Treatment Option Overview
Five randomized phase III trials have shown an overall survival advantage for
cisplatin-based therapy given concurrently with radiation therapy,[1-6] while one
trial examining this regimen demonstrated no benefit.[7] The patient
populations in these studies included women with Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stages IB2 to IVA
cervical cancer treated with primary radiation therapy and women with FIGO
stages I to IIA disease found to have poor prognostic factors (metastatic
disease in pelvic lymph nodes, parametrial disease, or positive surgical
margins) at the time of primary surgery. Although the positive trials vary in terms of the stage of disease, dose of radiation, and schedule of
cisplatin and radiation, the trials demonstrate significant survival benefit for
this combined approach. The risk of death from cervical cancer was decreased
by 30% to 50% with the use of concurrent chemoradiation therapy. Based on these results, strong
consideration should be given to the incorporation of concurrent cisplatin-based chemotherapy with radiation therapy in women who require radiation
therapy for treatment of cervical cancer.[1-8]
Pretreatment surgical staging is the most accurate method to determine extent
of disease. Because there is little evidence to demonstrate overall improved
survival with routine surgical staging, it usually should be performed only as
part of a clinical trial. Pretreatment surgical staging in bulky but locally
curable disease may be indicated in select cases when a nonsurgical search for
metastatic disease is negative. If abnormal nodes are detected by computed tomography scan or
lymphangiography, fine-needle aspiration should be negative before a surgical
staging procedure is performed. Surgery and radiation therapy are equally
effective for early-stage small-volume disease.[9] Younger patients may
benefit from surgery in regard to ovarian preservation and avoidance of
vaginal atrophy and stenosis.
Patterns of care studies clearly demonstrate the negative prognostic effect of
increasing tumor volume. Treatment, therefore, may vary within each stage as
currently defined by FIGO and will depend on tumor bulk and spread
pattern.[10]
Therapy of patients with cancer of the cervical stump is effective, yielding
results comparable to those seen in patients with an intact uterus.[11]
During pregnancy, no therapy is warranted for preinvasive lesions of the
cervix, including carcinoma in situ, though expert colposcopy is recommended
to exclude invasive cancer.
Treatment of invasive cervical cancer during pregnancy depends on the stage of
the cancer and gestational age at diagnosis. The traditional approach is to
recommend immediate therapy appropriate for the disease stage when the cancer
is diagnosed before fetal maturity and to delay therapy only if the cancer is
detected in the final trimester.[12,13] However, other reports suggest that
deliberate delay of treatment to allow improved fetal outcome may be a reasonable option for
patients with stage IA and early IB cervical cancer.[14-16]
