Abstract

We retrospectively evaluated the prognostic significance of dual-time point (DTP) 18F-FDG positron emission tomography/computed tomography (PET/CT) parameters compared with clinicopathological findings in premenopausal women with invasive ductal breast carcinoma (IDC). Sixty-six premenopausal women (mean age: 42.7 ± 5.6, range: 29.5-51.8 years) who had pathologically confirmed IDC were enrolled. The maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were measured and used to calculate percentage changes over the DTP time interval. We analyzed the prognostic significance of DTP PET/CT parameters, clinicopathological factors of pathologic tumor diameter (pTD), axillary lymph node status (ANS), nuclear grade, histologic grade, and immunohistochemistry findings using univariate and multivariate analyses. Disease recurrence was observed in 22 patients. In univariate analysis, SUVmax > 7.39, MTV > 4.28, TLG > 52.38, %ΔSUVmax > 20.44, %ΔTLG > -13.86, pTD > 2.8 cm, positive ANS, estrogen receptor (ER) negativity, and triple negativity were associated with worse prognosis than those of opposite groups in recurrence-free survival (all p < 0.05). %ΔSUVmax (>20.44, p = 0.0042), TLG (...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Carcinoma, Ductal

Ductal carcinoma is a malignant neoplasm involving the ductal systems of any of a number of organs, such as the mammary glands, pancreas, prostate or lacrimal gland. Discover the latest research on ductal carcinoma here.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.

Breast Invasive Carcinoma (Keystone)
