This real-world retrospective cohort study using Australian Pharmaceutical Benefits Scheme (PBS) 10% investigated changes in chronic lymphocytic leukemia (CLL) treatment by line of therapy, time-to-next-treatment, treatment duration, and overall survival (OS). Overall, 803 patients received their first PBS-reimbursed CLL medication between 1 January 2011 to 31 July 2021 (median age: 70 years; 64.6% male), 289 post-1 August 2020. In 2011, most first-line (1 L) prescribing was fludarabine, cyclophosphamide, and rituximab (FCR). By 2021, common 1L were chlorambucil ± CD20 (26.1%), Bruton Tyrosine Kinase inhibitor (BTKi) (26.1%), and CD20 monotherapy (23.9%). In 2011, relapsed/refractory (R/R) CLL treatment was CD20 monotherapy or FCR. By 2021, BTKi (57.7%) and venetoclax ± CD20 (26.1%) were most common. Compared to FCR, 1 L treatment duration (Hazard Ratio) was shorter for CD20 monotherapy (1.7) or chlorambucil ± CD20 (2.5). In R/R CLL, median duration was 24 (ibrutinib) and 19 months (venetoclax). Median OS was 127 months. CLLtreatment pattern shave greatly changed in Australia since the introduction of novel therapies.

AbsractThis paper examines the potential effect of Direct-to-Consumer (DTC) advertising on consumers' behavioral intentions in relation to a medical issue. Using an online experiment, 1295 people were randomized to two information conditions. One group watched an advertisement for a hypothetical cold sore medicine, while a second (control) group did not view the advertisement, before both groups answered questions on symptoms. The responses were analyzed based on group allocation and the respondents' experience with cold sores. Results indicate that those who viewed the advertisement were more likely to choose the product, and the advertisement had larger effects based on consumer experience.

Objectives: To investigate the incidence of advanced neoplasia (colorectal cancer or advanced adenoma) at surveillance colonoscopy following removal of non-advanced adenoma; to determine whether the time interval before surveillance colonoscopy influences the likelihood of advanced neoplasia., Design: Retrospective cohort study., Setting, Participants: Patients enrolled in a South Australian surveillance colonoscopy program with findings of non-advanced adenoma during 1999-2016 who subsequently underwent surveillance colonoscopy., Main Outcome Measures: Incidence of advanced neoplasia at follow-up surveillance colonoscopy., Results: Advanced neoplasia was detected in 169 of 965 eligible surveillance colonoscopies (18%) for 904 unique patients (median age, 62.0 years; interquartile range [IQR], 54.0-69.0 years), of whom 570 were men (59.1%). The median interval between the initial and surveillance procedures was 5.2 years (IQR, 4.4-6.0 years; range, 2.0-14 years). Factors associated with increased risk of advanced neoplasia at follow-up included age (per year: odds ratio [OR], 1.03; 95% CI, 1.01-1.05), prior history of adenoma (OR, 1.48; 95% CI, 1.01-2.15), two non-advanced adenomas identified at baseline procedure (v one: OR, 1.74; 95% CI, 1.18-2.57), and time to surveillance colonoscopy (OR, 1.21; 95% CI, 1.08-1.37). The estimated incidence of advanced neoplasia was 19% five years after non-advanced adenoma removal, and 30% at ten years., Conclusions: Increasing the surveillance colonoscopy interval beyond five years after removal of non-advanced adenoma increases the risk of detection of advanced neoplasia at follow-up colonoscopy., (© 2021 AMPCo Pty Ltd.)
