Purpose: Clinical drawings are integral part of image-guided adaptive brachytherapy (IGABT) of cervical cancer. It was used in EMBRACE study protocol as a useful tool. In our study clinical drawings from EMBRACE study were modified to include scales in all the dimensions for more accurate representation of various tumor related volumes. The aim of the present study was to understand patterns of tumor regression and relationship between gross tumor at diagnosis (GTVD) and high-risk clinical target volume (CTV-T
HR )/intermediate-risk clinical target volume (CTV-TIR ) in brachytherapy (BRT), using modified clinical drawings. Material and methods: 42 cervical cancer patients, staged as FIGO IIB-IIIB according to EMBRACE study, were enrolled. Advanced schematic 3D mapping diagram (3D-MD) in axial, coronal, and sagittal orientations, with a measurement scale (grid with 10 mm distance) for precise assessment and documentation was applied (through MRI at diagnosis and during brachytherapy). Dimensions, including height, width, and thickness as well as volumes (GTVD, CTV-THR and CTV-TIR ) were compared both qualitatively and quantitatively. Results and conclusions: We found qualitative and quantitative correlation of the dimensions of final CTV-THR with initial GTVD. Meticulous mapping of tumor volumes can provide useful insights to CTV-THR volume during brachytherapy. [ABSTRACT FROM AUTHOR]- Published

Abstract: Purpose: It has been shown that a cumulative dose of ⩾87Gy (EQD2) of external beam radiotherapy (EBRT) and image guided adaptive brachytherapy (IGABT) to the high risk clinical target volume (HR CTV) confer a local control rate >95% in locally advanced cervical cancer. This study examines the dose distribution within the HR CTV and intermediate (IR) CTV in patients with cervical cancer treated with definitive EBRT +/− concomitant chemotherapy and MRI-based IGABT between patients with local recurrence (LR) and patients in continuous complete local remission (CCLR). Material and methods: From 1998 to 2010, 265 patients were treated with definitive EBRT +/− concomitant chemotherapy and IGABT. Twenty-four LRs were documented. For the statistical analysis all patients with LR were matched to patients in CCLR from our database according to the following criteria: FIGO stage, histology, lymph node status, tumour size and chemotherapy. DVH parameters (D50, D90, D98, D100) were reported for HR CTV and IR CTV. In order to report the minimum dose in the region where the recurrence occurred, the HR CTV/IR CTV were divided into four quadrants on transversal planes. The minimum dose at the HR CTV/IR CTV contour was measured (within the corresponding quadrant closest to the LR) in the treatment planning system. A mean minimum point dose (MPD) was calculated by averaging these measurements on four consecutive slices at the level of the recurrence for each of the 4 brachytherapy fractions. EQD2 doses were calculated by summation of all BT and external beam therapy fractions. For each matched patient in the control group the measurements were performed on the same quadrant and at the same level. Results: Sufficient image data were available for 21 LRs. Eight central failures and 13 non-central failures were observed. The mean D90 and D100 for HR CTV were 77Gy and 61Gy for patients with LR and 95Gy and 71Gy for patients in CCLR, respectively (p <0.01). The MPD for HR CTV was 72Gy for patients in the LR arm and 99Gy for patients in the CCLR arm (p <0.01). In the LR arm seven patients had a D90 for HR CTV ⩾87Gy, however, in only three patients the MPD was ⩾87Gy. Conclusion: This study demonstrated significant differences in local outcome according to the delivered dose. In 85% of the LRs systematic low dose regions with less than 87Gy were found at HR CTV contour. Systematic low dose regions leading to local recurrence could be detected even if a D90 HR CTV ⩾87Gy was applied. In addition to DVH parameters, inspection of the spatial dose distribution remains a key point in dose prescription. [Copyright &y& Elsevier]

Background. The aim of this pilot study was to assess tumour hypoxia in patients with cervical cancer before, during and after combined radio-chemotherapy and Magnetic Resonance Imaging (MRI) guided brachytherapy (BT) by use of the hypoxia Positron Emission Tomography (PET) tracer 18F-fluoroazomycin-arabinoside (18FAZA ). Material and methods. Fifteen consecutive patients with locally advanced cervical cancer referred for definitive radiotherapy (RT) were included in an approved clinical protocol. Stage distribution was 3 IB1, 1 IB2, 10 IIB, 1 IIIB, tumour volume was 55 cm3 (+/− 67, SD). Dynamic and static 18FAZA -PET scans were performed before, during and after external beam therapy (EBRT) and image guided BT +/− concomitant cisplatin. Dose was prescribed to the individual High Risk Clinical Target Volume (HR CTV) taking into account the dose volume constraints for adjacent organs at risk. Results. Five patients had visually identifiable tumours on 18FAZA -PET scans performed prior to radio-chemotherapy and four patients before brachytherapy. One of five 18FAZA PET positive patients had incomplete remission three months after RT, one had regional recurrence. Four of ten 18FAZA-PET negative patients developed distant metastases. The one patient with incomplete remission received 69 Gy (D90) in the HR CTV, whereas all other patients received mean 99 Gy (+/−12, SD). Conclusion. PET imaging with 18FAZA is feasible in patients with cancer of the uterine cervix. However, its predictive and prognostic value remains to be clarified. This applies in particular for the additional value of 18FAZA-PET compared to morphologic repetitive MRI within the setting of image guided high dose radiotherapy which may contribute to overcome hypoxia related radioresistance.

Purpose: The purpose was to evaluate patient- and treatment-related risk factors for physician-assessed and patient-reported gastrointestinal (GI) symptoms after radio(chemo)therapy and image guided adaptive brachytherapy in locally advanced cervical cancer.Methods and Materials: Of 1416 patients from the EMBRACE-I study, 1199 and 1002 were prospectively evaluated using physician-assessed (Common Terminology Criteria for Adverse Events [CTCAE]) and patient-reported (European Organization for Research and Treatment of Cancer [EORTC]) GI symptoms, respectively. CTCAE severe grade (grade [G] ≥3) events were pooled according to the location in the GI tract (anus/rectum, sigmoid, and colon/small bowel). CTCAE G ≥2 and EORTC "very much" and "quite a bit" plus "very much" scores (≥ "quite a bit") were analyzed for individual symptoms with Cox regression. Logistic regression was used for persistent G ≥1 and EORTC ≥ "quite a bit" symptoms, defined if present in at least half of follow-ups.Results: The incidence of G ≥3 events was 2.8%, 1.8%, and 2.3% for G ≥3 anus/rectum, sigmoid, and colon/small bowel events, respectively. Among G ≥2 symptoms, diarrhea and flatulence were the most prevalent (8.5% and 9.9%, respectively). Among patient-related factors, baseline morbidity, increasing age, smoking status, and low body mass index were associated with GI symptoms to varying degrees. Among treatment-related factors, rectum D2cm3 and the International Commission on Radiation Units and Measurements recto-vaginal reference point (ICRU RV-RP) correlated with G ≥3 anus/rectum events and moderate/persistent diarrhea, proctitis, bleeding, abdominal cramps, and difficulty in bowel control. Bowel D2cm3 correlated with G ≥3 sigmoid and colon/small bowel events and moderate/persistent diarrhea and flatulence. For external beam radiation therapy (EBRT), prescription dose correlated with G ≥3 anus/rectum, diarrhea, and difficulty in bowel control. Patients with large lymph-node boost (V57Gy) were at higher risk for G ≥3 sigmoid events, moderate/persistent diarrhea, proctitis, and cramps.Conclusions: The analysis showed that both EBRT and image guided adaptive brachytherapy contribute to GI symptoms after locally advanced cervical cancer treatment. Rectum D2cm3, ICRU RV-RP , and bowel D2cm3 are risk factors for GI morbidity. The risk for various symptoms was lower with an EBRT prescription of 45 Gy than 50 Gy and increased with larger V57Gy.

Purpose: To evaluate patient-reported sexual outcomes after chemoradiation therapy and image-guided adaptive brachytherapy for locally advanced cervical cancer in the observational, prospective, multicenter EMBRACE-I study.Methods and Materials: Sexual outcomes were assessed prospectively with the European Organization for Research and Treatment of Cancer Qualify of Life Questionnaire (EORTC-QLQ-CX24) at baseline and follow-up. Crude incidence and prevalence rates of sexual activity, vaginal functioning problems (dryness, shortening, tightening, pain during intercourse), and sexual enjoyment were evaluated. Associations between pain during intercourse and vaginal functioning problems or sexual enjoyment were calculated, pooling observations over all follow-ups (Spearman correlation coefficient). In patients who were frequently sexually active (≥50% of follow-ups), the effects of regular hormonal replacement therapy (HRT) on vaginal functioning problems were evaluated (Pearson χ2).Results: The analysis involved 1045 patients with a median follow-up of 50 months. Sexual activity was reported by 22% of patients at baseline and by 40% to 47% of patients during follow-up (prevalence rates). Vaginal functioning problems in follow-up were dryness (18%-21%), shortening (15%-22%), tightening (16%-22%), pain during intercourse (9%-21%), and compromised enjoyment (37%-47%). Pain during intercourse was significantly associated with vaginal tightening (r = 0.544), shortening (r = 0.532), and dryness (r = 0.408) and negatively correlated with sexual enjoyment (r = -0.407). Regular HRT was associated with significantly less vaginal dryness (P = .015), shortening (P = .024), pain during intercourse (P = .003), and borderline higher sexual enjoyment (P = .062).Conclusions: Vaginal functioning problems are associated with pain and compromised sexual enjoyment. Further effort is required for the primary prevention of vaginal morbidity with dose optimization and adaptation. Secondary prevention strategies, including HRT for vaginal and sexual health after radiation therapy in locally advanced cervical cancer, should be considered and sexual rehabilitation programs should be developed further.

BLADDER cancer , *INTERSTITIAL cystitis , *CERVICAL cancer , *CYSTITIS , *BLADDER , *FISTULA , *RADIOISOTOPE brachytherapy - Abstract
• Urinary morbidity after treatment of locally advanced cervical cancer is prevalent. • Bladder dose constraints based on a high level clinical evidence are not available. • EMBRACE I provides prospective morbidity data for analysis in a large cohort. • Individual physician and patient reported urinary endpoints were analysed in EMBRACE I. • Bladder fistula, bleeding and cystitis showed dose–effect with bladder D 2cm3. To identify patient- and treatment-related risk factors for fistula, bleeding, cystitis, pain and difficulty in voiding in locally advanced cervical cancer patients treated with radio(chemo)therapy and image-guided adaptive brachytherapy (IGABT). Morbidity within the EMBRACE-I study was prospectively reported for physician-assessed (CTCAE) fistula, bleeding and cystitis and patient-reported (EORTC) pain and difficulty in voiding. Analysis of risk factors was performed in patients without bladder infiltration. Risk factors were tested with Cox regression for grade (G) ≥ 3 cystitis, for G ≥ 2 fistula, bleeding and cystitis, and for EORTC "very much" and "quite a bit" or worse. Of 1416 patients enrolled, 1153 and 884 patients without bladder infiltration were evaluable for the analysis of CTCAE and EORTC items, respectively. Median follow-up was 48[3–120] months. Crude incidence rates for G ≥ 2 fistula, bleeding and cystitis were 0.7%, 2.7% and 8.8%, respectively, and 16% and 14% for "quite a bit" or worse pain and difficulty in voiding, respectively. Baseline urinary morbidity and overweight/obesity were significant risk factors for most endpoints. Bladder D 2cm3 correlated with G ≥ 2 fistula, bleeding and cystitis, while ICRU bladder point dose correlated with EORTC pain "quite a bit" or worse. An increase from 75 Gy to 80 Gy in bladder D 2cm3 resulted in an increase from 8% to 13% for 4-year actuarial estimate of G ≥ 2 cystitis. Clinical and treatment-related risk factors for bladder fistula, bleeding and cystitis were identified within a prospective and multi-institutional setting. A dose–effect was established with bladder D 2cm3 , reinforcing the importance of continued optimization during individualized IGABT planning. [ABSTRACT FROM AUTHOR]

• Urinary side effects after radiotherapy can rely on different bladder substructures. • EMBRACE I provides prospective morbidity data to study individual urinary symptoms. • Frequency and incontinence are frequent side effects in cervix cancer radiotherapy. • Limited clinical evidence supports the predictive value of ICRU Bladder point dose. • This analysis showed correlation of ICRU Bladder point dose with incontinence. To identify patient- and treatment-related risk factors and dose-effects for urinary frequency and incontinence in locally advanced cervical cancer (LACC) treated with radio(chemo)therapy and image-guided adaptive brachytherapy (IGABT). Physician-assessed (CTCAE) and patient-reported (EORTC) frequency and incontinence recorded in the EMBRACE-I study were analysed. Risk factors analysis was performed in patients without bladder infiltration and with baseline morbidity available. Cox regression was used for CTCAE grade (G) ≥ 3 and G ≥ 2 and for EORTC "very much" and "quite a bit" or worse. Logistic regression was used for late persistent morbidity defined when CTCAE G ≥ 1 or EORTC ≥ "quite a bit" were scored in at least half of follow-ups. Longitudinal data on 1153 and 884 patients were available for CTCAE and EORTC analysis, respectively. Median follow-up was 48[3-120] months. Crude incidence rates of G≥2 were 13% and 11% for frequency and incontinence, respectively. Baseline morbidity and overweight-obesity were risk factors for both symptoms. Elderly patients were at higher risk for incontinence. Patients receiving conformal-radiotherapy were at higher risk for frequency. ICRU bladder point (ICRU-BP) dose was a stronger predictor for incontinence than bladder D 2cm3. The 5-year actuarial estimate of G ≥ 2 incontinence increased from 11% to 20% with ICRU-BP doses > 75 Gy compared to ≤ 65 Gy. Frequency showed weaker associations with dose. ICRU-BP dose, in addition to clinical parameters, is a risk factor for urinary incontinence and shows a dose–effect after radio(chemo)therapy and IGABT. ICRU-BP dose should be monitored during treatment planning alongside volumetric parameters. Frequency seems associated with larger irradiated volumes. [ABSTRACT FROM AUTHOR]

• Local and pelvic control in FIGO 1994 stage IB were ≥95% with acceptable morbidity. • We found no isolated local relapse. Pelvic failure occurred in 3%. Most relapses were systemic. • Results of modern brachytherapy in early cervical cancer parallel those of modern surgery. Multiple treatment options are used in early local-stage cervical cancer, including combinations of surgery with neoadjuvant/adjuvant radiotherapy and chemotherapy. Our aim was to determine the outcome for definitive chemoradiation with image guided brachytherapy (IGBT). FIGO 1994 staging system was used in our study. We included 123 patients with stage IB cervical cancer, treated at 12 centers with external beam radiotherapy (EBRT) ± Chemotherapy and IGBT. Three- and 5-year actuarial local control (LC), pelvic control (PC), overall survival (OS), cancer-specific survival (CSS) and late morbidity (CTCAE v 3.0) were computed. Median age was 48 (23–82) years. FIGO 1994 stage distribution was: IB1 68% and IB2 32%; 41% of the entire cohort had nodal metastases and 73% squamous-cell carcinoma. MRI-based tumor size was >40 mm in 63%. Median EBRT dose was 45 (40–50) Gy; 84% received chemotherapy. At IGBT, mean CTV-HR D90 was 93 ± 17 Gy (EQD2 10). D2cc for bladder was 76 ± 14 Gy, rectum 66 ± 11 Gy, sigmoid 66 ± 10 Gy, bowel 67 ± 7 Gy (EQD2 3). At 43-months median follow-up, 9% of patients had systemic, 6% paraaortic, 3% pelvic-nodal and 2% local failure. Five-year LC was 98%, PC 96%, CSS 90%, OS 83%. Intestinal G3-–4 morbidity was 8%, urinary 7% and vaginal 0%. Chemoradiation with IGBT for FIGO 1994 stage IB cervical cancer leads to excellent loco-regional control with limited morbidity. In IB node-negative disease, it can be regarded equivalent to surgery in terms of oncologic outcome. In tumors with unfavorable pre-treatment characteristics, chemoradiation is the first choice to avoid combining surgery with adjuvant therapy. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate patient- and treatment-related risk factors associated with incidence and persistence of late diarrhea after radiochemotherapy and image guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer.Materials and Methods: Of 1416 patients from the EMBRACE I study, 1199 were prospectively evaluated using physician-reported (Common Terminology Criteria for Adverse Events version 3 [CTCAEv3]) assessment for diarrhea; median follow-up 48 months. Patient-reported outcome (EORTC) was available in 900 patients. Incidence of CTCAE G≥2, G≥3, and EORTC "very much" diarrhea was analyzed with Cox proportional hazards regression. Binary logistic regression was used for analysis of persistent G≥1 and EORTC "quite a bit" - "very much" (≥"quite a bit") diarrhea, defined if present in at least half of all follow-ups.Results: Crude incidences of G≥2 and G≥3 diarrhea were 8.3% and 1.5%, respectively, and 8% of patients reported "very much" diarrhea. Persistent G≥1 and ≥"quite a bit" diarrhea was present in 16% and 7%, respectively. Patient-related risk factors were baseline diarrhea, smoking, and diabetes with hazard ratios of 1.4 to 7.3. Treatment-related risk factors included prescribed dose, V43 Gy, V57 Gy (lymph node boost), and para-aortic irradiation for external beam radiation therapy (EBRT). G≥2 diarrhea at 3 years increased from 9.5% to 19.9% with prescribed dose 45 Gy versus 50 Gy, 8.7% to 14.0% with V43 Gy <2500 cm3 versus >3000 cm3 and 9.4% to 19.0% with V57 Gy <165 cm3 versus ≥165 cm3. Brachytherapy-related bowel and rectum D2cm3 were also associated with diarrhea.Conclusion: Dose and volume effects have been established for late diarrhea after radiochemotherapy and IGABT in both CTCAE and EORTC reporting. The risk of diarrhea was lower with a pelvic EBRT prescription of 45 Gy, and higher with larger lymph node boosts volumes (ie, ≥165 cm3). The importance of EBRT volumes as determinants of late toxicity underline the need for continuous quality assurance of target contouring, dose planning, and conformity. The findings of brachytherapy dosimetric factors related to the intestines may become more important with highly conformal EBRT. [ABSTRACT FROM AUTHOR]- Published

• The survey results described in the manuscript captures the heterogeneity in the clinical practice of oligometastatic and oligorecurrent cervical cancer. • This survey will help to define the role of radiation therapy in oligometastatic and oligorecurrent cervical cancer. • This survey highlights the desire of radiation oncologists over the globe to practice stereotactic radiation therapy in oligometastatic disease and will help to plan future clinical trials. In the metastatic or recurrent cervical cancer, systemic chemotherapy constitutes the main treatment. Though there is an increasing use of high dose external radiation and brachytherapy in the metastatic setting, no consensus exists. A 17-item survey was designed with additional case-based questions to explore present management of oligo-metastatic and oligo-recurrent cervix cancer within EMBRACE research group participating sites. The questions were designed to elicit prevailing practices in the management of de-novo oligo-metastasis and oligo-recurrent setting after completing the primary treatment of cervix cancer. The survey was sent electronically with two rounds of email reminders to respond over a 2-week survey period. The online survey was designed such that it was mandatory to complete all questions. The responses were recorded and results were summarized as proportions and summary statistics were generated. Twenty-two centers responded to this survey. A majority (90%) of respondents reported a low incidence of de-novo oligo-metastatic cervical cancer in their practice (<5%), with a higher proportion of patients with oligo-recurrence after completing primary treatment (5–10%). All responding sites preferred to treat pelvic disease in the de-novo oligo-metastatic setting albeit with different fractionation regimens. While 68.2% of respondents recommended chemo-radiation and brachytherapy, 31.8% considered additional systemic therapy. Overall 77.3% centers recommended the use of stereotactic ablative radiation therapy to oligo-metastasis. For out-of-field nodal recurrences, 63.7% of respondents considered treating with curative intent, while 59% preferred treating in-field recurrence with palliative intent. A vast majority of the participating centers (90%) have stereotactic radiation therapy capacity and would consider a clinical trial addressing oligo-metastatic and oligo-recurrent cervical cancer. Although contemporary practice is variable, a substantial proportion of EMBRACE centers consider high dose radiation in de-novo metastatic and oligo-recurrence settings. However, there is clear need for a joint clinical protocol and prospective studies to address the role of high dose radiation within oligo-recurrent and oligo-metastatic scenarios.

REPORTING of diseases , *CERVICAL cancer , *RADIOISOTOPE brachytherapy , *CANCER education - Abstract
In 2008, the GEC ESTRO Gyn network launched the first multiinstitutional, observational, and prospective international study on MRI-guided brachytherapy in locally advanced cervical cancer patients (EMBRACE-I). EMBRACE-I was followed by EMBRACE-II from 2016 and ongoing. Among the aims of the EMBRACE studies are to benchmark morbidity outcomes and develop dose-volume effects and predictive models for morbidity. The EMBRACE studies collect both physician (CTCAE v.3) and patient (EORTC QLQ-C30/CX24) reported outcomes, including baseline information, in a regular follow-up schedule. The EMBRACE studies feature high numbers of patients (EMBRACE-I N = 1416, EMBRACE-II N = 1500 expected) enrolled from many institutions worldwide (EMBRACE-I n = 23, EMBRACE-II n = 45). This large-scale multiinstitutional approach offers a unique opportunity to investigate and develop new strategies for improving the quality of assessment and reporting of morbidity. This report presents an overview of the challenges and pitfalls regarding the assessment and reporting of morbidity encountered during more than a decade of development and research activities within the EMBRACE consortium. This includes the recognition and evaluation of inconsistencies in the morbidity assessment, and consequently, the provision of assistance and training in the scoring procedure to reduce systematic assessment bias. In parallel, a variety of methodological approaches were tested to comprehensively summarize morbidity outcomes, and a novel approach was developed to refine dose-effect models and risk factor analyses. The purpose of this report is to present an overview of these findings, describe the learning process, and the strategies that have consequently been implemented regarding educational activities, training, and dissemination.

Primary vaginal cancer is a rare cancer and clinical evidence to support recommendations on its optimal management is insufficient. Because primary vaginal cancer resembles cervical cancer in many aspects, treatment strategies are mainly adopted from evidence in locally advanced cervical cancer. To date, the organ-sparing treatment of choice is definitive radiotherapy, consisting of external beam radiotherapy and brachytherapy, combined with concurrent chemotherapy. Brachytherapy is an important component of the treatment and its steep dose gradient enables the delivery of high doses of radiation to the primary tumour, while simultaneously sparing the surrounding organs at risk. The introduction of volumetric CT or MRI image-guided adaptive brachytherapy in cervical cancer has led to better pelvic control and survival, with decreased morbidity, than brachytherapy based on x-ray radiographs. MRI-based image-guided adaptive brachytherapy with superior soft-tissue contrast has also been adopted sporadically for primary vaginal cancer. This therapy has had promising results and is considered to be the state-of-the-art treatment for primary vaginal cancer in standard practice. [ABSTRACT FROM AUTHOR]

• In locally advanced cervical cancer (LACC) with residual tumor in distal parametrium or pelvic wall disease after concurrent radio-chemotherapy (CCRT) (category II). • Brachytherapy is technically challenging. • Our report highlights the clinical feasibility and outcome of patients treated at 2 Institutions. • BT was delivered using Vienna II BT Applicator (Vienna ring with add on cap) based IGABT. • This approach results in optimal outcome and acceptable grade 3 toxicities. Recent evidence from EMBRACE shows that around 16% patients with locally advanced cervical cancer (LACC) have residual tumor in distal parametrium (DP) and pelvic wall disease (LPW) after concurrent radio-chemotherapy (CCRT). Adequate target coverage with standard brachytherapy approaches represents a challenge. Therefore, we modified the Vienna I applicator with an add-on cap allowing for additional oblique needles into the DP/LPW (Vienna II). We report here the feasibility and clinical outcomes using Vienna II applicator in LACC patients treated in 2 institutions. 69 patients with residual disease in DP/LPW after CCRT were accrued. FIGO (2009) stage was 26% IIB, 52% III, 15% IVA, 7% IVB (para-aortic nodes). At diagnosis 91% had disease involving DP/LPW. After CCRT, patients underwent image guided adaptive brachytherapy (IGABT) using Vienna II applicator. IGABT details, acute complications, dose volume parameters and clinical outcome variables were compiled and analyzed. Residual DP/LPW disease at BT was found in 90% patients. Median total number of needles were 7 [3–15], oblique 4 [1–7]. Manageable intraoperative utero-vaginal complications occurred in 8 patients and manageable arterial bleeding in 6 patients during removal. Mean distance between tandem and outer contour of CTV HR was 38 mm and mean CTV HR (±SD) volume was 69 ± 32 cm3. The mean D 90 CTV HR was 86 ± 7 Gy (EQD2) and mean (±SD) D 2cm 3 (Gy, EQD2) 86 ± 12, 68 ± 7, 68 ± 9 for bladder, rectum and sigmoid respectively. Actuarial LC, PFS, OS at 3/5 years was 76/72%, 56/50%, 62/54% and G3-4 late toxicities (n = 23) were observed in 14 patients (20%). IGABT using Vienna II applicator allows for appropriate target coverage in tumors extending into DP/LPW at the time of BT. Clinical use is feasible and results in good local control, DFS and OS with moderate rate of acute and late ≥G3 toxicity. [ABSTRACT FROM AUTHOR]

Highlights • Nodal failure rate after chemo-radiation and MRI guided BT is 11%. • Nodal failure rates for the N− and N+ group were 7 and 16% • Complete remission after treatment was seen in 95% of N+ patients. • Nodes at diagnosis were mainly located in the pelvis, nodal failures more often in PAO. • Forty-one percent of nodal failure patients had failure outside the treated volume. Abstract Purpose/Objective(s) To investigate the patterns of nodal failure in patients enrolled in the international multicentre EMBRACE study. Materials/Methods Nodal disease at diagnosis (N−, N+) and nodal failure were analysed per region (NF) (pelvic (parametrial, common iliac, internal/external iliac), inguinal and para-aortic (PAO)) in 1338 patients. Treatment consisted of chemo-radiation and MRI guided brachytherapy. PAO radiotherapy and/or nodal boost was left to the treating centre. At time of diagnosis 52% of patients had pathologic nodes. Frequency analyses were performed in relation to patient, primary tumour and nodal disease characteristics, and treatment related factors. Results Median follow up was 34 months and 83% of NF occurred within 24 months. At diagnosis 99% of the N+ patients had pathologic nodes in the pelvis and 14% in the PAO. NF pelvic and NF PAO were reported in 55% and 68% of patients with NF, respectively. Overall NF was reported in 152 patients (11%); 7 and 16% for N- and N+ patients. Of the patients with NF, 41% were located outside the elective target (39% PAO), 40% inside and 35% inside the nodal boost target. Twelve percent of N+ patients that received a nodal boost had a NF inside the nodal boost target. Conclusion Within the EMBRACE study cohort the overall number of patients developing nodal failure is low, significantly lower for N− compared to N+ patients. Pathological nodes at diagnosis are mainly located in the pelvis, whereas nodal failures are more often reported in the PAO region. About 40% of all nodal failures were reported outside the treatment targets. [ABSTRACT FROM AUTHOR]

CERVICAL cancer , *CANCER survivors , *QUALITY of life , *CHRONIC pain , *PATIENT reported outcome measures , *CANCER fatigue - Abstract
• Impact of morbidity on quality of life (QOL) of cancer survivors depends on severity and persistence. • Prospective data from EMBRACE-I allowed to assess the association for cervical cancer survivors. • All persistent symptoms were significantly associated with QOL aspects, but with different magnitude. • Role functioning and global health/general QOL were the most impaired aspects reported by patients. • Persistent pain and fatigue were more detrimental compared to other organ-related symptoms. To quantify the association of persistent morbidity with different aspects of quality of life (QOL) in locally advanced cervical cancer (LACC) survivors. Longitudinal outcome from the EMBRACE-I study was evaluated. Patient-reported symptoms and QOL were prospectively scored (EORTC-C30/CX24) at baseline and regular follow-ups. Physician-assessed symptoms were also reported (CTCAEv.3). Persistent symptoms were defined if present in at least half of the follow-ups. QOL items were linearly transformed into a continuous scale. Linear mixed-effects models (LMM) were applied to evaluate and quantify the association of persistent symptoms with QOL. Overall QOL deterioration was evaluated by calculating the integral difference in QOL over time obtained with LMM for patients without and with persistent symptoms. Out of 1416 patients enrolled, 741 with baseline and ≥ 3 late follow-ups were analyzed (median 59 months). Proportions of persistent EORTC symptoms ranged from 21.8 % to 64.9 % (bowel control and tiredness). For CTCAE the range was 11.3–28.6 % (limb edema and fatigue). Presence of any persistent symptom was associated with QOL, although with varying magnitude. Role functioning and Global health/QOL were the most impaired aspects. Fatigue and pain showed large differences, with reductions of around 20 % for most of the QOL aspects. Among organ-related symptoms, abdominal cramps showed the largest effect. Persistent symptoms are associated with QOL reductions in LACC survivors. Organ-related symptoms showed smaller differences than general symptoms such as fatigue and pain. In addition to optimizing treatment to minimize organ-related morbidity, effort should be directed towards a more comprehensive and targeted morbidity management. [ABSTRACT FROM AUTHOR]

Abstract: Background: To analyse the overall clinical outcome and benefits by applying protocol based image guided adaptive brachytherapy combined with 3D conformal external beam radiotherapy (EBRT)±chemotherapy (ChT). Methods: Treatment schedule was EBRT with 45–50.4Gy±concomitant cisplatin chemotherapy plus 4×7Gy High Dose Rate (HDR) brachytherapy. Patients were treated in the “protocol period” (2001–2008) with the prospective application of the High Risk CTV concept (D90) and dose volume constraints for organs at risk including biological modelling. Dose volume adaptation was performed with the aim of dose escalation in large tumours (prescribed D90>85Gy), often with inserting additional interstitial needles. Dose volume constraints (D2cc) were 70–75Gy for rectum and sigmoid and 90Gy for bladder. Late morbidity was prospectively scored, using LENT/SOMA Score. Disease outcome and treatment related late morbidity were evaluated and compared using actuarial analysis. Findings: One hundred and fifty-six consecutive patients (median age 58years) with cervix cancer FIGO stages IB–IVA were treated with definitive radiotherapy in curative intent. Histology was squamous cell cancer in 134 patients (86%), tumour size was >5cm in 103 patients (66%), lymph node involvement in 75 patients (48%). Median follow-up was 42months for all patients. Interstitial techniques were used in addition to intracavitary brachytherapy in 69/156 (44%) patients. Total prescribed mean dose (D90) was 93±13Gy, D2cc 86±17Gy for bladder, 65±9Gy for rectum and 64±9Gy for sigmoid. Complete remission was achieved in 151/156 patients (97%). Overall local control at 3years was 95%; 98% for tumours 2–5cm, and 92% for tumours >5cm (p =0.04), 100% for IB, 96% for IIB, 86% for IIIB. Cancer specific survival at 3years was overall 74%, 83% for tumours 2–5cm, 70% for tumours >5cm, 83% for IB, 84% for IIB, 52% for IIIB. Overall survival at 3years was in total 68%, 72% for tumours 2–5cm, 65% for tumours >5cm, 74% for IB, 78% for IIB, 45% for IIIB. In regard to late morbidity in total 188 grade 1+2 and 11 grade 3+4 late events were observed in 143 patients. G1+2/G3+4 events for bladder were n =32/3, for rectum n =14/5, for bowel (including sigmoid) n =3/0, for vagina n =128/2, respectively. Interpretation: 3D conformal radiotherapy±chemotherapy plus image (MRI) guided adaptive intracavitary brachytherapy including needle insertion in advanced disease results in local control rates of 95–100% at 3years in limited/favourable (IB/IIB) and 85–90% in large/poor response (IIB/III/IV) cervix cancer patients associated with a moderate rate of treatment related morbidity. Compared to the historical Vienna series there is relative reduction in pelvic recurrence by 65–70% and reduction in major morbidity. The local control improvement seems to have impact on CSS and OS. Prospective clinical multi-centre studies are mandatory to evaluate these challenging mono-institutional findings. [Copyright &y& Elsevier]
