Would you extend pembrolizumab for over 2 years in a patient with MSI-H pancreatic ductal adenocarcinoma with now-stable disease?
I usually don't, but admittedly, this is a "data-free zone" in the pancreas. I would just stop and watch carefully with scans and tumor markers and have a low threshold to resume or biopsy if it looks like there is progression.
What would be the next step if a patient’s serum testosterone remains above 40 several weeks after the initial dose of a GnRH agent in the treatment of prostate cancer?
Real-world data show that approximately 3-7% of patients experience breakthroughs above 40 ng/dL per patient course, while 6.6% experience breakthroughs above 32 ng/mL (1.1 nmol/L). When using the lower threshold of 20 ng/dL (0.7 nmol/L), breakthrough rates increase to approximately 41%. One large r...
How would you sequence treatment (chemo and chemoRT) for a patient with a very symptomatic locally advanced rectal adenocarcinoma, MSS, with involved pelvic nodes and a mass abutting the sphincter, with no distant disease on CT but marked elevation in CEA above 300?
A pretreatment CEA level above 300 ng/mL is far beyond the typical range seen in stage II–III disease and warrants aggressive investigation. PET/CT should be strongly considered in this case to exclude occult distant disease, as it can change management in 8–11% of patients and is specifically recom...
Has the data for the ENRICH study changed your practice for the initial treatment of mantle-cell lymphoma?
While the information presented was intriguing, it has not yet caused any change in my approach to initial therapy for MCL. I say this due to the fact that the IR arm did not seem better than BR, save for those with a P53 mutation. I have routinely avoided CIT in this patient population, so this inf...

Should GLP-1 agonists be held during chemotherapy?
I think there are several aspects to this question. First, is there evidence that as a class GLP-1 RAs increase the risk of cancer or worsen prognosis during cancer? I could find nothing to raise concerns about outcomes. One recent report even showed a decreased risk of some cancers with GLP-1 RA co...
In light of data from TRIANGLE, ECHO, and ENRICH, what is the best strategy to treat newly diagnosed patients with the blastoid variant MCL?
The management of MCL for almost 2 decades was driven by extrapolated data from aggressive B-cell lymphoma. However, aggressive chemotherapy and stem cell transplantation have failed to produce a plateau on overall survival curves, and patients inevitably have relapsed. It is now clear that MCL, par...

What is your approach to treatment of mantle cell lymphoma in someone with a mutated gene downstream of the BTK receptor, such as mutated CARD11?
For those with primary refractory MCL after a cBTKi, I would still not proceed with chemotherapy, given the limited data to support benefit after a patient progresses on a cBTKi. Only data thus far is with a bendamustine/cytarabine-based regimen, which, if/when they relapse, would potentially impact...
