Show moreBackgroundUp to 40% of vulvar cancer patients present with local recurrence within 10 years of follow-up. An inguinofemoral lymphadenectomy (IFL) is indicated if not performed at primary treatment. The incidence and risk factors for lymph node metastases (LNM) at first local recurrence, however, are unclear. Our aim was to determine the incidence of LNM at first local recurrence, in relation to previous groin treatment and clinicopathological factors.MethodsA multicenter cohort study including vulvar cancer patients with a first macroinvasive local recurrence after primary surgical treatment between 2000 and 2015 was conducted in the Netherlands. Groin status at local recurrence was defined as positive (N+), negative (N-) or unknown (N?) and based on histology, imaging and follow-up. Patient-, tumour- and treatment characteristics of primary and recurrent disease were analysed.ResultsOverall, 16.3% (66/404) had a N+groin status at first local recurrence, 66.4% (268/404) N- and 17.3% (70/404) N?groin status. The incidence of a N+groin status was comparable after previous SLN and IFL, 11.5% and 13.8%, respectively. A N+ groin status was related to tumour size (25 vs.12 mm; P < 0.001), depth of invasion (5 vs. 3 mm; P < 0.001) and poorly differentiated tumours (22.9 vs. 11.9%; P = 0.050) at local recurrence.ConclusionsThe incidence of LNM at first local recurrence in vulvar cancer patients was 16.3%, and independent of previous type of groin surgery. In accordance with primary diagnosis, tumour size, depth of invasion, and tumour grade were significantly associated with a positive groin status. Show less

Show morePurpose of review Studies on treatment options for patients with locally advanced vulvar cancer (LAVC) are scarce, and high-level evidence for a primary treatment choice is lacking. Furthermore, current treatment options are associated with extensive morbidity and high complication rates. More effective treatment options are urgently needed. This review describes current treatment possibilities, focusing on literature regarding neoadjuvant chemotherapy (NACT) followed by surgery. Recent findings Although data are heterogeneous and limited, NACT followed by surgery might be an effective and well tolerated treatment alternative associated with lower morbidity compared with current treatment options, such as excenterative surgery or definitive chemoradiation. Up until now, several studies describe an overall response rate of 40-86%. Surgery turned out to be possible in 40-90% of the LAVC patients who received NACT. Prospective studies on the efficacy and safety of NACT followed by surgery with a homogeneous chemotherapy regimen are urgently awaited. NACT should, at this point, still be considered investigational. Show less
