Fernando IN, Lax S, Bowden SJ, Ahmed I, Steven JH, Churn M, Brunt AM, Agrawal RK, Canney P, Stevens A, Rea DW. Detailed Sub-study Analysis of the SECRAB Trial: Quality of Life, Cosmesis and Chemotherapy Dose Intensity. Clin Oncol (R Coll Radiol) 2023; 35:397-407. [PMID: 37012180 PMCID: PMC10186116 DOI: 10.1016/j.clon.2023.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 02/03/2023] [Accepted: 03/10/2023] [Indexed: 04/03/2023]
Abstract
AIMS SECRAB was a prospective, open-label, multicentre, randomised phase III trial comparing synchronous to sequential chemoradiotherapy (CRT). Conducted in 48 UK centres, it recruited 2297 patients (1150 synchronous and 1146 sequential) between 2 July 1998 and 25 March 2004. SECRAB reported a positive therapeutic benefit of using adjuvant synchronous CRT in the management of breast cancer; 10-year local recurrence rates reduced from 7.1% to 4.6% (P = 0.012). The greatest benefit was seen in patients treated with anthracycline-cyclophosphamide, methotrexate, 5-fluorouracil (CMF) rather than CMF. The aim of its sub-studies reported here was to assess whether quality of life (QoL), cosmesis or chemotherapy dose intensity differed between the two CRT regimens. MATERIALS AND METHODS The QoL sub-study used EORTC QLQ-C30, EORTC QLQ-BR23 and the Women's Health Questionnaire. Cosmesis was assessed: (i) by the treating clinician, (ii) by a validated independent consensus scoring method and (iii) from the patients' perspective by analysing four cosmesis-related QoL questions within the QLQ-BR23. Chemotherapy doses were captured from pharmacy records. The sub-studies were not formally powered; rather, the aim was that at least 300 patients (150 in each arm) were recruited and differences in QoL, cosmesis and dose intensity of chemotherapy assessed. The analysis, therefore, is exploratory in nature. RESULTS No differences were observed in the change from baseline in QoL between the two arms assessed up to 2 years post-surgery (Global Health Status: -0.05; 95% confidence interval -2.16, 2.06; P = 0.963). No differences in cosmesis were observed (via independent and patient assessment) up to 5 years post-surgery. The percentage of patients receiving the optimal course-delivered dose intensity (≥85%) was not significantly different between the arms (synchronous 88% versus sequential 90%; P = 0.503). CONCLUSIONS Synchronous CRT is tolerable, deliverable and significantly more effective than sequential, with no serious disadvantages identified when assessing 2-year QoL or 5-year cosmetic differences.

Effect of radiotherapy sequence on long-term outcome in patients with node-positive breast cancer: a retrospective study. Sci Rep 2022; 12:10729. [PMID: 35750892 PMCID: PMC9232535 DOI: 10.1038/s41598-022-14873-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 03/10/2022] [Indexed: 11/26/2022] Open
Abstract
The optimal sequence of chemotherapy (CT) and radiotherapy (RT) after surgery in breast cancer patients is unclear. There is a lack of literature on RT given between anthracycline and taxane administration. We evaluated the effect of RT sequence on long-term outcome in breast cancer. Two hundred patients who underwent surgery between January 2009 and December 2012 for node-positive breast cancers were evaluated retrospectively. All patients were treated with doxorubicin and cyclophosphamide (AC) followed by taxane. Sandwich RT group that received RT between AC and taxane was compared to the group that received RT after CT. The mean follow-up period was 105.4 months. The locoregional recurrence (LRR) rate was lower in sandwich RT group (P = 0.012) and there was no significant difference in distant metastasis between the two groups. The RT sequence was an important predictor for LRR in multivariable analysis (P = 0.017). For luminal A subtype, disease-free survival (DFS) was better in sandwich RT group than in CT followed by RT group (P = 0.001). The overall survival did not correlated with RT sequence regardless of subtype. Sandwich RT can offer DFS benefit in luminal A subtype breast cancer. A tailored approach of sequencing chemotherapy and radiotherapy would be needed considering the factors that can influence outcome.

Assessment of planning reproducibility in three-dimensional field-in-field radiotherapy technique for breast cancer: impact of surgery-simulation interval. Sci Rep 2021; 11:1556. [PMID: 33452292 PMCID: PMC7810888 DOI: 10.1038/s41598-020-78666-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Accepted: 10/21/2020] [Indexed: 11/16/2022] Open
Abstract
The three-dimensional field-in-field (3-D FIF) technique for radiotherapy is an advanced, state-of-the-art method that uses multileaf collimators to generate a homogeneous and conformal dose distribution via segmental subfields. The purpose of this study is to evaluate the dosimetric reproducibility of 3-D FIF plans using the original simulation computed tomography (iCT) scans and re-simulation CT (rCT) scans for whole breast irradiation (WBI) schedule. This study enrolled a total of 34 patients. The study population underwent iCT scans for standard WBI and took rCT scans after 45 Gy of WBI for cone down boost plans. The dosimetric parameters (V105%, V103%, V100%, V98%, V95%, V90%, V50%), plan quality indices (conformity index, homogeneity index) and clinical parameters (isocenter-breast axis, isocenter-lung axis, soft tissue volumes within radiation field, lung volumes within radiation field) were assessed. The median time interval from surgery to iCT was 33 days and from iCT to rCT was 35 days. All dosimetric parameters exhibited statistically significant differences between iCT and rCT among cohorts with a surgery-iCT interval of < 60 days. Homogeneity index showed a statistically significant increase from iCT to rCT among all cohorts. Soft tissue volumes (p = 0.001) and isocenter-breast axis (p = 0.032) exhibited statistically significant differences among cohorts with surgery-iCT interval < 60 days. Regarding the reproducibility of the 3-D FIF WBI plans, significant changes were observed in dosimetric and clinical factors, particularly in study cohorts with a surgery-simulation interval < 60 days. The main contributing factor of these transitions seemed to be the changes in volume of the soft tissue within the WBI field. Further confirmative studies are necessary to determine the most suitable timing and technique for WBI.

Abstract
The majority of advanced cancer patients suffer from pain, which severely deteriorates their quality of life. Apart from analgesics, bisphosphonates, and invasive methods of analgesic treatment (e.g., intraspinal and epidural analgesics or neurolytic blockades), radiation therapy plays an important role in pain alleviation. It is delivered to a growing primary tumour, lymph nodes, or distant metastatic sites, producing pain of various intensity. Currently, different regiments of radiation therapy methods and techniques and various radiation dose fractionations are incorporated into the clinical practice. These include palliative radiation therapy, conventional external beam radiation therapy, as well as modern techniques of intensity modulated radiation therapy, volumetrically modulated arch therapy, stereotactic radiosurgery or stereotactic body radiation therapy, and brachytherapy or radionuclide treatment (e.g., radium-223, strontium-89 for multiple painful osseous metastases). The review describes the possibilities and effectiveness of individual patient-tailored conventional and innovative radiation therapy approaches aiming at pain relief in cancer patients.

Abstract
Aims and background To compare the outcome of concurrent versus sequential administration of cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) chemotherapy and radiotherapy after breast-conserving surgery in early breast cancer. Methods From February 1992 to January 2002, 156 patients underwent CMF chemotherapy and radiotherapy, either concurrently (CCRT group, 88 patients) or sequentially (SCRT group, 68 patients). There was a predilection of patients with a larger tumor (P = 0.0035), with more frequent nodal involvement (P = 0.0686), and younger age (P = 0.0776) in the CCRT group. Results The planned radiotherapy was completed in every patient. No grade 3 or 4 late treatment-related toxicity was observed in the CCRT or SCRT group. Compliance to the treatment as well as cosmetic outcome of the two groups were comparable. Despite more adverse factors for local-regional recurrence in the CCRT group, the 5-year local-regional control rate of the CCRT group was similar to that of the SCRT group (97.7% vs 93.8%, respectively, P = 0.1688). On multivariate analysis, concomitant administration of chemotherapy and radiotherapy was associated with improved local-regional control (P = 0.0463). Conclusions Concurrent administration of CMF chemotherapy and radiotherapy resulted in improved local-regional control over sequential administration without an increase in significant toxicity. Concurrent CMF chemoradiotherapy may serve as a viable option for patients at high-risk of local-regional relapse not suitable for anthracycline or taxane-based chemotherapy.

Abstract
Aims and Background The aim of surveys on clinical practice is to stimulate discussion and optimize practice. In this paper the current Italian radiotherapy practice after breast-conserving surgery for early breast cancer is described and adherence to national and international guidelines is assessed. Furthermore, results are compared with an earlier survey in northern Italy and international reports. Study Design A multiple-choice questionnaire sent to all 138 Italian radiation oncology centers. Results 48% of centers responded. Most performed breast-conserving surgery when tumor size was ≤3 cm. All centers routinely performed axillary dissection; 45 carried out sentinel node biopsy followed by axillary dissection when the sentinel node was positive. Most centers re-excised when resection margins were positive. The median interval between surgery and radiotherapy, when chemotherapy was not administered, was 60 days. Adjuvant chemotherapy was preferably administered before radiotherapy. Regional lymph nodes were never irradiated in 10 centers; in all others irradiation depended on the number of positive lymph nodes and/or involvement of axillary fat and/or tumor location in medial quadrants. All centers used standard fractionation; hypofractionated schemes were available in 6. Most centers used 4–6 MV photons. In 59 centers the boost dose of 10 Gy could be increased if margins were not negative. All centers ensured patient setup reproducibility. Treatment planning was computerized in 59 centers. The irradiation dose was prescribed at the ICRU point in 56 centers and portal films were made in 54 centers. Intraoperative radiotherapy was used in 4 centers: for partial breast irradiation in 1 and for boost administration in 3 centers. Conclusions Although the quality of radiotherapy delivery has improved in Italy in recent years, approaches that do not conform to international standards persist.

Abstract
BACKGROUND Concurrent chemoradiotherapy could increase the local control rate in patients with high recurrence risk after breast-conserving surgery, but the effect of concurrent chemoradiotherapy after mastectomy and axillary dissection is not clear. The aim of the study was to compare the effects of late-course concurrent chemoradiotherapy (CCRT) versus sequential therapy (SCRT) after mastectomy and axillary surgery in locally advanced breast cancer. METHODS This was a randomized controlled trial of 155 patients with stage pT3-4p N1-3c M0 or pAnyT pN2-3c M0 breast cancer undergoing 5-fluorouracil+epirubicin+cyclophosphamide followed by docetaxel (FEC-D) chemotherapy after mastectomy and axillary dissection. Patients were randomized to the CCRT group (intensity-modulated radiation therapy was performed concurrently with docetaxel) or to the SCRT group (radiotherapy after chemotherapy). Recurrences, adverse reactions, and short-term effects were observed. RESULTS All the patients completed the planned therapy. The median follow-up was 39 (range, 16-62) months. Compared with SCRT, the 3-year local-regional recurrence-free survival (LRFS) in the CCRT group was improved (81.8% vs 92.3%, P = .046). There was no significant difference in 3-year disease-free survival (DFS) and overall survival (OS). In the pT3-4 pN1-3 cM0 subgroup, the 3-year local recurrence-free survival and DFS were significantly improved in the CCRT group (69.4% vs 88.2%, P = .036; and 41.7% vs 72.6%, P = .049, respectively). No significant difference was observed adverse reactions between the 2 groups. CONCLUSION LRFS of patients with locally advanced invasive breast cancer after mastectomy and axillary surgery was better with CCRT than with SCRT and with similar profiles of adverse reactions. The DFS of patients staged pT3-4 pN1-3 cM0 was also improved.

Abstract
BACKGROUND Tests of tumour treatment time effect in patients prescribed post-operative radiotherapy for early breast cancer have focussed on time to start of radiotherapy rather than overall treatment time. The START randomised trials of radiotherapy fractionation provide an opportunity to directly estimate the effect of treatment acceleration. METHODS Between 1986 and 2002, a total of 5861 women with early breast cancer were recruited into the UK START pilot (START-P), START-A and START-B randomised trials. START-P and START-A tested 13 fractions of 3.0-3.3Gy against 25 fractions of 2.0Gy with a fixed treatment duration of 5weeks for all schedules; START-B tested 15 fractions of 2.67Gy in 3weeks against 25 fractions of 2.0Gy over 5weeks. Estimates of the effect of length of treatment for local-regional relapse and for a measure of late normal tissue effects (change in photographic breast appearance, for patients following breast conserving surgery) were obtained from Cox proportional hazards regression analyses stratified according to trial. RESULTS At a median follow-up of 10years, 444/5831 (7.6%) patients with data available had a local-regional relapse, and 1135/3185 (35.6%) had mild or marked change in photographic breast appearance by 5years. Adjusting for prognostic factors, the estimate of the overall treatment time effect for local-regional relapse was 0.60Gy/day (95%CI 0.10 to 1.18Gy/day, p=0.02), and 0.14Gy/day (95%CI -0.09 to 0.34Gy/day, p=0.29) for change in photographic breast appearance. CONCLUSIONS Combined analysis of the START trials generates the hypothesis that overall treatment time is a significant determinant of local cancer control after adjuvant whole breast radiotherapy, with approximately 0.6Gy per day 'wasted' in compensating for tumour cell proliferation.

Abstract
OBJECTIVE After breast conservative surgery (BCS) and whole-breast radiotherapy (WBRT), the use of boost irradiation is recommended especially in patients at high risk. However, the standard technique and the definition of the boost volume have not been well defined. METHODS We retrospectively compared an anticipated pre-operative photon boost on the tumour, administered with low-dose fractionated radiotherapy, and neoadjuvant chemotherapy with two different sequential boost techniques, administered after BCS and standard adjuvant WBRT: (1) a standard photon beam (2) and an electron beam technique on the tumour bed of the same patients. The plans were analyzed for the dosimetric coverage of the CT-delineated irradiated volume. The minimal dose received by 95% of the target volume (D95), the minimal dose received by 90% of the target volume (D90) and geographic misses were evaluated. RESULTS 15 patients were evaluated. The sequential photon and electron boost techniques resulted in inferior target volume coverage compared with the anticipated boost technique, with a median D95 of 96.3% (range 94.7-99.6%) and 0.8% (range 0-30%) and a median D90 of 99.1% (range 90.2-100%) and 54.7% (range 0-84.8%), respectively. We observed a geographic miss in 26.6% of sequential electron plans. The results of the anticipated boost technique were better: 99.4% (range 96.5-100%) and 97.1% (range 86.2-99%) for median D90 and median D95, respectively, and no geographic miss was observed. We observed a dose reduction to the heart, with left-sided breast irradiation, using the anticipated pre-operative boost technique, when analyzed for all dose-volume parameters. When compared with the sequential electron plans, the pre-operative photon technique showed a higher median ipsilateral lung Dmax. CONCLUSION Our data show that an anticipated pre-operative photon boost results in a better coverage with respect to the standard sequential boost while also saving the organs at risk and consequently fewer side effects. ADVANCES IN KNOWLEDGE This is the first dosimetric study that evaluated the association between an anticipated boost and neoadjuvant chemotherapy treatment.

[PMID: 27209504 DOI: 10.1016/j.ijrobp.2016.03.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2015] [Revised: 03/07/2016] [Accepted: 03/11/2016] [Indexed: 01/08/2023]
Abstract
PURPOSE To compare long-term late local toxicity after either concomitant or sequential chemoradiation therapy after breast-conserving surgery. METHODS AND MATERIALS From 1997 to 2002, women aged 18 to 75 years who underwent breast-conserving surgery and axillary dissection for early breast cancer and in whom CMF (cyclophosphamide, methotrexate, and 5-fluorouracil) chemotherapy was planned were randomized between concomitant and sequential radiation therapy. Radiation therapy was delivered to the whole breast through tangential fields to 50 Gy in 20 fractions over a period of 4 weeks, followed by an electron boost. Surviving patients were tentatively contacted and examined between March and September 2014. Patients in whom progressive disease had developed or who had undergone further breast surgery were excluded. Local toxicity (fibrosis, telangiectasia, and breast atrophy or retraction) was scored blindly to the treatment received. A logistic regression was run to investigate the effect of treatment sequence after correction for several patient-, treatment-, and tumor-related covariates on selected endpoints. The median time to cross-sectional analysis was 15.7 years (range, 12.0-17.8 years). RESULTS Of 206 patients randomized, 154 (74.8%) were potentially eligible. Of these, 43 (27.9%) refused participation and 4 (2.6%) had been lost to follow-up, and for 5 (3.2%), we could not restore planning data; thus, the final number of analyzed patients was 102. No grade 4 toxicity had been observed, whereas the number of grade 3 toxicity events was low (<8%) for each item, allowing pooling of grade 2 and 3 events for further analysis. Treatment sequence (concomitant vs sequential) was an independent predictor of grade 2 or 3 fibrosis according to both the National Cancer Institute Common Terminology Criteria for Adverse Events (odds ratio [OR], 4.05; 95% confidence interval [CI], 1.34-12.2; P=.013) and the SOMA (Subjective, Objective, Management and Analytic) scale (OR, 3.75; 95% CI, 1.19-11.79; P=.018), as well as grade 2 or 3 breast atrophy or retraction (OR, 3.87; 95% CI, 1.42-10.56; P=.008). No effect on telangiectasia was detected. CONCLUSIONS At long-term follow-up, concomitant chemoradiation therapy has a detrimental effect on both fibrosis and retraction with an approximately 4-fold increase in the odds of grade 2 or 3 toxicity.

Abstract
Introduction The clinical target volume (CTV) for early stage breast cancer is difficult to clearly identify on planning computed tomography (CT) scans. Surgical clips inserted around the tumour bed should help to identify the CTV, particularly if the seroma has been reabsorbed, and enable tracking of CTV changes over time. Methods A surgical clip-based CTV delineation protocol was introduced. CTV visibility and its post-operative shrinkage pattern were assessed. The subjects were 27 early stage breast cancer patients receiving post-operative radiotherapy alone and 15 receiving post-operative chemotherapy followed by radiotherapy. The radiotherapy alone (RT/alone) group received a CT scan at median 25 days post-operatively (CT1rt) and another at 40 Gy, median 68 days (CT2rt). The chemotherapy/RT group (chemo/RT) received a CT scan at median 18 days post-operatively (CT1ch), a planning CT scan at median 126 days (CT2ch), and another at 40 Gy (CT3ch). Results There was no significant difference (P = 0.08) between the initial mean CTV for each cohort. The RT/alone cohort showed significant CTV volume reduction of 38.4% (P = 0.01) at 40 Gy. The Chemo/RT cohort had significantly reduced volumes between CT1ch: median 54 cm3 (4–118) and CT2ch: median 16 cm3, (2–99), (P = 0.01), but no significant volume reduction thereafter. Conclusion Surgical clips enable localisation of the post-surgical seroma for radiotherapy targeting. Most seroma shrinkage occurs early, enabling CT treatment planning to take place at 7 weeks, which is within the 9 weeks recommended to limit disease recurrence.

Abstract
BACKGROUND In cases of locally advanced breast cancer (labc), preoperative ("neoadjuvant") therapy was traditionally reserved to render the patient operable. More recently, neoadjuvant therapy, particularly chemotherapy, is being used in patients with operable disease to increase the opportunity for breast conservation. Despite the increasing use of preoperative chemotherapy, rates of pathologic complete response, a surrogate marker for disease-free survival, remain modest in patients with locally advanced disease and particularly so when the tumour is estrogen or progesterone receptor-positive and her2-negative. A new paradigm for labc patients is needed. In other solid tumours (for example, rectal, esophageal, and lung cancers), concurrent chemoradiotherapy (ccrt) is routinely used in neoadjuvant and adjuvant treatment protocols alike. RESULTS The literature suggests that ccrt in labc patients with inoperable disease is associated with response rates higher than would be anticipated with systemic therapy alone. CONCLUSIONS Ongoing trials in this field are eagerly awaited to determine if ccrt should become the new paradigm.

Abstract
BACKGROUND After surgery for localised breast cancer, radiotherapy (RT) improves both local control and breast cancer-specific survival. In patients at risk of harbouring micro-metastatic disease, adjuvant chemotherapy (CT) improves 15-year survival. However, the best sequence of administering these two types of adjuvant therapy for early-stage breast cancer is unclear. OBJECTIVES To determine the effects of different sequencing of adjuvant CT and RT for women with early breast cancer. SEARCH METHODS An updated search was carried out in the Cochrane Breast Cancer Group's Specialised Register (20 May 2011), MEDLINE (14 December 2011), EMBASE (20 May 2011) and World Health Organization (WHO) International Clinical Trials Registry Platform (20 May 2011). Details of the search strategy and methods of coding for the Specialised Register are described in the Group's module in The Cochrane Library. We extracted studies that had been coded as 'early', 'chemotherapy' and 'radiotherapy'. SELECTION CRITERIA We included randomised controlled trials evaluating different sequencing of CT and RT. DATA COLLECTION AND ANALYSIS We assessed the eligibility and quality of the identified studies and extracted data from the published reports of the included trials. We derived odds ratios (OR) and hazard ratios (HR) from the available numerical data. Toxicity data were extracted, where reported. We used a fixed-effect model for meta-analysis and conducted analyses on the basis of the method of sequencing of the two treatments. MAIN RESULTS Three trials reporting two different sequencing comparisons were identified. There were no significant differences between the various methods of sequencing adjuvant therapy for local recurrence-free survival, overall survival, relapse-free survival and metastasis-free survival based on 1166 randomised women in three trials. Concurrent chemoradiation increased anaemia (OR 1.54; 95% confidence interval (CI) 1.10 to 2.15), telangiectasia (OR 3.85; 95% CI 1.37 to 10.87) and pigmentation (OR 15.96; 95% CI 2.06 to 123.68). Treated women did not report worse cosmesis with concurrent chemoradiation but physician-reported assessments did (OR 1.14; 95% CI 0.42 to 3.07). Other measures of toxicity did not differ between the two types of sequencing. On the basis of one trial (244 women), RT before CT was associated with an increased risk of neutropenic sepsis (OR 2.96; 95% CI 1.26 to 6.98) compared with CT before RT, but other measures of toxicity did not differ. AUTHORS' CONCLUSIONS The data included in this review, from three well-conducted randomised trials, suggest that different methods of sequencing CT and RT do not appear to have a major effect on recurrence or survival for women with breast cancer if RT is commenced within seven months after surgery.

Preoperative radio-chemotherapy in early breast cancer patients: long-term results of a phase II trial. Radiother Oncol 2011; 102:82-8. [PMID: 21907436 DOI: 10.1016/j.radonc.2011.08.017] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2010] [Revised: 08/10/2011] [Accepted: 08/20/2011] [Indexed: 11/12/2022]
Abstract
PURPOSE This phase II trial aimed to investigate the efficacy of concurrent radio- (RT) and chemotherapy (CT) in the preoperative setting for operable, non-metastatic breast cancer (BC) not amenable to initial breast-conserving surgery (BCS). PATIENTS AND METHODS From 2001 to 2003, 59 women were included. CT consisted of four cycles of 5-FU, 500 mg/m(2)/d, continuous infusion (d1-d5) and vinorelbine, 25 mg/m(2) (d1 and d6). Starting concurrently with the second cycle, RT delivered 50 Gy to the breast and 46 Gy to the internal mammary and supra/infra-clavicular areas. Breast surgery and lymph node dissection were then performed. Adjuvant treatment consisted of a 16 Gy boost to the tumor bed after BCS, FEC (four cycles of fluorouracil 500 mg/m(2), cyclophosphamide 500 mg/m(2), and epirubicin 100 mg/m(2), d1; d21) for pN1-3 and hormone-therapy for positive hormone receptors BC. RESULTS The in-breast pathological complete response rate was 27%. BCS was performed in 41 (69%) pts. Overall and distant-disease free survivals at 5 years were respectively 88% [95% CI 80-98] and 83% [95% CI 74-93] whereas locoregional and local controls were 90% [95% CI 82-97] and 97% [95% CI 92-100]. Late toxicity (CTCAE-V3) was assessed in 51 pts (86%) with a median follow-up of 7 years [5-8]. Four (8%) experienced at least one grade III toxicities (one telangectasia and three fibroses). Cosmetic results, assessed in 35 of the 41 pts (85%) who retained their breasts, were poor in four pts (11%). CONCLUSION Preoperative concurrent administration of RT and CT is an effective regimen. Long-term toxicity is moderate. This association deserves further evaluations in prospective trials.

Abstract
OBJECTIVE A prospective, phase III randomized study was undertaken to compare the outcomes of 2 different radiotherapy and chemotherapy sequences in conservatively treated patients with breast cancer. METHODS Between January 1997 and November 2002, 206 patients operated of quadrantectomy and axillary dissection for breast cancer, candidates to receive adjuvant CMF chemotherapy (cyclophosphamide, methotrexate, and fluorouracil) were assigned to concurrent or sequential radiation treatment by using a balanced randomization method. Before randomization patients were stratified by tumor diameter, age, and lymph node status. The primary end point was the freedom from breast recurrence, and secondary end points were overall and disease-free survival. Overall outcomes were analyzed according to the intention-to-treat principle. RESULTS All 206 patients enrolled and randomized in the trial were analyzed. The median follow-up was 111 months, with no patient lost for follow-up. No difference in 10-years breast recurrence-free, disease-free, metastasis-free, and overall survival rates was observed in the 2 treatment sequence groups. The Hazard Ratios, calculated for each prognostic factor, showed no difference in all outcomes between the 2 treatment sequences. CONCLUSIONS No influence of the treatment sequence on long-term outcomes was observed in this trial. This finding suggests that to avoid an increased risk of distant recurrence or an excessive toxicity, radiation therapy may be delayed until after the end of the more, recently used, anthracycline-based chemotherapy without increasing the risk of breast recurrences, thus allowing the delivery of full-dose chemotherapy in patients at risk for systemic disease spread.

Abstract
PURPOSE This study was done to evaluate the toxicity related to concurrent radiotherapy and anthracycline (AC)-based chemotherapy in the adjuvant treatment of early breast cancer and to investigate the impact of treatment interruptions and the feasibility of this uncommon therapeutic approach. MATERIALS AND METHODS From September 2002 to December 2007, 60 patients were treated at our Centre. The mean age at presentation was 48.5 (range 38-64) years. All patients underwent conservative surgery, and radiotherapy to the entire breast (mean dose 50 Gy; range 46-52 Gy). AC-based regimens consisted of four cycles of AC (doxorubicin plus cyclophosphamide) or four cycles of epirubicin (EPI) followed by four courses of cyclophosphamide, methotrexate and 5-fluorouracil (CMF). RESULTS Concomitant treatment caused acute skin G3 toxicity in 8.9% of patients and one case of G4 toxicity (1.7%). Concerning cardiac assessment, six of the 56 evaluable patients (10.7%) developed an asymptomatic decline of left ventricular ejection fraction >10% and <20% of the baseline value. Radiotherapy was temporarily stopped in 21.3% and chemotherapy in 57.1% of patients. CONCLUSIONS In our experience, concomitant chemotherapy did not emerge as a significant factor in radiotherapy interruption. Moreover, no severe cardiac events were recorded.

Abstract
Due to the significant advances in the diagnosis and treatment of breast cancer seen in the last decades, increased survival rates and better outcomes of patients are being observed. The role of radiotherapy remains pivotal in the treatment of early breast cancer. In the adjuvant setting, whole breast irradiation remains the standard of care using a relatively well standardized radiation technique. The recent technology advances and 3D conformal radiotherapy allow for better volumes definition resulting to increased organ at risk--sparing and therefore treatment optimization. Sophisticated techniques and emerging options (such as accelerated partial breast irradiation) are not routinely used yet outside of a clinical trial. Moreover, new drugs and targeted therapies have recently been introduced to the clinical practice for treatment individualization according to the specific tumours' prognosis and/or prediction of the drugs' efficacy based on new biological tools. Regarding the synergistic effect of these molecules with ionizing radiation, rigorous prospective evaluation of combined therapy is important to ensure improved long-term benefit/risk ratio. In this review, the significant advances of radiotherapy and combined therapy in the new era of breast cancer management will be discussed.

Abstract
Background Concurrent chemoradiotherapy (CCRT) after breast surgery was investigated by few authors and remains controversial, because of concerns of toxicity with taxanes/anthracyclines and radiation. This treatment is not standard and is more commonly used for locally advanced breast cancer. The aim of our study was to evaluate the efficacy and safety of the concomitant use of anthracycline with radiotherapy (RT). Findings Four hundred women having operable breast cancer, treated by adjuvant chemotherapy (CT) and RT in concomitant way between January 2001 and December 2003, were included in this retrospective cohort study. The study compares 2 adjuvant treatments using CCRT, the first with anthracycline (group A) and the second with CMF (group B). The CT treatment was repeated every 21 days for 6 courses and the total delivered dose of RT was 50 Gy, divided as 2 Gy daily fractions. Locoregional recurrence free (LRFS), event free (EFS), and overall survivals (OS) were estimated by the Kaplan-Meier method. The log-rank test was used to compare survival events. Multivariate Cox-regression was used to evaluate the relationship between patient characteristics, treatment and survival. In the 2 groups (A+B) (n = 400; 249 in group A and 151 in group B), the median follow-up period was 74.5 months. At 5 years, the isolated LRFS was significantly higher in group A compared to group B (98.7% vs 95.3%; hazard ratio [HR] = 0.258; 95% CI, 0.067 to 0.997; log-rank P = .034). In addition, the use of anthracycline regimens was associated with a higher rate of 5 years EFS (80.4% vs 75.1%; HR = 0.665; 95% CI, 0.455 to 1.016; log-rank P = .057). The 5 years OS was 83.2% and 79.2% in the anthracycline and CMF groups, respectively (HR = 0.708; 95% CI, 0.455 to 1.128; log-rank P = .143). Multivariate analysis confirmed the positive effect of anthracycline regimens on LRFS (HR = 0.347; 95% CI, 0.114 to 1.053; log-rank P = .062), EFS (HR = 0.539; 95% CI, 0.344 to 0.846; P = 0.012), and OS (HR = 0.63; 95% CI, 0.401 to 0.991; P = .046). LRFS, EFS and OS were significantly higher in the anthracycline group where the patients (n = 288) received more than 1 cycle of concurrent CT (P = .038, P = .026 and P = .038, respectively). LRFS and EFS were significantly higher in the anthracycline group within the BCT subgroup (P = .049 and P = .04, respectively). There were more hematologic, and more grade 2/3/4 skin toxicity in the anthracycline group. Conclusions After mastectomy or BCT, the adjuvant treatment based on anthracycline and concurrent RT reduced breast cancer relapse rate, and significantly improved LRFS, EFS and OS in the patients receiving more than 1 cycle of concurrent CT. There were more hematologic and non hematologic toxicities in the anthracycline group.

Abstract
PURPOSE While new strategies for the treatment of invasive breast cancer (BC) are emerging, radiotherapy (RT) modalities are still under debate. The French expert review board of Nice-Saint-Paul de Vence was asked firstly to conduct a qualitative evidence-based systematic review and then to establish clinical practice guidelines for the use of post operative RT in invasive BC. METHODS AND MATERIALS A search to identify eligible studies was undertaken using the Medline® database. All phase III randomized trials and systematic reviews evaluating the role and modalities of RT in invasive BC were included, together with some noncontrolled studies if no randomized trials were identified. The quality and clinical relevance of the studies were evaluated to determine the level of evidence. RESULTS The maximum delay between surgery and RT should ≤8 weeks when chemotherapy (CT) is not indicated. This should not exceed 24 weeks when adjuvant CT is administered. Whole breast RT delivering 50 Gy in 25 fractions followed by a boost of 10-16 Gy remains the standard of care after conservative surgery (CS). In the elderly population, for certain cases presenting comorbidities associated with a limited life expectancy, RT indication (even hypofractioned) and boost delivery may be unnecessary in the light of an unfavourable risk/benefit ratio. RT technique and indications should not vary in case of neoadjuvant CT followed by CS. After total mastectomy, RT should be indicated in N+ and in N- patients with high risk of local recurrence. The experts recommend to initiate tamoxifen at the end of RT, while aromatase inhibitors could be administered either concomitantly or sequentially with RT. There is no consistent data to delay (or suspend) trastuzumab administration during RT. As for all patients, in case of concurrent RT-trastuzumab administration, reduction of cardiac tissues exposure is highly recommended. After breast reconstruction, RT should be delivered as after standard CS without boost. CONCLUSION Due to significant variations in practice in the treatment of patients with BC, our group aimed to provide guidelines for clinical practice. The systematic review of the literature formed the basis of our evidence-based recommendations; however expert agreements were necessary on those subjects that are still under debate. Our group will update these guidelines every 4 years, taking in consideration new advances in technology, new drugs administration, biologic tools and innovative therapeutic options.

Abstract
The aim of the study is to report the long-term outcome and secondary tumours of early breast cancer patients of adjuvant CNF (cyclophosphamide, mitoxantrone, and 5-fluorouracil) chemotherapy. One hundred and ninety four patients, 185 primary early breast cancer and nine locoregionally recurrent breast cancer patients, were entered onto the trial between May 1986 and November 1993. The therapies included surgery, radiation therapy, adjuvant CNF chemotherapy, and tamoxifen according to hormonal status. Some of patients were treated twice with CMF (methotrexate). The median follow-up time was 12.9 years. Eighty nine (48%) primary breast cancers relapsed, and six locoregional breast cancers relapsed. After 5-10 years the relapse incidence decreased notably. Eighty three patients died of breast cancer, and nine of other causes. Two cases of leukemia, six cases of skin cancer, two cases of Hodgkin's disease, two cases of meningioma, and two cases of endometrial cancer were observed. This article confirms the feasibility of adjuvant CNF for early breast cancer patients. Questions of possible causability of secondary cancer have yet to be explored.

Abstract
Over the last years, significant survival benefits for breast cancer were derived from the use of postoperative systemic therapies and radiotherapy. Although these two modalities have been extensively used, the optimal strategies of their combining remain debatable. There have been few randomized studies addressing this issue and their results are generally inconclusive. This article reviews combining systemic therapies (chemotherapy, hormonotherapy and trastuzumab) with radiation in breast cancer patients. In clinical practice, chemotherapy and radiotherapy are most commonly used sequentially but this strategy is not based on level 1 evidence. Increased cardiotoxicity and skin reactions preclude the concomitant radiotherapy and anthracycline-based chemotherapy. Further investigations are warranted to determine the safety of taxane-based schedules used concomitantly with radiotherapy, particularly with regard to pneumotoxicity. Concurrent chemo-radiotherapy with the use of selected schemes may be considered in patients with locally advanced cancer but this strategy still needs to be verified in large randomized studies. The optimal combination of tamoxifen and aromatase inhibitors with radiotherapy has also not been determined in randomized trials and the results of retrospective studies are inconsistent. Finally, the data on combining targeted therapies with radiation are still scarce and do not allow for meaningful conclusions.

Abstract
BACKGROUND The optimal sequencing of chemotherapy and radiotherapy after breast surgery was largely studied but remains controversial. Concurrent chemo-radiotherapy is a valuable method for adjuvant treatment of breast cancer which is under ongoing research program in our hospital. We are evaluating the feasibility of the concomitant use of chemotherapy retrospectively. METHODS Two hundred forty four women having breast cancer were investigated in a retrospective study. All patients were either treated by radical surgery or breast conservative surgery. The study compares two adjuvant treatments associating concomitant chemotherapy and radiotherapy. In the first group (group A) the patients were treated by chemotherapy and radiotherapy in concomitant way using anthracycline (n = 110). In the second group (group B) the patients were treated by chemotherapy and radiotherapy in concomitant way using CMF treatment (n = 134). Chemotherapy was administered in six cycles, one each 3 weeks. Radiotherapy delivered a radiation dose of 50 Gy on the whole breast (or on the external wall) and/or on the lymphatic region. The Kaplan-Meier method was used to estimate the rates of disease free survival, loco-regional recurrence-free survival and overall survival. The Pearson Khi2 test was used to analyse the homogeneity between the two groups. The log-rank test was used to evaluate the differences between the two groups A and B. RESULTS After 76.4 months median follow-up (65.3 months mean follow up), only one patient relapsed to loco-regional breast cancer when the treatment was based on anthracycline. However, 8 patients relapsed to loco-regional breast cancer when the treatment was based on CMF. In the anthracycline group, the disease free survival after 5 years, was 80.4% compared to 76.4% in the CMF group (Log-rank test: p = 0.136). The overall survival after 5 years was 82.5% and 81.1% in the anthracycline and CMF groups respectively (Log-rank test: p = 0.428). The loco-regional free survival at 5 years was equal to 98.6% in group A and 94% in group B (Log-rank test: p = 0,033). The rate of grade II and grade III anaemia was 13.9% and 6.7% in anthracycline group and CMF group respectively (Khi2-test: p = 0.009). The rate of grade II and grade III skin dermatitis toxicity was 4.5% in the group A and 0% in the group B (Khi2-test: p = 0.013). CONCLUSION From the 5 years retrospective investigation we showed similar disease free survival and overall survival in the two concurrent chemo-radiotherapy treatments based on anthracycline and CMF. However in the loco-regional breast cancer the treatment based on anthracycline was significantly better than that of the treatment based on CMF. There was more haematological and skin dermatitis toxicity in the anthracycline group.

Abstract
PURPOSE In 1996, we initiated the French multicenter phase III randomized trial to compare the effect on disease-free survival (DFS) of concurrent versus sequential chemotherapy (CT) and radiotherapy (RT) after breast-conserving surgery for stages I and II breast cancer. This report presents the clinical results with a median follow-up of 60 months. PATIENTS AND METHODS Between February 1996 and April 2000, 716 patients were entered onto this trial. Adjuvant treatment began within 6 weeks after surgery. Sequential treatment of CT administered first followed by RT was compared with concurrent treatment of CT administered with RT. The CT regimen consisted of mitoxantrone (12 mg/m2), fluorouracil (500 mg/m2), and cyclophosphamide (500 mg/m2) on day 1, and it was repeated every 21 days for six courses. RT was delivered to the breast and, when indicated, to the regional lymphatics. RESULTS There was no statistically significant difference in treatment in the 5-year DFS (80% in both groups; P = .83), locoregional recurrence-free survival (LRFS; 92% in sequential v 95% in concurrent; P = .76), metastasis-free survival (87% in sequential v 84% in concurrent; P = .55), or overall survival (90% in sequential v 91% in concurrent; P = .76). Nevertheless, in the node-positive subgroup, the 5-year LRFS was statistically better in the concurrent arm (97% in concurrent v 91% in sequential; P = .02), corresponding to a risk of locoregional recurrence decreased by 39% (hazard ratio, 0.61; 95% CI, 0.38 to 0.93). CONCLUSION This treatment protocol remains an appealing clinical option for many women with operable breast cancer at a high risk of recurrence. Combination treatments with new drugs for breast cancer are warranted.

Abstract
BACKGROUND After surgery for localised breast cancer, adjuvant radiotherapy improves both local control and breast cancer specific survival. In patients at risk of harbouring micro-metastatic disease, adjuvant chemotherapy improves 15-year survival. However, the best sequence of administering these two types of adjuvant therapy for early stage breast cancer is not clear. OBJECTIVES To determine the effects of different sequencing of chemotherapy and radiotherapy for women with early breast cancer. SEARCH STRATEGY We searched the Cochrane Breast Cancer Group Specialized Register (10 March 2005). Details of the search strategy and methods of coding are described in the Group's module in The Cochrane Library. We extracted studies that had been coded as 'early', 'chemotherapy' and 'radiotherapy'. SELECTION CRITERIA Randomised controlled trials evaluating different sequencing of chemotherapy and radiotherapy were included. DATA COLLECTION AND ANALYSIS We assessed the eligibility and quality of the identified studies and extracted data from the published reports of the included studies. We derived odds ratios (OR) and risk ratios from the available numerical data. Hazard ratios were extracted directly from text. Toxicity data were extracted, where reported. We used a fixed-effect model for meta-analysis and conducted analyses on the basis of the method of sequencing of the two treatments. MAIN RESULTS Three trials reporting two different sequencing comparisons were identified. There were no significant differences between the various methods of sequencing adjuvant therapy for survival, distant metastases or local recurrence, based on 853 randomised patients in two trials. One of these two trials (647 women) provided data on toxicity. Haematological toxicity (OR 1.43, confidence interval (CI) 1.01 to 2.03) and oesophageal toxicity (OR 1.44, CI 1.03 to 2.02) were significantly increased with concurrent therapy, and nausea and vomiting were significantly decreased (OR 0.70, CI 0.50 to 0.98). Other measures of toxicity did not differ between the two types of sequencing. On the basis of one trial (244 women), radiotherapy before chemotherapy was associated with a significantly increased risk of neutropenic sepsis (OR 2.96, 95% CI 1.26 to 6.98) compared with chemotherapy before radiotherapy, but other measures of toxicity were not significantly different. AUTHORS' CONCLUSIONS The data included in this review, from three well conducted randomised trials, suggest that different methods of sequencing chemotherapy and radiotherapy do not appear to have a major effect on survival or recurrence for women with breast cancer if radiation therapy is commenced within 7 months after surgery.

Abstract
PURPOSE To comprehensively assess the current use of postmastectomy radiotherapy (PMRT) throughout China. METHODS AND MATERIALS A questionnaire on the indications and techniques for PMRT for breast cancer was mailed to all 715 radiotherapy centers in mainland China. RESULTS Of the 715 questionnaires sent out, 210 were answered (29.4%). The median interval between surgery and PMRT was 6 weeks. "Sandwich" sequencing of chemotherapy and PMRT was the most common combination, performed in 75.7% of the responding clinics. Of the respondents, 11.9% used PMRT for T1-T2N0 breast cancer, 63.8% for T1-T2N0 with tumors located in the center or inner quadrant, 87.6% for Stage T1-T2 and one to three positive lymph nodes (LN+), and 97.1% for T3 or Stage III tumors and/or four or more LN+. The supraclavicular region was the most common radiation target used by the respondents (96.2%), followed by the internal mammary chain (85.2%), chest wall (79.0%), and axilla (74.8%). Photon-based tangential fields were the most common technique used for chest wall irradiation (45.8%). The median total dose to each target was 50 Gy, with 2-Gy fractions. CONCLUSION A consensus has been reached in China that PMRT is needed for patients with T3 or Stage III disease and/or four or more LN+ and that irradiation to the chest wall and supraclavicular region is necessary in such patients. However, most Chinese radiation centers are also likely to apply PMRT to patients with one to three LN+ and to irradiate the internal mammary chain and the axilla.
