The use of pediatrics-inspired protocols in adolescent and young adult (AYA) acute lymphoblastic leukemia (ALL) results in superior survival compared with the adult protocols. Pediatrics-inspired protocols carry an increased risk of toxicity and treatment-related mortality in low resource settings, which can offset the potential benefits. We studied the outcomes and prognostic factors in the treatment of AYA ALL with a pediatrics-inspired regimen. We retrieved data regarding demographics, investigations, treatment details, and toxicities from the electronic medical records of patients diagnosed with ALL in the 15- to 25-year-old age group who were initiated on a modified Berlin-Frankfurt-Münster 90 (BFM-90) protocol between January 2013 and December 2016 at the Tata Memorial Centre. A total of 349 patients in the 15- to 25-year-old age group were treated with a modified BFM-90 protocol. The use of this pediatrics-inspired protocol resulted in a 3-year event-free survival (EFS) and overall survival (OS) of 59.4% and 61.8%, respectively. Only 15 patients underwent an allogeneic stem cell transplant. Minimal residual disease (MRD) persistence postinduction emerged as the only factor predictive of poor outcomes. A modified BFM-90 protocol is an effective and safe regimen for AYA ALL with an OS and EFS comparable to the published literature.
Background
There is paucity of data regarding clinical characteristics, laboratory parameters and outcomes of coronavirus disease (COVID‐19) in cancer versus non‐cancer patients, particularly from India.
Materials and Methods
This was an observational, single‐centre, retrospective analysis of patients with laboratory‐confirmed COVID‐19 hospitalised in our institution between 22 May 2020 and 1 December 2020. We compared baseline clinical characteristics, laboratory parameters and outcomes of COVID‐19 (overall mortality, time to discharge) between cancer and non‐cancer patients.
Results
A total of 200 COVID‐19 infection episodes were analysed of which 109 (54.5%) were patients with cancer and 91 (45.5%) were patients without cancer. The median age was 43 (interquartile range [IQR]:32–57), 51 (IQR: 33–62) and 38 (IQR: 31.5–49.3) years; of whole cohort, cancer and non‐cancer patients, respectively. Comparison of outcomes showed that oxygen requirement (31.2% [95% CI: 22.6–40.7] vs. 17.6% [95% CI: 10.4–26.9];
p
= 0.03), median time to discharge (11 days [IQR: 6.75–16] vs. 6 days [IQR: 3–9.75];
p
< 0.001) and mortality (10.0% [95% CI: 5.2–17.3] vs. 1.1% [95% CI: 0.03–5.9];
p
= 0.017) were significantly higher in patients with cancer. In univariable analysis, factors associated with higher mortality in the whole cohort included diagnosis of cancer (10.1% vs. 1.1%;
p
= 0.027; odds ratio [OR]: 7.04), age ≥60 (17.4% vs. 2.6%;
p
= 0.001; OR: 7.38), oxygen requirement (22% vs. 0.6%;
p
< 0.001; OR: 29.01), chest infiltrates (19.2% vs. 1.4%;
p
< 0.001; OR: 22.65), baseline absolute lymphocyte count <1 × 10
9
/L (10.8% vs. 1.9%;
p
= 0.023; OR:5.1), C‐reactive protein >1 mg% (12.8% vs. 0%;
p
= 0.027; OR: 24.69), serum procalcitonin >0.05 ng/ml (22.65% vs. 0%;
p
= 0.004; OR: 4.49) and interleukin‐6 >6 pg/ml (10.8% vs. 1.3%;
p
= 0.036; OR: 3.08). In multivariable logistic regression, factors significantly associated with mortality were oxygen requirement (
p
= 0.005; OR: 13.11) and high baseline procalcitonin level (
p
= 0.014; OR: 37.6).
Conclusion
Cancer patients with COVID‐19 have higher mortality and require longer hospital stay. High procalcitonin levels and oxygen requirement during admission are other factors that affect outcomes adversely.
Although majority of cases with SARS COV-2 infection have mild symptoms or are asymptomatic, 10% patients have a severe disease. 1 As of 10th January 2021, according to current WHO data, there are 88 million cases worldwide, with 2.1% mortality rate. 2 A study from China which analysed 1590 COVID patients across 575 hospitals, showed that cancer patients are at higher risk of developing SARS-CoV-2 infection, and five times more likely to develop severe events such as use of mechanical ventilator, and death, compared to non-cancer patients. 3 Amongst cancer patients, those with hematological malignancies, who undergo HSCT and develop complications like GVHD, are even more susceptible to death from COVID-19 because of profound immunosuppression. 4 There is paucity of literature on COVID-19 in HSCT. We describe here the course and outcome of a patient who, after HSCT (complicated with extensive chronic GVHD including lung), developed severe COVID-19 and recovered completely.
Recent studies have highlighted multiple immune perturbations related to severe acute respiratory syndrome coronavirus 2 infection–associated respiratory disease [coronavirus disease 2019 (COVID‐19)]. Some of them were associated with immunopathogenesis of severe COVID‐19. However, reports on immunological indicators of severe COVID‐19 in the early phase of infection in patients with comorbidities such as cancer are scarce. We prospectively studied about 200 immune response parameters, including a comprehensive immune‐cell profile, inflammatory cytokines and other parameters, in 95 patients with COVID‐19 (37 cancer patients without active disease and intensive chemo/immunotherapy, 58 patients without cancer) and 21 healthy donors. Of 95 patients, 41 had severe disease, and the remaining 54 were categorized as having a nonsevere disease. We evaluated the association of immune response parameters with severe COVID‐19. By principal component analysis, three immune signatures defining characteristic immune responses in COVID‐19 patients were found. Immune cell perturbations, in particular, decreased levels of circulating dendritic cells (DCs) along with reduced levels of CD4 T‐cell subsets such as regulatory T cells (T

), type 1 T helper (Th1) and Th9; additionally, relative expansion of effector natural killer (NK) cells were significantly associated with severe COVID‐19. Compared with patients without cancer, the levels of terminal effector CD4 T cells, T
regs
, Th9, effector NK cells, B cells, intermediate‐type monocytes and myeloid DCs were significantly lower in cancer patients with mild and severe COVID‐19. We concluded that severely depleted circulating myeloid DCs and helper T subsets in the initial phase of infection were strongly associated with severe COVID‐19 independent of age, type of comorbidity and other parameters. Thus, our study describes the early immune response associated with severe COVID‐19 in cancer patients without intensive chemo/immunotherapy.
A 28-year-old pregnant woman in the sixth month of gestation presented with complaints of altered bowel habit for a month, on examination found to have generalised lymphadenopathy, pedal oedema and locally infiltrating ano-rectal growth. Rectal growth biopsy was reported as high-grade B-cell lymphoma. After a discussion in a multidisciplinary panel consisting of haemato-oncologists, obstetricians and physicians, she was planned to receive antenatal chemotherapy. She delivered a live baby of 1.86 kg at 36 weeks of gestational age by normal vaginal delivery. After 6 cycles of chemotherapy she had complete regression of the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
