The cohort of ovary, fallopian tube and primary peritoneal carcinomas used for this Ovarian Cancer Audit Feasibility Pilot is all tumours coded in ICD-10 and ICD-O-2 to:
C56 (Malignant neoplasm of ovary)
C57 (Malignant neoplasm of other and unspecified female genital organs)
C48 (Malignant neoplasm of retroperitoneum and peritoneum), excluding sarcomas: 8693, 8800, 8801, 8802, 8803, 8804, 8805, 8806, 8963, 8990, 8991, 9040, 9041, 9042, 9043, 9044, 8810, 8811 – 8921, 9120 – 9373, 9490, 9500, 9530 – 9582
D39.1 (Neoplasm of uncertain or unknown behaviour of ovary)
Only female patients are included in the cohort.
This definition aligns with international ovarian cancer analyses and is designed to capture all ovarian cancers; although there may be variation in the coding of the originating site within this group, in practice their prognosis and treatment are similar. The inclusion of D39.1 means that the cohort includes all ‘borderline malignant’ ovarian cancer.
