With this treatment we were able to silence 92% TTR expression by the liver, avoiding TTR circulation in plasma and burden in tissues, as previously described [ 31].
It is therefore clear that the best and most reliable marker of fluid responsiveness is a PAC-derived parameter; moreover, despite its relatively low specificity and sensitivity, careful monitoring of PCWP during fluid administration may help in avoiding pulmonary circulation overload.
To form a metastatic focus, a tumor cell or group of cells is required to leave the primary tumor, invade local tissues and basement membranes, enter the circulation, avoid host immunological responses, attach to a distant vascular bed, extravasate into the interstitium of the target organ, and colonize to form a second tumor [ 23].
