Abstract:
Background: We aimed to determine whether continuous auditing of the presumed depth of excision and
comparing with the actual depth of excision in women having large loop excision of the transformation zone (LLETZ) improves the ability to acquire the desired depth of excision.
Method(s): This was a prospective study of women submitted to a single LLETZ treatment between 2017-2018. Two senior colposcopists recorded what they presumed was the depth of excision at the time of treatment and the subsequent histopathology report provided the actual excised depth. Multiple linear regression identified independently associated parameters with the difference between presumed and actual excision depth. Nonlinear regression determined the learning plateau defined as the theoretical minimal score of difference one could achieve with infinite practice.
Result(s): There were significant differences in practices with the first colposcopist using an 18-mm loop and the second colposcopist a 15-mm loop in the majority of cases. The median absolute and percentage difference between the presumed and actual excised depth was 2 mm and 16.6% and 3.5 mm and 35.4% for the two colposcopists, respectively. A learning plateau was identified only for the first colposcopist. We found that auditing consecutive excisions decreased significantly the difference between the presumed and actual depth of excision with a learning plateau at 2.2 mm of absolute difference and 22.6% of percentage difference and with a learning rate of 13 cervical excisions.
Conclusion(s): There might be a benefit in auditing our treatment practice as there seems to be a learning
plateau through this method

Abstract:
BACKGROUND: Results from large randomised controlled trials have shown that adding docetaxel to the
standard of care (SOC) for men initiating hormone therapy for prostate cancer (PC) prolongs survival for those with metastatic disease and prolongs failure-free survival for those without. To date there has been no formal assessment of whether funding docetaxel in this setting represents an appropriate use of UK National Health Service (NHS) resources.
OBJECTIVE(S): To assess whether administering docetaxel to men with PC starting long-term hormone therapy is cost-effective in a UK setting.
DESIGN, SETTING, AND PARTICIPANTS: We modelled health outcomes and costs in the UK NHS using data collected within the STAMPEDE trial, which enrolled men with high-risk, locally advanced metastatic or recurrent PC starting first-line hormone therapy. INTERVENTION: SOC was hormone therapy for >=2 yr and radiotherapy in some patients. Docetaxel (75mg/m2) was administered alongside SOC for six three-weekly cycles. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The model generated lifetime predictions of costs, changes in survival duration, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs). RESULTS AND LIMITATIONS: The model predicted that docetaxel would extend survival (discounted quality-adjusted survival) by 0.89 yr (0.51) for metastatic PC and 0.78 yr (0.39) for nonmetastatic PC, and would be cost-effective in metastatic PC (ICER 5514/QALY vs SOC) and nonmetastatic PC (higher QALYs, lower costs vs SOC). Docetaxel remained cost-effective in nonmetastatic PC when the assumption of no survival advantage was modelled.
CONCLUSION(S): Docetaxel is cost-effective among patients with nonmetastatic and metastatic PC in a UK setting. Clinicians should consider whether the evidence is now sufficiently compelling to support docetaxel use in patients with nonmetastatic PC, as the opportunity to offer docetaxel at hormone therapy initiation will be missed for some patients by the time more mature survival data are available. PATIENT SUMMARY: Starting docetaxel chemotherapy alongside hormone therapy represents a good use of UK National Health Service resources for patients with prostate cancer that is high risk or has spread to other parts of the body.

Abstract:
Background Association between inhaled corticosteroids and pneumonia in COPD population is well known.1 And the risk of pneumonia is greatest with the use of high dose inhaled corticosteroids (HD-ICS).2 Hence, further work to reduce the prescription of HD-ICS should be informed by local practices. Aim We aimed to assess the incidence of pneumonia in COPD patients based at primary practices in our region according to their HD-ICS prescriptions. And thereby develop methods to safely wean off HD-ICS in this population. Methods Data was obtained on all hospital admissions for pneumonia between April-September 2017 with a secondary diagnosis code of J44 indicating COPD, from the head of information at our clinical commissioning group. We divided this data at a general practice level. We also obtained data on prescription of HD-ICS at each of the general practices till September 2017 from openprescribing.net. Statistical results were obtained from MS Excel and Vassar Stats. Results There are 14 general practices in the region. There were 123 pneumonia admissions to hospital with a secondary diagnosis of COPD. This included 50% males (n=62) with a mean age (SD) of 75 (9.7) years. There were 5 practices with >10 pneumonia admissions during this period and when compared with those with <10 pneumonia admissions, the median (IQR) COPD population was 107 patients (103-126) v 47 patients (32-69) [p<0.05] with a median (IQR) use of HDICS prescriptions 239 (170-290) v 108 (86-172) [p<0.05]. Conclusion Our data show an association between HD-ICS prescriptions and pneumonia in COPD population at a primary care level in our region. Having looked at the data including GP practices with higher prescriptions of HD-ICS, we have developed an algorithm (figure 1) to wean patients off HD-ICS while at the same time promoting awareness through local interest group meetings.

Abstract:
Introduction: The objective of this study was to determine the effectiveness and safety of pazopanib in patients with intermediate-risk advanced/metastatic renal cell carcinoma in the PRINCIPAL study (NCT01649778). Patients and Methods: Patients had clear-cell advanced/metastatic renal cell carcinoma and met intermediaterisk International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) and Memorial Sloan Kettering Cancer Center (MSKCC) criteria. Assessments included progression-free survival, overall survival, objective response rate, and safety. We also evaluated effectiveness based on number of risk factors, age, and performance status (PS), as well as safety in older and younger patients.
Result(s): Three hundred forty-three and 363 intermediate-risk MSKCC and IMDC patients were included, respectively. The median progression-free survival was 13.8 months (95% confidence interval [CI], 10.7-18.1 months) and 7.4 months (95% CI, 6.2-10.3 months) for patients with 1 and 2 MSKCC risk factors, respectively, and 13.1 months (95% CI, 10.7-18.1 months) and 8.1 months (95% CI, 6.4-10.7 months) for patients with 1 and 2 IMDC risk factors, respectively. The median overall survival was not reached and was 15.2 months (95% CI, 12.3-26.5 months) for patients with 1 and 2 MSKCC risk factors, respectively, and 33.9 months (95% CI, 33.9 months to not estimable) and 19.4 months (95% CI, 14.3 months to not estimable) with 1 and 2 IMDC risk factors, respectively. A lower overall response rate was observed with Eastern Cooperative Oncology Group PS >= 2 (vs. PS < 2). All-grade treatment-related adverse events occurred in approximately 63% of patients, and the safety profile among older and younger patients was similar.
Conclusion(s): Outcomes with pazopanib in intermediate-risk patients suggest that patients can be further stratified by number of risk factors (1 vs. 2) and Eastern Cooperative Oncology Group PS (< 2 vs. >= 2) to more accurately predict outcomes. Patients with intermediate-risk advanced renal cell carcinoma are a heterogeneous population, having either 1 or 2 risk factors. It is unclear whether all patients in this risk category should be treated similarly. A secondary analysis of the PRINCIPAL study of pazopanib found that patients can be stratified by number of risk factors and Eastern Cooperative Oncology Group performance status to more accurately predict outcomes.
