Abstract
BACKGROUND This study aimed to evaluate the outcomes of patients diagnosed with stage IB2/IIA2 cervical squamous cell carcinoma who underwent neoadjuvant chemotherapy (NACT) prior to radical hysterectomy compared to those who did not receive NACT before surgery. MATERIALS AND METHODS This is a multicenter study including data of 6 gynecological oncology departments. The study is approved from one of the institution's local ethics committee. Patients were stratified into two cohorts based on the receipt of NACT preceding their surgical intervention. Clinico-pathological factors and progression-free survival were analyzed. RESULTS Totally 87 patients were included. Lymphovascular space invasion (LVSI) was observed as 40% in the group receiving NACT, while it was 66.1% in the group not receiving NACT (p = 0.036). Deep stromal invasion (> 50%) was 56% in the group receiving NACT and 84.8% in the group not receiving NACT (p = 0.001). In the univariate analysis, application of NACT is statistically significant among the factors that would be associated with disease-free survival. Consequently, a multivariate analysis was conducted for progression-free survival, incorporating factors such as the depth of stromal invasion, the presence of LVSI, and the administration of NACT. Of these, only the administration of NACT emerged as an independent predictor associated with decreased progression-free survival. (RR:5.88; 95% CI: 1.63-21.25; p = 0.07). CONCLUSIONS NACT shouldn't be used routinely in patients with stage IB2/IIA2 cervical cancer before radical surgery. Presented as oral presentation at National Congress of Gynaecological Oncology & National Congress of Cervical Pathologies and Colposcopy (2022/ TURKEY).

Abstract
The clinical benefit of neoadjuvant chemotherapy (NACT) before concurrent chemoradiotherapy (CCRT) vs. adjuvant chemotherapy after CCRT is debated. Non-response to platinum-based NACT is a major contributor to poor prognosis, but there is currently no reliable method for predicting the response to NACT (rNACT) in patients with locally advanced cervical cancer (LACC). In this study we developed a machine learning (ML)-assisted model to accurately predict rNACT. We retrospectively analyzed data on 636 patients diagnosed with stage IB2 to IIA2 cervical cancer at our hospital between January 1, 2010 and December 1, 2020. Five ML-assisted models were developed from candidate clinical features using 2-step estimation methods. Receiver operating characteristic curve (ROC), clinical impact curve, and decision curve analyses were performed to evaluate the robustness and clinical applicability of each model. A total of 30 candidate variables were ultimately included in the rNACT prediction model. The areas under the ROC curve of models constructed using the random forest classifier (RFC), support vector machine, eXtreme gradient boosting, artificial neural network, and decision tree ranged from 0.682 to 0.847. The RFC model had the highest predictive accuracy, which was achieved by incorporating inflammatory factors such as platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, neutrophil-to-albumin ratio, and lymphocyte-to-monocyte ratio. These results demonstrate that the ML-based prediction model developed using the RFC can be used to identify LACC patients who are likely to respond to rNACT, which can guide treatment selection and improve clinical outcomes.

Neoadjuvant Chemotherapy Prior Fertility-Sparing Surgery in Women with FIGO 2018 Stage IB2 Cervical Cancer: A Systematic Review. Cancers (Basel) 2022; 14:cancers14030797. [PMID: 35159063 PMCID: PMC8833789 DOI: 10.3390/cancers14030797] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 01/21/2022] [Accepted: 01/22/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary In order to provide our contribution to the knowledge of women affected by IB2 cervical cancer, who wish to preserve fertility, we revised and updated the available literature in the debated issue of neoadjuvant chemotherapy prior to fertility-sparing treatment. The effectiveness of preoperative chemotherapy in tumors larger than 2 cm virtually proposes a conservative opportunity to a broader group of women, while keeping low, and hopefully absent, the risk of local and distant relapse. Available studies of neoadjuvant chemotherapy to the fertility-sparing approach have shown that a suboptimal response at surgery seems to be an independent prognostic factor in poorer survival, and, therefore, the careful selection of patients and the surgical approach after neoadjuvant chemotherapy remains crucial. Finally, we proposed an algorithm to be helpful in the decision-making process of that subgroup of patients. Abstract Nowadays, the optimal management of patients with cervical cancers measuring 2–4 cm desiring to maintain fertility is still uncertain. In this systematic review, we assessed the reliability of neoadjuvant chemotherapy (NACT) prior to fertility-sparing (FS) surgery in International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB2 cervical cancer, in terms of pathologic response, oncological and obstetric outcomes. The review of the literature was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data, using MEDLINE and PubMed, were searched for from 1 January 2005 up to 1 December 2020. We identified 20 articles and 114 women with IB2 disease, possible candidates for NACT prior to FS surgery. However, uterine conservation was achieved only in 76.7% of them. Patients reached optimal pathological response to NACT in 60.9% of cases and a TIP (cisplatin, ifosfamide and paclitaxel) regime was related to the best response. Suboptimal response to NACT appeared to be an independent negative prognostic factor. Up to 9.2% of patients recurred with a median 7.4-months DFS, and 4.6% of patients died of disease. Fifty percent of women tried to conceive after treatment and NACT prior to conization appeared to be the most promising alternative to upfront radical trachelectomy in terms of obstetric outcomes. In conclusion, NACT prior to FS surgery is an option, but the literature about this issue is still weak and FS should be carefully discussed with patients.

The Outcome of Locally Advanced Cervical Cancer in Patients Treated with Neoadjuvant Chemotherapy Followed by Radical Hysterectomy and Primary Surgery. IRANIAN JOURNAL OF MEDICAL SCIENCES 2021; 46:355-363. [PMID: 34539010 PMCID: PMC8438343 DOI: 10.30476/ijms.2020.81973.0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/13/2019] [Revised: 07/26/2019] [Accepted: 09/01/2019] [Indexed: 12/04/2022]
Abstract
Background: In recent years, before radical hysterectomy, neoadjuvant chemotherapy (NACT) has been administered to patients with locally advanced cervical cancer to shrink large tumors.
It has been reported that this treatment significantly reduces the need for radiotherapy after surgery. The current study aimed to assess the outcome
(survival, recurrence, and the need for adjuvant radiotherapy) of locally advanced cervical cancer in patients treated with NACT followed by radical hysterectomy and primary surgery. Methods: In a retrospective cohort study, the records of 258 patients with cervical cancer (stage IB2, IIA, or IIB), who referred to Imam Khomeini Hospital (Tehran, Iran)
from 2007 to 2017 were evaluated. The patients were assigned into two groups; group A (n=58) included patients, who underwent radical hysterectomy and group B (n=44)
included those, who underwent a radical hysterectomy after NACT. The outcome measures were the recurrence rate, five-year survival rate, and the need for adjuvant radiotherapy. Results: The median for overall survival time in group A and B was 113.65 and 112.88 months, respectively (P=0.970). There was no recurrence among patients with stage
IB2 cervical cancer in group B, while the recurrence rate in group A was 19.5% with a median recurrence time of 59.13 months. Lymph node involvement was the
only factor that affected patients’ survival. The need for postoperative adjuvant radiotherapy in group B was lower than in group A (P=0.002). Conclusion: NACT before the hysterectomy was found to reduce the need for postoperative radiotherapy in patients with locally advanced cervical cancer according to disease stages.
As a direct result, adverse side effects and the recurrence rate were reduced, and the overall survival rate of patients with stage IIB cervical cancer was increased.

Abstract
Purpose Non-response to platinum-based neoadjuvant chemotherapy (non-rNACT) reduces the surgical outcomes of patients with locally advanced cervical cancer (LACC). The development of an accurate preoperative method to predict a patient’s response to NACT (rNACT) could help surgeons to manage therapeutic intervention in a more appropriate manner. Patients and Methods We recruited a total of 341 consecutive patients who underwent platinum-based NACT followed by radical surgery (RS) at the Hubei Cancer Hospital between January 1, 2010 and April 1, 2020. All patients had been diagnosed with stage Ib2-IIa2 cervical cancer in accordance with the 2009 International Federation of Gynecology and Obstetrics (FIGO) classification system. First, we created a training cohort of patients who underwent NACT+RS (n=239) to develop a nomogram. We then validated the performance of the nomogram in a validation cohort of patients who underwent NACT+RS (n=102). Data analysis was conducted from October 1, 2020. First, we determined overall survival (OS) and progression-free survival (PFS) after NACT+RS. Multivariate logistic regression was then used to identify independent risk factors that were associated with the response to rNACT; these were then incorporated into the nomogram. Results The analysis identified several significant differences between the rNACT and non-rNACT groups, including neutrophil–lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), lymphocyte monocyte ratio (LMR), platelet count, and FIGO stage. The performance of the rNACT nomogram score exhibited a robust C-index of 0.76 (95% confidence interval [CI]: 0.65 to 0.87) in the training cohort and high C-index of 0.71 (95% CI: 0.62 to 0.78) in the validation cohort. Clinical impact curves showed that the nomogram had good predictive ability. Conclusion We successfully established an accurate and optimized nomogram that could be used preoperatively to predict rNACT in patients with LACC. This model can be used to evaluate the risk of an individual patient experiencing rNACT and therefore facilitate the choice of treatment.

Abstract
Background Few studies investigated the effectiveness of adjuvant chemotherapy (ACT) in patients with optimal response to neoadjuvant chemotherapy (NACT), and an optimal number of treatment cycles for these patients remains unknown. Methods A total of 261 Chinese patients with FIGO stage IB2-IIB cervical cancer who obtained an optimal response to NACT were included after radical surgery, and the disease-free survival (DFS) and overall survival (OS) of these patients treated with different cycles of postoperative ACT were compared using the Log-rank test and multivariate analysis. Results We found that the prognosis of optimal responders treated with postoperative ACT was significantly better than those without further adjuvant therapy. The multivariate analysis showed that postoperative ACT was an independent prognostic factor for DFS. However, there was no significant difference in the DFS and OS between patients who had three cycles of ACT and those with six cycles. Further analysis revealed a significant association of six cycles of ACT with the risk of leukopenia, nausea/vomiting, and rash. Conclusion Our data suggest that additional three cycles of ACT after surgery may improve the clinical outcome of optimal responders in terms of DFS, OS, and drug toxicity.

Abstract
Objectives This study aimed to assess the effect of neoadjuvant chemotherapy (NACT) on the rate of lymph node metastasis (LNM) in FIGO stage IB1-IIB cervical cancer patients and compare the LNM between NACT plus surgery and surgery only. Methods We identified 34 eligible studies in PubMed, Web of Science, Cochrane Library, and EMBASE from inception to July 27, 2019. Data analyses were performed by Stata (version 13) and Revman (version 5.3). Results In these 34 included studies, the pooled incidence of LNM was estimated as 23% (95% CI, 0.20-0.26; I2 = 79.6%, P<0.001). In the subgroup analysis, we identified five factors, including study type, year of publication, continents from which patients came, histological type and the FIGO stage. When taking FIGO stage into consideration, the LNM rate was 13% in stage IB (95% CI: 0.10-0.15; I2 = 5.5%, P=0.385), 23% in stage IIA (95% CI: 0.18-0.28; I2 = 0%, P=0.622), and 27% in stage IIB (95% CI: 0.20-0.33; I2 = 0%, P=0.898), respectively. Through the comparison between NACT plus surgery and surgery only based on the six randomized controlled trials, the incidence of positive lymph nodes was lower in patients receiving NACT plus surgery than surgery only (RR=0.57, 95% CI: 0.39-0.83; I2 = 60.5%, P=0.027). The 5-year OS was higher in the NACT + surgery group than surgery-only group (RR=1.13, 95% CI: 1.03-1.23; I2 = 0.0%, P=0.842). Conclusions Among cervical cancer in stage IB1-IIB, the preoperative NACT plus radical surgery resulted in a 23% probability of LNM, which was lower than those receiving radical surgery only. In stage IIA and IIB, the effect of NACT to reduce LNM was more obvious.

Abstract
PURPOSE To prospectively investigate changes in quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and the apparent diffusion coefficient (ADC) of diffusion-weighted imaging (DWI) in patients with cervical cancer before and after neoadjuvant chemotherapy (NACT). METHODS Thirty-eight patients with cervical cancer underwent DCE-MRI and DWI 1 week before and 4 weeks after NACT. The patients were classified into 2 groups: significant reaction (sCR) group and the non-sCR group. DCE-MRI parameters and ADC values were measured and compared between the 2 groups. RESULTS Before NACT, the mean Ktrans value was higher, but the mean Ve was lower, in the sCR group compared with the non-sCR group; these differences were statistically significant (p<0.05). After NACT, the mean Ktrans value and the delta (i.e., changed) value of Ktrans were significantly lower in the sCR group compared with the non-sCR group (p<0.05). However, the mean ADC and the delta value of the mean ADC between the 2 groups were slightly higher in the sCR group compared with the non-sCR group (p<0.05). The area under the curve of pre-mean Ktrans, DKtrans, and pre-mean Ktrans combined with post-mean ADC values were 0.801, 0.955, and 0.878, respectively (p<0.05). The optimal cutoff values for distinguishing sCR from non-sCR were pretreatment Ktrans (0.7020 min-1) and DKtrans (0.0437 min-1). CONCLUSIONS Quantitative parameters (pre-mean Ktrans, DKtrans, and pre-mean Ktrans) combined with post-mean ADC could predict treatment efficacy more precisely. However, quantitative DCE-MRI combined with DWI could not significantly improve prognostic efficacy.

Abstract
BACKGROUND There are limited data regarding the optimal management of pre-menopausal women with cervical lesions measuring 2-4 cm who desire to preserve fertility. PRIMARY OBJECTIVES To evaluate the feasibility of preserving fertility. STUDY HYPOTHESIS Neo-adjuvant chemotherapy will be effective in reducing the size of the tumor and will enable fertility-sparing surgery without compromising oncologic outcome. TRIAL DESIGN Pre-menopausal women diagnosed with stage International Federation of Gynecology and Obstetrics (FIGO) IB2, 2-4 cm cervical cancer who wish to preserve fertility will receive three cycles of platinum/paclitaxel chemotherapy. Patients with complete/partial response will undergo fertility-sparing surgery. Patients will be followed for 3 years to monitor outcome. Patients with suboptimal response (residual lesion ≥2 cm) will receive definitive radical hysterectomy and/or chemoradiation. MAJOR ELIGIBILITY CRITERIA Patients must have histologically confirmed invasive cervical cancer, 2-4 cm lesion, by clinical examination and magnetic resonance imaging (MRI), negative node, and pre-menopausal (≤40 years old). Following three cycles of neo-adjuvant chemotherapy, patients must achieve a complete/partial response (residual lesion <2 cm). Exclusion criteria include high-risk histology, tumor extension to uterine corpus/isthmus (as per MRI), and suboptimal response/progression following neo-adjuvant chemotherapy. PRIMARY ENDPOINTS Assess the rate of functional uterus defined as successful fertility-sparing surgery and no adjuvant therapy. SAMPLE SIZE A total of 90 evaluable patients will be needed to complete the study. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS Expected complete accrual in 2022 with presentation of results by 2025. TRIAL REGISTRATION NUMBER Pending ethics submission.

Abstract
This study compared the efficacy of neoadjuvant chemotherapy (NACT) followed by radical surgery (RS) vs primary surgical treatment (PST) in patients diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage IB2/IIA2 cervical cancer.Data of 303 cervical cancer patients who received primary therapy for stage IB2/IIA2 cervical cancer at 7 medical centers in Beijing, China between January 1, 2009 and December 31, 2016 and followed through December 31, 2017 were collected retrospectively. The response rates, surgical characteristics, and overall survival (OS) durations of patients who received NACT followed by RS were compared to those of patients who received PST.An improved short-term complete response rate was observed among patients who received intra-arterial chemotherapy compared with patients who had intravenous chemotherapy (18.3% vs 4.1%, Pdifference = .020). Patients who received NACT were more likely to undergo laparoscopic surgery and to have a lower blood loss volume (555.4 ± 520.2 ml vs PST, 682.5 ± 509.8 ml; P = .036) and increased estimated operative time (249.9 ± 101.9 vs PST, 225.1 ± 76.5 min; P = .022). No differences in high-risk factors (HRFs), the effects of supplemental treatment, or 5-year OS were observed between patients who received NACT and PST.Our findings indicate that patients who received NACT for FIGO stage IB2/IIA2 cervical cancer were more likely to undergo laparoscopic surgery. These findings have important implications regarding treatment with curative intent for stage IB2/IIA2 cervical cancer and warrant a further analysis of treatment strategies to ensure adequate treatment and patient-centered care.

Abstract
Aim This systematic review was designed to evaluate the efficacy of neoadjuvant chemotherapy with radical surgery vs radical surgery alone for cervical cancer. Methods A computerized search was done for trials from PubMed, EMBASE, CENTRAL, and Cochrane Database of Systematic Reviews. The trials included neoadjuvant chemotherapy plus radical surgery vs radical surgery alone. We measured overall survival (OS), disease-free survival (DFS), progression-free survival (PFS), local and distant recurrence, lymph node metastasis, and parametrial infiltration per patient. Results In all, 13 studies involving 2,158 subjects were included. In regard to OS, DFS, PFS, local and distant recurrence, and parametrial infiltration, neoadjuvant chemotherapy plus radical surgery was similar to radical surgery alone. Among them, subgroup analysis of eight studies involving 1,544 patients with locally advanced cervical cancer (FIGO stage IB2–IIB) showed that neoadjuvant chemotherapy (NACT) plus radical surgery significantly improved OS, and decreased local and distant recurrence rates, lymph node metastasis rate, and the level of parametrial infiltration compared to radical surgery alone. Conclusion The present study demonstrates that preoperative NACT is now an accepted effective procedure in selected patients with locally advanced cervical cancer (FIGO stage IB2–IIB). However, the relationship between NACT and longer DFS and PFS cannot be demonstrated by this meta-analysis. Thus, the decision to use or not to use NACT before radical surgery depends on the surgeon’s experience and clinical judgment. Nevertheless, further research in this field is urgently needed to confirm it.

Abstract
BACKGROUND Local advanced cervical cancer (LACC) is a considerable health crisis for women, and neoadjuvant chemotherapy (NACT) followed by radical surgery has been a suggested therapy method. However, the correlation between the tumor treatment response to NACT and the prognosis of LACC remains controversial. METHODS A comprehensive meta-analysis was performed to precisely assess the prognostic role of the clinical response and pathological response to NACT for LACC. The included studies were identified using PubMed and Web of Science up to July 2017. Hazard ratios (HR) and corresponding 95% confidence intervals (95% CI) for overall survival (OS) and disease-free survival (DFS) were determined using Review Manager (version 5.3) and Stata (version 12). RESULTS A total of 13 publications of 4727 cases were included. The treatment clinical response rate ranged from 58.49% to 86.54%, and the pathological response rate was 7.5% to 78.81%. Our combined results suggested that a clinical response was favorable for OS (HR=3.36, 95% CI: 2.41-4.69) and DFS (HR=2.36, 95% CI: 1.82-3.06). Further, a pathological response predicts favorable OS (HR=5.45, 95% CI: 3.42-8.70) and DFS (HR=3.61, 95% CI: 2.0-6.52). CONCLUSION The response to NACT, including the clinical and pathological response, was associated with a favorable prognosis for patients with LACC. However, the predictive value of this factor in clinical practice warrants further in-depth research.

Abstract
It is still controversial whether cervical cancer patients with clinical responses after neoadjuvant chemotherapy (NACT) have a better long-term survival or not. This study was designed to investigate the effect of the clinical response on the disease-free survival (DFS) of cervical cancer patients undergoing NACT. A total of 853 patients from a retrospective study were used to evaluate whether the clinical response was an indicator for the long-term response, and 493 patients from a prospective cohort study were used for further evaluation. The survival difference was detected by log-rank test, univariate and multivariate Cox regression and a pooled analysis. The log-rank test revealed that compared with non-responders, the DFS of responders was significantly higher in the retrospective data (P = 0.007). Univariate Cox regression showed that the clinical response was an indicator of long-term survival in the retrospective study (HR 1.83, 95% CI 1.18-2.85, P = 0.007). In a multivariate Cox model, the clinical response was still retained as an independent significant prognostic factor in the retrospective study (HR 1.59, 95% CI 1.01-2.50, P = 0.046). The result was also validated in the prospective data with similar results. These findings implied that the clinical response can be regarded as an independent predictor of DFS.

The association between short-term response and long-term survival for cervical cancer patients undergoing neoadjuvant chemotherapy: a system review and meta-analysis. Sci Rep 2018; 8:1545.

Abstract
Controversy exists regarding whether a short-term response has an impact on the long-term survival of cervical cancer patients undergoing neoadjuvant chemotherapy (NACT). This study was designed to identify the predictive role of an early response by pooling the results of previous studies. The PubMed and Embase databases were searched through July 2016, and the associations between an early response and disease-free survival (DFS) were pooled by hazard ratio (HR) using random effects models. Six studies involving 490 cervical cancer patients, with 336 responders and 154 non-responders, were finally included in the meta-analysis. The HR for 1-year DFS between early responders and non-responders was 0.25 (95% CI 0.10-0.58, P = 0.001). The HRs for 2-, 3-, 4-, and 5-year DFS were 0.28 (95% CI 0.15-0.56), 0.27 (95% CI 0.16-0.45), 0.29 (95% CI 0.17-0.50) and 0.33 (95% CI 0.20-0.54), respectively. No obvious heterogeneity was found among the studies, with I2 = 0, and a sensitivity analysis showed that all pooled results were robust with logHR confidence limits < 0. An early response was associated with DFS, and responders achieved a significantly higher survival rate than non-responders. This finding should be validated in future prospective studies.

Abstract
This study was designed to identify the prognostic value of early response to neoadjuvant chemotherapy (NACT) for long-term survival of cervical cancer patients. We searched Pubmed and EMBASE for studies published through July 2016 on outcomes of cervical patients that received NACT. Eight studies involving 825 cervical cancer patients were ultimately included in our meta-analysis. We pooled the hazard ratios (HR) according to random-effects models and used funnel plots with Egger's and Begg's tests to explore potential publication bias. The HR between early response and 1-year overall survival (OS) was 3.60 (95% CI 1.93–6.72; I2 = 0). Similar results were found in the analysis of 3-year OS (HR 3.34; 95% CI 2.28–4.90; I2 = 0) and 5-year OS (HR 3.44; 95% CI 2.40–4.94; I2 = 0). Sensitivity analysis showed that all of the pooled results were robust, and all logHRs had confidence limits > 0. Our findings indicate that early response is associated with long-term survival, and responders achieved a higher survival rate than non-responders.

Abstract
The role of pathological response in long-term outcome is still unclear in cervical cancer patients treated with neoadjuvant chemotherapy (NACT) in China. This study aimed to investigate the effect of optimal pathologic response (OPR) on survival in the patients treated with NACT and radical hysterectomy. First, 853 patients with stage IB2-IIB cervical cancer were included in a retrospective analysis; a Cox proportional hazards model was used to investigate the relationship between pathological response and disease-free survival (DFS). In the retrospective database, 64 (7.5%) patients were found to have achieved an OPR (residual disease <3 mm stromal invasion); in the multivariate Cox model, the risk of death was much greater in the non-OPR group than in the OPR group (HR, 2.61; 95%CI, 1.06 to 6.45; P = 0.037). Next, the role of OPR was also evaluated in a prospective cohort of 603 patients with cervical cancer. In the prospective cohort, 56 (9.3%) patients were found to have achieved an OPR; the log-rank tests showed that the risk of recurrence was higher in the non-OPR patients than in the OPR group (P = 0.05). After combined analysis, OPR in cervical cancer was found to be an independent prognostic factor for DFS.

Abstract
This study was designed to develop a risk model for disease recurrence among cervical cancer patients who underwent neoadjuvant chemotherapy and radical surgery. Data for 853 patients were obtained from a retrospective study and used to train the model, and then data for 447 patients from a prospective cohort study were employed to validate the model. The Cox regression model was used for calculating the coefficients of the risk factors. According to risk scores, patients were classified into high-, intermediate-, and low-risk groups. There were 49 (49/144, 34%) recurrences observed in the high-risk group (with a risk score ≥ 2.65), compared with 3 (3/142, 2%) recurrences in the low-risk group (with a risk score < 0.90). Disease-free survival (DFS) was significantly different (log-rank p < 0.001) among the three risk groups; the risk model also revealed a significant increase in the accuracy of predicting 5-year DFS with the area under the ROC curve (AUC = 0.754 for risk model vs 0.679 for FIGO stage system); the risk model was also validated with data from the prospective study (log-rank p < 0.001, AUC = 0.766). Both high-risk and intermediate-risk patients can be more effectively identified by this risk model.

Abstract
Neoadjuvant chemotherapy (NAC) is widely used to treat patients with locally advanced cervical cancer. Optimal pathological response to neoadjuvant therapy has proven to be a good prognostic indicator for patient survival, but the prognostic significance of a partial response remains unclear. The aim of this study was to identify prognostic predictors for patients with partial response. We included in the study 190 patients with bulky stage Ib2 or IIa cervical squamous cell cancer, who underwent neoadjuvant chemotherapy followed by surgery. A novel pathological grading system, including optimal response (complete disappearance of tumor, grade 1), viable tumor cells occupying <(2)/3 (grade 2) or >(2)/3 (grade 3) of the tumor bed area and extra-cervical tumor deposits (grade 4), was developed and associations with disease-free survival and overall survival were studied. Survival analysis was conducted using log-rank testing and Cox regression analysis. We found statistically significant differences between 4 different pathological response groups both in terms of disease-free survival (p = 0.001) and overall survival (p = 0.003). Combining adjacent survival curves in the pathological grading system allowed us to identify response grade 2 patients with disease-free and overall survival similar to those of optimal response patients (p = 0.000, p = 0.002). Multivariate analyses showed that the pathological response grading system is the only independent predictor for progression-free survival and overall survival (p = 0.001 and p = 0.007). A response grading system based on pathological parameters may be useful to predict both progression-free and overall survival in bulky stage Ib2 and IIa cervical squamous cell cancer patients treated with NAC.

Abstract
AbstractRadical trachelectomy is now recognized as a valid treatment option for young women with early-stage cervical cancer with lesions measuring less than 2 cm. However, for women with bulky lesions measuring greater than 2cm, few data are available in the literature to guide management. There are currently 2 options available: either upfront radical trachelectomy or neoadjuvant chemotherapy followed by fertility-preserving surgery. Overall, both options offer very good oncologic outcome; however, the rate of fertility preservation and obstetrical outcome seem superior after neoadjuvant chemotherapy. Advantages and disadvantages of both options are discussed and a thorough literature review is provided. Issues to be further studied are also outlined.

Abstract
Purpose The aim of our study is to investigate the differences in therapeutic effects and clinical significance between intravenous systematic chemotherapy and intra-arterial interventional chemotherapy in stage Ib2–IIb cervical carcinomas. Methods A retrospective analysis was performed on 93 cases of intravenous and 118 cases of intra-arterial neoadjuvant chemotherapy for stage Ib2–IIb cervical carcinomas treated in Peking Union Medical College Hospital from the year 2001 to 2010. Results After neoadjuvant chemotherapy, the overall response rate was 84.9% versus (vs) 88.2% and the operability rate was 77.4% vs 81.4%, for intravenous vs intra-arterial (P>0.05). There were no significant differences in toxicities, surgical duration, perioperative blood loss, and operative complications between these two groups. Postoperative pathological examination revealed a significantly lower parametrial infiltration in the intra-arterial group (12.5% vs 38.1%, P<0.05), while the positive vaginal margin, lymph node metastasis, and intravascular tumor embolus showed no significant differences. The intravenous group and the intra-arterial group had similar recurrence rate (16.0% vs 12.3%), distant metastasis rate (9.1% vs 8.5%), and 5 year survival rate (79.5% vs 84.9%), without significant differences. Conclusion Neoadjuvant chemotherapy with cisplatin and 5-fluorouracil are safe and effective for patients with locally advanced cervical carcinomas. The intravenous and the intra-arterial approaches present with similar chemotherapy efficacy and clinical outcome. Since it is more simple and economical, the intravenous systematic approach shows greater value in clinical application.

Analysis of prognostic factors for patients with bulky squamous cell carcinoma of the uterine cervix who underwent neoadjuvant chemotherapy followed by radical hysterectomy. Int J Clin Oncol 2014; 20:345-50. [PMID: 24825458 DOI: 10.1007/s10147-014-0702-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2013] [Accepted: 04/21/2014] [Indexed: 10/25/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) is not yet widely recommended for the treatment of stage I/II cervical cancer. However, it may be possible to achieve a favorable outcome by selecting appropriate patients. In the present study, prognostic factors were retrospectively investigated to obtain data for devising individualized NAC. PATIENTS AND METHODS The subjects were 33 patients with bulky stage Ib2-IIb squamous cell carcinoma (SCC) of the uterine cervix who gave consent and were scheduled to undergo radical hysterectomy. The patients intravenously received irinotecan 70 mg/m(2) on days 1 and 8 and cisplatin 70 mg/m(2) on day 1 of a 21-day course, and two courses were performed in principle. The potential prognostic factors investigated were age, performance status (PS), clinical stage, lymph node metastasis and tumor size before NAC, SCC antigen value, anti-tumor response, histological effect of NAC, lymph node metastasis in resected specimens, and postoperative adjuvant therapy after NAC. The impacts of these factors on overall survival (OS) were calculated with the Cox regression model. RESULTS According to the univariate analysis, lymph node metastasis before NAC, SCC antigen value after NAC, anti-tumor response, and histological effect of NAC significantly influenced OS. These factors were tested in a multivariate model, and significant prognostic factors were lymph node metastasis before NAC (hazard ratio 0.116, P = 0.027) and anti-tumor response (hazard ratio 0.025, P = 0.003). CONCLUSION The presence or absence of lymph node metastasis by computed tomography imaging was the only significant prognostic factor identified during the pre-NAC period.

Abstract
Cervical cancer is currently the first or second leading cause of cancer-related mortality among women in developing countries. This study was conducted in order to determine whether neoadjuvant cisplatin and 5-flourouracil (NAPF) prior to surgery is superior to primary surgical treatment (PST) as a treatment option for patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IB2/IIA2 cervical cancer. A retrospective review of 195 patients with early-stage bulky cervical cancer was performed. The patients were divided into two groups, according to whether they received NAPF prior to surgery. The surgical profiles and complications, risk factors of recurrence and survival were compared between the groups. The response rate to NAPF was found to be 61.2%. There were no differences in operative time and intra-operative complications between the two groups, whereas the estimated blood loss in the NAPF and PST groups were 620.1±394.9 and 434.8±233.7 ml, respectively (P=0.000). When compared with PST, NAPF remarkably reduced tumor size (22.5 vs. 93.3%, P=0.000). Furthemore, the ratio of deep stromal invasion was significantly lower in responders to NAPF compared with that in non-responders (46.7 vs. 76.3%, respectively; P=0.004) and in the PST group (46.7 vs. 70.0%, respectively; P=0.004). No reduction of high-risk factors (HRFs) was observed. The NAPF group, even the responder subgroup, exhibited no significant improvement in progression-free survival (PFS) and overall survival (OS) compared to the PST group. In conclusion, despite the reduction of intermediate-risk factors (IRFs), neoadjuvant chemotherapy (NAC) with the NAPF regimen prior to radical surgery (RS) did not improve the prognosis in patients with FIGO stage IB2/IIA2 cervical cancer.

Responsiveness of neoadjuvant chemotherapy before surgery predicts favorable prognosis for cervical cancer patients: a meta-analysis. J Cancer Res Clin Oncol 2013; 139:1887-98. [PMID: 24022086 DOI: 10.1007/s00432-013-1509-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2013] [Accepted: 08/30/2013] [Indexed: 12/14/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) before surgery has already shown the therapy effectiveness inpatients with cervical cancer. The present meta-analysis was conducted to determine whether the response to NAC predicts for prognosis. METHODS Systematic computerized searches of the Pub-Med and Web of Knowledge were performed. Prognosis outcomes included progression-free survival (PFS), and overall survival (OS). The pooled odd ratio (OR) was estimated by using fixed-effect model or random-effect model according to heterogeneity between studies. RESULTS Eighteen studies with 1,785 patients were included. Cisplatin-based NAC treatments were most commonly used. The clinical response rate ranged from 48.4 to 93.0 %, and the pathological response rate ranged from 27.6 to 30.6 %. The pooled ORs estimating the association of PFS with NAC response were 5.707 (95 % CI3.564–9.137), 6.798 (95 % CI 4.716–9.799), 6.327 (95 %CI 4.398–9.102), and 5.214 (95 % CI 3.748–7.253) at 1-,2-, 3-, and 5-year follow-up, respectively, and the pooled ORs estimating the association of OS with NAC response were 6.179 (95 % CI 3.390–11.264), 9.155 (95 % CI5.759–14.555), 8.431 (95 % CI 5.667–12.543), and 5.785(95 % CI 4.124–8.115) at 1-, 2-, 3-, and 5-year follow-up,respectively. No obvious statistical heterogeneity was detected. Funnel plots and Egger’s tests did not reveal publication bias. Sensitivity analysis showed the results of meta-analysis were robust. CONCLUSION This meta-analysis confirms that response to NAC is an indicator for PFS and OS, and suggests that patients-achieving response of NAC before surgery predicts favorable prognosis for cervical cancer patients.
