Yeshe P, Li F. Clinical efficacy and safety of neoadjuvant chemotherapy with paclitaxel and cisplatin in combination with concurrent chemoradiotherapy for locally advanced cervical cancer: a systematic review and meta-analysis. JOURNAL OF RADIATION RESEARCH 2024:rrae073. [PMID: 39373027 DOI: 10.1093/jrr/rrae073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 07/29/2024] [Indexed: 10/08/2024]
Abstract
The meta-analysis was to evaluate the therapeutic benefits of neoadjuvant chemotherapy (NACT), primarily consisting of platinum-based regimens in conjunction with paclitaxel, when integrated with concurrent chemoradiotherapy (CCRT) for individuals afflicted with locally advanced cervical cancer (LACC). The outcomes were determined by overall survival (OS), progression-free survival (PFS), complete response rate (CRR), objective response rate, recurrence rate and adverse events. The assessment of these outcomes was based on the relative risk (RR) accompanied by its 95% confidence interval (CI). Eight articles were included for analysis. LACC patients who underwent treatment with paclitaxel combined with cisplatin (TP)-based NACT in conjunction with CCRT demonstrated improved OS at 2 (RR: 1.11, 95% CI: 1.07, 1.16, P < 0.001), 3 (RR: 1.30, 95% CI: 1.23, 1.37, P < 0.001) and 5 years (RR: 1.20, 95% CI: 1.10, 1.32, P < 0.001), as well as PFS at 1 (RR: 1.03, 95% CI: 1.00, 1.06, P = 0.035), 2 (RR: 1.21, 95% CI: 1.04, 1.40, P = 0.012), 3 (RR: 1.26, 95% CI: 1.17, 1.34, P < 0.001) and 5 (RR: 1.39, 95% CI: 1.25, 1.55, P < 0.001) years, when compared with patients who received CCRT alone. Moreover, the TP-based NACT in conjunction with CCRT achieved a higher CRR and exhibited a lower rate of disease recurrence (RR:1.28, 95% CI:1.08, 1.50, P = 0.003). No significant differences in the risk of adverse effects including anemia, leukopenia, thrombocytopenia, radiocystitis and radiation enteritis between the group treated with TP-based NACT combined with CCRT and the group treated with CCRT alone were observed. The combination of TP-based NACT and CCRT demonstrates superior clinical efficacy than CCRT alone. This study may contribute to reducing the burden of LACC by using TP-based NACT plus CCRT.

Abstract
BACKGROUND Neither improvements in surgical techniques and methods nor advances in radiotherapy equipment and techniques have significantly improved cervical cancer survival rates for quite some time. AIM By comparing the effectiveness of neoadjuvant chemotherapy in the treatment of locally advanced cervical cancer, this study aimed to explore effective treatment methods for locally advanced cervical cancer, and provide a theoretical basis to guide clinical practice. METHODS A search of PubMed, Embase, Scopus, Web of Science and Cochrane databases was undertaken to identify randomized controlled trials on the efficacy of neoadjuvant chemotherapy for locally advanced cervical cancer, where the intervention in the experimental group was neoadjuvant chemotherapy. Based on the inclusion and exclusion criteria, the studies were evaluated for quality according to the Cochrane Quality Rating Scale. Baseline information, intervention information and outcome indicators of the included studies were extracted. Meta-analysis was performed using RevMan 5.4. RESULTS Significant differences in overall survival [relative risk (RR) 1.63, 95 % confidence interval (CI) 0.69-2.57; p = 0.0007] and complete remission rate (RR 0.37, 95 % CI -0.49 to 1.23; p = 0.041) were found between the two groups. Heterogeneity of the objective response rate showed p < 0.0001 and I2 = 99 % (I2 = 99 > 50 % and p > 0.1 for the Q-test suggested strong heterogeneity). The fixed effects model was chosen for the integration statistic [standardized mean difference (SMD) 0.81, 95 % CI -0.21 to 1.83; p = 0.12]; the difference was not significant (p > 0.05). Heterogeneity of the adverse effects of neoadjuvant chemotherapy showed p < 0.0001 and I2 = 98 % (I2 = 98 %>50 % and p > 0.1 for the Q-test suggested strong heterogeneity). The fixed effects model was chosen for the integration statistic (SMD -0.023, 95 % CI -0.95 to 0.49; p = 0.53); the difference was not significant (p > 0.05). CONCLUSIONS The use of neoadjuvant chemotherapy for the treatment of locally advanced cervical cancer improved the objective response rate and the complete remission rate of patients, but failed to improve overall survival and adverse effects.

Abstract
OBJECTIVES A deep learning (DL) model using image data from pretreatment [ 18 F]fluorodeoxyglucose ([ 18 F] FDG)-PET or computed tomography (CT) augmented with a novel imaging augmentation approach was developed for the early prediction of distant metastases in patients with locally advanced uterine cervical cancer. METHODS This study used baseline [18F]FDG-PET/CT images of newly diagnosed uterine cervical cancer patients. Data from 186 to 25 patients were analyzed for training and validation cohort, respectively. All patients received chemoradiotherapy (CRT) and follow-up. PET and CT images were augmented by using three-dimensional techniques. The proposed model employed DL to predict distant metastases. Receiver operating characteristic (ROC) curve analysis was performed to measure the model's predictive performance. RESULTS The area under the ROC curves of the training and validation cohorts were 0.818 and 0.830 for predicting distant metastasis, respectively. In the training cohort, the sensitivity, specificity, and accuracy were 80.0%, 78.0%, and 78.5%, whereas, the sensitivity, specificity, and accuracy for distant failure were 73.3%, 75.5%, and 75.2% in the validation cohort, respectively. CONCLUSION Through the use of baseline [ 18 F]FDG-PET/CT images, the proposed DL model can predict the development of distant metastases for patients with locally advanced uterine cervical cancer treatment by CRT. External validation must be conducted to determine the model's predictive performance.

Abstract
OBJECTIVE The aim of this study was to evaluate the therapeutic value and treatment-related complications of adjuvant chemotherapy after concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC). DESIGN The medical records of LACC patients who underwent CCRT were reviewed retrospectively. METHODS A total of 1,138 patients with LACC who had been treated at our hospital between January 2013 and December 2017 were included in the study and classified into two groups: the CCRT group, comprising 726 patients who had received only CCRT, and the CCRT + adjuvant chemotherapy (ACT) group, comprising 412 patients who had received three cycles of adjuvant chemotherapy after CCRT. 39 patients in the CCRT group and 50 patients in the CCRT + ACT group had undergone lymphadenectomy, which revealed pathology-positive lymph nodes in 22 patients and 35 patients, respectively. Progression-free survival (PFS), overall survival (OS), and adverse events were compared. RESULTS The median follow-up time was 61 months (range: 2-96 months). No significant differences in PFS and OS were found between the two groups (p > 0.05), but more grade 3-4 acute hematologic toxicities were observed in the CCRT + ACT group than in the CCRT group (24.8% vs. 31.8%, p = 0.01). A subgroup analysis of patients with pathology-positive lymph nodes showed that the 5-year PFS and OS rates were 76.5% and 74.9%, respectively, for the CCRT + ACT group and 45.0% and 49.2%, respectively, for the CCRT group; the differences were statistically significant (p = 0.015 and 0.042, respectively). LIMITATIONS First, the sample size of the subgroup of patients with pathology-positive lymph nodes was too small for a confirmative conclusion. The heterogeneous population and the selection bias resulting from the retrospective design were the other flaws of our study. CONCLUSION The application of adjuvant chemotherapy after CCRT may be worth investigating further for women with LACC and pathology-positive lymph nodes, but this approach is associated with an increase in acute hematology toxicities.

Abstract
ObjectiveThis retrospective study aimed to evaluate the survival outcomes in International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIICp cervical cancer patients receiving different adjuvant treatment modalities after radical hysterectomy.MethodsFrom January 2008 to December 2012, patients diagnosed with cervical cancer who underwent radical hysterectomy plus retroperitoneal lymphadenectomy with pathologically confirmed positive lymph nodes, and received either radiotherapy, concurrent chemoradiation, or sequential chemoradiation, were included in this study. Survival analysis was performed according to different adjuvant treatment modalities and after adjustment using propensity score matching.ResultsA total of 192 stage IIICp cervical cancer patients were eligible. In multivariate analysis, only sequential chemoradiation versus radiotherapy was associated with both overall survival (HR 0.44, 95% CI 0.21 to 0.94, p=0.035) and disease-free survival (HR 0.26, 95% CI 0.11 to 0.57, p<0.001). The 5-year overall survival for radiotherapy, concurrent chemoradiation, and sequential chemoradiation was 71.6%, 81.7%, and 81.5%, respectively. No significant difference in overall survival was noted between the three groups (radiotherapy vs concurrent chemoradiation, p=0.15; radiotherapy vs sequential chemoradiation, p=0.09; concurrent chemoradiation vs sequential chemoradiation, p=0.95). However, sequential chemoradiation significantly increased disease-free survival compared with radiotherapy alone (79.2% vs 63.1%, p=0.028). After propensity score matching in the baseline characteristics, both overall survival (88.0% vs 71.6%, p=0.028) and disease-free survival (88.0% vs 63.1%, p=0.021) were improved in the sequential chemoradiation group compared with radiotherapy alone; no significant differences were noted between sequential chemoradiation and concurrent chemoradiation (overall survival 88.0% vs 83.8%, p=0.50; disease-free survival 88.0% vs 75.8%, p=0.28).ConclusionIn this cohort of FIGO 2018 IIICp cervical cancer patients, post-operative sequential chemoradiation was associated with higher survival compared with radiotherapy alone after propensity matching. Future prospective studies are required to further elucidate the optimal modality in node-positive cervical cancer.

Abstract
BACKGROUND Locally advanced cervical cancer (LACC) is generally treated using concurrent chemo-radiotherapy (CCRT); yet, the effectiveness of adjuvant chemotherapy (ACT) following CCRT remains controversial. METHODS The databases Embase, Web of Science, and PubMed were analyzed for relevant research. Primary endpoints included overall survival (OS) and progression-free survival (PFS). RESULTS Fifteen trials with 4041 patients were included. Pooled HRs for PFS and OS were 0.81 (95 % CI: 0.67-0.96) and 0.69 (95 % CI: 0.51-0.93), respectively. However, subgroup analyses indicated that in randomized trials and trials with larger sample sizes (n > 100) as well as ACT cycles ≤ 3, ACT was not linked with improved PFS and OS. Moreover, ACT induced a greater rate of hematologic toxicities (P < 0.05). CONCLUSION Higher quality of evidence suggests that ACT could not yield additional survival benefits for LACC; however, identifying high-risk patients who may benefit from ACT is required to design further clinical trials and better inform treatment decisions.

Abstract
BACKGROUND To investigate the long-term treatment outcomes of early stage bulky cervical cancer treated with definite chemoradiotherapy (CCRT) using intensity-modulated radiotherapy (IMRT) followed by intracavity brachytherapy (ICRT) and the impact of histologic subtype on survival. METHODS From 2004 to 2016, 126 patients with FIGO stage IB2-IIB bulky (≥4 cm) cervical cancer treated with CCRT followed by ICRT were retrospectively reviewed. Long-term treatment-related acute/late toxicities and treatment outcomes including overall survival (OS), locoregional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) were reported. Different histologic subtype between squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC)) of uterine cervix were also compared. RESULTS Median follow-up time for alive patients was 117 months. The 5-year OS, LRRFS and DMFS were 75.3%, 87.8% and 75.6%, respectively. The most common ≥ grade 3 acute toxicity was hematologic toxicity (41.3%). The rates of ≥ grade 3 late toxicities were 4% of proctitis, 0.8% of urethral stricture and 0.8% of radiation dermatitis (peri-anal skin necrosis and gangrene). The 5-year OS/LRRFS/DMFS for SCC and AC/ASC were 81.7%/93.7%/81.5% and 51.9%/65.8%/53.5%, respectively (all log-rank p < 0.05). The AC/ASC histology was an independent prognostic factor for worse OS, LRRFS, and DMFS (All p < 0.05). CONCLUSION After long-term follow up, definite CCRT using IMRT followed by ICRT is a feasible treatment with favorable acute and late treatment toxicities for patients with early stage bulky cervical cancer. This treatment outcomes were excellent for "bulky" FIGO stage IB2-IIB SCC of the uterine cervix but seemed insufficient for AC/ASC of uterine cervix.

Abstract
PURPOSE We conducted an integrated population-based analysis of histologic subtype-specific cervical cancer incidence, survival, and incidence-based mortality by race and ethnicity, with correction for hysterectomy prevalence. METHODS Using the SEER 21 and 18 registries, we selected primary cases of malignant cervical cancer diagnosed among women ≥ 15 years. We evaluated age-adjusted incidence rates among cases diagnosed between 2000 and 2018 (SEER21) and incidence-based mortality rates among deaths from 2005 to 2018 (SEER18), per 100,000 person-years. Rates were stratified by histologic subtype and race/ethnicity (incidence and mortality), and stage, age at diagnosis, and county-level measures of social determinants of health (incidence only). Incidence and mortality rates were corrected for hysterectomy using data from the Behavioral Risk Factor Surveillance System. We estimated 5-year relative survival by histologic subtype and stratified by stage at diagnosis. RESULTS Incidence rates of cervical squamous cell carcinoma were highest in Black and Hispanic women, while incidence rates of cervical adenocarcinoma (ADC) were highest among Hispanic and White women, particularly for localized ADC. County-level income and education variables were inversely associated with squamous cell carcinoma incidence rates in all racial and ethnic groups but had less influence on ADC incidence rates. Black women had the highest overall mortality rates and lowest 5-year relative survival, irrespective of subtype and stage. Disparities in survival were particularly pronounced for Black women with regional and distant ADC, compared with other racial/ethnic groups. CONCLUSION Although Black women are less likely to be diagnosed with ADC compared with all other racial/ethnic groups, they experience the highest mortality rates for this subtype, likely attributed to the poor survival observed for Black women with regional and distant ADC.

Abstract
BACKGROUND Factors that impact recurrence in stages IB to IV include larger tumor, high-risk histology, older age, and lymphovascular invasion (LVI); however, local studies on risk factors for recurrence in British Columbia and our local recurrence patterns have not been well studied. Furthermore, the efficacy of treatment modalities including surgery and chemoradiation in the different stages of cervical cancer have not been clarified in this population. OBJECTIVES The purpose of this study is to determine the disease and treatment characteristics of stages IB to IV cervical cancer which are associated with survival differences within British Columbia. METHODS/DESIGN We performed a retrospective population study. A chart review on cervical cancer patients in British Columbia between 1 January 2010 and 31 December 2017 was done. Demographic data and treatment details were collected. Data were analyzed using multivariate Cox regressions, pairwise comparison using the Log-Rank test, and chi-square tests. RESULTS We included 780 patients (stage I: 31.5%, II: 20.0%, III: 34.5%, and IV: 3.3%). LVI and p16 negativity were associated with decreased overall survival (OS), and multivariate analyses show them to be independent risk factors for poorer survival. Surgical resection in stage I was associated with improved survival, but not with stages II-IV. The use of radical radiation therapy (RT), brachytherapy, and concurrent chemotherapy were independently associated with improved survival in stages II-IV. Peri-RT chemotherapy was not associated with survival benefit in adeno/adenosquamous carcinoma. There were 180 recurrences (23.1%), mostly distant metastases (42.8%). There were fewer recurrences after resection of tumors <2 cm compared to tumors 2 cm or larger (6.49% vs 31.3%, p = 0.00011). Only 37.7% of recurrence/metastases were treated with first-line carboplatin/paclitaxel/bevacizumab, but it was associated with better OS compared to other regimens (median OS 40.1 vs 24.8 months, p = 0.03). CONCLUSION A significant portion of patients with localized cervical cancer relapse despite radical therapy, with LVI and p16 negativity associated with poorer survival. Surgical resection may still play a role in stage IB disease, while RT, brachytherapy, and concurrent chemotherapy should be considered first-line therapy in stage II-IV diseases. First-line carboplatin, paclitaxel, and bevacizumab for recurrence shows improved survival.

Objective This study aimed to assess the efficacy and safety of adjuvant chemotherapy (ACT) after concurrent chemoradiation (CCRT) in patients with locally advanced cervical cancer (LACC) via meta-analysis. Methods A systematic literature search of MEDLINE, PubMed, Web of Science, EMBASE, and the Cochrane Central Register of Controlled Trials was conducted from January 10, 1966 to May 20, 2022. Randomized controlled trials and observational studies comparing the CCRT alone with CCRT plus ACT were included. The literature search, quality assessment, and data extraction were conducted by two reviewers independently. The primary endpoints were 3-year rates of overall survival (OS) and progression-free survival (PFS). Complete response rate, local recurrence, distant metastasis, and adverse events were secondary outcomes. The hazard ratios (HRs) and relative risk (RR) were pooled. Results Nine studies with a total of 2732 patients were included in this meta-analysis, including 1411 patients in the CCRT group and 1321 in the CCRT plus ACT group. The HR for 3-year rates of OS and PFS of the CCRT group compared with the CCRT plus ACT group was 0.72 [95%confidence interval (CI) = 0.44-1.17] and 0.78 (95%CI = 0.5-1.75), respectively. No significant differences were observed between the two groups in the complete response rate (RR = 1.06, 95%CI = 0.96-1.16). However, local recurrence and distant metastasis were significantly lower in the CCRT plus ACT group than in the CCRT group (RR = 0.63, 95%CI = 0.44 -0.91 and RR = 0.64, 95%CI = 0.47-0.88). Grade 3-4 acute toxicities were more frequent in the CCRT plus ACT group (RR = 1.73, 95%CI =1.19-2.52). Conclusion Although associated with a decreased risk of local recurrence and distant metastasis, ACT did not significantly improve the survival rate and the complete response rate with increasing grade 3-4 acute toxicities in patients with LACC. Thus, this ACT regimen cannot be recommended for patients with LACC. Systematic review registration https://inplasy.com/inplasy-2022-9-0089/, identifier INPLASY202290089.

Kumar L, Upadhyay A, Jayaraj AS. Chemotherapy and immune check point inhibitors in the management of cervical cancer. Curr Probl Cancer 2022; 46:100900. [PMID: 36265252 DOI: 10.1016/j.currproblcancer.2022.100900] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 09/06/2022] [Accepted: 09/15/2022] [Indexed: 01/30/2023]
Abstract
Management of locally advanced cervix cancer underwent major change 2 decades back when concurrent chemotherapy (CCRT) (with cisplatin alone or in combination) along with definite radiation therapy (external + brachytherapy) was found to be superior compared to radiation alone in a series of randomized trials. Since then CCRT has been the standard treatment approach; this has resulted in 5-year overall survival rate of 66% and disease-free survival (DFS) of 58%. About 30% to 40% of patients with locally advanced cervical cancer continue to have treatment failure. Also, some patients experience early and late side effects of treatment with negative impact on quality of life. To improve the outcome further - recent approaches have explored use of weekly paclitaxel and carboplatin for 4 to 6 weeks as dose dense chemotherapy prior to CCRT, adjuvant chemotherapy after CCRT in high risk patients. For patients with early stage disease (IA2-IIA), short course chemotherapy prior to surgery is associated with improved outcome in many studies. Bevacizumab- an inhibitor of vascular endothelial growth factor - is associated with improved survival. More recently, addition of treatment with immune check inhibitors (to boost the ability of T cells to destroy cancer cells) have improved responses and survival in the treatment of recurrent and metastatic cervical cancer. Whether these and other similar novel agents targeting molecular pathways could be brought in front line treatment along with cytotoxic chemotherapy along with bevacizumab are potential areas of current research.

Is There a Place for Adjuvant Chemotherapy in the Treatment of Locally Advanced Cervical Cancer? Curr Oncol 2022; 29:5223-5237. [PMID: 35892984 PMCID: PMC9332289 DOI: 10.3390/curroncol29080415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 07/19/2022] [Accepted: 07/21/2022] [Indexed: 11/17/2022] Open
Abstract
Findings on the efficacy of adjuvant chemotherapy (ACT) of locally advanced cervical cancer (LACC) after the concurrent chemoradiation (CCRT) therapy were inconsistent, and the OUTBACK trial was expected to shed some light regarding the topic. Its results on ACT in LACC were negative, with the conclusion of not to use it. The objective of this review was to present the inconsistencies of previous studies, along with the OUTBACK trial in more detail, and to rethink whether its results provide an unambiguous and definite answer to the optimal position of ACT in the treatment of LACC. To critically appraise the OUTBACK trial and understand the consequences of its results, we used only randomized controlled studies (RCTs) on ACT in LACC that have been included in high-quality systematic reviews and meta-analyses. We calculated the pooled prediction intervals using a random effects meta-analysis of all published randomized studies including the OUTBACK trial. After combining the OUTBACK trial with the results of four previous randomized trials, the pooled hazard ratio for overall survival benefit of CCRT + ACT was 0.95 (95% CI 0.75; 1.20). The pooled hazard ratio of the four previous trials was 1.00 (95% CI 0.69; 1.44). The OUTBACK trial improved the precision of the pooled estimate, but the clinical heterogeneity and the consequent prediction intervals are still very wide, and with 95% reliability, we can expect that if the new study, using a similar approach to the ACT, on a randomly selected patient population from the presented five trials is conducted, its hazard ratio for overall survival after ACT would be between 0.47 and 1.93. In conclusion, there is an absolute need for further research in order to optimally define the position of ACT in the treatment of LACC.

Abstract
Objective To compare the prognostic significance of adenocarcinoma (AC) with squamous cell carcinoma (SCC) on overall survival (OS) in patients with stage IIB-IVA cervical cancer (CC) treated by external beam radiotherapy (EBRT) and brachytherapy (BRT) with/without chemotherapy registered in the Surveillance, Epidemiology, and End Results database. Methods Data of eligible patients were extracted between 2004 and 2016. A univariate analysis was conducted using the cumulative incidence function (CIF) by considering competing events and compared using Gray’s test. The significant variables in univariate analysis were further evaluated in a multivariate analysis performed with the Fine-Gray regression model. Propensity score matching (PSM) analysis was also employed to reconfirm the results found in the present study. Results A total of 2,243 patients with SCC and 176 patients with AC were extracted from the database. The 5-year OS rates were 57.8% in the SCC group and 52.8% in the AC group. 149 patients died of causes other than CC—considered as competing events. Compared with the SCC group, patients diagnosed with AC had statistically significant worse 5-year OS rate before and after PSM. In the multivariate Fine-Gray regression model, the histological subtype of AC was proven as an independent prognostic factor associated with poorer OS before [hazard ratio (HR) = 1.340; 95% confidence interval (CI): 1.081-1.660; P = 0.007] and after [HR = 1.376; 95% CI: 1.107-1.711; P = 0.004] PSM. Conclusions The histological subtype of AC is significantly correlated with impaired OS as an independent prognostic variable in patients with stage IIB-IVA CC who received EBRT and BRT compared to patients with SCC. Future studies should incorporate effective and individualized treatment strategies into clinical decision-making to improve the unsatisfactory survival outcomes for patients with AC.

Verification of HPV16 as a good prognostic factor for cervical adeno-adenosquamous carcinoma via an international collaborative study. Taiwan J Obstet Gynecol 2022; 61:494-500. [PMID: 35595444 DOI: 10.1016/j.tjog.2022.03.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/14/2021] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE This study (Asian Gynecologic Oncology Group [AGOG]13-001/Taiwanese Gynecologic Oncology Group [TGOG]1006) was to validate human papillomavirus (HPV)16 as an independent good prognostic factor and investigate the impact of treatment modalities to cervical adenocarcinoma and adenosquamous carcinoma (AD/ASC). MATERIALS AND METHODS Patients receiving primary treatment at AGOG and TGOG member hospitals for cervical AD/ASC were retrospectively (1993-2014) and prospectively (since 2014) enrolled. DNA extraction from paraffin-embedded tissue (FFPE) specimens was used for HPV genotyping. Those with suspected endometrial origin were excluded for analysis. RESULTS A total of 354 patients with valid HPV results were enrolled, 287 (81.1%) of which had HPV-positive tumors. The top-3 types were HPV 18 (50.8%), HPV16 (22.9%) and HPV45 (4.0%). The HPV16-negativity rates varied widely across hospitals. 322 patients were eligible for prognostic analyses. By multivariate analysis, advanced stage (HR5.8, 95% confidence interval [CI] 2.1-15.8; HR5.8, 95% CI 1.6-20.5), lymph node metastasis (HR4.6, 95% CI 2.7-7.9; HR7.3, 95% CI 3.8-14.0), and HPV16-positivity (HR0.3, 95% CI 0.1-0.6; HR0.3, 95% CI 0.1-0.9) were independent prognostic factors for progression-free survival (PFS) and overall survival (OS). Stage I patients with primary surgery had better 5-year PFS (82.8% vs 50.0% p = 0.020) and OS (89.3% vs 57.1%, p = 0.017) than those with non-primary surgery, while the propensity scores distribution were similar among the treatment groups. CONCLUSION This study confirmed that HPV16-positivity was a good prognostic factor for PFS and OS in AD/ASC, and patients seemed to have better outcome with primary surgery than non-primary surgery.

Abstract
Objective To compare the survival outcomes and adverse events of patients with locally advanced cervical cancer (LACC) who received platinum monotherapy with concurrent chemoradiation therapy (CCRT) versus platinum-based dual drug therapy with CCRT. Method All relevant literature was screened form the PubMed, EMBASE, Web of Science, The Cochrane Library and other databases from their establishment to October 2020. The main endpoint indicators included overall survival (OS) and progression-free survival (PFS). Grade 3 and above adverse events induced by chemotherapy were also compared. Results This study involved 17 literature and 4,106 patients. There were 2,066 patients treated with CCRT with platinum-based dual drug therapy and 2,040 patients received CCRT with platinum monotherapy. Meta-analysis results showed that, compared to CCRT with platinum monotherapy, OS (HR = 0.68, 95% CI 0.58–0.79) and PFS (HR = 0.67, 95% CI 0.58–0.77) of LACC patients were significantly improved by CCRT with platinum-based dual drug therapy. In addition, CCRT with platinum-based dual drug therapy led to more adverse reactions such as neutropenia (OR = 4.92, 95% CI 3.55–6.84), anemia (OR = 1.99, 95% CI 1.17–3.39), diarrhea (OR = 1.70, 95% CI 1.30–2.22), leukopenia (OR = 2.42, 95%CI 1.84–3.17), thrombocytopenia (OR = 2.87, 95%CI 1.44–5.72), etc. Conclusion CCRT with platinum-based dual drug therapy improved OS and PFS of LACC patients relative to the CCRT with platinum monotherapy. But it also increased the adverse reactions caused by multiple chemotherapy drugs. Thus, it is crucial to select a proper chemotherapy regimen based on the actual tolerance of patients in clinical practice.

Abstract
BACKGROUND This study aimed to compare the survival outcomes between squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix after radical radiotherapy and chemotherapy. METHODS Propensity score matching (1:4) was used to compare overall survival (OS) and disease-free survival (DFS) in cervical cancer patients with SCC and AC/ASC in China. RESULTS Five thousand four hundred sixty-six patients were enrolled according to the criteria. The 5-year OS and DFS in the SCC group (n = 5251) were higher than those in the AC/ASC group (n = 215). After PSM (1:4), the 5-year OS and DFS in the SCC group were higher than those in the AC/ASC group (72.2% vs 56.9%, p < 0.001, HR = 1.895; 67.6% vs 47.8%, p < 0.001, HR = 2.056). In stage I-IIA2 patients, after PSM (1:4), there was no significant difference in 5-year OS between the SCC group (n = 143) and the AC/ASC group (n = 34) (68.5% vs 67.8%, P = 0.175). However, the 5-year DFS in the SCC group was higher than that in the AC/ASC group (71.0% vs 55.7%, P = 0.045; HR = 2.037, P = 0.033). In stage IIB-IV patients, after PSM (1:4), the 5-year OS and DFS in the SCC group (n = 690) were higher than those in the AC/ASC group (n = 173) (70.7% vs 54.3% P < 0.001 vs 1.940%, P < 0.001 vs 45.8%, p < 0.001). CONCLUSIONS For stage I-IIA2, there was no significant difference in 5-year survival time, but patients with AC/ASC were more likely to relapse. In the more advanced IIB-IV stage, the oncological outcome of radical radiotherapy and chemotherapy of cervical AC/ASC was worse than that of SCC.

Abstract
This study aimed to assess neoadjuvant chemotherapy’s clinical outcomes such as efficacy, toxicity, and survival outcomes followed by radical hysterectomy ((NACT-RS) among women with cervical cancer stage IB3 and IIA2, by comparing concurrent chemoradiotherapy (CCRT) and NACT-RS. The study retrospectively reviewed patients with (2018 FIGO) stage IB3 and IIA2 cervical cancer who received preoperative neoadjuvant chemotherapy followed by NACT-RS or concurrent chemoradiotherapy (CCRT). The outcome measures were the 5-year survival and complication rates between the two groups. The median follow-up was 75 months. In total, 218 patients had stage IIA2, 136 patients had stage IB3, 201 patients received CCRT, and 153 patients received preoperative NACT-RS. In the CCRT group, the incidence of early complications (myelosuppression, gastrointestinal and urinary) was higher compared with that in the NACT-RS group (76.1 vs. 26.1%; p < 0.001, respectively). There was no significant difference between the two study groups concerning late complications. Five-year PFS was 79.9% and 85.5% in the NACT-RS and CCRT groups, respectively (p = 0.093). Five-year OS was 86.9% and 85.5% in the NACT-RS and CCRT groups, respectively (p = 0.97). In the multivariate clinicopathologic characteristics analysis for OS, initial tumor size > 4.3 cm (HR 5.11; p < 0.001), AC/ASC (HR 1.89; p = 0.02), histologic grade 2–3 (HR 2.25; p = 0.04), and 2018 FIGO stage IIA2 (HR 8.67; p < 0.001) were independent risk factors. The survival of patients with stage IB3 and IIA2 cervical cancer treated with NACT-RS was similar to that of patients treated with CCRT without increasing side effects.

Abstract
Aim This study aimed to identify the most effective treatment mode for locally advanced cervical cancer (LACC) by adopting a network meta-analysis (NMA). Methods Randomized controlled trials about treatments were retrieved from PubMed, Medline and Embase. Odds ratios (OR) of overall survival (OS) and progression-free survival (PFS) were calculated by synthesizing direct and indirect evidence to rank the efficacy of nine treatments. Consistency was assessed by node-splitting method. Begg's test was performed to evaluate publication bias. The surface under cumulative ranking curve (SUCRA) was also used in this NMA. Results A total of 24 eligible randomized controlled trials with 6,636 patients were included in our NMA. These trials compared a total of nine different regimens: radiotherapy (RT) alone, surgery, RT plus adjuvant chemotherapy (CT), concurrent chemoradiotherapy (CCRT), neoadjuvant CT plus CCRT, CCRT plus adjuvant CT, neoadjuvant CT, RT, CCRT plus surgery. Among those therapeutic modalities, we found that the two interventions with the highest SUCRA for OS and PFS were CCRT and CCRT plus adjuvant CT, respectively. ORs and 95% confidence interval (CI) for the two best strategies were CCRT versus CCRT plus adjuvant CT (OR, 0.84; 95% CI, 0.53-1.31) for OS, CCRT plus adjuvant CT versus CCRT (OR, 0.60; 95% CI, 0.38-0.96) for PFS. Conclusions This NMA supported that CCRT and CCRT plus adjuvant CT are likely to be the most optimal treatments in terms of both OS and PFS for LACC. Future studies should focus on comparing CCRT and CCRT plus adjuvant CT in the treatment of LACC. Systematic Review Registration PROSPERO, CRD42019147920.

Abstract
Objectives: With the use of concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC), survival outcomes are still not optimal. This study was designed to evaluate the efficacy and safety of adjuvant chemotherapy (ACT) for patients with LACC after treatment with CCRT. Methods: Patients diagnosed with stage IIA-IIIB LACC, were retrospectively analyzed. All patients received cisplatin-based CCRT and were divided into two groups: ACT after CCRT (CCRT + ACT group) and observation after CCRT (CCRT group). Overall survival (OS), progression-free survival (PFS) and adverse effects were recorded and analyzed. Results: In total, 375 patients were included; 262 patients accepted ACT after CCRT while the remaining 113 patients chose observation. With a median follow-up of 40 months, no significant differences were found in the OS rates for patients in the CCRT + ACT and CCRT groups at 1 year, 3 years and the end of follow-up. There was also no significant discrepancy in PFS between groups. Subgroup analysis showed the International Federation of Gynecology and Obstetrics (FIGO) stage and age had negligible influence on both OS and PFS. Acute adverse events (grades 3-4) happened more frequently in CCRT + ACT group than in the CCRT group, with significant differences in neutropenia, anemia and creatinine. Conclusion: ACT after CCRT did not show benefit in survival but did induce some adverse effects. Therefore, this regimen is not recommended unless further large-scale randomized controlled trials are executed.

[PMID: 35148230 DOI: 10.1080/01443615.2021.2012437] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/24/2022]
Abstract
To verify the role of consolidation chemotherapy after concurrent chemoradiotherapy for bulky and locally advanced cervical cancer, a meta-analysis was performed. Based on articles published up to Jun 2020 a literature search in PubMed, EMBASE and Cochrane Library was conducted to identify eligible studies. A total of 4 articles consisting of 1659 patients were enrolled. The pooled results revealed that overall survival (OS) of patients treated with consolidation chemotherapy after concurrent chemoradiotherapy (CCRT + CT) was significantly superior to concurrent chemoradiotherapy (CCRT) alone (HR = 0.78, 95% CI: 0.69-0.88, p < .0001). The meta-analysis reviewed that the progression-free survival rate (PFS) of patients treated with CCRT + CT was significantly superior to CCRT alone (HR = 0.80, 95% CI: 0.73-0.87, p < .00001). The pooled results revealed a significant reduction of local recurrence rate for the CCRT + CT group (RR = 0.66, 95% CI: 0.55-0.79, p < .00001). The pooled meta-analysis also showed a significant reduction of distant recurrence rate for the CCRT + CT group (RR = 0.55, 95% CI: 0.44-0.69, p < .00001). The pooled results of grade 3/4 bone marrow suppression were calculated as OR and presented with a 95% CI (OR = 15.85; 95% CI: 9.48, 26.5, p < .00001), indicating patients who received CCRT + CT are more likely to suffer 3/4 bone marrow suppression than those treated with CCRT alone. In conclusion, patients who received chemoradiation with consolidation chemotherapy showed a significantly longer PFS, longer OS, lower local recurrence rate and distant recurrence rate compared to traditional concurrent chemoradiotherapy.Impact statementWhat is already known on this subject? Since CCRT was recommended as the standard treatment for cervical cancer, there was still a 20-30% chance of local recurrence, and 18-25% of distant recurrence for cervical cancer patients. Aiming to completely eradicate potential undetected micrometastases, consolidation chemotherapy came into the area of interest. We conducted a meta-analysis to verify the role of consolidation chemotherapy in cervical cancer.What do the results of this study add? The addition of consolidation CT resulted in a longer overall survival rate (OS) and progression-free survival rate (PFS), mainly due to control of local and distant relapses, especially the latter one. Toxicity followed consolidation CT increased but still clinically manageable.What are the implications of these findings for clinical practice and/or further research? In the future, we need more clinical studies with high quality to verify the role of consolidation CT in cervical cancer, and further to optimise the criteria for it.

Abstract
The impact of histologic subtype on definitive radiotherapy for patients with locally advanced cervical cancer remains unclear. The aim of this retrospective analysis was to assess clinicopathological findings and clinical outcome by histological type in patients with stage IIB-IVA cervical cancer. Ninety-two patients with stage IIB-IVA [International Federation of Gynecology and Obstetrics (FIGO) 2008] cervical cancer, who underwent definitive radiotherapy between 2013 to 2018, were identified as eligible for this study. The clinical information of the eligible patients was obtained from medical records of our hospital. Seventy-eight patients underwent concurrent chemoradiotherapy, and the remaining 14 patients received radiotherapy alone. Of 92 patients, 83 had squamous cell carcinoma (SCC) and 9 had non-SCC histology. Progression-free survival (PFS) rate of patients with non-SCC was significantly worse than of those with SCC (2-year PFS: 62.0% vs. 12.5%, p = 0.0020), but overall survival (OS) rate did not statistically differ between the two subtypes (2-year OS: 82.4% vs. 62.5%, p = 0.2157). Pelvic failure-free (PFF) rate of patients with non-SCC histology was significantly worse than of those with non-SCC (2-year PFF; 88.2% vs. 25.0%, p < 0.0001). In univariate analysis, non-SCC histology was associated with PFS rate, although there was no association with OS rate. In multivariate analysis, non-SCC histology and lymph node metastasis were independent prognostic factors for shorter PFS. In patients with stage IIB-IVA cervical cancer who underwent definitive radiotherapy, patients with non-SCC showed significantly worse PFS rate than those with SCC.

Abstract
BACKGROUND Given the lack of primary and secondary prevention programs and cancer awareness in general, cervical cancer remains one of the main causes of cancer-related death in developing countries, such as Bosnia and Herzegovina. Optimization of combinations of external radiation therapy (ERT), brachytherapy and chemotherapy is still needed to improve outcomes in the treatment of advanced cervical cancer. PATIENTS AND METHODS We retrospectively analyzed 48 consecutive patients with Fédération Internationale de Gynecologie et d'Obstetrique (FIGO) 2009 stage IB2-IVA, who were treated with primary concomitant chemobrachyradiotherapy (CCBRT) and consolidation chemotherapy at the Department of Oncology, University Hospital Mostar, Bosnia and Herzegovina between December 2012 and June 2020. Patients were treated with ERT plus two cycles of concomitant chemobrachytherapy with ifosfamide and cisplatin and low-dose rate (LDR) brachytherapy followed by four cycles of consolidation chemotherapy at 3‑week intervals. We evaluated local control rate (LCR), disease-free survival (DFS), overall survival (OS), disease-specific survival (DSS) and toxicity. RESULTS After 45.5 months (interquartile range, IQR = 47 months) of median follow-up, 5‑year DFS was 72.8% (95% confidence interval. CI 59-78%), OS was 76.6% (95% CI 60-79%), and DSS was 88% (95% CI 71-86%) with acceptable toxicity. LCR was 94%. CONCLUSION Primary CCBRT and consolidation chemotherapy applied in standard clinical practice in the treatment of locally advanced cervical cancer (LACC) produce respectable outcomes.

Abstract
Objective We aimed to investigate the distinct transcriptional landscape in poor responders to concurrent chemoradiotherapy (CCRT) and to gain mechanistic insights into treatment resistance in cervical cancer. Methods RNA sequencing was performed in patients with locally advanced cervical cancer treated with platinum-based CCRT. Transcriptome data of no durable benefit (NDB; progression-free period <3 years) and durable clinical benefit (DCB; progression-free period >5 years) patients were compared. The NDB score was estimated for each patient using differentially expressed genes between NDB and DCB patients. The potential response to programmed death-1 blockade was estimated using the tumor immune dysfunction and exclusion (TIDE) score and T-cell-inflamed gene expression profile (GEP). Results NDB patients exhibited a distinct transcriptional profile compared to DCB patients, such as higher signatures of extracellular matrix organization and epithelial-to-mesenchymal transition. The fraction of cancer-associated fibroblasts (CAFs) within the tumor was significantly higher in NDB patients than in DCB patients. High NDB scores were significantly associated with poor survival in the Cancer Genome Atlas cervical cancer cohort (n=274; p=0.015) but only in patients who received curative aim radiotherapy (p=0.002). Patients with high NDB scores displayed significantly higher TIDE prediction scores and lower T-cell-inflamed GEP scores than those with low NDB scores. Conclusion Patients with cervical cancer having poor CCRT or RT outcomes exhibited a distinct gene signature that could predict treatment outcomes. For poor responders, immune checkpoint inhibitors may be less effective whereas CAF-targeting treatments may be a promising approach. • A subgroup of patients with locally advanced cervical cancer exhibit no durable benefit (NDB) after chemoradiotherapy. • NDB patients exhibited a distinct transcriptional profile • NDB signature score predicted poor outcome in independent cohorts. • NDB patients may have poor response to immune checkpoint blockade.

Abstract
Primary surgical management is successful as the sole therapeutic modality in the majority of women with early-stage cervical, vaginal and vulvar cancer, but the presence of certain risk factors in the surgico-pathological specimen indicates a poorer prognosis. Adjuvant treatment can improve overall survival in such cases. Important risk factors in cervical cancer include intermediate-risk factors (large tumor size, deep cervical stromal invasion, lymph-vascular space invasion) and high-risk factors (positive or close margins, lymph nodes, or parametrial involvement). In vulvar cancer, positive margins and lymph nodes are the two most important factors for adjuvant therapy. Radiation therapy has been the mainstay of adjuvant therapy in these cancers, supplemented by chemotherapy. Recent advances have witnessed the inclusion of newer therapeutic modalities such as immunotherapy. This review addresses the current status of various adjuvant therapeutic modalities for these gynecological cancers.

Abstract
The adjuvant and post-surgical treatment of gynaecological cancers has historically been guided by the estimation of relapse risk based on clinicopathological factors determined at the time of cancer diagnosis. The recent advancement of genomic and molecular characterisation of gynaecological cancers has begun to shift paradigms in the selection of adjuvant treatment strategy. Recent data regarding the predictive and/or prognostic value of molecular tests in the treatment of advanced ovarian cancer as well as early stage endometrial cancer have been the first such examples to enter adjuvant treatment guidelines for these diseases. In this article, we discuss the current state and future development of molecular assays for gynaecological cancers and how they impact upon treatment selection for ovarian, endometrial and cervical cancers in the post-surgical setting.

Abstract
Cervical cancer is one of the most common cancers in the world both in terms of incidence and mortality, more so important in low- and middle-income countries. Surgery and radiotherapy remain the backbone of treatment for non-metastatic cervical cancer, with significant improvement in survival provided by addition of chemotherapy to radiotherapy. Survival as well as quality of life is improved by chemotherapy in metastatic disease. Platinum-based chemotherapy with/without bevacizumab is the mainstay of treatment for metastatic disease and has shown improvement in survival. The right combinations and sequence of treatment modalities and medicines are still evolving. Data regarding the molecular and genomic biology of cervical cancer have revealed multiple potential targets for treatment, and several new agents are presently under evaluation including targeted therapies, immunotherapies and vaccines. This review discusses briefly the current standards, newer updates as well as future prospective approaches in systemic therapies for cervical cancer.

Abstract
Abstract
Introduction: Carcinoma cervix is the most common gynecological malignancy in India and a major cause of cancer mortality and morbidity in the females despite Concurrent chemoradiotherapy (CCRT). Attempts are on to improved overall survival by addition of adjuvant chemotherapy (ACT) to CCRT. Aim: The aim of this study is to establish toxicity profile of double-agent ACT after CCRT and ICRT in locally advanced cervical cancer (LACC) and to compare it with standard chemoradiation protocol. Materials and Methods: Patients were randomized into two arms: in conventional arm (Arm 1, n = 23), patients received a standard protocol of weekly injection cisplatin 40 mg/m2 concurrently with pelvic external beam radiotherapy (5040cGy/28 fractions) followed by ICRT (03 fractions of 7 Gy each). In interventional arm (Arm 2, n = 24), patients received CCRT/ICRT protocol; and were further offered ACT with three cycles of consolidation chemotherapy using injection paclitaxel and injection carboplatin every 3 weeks after CCRT and ICRT. Results: The incidence of anemia was 14/23 (50% Grade 1) in Arm 1 and 12/24 in Arm 2 (17% Grade 1, rest higher grade). In Arm 2, 37% of patients had ≥Grade 2 neuropathy and 16% of patients had Grade 1 alopecia, whereas nil incidence was reported in Arm 1 (P = 0.005 and 0.04, respectively). Grade 3 neutropenia was observed in 4/23 (17%) patients of Arm 1 and 8/24 patients (33%) of Arm 2. None of the patients in Arm 1 required indoor supportive care while 4/24 patients (17%) were managed as an indoor patient. Among late toxicities, in Arm 2, the incidence of Grade 2 and Grade 3 anemia was 42%, whereas in Arm 1, its incidence was 22%. In Arm 1, no patient exhibited features of neuropathy, whereas, in Arm 2, 12/24 (50%) of the patients had neuropathy (P value for these two late events was <0.05 statistically significant). No therapy-induced mortality was noted. Conclusion: Exhibition of ACT with injection Paclitaxel and injection carboplatin in locally advanced carcinoma cervix is a technically viable option with manageable toxicity.

Abstract
Neoadjuvant chemotherapy (NACT) remains an attractive alternative for controlling locally advanced cervical cancer. However, approximately 15-34% of women do not respond to induction therapy. To develop a risk stratification tool, 56 patients with stage IB-IIB cervical cancer are included in 2 research centers from the discovery cohort. Patient-specific somatic mutations led to NACT non-responsiveness are identified by whole-exome sequencing. Next, CRISPR/Cas9-based library screenings are performed based on these genes to confirm their biological contribution to drug resistance. A 15-gene classifier is developed by generalized linear regression analysis combined with the logistic regression model. In an independent validation cohort of 102 patients, the classifier showed good predictive ability with an area under the curve of 0.80 (95% confidence interval (CI), 0.69-0.91). Furthermore, the 15-gene classifier is significantly associated with patient responsiveness to NACT in both univariate (odds ratio, 10.8; 95% CI, 3.55-32.86; p = 2.8 × 10-5) and multivariate analysis (odds ratio, 17.34; 95% CI, 4.04-74.40; p = 1.23 × 10-4) in the validation set. In conclusion, the 15-gene classifier can accurately predict the clinical response to NACT before treatment, representing a promising approach for guiding the selection of appropriate treatment strategies for locally advanced cervical cancer.

Abstract
We aimed to assess the clinicopathological features and to determine the prognostic factors of cervical adenocarcinoma (AC). Relevant data were extracted from surveillance, epidemiology and end results database from 2004 to 2015. The log-rank test and Cox proportional hazard analysis were subsequently utilized to identify independent prognostic factors. A total of 3102 patients were identified. The enrolled patients were characterized by higher proportion of early FIGO stage (stage I: 65.9%; stage II: 14.1%), low pathological grade (grade I/II: 49.1%) and tumor size ≤ 4 cm (46.8%). The 5- and 10-year cancer-specific survival rates of these patients were 74.47% and 70.00%, respectively. Meanwhile, the 5- and 10-year overall survival (OS) rates were 71.52% and 65.17%, respectively. Multivariate analysis revealed that married status, surgery as well as chemotherapy were independent favorable prognostic indicators. Additionally, aged > 45, tumor grade III/IV, tumor size > 4 cm, advanced FIGO stage and pelvic lymph node metastasis (LNM) were unfavorable prognostic factors (all P < 0.01). Stratified analysis found that patients without surgery could significantly benefit from chemotherapy and radiotherapy. In addition, chemotherapy could significantly improve the survival in stage II–IV patients and radiotherapy could only improve the survival in stage III patients (all P < 0.01). Marital status, age, grade, tumor size, FIGO stage, surgery, pelvic LNM and chemotherapy were significantly associated with the prognosis of cervical AC.

Abstract
Introduction: Locally advanced cervical cancer (LACC) (International Federation of Gynecology and Obstetrics (FIGO) 2009/2018 - stages IB2-IVA/IB3-IVA, respectively) is treated using a multimodal approach that includes chemoradiotherapy followed by brachytherapy.Areas covered: This review provides an overview of the progress made over the past decade in the treatment of LACC. Prognostic factors, FIGO classification and the role of imaging staging will be discussed. Efficacy of external-beam radiotherapy, brachytherapy and chemotherapy will be detailed. Indications for para-aortic staging lymphadenectomy and adjuvant hysterectomy, as well as follow-up and special population, will be covered.Expert opinion: The initial workup is one of the most crucial steps in the optimal care of patients, which should be realized by a multidisciplinary expert team. With the implementation of modern conformal radiotherapy techniques, the local control rate has been optimized. Nevertheless, 40% of patients experience recurrence with distant metastasis and a dismal prognosis. Currently, a clear benefit of neo- and adjuvant chemotherapy has not been established. The future likely involves (1) improved selection of patients for whom treatment intensification is justified, (2) a combination of new drugs with chemoradiation that are currently being tested in trials, and (3) the development of tailored treatment based on molecular characteristics.

Abstract
Objective The aim of this study was to explore whether adjuvant chemotherapy could improve prognosis for cervical cancer patients with elevated pretreatment serum squamous-cell carcinoma antigen (SCC-Ag). Methods Propensity-score matching and inverse probability of treatment weighting (IPTW) were used to ensure balanced groups for patients with (arm A) and without adjuvant chemotherapy (arm B). All patients were treated between January 2012 and December 2014 at a single center. Study outcomes were disease-free survival (DFS) and overall survival (OS). Results In total, 81 patients were included in this study. By propensity-score matching, 35 patients were included in each group (arm A and arm B). Median follow-up was 60 months in arm A and 66 months in arm B. Overall, 85.7% of patients in arm A and 71.4% of those in arm B received adjuvant radiotherapy. DFS and OS curves were similar between arms A and B (P=0.971 and 0.633, respectively). With IPTW, arm A was not associated with prognosis in terms of DFS (HR 0.946, 95% CI 0.237–3.784; P=0.938) or OS (HR 1.020, 95%CI 0.357–2.913; P=0.970). Conclusion For patients with elevated pretreatment SCC-Ag, adjuvant chemotherapy was not found to improve prognosis. Also, a considerable proportion of these patients had postoperative indications for adjuvant radiotherapy. For these cervical cancer patients with elevated pretreatment SCC-Ag, the choice of radical hysterectomy and adjuvant chemotherapy should be prudent.

Survival outcomes of neoadjuvant chemotherapy-related strategies compared with concurrent chemoradiotherapy for locally advanced cervical cancer: a meta-analysis of randomized controlled trials. Arch Gynecol Obstet 2021; 304:485-493. [PMID: 33389099 DOI: 10.1007/s00404-020-05916-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Accepted: 11/20/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE The survival benefits of neoadjuvant chemotherapy (NAC) compared with those of concurrent chemoradiotherapy (CRT) for locally advanced cervical cancer (LACC) patients remain uncertain. Meta-analysis was used to compare NAC and CRT. METHODS A systematic search was performed up to 9 September 2020. Survival outcomes were analyzed based on event frequency or hazard ratios (HRs). Multilevel mixed-effects logistic regression was applied to analyze the effect of regimen variables on survival outcomes. RESULTS Analysis based on Cox regression showed that CRT was better than NAC + radical hysterectomy (RT) (HR 1.25; 95% confidence interval (CI)) 1.02-1.54; p = 0.034) in terms of overall survival (OS). According to multilevel mixed-effects model analysis comparing NAC + RT and CRT, LACC patients who used cisplatin instead of carboplatin had a better Progression-free survival (PFS) (odds ratio (OR) 1.54; 95% CI 1.08-2.20; p = 0.016). When NAC + CRT and CRT were compared, gemcitabine administration was associated with a decrease in PFS (OR 0.47; 95% CI 0.22-0.99; p = 0.047). Increased doses of cisplatin and paclitaxel were associated with survival improvement. CONCLUSION Based on traditional meta-analysis, CRT was better than NAC + RT in terms of OS. Carboplatin instead of cisplatin as part of the NAC + RT strategy or gemcitabine use in NAC + CRT may not be a good choice. An increased total dosage of paclitaxel and/or cisplatin as part of NAC + CRT and CRT strategies may improve the survival outcome of LACC patients.

Abstract
Purpose The purpose of the study is to summarize the clinical characteristics and identify the prognosis of clear cell adenocarcinoma of the uterine cervix (CCAUC) in patients without a history of diethylstilbestrol (DES) exposure. Methods Forty-two patients with CCAUC, treated initially at Sun Yat-sen University Cancer Center between 1985 and 2017, were studied. Results Of all the CCAUC patients, the median age was 47 years old, and the median tumor size was 3 cm. Thirty-four early stage patients (IB = 28, IIA = 6) underwent radical surgery. Eight advanced stage patients (IIB = 8) received concurrent chemoradiotherapy (n = 4) or radical surgery (n = 4). Survival analysis showed that patients with early stage (IB-IIA) had a significantly better 5-year progression-free survival (PFS) and overall survival (OS) than those with advanced stage (IIB) (p < 0.05). The patients with negative pelvic lymph node (PLN) had a significantly better 5-year PFS and OS than those with positive PLN (p < 0.05). Radiotherapy (RT) did not affect PFS or OS in early stage patients with intermediate risk factors (p > 0.05). Adjuvant chemotherapy (CT) did not affect PFS or OS in early stage patients without risk factors (p > 0.05). Conclusion The FIGO stage and pelvic node status were important prognostic factors for both PFS and OS. For treatment modality, we recommended that radical surgery alone was used in early stage patients without high risk factors. Ovarian preservation in early stage patients involved some risk.

Prognostic Significance of Tumor Regression Rate during Concurrent Chemoradiotherapy in Locally Advanced Cervix Cancer: Analysis by Radiation Phase and Histologic Type. J Clin Med 2020; 9:jcm9113471. [PMID: 33126569 PMCID: PMC7692078 DOI: 10.3390/jcm9113471] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 10/20/2020] [Accepted: 10/26/2020] [Indexed: 11/17/2022] Open
Abstract
This study aimed to evaluate the prognostic significance of tumor regression rate according to radiation phase and histologic subtype in patients with locally advanced cervical cancer (LACC) treated with chemoradiation. We retrospectively reviewed the medical records of 398 patients with FIGO stage IIB-IVA cervical cancer treated with concurrent chemoradiotherapy (CCRT) between 2001 and 2019. Tumor response was assessed using serial magnetic resonance imaging (MRI) at three time points: pre-treatment, post-external beam radiotherapy (EBRT), and post-intracavitary radiotherapy (ICR). Tumor regression pattern according to histologic subtype and radiation phase (EBRT and ICR) was evaluated. Overall survival (OS) and progression-free survival (PFS) were the primary outcomes. Of 398 patients, 44 patients had adenocarcinoma/adenosquamous carcinoma (AC/ASC) and 354 patients had squamous cell carcinoma (SCC). AC/ASC was associated with significantly worse PFS and OS than SCC (p < 0.001). AC/ASC had a relatively poorer regression rate in response to EBRT than SCC (p < 0.001), whereas there was no significant difference in overall tumor regression rate after completion of RT (EBRT and ICR) between the two histologic subtypes. Multivariable analysis demonstrated AC/ASC histology to be an independent prognostic factor of decreased PFS and OS. Moreover, tumor regression rate after completion of EBRT (post-EBRT tumor regression rate (EBRTregression ≤ 26%) and proportion of tumor regression during EBRT to overall tumor regression (EBRTproportion ≤ 40%) were independent predictors of poor survival in patients with LACC. Tumor regression pattern of LACC in response to CCRT differs according to histologic subtype. AC/ASC histology and poor tumor response to EBRT are independent prognostic factors for worse survival in patients with LACC. Further studies are needed to develop a CCRT protocol that is specialized for patients with AC/ASC.

Abstract
INTRODUCTION This study aimed to compare the cost utility of concurrent chemoradiation (CCRT) to CCRT followed by adjuvant chemotherapy (CCRT/ACT) in locally advanced cervical cancer (LACC) using provider and societal viewpoints. METHODS Data from our trial which was a multi-centre study evaluating the efficacy of ACT compared to CCRT/ACT were entered into a decision tree model. The data included clinical probability, direct medical and non-medical costs, and utility obtained from the patients. The total cost, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) were estimated for a time horizon of 3 years. All costs and outcomes were discounted at 3% annually. RESULTS The cost of CCRT and CCRT/ACT was approximately 3,058 and 6,896 USD and 4,309 and 7,480 USD from provider and from societal viewpoints, respectively. The QALYs for CCRT and CCRT/ACT were 2.31480 and 2.32045, respectively. The ICER was 569,575 USD per QALY. For stage III-IVA LACC, the ICER was 28,050 USD per QALY. In the sensitivity analysis, the cost of ACT was the most significant influential parameter on the ICER. The ICER would be 0.26-fold lower if the cost of ACT was reduced by 25%. At the current ceiling threshold of 5,000 USD/QALY, CCRT had a 100% probability of being the best option. CONCLUSIONS In the Thai context, CCRT is more cost effective than CCRT/ACT for stage IIB-IVA LACC. CCRT/ACT may be considered only for stage III-IVA LACC because it has a lower ICER than other types of LACC.

Int J Gynecol Cancer 2020; 30:1434-1443. [PMID: 32788263 DOI: 10.1136/ijgc-2020-001351] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 06/23/2020] [Accepted: 06/25/2020] [Indexed: 12/24/2022] Open
Abstract
Para-aortic lymph node status at initial assessment is the most important prognostic factor and a key point for the therapeutic strategy in patients with locally advanced cervical cancer. Undiagnosed lymph node metastasis is a major clinical problem as the finding of positive para-aortic lymph nodes leads to treatment modification, with a possible impact on disease free survival. When aortic lymph node disease is discovered, radiotherapy is extended to the para-aortic area, and other treatment modalities may be considered. Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) is the most accurate imaging examination to assess para-aortic extension in patients with locally advanced cervical cancer. The gold standard to identify para-aortic extension remains histologic evaluation of the lymph nodes. Indeed, PET/CT fails to detect approximately 10-15% of patients with negative PET/CT aortic nodes who have lymph node metastasis on pathologic staging. Patients with positive pelvic lymph nodes have para-aortic extension in 25-30% of cases, and surgical staging will lead to treatment modification and probably to improved para-aortic and distant control. Surgical staging also avoids unnecessary toxicity associated with extended field radiation in approximately 75% of patients with pelvic lymph node metastasis. The best modality to identify para-aortic extension is histological evaluation of the lymph nodes, but the survival benefit of surgical staging remains controversial. On the other hand, current studies include a majority of patients without pelvic lymph node spread, who are likely to be those who will benefit the least from surgical staging.

Yuan Y, You J, Li X, Wang W. Adjuvant chemotherapy after radiotherapy or concurrent chemoradiotherapy for pelvic lymph node-positive patients with locally advanced cervical cancer: a propensity score matching analysis. Int J Gynecol Cancer 2020; 32:21-27. [DOI: 10.1136/ijgc-2020-001230] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 05/08/2020] [Accepted: 05/11/2020] [Indexed: 12/24/2022] Open
Abstract
ObjectiveThe benefit of adjuvant chemotherapy after definitive chemoradiotherapy in patients with pelvic lymph node-positive cervical cancer has been poorly studied. This study aimed to test the hypothesis that the addition of adjuvant chemotherapy to definitive radiotherapy or concurrent chemoradiotherapy improves survival in patients with pelvic lymph node-positive cervical squamous cell carcinoma.MethodsThis retrospective study enrolled patients with stage IB–IVA pelvic lymph node-positive cervical squamous cell carcinoma, without para-aortic lymph node metastases and initially treated with definitive radiotherapy or concurrent chemoradiotherapy between March 2007 and February 2018. Patients were classified into the adjuvant chemotherapy (5-fluorouracil or paclitaxel, plus cisplatin) and no-adjuvant chemotherapy groups. Treatment outcomes were compared between the two groups before and after 1:1 ratio propensity score matching.ResultsMedical records of 951 patients were reviewed and 792 patients were excluded. Finally, 159 patients were enrolled for analysis. Of these, 42 patients received a median of two cycles (range, 1–6) of adjuvant chemotherapy and 117 patients under observation after primary treatment. The median follow-up period was 33.8 months (range, 2.9–113.0). Before propensity score matching, no significant difference was observed in survivals between the two groups (P>0.05). After propensity score matching, 37 pairs of patients were selected. The 3-year rates of progression-free survival, overall survival, local control, and distant metastasis-free survival in the adjuvant chemotherapy and no-adjuvant chemotherapy groups were 80.2% and 60.4% (P=0.07), 83.0% and 63.7% (P=0.17), 94.0% and 81.9% (P=0.12), and 85.9% and 60.1% (P=0.04), respectively. The incidences of grade 3–4 acute and late toxicities were comparable between the two groups (P>0.05).DiscussionAdjuvant chemotherapy significantly improved 3-year distant metastasis-free survival in patients with pelvic lymph node-positive cervical squamous cell carcinoma. Further prospective studies are needed to provide supportive evidence for the therapeutic efficacy of adjuvant chemotherapy.

Arch Gynecol Obstet 2020; 301:1247-1255. [PMID: 32221709 PMCID: PMC7181442 DOI: 10.1007/s00404-020-05505-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Accepted: 03/12/2020] [Indexed: 02/01/2023]
Abstract
PURPOSE This retrospective study compared the efficacy and survival of patients with cervical adenocarcinoma (IB2/IIA2; FIGO2009) treated with neoadjuvant chemotherapy before radical surgery (NACT + RS), neoadjuvant chemoradiation therapy before radical surgery (NACRT + RS), or primary radical surgery (RS). METHODS Between January 2008 and November 2015, 91 patients diagnosed with stage IB2/IIA2 cervical adenocarcinoma were enrolled, including 29 patients who received RS, 24 patients who received NACT + RS, and 38 patients who received NACRT + RS. RESULTS The characteristics of patients were balanced among the three groups, and the median follow-up time was 72 months. The 5 year disease-free survival (DFS) rate was 75.8% and the 5 year overall survival (OS) rate was 85.0%. Univariate analysis revealed that effectiveness of neoadjuvant treatment, tumor size, lymph node metastases, and depth of stromal invasion were the factors predicting recurrence and mortality. Multivariate Cox proportional analysis revealed that the occurrence of a lymph node metastasis was an independent prognostic factor of DFS (hazard ratio [HR] = 0.223; 95% confidence interval [CI]: 0.060-0.827) and OS (HR = 0.088; 95% CI: 0.017-0.470). On survival analysis of preoperative adjuvant chemotherapy and primary surgery, the 5 year OS (P = 0.010) and DFS (P = 0.016) rates for the NACRT + RS group were significantly lower than those for the RS group. CONCLUSION Stage IB2/IIA2 cervical adenocarcinoma patients who received primary RS had a better DFS and OS than those who received preoperative NACRT. There was no significant difference when compared to the preoperative NACT group.

Abstract
INTRODUCTION Standard treatment for locally advanced cervical cancer (LACC) includes concomitant chemoradiotherapy (CRT) that typically controls localized disease. However, most patients develop distant metastasis, ultimately leading to death. OBJECTIVE To determine the role of adjuvant carboplatin and paclitaxel for clinical outcomes in patients with LACC. METHODS Between 2010 and 2017, 109 patients with LACC were retrospectively evaluated. All patients received cisplatin (40 mg/m2) with concurrent external-beam radiotherapy (up to 50.4 Gy), followed by intra-cavitary brachytherapy. Forty-six of 109 patients received a median of six cycles (range 3-6 cycles) of adjuvant chemotherapy consisting of paclitaxel (175 mg/m2) and carboplatin (CRT + chemotherapy group; area under the curve 5). The remaining 63 patients did not receive adjuvant chemotherapy (CRT group). RESULTS Disease-free survival and overall survival after a median follow-up of 24.5 months (range 2.6-94.75 months) were 93.5% and 95.7% and 69.8% and 82.5 % for the CRT + chemotherapy and CRT groups, respectively (p = 0.001, p = 0.012, respectively). No acute grade 3/4 gastrointestinal or genitourinary toxicities were seen during CRT. During adjuvant chemotherapy, the most troublesome side effects were hematologic and neurologic toxicities; however, most were manageable. No chronic grade 3/4 genitourinary toxicities were seen. DISCUSSION Adjuvant chemotherapy in patients with LACC significantly improved both disease-free survival and overall survival without increasing unmanageable toxicity. Future larger prospective trials are warranted to verify these findings.

Abstract
INTRODUCTION The role of adjuvant chemotherapy after radical radiotherapy (RT) or chemoradiotherapy (CRT) in cervical cancer awaits further confirmation. Evidences have shown that persistent human papilloma virus (HPV) DNA in exfoliated cell post-RT is a potential biomarker of subclinical residual disease and thus increases the risk of recurrence. In this prospective, multicentre, randomised controlled trial, we will use HPV DNA in exfoliated cell to identify patients with cervical cancer who received definitive RT or CRT with higher risk of relapse for adjuvant chemotherapy. METHODS AND ANALYSIS Eligible patients with histologically confirmed cervical cancer stage IIA2 to IVA of the International Federation of Gynaecology and Obstetrics, adequate organ function and no locoregional disease or distant metastasis after completion of primary treatment will be screened for HPV DNA in exfoliated cell at 1 month post-RT. Patients with undetectable HPV DNA will undergo standard surveillance. Patients with detectable HPV DNA will be randomly assigned to either adjuvant chemotherapy with docetaxel and nedaplatin for four cycles (arm 1) or observation (arm 2). Patients will be stratified for primary treatment (RT vs CRT). The primary endpoint is relapse-free survival. ETHICS AND DISSEMINATION This protocol received a favourable ethical opinion from the Ethics Committee of the Second Affiliated Hospital of Fujian Medical University on 6 February, 2018, (No. 28). The trial results will be published in peer-reviewed journals and presented in conferences. A summary of the findings will be made available to participants. TRIAL REGISTRATION NUMBER ChiCTR-IIR-17012655; Pre-results.

Abstract
This study aimed to evaluate the treatment outcomes of patients who received high-dose-rate intracavitary brachytherapy (HDR-BT) using Iridium-192 with or without external beam radiotherapy as definitive treatment for recurrent cervical cancer after hysterectomy. Thirty-six patients with local recurrence after hysterectomy received radiotherapy including HDR-BT from 2005 to 2013. Overall survival, local control rate, and progression-free survival were estimated retrospectively via the Kaplan-Meier method. Late adverse events were also scored using the Common Terminology Criteria for Adverse Events (version 3.0). Median follow-up time was 38 (range, 7.4–101.3) months. The 3-year estimates of overall survival, local control rate, and progression-free survival were 100.0%, 82.8%, and 76.8%, respectively. Two patients (5.6%) had grade 2 lymphedema, but no other adverse events greater than grade 2 were reported. In conclusion, HDR-BT was an effective treatment modality for patients with cervical cancer recurrence in the vaginal stump.

Abstract
INTRODUCTION This study was to evaluate the surgical and survival effects of neoadjuvant chemotherapy (NAC) followed by radical hysterectomy (RH) for cervical cancer with stages IB2 to IIB of FIGO 2009 staging. METHODS From February 2, 2001 to November 11, 2015, 428 patients received NAC followed by RH in a tertiary hospital, in which all the major procedures were performed by one surgeon. Surgical and survival outcomes were evaluated between the NAC and primary RH groups. RESULTS A total of 279 (65.2%) patients received NAC, and the overall clinical and complete pathological response rates were 65.9% and 10.8%, respectively. Compared with primary RH patients, NAC patients had more advanced stages, higher recurrence rate, longer median duration of RH, and more median estimated blood loss. After adjusted with baseline risk factors, no significant differences in progression-free or overall survival were observed between the NAC and primary RH groups. However, the responders to NAC had better survival outcomes. CONCLUSIONS There were no surgical or survival benefits of NAC for patients with cervical cancer of stages IB2 to IIB except for the responders to NAC.

Abstract
Objective To compare response rate and survivals of locally advanced stage cervical cancer patients who had standard concurrent chemoradiation therapy (CCRT) alone to those who had adjuvant chemotherapy (ACT) after CCRT. Methods Patients aged 18–70 years who had International Federation of Gynecology and Obstetrics stage IIB–IVA without para-aortic lymph node enlargement, Eastern Cooperative Oncology Group scores 0–2, and non-aggressive histopathology were randomized to have CCRT with weekly cisplatin followed by observation (arm A) or by ACT with paclitaxel plus carboplatin every 4 weeks for 3 cycles (arm B). Results Data analysis of 259 patients showed no significant difference in complete responses at 4 months after treatment between arm A (n=129) and arm B (n=130): 94.1% vs. 87.0% (p=0.154) respectively. With the median follow-up of 27.4 months, 15.5% of patients in arm A and 10.8% in arm B experienced recurrences (p=0.123). There were no significant differences of overall or loco-regional failure. However, systemic recurrences were significantly lower in arm B than arm A: 5.4% vs. 10.1% (p=0.029). The 3-year progression-free survival (PFS) and 3-year overall survival (OS) of the patients in both arms were not significantly different. The hazard ratio of PFS and OS of arm B compared to arm A were 1.26 (95% CI=0.82–1.96; p=0.293) and 1.42 (95% CI=0.81–2.49; p=0.221) respectively. Conclusions ACT with paclitaxel plus carboplatin after CCRT did not improve response rate and survival compared to CCRT alone. Only significant decrease of systemic recurrences with ACT was observed, but not overall or loco-regional failure.

Abstract
OBJECTIVE This retrospective study aimed to compare prognostic factors and survival between adenocarcinoma (AC) and squamous cell carcinoma (SCC) in locally advanced cervical cancer treated at a single center. METHODS All medical records of cervical cancer patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIB or IIIA,B, treated between 2004 and 2012, were reviewed. We treated patients with chemoradiotherapy (CRT) followed by brachytherapy (BT). Multivariate logistic regression and Cox proportional hazard models were used to analyze clinicopathological characteristics, patterns of care and outcomes. RESULTS We included in the analysis 161 patients (52 AC; 109 SCC). Patients with AC were younger (age 50 vs. 55 years), more likely to die from the disease (HR: 1.60; 95% CI: 1.26-2.58; p = .001) and to have disease recurrence (HR: 1.69; 95% C.I: 1.21-2.12; p = .004) than those with SCC. The other significant prognostic factors for overall survival (OS) and recurrence-free survival (RFS) in AC were FIGO stage (p = .001; p = .002), WHO status (0 vs. 1-3; p = .003; p = .04), and hemoglobin level (<12 g/dl>; p = .04; p = .02). The 5 year overall survival for stage II of AC and SCC was 63% and 82% (p = .03), and for IIIA,B it was 33.6% and 73% (p = .0005). The 5 year RFS for AC and SCC stage FIGO IIIA,B was 24% and 57% (p = .001). CONCLUSIONS Adenocarcinoma histology negatively impacts OS and RFS for advanced cervical cancer. Histology-specific therapy may be an opportunity for survival improvement in these women.

The Impact of Addition of Consolidation Chemotherapy to Standard Cisplatin-Based Chemoradiotherapy in Uterine Cervical Cancer: Matter of Distant Relapse. JOURNAL OF ONCOLOGY 2019; 2019:1217838.

Abstract
BACKGROUND Treatment of advanced uterine cervical cancer has advanced little in the last 15 years. Although two phase III trials showed survival benefit with the addition of consolidation chemotherapy (CT) after cisplatin-based chemoradiotherapy (RTCT), it is not considered standard of care. We aimed to evaluate the benefit of consolidation CT compared to no additional treatment in patients treated with RTCT. METHODS This is a retrospective study including 186 patients with FIGO stage IB2, IIA2, or IIB to IVB (paraaortic lymph nodes only) uterine cervical cancer who were treated with standard RTCT alone or RTCT followed by consolidation CT. Overall survival (OS), progression free survival (PFS), and the risk of distant and local relapses were compared between the two treatment groups. RESULTS At 3 years OS was 91% versus 82.3% (p=0.027), PFS 84.3% versus 54.4% (p=0.047), and distant metastasis free survival (DMFS) 80.4% versus 62.5% (p=0.027) in favor of the consolidation CT group. Multivariate analysis confirmed the benefit of consolidation CT. There was no difference in locoregional free survival (LRFS). Positive lymph node was related to a higher risk of distant relapse. In the lymph node positive subgroup consolidation CT resulted in longer OS (p=0.050), PFS (p=0.014), and DMFS (p=0.022); in the lymph node negative subgroup there was no benefit from consolidation CT. CONCLUSIONS Use of consolidation CT resulted in longer OS and PFS, mostly due to control of distant relapses. Patients at higher risk of distant relapse showed the greatest benefit. This data generates a hypothesis that could help to better select patients to consolidation CT.

Abstract
OBJECTIVE Despite the benefits of concomitant radiotherapy and cisplatin for locally advanced cervical cancer, recurrence rates remain high. New treatment strategies such as consolidation chemotherapy and different concomitant chemotherapy combinations have been tested in recent years. Identification of the best candidates for each treatment strategy could optimize results. STUDY DESIGN A retrospective review of data from 127 patients with locally advanced cervical cancer (International Federation of Gynecology and Obstetrics Stages IIB-IVA), treated at a single institution from 2005 to 2014. Risk factors for loco-regional and systemic recurrence, and prognostic factors for overall survival (OS) were analysed using Cox regression. Survival of patients treated with consolidation chemotherapy was compared with survival of patients not treated with consolidation chemotherapy in the role cohort and in a propensity-score-matched cohort. RESULTS With a median follow-up time of 48.7 months, loco-regional-recurrence-free survival (LRFS), distant-metastasis-free survival (DMFS) and OS at 5 years were 76.6%, 54.0% and 63.0%, respectively. On multivariate analysis, tumour size ≥6 cm was associated with shorter LRFS [hazard ratio (HR) 5.18; 95% confidence interval (CI) 1.45-18.45; p = 0.011], and adenocarcinoma (HR 2.48; 95% CI 1.10-5.57; p = 0.028) and positive lymph nodes (HR 2.21; 95% CI 1.303-4.72; p = 0.041) were associated with shorter DMFS. Tumour size ≥6 cm was associated with shorter OS (HR 2.64; 95% CI 1.09-6.35; p = 0.031). Twenty-two patients were treated with consolidation chemotherapy; on univariate analysis, these patients had longer OS compared with patients who were not treated with consolidation chemotherapy (p = 0.043). In a propensity-score-matched cohort, patients treated with consolidation chemotherapy had longer DMFS and OS compared with patients who were not treated with consolidation chemotherapy, although the difference was not significant. CONCLUSIONS Different risk factors are associated with loco-regional and distant metastases in patients with locally advanced cervical cancer, and could potentially lead to particular therapeutic strategies. Although the number of patients treated with consolidation chemotherapy in the study cohort was small, they seemed to live longer and to have better control of distant relapse then patients who were not treated with consolidation chemotherapy.
