Systems, methods and devices for in vivo monitoring of a localized response via a radiolabeled analyte in a subject
First Claim
1. A method for determining whether to administer a therapeutic amount of a chemotherapeutic drug for tumor treatment by determining an in vivo localized uptake response in solid tissue in a patient, comprising the steps of:
- positioning at least one sensor in vivo in solid tissue in a region of interest in the body of the patient;
administering a test dose of a C-14 radiolabeled chemotherapeutic drug to the patient;
detecting a signal from the at least one sensor corresponding to the radiation in the region of interest in the patient based on the administering step;
monitoring the signal over time to determine a localized uptake response in the solid tissue of the patient based on the administered test dose; and
determining whether to administer a therapeutic amount of a non-radiolabled version of the chemotherapeutic drug based on the determined localized uptake response to the test dose.

Abstract
Methods, systems, devices and computer program products monitor in vivo detected radiation in a target localized site within a subject, over a selected time period, to do one or more of: (a) quantify a radiation dose received at a local site; (b) assess bioreceptiveness to a particular treatment time or type; (c) evaluate the pharmacokinetics of a radiolabeled analyte corresponding to a non-radiolabeled analyte; (d) monitor or evaluate metabolic activity; or (e) evaluate a tumor prior to or after a therapeutic treatment.

39. A method for predicting, on a patient-specific basis, a likelihood of response to a known chemotherapeutic agent in a tumor site of a respective patient, comprising:
-
chronically positioning at least one sensor in vivo in solid tissue proximate a tumor site in a patient'"'"'s body;
administering a test dose of a C-14 radiolabeled chemotherapeutic agent;
detecting in vivo from the at least one sensor a signal over time corresponding to radiation proximate the tumor site in response to the administering step;
relaying the detected radiation signal to a location external of the patient'"'"'s body;
determining a patient-specific in vivo uptake response of the C-14 radiolabeled test dose in solid tissue proximate the tumor site based on the relayed radiation signal; and
determining whether to administer a therapeutic amount of a non-radiolabeled version of the chemotherapeutic agent based on the determined uptake response. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
