Brief Summary

Open and multicenter randomized clinical trial (1:1) comparing limited screening with extended screening with the performance of Positron emission tomography-computed tomography (PET-CT) scan in the search for neoplasms in patients with unprovoked venous thromboembolic disease at high risk of developing cancer at follow-up. Introduction: Cancer screening in patients with unprovoked venous thromboembolic disease (VTE) is controversial. In the last years, a score has been developed that selects patients at high risk of developing cancer during follow-up. Objective: To estimate the impact of an active cancer search strategy using 18-fluordesoxiglucose (FDG) PET-CT in unprovoked VTE with high-risk to develop cancer. Specific Objectives: 1) Number of neoplasms diagnosed in the screening process: 2) number of neoplasms diagnosed at an early stage, 3) impact on survival of the strategy; and 4) impact on the quality of life. Cancer will be considered from 30 days up to 12 months after the diagnosis of VTE. Scope: 20 Spanish hospitals. Design: Open-label, multicentre Randomized clinical trial (1: 1) comparing the performance of PET-CT versus limited screening for cancer. Population: Patients older than 18 years with unprovoked VTE at high risk of presenting cancer at follow-up (≥3 points in the score of Jara-Palomares et al., Chest 2017). Follow-up: 12 months after VTE. Sample: The sample size calculated is 650 patients, to obtain a power of 80%, with a level of significance of 5%, and taking into account a 10% loss of follow-up.

Outcome Measures

Primary Outcomes (1)

  • Number of neoplasms diagnosed using extended screening

    Estimate the impact of an active cancer search strategy using PET-CT in the number of neoplasms diagnosed in the screening process in patients with high-risk unprovoked thromboembolic disease.

    After 3 years of follow-up

Secondary Outcomes (3)

  • Number of neoplasms diagnosed in early phase using extended screening

    After 3 years of follow-up

  • Overall survival of patients with high-risk unprovoked thromboembolic disease performing limited/extended screening

    Until the patient death or finalization of study after three years of follow-up

  • European Quality of Life-5 (EQ-5D scale validated in Spanish) of patients with high-risk unprovoked thromboembolic disease performing limited/extended screening

    Baseline and after 90, 180 and 365 days of follow-up

Study Arms (2)

Limited screening

NO INTERVENTION

Complete clinical history, along with routine physical, analytical examination (creatinine, sodium, potassium, red series, white series, liver and calcium profile) and chest x-ray.

Extended screening

EXPERIMENTAL

Limited screening plus positron emission tomography / computed tomography with 18 FDG (18FDG PET-CT).

Drug: Fludeoxyglucose 18F

Interventions

The performance of the 18 FDG PET-CT will require fasting of at least 6 hours, and the glycemia will have to be lower than 126 mg / dL before the injection of 3-5 MBq / kg of 18FDG. Intravenous injection will follow a period of approximately 60 minutes in a quiet room. Computed tomography (CT) will be performed from the middle of the forehead to the feet with normal and shallow breathing using a low dose adjustment Iodinated contrast will not be administered intravenously.

Also known as: 18-Fludeoxyglucose (18FDG)
Extended screening
