High Sensitive Troponin I and Extended Range C-Reactive Protein as Markers to Predict Cardiotoxicity in Locally Advanced Breast Cancer with Neoadjuvant CAF (Cyclophoshpamide, Adriamycin/Doxorubicin, 5Fluorouracil) Therapy

The limitation of echocardiography to measure chemotherapy cardiotoxicity at left locally advanced breast cancer with large ulcer is still serious problem. HsTnI and erCRP are biomarkers to detect cardiotoxicity that are cheap, easy to examine and available at Dr.Soetomo Hospital Surabaya. This study was to compare HsTnI, erCRP and echocardiography as cardiotoxicity predictors in locally advanced breast cancer with neoadjuvant CAF therapy. This study used one group pretest and posttest design among 23 locally advanced breast cancer patients. All patients underwent echocardiography, HsTnI, and erCRP examinations before and after 3 times chemotherapy and compared. The average age was 49.78±8.7. Statistically significant decrease in LVEF was found after treatment (67.98%±4.06 and 64.07%±3.53, p=0.000). HsTnI was significantly increased after treatment (0.007 µg/mL±0.004 and 0.043 µg/mL±0.051 p=0.000). erCRP was significantly decreased after treatment (1.043mg/dL±0.913 and 0.573mg/dL±0.444 p=0.044). Decreased LVEF and increased HsTnI was compared by its cardiotoxic cut-off. HsTnI was significantly better and faster to detect cardiotoxicity (0.033±0.051 p=0.002). In conclusion, strong correlation is present in the detection of cardiotoxicity between HsTnI and LVEF. HsTnI is faster than echocardiography, and could be alternative diagnostic to detect early cardiotoxicity.

Chemotherapy with cyclophosphamide, adriamycin, and fluorouracil (CAF) regiment in patients with locally advanced breast cancer have a risk of cardiotoxicity. Cardiotoxicity examination standards using left ventricular ejection fraction (LVEF) by echocardiography are considered insensitive for detection of subclinical ventricular dysfunction. NT-pro BNP and Hs-Troponin I (hs-TnI) as cardiac biomarkers are expected to help detect early cardiotoxicity. This study intended to analyze the correlation between changes of NT-pro BNP and hs-TnI levels with cardiotoxicity in breast cancer after three cycles of chemotherapy.This was a cross-sectional observational study, conducted at the Dr. Soetomo General Hospital Surabaya. The subjects consisted of 23 breast cancer patients who underwent chemotherapy with CAF regiment. NT-proBNP and hs-TnI examination used CLIA methods (Immulite 1000, ADVIA Centaur TnI-Ultra). Cardiotoxicity based on decreased LVEF to more than 10% of the initial LVEF value using echocardiography. Significant increases in NT pro BNP and hs-TnI levels were obtained before and after treatment (p=0.000, p=0.002). A significant decrease in LVEF was obtained before and after treatment (p=0.000), but only 2 patients (8.7%) showed cardiotoxicity. There was no correlation between changes in NT-pro BNP and hs-TnI levels with changes in LVEF before and after chemotherapy (p=0.666 and r=0.095; p=0.254 and r=-0.28). There was no correlation between changes in NT-pro BNP and hs-TnI levels with cardiotoxicity, which was assessed based on LVEF reduction, in locally advanced breast cancer after three-cycles of chemotherapy with CAF regiment.
