Breast cancer is one of the most commonly diagnosed types of cancer among women in Canada. Much health sciences research has examined this topic. The importance of formal and informal social support in managing breast cancer has received particular attention, but research with immigrant women has
Male breast cancer (BC) represents an individual subtype of BC, with therapeutic procedures based on female BC therapy results. The present study evaluated the parameters currently used for the characterization and therapy of male BC, and their association with disease-free (DFS) and overall
We aimed to study the prevalence of Hypoxia inducible factor-1α (HIF-1α) P582S and A588T polymorphisms in a Portuguese breast cancer population and its effect on the transcriptional activity of HIF-1α in MCF7 breast adenocarcinoma cells. We performed a polymerase chain Reaction--restriction fragment
BACKGROUND
Breast conservative treatment (BCT) is safe when it is performed in association with radiotherapy. The number of referral for BCT has increased, and it has become an important treatment modality. Patients who undergo BCT present some characteristics that are associated with better quality
Since the first studies reporting the TP53 p.R337H mutation as founder mutation in Southern and Southeastern Brazil, there has been controversy on its origin. Preliminary analysis of a small subset of Brazilian mutation carriers revealed that the haplotype incided on a Caucasian background. The vast
The c.156_157insAlu BRCA2 mutation has so far only been reported in hereditary breast/ovarian cancer (HBOC) families of Portuguese origin. Since this mutation is not detectable using the commonly used screening methodologies and must be specifically sought, we screened for this rearrangement in a
OBJECTIVE
The aim of this study was to analyse the psychometric properties of the Portuguese version of the body image scale (BIS; Hopwood, P., Fletcher, I., Lee, A., Al Ghazal, S., 2001. A body image scale for use with cancer patients. European Journal of Cancer, 37, 189-197). This is a brief and
This paper presents the process of translation and cultural adaptation into Portuguese of the McGill Illness Narrative Interview - MINI, an interview protocol that is used to research meanings and modes of narrating illness experiences, tested, in the Brazilian context, for psychiatric and
Glutathione S-transferases are a superfamily of multifunctional enzymes that play a key role in Phase II metabolism, detoxifying therapeutic drugs, and various carcinogens by conjugation with glutathione. We undertook a case-control study in Central-Eastern Portuguese population to evaluate the
Glutathione-S-transferases (GSTs) are a super-family of phase II metabolizing enzymes that catalyse the detoxification of a large range of endogenous and exogenous toxic compounds, playing an important role in protecting cells against damage, through glutathione conjugation with electrophilic
The purpose of this study was to evaluate the role of polymorphisms in DNA repair genes as genetic indicators of susceptibility to familial and sporadic breast cancer. We analysed DNA samples from 285 breast cancer patients and 442 control subjects, for XRCC1 Arg399Gln, XPD Lys751Gln, RAD51 G135C
Oncoplastic Breast Surgery (OPBS) is becoming an integral part of breast cancer management, but few surgeons have received formal training in these techniques. An International Symposium has recently debated the key issues which impact on training and specialisation in OPBS, as well as patient
Breast cancer (BC) is the most frequent malignancy in Portuguese women, and more than half of the registered cases live in the south of the country. The main of this study was to characterize patients with locoregional and metastatic incident BC living in the Southern Portuguese and Madeira regions
BACKGROUND
A contemporary US study showed an increase in the use of chemotherapy in the last decade for some patients with stage-I breast cancer; with a rise in more intensive regimens, and declining use of anthracyclines. Nevertheless, there is still uncertainty on the absolute benefit of
BACKGROUND
When evaluating a quality-of-life questionnaire (QLQ), many validation studies do not correlate quality-of-life scores with objective measurements of complications associated with treatment.
METHODS
We performed a cross-sectional observational study with 300 patients submitted to
