Objective:
The aim of the present study was to investigate the differences between therapeutic granulocyte-colony stimulating factor (G-CSF) cycles and prophylactic G-CSF cycles in patients receiving paclitaxel and carboplatin combination chemotherapy for ovarian cancer.
Material And Method:
Medical records of 15 women who received paclitaxel and carboplatin combination chemotherapy for ovarian cancer between January 2003 and December 2012 were analyzed retrospectively. All 15 patients completed 6 cycles of paclitaxel and carboplatin as the first-line chemotherapy. The complications were compared between therapeutic G-CSF cycles and prophylactic G-CSF cycles.
Results:
The number of chemotherapy cycles correlated with the ratio of prophylactic G-CSF cycles. It was considered that earlier prophylactic G-CSF injections were chosen due to a gradual decrease in WBC and neutrophil counts. The WBC and neutrophil counts were significantly higher in prophylactic G-CSF cycles than in therapeutic G-CSF cycles. However, there were no significant differences in the intervals of chemotherapy, delay of chemotherapy, and incidence of febrile neutropenia between the therapeutic G-CSF and prophylactic G-CSF cycles.
Conclusion:
Prophylactic G-CSF injections were not effective in preventing the incidence of febrile neutropenia in patients receiving paclitaxel and carboplatin combination chemotherapy for 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...
