ABSTRACT

Objective To evaluate the use of LHRH A for treating prostatic cancer with the occurrence of metastasis or recurrence after castration. Methods LHRH A has been instituted to 9 cases of pathologically verified prostatic cancer with the occurrence of metastasis or recurrence after castration.The therapeutic results were studied. Results Ideal improvement was noted in 4 with all the parameters turned normal.These 4 patients have survived well for 7,3,2 and 1 year respectively.Marked improvement occurred in 2 with part of the parameters turned normal or markedly improved shortly after the treatment.The condition of 1 patient became stable with drop of blood PSA and shrinkage of the prostatic mass.In 3 patients,the metastatic lesion became stable.with the use of LHRH A,the penis became markedly atrophic. Conclusions LHRH A is markedly effective in most cases of prostatic cancer with the occurrence of metastasis or recurrence after castration.The therapeutic efficacy depends on the sensitivity of the prostate cancer cells to the drug.Drug resistance may issue as time goes by.
