Cervical Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage IB Cervical Cancer

Either radiation therapy or radical hysterectomy and bilateral lymph node dissection results in cure rates of 85% to 90% for women with Féderation Internationale de Gynécologie et d'Obstétrique (FIGO) stages IA2 and IB1 small-volume disease. The choice of either treatment depends on patient factors and available local expertise. A randomized trial reported identical 5-year overall survival (OS) and disease-free survival rates when comparing radiation therapy to radical hysterectomy.[1] The size of the primary tumor is an important prognostic factor and should be carefully evaluated in choosing optimal therapy.[2] For adenocarcinomas that expand the cervix more than 4 cm, the primary treatment should be concomitant chemotherapy and radiation therapy.[3]

After surgical staging, patients found to have small volume para-aortic nodal disease and controllable pelvic disease may be cured with pelvic and para-aortic radiation therapy and concomitant chemotherapy.[4] The resection of macroscopically involved pelvic nodes may improve rates of local control with postoperative chemotherapy and radiation therapy.[5] Treatment of patients with unresected periaortic nodes with extended-field radiation therapy and chemotherapy leads to long-term disease control in those patients with low volume (<2 cm) nodal disease below L3.[6] A single study (RTOG-7920) showed a survival advantage in patients with tumors larger than 4 cm who received radiation therapy to para-aortic nodes without histologic evidence of disease.[7] Toxic effects were greater with para-aortic radiation therapy than with pelvic radiation therapy alone but were mostly confined to patients with prior abdominopelvic surgery.[7] Patients who underwent extraperitoneal lymph node sampling had fewer bowel complications than those who had transperitoneal lymph node sampling.[6,8,9] Patients with close vaginal margins (<0.5 cm) may also benefit from pelvic radiation therapy.[10]

Understanding Cervical Cancer -- Prevention

Since infection with human papillomavirus (HPV) is the most important risk factor for cervical cancer and precancers, it is important to avoid genital HPV infection. This may mean delaying sex, limiting the number of sex partners, and avoiding a sex partner who has had several other partners. Condoms are important to prevent the spread of sexually transmitted diseases, but they can't give full protection against HPV since there may be skin to skin contact of exposed areas which can transmit the virus...

Five randomized, phase III trials have shown an OS advantage for cisplatin-based therapy given concurrently with radiation therapy,[11,12,13,14,15,16] while one trial examining this regimen demonstrated no benefit.[17] The patient populations in these studies included women with FIGO stages IB2 to IVA cervical cancer treated with primary radiation therapy, and women with FIGO stages I to IIA disease who, at the time of primary surgery, were found to have poor prognostic factors, which included the following:

  • Metastatic disease in pelvic lymph nodes.
  • Parametrial disease.
  • Positive surgical margins.
