Endocervical curettage for diagnosing high-grade squamous intraepithelial lesions or worse in women with type 3 transformation zone lesions: a retrospective, observational study

Table 2 The performance of ECC and biopsy for detecting HSIL+

Histopathology diagnosis by ECC	Biopsy Histopathology diagnosis
Histopathology diagnosis by ECC	<HSIL	HSIL+	Total
<HSIL	1514 (79.5%)	234 (12.3%)	1748 (91.8%)
HSIL+	15 (0.8%)	142 (7.4%)	157 (8.2%)
Total	1529 (80.3%)	376 (19.7%)	1905 (100%)
	^aHSIL+ diagnostic yield by biopsy 234/1905 = 12.3% ^bHSIL+ diagnostic yield by both biopsy and ECC 142/10905 = 7.4% ^cHSIL+ diagnostic yield by ECC 15/1905 = 0.8% ^dHSIL+ diagnostic yield totally (376 + 157–142) /1905 = 20.5%

Abbreviation: ECC endocervical curettage, <HSIL included normal and LSIL HSIL+ included HSIL and invasive cancers
^aHSIL+ diagnostic yield by biopsy: HSIL+ cases that would have been detected by biopsy but missed by ECC alone
^bHSIL+ diagnostic yield by both biopsy and ECC: Cases that ECC and biopsy results are HSIL+
^cHSIL+ diagnostic yield by ECC: HSIL+ cases that would have been detected by ECC but missed by biopsy alone
^dHSIL+ diagnostic yield totally: HSIL+ cases that would have been detected by ECC and biopsy
