Pharmacists' involvement in COVID-19 vaccination across Europe: a situational analysis of current practice and policy.

One year since the emergence of the COVID-19 pandemic, rapid response measures have been implemented internationally to mitigate the spread of the virus. Following rapid and successful pre-clinical and human trials, several vaccines have been authorised for use across Europe through the European Medicines Agency and national regulatory authorities. Clinical trials have shown promising results including important reductions in disease severity, hospitalisation and mortality. In order to maximise the public health benefit of available vaccines, there is a pressing need to vaccinate a large proportion of the population. Internationally, this has prompted coordination of existing services at enormous scale, and development and implementation of novel vaccination strategies to ensure maximum inoculation over the shortest possible timeframe. Pharmacists are being promoted as healthcare professionals that enhance roll-out of COVID-19 vaccination programmes. This paper aims to summarise current policy and practice in relation to pharmacists' involvement in COVID-19 vaccination in 13 countries across Europe.

Efficacy of biological agents in metastatic triple-negative breast cancer.

Metastatic triple-negative breast cancer (mTNBC) represents 15% of invasive breast cancers. Prognosis is poor, and there is no specific target therapy but biological agents combined with chemotherapy may be effective. To assess the role of biological agents in metastatic triple-negative breast cancer we performed a systematic review of phase III randomized controlled trials published from January 2006 to February 2013 and presentations at ESMO, ASCO, and SABCS congresses in 2010-2012. We consulted PubMed and ClinicalTrials.gov. Only studies comparing biological agents and chemotherapy versus chemotherapy alone were considered. Relevant statistical variables were log of the hazard ratio and relative variance for progression-free survival (PFS) and overall survival (OS). Of 353 PubMed publications and 229 studies registered on ClinicalTrials.gov, 10 trials were selected and 5293 patients were analyzed: 1546 had mTNBC. Biological agents considered were bevacizumab, sunitinib, sorafenib, lapatinib, iniparib and cetuximab. In addition, a meta analysis of the four studies containing bevacizumab was performed and it showed a PFS improvement with a relative risk reduction of 35% (95% CI: 25-43%). No effect on OS was observed. No PFS and OS benefit was detected with the other agents. No improvement of OS was detected in patients treated with biological agents plus chemotherapy, while a significant PFS improvement was observed only for bevacizumab and cetuximab. The overall impact of these agents on patient survival was not as great as expected, probably because the molecular basis of this illness needs to be better understood so that treatment can be more appropriately tailored.

Lung infiltrates in cancer patients: differentiating metastases from bronchiolitis obliterans organizing pneumonia.

Bronchiolitis obliterans organizing pneumonia (BOOP) is a rare condition that affects oncological patients, often during or after chemotherapy, and can easily be mistaken for lung metastases. BOOP should be taken into consideration in cases when patchy nodular infiltrates with uncertain behavior appear in the lung; these infiltrates are often unresponsive to treatment with antibiotics. We report a case in which a patient treated for transitional cell bladder carcinoma with surgery and adjuvant chemotherapy developed multiple bilateral pulmonary nodules one month after the end of treatment.

Risk/benefit profile of bevacizumab in metastatic colon cancer: a systematic review and meta-analysis.

BACKGROUND: Bevacizumab, an anti vascular endothelial growth factor antibody is licensed in several tumours and widely used in colorectal cancer. However, bevacizumab has several adverse effects which may appear unexpectedly and differ according to the tumour. AIMS: The aim of this work is to quantify the overall risk of bevacizumab-related side effects in patients affected by advanced colorectal cancer and to compare them with its overall benefit. METHODS: We performed a systematic review and meta-analysis investigating bevacizumab in metastatic colorectal cancer. Our primary endpoint was safety and secondary endpoints were overall survival and progression-free survival. The relative risks for side effects were calculated with their 95% confidence interval using the inverse of variance method. For statistically significant relative risks, number needed to harm were calculated. RESULTS: We retrieved six out of 17 eligible papers encompassing 3385 patients. Only hypertension (relative risk 2.98 95% confidence interval 2.32-3.84), gastrointestinal perforations (relative risk 5.04 95% confidence interval 1.72-14.79) and bleeding (relative risk 2.07 95% confidence interval 1.19-3.62) were significantly increased. Bevacizumab significantly improved both overall survival (HR 0.80 95% confidence interval 0.71-0.91) and progression-free survival (hazard ratio (HR) 0.62 95% confidence interval 0.52-0.74). Number needed to treat for overall survival is 12, whilst number needed to harms ranges from 2 to 14.286. CONCLUSION: These results show that the benefits of the treatment with bevacizumab outweigh the toxicity that may occur: enough to justify its use in advanced colorectal cancer.
