Secondary healing strategy for difficult wound closure in invasive vulvar cancer: a pilot case-control study

Abstract

Objectives: Despite the number of surgical advances and innovations in techniques over time, radical vulvectomy frequently results in substantial loss of tissue that cannot be primarily closed without tension, the mobilization of surrounding tissues or even the rotation of myocutaneous flaps. The aim of this study was to evaluate the feasibility of leaving the surgical vulvar open wound for secondary healing in situations where primary closure of the vulvar wound is not possible.

Methods: This case-control pilot study analyzed 16 women with a diagnosis of squamous cell carcinoma of the vulva who first underwent inguinofemoral lymphadenectomy, 6-week sessions of chemotherapy and 25 daily sessions of radiotherapy. Afterward, excision of the vulvar lesion with free margins was performed between January 2011 and July 2017. Twelve patients underwent primary closure of the wound (control), and in 4 patients, the surgical wound was left open for secondary healing by means of a hydrofiber (case). The inclusion criteria were a) FIGO-2009 stage II up to IIIC; b) squamous cell carcinoma; and c) no evidence of pelvic or extrapelvic disease or pelvic nodal involvement. The exclusion criteria were extrapelvic disease or pelvic nodal involvement, another primary cancer, or a poor clinical condition. ClinicalTrials.gov: NCT02067052.

Results: The mean age of the patients at the time of the intervention was 62.1. The distribution of the stages was as follows: II, n=6 (37 %); IIIA, n=1 (6%), IIIB, n=1 (6%) and IIIC, n=8 (51%). The mean operative time was 45 minutes. The hospital stay duration was 2 days. Full vulvar healing occurred after an average of 30 days in the control group and after an average of 50 days in the case group.

Conclusion: A secondary healing strategy may be an option for the treatment of vulvar cancer in situations of non-extensive surgical wounds when primary closure of the wound is not possible.
