Prognostic and predictive factors in breast cancer.

The goal of personalised medicine is a top priority for current clinical research and in the UK this has been recognised by the development of a Stratified Medicines Initiative, which is being led by the Medical Research Council. Although oncology is unique among disciplines in its personalisation, being markedly influenced by somatic mutations, it is expected to be in the vanguard of developments under this initiative. Given that breast cancer is the most advanced malignancy in terms of biomarkers and molecular signatures used for stratification of treatment, it is a key disease for inclusion in this initiative. The communications in this section of the meeting report are therefore particularly timely. The papers are separated to deal with two main issues. Firstly, what are the opportunities, constraints and requirements for the establishment of predictive and prognostic factors that have clinical utility, and are there new ways in which we can integrate these into a pathological understanding of the disease? Secondly, does molecular profiling currently offer any more than tumour histology or basic immunochemistry for clinical application?

Around women develop breast cancer worldwide. In the U. Treatment of early breast cancer is surgical, comprising breast conserving surgery followed by radiotherapy for small unifocal tumours, or mastectomy for larger or multifocal tumours. Survival of patients with breast cancer depends on two different types of prognostic factors: In women with a tumour that has adverse features predicting early recurrence i. Chemotherapy is given to pre-menopausal women for oestrogen receptor negative post-menopausal breast cancer, whereas hormone therapy is reserved for oestrogen receptor positive cancer. The use Sexual Harrassment Classes hormone therapy and chemotherapy has Prognostic Factors For Breast Cancer aided by factors predicting the likelihood of response, e.

If you have breast cancer, you may have questions about your prognosis. Prognosis and survival depend on many factors. Only a doctor familiar with your medical history, the type, stage and characteristics of your cancer, the treatments chosen and the response to treatment can put all of this information together with survival statistics to arrive at a prognosis. A prognostic factor is an aspect of the cancer or a characteristic of the person that the doctor will consider when making a prognosis. A predictive factor influences how a cancer will respond to a certain treatment. Prognostic and predictive factors are often discussed together. They both play a part in deciding on a treatment plan and a prognosis.

The purpose of this study was to analyze the prognostic and predictive factors that relate to locoregional or distant recurrences in breast cancer patients who have been treated at the National Cancer Institute of Mexico. Breast cancer BC is the most common cancer among American women, with more than , new cases diagnosed each year. In Mexico in , there were 16, reported hospitalizations for breast cancer and 4, breast cancer-related deaths. The introduction of mammography screening protocols in recent decades has facilitated the detection of breast cancer at increasingly earlier stages. This wide range of reported results is probably due to inadequate axillary dissection, incomplete surgical technique, or suboptimal systemic treatment [ 3 ]. The involvement of the axillary lymph nodes LNs is the most important prognostic factor for recurrence in the early stages of BC according to the literature. Patients with cancer-positive LN have been reported to have a four to eight times higher mortality rate in comparison to patients with negative lymph nodes. There is also a direct correlation of positive LN status with the risk of distant recurrence [ 4 ].

Identify prognostic factors used to determine the risk of recurrence and death for a patient with early-stage breast cancer. Identify predictive factors used to determine the optimal therapy for a patient with early-stage breast cancer. Breast cancer is the most common malignancy among American women. Due to increased screening, the majority of patients present with early-stage breast cancer.

Author information: There are two major questions regarding systemic therapy of breast cancer: Firstly, which patients should be treated, and secondly, how should these patients be treated? Prognostic factors aim to foresee the outcome of patients irrespective of treatment while predictive factors intend to assess the outcome of patients receiving a certain systemic therapy and thus are intimately associated with sensitivity or resistance to therapy. Ideally, a predictive factor is also a therapeutic target as it is the case with estrogen receptor ER or HER In order to avoid over- as well as under-treatment, it is advisable to select the appropriate treatment strategy on the basis of a careful risk assessment for each individual patient. These multigene profiles offer new insights in breast cancer biology, like the important role of the tumor-associated immune system.
