Abstract
AIMS To evaluate the incidence and pattern of contralateral nodal relapse (CLNR), contralateral nodal relapse-free survival (CLNRFS) and risk factors predicting CLNR in well-lateralised oral cavity cancers (OCC) treated with unilateral surgery and adjuvant ipsilateral radiotherapy with or without concurrent chemotherapy. MATERIALS AND METHODS Consecutive patients of well-lateralised OCC treated between 2012 and 2017 were included. The primary endpoint was incidence of CLNR and CLNRFS. Univariable and multivariable analyses were carried out to identify potential factors predicting CLNR. RESULTS Of the 208 eligible patients, 21 (10%) developed isolated CLNR at a median follow-up of 45 months. The incidence of CLNR was 21.3% in node-positive patients. CLNR was most common at level IB (61.9%) followed by level II. The 5-year CLNRFS and overall survival were 82.5% and 57.7%, respectively. Any positive ipsilateral lymph node (P = 0.001), two or more positive lymph nodes (P < 0.001), involvement of ipsilateral level IB (P = 0.002) or level II lymph node (P < 0.001), presence of extranodal extension (P < 0.001), lymphatic invasion (P = 0.015) and perineural invasion (P = 0.021) were significant factors for CLNR on univariable analysis. The presence of two or more positive lymph nodes (P < 0.001) was an independent prognostic factor for CLNR on multivariable analysis. CLNR increased significantly with each increasing lymph node number beyond two compared with node-negative patients. CONCLUSION The overall incidence of isolated CLNR is low in well-lateralised OCC. Patients with two or more positive lymph nodes have a higher risk of CLNR and may be considered for elective treatment of contralateral neck.

Abstract
PURPOSE The objective of this study was to compare clinical outcomes of intensity-modulated radiation therapy (IMRT) alone versus IMRT + brachytherapy (BT) in patients with T1-T2N0M0 oropharyngeal squamous cell cancers (OPSCC). METHODS AND MATERIALS This open-label randomized controlled trial was conducted at Tata Memorial Hospital, Mumbai, India. Patients with stage I and II OPSCC were considered for IMRT to a dose of 50 Gy/25 fractions/5 weeks in phase I followed by randomization (1:1) to further treatment with IMRT (20 Gy/10 fractions/2 weeks) or BT (192Ir high dose rate, 21 Gy/7 fractions/2 fractions per day). The primary endpoint of the trial was the reduction in xerostomia at 6 months evaluated using 99mTc salivary scintigraphy. Severe salivary toxicity (xerostomia) was defined as posttreatment salivary excretion fraction ratio <45%. Secondary endpoints were local control, disease-free survival, and overall survival. RESULTS Between November 2010 and February 2020, 90 patients were randomized to IMRT (n = 46) alone or IMRT + BT (n = 44). Eleven patients (8 residual/recurrent disease, 2 lost to follow-up, 1 second primary) in the IMRT arm and 9 patients (8 residual/recurrence, 1 lost to follow-up) in the BT arm were not evaluable at 6 months for the primary endpoint. At 6 months, xerostomia rates using salivary scintigraphy were 14% (5/35: 95% CI, 5%-30%) in the BT arm while it was seen in 44% (14/32: 95% CI, 26%-62%) in the IMRT arm (P = .008). Physician-rated Radiation Therapy Oncology Group grade ≥2 xerostomia at any time point was observed in 30% of patients (9/30) in the IMRT arm and 6.7% (2/30) in the BT arm (P = .02). At a median follow-up of 42.5 months, the 3-year local control in the IMRT arm was 56.4% (95% CI, 43%-73%) while it was 66.2% (95% CI, 53%-82%) in the BT arm (P = .24). CONCLUSIONS The addition of BT to IMRT for T1-T2N0M0 OPSCC results in a significant reduction in xerostomia. This strongly supports the addition of BT to IMRT in suitable cases.

Abstract
Following completion of adjuvant radiation and chemotherapy imaging surveillance forms a major role in the management of diffuse gliomas. The primary role of imaging is to detect recurrences earlier than clinical symptomatology. Magnetic resonance imaging (MRI) is considered the gold standard in follow-up protocols owing to better soft tissue delineation and multiparametric nature. True recurrence can often mimic treatment-related changes, it is of paramount importance to differentiate between the two entities as the clinical course is divergent. Addition of functional sequences like perfusion, spectroscopy and metabolic imaging can provide further details into the microenvironment. In equivocal cases, a follow-up short interval imaging might be obtained to settle the diagnostic dilemma. Here, we present a patient with diagnosis of recurrent oligodendroglioma treated with adjuvant chemoradiation, presenting with seizures five years post-completion of chemotherapy for recurrence. On MRI, subtle new onset gyral thickening of the left frontal region with mild increase in perfusion and patchy areas of raised choline. FET-PET (fluoro-ethyltyrosine) showed an increased tumour-to-white matter (T/Wm) ratio favouring tumour recurrence. Based on discussion in a multi-disciplinary joint clinic, short interval follow-up MRI was undertaken at two months showing decrease in gyral thickening and resolution of enhancing areas in left frontal lobe. Repeat imaging one year later demonstrated stable disease status without further new imaging findings. Given the changes resolving completely without any anti-tumoral intervention, we conclude this to be peri-ictal pseudoprogression, being the second such case described in India.

Abstract
BACKGROUND Anhedonia is a transdiagnostic symptom of severe mental illness (SMI) and emerges during adolescence. Possible subphenotypes and neural mechanisms of anhedonia in adolescents at risk for SMI are understudied. METHODS Adolescents at familial risk for SMI (N = 81) completed anhedonia (e.g., consummatory, anticipatory, social), demographic, and clinical measures and one year prior, a subsample (N = 46) completed fMRI scanning during a monetary reward task. Profiles were identified using k-means clustering of anhedonia type and differences in demographics, suicidal ideation, impulsivity, and emotional processes were examined. Moderation analyses were conducted to investigate whether levels of brain activation of reward regions moderated the relationships between anhedonia type and behaviors. RESULTS Two-clusters emerged: a high anhedonia profile (high-anhedonia), characterized by high levels of all types of anhedonia, (N = 32) and a low anhedonia profile (low-anhedonia), characterized by low levels of anhedonia types (N = 49). Adolescents in the high-anhedonia profile reported more suicidal ideation and negative affect, and less positive affect and desire for emotional closeness than low-anhedonia profile. Furthermore, more suicidal ideation, less positive affect, and less desire for emotional closeness differentiated the familial high-risk, high-anhedonia profile adolescents from the familial high-risk, low-anhedonia profile adolescents. Across anhedonia profiles, moderation analyses revealed that adolescents with high dmPFC neural activation in response to reward had positive relationships between social, anticipatory, and consummatory anhedonia and suicidal ideation. LIMITATIONS Small subsample with fMRI data. CONCLUSION Profiles of anhedonia emerge transdiagnostically and vary on clinical features. Anhedonia severity and activation in frontostriatal reward areas have value for clinically important outcomes such as suicidal ideation.

Abstract
Medulloblastoma (MB) comprises four broad molecular subgroups, namely wingless (WNT), sonic hedgehog (SHH), Group 3, and Group 4, respectively, with subgroup-specific developmental origins, unique genetic profiles, distinct clinico-demographic characteristics, and diverse clinical outcomes. This is a retrospective audit of clinical outcomes in molecularly confirmed WNT-MB patients treated with maximal safe resection followed by postoperative standard-of-care risk-stratified adjuvant radio(chemo)therapy at a tertiary-care comprehensive cancer centre. Of the 74 WNT-MB patients registered in a neuro-oncology unit between 2004 to 2020, 7 patients accrued on a prospective clinical trial of treatment deintensification were excluded, leaving 67 patients that constitute the present study cohort. The median age at presentation was 12 years, with a male preponderance (2:1). The survival analysis was restricted to 61 patients and excluded 6 patients (1 postoperative mortality plus 5 without adequate details of treatment or outcomes). At a median follow-up of 72 months, Kaplan-Meier estimates of 5-year progression-free survival and overall survival were 87.7% and 91.2%, respectively. Traditional high-risk features, large residual tumour (≥1.5 cm2), and leptomeningeal metastases (M+) did not significantly impact upon survival in this molecularly characterized WNT-MB cohort treated with risk-stratified contemporary multimodality therapy. The lack of a prognostic impact of conventional high-risk features suggests the need for refined risk stratification and potential deintensification of therapy.

Abstract
BACKGROUND The risk of recurrence is overestimated by the Kaplan-Meier method when competing events, such as death without recurrence, are present. Such overestimation can be avoided by using the Aalen-Johansen method, which is a direct extension of Kaplan-Meier that accounts for competing events. Meningiomas commonly occur in older individuals and have slow-growing properties, thereby warranting competing risk analysis. The extent to which competing events are considered in meningioma literature is unknown, and the consequences of using incorrect methodologies in meningioma recurrence risk analysis have not been investigated. METHODS We surveyed articles indexed on PubMed since 2020 to assess the usage of competing risk analysis in recent meningioma literature. To compare recurrence risk estimates obtained through Kaplan-Meier and Aalen-Johansen methods, we applied our international database comprising ~ 8,000 patients with a primary meningioma collected from 42 institutions. RESULTS Of 513 articles, 169 were eligible for full-text screening. There were 6,537 eligible cases from our PERNS database. The discrepancy between the results obtained by Kaplan-Meier and Aalen-Johansen was negligible among low-grade lesions and younger individuals. The discrepancy increased substantially in the patient groups associated with higher rates of competing events (older patients with high-grade lesions). CONCLUSION The importance of considering competing events in recurrence risk analysis is poorly recognized as only 6% of the studies we surveyed employed Aalen-Johansen analyses. Consequently, most of the previous literature has overestimated the risk of recurrence. The overestimation was negligible for studies involving low-grade lesions in younger individuals; however, overestimation might have been substantial for studies on high-grade lesions.

Abstract
INTRODUCTION We evaluate remote consultation for adult patients referred with recurrent sore throat, measuring the effectiveness of the consultation, satisfaction and environmental impact. METHODS Eligible patients were invited to telephone clinics, undertaking a satisfaction survey after consultation, focusing on perceived convenience, satisfaction, cost and travel arrangements (used to calculate potential environmental benefit). Provider opinion was also captured. RESULTS Forty-eight of 60 patients attended, with 38 (63%) eligible for inclusion. Thirty-six of these 38 patients (95%) had a definitive outcome of tonsillectomy (27/38) or discharge (9/38). Thirty-three of the 38 patients (87%) responded to the survey and reported high satisfaction in all arms of questioning (mean Likert ranking = 4.7/5). A mean of 3.76 hours of missed work and 5.17kg carbon dioxide emission equivalents were saved per patient. Provider responses were positive towards ongoing remote consultation use. CONCLUSIONS Telephone consultation for adult patients considered for tonsillectomy is convenient to patients in terms of cost and time, reduces environmental harm and is associated with high patient and provider satisfaction.

Abstract
INTRODUCTION CDKN2A/B homozygous deletion is one of the defining features of grade 4 in IDH-mutant astrocytic tumours. AIM To evaluate CDKN2A/B-deletion in IDH-mutant astrocytic tumours and its clinicopathological impact. MATERIALS AND METHODS CDKN2A/B-deletion was evaluated by Fluorescence in-situ hybridisation (FISH) and interpreted by two recently accepted methods. RESULTS Eighty-three out of 94 cases (histologically-grade 2: 3, grade 3: 46, grade 4: 34) were interpretable on FISH. Concordant CDKN2A/B-deletion was observed in 71% (27/38) of lower-grade tumours (n = 49) and 90% (27/30) of histological grade 4 tumours (n = 34). Both the interpretation methods showed good agreement (Kappa = 0.75). CDKN2A/B-deletion showed an inverse correlation for < 10% MIB-1 labeling index (p = 0.01) while that by method-2 showed a significant correlation for grade 4 (p = 0.02). No significant correlation was observed for any other clinicopathological parameters. Twenty-four patients showed progression/recurrence (including deaths), and no significant difference in frequency of CDKN2A/B deletion was observed among cases with disease progression across different histological grades. CONCLUSIONS CDKN2A/B-deletion was observed across all the histological grades of IDH-mutant astrocytic tumours, expectedly more in the higher grade. FISH, as a method, can be used for the detection of CDKN2A/B homozygous deletion, when there is concordant interpretation.

Abstract
PURPOSE This study aimed to evaluate the volumetric and geometric changes in the parotid glands and target volume during image-guided radiotherapy (IGRT) for locally advanced oropharyngeal cancers. MATERIALS AND METHODS Twenty patients receiving radiotherapy using IGRT at a dose of 70 Gy/35 fractions/7 weeks for locally advanced oropharyngeal cancers were accrued. Radiotherapy planning computed tomography (CT) scans were performed at pre-radiotherapy (RT), 20, 40, and 60 Gy for each patient. Volume changes in target and parotids along with shifts of parotids were assessed with respect to pre-RT scan after co-registration. In study scans, GTVp and GTVn were recontoured as per particular CT. CTV and PTV were copied from planning CT to study CT. CTV was edited from anatomical barriers, and PTV was edited only from the skin in the study CT. The parotids were recontoured on each study scan. The center of mass (COM) of C2 vertebral body was considered as the reference to evaluate its shifts. RESULTS There was a statistically significant percentage regression of ipsilateral and contralateral parotid mean volumes at the rate of 0.85%/0.207 cc and 0.98%/0.26 cc per day, respectively. We observed the mean medial shift of center of mass of ipsilateral parotid of 2.23 mm (p = 0.011) and contralateral parotid of 2.67 mm (p = 0.069) at the end of 60 Gy. GTVp (mean) reduced from 41.87 cc at 0 Gy to 31.13 cc (25.65%) at 60 Gy (p = 0.003), while GTVn (mean) reduced from 19.98 cc at 0 Gy to 10.79 cc (45.99%) at 60 Gy (p = 0.003). There was a statistically significant reduction in CTV and PTV volumes at 60 Gy. CONCLUSION Statistically significant volumetric and geometric changes occurred during intensity-modulated radiation (IMRT), which were most prominent after 40 Gy and were maximum at 60 Gy. There was a medial shift of parotid glands toward the high-dose region. This study can be useful to devise an adaptive radiotherapy strategy.

Abstract
Neural connections of the seventh cranial nerve with its neighboring nerves are common and well documented; however, communication with ansa cervicalis is as yet unknown. We present a case with such a connection found during cadaveric dissection, with hitherto unknown consequences. In this specimen, after giving the marginal mandibular and cervical branches, the cervicofacial division continued distally to communicate with the distal loop of ansa cervicalis. Presence of such connection may result in facial muscle paralysis on injury to the ansa or strap muscle paralysis on injury to the facial nerve, depending on the direction of nerve fibers. Such unusual connections bring to light the need for extreme care during surgeries in the neck to safeguard any such connections and when using the ansa as donor.

Abstract
OBJECTIVE Craniopharyngioma (CP) is a benign neuroepithelial tumor generally treated with maximal safe resection and radiation therapy (RT) in incompletely resected CP or in recurrent tumors to achieve long-term control. We analyzed the clinical outcomes of patients with CPs treated with a multimodality approach. PATIENTS AND METHODS A retrospective clinical audit of histologically proven CPs registered between 2008 and 2019 at a specialized neuro-oncology center in India was performed. Time-to-event outcomes (overall survival [OS] and progression-free survival [PFS]) were analyzed. RESULTS One hundred and twenty-two patients with CP were analyzed. The median age of the population was 14 years (interquartile range [IQR], 8-26) with a significant male preponderance. Gross total resection was achieved in only 25% of patients. At a median follow-up of 57.1 months (IQR, 27.8-87.8), 5-year estimates of PFS and OS were 52% (95% confidence interval, 46%-63.4%) and 85.8% (95% confidence interval, 78.6%-93%), respectively. Recurrence or progression was observed in 48 of 122 patients (39.3%) at a median time of 84.4 months (IQR, 24.7-174.8). On multivariate analysis, the absence of residual disease (P = 0.004), near-total resection (P = 0.035), and use of up-front adjuvant RT (P < 0.001) significantly improved the 5-year PFS, whereas the absence of extracavernous extension (P = 0.058) and any use of postoperative RT (P = 0.026) significantly improved the 5-year OS. CONCLUSIONS This study represents one of the largest single-institutional series of CPs, showing improved PFS with up-front adjuvant RT in most cases of CP. Deferring adjuvant RT should be considered only in patients with no evidence of residual disease (as shown on dedicated sellar imaging) after primary surgery.

Abstract
OBJECTIVE Conventional injection medialisation laryngoplasty techniques may be compromised by patient-specific factors such as marked kyphosis, an anteriorly positioned larynx or intolerance to nasendoscopy. This paper describes a technique for successful injection medialisation laryngoplasty where conventional methods are precluded, in an 88-year-old man with presbyphonia on a background of Parkinson's disease. METHODS After induction of general anaesthesia, a transoral introducing needle, shaped by tactile manipulation to match the curvature of a 'C-MAC' intubating video-laryngoscope 'D-blade' attachment, was introduced until visible above the glottis. The implant material was then injected into the paraglottic space as normal until satisfactory medialisation of the vocal fold was achieved. RESULTS When reviewed in the out-patient clinic four weeks later, the patient's post-operative Voice Handicap Index score fell to 6, from a pre-operative score of 21. CONCLUSION By utilising commonly available equipment and anaesthetic support to recreate the views and access conventional nasendoscopy and laryngoscopy facilitate, this novel procedure provides a viable and proven alternative in uncommon but challenging cases.

Abstract
AIMS To report longitudinal quality of life (QoL) outcomes and survival in patients with poor-prognosis high-grade glioma (HGG) treated with palliative hypofractionated radiotherapy. MATERIALS AND METHODS Patients with poor-prognosis HGG were accrued on a prospective study of short-course palliative hypofractionated radiotherapy (35 Gy/10 fractions/2 weeks). The European Organization for Research and Treatment of Cancer QoL core questionnaire (QLQ-C30) and brain cancer module (BN20) were used in English or validated Indian vernacular languages (Hindi and Marathi) for QoL assessment at baseline (before radiotherapy), the conclusion of radiotherapy, 1 month post-radiotherapy and subsequently at 3-monthly intervals until disease progression/death. Baseline QoL scores were compared with corresponding scores from a historical HGG cohort. Summary QoL scores were compared longitudinally over time by related samples Friedman's two-way test. Progression-free survival and overall survival were calculated using the Kaplan-Meier method and reported as 1-year estimates with 95% confidence intervals. RESULTS Forty-nine (89%) of 55 patients completed the planned course of hypofractionated radiotherapy. Longitudinal QoL data were available in 42 (86%) of 49 patients completing radiotherapy, comprising the present cohort. The median age of included patients, comprised mainly of glioblastoma patients (81%), was 57 years, with an interquartile range (IQR) of 50-66 years and a median baseline Karnofsky score of 60 (IQR = 50-60). Baseline QoL scores were significantly worse for several domains compared with a historical institutional cohort of HGG patients treated previously with conventionally fractionated radiotherapy, indicating negative selection bias. QoL scores remained stable for most domains after palliative hypofractionated radiotherapy, with statistically significant improvements in fatigue (P = 0.032), dyspnoea (P = 0.042) and motor dysfunction (P = 0.036) over time. At a median follow-up of 8 months, Kaplan-Meier estimates of 1-year progression-free survival and overall survival were 33.3% (95% confidence interval 21.7-51.1%) and 38.1% (95% confidence interval 25.9-56%), respectively. CONCLUSION Short-course palliative hypofractionated radiotherapy in patients with poor-prognosis HGG is associated with stable and/or improved QoL scores in several domains, making it a viable resource-sparing regimen.

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
OBJECTIVE To assess the diagnostic performance of response assessment 18F-fluorodeoxyglucose positron emission tomography/contrast-enhanced computed tomography (FDG-PET/CECT) following definitive radio(chemo)therapy in head and neck squamous cell carcinoma (HNSCC) using Neck Imaging Reporting and Data System (NI-RADS). STUDY DESIGN A retrospective analysis from a prospectively maintained dataset. SETTING Tertiary-care comprehensive cancer center in a low-middle-income country. METHODS Adults with newly diagnosed, biopsy-proven, nonmetastatic HNSCC treated with definitive radio(chemo)therapy were included. Posttreatment response assessment FDG-PET/CECT scans were retrospectively assigned NI-RADS categories (1-3) for the primary site, neck, and both sites combined. Locoregional recurrence occurring within 2-years was defined as the event of interest. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy were calculated. Locoregional control stratified by NI-RADS categories was computed with the Kaplan-Meier method and compared using the log-rank test. RESULTS Posttreatment FDG-PET/CECT scans were available in 190 patients constituting the present study cohort. Sensitivity, specificity, PPV, NPV, and overall accuracy of the NI-RADS template for the primary site was 73.5%, 81.4%, 46.3%, 93.4%, and 80.0%, respectively. Similar metrics for the neck were 72.7%, 87.5%, 43.2%, 96.1%, and 85.8%, respectively. Combining primary site and neck, the corresponding metrics of diagnostic accuracy were 84.4%, 69.7%, 46.3%, 93.5%, and 73.2%, respectively. At a median follow-up of 40 months, Kaplan-Meier estimates of 2-year locoregional control were significantly higher for NI-RADS category 1 (94.2%) compared to NI-RADS category 2 (69.4%) and category 3 (20.4%), respectively (stratified log-rank p < .0001). CONCLUSION FDG-PET/CECT using the NI-RADS template is associated with good diagnostic performance and prognostic utility in HNSCC treated with definitive radio(chemo)therapy.

Abstract
Aim Early diagnosis of paediatric brain tumors significantly improves the outcome. The aim is to study magnetic resonance imaging (MRI) features of paediatric brain tumors and to develop an automated segmentation (AS) tool which could segment and classify tumors using deep learning methods and compare with radiologist assessment. Methods This study included 94 cases, of which 75 were diagnosed cases of ependymoma, medulloblastoma, brainstem glioma, and pilocytic astrocytoma and 19 were normal MRI brain cases. The data was randomized into training data, 64 cases; test data, 21 cases and validation data, 9 cases to devise a deep learning algorithm to segment the paediatric brain tumor. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the deep learning model were compared with radiologist's findings. Performance evaluation of AS was done based on Dice score and Hausdorff95 distance. Results Analysis of MRI semantic features was done with necrosis and haemorrhage as predicting features for ependymoma, diffusion restriction and cystic changes were predictors for medulloblastoma. The accuracy of detecting abnormalities was 90%, with a specificity of 100%. Further segmentation of the tumor into enhancing and non-enhancing components was done. The segmentation results for whole tumor (WT), enhancing tumor (ET), and non-enhancing tumor (NET) have been analyzed by Dice score and Hausdorff95 distance. The accuracy of prediction of all MRI features was compared with experienced radiologist's findings. Substantial agreement observed between the classification by model and the radiologist's given classification [K-0.695 (K is Cohen's kappa score for interrater reliability)]. Conclusions The deep learning model had very high accuracy and specificity for predicting the magnetic resonance (MR) characteristics and close to 80% accuracy in predicting tumor type. This model can serve as a potential tool to make a timely and accurate diagnosis for radiologists not trained in neuroradiology.

Abstract
Primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) is an uncommon extranodal lymphoma that accounts for more than 95% of all the CNS lymphomas. Unlike its systemic/nodal counterpart, which is currently subtyped into cell-of origin (COO) subtypes, its feasibility and utility are largely debatable in PCNS-DLBCL. Objectives To classify PCNS-DLBCL into COO-subtypes based on immunohistochemical algorithms by Hans and Choi and evaluate concordance between the two. A further aim is to investigate the clinicoradiological and histomorphological parameters of the subtypes thus obtained. Materials and Methods As many as 143 cases of primary CNS lymphoma were evaluated by immunohistochemistry for CD10, BCL6, MUM1, GCET, and FOXP1 and based on which the said 143 cases were further classified into COO subtypes using Hans and Choi algorithms. Results Mean age was 53.8 years with marginal male preponderance and predominantly centroblastic morphology (75.5%). CD 10 was positive in 8.9% of the cases, BCL6 in 58.6%, MUM1 in 89.9%, GCET in 32.9%, and FOXP1 in 79.5%. As much as 84.9% cases were of non-germinal center B-cell (GCB) subtype and 15.1% cases were of GCB subtype as determined based on Hans algorithm. Furthermore, 90.7% cases were of activated B-cell (ABC) subtype and 9.3% cases were of GCB subtype according to Choi algorithm. A 91.8% concordance was observed between Hans and Choi algorithms. Among the 6 discordant cases, 5 cases were subtyped as GCB by Hans and ABC by Choi and 1 case as ABC by Hans and GCB by Choi. Conclusion Most of PCNS-DLBCLs are of non-GCB/ABC COO subtype, but inconsistences abound in the utility of IHC algorithms in PCNS-DLBCL COO subtypes.

Abstract
Grading of gliomas is a piece of critical information related to prognosis and survival. Classifying glioma grade by semantic radiological features is subjective, requires multiple MRI sequences, is quite complex and clinically demanding, and can very often result in erroneous radiological diagnosis. We used a radiomics approach with machine learning classifiers to determine the grade of gliomas. Eighty-three patients with histopathologically proven gliomas underwent MRI of the brain. Whenever available, immunohistochemistry was additionally used to augment the histopathological diagnosis. Segmentation was performed manually on the T2W MR sequence using the TexRad texture analysis softwareTM, Version 3.10. Forty-two radiomics features, which included first-order features and shape features, were derived and compared between high-grade and low-grade gliomas. Features were selected by recursive feature elimination using a random forest algorithm method. The classification performance of the models was measured using accuracy, precision, recall, f1 score, and area under the curve (AUC) of the receiver operating characteristic curve. A 10-fold cross-validation was adopted to separate the training and the test data. The selected features were used to build five classifier models: support vector machine, random forest, gradient boost, naive Bayes, and AdaBoost classifiers. The random forest model performed the best, achieving an AUC of 0.81, an accuracy of 0.83, f1 score of 0.88, a recall of 0.93, and a precision of 0.85 for the test cohort. The results suggest that machine-learning-based radiomics features extracted from multiparametric MRI images can provide a non-invasive method for predicting glioma grades preoperatively. In the present study, we extracted the radiomics features from a single cross-sectional image of the T2W MRI sequence and utilized these features to build a fairly robust model to classify low-grade gliomas from high-grade gliomas (grade 4 gliomas).

Abstract
Background and Objective Primary intracranial germ cell tumors (ICGCTs) are rare and are histologically classified as germinomas and non-germinomatous with distinctive prognostic and therapeutic implications. ICGCTs, essentially due to the inherent difficulty of surgical access, pose different challenges and management connotations than their extracranial counterparts. This is a retrospective analysis of histologically verified ICGCTs, which was undertaken to evaluate various clinicopathological features and their implications on patient management. Materials and Methods Eighty-eight histologically diagnosed cases (over 14 years) of ICGCT at our institute formed the study cohort and were classified into germinoma and non-germinomatous germ cell tumors (NGGCTs). Additionally, germinomas were further subdivided on the basis of 1) tumor marker (TM) levels, as germinoma with normal TM, mildly elevated TM, and markedly elevated TM and 2) radiology features, as germinomas with typical radiology and atypical radiological features. Results ICGCT with age ≤6 years (P = 0.049), elevated TM (P = 0.047), and NGGCT histology (P < 0.001) showed significantly worse outcomes. Furthermore, germinomas with markedly elevated TM and certain atypical radiological features showed prognosis akin to NGGCT. Conclusions Analysis of our largest single cancer center Indian patient cohort of ICGCT shows that inclusion of age ≤6 years, raised TM, and certain radiological features may assist clinicians in overcoming the limitations of surgical sampling, with better prognostication of histologically diagnosed germinomas.

Abstract
BACKGROUND Re-irradiation (ReRT) is an effective treatment modality in appropriately selected patients with recurrent/progressive high-grade glioma (HGG). The literature is limited regarding recurrence patterns following ReRT, which was investigated in the current study. METHODS Patients with available radiation (RT) contours, dosimetry, and imaging-based evidence of recurrence were included in the retrospective study. All patients were treated with fractionated focal conformal RT. Recurrence was detected on imaging with magnetic resonance imaging (MRI) and/ or amino-acid positron emission tomography (PET), which was co-registered with the RT planning dataset. Failure patterns were classified as central, marginal, and distant if >80%, 20-80%, or <20% of the recurrence volumes were within 95% isodose lines, respectively. RESULTS Thirty-seven patients were included in the current analysis. A total of 92% of patients had undergone surgery before ReRT, and 84% received chemotherapy. The median time to recurrence was 9 months. Central, marginal, and distant failures were seen in 27 (73%), 4 (11%), and 6 (16%) patients, respectively. None of the patient-, disease-, or treatment-related factors were significantly different across different recurrence patterns. CONCLUSION Failures are seen predominantly within the high-dose region following ReRT in recurrent/ progressive HGG.

Abstract
BACKGROUND To assess the efficacy of prophylactic versus reactive feeding strategy in oral cavity squamous cell carcinoma (OCSCC) patients receiving adjuvant radiation therapy (RT). METHODS This was a post hoc analysis of patients of OCSCC enrolled in a randomized trial comparing three adjuvant strategies. In this trial, till 2010, a prophylactic feeding approach was followed for all patients. Since January 2011, a reactive feeding approach was followed. RESULTS Two hundred and sixty-eight in each cohort (total n = 526) were eligible for analysis after propensity score matching. At 6 weeks post-RT completion, the median weight loss in the prophylactic versus reactive cohort was 5 versus 3 kg, p = 0.002. At all other time points until 1 year, the median weight loss was lesser in reactive than in the prophylactic cohort. CONCLUSIONS A reactive feeding tube approach should be preferred for OCSCC receiving adjuvant RT.

Abstract
Primary diffuse leptomeningeal melanocytosis (PDLM) is an extremely rare CNS tumor with nonspecific clinicoradiologic features that overlap considerably with aseptic meningitis posing significant diagnostic and therapeutic challenges. We present one such case report of a patient treated empirically at first presentation as aseptic viral meningitis based on MRI and CSF analysis. Diagnosis of PDLM was established subsequently through meningeal biopsy that demonstrated a melanocytic tumor with fine granular melanin pigment without significant mitoses. Her systemic and ocular examination was unremarkable. Whole-body 18F-fluorodeoxyglucose PET/CT (FDG-PET/CT) did not identify any other primary site. Following ventriculoperitoneal shunt to relieve hydrocephalus, she was treated with definitive craniospinal irradiation plus whole-brain boost and remains stable on periodic clinicoradiologic surveillance. Optimal management of PDLM lacks consensus with role of radiotherapy, chemotherapy, targeted therapy and immunotherapy being controversial.

Abstract
BACKGROUND Limited data exists regarding the impact of intensification of adjuvant therapy in resected Oral Cavity Squamous Cell Carcinomas (OCSCC) with adverse prognostic features on histopathology. PATIENTS AND METHODS This was a three-arm phase III, randomised trial including patients with resected advanced OCSCC. Randomisation was done in a 1:1:1 ratio: Arm-A- standard adjuvant radiation therapy (RT) 60Gy/30 fractions over 6 weeks versus Arm-B-concurrent chemoradiation versus Arm-C-accelerated radiation therapy (6 d a week). The trial was powered to detect an absolute difference of 10% in 5-year Locoregional Control (LRC). RESULTS The trial was conducted between June 2005 and March 2013. Majority of the patients were males, had T3-T4 disease, had N2-N3 nodal status and had Extra-Capsular Extension (ECE) in nodes. The median follow-up was 95.9 months. There was no difference between the three arms (A versus B versus C) for 10-year locoregional control (LRC): 60.2% versus 61.4% versus 65.7%, p = 0.57; disease free survival (DFS): 37.4% versus 43.9% versus 39.6%, p = 0.40; or Overall Survival (OS): 39.7% versus 46.6% versus 40.4%, p = 0.40. There was no benefit of intensification with either modality in patients with any single adverse pathological factor. A benefit of intensification could be seen in patients with a combination of high-risk features: T3-T4 primary tumours with N2-N3 nodes along with ECE for DFS (Arm B versus Arm A HR) = 0.53, Arm C versus Arm A HR = 0.63) and OS (Arm B versus Arm A HR = 0.58, Arm C versus Arm A HR = 0.60). CONCLUSIONS All optimally resected OCSCC with adverse features did not benefit from intensification of adjuvant therapy. Only a cohort of patients with a combination of high-risk features are likely candidates for intensification. CLINICAL TRIAL REGISTRATION NCT00193843.

Abstract
PURPOSE To report frequency and timing of adaptive radiotherapy (ART) and assess patient, disease, and treatment-related characteristics potentially triggering the need for such adaptive replanning in head and neck squamous cell carcinoma (HNSCC). METHODS Medical records of HNSCC patients treated with definitive intensity modulated radiation therapy (IMRT) with or without concurrent systemic chemotherapy were reviewed retrospectively to identify patients undergoing image-guidance triggered adaptive replanning. Clinico-demographic characteristics of patients undergoing ART were compared with patients treated without adaptation using the chi-square test. RESULTS Two hundred patients with squamous cell cancers of the oropharynx, larynx, or hypopharynx treated with definitive IMRT between 2014 to 2019 comprised the study cohort. Twenty-seven (13.5%) patients underwent adaptive replanning during treatment at a median of 17 fractions (inter-quartile range 14-24 fractions). There were no significant differences in the baseline patient (age, gender), disease (site of primary, staging/grouping), and treatment-related characteristics (dose-fractionation, chemotherapy usage) in patients undergoing ART compared to those treated without adaptation. Weight loss during IMRT emerged as a significant factor predicting the need for ART; patients having ≥10% weight loss from baseline were more likely to undergo treatment adaptation compared to patients with <10% weight loss (p = 0.0002). There was variable impact of ART on dose-volume statistics of organs-at-risk such parotid glands and spinal cord. CONCLUSION Image-guidance triggered ART for HNSCC is not associated with significant improvement in OAR dosimetry. However, weight loss during definitive IMRT can be a potentially useful trigger for identifying patients who are most likely to benefit from such adaptive replanning.

Abstract
Novel biological insights have established that medulloblastoma is a heterogenous disease comprising four broad molecular subgroups - WNT, SHH, Group 3, and Group 4 respectively, resulting in the incorporation of molecular/genetic information in 5th edition of WHO classification and contemporary risk-stratification. Concerns regarding therapy-related late toxicity in long-term survivors have led to systematic attempts at treatment de-intensification in good-risk medulloblastoma. Given the excellent survival (>90%) of WNT-pathway medulloblastoma, prospective clinical trials have focused on optimization of therapy to balance survival versus quality of survival. The currently accepted definition of low-risk WNT-pathway medulloblastoma includes children <16 years of age with residual tumour <1.5 cm2 and no evidence of metastases. This systematically excludes adolescents and young adults who have been perceived to have worse outcomes. We have previously reported long-term survival of our adolescent and young adult cohort that were largely comparable to childhood medulloblastoma. We now report on molecularly characterized WNT-subgroup patients treated between 2004-2020 with risk-stratified multi-modality therapy to identify differences between childhood (<15 years) versus adolescent and young adults (>15 years). Despite modest differences in disease status at presentation and treatment modality, there were no significant differences in patterns of failure or survival between childhood versus adolescent and young adult WNT-pathway medulloblastoma. Two de-intensification trials in low-risk WNT-pathway medulloblastoma - first testing omission of upfront craniospinal irradiation and second a primary chemotherapy approach after surgery - had to be terminated prematurely due to unacceptably high relapse rates suggesting that craniospinal irradiation remains an integral component of treatment. The presence of TP53 mutations and OTX2 gains have recently been reported as independent negative prognostic factors in a multi-institutional cohort of WNT-pathway medulloblastoma raising questions on eligibility of such patients for de-escalation trials. The definition of low-risk WNT-pathway medulloblastoma may need to be refined in light of recent clinical data and newer biological information.

Abstract
AbstractCentral nervous system (CNS) tumors are the second most common cause of cancer in children when incidence rates of cancer are estimated according to the Indian population dynamics based on 2011 consensus. As per the estimates, CNS tumors account for 20.1% of cancer burden in children aged between 0 and 14 years and 16.8% when 0 to 19 years age group is considered. The most common pediatric brain tumors are astrocytoma and medulloblastoma followed by other embryonal tumors, craniopharyngioma, and ependymal tumors. The incidence of CNS tumors in children from India is similar to the western high-income countries, other than slightly higher incidence of craniopharyngioma in Indian children.

Abstract
BACKGROUND Glioblastoma (GBM) is the most frequently diagnosed malignant brain tumor in adults. GBM is usually lethal within 24 months of diagnosis, despite aggressive multimodality treatment. Although it has been established that cancer-related inflammation is associated with worse outcomes, the role of eosinophils, basophils, atopy, and allergy in glioma biology is only gradually being delineated. In this study, we aimed to examine if eosinophil-based and basophil-based indices were altered in patients with GBM compared with healthy controls. We also aimed to study if there was any correlation between these indices and patient-related and tumor-related factors and survival. METHODS This study was a retrospective analysis of prospectively maintained databases. Data pertaining to patient-related and tumor-related factors, hemograms, and survival data were obtained from the electronic medical records of selected patients. Correlations between eosinophil-based and basophil-based indices and these factors were studied, as was the association with overall survival. RESULTS All the indices were altered in patients with GBM compared with normal healthy controls. The absolute eosinophil count was higher and the neutrophils/eosinophils ratio was lower in the better prognosis groups: those with better performance status; those without features of increased intracranial pressure or altered sensorium at presentation; those with ATRX-retained tumors that did not overexpress p53; and in the long-term survivors. The total lymphocyte count/basophils ratio and the absolute eosinophil count both independently predicted survival in a multivariate analysis. CONCLUSIONS The absolute eosinophil count was consistently higher in the better prognosis groups and is likely to be incorporated into prognostic models for GBM.

Abstract
Objective Radiotherapy (RT) and chemotherapy (CT) are important treatment options in patients with head and neck cancers. A common complication of this is microbial colonization or infection of mucosal surfaces. These infections may commonly be due to bacteria or yeasts. Salivary proteins with their buffering activity and immunoglobulin, especially immunoglobulin A (IgA), protect oral tissue, mucosal surfaces, and teeth from various microorganisms. This study characterizes the common microorganisms encountered and evaluates the role of salivary IgA in predicting microbial infections in this group of patients with mucositis.
Methods A total of 150 adult head and neck cancer patients on CTRT were evaluated at baseline and at the end of 3 and 6 weeks, respectively. Oral swabs collected from buccal mucosa were processed in the microbiology laboratory for the presence of microorganisms. Saliva was processed for IgA level estimation on Siemens Dimension Automated biochemistry analyzer.
Results Pseudomonas aeruginosa and Klebsiella pneumoniae were the most common organisms found in our patients, followed by Escherichia coli and group A beta-hemolytic Streptococci. A significant increase (p = 0.0203) in the incidence of bacterial infection was observed in post-CTRT patients (61%) compared to pre-CTRT patients (49.33%). There was significant increase in levels of salivary IgA (p = 0.003) in patients with bacterial and fungal infection (n = 135/267) when compared to those in samples showing no growth (n = 66/183).
Conclusion A significant increase in the incidence of bacterial infection in post-CTRT patients was observed in this study. This study also indicated that postoperative head and neck cancer patients with oral mucositis that developed an infection were associated with high salivary IgA levels, and it may serve as a surrogate biomarker of infection in these patients.

Abstract
INTRODUCTION Remote consultation has potential benefits in increasing patient pathway efficiency and has been found to reduce costs and carbon emissions. Previous studies of remote consultation in ear, nose and throat (ENT) practice have reported mixed results and used relatively small sample sizes. The aim of this article is to study the impact of remote telephone consultation on ENT clinic outcomes and pathway efficiency, compared with in-person review, within new and follow-up patient cohorts and subspeciality, where previous studies demonstrate mixed and inconclusive results. METHODS This was a comparison of remote clinic appointment outcomes over a 2-month period from a single ENT referral centre (426) with an equivalent data set of face-to-face clinic appointments over a similar time frame (1,533). Statistical analysis included chi-squared test for clinic outcomes and two-sample t-squared test for mean hand-off between both cohorts (p < 0.05). RESULTS For new referrals, remote consultation was associated with statistically significantly greater rates of follow-up (p < 0.00001), investigation (p = 0.00251) and hand-off (p < 0.00013) than patients seen face-to-face - particularly where presenting with head and neck symptoms. For follow-up patients, remote consultation had similar rates of investigation (p = 0.11071) or further follow-up (p = 0.08) and mean hand-off (p < 0.11764) to those seen face-to-face. CONCLUSIONS Remote consultation in ENT could become the norm for follow-up patients, but should be used with caution in the initial consultation of new patients.

Abstract
Background and Aim Despite recent advances, the outcomes of diffuse intrinsic pontine glioma (DIPG) remain dismal. This is a retrospective study to understand the pattern of care and its impact on DIPG patients diagnosed over 5 years in a single institute. Subjects and Methods DIPGs diagnosed between 2015 and 2019 were retrospectively reviewed to understand the demographics, clinical features, patterns of care, and outcomes. The usage of steroids and response to treatment were analyzed as per the available records and criteria. The re-irradiation cohort was propensity matched with patients with a progression-free survival (PFS) >6 months treated with supportive care alone based on PFS and age as a continuous variable. Survival analysis was performed using the Kaplan-Meier method, and Cox regression model was used to identify any potential prognostic factors. Results One hundred and eighty-four patients were identified with demographic profiles similar to western population-based data in the literature. Of them, 42.4% were residents from outside the state of the institution. About 75.2% of patients completed their first radiotherapy treatment, of which only 5% and 6% had worsening clinical symptoms and persistent need for steroids 1 month posttreatment. On multivariate analysis, Lansky performance status <60 (P = 0.028) and cranial nerve IX and X (P = 0.026) involvement were associated with poor survival outcomes while receiving radiotherapy with better survival (P < 0.001). In the cohort of patients receiving radiotherapy, only re-irradiation (reRT) was associated with improved survival (P = 0.002). Conclusion Many patient families still do not choose radiotherapy treatment, although it has a consistent and significant positive association with survival and steroid usage. reRT further improves outcomes in the selective cohorts. Involvement of cranial nerves IX and X needs improved care.

Abstract
Primary CNS lymphoma (PCNSL) is a rare subtype of non-Hodgkin lymphoma with the worst outcomes amongst all extranodal lymphomas. There is a scarcity of data on real-world outcomes of primary CNS lymphoma (PCNSL) owing to the rarity of the disease. This study analyzed the demographic patterns, risk stratification, treatment regimens used, & outcomes of patients treated at Tata Memorial Center Mumbai, India. This is a retrospective analysis of newly diagnosed primary CNS lymphoma patients treated at our centre over seven years from January 2013 to December 2019. A total of 142 patients with PCNSL were diagnosed during this period. Thirty (21.1%) patients were deemed ineligible for any systemic or local therapies,ten patients were referred to other hospitals, two patients had relapsed disease, and one was excluded because age less than 18 years. Finally 99 patients were included in the final analysis. Among these 99 patients,72 patients (72.7%) were < 60 years,70 (70.7%) patients had Eastern cooperative oncology group (ECOG) performance status (PS) less than equal to 2. DLBCL was the most common histology (86.4%) while rests were high grade B cell NHL NOS (11.4%),Burkitt's Lymphoma(1%),Peripheral T-cell Lymphoma NOS (1.2%). Only one of 99 patients was positive for HIV serology. Multiple intracranial lesions were found in 59.5%. Surgical resection was performed in 28.4% of patients. Out of 63 patients in whom the International extranodal lymphoma study group (IELSG) score is available, 34(54%) were IELSG high-risk groups. As per Memorial Sloan Kettering Cancer Center (MSKCC) risk grouping, patients were almost equally distributed in all the risk groups, with 32(32.3%) patients in risk group 1 (age < 50 years), 36(36.4%) patients in risk group 2 (age > 50 years, KPS > = 70), and 31(31.3%) patients in risk group 3 age > 50 years, KPS < 70). First-line treatment with high dose methotrexate (HD-MTX) based regimens was administered to 92 (92.9%) patients, and 72.8% of these patients received rituximab. Of these 92 patients, 59 (64.1%) patients could complete induction, and 52 patients received consolidation. Thirty-one patients received high dose cytarabine based chemo consolidation, one patient underwent high dose chemotherapy followed by autologous stem cell transplantation (ACST), and 19 patients received whole-brain radiotherapy (WBRT) and 1 patient received temozolomide as consolidation regimen. Thus only 52 patients completed the entire course of induction with consolidation therapy. The response to treatment was assessed using International PCNSL Collaborative Group Criteria. Post completion of consolidation, 49(94.2%) patients had a complete response. With a median follow-up duration of 39.2 months, the median progression-free survival (PFS) and the median overall survival (OS) of the patients taken into the analysis (N = 99) were 21 and 37 months respectively. On multivariate analysis, age < 60 yrs, > = 5 HD-MTX cycles received & the use of rituximab predicted better OS.Outcomes of patients with PCNSL treated with HD-MTX based therapy are comparable to reported literature however a large proportion of patients do not undergo required treatment despite the curable nature of disease.

Abstract
Background Contemporary standard-of-care for newly diagnosed glioblastoma (GBM) is maximal safe resection followed by postoperative focal conformal radiotherapy (RT) plus concurrent temozolomide (TMZ) and 6-cycles of adjuvant TMZ (Stupp regimen). However, many patients continue to receive extended adjuvant TMZ (beyond 6-cycles) without solid scientific evidence. This review pools data from nonrandomized studies and randomized controlled trials (RCTs) comparing extended adjuvant TMZ (>6-cycles) to standard adjuvant TMZ (6-cycles) in patients with newly diagnosed GBM for updated evidence-synthesis. Methods This systematic review and meta-analysis was carried out in accordance with the Cochrane methodology including quality assessment of primary studies. Primary outcome of interest was comparative efficacy defined as progression-free survival (PFS) and overall survival (OS). Hazard ratios (HRs) for PFS and OS with corresponding 95% confidence interval (CIs) were extracted/computed from individual primary studies and pooled using random-effects model. Any p-value <0.05 was considered statistically significant. Results Evidence-synthesis was based on pooling of data from 2578 patients enrolled in 16 nonrandomized comparative studies and 5 RCTs. Overall, extended adjuvant TMZ was associated with statistically significant reduction in the risk of progression (HR = 0.72, 95%CI: 0.60-0.87; p = 0.007) and death (HR = 0.71, 95%CI: 0.57-0.90; p = 0.004) compared to standard adjuvant TMZ. However, on subgroup analysis, survival benefit of extended adjuvant TMZ was limited to data synthesized from retrospective nonrandomized comparative studies with no statistically significant difference in outcomes seen after pooling of data from RCTs only. Conclusion Apparent survival benefit of extended adjuvant TMZ in newly diagnosed GBM is largely driven by nonrandomized comparative studies with high inherent potential for multiple biases.

Abstract
Purpose and background: Isocitrate dehydrogenase (IDH) mutation and O-6 methyl guanine methyl transferase (MGMT) methylation are surrogate biomarkers of improved survival in gliomas. This study aims at studying the ability of semantic magnetic resonance imaging (MRI) features to predict the IDH mutation status confirmed by the gold standard molecular tests. Methods: The MRI of 148 patients were reviewed for various imaging parameters based on the Visually AcceSAble Rembrandt Images (VASARI) study. Their IDH status was determined using immunohistochemistry (IHC). Fisher’s exact or chi-square tests for univariate and logistic regression for multivariate analysis were used. Results: Parameters such as mild and patchy enhancement, minimal edema, necrosis < 25%, presence of cysts, and less rCBV (relative cerebral blood volume) correlated with IDH mutation. The median age of IDH-mutant and IDH-wild patients were 34 years (IQR: 29−43) and 52 years (IQR: 45−59), respectively. Mild to moderate enhancement was observed in 15/19 IDH-mutant patients (79%), while 99/129 IDH-wildtype (77%) had severe enhancement (p-value <0.001). The volume of edema with respect to tumor volume distinguished IDH-mutants from wild phenotypes (peritumoral edema volume < tumor volume was associated with higher IDH-mutant phenotypes; p-value < 0.025). IDH-mutant patients had a median rCBV value of 1.8 (IQR: 1.4−2.0), while for IDH-wild phenotypes, it was 2.6 (IQR: 1.9−3.5) {p-value = 0.001}. On multivariate analysis, a cut-off of 25% necrosis was able to differentiate IDH-mutant from IDH-wildtype (p-value < 0.001), and a cut-off rCBV of 2.0 could differentiate IDH-mutant from IDH-wild phenotypes (p-value < 0.007). Conclusion: Semantic imaging features could reliably predict the IDH mutation status in high-grade gliomas. Presurgical prediction of IDH mutation status could help the treating oncologist to tailor the adjuvant therapy or use novel IDH inhibitors.

Abstract
Loneliness is the pain of feeling socially isolated from others (Russell et al., 1980). The Stress-Dampening Hypothesis (Marlatt, 1987; Sayette, 1993; Sher, 1987) posits that individuals drink to alleviate negative affect. To date, it has not been determined whether loneliness experienced as a child can indirectly influence at-risk patterns of alcohol use through the mediating mechanism of stress and impaired control. Impaired control over alcohol use (IC) is the difficulty adhering to one's own self-proscribed limits on drinking behaviors (Heather et al., 1993). Impaired control is an at-risk pattern of use that is particularly relevant to emerging adults. Methods: We examined the direct and indirect relationships between childhood loneliness, stress, IC, and alcohol-related problems with a structural equation model. In a college student sample, we utilized a (k = 20,000) bootstrap technique and a model indirect command in Mplus to examine potential mediational pathways. Cisgender sex was included as a covariate. Results: Loneliness was directly linked to stress as well as to alcohol-related problems. Higher levels of loneliness were indirectly linked to both more alcohol use and alcohol-related problems through more stress and in turn, more impaired control over drinking. Conclusions: The current study is consistent with the Stress Dampening Hypothesis (Marlatt, 1987; Sayette, 1993; Sher, 1987). Our findings suggest that therapeutic interventions combating loneliness in childhood may disrupt the stress-dampening pathway to dysregulated alcohol use in emerging adulthood.

Abstract
Abstract
INTRODUCTION
In patients treated with radiation (RT), doses to hippocampus influence neurocognitive outcomes. However, the role of hippocampal subvolumes in memory functioning has not been reported, which prompted the current study.
METHODS
Adults ( > 18 years) with pituitary tumors treated with fractionated RT (45 Gy/ 25 fractions/ 5 weeks) were accrued in the prospective study. Hippocampus was delineated on T1-weighted 3D-FSPGR sequences with 1mm slice thickness. The head, body, and tail of hippocampus were drawn for the current study based on the consensus of two neuroradiologists. The anatomical landmarks were: head (basilar artery to interpeduncular cistern), body (interpeduncular cistern to superior colliculus), and tail (beyond superior colliculus). Memory assessment was done pre-RT and 18 months post-RT by dedicated neuropsychologist using Weschler Memory Scale. The dose-volume parameters (maximum, mean, D10-D100) were extracted from bilateral hippocampus and subvolumes individually, which were correlated with the memory outcomes. Binary endpoints of > 5% drop of memory quotient (MQ) or not at 18 months were used for analysis using an independent t-test or Mann Whitney test as appropriate.
RESULTS
Of 25 patients included in the analysis, 11 had drop of MQ > 5% at 18 months. The left and right hippocampus doses of D10, D20, and D30 were significantly higher in patients with higher memory decline. For the subvolumes, only dose to bilateral head had statistically significant impact on MQ. Mean doses for patients with > 5% MQ drop for left and right heads were 26 Gy and 24 Gy compared to 21 Gy and 19 Gy, respectively, for the other group.
CONCLUSION
Doses to bilateral hippocampus were shown to impact short-term memory. Of the subvolumes, only head appeared significant in memory functioning from the current pilot study, opening a window for exploring stricter dose constraints towards hippocampal head for primary or metastatic brain tumors.

Abstract
Abstract
Purpose/Objective(s)
Re-irradiation (ReRT) is often used to treat recurrent high grade glioma (HGG). There is limited literature regarding the patterns of recurrence following ReRT, which was investigated in the current study.
Materials/METHODS
Patients with available radiation (RT) contours, dosimetry, and imaging-based evidence of recurrence were included in the retrospective study. All patients were treated with fractionated RT using conformal technique. Recurrence was documented as per decision in tumor board based on imaging with magnetic resonance imaging (MRI) or Flouroethyl-L-Tyrosine (FET) positron emission tomography (PET), which was registered with the planning CT. Failure patterns were classified as in-field, marginal, and out-field as decided by >50% recurrence volume within 95%, 20-95%, and outside 20% isodose lines, respectively.
RESULTS
Study population included 37 patients treated with median dose of 54 Gy (range 50.4-54 Gy). Before ReRT, 92% patients had undergone surgery (biopsy in 3, gross total resection in 9, subtotal resection in 22), 62% received concurrent chemo with ReRT, and 49% received maintenance chemotherapy. Median time to recurrence was 9 months (7-16 months, median 10 and 8 months respectively for in-field and marginal/out-field recurrence). In-field, marginal, and out-field recurrence were seen in 24 (65%), 10 (27%), and 3 (8%), respectively. Recurrence mapping was done using MRI, PET, or both in 27, 3, and 7, respectively. Of 24 patients with in-field recurrence, 8 and 16 had disease volume within gross tumor volume and clinical target volume, respectively. 2 patients had leptomeningeal dissemination (1 with majority of recurrence volume in-field and 1 with marginal failure in addition to metastatic disease).
CONCLUSION
Following ReRT for HGG, the majority of recurrence was in the high dose region, suggesting the use of conservative target volumes. Future studies are required for feasibility of dose-escalation to improve control rates, particularly in patients with long intervals from first course of RT.

Abstract
INTRODUCTION
Little is known about tumour-infiltrating lymphocytes (TILs) in brain metastasis (BM) and their utility as predictive biomarker for immunotherapy. AIM: To analyze TILs in BM, and correlate with corresponding paired primary (PP).
METHODS
Inclusion: Histologically confirmed BM and PP (2015-2020). Exclusion: Hematological malignancies, spinal cord/meningeal metastasis, pediatric age, slides/blocks not available. Final Nf 277 BM; 64 PP. One H&E slide from both PP &BM assessed for stromal TILs (sTILs) and intratumoral TILs (iTILs) as per International TIL Working Group guidelines.
RESULTS
Median sTILs (10%) were significantly higher than iTILs (1%) in primary and BM (p-value < 0.001). sTILs were mild (<10%) in majority of primary (57.8%) and BM (59.9%), while iTILs were nearly always mild (primary 97.1%; BM 96.9%). Between PP and BM, no change in sTIL category in 48.43%, while conversion in 51.56%, with higher to lower conversion (66.67%) > lower to higher (33.33%). Conversion rate higher for breast (54.3%) &GIT (62.5%) than lung (45.5%) &GUT (40%). In BM, preoperative steroid therapy (PST) showed lower sTILs (≤10%) (p-value= 0.041), and adenocarcinoma histology higher sTILs ( >10%) (p-value= 0.001), while precocious metastasis (p-value= 0.051) and absence of extracranial metastasis (p-value= 0.083) trended towards higher sTILs. Median survival of whole cohort was 20 months (95% CI 14.4-25.68 months). Presence of extracranial metastasis (p-value= 0.01); precocious BM (p-value= 0.007) showed lower overall survival (OS), while adenocarcinoma histology better OS (p-value= 0.029), in both univariate and multivariate analysis. Absence of PST showed longer median survival, though not significant (24.1 vs 19.8months; p-value= 0.19).
CONCLUSIONS
sTILs predominantly show high >low conversion between PP and BM, signifying lowered immune response in BM. Thus, evaluation of sTILs in BM, wherever tissue available, may be indicated if immunotherapy is considered. Parameters with higher sTILs showed longer survival, possibly indicating prognostic role of tumor microenvironment in BM.

Abstract
Abstract
BACKGROUND AND PURPOSE
Differentiating tumor recurrence (TR) from radiation necrosis (RN) in high grade glioma (HGG) following radiotherapy can be challenging. The ability of conventional magnetic resonance imaging (MRI) to differentiate TR from post-therapeutic effects is often limited. Multiparametric advanced MRI (perfusion) and positron emission tomography (PET) with amino acid tracers, specifically 18F-Fluoroethyl-Tyrosine (FET) can provide relevant additional information on tumor metabolism, which allows for a more accurate diagnosis to differentiate tumor recurrence from radiation necrosis in high grade gliomas.
MATERIALS AND METHODS
Prospective analysis of 62 lesions in 62 patients with HGG who underwent both MRI and FET-PET imaging within three weeks intervals was done independently by a neuroradiologist and nuclear medicine physician. The study was conducted in a tertiary care oncology center between July 2018 and August 2021. Manually segmented regions of interest were placed over the areas of maximum enhancement/suspicion on MRI and FET uptake, which were used to calculate the relative cerebral volume (rCBV) and tumor to background ratios, respectively. Definitive diagnosis (TR versus RN) was made on clinico-radiological follow-up or histopathological report (wherever available).
RESULTS
Out of the 62 lesions that were studied, 46 and 16 had TR and RN, respectively. The sensitivity and specificity for determination of TR in HGG with conventional MRI were 98% and 62.5% respectively, while with FET-PET it was 91% and 87.5% respectively. The PPV , NPV and accuracy for MRI were 88%, 91% , 89% , while for FET-PET it was 95%, 78% and 90% respectively. A combination of MRI and PET parameters (mean target-to-background ratio), demonstrated an increase in diagnostic accuracy to 97%.
CONCLUSION
Cumulative imaging with MRI and FET-PET offers a multiparametric assessment of glioma recurrence that is correlative and complimentary, with higher accuracy and clinical value.

Abstract
PURPOSE Medulloblastoma is a heterogenous disease comprising four molecular subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4, respectively. Excellent long-term outcomes have prompted deintensification of therapy in WNT-pathway medulloblastoma. We assessed the safety of avoiding upfront craniospinal irradiation (CSI) in children with low-risk WNT-pathway medulloblastoma. PATIENTS AND METHODS Children with low-risk WNT-pathway medulloblastoma were treated with postoperative focal conformal radiotherapy, avoiding upfront CSI, followed by six cycles of adjuvant systemic chemotherapy. A group-sequential design (triangular test) with predefined stopping rules if the rate of relapse exceeded 15% at 2 years was incorporated to ensure the safety of study participants. RESULTS 7 children with low-risk WNT-pathway medulloblastoma were accrued after written informed consent/assent and treated as per protocol. One child died of neutropenic sepsis and multiorgan dysfunction during chemotherapy. Three children were detected with neuraxial failure (supratentorial brain and/or spine) on surveillance neuro-imaging within 2 years from index diagnosis, leading to premature study termination. At relapse, children were treated with salvage CSI plus boost irradiation of metastatic deposits followed by second-line chemotherapy. Two of them continue to be in remission (32 and 26 months after first relapse), while one child developed a second relapse, necessitating further systemic chemotherapy and craniospinal reirradiation, resulting in excellent clinico-radiologic response. At a median follow-up of 42 months, the 2-year Kaplan-Meier estimates of event-free survival, recurrence-free survival, and overall survival were 42.9%, 50%, and 85.7% respectively. CONCLUSIONS Omission of upfront CSI in low-risk WNT-pathway medulloblastoma is associated with an unacceptably high risk of neuraxial failure. See related commentary by Remke and Ramaswamy, p. 4161.

Abstract
Background and purposeSemantic imaging features have been used for molecular subclassification of high-grade gliomas. Radiomics-based prediction of molecular subgroups has the potential to strategize and individualize therapy. Using MRI texture features, we propose to distinguish between IDH wild type and IDH mutant type high grade gliomas.MethodsBetween 2013 and 2020, 100 patients were retrospectively analyzed for the radiomics study. Immunohistochemistry of the pathological specimen was used to initially identify patients for the IDH mutant/wild phenotype and was then confirmed by Sanger’s sequencing. Image texture analysis was performed on contrast-enhanced T1 (T1C) and T2 weighted (T2W) MR images. Manual segmentation was performed on MR image slices followed by single-slice multiple sampling image augmentation. Both whole tumor multislice segmentation and single-slice multiple sampling approaches were used to arrive at the best model. Radiomic features were extracted, which included first-order features, second-order (GLCM—Grey level co-occurrence matrix), and shape features. Feature enrichment was done using LASSO (Least Absolute Shrinkage and Selection Operator) regression, followed by radiomic classification using Support Vector Machine (SVM) and a 10-fold cross-validation strategy for model development. The area under the Receiver Operator Characteristic (ROC) curve and predictive accuracy were used as diagnostic metrics to evaluate the model to classify IDH mutant and wild-type subgroups.ResultsMultislice analysis resulted in a better model compared to the single-slice multiple-sampling approach. A total of 164 MR-based texture features were extracted, out of which LASSO regression identified 14 distinctive GLCM features for the endpoint, which were used for further model development. The best model was achieved by using combined T1C and T2W MR images using a Quadratic Support Vector Machine Classifier and a 10-fold internal cross-validation approach, which demonstrated a predictive accuracy of 89% with an AUC of 0.89 for each IDH mutant and IDH wild subgroup.ConclusionA machine learning classifier of radiomic features extracted from multiparametric MRI images (T1C and T2w) provides important diagnostic information for the non-invasive prediction of the IDH mutant or wild-type phenotype of high-grade gliomas and may have potential use in either escalating or de-escalating adjuvant therapy for gliomas or for using targeted agents in the future.

Abstract
BACKGROUND This pilot survey aims to provide an insight into the variations of corticosteroid prescription among health care professionals across the Indian subcontinent and serve as a prerequisite for the future development of corticosteroid therapy guidelines in brain tumor patients. MATERIALS AND METHODS Participants of this anonymized online questionnaire-based survey included health care professionals involved in treating brain tumor patients. Unique links were electronically mailed to health care professionals from a database populated from professional associations. Descriptive statistical analysis, Chi-square test, and/or exact test were used for data analysis. RESULTS Seventy-three percent of the respondents were radiation oncologists followed by neurosurgeons (23%), medical oncologists (2%), and other specialties (2%). Raised intracranial pressure (90%) was the commonest indication for prescribing corticosteroids. Fifty percent of neurosurgeons preferred corticosteroids to be given routinely for all patients undergoing surgery for brain tumors while 64% of the radiation oncologists would prescribe based on imaging findings and/or on appearance of neurologic symptoms. Most of the respondents (90%) used a flat dosage pattern for determining the starting dose of corticosteroids. Emerging data about the long-term use of corticosteroids having a negative impact on the survival of brain tumor patients were not known by 52% of the respondents. The majority of the practitioners (94%) agreed regarding the formulation of evidence-based guidelines for prescribing corticosteroids in brain tumor patients. CONCLUSION In view of the wide variations of corticosteroid therapy practices among health care professionals across various parts of the world, our pilot survey provides significant information which can act as a suitable benchmark to form uniform practice guidelines.

Abstract
Abstract
We report the case of a rare cause of bowel obstruction in a 12-year-old girl who presented with a short history of abdominal distension and vomiting after a month of unexplained urinary frequency and weight loss. Abdominal radiographs demonstrated small bowel obstruction with an unknown pelvic mass. A raised CA125 suggested a possible ovarian lesion and a magnetic resonance scan was interpreted as supportive of this pathology. Intra-operatively a 120x90x70mm cystic mass was found attached to the caecal serosa, immediately adjacent to the ileocaecal valve. There was an associated 180-degree twist of the terminal ileum and ascending colon. A limited right hemicolectomy was performed, and histopathology confirmed the diagnosis of a caecal intestinal duplication cyst. Post-operatively she has recovered well, with resolution of her obstructive and urinary symptoms. Given the unusual age of presentation, uncommon location of the cyst and the diagnostic challenges incurred, the authors wish to share their experience of managing an atypical duplication cyst.

Abstract
BACKGROUND Adult diffuse high-grade gliomas (HGG) predominantly recur locally despite adequate treatment. At recurrence, salvage chemo-reirradiation (CTRT) provides durable local control with significant risk of symptomatic radionecrosis (RN). Reirradiation (reRT) is delivered using either conventional fractionation (CFRT) or hypofractionation based on institutional preferences. Studies have shown that the addition of bevacizumab, a monoclonal antibody inhibiting vascular endothelial growth factor to reRT reduces the risk of RN and potentially improves survival, providing strong scientific rationale for the combination. OBJECTIVE Primary endpoint would be a composite endpoint of 1-year event-free survival (EFS) comprising recurrence, symptomatic RN or death as an event. Secondary endpoints include progression-free survival, cumulative incidence of symptomatic RN, and overall survival. Quality-of-life assessment and health-economics would be tertiary endpoints. METHODS Target population includes adults with local recurrence (radiology and/or histology) of biopsy-proven diffuse HGG >2-years from primary RT. This is an open-label, phase III randomised control trial using a 2 x 2 factorial design comparing the addition of bevacizumab to chemo-reirradiation (test arm) versus chemo-reirradiation alone (control arm) using a superiority hypothesis. Patients in test arm will receive 6 months of bevacizumab (5mg/kg) 2 weekly, along with standard 6 cycles of temozolomide, starting 1 month following reRT completion. All patients will be further randomized to CFRT (50.4-55.8Gy/28-31/5.5-6 weeks) as control arm versus moderately HFRT (35Gy/10 fractions/2 weeks) as test arm in 1:1 ratio using a non-inferiority hypothesis. The desired sample size is 257 (two-sided alpha 0.05, power 80%, and 10% attrition rate) with a superiority hypothesis of 1-year EFS 45% (bevacizumab with CTRT) vs 30% (CTRT), and non-inferiority hypothesis of 25% (HFRT) vs 37% (CFRT),with delta of 12%. DISCUSSION The study will answer critical questions regarding the role of bevacizumab in recurrent HGG along with reRT, along with the differences in outcomes using normofractionated or hypofractionated RT.

Abstract
Abstract
BACKGROUND
Surgery is indicated for large or symptomatic lesions in patients with limited brain metastasis (BM), followed by adjuvant stereotactic radiosurgery (A-SRS) to the cavity. Emerging evidence suggests promising role of neoadjuvant SRS (NA-SRS) before surgery with potentially lesser risk of leptomeningeal disease (LMD) and radionecrosis (RN). Hippocampal avoidance whole brain radiotherapy (HA-WBRT) results in better neurocognitive outcomes than standard WBRT, and use of simultaneous integrated boost (SIB) to surgical cavity can improve the local control. Absence of high-quality evidence forms the basis of current study comparing these three treatment strategies.
OBJECTIVES
Primary endpoint is 1-year event-free survival (EFS) a composite endpoint comprising any local failure, LMD, DBF, symptomatic RN, or death as events. Other endpoints include individual endpoints and longitudinal neuro-cognitive function and quality-of-life assessment.
METHODS
Target population includes adults with newly diagnosed BM (≤3 lesions) with life expectancy >1 year and one target lesion needing surgery. Patients will be randomized (1:1:1) to A-SRS (control arm) or one of two test arms (NA-SRS or HA-WBRT-SIB). In A-SRS arm, patients will receive single fraction (16-20Gy) or hypofractionated-SRS (24-27Gy/3 fractions or 30-32.5Gy/5 fractions) based on volume and location of cavity and other intact BM. In the test arms, patients will be allocated to either NA-SRS group (single/multi-fraction) followed by surgery within 2 weeks or HA-WBRT (30Gy/10 fractions) with SIB to cavity plus other intact BM (40-50Gy/10 fractions) combined with memantine within 6 weeks of surgery. A sample size of 168 patients is required to prove the superiority of test arms individually compared to the control arm with assumption of 1-year EFS of 43% versus 25% with a hazard ratio of 0.6 (two-sided alpha=0.05, power=80%, and 15% attrition rate).
DISCUSSION
The study will generate level 1 evidence investigating the role of NA-SRS or HA-WBRT-SIB compared to A-SRS in limited brain metastases.

Abstract
PURPOSE Delivery of cancer care during the pandemic required adopting various changes in the standard management. We analyzed the impact of the first wave of the COVID-19 pandemic on radiation oncology treatment practices at Tata Memorial Hospital in India. MATERIALS AND METHODS From March 1 to October 31, 2020, all consecutive patients who attended the radiation oncology department for radiotherapy treatment were included in this study. Electronic medical records, patient files, and telephonic consult were used to collect patient's data including changes in the standard treatment practice, COVID-19 testing and its results, and subsequent impact on radiotherapy treatment. Comparison was done with the same period data of 2019 for the number of the caseload, radiotherapy regimen, referral rates, and noncompliance rates. RESULTS Our study included 4,256 patients with a median age of 52 years (interquartile range 41-61 years). There was a significant drop in the new-patient registrations (approximately 63%), radiotherapy consultations (44.9%), and referrals to other centers (27.8%). The reduction in the caseload was highest for genitourinary cases (–58.5%) and the lowest for breast cases (–11.5%) when compared with the 2019 cohort. Among those treated with radical intent, the noncompliance rate was 15%. Hypofractionation was the commonly adopted regimen across all sites. Compared with 2019, the maximum reduction in the average fractions per patient was seen in the breast cancer cases (–8.2 fraction), followed by genitourinary cases (–4.9 fraction). Of the 27.8% of patients tested for COVID-19, 13.4% turned positive and 3.4% died due to the disease. CONCLUSION The COVID-19 pandemic adversely affected the number of radiotherapy consultations and treatments at our institute. However, our department offered uninterrupted services despite grave challenges. Hypofractionated regimen was used across disease sites to minimize patient visits and allow planned treatment completion. Radiotherapy was delivered safely, and patients experienced low rates of COVID positivity during radiotherapy and even lower mortality.
