RESUMEN
OBJECTIVE: This work aimed to assess the therapeutic and economic benefits of service dogs versus emotional support dogs for veterans with posttraumatic stress disorder (PTSD). METHODS: Veterans with PTSD (N=227) participating in a multicenter trial were randomly assigned to receive a service or emotional support dog; 181 veterans received a dog and were followed up for 18 months. Primary outcomes included overall functioning (assessed with World Health Organization Disability Assessment Scale II [WHODAS 2.0]) and quality of life (Veterans RAND 12-Item Health Survey [VR-12]). Secondary outcomes included PTSD symptoms (PTSD Checklist for DSM-5), suicidal ideation, depression, sleep quality, health care costs and utilization, medication adherence, employment, and productivity. RESULTS: Participants paired with a dog had a mean±SD age of 50.6±13.6 years (range 22-79), and most were male (80%), White (66%), and non-Hispanic (91%). Adjusted linear mixed repeated-measures models indicated no difference between the two groups on WHODAS 2.0 or VR-12 scores. Participants with service dogs had a 3.7-point greater reduction in PTSD symptoms versus participants with emotional support dogs (p=0.036). No reduced health care utilization or cost was associated with receiving a service dog. Veterans with service dogs had an increase of 10 percentage points in antidepressant adherence compared with those with emotional support dogs (p<0.01). CONCLUSIONS: Both groups appeared to benefit from having a service or emotional support dog. No significant differences in improved functioning or quality of life were observed between the groups. Those in the service dog group had a greater reduction in PTSD symptoms and better antidepressant adherence, improvements that should be explored further.

Purpose: Atypical (World Health Organization [WHO] grade 2) and malignant (WHO grade 3) meningiomas have high rates of local recurrence, and questions remain about the role of adjuvant radiation therapy (RT) for patients with WHO grade 2 disease. These patients frequently require salvage therapy, and optimal management is uncertain given limited prospective data. We report on the long-term outcomes for patients with atypical and malignant meningiomas treated with surgery and/or RT at our institution. Methods and Materials: Data were collected through a retrospective chart review for all patients with WHO grade 2 or 3 meningiomas treated with surgery and/or RT at our institution between January 1992 and March 2017. Progression-free survival (PFS) and overall survival (OS) were described using the KaplanMeier estimator. The outcomes in the subgroups were compared with a log-rank test. A Cox proportional hazards model was used for the univariable and multivariable analyses of predictors of PFS. Results: A total of 66 patients were included in this analysis. The median follow-up was 12.4 years overall and 8.6 years among surviving patients. Fifty-two patients (78.8%) had WHO grade 2 meningiomas, and 14 patients (21.2%) had WHO grade 3 disease. Thirty-six patients (54.5%) were treated with surgery alone, 28 patients (42.4%) with surgery and adjuvant RT, and 2 patients (3%) with RT alone. Median PFS and OS were 3.2 years and 8.8 years, respectively. PFS was significantly improved with adjuvant RT compared with surgery alone (hazard ratio, 0.36; 95% confidence interval, 0.18-0.70). Patients with Ki-67 index >10% showed a trend toward worse PFS compared with patients with Ki-67 ≤10% (hazard ratio, 0.51; 95% confidence interval, 0.25-1.04). No significant differences in PFS or OS were observed with respect to Simpson or WHO grade. Conclusions: For patients with atypical or malignant meningiomas, adjuvant RT was associated with significantly improved PFS, and Ki-67 index >10% was associated with a trend toward worse PFS. Given the long-term survival, high recurrence rates, and efficacy of salvage therapy, patients with atypical and malignant meningiomas should be monitored systematically long after initial treatment.
RESUMEN
BACKGROUND: Spirituality can impact patients' attitudes and decisions about treatment and end-of-life care when coping with cancer. Previous studies documented health-related quality of life (HRQoL) and spiritual well-being (SWB) as positively correlated within a general cancer patient population, but little is known about their association in the primary brain tumor population. We sought to measure SWB in primary brain tumor patients and evaluate whether it was associated with HRQoL. METHODS: Six-hundred and six patients treated at The Preston Robert Tisch Brain Tumor Center at Duke between December 16, 2013 and February 28, 2014 with data in the PRoGREss registry are included in this retrospective analysis. Each patient completed the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being 12 (FACIT-Sp-12) and -Fatigue (FACIT-F), and the Functional Assessment of Cancer Therapy-General and -Brain (FACT-G and FACT-Br). RESULTS: Mean age was 49.1 years (SD = 13.5 years), male (N = 328, 54.1%), married (N = 404, 66.7%), at least college-educated (N = 381, 62.9%), and diagnosed with a high-grade glioma (N = 412, 68.0%). Multiple regression analyses were performed on both the FACT-G and the FACT-Br using the FACIT-Sp-12 sub-scales of Meaning/Peace and Faith, FACIT-F, belief in God or a higher power, prayer, gender, tumor grade, and Karnofsky Performance Status (KPS) as predictors. We found that greater SWB (measured by FACIT-Sp-12) was associated with better HRQoL (measured by FACT-G and FACT-Br; p < .0001). CONCLUSION: The association between reported SWB and reported improved HRQoL emphasizes the importance of spirituality in primary brain tumor patients, suggesting SWB must be considered in strategies to improve HRQoL.
RESUMEN
PURPOSE: Cancer survivors are often sedentary. Self-monitoring may promote physical activity through self-activation. We conducted a pilot trial to evaluate whether wearable activity tracker with personalized text message feedback would increase physical activity. METHODS: We enrolled 30 patients with solid tumor cancers into a non-randomized prospective intervention trial (NCT02627079): 15 had completed treatment in the past year and 15 under active treatment. Each participant received an activity tracker and daily text messages personalized to their activity level. We assessed patient-reported outcomes and 6-min walk (6 MW) at baseline and 3 months. RESULTS: Twenty-six participants completed the study. There was substantial variation in baseline activity. Overall, 39% of participants increased their steps taken by at least 20%, and 23% increased their 6 MW distance by 20% or more. More participants who had completed treatment strongly agreed (73%) that the intervention increased their exercise levels than those receiving active treatment (47%). At 3 months, there was a significant improvement in median Beck Depression Inventory-II and Godin Leisure Index composite scores. At 6 months, 72% still wore their activity tracker at least 4 days per week. CONCLUSION: We found that the intervention was well-accepted with a high completion rate at 3 months and continued self-use at 6 months. In this pilot study of combined activity tracker and motivational messaging, we found a signal for increased physical activity over a 3-month period. Future research is needed to study this technique for its impact on activity and other physical and psychological measures of well-being. IMPLICATION FOR CANCER SURVIVORS: Activity tracker with personalized motivational messaging may be useful in promoting physical activity in cancer survivors.

OBJECTIVES: Standard 6-week and hypofractionated 3-week courses of adjuvant radiation therapy (RT) are both options for older patients with glioblastoma (GBM), but deciding the optimal regimen can be challenging. This analysis explores clinical factors associated with selection of RT course, completion of RT, and outcomes following RT. MATERIALS AND METHODS: This IRB-approved retrospective analysis identified patients ≥70 years old with GBM who initiated adjuvant RT at our institution between 2004 and 2016. We identified factors associated with standard or hypofractionated RT using the Cochran-Armitage trend test, estimated time-to-event endpoints using the Kaplan-Meier method, and found predictors of overall survival (OS) using Cox proportional hazards models. RESULTS: Sixty-two patients with a median age of 74 (range 70-90) initiated adjuvant RT, with 43 (69%) receiving standard RT and 19 (31%) receiving hypofractionated RT. Selection of short-course RT was associated with older age (p = 0.04) and poor KPS (p = 0.03). Eight (13%) patients did not complete RT, primarily for hospice care due to worsening symptoms. After a median follow-up of 37 months, median OS was 12.3 months (95% CI 9.0-15.1). Increased age (p < 0.05), poor KPS (p < 0.0001), lack of MGMT methylation (p < 0.05), and lack of RT completion (p < 0.0001) were associated with worse OS on multivariate analysis. In this small cohort, GTV size and receipt of standard or hypofractionated RT were not associated with OS. CONCLUSIONS: In this cohort of older patients with GBM, age and KPS was associated with selection of short-course or standard RT. These regimens had similar OS, though a subset of patients experienced worsening symptoms during RT and discontinued treatment. Further investigation into predictors of RT completion and survival may help guide adjuvant therapies and supportive care for older patients.
RESUMEN
Several immunotherapy clinical trials in recurrent glioblastoma have reported long-term survival benefits in 10-20% of patients. Here we perform genomic analysis of tumor tissue from recurrent WHO grade IV glioblastoma patients acquired prior to immunotherapy intervention. We report that very low tumor mutation burden is associated with longer survival after recombinant polio virotherapy or after immune checkpoint blockade in recurrent glioblastoma patients. A relationship between tumor mutation burden and survival is not observed in cohorts of immunotherapy naïve newly diagnosed or recurrent glioblastoma patients. Transcriptomic analyses reveal an inverse relationship between tumor mutation burden and enrichment of inflammatory gene signatures in cohorts of recurrent, but not newly diagnosed glioblastoma tumors, implying that a relationship between tumor mutation burden and tumor-intrinsic inflammation evolves upon recurrence.

PURPOSE: CINV remains a distressing side effect experienced by glioma patients receiving multi-day temozolomide therapy, in spite of guideline-based antiemetic therapy with selective serotonin-receptor-antagonists. Antiemetic research with aprepitant has routinely excluded glioma patients. In this randomized open-label phase II study, use of a nonstandard 5-day regimen of aprepitant for glioma patients was investigated. METHODS: One hundred thirty-six glioma patients receiving their first cycle of adjuvant temozolomide (150-200 mg/m2/day × 5 days every 28 days) were randomized to Arm-A (ondansetron 8 mg days 1-5 with aprepitant day 1: 125 mg, days 2-5: 80 mg) or Arm-B (ondansetron). Randomization was stratified by tumor grade and number of prior chemotherapy regimens. The primary endpoint was the percentage of patients achieving complete control (CC), defined as no emetic episode or antiemetic rescue medication over the 7-day study period. Secondary endpoints included CINV efficacy in the acute phase (≤ 24 h) and delayed phase (days 2-7), as well as safety and quality of life (QoL). RESULTS: Patients were 61% male, 97% white, 48% with KPS > 90%, 60% non-smokers, mean age 54, 92% with low alcohol use, and 46% with a CINV history. The CC was 58.6% (Arm-A) and 54.5% (Arm-B). Acute-complete response (CR) rates, defined as CC on day 1 in Arm-A and -B, were 97.1% and 87.9%, respectively (p = 0.056). Treatment-related toxicities were mild or moderate in severity. CONCLUSIONS: Aprepitant plus ondansetron may increase acute-CR, may have benefit regarding CINV's effect on QoL, and is safe for 5-day temozolomide compared to ondansetron. This study provides no evidence that aprepitant increases CC rate over ondansetron alone.

BACKGROUND: Overall survival (OS) in glioblastoma (GBM) is poor at an average of 14 to 18 months, and long-term survivors (LTS) of GBM are rare. LTS of GBM, defined as surviving >5 years postdiagnosis, represent only 2% to 10% of all GBM patients. LTS of cancer are at high risk of developing second primary neoplasms. This study looks at occurrences of second primary neoplasms in LTS of GBM. METHODS: Records from adult patients newly diagnosed with GBM between January 1, 1998 and February 8, 2010, were retrospectively reviewed to identify LTS, defined as patients who survived ≥5 years. We focused on the identification of a new diagnosis of cancer occurring at least 2 years after the initial GBM diagnosis. RESULTS: We identified 155 LTS of GBM, with a median OS of 11.0 years (95% CI: 9.0 to 13.1 years) and a median follow-up of 9.6 years (95% CI: 8.7 to 10.7 years). In this cohort of patients, 13 (8.4%) LTS of GBM developed 17 secondary cancers. Eight could potentially be attributed to previous radiation and chemotherapy (skin cancer in radiation field [n = 4], leukemia [n = 2], low-grade glioma [n = 1], and sarcoma of the scalp [n = 1]). The other 9 cases included melanoma (n = 2), prostate cancer (n = 2), bladder cancer (n = 1), endometrioid adenocarcinoma (n = 1), basal cell carcinoma (n = 1), and renal cell carcinoma (n = 1). CONCLUSIONS: Although second primary cancers are rare in GBM LTS, providers should continue close monitoring with appropriate oncologic care. Moreover, this highlights the need for survivorship care of patients with GBM.
RESUMEN
BACKGROUND AND PURPOSE: Little is known about complementary and integrative health intervention usage in the primary brain tumor population. We aimed to identify the percentage of patients using these practices and explore the impact on quality of life. MATERIALS AND METHODS: Clinical records from patients seen in clinic between December 16, 2013 and February 28, 2014 were reviewed retrospectively. The questionnaires used were a modified version of the International Complementary and Alternative Medicine Questionnaire, the Functional Assessment of Cancer Therapy- Brain Cancer and the Functional Assessment of Chronic Illness Therapy- Fatigue. RESULTS: 76% of patients utilized a complementary and integrative health modality. The most frequently reported modalities used were vitamins, massage, and spiritual healing, prayer, diet and meditation. CONCLUSION: These results confirm the usage of complementary and integrative health practices within the primary brain tumor population; however, there was no evidence of association between use and quality of life.

BACKGROUND AND AIMS: This retrospective review of patients with recurrent glioblastoma treated at the Preston Robert Tisch Brain Tumor Center investigated treatment patterns, survival, and safety with bevacizumab in a real-world setting. METHODS: Adult patients with glioblastoma who initiated bevacizumab at disease progression between January 1, 2009, and May 14, 2012, were included. A Kaplan-Meier estimator was used to describe overall survival (OS), progression-free survival (PFS), and time to greater than or equal to 20% reduction in Karnofsky Performance Status (KPS). The effect of baseline demographic and clinical factors on survival was examined using a Cox proportional hazards model. Adverse event (AE) data were collected. RESULTS: Seventy-four patients, with a median age of 59 years, were included in this cohort. Between bevacizumab initiation and first failure, defined as the first disease progression after bevacizumab initiation, biweekly bevacizumab and bevacizumab/irinotecan were the most frequently prescribed regimens. Median duration of bevacizumab treatment until failure was 6.4 months (range, 0.5-58.7). Median OS and PFS from bevacizumab initiation were 11.1 months (95% confidence interval [CI], 7.3-13.4) and 6.4 months (95% CI, 3.9-8.5), respectively. Median time to greater than or equal to 20% reduction in KPS was 29.3 months (95% CI, 13.8-∞). Lack of corticosteroid usage at the start of bevacizumab therapy was associated with both longer OS and PFS, with a median OS of 13.2 months (95% CI, 8.6-16.6) in patients who did not initially require corticosteroids versus 7.2 months (95% CI, 4.8-12.5) in those who did (P = 0.0382, log-rank), while median PFS values were 8.6 months (95% CI, 4.6-9.7) and 3.7 months (95% CI, 2.7-6.6), respectively (P = 0.0243, log-rank). Treatment failure occurred in 70 patients; 47 of whom received salvage therapy, and most frequently bevacizumab/carboplatin (7/47; 14.9%). Thirteen patients (18%) experienced a grade 3 AE of special interest for bevacizumab. CONCLUSIONS: Treatment patterns and outcomes for patients with recurrent glioblastoma receiving bevacizumab in a real-world setting were comparable with those reported in prospective clinical trials.
RESUMEN
BACKGROUND: The prognosis of patients with recurrent World Health Organization (WHO) grade IV malignant glioma is dismal, and there is currently no effective therapy. We conducted a dose-finding and toxicity study in this population of patients, evaluating convection-enhanced, intratumoral delivery of the recombinant nonpathogenic polio-rhinovirus chimera (PVSRIPO). PVSRIPO recognizes the poliovirus receptor CD155, which is widely expressed in neoplastic cells of solid tumors and in major components of the tumor microenvironment. METHODS: We enrolled consecutive adult patients who had recurrent supratentorial WHO grade IV malignant glioma, confirmed on histopathological testing, with measurable disease (contrast-enhancing tumor of ≥1 cm and ≤5.5 cm in the greatest dimension). The study evaluated seven doses, ranging between 107 and 1010 50% tissue-culture infectious doses (TCID50), first in a dose-escalation phase and then in a dose-expansion phase. RESULTS: From May 2012 through May 2017, a total of 61 patients were enrolled and received a dose of PVSRIPO. Dose level -1 (5.0×107 TCID50) was identified as the phase 2 dose. One dose-limiting toxic effect was observed; a patient in whom dose level 5 (1010 TCID50) was administered had a grade 4 intracranial hemorrhage immediately after the catheter was removed. To mitigate locoregional inflammation of the infused tumor with prolonged glucocorticoid use, dose level 5 was deescalated to reach the phase 2 dose. In the dose-expansion phase, 19% of the patients had a PVSRIPO-related adverse event of grade 3 or higher. Overall survival among the patients who received PVSRIPO reached a plateau of 21% (95% confidence interval, 11 to 33) at 24 months that was sustained at 36 months. CONCLUSIONS: Intratumoral infusion of PVSRIPO in patients with recurrent WHO grade IV malignant glioma confirmed the absence of neurovirulent potential. The survival rate among patients who received PVSRIPO immunotherapy was higher at 24 and 36 months than the rate among historical controls.

LESSONS LEARNED: Due to evolving imaging criteria in brain tumors and variation in magnetic resonance imaging evaluation, it is not ideal to use response rate as a primary objective. Future studies involving antiangiogenic agents should use overall survival.Disease-expected toxicities should be considered when defining the clinical significance of an adverse event. For example, vascular thromboembolic events are common in brain tumor patients and should not be attributed to the study drug in the safety analysis. BACKGROUND: Recurrent malignant glioma (rMG) prognosis is poor, with a median patient survival of 3-11 months with bevacizumab (BEV)-containing regimens. BEV in rMG has 6-month progression free survival (PFS-6) of â¼40% and an objective response rate of 21.2%. BEV-containing regimens improve PFS-6 to 42.6%-50.3%, indicating that BEV combination therapies may be superior to single agent. Rilotumumab, a hepatocyte growth factor (HGF) antibody, inhibits angiogenesis and expression of angiogenic autocrine factors (e.g., vascular endothelial growth factor [VEGF]) by c-Met inhibition. Combination of rilotumumab with BEV to block vascular invasion and tumor proliferation may synergistically inhibit tumor growth. METHODS: Thirty-six BEV-naïve rMG subjects received rilotumumab (20 mg/kg and BEV (10 mg/kg) every 2 weeks. Endpoints included objective response rate (using Response Assessment in Neuro-Oncology [RANO] criteria), PFS-6, overall survival (OS), and toxicity. RESULTS: Median patient follow-up was 65.0 months. Objective response rate was 27.8% (95% confidence interval [CI]: 15.7%-44.1%). Median OS was 11.2 months (95% CI: 7-17.5). PFS-6 was 41.7% (95% CI: 25.6%-57.0%). Most frequent treatment-related grade ≤2 events included weight gain, fatigue, allergic rhinitis, and voice alteration; grade ≥3 events included venous thromboembolism (four patients), including one death from pulmonary embolism. CONCLUSION: Rilotumumab with BEV did not significantly improve objective response compared with BEV alone, and toxicity may preclude the use of rilotumumab in combination BEV regimens.

LESSONS LEARNED: Combination regimen with bevacizumab (BEV) and vorinostat is well tolerated in patients with recurrent glioblastoma.Treatment of recurrent glioblastoma remains challenging as this study and others attempt to improve progression-free survival and overall survival with BEV-containing regimens. BACKGROUND: Recurrent glioblastoma (GBM; World Health Organization grade 4) continues to have a very poor prognosis. Bevacizumab (BEV) has been shown to improve progression-free survival (PFS) in recurrent GBM and is approved by the U.S. Food and Drug Administration for the treatment of recurrent GBM. Combination regimens have been explored, and in this phase II nonrandomized trial, we evaluated the efficacy of BEV combined with histone deacetylase inhibitor vorinostat (VOR) in recurrent GBM. MATERIALS AND METHODS: In this phase II, single-center, nonrandomized study, subjects with recurrent GBM received BEV 10 mg/kg intravenously (IV) every 2 weeks combined with VOR 400 mg p.o. daily for 7 days on, 7 days off, in a 28-day cycle. The primary endpoint was 6-month PFS (PFS6). RESULTS: Forty patients with recurrent GBM were enrolled and evaluated. PFS6 was 30.0% (95% confidence interval [CI] 16.8%-44.4%). Median overall survival (OS) was 10.4 months (95% CI 7.6-12.8 months). Overall radiographic response rate was 22.5% based on 9 partial responses. The most common grade 2 and above treatment-related adverse events were lymphopenia (55%), leukopenia (45%), neutropenia (35%), and hypertension (33%). Grade 4 adverse events were leukopenia (3%), neutropenia (3%), sinus bradycardia (3%), and venous thromboembolism (3%). Two deaths occurred in this study, with one due to tumor progression and another possibly related as death not otherwise specified. CONCLUSION: Combination treatment of BEV and VOR was well tolerated. This combination therapy for this study population did not improve PFS6 or median OS when compared with BEV monotherapy.

BACKGROUND: The objective of this study was to evaluate the safety and feasibility of using neoadjuvant chemotherapy plus ipilimumab followed by surgery as a treatment strategy for stage II-IIIA non-small cell lung cancer. METHODS: From 2013 to 2017, postoperative data from patients who underwent surgery after neoadjuvant chemotherapy plus ipilimumab in the TOP1201 trial, an open label phase II trial (NCT01820754), were prospectively collected. The surgical outcomes from TOP1201 were compared with outcomes in a historical cohort of patients receiving standard preoperative chemotherapy followed by surgery identified from our institution's prospectively collected thoracic surgery database. RESULTS: In the TOP1201 trial, 13 patients were treated with preoperative chemotherapy and ipilimumab followed by surgery. In the historical cohort, 42 patients received preoperative chemotherapy by a platinum doublet regimen preoperative chemotherapy by a platinum doublet regimen without ipilimumab followed by lobectomy or pneumonectomy. The 30-day mortality in both groups was 0%. The most frequently occurring perioperative complications in the TOP1201 group were prolonged air leak (n = 2, 15%) and urinary tract infection (n = 2, 15%). The most common perioperative complication in the preoperative chemotherapy alone group was atrial fibrillation (n = 6, 14%). One patient (8%) had atrial fibrillation in the TOP1201 group. There was no apparent increased occurrence of adverse surgical outcomes for patients in the TOP1201 group compared with patients receiving standard of care neoadjuvant chemotherapy alone before surgery for stage II-IIIA non-small cell lung cancer. CONCLUSIONS: This report is the first to demonstrate the safety and feasibility of surgical resection after treatment with ipilimumab and chemotherapy in stage II-IIIA non-small-cell lung cancer.

Prognosis of recurrent glioblastoma (GBM) is poor with 6-month progression-free survival (PFS6) ranging from 9 to 48% depending on the treatment regimen and use of anti-angiogenic therapies. We sought to study vorinostat (VOR), a histone deacetylase inhibitor, in combination with bevacizumab (BEV) and daily metronomic temozolomide (TMZ) in a Phase I/II trial in recurrent high-grade gliomas (HGGs). This was a Phase I/II open-label, single-arm study in recurrent HGG patients. Phase I primary endpoint was to determine the maximum tolerated dose (MTD) of VOR with BEV and daily TMZ. Phase II primary endpoint was PFS6. Regimen was BEV 10 mg/kg iv every 2 weeks, TMZ 50 mg/m2 po daily, and VOR 200 or 400 mg po alternating 7 days on then 7 days off throughout a 28-day cycle. Phase I portion enrolled nine subjects with three receiving VOR 200 mg and 6 receiving VOR 400 mg. With no dose-limiting toxicities (DLTs) at 200 mg and one DLT (thrombocytopenia, Grade 3) at 400 mg, the MTD was 400 mg. Phase II portion enrolled 39 GBM subjects, and PFS6 was 53.8% (95% CI 37.2-67.9%). Of note, 14 subjects had received prior BEV and all had received prior 5-day TMZ. Combination therapy with VOR, BEV, and daily TMZ was well tolerated and safe. While PFS6 was not statistically improved beyond historical controls, it is important to note that this was a heavily pretreated GBM population and further consideration is warranted in a less pretreated group.

INTRODUCTION: Due to the neurocognitive side effects of whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) is being used with increasing frequency. The use of SRS is expanding for patients with multiple (>4) brain metastases (BM). This study summarizes our institutional experience with single-fraction, linear-accelerator-based SRS for multiple BM. METHODS AND MATERIALS: All patients who were treated between January 1, 2013, and September 30, 2015, with single-fraction SRS for ≥4 BM were included in this institutional review board-approved, retrospective, single-institution study. Patients were treated with linear accelerator-based image guided SRS. RESULTS: A total of 59 patients with ≥4 BM were treated with single-fraction SRS. The median follow-up was 15.2 months, and the median overall survival for the entire cohort was 5.8 months. The median number of treated lesions per patient was 5 (range, 4-23). Per patient, the median planning target volume (PTV) was 4.8 cc (range, 0.7-28.8 cc). The prescribed dose across all 380 BM for the 59 patients ranged from 7 to 20 Gy. The median of the mean dose to the total PTV was 19.5 Gy. Although the number of treated lesions (4-5 vs ≥6) did not influence survival, better survival was noted for a total PTV <10 cc versus ≥10 cc (7.1 vs 4.2 months, respectively; P = .0001). A mean dose of ≥19 Gy to the entire PTV was also associated with increased survival (6.6 vs 5.0 months, respectively; P = .0172). Patients receiving a dose of >12 Gy to ≥10 cc of normal brain had worse survival (5.1 vs 8.6 months, respectively; P = .0028). CONCLUSION: In single-fraction SRS for patients with multiple BM, smaller total tumor volume, higher total dose, and lower volume of normal brain receiving >12 Gy were associated with increased survival. These data suggest that using SRS for the treatment of multiple BM is efficacious and that outcomes may be affected more by total tumor volume than by the number of lesions.
RESUMEN
Purpose: To determine the immunologic effects of neoadjuvant chemotherapy plus ipilimumab in early-stage non-small cell lung cancer (NSCLC) patients.Experimental Design: This is a single-arm chemotherapy plus phased ipilimumab phase II study of 24 treatment-naïve patients with stage IB-IIIA NSCLC. Patients received neoadjuvant therapy consisting of 3 cycles of paclitaxel with either cisplatin or carboplatin and ipilimumab included in the last 2 cycles.Results: Chemotherapy alone had little effect on immune parameters in PBMCs. Profound CD28-dependent activation of both CD4 and CD8 cells was observed following ipilimumab. Significant increases in the frequencies of CD4+ cells expressing activation markers ICOS, HLA-DR, CTLA-4, and PD-1 were apparent. Likewise, increased frequencies of CD8+ cells expressing the same activation markers, with the exception of PD-1, were observed. We also examined 7 resected tumors and found higher frequencies of activated tumor-infiltrating lymphocytes than those observed in PBMCs. Surprisingly, we found 4 cases of preexisting tumor-associated antigens (TAA) responses against survivin, PRAME, or MAGE-A3 present in PBMC at baseline, but neither increased frequencies nor the appearance of newly detectable responses following ipilimumab therapy. Ipilimumab had little effect on the frequencies of circulating regulatory T cells and MDSCs.Conclusions: This study did not meet the primary endpoint of detecting an increase in blood-based TAA T-cell responses after ipilimumab. Collectively, these results highlight the immune activating properties of ipilimumab in early-stage NSCLC. The immune profiling data for ipilimumab alone can contribute to the interpretation of immunologic data from combined immune checkpoint blockade immunotherapies.

Primary brain tumor patients experience high levels of distress. The purpose of this cross-sectional, retrospective study is to evaluate the level and different sources of psychosocial distress and how these pertain to health-related quality of life (HRQoL). The Primary and Recurrent Glioma registry at Duke's The Preston Robert Tisch Brain Tumor Center was queried retrospectively for demographic and clinical information on patients seen between December 2013 and February 2014. Data also included the National Comprehensive Cancer Network's Distress Thermometer (NCCN-DT), Functional Assessment of Cancer Therapy-Brain Cancer (FACT-Br), and Functional Assessment of Chronic Illness Therapy- Fatigue (FACIT-F). 829 subjects completed questionnaires. 54% were male; 96% completed the NCCN-DT; 33.3% had a DT score ≥4 (moderate/severe distress). Women reported DT ≥ 4 more often than men (38.6 vs 29.0%; p = 0.005). Patients within 1 year of diagnosis reported DT ≥ 4 more often than those 1+ years after diagnosis (38.8 vs 30.9%; p = 0.034). 73.0% reported physical problems; the most frequent being fatigue (43.2%) and memory/concentration (40.9%). 42.0% complained of emotional problems with worry (29.4%) and nervousness (22.4%) being the most common. Patients who reported at least one practical, family, emotional or physical problem had significantly lower HRQoL scores (p < 0.001). Primary brain tumor patients experience memory dysfunction, fatigue, nervousness, worry, and financial concerns, which have a negative effect on the patient's HRQoL. By identifying and addressing these stressors, it may be possible to improve patient HRQoL.

BACKGROUND: Stereotactic radiosurgery (SRS) offers excellent local control for brain metastases (BM) with low rates of toxicity. Radiation necrosis (RN) may occur after treatment and is challenging to distinguish from local recurrence (LR). We evaluated enlarging brain lesions following SRS that were subsequently biopsied to differentiate RN versus LR. METHODS: This study reviewed patients receiving SRS for BM between 2008 and 2012 who underwent a biopsy for suspicion of RN versus LR on MRI. Data collection included demographics, radiation parameters, imaging findings, and post-biopsy pathology. Kaplan-Meier methods determined overall survival. Fisher's exact test assessed for association between lesion biopsy result and variables of interest. RESULTS: Thirty-four patients with 35 biopsied BM were included. Lesions were biopsied a median of 8.8 months after SRS. Most patients had primary lung cancer (11; 31.4%). Eleven (31.4%) biopsies were positive for LR and 24 (68.6%) showed RN only. Median overall survival was longer for patients with RN (31.0 mo) than for patients with LR (14.5 mo; P = 0.135). Time from SRS to biopsy was significantly different between RN and LR groups; 10 lesions (52.5%) biopsied ≤9 months after SRS showed LR, whereas 1 lesion (6.3%) biopsied >9 months after SRS showed LR (P = 0.004). For 16 (65.7%) lesions, management was changed or directed by the biopsy results. CONCLUSIONS: Stereotactic biopsy for accessible enlarging lesions after SRS appears diagnostically valuable in patients with few lesions and changes clinical management. RN should be suspected in patients with an enlarging lesion more than 9 months post-SRS.

PURPOSE: Given that the prognosis of recurrent malignant glioma (MG) remains poor, improving quality of life (QoL) through symptom management is important. Meta-analyses establishing antiemetic guidelines have demonstrated the superiority of palonosetron (PAL) over older 5-hydroxytryptamine 3-receptor antagonists in chemotherapy-induced nausea and vomiting (CINV) prevention, but excluded patients with gliomas. Irinotecan plus bevacizumab is a treatment frequently used in MG, but is associated with low (55%) CINV complete response (CR; no emesis or use of rescue antiemetic) with commonly prescribed ondansetron. A single-arm Phase II trial was conducted in MG patients to determine the efficacy of intravenous PAL (0.25 mg) and dexamethasone (DEX; 10 mg) received in conjunction with biweekly irinotecan-bevacizumab treatment. The primary end point was the proportion of subjects achieving acute CINV CR (no emesis or antiemetic ≤24 hours postchemotherapy). Secondary end points included delayed CINV CR (days 2-5), overall CINV CR (days 1-5), and QoL, fatigue, and toxicity. MATERIALS AND METHODS: A two-stage design of 160 patients was planned to differentiate between CINV CR of 55% and 65% after each dose of PAL-DEX. Validated surveys assessed fatigue and QoL. RESULTS: A total of 63 patients were enrolled, after which enrollment was terminated due to slow accrual; 52 patients were evaluable for the primary outcome of acute CINV CR. Following PAL-DEX dose administrations 1-3, acute CINV CR rates were 62%, 68%, and 70%; delayed CINV CR rates were 62%, 66%, and 70%, and overall CINV CR rates were 47%, 57%, and 62%, respectively. Compared to baseline, there was a clinically meaningful increase in fatigue during acute and overall phases, but not in the delayed phase. There were no grade ≥3 PAL-DEX treatment-related toxicities. CONCLUSION: Data suggest that PAL-DEX is effective in preventing CINV in MG patients, which ultimately maintains the QoL of patients with glioma.
