ABSTRACT

PURPOSE OF REVIEW: Cancer and cardiovascular disease are among the leading causes of morbidity and mortality in the USA. Cancer and cardiovascular disease have inflammatory underpinnings that have been associated with both the development and progression of these disease states.

RECENT FINDINGS: Inflammatory signaling has been found to be a critical event in both cardiovascular disease and cancer formation and progression. Further, many chemotherapeutic agents potentiate inflammation exacerbating existing cardiovascular disease or leading to its presence. The exact mechanisms of these interactions remain poorly understood. The proinflammatory milieu observed in both cancer and cardiovascular disease likely plays an important role in the development and potentiation of both conditions. Further evaluation of this relationship will be critical in the development of new diagnostic and therapeutic modalities.

Characterization of functioning in breast cancer survivors: an interpretive descriptive analysis study based on the International Classification of Functioning, Disability, and Health (ICF) and the Item-Perspective Classification Framework

Disabil Rehabil. 2023 May 26:1-19. doi: 10.1080/09638288.2023.2212915. Online ahead of print.

ABSTRACT

PURPOSE: Breast cancer survivors may experience a variety of disabilities that could potentially compromise their independent functioning. This study aimed to examine their perspectives and experts on their functioning and interpret concepts with the International Classification of Functioning, Disability, and Health (ICF) and the Item-Perspective Classification Framework (IPF).

METHODS: Interpretive descriptive methods were used with in-depth interviewing with 16 breast cancer survivors and 22 experts using a semi-structured interview guide. The interviews were recorded, transcribed, and qualitatively analyzed using thematic analysis. The extracted data were linked to the ICF Core Set for Breast cancer and were interpreted by the IPF.

RESULTS: Four main themes emerged to define the functioning of breast cancer survivors: body functioning, physical functioning, social functioning, and mental functioning. Three other factors were also categorized as modifiers of functioning personal, emotional, and environmental. The 592 extracted meaningful concepts were linked to 38 (47%) categories from the ICF: 16 Body Functions, 14 Activities and Participation, and 8 Environmental Factors. The IPF classified all the extracted concepts, and most rational appraisals fell in the biological (B) domain. The concepts that required emotional appraisal were classified in Psychology (P).

CONCLUSION: Psychological and emotional factors were pivotal in defining functioning in patients with BC.

Association between RCT methodology and disease indication with mineralocorticoid-related toxicity for patients receiving abiraterone acetate for advanced prostate cancer: A meta-analysis of RCTs

Clin Genitourin Cancer. 2023 Apr 23:S1558-7673(23)00093-9. doi: 10.1016/j.clgc.2023.04.007. Online ahead of print.

ABSTRACT

INTRODUCTION: While abiraterone acetate (AA) has demonstrated survival benefit in advanced prostate cancer (APC), meaningful cardiotoxicity is observed. It is unclear whether the magnitude differs based on disease indication and concurrent steroid administration.

METHODS: We performed a systematic review and meta-analysis of phase II/III RCTs of AA in APC published as of August 11, 2020. Primary outcomes examined were all- and high-grade (grade ≥ 3) hypokalemia and fluid retention, and secondary outcomes included hypertension and cardiac events. We performed random effects meta-analysis comparing intervention (AA + steroid) and control (placebo ± steroid), stratified by treatment indication and whether patients received steroids.

RESULTS: Among 2,739 abstracts, we included 6 relevant studies encompassing 5901 patients. Hypokalemia and fluid retention were observed more frequently among patients receiving AA (odds ratio [OR] 3.10 [95% CI 1.69-5.67] and 1.41 [95% CI 1.19-1.66]). This was modified by whether patients in the control received steroids: trials where control patients did not demonstrated a larger association between AA and hypokalemia (OR 6.88 [95% CI 1.48-2.36] versus OR 1.86 [95% CI 4.97-9.54], P < .0001) and hypertension (OR 2.53 [95% CI 1.91-3.36] vs. OR 1.55 [95% CI 1.17-2.04], P = .1) than those where steroids were administered. We observed heterogeneity due to indication: there were greater effects on hypokalemia (P < 0001), hypertension (P = .03), and cardiac disorders (P = .01) among patients treated for mHSPC than mCRPC.

CONCLUSIONS: The magnitude of cardiotoxicity with AA differs based on trial design and disease indication. These data are valuable in treatment decisions and highlight utilization of appropriate data for counseling.
