Abstract

BackgroundCervical cancer is the second commonest cancer among women up to 65 years of age and is the most frequent cause of death from gynaecological cancers worldwide. Sources suggest that a very high proportion of new cervical cancer cases in developing countries are at an advanced stage (IB2 or more) and more than a half of these may be stage III or IV. Cervical cancer staging is based on findings from clinical examination (FIGO) staging). Standard care in Europe and US for stage IB2 to III is non-surgical treatment (chemoradiation). However in developing countries, where there is limited access to radiotherapy, locally advanced cervical cancer may be treated with a combination of chemotherapy and hysterectomy (surgery to remove the womb and the neck of the womb, with or without the surrounding tissues). It is not certain if this improves survival. Therefore, it is important to systematically assess the value of hysterectomy in addition to radiotherapy or chemotherapy, or both, as an alternative intervention in the treatment of locally advanced cervical cancer (stage IB2 to III).ObjectivesTo determine whether hysterectomy, in addition to standard treatment with radiation or chemotherapy, or both, in women with locally advanced cervical cancer (stage IB2 to III) is safe and effective compared with standard treatment alone.Search methodsWe searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL, MEDLINE, EMBASE and LILACS up to February 2014. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies.Selection criteriaWe searched for randomised controlled trials (RCTs) that compared treatment protocols involving hysterectomy versus radiotherapy or chemotherapy, or both, in women with advanced stage (IB2 to III) cervical cancer presenting for the first time.Data collection and analysisWe assessed study eligibility independently, extracted data and assessed risk of bias. Where possible, overall and progression or diseasefree survival outcomes were synthesised in a meta-analysis using the random-effects model. Adverse events were incompletely reported so results of single trials were described in narrative form.Main resultsWe included seven RCTs (1217 women) of varying methodological quality in the review; most trials were at moderate or high risk of bias.Three were multi-centre trials, two were single-centre trials, and in two trials it was unclear if they were single or multi-centre. These trials compared the following interventions for women with locally advanced cervical cancer (stages IB2 to III):hysterectomy (simple or radical) with radiotherapy (N = 194) versus radiotherapy alone (N = 180); hysterectomy (simple or radical) with chemoradiotherapy (N = 31) versus chemoradiotherapy alone (N = 30); hysterectomy (radical) with chemoradiotherapy (N = 111) versus internal radiotherapy with chemoradiotherapy (N = 100); hysterectomy (simple or radical) with upfront (neoadjuvant) chemotherapy (N = 298) versus radiotherapy alone (N = 273).One trial (N = 256) found no difference in the risk of death or disease progression between women who received attenuated radiotherapy followed by hysterectomy and those who received radiotherapy (external and internal) alone (hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.61 to 1.29). This trial also reported no difference between the two groups in terms of adverse effects (18/129 grade 3 or 4 adverse effects in the hysterectomy and radiation group and 19 cases in 18/121 women in the radiotherapy alone group). There was no difference in 5-year tumour-free actuarial survival (representation of the probable years of survivorship of a defined population of participants) or severe complications (grade 3) in another trial (N = 118) which reported the same comparison (6/62 versus 6/56 in the radiation with surgery group versus the radiotherapy alone group, respectively). The quality of the evidence was low for all t
