Prognosis of BRCA-associated breast cancer: a summary of evidence

Bordeleau, L., Panchal, S., Goodwin, P.·2010·Breast Cancer Research and Treatment

Abstract

The purpose of the study is to review the clinical studies relevant to the prognosis and prognostic associations of BRCA1- and BRCA2-associated breast cancers. Reports of relevant studies obtained from a MEDLINE search and references from these articles were critically reviewed. A number of methodologic limitations have been identified in the early studies. More recent studies have failed to demonstrate, for the most part, a significant overall survival difference between BRCA-associated breast cancers and sporadic breast cancers. The risk of in-breast tumor recurrence also appears to be similar in the first 5 years following a breast cancer diagnosis with apparent increase in the risk after 5 years in one study. Many in-breast tumor recurrences are now considered to be second primary breast cancers. There is a significant increase in the risk of contralateral breast cancers in BRCA mutation carriers with an estimated 10-year risk ranging from 20-40%. The prognosis of BRCA-associated breast cancers appears to be similar to that of sporadic breast cancers based on the current literature. Future data from large prospective cohort studies will be of interest.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The risk of contralateral cancer was significantly higher 5 to 10 years after first diagnosis in BRCA1/2 mutation carriers, ranging from 20 to 42%, compared with 5% and 6% in non-carriers.

    “Bordeleau et al. [14] found that the risk of contralateral cancer was significantly higher 5 to 10 years after first diagnosis in carriers, ranging from 20 to 42%, compared with 5% and 6% in non-carriers.”
  • Women with a BRCA1/2 genetic mutation who have been treated for breast cancer are at increased risk of having a local recurrence or a second primary cancer.

    “In addition to having an increased risk of developing a first breast cancer, women with a BRCA1/2 genetic mutation and who have been treated for breast cancer are also at an increased risk of having a local recurrence or a second primary cancer.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
