Abstract

Background

Breast cancer diagnosed at a young age is often associated with aggressive biology, advanced stage, and unfavorable prognosis. The median age of breast cancer diagnosis in Indonesia is younger (48 vs. 68 years-old in Europe) with a relatively higher proportion of patients younger than 40 years old. Although prognosis and outcome of young breast cancer are well studied in developed nations, research evaluating biological characteristics, delivered treatment, and clinical outcomes is very limited in Indonesia.

Methods

We analyzed all breast cancer patients who underwent surgery at Dr. Sardjito Hospital, Indonesia, in 2012–2017. Details of pathology profiles, treatment administrated, and outcomes, as well as reproductive factors among patients younger than 40 years old, were collected and analyzed. Kaplan-Meier curve was used to assess conditional survival based on baseline characteristics.

Results

From the total of 1259 breast cancer patients (median age 51 years), 144 (11.4%) were younger than 40 years old (median age 37 years). Of these young patients, 19 (13.2%) were bilateral and 92 (64%) were diagnosed in advanced stages (stages IIIA-C and IV). Median tumor diameter was 5.5 cm and nodal infiltration was present in 73%. Distant metastasis was found in 16% at the time of diagnosis. Moderate and poor differentiation of tumor were 20.8 and 78.5%, respectively, and lymphovascular invasion was found in 90.3%. Around 40% were hormone receptor-positive, 30.6% human epidermal growth factor receptor 2 positive, and 38.2% triple negative. Patients underwent radical surgery in 121 cases (84%) and breast conserving surgery in 7 cases (4.9%). Adjuvant chemotherapy was administrated in 68% and hormonal therapy in 34%. Progression-free survival was significantly shorter in patients with advanced stage, skin and chest wall involvement (T4), positive lymph node infiltration, positive hormonal receptor, and triple negative subtype (log-rank Mantel-Cox tests, p < 0.05).

Conclusion

We found a high frequency of young breast cancer with biologically more aggressive tumors, late diagnosis, frequent relapse, and poor prognosis. Further actions to improve clinical management and meet psychosocial needs in young breast cancer patients are warranted.
Footnotes
1
mSBR is modified Scarff Bloom Richardson grading system (also known as Nottingham system) in which tumor is semi-quantitatively assessed according to percentage of tubule formation (score 1–3 for 75%, 10–75, and < 10%), nuclear polymorphism (score 1–3 for uniform small cells, moderate variation, marked variation), and mitotic counts per 10–40 fields (score 1–3 for 0–5, 6–10, and > 11). The sum of the score determines the grade: Grade 1 [35], Grade 2 [6, 7], Grade 3 [8, 9]. (REF #10)
