What is your preferred first line treatment option for a fit patient with non-squamous NSCLC who is PDL1 positive (1-49%) with no driver mutations?
My preferred first line option for patients with advanced NSCLC and PDL1 TPS score of >1% and <50-% remains chemotherapy with immunotherapy. I prefer carboplatin- pemetrexed -pembrolizumab for nonsquamous and carboplatin-taxane-pembrolizumab for squamous cell NSCLC. I might consider Nivolumab Ipilim...
Would you recommend 3 or 6 months adjuvant chemo for low risk Stage III sigmoid cancer (T3/N1), but with positive LVI and PNI?
I would recommend 3 months of CAPOX in this case. For a patient with stage III colon cancer, the presence of LVI and PNI should not influence the treatment plan.
How do you choose 1st line therapy for recurrent cervical cancer?
I use the Moore criteria and if the score is greater than or equal to 2, I will evaluate the patient for contraindications to bevacizumab and if none, I will counsel her to receive bevacizumab plus chemotherapy. The chemotherapy backbone is cisplatin-paclitaxel if the patient did not receive cisplat...
Which group of Stage III MSI-H colon cancer patients can be excluded from receiving adjuvant chemotherapy?
10% to 15% of patients with early-stage, and 4% of patients with metastatic colorectal cancer (CRC) test positive for dMMR. In stage II-III colon cancers, MSI-H/dMMR status is predictive of resistance to 5-fluorouracil as monotherapy, (Sargent et al., PMID 20498393) such that the addition of oxalipl...
In mCRPC patients who had an initial response to Pluvicto but progress within 12 months, where do you position PSMA radioligand retreatment relative to other next-line systemic options in your sequencing strategy?
For such a clinical situation, consideration of retreatment with PSMA radioligand therapy is evolving. There are currently phase II trials at UCLA Health (RE-LuPSMA) and in France (ReaLuP) for patients with a previous favorable response to Lu-PSMA that will assist in building the experience with suc...
Is there a role in sending liquid biopsy for patients progressing on ALK inhibitors?
We believe there is increasing value in testing for acquired resistance mechanisms and thereby sending liquid biopsies in patients who progress on ALK inhibitors. The importance was not previously observed as much in patients who progress on first generation crizotinib, since many patients will resp...
How do you manage therapy in an elderly, >80 years of age, patient with triple-negative breast cancer that is not a surgical candidate?
Treatment decisions for these patients can best be made based on geriatric assessment, estimated life expectancy, whether the treatment goal is prolonged survival or palliation, the potential benefits and toxicities of a specific treatment, and the patient’s personal goals for treatment. The number ...
Would you expect a reduced neutrophil count in individuals with a partial duffy null phenotype?
The Duffy null phenotype's impact on neutrophil counts is "all or none". Approximately one-third of patients with the Duffy null phenotype Fy (a-b-) will have a neutrophil count below the usual lower limit of normal. The range of neutrophil counts in individuals with Fy (a+b-) and Fy (a-b+) is exact...
Do you consider NSCLC with multistation N2 involvement appropriate for treatment with neoadjuvant chemoimmunotherapy followed by surgery?
Interesting question and something that is frequently discussed in tumor boards. Multistation N2 patients were not included in neoadjuvant trials and hence, any adaptation of this strategy to patients with advanced N staging would not be appropriate at this time. Further, given level 1 evidence from...
How would you approach a stage 1 HR+/HER2- pre-menopausal patient <50 years old with Oncotype DX RS of 24?
All the prior comments are very reasonable. It is hard to completely exclude a small absolute benefit from chemotherapy in this group. The trial's subset analyses aren't designed to definitively answer whether ovarian suppression or direct action of the chemo led to the observed risk reduction in <5...
