Maintenance Options for Brain Mets (Adeno. Lung Ca) - 1253071

Dear Dr. West,

My oncologist is suggesting to put me on maintenance therapy with Docetaxel+ Avastin which shall be changed to Alimta+ Avastin after 1 or 2 cycles of the former drug combination
.
I would greatly appreciate your opinion on following queries

1. If Avastin is relatively safe for patients like me( I suffer from seizures and my platelet count usually lies in 110,000 - 150,000 range).

2. Any suggestions on other potentially beneficial drugs or noble therapies which can be tried with or without Avastin and have some activity in brain mets and lung ca?

Looking forward to hear from you.

Thanks & Regards,
Rob

Hi Rob, I hope you are feeling alright. I'm not a doctor but more of a receptionist here on Grace. I will contact a doctor to comment on your queries. It may take a day to receive a reply.
I hope you do well moving forward and don't hesitate to ask followup questions.

I've just been looking for a blog/post I think was very recently released by Dr. West but I can't find it. It speaks to the idea that systemic therapy such as tarceva (if you're egfr positive) and alimta may have some activity in the brain for a section of the population.

But this is a thread that discusses the idea, http://cancergrace.org/lung/topic/any-way-to-control-brain-mets-after-f…

Perhaps someone can help find the post?

Presuming that your seizures are from brain mets, symptomatic brain metastases are considered a contraindication to Avastin. Also, I should mention that we really don't know how much incremental value bevacizumab adds to maintenance chemotherapy.

Janine had mentioned Tarceva (erlotinib), which can certainly have activity against brain metastases, but that is much more likely in someone with an activating EGFR mutation. I don't consider any systemic therapy to be so active against brain metastases that this should really factor into the decision-making process -- this isn't really well-studied enough to base decisions on this, nor is the suggestive evidence for any agent really compelling enough to lead me to make any clear suggestion. If anything, Alimta (pemetrexed) is probably the standard chemo agent most associated with responses in the brain, but I'm sorry to say that I really don't think there's enough good quality evidence to answer the question meaningfully.
