Intrathecal (IT) Herceptin (Trastuzumab) for brain mets (Leptomeningeal Metastases)

MRI of 2 weeks ago came out to be not as good as we expected. The 6 tumors that were present before stayed the same size, however there are some new small spots around the brain and so most probably this dosage of 100mg IT herceptin is not working to clear all. However doctors said that they are not certain that this means progression, it could be that this new spots are herceptin marks on the cells that were present. Now the dosage has been increased to 150mg IT herceptin together with 50mg steroid per week. My wife can tolerate this without any sde effects at all. Quality of life is still very good. We are also starting lapatinib as from next week, and then MRI is another 6 weeks or so, to check if the tumors start shrinking.
