STUDY DESIGN: A case report. OBJECTIVES: To report a case of indirect repair of cerebrospinal fluid (CSF) leakage after cervical anterior foraminotomy using Surgicel® and fibrin glue. SUMMARY OF LITERATURE REVIEW: There is no single modality that is best practice for this type of case because it is difficult to apply primary repair for a case of CSF leakage after cervical anterior decompression. MATERIALS AND METHODS: A 49-year-old female patient was diagnosed with CSF leakage on the second day after cervical anterior foraminotomy. We performed coverage with Surgicel® and fibrin glue at the CSF leak site. RESULTS: The patient was treated with indirect repair of CSF leakage without any complications. The clinical and radiological outcomes were excellent upon follow-up 1 year postoperatively. CONCLUSIONS: Indirect repair using Surgicel® and fibrin glue is an effective treatment for postoperative CSF leakage after cervical anterior foraminotomy.

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: Galectin-3, a member of the beta-galactoside-binding proteins, is an intracellular and extracellular lectin that interacts with intracellular glycoproteins, cell surface molecules and extracellular matrix proteins. Galectin-3 is expressed widely in epithelial and immune cells and the level of expression varies in many cancer cells relative to the normal tissues from which they arise. We investigated whether the expression of galectin-3 is associated with the progression of cervical neoplasia. METHODS: The galectin-3 expression was evaluated by immunohistochemistry in 90 formalin-fixed paraffin-embedded cervical tissues: 10 normal cervical specimens, 20 low-grade squamous intraepithelial lesions (LSILs), 20 high-grade squamous intraepithelial lesions (HSILs), and 40 invasive squamous cell carcinomas (ISCCs). RESULTS: The immunohistochemical staining showed that the expression of galectin-3 was strong in all normal cervical squamous epithelia. Staining gradually decreased in accordance with the histopathologic grades from an LSIL to an HSIL and an ISCC (P<0.001). In particular, the expression of galectin-3 was significantly decreased in HSILs (P=0.001) and this down-regulation was more pronounced in ISCCs than normal tissues (P<0.001). CONCLUSION: These data constitute the first observation that the expression of galectin-3 is down-regulated in cervical cancer tissues and suggest the decreased expression of this galactoside-binding lectin is associated with the progression of cervical neoplasia.

OBJECTIVE: To compare laparoscopic surgery with conventional abdominal surgery in patients with early stage endometrial cancer. METHODS: A retrospective review of 63 patients with early stage endometrial cancer managed between March 2003 and May 2005. Two groups were defined whether they had been treated by laparoscopy (case group: n=26) or by laparotomy (control group: n=37). We compared age, body mass index (BMI), hemoglobin change, operation time, number of pelvic lymph nodes, hospital stay, case with adjuvant treatment and recurrence between two groups. RESULTS: There was no statistical difference in characteristics (age, BMI, nulliparity, previous abdominal surgery, FIGO stage, histologic grade). between case and control group. In addition, there was no statistical difference in operation data and outcomes between two groups. Hemoglobin changes were 1.1 g/dL (case group) vs 1.7 g/dL (control group) (p=0.072). Operation time was 131 min vs. 115 min. The numbers of lymph nodes obtained were 8.7 vs 7.7 (right) 9.2 vs. 7.6 (left). Hospital stays were 8.4 vs. 9.2 days. Adjuvant treatment cases were 7 vs. 15. Recurrent case was one in each group. Two patients initially evaluated by laparoscopy were converted to laparotomy due to bleeding and adhesion. CONCLUSION: Laparoscopic surgery for treatment of early endometrial cancer is a safe and effective alternative to laparotomy . However, long-term survival and risk of recurrence have yet to be determined.

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: This study was to determine the expression of Toll-like receptor 4 (TLR-4) in ovarian serous adenocarcinoma tissues. METHODS: TLR-4 expression was evaluated at the RNA level by real-time quantitative RT-PCR, in 24 fresh frozen ovarian serous adenocarcinoma tissues and 9 normal ovarian tissues. TLR-4 expression was also evaluated by immunohistochemistry (IHC) in each three ovarian carcinoma tissues and normal ovarian tissues. RESULTS: Positive immunoreactivity for TLR-4 was observed in the normal ovarian tissues but not in the ovarian carcinoma tissues. The staining was localized in the cytoplasm as well as on the cell surface. Real-time quantitative RT-PCR revealed that TLR-4 expression was significantly lower in tumors than in normal ovarian tissues (p=0.0003). There were no significant correlations between clinical parameters and the expression level of TLR-4 mRNA in ovarian serous adenocarcinomas. However, tumors without LN metastasis (p=0.068) and lower grade (p=0.075) showed trends of higher TLR-4 mRNA expression. CONCLUSION: TLR-4 expression was significantly lower in ovarian serous adenocarcinoma tissues than in normal ovarian tissues, and further studies on TLR-4 signaling pathway in ovarian carcinoma are needed.

OBJECTIVE: Tissue inhibitors of metalloproteinases (TIMPs) play a key role in maintaining homeostasis of the extracellular matrix (ECM) by controlling matrix metalloproteinases (MMPs). In addition to their role in regulating MMPs, TIMPs have also been shown to have pluripotential effects on cell growth, apoptosis and differentiation. The aim of this study was to examine TIMP-2 level in serous ovarian tumor tissues and to understand further the role of TIMP-2 protein in ovarian tumorigenesis. METHODS: Expression of TIMP-2 was assessed by immunohistochemistry in a total of 57 ovarian specimens including five normal ovaries, 12 benign serous cystadenomas, 20 serous borderline tumors and 20 serous carcinomas. RESULTS: The present study found that TIMP-2 immunostaining was significantly more frequent in serous carcinomas, mainly in tumor epithelium, compared with cells of the other tissues studied. CONCLUSION: TIMP-2 in serous ovarian carcinoma may function to favor tumor growth in serous ovarian tumorigenesis. Additional research is now needed to elucidate further the role of TIMP-2 in the biological behavior of ovarian serous tumors.
