111Indium-bleomycin breast and axilla imaging.

111Indium-Bleomycin (111In-Blm), a new radiopharmaceutical, was administered intravenously to 37 patients with benign and malignant breast lesions. Early and delayed images of both the breasts and axillae were made, and results were correlated with physical examination, histopathology of the excised lesion, mammography, and thermography. In 18 patients with malignant disease, clinical examination of the breast and axilla correlated with histopathology in 78 and 54% of the cases, respectively. Images of the breast were accurate (true positives) in 83% of the cases. Images of the axilla were accurate in 62% of the cases. Mammography was correct and suggested malignancy in 88%, and thermography in 73% of the cases. In 19 patients with benign breast lesions, clinical examination of the breast and axilla correlated with histopathology in 68 and 95% of the cases, respectively. Scans of the breast and axilla were correct (true negative) 79 and 95% of the time, respectively. Mammography was correct, and suggested benignancy, in 53% and thermography in 25% of the cases. Imaging of the breasts using 111In-Blm appears to be as accurate as physical examination and mammography for palpable benign and malignant breast tumors. It is less accurate than mammography for microscopic malignancies. Axillary imaging does not appear to be worthwhile because many axillary metastases are too small for detection with current nuclear medicine instrumentation.

Radiotherapy and the management of the axilla in early breast cancer.

The role of radiotherapy in the management of the axilla in early breast cancer is examined. A few, carefully selected, clinically node-negative postmenopausal women may require no intervention to the axilla. Otherwise, surgical clearance is the preferred sole management of the axilla, resulting in an excellent level of local control and providing optimal information for the use of systemic adjuvant therapy. Axillary radiotherapy can also provide equivalent levels of long-term control in the clinically node-negative axilla, but the chronic disabling syndrome of brachial plexopathy is documented at all radiation doses that can sterilize microscopic disease, irrespective of the radiotherapy technique. A combination of radiotherapy and axillary surgery results in an increased morbidity rate compared with either alone. Women who receive radiotherapy to the breast alone are not at risk of brachial plexopathy.

A broad diversity of volatile carboxylic acids, released by a bacterial aminoacylase from axilla secretions, as candidate molecules for the determination of human-body odor type.

Human body odor is to a large part determined by secretions of glands in the axillary regions. Two key odoriferous principles, 3-methylhex-2-enoic acid (3MH2; 4/5) and 3-hydroxy-3-methylhexanoic acid (HMHA; 6) have been shown to be released from glutamine conjugates secreted in the axilla by a specific N(alpha)-acyl-glutamine aminoacylase (N-AGA) obtained from axilla isolates of Corynebacteria sp. However, the low number of different odorants reported in humans stands in contrast to the observed high inter-individual variability in body odors. Axilla secretions of individual donors were, therefore, analyzed in detail. The secretions were treated with N-AGA, analyzed by GC/MS, and compared to undigested controls. Over 28 different carboxylic acids were released by this enzyme from odorless axilla secretions (Table 1). Many of these body odorants have not been reported before from a natural source, and they include several aliphatic 3-hydroxy acids with 4-Me branches, 3,4-unsaturated, 4-Et-branched aliphatic acids, and a variety of degradation products of amino acids. The odor threshold of some of the acids was found to be in the range of 1 ng. Most of these compounds were present in all donors tested, but in highly variable relative amounts, and they are, thus, candidate molecules as key components of a 'compound odor' determining the individual types of human body odor.

Axilla to elbow radial nerve conduction.

Numerous techniques that evaluate radial nerve conduction from the axilla or supraclavicular fossa to the elbow have been reported. A shortcoming of most protocols is determining the precise radial nerve length as it proceeds along the spiral groove. The present study dissected out and measured directly eight cadaver radial nerves from the axilla to the elbow. These values were compared with a new surface tape measurement technique from axilla to elbow across the bicep muscle, obstetrical calipers over this region, and a surface determination approximating the course of the radial nerve posteriorly in the spiral groove. The anterior surface tape-measuring procedure compared most favorably with the actual anatomic length. Nerve conduction velocities were then calculated in 20 volunteers using all 3 techniques and compared with the median nerve in the arm. The anterior and posterior tape measurements yielded a conduction velocity of 72.5 +/- 4.7 and 86.6 +/- 7.0 m/s, respectively, whereas the caliper resulted in 65.7 +/- 3.9 m/s. We conclude that proximal radial nerve length assessment employing an anterior tape measurement from axilla to elbow across the bicep musculature is precise and compares favorably with the actual anatomic length of the radial nerve.

A possible role for ultrasound of the axilla in staging primary breast cancer.

The axillae of 30 patients with primary breast cancer (Stage I and II) were prospectively examined in this pilot study using ultrasound. No patient had palpable axillary lymph nodes on clinical examination. Treatment had involved wide local excision, but no prior form of surgical dissection had been performed on the axilla. Using the contralateral axilla as an internal control, lymph nodes were observed in the ipsilateral axilla alone on ultrasound in 8/30 patients (27%). Following radical irradiation of the breast and local lymph drainage areas, 2/8 patients of the group with observed lymph nodes have relapsed, one with systemic disease and the other with local recurrence in the breast, after a minimum follow-up of 12 months. No patient without observed nodes has recurred. This difference does not reach statistical significance. This technique merits further investigation as an adjunct to current staging procedures for early breast cancer.

Treatment of the axilla in early breast cancer: past, present and future.

BACKGROUND: The optimal treatment of the axilla in early breast cancer is controversial. The present study reviews the pattern and predictors of regional recurrence (RR) and prognosis after RR in patients with early breast cancer treated by conservative surgery and radiotherapy (CS + RT). Implications of the results on current practice and future directions are explored. METHODS: Between 1979 and 1994, 1158 patients with stage I or II breast cancer were treated with CS + RT at Westmead Hospital. Two groups of patients were compared: 782 patients who underwent axillary dissection (axillary surgery group) and 229 patients who received radiotherapy (axillary RT group) as the only axillary treatment. At least 10 lymph nodes were dissected in 82% of the axillary surgery group. Of the women in the RT group, 90% received RT to the axilla and supraclavicular fossa (SCF) only and 10% also received RT to the internal mammary chain (IMC). RESULTS: With a median follow-up period of 79 months for the axillary surgery group and 111 months for the axillary RT group, 27 patients developed a RR (2.8% and 2.2%, respectively). Seven patients (0.9%) in the axillary surgery group and three patients (1.3%) in the axillary RT group developed a RR in the axilla (P, not significant). Of the patients with SCF recurrences, 14 (1.8%) were in the axillary surgery group and one (0.4%) in the axillary RT group (P, not significant). One patient in the axillary surgery group developed concurrent axillary and SCF recurrences, while a patient in the axillary RT group developed an IMC recurrence. Twenty (74%) of the 27 patients with a RR developed a concurrent or subsequent distant relapse (30% and 44%, respectively). In the pathologically node-positive patients, the axillary recurrence rate was higher in those who had less than five nodes removed (17%) than those who had 10 or more nodes removed (0%; P = 0.01). The SCF recurrence rate was higher in patients with four or more positive axillary nodes (9.5%) than in those with 0-3 positive nodes (1.5%; P = 0.003). CONCLUSION: Adequate treatment of the axilla by surgery or RT alone is associated with a low rate of RR. The incidence of distant relapse was substantial in patients who developed a RR, which gives emphasis to the importance of optimizing local-regional control.

Five-node biopsy of the axilla: an alternative to axillary dissection of levels I-II in operable breast cancer.

BACKGROUND: Axillary clearance of patients with early breast cancer is accompanied by a high risk of arm morbidity. Less invasive ways to establish the axillary nodal status are therefore of interest, especially in women with low risk of nodal metastases. METHODS: Four hundred and fifteen breast cancer patients (clinical stage T(0-3) N(0-1) M(0)) were operated in the axilla with a five-node biopsy followed in the same operation by a further dissection of levels I-II of the axilla in order to evaluate the accuracy of the five-node node biopsy compared with level I-II dissection. RESULTS: In all patients the sensitivity of the five-node biopsy was 97.3% with a negative predictive value of 98.5% and a negative likelihood ratio of 0.027. Among cases detected by screening (n=204) and those clinically detected (n=197) the sensitivity of the five-node biopsy was 95.8% and 97.9% respectively, with negative predictive values of 98.7% and 98.0% and negative likelihood ratios of 0.042 and 0.021 respectively. CONCLUSION: Five-node biopsy of the axilla has good accuracy for correctly staging the axilla in both clinically and screening-detected cases. Five-node biopsy is an alternative to axillary clearance and sentinel node biopsy in patients with operable breast cancer.

A case of apocrine adenocarcinoma associated with hamartomatous apocrine gland hyperplasia of both axillae.

We report an apocrine adenocarcinoma of the left axilla associated with hamartomatous apocrine gland hyperplasia of both axillae. The patient, a 69-year-old man, presented with no symptoms or complaints other than an oval mass felt in the left axilla. The mass was resected and histopathological examination revealed a papillary apocrine adenocarcinoma located within hyperplastic apocrine glands. Because gallium scintigraphy performed after the operation still showed bilateral abnormal uptakes, skin and subcutaneous tissues of the bilateral axillary areas were resected. Histological examination demonstrated marked multilobular hyperplasia of the apocrine glands. These hyperplastic glands did not show distinct atypia, and there was no evidence of tumor remnants in the left axilla. The patient has shown no signs of local recurrence or metastasis at 20 months' follow-up. To our knowledge, this is the first case of malignant transformation of hamartomatous apocrine gland hyperplasia (apocrine gland organic hamartoma or apocrine nevus).

Staging of the axilla in breast cancer: accurate in vivo assessment using positron emission tomography with 2-(fluorine-18)-fluoro-2-deoxy-D-glucose.

OBJECTIVE: To evaluate the ability of positron emission tomography (PET) with 18F-fluoro-2-deoxy-D-glucose (18F-FDG) to determine noninvasively axillary lymph node status in patients with breast cancer. BACKGROUND: The presence of axillary lymph node metastasis is the most important prognostic factor in women with breast cancer. It signifies the presence of occult metastatic disease and indicates the need for adjuvant therapy. The only reliable way in which this important prognostic information may be obtained is by performing axillary dissection, which may be associated with significant complications and delay in discharge from the hospital. PET with 18F-FDG can visualize primary cancers in the breast and metastatic tumor deposits. METHODS: Fifty patients with untreated breast cancer had clinical examination of their axilla performed (graded as positive or negative), followed by PET of the axilla and midthorax. PET data were analyzed blindly and graded as positive or negative, depending on the presence or absence of axillary nodal metastases. Cytopathologic assessment of the axillary nodes was carried out within 1 week of PET, by fine-needle aspiration cytology in 5 patients and axillary dissection in 45; the excised specimens were examined by a single pathologist. RESULTS: The overall sensitivity of PET in 50 patients was 90% and the specificity was 97%. Clinical examination of the same patients had an overall sensitivity of 57% and a specificity of 90%. In the 24 patients with locally advanced breast cancer (T3, T4, TxN2), PET had a sensitivity of 93% and a specificity of 100%. In T1 tumors (seven patients), the sensitivity and specificity were 100%. PET had a high predictive value (>90%) and accuracy (94%) in staging the axilla. CONCLUSIONS: PET is a sensitive and specific method of staging the axilla in patients with breast cancer. It may obviate the need for axillary surgery in women with small primary tumors, define the women likely to benefit from axillary dissection, or allow radiotherapy to be substituted for surgery, particularly in post-menopausal women.

Adenocarcinoma with signet ring cells of the axilla: two case reports and review of the literature.

Adenocarcinoma with signet ring cells (ASRC) is a rare skin neoplasm whose histology shows a solid tumor intermingled with signet ring cells in variable numbers. There have been only ten reported cases. All were elderly males affected on the eyelids except for a single case in the axilla. Two new patients with ASRC of the axilla are described. In both of them, immunohistochemical studies revealed neoplastic cells that had differentiated toward apocrine glands. These are the second and third reported cases of ASRC in the axilla, one of them is the first ASRC case in a female. It seemed that the apocrine sweat gland or aberrant breast tissue in the axilla were possible origins of these tumors.

Apocrine adenocarcinoma of the bilateral axillae.

A case of apocrine adenocarcinoma arising in the bilateral axillae is reported. The patient was an 88-year-old Japanese male who complained of a mass lesion and pus-like discharge in the right axilla. Another mass was also noticed in the left axilla. No other neoplastic lesion was found in other sites of the body. The histologic appearances of the bilateral axillary tumors were almost identical. Both were adenocarcinoma with varying degrees of differentiation, composed of glands and nests of atypical epithelial cells with abundant eosinophilic cytoplasm. Some neoplastic cells exhibited cytoplasmic projections on their apical surface. Foci of in situ carcinoma were observed within the neoplastic tissue in the bilateral axillae. The neoplastic cells were immunohistochemically positive for epithelial membrane antigen (EMA) and gross cystic disease fluid protein (GCDFP-15), but negative for carcinoembryonic antigen (CEA). On the basis of their histologic and immunohistochemical features and distinctive location, the tumors were diagnosed as apocrine adenocarcinoma.

Temperature measured at the axilla compared with rectum in children and young people: systematic review.

OBJECTIVE: To evaluate the agreement between temperature measured at the axilla and rectum in children and young people. DESIGN: A systematic review of studies comparing temperature measured at the axilla (test site) with temperature measured at the rectum (reference site) using the same type of measuring device at both sites in each patient. Devices were mercury or electronic thermometers or indwelling thermocouple probes. STUDIES REVIEWED: 40 studies including 5528 children and young people from birth to 18 years. DATA EXTRACTION: Difference in temperature readings at the axilla and rectum. RESULTS: 20 studies (n=3201 (58%) participants) had sufficient data to be included in a meta-analysis. There was significant residual heterogeneity in both mean differences and sample standard deviations within the groups using different devices and within age groups. The pooled (random effects) mean temperature difference (rectal minus axillary temperature) for mercury thermometers was 0.25 degrees C (95% limits of agreement -0.15 degrees C to 0.65 degrees C) and for electronic thermometers was 0. 85 degrees C (-0.19 degrees C to 1.90 degrees C). The pooled (random effects) mean temperature difference (rectal minus axillary temperature) for neonates was 0.17 degrees C (-0.15 degrees C to 0. 50 degrees C) and for older children and young people was 0.92 degrees C (-0.15 degrees C to 1.98 degrees C). CONCLUSIONS: The difference between temperature readings at the axilla and rectum using either mercury or electronic thermometers showed wide variation across studies. This has implications for clinical situations where temperature needs to be measured with precision.

Morphology and development of an apoeccrine sweat gland in human axillae.

Evidence is presented that in adult human axillae there exists a third type of sweat gland tentatively designated as the apoeccrine sweat gland. This type of gland shows a segmental or diffuse apocrinelike dilatation of its secretory tubule but has a long and thin duct which does not open into a hair follicle. The electron microscopy of its dilated segment is often indistinguishable from that of the classical apocrine gland. The less remarkably dilated segment of the apoeccrine gland tends to retain intercellular canaliculi and/or dark cells. These apoeccrine glands are consistently present in adult human axillae regardless of sex or race. In the axillae of the two 6-yr-old subjects, both classical apocrine and eccrine glands were present but no apoeccrine glands were found. Between 8-14 yr of age, the number of large eccrine glands with or without partial segmental dilatation gradually increased. At 16-18 yr of age, the number of apoeccrine glands increased to as high as 45% of the total axillary glands. The data support the notion that apoeccrine glands develop during puberty in the axillae from eccrine or eccrinelike sweat glands.

Transpectoral anterior approach to the axilla for lymph node dissection in association with mastectomy preserving both pectoral muscles and their neurovascular bundles.

In Patey's mastectomy, which is still the most common operation for breast cancer, axillary node dissection (AND) is performed through the base of the axilla after retracting the pectoralis major muscle and excising the pectoralis minor muscle (some surgeons preserve the latter). This has the disadvantage of inadequate exposure of the axilla and the risk of damage to the neurovascular bundles supplying the pectoral muscles, which in the long run may lead to atrophy of these muscles. A transpectoral anterior approach to the axilla for AND in association with mastectomy was attempted in 115 cases to obviate the above-mentioned disadvantages. The approach included: 1) splitting of the pectoralis major between the clavicular and sternal fibers; 2) mobilization and swinging of the pectoralis minor into different directions by means of a sling to facilitate AND at selected levels. The major advantages of this approach were: 1) total preservation of both pectoral muscles with their neurovascular bundles maintained the normal anatomy and function of the shoulder; 2) the axilla was directly approached through the anterior wall instead of through the base; in this way the axillary contents were exposed almost at surface level; 3) the dissection plane could be limited to anterior to and below the axillary vein and the risk of postoperative lymphedema could thus be minimized; 4) change of position of the ipsilateral arm was not necessary; 5) the duration of surgery was reduced. Monoblock ablation of significant and suspected tissues, maintaining the normal anatomy and function of the shoulder, could be easily accomplished with this approach.

MRI appearances of the axilla in treated breast cancer.

Differentiation between recurrent axillary disease and changes due to radiotherapy or surgery has major implications for management in patients following breast cancer treatment, but clinical examination of the axilla may be difficult. This study was undertaken to correlate the MRI appearances of the axilla following breast cancer treatment with clinical outcome. 74 women with treated breast cancer were evaluated by MRI (0.5 T) and the appearances defined by consensus. Outcome was assessed by long-term clinical follow-up. 62 women had symptoms related to the axilla while 12 were scanned to stage the axilla. None of the axillary staging group had abnormal MRI appearances and none of these subsequently developed recurrence. The 62 symptomatic women were subdivided according to MRI appearances. 22 had normal axillary appearances, 18 had an axillary mass and 22 women had abnormal axillary appearances (rated mild, moderate and severe) in the absence of a mass. Normal axillary appearances on MRI excluded recurrent disease as the cause of symptoms with a specificity of 94.7% and a positive predictive value (PPV) of 95.5%. The presence of an axillary mass was commonly but not exclusively due to recurrent disease (sensitivity 68.4%, specificity 88.4%, PPV 72.2%). Sensitivity for diagnosis of axillary recurrence was increased to 89.5% with a specificity of 76.7% if the criteria for recurrent disease were taken as either the presence of an axillary mass or severe axillary changes in the absence of a mass lesion.

Malignant fibrous histiocytoma (MFH) in axilla.

Palpable axilla mass in woman is relatively rare. Almost all palpable lumps in axilla are axillarys accessory breasts without mass lesion. All diseases develop in breast can also develop in axillarys accessory breasts and other soft tissue mass can occur in axilla. Malignant fibrous histiocytoma (MFH) is the most common malignant soft tissue tumor, but axillarys MFH is extremely rare. We report our experience with a 75-year-old woman with MFH in axilla, treated with wide excision.

[The muscular arch of the axilla and its nerve supply in Japanese adults].

We examined 94 axillary regions of 47 Japanese adults and found the muscular arch of the axilla (Maa) in five sides of three cadavers as well as the tendinous arch of the axilla (Taa) in two sides of two cadavers. The results are summarized as follows: 1) The frequency of Maa was 6.4% of the total bodies and 5.3% of the sides in this series. 2) In the left side of a 57-year-old male (No. 427), Maa was attached to the surface of the coracobrachialis muscle after fusing with the dorsal surface of the inserting tendon of the pectoralis quartus muscle. Both muscles were supplied by the caudal pectoral nerve (Npc) from the medial pectoral nerve. Moreover, in this same specimen, the sternalis muscle was recognized on the ventral surface of the pectoralis major muscle. In the left side of a 93-year-old female (No. 386), the cranial part of the muscular arch of the axilla (Cpa) was extended to the coracoid process by a tendon and attached to the abdominal part of the pectoralis major by two muscle bundles supplied by independent branches from Npc. One muscle bundle was attached to the lower margin of the abdominal part of the pectoralis major on the same plane, and the other bundle was located on the dorsal surface of the abdominal part. In a 74-year-old female (No. 411), the well-developed lateral part of the muscular arch of the axilla (Lpa) was attached to the inferior side of the tendinous arch. According to Ruge (1914) and Kasai et al. (1977), this arch was in the transition of the muscle bundle of Cpa to the arch. In the right side of the same specimen, only the thoracodorsal nerve (Ntd) was distributed into Lpa, whereas in the left side, only Npc supplied branches to Lpa. 3) The axillary arch was classified into 8 types based on the form and the supplying nerve of Cpa and Lpa. Cpa consisting of the muscle bundle is Type I, and Cpa consisting of the tendinous arch is Type II. We proposed that only Type II-A, with Cpa as tendinous arch and no Lpa, be designated as Taa (found in two cases), and the others as Maa. The following types were found in this study: Type I-A, consisting of only Cpa supplied by Npc (two cases); Type I-D, consisting of Cpa supplied by Npc and Lpa supplied by Ntd (one case); Type II-B, consisting of the tendinous arch and Lpa supplied by Npc (one case); Type II-D, consisting of the tendinous arch and Lpa supplied by Ntd (one case). 4) From the above findings, it can be suggested that Maa of varying shapes have been formed by a portion of the latissimus dorsi muscle supplied by Ntd, together with the pectoralis subcutaneous muscle, consisting of the pectoralis abdominalis, humeroabdominalis, humerodorsalis and ventrolateralis muscles supplied by Npc. The latter three muscles were proposed by Ura (1937) as the panniculus carnosus muscle, which was well developed in some lower mammalian orders. However, early investigators suggested that Maa was derived from the panniculus. Maa might have occurred as a rudimentary phylogenetic remainder in an early human embryonic stage.

The axilla: to clear or not to clear? That is the question!

The prime objectives for axillary dissection are staging and treatment to cure. No physical examination, no imaging techniques, and no tumor markers can replace axillary dissection for staging. Further, axillary node status in potentially curable breast carcinomas is still considered the single best predictor of outcome and the primary determinant of the use of systemic therapy. Finally, locoregional tumor control seems to improve survival, emphasizing meticulous axillary dissection. Today, the question to be asked is not whether or not to clear the axilla; rather, the question should go: How do we distinguish node-negative patients from those who are node-positive without clearing the axilla unnecessarily? No surgeon would advocate dissecting the axilla in node-negative patients if nodal status could be ascertained by a different technique. Ongoing trials addressing the reliability of the sentinel node technique seem promising, and this technique may perhaps in the near future solve the problem of distinguishing node-negative patients from those with axillary spread. For the time being, the necessity of determining axillary status and to treat for cure can hardly be questioned. Therefore, once axillary spread has been demonstrated in one way or another, an adequate and meticulous axillary dissection should be performed.
