Abstract :

Current imaging and exploration of the surgical field using inspection and palpation provides the surgeon with limited information for clinical decision making. Using colorectal adenocarcinoma as a model, we developed a â??systemâ? that incorporates currently available technologies to increase the precision of tumor imaging before and during surgery. The system has three parts: 1) a tumorrelated marker, 2) a labeled molecular probe, and 3) instrumentation for imaging and/or detection of the labeled tumor. The glycoprotein TAG-72 is expressed in more than 80% of adenocarcinomas of the: colon and rectum, pancreas, lung, prostate, endometrium, and ovary. We utilized three different generations of 125I-labeled murine IgG antibodies to TAG-72. Our earlier studies used a hand-held gamma probe for the detection and excision of TAG-72 positive tissues. Follow-up studies clearly demonstrated that, independent of the pathologic stage, patient survival was significantly better if all of the TAG-positive tissue was removed. In the last 25 tears the â??systemâ? has evolved to the use of low energy labeled, small, molecular probes that allow for combined intraoperative imaging and detection. We bioengineered humanized, single chain, fragments and its â??mersâ?, to TAG-72 that minimize murine antibodies associated problems. 123I-labeling of these small molecules provides an optimal signal-to-noise ratio. The â??Systemâ? now allows for preoperative SPECT/CT imaging to determine actual disease extent prior to surgery and for using a portable gamma camera for realtime intraoperative imaging while retaining hand-held-gamma probe detection of TAG-72 positive tissue. Proof-of-concept studies clearly demonstrate that the surgeon can â??get it allâ?.
