Either radiation therapy or radical hysterectomy results in cure rates of 75% to 80%. The selection of either option depends on patient factors and local expertise. A randomized trial reported identical 5-year overall survival (OS) and disease-free survival rates when radiation therapy was compared with radical hysterectomy. The size of the primary tumor is an important prognostic factor and should be carefully evaluated in choosing optimal therapy. For patients with bulky (>6 cm) endocervical squamous cell carcinomas or adenocarcinomas, treatment with high-dose radiation therapy will achieve local control and survival rates comparable to treatment with radiation therapy plus hysterectomy. Surgery after radiation therapy may be indicated for some patients with tumors confined to the cervix that respond incompletely to radiation therapy or in whom vaginal anatomy precludes optimal brachytherapy.
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. The resection of macroscopically involved pelvic nodes may improve rates of local control with postoperative radiation therapy. Treatment of patients with unresected periaortic nodes with extended-field radiation therapy leads to long-term disease control in those patients with low volume (<2 cm) nodal disease below L3. A single study (RTOG-7920) showed a survival advantage in patients who received radiation therapy to para-aortic nodes without histologic evidence of disease. Toxic effects were greater with para-aortic radiation than with pelvic radiation alone but were mostly confined to patients with prior abdominopelvic surgery. 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) after radical surgery may also benefit from pelvic radiation therapy.
Nearly two decades ago, experts discovered a relationship between infection with HPV (human papillomavirus) and cervical cancer. Since then, these experts have learned much more about how HPV can lead to cervical cancer.
Here, what every woman and girl should know about this link.
Five randomized, phase III trials have shown an OS advantage for cisplatin-based therapy given concurrently with radiation therapy,[11,12,13,14,15,16,17] while one trial examining this regimen demonstrated no benefit. The patient populations in these studies included women with Féderation Internationale de Gynécologie et d'Obstétrique (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:
