Table 3 Tumour content ratio and cobas sensitivity

From: Tumour content ratio matters for detecting epidermal growth factor receptor mutation by cobas test in small biopsies; a retrospective study

 

Tumour content ratio

<  10%

Tumour content ratio

≥ 10%

EGFR positive samples with cobas/total samples, n (%)

17/32 (53)

83/100 (83)

EGFR positive samples after dissection/total number of dissected samples, n (%)

5/15 (33)

2/14a (14)

  1. Abbreviations: EGFR epidermal growth factor receptor
  2. aThree of the EGFR negative samples were not included due to an inadequate amount of tissue for cobas retesting
