Relapsed chronic lymphocytic leukemia with a cardiac mass: A case report.

Chronic lymphocytic leukemia (CLL) is the most common hematological malignancy in the USA. Extra-medullary disease is very rare and is not well characterized. In practice, clinically significant cardiac or pericardial involvement by CLL is extremely rare with only a few case reports in literature. We report a 51-year-old male patient with a past medical history of CLL in remission, who presented with fatigue, dyspnea on exertion, night sweats and left supraclavicular lymphadenopathy. Laboratory investigations were notable for leukopenia and thrombocytopenia. Due to high suspicion of an underlying malignant process, a full body computerized tomography (CT) scan was obtained and showed an 8.8 cm soft tissue mass-like lesion occupying the majority of the right atrium and extending into the right ventricle, with probable pericardial involvement. Enlarged left supraclavicular and mediastinal lymph nodes were also present and had a mild mass effect on the traversing left internal thoracic artery and left pulmonary artery. A transesophageal echocardiogram and cardiac magnetic resonance imaging (MRI) were done to better characterize the cardiac mass. They confirmed a large infiltrating mass (measuring 10 × 7.4 cm) in the right atrium and ventricle, extending into the inferior vena cava inferiorly and coronary sinus posteriorly. A left supraclavicular excisional lymph node biopsy was performed and histopathology was consistent with Small Lymphocytic Lymphoma (SLL)/CLL. This case represents one of the few known cases of cardiac extramedullary-CLL presenting with an isolated cardiac mass. Further studies are needed to characterize the course of the disease, prognosis and optimum management along with the role of surgery.

Economic Evaluation of a Geriatric Oncology Clinic.

Geriatric assessment (GA) is supported by recent trials and guidelines yet rarely implemented due to a lack of resources. We performed an economic evaluation of a geriatric oncology clinic. Pre-GA proposed treatments and post-GA actual treatments were obtained from a detailed chart review of patients seen at a single academic centre. GA-based costs for investigations and referrals were calculated. Unit costs were obtained for surgical, radiation, systemic therapy, laboratory, imaging, physician, nursing, and allied health care (all in 2019 Canadian dollars). A six-month time horizon and government payer perspective were used. Consecutive patients aged 65 years or older (n = 152, mean age 82 y) and referred in the pre-treatment setting between July 2016 and June 2018 were included. Treatment plans were modified for 51% of patients. Costs associated with planned treatment were CAD 3,655,015. Costs associated with GA and related interventions were CAD 95,798. Final treatment costs were CAD 2,436,379. Net savings associated with the clinic were CAD 1,122,837, or CAD 7387 per patient seen. Findings were robust in multiple sensitivity analyses. Combined with mounting trial data demonstrating the clinical benefits of GA, our data can inform a strong business case for geriatric oncology clinics in health care environments similar to ours, but additional studies in diverse health care settings are warranted.

Delirium incidence, risk factors, and treatments in older adults receiving chemotherapy: A systematic review and meta-analysis.

INTRODUCTION: Older adults with cancer are at increased risk of delirium due to age, comorbidities, medications, cognitive impairment, and possibly cancer treatments. However, there is scant information on the risks of delirium with chemotherapy and approaches to prevent or treat it. We performed a systematic review and meta-analysis to summarize available evidence. MATERIALS AND METHODS: We systematically searched peer-reviewed journal articles in English, French, German, and Dutch from five databases from 1990 to May 2019 to identify studies examining delirium in adult patients receiving chemotherapy. We also attempted to identify delirium risk prediction models and prevention or treatment trials. All reviews and data extraction were performed by two independent reviewers. Summary estimates were derived from random effects models. RESULTS: A total of 23,389 titles and abstracts were screened, and 1272 full-text articles were reviewed. Nineteen articles reported on delirium using an acceptable diagnostic standard. Sample sizes varied from 7 to 324. The incidence of delirium ranged from 0 to 51% (weighted mean 9%, 95% confidence interval 5-16%). In a sensitivity analysis including 122 studies that used terminology suggestive of delirium but did not meet our inclusion criteria, the weighted incidence of delirium was 10% (95% confidence interval 8-12%). Age was not consistently associated with increased delirium risk. No intervention studies to prevent or treat delirium were identified. CONCLUSIONS: Delirium may occur in 1 in 11 older adults receiving chemotherapy; however, there were substantial limitations in reported studies. This systemic review highlights key gaps in knowledge, particularly regarding risk factors, prevention, and treatments.

Downstream consequences of abnormal cognitive screening in older adults seen pretreatment in a geriatric oncology clinic.

INTRODUCTION: Although screening for cognitive impairment (CI) is an important part of a comprehensive geriatric assessment (CGA), little is known about the downstream work-up of abnormal screening or its impact on cancer treatment. We characterized the downstream workup in diagnosing CI and its impact on cancer treatment decision-making. METHODS: Patients who underwent a pre-treatment CGA at an academic Geriatric Oncology (GO) clinic between July 2015 and June 2018 and had a positive Mini-Cog (≤ 3 out of 5) screen were included. Data were collected from medical charts and database review. Analyses were primarily descriptive. RESULTS: Of 82 patients seen in the pre-treatment setting, 46 (56.1%) had a positive Mini-Cog screen. Of those, 12 (26.1%) were diagnosed with dementia, 8 (17.4%) were diagnosed with mild cognitive impairment and 10 (21.7%) had CI not otherwise specified. Although 46 patients had a positive screen, only 30 patients (65.2%) were classified as cognitively "abnormal" in the GO team final assessment. Change to oncologic treatment due to CI was seen in 12 (40.0%) cases. Increased delirium risk was identified in 9 (75.0%) of 12 surgical cases; however, delirium prevention was only recommended in 5 cases (55.6%). Strategies to optimize patients with CI included targeting falls prevention (n = 13), home/personal safety (n = 7), medication safety (n = 7), and nutrition (n = 6). Pharmacotherapy for cognition was not recommended in any case. CONCLUSION: Undiagnosed CI is prevalent in the GO setting and influenced treatment in 40.0% of cases. Gaps were identified in clinician and patient/caregiver education around delirium risk. Addressing these issues may improve patient care.
