    Background
    

    Non-small cell lung cancer (NSCLC) represents over 80% of lung tumours. If diagnosed early, treatment is surgical with curative intent. The addition of postoperative cisplatin-based chemotherapy has demonstrated a significant survival advantageand is generally accepted as a standard treatment in patients of good performance status.

    Despite this, risk of relapse remains high and current ESMO (2017) guidance suggests ‘NSCLC patients treated with radical intent should be followed for treatment-related complications, detection of treatable relapse or occurrence of second primary lung cancer. Recommendations for surveillance, include regular review, physical exam and imaging. This should be tailored to suitability of individual patients for further intervention. Local practice mandates a chest x-ray (CXR) with CT and/or PET follow-up of anomalies.

    Between January 2004 and May 2017 165 patients underwent surgical resection for Stage 1B-IIIA NSCLC. We identified all patients within this cohort with radiological evidence of thoracic recurrence who had relapsed following postoperative chemotherapy. Electronic patient care records were used for data collection. Patient characteristics, surveillance modalities and overall survival (OS) from date of diagnosis to first relapse were analysed. Imaging modalities detecting recurrence and OS were determined using Kaplan-Meier methodology (SPSS).

    89 patients were identified, the median age was 62 years (range 42-77 years). Patients underwent surveillance initially every 3 months following completion of postoperative chemotherapy. Median time to relapse was 25.6 months (range 0.53 to 50.9 months). 62 patients (69.7%) had radiological confirmed evidence of disease recurrence. 4 (6.5%) had relapsed with extra-thoracic recurrence. 28 patients (45.2%) had confirmed intra thoracic disease recurrence on CXR despite chest CT imaging performed at designated time intervals. However, 27 patients (43.5%) that underwent surveillance with CXR had confirmed intra thoracic disease recurrence with chest CT imaging. Median OS for CXR detected recurrence was 27.5 months (range 6.5 – 99.1 months) and 27.45 months (range 5.9 to 104.2 months) for chest CT detected recurrence (p-value 0.46).

    There is a paucity evidence specifically around the follow-up and surveillance modalities aimed at detecting relapse to improve survival after curative intent therapy in NSCLC.Our data demonstrate that 3 monthly CXR is an appropriate surveillance modality for initial detection of intra-thoracic disease recurrence.
