A uterine corpus tumour extends into the parametrium. Should it be classified as T2 or T3a?
T3a. T2 tumours invade the cervix but do not extend beyond the uterus. 2.9.2 A radical hysterectomy specimen shows an adenocarcinoma penetrating the serosal surface (pT3a) of the corpus uteri. All regional lymph nodes were negative, but there was metastatic adenocarcinoma in parametrial soft tissue. Does this change the stage of the tumour? T3a includes “discontinuous involvement of adnexa and serosa within the pelvis”. 2.10 Ovary versus uterus 2.10.1 A patient has a high grade (serous and clear cell) carcinoma confined to endometrium with peritoneal implants including surface of both ovaries, a small focus in one ovary and a large omental cake. Should we stage this as an ovarian tumour (M0) or an endometrial tumour (M1)? It would be very unusual for a superficial endometrial primary to produce an omental mass. Most would treat this as a primary ovarian lesion with a superficial second primary in the endometrium, making it a Stage IIIC ovarian with a Stage IA endometrial tumour. 2.11 O
