Effect of progesterone combined with chemotherapy on epithelial ovarian cancer
1Department of Gynecology, Obstetrics and Gynecology Hospital, Fudan University, Shanghai 200011, China.
Objective:
To identify an effective auxiliary therapy for epithelial ovarian cancer.
Methods:
Progesterone acetate given at 250 mg intramuscularly twice a week for 1 month followed by increased administration to 500 mg intramuscularly every two weeks for 3 years was used in combination with platinum based chemotherapy to treat patients with epithelial ovarian cancer as a first-line therapy. Prognoses of the patients receiving progesterone combined with chemotherapy (progesterone group) and those receiving chemotherapy only (control group) were compared.
Results:
Three-year recurrence and survival conditions of the progesterone and control groups were as follows. Stage Ia: no patient relapsed or died in either group. Stage Ib-Ic: three-year recurrence rates were 14.2% and 37.5%, respectively (P = 0.2845); three-year survival rates were 92.3% and 87.5% (P = 0.7221). Stage II: 1 patient relapsed and died among the 3 patients in the progesterone group; among the 4 patients in the control group, 1 patient relapsed, none died. Stage III: three-year recurrence rates were 30.8% and 64.3%, respectively (P = 0.1170); three-year survival rates were 85.7% and 42.9%, respectively (P = 0.005). Stage IV: 4 patients relapsed and 1 patient died among the 7 patients in the progesterone group; both the patients in the control group relapsed and died.
Conclusions:
The results indicated that progesterone combined with platinum based chemotherapy as a first-line therapy may improve the prognosis of advanced epithelial ovarian cancer, but would not change the prognosis of early stage epithelial ovarian cancer.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
01:30Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
