Hi, I've been reading Cancer Grace for some time, but this is my first post. I would be grateful for any thoughts about this (my oncologist is away at the moment and any interpretations or comparisons much appreciated)!
(My question first; my history below)
Question: I have just had a CT scan which shows that my main lung cancer tumor has shrunk following the first two sessions of chemotherapy (from 2.5 x 2.4 cm to 2.1 x 1.4cm). However, bone metastases, particularly in lumbar region, seem to have progressed further. What does this mixed result likely mean? Would you say the chemotherapy is working or not really?
History: diagnosed with metastatic lung cancer in early October 2012; adenocarcinoma, KRAS mutation; 38-yr old female, never-smoker; treated with paliative radiation to cervical vertebrae where there was pain, followed by chemotherapy (carboplatin and permetrexed) and I have now completed 2 of 4-6 planned sessions of chemotherapy.
