ABSTRACT

BACKGROUND: Oncological outcomes of laparoscopic colon cancer surgery have been shown to be equivalent to those of open surgery, but only in the setting of randomized controlled trials on highly selected patients. The aim of this study is to investigate whether this finding is generalizable to real world practice. METHODS: Analysis of prospectively collected data from the BioGrid Australia database was undertaken. Overall and cancer specific survival rates were compared with cox regression analysis controlling for the confounders of age, sex, BMI, ASA score, hospital site, year surgery performed, procedure, tumor stage, and adjuvant chemotherapy. RESULTS: Between 2003 and 2009, 1,106 patients underwent elective colon cancer resection. There were differences between the laparoscopic and open cohorts in BMI, procedure, post-operative complication rate, and tumor stage. When baseline confounders were accounted for using cox regression analysis, there was no difference in 5 year overall survival (χ(2) test 1.302, P = 0.254), or cancer specific survival (χ(2) test 0.028, P = 0.866). CONCLUSION: This large prospective clinical study validates previous trial results, and confirms that there is no difference in oncological outcome between laparoscopic and open surgery for colon cancer.

ABSTRACT

AIM: To review the preliminary results of the ligation of the intersphincteric fistula tract (LIFT) technique in treating complex anal fistulas at our hospital. METHOD: Between March and November 2010, patients with cryptoglandular anal fistulas were recruited prospectively from the colorectal clinic and treated using the LIFT procedure. A database was set up to collect information on demographics, past surgical treatments, fistula characteristics, MRI scan results, operative data and follow-up findings. The primary end-point measured was cure of the disease. The secondary end-point was the degree of postoperative continence. Preoperative and postoperative incontinence rates were recorded using Wexner's Incontinence Scale. RESULTS: Twenty-five patients (eight women and 17 men; median age, 40 years) underwent the LIFT procedure. Ten patients had recurrent fistulas and previous fistula surgery. The median operating time was 39 min. No intraoperative complications were documented. The median follow-up duration was 22 (3-43) weeks. Primary healing was observed in 17 (68.0%) patients and the median healing time was 6 weeks; one wound remained incompletely healed. Seven patients (28.0%) had disease recurrence presenting between 7 and 20 weeks postoperatively. No patients reported any incontinence postoperatively. CONCLUSION: The LIFT procedure has favourable healing rates with little or no risk of incontinence. This operation is safe and easy to learn. The early results from this pilot study show promise and affirm some of the findings of other researchers. These results will suggest opportunities to conduct further controlled studies comparing the LIFT procedure with standard therapies.

ABSTRACT

BACKGROUND/AIM: The complexity and cost of treating cancer patients is escalating rapidly and increasingly difficult decisions are being made regarding which interventions provide value for money. BioGrid Australia supports collection and analysis of comprehensive treatment and outcome data across multiple sites. Here, we use preliminary data regarding the National Bowel Cancer Screening Program (NBCSP) and stage-specific treatment costs for colorectal cancer (CRC) to demonstrate the potential value of real world data for cost-effectiveness analyses (CEA). METHODS: Data regarding the impact of NBCSP on stage at diagnosis were combined with stage-specific CRC treatment costs and existing literature. An incremental CEA was undertaken from a government healthcare perspective, comparing NBCSP with no screening. The 2008 invited population (n= 681,915) was modelled in both scenarios. Effectiveness was expressed as CRC-related life years saved (LYS). Costs and benefits were discounted at 3% per annum. RESULTS: Over the lifetime and relative to no screening, NBCSP was predicted to save 1265 life years, prevent 225 CRC cases and cost an additional $48.3 million, equivalent to a cost-effectiveness ratio of $38,217 per LYS. A scenario analysis assuming full participation improved this to $23,395. CONCLUSIONS: This preliminary CEA based largely on contemporary real world data suggests population-based faecal occult blood test screening for CRC is attractive. Planned ongoing data collection will enable repeated analyses over time, using the same methodology in the same patient populations, permitting an accurate analysis of the impact of new therapies and changing practice. Similar CEA using real world data related to other disease types and interventions appears desirable.

ABSTRACT

BACKGROUND: Varying amounts of data related to cancer diagnosis, treatment and/or outcome are routinely collected by many disparate groups. Routinely combining data from these sources could improve data quality and utility for audit and research purposes. The aim of this study is to demonstrate the benefits of linkage between oncology databases. METHODS: We examined colorectal cancer (CRC) data recorded by the Victorian Cancer Registry and two hospital clinical databases between January 2000 and December 2005. Where data were in common, the completeness and accuracy of each dataset were examined. Where content differed, the potential value of making this additional data available to the other database was examined. RESULTS: Of the 831 cases recorded at the hospitals, 822 (98.9%) were also recorded on the cancer registry. Eight of the 913 cases (0.87%) recorded as having CRC by the registry did not have CRC. Errors in recording of tumour site and tumour or nodal stage were frequent in both databases. Metastasis stage was recorded in only 29 of 822 (3.5%) registry cases examined. Discordance for diagnosis date and death date was also frequent, although the difference was typically minor. Adding additional death data from the registry to the clinical database significantly altered stage-specific and overall survival figures. CONCLUSION: A multidirectional flow of data between hospital and registry databases provides multiple opportunities to improve data quality and utility. While issues around data ownership and usage need to be considered, the advantages of routine data linkage are readily apparent.
