The smoking history revealed that 11 (27.5%) patients were never smokers, 28 (70.0%) were current or former smokers, and the smoking history of 1 (2.5%) patient was unknown. Adenocarcinoma was diagnosed in all patients. Mutations in the epidermal growth factor receptor (EGFR) and Kirsten rat sarcoma oncogene 2 (KRAS) were detected in 7 and 6 patients, respectively, and anaplastic lymphoma kinase (ALK) rearrangement was identified in 3 patients.\u003C\/p\u003E\u003Cp id=\u0022p-6\u0022\u003EThe patient cohort had a poor prognosis. The median time to development of brain metastasis was 7.5 months (range, 0 to 65) from the diagnosis of non-Sq NSCLC.

Patients received bevacizumab for a median 5.1 months (range, 0.7 to 35 months). The median delay was 6 months (range, 0.1 to 61.1) between the diagnosis of brain metastases and the delivery of WBRT, while the median delay between the last dose of bevacizumab and WBRT was 38 days (range, 0 to 167).\u003C\/p\u003E\u003Cp id=\u0022p-8\u0022\u003EDr. Arrondeau said that this study suggested that the efficacy of WBRT is unaffected by prior bevacizumab.\u003C\/p\u003E\u003Cp id=\u0022p-9\u0022\u003EFollowing WBTR, 2 patients achieved complete response, 12 patients showed partial response, 15 showed stable disease, and 7 patients experienced disease progression.

Leptomeningeal progression was observed in 9 (22.5%) patients at a median of 1.7 months following WBRT (range, 0.03 to 10).

Following WBRT, 10 patients were asymptomatic, 12 patients experienced improvement, 7 patients had the same symptoms, 9 patients experienced worsening symptoms, and 2 patients were lost to follow-up or had died.\u003C\/p\u003E\u003Cp id=\u0022p-12\u0022\u003EThe most common side effects were intracranial hypertension symptoms, reported by 6 patients (1 grade 2, and 5 grade 3), 2 patients experienced grade 2 seizures, 1 patient reported grade 3 vertigo, 1 had grade 3 dizziness, and 2 patients reported grade 2 intracranial bleeding.\u003C\/p\u003E\u003Cp id=\u0022p-13\u0022\u003EA recent Phase 3 study conducted by the European Organisation for Research and Treatment of Cancer comparing patients with 1 to 3 brain metastases of NSCLC who were assigned randomly to receive either WBRT or observation following complete surgery or radiosurgery showed that overall survival was similar in the two arms (median, 10.9 vs 10.7 months, respectively; p=.89). However, the 2-year relapse rate with WBRT was decreased compared to observation, both at initial sites (surgery: 59% to 27%, p\u0026lt;0.001; radiosurgery: 31% to 19%, p=0.040) and at new sites (surgery: 42% to 23%, p=0.008; radiosurgery: 48% to 33%, p=0.023). WBRT also decreased the rates of death from intracranial progression, which occurred in 78 (44%) of 179 patients in the observation arm and in 50 (28%) of 180 patients in the WBRT arm [Kocher M et al. \u003Cem\u003EJ Clin Oncol\u003C\/em\u003E 2009]. However, the quality-of-life scores reported by patients in the observation group of the same trial were significantly higher on several subscales over 3 time points ending at 1 year [Soffietti R et al. \u003Cem\u003EJ Clin Oncol\u003C\/em\u003E 2013].\u003C\/p\u003E\u003Cp id=\u0022p-14\u0022\u003EAccording to Dr. Arrondeau, WBRT could be safely administered to patients with brain metastases within 6 months of having received bevacizumab for NSCLC, but she cautioned that these findings were compromised by the small sample size of the study and should be confirmed in a larger prospective study.\u003C\/p\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2014 MD Conference Express\u00ae\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/14\/3\/12.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzpasp\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
