Agenda Epidemiology. Where do we stand? Management of Cervical Cancer. Radiotherapy Evolution: -From 2D to IMRT.
Epidemiology Globally, cervical cancer is also the second most common cause of cancer-related mortality causing approximately 234,000 deaths annually among developing countries yet only killing 40,000 women in developed nations.

Primary Prevention
Vaccination is currently approved for use in girls and women ages 9 to 26 years.
Secondary Prevention
Screening should begin at age 21 years. Cytology alone is recommended every 3 years for women years of age. For women years of age, cotesting every 5 years is recommended. If HPV testing is not available, cytology alone should be continued every 3 years. New Screenin guidelines Saslow D, et al. American Cancer Society, American Society for Colposcopy and Cervical Pathology, and American Society for Clinical Pathology screening guidelines for the prevention and early detection of cervical cancer.

Where Do We Stand Radiotherapy and Cervical Cancer
Radiotherapy For Early Stage Disease
Early Stage I &II Early Stages (I &II) Stage I A1 - A2 Stage I B1 - B2 Stage II A1 - A2 Stage II A1 - A2
Inoperable patients
Stage IB and IIA bulky
Reduction in the risk of recurrence by up to 50% in the postoperative setting
Which Way? TREATMENT
Early Stage I &II Late Stages IIIA &IIIB Stage IIIA = N2 disease or T3 N1 Stage IIIA = N2 disease or T3 N1 Late Stages IIIA &IIIB Stage IIIA&B Late Stages IIIA &IIIB Stage IVA Late Stages IIIA &IIIB Late Stages IIB, III &VIA Stage IIB
Green J, Kirwan J, Tierney J, et al. Concomitant chemotherapy and radiation therapy for cancer of the uterine cervix. Cochrane Database Syst Rev 2001:CD A meta-analysis that included 4580 patients from 19 randomized trials supported the NCI consensus and confirms that concurrent chemo-radiation is superior to radiotherapy alone in terms of higher local control and decreased incidence of distant relapses with both platinum and non-platinum chemotherapy. Absolute Benefit of 10 to 13% in OAS
