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.

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 p16^INK4a activation due to HPV infection, which is an important factor in the outbreak of cervical cancer, has been highlighted. Recent studies have reported that p16^INK4a 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 p16^INK4a tests on the differential diagnosis of atrophy and ASCUS. This study focused on whether p16^INK4a immunocytochemical staining and HPV tests can help diagnose borderline lesions between atrophy and ASCUS. The results reported that p16^INK4a activation can significantly (P<0.001) differentiate atrophy from ASCUS in atrophic lesions infected with High risk-HPV. Therefore, it may be concluded that p16^INK4a 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.

목적 : 방사선단독으로 치료했던 자궁경부암에서 치료실패 양상과 치료실패에 대한 위험인자를 확인하여 동시항암 화학방사선요법의 적용기준을 마련하고자 본 연구를 시행하였다. 대상 및 방법 : 1989년 4월부터 1997년 12월까지 경상대학교병원 치료방사선과에서 자궁경부암으로 방사선치료를 시행받은 환자중 외부방사선조사와 강내조사를 계획대로 완료한 154명을 대상으로 후향적 분석을 시행하였다. FIGO에 의한 병기별 분포는 Ib 12명, IIa 24명, IIb 98명, IIIa 1명, IIIb 17명, IVa 2명이었다. 생존율은 Kaplan-Meyer 법을 이용하여 구하였고, 생존율의 비교는 Log-rank test로, 다변량분석은 Cox proportional hazard model을 이용하였다. 국소 또는 원격실패에 대한 단변량, 다변량분석은 logistic regression model을 사용하였다. 방광 및 직장의 합병증 평가는 RTOG/EORTC에서 제안하여 사용하고 있는 SOMA scale을 적용하였다. 결과 : 전체 154명 가운데 완전 관해를 보인 경우는 130명으로 완전관해율은 $84.4\%$였다. 완전관해자 가운데 6명이 국소재발, 25명이 원격전이, 10명이 국소재발 및 원격전이를 보여 완전관해자 가운데 $31.5\%$가 치료에 실패하였다. 연구대상 전체의 치료실패양상을 보면 국소실패가 25명, 원격실패가 25명, 국소 및 원격실패가 15명으로 전체환자의 치료실패율은 $42.1\%$ (65/154)였고, 국소실패율(국소단독실패와 국소, 원격 이중실패를 합한 것) 및 원격실패율(원격단독실패와 국소, 원격 이중실패를 합한 것)은 각각 $25.9\%$ (40/154), $25.9\%$ (40/154)였다. 국소실패의 위험인자로서는 단변량, 다변량분석 모두에서 종양의 크기가 유의하였고 원격실패의 위험인자로서는 단변량분석에서는 병리, 종양의 크기, 골반임파절전이, 치료전 혈색소 수치가 유의하였으나, 다변량분석에서는 종양의 크기, 골반임파절전이가 유의하였다. 5년 생존율은 $FIGO\;Ib\;74\%,\;IIa\;67\%,\;IIb\;63\%,\;IIb\;45\%$. 결론 : 종양의 크기가 4 cm 이상인 경우 방사선치료만으로는 국소 및 원격실패의 가능성이 높고 생존율 역시 낮다. 크기가 4 cm 이상이거나 골반임파절전이가 있는 경우 대동맥임파절 전이 가능성이 높다. 따라서 크기가 4 cm 이상이거나 골반임파절 전이가 있는 경우 국소제어율을 높이고 원격전이를 줄이기 위해 동시방사선항암화학요법을 시행하여야 한다.
