What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
Prior to gender affirming surgery, do you hold estrogen (or convert to transdermal) to minimize postoperative VTE risk?
I'd divide this into 2 sub-questions: what to do in a patient who has a history of thrombosis, and what to do in a patient without a history of thrombosis. In a patient with prior thrombosis, I would generally have them on indefinite anticoagulation alongside ongoing estrogen use. We know that trans...
How would you approach anticoagulation for a patient with acute bilateral pulmonary emboli related to malignancy, but with a concomitant cavitary lung mass experiencing episodic, small-volume hemoptysis?
This is an interesting question to which we need to apply the art of medicine, weighing the risks and benefits of treatment. The major fatal events in this exact scenario are: Recurrent PE from undertreatment. Sudden massive hemoptysis after aggressive anticoagulation. The physician's management s...
When would you use AVD + brentuximab instead of ABVD for newly diagnosed stage 3 or 4 Hodgkin lymphoma?
By reducing the risk of primary treatment failure from 23% to 18%, the ECHELON-1 study demonstrated that compared to ABVD, AVD + brentuximab vedotin reduces the risk of primary treatment failure by about 25% for patients with advanced-stage classic Hodgkin lymphoma. If given with prophylactic G-CSF,...
How do you decide between anticoagulation and observation for an incidentally detected subsegmental pulmonary embolism in elderly patients with a history of gastrointestinal bleeding?
We face this conundrum not infrequently because subsegmental emboli are subject to high inter-reader variability, and the accuracy of the finding in isolation is suspect (Batayneh et al., Blood 2023). I once mentioned this to a radiologist who reads CTAs and was told, tactfully, that I was full of i...
Would you consider restarting IMID therapy in a patient with recent stroke while on IMID?
This is a very good question, and practice likely differs across institutions as data is limited. The discussion below refers primarily to the immunomodulatory (IMID) agents lenalidomide and pomalidomide.As you are aware, IMID therapy is known to be associated with an increased risk for venous throm...
How do you approach ADT in patients with high-risk prostate cancer who have risk factors for VTE, such as Factor V Leiden?
My default recommendation for patients with localized, high-risk prostate cancer is to recommend the use of long-term ADT. This intervention seems to offer a relatively large, clinically significant OS benefit for patients in the modern era receiving dose-escalated ADT. This benefit has been observe...
How do you counsel patients on the risk of thromboembolic complications with use of immunotherapy in NSCLC?
Patients with metastatic lung cancer are at increased risk of thromboembolic events with an estimated frequency of 13.9% (Connolly et al., PMID 23026639). Preclinical data show that PD-1/PD-1 pathway blockade may lead to increased levels of pro-inflammatory cytokines and T cell driven progression an...
Do you utilize D-dimer to inform anticoagulation duration in the treatment of VTE?
I had developed a policy during my last eight or ten years of practice evaluating how long patients should be treated after a thrombosis and I'd like to share some impressions over these years as well as conclusions that I reached. These conclusions formed the basis of my approach to this problem. I...
What are your top takeaways in Hematologic Malignancies from ASH 2025?
The PARADIGM study is a very important one that may result in a paradigm change for the treatment of AML. The study showed that outcomes are equal or better with AZA + VEN among patients with AML suitable for intensive chemotherapy. The efficacy was superior in response rate and EFS (but not overall...
