A Collection of Hematology & Oncology Articles
The practice of oncology and hematology is in constant evolution. These articles highlight some of the most notable advancements and discoveries in the modern medical world. We invite you to use this site frequently and collaborate with medical professionals across the globe.
Welcome
At Florida Cancer Specialists & Research Institute (FCS), our physicians and advanced practice providers are deeply vested in clinical research to provide the most cutting-edge treatment options available to our patients. In our own practices we are fortunate to offer over 300 clinical trials across 37 locations including 3 dedicated Phase 1 Drug Development Units. We value every opportunity to share best practices and the latest research both within and outside of our institution. We welcome you to use this collection as a resource to support your own research and understanding as we strive together to advance cancer care one step at a time.

Utility of the 70-Gene MammaPrint Assay for Prediction of Benefit From Extended Letrozole Therapy in the NRG Oncology/NSABP B-42 Trial
MammaPrint did not predict distant recurrence, but it did predict patients who may benefit from extended hormonal therapy. We do have breast index, so now we have options. Breast index can predict the possibility of recurrence though by helping to determine the level of risk.
Overall Survival with Pembrolizumab in Early-Stage Triple-Negative Breast Cancer
This study confirms what we saw in initial reports showing the addition of pembro increasing the rate of ypathological complete response (ypCR’s) in the neoadjuvant setting for triple-negative breast cancer (TNBC). New data shows a 5% improvement (87 vs 82%) in overall survival (OS) with the quadruplet. Higher gains but at higher cost of toxicity. The fact that adjuvant intraosseous (IO) does not seem to improve outcomes, but neoadjuvant chemo+IO does show intact tumor-immune interactions to create maximum treatment effectiveness is most likely real. Of note, this seems mostly independent of programmed death-ligand 1 (PDL1) status.
Nivolumab plus Ipilimumab in Microsatellite-Instability–High Metastatic Colorectal Cancer
Here is a large phase-III well done study confirming what we knew from earlier studies, that ipilimumab plus nivolumab (Ipi+Nivo) is highly active and effective in the microsatellite instability-high metastatic colorectal cancer (MSI-high met-CRC) population. This is most likely more effective than single agent IO therapy but with higher rates of toxicity. When all things are equal, I would consider this to be the standard of care (SOC) in this context.
Perioperative Durvalumab with Neoadjuvant Chemotherapy in Operable Bladder Cancer
Perioperative durvalumab showed an improvement of 2-year OS of 82.2 vs 75.2%, 2-year PFS was improved 67.8 vs 59.8%. There was interestingly no difference in the rates of grade 3-4 toxicity in the SOC vs periop-IO group. This is likely going to become the SOC in resectable bladder cancer.
A Multicenter Phase II Trial of Ruxolitinib for Treatment of Corticosteroid Refractory Sclerotic Chronic Graft-Versus-Host Disease
Most of us don’t have many autologous stem cell transplant (Auto-HSCT) patients whom we follow, but this topic seems ripe for an American Board of Internal Medicine (ABIM) question. Ruxolitinib seems quite effective for steroid refractory sclerotic chronic graft-versus-host disease (cGHVD).
Inebilizumab for Treatment of IgG4-Related Disease
Cool drug in an uncommon disease but one we may encounter at some point in our careers. Inebilizumab is a CD-19 monoclonal antibody (Mab) that is quite effective in controlling the inflammatory process in IgG4-related immune-mediated fibroinflammatory disorders.
Addition of Metastasis-Directed Therapy to Systemic Therapy for Oligometastatic Pancreatic Ductal Adenocarcinoma (EXTEND): A Multicenter, Randomized Phase II Trial
Interesting study using local therapy in metastatic pancreatic ductal adenocarcinoma (MPDAC) patients with <=5 metastatic sites. I would really like to see overall survival data here as I think progression-free survival (PFS) is a tricky endpoint to use in a trial like this. Most likely the study arm will take a lot longer to demonstrate progression if all lesions are ablated, but most important to me is the quality of life, survival and overall exposure to cytotoxic therapy; the last of which is likely much better with local therapy being utilized.
Oxaliplatin Added to Fluoropyrimidine/Bevacizumab as Initial Therapy for Unresectable Metastatic Colorectal Cancer in Older Patients: A Multicenter, Randomized, Open-Label Phase III Trial (JCOG1018)
This Japanese study showed no benefit with the addition of oxaliplatin to fluoropyrimidine plus bevacizumab (5FU+bev) in patients who were aged 70-74 but unfit, or >=75. Interestingly survival was actually shorter in the patients who received oxaliplatin at 21.3 vs 19.7 months.

Plasma Proteome–Based Test for First-Line Treatment Selection in Metastatic Non–Small Cell Lung Cancer
FCS medical oncologist and hematologist Ernesto Bustinza-Linares, MD has co-authored an abstract published in the American Society of Clinical Oncology Journal, JCO Precision Oncology, that uncovers a new testing method to determine personalized care options for patients with metastatic non-small cell lung cancer (NSCLC). The abstract’s authors address the limitations of existing guidelines that recommend checkpoint immunotherapy, sometimes in combination with chemotherapy, for treating NSCLC, which often discounts patient variability and immune factors. The findings from the study show that by incorporating additional plasma proteome-based testing, combined with the standard protein inhibitor testing, clear differences in patient outcomes were observed after applying targeted treatments based on the testing results.
