Hello all,

My father is receiving cisplatin and radiation as well. From reading through
this forum, seems like people have received cisplatin at different intervals, some every 21 days, my father is receiving it once a week and at first they were going to give it to him 3 times a week. Does anyone know why there is such a discrepancy in how often it is given? I understand it probably has to do with each individual case, but if anyone knows if one interval is more effective then the other, I would really appreciate the help. Also, I was reading a few studies done on the effectiveness of radiation and cisplatin and one stated that it is more effective if cisplatin is administered 3 hours after radiation is given rather then before. I was not aware that it made a difference if cisplatin is given directly before or after radiation. I could not find any other studies on the matter and any info would help.

Thank you,

Swati
