However, colorectal cancer and rates of fracture were reduced with combined hormonal treatment. 

In summary, combined estrogen plus progestin should not be used for the prevention of chronic diseases because it increases the risk of CHD, stroke, breast cancer, and venous thromboembolism. However, colorectal cancer and rates of fracture were reduced with combined hormonal treatment.

Capecitabine was clinically first approved for the co-treatment of refractory metastatic breast cancer. Its therapeutic spectrum has been expanded to include metastatic colorectal cancer, and there are hopes that it might broaden further as positive results of new clinical trials become available. Capecitabine, thus, affords an impressive gain in therapeutic benefit compared to 5-FU due to improved oral bioavailability and relatively selective activation in and delivery to tumors. 

Yet another SET domain protein, which is directly related to cancers, is SMYD3 that gets upregulated in colorectal cancer and hepatocellular carcinoma, a leading cause of death in developed countries (Hamamoto et al, 2004). 

It has been postulated that wood dust carcinoma results from a multistep process Exposure causes loss of cilia and hyperplasia of the goblet cells and initiation of cuboidal cell metaplasia, followed (after a quiescent period) by squamous cell metaplasia. Decades later, cellular aplasia leads to nasal adenocarcinoma. The time between first occupational exposure to wood dust and the development of nasal cavity adenocarcinoma averages 40 years. Other cancers, including lung cancer, Hodgkin disease, multiple myeloma, stomach cancer, and colorectal cancer and lymphosarcoma, have been mentioned in relation to wood... 

Cetuximab is a chimeric monoclonal antibody, against epidermal growth factor receptor (EGFR). It is given by intravenous injection with weekly intervals for the treatment of metastatic colorectal cancer and head and neck cancer. It is given in combination with the chemotherapeutic agent irinotecan. The... 

Adjuvant chemotherapy involves the use of antineoplastic drugs when surgery or radiation therapy has eradicated the primary tumor but historical experience with similar patients indicates a high risk of relapse due to micrometastases. Adjuvant chemotherapy should employ drugs that are known to be effective in the treatment of advanced stages of the particular tumor being treated. Adjuvant chemotherapy has played a major role in the cure of several types of childhood cancers as well as breast cancer, colorectal cancer, and osteosarcoma in adults.

Irinotecan is an analogue of camptothecin, a topoisomerase I inhibitor that is used for the treatment of advanced colorectal cancer and a few other solid tumors. Irinotecan is first converted to an active metabolite, SN-38, which is further conjugated into the inactive SN-38 glucuronide (SN-38 G), mainly by UGTIAI, and then eliminated via the bile. A common dinucleotide (TA) repeat polymorphism (containing 5, 6, 7, or 8 copies of TA repeat) has been identified in the UGTIAI promoter TATA box. 

Cetuximab is indicated for the treatment of head, neck and colorectal cancers, and in combination with radiation therapy it is used for the treatment of squamous cell carcinoma (locally or regionally advanced) of the head and neck. However, in patients with recurrent or metastatic squamous cell carcinoma of the head and neck whose response to the previous platinum-based therapy has not been positive, it is not given in combination with radiation therapy and is administered alone. Generally, a dose of 400 mg/m2 is initially administered in combination with radiation therapy followed by a maintenance dose of 250 mg/m2 and is administered 1 h... 

What the above amounts to is that the absolute excess risks per 10 000 woman-years attributable to the use of an estrogen plus a progestogen were seven more coronary heart disease events, eight more strokes, eight more pulmonary embolisms, and eight more invasive breast cancers, while the risk reductions per 10 000 woman-years were six fewer colorectal cancers and five fewer hip fractures. The absolute excess risk of events included in the global index was 19 per 10 000 woman-years. The overall harms in this study thus clearly exceeded the benefits. Allcause mortality was not affected. 

In 1848 patients treated with growth hormone during childhood there was an 11-fold increase in the incidence of colorectal cancer after a mean 16 years of follow-up and a 15-fold increase in mortality from colorectal cancer and Hodgkin s disease after 21 years of follow-up. However, there were too few deaths to draw any firm conclusions.

Levamisole was first synthesized for the treatment of parasitic infections. Later studies suggested that it increases the magnitude of delayed hypersensitivity or T cell-mediated immunity in humans. In immunodeficiency associated with Hodgkin s disease, levamisole has been noted to increase the number of T cells in vitro and to enhance skin test reactivity. Levamisole has also been widely tested in rheumatoid arthritis and found to have some efficacy. However, it has induced severe agranulocytosis (mainly in HLA-B27-positive patients), which required discontinuation of its use. The drug may also potentiate the action of fluorouracil (5-FU) in adjuvant therapy of colorectal cancer, and this combination has been approved for clinical use in the treatment of Dukes class C colorectal cancer after surgery. Its use in these cases reduces recurrences, and the mechanism... 

In addition to these breast cancer trials, trastuzumab is under evaluation for the treatment of other cancers in which HER2 overexpression can occur, including ovarian cancer, non-small cell lung cancer, colorectal cancer, and prostate cancer.
