RESUMO

The real-world data on short course of immune checkpoint inhibitor (ICI) use are sparse and merit exploration. A multicentric observational study on the safety and efficacy of ICI in oncology patients between August 2014 and October 2020 involves 1011 patients across 13 centers in India. The median age was 59 (min 16-max 98) years with male preponderance (77.9%). The predominant cohort received short-course ICI therapy; the median number of cycles was 5 (95% confidence interval [CI] 1-27), and the median duration of therapy was 3 (95% CI 0.5-13) months. ICIs were used commonly in the second and third line setting in our study (66.4%, n = 671). Objective response rate (complete or partial response) was documented in 254 (25.1%) of the patients, 202 (20.0%) had stable disease, and 374 (37.0%) had progressive disease. The clinical benefit rate was present in 456 (45.1%). Among the patients whom ICI was stopped (n = 906), the most common reason for cessation of ICI was disease progression (616, 68.0%) followed by logistic reasons like financial constraints (234, 25.82%). With a median follow-up of 14.1 (95% CI 12.9-15.3) months, there were 616 events of progression and 443 events of death, and the median progression free survival and overall survival were 6.4 (95% CI 5.5-7.3) and 13.6 (95% CI 11.6-15.7) months, respectively, in the overall cohort. Among the immune-related adverse events, autoimmune pneumonitis (29, 3.8%) and thyroiditis (24, 2.4%) were common. Real-world multicentric Indian data predominantly with short-course ICI therapy have comparable efficacy/safety to international literature with standard ICI therapy.

RESUMO

AIM: The outcome of radical surgery in nonmetastatic anorectal melanoma (AM) patients is studied infrequently. Here, we aimed to explore the stage-wise outcomes and the impact of radical resections in these patients. METHODS: In this single-centre retrospective study, data of 154 eligible patients were recorded and analysed. Data were obtained from November 2010 to September 2019 with follow-up until November 2020. Overall survival (OS) and disease-free survival (DFS) was calculated by Kaplan Meir method and univariate analysis of prognostic factors by Cox regression. RESULTS: Of 154 patients, 110 were metastatic (stage III) and 44 were nonmetastatic (stage I:22, stage II:22) and underwent curative resections. Median follow-up was 48 months (14-119 months). A total of 39 patients underwent total mesorectal excisions (TME) and five transanal excision (TAE) were performed. Seven patients underwent extended resections. Stage I and II patients had 3- and 5-year OS of 40% and 36%; and DFS of 45% and 33.2%, respectively. Median OS and DFS were 31 and 24 months, respectively. Stage II (node-positive) patients had better median OS compared to stage III (21 vs. 4 months; p = 0.000), and 54.5% patients had recurrences, most commonly both systemic and nodal (45.83%). Median OS of patients without recurrence was 34 months. CONCLUSION: In this large surgical series of AMs, outcome in stage I and II patients was significantly better than stage III and patients with stage II disease can have acceptable oncological outcomes. Radical surgical resections with or without lymphadenectomy could be considered in these patients. The role of adjuvant systemic therapy and radiation needs to be explored as part of multimodality treatment.

RESUMO

BACKGROUND: Young (≤40 years) breast cancers (YBC) are uncommon, inadequately represented in trials and have unique concerns and merit studying. METHODS: The YBC treated with a curative intent between 2015 and 2016 at our institute were analysed. RESULTS: There were 1228 patients with a median age of 36 (12-40) years; 38 (3.1%) had Stage I, 455 (37.1%) - II, 692 (56.3%) -III, and remaining 43 (3.5%) Stage IV (oligo-metastatic) disease; 927 (75.5%) were node positive; 422 (34.4%) were Triple negatives (TNBC), 331 (27%) were HER-2 positive. There were 549 (48.2%) breast conservations and 591 (51.8%) mastectomies of which 62 (10.4%) underwent breast reconstruction. 1143 women received chemotherapy, 617 (53.9%) received as neoadjuvant and 142 (23.1%) had pathological complete response; 934 (81.9%) received adjuvant radiotherapy. At the median follow-up of 48 (0-131) months, 5-year overall and disease-free survival was 79.6% (76.8-82.5) and 59.1% (55.8-62.6). For stage I, II, III and IV, the 5-year overall-survival was 100%, 86.7% (82.8-90.6), 77.3% (73.4-81.2), 69.7% (52.5-86.9) and disease-free survival was 94% (85.9-100), 65.9% (60.3-71.5), 55% (50.5-59.5), and 29.6% (14-45.2) respectively. On multivariate analysis, TNBC and HER-2+ subgroups had poorer survival (p = 0.0035). 25 patients had BRCA mutations with a 5-year DFS of 65.1% (95% CI:43.6-86.6). Fertility preservation was administered in 104 (8.5%) patients; seven women conceived and 5 had live births. Significant postmenopausal symptoms were present in 153 (13%) patients. CONCLUSION: More than half of the YBC in India were diagnosed at an advanced stage with aggressive features leading to suboptimal outcomes. Awareness via national registry and early diagnosis is highly warranted. Menopausal symptoms and fertility issues are prevalent and demand special focus.

RESUMO

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.

RESUMO

Background: Treatment of malignant melanoma has undergone a paradigm shift with the advent of immune checkpoint inhibitors (ICI) and targeted therapies. However, access to ICI is limited in low-middle income countries (LMICs). Patients and Methods: Histologically confirmed malignant melanoma cases registered from 2013 to 2019 were analysed for pattern of care, safety, and efficacy of systemic therapies (ST). Results: There were 659 patients with a median age of 53 (range 44-63) years; 58.9% were males; 55.2% were mucosal melanomas. Most common primary sites were extremities (36.6%) and anorectum (31.4%). Nearly 10.8% of the metastatic cohort were BRAF mutated. Among 368 non-metastatic patients (172 prior treated, 185 de novo, and 11 unresectable), with a median follow-up of 26 months (0-83 months), median EFS and OS were 29.5 (95% CI: 22-40) and 33.3 (95% CI: 29.5-41.2) months, respectively. In the metastatic cohort, with a median follow up of 24 (0-85) months, the median EFS for BSC was 3.1 (95% CI 1.9-4.8) months versus 3.98 (95% CI 3.2-4.7) months with any ST (HR: 0.69, 95% CI: 0.52-0.92; P = 0.011). The median OS was 3.9 (95% CI 3.3-6.4) months for BSC alone versus 12.0 (95% CI 10.5-15.1) months in any ST (HR: 0.38, 95% CI: 0.28-0.50; P < 0.001). The disease control rate was 51.55%. Commonest grade 3-4 toxicity was anemia with chemotherapy (9.5%) and ICI (8.8%). In multivariate analysis, any ST received had a better prognostic impact in the metastatic cohort. Conclusions: Large real-world data reflects the treatment patterns adopted in LMIC for melanomas and poor access to expensive, standard of care therapies. Other systemic therapies provide meaningful clinical benefit and are worth exploring especially when the standard therapies are challenging to administer.

RESUMO

Coronavirus pandemic has increased human disease burden, as well as economic distress globally. Being in an immunocompromised state, patients with cancer comprise an important at-risk population for novel coronavirus disease 2019 (COVID-19) infection. It is necessary to modify individualized clinical management for every cancer patient in the context of the ongoing COVID-19 pandemic. Simultaneously, additional safety precautions for the cancer care providers are mandatory. This review will provide general recommendations in the Indian context optimizing the same.

RESUMO

Coronavirus infection or COVID 19 was first reported in December 2019 in Wuhan, China, and has rapidly spread to more than 200 countries. The pandemic has also taken a toll of over 2.2 million. But the elusive search for an effective antidote is still on. Pending multiple and robust randomized controlled studies, some drugs are being used globally based on in-vitro studies, in -vivo evidence, observational studies, and small nonrandomized studies. Remdesivir is a nucleotide analog. It inhibits viral RNA-dependent RNA polymerase enzyme. Several studies have hitherto demonstrated the promising in-vitro and in-vivo antiviral activities of the molecule against severe acute respiratory syndrome coronavirus (SARS-CoV-1) and the Middle East respiratory syndrome coronavirus (MERS-CoV) strains. It has now exhibited potential in vitro activity against SARS-CoV-2 strains too. Based on pivotal studies, remdesivir is now being used to treat moderate to severe patients through emergency use authorizations and other access programs around the world. This review aims to summarize the evidence and clinical trials of remdesivir as a potential therapeutic option for COVID-19.

RESUMO

BACKGROUND: There is scant data from India on efficacy and safety of palbociclib and ribociclib in routine clinical practice. METHODS: This retrospective, observational, single institution study included patients with estrogen and/or progesterone receptor positive and human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancers, who received palbociclib or ribociclib with any partner endocrine therapy in any line of treatment between January 2016 and June 2019. Data were analyzed for progression-free survival (PFS), overall survival (OS) and toxicity. RESULTS: The study included 101 female patients with median age of 57 (IQR 48-62) years, of whom 80 (79.2%) were postmenopausal, 79 (78.2%) received palbociclib or ribociclib in second- or later-line treatment, 59 (58.4%) received fulvestrant and 41 (40.6%) received an aromatase inhibitor. In first-line treatment, at a median follow-up of 21.7 (0.5-41.9) months, median PFS and OS were 21.1 (95%CI 16.36-not estimable) months and not reached, respectively. In second- or later-line setting, at a median follow-up of 17.2 (0.5-43.7) months, median PFS and OS were 5.98 (95%CI 4.96-7.89) months and 20.2 (95%CI 14.1-not estimable) months, respectively. Grade 3-4 neutropenia and febrile neutropenia were seen in 45 (45.0%) and 9 (9.0%) patients, respectively while dose reduction was required in 32 (31.7%) patients. In multivariable Cox regression analysis, first-line setting (HR 0.49, 95%CI 0.25-0.97, p = 0.043) and ECOG performance status 1 (HR 0.43, 95%CI 0.20-0.91, p = 0.028) were significantly associated with PFS while only ECOG PS 1 was significantly associated (HR 0.04, 95%CI 0.008-0.206, p = 0.000) with OS. CONCLUSION: Palbociclib and ribociclib, when used in routine clinical practice in first or subsequent lines of treatment, resulted in efficacy and toxicity outcomes in concordance with those expected from pivotal trials.

RESUMO

IMPORTANCE: The Cancer Aging Research Group (CARG) toxicity score is used to assess toxicity risk in geriatric patients receiving chemotherapy. OBJECTIVE: The primary aim was to validate the CARG score in geriatric patients treated with curative intent chemotherapy in predicting grade 3-5 toxicities. DESIGN: This was a longitudinal prospective observational study. SETTING: Tata Memorial Hospital, Mumbai, India, a tertiary cancer care referral centre. PARTICIPANTS: Patients, aged ≥65 years, with gastrointestinal, breast or gynaecological stage I-III cancers being planned for curative intent chemotherapy. A total of 270 patients were required for accrual in the study. EXPOSURES: Total risk score ranged from 0 (lowest toxicity risk) to 19 (highest toxicity risk). MAIN OUTCOMES AND MEASURES: The primary endpoint of the study was to evaluate whether the CARG risk score predicted for grade 3-5 toxicities. RESULTS: The study cohort of 270 patients had a mean age of 69 (65-83) years, with the most common cancers being gastrointestinal (79%). Fifty-two per cent of patients had atleast one grade 3-5 toxicity. The risk of toxicity was increased with an increasing risk score (42% low risk, 51% medium risk and 79% high risk; p<0.001). There was no association between either Eastern Cooperative Oncology Group (ECOG) performance status (p=0.69) or age-adjusted Charlson Comorbidity Index (p=0.79) risk categories and grade 3-5 chemotherapy toxicities. CONCLUSIONS AND RELEVANCE: This study validates the CARG risk score in predicting for grade 3-5 toxicities in geriatric oncology patients receiving curative intent chemotherapy and can be considered as the standard of care before planning chemotherapy in every elderly patient.

RESUMO

BACKGROUND: Outcome and toxicity data in adolescent-adult Ewing sarcoma (AA-ES) patients are sparse and merits exploration. METHODS: Histopathologically confirmed, nonmetastatic AA-ES patients, who received standard institutional combination chemotherapy regimen (Ewing's family of tumors-2001 [EFT-2001]) comprising of ifosfamide plus etoposide and vincristine, doxorubicin plus cyclophosphamide, lasting a total of 12 months between 2013 and 2018, were analyzed for treatment-related toxicities, event-free survival (EFS), and overall survival (OS). RESULTS: There were 235 patients (primary safety cohort [PSC]) with median age of 23 (15-61) years; 159 (67.7%) were males, 155 (65.9%) had skeletal primary and 114 (48.5%) had extremity tumors. One hundred ninety-six (83.4%) were treatment naïve (primary efficacy cohort [PEC]) and of these 119 (60.7%) had surgery. In PEC, at a median follow-up of 36.4 (interquartile range [IQR] 20-55) months, estimated 3-year EFS and OS were 67.3% (95% CI 60.3-75.1%) and 91.1% (95% CI 86.7-95.7%), respectively. Of these, 158 (80.6%) complying with intended treatment, at a median follow-up of 39 (IQR 26-57) months had an estimated 3-year EFS of 68.2% (95% CI 60.3-76.1%). In multivariable analysis, good prognostic factors included longer symptom(s) duration (HR 0.93, 95% CI 0.86-0.994), ≥99% necrosis (HR 0.30, 95% CI 0.11-0.77), and treatment completion (HR 0.32, 95% CI 0.14-0.74). Among PSC, grade 3-4 toxicities were febrile neutropenia (119, 50.6%), anemia (130, 55.3%), peripheral neuropathy (37, 15.7%), with three (1.3%) chemo-toxic deaths. CONCLUSIONS: The outcomes of AA nonmetastatic ES patients treated with EFT-2001 regimen were comparable to those reported by others, with acceptable toxicity. This regimen can be considered a standard of care in AA-ES.

RESUMO

Melanocytic schwannoma (MS) is a rare nerve sheath tumour characterised by melanin-producing neoplastic schwann cells that typically affects the posterior spinal nerve roots. We report an ultrarare case of recurrent/metastatic MS associated with Carney complex in a young woman with family history of breast cancer. This highlights the novel approach of combined checkpoint inhibitors (CPI) and radiotherapy. The patient was initially treated with Nivolumab along with concurrent external beam radiotherapy. There was sustained clinical benefit achieved for over 15 months with preserved quality of life. Addition of Ipilimumab, which she tolerated reasonably well, helped to control the progressive disease again for another 12 months. She harboured a rare PRKAR1A R228 mutation (Carney complex) and received appropriate targeted therapy. She survived for 51 and 35 months from her initial diagnosis and start of CPI, respectively, which to the best of our knowledge is the longest documented survival in this rare entity.

RESUMO

Background: Diabetes mellitus is associated with increased rate of respiratory tract infections. The objective was to compare demographic, clinical, serum biochemical, and typical and atypical radiological profiles among hospitalized diabetics and nondiabetics with lower respiratory tract infection. Material and Methods. A prospective, hospital-based, consecutive, comparative observational study of 12-month study duration was conducted. Patients aged 13-90 years diagnosed with lower respiratory tract infection with or without diagnosed diabetes mellitus participated in the study. Demographic, clinical, serum biochemistry, and radiological profiles of diabetics (n = 44) and nondiabetics (n = 53) were compared. Results: Diabetics were older than nondiabetics at presentation (p < 0.0001). Difference in mean random blood sugar (RBS) (p < 0.001), fasting blood sugar (FBS) (p < 0.001), and postprandial blood sugar (PPBS) (p < 0.0001) was significant between diabetics and nondiabetics. Nondiabetics more frequently presented with fever (p = 0.0032), chest pain (p = 0.0002), and hemoptysis (p = 0.01) as compared to diabetics. Diabetics more frequently presented with extreme temperatures (hypothermia or hyperpyrexia) (p = 0.022), lower serum sodium levels (p = 0.047), and lower partial arterial pressure (p < 0.001) than nondiabetics. The mean pneumonia patient outcomes research team (PORT) risk score was higher in diabetics (124.84 ± 41.31) compared to nondiabetics (77.85 ± 39.77) (p < 0.001). Diabetics more commonly displayed bilateral lesions with multilobe or lower lobe involvement, the most common type of lesion being exudative. Conclusion: Diabetic patients usually had severe pulmonary infection and poor prognosis as suggested by higher mean PORT risk score. They also more frequently presented with bilateral lesions with multilobe or lower lobe involvement as evidenced by radiography as compared to nondiabetic patients.

RESUMO

Background: There is limited access to 1 year of adjuvant trastuzumab in resource-constrained settings. Most randomized studies have failed to prove non-inferiority of shorter durations of adjuvant trastuzumab compared to 1 year However, shorter durations are often used when 1 year is not financially viable. We report the outcomes with 12 weeks of trastuzumab administered as part of curative-intent treatment. Methods: This is a retrospective analysis of patients treated at Tata Memorial Centre, Mumbai, a tertiary care cancer center in India. Patients with human epidermal growth factor receptor (HER2)-positive early or locally advanced breast cancer who received 12 weeks of adjuvant or neoadjuvant trastuzumab with paclitaxel and four cycles of an anthracycline-based regimen in either sequence, through a patient assistance program between January 2011 and December 2012, were analyzed for disease-free survival (DFS), overall survival (OS), and toxicity. Results: A total of 102 patients were analyzed with a data cutoff in September 2019. The median follow-up was 72 months (range 6-90 months), the median age was 46 (24-65) years, 51 (50%) were postmenopausal, 37 (36%) were hormone receptor-positive, and 61 (60%) had stage-III disease. There were 37 DFS events and 26 had OS events. The 5-year DFS was 66% (95% Confidence Interval [CI] 56-75%) and the OS was 76% (95% CI 67-85%), respectively. Cardiac dysfunction developed in 11 (10.7%) patients. Conclusion: The use of neoadjuvant or adjuvant 12-week trastuzumab-paclitaxel in sequence with four anthracycline-based regimens resulted in acceptable long-term outcomes in a group of patients, most of whom had advanced-stage nonmetastatic breast cancer.

RESUMO

Background: In metastatic soft tissue sarcoma (M-STS), pazopanib has demonstrated promising activity; however, there is dearth of data from lower and middle income countries. It is important to explore the feasibility (toxicity, acceptance), efficacy (response rates, survival), and optimal dose requirement of pazopanib in M-STS in India. Methods: All patients who received pazopanib for M-STS in 2013-2018 in Tata Memorial Centre were included. Institutional ethics committee approval was obtained. Assessment for response with contrast computed tomography scans was done as per the response evaluation criteria in solid tumors (RECIST) 1.1 criteria. Pazopanib was continued until progression or unacceptable toxicity. Clinical benefit rates and survival were evaluated by Kaplan-Meier method. All statistical calculations were done using SPSS version 21.0. Results: Seventy-two consecutive patients with a median follow-up of 17 (4-40) months were included in this study. Median lines of prior therapy were 2 (0-2). Among 50 evaluable patients, there were 12/50 (24%) partial responses, 25/50 (50%) stable disease, and 15/50 (30%) progressive disease. Median progression-free survival was 5 (95% confidence interval (CI) 3-6.9) months and median overall survival was 11 (95% CI 6.8-15.2) months. Adverse effects (G2/G3) in patients: hand foot syndrome-28%, hyperbilirubinemia/transaminitis-10%, diarrhea-20%, hypertension-17%, hypothyroidism-15%, anemia-6%, and fatigue-17%. Notably, 40% patient required dose reduction and median dose was 600 (200-800) mg daily. Conclusion: Pazopanib was found a feasible treatment option for M-STS in India with internationally comparable outcomes. However, significant patients required dose modifications, and median tolerated dose was lower than the standard 800 mg dose. This novel finding merits confirmation in larger cohorts for reproducibility.

RESUMO

BACKGROUND: Pregnancy associated breast cancer (PABC) is a rare entity and defined as breast cancer diagnosed during pregnancy or one-year post-partum. There is sparse data especially from low and middle-income countries (LMIC) and merits exploration. METHODS: The study (2013-2020) evaluated demographics, treatment patterns and outcomes of PABC. RESULTS: There were 104 patients, median age of 31 years; 43 (41%) had triple-negative disease, 31(29.8%) had hormone-receptor (HR) positive and HER2 negative, 14 (13.5%) had HER2-positive and HR negative and 16(15.4%) had triple positive disease. 101(97%) had IDC grade III tumors and 74% had delayed diagnosis. 72% presented with early stage (24, EBC) or locally advanced breast cancer (53, LABC) and received either neoadjuvant (n = 49) or adjuvant (n = 26) chemotherapy and surgery. Trastuzumab, tamoxifen, and radiotherapy were administered post-delivery. At a median follow up of 27 (IQR:19-35) months, the estimated 3-year event-free survival (EFS) for EBC and LABC was 82% (95% CI: 65.2-100) and 56% (95% CI: 42-75.6%) and for metastatic 24% (95% CI: 10.1%-58.5%) respectively. Of the 104 patients, 34 were diagnosed antepartum (AP) and 15 had termination, 2 had preterm and 16 had full-term deliveries(FTDs). Among postpartum cohort (n = 70), 2 had termination, 1 had preterm, 67 had FTDs. 83(including 17 from AP) children from both cohorts were experiencing normal milestones. CONCLUSION: Data from the first Indian PABC registry showed that the majority had delayed diagnosis and aggressive features(TNBC, higher grade). Treatment was feasible in majority and stage matched outcomes were comparable to non-PABCs.

RESUMO

Purpose: About 30%-35% of nonmetastatic and 60%-80% of metastatic Ewing Sarcoma (ES) will relapse post-treatment and outcomes after relapse continue to be poor over last several decades. Prognostic factors affecting survival after relapse of ES are also not robustly known. We present outcomes using a novel hybrid salvage protocol of four active chemotherapeutic agents in our cohort of patients after relapse of ES. Methods: This is a retrospective analysis of all consecutive relapsed ES patients treated with curative intent over 4 years (January 2012 to December 2015). All received 12-cycles of hybrid chemotherapy regimen with surgery/radiotherapy done after first 4 cycles. Event-free survival (EFS)/overall survival (OS) estimates were analyzed by Kaplan-Meier product-limit estimator. Cox regression analysis was performed to identify prognostic factors predicting outcome in relapsed ES. Results: Salvage regimen was given to 53/108 relapsed ES patients with the rest having opted for palliation upfront. Median age of the treated patients was 19 years (range: 4-40); male:female ratio was 2.7:1. Median time to first relapse was 18.8 months (range: 2.2-91). While 41/53 patients (77%) completed salvage therapy, 6 (11.3%) progressed and 6 (11.3%) abandoned treatment. Median follow-up of the study cohort is 31 months (range: 4-81). Of the analyzable cohort (n = 47), 30 (64%) had a second relapse or progression on salvage treatment. At last follow-up, 31 patients had died (including one due to toxicity and rest due to disease) and 16 patients were alive (14 with no active disease and 2 with disease). The 4-year EFS and OS are 28% and 37%, respectively, for the entire cohort. While adolescents and young adult patients (AYA) had a better survival (p-0.041), relapsed ES patients with shorter disease-free interval (DFI) (<24 months) had a poorer survival (p-0.004). The type of relapse (local or metastatic or combined) after primary treatment did not affect outcome after salvage therapy. Conclusions: We have used a novel hybrid chemotherapy protocol using four active agents in relapsed ES, which is well tolerated and shows promising results. Older age (≥15 years) and longer DFI (>24 months) portend better survival post-relapse. In our cohort of relapsed ES, AYAs fared better than others and type of relapse after primary treatment did not affect outcome after salvage therapy.

RESUMO

COVID 19 infection is unarguably the worst pandemic of this century. Till date there is no promising drug and vaccine available to treat this deadly viral infection. In the early phase chloroquine phosphate and hydroxychloroquine sulphate have been used to fight this illness on the basis of handful observational and small randomized and small-randomized studies. The paucity of clinical evidences of an unequivocal beneficial effect of chloroquine and hydroxychloroquine on COVID-19 has resulted in the passionate use of the drug for moderate to severe cases only and stimulated the need for large clinical trials for this and other molecules. In this review, we describe in brief the mechanism of action, the clinical studies, factors for cardiac toxicity, guidelines and future directions for hydroxychloroquine use in management of COVID-19 infection.

RESUMO

Behcet's disease (BD) is clinically characterized by recurrent oral and genital ulcers and ocular symptoms. However, systemic manifestations involving the lungs, gastrointestinal tract, kidneys, and heart are well known. Acute myocardial infarction (MI) is a rare manifestation of Behcet's syndrome and usually results from coronary arteries vasculitis, leading to aneurysms. More uncommon is the occurrence of acute MI as the initial presenting symptom. Hereby, we report a case of a young male who presented with acute anterior wall MI sans any other conventional risk factors with a normal angiogram. And 3 years later, he was diagnosed with BD.
