This is called lymphedemaand it can become a life-long problem. If the lump you feel isn't sore, or barely sore; and it lingers for several weeks, then it's wise to see a doctor, in order to eliminate the possibility of breast cancer. A cancer with lower TNM numbers is usually easier to treat and has a better outlook Breast carcinoma lymph nodes prominent parenchyma survival. Determining whether the lymph nodes are free of cancer or not is an essential part of the breast cancer staging process and will help determine treatment and prognosis. The cellular microenvironment and metastases. When you go in for a mastectomy, the surgeon will remove all of the lymph nodes on that side near your affected breast. Another surgical option called a sentinel node biopsy is Pantyhose and pumps being used on select breast cancer patients to determine whether breast cancer is present in the lymph nodes. Why do they swell up?

Lymph nodes are small clumps of immune cells that act as filters for the lymphatic system.

  • What do underarm lymph nodes do?
  • Our bodies have a network of lymph vessels and lymph nodes.
  • When you have breast cancer in your lymph nodes, the cancer has spread beyond the breast tissue.

Language: English Portuguese. Axillary staging of patients with early-stage breast cancer is essential in the treatment planning.

Currently such staging is intraoperatively performed, but there is a tendency to seek a preoperative and less invasive technique to detect lymph node metastasis. Ultrasonography is widely utilized for this purpose, many times in association with fine-needle aspiration biopsy or core needle biopsy. However, the sonographic criteria for determining malignancy in axillary lymph nodes do not present significant predictive values, producing discrepant results in studies evaluating the sensitivity and specificity of this method.

The present study was aimed at reviewing the literature approaching the utilization of ultrasonography in the axillary staging as well as the main morphological features of metastatic lymph nodes. The presence or absence of metastatic disease in the regional lymph node chain is crucial information for the definition of staging, treatment and prognosis of breast cancer.

Axillary lymphadenectomy in association with histological analysis is still the gold standard in the evaluation of such lymph nodes; but this method is associated with relevant morbidity. With the advances in breast imaging diagnosis and consequential increased incidence of cases of early stage disease, the presence of axillary lymph nodes metastasis has declined, and a less aggressive option became necessary.

In the metaanalysis by Kell et al. Such data raised the question of what is the actual benefit of wide lymph node dissection in cases where the sentinel lymph node is compromised. Such benefit is particularly unknown in the cases of micrometastasis and isolated tumor cells in which clinical meaning is still undetermined. The studies on the subject are still controversial, and currently most services adopt the wide axillary approach, even in those cases where the sentinel lymph node is minimally compromised 5.

The identification of new prognostic markers, the better understanding of tumors behavior and the technological developments in imaging methods have a great potential of bringing changes in axillary staging in the future, by selecting patients eligible to less aggressive interventions. Both clinical examination and mammography demonstrably do not present appropriate accuracy in the identification of axillary lymph nodes metastasis 7 and several studies approach other imaging techniques, such as: ultrasonography alone or in association with Doppler flowmetry; fine needle aspiration biopsy FNAB or core biopsy; computed tomography; positron emission tomography; magnetic resonance imaging; elastography.

Currently, no imaging method has enough negative predictive value to avoid a surgical approach to the axilla in cases where no lymph node involvement is identified 8 , however an increasing number of studies include such methods as part of the therapeutic planning.

A study is currently being undertaken at the European Oncology Institute, comparing SLNB versus observation alone when axillary ultrasonography is negative in patients with small breast cancer candidates to breast conserving surgery 9. Axillary ultrasonography plays a relevant role in the staging and follow-up of regional lymph nodes.

It is an easily accessible noninvasive method which is helpful in obtaining material for cytology and histology. The present study was aimed at discussing the utilization of ultrasonography in axillary staging, with emphasis on the main morphological changes of metastatic lymph nodes observed at such method. The adopted method was the systematic bibliographical research for the production of a review article to meet the proposed objective. The search was carried out in the period of January through August of In the present article, 22 references which best covered the proposed theme were utilized.

Ultrasonography is widely available and, as combined with FNAP or core biopsy, it is the most significant method for preoperative evaluation of axillary lymph nodes In the presence of a negative cytological or histological result for axillary metastasis, the negative predictive value of SLNB is increased; on the other hand, in the presence of a positive result, the surgical time is shortened by not performing biopsy.

Another benefit from such method would be the reduction in the occurrence of inappropriate lymphatic mapping by previously identifying, by means of ultrasonography, lymph nodes with tumor cell deposits increasing the lymphatic pressure, thus reducing the radioactive colloid uptake A previously mentioned, a positive sentinel lymph node, in many cases, is the only affected lymph node, and biopsy would not be an appropriate method to evaluate the axillary involvement extent in such a case 2 , 6.

On the other hand, the utilization of ultrasonography in association with FNAP, in the study developed by Moore et al. In spite of presenting a high accuracy in many studies, the diagnostic criteria for malignancy and the indication of the method remain controversial 4. Usually, a benign lymph node is ovoid, with a hypoechogenic cortex, extremely thin or even invisible at ultrasonography with a hyperechogenic hilum due to connective tissue trabeculae, lymphatic tissue cords and medullary sinusoids.

Changes such as cortical thickening, hilum decrease or absence, changes in shape or vascular pattern, are considered suspicious. Currently many studies utilize cortical thickening and hilum absence as criteria for definition of the risk for metastasis 11 , 12 - Absence of the hilum, making the lymph node completely hypoechogenic, is the most specific alteration for metastatic disease 13 , 16 , but such finding is present only in cases of advanced disease.

The great challenge in sonographic diagnosis lies in the evaluation of lymph nodes whose cortex and hilum are observed in varied forms, corresponding to early stages of metastatic disease, with such cases being responsible for the largest proportion of false-negtive cases 11 - 13 , Metastatic cells in the lymph reach the lymph nodes through afferent lymphatic vessels on the convex aspect of the organ.

Then, the lymph is filtered through the cortex, paracortex and finally the hilum Metastatic deposits accumulate in the lymph node peripheral area, causing enlargement of the cortex, usually focal at early stages , or uniform. Minimum lymph node involvement, with deposits between 0. With the objective of estimating the suspicion based on image, many authors have developed classifications based on the cortical thickness.

Cho et al. Bedi et al. Lymph nodes classified as types 5 and 6 were considered suspicious, with indication for biopsy; reactional changes were frequently observed in type 3; while type 4 was considered as probably benign, since such type comprised most falsenegative results Figures 1 to 7.

Mainiero et al On the other hand, Deurloo et al. One observes that value for cortical thickness utilized as a cut-off point for metastatic disease varies a lot in the literature, as well as sensitivity and specificity of the method as a function of the selected value.

Representation of a cortex with a normal thickness. Measure of the fatty hilum greater than the cortex thickness. Cortical thickening representation. Lymph node with cortical thickening at ultrasonography. As regards other morphological changes, the change in the lymph node shape generally occurs in advanced cases, in association with hilum absence. Size used to be considered a relevant criterion, but recent studies have not demonstrated a significant relationship between size and malignancy 13 , Moore et al.

The vascularization studied at Doppler ultrasonography, basically follows two patterns, namely the central pattern, with a single hilum vascular signal or dispersed signals distributed at the center of the organ, and the peripheral pattern, where a linear signal is observed along the peripheral zone of the organ.

Peripheral vascularization is more frequently found in metastatic lymph nodes, while the central pattern is more frequently found in the absence of malignancy. The indices of resistance, pulsatility and peak systolic velocity do not differentiate between malignant and benign axillary lymph nodes, but the relevance of such data has already been demonstrated in studies on cervical lymph nodes The importance of the utilization of Doppler as a diagnostic criteria is observed as it is associated with other morphological characteristics and not as an isolated criteria 15 , The indiscriminate utilization of ultrasonography followed by FNAP or core biopsy has demonstrated to be hardly practical and expensive 12 , The largest the primary breast tumor is, the highest is the chance of axillary metastasis, so the indication for the procedure is clear in these cases.

Mainiero et al. Once an abnormal lymph node is found, one faces the question on which procedure would be more appropriate: FNAP or core biopsy. Such a decision should be made taking into account various peculiar aspects of each method. FNAP is fast, with high sensitivity and specificity, besides being less invasive; on the other hand, it requires an experienced cytologist, a professional who is only available at a small number of institutions.

Core biopsy, albeit more expensive, provides material for histological and immunohistochemical analysis and has a higher sensitivity as compared with FNAP However, a negative result by means of such a method does not exclude SLNB, as the core biopsy, as well as FNAB, presents a percentage of false-negatives as a function of small metastatic deposits It is important to highlight that although core biopsy presents a higher potential for complications such as bleeding and nerve injury, it has demonstrated to be very safe with a technique described by Abe et al.

Ultrasonography represents an important resource in the preoperative evaluation of axillary lymph nodes in patients with breast cancer. The utilization of this method allows for the identification of the axillary disease extent and assists in percutaneous biopsy, but it presents a limited benefit in those cases with minimum lymph node involvement, such as in those cases of micrometastasis and isolated tumor cells. Changes such as cortical thickening and hilum absence are predictors of metastatic disease, and cytological or histological analysis is indicated in cases where such changes are present.

The choice between FNAP and core biopsy should be made according to the equipment and professionals available at the institution. Axillary lymph nodes in breast cancer patients: sonographic evaluation. Radiol Bras. National Center for Biotechnology Information , U.

Our bodies have a network of lymph vessels and lymph nodes. The other two are the size of breast cancer tumor and whether it has spread to other areas of the body. This lump will usually be soft and moveable, and feel sore or painful. This is a surgical technique that injects a radioactive blue dye into the site of the breast cancer tumor. In these types of tumors, estrogen can make the cancer grow faster. But one or two might settle in a new area, begin to grow, and form new tumors. From there, the breast cancer can metastasize spread systematically to other areas of the body such as the bone, liver, lung, or brain.

Breast carcinoma lymph nodes prominent parenchyma. What is Node-Positive Breast Cancer?

The human circulatory system includes the cardiovascular and lymphatic systems, two networks that play complementary roles. As you may recall from a high school biology class, the cardiovascular system consists of arteries and veins. Arteries transfer blood, enriched with oxygen and fuel, to cells.

Veins return blood, carrying carbon dioxide, back to the lungs. The lymphatic system moves lymph between tissue and the bloodstream via lymph ducts, lymph nodes, lymph vessels and organs. It also includes adenoids, the spleen, the thymus and tonsils. If the lymph nodes detect an unrecognizable substance they will create an antibody, which flows in blood circulation to target and destroy the foreign material in cells throughout the body.

Swollen lymph nodes are a sign they are making infection-fighting white blood cells to combat a recognized threat to the body. The threat can range from something relatively trivial, such as a cold or throat infection, to something far more serious, such as cancer. Understanding the health of the lymphatic system can play a crucial role in the diagnosis, prognosis and treatment of cancer tumors. It is often difficult to feel normal axillary lymph nodes.

Not all enlarged axillary lymph nodes feel the same. It is also important to mention that enlarged axillary lymph nodes are not necessarily a sign of cancer. However, we strongly advise you to consult with a medical provider if you are concerned about enlarged axillary lymph nodes.

Enlarged axillary lymph nodes may stem from a range of causes. If a patient does not have cancer, some of the local, non-cancerous causes of enlarged axillary lymph nodes include:. Enlarged axillary lymph nodes can be a symptom of the following local or metastasized systematic cancer maladies:. The doctor will let you know how many lymph nodes were taken out and how many of those had cancer cells in them. For instance, if 5 lymph nodes were taken out and 3 had cancer cells they will let you know.

You will also be told the severity of the cancer in each node: minimal, significant, or extra-capsular cancer has grown outside the lymph node walls. This is known as "localized breast cancer. This will give you more chance for a cure and higher survival rate. If breast cancer is "regionally advanced" and found in the lymph nodes, the above treatments will be done along with added treatments to stall cancer growth in the lymph nodes and any cancer cells that have spread.

These additional treatments may include:. If your breast tumor is "hormone receptor positive" or receptive to estrogen, an estrogen blocking medication will be given. In these types of tumors, estrogen can make the cancer grow faster.

Your doctor may also choose to do a hysterectomy and remove the ovaries to prevent further estrogen production in the body. Using these estrogen blocking medications can either stop or slow the growth of breast cancer tumors.

Your doctor may also advise you to not use any estrogen containing or estrogen like substances. These types of breast cancer treatment target the cancer cells wherever they have gone in the body. They can block certain things the cells need to grow and reproduce. Targeted therapies work in a few different ways:. If breast cancer cells are found in distant lymph nodes, they may choose to do another round of radiation targeting those lymph nodes to prevent the cancer from spreading into the surrounding organs near those lymph nodes.

While this isn't always effective in preventing Stage IV breast cancer, it may be helpful. Stage III breast cancer in the lymph nodes has a fairly positive prognosis. Many women who are diagnosed at this stage are successfully treated and experience remission.

Here is how breast cancer in lymph nodes occurs: We have lymph nodes all over our body that are connected via the lymphatic system. How Is It Diagnosed? Breast cancer that has not invaded the lymph nodes will usually be treated with: Surgery Radiation Chemotherapy This is known as "localized breast cancer.

These additional treatments may include: 1. Endocrine Therapy If your breast tumor is "hormone receptor positive" or receptive to estrogen, an estrogen blocking medication will be given.

Some of these entities have distinctive imaging appearances knowledge of which can be helpful in suggesting the correct diagnosis. The axilla is often included on routine imaging studies and detection of masses in this region is not uncommon. To offer a differential diagnosis, radiologists need to be aware of the range of conditions that may occur. Some lesions have distinctive imaging appearances, and this knowledge may be helpful in reaching the correct diagnosis.

Level 1 LN lie inferolateral to the pectoralis minor muscle, Level 2 lie posterior, and Level 3 lie superomedial to the muscle also known as infraclavicular LN. This classification is useful for clinical and radiological staging of the axilla. Breast cancer metastases tend to first involve level 1 LN and then levels 2 and 3 in a stepwise fashion. Reactive changes in LN can be caused by local skin and soft tissue infections as well as systemic infections such as HIV, syphilis, toxoplasmosis, brucellosis, CMV, histoplasmosis and tuberculosis.

Inorganic dusts such as silica and coal can also enlarge LN. Coarse calcification may also be seen. There are no characteristic features to differentiate different causes of infective and reactive lymphadenopathy. However, calcification may be a feature of silicosis, and TB may have characteristic features as described above. The commonest cause of unilateral reactive lymphadenopathy includes infected skin lesion, or mastitis or breast abscess in females.

Metastatic disease represents the most common cause of lymphadenopathy. LN metastases may develop from primary malignancies originating from the breast, lung, head and neck, stomach, ovary or ipsilateral arm.

This is the principle of sentinel LN biopsies for breast cancer. Mammographically, the affected LN appear dense and rounded with irregular or spiculated borders and absent hilar fat. Microcalcifications may occur in breast, thyroid and ovarian cancer Fig. Early sonographic appearance of nodes containing metastases may be nonspecific. These LN are usually hypoechoic and may undergo cystic necrosis with development of an echolucent focus especially in squamous cell carcinoma, or less commonly coagulative necrosis with development of an echogenic focus Fig.

Diffuse enhancement may occur with total replacement of the LN by tumour. Lymphomas are tumours arising in the reticuloendothelial and lymphatic systems and may be localised or disseminated, frequently involving the axilla.

Reticulation producing a micronodular echo pattern is commonly encountered. Perinodal oedema and intranodal calcification are uncommon. Lymphadenopathy can be a feature of connective tissue diseases including rheumatoid arthritis, SLE, systemic sclerosis, psoriasis, scleroderma and dermatomyositis.

In rheumatoid disease, mammography may show intranodal microcalcifications. Ultrasound features include enlargement of the hypoechoic cortical region and an increase in short axis measurement from a mean 0. Focal cortical lobulation or the absence of hilum is not observed with rheumatoid nodes.

On mammography the LN may appear calcified. Ultrasound commonly demonstrates hypoechoic, oval or round LN with distinct margins and a homogenous echotexture. Extrathoracic lymphadenopathy is usually without calcifications. Silicone is transported to regional LN by macrophages and induces a granulomatous reaction. On mammography, LN appear enlarged and radiodense Fig. Amyloidosis represents a heterogeneous group of protein misfolding disorders and is characterised by deposition of fibrils in extracellular tissues.

The two major forms are primary AL and secondary AA amyloidosis. On CT, involved LN may appear calcified with punctate calcifications. A palpable mass may develop with hormonal stimulation during menarche, pregnancy or lactation.

On mammography and ultrasound this appears as an area of normal appearing fibroglandular tissue. On CT, they appear as fluid density masses, and may appear heterogeneous due to the presence of blood and protein. MRI shows a homogeneous high signal intensity mass on T2 weighted sequences and may help to define the anatomy and extent of the lesion.

Haemangiomas are common benign endothelial tumours. Areas of calcification phleboliths may be seen, suggesting the diagnosis and high vascularity may be evident on doppler. A schwannoma is a benign peripheral nerve sheath neoplasm arising from Schwann cells. It is encapsulated and eccentrically located adjacent to the parent nerve. Large schwannomas undergo degenerative changes including cyst formation, haemorrhage, calcification and fibrosis.

Lipomas are common benign tumours composed of adipocytes and present as well circumscribed masses of fat divided into lobules by thin connective tissue septa. Blood vessels or muscle fibres may be prominent. Atypical features suggestive of liposarcoma on MRI include a poorly defined mass, a heterogenous appearance, and presence of variable contrast enhancement on both CT and MRI.

Trauma or surgery can result in localised collections of serous fluid seromas , lymphatic fluid lymphocoeles or blood haematomas. The appearances of a haematoma on sonography evolve with age: anechoic when hyperacute and hypoechoic with low level heterogenous internal echotexture when acute. Clotted blood may form an echogenic debris level. Subacute haematomas can progress to an irregularly marginated cystic mass with thickened hyperechoic walls and internal septations.

Chronic haematomas are usually hypoechoic with thick irregular walls, internal septations and enhanced through transmission, but may appear solid.

When acute, it appears isointense on T1, and variable intensity on T2. Subacute to chronic haematoma are hyper intense on both T1 and T2. Fat necrosis is a benign condition which most commonly occurs as a result of trauma, and may be evident on mammography as a spiculated mass, lipid filled cyst or calcification. Ultrasound demonstrates a solid or complex cystic lesion. The presence of internal echogenic bands is highly specific for fat necrosis.

On MR, the appearance depends on the degree of fat necrosis, fibrosis or inflammatory reaction. Abscess formation in the axilla may occur following local trauma, obstruction of sweat or sebaceous glands, infection of hair follicles or within LN due to bacterial or tuberculosis lymphadenitis.

If features consistent with a benign aetiology are not identified, percutaneous biopsy with fine needle or core biopsy CB is recommended. Given that the sensitivity of these techniques does not appear to be significantly different, this choice should be based on technical factors such as degree of procedural difficulty LN accessibility, depth and proximity of vital structures , the skill of the operator and availability of a skilled cytopathologist.

The suspected underlying pathology may also influence choice of technique. For the diagnosis of TB, cystic lesions, abscesses and seromas, aspiration with a fine needle will usually provide sufficient material. Investigations for lymphoma should include flow cytometry which can identify a malignant clonal lymphoid proliferation. While this can be performed on a FNA, core biopsies provide more material that can be used for ancillary studies which can more definitively classify the type of lymphoma.

The core biopsies should not be fixed in formalin but must be sent immediately to pathology with a request for lymphoma studies. They may be placed on sterile paper from the procedure pack , moistened with sterile saline to prevent drying.

If there is any delay, one or two small cores should be put into refrigerated Roswell Park Memorial Institute RPMI tissue preservative and the remaining cores fixed in formalin. If the mass does not have characteristic features of a lymph node, and particularly if large, further imaging with CT or MRI may assist with identifying the organ of origin and further characterisation.

MRI can help show pathognomonic features of neural tumours, thereby preventing the need for a needle biopsy, which may be associated with intense pain.

In some centres, the results of the Z trial have changed the approach to preoperative needle biopsy of axillary LN in breast cancer patients. The results of Z showed that women with minimal axillary nodal disease who only had sentinel node biopsy SNB did as well as those whose SNB was positive and who had a full axillary dissection.

This has made some centres reluctant to biopsy axillary LN unless there are suspicious findings, as a positive biopsy result in the presence of subtle changes may preclude an otherwise eligible patient from undergoing the post Z treatment algorithm sentinel node biopsy rather than full axillary dissection. The axilla is often visualised with mammography and ultrasound.

This review discusses the range of lesions that may occur, outlining some common pathologies and those with distinctive imaging appearances. Knowledge of these imaging features may help the radiologist to narrow the differential diagnosis. Volume 61 , Issue 5. The full text of this article hosted at iucr.
