Colorectal Cancer

The world’s population is aging. Older age is associated with an increase in the incidence of cancer, especially cancer of the breast, lung, prostate, and colon. The management of older patients with cancer is biased by the

BOSTON-HIV-positive patients often cannot tolerate treatment for anal squamous cell carcinoma and have a worse prognosis than other patients, according to two studies presented at the American Society of Colon and Rectal Surgeons (ASCRS) annual meeting.

Capecitabine (Xeloda) is a new, orally administered, enzyme-activated fluoropyrimidine carbamate designed to generate high levels of fluorouracil (5-FU) in tumor cells. Selective tumor activation of 5´-deoxy-5-fluorouridine,

FLINT, Michigan-The debate continues on the use of sentinel lymph node (SLN) mapping in colon cancer. How many nodes need to be analyzed to improve the outcome for this patient group? The current thought is the more nodes harvested, the better the predictive value, and Dr. Thomas LeVoyer made the case that removing more nodes yields a better survival benefit.

PHILADELPHIA-Nearly 45% of all cases of colon cancer have lymph node involvement. Surgical resection is the gold standard of treatment, with adjuvant chemotherapy used in an attempt to improve survival in patients with late-stage disease, but the outlook is often dismal.

NEDLANDS, Australia-If the implications of an Australian study are validated in further prospective studies, microsatellite instability (MSI) could potentially predict those patients with Dukes’ C and possibly Dukes’ B colorectal cancer who will respond best to chemotherapy.

NEW ORLEANS-A prospective study in colorectal cancer patients has found that sentinel lymph node (SLN) mapping correctly predicts the presence or absence of nodal metastases, with a very low incidence of skip metastases (disease in a non-SLN), as it does in melanoma and breast cancer.

Microsatellite Instability Linked to Longer Colon Cancer Survival

Either alone or in combination with other antineoplastics, fluorouracil (5-FU) has been the mainstay of treatment of gastrointestinal, breast, and head and neck cancers for the past 40 years. Numerous active 5-FU schedules are in

The US Food and Drug Administration (FDA) has approved irinotecan (Camptosar) as first-line therapy for patients with metastatic colorectal cancer in conjunction with fluorouracil (5-FU) and leucovorin. The approval follows unanimous

New data from three additional trial studies confirm that long-term use of exisulind (Aptosyn) prevents the formation of precancerous colorectal adenomatous polyps in patients with familial adenomatous polyposis (FAP). These clinically significant

NEW YORK-Patients with advanced colorectal cancer have a median survival of only 12 months with single-agent chemotherapy. New drugs and new drug combinations are being tested in an attempt to find more effective treatments for the disease. A panel of researchers discussed trials of raltitrexed (Tomudex) in combination with other drugs at the Chemotherapy Foundation Symposium XVII.

The Food and Drug Administration (FDA) recently approved celecoxib (Celebrex) as an oral adjunct to the standard care (eg, endoscopic surveillance and surgery) of patients with familial adenomatous polyposis (FAP). Celecoxib, the only

Preliminary clinical data presented at a poster session of the 1999 annual meeting of the American Society of Clinical Oncology (ASCO) revealed that a significant number of patients with advanced colorectal cancer respond to first-line treatment with raltitrexed (Tomudex) in combination with oxaliplatin. The response rate of 59% suggests that this regimen may be one of the more active combinations under current investigation for the disease.

NEW YORK-A new oral combination chemotherapy regimen is as effective as intravenous fluorouracil (5-FU) and leucovorin, the current treatment standard, but with a superior safety profile. Speaking at the Chemotherapy Foundation Symposium XVII, Paulo Hoff, MD, assistant professor of medicine, M.D. Anderson Cancer Center, described the use of an oral regimen combining uracil/tegafur (UFT) and leucovorin as first-line treatment of metastatic colorectal cancer.

NEW YORK-The folate antagonist trimetrexate (TMTX) may be useful as a biochemical modulator of fluorouracil (5-FU) in the treatment of advanced colorectal cancer, according to preliminary results of a phase III trial conducted by the European TMTX Study Group and discussed at the Chemotherapy Foundation Symposium XVII

BUFFALO, NY-Colorectal cancer is caused by a multistep process, taking up to 25 years for an adenocarcinoma to develop. This offers multiple opportunities for prevention strategies to intervene and decrease the incidence of this disease.

BETHESDA, Md-G.D. Searle & Co. has won FDA approval for its COX-2 inhibitor Celebrex (celecoxib) as an oral adjunct to usual care (endoscopic surveillance and surgery) to reduce the number of adenomatous colorectal polyps in patients with familial adenomatous polyposis (FAP). The FDA initially approved Celebrex for treating osteoarthritis and rheumatoid arthritis in April 1998.

Laparoscopic operating techniques are gaining wider acceptance among colorectal surgeons, as their efficacy is proven. These techniques offer patients the advantages of fewer complications, decreased need for postoperative narcotics, faster

Chemoradiation is effective in controlling anal and rectal cancers but causes significant side effects and complications, according to three independent teams of colorectal surgeons in Australia and the United States.
