Abstract
BACKGROUND Several randomised, phase 3 trials have investigated the value of different techniques of accelerated partial breast irradiation (APBI) for patients with early breast cancer after breast-conserving surgery compared with whole-breast irradiation. In a phase 3 randomised trial, we evaluated whether APBI using multicatheter brachytherapy is non-inferior compared with whole-breast irradiation. Here, we present the 10-year follow-up results. METHODS We did a randomised, phase 3, non-inferiority trial at 16 hospitals and medical centres in Austria, Czech Republic, Germany, Hungary, Poland, Spain, and Switzerland. Patients aged 40 years or older with early invasive breast cancer or ductal carcinoma in situ treated with breast-conserving surgery were centrally randomly assigned (1:1) to receive either whole-breast irradiation or APBI using multicatheter brachytherapy. Whole-breast irradiation was delivered in 25 daily fractions of 50 Gy over 5 weeks, with a supplemental boost of 10 Gy to the tumour bed, and APBI was delivered as 30·1 Gy (seven fractions) and 32·0 Gy (eight fractions) of high-dose-rate brachytherapy in 5 days or as 50 Gy of pulsed-dose-rate brachytherapy over 5 treatment days. Neither patients nor investigators were masked to treatment allocation. The primary endpoint was ipsilateral local recurrence, analysed in the as-treated population; the non-inferiority margin for the recurrence rate difference (defined for 5-year results) was 3 percentage points. The trial is registered with ClinicalTrials.gov, NCT00402519; the trial is complete. FINDINGS Between April 20, 2004, and July 30, 2009, 1328 female patients were randomly assigned to whole breast irradiation (n=673) or APBI (n=655), of whom 551 in the whole-breast irradiation group and 633 in the APBI group were eligible for analysis. At a median follow-up of 10·36 years (IQR 9·12-11·28), the 10-year local recurrence rates were 1·58% (95% CI 0·37 to 2·8) in the whole-breast irradiation group and 3·51% (1·99 to 5·03) in the APBI group. The difference in 10-year rates between the groups was 1·93% (95% CI -0·018 to 3·87; p=0·074). Adverse events were mostly grade 1 and 2, in 234 (60%) of 393 participants in the whole-breast irradiation group and 314 (67%) of 470 participants in the APBI group, at 7·5-year or 10-year follow-up, or both. Patients in the APBI group had a significantly lower incidence of treatment-related grade 3 late side-effects than those in the whole-breast irradiation group (17 [4%] of 393 for whole-breast irradiation vs seven [1%] of 470 for APBI; p=0·021; at 7·5-year or 10-year follow-up, or both). At 10 years, the most common type of grade 3 adverse event in both treatment groups was fibrosis (six [2%] of 313 patients for whole-breast irradiation and three [1%] of 375 patients for APBI, p=0·56). No grade 4 adverse events or treatment-related deaths have been observed. INTERPRETATION Postoperative APBI using multicatheter brachytherapy after breast-conserving surgery in patients with early breast cancer is a valuable alternative to whole-breast irradiation in terms of treatment efficacy and is associated with fewer late side-effects.

Abstract
INTRODUCTION Clipping and selective removal of axillary lymph nodes in breast cancer patients presenting with initially node-positive disease and achieving a nodal downstaging after primary systemic therapy is a less invasive method for axillary staging. An imaging guided localization and successful extirpation of these clipped lymph nodes is not possible in all patients. To date no follow-up data regarding patients with lost clips are available. MATERIAL AND METHODS The oncological outcome of all participants of the CLIP-study and the results of postoperative axillary imaging in those patients with unproven clip resection are presented. RESULTS A total of thirty patients were included into the pilot study. In ten of these patients (33%) the removal of the clipped axillary lymph node could not be verified by intraoperative radiograph. Postoperative imaging did not find lost clips in eight of these ten patients (80%). The lost clip was detected in two patients after surgery (20%), by mammography in one patient during routine follow-up and by computed tomography scan in one patient before radiotherapy. After a median follow-up of 40 months, 26 (87%) patients were still alive. Seven patients (23%) developed distant recurrent disease. No local or axillary recurrences were observed. CONCLUSION Lost clips were detected by postoperative imaging only in a minority of patients. The impact of lost clips on axillary recurrences in breast cancer patients is still unclear and should be further clarified in larger, multicentric trials.

Abstract
BACKGROUND Previous results from the GEC-ESTRO trial showed that accelerated partial breast irradiation (APBI) using multicatheter brachytherapy in the treatment of early breast cancer after breast-conserving surgery was non-inferior to whole-breast irradiation in terms of local control and overall survival. Here, we present 5-year results of patient-reported quality of life. METHODS We did this randomised controlled phase 3 trial at 16 hospitals and medical centres in seven European countries. Patients aged 40 years or older with 0-IIA breast cancer were randomly assigned (1:1) after breast-conserving surgery (resection margins ≥2 mm) to receive either whole-breast irradiation of 50 Gy with a boost of 10 Gy or APBI using multicatheter brachytherapy. Randomisation was stratified by study centre, tumour type, and menopausal status, with a block size of ten and an automated dynamic algorithm. There was no masking of patients or investigators. The primary endpoint of the trial was ipsilateral local recurrence. Here, we present 5-year results of quality of life (a prespecified secondary endpoint). Quality-of-life questionnaires (European Organisation for Research and Treatment of Cancer QLQ-C30, breast cancer module QLQ-BR23) were completed before radiotherapy (baseline 1), immediately after radiotherapy (baseline 2), and during follow-up. We analysed the data according to treatment received (as-treated population). Recruitment was completed in 2009, and long-term follow-up is continuing. The trial is registered at ClinicalTrials.gov, number NCT00402519. FINDINGS Between April 20, 2004, and July 30, 2009, 633 patients had accelerated partial breast irradiation and 551 patients had whole-breast irradiation. Quality-of-life questionnaires at baseline 1 were available for 334 (53%) of 663 patients in the APBI group and 314 (57%) of 551 patients in the whole-breast irradiation group; the response rate was similar during follow-up. Global health status (range 0-100) was stable in both groups: at baseline 1, APBI group mean score 65·5 (SD 20·6) versus whole-breast irradiation group 64·6 (19·6), p=0·37; at 5 years, APBI group 66·2 (22·2) versus whole-breast irradiation group 66·0 (21·8), p=0·94. The only moderate, significant difference (difference of 10-20 points) between the groups was found in the breast symptoms scale. Breast symptom scores were significantly higher (ie, worse) after whole-breast irradiation than after APBI at baseline 2 (difference of means 13·6, 95% CI 9·7-17·5; p<0·0001) and at 3-month follow-up (difference of means 12·7, 95% CI 9·8-15·6; p<0·0001). INTERPRETATION APBI with multicatheter brachytherapy was not associated with worse quality of life compared with whole-breast irradiation. This finding supports APBI as an alternative treatment option after breast-conserving surgery for patients with early breast cancer. FUNDING German Cancer Aid.

Abstract
BACKGROUND We previously confirmed the non-inferiority of accelerated partial breast irradiation (APBI) with interstitial brachytherapy in terms of local control and overall survival compared with whole-breast irradiation for patients with early-stage breast cancer who underwent breast-conserving surgery in a phase 3 randomised trial. Here, we present the 5-year late side-effects and cosmetic results of the trial. METHODS We did this randomised, controlled, phase 3 trial at 16 centres in seven European countries. Women aged 40 years or older with stage 0-IIA breast cancer who underwent breast-conserving surgery with microscopically clear resection margins of at least 2 mm were randomly assigned 1:1, via an online interface, to receive either whole-breast irradiation of 50 Gy with a tumour-bed boost of 10 Gy or APBI with interstitial brachytherapy. Randomisation was stratified by study centre, menopausal status, and tumour type (invasive carcinoma vs ductal carcinoma in situ), with a block size of ten, according to an automated dynamic algorithm. Patients and investigators were not masked to treatment allocation. The primary endpoint of our initial analysis was ipsilateral local recurrence; here, we report the secondary endpoints of late side-effects and cosmesis. We analysed physician-scored late toxicities and patient-scored and physician-scored cosmetic results from the date of breast-conserving surgery to the date of onset of event. Analysis was done according to treatment received (as-treated population). This trial is registered with ClinicalTrials.gov, number NCT00402519. FINDINGS Between April 20, 2004, and July 30, 2009, we randomly assigned 1328 women to receive either whole-breast irradiation (n=673) or APBI with interstitial brachytherapy (n=655); 1184 patients comprised the as-treated population (551 in the whole-breast irradiation group and 633 in the APBI group). At a median follow-up of 6·6 years (IQR 5·8-7·6), no patients had any grade 4 toxities, and three (<1%) of 484 patients in the APBI group and seven (2%) of 393 in the whole-breast irradiation group had grade 3 late skin toxicity (p=0·16). No patients in the APBI group and two (<1%) in the whole-breast irradiation group developed grade 3 late subcutaneous tissue toxicity (p=0·10). The cumulative incidence of any late side-effect of grade 2 or worse at 5 years was 27·0% (95% CI 23·0-30·9) in the whole-breast irradiation group versus 23·3% (19·9-26·8) in the APBI group (p=0·12). The cumulative incidence of grade 2-3 late skin toxicity at 5 years was 10·7% (95% CI 8·0-13·4) in the whole-breast irradiation group versus 6·9% (4·8-9·0) in the APBI group (difference -3·8%, 95% CI -7·2 to 0·4; p=0·020). The cumulative risk of grade 2-3 late subcutaneous tissue side-effects at 5 years was 9·7% (95% CI 7·1-12·3) in the whole-breast irradiation group versus 12·0% (9·4-14·7) in the APBI group (difference 2·4%; 95% CI -1·4 to 6·1; p=0·28). The cumulative incidence of grade 2-3 breast pain was 11·9% (95% CI 9·0-14·7) after whole-breast irradiation versus 8·4% (6·1-10·6) after APBI (difference -3·5%; 95% CI -7·1 to 0·1; p=0·074). At 5 years' follow-up, according to the patients' view, 413 (91%) of 454 patients had excellent to good cosmetic results in the whole-breast irradiation group versus 498 (92%) of 541 patients in the APBI group (p=0·62); when judged by the physicians, 408 (90%) of 454 patients and 503 (93%) of 542 patients, respectively, had excellent to good cosmetic results (p=0·12). No treatment-related deaths occurred, but six (15%) of 41 patients (three in each group) died from breast cancer, and 35 (85%) deaths (21 in the whole-breast irradiation group and 14 in the APBI group) were unrelated. INTERPRETATION 5-year toxicity profiles and cosmetic results were similar in patients treated with breast-conserving surgery followed by either APBI with interstitial brachytherapy or conventional whole-breast irradiation, with significantly fewer grade 2-3 late skin side-effects after APBI with interstitial brachytherapy. These findings provide further clinical evidence for the routine use of interstitial multicatheter brachytherapy-based APBI in the treatment of patients with low-risk breast cancer who opt for breast conservation.

Abstract
BACKGROUND AND PURPOSE To compare early side effects and patient compliance of accelerated partial breast irradiation (APBI) with multicatheter brachytherapy to external beam whole breast irradiation (WBI) in a low-risk group of patients with breast cancer. MATERIAL AND METHODS Between April 2004 and July 2009, 1328 patients with UICC stage 0-IIA breast cancer were randomized to receive WBI with 50Gy and a boost of 10Gy or APBI with either 32.0Gy/8 fractions, or 30.1Gy/7 fractions (HDR-brachytherapy), or 50Gy/0.60-0.80Gy per pulse (PDR-brachytherapy). This report focuses on early side-effects and patient compliance observed in 1186 analyzable patients. ClinicalTrials.gov identifier: NCT00402519. RESULTS Patient compliance was excellent in both arms. Both WBI and APBI were well tolerated with moderate early side-effects. No grade 4 toxicity had been observed. Grade 3 side effects were exclusively seen for early skin toxicity (radiation dermatitis) with 7% vs. 0.2% (p<0.0001), and breast infection with 0% vs. 0.2% (p=n.s.) for patients treated with WBI and APBI. The incidence of grades 1-2 early side effects for WBI and APBI was 86% vs. 21% (p<0.0001) for skin toxicity, 2% vs. 20% (p<0.0001) for mild hematoma, and 2% vs. 5% (p=0.01) for mild breast infection rates, respectively. No differences had been found regarding grades 1-2 early breast pain (26% vs. 29%, p=0.23). CONCLUSIONS APBI with interstitial multicatheter brachytherapy was tolerated very well and dramatically reduced early skin toxicity in comparison to standard WBI.

Abstract
BACKGROUND In a phase 3, randomised, non-inferiority trial, accelerated partial breast irradiation (APBI) for patients with stage 0, I, and IIA breast cancer who underwent breast-conserving treatment was compared with whole-breast irradiation. Here, we present 5-year follow-up results. METHODS We did a phase 3, randomised, non-inferiority trial at 16 hospitals and medical centres in seven European countries. 1184 patients with low-risk invasive and ductal carcinoma in situ treated with breast-conserving surgery were centrally randomised to either whole-breast irradiation or APBI using multicatheter brachytherapy. The primary endpoint was local recurrence. Analysis was done according to treatment received. This trial is registered with ClinicalTrials.gov, number NCT00402519. FINDINGS Between April 20, 2004, and July 30, 2009, 551 patients had whole-breast irradiation with tumour-bed boost and 633 patients received APBI using interstitial multicatheter brachytherapy. At 5-year follow-up, nine patients treated with APBI and five patients receiving whole-breast irradiation had a local recurrence; the cumulative incidence of local recurrence was 1.44% (95% CI 0.51-2.38) with APBI and 0.92% (0.12-1.73) with whole-breast irradiation (difference 0.52%, 95% CI -0.72 to 1.75; p=0.42). No grade 4 late side-effects were reported. The 5-year risk of grade 2-3 late side-effects to the skin was 3.2% with APBI versus 5.7% with whole-breast irradiation (p=0.08), and 5-year risk of grade 2-3 subcutaneous tissue late side-effects was 7.6% versus 6.3% (p=0.53). The risk of severe (grade 3) fibrosis at 5 years was 0.2% with whole-breast irradiation and 0% with APBI (p=0.46). INTERPRETATION The difference between treatments was below the relevance margin of 3 percentage points. Therefore, adjuvant APBI using multicatheter brachytherapy after breast-conserving surgery in patients with early breast cancer is not inferior to adjuvant whole-breast irradiation with respect to 5-year local control, disease-free survival, and overall survival.

Abstract
The aim of the present study was to investigate the incidence of Candida stomatitis and resulting interruptions in radiation and radiochemotherapy in 50 patients suffering from squamous cell carcinomas of the head and neck region receiving fluconazole (100 mg d-1) in comparison with a historical control group (n = 50) without specific prophylaxis. Twenty of the control patients (40%) demonstrated Candida stomatitis, with seven of them (14%) requiring interruptions in anticancer therapy. In contrast, none of the patients with fluconazole had evidence of Candida stomatitis (P = 0.0000051) and subsequent interruption of anti-cancer therapy (P = 0.0061). Laboratory monitoring for the presence of Candida species was performed in 30 patients before and after therapy with fluconazole. Candida albicans was identified less frequently after therapy when compared with the pretreatment status. However, C. glabrata and C. krusei were isolated in some of the patients, probably because of drug resistance of these subspecies. The results demonstrate the clinical usefulness of prophylactic fluconazole applications in patients suffering from head and neck tumours with the aim of reducing Candida stomatitis and the resulting interruptions in radiation and radiochemotherapy.

Candida albicans was identified less frequently after therapy when compared to the pretreatment status. However, C. glabrata and C. krusei were isolated in some of the patients probably due to decreased drug susceptibility of these species.

Abstract
BACKGROUND The amount of radiation dose applied in the treatment of Hodgkin's disease is associated with the incidence of complications including radiation-induced pneumonitis, lung fibrosis and pericarditis. Therefore, from the beginning of 1986, we have started to apply a radiation therapy approach with reduced doses in order to minimize complications while maintaining effective treatment. PATIENTS AND METHOD From 1983 through 1992 141 patients suffering from Hodgkin's disease were included in the present study. All of them were treated by radiation of mediastinum. In 126 cases polychemotherapy was applied before radiation. From 1986 we used a reduced radiation dose in cases that were treated by radiation alone (affected nodal regions with 40 Gy instead of 45 Gy and unaffected nodal regions with 36 Gy instead of 40 Gy) as well as after application of chemotherapy (affected nodal regions 36 Gy instead of 40 Gy and unaffected nodal regions with 30 Gy instead of 36 Gy). Ninety-five patients were treated according to the new therapy protocol. Forty-six patients had been treated with the higher dosages and served as the historical control group. Radiation therapy included Co-60, 15-MV and 9-MV photons, and 15-MeV and 9-MeV electrons. Serial thoracic X-ray controls were performed. CT scans, echocardiographic and electrocardiographic investigations were added in selected cases. RESULTS During the period from 1983 to 1992, we diagnosed radiation-induced pneumonitis in 31% of the patients who underwent radiation therapy of the mediastinum. In addition, 16% demonstrated lung fibrosis and 10% pericarditis. After implementation of the reduced radiation dosages, the incidence of pneumonitis decreased from 35% to 24% (nearly significant in the 5% range), lung fibrosis from 24% to 12% (p < 0.05) and pericarditis from 26% to 2% (p < 0.01). The efficacy of treatment remained unaffected by the new therapy approach as has been demonstrated for cumulative survival data and recurrence-free intervals. CONCLUSIONS Reduction of radiation dose in patients with Hodgkin's disease who undergo mediastinal radiation leads to a decrease in the incidence of radiation-induced complications (pneumonitis, lung fibrosis, pericarditis) whereas treatment efficacy remains unchanged.
