Abstract
Tissue ablation techniques have emerged as a critical component of modern medical practice and biomedical research, offering versatile solutions for treating various diseases and disorders. Percutaneous ablation is minimally invasive and offers numerous advantages over traditional surgery, such as shorter recovery times, reduced hospital stays, and decreased healthcare costs. Intra-procedural imaging during ablation also allows precise visualization of the treated tissue while minimizing injury to the surrounding normal tissues, reducing the risk of complications. Here, the mechanisms of tissue ablation and innovative energy delivery systems are explored, highlighting recent advancements that have reshaped the landscape of clinical practice. Current clinical challenges related to tissue ablation are also discussed, underlining unmet clinical needs for more advanced material-based approaches to improve the delivery of energy and pharmacology-based therapeutics.

Brachytherapy 2024; 23:266-273. [PMID: 38453533 DOI: 10.1016/j.brachy.2023.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 12/08/2023] [Accepted: 12/30/2023] [Indexed: 03/09/2024]
Abstract
INTRODUCTION Treatment of recurrent oligometastatic gynecologic malignancy may involve targeted surgery, thermal ablation, or CT-guided high-dose-rate interstitial brachytherapy ablation (CT-HDR-IBTA). The purpose of this study was to describe the safety and efficacy of CT-HDR-IBTA for oligometastatic gynecologic malignancies. METHODS With institutional review board approval (IRB) approval and compliance with the Health Insurance Portability and Accountability Act of 1996 (HIPAA) compliance, we searched our database to assemble a single-arm study cohort of all patients with oligometastatic gynecologic cancers who underwent CT-HDR-IBTA from 2012-2022 with follow-up. The electronic record was reviewed to determine relevant clinicopathological variables including patient demographics, prior treatments, clinical course, local control, and local and distant recurrence with follow-up imaging. RESULTS The study cohort comprised 37 lesions in 34 patients treated with CT-HDR-IBTA for recurrent oligometastatic uterine (n = 17), cervix (n = 1), or ovarian cancer (n = 16) with an average lesion size of 2.5 cm with an average patient age of 61.4 years. Each lesion was treated with an average radiation dose of 23.8 Gy in 1.8 fractions and a median follow-up time of 24.0 months. The primary efficacy of CT HDR ITBA was 73% with a median progression-free survival of 8.0 months (95% CI 3.6-12.8 months) and with 58% of patients still alive at 43 months with median overall survival not reached. The rate of Grade 1 adverse events was 22% without any Grade 2, 3 or 4 events. CONCLUSIONS CT HDR IBTA was safe and effective for treating oligometastatic gynecologic cancers in a heavily pretreated cohort.

Abstract
Purpose Endometrial carcinoma (EC) is a common gynecological malignancy. Vaginal cuff brachytherapy (VBT) is an adjuvant treatment for EC. Since a single-channel cylinder sometimes delivers inadequate dose coverage to the vaginal apex, three-dimensional (3D) printing technology can be used to achieve satisfactory dose distribution. Here, we report the first case of an EC patient with Herlyn-Werner-Wunderlich syndrome (HWWS) treated with VBT using 3D-printed applicators. Case Presentation Here, we present a case study of an endometrial cancer patient with HWWS who underwent surgery. During adjuvant radiotherapy, 3D-printed applicators were used in VBT. To accomplish the reconstruction of the source pathways on magnetic resonance imaging, catheters with copper sulfate were placed in two 3D-printed applicators. The early tolerance of this treatment was positive. During the 6-month follow-up, locoregional recurrence was not detected. Conclusion Our findings strongly indicate that VBT with 3D-printed applicators may be a reasonable treatment option for EC with HWWS.

Abstract
Recommendations for clinical practice, Nice/Saint-Paul-de-Vence 2022-2023: Management of localized endometrial cancer Endometrial cancer is the most frequent gynecological cancers in industrialized countries and its incidence increases. The newmolecularclassification allows determination of the risk of recurrence and helps orienting therapeutic management. Surgery remains the cornerstone of treatment. Minimally invasive approach must be preferred for stages I and II. Surgery includes hysterectomy with bilateral adnexectomy, sentinel lymph node biopsy even in high risk diseases and omentectomy for non-endometrioid tumors (except in case of clear cells tumors). Fertility preservation can be proposed in low grade, stage I tumors without myometrial involvement. In stage III/IV disease, lymph node debulking without totallymphadenectomy is indicated. In case of peritoneal carcinomatosis, first-line cytoreductive surgery is recommended if complete resection can be achieved. Adjuvant therapy is not recommended in low risk tumors. In intermediate risk tumors, curietherapy is indicated. In tumors with high-intermediate risk, curietherapy and external radiotherapy are indicated according to prognostic factors (stage II, lymphovascular invasion); adjuvant chemotherapy can be considered on a case-by-case basis. In high risk tumors, chemotherapy and external radiotherapy are recommended using a concomitant or sequential approach.

Abstract
Endometrial cancer is one of the most common cancers among women. The International Collaboration on Cancer Reporting (ICCR) developed a standardized endometrial cancer data set in 2011, which provided detailed recommendations for the reporting of resection specimens of these neoplasms. A new data set has been developed, which incorporates the updated 2020 World Health Organization Classification of Female Genital Tumors, the Cancer Genome Atlas (TCGA) molecular classification of endometrial cancers, and other major advances in endometrial cancer reporting, all of which necessitated a major revision of the data set. This updated data set has been produced by a panel of expert pathologists and an expert clinician and has been subject to international open consultation. The data set includes core elements which are unanimously agreed upon as essential for cancer diagnosis, clinical management, staging, or prognosis and noncore elements which are clinically important, but not essential. Explanatory notes are provided for each element. Adoption of this updated data set will result in improvements in endometrial cancer patient care.

Abstract
PURPOSE To evaluate the role and technique of a vaginal cuff brachytherapy (VB) boost to adjuvant external beam (EB) radiation for endometrial cancer through a systematic review. METHODS AND MATERIALS Relevant trials were identified through a systematic search of the literature. RESULTS A total of 21 prospective and retrospective studies which had a patient cohort undergoing EB + VB was identified to evaluate for rates of vaginal and pelvic recurrences, overall survival, and toxicity. Additional database studies were utilized to demonstrate differences in local control and overall survival between EB and EB + VB. CONCLUSIONS While there is limited prospective evidence to guide the use of a VB boost after EB, the evidence suggests that patients with a higher risk of a vaginal recurrence such as those with cervical stromal involvement in select Stage III patients may derive local control and survival benefits from a VB boost. Additional individual risk factors such as grade, histology, extent of invasion, margin status, age, and the use of lower doses of EB should be considered when deciding when to add a VB boost.

Abstract
Simple Summary There are various society-specific guidelines addressing adjuvant brachytherapy (BT) after surgery for endometrial cancer (EC). However, these recommendations are not uniform. Against this background, clinicians need to make decisions despite gaps between best scientific evidence and clinical practice. We analysed decision criteria influencing the selection for adjuvant radiotherapy among European radiation oncology experts. For this, GEC-ESTRO provided 19 European radiation oncology experts on gynaecological brachytherapy for decision-making analyses. The manuscript presents patterns in decision-making among these experts and demonstrates areas of consensus/discrepancies. We also analysed dose prescription and techniques of brachytherapy. This analysis is of special value as the objective approach enabled us to obtain an unbiased description of decision-making among the specialists (the study was not aimed to create or enforce a consensus). The manuscript provides valuable insight into clinical decision-making with a high impact on treatment selection, as expected differences between experts were observed. With this manuscript we are able to visualize and quantify these. This information is relevant for interdisciplinary discussions. Abstract Background: There are various society-specific guidelines addressing adjuvant brachytherapy (BT) after surgery for endometrial cancer (EC). However, these recommendations are not uniform. Against this background, clinicians need to make decisions despite gaps between best scientific evidence and clinical practice. We explored factors influencing decision-making for adjuvant BT in clinical routine among experienced European radiation oncologists in the field of gynaecological radiotherapy (RT). We also investigated the dose and technique of BT. Methods: Nineteen European experts for gynaecological BT selected by the Groupe Européen de Curiethérapie and the European Society for Radiotherapy & Oncology provided their decision criteria and technique for postoperative RT in EC. The decision criteria were captured and converted into decision trees, and consensus and dissent were evaluated based on the objective consensus methodology. Results: The decision criteria used by the experts were tumour extension, grading, nodal status, lymphovascular invasion, and cervical stroma/vaginal invasion (yes/no). No expert recommended adjuvant BT for pT1a G1-2 EC without substantial LVSI. Eighty-four percent of experts recommended BT for pT1a G3 EC without substantial LVSI. Up to 74% of experts used adjuvant BT for pT1b LVSI-negative and pT2 G1–2 LVSI-negative disease. For 74–84% of experts, EBRT + BT was the treatment of choice for nodal-positive pT2 disease and for pT3 EC with cervical/vaginal invasion. For all other tumour stages, there was no clear consensus for adjuvant treatment. Four experts already used molecular markers for decision-making. Sixty-five percent of experts recommended fractionation regimens of 3 × 7 Gy or 4 × 5 Gy for BT as monotherapy and 2 × 5 Gy for combination with EBRT. The most commonly used applicator for BT was a vaginal cylinder; 82% recommended image-guided BT. Conclusions: There was a clear trend towards adjuvant BT for stage IA G3, stage IB, and stage II G1–2 LVSI-negative EC. Likewise, there was a non-uniform pattern for BT dose prescription but a clear trend towards 3D image-based BT. Finally, molecular characteristics were already used in daily decision-making by some experts under the pretext that upcoming trials will bring more clarity to this topic.

Abstract
INTRODUCTION Chemotherapy plus radiation (Cis-RT + CP) did not demonstrate superiority in prolonging relapse-free survival compared to chemotherapy alone in patients with stage III or IVA endometrial carcinoma. The impact of treatment on quality of life (QOL), neurotoxicity (NTX) and psychometric properties of the gastrointestinal (GI) symptoms subscale during treatment and up to 1 year are described herein. METHODS QOL assessments were scheduled at baseline, 6 weeks (post completion of RT (Cis-RT + CP) or prior to cycle 3 (CP)), then 18 weeks (end of treatment) and 70 weeks (1 year after the end of treatment) after starting treatment. QOL instruments included the FACT-En TOI, FACT/GOG-neurotoxicity (Ntx) subscale (short), and the gastrointestinal (GI) symptoms subscale. RESULTS At the end of treatment, patients receiving Cis-RT + CP reported a statistically significant decreased QOL when compared to CP. The decline in QOL was reflected in physical well-being, functional well-being, and endometrial cancer specific concerns, but the minimally important differences (MID) were not considered clinically meaningful. Patients in both groups reported increased chemotherapy-induced Ntx symptoms with the CP group having worse scores and reaching peak symptoms at the time of chemotherapy completion. Patients on Cis-RT + CP reported statistically significantly worse GI symptoms after radiation therapy compared to patients on CP, this occurred across assessment intervals, though the MID was not meaningful. Psychometric evaluations indicated that the GI symptom scale is reliable, valid, and responsive to change. CONCLUSIONS PROs indicate that the chemoradiotherapy group experienced worse HRQoL and GI toxicity compared to patients randomized to chemotherapy alone for locally advanced endometrial cancer though based on the MID, these were not clinically meaningful differences. The GI symptom subscale was a reliable and valid scale that has value for future trials. TRIAL REGISTRATION NCT00942357.

[PMID: 33781714 DOI: 10.1016/j.brachy.2021.02.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 01/24/2021] [Accepted: 02/18/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVES To determine which patients with stage III endometrial cancer receiving adjuvant chemotherapy derive benefit from the addition of vaginal brachytherapy, as stage III is a highly heterogeneous population with substantial variations in practice. METHODS Patients with FIGO stage III endometrial carcinoma diagnosed 2004-2016 who underwent at least total hysterectomy and adjuvant multiagent chemotherapy were identified in the National Cancer Database. The primary outcome was overall survival according to receipt of brachytherapy, stratified by histologic type, pathological features, and status of pelvic external beam radiotherapy (EBRT), and analyzed using the Kaplan-Meier method and Cox multivariable regression. RESULTS In total, 9369 patients were identified (24% stage IIIA, 5% stage IIIB, 71% stage IIIC; 61% endometrioid, 39% nonendometrioid histology), and 28% received brachytherapy. In the endometrioid cohort, brachytherapy was associated with a 5% absolute increase in 3-year overall survival (87% vs. 82%, p < 0.0001), which persisted in multivariable analysis (adjusted hazard ratio 0.74, 95% confidence interval 0.64-0.84, p < 0.0001). The benefit of brachytherapy was greater in patients not also receiving EBRT, and in patients with vaginal/parametrial extension, grade 3 disease, lymphovascular invasion, and/or deep myometrial invasion. In the nonendometrioid cohort, brachytherapy was associated with a significant survival benefit in univariable but not multivariable analysis, regardless of EBRT status or pathological features. CONCLUSIONS Factors predictive of brachytherapy benefit were endometrioid histology and pathological risk factors for local recurrence. Additionally, brachytherapy appeared more beneficial in patients not already receiving pelvic EBRT. Further research is warranted to determine which stage III patients may be best served by brachytherapy, EBRT, or both.

Neoadjuvant radiotherapy and brachytherapy in endometrial cancer with gross cervical involvement: a CHIRENDO research group study. Int J Gynecol Cancer 2020; 31:78-84. [PMID: 33127863 DOI: 10.1136/ijgc-2020-001797] [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: 06/26/2020] [Revised: 09/28/2020] [Accepted: 09/30/2020] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Historically, radical hysterectomy followed by adjuvant radiotherapy has been offered to patients with endometrial cancer who have gross cervical involvement; however, this approach is known to carry considerable morbidity. Neoadjuvant radiotherapy followed by extra-fascial hysterectomy has been proposed as an alternative treatment but has been poorly studied to date. OBJECTIVE To evaluate the locoregional control rate associated with neoadjuvant radiotherapy followed by extra-fascial hysterectomy. METHODS A retrospective cohort study of 30 patients with endometrial cancer with gross cervical involvement treated between May 2006 and January 2016 was performed. Eligible patients were those aged >18 years with non-metastatic endometrial adenocarcinoma and gross cervical disease treated with curative intent at the Centre hospitalier de l'Université de Montréal. Treatment protocol consisted of pelvic neoadjuvant radiotherapy and high-dose rate brachytherapy followed by extra-fascial hysterectomy. Kaplan-Meier curves were used for survival analysis. RESULTS The median age was 60 (range 37-82) and median body mass index was 32 kg/m2 (range 16-55). Twenty-four (80%) patients were diagnosed with a positive cervical/endocervical biopsy. Clinical staging confirmed 36.7% (n=11) as stage II, 20% (n=6) stage IIIB, 30% (n=9) stage IIIC1, and 13.3% (n=4) stage IIIC2. Seventy-seven per cent (n=23) of patients had an endometrioid histology. Locally advanced disease was identified by imaging alone in six patients. Rates of parametrial, adnexal, vaginal, and nodal invasion were 10% (n=3), 6.7% (n=2), 13.3% (n=4), and 43.3% (n=13) at diagnosis, respectively. All patients completed pelvic radiotherapy (13.3% extended field) and 90% received brachytherapy. Twenty per cent (n=6) of surgeries were performed using minimal invasive technique. On surgical specimen, 63.3% (n=19) had complete cervical response, 90% (n=27) had negative margins, and 10% (n=3) had residual nodal involvement. Median follow-up time was 62 months (range 1-120). Six recurrences were identified; all except one involved distant failure, and two with locoregional failure. Five-year locoregional control rate, disease-free, overall, and disease-specific survival were 90.5%, 78.5%, 92.6%, and 96.2%, respectively. Two patients (6.7%) had grade 3+ acute radiation-related complications (all grade 3). Grade 3+ post-operative morbidity was noted in 2 (6.7%) patients. CONCLUSIONS Neoadjuvant radiotherapy followed by extra-fascial hysterectomy offers good locoregional control with low treatment-related morbidity in patients with endometrial cancer with overt cervical involvement.

Abstract
INTRODUCTION The purpose of this study is to describe the patterns of practice in Australia and New Zealand for post-operative radiotherapy in endometrial cancer with cervical stromal involvement. METHODS A ten-item survey including five clinical case scenarios in endometrial cancer with cervical stromal invasion was emailed to Royal Australian and New Zealand College of Radiologists (RANZCR) radiation oncologists in 2018. Responses were analysed to determine relative frequency distributions and preferred adjuvant treatment modalities for the clinical case scenarios. RESULTS A total of 65 respondents initiated the survey with 27 respondents treating more than 11 endometrial cancer cases annually. Only 31 respondents answered all five clinical case scenarios. Preferred adjuvant radiotherapy modalities varied for the Stage II cases between vault brachytherapy (VB), pelvic external beam radiotherapy (EBRT) or a combination. For the stage IIIA and IIIC1 cases, the majority recommended pelvic EBRT with or without VB boost (79% and 77%), and of these, most combined with chemotherapy (61% and 88%). For 4 of the 5 case scenarios, when pelvic EBRT was offered, most recommended a VB boost. CONCLUSION This patterns of practice survey suggests variability in adjuvant radiotherapy recommendations in endometrial cancer with cervical involvement, particularly in cases where there is lack of randomised data and discrepancies in consensus guidelines.

Abstract
This study aimed to evaluate the value of lymph node (LN) number as a predictor for adjuvant treatment in node-positive endometrial cancer. Data of 441 patients diagnosed with International Federation of Gynaecology and Obstetrics (FIGO) stage IIIC endometrial cancer and who underwent adjuvant chemotherapy alone or chemoradiotherapy between 2009 and 2015 from the Taiwan Cancer Registry were reviewed. The patients were stratified based on the number of positive LN as follows: 1, 2-5, and ≥ 6. The overall survival (OS) was analysed using the Kaplan-Meier method and the Cox proportional hazards model. In multivariable analysis, chemoradiotherapy was independently associated with improved OS (hazard ratio [HR]: 0.62, 95% confidence interval [CI]: 0.43-0.90; p = 0.01) compared with chemotherapy alone. Patients with ≥ 6 positive LNs were associated with a worse OS (HR: 2.22, 95% CI: 1.25-3.95; p = 0.006) and those with 2-5 LNs were not associated with a worse OS (HR: 1.56, 95% CI: 0.94-2.59; p = 0.09) compared to patients with one LN. When stratified based on LN number, chemoradiotherapy was found to significantly improve the 5-year OS of patients with ≥ 6 positive LNs compared to chemotherapy alone (35.9% vs. 70.0%, p < 0.001). No significant differences between chemotherapy alone and chemoradiotherapy were observed in 5-year OS among patients with one LN (73.1% vs. 80.8%, p = 0.31) or 2-5 positive LNs (71.4% vs. 75.7%, p = 0.68). Lymph node number may be used to identify node-positive endometrial cancer patients who are likely to have improved OS with intensification of adjuvant therapy.

Abstract
PURPOSE OF REVIEW This article reviews and interprets studies on adjuvant treatment of endometrial cancer published during the last 18 months. RECENT FINDINGS For patients with intermediate and high intermediate risk endometrial cancer, vaginal brachytherapy remains the adjuvant therapy of choice. New molecular markers might help to define patients in this group for whom observation only is sufficient and women who might have benefitted from external beam radiotherapy. Preliminary results from large randomized controlled trials have shown that in early stage, high-risk endometrial cancer the addition of chemotherapy to external beam radiotherapy (EBRT) did not improve survival. The combination of vaginal brachytherapy with three courses of chemotherapy resulted in similar progression-free and overall survival (3 years) as EBRT. In stage III high-risk endometrial cancer, the addition of chemotherapy to EBRT improved failure-free survival but not overall survival (immature data). Chemotherapy alone had the same efficacy concerning progression-free and overall survival (immature data). SUMMARY Three large randomized clinical trials on the role of adjuvant radio and/or chemotherapy have so far provided only immature results. Discussions about changes of clinical practice should be postponed until mature data from all three trials are available. The impact of new molecular markers for risk stratification will be assessed in ongoing RCTs.

Abstract
An interstitial brachytherapy approach for gynecologic cancers is typically considered for patients with lesions exceeding 5 mm within tissue or that are not easily accessible for intracavitary applications. Recommendations for treating gynecologic malignancies with this approach are available through the American Brachytherapy Society, but vary based on available resources, staffing, and logistics. The intent of this manuscript is to share the collective experience of 3 academic centers that routinely perform interstitial gynecologic brachytherapy. Discussion points include indications for interstitial implants, procedural preparations, applicator selection, anesthetic options, imaging, treatment planning objectives, clinical workflows, timelines, safety, and potential challenges. Interstitial brachytherapy is a complex, high-skill procedure requiring routine practice to optimize patient safety and treatment efficacy. Clinics planning to implement this approach into their brachytherapy practice may benefit from considering the discussion points shared in this manuscript.

LVSI positive and NX in early endometrial cancer: Surgical restaging (and no further treatment if N0), or adjuvant ERT? Gynecol Oncol 2019; 156:243-250.

Abstract
Early endometrial cancer has an overall survival of greater than 80% (1). One of the poor prognostic factors that may be associated with the 20% who do not survive 5 years is the presence of lymphovascular space invasion (LVSI). LVSI is associated with increased nodal metastasis and decreased progression free survival (PFS) and overall survival (OS). (2-8). Therefore, unstaged, LVSI positive early endometrial cancer requires additional management with either completion of staging with lymphadenectomy or adjuvant radiation. We focus on reviewing the management of natural history and management of early endometrial cancer followed by the prognostic impact of LVSI, management options and recommendations.

Abstract
PURPOSE This survey aimed to document the current practice patterns of postoperative radiotherapy (RT), including vaginal vault brachytherapy (VVB) and external beam radiotherapy (EBRT), in the management of patients with endometrial cancer. METHODS AND MATERIALS A 30-item, multiple choice survey querying RT prescribing practices and planning techniques was distributed electronically to American Brachytherapy Society members in December 2018. RESULTS Seventy-five surveys from 62 centers were completed. Eighty-nine percent of respondents practiced within the USA or Canada. Most (79%) respondents indicated a preference for recommending adjuvant VVB alone in FIGO Stage IB, Grade 2 margin and lymphovascular space invasion (LVSI) negative disease. For FIGO Stage IB, Grade 3, LVSI-positive disease, most respondents preferred incorporating EBRT either alone (33%) or with VVB (28%). For IIIC1, margin positive disease, VVB in addition to EBRT was most commonly recommended (75%). When planning adjuvant EBRT, 49% utilized CT simulation with both bladder full and empty. Internal target volume was utilized by 53%. Volumetric modulated arc therapy (53%) or intensity-modulated radiotherapy (19%) were commonly used planning techniques. The most common dose prescription was 45 Gy in 25 fractions (57%). When treating with VVB, 49% determined applicator size at the time of brachytherapy. Sixty-four percent planned treatments based on CT imaging with the applicator in situ and 33% repeated CT imaging before each subsequent fraction. The most common prescription was 21 Gy in three fractions prescribed to 0.5 cm depth (43%). CONCLUSIONS This study identified variability in treatment recommendations and in both EBRT and VVB simulation and planning processes in postoperative endometrial cancer.

Abstract
Objective Locally advanced endometrioid adenocarcinoma (LA-EAC) accounts for the majority of deaths for this cancer, yet there is no consensus on adjuvant treatment after surgery. Past studies suggest that combined modality treatment (CMT) may improve outcomes over treatment with chemotherapy (CT) or radiation therapy (RT, either external beam radiotherapy [EBRT] or vaginal brachytherapy [VBT]) alone. Using a large US-based population-based registry, we evaluated adjuvant CMT in LA-EAC and the relative benefit of regional EBRT compared to focused VBT. Methods We studied patients diagnosed with Stage III LA-EAC between 2004 and 2013 from the National Cancer Data Base (NCDB). We used Cox regression and a log-rank test to assess survival based on treatment with CT alone, EBRT alone, VBT alone, or CMT with EBRT and/or VBT. We used a χ2 test to compare covariates between patients receiving CMT with EBRT or VBT. Results Patients who received CMT had better survival than those who received CT or EBRT/VBT alone. Compared to CMT with VBT, patients who received CMT with EBRT were slightly older and had more advanced-stage or positive nodes, and fewer had lymph node surgery. We found no survival difference between CMT with EBRT and CMT with VBT even when categorizing patients as high or low risk according to age, grade, and stage (low-risk p=0.3460; high-risk p=0.2158). Conclusion CMT was associated with superior survival outcomes compared to monotherapy. We observed no survival difference between radiation modalities in CMT, which highlights the effectiveness of a more focused treatment like brachytherapy.

Adjuvant chemoradiotherapy versus radiotherapy alone for women with high-risk endometrial cancer (PORTEC-3): final results of an international, open-label, multicentre, randomised, phase 3 trial. Lancet Oncol 2018; 19:295-309. [PMID: 29449189 PMCID: PMC5840256 DOI: 10.1016/s1470-2045(18)30079-2] [Citation(s) in RCA: 368] [Impact Index Per Article: 61.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Revised: 11/24/2017] [Accepted: 11/30/2017] [Indexed: 12/14/2022]
Abstract
Background Although women with endometrial cancer generally have a favourable prognosis, those with high-risk disease features are at increased risk of recurrence. The PORTEC-3 trial was initiated to investigate the benefit of adjuvant chemotherapy during and after radiotherapy (chemoradiotherapy) versus pelvic radiotherapy alone for women with high-risk endometrial cancer. Methods PORTEC-3 was an open-label, international, randomised, phase 3 trial involving 103 centres in six clinical trials collaborating in the Gynaecological Cancer Intergroup. Eligible women had high-risk endometrial cancer with FIGO 2009 stage I, endometrioid-type grade 3 with deep myometrial invasion or lymph-vascular space invasion (or both), endometrioid-type stage II or III, or stage I to III with serous or clear cell histology. Women were randomly assigned (1:1) to receive radiotherapy alone (48·6 Gy in 1·8 Gy fractions given on 5 days per week) or radiotherapy and chemotherapy (consisting of two cycles of cisplatin 50 mg/m2 given during radiotherapy, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2) using a biased-coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage of cancer, and histological type. The co-primary endpoints were overall survival and failure-free survival. We used the Kaplan-Meier method, log-rank test, and Cox regression analysis for final analysis by intention to treat and adjusted for stratification factors. The study was closed on Dec 20, 2013, after achieving complete accrual; follow-up is ongoing. PORTEC-3 is registered with ISRCTN, number ISRCTN14387080, and ClinicalTrials.gov, number NCT00411138. Results 686 women were enrolled between Nov 23, 2006, and Dec 20, 2013. 660 eligible patients were included in the final analysis, of whom 330 were assigned to chemoradiotherapy and 330 were assigned to radiotherapy. Median follow-up was 60·2 months (IQR 48·1–73·1). 5-year overall survival was 81·8% (95% CI 77·5–86·2) with chemoradiotherapy versus 76·7% (72·1–81·6) with radiotherapy (adjusted hazard ratio [HR] 0·76, 95% CI 0·54–1·06; p=0·11); 5-year failure-free survival was 75·5% (95% CI 70·3–79·9) versus 68·6% (63·1–73·4; HR 0·71, 95% CI 0·53–0·95; p=0·022). Grade 3 or worse adverse events during treatment occurred in 198 (60%) of 330 who received chemoradiotherapy versus 41 (12%) of 330 patients who received radiotherapy (p<0·0001). Neuropathy (grade 2 or worse) persisted significantly more often after chemoradiotherapy than after radiotherapy (20 [8%] women vs one [1%] at 3 years; p<0·0001). Most deaths were due to endometrial cancer; in four patients (two in each group), the cause of death was uncertain. One death in the radiotherapy group was due to either disease progression or late treatment complications; three deaths (two in the chemoradiotherapy group and one in the radiotherapy group) were due to either intercurrent disease or late treatment-related toxicity. Interpretation Adjuvant chemotherapy given during and after radiotherapy for high-risk endometrial cancer did not improve 5-year overall survival, although it did increase failure-free survival. Women with high-risk endometrial cancer should be individually counselled about this combined treatment. Continued follow-up is needed to evaluate long-term survival.

Abstract
Endometrial cancer (EC) is one of the most common gynecological cancers among women in the developed countries. Vaginal cuff is the main location of relapses after a curative surgical procedure and postoperative radiation therapy have proven to diminish it. Nevertheless, these results have not translated into better survival results. The preeminent place of vaginal cuff brachytherapy (VCB) in the postoperative treatment of high- to intermediate-risk EC was given by the PORTEC-2 trial, which demonstrated a similar reduction in relapses with VCB than with external beam radiotherapy (EBRT), but VCB induced less late toxicity. As a result of this trial, the use of VCB has increased in clinical practice at the expense of EBRT. A majority of the clinical reviews of VCB usually address the risk categories and patient selection but pay little attention to technical aspects of the VCB procedure. Our review aimed to address both aspects. First of all, we described the risk groups, which guide patient selection for VCB in clinical practice. Then, we depicted several technical aspects that might influence dose deposition and toxicity. Bladder distension and rectal distension as well as applicator position or patient position are some of those variables that we reviewed.
