In light of GOG-252, are there any situations where IP chemotherapy would be preferable following debulking of advanced epithelial ovarian cancer?
In GOG-252, the control arm (arm 1) was the dose-dense Japanese GOG (JGOG) regimen, compared to two IP-based arms (arm 2, IP carboplatin, and arm 3, IP cisplatin). As stated in our OGR, interpretation of the negative results of this study is difficult for several reasons. All three arms in GOG-252 r...
Do you perform PDL1 and molecular testing for patients with stages I-III NSCLC?
Do you order PDL1 and molecular testing for patients with stages I-III NSCLC?When I answered this question about two years ago, I said no, primarily because there was no Level 1 efficacy data to support an improvement in outcomes for these patients. This has since changed... although in some ways, n...
Do the results and approval based on ADAURA trial suggest a role for adjuvant osimertinib in patients with stage IIIB-C, EGFR mutant patients treated with concurrent chemoradiation?
ADAURA trial was not designed to address this issue. But that being said, we need to remember few things before considering "maintenance durvalumab" in patients with EGFR-mutant lung cancer, following chemo-radiation: 1. EGFR-mutant NSCLC patients may not derive any clinical benefit from single-agen...
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...
Are there any scenarios you would use CDK 4/6i to treat HR-positive HER2-positive breast cancer in combination with anti-HER2 agents?
There is a strong preclinical data demonstrating that CDK4/6 inhibition reduces the growth of HER2-positive breast cancer cell lines. However, we are still awaiting the results of phase 3 trials testing the addition of CDK4/6 inhibitors to systemic therapy for hormone receptor (HR) positive, HER2 po...
When and how are you incorporating tumor sequencing to plan treatment of metastatic prostate cancer?
Presently, the main categories of actionable DNA based alterations in advanced prostate cancer are 1) alterations in homologous repair enzymes like BRCA2, and 2) microsatellite instability (MSI high status, mismatch repair gene deficiency). These are actionable as they can lead to the use of a thera...
Are there scenarios that new visits/consults with patients can be done virtually amidst the COVID-19 outbreak?
Starting 3/16, we began offering lower-complexity / lower-risk patients the option of having a Tele-medicine consult vs re-scheduling to a later date. This offer has been extended broadly to all new consults at our facility when the provider indicates that s/he can extend comparable service virtuall...
How do you choose which LHRH agonist or antagonist to prescribe for ADT in patients with prostate cancer?
The choice of LHRH agonist or antagonist depends on patient factors. Most patients receive some form of leuprolide or goserelin since these allow longer intervals between injections (as compared to degarelix). Goserelin is used more for those on anticoagulation or with bleeding disorders since it is...
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...
In patients with iron deficiency due to history of gastric bypass or IBD, would you consider oral iron therapy if the iron deficiency anemia is mild?
Oral iron can often be effective in iron deficiency, as long as absorption is intact. If you are concerned about absorption, performing an oral iron challenge can be useful in allowing you to avoid long trials of oral iron that will be ineffective. Simply check an iron panel at baseline, then admini...
