Breast cancer patients’ quality of life: Real-world data.

Abstract

e23115 Background: CareAcross is a digital platform dedicated to support, inform and engage with cancer patients. It also collects medical and other data, and generates real world evidence. Methods: In an effort to collect and analyze information from breast cancer patients regarding side effects in relation to their treatments and supplements intake, we contacted 4837 patients in the UK, Germany, France, Spain and Italy. 474 had triple negative breast cancer (TNBC) and the remaining 4363 other breast cancer subtypes (non-TNBC). All data was collected anonymously, with strong privacy and security controls. Results: Different regimens were given either as adjuvant or as systemic treatments. AC treatment was given to 9% of TNBC vs 4% of non-TNBC patients; FEC-T to 20% vs 13%, FEC to 10% vs 8%, taxanes to 37% vs 20% and platinum-based chemotherapy to 12% vs 2%, respectively. Among non-TNBC patients, 12% received Trastuzumab and 53% received hormonal treatment. Eighty four TNBC and 696 non-TNBC patients were asked regarding side effects as well as vitamins and supplements intake. Among them, 76 TNBC patients reported an average of 2.8 side effects (95% CI 1.0-8.0) vs 577 non-TNBC patients reporting an average of 2.8 side effects (95% CI 1.0-13.0); p < 0.92. Similarly, an average of 5.0 vitamins and supplements was reported by 64 TNBC patients (95% CI 10.0-17.0) and an average of 3.8 was reported by 555 non-TNBC patients (95% CI 1.0-29.0); p < 0.023. Toxicity and supplements are tabulated below. Conclusions: The real world evidence obtained through an international analysis shows that TNBC patients receive more toxic treatments due to the aggressive disease, as expected. However, TNBC patients experience similar toxicities with non-TNBC patients, but their consumption of vitamins and supplements is much higher. [Table: see text]
