AIMS & METHODS: To analyse trends in the number of suspected UGI and LGI cancer referrals for all London Acute NHS Hospital Trusts (AHT) between 2004-2005.
Data for suspected UGI and LGI cancer referrals seen during the quarter for each AHT in the
London area was compared.
Names of London AHTs were obtained from the NHS website. AHTs were into their previous respective Strategic Health Authority (SHAs)localities. Resident population estimates (2004 mid-year estimates) for the 5 former London SHAs were based on the ONS National Population Census 2001. Summary statistics were calculated.

RESULTS: There were 109,536 UGI and 182,479 LGI suspected cancer referrals for over 2004-2005, of which 8,900 UGI and 18,757 LGI suspected cancer referrals were from
London . Significant variation was seen in the numbers of suspected UGI Cancer Referrals in each SHA (ratio between lowest (NWL) and highest (NEL) being 3.3). Significant variation was seen in the number of suspected LGI Cancer Referrals in each SHA (ratio between lowest (NWL) and highest (NEL) being 2.3). London has significantly lower rates of Suspected UGI (0.12%) and LGI Cancer Referrals (0.25%) than
(UGI 0.22%, LGI 0.37%)(p=0.00001). Population adjusted referral rates ranked NEL, SEL, SWL, NCL, and NWL highest to lowest for suspected UGI cancer referrals and SEL, NEL, SWL, NWL, and NCL highest to lowest for suspected LGI cancer referrrals. London suspected UGI/LGI cancer referrals accounted for 8%/10% of all
referrals respectively. Moreover essentially equal levels of deprivation existed in all 5 former SHAs.
CONCLUSION: In summary, marked variation exists in the number of suspected UGI and lower GI cancer referrals amongst the 5 former SHAs in London
.
