The present invention is directed to compositions and methods targeting cells in a subject harboring conditions or at risk for conditions that would benefit from gas-based diagnostic and therapy. The present invention relates to the use of fluorochemical compositions and methods of delivery that result in retention of the fluorochemical composition and any bioactive agent, including gaseous substances, delivered in combination with the fluorochemical composition.

Provided herein are methods for decreasing the toxicity of advanced ablative cancer therapies on neighboring organs. The methods herein provide spacing between single or multiple tumor cites and immediate healthy organs while maintaining or increasing patient quality of life. Such toxicity isolation can be performed by inserting a spacer around the one or more tumor cites, which can be performed concurrently with fiducial marker placement.

Conjugates are described herein where CCK2R targeting ligands are attached to an active moiety, such as therapeutic agent or an imaging agent, through a linker. The conjugates can be used in the detection, diagnosis, imaging and treatment of cancer.

Disclosed herein is a benzene ring-containing glucose derivative of formula (I):

##STR00001##

, where R.sub.1 is each independently

##STR00002##

and R.sub.2 is hydrogen. This application also provides a radioactive drug, including a complex formed by the benzene ring-containing glucose derivative and a radionuclide. Use of the benzene ring-containing glucose derivative in the tumor treatment and diagnosis is further provided.

A radioactive thermogel suspension, including a thermogel and a plurality of insoluble radioactive isotope phosphate particles, such as yttrium phosphate, suspended in the thermogel. The thermogel is PLGA-g-PEG. The thermogel contains less than 65 ppm stannous octanoate. The plurality of radioactive yttrium phosphate particles are between 0.03 .Math.m and 10 .Math.m in diameter. The plurality of radioactive yttrium phosphate particles are generally spherical. The YPO.sub.4 particle concentration is in the range of 3 mg/ml to 100 mg/ml.
