Background: Breast cancer is becoming more important in Asia since it affect the younger age group. Question arises whether it is safe for breast lesions to be left in-situ if all the elements in triple assessment are benign. The aim of this study is to audit all the excision biopsies of breast lumps done in the University Malaya Medical Centre (UMMC), to review the association of age with the type of pathological finding and to evaluate the rate of carcinoma in these biopsies. Methods: We conducted a retrospective study of all women who had excision biopsy of a breast lump in the University Malaya Medical Centre from January 2005 to December 2006. All patients with malignant preoperative biopsies were excluded. Results: Of 717 lesions in 664 patients, 459 (64%) were fibroadenoma, 114 (15.9%) were fibrocystic disease, 20 (2.8%) were phylloides tumour, 27 (3.8%) were papilloma, 59 (8.2%) were malignant and 38 (5.3%) were of other pathology. Of the 717 open biopsies, 449 (62.6%) had fine-needle aspiration cytology (FNAC), 31 (4.3%) had core needle biopsy (CNB), while 14 (2.0%) had both FNAC and CNB done prior to excision biopsy. 251 (35%) had neither FNAC nor CNB. The incidence of fibroadenoma decreased with increasing age and the incidence of fibrocystic changes and papilloma increased with increasing age. There was no association of age with phylloides tumour. The incidence of unexpected malignancy increased with increasing age. The incidence rates were 0.3%, 4.5%, 19.4%, 29.7% and 29.6% for the age group below 30, 30-39, 40-49, 50-59 and above 60 years of age respectively. Of the 59 malignant lesions, FNAC was performed on 47 (79.7%) and CNB on 16 (27.1%). 9 had both FNAC and CNB and 3 had neither FNAC nor CNB. Out of the 56 lesions where FNAC/CNB were done, 23 (41.1%) were reported as benign, 20 (35.7%) as suspicious, 4 (7.1%) as atypical, 5 (8.9%) as inadequate, 2 (3.6%) as equivocal and 2 (3.6%) as lymphoid lesions. Out of the 23 prior biopsies reported as benign, 22 were in the age group above 40. Conclusions: In conclusion, the rate of unexpected malignancy in open biopsies increases with age. It is recommended that all women above the age of 40 presenting with a palpable breast lump or a suspicious non-palpable abnormality on screening mammogram to have their lump excised even though the lump is benign on FNAC or CNB. However, women age of 30 to 39 should also have the lump excised in the presence of other risk factors such as family history of breast cancer.

This study validates The Malay Version of The Inventory of Socially Supportive Behaviour. Methods: The psychometric properties of the ISSBMalay Version were examined on sixty-eight women who were Malay native speakers and diagnosed with breast cancer. Respondents answered the questionnaire at three weeks and ten weeks following surgery for breast cancer. Results: The Malay Version of ISSB showed excellent internal consistency (Cronbach’s alpha=0.96). Test-retest Intraclass Correlation Coefficient (ICC) was 0.03. Small mean differences were observed at test-retest measurement with Effect Size Index 0.18. Conclusion: The Malay Version of the ISSB could be an appropriate tool to measure the supportive behavior of the Malaysian population.

The aim of this study is to assess tissue and serum prostate-specific antigen (PSA) in breast lesions; to compare tissue PSA with serum PSA; to compare tissue PSA in benign and malignant lesions and to compare PSA with known prognostic factors in breast carcinoma. Tissue PSA immunoreactivity in twenty women with breast carcinoma was compared with PSA in twenty-three women with benign breast lesions. Tissue PSA was also compared with known prognostic indicators such as tumour size, axillary nodal status, histological type, histological grade, oestrogen receptor status, progesterone receptor status and c-erbB-2 oncoprotein over-expression. Serum free PSAlevels from these women were measured pre- and post-operatively and an attempt was made to correlate serum PSA with tissue PSA expression. 40% and 43% of malignant and benign breast lesions respectively showed tissue PSA immunoreactivity. No significant difference was observed in the tissue PSA expression between these two groups as also between tissue PSA and known prognostic indicators. As serum PSA levels were below the detection limit (< 0.004 ng/ml) in all except two benign cases, no statistical evaluation was done for the latter. Tissue PSA expression did not correlate with other prognostic markers and detectable serum PSA levels were present in too few cases for statistical analysis. Although no definitive conclusion is possible in this preliminary study regarding the role of PSA in breast disease, it stimulates interest in further research in this direction.

Neuroendocrine carcinomas of the breast are uncommon tumors known to occur in the elderly. While focal neuroendocrine differentiation may be noted in many ductal and lobular carcinomas, the term neuroendocrine carcinoma is to be applied when more than 50% of the tumor shows such differentiation. This case report details the cytological features of a neuroendocrine carcinoma that was encountered in our hospital. The fine needle aspiration (FNA) smears showed discohesive polygonal cells with abundant cytoplasm, many of which contained eosinophilic granules located at one pole. Histology of the mastectomy and axillary lymph nodes specimen from this patient showed features of neuroendocrine carcinoma--solid type, with metastasis, confirmed with immunohistochemistry. The patient is disease free seven months after surgery. This case highlights the need to closely observe cytological details to identify this rare tumor that may otherwise appear to be invasive duct carcinoma--not otherwise specified on FNA. The implications of diagnosing neuroendocrine differentiation for prognosis and management are also discussed.

Metastasising ability connotes one of the most important life-threatening properties of malignant neoplasms. Recent studies indicate that CD44 proteins, multifunctional cell adhesion molecules which contribute to "homing" of lymphocytes to lymph nodes as well as cell-cell and cell-matrix interactions, are potential markers of tumour progression. However, whether CD44 expression by human tumours contribute to increased metastatic risk remains controversial. In an attempt to clarify its role in breast cancer, we have investigated the correlation between CD44 expression by breast carcinoma and the presence of axillary lymph node metastases. CD44 expression was detected using a standard immunoperoxidase method on formalin-fixed, paraffin-embedded, primary infiltrating ductal breast carcinoma tissues taken from 60 female patients who underwent mastectomy with axillary node clearance. Tumours were graded according to the modified Bloom and Richardson criteria. 62% of patients had histologically-proven lymph node metastasis. 40% of primary cancers exhibited cytoplasmic membrane immunopositivity for CD44. 46% of primary tumours which have metastasied to axillary lymph nodes were CD44 positive whereas 30% of tumours which have not metastasised expressed CD44. CD44 positivity was expressed by 20% of grade 1, 31% grade 2 and 58% grade 3 tumours. Our results suggest that CD44 may have a role in the progression of breast cancer and emphasise the need to investigate its interaction with other mechanisms of cancer advancement.
