NCT ID: NCT04042298 Recruiting - Breast Cancer Clinical Trials

Microvascular Function in Patients Undergoing 5-Fluorouracil Chemotherapy

Start date: June 25, 2019
Study type: Observational

The primary aim of this study is to investigate potential differences in vascular function between patients receiving 5-Fluorouracil (5-FU) chemotherapy, patients receiving chemotherapies other than 5-FU, cancer survivors who were treated with 5-FU, and an age and sex matched control. 5-FU is the third most commonly administered chemotherapeutic agent and its use is associated with the second most occurrences of cardiotoxicity. Despite the known cardiotoxic effects of 5-FU, it's effects on the human vasculature are not well understood. To achieve the goals of this project Laser Doppler flowmetry (LDF) will be used to assess blood flow within the skin microcirculation of the forearm in cancer patients who have received 5-Fluoruracil within the past 30 days (Experimental Group), cancer patients receiving radiotherapy and/or chemotherapy other than 5-Fluorouracil, and an age and sex matched control (Control Group). LDF utilizes a small (~3 cm) non-invasive sensor placed on the skin. The sensor shines light into the skin, and upon contact with red blood cells (RBCs), the light is reflected and scattered. This information is used to evaluate microvascular blood flow and has previously been used in clinical populations.

NCT ID: NCT03486340 Recruiting - Clinical trials for Acute Coronary Syndrome

Prevention of Chest Pain in Chemo-treated Cancer Patients

Start date: April 11, 2018
Phase: N/A
Study type: Interventional

This is a prospective, exploratory, randomised clinical trial. Patients with diagnosed cancer that are to be treated with 5-fluorouracil (5-FU) will be randomised into standard oncological treatment or a cardiological assessment prior to the 5-FU treatment. The investigators hypothesize that aggressive management of ischemic risk factors in asymptomatic patients will reduce the number of hospitalisations and investigations for acute coronary syndrome during and after 5-FU treatment and that patients with high coronary artery calcium scores are more likely to experience chest pain during the treatment with 5-FU.
