Histopathological Review of Male Breast Cancer Cases
Journal Title: Medical Science and Discovery - Year 2014, Vol 1, Issue 3
Abstract
Objective: Male breast cancer (MBC) accounts for less than 1% of all breast cancer diagnoses and all cancer cases in men. Methods: We included 33 MBC cases and analyzed histopathological features and survival data. Results: The mean age was 63.5, mean tumor diameter was 3 cm. Central quadrants (69.2%) was most common localization, invasive ductal carcinoma (75.8%) was most common histological subtype. Most of the cases (78.6%) were grade 2. Nipple involvement was noted in 9, tumor necrosis in 9, perineural invasion in 15, dermal lymphatic emboli in 10 cases. Nearly half of the cases (45.5%) showed lymph node metastasis. There was statistically significant relation between lymph node metastasis and stromal lymphocyte response, tumor necrosis (p=0.008, p=0.013) also between grade and dermal lymphatic emboli (p=0.04). Non-tumoral parenchymal findings were columnar cell lesions (CCL), (n: 5) and gynaecomastia (n: 3). Majority of the cases showed estrogen receptor (90.9%) and progesterone receptor (77.2%) positivity. Overall survival analysis showed significant results between grade (p=0.008), lymph node metastasis (p=0.03), dermal lymphatic tumor emboli (p=0.02), nipple involvement (p=0.02) and survival. Conclusions: Our results showed good correlation with literature data in terms of histopathological features and prognostic factors. Confidential data about etiological and prognostic factors will be collected through these reports showing institutional experiences. The significance of CCL in MBC etiology, the impact of intratumoral stromal lymphocyte response, hormone receptor-HER2 status on survival should be clarified in larger series
