How do cancer patients feel about different types of anticoagulants for blood clots?

THIS MONTH’S EDITOR’S CHOICE FROM PALLIATIVE MEDICINE …

Ann Hutchinson and Miriam Johnson from the Hull York Medical School, University of Hull, England, explain the background to their longer article selected as ‘Editor’s choice’ in the May 2019 issue of Palliative Medicine.

Clinicians are rightly concerned that the burden of long-term injectable anticoagulation in people with cancer and thrombosis is significant. We therefore interviewed 37 people with cancer-associated thrombosis about their experiences of taking anticoagulants in the form of injections and/or tablets. The patients interviewed were taking part in the select-d trial (investigating the relative efficacy and safety of rivaroxaban [tablet] and dalteparin [injection]) run by the University of Warwick.

Patients told us that they found tablets convenient but that they found injections were acceptable in the context of having cancer, especially if they were supported to overcome their initial worries about self-injection. Despite drawbacks such as scarring and bruising around the injection site, they said the injections were a small price to pay to treat the life-threatening blood clots.

“You’re just feeling that you’re actually doing something, it’s a step forward. It’s contributing, me stomach’s not good at this moment, but if I keep injecting me leg’s going down, I can see, look, it’s turning back to what it were.”P4

Although patients find taking tablets easier, many would only choose tablets over injections only if they were as safe and effective as the injections.

“If a tablet would serve the same purpose then I would certainly sooner take a tablet, but … if the injections are an advantage then it’s worth putting up with the discomfort. “P11

An additional finding, confirming other reports  and a recent European survey of over a thousand people with cancer, was that although cancer patients have a four- to five-fold greater risk of getting blood clots than the general population, most of our study participants did not know that they were at increased risk. Importantly, neither did they know the signs and symptoms for which they should seek medical help; hence they delayed seeking life-saving treatment.

“I’d been in pain with my leg for a good week or so, but you just think it’s part of the cancer.” P2

Blood clot

Based on what patients told us we recommend that:

  • Clinicians take both clinical guidelines and patient preference into account when deciding what treatment to offer for blood clots, without undue worry that injections may be too burdensome for patients.
  • All patients should be informed soon after their cancer diagnosis of their increased risk of blood clots and the danger signs and symptoms.

We are working with Thrombosis UK and Anticoagulation UK to disseminate these findings and to raise awareness amongst cancer patients of their risk of thrombosis.

If you are working with cancer patients, please let them know the signs and symptoms that should trigger seeking medical help quickly; they should not assume these are due to the cancer or other medical conditions.
