Clinical diagnosis of pleural mesothelioma

Pleural mesothelioma is pleural primary tumor, there are localized (mostly benign) and diffuse (all malignant) points. Which diffuse malignant mesothelioma of the chest tumor one of the worst prognosis.
In most patients between the ages of 40-70, male than female.

The first symptom of chest pain, cough and shortness of breath as the most common. Have fever, sweating or joint pain mainly v. symptoms. About half of patients over a large number of pleural effusion with severe shortness of breath. No large pleural effusion are often more severe chest pain, weight loss common.
Ordinary X-ray found that pleural effusion, and lung tumor tissue was wrapped and so on, in advanced cases may have pericardial effusion caused by heart shadow expansion and soft tissue shadow and rib destruction. For patients with suspected malignant pleural mesothelioma, CT examination is most useful. Pleural effusion cytology are diagnostic.
Routine laboratory examination, some patients may have thrombocytosis, serum carcinoembryonic antigen (CEA) level rise. For routine examination can not clearly diagnosed, and can be used to do thoracoscopic pleural biopsy. In general the majority of patients who obtain a diagnosis.

Check that you have been infected with diffuse malignant mesothelioma

Laboratory examination:

Reduced hemoglobin, erythrocyte sedimentation rate accelerated, the majority of patients with platelet count increased, platelet-up to the individual reported that 1000 × 109 / L, indicates a poor prognosis of serum carcinoembryonic antigen in some patients with elevated serum alpha-fetoprotein normal. Serum IgG, IgA, or IgM increased, the reasons for not yet specified, but can also have elevated serum anti-diuretic hormone, hemolytic anemia, hypercoagulable state, hypercalcemia low blood sugar, etc.

Other auxiliary check:

1.X-ray chest image and the lateral anterior, as can clearly show ipsilateral pleural effusion, often accounting for 50% of cupping the side of the chest Network. About half of patients in addition to pleural effusion, the chest X-ray can also be seen on the pleura along the wavy wall showing the growth of multiple ù clumps shadow, as well as diffuse pleural nodular pleural thickening and pleural calcification may be associated with. These diffuse malignant pleural mesothelioma diagnosis provide valuable clues. Ipsilateral lung tumor tissue was wrapped ipsilateral mediastinal shift with tumor side of the chest cavity smaller condition late X-ray showed widened mediastinum, pericardial effusion to expand the heart shadow, showing soft tissue shadow and rib destruction of cupping network.

2. Chest CT can show the tumor size and scope. Know whether the tumor invaded beyond the borders of ipsilateral mediastinal structures ù chest, or under the invasion of the diaphragm and the diaphragm structure is very important. Typical performance is: can show ipsilateral thorax narrowed, pleural thickening and pleural effusion significant health search, a small number of cases of pleural plaques can be seen. In addition, chest CT also clearly shows along the pleural surface of large irregular-shaped lumps, some of the growth of tumors along the interlobar fissure and extends into the mediastinum, the diaphragm, there are also long into the contralateral posterior mediastinum through the chest can still be seen in some patients pulmonary surface nodules, nodules have irregular calcification. Last Health Search in the chest CT and tumor on the chest wall along the edge you can see a dense calcified plaque and line-like calcification in the chest CT and sometimes visible tumors grow bony thorax, ribs and chest wall soft tissue damage block shadow (Figure 3 Health Search 4).

What is the treatment of diffuse malignant mesothelioma

Treatment:

Although a number of ways the current treatment of diffuse mesothelioma, but there is no very effective treatment for different patients, different health search for medical conditions, selection of treatment methods are very different, but after a certain method of treatment, have a small number of patients live at home and abroad over five years, the longest up to 22 years, most people think may be related to the natural survival time and tumor staging of cupping network. By Butchart staging of malignant pleural mesothelioma is divided into four .

According to clinical manifestations of stage Ⅰ epithelial type malignant pleural mesothelioma, may be long-term survival, according to disease invasion range of options, or pleura pleural stripping surgery involving the organization, together with en bloc resection (resection of the lung pleura, pleura chest wall resection, etc.) on Ⅱ, Ⅲ and Ⅳ epithelial type, and other pathological types of cases, regardless of governance and died, with curative or palliative surgery and the use of chemotherapy and radiotherapy or not, the survival curves after treatment is basically the same, the average survival time of 18 months About 10% of patients survive the 3 years. The current trend in health search is to surgery, chemotherapy, radiotherapy and supportive care measures together, namely the freedom to line tumor reduction surgery in order to line radiation therapy or external radiation therapy between organizations. Supplemented by radiotherapy and then chemotherapy. In order to control the regeneration rate of pleural effusion and reduce chest pain.

1. Palliative treatment of malignant pleural mesothelioma, a patient search for pleural effusion, needle aspiration will occur soon after, using chemical agents into the pleural cavity, resulting in pleural adhesions, most patients have been brought under control of pleural effusions Health Search This pleurodesis If it fails or health search in the proposed line of diagnostic thoracotomy in patients with pleural endarterectomy should be considered done.

Malignant pleural mesothelioma can be along the puncture hole, set access and chest tube thoracotomy incision disseminated health search, but the network of the skin caused by fire can rarely cause symptoms of sediments, so do not have treatment, if given to the patient treatment, these skin junction section also observe the effect of ù can be used as indicators.

Chest pain patients with malignant pleural mesothelioma health of search is the most difficult to deal with symptoms, particularly severe in advanced, all day it continues, no response to radiotherapy should be given enough sedative analgesics, including opiate preparations to relieve pain, degree of life safety ù the last moment.

2. Surgical treatment of traditional surgical methods are: wall / visceral pleura resection and pleural pneumonectomy. Both methods are considered the treatment of tumors associated tumor reduction method. Any kind of surgical operation using the above method to complete tumor cytoreductive surgery makes ù adjuvant radiotherapy and chemotherapy to maximize the local effect.

Symptoms of diffuse malignant mesothelioma

Clinical manifestations:

Men, more common, male to female ratio of about 2:1,2 / 3 of patients aged 40 to 70 years old. About half of the patients described the history of asbestos exposure. Slow onset health search, variety of clinical manifestations. Epithelial-type and mixed type of pleural mesothelioma, often accompanied by a large number of pleural effusion ù, but usually only a small amount of fiber types with or without pleural effusion. Epithelium of patients seems to be more involving the subclavian or axillary lymph nodes and extend to the pericardium, contralateral pleura, and peritoneum; fiber multi-distant metastasis and bone metastasis.

Early stage of disease, the lack of specific symptoms, 60% ~ 90% of patients with chest pain, shortness of breath, dry cough and shortness of breath , approximately 10.2% of patients have fever and other uncomfortable symptoms, 3.2% of the patients with joint pain mainly v. symptoms of patients often cough, mostly dry cough, no sputum or sputum volume small, there is no sputum blood  Patients with malignant pleural mesothelioma, the symptoms of shortness of breath, obviously cupping network, especially since the activities of chest tightness, shortness of breath, increased significantly, with a break to alleviate symptoms of dyspnea secondary to pleural effusion, pleural effusion and tumor extent with the increase of aggravated . Early in the pleural cavity fluid is free, and then gradually restricted parcels, the last large piece of tumor tissue is gradually replaced as a vague dull chest pain initially, when the tumor invasion intercostal nerve pain limitations.

Symptoms of diffuse malignant mesothelioma

Symptoms of diffuse malignant mesothelioma

Complications:

Are currently no relevant information

Diagnosis:

According to the patients can have a history of asbestos exposure history. Physical examination found diminished breath sounds and percussion dullness prompt pleural effusion, or tumor growth in the advanced observation and palpation of chest wall, in particular the intercostal, we find that tumor swelling, suggesting that invasion of chest wall tumors. Combination of laboratory tests and chest CT examination can determine if the pleural calcification or bone structure, has damaged the health of search. Malignant pleural mesothelioma should be considered possible . But in order to diagnosis, need further examination and pleural effusion by pleural biopsy to be determined. Network currently in use cupping technique  video-assisted thoracoscopic biopsy diagnosis rate of up to 100% of surgical risk and mortality rates are low, an alternative to exploratory thoracotomy biopsy.

Differential Diagnosis:

Although the pleural effusion smears, breast and wearing a pleural biopsy and pleural effusion cell block sections can make the diagnosis of malignant cupping network, but can not identify metastatic adenocarcinoma and malignant pleural mesothelioma ù primarily by light microscopy electron microscopy, histochemistry, immunohistochemistry, hyaluronic acid measurement methods such as differentiated from metastatic adenocarcinoma with pleural.

Is relatively sure that the diagnosis of malignant mesothelioma, there are three kinds of technology, namely, periodic acid - Schiff staining liquid to do in order to keratinocytes and carcinoembryonic antigen for the immune peroxidase test and electron microscopy. To carry out these checks, biopsy specimens must be immediately fixed with neutral formalin solution, another small piece of tumor biopsy specimens destined for the glutaraldehyde solution for electron microscopy using the

1. Periodic acid - Schiff stain (PAS) is the only reliable histochemical method can distinguish between malignant pleural mesothelioma and adenocarcinoma metastatic adenocarcinoma, although the characteristics of a variety of different, but after amylase digestion strong positive vacuole, can be diagnosed with malignant pleural mesothelioma than adenocarcinoma.

Prognosis and prevention of pericardial mesothelioma

2, early detection of early diagnosis and early treatment of comprehensive measures to limit the disease, such as the preferred surgical resection lesions can be completely removed, however, were very few lesions were diffuse pericardial excision of pericardial decompression or openings, been able to alleviate clinical symptoms, but poor prognosis.

Pleural mesothelioma, often associated with exposure to asbestos, and therefore, pay attention to labor protection, reduce or avoid contact with asbestos is an effective measure to prevent this disease. Were mostly localized benign, surgical treatment well; even malignant diffuse-type who used to Adriamycin-based chemotherapy can also be achieved positive results, can significantly prolong survival.

Pericardial mesothelioma case analysis?

Discussion: heart, pericardium tumor is a rare disease, primary tumors found in autopsy or about 1 / 2000. The clinical manifestations of cardiac tumor was non-specific, susceptible to misdiagnosis. In this case, the early onset, only a bloody pericardial effusion in performance in the 1st line of the hospital thoracotomy stylish dissection of pericardial adhesions failed to find the cancer, according to TB patients to anti-tuberculosis + hormone therapy to alleviate a certain condition , it has been misdiagnosed, and more than one month after the hospital again, echocardiography tumor was found and the autopsy confirmed pericardial mesothelioma. Mesothelioma occurs more in the clinical pleura, pericardium and mediastinum can be involving, primary pericardial mesothelioma is especially rare. Pleural effusion pleural mesothelioma mostly bloody, high proportion of high protein content, glucose and pH, often reduce the high level of hyaluronic acid, and LDH. Such as pleural effusion of hyaluronidase significantly increased, suggesting that malignant mesothelioma. In this case the change is also consistent with pericardial effusion pleural mesothelioma pleural effusion, indicating a characteristics of pericardial effusion mesothelioma pleural mesothelioma with pleural effusion is characterized by consistent, which provides for the early diagnosis of disease based on more .

The cause of pericardial mesothelioma pathology

The treatment of malignant pleural mesothelioma is still no effective method to tackle. Treatment methods, there are palliative treatment, surgical treatment, chemotherapy and radiation therapy is generally believed that the relatively limited for cancer patients in Phase I, advocated doing radical resection of the lung pleura. For Ⅱ, Ⅲ, Ⅳ stage patients, radical surgery has no meaning, only the implementation of palliative surgery. In fact, the majority of patients to disease diagnosis, has been in Phase II or above. Rapid growth in patients with pleural effusion often leads to severe respiratory difficulties, so palliative surgery for improving the quality of life of these terminally ill patients is significant. Previously used intrapleural chemotherapy drugs such as fade or promote pleural adhesion pleural effusion latch means is often difficult to be effective.

With thoracoscopic pleurodesis in malignant pleural mesothelioma, palliative treatment achieved good results, assisted thoracic surgery can completely clean the pleural fluid aspiration, and the full separation of adhesions, so that lung recruitment, and then injected into sterile talc powder, for pleurodesis to control the production of pleural fluid to alleviate clinical symptoms in patients with advanced cancer.

he main causes of mesothelioma patients have of asbestos exposure. About 70 – 80% of the mesothelioma patients were diagnosed exposed to asbestos in their work history. However, there are a number of mesothelioma patients had no record of any contact with asbestos. Asbestos fibers may be dispersed in large numbers into the air and minerals. Asbestos was widely used in many industrial products, including cement, brake linings, roof  shingles, textiles and insulation materials. If tiny asbestos particles float in the air, especially in the manufacturing process, they will be inhaled and cause serious health problems. In addition to mesothelioma, the right to increase exposure to asbestos lung cancer, asbestosis (noncancerous, chronic lung disease) risk, and other cancers, such as throat and kidney cancers.

Mesothelioma frequent lung or abdominal membrane. Although the disease usually takes several decades of asbestos exposure in the formation of mesothelioma, but once there, it will very quickly spread and deteriorate.

Because the symptoms of mesothelioma and other diseases can resemble the lighter, coupled with the onset of the disease for a long time interval, mesothelioma patients with the disease usually have to wait until after the onset of the symptoms can be felt. .

The combination of smoking and asbestos greatly increases the risk of air-channel diseases.

Advance understanding of mesothelioma

Most of malignant mesothelioma was due to long-term work on asbestos environment, incoming live in the exposure to asbestos or asbestos caused the family environment. In rare cases, even the one-month exposure to asbestos can also lead to mesothelioma.
National Cancer Institute of mesothelioma is defined as: mesothelioma is a rare find in the mesothelial cells of the malignant cancer. Most of the patients suffering from mesothelioma due to asbestos floating work environment, and therefore caused by inhaling asbestos particles.

Mesothelioma frequent lung or abdominal membrane. Although the disease usually takes several decades of asbestos exposure in the formation of mesothelioma, but once there, it will very quickly spread and deteriorate.

Because the symptoms of mesothelioma and other diseases can resemble the lighter, coupled with the onset of the disease for a long time interval, mesothelioma patients with the disease usually have to wait until after the onset of the symptoms can be felt. .

What is mesothelioma?

Basically, four stages of the disease in advance mesothelioma. In the first phase, in the lung lining region that began the formation of tumors, and not from the side of the lung beyond. In the second stage of tumor in the chest and then extended to other organs, such as the heart. Then in the third stage of its right also affect all other organs, the extent of other gastrointestinal organs. And eventually enter the fourth and final stage of tumor extended to all parts of the body and adversely affect all components. These are some of mesothelioma symptoms, diseases can be tracked into the initial stages of its occurrence.
