Impact of cancer history on clinical outcome in patients undergoing transcatheter edge-to-edge mitral repair.


ABSTRACT:

Background

Little is known about the prevalence of a history of cancer and its impact on clinical outcome in mitral regurgitation (MR) patients undergoing transcatheter mitral valve repair (TMVR).

Objectives

The purpose of this study is to investigate the prevalence of cancer, baseline inflammatory parameters, and clinical outcome in MR patients undergoing TMVR.

Methods

Consecutive patients undergoing a MitraClip procedure were enrolled, and the patients were stratified into two groups: cancer and non-cancer. Baseline complete blood counts (CBC) with differential hemograms were collected prior to the procedure to calculate the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR). All-cause death within a one-year was examined.

Results

In total, 82 out of 446 patients (18.4%) had a history of cancer. Cancer patients had a significantly higher baseline PLR [181.4 (121.1-263.9) vs. 155.4 (109.4-210.4); P?=?0.012] and NLR [5.4 (3.5-8.3) vs. 4.0 (2.9-6.1); P?=?0.002] than non-cancer patients. A Kaplan-Meier analysis revealed that cancer patients had a significantly worse prognosis than non-cancer (estimated 1-year mortality, 20.2 vs. 9.2%; log-rank P?=?0.009), and multivariable analyses of three models showed that cancer history was an independent factor for 1-year mortality. Patients who died during follow-up had a significantly higher baseline PLR [214.2 (124.2-296.7) vs. 156.3 (110.2-212.1); P?=?0.007] and NLR [6.4 (4.2-12.5) vs. 4.0 (2.9-6.2); P?ConclusionsIn MitraClip patients, a history of cancer was associated with higher inflammatory parameters and worse prognosis compared to non-cancer patients.
