Abstract

Lymph node status is one of the decisive prognostic factors in breast cancer. Chemotherapy targeting regional lymphatic tissues has emerged as a promising therapy for the treatment of malignancies with a high tendency to disseminate lymphatically. The present study determined the drug concentrations in axillary lymph nodes after lymphatic chemotherapy (LC) in patients with breast cancer and compared the results with those receiving intravenous chemotherapy (VC) to investigate whether LC could improve the accumulation of anticancer drug in regional lymph nodes. Sixty patients with breast carcinoma confirmed by preoperative puncture-biopsy were divided into two groups at random. The LC group (n = 30) received a subcutaneous injection of 4 ml of carboplatin-activated carbon suspension, containing 20 mg of carboplatin, adjacent to the primary tumour. The VC group (n = 30) received an intravenous administration of an equal dose of aqueous carboplatin. At 1, 12, 24, 36 and 48 hours after administration, modified radical mammectomies were performed on 12 patients at each time point, with 6 from each group. Axillary lymph nodes were removed for pathological examination. The platinum concentrations in nodes were determined by Zeeman ato...Continue Reading

Breast Invasive Carcinoma

Invasive breast cancers indicate a spread into breast tissues and lymph nodes. Here are the latest discoveries pertaining to breast invasive carcinomas.

Breast Cancer: Chemo-Resistance

Some cancers are difficult to treat and aggressive including the "triple-negative" breast cancer. This type of cancer is chemoresistant even before chemotherapy begins. Here are the latest discoveries chemo-resistance in breast cancer.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Cancer Cell Invasion: Nanomedicine

Nanomedicine is a promising alternative for cancer detection and therapy that utilizes nanoparticles, such as liposomes. Nanoparticles can potentially target cancer cell invasion and metastasis. Discover the latest research on Cancer Cell Invasion: Nanomedicine here.
