The use of hyaluronic acid hydrogel as a tumour bed marker in breast-conserving therapy.

Purpose: To evaluate usefulness of hyaluronic acid (HA) hydrogel as a tumour bed marker in breast conserving therapy (BCT). To analyze inter- (Inter-OV) and intraobserver (Intra-OV) variability of contouring boost target volume (CTV) in external beam radiotherapy (EBRT).

Materials And Methods: Thirty-two patients in the HA group and 30 patients in the control group with an early stage breast cancer were included in the study.

Analysis of the involvement of cytokines in allergy and breast cancer association.

Aim Of The Study: The existence of a correlation between allergy disorders and cancer diseases has been confirmed by several epidemiological studies. Although the molecular mechanism involved in this phenomenon remains unknown, there are data indicating that certain cytokines, engaged in allergic processes, have antineoplastic activities. The aim of the present study was to explore the association between advanced breast cancer and allergic state on the molecular level.
