Match each of the following patient clinical presentations and breast biopsy findings with the most appropriate definitive surgical management.

  • A 35-year-old woman with a 4.5-cm, rapidly enlarging mobile breast mass; core biopsy shows cellular stroma with leaf-like architecture.Wide local excision with negative margins, without routine axillary lymph node staging
  • A 45-year-old woman with mammographic pleomorphic microcalcifications; stereotactic core biopsy reveals atypical ductal hyperplasia.Surgical excisional biopsy of the lesion to rule out adjacent or occult malignancy
  • A 60-year-old woman with a 1.5-cm unifocal invasive ductal carcinoma; physical exam and axillary ultrasound show no suspicious lymph nodes.Breast-conserving surgery (lumpectomy) with sentinel lymph node biopsy
  • A 55-year-old woman with extensive, diffuse microcalcifications across three breast quadrants; core biopsy reveals high-grade ductal carcinoma in situ (DCIS).Simple (total) mastectomy with concurrent sentinel lymph node biopsy

Cevap

Phyllodes tumor matches with wide local excision without axillary staging. Atypical ductal hyperplasia matches with surgical excisional biopsy. Early-stage, node-negative invasive ductal carcinoma matches with breast-conserving surgery and sentinel lymph node biopsy. Multicentric DCIS matches with simple (total) mastectomy and concurrent sentinel lymph node biopsy.
Each breast pathology has specific surgical indications based on tumor biology and extent of disease. Phyllodes tumors require wide local excision without axillary staging due to hematogenous spread. Atypical ductal hyperplasia requires excisional biopsy due to high upgrade rates to malignancy. Unifocal early-stage invasive breast cancer in clinically node-negative patients is standardly treated with breast-conserving surgery and sentinel lymph node biopsy. Multicentric DCIS necessitates mastectomy (due to the inability to achieve clear margins with lumpectomy) and simultaneous sentinel lymph node biopsy (because mastectomy disrupts lymphatic drainage, preventing later mapping if occult invasive cancer is found on final pathology).

Adım Adım Çözüm

1
Evaluate the clinical presentation of the 35-year-old woman with a leaf-like stromal tumor.
Identified as a phyllodes tumor, which requires wide local excision but rarely metastasizes to lymph nodes.
Phyllodes tumors demand complete excision with negative margins to prevent recurrence, but lack lymphatic spread, making axillary staging unnecessary.
2
Assess the core biopsy finding of atypical ductal hyperplasia (ADH) in the 45-year-old woman.
Recognized as a high-risk lesion requiring surgical excisional biopsy.
Core needle biopsies showing ADH have a high rate of upgrade to malignancy, necessitating complete excision of the lesion for a definitive diagnosis.
3
Determine the surgical management for a 1.5-cm, clinically node-negative invasive ductal carcinoma.
Selected breast-conserving surgery with sentinel lymph node biopsy.
Lumpectomy with radiation is equivalent to mastectomy for unifocal early-stage breast cancer, and sentinel lymph node biopsy is standard for axillary staging in clinically node-negative disease.
4
Determine the optimal surgical approach for multicentric DCIS.
Selected simple mastectomy with sentinel lymph node biopsy.
Multicentric disease cannot be managed with breast-conserving surgery. Sentinel lymph node biopsy is done simultaneously because the mastectomy prevents future lymphatic mapping if an occult invasive cancer is discovered.
