Lymphedema Precautions: Time to Abandon Old Practices?

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 46-year-old premenopausal woman with a body mass index of 21 was found on screening mammography to have a new, approximately 1-cm spiculated mass with associated calcifications in the upper outer quadrant of the left breast. Stereotactic core biopsy showed a focus of invasive duct carcinoma, strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2, with associated ductal carcinoma in situ. Clinical examination revealed no palpable mass or axillary lymphadenopathy. She underwent a left lumpectomy with seed localization and sentinel lymph node biopsy. Final pathology revealed an 8-mm well-differentiated invasive carcinoma without lymphovascular invasion and intermediate grade ductal carcinoma in situ. The margins were clear, and three sentinel lymph nodes were negative for metastasis. The 21-gene recurrence score was 10, suggesting a 7% risk of 10-year distant recurrence with adjuvant endocrine treatment. After the completion of adjuvant radiotherapy (42.50 Gy in 16 fractions to the breast), the patient has returned for a follow-up visit. She is a professional violinist and would like to know what she can do to prevent lymphedema on her upcoming flight to Vienna.

Risk of invasion and axillary lymph node metastasis in ductal carcinoma in situ diagnosed by core-needle biopsy.

The aim of the study was to assess the risk of invasion and axillary lymph node metastasis in patients with ductal carcinoma in situ (DCIS) diagnosed by preoperative core-needle biopsy. The data were used to select criteria for patients in whom sentinel node (SN) biopsy might be indicated. One hundred and seventy-one women with 172 DCIS lesions diagnosed by core-needle biopsy were analysed. Axillary staging was performed by SN biopsy, axillary node sampling, or level 1-2 axillary lymph node dissection. Invasive breast cancer was found in the surgical specimens from 45 tumours (26.2 per cent). Risk factors for invasion were a palpable lesion (odds ratio (OR) 2.95 (95 per cent confidence interval 1.20 to 7.26); P = 0.019), presence of a mass on mammography (OR 3.06 (1.43 to 6.56); P = 0.004), and intermediate (OR 5.81 (1.18 to 28.57); P = 0.030) or poorly differentiated (OR 5.46 (1.17 to 25.64); P = 0.031) tumour grade. Lymph node metastases were found in ten women with DCIS and invasion on final pathology. Factors associated with metastases were age 55 years or less (P = 0.030), invasion of 1.0 cm or more (P < 0.001) and the presence of vascular invasion (P = 0.001). SN biopsy should be considered in women with an initial diagnosis of DCIS on core-needle biopsy who are at risk for invasion; this includes women with a palpable lump, a mass on mammography, and intermediate or poor tumour grade.
