The PRIMROSE Trial

Smoking is a major cause for developing lung cancer. People diagnosed with lung cancer, may be offered surgery which offers a complete cure. Smoking also damages the lungs and compromises a person's lung function, resulting in shortness of breath. Breathlessness limits the ability to carry out daily physical activities and exercise and makes people vulnerable to developing post procedure complications and even death. Some people with surgically treatable lung cancer have a poor ability to exercise and compromised lung function and are not fit for surgery. They will instead be referred for radiation therapy, chemotherapy or palliative care. Surgery is the preferred treatment option. The pulmonary rehabilitation program (Prehab) improves fitness levels. In addition, it improves the level of breathlessness, exercise capacity and vulnerability of people with lung cancer, with the aim of making them fit for safe surgery. By adding a breathing training device to the Prehab program, the investigators aim to further improve participants fitness for surgery, lower their risk of developing complications and the time spent in hospital after the procedure. The breathing training device is called an inspiratory muscle training device. The hand-held device helps to train and strengthen the breathing muscles, which are then able to work more effectively. After the procedure, participants may be able to breathe and exercise more easily reducing their risk of developing complications and improving outcomes. The study will compare two groups of people with lung cancer having surgical removal of part of the lung, at a specialist hospital . One group will receive standard Prehab and inspiratory muscle training with the device prior to the procedure; patients in the second group with receive standard Prehab prior to the procedure. Participants will be followed up for twelve months.
