Variant 1: 57-year-old woman, triple negative IDC, status postmastectomy: 3.5 cm inner quadrant primary, 7/12 LN (+). Focally positive deep margin. PET (+) IMN and supraclavicular nodes. Adjuvant anthracycline and taxane, with normalization of PET findings. Metastatic workup negative.
Variant 2: 55-year-old woman with neglected primary. Large, fungating lesion and matted axilla. ER (–)/PR (+), Her2 (–). Metastatic workup negative. Not operable after three chemo regimens, including anthracyclines and taxanes.
Variant 3: 40-year-old woman, 4 cm primary with diffuse suspicious microcalcifications in breast, direct skin invasion, satellite skin nodule, matted axilla (N2), ER (+)/PR (–), Her2 (–). Metastatic workup negative.
Variant 4: 80-year-old woman, 4 cm primary, direct skin invasion, satellite nodule, matted axilla (N2), strongly ER/PR (+), Her2 (–). Metastatic workup negative. Medically fit.
Variant 5: 45-year-old premenopausal woman, 4.5 cm IDC left breast, ER/PR (–), Her2 amplified, PET (+) in breast, axilla, and medial infraclavicular fossa. Palpable nodes in high axilla. Metastatic workup negative. Patient desires breast conservation.
Variant 6: 38-year-old woman, T4 inflammatory, N1 disease, no response post 3-cycle multidrug chemotherapy. ER/PR (–), Her2 (–). Metastatic workup negative.
Variant 7: 50-year-old woman, T3N2M0 disease, with clinical CR post 4-cycle multidrug chemotherapy. ER/PR (–), Her2 (–). Does not desire BCT.
Variant 8: 50-year-old woman, stage T3N2M0 disease, with good clinical response following 4 cycles of multidrug neoadjuvant chemotherapy. She does not desire BCT and consents for mastectomy with reconstruction. Pathology from the mastectomy confirms ypT0N0M0 disease.
Variant 9: 42-year-old woman with clinical stage T2N1M0 Her2 amplified left breast cancer. She undergoes a mastectomy with reconstruction and axillary dissection. Pathology notes 3.5-cm invasive cancer mastectomy margins are negative and 11/12 (+) nodes. Patient will receive chemotherapy and trastuzumab for 1 year.
