Tumour morphology by CA125 test result
| n | Borderline tumour, n (%) | Invasive tumour | Overall analysis, P-value | |||
|---|---|---|---|---|---|---|
| Epithelial, n (%) | Non-epithelial, n (%) | NOS, n (%) | ||||
| Abnormal CA125 test result | 351 | 47 (13) | 284a (81) | 4 (1) | 16 (5) | <0.001 |
| Normal CA125 test result | 105 | 51 (49) | 39b (37) | 9 (9) | 6 (6) | — |

a
Serous, n = 158; endometrioid, n = 16; mucinous, n = 14; clear cell, n = 14; other epithelial, n = 13; epithelial cancers of unknown morphology, n = 69.
b
Serous, n = 16; endometrioid, n = 4; mucinous, n = 8; clear cell, n = 3, other epithelial, n = 4; epithelial cancers of unknown morphology, n = 4. P-values are derived from Fisher’s exact test for independence. CA125 = cancer antigen 125. NOS = not otherwise specified, that is, could not be classified as epithelial or non-epithelial based on the information in the cancer registry.
