, the investigators are conducting a study of a western style diet versus a "prudent style" diet in which volunteer subjects are provided a different diet for 2 separate 4 week periods at the Rockefeller University Hospital. During one of these 4 week inpatient periods they receive a Western style diet and during the other 4 week inpatient period they receive a "Prudent style" diet. The investigators will determine changes within the colon as a result of the two different diets. A more detailed description of the study is provided below.
Contribution to the study of oxidative stress markers in laparoscopic vs open colectomy for colorectal cancer
Colorectal cancer (CRC) is the second leading cause of cancer in Puerto Rico (PR) accounting for approximately 1,500 individuals annually, which represent 12% of all cancer cases in the island. The genetic epidemiology of CRC among Hispanic populations is not well studied, hence studies focused on large, well defined ethnic groups such as Puerto Ricans, are clearly warranted. The first step towards evaluating the molecular, environmental, and genetic epidemiology of CRC in PR is to establish a population-based familial CRC registry. The following specific aims have been proposed: Specific Aim 1: To prospectively identify and recruit approximately 300 CRC probands from two distinct geographical areas in PR (Metropolitan and Southern Region). From each proband the investigators will obtain a pedigree extended to second-degree relatives and cousins. Assuming 10% will be positive for a family history of CRC, the investigators will then recruit all 30 probands with a family history of CRC and a sample of 15 family-history negative probands and obtain: paraffin-embedded tumors blocks, blood samples, risk factor and food frequency questionnaires. Specific Aim 2: To prospectively identify and recruit selected relatives (parents, grandparents, and same generation relatives - cousins and siblings) from the 45 probands identified in Specific Aim 1. In addition, for siblings and cousins of probands (i.e. relatives in the same generation as the proband), the investigators will obtain risk factor and food frequency questionnaires, and for colorectal cancer cases, tumor blocks and pathology reports of their cancers. Specific Aim 3: To estimate from this pilot study the following parameters: (a) response rate of probands and their selected relatives; (b) response rate of participants for each data item; (c) family history of CRC and other cancers; (d) number of living first- and second-degree relatives and cousins of probands; (e) number of these relatives who live in the same household and region/municipality; (f) prevalence/distribution of selected risk factors from the administered questionnaires.
The purposes of this study were to assess the safety, tolerability, pharmacokinetic interactions, and the Human Anti-Human Antibody of dalotuzumab in combination with cetuximab and irinotecan in participants with advanced or metastatic colorectal cancer in Japan.
The goal of this research study is to design messages which can help people learn more about how to prevent colon cancer. Eligible participants will be asked to review a series of short cancer prevention messages and share their opinions on them. Participants also need to fill out a short survey with questions on their background and attitudes and knowledge about physical activity and colon cancer. The whole study can be completed online and will take less than 1 hour. After completing the entire study, participants will receive $25.

Objectives: - To find out the maximum tolerated dose of the GI-6207 vaccine (the highest dose that does not cause unacceptable side effects), and to evaluate any side effects. - To see if GI-6207 has any effect on patients tumors. - To learn how the vaccine causes immune responses against the cancer. Eligibility: - Patients 18 years of age and older who have been diagnosed with a cancer that has not responded to standard treatments. Patients must not be allergic to yeast or yeast products. Design: - Initial physical examination, blood and tissue sampling, computed tomography (CT) scan, and skin test to determine eligibility for the procedure. - Treatment with GI-6027 in seven 14-day cycles as follows: - Vaccine administered on days 1, 15, 29, 43, 57, 71, and 85. - Vaccine given at four sites around the body: right and left chest area below the armpit, and right and left upper thigh in the pelvic region. (These areas drain into parts of your body that contain large numbers of lymph nodes. The lymph nodes contain immune cells that may be activated by the vaccine to target cancer cells.) - Clinic visits for physical examinations to check vital signs, take additional blood and urine samples, and perform other tests needed for the study. - After day 85 (about 3 months), patients will continue to receive vaccine monthly (or every 28 days) as long as the vaccine is not producing harmful effects or side effects and the cancer is either stable or reducing. Patients who do well on the vaccine may continue to receive it for as long as it is available.
Background: - Researchers are trying to learn what causes certain types of cancer to spread to other organs in the body (metastasis). Cancer tumors may produce a very small number of specific cells (cancer stem cells) that cause the tumors to grow in other organs throughout the body. - By examining cancer tumor tissue, normal tissue, blood, bone marrow, and other body fluids, researchers may determine whether these samples contain cancer stem cells. Cancer stem cells may provide information on whether the cancer will come back or spread before other routine x-ray studies or lab tests indicate its presence. Objectives: - To acquire a collection of solid organ cancer stem cells for future study. - To analyze solid organ cancer stem cells from various types of cancer on a genetic level. - To determine if solid organ cancer stem cells are present in the blood or bone marrow. Eligibility: - Patients 16 years of age and older who have solid organ cancer (cancer in the liver, colon, rectum, anus, pancreas, stomach, breast, skin, muscles, fat, connective tissue, uterus, ovary, cervix, vagina, vulva, or inner lining of the abdomen) or a precancerous growth, and who are scheduled to have a biopsy or surgery to remove the cancer as part of their treatment. Design: - This is a prospective trial designed to procure solid organ cancer stem cells before either surgery or biopsy. - All patients registered to this trial will undergo surgery to extirpate their cancer in the NCI - Prior to surgery or biopsy, 8 tablespoons of blood will be drawn. - During the surgery or biopsy, a sample of normal tissue will be removed along with the cancerous or precancerous tissue. If separate consent is given, samples of bone marrow will also be taken. - After discharge, patients will return to the clinic for routine visits every month for the first 3 months following surgery, and then about every 3 months for 2 years, and then every 6 months for 3 years. During the visits, patients will have routine blood and imaging studies done, and researchers will take additional blood samples (about 8 tablespoons at each visit) and optional bone marrow samples (4 teaspoons every 6 months) to be used for research.
RATIONALE: Studying samples of tumor tissue in the laboratory from patients with cancer who have undergone surgery and chemotherapy may help doctors predict how well patients will respond to treatment. PURPOSE: This research study is looking at tumor samples from patients with stage III colon cancer who have undergone surgery and chemotherapy.
