Prognostic value of HPV circulating tumor DNA detection and quantification in locally advanced cervical cancer. Front Oncol 2024; 14:1382008. [PMID: 39040450 PMCID: PMC11260666 DOI: 10.3389/fonc.2024.1382008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 06/17/2024] [Indexed: 07/24/2024] Open
Abstract
Background Cervical cancers are mainly caused by an oncogenic HPV. For locally advanced stages, the standard treatment is radio-chemotherapy (RTCT) followed by brachytherapy. Nevertheless, the prognosis remains highly heterogeneous between patients. Objective We investigated the prognostic value of HPV circulating tumor DNA (ctDNA) in locally advanced cervical cancers alongside that of Squamous Cell Carcinoma Antigen (SCC-A). Methods This single-center retrospective study included patients treated in curative intent for an IB3 to IVA squamous cell cervical cancer. Quantification of HPV ctDNA in serum collected at diagnosis was performed using a multiplex digital PCR assay for the simultaneous detection of 8 HPV genotypes. Results Among the 97 patients included, 76 patients (78.4%) were treated by RTCT, followed by brachytherapy for 57 patients (60%). HPV ctDNA was detected in 59/97 patients at diagnosis (60.8%). This detection was associated with lymph node invasion (p=0.04) but not with tumor stage. A high level of SCC-A at diagnosis was associated with tumor stage (p=0.008) and lymph node invasion (p=0.012). In univariate analysis, better disease-free survival (DFS) was associated with optimal RTCT regimen (p=0.002), exposure to brachytherapy (p=0.0001) and a low SCC-A at diagnosis (continuous analysis, p=0.002). Exploratory analysis revealed that 3/3 patients (100%) whose HPV ctDNA was still detectable at the end of treatment relapsed, while 6/22 patients (27.3%) whose HPV ctDNA was negative at the end of treatment relapsed. Conclusion HPV ctDNA detection at diagnosis of locally advanced cervical squamous cell carcinomas is frequent and related to node invasion, but not to DFS. The prognostic value of HPV ctDNA detection after treatment warrants specific studies.

Evaluation of the toxicity of prophylactic extended-field radiation therapy with volumetric modulated arc therapy in combination with concomitant chemoradiotherapy in patients with locally advanced stage IIIC1r cervical cancer according to the 2018 FIGO classification. Rep Pract Oncol Radiother 2024; 29:42-50. [PMID: 39165598 PMCID: PMC11333078 DOI: 10.5603/rpor.99353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 02/05/2024] [Indexed: 08/22/2024] Open
Abstract
Background To evaluate the toxicity of prophylactic extended-field radiation therapy (EFRT) combined with volumetric modulated arc therapy (VMAT) in combination with cisplatin chemotherapy for locally advanced stage IIIC1r cervical cancer [2018 International Federation of Gynecology and Obstetrics (FIGO)]. Materials and methods Thirty patients with stage IIIC1r cervical cancer were treated with EFRT combined with concurrent cisplatin. Acute toxicities were evaluated according to the common terminology criteria for adverse events (CTCAE v.5). Delayed toxicities were evaluated according to the classification criteria of radiation damage toxicity of the Radiation Therapy Oncology Group (RTOG). The efficacy of the regimens was evaluated using response evaluation criteria in solid tumors (RECIST v1.1). Spearman correlation was used to analyze the correlation between acute gastrointestinal toxicity (nausea) and the small bowel V45. Predictive value analysis was performed using a receiver operating characteristic (ROC) curve. Results There were no grade ≥ 3 acute toxicities. The most common acute toxicity observed was nausea (grade 2 in 40%), which was positively correlated with the volume of the small intestine receiving 45 Gy. When the V45 of the small intestine was > 83.2 cc, the risk of grade 2 acute upper digestive tract toxicity (nausea) increased. The major late toxicities had the following distributions: Grade 1 diarrhea, 36.7%; Grade 1 abdominal pain, 13.3%; and Grade 1 radiation cystitis. No grade ≥ 2 late toxicities were observed. Conclusions Treatment of locally advanced stage IIIC1r cervical cancer with EFRT combined with VMAT and concurrent cisplatin chemotherapy was well tolerated, and the acute toxicity profile was acceptable. Significant grade 3 acute/delayed toxicities were not observed.

Treatment Strategies Guided by [18F]FDG-PET/CT in Patients with Locally Advanced Cervical Cancer and [18F]FDG-Positive Lymph Nodes. Cancers (Basel) 2024; 16:717. [PMID: 38398108 PMCID: PMC10887300 DOI: 10.3390/cancers16040717] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/22/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Modern treatment guidelines for women with advanced cervical cancer recommend staging using 2-deoxy-2-[18F]fluoro-D-glucose positron emission computed tomography ([18F]FDG-PET/CT). However, the risk of false-positive nodes and therapy-related adverse events requires caution in treatment planning. Using data from the Netherlands Cancer Registry (NCR), we estimated the impact of [18F]FDG-PET/CT on treatment management in women with locally advanced cervical cancer, i.e., on nodal boosting, field extension, and/or debulking in cases of suspected lymph nodes. METHODS Women diagnosed between 2009 and 2017, who received chemoradiotherapy for International Federation of Gynaecology and Obstetrics (2009) stage IB2, IIA2-IVB cervical cancer with an [18F]FDG-positive node, were retrospectively selected from the NCR database. Patients with pathological nodal examination before treatment were excluded. The frequency of nodal boosting, extended-field radiotherapy, and debulking procedures applied to patients with [18F]FDG-positive lymph nodes was evaluated. RESULTS Among the 434 eligible patients with [18F]FDG-positive nodes, 380 (88%) received interventions targeting these lymph nodes: 84% of these 380 patients received nodal boosting, 78% extended-field radiotherapy, and 12% debulking surgery. [18F]FDG-positive nodes in patients receiving these treatments were more likely to be classified as suspicious than inconclusive (p = 0.009), located in the para-aortic region (p < 0.001), and larger (p < 0.001) than in patients who did not receive these treatments. CONCLUSION While existing guidelines advocate [18F]FDG-PET/CT-guided treatment planning for the management of advanced cervical cancer, this study highlights that not all cases of [18F]FDG-positive nodes received an intervention, possibly due to the risk of false-positive results. Improvement of nodal staging may reduce suboptimal treatment planning.

Prophylactic Extended-Field Irradiation Versus Pelvic Irradiation in Patients With Cervical Cancer With 2018 FIGO Stage IIIC1 Disease. Pract Radiat Oncol 2023; 13:e409-e415. [PMID: 37075837 DOI: 10.1016/j.prro.2023.03.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 03/14/2023] [Accepted: 03/14/2023] [Indexed: 04/21/2023]
Abstract
PURPOSE The aim of this study was to compare the survival rates and toxicities of prophylactic extended-field radiation therapy (EFRT) and pelvic radiation therapy (PRT) among patients with cervical cancer with 2018 International Federation of Gynecology and Obstetrics (FIGO) stage IIIC1 disease. METHODS AND MATERIALS We retrospectively analyzed patients with 2018 FIGO stage IIIC1 disease who were treated with definitive concurrent chemoradiotherapy at our institute between 2011 and 2015. A dose of 50.4 Gy in 28 fractions was delivered to the pelvic region (by PRT) or the pelvic plus para-aortic lymph node region (by EFRT) with intensity modulated radiation therapy. The first-line regimen of concurrent chemotherapy was weekly cisplatin. RESULTS A total of 280 patients were included, with 161 patients treated with PRT and 119 patients treated with EFRT. After propensity score matching (1:1), 71 pairs of patients were selected. The respective 5-year rates of the patients treated with PRT and EFRT were 61.9% and 85.0% for overall survival (P = .025) and 53.0% and 77.9% for disease-free survival (DFS) (P = .004), respectively, after matching. In the subgroup analysis, patients were grouped into a high-risk group (122 patients) and a low-risk group (158 patients) based on 3 factors: positive common iliac lymph nodes, ≥3 pelvic lymph nodes, and 2014 FIGO stage IIIB disease. In both the high-risk and low-risk groups, EFRT significantly improved DFS compared with PRT. The rates of grade ≥3 chronic toxicities were 1.2% and 5.9% in the PRT and EFRT groups, respectively (P = .067). CONCLUSIONS In comparison to PRT, prophylactic EFRT was associated with improved overall survival, DFS, and para-aortic lymph node control in patients with cervical cancer with FIGO stage IIIC1 disease. The incidence of grade ≥3 toxicities was higher in the EFRT group than in the PRT group, although the difference was not significant.

Abstract
PURPOSE To discuss the dosimetric advantages and reliability of the accurate delivery of online adaptive radiotherapy(online ART) for uterine cervical cancer(UCC). METHODS AND MATERIALS Six UCC patients were enrolled in this study. 95% of the planning target volume (PTV) reached 100% of the prescription dose (50.4 Gy/28fractions/6weeks) was required. The patients were scanned with uRT-Linac 506c KV-FBCT then the target volume (TV) and organs at risk (OARs) were delineated by doctors. The dosimeters designed and obtained a routine plan (Plan0). KV-FBCT was used for image guidance before subsequent fractional treatment. The online ART was processed after registration, which acquired a virtual nonadaptive radiotherapy plan (VPlan) and an adaptive plan (APlan). VPlan was the direct calculation of Plan0 on the fractional image, while APlan required adaptive optimization and calculation. In vivo dose monitoring and three-dimensional dose reconstruction were required during the implementation of APlan. RESULTS The inter-fractional volumes of the bladder and rectum changed greatly among the treatments. These changes influenced the primary gross tumor volume (GTVp) and the position deviation of GTVp and PTV and positively affected the prescription dose coverage of TV. GTVp decreased gradually along with dose accumulation. The Dmax, D98, D95, D50, and D2 of APlan were superior to those of VPlan in target dose distribution. APlan had good conformal index, homogeneity index and target coverage. The rectum V40 and Dmax, bladder V40, the small bowel V40 and Dmax of APlan were better than that of VPlan. The APlan's fractional mean γ passing rate was significantly higher than the international standard and the mean γ passing rate of all cases after the three-dimensional reconstruction was higher than 97.0%. CONCLUSION Online ART in external radiotherapy of UCC significantly improved the dose distribution and can become an ideal technology to achieve individualized precise radiotherapy.

Abstract
AIM This study aimed to compare the survival and toxicity of patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB1-IIIC cervical cancer without common iliac node metastasis treated with extended-field intensity-modulated radiotherapy (EF-IMRT) or pelvic IMRT (P-IMRT). MATERIALS AND METHODS Thirty-one patients treated with EF-IMRT and 37 patients who underwent P-IMRT were analysed retrospectively. Both groups were treated with high-dose-rate 192Ir two-dimensional brachytherapy and concurrent chemotherapy. The chi-square test and Kaplan-Meier method were used to compare toxicity and survival between the two groups. RESULTS The median follow-up time of EF-IMRT group and P-IMRT group was 22 and 30 months, respectively. The 3-year overall survival (OS), progression-free survival (PFS), and para-aortic lymph node metastasis-free survival (PAMFS) in the EF-IMRT group and P-IMRT group were 87% versus 74.6%, 83.6% versus 61.7%, and 96% versus 80.5%, respectively. Treatment regimens, tumour size, and radiation time were independent prognostic factors of OS and PFS. Treatment regimens, tumour size, and total equivalent dose in 2 Gy/f (EQD2) of point A were independent prognostic factors of PAMFS. Five patients in the EF-IMRT group and 14 patients in P-IMET group experienced treatment failure. The cumulative incidence of grade 3 and 4 acute leukopenia in the EF-IMRT group was 51.6%, in comparison with 27.03% in the pelvic group. No difference was found in thrombocytopenia between two groups. CONCLUSIONS Patients with FIGO 2009 stage IB1-IIIC cervical cancer without common iliac node metastases may be benefit from EF-IMRT. Notably, EF-IMRT exhibits increased toxicity incidence; however, this remains within an acceptable range.

Abstract
Concomitant chemoradiotherapy is the standard treatment for locally advanced cervical cancer. Pelvic irradiation is commonly recommended for patients with negative para-aortic lymph nodes(PALNs). However, owing to the development of imaging-guided brachytherapy, distant failure has become the main failure pattern. The PALNs are a vital site of distant metastasis, and the para-aortic region may contain occult microscopic metastases that are barely detected owing to imaging technology restriction. The prognostic of patients who experienced PALN failure is dismal. Typically, there are four ways to decrease PALN failure. First, surgical staging can be performed to assess the occurrence of metastasis in the para-aortic region; however, the application of surgical staging is decreasing owing to controversial survival benefits and accompanying complications of surgery. Second, regular imaging surveillance and timely salvage of early recurrences could reduce PALN failure. Third, better systemic adjuvant therapy could be recommended since it has enormous potential to reduce distant metastases and improve overall survival. Fourth, performing prophylactic extended-field irradiation (EFI), including pelvic and para-aortic region irradiation, can sterilize occult microscopic metastases in the para-aortic region and improve survival. Prior investigations have revealed that prophylactic EFI could reduce PALN failure as well as distant metastasis and present the benefit of survival. Yet, owing to the serious morbidity induced by enlarged irradiation field in the era of conventional irradiation techniques, further research on EFI is stagnated. Nowadays, with the development of new technologies, intensity modulated radiation therapy can deliver a higher dose to tumors with acceptable toxicity. Prophylactic EFI regained attention. However, the inclusion criteria of prophylactic EFI in existing studies reveal great discrepancies. Thus, it is urgent to precisely identify indications for better survival and lower complications in patients with cervical cancer. In this review, we identify indications and summary guidelines for prophylactic EFI, which may provide a foundation for further trials and clinical applications.

Abstract
Background Patients with locally advanced cervical cancer without para-aortic lymph node metastases (PAO-LNM) at diagnosis who undergo concurrent chemoradiotherapy are at 4-11% risk of developing PAO-LNM during follow-up. Some studies suggest a beneficial influence of elective para-aortic radiotherapy (PAO-RT) on disease-free survival (DFS) in these patients. The aim of this study was to systematically review and meta-analyse literature on the impact of PAO-RT on DFS in cervical cancer patients. Methods A systematic search of PubMed/MEDLINE and EMBASE databases was performed. The analysis included intervention studies that reported on DFS in patients with cervical cancer who received chemotherapy and pelvic radiotherapy with or without PAO-RT. From each included study, relevant study characteristics and outcome data including the hazard ratio (HR) adjusted for potential confounders were extracted. An overall pooled adjusted hazard ratio (aHR) for DFS after PAO-RT versus no PAO-RT was calculated using a random-effects model. Results A total of 2,016 articles were evaluated. Eleven articles were included in the systematic review, of which 3 were appropriate for quantitative meta-analysis. Pooling of these 3 cohorts (including 1,113 patients) demonstrated a statistically significant association between PAO-RT and DFS (pooled aHR 0.87, 95% confidence interval: 0.79-0.97). No significant heterogeneity among reported aHRs was observed (I2 = 0.0%). Conclusions This meta-analysis suggests a modest but significant beneficial impact of elective para-aortic radiotherapy on DFS in patients with locally advanced cervical cancer who undergo concurrent chemoradiotherapy. This finding based on non-randomized studies provides an imperative for further investigation in prospective controlled trials.

[PMID: 35646645 PMCID: PMC9130963 DOI: 10.3389/fonc.2022.870670] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 03/28/2022] [Indexed: 12/24/2022] Open
Abstract
Background In 2018, a revised staging system was released for cervical cancer, which defined pelvic and paraaortic lymph node metastasis as stages IIIC1 and IIIC2, respectively. In this study, we constructed and validated nomograms to predict the 3- and 5-year survival of patients with cervical cancer based on the revised International Federation of Gynecology and Obstetrics (FIGO) staging system. Methods We retrospectively examined patients with 2009 FIGO stage IB–IVA cervical cancer who were treated at our institute between 2011 and 2015. Patients were randomized into the model development and validation cohorts (2:1). Univariate and multivariate analyses were conducted for the model development cohort to identify prognostic factors. In the multivariate analysis, nomograms were built to predict overall survival (OS) and disease-free survival (DFS) using significant variables. The nomograms were assessed based on the discrimination and calibration in both cohorts. Discrimination was assessed using the concordance index. Calibration was performed by comparing the mean nomogram estimated survival and the mean observed survival. Results We included 1,192 patients, with 795 and 397 patients in the model development and validation cohorts, respectively. In the model development cohort, the median follow-up period was 49.2 months. After multivariate analysis, age, histology, 2018 FIGO stage, and pelvic lymph node number were independent factors for OS. Histology, 2018 FIGO stage, squamous cell carcinoma antigen, and pelvic lymph node number were significant predictors of DFS. The nomograms constructed to predict OS and DFS were based on these factors. In both model cohorts, the concordance index for the nomogram-predicted OS and DFS was 0.78 and 0.75 and 0.74 and 0.67, respectively. The calibration curve revealed good agreement between the nomogram predictions and actual values. Conclusion We constructed robust nomograms to predict the OS and DFS of patients with cervical cancer undergoing treatment with concurrent chemoradiotherapy based on the 2018 FIGO staging system.

Upstaging by para-aortic lymph node dissection in patients with locally advanced cervical cancer: A systematic review and meta-analysis. Gynecol Oncol 2021; 164:667-674. [PMID: 34969533 DOI: 10.1016/j.ygyno.2021.12.026] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Revised: 12/17/2021] [Accepted: 12/21/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Accurate staging of para-aortic nodal status in cervical cancer is of great importance for individualizing treatment and impacting outcomes. Three-dimensional imaging (i.e. PET, CT, MRI) may miss para-aortic lymph node (PALN) metastases. The aim of this study was to systematically review and meta-analyze the proportion of upstaging by PALN dissection in patients with locally advanced cervical cancer without suspicious PALNs on imaging. METHODS PubMed/MEDLINE and Embase were systematically searched. The analysis included diagnostic studies that reported on 3D imaging and pre-therapeutic surgical assessment of PALN status in patients with cervical cancer. An overall pooled upstaging rate was calculated using a random-effects model. RESULTS The search identified 16 eligible studies including 18 cohorts with a total of 1530 patients. Pooling of 12 cohorts demonstrated an upstaging rate of 12% (95% confidence interval [CI] 10-15%) by PALN dissection after negative PET or PET-CT. Pooling of 6 cohorts demonstrated a pooled upstaging rate of 11% (95% CI: 8-16%) by PALN dissection after negative MRI or CT. No significant heterogeneity in upstaging proportions across cohorts was observed (I2 = 0% and 27%, respectively). In 7 cohorts including only patients with pelvic nodal metastases on imaging (but no suspicion of PALN involvement) a pooled upstaging rate by PALN dissection of 21% (95% CI: 17-26%) was found (I2 = 0%). CONCLUSIONS This meta-analysis demonstrates that in case of no suspicious PALN on PET-CT or MRI, PALN dissection still identifies lymph node metastases in a considerable amount of patients with locally advanced cervical cancer and especially in those patients with confirmed pelvic nodal metastases.

Abstract
OBJECTIVE To assess risk factors for nodal failure (NF) after definitive (chemo)radiotherapy and image-guided brachytherapy for locally advanced cervical cancer (LACC) for patients treated in the EMBRACE I study. MATERIALS AND METHODS Data for pelvic NF and para-aortic (PAO) NF (NFPAO) were analysed. After multiple imputation, univariable and multivariable Cox-regression was performed for clinical and treatment-related variables. For patients with affected pelvic nodes but no PAO nodes at diagnosis, additional analyses were performed for two subgroups: 1. 'small pelvis' nodes in internal and external iliac, obturator, parametrial, presacral and/or common iliac (CI) region and 2. any CI nodes (subgroup of 1). RESULTS 1338 patients with 152 NF and 104 NFPAO events were analysed with a median follow-up of 34.2 months (IQR 16.4-52.7). For the entire group, larger tumour width, nodal risk groups (in particular any CI nodes without PAO nodes), local failure, and lower Hb-nadir increased the risk of NF. Elective PAO-irradiation was independently associated with a decreased risk of NFPAO (HR 0.53, 95%-CI 0.28-1.00, p = 0.05). For subgroup 1, having 'any CI nodes without PAO nodes' and local failure significantly increased NF risk. Additionally, elective PAO-irradiation was associated with less risk of NFPAO (HR 0.38, 95%-CI 0.17-0.86, p = 0.02). For subgroup 2 only local failure was associated with higher risk of NF. CONCLUSION In this patient cohort, nodal disease and tumour width at diagnosis, as well as local failure, are risk factors for NF after definitive treatment. Having either 'any PAO nodes' (with or without pelvic nodes) or 'any CI nodes' (without PAO nodes) are stronger risk factors than involvement of nodes in the small pelvis alone. Elective PAO-irradiation was associated with significantly less NFPAO, particularly in patients with nodal disease in the 'small pelvis' and/or CI region at time of diagnosis.

Abstract
PURPOSE To compare the volumes of interest and doses to the organs at risk on contrast and noncontrast scans in patients with cervical cancer who underwent prophylactic extended-field radiation therapy (EFRT). METHODS AND MATERIALS We reviewed twenty cervical cancer patients treated with prophylactic EFRT at Peking Union Medical College Hospital between March 2021 and April 2021. Each patient underwent noncontrast and contrast scans during simulation. All structures were contoured, and radiation therapy plans were created based on both scans. Student t test and Pearson correlation coefficient test were performed. RESULTS Compared with the noncontrast scan, on the contrast scan, the mean volume of the inferior vena cava expanded by 44% (P ≤ .001), and the mean volume of the para-aortic nodal clinical target volume increased by 17% (P ≤ .001). For the second portion of the duodenum, the V30 (38.2% vs 43.8%, P = .038), V35 (27.6% vs 35.1%, P = .002), V40 (18.3% vs 26.3%, P = .014), V45 (11.2% vs 18.5%, P = .008), and V50 (4.2% vs 9.1%, P = .005) were significantly lower on the noncontrast scan than on the contrast scan. For the third portion of the duodenum, the V45 (78.4% vs 81.6%, P = .03) and V50 (59.7% vs 67%, P ≤ .001) were significantly lower on the noncontrast scan than on the contrast scan. For the right kidney, the V5, V10, V15, V20, and V25 on the contrast and noncontrast scans were 85.4% versus 79.8% (P = .013), 52.5% versus 45.6% (P = .021), 25.6% versus 20.1% (P = .003), 11.1% versus 7.5% (P = .001), and 3.8% versus 2.3% (P = .027), respectively. CONCLUSIONS Compared with the noncontrast scan, expansion of the inferior vena cava on the contrast scan can lead to excessive contouring and an overdose to the duodenum and right kidney in cervical cancer patients treated with prophylactic EFRT.

Abstract
Background Cervical cancer is a public health problem in Latin America. Radiotherapy plays a fundamental role both as definitive or adjuvant treatment. There are important intra and inter-country differences regarding access and availability of radiotherapy facilities in this region. The aim of a study was to standardize the basic clinical and technical criteria for the radiation treatment of patients with CC in Chile and provide a guide for Latin American Radiation Oncologists. Materials and methods Forty-one expert radiation oncologists from the Chilean Radiation Oncology Society made a consensus using the Delphi methodology. Results There was a high degree of agreement for each of the recommendations. Those with the lowest percentage were related to the definition of the conformal 3D technique as the standard for definitive external radiotherapy (81%) and the criteria for extended nodal irradiation (85%). Conclusions These recommendations present an updated guide for radiotherapy treatment of patients with cervical cancer for Latin America. Those should be implemented according to local resources of each institution.

Abstract
Objective The Korean Radiation Oncology Group conducted a nationwide questionnaire survey to evaluate the patterns of clinical practice for patients with cervical cancer receiving definitive radiation therapy (RT) in South Korea. Methods Practicing radiation oncologists from 93 centers in South Korea were administered a questionnaire survey via e-mail. The survey focused on demographic characteristics, diagnostic evaluation, indications for definitive RT, RT techniques, RT field and dose prescription, lymph node (LN) boost RT, brachytherapy, and chemotherapy. Results The response rate was 62.4% (58/93 institutions). Of the 2,134 patients treated at the radiation oncology department in 2019, 48.8% underwent definitive RT. The selection of patients for definitive concurrent chemoradiation therapy and RT field, and RT dose prescription varied greatly. The upper border of the pelvis was commonly used as the bony landmark for external beam RT (81%–88% of respondents). Most (96.6%) centers performed LN boost RT with median total doses of 59 Gy and 59.2 Gy for pelvic and retroperitoneal LN, respectively. With 50% of the centers offering brachytherapy, image-guided brachytherapy and volume-based prescription were applied in 48.3% and 37.9%, respectively. Upfront concurrent chemoradiation therapy with varying prescription doses was considered by 60.4% respondents in cases of supraclavicular LN metastasis. Conclusion Most differences were noted in the indications for treatment, RT field, and prescription dose. This finding can serve as a reference for establishing practical RT guidelines for the management of locally advanced cervical cancer.

Abstract
PURPOSE To compare the survival outcome of neoadjuvant therapy (NAT) (chemotherapy or chemotherapy and intracavitary brachytherapy (ICBT) followed by radical surgery and of concomitant chemotherapy and radiotherapy (CCRT) in patients with locally advanced cervical adenocarcinoma and identify predictors of cervical adenocarcinoma. METHODS We retrospectively reviewed our medical records of cervical adenocarcinoma patients treated with either NAT + surgery or CCRT in our institution from January 2013 to December 2017. The patients were treated with two-dimensional radiotherapy or three-dimensional-conformal or intensity-modulated radiotherapy combined with intracavitary brachytherapy. The regimen of concomitant chemotherapy was weekly cisplatin. The neoadjuvant chemotherapy (NACT) was paclitaxel plus cisplatin. The primary end points were overall survival (OS) and progression-free survival (PFS). RESULTS We enrolled 121 patients. There were 42 (34.7%) patients in the NAT + surgery group and 79 (65.3%) in the CCRT group. After univariate multivariate analysis, NAT was an independent predictor of OS (p = 0.008) and PFS (p = 0.006). After propensity score matching, the 5-year OS rates in the NAT + surgery and CCRT groups were 25% and 4%, respectively (p = 0.00014), and the 5-year PFS rates were 25% and 4%, respectively (p = 0.00015). Subgroup analysis showed that the 5-year OS and PFS rates in the NACT + surgery and CCRT groups were both 20% and 8%, respectively (p = 0.015). CONCLUSION Compared with CCRT, NAT followed by radical surgery had better OS and PFS in locally advanced cervical adenocarcinoma. In subgroup analysis, OS and PFS were longer for NACT + surgery than for CCRT.

Abstract
Currently, the standard radiation field for locally advanced cervical cancer patients without evidence of para-aortic lymph node (PALN) metastasis is the pelvis. Due to the low accuracy of imaging in the diagnosis of PALN metastasis and the high incidence of PALN failure after pelvic radiotherapy, prophylactic pelvic and para-aortic irradiation, also called extended-field irradiation (EFI), is performed for patients with cervical cancer. In the era of concurrent chemoradiotherapy, randomized controlled trials are limited, and whether patients with cervical cancer can benefit from prophylactic EFI is still controversial. With conformal or intensity-modulated radiation therapy, patients tolerate prophylactic EFI very well. The severe toxicities of prophylactic EFI are not significantly higher than those of pelvic radiotherapy. We recommend delivering prophylactic EFI to cervical cancer patients with common iliac lymph nodes metastasis. Clinical trials are needed to investigate whether patients with ≥3 positive pelvic lymph nodes and FIGO stage IIIB disease can benefit from prophylactic EFI. According to the distribution of PALNs, it is reasonable to use the renal vein as the upper border of the radiation therapy field for patients treated with prophylactic EFI. The clinical target volume expansion of the node from the vessel should be smaller in the right para-caval region than in the left lateral para-aortic region. The right para-caval region above L2 or L3 may be omitted from the PALN target volume to reduce the dose to the duodenum. More clinical trials on prophylactic EFI in cervical cancer are needed.

Abstract
Objective: Previous studies have shown that prophylactic extended-field irradiation can reduce para-aortic lymph node failure (PALNF) rates in patients with cervical cancer. As such, this type of irradiation may particularly benefit patients with a high risk of PALNF. In the present study, we analyzed the risk factors for PALNF in patients with cervical cancer treated with pelvic irradiation in order to identify potential indications of prophylactic extended-field irradiation. Methods: We evaluated patients with 2018 FIGO stage IB3-IIIC1 cervical cancer who were treated with definitive pelvic radiotherapy or concurrent chemoradiotherapy at our institution between 2011 and 2014. Univariate and multivariate analyses were performed to identify risk factors for PALNF. Results: We included 572 patients in the study. The median follow-up period was 37.9 months. Eighteen patients (3.1%) first site of tumor relapse was the para-aortic lymph nodes, and thus showed PALNF. Using multivariate Cox regression analysis, we identified two significant risk factors for PALNF: tumor extension to the pelvic wall (hazard ratio, HR 3.60, p=0.026) and ≥ 2 pelvic MLNs (HR 5.30, p=0.005). For patients with and without risk factors, the 3-year overall survival, disease-free survival, and PALNF rates were 77.3% and 90.1% (p<0.001), 56.4% and 83.1% (p<0.001), and 12.0% and 2.3% (p<0.001), respectively. Conclusion: Tumor extension to the pelvic wall and ≥ 2 pelvic MLNs are positively associated with PALNF after pelvic irradiation in patients with cervical cancer. Further trials will be required to validate whether patients with these two risk factors may benefit from prophylactic extended-field irradiation.

A Risk Stratification for Patients with Cervical Cancer in Stage IIIC1 of the 2018 FIGO Staging System. Sci Rep 2020; 10:362. [PMID: 31941966 PMCID: PMC6962323 DOI: 10.1038/s41598-019-57202-3] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Accepted: 12/21/2019] [Indexed: 12/29/2022] Open
Abstract
This retrospective study was designed to investigate the heterogeneity of patients with cervical cancer in stage IIIC1 (the 2018 International Federation of Gynecology and Obstetrics staging system, FIGO) and conduct a risk stratification for this group of patients. We reviewed clinical records of 325 patients with stage IIIC1 treated with definitive concurrent chemoradiotherapy in our institute between January 2008 and December 2014. The median follow-up duration was 28.4 months (range: 1.9–114.2 months). The 3-year DFS for the 325 eligible patients was 66.3%. Tumor size of ≥4 cm and number of pelvic lymph node metastasis ≥2 were identified as adverse prognostic factors for disease free survival (DFS) in cervical cancer patients with stage IIIC1 (2018). A risk stratification based on the number of identified prognostic factors for DFS was performed. The 3-year DFS for patients in low-risk (without prognostic factor), intermediate-risk (with one prognostic factor) and high-risk group (with two prognostic factors) was 92.1%, 70.0%, and 51.1%, respectively (P < 0.001). Our study confirms the heterogeneity of patients with cervical cancer in FIGO stage IIIC1 (the 2018 FIGO staging system). Tumor size and number of pelvic lymph node metastasis (PLNM) are significant prognostic factors for DFS in patients with FIGO stage IIIC1. The next revision of FIGO staging system for cervical cancer, especially for stage IIIC1, should focus on tumor size and number of pelvic lymph node metastasis.

Evaluation of the efficacy of prophylactic extended field irradiation in the concomitant chemoradiotherapy treatment of locally advanced cervical cancer, stage IIIB in the 2018 FIGO classification. Radiat Oncol 2019; 14:228. [PMID: 31842919 PMCID: PMC6915883 DOI: 10.1186/s13014-019-1431-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 11/26/2019] [Indexed: 11/10/2022] Open
Abstract
Background The new staging system of cervical cancer issued in 2018 by the International Federation of Gynecology and Obstetrics (FIGO), calls for a new evaluation of the efficacy of prophylactic extended field irradiation (EFI) in the concomitant chemoradiotherapy/brachytherapy treatment of locally advanced cervical cancer patients (stage IIIB). Methods We performed a retrospective study consisting of 133 FIGO IIIB cervical cancer patients treated in the Peking Union Medical College Hospital from 2002 to 2010. The patients were distributed in two groups depending whether they were treated with EFI or pelvic only irradiation. The therapeutic efficacy, toxicity and prognostic factors of EFI were evaluated in the frame of the new FIGO staging system. Results When compared to patients who received pelvic only irradiation, patients who received prophylactic EFI showed significantly less distant metastasis and a significant improvement in their 5 years overall survival (OS), disease free survival (DFS), out of field recurrence free survival (OFRFS) and para-aortic lymph node metastasis free survival (PALNMFS). Multivariate analysis revealed that EFI is an independent prognosis factor for DFS, OFRFS and PALNMFS. Finally, although more acute complications were observed in the EFI group, there is no significantly worst acute toxicity in the EFI group. Conclusion Our retrospective analysis supports the prophylactic effect of EFI in the concomitant chemoradiotherapy treatment of IIIB patients and suggests that this prophylactic effect is associated with a clear improvement in 5-years OS, DFS, OFRFS and PALNMFS. Consequently, EFI appears to be a very valid treatment option for FIGO IIIB cervical cancer patients.

Reduction of dose to duodenum with a refined delineation method of Para-aortic region in patients with locally advanced cervical Cancer receiving prophylactic extended-field radiotherapy. Radiat Oncol 2019; 14:196. [PMID: 31703705 PMCID: PMC6839216 DOI: 10.1186/s13014-019-1398-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Accepted: 10/16/2019] [Indexed: 12/03/2022] Open
Abstract
Background To compare irradiation dose to the second and third portions of duodenum (Duo2 and Duo3) with a new refined and old delineation method of para-aortic region for patients with locally advanced cervical cancer (LACC) receiving prophylactic extended-field radiotherapy (EFRT). Methods Twenty consecutive patients with LACC were treated with prophylactic EFRT from January 2016 to January 2017 at our institute. Two delineation methods of para-aortic region were designed for each patient, the old delineation method ensured a full coverage of aortic and inferior vena cava, while the right paracaval region above L3 was omitted from CTV in the new delineation method. Patients received a dose of 50.4Gy in 28 fractions for PCTV and a dose of 60.2Gy in 28 fractions for PGTV with volumetric-modulated arc therapy (VMRT). The dose delivered to Duo2 and Duo3 with these two delineation methods were compared. Results All treatment plans achieved excellent target volume coverage with 95% of PCTV receiving 50.4Gy and 95% of PGTV receiving 60.2Gy. There was no difference between delineation methods in low dose level (V5, V10, V15, V20, V25) for Duo2 and Duo3. The V30, V35, V40, V45, V50, Dmax, Dmean and D2cc for Duo2 with the new and old delineation methods were 55.76% vs 80.54% (P = 0.009), 34.72% vs 70.91% (P < 0.001), 18.69% vs 55.46% (P < 0.001), 8.20% vs 41.49% (P < 0.001), 1.86% vs 21.60% (P < 0.001), 49.58Gy vs 52.91Gy (P = 0.002), 30.38Gy vs 39.22Gy (P = 0.001) and 37.90Gy vs 48.64Gy (P < 0.001) respectively. For Duo3, the new delineation method achieved significant advantages in V30, V35, V40, V45, V50 and Dmean over the old one (96.82% vs 99.25%, P = 0.021; 89.65% vs 97.21%, P = 0.001; 79.50% vs 93.18%, P < 0.001; 65.63% vs 82.93%, P < 0.001; 43.39% vs 65.60%, P < 0.001; 46.09Gy vs 49.24Gy, P < 0.001), no deference was observed regarding D2cc and Dmax with these two delineation methods. Conclusion With the new delineation method of para-aortic area in prophylactic EFRT, significant reduction of irradiation dose to the second and third portions of duodenum in high dose area was obtained. This may further lower the incidence of duodenal toxicity when performing prophylactic EFRT for patients with LACC.

Abstract
This Systematic Review summarizes the literatures of clinical trials on the efficacy and safety of carbon ion therapy for gynecological carcinomas. The protocol is detailed in the online PROSPERO database, registration no. CRD42019121424, and a final set of eight studies were included. In the treatment of cervical carcinomas, both carbon ion therapy alone and carbon ion therapy concurrent chemotherapy have presented good efficacy. Besides, the efficacy of inoperable endometrial carcinomas and gynecological melanoma are similar to that of surgical treatment. In terms of safety, gastrointestinal and genitourinary toxicities are low and could be controlled by limiting the volume and dose of intestinal tract and bladder. Carbon ion radiotherapy could be considered a safe, effective and feasible therapy for gynecological carcinomas.

The role of squamous cell carcinoma antigen (SCC Ag) in outcome prediction after concurrent chemoradiotherapy and treatment decisions for patients with cervical cancer. Radiat Oncol 2019; 14:146. [PMID: 31416463 PMCID: PMC6694518 DOI: 10.1186/s13014-019-1355-4] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Accepted: 08/06/2019] [Indexed: 11/10/2022] Open
Abstract
At present, the standard treatment approach for locally advanced cervical cancer is concurrent chemoradiotherapy (CCRT). An elevated pretreatment squamous cell carcinoma antigen (SCC Ag) level is associated with extensive tumors and poor survival for patients with cervical cancer treated with definitive CCRT. SCC Ag levels can be used to help physicians make decisions regarding surgery, avoiding the complications of double treatment modalities. Elevated SCC Ag is associated with radiotherapy resistance, and the rate of SCC Ag reduction during CCRT can predict tumor response after treatment. Moreover, the failure of SCC Ag levels to normalize posttreatment can predict tumor relapse, with a specificity higher than 70%, and adjuvant therapies should be considered for these patients. SCC Ag also plays an important role in the early detection of tumor relapse in patients with cervical cancer during follow-up after CCRT, with high sensitivity and good cost-effectiveness.

Abstract
Background Concurrent chemoradiotherapy (CCRT) is effective in the treatment of locally advanced cervical squamous cell carcinoma (SCC). However, whether treatment outcomes of cervical adenocarcinoma are equivalent to SCC after CCRT has been a topic of debate. Methods Medical records of cervical cancer patients treated with definitive radiotherapy or CCRT in our institute from January 2011 to December 2014 were reviewed. Patients were treated with intensity modulated radiation therapy combined with intracavitary brachytherapy. Weekly cisplatin was the first line regimen of concurrent chemotherapy. The treatment outcomes of patients with SCC and adenocarcinoma were compared with a multivariate Cox regression model, and log-rank method before and after propensity score matching (1:1). Results A total of 815 patients with stage IB-IVA cervical cancer were included, with 744 patients in the SCC group and 71 patients in adenocarcinoma group. The median follow-up period was 36.2 months (range, 1.0–76.2 months). The 3-year overall survival (OS), disease-free survival (DFS), pelvic control and distant control rates of patients in the SCC group and adenocarcinoma group were 85.2 and 75.4% (p = 0.005), 77.5 and 57.3% (p < 0.001), 89.0 and 74.0% (p = 0.001) and 86.0 and 74.4% (p = 0.011), respectively. After multivariate analysis, histology was an independent factor of OS (p = 0.003), DFS (p < 0.001), pelvic control (p = 0.002) and distant control (p = 0.003). With propensity score matching, 71 pairs of patients were selected. After matching, the OS (p = 0.017), DFS (p = 0.001), pelvic control (p = 0.015) and distant control (p = 0.009) of patients with adenocarcinoma were poorer than those of patients with SCC. In subgroup analysis, patients with adenocarcinoma had significantly worse OS and DFS compared with patients with SCC, regardless of treatment with radiotherapy alone or CCRT. Conclusion The present study demonstrated that patients with adenocarcinoma of the cervix had poorer OS and DFS than patients with SCC, regardless of treatment with radiotherapy alone or CCRT. New treatment approaches should be considered for cervical adenocarcinoma.
