Hyperplastic polyposis syndrome and the risk of colorectal cancer: Table 1

I read with great interest the two reports by Boparai and coworkers in Gut on the increased risk of colorectal carcinoma (CRC) in 77 hyperplastic/serrated polyposis syndrome (HPS) patients during follow-up1 and in 347 HPS first-degree relatives (FDRs).2 To date, follow-ups have been performed in only 43/308 (14.0%) HPS patients and HPS coexistence with CRC in FDRs has been analysed in only 29/308 (9.4%) HPS patients described up to the end of 2009 (table 1).
