ReviewPre-treatment surgical para-aortic lymph node assessment in locally advanced cervical cancer.
This is an updated version of the original Cochrane review published in The Cochrane Library, Issue 4, 2011.Cervical cancer is the most common cause of death from gynaecological cancers worldwide. Locally advanced cervical cancer, FIGO stage (International Federation of Gynaecology and Obstetrics) equal or more than IB1 is treated with chemotherapy and external beam radiotherapy followed by brachytherapy. If there is metastatic para-aortic nodal disease, radiotherapy is extended to cover this area. Due to increased morbidity, ideally extended-field radiotherapy is given only when para-aortic nodal disease is confirmed. Therefore, accurate assessment of the extent of the disease is very important for planning the most appropriate treatment. ⋯ Since the last version of this review no new studies were found.From the one available RCT we found insufficient evidence that pre-treatment surgical para-aortic lymph node assessment for locally advanced cervical cancer is beneficial, and it may actually have an adverse effect on survival. However, this conclusion is based on analysis of a small single trial and therefore definitive guidance or recommendations for clinical practice cannot be made.Therefore, the decision to offer surgical pre-treatment assessment of para-aortic lymph nodes in locally advanced cervical cancer needs to be individualised. The uncertainty regarding any impact on survival from pre-treatment para-aortic lymph node assessment should be discussed openly with the women.

ReviewMethods for administering subcutaneous heparin during pregnancy.
Pregnant women with a history of venous thromboembolism (VTE), antithrombin deficiency, or other risk factors for VTE, need heparin (unfractionated heparin (UFH) or low-molecular weight heparin (LMWH)) prophylaxis, mainly through administering subcutaneously. Several methods of administering heparin (UFH or LMWH) subcutaneously have been introduced to prevent adverse pregnant outcomes. The effectiveness and safety of different methods administering subcutaneous heparin (UFH or LMWH) during pregnancy have not been systematically evaluated. ⋯ There is no evidence from randomised controlled trials to evaluate the effectiveness and safety of different methods of administering subcutaneous heparin (UFH or LMWH) to pregnant women.
