Abstract
To explore the risk factors of lung metastasis in patients after laparoscopic radical hysterectomy (LRH) of cervical cancer (CC).The clinical data of CC patients with clinical stage of IA1-IIA2 diagnosed in our hospital from April 2007 to October 2015 were collected. According to the situation of metastasis, the patients were divided into lung metastasis (n = 73) and non-lung metastasis group (n = 2076). The clinical data were compared between 2 groups, and logistic stepwise regression model was used to analyze the risk factors of lung metastasis in patients with CC after LRH.The incidence of lung metastasis after LRH of CC was 3.39%, and 67.13% of patients with lung metastases had no obvious clinical symptoms. 15.06% patients had lung metastasis in the first year, 38.35% in the second year, 43.83% in the third year and later. The postoperative lung metastasis of CC was related to tumor diameter (P < .001), pathological type (P < .001), interstitial invasion depth (P < .001), pelvic lymph node metastasis (PLNM, P < .001), vascular tumor thrombus (P = .011), tumor uterine invasion (P = .002), and abnormal preoperative tumor markers (P = .015). However, it was not related to age, clinical stage, tumor growth pattern, tumor differentiation, and para-aortic lymph node metastasis (P > .05). Logistic regression analysis revealed non-squamous cell carcinoma (P = .022), tumor diameter ≥4 cm (P = .008), interstitial invasion depth >2/3 (P = .003), PLNM (P = .007), and tumor uterine invasion (P = .037) is an independent risk factor for lung metastasis after LRH of CC.Non-squamous cell carcinoma, tumor diameter ≥4 cm, tumor interstitial invasion depth >2/3, PLNM, and tumor uterine invasion are independent risk factors for lung metastasis after LRH of CC.

Abstract
Recent studies assessing the patterns of failure following locoregional definitive therapy suggest that recurrences do happen in the adjacent most proximal drainage sites, not infrequently occurring within the common iliac and para-aortic regions. This pattern of recurrence and identification at initial presentation is being increasingly recognised using novel imaging techniques and there is limited evidence on how to manage these patients. We are awaiting definitive evidence regarding the clinical benefit of whole pelvic radiotherapy, and currently there is no consensus as to the optimal superior border. There is some acknowledgement that the superior border should encompass the common iliac nodal region. However, whether it should be extended even more proximally is currently unknown. Prospective randomised trials are required to determine if there is a role for extending the radiotherapy field in patients with or at high risk of para-aortic metastases.

Abstract
OBJECTIVE This study was conducted to evaluate the efficacy and toxicity of extended-field intensity-modulated radiation therapy combined with concurrent chemotherapy in patients with cervical cancer with positive para-aortic lymph nodes (PALN). METHODS From September 2007 to December 2014, a total of 59 patients who had cervical cancer with para-aortic lymph node metastasis were treated with concurrent chemoradiotherapy at our institution. A dose of 45-50.4 Gy in 25-28 fractions with extended-field intensity-modulated radiation therapy was prescribed to planning target volume, and a dose of 30-36 Gy in 5-6 fractions was prescribed to Point A with high-dose-rate brachytherapy. A concurrent first-line cisplatin-based chemotherapy regimen was used. RESULTS The median duration of follow-up was 32.1 months (range, 3.2-103.7 months). The 2- and 3-year overall survival, disease-free survival and local control rates were 69.0 and 52.8%, 45.0 and 41.3% and 83.4 and 81.0%, respectively. Distant metastasis was the major pattern of treatment failure, which occurred in 26 patients (44.1%). The incidence of Grade 3 or greater acute hematologic, gastrointestinal and genitourinary toxicity was 50.9, 1.7 and 3.4%, respectively. Only one patient had both Grade 3 late gastrointestinal and genitourinary toxicity. CONCLUSIONS The study found that extended-field intensity-modulated radiation therapy combined with concurrent chemotherapy was safe and effective in patients who had cervical cancer with positive PALN.

Abstract
Objective: To identify the predictors of distant metastasis in patients with cervical cancer treated with definitive radiotherapy and develop a model for predicting distant metastasis. Methods: We reviewed the clinical records of patients with cervical cancer treated with definitive radiotherapy (IMRT) at Peking Union Medical College Hospital between January 2011 and December 2015. Eligible patients were randomly assigned into model development cohort and validation cohort in a 2:1 ratio. Distant metastasis rate (DMR) was calculated with Kaplan-Meier method. Univariate and multivariate analyses using cox proportional hazard model was performed to identify the risk factors of distant relapse. Based on the identified risk factors for distant metastasis, a model for predicting distant metastasis was developed and validated. A two-side P<0.05 was defined as statistically significant. Results: A total of 1193 patients were eligible for this analysis including 797 patients in the model development cohort and 396 patients in the validation cohort. The median follow-up durations of the model development cohort and the validation cohort were 28.7 months (range: 2.5-83.9 months) and 30.9 months (1.9-83.5 months). The 2-year distant metastasis rates (DMR) for patients in the model development cohort and validation cohort were 13.3% and 12.8%. Non-squamous cell carcinoma (non-Scc), common iliac lymph nodes metastasis (LNM) and bilateral pelvic LNM (PLNM) were identified as risk factors for distant metastasis. In the model development cohort, significant difference between high-risk group (with 2-3 risk factors) and low-risk group (with 0-1 risk factor) regarding DMR was observed (39.3% vs 19.3%, P<0.001). Similar conclusions were observed in the validation cohort (high-risk group vs low-risk group, 47.6% vs 10.9%, P<0.001) Conclusion: We successfully developed a model for predicting distant metastasis in patients with cervical cancer receiving definitive radiotherapy based on the three identified risk factors for distant metastasis. This model would help us distinguish patients with high risk of distant relapse from others.

Abstract
The aim of the present study was to clarify the feasibility and efficacy of helical tomotherapy during concurrent chemoradiotherapy for treating cervical cancer. The medical records of 13 patients who underwent oncurrent chemoradiotherapy using helical tomotherapy for cervical cancer at Wakayama Medical University Hospital between 2013 and 2015 were retrospectively reviewed. A total of 15 patients who underwent oncurrent chemoradiotherapy using conventional radiotherapy (CRT) between 2008 and 2013 at our institution were also examined for comparison. The median age of patients treated with helical tomotherapy was 60 (range, 35-71), and the median age of patients treated with CRT was 57 (range, 43-77). The median follow-up period was 27 months (range, 3-46) in the tomotherapy group and 35 months (range, 7-88) in the CRT group. The frequency of G3/4 thrombocytopenia in the tomotherapy group was significantly higher than that in the CRT group (P=0.049). However, the platelet count spontaneously recovered without transfusion. There were no significant differences between the groups in terms of frequency of G3/4 neutropenia, diarrhea or late intestine injury. The rate of complete response in the tomotherapy group and the CRT group was 84.6 and 73.3%, respectively, and there was no significant difference in the response rate between the groups. There were no significant differences in the progression-free survival or progression-free rate in the irradiation field between the groups. Adverse events from concurrent chemoradiotherapy using helical tomotherapy were acceptable and clinically controllable. The present results suggest that helical tomotherapy is efficient during concurrent chemoradiotherapy for treatment of advanced cervical cancer.

Abstract
The current standard of care for locally advanced cervical cancer is whole pelvis and para-aortic radiation when indicated, delivered concomitantly with chemotherapy and brachytherapy. Para-aortic node involvement is a predictor of survival in locally advanced disease but presence of metastases is difficult to determine because the currently available imaging methods lack enough sensitivity to be able to detect accurately para-aortic metastases when surgical staging is not feasible. The objective of this review is to describe the current status of para-aortic lymph node irradiation in locally advanced cervical cancer. It includes analysis of the diagnostic imaging and surgical approaches for assessment of para-aortic lymph node dissemination, together with indications for radiotherapy and radiotherapeutic techniques.

Abstract
Pre-B-cell leukemia homeobox 3 (PBX3) is upregulated in various malignancies; however, the role of PBX3 in cervical cancer (CC) is unknown. The purpose of this study was to explore the expression characteristics, clinicopathological significance, and molecular biological function of PBX3 in CC. The expression levels of PBX3 were analyzed in CC cell lines and tumor specimens by real-time polymerase chain reaction (RT-PCR), Western blotting, and immunohistochemical staining. The clinicopathological characteristics associated with PBX3 expression were evaluated. An RNA interference approach was employed to suppress PBX3 expression in CC in vitro and in vivo, determine its role in cell proliferation and analyze its molecular function. We found that PBX3 expression was significantly upregulated in CC cell lines and clinical specimens compared with normal cells and adjacent nontumorous cervical tissues. PBX3 was an independent predictive factor of poor prognosis, and its expression was correlated with tumor diameter, pathological grading, lymph node metastasis, invasion depth, vascular invasion, and clinical stage of CC. Multivariate analysis suggested that PBX3 expression may represent an independent prognostic indicator of the survival of CC patients. CC patients with high PBX3 expression exhibited reduced overall survival compared with those with low PBX3 expression. Additionally, stable downregulation of PBX3 expression in CC cell lines suppressed cell proliferation and decreased p-AKT protein expression levels in vitro. Similarly, in vivo assays demonstrated that PBX3 downregulation in CC cells markedly inhibited tumor size and weight. Overall, we demonstrated that PBX3 can promote CC cell proliferation via the AKT signaling pathway and that it may serve as a prognostic marker. Our data indicate that inactivation of PBX3 may be an effective clinical treatment for CC.
