Opinion Statement: Nurses are the "heart of patient care" and in the forefront of the health care delivery for cardio-oncology patients. Nurses play a critical central role in maximizing longitudinal health of cancer patients and survivors through the prevention of cardiovascular complications throughout the patient's cancer care journey. Nurses function in a variety of roles such as nurse clinicians, advanced practice nurses (APNs)or nurse practitioners (NPs), patient educators, managers, nurse navigators or nurse researchers. The role of nurses, particularly the advanced practice nurses as key members in delivering cardio-oncology care is evolving. However, despite the rapidly increasing growth of cardio oncology programs globally, a pivotal need remains to develop and provide formalized training programs for nurses, NPs and APNs. At present, no formal academic cardio-oncology nurse training program or certification exists. There is clearly more work to be done on the role of nurses in cardio-oncology care. As cardio-oncology evolves to become a key specialty with dedicated services being established across the globe, the role of the nurse in delivering this service is critical and a concerted collaborative approach between the two distinct specialties of cardiology and oncology needs to ensure the nursing workforce is educationally prepared and confident to treat and manage cardio-oncology patients., (© 2024.

Dasatinib is one of the second generation tyrosine kinase inhibitors (TKI) which is approved for the treatment of patients with chronic phase CML (CP-CML) both in the front line and in the second line setting. Pleural effusion (PE) is a unique toxicity associated with dasatinib use. Our aim was to study the incidence of pleural effusion in our cohort of patients who were treated with dasatinib for CP-CML and the safety upon TKI switch. A total of 390 patients were treated with dasatinib during their course of treatment for CP-CML. A total of 69 patients (17.6%) developed any grade of PE. About 33 (48%) patients developed CTCAE grade 2 PE, 34 (49%) grade 3 and only 1 patient developed grade 4 PE. Recurrence of PE was observed in 34 (49%) patients. While only 12 patients (17.3%) continued using dasatinib after development of PE, dasatinib was discontinued in the other 57 patients. Therapy was switched to bosutinib in 13 patients out of which 6 (46%) patients re-developed PE. While only 12.5% patients developed re-accumulation of pleural fluid in patients switched to imatinib, none of the patients switched to nilotinib re-developed PE. A change in TKI to bosutinib was associated with a 46% risk of recurrence of PE in patients who develop PE on dasatinib for the treatment of CP-CML. The incidence of recurrent PE was markedly lower in patient switched to imatinib or nilotinib., (© 2024. The Author(s).)

Background: Advancements in frontline therapy and chemotherapy-sparing treatments in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) have altered the treatment algorithms of this disease. We present a frontline alternative for treatment- naïve (TN) CLL/SLL patients., Methods: This was a single-center, phase 2 study of high-dose methylprednisolone (HDMP) and ofatumumab with lenalidomide and ofatumumab consolidative therapy for all comers with TN CLL/SLL. Treatment was continued until disease progression or intolerable side effects. Patients were assessed for response per iwCLL 2008 criteria after completing cycles 3 and 12., Results: Forty-five patients were enrolled (median age, 62.6 years). High-risk features included del17p (18%), Del11q (22%), and unmutated IGHV gene (76%). Median treatment duration was 32·2 (2·7-75·9) months. Thirty-six patients discontinued treatment due to disease progression (22%), adverse events (40%), allogeneic hematopoietic cell transplantation (allo-HCT) (7%), consent withdrawal (4%), and secondary malignancies (7%). The best overall and complete response rates were 96& and 29% respectively. At median follow-up of 61·7 (5·6-84·9) months, 9 patients remained on treatment. Median progression-free survival was 54·4 (2·9-77·6) months. Three patients underwent allo-HCT after a median of 3 (3-4) treatment cycles. Treatment was well tolerated, with a grade 3/4 infusion reaction in one patient. The most common grade 3/4 hematological adverse event was neutropenia (69%). Four patients had grade 3/4 infections. No grade 3/4 tumor flares, tumor lysis syndrome, or thrombosis were observed., Conclusion: The combination of ofatumumab, HDMP, and lenalidomide was effective and relatively well tolerated in treatment-naive CLL/SLL. Its role in the frontline setting remains unclear given the current available and effective treatment options., Funding: The funders had no role in the study., (Copyright © 2024 The Author(s).

Objectives: To conduct an integrative review of studies to identify disparities in quality of life (QOL), symptoms, and symptom burden between men and women diagnosed with hematologic malignancies., Sample & Setting: 11 studies comprising 13,546 participants aged 18 years or older were included in the analysis. Studies were original peer-reviewed research published in English between January 2005 and December 2020., Methods & Variables: A literature search was performed using keywords associated with health-related QOL, hematologic malignancy, and sex/gender differences. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to identify relevant studies. Data were extracted for sex differences in QOL, symptoms, and symptom burden. All studies were appraised for quality and level of evidence., Results: Women have worse physical health and function, more pain, and higher symptom burden compared with men., Implications for Nursing: Healthcare providers need to understand the impact of sex-based differences on QOL, symptoms, and symptom burden to provide optimal, personalized care.

Cardiovascular (CV) risk mitigation is an important consideration in the management of chronic myeloid leukemia (CML) patients. Although BCR-ABL1 inhibition by tyrosine kinase inhibitors (TKI) has led to a significant improvement in prognosis, the majority of CML patients will require indefinite TKI therapy. Given the success of therapy, there has been a shift in focus to include CV care as part of routine patient management. To optimize outcomes, both patient-specific comorbidities and a detailed understanding of the cardiotoxicity safety profiles imparted by each TKI should be considered during agent selection. Clinicians face the challenge of early detection and management of these cardiotoxicities while balancing the risk-benefit ratios of maintaining life-saving cancer therapy. Advanced practitioners play a critical role in CML patient management that extends to the recognition and management of TKI-associated side effects. They should be cognizant of the potential for TKI-associated cardiotoxicities along with appropriate baseline risk assessments, active surveillance, and mitigation strategies as part of a collaborative team effort with cardio-oncologists., Competing Interests: Dr. Nodzon has served as a consultant for Takeda, AbbVie, and Genentech, and as a speaker for AbbVie and Genentech.

Ponatinib is associated with cardiovascular adverse events (CAEs), and its frequency in the real world is limited. In this retrospective study, we examined the survival outcomes and associated toxicities in 78 consecutive ponatinib-treated patients with chronic myeloid leukemia (CML) at the Moffitt Cancer Center from January 2011 through December 2017. The most common non-CAE was thrombocytopenia (39.7%), occurring in a dose-dependent fashion. Eighteen patients (23.1%) experienced some form of CAE, with the most common being arrhythmia (9%) and hypertension (7.7%), whereas 3 patients experienced myocardial infarction (3.8%). Before 2014, most patients were started on ponatinib 45 mg daily. There was an inverse correlation between cardio-oncology referral and the number of CAEs (P = .0440); however, a lower ponatinib starting dose, more frequent dose reduction, and increased cardio-oncology referral all were likely to have contributed to the observed decrease in CAEs after 2014. The response rate and 5-year overall survival (OS) were higher than those observed in the Ponatinib Ph+ ALL and CML Evaluation (PACE) trial (major molecular response, 58.7% vs 40% and OS, 76% vs 73%; median follow-up of 32.5 months). Ponatinib-treated patients with chronic phase-CML did not show a significant improvement with allogeneic stem cell transplantation, whereas those with accelerated phase/blast phase-CML had a much better outcome (median OS of 32.9 months vs 9.2 months; P = .01). These results demonstrate that ponatinib is highly effective. Dose adjustments and increased awareness of the cardiotoxicities associated with ponatinib may help maximize its benefits., (© 2020 by The American Society of Hematology.)

Purpose: Preclinical evidence indicates that the bone marrow microenvironment provides a protective niche for leukemic stem cells, allowing them to evade the effects of BCR-ABL tyrosine kinase inhibitors (TKIs), but that targeting of the JAK-STAT pathway with the JAK2 inhibitor ruxolitinib increases TKI-induced apoptosis. A phase I clinical trial (NCT01702064) investigated the tolerability and safety of treating chronic-phase chronic myeloid leukemia patients with ruxolitinib in combination with the BCR-ABL TKI nilotinib and explored initial efficacy evidence., Experimental Design: Eleven patients already treated with single-agent nilotinib (300-400 mg twice daily) commenced combination therapy, and molecular responses were evaluated after 6 months. Three ruxolitinib dose cohorts were studied: 5 mg, 10 mg, and 15 mg twice daily., Results: One patient experienced a grade 3/4 adverse event (hypophosphatemia) and 36% of patients experienced grade 1/2 anemia. Of 10 patients who were evaluable for responses, 40% had undetectable BCR-ABL transcripts, as measured by quantitative RT-PCR after 6 months. Plasma inhibitory assay results revealed a decrease in phospho-STAT3 levels after treatment with ruxolitinib. The recommended phase 2 dose of ruxolitinib was 15 mg BID., Conclusions: Overall, this combination was safe and well-tolerated, and the molecular responses were encouraging, thereby warranting further investigation in a phase 2 trial., (Copyright © 2018 Elsevier Ltd.

Immunoglobulin heavy-chain variable region (IGHV) mutational status and karyotype abnormalities are important prognostic factors in chronic lymphocytic leukemia (CLL). The goal was to assess the impact of IGHV in CLL patients with isolated favorable genetic aberrations (del13q, trisomy 12, or negative fluorescence in situ hybridization [FISH]). We studied 273 CLL patients with both IGHV mutational status and cytogenetic information: 145 with isolated del13q 49 with sole trisomy 12 and 79 with negative FISH. After a median follow-up of 7.8 years, patients with del13q-unmutated IGHV had a shorter time to first treatment (TFT) (2.98 vs. 17.44 years; p < .001) and shorter overall survival (10.45 years vs. not reached; p = .0026). Patients with negative FISH-unmutated IGHV had shorter TFT (p = .02) (3.10 vs. 9.75 years, p = .053). IGHV status did not influence clinical outcomes in trisomy 12 CLL. In conclusion, IGHV mutational status shows prognostic impact in CLL patients with good prognosis genomic features.

Chronic lymphocytic leukemia (CLL) is an incurable disease in need of new therapeutic strategies. The immunomodulatory agent, lenalidomide, has shown activity as salvage therapy for CLL. In this phase II trial, we combined lenalidomide with rituximab in 25 patients (range, 41-79) with refractory/relapsed CLL. Lenalidomide was administered orally on escalating doses, with cycle 1 doses of 2.5mg daily on days 1-7, 5mg on days 8-14, and 10mg on days 15-21 followed by 7days off. On cycle 2 and beyond, lenalidomide was administered at 20mg daily on days 1-21. Rituximab was administered at 375mg/m(2) intravenously on a weekly basis for the first cycle starting on day 15 for 4 doses, with each cycle being 28days. Treatment was continued until disease progression or toxicity. Overall response rate was 45.8% on intent-to-treat and 61.1% in evaluable patients (all partial responses). Median time to treatment failure was 14.3 months for evaluable patients, and median overall survival was not reached. The most common grade 3/4 toxicity was neutropenia (72% of patients). The most common nonhematologic toxicity was infection (29% of patients). Lenalidomide combined with rituximab showed activity in heavily treated refractory CLL with an acceptable toxicity profile., (Copyright © 2016 Elsevier Ltd. All rights reserved.)
