The Relationship

Abstract Several studies have been conducted to determine the relationship between post-treatment total lymphocyte count (TLC) and overall survival (OS) in patients with malignant tumors including glioblastomas (GBMs). In this retrospective study, whether patients with newly diagnosed GBM experience significant lymphopenia after concomitant chemoradiation (CCRT) was evaluated, and whether TLC after this treatment is associated with OS in the treated population was examined. Using electronic medical records, all patients newly diagnosed with GBM between 2008 and 2016 at Seoul St. Mary’s Hospital were retrospectively examined. The eligible criteria included the following: 1) craniotomy with surgical resection or biopsy, 2) completion of CCRT, 3) accessible baseline and/or follow-up complete blood count (CBC). Median TLC significantly decreased after completion of CCRT, compared to TLC at baseline (1,742 versus 1,319 cells/mm3, P-value < 0.001). Patients with TLC < 1,200 cells/mm3 at 4 weeks after the completion of CCRT showed shorter survival than those with TLC ≥ 1,200 cells/mm3 with median OS of 14.5 versus 21.0 months (P-value = 0.017). Also, in multivariate analysis for OS, TLC < 1,200 cells/mm3 at 4 weeks after the completion of CCRT (HR 1.97, 95% CI 1.61 – 2.25, P-value = 0.004) were significantly associated with shorter survival. The results from the present study indicate that treatment-related total lymphocyte counts after CCRT is associated with worse survival in patients with newly diagnosed GBM.

2017 Background: Prognosis of glioblastoma (GBM) is very poor. Standard treatment includes surgical resection (SR), radiation (RT), concomitant and adjuvant chemotherapy with temozolomide (TMZ). Our objective is to assess the treatment efficacy, safety and survival in patients with newly-diagnosed GBM treated with RT, TMZ, and bevacizumab in the upfront management. Methods: From 2006–2008, 51 eligible patients (age >18, KPS >70) with newly-diagnosed GBM divided into two groups. Group A (n = 20) was treated with RT (60Gy) and concomitant TMZ (75mg/m2 daily for 42 days) with bevacizumab (10mg/kg every 2 weeks), 29 days following surgery, followed by up to six cycles of adjuvant TMZ (150mg/m2,daily x 7d, q28 with bevacizumab at 10mg/kg days 8 and 22 of each 28 day cycle. Group B (n = 31) received similar treatment without bevacizumab. Both groups were followed up until tumor progression (PFS). Recurrence was defined according to MacDonald Criteria. The end points were PFS, overall survival (OS) and toxicity. Results: Median bevacizumab infusions were 12 (4–32). Median follow-up was14 months for both groups. 6 months PFS survival in Group A was 77.5% and in Group B was 51.6%. Median PFS in Group A was 17 months compared to 7 months in Group B (p < 0.0001, HR = 0.26). Median OS has not been reached in Group A and was 17 months in Group B. One and 2 year OS were 83% and 57% in Group A compared to 72% and 6.5% in Group B (p = 0.02) ). Post-RT and temodar toxicities include thrombocytopenia (1 patient; Gr 3 and fatigue (3 patient;1 Gr 3), bevacizumab related toxicities with RT include leg ulcer with cellulites (1 patient; Gr 3) and pulmonary embolism with thrombocytopenia (1 patient; Gr 4), hypertension (2 patients; Gr 1), and asymptomatic blood products on MRI (2 patients). Conclusions: Bevacizumab has demonstrated efficacy, acceptable toxicity, improved PFS and OS in the upfront management of GBM. No significant financial relationships to disclose.

Abstract BACKGROUND RRx-001 is an aerospace-derived radiochemosensitizer with minimal toxicity. The purpose of this trial was to establish the safety of RRx-001 plus radiotherapy and temozolomide and to look for signals of enhanced anti-tumor activity in patients with newly diagnosed glioblastoma. METHODS In this non-randomized trial called G-FORCE-1 (NCT02871843), 18 newly diagnosed, histologically verified glioblastoma patients were enrolled. The treatment plan included 6 weeks of temozolomide and radiotherapy with RRx-001 followed by maintenance temozolomide with or without RRx-001. Four cohorts of 3 patients received intravenous RRx-001 at doses of 0.5,1,2, or 4 mg/week during radiotherapy only. An additional two cohorts of 3 patients received 4 mg/week of RRx-001 during radiotherapy and 0.5 mg/week of RRx-001 during temozolomide maintenance. RESULTS There were no grade 3 or 4 dose-limiting toxicity events (DLT) that appeared related to RRx-001 for the dose range of 0.5 to 4 mg/week. A maximum tolerated dose was not defined. The main adverse event related to RRx-001 was injection-site reaction. The overall response rate was 16.7% (3 PR out of 18) pending confirmation since pseudoprogression was prevalent, and the disease control rate was 61.1% (3 PR, 8 SD out of 18). The median time to tumor progression (95% confidence interval lower limit of 9.2 months to NR) and the median overall survival time (95% confidence interval lower limit of 12.9 months to NR) have not been reached after a median follow-up time of 10.3 months (range: 2.7 to 25 months.). CONCLUSION RRx-001 was well tolerated with concurrent temozolomide and radiotherapy and with temozolomide maintenance in 18 newly diagnosed glioblastoma patients. The primary objective to determine the MTD of RRx-001 was not met, since no DLTs occurred. The median time to progression and overall survival time have not been met after a median follow up time of 10.3 months.

Abstract Background The neutrophil–lymphocyte ratio (NLR) is considered an independent predictor of mortality and myocardial infarction (MI) in stable coronary artery disease (SCAD). Also NLR have prognostic value in patients with acute coronary syndromes (ACSs). However the diagnostic power of NLR in patients suspected of ACS is still under study Objective is to determine the ability of neutrophil-lymphocyte ratio to predict troponin elevation in patients presenting to emergency department with acute coronary syndrome Material and Methods From June 2018 to March 2019, 100 patients were enrolled who presented to the ER with NST-ACS. Patients were divided into 2 groups based upon the troponin positivity in the 12- to 24-hour follow-up. Baseline Complete blood count with calculation of NLR is done Results The study population was divided into 2 groups: troponin- negative group (n = 50) and troponin-positive group (n = 50). Mean age was 55.8 ± 11.3. 77% of the patients were male. No significance difference in the level of hemoglobin, WBCs and platelets between the 2 groups. The neutrophil count was significantly higher in the troponin-positive group (p &lt; 0.001). The median admission. NLR was significantly higher in the troponin-positive group (2 vs. 3.9, P &lt; 0.001). A cutoff point of 3.4 for NLR measured on admission had 84% sensitivity and 84% specificity in predicting follow-up troponin positivity. A highly significant correlation was found between NLR and level of troponin change (p value &lt;0.01) Conclusion NLR can be used as a diagnostic tool in the differentiation of patients with acute coronary syndrome. NLR is a non-expensive, simple and available parameter that can be used in diagnosis of NSTEMI.

Background Myeloma causes profound immunodeficiency and recurrent serious infections. There are approximately 5500 new UK cases of myeloma per annum, and one-quarter of patients will have a serious infection within 3 months of diagnosis. Newly diagnosed patients may benefit from antibiotic prophylaxis to prevent infection. However, the use of prophylaxis has not been established in myeloma and may be associated with health-care-associated infections (HCAIs), such as Clostridium difficile. There is a need to assess the benefits and cost-effectiveness of the use of antibacterial prophylaxis against any risks in a double-blind, placebo-controlled, randomised clinical trial. Objectives To assess the risks, benefits and cost-effectiveness of prophylactic levofloxacin in newly diagnosed symptomatic myeloma patients. Design Multicentre, randomised, double-blind, placebo-controlled trial. A central telephone randomisation service used a minimisation computer algorithm to allocate treatments in a 1 : 1 ratio. Setting A total of 93 NHS hospitals throughout England, Northern Ireland and Wales. Participants A total of 977 patients with newly diagnosed symptomatic myeloma. Intervention Patients were randomised to receive levofloxacin or placebo tablets for 12 weeks at the start of antimyeloma treatment. Treatment allocation was blinded and balanced by centre, estimated glomerular filtration rate and intention to give high-dose chemotherapy with autologous stem cell transplantation. Follow-up was at 4-week intervals up to 16 weeks, with a further follow-up at 1 year. Main outcome measures The primary outcome was to assess the number of febrile episodes (or deaths) in the first 12 weeks from randomisation. Secondary outcomes included number of deaths and infection-related deaths, days in hospital, carriage and invasive infections, response to antimyeloma treatment and its relation to infection, quality of life and overall survival within the first 12 weeks and beyond. Results In total, 977 patients were randomised (levofloxacin, n = 489; placebo, n = 488). A total of 134 (27%) events (febrile episodes, n = 119; deaths, n = 15) occurred in the placebo arm and 95 (19%) events (febrile episodes, n = 91; deaths, n = 4) occurred in the levofloxacin arm; the hazard ratio for time to first event (febrile episode or death) within the first 12 weeks was 0.66 (95% confidence interval 0.51 to 0.86; p = 0.002). Levofloxacin also reduced other infections (144 infections from 116 patients) compared with placebo (179 infections from 133 patients; p-trend of 0.06). There was no difference in new acquisitions of C. difficile, methicillin-resistant Staphylococcus aureus and extended-spectrum beta-lactamase Gram-negative organisms when assessed up to 16 weeks. Levofloxacin produced slightly higher quality-adjusted life-year gains over 16 weeks, but had associated higher costs for health resource use. With a median follow-up of 52 weeks, there was no significant difference in overall survival (p = 0.94). Limitations Short duration of prophylactic antibiotics and cost-effectiveness. Conclusions During the 12 weeks from new diagnosis, the addition of prophylactic levofloxacin to active myeloma treatment significantly reduced febrile episodes and deaths without increasing HCAIs or carriage. Future work should aim to establish the optimal duration of antibiotic prophylaxis and should involve the laboratory investigation of immunity, inflammation and disease activity on stored samples funded by the TEAMM (Tackling Early Morbidity and Mortality in Myeloma) National Institute for Health Research Efficacy and Mechanism Evaluation grant (reference number 14/24/04).

Abstract In newly diagnosed glioblastoma (GBM), Temozolomide (TMZ) during and after radiation therapy has become standard treatment. This study describes the long-term use and follow-up results of this therapy for GBM. From 2004 to 2013 in a single institute, 112 Korean patients with newly diagnosed GBM were analyzed retrospectively. The Kaplan-Meier method, the two-sided log-rank test and Cox’s regression analysis was used to determine survival and its affecting factors. The toxicities of TMZ were evaluated using CTCAE v5.0. During the median follow-up period of 18.8 months, median PFS and OS were 9.2 and 20.3 months, respectively. This better survival outcome than the Stupp’s original study might be probably a large treatment effect of a single institution, ethnicity, and associated genetic factors. The TMZ during radiation therapy was completed in 108 patients (96.4%) and TMZ after radiation therapy in 59 patients (52.7%). Eight patients presented with grade 3 or 4 hematologic toxic effects during the protocol. Sixty-six patients (58.9%) received salvage treatment because of the poor response to adjuvant treatment or progression of the disease who achieved completion of adjuvant treatment was shown significantly longer median OS (p= 0.007) and PFS (p< 0.001). Age (< 60 years), preoperative KPS score (≥ 90), the extent of resection (≥ 78% by volumetric measurement, gross total resection), and completion of the Stupp’s protocol were significant factors affecting better survival. Between the sexes, and ages over 65 years did not show any significant difference among their groups. With marginal significances, the mutated IDH-1 and the methylated MGMT promoter showed longer median PFS(p= 0.075 and 0.777, respectively) and OS (p= 0.085 and 0.131, respectively). TMZ during and after radiation therapy might be effective and safe for newly diagnosed Korean patients with GBM. Further studies about various clinical and genetic factors affecting better survival are mandatory.

Abstract BACKGROUND High quality and value of recommended treatments is of specific importance in cancer care. ESMO, ASCO and NCCN have developed tools intended to help assessing the clinical value of cancer treatments in a standardised way, allowing for a comparative discussion. Tumor treating fields (TTFields) is a novel, device based cancer treatment, that was recently demonstrated to be effective in newly diagnosed glioblastoma (GBM). This new modality augments the treatments discussed with glioblastoma patients today. MATERIAL AND METHODS ESMO and ASCO frameworks each calculate a score for the clinical value of a cancer treatment, called Magnitude of Clinical Benefit Scale (MCBS) by ESMO and the Net Health Benefit (NHB) by ASCO. NCCN self reports “evidence blocks” which are assessed by clinician panels and were recently published for the first line treatment of newly diagnosed GBM with TTFields. We apply and compare the ESMO, ASCO and NCCN tools for TTFields treatment of newly diagnosed GBM. RESULTS The resulting ASCO NHB score for TTFields treatment of newly diagnosed GBM is 56. ESMO MCBS scores for TTFields in GBM are resulting in A/5, these being the highest achievable scores for this framework. All frameworks value the increase in overall survival by TTFields and the moderate toxicity profile. ESMO additionally values quality of life, while ASCO values palliation and treatment free intervals. NCCN’s specific focus is on the quality and consistency of the evidence. NCCN evidence blocks also contain an affordability score. CONCLUSION All three frameworks consider the clinical efficacy of a treatment and it’s toxicity profile in their clinical value assessment. Beyond that, their respective focus is on slightly different aspects and their definition of clinical value therefore varies in detail. However, all value scores suggest that TTFields treatment of newly diagnosed GBM provides a substantial clinical benefit. The high ESMO and ASCO scores are based on the significantly extended progression free and overall survival for TTFields treated patients, without adding systemic toxicities. The NCCN evidence blocks strongly support the NCCN category 1 recommendation for the use of TTFields in newly diagnosed GBM.
