Background: Breast cancer is the most commonly diagnosed and the leading cause of cancer death among females worldwide. The rate of breast cancer incidence among Iranian women is 17% of all cancers, it has been ranked first in Iran. This study aimed to investigate the factors affecting axillary lymph node involvement in female patients with breast cancer.
Methods: A cross-sectional study was conducted on 167 patients with breast cancer diagnosed between March 2012 and March 2015 at Shahid Beheshti of Babol, Shahid Rajaei of Tonekabon and Imam Sajad of Ramsar hospitals. A researcher-made questionnaire was used to collect information on the patients and pathology report of tumor and lymph nodes was completed.
Results: The rate of axillary lymph node involvement was observed in 117 patients (70.1%). Mean age was 49.64±11.62 years in the patients with breast cancer. The highest frequency of lymph node involvement was observed in the 40-49 age group (24%). The average size of tumor was 3.39 cm and the majority of patients had a tumor 2-5 cm (T2) but the most involvement was related to T3 (>5cm). The most common type of cancer and grading were invasive ductal carcinoma (93.4%) and tumor grade 2 (52.1%), respectively. Most lymph node involvement was observed in invasive ductal carcinoma and 85.1% of patients had tumor degree 3. 22.2% of patients with vessels involvement had axillary lymph node involvement. 63% of patients’ tumors had receptors of estrogen and progesterone. A statistically significant association was observed between axillary lymph node involvement and tumor size (P=0.031), tumor type (P=0.007), tumor grade (P=0.011), estrogen receptor (P=0.008) and progesterone receptor (P=0.038).
Conclusion: There was a statistically significant association between axillary lymph node involvement and tumor size, type and grade, estrogen and progesterone receptor status, but there was no statistically significant association between axillary lymph node involvement and age and estrogen as well as progesterone receptor status.
