Routine clinical practice data often differ from clinical trials. This study describes real-world treatment patterns and effectiveness among patients with metastatic colorectal cancer (mCRC) receiving ziv-aflibercept in non-academic, community oncology practices in the USA. De-identified electronic medical records from Vector Oncology and Altos Solutions databases were analysed. We identified 218 patients diagnosed with mCRC who had received prior oxaliplatin therapy and initiated ziv-aflibercept as part of second-line or later-line therapy. Overall survival (OS) and progression-free survival (PFS) were estimated using Kaplan-Meier analysis. Mean age was 62.8 years at ziv-aflibercept initiation. Most patients (91.7%) received bevacizumab before ziv-aflibercept, 95.4% initiated ziv-aflibercept with FOLFIRI or another irinotecan-based regimen, and 59.6% had received prior irinotecan. Overall, 24.8% of patients initiated ziv-aflibercept in second line, 31.7% in third line, 21.6% in fourth line and 22.0% in later lines of therapy. Mean duration of ziv-aflibercept treatment was 5.3 months. For patients initiating ziv-aflibercept in second-, third- and fourth-line therapy, median OS was 11.9 (95% confidence interval 5.1-16.2), 11.1 (6.9-16.7) and 8.1 (5.2-11.4) months, respectively, and median PFS was 4.4 (2.8-6.5), 4.3 (2.9-6.3) and 3.4 (2.2-5.2) months, respectively. Common adverse events (AEs) (any grade) included gastrointestinal disorders (64.7%) and asthenia/fatigue (63.3%). In routine clinical practice, ziv-aflibercept was frequently initiated in third line or later lines of therapy. Although patients receiving ziv-aflibercept were more heavily pretreated and potentially less robust compared with the VELOUR trial, median OS for patients receiving second-line ziv-aflibercept was comparable. AE rates were similar to or lower than the VELOUR trial. [ABSTRACT FROM AUTHOR]

It is unclear how treatment sequencing for metastatic castration-resistant prostate cancer (mCRPC) affects real-world patient outcomes. We assessed treatment sequences, patient characteristics and overall survival (OS) in post-docetaxel mCRPC patients. mCRPC patients receiving second-line cabazitaxel or androgen receptor-targeted therapy (ART; abiraterone/enzalutamide) post-docetaxel were identified using electronic medical records. OS was assessed from second-line therapy initiation using Cox regressions adjusting for: metastases; prostate-specific antigen (PSA); hemoglobin; alkaline phosphatase (ALP); albumin; second-line therapy initiation year. Following docetaxel (n = 629), 123 (19.6%) and 506 (80.4%) patients received cabazitaxel and ART, respectively. One hundred and ninety-five patients received additional treatments thereafter (54 following cabazitaxel; 141 following ART). Although patients receiving second-line cabazitaxel versus ART had similar disease characteristics at first-line therapy initiation, at second-line therapy initiation they had higher mean PSA (386.6 vs. 233.9 ng/mL) and ALP (182.0 vs. 167.3 u/L), lower mean hemoglobin (10.8 vs. 11.5 g/dL), and more frequently had intermediate/high-risk Halabi scores (61.8 vs. 48.4%); all p < 0.05. Overall, crude survival was not significantly different. Among Halabi high-risk patients, adjusted median OS was significantly longer in patients receiving cabazitaxel versus ART (HR 0.48; 95% CI 0.24-0.93; p = 0.030). Low albumin and hemoglobin led to similar findings (HR 0.43; 95% CI 0.23-0.80; p = 0.0077; HR 0.60; 95% CI 0.40-0.90; p = 0.014). Most post-docetaxel patients received second-line ART. Patients receiving second-line cabazitaxel had more high-risk features; however, second-line cabazitaxel administered after docetaxel may improve OS in patients with Halabi high-risk scores or low albumin/hemoglobin.

Constipation is a prevalent condition that disproportionately affects women and older adults and leads to self-medication and/or medical consultation. It occurs as a result of functional idiopathic causes or secondarily as a result of a variety of factors including dietary and exercise patterns, adverse effects of medication and disease processes. Constipation is often perceived to be a benign, easily treated condition with short-term treatment being relatively straightforward; however, chronic constipation is associated with mild complications that, left untreated, can develop into more serious bowel complaints (faecal impaction, incontinence and bowel perforations) with further implications for healthcare costs and the patient's health-related quality of life (HR-QOL). This review summarises the evidence of the HR-QOL impact and economic burden of constipation on patients. Relatively few studies have systematically explored the HR-QOL and economic impact of constipation; however, the existing evidence suggests that HR-QOL is lower in patients with constipation than in non-constipated individuals, and treatments for constipation improve HR-QOL. Additionally, constipation represents an economic burden for the patient and healthcare provider. Resource utilisation associated with the diagnosis and management of constipation is a significant cost driver, whereas constipation prevention programmes have demonstrated cost savings.
