Radical trachelectomy is a fertility-preserving alternative to radical hysterectomy in carefully selected young women with early-stage cervical cancer. However, in cases with subsequent severe cervical stenosis, assisted reproductive techniques can be difficult. This is a case report of a 34-year-old patient who underwent robot-assisted radical trachelectomy and cerclage for early-stage (IB2) adenosquamous carcinoma. Three months after surgery, the patient underwent ovarian stimulation using a gonadotropin-releasing hormone antagonist protocol. As it was impossible to perform transcervical embryo transfer due to the almost complete absence of the cervical opening, transmyometrial embryo transfer under ultrasound guidance was performed. This resulted in a successful singleton pregnancy. This is the first case of successful pregnancy conceived by in vitro fertilization with transmyometrial embryo transfer in a patient who had previously undergone robot-assisted radical trachelectomy.

A total of 285 patients with stage Ib2 and IIa2 cervical cancer were categorized into three groups, and received preoperative neoadjuvant chemotherapy combined with vaginal intracavitary irradiation, neoadjuvant chemotherapy alone or radiotherapy, respectively. The effective rate of 70.6 % in group 1 was much higher than 41.4% in group 2 (P=0.000) and 46.9 % in group 3 (P=0.000); The percentage of patients receiving postoperative adjuvant therapy was 44.1% in group 1, much lower than 67.8% in group 2 (P=0.001) and 64.6% in group 3 (P=0.004); The percentage of patients with no postoperative risk factor in group 1 was 52.0%, much higher than 32.2% in group 2 (P=0.006) and 35.4% in group 3 (P=0.019); The occurrence rate of surgery-related complications in groups 1, 2 and 3 were 29.4%, 28.7%, and 33.3%, respectively, with no statistical differences among the groups (P=0.981). Regarding preoperative neoadjuvant complications, none were obvious in group 3, while occurrence rates of myelosuppression in groups 1 and 2 were 89.1% and 86.6%, of nausea and vomitting were 78.4% and 78.2%, but without significant differences (all P>0.05). Among 166 patients who received postoperative adjuvant therapy in the three groups, the occurrence rates were: 65.4%, 64.3% and 61.1% respectively for myelosuppression; 42.3%, 38.1%, and 38.9% for nausea and vomiting; 9.6%, 9.5% and 9.7% for urocystitis; and 63.5%, 69.0% and 65.3% enteritis and rectitis. There were no statistically significant differences among them (all P>0.05). The five-year disease-free survival rates (DFS) in groups 1, 2, 3 were 78.3%, 75.1%, 80.9%, respectively; the five-year overall survival rates (OS) were 81.4%, 78.2%, and 81.1%, respectively. The five-year OS of 166 patients receiving postoperative in the three groups were 72.4%, 69.5%, and 71.8%, respectively, with no significant variation (all P>0.05). Although there were no differences among three groups in DFS and OS, preoperative neoadjuvant chemotherapy combined with intracavitary radiotherapy may increase the effective rate and the percentage of patients with no postoperative risk factors and decrease the percentage of patients receiving postoperative adjuvant therapy, thereby decreasing complications indirectly and increasing quality of life.

This is a retrospective analysis of 64 patients who was treated with postoperative radiation therapy after radical hysterectomy and bilateral pelvic lymphadenectomy (53 patients) or total abdominal hysterectomy(11 patients) for uterine cervix cancer between May 1980 and September 1991 at the Department of Radiation Oncology, Kyung Hee University Hospital. Most patients were FIGO IB (31 Patients) and IIA (25 patients), and median period of follow-up was 5.1 years. Of these patients,24 received adjuvant whole pelvis irradiation of 6000 cGy and 40 received 5000-5500 cGy whole pelvis irradiation and/or intracavitary radiation (7 Patients). The actuarial overall and relapse free 5 year survival rate were $71.0\%$, $68.3\%$ respectively. The survival rates by stage were $79.1\%$ in stage I, and $61.2\%$ in stage II. Treatment failure was noted in 18 of 64 patients ($28.1\%$), Iocoregional failure in 8 ($12.5\%$), distant metastasis in 8 ($12.5\%$), paraaortic node metastasis in 1 and one patient and concurrent locoregional and distant metastasis. The univariate analysis of prognostic factors affecting to overall survival rate represented lymph node status, the number and site of metastatic lymph node, parametrial invasion, the thichness of cervical wall invasion, and size of cancer mass. Histology, vessel invasion, endometrial extension, hemoglobin level. resection margin status, age, radiation dose were not significant prognostic factors. Complication relating to operation and postoperative radiation were variable according to radiation therapy method: 6000 cGy RT group 8/24($33.3\%$), 5000-5500 cGy+ICR 3/7 ($42.9\%$), 5000-5500 cGy external RT only group 3/33 ($9.1\%$). In conclusion, the results suggest that postoperative radiotherapy is necessary in high risk patients for locoregional control and improving survival rate, and higher dose does not improve results but only increases complication.

Background: The tumor-stroma ratio (TSR) represents the percentage of neoplastic cell components compared to the combined area of neoplastic cells and the surrounding tumor-induced stroma. A low TSR (predomination of stromal component) has been demonstrated to be an independent adverse prognostic factor in cancers of several organs. In cervical carcinoma patients, TSR has been evaluated in only one previous study with different histological types. The present study aimed to assess the prognostic value of TSR in early stage cervical cancer patients with adenocarcinoma histology only. Materials and Methods: Histological slides of patients with early stage (IB-IIA) cervical adenocarcinoma who underwent surgical treatment between January 2003 and December 2011 were reviewed. Patients who had received preoperative chemotherapy were excluded. TSR was categorized as low (<50%) and high (${\geq}50%$). Correlations between TSR and clinicopathological variables were evaluated. Prognostic values of TSR and other variables were estimated using Cox's regression. Results: Of 131 patients; 38 (29.0%) had low TSR and 93 (71.0%) had high TSR. The patients with low TSR had significantly higher proportions of deep cervical stromal invasion (outer third of wall, p=0.011; residual stroma less than 3 mm, p=0.008) and parametrial involvement (p=0.026). Compared to the patients with high TSR, those with low TSR tended to have lower 5-year disease-free survival rate (83.8% versus 88.9%) and overall survival rate (85.6% versus 90.3%), although the differences were not statistically significant. Low TSR was significantly associated with decreased overall survival in univariate analysis (HR 2.7; 95% CI 1.0-7.0; p=0.041), but not in multivariate analysis. TSR was not significantly associated with decreased disease-free survival. Conclusions: Low TSR is associated with decreased overall survival in patients with early stage cervical adenocarcinoma treated by surgery. However, it was not found to be an independent prognostic predictor in this study.

Background: This study aimed to determine the utility and a cut-off level of serum squamous cell carcinoma antigen (SCC-Ag) to predict lymph node metastasis in locally advanced cervical cancer cases. We also investigated the correlation between SCC-Ag level and lymph node status. Materials and Methods: From June 2009 to June 2014, 232 patients with cervical cancer stage IB2-IVA, who were treated at Ramathibodi Hospital, were recruited. Receiver operating characteristic (ROC) curves were used to identify the best cut-off point of SCC-Ag level to predict lymph node metastasis. Quantile regression was performed to evaluate the correlation between SCC-Ag levels and pelvic lymph node metastasis, paraaortic lymph node metastasis, and parametrial involvement as well as tumor size. Results: Pelvic lymph node metastasis and paraaortic lymph node metastasis were diagnosed in 46.6% and 20.1% of the patients, respectively. The median SCC-Ag level was 6 ng/mL (range, 0.5 to 464.6 ng/mL). The areas under ROC curves between SCC-Ag level and pelvic lymph node metastasis, paraaotic lymph node metastasis, parametrial involvements were low. SCC-Ag level was significantly correlated with paraaortic lymph node status (p=0.045) but not with pelvic lymph node status and parametrial involvement. SCC-Ag level was also related to the tumor diameter (p<0.05). Conclusions: SCC-Ag level is not a good predictor for pelvic and paraaortic lymph node metastasis. However, it is still beneficial to assess the tumor burden of squamous cell carcinoma of the cervix.

We conducted a retrospectively reviewed of the literature published of patients underwent fertility-preserving treatments for cervical, endometrial and ovarian cancers using the WANFANG database in Chinese. A majority were retrospective studies and case reports. With cervical cancer, radical trachelectomy(RT) in combination with pelvic lymphadenectomy could preserve the fertility of patients with early stage IA1-IB1 cancers, Tumor size ${\leq}2cm$ should be emphasized as the indication of RT in considering of the higher recurrent rate in patients with tumor size >2cm. For endometrial cancers, there is much experience on it. Given accurate pretreatment assessment, hormonal therapy is feasible management option to preserve fertility in young patients with early stage lesions that limited to the endometrium and well differentiated. High dose progestin have been applied, oral medroxyprogesterone acetate (MPA), 250-500mg/day, megestrol acetate 160-480mg/day. Other therapies that have been used in a limited number of cases include GnRH analog, intrauterine devices (IUDS) containing progestogen, usually combination of these therapies. All patients should be followed up by ultrasound and/or MRI evaluation, and endometrial curettage at intervals of 3 months. With ovarian cancer, in China, fertilitypreserving surgery in patients with stage IA (grade G1) of epithelial ovarian tumor and patients with germ cell tumor and borderline ovarian tumor have been successfully performed.

목적: 자궁경부암에서 수술 후 위험인자가 있는 환자에 방사선치료 후 생존율, 국소 제어율과 예후인자를 후향적으로 분석하여 수술 후 방사선치료의 효과를 알고자 한다. 대상 및 방법: 1986년 3월부터 1998년 12월까지 자궁경부암 FIGO 병기 IB-IIB로 자궁적출술 후 방사선치료를 받은 58명을 대상으로 국소 제어율, 5년 무병생존율과 생존율에 미치는 예후인자를 후향적으로 분석하였다. 수술 후 방사선치료의 적응증은 병리학적으로 림프절에 전이된 경우, 암이 수술절제연이나, 자궁주위조직 혹은 자궁체부에 침범하였거나, 림프혈관강에 침범된 경우, 자궁기질의 1/2 이상 깊이 침윤된 경우와 단순 자궁적출술 후 암으로 진단받은 환자로 하였다. 수술 후 방사선치료는 모든 환자에서 골반강에 외부조사를 시행하였으며 5명은 외부조사와 강내조사를 병용하였다. 외부조사는 6 MV x-선을 이용하여 매일 180 cGy를 4문으로 조사하였으며 총 방사선량은 $4400\~5040$ cGy (중앙값: 5040 cGy)이었다. 강내조사는 외부조사 후 2주에 Cs-137를 이용하여 저선량률로 질 표면에서 5 mm 깊이에 $4488\~4932$ cGy (중앙값: 4500 cGy)를 시행하였다. 추적기간은 15개월에서 108개월로 중앙값은 44개월 이었다. 결과: 전체환자의 5년 무병생존율은 $94\%$, 국소 제어율은 $98\%$,이었으며 원격 전이율은 $5\%$이었다. 병기에 따른 5년 무병생존율은 $IB\;97.1\%,\;IIA\;100\%,\;IIB\;68.9\%$(p=0.0145)이었다. 질 절제연에 암의 침범이 없는 경우 5년 무병생존율이 $97.8\%$, 있는 경우 $60\%$, (P=0.0002)이었으며, 자궁주위조직에 암이 침범이 없는 경우의 5년 무병 생존율은 $97.8\%$이었고, 있는 경우는 $33.3\%$이었다(p=0.0001). 다변량 분석에 의하면 자궁주위조직의 침범만이 통계학적으로 의의있는 예후인자이었다. 치료 후 만성합병증은 3명($5\%$,)에서 RTOG grade 2의 방광염, 1명에서 grade 2의 직장염과 1명에서 하지에 림프부종이 나타났다. 결론: 조기 자궁경부암 환자에 단순 자궁적출술을 시행하였거나, 근치적 자궁적출술 후 병리학적으로 재발 위험 인자가 있는 환자에 수술 후 방사선치료를 시행하여 심각한 부작용 없이 비교적 높은 국소 제어율과 생존율을 얻을 수 있었다. 생존율에 영향을 미치는 예후인자는 병리학적으로 암이 자궁주위조직에 침범된 것으로 예후가 불량하였다. 수술 후 방사선치료의 실패원인과 예후인자를 분석한 본 후향적 연구결과를 토대로 앞으로 방사선치료와 항암화학요법을 병용하여 보다 적극적이고 전향적인 연구를 시도하는데 이정표로 이용할 수 있다고 생각한다.

목적 : 종양의 크기가 5cm 이상인 병기 Ib, IIa와 IIb 자궁경부암 환자에서 다분할 외부방사선 치료와 강내 치료의 효과를 알아 보기 위해 본 연구를 시행하였다. 재료 및 방법 : 1991년 7월부터 1994년 4월까지 계명대학교 동산의료원 치료방사선과에서 다분할 방사선치료를 받은 자궁경부암환자 41명을 대상으로 하였다. 환자의 분포는 종양의 크기가 5cm 이상의 병기 Ib, IIa가 각각 3명, 6명, 병기 IIb가 32명이었고 평균연령은 55세이었다. 방사선 치료는 외부방사선치료로 전골반강에 하루에 120cGy를 2회(최소 5시간 같격) 조사하여 3600-5520cGy 조사하고 양측자궁경관주위에 조사량이 4480-6480cGy 되도록 4x loom 중간차폐를 하여 조사한 후 A 지점에 전체 조사량이 Ib,IIa에는 7480-8520cGy, IIb에는 8480-9980cGy 되도록 강내조사를 시행하였다. 최장기 및 중앙 추적기간은 각각 70개월, 47개월이었다. 통계적으로 생존률과 단일변수분석은 각각 Kaplan-Myer법과 Log-rank 법을 이용하였다. 결과: 5년 국소제어률은 $78\%$이었고 5년 생존률은 전체환자에서 $66.1\%$이였었고 병기 Ib, IIa 에서 $44.4\%$, 병기 IIb에서 $71.4\%$이었다. 종양의 크기가 5cm 이상인 IIb(11명)에서 5년 국소제어률과 5년생존률이 각각 $88.9\%,\;73\%$이었다. 5년 생존률이 림프절전이 유무에 따라 $74\%\;vs\;25\%$(P=0.0015)로 유의하게 차이가 있었다. A 지점의 선량(84Gy 이상 vs 840y 이하)에 따른 생존률의 차이는 $70\%\;vs\;42.8\%$(P=0.1)로 나타났으며 병기 Ib,IIa에서 IIb보다 낮은 국소제어률과 생존율을 보인 것은 A 지점의 평균 선량이 Ib, IIa에서는 79Gy, IIb에서는 89Gy로 유의한 차이가 나는 것이 요인이 될 것으로 사료된다. 전체 재발률은 $39\%$(16/41)이었고 국소재발이 $14\%$(6/41) 원격전이가 $19.5\%$(8/41) 동시재발이 $4.8\%$(2/41)이었다. 부작용으로는 급성 3도 위장관계 부작용이 3명 $(7.3\%)$에서 있었고 3도의 백혈구 감소증이 2명$(4.9\%)$에서 있었으며 3도 이상의 만성 부작용은 없었고 치료에 의한 사망은 없었다. 결론 :다분할 방사선 치료시 종양의 크기가 큰 Ib,IIa에서는 A지점의 방사선량을 85Gy 이상으로 높일 필요가 있을 것으로 사료되며 종양의 크기가 5cm 이상의 병기 IIb인 자궁경부암 환자에서 다분할 방사선치료와 근접방사선치료는 심각한 합병증 없이 시행될 수 있을 것으로 생각되며 생존률의 향상을 기대할 수 있을 것으로 사료되나 환자의 수가 적으므로 더 많은 환자를 대상으로 장기간의 추적을 통해 검증되어야 할 것으로 생각된다.

Background: The research was to compare the efficacy and side effects of cisplatin or lobaplatin in combination with mitomycine (MMC) and vincristine in treating patients with cervical squamous carcinoma. Materials and Methods: Cervical squamous carcinoma patients who were pathologically diagnosed with stage Ib-IIb from April 2012 to May 2013 in the general hospital of Chinese People's Libration Amy were enrolled. All patients were confirmed without prior treatment and were randomly divided into two groups, Group A and B. Efficacy and side effects were evaluated after one cycle of chemotherapy. Results: Group A (n=42) were treated with Loubo$^{(R)}$ (Lobaplatin) $50mg/m^2$, MMC $16mg/m^2$ and Vincristine $2mg/m^2$ every 21 days. Group B (n=44) were treated with Cisplatin $100mg/m^2$, MMC $16mg/m^2$ and Vincristine $2mg/m^2$ every 21 days. All 86 patients completed one cycle of chemotherapy with cisplatin or lobaplatin in combination with MMC and vincristine. No difference was observed regardiing short-term effect between two groups. Main side effects were bone marrow suppression and gastrointestinal reactions including decrease of white blood cells, platelet and nausea/vomiting. Grade III-VI liver and kidney impairment was not reported in two groups. In group A the incidence of uterine artery spasm in the process of drug delivery was significantly lower than the group B. Conclusions: Cisplatin or lobaplatin with MMC and Vincristine in the interventional treatment of cervical squamous carcinoma were effective, especially after uterine artery perfusion chemotherapy at tumor reduction and tumor downstaging period. The adverse reactions of concurrent chemotherapy are tolerable, and low physical and mental pressure even more less stimulation of vascular in treatment with lobaplatin. However, the long-term effects of this treatment need further observation.
