Computed tomography (CT) certainly is the key imaging modality used for the evaluation of mesothelioma. This applies to both the clinical assessment of mesothelioma and the staging of mesothelioma for therapeutic or epidemiological purposes. The morphological descriptors and criteria for the tumor node metastasis staging of mesothelioma are summarized in Tables 9.1-9.3.

Many tumors are staged according to the tumor, nodes, metastases (TNM) system. Metastases are cancer cells that have spread to sites distant from the primary tumor site and have started to grow. The most frequently occurring sites of metastasis of solid tumors are the brain, bone, liver, and lungs. 

Stage IV = Growth involving one or both ovaries with distant metastasis beyond the pelvis (i.e. if pleural effusion present, confirm cytology or any parenchymal liver metastasis equals stage IV). 

Discuss the role of temozolomide in the treatment of stage IV melanoma with or without central nervous system (CNS) metastasis. 

Stage IIB, IIC, and III melanoma are considered to be high risk because of their potential for recurrence and distant metastasis. The primary treatment modality is surgical excision of the tumor and a lymphadenectomy for patients with positive lymph nodes. 

In patients with SCC, metastatic spread to the lymph nodes occurs in less than 5%.32 The lymph nodes of the head and neck are the most common sites of metastasis. Patients are still curable with this stage of the disease, but they are at high risk of experiencing regional relapse and distant metastasis to the bones and lungs. As may be expected, survival is decreased compared with patients who do not present with nodal involvement. Factors that may be useful in... 

Not all tumors are seriously harmful. The body is able to wall off some tumors so that they do not spread such noninvasive tumors are said to be benign. Other tumors, called malignant, invade the body and destroy normal body tissues and organs. In advanced stages of cancer, malignant tumors may develop the ability to spread to other parts of the body and initiate new tumors, a process called metastasis. 

The aim of this chapter is to focus on two key attributes of malignant cells the ability to move and to spread across tissue boundaries as essential components of invasion and metastasis. It includes a summary of the most accessible, simple, reductionist (2-D) assays which are appropriate for the higher throughput early stage smdies, but also makes the case for the inclusion of more complex (3-D) assays and a description of those that can best be adapted for target validation and drug evaluation.

Because of early dissemination, staging of patients with small-cell lung cancer is more extensive than for patients with NSCLC. It is important to rule out distant metastasis because it will change the role of thoracic radiation in the treatment of these patients. Staging should include a complete history and physical examination, CAT scans of chest and upper abdomen to include the liver and adrenal glands, brain MRI scan, bone scan, complete blood count, and a possible bone marrow aspiration and biopsy. 

Patients with metastatic breast cancer are incurable using conventional therapy such as hormonal manipulation or chemotherapy. However, as in most other neoplastic diseases the bulk of knowledge on drug treatment has been obtained in this stage of the disease. The median survival from the manifestation of metastasis is approximately 18-24 months. It is, however, important to realize that metastatic breast cancer is a heterogeneous disease and for some patients the disease can be controlled for many years with relatively good quality of life.
