Metastatic cancers

Red blood cells also contain sufficient acid phenylphospha-tase for mild hemolysis to cause false elevations. Therefore, inhibitors such as ethanol, formaldehyde, copper sulfate> and 1-tartrate have been used to inhibit selectively the enzyme of one or more tissues and enhance the specificity of the test (101). Ethanol is unsuitable because it inhibits the enzyme from erythrocytes and prostate simultaneously, and because it yields serum activities which correlate poorly with prostatic disease. Formaldehyde inhibits the erythrocytic enzyme and has been said to yield clinically satisfactory results. The copoper resistant acid phosphatase of serum is elevated by metastatic carcinoma of the breast, as well as by other metastatic cancers, and is also elevated by a wide variety of non-cancerous diseases. 

Chemotherapy is the primary treatment modality for metastatic colorectal cancer (MCRC). Treatment options are generally similar for metastatic cancer of the colon and rectum.

Approval Letter The drug is approved. An example of the approval news for Tykerb, a kinase inhibitor in combination with capecitabine for the treatment of advanced or metastatic cancer, is presented in Exhibit 8.3. 

The phase-three results were unblinded in March 2003 and overall, for all types of metastatic brain cancer, were reported as nonpositive, showing the drug to have efficacy but not at the statistical level set at the beginning of the trial by Alios Therapeutics Inc. for a successful phase-three trial. The subset analysis for the different types of metastatic cancer to brain, however, showed that breast cancer patients had a 100% increase in survival. The 500 plus patient trial also demonstrated RSR 13 to be extremely safe, confirming our early design feature of using a known antilipidemic drug, clofibrate, as a substructure. An NDA for RSR 13 with trade name efaproxaril was reviewed by the PDA on a fast track review for use in treatment of metastases of breast cancer to brain. 

In an open-label dose-escalation phase I study, 26 patients with advanced or metastatic cancer received doses ranging between 180 and 1000 mg. Dose levels up to 800 mg were well tolerated with adverse events being hypertension, fatigue, and dizziness. The agent produced partial responses in two patients, while three patients were presented with stable disease of over 6 months. 

Metastatic cancer- May be used secondarily in women with advancing inoperable metastatic (skeletal) breast cancer who are 1 to 5 years postmenopausal. Primary goals of therapy include ablation of the ovaries. This treatment has been used in premenopausal women with breast cancer who have benefited from oophorectomy and have a hormone-responsive tumor.

Levamisole (Ergamisol) is an antiparasitic drug that has been found to enhance T-ceU function and cellular immunity. The drug improves survival of patients with resected colorectal cancers when combined with 5-fluo-rouracil the mechanism of this interaction is not known. Levamisole does not have antitumor activity against established or metastatic cancer and has not been found useful in the adjuvant therapy of cancers other than colorectal cancer.

Radiophosphorus is used in the treatment of patients with a number of diseases, lliis element has a half-life of about 14 days and emits beta rays. It is taken up by die body in the greatest quantity by those tissues which manufacture blood cells. In polycythemia vera, a condition in which too many red blood cells arc formed, the radiation from this isotope often brings about a sufficient suppression of the blood cell-making tissues to alleviate some of the symptoms of the disease. Leukemia patients, in whom there is an excessive production of white cells, are offered added comfort and, m some instances, prolongation of life by the use of radiophosphorus. This element also may be used m treatment of metastatic cancer to the bone and, although the treatment is not used in an attempt to eradicate cancer, it can result in significant palliation of pain in some patients. 

Megestrol acetate has also proved of value in patients with metastatic prostatic cancer, epithelial ovarian cancer, or malignant melanoma and is therefore used in both sexes. The adverse effects are very similar in men to those seen with oncological doses in women loss of libido and potency is likely to occur in male patients. In one clinical study of 43 men with recurrent and metastatic cancer of the prostate given megestrol acetate 160 mg/ day orally, five developed a symptomatic rise in liver...

However, several types of cancer do not respond well to treatment. For example, the majority of metastatic cancers cannot be cured by current chemotherapeutic methods or by any other type of treatment.11 In addition, some of the most common forms of adult neoplastic disease are difficult to treat by using anticancer drugs. As indicated in Table 36-9, the number of deaths associated with colorectal, prostate, and breast cancer is unacceptably high, and the mortality rate for lung cancer and pancreatic cancer is well over 90 percent in both men and women. 

However, it has been reported that the initial dose of 2.0 jig/kg/min led to excessive anticoagulation even in patients with normal hepatic function (40,41). In some patients in cardiothoracic intensive care units or with metastatic cancer, a dose reduction could be proposed. In the ongoing investigator s initiated trial for HIT in Japan, lower initial dose of 0.7 jg/kg/min is used (42). Empirically lower doses are used in Japan than in Europe or United States.

As Mrs KT has advanced metastatic cancer, the goal of treatment is palliative. The objectives must therefore be to prolong her life by controlling her tumour growth in both the primary site and sites of metastases, in parallel with maintaining or improving her quality of life. It is imperative not to impair her quality of life with intolerable side-effects of treatment. The role of the clinical oncology pharmacist is therefore important and should involve ... 

This may be due to liver capsular pain from liver metastases. Mrs CR s abnormal liver function tests may indicate this. If metastatic cancer has spread to her liver, the resultant disease within the liver capsule may cause pain. Another possible cause could be the high dosage of senna that she is taking (8 tablets a day) -excessive dosages of stimulant laxatives such as senna can cause abdominal cramp and pain due to their effect of increasing intestinal motility.
