Tube thoracostomy, which uses a tube inserted into the chest for 24 hours to drain the fluid. This is usually followed by a process called pleurodesis. This process uses substances, such as talc, to stick the edge of the lung to the chest wall. This decreases the chance that the fluid will return. Temporary insertion of a catheter into the pleural space. You or your family member use the catheter to drain the fluid into a bottle as instructed by your doctor. Treating the cancer with chemotherapy to prevent the effusion from returning.
Dyspnea is a major respiratory symptom in such patients and is usually progressive. A cough is another nonspecific symptom. History is also useful in getting information about asbestos exposure to suggest mesothelioma and other conditions like drug-induced pleural effusion. Constitutional symptoms such as fever, decreased appetite, weight loss, night sweats, restriction of daily activities, although nonspecific one, are most often seen.
A previous history of malignancy at other body sites even in the remote past should be seriously asked in such patients. Physical examination should be thorough in these patients.
The findings of superior vena cava obstruction, soft tissue swellings or lymph nodes are important to suspect malignancy and reach the final diagnosis. In all women, a careful breast and pelvic examination should always be attempted as these may be the sites for primary malignancy. Respiratory system examination findings usually suggest pleural effusion in such cases depending on the amount of pleural effusion. One should not forget to leave the possibility bilateral pleural effusions that can occur in this situation.
It is almost always abnormal in patients with MPE. A standard chest radiograph can detect as little as 50 ml of pleural fluid on lateral view. A massive or recurrent effusion with shift of mediastinum to contra lateral side usually point toward underlying malignant etiology [ Figure 1a ].
Chest radiograph may also show some additional features such as lobulated pleural thickening, plaques, atelectasis, consolidation, mass lesion, mediastinal widening, reticulonodular shadows or lymphangitic patterns, etc. Even small or loculated effusion can be best detected on ultrasonography. Effusions with loculations and fibrous septa may sometimes give pseudo mass like appearance on chest radiography that may be resolved by chest ultrasound.
Chest ultrasound also detects tumor in relation to parietal pleura and chest wall. It is an important tool not only for screening but also in diagnosing MPE by doing guided aspiration, fine needle aspiration cytology, biopsy etc. It is superior to conventional chest radiograph and ultrasound in detecting pleural thickening and focal masses.
Not only pleural space but also the lung parenchyma and mediastinum can be assessed in such cases. The CT features highly suggestive of malignancy are nodular pleural thickening, pleural irregularity, mediastinal pleural thickening, circumferential pleural thickening, and pleural thickness more than 10 mm[ 10 ] [ Figure 1b ].
Magnetic resonance imaging MRI has a limited role in pleural effusion due to poor spatial resolution and motion artifacts. However T1-weighted images after intravenous gadolinium contrast may occasionally help in detecting pleural enhancement. MRI with triple-echo sequence has high sensitivity for small effusions and can identify features of fluid to differentiate exudates from transudative effusions.
However, false positive results can occur in uremic effusions, parapneumonic effusions, and following pleurodesis. The diagnosis of MPE requires demonstration of malignant cells in pleural fluid for that cytological examination of pleural fluid is required. Thoracocentesis is a must investigation in all exudative pleural effusion cases with strong suspicion of malignancy.
Pleural effusion with hemorrhagic or serohemorrhagic appearance is likely to be malignant. Pleural effusion in malignancy is exudate on biochemical analysis by light's criteria. However in rare instances, a transudative pleural effusion may also show malignant cells on cytological examination. A low sugar and low pH malignant effusion have diagnostic, therapeutic, and prognostic implications. The diagnostic yield of pleural fluid cytology is usually high in such cases, and the outcome of therapeutic interventions and survival is also poor in such patients due to extensive pleural involvement.
Pleural fluid cytology is a simplest and definitive method to diagnose MPE. When adenocarcinoma is diagnosed on cytology, it is difficult to identify the primary site of the tumor.
Three factors are important while considering the primary site of metastatic malignancies that include-The type of cells present in the effusion; location of effusion in relation to age and sex; and presence and nature of tumor at the distant site. Several tumor markers such as carcinoembryonic antigen CEA , carbohydrate antigen CA , CA, cytokeratin fragment, stage-specific embryonic antigen-1, nonspecific enolase etc. In patients of effusions of undetermined cause and negative cytology, an increased pleural fluid mesothelin or fibulin-3 level strongly favors mesothelioma.
Use of monoclonal antibody may help to differentiate malignant from benign effusion. Immunocytochemistry also helps in differentiating epithelioid mesothelioma from adenocarcinoma and also to establish the primary site of MPE in patients with an occult primary or multiple primaries. This is an essential investigation for the diagnosis of mesothelioma now days.
TTF-1 has high specificity for lung cancer [ Figure 2 ]. Different molecular tests such as fluorescent in situ hybridization and gene expression may complement cytology in diagnosing MPE but requires specialized equipment and personnel, therefore limiting its routine use in clinical practice.
Another method to diagnose MPE is to demonstrate malignant cells in the pleural tissue that can be done by pleural biopsy. A combination of pleural fluid cytology and needle biopsy of the pleura seems to improve the diagnostic yield compared to single technique alone.
Low diagnostic yield of pleural biopsy may be due to factors such as early stage disease with small pleural extension, location of tumor in those areas of pleura which are not approachable by needle including diaphragmatic, visceral, and mediastinal pleura , number of blind biopsy specimens at least 5 biopsy specimens are needed for accurate diagnosis , site of pleural biopsy higher diagnostic yield when lowest costal pleura is selected and inexperience of performing physician.
Image-guided pleural biopsy under ultrasound or CT guidance also improves diagnostic yield in cytologically negative pleural effusions compared to blind biopsy by Abram's or Cope's needle[ 25 ] [ Figure 1c ]. Thoracoscopy is considered to be gold standard in the diagnosis of MPE when previous investigation workup has turned negative.
Procedure can be performed under local anesthesia by semi rigid or rigid thoracoscope and under general anesthesia for video-assisted thoracic surgery VATS with single lung ventilation to sample the pleural lesions under direct vision.
Endoscopic features highly suggestive of malignancies are multiple nodule, polypoidal masses, pleural ulcerations, candle wax droplet lesions etc. Use of autoflorescence during thoracoscopy may be useful when early pleural malignancy are studied and has potential in diagnostic and staging of malignant mesothelioma.
Thoracoscopy has an important role in diagnosis and staging of lung cancer causing MPE. It is rare to find resectable lung cancer in presence of exudative pleural effusion despite having negative cytology. Therefore, thoracoscopy can establish operative eligibility by determining if the pleural effusion is paramalignant or due to metastasis.
Thoracoscopic appearance in a metastatic lung cancer as multiple nodules over both visceral and parietal pleural surface; b malignant mesothelioma as diffuse goose like pleural thickening with irregular pleural surfaces; c metastatic ovarian cancer as multiple small discrete nodules; d metastatic sarcoma as multiple large polypoidal nodules.
Thoracoscopy is also favored over thoracotomy in patients of malignant mesothelioma. As the pleural specimens are equally comparable, staging can be performed in a minimally invasive manner and fluorescence detection using 5-aminolevulinic acid can be applied to improve staging. These drugs widen the tubes called bronchi and bronchioles , or airways, in the lungs. This allows more airflow into the lungs.
Oxygen therapy is a treatment that gives you extra oxygen. It makes sure you get enough oxygen if you have trouble breathing. You breathe the oxygen in through a mask over your mouth or through tubes in your nostrils.

The tube has a light and camera at the end, so the doctors can see into your chest. For this procedure, you lie on your side.
You are given an injection of a sedative to make you feel drowsy. You also have a local anaesthetic to numb the area.
The doctor makes 1 or 2 small cuts to put the thorascope in. The procedure takes about 40 to 60 minutes. After the thoracoscopy, the doctors put a plastic tube chest drain through the cut. They use this to drain any remaining fluid. The drain is attached to a bottle or bag and secured in place with a stitch. You will usually be able to go home 2 to 5 days after a thoracoscopy. Some people may be able to have it and go home on the same day.

Causes of a pleural effusion A pleural effusion is common and is often caused by: lung infections, such as pneumonia heart failure, which is when the heart is not pumping blood around the body as well as it should.
The types of cancer that are more likely to cause a pleural effusion are: lung cancer breast cancer ovarian cancer l ymphoma s mesothelioma cancer of the pleura. Signs and symptoms of a pleural effusion Common symptoms of a pleural effusion include: breathlessness a cough chest pain.
If you are worried about any symptoms, speak to your healthcare team. Diagnosing a pleural effusion You may have a chest x-ray or an ultrasound scan , or both. Treating a pleural effusion The first treatment of a pleural effusion involves draining it to help with the symptoms. Draining a small pleural effusion If there is only a small amount of pleural fluid in the chest, the doctor may insert a small needle or thin tube cannula into the chest.
