Hugs,
MarionMarion, G and I much appreciate your many posts like this one. Having recently found ourselves in the CC realm your info is helping us up the steep learning curve. Learned the hard way that Norco caused constipation. Lorazepam for itchiness causes unacceptable lethargy; had to cut the recommended dosage from 1 to 2 mg every 6 hours down to 1/4 mg every 8 hours. We aren’t doctors but we do discover what works for her, which no doubt is different from others.
Marion,
Thank for for that info. I’ve seen these terms bandied about, but other than thinking about them in the most general terms…I did not know what they meant…esp partial response and stable disease.

This subject comes up often. Tumor is considered stable and yet is determined active in a follow-up scan. Stable tumor – what does it mean?
Imaging Response Criteria
•CR (complete response) = disappearance of all target lesions
•PR (partial response) = 30% decrease in the sum of the longest diameter of target lesions
•PD (progressive disease) = 20% increase in the sum of the longest diameter of target lesions
•SD (stable disease) = small changes that do not meet above criteriahttp://imaging.cancer.gov/clinicaltrials/imaging
