How would you manage a middle thoracic esophageal squamous cell carcinoma (tumor is 25-30 cm from carina) with a positive supra-clavicular lymph node?
For Proximal/Mid Thoracic ESCA, supraclavicular node is considered a regional node, and therefore part of the AJCC N1-N3 staging system, and should be managed with locoregional treatment, using preoperative or definitive chemoradiation, to 50-50.4 Gy in 2.0/1.8 Gy per fraction. The node could be tre...
What dose/fractionation do you like to use for palliation of bulky LAD from CLL/SLL?
I have treated patients with bulky mass(es) - mostly parotids of recent. Bulky mass(es) -> I like either 400cGy x1 but most use 200cGy x2 (mostly used by me) -> (Electrons for structures like the parotid, but photons for deeper stuff.) For example, when I treated a few parotids glands, they were swo...
What clinical parameters determine when you treat a large HCC lesion with ablative radiation vs Y-90?
Based on 3 negative randomized trials that have compared Y-90 to relatively inactive targeted therapy (Sorafenib), Y-90 has no evidence-based role in the treatment of HCC. In fact, systemic therapies have improved and 3 regimens have shown a survival benefit for locally advanced and metastatic HCC. ...
Does the use of A+AVD versus ABVD affect your decision for consolidation RT for bulky Hodgkin lymphoma?
A+AVD is an acceptable regimen for advanced HL based on results from the ECHELON-1 study (Ansell et al., PMID 35830649) showing an improvement in both PFS (82% vs 75% at 6 years) and OS (94% vs 89%) compared with ABVD. Radiation therapy was not incorporated into this study.In advanced HL, regardless...
For a patient post-prostatectomy with a high PSA (>1), a negative MRI pelvis, and a negative PSMA PET scan, do you pursue any other imaging?
The sensitivity of PSMA scan for PSA above 1 is about 75-90%. I would proceed with salvage RT plus ADT like we did in the era when PSMA was not available.
Do you routinely start anticoagulation for a patient with newly diagnosed hepatocellular carcinoma presenting with a portal venous thrombosis?
No. Anti-coagulation is generally not indicated. Anti-coagulation is usually only indicated for acute PVT causing symptoms. This is more common with underlying thrombophilia. PVT is very common in cirrhosis and anti-coagulation is not required. PV thrombus from tumor similarly is common and anti-coa...

Do you offer prostate RT to men with 0-3 bone metastases on conventional imaging when PSMA PET shows a very high number of M1 lesions?
This would be a hard no from my standpoint.I get the rationale here. STAMPEDE found a survival benefit for prostate-directed RT in men with "low volume" disease, which was defined based on the CHAARTED trial with conventional imaging. Therefore, men with low-volume disease on conventional imaging fi...
How do you approach conversations regarding discontinuation of transfusions in patients with advanced hematologic malignancies who are otherwise appropriate for hospice?
While not an expert in leukemia care or MDS, the answer is nuanced (both in the care of patients and to hospice agencies). Some hospice programs will make exceptions to blood transfusions depending on how frequent - so it is always good to ask. From a clinical perspective, important to consider whet...
