Abstract
Background: Breast cancer is the second most common cancer in the world; the most frequent cancer among women, and leading cause of cancer death in females worldwide. Aim: The aim of the study is to study the pattern and treatment modalities for breast cancer patients who registered in Tripoli University Hospital from 2003 to 2018. Patients and Methods: A retrospective, cross‑sectional study was conducted at the Oncology Department of Tripoli University Hospital. A convenience sample of 1000 breast cancer patients from 2003 to 2018 was chosen. Demographic, clinic‑pathological characteristics, and treatment modalities data were analyzed by SPSS program version 20. Results: Of 1000 breast cancer patients, there were 984 (98.4%) females and 16 (1.6%) males, mean age was 46.1 ± 11.7 years old, most of them from western region. Majority (64.3%) of female were early age at menarche and 46.2% not breastfed. Positive family history of first degree was 28.8%. The left side presentation was the predominant (60.3%); half of the cases were in Stage II. Invasive ductal carcinoma was diagnosed among 62.5% of the cases and 47% of them were in Grade III. Positive estrogen receptor recorded in 73.8% of cases compared to 69.5% positive progesterone. Furthermore, 76.8% of patients had human epidermal growth factor receptor 2 negative and 78.4% of cases had high Ki‑67 level. Regarding management, a combination of surgery, radiation, chemotherapy, and hormonal were provided to 58% of cases, 45.5% of patients who received chemotherapy were treated with FEC regimen. Hormonal therapy was given to 67.7% and tamoxifen is the most drugs used. Conclusions: The frequency is higher among younger age (<50 years), early age at menarche, breastfed less than a year, nearly half presented in late Stage (III, IV), invasive ductal carcinoma is predominant histopathological type, most cases were HER2 negative and high Ki‑67 expression. More efforts toward primary prevention and early detection are recommended to reduce locally advanced breast cancer.
