Input: The search for the original version of the review identified 635 unique references. We found 31 references (which reported on 30 studies) in full text after inspection of titles and abstracts, but we excluded them all as they did not meet the inclusion criteria. However, we have included a comprehensive narrative account of studies where we identified an analysis of more than 10 women, as this forms the only evidence base in this rare disease. Surgery continues to be the mainstay of treatment in the current literature, with other treatments limited to case reports or treatment of inoperable or recurrent disease. This update between September 2013 and May 2018 identified 35 new studies. None of these met the inclusion criteria. There was only one prospective study of 5% imiquimod in recurrent Paget's disease of the vulva, which although of good quality only included eight women. Since the last version of the review was published there are many more cases in the literature reporting a clinical response to 5% imiquimod cream. There is one prospective study of eight women treated with 5% imiquimod for recurrent Paget's disease of the vulva, and one prospective trial of 20 women was due to be reported. This increasing evidence for the safety and efficacy of 5% imiquimod will be helpful for women and clinicians alike. Ideally, a multicentre RCT of reasonable size is needed, but ongoing publications of high-quality non-randomised prospective studies will enhance the current available literature.
Output:

We searched for randomised controlled trials (trials where treatment is allocated to women in a random manner) and well-designed non-randomised studies that compared different treatments in women aged 18 years or older with biopsy-confirmed Paget's disease of the vulva. We searched scientific databases and contacted experts and identified and checked the titles and abstracts of 635 possibly relevant articles and retrieved 31 of these references in full text. However, we found no studies that met our inclusion criteria. We identified several non-randomised studies and drafted a detailed narrative of their results, but these studies were of poor quality and were at high risk of bias. Therefore, there is currently no evidence to determine whether any form of treatment is better or worse in terms of prolonging survival, delaying progression or recurrence, improving QoL or minimising toxicity. The review highlights the need for good-quality studies comparing different interventions for the management of Paget's disease of the vulva. Women and clinicians would value more evidence for guiding surgical and non-surgical management of this disease. In particular, non-invasive medical management would spare women from the side effects and consequences of surgery.
