MS 08.07 - Achieving Equitable Access to Novel Treatments for all Patients (ID 7681)

Abstract:
The UK has the highest incidence of Mesothelioma in the world with over 2700 cases diagnosed in 2014 (Cancer Research UK 2017). Data for 80% of these patients was submitted and analysed as part of the UK’s National Lung Cancer Audit Mesothelioma Report (NLCAMR) 2016 (Royal College of Physicians [RCP] 2016). The report confirmed that an increasing number of patients are receiving chemotherapy in the UK particularly patients with a good performance status; 53% compared to 41% in the audit’s 2014 report. The current audit does not identify the proportion of patients who receive their treatment as part of a clinical trial however the report recommends “All patients should be offered access to relevant clinical trials even if this requires referral outside of their network” (RCP 2016). With an increasing number of mesothelioma clinical trials now available in the UK, and more in development, facilitating seamless movement of patients from one specialist clinical team to another is essential. Mesothelioma UK, a national charity dedicated to improving outcomes for those affected by Mesothelioma, is establishing a comprehensive package of services and resources specifically to support this. The charity’s vision, for ensuring equitable access to treatment and trials is outlined in the charity’s 2016-2021 Strategy, The Next Five Years (Mesothelioma UK 2016). This presentation provides insight into readily transferable measures Mesothelioma UK has developed to support equitable access to treatment and care across the UK.

OA 02.03 - Prophylactic Irradiation of Tracts (PIT) in Patients with Pleural Mesothelioma: Results of a Multicentre Phase III Trial (ID 7980)
11:20 - 11:30 | Author(s): Liz Darlison
- Abstract
- Presentation
Background:
It has been widespread practice across Europe to irradiate diagnostic or therapeutic chest wall (CW) intervention sites in patients with malignant pleural mesothelioma (MPM) post-procedure - a practice known as prophylactic irradiation of tracts (PIT). This study aims to determine the efficacy of PIT in reducing the incidence of CW metastases following a chest wall procedure in MPM.
Method:
In this multicentre phase III randomised controlled trial, MPM patients following a chest wall procedure were randomised 1: 1 to receive PIT (within 42-days of procedure) or no PIT. Large thoracotomies, needle biopsy sites and indwelling pleural catheters were excluded. PIT was delivered at a dose of 21Gy in 3 fractions over 3 consecutive weekdays using a single electron field adapted to maximise coverage of the tract from skin surface to pleura. The primary outcome was the incidence of CW metastases within 6 months from randomisation, assessed in the intention-to-treat population. Stratification factors included epitheloid histology and intention to give chemotherapy. Trial registration number NCT01604005.
Result:
375 patients (186 PIT and 189 no PIT) were randomised between 06/2012-12/2015 from 54 UK centres. Comparing PIT vs no PIT, %male patients was 89.8/88.4%, median age 72.8/74.6 years, %ECOG PS (0,1,2) 32.2,56.5,11.3/23.8,56.1,20.1%, %confirmed epithelioid histology 79.6/74.1%, and %with intention to give chemotherapy 71.5/71.4%. The chest wall procedures were VATS (58.1/51.3%), open surgical biopsy (2.7/5.3%), local-anaesthetic-thoracoscopy (26.9/27.0%), chest drain (5.9/8.5%) and others (6.5/7.9%) for the PIT vs no PIT arm respectively. Radiotherapy was received as intended by 181/186 patients in the PIT arm. The proportion of CW metastases by 6 months was 6/186 (3.2%) vs 10/189 (5.3%) for the PIT vs no PIT arm respectively (odds ratio 0.60 [95% CI 0.17-1.86]; p=0.44) and by 12 months 15/186 (8.1%) versus 19/189 (10.1%) respectively (OR=0.79 [95% CI 0.36-1.69];p=0.59). Cumulative incidence of CW metastases at 6months/12 months/24 months was 3.3/8.5/10.0% in the PIT arm vs 5.6/10.9/18.7% in the no PIT arm. Evaluable patients who developed CW metastases reported a mean increase in visual analogue scale pain score of 13.3 (p<0.01) compared to baseline. Skin toxicity was the most common radiotherapy-related adverse event in the PIT arm with 96(51.6%) grade 1, 19(10.2%) grade 2, and 1(0.5%) grade 3 radiation dermatitis (CTCAE V4.0). There were no other grade 3 or higher radiotherapy-related adverse events.
Conclusion:
There is no role for the routine use of PIT following diagnostic or therapeutic CW procedures in patients with MPM.
