Abstract
OBJECTIVE: To develop a mathematical model for cardiac dose estimation for patients who have been treated for left-sided breast cancer without CT data. METHODS: After obtaining institutional review board approvals, 147 patients with left-sided breast cancer were selected that were treated supine with opposed tangents. The heart blocks from the tangential fields were removed and dose calculations were performed with 6 MV beams using an advanced algorithm. This study was performed with CT data with DRR to represent a radiographic simulator image of yesteryear treatments. The beam's eye-view images showing delineated breast, lung and heart were created to represent views on radiograph. The maximum heart distance (MHD) was recorded and irradiated heart area (AREA) was computed by combination of triangles and rectangles. Based on accurate 3D dose calculation, mean dose (Dmean) and V10 to V50 of heart were analyzed with respect to MHD and AREA for dosimetric parameters using linear and quadratic fit. RESULTS: The treatment parameters calculated by MHD and segments using 2D radiographs were within 2% of the actual dosimetric parameters computed from the 3D planning system. The MHD and AREA vs Dmean, V10, V20, V30 and V50 showed very good correlation with linear model (R2 > 0.91); however the correlation was significantly better with quadratic model (R2 > 0.92). The analysis of the dosimetric error with our linear and quadratic model is remarkable within <3% error for most cases. CONCLUSION: The proposed mathematical model for the cardiac dose estimation is accurate within ±3% using a radiograph without CT data. This provides avenues for patient pooling in future studies related to radiation dose and cardiac toxicity. These results will help in estimating cardiac dose analysis accurately from previous studies as well as in centers still using 2D planning. ADVANCES IN KNOWLEDGE: The evidence of cardiac risk following radiotherapy continues to be one of the important considerations for the management of left-sided breast cancer patients. One of the problem in the estimation of dose-risk effects is the reconstruction of heart dose for pre-CT treatments. In this study, a simple mathematical model is presented that could estimate cardiac dose within ±3% in left breast cancer treatment from 2D radiograph where CT data do not exist.

Abstract
Aims and backgrounds This paper describes the evaluation of a personal series of 106 breast cancer patients, aged 28-75 years (average, 54), treated between 1988 and 1971, to determine the success of a conservative protocol proposed as a means of combining radicality with a better cosmetic result, less alteration of the body image and an improved quality of life. Methods All the patients were operated with quadrantectomy and excision of axillary lymph nodes, followed by radiotherapy: 50 Gy to the whole breast plus 10 Gy on the tumor bed (boost irradiation). Adjuvant hormone and/or chemotherapy was also administered in 71/106 cases. The mean follow-up was 22.3 months. Cosmetic assessment was subjective and objective (asymmetry, loss of volume, retraction). All patients were photographed. Results The subjective judgements were: excellent 79, satisfactory 25, and poor 2, compared with objective assessments of 72, 20 and 14, respectively. Patients with poor esthetic results were almost all either T2 or treated with chemotherapy. Conclusions Conservative treatment of breast cancer using integrated irradiation and surgery can therefore attain the required objective of eradication of the cancer while maintaining a satisfactory esthetic and therefore good psychologic outcome.

Abstract
Purpose To evaluate retrospectively factors influencing the cosmetic outcome after conservative treatment for breast cancer. Material and methods From 1988 until 1992, 164 patients were treated with conservative surgery (quadrantectomy) and radiotherapy with 60Co (50 Gy on the whole breast) plus 10 Gy on the surgical bed (300 kV photons) for T1–T2 breast cancers; 46 patients (28%) received concomitant adjuvant chemotherapy (CMF schedule). Cosmesis evaluation was carried out after 24 to 108 months (median, 38 months). A logistic regression analysis was performed to identify independent variables influencing the aesthetic outcome. P values of 0.05 or less were considered significant. Results Univariate analysis showed that T2 versus T1 (P = 0.0102), lower quadrants site (P = 0.0002) and concomitant adjuvant chemotherapy (P = 0.0009) produced a worse aesthetic outcome. Multivariate analysis confirmed the same factors: tumor size (P = 0.0020), tumor site (P = 0.0150) and concomitant chemotherapy (P = 0.0024). Conclusions The significant negative influence on the cosmetic outcome of concomitant adjuvant chemotherapy implies questions about the timing of radiotherapy and chemotherapy in breast cancer conservative treatment.

Abstract
Aim and background To identify the factors influencing cosmesis after conservative treatment in breast cancer. Methods Retrospective analysis was done on 424 patients who underwent postoperative radiotherapy after conservative surgery for breast cancer from February 1992 to January 2002. Most of the patients underwent quadrantectomy. Whole breast irradiation up to 50.4 Gy was delivered in 28 fractions followed by a 10 Gy boost in 5 fractions to the tumor bed. Regional lymph node irradiation was administered if indicated. Breast cosmesis was scored in 4 tiers. Breast symmetry was analyzed by the relative distance from the sternal notch to the nipple, using photos taken prior to radiotherapy and 2 years after its completion. Median follow-up was 64 months. Results Breast cosmesis was excellent in 15%, good in 63%, fair in 19%, and poor in 3% of the patients. In multivariate analysis, tumors >2 cm ( P = 0.0109), lower quadrant location ( P = 0.0026), lymph node irradiation ( P = 0.0028), and heat exposure ( P = 0.0152) were related to poor cosmesis. The cosmesis score after radiotherapy compared to the pre-radiotherapy score was deteriorated in patients who had undergone lymph node irradiation ( P <0.0001) and heat exposure ( P = 0.0027). Breast symmetry was worse for patients who had tumors >2 cm ( P <0.0001), upper quadrant tumor location ( P <0.0001), chemotherapy in combination with radiotherapy ( P = 0.0136), lymph node irradiation ( P = 0.0006) and heat exposure ( P = 0.0355). Changes in symmetry by radiotherapy were greater for lymph node-irradiated patients ( P <0.0001). Conclusions With larger tumor size, lymph node irradiation, and chemotherapy in combination with radiotherapy, heat exposure was found to have a negative impact on cosmesis in patients undergoing conservative treatment for breast cancer. Patients should therefore be advised to avoid heat exposure after breast irradiation.

Abstract
Oncoplastic breast conserving surgery (BCS) has emerged as a third option between conventional BCS and mastectomy. Oncoplastic BCS includes two fundamentally different approaches: volume replacement and volume displacement. The former involves partial mastectomy and immediate reconstruction of the breast with the transposition of autologous tissue from elsewhere, while the latter involves partial mastectomy and using the remaining breast tissue to fill the defect resulting from extirpation of the tumor. There are several benefits associated with oncoplastic BCS. First, it allows partial mastectomy without cosmetic penalties, and can achieve better cosmetic outcomes than total mastectomy with immediate breast reconstruction. Second, it avoids the need for total mastectomy in an increasing number of patients without compromising local control. Third, partial breast reconstruction is less extensive and has fewer complications than conventional procedures. Partial mastectomy and partial breast reconstruction can be carried out either simultaneously as a one-stage procedure, or using a two-stage approach. Although patients prefer a one-stage procedure, it requires intraoperative confirmation of complete tumor excision using frozen-section analysis. Moreover, oncoplastic BCS requires combined skills, knowledge, and understanding of both oncological and plastic surgeries, which may be optimally achieved by an oncoplastic surgeon.

Long-term outcome of breast cancer patients treated with radiofrequency ablation. Eur J Surg Oncol 2012; 38:1036-42. [PMID: 22947631 DOI: 10.1016/j.ejso.2012.08.006] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2012] [Revised: 07/30/2012] [Accepted: 08/13/2012] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Radiofrequency ablation (RFA) is considered to be the most promising non-surgical ablation technique for the treatment of small breast cancer. However, few data are available regarding long-term follow-up of patients treated with this modality. METHODS Since 2005, we have performed RFA and sentinel lymph node (SLN) biopsy in 19 cases. Axillary lymph node dissection (ALND) was performed in patients with positive SLNs. From 24 to 202 days after RFA, the ablated tumour tissue was excised by mammotome biopsy and examined histologically or immunohistochemically with H&E staining, nicotinamide adenine dinucleotide (NADH)-diaphorase staining, and single-stranded (ss) DNA staining. All cases were followed-up after breast radiation and systemic therapies. RESULTS Although complete response was histologically confirmed in only 8 cases, NADH-diaphorase and ssDNA staining did not demonstrate any viable tumour cells in the ablated lesions. At a mean follow-up of 60 months (follow-up range, 37-82 months), there were no cases of in-breast recurrence, although one patient died due to hepatic metastases. Cosmesis of the conserved breast was excellent or good in all of the cases, but a hard lump was persistent after RFA in half of the cases. CONCLUSIONS The long-term outcome of patients treated with RFA is encouraging with regard to cosmesis and local control. Because a persisted lump may cause patient discomfort, anxiety and fear, however, further studies are needed to establish the optimal technique. Moreover, a prospective study will be required to determine the equivalency in local recurrence rates between the RFA therapy and conventional breast-conserving treatment.

Abstract
OBJECTIVE The aim of the present retrospective study was to compare two breast-conserving techniques, segmental resection and standard lumpectomy, for the treatment of breast cancer regarding their oncological safety. Quality of life aspects were evaluated by assessing the respective postsurgical cosmetic results. PATIENTS AND METHODS 190 women with breast cancer located in the superior and lateral quadrant were included in the study. Sixty patients were treated with segmental resection (group 1), whereas 130 underwent standard lumpectomy (group 2). Tumor sizes were determined and excised tissue specimens were analyzed for positive or negative resection margins. Patients were given a 16-item questionnaire for the postsurgical self-assessment of the cosmetic outcome. RESULTS No statistically significant difference was found concerning the number of positive resection margins between the groups (25 vs. 30%, p = 0.46). Exceptions were ventral margins, which predominated in group 2 (p = 0.016). Group 1 revealed a significantly larger maximum tumor size with negative margins as compared to group 2 (26.6 vs. 17.0 mm). General satisfaction with the cosmetic results was comparable between groups. CONCLUSIONS Segmental resection surgery, as a method of breast conservation therapy, can be used to treat larger breast lesions as compared to standard lumpectomy.

Abstract
PURPOSE The efficacy of immediate breast reconstruction using a free dermal fat graft (FDFG) was evaluated clinically. PATIENTS AND METHODS A total of 22 breasts in 21 patients who underwent partial mastectomy for early breast cancer involving mainly the inner upper quadrant were enrolled in this study. The defect was reconstructed immediately by filling it with an autologous FDFG. At 6 months and 1, 2, 3, 4, and 5 years postoperatively, the width (horizontal length) and thickness (distance perpendicular to skin) of the FDFG on computed tomography (CT) scans were measured. Histologic samples from the implanted FDFG were collected by core needle biopsy (CNB). The correlations between clinical findings and volume of the FDFG on CT and the proportion of fatty tissue in the CNB were examined statistically. Cosmetic results were also evaluated. RESULTS On CT, the mean width of the FDFG was 95%, 81%, 79%, 73%, 68%, and 47% and the mean thickness were 125%, 121%, 120%, 115%, 104%, and 103% at 6 months, and 1-5 years postoperatively, respectively. In the CNB samples, the mean fatty tissue distribution was 76%, 63%, and 54% at 1 year, 1-4 years, and >4 years postoperatively, respectively. The percent change in the width of the FDFG at 6 months after the operation displayed a significant negative correlation with the postmenopausal period and a significant positive correlation with the maximum surgical margin. On CT, thickness was negatively correlated with the size of the resected breast tissue, and thickness of the implanted FDFG. No clinicopathologic factors or technical factors were related to FDFG outcome and the proportion of fat tissue in the CNB sample, except for axillary dissection. Nineteen of 21 patients had good to excellent cosmesis. CONCLUSION FDFG implanted into breast defects after partial mastectomy undergo mild resorption and degeneration to fibrous tissue, but most patients have good to excellent cosmesis.

Abstract
An inappropriate skin incision on the breast reduces the cosmetic benefit of breast-conserving surgery (BCS). To improve the cosmetic outcome, we have performed "moving window" operation in which BCS can be performed via a periareolar incision (periareolar approach) and/or axillary incision (axillary approach) under direct visualization. Axillary lymph node dissection is also performed via an axillary incision. The periareolar and axillary approaches were used in 65 and 43 patients, respectively. Average operation time was 130 min in periareolar approach and 131 min in axillary approach. Average blood loss was 37 and 50 ml, respectively. Postoperatively, the surgical margin of breast tissue was histologically confirmed to be negative in 107 (99%) of 108 patients, one patients underwent subsequently reoperation because of positive surgical margin. Fifty-two patients (85%) in periareolar approach and 37 patients (86%) in axillary approach had excellent or good cosmetic results. With a mean follow-up of 36 months, four patients developed in-breast recurrence, but three of them had neoadjuvant chemotherapy before surgery. The moving window operation can improve cosmetic outcome of BCS without compromising oncological safety. Moreover, it can reduce operation time and blood loss in comparison to endoscope-assisted BCS.

Abstract
To investigate whether adjuvant treatment with CMF or tamoxifen predisposes to an unfavorable cosmetic outcome or increased breast morbidity after radiotherapy in breast conservation. Data from 266 patients who entered a randomized breast conservation trial (DBCG-82TM protocol) was analyzed. The patients were treated with lumpectomy and axillary dissection followed by external beam radiotherapy to the residual breast. High-risk patients (n = 94), as well as 31 low-risk patients, received additional radiation to the regional lymph nodes. Adjuvant systemic treatment was given to all high-risk patients: premenopausal patients (n = 67) received eight cycles of CMF intravenously (600/40/600 mg per m2) every fourth week; postmenopausal patients (n = 27) received 30 mg of tamoxifen daily for one year. Clinical assessments included cosmetic outcome, breast fibrosis, skin telangiectasia, and dyspigmentation which were scored on a 4-point categorical scale after median 6.6 years. The observations were analyzed in multivariate logistic regression analysis which included potential risk factors on outcome related to systemic treatment, surgery, radiation technique, tumor, and patient characteristics. In premenopausal patients, systemic treatment with CMF independently predicted a fair/poor cosmetic outcome, RR = 2.2 (95% CI 1.2-4.2), as well as increased skin telangiectasia, RR = 3.3 (1.4-8.2). There was no impact of tamoxifen treatment on cosmetic outcome in postmenopausal patients (p = 0.32). However, univariate analysis showed that tamoxifen was significantly associated with breast fibrosis (p < 0.004), as was radiation to the regional lymph nodes (p < 0.0001). A strong interaction between axillary irradiation and tamoxifen treatment occurred since 26 of 27 high-risk postmenopausal patients had received both tamoxifen and axillary irradiation. In multivariate regression analysis, axillary irradiation independently predicted moderate/severe breast fibrosis with a relative risk of 5.0 (2.0-12.5) and 9.6 (3.3-27.7) in premenopausal and postmenopausal patients, respectively. To circumvent the strong interaction between tamoxifen treatment and axillary irradiation, a subsequent analysis omitting axillary treatment from the multivariate regression showed a significant effect of both tamoxifen and CMF on the occurrence of breast fibrosis with relative risks of 5.3 (CI 1.8-15.8) and 4.4 (1.8-10.3), respectively. Adjuvant systemic treatment with CMF given sequentially to radiotherapy independently predicted an adverse cosmetic outcome as well as increased skin telangiectasia after breast conserving treatment. Due to a strong interaction between tamoxifen administration and radiation to the regional lymph nodes, the effect of tamoxifen on the development of fibrosis could not be fully discerned in this study. Axillary irradiation increased the incidence of moderate to severe breast fibrosis in both premenopausal and postmenopausal patients.

Abstract
AIMS To study the influence of various factors affecting cosmetic outcome and late sequelae in a large cohort of women treated with breast-conserving therapy. MATERIALS AND METHODS Between 1980 and 2000, 1022 pathological stage I/II breast cancer patients underwent breast-conserving therapy. On the basis of the type of tumour bed boost they received after whole breast radiotherapy, these women were assigned to three groups: (A) low dose rate (LDR) brachytherapy of 15-20 Gy (n=383); (B) high dose rate (HDR) brachytherapy of 10 Gy (optimised) in a single fraction (n=153); (C) electron beam 15 Gy/six fractions (n=460). Systemic adjuvant therapy was given to 757 women, of whom 570 received adjuvant chemotherapy. RESULTS Cosmesis at the last follow-up was good or excellent in 77% of women. Post-radiation worsening of cosmesis was observed in 11.5% of women and was similar in the three boost groups. Moderate to severe late breast sequelae were observed in 22% of women in group B, which was significantly higher than the 12% in group A (P=0.002) and 9% in group C (P=0.0001). The actuarial 5-year local control rate was 91% and was 90, 92 and 93% in groups A, B and C, respectively. Tumour size (P=0.049) and adjuvant chemotherapy (P=0.04) were the significant factors affecting cosmetic outcome on univariate analysis. On multivariate analysis, adjuvant chemotherapy was the only factor leading to worsening in the cosmetic outcome, with P=0.03 (hazard ratio 1.65 [95% confidence interval 1.05-2.59]). CONCLUSION The type of tumour bed boost did not have a significant effect on the worsening of cosmetic outcome. However, there were significantly more late breast sequelae in women treated with single fraction HDR implants. Chemotherapy had an adverse effect on the cosmetic outcome, but the late breast sequelae and local control rates were comparable.

Abstract
PURPOSE To evaluate the cosmetic results of sequential vs. concurrent adjuvant chemotherapy with radiotherapy after breast-conserving surgery for breast cancer, and to compare ratings by patients and physicians. METHODS AND MATERIALS From 1996 to 2000, 716 patients with Stage I-II breast cancers were included in a multicenter, Phase III trial (the ARCOSEIN study) comparing, after breast-conserving surgery with axillary dissection, sequential treatment with chemotherapy first followed by radiotherapy vs. chemotherapy administered concurrently with radiotherapy. Cosmetic results with regard to both the overall aspect of the breast and specific changes (color, scar) were evaluated in a total of 214 patients (107 in each arm) by means of questionnaires to both the patient and a physician whose rating was blinded to treatment allocation. RESULTS Patients' overall satisfaction with cosmesis was not statistically different between the two arms, with approximately 92% with at least satisfactory results (p = 0.72), although differences between the treated and untreated breasts were greater after the concurrent regimen (29% vs. 14% with more than moderate differences; p = 0.0015). Physician assessment of overall cosmesis was less favorable, with lower rates of at least satisfactory results in the concurrent arm (60% vs. 85%; p = 0.001). Consequently, the concordance for overall satisfaction with cosmesis between patients and doctors was only fair (kappa = 0.62). CONCLUSION After breast-conserving surgery, the concurrent use of chemotherapy with radiotherapy is significantly associated with greater differences between the breasts. These differences do not translate into patients' lessened satisfaction with cosmesis.

Abstract
The aim of this study was to evaluate the factors that determine esthetic outcome after breast cancer conservative treatment, based on a consensual classification obtained with an international consensus panel. Photographs were taken from 120 women submitted to conservative unilateral breast cancer surgery (with or without axillary surgery) and radiotherapy. The images were sent to a panel of observers from 13 different countries and consensus on the classification of esthetic result (recorded as excellent, good, fair or poor) was obtained in 113 cases by means of a Delphi method. For each patient, data were collected retrospectively regarding patient characteristics, tumor, and treatment factors. Univariate and multivariate analysis were used to evaluate the correlation between these factors and overall cosmetic results. On univariate analysis, younger and thinner patients as well as patients with lower body mass index (BMI) and premenopausal status obtained better cosmetic results. In the group of tumor- and treatment-related factors, larger removed specimens, clearly visible scars, the use of chemotherapy and longer follow-up period were associated with less satisfactory results. On multivariate analysis, only BMI and scar visibility maintained a significant association with cosmesis. BMI and scar visibility are the only factors significantly associated with cosmetic results of breast cancer conservative treatment, as evaluated by an international consensus panel.

Abstract
PURPOSE To evaluate the cosmetic outcome of breast conservative therapy and to examine the degree of agreement between the patients' and oncologists' ratings. We also analyze the influence of several factors on cosmesis. METHODS AND MATERIALS We retrospectively evaluated 145 patients with primary breast cancer treated by local excision and radiotherapy between January 2000 and May 2001. Cosmetic outcome was evaluated by doctors and patients and was scored as excellent, good, fair or poor. RESULTS 73% of patients rated cosmesis as excellent or good while the percentage was 71% when rated by radiation oncologists. The degree of cosmesis concordance evaluated by oncologists and patients was low (kappa = 0.3). In our study the variables which significantly influence on the cosmetic outcome were concomitant adjuvant chemotherapy (p = 0.04) and radiation therapy boost, either by electron beam or brachytherapy (p = 0.013). CONCLUSION The cosmetic outcome of breast conserving therapy was good. There was a similar rating by the patient and radiation oncologist, but the level of concordance between patients and doctors was low. Factors that significantly influence the cosmesis appear to be concomitant adjuvant chemotherapy and radiation therapy boost.

Abstract
Women with early stage breast cancer are increasingly being treated with both adjuvant chemotherapy and radiotherapy. The optimal sequence of these two treatment modalities is yet to be defined. It remains controversial whether delaying radiotherapy in order to deliver chemotherapy compromises local disease control and survival. Consequently, clinical practice in the UK is divided, with a number of different combination schedules being used in an effort to bring forward the start of radiotherapy. In practice, however, any benefit in local control must be balanced against a potential increase in toxicity. A review of the current literature on the effect of radiotherapy delay is presented, together with data on the toxicity of combined chemo-radiotherapy schedules and recent data from clinical trials designed to determine the optimal sequencing of chemotherapy and radiotherapy.

Abstract
PURPOSE To compare cosmetic results of two different radiotherapy (RT) boost techniques used in the treatment of breast cancer after whole breast radiotherapy and to identify factors affecting cosmetic outcomes. METHODS AND MATERIALS Between 1996 and 1998, 142 patients with Stage I and II breast cancer were treated with breast conservative surgery and adjuvant RT. Patients were then randomly assigned to receive a boost dose of 15 Gy delivered to the tumor bed either by iridium 192, or a combination of photons and electrons. Cosmetic evaluations were done on a 6-month basis, with a final evaluation at 36 months after RT. The evaluations were done using a panel of global and specific subjective scores, a digitized scoring system using the breast retraction assessment (BRA) measurement, and a patient's self-assessment evaluation. As cosmetic results were graded according to severity, the comparison of boost techniques was done using the ordinal logistic regression model. Adjusted odds ratios (OR) and their 95% confidence intervals (CI) are presented. RESULTS At 36 months of follow-up, there was no significant difference between the two groups with respect to the global subjective cosmetic outcome (OR = 1.40; 95%CI = 0.69-2.85, p = 0.35). Good to excellent scores were observed in 65% of implant patients and 62% of photon/electron patients. At 24 months and beyond, telangiectasia was more severe in the implant group with an OR of 9.64 (95%CI = 4.05-22.92, p < 0.0001) at 36 months. The only variable associated with a worse global cosmetic outcome was the presence of concomitant chemotherapy (OR = 3.87; 95%CI = 1.74-8.62). The BRA value once adjusted for age, concomitant chemotherapy, and boost volume showed a positive association with the boost technique. The BRA value was significantly greater in the implant group (p = 0.03). There was no difference in the patient's final self-assessment score between the two groups. Three variables were statistically associated with an adverse self-evaluation: an inferior quadrant tumor localization, postoperative hematoma, and concomitant chemotherapy. CONCLUSIONS Although this trial showed that at 36 months of follow-up, there were no significant differences in the overall global cosmetic scores between the implant boost group and the photon/electron boost group, telangiectasia was more severe and the BRA value was greater in the implant group.

Abstract
The goals of breast-conserving treatment are to achieve local control and survival rates equivalent to mastectomy and to preserve breast cosmetic appearance. This paper specifically addresses the different ways of cosmetic assessment by the observer (subjective and objective assessments) and by the patient (self-assessment), and the factors which influence the cosmetic outcome, based on a review of the current literature.

Abstract
PURPOSE Radiation pneumonitis and cardiac effects are directly related to the irradiated lung and heart volumes in the treatment fields. The central lung distance (CLD) from a tangential breast radiograph is shown to be a significant indicator of ipsilateral irradiated lung volume. Retrospective analysis of the pattern of dose volume of lung and heart with actual volume data from a CT simulator in the treatment of breast cancer is presented with respect to CLD. METHODS AND MATERIALS The heart and lung volumes in the tangential treatment fields were analyzed in 108 consecutive cases (52 left and 56 right breast) referred for CT simulation. All patients in this study were immobilized and placed on an inclined breast board in actual treatment setup. Both arms were stretched over head to avoid collision with the scanner aperture. Radiopaque marks were placed on the medial and lateral borders of the tangential fields. All patients were scanned in spiral mode with slice width and thickness of 3 mm each, respectively. The lung and heart structures as well as irradiated areas were delineated on each slice and respective volumes were accurately measured. The treatment beam parameters were recorded and the digitally reconstructed radiographs (DRRs) were generated for the measurement of the CLD and analysis. RESULTS Using CT data the mean volume and standard deviation of left and right lungs were 1307.7+/-297.7 cm3 and 1529.6+/-298.5 cm3, respectively. The magnitude of irradiated volume in left and right lung is nearly equal for the same CLD that produces different percent irradiated volumes (PIV). The left and right PIV lungs are 8.3+/-4.7% and 6.6+/-3.7%, respectively. The PIV data have shown to correlate with CLD with second- and third-degree polynomials; however, in this study a simple straight line regression is used to provide better confidence than the higher order polynomials. The regression lines for the left and right breasts are very different based on actual CT data. The slopes of regression lines for the left and right lung are 0.6%/mm and 0.5%/mm, respectively which is statistically different with thep value of 0.01. A maximum heart PIV of >3.0% is observed in 80% of the patients. The heart PIV is inversely correlated with gantry angle and weakly correlated with CLD. CONCLUSIONS The CT-simulator provides accurate volumetric information of the heart and lungs in the treatment fields. The lung PIV is directly correlated to the CLD (0.6%/mm and 0.5%/mm for the left and right lungs). Left and right lungs have different volumes and hence, different regression lines are recommended. An additional 12% lung volume could be irradiated in the supraclavicular field. Heart volume is not correlated with the CLD. The heart PIV is associated to the beam angle. Heart volume may not be accurately visualized in a tangential radiograph; however, this can be easily seen in a DRR with contour delineation and can be minimized with proper beam parameters iteratively with a virtual simulator. Lung and heart PIV along with dose volume histograms (DVH) are essential in reducing pulmonary and cardiac complications.

Abstract
Preventing local recurrence and preserving cosmetic appearance are often in conflict in breast-conserving therapy. Immediate volume replacement with autogenous tissue has been developed to allow a wider excision without compromising the aesthetic results. A review of the literature regarding immediate volume replacement in breast-conserving therapy has led to the following conclusions. When excision of the skin overlying the tumor is unnecessary, a transverse or lateral incision should be used which allows wide excision and immediate volume replacement with autogenous tissue while minimizing scar morbidity. The options for immediate volume replacement include the latissimus dorsi flap with adipose tissue, the latissimus dorsi myocutaneous flap, and the lateral thoracic adipose tissue flap. The choice of technique depends on the amount and position of the skin, subcutaneous tissue, and breast tissue which must be excised. These procedures can be used to extend the indications for breast-conserving therapy, eliminating the need for mastectomy in selected patients. Future developments in the endoscopic harvesting of flaps may further expand the role of volume replacement.

Abstract
PURPOSE In this study we retrospectively analyzed local control, survival rate and late cosmetic results of women with early breast cancer receiving breast conserving therapy. PATIENTS AND METHODS All patients (1984 through 1992) of the Department of Radio-Oncology (University of Heidelberg), who received breast conserving therapy consisting of conservative surgery followed by radiotherapy, were interviewed and asked to come. Subjective estimation of the cosmetic results of therapy was evaluated by means of a questionnaire. Cosmesis, circumferences and temperatures of different mammary regions were assessed and measured. Side effects and late sequelae were valued by the EORTC/RTOG-score. RESULTS Mean follow-up time of 192 women (pT1: 71.9%, pT2: 28.1%) was 4.5 years (median: 4.0 years). 26.6% of them were nodal positive. Positive nodal status correlated with high tumor grading (p = 0.0001). Ten patients developed distant metastases; one of them subsequent to having suffered a loco-regional failure. Eight loco-regional failures occurred, 3 of them before radiotherapy (salvage). Following radiotherapy altogether 5 loco-regional failures (= 2.6%) were found; 3 women concerning were pre-, 2 postmenopausal. Three of these patients died, in 1 case occurred distant metastasis. Seventeen patients died, 3 of them presenting loco-regional failure, 8 of them showing distant metastasis. Sixty-four women were examined for cosmesis with the following result: a poor result was observed twice, a fair result 13 times, a good result 34 and an excellent result 15 times. Self-assessment was significantly better than observer's assessment. Third-degree late sequelae were found once, second-degree was seen 11 times, first-degree 38 times and no visible late sequelae were observed 14 times. The use of wedges was followed with borderline significance (p = 0.06) either by a better cosmesis and fewer late sequelae. Neither the type of surgery nor the width of the fields nor the quality of radiation (Co60 or 6 MVX) nor boost-application influenced the cosmetic result. Measured circumferences and distances showed no significant differences in the groups of the patients with poor or fair and good or excellent cosmesis. The temperature of the seized and contralateral breast showed no significant difference as well. With increasing distance from primary therapy the cosmetic results deteriorated. CONCLUSION Breast conserving therapy consisting of conservative surgery followed by radiotherapy causes predominantly excellent to good cosmetic results combined with an acceptable amount of late side effects. The decreased rate of good and excellent cosmetic long-term results is biological interesting and requires further studies.

Abstract
PURPOSE Although the clinical outcome after treatment of ductal carcinoma in situ (DCIS) using breast-conservation surgery and radiation therapy has been well documented, little data has been reported on cosmetic outcome or treatment complications. Therefore, the present study was performed to evaluate cosmesis and complications after breast-conservation treatment for DCIS and to analyze various factors that might affect cosmesis and predispose to complications. METHODS AND MATERIALS The records of 90 patients who were alive without evidence of disease with a 3-year minimum follow-up were evaluated for cosmetic results and treatment complications following breast-conservation surgery and radiation therapy for DCIS. Complete gross excision of the primary tumor had been performed in all patients. Additionally, 24 patients had undergone an axillary lymph node dissection in the earlier years of the study. The majority of the patients had received 50-50.4 Gy to the whole breast followed by an electron boost for a total dose of 60-66 Gy. RESULTS The cosmetic results of 90 evaluable patients at 3 years were: excellent in 69 (77%), good in 19 (21%), and fair in 2 (2%). The cosmetic results of 64 evaluable patients at 5 years were: excellent in 46 (72%), good in 16 (25%), and fair in 2 (3%). Factors associated with worse cosmetic results were an increased volume of tissue excised (>70 cm3) and a negative ipsilateral breast biopsy after radiotherapy. Complications in the 24 patients with an axillary dissection were: arm edema (n = 6), cellulitis of the arm (n = 5), and axillary vein thrombosis (n = 1). Complications in the 66 patients without an axillary dissection were: cellulitis of the arm (n = 1) and cellulitis of the breast (n = 1). DISCUSSION Breast-conservation surgery followed by radiation therapy achieved excellent or good cosmetic results in 98 and 97% of patients at 3 years and 5 years, respectively. Complications were associated primarily with axillary dissection, which is no longer standard practice, and complications were uncommon in patients without an axillary dissection. Therefore, patients currently treated for DCIS of the breast would be expected to have a high rate of excellent or good cosmetic outcome with a low risk of complications.

Abstract
PURPOSE Chemotherapy plays an increasingly important role in the treatment of both node-negative and node-positive breast cancer patients, but the optimal sequencing of chemotherapy and radiation therapy is not well established. The purpose of this study is to evaluate the interaction of sequence and type of chemotherapy and hormonal therapy given with radiation therapy on the cosmetic outcome and the incidence of complications of Stage I and II breast cancer patients treated with breast-conserving therapy. METHODS AND MATERIALS The records of 1053 Stage I and II breast cancer patients treated with curative intent with breast-conserving surgery, axillary dissection, and radiation therapy between 1977-1991 were reviewed. Median follow-up after treatment was 6.7 years. Two hundred fourteen patients received chemotherapy alone, 141 patients received hormonal therapy alone, 86 patients received both, and 612 patients received no adjuvant therapy. Patients who received chemotherapy +/- hormonal therapy were grouped according to sequence of chemotherapy: (a) concurrent = concurrent chemotherapy with radiation therapy followed by chemotherapy; (b) sequential = radiation followed by chemotherapy or chemotherapy followed by radiation; and (c) sandwich = chemotherapy followed by concurrent chemotherapy and radiation followed by chemotherapy. Compared to node negative patients, node-positive patients more commonly received chemotherapy (77 vs. 9%, p < 0.0001) and/or hormonal therapy (40 vs. 14%, p < 0.0001). Among patients who received chemotherapy, the majority (243 patients) received concurrent chemotherapy and radiation therapy with two cycles of cytoxan and 5-fluorouracil (5-FU) administered during radiation followed by six cycles of chemotherapy with cytoxan, 5-fluorouracil and either methotrexate (CMF) or doxorubicin(CAF). For analysis of cosmesis, patients included were relapse free with 3 years minimum follow-up. RESULTS The use of chemotherapy had an adverse effect on cosmetic outcome compared to no chemotherapy, which was of borderline significance at 3 years (92% excellent or good cosmetic outcome vs. 96% respectively, p = 0.057); however, cosmesis was not different at 5 years (91 vs. 93% respectively, p = 0.67). Cosmesis was not significantly different between patients treated sequentially and those treated concurrently (3 year: 87 vs. 93% respectively, p = 0.33), nor was it different between patients who received CMF vs. CAF (3 year: 92 vs. 93% respectively, p = 0.89). Hormonal therapy did not influence cosmetic outcome (p = 0.78). The incidence of Grade 4 or 5 arm edema (> or = 2 cm difference in arm circumference) was 2% without chemotherapy vs. 8% with chemotherapy (p = 0.00002). However, the incidence of arm edema was not affected by sequencing or type of chemotherapy (all p > or = 0.52). Patients treated sequentially had a 10% incidence of Grade 4 or 5 arm edema vs. 7% in the patients treated concurrently (p = 0.52). The incidence was 7 vs. 9% in patients treated with CMF vs. CAF (p = 0.73). The incidence of clinical pneumonitis and rib fracture was not influenced by use of chemotherapy, sequence of chemotherapy or use of hormonal therapy (all p > or = 0.06). CONCLUSIONS Chemotherapy can be given concurrently with radiation therapy in the treatment of Stage I and II breast cancer with breast-conserving therapy without seriously compromising cosmetic outcome or incidence of complications compared to patients receiving other sequences of chemotherapy. Hormonal therapy did not affect cosmesis or complications. The chemotherapeutic regimen of cytoxan and 5-FU concurrent with radiation therapy followed by more chemotherapy is one reasonable option for breast conservation therapy in patients requiring chemotherapy.

Abstract
One hundred and ninety-seven patients with early stage breast cancer, who were treated initially with conservative surgery, were evaluated prospectively for acute toxicity after completing post-operative irradiation. Eighty-seven of these patients had synchronous chemotherapy with the 3M regimen (mitoxantrone, methotrexate and Mitomycin-C) during radiotherapy. The results indicate that patients receiving chemotherapy and radiotherapy (CRT) showed no significant difference in acute skin toxicity (AST) when compared with those treated with radiotherapy alone (RTO), with an odds ratio (OR = 0.6) and 95% confidence intervals (0.3-1.1) of developing either a moderate or severe, compared with a mild, skin reaction. Even after controlling for other confounding factors, such as treatment technique and beam energy, patients treated with the supine technique using 6-10 MV photons still displayed no significant difference in AST, with 12/74 (16%) patients in the CRT group and 14/66 (21%) in the RTO group developing a moderate or severe skin reaction (OR = 0.7 (95% CI 0.3-1.7)). Four of the 87 patients treated with CRT developed symptomatic acute radiation pneumonitis, three of whom were found to have > 3 cm of lung length on their simulator or check films. The volume of lung included within the treatment field was found to be statistically significant (P = 0.005) in predicting the onset of radiation pneumonitis in the CRT group. None of these patients has suffered any symptomatic late lung toxicity. We conclude that synchronous chemotherapy and radiotherapy, when using the 3M regimen, is feasible for patients having adjuvant treatment for early stage breast carcinoma and there is no significant increase in AST. However, it is associated with an increase in acute radiation pneumonitis when a significant volume of lung is included within the radiation treatment field.

Abstract
PURPOSE Host, tumor, and treatment-related factors influencing cosmetic outcome are analyzed for patients receiving breast conservation treatment. METHODS AND MATERIALS Four-hundred and fifty-eight patients with evaluable records for cosmesis evaluation, a subset of 701 patients treated for invasive breast cancer with conservation technique between 1969 and 1990, were prospectively analyzed. In 243 patients, cosmetic evaluation was not adequately recorded. Cosmesis evaluation was carried out from 3.7 months to 22.3 years, median of 4.4 years. By pathologic stage, tumors were 62% T1N0, 14% T1N1, 15%, T2N0, and 9% T2N1. The majority of patients were treated with 4-6 MV photons. Cosmetic evaluation was rated by both patient and physician every 4-6 months. A logistic regression analysis was completed using a stepwise logistic regression. P-values of 0.05 or less were considered significant. Excellent cosmetic scores were used in all statistical analyses unless otherwise specified. RESULTS At most recent follow-up, 87% of patients and 81% of physicians scored their cosmetic outcome as excellent or good. Eighty-two percent of physician and patient evaluations agreed with excellent-good vs. fair-poor rating categories. Analysis demonstrated a lower proportion of excellent cosmetic scores when related to patient age > 60 years (p = 0.001), postmenopausal status (p = 0.02), black race (p = 0.0034), and T2 tumor size (p = 0.05). Surgical factors of importance were: volume of resection > 100 cm3 (p = 0.0001), scar orientation compliance with the National Surgical Adjuvant Breast Project (NSABP) guidelines (p = 0.0034), and > 20 cm2 skin resected (p = 0.0452). Extent of axillary surgery did not significantly affect breast cosmesis. Radiation factors affecting cosmesis included treatment volume (tangential breast fields only vs. three or more fields) (p = 0.034), whole breast dose in excess of 50 Gy (p = 0.0243), and total dose to tumor site > 65 Gy (p = 0.06), as well as optimum dose distribution with compensating filters (p = 0.002). Daily fraction size of 1.8 Gy vs. 2.0 Gy, boost vs. no boost, type of boost (brachytherapy vs. electrons), total radiation dose, and use of bolus were not significant factors. Use of concomitant chemotherapy with irradiation impaired excellent cosmetic outcome (p = 0.02). Use of sequential chemotherapy or adjuvant tamoxifen did not appear to diminish excellent cosmetic outcomes (p = 0.31). Logistic regression for excellent cosmetic outcome analysis was completed for age, tumor size, menopausal status, race, type of surgery, volume of breast tissue resected, scar orientations, whole breast radiation dose, total radiation dose, number of radiation fields treated, and use of adjuvant chemotherapy. Significant independent factors for excellent cosmetic outcome were: volume of tissue resected (p = 0.0001), type of surgery (p = 0.0001), breast radiation dose (p = 0.005), race (p = 0.002), and age (p = 0.007). CONCLUSIONS Satisfactory cosmesis was recorded in 81% of patients. Impaired cosmetic results are more likely with improper orientation of tylectomy and axillary incisions, larger volume of breast resection, radiation dose to the entire breast in excess of 50.0 Gy, and concurrent administration of chemotherapy. Careful selection of treatment procedures for specific patients/tumors and refinement in surgical/irradiation techniques will enhance the cosmetic results in breast conservation therapy.

Abstract
PURPOSE To establish the toxicity profile of simultaneously administered postoperative radiation therapy and CMF chemotherapy as a prelude to a randomized controlled study addressing the sequencing of the two modalities. METHODS AND MATERIALS One hundred and thirty eight breast cancer patients at high risk of locoregional, as well as systemic relapse, who were referred to three centers in Australia and New Zealand were treated with postoperative radiation therapy and chemotherapy simultaneously. Acute toxicity and dose modifications in these patients were compared with 83 patients treated over the same time frame with chemotherapy alone. In a separate study the long-term radiation and surgical effects in 24 patients treated simultaneously with radiation therapy and chemotherapy at Newcastle (Australia) following conservative surgery were compared with 23 matched patients treated at Newcastle with radiation therapy alone. RESULTS Myelotoxicity was increased in patients treated simultaneously with radiation therapy and chemotherapy. The effect was not great, but may have contributed to chemotherapy dose reductions. Lymphopenia was observed to be the largest factor in total white cell depressions caused by the simultaneous administration of radiation therapy. Postsurgical appearances were found to so dominate long-term treatment effects on the treated breast that the effect of radiation therapy dose and additional chemotherapy was difficult to detect. CONCLUSION Studies addressing the sequencing of radiation therapy and chemotherapy will necessarily be large because adverse effects from administering the two modalities simultaneously are not great. The present study has endorsed the importance in future studies of stratification according to the extent and type of surgery and adherence to a single strict policy of chemotherapy dose modification.

Abstract
PURPOSE To analyze factors involved in the development of fibrosis in the boost area after breast conservation therapy (BCT) in patients treated with continuous low dose rate iridium implants following 50 Gy whole breast irradiation. METHODS AND MATERIALS Fibrosis was estimated by palpation in 404 patients by four physicians. The median follow-up (FUP) duration was 70 months (range 30-133 months). Original implant data were used for reconstruction and dose-volume calculations. The total dose of the external whole breast irradiation and iridium implants was expressed in Normalized Total Dose (NTD): the total dose given in fractions of 2 Gy, which is biologically equivalent to the actual dose given according to the linear-quadratic model, using an alpha/beta value of 2 Gy, and 1.5 h for the recovery half-life of sublethal damage repair. To identify predictors of fibrosis we used a proportional odds model in a polychotomous logistic regression analysis. RESULTS Seven independent factors were identified that were related to the severity of fibrosis: age, duration of FUP, clinical T-size, photon beam energy, NTD level, implant volume, and adjuvant chemotherapy. From the proportional odds model, a volume exponent could be estimated (0.16 +/- 0.04) that enabled us to determine dose-effect relations for different volumes. A 10-fold higher risk of fibrosis was seen when the total dose was above 79 Gy as compared with doses lower than 70 Gy. A fourfold increase in risk of fibrosis was seen for each 100 cm3 increase in irradiated boost volume. The use of adjuvant chemotherapy resulted in a twofold increase in the risk of fibrosis (dose modifying factor approximately 1.08). The application of Co-60 beams had a similar effect. The relative odds for the other factors were smaller (1.4 for each 10 years of older age, and 1.2 for clinical T-size over 20 mm). The FUP-period had a nonlinear effect: relative odds 2.2 at 6 years, 3.6 at 7-8 years, and 2.8 at 9-11 years. The dose rate (mean 0.57, range 0.26-0.89 Gy/h) had no influence on the development of fibrosis and there was no correlation between dose rate and irradiated volume. CONCLUSIONS To optimize cosmetic results after BCT, both the total dose and the irradiated volume should be kept as low as possible. Minimum effective dose levels still have to be established. The boost volume can be minimized by more conformal brachytherapy techniques and optimal localization. It may be worthwhile to take adjuvant chemotherapy into account in decisions on boost dose levels.

Abstract
PURPOSE An alternative technique for irradiating the breast following breast conserving surgery is described. METHODS AND MATERIALS The technique utilizes the prone position and has been developed to improve the dose distribution within the breast and reduce the volume of normal tissues irradiated during whole breast treatment. Improvements in the dosimetry of breast irradiation are obtained through the optimization of the shape of the breast and result in a reduction in the magnitude of high-dose regions and isodose gradients at the base of the breast. RESULTS The high dose region at the base of the breast, without lung correction, generally ranges from 116-118% for large breasted women treated in the supine position. These high dose regions are reduced to 102-103% for the same women treated in the prone position. Irradiation of the heart, lungs, chest wall and contralateral breast are minimized with this technique. The improvements appear to benefit women with large breasts, pendulous breasts, large separations and/or irregularly shaped chest contours. CONCLUSION The prone position technique takes advantage of the reproducibility characteristics of the supine position technique and combines them with the homogeneity and normal tissue-sparing characteristics of the lateral decubitus position technique. Prone position breast irradiation appears to be a simple and effective alternative to irradiation of the breast in the conventional supine position when the supine position is likely to result in unacceptable dose inhomogeneity or significant doses to normal tissues.

Abstract
In a randomised trial, the cosmetic results after sector resection and axillary dissection with or without postoperative radiotherapy for early breast cancer were evaluated. The evaluations were made at 3, 12, 24 and 36 months (357, 326, 302 and 255 women, respectively) after treatment. Good to excellent cosmetic results were achieved in 84-90% of those in the group randomised to radiation and in 91-95% in the group allocated to surgery only, as judged by the women themselves, and in 81-86% and 87-93%, respectively, according to other observers. At 12 months the results in 290 patients were photographically documented and evaluated by a panel. The results were good to excellent in 35-84% of the irradiated group and in 62-93% of the non-irradiated group. Poor results followed the development of contour differences, breast oedema and mamillary deviation, which were the most important mediators of a poor cosmetic result after radiotherapy. We conclude that sector resection and axillary dissection can be performed with good cosmetic results. Doses to 54 Gy of radiotherapy influence the result negatively, but from a clinical standpoint to a moderate extent.

Abstract
To assess the cosmetic results in relation to treatment technique, we retrospectively reviewed the results for 1159 Stage I-II breast cancer patients treated with conservative surgery and radiotherapy between 1970-1985. All patients underwent gross excision followed by radiation therapy including an implant or electron beam boost. The total dose to the primary site was greater than or equal to 60 Gy. Because of technical modifications introduced over time after 1981, the population was divided arbitrarily into two cohorts: 504 patients treated through 1981 and 655 treated between 1982-1985. Median follow-up time for surviving patients in the two cohorts were 107 months and 67 months, respectively. Cosmetic outcome was evaluated by the examining physician and scored as excellent, good, fair or poor. Excellent results at 5 years were scored in 59% of early cohort patients and 74% of the latter cohort (p = 0.002). Acceptable results (either good or excellent) were seen in 84% and 94%, respectively (p = 0.02). In the latter cohort, the likelihood of achieving an excellent result, but not an acceptable result, was significantly related to the volume of resected breast tissue and the use of chemotherapy. The number of fields (three-field technique, provided that fields are precisely matched, compared to tangents only) and boost type (implant vs electrons) did not influence the cosmetic outcome. We conclude that our current technique using breast RT to 45-46 Gy and a boost to the primary site of 16-18 Gy is associated with a high likelihood of acceptable cosmetic results and that this likelihood is not diminished by the use of adjuvant chemotherapy, a large breast resection, the use of a third field, or boost type.

Abstract
148 consecutive patients treated by two different types of conservative surgery were objectively and subjectively evaluated for cosmetic outcome. In 73 patients, tumorectomy, axillary dissection, external radiotherapy (45 Gy) plus iridium implant (15 Gy) were performed, while in the other group of 73 patients a more extensive surgical approach was carried out: quadrantectomy, axillary dissection plus external radiotherapy (50 + 10 Gy). The appearance of the patients' breasts was analysed for symmetry by computer, and differences in symmetry were correlated with tumour location and breast size. A subjective assessment was given by a 3-member panel and the results were correlated with objective measurements. In addition, patients were asked to fill out a self-assessment questionnaire on the aesthetic result of the operated breast. Better results were generally noted in the group of patients treated by more conservative surgery. Substantial differences in the aesthetic outcome were noted between the patient's own evaluation, the computer's measurement of symmetry and the assessment of the panel of observers.

Abstract
Breast cancer is being diagnosed earlier with about 94% of patients presenting with disease limited to the breast or axilla. Despite this trend, more and more patients are receiving adjunctive therapy. In Stage II disease the results of clinical trials suggest that single agent chemotherapy has little if any role in adjuvant therapy. Polychemotherapy can improve survival in premenopausal women with a gain in outcome of about 26%. The duration of therapy appears optimal when given for 6 months. In postmenopausal estrogen receptor-negative women, chemotherapy also has a major role. Tamoxifen appears to offer approximately a 22% improvement in mortality for postmenopausal women. The longer duration of tamoxifen as adjuvant therapy appears to enhance the effect. Premenopausal women may also benefit using tamoxifen but the gain is less clear. Adding tamoxifen to chemotherapy does not enhance the effect. Patients with more than four positive lymph nodes may require more intensive therapy to show a major benefit. Radiotherapy can be integrated along with chemotherapy as adjunctive therapy.

Abstract
The effects of surgical treatment techniques, radiation doses and fraction sizes on cosmetic outcome were analysed in a population of 161 patients with stage I and II breast cancer treated with breast conserving surgery and a wide range of radiotherapy doses. In 142 patients also quantitative measurements of nipple position asymmetries and breast contour retraction were carried out. The scoring and measurement results were analysed using a multivariate model to assess the relative importance of the various factors involved. In this material radiation dose to the breast was the most significant parameter correlated with cosmetic outcome (p = 0.0001). Radiation doses higher than 75 Gy in 37 fractions led to very poor results in more than 30% of patients. For the quantitative measurements of radiation fibrosis, a dose-response curve could be demonstrated over a dose range of 40 to 86 Gy in fraction sizes of 2 Gy. Above 50 Gy, increases in dose of 1 Gy correlated with an average displacement of nipple and breast contour of 1 mm, in upward direction and of 0.75 mm to the median. An increased amount of fibrosis was observed when part of the treatment was given in larger fraction sizes (4-6 Gy). Plotting the data against dose equivalent TE values, an alpha/beta value of 2.5 Gy could be estimated for the development of late fibrosis. Other treatment factors whose influence on cosmetic outcome could be identified and quantified were the differences in surgical techniques for the removal of the primary tumor (tumorectomy vs. segmentectomy, p = 0.05) and for the axillary clearance ("en bloc" dissection vs. separate incisions, p = 0.018). Also technical aspects of the radiotherapy on the regional lymph nodes, sometimes leading to matchline fibrosis, proved to be important (p = 0.0075). Finally, a number of tumor-related factors were assessed in order to take their relative importance into account, if necessary, when studying therapy factors. While tumor stage had only a limited impact in the range of tumors included in this study, the localisation of the tumor significantly influenced cosmetic outcome with worse results for inferior and medial localisations. While quantitative measurements were not correlated with all the factors identified for poor cosmesis, their great value is to quantify the radiation-induced fibrosis as well as the effects of different surgical techniques on nipple retraction.

Abstract
Patients with operable breast cancer were treated at the University of Kansas Medical Center with lumpectomy, peri-operative interstitial Iridium, and external beam radiotherapy, and concomitant adjuvant chemotherapy in a majority of node positive cases. Examination of the cosmetic results in 85 breasts followed for at least 2 years, at a median of 41 months revealed 20% to be excellent, 44% to be very good, 24% good, 9% fair, and 4% to have poor results. In this paper cosmesis is analyzed with reference to the size of the primary, its location, age of the patient, whether the patient received adjuvant chemotherapy, and whether the regional nodes were treated. In this group of patients, the size and the site of the primary, patient's age, and whether adjuvant chemotherapy was administered or not, did not adversely affect the aesthetic outcome. Treatment of the regional nodes gave a worse mean cosmetic score compared to the group in whom only the breast was treated (37.51 vs. 58.98 respectively, p less than 0.001). Among the 11 patients with fair/poor cosmesis, all had regional nodal treatment, 7/11 had inner quadrant lesions, and 7/11 had lesions greater than T1. Further follow-up and accrual would be needed to confirm our results and affirm if other factors would change.

Abstract
In 1987 there were estimated to be approximately 130,000 new cases of breast cancer diagnosed in the United States. Presently, about 20-30,000 of these cases are treated with primary radiotherapy, although many more of the 90,000 stage I and II breast cancer cases are eligible for this form of treatment. Appropriate selection must be employed, including the size and site of the primary tumor, the size of the breast, the potential for multifocal disease, and the age of the patient. When proper selection is used, primary radiotherapy for stage I and II disease yields equivalent overall survival and NED survival when compared to traditional mastectomy. The benefit is preservation of the breast with good to excellent cosmesis in the vast majority of patients.

Abstract
Fifty-eight patients conservatively treated for T1 breast cancers are analyzed for cosmetic outcome; 17 had concomitant adjuvant combination chemotherapy (cyclophosphamide, adriamycin, 5 fluorouracil). The results are evaluated by clinical criteria and a quantitative measurement by use of light field projection at 33 months median follow-up. Surgery consisted of lumpectomy and axillary dissection; radiotherapy was given to the breast only except for additional internal mammary irradiation in central and medial lesions. (50 Gy whole breast, 64 Gy electron/photon boost). Questionnaires are used for inquiry on patient experience: 88% of the patients experienced a good to excellent cosmetic outcome. According to the panel only 64% show a good to excellent cosmesis. Panel-scores on asymmetry are compared with quantitative measurements. More esophagitis and probably a higher degree of fibrosis in the boost area is found in the chemotherapy group. No differences in cosmetic outcome, complication rates, and patient experiences are seen. Results are compared with published data.

Abstract
High-energy irradiation is used increasingly as a part of breast conservation treatment of malignant disease. The response of the breast tissue encompassed by the treatment fields varies considerably, even in well-conducted therapeutic programs. Early and late changes in the tissues include redness, edema, pigmentation, fibrosis, and retraction. Fibrosis and retraction may cause suboptimal cosmetic results and occur most frequently in obese patients, large breasts, and breasts from which a large (greater than 4 cm) primary tumor has been excised. Combinations of treatment modalities, such as adjuvant chemotherapy, surgical excision, and irradiation, seem to produce fewer excellent cosmetic results than single-modality treatment. In patients who have undergone breast conservation treatment, careful follow-up is necessary for detection of possible local, regional, or distant recurrence of the malignant disease, as well as of other diseases related or unrelated to the earlier treatment.
