Patient self-evaluation of cosmetic outcome of breast-preserving cancer treatment

A Novel, Deep Learning-Based, Automatic Photometric Analysis Software for Breast Aesthetic Scoring

Background  Breast aesthetics evaluation often relies on subjective assessments, leading to the need for objective, automated tools. We developed the Seoul Breast Esthetic Scoring Tool (S-BEST), a photometric analysis software that utilizes a DenseNet-264 deep learning model to automatically evaluate breast landmarks and asymmetry indices. Methods  S-BEST was trained on a dataset of frontal breast photographs annotated with 30 specific landmarks, divided into an 80-20 training-validation split. The software requires the distances of sternal notch to nipple or nipple-to-nipple as input and performs image preprocessing steps, including ratio correction and 8-bit normalization. Breast asymmetry indices and centimeter-based measurements are provided as the output. The accuracy of S-BEST was validated using a paired t -test and Bland-Altman plots, comparing its measurements to those obtained from physical examinations of 100 females diagnosed with breast cancer. Results  S-BEST demonstrated high accuracy in automatic landmark localization, with most distances showing no statistically significant difference compared with physical measurements. However, the nipple to inframammary fold distance showed a significant bias, with a coefficient of determination ranging from 0.3787 to 0.4234 for the left and right sides, respectively. Conclusion  S-BEST provides a fast, reliable, and automated approach for breast aesthetic evaluation based on 2D frontal photographs. While limited by its inability to capture volumetric attributes or multiple viewpoints, it serves as an accessible tool for both clinical and research applications.

Methods of Esthetic Assessment after Adjuvant Whole-Breast Radiotherapy in Breast Cancer Patients: Evaluation of the BCCT.core Software and Patients' and Physicians' Assessment from the Randomized IMRT-MC2 Trial

Simple Summary

To validate the BCCT.core software, the present analysis compares the esthetics assessment by the software in relation to patients’ and physicians’ rating in breast cancer patients after surgery and adjuvant radiotherapy. Agreement rates of the different assessments and their correlation with breast asymmetry indices were evaluated. The assessments of the software and the physicians were significantly correlated with all asymmetry indices, while for patients’ self-assessment, this general correlation was first seen after 2 years. Only a slight agreement between the BCCT.core software and the physicians’ or patients’ assessment was seen, while a moderate and substantial agreement was detected between the physicians’ and the patients’ assessments. The BCCT.core software is a reliable tool to measure asymmetries, but may not sufficiently evaluate the esthetic outcome as perceived by patients. It may be more appropriate for a long-term follow-up, when symmetry seems to increase in importance.

Abstract

The present analysis compares the esthetics assessment by the BCCT.core software in relation to patients’ and physicians’ ratings, based on the IMRT-MC2 trial. Within this trial, breast cancer patients received breast-conserving surgery (BCS) and adjuvant radiotherapy. At the baseline, 6 weeks, and 2 years after radiotherapy, photos of the breasts were assessed by the software and patients’ and physicians’ assessments were performed. Agreement rates of the assessments and their correlation with breast asymmetry indices were evaluated. The assessments of the software and the physicians were significantly correlated with asymmetry indices. Before and 6 weeks after radiotherapy, the patients’ self-assessment was only correlated with the lower breast contour (LBC) and upward nipple retraction (UNR), while after 2 years, there was also a correlation with other indices. Only a slight agreement between the BCCT.core software and the physicians’ or patients’ assessment was seen, while a moderate and substantial agreement was detected between the physicians’ and the patients’ assessment after 6 weeks and 2 years, respectively. The BCCT.core software is a reliable tool to measure asymmetries, but may not sufficiently evaluate the esthetic outcome as perceived by patients. It may be more appropriate for a long-term follow-up, when symmetry appears to increase in importance.

Oncoplastic Breast Reconstruction in Breast Conservation Surgery: Improving the Oncological and Aesthetic Outcomes

Breast conservation surgery (BCS) is now the standard of care for patients with early breast cancer. The main contraindications for BCS besides the presence of multicentricity and diffuse microcalcifications are inadequate tumour size to breast size ratio. With the advent of oncoplastic techniques, the indications of BCS may be further extended to patient with larger tumour size and or small volume breast. We prospectively assessed 42 patients undergoing oncoplastic breast conservation surgery for cosmetic and oncologic outcomes. Cosmetic outcome assessment was done by comparison of operated breast to contralateral breast by an independent surgeon, nurse and patient's attendant at 6 months post-surgery. Risk factors for compromised oncologic outcomes included grades II/III tumours and non-ductal histology. Intraoperative margin assessment with frozen section analysis proved to be important in order to achieve negative surgical margins on final histopathology. By univariate analysis, tumours located in central quadrant and medial half of the breast had similar cosmetic outcomes comparable to tumours located in other quadrants. Majority of our patients (90%) had overall good to excellent cosmetic outcomes on Harvard scale. Oncoplastic breast conservation surgery techniques allow for larger parenchymal resections without compromising oncologic and cosmetic results. It further allows extension of BCS to patients otherwise denied for the same based on earlier recommendations for mastectomy. Oncoplastic techniques and intraoperative margin assessment with frozen section are vital in attaining adequate margins and also decrease chance of local recurrence and revision surgery for positive margins.

Evaluation of the effect of the accordion suturing technique on wound lengths in breast cancer surgery: a randomised clinical trial

BACKGROUND

Cosmetic outcomes and scar lengths remain important considerations in breast cancer surgery. Suturing techniques should decrease scar tissue formation and provide good cosmetic results. The use of an accordion suturing technique may result in decreased surgical wound lengths and better cosmetic outcomes. We compared the outcomes of the accordion suturing technique with the standard suturing technique in breast cancer surgeries.

MATERIALS AND METHODS

Female patients undergoing wide local excision of breast cancers were randomised to undergo closure of their surgical wound by either the accordion or the non-accordion (standard) suturing techniques between the months of May and October 2015. Pre-closure and post-closure wound lengths were measured intra-operatively. The primary outcome was a reduction of the surgical wound length at 6 weeks. The secondary outcome was a composite of the absence of hypertrophic scar tissue formation and optimal cosmesis.

RESULTS

Thirty eligible women for wide local excision of breast tumours were randomly assigned to the accordion and non-accordion groups (15 accordion and 15 non-accordion). Seven women were excluded from the study because they underwent re-excision of margins for their breast tumours before the end of 6 weeks, and one woman was lost to follow-up. We therefore compared the outcomes of 12 women who underwent closure of their surgical wound by way of the accordion suturing technique to the outcomes of 10 women who underwent closure with the non-accordion (standard) suturing technique. The percentage reduction of wound length at 6 weeks was significantly greater in the accordion group than in the non-accordion group (M = 24.4, SD = 10.2 vs. M = 8.6, SD = 11.5, p = 0.0026). There was no significant difference in the cosmetic outcome between both groups using the James Quinn's wound evaluation score.

CONCLUSION

The accordion suturing technique was associated with a significant reduction in surgical wound lengths in breast conserving surgery at 6 weeks without compromising the cosmetic result.

Breast-specific factors determine cosmetic outcome and patient satisfaction after breast-conserving therapy: Results from the randomized COBALT study

BACKGROUND AND OBJECTIVES

To identify breast-specific factors and the role of tumor, treatment, and patient-related items in influencing patient opinion on cosmesis and satisfaction after breast-conserving therapy (BCT).

METHODS

Data from the randomized COBALT study was used. At 3, 12, and 36 months, 128 patients with T1-T2 breast cancer completed a questionnaire on breast-specific factors and overall cosmetic outcome and patient satisfaction, using a 4-point Likert scale.

RESULTS

There was a strong positive correlation between breast-specific factors, overall cosmetic outcome,and satisfaction at all time-points. Excellent/good cosmetic outcomes and satisfaction decreased during follow-up. A shift was noted in the degree of influence of the various breast-specific factors. At 3 years, symmetry factors such as size, shape, and nipple position largely determined a patient's opinion on the final cosmesis, followed by firmness. The risk of an unacceptable outcome was associated with young age and large excision volumes.

CONCLUSION

A questionnaire including breast-specific questions provides important information on final cosmetic results and satisfaction after BCT. These outcomes can also be of great value as quality indicators and pre-operative counseling. The major influence of breast-specific factors on asymmetry underlines the importance of achieving an optimal excision volume at the initial procedure.

Oncoplastic Surgery for Upper/Upper Inner Quadrant Breast Cancer

Tumors located in the upper/upper inner quadrant of the breast warrant more attention. A small lesion relative to the size of breast in this location may be resolved by performing a level I oncoplastic technique. However, a wide excision may significantly reduce the overall quality of the breast shape by distorting the visible breast line. From June 2012 to April 2015, 36 patients with breast cancer located in the upper/upper inner quadrant underwent breast-conservation surgery with matrix rotation mammoplasty. According to the size and location of the tumor relative to the nipple-areola complex, 11 patients underwent matrix rotation with periareolar de-epithelialization (donut group) and the other 25 underwent matrix rotation only (non-donut group). The cosmetic results were self-assessed by questionnaires. The average weights of the excised breast lumps in the donut and non-donut groups were 104.1 and 84.5 g, respectively. During the 3-year follow-up period, local recurrence was observed in one case and was managed with nipple-sparing mastectomy followed by breast reconstruction with prosthetic implants. In total, 31 patients (88.6%) ranked their postoperative result as either acceptable or satisfactory. The treated breasts were also self-evaluated by 27 patients (77.1%) to be nearly identical to or just slightly different from the untreated side. Matrix rotation is an easy breast-preserving technique for treating breast cancer located in the upper/upper inner quadrant of the breast that requires a relatively wide excision. With this technique, a larger breast tumor could be removed without compromising the breast appearance.

Clinimetric properties and clinical utility in rehabilitation of postsurgical scar rating scales: a systematic review

The aim of this study was to review and critically assess the most used and clinimetrically sound outcome measures currently available for postsurgical scar assessment in rehabilitation. We performed a systematic review of the Medline and Embase databases to June 2015. All published peer-reviewed studies referring to the development, validation, or clinical use of scales or questionnaires in patients with linear scars were screened. Of 922 articles initially identified in the literature search, 48 full-text articles were retrieved for assessment. Of these, 16 fulfilled the inclusion criteria for data collection. Data were collected pertaining to instrument item domains, validity, reliability, and Rasch analysis. The eight outcome measures identified were as follows: Vancouver Scar Scale, Dermatology Life Quality Index, Manchester Scar Scale, Patient and Observer Scar Assessment Scale, Bock Quality of Life (Bock QoL) questionnaire, Stony Brook Scar Evaluation Scale, Patient-Reported Impact of Scars Measure, and Patient Scar Assessment Questionnaire. Scales were examined for their clinimetric properties, and recommendations for their clinical or research use and selection were made. There is currently no absolute gold standard to be used in rehabilitation for the assessment of postsurgical scars, although the Patient and Observer Scar Assessment Scale and the Patient-Reported Impact of Scars Measure emerged as the most robust scales.

The Cambridge Breast Intensity-modulated Radiotherapy Trial: Comparison of Clinician- versus Patient-reported Outcomes

AIMS

Breast radiotherapy-associated toxicity is often reported using clinical and photographic assessments. The addition of patient-reported outcome measures (PROMs) is becoming more common. This study investigated the concordance between clinician- and patient-reported outcomes.

MATERIALS AND METHODS

The Cambridge Breast Intensity-modulated Radiotherapy (IMRT) trial prospectively collected data on clinician assessment and PROMs at 2 and 5 years after breast radiotherapy. Clinician assessment included physical examination and photographic assessment. PROMs included European Organization for Research and Treatment of Cancer (EORTC) BR23 questionnaire and four breast radiotherapy-specific questions. The correlation between patient and clinician scores were analysed on an independent patient basis using percentage agreement, Cohen's kappa coefficient (k) and Bowker's test of symmetry. The analysis was repeated after stratifying patients based on age, baseline Hospital Anxiety and Depression Score (HADS) and baseline body image score.

RESULTS

At 2 and 5 years, a weak level of concordance was seen between the clinician-based assessment and PROMS for all the five toxicity end points (k = 0.05-0.21), with individual patient-based agreement of 32.9-78.3% and a highly discordant Bowker's test of symmetry (P < 0.001). The most frequently reported moderate-severe toxicity by patients was change in breast appearance (14% at both 2 and 5 years), whereas it was breast induration (36% and 25% at 2 and 5 years, respectively) by the clinicians. The lack of concordance was not affected by patient's age, baseline HADS and baseline body image score.

CONCLUSIONS

This study found that moderate-severe toxicity reported by patients is low and the overall concordance between clinicians and patients is low. This could be due to methodological limitations or alternatively reflects the subjective nature of PROMs. Incorporation of a patient's perception on treatment-related toxicity will have important implications for treatment decisions and follow-up care.

Dermoglandular rotation flaps for breast-conserving therapy: aesthetic results, patient satisfaction, and morbidity in comparison to standard segmentectomy

We compared a dermoglandular rotation flap (DGR) in the upper inner, lower inner, and upper outer quadrant regarding similar aesthetic results, patient satisfaction, and comfort after breast-conserving therapy with standard segmentectomy (SE). Between 2003 and 2011, 69 patients were treated with breast-conserving surgery using DGR for cancers with high tumor-to-breast volume ratios or skin resection in the three above mentioned quadrants; 161 patients with tumors in the same quadrants were treated with SE. The outcome of the procedures was assessed at least 7 months after completed radiation therapy using a patient and breast surgeon questionnaire and the BCCT.core software. Symmetry, visibility of the scars, the position of the nipple-areola complex, and the appearance of the treated breast were each assessed on a scale from 1 to 4 by an expert panel and by the patients. Univariate and multivariate analysis were used to evaluate the relationship between patient-, tumor-, and treatment-dependent factors and patient satisfaction. 94.2% of the patients with rotation flaps and 83.5% of the patients with lumpectomy were very satisfied with the cosmetic appearance of their breast. Younger patient age was significantly associated with a lower degree of satisfaction. DGR provides good cosmetic results compared with SE and shows high patient satisfaction despite longer scarring and higher median resection volume.

The impact of breast cosmetic and functional outcomes on quality of life: long-term results from the St. George and Wollongong randomized breast boost trial

The aims of this study were to evaluate the impact of cosmetic and functional outcomes after breast-conserving surgery (BCS) and radiation on quality of life (QOL). In this exploratory analysis; baseline, 5 and 10 years data of patient's assessment of breast cosmesis, arm swelling/pain, limitation of movement, loss of feeling in fingers and breast sensitivity/tenderness were dichotomized and their impact on QOL (QLQ-C30) were assessed. Multivariable modelling was also performed to assess associations with QOL. The St. George and Wollongong randomized trial randomized 688 patients into the boost and no boost arms. 609, 580, and 428 patients had baseline, 5 and 10 years cosmetic data available, respectively. Similar numbers had the various functional assessments in the corresponding period. By univariate analysis, cosmesis and a number of functional outcomes were highly associated with QOL. Adjusted multivariate modelling showed that cosmesis remained associated with QOL at 5 and 10 years. Breast sensitivity, arm pain, breast separation, age and any distant cancer event were also associated with QOL on multivariate modelling at 10 years. This study highlights the importance of maintaining favorable cosmetic and functional outcomes following BCS. In addition, the clinically and statistically significant relationship between functional outcomes and QOL shows the importance for clinicians and allied health professionals in identifying, discussing, managing, and limiting these effects in women with breast cancer in order to maintain QOL.

A prospective study of breast lymphedema: frequency, symptoms, and quality of life

Although lymphedema of the arm is a well-known complication of breast and axillary surgery, breast lymphedema has received scant attention. We sought to prospectively characterize breast lymphedema's incidence, associated symptoms, clinical course, and impact on quality of life. Subjects were enrolled prospectively from a consecutive sample of patients undergoing non-mastectomy breast procedures (excisional biopsy or wide local excision ± lymph node removal) and followed for signs and symptoms of lymphedema in the operated breast. Symptoms and distress were serially assessed with 11-point linear analog scales. Breast lymphedema was diagnosed independent of symptoms, based on the distribution and degree of edema and erythema. One hundred twenty-four women were followed for a median of 11 months, and breast lymphedema was diagnosed in 38 (31%) women. Breast lymphedema was more frequent after breast surgery with axillary node removal (49%) compared to breast surgery alone (0%), p < 0.0001. Breast lymphedema involved multiple quadrants in most women and was characterized by edema in 100% and erythema in 79%. Patients with breast lymphedema were significantly more likely than women without breast lymphedema to report symptoms of breast heaviness (65% vs 22%, p < 0.0001), redness (62% vs 29%, p = 0.0006), and swelling (59% vs 22%, p < 0.0001), but symptom-associated distress was low overall. Three of 32 breast lymphedema patients with clinical follow-up developed chronic edema. Breast lymphedema occurs in approximately one-half of women who undergo breast surgery with axillary node removal. The condition is characterized by diffuse skin edema and erythema as well as self-reported symptoms with a low level of distress.

Radiotherapy breast boost with reduced whole-breast dose is associated with improved cosmesis: the results of a comprehensive assessment from the St. George and Wollongong randomized breast boost trial

PURPOSE

To evaluate comprehensively the effect of a radiotherapy boost on breast cosmetic outcomes after 5 years in patients treated with breast-conserving surgery.

METHODS

The St. George and Wollongong trial (NCT00138814) randomized 688 patients with histologically proven Tis-2, N 0-1, M0 carcinoma to the control arm of 50 Gy in 25 fractions (342 patients) and the boost arm of 45 Gy in 25 fractions to the whole breast followed by a 16 Gy in 8 fraction electron boost (346 patients). Five-year cosmetic outcomes were assessed by a panel subjectively in 385 patients and objectively using pBRA (relative breast retraction assessment). A subset of patients also had absolute BRA measurements. Clinician assessment and patient self-assessment of overall cosmetic and specific items as well as computer BCCT.core analysis were also performed.

RESULTS

The boost arm had improved cosmetic overall outcomes as scored by the panel and BCCT.core software with 79% (p = 0.016) and 81% (p = 0.004) excellent/good cosmesis respectively compared with 68% in no-boost arm. The boost arm also had lower pBRA and BRA values with a mean difference of 0.60 and 1.82 mm, respectively, but was not statistically significant. There was a very high proportion of overall excellent/good cosmetic outcome in 95% and 93% in the boost and no-boost arms using patient self-assessment. However, no difference in overall and specific items scored by clinician assessment and patient self-assessment was found.

CONCLUSION

The results show the negative cosmetic effect of a 16-Gy boost is offset by a lower whole-breast dose of 45 Gy.

How to assess postsurgical scars: a review of outcome measures

PURPOSE

Complications of surgical incision include pathological scars with functional, cosmetic or psychological consequences. Postsurgical scar assessment is fundamental for a complete functional evaluation and as an outcome measure. Scar assessment scales are here reviewed and discussed from a clinical and psychometric point of view, with a clear definition of different scar parameters.

METHOD

An extensive review of the English-language literature was conducted using the Medline database.

RESULTS

Four scales that satisfy psychometrical criteria were identified: Vancouver Scar Scale (VSS), Patient and Observer Scar Assessment Scale (POSAS), Manchester Scar Scale (MSS) and Stony Brook Scar Evaluation Scale (SBSES).

CONCLUSIONS

To date, VSS is the most widely used rating scale for scars but POSAS appears the most comprehensive, taking into account the important aspect of patient's perspective. The MSS has been never used for research, while SBSES has only been very recently proposed.

Does Concurrent Radiochemotherapy Affect Cosmetic Results in the Adjuvant Setting After Breast-Conserving Surgery? Results of the ARCOSEIN Multicenter, Phase III Study: Patients’ and Doctors’ Views

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.

Factors Determining Esthetic Outcome after Breast Cancer Conservative Treatment

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.

Reliability and validity testing of the Patient and Observer Scar Assessment Scale in evaluating linear scars after breast cancer surgery

BACKGROUND

The Patient and Observer Scar Assessment Scale is a promising new method incorporating observer and patient ratings in evaluating burn scars. The authors compared this tool to the Vancouver Scar Scale in a cohort of women with linear scars from breast cancer surgery.

METHODS

Twenty women with newly diagnosed breast cancer were prospectively accrued. Thirty-one scars were evaluated. The median time from surgery to scar assessment was 8 weeks (range, 3 to 25 weeks). Observer assessment was performed by three independent raters using the Vancouver scale and the observer component of the new tool. Patient self-assessment was performed using the patient component of the tool. Internal consistency, interobserver reliability, and convergent validity were examined.

RESULTS

Internal consistency was acceptable for the Vancouver scale and both components of the new tool (Cronbach's alpha, 0.71, 0.74, and 0.77, respectively). Interobserver reliability was substantial with both the Vancouver scale and the observer tool (average measure intraclass coefficient correlation, 0.78 and 0.60, respectively). The observer tool and Vancouver scale correlated significantly with each other (p < 0.001), but only the observer tool correlated well with patients' ratings (p = 0.04).

CONCLUSIONS

In surgical scar assessment, the new Patient and Observer Scar Assessment Scale and Vancouver Scar Scale were both associated with acceptable internal consistency and interobserver reliability. The new tool is more comprehensive and has higher correlation with patients' ratings. These findings support the use of the new tool as a reliable, valid, and comprehensive approach to assess linear surgical scars.

Cosmetic outcome of breast conservative treatment for early stage breast cancer

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.

Quantitative Analysis of the Reconstructed Breast Using a 3-Dimensional Laser Light Scanner

Postoperative cosmesis of the reconstructed breast depends on the interrelation of shape, size (volume), and symmetry. In this study, reconstructed breasts were analyzed with 3-dimensional projections generated by laser light scanning. Fifty-one cases of breast reconstruction following mastectomy (16 cases of rectus abdominis flap, 15 cases of latissimus dorsi flap, and 20 cases of tissue expansion) were evaluated 6 months postoperatively. Shape, volume, and symmetry were quantitatively evaluated. Captured images of the normal breast were mirror-reversed and superimposed on images of the reconstructed breast. Differences in the generated Moire patterns were used to quantitatively compare breasts. The method was rapid, reproducible, and accurate in comparison to thermoplaster casts. It was found that rectus abdominis flaps applied following total mastectomy and latissimus dorsi flaps applied following partial mastectomy gave the best results for their relatively low degree of asymmetry. Application of tissue expansion led to greater asymmetry and poorer overall cosmesis. In conclusion, a 3-dimensional laser light scanning system makes it possible to quantitate the cosmetic outcome following breast reconstruction.

A cosmetic evaluation of breast cancer treatment: A randomized study of radiotherapy boost technique

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.

Breast-Conserving Therapy in Patients with a Relatively Large (T2 or T3) Breast Cancer: Long-Term Local Control and Cosmetic Outcome of a Feasibility Study

Breast-conserving therapy is widely accepted as an appropriate method of primary treatment of T1 and T2 breast cancers that measure up to 5 cm. For safe and cosmetically acceptable breast-conserving therapy in patients with larger breast cancers, the tumor volume has to be reduced preoperatively, and lost tissue volume should be replaced after wide local excision. In 1993, the authors' group reported encouraging short-term results of a combination of preoperative radiotherapy, breast-conserving surgery, and immediate tissue replacement by myocutaneous (myosubcutaneous) latissimus dorsi flap transplantation in patients with relatively large T2 and T3 breast cancers. To evaluate the long-term oncologic local control and cosmetic outcome of this treatment modality, the authors studied the results obtained in 20 patients after a minimum follow-up of 5 years. The local control rate was 0.95, as locoregional recurrence was observed in one patient who refused adjuvant chemotherapy. Both the observed 5-year survival (0.75) and the actuarial 10-year survival (0.60) in the authors' series equaled that of more radical surgical therapy. The cosmetic outcome compared with that obtained by conventional breast-conserving therapy modalities for small breast cancers. In general, patient assessment of cosmetic outcome (2.8 of 3) was higher than the assessment of a professional panel (6.3 of 10). Of six criteria providing a detailed description of the cosmesis of the reconstructed breast and donor area, the symmetry and shape of the reconstructed breast were felt to be most important by the patients and professionals alike. The authors conclude that breast-conserving therapy combining preoperative irradiation and immediate myocutaneous (myosubcutaneous) latissimus dorsi flap reconstruction is an oncologically safe and cosmetically rewarding but logistically straining modality of treatment of relatively large T2 and T3 breast cancers.

Cosmesis from the patient's and the doctor's view

PURPOSE

Long-term cosmesis from the patient's perspective is compared to the doctor's appraisal. Factors that determine judgment of cosmesis are analyzed. Also, a patient questionnaire was designed to screen for normal tissue reactions and is evaluated.

METHODS AND PATIENTS

With structured questions, patients rated their satisfaction considering cosmesis, the difference in overall appearance, and specific changes of the breast. Two doctors rated cosmesis and radiation late effects (LENT/SOMA). Ratings were compared, and the relative impact of single items was studied. Two hundred eighty-seven patients with unilateral breast carcinoma were examined after a median follow-up of 8 years. They were treated between 1981 and 1995 with lumpectomy and radiotherapy of the breast with 1.8-2.5 Gy fractions with a median total dose of 55 Gy (range: 50-65 Gy).

RESULTS

One hundred sixty-one patients rated cosmesis as satisfying, 73 patients rated it as acceptable, and 25 patients as poor. Eighty-nine patients noted severe changes of appearance. Severe firmness and extensive scars were the most frequent complaint; the most important single item for judging cosmesis as poor was highly visible scars. Generally, doctors rated cosmesis less favorably (satisfactory, 150 patients; poor, 43 patients). Severe fibrosis was more important than discoloration of the breast or scars. Correlation between patients' and doctors' rating of cosmesis was modest (Cohen's weighted kappa 0.29), whereas the doctor's rating correlated well (0.55). Specificity and sensitivity of the questionnaire item for severe fibrosis (using doctors' judgments as gold standard) was 0.8; Cohen's weighted kappa was 0.34 (95% confidence interval: 0.21-0.48).

CONCLUSION

Rating of cosmesis is subjective. Patients' satisfaction with cosmesis is greater than the doctors' and is determined not only by radiation late effects, but also by factors unrelated to the appearance of the breast. Severe fibrosis may be detected by a patient questionnaire.

A shorter fractionation schedule for postlumpectomy breast cancer patients

PURPOSE

The purpose of this retrospective review was to determine the effectiveness of 40 Gy in 16 daily fractions in preventing local recurrence in postlumpectomy invasive breast cancer patients whose margins of resection were clear of tumor by at least 2 mm.

METHODS

Between September 1989 and December 1993, 294 breasts were treated with this regimen. The entire breast was treated, using a tangential parallel pair, with wedges as necessary, to a dose of 40 Gy in 16 daily fractions. No additional boost was given. The median duration of follow-up of surviving patients is 5.5 years. Recently, the patients' assessment of the cosmetic outcome of their treatment was obtained, using a mailed questionnaire.

RESULTS

The 5-year actuarial breast-relapse rate was 3.5%, with an overall 5-year survival and disease-specific survival of 87.8% and 92.1%, respectively. In response to the cosmesis questionnaire, 77% of patients stated they were either extremely or very satisfied with the overall appearance of the breast, 19.5% moderately satisfied, and 3.5% either slightly or not at all satisfied. The corresponding responses for overall level of comfort of the breast were 79%, 16.5%, and 4.5% respectively.

CONCLUSION

This regimen is very effective at preventing recurrent breast cancer in this group of patients, and it provides a high level of patient satisfaction with cosmetic outcome. Its short duration offers the added advantage of a more efficient use of resources and greater patient convenience.

On the use of virtual simulation in radiotherapy of the intact breast

In this paper a method of breast cancer treatment planning using virtual simulation implemented at the Department of Human Oncology at the University of Wisconsin is described. All patients in this procedure are placed in a custom vacuum mold in treatment position with both arms up to avoid collision with the CT scanner aperture. For all patients a CT scan of 5-mm-slice thickness is acquired. The ipsilateral and contralateral breast, the ipsilateral lung and the heart are delineated and a three-dimensional plan is generated that tries to minimize the dose to the ipsilateral lung and heart while ensuring adequate coverage of the affected breast. Digitally reconstructed radiographs are used to verify the patient setup on the treatment machine.

The influence of the boost in breast-conserving therapy on cosmetic outcome in the EORTC "boost versus no boost" trial. EORTC Radiotherapy and Breast Cancer Cooperative Groups. European Organization for Research and Treatment of Cancer

PURPOSE

To evaluate the influence of a radiotherapy boost on the cosmetic outcome after 3 years of follow-up in patients treated with breast-conserving therapy (BCT).

METHODS AND MATERIALS

In EORTC trial 22881/10882, 5569 Stage I and II breast cancer patients were treated with tumorectomy and axillary dissection, followed by tangential irradiation of the breast to a dose of 50 Gy in 5 weeks, at 2 Gy per fraction. Patients having a microscopically complete tumor excision were randomized between no boost and a boost of 16 Gy. The cosmetic outcome was evaluated by a panel, scoring photographs of 731 patients taken soon after surgery and 3 years later, and by digitizer measurements, measuring the displacement of the nipple of 3000 patients postoperatively and of 1141 patients 3 years later.

RESULTS

There was no difference in the cosmetic outcome between the two treatment arms after surgery, before the start of radiotherapy. At 3-year follow-up, both the panel evaluation and the digitizer measurements showed that the boost had a significant adverse effect on the cosmetic result. The panel evaluation at 3 years showed that 86% of patients in the no-boost group had an excellent or good global result, compared to 71% of patients in the boost group (p = 0.0001). The digitizer measurements at 3 years showed a relative breast retraction assessment (pBRA) of 7.6 pBRA in the no-boost group, compared to 8.3 pBRA in the boost group, indicating a worse cosmetic result in the boost group at follow-up (p = 0.04).

CONCLUSIONS

These results showed that a boost dose of 16 Gy had a negative, but limited, impact on the cosmetic outcome after 3 years.

Validation of the methods of cosmetic assessment after breast-conserving therapy in the EORTC "boost versus no boost" trial. EORTC Radiotherapy and Breast Cancer Cooperative Groups. European Organization for Research and Treatment of Cancer

PURPOSE

To evaluate both qualitative and quantitative scoring methods for the cosmetic result after breast-conserving therapy (BCT), and to compare the usefulness and reliability of these methods.

METHODS AND MATERIALS

In EORTC trial 22881/10882, stage I and II breast cancer patients were treated with tumorectomy and axillary dissection. A total of 5318 patients were randomized between no boost and a boost of 16 Gy following whole-breast irradiation of 50 Gy. The cosmetic result was assessed for 731 patients in two ways. A panel scored the qualitative appearance of the breast using photographs taken after surgery and 3 years later. Digitizer measurements of the displacement of the nipple were also made using these photographs in order to calculate the breast retraction assessment (BRA). The cosmetic results after 3-year follow-up were used to analyze the correlation between the panel evaluation and digitizer measurements.

RESULTS

For the panel evaluation the intraobserver agreement for the global cosmetic score as measured by the simple Kappa statistic was 0.42, considered moderate agreement. The multiple Kappa statistic for interobserver agreement for the global cosmetic score was 0.28, considered fair agreement. The specific cosmetic items scored by the panel were all significantly related to the global cosmetic score; breast size and shape influenced the global score most. For the digitizer measurements, the standard deviation from the average value of 30.0 mm was 2.3 mm (7.7%) for the intraobserver variability and 2.6 mm (8.7%) for the interobserver variability. The two methods were significantly, though moderately, correlated; some items scored by the panel were only correlated to the digitizer measurements if the tumor was not located in the inferior quadrant of the breast.

CONCLUSIONS

The intra- and interobserver variability of the digitizer evaluation of cosmesis was smaller than that of the panel evaluation. However, there are some treatment sequelae, such as disturbing scars and skin changes, that can not be evaluated by BRA measurements. Therefore, the methods of cosmetic evaluation used in a study must be chosen in a way that balances reliability and comprehensiveness.

Cosmetic assessment of breast-conserving surgery for primary breast cancer

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.

Cosmetic outcome of breast-conserving therapy in Chinese patients with early breast cancer

BACKGROUND

Breast-conserving surgery combined with radiotherapy has emerged as an alternative to mastectomy for women with early breast cancer, and cosmetic outcome has correlated closely with the psychosocial and physical well-being of the patient. Cosmetic outcome assessment after breast-conserving therapy in Chinese patients has so far not been conducted among the clinicians, the patients or their spouses.

METHODS

The cosmetic results from breast-conserving therapy were evaluated in a group of 33 patients who had been selected as suitable for undergoing local excision, axillary dissection and postoperative radiation therapy for early stage breast cancer. The success of the procedures was assessed by the patients, the clinicians and the patient's spouse, and their ratings were compared with each other.

RESULTS

Eighty per cent of the patients and their spouse were satisfied with the cosmetic outcome. Using McNemar's test, when the groups were evaluated on a case-by-case basis, there was a good level of concordance between the patients and their spouses, and that of the patients and the clinicians.

CONCLUSIONS

Evaluation of the cosmetic and psychosocial sequelae of breast cancer patients is essential when new approaches to treatment are introduced; our data suggest that cosmetically successful breast conservation is feasible in a selected group of Chinese women with early breast cancer.

Amitriptyline effectively relieves neuropathic pain following treatment of breast cancer

The effectiveness of amitriptyline in relieving neuropathic pain following treatment of breast cancer was studied in 15 patients in a randomised, double-blind placebo-controlled crossover study. The dose was escalated from 25 mg to 100 mg per day in 4 weeks. The placebo and amitriptyline phases were separated by a 2-week wash-out period. Visual analogue and verbal rating scales were used for the assessment of pain intensity and pain relief. Other measures included the number of daily activities disturbed by the pain, the Finnish McGill Pain Questionnaire, adverse effects, anxiety, depression, pressure threshold and grip strength. Amitriptyline significantly relieved neuropathic pain both in the arm and around the breast scar. Eight out of 15 patients had a more than 50% decrease in the pain intensity ('good responders') with a median dose of 50 mg of amitriptyline. The 7 patients who had a less than 50% effect had drug concentrations equaling those of the good responders. The 'poor responders' reported significantly more adverse effects with amitriptyline and placebo than the good responders. It is concluded that amitriptyline effectively reduced neuropathic pain following treatment of breast cancer. However, the adverse effects of amitriptyline put most of the patients off from using the drug regularly.

Pain and other symptoms after different treatment modalities of breast cancer

PURPOSE

The aim of this study was to analyse the risk factors that predispose women to chronic symptoms related to the treatment of breast cancer.

PATIENTS AND METHODS

A questionnaire was sent to 569 women who had undergone modified radical mastectomies with axillary evacuation (MRM) or breast resection with axillary evacuation (BCT).

RESULTS

Pain, paraesthesias and strange sensations were reported by half of the patients. The chronic pain slightly affected the daily lives of about 50% of the patients and moderately or more the daily lives of about 25% of the patients. Pain was reported significantly more often after BCT than after MRM both in the breast scar (BS) and in the ipsilateral arm (IA). The patients with chronic pain were significantly younger and had larger primary tumours. Postoperative complications increased the incidence of chronic pain in the IA. The highest incidence of pain in the IA was reported by patients who had had both radio- and chemotherapy. The fact that the incidence of pain (IA) had a significant correlation with the incidence of paraesthesias, oedema, strange sensations and muscle weakness may be an indication of nerve injury.

CONCLUSIONS

Chronic pain was more common after breast-conserving surgery than after radical surgery. Surgical complications and postoperative radiotherapy and chemotherapy increased the risk of chronic pain and other symptoms. Modifications in the treatment protocol and preclusion of postoperative complications may be necessary in order to minimize chronic treatment-related symptoms.

Factors influencing cosmetic results after conservation therapy for breast cancer

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.

Cosmetic and functional outcomes of breast conserving treatment for early stage breast cancer. 1. Comparison of patients' ratings, observers' ratings, and objective assessments

The cosmetic and functional results of breast conserving therapy were evaluated in a sample of 76 patients with early stage breast cancer, treated by wide local excision, axillary dissection and postoperative radiotherapy between 1975 and 1985. A comparison was made between patients' ratings, independent ratings by two observers (an oncology nurse and a radiation oncologist) and objective measurements. In approximately 40% of the cases, moderate to large differences in the appearance of the treated versus the untreated breast were reported by patients and clinical observers alike. When evaluated on an individual level, the observers' ratings showed relatively high inter-rater agreement (kappa = 0.64), but low levels of concordance were found between the patients' and observers' ratings (kappa < 0.10). Approximately half of the patients reported limited arm or shoulder function, generally mild in nature. Compared to the patients', the observers' ratings of arm edema were significantly lower, indicating 20% mild and 5% more severe swelling. Objective measures of cosmesis and function correlated moderately with the observers' and patients' ratings. Both cosmetic and functional results were found to be significantly related to time elapsed since treatment, with patients treated longer ago exhibiting more problems. The cosmetic and functional outcomes were not related to the patients' age. The results suggest that the patients' opinion can provide important additional information in the evaluation of cosmetic and functional results of breast conserving treatment.

Cosmetic and functional outcomes of breast conserving treatment for early stage breast cancer. 2. Relationship with psychosocial functioning

The relationship between cosmetic and functional results of breast conserving therapy and psychosocial functioning was examined in a sample of 76 patients with early stage breast cancer, who received treatment between 1975 and 1985. The patients were interviewed at their homes regarding breast cosmesis, arm functioning and psychosocial health, and subsequently attended the hospital for independent assessment of cosmetic and functional outcomes by clinical observers. High levels of psychological distress, disturbance of body image, and decreased sexual functioning were noted in approximately one-quarter of the study sample. About half of the patients expressed heightened concern with disease recurrence and their future health. Psychosocial problems were only modestly associated with treatment-related cosmetic and functional outcomes, as determined by clinical ratings and objective assessments. The patients' own ratings of breast cosmesis and arm functioning exhibited somewhat higher correlations with self-reported psychosocial functioning. In particular, a significant association was noted between the patients' ratings of overall cosmesis and arm edema and their body image (r = 0.48 and r = 0.43, respectively). The association between cosmetic and functional results and self-reported psychosocial health was strongest among those patients younger in age and treated longer ago. These findings suggest that, in order to evaluate the impact of breast conserving therapy on the patients' quality of life, the patients' own assessments of cosmetic and functional outcomes should be used as a primary source of information.

Techniques of lumpectomy and axillary dissection

Preservation of the breast with a good or excellent cosmetic appearance is achievable in most patients. Careful attention to the details of surgical technique allows these procedures to be carried out easily and comfortably for the patient and the surgeon alike.

Results of breast conserving treatment of breast cancer

Between 1978 and 1985, 247 patients with primary breast cancer have been treated with breast conserving surgery and external beam radiotherapy. Median follow-up is 3 years and 9 months. Actuarial 5-year disease-free survival for the whole group is 72%; 16 patients (6.8%) have relapsed in the breast to date. Of these, 6 (38%) have died from breast cancer. Patients who have experienced a local recurrence have significantly worse survival than those who remain locally recurrence-free (p less than 0.001). Complication data are presented and shown to be almost entirely mild to moderate and in the range 1-19%. This series shows the breast conserving approach to be effective and at least equivalent to breast ablative procedures in early follow-up.

Breast appearance and function after breast conserving surgery and radiotherapy

Between 1978 and 1985, 247 breast cancer patients were treated with breast conserving surgery and radiotherapy. One hundred and twenty of these patients form the basis of this report, having replied to an 11-point structured questionnaire evaluating breast appearance and breast, shoulder and arm function. Good to perfect cosmetic, functional and overall scores are shown to be in the range 61-89%. The extent of primary surgery and axillary irradiation are the major factors affecting the cosmetic appearance. Other problems with cosmetic and functional assessment from subjective and objective view points are also discussed.

The patients perception of her breast following radiation and limited surgery

Seventy-four patients followed from 1 to 8 years post completion of breast-conserving surgery and radiation for early-stage breast cancer were asked to answer a questionnaire exploring their perception and awareness of the treated breast. The questionnaire was divided into several sections, including "Daily Activities", Pre-menstrual Changes", "Sexual Activities", and a summary "Satisfaction Index" section; when appropriate, comparisons were sought between the treated and untreated breasts. Preliminary results from this study indicate that 70% of all patients are aware of their treated breast in some way during everyday activities. The "Satisfaction Index" of this patient group is very high, with 75% rating their cosmetic result, and 81% their functional result "8" or higher on a scale of "0" to "10","10" indicating "best" or "normal".

Standardization of the surgical technique in breast-conserving treatment of mammary cancer

A number of designations--for example excision, wide excision, lumpectomy, tylectomy, extended tylectomy, partial mastectomy, tumorectomy, segmental resection and quadrantectomy--have been applied to operative procedures aimed at treating mammary carcinoma with preservation of the breast. None of them, however, has been explicitly linked to a defined surgical technique and there is no consensus about the terminology. We propose a simple classification system for breast-conserving procedures, which can facilitate the communication between surgeons and the interpretation and exchange of scientific data. We also describe a strictly defined and locally radical partial mastectomy--a sector resection--which has been used at several centres in Sweden for more than 5 years with a favourable outcome so far in terms of local tumour control and the cosmetic result.

The patient's appraisal of the cosmetic result of segmental mastectomy in benign and malignant breast disease

Women's appraisal of the cosmetic result and their psychosocial adjustment after a standardized segmental mastectomy for benign or malignant breast disease was analyzed on the basis of a mailed questionnaire, which was satisfactorily answered by 263 (92%) of 285 women operated on consecutively. The overall result was favorable: 96.5% of the patients found the new appearance of their breast very good (30.7%), good (44.0%), or acceptable (21.8%). Women with a benign diagnosis ran a two-fold higher risk of being discontented with the new appearance of the breast than those with breast cancer. Complications of radiation therapy, preoperative concern that the breasts are important for the appearance, and anxiousness about the cosmetic result were associated with a significantly elevated risk of being less satisfied with the outcome. The main finding that it is possible to perform a locally radical operation that is highly acceptable to the woman is relevant to the surgical management of potentially malignant mammographic lesions and also to the scientific strategies for future evaluation of breast-conserving treatment modes in malignant disease.
