Abstract
Adjuvant radiotherapy is an integral component in the management of soft-tissue sarcomas. Brachytherapy is a very convenient and conformal way of delivering adjuvant radiotherapy in such tumours, which spares the surrounding normal tissue. Randomised studies have established the efficacy of brachytherapy in the adjuvant setting, with a 5-year local control of 80-85%. High dose rate, low dose rate and pulsed dose rate have shown equivalent local control, but high dose rate has gained popularity owing to patient convenience, radiation safety and flexibility in dose optimisation. Freehand insertion perioperative brachytherapy (intraoperative placement and postoperative treatment) is the most commonly used technique in soft-tissue sarcomas, with intraoperative radiotherapy and radioactive seed placement being the less commonly used techniques. Brachytherapy can be used as monotherapy or in combination with external beam radiotherapy, such as in cases of close/positive margins for safe dose escalation. Although the quantum of side-effects with external beam radiotherapy has considerably reduced with the evolution of technology and the introduction of intensity modulation (intensity-modulated radiotherapy), brachytherapy still scores better in terms of dose conformality, especially in recurrent tumours (previously irradiated) and when used to treat paediatric and geriatric patients.

Abstract
PURPOSE Our aim was to assess the effect of radiation therapy (RT) dose escalation on outcomes in surgically unresectable Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET). METHODS AND MATERIALS Patients with nonmetastatic unresectable ES/PNET (excluding intracranial/chest wall) receiving vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide chemotherapy, planned for definitive RT, were accrued in this single-institution, open-label, phase 3 randomized controlled trial. Randomization was between standard dose RT (SDRT; 55.8 Gy/31 fractions/5 days a week) versus escalated dose RT (EDRT; 70.2 Gy/39 fractions/5 days a week) with a primary objective of improving local control (LC) by 17% (65%-82%). Secondary outcomes included disease-free survival (DFS), overall survival (OS), and functional outcomes by Musculoskeletal Tumor Society score. RESULTS Between April 2005 and December 2015, 95 patients (SDRT 47 and EDRT 48) with a median age of 17 years (interquartile range, 13-23 years) were accrued. The majority of patients were male (59%). Pelvis was the most common site of primary disease (n = 60; 63%). The median largest tumor dimension (9.7 cm) and the median maximum standardized uptake value (8.2) on pretreatment fluorodeoxyglucose positron emission tomography-computed tomography were similar. At a median follow-up of 67 months, the 5-year LC, DFS, and OS for the entire cohort was 62.4%, 41.3%, and 51.9%, respectively. The 5-year LC was significantly better in EDRT compared with SDRT (76.4% vs 49.4%; P = .02). The differences in DFS and OS at 5 years (for EDRT vs SDRT) did not achieve statistical significance (DFS 46.7% vs 31.8%; P = .22 and OS 58.8% vs 45.4%; P = .08). There was a higher incidence of Radiation Therapy Oncology Group grade >2 skin toxic effects (acute) in the EDRT arm (10.4% vs 2.1%; P = .08) with excellent functional outcomes (median Musculoskeletal Tumor Society score = 29) in both arms. CONCLUSIONS EDRT results in improved LC with good functional outcomes without a significant increase in toxic effects. Radiation dose escalation should be considered for surgically unresectable nonmetastatic ES/PNET.

Abstract
BACKGROUND There is lack of consensus regarding optimal adjuvant therapy in elderly glioblastoma (GBM). We have been treating elderly (≥60 years) GBM patients with normofractionated or hypofractionated radiotherapy (RT) plus temozolomide (TMZ) based on Karnofsky performance status (KPS). Herein we report clinical outcomes in this cohort treated at our institute using this approach. METHODS Medical records of elderly GBM patients (≥60 years) treated between 2013 and 2017 with either normofractionated RT (59.4-60 Gy/30-33 fractions/6-6.5 weeks) or hypofractionated RT (35 Gy/10 fractions/2 weeks) plus TMZ were reviewed retrospectively. Outcomes of interest included progression-free survival (PFS), overall survival (OS), and ≥grade 3 myelotoxicity. Time-to-event outcomes were analyzed with Kaplan-Meier methods, compared using log-rank test, and reported as point estimates with 95% confidence interval (CI). RESULTS The normofractionated cohort (n = 126) was characterized by a higher proportion of patients younger than age 65 years, KPS ≥70, methylated O6-methylguanine DNA methyltransferase (MGMT), and receiving adjuvant TMZ including extended adjuvant TMZ (>6 cycles) compared with the hypofractionated cohort (n = 20), confirming selection bias. At a median follow-up of 13 months, 1-year Kaplan-Meier estimates of PFS and OS were 43% (95% CI: 36%-52%) and 56% (95% CI: 48%-64%), yielding median PFS and OS of 11.0 months and 13.1 months, respectively. Higher KPS, methylated MGMT, normofractionated RT, and extended adjuvant TMZ emerged as favorable prognostic factors. TMZ was well tolerated with a low risk of ≥grade 3 myelotoxicity. CONCLUSIONS Our single-institution clinical audit confirms poor survival in elderly GBM with suboptimal performance status but demonstrates acceptably fair outcomes in patients with preserved KPS comparable with the nonelderly cohort.

Abstract
BACKGROUND & PURPOSE To evaluate the efficacy and toxicity of dose-escalated image guided-intensity modulated radiation therapy (IG-IMRT) in osteosarcoma (OGS), chondrosarcoma (CS) and chordoma (CH) of head and neck (H&N) and pelvis. METHODS AND MATERIALS In this prospective non-randomized study, 65 patients of H&N or pelvic OGS (24), CS (7) and CH (34) mandating definitive or post-operative radiotherapy from May 2013 to December 2018 were included. Radiotherapy doses in definitive setting were 72.0 Gy for CH and 70.2 Gy for OGS and CS; while in post-operative setting it was 66.6 Gy and 64.8 Gy respectively (at 1.8 Gy per fraction). RESULTS Planned doses of radiotherapy could be completed in 61 (93.8%) patients; with grade III or higher acute and late toxicities of 3% and 0% respectively. With a median follow-up of 52 (range 6-92) months, the five-year actuarial local control (LC) rates were 66% in OGS, 38.1% in CS and 75.9% in CH; while cause-specific survival (CSS) rates were 54.7%, 64.3% and 92.2% respectively. There was no statistically significant difference in outcomes for patients receiving definitive and post-operative radiotherapy. Locally controlled disease at first follow-up after radiotherapy was associated with improved CSS and OS in CS (p = 0.014) and CH (p < 0.001). Radiotherapy resulted in significant and sustained improvement in Musculoskeletal tumour society (MSTS) score and reduction in pain score. Salvage re-irradiation was feasible in local progression after radiotherapy, with good outcomes and tolerability. CONCLUSION Dose-escalated IG-IMRT results in good LC & functional improvement with minimal toxicity in OGS, CS and CH.

Abstract
BACKGROUND We present our institutional approach for re-irradiation in diffuse intrinsic pontine glioma and their outcomes. METHODS Consecutive patients of recurrent diffuse intrinsic pontine glioma treated with re-irradiation (January 2015-September 2019) were reviewed retrospectively to describe the clinical-response-based approach followed for the dose and volume decision. Outcomes were defined with clinical and steroid response criteria and survival endpoints included progression-free survival and overall survival as cumulative(c) overall survival and re-irradiation overall survival (re-irradiation starting to death). The Kaplan-Meier method and log-rank test were used for survival analysis. RESULTS Twenty-patient cohort with a median (m) age of 7.5 years, m-progression-free survival of 8.4 months and m-Lansky performance score of 50 received re-irradiation of which 17 (85%) were called clinical responders. The median re-irradiation-overall survival with 39.6-41.4, 43.2 and 45 Gy were 5.8, 7 and 5.3 months, respectively. One-month post-re-irradiation steroid independent status was a significant predictor of better survival outcomes (overall survival, P≤0.004). No ≥ grade 3 toxicities were noticed. Two patients succumbed to intra-tumoral hemorrhage. CONCLUSIONS Higher doses of re-irradiation based on a clinical-response-based approach show improvement in survival and steroid dependence rates with acceptable toxicity. Steroid independent status at 1-month post-re-irradiation predicts better outcomes. Prospective studies may validate this with quality of life data.

Abstract
This review aimed to assess diagnostic performance of 18F-flouro-deoxy-glucose positron emission tomography (FDG-PET) with or without computed tomography (CT) scan in primary central nervous system lymphoma (PCNSL). Eligible studies reporting diagnostic accuracy of pretreatment FDG-PET(CT) scan in immunocompetent adults with PCNSL were identified through systematic literature search. Data on diagnostic performance from individual studies was summarized in a 2 × 2 table classifying patients as true positives, true negatives, false positives, and false negatives using histopathologic diagnosis as reference standard. Random-effects model was used to calculate weighted-mean pooled sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic odds ratio with 95% confidence intervals (95% CI). Twenty-nine primary studies involving 967 patients were included. Weighted-mean pooled sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic odds ratio was 87% (95% CI, 83%-90%), 85% (95% CI, 81%-88%), 84% (95% CI, 81%-88%), 87% (95% CI, 84%-90%), and 29.78 (95% CI, 18.34-48.35), respectively, demonstrating acceptably high diagnostic accuracy of pretreatment FDG-PET(CT) scan in immunocompetent patients with PCNSL.

Abstract
PURPOSE We report the patterns of locoregional recurrence (LRR) in muscle invasive bladder cancer (MIBC), and propose a risk stratification to predict LRR for optimizing the indication for adjuvant radiotherapy. MATERIALS AND METHODS The study included patients of urothelial MIBC who underwent radical cystectomy with standard perioperative chemotherapy between 2013 and 2019. Recurrences were classified into local and/or cystectomy bed, regional, systemic, or mixed. For risk stratification modelling, T stage (T2, T3, T4), N stage (N0, N1/2, N3) and lymphovascular invasion (LVI positive or negative) were given differential weightage for each patient. The cohort was divided into low risk (LR), intermediate risk (IR) and high risk (HR) groups based on the cumulative score. RESULTS Of the 317 patients screened, 188 were eligible for the study. Seventy patients (37.2%) received neoadjuvant chemotherapy (NACT) while 128 patients (68.1%) had T3/4 disease and 66 patients (35.1%) had N+ disease. Of the 55 patients (29%) who had a recurrence, 31 (16%) patients had a component of LRR (4% cystectomy bed, 11.5% regional 0.5% locoregional). The median time to LRR was 8.2 (IQR 3.3-18.8) months. The LR, IR and HR groups for LRR based on T, N and LVI had a cumulative incidence of 7.1%, 21.6%, and 35% LRR, respectively. The HR group was defined as T3, N3, LVI positive; T4 N1/2, LVI positive; and T4, N3, any LVI. The odds ratio for LRR was 3.37 (95% CI 1.16-9.73, P = 0.02) and 5.27 (95% CI 1.87-14.84, P = 0.002) for IR and HR respectively, with LR as reference. CONCLUSION LRR is a significant problem post radical cystectomy with a cumulative incidence of 35% in the HR group. The proposed risk stratification model in our study can guide in tailoring adjuvant radiotherapy in MIBC.

Abstract
Background Patient satisfaction has emerged as a yardstick to measure success of healthcare ecosystems. OUTPATSAT-35RT is a questionnaire to assess patient satisfaction on outpatient radiotherapy (RT). However, it is yet to be translated and/or validated in any of the common Indian languages. Methods English version of OUTPATSAT-35RT was pilot tested in 20 patients with working knowledge of English undergoing fractionated radiotherapy. Subsequently, the questionnaire was translated into two Indian vernacular languages (Hindi and Marathi) using standardized methodology. The process included forward translation into vernacular language by two professional translators independently, generating an intermediate version of the questionnaire. The intermediate questionnaire was then back-translated into English by another duo of professional translators and compared with the English version of the original OUTPATSAT-35RT questionnaire for final reconciliation. This was subsequently administered to 20 patients each (fluent in respective vernacular language) for pilot testing. All 60 patients (20 per language) underwent semi-structured interviews for reporting any difficulty encountered during filling and suggesting any corrections/modifications to the questionnaire. Results The pilot testing of the English version of OUTPATSAT-35RT in 20 Indian patients did not reveal any difficulty or suggest corrections/modifications, leading to its successful translation into Hindi and Marathi languages. Pilot testing of the translated questionnaires in 20 patients each (fluent in the respective vernacular language) did not find any major difficulty. No corrections/modifications were suggested by the respondents resulting in adoption of the reconciled vernacular questionnaires as final Hindi and Marathi versions of OUTPATSAT-35RT questionnaire. Conclusion The English version of OUTPATSAT-35RT has been successfully translated into Hindi and Marathi languages using standardized methodology. Its psychometric properties are being tested for validation in a larger Indian cohort.
