However, the morbidity of RP was high. The aim of our study is to assess the incidence of parametrial involvement in patients who underwent radical parametrectomy for occult cervical cancer or radical hysterectomy for early?stage cervical cancer and to suggest an algorithm for the triage of patients with occult cervical cancer to avoid RP.Methods: A total of 13 patients with occult cervical cancer who had undergone RP with an upper vaginectomy and pelvic lymphadenectomy were included in this retrospective study. Data on the clinicopathologic characteristics of the cases were collected. The published literature was also reviewed, and low risk factors for parametrial involvement in early?stage cervical cancer were analyzed.Results: Of the 13 patients, 9 had a stage IB1 lesion, and 4 had a stage IA2 lesion. There were four patients with grade 1 disease, seven with grade 2 disease, and two with grade 3 disease. The median age of the entire patients was 41 years. The most common indication for extrafascial hysterectomy was cervical intraepithelial neoplasia 3. Three patients had visible lesions measuring 10–30 mm, in diameter and ten patients had cervical stromal invasions with depths ranging from 4 to 9 mm; only one patient had more than 50% stromal invasion, and four patients had lymph?vascular space invasion(LVSI). Perioperative complications included intraoperative bowel injury, blood transfusion, vesico?vaginal istula, and ileus(1 case for each). Postoperative pathologic examination results did not show residual disease or parametrial involvement. One patient with positive lymph nodes received concurrent radiation therapy. Only one patient experienced recurrence.Conclusions: Perioperative complications following RP were common, whereas the incidence of parametrial involve?ment was very low among selected early?stage cervical cancer patients. Based on these results, we thought that patients with very low?risk parametrial involvement(tumor size ≤2 cm, no LVSI, less than 50% stromal invasion, nega?tive lymph nodes) may beneit from omitting RP. Further prospective data are warranted.展开更多

Of these patients, 368 underwent separate dissection of PLNs using the LPLND method, and 2,327 patients underwent conventional radical hysterectomy(CRH). We compared the surgical parameters, PLN detection rate and PLN metastasis rate between the two groups.Results: Compared with CRH group, the rate of laparoscopic surgery was higher(60.3% vs. 15.9%, P<0.001),and the blood transfusion rate was lower(19.0% vs. 29.0%, P<0.001) in the LPLND group. PLNs were detected in 356 cases(96.7%) in the LPLND group, and 270 cases(11.6%) in the CRH group(P<0.001), respectively. The number of PLNs detected in the LPLND group was higher than that in the CRH group(median 3 vs. 1, P<0.001).The PLN metastases were detected in 25 cases(6.8%) in the LPLND group, and 18 cases(0.8%) in the CRH group(P<0.001), respectively. In multivariable analysis, LPLND is an independent factor not only for PLN detection [odds ratio(OR)=228.999, 95% confidence interval(95% CI): 124.661-420.664;P<0.001], but also for PLN metastasis identification(OR=10.867, 95% CI: 5.381-21.946;P<0.001).Conclusions: LPLND is feasible and safe. The surgical method significantly improves the detection rate of PLN and avoids omission of PLN metastasis during radical hysterectomy for early-stage cervical cancer.展开更多
