Gradually implemented new biomarkers for prognostication of breast cancer: complete case analysis may introduce bias.
OBJECTIVE Many recent studies investigated the prognostic value of new biomarkers in breast cancer using data from cancer registries. Some of these studies were conducted using only patients for whom biomarker status was available (or tested). Using human epidermal growth factor receptor 2 (HER2) as an example, we determined whether testing for a recently introduced biomarker was associated wit...
متن کاملTree-based model for breast cancer prognostication.
PURPOSE To define prognostic groups for recurrence-free survival in breast cancer, assess relative effects of prognostic factors, and examine the influence of treatment variations on recurrence-free survival in patients with similar prognostic-factor profiles. PATIENTS AND METHODS We analyzed 1,055 patients diagnosed with stage I-III breast cancer between 1990 and 1996. Variables studied incl...
متن کاملA review on miRNAs as new biomarkers for colorectal cancer
Background & Objective: Since colorectal cancer does not often have phenotypic symptoms in the early stages, the study of biomarkers for the diagnosis and prognosis of the tumor is very important. MicroRNAs are one of the most important biomarkers which attract the attention of many researchers due to a variety of reasons, including their non-invasive nature; these molecules are a group of non-...
متن کاملBreast cancer imaging: a new role of Tc-99m sestamibi prone scintimammography for diagnosisof breast cancer
Mammography remians the procedure of choice in screening asymptomatic women for breast cancer. However, in patients with symptoms, other types of imaging play an important role in the detection of malignancies. The high cost and lack of availability of PET and MRI largely precludes the use in this patient population. TI-201 is nbt the imaging agent of choice because of its wash-out and redistri...
متن کاملVariation in Cell Signaling Protein Expression May Introduce Sampling Bias in Primary Epithelial Ovarian Cancer
Although the expression of cell signaling proteins is used as prognostic and predictive biomarker, variability of protein levels within tumors is not well studied. We assessed intratumoral heterogeneity of protein expression within primary ovarian cancer. Full-length proteins were extracted from 88 formalin-fixed and paraffin-embedded tissue samples of 13 primary high-grade serous ovarian carci...
