PURPOSE/OBJECTIVE:Schools provide access to mental health services for traditionally underserved youth. However, there is variability in the types of school-based services students receive (e.g., school counseling, services in separate classrooms, or schools serving students with psychiatric disorders). Prior research has typically not distinguished among these different types of school-based services. The present study examines sociodemographic characteristics and disorders associated with the types of services received in schools. METHODS:Data were analyzed from a sample of adolescent-parent pairs in the U.S. National Comorbidity Survey Adolescent Supplement who received school mental health services (N = 1,204). DSM-IV diagnoses were based on the Composite International Diagnostic Interview administered to adolescents and questionnaires self-administered to parents. Adolescents (aged 13-18 years) and parents also responded to questions about lifetime school-based mental health service receipt. RESULTS:Among those receiving school-based mental health services, almost one-third (29.7%) received services in a separate classroom and almost one-fourth (22.3%) in a separate school. Increased likelihood of lifetime placement in a separate classroom or school was detected among older youth, males, blacks, Latinos, youth with learning disabilities, those whose parents had fewer years of education, and those who received community-based mental health services. Oppositional defiant disorder was associated with increased lifetime placement in a separate school. CONCLUSIONS:The results advance the evidence base by indicating that racial/ethnic minority youth and those whose parents have fewer years of education were more likely to receive school-based mental health services in separate settings. These results provide more context to studies of school-based mental health service receipt.

PURPOSE/OBJECTIVE:To evaluate the results of the randomized, double-blind, placebo-controlled phase II clinical trial of ICT-107 in patients with newly diagnosed glioblastoma. PATIENTS AND METHODS/METHODS:received radiotherapy and concurrent temozolomide. Following completion of radiotherapy, 124 patients, randomized 2:1, received ICT-107 [autologous dendritic cells (DC) pulsed with six synthetic peptide epitopes targeting GBM tumor/stem cell-associated antigens MAGE-1, HER-2, AIM-2, TRP-2, gp100, and IL13Rα2] or matching control (unpulsed DC). Patients received induction ICT-107 or control weekly × 4 followed by 12 months of adjuvant temozolomide. Maintenance vaccinations occurred at 1, 3, and 6 months and every 6 months thereafter. RESULTS:= 0.011). The frequency of HLA-A2 primary tumor antigen expression was higher than that for HLA-A1 patients, and HLA-A2 patients had higher immune response (via Elispot). HLA-A2 patients achieved a meaningful therapeutic benefit with ICT-107, in both the MGMT methylated and unmethylated prespecified subgroups, whereas only HLA-A1 methylated patients had an OS benefit. CONCLUSIONS:PFS was significantly improved in ICT-107-treated patients with maintenance of QoL. Patients in the HLA-A2 subgroup showed increased ICT-107 activity clinically and immunologically.

BACKGROUND: Clinical outcomes were associated with immune response of HLA-A2+ patients enrolled in a randomized phase 2 trial of ICT-107. METHODS: 124 patients (77 HLA-A2+), randomized 2:1, received ICT-107 (autologous DCs incubated with 6 synthetic peptide CTL epitopes targeting GBM tumor/stem cell-associated antigens MAGE-1, HER-2, AIM-2, TRP-2, gp100, and IL-13Ra2) or matching control (un-incubated DC). Immune response was determined by a functional ELISPOT assay pre and post-treatment (ICT-107 30.5% vs. 15.5% in controls). Determination of p-values and significance between dependent variables and overall survival (OS) or progression-free survival (PFS) was performed using log-rank test. Fisher's exact tests were performed for association between extended overall survival (EOS: OS > 22.2 months) and extended progression-free survival (EPFS: PFS > 16.5 months) and the same variables. RESULTS: HLA-A2+ patients showed evidence of immune response being associated with both OS and PFS. After determining HLA-A2 ELISPOT responders (responders) using a comprehensive scoring system, responders had a median OS of 23.1 months versus 13.7 for non-responders (p = 0.0673). Similarly, responders had an EOS percentage of 52% versus 29% non-responders (p = 0.0615). Further, responders had a significantly higher percentage of EPFS (41% versus 15%, p = 0.0259). When censored to 7.5 months post-treatment, immune response was found to significantly improve OS (median 17.6 months versus 13.7, p = 0.0018). Level of IL-12 production can be linked to survival. High IL-12 producers had a median OS of 20.6 compared to 15.4 for low producers (p = 0.0515). Within the treatment group, the difference was larger, with medians of 23.3 months versus 15.2 (p = 0.0654), and high producers had a significantly higher percentage of EOS (54% versus 31%, p = 0.0426) and EPFS (43% versus 19%, p = 0.0293). CONCLUSIONS: The associations identified between clinical outcomes of OS and PFS with immunologic response provide support for the efficacy of ICT-107 in HLA-A2+ patients due to a biologic T cell response

Background: Invasion is a dominant escape mechanism following angiogenic blockade in glioblastomas (GBM). Lithium has shown anti-invasive activity in glioma cells by inhibiting Glycogen Synthetase Kinase -3. This phase II study evaluated the safety and efficacy of using lithium and bevacizumab (BEV) in newly diagnosed GBM. Methods: From 2010 through 2012, 20 GBM patients with residual disease after surgery were treated with involved-field radiation therapy to 5940 cGy and concomitant temozolomide (TMZ) (75 mg/m2 daily for 42 days) along with BEV (10 mg/kg every 2 weeks), starting 29 days after surgery. This was followed by six 28-day cycles of TMZ (150 mg/m2 on days 1-7, BEV (10 mg/kg) on days 8 and 22, and lithium 300 mg BID. Lithium was increased every 7 days up to 600 mg BID with a serum lithium goal level of 0.8 to 1.2 mEq/L. Results: The median follow-up was 9.9 months (range 1.9-24.5). Fourteen patients (70.0%) received at least one dose of lithium and three patients completed the entire course of therapy. The median number of BEV infusion was 9 (range 2-19). Five patients discontinued trial due to skin sensitivity (n = 2), pulmonary embolism (n = 1), infection (n = 1), and hematological toxicity (n=1). Two patients experienced dose limiting lithium toxicity which included drowsiness (n = 1) and tremor (n = 1). No patients experienced grade 3/4 intra-cranial hemorrhage. The median progression free survival (PFS) was 9.3 months. The 12-month PFS and OS were 31.9% and 59.3% respectively. For the 14 patients who received lithium, the 12-month PFS and OS were 42.9% and 69.2% respectively. Conclusions: The strategy of targeting angiogenesis and invasion simultaneously in newly diagnosed GBM is effective and feasible

Background Whole brain radiation therapy (WBRT) reduces local recurrence in patients after surgical resection of brain metastases without improving overall survival. Involved field radiation therapy (IFRT) has been used at our center to avoid delayed neurotoxicity associated with WBRT in well-selected patients with surgically resected single brain metastases. The purpose of this study was to evaluate the long-term outcomes of these patients. Methods Thirty-three consecutive patients with single brain metastases from a known primary tumor were treated with gross total resection followed by IFRT between 2006 and 2011. The postoperative surgical bed was treated to 40.05 Gy in 15 fractions of 2.67 Gy with conformal radiation therapy. Patients received serial MRIs and neurological exams in follow-up. Surgery, WBRT, or stereotactic radiosurgery was performed as salvage treatment when necessary. Results The median follow-up was 16 months (range: 2-65 months). Local control, distant brain recurrence-free survival, and overall survival at 12 and 24 months were 90.3% and 85.8%, 60.7% and 51.4%, and 65.6% and 61.5%, respectively. Overall, 5 (15%) patients developed recurrence at the resection cavity, and 13 (39%) patients experienced recurrence at a new intracranial site. Two patients received WBRT, 8 stereotactic radiosurgery, 2 surgery, and 2 both chemotherapy and IFRT as salvage. Four patients died from CNS disease progression. Conclusion For patients with newly diagnosed single brain metastases treated with surgical resection, postoperative IFRT to the resection cavity achieves reasonable rates of local control and is an excellent alternative to WBRT.

Object The presence of angiogenesis is a hallmark of glioblastoma (GBM). Vascular endothelial growth factor (VEGF), which drives angiogenesis, provides an additional target for conventional therapy. The authors conducted a prospective clinical trial to test the effectiveness of bevacizumab, an inhibitor of VEGF, in newly diagnosed GBM. Methods From 2006 through 2010, 51 eligible patients with newly diagnosed GBM were treated with involved-field radiation therapy and concomitant temozolomide (75 mg/m(2) daily for 42 days) along with bevacizumab (10 mg/kg every 2 weeks), starting 29 days after surgery. This was followed by 6 cycles of adjuvant temozolomide therapy (150 mg/m(2) on Days 1-7 of a 28-day cycle) with bevacizumab administered at 10 mg/kg on Days 8 and 22 of each 28-day cycle. Results The 6- and 12-month progression-free survival (PFS) rates were 85.1% and 51%, respectively. The 12- and 24-month overall survival (OS) rates were 85.1% and 42.5%, respectively. Grade III/IV toxicities were noted in 10 patients (19.6%). No treatment-related deaths were observed. Asymptomatic intracranial bleeding was noted in 5 patients. Conclusions The addition of bevacizumab to conventional therapy in newly diagnosed GBM appears to improve both PFS and OS in patients with newly diagnosed GBM, with acceptable morbidity. A shift toward diffuse relapse was noted in a significant number of patients. Ongoing Phase III clinical trials will show the true benefit of this antiangiogenic approach.
