Prospective Evaluation of the Treatment of Cancer Associated Superficial Venous

Superficial venous thrombosis (SVT) is very common in clinical practice. What's more, around 15- 20% of SVTs occur in the context of cancer. Today, cancer patients are excluded from therapeutic trials for DVT. There is therefore no high-level evidence-based treatment recommendation for these patients. Recent data suggest that the course of cancer-associated DVT is similar to that of cancer-associated deep vein thrombosis (DVT). However, there are currently few prospective data on the evolution of cancer-associated DVT in relation to the treatment used. Due to the absence of clear recommendations of treatment in case of SVT associated with cancer the investigators will perform a prospective observational study to evaluate the efficacy of different regiment of anticoagulant treatment ordered in clinical practice.

A Pilot Trial Comparing Full Dose Rivaroxaban to Prophylactic Dose Rivaroxaban in Patients With Superficial Vein Thrombosis in the Leg

The goal of this clinical trial, called a pilot study or a feasibility study, is to test the study plan and to find out whether enough participants will join a larger study and accept the study procedures. This type of study includes a small number of participants so it is not expected to prove how safe the treatment is or how well the treatment works. The main question it hopes to answer is: 1.What is the average number of patients that are recruited per month during the 12 month study period? To test the study plan, adults being treated for a superficial vein thrombosis (SVT), which is a blood clot in the superficial veins of the leg, will be given a type of blood thinner called rivaroxaban. Half of the participants in this study will be given the standard (low-dose) rivaroxaban for 45 days, then 45 days of placebo (a substance that looks like the study medication but does not have any active or medicinal ingredients). The other half of participants will be given full-dose rivaroxaban for a total of 90 days. The placebo in this study is not intended to have any effect on the participants blood clot. A placebo is used to make the results of the study more reliable.
