Abstract: This single‐institution experience evaluated the use of bioimpedance spectroscopy to facilitate early detection and treatment of breast cancer‐related lymphedema (BCRL) in a cohort of 596 patients (79.6% high risk). Seventy‐three patients (12%) developed an elevated L‐Dex score with axillary lymph node dissection (P < .001), taxane chemotherapy (P = .008), and regional nodal irradiation (P < .001) associated. At last follow‐up, only 18 patients (3%) had unresolved clinically significant BCRL requiring complete decongestive physiotherapy. This rate of BCRL is lower than reported in contemporary studies, supporting recent NCCN guidelines promoting prospective screening, education and intervention for BCRL. [ABSTRACT FROM AUTHOR]

With improved outcomes following treatment of breast cancer, chronic toxicities including breast cancer related lymphedema (BCRL), gain increased significance with limited evidence-based guidelines present. This review attempts to summarize data addressing these concerns and provides recommendations based on currently published data. Substantial differences exist in rates of BCRL reported in the literature ranging from less than 5% to 65% based on locoregional therapy. Based on recent data, early diagnosis of BCRL appears critical and requires careful attention to patient risk factors and the use of newer diagnostic tools. Initial treatment with decongestive lymphatic therapy/compressive stockings can provide significant improvement in patient symptoms and volume reduction of edematous extremities. At this time, consensus recommendations for disease classification, diagnostic testing and treatment are still lacking. Awareness of the frequency of this toxicity is now important as more accurate clinical aids have become accessible to diagnose the condition at an earlier stage allowing timely intervention providing the opportunity for treatment strategies to be more effective.

Although two-thirds of invasive breast cancers and half of non-invasive breast cancers are amenable to lumpectomy, only about 70% of such patients choose breast conservation. Of that group, up to one-third do not follow-up with radiation therapy despite it being clinically indicated. The reasons include the patient’s and surgeon’s attitude toward breast conservation as well as the inconvenience and distance of a suitable radiation facility. The advent of shorter courses of radiation therapy may encourage more patients to seek adjuvant therapy. An increasingly popular and more convenient alternative to traditional whole-breast radiation therapy in patients with early-stage breast cancer is accelerated partial breast irradiation (APBI), for which the American Society of Breast Surgeons and the American Brachytherapy Society have promulgated guidelines for candidate selection. Although several methods are emerging, the most widely used brachytherapy technique utilizes the MammoSite single-catheter balloon brachytherapy device. In a best practices symposium convened in 2006, breast surgeons from academic and community practices with extensive experience in balloon brachytherapy developed general guidelines for integrating APBI into a breast surgical practice. Important considerations include patient age, histology, tumor location and size, and breast size. Thoughtful lumpectomy planning is essential to optimize balloon placement. Real-time sonographic guidance is essential as the surgeon should attend closely to volume excised and cavity shape. A cavity evaluation device can act as a place holder while patient suitability for APBI is considered. Many breast surgeons expert in this procedure insert the balloon catheter in the office either through a de novo skin entrance site removed from the lumpectomy incision or through the original incision. Optimally, insertion occurs within 2–3 weeks after lumpectomy. Close and continual communication with the radiation oncologist is essential to assure optimal outcomes. In this review, several key aspects of a successful APBI program from a surgeon’s perspective as well as a consensus panel from a best practices symposium on the topic herein are highlighted.

Breast sentinel lymph node biopsy is becoming more common. However, the best injection technique is not well established. Currently the gold standard is peritumoral injection. However, for upper outer quadrant tumors there is considerable axillary “shine through” which makes the identification of the radioactive sentinel lymph node difficult. We undertook a study to compare an injection in Sappey's subareolar plexus to the gold standard of peritumoral injection. Between December 1997 and March 1998, 85 patients with breast cancer were enrolled in the study. All patients were injected with 2 cc of normal saline containing 1.0 mCi of unfiltered technetium sulfur colloid in Sappey's subareolar plexus in the clock position of the breast cancer. In the operating room the patients underwent a peritumoral injection of 5 cc of 1% isosulfan blue. All blue and radioactive lymph nodes were identified and removed. The majority of the tumors were in the upper outer quadrant and were diagnosed by core biopsy. Only half of the patients had palpable tumors and approximately 25% had previous upper outer quadrant biopsy incisions. Peritumoral blue dye injection yielded an identification rate of 94%, with 99% of these being blue and radioactive. Three patients had radioactive lymph nodes with no blue lymph nodes identified. One of these patients had a micrometastasis. Injection in Sappey's subareolar plexus in the clock position of the tumor drained to the same sentinel lymph node as peritumoral injection. This injection technique solved the two major problems confronting the wide adoption of sentinel lymph node biopsy for breast cancer staging. First, it eliminates axillary “shine through” which will allow nonspecialist surgeons to more easily identify the radioactive axillary sentinel lymph node. Second, it allows for easier isotope injection by the technician or nuclear medicine physician, by eliminating the need for three-dimensional localization.... [ABSTRACT FROM AUTHOR]
