Would you recommend adding a mineralocorticoid receptor antagonist or endothelin receptor antagonist for a patient with bevacizumab-induced proteinuria who is already on an ACEi or ARB?
Unfortunately, we have no data to guide the choice of anti-proteinuric agents in this particular setting. We do have biological plausibility for antagonizing the endothelin pathway, as we know that vascular endothelial growth factor inhibition results in upregulation of endothelin-1, and the resulta...
What are your top takeaways in Radiation Oncology from SABCS 2025?
Several significant studies were presented at San Antonio this year. I will focus on the three most important abstracts reporting new data from studies of local-regional therapy. (The 10-year update of the BIG 3-07-TROG 07.01 trial comparing hypofractionated and conventional fractionation and the us...
Would you consider immunotherapy in high-risk resectable MSI-H colorectal cancer?
Immunotherapy demonstrated great activity in treating metastatic MSI-H colorectal cancer (CheckMate 142 study, KEYNOTE-177 study, etc). There are now several small studies showing the activity of immunotherapy in early stage or locally advanced colorectal cancer. The NICHE study enrolled 40 patients...
What non-variceal EGD findings, if any, deter you from using atezo/bev in patients with advanced HCC?
I would discuss the severity and risk of bleeding with the endoscopy team and start beta blockers as indicated before starting anti-angiogenesis therapy.
Should all patients diagnosed with B12 deficiency get a baseline EGD?
It is important to determine the cause of B12 deficiency. The majority of cases are due to pernicious anemia (atrophic gastritis and lack of intrinsic factor), I presume this question relates to that group. If there is another cause such as intestinal malabsorption or bacterial overgrowth, this does...
How have you incorporated ctDNA into the clinical management of patients with gynecologic cancers?
ctDNA certainly is increasing rapidly in oncology and has been led by several other disease sites. I think right now, GYN oncology is figuring out how to incorporate this in our care to meaningfully impact our patients. I have not incorporated ctDNA in my practice routinely, but do see the role of i...
How do you sequence antiviral therapy and cancer-directed therapy in a newly diagnosed patient with hepatocellular carcinoma and incidentally found hepatitis C?
According to the recent publication by Cabibbo G, et at, J. Hepatol. 2019, 71, 265–273, yes direct-acting antivirals after successful treatment of early hepatocellular carcinoma improves survival in HCV-cirrhotic patients. No such data or evidence for advanced disease though. in that case, antiviral...
How would you approach a patient with Stage III gastric cancer and poor performance status who had large residual disease (ypT4N1) after neoadjuvant capecitabine and was later found to be MSI-H?
We are flying in the "no data" zone here. The MATTERHORN study, led by Dr. Janjigian et al., is a global 948-patient study in which patients with resectable gastric/GEJ adenocarcinoma received perioperative FLOT +/- perioperative (neoadjuvant/adjuvant) durvalumab. The press release on 6/2/23 showed ...
In patients with inflammatory bowel disease with low rectal cancer with planned proctocolectomy, would you consider creation of a pouch?
This is a very difficult case- are you speaking of Ulcerative Colitis or Crohn's disease? If UC - can consider pouch but really depends on the stage of the primary rectal cancer. If neoadjuvant chemoradiation is given, the likelihood of an ileoanal J-pouch functioning appropriately is low. Generally...
How will you use Pola-R-CHP in the frontline treatment of DLBCL?
Given the comparable toxicity profile and the lower rate of treatment failure, the number needed to treat (n=16) is low enough that this is very appropriate to be the new standard of care. Although overall survival was not different, fewer patients treated with the Pola-R-CHP regimen required subseq...
