Purpose: Venetoclax is the standard of care for chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) but requires intensive monitoring for optimal safety. Clinical relevance of intensive monitoring in practice is unknown, especially for patients with low or intermediate risk for tumor lysis syndrome (TLS).

Patients and methods: A retrospective review was conducted to determine clinical significance of monitoring for TLS during standard ramp-up for patients with CLL/SLL. Patients receiving abbreviated ramp-up, clinical trials, or concurrent Bruton tyrosine kinase inhibitors were excluded. The primary end point was TLS incidence, with secondary end points describing associated clinical interventions.

Results: Fifty-five patients met study criteria. The majority of patients received venetoclax as first-line therapy (58%), with anti-CD20 antibody therapy (82%), and were at low risk of TLS (75%). No clinical TLS events occurred, whereas laboratory TLS occurred in only 1.8% of patients. No patients required antihyperuricemic therapy, and few interventions for hyperphosphatemia or hypocalcemia (3.6% of patients) were required. Additional intravenous fluids were uncommonly required (1.8% of patients), and no unplanned hospitalizations were required.

Conclusion: These findings support efforts to reduce intensive monitoring requirements during venetoclax ramp-up for patients with CLL, potentially increasing accessibility of venetoclax.

Purpose: Venetoclax has made a significant impact in the treatment of chronic lymphocytic leukemia (CLL) due to its ability to induce deep and durable remissions with a finite duration of oral therapy. However, it can lead to tumor lysis syndrome (TLS) which is mitigated with dose escalation strategies. Patients who initiate venetoclax need to follow rigorous, and potentially burdensome, TLS monitoring during dose ramp-up. The frequency with which this rigorous monitoring leads to therapeutic interventions in clinical practice has not been well described. We conducted a study to assess the incidence of TLS and interventions needed after initiation of venetoclax in patients with CLL.

Methods: Adult patients with CLL who started treatment with venetoclax between July 2017 and March 2021 at Levine Cancer Institute were included in this study. Adherence to the venetoclax package insert (PI) for tumor lysis monitoring, incidence of laboratory as well as clinical TLS, and interventions resulting from the monitoring of TLS were collected.

Results: We report outcomes on 73 consecutive patients with CLL who initiated venetoclax. The majority of patients had low (49%) or medium (44%) tumor burden. During venetoclax ramp-up, 66% of patients adhered strictly to TLS monitoring as per the venetoclax PI. One patient developed laboratory TLS, and no patients developed clinical TLS. Six patients received unplanned interventions to treat TLS; all had medium or high tumor burden. There were no unplanned interventions in patients with low tumor burden.

Conclusion: In patients with low and medium tumor burden CLL who start venetoclax, the incidence of TLS is very low, and interventions are uncommonly needed.

Purpose: In 2017, the National Cancer Institute (NCI) funded the Cancer Center Cessation Initiative (C3I) to implement and expand tobacco treatment programs in routine oncology care. Many C3I programs developed specialty care programs staffed by tobacco treatment specialists (TTSs) to deliver evidence-based treatment to adult patients who smoke. People involved in specialty tobacco treatment programs can help to identify implementation strategies and adaptations that may enhance tobacco treatment reach and effectiveness in cancer care and help more patients with cancer quit using tobacco.

Methods: We conducted semistructured interviews with TTSs from 21 C3I-funded cancer centers and applied content analysis to interview transcripts from 37 TTSs and 17 respondents in other program roles. We used the Consolidated Framework for Implementation Research to code interview data. We identified final themes and implementation strategies and adaptations recommended by respondents on the basis of these codes.

Results: Respondents shared that implementation of specialty tobacco treatment programs in cancer care settings could be facilitated by training staff to provide patient connection to services, incorporating prescription of no- or low-cost cessation medications, hiring additional staff to deliver tobacco treatment, allocating space to the program, and automating electronic health record workflows.

Conclusion: TTSs and others involved in specialty tobacco treatment in NCI-designated cancer centers identified ways to improve tobacco treatment access, use, and effectiveness by (1) adapting specialty tobacco treatment delivery to meet patient needs; (2) facilitating referrals and pharmacotherapy coordination; and (3) committing staffing, space, and support resources to tobacco treatment programs. Key program participants suggested that these approaches would help more oncology patients connect with evidence-based tobacco treatment and quit smoking.

Purpose: Ovarian function suppression (OFS) with gonadotropin-releasing hormone agonists (GnRHas) is a standard of care for premenopausal patients with high-risk stage II/III hormone receptor-positive breast cancer (BC). Practical guidance on the optimal choice of GnRHa, timing, schedule, and monitoring is limited. Our aim was to determine how oncologists use OFS in routine care.

Methods: We designed a questionnaire to determine the choice of GnRHa, schedule, duration, initiation, use of bone modifiers, and monitoring of estradiol (E2). The questionnaire was sent to oncologists treating BC, in practice for >1 year and participating in the ASCO Research Survey Pool (RSP). It was also forwarded by investigators to oncologists meeting these criteria. The survey was open between November 14, 2023, and January 5, 2024.

Results: Of 996 oncologists participating in the ASCO RSP, 178 (18%) completed the survey. An additional 56 oncologists contacted by investigators responded. Respondents were from the United States (57%), Asia (15%), and Europe (14%). Goserelin (54%) and leuprolide (39%) were the most frequently used GnRHas and were administered once every month by 46%. Approaches to starting GnRHas were varied. Most continued them for the duration of aromatase inhibitor therapy (57%). Estradiol monitoring was performed regularly, sometimes, or never by 43%, 27%, and 27%, respectively. The E2 assays used were standard (65%), ultrasensitive (16%), and unknown (14%). Interpreting E2 assay results were considered difficult by 55%; however, 62% of oncologists changed treatment on the basis of them. A total of 92% of respondents would like ASCO guidance on the practical use of OFS.

Conclusion: Considerable practice variation exists for similar clinical scenarios in OFS administration. Respondents would welcome ASCO guidance on all aspects of OFS.

Purpose: Limited health literacy-ability to obtain, process, and understand health information-can hinder communication, access to medical treatment, and identification and management of comorbidities. Older adults have high rates of poor health literacy, but its role in aging-related outcomes among older adults with cancer is understudied.

Methods: We included 876 older adults age 60 years and older with cancer from the Cancer and Aging Resilience Evaluation Registry completing self-reported geriatric assessment, including health literacy, at first visit to medical oncology. The exposure was limited health literacy. Outcomes were frailty, physical/mental health-related quality of life (HRQOL), and health care utilization. We used modified Poisson regression to examine the association of exposure on outcomes adjusting for age, race-ethnicity, sex, and cancer type/stage.

Results: Median age at enrollment was 68; 57.8% were male; 20.2% were non-Hispanic Black. The most prevalent cancers were advanced-stage (46.8% stage IV) colorectal (26.9%) and pancreatic (19.0%). Those with limited health literacy were older (70 v 68 years; P < .001), male (63.0% v 55.1%; P = .026), non-Hispanic Black (28.8% v 16.1%; P < .001), ≤high school educated (62.3% v 28.1%; P < .001), and retired/disabled (86.3% v 71.2%; P < .001). In multivariable analysis, limited health literacy was associated with higher prevalence of frailty (prevalence ratio [PR], 2.64 [95% CI, 2.15 to 3.26]), impaired physical (PR, 1.90 [95% CI, 1.59 to 2.27]) and mental (PR, 2.08 [95% CI, 1.76 to 2.47]) HRQOL, and hospitalization in the last year (PR, 1.28 [95% CI, 1.10 to 1.48]) versus adequate health literacy.

Conclusion: Older adults with cancer and limited health literacy had higher adjusted prevalence of frailty, impaired physical and mental HRQOL, and recent hospitalization. Interventions to address limited health literacy should be explored in this vulnerable and growing cancer population.

Molecular prognostic and diagnostic tools allow for targeted cancer surveillance, prognostication, and treatment, and these assays have the potential to improve the lives of patients and their relatives. The impact of these advances, however, is not uniform across populations. Underserved communities frequently do not have the same level of access to novel assays, and the clinical application of these tools is often limited by disproportionate representation of White and European ancestry populations in foundational data, as well as limited diversity in clinical trials. In this review, we highlight major advances in clinical molecular assays, key areas of disparity, and contributing factors. We then list ongoing and future areas of intervention to improve access to and efficacy of molecular assays across populations, so that we as a community may work to improve equity at this critical area of cancer care.
