Abstract
Gynecologic malignancies, consisting of endometrial, cervical, ovarian, vulvar, and vaginal cancers, pose significant diagnostic and management challenges due to their complex anatomic location and potential for rapid progression. These tumors cause substantial morbidity and mortality, often because of their delayed diagnosis and treatment. An estimated 19% of newly diagnosed cancers among women are gynecologic in origin. In recent years, there has been growing evidence supporting the integration of nuclear medicine imaging modalities in the diagnostic work-up and management of gynecologic cancers. The sensitivity of fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) combined with the anatomical specificity of computed tomography (CT) and magnetic resonance imaging (MRI) allows for the hybrid evaluation of metabolic activity and structural abnormalities that has become an indispensable tool in oncologic imaging. Lymphoscintigraphy, using technetium 99m (99mTc) based radiotracers along with single photon emission computed tomography/ computed tomography (SPECT/CT), holds a vital role in the identification of sentinel lymph nodes to minimize the surgical morbidity from extensive lymph node dissections. While not yet standard for gynecologic malignancies, promising therapeutic nuclear medicine agents serve as specialized treatment options for patients with advanced or recurrent disease. This article aims to provide a comprehensive review on the nuclear medicine applications in gynecologic malignancies through the following objectives: 1) To describe the role of nuclear medicine in the initial staging, lymph node mapping, response assessment, and recurrence/surveillance imaging of common gynecologic cancers, 2) To review the limitations of 18F-FDG PET/CT and promising applications of 18F-FDG PET/MRI in gynecologic malignancy, 3) To underscore the promising theragnostic applications of nuclear medicine, 4) To highlight the current role of nuclear medicine imaging in gynecologic cancers as per the National Comprehensive Cancer Network (NCCN), European Society of Surgical Oncology (ESGO), and European Society of Medical Oncology (ESMO) guidelines.

Prediction of Patient Outcomes in Locally Advanced Cervical Carcinoma Following Chemoradiotherapy-Comparative Effectiveness of Magnetic Resonance Imaging and 2-Deoxy-2-[ 18F]fluoro-D-glucose Imaging. Cancers (Basel) 2024; 16:476. [PMID: 38339229 PMCID: PMC10854890 DOI: 10.3390/cancers16030476] [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: 12/18/2023] [Revised: 01/16/2024] [Accepted: 01/18/2024] [Indexed: 02/12/2024] Open
Abstract
PURPOSE To evaluate the utility and comparative effectiveness of three five-point qualitative scoring systems for assessing response on PET-CT and MRI imaging individually and in combination, following curative-intent chemoradiotherapy (CRT) in locally advanced cervical cancer (LACC). Their performance in the prediction of subsequent patient outcomes was also assessed; Methods: Ninety-seven patients with histologically confirmed LACC treated with CRT using standard institutional protocols at a single centre who underwent PET-CT and MRI at staging and post treatment were identified retrospectively from an institutional database. The post-CRT imaging studies were independently reviewed, and response assessed using five-point scoring tools for T2WI, DWI, and FDG PET-CT. Patient characteristics, staging, treatment, and follow-up details including progression-free survival (PFS) and overall survival (OS) outcomes were collected. To compare diagnostic performance metrics, a two-proportion z-test was employed. A Kaplan-Meier analysis (Mantel-Cox log-rank) was performed. RESULTS The T2WI (p < 0.00001, p < 0.00001) and DWI response scores (p < 0.00001, p = 0.0002) had higher specificity and accuracy than the PET-CT. The T2WI score had the highest positive predictive value (PPV), while the negative predictive value (NPV) was consistent across modalities. The combined MR scores maintained high NPV, PPV, specificity, and sensitivity, and the PET/MR consensus scores showed superior diagnostic accuracy and specificity compared to the PET-CT score alone (p = 0.02926, p = 0.0083). The Kaplan-Meier analysis revealed significant differences in the PFS based on the T2WI (p < 0.001), DWI (p < 0.001), combined MR (p = 0.003), and PET-CT/MR consensus scores (p < 0.001) and in the OS for the T2WI (p < 0.001), DWI (p < 0.001), and combined MR scores (p = 0.031) between responders and non-responders. CONCLUSION Post-CRT response assessment using qualitative MR scoring and/or consensus PET-CT and MRI scoring was a better predictor of outcome compared to PET-CT assessment alone. This requires validation in a larger prospective study but offers the potential to help stratify patient follow-up in the future.

Abstract
OBJECTIVE Positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro- D-glucose integrated with computed tomography (18F-FDG PET/CT) or magnetic resonance imaging (18F-FDG PET/MRI) has emerged as a promising tool for managing various types of cancer. This review study was conducted to investigate the role of 18F- FDG PET/CT and FDG PET/MRI in the management of gynecological malignancies. SEARCH STRATEGY We searched for relevant articles in the three databases PubMed/MEDLINE, Scopus, and Web of Science. SELECTION CRITERIA All studies reporting data on the FDG PET/CT and FDG PET MRI in the management of gynecological cancer, performed anywhere in the world and published exclusively in the English language, were included in the present study. DATA COLLECTION AND ANALYSIS We used the EndNote software (EndNote X8.1, Thomson Reuters) to list the studies and screen them on the basis of the inclusion criteria. Data, including first author, publication year, sample size, clinical application, imaging type, and main result, were extracted and tabulated in Excel. The sensitivity, specificity, and diagnostic accuracy of the modalities were extracted and summarized. MAIN RESULTS After screening 988 records, 166 studies published between 2004 and 2022 were included, covering various methodologies. Studies were divided into the following five categories: the role of FDG PET/CT and FDG-PET/MRI in the management of: (a) endometrial cancer (n = 30); (b) ovarian cancer (n = 60); (c) cervical cancer (n = 50); (d) vulvar and vagina cancers (n = 12); and (e) gynecological cancers (n = 14). CONCLUSIONS FDG PET/CT and FDG PET/MRI have demonstrated potential as non-invasive imaging tools for enhancing the management of gynecological malignancies. Nevertheless, certain associated challenges warrant attention.

FDG PET-CT as an important diagnostic tool and prognostic marker in suspected recurrent cervical carcinoma after radiotherapy: comparison with MRI. Radiol Oncol 2022; 56:453-460. [PMID: 36317553 PMCID: PMC9784362 DOI: 10.2478/raon-2022-0042] [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: 04/18/2022] [Accepted: 09/15/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Recurrent disease in post-irradiation patients with cervical cancer is often difficult to delineate on magnetic resonance imaging (MRI), because posttreatment changes can have a similar appearance, and further evaluation is often required. The aims of the study were to evaluate positron emission tomography/computed tomography with 18F-fluorodeoxyglucose (FDG PET-CT) diagnostic role in suspected recurrent cervical cancer after radiotherapy, compare it to MRI, and assess their prognostic impact in these patients. PATIENTS AND METHODS This cohort retrospective study included patients previously treated with radiotherapy for carcinoma of uterine cervix with suspected recurrence, who had undergone MRI of abdomen and pelvis, and were subsequently evaluated on FDG PET-CT, with minimum follow-up period of 12 months. RESULTS In the total of 84 patients included in analysis, MRI vs. FDG PET-CT showed sensitivity, specificity and accuracy of 80.1%, 52.4% and 66.7%, vs. 97.6%, 61.9% and 79.8%, respectively. Patients with positive findings on MRI (Log Rank, p = 0.003) and PET-CT (Log Rank, p < 0.001) had shorter progression-free survival (PFS) than those with negative results. In univariate Cox regression models, MRI and FDG PET-CT results were found to be related to PFS (p = 0.005 and p < 0.001, respectively). However, multivariate analysis proved only FDG PET-CT to be independent prognostic factor, where patients with positive FDG PET-CT results had almost nine times higher risk of progression (p < 0.001). CONCLUSION FDG PET-CT represents useful diagnostic tool in suspected recurrent cervical cancer after radiotherapy, showing high sensitivity in its detection. In addition, it is an independent factor in predicting progression-free survival in these patients.

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.

Prognostic values of ADC mean and SUV max of the primary tumour in cervical cancer patients treated with definitive chemoradiotherapy. J OBSTET GYNAECOL 2018; 39:224-230.

Abstract
We analysed the correlation of 18F-fluorodeoxyglucose uptake into primary tumours using the maximum standardised uptake value (SUVmax) and the mean apparent diffusion coefficient (ADCmean) values in magnetic resonance imaging (MRI) with the clinical and pathological factors in patients with cervical cancer who were treated with concurrent chemoradiotherapy. The patients were stratified according to the primary tumour pre-treatment ADCmean and SUVmax cut-off values. There were significant correlations between the SUVmax of the primary tumour and tumour size, and the treatment response. The correlation between the ADCmean and FIGO stage, tumour size, and the lymph node metastasis was significant. The SUVmax was significantly and inversely correlated with the ADCmean for cervical cancer (r = -0.44, p <.001). In the multivariate analysis, the primary tumour ADCmean, treatment response and the lymph node metastasis emerged as significant independent predictors of both OS and DFS, and of the primary tumour SUVmax for DFS. Tumour size has a borderline significance for OS. High SUVmax and low ADCmean of the primary tumour are important predictive factors for identifying high-risk patients with cervical cancer who are treated with definitive chemoradiotherapy. These results point to a future role for the diffusion-weighted MRI and for 18F-fluorodeoxyglucose positron emission tomography, not only in the staging of cervical cancer but as an aid in the selection of an adjuvant treatment regimen after chemoradiotherapy for individual patients. Impact statement What is already known on this subject? A negative correlation between primary tumour SUVmax derived from positron emission tomography (PET/CT) and ADCmin derived from diffusion weighted magnetic resonance imaging (DW-MRI) in various cancer types and cervical cancer has been demonstrated. However, the prognostic value of primary tumour SUVmax and ADCmean in cervical cancer patients treated with definitive chemoradiotherapy is not well studied yet. What the results of this study add? The patients with high-risk features (larger tumours, extensive stage, lymph node metastasis) had higher primary tumour SUVmax and lower ADCmean values. Primary tumour ADCmean and lymph node metastasis emerged as significant independent predictors of both overall and disease-free survival. This study demonstrated that the functional biomarkers delivered from PET-CT and DW-MRI are important in predicting the treatment outcomes in the squamous cell carcinoma of cervix treated with definitive chemoradiotherapy, where clinical and radiological findings are very important, since these patients are not staged surgically. What are the implications of these findings for clinical practice and/or further research? Based on these findings, there may be a future role of DW-MRI and FDG/PET-CT not only in the staging of cervical cancer but as an aid in the selection of an adjuvant treatment regimen after chemoradiotherapy (ChRT) for individual patients.

Clinical Value of Combining 18F-FDG PET/CT and Routine Serum Tumor Markers in The Early Detection of Recurrence Among Follow-up Patients Treated for Cervical Squamous Cell Carcinoma. J Cancer 2018; 9:3101-3108. [PMID: 30210633 PMCID: PMC6134808 DOI: 10.7150/jca.27206] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Accepted: 06/28/2018] [Indexed: 01/27/2023] Open
Abstract
Objective: The purpose of this retrospective study was to investigate the role of 18F-Fluorodeoxyglucose Positron Emission Tomography (18F-FDG PET/CT) and evaluate if combined elevated serum tumor markers levels improve the accuracy of 18F-FDG PET/CT in detecting recurrence of cervical squamous cell carcinoma. Methods: A total number of 42 patients who were treated for cervical squamous cell carcinoma and had underwent 18F-FDG PET/CT for suspected recurrence of cervical cancer were retrospectively reviewed in this study and their clinical, pathological and serological data were collected and analyzed. The clinical value of combining 18F-FDG PET/CT with serum tumor markers was investigated. Results: Among the 42 patients, 18F-FDG PET/CT was true positive in 25 (59.5%), false positive in 5 (11.9%), true negative in 12 (28.5%) and false negative in none. The overall patient-based sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 18F-FDG PET/CT in detecting recurrent cervical cancer were 100%, 70.6, 88.1%, 83.3%, and 100%, respectively. The accuracy of 18F-FDG PET/CT with combined squamous cell carcinoma antigen (SCC Ag) and carcinoembryonic antigen (CEA) elevation was 100% compared to only SCC Ag elevation and only CEA elevation, 90% and 33.3%, respectively. The positive predictive value of a positive 18F-FDG PET/CT with combined SCC Ag and CEA elevation was 100% for detection of recurrent cervical cancer. Also, the negative predictive value of a negative 18F-FDG PET/CT combined with normal SCC Ag and CEA levels was 100%. Conclusion:18F-FDG PET/CT is highly sensitive in the diagnosis of recurrent cervical cancer. When 18F-FDG PET/CT is associated with both SCC Ag and CEA elevation or only SCC Ag elevation, the accuracy is increased but not when associated with only CEA elevation. Positive 18F-FDG PET/CT associated with both tumor markers elevation can precisely predict recurrence. Moreover, normal levels of both tumor markers with a negative 18F-FDG PET/CT result may clinically reassure that a recurrence is absent.

Objectives To evaluate the utility of a standardized qualitative scoring system for treatment response assessment at 18F-FDG PET-CT in patients undergoing chemoradiotherapy for locally advanced cervical carcinoma and correlate this with subsequent patient outcome. Methods Ninety-six consecutive patients with locally advanced cervical carcinoma treated with radical chemoradiotherapy (CRT) in a single centre between 2011 and 2014 underwent 18F-FDG PET-CT approximately 3 months post-treatment. Tumour metabolic response was assessed qualitatively using a 5-point scale ranging from background level activity only through to progressive metabolic disease. Clinical and radiological (MRI pelvis) follow-up was performed in all patients. Progression-free (PFS) and overall survival (OS) was calculated using the Kaplan-Meier method (Mantel-Cox log-rank) and correlated with qualitative score using Chi-squared test. Results Forty patients (41.7 %) demonstrated complete metabolic response (CMR) on post-treatment PET-CT (Score 1/2) with 38 patients (95.0 %) remaining disease free after a minimum follow-up period of 18 months. Twenty-four patients (25.0 %) had indeterminate residual uptake (ID, Score 3) at primary or nodal sites after treatment, of these eight patients (33.3 %) relapsed on follow-up, including all patients with residual nodal uptake (n = 4Eleven11 of 17 patients (64.7 %) with significant residual uptake (partial metabolic response, PMR, Score 4) subsequently relapsed. In 15 patients (15.6 %) PET-CT demonstrated progressive disease (PD, Score 5) following treatment. Kaplan-Meier analysis showed a highly statistically significant difference in PFS and OS between patients with CMR, indeterminate uptake, PMR and PD (Log-rank, P < 0.0001). Chi-squared test demonstrated a highly statistically significant association between increasing qualitative score and risk of recurrence or death (P < 0.001). Conclusion Use of a 5-point qualitative scoring system to assess metabolic response to CRT in locally advanced cervical carcinoma predicts survival outcome and this prognostic information may help guide further patient management.

Abstract
BACKGROUND In 2009, the Program in Evidence-based Care (pebc) of Cancer Care Ontario published a guideline on the follow-up of cervical cancer. In 2014, the pebc undertook an update of the systematic review and clinical practice guideline for women in this target population. METHODS The literature from 2007 to August 2014 was searched using medline and embase [extended to 2000 for studies of human papillomavirus (hpv) dna testing]. Outcomes of interest were measures of survival, diagnostic accuracy, and quality of life. A working group evaluated the need for changes to the earlier guidelines and incorporated comments and feedback from internal and external reviewers. RESULTS One systematic review and six individual studies were included. The working group concluded that the new evidence did not warrant changes to the 2009 recommendations, although hpv dna testing was added as a potentially more sensitive method of detecting recurrence in patients treated with radiotherapy. Comments from internal and external reviewers were incorporated. RECOMMENDATIONS SUMMARY Follow-up care after primary treatment should be conducted and coordinated by a physician experienced in the surveillance of cancer patients. A reasonable follow-up strategy involves visits every 3-4 months within the first 2 years, and every 6-12 months during years 3-5. Visits should include a patient history and complete physical examination, with elicitation of relevant symptoms. Vaginal vault cytology examination should not be performed more frequently than annually. Combined positron-emission tomography and computed tomography, other imaging, and biomarker evaluation are not advocated; hpv dna testing could be useful as a method of detection of recurrence after radiotherapy. General recommendations for follow-up after 5 years are also provided.

Abstract
F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) has of late gained prominence in the investigation of cervical cancer since it gives a better clarity on imaging modalities for the status of the lymph node and distant metastasis. The current review is an appraisal of the recent updates on the role of FDG-PET/CT in the screening of cervical cancer as evidenced by publications till date. 985 studies were obtained in the initial search on cervical cancer and publications selected based on inclusion and exclusion criteria. In the final selection, 14 were selected and coded as the most appropriate for the present review. Valuable studies on (FDG) PET/CT have been identified. These studies point to the fact that recent advanced protocols like PET/CT supported by therapeutic innovations ensure better cancer care and survival chances in cervical cancer patients.

Abstract
BACKGROUND Positron emission tomography-computed tomography (PET-CT) is recommended to triage women for exenterative surgery and surveillance after treatment for advanced cervical cancer. OBJECTIVE To evaluate diagnostic accuracy of additional whole body PET-CT compared with CT/magnetic resonance imaging (MRI) alone in women with suspected recurrent/persistent cervical cancer and in asymptomatic women as surveillance. DESIGN Systematic reviews. Subjective elicitation to supplement diagnostic information. SEARCH STRATEGY/SELECTION CRITERIA/DATA COLLECTION AND ANALYSIS Searches of electronic databases were performed to June 2013. Studies in women with suspected recurrent/persistent cervical cancer and in asymptomatic women undergoing follow up with sufficient numeric data were included. We calculated sensitivity, specificity and corresponding 95% confidence intervals. Meta-analyses employed a bivariate model that included a random-effects term for between-study variations (CT studies) and univariate random effects meta-analyses (PET-CT studies) for sensitivity and specificity separately. SUBJECTIVE ELICITATION Prevalence of recurrence and the accuracy of imaging elicited using the allocation of points technique. Coherence of elicited subjective probabilities with estimates in the literature examined. RESULTS We identified 15 relevant studies; none directly compared additional PET-CT with MRI or CT separately. Most CT and MRI studies used older protocols and the majority did not distinguish between asymptomatic and symptomatic women. Meta-analysis of nine PET-CT studies in mostly symptomatic women showed sensitivity of 94.8 (95% CI 91.2-96.9), and specificity of 86.9% (95% CI 82.2-90.5). The summary estimate of the sensitivity of CT for detection of recurrence was 89.64% (95% CI 81.59-94.41) and specificity was 76% (95% CI 43.68-92.82). Meta-analysis for MRI test accuracy studies was not possible because of clinical heterogeneity. The sensitivity and specificity of MRI in pelvic recurrence varied between 82 and 100% and between 78 and 100%, respectively. Formal statistical comparisons of the accuracy of index tests were not possible. Subjective elicitation provided estimates comparable to the literature. Subjective estimates of the increase in accuracy from the addition of PET-CT were less than elicited increases required to justify the use in PET-CT for surveillance. CONCLUSION Evidence to support additional PET-CT is scarce, of average quality and does not distinguish between application for surveillance and diagnosis. Guidelines recommending PET-CT in recurrent cervical cancer need to be reconsidered in the light of the existing evidence base.

Abstract
BACKGROUND Platinum-based primary or adjuvant chemoradiation is the treatment of choice for patients with cervical cancer. However, despite national guidelines and international recommendations, many aspects in diagnosis, therapy, and follow-up of patients with cervical cancer are not based on valid data. METHODS To evaluate the current patterns of care for patients with cervical cancer in Germany, a questionnaire with 25 items was sent to 281 radiooncologic departments and out-patient health care centers. RESULTS The response rate was 51%. While 87% of institutions treat 0-25 patients/year, 12 % treat between 26 and 50 and only 1% treat more than 50 patients/year. In 2011, the stage distribution of 1,706 treated cervical cancers were IB1, IB2, IIA, IIB, IIIA/IIIB, and IV in 11, 12, 11, 22, 28, and 16%, respectively. CT (90%) and MRI (86%) are mainly used as staging procedures in contrast to PET-CT with 14%. Interestingly, 27% of institutions advocate surgical staging prior to chemoradiation. In the majority of departments 3D-based (70%) and intensity-modulated radiotherapy (76%) are used for percutaneous radiation, less frequently volumetric arc techniques (26%). Nearly all colleagues (99.3%) apply conventional fractioning of 1.8-2 Gy for external-beam radiotherapy, in 19% combined with a simultaneous integrated boost. Cisplatinum mono is used as a radiosensitizer with 40 mg/m(2) weekly by 90% of radiooncologists. For boost application in the primary treatment, HDR (high-dose rate) brachytherapy is the dominant technique (84%). In patients after radical hysterectomy pT1B1/1B2, node negative and resection in sound margins adjuvant chemoradiation is applied due to the occurrence of 1-4 other risk factors in 16-97%. There is a broad spectrum of recommended primary treatment strategies in stages IIB and IVA. CONCLUSION Results of the survey underline the leading role but also differences in the use of chemoradiation in the treatment of cervical cancer patients in Germany.

Abstract
Introduction: In spite of the existence of guidelines and international recommendations, many aspects in the diagnosis, therapy and follow-up of patients with cervical cancer are not based on validated data. A broad spectrum of different opinions and procedures concerning the therapy for patients with cervical cancer is under controversial discussion by the responsible gynaecologists in German hospitals. Methods: The present study is intended to picture the current treatment situation for cervical cancer in Germany. For this purpose a specially developed questionnaire with questions divided into 19 subsections was sent to all 688 gynaecological hospitals in Germany. Results: The response rate to the questionnaire was 34 %. 91 % of the hospitals treated between 0 and 25 patients with cervical cancer per year. 7.5 % treated between 26 and 50 and 1.4 % of the hospitals more than 50 patients per year. The bimanual examination was the most frequently used staging method (98 %); PET-CT was the least used staging method (2.3 %). Interestingly 48 % of the hospitals used surgical staging. The great majority of the hospitals (71 %) used abdominal radical hysterectomy (Wertheim-Meigs operation) to treat their patients. TMMR via laparotomy was used by 13 %. 16 % of the hospitals performed laparoscopic or robot-assisted radical hysterectomies. The sentinel concept was hardly used even in the early stages. It must be emphasised that in 74 % of the hospitals radical hysterectomies were performed even in cases with positive pelvic lymph nodes and in 43 % also in cases with positive paraaortic lymph nodes. The therapy of choice for FIGO IIB cancers is primary radiochemotherapy (RCTX) in 21 % of the hospitals; operative staging followed by radiochemotherapy in 24 % and treatment by radical hysterectomy followed by adjuvant RCTX was employed in this situation by 46 % of the hospitals. In 15-97 % of the hospitals for node-negative and in sano resected patients in stage pT1B1/1B2 after radical hysterectomy, an adjuvant RCTX is recommended when further risk factors exist (LVSI, tumour > 4 cm, age < 40 years, adenocarcinoma, S3). Conclusion: A broad spectrum of differing staging and therapy concepts is in use for patients with cervical cancer in Germany. A standardisation of therapy is needed. An update of national guidelines could help to achieve more transparency and a standardisation of treatment for patients with cervical cancer.
