Caregiver experiences in administering subcutaneous medications to community palliative care patients: Integrative review.

As many as 70% of Australian patients report they would prefer to die at home, yet only 14% achieve this goal and this hospitalization adds to overall healthcare expenditure. Providing caregivers with practical means for managing symptoms at home facilitates home deaths for palliative care patients and reduces the financial healthcare burden. The aim of this paper is to understand the experience of caregivers administering subcutaneous medications at home to palliative care patients. An integrative review search of the literature revealed five common themes: positive caregiver experiences and caregiver concerns, symptom management, specialist palliative care support needs, educational requirements, and supporting patients to remain at home. Evidence strongly suggests that with support and education from a palliative care team, caregivers find their experience is empowering and positive. Without support and education, patients are more likely to present to hospital leading to admission and subsequent death not in their place of preference.

Pembrolizumab for advanced nonsmall cell lung cancer: Efficacy and safety in everyday clinical practice.

OBJECTIVES: While pembrolizumab improves overall survival (OS) in a subset of advanced nonsmall cell lung cancer (aNSCLC) patients (pts) in clinical trials, individuals with poor Eastern Cooperative Oncology Group performance status (ECOG PS) were excluded. Furthermore, some studies have identified a potential link between improved pt outcomes and development of immune related adverse events (irAE.) In a large provincial cohort, we studied the efficacy and safety of pembrolizumab for poor ECOG PS pts and whether irAE correlate with improved OS. MATERIALS AND METHODS: aNSCLC pts treated with pembrolizumab between 06/2015 and 08/2018 at BC Cancer were retrospectively identified. Kaplan-Meier curves of OS from initiation of pembrolizumab were plotted. 3-, 6-, and 9- month landmark Kaplan-Meier analysis was performed and log-rank tests used to determine an association of irAE subtypes with OS. Multivariable logistic regression identified variables associated with grade ≥3 irAE within 3 months of pembrolizumab initiation. RESULTS: Of 190 pts, 74.2% were treatment naïve and 92.6% had PD-L1 expression ≥ 50%. Median OS in the 1st line and ≥2nd line settings were 24.3 months (95% CI, 9.7-not reached, NR) and 13.4 months (95% CI, 8.1-NR), respectively. Pts with ECOG PS 2/3 had lower median OS than if ECOG PS 0/1 (5.8 months vs. 16.7 months, p < 0.0001). In multivariable analysis, the odds of grade ≥ 3 irAE within 3 months was 6.3 fold higher if ECOG PS 2/3 versus 0/1 (p = 0.05). Development of pneumonitis at the 9 month landmark weakly correlated with decreased OS (p = 0.09). CONCLUSION: In the studied cohort, ECOG PS 2/3 pts had a significantly lower OS and greater odds of experiencing high-grade irAE than if ECOG PS 0/1. Development of irAE did not result in improved OS. Randomized trials to determine benefit of pembrolizumab for poor ECOG PS pts are needed.

A retrospective review of the multidisciplinary management of medullary thyroid cancer: eligibility for systemic therapy.

BACKGROUND: Medullary thyroid carcinoma (MTC) accounts for 1-2% of all thyroid cancers. The clinical course of metastatic disease can be indolent. Our aim was to characterize the natural history of disease to evaluate the true proportion of patients who would be eligible for the currently available systemic therapies. METHODS: The British Columbia Cancer Agency (BCCA) provides cancer care to a population of 4.6 million. A retrospective chart review was conducted of all patients with MTC referred to the BCCA from 1991 to 2013. Clinical characteristics, pathology, treatment and outcome data were collected. Relapse free survival and overall survival was determined for patients based on staging at the time of diagnosis. RESULTS: Of the 98 patients referred to the BCCA during the study period, inherited mutations were found in 6% though 60% did not undergo genetic testing. Based on clinical SEER staging at diagnosis 50% had localized disease, 38% regional, and 12% had distant metastasis. 77% had complete surgical resection of which 25% received adjuvant radiation therapy. Five year relapse free survival (RFS) for localized and regional disease was 75% and 66%, respectively (p = 0.006). Initial treatment of 23 patients with locally unresectable and metastatic disease predominantly involved multiple modalities. Of the 37 patients with relapsed or metastatic MTC only 7 (19%) patients received one or more course of chemotherapy for metastatic disease: 1 temsirolimus, 2 adriamycin, 3 sunitinib, 3 sorafenib, and 3 vandetanib. Five year OS based on clinical SEER stage: localized 93%, regional 72% and distant 33% (p < 0.001). CONCLUSION: Localized and regional MTC treatment patterns reflect multidisciplinary management based on disease characteristics. Patients with distant disease had poor outcomes with 28% of patients dying from disease. In our cohort the minority of patients ultimately received systemic therapy due to timing and lack of TKI availability.

Investigation of PD-L1 Biomarker Testing Methods for PD-1 Axis Inhibition in Non-squamous Non-small Cell Lung Cancer.

Inhibitors of the programmed cell death 1 (PD-1) signaling axis have recently demonstrated efficacy and are rapidly being incorporated into the treatment of non-small cell lung cancers (NSCLCs). Despite clear benefits to certain patients, the association of these responses with a predictive biomarker remains uncertain. Several different biomarkers have been proposed, with differing results and conclusions. This study compares multiple methods of biomarker testing for treatment of NSCLCs with PD1-axis inhibitors. Tissue microarrays of matched primary and metastatic NSCLCs were used to compare four different PD-1 ligand (PD-L1) IHC techniques, as well as RNA ISH. Additional cases with whole genome and transcriptome data were assessed for molecular correlates of PD-L1 overexpression. Eighty cases were included in the IHC study. Multiple IHC methodologies showed a high rate of agreement (Kappa = 0.67). When calibrated to RNA expression, agreement improved significantly (Kappa = 0.90, p=0.0049). PD-L1 status of primary and metastatic tumors was discordant in 17 (22%) cases. This study suggests that different IHC methodologies for PD-L1 assessment provide slightly different results. There is significant discordance between the PD-L1 status of primary tumors and lymph node metastases. RNA ISH may be a useful adjunct to complement PD-L1 IHC testing.

Multipronged strategy to reduce routine-priority blood testing in intensive care unit patients.

PURPOSE: The purpose of the study is to reduce unnecessary ordering of routine-priority blood tests. METHODS: In this before-after study, we studied all patients admitted to a 15-bed tertiary intensive care unit (ICU) from July 1, 2011, to June 27, 2013. Based on input from intensivists, acceptable indications for ordering routine-priority complete blood counts (CBCs) and electrolyte/renal panels were developed. Sequential interventions were (1) education sessions for ICU housestaff about the lack of evidence for routine-priority blood tests; (2) an item on the ICU rounds checklist to ask if routine-priority blood tests were indicated; (3) a rubber stamp, "routine bloodwork NOT indicated for tomorrow," was used in the chart; (4) a prompt in the electronic ordering system to allow only accepted indications; and (5) a second educational session for ICU housestaff. We measured numbers of tests done before and after these interventions. RESULTS: After introduction of interventions, there were 0.14 fewer routine-priority CBCs and 0.13 fewer routine-priority electrolyte/renal panels done per patient-day. Nonroutine CBCs and nonroutine electrolyte/renal panels increased by 0.03 and 0.02 tests per patient-day, respectively. This overall reduction in tests equates to an adjusted savings of $11,200.24 over 1 year in 1 ICU. There were no differences in demographics, severity of illness, length of stay, or number of red cell transfusions between the 2 periods. CONCLUSION: Sequential interventions to discourage the ordering of routine-priority blood tests in an ICU were associated with a significant decrease in the number of tests ordered.
