Chemotherapy regimen for breast cancer

Almost all anticancer drugs play a role in cell division. Because normal cells don't divide as frequently as cancer cells, they are not susceptible to the fatal effects of anticancer drugs. In addition, different anticancer drugs can be applied to cancer cells at different growth stages, so as to kill cancer cells to the maximum extent and help improve the curative effect. The commonly used chemotherapy schemes in clinic are: ① improved CMF scheme; ②AF scheme; ③ Exchange plan.

CMF plan;

CTX- cyclophosphamide; MTX- methotrexate 15-Fu-5- fluorouracil.

CTX600 mg, intravenous injection.

MTX 1o ~ 15mg, intravenous injection.

5-FU500 mg, intravenous drip.

Among the above three drugs, MTX was injected first, and CTX and 5-FU were injected after 6 hours to achieve drug synergy. Give/kloc-0 once every 7 ~ 10 days, 2 ~ 3 times each time, and stop using for 2 ~ 3 weeks. For 1 ~ 2 years.

(2)AF scheme:

ADM- adriamycin; 5- fluorouracil.

ADM 30 ~ 40 mg, intravenous injection; 500mg 5-Fu, intravenous drip, every 3 weeks 1 time.

(3) Exchange plan:

ADM- adriamycin; CTX cyclic amine phosphate.

ADM 30 ~ 40mg, intravenous injection; CTX600 mg, intravenous injection, 65438 0 times every 3 weeks.

AF scheme and AC scheme: rest every 3 ~ 5 months 1 ~ 2 months.

Because chemotherapy drugs have the same killing effect on normal cells of the body, the effective dose of chemotherapy for breast cancer is quite close to that of poisoning. At the same time, because chemotherapy itself can inhibit the immune function of the host, when the immunosuppression effect of administration exceeds the anti-tumor effect, it can sometimes have an irreversible effect on the main organs. Damage, hoping to attract attention.
