Disclosures: • None
Objectives: • Cancer statistics • Upper body morbidity after breast cancer • Define Post-mastectomy Syndrome • Discuss epidemiology and etiology of symptoms • Differential diagnosis for Post-mastectomy Syndrome
U.S. Cancer Statistics • 14.5 million with hx of cancer alive in 2014 • 1,658,370 new cancers expected to be diagnosed in 2015 • 589,430 expected to die of cancer in 2015 • Cancer death accounts for nearly 1 in 4 deaths • Direct medical costs for cancer treatment was $88.7 billion in 2011 Cancer Facts and Figures 2015 www.cancer.org
U.S. Breast Cancer Statistics • 2.5 million breast cancer survivors • 1 in 8 women affected by breast cancer • 234,190 new cases expected to be diagnosed in 2015 • 231,840 women • 2,350 men • 40,730 deaths expected in 2015 • 40,290 women • 440 men Cancer Facts and Figures 2015 www.cancer.org
U.S. Breast Cancer Statistics • Most commonly diagnosed cancer in women (except for skin cancer) • Second most common cause of cancer death in women (after lung cancer) • For all stages combined: • 5 year survival rate 89% • 10 year survival rate 83% • 15 year survival rate 78% Cancer Facts and Figures 2015 www.cancer.org
Breast cancer treatment • Surgery • Lumpectomy or mastectomy • Sentinel lymph node biopsy or axillary lymph node dissection • Radiation • Hormonal therapy • Chemotherapy • ACT (Adriamycin, Cyclophosphamide, Taxol) • CMF (Cyclophosphamide, Methotrexate, Fluorouracil) Morbidity and functional impairments as a consequence of breast cancer treatment is common

Upper body morbidity after breast cancer • Associated with alteration in use and function of the upper body • Has adverse physical, psychosocial and social ramifications which influence daily life and quality of life • 10-64% of women report upper body symptoms between 6 months and 3 years after treatment • Pain reported in 12 to 51% of patients • 20% develop lymphedema Hayes, S.

Upper Extremity Pain in Breast CancerFrequency of Current Self-Reported Symptoms by Year McCredie, et al. The Breast. 2001;10:515-22.
Post-mastectomy syndrome - Definition • Chronic neuropathic pain condition that can occur following surgery to the breast • The exact mechanism is unknown but thought due to nerve damage, particularly those involving dissection of the axilla • Can start anytime after surgery but persists beyond normal healing time (~3months) • Pain neuropathic in character • Pain located in the chest wall, axilla, arm, or shoulder on the affected side
Post-mastectomy syndrome - Continued • Symptoms vary depending on the type of surgery and the adjuvant treatment received as well as the individual patient • The extent of treatment consistently identified as a significant risk factor • Affects as many as 40% of patients
Post-mastectomy Syndrome – Continued (2) • Symptoms include one or more of the following: • Pain (nociceptive and neuropathic, phantom, CRPS) • Sensory changes (paresthesias, dysesthesias, allodynia) • Spasms • Muscle atrophy • Muscle weakness • Capsular contracture • Limited range of motion • Edema/lymphedema – axilla, chest wall, breast, arm • Cording
Pain following mastectomy and breast reconstruction • Incidence of pain • 31% with mastectomy alone • 49% with mastectomy and reconstruction • With implants – 53% • Without implants – 30% • Wallace MS, Wallace AM, Lee J, Dobke MK. Pain after breast surgery: a survey of 282 women. Pain. Aug 1996;66(2-3):195-205.
Capsular contracture • Immune response to the foreign object • Tightly woven collagen fiber capsule tightnens and squeezes the implant • Painful and disfiguring • Baker capsular contracture scale • Grade I — the breast is normally soft; appears natural • Grade II — the breast is a little firm, appears normal • Grade III — the breast is firm and appears abnormal • Grade IV — the breast is hard, painful to the touch, and appears abnormal
Axillary web syndrome Also known as cording • Tight fibrous cords in the axilla that can extend along the arm to the antecubital fossa and forearm • Believed to be due to disruption of lymphatic vessels and veins • Typically self-limited but may persist, cause pain and tightness
Post-mastectomy syndrome • Associated signs may include: • Visible muscle spasms • Myokymia • Muscle atrophy • Muscle weakness • Radiation changes • Capsular contracture • Limited ROM • Edema/lymphedema • Cording • Tenderness • Disfigurement
Possible etiologies of post-mastectomy pain • Axillary lymph node dissection • Sentinel lymph node dissection1 • Intercostobrachial nerve injury/entrapment • Axillary hematoma post surgery • Severe acute post-operative pain Miguel R, Kuhn AM, Shons AR, et al. The effect of sentinel node selective axillary lymphadenectomy on the incidence of postmastectomy pain syndrome. Cancer Control. Sep-Oct 2001;8(5):427-430.
Possible etiologies of post-mastectomy pain • Phantom breast pain • May affect 23% of patients • Neuroma formation • Focal area of sensitivity commonly along borders of incision • Rule out local recurrence first • Incisional pain, scar tissue adherence
Post-mastectomy syndrome – additional etiologies • Uncontrolled dystonic muscle spasms and hypertonicity of the chest wall musculature • Tissue ischemia and nerve compression • Pectoralis • Serratus anterior • Latissimusdorsi
Post-mastectomy Syndrome Risk Factors • Younger age • Unmarried • Type/extent of surgery • Radiotherapy • Chemotherapy • Preoperative anxiety • Severe postoperative pain • Greater postoperative analgesic use Tasmuth T, von Smitten K, Hietanen P, Kataja M, Kalso E.

Post-mastectomy syndromePsychosocial factors • Additional risk factors for persistent pain after breast cancer surgery • Catastrophizing • Anxiety • Depression • Somatization • Sleep Quality Schreiber, K. L., et al. (2014). "Predicting, preventing and managing persistent pain after breast cancer surgery: the importance of psychosocial factors." Pain Manag4(6): 445-459.
Post-mastectomy syndromeImpact on Psychosocial Functioning • Chronic pain affects lives • slightly: 50% • at least moderately: 25% • Limited activities due to pain: work, exercise, sleep, socializing, intimacy • Greater psychological or psychiatric morbidity, depression and anxiety Tasmuth T, von Smitten K, Hietanen P, Kataja M, Kalso E.
