Can RT to non-bulky sites be omitted in an early stage (stage I or II) classical Hodgkin's lymphoma case with a CR by PET/CT?
Randomized studies have consistently demonstrated that combined modality therapy is superior to chemotherapy alone in regards to progression-free survival in early-stage Hodgkin lymphoma. The magnitude of the benefit varies across studies, but a relative risk reduction of ~50% can be expected which ...

Is it reasonable to treat a solitary plasmacytoma of the lung parenchyma with SBRT?
I have only treated one patient with solitary plasmacytoma of the lung over the past 15 years of doing lung SBRT. It is an extremely rare and unusual disease presentation for myeloma. Given the radiosensitivity of myeloma, I opted for 30 Gy in 5 fractions, which resulted in a completed response in t...
How do you approach a patient with indolent, small-volume, but slowly progressive lung mets from sarcoma?
If small volume without active extrapulmonary disease and amenable to addressing all lesions with SABR, surgery, or a combination of both, I would target all lesions with local therapy. If the above conditions are met, these can often be monitored closely with q3-6 month CT surveillance in the prese...
Under what circumstances would you start steroids for a patient with a new brain tumor prior to biopsy or resection?
Agree. As a corollary, if lymphoma is suspected, do NOT use steroids before diagnostic confirmation unless there are severe symptoms or significant mass effect. If steroids are unavoidable, diagnostic confirmation should be pursued within days due to the lymphotoxic effects of steroids decreasing di...
Should cisplatin, gemcitabine, and veliparib be the standard of care in treating metastatic/unresectable pancreatic cancer with BRCA or PALB2 mutation?
In a recent publication (O’Reilly et al. JCO 2020), the authors reported high response rates (74.1% vs. 65.2%, respectively) of both study arm (gemcitabine + cisplatin + veliparib) and control arm (gemcitabine + cisplatin) from a phase II open-label, randomized multicenter trial. Despite the unprece...
What is the current role for genetic profile testing (e.g. DecisionDx-SCC) in the treatment paradigm for cutaneous malignancies?
This is a very cool test that has a lot of potential to help us make decisions in practice (full disclosure, I advise Castle and get research support from them, but am not directly compensated by them). The data published thus far shows that it is prognostic to predict nodal or distant mets. However...
How do you treat non-spine bone oligometastases?
Get the MRI. It is proven to reduce inter-observer variability in contouring (Raman et al., PMID 29748100). More philosophically, sometimes you'll see something more, sometimes you won't. But the only way to know is to check. And if this treatment is worth doing, it's worth doing accurately -- espe...
Would you recommend chemoimmunotherapy for metastatic anal squamous cell cancer?
Anal canal squamous cell cancer (SCC) is a relatively uncommon disease, with approximately 10,000 new cases in the United States annually. Chemoradiation treatment is curative for a significant percentage of patients. The rate of locoregional failure was reported to be 10% to 30%, and th...
How would you manage a patient less than 40 years old with an incidentally found LGG, IDH mutated, 1p19q intact, s/p STR?
Update: On August 6, 2024, the FDA approved Vorasidenib for IDH-mutant low-grade gliomas based on findings from the INDIGO trial. This decision highlights the FDA's incompetence and lack of scientific integrity, clearly demonstrating that the agency prioritizes pharmaceutical companies' interests ov...
