Introduction Survival after a diagnosis of brain metastasis in non-small-cell lung cancer (nsclc) is generally poor. We previously reported a median survival of approximately 4 months in a cohort of patients treated with whole-brain radiotherapy (wbrt). Since that time, we implemented a program of stereotactic radiosurgery (srs). In the present study, we examined survival and prognostic factors in a consecutive cohort of patients after the introduction of the srs program.Methods Data from a retrospective review of 167 nsclc patients with brain metastasis referred to a tertiary cancer centre during 2010–2012 were compared with data from a prior cohort of 91 patients treated during 2005–2007(“pre-srs cohort”).Results Median overall survival from the date of diagnosis of brain metastasis (4.3 months in the srs cohort vs. 3.9 months in the pre-srs cohort, p = 0.74) was not significantly different in the cohorts. The result was similar when the no-treatment group was excluded from the srs cohort. Within the srs cohort only, significant differences is overall survival were observed between treatment groups (srs, wbrt plus srs, wbrt, and no treatment), with improved survival being observed on univariate and multivariate analysis for patients receiving srs compared with patients receiving wbrt alone (p < 0.001).Conclusions No improvement in survival was observed for nsclc patients with brain metastases after the implementation of srs. Selected patients (younger age, female sex, good performance status, fewer brain metastases) treated with srs appeared to demonstrate improved survival. However, those observations might also reflect better patient selection for srs or a greater tendency to offer those patients systemic therapy in addition to srs.

8539 Background: ECOG-ACRIN E1505 was a phase III randomized trial of adjuvant chemotherapy with or without bevacizumab for patients with completely-resected Stage IB (>4CM) – IIIA non-small cell lung cancer. Prior studies have shown that the risk of brain recurrence in patients after definitive surgical resection is approximately 10%; however, covariates associated with development of brain recurrence have varied across these studies. We sought to estimate the incidence of and risk factors for brain recurrence. Methods: Among the 1501 patients enrolled to ECOG-ACRIN E1505, 121 patients developed brain metastases as their first site of recurrence and are the subject of this investigation. All 1501 patients underwent a pneumonectomy (N = 192) or (bi)lobectomy and had an R0 resection. The cumulative incidence of brain recurrence was estimated after adjusting for recurrence at other sites and death as competing events. A multivariable regression model was fitted using the methodology of Fine and Gray to evaluate the effect of covariates on the subdistribution of brain recurrence. Results: With a median follow-up of 50.3 months, a total of 121 brain metastases had been reported as the first site of recurrence. The incidence of brain recurrence at 12 months post-randomization was 3.7% (95% CI: 2.8% – 4.7%), and it increased to 8.5% (95% CI: 7.0% - 10.0%) at 3 years, and to 9.9% (95% CI: 8.0% - 11.7%) at 6 years. Risk factors for brain metastases included pneumonectomy(HR=1.8; p=0.01), and nonsquamous histology(HR=2.04; p=0.003), but bevacizumab(HR=0.64; p=0.02) was associated with potentially protective effect. Conclusions: The cumulative incidence of brain recurrence increased over time to 9.9% at 6 years in this population of patients with surgically-resected non-small cell lung cancer. Treatment, tumor histology, and type of resection appear to be associated with the risk of brain recurrence. Clinical trial information: NCT00324805.

8560 Background: Although thoracic twice-daily radiotherapy (TDRT) is one of standards of care for small cell lung cancer, its impact on brain metastases remains unknown. This study aimed to compare TDRT with once-daily radiotherapy (ODRT) for the brain metastases rate after prophylactic cranial irradiation in patients with small cell lung cancer. Methods: Consecutive patients received TDRT (45Gy/30f)/ODRT(50-66Gy/25-33f), chemotherapy and prophylactic cranial irradiation were retrieved from eight hospitals’ databases between 2003 and 2016. The endpoints included brain metastases, progression-free survival and overall survival. Brain metastases rate was evaluated using competing risk analysis. A 1:1 propensity score matching approach was used to control confounding between these two groups. Confounding covariates included eight demographic variables and eight treatment related covariates. Results: Of the 778 eligible patients with median age of 55-year (IQR, 48-61), 204 (26.2%) were female. At a median follow-up time of 23.6 months (IQR, 14.2- 38.2), 131 (16.8%) experienced brain metastases. The rates in TDRT were significantly higher than ODRT (3-year, 26.0% vs. 16.9%; HR = 1.55, 95%CI 1.06-2.26, P = 0.03). Of the 338 matched patients (169 in ODRT vs. 169 in TDRT), 60 (17.8%) experienced brain metastases with 3-year rate of 14.9% in ODRT vs 26.0% in TDRT (HR = 1.71, 95%CI 1.02-2.88, P = 0.04). Progression-free survival was similar in both the whole cohort and the matched one. Overall survival in ODRT tended to be significantly longer after matching (median, 47.2 months in ODRT vs. 32.8 months in TDRT; HR = 1.41, 95%CI 0.99-2.01, P = 0.06). When jointly evaluated biologically effective dose (BED), start of any therapy to the end of radiotherapy (SER) and TDRT/ODRT in the multivariable analysis, the impact of ODRT/TDRT on overall survival become more significant (HR = 1.69, 95%CI 1.05-2.71, P = 0.03). Conclusions: Patients with small cell lung cancer who were treated with thoracic TDRT appeared to have higher risk of brain metastases than those with ODRT, which strongly supports the need for further prospective randomized clinical trials, especially in China or other parts of Asia.

Abstract Background Dissociated responses (DR) are phenomena in which some tumors shrink, whereas others progress during treatment of patients with cancer. The purpose of the present study was to evaluate the frequency and prognosis of DR in non-small cell lung cancer (NSCLC) patients treated with anti-program cell death-1/ligand 1 (anti-PD-1/L1) inhibitors. Methods This retrospective study included NSCLC patients who received anti-PD-1/L1 inhibitor as second- or later-line treatment. We excluded patients without radiological evaluation, including brain imaging within 28 days prior to the treatment, and those without measurable lesions. We evaluated all measurable lesions in each organ. We defined DR as a disease with some shrinking lesions as well as growing or emerging new lesions in patients who showed progressive disease (PD), according to the RECIST 1.1 at the initial CT evaluation. Cases not classified as DR were defined as ‘true PD’. Overall survival was compared between patients with DR and those with true PD using Cox proportional hazards models. Results The present study included 62 NSCLC patients aged 27–82 years (median: 65 years). DR and true PD were observed in 11 and 51 patients, respectively. Nivolumab, pembrolizumab, and atezolizumab were administered to 45, 7, and 10 patients, respectively. Median overall survival was significantly longer in patients with DR versus true PD (14.0 vs. 6.6 months; hazard ratio for death: 0.40; 95% confidence interval: 0.17–0.94). Conclusions The frequency of DR in NSCLC patients who showed PD to anti-PD-1/L1 was 17.7%. Patients with DR exhibited a relatively favorable prognosis.
