e13030 Background: In patients (pts) with non-small cell lung cancer (NSCLC), it is unknown whether pts with bone metastases are predisposed to the development of brain metastases. The impact of bevacizumab (Bev) on the development of bone and brain metastases is not fully characterized. Methods: Retrospective review of pts with stage IV NSCLC without brain metastasis at diagnosis was undertaken. The primary endpoint was to determine whether the development of bone metastases is predictive of the development of brain metastases. Secondary endpoints involved the proportion of pts who developed brain and/or bone metastases while being treated with Bev. Data were analyzed using competing risks methods. Results: A total of 175 pts (52% males, median (range) age: 60 y (35-80)) were studied. Of whom 79% received Bev and 21% did not receive Bev as part of their treatment. Overall 34% of pts had bone metastases at the start of therapy. Pts with pre-existing bone metastases tended to develop new bone disease more frequently than pts who did not initially have bone metastases (39% vs. 19%, p =. 01). The incidence of the development of brain metastases among pts who had pre-existing bone metastases was 17% vs.16 % in pts without pre-existing bone metastases. However, the incidence of brain metastases among pts with pre-existing bone disease who developed new bone metastases was 33% vs. 6% in pts who did not develop new bone disease but had pre-existing bone metastases. Adjusting for initial bone disease, development of new bone metastases was associated with a shorter brain metastases-free interval HR 5.06 (2.03-12.65; p = 0.005). In a subgroup analysis based on Bev exposure, the likelihood of developing brain and bone metastases within 2 years of starting Bev was estimated to be 25% and 27%, respectively, while the likelihood of developing brain and bone metastases without Bev treatment was 33% and 43 %, respectively. Conclusions: In pts with NSCLC, the development of new bone metastases may be indicative of the subsequent development of brain metastases. Additionally, Bev therapy may have an effect on the development of both bone and brain metastases. A prospective investigation may be warranted.

In a study of 411 patients with small-cell lung cancer (SCLC) entered on therapeutic clinical trials between 1973 and 1987, we analyzed whether changes in the prognostic importance of pretreatment factors had occurred during the 14-year time period. After adjusting for other prognostic factors, brain involvement was associated with shorter survival in patients treated before December 1979 (P = .024) but not in patients treated thereafter (P = .54). The patients diagnosed before 1979 had brain metastases documented by radionuclide scan while computed cranial tomography (CCT) was more commonly used after 1979. Patients who had brain metastases diagnosed by radionuclide scan lived a shorter period of time than patients who had the diagnosis made by the more sensitive CCT scan (P = .031). In contrast, Cox proportional hazards modeling showed that liver metastases in patients were associated with shorter survival in patients treated after 1979 (P = .0007) but not in patients treated before then (P = .30). A larger proportion of patients had a routine liver biopsy before 1979 than after 1979 when more patients had the liver staged with less sensitive imaging studies and biochemical parameters. Patients with SCLC whose cancer was confined to the thorax but had medical or anatomic contraindications to intensive chest radiotherapy had similar survival compared with patients with limited-stage SCLC who were treated with combination chemotherapy alone (P = .68). From these data we conclude: (1) the sensitivity of the staging procedures used can affect the impact on survival of cancer involvement of a given site; and (2) patients with cancer confined to their chest with medical or anatomic contraindications to chest radiotherapy do not have a shorter survival than patients with limited-stage disease treated with chemotherapy alone.

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.

Abstract Background Molecular and genetic alterations of non-small-cell lung cancer (NSCLC) now play a vital role in patient care of this neoplasm. The authors focused on the impact of epidermal growth factor receptor mutation (EGFR-mt) status on the survival of patients after brain metastases (BMs) from NSCLC. The purpose of the study was to understand the most desirable management of BMs from NSCLC. Methods This was a retrospective observational study analyzing 647 patients with NSCLC, including 266 patients with BMs, diagnosed at our institute between January 2008 and December 2015. EGFR mutation status, overall survival (OS) following diagnosis, OS following BMs, duration from diagnosis to BMs, and other factors related to OS and survival after BMs were measured. Results Among 647 patients, 252 (38.8%) had EGFR mutations. The rate and frequency of developing BMs were higher in EGFR-mt patients compared with EGFR wildtype (EGFR-wt) patients. EGFR-mt patients showed longer median OS (22 vs 11 months, P < .001) and a higher frequency of BMs. Univariate and multivariate analyses revealed that good performance status, presence of EGFR-mt, single BM, and receiving local therapies were significantly associated with favorable prognosis following BM diagnosis. Single metastasis, compared with multiple metastases, exhibited a positive impact on patient survival after BMs in EGFR-mt patients, but not in EGFR-wt NSCLC patients. Conclusions Single BM with EGFR-mt performed better than other groups. Furthermore, effective local therapies were recommended to achieve better outcomes.

Abstract We conducted a large, multicenter, retrospective survey aimed to explore the impact of tumor bone involvement in Non-Small Cell Lung Cancer.Data on clinical-pathology, skeletal outcomes and bone-directed therapies for 661 deceased patients with evidence of bone metastasis were collected and statistically analyzed. Bone metastases were evident at diagnosis in 57.5% of patients. In the remaining cases median time to bone metastases appearance was 9 months. Biphosphonates were administered in 59.6% of patients. Skeletal-related events were experienced by 57.7% of patients; the most common was the need for radiotherapy. Median time to first skeletal-related event was 6 months. Median survival after bone metastases diagnosis was 9.5 months and after the first skeletal-related event was 7 months. We created a score based on four factors used to predict the overall survival from the diagnosis of bone metastases: age >65 years, non-adenocarcinoma histology, ECOG Performance Status >2, concomitant presence of visceral metastases at the bone metastases diagnosis. The presence of more than two of these factors is associated with a worse prognosis.This study demonstrates that patients affected by Non-Small Cell Lung Cancer with bone metastases represent a heterogeneous population in terms of risk of skeletal events and survival.
