Objective:сonstructive principles development of early diagnosis of bone and cerebral metastases of peripheral non-small cell lung cancer (PNSCLC), is based on the targeted preventive and personalized application of radiological and nuclear diagnostic methods.Materials and methods.There was performed the retrospective analysis of medical cards of 1473 patients with peripheral non-small cell lung cancer for the evaluation of the characteristics and frequency of bones and brain metastases. The frequency and features of bone and brain metastases depending on clinical and morphological features of the primary lung tumor were studied. 118 patients with PNSCLC with bone and brain metastases, regardless of clinical symptoms, were examined using a wide range of modern radiological and nuclear methods.Conclusion:the original algorithm has been developed on the study of the diagnostic significance of medical imaging methods. The application of this algorithm will significantly improve the early diagnosis of bone and cerebral metastases and improve the staging of PNSCLC.

Patients with small cell lung cancer (SCLC) are at significant risk of developing brain metastases during their disease course. Prophylactic cranial irradiation (PCI) has been incorporated into SCLC treatment guidelines to diminish the risk of developing brain metastases. In 2007, a randomized trial suggested that PCI decreases the incidence of brain metastases and prolongs overall survival (OS) in patients with extensive-stage SCLC (ES-SCLC) who have responded to initial therapy. However, this study did not include modern central nervous system imaging with CT or MRI prior to randomization. A more recent Japanese trial with MRI staging and surveillance demonstrated that PCI diminished the incidence of brain metastases but did not improve survival. This review examines the largest clinical studies, controversies, and future directions of PCI in patients with ES-SCLC.

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.
