Purpose: Compared to Western societies, breast cancer diagnosis in our region is usually made at a younger age and at a more advanced stage. Breast cancer in younger patients tends to be more aggressive, and may result in a higher likelihood of long-term treatment-related toxicity and unique psychosocial problems. This study highlights the clinicopathological features and treatment outcomes in this age-group in a developing country like ours.
Methods: Consecutive patients aged 40 years or younger with a pathologically confirmed diagnosis of breast cancer treated and followed up at our institution were included. Medical records and hospital databases were searched for patients’ characteristics and treatment outcomes.
Results: A total of 417 patients were enrolled. Median age at diagnosis was 35 (21–40) years. On presentation, 63 (15.1%) patients had metastatic disease, 50 (79.4%) with visceral metastasis. Patients with nonmetastatic disease had poor pathological features, including node-positivity (66.9%), grade III (51.4%), lymphovascular invasion (48.6%) and positive HER2 (31.5%). Breast-conserving surgery was performed on 32.9%, and only 36.5% of women had breast-reconstruction surgery. At a median follow-up of 59 months, 5-year overall survival for the whole group was 72%: 84% for nonmetastatic and 13% for those with metastatic disease. On Cox regression, nodal metastasis (adjusted HR 3.46, 95% CI 1.48–8.10; p=0.004) and grade III disease (HR 1.97, 95% CI 1.14–3.39; p=0.015) were associated with poor outcome.
Conclusion: Adolescents and young Jordanian adults with breast cancer present with more advanced–stage disease and more aggressive pathological features that reflect poorly on treatment outcomes.
