Older patients have been frequently excluded from clinical trials in view of their dismal prognosis and low tolerability of chemo-radiotherapy treatments, therefore they were underrepresented in the past oncological literature. Controversies in the use and dose of RT and in the administration of chemotherapeutic agents have not been solved by the small retrospective studies conducted so far. It appears reasonable that an aggressive treatment with surgery, full dose RT and, possibly, chemotherapy should be applied to patients with good performance status, preserved cognitive functions and no relevant comorbidities, although in the absence of randomised studies the balance of benefits and side effects of integrated treatments remains controversial. Patients with low performance status and/or serious comorbidities, unable to undergo surgery, may receive a shorter RT plan, or even no treatment at all, in consideration of the rapid course of their disease which may be shorter than the hypothetical benefit of any specific treatment.

However, the heterogeneity of breast cancer is such that within a population individual patients derive variable benefit. There is therefore a need for predictive molecular factors in order that treatment can be individualised. This review describes the roles of HER-2, epidermal growth factor receptor (EGFR), oestrogen receptor (ER)/progesterone receptor (PgR), Ki67, Bcl-2, p53 and gene expression profiling in predicting responses to endocrine, cytotoxic and biological therapies. ER and PgR remain the only well-established predictive markers of responses to endocrine therapy, although HER-2/neu has an emerging role in this area and in choice of adjuvant chemotherapy. There are considerable methodological difficulties in identifying useful predictive factors but on the basis of current evidence other biomarkers add little additional information. The development of targeted therapies means that the molecular targets themselves may become useful predictive factors for directing use of these therapies. HER-2 already has an established role in this area, but the role of EGFR requires further elaboration. The use of DNA microarrays to assess gene expression profiles may revolutionise our ability to predict responses to therapy.</p>","PeriodicalId":79489,"journal":{"name":"Forum (Genoa, Italy)","volume":"12 1","pages":"19-32"},"PeriodicalIF":0.0,"publicationDate":"2002-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22286611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
