Treatment of mesothelioma is tailored uniquely for each patient. Often the scene of the malignant mesothelioma at diagnosis dictates treatment options. Directed by a particular disease help also to the medical team in planning not only treatment but also in estimating prognosis as well as in the identification of existing clinical trials that the patient may be eligible. Three staging systems are currently used for pleural mesothelioma. None is used for Peritoneal Mesothelioma.
Knowledge of how to develop a particular cancer is relevant for the staging process. Some staging systems cover only specific cancer while others can be used to cover a variety of types. Some common elements are found in most development scene of systems, namely, location of the primary tumor, the tumor size the number of tumor, lymph node, type of histology, grade of the tumor and the presence of metastases.
To accurately determine the stage of cancer, doctors are usually based on a variety of techniques. It is physical examinations, including roentgenograms, CT scans, MRI, imaging techniques and analysis of PET. Review of blood, urine, serum and tissues of the patient biopsy can also provide useful clues. Tumor markers can also be used. Pathology reports are very useful to provide information on the exact size of the tumor, extension of the tumor in the neighbouring structures and histology of the tumor and the category. Surgical reports also provide assistance to the staging.
The most frequent, cancer staging system is used for mesothelioma is the TNM (primary tumor, regional lymph nodes, distant metastases). Stage I is affected when mesothelioma involves only pleura, ipsilateral lung, pericardium ipsilateral and ipsilateral diaphragm. Lymph nodes are not affected. Phase II is assigned when Mesothelioma has already involved the Hilaire ganglia near the side contralateral. The lung, pericardium, or diaphragm on the side contralateral may also be involved. Stage III is assigned when the Mesothelioma has spread to involve the chest wall, soft tissue, ribs, heart, esophagus, or other organs in the chest cavity in the side ipsilateral. Lymph nodes may or may spread to the lymph nodes on the same side as the primary tumor. Stage IV is assigned to the disease has either already spread to the lymph nodes in the chest on the side contralateral to the primary tumor, extended to the contralateral pleura, or extended to the organs in the abdominal cavity or neck. Presence of distant metastases is considered stage IV.
Butchart is the oldest system of gathering for cancers. It is also the most commonly used system of gathering for all types of cancer. The extent of the primary tumor, the mass is the basis of this system. Stage I is affected when mesothelioma is located in any pleura, or on the ipsilateral diaphragm. Phase II is assigned when the Mesothelioma has spread to the chest wall, oesophagus, heart, or pleura on both sides. The lymph nodes in the chest may also be affected. Stage III is assigned when the Mesothelioma has invaded the diaphragm and reached the peritoneum. Lymph nodes outside of the chest may also be involved. Stage IV is assigned when there is evidence of distant metastases.
The Brigham system is the latest system to develop. Resectability and lymph nodes of participation is the basis of this system. Stage I is affected when mesothelioma is resectable always, with any of the lymph nodes. Phase II is assigned when mesothelioma is resectable but are involved in the lymph nodes. Stage III is allocated when mesothelioma is inoperable, extended to the neighbours of the structures of the chest and may or may not have extrathoracic lymph nodes. Stage IV is assigned when there are distant metastases.
Information gleaned from these systems of rest shall be disclosed to the patient. Patients reserve the right to know the exact state of their disease and all parties involved will benefit greatly when this disclosure is made.
