Abstract
INTRODUCTION Adjuvant immunotherapy (IO) following concurrent chemotherapy and photon radiation therapy confers an overall survival (OS) benefit for patients with inoperable locally advanced non-small cell lung carcinoma (LA-NSCLC); however, outcomes of adjuvant IO after concurrent chemotherapy with proton beam therapy (CPBT) are unknown. We investigated OS and toxicity after CPBT with adjuvant IO versus CPBT alone for inoperable LA-NSCLC. MATERIALS AND METHODS We analyzed 354 patients with LA-NSCLC who were prospectively treated with CPBT with or without adjuvant IO from 2009 to 2021. Optimal variable ratio propensity score matching (PSM) matched CPBT with CPBT + IO patients. Survival was estimated with the Kaplan-Meier method and compared with log-rank tests. Multivariable Cox proportional hazards regression evaluated the effect of IO on disease outcomes. RESULTS Median age was 70 years; 71 (20%) received CPBT + IO and 283 (80%) received CPBT only. After PSM, 71 CPBT patients were matched with 71 CPBT + IO patients. Three-year survival rates for CPBT + IO vs CPBT were: OS 67% vs 30% (P < 0.001) and PFS 59% vs 35% (P = 0.017). Three-year LRFS (P = 0.137) and DMFS (P = 0.086) did not differ. Receipt of adjuvant IO was a strong predictor of OS (HR 0.40, P = 0.001) and PFS (HR 0.56, P = 0.030), but not LRFS (HR 0.61, P = 0.121) or DMFS (HR 0.61, P = 0.136). There was an increased incidence of grade ≥3 esophagitis in the CPBT-only group (6% CPBT + IO vs 17% CPBT, P = 0.037). CONCLUSION This study, one of the first to investigate CPBT followed by IO for inoperable LA-NSCLC, showed that IO conferred survival benefits with no increased rates of toxicity.

Abstract
PURPOSE Use of biologic or synthetic mesh in hernia repair shifts is based on evolving evidence. Poly-4-hydroxybutyrate (P4HB) biosynthetic mesh is a potential alternative to biologic and synthetic mesh in ventral hernia repair (VHR). This meta-analysis assesses the efficacy of P4HB mesh in clean and contaminated surgical settings. METHODS Two authors searched literature on PubMed, reviewing titles and abstracts of all articles to determine inclusion eligibility. Post-operative data were compared via transformation method to convert the proportion of patients with the outcome of interest into a suitable quantity for random-effects synthesis using STATA software. RESULTS Initial search yielded 287 citations. Six studies were included and categorized on whether hernia repairs were conducted in clean (CDC class I) or contaminated cases (CDC class II-IV). The pooled proportion of surgical site infection (SSI), surgical site occurrence (SSO), hernia recurrence, total surgical complications, and reoperation were calculated in 391 clean and 81 contaminated cases. For clean vs. contaminated cases, the following pooled proportions were noted: SSI (2% (CI 0-7%) vs 9% (CI 0-025) (p = 0.03), SSO: 14% (CI 5-25%) vs 35% (CI 22-50%) (p = 0.006), hernia recurrence (8% (CI 1-19%) vs 4% (CI 0-12%) (p = 0.769); surgical complications (17% (CI 6-32%) vs 50% (CI 27-72%) (p = 0.009). Reoperation data were available in 298 clean cases across four studies: 5% (CI 0-15%). CONCLUSIONS P4HB biosynthetic mesh may be more effective than previously thought, particularly in clean wounds. P4HB may also be superior to biologic mesh when compared to clinical trial data. Further research is necessary for more direct comparison.

Abstract
The roles of preexisting auto-reactive antibodies in immune-related adverse events (irAEs) associated with immune checkpoint inhibitor therapy are not well defined. Here, we analyzed plasma samples longitudinally collected at predefined time points and at the time of irAEs from 58 patients with immunotherapy naïve metastatic non-small cell lung cancer treated on clinical protocol with ipilimumab and nivolumab. We used a proteomic microarray system capable of assaying antibody reactivity for IgG and IgM fractions against 120 antigens for systemically evaluating the correlations between auto-reactive antibodies and certain organ-specific irAEs. We found that distinct patterns of auto-reactive antibodies at baseline were associated with the subsequent development of organ-specific irAEs. Notably, ACHRG IgM was associated with pneumonitis, anti-cytokeratin 19 IgM with dermatitis, and anti-thyroglobulin IgG with hepatitis. These antibodies merit further investigation as potential biomarkers for identifying high-risk populations for irAEs and/or monitoring irAEs during immunotherapy treatment. Trial registration ClinicalTrials.gov identifier: NCT03391869.

Abstract
INTRODUCTION Immune checkpoint inhibitor (ICI) pneumonitis causes substantial morbidity and mortality. Estimates of real-world incidence and reported risk factors vary substantially. METHODS We conducted a retrospective review of 419 patients with advanced non-small cell lung cancer (NSCLC) who were treated with anti-PD-(L)1 with or without anti-CTLA-4 therapy. Clinical, imaging, and microbiological data were evaluated by multidisciplinary adjudication teams. The primary outcome of interest was grade ≥2 (CTCAEv5) pneumonitis. Clinicopathologic variables, tobacco use, cancer therapies, and preexisting lung disease were assessed for univariate effects using Cox proportional hazards models. We created multivariate Cox proportional hazards models to assess risk factors for pneumonitis and mortality. Pneumonitis, pneumonia, and progression were modeled as time-dependent variables in mortality models. RESULTS We evaluated 419 patients between 2013 and 2021. The cumulative incidence of pneumonitis was 9.5% (40/419). In a multivariate model, pneumonitis increased the risk for mortality (HR 1.6, 95% CI, 1.0-2.5), after adjustment for disease progression (HR 1.6, 95% CI, 1.4-1.8) and baseline shortness of breath (HR 1.5, 95% CI, 1.2-2.0). Incomplete resolution was more common with more severe pneumonitis. Interstitial lung disease was associated with higher risk for pneumonitis (HR 5.4, 95% CI, 1.1-26.6), particularly in never smokers (HR 26.9, 95% CI, 2.8-259.0). CONCLUSION Pneumonitis occurred at a high rate and significantly increased mortality. Interstitial lung disease, particularly in never smokers, increased the risk for pneumonitis.

Abstract
AIMS Pneumonitis is a common and potentially deadly complication of combined chemoradiation and immune checkpoint inhibition (CRT-ICI) in patients with locally advanced non-small cell lung cancer (LA-NSCLC). In this study we sought to identify the risk factors for pneumonitis with CRT-ICI therapy in LA-NSCLC cases and determine its impact on survival. MATERIALS AND METHODS We conducted a retrospective chart review of 140 patients with LA-NSCLC who underwent curative-intent CRT-ICI with durvalumab between 2018 and 2021. Pneumonitis was diagnosed by a multidisciplinary team of clinical experts. We used multivariable cause-specific hazard models to identify risk factors associated with grade ≥2 pneumonitis. We constructed multivariable Cox proportional hazard models to investigate the impact of pneumonitis on all-cause mortality. RESULTS The median age of the cohort was 67 years; most patients were current or former smokers (86%). The cumulative incidence of grade ≥2 pneumonitis was 23%. Among survivors, 25/28 patients had persistent parenchymal scarring. In multivariable analyses, the mean lung dose (hazard ratio 1.14 per Gy, 95% confidence interval 1.03-1.25) and interstitial lung disease (hazard ratio 3.8, 95% confidence interval 1.3-11.0) increased the risk for pneumonitis. In adjusted models, grade ≥2 pneumonitis (hazard ratio 2.5, 95% confidence interval 1.0-6.2, P = 0.049) and high-grade (≥3) pneumonitis (hazard ratio 8.3, 95% confidence interval 3.0-23.0, P < 0.001) were associated with higher all-cause mortality. CONCLUSIONS Risk factors for pneumonitis in LA-NSCLC patients undergoing CRT-ICI include the mean radiation dose to the lung and pre-treatment interstitial lung disease. Although most cases are not fatal, pneumonitis in this setting is associated with markedly increased mortality.

Abstract
PURPOSE/OBJECTIVE(S) Local consolidative radiotherapy (LCT) for oligometastatic disease is a promising paradigm improving outcomes for various malignancies but has been underexplored for metastatic thyroid cancer. We hypothesize that LCT to distant sites with definitive RT doses can yield favorable outcomes and defer systemic therapy escalation for these patients. MATERIALS/METHODS We reviewed 96 thyroid cancer patients who received 175 LCT courses from 2010-2022 to 228 metastatic sites, including: thorax (45%), bone (40%), brain (6%), head/neck (5%), and abdomen (3%). Common prescriptions were 50-55Gy/4-5fxs or 56-70Gy/8-10fxs for lung; 52.5-60Gy/15fxs for mediastinum; and 18-24Gy/1fx or 27-30Gy/3fxs for bone. RECIST v1.1 and CTCAE v5.0 were used to define progression and toxicities, respectively. Outcomes were evaluated via Kaplan-Meier and associations examined via Cox proportional hazards modeling. RESULTS Median age was 63 years (range: 26-92), with 62 oligometastatic cases (total 1-5 sites) and 34 oligoprogressive (with 1-5 growing sites). Primary disease was controlled in all patients, with 39% receiving post-op RT and 66% prior RAI. Histologies included papillary (40%), anaplastic (25%), follicular (12%), medullary (9%), Hurthle (7%), and poorly-differentiated (7%). Median time from initial diagnosis to LCT was 3 yrs (IQR 1-8), and median follow-up from 1st LCT was 21 mos (IQR 9-51). Patients received an average 2 LCT courses (range 1-8) treating 1-4 sites. Median survival (OS) from 1st LCT was 9 yrs (95% CI = 5-14). On multivariable analysis (MVA), worse OS was associated with anaplastic histology (HR 4.6, p<.01), but longer OS was associated with prior RAI (HR 0.33, p = .02) and oligometastatic disease (HR 0.3, p = .01). For anaplastic histology, median OS was 1.2 years vs. 9.3 years for non-anaplastic; 3-yr OS was 36% vs. 88% (log-rank, p<.01). Five-year OS for oligometastatic cases was 75% vs 53% for oligoprogressive (log-rank, p = .04). Median progression free survival (PFS) from 1st LCT was 15.5 mos (95% C I = 11-20). On MVA for all LCT courses, time to any progression (TTP) was negatively associated with anaplastic histology (HR 1.7, p = .02) and 2nd or higher LCT course (HR 1.45, p = .05), but favorably associated with thoracic site (HR 0.49, p<.01). Following later LCT courses, median TTP was 11 mos vs 17 mos for initial LCT course (log-rank, p = .03). After LCT to lung/chest, TTP was 18.6 mos vs 9.5 mos for non-thoracic sites (log-rank, p<.01). Only 6% of failures occurred at previously treated lesions. Most LCT courses (67%) were without ongoing chemotherapy, while 25% entailed continuing the same regimen and 9% had planned treatment post-RT. There were 2 Grade 3 toxicities (pneumonitis and esophagitis) and no Grade 4-5 events. CONCLUSION With high local control rates and minimal toxicity, LCT can be a feasible strategy to defer systemic therapy escalation for oligometastatic and oligoprogressive thyroid cancer.

Abstract
PURPOSE/OBJECTIVE(S) To investigate comorbidities and their impact on treatment tolerance and survival for elderly NSCLC patients treated with concurrent chemoradiation using proton beam therapy (PBT) or intensity modulated radiation therapy (IMRT) followed by immunotherapy (IO). MATERIALS/METHODS This is a retrospective study in senior patients (≥ 65 years) with inoperable locally advanced- NSCLC (LA-NSCLC) who received concurrent chemoradiation (CRT) therapy followed by adjuvant IO. Comorbidities are listed in table 1 and scored according to hazard ratios (HRs) of death. Treatment tolerance and comorbidities were compared between modalities using Fisher's exact test. Association between comorbidities and treatment tolerance was analyzed using logistic regression; association between comorbidities and survival was analyzed by Cox proportional hazards regression. RESULTS Total 218 patients were included with median age of 72 (range 65-86) years. Fifty-three (24.3%) were PBT and 165 (75.7%) were IMRT. Majority patients were white ethnics, had stage III adenocarcinoma disease and good performance score, and received RT dose 60-66 Gy. The median follow-up time for the whole group was 23 months. A 97% of patients had ≥1, and 62% had ≥4 comorbidities. The combined comorbidity scores ranged from 0 to 25. No significant difference in comorbidities between modalities except IMRT had more patients with COPD (36% vs. 51%, p = 0.047). Rates of hospitalization and ER visit during CRT+IO were 28% and 5%, respectively. Rates of IO discontinuation and interruption were 55% and 8%, respectively. Patients received >6 months IO had significantly lower risk of death (HR: 0.25, p<0.001). No significant difference in treatment tolerance between modalities. In multivariable analysis, atrial fibrillation, pulmonary disease, and depression were the comorbidities associated with hospitalization during CRT+IO (p<0.05); dementia was the comorbidity associated with IO interruption (p = 0.042); heart failure, COPD, asthma, osteoporosis and HIV were the comorbidities associated with poor OS (p<0.05). Combined comorbidity score was associated with OS with HR of 1.13 (p<0.001) with adjustment of race, GTV and induction chemotherapy. CONCLUSION Comorbidities were associated with hospitalization and IO interruption during the whole course of CRT and IO therapy, with increased IO discontinuation which negatively impacted survival. Evaluating and scoring comorbidities at diagnosis could be a useful method to predict risk of death before treatment start.

Abstract
PURPOSE/OBJECTIVE(S) Trimodality therapy with chemoradiation (CRT) followed by esophagectomy is the standard of care for locally advanced esophageal cancer. An unresolved question is whether pathologic complete response (pCR) can be assessed non-invasively for patients post-CRT. In this study, we assessed whether diffusion-weighted imaging (DWI) with MRI or PET can be used as predictors of pCR and other clinical outcomes after CRT. MATERIALS/METHODS Patients were enrolled on a single-arm institutional trial (PA13-0380) assessing the role of imaging in predicting outcomes in potentially resectable esophageal patients undergoing trimodality therapy. All patients received neoadjuvant CRT, and 29 patients had subsequent surgery. DWI MRI and PET scans were obtained at baseline, 2 weeks after the start of CRT (interim) and 4 to 6 weeks after completion of CRT (follow up). Apparent diffusion coefficients (ADCs) were calculated based on DWI images. Circulating tumor DNA was obtained for 27 patients post-radiation using CAPP-Seq. Mann-Whitney tests compared imaging changes associated with pCR. Discrimination of pCR by imaging changes was quantified by received operating characteristics. Youden's index was applied to select optimal thresholds. Kaplan-Meier analysis was performed to assess differences in overall survival (OS) and progression-free survival (PFS) by changes in DWI, PET, and ctDNA parameters. RESULTS Our cohort of 60 patients had a median follow up of 42.7 months, age of 65.4 yrs, and ECOG of 1 at completion of CRT. 90% were male, 58% had a history of smoking, and 85% were white. 83% had adenocarcinoma with the rest squamous cell carcinoma. Stages of the patients ranged from IIA to IIIB. All had moderately (47%) or poorly (53%) differentiated disease. All received 41.4-50.4 Gy in 1.8 Gy fractions with the majority receiving 50.4 Gy (95%). 29 patients underwent surgery after CRT of which 8 (27.6%) had pCR. Mean ΔADC from baseline to mid-treatment was most associated with pCR (AUC = 0.98, p<0.001) for patients undergoing surgery. Max ΔADC from baseline to first follow-up was most associated with OS (p = 0.002) and PFS (p<0.001) for the whole cohort. 27 patients had ctDNA analyzed after RT with the presence of ctDNA significantly associated with worse OS (HR = 0.12, p = 0.05) and PFS (HR = 0.10, p = 0.002). Combining ctDNA and max ΔADC generated a model that was more predictive of OS and PFS than either alone. We found that neither the PET parameters of TLG or SUV max at baseline or changes in these parameters from baseline to mid-treatment or first follow-up were as predictive as DWI. CONCLUSION We show that changes in DWI is associated with pCR, OS, and PFS in resectable esophageal cancer patients undergoing CRT. DWI was more predictive than PET and a model combining DWI and ctDNA was the most predictive of clinical outcomes. This study shows the significant promise of using DWI in potentially guiding treatment decisions in esophageal cancer patients and will require validation in a larger cohort.

Abstract
PURPOSE OF REVIEW Immune checkpoint inhibitors (ICIs) are the frontline of therapy for most cancers. Although ICIs are sometimes considered to be less harmful than systemic chemotherapies, ICIs may cause immune-related adverse events, which are cases of off-target inflammation in healthy tissues. Pneumonitis, an immune-related adverse event, is the leading cause of therapy-related mortality with ICIs. The aim of this review is to discuss how preexisting interstitial lung disease (ILD) and thoracic radiation increase the risk for ICI-pneumonitis. We discuss potential mechanisms of lung injury and how pneumonitis may impact cancer treatments. RECENT FINDINGS Preexisting ILD and thoracic radiation are major risk factors for ICI-pneumonitis. The mechanisms of injury are still not fully understood but may involve the same inflammatory and profibrotic cytokines as those seen in sporadic ILD. Thoracic radiation increases the risk for ICI-pneumonitis and may synergize with preexisting ILD to worsen toxicity. SUMMARY Preexisting ILD and thoracic radiation may increase the risk for the future development of ICI-pneumonitis. However, while these should not preclude potentially life-saving immunotherapy, in some cases, an alternative treatment strategy may be advisable. A multidisciplinary approach is required involving oncologists, pulmonologists, and radiation oncologists to guide in the selection of cancer treatment and in the diagnosis and treatment of pneumonitis.

Abstract
BACKGROUND Only around 20-30% of patients with non-small-cell lung cancer (NCSLC) have durable benefit from immune-checkpoint inhibitors. Although tissue-based biomarkers (eg, PD-L1) are limited by suboptimal performance, tissue availability, and tumour heterogeneity, radiographic images might holistically capture the underlying cancer biology. We aimed to investigate the application of deep learning on chest CT scans to derive an imaging signature of response to immune checkpoint inhibitors and evaluate its added value in the clinical context. METHODS In this retrospective modelling study, 976 patients with metastatic, EGFR/ALK negative NSCLC treated with immune checkpoint inhibitors at MD Anderson and Stanford were enrolled from Jan 1, 2014, to Feb 29, 2020. We built and tested an ensemble deep learning model on pretreatment CTs (Deep-CT) to predict overall survival and progression-free survival after treatment with immune checkpoint inhibitors. We also evaluated the added predictive value of the Deep-CT model in the context of existing clinicopathological and radiological metrics. FINDINGS Our Deep-CT model demonstrated robust stratification of patient survival of the MD Anderson testing set, which was validated in the external Stanford set. The performance of the Deep-CT model remained significant on subgroup analyses stratified by PD-L1, histology, age, sex, and race. In univariate analysis, Deep-CT outperformed the conventional risk factors, including histology, smoking status, and PD-L1 expression, and remained an independent predictor after multivariate adjustment. Integrating the Deep-CT model with conventional risk factors demonstrated significantly improved prediction performance, with overall survival C-index increases from 0·70 (clinical model) to 0·75 (composite model) during testing. On the other hand, the deep learning risk scores correlated with some radiomics features, but radiomics alone could not reach the performance level of deep learning, indicating that the deep learning model effectively captured additional imaging patterns beyond known radiomics features. INTERPRETATION This proof-of-concept study shows that automated profiling of radiographic scans through deep learning can provide orthogonal information independent of existing clinicopathological biomarkers, bringing the goal of precision immunotherapy for patients with NSCLC closer.

Abstract
The combination of radiation therapy (RT) and immunotherapy has emerged as a promising treatment option in oncology. Historically, x-ray radiation (XRT) has been the most commonly used form of RT. However, proton beam therapy (PBT) is gaining recognition as a viable alternative, as it has been shown to produce similar outcomes to XRT while minimizing off-target effects. The effects of PBT on the antitumor immune response have only just begun to be described, and to our knowledge no studies to date have examined the effect of PBT as part of a combinatorial immunoradiotherapeutic strategy. Here, using a 2-tumor model of lung cancer in mice, we show that PBT in tandem with an anti-PD1 antibody substantially reduced growth in both irradiated and unirradiated tumors. This was accompanied by robust activation of the immune response, as evidenced by whole-tumor and single-cell RNA sequencing showing upregulation of a multitude of immune-related transcripts. This response was further significantly enhanced by the injection of the tumor to be irradiated with NBTXR3 nanoparticles. Tumors of mice treated with the triple combination exhibited increased infiltration and activation of cytotoxic immune cells. This triple combination eradicated both tumors in 37.5% of the treated mice and showed robust long-term immunity to cancer.

Abstract
Abstract
Introduction: Immunoradiotherapy combining radiotherapy and immune checkpoint blockade, has achieved impressive treatment outcomes. We have previously demonstrated that photon (XRT) and proton (PRT) localized radiotherapy in combination with immune checkpoint blockade and NBTXR3, a radioenhancing nanoparticle, could induce a systemic antitumor immune response. However, no studies have compared the treatment efficacy of PRT and XRT immunoradiotherapy. Here, we compared the capabilities of PRT and XRT when combined with NBTXR3 and PD1 blockade for inducing an antitumor immune response.
Methods: 344SQR cells were inoculated in the right and left hindlimbs of 129Sv/Ev mice on day 0 and day 4 to establish primary and secondary tumors, respectively. Mice were divided into five treatment groups: 1) untreated control; 2) XRT+αPD1; 3) NBTXR3+XRT+αPD1; 4) PRT+αPD1; 5) NBTXR3+PRT+αPD1. The primary tumors were intratumorally injected with NBTXR3 nanoparticles on day 7, followed by two fractions of 12 Gy XRT or PRT on days 8 and 9 (total dose of 24 Gy). Two hundred μg of αPD1 was given to the mice on days 7, 10, 14, 21, 28, 35, and 42 through intraperitoneal injection. We assayed whole tumor RNAs with a Nanostring pan-cancer immune panel to profile the tumor immune microenvironment changes. In addition, immune cells extracted from the tumors were analyzed with single-cell RNA sequencing (scRNAseq). The survivor mice treated with the NBTXR3+PRT+αPD1 were rechallenged with 344SQR and 344SQP cells.
Results: PRT+ αPD1 resulted in significantly better control of the primary tumors than XRT+ αPD1. No significant difference was observed in the volume of the secondary tumors treated with XRT+ αPD1 and the control. In contrast, PRT+ αPD1 resulted in a pronounced abscopal effect. Adding NBTXR3 to XRT+ αPD1 and PRT+ αPD1 improved the control of both the primary and secondary tumors. In addition, NBTXR3+PRT+αPD1 achieved significantly slower growth of the two tumors and more prolonged survival than NBTXR3+XRT+αPD1. Remarkably, NBTXR3+PRT+αPD1 eradicated both primary and secondary tumors in 40% of the treated mice, while no mice were cured by NBTXR3+XRT+αPD1. Nanostring analysis and scRNAseq revealed better activation and infiltration of antitumoral immune cells to the two tumors when treated with PRT than XRT. The survivor mice treated with NBTXR3+PRT+αPD1 effectively rejected tumor growth after rechallenge with 344SQR and 344SQP cells.
Conclusions: When combined with NBTXR3, PRT with αPD1 exhibited significantly better treatment efficacy than XRT with αPD1. The superior efficacy of NBTXR3+PRT+αPD1 is accompanied by a more robust immune activation and immune cell infiltration in irradiated and unirradiated tumors.

Abstract
BACKGROUND AND PURPOSE MR imaging of the brain provides unbiased neuroanatomic evaluation of brain injury and is useful for neurologic prognostication following cardiac arrest. Regional analysis of diffusion imaging may provide additional prognostic value and help reveal the neuroanatomic underpinnings of coma recovery. The purpose of this study was to evaluate global, regional, and voxelwise differences in diffusion-weighted MR imaging signal in patients in a coma after cardiac arrest. MATERIALS AND METHODS We retrospectively analyzed diffusion MR imaging data from 81 subjects who were comatose for >48 hours following cardiac arrest. Poor outcome was defined as the inability to follow simple commands at any point during hospitalization. ADC differences between groups were evaluated across the whole brain, locally by using voxelwise analysis and regionally by using ROI-based principal component analysis. RESULTS Subjects with poor outcome had more severe brain injury as measured by lower average whole-brain ADC (740 [SD, 102] × 10-6 mm2/s versus 833 [SD, 23] × 10-6 mm2/s, P < .001) and larger average volumes of tissue with ADC below 650 × 10-6 mms/s (464 [SD, 469] mL versus 62 [SD, 51] mL, P < .001). Voxelwise analysis showed lower ADC in the bilateral parieto-occipital areas and perirolandic cortices for the poor outcome group. ROI-based principal component analysis showed an association between lower ADC in parieto-occipital regions and poor outcome. CONCLUSIONS Brain injury affecting the parieto-occipital region measured with quantitative ADC analysis was associated with poor outcomes after cardiac arrest. These results suggest that injury to specific brain regions may influence coma recovery.

Abstract
The efficacy of immunoradiotherapy consisting of radiation therapy and immune checkpoint blockade relies on effectively promoting the systemic antitumor immune response's activation while simultaneously reducing local factors favoring immune suppression. We previously demonstrated that NBTXR3, a nanoparticle radioenhancer, significantly improved immune responses in a murine anti-PD1-resistant metastatic lung cancer model. We hypothesize that radioactivated-NBTXR3 addition to anti-PD1 and a second-generation anti-CTLA4 could improve treatment effectiveness. To test this hypothesis, we inoculated mice with 344SQR cells in the right and left legs to establish primary and secondary tumors. The primary tumors were intratumorally injected with NBTXR3 nanoparticles on day 7, followed by three fractions of 12 Gy radiation on days 8, 9, and 10. The secondary tumors received two fractions of 1Gy radiation on days 13 and 14. Multiple rounds of anti-PD1, anti-CTLA4 or nonfucosylated anti-CTLA4 were given to the mice. Immune profiling of the tumors revealed that the combination of NBTXR3 with immunoradiotherapy significantly upregulated the activities of a wide range of antitumor immune pathways and reduced the abundance of regulatory suppressor T cells. This combination effectively eradicated the primary and secondary tumors and increased animal survival to 75%. Remarkably, previously treated with NBTXR3-containing treatment, the survivor mice exhibited a long-lasting antitumor memory immune response. This data provides compelling evidence of the efficacy of NBTXR3 to synergize with the immunoradiotherapy approach when combined with an anti-PD1 and multiple checkpoints such as a second generation anti-CTLA4 and show the potential for clinical uses of antitumor immunomodulatory effects of NBTXR3.

Abstract
PURPOSE We compared treatment-related pulmonary adverse events (TRPAE), progression-free survival (PFS), and overall survival (OS) among locally advanced non-small cell lung cancer (NSCLC) patients who received concurrent chemoradiotherapy (CRT) versus CRT followed by immune check point inhibitor (ICI) immunotherapy (CRTI). MATERIALS AND METHODS TRPAE was defined as any pulmonary events as defined in CTCAE v.5 occurring within 12 months after completion of radiotherapy. Outcomes were compared between CRT and CTRI by Cox proportional hazard regression and Kaplan-Meier analyses. We also assessed if TRPAE-induced discontinuation of ICI affected survival. RESULTS We analyzed 326 patients treated between July 2010 and November 2019; 195 patients received CRT and 131 received CRTI. The incidences of severe grade ≥ 3 TRPAE were similar between the two groups, however, symptomatic TRPAE was almost doubled in CRTI group (65.7 % CTRI vs 35.9 % CRT, P < 0.0001). The rates of 4-year OS and PFS were 54.5 % vs 36.7 % (P = 0.0003) and 43.8 % vs 35.8 % (P = 0.038) in CRT + Durvalumab and CRT group, respectively. Receipt of ICI Durvalumab was associated with better 4-year OS (HR 0.53, 95 % CI 0.36-0.78, P = 0.001) and PFS (HR 0.55, 95 % CI 0.38-0.80, P = 0.002). Patients who discontinued ICI because of TRPAE had worse 4-year OS (P = 0.001) and higher rates of distant metastasis (P = 0.003) than those who completed planned ICI after developing TRPAE. CONCLUSION CRT followed by adjuvant ICI led to improved 4-year OS and PFS consistent with published data. CRTI was associated with higher incidence of grade ≥ 2 TRPAE in both high and low mean lung dose groups without significant difference in grade ≥ 3 TRPAE. Discontinuation of ICI due to TRPAE was associated with poorer OS and distant disease control than completing ICI as planned after developing TRPAE.

Abstract
UNLABELLED In an Ontario fracture liaison service (FLS), we compared medication prescription rates among patients not taking a previously prescribed bone active medication to those with no previous prescription. Prescription rates were similar between these two groups of patients. The FLS provided a secondary opportunity for patients to initiate bone active medication. PURPOSE We compared bone active medication prescription rates among patients presenting to an Ontario fracture liaison service (FLS) who reported not taking a previously prescribed bone active medication to those with no history of prescription. METHODS Eligible patients were those screened in 39 fracture clinics between July 1, 2017, and September 15, 2019, who were not taking bone active medication at the time of screening and classified as high risk for future fracture based on CAROC or FRAX. Sociodemographic and clinical risk factor variables were assessed at screening. Bone active medication prescription rate was assessed within 6 months of screening and defined as having received a prescription for the medication from either a specialist or primary care provider. In cases where a specialist report was not available, patient self-reported data were collected. The chi-square test of independence was used to assess differences in prescription rates. RESULTS Of 17,575 patients screened, eligible patients were 350 with a previous prescription and 2644 without a previous prescription. Compared with patients who reported no previous prescription, those who had a previous prescription were older, more likely to be female and to report a previous fracture, and less likely to smoke. There was no statistically significant difference between the medication prescription rate of patients with a previous prescription (73.7%) compared to patients with no previous prescription (70.7%) (p = 0.157). CONCLUSION A large jurisdiction-wide FLS approach provided a secondary opportunity to patients who were not taking a previously prescribed bone active medication to initiate that medication.

Abstract
BACKGROUND While improvements in immunoradiotherapy have significantly improved outcomes for cancer patients, this treatment approach has nevertheless proven ineffective at controlling the majority of malignancies. One of the mechanisms of resistance to immunoradiotherapy is that immune cells may be suppressed via the myriad of different immune checkpoint receptors. Therefore, simultaneous blockade of multiple immune checkpoint receptors may enhance the treatment efficacy of immunoradiotherapy. METHODS We combined NBTXR3-enhanced localized radiation with the simultaneous blockade of three different checkpoint receptors: PD1, LAG3, and TIGIT, and tested the treatment efficacy in an anti-PD1-resistant lung cancer model in mice. 129 Sv/Ev mice were inoculated with fifty thousand αPD1-resistant 344SQR cells in the right leg on day 0 to establish primary tumors and with the same number of cells in the left leg on day 4 to establish the secondary tumors. NBTXR3 was intratumorally injected into the primary tumors on day 7, which were irradiated with 12 Gy on days 8, 9, and 10. Anti-PD1 (200 µg), αLAG3 (200 µg), and αTIGIT (200 µg) were given to mice by intraperitoneal injections on days 5, 8, 11, 14, 21, 28, 35, and 42. RESULTS This nanoparticle-mediated combination therapy is effective at controlling the growth of irradiated and distant unirradiated tumors, enhancing animal survival, and is the only one that led to the destruction of both tumors in approximately 30% of the treated mice. Corresponding with this improved response is robust activation of the immune response, as manifested by increased numbers of immune cells along with a transcriptional signature of both innate and adaptive immunity within the tumor. Furthermore, mice treated with this combinatorial therapy display immunological memory response when rechallenged by the same cancer cells, preventing tumor engraftment. CONCLUSION Our results strongly attest to the efficacy and validity of combining nanoparticle-enhanced radiotherapy and simultaneous blockade of multiple immune checkpoint receptors and provide a pre-clinical rationale for investigating its translation into human patients.

Abstract
Abstract
Background
Anastomotic leak (AL) is a common but severe complication after oesophagectomy. It is unknown how to determine the severity of AL objectively at diagnosis. Determining leak severity may guide treatment decisions and improve future research. This study aimed to identify leak-related prognostic factors for mortality, and to develop a Severity of oEsophageal Anastomotic Leak (SEAL) score.
Methods
This international, retrospective cohort study in 71 centres worldwide included patients with AL after oesophagectomy between 2011 and 2019. The primary endpoint was 90-day mortality. Leak-related prognostic factors were identified after adjusting for confounders and were included in multivariable logistic regression to develop the SEAL score. Four classes of leak severity (mild, moderate, severe, and critical) were defined based on the risk of 90-day mortality, and the score was validated internally.
Results
Some 1509 patients with AL were included and the 90-day mortality rate was 11.7 per cent. Twelve leak-related prognostic factors were included in the SEAL score. The score showed good calibration and discrimination (c-index 0.77, 95 per cent c.i. 0.73 to 0.81). Higher classes of leak severity graded by the SEAL score were associated with a significant increase in duration of ICU stay, healing time, Comprehensive Complication Index score, and Esophagectomy Complications Consensus Group classification.
Conclusion
The SEAL score grades leak severity into four classes by combining 12 leak-related predictors and can be used to the assess severity of AL after oesophagectomy.

Abstract
Abstract
Introduction: Checkpoint inhibition (CPI) has been a game-changer for cancer therapy, but most cancers do not respond. Part of the problem is that cancers employ multiple checkpoints; thus, targeting multiple checkpoint receptors simultaneously may yield increased benefit. Previously, we found that radiotherapy (XRT) in concert with a radiation-enhancing nanoparticle (NBTXR3) and PD1 blockade significantly improved tumor control both at the irradiative site and in remote, unirradiated tumors in a mouse model of anti-PD1 (αPD1)-resistant lung cancer (344SQR). Here, we tested whether blockade of TIGIT, LAG3, and PD1 in combination with NBTXR3-enhanced XRT could improve antitumor immune responses in our 344SQR tumor model.
Methods: Fifty thousand 344SQR cells were inoculated in the right and left hindlimbs of 129Sv/Ev mice on day 0 and day 4 to establish primary and secondary tumors, respectively. Mice were divided into six treatment groups: 1) untreated; 2) XRT+αPD1; 3) NBTXR3+XRT+αPD1; 4) NBTXR3+XRT+αPD1+αLAG3; 5) NBTXR3+XRT+αPD1+αTIGIT; and 6) NBTXR3+XRT+αPD1+αLAG3 +αTIGIT. Primary tumors were intratumorally injected with NBTXR3 nanoparticles on day 7 and received 3 fractions of 12 Gy X-ray radiation on days 8, 9, and 10. Immune checkpoint inhibitors, composed of αPD1 (200 μg), αLAG3 (200 μg), and αTIGIT (200 μg), were intraperitoneally administered to the mice on days 5, 8, 11, 14. The expression of 770 immune-related genes were measured via NanoString from the RNA extracted from the primary and secondary tumors on day 21.
Results: CPIs+NBTXR3-enhanced radiation significantly promoted the upregulation of mRNA transcripts involved in innate immunity, the humoral response, B cell function, dendritic cell (DC) function, and antigen processing within primary, irradiated tumors relative to untreated controls. No additional increase in immune gene activity in the irradiated tumors was observed when LAG3, TIGIT, or both were blocked in addition to PD1. However, within the non-irradiated tumors, triple blockade of PD1, LAG3, and TIGIT in concert with NBTXR3+XRT produced elevations in multiple immune-related pathways that were significantly higher than those produced by other treatment combinations. These pathways included both adaptive and innate immunity; B, T, and natural killer (NK) cell, and DC function; and antigen processing.
Conclusions: Simultaneous inhibition of LAG3 and TIGIT in tandem with PD1 blockade and NBTXR3-enhanced radiotherapy promotes immune activation at the irradiated site. In addition, abscopal immune responses are improved with blockade of LAG3 and TIGIT. These results suggest that blockade of multiple immune checkpoints in parallel with NBTXR3-mediated radiotherapy may be effective in metastatic cancers.

Abstract
2554 Background: Certain immune-related adverse events (irAEs) that emerge with immune checkpoint blockade share clinical features of autoimmune conditions. Preexisting auto-reactive antibodies and their contribution to irAEs have not been well defined, and observations are limited. Methods: We longitudinally collected patient plasma samples from a clinical trial that combines immune checkpoint inhibitors, Ipilimumab, and Nivolumab (I+N) with subsequent radiation therapy (Lonestar, NCT03391869). Plasma samples were collected at baseline, after 12 weeks of I+N (induction), and at the time of Grade ≥ 2 pneumonitis (CTCAEv5.0). Auto reactive antibody profiles were analyzed using a fluorescence-based assay system that measures more than 130 antigens and is capable of assaying antibody reactivity for IgG and IgM fractions, including nuclear-cytosolic and tissue-specific antigens. Selected antibodies had a reportable result range, reference intervals, and reproducibility with quality controls. A paired t-test was used to compare the mean of longitudinally collected baseline and toxicity samples. An unpaired t-test was used to compare differences between groups. The False Discovery Rate was used to control the Type I error rate of multiple comparisons. Results: In the study cohort, G≥2 pneumonitis was observed in 11 patients out of 194 (5.6%). Serum was collected at baseline for all 11 patients, and 9 of the 11 patients had a serum sample collected at the time of pneumonitis event. Longitudinal serum samples (baseline and post-induction) collected from 32 patients without any irAEs were used as control. At baseline AChR3 and calmodulin antibodies were elevated in patients who developed pneumonitis, compared with baseline samples from controls (p≤0.05). At the time of pneumonitis IgM antibodies against AChR3, CXCL10, NSE, BAFF, CA242, Cytokeratin 19 were noted to be elevated in serum for pneumonitis cases compared with post induction samples from control (p≤0.005). Conclusions: We identified auto reactive antibodies associated with a higher risk of immunotherapy associated pneumonitis in patients treated with ipilimumab and nivolumab. These included auto reactive antibodies against proteins associated with lung injury (AChR3), lung inflammation (BAFF, CXCL10) and against alveolar epithelium (Cytokeratin 19). Future studies are warranted to determine if auto-reactive antibodies can be used as pre-treatment risk markers or to diagnose pneumonitis and may offer insights into to mechanisms that predispose toward pneumonitis.

Abstract
9049 Background: Primary resistance to immune checkpoint inhibitor (ICI) therapy remains a major challenge in clinical oncology. Here, we describe the clinical outcome of patients who experienced radiologic progression within 12 weeks of therapy with nivolumab and ipilimumab (I+N) for metastatic non-small cell lung cancer (mNSCLC). Methods: The LONESTAR study is an ongoing phase III study (NCT03391869). Study enrolls patients with immunotherapy naïve mNSCLC (prior chemotherapy is allowed). All patients receive I+N for 12 weeks and are randomized to experimental therapy vs. control arm if they did not have disease progression. Patients who experience radiologic progression per RECIST v1.1 are not randomized and removed from the study. Treatment beyond progression is allowed if they clinically benefit from the systemic therapy. We prospectively collected clinicopathologic and radiologic outcome data from patients who experienced radiologic progression within 12 weeks of I+N therapy and have not randomized to investigational therapy. We described the primary progression pattern. We collected subsequent treatment, radiologic, and toxicity data and calculated clinical outcomes, including progression-free survival (PFS) and overall survival (OS). Results: Of the 194 patients who received at least one dose of I+N therapy, 72 patients had clinical and/or radiologic progression at ≤ 12 weeks. Thirty-five (35; 48%) patients did not receive subsequent treatment, 21 (29%) patients received subsequent 2nd line systemic therapy, and 16 (22%) patients were continued on I+N beyond radiologic progression due to ongoing clinical benefit. Among patients treated with 2nd line therapy, 13 patients were treated with platinum doublet +/- anti-PD-(L)1, seven (7) patients were treated with single-agent chemotherapy +/- VEGF inhibitor, and one (1) patient was treated with targeted therapy. The PFS for the 2nd line therapy was 6.5 months (95%CI: 4.8, 8.9), and OS was 10.4 months (95%Cl: 6.6, 16.1). Among the 16 patients treated with I+N beyond progression, 13 had a mixed response to induction therapy, where primary progression was most frequently observed in mediastinal lymph nodes. LCT with radiotherapy was utilized with I+N in 10 patients. The median duration of post-progression treatment with I+N plus LCT was 8.7 months (95%Cl: 5.9, 22.3) and 5.6 months (95%Cl 4.4, 11.5) with I+N alone. The OS was 19.5 months (95% CI: 6.2,18.7). Conclusions: In this study cohort, primary resistance to I+N was observed in 37% of the patients, and in a subset of these patients treated with post-progression I+N, either alone or in combination with LCT, durable clinical benefit was observed. Further studies are warranted to identify which patients are most likely to benefit from post-progression I+N. Clinical trial information: NCT03391869.

Abstract
12112 Background: Systemic corticosteroids are commonly prescribed for palliation of dyspnea in patients with cancer; however, evidence to support their use is limited. A small RCT suggested that dexamethasone may be efficacious. In this confirmatory RCT, we compared the effect of high dose dexamethasone and placebo on dyspnea in patients with cancer. Methods: This NCI-funded, multi-site, double-blind, parallel group RCT enrolled ambulatory patients with cancer, age ≥18, dyspnea ≥4/10 and randomly assigned them to receive dexamethasone 8 mg orally every 12 hours for 7 days followed by 4 mg orally every 12 hours for 7 days or matching placebo capsules. Permuted block randomization (block size = 6, 2:1) was conducted, stratified by baseline dyspnea and study site. Patients, research staff and clinicians were blinded. The primary outcome was change in average dyspnea intensity assessed with a 0-10 numeric rating scale (0 = none, 10 = worst) between baseline and day 7. Secondary outcomes included the Edmonton Symptom Assessment Scale (ESAS) and adverse effects (CTCAE v4.02). Intention-to-treat analysis was conducted with linear models to compare between groups. The planned sample size of 201 patients provided 80% power to detect a mean difference of 1.0 between treatment groups with a two-sided α of 5%, assuming a standard deviation of 2.0 and 15% attrition. (Clinicaltrials.gov NCT03367156). Results: Between 1/11/2017 and 4/23/2021, we enrolled 149 patients and 128 received the blinded study interventions (dexamethasone n = 85, placebo n = 43). Enrollment was terminated early by the Data Safety Monitoring Board when futility criterion was met in pre-planned interim analysis. The mean change in dyspnea NRS intensity between baseline and day 7 was -1.6 (95% CI -2, -1.2) in the dexamethasone group and -1.6 (95% CI -2.3, -0.9) in the placebo group, with no significant between-group difference (mean 0, 95% CI -0.8, 0.7; P = 0.91). Secondary analyses showed that the dexamethasone group had a significantly better ESAS appetite (mean difference -1.2, 95% CI -2.2, -0.1; P = 0.03) and well being (mean -1, 95% CI -1.8, -0.2; P = 0.02), and worse ESAS anxiety (mean 1.1, 95% CI 0.3, 1.9; P = 0.01) and depression (mean 0.9, 95% CI 0.1, 1.7; P = 0.02) compared to placebo. Similar magnitude of changes in dyspnea and ESAS symptoms were observed by day 14. Adverse effects were reported more frequently in the dexamethasone group (any grade): insomnia (38% v. 12%), neuropsychiatric symptoms (31% vs. 7%), infections (21% v. 12%), dyspepsia (26% v. 12%), edema (18% v. 9%), hiccups (12% v. 7%), flushing (9% v. 5%) and respiratory distress (6% v. 0%). More patients in the dexamethasone group required hospitalization within 30 d of last study medication (25% vs. 7%, P = 0.02). Conclusions: High dose dexamethasone did not improve dyspnea in patients with cancer more than placebo and was associated with more adverse events. Clinical trial information: NCT03367156.

Abstract
8513 Background: In advanced non-small cell lung cancer (NSCLC), high Programmed-Death-1 Ligand (PD-L1) (>50%) expression demonstrate superior response and survival with immune checkpoint inhibitors compared to chemotherapy. We hypothesize that it is safe and feasible to substitute durvalumab instead of chemotherapy concurrently with radiotherapy (RT) in patients with Locally Advanced-NSCLC (LA-NSCLC) and high PD-L1. Methods: NRG-LU004 (NCT03801902) is a Phase I study for patients with stage II-III unresectable or inoperable, LA-NSCLC with PD-L1> 50% (Dako 22C3 or Ventana SP263) expression. There were safety and expansion phases with a primary endpoint of safety. Patients started with 1500 mg durvalumab Q4 weeks and thoracic RT within 2 weeks from 1st infusion. Durvalumab continued once a month up to 1 year. In the safety cohort, 6 patients in cohort 1 were treated with accelerated fractionated RT (ACRT) to 60 Gy in 15 fractions, followed by a required safety hold for 90 days. During cohort 1 safety hold, cohort 2 patients were treated with conventional RT 60 Gy in 30 fractions (CONV) followed by a 60-day safety hold. A cohort advanced to the expansion phase to enroll 6 more patients if safety criteria (0-1 patients with a dose limiting toxicity [DLT]) were met. If both cohorts were deemed safe, patients would be randomized 1:1 to ACRT or CONV with safety defined as < 4 of 12 evaluable patients per arm experiencing a DLT. Feasibility was defined as at least 80% of patients in each arm receiving at least 80% of the planned dose of durvalumab during the first 8 weeks. Results: 24 evaluable patients enrolled between January 2019 and June 2021. No DLTs were reported in cohort 1, and 1 (unrelated bronchopulmonary hemorrhage leading to discontinuation of durvalumab) in cohort 2. Both safety cohorts advanced to the expansion phase. All but one patient (CONV) received RT per protocol/with an acceptable variation. At the time of analysis, 24% had received all 13 cycles of durvalumab. For the ACRT cohort, there were 4 grade 3, 1 grade 4 (lymphopenia), and 1 grade 5 AE (lung infection, assessed as unrelated to therapy). For CONV, there were 8 grade 3, 0 grade 4, and 1 grade 5 AE (respiratory failure, unrelated to therapy). For feasibility, 10 of 12 (85%) patients in the ACRT cohort received the second dose of durvalumab (2 not received due to shingles and unrelated death), while 9 of 12 (75%) of the CONV cohort received the second dose (reasons for not receiving: viral hepatitis, bronchopulmonary hemorrhage, and respiratory failure, all assessed as unrelated to therapy). Conclusions: Chemotherapy-free thoracic RT approaches (ACRT or CONV RT) are safe, when given with concurrent durvalumab in patients with PD-L1 high LA-NSCLC. A trial to compare immunoradiotherapy and consolidation durvalumab to standard chemoradiation and consolidation durvalumab is planned. Clinical trial information: NCT03801902.

Abstract
IMPORTANCE Consolidative durvalumab after definitive chemoradiation for unresectable locally advanced non-small cell lung cancer (NSCLC) can significantly improve progression-free survival (PFS) and overall survival (OS), as shown in the PACIFIC trial. However, whether patients with driver variations derive equal benefit from this regimen remains unclear. OBJECTIVES To compare outcomes of patients with locally advanced NSCLC with and without driver variations treated with the PACIFIC regimen. DESIGN, SETTING, AND PARTICIPANTS This cohort study examined 104 patients with unresectable locally advanced NSCLC with mutational profiling treated at a tertiary cancer center with definitive chemoradiation and consolidative durvalumab from June 2017 through May 2020. Patients with recurrent disease or those receiving postoperative therapy were excluded. Outcomes were analyzed with Kaplan-Meier and multivariate regression analyses. EXPOSURES Patients were grouped according to the presence of non-KRAS driver variations (EGFR exon 19 deletion, EGFR exon 20 insertion, EGFR exon 21 mutation [L858R], ERBB2 exon 20 insertion, EML4-ALK fusion, MET exon 14 skipping, NTRK2 fusion), KRAS driver variations, or no driver variations. MAIN OUTCOMES AND MEASURES The primary outcomes were PFS, OS, and second progression-free survival (PFS2) times. RESULTS The 104 patients had a median (IQR) age of 65.1 (9.8) years, with 55 females (53%) and 85 former or current smokers (88%). There were 43 patients (41%) with driver variations with a median PFS time of 8.4 months vs 40.1 months for patients without driver variations (hazard ratio [HR], 2.75; 95% CI, 1.64-4.62; log-rank P < .001). Both patients with non-KRAS and KRAS driver variations had worse PFS. No difference in OS was found between patients with and without driver variations (log rank P = .24). Among the 63 patients who developed progressive disease, those with non-KRAS driver variations had a median PFS2 time of 13.7 months vs 4.4 months for all other patients (HR, 0.37; 95% CI, 0.21-0.64; log-rank P = .001). Rates of overall grade 2 toxic effects or higher did not differ by driver mutation status. CONCLUSIONS AND RELEVANCE In this cohort study, driver variations in patients with unresectable locally advanced NSCLC were associated with significantly shorter PFS time after definitive chemoradiation and consolidative durvalumab. These findings suggest the need to consider additional or alternative treatment options to the PACIFIC regimen for patients with driver variations.

Abstract
Covid-19, a SARS-CoV virus-based disease, was identified in Wuhan, China, in December 2019. Initially, it was considered just an infection of the respiratory system, but due to its transmittable nature, it was declared a pandemic. A variety of treatment options were implemented, including antivirals like remdesvir, favipiravir along with vitamins and antioxidants. Further investigations revealed that the Covid-19 infection results in thrombotic cardiovascular complications, which are the major concern for the increased mortality associated with this disease. This study investigates the in Silico design of hybrid molecules with antiviral and an-tithrombotic properties. A docking study was performed using Autodock Vina software, and binding energies of the designed compounds were determined for papain-like protease (PDB: 3E9S) and 3-chymotrypsin-like cysteine protease (PDB: 6LU7). The docked poses and amino acids interactions were verified using Biovia Discovery studio 4.5. The binding energies of all designed compounds were compared with the standards, Compound RL1 (2-(5-(3-carbamoyl-1H-1,2,4-triazol-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methoxy)-carbonyl)amino)(hydroxy)methyl)carbamoyl)phenyl acetate) and Compound FL2 (8-hydroxy-2-(3-hydroxy-4-methoxyphenyl)-4-oxochroman-6-yl(2-(6-flouro-3-oxo-3,4-dihydropyrazine-2-carboxamido)-1-hydroxy-3-phenylpropyl)carbamate) proved to be promising agents with strong binding interactions. Hybrid molecules that inhibit viral replication, possibly as transition state inhibitors, may be investigated further for use in the treatment of SARS-Co-V infection and its associated complications.

Abstract
Background Combining radiotherapy with PD1 blockade has had impressive antitumor effects in preclinical models of metastatic lung cancer, although anti-PD1 resistance remains problematic. Here, we report results from a triple-combination therapy in which NBTXR3, a clinically approved nanoparticle radioenhancer, is combined with high-dose radiation (HDXRT) to a primary tumor plus low-dose radiation (LDXRT) to a secondary tumor along with checkpoint blockade in a mouse model of anti-PD1-resistant metastatic lung cancer. Methods Mice were inoculated with 344SQR cells in the right legs on day 0 (primary tumor) and the left legs on day 3 (secondary tumor). Immune checkpoint inhibitors (ICIs), including anti-PD1 (200 μg) and anti-CTLA4 (100 μg) were given intraperitoneally. Primary tumors were injected with NBTXR3 on day 6 and irradiated with 12-Gy (HDXRT) on days 7, 8, and 9; secondary tumors were irradiated with 1-Gy (LDXRT) on days 12 and 13. The survivor mice at day 178 were rechallenged with 344SQR cells and tumor growth monitored thereafter. Results NBTXR3 + HDXRT + LDXRT + ICIs had significant antitumor effects against both primary and secondary tumors, improving the survival rate from 0 to 50%. Immune profiling of the secondary tumors revealed that NBTXR3 + HDXRT + LDXRT increased CD8 T-cell infiltration and decreased the number of regulatory T (Treg) cells. Finally, none of the re-challenged mice developed tumors, and they had higher percentages of CD4 memory T cells and CD4 and CD8 T cells in both blood and spleen relative to untreated mice. Conclusions NBTXR3 nanoparticle in combination with radioimmunotherapy significantly improves anti-PD1 resistant lung tumor control via promoting antitumor immune response. Graphical Abstract ![]()

Abstract
BackgroundTIGIT and LAG3 are inhibitory receptors expressed on cytotoxic CD8+ T cells and NK cells and directly inhibit the activation and proliferation of these cells. We proposed that blockade of TIGIT and LAG3 could improve antitumor immune response in a mouse model of anti-PD1 (aPD1)-resistant mice.Methods129Sv/Ev mice were inoculated with 50,000 aPD1-resistant 344SQR cells in the right leg on day 0 (primary tumor) and with 50,000 cells in the left leg on day 4 (secondary tumor). Primary tumors were injected with NBTXR3 radioenhancer nanoparticles on day 7 and irradiated with 12 Gy on days 8, 9, and 10. Anti-PD1, aLAG3, and aTIGIT were given to mice by intraperitoneal injections on days 5, 8, 11, 14, 21, 28, 35, and 42. On day 21, primary tumors, secondary tumors, and blood samples were harvested and analyzed with flow cytometry to evaluate changes in immune cell populations. The RNA extracted from the tumors were also analyzed by Nanostring. Mice in which tumors were completely eradicated were re-challenged with another 50,000 344SQR cells in the right flank at least two months post radiation; no further treatment was given to these mice, and tumor growth was monitored.ResultsThe addition of aTIGIT, aLAG3, or aTIGIT+aLAG3 to NBTXR3+XRT+aPD1 therapy significantly improved control of tumors, and the addition of aTIGIT+aLAG3 also led to fewer spontaneous lung metastases. The addition of either aTIGIT or aLAG3 to NBTXR3+XRT+aPD1 extended mouse survival time relative to NBTXR3+XRT+aPD1. None of the 8 mice in either the NBTXR3+XRT+aPD1+aTIGIT group or the NBTXR3+XRT+aPD1+aLAG3 group survived more than 32 days; in contrast, 3 of the 8 mice that received NBTXR3+XRT+aPD1+aTIGIT+aLAG3 survived until the end of the experiment. These surviving mice were found to have developed memory against 344SQR cells, and no further tumor growth was observed after re-challenge. Flow cytometry analysis showed that adding aTIGIT+aLAG3 to NBTXR3+XRT+aPD1 increased the percentages of proliferating CD8+ T cells in primary tumors, secondary tumors, and blood. Furthermore, Nanostring transcriptomic analysis of cells isolated from the tumors of mice thus treated showed evidence of classical two-step immunological priming, with an elevation of innate immune genes at the primary tumor and full-blown activation of the immune system within the secondary tumor.ConclusionsBlockade of TIGIT and LAG3 with NBTXR3+XRT+aPD1 improved CD8+ T-cell proliferation, augmented the antitumor response at both irradiated and unirradiated (abscopal) tumors, and induced potent long-term antitumor memory in mice.AcknowledgementsThis work was supported by Cancer Center Support (Core) Grant CA016672 to The University of Texas MD Anderson Cancer Center; the Goodwin family research fund; the family of M.

Abstract
Introduction
The gaps in formal education caused by the pandemic have provided medical students with opportunities to redefine their role in settings across clinical medicine, education and research. This task shifting could provide avenues for students to engage with global surgery, where the cultivation of research skills, networking, and global collaboration amongst students is imperative for sustainable progress.
COVIDPaedsCancer is an international collaborative cohort study assessing the impact of the pandemic on paediatric cancer services. We aimed to trial a student and junior doctor-lead team to perform the day-to-day running of this research.
Method
An operations team of 47 students and junior doctors across 11 countries was assembled. Sub-teams were created for social media, network management, email communications, REDCap, research support and graphics. Together, they ran the study under guidance from the steering committee.
Results
To date, the operations team has coordinated study collaborators in collecting data for 1252 patients from 78 centres across 39 countries. Cooperation between sub-teams enabled the recruitment of collaborators from 558 hospitals in total. They also identified 2 errors in the protocol and resolved them with steering committee input, and continuously managed hospital leadership issues and general queries throughout the course of the study. The team was able to adapt in response to the evolving needs of collaborators and the steering committee.
Conclusions
Medical students were able to aid the delivery of an international, multicentre, collaborative, global surgery research study while benefiting from learning opportunities, networking opportunities, and developing interest and understanding of global surgery.

Abstract
PURPOSE Radiation combined with PD1 blockade offers significant treatment benefits in several tumor types; however, anti-PD1 resistance precludes such benefits in many cases. Here we attempted to overcome anti-PD1 resistance by combining localized radiation with a radioenhancing nanoparticle (NBTXR3) and systemic anti-PD1 treatment to achieve abscopal effects in an anti-PD1-resistant mouse model of lung cancer. METHODS AND MATERIALS Female 129Sv/Ev mice were inoculated with 344SQ anti-PD1-resistant (344SQR) or anti-PD1-sensitive (344SQP) metastatic lung cancer cells in the right leg on day 0 ("primary" tumor) and the left leg on day 4 ("secondary" tumor). Primary tumors were injected intratumorally with NBTXR3 on day 7 and were irradiated with 12 Gy on days 8, 9, and 10. Mice were given 6 intraperitoneal injections of anti-PD1. T cell receptor repertoire was analyzed in tumor samples with RNA sequencing, infiltration of CD8 T cells with immunohistochemical staining, and activities of various immune pathways with NanoString analysis. RESULTS The triple combination of NBTXR3 with localized radiation and systemic anti-PD1 significantly delayed the growth of both irradiated and unirradiated tumors in both 344SQP and 344SQR tumor models. NBTXR3 remodeled the immune microenvironment of unirradiated tumors by triggering the activation of various immune pathways, increasing the number of CD8+ T cells, and modifying the T cell receptor repertoire in the 344SQR tumor model. CONCLUSIONS The ability of NBTXR3 to evoke significant abscopal effects in both anti-PD1-sensitive and anti-PD1-resistant lung cancers could open the possibility of its use for treating patients with metastatic lung cancer regardless of sensitivity (or resistance) to immunotherapies.

Abstract
AIM To report early findings from a phase II trial of high-dose radiotherapy (HD-RT) with or without low-dose RT (LD-RT) for metastatic cancer. METHODS Eligible patients had metastatic disease that progressed on immunotherapy within 6 months. Patients were given either HD-RT (20-70 Gy total; 3-12.5 Gy/f), or HD-RT + LD-RT (0.5-2 Gy/f up to 1-10 Gy total) to separate lesions, with continued immunotherapy. Radiographic response was assessed per RECIST 1.1 and Immune-Related Response Criteria (irRC). Primary endpoints: (1) 4-month disease control (DCR, complete/partial response [CR/PR] or stable disease [SD]) or an overall response (ORR, CR/PR) at any point in ≥10% of patients, per RECIST 1.1; (2) dose-limiting toxicity within 3 months not exceeding 30%. Secondary endpoint was lesion-specific response. RESULTS Seventy-four patients (NSCLC, n = 38; melanoma n = 21) were analyzed (39 HD-RT and 35 HD-RT + LD-RT). The median follow-up time was 13.6 months. The primary endpoint was met for 72 evaluable patients, with a 4-month DCR of 42% (47% [16/34] vs. 37% [14/38] in HD-RT + LD-RT vs. HD-RT, P = 0.38), and 19% ORR at any time (26% [9/34] vs. 13% [5/38] in HD-RT + LD-RT vs. HD-RT, P = 0.27). Three patients had toxicity ≥grade 3. LD-RT lesion response (53%) was improved compared to nonirradiated lesions in HD-RT + LD-RT (23%, P = 0.002) and HD-RT (11%, P < 0.001). T- and NK cell infiltration was enhanced in lesions treated with LD-RT. CONCLUSIONS HD-RT plus LD-RT safely improved lesion-specific response in patients with immune resistant solid tumors by promoting infiltration of effector immune cells into the tumor microenvironment.

Abstract
Abstract
Introduction: Despite evidence that a subset of patients with locoregionally advanced non-small cell lung cancer (NSCLC) can be cured with radiation doses less than 60 Gy, there are currently no validated approaches to identify patients that could benefit from radiation dose de-escalation. Normal tissue changes including inflammation and fibrosis can be difficult to distinguish from residual disease on standard imaging during and following chemoradiation therapy (CRT), making assessment of treatment response and identification of favorable responders challenging. We hypothesized that circulating tumor DNA (ctDNA) kinetics during CRT could be used as a surrogate of response to identify genomic predictors of rapid response to treatment. Methods: We applied cancer personalized profiling by deep sequencing (CAPP-Seq) ctDNA analysis to 61 patients treated with CRT for Stage II-III NSCLC. We quantified ctDNA concentrations pre-CRT and a median of 21 days into CRT (mid-CRT) to determine the log-fold change in ctDNA concentration and identify “rapid responders.” The association between ctDNA log-fold change as a continuous variable with progression-free survival (PFS) was analyzed using univariable and multivariable regression, including gender, age, and stage as co-variables. The prevalence of driver gene single nucleotide variants in rapid responders versus slow responders was compared for each gene using Fisher’s exact tests with P-values adjusted using the Benjamini-Hochberg procedure. Results: Mid-CRT ctDNA log-fold change was significantly associated with progression-free survival as a continuous variable on both univariable (P=0.02) and multivariable analysis (P=0.03). Among patients whose ctDNA log-fold change was more negative than -2.15, 10/11 (91%) did not recur within the radiation field. We defined ctDNA rapid responders as the 10 patients with the largest decrease in ctDNA concentration mid-CRT without local progression. Compared with slow responders, ctDNA rapid responders had a trend towards more TP53 mutations (P=0.12), but no driver mutations were significantly enriched in rapid responders. Notably, mutations in common driver genes KEAP1, NFE2L2, KRAS, and EGFR were observed in 36% of slow responders and 0% of rapid responders (P=0.03). Conclusions: Our results suggest that ctDNA kinetics during CRT can identify patients responding favorably to treatment. Additional molecular characterization of ctDNA rapid responders may enable identification of patients who could benefit from treatment de-escalation.

Abstract
Metastatic cancer is a heterogeneous entity, some of which could benefit from local consolidative radiation therapy (RT). Although randomized evidence is growing in support of using RT for oligometastatic disease, a highly active area of investigation relates to whether RT could benefit patients with polymetastatic disease. This article highlights the preclinical and clinical rationale for using RT for polymetastatic disease, proposes an exploratory framework for selecting patients best suited for these types of treatments, and briefly reviews potential challenges. The goal of this hypothesis-generating review is to address personalized multimodality systemic treatment for patients with metastatic cancer. The rationale for using high-dose RT is primarily for local control and immune activation in either oligometastatic or polymetastatic disease. However, the primary application of low-dose RT is to activate distinct antitumor immune pathways and modulate the tumor stroma in efforts to better facilitate T cell infiltration. We explore clinical cases involving high- and low-dose RT to demonstrate the potential efficacy of such treatment. We then group patients by extent of disease burden to implement high- and/or low-dose RT. Patients with low-volume disease may receive high-dose RT to all sites as part of an oligometastatic paradigm. Subjects with high-volume disease (for whom standard of care remains palliative RT only) could be treated with a combination of high-dose RT to a few sites for immune activation, while receiving low-dose RT to several remaining lesions to enhance systemic responses from high-dose RT and immunotherapy. We further discuss how emerging but speculative concepts such as immune function may be integrated into this approach and examine therapies currently under investigation that may help address immune deficiencies. The review concludes by addressing challenges in using RT for polymetastatic disease, such as concerns about treatment planning workflows, treatment times, dose constraints for multiple-isocenter treatments, and economic considerations.

Abstract
OBJECTIVE Although intensity-modulated radiation therapy (IMPT) is dosimetrically superior to passive scattering proton therapy (PSPT) for locally advanced NSCLC (LA-NSCLC), direct comparisons of clinical outcomes are lacking. Here, we compare toxicity profiles and clinical outcomes after IMPT versus PSPT for LA-NSCLC. METHODS This is a nonrandomized, comparative study of two independent cohorts with LA-NSCLC (stage II-IIIB, stage IV with solitary brain metastasis) treated with concurrent chemotherapy and proton beam therapy. Toxicity (Common Terminology Criteria for Adverse Events version 4.0) and outcomes were prospectively collected as part of a clinical trial (ClinicalTrials.gov identifier NCT00915005) or prospective registry (ClinicalTrials.gov identifier NCT00991094). RESULTS Of 139 patients, 86 (62%) received PSPT and 53 (38%) IMPT; median follow-up times were 23.9 and 29.0 months, respectively. IMPT delivered lower mean radiation doses to the lungs (PSPT 16.0 Gy versus IMPT 13.0 Gy, p < 0.001), heart (10.7 Gy versus 6.6 Gy, p = 0.004), and esophagus (27.4 Gy versus 21.8 Gy, p = 0.005). Consequently, the IMPT cohort had lower rates of grade 3 or higher pulmonary (17% versus 2%, p = 0.005) and cardiac (11% versus 0%, p = 0.01) toxicities. Six patients (7%) with PSPT and zero patients (0%) with IMPT experienced grade 4 or 5 toxicity. Lower rates of pulmonary (28% versus 3%, p = 0.006) and cardiac (14% versus 0%, p = 0.05) toxicities were observed in the IMPT cohort even after propensity score matching for baseline imbalances. There was also a trend toward longer median overall survival in the IMPT group (23.9 mo versus 36.2 mo, p = 0.09). No difference was found in the 3-year rates of local (25% versus 20%, p = 0.44), local-regional (29% versus 36%, p = 0.56) and distant (52% versus 51%, p = 0.71) recurrences. CONCLUSIONS IMPT is associated with lower radiation doses to the lung, heart, and esophagus, and lower rates of grade 3 or higher cardiopulmonary toxicity; additional clinical studies will be needed to assess the potential differences in survival between the two techniques.

Abstract
OBJECTIVE To explore caregivers' perspective on factors affecting the recovery of their family members diagnosed with schizophrenia. METHODS A qualitative grounded theory approach was used. A convenience sample of seven male and eleven female family caregivers of patients with schizophrenia were invited from outpatient (n = 6), inpatient (n = 7), and psychiatric rehabilitation (n = 5) services in an Indian mental health institute to participate in semi-structured interviews. Interviews were recorded, transcribed, and analysed. Similar themes were grouped and the main themes identified. RESULTS Caregivers' perspectives on factors affecting recovery from schizophrenia were categorised to two themes: facilitators and barriers. The nine facilitators were (1) getting into a precise treatment regimen and sticking to it, (2) developing some personal attributes, (3) exercising family's role diametrically, (4) paying attention to basic needs, (5) sharing with the Almighty, (6) adapting to a supportive lifestyle, (7) not being idle… engage in something, (8) coming out, being and sharing with others, and (9) having adequate resources with a good support system. The ten barriers were (1) detrimental treatment practices, (2) hampering illness impacts, (3) off-putting personality elements, (4) unaccommodating family circumstances, (5) caregivers' limitation, (6) flaccid support system and scarce resources, (7) ambiguous treatment outcome or prognosis, (8) futile religious, health, and social belief systems, (9) situational factors, and (10) presence of troubling physical or psychological stressors. CONCLUSION The recovery process is facilitated through family involvement and support by mental health professionals. Thus, giving a pre-treatment counselling to the caregivers and repeating the same content to the patients after regaining insight can be helpful.
