METHODS: A 70-year-old female patient was found to have a right breast lump for over 2 years. On January 3, 2023, a core needle biopsy of the right breast lump was performed, and the pathology report indicated invasive carcinoma. Subsequently, on January 17, 2023, the patient underwent right breast-conserving surgery, sentinel lymph node biopsy, and right axillary lymph node dissection. The postoperative pathological staging was determined as stage IIB. The patient received chemotherapy, radiotherapy, and endocrine therapy. At present, nearly one year after the surgery, no obvious signs of metastasis have been observed in the follow-up examinations, but the long-term prognosis is still unknown.
CONCLUSIONS: There is a need for increased focus on the matter of tumor deposits in the lymph node drainage region, as well as a requirement for further clinical investigation to ascertain the relevance of tumor deposits in the prognosis of individuals with breast carcinoma.
