Letter to the Editor regarding the paper by Aurilio et al., A meta-analysis of oestrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 discordance between primary breast cancer and metastases
Sir,We have read with great interest the article in press ofAurilio et al., A meta-analysis of oestrogen receptor, pro-gesterone receptor and human epidermal growth factorreceptor 2 discordance between primary breast cancerand metastases (http://dx.doi.org/10.1016/j.ejca.2003.10.004), which will appear in Eur J Cancer. In the paper,the Authors have performed a meta-analysis of the stud-ies published in the literature concerning the discor-dance rate in oestrogen receptor (ER), progesteronereceptor (PgR) and HER2 status between primarytumour and corresponding relapse. It is well known thata considerable controversy concerns the issue of hor-mone receptors (HRs) expression as well as HER2 sta…
HER2 status in advanced gastric carcinoma: A retrospective multicentric analysis from Sicily.
According to the ToGA trial, HER2 has been shown to be predictive for the success of treatment with trastuzumab in advanced gastric cancer (AGC). A number of studies have analyzed HER-2/neu overexpression in gastric carcinoma and identified the rate of HER2 positivity to be markedly varied. To date, the prevalence of HER2 overexpression in Sicilian people with AGC is unknown. Therefore, in the present study, a retrospective immunohistochemical analysis of HER2 was performed in a cohort of 304 AGC samples that were obtained from the archives of 10 Sicilian anatomopathological diagnostic units in order to verify the positive rate of HER2-positive cases. Furthermore, the characteristics of his…
Morphological and biomolecular characteristics of subcentimetric invasive breast carcinomas in Sicily: A multicentre retrospective study in relation to trastuzumab treatment
Little information from clinical trials is available regarding the efficacy of trastuzumab treatment in subcentimetric breast carcinomas (BCs). The aim of this study was to verify the existence of correlations between HER2 and hormone receptor status, Ki67 values, grade, histotype and node involvement in a cohort of pT1a,b BCs from an area not widely covered by screening campaigns. A total of 410 pT1a,b BC formalin-fixed paraffin-embedded samples collected from eight Sicilian Anatomo-Pathological Units (APUs) were classified according to the WHO classification and tumour grading was established. Estrogen and progesterone receptor status, Ki67 labelling index and HER2 status were available. …

Role of trastuzumab in infracentimetric HER2-positive breast cancer: The southern Italy experience.
e11512 Background: HER2 positive (HER2+) disease is relatively uncommon in early infracentimetric breast cancer (BC) accounting for approximately 10% of cases. Trastuzumab (T) based-adjuvant therap...
