Mortality and cost of radiation therapy for oesophageal cancer according to hospital accreditation level: a nationwide population‐based study

This study examined and analysed the relationship between the cost‐effectiveness and outcome of radiotherapy for oesophageal cancer among hospitals with varying accreditation levels. We selected 428 oesophageal cancer patients from medical and non‐medical centres using the National Health Insurance Research Database, which is maintained by the Taiwanese National Health Research Institutes, and compared their medical expenditure and the outcome of their radiotherapy treatment. In this study cohort of patients with oesophageal cancer, 278 patients were treated in medical centres (mean age: 60.1 years) and 150 patients were treated in non‐medical centres (mean age: 62.0 years, P = 0.16). The medical centre group exhibited significantly lower medical expenses, mortality and risk of death compared with the non‐medical centre group (adjusted hazard ratio = 1.38, 95% confidence interval = 1.11–1.71). Our study determined that radiotherapy for oesophageal cancer costs significantly less, and medical centres had lower mortality rates than non‐medical centres. These findings could provide professional organisations and healthcare policy makers with essential information for allocation of resources.     

Timely follow‐up of positive cancer screening results: A systematic review and recommendations from the PROSPR Consortium

Timely follow‐up for positive cancer screening results remains suboptimal, and the evidence base to inform decisions on optimizing the timeliness of diagnostic testing is unclear. This systematic review evaluated published studies regarding time to follow‐up after a positive screening for breast, cervical, colorectal, and lung cancers. The quality of available evidence was very low or low across cancers, with potential attenuated or reversed associations from confounding by indication in most studies. Overall, evidence suggested that the risk for poorer cancer outcomes rises with longer wait times that vary within and across cancer types, which supports performing diagnostic testing as soon as feasible after the positive result, but evidence for specific time targets is limited. Within these limitations, we provide our opinion on cancer‐specific recommendations for times to follow‐up and how existing guidelines relate to the current evidence. Thresholds set should consider patient worry, potential for loss to follow‐up with prolonged wait times, and available resources. Research is needed to better guide the timeliness of diagnostic follow‐up, including considerations for patient preferences and existing barriers, while addressing methodological weaknesses. Research is also needed to identify effective interventions for reducing wait times for diagnostic testing, particularly in underserved or low‐resource settings.

A phase IB dose-finding trial of liposomal doxorubicin in combination with capecitabine in patients with pretreated metastatic breast cancer

Purpose

Anthracyclines and fluoropyrimidines are very active in breast cancer, while liposomal doxorubicin has low cardiotoxicity. We conducted a dose-finding study of the combination of liposomal doxorubicin and capecitabine in patients with pretreated metastatic breast cancer.

Patients and methods

Patients received liposomal doxorubicin 60 mg/m² on day 1 plus capecitabine 825 mg/m² bid (level 0) or 1,000 mg/m² bid (level 1) on days 1–14 of each 21-day cycle to establish the maximum tolerated dose (MTD) and cardiac safety.

Results

Nine patients were enrolled and a total of 52 courses were delivered (median 6 cycles per patient [range 4–7]). Grade 4 neutropenia occurred in 15% of cycles, with one episode of febrile neutropenia; most nonhematological toxicities were mild or moderate. No formal MTD was established, and the study was closed because two cardiac events were observed at dose level 1 and another at dose level 0 in patients pretreated with epirubicin ≥ 560 mg/m².

Conclusions

The recommended dose for phase II studies is liposomal doxorubicin 60 mg/m² on day 1 plus capecitabine 825 mg/m²/bid on days 1–14 of each 21-day cycle. Despite the lower cardiotoxicity of liposomal doxorubicin, the risk of cardiac damage persists in anthracycline-pretreated individuals and mandates close cardiac monitoring and careful evaluation of the overall cumulative dose.
