    Abstract: e15752 Background: Insulin resistance (IR) in pancreatic cancer (PC) patients is associated with cachexia and poor outcome. Pioglitazone (PIO) improves insulin sensitivity via activation of peroxisome proliferator-activated receptor (PPAR gamma). Effects of PIO on insulin sensitivity, glucose homeostasis, and circulating adipokine levels in PC have not been examined. Methods: Patients with metastatic PC were administered PIO 45mg/day orally for 8 weeks concurrent with chemotherapy. Patients with known DM at enrollment were identified Fasting plasma was collected at baseline, weeks 2, 4, 6, 8 of pioglitazone treatment and at 2 weeks-post treatment. The primary objective was to describe changes in indicators of IR, including glucoregulatory hormone levels, glucose tolerance, and inflammatory cytokines. Results: Fourteen patients (age 64y), with a mean BMI of 28 were enrolled. Mean adiponectin increased from baseline to week 8 of treatment (14.2± 3.3 and 46.9±11.4µg/ml, respectively, P ≤ 0.01), and returned to baseline levels at 2 weeks post-treatment (15.1±1.9 µg/ml). Markers of IR (serum glucose, insulin, glucagon, and response to an oral glucose bolus) did not correlate with tumor size, inflammatory cytokine levels, GM-CSF, or CA19-9. A dichotomous response to PIO treatment was observed between non-diabetic and T2DM patients. Fasting insulin increased 70.6±31.3% from baseline to treatment week 8 in patients with T2DM. In contrast, treatment of non-diabetic patients decreased fasting insulin by 40.2±6.3%, demonstrating a significant, P ≤ 0.01, difference in treatment response between PC patients with or without T2DM. Conclusions: We have demonstrated that PC patients respond to 8 weeks of PIO treatment with a significant rise in the insulin sensitizing adipokine, Adiponectin, with a complete wash-out after 2 weeks of cessation. PIO results in opposing fasting insulin responses in non-diabetic and DM patients suggests that diabetes status plays a significant role in the glucoregulatory effects of PIO treatment in PC patients.

    Palliative care and end-of-life health care utilization of pancreatic cancer patients at an urban safety-net hospital.
    American Society of Clinical Oncology (ASCO) ; 2018
    In:  Journal of Clinical Oncology Vol. 36, No. 4_suppl ( 2018-02-01), p. 489-489

    Abstract: 489 Background: There has been an increase in Palliative care utilization in cancer patients. We examined trends of palliative care and intensive care utilization in pancreatic cancer patients in an urban setting safety net hospital. Methods: This is a retrospective analysis of pancreatic cancer patients seen at the Parkland Health and Hospital System between January 1999 and September 2016. Cancer cases and receipt of palliative care were identified from prospectively maintained registries. Health care utilization including intensive care unit (ICU) was reviewed. All statistical analysis was done using IBM SPSS version 24. Results: We identified 455 new diagnoses of pancreatic cancer, mean age 61 years, 227 (50%) female and 228 (50%) white. Of these, 277 (61%) received palliative care ever. Patient who received palliative care were more likely to be younger (mean age, 59.3+-12 vs 62.8 +- 12 years) and have stage 4 disease vs stage 1-3 disease (p 0.006, and p 0.003 respectively). There was no statistically significant difference in palliative care utilization between gender and ethnicity groups. 140 patients had a DNR order and 29 required ICU admission at any point. A first contact with palliative care consult was obtained 〈 = 7 days before death for 29 (10%) patients, 〈 = 30 days before death for 86 (31%) patients, 30-60 days before death for 50 (18%) and more than 60 days before death for 141 (51%) patients. Patients receiving palliative care were more likely to have a DNR status (p 〈 0.001) but had no difference in ICU use within the last 30 days of life (p 0.285). Conclusions: The rate of palliative care in patients with pancreatic cancer in this cohort from a safety net hospital is higher than nationally reported studies. Most patients received palliative care 〉 30 days before death. While patients received early palliative care, it did not result in reduced ICU care. Factors influencing ICU care utilization near the end of life need further study.

    Abstract: 463 Background: FOLFIRINOX therapy is associated with improved outcome in patients with gastrointestinal cancers. The regimen can be associated with significant toxicity and empiric dose modifications are often used. We analyzed 1) real-world prescribing patterns of FOLFIRINOX and 2) toxicity of therapy. Methods: Patients undergoing FOLFIRINOX chemotherapy at an academic, NCI-Designated Comprehensive Cancer Center were identified and electronic medical records reviewed. Patients who received at least one dose of FOLFIRINOX were included. Chemotherapy dose, growth factor use and toxicity data was abstracted for the first 8 weeks. ‘Standard FOLFIRNOX’ was defined as the regimen utilized by Conroy et al (NEJM 2011). Any empiric reduction/withholding of drug dose for cycle 1 was classified as ‘modified FOLFIRINOX’. Bivariate analysis was performed on the data. Results: There were 111 patients seen between 5/2011-3/2017 and 94% had pancreatic cancer. Age range was 29-87 years and 52% were female. 59% received ‘modified FOLFIRINOX’ and 20% received empiric growth factors. Line of therapy for standard vs modified respectively was 71.1% vs 45.5% for 1st, 17.8% vs 36.4% for 2nd, and 11.1% vs 18.2% for beyond 2nd (p = 0.03). Patients with ‘modified FOLFIRINOX’ were more likely to have metastatic disease (p = 0.01), have received second line or beyond, and higher ECOG score (p = 0.03). Patients with ‘modified FOLFIRINOX’ had a trend toward fewer treatment-related ED visits or hospitalization vs ‘standard FOLFIRINOX’ (27.2% vs 42.2% p = 0.10) and fewer treatment delays (25.8% vs 42.2% p = 0.07). Conclusions: In the real world setting, a majority of patients on FOLFIRINOX receive empiric dose modifications. Although modified dose did not translate to a significant difference in ED visits, hospitalizations or treatment delays, there was a trend toward fewer events.

    Interaction between regorafenib and warfarin therapy.
    American Society of Clinical Oncology (ASCO) ; 2017

    Abstract: 651 Background: Regorafenib is an oral multi kinase inhibitor with clinical activity in colorectal cancer, gastrointestinal stromal tumors and hepatocellular cancer. Drug- drug interactions are commonly encountered in clinical practice and warfarin continues to be the most commonly prescribed anticoagulant among cancer patients in the clinic. The interaction of regorafenib with warfarin has not been studied. Methods: Patients at a single institution being prescribed regorafenib were identified and charts reviewed for concurrent warfarin therapy. Baseline characteristics, indications for regorafenib and warfarin therapy was determined. Patients were followed up to the first 8 weeks of combination therapy. Results: We identified 6 patients on concurrent regorafenib and warfarin. All patients had refractory colon cancer. Median age was 74, 4 were male and 5 white. Indication for warfarin was venous thromboembolism in 5 and atrial fibrillation in 1. Baseline INR ranged from 1.1 to 2.4. An increase in INR was seen in all six patients (peak INR range 4.5 to 〉 12) which improved with dose modification. Time to peak INR was less than 6 weeks (INR trends in all patients shown in figure 1). There were no bleeding complications noted in any patient. Conclusions: We report a clinically significant interaction between warfarin and regorafenib with patients demonstrating an increase in INR. Patients who are anticoagulated with warfarin and start regorafenib should be closely monitored and upfront warfarin dose reduction should be considered. Further drug-drug interaction studies are needed to determine the exact mechanism of drug-drug interaction between these medications.
