Purpose
Timing of surgery during the menstrual cycle and its impact on survival in pre-menopausal women with operable breast cancer has been extensively researched and reinvestigated by Badwe et al in the randomized clinical trial of 'Primary Progesterone Therapy for Operable Breast Cancer' at Tata Memorial Hospital. The timing of surgery during the menstrual cycle and survival in breast cancer carries two distinct postulates. First, hormonal milieu in the host can modulate metastatic potential of breast cancer and second, events at the time of surgery can influence survival. In light of the interim results of the randomized trial of primary progesterone in women with operable breast cancer showing a significant difference in the node positive high risk tumors (SABCS,2009,Abstract no.72), it is logical to now test the role of primary progesterone in large operable and locally advanced breast cancer.
The active metabolite of vitamin D3, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), has been recognized for over 2 decades as a modulator of cell proliferation and differentiation (cytotoxic and anti-proliferative) in many cell types, including breast cancer. However, it is still unclear as to how 1,25(OH)2D3 and its synthetic analogues act within breast cancer cells to elicit the effects on cellular proliferation and differentiation.[6] Vitamin D3 has been shown to decrease tumor growth in animal models[7] and is now in Phase I clinical trials for human cancers. [8] Based on these observations it is proposed to test the role of vitamin D3 in the neoadjuvant setting as a negative growth regulator and potentiator of chemotherapy by evaluation of tumor response.
