Objective Families of children with cancer undergoing treatment during COVID‐19 pandemic represent a vulnerable population for psychological distress and early identification and remedial measures are imperative for wellbeing of both the children and the caregivers. This article reports the results of assessment of psychological distress in primary caregivers of children with cancer undergoing treatment at a tertiary care center. Methods Primary caregivers of children with cancer (≤15 years) taking treatment at our institute during the period of July 2020 to August 2020 were prospectively evaluated for psychological distress using Patient Health Questionnaire‐9 (PHQ‐9) and Generalized Anxiety Disorder‐7 (GAD‐7) tools over a telephonic call. There were 2 cohorts, A and B (50 participants each) depending on whether child was diagnosed with COVID‐19 or not respectively during the study period. Results The assessment tool, PHQ‐9 showed a score of ≥10 in 13% (n = 13) participants (95%CI:7.1%–21.2%) in the entire cohort and in 16% (n = 8, 95%CI:5.8%–26.2%) and 10% (n = 5, 95%CI:1.7%–18.3%) participants in cohort A and cohort B respectively. GAD‐7 showed a score of ≥8 in 18% (n = 18) participants (95%CI:11.0%–27.0%) in the entire cohort and in 20% (n = 10, 95%CI:8.9%–31.1%) and 16% (n = 8, 95%CI:5.8%–26.2%) participants in cohort A and cohort B respectively. All participants were assessed, and supportive psychotherapeutic interventions administered over telephonic call. Conclusions Primary caregivers should be assessed and followed up for psychological distress irrespective of other co‐existing factors. Robust support systems built over time could help withstand the exceptional strain of a major surge during a pandemic.

Objective To report the experience with COVID-19 in children with cancer at the largest tertiary-cancer care and referral center in India. Methods This study is a single tertiary center experience on COVID-19 in children with cancer and continuation of cancer-directed therapy in them. Children ≤ 15 y on active cancer treatment detected with COVID-19 until September 15th, 2020 were prospectively followed up in the study. Patients were managed in accordance with well-laid guidelines. Treatment was continued for children with COVID-19 who were clinically stable and on intensive treatment for various childhood cancers. Results One hundred twenty-two children (median age 8 y; range 1–15 y, male:female 1.7:1) with cancer were diagnosed with COVID-19. Of 118 children, 99 (83.9%), 60 (50.8%), 43 (36.4%), 26 (22.0%), and 6 (5.1%) had RT-PCR positivity at 14, 21, 28, 35, and 60 d from diagnosis of COVID-19, respectively. Scheduled risk-directed intravenous chemotherapy was delivered in 70 (90.9%) of 77 children on active systemic treatment with a median delay of 14 d (range 0–48 d) and no increased toxicities. All-cause mortality rate was 7.4% (n = 9) and COVID-19 related mortality rate was 4.9% (n = 6). One hundred-fifteen (94.2%) children with COVID-19 did not require any form of respiratory support during the course of infection. Conclusions COVID-19 was not a major deterrent for the continuation of active cancer treatment despite persistent RT-PCR positivity. The long-term assessment of treatment adaptations requires further prospective follow-up and real-time addressal.

Background Despite being mandated by cooperative groups, omission of nodal sampling is the most frequent protocol deviation in surgery for Wilms tumor. The stations as well as the number of nodes that should be sampled are not clearly defined resulting in a marked variation in practices among surgeons. We propose a systematic method for nodal sampling intending to reduce interoperator variation. In this study, we have assessed the feasibility and yield of systematic lymph node sampling and also evaluated the factors influencing nodal metastasis. Methods Prospective evaluation of 113 Wilms tumor patients operated at a single tertiary cancer center between 2015 and 2019. All these patients underwent a systematic 5-station nodal sampling. Results Median lymph node yield was 8 and 13.2% (15/113) patients harbored a histologically positive nodal disease. Of the patients with positive nodal disease, interaortocaval nodes had metastasis in 46.7% (n = 7). They represented isolated sites of nodal disease (skip metastases) in 28.6% (n = 4) of patients. Right-sided tumors had more frequent involvement of interaortocaval nodes and skip disease. Tumors with high-risk histology had 12.5 times more odds of harboring nodal disease as compared to low and intermediate-risk histology Wilms tumor. Conclusions The proposed method of systematic station wise sampling provides a template to guide surgeons in performing lymph node harvesting. Interaortocaval nodes sampling should be performed routinely as the incidence of disease at this station is sufficiently high and metastasis may skip hilar nodes. Study of diagnostic test Level III evidence.

Background There is limited data on outcomes in cancer patients with coronavirus disease 2019 (COVID‐19) from lower middle‐income countries (LMICs). Patients and Methods This was an observational study, conducted between 12 April and 10 June 2020 at Tata Memorial centre, Mumbai, in cancer patients undergoing systemic therapy with laboratory confirmed COVID‐19. The objectives were to evaluate cumulative 30‐day all‐cause mortality, COVID‐19 attributable mortality, factors predicting mortality, and time to viral negativity after initial diagnosis. Results Of the 24 660 footfalls and 7043 patients evaluated, 230 patients on active systemic therapy with a median age of 42 (1‐75) years were included. COVID‐19 infection severity, as per WHO criteria, was mild, moderate, and severe in 195 (85%), 11 (5%), and 24 (11%) patients, respectively. Twenty‐three patients (10%) expired during follow‐up, with COVID‐19 attributable mortality seen in 15 patients (6.5%). There were no mortalities in the pediatric cohort of 31 (14%) patients. Advanced stage cancer being treated with palliative intent vs others [30‐day mortality 24%% vs 5%, odds ratio (OR) 5.6, 95% CI 2.28‐13.78, P, COVID‐19 attributable mortality in cancer patients on systemic therapy in LMICs appears lower than published data and slightly more than an unselected patient's cohort. Delayed recovery in terms of SARS COV‐2 negativity is seen in these patients. Treating Cancer remains the priority.

Background and hypothesis Bone and lung are the common sites of metastasis in pediatric round cell tumors and its presence indicates poor outcomes. Staging workup for these malignancies thus includes bone marrow biopsy (BMB) along with evaluation of thorax, and tissue analysis for N MYCN status in neuroblastoma. BMB is an invasive procedure requiring general anesthesia with known disadvantages.With an aim of avoiding an invasive BMB a study was taken up to evaluate efficacy of FDG PET CT in detecting marrow involvement in neuroblastoma and rhabdomyosarcoma at staging. Materials and method Prospective observational study evaluated 83 newly diagnosed treatment naive patients of neuroblastoma (n = 43) and rhabdomyosarcoma (n = 42) who underwent conventional imaging of PETCT with CECT of local region along with a CT thorax and BMB (both iliac crest) done within 1 week. Findings of FDG PETCT were compared with bone marrow histology and accuracy parameters were calculated. Result The overall sensitivity, specificity, accuracy, positive-predictive value (PPV), negative-predictive value (NPV) of FDG PETCT for detection of marrow disease was 100%, 86.1%, 89.4%. 68.9% and 100%, respectively. Subset analysis showed sensitivity, specificity, PPV and NPV of 100%, 66%, 71.4% and 100%, respectively, for neuroblastoma, with rhabdomyosarcoma patients having few events NPV of 100% accuracy of 97.6%. Conclusion FDG PETCT with sensitivity and NPV of 100% can be considered as a first stop imaging and biopsy can be avoided in patients with a negative scan.

Indian studies on EBV in childhood classic Hodgkin Lymphoma (cHL) have mainly analyzed the epidemiology of EBV-positive [EBV(+)HL] or negative HL [EBV(-)HL], with limited data on outcomes. We studied a large cohort of children with intermediate and high-Risk cHL for tumor EBV status and its impact on outcomes retrospectively. Of evaluable 189 patients, 84.7% had EBV(+)HL. Positive status was significantly associated with age ≤ 10 years (

To describe the outcomes of elective cancer surgeries and adverse consequences on the patients and medical staff due to the surgical interventions in children during the Coronavirus Disease 2019 (COVID-19) pandemic.The study included children younger than 15 years who underwent elective cancer surgeries from March 4, 2020 and December 3, 2020.A total of 121 patients (62% male; median age, 3 years) underwent surgery. The surgical procedures included nephrectomies (n = 18), neuroblastoma (n = 26) and soft tissue tumor resections (n = 24) and complex surgical procedures like extended liver resections (n = 2), intra-atrial thrombectomy under cardiopulmonary bypass (n = 2), pancreatoduodenectomy (n = 1), and free microvascular flaps (n = 7). Clavien-Dindo Grade III complications were 5% (n = 6), and there were no postoperative deaths. Preoperative COVID-19 testing was performed in 82% of children, and only 2% showed severe acute respiratory syndrome coronavirus 2 positivity. Postoperatively, 26 children were tested because of specific symptoms and, 6 tested positive for severe acute respiratory syndrome coronavirus 2. Except for a median delay of 23 days in treatment, none of the patients with COVID-19 required critical hospital management. None of the surgical residents or faculty acquired COVID-19, while 4 each medical and support staff were tested positive in the study period.COVID-19 was not a deterrent for continued cancer care, and surgeries could be safely performed adopting universal preventive measures without any added morbidity from COVID-19. Caregivers and centers dealing with childhood cancers can be encouraged to sustain or seek early healthcare.

The current multidisciplinary approach in the treatment of Ewing sarcoma has improved cure rates, with contemporary dose-dense chemotherapy attaining 5-year event-free survival (EFS) of 73% in localized cases. Dose-intense and dose-dense chemotherapy is difficult in the majority of resource-limited settings with limited access to optimal supportive care. We report on patients with Ewing sarcoma treated on EFT-2001, a nondose-dense chemotherapy protocol.A retrospective analysis was conducted of patients (15 years) with Ewing sarcoma treated with curative intent during January 2013-June 2017 with an institutional ethics committee-approved nondose-dense protocol (EFT-2001). Local therapy was planned after 9-12 weeks of chemotherapy with metastatic sites addressed with radiotherapy. The study assessed outcomes and prognostic factors.We analysed 200 patients with M:F ratio of 1.27:1 and metastases in 41 patients (20.5%). At a median follow up of 41.5 months (range 4.5-81.8 months), respective 3-year EFS and overall survival (OS) of the whole cohort is 65.3% (95% confidence interval [CI]: 58.1-71.7%) and 79.3% (95% CI: 72.8-84.5%); for localized and metastatic cohort, 70.9% (95% CI: 62.9-77.5%) and 82.8% (95% CI: 75.7-89.0%); and for metastatic cohort, 42.8% (95% CI: 28.0-58.6%) and 65.3% (95% CI: 47.7-78.3%). Presence of residual disease (morphologic/metabolic) on positron emission tomography-computed tomography scan done 3 months post definitive radiotherapy (hazard ratio [HR] 7.92 [95% CI: 3.46-18.14]) and delay in any form of local control4 months (HR 3.42 [95% CI: 1.32-8.89]) affected outcomes. Nonrelapse mortality during treatment was 6.5%, mainly due to cardiomyopathy (3.0%) and bacterial sepsis (1.5%). Cardiotoxicity was seen in 11.5% of patients.Nondose-dense chemotherapy provides good outcomes with manageable toxicities in a multidisciplinary treatment approach, while reducing cumulative drug exposures in the developing world where dose-intense or dose-dense chemotherapy could potentially increase toxicity, and hence seems a feasible approach in resource-limited settings. Presence of any residual disease post definitive radiotherapy or delay in local control portends poor outcome.

BACKGROUND Classical Hodgkin lymphoma (cHL) has excellent survival rates, but late effects are an issue and dictate modern approaches. We analyzed the clinical profile and outcome of cHL treated on a risk-adapted approach aimed at reducing late effects while improving historical outcomes at our center. PROCEDURE Children (≤15 years) consecutively treated for cHL from January 2013 through December 2016 were retrospectively analyzed. 18 FDG-PET-CT-based staging and response assessment was done after two cycles for early response (ERA) and end of chemotherapy (late-response assessment [LRA]) if not in complete response (CR; Deauville
