A randomized trial of ibrutinib and R-GDP prior to stem cell transplant in relapsed diffuse large B-cell lymphoma.

In the LY.17 randomized phase II clinical trial, adults with relapsed and refractory diffuse large B-cell lymphoma treated with ibrutinib-R-GDP (IR-GDP) for up to three cycles had more documented bacterial and fungal infections, without improvement in overall response, compared with R-GDP. CR, complete response; DLBCL, diffuse large B-cell lymphoma; PD, progressive disease; PR, partial response; R/R, relapsed/refractory; SD, stable disease.

Impact of universal hepatitis B virus (HBV) screening using chemotherapy orders on the HBV reactivation in cancer patients.

INTRODUCTION: Hepatitis B virus (HBV) reactivation (HBVr) induced by chemotherapy in patients with resolved or chronic infection can lead to severe consequences. Despite recommendations, rates of HBV screening before chemotherapy are low due to poor recognition of risk factors by clinicians. The aim of the study is to assess whether routine HBV screening using universal HBV screening on chemotherapy orders (CO) could reduce HBVr incidence. METHODS: This is a 1-year retrospective single-center observational study of patients who received intravenous chemotherapy post implementation of CO. We compared the incidence of HBVr in three groups of patients: those screened through CO (group 1), those screened by the medical team (group 2), and those not screened (group 3). RESULTS: On a total of 1374 patients, 179 of 206 patients were screened as requested on CO (group 1) and 421 by the medical team (group 2), whereas 747 patients were not screened (group 3). Only one HBVr occurred, and no difference was seen on the incidence of HBVr between group 1 and group 3 (0% vs 0.1%; p = 1.00), probably because of a lack of follow-up after chemotherapy. Follow-up for HBVr was imperfect in group 1 and group 2 (16.7% vs 5.6%; p = 0.32). Screening was done for 92% of patients on anti-CD20 therapy. In group 3, 89 patients had ALT elevation during chemotherapy but only 17 (19%) were tested for HBVr. CONCLUSION: Systematic HBV detection requested on CO is an effective way to obtain a high percentage of patients with adequate screening, particularly when chemotherapy is at high risk of HBVr. Nevertheless, this screening method do not guarantee optimal follow-up and requires improvements.

Risks of hepatitis C virus reactivation in a real-life population of oncology patients treated in an academic center.

BACKGROUND: Chemotherapy has been associated with a theoretical risk of hepatitis C virus (HCV) reactivation. However, little is known about the amplitude of viral replication and the incidence of subsequent hepatic exacerbation. METHOD: We aimed to describe the occurrence of hepatitis flare and HCV reactivation at our center. We included, over a period of 5 years, adult patients with chronic HCV receiving intravenous chemotherapy. We excluded patients with undetectable HCV RNA, hepatocellular carcinoma, liver metastases or other etiologies of hepatic disease. The primary objective was to identify hepatic flares (elevation of alanine aminotransferase 3 times above the upper limit of normal). Secondary objectives were to assess viral reactivation (HCVr, HCV-RNA ≥1 log10 IU/mL when compared to baseline value), hepatic decompensation, mortality and the impact on the chemotherapy. Descriptive statistics were used. RESULTS: A total of 11 patients with chronic HCV were identified among the 5761 oncology patients. Five patients experienced a hepatic flare with median maximal ALT value of 139 U/L (IQR 133-237). Only 2 patients met criteria for HCVr with a median RNA increase of 1.16 log IU/mL (IQR 1.1-1.2). One patient presented with both HCVr and a hepatic flare. Only one patient required chemotherapy discontinuation following hepatic flare. No hepatic decompensation or related mortality were observed. CONCLUSION: We identified a very small number of HCV cases among our population. We observed HCVr and hepatic flares, but only one consequence on cancer treatment. Nonetheless, HCV screening is encouraged among patients undergoing chemotherapy to allow close follow-up of hepatic function.

From theory to practice: implementing a standardized, interactive education session on oral anticancer medication (OAM) for patients and their caregivers.

PURPOSE: Self-administration at home and decreased visits to see health care professionals bring patients on oral anticancer medication (OAM) and their caregivers to become experts in handling medication, managing adverse events, and making sure that they adhere to treatment. This project aimed to implement a standardized education group session for patients starting an OAM regimen and their caregivers that would build new knowledge, validate comprehension of information, increase satisfaction, and empower participants in self-management. MATERIALS AND METHODS: A group session led by an oncology nurse was developed. The theoretical section consisted of short videos that include both verbal and visual explanations. The practical component consisted of quizzes with electronic recordings and instant answers. Turning Point technology was used to compile and analyze the data. RESULTS: Over a 2-year period, 124 patients and 79 caregivers participated in the group sessions. More than 111 h were saved by giving standardized group sessions instead of individual teachings. The participants' level of confidence regarding the essential concepts to master significantly increased following the group sessions. The results ranged from 18% of participants who answered 4 or 5 on a five-point Likert-type scale before the session to 100% who answered 4 or 5 after the group session. 94% of participants responded with a rating of 4 or 5 when asked if they were satisfied with the overall interactive group session. CONCLUSION: It is crucial that caregivers participate in the initial OAM teaching. The involvement of the interdisciplinary team was crucial in meeting the informational needs of patients. A standardized group session accessible for viewing and use by all health care professionals and patients simplifies the process of sharing high-quality learning materials in a technological society.

Primary central nervous system lymphoma.

Primary central nervous system lymphoma (PCNSL) comprises approximately 5 % of all primary brain tumors. During the past two decades the incidence of PCNSL has increased, and as a result clinical research to determine the optimal treatment for PCNSL patients also has increased. Diagnosis is based on histopathologic findings traditionally established by biopsy only. More recent data raise controversy and challenges this biopsy-only paradigm, showing a potential advantage for surgical resection with progression-free survival (PFS) and overall survival (OS). Using high-dose intravenous (IV) methotrexate-based chemotherapy alone or as part of a regimen can lead to disease cure. The role of whole brain radiotherapy (WBRT) remains controversial and more frequently is omitted to avoid potential delayed neurocognitive effects, especially in patients older than age 60 years. Newer data from Memorial Sloan Kettering Cancer Center (MSKCC) using five cycles of Rituximab, Methotrexate, Vincristine, and Procarbazine (R-MVP) followed by low-dose WBRT (2,340 cgy), and then two cycles of Ara-C had excellent disease control with low neuro-toxicity and is now the basis of an ongoing RTOG (Radiation Treatment Oncology Group) trial comparing early versus delayed WBRT. Other chemotherapeutics and novel treatments, such as autologous stem cell transplantation, are being studied for potential use in PCNSL. Unlike many other primary brain tumors seen in adults, PCNSL is potentially curable; therefore, balancing treatment decisions with long-term neurocognitive effects and toxicities is crucial.

High mortality among hospital-acquired COVID-19 infection in patients with cancer: A multicentre observational cohort study.

INTRODUCTION: Studies suggest that patients with cancer are more likely to experience severe outcomes from COVID-19. Therefore, cancer centres have undertaken efforts to care for patients with cancer in COVID-free units. Nevertheless, the frequency and relevance of nosocomial transmission of COVID-19 in patients with cancer remain unknown. The goal of this study was to determine the incidence and impact of hospital-acquired COVID-19 in this population and identify predictive factors for COVID-19 severity in patients with cancer. METHODS: Patients with cancer and a laboratory-confirmed diagnosis of COVID-19 were prospectively identified using provincial registries and hospital databases between March 3rd and May 23rd, 2020 in the provinces of Quebec and British Columbia in Canada. Patient's baseline characteristics including age, sex, comorbidities, cancer type and type of anticancer treatment were collected. The exposure of interest was incidence of hospital-acquired infection defined by diagnosis of SARS-CoV-2 ≥ 5 days after hospital admission for COVID-unrelated cause. Co-primary outcomes were death or composite outcomes of severe illness from COVID-19 such as hospitalisation, supplemental oxygen, intensive-care unit (ICU) admission and/or mechanical ventilation. RESULTS: A total of 252 patients (N = 249 adult and N = 3 paediatric) with COVID-19 and cancer were identified, and the majority were residents of Quebec (N = 233). One hundred and six patients (42.1%) received active anticancer treatment in the last 3 months before COVID-19 diagnosis. During a median follow-up of 25 days, 33 (13.1%) required admission to the ICU, and 71 (28.2%) died. Forty-seven (19.1%) had a diagnosis of hospital-acquired COVID-19. Median overall survival was shorter in those with hospital-acquired infection than that in a contemporary community-acquired population (27 days versus unreached, hazard ratio (HR) = 2.3, 95% CI: 1.2-4.4, p = 0.0006. Multivariate analysis demonstrated that hospital-acquired COVID-19, age, Eastern Cooperative Oncology Group status and advanced stage of cancer were independently associated with death. INTERPRETATION: Our study demonstrates a high rate of nosocomial transmission of COVID-19, associated with increased mortality in both univariate and multivariate analysis in the cancer population, reinforcing the importance of treating patients with cancer in COVID-free units. We also validated that age and advanced cancer were negative predictive factors for COVID-19 severity in patients with cancer.
