Abstract
OBJECTIVE To investigate differences in standard clinico-radiological evaluation versus Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 for reporting survival outcomes in patients with locally advanced cervical cancer treated with chemoradiation and brachytherapy. METHODS Between November 2017 and March 2020, patients recruited in cervical cancer trials were identified. MRI at diagnosis and at least one follow-up imaging was mandatory. Disease-free survival and progression-free survival were determined using standard evaluation (clinical examination and symptom-directed imaging) and RECIST 1.1. Agreement between criteria was estimated using κ value. Sensitivity analysis was done to test the sensitivity, specificity, and accuracy of RECIST 1.1 in detecting response to treatment. RESULTS Sixty-nine eligible patients had at least one target lesion. Thirty-three patients (47.8%) had pathological lymph nodes. Of these 33 patients, RECIST 1.1 classified only 18% (6/33) as 'target nodal lesions' and the remaining nodes as 'non-target'. There were 6 (8.7%) and 8 (11.6%) patients with disease events using RECIST 1.1 and standard evaluation, respectively. The disease-free survival at 12, 18, and 24 months using RECIST 1.1 was 94.2%, 91.2%, 91.2%, and with standard evaluation was 94.2%, 89.7%, and 88.2%, respectively (p=0.58). Whereas, progression-free survival at 12, 18, and 24 months using RECIST 1.1 and standard evaluation were same (94.2%, 91.2%, and 91.2%, respectively). The κ value was 0.84, showing strong agreement in assessing disease-free survival, although an absolute difference of 3% between endpoint assessment methodologies. RECIST 1.1 had a sensitivity of 75% (95% CI 34.91% to 96.81%), specificity of 100% (95% CI 94.13% to 100%), and accuracy of 97.1% (95% CI 89.92% to 99.65%). CONCLUSIONS The study showed 1.5% and 3% difference in disease-free survival at 18 and 24 months and no difference in progression-free survival between RECIST 1.1 and standard evaluation in a patient cohort with low event rate.

Abstract
PURPOSE To evaluate clinical outcomes of CT-based adaptive intracavitary and interstitial brachytherapy (IC followed by IC-ISBT) in locally advanced cervical cancer (LACC) in resource-constrained settings. METHODS AND MATERIALS LACC patients treated with adaptive brachytherapy techniques were analyzed to evaluate treatment characteristics and clinical outcomes. The Kaplan-Meier method was used for survival analysis, and the log-rank test for univariate analysis. RESULTS Out of 141 eligible patients with LACC, 87 (61.7%) patients received external beam radiotherapy (EBRT) in referral hospitals, while 54 (38.3%) were treated at our center. We divided our cohort into two groups: poor EBRT responder group (n = 70 [49.6%]) where IC-ISBT was adapted to achieve optimum tumor doses and OAR optimization group 71 (50.4%) where IC-ISBT was performed to reduce OAR doses. Median HRCTV-D90 dose was 88 Gy (range 70-109 Gy) with median HRCTV volume 33cc (range 15-96). Median D2cc doses to OARs were 90 Gy (range 70-107), 71 Gy (range 55-105) and 70 Gy (range 47-90) to bladder, rectum and sigmoid, respectively. At median follow-up of 32 months, 3-year local control (LC), locoregional control (LRC), disease-free survival (DFS) and overall survival (OS) were 83%, 75%, 64% and 72%, respectively. Subgroup analysis revealed significantly better outcomes for OAR optimization compared to poor EBRT responders, with 3-year LC (95% vs. 70.1%, p < 0.001), LRC (87.3% vs. 62.7%, p < 0.001), DFS (79.2% vs. 49.4%, p < 0.001), and OS (86.2% vs. 57.4%, p < 0.001) CONCLUSION: In resource-constrained settings, implementation of Adaptive IC-ISBT is a viable alternative for optimizing OAR doses in LACC. However proactive approach employing IC-ISBT for tumor dose-escalation from first fraction of BT is warranted for improving LC in poor EBRT responders.

Abstract
Electrophysiology has proven invaluable to record neural activity, and the development of Neuropixels probes dramatically increased the number of recorded neurons. These probes are often implanted acutely, but acute recordings cannot be performed in freely moving animals and the recorded neurons cannot be tracked across days. To study key behaviors such as navigation, learning, and memory formation, the probes must be implanted chronically. An ideal chronic implant should (1) allow stable recordings of neurons for weeks; (2) allow reuse of the probes after explantation; (3) be light enough for use in mice. Here, we present the "Apollo Implant", an open-source and editable device that meets these criteria and accommodates up to two Neuropixels 1.0 or 2.0 probes. The implant comprises a "payload" module which is attached to the probe and is recoverable, and a "docking" module which is cemented to the skull. The design is adjustable, making it easy to change the distance between probes, the angle of insertion, and the depth of insertion. We tested the implant across eight labs in head-fixed mice, freely moving mice, and freely moving rats. The number of neurons recorded across days was stable, even after repeated implantations of the same probe. The Apollo implant provides an inexpensive, lightweight, and flexible solution for reusable chronic Neuropixels recordings.

Abstract
INTRODUCTION India contributes two-thirds of the global mortality due to oral cancer and has a younger population at risk. The societal costs of this premature mortality are barely discussed. METHODS Using the human capital approach, we aimed to estimate the productivity lost due to premature mortality, valued using individual socioeconomic data, related to oral cancer in India. A bottom-up approach was used to prospectively collect data of 100 consecutive patients with oral cancer treated between 2019 and 2020, with a follow-up of 36 months. RESULTS The disease-specific survival for early and advanced stage was 85% and 70%, with a median age of 47 years. With 671 years lost prematurely, the loss of productivity was $41 900/early and $96 044/advanced stage. Based on population level rates, the total cost of premature mortality was $5.6 billion, representing 0.18% of GDP. CONCLUSION India needs to implement tailored strategies to reduce the economic burden from premature mortality.

Abstract
In the present study, a novel environment friendly dry method for preparation of guar gum maleate (GGM) with varying degrees of substitution (DS; 0.02-1.04) was optimized. GGM with a maximum DS of 1.04 was successfully synthesized using guar gum (GG) and maleic anhydride (MA) in proportion of 1: 1 at 80 °C with 4 h of reaction time. The activation energy for the reaction was determined to be 36.91 ± 3.61 kJ mol-1 with pre-exponential factor of 1392 min-1. Esterification of GG was confirmed by FT-IR and 13C NMR. Analysis using size exclusion chromatography (SEC) indicated a decrease in weight average molecular weight (Mw) of the polymer with an increase in polydispersity index (PDI) due to esterification. In comparison with GG, GGM displayed increased hydrophobicity and reduced thermal stability, as analysed by differential scanning calorimetry (DSC). Rheological studies of GGM revealed that initial apparent viscosity decreased with increasing DS. For the first time, the study offered valuable insights on GGM synthesis under dry solvent-less reaction conditions enabling simpler and scalable synthesis process.

Abstract
Eight QSAR models (M1-M8) were developed from a dataset of 118 benzo-fused heteronuclear derivatives targeting VEGFR-2 by Monte Carlo optimization method of CORALSEA 2023 software. Models were generated with hybrid optimal descriptors using both SMILES and Graphs with zero- and first-order Morgan extended connectivity index from a training set of 103 derivatives. All statistical parameters for model validation were within the prescribed limits, establishing the models to be robust and of excellent quality. Among all models, split-2 of M5 was the best-fit as reflected by r v a lidation 2 , Q v a lidation 2 and MAE . Mechanistic interpretation of this model assisted the identification of structural descriptors as promoters and hinderers for VEGFR-2 inhibition. These descriptors were utilized to design novel VEGFR-2 inhibitors (YS01-YS07) by bringing modifications in compound MS90 in the dataset. Docking of all designed compounds, MS90 and sorafenib with VEGFR-2 binding site revealed favourable binding interactions. Docking score of YS07 was higher than that of MS90 and sorafenib. Molecular dynamics simulation study revealed sustained interactions of YS07 with key amino acids of VEGFR-2 at a run time of 100 ns. This study concludes the development of a best fit QSAR model which can assist the design of new anticancer agents targeting VEGFR-2.

Abstract
OBJECTIVES The primary objective of this study was to assess the validity of the KPG index in predicting the difficulty of treatment involving impacted maxillary canines. The secondary objective was to assess the reliability and reproducibility of the index. MATERIALS AND METHODS A retrospective study was conducted on 96 maxillary impacted canines (MIC) in 60 patients aged 13-35 years. Cone-beam computed tomography (CBCT) scans were used to predict the treatment difficulty of MIC using the KPG index. Patient case files were assessed for the actual difficulty encountered in treating MIC. Cohen's kappa correlation coefficient was used for intra-observer reliability and Kendell's W test was used for inter-observer reliability. Spearman's correlation coefficient test was used to assess the correlation between predicted and actual treatment. RESULTS Easy and moderately difficult cases exhibited a moderate correlation between actual and predicted treatment outcomes, whereas difficult cases displayed a weak correlation. The perfect correlation was observed exclusively in extremely difficult cases. The intra-observer reliability for assessing CBCT scans using the KPG guide was found to be 0.88, and the inter-rater reliability was 0.94. CONCLUSION The KPG index displayed 87%, 71%, 50% and 100% validity in easy, moderately difficult, difficult, and extremely difficult cases, respectively. This index showed good reliability and reproducibility. However, it is imperative to consider a multitude of other factors, including the patient's age, presence of associated root resorption in adjacent teeth, and duration of treatment, to make an informed decision between surgical exposure and extraction.

Abstract
BACKGROUND Sacituzumab govitecan (SG) is a Trop-2-directed antibody-drug conjugate containing cytotoxic SN-38, the active metabolite of irinotecan. SG received accelerated US Food and Drug Administration approval for locally advanced (LA) or metastatic urothelial carcinoma (mUC) previously treated with platinum-based chemotherapy and a checkpoint inhibitor, based on cohort 1 of the TROPHY-U-01 study. Mutations in the uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene are associated with increased adverse events (AEs) with irinotecan-based therapies. Whether UGT1A1 status could impact SG toxicity and efficacy remains unclear. PATIENTS AND METHODS TROPHY-U-01 (NCT03547973) is a multicohort, open-label, phase II registrational study. Cohort 1 includes patients with LA or mUC who progressed after platinum- and checkpoint inhibitor-based therapies. SG was administered at 10 mg/kg intravenously on days 1 and 8 of 21-day cycles. The primary endpoint was objective response rate (ORR) per central review; secondary endpoints included progression-free survival, overall survival, and safety. Post hoc safety analyses were exploratory with descriptive statistics. Updated analyses include longer follow-up. RESULTS Cohort 1 included 113 patients. At a median follow-up of 10.5 months, ORR was 28% (95% CI 20.2% to 37.6%). Median progression-free survival and overall survival were 5.4 months (95% CI 3.5-6.9 months) and 10.9 months (95% CI 8.9-13.8 months), respectively. Occurrence of grade ≥3 treatment-related AEs and treatment-related discontinuation were consistent with prior reports. UGT1A1 status was wildtype (∗1|∗1) in 40%, heterozygous (∗1|∗28) in 42%, homozygous (∗28|∗28) in 12%, and missing in 6% of patients. In patients with ∗1|∗1, ∗1|∗28, and ∗28|∗28 genotypes, any grade treatment-related AEs occurred in 93%, 94%, and 100% of patients, respectively, and were managed similarly regardless of UGT1A1 status. CONCLUSIONS With longer follow-up, the ORR remains high in patients with heavily pretreated LA or mUC. Safety data were consistent with the known SG toxicity profile. AE incidence varied across UGT1A1 subgroups; however, discontinuation rates remained relatively low for all groups.

Abstract
INTRODUCTION Ustekinumab use in ulcerative colitis had shown low adverse event and high persistence rates to 3 years via the UNIFI long-term extension study. Outcomes beyond 3 years have not been previously described. We describe the safety signals of the entire UNIFI Australian population beyond 3 years. METHODS This retrospective multicenter observational cohort study recruited from all Australian UNIFI centers. The primary outcome was safety via adverse events. Secondary outcomes included the clinical relapse rate on ustekinumab, and the need to switch from ustekinumab to an alternate agent. RESULTS There were 14 patients [11 male, mean age 47 (±14) years], with a median diagnosis of 10.8 (±4.5) years prior to UNIFI enrollment. Median follow-up was 298 weeks (5.7 years) (Interquartile range (IQR): 220-311 weeks). Within the long-term extension, there were three serious adverse events and one minor event. 42.9% (6/14) patients had clinical relapses, of which clinical remission was recaptured in 83.3% (5/6). 85.7% (12/14) persisted on ustekinumab in the long-term, with 7.1% (1/14) electively ceasing ustekinumab and 7.1% (1/14) changed from ustekinumab due to clinical relapse. CONCLUSION For moderate-to-severe UC in Australia, ustekinumab maintained efficacy beyond 3 years with a high persistence rate and no new safety signals. TRIAL REGISTRATION The trial is registered at ANZCTR (identifier: ACTRN12622001332718).

Abstract
Current strategies to treat pediatric acute lymphoblastic leukemia rely on risk stratification algorithms using categorical data. We investigated whether using continuous variables assigned different weights would improve risk stratification. We developed and validated a multivariable Cox model for relapse-free survival (RFS) using information from 21199 patients. We constructed risk groups by identifying cutoffs of the COG Prognostic Index (PICOG) that maximized discrimination of the predictive model. Patients with higher PICOG have higher predicted relapse risk. The PICOG reliably discriminates patients with low vs. high relapse risk. For those with moderate relapse risk using current COG risk classification, the PICOG identifies subgroups with varying 5-year RFS. Among current COG standard-risk average patients, PICOG identifies low and intermediate risk groups with 96% and 90% RFS, respectively. Similarly, amongst current COG high-risk patients, PICOG identifies four groups ranging from 96% to 66% RFS, providing additional discrimination for future treatment stratification. When coupled with traditional algorithms, the novel PICOG can more accurately risk stratify patients, identifying groups with better outcomes who may benefit from less intensive therapy, and those who have high relapse risk needing innovative approaches for cure.

Abstract
OBJECTIVE The aim of this study was to assess the biodistribution and dosimetry of 177 Lu-DOTA-trastuzumab in patients with HER2-positive breast carcinoma using whole-body (WB) planar imaging at multiple time points. PATIENTS AND METHODS This study was a prospective evaluation of HER2-positive metastatic/locally advanced breast carcinoma patients who underwent gamma camera imaging for dosimetry and biodistribution studies by using 177 Lu-DOTA-trastuzumab. The standard diagnostic dosimetry protocol was followed, which included cold trastuzumab injection followed by in-house produced 177 Lu-DOTA-trastuzumab. Serial WB planar images (anterior and posterior) were obtained on gamma camera after the infusion of 177 Lu-DOTA-trastuzumab at multiple time points. Whole-body and organ regions of interest were drawn, and the numbers of disintegrations were obtained. The mean absorbed doses for the liver, spleen, kidneys, heart, red marrow, and tumor were obtained from OLINDA EXM v2.1.1 and ORIGIN software. RESULTS The study included a cohort of 21 female breast carcinoma patients. Tracer activity ( 177 Lu-DOTA-trastuzumab) was noted in the physiological organs such as the liver, spleen, kidneys, heart, as well as in the tumors. On visual analysis of 177 Lu-DOTA-trastuzumab biodistribution, the liver activity showed gradual clearance over time, and although spleen was comparatively faintly visualized than liver and similarly, kidneys were faintly visualized suggestive of the alternate route of tracer excretion. The maximum number of patients (n = 12) showed 2 components of clearance, namely, fast and slow. The average effective half-life of all the patients (including single and 2 components of clearance) was 106.25 ± 22.14 hours (84.11-128.39 hours). The mean absorbed dose for the liver, spleen, kidneys, heart, whole body, and red marrow was 1.0702 ± 0.731, 1.4114 ± 0.462, 1.4232 ± 0.364, 1.4719 ± 0.602, 0.2412 ± 0.0295, and 0.1485 ± 0.0213 mGy/MBq, respectively, by OLINDA EXM and 0.5741 ± 0.333, 0.8096 ± 0.224, 0.7943 ± 0.235, 1.8971 ± 0.713, and 0.09619 ± 0.0144 for liver, spleen, kidneys, heart and whole body respectively by ORIGIN. The absorbed radiation dose for tumor was 1.94E+2 by OLINDA EXM software and 1.78E+2 by ORIGIN software. In this study, during and after infusion of 177 Lu-DOTA-trastuzumab, no major adverse effects were noted in any patient except 1 patient who had grade 1 nausea and managed conservatively by antiemetic drug. CONCLUSIONS The results of our study demonstrated expected and favorable biodistribution and dosimetry with 177 Lu-DOTA-trastuzumab in HER2-positive breast carcinoma patients. We noticed the mean absorbed dose to the normal organs within the limits of maximum tolerable dose, and also tumor dose was higher than the normal liver dose. Therefore, we conclude that 177 Lu-DOTA-trastuzumab radioimmunotherapy is feasible and a safe treatment option for treating HER2-positive breast carcinoma patients.

Abstract
BACKGROUND Cancer survivors experience a decrement in health-related quality of life (HRQoL) resulting from the disease as well as adverse effects of therapy. We evaluated the HRQoL of cancer patients, stratified by primary cancer site, stage, treatment response and associated adverse events, along with its determinants. METHODS Data were collected from 12,148 patients, sampled from seven purposively chosen leading cancer hospitals in India, to elicit HRQoL using the EuroQol questionnaire comprising of 5-dimensions and 5-levels (EQ-5D-5L). Multiple linear regression was used to determine the association between HRQoL and various socio-demographic as well as clinical characteristics. RESULTS Majority outpatients (78.4%) and inpatients (81.2%) had solid cancers. The disease was found to be more prevalent among outpatients (37.5%) and inpatients (40.5%) aged 45-60 years and females (49.3-58.3%). Most patients were found to be in stage III (40-40.6%) or stage IV (29.4-37.3%) at the time of recruitment. The mean EQ-5D-5 L utility score was significantly higher among outpatients [0.630 (95% CI: 0.623, 0.637)] as compared to inpatients [0.553 (95% CI: 0.539, 0.567)]. The HRQoL decreased with advancing cancer stage among both inpatients and outpatients, respectively [stage IV: (0.516 & 0.557); stage III (0.609 & 0.689); stage II (0.677 & 0.713); stage I (0.638 & 0.748), p value < 0.001]. The outpatients on hormone therapy (B = 0.076) showed significantly better HRQoL in comparison to patients on chemotherapy. However, palliative care (B=-0.137) and surgery (B=-0.110) were found to be associated with significantly with poorer HRQoL paralleled to chemotherapy. The utility scores among outpatients ranged from 0.305 (bone cancer) to 0.782 (Leukemia). Among hospitalized cases, the utility score was lowest for multiple myeloma (0.255) and highest for testicular cancer (0.771). CONCLUSION Older age, lower educational status, chemotherapy, palliative care and surgery, advanced cancer stage and progressive disease were associated with poor HRQoL. Our study findings will be useful in optimising patient care, formulating individualized treatment plan, improving compliance and follow-up.

Abstract
BACKGROUND Survival outcomes for multiple myeloma have improved dramatically since the introduction of novel therapeutic agents. While these drugs are highly effective in improving survival outcomes and quality of life in patients with multiple myeloma, they come at a significant cost. We assessed the cost-effectiveness of bortezomib-based triplet or quadruplet drug regimens in isolation and followed by autologous hematopoietic stem cell transplantation (AHSCT) for the treatment of newly diagnosed multiple myeloma (NDMM) in the Indian context. METHODS A Markov model was developed to assess the health and economic outcomes of novel drug regimens with and without AHSCT for the treatment of NDMM in India. We estimated the lifetime quality-adjusted life-years (QALYs) and costs in each scenario. The incremental cost-effectiveness ratios (ICERs) were computed and compared against the current willingness-to-pay threshold of a one-time per capita gross domestic product of ₹146,890 (US$1,927.70) for India. Parameter uncertainty was assessed through Monte Carlo probabilistic sensitivity analysis. RESULTS Among seven treatment sequences, the VCd (bortezomib, cyclophosphamide, dexamethasone) alone arm has the lowest cost and health benefits as compared to four treatment sequences, namely VTd (bortezomib, thalidomide, dexamethasone) alone, VRd (bortezomib, lenalidomide, dexamethasone) alone, VRd plus AHSCT and DVRd (Daratumumab, bortezomib, lenalidomide, dexamethasone) plus AHSCT. It was found that VTd plus AHSCT and VCd plus AHSCT arms were extendedly dominated (ED) by combination of two alternative treatments. Among the five non-dominated strategies, VRd has a lowest incremental cost of ₹ 2,20,093 (US$2,888) per QALY gained compared to VTd alone followed by VRd plus AHSCT [₹3,14,530 (US$4,128) per QALY gained] in comparison to VRd alone. None of the novel treatment sequences were found to be cost-effective at the current WTP threshold of ₹1,46,890 (US$1,927.7). CONCLUSION At the current WTP threshold of one-time per capita GDP (₹ 146,890) of India, VRd alone and VRd plus AHSCT has 38.1% and 6.9% probability to be cost-effective, respectively. Reduction in current reimbursement rates of novel drugs, namely VRd, lenalidomide, and pomalidomide plus dexamethasone under national insurance program and societal cost of transplant by 50%, would make VRd plus AHSCT and VTd plus AHSCT cost-effective at an incremental cost of ₹40,671 (US$34) and ₹97,639 (US$1,281) per QALY gained, respectively.

Abstract
Background Chemotherapy-induced nausea and vomiting is a common and unpleasant treatment-related side effect reported by cancer patients receiving chemotherapy. Akynzeo® or NEPA (NEtupitant + PAlonosetron) is the first fixed combination of netupitant and palonosetron that targets both critical pathways involved in emesis while providing a convenient, single oral dose therapy. The current study aimed to assess the effectiveness and safety of NEPA in a real-world setting in India. Methodology This was an open-label, multicenter, prospective, single-arm study conducted at six different locations across India. The study included patients of either gender, aged ≥18 years, naive to chemotherapy, scheduled to receive highly or moderately emetogenic chemotherapy (HEC/MEC), and scheduled to receive oral NEPA, as determined by the investigator. Results A total of 360 people were screened and enrolled in the study. HEC was prescribed to 289 (81.64%) patients, while MEC was prescribed to 65 (18.36%) patients. Complete response was achieved in 94.92% of patients during the acute phase, 95.20% during the delayed phase, and 93.22% during the overall phase. During the overall phase, 92.73% and 95.38% of patients on the HEC and MEC regimens, respectively, achieved complete response. Adverse events were reported in 3.88% of patients. Conclusions Oral NEPA was found to be effective in the Indian real-world setting, eliciting a >90% complete response with HEC and MEC regimens across the acute, delayed, and overall phases.

Abstract
End-of-life care (EOLC) exemplifies the joint mission of intensive and palliative care (PC) in their human-centeredness. The explosion of technological advances in medicine must be balanced with the culture of holistic care. Inevitably, it brings together the science and the art of medicine in their full expression. High-quality EOLC in the ICU is grounded in evidence, ethical principles, and professionalism within the framework of the Law. Expert professional statements over the last two decades in India were developed while the law was evolving. Recent landmark Supreme Court judgments have necessitated a review of the clinical pathway for EOLC outlined in the previous statements. Much empirical and interventional evidence has accumulated since the position statement in 2014. This iteration of the joint Indian Society of Critical Care Medicine-Indian Association of Palliative Care (ISCCM-IAPC) Position Statement for EOLC combines contemporary evidence, ethics, and law for decision support by the bedside in Indian ICUs.

Longitudinal Costs of Image-Guided Intensity-Modulated Radiation Therapy Versus Three-Dimensional Conformal Radiation: Lessons From Phase III PARCER Trial for Shaping Resource-Stratified Guidelines in Low- and Middle-Income Countries. JCO Glob Oncol 2024; 10:e2300478.

Abstract
PURPOSE The PARCER trial provided level I evidence for image-guided intensity-modulated radiation therapy (IG-IMRT) in patients with cervical cancer. Further information regarding long-term financial impact is imperative for adoption into the National Cancer Grid of India cervical cancer resource-stratified guidelines. METHODS Patient data from the PARCER trial were analyzed to evaluate the cost implications of transitioning to IG-IMRT. Lacking differences in outcomes between the three-dimensional conformal radiation (3D-CRT) and IG-IMRT, differences in treatment costs, adverse event incidence, and toxicity management costs were examined. The overall financial impact was estimated by adding the treatment costs, toxicity management, and wage loss. This was extrapolated nationally to determine if a transition to IG-IMRT would be feasible for the Indian health care system. RESULTS Of the 300 patients in the PARCER trial, 93 faced grades ≥2 adverse events (3D-CRT = 59, IG-IMRT = 34). Patients in the 3D-CRT and IG-IMRT arms spent an average of 2.39 years and 1.96 years in toxicity, respectively. The average toxicity management and the yearly financial impact per patient were, respectively, 1.50 and 1.44 times higher for 3D-CRT patients compared with IG-IMRT patients. Extrapolation to the national level showed that treatment with 3D-CRT led to a 2.88 times higher cost ratio when compared with treatment with IG-IMRT. CONCLUSION Although the initial costs of IG-IMRT are high, on the basis of longitudinal data, it is financially inefficient to treat with 3D-CRT. Resource-stratified guidelines should include longitudinal health intervention costs rather than solely initial costs for policy decisions to implement advanced radiation technology.

Abstract
PURPOSE The aim of this study was to examine the postoperative outcomes and follow-up QOL of patients after AWR at a level-1 trauma centre in India. METHODS The study cohort included AWR patients treated between January 2011 and July 2022. The Activities Assessment Scale (AAS) was used to measure QOL, and the Ventral Hernia Recurrence Inventory (VHRI) was used to determine the occurrence of recurrence. In patients suspected of having recurrence, thorough clinical examination and relevant imaging were performed to confirm or rule out recurrence. RESULTS Out of 89 patients, 35 patients whose complete perioperative and follow-up data were available were enrolled. The mean age of the patients was 28 (SD, 9) years. The mean defect size was 14. 9 (SD, 7) cm. The mean time from laparotomy to AWR surgery was 21 months. During the postoperative course, 37% of patients developed complications, such as SSI and seroma. The mean follow-up time was 53 (SD, 43) months. Upon comparing procedures involving the mesh placed in the sublay position with procedures involving the mesh placed in other positions, no statistically significant difference in the recurrence rate (one in each group, p = 0.99), surgical complication rate (33% v/s 66%, p = 0.6), or mean AAS QOL score (94.7 v/s 98, p = 0.4) was observed. The specificity of the VHRI for diagnosing recurrence was 79%. CONCLUSION Overall, the recurrence rate was low in these patients despite the presence of large hernia defects. Long-term QOL was not affected by the specific procedure used. Timely planning and execution are more important than the specific repair approach for post-trauma laparotomy ventral hernia.

Abstract
Surgery exposes tumor tissue to severe hypoxia and mechanical stress leading to rapid gene expression changes in the tumor and its microenvironment, which remain poorly characterized. We biopsied tumor and adjacent normal tissue from breast (BRC) (n=81) and head/neck squamous cancer (HNSC) patients (n=10) at the beginning (A), during (B) and end of surgery (C). Tumor/normal RNA from 46/81 breast cancer patients was subjected to mRNA-Seq using Illumina short-read technology, and from nine HNSC patients to whole transcriptome microarray with Illumina BeadArray. Pathways and genes involved in 7 of 10 known cancer hallmarks, namely, tumour promoting inflammation (TNF-A, NFK-B, IL-18 pathways), activation of invasion & migration [(various Extracellular Matrix (ECM) related pathways, cell migration)], sustained proliferative signaling (K-Ras Signaling), evasion of growth suppressors (P53 signaling, regulation of cell death), deregulating cellular energetics (response to lipid, secreted factors, adipogenesis), inducing angiogenesis (hypoxia signaling, myogenesis), and avoiding immune destruction (CTLA4 and PDL1) were significantly deregulated during surgical resection (time-points A vs B vs C). These findings were validated using NanoString assays in independent pre/intra/post-operative breast cancer samples from 48 patients. In a comparison of gene expression data from biopsy (analogous to time-point A) with surgical resection samples (analogous to time-point C) from The Cancer Genome Atlas (TCGA) study, the top deregulated genes were the same as identified in our analysis, in five of the seven studied cancer types. This study suggests that surgical extirpation deregulates the hallmarks of cancer in primary tumors and adjacent normal tissue across different cancers. Implications: Surgery deregulates hallmarks of cancer in human tissue.

Abstract
We report a deep next-generation sequencing analysis of 13 sequentially obtained tumor samples, eight sequentially obtained circulating tumor DNA (ctDNA) samples and three germline DNA samples over the life history of 3 patients with triple-negative breast cancer (TNBC), 2 of whom had germline pathogenic BRCA1 mutation, to unravel tumor evolution. Tumor tissue from all timepoints and germline DNA was subjected to whole-exome sequencing (WES), custom amplicon deep sequencing (30,000X) of a WES-derived somatic mutation panel, and SNP arrays for copy-number variation (CNV), while whole transcriptome sequencing (RNA-seq) was performed only on somatic tumor.There was enrichment of homologous recombination deficiency signature in all tumors and widespread CNV, which remained largely stable over time. Somatic tumor mutation numbers varied between patients and within each patient (range: 70-216, one outlier). There was minimal mutational overlap between patients with TP53 being the sole commonly mutated gene, but there was substantial overlap in sequential samples in each patient. Each patient's tumor contained a founding ("stem") clone at diagnosis, which persisted over time, from which all other clones ("subclone") were derived ("branching evolution"), which contained mutations in well-characterized cancer-related genes like PDGFRB, ARID2, TP53 (Patient_02), TP53, BRAF, BRIP1, CSF3R (Patient_04), and TP53, APC, EZH2 (Patient_07). Including stem and subclones, tumors from all patients were polyclonal at diagnosis and during disease progression. ctDNA recapitulated most tissue-derived stem clonal and subclonal mutations while detecting some additional subclonal mutations. RNA-seq revealed a stable basal-like pattern, with most highly expressed variants belonging to stem clone. SIGNIFICANCE In germline BRCA1 mutated and BRCA wild-type patients, TNBC shows a branching evolutionary pattern of mutations with a single founding clone, are polyclonal throughout their disease course, and have widespread copy-number aberrations. This evolutionary pattern may be associated with treatment resistance or sensitivity and could be therapeutically exploited.

Abstract
BACKGROUND Olanzapine is an effective antiemetic agent but it results in substantial daytime somnolence when administered at the standard dose. Our aim was to compare the efficacy of low-dose versus standard-dose olanzapine after highly emetogenic chemotherapy in patients with solid tumours. METHODS This was a single-centre, open-label, non-inferiority, randomised, controlled, phase 3 trial done in a tertiary care referral centre in India (Tata Memorial Centre, Homi Bhabha National Institute, Mumbai). Patients aged 13-75 years with an Eastern Cooperative Oncology Group performance status of 0-2, who were receiving doxorubicin-cyclophosphamide or high-dose cisplatin for a solid tumour were eligible. Patients were randomly assigned (1:1), with block randomisation (block sizes of 2 or 4) and stratified by sex, age (≥55 or <55 years), and chemotherapy regimen, to receive low-dose (2·5 mg) oral olanzapine or standard-dose (10·0 mg) oral olanzapine daily for 4 days, in combination with a triple antiemetic regimen. Study staff were masked to treatment allocation but patients were aware of their group assignment. The primary endpoint was complete control, defined as no emetic episodes, no rescue medications, and no or mild nausea in the overall phase (0-120 hours), assessed in the modified intention-to-treat (mITT) population (ie, all eligible patients who received protocol-specified treatment, excluding those who had eligibility violations and who withdrew consent after randomisation). Daytime somnolence was the safety endpoint of interest. Non-inferiority was shown if the upper limit of the one-sided 95% CI for the difference in the complete control proportions between the treatment groups excluded the non-inferiority margin of 10%. This study is registered with the Clinical Trial Registry India, CTRI/2021/01/030233, is closed to accrual, and this is the final data analysis. RESULTS Between Feb 9, 2021, and May 30, 2023, 356 patients were pre-screened for eligibility, of whom 275 patients were enrolled and randomly assigned (134 to the 2·5 mg olanzapine group and 141 to the 10·0 mg olanzapine group). 267 patients (132 in the 2·5 mg group and 135 in the 10·0 mg group) were included in the mITT population, of whom 252 (94%) were female, 15 (6%) were male, and 242 (91%) had breast cancer. 59 (45%) of 132 patients in the 2·5 mg olanzapine group had complete control in the overall phase versus 59 (44%) of 135 in the 10·0 mg olanzapine group (difference -1·0% [one-sided 95% CI -100·0 to 9·0]; p=0·87). In the overall phase, there were significantly fewer patients in the 2·5 mg olanzapine group than in the 10·0 mg olanzapine group with daytime somnolence of any grade (86 [65%] of 132 vs 121 [90%] of 135; p<0·0001) and of severe grade on day 1 (six]5%] vs 54 [40%]; p<0·0001). INTERPRETATION Our findings suggest that olanzapine 2·5 mg is non-inferior to 10·0 mg in antiemetic efficacy and results in reduced occurrence of daytime somnolence among patients receiving highly emetic chemotherapy and should be considered as a new standard of care.

Abstract
BACKGROUND Fibroblast growth factor receptor 3 (FGFR3) alterations are oncogenic drivers of urothelial carcinoma (UC). Pemigatinib is a selective, oral inhibitor of FGFR1-3 with antitumor activity. We report the efficacy and safety of pemigatinib in the open-label, single-arm, phase II study of previously treated, unresectable or metastatic UC with FGFR3 alterations (FIGHT-201; NCT02872714). PATIENTS AND METHODS Patients ≥18 years old with FGFR3 mutations or fusions/rearrangements (cohort A) and other FGF/FGFR alterations (cohort B) were included. Patients received pemigatinib 13.5 mg once daily continuously (CD) or intermittently (ID) until disease progression or unacceptable toxicity. The primary endpoint was centrally confirmed objective response rate (ORR) as per RECIST v1.1 in cohort A-CD. Secondary endpoints included ORR in cohorts A-ID and B, duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS Overall, 260 patients were enrolled and treated (A-CD, n = 101; A-ID, n = 103; B, n = 44; unconfirmed FGF/FGFR status, n = 12). All discontinued treatment, most commonly due to progressive disease (68.5%). ORR [95% confidence interval (CI)] in cohorts A-CD and A-ID was 17.8% (10.9% to 26.7%) and 23.3% (15.5% to 32.7%), respectively. Among patients with the most common FGFR3 mutation (S249C; n = 107), ORR was similar between cohorts (A-CD, 23.9%; A-ID, 24.6%). In cohorts A-CD/A-ID, median (95% CI) DOR was 6.2 (4.1-8.3)/6.2 (4.6-8.0) months, PFS was 4.0 (3.5-4.2)/4.3 (3.9-6.1) months, and OS was 6.8 (5.3-9.1)/8.9 (7.5-15.2) months. Pemigatinib had limited clinical activity among patients in cohort B. Of 36 patients with samples available at progression, 6 patients had 8 acquired FGFR3 secondary resistance mutations (V555M/L, n = 3; V553M, n = 1; N540K/S, n = 2; M528I, n = 2). The most common treatment-emergent adverse events overall were diarrhea (44.6%) and alopecia, stomatitis, and hyperphosphatemia (42.7% each). CONCLUSIONS Pemigatinib was generally well tolerated and demonstrated clinical activity in previously treated, unresectable or metastatic UC with FGFR3 mutations or fusions/rearrangements.

Abstract
PURPOSE To optimize real-time PCR assays for diagnosis of Bacterial Vaginosis (BV) and determine cut-off loads by ROC analysis for Gardnerella vaginalis, Atopobium vaginae and Lactobacillus spp. as compared to Nugent scoring (Gold standard) in clinical samples. RESULTS Out of 125 women, 34 were positive, 26 intermediate and 65 negative for BV by Nugent scoring. All three real-time PCR assays were found to be highly sensitive & specific and AUC suggested excellent diagnostic accuracy. An optimal cut-off was >9.45 × 103 copies/ ml, >3.34 × 103 copies/ ml & ≤ 18.63 × 103 copies/ ml for G. vaginalis, A. vaginae and Lactobacillus spp. respectively, in BV positives. Gram staining and qPCR were discordant only in patients with intermediate scores (n = 26) where qPCR identified 15 (57.69%) as positive and 11 (42.3%) as negative. CONCLUSION PCR-based molecular BV diagnosis is more accurate and can be used for deciphering intermediate Nugent scores.

Abstract
Obstetric anaesthesiologists play a pivotal role as peripartum physicians steering the team of obstetric healthcare providers towards a continuum of medical education, enhanced training and safer patient care. However, in resource-limited countries, deficiency of human resources and hence services available poses challenges to those attempting to reduce maternal mortality rates. Measures to fill the gap include creating a cadre of uniformly well-trained and certified non-physician anaesthesia providers (NPAPs) supervised by a physician obstetric anaesthesiologist and well-equipped rural and urban health care facilities. The Association of Obstetric Anaesthesiologists of India needs to upscale their outreach programs with regular knowledge updates and practical skill training to the NPAPs, medical graduates and postgraduate doctors in these regions. A combination of strong local administrative will, legislation for the provision of essential supplies and a global collaborative effort using checklists and protocols may help to stem gaps in the provision of safe maternal care.

Abstract
BACKGROUND Bacterial vaginosis (BV) is a common clinical manifestation of a perturbed vaginal ecology associated with adverse sexual and reproductive health outcomes if left untreated. The existing diagnostic modalities are either cumbersome or require skilled expertise, warranting alternate tests. Application of machine-learning tools to heterogeneous and high-dimensional multi-omics datasets finds promising potential in data integration and may aid biomarker discovery. OBJECTIVES The present study aimed to evaluate the potential of the microbiome and metabolome-derived biomarkers in BV diagnosis. Interpretable machine-learning algorithms were used to evaluate the utility of an integrated-omics-derived classification model. METHODS Vaginal samples obtained from reproductive-age group women with (n = 40) and without BV (n = 40) were subjected to 16S rRNA amplicon sequencing and LC-MS-based metabolomics. The vaginal microbiome and metabolome were characterized, and machine-learning analysis was performed to build a classification model using biomarkers with the highest diagnostic accuracy. RESULTS Microbiome-based diagnostic model exhibited a ROC-AUC (10-fold CV) of 0.84 ± 0.21 and accuracy of 0.79 ± 0.18, and important features were Aerococcus spp., Mycoplasma hominis, Sneathia spp., Lactobacillus spp., Prevotella spp., Gardnerella spp. and Fannyhessea vaginae. The metabolome-derived model displayed superior performance with a ROC-AUC of 0.97 ± 0.07 and an accuracy of 0.92 ± 0.08. Beta-leucine, methylimidazole acetaldehyde, dimethylethanolamine, L-arginine and beta cortol were among key predictive metabolites for BV. A predictive model combining both microbial and metabolite features exhibited a high ROC-AUC of 0.97 ± 0.07 and accuracy of 0.94 ± 0.08 with diagnostic performance only slightly superior to the metabolite-based model. CONCLUSION Application of machine-learning tools to multi-omics datasets aid biomarker discovery with high predictive performance. Metabolome-derived classification models were observed to have superior diagnostic performance in predicting BV than microbiome-based biomarkers.

Abstract
PURPOSE The treatment outcomes of adolescent and young adult (AYA) cancers have improved with advanced oncology care. Hence, fertility preservation (FP) and post-therapy pregnancies (PTPs) become vital issues. MATERIALS AND METHODS An online survey link with 17 questions regarding oncofertility and PTPs was circulated among oncologists to assess the knowledge, understand the oncofertility care patterns, and seek suggestions to improve oncofertility services. RESULTS The median age of 179 respondents, predominantly medical oncologists (68.7%), was 37 years (IQR, 10; range, 29-74), working in academic centers (39%) having a median experience of 4 years (IQR, 4; range, 1-42); 23 (12.8%) had dedicated AYA cancer units. Although a quarter (19%-24%) of respondents discussed fertility issues in >90% of AYA patients with cancer, only a tenth (8%-11%) refer >90% for FP, with significantly higher (P < .05) discussions and referrals in males and by more experienced oncologists (P < .05). Forty-six (25.6%) were not well versed with international guidelines for FP. Most (122, 68.1%) oncologists knew about the referral path for semen cryopreservation; however, only 46% were knowledgeable about additional complex procedures. One hundred and ten (61.5%) oncologists never or rarely altered the systemic treatment for FP. Prominent barriers to FP were ignorance, lack of collaboration, and fear of delaying cancer treatment. Lead thrust areas identified to improve FP practices are education, and enhanced and affordable access to FP facilities. Seventy-four (41.3%) respondents knew about international guidelines for PTPs; however, only half (20%) of them often monitored fertility outcomes in survivors. Oncologists have conflicting opinions and uncertainties regarding pregnancy safety, assisted reproductive techniques, breastfeeding, and pregnancy outcomes among survivors. CONCLUSION Oncologists are uncertain about the guidelines, FP practices, referral pathways, and PTPs. Multipronged approaches to improve awareness and provision for affordable oncofertility facilities are needed to enhance AYA cancer outcomes in India, which will be applicable to other low- and middle-income countries too.

Abstract
ABSTRACT The incidence of breast cancer is increasing rapidly in urban India due to the changing lifestyle and exposure to risk factors. Diagnosis at an advanced stage and in younger women are the most concerning issues of breast cancer in India. Lack of awareness and social taboos related to cancer diagnosis make women feel hesitant to seek timely medical advice. As almost half of women develop breast cancer at an age younger than 50 years, breast cancer diagnosis poses a huge financial burden on the household and impacts the entire family. Moreover, inaccessibility, unaffordability, and high out-of-pocket expenditure make this situation grimmer. Women find it difficult to get quality cancer care closer to their homes and end up traveling long distances for seeking treatment. Significant differences in the cancer epidemiology compared to the west make the adoption of western breast cancer management guidelines challenging for Indian women. In this article, we intend to provide a comprehensive review of the management of breast cancer from diagnosis to treatment for both early and advanced stages from the perspective of low-middle-income countries. Starting with a brief introduction to epidemiology and guidelines for diagnostic modalities (imaging and pathology), treatment has been discussed for early breast cancer (EBC), locally advanced, and MBC. In-depth information on loco-regional and systemic therapy has been provided focusing on standard treatment protocols as well as scenarios where treatment can be de-escalated or escalated.

Abstract
Identification is one of the most important aspects of mass disasters. Stature estimation is an essential parameter for identification and is widely used in forensic anthropology, where DNA facility is limited. A hand is most studied part of the upper limb; however, data are scarce concerning particular geographical populations. This study is an effort to provide tangible data for such forensic investigations. It was a prospective, cross-sectional study on 500 medicolegal death cases brought for post-mortem examination. It aimed to estimate stature in the Northwest population using hand and finger measurements of dead persons by mathematical models. A total of seven parameters in hand were used to generate linear and multiple regression equations, correlation coefficients and finger indexes for stature estimation and sex differentiation. The correlation coefficient between stature and all the hand measurements were significant except for the index and middle finger on both sides in females. Bilateral differences were insignificant for hand length and breath, except for the middle finger length in both sexes and length of thumb in females. Multiple regression equations for stature estimation were better than linear regression equations for stature estimation. SEE ranged from 4.31 to 6.26 in males and 4.11 to 5.25 in females. For identification, hand length is the best individual parameter among other hand measurements. The measurement accuracy and practical aspects can be enhanced if we consider cadaveric participants. The multiple regression model approach can give a fair estimate of the stature of the deceased.

Abstract
PURPOSE Variations in the levels of systemic inflammatory biomarker levels have been linked with outcomes in various malignancies including cervical cancer. In this study, we investigated prognostic implications of pretreatment hematological factors/indices in locally advanced cervical cancers treated with radical radio(chemo)therapy. METHODS AND MATERIALS Electronic medical records of 1051 patients with cervical cancer of FIGO (International Federation of Gynecology and Obstetrics) stage IB2-IVA treated in various prospective trials at our institute between 2003 and 2017 were reviewed. All clinical parameters such as age (dichotomized at the median), stage (IB2-IIB vs III-IVA), histologic type (squamous vs others), and hematological parameters (hemoglobin, platelets, absolute neutrophil count, absolute lymphocyte count, absolute monocyte count) were recorded. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and prognostic nutritional index (PNI; defined as 10 × albumin concentration [g/dL] + 0.005 × total lymphocyte count [μL]) were calculated. Univariate and multivariate (Cox regression) analyses were performed to evaluate these factors with disease-free survival (DFS) and overall survival (OS). RESULTS With a median follow-up of 69 months, the 5-year DFS and OS were 65% and 69%, respectively. On multivariate analysis, FIGO stage (hazard ratio [HR], 1.9; P = .000) and PLR (HR, 1.002; P = .008) significantly affected DFS while FIGO stage (HR, 1.804; P = .000), LMR (HR, 0.92; P = .018), PNI (HR, 0.96; P = .013), and PLR (HR, 1.002; P = .006) significantly affected OS. Apart from FIGO stage, PLR significantly affected both DFS and OS. This correlation of hematological parameters is stronger in stage IIIB cervical cancer. CONCLUSIONS Hematological indices, including PNI, PLR, and LMR, can serve as reliable prognostic indicators for patients with cervical cancer. By incorporating these indices into routine assessment and monitoring, clinicians can better stratify patients, personalize treatment plans, and more accurately predict outcomes, ultimately improving patient care and management.

Abstract
OBJECTIVES The presence of dental anomalies could play a significant role in the identification of individuals by comparing antemortem and postmortem data. This cross-sectional study aimed to assess the level of knowledge, attitude, and awareness among dental professionals regarding the importance of charting dental anomalies and maintaining dental records. METHODOLOGY A self-structured questionnaire was e-mailed to dental professionals practicing in India. The responses were recorded, data tabulated, and one-way ANOVA and post hoc tests were applied for analysis. The criterion for significance was p < .05. RESULTS A total of 406 dental professionals responded to the survey. A significant difference was observed in the mean attitude score of participants towards the importance of charting dental anomalies and maintaining dental records with regard to place of work (p=.001), gender (p=.044) and educational qualification (p=.039). In addition, a statistically significant difference was observed in the mean awareness score of participants with respect to place of work (p=.033) and gender (p=.001). The major barriers in maintaining dental records were lack of time, adequate knowledge, infrastructure, and financial constraints. CONCLUSION 81.3% and 69.26% study participants had very good awareness and attitude, whereas 71.2% had good knowledge regarding the importance of charting dental anomalies and maintenance of dental records; however, their inaccurate responses in anomaly identification hinted towards the need for proper dental charting and their maintenance to be taught en masse and made part of the BDS curriculum.

Abstract
The JAVELIN Bladder 100 phase III trial led to the incorporation of avelumab first-line (1L) maintenance treatment into international guidelines as a standard of care for patients with advanced urothelial carcinoma (UC) without progression after 1L platinum-based chemotherapy. JAVELIN Bladder 100 showed that avelumab 1L maintenance significantly prolonged overall survival (OS) and progression-free survival in this population compared with a 'watch-and-wait' approach. The aim of this manuscript is to review clinical studies of avelumab 1L maintenance in patients with advanced UC, including long-term efficacy and safety data from JAVELIN Bladder 100, subgroup analyses in clinically relevant subpopulations, and 'real-world' data obtained outside of clinical trials, providing a comprehensive resource to support patient management. Extended follow-up from JAVELIN Bladder 100 has shown that avelumab provides a long-term efficacy benefit, with a median OS of 23.8 months measured from start of maintenance treatment, and 29.7 months measured from start of 1L chemotherapy. Longer OS was observed across subgroups, including patients who received 1L cisplatin + gemcitabine, patients who received four or six cycles of 1L chemotherapy, and patients with complete response, partial response, or stable disease as best response to 1L induction chemotherapy. No new safety signals were seen in patients who received ≥1 year of avelumab treatment, and toxicity was similar in those who had received cisplatin or carboplatin with gemcitabine. Other clinical datasets, including noninterventional studies conducted in Europe, USA, and Asia, have confirmed the efficacy of avelumab 1L maintenance. Potential subsequent treatment options after avelumab maintenance include antibody-drug conjugates (enfortumab vedotin or sacituzumab govitecan), erdafitinib in biomarker-selected patients, platinum rechallenge in suitable patients, nonplatinum chemotherapy, and clinical trial participation; however, evidence to determine optimal treatment sequences is needed. Ongoing trials of avelumab-based combination regimens as maintenance treatment have the potential to evolve the treatment landscape for patients with advanced UC.

Abstract
Low-grade serous carcinoma (LGSC) is a rare histologic subtype of ovarian cancer. We present detailed management of 15 cases of advanced LGSC from a tertiary cancer center of India. Fifteen cases of advanced LGSC who underwent cytoreductive surgery (CRS) were analyzed from a prospectively maintained database. Baseline demographic characteristics, surgical details, and chemotherapy details were recorded. Descriptive statistics were summarized, and progression-free survival (PFS) and overall survival (OS) were estimated. The median age was 37 years. Nine patients had received NACT. All cases were FIGO stage III. Mean PCI was 15. Eleven patients had a completeness of cytoreduction score of 0-1. The median surgical time was 7.5 h; nine patients required multiple gastrointestinal resections. Median blood loss was 2500 ml. Median postoperative ventilation, ICU stay, and hospital stays were 1, 2, and 16 days, respectively. One patient had a grade III complication. Four patients received adjuvant chemotherapy. There was no postoperative mortality at the end of 90 days of surgery. All the patients except one were offered hormonal maintenance therapy. At a median follow-up of 43 months, 4 patients were disease-free, 9 had a recurrence, one died of disease progression, and one was lost to follow-up. Most recurrences were locoregional in the peritoneal cavity or pelvis. Four-year OS and PFS were 71.8% and 29.7%, respectively. Advanced LGSCs occur mostly in young premenopausal women with favorable oncologic outcomes. Optimal CRS is the mainstay of treatment. Relative chemo-resistance and hormone receptor positivity provide an excellent therapeutic opportunity for endocrine therapy.

Abstract
OBJECTIVES To evaluate gender differences in workplace violence (WPV) against physicians and nurses in Latin America. STUDY DESIGN Cross-sectional study. METHODS A cross-sectional electronic survey was conducted between January 11 and February 28, 2022. A prespecified gender analysis was performed. RESULTS Among the 3056 responses to the electronic survey, 57% were women, 81.6% were physicians, and 18.4% were nurses. At least one act of violence was experienced by 59.2% of respondents, with verbal violence being the most common (97.5%). Women experienced more WPV than men (65.8% vs 50.4%; P < 0.001; odds ratio [OR]: 1.89; 95% confidence interval [CI]: 1.63-2.19). Women were more likely to report at least one episode of WPV per week (19.2% vs 11.9%, P < 0.001), to request for psychological help (14.5% vs 9%, P = 0.001) and to experience more psychosomatic symptoms. In addition, women were more likely to report having considered changing their job after an aggression (57.6% vs 51.3%, P = 0.011) and even leaving their job (33% vs 25.7%, P = 0.001). In a multivariate analysis, being a woman (OR: 1.76), working in emergency departments (OR: 1.99), and with COVID-19 patients (OR: 3.3) were independently associated with more aggressive interactions, while older age (OR: 0.95) and working in a private setting (OR: 0.62) implied lower risk. CONCLUSIONS Women are more likely to experience WPV and to report more psychosomatic symptoms after the event. Preventive measures are urgently needed, with a special focus on high-risk groups such as women.

Abstract
microRNAs direct regulation of various metabolic pathways in plants and animals. miRNAs may be useful in developing novel/elite genotypes, with enhanced metabolites and disease resistance. We examined miRNAs in tomato. In tomato, miRNAs in the carotenoid pathway have not been fully elucidated. We examined the potential role of miRNAs in biosynthesis of carotenoids, transcript profiling of miRNAs and their possible targets (genes and transcription factors) at different development stages of tomato using stem-loop PCR and RT-qPCR. We also identified miRNAs targeting key flavonoid genes, such as chalcone isomerase (CHI), and dihydroflavonol-4-reductase (DFR). Distinct expression profiles of miRNAs and their targets were found in fruits of three tomato accessions, suggesting carotenoid regulation by miRNAs at various stages of fruit development. This was also confirmed using HPLC of the carotenoids. The present study may help in understanding possible regulation of carotenoid biosynthesis. The identified miRNAs can be exploited to enhance biosynthesis of different carotenoids in plants.

Abstract
PURPOSE To report comorbidity burden in newly-diagnosed treatment-naïve breast cancer patients and its effect on survival. METHODS Prospective observational study in which demographic, comorbidity and outcome data from a consecutive cohort of patients diagnosed and treated between September 2019 to September 2021 were collected. Charlson Comorbidity Index (CCI) score was calculated for all and proportion of each comorbidity was determined at diagnosis (baseline), at conclusion and six-months post-treatment. Univariate and multivariate analysis was done for impact of various demographic and disease-related factors on the incidence of comorbidities as well as on progression free survival (PFS) and overall survival (OS). RESULTS Out of five hundred patients who consented for the study, 416 patients completed planned treatment and only 206 patients had physical follow-up due to COVID-19 pandemic. Incidence of comorbidity at the three time-points was 24%, 32% and 26% respectively. The difference was significant compared to baseline at both the time-points (p<0.05). Hypertension and diabetes were the most common types (incidence 15%-21% and 12-18% respectively) of comorbidities. Advancing age, post-menopauusal status and not being married were significant factors for presence of comorbidities. Median follow-up was 27 months (95% CI 26.25-28.55 months). Presence of multiple comorbidities was a poor prognostic factor for both PFS (2-yr PFS 85% vs 77%) and OS (2-yr OS 89% vs 79%) (both p=0.04) but no such correlation for CCI score. CONCLUSION Breast cancer treatment impacted incidence of comorbidities. Presence of multiple comorbidities had an adverse impact on survival. Hence, further research on treatment optimization is required in patients with substantial comorbidities.

Abstract
PURPOSE To evaluate clinical outcomes of recurrent gynaecological cancers treated with reirradiation (reRT) using advanced brachytherapy (BT) technique. METHODS AND MATERIALS Seventy-six women who underwent reRT with BT for gynaecological cancers at our institute between January 2000 and December 2019 were analysed to determine patient, disease and treatment characteristics and clinical outcomes. Descriptive analysis was used for demographics, and the Kaplan Meir method was used for survival analysis. RESULTS Median age at recurrence was 55 years (Range: 35-73). Forty-three patients had recurrent cervical cancer with intact uterus, and 33 had recurrent vault/vaginal cancers post adjuvant RT. Eight patients received EBRT prior to BT (Range: 30-50Gy). Twenty-two patients (28.9%) received salvage chemotherapy before consideration of brachytherapy. Brachytherapy application was done using MUPIT in 38, Vienna applicator in 20, Syed Neblett in 8, central vaginal cylinder in 3, multicatheter intravaginal applicator in 2, tandem-ovoids in 4 and Houdek applicator in 1 patient. Median cumulative EQD2 for all courses of radiation was 108 Gy (IQR 92-123 Gy). At median follow up of 39 months, local control (LC), progression-free survival (PFS) and Overall survival (OS) at 2-years was 60%, 56.3%, and 72.9 respectively. Patients who had recurrences beyond 2 years had significantly better OS compared to early recurrences. Patients who received BT doses >40 Gy had a higher LC and PFS. Grade 3 to 4 late rectal toxicity was seen in 10 (13%), bladder toxicity in 6 (8%) and vaginal fibrosis in 24 (31%) patients. CONCLUSION The use of advanced BT approach in reirradiation setting is a feasible and safe option in treatment of post-treatment recurrent cervical, endometrial, and vaginal cancers.

Abstract
Tobacco smoking is associated with a substantially increased risk of postoperative complications. The peri-operative period offers a unique opportunity to support patients to stop tobacco smoking, avoid complications and improve long-term health. This systematic review provides an up-to-date summary of the evidence for tobacco cessation interventions in surgical patients. We conducted a systematic search of randomised controlled trials of tobacco cessation interventions in the peri-operative period. Quantitative synthesis of the abstinence outcomes data was by random-effects meta-analysis. The primary outcome of the meta-analysis was abstinence at the time of surgery, and the secondary outcome was abstinence at 12 months. Thirty-eight studies are included in the review (7310 randomised participants) and 26 studies are included in the meta-analysis (5969 randomised participants). Studies were pooled for subgroup analysis in two ways: by the timing of intervention delivery within the peri-operative period and by the intensity of the intervention protocol. We judged the quality of evidence as moderate, reflecting the degree of heterogeneity and the high risk of bias. Overall, peri-operative tobacco cessation interventions increased successful abstinence both at the time of surgery, risk ratio (95%CI) 1.48 (1.20-1.83), number needed to treat 7; and 12 months after surgery, risk ratio (95%CI) 1.62 (1.29-2.03), number needed to treat 9. More work is needed to inform the design and optimal delivery of interventions that are acceptable to patients and that can be incorporated into contemporary elective and urgent surgical pathways. Future trials should use standardised outcome measures.

Abstract
Importance Patients with early breast cancer must choose between undergoing breast conservation surgery or mastectomy. This decision is often difficult as there are trade-offs between breast conservation and adverse effects, and women with higher decisional conflict have a harder time choosing the therapy that suits their preferences. Objective To study the impact of a decision aid with a patient preference assessment tool for surgical decision-making on patients' decisional conflict scale (DCS) score. Design, Setting, and Participants This 3-group randomized clinical trial was conducted between June 2017 and December 2019 at a single high-volume tertiary care cancer center in Mumbai, India. A research questionnaire comprising 16 questions answered on a Likert scale (from 1, strongly agree, to 5, strongly disagree) was used to measure DCS scores and other secondary psychological variables, with higher scores indicating more decisional conflict. The Navya Patient Preference Tool (Navya-PPT) was developed as a survey-based presentation of evidence in an adaptive, conjoint analysis-based module for and trade-offs between cosmesis, adverse effects of radiotherapy, and cost of mandatory radiation following breast-conserving surgery. Adult patients with histologically proven early breast cancer (cT1-2, N0-1) who were eligible for breast-conserving surgery as per clinicoradiological assessment were included. Those who were pregnant or unable to read the research questionnaire or who had bilateral breast cancer were excluded. Data were analyzed from January to June 2020. Interventions Patients were randomized 1:1:1 to study groups: standard care including clinical explanation about surgery (control), standard care plus the Navya-PPT provided to the patient alone (solo group), and standard care plus the Navya-PPT provided to the patient and a caregiver (joint group). Main Outcomes and Measures The primary end point of the study was DCS score. The study was 80% powered with 2-sided α = .01 to detect an effect size of 0.25 measured by Cohen d, F test analysis of variance, and fixed effects. Results A total of 245 female patients (median [range] age, 48 [23-76] years) were randomized (82 to control, 83 to the solo group, and 80 to the joint group). The median (range) pathological tumor size was 2.5 (0-6) cm. A total of 153 participants (62.4%) had pN0 disease, 185 (75.5%) were hormone receptor positive, 197 (80.4%) were human epidermal growth factor receptor 2 negative, 144 (58.6%) were of middle or lower socioeconomic status, and 114 (46.5%) had an education level lower than a college degree. DCS score was significantly reduced in the solo group compared with control (1.34 vs 1.66, respectively; Cohen d, 0.50; SD, 0.31; P < .001) and the joint group compared with control (1.31 vs 1.66, respectively; Cohen d, 0.54; SD, 0.31; P < .001). Conclusions and Relevance The results of this study demonstrated lower decisional conflict as measured by DCS score following use of the online, self-administered Navya-PPT among patients with early breast cancer choosing between breast-conserving surgery vs mastectomy.

Abstract
Several defining molecular alterations have recently been identified underlying high-grade endometrial stromal sarcomas, such as YWHAE: NUTM2A/B fusions, ZC3H7B: BCOR fusions, and BCOR internal tandem duplication (ITD). BCOR is a useful immunohistochemical marker for identifying these tumors. A 37-year-old lady was presented with a 10-cm-sized tumor in the pouch of Douglas, involving the vaginal vault, bilateral adnexa, and peritoneum. A 53-year-old lady with a prior hysterectomy was presented with a 12-cm-sized tumor in the vault with abdominal deposits. Histopathological examination of both tumors revealed atypical cells comprising oval to spindle-shaped nuclei, a variable amount of myxoid stroma, and mitotic figures exceeding 10/10 high power fields. Immunohistochemically, the former tumor was diffusely positive for CD10, and the second tumor displayed patchy staining. Both tumors were positive for BCOR. Estrogen receptor (ER) showed variable staining in both tumors. By fluorescence in-situ hybridization (FISH), both tumors lacked YWHAE gene rearrangement. Both tumors had an aggressive clinical course, including extensive involvement This constitutes the first report of BCOR-positive high-grade sarcomas involving the female genital tract from our subcontinent. BCOR is a useful immunostain for identifying these relatively aggressive tumors. The differential diagnoses and the prognosis of these ultra-rare tumors are discussed herewith.

Abstract
PURPOSE/OBJECTIVE(S) Prospective data have shown that metastasis-directed therapy (MDT) can alter the natural history of oligometastatic disease. In hormone-sensitive prostate cancer (HSPC), the clinical effect of MDT has been validated by STOMP, ORIOLE and SABR-COMET phase II trials. Circulating tumor cells (CTCs) are likely the source for the formation of macroscopic metastases. CTCs may provide an approach for identifying subgroups of patients with oligometastatic HSPC (oligoHSPC) that would benefit most from MDT. Our main goal was to evaluate the feasibility of CTC detection and subtypes in oligoHSPC patients that may benefit from MDT. MATERIALS/METHODS ORIOLE randomized men with recurrent HSPC with 1-3 metastases to observation (Obs) vs. stereotactic ablative radiotherapy (SABR) MDT. Blood samples were prospectively collected at baseline (D0) and 6-mos (D180) and shipped for analysis on Epic Sciences liquid biopsy platform (Epic Sciences, San Diego, CA). Machine learning algorithms identified CTCs and characterized androgen receptor (AR) and PSMA expression. Association with clinical factors and outcomes were examined. Biochemical failure-free survival (BFFS) event was a PSA rise of at least 2 ng/mL and 25% above nadir. Progression-free survival (PFS) was a composite endpoint including BFFS event, radiologic progression (RECIST v1.1); symptomatic progression; initiation of ADT; or death. Comparisons of patient and tumor characteristics performed by two-sample t-tests. Survival curves were generated by the Kaplan-Meier method and evaluated by the log-rank test. Effect of SABR on post-SABR on CTC levels were calculated by McNemar test. RESULTS A total of 82 samples were collected in ORIOLE: 70 SABR (35 D0 and 35 D180) and 12 Obs (7 D0 and 5 D180). 30/42 men had CTCs detected on D0 (71%; AR+ = 7, PSMA+ = 13) and in 26/40 on D180 (65%; AR+ = 9, PSMA+ = 8). Median follow-up was 41.7-mos. There was no association between CTC presence or subtypes (AR+ or PSMA+) with Gleason score or PSA. PFS was significantly lower in the patients with AR+ vs. AR- CTCs on D0 in the SABR arm (p = 0.011, median PFS: AR+ = 9.3- vs. AR+ = 27.1-mos). The median BFFS trended towards a difference for AR+ = 12.9- vs. AR- = 29.2-mos (D180, p = 0.058). SABR had no effect on the presence or subtypes of CTC at D180. CONCLUSION Baseline and dynamic CTC levels and their subtypes in oligoHSPC from the ORIOLE randomized trial of MDT was examined. AR+ CTCs at baseline and 6-mos were correlated with clinical outcomes following SABR. Longer follow-up, further analysis and a greater number of patients are needed for a more comprehensive conclusion.

Abstract
PURPOSE/OBJECTIVE(S) There has been a paradigm shift in managing multiple brain metastases. Various options include SRS, WBRT, and WBRT with Hippocampal avoidance (HA-WBRT). There is no consensus for the treatment of multiple brain metastases (>3 brain metastases). A new technique that has proven feasible is dose escalation in the form of simultaneous integrated boost. The aim of this study was to compare the dosimetry parameters of HA-WBRT plus simultaneous integrated boost versus HA-WBRT alone in multiple brain metastases. MATERIALS/METHODS In a prospective trial,16 patients with multiple brain metastasis (≥ 3) from various primaries with good performance scores (ECOG PS ≤ 2) are recruited. All patients underwent CT simulation (1.5 mm slice thickness) and RT plans for HA-WBRT with (SIB) and HA-WBRT alone were made. A 5 mm margin was given to the bilateral hippocampus for Hippocampal Avoidance. In the HA-WBRT plan for the PTV i.e., whole brain plus 3 mm margin minus hippocampal avoidance region (H.A.), a dose of 30 Gy in 10 fractions is prescribed over two weeks. In HA-WBRT with SIB, a dose of 30 Gy in 10 fractions over two weeks is prescribed for the PTV, which is the clinical target volume, minus the hippocampal avoidance region (H.A.) minus the PTV Mets (1 mm margin to the GTV). A simultaneous Integrated Boost of 42.5 Gy in 10 # over two weeks is prescribed for PTVmets. Planning was done using a VMAT technique with 6MV F.F.F. beam energy in a treatment planning software. RESULTS The mean B/L hippocampus volume is 3.47 cc. The mean dose of PTV D98% in HA-WBRT plans is 27.45 Gy, whereas in HA-WBRT with S.I.B. is 27.36 Gy (p = 0.90). V30 mean dose in HA-WBRT plans is 93.35%, and the mean dose in HA-WBRT SIB is 91.87% (p = 0.12). PTV D2% mean dose in HA-WBRT Is 36.06 Gy, and in HA-WBRT -S.I.B., it is 40.58 (p< 0.001). The mean bilateral hippocampus Dmax in HA-WBRT is 14.85 Gy, and in HA-WBRT-SIB is 14.25 Gy (p = 0.35). The mean Bilateral hippocampus D100% is 9.14 Gy in HA-WBRT and 9.01 Gy in HA-WBRT-SIB (p = 0.54). The mean brainstem Dmax in HA-WBRT is 36.82 Gy compared to 38.55 Gy in HA-WBRT-SIB (p = 0.02). CONCLUSION In patients planned for a simultaneous boost along with hippocampal sparing whole brain radiotherapy, the mean dose to the hippocampal region did not increase. The Dmax of Brainstem, optic chiasma is significantly higher in HA-WBRT-). Our study, the mean dose to PTVmets is more than 45 Gy and more than 50 Gy to GTV with a BED of more than 65 Gy (α/ß = 10) to the metastases, which is equivalent to some ablative dose regimens. Simultaneous integrated boost along with hippocampal sparing radiotherapy thus helps in sparing the hippocampus and delivering higher doses to the metastases and intermediate doses to the rest of the brain, addressing the microscopic disease.

Abstract
PURPOSE/OBJECTIVE(S) Patients diagnosed with Hepatocellular carcinoma (HCC) complicated with portal vein tumor thrombosis (PVTT) have a limited number of treatment options available and are associated with an overall poor prognosis. With the recent developments in the field of radiation therapy, the role of radiotherapy particularly Stereotactic Body radiotherapy (SBRT) has increased as a loco-regional therapy for HCC. This study was planned to evaluate the role of SBRT in Locally advanced HCC complicated with PVTT and its role as loco-regional therapy. MATERIALS/METHODS We conducted a prospective study that included patients diagnosed with HCC complicated with PVTT Child-Turcotte Pugh (CTP) Class A/B with a maximum score of 7, diagnosed on triple phase Contrast-Enhanced - MRI unsuitable for other ablative procedures. Patients with Bilirubin levels > 4 mg/dl, active Hepatitis, CTP score >7, normal liver volume <700cc or history of prior radiotherapy were excluded from the study. Patients underwent a contrast enhanced 4D-CT simulation with abdominal compression and were planned for SBRT using VMAT technique. Patients were followed-up as per Institute protocol. CECT or MRI for a radiological response was done for response assessment using mRECIST criteria version 1.1. A baseline MRI was done at one-month post-SBRT to understand any RT changes in the liver and to differentiate from tumor progression during the response assessment at three months. RESULTS A total of 22 patients with HCC were recruited and received SBRT to PVTT, with a dosage between 30-42 Gy over 6 fractions treated on alternate days. Patients were assessed post-treatment with triphasic CE-MRI every 3 months as per institute protocol. Five patients had achieved Complete response in form of Portal vein recanalization. Three patients had Partial response to the treatment. Seven patients maintained stable disease status whereas six patients had disease progression during the entire course of treatment. The response rate (CR+PR) to treatment was 36.3% at the time of analysis. The Overall Response rate (CR+PR+SD) was 69%. No grade 3 or 4 toxicities were observed and treatment was tolerated well by patients. Kaplan-Meier method was applied to calculate the survival probability at various follow-up intervals. The median time for overall survival was 25 months ((95% CI: 15-35). Out of the 22 subjects included in the study, 6 patients died. There was a 78% survival probability at 12 months and a 68% survival probability at 18 months of follow-up. CONCLUSION This prospective single-arm study demonstrated the vital role of SBRT in the treatment of Hepatocellular carcinoma with Portal vein tumor thrombosis and its efficacy in terms of achieving excellent local control with relatively lesser toxicities compared with existing treatment modalities. Patients have shown benefit post-treatment in terms of thrombus reduction and restoration of Portal vein flow making them suitable for further treatment like Resection or TACE.

Abstract
PURPOSE/OBJECTIVE(S) The objectives of this study are: 1) To compare the acute toxicity caused in the treatment of locally advanced cervical cancer (LACC) treated with weekly multiple applications vs. a single application for image-guided intracavitary High Dose Rate (HDR) brachytherapy (BT) after External Beam Radiation Therapy (EBRT) 2) To compare the loco-regional control of cancer at six months in the two arms MATERIALS/METHODS: In a prospective study, 40 patients with biopsy-proven LACC with FIGO-2018 stage IIB-IIIC1 disease, underwent EBRT to the pelvis at a dose of 50.4 Gy/ 28 fractions over 5.5 weeks with weekly concurrent cisplatin. After completion of EBRT, they were randomized into two arms with 20 patients each. In the Control arm (Arm-A), BT sessions were given with weekly 3 applications whereas, in the experimental arm (Arm-B), all the sessions were given with a single application at 6-12 hours intervals with aim of the high-risk clinical target volume receiving >80 Gy EQD2 and 2 cm3 of the bladder and rectum/sigmoid receiving <85 Gy and <75 Gy, respectively. The OAR contouring was done on CT RESULTS: All 40 patients were treated as per protocol. The mean duration of treatment including EBRT and BT was 73.15 days [95% CI 68.63-77.66] in Arm A and 55.85 days [95% CI 52.11-59.58] in Arm B which was significant. After 6 months, 37 patients came for follow-up, all 19 patients in Arm A had Grade 1 or Grade 2 rectal toxicity. In Arm B as well all 18 patients had Grade 1 or Grade 2 rectal toxicity. Bladder toxicity was Grade 1 or Grade 2 in 18 patients and Grade 3 severity in 1 patient among Arm A. Among 18 patients of Arm B, bladder toxicity of Grade 1 or Grade 2 was seen in 16 patients, and 2 patients had grade 3 toxicity. 2 patients in Arm A and 3 in Arm B complained of Grade 1 urinary incontinence. Moreover, Abdominal pain at 6 months was of Grade 1 in around 6 patients in Arm A but 14 patients had abdominal pain in Arm B which was of Grade 1 in 8, 4 had grade 2 and 2 patients had grade 3 severity abdominal pain. In the monthly analysis of acute toxicity, none of the patients showed Grade 3 or 4 toxicity at the 1st, 2nd, or 3rd month of completion of treatment. When comparing local control in both arms at 6 months, 2 patients had treatment failure in the Experimental Arm compared to only 1 patient in the Control Arm CONCLUSION: Single Application Multiple Fraction Intracavitary Brachytherapy post concurrent CTRT is a safe option for the treatment of locally advanced cervical cancer. When compared to the weekly application arm, single-application ICRT showed a comparable acute toxicity profile and comparable local control rates as well. Some patients in Single Application Arm showed abdominal pain which needs to be investigated with further trials. The overall treatment time in the single application arm is significantly lower than the standard weekly application arm.

Abstract
PURPOSE/OBJECTIVE(S) Biological Response in Hepatocellular carcinoma (HCC) is measured in terms of serum alpha-fetoprotein (AFP) which is elevated in nearly 60% HCC patients at baseline and is directly related to the severity of the disease. This biological response is defined as the reduction of more than 50% from the baseline levels and is associated with an increased percentage of tumor necrosis and is directly related to increased loco-regional control. Patients diagnosed with HCC have very limited treatment modalities. With the recent advances in the field of radiation therapy and the development of Stereotactic Body radiotherapy (SBRT), the role of radiotherapy has increased as a loco-regional modality for HCC. In this single-arm prospective study, we evaluated the biological response post-SBRT in patients diagnosed with HCC. MATERIALS/METHODS We conducted a prospective study that included patients diagnosed with HCC with baseline elevation of serum AFP, Child-Turcotte Pugh (CTP) Class A/B with a maximum score of 7. Patient's serum AFP levels were recorded at baseline, pre-treatment, and post-treatment. The biological response was measured at 3 months post-treatment and compared with the baseline serum AFP levels using Wilcoxon signed rank test. RESULTS A total of 14 patients with HCC were recruited and received SBRT to the target lesion, with a dose between 30-42 Gy over 6 fractions treated on alternate days. Patients were assessed post-treatment at one month with triphasic CEMRI and serum AFP levels. 12 out of 14 patients (85.71%) had a biological response at 3 months follow-up and levels showed further decline unless a progression was found. The median (IQR) serum AFP level was 1131 ng/ml (359-5668 ng/ml) at baseline. Post-treatment serum AFP levels had a median (IQR) value of 156 ng/ml (15-372 ng/ml) showing a near reduction of 86% from baseline, which was significant. 2/14 pts (14.28%) showed no reduction or even increase in serum AFP levels post-treatment. CONCLUSION This prospective single-arm study demonstrated the vital role of SBRT in the treatment of HCC and its importance in achieving a better disease control. The response was achieved in 86% of patients with marked reduction of nearly 90% in serum AFP levels as compared to the baseline and increased median OS and PFS as compared to patients not receiving radiotherapy. Further prospective studies are warranted to confirm our findings.

Abstract
PURPOSE/OBJECTIVE(S) A substantial proportion of patients with muscle invasive bladder cancer do not receive curative intent therapy, especially if unfit for or refuse radical cystectomy. Concurrent chemoradiation is an effective alternative to radical cystectomy, however systemic radio-sensitizing chemotherapy may have off target side effects. A Phase I study is accruing which will investigate the concurrent administration of a bladder cancer targeted antibody drug conjugate (Sacituzumab Govitecan) with radiotherapy. MATERIALS/METHODS This trial in progress is a Phase I study of Adaptive RADiation therapy with concurrent Sacituzumab Govitecan (SG) for bladder preservation in patients with muscle invasive bladder cancer (MIBC). Eligible patients will have localized muscle invasive bladder cancer (MIBC) confined to the bladder. The initial cohort is expected to accrue 20 patients. The primary endpoint is to establish the safety, tolerability, and feasibility of bladder preservation therapy treatment with concurrent SG and adaptive image-guided radiation therapy for patients with localized MIBC. The secondary endpoints are to determine the bladder intact event-free survival (BI-EFS) with concurrent SG and radiation therapy for MIBC and compare to historical controls with other concurrent chemoradiation regimens. BI-EFS is defined as the time from treatment to the first documented occurrence of residual/recurrent MIBC, nodal or distant metastases on imaging, radical cystectomy, or death from any cause. Sacituzumab Govitecan targets TROP-2, a surface protein expressed in urothelial cancers of the bladder. SG will be delivered IV, 10 mg/kg, 21-day cycles for 1 loading cycle prior to radiation and two subsequent cycles with concurrent adaptive radiotherapy over a period of 6 weeks (64 Gy). Correlative objectives (Supported by NCI/NIH U54) and will involve 1) elucidation of the genetic and microenvironmental mechanisms that drive efficacy and resistance to combined ADC plus radiation therapy and 2) characterization of tumor clonal dynamics, immune repertoire editing, and imaging changes following treatment with SG plus radiation. RESULTS To be determined. CONCLUSION To be determined.

Abstract
OBJECTIVE To synthesize the role of secondary cytoreduction in recurrent ovarian cancer from the results of randomized studies. METHODS We conducted a meta-analysis of randomized controlled trials which compared secondary cytoreductive surgery versus no surgery in patients with platinum sensitive relapsed ovarian cancer. Individual patient data for overall survival and progression free survival were manually extracted from published survival curves, for whole study populations and subgroups based on completeness of surgical resection and bevacizumab use, using WebPlotDigitizer software. Overall survival and progression free survival curves for each study and the combined population were reconstructed from extracted data. RESULTS Three studies with 1249 patients were included, of whom complete resection was achieved in 427 (34.2%) patients. In individual patient data analysis of the whole study population with 562 deaths, there was no significant difference in overall survival between the surgery and no surgery groups (median 52.8 vs 52.1 months, respectively, hazard ratio (HR) 0.94, 95% confidence interval (CI) 0.80 to 1.11; p=0.5) but the surgery group had significantly longer progression free survival compared with the no surgery group (median 18.3 vs 14.4 months, respectively, HR 0.70, 95% CI 0.62 to 0.80; p<0.001). In subgroup analyses, overall survival was significantly longer in the complete cytoreduction subgroup compared with the no surgery group (median 62.0 vs 52.1 months, respectively, HR 0.70, 95% CI 0.57 to 0.92; p<0.001) while overall survival was significantly worse in the incomplete cytoreduction subgroup compared with the no surgery group (median 34.2 vs 52.1 months, respectively, HR 1.72, 95% CI 1.38 to 2.14; p<0.001). In the no bevacizumab subgroup, there was no significant overall survival difference between the surgery and no surgery groups (median 49.3 vs 47.0 months, HR 0.86, 95% CI 0.67 to 1.10; p=0.25). CONCLUSIONS Secondary cytoreductive surgery among women with platinum-sensitive relapsed ovarian cancer did not lead to significant benefit in overall survival although it increased progression free survival. However, overall survival was significantly longer among patients in whom complete cytoreduction was possible compared with no surgery.
