To evaluate the relative efficacy and safety of anti-vascular endothelial growth factor (anti-VEGF) agents for the treatment of neovascular age-related macular degeneration (AMD). Systematic literature review identifying RCTs comparing anti-VEGF agents to another treatment published before June 2016. Efficacy assessed by mean change in best corrected visual acuity (BCVA) and central macular thickness (CMT) from baseline at up to 2 years followup. Safety assessed by proportions of patients with death, arteriothrombotic and venous thrombotic events, and at least one serious systemic adverse event at up to 2 years of followup. Fifteen RCTs selected for meta-analysis (8320 patients). Two trials compared pegaptanib, and three trials compared ranibizumab versus control. Eight trials compared bevacizumab with ranibizumab. Two trials compared aflibercept with ranibizumab. There were no significant differences between bevacizumab and ranibizumab for BCVA at 1 or 2 years (weighted mean difference = − 0.57, 95% CI − 1.55 to 0.41, P = 0.25 and weighted mean difference = − 0.76, 95% CI − 2.25 to 0.73, P = 0.32, respectively). Ranibizumab was more effective in reducing CMT at 1 year (weighted mean difference = 4.49, 95% CI 1.13 to 7.84, P = 0.009). Risk ratios comparing rates of serious systemic adverse events at 1 and 2 years were slightly out of favour for bevacizumab. Aflibercept compared with ranibizumab demonstrated similar mean change in BCVA, reduction in CMT, and safety at 1 year. Bevacizumab and ranibizumab had equivalent efficacy for BCVA, while ranibizumab had greater reduction in CMT and less rate of serious systemic adverse events. Aflibercept and ranibizumab had comparable efficacy for BCVA and CMT. This provides information to balance comparable effects on vision and risk of adverse events between anti-VEGF agents.

Background: The methods for sentinel lymph node (SLN) biopsy in breast cancer have been variable in type and number of tracers. Some units have abandoned the use of blue dye (BD) due to adverse reactions. Fluorescence-guided biopsy with indocyanine green (ICG) is a relatively novel technique. This study compared the clinical efficacy and costs between novel dual tracer ICG and radioisotope (ICG-RI) with “gold standard” BD and radioisotope (BD-RI). Methods: Single-surgeon study of 150 prospective patients with early breast cancer undergoing SLN biopsy (2021-2022) using ICG-RI compared with a retrospective cohort of 150 consecutive previous patients using BD-RI. Number of SLNs identified, rate of failed mapping, identification of metastatic SLNs, and adverse reactions were compared between techniques. Cost-minimisation analysis performed by using Medicare item numbers and micro-costing analysis. Results: Total number of SLNs identified with ICG-RI and BD-RI was 351 and 315, respectively. Mean number of SLNs identified with ICG-RI and BD-RI was 2.3 (standard deviation [SD] 1.4) and 2.1 (SD 1.1), respectively (p = 0.156). There were no cases of failed mapping with either dual technique. Metastatic SLNs were identified in 38 (25.3%) ICG-RI patients compared with 30 (20%) BD-RI patients (p = 0.641). There were no adverse reactions to ICG, whereas four cases of skin tattooing and anaphylaxis were associated with BD (p = 0.131). ICG-RI cost an additional AU$197.38 per case in addition to the initial cost for the imaging system. Clinical trial registration: ACTRN12621001033831. Conclusions: Novel tracer combination, ICG-RI, provided an effective and safe alternative to “gold standard” dual tracer. The caveat was the significantly greater costs associated with ICG.

Background Repair of giant paraesophageal hernia (PEH) is associated with a considerable hernia recurrence rate by objective measures. This study analyzed a large series of laparoscopic giant PEH repair to determine factors associated with anatomical recurrence. Method Data was extracted from a single-surgeon prospective database of laparoscopic repair of giant PEH from 1991 to 2021. Upper endoscopy was performed within 12 months postoperatively and selectively thereafter. Any supra-diaphragmatic stomach was defined as anatomical recurrence. Patient and hernia characteristics and technical operative factors, including “composite repair” (360° fundoplication with esophagopexy and cardiopexy to right crus), were evaluated with univariate and multivariate analysis. Results Laparoscopic primary repair was performed in 862 patients. The anatomical recurrence rate was 27.3% with median follow-up of 33 months (IQR 16, 68). Recurrence was symptomatic in 45% of cases and 29% of these underwent a revision operation. Hernia recurrence was associated with younger age, adversely affected quality of life, and were associated with non-composite repair. Multivariate analysis identified age < 70 years, presence of Barrett’s esophagus, absence of “composite repair”, and hiatus closure under tension as independent factors associated with recurrence (HR 1.27, 95%CI 0.88–1.82, p = 0.01; HR 1.58, 95%CI 1.12–2.23, p = 0.009; HR 1.72, 95%CI 1.2–2.44, p = 0.002; HR 2.05, 95%CI 1.33–3.17, p = 0.001, respectively). Conclusion Repair of giant PEH is associated with substantial anatomical recurrence associated with patient and technique factors. Patient factors included age < 70 years, Barrett’s esophagus, and hiatus tension. “Composite repair” was associated with lower recurrence rate.

Background: Offering breast reconstruction (BR) at the time of mastectomy is standard of care in Australia with proven quality‐of‐life benefits. Previously BR rates in Australia have been low compared to similar countries. Accurate up‐to‐date information is needed to promote equity in access to BR and inform future planning of services. This study analysed recent trends and variations of BR uptake in Australia.Method: Data from the BreastSurgANZ Quality Audit (BQA) were used to identify patients who underwent mastectomy with or without reconstruction for invasive or in situ breast carcinoma from 2010 to 2019. The association between BR uptake and the variables of jurisdiction (state or territory), age, hospital type and remoteness, and remoteness of patients' home addresses were analysed.Results: A total 41 880 women underwent mastectomy between 2010 to 2019. The national BR rate steadily increased from 12.8% in 2010 to 29% in 2019, with a 10‐year national average of 21.3%. Statistically significant differences in BR uptake (P < 0.001) were found between states with higher rates in New South Wales and Victoria, with BR more likely in private hospitals and in younger women (P < 0.001), and less likely in remote areas (P < 0.001).Conclusion: The Australian BR rate has increased over the 10‐year period, but significant variation still exists between states. BR is lower in older women and those living in regional and remote areas. While the steady increase in BR uptake is encouraging, barriers that exist to equitable provision of reconstructive surgical services for all women living with breast cancer still need to be corrected.

Background: Wire localisation (WL) is the “gold standard” localisation technique for wide local excision (WLE) of non-palpable breast lesions but has disadvantages that have led to the development of wireless techniques. This study compared the cost-effectiveness of radar localisation (RL) to WL. Methods: This was a single-institution study of 110 prospective patients with early-stage breast cancer undergoing WLE using RL with the SCOUT^® Surgical Guidance System (2021–2023) compared with a cohort of 110 patients using WL. Margin status, re-excision rates, and surgery delays associated with preoperative localisation were compared. Costs from a third-party payer perspective in Australian dollars (AUD$) calculated by using microcosting, break-even point, and cost-utility analyses. Results: A total of 110 WLEs using RL cost a total of AUD$402,281, in addition to the device cost of AUD$77,150. The average additional cost of a surgery delay was AUD$2318. Use of RL reduced the surgery delay rate by 10% (p = 0.029), preventing 11 delays with cost savings of AUD$25,496. No differences were identified in positive margin rates (RL: 11.8% vs. WL: 17.3%, p = 0.25) or re-excision rates (RL: 14.5% vs. WL: 21.8%, p = 0.221). In total, 290 RL cases are needed to break even. The cost of WLE using RL was greater than WL by AUD$567. There was a greater clinical benefit of 1.15 quality-adjusted life-years (QALYs) and an incremental cost-utility ratio of AUD$493 per QALY favouring RL. Conclusions: Routine use of RL was a more cost-effective intervention than WL. Close to 300 RL cases are likely needed to be performed to recover costs of the medical device.
