I had my CT scan this morning and this afternoon had a phone call to attend the hospital. The most serious finding was that I have had a large volume pulmonary embolus straddling the two pulmonary arteries. Although there is still blood flow around the embolus, it does explain why I have been breathless for the past few days and my general fatigue. Looking at it shows that there has been a genuine emergency and justifies my going back on full dose Clexane, which I have already started this evening.
The rest of the scan shows no liver metastases and no change in the size of the mass where the stricture is, but there is a significant thickening of the omentum, which will account for the bloating and discomfort that I am feeling. I think it is probably time that I restarted my treatment and it looks as though the most likely option id a clinical trial comparing cetuximab and an EGRF TKI.
