Filter by:The primary purpose of this study is to determinate the degree of chest pain on patients with malignant pleural effusion submitted to pleurodesis with silver nitrate in three different dosages and concentrations ( 30ml 0.5% ; 30ml 0.3% ; 60ml 0.3%). Our secondary purpose is to evaluate the efficacy and occurence of adverse effects in the usage of silver nitrate for pleurodesis in the aforementioned dosages/concentrations.
1. Detection EGFR mutation of cancer cells from malignant pleural effusion. 2. Established the cancer cell lines with without EGFR mutation from malignant pleural effusion.
RATIONALE: Morphine and ibuprofen help lessen pain caused by pleurodesis. It is not yet known whether one drug is more effective than the other in lessening pleurodesis-related pain or whether the size of the chest drain tube affects pain. PURPOSE: This randomized clinical trial is studying ibuprofen to see how well it works compared with morphine in treating pain in patients undergoing pleurodesis for malignant pleural effusion.
Pleurodesis is a technique used to fuse the two layers of the lining over the lung. This is done to get rid of collections of fluid or air in this space. A common reason would be cancer of the underlying lung or elsewhere causing fluid to collect in the pleural space. In this situation it is a palliative procedure to free the patient from symptoms like breathlessness.
Connective tissue growth factor (CTGF) is known to be a fibrogenic cytokine, it could be expressed in various fibrosis diseases. But, recent research showed that CTGF also be considered to be a tumor suppressive gene. The expression of CTGF protein is higher in normal Type I and II alveolar epithelial cells than metastatic tumor cells. CTGF appears to be a suppressor of lung tumor invasion and in metastasis and the decreased CTGF expression in tumor tissues was associated with advanced tumor stage, lymph node metastasis, early postoperative relapse and shorter patient survival. CTGF can be expressed in many human organs such as heart, brain, placenta, liver, muscle, kidney, peritoneal mesothelial cells and lung but did not known in the pleura. The CTGF protein is present in the peritoneal cavity and is increased during peritonitis. Considering pleural cavity comes from the same origin of mesenchyma with peritoneum, pericardium and fallopian tube, we aim to evaluate whether the CTGF expression increase in the pleurisy patients including the parapneumonic effusion and the TB pleurisy. The diagnosis of TB pleurisy depends on the effusion TB culture and pleural biopsy. Unfortunately the sensitivity of TB culture was only 20-30%. So most patients must receive invasive pleural biopsy. Adenosine deaminase(ADA) was developed as a screening test but should not be considered an alternative test to culture and biopsy. The sensitivity of ADA might vary from 32%-100% and the cutoff value also vary from 26 to 70 IU/L. We should develop a method to alternate the culture and biopsy . Therefore, our technologist Jao-Jia chu will develop the CTGF ELISA kit for this specific aim. If CGTF might increase expression in pleuritis but decrease in pleural metastasis, it might be a potential method help to differentiate lymphocytic pleural effusion between TB pleurisy and malignancy.
