SEMA4C as a Relapse Biomarker in Breast Cancer

October 6, 2021 updated by: Qinglei Gao, Tongji Hospital
Breast cancer remains the most common cancer in women worldwide. Semaphorin4C (SEMA4C) has previously been identified as a highly expressed protein by breast cancer-associated lymphatic endothelial cells (LECs). The objective of this study is to investigate SEMA4C's potential role as an early relapse biomarker in breast cancer.

Study Overview

Detailed Description

Breast cancer remains the most common cancer in women worldwide, with approximately 1.68 million new cases, and 0.52 million deaths, annually. Meanwhile the incidence of breast cancer continues to increase. Although regular clinical examination, mammography, ultrasonography, and magnetic resonance imaging can detect some recurrence patients, the lack of robust biomarkers for monitoring of anti-tumor therapies and detection of recurrence reduce the treatment effectiveness of current strategies for breast cancer.

Semaphorin4C (SEMA4C) has been previously identified as a highly expressed protein by breast cancer-associated lymphatic endothelial cells (LECs) using in situ laser capture microdissection of lymphatic vessels, followed by cDNA microarray analysis. Moreover, membrane-bound SEMA4C is cleaved by matrix metalloproteinase (MMPs) to release a soluble form of this protein. The study is undertaken to explore SEMA4C's potential role as an early relapse biomarker in breast cancer.

Study Population

Participants including patients with breast cancer. All cases were confirmed histopathologically according to the WHO Classification of Tumors.

Description

Inclusion Criteria:

  • Have histologically confirmed new diagnosis of breast cancer according to biopsy or surgery

Exclusion Criteria:

  • Patients who are not mentally capable of giving written informed consent
  • Serum samples doesn't qualified
  • Patients who refuse follow-up on their conditions
  • Patients with prior cancer history
  • Patients with a diagnosis of other severe acute or chronic medical may increase the risk associated with study participation or may interfere with the interpretation of the study results and, in the judgement of the Investigator, would make the patient inappropriate for enrollment in this study

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
SEMA4C high value follow-up group
Postoperative SEMA4C value is higher than 5.00 ng/ml.
Serum samples will be collected every 3 months for the first year after surgery and then every 6 months to first progression defined as death or recurrence of the breast cancer or until 5 years since last patient in, whichever occurs first. Imaging examination and biopsy or surgery if necessary are recommended for patients with elevated SEMA4C. Serum SEMA4C levels will be tested in single center in order to decrease bias and be measured using a double antibody sandwich ELISA method using in-house SEMA4C detection kits.
SEMA4C low value follow-up group
Postoperative SEMA4C value is lower than 5.00 ng/ml.
Serum samples will be collected every 3 months for the first year after surgery and then every 6 months to first progression defined as death or recurrence of the breast cancer or until 5 years since last patient in, whichever occurs first. Imaging examination and biopsy or surgery if necessary are recommended for patients with elevated SEMA4C. Serum SEMA4C levels will be tested in single center in order to decrease bias and be measured using a double antibody sandwich ELISA method using in-house SEMA4C detection kits.
