Staging

Criteria for TNM Clinical Staging: Standard clinical staging for cervical carcinoma is that which is available at any community hospital. This includes physical examination and history, palpation of abdomen and pelvis, endocervical curettage, colposcopy, cystoscopy, proctoscopy, intravenous urography, hysteroscopy and imaging of the abdomen, lungs and bones. Additional procedures, such as laparoscopy, lymphangiography, venography and arteriography may better define the extent of the cancer, but should not influence staging.

Criteria for TNM Pathologic Staging: Pathologic review of resected specimens adds detailed staging information to the case, but should be recorded separately and should not be used to change the clinical staging.

Clinical staging is the preferred staging for cervical cancer. The clinical staging of cervical cancer should never be changed based on additional findings at surgery or later clinical findings.

Staging for cervical tumors applies only to carcinomas, not to sarcomas or other histologies.
