ImportanceGlioblastoma is the most lethal primary brain cancer. Clinical outcomes for glioblastoma remain poor, and new treatments are needed.ObjectiveTo investigate whether adding autologous tumor lysate-loaded dendritic cell vaccine (DCVax-L) to standard of care (SOC) extends survival among patients with glioblastoma.Design, setting, and participantsThis phase 3, prospective, externally controlled nonrandomized trial compared overall survival (OS) in patients with newly diagnosed glioblastoma (nGBM) and recurrent glioblastoma (rGBM) treated with DCVax-L plus SOC vs contemporaneous matched external control patients treated with SOC. This international, multicenter trial was conducted at 94 sites in 4 countries from August 2007 to November 2015. Data analysis was conducted from October 2020 to September 2021.InterventionsThe active treatment was DCVax-L plus SOC temozolomide. The nGBM external control patients received SOC temozolomide and placebo; the rGBM external controls received approved rGBM therapies.Main outcomes and measuresThe primary and secondary end points compared overall survival (OS) in nGBM and rGBM, respectively, with contemporaneous matched external control populations from the control groups of other formal randomized clinical trials.ResultsA total of 331 patients were enrolled in the trial, with 232 randomized to the DCVax-L group and 99 to the placebo group. Median OS (mOS) for the 232 patients with nGBM receiving DCVax-L was 19.3 (95% CI, 17.5-21.3) months from randomization (22.4 months from surgery) vs 16.5 (95% CI, 16.0-17.5) months from randomization in control patients (HR = 0.80; 98% CI, 0.00-0.94; P = .002). Survival at 48 months from randomization was 15.7% vs 9.9%, and at 60 months, it was 13.0% vs 5.7%. For 64 patients with rGBM receiving DCVax-L, mOS was 13.2 (95% CI, 9.7-16.8) months from relapse vs 7.8 (95% CI, 7.2-8.2) months among control patients (HR, 0.58; 98% CI, 0.00-0.76; P

Objective There is a paucity of data on comparative outcomes for open versus endoscopic surgery for patients with malignant sinonasal pathology. Most of the available studies are limited by a sample size <100 patients. Design This is a retrospective cohort study. Setting The findings of this study come from a single-institution tertiary care center from 2008 to 2019. Participants In total, 199 patients who underwent surgery for malignant sinonasal disease participated in this study. Main Outcome Measures The main outcome measures were perioperative complications and reoperation. Results Patients in our sample had a mean age of 59.7 years (SD, 20.4). In total, 62% were male and 72% were white. An endoscopic-only approach was used in 41% of patients and an open or combined approach in 59% of patients. Squamous cell carcinoma was the most common pathology (43.0%), followed by sarcoma (9.5%), skin cancer (6.5%), sinonasal undifferentiated carcinoma (6.5%), and adenocarcinoma (5.5%). The all-cause complication rate was 14.6%. Patients with an open resection had a higher rate of intraoperative complications (5.9 vs. 0%; p = 0.043), postoperative complications (19.5 vs. 3.7%; p = 0.001), and all-cause complications (21.0 vs. 3.7%; p < 0.001). The likelihood of early reoperation (<6 months) or late reoperation (>6 months) did not significantly differ by surgical approach (p = 1.000 and 0.741, respectively). Conclusion The endoscopic approach for resection of malignant sinonasal disease is viable for select patients and may be associated with a favorable complication rate compared with the open approach.
