ABSTRACT

Recently, we observed that telomeres of BRCA1/2 mutation carriers were shorter than those of controls or sporadic breast cancer patients, suggesting that mutations in these genes might be responsible for this event. Given the contradictory results reported in the literature, we tested whether other parameters, such as chemotherapy, could be modifying telomere length (TL). We performed a cross-sectional study measuring leukocyte TL of 266 sporadic breasts cancer patients treated with first-line chemotherapy, with a median follow-up of 240 days. Additionally, we performed both cross-sectional and longitudinal studies in a series of 236 familial breast cancer patients that included affected and non-affected BRCA1/2 mutation carriers. We have measured in leukocytes from peripheral blood: the TL, percentage of short telomeres (<3 kb), telomerase activity levels and the annual telomere shortening speed. In sporadic cases we found that chemotherapy exerts a transient telomere shortening effect (around 2 years) that varies depending on the drug combination. In familial cases, only patients receiving treatment were associated with telomere shortening but they recovered normal TL after a period of 2 years. Chemotherapy affects TL and should be considered in the studies that correlate TL with disease susceptibility.

ABSTRACT

The increase in life expectancy in the western world means that we are faced with patients diagnosed with breast cancer in old age with increasing frequency. The management of these cases is a challenge for the oncologist, who must take into account the conditions associated with advanced age and the lack of trials in this population. In this review, we addressed the incorporation of geriatric assessment methods that may be useful in making decisions, the particular biological characteristics of breast cancer in elderly patients and their treatment in both localized and advanced disease. Finally, we collected recommendations based on scientific evidence regarding the monitoring and life-style after finishing treatment (AU)

ABSTRACT

Patients with metastatic breast cancer have a wide number of treatment options, including medical, surgical, and supportive care measures. Treatment decisions are based in predictive and prognostic factors and the informed choice of the patients. SEOM has elaborated these guidelines with evidence-based recommendations for the diagnostic work-up, treatment (chemotherapy, endocrine therapy and targeted therapies) and supportive care for the management of these patient (AU)

ABSTRACT

The following manuscript summarises the content of the Breast Symposium that was held in May 2008 in Barcelona in which four controversies regarding the management of breast cancer were discussed. The design of the symposium included two speakers per controversy, one in favour and one diverging, and the audience had to vote before and after the presentations to assess changes in the participants' views. The four controversies included: (1) the role of non-conventional predictive factors in selecting treatment for breast cancer; (2) the role of surgery in disseminated disease; (3) are taxanes indicated in the adjuvant treatment of patients with lymph-node-negative disease?; (4) is treatment with tamoxifen (TAM) always required after surgery in patients with ductal carcinoma in situ (DCIS)? The symposium concluded with the presentation titled: 'Features of a well designed clinical trial in the adjuvant treatment of breast cancer'.

ABSTRACT

Breast cancer treatment currently requires the joint efforts of a multidisciplinary team to effectively combine chemotherapy, hormone therapy, biological agents, surgery and radiation therapy when needed. To develop such a treatment plan, it is important to know the benefits as well as the potential toxic effects of each therapy. Thus, many patients with early breast cancer complain of collateral adverse events such as fatigue, nausea, vomiting, loss of libido, hot flashes, night sweats or neuropathy due to the complex therapies they are receiving. To date, the treatment of such symptoms is an important issue that greatly affects the quality of life of these patients. In this review, we report the content of a multi-expert meeting where the incidence of and medical approach to some of the most common adverse events encountered during the treatment of patients with early breast cancer were analysed (AU)
