Abstract
Background The development of brain metastases is a common problem in patients diagnosed with non-small cell lung carcinoma (NSCLC). Technological advances in surgery and radiotherapy have allowed greater local control. Moreover, the emergence of targeted therapies and immunotherapy with greater activity on the central nervous system than classical chemotherapy have given way to new strategies in the treatment of brain metastases. We review the current role of local treatments, surgery and radiotherapy, and the most effective combination strategies with the new systemic treatments. Relevance for patients Brain metastases frequently occur during the course of NSCLC. In recent years, a range of treatments have appeared, such as targeted treatments or immunotherapy, with greater activity at the brain level than classical chemotherapy. Radiotherapy treatment is also now much more conformal and ablative doses can be delivered to the volume of the metastatic area, providing greater local control and less neurological toxicity. However, surgery is still required in cases where anatomopathological specimens are needed and when compressive effects appear. An important challenge is how to combine these treatments to achieve the best control and minimise patients' neurological impairments, especially because of limited experience with the new target drugs, and the unknown toxicity of the different combinations. Future research should therefore focus on these areas in order to establish the best strategies for the treatment of brain metastases from non-small cell lung cancer. Core tips In this work, we intend to elucidate the best therapeutic options for patients diagnosed with brain metastases of NSCL, which include: surgery, WBRT, radiosurgery or systemic treatment, and the most effective combinations and timings of them, and the ones with the lowest associated toxicity.

Abstract
Background Superior sulcus tumors, or Pancoast tumors, are challenging thoracic malignancies to treat due to their anatomical location posing difficult surgical access and potential involvement of adjacent vital structures. The current standard of care is trimodality treatment, which consists of induction chemoradiotherapy followed by radical surgical resection. This study aims to report the clinical outcomes of trimodality approach in British Columbia, Canada. Methods Patients with Pancoast tumors who underwent trimodality treatment between 2000–2015 were included in this provincial multi-center retrospective study. Patient-, disease-, and treatment-related data were collected, and treatment outcomes were recorded. Results We identified 32 patients who underwent induction chemoradiotherapy and subsequent surgical resection. Mean age was 59 (43–75 years) with median follow-up of 43 months (5–216 months). Complete resection was achieved in 31 patients (97%). Fourteen patients (44%) had pathological complete response after induction chemoradiotherapy. Thirteen (41%) showed minimal microscopic (>90% tumor necrosis) and 5 (16%) macroscopic residual disease (<90% tumor necrosis). Fourteen patients (44%) developed recurrence, which was distant in 9 cases. The 2-, 5-, and 10-year overall survival rates were 67.9%, 50.1%, 31.8% and the 2-, 5-, and 10-year disease-free survival rates were 65.1%, 47.1% and 28.2% respectively. There were no statistically significant differences in overall survival or disease-free survival rates with or without pathological complete response. Conclusions Complete surgical resection with negative margins can be achieved after induction chemoradiotherapy, and curative-intent trimodality treatment can lead to long-term survival in some patients. This study did not demonstrate any prognostic value of pathological complete response, likely due to small sample size.

Abstract
Background Brain metastasis (BM) is a very serious event in patients with breast cancer. The aim of this study was to establish a nomogram to predict the risk of BM in patients with de novo stage IV breast cancer. Methods We gathered female patients diagnosed with de novo stage IV breast cancer between 2010 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database. After randomly allocating the patients to the training set and verification set, we used univariate and multivariate logistic regression to analyze the relationship between BM and clinicopathological features. Finally, we developed a nomogram which was validated by the analysis of calibration curve and receiver operating characteristic curve. Results Of 7,154 patients with de novo stage IV breast cancer, 422 developed BM. Age, tumor size, subtype, and the degree of lung involvement were significantly correlated with BM. The nomogram had discriminatory ability with an area under curve (AUC) of 0.640 [95% confidence interval (CI): 0.607 to 0.673] in the training set, and 0.644 (95% CI: 0.595 to 0.693) in the validation set. Conclusions Our study developed a nomogram to predict BM for de novo stage IV breast cancer, thus helping clinicians to identify patients at high-risk of BM and implement early preventive interventions to improve their prognoses.

Abstract
In non-small cell lung cancer (NSCLC) brain metastases (BM) will affect up to 50% of patients during whole disease period. BM themselves impact heavily not only on patient’s prognosis but also are a source of symptoms aggravating quality of life. Standard (pemetrexed), and non-standard chemotherapy (temozolomide) in patients with NSCLC failed to prevent them from BM. In terms of systemic treatment there are promising results showed when durvalumab (PACIFIC study), osimertinib (FLAURA trial) or alectinib (JALEX study) was used. However, those substances are effective only in small cohort with ALK or EGFR alterations. Prophylactic cranial irradiation (PCI) as a non-specific treatment has proven to be a powerful tool in preventing BM without affecting overall survival in neither way. That has been proved in nearly all earlier and all recent studies—NVALT11/DLCRG-02, RTOG 0214 update, Li et al. The positive effect of BM incidence reduction may draw fear form PCI usage due to potential cognitive toxicity the PCI may cause. Results of recent trials show that after PCI only mild cognitive disorders (MCD) may arise. Promising results in terms of reducing MCD are shown when memantine is used or/and hippocampal avoidance techniques are implemented. HA in PCI seem to be cost effective but calculations were made on small-cell lung cancer cohorts. Still even recent studies did not clarify finally which patients could benefit from PCI or other forms of preventing BM. It seems that new trials should focus on younger, fit and non-squamous histology patients and use the tests for mild cognitive disorders (MoCA, BHA) rather than screening tests for dementia (MMSE, HVLT, ADL). The main obstacle in performing new trials on PCI in NSCLC cohorts may be, however, patients’ accrual, as a difficulty which occurred during latest trials.

Prophylactic Cranial Irradiation in Patients With High-Risk Metastatic Non-Small Cell Lung Cancer: Quality of Life and Neurocognitive Analysis of a Randomized Phase II Study. Int J Radiat Oncol Biol Phys 2021; 111:81-92. [PMID: 33915217 DOI: 10.1016/j.ijrobp.2021.04.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/31/2021] [Accepted: 04/14/2021] [Indexed: 01/05/2023]
Abstract
PURPOSE To this date, studies regarding the use of prophylactic cranial irradiation (PCI) versus standard of care (SoC) for patients with non-small cell lung cancer have shown limited benefit in survival outcomes, in addition to the potential effects on quality of life (QoL) and neurocognitive function (NCF). This randomized, phase II study evaluated the role of PCI in QoL and NCF, in a population comprised of subjects at a high risk for development of brain metastases (BM). METHODS AND MATERIALS Eligible patients had histologically confirmed non-small cell lung cancer without baseline BM, harboring epidermal growth factor receptor mutations, anaplastic lymphoma kinase rearrangements, or elevated carcinoembryonic antigen (CEA) at diagnosis. Participants were assigned to receive SoC or SoC plus PCI (25 Gy in 10 fractions). Primary endpoint was BM at 24 months (BM-24), for which the study was powered. Secondary endpoints included QoL assessed using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and the Lung Cancer module (LC13) and NCF assessed using the Mini Mental State Examination (MMSE). Patients were followed every 3 months for a year for QoL and NCF. RESULTS From May 2012 to December 2017, 84 patients were enrolled in the study, 41 were allocated to PCI while 43 received SoC. Efficacy outcomes are discussed in a separate article. The global health-QoL scores were similar at 3, 6, 9, and 12 months after randomization between both study arms, with no significant differences when comparing by groups. At 1-year postrandomization, median global health QoL scores were 83 (p25-p75: 75-83) and 83 (p25-p75: 75-83) in the control and experimental arms, respectively. There were no significant changes in terms of the mean differences between subjects in either study arm when analyzing the change between baseline and 12-month scores (16.4 ± 19.9 vs 12.9 ± 14.7; P = .385). Seventeen patients were alive at database lockdown in February 2020, without significant differences in median MMSE (30 [p25-75: 29-30] vs 30 [p25-75: 28-30]) or QLQ-C30 scores (75.0 [p25-75: 50-87.2] vs 67.0 [p25-75: 50.0-100.0]). CONCLUSIONS Among a selected high-risk population for developing BM, PCI did not significantly decrease QoL or neurocognitive function as assessed using the MMSE. Future studies are warranted to assess this observation, using more varied and sensitive tools available to date.

Risk of development of brain metastases according to the IASLC/ATS/ERS lung adenocarcinoma classification in locally advanced and metastatic disease. Lung Cancer 2021; 155:183-190. [PMID: 33558063 DOI: 10.1016/j.lungcan.2021.01.023] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2020] [Revised: 11/23/2020] [Accepted: 01/23/2021] [Indexed: 01/01/2023]
Abstract
INTRODUCTION Brain metastases (BM) are frequent among lung cancer patients, affecting prognosis and quality of life. The International Association for the Study of Lung Cancer (IASLC), American Thoracic Society (ATS) and European Respiratory Society (ERS) lung adenocarcinoma (LADC) classification (IASLC/ATS/ERS) has prognostic impact in early-stage disease; however, its role in the advanced setting is not precise. This study aims to determine the correlation between the predominant histological subtype and the risk of developing brain metastases (BM) in locally advanced and metastatic (stages IIIB-IV) LADC. METHODS A total of 710 patients with LADC were treated at our institution from January 2010 to December 2017. After excluding patients with brain metastases at diagnoses (n = 151), they were categorized according to the IASLC/ATS/ERS LADC classification to estimate the risk of developing brain metastases. A competing risk analysis was employed, considering death a competing risk event. RESULTS From 559 patients, the mean age was 59 ± 13.2 years, women (52.4 %), and clinical-stage IV (79.2 %). LADC subtypes distribution was lepidic (11.6 %), acinar (37.9 %), papillary (10.2 %), micropapillary (6.8 %), and solid (33.5 %). A total of 27.0 % of patients developed BM, 32.9 % died without brain affection, and 40.0 % did not progress. The predominantly solid subtype showed the greatest probability of all subtypes for developing BM [HR 4.0; 95 % CI (1.80-8.91), p = 0.0006], followed by micropapillary [HR1.11; 95 % CI (0.36-3.39), p = 0.85). The solid subtype, moderately differentiated tumors, age, and ECOG PS (>2) were associated with increased hazards in the multivariate analysis. CONCLUSION According to the IASLC/ATS/ERS classification, the predominantly solid pattern was significantly associated with an increased risk of developing BM in patients with locally advanced and metastatic LADC. Its prognostic value might help explore novel clinical approaches, modify monitoring for earlier detection, prevent complications, and reduce morbidity.

Abstract
PURPOSE This study aimed to compare erlotinib (E) and etoposide/cisplatin (EP) with concurrent radiation therapy (RT) for patients with stage IIIA/B unresectable advanced non-small cell lung cancer with activating epidermal growth factor receptor mutation (EGFRm+). METHODS AND PATIENTS This was a multicenter, randomized, open-label, phase 2 trial conducted across 19 institutions in China (December 2012 to January 2016). Enrolled patients were randomized (1:1) to E + RT (oral erlotinib 150 mg/d for 2 years or until disease progression or intolerable toxicity and RT 200 cGy/d, 5 d/wk for 6 weeks from the first day of erlotinib) or EP + RT (etoposide 50 mg/m2 intravenously on days 1-5 and 29-33; cisplatin 50 mg/m2 intravenously on days 1, 8, 29 and 36; and RT as for E + RT). The primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate and safety. RESULTS Two hundred fifty-two patients were screened, and 20 patients with EGFRm+ in each group received the allocated E + RT or EP + RT treatment. Patient characteristics were well balanced between groups. Compared with EP + RT, median PFS with E + RT was significantly longer (24.5 vs 9.0 months [hazard ratio, 0.104; 95% confidence interval, 0.028-0.389; P < .001]). Objective response rate in the E + RT and EP + RT groups was 70% and 61.9%, respectively (P = .744). The incidence of adverse events (any grade) was similar between E + RT and EP + RT groups (88.9% and 84.2%). CONCLUSIONS The primary endpoint of PFS was met, and the data showed that E + RT might provide PFS improvement compared with EP + RT, with similar tolerability. However, definitive statements regarding the efficacy of concurrent E + RT in patients with unresectable stage III non-small cell lung cancer with activating EGFRm+ cannot be made, and slow patient accrual will likely make it infeasible to conduct a phase 3 study.

Risk factors for neurocognitive decline in lung cancer patients treated with prophylactic cranial irradiation: A systematic review. Cancer Treat Rev 2020; 88:102025.

Abstract
BACKGROUND Prophylactic cranial irradiation (PCI) reduces brain metastasis incidence in lung cancer, however with risk of neurocognitive decline. Nevertheless, risk factors for neurocognitive decline after PCI remain unclear. METHODS We systematically reviewed the PubMed database according to the PRISMA guideline. Inclusion criteria were: randomized clinical trials (RCTs) and observational/single arm trials evaluating PCI, including ≥20 patients, reporting neurocognitive test results for lung cancer. Primary aim: evaluate risk factors associated with neurocognitive decline after PCI. RESULTS Twenty records were eligible (8 different RCTs, 8 observational studies), including 3553 patients in total (858 NSCLC, 2695 SCLC) of which 73.6% received PCI. Incidence of mild/moderate cognitive decline after PCI varied from 8 to 89% (grading not always provided); for those without PCI, this was 3.4-42%. Interestingly, 23-95% had baseline cognitive impairment. Risk factors were often not reported. In one trial, both age (>60 years) and higher PCI dose (36 Gy) including twice-daily PCI were associated with a higher risk of cognitive decline. In one trial, white matter abnormalities were more frequent in the concurrent or sandwiched PCI arm, but without significant neuropsychological differences. One trial identified hippocampal sparing PCI to limit the neurocognitive toxicities of PCI and another reported an association between hippocampal dose volume effects and memory decline. As neurocognition was a secondary endpoint in most RCTs, and was assessed by various instruments with often poor/moderate compliance, high-quality data is lacking. CONCLUSIONS Age, PCI dose, regimen and timing might be associated with cognitive impairment after PCI in lung cancer patients, but high-quality data is lacking. Future PCI trials should collect and evaluate possible risk factors systematically.

Abstract
Background: The purpose of this study was to reevaluate the efficacy of prophylactic cranial irradiation (PCI) in non-small cell lung cancer (NSCLC) with the most recent published data and to identify subgroups who may be more likely to gain benefit from PCI. Methods: We searched PubMed, Embase, and Cochrane databases for randomized trials comparing PCI with non-PCI in NSCLC patients. We pooled the data of randomized controlled trials and compared brain metastasis (BM) and overall survival (OS) between PCI group and non-PCI group. Results: Seven studies including 1,462 patients were eligible for the current meta-analysis. Compared to non-PCI group, PCI group achieved decreased BM (RR = 0.37, 95% CI: 0.26–0.52) but similar OS (HR = 1.01, 95% CI: 0.87–1.22). In subgroup analyses of BM, PCI decreased BM for subgroups by pathology (squamous cell carcinoma or non-squamous cell carcinoma) and local treatment modality (surgery or no surgery). However, PCI failed to reduce BM for patients with poor performance status (WHO 2–3). The incidence of PCI related toxicities was low and PCI was well-tolerated by the majority of NSCLC. Low grade neurocognitive function (NCF) decline was reported in NAVLT study and greater deterioration in immediate and delayed recall was reported in RTOG 0214. No significant difference in quality of life (QOL) after PCI was reported. Conclusion: PCI reduces the incidence of BM except for patients with poor performance status. However, PCI fails to prolong OS significantly for NSCLC. An individual patient data meta-analysis may identify patients that could achieve OS prolongation with PCI.

EGFR mutant locally advanced non-small cell lung cancer is at increased risk of brain metastasis. Clin Transl Radiat Oncol 2019; 18:32-38.

Abstract
Locally advanced EGFR+ NSCLC patients have a high likelihood of brain metastasis. The high likelihood of EGFR+ brain metastasis is independent of survival duration. Surveillance MRI may allow early identification and treatment of brain metastasis.
Background and purpose Small studies of primarily metastatic non-small cell lung cancer (NSCLC) have suggested an association between EGFR mutation (EGFR+) and likelihood of brain metastasis. However, these studies are confounded by follow-up time bias. We performed a competing risk analysis of brain metastasis in a more uniform locally advanced NSCLC (LA-NSCLC) cohort with known tumor genotype. Materials and methods Between 2002 and 2014, 255 patients with LA-NSCLC underwent tumor genotyping for EGFR, ALK and/or KRAS (180 patients had follow-up brain imaging). Cumulative incidence and Fine-Gray regression were performed on clinical variables including genotype and risk of brain metastasis, with death as a competing event. Results The proportion of tumors with aberrations in EGFR, ALK and KRAS were 17%, 4% and 28%, respectively. The median follow-up was 68 months. On multivariate analysis, EGFR+ was significantly associated with risk of brain metastasis in the full patient cohort (HR 2.04, 95% CI 1.22–3.39, p = 0.006) as well as in the subset of patients with brain follow-up imaging (HR 1.91. 95% CI 1.17–3.13, p = 0.01). This translated to a higher cumulative incidence of brain metastasis in EGFR+ patients at 3 and 5 years (33.3% vs. 23.2 and 43.8% vs. 24.2%, p = 0.006). Conclusion Patients with EGFR+ LA-NSCLC have a significantly higher likelihood of developing brain metastasis after standard combined modality therapy, independent of their longer overall survival. This high-risk genotypic subgroup may benefit from routine surveillance with brain MRI to allow early salvage with targeted systemic- and/or radiation-therapies.

Abstract
Background Combined small cell lung cancer (C-SCLC) is defined as small cell lung cancer (SCLC) combined with any of non-small cell lung cancer (NSCLC) histological types, such as large cell carcinoma, squamous cell carcinoma, or adenocarcinoma. Since C-SCLC is an increasingly recognized subtype of small cell carcinoma, we conducted a retrospective study in our institution to explore the value of prophylactic cranial irradiation (PCI) in patients with C-SCLC treated by surgery. Methods Between 2005 and 2014, the records of all consecutive patients with pathologically diagnosed C-SCLC after surgery in our institution were reviewed. Overall survival (OS), disease-free survival (DFS), and brain metastasis free survival (BMFS) were estimated by Kaplan-Meier method. Survival differences were evaluated by log-rank test, while multivariate analysis was performed by a Cox proportional hazards model. Results Of the total 91 patients included in this analysis, 11 patients (12.1%) were in PCI group and 80 (87.9%) in non-PCI group. The 5-year cumulative incidence of brain metastasis in the whole group was 22.2% (26.3% in non-PCI group vs. 0% in PCI group), and 5-year OS rate was 44.1%. Patients treated with PCI had significantly longer OS (P=0.011) and DFS (P=0.013), also had the trend to live a longer BMFS with marginal significance (P=0.092) than non-PCI-treated patients. The multivariate analysis showed that PCI [hazard ratio (HR) =0.102, P=0.024] was one of independent prognostic factors of the OS in surgery-treated C-SCLC patients. Conclusions C-SCLC patients have a relative high risk of developing brain metastases based on our study. These data showed that PCI could improve OS and DFS, as well as tend to decrease brain metastases in surgically resected C-SCLC. However, whether PCI could be part of comprehensive treatment modalities in C-SCLC should be assessed in prospective studies.
