Skip lesions in the axilla in breast cancer, and their association with micrometastases.

The term 'skip lesion', referring to a tumour-bearing node in the axilla in breast cancer, presupposes that nodal colonization usually occurs in sequence with the path of the lymph flow. Skip lesions are thus out of step with the system. The present study of axillary nodes from 73 node-positive patients demonstrates that skip lesions have much in common with lone micrometastases found at any level, and are thus but a variant of the pattern found in early colonization of the axilla. This in turn indicates that in contrast to a progressive build up of tumour growth first at the lower and later at the middle level, early colonization may be a random process. This again stresses the importance of nodal dissection versus biopsy in the management of breast cancer, particularly in view of recent reports on the prognostic significance of micrometastases.

Modern electronic and chemical thermometers used in the axilla are inaccurate.

UNLABELLED: Rectal and axillary temperatures were measured simultaneously in 83 children using three different thermometer devices providing 166 pairs of results. In the first series consisting of 22 febrile children (44 measurements) and 20 afebrile children (40 measurements), the rectal mercury measurement was compared to an axillary mercury and axillary Tempa-DOT thermometer. The axillary mercury had sensitivity of 14/22 (64%) and specificity of 20/20 (100%) while the Tempa-DOT had sensitivity of 15/22 (68%) and specificity of 19/20 (95%). In the second series comprising 21 febrile children (42 measurements) and 20 afebrile children (40 measurements) the axillary mercury had sensitivity of 11/21 (52%) and specificity of 20/20 (100%) while the electronic thermometer had sensitivity of 10/21 (48%) and specificity of 20/20 (100%). Regardless of the thermometer used, the axilla is a poor alternative to rectal measurements in the diagnosis of fever. CONCLUSION: Mercury-free thermometers, when used in the axilla are as poor alternatives to rectal measurements as mercury-in-glass thermometers.

Phyllodes tumor arising in ectopic breast tissue of the axilla.

We examined a 31-year-old woman with a solid mass in her left axilla. Physical examination and ultrasonography confirmed a 2 cm well-defined mass. Fine needle aspiration biopsy suggested fibroadenoma of breast. Excisional biopsy revealed benign phyllodes tumor of the ectopic breast tissue. Phyllodes tumor in ectopic breast tissue is an extremely rare occurrence. Only nine cases have been reported, including tumors of the vulva, inguinal region and axilla. This is the second case in the axillary region.

[Dissection or irradiation of the axilla in postmenopausal patients with breast cancer? Long-term results and long-term effects in 655 patients].

BACKGROUND: Until 1993 postmenopausal women with breast cancer did not receive adjuvant chemotherapy in our institution even if axillary nodes were involved. So in these patients axillary dissection had no diagnostic value for further treatment. Therefore we started a prospective study in which dissection of axillary nodes was replaced by irradiation in postmenopausal cN0 patients. PATIENTS AND METHODS: From 1986 to 1993 we irradiated 655 patients with breast cancer after breast conserving surgery (BET). In all 144 cN1- and all 209 premenopausal cN0-patients axillary dissection was recommended. Of 302 postmenopausal cN0 patients 129 had breast surgery in our institution. In a total of 129 patients axillary dissection was replaced by irradiation (AxRT-group). They were compared with all 173 patients referred from other hospitals for irradiation after both breast conserving surgery and axillary dissection (AxOP-group). Dissected patients with gross tumor involvement of the axilla or less than eight nodes removed had additional axillary irradiation. Patients age, tumor size, vessel-, muscle- or skin invasion and grading were similar in both groups (Table 1). However, in the AxRT-group there were more patients with negative hormone receptors, multifocal and medial sited tumors. Late complications after dissection and/or irradiation of the axilla were evaluated in 502 patients free of locoregional relapse and with a minimal follow up of 3 years (median 9.5 years). RESULTS: After 5, 10 and 15 years tumor free survival rates were 90%, 82% and 79% in the AxOP-group vs 91%, 82% and 80% in the AxRT-group, respectively (p = 0.95) (Figure 1). Overall survival (p = 0.98) (Figure 2), local (p = 0.47) and axillary control (p = 0.12) were equal in both groups (Figures 3 and 4). However, serious problems like lymphedema of the arm, pain, mobility impairment occurred in 26% patients following axillary dissection but only in 1% after axillary irradiation. No difference in late sequelae after axillary dissection with or without irradiation could be detected (26 vs 27%) (Table 2). CONCLUSION: In postmenopausal cN0-patients axillary dissection should be replaced by axillary irradiation, since it offers the same chance for cure with much lower morbidity.

[Analgesia of the axilla using a paravertebral catheter in the lamina technique].

A 62-year-old female suffered from therapy-resistant pain in the axilla after lymphadenectomy. The pain ranged from 8-10 on the numeric rating scale (NRS) despite multimodal pain therapy (non-steroid anti-rheumatics, opioids, physiotherapy, acupuncture). A paravertebral trial injection was performed preoperatively on the laminae of the thoracic vertebrae Th 2-Th 4. As the patient responded well, a paravertebral catheter was inserted close to Th 4 directly before the revision operation took place the following day. The case study describes the possibilities of eliminating pain segmentally in the axilla and an alternative technique to a paravertebral block (lamina technique).

Management of the axilla in conservatively treated breast cancer: 592 patients treated at Institut Gustave-Roussy.

Between June 1970 and April 1982, 592 patients with unilateral T1 and small T2 breast cancers were managed conservatively at the Institut Gustave-Roussy. The treatment policy for the axilla was to perform a lower axillary dissection and to proceed to axillary clearance ( +/- radiotherapy) in patients with axillary invasion by tumor (N+). Some N+ patients had only lower axillary dissection and radiotherapy. Five hundred fifty-eight patients underwent axillary surgery which was a lower axillary dissection in 374 patients (67%) and axillary clearance in 184 patients (33%). There was axillary invasion in 198 cases (36%). Only five patients relapsed in the axilla and the probability of axillary relapse at 5 years was 1.2%. There were no axillary relapses in N+ patients who had had an axillary clearance whether irradiated or not. The incidence of upper limb complications was significantly greater in patients undergoing axillary surgery and radiotherapy compared with axillary surgery alone (p less than 0.0001). It is concluded that a lower axillary dissection accurately identifies N-patients and an axillary clearance in N+ patients ensures good local control and avoids the morbidity associated with axillary irradiation.

Microscopic extracapsular extension in the axilla: is this an indication for axillary radiotherapy?

PURPOSE: Although the axilla is often treated with radiotherapy (RT) postoperatively when microscopic extracapsular extension (ECE) of lymph nodal metastases is present, little data are available to assess axillary failure in the absence of such treatment. As it has been the practice at this institution to withhold axillary irradiation in the presence of microscopic extracapsular spread, we retrospectively analyzed our results for axillary recurrence, disease-free survival (DFS), and overall survival (OS). METHODS AND MATERIALS: Clinical records were reviewed of 82 women with Stage II node positive breast cancer treated with lumpectomy, axillary dissection, and RT in addition to systemic chemo/hormonal therapy. Axillary surgery consisted of a level I, II, +/- III dissection, with a median of 16.5 nodes removed. Tangential radiotherapy fields were used to treat the breast. All patients were also treated with an abbreviated supraclavicular field with the lateral border medial to the humeral head. Pathological sections were available for review in 72 of the 82 women. RESULTS: Twenty-seven of 72 (37.5%) had evidence of ECE; 45 of 72 (62.5%) had metastatic carcinoma confined within the nodal capsule. Clinical characteristics were comparable between the patients with and without ECE with the exception of (a) pathologic subtype, with a greater percentage of infiltrating ductal tumors associated with ECE (p = 0.044), and (b) number of positive lymph nodes, with 93% of patients without ECE having one to three positive nodes vs. only 56% among patients with ECE (p < 0.001). With a median follow-up of 40 months, 1 of 27 patients (4%) with ECE experienced an axillary failure as a component of first failure compared to 0 of 45 patients without ECE (p = 0.4). There were no isolated axillary failures. Five-year disease-free survival (72% without ECE vs. 57% with ECE, p = 0.12) and overall survival (83% vs. 53%, respectively, p = 0.068) suggested a less favorable outcome for patients with ECE. CONCLUSIONS: Microscopic ECE appears to be associated with increased axillary involvement and decreased survival rather than subsequent axillary failure. Our data suggest that radiotherapy to a dissected axilla may be omitted for the sole indication of microscopic extracapsular disease.

Management of the axilla in women with breast cancer.

There remain several outstanding questions relating to management of the axilla in women with early stage breast cancer. This paper summarises the outcome of a national debate aimed at discussing certain key issues including a) whether axillary dissection has any survival advantage b) is an axillary staging procedure always necessary c) what is the optimum method of staging the axilla and d) whether an axillary dissection is always necessary in cases of a positive sentinel node. Electronic voting was undertaken at the beginning and end of the debate and results are compared and presented herein.

A survey of surgical management of the axilla in UK breast cancer patients.

The aim of our study was to survey management of the axilla by specialist breast surgeons in the United Kingdom (UK). The questionnaire was returned by 371 surgeons, 366 (99%) were consultants and 96% treated more than 50 cases of breast cancer every year. 28% treated patients with invasive breast cancer by axillary clearance (AxCl) alone, 5% used sampling alone (AxNS), 40% used both AxCl and AxNS, 10% AxCl and sentinel lymph node (SLN) biopsy and 17% AxCl, AxNS and SLN biopsy. 9% cleared to level I, and sometimes to level II, 42% to level II and 49% to level III. 56% tried to preserve one or multiple intercostal nerves and 44% routinely divided the intercostalbrachial nerves. 52% performed SNB within trials alone and 36% out side of trials only. A range of techniques were described for the SLN biopsy procedure. There is no consistent practice of managing the axilla in the UK and standardisation is required. SLN biopsy is performed both within and outside of trials and a variety of techniques are used.

Is the clinically positive axilla in breast cancer really a contraindication to sentinel lymph node biopsy?

BACKGROUND: Clinically positive axillary nodes are widely considered a contraindication to sentinel lymph node (SLN) biopsy in breast cancer, yet no data support this mandate. In fact, data from the era of axillary lymph node dissection (ALND) suggest that clinical examination of the axilla is falsely positive in as many as 30% of cases. Here we report the results of SLN biopsy in a selected group of breast cancer patients with palpable axillary nodes classified as either moderately or highly suspicious for metastasis. STUDY DESIGN: Among 2,027 consecutive SLN biopsy procedures performed by two experienced surgeons, clinically suspicious axillary nodes were identified in 106, and categorized as group 1 (asymmetric enlargement of the ipsilateral axillary nodes moderately suspicious for metastasis, n = 62) and group 2 (clinically positive axillary nodes highly suspicious for metastasis, n = 44). RESULTS: Clinical examination of the axilla was inaccurate in 41% of patients (43 of 106) overall, and was falsely positive in 53% of patients (33 of 62) with moderately suspicious nodes and 23% of patients (10 of 44) with highly suspicious nodes. False-positive results were less frequent with larger tumor size (p = 0.002) and higher histologic grade (p = 0.002), but were not associated with age, body mass index, or a previous surgical biopsy. CONCLUSIONS: Clinical axillary examination in breast cancer is subject to false-positive results, and is by itself insufficient justification for axillary lymph node dissection. If other means of preoperative assessment such as palpation- or image-guided fine needle aspiration are negative or indeterminate, then SLN biopsy deserves wider consideration as an alternative to routine axillary lymph node dissection in the clinically node-positive setting.

Is radiation alone adequate treatment to the axilla for patients with limited axillary surgery? Implications for treatment after a positive sentinel node biopsy.

PURPOSE: To estimate the possible efficacy of axillary radiation therapy (AXRT) following a positive sentinel node biopsy (SNB), we evaluated the risk of regional nodal failure (RNF) for patients with clinical Stage I or II, clinically node-negative invasive breast cancer treated with either no dissection or a limited dissection (LD) defined as removal of 5 nodes or less followed by AXRT. MATERIALS AND METHODS: From 1978 to 1987, 292 patients underwent AXRT in the absence of axillary dissection; 126 underwent AXRT following LD. The median dose to the axilla was 46 Gy. The median dose to the supraclavicular fossa was 45 Gy. Among patients found to have positive nodes on LD, adjuvant chemotherapy and tamoxifen were administered to 81% and 7% of subjects, respectively. All patients had potential 8-year follow-up. RESULTS: Six of the 418 patients (1. 4%) developed RNF as a first site of failure within 8 years. Among these 6 patients (1.4%) with RNF as the first site of failure, 4 had simultaneous distant and regional recurrences; and 2 had isolated axillary failures. Three of the 292 patients (1%) with no axillary dissection, none of 84 patients with pathologically negative nodes and 3 of 42 patients (7%) with pathologically involved nodes had RNF as a first site of failure. Radiation pneumonitis developed in 5 patients (1.2%), brachial plexopathy in 5 (1.2%) and arm edema in 4 (1.2%). In all cases, radiation pneumonitis and brachial plexopathy were transient. CONCLUSION: These results imply that AXRT may be an effective and safe alternative to completion dissection for treatment of the axilla following a positive SNB. Further studies comparing these two options in specific patient subgroups are needed.

The role of diagnostic CT scanning of the brachial plexus and axilla in the follow-up of patients with breast cancer.

In order to assess the value of computed tomographic scanning of the axilla and brachial plexus in the management of patients with arm symptoms following treatment for breast cancer, the case notes and diagnostic films of 102 such patients who underwent scanning between 1985 and 1990 at this institution were analysed retrospectively. The clinical indications for requesting computed tomography (CT) of the brachial plexus and axilla included arm oedema (52 patients, 51%), brachial plexus neuropathy (73 patients, 72%), and/or the presence of a palpable axillary mass (18 patients, 18%). Of 102 CT scans, 80 showed either no abnormality (31 patients, 30%), or axillary fibrosis (49 patients, 48%), and 22 (21%) showed radiological evidence of recurrent tumour. Only 4 of 84 patients with no palpable mass had computed tomographic evidence of occult recurrent tumour; all of these had concurrent evidence of distant metastatic disease (lung, liver, bone). Patients have been followed up for from between 1 and 15 years from diagnosis (median 5.5 years). The extremely low yield of tumour recurrence on computed tomographic scanning in the absence of a palpable axillary mass (4/84 patients, 5%; 95% CI 1-12), cannot justify CT as a method of screening for clinically occult axillary relapse in patients with arm symptoms following axillary surgery and radiotherapy for breast cancer. Computed tomographic scanning in these patients should only be employed to confirm the clinical suspicion of tumour as a baseline prior to further treatment.

Does radical surgery to the axilla give a survival advantage in more severe breast cancer?

There is some evidence that more radical treatment of the axilla may improve survival in node-positive disease, but there are concerns about the resultant morbidity from axillary surgery and radiotherapy. The aim of this study was to compare the outcome of axillary node clearance with axillary sampling in similar patients by comparing loco-regional recurrence and overall survival. Patients with invasive breast cancer undergoing axillary surgery between 1986 and 1997 were included. The axillary procedure performed in these patients was either an axillary sample or a level III axillary clearance. To compare like with, the patients were separated into good, moderate and poor prognostic groups by the Nottingham Prognostic Index (NPI) and overall survival was compared by a Kaplan-Meier life table analysis and the log rank test. 734 consecutive patients with operable invasive breast cancer were treated by axillary clearance n=350 or sampling n=384. The mean follow-up in the clearance group was 65 months versus 66 months in the sampled group. Local recurrence in the clearance group was 11% versus 6% in the sampled group, regional recurrence 2% versus 3% and distant metastasis 28% versus 13%. Kaplan-Meier analysis of the three prognostic groups for the clearance versus sampled groups showed no differences in the absolute survival (log rank: P=0.3, P=0.8 and P=0.6 for the good, moderate and poor prognostic groups, respectively). A conservative surgical approach to the axilla did not significantly increase the incidence of local or regional recurrence and the expected survival benefit from a radical axillary clearance was not apparent.

Axilla surgery severely affects quality of life: results of a 5-year prospective study in breast cancer patients.

No long-term prospective study has investigated arm morbidity and patient quality of life. It is unclear to what extent breast cancer patients suffer from arm problems, how long such problems affect their lives, and whether quality of life improves as arm problems abate. This prospective cohort study aims to provide data on the clinical factors associated with arm dysfunction, to estimate its prevalence and to relate arm morbidity to quality of life. The Munich Cancer Registry records clinical details of all cancer patients in and around Munich. Quality of life information was provided directly by breast cancer patients (n = 990) over 5 years. Arm morbidity, including movement limitations, swelling and lymph drainage, and quality of life (EORTC QLQ-C30) were assessed. Up to 5 years after diagnosis, 38% of patients were still experiencing arm problems (swelling and limited movement). Consistently over the 5 years, quality of life was significantly (p < 0.001) lower for patients with arm difficulties. For those whose arm problems dissipated, quality of life significantly improved (p < 0.01). A logistic regression analysis showed that extent of axilla surgery (p < 0.003), comorbidity (CVD and diabetes) (p < 0.003), employment (p < 0.01), younger age (p < 0.02), and operating clinic (p < 0.05) significantly contributed to arm problems. Axilla surgery should be re-evaluated since arm morbidity has such a profound effect on patient quality of life.

[Surgical axilla dissection. Technical standard or obsolete method?].

Axillary lymph node status remains the single most important prognostic parameter and has crucial therapeutic implications in patients with breast carcinoma. Surgical dissection of the axilla is commonly regarded as the standard procedure of axillary staging, its sensitivity and specificity being 99% and 100%, respectively. Apart from giving reliable information on the individual prognosis axillary dissection also contributes to efficient local tumor control in the axilla, as it reduces the risk of local recurrence to less than 1.4% if more than 10 lymph nodes are removed. Alternative, less or non-invasive axillary staging methods have either not yet been sufficiently standardized (immunoscintigraphy, PET-scan, prediction of axillary lymph node status by means of individual risk factors) or are associated with a considerable risk of false-negative staging (up to 50% of patients with positive axillary lymph nodes are not detected by palpation alone, ultrasonography or CT-scan). The basic principles of axillary sampling and axilloscopic dissection are questionable because the number of lymph nodes removed during these procedures is commonly less than 10. With its sensitivity/specificity being comparable to that of standard axillary dissection sentinel lymph node biopsy represents a highly promising approach which will in the future potentially lead to significant optimization of the clinical management of patients with breast cancer, especially those diagnosed in early stages (T1 a, T1 b and T1 c).

[Sonographic anatomy of the axilla].

The axilla represents a region of special interest for small-part sonography. It is easy to demonstrate musculocutaneous, osseous, neurovascular and lymphatic structures. Especially in the presence of breast malignomas with lymphatic drainage to the axillary region sonography of the axillary lymphatic tracts and nodes is essential. The examination is performed with a linear 7.5 MHz transducer with the patient in supine position and the arm hyperabducted. The transducer is directed in transversal and sagittal planes and along the axillary vessels. It is of importance to know exactly the complex topographic anatomy of the axilla. The very dominant pectoral muscles serve as guiding structures. In their vicinity one can find some important groups of lymph nodes. The last station of axillary lymph nodes is the apical group situated along the axillary neurovascular bundle. With their typical echo, the head of the humerus and the coracoid-process facilitate the orientation. Ultrasound is now generally available and should always be used as a secondary method of examination, it breast malignomas are present or suspected in mammogramms, since it supplies important clinical information.

Ultrasound-guided large needle core biopsy of the axilla.

PURPOSE: To study the diagnostic yield and safety aspects of large needle core biopsy of pathologic lesions in the axillary region using a semi-automatic biopsy gun. MATERIAL AND METHODS: A series of 21 consecutive large needle core (14G, 2.1 mm) biopsies of the axilla was evaluated. The biopsies were performed under ultrasound guidance with one (n = 13) or two (n = 8) needle passes. The results were correlated to the clinical, mammographic, ultrasound and surgical histopathologic findings. RESULTS: In 18 patients, specimens large enough for diagnosis were retrieved. In two patients the specimens were insufficient and non-diagnostic. In one patient with a non-malignant yield the result was false-negative. No neural or vascular injury occurred. CONCLUSION: The procedure might be safely employed in the diagnosis of ultrasonographically demonstrable lesions of the axilla, whenever specimens larger than those obtainable with a fine needle are desired.

MR and CT anatomy of the axilla.

PURPOSE: To depict the complex anatomy of the axilla with CT and MR imaging. MATERIAL AND METHODS: The axillary regions of 2 cadavers (with arms hyperabducted) were examined by means of CT and MR. In this position the cadavers were frozen and cryosectioned. The anatomical sections documented by the MR and CT images were compared and anatomical structures were designated. To show the reproducibility of the anatomical structures and to find variations, 20 volunteers were also examined by MR, and 20 consecutive patients without axillary symptoms were examined by CT. RESULTS: The complexity of the axilla was excellently shown by both CT and MR, but MR was able to demonstrate more detail in the small vessels and in the brachial plexus. The comparability of the examinations of the different individuals was best in the axial plane. Some differences appeared in the coronal and sagittal planes caused by different positions of the arm. CONCLUSION: Axillary anatomy was demonstrated in detail and was reproducible with CT and MR imaging.
