Selection criteria and colpotomic approach for safe minimally invasive radical hysterectomy in early-stage cervical cancer / 부인종양

Objective@#To evaluate oncologic outcomes of minimally invasive radical hysterectomy (RH) in early cervical cancer before and after the application of parametrial invasion (PMI) criterion on magnetic resonance imaging (MRI) and vaginal colpotomy (VC). @*Methods@#A total of 216 International Federation of Gynecology and Obstetrics stage IB–IIA cervical cancer patients who underwent minimally invasive RH was identified between April 2006 and October 2018. Patients were classified into the pre-PMI intracorporeal or VC (IVC) (n=117) and post-PMI VC groups (n=99). In the pre-PMI IVC group, PMI criterion (intact stromal ring) on MRI was not applied and the patients received IVC. In the post-PMI VC group, surgical candidates were selected using the PMI criterion on MRI and all patients received VC only. Oncologic outcomes and prognostic factors associated with disease recurrence were analyzed. @*Results@#The rate of positive vaginal cuff margins in the pre-PMI IVC group was higher than that in the post-PMI VC group (11.1% vs. 1.0%, p=0.003). Two-year disease-free survival was different between the 2 groups (84.5% in pre-PMI IVC vs. 98.0% in post-PMI VC groups, p=0.005). Disrupted stromal ring on MRI (hazard ratio [HR]=20.321; 95% confidence interval [CI]=4.903–84.218; p<0.001) and intracorporeal colpotomy (HR=3.059; 95% CI=1.176–7.958; p=0.022) were associated with recurrence. @*Conclusion@#The intact cervical stromal ring on MRI might identify the low-risk group of patients in terms of PMI and lymphovascular/stromal invasion in early cervical cancer. Minimally invasive RH should be performed in optimal candidates with an intact stromal ring on MRI, using VC.

Clinicopathologic characteristics of ovarian clear cell carcinoma in the background of endometrioma: a surveillance strategy for an early detection of malignant transformation in patients with asymptomatic endometrioma

OBJECTIVE: This study aimed to analyze the clinical features of clear cell carcinoma in relation to endometriosis and to determine an appropriate surveillance strategy for the early detection of malignant transformation of endometrioma in asymptomatic patients. METHODS: We retrospectively reviewed the clinicopathologic data of 50 patients with ovarian clear cell carcinoma. Clinicopathologic characteristics, treatment outcomes, and the association between endometriosis and the risk of malignant transformation were analyzed. RESULTS: Ten (20%) patients had been diagnosed with endometrioma before the diagnosis of clear cell carcinoma. The median period from the diagnosis of endometrioma to clear cell carcinoma diagnosis was 50 months (range, 12–213 months). After complete staging surgery, histological confirmation of endometriosis was possible in 35 (70%) patients. Of the 50 patients, 39 (78%) had not undergone any gynecologic surveillance until the onset of symptoms, at which time many of them presented with a rapidly growing pelvic mass (median 10 cm, range 4.6–25 cm). With the exception of 2 patients, all cancer diagnoses were made when the patients were in their late thirties, and median tumor size was found to increase along with age. Asymptomatic patients (n=11) who had regular gynecologic examinations were found to have a relatively smaller tumor size, lesser extent of tumor spread, and lower recurrence rate (P=0.011, 0.283, and 0.064, respectively). The presence of endometriosis was not related to the prognosis. CONCLUSION: Considering the duration of malignant transformation and the timing of cancer diagnosis, active surveillance might be considered from the age of the mid-thirties, with at least a 1-year interval, in patients with asymptomatic endometrioma.

Prediction of lymph node metastasis in patients with apparent early endometrial cancer

OBJECTIVE: The purpose of this study is to investigate the incidence of lymph node metastasis in early endometrial cancer patients and to evaluate preoperative clinicopathological factors predicting lymph node metastasis. METHODS: We identified 142 patients with endometrial cancer between January 2000 and February 2013. All patients demonstrated endometrioid adenocarcinoma with grade 1 or 2 on preoperative endometrial biopsy. Preoperative magnetic resonance imaging showed that tumors were confined to the uterine corpus with superficial myometrial invasion (less than 50%), and there were no lymph nodes enlargements. All patients had complete staging procedures and were surgically staged according to the 2009 FIGO (International Federation of Gynecology and Obstetrics) staging system. Clinical and pathological data were obtained from medical records and statistically analyzed. RESULTS: Of the 142 patients, 127 patients (89.4%) presented with stage 1A, 8 (5.6%) with stage IB, 3 (2.1%) with stage II, and 4 (2.8%) with stage III disease. Three patients (2.1%) had lymph node metastasis-2 IIIC1 and 1 IIIC2 disease. Age, preoperative tumor grade, and myometrial invasion less than 50% on preoperative MRI were not associated with lymph node metastasis. A high preoperative serum CA-125 level (>35 IU/mL) was a statistically significant factor for predicting lymph node metastasis on univariate and multivariate analyses. Lymph node metastasis was only found in patients with preoperative grade 2 tumors or a high serum CA-125 level. CONCLUSION: Preoperative tumor grade and serum CA-125 level can predict lymph node metastasis in apparent early endometrial cancer patients.

Neoadjuvant and postoperative chemotherapy with paclitaxel plus cisplatin for the treatment of FIGO stage IB cervical cancer in pregnancy

Cervical cancer is one of the most common malignancy diagnosed during pregnancy. The experience of the use of neoadjuvant chemotherapy (NACT) with paclitaxel plus cisplatin during pregnancy is limited. Three pregnant women with International Federation of Gynecology and Obstetrics (FIGO) stage IB cervical cancer received NACT with paclitaxel plus cisplatin until fetal lung maturity, and then underwent cesarean delivery and radical hysterectomy. Two of our patients had intermediate pathologic risk factors, and received adjuvant chemotherapy with the same regimen used in NACT. All patients did not have any evidence of disease recurrence for follow-up of 3, 4, and 8 years, respectively. NACT with paclitaxel plus cisplatin followed by radical hysterectomy and adjuvant chemotherapy could be considered as one of feasible alternatives to primary radical surgery or concurrent chemoradiation therapy with the termination of pregnancy in pregnant women with FIGO stage IB cervical cancer who have two or more intermediate pathologic-risk factors.

Outcome of pelvic arterial embolization for postpartum hemorrhage: A retrospective review of 117 cases

OBJECTIVE: The aim of this study was to evaluate indications, efficacy, and complications associated with pelvic arterial embolization (PAE) for postpartum hemorrhage (PPH). METHODS: We retrospectively reviewed the medical records of 117 consecutive patients who underwent PAE for PPH between January 2006 and June 2013. RESULTS: In our single-center study, 117 women underwent PAE to control PPH refractory to conservative management including uterine massage, use of uterotonic agents, surgical repair of genital tract lacerations, and removal of retained placental tissues. Among 117 patients, 69 had a vaginal delivery and 48 had a Cesarean section. The major indication for embolization was uterine atony (54.7%). Other causes were low genital tract lacerations (21.4%) and abnormal placentation (14.5%). The procedure showed a clinical success rate of 88.0% with 14 cases of PAE failure; there were 4 hemostatic hysterectomies and 10 re-embolizations. On univariate analysis, PAE failure was associated with overt disseminated intravascular coagulation (P=0.009), transfusion of more than 10 red blood cell units (RBCUs, P=0.002) and embolization of both uterine and ovarian arteries (P=0.003). Multivariate analysis showed that PAE failure was only associated with transfusions of more than 10 RBCUs (odds ratio, 8.011; 95% confidence interval, 1.531-41.912; P=0.014) and embolization of both uterine and ovarian arteries (odds ratio, 20.472; 95% confidence interval, 2.715-154.365; P=0.003), which were not predictive factors, but rather, were the results of longer time for PAE. Three patients showed uterine necrosis and underwent hysterectomy. CONCLUSION: PAE showed high success rates, mostly without procedure-related complications. Thus, it is a safe and effective adjunct or alternative to hemostatic hysterectomy, when primary management fails to control PPH.
