RESUMO
Crowded outpatient clinics and common wards in many hospitals in low and middle-income countries predispose children, caregivers, and health care workers to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report on the clinical features and outcomes of 15 children with cancer at our center who tested positive for SARS-CoV-2. Five out of 15 patients were symptomatic, and one patient required intensive care and respiratory support. All the patients in the study have recovered from the SARS-CoV-2 infection without any sequelae and have resumed their cancer treatment.

BACKGROUND: Breakthrough chemotherapy-induced vomiting (CIV) is defined as CIV occurring after adequate antiemetic prophylaxis. Olanzapine and metoclopramide are two drugs recommended for the treatment of breakthrough CIV in children, without adequate evidence. We conducted an open-label, single-center, phase 3 randomized controlled trial comparing the safety and efficacy of olanzapine and metoclopramide for treating breakthrough CIV. PROCEDURE: Children aged 5-18 years who developed breakthrough CIV after receiving highly emetogenic chemotherapy or moderately emetogenic chemotherapy were randomly assigned to the metoclopramide or olanzapine arm. The primary objective of the study was to compare the complete response (CR) rates between patients receiving olanzapine or metoclopramide for treating breakthrough CIV during 72 hours after the administration of the study drug. Secondary objectives were to compare CR rates for nausea and toxicities between the two arms. RESULTS: Eighty patients were analyzed (39 in the olanzapine arm and 41 in the metoclopramide arm). CR rates were significantly higher in the olanzapine arm compared with the metoclopramide arm for vomiting (72% vs 39%, P = 0.003) and nausea (59% vs 34%, P = 0.026). Seven patients in the metoclopramide arm crossed over to the olanzapine arm and none crossed over in the olanzapine arm (P < 0.001). The mean nausea score in the olanzapine arm was significantly lower than the metoclopramide arm after the initiation of the rescue antiemetic (P = 0.01). Hyperglycemia and drowsiness were more commonly seen in the olanzapine arm. CONCLUSION: Olanzapine is superior to metoclopramide for the treatment of breakthrough CIV in children. Drowsiness and hyperglycemia need to be monitored closely in children receiving olanzapine for breakthrough CIV.

BACKGROUND: Fosaprepitant is a neurokinin-1 receptor antagonist, approved for the prevention of chemotherapy-induced nausea and vomiting. The data on the use of fosaprepitant in children are limited and therefore we conducted a phase III randomized controlled trial. PROCEDURE: Children aged 1-12 years scheduled to receive moderately or highly emetogenic chemotherapy were randomly assigned to arm-A (fosaprepitant) or arm-B (placebo). Children recruited to arm-A received intravenous ondansetron plus dexamethasone followed by fosaprepitant infusion. Children recruited to arm-B received the same drugs as those given to children in arm-A, except that fosaprepitant was substituted with a placebo. Ondansetron and dexamethasone were continued for 48 hours after completion of chemotherapy. The primary end point of the study was to determine the proportion of patients who achieved a complete response (CR), defined as no vomiting, no retching, and no use of rescue medication, during the 24-120 hours (delayed phase) after administration of the last dose of chemotherapy. Secondary end points were the proportion of patients who achieved a CR during the acute phase (0-24 hours) and overall after administration of the last dose of chemotherapy. RESULTS: One-hundred-sixty-three patients were analyzed (81 in the fosaprepitant arm and 82 in the placebo arm). CR rates were significantly higher in the fosaprepitant arm compared to those in the placebo arm during the acute phase (86% vs 60%, P < 0.001), delayed phase (79% vs 51%, P < 0.001), and overall phase (70% vs 41%, P < 0.001). Three (4%) patients in the fosaprepitant arm and sixteen (20%) in the placebo arm required rescue anti-emetics (P = 0.0017). CONCLUSION: Addition of fosaprepitant to ondansetron and dexamethasone improved chemotherapy-induced vomiting control in children treated with moderately or highly emetogenic chemotherapy.

NOTCH1/FBXW7 mutations trigger oncogenic NOTCH1 signaling and its downstream target genes play crucial roles in the molecular pathogenesis of T-cell acute lymphoblastic leukemia (T-ALL). In the present study, NOTCH1 and FBXW7 mutations were studied in 25 primary T-ALL samples. All 34 exons of NOTCH1 and hotspot exons (exon 9 and exon 10) of FBXW7 were polymerase chain reaction amplified and sequenced for mutations. Our results showed that 13/25 (52%) were NOTCH1-mutated, of which 11 patients (44%) showed mutation in the hotspot exons. Four patients (16%) had mutations in non-hotspot exons of NOTCH1. Notably, 2 T-ALL patients (8%) harbored mutations in both hotspot and non-hotspot exons of NOTCH1, whereas 2 patients (8%) had mutations in the hotspot exons of FBXW7. In all, 7 mutations were identified which were not previously reported. The real-time polymerase chain reaction study in 15 patients revealed that increased expression of activated NOTCH1 was found in NOTCH1/FBXW7 hotspot exon-mutated cases. In addition, NOTCH1/FBXW7-mutated patients had showed upregulated HES1, c-MYC, NOTCH3 gene expression. When survival analysis was performed including samples (n=50) from our previous study, an early treatment response and better survival was observed in NOTCH1/FBXW7 hotspot-mutated patients. Our study suggests that NOTCH1/FBXW7 hotspot-mutated T-ALL cases had better response to ALL BFM-95 protocol.

There are no reported cases in the literature of primary renal synovial sarcoma in pediatric patients. The management of renal synovial sarcoma has been extrapolated from the management of soft tissue sarcomas at other sites. We present a 4-year-old female who was suspected to have Wilms' tumor. The patient underwent guided biopsy as she did not respond to neoadjuvant chemotherapy for Wilms' tumor. The biopsy was consistent with primary renal synovial sarcoma. The child was treated with change in her neoadjuvant chemotherapy regimen and surgery. The diagnosis of synovial sarcoma was confirmed by demonstrating the t (X, 18) translocation using polymerase chain reaction.
RESUMO
The NOTCH1 signaling pathway is essential for hematopoiesis and a critical regulatory step for T-cell proliferation and maturation. The E3 ubiquitin ligase FBXW7 controls NOTCH1 protein stability. Mutations in NOTCH1/FBXW7 activate NOTCH signaling and are of prognostic significance in patients with T-cell acute lymphoblastic leukemia (T-ALL). In this study we analyzed NOTCH1 and FBXW7 mutations in 50 South Indian T-ALL patients treated by a modified ALL BFM 95 regimen. The hot spot exons (HD-N, HD-C, TAD, and PEST) of NOTCH1 and exons 9 of the 10 of FBXW7 were polymerase chain reaction amplified and sequenced. In total, 20 of the 50 (40%) T-ALL patients revealed heterozygous mutations in the NOTCH1 domains, and a predominance of missense mutations in HD-N (70%) and PEST (15%) domains. FBXW7 mutations were detected in 5 of the 50 (10%) T-ALL patients. T-ALL patients with NOTCH1/FBXW7 mutations expressed higher protein level of NOTCH1 compared with patients without NOTCH1/FBXW7 mutations. Six of the mutations detected in NOTCH1 were not reported previously. When tested in a Dual Luciferase Renilla reporter assay some of these conferred increased NOTCH activity, suggesting that these are activating mutations. Importantly, 13 of the 20 (65%) NOTCH1/FBXW7-mutated T-ALL patients showed a good prednisone response (P=0.01) and a better clinical outcome compared with NOTCH1/FBXW7 nonmutated patients (P=0.03). These data suggest that NOTCH1/FBXW7 mutations are present in T-ALL patients from Southern India and may be useful biomarkers to predict prognosis in T-ALL.

BACKGROUND/AIMS: Neoadjuvant chemoradiation for rectal cancers may result in complete clinical response (cCR) in some patients. The aim of this study was to analyze the long-term outcomes of such patients in a tertiary cancer center. METHODOLOGY: Patients with rectal cancer who had a cCR to neoadjuvant chemoradiation were divided into two groups: Group A (n=23) did not undergo surgery, and Group B (n=10) underwent elective surgery. The recurrence patterns and survival outcomes were compared between the two groups. RESULTS: After a median follow-up of 72 months (range 12-180), seven patients (30%) in Group A developed an isolated local recurrence. In Group B, after a median follow-up of 37 months (range 12-180) there were no local recurrences. The median disease-free and overall survival was 36 months (range 6-168) and 66 months (range 12-180) in Group A and 36 months (range 12-180) and 37 months (range 18-180) in Group B respectively. CONCLUSIONS: Our results suggest that surgery could be avoided in selected patients with rectal cancer who have a cCR to neoadjuvant chemoradiation. However, until the safety of a non-surgical approach is proven in a prospective randomized trial, it cannot be recommended outside a clinical protocol study.

Background: Carcinoma penis is more common in India compared to the West. The role of chemotherapy in carcinoma penis is ambiguous. We analyzed the profile and outcomes of patients with carcinoma penis treated with chemotherapy. Methods: We analyzed the details of all patients with carcinoma penis treated at our institute between 2012 and 2015. We collected particulars regarding demography, clinical presentation, treatment details, toxicities, and outcomes of these patients. Event-free and overall (OS) survival were calculated from the time of diagnosis until documentation of disease relapse/progression or death for the patients with advanced carcinoma penis who were eligible for chemotherapy. Results: There were 171 patients with carcinoma penis treated at our institute during the study period including 54 (31.6%) patients with stage I, 49 (28.7%) patients with stage II, 24 (14.0%) patients with stage III, 25 (14.6%) patients with stage IV, and 19 (11.1%) patients with recurrent disease at presentation. The present study included 68 patients with advanced carcinoma penis (stages III and IV) who were eligible for chemotherapy, with a median age of 55 years (range: 27-79 years). Sixteen patients received paclitaxel and carboplatin (PC) and 26 patients cisplatin and 5-FluoroUracil (CF). Neoadjuvant chemotherapy (NACT) was given to four patients with stage III and nine patients with stage IV disease. Of the 13 patients given NACT, we observed a partial response in five (38.5%), stable disease in two (15.4%), and progressive disease in five (38.5%) evaluable patients. Six (46%) patients underwent surgery after NACT. Only 28/54 (52%) patients received adjuvant chemotherapy. After a median follow-up of 17.2 months, the 2-year OS rates were 95.8, 89, 62.7, 51.9, and 28.6% for stages I, II, III, IV, and recurrent disease, respectively. The 2-year OS of patients who were given chemotherapy versus those who were not given chemotherapy were 52.7 and 63.2%, respectively (P = 0.762). Conclusions: We report the real-world outcomes of two chemotherapeutic regimens used in consecutive patients with advanced carcinoma penis. Both PC and CF seemed effective and safe. However, approximately half of patients with advanced carcinoma penis do not receive the planned/indicated chemotherapy. We need further prospective trials regarding the sequencing, protocols and indications of chemotherapy in this malignancy.

BACKGROUND: Multiple myeloma (MM) results from clonal expansion of immunoglobulin secreting, heavy chain class-switched, terminally differentiated B-lymphocytes (plasma cells), resulting in radiologic or biochemical evidence of end-organ damage. Though neurological manifestations (peripheral neuropathies, spinal radiculopathies, cranial nerve palsies, and metabolic encephalopathies) can occur during the disease course, direct central nervous system (CNS) infiltration by malignant plasma cells (CNS-MM) is very rare (~1%) and has a dismal prognosis (survival of <6 months). METHODOLOGY: Clinico-laboratory profile and outcome of CNS-MM patients diagnosed and treated at a tertiary cancer care hospital were retrospectively analyzed. RESULTS: On scrutinizing 500 consecutive myeloma case records, 4 patients with CNS-MM were identified. All these patients were diagnosed during myeloma relapse, and all had deceased within 1 week and 12 months of developing CNS infiltration. Our experience with CNS-MM patients is similar to the experiences documented across major world literature. CONCLUSION: Our manuscript reinforces that CNS-MM should be considered in any myeloma patient presenting with unexplainable CNS manifestations. As there are no prospective studies to recommend optimal treatment strategies, CNS-MM still remains a dismal complication of myeloma.

The major challenge in minimal residual disease (MRD) detection is the antigen modulation in post treated samples restraining the use of diagnostic immunophenotypic (IP) signature of leukemic blasts for MRD detection. The IP expression of 10 antigens in 167 children diagnosed as B-acute lymphoblastic leukemia (B-ALL) in comparison to hematogones and the extent of immunomodulation in 60 post treated MRD positive cases were studied. Upregulation was the predictable shift noted in antigens like CD73, CD86, CD19, CD20 and CD45 which was statistically significant for all except CD45. Downregulation was the predictable shift noted in antigens like CD10, CD38, CD58 and CD34 and was statistically significant in all. CD123 showed no significant trend. This immunomodulation in B-ALL results in aberrant expression of antigens during follow-up compared to the diagnostic phenotypic pattern. Hence it is necessary to be aware of the immunomodulations of antigens used in primary diagnosis to avoid being misled during MRD analysis.

Background: T-lymphoblastic leukemia (T-ALL) patients expressing myeloid/stem cell antigens are classified as early T-cell precursor lymphoblastic leukemia (ETP-ALL) or near-ETP-ALL. Methods: Clinico-laboratory profiles, flow cytometric end-of-induction measurable residual disease (EOI-MRD), and survival of treatment naïve T-ALL patients were analyzed according to their immunophenotypic subtypes. Results: Among 81 consecutive T-ALL patients diagnosed, 21% (N=17) were ETP-ALL and 19% (N=15) were near-ETP-ALL. EOI-MRD was detectable in 39% of the 59 samples tested (31.6% of pediatric samples and 52.4% of adult samples). The frequency of EOI-MRD positivity was significantly higher among ETP-ALL (75%, P=0.001) and near-ETP-ALL (71%, P=0.009) patients compared to that in conventional-T-ALL (con-T-ALL) patients (22.5%). CD8 (P=0.046) and CD38 (P=0.046) expressions were significantly upregulated in the EOI blasts of con-T-ALL and ETP-ALL samples, respectively. The 2-year rates of overall (OS), relapse-free (RFS), and event-free survival (EFS) among the T-ALL patients (pediatric vs. adult) was 79.5% vs. 39.8% (P<0.001), 84.3% vs. 60.4% (P=0.026), and 80.3% vs. 38% (P<0.001), respectively. Univariate analysis revealed that 2-year EFS and RFS of pediatric T-ALL patients was independent of T-ALL subtype and was influenced only by EOI-MRD status. However, 2-year OS, RFS, and EFS among adult T-ALL patients were EOI-MRD independent and influenced only by the near-ETP-ALL phenotype. Conclusion: Two-year survival among pediatric and adult T-ALL patients is attributed to EOI-MRD status and near-ETP-ALL phenotype, respectively.
RESUMO
INTRODUCTION: Inflammatory breast carcinoma (IBC) is an aggressive clinical syndrome of invasive breast carcinoma. There is paucity of data regarding the outcomes in IBC. OBJECTIVES: Analyses of OS and Event-free survival (EFS) in nonmetastatic and metastatic IBC and to find prognostic factors influencing them. METHODOLOGY: In this single center, retrospective study the data of patients fulfilling the clinical criteria of IBC were retrieved from 2016 to 2021. The impact of prognostic factors on OS and EFS were analysed by log rank test (univariate analysis). The OS and EFS were depicted as Kaplan Meier survival curves. RESULTS: There were 22 patients with IBC. Median follow-up was 17 months. The median OS was significantly better in non-metastatic(M0) compared to metastatic IBC (25 months vs 6 months) with 3year OS rate of 50% vs 0% respectively. The post-menopausal status, grade 2 histology and trimodality treatment showed better outcome while N3 stage at diagnosis had worse outcome in M0 group. The lesser HR expression, lesser pCR rates, higher N3 proportion, liver metastasis and multiple metastatic site involvement contributed to the worse outcome observed in this study. CONCLUSION: The aggressive clinicopathological features of IBC in the present study resulted in less favourable outcome compared to literature review. Improved outcome with trimodality highlights the emergent need for additional targeted therapy to improve pCR and operability.

INTRODUCTION: Flow cytometric immunophenotyping (FCI) plays a major role in diagnosing hematologic malignancies. In patients diagnosed with precursor B-lineage acute lymphoblastic leukemia (B-ALL), expression of certain non-lineage/cross lineage antigens is of prognostic and cytogenetic relevance. There is a paucity of studies that have comprehensively analyzed the clinical and laboratory profiles of B-ALL patients showing aberrant T/natural killer (NK) cell antigen expression. MATERIALS AND METHODS: This is a prospective study where 152 consecutive B-ALL patients were analyzed for aberrant expression of T/NK cell antigens (CD1a, CD5, CD4, CD7, CD8 and CD56) by FCI. The clinical and laboratory profile of these T/NK-cell antigen-expressing B-ALL patients was statistically analyzed against conventional B-ALL patients. RESULTS: In our B-ALL cohort, CD5, CD7 and CD56 expression were observed in one, six and nine patients, respectively. CD56-expressing B-ALL patients were predominantly children (89%) and presented as standard clinical risk (p=0.010) disease with frequent ETV6-RUNX1 fusion (p=0.021) positivity. On the contrary, CD7-expressing B-ALL patients were adolescent-young adult/adult-age skewed (83%) and had an adverse cytogenetic profile (p=0.001), especially for the frequent presence of BCR-ABL1 fusion (p=0.004) and KMT2A rearrangement (p=0.045). CD7-expressing B-ALL patients had inferior event-free survival (p=0.040) than their CD56-expressing counterparts, but there was no significant difference in the overall survival (p=0.317). CONCLUSION: In comparison to conventional B-ALL patients, there are significant differences in the age, cytogenetic profile and event-free survival of T/NK-cell antigen-expressing B-ALL patients.
RESUMO
The nomenclature high-grade non-Hodgkin's lymphoma was repurposed in the World Health Organization (WHO) 2016 update as high-grade B cell lymphoma (HGBL). However, among the HGBL entities HGBL, not otherwise specified (NOS) remains a poorly described entity with a lack of literature regarding its treatment and prognosis. The baseline characteristics, treatment, and outcome of HGBL, NOS cases were analyzed. Thirty HGBL, NOS patients were diagnosed between January 2017 and December 2019. Their median age was 49.3 years, and 30% had advanced IPI. The majority received R-CHOP chemotherapy, while five patients received dose-adjusted R-EPOCH. At a median follow-up of 15 months, nine patients had disease progression or relapse. EFS and OS were 22 months (12.1-31.9 months) and 37 months (29.4-44.0 months) respectively. Only NCCN-IPI ≤ 2 showed significant influence on the outcome. The results were similar to the outcomes previously reported. This study highlights the importance of NCCN-IPI in ascertaining the prognosis of HGBL, NOS. The literature review suggests that more intensive chemotherapy is ideal for HGBL, NOS. However, prospective trials are needed to prove whether the treatment of HGBL, NOS can be tailored based on NCCN-IPI.
RESUMO
The optimal management in Oligometastatic (OM) breast carcinoma is not defined. OBJECTIVES: To identify the prognostic factors influencing OM and the effect of Locoregional treatment (LRT) on survival in OM. METHODOLOGY: Patients with ≤5 metastases and each with ≤ 5 cm size were defined as OM. Data of OM were extracted from the Institute Registry between 2012 and 2018. The impact of prognostic factors on survival was analysed by univariate and multivariate Cox regression. The Kaplan Meier survival curves were used to plot PFS and OS. RESULTS: There were 170 patients with OM. The median follow-up was 61 months. Median OS was 43.3 months. The median OS was 74 months in OMD vs 22.7 months in Oligorecurrent disease (ORD) with 5year OS rate of 55.3% vs 16.5% respectively. In the multivariate analyses of OMD both Ki67 ≤ 50% and hormone therapy (HT) showed significant favourable survival outcome. While premenopausal status and HT showed significant survival benefits in ORD. The worse survival outcome in ORD could be because of their aggressive biology and deficit in LRT compared to literature review. The prognostic factors were swayed by the uneven distribution of HR status, grade and Ki67. CONCLUSION: The survival of OM was influenced by OMD, Ki67 ≤ 50%, premenopausal status and HT. The lesser survival rates of OM in the long term suggest the need for curative LRT to metastatic sites and primary tumor. The potential role of HT and targeted therapy with or without LRT need to be assessed in future randomised trials.

There is limited data on the impact of treatment interruptions due to nonadherence in patients with chronic phase chronic myeloid leukemia (CP-CML) treated with Imatinib. We looked at factors (including adherence to therapy) affecting the outcome in a large cohort of patients with CP-CML. All the 516 patients received Imatinib free-of-cost through a company sponsored scheme, which mandated regular three monthly visits for drug procurement. Data regarding the disease characteristics, adherence to treatment and outcomes, were obtained from patients records. Unwarranted interruption of treatment for more than 1 week was defined as nonadherence. With a median follow-up of 39 months, the estimated 5-year event free survival (EFS) was 70.8% (95%, CI = 63.3-78.3). Nearly one-third of the patients (29.6%) were found to be nonadherent at some point during their treatment. On univariate analysis, the factors adversely affecting the EFS were prolonged symptom duration before diagnosis, treatment with hydroxyurea for more than 1 month before start of Imatinib, and nonadherence to therapy. Only nonadherence was significant in multivariate analysis (HR1.6; P = 0.048). The 5-year EFS in adherent and nonadherent patients was 76.7% and 59.8% respectively (P = 0.011, log rank test). Nonadherent patients were less likely to achieve complete cytogenetic responses (26% versus 44%; P = 0.004; χ(2) test) at any point. A significant proportion of patients with CP-CML have drug interruptions due to nonadherence during therapy and this compromises the EFS. Adherence to therapy must be included as an important evaluation parameter in all future studies of CML.

OBJECTIVE: To evaluate the efficacy and toxicity of etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO) chemotherapy for the treatment of high-risk gestational trophoblastic neoplasia (GTN). STUDY DESIGN: Thirty-five patients with high-risk GTN were treated with 196 cycles of EMA-CO between 1997 and 2006. Twenty-nine patients received EMA-CO in the primary setting and another 6 after failure of single-agent chemotherapy. Salvage chemotherapy was offered to selected patients. RESULTS: Of the 29 patients treated with EMA-CO in the primary setting, 22 (75.8%) had a complete clinical response, 5 (17.1%) progressed, and 2 (7.1%) had early deaths. Three patients relapsed after achieving initial complete response. Five were treated with salvage chemotherapy, of which only 2 survived. This translated to overall survival rate of 71% in the primary setting. Five of the 6 patients treated with EMA-CO as second line are survivors. Life threatening toxicity was not seen after EMA-CO. Nine subsequent normal pregnancies were reported after EMA-CO. CONCLUSION: EMA-CO was highly effective for the management of high-risk GTN, and the toxicities were minimal. Reproductive outcome after treatment with EMA-CO was excellent.

Intravesical BCG therapy is an integral part of management of non-muscle invasive bladder cancers. Our aim is to analyze the non-muscle invasive bladder cancer patients treated at our center with a modified schedule intravesical BCG therapy. Data from patients treated at our center from 2009 to 2017 was collected from patient records and analyzed. A 6-weekly 120-mg induction course followed by 6 monthly 120 mg has been used at our institute for NMIBC. Clinicopathological and treatment variables were collected. A total of 119 patients were treated at our center with a median follow-up period of 4.18 years with the above schedule. Nearly 96% patients were able to complete induction therapy and 79% completed the maintenance therapy. The 5-year recurrence-free survival was 83%. The recurrence and progression rates were 16.8% and 4.2% respectively. About 60% of the patients suffered from side effects of BCG with 11% having class 3 or 4 toxicity. Our regimen of monthly maintenance intravesical BCG for 6 months shows good control rates with high compliance, similar to those of other contemporary series, although with higher incidence of high-grade toxicity.
