Active clinical trials for "Lymphadenopathy"

This phase II study of high dose intensity modulated radiation therapy in the cervical cancer with metastatic lymphadenopathies at initial diagnosis

This study compares the yield of 19-gauge needles vs 21-gauge needles during EBUS TBNA procedures.

To perform image-guided laparoscopic intra-abdominal lymph node biopsy with goal of minimizing surgical risk and improving accuracy of biopsy.

The study was performed to determine if either ultrasound guided core biopsy or fine needle aspiration of an axillary lymph node has superior sensitivity in detecting metastatic carcinoma from the ipsilateral breast.

Impact of screening nodes mediastinal by PET, at different times of the management of cancer disease, remain unclear. Benefits of combined PET and puncture with echoendoscopy for the diagnosis subsequent therapeutic management should be evaluated in these different contexts. We would like to demonstrate the clinical utility of this association to replace more invasive diagnostic procedures and to assess the impact of the puncture on a possible modification of the therapeutic management. It is a single center prospective diagnostic assessment

Primary objective: To estimate the degree of agreement in diagnosis of cytologic samples from mediastinal lymph nodes obtained by Endobronchial Ultrasound (EBUS)-guided Fine Needle Capillary Sampling (FNC) versus Fine Needle Aspiration (FNA). Secondary objective: To compare the quality of cytologic samples from mediastinal lymph nodes obtained by EBUS-guided FNC versus FNA. The quality of the samples will be assessed initially by MDACC on-site cytology technicians, and then corroborated by physicians in the department of cytology. This assessment will be performed utilizing the Mair's score 3. The score consists of a 0-10 scale: 1-2= poor; 3-6=good; 7-10=superior.

Cytological diagnostic accuracy between endobronchial ultrasonography endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) samples using suction versus samples when no suction is applied.

Peripheral T cell lymphomas comprise 10-15% of all malignant lymphomas. The prognosis is significantly worse than that of aggressive B cell lymphomas. The prospects of elderly patients are especially poor, with an estimated disease free survival of only 25% after three years. Previous phase II trials have demonstrated a significant activity of the monoclonal anti CD52 antibody alemtuzumab in primary and relapsed T cell lymphoma. The investigators thus propose to investigate the value of adjuvant alemtuzumab in combination with dose dense CHOP-14 in patients with previously untreated peripheral T cell lymphoma.

Endobronchial ultrasound (EBUS) guided transbronchial needle aspiration (EBUS-TBNA) is an excellent tool for sampling enlarged mediastinal and hilar lymph nodes, but only provides needle aspirate samples which are often adequate for cytological examination only. More advanced histopathological and immunocytopathological assessment of tissue samples, which is particularly important in the diagnosis and staging of cancer, is often not possible with the small cellular samples obtained by EBUS-TBNA. A new transbronchial nodal aspiration needle (the Flex 19G EBUS-TBNA needle) has been developed with a larger needle diameter and more flexibility at the distal end, allowing better access to some lymph nodes stations. This needle can be passed down an EBUS scope and can hypothetically circumvent the deficiencies of EBUS-TBNA highlighted above by providing tissue adequate for histological assessment rather than cytological assessment alone. This study aims to establish whether the use of the Flex 19G EBUS-TBNA needle can improve the diagnostic yield of EBUS sampling procedures compared to the use of the conventional TBNA needle, thereby allowing more accurate diagnoses and reducing the need repeat procedures or more invasive surgical biopsies, without causing an increase in complication rates. Patients with enlarged mediastinal and hilar lymph nodes referred for EBUS-TBNA will be randomised to have their nodes sampled by either the EBUS-TBNA needle (conventional procedure) or the novel Flex 19G EBUS-TBNA needle. The investigators hope to recruit 250 patients over a 24 month period.

The purpose of this study is to compare the diagnosis accuracy of modified wet suction technique and 5ml dry suction technique on solid occupying lesions.
