Scientific title | A phase III randomised trial of prophylactic irradiation of tracts in patients with malignant pleural mesothelioma following invasive chest wall intervention |
Study acronym | PIT |
Study objectives | The PIT (Prophylactic Irradiation of Tracts) trial will determine the efficacy, as assessed by the incidence of chest wall metastasis, of PIT following invasive chest wall intervention in malignant pleural mesothelioma compared to no prophylactic radiotherapy. Patients will be randomised on a 1:1 basis to receive PIT or No PIT. The trial is a phase III multi-centre trial that aims to recruit 374 patients across the UK. After randomisation PIT patients will receive 21 Gy over 3 fractions. All patients will be followed up for a total of 52 weeks with regular clinic visits and then followed up over the phone. The primary endpoint is Incidence of chest wall tract metastasis 6 months from randomisation. The secondary endpoints are: time from randomisation to chest wall metastasis; position of metastasis in relation to radiation field for PIT patients; acute and late skin toxicity for PIT patients; and pain from chest wall metastasis evaluated using the Visual Analogue Scale (VAS) pain score |
Ethics approval(s) | Greater Manchester West Ethics Committee, 04/04/2012, ref: 12/NW/0249 |
Health condition(s) or problem(s) studied | Lung Cancer, Mesothelioma |
Intervention | Patients who meet the eligibility criteria will be randomised to PIT or No PIT. The PIT patients will receive radiotherapy at 21 Gy in 3 fractions to the intervention (surgery) site. Chemotherapy on both arms is optional. Follow up is for 2 years on both arms (or until chest wall recurrence or death) and includes regular telephone follow up and for the first year patients coming in to the hospital regularly as outpatients. |
Intervention type | Other |
Primary outcome measure | Efficacy as assessed by the incidence of chest wall metastasis |
Secondary outcome measures | 1. Toxicity of PIT 2. Time to chest wall metastasis in patients undergoing PIT as compared to no radiotherapy 3. Pain from chest wall metastasis |
Overall study start date | 30/05/2012 |
Completion date | 30/06/2015 |

Participant type(s) | Patient |
---|---|
Age group | Adult |
Lower age limit | 18 Years |
Sex | Both |
Target number of participants | Planned Sample Size: 374; UK Sample Size: 374 |
Key inclusion criteria | 1. Either sex, age = 18 year 2. Diagnosis of mesothelioma by MDT 3. All histological subtypes. Where the histological diagnosis is unclear, a specialist thoracic pathologist should be consulted. 4. ECOG performance status 0-2. 5. Inoperable disease or operable disease in patients unsuitable for surgery as decided by a MDT. 6. Chest wall intervention with video-assisted thoracoscopy (VATS), open surgical biopsy, local anaesthetic thoracoscopy or chest drain. 7. Able to start radiotherapy within 42 days (6 weeks) from most recent chest wall intervention. 8. Chest wall intervention scar visible at time of randomisation. 9. No indwelling pleural catheters in-situ at the intervention site 10. RT target volume acceptable by the local radiotherapist. 11. No previous open thoracotomy. 12. No previous radiotherapy to the region of the chest wall intervention site. 13. Not currently receiving chemotherapy and not received chemotherapy for mesothelioma before randomisation 14. No other previous or concomitant illness or treatment which in the opinion of the clinician will interfere with the trial treatments or comparisons. 15. Patients enrolled on other clinical trials could be considered after discussion with the chief investigators. 16. Female patients must satisfy the investigator that they are not pregnant, or are not of childbearing potential, or are using adequate contraception. 17. Patients must not be breastfeeding 18. Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the trial protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial 19. Before patient registration/randomisation, written informed consent must be given according to ICH/GCP, and national/local regulations. 20. Patients can only be randomised in this trial once. |
Key exclusion criteria | 1. Patients who underwent a thoracotomy (as large thoracotomy scars may not be adequately covered by this radiotherapy technique) 2. Previous radiotherapy to the region of the chest wall intervention site 3. Patients currently receiving chemotherapy |
