Abstract
Purpose
From 2011 to 2013 in the area of the Naples 3 public health district (ASL-NA3), a colorectal cancer screening program (CCSP) was developed. In order to stress the need of quality assurance procedures for surgery and pathology, a third level oncologic pathway was added and set up at a referral colorectal cancer center (RC). Lymph nodal (LN) harvesting, as a process indicator, and nodal positivity were adopted for an interim analysis.
Methods
The program was implemented by a series of audit meetings and a double type of multidisciplinary team (MDT): “horizontal” and “vertical.” Three hundred and forty colorectal cancer (CRC) patients underwent surgery: 119 chose to be operated at the RC (Gr In), 65 were operated at 22 district hospitals (DH) (Gr Out), and 156 symptomatic not screened patients were operated at the RC (Gr Sym).
Results
Statistical analysis revealed differences between Gr In and Gr Out colon groups both for LN harvesting (median of 26 and 11, respectively, P = 0.0001), and for nodal positivity after the first screening round (34.78 and 19.45 %, respectively, P = 0.0169). Results were all the more significant in a subset analysis on early T stage colon subgroups (In vs Out) both for LN harvesting (P < 0.0001) and nodal positivity (P < 0.0001).
Conclusion
xSignificant differences between RC and DHs were found, particularly for early-stage CRC patients. LN harvesting should be considered as a surrogate marker of quality assurance for at least screening hospitals for “minimum best” standard of care. This should lead to set up a third level in any CCSP.
