RATIONALE: Drugs such as octreotide and loperamide hydrochloride use different ways to relieve the diarrhea caused by chemotherapy.
OBJECTIVES: I. Determine the safety and efficacy of octreotide acetate versus conventional therapy with loperamide hydrochloride for chemotherapy related diarrhea in patients with advanced colorectal malignancies undergoing chemotherapy with fluorouracil or fluorouracil based regimens.
OUTLINE: This is a prospective, randomized, parallel, open label, multicenter study. Patients are stratified by therapy, grade of diarrhea, and prior use of loperamide hydrochloride or octreotide acetate. Patients undergo 1 of 3 treatments. Patients receive either low doses of octreotide (arm A) or high doses of octreotide (arm B) subcutaneously 3 times daily for 5 days. Patients in arm C receive oral doses of loperamide following each unformed stool for 5 days. A diary is completed by patients to record medications and bowel history. Treatment continues if diarrhea persists beyond day 5, but will be considered a treatment failure. If diarrhea continues to worsen, patients are removed from study. All patients are followed for 24 days.
PROJECTED ACCRUAL: This study will accrue a total of 500 patients.
Allocation: Randomized, Primary Purpose: Supportive Care

The purpose of this study is to evaluate the efficacy of octreotide acetate to decrease GH and IGF-I levels in acromegalic patients, with microadenomas (≤ 10 mm) or macroadenomas (> 10 m...
This study will investigate the efficacy of a combination treatment with octreotide acetate and cabergoline in acromegalic patients that are only partially responsive to a somatostatin ana...
The present study will provide information on whether the somatostatin analog, octreotide acetate, could have an inhibitory effect on circulating chromogranin A. The demonstration of an an...
Determine the 6-month progression free survival (PFS) rate associated with IMC-A12 in combination with depot octreotide acetate (octreotide) in patients with metastatic neuroendocrine tumo...
Colorectal cancer is the third leading cause of cancer death among U.S. women. Women report being screened for colorectal cancer less often than men, and if colorectal cancer screening guidelines were...
Molecular aberrations in KRAS, NRAS, BRAF, and PIK3CA have been well-described in advanced colorectal cancer. The incidences of other mutations are less known. We report results of molecular profiling...
Abuse of the common anti-diarrheal loperamide is associated with QT interval prolongation as well as development of the potentially fatal arrhythmia torsades de pointes. The mechanism underlying this ...
Colorectal cancer, the second leading cause of cancer death in the United States, is also among the most preventable cancers. However, Latino men are less likely than non-Latino men to engage in preve...
P-glycoprotein (Pgp) is a multidrug resistance transporter that limits the penetration of a wide range of neurotherapeutics into the brain including opioids. The diphenylpropylamine opioids methadone ...
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Megestrol acetate is a progestogen with actions and uses similar to those of the progestogens in general. It also has anti-androgenic properties. It is given by mouth in the palliative treatment or as an adjunct to other therapy in endometrial carcinoma and in breast cancer. Megestrol acetate has been approved to treat anorexia and cachexia.
