Insights for clinical management from the real-life data of the centralized West of Scotland biliary cancer clinic.

BACKGROUND: With the increasing of novel therapeutics for the treatment of Biliary Tract Cancers (BTC), and the need to assess their socio-economic impacts for national licence approvals, it is as important as ever to have real-life data in national populations. METHODS AND RESULTS: We performed an audit of the first 2 year-activity (Sep 2019-Sep 2021) of the centralized West-of-Scotland-BTC clinic. 122 patients accessed the service, including 68% with cholangiocarcinoma (CCA), 27% with gallbladder cancer (GBC), and 5% with ampulla of Vater carcinoma with biliary phenotype (AVC). Median age at diagnosis was 66 (28-84), with 30% of newly diagnosed patients being younger than 60 years-old. Thirty-five cases (29%) underwent surgery, followed by adjuvant-chemotherapy in 66%. 60% had recurrent disease (80% with distant relapse). Sixty-four patients (58%) started first-line Systemic-AntiCancer-Treatment (SACT). Of these, 37% received second line SACT, the majority of which had iCCA and GBC. Thirty-% of those who progressed received third line SACT. CONCLUSIONS: About 30% of BTC were eligible for curative surgery. Fifty-eight and twenty% of the overall cohort of advanced BTC patients received first and second line SACT. Our data suggest that reflex genomic profiling may not be cost-effective until molecularly driven strategies are limited to second line setting.

Incidence of cardiotoxicity and validation of the Heart Failure Association-International Cardio-Oncology Society risk stratification tool in patients treated with trastuzumab for HER2-positive early breast cancer.

PURPOSE: Trastuzumab improves survival in patients with HER2+ early breast cancer. However, cardiotoxicity remains a concern, particularly in the curative setting, and there are limited data on its incidence outside of clinical trials. We retrospectively evaluated the cardiotoxicity rates [left ventricular ejection fraction (LVEF) decline, congestive heart failure (CHF), cardiac death or trastuzumab discontinuation] and assessed the performance of a proposed model to predict cardiotoxicity in routine clinical practice. METHODS: Patients receiving curative trastuzumab between 2011 and 2018 were identified. Demographics, treatments, assessments and toxicities were recorded. Fisher's exact test, Chi-squared and logistic regression were used. RESULTS: 931 patients were included in the analysis. Median age was 54 years (range 24-83) and Charlson comorbidity index 0 (0-6), with 195 patients (20.9%) aged 65 or older. 228 (24.5%) were smokers. Anthracyclines were given in 608 (65.3%). Median number of trastuzumab doses was 18 (1-18). The HFA-ICOS cardiovascular risk was low in 401 patients (43.1%), medium in 454 (48.8%), high in 70 (7.5%) and very high in 6 (0.6%). Overall, 155 (16.6%) patients experienced cardiotoxicity: LVEF decline ≥ 10% in 141 (15.1%), falling below 50% in 55 (5.9%), CHF NYHA class II in 42 (4.5%) and class III-IV in 5 (0.5%) and discontinuation due to cardiac reasons in 35 (3.8%). No deaths were observed. Cardiotoxicity rates increased with HFA-ICOS score (14.0% low, 16.7% medium, 30.3% high/very high; p = 0.002). CONCLUSIONS: Cardiotoxicity was relatively common (16.6%), but symptomatic heart failure on trastuzumab was rare in our cohort. The HFA-ICOS score identifies patients at high risk of cardiotoxicity.

Recommended antimicrobial therapy for common inpatient infections: a comparative review of guidelines across 51 hospital trusts in England.

BACKGROUND: The number of different antimicrobial recommendations between hospital trusts for the same indication in England is unknown. AIM: We aimed to evaluate the heterogeneity of antimicrobial recommendations for seven common inpatient infections across hospital trusts in England and evaluate changes to recommendations following introduction of national (National Institute for Healthcare and Excellence, NICE) and international (WHO) antimicrobial guidelines. METHODS: Guidelines published on the MicroGuide smartphone application were collected from December 2017 to February 2018 and re-evaluated between December 2019 and February 2020. The following indications were assessed: community-acquired pneumonia (CAP) CURB65 score ≥3, hospital-acquired pneumonia (HAP), infective exacerbation of chronic obstructive pulmonary disease (iCOPD), cellulitis, uncomplicated urinary tract infection (uUTI), intra-abdominal infection (IAI) and sepsis of unknown source (SUS). On follow-up, compliance against WHO WATCH antibiotic and NICE recommendations was evaluated. RESULTS: Guidelines were obtained predominantly from England. Antibiotic regimens between hospitals became increasingly diverse across indications in the following order: uUTI, cellulitis, iCOPD, CAP, HAP, IAI and SUS. A piperacillin/tazobactam-based regimen was recommended in HAP (59%), SUS (39%) and IAI (30%). After 2 years, 107 changes were made to 357 antibiotic regimen recommendations; the overall number of regimens using piperacillin-tazobactam and WHO WATCH antibiotics remained similar. Compliance of recommendations with NICE guidelines as follows: iCOPD (100% adherent), uUTI (98%), cellulitis (90%), CAP (43%) and HAP (27%). CONCLUSION: The heterogeneity of antibiotic recommendations increased as the indicated infection was more severe, with broader underlying bacterial causes. Piperacillin-tazobactam remains favoured in antibiotic regimens, despite not recommended in WHO and NICE guidance.
