When do you choose dose-dense chemotherapy v. q3 week therapy in advanced epithelial ovarian cancer?
In our recent OGR, we suggested an approach to deciding which patients might be appropriate for considering the dose-dense regimen in the first line setting (Figure 2). The dose-dense JGOG regimen was shown to confer an overall survival advantage in newly-diagnosed patients with advanced disease (es...
How do you choose among the available PD-1/PDL-1 inhibitors approved for metastatic bladder cancer?
This is an evolving field. While the thought had been all the drugs were likely equivalent in efficacy (with no head to head trials) this has changed in the past week. Roche had a press release in which they announced the Phase III IMvigor211 study that evaluated atezolizumab in people with locally ...
Is there any role for bisphosphonate or alternative bone-modifying agents use in SMM in the absence of other indications for its use?
The short answer is no, unless the patient has an indication like osteoporosis. Bisphosphonates have been evaluated in smoldering multiple myeloma in studies performed over 10 years ago. Treatment with pamidronate (D’Arena et al., 2011) or zoledronic acid (Musto et al., 2008) did not affect the time...
Is it acceptable to treat patients with limited, asymptomatic brain metastases and EGFR-mutant NSCLC with upfront TKI?
Though some clinicians have been exploring the idea of targeted therapy for EGFR mutant brain metastases, this has been done in the absence of strong evidence. Reasons for pushing this idea are that sometimes the lesions seem to respond, and this has been seen in some single arm studies and anecdota...
Given the recently published results of PEACE 2, under what scenario would you offer pelvic radiotherapy for high-risk/very high-risk prostate cancer?
Although PEACE-2 was presented at GU ASCO, to my knowledge it has not yet been published other than in abstract form, and the results of the arms in PEACE-2 comparing prostate only vs whole pelvic RT were not presented, so I don't think PEACE-2 sheds any light yet on the question of whether or not t...
How does data from the HIMALAYA trial impact your first line treatment selection for advanced HCC?
The results from the HIMALAYA trial with the combination tremelimumab (CTLA-4 inhibitor) and durvalumab (PD-L1 inhibitor) reported an OS of 16.4 months compared to 13.8 months for sorafenib which was statistically significant (HR 0.78, p-value of 0.0035). With the limited data presented at ASCO GI 2...
When do you recommend PD-L1 testing for patients with recurrent cervical cancer?
I think getting the testing done as soon as possible is best because very few patients will only need first line therapy. This way, there is less of a delay at the time of progression following/during first-line therapy.
Should we be stopping new starts of patients who can be triaged for 2-3 months like prostate cancers on ADT when significant community spread of COVID-19 is detectable in our area?
I would for those patients requiring ADT, which is the way I interpreted the question. I want to elaborate more because @Dr. First Last brought up other scenarios we should consider and he brings some more good points: Many patients could get active surveillance for a period of time before ADT is co...
How would you approach a patient with a recent MI s/p DES who is being considered for neoadjuvant chemotherapy for TNBC?
This is mostly opinion as there is not data specific to this situation. First, I would coordinate closely with the cardiologist, preferably someone with knowledge of cardio-oncology. Presumably the patient is already on cardioprotective medications, such as beta blocker and ACE inhibitor, but if not...
Are CHEK2 mutations a contraindication for breast conservation therapy with lumpectomy + RT?
Among women with early-stage breast cancer and moderate penetrance breast cancer susceptibility genes, such as CHEK2, decisions about breast surgery are largely based upon personal preferences. According to data from large population-based studies, women with CHEK2 pathogenic variants have about a 2...
