Abstract
Purpose or Objective The UK vulvar cancer audit showed the widespread use of IMRT in the UK with minimal organ toxicity. However, there was considerable dose range variation with no UK consensus regarding the minimum dose to improve local control (1). The international consensus guidelines for the contouring and treatment of vulvar cancer do not reflect UK practice (2).We aimed to develop recommendations to deliver consistent RT treatment of vulvar cancer in the UK with greater standardisation of dose prescribing and reporting. Materials and Methods The Royal College of Radiologists (RCR) invited a group of gynaecology Clinical Oncology experts to develop consensus recommendations. Draft guidelines were written using the outcomes of the 2019/2020 RCR national vulvar cancer radiotherapy audit. The Consensus group then refined the guidelines through regular meetings and discussions, using a modified Delphi process. The RCR hosted an online contouring exercise where a second expert panel contoured two vulvar cancer cases (radical radiotherapy alone and post-operative nodal fields) before and after reading the consensus recommendations. Further changes were made and the draft recommendations were presented at a British Gynaecological Cancer Society workshop after which final changes were made. Results Consensus recommendations define volumes to contour (table 1) with structured contouring guidelines containing example images. Figure 1 recommends dose/fractionation schemes. Guidance is also given regarding treatment planning, dosimetric parameters and care on treatment. Conclusion We believe these recommendations will standardise the RT treatment of vulvar cancer in the UK. We also aim to improve compliance with national recommendations such as the treatment of vulvar cancer as category 1 and compensation of gaps during treatment. The national RCR audit will be repeated in 2024 to assess the impact of these recommendations on UK practice.
