Active clinical trials for "Pleural Neoplasms"

This phase II trial evaluates how well transarterial chemoembolization (TACE) works for treating patients with non-small cell lung cancer. TACE is a minimally invasive procedure that involves injecting chemotherapy directly into an artery that supplies blood to tumors, and then blocking off the blood supply to the tumors. Mitomycin (chemotherapy), Lipiodol (drug carrier), and Embospheres (small plastic beads that block off the artery) are injected into the tumor-feeding artery. This traps the chemotherapy inside the tumor and also cuts off the tumor's blood supply. As a result, the tumor is exposed to a high dose of chemotherapy, and is also deprived of nutrients and oxygen. TACE can be effective at controlling or stopping the growth of lung tumors.

This phase II trial investigates the effect of EXPAREL compared to lidocane as a local anesthetic in patients who are undergoing pleuroscopy with pleural biopsy and indwelling pleural catheter placement. This trial aims to see whether EXPAREL or lidocane is able to make patients more comfortable.

pleura is a serous membrane, it consist of parietal pleura and visceral pleura. pleural thickening is any form of thickening involving the pleura more than 3 mm. there is malignant thickening : methoselioma, metastasis and non malignant thickening. trans thoracic USn is a reliable , safe and gold standard for studying pleura.

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

The PROSPECT study aims to look at the number of problems or side effects which occur after patients have had a procedure completed to remove fluid or air from the space between the lung and the chest wall. Other information will also be collected to see whether anything else affects which patients have problems after the procedure such as bleeding or infection. This study will also investigate whether it is possible to find out which patients are likely to feel a lot better after the procedure. Not all patients feel significantly better but it is not clear why this is. There are a number of different reasons patients may not feel better, for example if the lung is not able to fully re-expand. The study aims to look at whether it is possible to predict these problems before the procedure using ultrasound. If it is possible to find the answers to some of these questions it might be possible to prevent patients undergoing treatments which are not likely to benefit them. The study will use information already collected as part of clinical care, as well as questionnaires from patients receiving care at a variety of centres. The different features of these centres will also be considered in analysis.

Recently, probe based confocal laser endomicroscopy showed to be able to distinguish malignant from benign pleura during medical thoracoscopy. However The clinical usefulness of this new tool remains to be determined. The investigators believe that pCLE could be part of mini invasive pleural disease management and could be used during thoracentesis in order to increase the diagnostic yield of this procedure. The investigators are starting a prospective trial to recruit patients referred for medical thoracoscopy to the endoscopy unit. First, the pCLE probe will be introduced through the Boutin's needle or the thoracentesis catheter, just before the thoracoscopy, in order to investigate the pleural pCLE features and to identify or exclude malignant infiltration. Second those features will be compared to the pCLE acquisition obtained during the medical thoracoscopy (the probe is introduced through the working chanel of the thoracoscope), under visual control. In order to compare the invasive and mini invasive acquisition, 10 criteria will be prospectively assessed.Third, These features will be compared to the histological samples performed during thoracoscopy. Finally, the interpretation of different investigators will be compared. The 10 criteria are presented below: Abnormal tissular architecture No: Correct identification of the previously described normal pleura characteristics Yes: identification of cellular/tissular structures which are not known to correspond to normal pleura (cellular clusters or dark clumps, glands, cells cordons, dysmorphic cells, papillar distribution….) Cellular homogeneity is size, shape and fluorescence, as subjectively assessed by the investigator yes no Mean cellular size: Small: < 10µm Moderate: 10 - 20µm Large: > 20µm Cellular density (with reference to the Chia seed sign) Low (lower than the Chia seed sign) Moderate High Dysplastic vessels: Yes: (vascular leaks, tortuous or giant vessels) No: no dysplasia Vascular density (on a full optical area) Low: 0 -2 vessels Moderate: 3 - 4 vessels High: > 4 vessels Organized or anarchic connective fibers Anarchic: coarse fibers, irregular in shape, without well-defined architecture Organized : regular in shape and direction, well defined architecture. Chia seed sign on a full optical areal yes No

The purpose of this study is to determine the response rate and overall survival in patients that have been diagnosed with mesothelioma and will undergo chemotherapy, surgery and intensity modified radiation therapy (IMRT) as part of their standard of care.

This study is designed to obtain preliminary data comparing indwelling pleural catheters (IPCs) versus IPCs plus doxycycline for pleurodesis as treatments for malignant pleural effusion (MPE). Indwelling pleural catheters (IPCs) are commonly used to treat pleural effusions (build-up of fluid in the lungs). Doxycycline is an antibiotic that is also used to treat pleural effusions. The goal of this clinical research study is to learn if adding doxycycline to the use of an IPC can lead to shorter treatment times with IPCs.

The purpose of this study is to evaluate the accuracy of participants imaging versus staging procedures. The investigators will consent subjects that are scheduled to undergo staging procedures to diagnose malignant pleural mesothelioma (including pleuroscopy, bronchoscopy, endobronchial ultrasound and laparoscopy) as part of their standard of care.

The purpose of this study is to determine whether radiation therapy decreases tumor size and tumor spread. The investigators will consent subjects that have been diagnosed with mesothelioma and will undergo radiation therapy followed by surgical resection as their standard of care. The investigators will collect data from past and future medical records as well as data regarding their health status for their lifetime by reviewing life status, treatment status and CT scans.
