Liu Y, Zhang N, Yang Q. Predicting the recurrence of usual-type cervical adenocarcinoma using a nomogram based on clinical and pathological factors: a retrospective observational study. Front Oncol 2024; 14:1320265. [PMID: 38384815 PMCID: PMC10879399 DOI: 10.3389/fonc.2024.1320265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 01/16/2024] [Indexed: 02/23/2024] Open
Abstract
Background Usual-type cervical adenocarcinoma is the most frequent type of adenocarcinoma, and its prevalence is increasing worldwide. Tumor recurrence is the leading cause of mortality; therefore, recognizing the risk factors for cervical cancer recurrence and providing effective therapy for recurrent cervical cancer are critical steps in increasing patient survival rates. This study aimed to retrospectively analyze the clinicopathological data of patients with usual-type cervical adenocarcinoma by combining the diagnosis and treatment records after the initial treatment and recurrence. Methods We retrospectively analyzed patients diagnosed with usual-type cervical adenocarcinoma who underwent radical hysterectomy and pelvic lymph node dissection at Shengjing Hospital of China Medical University between June 2013 and June 2022. We constructed a nomogram-based postoperative recurrence prediction model, internally evaluated its efficacy, and performed internal validation. Results This study included 395 participants, including 87 individuals with recurrence. At a 7:3 ratio, the 395 patients were divided into two groups: a training set (n = 276) and a validation set (n = 119). The training set was subjected to univariate analysis, and the risk variables for recurrence included smoking, ovarian metastasis, International Federation of Gynaecology and Obstetrics (FIGO) staging, lymphovascular space invasion, perineural invasion, depth of muscular invasion, tumor size, lymph node metastasis, and postoperative HPV infection months. The aforementioned components were analyzed using logistic regression analysis, and the results showed that the postoperative HPV infection month, tumor size, perineural invasion, and FIGO stage were independent risk factors for postoperative recurrence (p<0.05). The aforementioned model was represented as a nomogram. The training and validation set consistency indices, calculated using the bootstrap method of internal validation, were 0.88 and 0.86, respectively. The model constructed in this study predicted the postoperative recurrence of usual-type cervical cancer, as indicated by the receiver operating characteristic curve. The model demonstrated good performance, as evidenced by the area under the curve, sensitivity, and specificity values of 0.90, 0.859, and 0.844, respectively. Conclusion Based on the FIGO staging, peripheral nerve invasion, tumor size, and months of postoperative HPV infection, the predictive model and nomogram for postoperative recurrence of usual-type cervical adenocarcinoma are precise and effective. More extensive stratified evaluations of the risk of cervical adenocarcinoma recurrence are still required, as is a thorough assessment of postoperative recurrence in the future.

Initial treatment for FIGO 2018 stage IIIC cervical cancer based on histological type: A 14-year multicenter study. Cancer Med 2023; 12:19617-19632. [PMID: 37768092 PMCID: PMC10587947 DOI: 10.1002/cam4.6586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/27/2023] [Accepted: 09/13/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND To compare the oncological outcomes of radical chemotherapy (R-CT), abdominal radical hysterectomy (ARH), and neoadjuvant chemotherapy and radical surgery (NACT) for International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIIC cervical cancer, according to histological types: squamous cell carcinoma (SCC) and adenocarcinoma (AC)/adenosquamous cell carcinoma (ASC). METHODS A comparison of 5-year overall survival (OS) and disease-free survival (DFS) was performed for the SCC and AC/ASC subgroups for the three initial treatments, assessed using Kaplan-Meier and Cox proportional hazards regression analysis and validated using propensity score matching (PSM). RESULTS The study included 4086 patients: R-CT, n = 1913; ARH, n = 1529; and NACT, n = 644. AC/ASC had a lower survival rate (63.7%) than SCC (73.6%) and a higher recurrence and mortality rate (36.3% and 26.4%, respectively). The 5-year OS and DFS rates were different in the SCC group for R-CT, ARH, and NACT (OS: 69.8% vs. 80.8% vs. 73.0%, p < 0.001; DFS: 66.7% vs. 70.7% vs. 56.4%, p < 0.001), also in the AC/ASC group (OS: 46.1% vs. 70.6% vs. 55.6%, p < 0.001; DFS: 42.7% vs. 64.6% vs. 40.8%, p < 0.001). As for initial treatment, survival outcomes were worse for AC/ASC treated with R-CT and ARH than for SCC (both p < 0.05), with no group differences between the two treated with NACT. CONCLUSION Initial treatment influences oncological prognosis for patients with FIGO 2018 stage IIIC cervical cancer. ARH is an alternative treatment for stage IIIC cervical SCC and AC/ASC, and NACT needs to be chosen with caution, moreover, R-CT for AC/ASC requires careful selection.

[PMID: 35410240 PMCID: PMC9003999 DOI: 10.1186/s12905-021-01588-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 12/29/2021] [Indexed: 11/18/2022] Open
Abstract
Background Cervical adenosquamous carcinoma (ASC) was previously thought to be a subtype of cervical adenocarcinoma, but recent studies have found that the clinical features of the two diseases are different. Moreover, the pathological characteristics, survival, prognosis, and optimal ASC therapy remain unknown. This study aims to retrospectively analyze the postoperative survival of patients with early-stage ASC and to evaluate their condition after treatment with postoperative concurrent chemoradiotherapy (CCRT) and prophylactic irradiation of the para-aortic lymphatic drainage area. Methods This study enrolled 131 patients with pathologically confirmed ASC screened from 3502 patients with confirmed stage I–II cervical cancer diagnosis who had completed surgical treatments in our hospital. Among the 131 enrolled patients, 75 patients received CCRT, 33 patients received chemotherapy (CT), and 23 patients did not receive adjuvant treatment (named surgery alone (S alone). Of the 75 patients CCRT, 43 patients received prophylactic irradiation of the para-aortic lymphatic drainage area. The efficacy of the postoperative treatments of patients among groups (CCRT, CT, and S alone) was compared. Results The median follow-up time, age, and overall survival (OS) were 76 months, 43 years, and 74 months, respectively. The 3- and 5-year survival rates were 82% and 71.4%, respectively. The median disease-free survival (DFS) was 64 months. Cox regression analysis showed that postoperative adjuvant treatment modalities and positive lymph node metastases were associated with OS and DFS. Patients who received CCRT treatment had higher OS and DFS than those with CT and S alone. Prophylactic irradiation of the para-aortic lymphatic drainage area did not improve the OS and DFS of patients with CCRT treatment. However, further subgroup analysis suggested that it might improve survival rates in patients who had positive pelvic lymph nodes as confirmed by postoperative pathology. Conclusion Postoperative CCRT improved the survival rates in patients with early-stage ASC. The value of prophylactic irradiation of the para-aortic lymphatic drainage area remains debatable, but it may benefit patients with pelvic lymph node involvement.

Oncologic outcomes of patients with FIGO 2014 stage IB-IIA cervical adenocarcinoma who underwent radical surgery. Arch Gynecol Obstet 2022; 306:1657-1664. [PMID: 35303151 DOI: 10.1007/s00404-022-06507-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Accepted: 03/04/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE To identify prognostic factors of early-stage cervical adenocarcinoma in patients with FIGO IB-IIA, who were treated with radical surgery. MATERIALS AND METHODS Clinical data of 64 patients with stage IB-IIA cervical adenocarcinoma who underwent radical hysterectomy and lymphadenectomy with or without adjuvant therapy between 1993 and 2019 were retrospectively reviewed. The clinicopathologic factors that affect the oncological outcomes were evaluated. The Kaplan-Meier method was used for the assessment of survival outcomes. Survival curves were compared using the log-rank test. RESULTS The 5-year recurrence-free survival and 5-year disease-specific survivals were 83% and 98%, respectively. Tumor size, stage of disease and uterine spread were significantly related prognostic factors for shorter recurrence-free survival. During the follow-up, nine (14.1%) patients recurred. Five of them were extrapelvic recurrence. No correlation was identified between histopathologic subtype and extrapelvic recurrence (p = 0.265). There was no difference between adjuvant only radiotherapy and concurrent chemoradiotherapy on recurrence-free survival in a univariate analysis adjusting for prognostic factors. CONCLUSION It is important to determine the prognostic factors that predict disease outcome in surgically treated cervical adenocarcinoma for tailored adjuvant treatment. Tumor size, stage and uterine spread are determinant factors for recurrence. Risk stratifications, including uterine spread may especially be useful for patients with AC.

Abstract
INTRODUCTION A recent prospective randomized study demonstrated that minimally invasive surgery (MIS) was inferior to open surgery in disease survival in early-stage cervical cancer. Our aim was to investigate whether there were survival benefits of preoperative conization prior to MIS for early-stage cervical cancer. METHODS We retrospectively analyzed patients who eventually underwent definitive MIS with stage IA2 to IB1 (no >2 cm) squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma. Preoperatively, the patients were separated into 2 groups: one managed with conization and the other undergoing biopsy without conization. Propensity scoring weight and matching were used to reduce the influence of possible allocation biases. The Cox regression model was used for univariate and multivariate analyses of disease recurrence and survival. RESULTS 227 patients were contained in this study (99 patients in the conization group and 128 patients in the nonconization group). The 5-year DFS of the conization group was statistically better than that of the nonconization group (98.4% vs. 91.8%, p = 0.011). By univariate analysis, conization (HR = 0.11, 95% CI = 0.01-0.87, p = 0.03) and histologic cell type (p = 0.01) were considered as risk factors for recurrence. Multivariate analysis further confirmed conization (HR = 0.04, 95% CI = 0.01-0.51, p = 0.01) and histologic cell type (p < 0.01) correlated with DFS. After propensity score matching (1:1), 84 patients were included in the conization and nonconization groups, respectively, with 5-year DFS still higher in the conization group (98.3% vs. 92.9%, p = 0.037). The results after univariate and multivariate analyses were consistent with those prior to propensity score matching. CONCLUSION Preoperative conization in conjunction with MIS seemed to be a safe and feasible approach, with results that may have implications for the reduction of recurrence. Histologic cell type also impacted survival. Therefore, more future prospective studies are warranted.

Abstract
Introduction Historically, the incidence rate of cervical cancer (CC) in Eastern Europe and particularly in Bulgaria has constantly been higher than that in the other European countries. Adenosquamous carcinoma (ASC) is a rare histological subtype of CC with incidence rate of less than 6 per 100,000. We aimed to analyze the epidemiology and prognosis of all Bulgarian patients with ASC, registered at the Bulgarian National Cancer Registry (BNCR), and to compare patients’ characteristics and outcomes with those of patients, treated at a large specialized institution – the Department of Gynecologic Oncology, University Hospital in Pleven, Bulgaria. Materials and Methods This is a retrospective study of all cases of ASC, registered at the BNCR for a 10-year period of time. The Kaplan–Meier analysis with Log rank test was used to estimate the significant differences. Results The incidence rate of ASC was calculated as 3.2% of all CC registered in BNCR and 4.97% of all stage I patients, treated in our department. The 5-year overall survival (OS) rate of all patients with ASC tumors from the registry was 50.5%. A total of 171 (48.4%) of the patients had T1 tumors and a 5-year OS of 67.1%. Lymph node status was a significant prognostic factor for OS (p=0.001). Thirty-one patients with T1 tumors and ASC histology were treated in our department for the same period of time. Lymph node metastases were found in 10 of them (32.2%). The 5-year observed OS in ASC group was 74.19%. Conclusion The histological subtype of cancer of the uterine cervix has an impact on prognosis and should not be simply considered as a descriptive characteristic but a poor prognostic feature and should be an integral part of the decision-making in clinical management of patients.

HER3 protein expression as a risk factor for post-operative recurrence in patients with early-stage adenocarcinoma and adenosquamous carcinoma of the cervix. Oncol Lett 2020; 20:38.

Abstract
Patients with cervical adenocarcinoma (AC) and adenosquamous carcinoma (ASC) have a poorer prognosis than those with squamous cell carcinoma (SCC). Erb-b2 receptor tyrosine kinase 3 (HER3) is a member of the epidermal growth factor receptor family and its expression is associated with unfavorable prognosis in several cancer types, including SCC of the cervix. As there is limited information on the prognostic value of HER3 for AC and ASC of the cervix, the present study aimed to evaluate the expression of HER3 and its impact on post-operative recurrence in patients with AC and ASC of the cervix. This retrospective study included 39 patients with early-stage AC and ASC who underwent primary surgery between January 1997 and December 2017. Immunohistochemical staining for HER3 was performed on formalin-fixed paraffin-embedded surgical specimens. The possible influence of HER3 expression on disease-free survival (DFS) was studied by using multivariate Cox regression with adjustment for established risk factors of post-operative recurrence. High expression of HER3 (HER3-high) was detected in 85.1% of cases of AC (23/27) and in 58.3% of cases of ASC (7/12). The median follow-up duration was 63.1 months and Kaplan-Meier analysis indicated that the 5-year DFS rates of patients with AC and ASC of the cervix were 56.7% in patients with HER3-high and 77.8% in patients with HER3-low (log rank, P=0.20). On multivariate analysis, HER3-high [hazard ratio (HR)=6.32, 95% CI: 1.10–36.26, P=0.039), pelvic lymph node metastasis (HR=7.61, 95% CI: 2.07–28.00, P=0.002) and vascular invasion (HR=4.28, 95% CI: 1.12–16.31, P=0.033) were indicated to be independent predictors of DFS. To date, the present study is the most comprehensive analysis to evaluate the expression of HER3 in patients with early-stage AC and ASC of the cervix. The results suggested that HER3 overexpression may be an independent risk factor for post-operative recurrence. However, these results and the prognostic value of HER3 should be confirmed in a larger sample.

Fertility-sparing surgery of cervical cancer >2 cm (International Federation of Gynecology and Obstetrics 2009 stage IB1-IIA) after neoadjuvant chemotherapy. Int J Gynecol Cancer 2019; 30:115-121. [PMID: 31744889 DOI: 10.1136/ijgc-2019-000647] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2019] [Revised: 07/25/2019] [Accepted: 07/30/2019] [Indexed: 01/27/2023] Open
Abstract
OBJECTIVE To assess the feasibility, safety, oncological, and obstetric outcomes in patients with cervical tumors >2 cm treated with neoadjuvant chemotherapy in preparation for abdominal radical trachelectomy. METHODS A retrospective analysis of patients with cervical cancer >2 cm (up to 6 cm) was conducted in patients who were selected to receive neoadjuvant chemotherapy before abdominal radical trachelectomy. Surgical and clinical outcomes were examined in relation to radiological and pathological results. In addition, obstetric outcomes were described. The Mann-Whitney U test and Fisher's exact test were performed to compare radiological findings between successful and unsuccessful abdominal radical trachelectomy procedures. International Federation of Gynecology and Obstetrics (FIGO) 2009 staging classification was used for this study. RESULTS A total of 19 women were treated with neoadjuvant chemotherapy for cervical tumors >2 cm at our institution between May 2006 and July 2018. The median age was 28 years (range 19-36). The distribution of FIGO stages was seven patients stage IB1 (37%), 10 patients stage IB2 (53%), and two patients (10%) stage IIA. Mean clinical tumor size was 4.4 cm (range 3.5-6.0). Histology revealed 74% cases of squamous cell carcinoma. The remaining patients had adenocarcinoma (21%) and only one patient had clear cell adenocarcinoma (5%). Chemotherapy consisted of six weekly cycles of cisplatin (70 mg/m2) and paclitaxel (70 mg/m2). In 15 of the 19 patients (74%) fertility was successfully preserved. In the four patients in whom fertility preservation failed, one patient had stable disease after three cycles and did not meet the criteria for fertility-sparing surgery and three patients had intra- or post-operative indications for adjuvant therapy. Three of the 19 patients (15.7%) had a relapse, two of whom died. One case was in the group of successful abdominal radical trachelectomy. CONCLUSION Neoadjuvant chemotherapy followed by fertility-sparing surgery may be a feasible and safe option in select patients with cervical tumors >2 cm. Unfavorable prognostic factors are defined as non-responsiveness and non-squamous pathology, which can help in patient selection for fertility-sparing surgery.

Abstract
The aim of this study was to determine the prognostic impact of histological type among squamous cell carcinoma (SCC), adenocarcinoma (AC) and adenosquamous carcinoma (ASC) on the treatment outcome of early-stage cervical cancer patients after radical hysterectomy. The cohort comprised of 626 patients, diagnosed with stages IA2-IB1 cervical cancer between 1987 and 2013. Four hundred and one patients had SCC, 190 had AC and 35 had ASC. The 5-year disease-free survival (DFS) rates for AC, SCC and ASC were 89.3% (95%CI 83.2-93.2), 88.7% (95%CI 84.8-91.7) and 82.1% (95%CI 61.9-92.2), respectively (p = .594). In multivariate analyses, only older age and deep stromal invasion were statistically significantly associated with DFS, whereas histologic cell type was not (p = .524). Subgroup analysis showed that in the intermediate-high-risk groups, the SCC group had a significantly longer DFS, compared with the AC group or the ASC group (p = .001) while there was no DFS difference in the low-risk group. We believe that histologic cell type had no impact in low-risk early-stage cervical cancer patients. However, in the intermediate-high-risk groups, SCC is a more favourable factor for survival than AC/ASC.

Abstract
OBJECTIVE The aim of this study was to identify prognostic factors and establish a model for predicting life expectancy in International Federation of Gynecology and Obstetrics stage IVB cervical cancer patients. METHODS The baseline characteristics and outcome data of patients with stage IVB cervical cancer between May 1994 and October 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to identify independent predictors of survival in stage IVB cervical cancer patients. RESULTS A total of 107 patients were included in our database. The median overall survival (OS) period was 16 months. Multivariate analysis revealed that the metastatic site (hazards ratio, 3.09; 95% confidence interval, 1.94-4.88; P < 0.0001) and a white blood cell (WBC) count exceeding 10,000/μL (hazards ratio, 2.02; 95% confidence interval, 1.19-3.30; P = 0.0102) were significant prognostic factors in terms of OS. Patient survival was inversely correlated with the number of these prognostic factors possessed. When the patients were divided into 3 prognostic groups, the median OS of the patients with 0, 1, or 2 poor prognostic factors was 26, 12, and 7 months, respectively. Among the patients with WBC counts of less than 10,000/μL, treatment with radiotherapy resulted in improved survival compared with chemotherapy or palliative care alone. In contrast, radiotherapy had minimal effects on survival in patients with WBC counts of greater than 10,000/μL. CONCLUSIONS The metastatic site and an elevated WBC count are significant prognostic factors in patients with stage IVB cervical cancer. Our prognostic model composed of these 2 clinical variables might enable physicians to predict survival more accurately.

Abstract
Objective To compare the survival outcomes of patients with cervical squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) among patients with locally advanced cervical cancer that were treated with definitive radiotherapy. Methods The baseline characteristics and outcome data of patients with locally advanced cervical cancer who were treated with definitive radiotherapy between November 1993 and February 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of AC/ASC histology. Results The patients with AC/ASC of the cervix exhibited significantly shorter overall survival (OS) (p=0.004) and progression-free survival (PFS) (p=0.002) than the patients with SCC of the cervix. Multivariate analysis showed that AC/ASC histology was an independent negative prognostic factor for PFS. Among the patients who displayed AC/ASC histology, larger tumor size, older age, and incomplete response to radiotherapy were found to be independent prognostic factors. PFS was inversely associated with the number of poor prognostic factors the patients exhibited (the estimated 1-year PFS rates; 100.0%, 77.8%, 42.8%, 0.0% for 0, 1, 2, 3 factors, respectively). Conclusion Locally advanced cervical cancer patients with AC/ASC histology experience significantly worse survival outcomes than those with SCC. Further clinical studies are warranted to develop a concurrent chemoradiotherapy (CCRT) protocol that is specifically tailored to locally advanced cervical AC/ASC.

Abstract
PURPOSE To evaluate the clinical outcomes in patients with International Federation of Gynecology and Obstetrics (FIGO) stage I to IVA squamous cell carcinoma (SCC), adenocarcinoma (AC), and adenosquamous carcinoma (ASC) of the uterine cervix after definitive radiotherapy. METHODS Patients with a primary diagnosis of FIGO stage I-IVA SCC, AC, and ASC of the uterine cervix who had undergone definitive beam radiation with implants or isotopes between 1988 and 2013 were identified using the Surveillance, Epidemiology, and End Results database. Univariate and multivariate Cox regression analyses were performed to analyze the effect of histologic subtype on cause-specific survival (CSS) and overall survival (OS). RESULTS A total of 8751 were identified, and 86.0, 10.6, and 3.4 % of patients were SCC, AC, and ASC, respectively. AC patients were more often well differentiated, while more patients were poorly/undifferentiated in ASC subtype. A higher percentage of AC and ASC patients were stage I, and fewer had stage III compared to SCC. Univariate and multivariate Cox analyses showed that histologic subtype was an independent prognostic factor for CSS and OS. SCC subtype had a better CSS and OS compared to AC and ASC subtype. The survival between AC and ASC had no significant difference. The impact of the histologic subtype on CSS and OS was not affected by FIGO stage and the year of diagnosis. CONCLUSION AC and ASC subtypes are independent prognostic factors for cervical cancer patients treated with definitive radiotherapy. AC and ASC subtypes are associated with poor survival outcomes than those with SCC.

Abstract
BACKGROUND/AIMS The aim of this study was to compare the survival outcomes of adenocarcinoma and adenosquamous carcinoma in early-stage cervical cancer patients after radical hysterectomy. METHODS A retrospective analysis was performed of stage IB-IIA cervical cancer patients with adenocarcinoma or adenosquamous carcinoma who underwent radical hysterectomy at Seoul National University Hospital between 1998 and 2008. RESULTS A total of 166 patients with adenosquamous carcinoma (ASC) (n = 38) and adenocarcinoma (AC) (n = 128) were identified. In terms of baseline characteristics, the ASC group had higher rates of lymph node metastasis, deep stromal invasion, and lymphovascular space invasion than the AC group. However, there was no significant difference between the two histological subtypes in terms of recurrence-free survival (p = 0.396) and overall survival (p = 0.223). Patients with ASC showed similar outcomes to those with AC when limiting to either an intermediate/high-risk group or patients who underwent adjuvant concurrent chemoradiotherapy. CONCLUSION Although the ASC group presented poorer pathologic findings after radical hysterectomy compared with the AC group, there was no significant difference in survival outcomes. This suggests that intermediate/high-risk patients with ASC may be successfully treated with postoperative concurrent chemoradiotherapy.

Abstract
BACKGROUND This study was undertaken to evaluate the surgical outcomes of patients with stage IA2 cervical cancer treated with radical hysterectomy. Data for 58 patients who underwent modified radical hysterectomy or radical hysterectomy with pelvic lymphadenectomy between January 2003 and December 2012 at Chiang Mai University Hospital were retrospectively reviewed. The analysis included clinico-pathological risk factors (nodal metastasis, parametrial involvement), adjuvant treatment, 5-year disease-free survival and 5-year overall survival. All pathologic slides were reviewed by a gynecologic pathologist. Follow-up methods included at least cervical cytology and colposcopy with directed biopsy if indicated. Univariate analysis was performed to identify factors associated with median survival. At the median follow up time of 73 months, the 5-year disease-free survival and the 5-year overall survival were 97.4% and 97.4%, respectively. Two (3.4%) patients had pelvic lymph node metastases. In a univariate analysis, there was no statistically significant association between survival and prognostic factors such as age, histological cell type, lymph-vascular space invasion, vaginal margin status and lymph node status. Surgical and survival outcomes of women with stage IA2 cervical cancer are excellent. No parametrial involvement was detected in our study. Patients with stage IA2 cervical cancer may be treated with simple or less radical hysterectomy with pelvic lymphadenectomy.

Abstract
ObjectiveThe aim of this study was to compare the survival outcomes of adenosquamous carcinoma (ASC) and adenocarcinoma (AC) of the cervix.MethodsWe searched PubMed and Embase for observational studies that compared the outcomes of 2 histologic subtypes. Hazards ratios (HRs) with 95% confidence intervals (CIs) were calculated with a fixed effects model.ResultsA total of 17 studies were included in the analyses. Patients with ASC were associated significantly with poorer overall survival (death HR, 1.27; 95% CI, 1.12–1.43; I2= 0%) and recurrence-free survival (recurrence HR, 1.43; 95% CI, 1.05–1.95; I2= 19.4%) than those with AC. For clinical stages I and II in particular, ASC predicted significantly poorer outcomes compared with AC (death HR, 1.41; 95% CI, 1.17–1.70; I2= 0%).ConclusionsThis meta-analysis suggests that ASC may have poorer outcomes compared with AC of the cervix.

Abstract
OBJECTIVE To evaluate the prognostic influence of adenocarcinoma (AC) and adenosquamous carcinoma (ASC) in patients with FIGO stage IB-IIA cervical cancer who received radical hysterectomy followed by adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). METHODS We analyzed 1323 patients who satisfied the following criteria: histologically proven squamous cell carcinoma (SCC), AC, or ASC of the uterine cervix; FIGO stage IB-IIA disease; no history of neoadjuvant chemotherapy; and a history of radical hysterectomy with pelvic lymph node (PLN) dissection, followed by postoperative pelvic RT at a dose ≥ 45 Gy. The median age was 50 years. Median RT dose delivered to the whole pelvis was 50.4 Gy, and 219 (16.6%) patients received brachytherapy at a median dose of 24 Gy. Concurrent chemotherapy was delivered to 492 (37.2%) patients. RESULTS Pathologic risk factors were not different according to pathologic subtype. The median follow-up duration was 75.7 months. Locoregional recurrence-free survival, relapse-free survival (RFS), and overall survival were significantly affected by histology, tumor size, PLN metastasis, parametrial invasion, lymphovascular invasion, and deep stromal invasion. The 5-year RFS rates were 83.7%, 66.5%, and 79.6% in patients with SCC, AC, and ASC histology, respectively (P<0.0001). By multivariate analysis, AC histology was the only significant prognostic factor affecting all survival outcomes. CONCLUSIONS AC histology was associated with poor survival outcomes in patients with FIGO stage IB-IIA cervical cancer who received adjuvant RT or CCRT. Prognosis of ASC histology was closer to that of SCC histology than that of AC histology.

Abstract
Background Insights into the mechanisms associated with chemotherapy-resistance are important for implementation of therapeutic strategies and for unraveling the mode of action of chemotherapeutics. Although cidofovir (CDV) has proven efficacious in the treatment of human papillomavirus (HPV)-induced proliferation, no studies concerning the development of resistance to CDV in HPV-positive tumor cells have been performed yet. Methods From the cervical carcinoma SiHa cells (SiHaparental), which are HPV-16 positive, cidofovir-resistant cells (SiHaCDV) were selected, and differential gene expression profiles were analyzed by means of microarrays. We examined in vitro phenotyping of resistant cells compared to parental cells as well as tumorigenicity and pathogenicity in a mouse-xenograft model. Results SiHaCDV had a resistant phenotype and a reduced growth both in vitro and in vivo. A markedly diminished inflammatory response (as measured by production of host- and tumor-derived cytokines and number of neutrophils and macrophages in spleen) was induced by SiHaCDV than by SiHaparental in the xenograft model. Gene expression profiling identified several genes with differential expression upon acquisition of CDV-resistance and pointed to a diminished induction of inflammatory response in SiHaCDV compared to SiHaparental. Conclusions Our results indicate that acquisition of resistance to cidofovir in SiHa cells is linked to reduced pathogenicity. The present study contributes to our understanding on the antiproliferative effects of CDV and on the mechanisms involved, the inflammatory response playing a central role.

Abstract
OBJECTIVE To investigate the utility of serum squamous cell carcinoma antigen (SCC-Ag) levels upon the diagnosis of recurrent cervical cancer for decision making in patient management. METHODS Clinical records from 167 cervical cancer patients who developed recurrence between April 1996 and September 2010 were reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of serum SCC-Ag levels at the time of recurrence. The effects of various salvage treatments on survival outcomes of recurrent cervical cancer were examined with respect to serum SCC-Ag levels. RESULTS Serum SCC-Ag levels were elevated (>2.0 ng/mL) in 125 patients (75%) when recurrence was diagnosed. These patients exhibited significantly shorter postrecurrence survival than those with normal SCC-Ag levels (log-rank; p=0.033). Multivariate analyses revealed that an elevated serum SCC-Ag level was an independent prognostic factor for poor postrecurrence survival. In patients with SCC-Ag levels <14.0 ng/mL, radiotherapy or surgery resulted in improved survival compared with chemotherapy or supportive care. In contrast, in patients with SCC-Ag levels of ≥14.0 ng/mL, salvage treatment with radiotherapy had only a minimal impact on postrecurrence survival. CONCLUSION The serum SCC-Ag level measured when cervical cancer recurrence is diagnosed can be useful for deciding upon the appropriate salvage treatment.
