A prospective assessment of surgical risk factors in 400 cases of skin-sparing mastectomy and immediate breast reconstruction with implants to establish selection criteria.

BACKGROUND: Although attempts have been made to identify the risk factors leading to complications after combined skin-sparing mastectomy and immediate prosthetic breast reconstruction, hardly any criteria are available to preoperatively distinguish patients in whom such an eventful postoperative course may be expected. Therefore, the authors wanted to establish which factors increase the risk of surgical complications to such a level as to adjust their indications for immediate breast reconstruction after skin-sparing mastectomy. METHODS: The authors prospectively studied the clinical relevance of six patient-related and nine procedure-related characteristics as potential risk factors for a complicated surgical outcome in 400 combined procedures in 309 patients by univariate and multivariate logistic regression analysis. Risk factors that proved significantly correlated with loss of implant by both analyses were accepted as clinical selection criteria that distinguish potential candidates with an unacceptably high risk of such loss. RESULTS: Mild complications occurred significantly more often in patients who were older than the mean age of 43 years and in breasts that were more than average sized or operated on by a fellow in oncologic surgery. Implants were lost significantly more often in patients who were obese or smoked and in breasts that were more than average sized. CONCLUSIONS: The clinically relevant increase of risk of implant loss should lead to reluctance to perform combined skin-sparing mastectomy and immediate prosthetic breast reconstruction in obese patients who smoke (32 percent loss) and in those with more than average sized breasts (27 percent loss).

Sentinel node biopsy and concomitant probe-guided tumor excision of nonpalpable breast cancer.

BACKGROUND: Preliminary data have shown encouraging results of a single intratumoral radiopharmaceutical injection that enables both sentinel node biopsy and probe-guided excision of the primary tumor in patients with nonpalpable breast cancer. The aim of the study was to evaluate this approach in a large group of patients. METHODS: Lymphoscintigraphy was performed in 368 patients with nonpalpable breast cancer after intratumoral injection of (99m)Tc-nanocolloid (.2 mL, 123 MBq, 3.3 mCi) guided by ultrasound or stereotaxis. The sentinel node was pursued with the aid of vital blue dye (1.0 mL, intratumoral) and a gamma ray detection probe. In case of breast-conserving surgery, the probe was used to guide the excision. RESULTS: At least one sentinel node could be identified intraoperatively in 357 patients (97%), of whom 69 had involved nodes (19%). Age over 60 years was associated with less frequent nonaxillary lymphatic drainage and absence of internal mammary chain dissemination. Tumor-free margins were obtained in 262 (89%) of the 293 patients who underwent segmental excision. Re-excision of the primary tumor bed was performed in six patients (2%). During a median follow-up of 22 months, one breast recurrence and one axillary recurrence were observed. CONCLUSIONS: Lymphatic mapping and probe-guided tumor excision of nonpalpable breast cancer by intralesional administration of a single dose of (99m)Tc-nanocolloid and blue dye resulted in 97% identification of the sentinel node and in tumor-free margins in 89% of the patients who underwent breast-conserving surgery. Longer follow-up is needed to substantiate the accuracy and safety of this technique.

Clinical implications of sentinel nodes outside the axilla and internal mammary chain in patients with breast cancer.

PURPOSE: The aim of this study was to determine the incidence, location, surgical identification rate, tumor status, and clinical implications of sentinel nodes outside the axilla and internal mammary chain. PATIENTS AND METHODS: In 785 breast cancer patients, pre-operative lymphoscintigraphy was performed after intratumoral injection of 116 MBq 99mTc-labeled nanocolloid (0.2 ml; 3.1 mCi). Sentinel nodes were pursued using a gamma-ray detection probe and vital blue dye. RESULTS: Lymphoscintigraphy visualized sentinel nodes outside the axilla and internal mammary chain in 91 of the 785 patients (12%). Sentinel nodes (106) were identified in 80 patients. These nodes were found in the following locations: 50 in the breast, 31 in the infraclavicular fossa, 19 between the pectoral muscles, and 6 within the supraclavicular bed. Eighteen nodes contained a metastasis (17%) and were removed from 16 patients. The treatment strategy was adjusted in 12 of them with the addition of adjuvant local or systemic therapy. Two additional patients with an unusually situated tumor-negative sentinel node were spared an axillary node dissection that would otherwise have been performed. CONCLUSION: Unusually situated sentinel nodes were visualized in 12% of the patients. The treatment was adjusted in 18% of patients in whom these nodes were identified.

Additional axillary metastases and stage migration in breast cancer patients with micrometastases or submicrometastases in sentinel lymph nodes.

BACKGROUND: In patients with breast cancer, micrometastases and submicrometastases are increasingly found in sentinel nodes when step sectioning and/or immunohistochemical staining are applied. The aims of the current study were to investigate the incidence of micro- and submicrometastases in the sentinel node, to estimate the risk of additional metastases in the remaining axillary lymph nodes, and to consider implications for staging and treatment. METHODS: A total of 2150 breast cancer patients who had undergone axillary sentinel node biopsy between 1999 and 2004 were retrospectively evaluated. RESULTS: In all, 649 patients (30%) had a tumor-positive axillary sentinel node. Of these 649 patients, 148 had (23%) micrometastases and 105 (16%) submicrometastases. Of the 148 patients with micrometastases, 106 underwent axillary lymph node dissection (ALND) and additional metastases were found in 20 patients (19%). Sixteen (15%) had macrometastases and were upstaged. The other 4 patients had additional micrometastases. Seven of the 106 patients (7%) received additional systemic treatment based on the findings in the axillary lymph nodes. Fifty-four of the 105 patients with submicrometastases underwent ALND. Two (4%) of them had additional macrometastases and were upstaged and 2 had additional micrometastases. None received additional treatment based on the ALND findings. CONCLUSIONS: Of the involved sentinel nodes, 23% contained micrometastases and 16% submicrometastases. Additional macrometastases were found in 15% and 4%, respectively, and treatment was altered in 7%. Based on these findings, offering additional treatment of the axilla is suggested in patients with micrometastases, but refraining from ALND in patients with submicrometastases in their sentinel node.

Breast-conserving treatment with or without radiotherapy in ductal carcinoma-in-situ: ten-year results of European Organisation for Research and Treatment of Cancer randomized phase III trial 10853--a study by the EORTC Breast Cancer Cooperative Group and EORTC Radiotherapy Group.

PURPOSE: The European Organisation for Research and Treatment of Cancer conducted a randomized trial investigating the role of radiotherapy (RT) after local excision (LE) of ductal carcinoma-in-situ (DCIS) of the breast. We analyzed the efficacy of RT with 10 years follow-up on both the overall risk of local recurrence (LR) and related to clinical, histologic, and treatment factors. PATIENTS AND METHODS: After complete LE, women with DCIS were randomly assigned to no further treatment or RT (50 Gy). One thousand ten women with mostly (71%) mammographically detected DCIS were included. The median follow-up was 10.5 years. RESULTS: The 10-year LR-free rate was 74% in the group treated with LE alone compared with 85% in the women treated by LE plus RT (log-rank P < .0001; hazard ratio [HR] = 0.53). The risk of DCIS and invasive LR was reduced by 48% (P = .0011) and 42% (P = .0065) respectively. Both groups had similar low risks of metastases and death. At multivariate analysis, factors significantly associated with an increased LR risk were young age (< or = 40 years; HR = 1.89), symptomatic detection (HR = 1.55), intermediately or poorly differentiated DCIS (as opposed to well-differentiated DCIS; HR = 1.85 and HR = 1.61 respectively), cribriform or solid growth pattern (as opposed to clinging/micropapillary subtypes; HR = 2.39 and HR = 2.25 respectively), doubtful margins (HR = 1.84), and treatment by LE alone (HR = 1.82). The effect of RT was homogeneous across all assessed risk factors. CONCLUSION: With long-term follow-up, RT after LE for DCIS continued to reduce the risk of LR, with a 47% reduction at 10 years. All patient subgroups benefited from RT.

Skin-sparing mastectomy and immediate breast reconstruction by use of implants: an assessment of risk factors for complications and cancer control in 120 patients.

BACKGROUND: Combined skin-sparing mastectomy and immediate reconstruction by use of an implant is increasingly accepted as a therapy for patients with breast cancer or a hereditary risk of breast cancer. Because little and contradictory evidence regarding possible risk factors for postoperative complications is available, the authors retrospectively assessed 13 such factors. They also evaluated the oncological safety of the procedure. METHODS: From July of 1996 through June of 2000, 174 skin-sparing mastectomies were combined with immediate breast reconstruction in 120 patients. The authors assessed the influence of five patient-related and eight breast-related characteristics on the incidence of a complicated postoperative course by univariate and multivariate analyses. Oncological safety was evaluated by observed recurrent disease and 5-year survival. RESULTS: Severe complications were observed in 17 patients of the 120 patients (14 percent), or 19 of the 174 breasts (11 percent). The patient-related characteristics of age and being operated on unilaterally significantly increased the risk of complications. Resident plastic surgeons and previous breast-conserving therapy including radiotherapy significantly increased the risk of implant loss. The local relapse rate among patients operated on for cancer was 0.02. The actuarial 5-year survival rate among patients who underwent curative mastectomies was 0.96. CONCLUSIONS: Combined skin-sparing mastectomy and immediate reconstruction by use of an implant is oncologically safe, but the risk of postoperative complications cannot be neglected. The authors' observations may offer guidance for adapting indication and treatment strategies for patients with breast cancer or increased hereditary risk of such cancer.

Non-axillary breast cancer recurrences after sentinel node biopsy.

BACKGROUND AND OBJECTIVES: The primary lymphatic pathway of patients with breast cancer is toward the axilla, but lymph drainage is also possible towards the internal mammary chain and the supraclavicular fossa. In the current article, the development of breast cancer recurrences at these two sites after sentinel lymph node biopsy is reviewed. METHODS: Since 1997, 803 patients underwent sentinel lymph node biopsy with intratumoral injection of 99mTc-nanocolloid and patent blue dye in The Netherlands Cancer Institute. All sentinel nodes as visualized on the lymphoscintigraphy images were pursued. The patients were followed prospectively for a median period of 34 months. Patients with a lymph node recurrence outside the axilla were identified and their lymphatic mapping procedures were reviewed. RESULTS: Four of the 803 patients (0.5%) developed regional lymph node recurrences outside the axilla. One recurrence was located in the internal mammary chain, the other three in the supraclavicular bed. One or two of these patients also had an axillary recurrence. The sentinel node procedure had failed in two of the four patients. CONCLUSION: The incidence of nodal recurrences outside the axilla is low. Although all extra-axillary sentinel nodes were pursued, some of these recurrences concern missed sentinel nodes that harbor metastasis. Identification of all sentinel nodes and subsequent treatment of the involved basins may reduce the risk of breast cancer recurrences in these unusual locations.

Contrast-enhanced MRI in breast cancer patients eligible for breast-conserving therapy: complementary value for subgroups of patients.

The aim of this study was to identify patients prior to breast-conserving therapy (BCT) who have complementary value of contrast-enhanced magnetic resonance imaging (MRI) over conventional imaging in the assessment of tumor extent. All patients were eligible for BCT according to conventional imaging, and underwent preoperative MRI as part of this study. One hundred and sixty-five patients (166 tumors) were included. MRI was defined to have complementary value if conventional imaging underestimated or overestimated tumor extent (by more than 10 mm compared to histology) and MRI assessed the extent accurately. Logistic regression was employed to identify characteristics that are predictive of the complementary value of preoperative MRI. MRI had complementary value in 39 cases (23%). Patients <58 years old with irregular lesion margins at mammography and discrepancy in tumor extent by more than 10 mm between mammography and ultrasonography had a 3.2x higher chance of accurate assessment at MRI (positive predictive value 50%, negative predictive value 84%, p=0.0002). Preoperative MRI in patients eligible for BCT is more accurate than conventional imaging in the assessment of tumor extent in approximately one out of four patients. Subgroups of patients in whom MRI has complementary value may be defined by the differences in clinical and imaging features.

Increased risk of breast cancer development after diagnosis of salivary gland tumour.

The aim of this study was to evaluate whether patients with salivary gland tumours are at increased risk of developing breast cancer. A retrospective cohort study was performed. Female patients (n = 439) with a salivary gland tumour (major and minor) were included. The diagnosis was confirmed histologically. The median follow-up was 5.4 years. Fifteen patients out of 439 with a salivary gland tumour subsequently developed breast cancer, with a mean time interval of 64 months. On the basis of incidence rates in the general population 5.93 breast cancers would be expected. The standardised incidence ratio (SIR) was 2.5 (95% confidence interval: 1.4-4.2; P = 0.003). Increased SIRs were also observed for other solid malignancies, but the numbers were small (n < 5). It is concluded that female patients with a salivary gland tumour have a 2.5 times increased risk of developing breast cancer. Breast screening of these patients is therefore recommended.

Additional breast lesions in patients eligible for breast-conserving therapy by MRI: impact on preoperative management and potential benefit of computerised analysis.

This study was conducted to assess the incidence and impact of additional findings from magnetic resonance imaging (MRI) on the workup of patients eligible for breast-conserving therapy (BCT) and to optimise the specificity of further workup by combining radiological reading with computerised analysis. One hundred and sixteen patients eligible for BCT underwent preoperative MRI where the gold standard was histology or follow-up (median 35 months, range 23-48). The incidence of additional findings and impact on treatment (wider excision/conversion to mastectomy) were assessed. The specificity of referral to further workup was also assessed without and with computerised analysis. Additional findings from MRI occurred in 41% of patients, requiring workup in 78%. In 22% the findings were malignant, causing change in treatment. Specificity was 33% (10/30) for radiological reading alone, and 97% (29/30) combined with computer analysis. Our findings show that additional findings preoperative MRI required workup in approximately one-third of patients and we suggest that combining radiological reading with computer analysis has the potential to accurately exclude benign lesions from further workup.

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.

Lymphatic drainage patterns from the breast.

OBJECTIVES: The aim of this study was to describe the lymphatic drainage patterns from the 5 "quadrants" of the breast. SUMMARY BACKGROUND DATA: Lymphatic mapping has provided techniques to visualize and harvest sentinel nodes in various locations and has generated renewed interest in nodes outside the axilla. METHODS: Between January 1997 and June 2002, 700 sentinel node procedures were performed in patients with cN0 breast cancer. Preoperative lymphoscintigraphy was performed after injection of 99mTc-nanocolloid into the tumor in a volume of 0.2 mL and a mean dose of 107.7 MBq (2.8 mCi). Intraoperatively, the sentinel node was pursued with the aid of a gamma-ray detection probe and patent blue dye (1.0 mL, into the lesion). The patients were divided into 5 groups according to the location of the primary breast cancer. In each group, a distinction was made between palpable and nonpalpable lesions of the breast. RESULTS: Drainage to either an axillary or an extra-axillary basin was observed in 678 patients. Both palpable and nonpalpable lesions may drain toward the internal mammary chain, although the latter more frequently, regardless of the quadrant. Drainage was also observed to supraclavicular, infraclavicular, interpectoral, and intramammary sentinel nodes. CONCLUSION: In each quadrant, a breast cancer may drain to sentinel nodes in various locations. There is a distinct difference in drainage patterns between palpable and nonpalpable lesions. These findings may improve the assessment of lymphatic dissemination in invasive breast cancer.

A comparison in cosmetic outcome between per-operative interstitial breast implants and delayed interstitial breast implants after external beam radiotherapy.

BACKGROUND AND PURPOSE: Interstitial implants for brachytherapy boost in the breast conserving therapy of breast cancer can be performed in two ways; implants during the tumor excision (per-operative implants) or after the external beam therapy (delayed interstitial implants). Differences in cosmetic outcome were investigated. PATIENTS AND METHODS: Cosmetic results in 47 patients having a per-operative implant were compared to 123 patients having a delayed interstitial implant in a matched case-control study. Cosmesis was scored on a four-point-scale varying from 0 (excellent) to 3 (poor). RESULTS: After mean follow-up of 63 months, three observers found no difference in cosmetic outcome between the two groups after adjustment for variables found to be related with cosmesis (difference in mean score 0.50, P=0.26). Implant volume at 100% isodose was not found to differ (P=0.084) between the per-operative group (mean 102 cm3, S.D. 34 cm3) and the delayed group (mean 93 cm3, S.D. 29 cm3). CONCLUSIONS: Performing per-operative implants has not led to smaller implants. The method of performing brachytherapy does not result in marked differences in cosmetic outcome.

Quality assurance of axillary radiotherapy in the EORTC AMAROS trial 10981/22023: the dummy run.

PURPOSE: To assess and if needed improve the compliance of participating institutions to the radiotherapy guidelines of the EORTC AMAROS trial 10981/22023 comparing axillary radiotherapy to axillary surgery in sentinel node positive patients with early stage breast cancer. MATERIALS AND METHODS: A transverse contour and a frontal view radiograph of the axillary region of a 'dummy' patient were sent to all institutions intending to participate in the trial with the request to produce a radiotherapy treatment plan according to the protocol guidelines. Additional information on dose prescription, the treatment technique and field matching with breast fields and internal mammary lymph node fields was requested in a questionnaire. RESULTS: Eighteen institutions have performed the dummy run. At first assessment, the dose was not specified according to the protocol in seven cases, while two institutions did not comply with the dose prescription of 50 Gy in 25 fractions. Dose heterogeneity was over 20% in 10 institutions, caused by the use of a two-field technique in eight cases. Ten institutions did not apply special techniques to obtain non-overlapping match planes. In 10 cases, one or more field borders or blocks were positioned incorrectly. Following recommendations from the quality assurance committee given to the participating institutions on an individual basis, 10 institutions adapted their technique. Thereafter, 16 institutions could be accepted for trial participation. CONCLUSIONS: A number of potential protocol deviations were found at first assessment. Since recommendations led to a large number of adaptations by the participants, a considerable improvement in protocol compliance and inter-institutional consistency was achieved.

Intratumoral versus intraparenchymal injection technique for lymphoscintigraphy in breast cancer.

A 1.5-cm nonpalpable mass was detected in the upper outer quadrant of the left breast by screening mammography in a 55-year-old woman. The patient was scheduled for a sentinel node procedure, and lymphoscintigraphy was performed the day before surgery. Unintentionally, she received an intraparenchymal tracer injection 3 cm away from the malignant lesion instead of the intended intratumoral injection. Lymphoscintigraphy revealed two sentinel nodes in the axilla. A second dose of Tc-99m nanocolloid was injected the next day into the primary tumor through a catheter that had been inserted under ultrasound guidance the previous day. Once more, a lymphoscintigraphic image was obtained that showed additional sentinel nodes in two different regions outside the axilla. This observation supports the authors' contention that lymphatic watersheds exist in the breast and highlights the importance of tracer administration into or close to the tumor.

Reproducibility of the assessment of tumor extent in the breast using multiple image modalities.

The accuracy of breast-conserving therapy (BCT) is limited by uncertainties in the assessment of tumor extent. These uncertainties may result in too wide treatment volumes leading to undesirable cosmetic results, or too narrow treatment volumes leading to higher probabilities of local recurrence. The aim of this study is to quantify the reproducibility of the assessment of tumor extent in the breast at preoperative diagnostic imaging with multiple imaging modalities and at pathology, applied to (1) determining minimum surgical safety margins to reduce the probability of underestimating the tumor extent due to uncertainty in the radiological assessment, and (2) defining the minimum difference between two measurements of tumor size that indicates a significant reduction of tumor extent in response to neoadjuvant chemotherapy or hormonal therapy. Measurements of the largest tumor diameter in mammography, ultrasonography, contrast-enhanced magnetic resonance imaging, and at pathology were retrieved, retrospectively, for 105 patients eligible for BCT. An analysis of variance technique is employed to separate uncertainty at preoperative diagnostic imaging from uncertainty at pathology. The random variations are thus calculated independently of the systematic deviations, avoiding the necessity to choose a gold standard. Moreover, the technique does not require repeat measurements of tumor extent, thus allowing the use of data that is obtained in daily clinical practice, while avoiding bias due to recollection. The magnitude of the random variations is used to determine minimum surgical safety margins and to define the minimum significant difference between two measurements of tumor size. The overall random variations in the assessment of tumor extent are on the order of 3 mm (1 s.d.) with only little differences of about 0.3 mm between the four techniques. The dependence of the random variations on tumor size was found significant (p < 0.05) for mammography (2.7 mm vs 4.2 mm, 1 s.d.) and ultrasonography (2.5 mm vs 3.8 mm, 1 s.d.) for tumors up to 17 mm compared to those that are larger. A minimum surgical safety margin on the order of 5 mm for tumors up to 17 mm and 7 mm for larger tumors takes the uncertainty in radiological assessment of the tumor extent into account effectively in 95% of the performed surgical procedures. A minimum difference in largest tumor diameter of 7 mm for tumors up to 17 mm and 9 mm for those that are larger indicates a significant (p < 0.05) reduction of tumor extent in response to neoadjuvant chemotherapy or hormonal therapy. The reproducibility of the assessment of tumor extent at preoperative diagnostic imaging is of comparable magnitude to the reproducibility at pathology. The uncertainty in the preoperative assessment of tumor extent constitutes a large portion (5-7 mm) of the current safety margin in breast-conserving surgery (10 mm). In monitoring response to neoadjuvant chemotherapy or hormonal therapy using repeat imaging before and after treatment, the current clinical guidelines may produce approximately 10% false-positive responses for tumors between 20 and 30 mm.

Should the hunt for internal mammary chain sentinel nodes begin? An evaluation of 150 breast cancer patients.

BACKGROUND: The aim of this study was to determine the visualization rate, identification rate, and clinical implications of biopsy of sentinel nodes in the internal mammary chain (IMC) in patients with breast cancer. METHODS: From January 1999 to December 2002, 691 sentinel node procedures were performed. Preoperative lymphoscintigraphy was performed after injection of (99m)Tc-labeled nanocolloid into the tumor (.2 mL; 115 MBq; 3.1 mCi). The sentinel node was surgically identified with the aid of patent blue dye and a gamma ray detection probe. RESULTS: The sentinel node in the IMC could be harvested in 130 (87%) of the 150 patients in whom it was visualized on the images and contained metastases in 22 (17%) of these 130 cases. In nine patients (7%), the IMC sentinel node was tumor positive, whereas the axilla was tumor-free. Stage migration was seen in all patients with a tumor-positive IMC sentinel node (17%). There was a change of management in 38 (29%) of the 130 patients: institution or omission of radiotherapy to the IMC, adjuvant systemic therapy, or omission of an axillary lymph node dissection. CONCLUSIONS: Pursuit of IMC sentinel nodes improves the staging of patients with breast cancer and enables treatment to be better adjusted to the needs of the individual patient.
