RESUMEN

With improvement in survival after chronic lymphocytic leukemia (CLL) diagnosis, the real-world burden of second hematological malignancies (SHM) has not been comprehensively assessed in recent era. We analyzed risk, incidence, and outcomes of SHM in CLL patients between 2000 and 2019 using SEER database. CLL patients had greater risk for hematological malignancies than general population [SIR, standardized incidence ratio (95% CI):2.58 (2.46-2.70); p < 0.05]. The risk for subsequent lymphoma increased by 1.75 folds in 2015-2019 compared to 2000-2004. The duration, after CLL diagnosis, of maximum risk for SHM decreased as 60-119 months for time-period 2000-2004, 6-11 months for 2005-2009 to 2-5 months for 2010-2014 and 2015-2019. Incidence of SHM was 2.5% in CLL survivors (1736/70,346) with lymphoid SHM being more common than myeloid SHM, and DLBCL being the most common pathology (n = 610, 35% of all SHM). Male sex, age ≤65 years at CLL diagnosis, and chemotherapy treatment were associated with higher risk for SHM. The median gap between CLL and SHM diagnoses was 46 months. The median survival for de-novo-AML, t-MN, CML, and aggressive NHL was 63, 86, 95, and 96 months respectively. Although SHM remains rare, there is increased risk in recent era, likely due to improved survival in CLL patients, necessitating active surveillance strategies.

RESUMEN

BACKGROUND: Ki-67 is an index of proliferative activity and is an established predictive and prognostic marker in multiple malignancies. However, its prognostic relevance in multiple myeloma (MM) is unclear. We investigated the relationship between Ki-67 expression and survival outcomes in MM in the era of novel therapies. METHODS: We interrogated our database to identify patients with MM, newly diagnosed between July 1, 2013 and December 31, 2020, with Ki-67 expression assessed by immunohistochemistry (IHC) on bone marrow biopsies. Using an established threshold of 5% we defined Ki-67low (≤5%) and Ki-67high (>5%) subgroups for association with progression-free survival (PFS) and overall survival (OS). RESULTS: Of 167 patients included: 53 (31.7%) had Ki-67high and 114 had Ki-67low. More patients with R-ISS 3 had Ki-67high (22.2% vs. 9.7%). The gain of 1q21 was overrepresented in the Ki-67high group (28% vs. 8%). Median PFS in the Ki-67low group was 3.1 years, and in the Ki-67high group 1.6 years (log-rank p < .001, HR: 1.9). Median OS was not reached in the Ki-67low vs. 4.8 years in the Ki-67high cohort (HR: 1.9; log-rank test: p = .018). In the multivariable modeling, after adjusting for other risk factors, HR for Ki-67high versus Ki-67low was 2.4 (p < .001) for PFS and 2.1 (p = .026) for OS. CONCLUSIONS: Our results demonstrate that a high Ki-67 index (>5%) is an independent prognostic marker associated with worse OS and PFS in newly diagnosed MM. IHC staining for Ki-67 on bone marrow biopsies could be easily adopted as a prognostic biomarker for MM in economically constrained healthcare settings.

RESUMEN

Chimeric antigen receptor (CAR) T-cell is the most recent version in the evolution of cellular therapy with promising responses, which has revolutionized the management of some hematological malignancies in the current times. As the clinical use has progressed rather rapidly since the first approval in 2017, toxicities beyond cytokine release syndrome and immune effector cell-associated neurological syndrome have surfaced. Cytopenias are common in <30 days ("early"), 30-90 days ("short-term") as well as >90 days ("prolonged"); and have clinical implications to patient care as well as resource utilization. We review the details of etiology, factors associated with cytopenias, and management considerations for patients with cytopenias for each of these time-frames. This would potentially serve as a clinical guide for hematological toxicity or CAR-T-OPENIA, which is commonly encountered with the use of CAR T-cell therapy.

RESUMEN

INTRODUCTION: Recent advances in the diagnosis and management of multiple myeloma (MM) have improved patient outcomes. This progress in our understanding of MM has resulted in continuous suppressive therapy concepts, including induction, high dose chemotherapy with autologous stem cell transplantation (ASCT), consolidation, and maintenance therapy. The foundation of maintenance therapy has been with lenalidomide. Other novel immunomodulatory drugs (IMiDs), proteasome inhibitors (PIs), and targeted monoclonal antibodies have also contributed to this evolution. AREAS COVERED: This review summarizes the outcomes from phase II/III trials with long-term lenalidomide maintenance therapy alone or in combination with other agents in post-ASCT and non-transplant settings for newly diagnosed patients with MM. We review recent data considering a combination with newer medications and ongoing trials. We also review the optimal duration, MRD negativity rate, and safety and tolerability aspects of lenalidomide maintenance therapy. This review aims to present the current and emerging clinical evidence that supports using lenalidomide as a backbone for maintenance therapy in patients with MM. EXPERT OPINION: There is increasing evidence to support lenalidomide as the backbone of combination therapy in the maintenance setting.

RESUMEN

OBJECTIVE: Primary renal lymphoma (PRL) is defined as a non-Hodgkin lymphoma (NHL) restricted to kidneys without extensive nodal disease. The literature on epidemiology and outcome in PRL is limited to case reports and small case series. METHODS: We utilized Surveillance, Epidemiology, and End Result database (1984-2015) to study the demographic, clinical, and pathological characteristics of PRL. We conducted analysis to assess factors associated with overall survival (OS) and cause-specific survival (CSS). RESULTS: A total of 599 (0.17% of all NHL) patients were eligible for the study. The age-adjusted incidence was 0.035/100,000 population and is increasing. The median age was 72 years, and most of the patients were Caucasians and were males. Most of the patients had unilateral tumors, and diffuse large B-cell lymphoma (DLBCL) was the most common histologic type. The median OS was 112 months, while median CSS was not reached. Age ≥ 60 years was the strongest independent risk factor for worse OS and CSS, while non-DLBCL histology was associated with better OS and CSS. DISCUSSION: Primary renal lymphoma is a rare lymphoma with increasing incidence in more recent years. In this study, we describe demographic, clinical, and pathological characteristics of PRL and factors affecting survival among these patients.

RESUMEN

BACKGROUND: Hydroxyurea, chronic blood transfusions, and bone marrow transplantation are efficacious, disease-modifying therapies for sickle cell disease but involve complex risk-benefit trade-offs and decisional dilemma compounded by the lack of comparative studies. A patient decision aid can inform patients about their treatment options, the associated risks and benefits, help them clarify their values, and allow them to participate in medical decision making. OBJECTIVE: The objective of this study was to develop a literacy-sensitive Web-based patient decision aid based on the Ottawa decision support framework, and through a randomized clinical trial estimate the effectiveness of the patient decision aid in improving patient knowledge and their involvement in decision making. METHODS: We conducted population decisional needs assessments in a nationwide sample of patients, caregivers, community advocates, policy makers, and health care providers using qualitative interviews to identify decisional conflict, knowledge and expectations, values, support and resources, decision types, timing, stages and learning, and personal clinical characteristics. Interview transcripts were coded using QSR NVivo 10. Alpha testing of the patient decision aid prototype was done to establish usability and the accuracy of the information it conveyed, and then was followed by iterative cycles of beta testing. We conducted a randomized clinical trial of adults and of caregivers of pediatric patients to evaluate the efficacy of the patient decision aid. RESULTS: In a decisional needs assessment, 223 stakeholders described their preferences, helping to guide the development of the patient decision aid, which then underwent alpha testing by 30 patients and 38 health care providers and iterative cycles of beta testing by 87 stakeholders. In a randomized clinical trial, 120 participants were assigned to either the patient decision aid or standard care (SC) arm. Qualitative interviews revealed high levels of usability, acceptability, and utility of the patient decision aid in education, values clarification, and preparation for decision making. On the acceptability survey, 72% (86/120) of participants rated the patient decision aid as good or excellent. Participants on the patient decision aid arm compared to the SC arm demonstrated a statistically significant improvement in decisional self-efficacy (P=.05) and a reduction in the informed sub-score of decisional conflict (P=.003) at 3 months, with an improvement in preparation for decision making (P<.001) at 6 months. However, there was no improvement in terms of the change in knowledge, the total or other domain scores of decisional conflicts, or decisional self-efficacies at 6 months. The large amount of missing data from survey completion limited our ability to draw conclusions about the effectiveness of the patient decision aid. The patient decision aid met 61 of 62 benchmarks of the international patient decision aid collaboration standards for content, development process, and efficacy. CONCLUSIONS: We have developed a patient decision aid for sickle cell disease with extensive input from stakeholders and in a randomized clinical trial demonstrated its acceptability and utility in education and decision making. We were unable to demonstrate its effectiveness in improving patient knowledge and involvement in decision making.

RESUMEN

Being inherently different from any other lifesaving organ transplant, uterine transplantation does not aim at saving lives but supporting the possibility to generate life. Unlike the kidneys or the liver, the uterus is not specifically a vital organ. Given the non-lifesaving nature of this procedure, questions have been raised about its feasibility. The ethical dilemma revolves around whether it is worth placing two lives at risk related to surgery and immunosuppression, amongst others, to enable a woman with absolute uterine factor infertility to experience the presence of an organ enabling childbirth. In the year 2000, the first uterine transplantation, albeit unsuccessful, was performed in Saudi Arabia from where it has spread to the rest of the world including Sweden, the United States and now recently India. The procedure is, however, still in the preclinical stages and several ethical, legal, social and religious concerns are yet to be addressed before it can be integrated into the clinical setting as standard of care for women with absolute uterine factor infertility.

RESUMEN

Abortion continues to be a moral and ethical dilemma in medicine. While abortions in general have always faced social stigmas, the abortion of fetuses with Down's syndrome in particular remains the subject of debate across the globe. In India, under the Medical Termination of Pregnancy Act, abortion is legal under prescribed circumstances only till 20 weeks of gestation. Laws for abortion after 20 week of gestation are ill defined. In a recent ruling of the Supreme Court in India, a woman was denied the right to abortion of her 26 week old fetus. With this ruling, India has joined the rest of the world in the debate surrounding abortion laws and the ethics of abortion.

RESUMEN

Childhood cancers form a rare and heterogeneous group which fortunately have a higher cure rate than adult cancers. A few non-profit organizations in Nepal have extended support to help patients suffering from cancer, but their main focus has been on adults. The objective of this study was to establish the pattern of childhood cancers in the Western region of Nepal. We reviewed cases receiving external radiotherapy with both palliative and curative intent between 28th September 2010 and 30th September 2015 at the Department of Radiotherapy and Oncology, Manipal Teaching Hospital affiliated with Manipal College of Medical Sciences, Pokhara, Nepal. Of the total of 1217 cases, 2.71% involved children. The gender distribution showed a male preponderance (M:F= 1.35:1). The patients' mean age was 11.4 years (range 2 - 14 years). Considering the caste, Brahmins and Gurungs constituted 33.0% and 21.2%, respectively, of children with cancer.
