Prognostic significance of lymphatic vessel invasion diagnosed by D2-40 in Chinese invasive breast cancers.

Lymphatic vessel invasion (LVI) is promising in determining prognosis and treatment strategies, but the application of LVI as a histopathological criterion in breast cancer patients especially those of different subgroups is controversial. This research aims to evaluate the prognostic value of LVI assessed by D2-40 not only in patients with early invasive breast cancer but also in lymph node-negative, lymph node-positive, luminal A-like, luminal B-like, HER2-enriched, and triple-negative subgroups.The study cohort included 255 patients with a median follow-up of 101 months.

Primary or metastatic hepatic carcinoma? A breast cancer patient after adjuvant chemotherapy and radiotherapy postoperatively with intrahepatic cholangiocarcinoma and review of the literature.

Background: The liver is a common site of metastases, followed by the bone and lung in breast cancer. The symptoms of hepatic metastases are similar to intrahepatic cholangiocarcinoma (ICC). ICC is rare, with an overall incidence rate of 0.

[Flow cytometry-pathology combined study of breast cancer].

Objective: To study the relation between histopathologic grading and some of the cytogenetic and molecular biology characteristics of breast cancer.

Methods: On the basis of estrogen receptor (ER) expression, DNA content, S-phase fraction (SPF), bcl-2 and mutant p53 protein (mtp53) expression were examined by FCM in 121 breast cancer patients. In 66 patients with invasive ductal breast cancer, histopathologic grading was also examined.
