The Interventional Pulmonary Medicine Program was started in 2001 by Dr. Alain Tremblay. There are currently seven respirologists who are members of the group – they play a key role in the Alberta Thoracic Oncology Program (ATOP) and the Dyspnea Clinic (Malignant Pleural Effusions).
ATOP supports responsive diagnosis, staging ad investigation of suspected lung malignancies. To accomplish this a team of radiologists, respirologists, thoracic surgeons, nurse practitioners and clerks work together to evaluate this patient group. Referrals are received and reviewed by a nurse practitioner who initiates the intake of information and preliminary evaluation of patients who are then booked into the clinic to be seen by our interdisciplinary team.
An optimal diagnosis and staging plan for our patients is determined as well as preliminary therapeutic plans discussed including involvement in clinical trials, in collaboration with the Thoracic Surgery and Lung Tumour Group oncologists.
Patients have full access to all lung cancer diagnostic and staging modalities including standard radiology, bronchoscopy with transbronchial needle aspiration of mediastinal lymph nodes (with endobronchial ultrasound), CT guided transthoracic needle aspiration, mediastinoscopy, PET scanning, fine needle aspiration of superficial lymph nodes, thoracentesis, closed needle pleural biopsy and thoracoscopy.
As well, expedited pre-op evaluation of pulmonary function with full pulmonary physiologic testing, differential VQ scanning and cardiopulmonary exercise testing are readily available.
