Systems, kits and methods for preparing an injection system and/or treating target lesions with a selective internal radiation therapy which includes a double-barrel syringe loaded with a two-component tissue glue and radioisotope loaded microspheres. The microspheres are loaded into the syringe based on the size of the target location and are administered with a needle or dual-lumen catheter. Dosing regimens for treating breast cancer lesions or surgical beds up to 130 mm in diameter and hepatocellular carcinoma lesions up to 50 mm are included.

ANTI-TUMORAL COMPOUND AND RELATIVE PRODUCTION PROCESS
20230087252 · 2023-03-23 · ·

An anti-tumoral compound for the localized treatment of neoplastic pathologies of malignant kind that cannot be surgically removed or with a high risk of local recurrence, includes: a bicomponent injectable biologic glue; an antineoplastic substance; and an epinephrine-based solution. The compound may be used as an independent therapeutic treatment, as it allows to treat tumoral masses that are not surgically removable, or as a therapeutic treatment complementary to surgical removal or to known ablative techniques (laser, radiofrequency, microwaves, etc.) for a maximization of the efficiency of therapies reducing the risk of neoplastic relapses in the original surgical site. A process for the production of the antitumor compound is also described.

Radioactive cement

A target tissue can be treated with a radioisotope. Some methods for treating a target tissue with a radioisotope include determining a distance between a target tissue and a surface of a matrix material to be positioned adjacent the target tissue and, based on the determined distance, determining an activity to be mixed with the matrix material to obtain a desired activity concentration. Some methods further include mixing the radioisotope with the matrix material. In some embodiments, the matrix material comprises bone cement, and the target tissue is a tumor in a bone. The radioisotope may be a beta-emitting radioisotope mixed in the cement at a concentration to form a radioactive cement.
