Objectives The Clinical Breast Exam Revisited: Review: Whats New? Contribution of CBE to the early detection of breast cancer Cynthia Kreger, MD Variables influencing the effectiveness of the CBE Professor Clinical Internal


  1. Objectives The Clinical Breast Exam Revisited: Review: What’s New? • Contribution of CBE to the early detection of breast cancer Cynthia Kreger, MD • Variables influencing the effectiveness of the CBE Professor Clinical Internal Medicine Division of General Internal Medicine • Best method for performing the CBE The Ohio State University College of Medicine according to consensus statement and current evidence Breast Cancer in Mammography – Benefits Context and Limitations • 2 nd leading cause of cancer death in women • Ability to identify • Patient goes at nonpalpable cancers recommended intervals • Most common cause of death due to cancer • Clear contribution to • Technological in women 45-55 reduction in mortality limitations • False negatives based • Affects one in 8 American women in her on patient lifetime characteristics • Survival inversely related to tumor size • False positives • Delay of diagnosis is the second leading • Missed abnormalities cause of malpractice claims in the US • Clinicians overestimate efficacy of • Many of us have some personal experience mammography 1

  2. What is the Contribution of the What is the Goal of the CBE? CBE to Early Detection? Goal: • Lack of RCT demonstrating CBE • To detect palpable abnormalities in reduces mortality asymptomatic women at an earlier stage of • Population-based study: disease when treatment options are greater and more effective � 71.2% of cancers identified by BSE • To evaluate patient symptoms � 19.6% of cancers identified by mammogram • To provide screening in women for whom � 9.3% of cancers identified by CBE mammography is not recommended • Relied on recall, was in younger • To provide screening in limited resource women settings What is the Contribution of the What Are The Barriers To And Variables Influencing CBE? CBE to Early Detection? Physician Variables • More recent studies suggest that: � 5.1% of malignancies detected by CBE in women • Unconvinced about the value of the exam with negative, benign or probably benign • Discomfort with the exam mammograms • Confidence, skill • This is over 10,000 otherwise undetected cancers per year • Considerable variability in way the exam is taught � 10.7% of cancers identified by CBE alone and performed � CBE plays a role in detection of interval cancers, • Reliance on technology to provide the answer in screening for women under 40, and in women who do not receive high quality mammograms or • Limited time who do not follow recommendations for screening mammography • Experience in detecting abnormal breast lesions 2

  3. What Are The Barriers To And CBE Skills Among Graduating Variables Influencing CBE? Primary Care Physicians • Only 50% examined the patient in a supine position with arm over head Patient characteristics • Only 55% performed systematic palpation � Tissue density, nodularity, menopausal status • Only 37% examined the supraclavicular Tumor characteristics region � Size, depth, mobility, firmness • Only 25% examined the axilla • Some evidence that CBE skills diminish during training The Components of the What’s Different Regarding Inspection? CBE Have Not Changed • Inspection • Inspection � No studies document the independent • Nodal Evaluation benefit of inspection � Taking into account limited time, inspect • Breast Palpation while palpating � Increase inspection if abnormality found on palpation 3

  4. What’s Different What’s Different Regarding Regarding Inspection? Lymphatic Examination? • Inspection • Palpation of lymph nodes should: � Look for subtle changes such as • Include the supra and flattening of breast contour, area of infra clavicular areas fullness, asymmetry, difference in venous pattern, scaliness of skin • Include the apical, central, pectoral, and � Findings such as erythema, retraction or subscapular areas dimpling, or changes in the nipple such as inversion, tend to be late signs • Be performed with the patient seated What’s Different What’s Different Regarding Palpation? Regarding Palpation? • Emphasizes the following core competencies • MammaCare method � Positioning � Most widely studied � Perimeter � Palpation � Recommended by CDC and the ACS � Pressure � Pattern � Time 4

  5. What’s Different Include the Full Perimeter During Palpation Regarding Positioning? The Cahan Position • Perimeter as pentagon Note two characteristics: • Sternum to the lateral chest wall at the • Position of patient’s mid-axillary line ipsilateral arm, the hand resting on forehead, • Clavicle to below the which softens pectoralis muscle infra-mammary ridge • Position of hips/knees to contralateral side, • Junction of the shoulder with the which helps to distribute breast tissue anterior chest, at anterior axillary line centrally over chest wall Performing the Performing the Examination Examination Palpation/Pressure Palpation/Pressure • Three fingers • Pay particular attention to upper outer quadrant, and under nipple • Dime-sized circles • No need to assess for nipple • Overlapping by one finger breath discharge � with fingers sliding over breast tissue • In women with breast implants - perform the CBE in the same way � helps to ensure no areas are missed • In women post mastectomy - palpate � palpate directly over nipple all of chest wall and along incision 5

  6. What’s Different Performing the Examination Regarding Pattern? Time - A Critical Variable • Vertical strip pattern in contrast to concentric • Duration of exam (and consistency of search circles pattern) are the factors most consistently shown to correlate directly with sensitivity and • Palpate from distal to specificity proximal toward you � 1 minute increase in exam duration resulted in 1.8 more lumps being noted, but also increased false • Efficacy in detecting lumps positive rates • Vertical strip (67.9%) vs. spoke pattern (44.7%) � Optimal duration is influenced by a variety of factors: proficiency of examiner, breast size, lumpiness, body • Vertical strip (64.4%) vs. concentric circles weight, tenderness (38.9%) � A thorough exam may take up to 3-4 minutes per side What Can I Take Home? Video Demonstration Don’t overestimate the efficacy of mammography, don’t • underestimate the importance of CBE • Use the preferred method for CBE � Include infra and supraclavicular in lyamphatic At this point I would like to share evaluation a video clip that highlights � Consider the use of Cahan’s position selected portions of the exam. � Three level palpation, vertical strip pattern, cover full perimeter of breast tissue • Remember that time and consistency of search pattern are the most critical variables • Any abnormality found on CBE, even in the face of a normal mammogram, needs evaluation to appropriate resolution 6

  8. Mammogram Paddles Adequate Mammograms Compression • Screening • Lowers x-ray dose • Diagnostic • Reduces thickness • Immobilizes breast • Spreads out tissue 8

  9. ACR Recommendations for Screening Versus Sreening Mammogams Diagnostic Mammogram • Baseline between ages 35-40 • Screening • Annual screening mammograms after � No breast problems age 40 � No self history of breast cancer � Over age 40 Diagnostic Mammogram • Mass • Persistent, pin-point pain • Personal history of breast Ca • Increase in size/firmness • New nipple retraction • Itching/flackiness of nipple • Spontaneous nipple discharge- serous/bloody 9

  10. Duty of Referring Doctor • Results of Clinical Exam • 10% of breast cancers are • Location of Palpable Lesion not seen by mammograms or ultrasounds • Recent Needle Biopsy Bi-Rads Code • Bi-Rads 1- Negative Ultrasound of • Bi-Rads 2- Benign findings • Bi-Rads 3- Short follow up the Breast • Bi-Rads 4- Suggestive of Ca • Bi-Rads 5- Strongly suggestive • Bi-Rads 6- Known Ca 10

  11. Value of Breast US DMIST • Cysts • Margins/blood flow – solid mass • Digital mammographic screening trials • Lymph nodes • Study to determine value of MRI and • Duct evaluation digital mammography • Silicone implant leak • F/U known Ca • Perform aspiration/biopsy 11

  12. Acrin Guidelines for Digital Mammograms Screening MRI • > 20% risk of Breast Ca • Detect 15-28% more Ca in premenopausal women or those • BRCA 1 and BRCA 2 gene mutation over 50 with dense breasts • 1 st degree relative with mutation • Strong family history • Chest radiation between 10-30 MRI in Contralateral Breast • 10% of breast ca patients develop contralateral Ca • DMIST showed a 3% increase in detection in ca patients 12

  13. Image Guided Biopsy • Stereotactic biopsy Stereotactic • Ultrasound guided biopsy Breast Biopsy Stereotactic Table 13

  14. Biopsy Clip Biopsy Needle Not Stereo Candidate • > 300 Pounds Ultrasound • Breast too small • Superficial lesion Guided • Deep lesion • Bleeding problems • Unable to lie prone 14
