Background: Approximately 100,000 women are diagnosed with cancer each year in Korea. According to a survey by the Korean central cancer registry in 2016, uterine cervical cancer, uterine corpus cancer, and ovarian cancer were the 5th, 7th, and 8th most prevalent cancers respectively among Korean women. The present study aims to review the clinico-pathologic characteristics of patients who were treated for major gynecological malignancies at Yeungnam University Medical Center. Methods: Patients with invasive gynecological cancers from January 2012 to February 2019 were retrospectively identified. We analyzed the clinical features, demographic profiles, pathologic data, treatment modality used, adjuvant treatment used, complications, recurrence, and survival outcomes. Results: A total of 287 patients (cervical cancer 115; corporal cancer 86; and ovarian, tubal, or primary peritoneal cancer 90) were included. Most cervical (82.7%) and corporal cancers (89.5%) were diagnosed in the early stages (stage I or II), while more than half (58.9%) the cases of ovarian, tubal or peritoneal cancers were diagnosed in the advanced stages (stage III or IV). Surgical complications were observed in 12.2% of cervical cancers, 16.3% of uterine corpus cancers, and 11.1% of ovarian, tubal, and peritoneal cancers, respectively. The 5-year overall survival rate was 94.1%, 91.0%, and 77.1% for cervical, corporal, and ovarian, tubal, or peritoneal cancers, respectively. Conclusion: Surgical treatment was satisfactory in terms of the incidence of complications, and survival outcomes were generally good. Clinicians should be aware of the clinical and histopathological characteristics of patients with gynecological cancers to be able to provide optimal strategies and counseling.
This article reviewed new trends and controversial issues, including the intensification of chemotherapy and recent brachytherapy (BT) advances, and also reviewed recent consensuses from different societies on the management of locally advanced cervical cancer (LACC). Intensive chemotherapy during and after radiation therapy (RT) was not recommended as a standard treatment due to severe toxicities reported by several studies. The use of positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) for pelvic RT planning has increased the clinical utilization of intensity-modulated radiation therapy (IMRT) for the evaluation of pelvic lymph node metastasis and pelvic bone marrow. Recent RT techniques for LACC patients mainly aim to minimize toxicities by sparing the normal bladder and rectum tissues and shortening the overall treatment time by administering a simultaneous integrated boost for metastatic pelvic lymph node in pelvic IMRT followed by MRI-based image guided adaptive BT.
The challenging clinical outcomes associated with advanced cervical cancer underscore the need for a novel therapeutic approach. Monensin, a polyether antibiotic, has recently emerged as a promising candidate with anti-cancer properties. In line with these ongoing efforts, our study presents compelling evidence of monensin's potent efficacy in cervical cancer. Monensin exerts a pronounced inhibitory impact on proliferation and anchorage-independent growth. Additionally, monensin significantly inhibited cervical cancer growth in vivo without causing any discernible toxicity in mice. Mechanism studies show that monensin's anti-cervical cancer activity can be attributed to its capacity to inhibit the Wnt/β-catenin pathway, rather than inducing oxidative stress. Monensin effectively reduces both the levels and activity of β-catenin, and we identify Akt, rather than CK1, as the key player involved in monensin-mediated Wnt/β-catenin inhibition. Rescue studies using Wnt activator and β-catenin-overexpressing cells confirmed that β-catenin inhibition is the mechanism of monensin's action. As expected, cervical cancer cells exhibiting heightened Wnt/β-catenin activity display increased sensitivity to monensin treatment. In conclusion, our findings provide pre-clinical evidence that supports further exploration of monensin's potential for repurposing in cervical cancer therapy, particularly for patients exhibiting aberrant Wnt/β-catenin activation.

Gastric metastasis (GM) from cervical cancer is extremely rare, and only a few cases have been reported in the English literature. Gastric-type mucinous adenocarcinomas (GAS) of the uterine cervix are rare. GAS is an aggressive cancer commonly found in advanced stages; however, GM has not been reported. This study presents a rare case of GM from GAS of the uterine cervix in a 61-year-old female and describes the radiological findings of both the GM and cervical mucinous adenocarcinoma. GM appeared as a poor enhancing submucosal mass. The cervical mucinous adenocarcinoma appeared as an infiltrating mass with poor contrast enhancement. It exhibited mildly high and low signal intensities on the diffusion-weighted image and apparent diffusion coefficient map, respectively. This case is extremely rare and challenging to diagnose; however, if cervical cancer is an human papillomavirus-independent GAS type and a submucosal lesion is found in the stomach, the possibility of metastasis with a pattern similar to our case could be considered.
Purpose : Despite a development of therapeutic machines and advance in modern radiation therapy techniques, locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate, Combination of chemotherapy and radiotherapy demonstrated benefit in improving local control and possibly the overall survival. Our study was performed to evaluate effect of concurrent chemoradiation on locally advanced uterine cervical cancer. Methods and Materials : Twenty six patients with locally advanced stage(FIGO stage IIB with ${\geq}5cm$ in diameter, III, IVA) were treated with combination of radiation therapy and concurrent cisplatinum between May of 1988 and September of 1993 at our hospital. Radiation therapy consisted of external irradiaton and 1-2 sessions of intracavitary irradiation. Cisplatinum was administered in bolus injection of 25mg/$m^2$ at weekly intervals during the course of external radiation therapy. Results : Of the 26 Patients, twenty-five patients were evaluable for estimation of response. Median follow-up period was 25 months with ranges from 3 to 73 months. Stage IIB, III, and IVA were 16, 5, 4 patients, respectively, Twenty patients were squamous cell carcinoma. Response was noted in all 25 patients: complete response(CR) in 17/25($68\%$), Partial response(PR) in 8/25($32\%$). Of the 24 patients except one who died of sepsis at 3 months follow-up, seventeen patients($70.8\%$) maintained local control in the pelvis: 16/17($94.1\%$) in CR, 1/17($14.3\%$) in PR. Fourteen of the 17 patients with CR are alive disease free on the completion of follow-up. Median survival is 28 months for CR and 15 months for PR. Analysis of 5-year survival by stage shows 11/16($59.8\%$) in IIB, 3/5($60.0\%$) in III, and 1/4($25.0\%$) in IVA. Overall 5-year survival rate was $55.2\%$. Ten patients recurred: 4 at locoregional, 3 in distant metastasis and 3 with locoregional and distant site. Toxicity by addition of cisplatinum was not excessive. Conclusion : Although the result of this study was obtained from small number of patients, it is rather encouraging in view of markedly improved response rate compared with the results of historical group.
A Pap smear is the most important screening test for the diagnosis of cervical cancer. However, subjective judgment by the operator cannot be excluded, and replicability may greatly be reduced if uncertain specimens are examined. Examiners often experience difficulties in differentiating atrophy with inflammatory changes and ASCUS when diagnosing squamous epithelial lesions from a pap smear. Reports often vary between cytologists and pathologists, and misdiagnosis may result in delayed follow-ups and advanced diseases. Hence, auxiliary examinations are necessary when confusing results between atrophy and ASCUS are obtained. The importance of p16INK4a activation due to HPV infection, which is an important factor in the outbreak of cervical cancer, has been highlighted. Recent studies have reported that p16INK4a immunocytochemical staining and HPV high-risk type tests using liquid-based cervical specimens are effective to detect the presence of lesions of grade HSIL or higher in patients with ASC-H. However, no research exists on the utility of HPV and p16INK4a tests on the differential diagnosis of atrophy and ASCUS. This study focused on whether p16INK4a immunocytochemical staining and HPV tests can help diagnose borderline lesions between atrophy and ASCUS. The results reported that p16INK4a activation can significantly (P<0.001) differentiate atrophy from ASCUS in atrophic lesions infected with High risk-HPV. Therefore, it may be concluded that p16INK4a immunocytochemical staining is an effective auxiliary test in lesions infected with HR-HPV when atrophic lesions are difficult to differentiate by morphology. Such results are expected to help decide on adequate follow-up and treatment.

Background: This study aimed to assess the in-field lymph node (LN) failure rate according to LN size and to investigate effect of LN size on the survival outcome of patients with locally advanced cervical carcinoma treated with concurrent chemoradiotherapy (CCRT). Methods: A total of 310 patients with locally advanced cervical carcinoma treated with CCRT were enrolled in retrospective study. LN status was evaluated by magnetic resonance imaging. All patients received conventional external beam irradiation and high-dose rate brachytherapy, and concurrent cisplatin-based chemotherapy. In-field LN failure rate according to LN size was analyzed. Results: The median follow-up period was 83 months (range, 3-201 months). In-field LN failure rate in patients with pelvic LN size more than 10 mm was significantly higher than that in patients with pelvic LN size less than 10 mm (p<0.001). A similar finding was observed in the infield para-aortic LN (PALN) failure rate (p=0.024). The pelvic and PALN size (${\geq}10mm$) was a significant prognostic factor of overall-survival (OS) and disease-free survival rate in univariate and multivariate analyses. The OS rate was significantly different between groups according to LN size (<10 mm vs. ${\geq}10mm$). Conclusion: A LN of less than 10 mm in size in an imaging study is controlled by CCRT. On the other hand, in LN of more than 10 mm in size, the in-field LN failure rate increase and the prognosis deteriorate. Therefore, a more aggressive treatment strategy is needed.
Purpose : This is retrospective study to compare the results of radiation therapy alone and neoadjuvant chemotherapy and radiation in advanced stage of uterine cervical cancer. Materials and Methods : Seventy-six Patients who were treated with definitive radiation therapy for locally advanced cervical cacinoma between June 1988 and December 1993 at the department of radiation oncology, Keimyung University Dong-san Hospital. Thirty six patients were treated with radiation therapy alone and forty patients were treated with cisplatin based neoadjuvant chemotherapy and radiation therapy. According to FIGO staging system. there were 48 patients in stage IIb, 3 patients in stage IIIa, 23 patients in stage lIIb and two patients in stage IVa with median age of 53 years old. Follow-up periods ranged from 7 to 95 months with median 58 months. Results : Complete response (CR) rate were $86.1\%$ in radiation alone group and $80\%$ in chemoradiation group. There was no statistical difference in CR rate between the two groups. Overall five-year survival rate was $67.3\%$. According to stage, overall five-rear survival rates were $74\%$ in stage IIb, $66.7\%$ in stage IIIa, $49.8\%$ in stage IIb, $50\%$ in stage IVa. According to treatment modality overall five year survival rates were $74.1\%$ in radiation alone and $61.4\%$ in chemoradiation group (P=0.4) Five rear local failure free survival rates were $71.5\%$ in radiation alone group and $60\%$ in chemoradiation group (P=0.17). Five year distant metastasis free survival rates were $80.7\%$ in radiation aione group and $89.9\%$ in chemoradiation group (P=0.42). Bone marrow suppression (more than noted in 3 cases of radiaion alone group and 1 case of chemoradiation group. Grade II retal complication was noted in 5 patients of radiation group and 4 patients In chemoradiation group. Bowel obstruction treated with conservative treatment (1 patient) and bowel perforation treated with surgery (1 patient) were noted in radiation alone group. There was no statistical difference in complication between two groups. Conclusion : There was no statistical difference in survival, failure and complication between neoadjuvant chemotherapy and radiation versus radiation alone in locally advanced uterine cervical carcinoma.
Purpose : The aim of this study is to analyze the treatment failure patterns and the risk factors for locoregional or distant failure of uterine cervical carcinoma treated with radiation therapy. Materials and methods . A retrospective analysis was undertaken of 154 patients treated with curative radiation therapy in Gyeongsang National University Hospital from April 1989 through December 1997. According to FIGO classification, 12 patients were stage IB, 24 were IIA, 98 were IIB, 1 were IIIA, 17 were IIIB, 2 were IVA. Results : Overall treatment failure rate was $42.1\%$ (65/154), and that of complete responder was $31.5\%$ (41/130). Among 65 failures, 25 failed locoregionally, another 25 failed distantly, and 15 failed locoregionally and distantly. Multivariate analysis confirmed tumor size (>4 cm) as risk factor for locoregional failure, and tumor size (>4 cm), pelvic lymph node involvement as risk factors for distant failure. Conclusion : On the basis of results of our study and recent published data of prospective randomized study for locally advanced uterine cervical carcinoma, we concluded that uterine cervical carcinoma with size more than 4 cm or pelvic lymph node involvement should be treated with concurrent chemoradiation.

We investigated the usefulness of tumor-associated antigen (TA-4) by a radioimmunoasay method in estimating the extent of disease and tracking the clinical course of disease in 58 patients with cervical cancer. According to our results and those of other authors, the normal range of serum TA-4 was arbitrarily taken to be less than 2 ng/ml. The proportion of the pretreatment positive serum TA-4 level of 48 squamous cell carcinoma patients was $60\%.$ And $40\%$ in 5 adenocarcinoma patients. Advanced disease group showed higher incidence of positive serum TA-4 level; $40\%,\;72\%,\;63\%,\;and\;100\%$ in stage I to IV, respectively. And the absolute values of TA-4 were higher in advanced disease. In patients treated with radiation, elevated serum TA-4 level usually declined after 3000 cGy and further dropped to normal range in $44\%$ after 5000 cGy. The positive rate in primary cervical cancer was $59\%,$ (32/54) and $100\%$ (4/4) in recurrent conical cancer. And 15 patients with recurrent or persistent disease during follow-up revealed $80\%$ positive serum TA-4 level. In conclusion, it would be suggested that serial serum TA-4 measurements may be helpful in tracking the clinical course during and after treatment.
