Stage IIIC2 includes: TX, T0, T1-3, N2, M0. TX: Primary tumor cannot be assessed. T0: No evidence of primary tumor. T1: Tumor strictly confined to the cervix (extension to corpus should be disregarded). T2: Tumor invading beyond the uterus but not to the pelvic wall or to lower third of vagina. T3: Tumor extending to pelvic sidewall and/or involving the lower third of vagina, and/or causing hydronephrosis or nonfunctioning kidney. The pelvic sidewall is defined as the muscle, fascia, neurovascular structures, and skeletal portions of the bony pelvis. Cases with no cancer-free space between the tumor and pelvic wall by rectal examination are FIGO III. N2: Tumor with regional lymph node metastasis to para-aortic lymph nodes with or without positive pelvic lymph nodes. M0: No distant metastasis. (from AJCC 9th Ed.) [from NCI]
