Accurate digital rectal examination (DRE) enables the early diagnosis of palpable rectal tumour. We aimed at evaluating the diagnostic value of DRE performed by general practitioners (GPs), with respect to detecting the presence of a palpable rectal tumour. ⋯ Digital rectal examination in primary care for palpable rectal tumour has a sensitivity of 0.762, specificity of 0.917, positive predictive value of 0.296 and negative predictive value of 0.988. It is an inaccurate procedure and a poor predictor for palpable rectal tumour.
