Are there still clinical situations in which you deliberately treat patients with a DOAC besides apixaban?
Thank you for your question. Apixaban has been my preferred agent for a long time for patients requiring therapeutic anticoagulation. Apixaban’s lower bleeding risk was shown prior to and now has additional evidence to support this with the COBRRA trial. The risk is also ameliorated by the safety in...
How do you counsel patients on the risks and benefits of chemotherapy or radiation offered with palliative intent?
Before I start counseling a patient on these decisions, I want to know a few things first. I would want to know from the oncologists what they think the benefits are (i.e., how much more time might they get? Symptom control?) and what the risks are. The chances that the patient will see a benefit. ...
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...
For gross hematuria from a primary bladder tumor, what palliative radiation regimen would you recommend?
I found that 36 Gy/6 Fx delivered weekly is a great option for palliation.This has been used in curative system, as well, but I find it to be particularly helpful in elderly patients or those with travel issues. There is a phase 2 study in patients who are medically inoperable and the local control ...
Given the final publication of NSABP B-51, for which patients meeting trial eligibility would you still recommend regional nodal irradiation?
The very first thing that should occur before one makes a decision about what they are going to do is to understand how the trial was designed and who was actually accrued to it. The first point is that B51 was a superiority and not a non-inferiority trial. A very related point to that is that they ...
Would you give a PARP inhibitor, and at what dose, to a patient with end-stage renal disease on hemodialysis after completion of 6 cycles of carboplatin and paclitaxel for advanced ovarian cancer?
This is an interesting question, for which I don't have a quick answer.When it comes to PARP inhibitors (PARPi), there is compelling data for its use as maintenance therapy as well as recurrent treatment. The article by Kurnit et al., is a nice summary of the data available supporting PARPi use (Kur...
How long do you continue trastuzumab and pertuzumab after lumpectomy if you included both in a neoadjuvant regimen such as TCH-P?
A total of one year for trastuzumab, including the part with chemotherapy, adjuvant or neoadjuvant. The benefit from addition of pertuzumab, as might have been predicted, was very small, since it is very hard to add any sizable benefit to trastuzumab without some logical risk stratification; for ER ...
When do you choose a non-anthracycline containing regimen, such as docetaxel/cyclophosphamide, for patients with hormone receptor positive, HER2 negative breast cancer who warrant adjuvant chemotherapy?
As in many of the decisions we face, we need to balance benefit and risk. Based on the ABC suite of trials, anthracycline regimens are slightly more effective than non-anthracycline (taxane only) regimens. To be clear, the ABC data is far from perfect - the trial design changed at least 3 times duri...
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.
Would you consider use of PARP inhibitors in patients with metastatic breast cancer with moderate penetrance germline mutations such as CHEK2, ATM, RAD51?
In the Olaparib Expanded (TBCRC 048) study published by @Dr. First Last in JCO, there were no responses to olaparib in metastatic breast cancer with germline or somatic CHEK2 or ATM pathogenic variants (mutations). In contrast, responses were seen in metastatic breast cancer with PALB2 pathogenic va...
