Abstract
High-sensitivity multicolour flow cytometry (MFC)-based B-lymphoblastic leukaemia (B-ALL) measurable residual disease (BMRD) assay is increasingly being used in clinical practice. Herein, we describe six consistently present low-level populations immunophenotypically mimicking abnormal B-ALL blasts in 441 BMRD samples from 301 children. These included CD19+ CD123+ plasmacytoid dendritic cells differentiating from lymphoid precursors, CD10+ transitional B cells with CD10+ /CD38dim-to-negative/CD20bright/CD45bright phenotype, CD19+ natural killer (NK) cells, CD73bright/CD10+ mesenchymal stromal/stem cells, CD73bright/CD34+ endothelial cells, and a CD34+ CD38dim-to-negative/CD10- /CD20bright/CD45bright subset of mature B cells. We provide the proportions, comprehensive immunophenotype, and practical clues for proper identification of these low-level populations. Knowledge regarding the presence and immunophenotype of these mimics is essential for accurate interpretation in high-sensitivity MFC-BMRD analysis.

Abstract
BACKGROUND The adverse influence of undernutrition in children with cancer may be remediated by early nutritional intervention. This study assessed the efficacy of ready-to-use therapeutic food (RUTF) in improving nutritional status and reducing treatment-related toxicities (TRTs) in such children. METHODS In a randomized controlled phase-3 open-label trial, severely and moderately undernourished children with cancer were randomized 1:1 to receive standard nutritional therapy (SNT) or SNT+RUTF for 6 weeks. The primary outcome (weight gain >10%) and secondary outcomes (improved/maintained nutritional status, improved body composition) were assessed after 6 weeks. TRTs were assessed over 6 months. RESULTS Between July 2015 and March 2018, 260 subjects were enrolled, 126 were analyzable in both arms at 6 weeks. More children on RUTF had weight gain (98 [77.8%] vs. 81 [64.2%], p = .025) with a greater increase in fat mass as a percentage of body mass (median 2% [IQR -0.12 to 4.9] vs. 0.5% [IQR -1.45 to 2.27, p = .005]) but a greater loss of lean mass (median -1.86% [IQR -4.4 to 0.50] vs. -0.4% [IQR -2.4 to 1.4, p = .007]) compared to the SNT arm. Fewer subjects on the RUTF arm had episodes of severe infection (10.6% vs. 31%, p < .0001), treatment delays (17.7% vs. 39%, p < .0001), and severe mucositis (11% vs. 23.8%, p = .006) compared to the SNT arm. The odds of developing TRTs on the RUTF arm were lower even after adjusting for improvement in nutritional status. CONCLUSIONS RUTF is efficacious in improving weight gain and nutritional status in undernourished children with cancer and decreases TRTs. Incorporating RUTF into a healthy, balanced diet should be considered in undernourished children with cancer.

Abstract
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.

Abstract
Acute Myeloid Leukemia (AML) is a heterogeneous disease with respect to morphology, immunophenotype, chromosomal abnormalities and genetic lesions. While a majority of AML cases harbour recurrent chromosomal abnormalities, several rare, apparently unique or novel aberrations may be identified by conventional cytogenetics. In fact, with the prognostic relevance of chromosomal abnormalities, and with the advent of new-age, target-specific therapy, identifying such aberrations becomes vital. In this study, we present a case of pediatric AML with ins(19;X)(q13.1;p11.2q28) and t(1;11)(q10;p10), both, novel, previously unreported chromosomal abnormalities in AML. Post induction, both these clonal cytogenetic abnormalities persisted. The documentation of this case will help determine the significance of these cytogenetic abnormalities. Also, this case exemplifies the importance of cytogenetics in the complete characterization and risk stratification of AML patients.

Abstract
Background Recently, anti-CD38 monoclonal antibody (Mab) therapy has become a focus of attention as an additional/alternative option for many hematological neoplasms including T-cell acute lymphoblastic leukemia (T-ALL). It has been shown that antitumor efficacy of anti-CD38-Mab depends on the level of CD38 expression on tumor cells. Reports on CD38 expression in T-ALL are scarce, and data on the effect of cytotoxic chemotherapy on CD38 expression are limited to very few samples. Moreover, it lacks entirely in refractory disease and in adult T-ALL. We report the flow cytometric evaluation of CD38 expression in T-ALL blasts at diagnosis and the effect of cytotoxic chemotherapy on its expression in measurable residual disease (MRD), refractory disease (MRD≥5%), and relapsed disease in a large cohort of T-ALL. Methods The study included 347 samples (188 diagnostic, 100 MRD, 24 refractory and 35 relapse samples) from 196 (children: 85; adolescents/adults: 111) patients with T-ALL. CD38-positive blasts percentages (CD38-PBPs) and expression-intensity (mean fluorescent intensity, CD38-MFI) were studied using multicolor flow cytometry (MFC). MFC-based MRD was performed at the end-of-induction (EOI-MRD, day 30–35) and end-of-consolidation (EOC-MRD, day 78–85) subsequent follow-up (SFU-MRD) points. Results Patients were classified into early thymic precursor subtype of T-ALL (ETPALL, 54/188, 28.7%), and non-ETPALL (134/188, 71.3%). Of 188, EOI-MRD assessment was available in 152, EOC-MRD was available in 96 and SFU-MRD was available in 14 patients. CD38 was found positive in 97.9% (184/188) of diagnostic, 88.7% (110/124) MRD (including 24-refractory) and 82.9% (29/35) relapsed samples. Median (95% CI) of CD38-PBPs/MFI in diagnostic, MRD, refractory, and relapsed T-ALL samples were, respectively, 85.9% (82.10%–89.91%)/4.2 (3.88–4.47), 74.0% (58.87%–83.88%)/4.6 (3.67–6.81), 79.6% (65.25%–96.11%)/4.6 (3.33–8.47) and 85.2% (74.48%–93.01%)/5.6 (4.14–8.99). No significant difference was noted in CD38 expression between pediatric versus adult and patients with ETPALL versus non-ETPALL. No change was observed in CD38-MFI between diagnostic versus MRD and diagnostic versus relapsed paired samples. However, we noticed a mild drop in the CD38-PBPs in MRD samples compared with the diagnostic samples (p=0.016). Conclusion We report an in-depth analysis of CD38 expression in a large cohort of T-ALL at diagnosis, during chemotherapy, and at relapse. Our data demonstrated that CD38 is robustly expressed in T-ALL blasts with a little effect of cytotoxic chemotherapy making it a potentially effective target for antiCD38-Mab therapy.

Abstract
Abstract
Background Bloodstream infections with drug-resistant bacteria are associated with a higher morbidity and mortality. Based on previous studies in our institution demonstrating a rising incidence of multidrug resistant organism (MDR) bacteria in bloodstream infections (BSI) and high prevalence of enteric colonization with MDR, the “de-escalation” strategy for empirical antibiotics was adopted in the management of febrile neutropenia in children with hematolymphoid malignancies and MDR colonization. An audit was carried out to determine whether surveillance rectal swabs correlated with blood cultures in febrile neutropenia.
Methods Patient data from January 2015 to July 2016 was examined. Rectal swabs of children with hematolymphoid malignancies were obtained at presentation. Blood cultures were taken during febrile neutropenia. Data were analyzed using SPSS version 24.0. The significance level was set at p < 0.05.
Results Most patients (62.1%) with confirmed BSI were colonized with either extended-spectrum β-lactamase producing organisms (ESBLO) (31.9%) or MDR (30.2%). Majority 116 (62.7%) developed BSI caused by either MDR or ESBLO. In contrast, only 12 (10.6%) patients colonized by sensitive bacteria, developed BSI caused by either MDR or ESBLO. These differences were statistically significant (p < 0.001). Thus, the baseline rectal swab had a sensitivity and a specificity of 90.6% and 59.4%, respectively, in predicting BSI with either MDR or ESBLO.
Conclusions We conclude that high prevalence of MDR colonization at presentation significantly results in MDR BSI, which further results in a significant increase in intensive care unit admissions and mortality. This would justify the use of a “de-escalation” antibiotic policy. Whether such a strategy has been successful in impacting outcomes, would need further study.

Abstract
Abstract
Background: In-spite of the standard neoadjuvant and adjuvant therapies, stage for stage many more patients with TNBC relapse. This may be because of lack of effective maintenance therapy for TNBC Pts. Recently MMT is being explored to improve outcomes in TNBC. We present a retrospective and prospective analysis of consecutive Pts with TNBC treated at BKLWalawalkarHospital, the rural outreach center of Tata Memorial Centre (India), wherein the outcome of TNBC Pts receiving MMT is being compared to historical control group who did not receive the same.
Methods: After standard anthracycline or anthracycline+taxane based therapy, TNBC Pts were either observed (Sept 2003 to March 2011) or received MMT (Nov 2008 to Dec 2018).MMT consisted of 2 phases: initial 12 weeks of daily oral celecoxib (200 mg BD) and cyclophosphamide (50 mg OD) along with 12 doses of weekly IV cisplatin (25 mg/m2). This was followed by 1 year of Phase II maintenance consisting of oral daily metformin (500 mg BD), cyclophosphamide (50 mg OD) along with weekly methotrexate (12 mg/m2).When CAF is the standard regimen 2 phases of maintenance was given , after anthracyclines and taxanes were proved as a standard regimen maintenance was restricted to Phase II considering overlapping toxicities like neuropathy.
Results: There were 118 evaluable TNBC Pts. 25 Pts did not receive any MMT.Of the 93 remaining Pts initial 25 received both Phase I & II MMT , 1 patient received only phase I and subsequent 61 Pts have received only Phase II MMT. 6 patients progressed while on initial standard therapy and were not evaluable to assess the effect of MMT .Hence 112 patients are analysed further for outcome.STAGE STRATIFICATION : 8 Pts(6.7%) had AJCC Stage I; 48 Pts(40.6%) had AJCC Stage II; & 62 patients(52.5) had AJCC Stage III disease.MMT and observation groups were comparable with respect to baseline characteristics such as age & stage . Out of 112 patients 87 received MMT and 9 events were noted ,25 did not received MMT and 12 events were noted.EFS by March 2020 is 89.7% in MMT group and 52% in non- MMT group . Median EFS in MMT group is 11.3 yrs ( 9.4 yrs-13.14 yrs 95% CI) , in Off MMT group median EFS 9.2 yrs( 6.4-12 yrs 95% CI).Overall comparison was done by Log rank analysis (Significance 0.006).Median overall survival in OMCT group is 11.8yrs ( 9.9yrs-13.8yrs 95% CI), in non MMT group OS is 9.8yrs( 7.1 yrs-12.6yrs) with significance 0.002.61 patients who received Phase II MMT OS is 13.4 yrs ( 12.5yrs-14.4 yrs 95% CI).By stage stratification in non MMT group 2 patients belong to Stage I , 9patients belongs to Stage II and 14 patients belongs to Stage III.
TOXICITIES : MTX 25% dose reduction was done in 7 patients due to Grd2 Mucositis, cyclophosphamide alone was stopped in 1 patient due to grade 3 fatigue, MTX and Cyclophosphamide was stopped in 2 patientsdue grade3 anemia and grade 4 neutropenia, blood transfusion was done in them.Toxicities are much less when compared to CREATEX trial and the follow up duration is very long.
Conclusion: Most of the TNBC patients relapse in the early period of follow up and there is an unmet need in the improvement of management. If low dose chemotherapy is given for 1 yr there is a significant improvement in EFS and OS without muchdecrease in QOL.l. This strategy is worthy of being evaluated in definitive randomized trials in TNBC women with large numbers.

Abstract
Background: We are a tertiary care cancer center and have approximately 1000–1500 emergency visits by cancer patients undergoing treatment under the adult medical oncology unit each month. However, due to the lack of a systematic audit, we are unable to plan steps toward the improvement in quality of emergency services, and hence the audit was planned. Methods: All emergency visits under the adult medical oncology department in the month of July 2015 were audited. The cause of visit, the demographic details, cancer details, and chemotherapy status were obtained from the electronic medical records. The emergency visits were classified as avoidable or unavoidable. Descriptive statistics were performed. Reasons for avoidable emergency visits were sought. Results: Out of 1199 visits, 1168 visits were classifiable. Six hundred and ninety-six visits were classified as unavoidable (59.6%, 95% CI: 56.7–62.4), 386 visits were classified as probably avoidable visit (33.0%, 95% CI: 30.4–35.8) whereas the remaining 86 (7.4%, 95% CI: 6.0–9.01) were classified as absolutely avoidable. Two hundred and ninety-seven visits happened on weekends (25.6%) and 138 visits converted into an inpatient admission (11.9%). The factors associated with avoidable visits were curative intention of treatment (odds ratio - 2.49), discontinued chemotherapy status (risk ratio [RR] - 8.28), and private category file status (RR – 1.89). Conclusion: A proportion of visits to emergency services can be curtailed. Approximately one-fourth of patients are seen on weekends, and only about one-tenth of patients get admitted.

Abstract
Aim Data regarding the optimal management of metastatic anorectal melanoma (mARM) is scarce. The primary aim was to evaluate the potential benefits of systemic therapy in mARM. Materials and Methods This is a retrospective analysis of all mARM who presented between July 2013 and June 2015 at the Department of GI Medical Oncology, Tata Memorial Hospital. Results Of a total of 37 patients, twelve patients were planned for best supportive care (BSC) only while the remaining 25 patients received systemic therapy. The median overall survival (OS) for the whole cohort was 27 weeks. The OS was significantly better in patients who received first-line therapy as compared to those who were offered BSC (median OS: 14 vs. 33 weeks; P = 0.04). Patients with PS of 1 did significantly better than PS of 2 more (OS 70 vs. 17 weeks; P = 0.015). Conclusion mARM should be offered chemotherapy, especially in good performance patients. Paclitaxel/Platinum or Capecitabine/Temozolomide regimens can be considered as the preferred regime in the resource-limited setting where immunotherapy may not be a feasible option.

Abstract
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 < .001], uncontrolled cancer status vs controlled cancer (30-day mortality37.5%% vs 4%%, OR 14, 95% CI 4.46-44.16, P < .001) and severe COVID-19 vs mild COVID-19 (30-day mortality 71% vs 3%, OR 92.29, 95% CI 26.43-322.21, P < .001) were significantly associated with mortality. The median time to SARS-CoV-2 RT-PCR negativity was 17 days [interquartile range (IQR)17-28) in the cohort. CONCLUSIONS The mortality rates in cancer patients with COVID-19 who are receiving systemic anti-cancer therapy in LMICSs are marginally higher than that reported in unselected COVID-19 cohorts with prolonged time to viral negativity in a substantial number of patients. The pediatric cancer patients tended to have favorable outcomes.

Outcomes with nondose-dense chemotherapy for Ewing sarcoma: A practical approach for the developing world. Pediatr Blood Cancer 2020; 67:e28604. [PMID: 32706522 DOI: 10.1002/pbc.28604] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Revised: 06/17/2020] [Accepted: 07/05/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND 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. PROCEDURE 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. RESULTS 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 control >4 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. CONCLUSIONS 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.

Increased toxicities in children with Burkitt lymphoma treated with rituximab: Experience from a tertiary cancer center in India. Pediatr Blood Cancer 2020; 67:e28682. [PMID: 32865865 DOI: 10.1002/pbc.28682] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 08/16/2020] [Accepted: 08/18/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND Even though rituximab has emerged as standard of care for the management of high-risk pediatric Burkitt lymphoma (BL), its safety in children from the low-middle-income countries (LMICs) remains to be proven. We herein report our experience of using rituximab in children with BL. METHODS All patients diagnosed with BL between January 2015 and December 2017 were treated in a risk-stratified manner with either the modified MCP-842 or modified LMB protocol. Patients with poor response to MCP-842 were switched to the LMB-salvage regimen. In addition, rituximab was given to selected high-risk patients. RESULT Forty-two (49.4%) of 85 patients with BL received rituximab. The incidence of febrile neutropenia (90.5% vs 67.4%; P = 0.02), pneumonia (38.1% vs 11.6%; P = 0.005), intensive care unit admissions (54.5% vs 17.6%; P = 0.002), and toxic deaths (26.2% vs 9.3%; P = 0.04) was higher among BL patients who received rituximab. Pneumonia was fatal in 11 of 16 (69%) patients who received rituximab. On multivariate analysis, rituximab continued to be significantly associated with toxic deaths ( OR: 11.45 [95% CI: 1.87-70.07; P = 0.008]). The addition of rituximab to intensive chemotherapy resulted in an inferior one-year event-free survival (49.4% ± 8.1% vs 79.3% ± 6.5%; P = 0.025) and one-year overall survival (63.1% ± 8.5% vs 91.8% ± 4.5%; P = 0.007) with no improvement in one-year relapse-free survival (78.3% ± 7.3% vs 83.9% ± 6.0%; P = 0.817). CONCLUSION Rituximab was associated with increased toxicities and toxic deaths in our patients. The potential immunomodulatory effect of rituximab and increased susceptibility to infections in patients from LMICs have to be carefully considered while choosing this drug in the treatment of BL in resource-constrained settings.

Sudden blast phase in pediatric chronic myeloid leukemia-chronic phase with abnormal lymphoid blasts detected by flow cytometry at diagnosis: Can it be considered a warning sign? CYTOMETRY PART B-CLINICAL CYTOMETRY 2020; 100:345-351.

Abstract
BACKGROUND Inconclusive knowledge persists regarding the course of chronic myeloid leukemia-chronic phase (CML-CP) patients with detectable abnormal blasts by flow-cytometry at diagnosis. The 2016 WHO classification is not specific regarding sub-classification of CML with <10% abnormal B-lymphoid blasts (ABLB), and suggests these patients often show rapid progression. We report the clinical course of pediatric CML-CP patients who had detectable abnormal blasts by flow-cytometry at baseline. METHODS Retrospective audit of all pediatric CML patients between January 2013 and December 2017 were included. Their clinical presentation, demographic profile, and treatment outcomes were extracted from electronic medical records. Some of these patients got flow-cytometry done by default, though it was not a routine part of diagnostic CML marrow studies. RESULTS Amongst 65 pediatric CML patients, flow-cytometry at initial diagnosis was available in 15 (CP-12; AP-3). Of the 12 CML-CP patients, 10 (83%) had abnormal flow-cytometric findings-5 (50%) with mixed lineage blasts (4-B/Myeloid, 1-B/T/Myeloid), and myeloid lineage blasts in the remaining 5 (50%). At a median follow-up of 26 months (range: 9-34 months), 3/5 patients with ABLB at diagnosis progressed to frank blast crisis (2 B-cell; 1 Mixed lineage). None among the five patients with diagnostic myeloid-alone aberrant blasts progressed to blast crisis. Imatinib resistant mutation was also found in 3/5 (60%) CML-CP patients with these ABLB at baseline. CONCLUSIONS Although a retrospective study with limited sample size, presence of ABLB detected on flow-cytometry in CML-CP patients, had a noticeable early conversion to CML-BC in our cohort. Incorporation of flow-cytometry in diagnostic work-up can provide useful insight regarding the behavior of pediatric CML-CP patients and guide therapy.

Abstract
Accurate knowledge of expression patterns/levels of commonly used MRD markers in regenerative normal-B-cell-precursors (BCP) is highly desirable to distinguish leukemic-blasts from regenerative-BCP for multicolor flow cytometry (MFC)-based measurable residual disease (MRD) assessment in B-lymphoblastic leukemia (B-ALL). However, the data highlighting therapy-related immunophenotypic-shift in regenerative-BCPs is scarce and limited to small cohort. Herein, we report the in-depth evaluation of immunophenotypic shift in regenerative-BCPs from a large cohort of BALL-MRD samples. Ten-color MFC-MRD analysis was performed in pediatric-BALL at the end-of-induction (EOI), end-of-consolidation (EOC), and subsequent-follow-up (SFU) time-points. We studied normalized-mean fluorescent intensity (nMFI) and coefficient-of-variation of immunofluorescence (CVIF) of CD10, CD19, CD20, CD34, CD38, and CD45 expression in regenerative-BCP (early, BCP1 and late, BCP2) from 200 BALL-MRD samples, and compared them with BCP from 15 regenerating control (RC) TALL-MRD samples and 20 treatment-naïve bone-marrow control (TNSC) samples. Regenerative-BCP1 showed downregulation in CD10 and CD34 expression with increased CVIF and reduced nMFI (p < 0.001), upregulation of CD20 with increased nMFI (p = 0.014) and heterogeneous CD45 expression with increased CVIF (p < 0.001). Immunophenotypic shift was less pronounced in the BCP2 compared to BCP1 compartment with increased CVIF in all but CD45 (p < 0.05) and reduced nMFI only in CD45 expression (p = 0.005). Downregulation of CD10/CD34 and upregulation of CD20 was higher at EOI than EOC and SFU time-points (p < 0.001). Regenerative-BCPs are characterized by the significant immunophenotypic shift in commonly used B-ALL-MRD markers, especially CD10 and CD34 expression, as compared to treatment-naïve BCPs. Therefore, the templates/database for BMRD analysis must be developed using regenerative-BCP.

Low-cost oral metronomic chemotherapy versus intravenous cisplatin in patients with recurrent, metastatic, inoperable head and neck carcinoma: an open-label, parallel-group, non-inferiority, randomised, phase 3 trial. LANCET GLOBAL HEALTH 2020; 8:e1213-e1222. [PMID: 32827483 DOI: 10.1016/s2214-109x(20)30275-8] [Citation(s) in RCA: 50] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 05/20/2020] [Accepted: 05/27/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Regimens for palliation in patients with head and neck cancer recommended by the US National Comprehensive Cancer Network (NCCN) have low applicability (less than 1-3%) in low-income and middle-income countries (LMICs) because of their cost. In a previous phase 2 study, patients with head and neck cancer who received metronomic chemotherapy had better outcomes when compared with those who received intravenous cisplatin, which is commonly used as the standard of care in LMICs. We aimed to do a phase 3 study to substantiate these findings. METHODS We did an open-label, parallel-group, non-inferiority, randomised, phase 3 trial at the Department of Medical Oncology, Tata Memorial Center, Homi Bhabha National Institute, Mumbai, India. We enrolled adult patients (aged 18-70 years) who planned to receive palliative systemic treatment for relapsed, recurrent, or newly diagnosed squamous cell carcinoma of the head and neck, and who had an Eastern Cooperative Oncology Group performance status score of 0-1 and measurable disease, as defined by the Response Evaluation Criteria In Solid Tumors. We randomly assigned (1:1) participants to receive either oral metronomic chemotherapy, consisting of 15 mg/m2 methotrexate once per week plus 200 mg celecoxib twice per day until disease progression or until the development of intolerable side-effects, or 75 mg/m2 intravenous cisplatin once every 3 weeks for six cycles. Randomisation was done by use of a computer-generated randomisation sequence, with a block size of four, and patients were stratified by primary tumour site and previous cancer-directed treatment. The primary endpoint was median overall survival. Assuming that 6-month overall survival in the intravenous cisplatin group would be 40%, a non-inferiority margin of 13% was defined. Both intention-to-treat and per-protocol analyses were done. All patients who completed at least one cycle of the assigned treatment were included in the safety analysis. This trial is registered with the Clinical Trials Registry-India, CTRI/2015/11/006388, and is completed. FINDINGS Between May 16, 2016, and Jan 17, 2020, 422 patients were randomly assigned: 213 to the oral metronomic chemotherapy group and 209 to the intravenous cisplatin group. All 422 patients were included in the intention-to-treat analysis, and 418 patients (211 in the oral metronomic chemotherapy group and 207 in the intravenous cisplatin group) were included in the per-protocol analysis. At a median follow-up of 15·73 months, median overall survival in the intention-to-treat analysis population was 7·5 months (IQR 4·6-12·6) in the oral metronomic chemotherapy group compared with 6·1 months (3·2-9·6) in the intravenous cisplatin group (unadjusted HR for death 0·773 [95% CI 0·615-0·97, p=0·026]). In the per-protocol analysis population, median overall survival was 7·5 months (4·7-12·8) in the oral metronomic chemotherapy group and 6·1 months (3·4-9·6) in the intravenous cisplatin group (unadjusted HR for death 0·775 [95% CI 0·616-0·974, p=0·029]). Grade 3 or higher adverse events were observed in 37 (19%) of 196 patients in the oral metronomic chemotherapy group versus 61 (30%) of 202 patients in the intravenous cisplatin group (p=0·01). INTERPRETATION Oral metronomic chemotherapy is non-inferior to intravenous cisplatin with respect to overall survival in head and neck cancer in the palliative setting, and is associated with fewer adverse events. It therefore represents a new alternative standard of care if current NCCN-approved options for palliative therapy are not feasible. FUNDING Tata Memorial Center Research Administration Council.
