Immunotherapy has been demonstrably effective against various cancers, particularly those in the hematopoietic system and those with a high tumor-specific antigenic burden. Unfortunately, the development of immunotherapeutic strategies has proven more challenging against central nervous system (CNS) malignancies due to several unique characteristics of brain tumors that pose extraordinary barriers. To date, there is a lack of phase III trials demonstrating improved progression-free survival (PFS) and/or overall survival (OS) using immunotherapies in brain cancers. However, a better mechanistic understanding of current resistance to immunotherapies along with data from novel innovative techniques to overcome these barriers has been encouraging. This chapter gives an overview of current immunotherapies in the development of brain cancers. We will evaluate the present studies available in the clinical setting and any of their potential findings. The chapter will also discuss pertinent preclinical strategies whose translation for human use would potentially prove efficacious or provide invaluable scientific discovery.

49 Background: S-1 is the gold standard for first line therapy of advanced gastric cancer in Asia. There have been multiple meta-analyses published researching and comparing the efficacy and safety of S-1 monotherapy versus combination1,2. However there has been no analysis using actual trial data. Methods: Actual data from three randomized Phase III trials were combined to compare the efficacy of S-1 Monotherapy and S-1 combination therapy. The START trial, comparing S-1 and combination S-1 with docetaxel, SPIRITS, comparing S-1 and combination S-1 with cisplatin and TOP-002, comparing S-1 and S-1 combination with irinotecan, were merged and combined. For this analysis, the three S-1 arms were combined (n = 642) and the different S-1 combination therapy were combined (n = 617) creating two new treatment arms. The primary efficacy outcome of overall survival, progression free survival and subset analysis of overall survival stratified by baseline characteristics were performed. Results: A total of 1248 patients, including 210 Korean patients from the START were used in the analysis. The median overall survival days for S-1 combination and monotherapy was 382 [209, 648] and 321 [177, 597] and median progression free survival days for S-1 combination and monotherapy was 153 [81, 267] and 122 [61, 204]. Both overall survival (p = 0.0088 HR = 0.85 (0.76,0.96)) and progression free survival ( p = < 0.001 HR = 0.75 (0.67,0.85)) was significantly longer in the combination therapy arm compared to the monotherapy arm. Conclusions:Although there are limitations, the analysis re-confirms that S-1 combination therapy shows to be more efficacious compared to S-1 monotherapy for advanced gastric cancer patients. It must be noted that heterogeneity of the S-1 arm was not carefully considered when combining the S-1 data for the trials. In addition, the results are limited to the Asian (Japanese and Korean) population.

: We conducted a pooled analysis of two phase III trials, RV-MM-EMN-441 and EMN01, to compare maintenance with lenalidomide-prednisone vs. lenalidomide in newly diagnosed transplant-eligible and -ineligible myeloma patients. Primary endpoints were progression-free survival, progression-free survival 2 and overall survival with both regimens. A secondary aim was to evaluate the impact of duration of maintenance on overall survival and on outcome after relapse. A total of 625 patients (lenalidomide-prednisone arm, n = 315; lenalidomide arm, n = 310) were analyzed. The median follow-up was 58 months. Median progression-free survival (25 vs. 19 months; p = 0.08), progression-free survival 2 (56 vs. 49 months; p = 0.9) and overall survival (73 months vs. NR; p = 0.08) were not significantly different between the two arms. Toxicity profiles of lenalidomide-prednisone and lenalidomide were similar, with the exception of neutropenia that was higher in the lenalidomide arm (grade ≥ 3: 9% vs. 19%, p < 0.001), without an increase in the rate of infections. Overall survival (median NR vs. 49 months, p < 0.001), progression-free survival from relapse (median 35 vs. 24 months, p = 0.004) and overall survival from relapse (median not reached vs. 41 months, p = 0.002) were significantly longer in patients continuing maintenance for ≥2 years. We showed that the addition of prednisone at 25 or 50 mg every other day (eod) to lenalidomide maintenance did not induce any significant advantage.

Abstract Introduction Gynecologic malignancies are an increasingly common proportion of central nervous system metastatic disease. As genetic sequencing technology improves and becomes more accessible, mutations associated with CNS metastasis are easier to elucidate. The aims of this case series and systematic literature review are to describe the patient population with CNS metastatic disease from a gynecologic primary, and to investigate why the proportion of CNS metastasis from gynecologic malignancies is increasing. Ultimately, we hope to improve understanding of this subset of metastatic CNS malignancies and improve management strategies. Methods A literature review of articles describing patients from 1990–2020 who were diagnosed with CNS metastasis from a known gynecologic primary malignancy was performed. Demographics, cancer type, mutation characteristics, management for metastatic disease, progression free survival, number of CNS metastases, and location of metastatic disease were assessed. Inclusion criteria were age&gt;18 years, diagnosis of primary ovarian, uterine, or cervical cancer with confirmed metastatic disease to the CNS, including brain parenchyma, leptomeninges, or intradural spinal cord or dural metastases. Exclusion criteria included pediatric population and bony metastases (e.g., bony spine metastases without evidence of meningeal/parenchymal invasion). Results Our review showed that patients with gynecological metastasis to the CNS generally have worse outcomes regarding overall survival, progression free survival, and quality of life than patients without CNS metastasis. Discussion Our results infer that the reported increase in incidence of CNS metastasis from gynecologic malignancies is a reflection of improvement of detection given advances in technology, improved patient follow up, and increased overall survival of patients with gynecologic malignancies. Further characterization of mutations from gynecologic malignancies associated with brain metastasis could result in development of more treatment options for patients in the future and help determine factors that contribute to developing metastasis to the CNS of various degrees, thus, potentially inform treatment strategies.

Purpose Chemoradiation with cisplatin 100 mg/m2 given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m2 given once a week compared with cisplatin 100 mg/m2 given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC. The primary end point was locoregional control (LRC); secondary end points included toxicity, compliance, response, progression-free survival, and overall survival. Results Between 2013 and 2017, we randomly assigned 300 patients, 150 to each arm. Two hundred seventy-nine patients (93%) received chemoradiotherapy in the adjuvant setting. At a median follow-up of 22 months, the estimated cumulative 2-year LRC rate was 58.5% in the once-a-week arm and 73.1% in the once-every-3-weeks arm, leading to an absolute difference of 14.6% (95% CI, 5.7% to 23.5%); P = .014; hazard ratio (HR), 1.76 (95% CI, 1.11 to 2.79). Acute toxicities of grade 3 or higher occurred in 71.6% of patients in the once-a-week arm and in 84.6% of patients in the once-every-3-weeks arm ( P = .006). Estimated median progression-free survival in the once-a-week arm was 17.7 months (95% CI, 0.42 to 35.05 months) and in the once-every-3-weeks arm, 28.6 months (95% CI, 15.90 to 41.30 months); HR, 1.24 (95% CI, 0.89 to 1.73); P = .21. Estimated median overall survival in the once-a-week arm was 39.5 months and was not reached in the once-every-3-weeks arm (HR, 1.14 [95% CI, 0.79 to 1.65]; P = .48). Conclusion Once-every-3-weeks cisplatin at 100 mg/m2 resulted in superior LRC, albeit with more toxicity, than did once-a-week cisplatin at 30 mg/m2, and should remain the preferred chemoradiotherapy regimen for LAHNSCC in the adjuvant setting.

Abstract BACKGROUND No standard of care has been established for patients with progressive glioblastoma (rGBM). Previous studies suggested that bevacizumab (BEV) is safe and produces responses that result in a decreased use of glucocorticoids and increased progression-free survival (PFS) with an unclear effect on overall survival (OS). Crossover to BEV in the control arm is the possible reason why the advantage of BEV has not been proven in Phase III trials. We retrospectively analyzed own results of BEV treatment in rGBM. MATERIAL AND METHODS 81 patients progressed after radiotherapy plus concomitant and maintenance temozolomide (TMZ) and undergo BEV as monotherapy (BevMo, 11 patients) or in combinations (Irinotecan (BevI) - 53, lomustine (BevL)- 11, TMZ (BevT) - 6. Median age 54 years. Among them 33 patients were re-irradiated: 11 - radiosurgery (RS), 20 fractionated irradiation (RT), 2 - RS+RT. 33 patients continued BEV after progression with changing or adding cytostatic. PFS was calculated from the date of verification, PFS1 - from the date of 1-st progression, PFS2 - from the date of 2-nd progression. RESULTS Median PFS was 9.0 ([CI] 7.0–10.9) months. Median PFS1 was 10.5 ([CI] 8.1–12.9) months. In the BevMo, BevI, BevL, BevT group PFS1 was 15.7, 10.1, 10.5, 13.2 months, respectively, p=0.7. Objective response (OR) was reached in 34%, stable disease (SD) in 28%, progression (PD) in 37% patients. 16 patients stopped BEV without progression (4-patient`s decision, 7- doctor`s decision, 2 - adverse event, 3 - concomitant disease). Median time of BEV treatment was 11.6 months. Median BEV-free interval till progression was 3.7 months. 33 patients continued or restarted BEV after progression. Median PFS2 was 8.0 ([CI] 4.9–11.1) months. The median OS from the date of 1-st progression was 23.5 months ([CI] 18.7–27.4). In groups with RT, RS, RS+RT and no re-irradiarion OS was 24.6 ([CI] 17.6–31.5), 35.4 ([CI] 35.0–35.8), 17.8, 20.6 ([CI] 15.2–26.0), respectively, p=0.2. CONCLUSION OS in our group is outrageously high. Maintaining BEV after progression was effective. In our group BEV discontinuation led to rapid progression. The resumption of Bev with progression was effective, which indicates the advisability of its continuous application.
