How much primary tumor metabolic volume reduction is required to improve outcome in stage III NSCLC after chemoradiotherapy? A single-centre experience

How much primary tumor metabolic volume reduction is required to improve outcome in stage III... Purpose We analysed a correlation between pre- to post-treatment primary tumour metabolic volume (PT-MV) reduction on 18F- FDG-PET/CT and survival in non-small cell lung cancer (NSCLC) patients treated with chemoradiotherapy (CRT). Methods Sixty consecutive patients with NSCLC stage IIIA-B (UICC 7th edition), treated with chemoradiotherapy, who underwent 18F-FDG-PET/CT at the same institution before and 6 weeks after treatment, were analysed. Different metabolic response values were investigated on their correlation with survival parameters: complete response (100% PT-MV reduction); major response (80–99% PT-MV reduction); moderate response (50–79% PT-MV reduction); minor response (1–49% PT-MV reduction) and non-response (no change or increase in uptake). Results From 60 patients, 52 (87%) had repeat PET/CT scans 6 weeks after completion of CRT. Complete metabolic response (CR) was reached in ten (17%), whereas major and moderate metabolic responses occurred in 16 (27%) and 15 (25%) patients, respectively. Four patients (7%) had minor metabolic response. Non-response was documented in seven patients (12%). Median overall survival (MS) for the entire cohort was 17 months (95% CI: 11.9–22.1 months). MS according to the different metabolic response values was as follows: 34 months (95% CI: 0–84.1); 22 months (95% CI: 14.2–29.8); 12 months (95% CI: 0.4–23.6); 11 months (95% CI: http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png European Journal of Nuclear Medicine and Molecular Imaging Springer Journals
