Pure tubular carcinoma of the breast: a case series
1Surgical Oncology Department, Salah Azaiez Institute of Oncology, Tunis, Tunisia.
Background:
Pure tubular breast carcinoma is a rare and well-differentiated tumor with high survival and low local recurrence rate. Our study aims to determine the clinical, radiological, appropriate management, and prognosis of this carcinoma.
Materials And Methods:
A review of Salah Azaiez institute registry from 2004 to 2019 was performed including seven cases of PTC of the breast.
Results:
Clinical-pathologic features and outcomes were analyzed. The median follow-up was 3 years. In our study, we found that the cohort presented more frequently with pT1 disease and pN0 disease. Conservative surgery was more frequently indicated (five cases). All patients had hormone-receptor positivity and Human Epidermal growth factor Receptor 2 (HER2) negativity. The majority of tumors had a molecular profile luminal A and a low-grade SBR. In one case we found axillary lymph node metastasis. Adjuvant radiotherapy was indicated in all cases of breast conservation and in only one case of radical surgery. One patient received chemotherapy. The mean follow-up was 4 years. We did not find any local or distant recurrence in our study.
Conclusion:
PTC showed an excellent prognosis with a low SBR grade, a molecular profile luminal A, and a low incidence of recurrence.
