Abstract

Background The administration of endocrine therapy for 5 years substantially reduces recurrence rates during and after treatment in women with early-stage, estrogen-receptor (ER)–positive breast cancer. Extending such therapy beyond 5 years offers further protection but has additional side effects. Obtaining data on the absolute risk of subsequent distant recurrence if therapy stops at 5 years could help determine whether to extend treatment. Methods In this meta-analysis of the results of 88 trials involving 62,923 women with ER-positive breast cancer who were disease-free after 5 years of scheduled endocrine therapy, we used Kaplan–Meier and Cox regression analyses, stratified according to trial and treatment, to assess the associations of tumor diameter and nodal status (TN), tumor grade, and other factors with patients’ outcomes during the period from 5 to 20 years. Results Breast-cancer recurrences occurred at a steady rate throughout the study period from 5 to 20 years. The risk of distant recurrence was strongly correlated with the original TN status. Among the patients with stage T1 disease, the risk of distant recurrence was 13% with no nodal involvement (T1N0), 20% with one to three nodes involved (T1N1–3), and 34% with four to nine nodes involved (T1N4–9); among those with stage T2 disease, the risks were 19% with T2N0, 26% with T2N1–3, and 41% with T2N4–9. The risk of death from breast cancer was similarly dependent on TN status, but the risk of contralateral breast cancer was not. Given the TN status, the factors of tumor grade (available in 43,590 patients) and Ki-67 status (available in 7692 patients), which are strongly correlated with each other, were of only moderate independent predictive value for distant recurrence, but the status regarding the progesterone receptor (in 54,115 patients) and human epidermal growth factor receptor type 2 (HER2) (in 15,418 patients in trials with no use of trastuzumab) was not predictive. During the study period from 5 to 20 years, the absolute risk of distant recurrence among patients with T1N0 breast cancer was 10% for low-grade disease, 13% for moderate-grade disease, and 17% for high-grade disease; the corresponding risks of any recurrence or a contralateral breast cancer were 17%, 22%, and 26%, respectively. Conclusions After 5 years of adjuvant endocrine therapy, breast-cancer recurrences continued to occur steadily throughout the study period from 5 to 20 years. The risk of distant recurrence was strongly correlated with the original TN status, with risks ranging from 10 to 41%, depending on TN status and tumor grade.

BACKGROUND: Neoadjuvant chemotherapy (NACT) for early breast cancer can make breast-conserving surgery more feasible and might be more likely to eradicate micrometastatic disease than might the same chemotherapy given after surgery. We investigated the long-term benefits and risks of NACT and the influence of tumour characteristics on outcome with a collaborative meta-analysis of individual patient data from relevant randomised trials. METHODS: We obtained information about prerandomisation tumour characteristics, clinical tumour response, surgery, recurrence, and mortality for 4756 women in ten randomised trials in early breast cancer that began before 2005 and compared NACT with the same chemotherapy given postoperatively. Primary outcomes were tumour response, extent of local therapy, local and distant recurrence, breast cancer death, and overall mortality. Analyses by intention-to-treat used standard regression (for response and frequency of breast-conserving therapy) and log-rank methods (for recurrence and mortality). FINDINGS: Patients entered the trials from 1983 to 2002 and median follow-up was 9 years (IQR 5-14), with the last follow-up in 2013. Most chemotherapy was anthracycline based (3838 [81%] of 4756 women). More than two thirds (1349 [69%] of 1947) of women allocated NACT had a complete or partial clinical response. Patients allocated NACT had an increased frequency of breast-conserving therapy (1504 [65%] of 2320 treated with NACT vs 1135 [49%] of 2318 treated with adjuvant chemotherapy). NACT was associated with more frequent local recurrence than was adjuvant chemotherapy: the 15 year local recurrence was 21·4% for NACT versus 15·9% for adjuvant chemotherapy (5·5% increase [95% CI 2·4-8·6]; rate ratio 1·37 [95% CI 1·17-1·61]; p=0·0001). No significant difference between NACT and adjuvant chemotherapy was noted for distant recurrence (15 year risk 38·2% for NACT vs 38·0% for adjuvant chemotherapy; rate ratio 1·02 [95% CI 0·92-1·14]; p=0·66), breast cancer mortality (34·4% vs 33·7%; 1·06 [0·95-1·18]; p=0·31), or death from any cause (40·9% vs 41·2%; 1·04 [0·94-1·15]; p=0·45). INTERPRETATION: Tumours downsized by NACT might have higher local recurrence after breast-conserving therapy than might tumours of the same dimensions in women who have not received NACT. Strategies to mitigate the increased local recurrence after breast-conserving therapy in tumours downsized by NACT should be considered-eg, careful tumour localisation, detailed pathological assessment, and appropriate radiotherapy.

Abstract

BACKGROUND: Postmastectomy radiotherapy was shown in previous meta-analyses to reduce the risks of both recurrence and breast cancer mortality in all women with node-positive disease considered together. However, the benefit in women with only one to three positive lymph nodes is uncertain. We aimed to assess the effect of radiotherapy in these women after mastectomy and axillary dissection.METHODS: We did a meta-analysis of individual data for 8135 women randomly assigned to treatment groups during 1964-86 in 22 trials of radiotherapy to the chest wall and regional lymph nodes after mastectomy and axillary surgery versus the same surgery but no radiotherapy. Follow-up lasted 10 years for recurrence and to Jan 1, 2009, for mortality. Analyses were stratified by trial, individual follow-up year, age at entry, and pathological nodal status.FINDINGS: 3786 women had axillary dissection to at least level II and had zero, one to three, or four or more positive nodes. All were in trials in which radiotherapy included the chest wall, supraclavicular or axillary fossa (or both), and internal mammary chain. For 700 women with axillary dissection and no positive nodes, radiotherapy had no significant effect on locoregional recurrence (two-sided significance level [2p]>0·1), overall recurrence (rate ratio [RR], irradiated vs not, 1·06, 95% CI 0·76-1·48, 2p>0·1), or breast cancer mortality (RR 1·18, 95% CI 0·89-1·55, 2p>0·1). For 1314 women with axillary dissection and one to three positive nodes, radiotherapy reduced locoregional recurrence (2pINTERPRETATION: After mastectomy and axillary dissection, radiotherapy reduced both recurrence and breast cancer mortality in the women with one to three positive lymph nodes in these trials even when systemic therapy was given. For today's women, who in many countries are at lower risk of recurrence, absolute gains might be smaller but proportional gains might be larger because of more effective radiotherapy.FUNDING: Cancer Research UK, British Heart Foundation, UK Medical Research Council.

Abstract

Aim To evaluate diffusion-weighted magnetic resonance imaging (DW-MRI) for detection of regional nodal metastases in primary head and neck squamous cell carcinoma (HNSCC). Materials and methods Ten patients with HNSCC underwent an MRI prior to surgery. The scan protocol consisted of plain transverse T1- and T2-weighted turbo spin echo (TSE) sequences and gadolinium-enhanced transverse, coronal and sagittal T1-weighted TSE sequences. Additionally, a transverse echo-planar DW-MRI sequence, using six b-values between 0 and 1000s/mm2, was performed. Apparent diffusion coefficient (ADC) maps were calculated for the entire b-value range (ADC avg) and for the high b-values separately (b≥500s/mm2, ADC high). ADC values were compared with histopathology of the neck dissection specimens. After determining an optimal threshold for ADC avg and ADC high, sensitivity and specificity was calculated. Finally DW-MRI was compared with TSE-MRI for detection of nodal metastases. Results MRI showed 55 lymph nodes; 41 were benign and 14 malignant on histopathology. The mean ADC avg value for benign lymph nodes was 0.00122±0.00029mm2/s and 0.00090±0.00014mm2/s for malignant nodes (p, Aim To investigate the incidence, localization and prognostic influence of retropharyngeal (RP) nodal involvement in patients with squamous cell carcinoma of the oropharynx. Methods The CT studies of 208 patients presenting with oropharyngeal carcinoma were retrospectively analysed. The location of nodal neck disease was registered according to recent consensus guidelines for target volume delineation, and special attention was given to the RP nodes. The influence on recurrence (local and regional), distant metastasis, and survival was investigated. Results RP adenopathies were present in 16% (34/208) of all patients and in 23% (31/134) of patients with nodal disease in other neck sites. A solitary ipsilateral RP node was present in 3 (9%) of 34 patients with RP nodes; 2 of these 3 patients had a primary posterior pharyngeal wall tumour. No patients presented with a solitary contralateral RP node. At 5 years, patients with RP adenopathy had significantly more regional recurrences (45% vs. 10%, p=0.004). Involvement of RP lymph nodes significantly (RR 4.29 [95% CI 3.33–5.25], p=0.01) and independently predicted regional recurrence in multivariate analysis. Disease-specific survival was significantly lower in the RP node positive group (38% vs. 58%, p=0.03). Conclusions Given the high incidence of RP nodal involvement in oropharyngeal cancer and the negative impact on prognosis, RP nodes should be included in the target volume, especially in node-positive necks. In node-negative necks, inclusion of RP nodes into the target volume is advised in posterior pharyngeal wall tumours., Aim Acanthomatous change (AC) has been described as a sign of greater malignancy. However, it is generally accepted that histomorphological variations have no bearing on biologic behaviour or prognosis and that there is no correlation between histologic subtype and radiologic/imaging findings. Materials and methods In a review of 20 cases of aggressive ameloblastoma over a 12-year period (1991–2002), AC was often stated in histological reports, without any special clinical significance or pathological quantification, radiological correlation or proven clinical implication. In this study, AC was classified as focal or diffuse (from 1+ to 4+) and correlated with the radiological appearance and clinical behaviour. Results AC occurred in the follicular and plexiform subtypes. Fourteen cases were recurrences. It was conclusively shown that progressive AC was associated with an aggressive radiological appearance and biologic behaviour, including a case of ameloblastic carcinoma. Conclusion AC correlates with aggressive behaviour. Pathologists and clinicians should be alerted to the significance of AC in biopsy and resected histological specimens. These cases should be carefully assessed by MRI for diagnosis and follow up., Aim To investigate sentinel lymph node mapping in patients with early stage breast carcinoma. Methods A systematic search of world literature of sentinel node mapping in patients with early stage breast carcinoma following chemotherapy was undertaken. Using the keywords ‘sentinel node biopsy’, ‘early stage breast cancer’, ‘axillary lymph node dissection’ and ‘lymphatic mapping’, potentially eligible studies were identified. Results Between 2000 and 2005, 24 trials were reported that met eligibility criteria. Of the 1247 patients studied, 1047 patients (84%) had successfully mapped lymph nodes. The proportion of patients who had successful lymph node mapping ranged from 63% to 100%, with 55% of studies reporting a rate of, Aim To investigate the behaviour of the dynamic optical breast imaging (DOBI) curve in relation to the microvessel density (MVD) count of surgical specimens from breast biopsies. Methods Forty-six patients underwent DOBI evaluation for mammographic findings suggesting biopsy. The DOBI evaluation was performed the day before or on the day of the scheduled biopsy. The MVD count was performed from the site of the specimen where the pathology was located. The characteristics of the DOBI curve were correlated to the MVD count and to the pathology results of the biopsy. Results All malignant lesions had a high MVD count and a DOBI curve with a downslope direction, rather straight and without any initiation delays. The benign cases with a high MVD count had a downslope DOBI curve but not always straight and with some initiation delays. The rest of the cases had a low MVD count and most of them an elevated DOBI curve. Conclusion Our preliminary results indicate a relationship between malignant breast lesions with a characteristic DOBI curve and high MVD count., Aim To assess magnetic resonance (MR) imaging features of breast lymphoma (BL) and to compare MR characteristics of BL and ductal infiltrating carcinoma (DIC). Methods MR features of 7 patients with 7 breast lymphoma lesions (BL) and 7 patients with 9 DIC lesions were retrospectively evaluated by two radiologists, according to a multifactorial evaluation protocol (8-point scale) for lesion morphology (form, margins, and enhancing pattern) and dynamics (initial wash-in peak and post-initial washout). Signal intensity values of pre-contrast, initial and post-initial enhancement were recorded in order to calculate percentage changes of these values for BL and DIC lesions. Diameter of lesions was also recorded. The Wilcoxon two-sample test was used to evaluate the differences between BL and DIC MR features. The same statistical test was used to assess the inter-observer variability. Results BL showed a significantly higher median diameter (median 38 mm, range 25–50 mm) than DIC (median 20 mm, range 15–23 mm) (p0.05). There was no significant inter-observer variability for all the assessed data (p>0.05). Conclusion MR evaluation of BL and DIC lesions did not show significant difference in initial enhancement percentage change and overall evaluation score. There was significant difference between the two groups in diameter and percentage change of post-initial enhancement., Aim To determine the presence, severity and distribution of morphological changes consistent with ‘fibrosis’ and fatty infiltration on MRI with SPIO in patients with colorectal metastases, and their relationship to chemotherapy. Methods One-hundred and seventeen patients with colorectal metastases, 89 undergoing chemotherapy and 28 untreated, underwent unenhanced in-phase and opposed-phase T1-weighted gradient refocused echo (GRE) imaging, and T2-weighted fast spin echo (FSE) and GRE sequences before and after 8 μmol /kg ferucarbotran. The images were reviewed by two experienced observers to determine the presence, severity and distribution of morphological changes consistent with ‘fibrosis’ and fatty infiltration. Percentage signal intensity loss (PSIL) and tumour-to-liver contrast (CNR) were measured on superparamagnetic iron oxide (SPIO)-enhanced liver images. Results In the post-chemotherapy patients the mean PSIL, mean CNR were 51.9, 6.7 on FSE and 70.7, 29.6 on GRE sequences, respectively. In untreated patients the mean PSIL, mean CNR were 54.9, 8.3 on FSE and 74.1, 32.4 on GRE. Twenty-five patients (19 treated, 6 untreated) had ‘fibrosis’ (4 severe, 21 moderate), which was extensive in 11 and localised in 14. Compared with the non-fibrotic group (n=92), the 25 patients with ‘fibrosis’ had significantly lower PSIL (47.5 v 54.1 [p, Aim To monitor by CTp perfusion, changes in hepatocellular carcinoma (HCC) following therapy with thalidomide. To correlate tumour perfusion with alpha-fetoprotein (AFP) and circulating endothelial cells (CEC). To investigate whether baseline tumour perfusion may predict therapy outcome. Methods Thirteen consecutive patients with advanced HCC, treated with orally administered thalidomide (200 mg /day), underwent baseline CTp and follow-up CTps, every 8 weeks. On May 2006 nine patients reached follow-up >6 months. Perfusion parameters (blood flow (BF), blood volume (BV), mean transit time (MTT), permeability surface (PS)) of the tumours were calculated using dedicated software (CT Perfusion 3, GE) and statistically correlated with AFP and CEC. Results Twelve patients were assessable for response (one excluded for toxicity); none had partial or complete remission; 6 had stable disease (SD) at 6 months and 3 had progressive disease (PD). All patients with PD showed increased BF (average 30.57%) at the time of PD; all patients with SD had stable or reduced BF (average −13.3%) at 6 months. Significant correlation between BF and AFP changes was found (R=0.71). Baseline BF and BV of HCC were significantly higher (p, Aim Pseudomyxoma peritonei (PP) is a rare condition characterised by mucinous ascites and mucinous implants involving the peritoneal surfaces. The pathology of PP has been defined into three groups: disseminated peritoneal adenomucinosis (DPAM), peritoneal mucinous carcinomatosis (PMCA) and the hybrid type. The aim of the retrospective study was to describe the computed tomography (CT) findings of 51 patients referred to our institution for surgical cytoreduction. Methods Two observers independently reviewed the CT images performed between 1996 and 2004. Results There were 38 patients with PMCA (18 women, 20 men, mean age 59 years) and 13 with DPAM (8 women, 5 men, mean age 55 years). No hybrid type of PP was encountered. Pleural effusion or pleural rind, omental cake and paraaortic lymph nodes were seen only in cases of PMCA. Liver and spleen scalloping as well as hernias were also common in PMCA. Calcifications were seen in 36% of DPAM and 26% of PMCA examinations. Conclusions Pseudomyxoma peritonei is difficult to diagnose clinically. However, knowledge of typical CT findings can help the radiologist to suggest a diagnosis of PP., Aim To compare prospectively the accuracy of ferucarbotran-enhanced high-resolution dynamic T1-weighted imaging and delayed T2-weighted gradient refocused echo (GRE) imaging for detecting small metastases. Methods We studied 25 patients referred for liver resection with colorectal metastases. All were imaged with dynamic T1-weighted fat-suppressed 3D GRE (VIBE) and delayed T2-weighted GRE sequences after bolus injection of ferucarbotran. Images were independently evaluated by two blinded observers who identified and localised lesions using a four-point confidence scale. Only lesions smaller than 2 cm were included in the analysis. The results were correlated with surgery, intra-operative ultrasound and histopathology. AFROC analysis was used to determine the accuracy of each technique. Results One-hundred and forty-seven metastases, smaller than 2 cm (107 < 1 cm) were present. For all metastases the accuracy values were 0.94 and 0.92 for T1-weighted and 0.93 and 0.91 for T2-weighted, respectively, for each of two observers. Accuracy values for lesions of 1 cm or less were 0.93 and 0.89 for T1-weighted and 0.91 and 0.88 for T2-weighted. Nine sub-centimetre lesions were not detected by either observer on any technique. Overall 11/147 (7.5%) lesions were detected only on T1-weighted (mean of two observers) compared with 7/147 (4.7%) detected only on T2-weighted (all less than 1 cm). Conclusion Accuracy for ferucarbotran-enhanced T1- and T2-weighted imaging was similar. With combined T1- and T2-weighted imaging we detected substantially more lesions than either sequence alone., Aim To compare the performance of tri-phasic multidetector computed tomography (MDCT) and gadoxetate (formerly known as Gd-EOB-DTPA, Primovist ®, Schering, Germany)-enhanced magnetic resonance (MR) imaging in detection and characterization of focal liver lesions. Methods The study population consisted of 34 patients, who underwent triphasic MDCT and Gd-EOB-DTPA enhanced 1.5-T MRI (time interval, max 14 days), including dynamic and late phase gadoxetate-T1-weighted scans at 20 and 40 min. Two radiologists evaluated the images in consensus reading with respect to lesion size, number, location and characterisation. Gold standard was defined by histopathologic correlation, intra-operative ultrasound or imaging follow up. The McNemar test was used for statistical analysis. Results Of a total of 126 lesions CT detected 78% and MRI 93% (p=0.003), respectively. The correct characterisation of lesions was accomplished in 64% with CT and in 89% with MRI (p, Aim To evaluate the preoperative TNM-staging of oesophageal carcinomas with contrast enhanced 16-or 64-row multidetector computed tomography (MDCT) and to compare the findings with results by endoscopic ultrasound (EUS), using the histopathological findings as gold standard. Methods Eighty-six patients with oesophageal carcinoma (proven by endoscopic biopsy) were preoperatively examined with MDCT in a prone position. After distending the oesophagus (gas granules) and stomach (1.5 L of water) the chest and neck were subjected to MDCT scanning with 16×0.75 mm or 64×0.63 mm, the abdomen with 16×1.5 or 64×1 mm, using an individualised contrast injection protocol based on a bolus tracking technique. EUS was performed using a fibre-optic endoscope with a 5–10 MHz electronic array with a 360 degree scanning angle. Our MDCT staging criteria were drawn from a careful review of the literature and from personal experience and we used the TNM classification of the American Joint Committee on Cancer. Results Both modalities detected all tumours with a sensitivity of 100%. T staging by MDCT and EUS reached accuracies of 79% and 89%. The diagnosis of local node involvement by MDCT was correct in 85%, in EUS in 72%. The evaluation of distant node involvement and other metastases reached an accuracy of 92% with MDCT and only 65% with EUS. Conclusion Non-invasive MDCT is an important tool in the preoperative staging of oesophageal carcinoma and is complementary to EUS.

Abstract

Contains fulltext : 153199.pdf (publisher's version ) (Open Access), BACKGROUND: The effect of internal mammary and medial supraclavicular lymph-node irradiation (regional nodal irradiation) added to whole-breast or thoracic-wall irradiation after surgery on survival among women with early-stage breast cancer is unknown. METHODS: We randomly assigned women who had a centrally or medially located primary tumor, irrespective of axillary involvement, or an externally located tumor with axillary involvement to undergo either whole-breast or thoracic-wall irradiation in addition to regional nodal irradiation (nodal-irradiation group) or whole-breast or thoracic-wall irradiation alone (control group). The primary end point was overall survival. Secondary end points were the rates of disease-free survival, survival free from distant disease, and death from breast cancer. RESULTS: Between 1996 and 2004, a total of 4004 patients underwent randomization. The majority of patients (76.1%) underwent breast-conserving surgery. After mastectomy, 73.4% of the patients in both groups underwent chest-wall irradiation. Nearly all patients with node-positive disease (99.0%) and 66.3% of patients with node-negative disease received adjuvant systemic treatment. At a median follow-up of 10.9 years, 811 patients had died. At 10 years, overall survival was 82.3% in the nodal-irradiation group and 80.7% in the control group (hazard ratio for death with nodal irradiation, 0.87; 95% confidence interval [CI], 0.76 to 1.00; P=0.06). The rate of disease-free survival was 72.1% in the nodal-irradiation group and 69.1% in the control group (hazard ratio for disease progression or death, 0.89; 95% CI, 0.80 to 1.00; P=0.04), the rate of distant disease-free survival was 78.0% versus 75.0% (hazard ratio, 0.86; 95% CI, 0.76 to 0.98; P=0.02), and breast-cancer mortality was 12.5% versus 14.4% (hazard ratio, 0.82; 95% CI, 0.70 to 0.97; P=0.02). Acute side effects of regional nodal irradiation were modest. CONCLUSIONS: In patients with early-stage breast cancer, irradiatio

Abstract

BACKGROUND: After breast-conserving surgery, radiotherapy reduces recurrence and breast cancer death, but it may do so more for some groups of women than for others. We describe the absolute magnitude of these reductions according to various prognostic and other patient characteristics, and relate the absolute reduction in 15-year risk of breast cancer death to the absolute reduction in 10-year recurrence risk. METHODS: We undertook a meta-analysis of individual patient data for 10,801 women in 17 randomised trials of radiotherapy versus no radiotherapy after breast-conserving surgery, 8337 of whom had pathologically confirmed node-negative (pN0) or node-positive (pN+) disease. FINDINGS: Overall, radiotherapy reduced the 10-year risk of any (ie, locoregional or distant) first recurrence from 35.0% to 19.3% (absolute reduction 15.7%, 95% CI 13.7-17.7, 2p/=20%), intermediate (10-19%), or lower (, link_to_OA_fulltext

Abstract

National audience; INTRODUCTION: The EORTC 22922/10925 trial investigated the potential survival benefit and toxicity of elective irradiation of the internal mammary and medial supraclavicular (IM-MS) nodes Accrual completed in January 2004 and first results are expected in 2012. We present the toxicity reported until year 3 after treatment. PATIENTS AND METHODS: At each visit, toxicity was reported but severity was not graded routinely. Toxicity rates and performance status (PS) changes at three years were compared by chi(2) tests and logistic regression models in all the 3,866 of 4,004 patients eligible to the trial who received the allocated treatment. RESULTS: Only lung (fibrosis; dyspnoea; pneumonitis; any lung toxicities) (4.3% vs. 1.3%; p < 0.0001) but not cardiac toxicity (0.3% vs. 0.4%; p = 0.55) significantly increased with IM-MS treatment. No significant worsening of the PS was observed (p = 0.79), suggesting that treatment-related toxicity does not impair patient's daily activities. CONCLUSIONS: IM-MS irradiation seems well tolerated and does not significantly impair WHO PS at three years. A follow-up period of at least 10 years is needed to determine whether cardiac toxicity is increased after radiotherapy.

Abstract

The study aimed at evaluating the potential benefit from a combination of fractionated ionising radiation with the vascular-targeting compound combretastatin A-4 phosphate (CA-4-P).Syngenic rat rhabdomyosarcoma (R1), growing subcutaneously, was treated at 2 different sizes: either small (2 +/- 0.5 cm3) or large (10.94 +/- 0.6 cm3). Localised fractionated irradiation of the tumours (5 x 3 Gy) in 5 days was followed 1 day later by an intraperitoneal CA-4-P treatment (25 mglkg).The combined treatment of only large tumours resulted in a small additional growth delay when compared with radiotherapy only.The present data indicate a size-dependent increase in tumour growth delay from combining fractionated irradiation with CA-4-P.

Abstract

PURPOSE: To present the results of the dummy run of the European Organization for Research and Treatment of Cancer (EORTC) trial investigating the role of adjuvant internal mammary and medial supraclavicular (IM-MS) irradiation in Stage I--III breast cancer. METHODS AND MATERIALS: All participating institutions were asked to produce a treatment plan without (Arm 1) and with (Arm 2) simultaneous IM-MS irradiation of 1 patient after mastectomy and of 1 patient after lumpectomy. Thirty-two dummy runs have been evaluated for compliance to protocol guidelines, with respect to treatment technique and dose prescription. RESULTS: A number of more or less important deviations in treatment setup and prescription have been found. The dose in the IM-MS region deviated significantly from the prescribed dose in 10% of the cases for Arm 1, and in 21% for Arm 2. Assuming a true 5% 10-year survival benefit from optimal IM-MS irradiation, an increase of only 3.8% will be found due to this suboptimal dose distribution. CONCLUSION: In the dummy run, a number of potential systematic protocol deviations that might lead to false-negative results were detected. By providing recommendations to the participating institutions, we expect to improve the interinstitutional consistency and to promote a high quality irradiation in all institutions participating in the trial

Abstract

Contains fulltext : 71420.pdf (publisher's version ) (Closed access), The EORTC 22881-10882 trial in 5178 conservatively treated early breast cancer patients showed that a 16 Gy boost dose significantly improved local control, but increased the risk of breast fibrosis. To investigate predictors for the long-term risk of fibrosis, Cox regression models of the time to moderate or severe fibrosis were developed on a random set of 1797 patients with and 1827 patients without a boost, and validated in the remaining set. The median follow-up was 10.7 years. The risk of fibrosis significantly increased (P<0.01) with increasing maximum whole breast irradiation (WBI) dose and with concomitant chemotherapy, but was independent of age. In the boost arm, the risk further increased (P<0.01) if patients had post-operative breast oedema or haematoma, but it decreased (P<0.01) if WBI was given with >6 MV photons. The c-index was around 0.62. Nomograms with these factors are proposed to forecast the long-term risk of moderate or severe fibrosis.

Abstract

Contains fulltext : 51878.pdf (publisher's version ) (Closed access), PURPOSE: To determine whether the effect of an additional "boost" radiation after breast conservative therapy (BCT) on local control depends on age and evaluate the impact of a treatment policy with a threshold for age. PATIENTS AND METHODS: We used data from EORTC 22881-10882 trial, with median follow-up of 77.4 months. Patients receiving BCT and 50Gy whole breast irradiation were randomized to no boost and 16Gy boost (N=5318). RESULTS: In univariate analysis, a boost reduced local failure by a factor of 2 (P<0.0001). Multivariate analysis showed local control increased with age (P=0.0003). There was no evidence that the relative effect of a boost on local control depends on age (P=0.97) However in younger patients the 5-year local failure was higher, therefore the absolute reduction was greater. If the threshold-age for boost treatment were set at 40 years, 8.4% of the study population would receive a boost, resulting in a 5-year local failure of 6.1% in the study population. Changing the threshold-age to 60 years, 67% of the study population would receive a boost and the 5-year local failure would be reduced to 4.4%. CONCLUSIONS: In younger patients a boost dose resulted in a greater absolute reduction of local failure. The relative risk reduction was however similar for all ages. Applying a treatment policy with a threshold-age of 60 would result in 0.6% increase in local failure in the total study population, while sparing the boost to 1/3 of the patients.

Abstract

Contains fulltext : 52922.pdf (publisher's version ) (Closed access), PURPOSE: To investigate the long-term impact of a boost radiation dose of 16 Gy on local control, fibrosis, and overall survival for patients with stage I and II breast cancer who underwent breast-conserving therapy. PATIENTS AND METHODS: A total of 5,318 patients with microscopically complete excision followed by whole-breast irradiation of 50 Gy were randomly assigned to receive either a boost dose of 16 Gy (2,661 patients) or no boost dose (2,657 patients), with a median follow-up of 10.8 years. RESULTS: The median age was 55 years. Local recurrence was reported as the first treatment failure in 278 patients with no boost versus 165 patients with boost; at 10 years, the cumulative incidence of local recurrence was 10.2% versus 6.2% for the no boost and the boost group, respectively (P < .0001). The hazard ratio of local recurrence was 0.59 (0.46 to 0.76) in favor of the boost, with no statistically significant interaction per age group. The absolute risk reduction at 10 years per age group was the largest in patients

Abstract

Contains fulltext : 59361.pdf (publisher's version ) (Closed access), BACKGROUND AND PURPOSE: The EORTC Trial 22881/10882 investigating the role of a boost dose in breast conserving therapy demonstrated a significantly better local control rate with the higher radiotherapy dose, especially in women younger than 50 years of age. This paper investigates the potential impact of the different boost techniques on local control and on fibrosis after breast conserving therapy. PATIENTS AND METHODS: From 1989 to 1996, 2661 patients were randomised to receive a boost dose of 16Gy to the primary tumour bed after microscopically complete tumorectomy and 50Gy whole breast irradiation. The choice of the boost technique was left to the treating investigator. Treatment data were prospectively recorded as well as the clinical outcome in terms of local control and fibrosis. Sixty-three percent of the patients received a boost dose with fast electrons, 28% with photon beams and 9% with interstitial brachytherapy. RESULTS: At 5 years, local recurrences were seen in 74 of the 1635 patients who received an electron boost (4.8%, CI 3.6-5.9%), in 28 of the 753 patients who received a photon boost (4.0%, CI 3.4-5.5%) and in 6 of the 225 patients after an interstitial boost (2.5%, CI 0.3-4.6%). The grade of fibrosis in the whole breast as well as at the primary tumour bed, as scored by the treating radiation oncologist, was similar in the three groups. CONCLUSIONS: Although the three groups are of a rather unequal size, the results of the interstitial boost seem similar in terms of fibrosis and at least as good in terms of local control, despite a lower treatment volume and a longer overall treatment time.

Abstract

Item does not contain fulltext, The aim of this study was to identify patient-, tumour- or treatment-related factors associated with young age that might explain the higher risk of ipsilateral breast recurrence that occurs after breast-conserving therapy (BCT) in young breast cancer patients. In the 'boost versus no boost trial', 5569 early-stage breast cancer patients were entered. All patients underwent tumorectomy followed by whole breast irradiation of 50 Gy. Patients having a microscopically complete excision were randomised between receiving no boost or a 16-Gy boost, while patients with a microscopically incomplete excision were randomised between receiving a boost dose of 10 or 26 Gy. The 5-year local control rate was 82% for patients 60 years of age (P<0.0001). In young patients, the tumour was significantly larger and more often oestrogen and progesterone receptor-negative. Invasive carcinoma and the intraductal component were more often of a high grade. The intraductal component was more frequently incompletely resected in young patients. Re-excisions were performed more often (most probably due to a more frequent incomplete excision at the first attempt). The total volume of breast tissue removed at the tumorectomy was smaller in the younger patient group, even after including the volume removed during re-excision. When relating all these parameters (including age itself) to local control, the multivariate analysis stratified by treatment showed that age was the only independent prognostic factor for local control (P=0.0001). Including the boost treatment as a separate covariate, the analysis retained age and boost treatment as significant factors related to local control (P<0.0001). It was shown that the boost dose significantly reduced the 5-year local recurrence rate from 7 to 4% for patients with a complete excision (P<0.001). For patients 40 years of ag
