How does the CLL17 trial presented at ASH 2025 change current practice guidelines?
The CLL17 study provides some tangential support for time-limited therapy in a subset of patients that I would consider now--those who have low-risk disease with IGHV mutated (non-3-21) and absent TP53 mutation or deletion. Here, we would expect patients to do quite well, and long-term follow-up exi...
Is there benefit to aggressively treating hemochromatosis in a patient who has already progressed to cirrhosis at the time of diagnosis?
The short answer is yes, there is a benefit to treating iron overload in a patient with hereditary hemochromatosis (HH) with cirrhosis. HH involves at least five mutations, most commonly in the HFE gene (common variants include C282Y and H63D), leading to hyperabsorption of iron and progressive accu...
For primary CNS lymphoma, when do you refer for whole brain radiation therapy (WBRT)?
When data are limited, consensus guidelines tend to rely on the personal clinical experiences of the guideline committee members. That may explain the NCCN guidelines. Recently, remarkable progress has been noted in the treatment of CNS lymphoma with drugs alone. Ibrutinib is particularly effective ...

What is the rationale for the recent change in the NCCN criteria for very high risk prostate cancer?
As the new Chair of NCCN's Prostate Cancer Guidelines, I am happy to answer this.The purpose of risk groups is not merely to be a prognostic divider, but to help guide treatment. Many systems have been developed that have greater prognostication than NCCN risk groups, such as STAR-CAP (which is supe...
Are you comfortable combining relugolix with enzalutamide or abiraterone?
I usually avoid these combinations. The challenge is that relugolix is not superior to other ADT methods in terms of efficacy (at least based on available data) but there are safety issues with considering these combinations. All three of these medications are substrates for similar enzymatic metabo...
Is there a role for peritoneal debulking in patients with peritoneal metastases from colorectal cancer?
This is a great question.Peritoneal metastasis (PM) is the 3rd most common site of colorectal cancer recurrence after liver and lung. PM is listed as M1c by the current AJCC staging. The best treatment approach is still uncertain. The current NCCN guidelines recommend "Complete cytoreductive surgery...
How do you approach patients with stage III unresectable, combined histology NSCLC/SCLC?
For stage III lung cancer with mixed NSCLC and small-cell lung cancer, we treat patients with concurrent chemotherapy (cisplatin/etoposide every three weeks) and definitive radiotherapy (60-66 Gy in 30 fractions, QD), followed by adjuvant immunotherapy (durvalumab). The rationales are as follows: Ra...
Would you consider neoadjuvant immunotherapy prior to radiation for a locally advanced skin squamous cell carcinoma?
While the definitive trials are yet outstanding and enrollment in NRG HN0014 (NCT06568172) should be encouraged where it is open, the present indications for using cemiplimab should follow its principal indication, unresectable cutaneous squamous cell cancer, a minority of cases at 5%. Practically s...
How would you approach a referral for concern for hemochromatosis with ferritin elevation but otherwise normal iron studies?
Interesting questions, but lack of specifics about the degree of elevation and what constitutes normal iron studies makes it difficult to directly answer this question. However, there are well-recognized causes of elevated ferritin due to non-iron overloaded conditions, including increased apoferrit...
