Survival outcome of patients with screening versus symptomatically detected colorectal cancers.

AIM: The national Bowel Cancer Screening Programme has been rolled out nationwide following pilot screening in two health authorities in the UK. The aim of this study was to define overall 5-year survival of screen detected cancers and to compare the overall survival outcome of screened vs symptomatic patients over a 10-year period. METHOD: All patients with colorectal cancer treated at one trust in patients of screening age (50-69 years) during the pilot screening programme (2000-2008) were analysed. Patients were defined as screen detected or symptomatically detected. Disease pathology and recurrence data were obtained from the hospital's computerized results reporting system and mortality was cross-matched with data from the West Midlands Cancer Intelligence Network. RESULTS: In all, 633 patients aged 50-69 were identified in the study period; 155 patients had a screen detected cancer and 478 did not. A log-rank test completed on survival outcomes indicated that survival was significantly worse in the symptomatic group. This difference persisted if only patients treated with curative intent were considered. CONCLUSION: Survival outcome was significantly better in the screened vs the symptomatic population in all groups and also in those treated for curative intent. There was a trend towards better survival for screen detected cancer when compared stage for stage.

Rectal cancer: involved circumferential resection margin - a root cause analysis.

INTRODUCTION: An involved circumferential resection margin (CRM) following surgery for rectal cancer is the strongest predictor of local recurrence and may represent a failure of the multidisciplinary team (MDT) process. AIM OF STUDY: The study analyses the causes of positive CRM in patients undergoing elective surgery for rectal cancer with respect to the decision-making process of the MDT, preoperative rectal cancer staging and surgical technique. METHOD: From March 2002 to September 2005, data were collected prospectively on all patients undergoing elective rectal cancer surgery with curative intent. The data on all patients identified with positive CRM were analysed. RESULTS: Of 158 patients (male:female = 2.2:1) who underwent potentially curative surgery, 16 (10%) patients had a positive CRM on postoperative histology. Four were due to failure of the pelvic magnetic resonance imaging (MRI) staging scans to predict an involved margin, two with an equivocal CRM on MRI did not have preoperative radiotherapy, one had an inaccurate assessment of the site of primary tumour and in one intra-operative difficulty was encountered. No failure of staging or surgery was identified in the remaining eight of the 16 patients. Abdominoperineal resection (APR) was associated with a 26% positive CRM, compared with 5% for anterior resection. CONCLUSION: No single consistent cause was found for a positive CRM. The current MDT process and/or surgical technique may be inadequate for low rectal tumours requiring APR.

Transanal endoscopic microsurgery--lessons from a single UK centre series.

OBJECTIVES: Transanal endoscopic microsurgery (TEM), a minimally invasive technique has been employed in the excision of benign and selected malignant rectal tumours since 1983. We present a single surgeon's series of 102 procedures. PATIENTS AND METHODS: A retrospective case note review of 102 procedures performed over a 6-year period between 1996 and 2001. RESULTS: One hundred and two TEM procedures were performed on 100 patients. 68 for adenomas, 19 potentially curative excisions for carcinoma, 13 palliative procedures for advanced carcinoma and 2 for solitary rectal ulcer syndrome (SRUS). Four adenomas recurred and were successfully treated by various procedures. None went on to develop malignancy, or a further recurrence. Of the cancers, six T1 and 10 T2 were excised with curative intent. Three T3 cancers were excised before endorectal ultrasound was available in the unit and went on to have definitive procedures. One T1 and two T2 carcinomas were not completely histologically excised. These patients were offered definitive procedure and there have been no recurrences. 11 patients underwent palliative TEM procedures, 2 went on to have a recurrence of symptoms. Both underwent a successful second TEM procedure. CONCLUSIONS: Although longer term follow up is still required, TEM appears to be an effective method of excising benign tumours and T1 carcinomas of the rectum. The role of TEM in the treatment of T2 carcinomas is, as yet, unclear and needs further evaluation although the results of our series and others are encouraging.
