Supportive Oncology Care at Home Intervention for Patients With Pancreatic Cancer.

PURPOSE: We sought to determine the feasibility of delivering a Supportive Oncology Care at Home intervention among patients with pancreatic cancer. METHODS: We prospectively enrolled patients with pancreatic cancer from a parent trial of neoadjuvant fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFIRINOX). The intervention entailed (1) remote monitoring of patient-reported symptoms, vital signs, and body weight; (2) a hospital-at-home care model; and (3) structured communication with the oncology team. We defined the intervention as feasible if ≥ 60% of patients enrolled in the study and ≥ 60% completed the daily assessments within the first 2-weeks of enrollment. We determined rates of treatment delays, urgent clinic visits, emergency department visits, and hospitalizations among those who did (n = 20) and did not (n = 24) receive Supportive Oncology Care at Home from the parent trial. RESULTS: From January 2019 to September 2020, we enrolled 80.8% (21/26) of potentially eligible patients. One patient became ineligible following consent because of moving out of state, resulting in 20 participants (median age = 67 years). In the first 2 weeks of enrollment, 65.0% of participants completed all daily assessments. Overall, patients reported 96.1% of daily symptoms, 96.1% of daily vital signs, and 92.5% of weekly body weights. Patients receiving the intervention had lower rates of treatment delays (55.0% v 75.0%), urgent clinic visits (10.0% v 25.0%), and emergency department visits/hospitalizations (45.0% v 62.5%) compared with those not receiving the intervention from the same parent trial. CONCLUSION: Findings demonstrate the feasibility and acceptability of a Supportive Oncology Care at Home intervention. Future work will investigate the efficacy of this intervention for decreasing health care use and improving patient outcomes.

Imatinib-induced hyperbilirubinemia with UGT1A1 (*28) promoter polymorphism: first case series in patients with gastrointestinal stromal tumor.

Imatinib, an orally administered protein-tyrosine kinase inhibitor (TKI) is indicated for the treatment of chronic myeloid leukemia (CML) and gastrointestinal stromal tumor (GIST). Severe hepatotoxicity associated with imatinib is rare, and relationship to polymorphism of uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) expression and related frequency of hyperbilirubinemia or toxicity are not well known. We present a case series patients who developed hyperbilirubinemia while on oral administration imatinib for treatment of GIST. Genetic testing for polymorphism of UGT1A1 showed the first patient to be homozygous for the UGT1A1 TA7 (*28) polymorphism and the second patient heterozygous for the UGT1A1 TA1 (*28) polymorphism. The first patient had to stop imatinib due to severe and persistent hyperbilirubenemia peaking >3 despite reducing imatininb to only 100 mg every other day while the second patient improved at this dose. Our case series represent the first data associating UGT1A1 polymorphism and imatinib in patients being treated for GIST. Given the prevalence of Gilbert's syndrome and the increasing use of imatinib, we encourage physicians to be aware of this possible toxicity as hepatotoxicity can be fatal if not managed in a timely fashion. This association is also timely due to recent FDA requirement for testing UGT1A1 polymorphism for nilotinib, another TKI.

Role of methylphenidate in the treatment of fatigue in advanced pancreatic cancer population.

BACKGROUND: Fatigue is a common but devastating symptom for advanced pancreatic cancer (APC) patients. To date, no proven treatment exists. Methylphenidate (MPH) showed inconsistent results in treating other cancer related fatigue. We performed a retrospective study to assess MPH in ameliorating fatigue in APC patients. METHODS: We retrospectively reviewed our clinic APC patients' records who visited from 06/2011 - 11/2014. Fatigue was assessed by Visual Analog Fatigue Scale (VAFS) and classified as grade 1 (VAFS 1-3), grade 2 (VAFS 4-6) and grade 3 (VAFS 7-10) to correspond with CTCAE V4.0. MPH was dosed at 5 mg daily in the morning and was escalated to 10 mg after 2 weeks if needed. The primary endpoint was to assess the change of fatigue grade after 4 weeks of MPH. Secondary outcomes included MPH's effect on depression, anorexia, maintenance chemotherapy intensity and adverse effects. RESULTS: A total of 71 APC patients on concomitant chemotherapy were included, of whom 67% received doublet, 13% triplet, and 20% single-agent chemotherapy. Mean baseline VAFS was 7, which dropped to 4 after 4 weeks of MPH, 55% patients' fatigue score improved by 1 grade, 8% by 2 grades, 23% had fatigue resolved, 14% without benefit. 72% patients maintained chemotherapy intensity, 39% felt less depression and 52% had improved appetite. 13% stopped MPH due to side effects. Rare Grade 3 or 4 adverse events included insomnia, restlessness, palpitations and anorexia. CONCLUSIONS: Our findings support low-dose MPH benefits APC patients with improved fatigue, depression and anorexia. A large randomized clinical trial is needed to confirm its usage and safety.
