Is recommended that the clinician include that information with the order so that everyone understands what the correct dosage is for that patient. Chemotherapy dosages should be checked for route and dose to determine that the dosages prescribed are correct according to the regimen and do not exceed dosing guidelines. Appropriate laboratory values should be checked to verify that dosages are correct for any organ dysfunction present, and drug interactions should be scrutinized closely (tables 88–7 and 88–8). Health professionals administering chemotherapy should check the dosage calculation for the patient’s weight or bsa along with the five rs of administering medication (ie, right patient, right medication, right dose, and right route, at the right time). If there is any question about the safe dosage or safe administration of a chemotherapy agent, the chemotherapy should not be administered until the question is resolved.

Based on clinical practice guidelines published by the american society of clinical oncology, it is recommended that clinicians routinely use an obese patient’s actual body weight, instead of an ideal body weight or other measurement. Oral chemotherapy over the past decade, self-administration of oral chemotherapy has increased because of the availability of oral, novel anticancer agents. Although oral chemotherapy has many advantages, such as convenience for the patient, potential increase in quality of life, and decreased treatment-associated costs, it also comes with an increased risk of medication errors, less monitoring of adverse effects and drug, dietary supplements, otc medication and/or food interactions and accidental exposure to other individuals. Health professionals have an important role in ensuring safe handling of oral anticancer agents, and should be properly trained and perform competently within guidelines for the storage, handling, and disposal of oral agents. The health professionals are also expected to provide proper training and education on safe handling and proper administration ( see table 88-9) for the patient and caregivers. 47 cancer survivorship as early detection of cancers and effective therapies have improved over the last several years, the number of cancer survivors has increased.

All adults are advised to have colorectal cancer screening per ormed between the ages o 50 and 75 with ecal occult blood testing, exible sigmoidoscopy, or colonoscopy (usps f 2008). Colonoscopy is considered the gold standard or screening. When compared directly, both ecal occult blood testing and exible sigmoidoscopy were demonstrated to reduce colorectal cancer mortality, but neither showed a greater mortality bene t rom the other.27 when should colon cancer be suspected in a patient?.

Iron de ciency results in a hypo-proli erative anemia, meaning that the reticulocyte count will not be increased. Iron studies demonstrate low serum iron, increased total iron binding capacity, and low erritin. Of 39 patients found to have brain metastases from colorectal cancer, 43% had cerebellar involvement, with isolated cerebellar lesions in 23%.
