ABSTRACT

AIM: To evaluate the impact of the national 'Be Clear on Cancer' bowel cancer reminder campaign on service and diagnosis at a single UK institution. Secondly, to evaluate the socio-economic background of patients referred before and after the reminder campaign compared with the regional demographic. METHOD: Suspected cancer 2-week wait patients in the 3 months precampaign, postcampaign and after the reminder campaign were included. Demographics, investigations and diagnosis were recorded. The postcode was used to allocate a National Readership Survey social grade. RESULTS: Three hundred and eighty-three referrals were received in the 3 months precampaign, 550 postcampaign and 470 postreminder campaign. There were significant increases in the monthly referral rates following the campaign (P < 0.001 in both the post- and postreminder periods). Significantly more patients from social grades AB and C1C2 than expected from regional demographics were referred precampaign and after the reminder campaign (P < 0.001 in each case). There were no significant differences between the proportions of patients diagnosed with colorectal cancer in the three study periods (P = 0.710). CONCLUSION: The 'Be Clear on Cancer' bowel cancer campaign has had a significant sustained impact on resources. It has failed to increase referrals among lower socio-economic grades, leading to an increase in 'worried well' referrals and no change in numbers, or the stage, of colorectal cancers diagnosed.

ABSTRACT

BACKGROUND: Extra-levator abdominoperineal excision of the rectum (ELAPER) for low rectal cancer is used to avoid the adverse oncological outcomes of inadvertent perforation and a positive circumferential resection margin associated with the conventional APER technique. This wider excision creates a large defect requiring pelvic floor reconstruction, and there is still controversy regarding the best method of closure. The aim of this study is to present outcomes of biological mesh pelvic floor reconstruction following ELAPER. METHODS: Prospective data on consecutive patients having ELAPER for low rectal cancer at a single UK institution between October 2008 and March 2013 were collected. The perineum was reconstructed using a biological mesh and the short-term outcomes were evaluated, focusing particularly on perineal wound complications and perineal hernias. RESULTS: Thirty-four patients were included [median age 62 years, range 40-72 years, 27 males (79 %)]. The median operative time was 248 min (range 120-340 min). The median length of hospital stay was 9 days (range 4-20 days). There were three perineal complications (9 %) requiring surgical intervention, but no meshes were removed. There were no perineal hernias. The median length of follow-up was 21 months (range 1-54 months). The overall mortality was 9 % from distant metastases. CONCLUSIONS: Our series adds to the increasing evidence that good outcomes can be achieved for pelvic floor reconstruction with biological mesh following ELAPER without the additional use of myocutaneous flaps. The low serious complication rate, good outcomes in perineal wound healing and the absence of perineal hernias demonstrates that this is a safe and feasible procedure.

ABSTRACT

AIM: A literature review was performed to elucidate whether long-course preoperative radiotherapy for patients with rectal cancer affects lymph node yield, and whether this influences prognosis. METHOD: Cochrane Database, PubMed/MEDLINE, Scopus, Web of Knowledge, Embase and CINAHL databases and reference lists from published journal articles published between 1 January 1990 and 30 June 2011 were searched. Studies examining lymph node yield and prognosis were selected for review. RESULTS: One thousand and twenty-nine articles were found, of which 11 met the inclusion criteria. None was a randomized controlled trial and all were cohort studies. Four studies showed that long-course preoperative radiotherapy reduced lymph node yield; however only one demonstrated a statistically significant survival benefit in patients with higher lymph node yields. Five-year survival was 48% in patients with fewer than and 69% in those with more than 11 lymph nodes identified in the operative specimen (P = 0.04). CONCLUSION: Whilst long-course preoperative radiotherapy appears to reduce lymph node yield in patients with rectal cancer, no causal relationship between lymph node yield and survival can be established in this group of patients.

ABSTRACT

Micro-satellite instability (MSI) is relevant in the management of colorectal cancers (CRC) and relies on analysis of gene mutations, or production of the proteins involved in DNA mismatch repair (e.g. MLH1, MSH2). p53 mutation is also relevant in MSI, but high-level CRC (MSI-H) demonstrate fewer mutations than low-level (MSI-L) or stable (MSS) cancers. Recently, the importance of gene activity (transcription) in MSI has been identified, where rather than being mutated genes have been downregulated. In this study, 67 sporadic CRC and eight samples of normal bowel were analysed for MSI status (by SSCP) and levels of MLH1, MSH2 and p53 gene transcription (by RT-PCR and scanning densitometry). Micro-satellite instability correlated with gender and site, with more MSI-H CRC in females (P<0.02) and in the right colon (P<0.04). In MSI-H, p53 transcription was markedly reduced (P<0.003). Compared to normal bowel, MLH1 transcription was elevated in all cancers (P<0.01), while MSH2 transcription was elevated only in MSI-H (P<0.04). There was a direct correlation between MLH1 and MSH2 transcription (P<0.001). Although fewer mutations are reported in MSI-H than MSI-L/MSS, these results suggest that reduced p53 transcription might account for decreased tumour suppression in MSI-H. The direct correlation between MLH1 and MSH2 transcription suggests that control of these genes might be coordinated.
