Management of Bandlike Nodularity in Previously Treated Breast Cancer

Immediate Diagnostic Workup

The American Cancer Society recommends measuring and documenting the exact size and location of the bandlike nodularity, noting its relationship to the previous surgical site 1
Clinical assessment should include evaluating for skin changes, nipple retraction, or fixation to underlying structures that would suggest invasive disease 1
Palpation of regional lymph nodes (axillary, supraclavicular, infraclavicular) is necessary for evidence of nodal involvement 1
Bilateral diagnostic mammography should be obtained within 3 months if not recently performed, including magnification views to characterize any microcalcifications or architectural distortion 1, 2
The National Comprehensive Cancer Network recommends considering breast MRI if mammography and ultrasound are inconclusive, as MRI has 70% sensitivity for identifying occult breast lesions in challenging cases 3

The National Comprehensive Cancer Network suggests that surgical excision with wide margins (≥1 cm tumor-free) is the primary treatment for recurrent invasive carcinoma, with mastectomy required if negative margins cannot be achieved with partial mastectomy 6, 2
Sentinel lymph node biopsy or axillary dissection should be performed for invasive disease, as nodal status guides systemic therapy decisions 7, 8, 2
Radiation therapy to the chest wall should be considered after resection of local recurrence, though this remains somewhat controversial (category 2B recommendation) 6

At 82 years, treatment intensity must balance oncologic benefit with quality of life, considering comorbidities and functional status 10, 9
For hormone receptor-positive disease in elderly patients, endocrine therapy alone may be appropriate in select cases rather than aggressive multimodality treatment 10

The American Cancer Society advises against assuming palpable findings are benign scar tissue in a patient with prior breast cancer—tissue diagnosis is mandatory 1
Inadequate tissue sampling should be avoided—ensure core biopsy obtains sufficient material for both histology and receptor testing if malignancy is found 5
Delaying workup based on patient age is not recommended—while treatment may be modified for an 82-year-old, diagnosis should proceed expeditiously 10
