• Adaptive target volume concept for EBRT and brachytherapy in primary vaginal cancer. • MRI is the imaging modality of choice for target volume delineation in brachytherapy. • Common terminology will facilitate multicenter research. External beam radiotherapy (EBRT) combined with brachytherapy has an essential role in the curative treatment of primary vaginal cancer. EBRT is associated with significant tumour shrinkage, making primary vaginal cancer suitable for image guided adaptive brachytherapy (IGABT). The aim of these recommendations is to introduce an adaptive target volume concept for IGABT of primary vaginal cancer. In December 2013, a task group was initiated within GYN GEC-ESTRO with the purpose to introduce an IGABT target concept for primary vaginal cancer. All participants have broad experience in IGABT and vaginal cancer brachytherapy. The target concept was elaborated as consensus agreement based on an iterative process including target delineation and dose planning comparison, retrospective analysis of clinical data and expert opinions. Gynaecological examination and MR imaging are the modalities of choice for local tumour assessment. A specific template for standardised documentation with clinical drawings for vaginal cancer was developed. The adaptive target volume concept comprises different response-related target volumes. For EBRT these are related to the primary tumour and the lymph nodes, while for IGABT these are related to the primary tumour and are consisting of the residual gross tumour volume (GTV-T res) and the high-, and intermediate risk clinical target volumes (CTV-T HR , CTV-T IR). This target concept for IGABT of primary vaginal cancer defines adaptive target volumes for volumetric dose prescription and should improve comparability of different radiotherapy schedules of this rare disease. A prospective evaluation of the target volume concept within a multicentre study is planned. [ABSTRACT FROM AUTHOR]

Purpose To compare the maximum high risk clinical target volume (CTV HR ) dimensions and image quality between magnetic resonance imaging (MRI), transrectal ultrasound (TRUS) and computed tomography (CT) in image guided adaptive brachytherapy (IGABT) of locally advanced cervical cancer. Material and methods All patients with locally advanced cervical cancer treated with radiochemotherapy and IGABT between 09/2012-05/2013 were included in this study. T2-weighted MRI (1.5 tesla), TRUS and CT were performed before (MRI preBT , TRUS preBT ) and/or after (MRI BT , TRUS BT and CT BT ) insertion of the applicator. 3D TRUS image acquisition was done with a customized US stepper device and software. The HR CTV was defined on 3D image sequences acquired with different imaging modalities by one blinded observer, in accordance to the GEC-ESTRO recommendations for MRI-based target volume delineation, as the complete cervical mass including the tumour, any suspicious areas of parametrial involvement and the normal cervical stroma. Maximum HR CTV width and thickness were measured on transversal planes. Image quality was classified using the following scoring system: Grade 0: not depicted, Grade 1: inability to discriminate, margin not recognizable, Grade 2: fair discrimination, margin indistinct, Grade 3: excellent discrimination, margin distinct. Descriptive statistics, mean differences between the groups, with MRI BT as reference, and a paired t -test were calculated. Results Images from 19 patients (FIGO IB: 3, IIB: 9, IIIB: 5, IVB: 2) were available for analysis. The mean difference in maximum HR CTV width of TRUS BT, TRUS preBT, MRI preBT, CT BT to MRI BT was 0.0 mm ± 4.7 (n.s.), −1.1 mm ± 5.6 (n.s.), 0.7 mm ± 6.4 (n.s.) and 13.8 mm ± 6.7 ( p < 0.001). The mean difference in maximum HR CTV thickness of TRUS BT, TRUS preBT, MRI preBT, CT BT to MRI BT was -3.4 mm ± 5.9 ( p = 0.037), −3.4 mm ± 4.2 ( p < 0.001), 2.0 mm ± 6.1 (n.s.) and 13.9 mm ± 6.3 ( p < 0.001). Mean scores of image quality of the target volume was 2.9 for TRUS preBT , 2.3 for TRUS BT , 2.9 for MRI preBT , 2.7 for MRI BT and 2.1 for CT BT . Conclusion For the assessment of the HR CTV in IGABT of cervical cancer, TRUS is within the intraobserver variability of MRI. TRUS is superior to CT as it yields systematically smaller deviations from MRI, with good to excellent image quality. Small differences of TRUS HR CTV thickness are likely related to differences in image slice orientation and compression of the cervix by the TRUS probe before insertion of the brachytherapy applicator.

Abstract: Purpose: In general late side-effects after prostate cancer radiotherapy are presented by the use of actuarial incidence rates. The aim of this analysis was to describe additional relevant aspects of late side effects after prostate cancer radiotherapy. Materials and methods: All 178 primary prostate-cancer patients were treated within the Austrian–German multicenter trial by three-dimensional radiotherapy up to a local dose of 70Gy (low/intermediate-risk) or 74Gy (high-risk), respectively. Late gastrointestinal/urogenital (GI/GU) side-effects were prospectively assessed by the use of EORTC/RTOG score. Maximum side-effects, actuarial incidence rate and prevalence rates, initial appearance and duration of ⩾grade 2 toxicity were evaluated. Results: Median follow-up was 74months. Late GI/GU side-effects ⩾grade 2 were detected in 15% (27/178) and 22% (40/178). The corresponding 5-year actuarial incidence rates for GI/GU side-effects were 19% and 23%, whereas the prevalence was 1–2% and 2–7% after 5years, respectively. Late side effects ⩾grade 2 appeared within 5years after radiotherapy in all patients with GI side-effects (27/27) and in 85% (34/40) of the patients with GU side-effects, respectively and lasted for less than 3years in 90% (GI) and 98% (GU). Conclusions: This study demonstrates that the majority of late GI and GU side effects after primary external beam radiotherapy for prostate cancer are transient. Using only actuarial incidence rates for reporting side effects may lead to misinterpretation or overestimation. The combination of incidence and prevalence rates provides a more comprehensive view on the complex issue of late side effects. [Copyright &y& Elsevier]

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]

• 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]

• 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.

• 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]

• 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: Purpose: Aim of this analysis was to compare biochemical no evidence of disease (bNED) rates in intermediate-risk prostate-cancer patients treated at two centres of excellence using different approaches: permanent interstitial brachytherapy (BT) and external beam radiotherapy (EBRT). Materials and methods: A total of 890 intermediate-risk prostate-cancer patients, who were treated from 1998 to 2008, were identified in the two local databases. In Utrecht 601 patients received I-125 BT applying a dose of 144Gy. In Vienna 289 patients were treated by EBRT, applying a local dose of 70Gy in 105 patients and 74Gy in 184 patients. bNED-rates (Phoenix-definition) were assessed. Results: Median follow-up was 48months (1–150). 5-Year actuarial bNED-rates were 81% for BT-patients and 75% for EBRT-patients (67% for 70Gy and 82% for 74Gy), respectively. In univariate analysis no difference between BT and EBRT could be detected. In multivariate analysis including tumour-stage, GleasonScore, initial PSA, hormonal therapy and treatment-centre (BT vs. EBRT) only T-stage, GleasonScore and PSA were found to be significant. Additional analysis including radiation dose showed the same outcome. Conclusions: Intermediate-risk prostate cancer patients treated by permanent interstitial brachytherapy show biochemical tumour-control-rates which are comparable to EBRT of 74Gy.

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]
