Background Since the introduction of sentinel node biopsy (SLNB) in unifocal vulvar cancer (diameter of < 4 cm) and unsuspicious groin lymph nodes, the morbidity rate of patients has significantly decreased globally. In contrast to SLNB, bilateral inguinofemoral lymphadenectomy (IFL) has been associated with increased risk of common morbidities. Current guidelines (NCCN, ESGO, RCOG, and German) recommend that in cases of unilaterally positive sentinel lymph node (SLN), bilateral IFL should be performed. However, two recent publications by Woelber et al. and Nica et al. contradict the current guideline, since a significant rate of positive non sentinel lymph nodes in IFL contralaterally was not observed [Woelber et al. 0% (p = 0/28) and Nica et al. 5.3% (p = 1/19)]. Methods A retrospective single-center analysis conducted in the University Hospital of Dusseldorf, evaluating vulvar cancer patients treated with SLNB from 2002 to 2018. Results 22.2% of women (n = 4/18) were found to have contralateral IFL groin metastasis after an initial diagnosis of unilateral SLN metastasis. The depth of tumor infiltrating cells correlated significantly and positively with the rate of incidence of groin metastasis (p = 0.0038). Conclusion Current guideline for bilateral IFL should remain as the standard management. Therefore, this depth may be taken into account as an indication for bilateral IFL. The management of VC and SLNB should be performed in a high volume center with an experienced team in marking SLN and performing the adequate surgical procedure. Well conducted counseling of the patients outlining advantages but also potential oncological risks of this technique especially concerning rate of groin recurrence is critical.

Background: Sentinel node biopsy (SLNB) technique in unifocal vulvar cancer (diameter of < 4cm) and unsuspicious groin lymph nodes, the morbidity rate of patients has significantly decreased all over the world. In contrast to SLNB, bilateral inguinofemoral lymphadenectomy (IFL) has been associated with increased risk of common morbidities. Current guidelines (NCCN, ESGO, RCOG, and German) suggest that in cases of metastasis of unilateral SLNB, groin node dissection with IFL, should be performed bilaterally. However, a publication by Woelber et al. 0% (p=0/28) and Nica et al. 5.3% (p=1/19) contradicted the current guideline. Methods: A single-center analysis conducted in the University Hospital of Dusseldorf, evaluating vulvar cancer patients treated with SLNB retrospectively from 2002 to 2018. Result, discussion and conclusion: Current guideline for bilateral IFL should remain as the standard management because 22.2% women (n=4/18) had contralateral IFL groin metastasis after unilateral SLNB metastasis initially. The depth of tumor infiltrating cells was correlated significantly and positively with the incidence rate of groin metastasis (p=0.0038). Therefore, it is an indication for bilateral IFL.

Background/Purpose: This study aims to investigate whether women with cervical dysplasia after LEEP have an increased risk of pregnancy/childbirth complications or recurrence of dysplasia in an upcoming pregnancy. Methods: Data from 240 women after LEEP were analysed retrospectively. The reference group consisted of 956 singleton births. Fisher and Wilcoxon rank tests were used to detect differences between groups. Using logistic regressions, we analysed the effect of surgery specific aspects of LEEP on pregnancy/childbirth complications and the frequency of CIN recurrences. Results: We found that tissue preserving LEEP did not lead to premature birth or miscarriage and did not increase the likelihood of CIN recurrence. We did not observe differences regarding preterm birth (< 37 (p < 0.28) < 34 (p < 0.31), < 32 weeks of gestation (p < 0.11)) or birth weight (< 2500g (p < 0.54), < 2000g (p < 0.77) between groups. However, women after LEEP exhibit a higher risk of premature rupture of membranes 2 (PROM) at term (p < 0.009) and vaginal infections (p < 0.06). Neither volume nor depth of the removed tissue nor an additional endocervical resection seem to influence the likelihood of premature birth or early miscarriage. Performing an endocervical resection protects against CIN recurrence (OR = 0.0881, p < 0.003). Conclusions: After tissue-preserving LEEP, there is an increased risk of vaginal infections and PROM at term in consecutive pregnancy. LEEP does not affect prematurity or miscarriage. The removal of additional endocervical tissue appears to be a protective factor against recurrence of CIN.
