Association of Hepatitis C Virus With Breast Cancer

Summary

Hepatitis C viral infection is a major health problem in Egypt. The management of breast cancer patients is often complicated by the presence of associated HCV infection. This study aims at investigating the epidemiological association of the two conditions. It will also investigate the possible correlation with treatment outcome.

Description

Breast cancer is the most common cancer in adult Egyptian females. The world`s highest prevalence of hepatitis C virus is found in Egypt. Several investigators examined the epidemiological association of HCV with breast cancer. Published literature reports conflicting results regarding the HCV association with breast cancer incidence. Population-based studies from HCV-endemic area demonstrated increased breast cancer incidence in HCV-positive women younger than 50 years. On the other hand, population studies from HCV-low prevalence regions failed to detect an association of the virus with breast cancer.

HCV seropositive patients constitute a large sector of oncology patients treated in Egyptian practice. HCV infection with or without clinically-significant liver disease impose several therapeutic, social and logistic problems. Recently, investigators from Mansoura University reported their findings among breast cancerpatients. According to these data, HCV-positive breast cancer patients had several markers of disease aggression such as large tumor size, high tumor grade and nodal infiltration. Moreover, HCV-NS4 (non-structural protein-4) blood levels positively correlated with the level of the known breast cancer marker CA15-3.

In the current study, the investigators will investigate the incidence of HCV seropositivity in breast cancer patients and an age-matched control group. The study also examines the association of HCV status on the patients' baseline characteristics such as tumor stage and grade and with patients` treatment plan and treatment outcome.

Specifically, the aims of the study are the following:

1. To test if HCV seropositivity is associated with breast cancer diagnosis in Egyptian population.

2. To test if HCV-positive patients harbour more aggressive breast tumors.

3. To test if HCV-positivity affects management decision in breast cancer patients.

4. To test if HCV-positive patients suffer more frequent adverse effects to breast cancer treatment.

5. To compare disease-free survival of HCV seropositive breast cancer patients vs. seronegative patients.

Medical and Biotech [MESH] Definitions

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
