Malignant disease metastatic

This novel -emitting potential anti-tumor drug49fM97 359 for metastatic malignant diseases has been obtained495,496 from the 6-chloromercury derivative (equation 227), involving reduction, phosphorylation and hydrolysis. 

Bisphosphonates (see later). Pamidronate is infused according to the schedule in Table 38.1 it is active in a wide variety of hypercalcaemic disorders. Fall in serum calcium begins in 1-2 d, reaches a nadir in 5-6 d and lasts 20-30 d. Etidronate may be given i.v. in hypercalcaemia of malignant disease. It acts in 1-2 d and a dose lasts 3 weeks it may also provide benefit for neoplastic metastatic disease in bone. Clodronate (oral or i.v.) or zoledonic acid (i.v) are alternatives. 

In 1968, Fishman and his collaborators reported the identification of an ALP in the serum of a patient with metastatic squamous cell carcinoma of the lung that was biochemicaEy and immunologicaUy identical with the ALP of a normal placenta. The newly discovered isoenzyme was termed the Regan isoenzyme after the patient in whom it was discovered. The Regan isoenzyme has been detected in tumor tissues and in sera of patients with many types of malignant disease and in some patients with nonmalignant diseases. An incidence of the isoenzyme of 3% to 15% in sera of cancer patients has been estimated, but this varies with the sensitivity of the methods used for its detection. Other variant forms of ALP have since been discovered in tumor tissues. These variants show many similarities to normal placental ALP but may differ in other properties, such as response to certain inhibitors.

Acute obstruction of the colon and rectum is caused by a number of benign and malignant diseases but by far the most frequent aetiology is colorectal carcinoma (Parker et al. 1997 Deans et al. 1994). Other maUg-nant causes include infiltration from adjacent mahg-nant tumour and metastatic involvement. Benign conditions such as diverticuhtis or other inflammatory bowel diseases (Crohn s disease, tuberculosis) and anastomotic or post-irradiation strictures are less frequent (Cascales-Sanchez et al. 1997 Rodier et al. 1987 De Lange and Shaffer 1991). 

Chemoembolization can be used in patients with ether primary or metastatic malignant hepatic tumors who are not surgical candidates (Table 2.5.1). Surgery is not feasible in advanced malignant disease involving both lobes of the liver, or complicating factors such as cirrhosis or failure of systemic chemotherapy. Likewise, TACE should be reserved for those patients who have liver-dominant disease, because the predominant effect is local. 

In contrast, secondary osseous malignancies may occur in about 30%-70% of all malignant diseases. For example, in breast and prostate cancer bone metastases can be found in about 70% and 60%, respectively. Metastatic disease to the bones is strong-...

For the successful treatment of human malignancy accurate staging and detection of primary and metastatic diseases is crucial. Liposomes have been shown to be useful for oncological radionuclide imaging. Profitt et al. (1983) demonstrated that stable, small.

Bladder cancer is the fifth most common malignancy in men. Approximately 70% of cases present with superficial disease and 30% have muscle-invasive tumors or metastatic disease. Radical surgery remains the standard treatment for invasive disease. Following cystectomy for muscle invasive bladder cancer, up to 50% of the patients will develop distant metas-tases (see Sternberg, 1995). 

Radiation therapy is a very important and effective treatment modality for almost all types of malignancies. Its importance in the local control of primary or bulky cancers will even increase in the future if more effective chemotherapeutic or other systemic treatments become available to treat metastatic disease. 

Ewing s sarcoma is the second most common malignant bone tumor in children. The majority of patients have microscopic metastases at diagnosis the lung is the most common metastatic site. This sarcoma is a relatively rare disease with limited therapeutic options. The majority of patients are initially responsive to chemotherapy with vincristine, doxorubicin (Adriamycin), and cyclophosphamide. However, relapsed disease is usually extremely difficult to treat because of its resistance to chemotherapy (Zhou et al., 2001).
