Surgery Journal Club Breast-Cancer Related Lymphedema :A Review of Procedure-Specific Incidence Rates , Clinical Assessment Aids , Treatment Paradigms & Risk ReductionThe Breast Journal , July-August 2012 , Nashville Breast Cancer , Tennessee By : Ahmad Zahmatkesh Mohammadreza Nazemian
Introduction • As the number of women who are long term survivors of breast cancer increases , chronic toxicities such as breast cancer related lymphedema ( BCRL ) gain importance • Purpose of this Review : Summarize the latest studies addressing BCRL in order to provide patients and health care providers with optimal recommendations
Rates of BCRL • Well documented in older randomized breast cancer treatment trials exemplified by NSABP B-04 Trial : * NSABP : National Surgical Adjuvant Breast & Bowel Project
Rates of BCRL • Recent data has emerged that rates of BCRL are predicated on the aggressiveness of treatment : • Breast surgical procedure performed • Method of axillary surgery ( Sentinel LN Vs. Axillary LN Dissection ) • Use and extent of adjuvant radiation therapy • Use of adjuvant chemotherapy
Rates of BCRL • In a Series of over 3000 patients which evaluated for incidence of BCRL after breast conservation (BC) via survey were :
Rates of BCRL • NSABP B-32 Trial demonstrated that rates of BCRL significantly reduced with the use of SLND over ALND , 8% vs. 14% • Coen et al. examined 727 patients who were treated with BCS and WBI with or without regional irradiation and found that rates of BCRL were 2% for tangents alone vs. 9% with regional irradiation • Norman et al. found that patients receiving chemotherapy had an increased risk of developing BCRL with a HR of 1.46
Rates of BCRL • Table 1 - Rates of BCRL by Loco-Regional Therapy
Diagnosis of Lymphedema • With Traditional studies the diagnosis of BCRL in the subclinical phase of disease remain limited and often diagnosed after development of significant BCRL • Improvements in BCRL diagnostic modalities decreased the number of women suffering with the long term complications
Diagnosis of Lymphedema • Traditional Studies : • Arm circumference measurement : • Simple • Lack of standardized measuring points and definition of BCRL , Intra and Inter-Observer variability • Water displacement : • Lacks Sensitivity • Self-assessment
Diagnosis of Lymphedema • New detection techniques : • Bioimpedance Spectroscopy ( BIS ) • Standardized cut-off point • Increased sensitivity and detect BCRL 4 months earlier >> Potential for subclinical detection • Optoelectric Perometry • Increased Sensitivity and Decreased variability
Treatment of Lymphedema • BCRL management involves : • Severity of volume accumulation • Severity of Symptoms • Acute vs. Chronic nature of disease
Treatment of Lymphedema • Treatments include : • Compression therapy : • The efficacy remains controversial • Techniques and Devices : • Compression bandages or garments • Gradient compression devices • Pneumatic compression devices • Multi-modality ( ie., Complex Decongestive physiotherapy ) • Pharmacotherapy : • Benzopyrones : • Decrease fluid volume , Improvement of Subjective Pain , Tightness and Acute inflammation • Diuretics • Selenium
Treatment of Lymphedema • Complex Decongestive physiotherapy • Utilized for more advanced BCRL • Includes : Compression , MLD , Basic Skin care and Exercise • Administered by well-trained therapists • Phase I : Outpatient / Multi-week program of MLD , Short-stretch compression bandaging , Exercise and Proper skin-nail care and preparing patient for phase II • Phase II : At Home / Entails Skin care , Exercise , Self-massage and Use of compression • The Efficacy of CDP has been verified in multiple studies and improved patient’s quality of life as well as decreasing excess arum volume accumulation
Risk Reduction • By Eliminating ALND and not adding regional irradiation , the rates of BCRL may be significantly reduced • By Limiting the number of patients receiving regional irradiation further reduction of BCRL would be seen • By Using new techniques that examine genetic markers in tumors and provide recurrence risk scores , the number of patients requiring chemotherapy will likely decrease so developing of BCRL will reduce • Early Diagnosis at the subclinical stages represent a novel and recently tested method to reduce the risk of BCRL
Discussion • BCRL is more prevalent than generally appreciated even after less morbid axillary procedures ( including SLND ) are utilized • BCRL can be detected earlier when newer diagnostic interventions are applied to prevent the chronic phase of the disease as well as sequelae including infection , ulceration and disfigurement
Discussion • Simple and reproducible assessment aids currently exist and should be used both prior and after local therapies in virtually all “at risk “ patients • Data regarding optimal treatment strategies is limited and controversies do exist but based on the currently available CDP represents a therapeutic modality with significant supporting evidence in patients with clinically detectable BCRL
Discussion • Utilization of new diagnostic modalities may facilitate earlier clinician detection and management of BCRL and have the potential to significantly reduce costs associated with the management of BCRL
