Neoadjuvant Therapy in Early Breast Cancer: Treatment Considerations and Common Debates in Practice.

Neoadjuvant treatment offers a number of benefits for patients with early breast cancer, and is an important option for consideration by multidisciplinary teams. Despite literature showing its efficacy, the use of neoadjuvant therapy varies widely. Here we discuss the clinical evidence supporting the use of neoadjuvant therapy in early stage breast cancer, including patient selection, monitoring response, surgery and radiotherapy considerations, with the aim of assisting multidisciplinary teams to determine patient suitability for neoadjuvant treatment.

Laparoscopic biliary injury: more than a learning curve problem.

BACKGROUND: The increase in the incidence of iatrogenic injury to the extrahepatic biliary tree that has been documented since the introduction of laparoscopic cholecystectomy (LC) has been explained as a 'learning curve' problem. The early New Zealand experience has been published and the present study was undertaken to determine whether there had been any change in the incidence, nature and management of laparoscopic biliary injuries (LBI) after further experience with LC. METHODS: A nationwide audit was undertaken in 1995 by two confidential postal questionnaires: to all active general surgeons (n=184, response rate 60%), and to all endoscopists performing endoscopic retrograde cholangiopancreatography (ERCP) (n=18, response rate 100%). RESULTS: The total number of LBI was 21, compared with 41 for 1991-92. The site and nature of the injuries were similar for the two survey periods. More of the injuries appeared to be diagnosed after the operation and prior to discharge (25% vs 47%). Calculating the national incidence of LBI was not possible without complete reporting, but in the subset of surgeons responsible for the LBI there was no apparent decrease in the incidence of all LBI (2.8% vs 2.9%), those requiring active re-intervention (2.4% vs 2.7%) and major duct injury (1.1% vs 0.7%), despite a significant increase in the surgeons' prior experience with LC (20% vs 61% of surgeons had performed more than 100 LC). There were some concerning trends in management: a less frequent use of ERCP in patients with LBI diagnosed after surgery (76% vs 65%) and a higher proportion of patients with minor injuries managed by re-operation (26% vs 50%). CONCLUSIONS: The present study indicates that iatrogenic biliary injury is a persistent problem in New Zealand, despite increasing experience with LC, and suggests the need for more intensive scrutiny of operative technique and training. There is scope to manage more patients with minor duct injuries conservatively.
