BACKGROUND: The intravenous injection of rocuronium bromide is often painful, and different methods have been used to minimize the incidence and severity of this pain. This study determined the effective dose of alfentanil to minimize the injection pain of rocuronium and the cardiovascular response after endotracheal intubation. METHODS: Eighty ASA physical status 1 and 2 adult patients were divided into four groups. Sixty seconds before administering rocuronium 0.6 mg/kg, the groups were given 10 ml of intravenous normal saline or alfentanil 10, 15, and 20microgram/kg. Pain was assessed after rocuronium injection. The mean arterial pressure and heart rate were measured before induction and before and after intubation. RESULTS: Both 15 and 20microgram/kg alfentanil minimized the rocuronium injection pain, although 20microgram/kg alfentanil caused an undesirable decrease in the mean arterial pressure. CONCLUSIONS: A 15microgram/kg bolus of alfentanil may be useful for minimizing the rocuronium injection pain and blunting the cardiovascular response after endotracheal intubation.

Objective:
Unlike cervical squamous cell carcinoma, there are no consensus criteria for serum tumor markers in cervical adenocarcinoma. This study aimed to identify the prognostic value of preoperative carbohydrate antigen 125 (CA125) levels in cervical adenocarcinoma patients with adverse pathologic features.
Methods:
A total of 105 patients who underwent radical hysterectomy followed by adjuvant radiotherapy (RT) or concurrent chemoradiation therapy were included. Locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS) were evaluated using the Cox proportional hazard regression model.
Results:
Using a cutoff value of 50 U/mL, 83 and 22 patients had low- and high-CA125, respectively. Patients with high-CA125 had a larger tumor size, more frequent parametrial extension, and more frequent lymph node metastasis than those with low-CA125. During a median follow-up of 59.3 (interquartile range, 32.7–97.8) months, patients with high-CA125 showed inferior 5-year LRFS, DMFS, and OS rates compared to those with low-CA125 (38.5% vs. 70.0%; 37.0% vs. 69.4%; 43.6% vs. 78.1%, respectively, all p<0.05). In multivariable analysis, the high-CA125 remained significant prognostic factor for LRFS, DMFS, and OS (all p<0.05). Furthermore, 12 patients with high-CA125 at recurrence exhibited lower 5-year OS rates than 21 patients with low-CA125 at recurrence (0.0% vs. 51.3%, p=0.003).
Conclusion
In this retrospective analysis, the serum CA125 level at diagnosis and recurrence was related to the extent of disease and prognosis of cervical adenocarcinoma with adverse pathologic features. A CA125 level of ≥50 U/mL may be a prognostic surrogate marker for cervical adenocarcinoma in patients with the presence of adverse factors.

Purpose:
This study aimed to identify the prognostic value of early metabolic response assessed using 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) during radiation therapy (RT) for cervical cancer.
Materials and Methods:
We identified 116 patients treated with definitive RT, including FDG-PET/CT–guided intracavitary brachytherapy, between 2009 and 2018. We calculated parameters including maximum (SUVmax) and mean standardized uptake values (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) for baseline FDG-PET/CT (PETbase) and image-guided brachytherapy planning FDG-PET/CT (PETIGBT). Multivariable analyses of disease-free survival (DFS) and overall survival (OS) were performed.
Results:
We observed a time-dependent decrease in PET parameters between PETbase and PETIGBT; ΔSUVmax, ΔSUVmean, ΔMTV, and ΔTLG were 65%, 61%, 78%, and 93%, respectively. With a median follow-up of 59.5 months, the 5-year DFS and OS rates were 66% and 79%, respectively. Multivariable analysis demonstrated that ΔSUVmax ≥ 50% was associated with favorable DFS (hazard ratio [HR], 2.56; 95% confidence interval [CI], 1.14 to 5.77) and OS (HR, 5.14; 95% CI, 1.55 to 17.01). Patients with ΔSUVmax ≥ 50% (n=87) showed better DFS and OS than those with ΔSUVmax < 50% (n=29) (DFS, 76% vs. 35%, p < 0.001; OS, 90% vs. 41%, p < 0.001, respectively). Adenocarcinoma was frequently observed in ΔSUVmax < 50% compared to ΔSUVmax ≥ 50% (27.6% vs. 10.3%, p=0.003). In addition, models incorporating metabolic parameters showed improved accuracy for predicting DFS (p=0.012) and OS (p=0.004) than models with clinicopathologic factors.
Conclusion
Changes in metabolic parameters, especially those in SUVmax by > 50%, can help improve survival outcome predictions for patients with cervical cancer treated with definitive RT.

Objective:
The recently updated World Health Organization classification divides endocervical adenocarcinomas (ADCs) into human papillomavirus (HPV)-associated (HPVA) and HPV-independent (HPVI) ADCs. This study aimed to investigate the differences in the clinical features and treatment outcomes between patients with HPVA and HPVI.
Methods:
We retrospectively reviewed the electronic medical records and pathology slides of 123 patients with endocervical ADC who underwent radical hysterectomy and adjuvant radiation therapy. Tumor characteristics, patterns of failure, and survival outcomes were compared between HPVA and HPVI ADCs.
Results:
Eighty-one (65.9%) and 42 (34.1%) patients were diagnosed with HPVA and HPVI ADCs, respectively. HPVI ADC showed more frequent positive vaginal resection margin (VRM) and peritoneal seeding than HPVA ADC. After a median follow-up of 58.1 months, local recurrence and distant metastasis were more frequently observed in HPVI ADC than in HPVA ADC. Both local recurrence-free survival (77.3% vs. 91.8%) and distant metastasis-free survival (50.1% vs. 73.7%) rates of HPVI ADC were lower than those of HPVA ADC. Disease-free survival was not significantly different between HPVI and HPVA ADCs.
Conclusion
We demonstrated that HPVI ADC exhibited higher rates of VRM involvement and peritoneal seeding than those of HPVA ADC, resulting in higher rates of local recurrence and distant metastasis. Further studies with larger populations are warranted to explore optimal treatment strategies based on the histological subtypes of endocervical ADC.

OBJECTIVE: This study was designed to compare survival outcomes of patients with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CC) to those of patients with grade 3 endometrioid carcinoma (G3EC) according to 1988 and 2009 International Federation of Gynecology and Obstetrics (FIGO) staging systems. METHODS: We retrospectively reviewed all patients with endometrial cancer treated at a single institution between 1995 and 2009. Among the 647 patients with endometrial cancer, 51 with G3EC and 46 with UPSC and CC histology were confirmed. RESULTS: 1988 FIGO stage, 2009 FIGO stage, and extrauterine metastasis were significantly different between the UPSC and CC group and G3EC group (p=0.002, p=0.041, and p=0.020, respectively). Restaging from the 1988 FIGO to the 2009 FIGO criteria increased the number of stage I cases by 10 (11.0%). Overall, 8 in the UPSC and CC and 2 in the G3EC group were down-staged to stage I. In the UPSC and CC group, the 3-year overall survival for 1988 FIGO stage I was 92.9%. When UPSC and CC patients were restaged using the 2009 staging system, the 3-year overall survival of 2009 FIGO stage I dropped to 81.6%. UPSC and CC was associated with poor OS outcome compared with G3EC, after adjustment for 2009 FIGO stage and other clinicopathologic factors. CONCLUSION: We observed that UPSC and CC patients had different prognosis according to the old and new FIGO staging system. Our results suggest that UPSC and CC compared with the G3EC may retain the 1988 FIGO to be a slightly better discriminator than 2009 FIGO.

OBJECTIVE: This study was conducted to compare the perioperative outcomes in patients with symptomatic uterine myoma who underwent laparoscopic (LM) or laparoscopically assisted myomectomy (LAM). METHODS: A total of 207 patients with myoma underwent LM or LAM in Samsung Medical Center between October 2006 and March 2010. Of them, 121 patients with LM and 50 with LAM met the inclusion criteria and were compared for the perioperative outcomes. RESULTS: The operation time was significantly shorter in the LAM group than in the LM group (111 min versus 139 min; p<.001, respectively). Estimated blood loss was significantly higher in the LAM group (p<.001). Intraoperative, early postoperative complications, hospitalization days and postoperative analgesics use were similar between the 2 study groups. CONCLUSION: LM and LAM is comparable in the perioperative outcomes in patients with symptomatic uterine myoma.

OBJECTIVE: Placental site trophoblastic tumor (PSTT) is the rarest form of gestational trophoblastic disease (GTD) and the optimum management is still controversial. In this study, we analyzed the clinical features, treatment, and outcomes of 6 consecutive patients with PSTT treated in our institution. METHODS: The electronic medical record database of Samsung Medical Center was screened to identify patients with PSTT from 1994 to 2017. Medical records for the details of each patient's clinical features and treatment were extracted and reviewed. This study was approved Institutional Review Board of our hospital. RESULTS: A total of 418 cases of GTD, 6 (1.4%) patients with PSTT were identified. The median age of the patients was 31 years. The antecedent pregnancy was term in all 5 cases with available antecedent pregnancy information and the median interval from pregnancy to diagnosis of PSTT was 8 months. The median titer of serum beta human chorionic gonadotropin (β-hCG) at diagnosis was 190.9 mIU/mL. Five (83.3%) patients presented with irregular vaginal bleeding and one (16.7%) had amenorrhea. All patients had disease confined to the uterus without metastasis at diagnosis and were successfully treated by hysterectomy alone. All of them were alive without disease during the follow-up period. CONCLUSION: In this study, we observed low level serum β-hCG titer and irregular vaginal bleeding with varying interval after antecedent term pregnancy were most common presenting features of PSTT. In addition, we demonstrated hysterectomy alone was successful for the treatment of stage I disease of PSTT.

OBJECTIVE: It is clear that uterine carcinosarcomas and uterine papillary serous carcinomas (UPSC) have an adverse impact on outcome, but whether carcinosarcomas are worse than UPSC is unclear. The purpose of this study is to compare the pathology, survival, and disease recurrence of patients with carcinosarcomas to patients with UPSC. METHODS: The medical records of patients diagnosed with carcinosarcomas and UPSC between 1996 and 2009 at Samsung Medical Center were retrospectively analyzed. Information from pathology reports, site of relapse, time to recurrence, and death was obtained. The survival analysis was performed using the Kaplan-Meier method. RESULTS: Thirty seven patients with carcinosarcomas and 38 patients with UPSC were identified during the study period. There was no significant difference in clinical characteristics including age, body mass index, proportion with advanced stage disease, rate of optimal debulking, and adjuvant treatment used. In addition, the pathology showed no significant difference in tumor size, myometrial involvement, lymphovascular invasion, peritoneal cytology, cervical invasion, and lymph node involvement. Patients with carcinosarcomas had similar patterns of relapse as the patients with UPSC. There was no difference in the progression-free and overall survival between the carcinosarcomas and UPSC patients (p=0.804 and p=0.651, respectively). CONCLUSION: Patients with carcinosarcomas had similar clinicopathological features compared to the patients with UPSC.
