Chemotherapy treatments produce strong side effects like hair and weight loss, fatigue, nausea and vomiting. Researchers found a new agent that accumulates in the tumour tissue and is activated there by ultrasound waves does not have this problem.<\/p>\n\n\n\n

Platinum complexes are among the most commonly used drugs against cancer. They are successful, but with many severe side effects. An international research team led by Dr. Johannes Karges from Ruhr University Bochum, Germany, has now found a partial solution for that, the university writes in a press release<\/a>. <\/p>\n\n\n\n

The cell-damaging effect of this complex only unfolds where it is actually wanted. \u201cWhere previous studies relied on light activations that can only penetrate a few millimetres deep into the tissue, we have now developed a treatment method with ultrasound activation that penetrates several centimetres deep into the body,\u201d says Karges. This could make treatment with few side effects possible even for large and deep-seated tumours. <\/p>\n\n\n

Harmless in healthy tissue<\/strong><\/h2>\n\n\n\n

The platinum(II) complexes cisplatin, oxaliplatin and carboplatin are among the most commonly used cancer drugs. Their clinical success is offset by severe side effects, such as nausea, vomiting, kidney damage and bone marrow suppression. To overcome these limitations, major research efforts have been invested in the development of so-called platinum(IV) complex prodrugs over the past decades. \u201cThese prodrugs are stable and inactive, so they are completely harmless,\u201d explains Johannes Karges. \u201cIn healthy tissue, they are supposed to stay that way. In cancer tissue, however, they should be rapidly converted into the therapeutically active platinum(II) complexes.\u201d<\/p>\n\n\n\n

Energy is required for the reduction of the metal complex. Previous studies reported activation with ultraviolet, blue or red light. \u201cThe problem is that light can only penetrate less than a centimetre deep into the body and thus does not reach many tumours,\u201d explains Johannes Karges. To overcome this limitation, his team has for the first time combined platinum(IV) complex prodrugs with sonosensitizers that can be selectively activated with ultrasound irradiation.<\/p>\n\n\n

Nanoparticles accumulate in the tumour<\/h2>\n\n\n\n

To develop a therapeutically effective complex, the researchers encapsulated the platinum(IV) complex prodrugs and the sonosensitizers together in haemoglobin to form nanoparticles. \u201cWe were able to observe that the nanoparticles selectively accumulated in a mouse intestinal tumour after injection into the bloodstream, thus supporting targeted treatment,\u201d reports Johannes Karges. \u201cAfter irradiation with ultrasound, the platinum(IV) prodrug was activated at the tumour site, triggering the release of cisplatin, which is toxic to cells, and almost completely eradicating the tumour.\u201d<\/p>\n\n\n\n

Advantages of ultrasound<\/strong><\/h2>\n\n\n\n

These results could pave the way for the development of novel techniques and agents for the treatment of very large or deep-seated tumours. Ultrasound can penetrate more than an order of magnitude deeper into tissue than near-infrared light. In addition, ultrasound treatments are generally considered to be less invasive and easy to use. Another advantage is that hospitals are usually already equipped with the necessary equipment. \u201cOur work is still fundamental research,\u201d Johannes Karges emphasises. \u201cWhether and when treatments based on this can be offered in clinical practice is not yet foreseeable.\u201d<\/p>\n","protected":false},"author":2583,"featured_media":495222,"template":"views\/single-selected.blade.php","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[34665],"tags":[30764,25976,53279,54647],"location":[24456],"internal_archives":[],"class_list":["post-442639","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-health","tag-cancer-treatment","tag-chemotherapy","tag-ruhr-university-bochum","tag-ultrasound","location-germany"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2023\/02\/Hospital-Intravenous-Feeding.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/francesco-morelli\/","display_name":"Francesco Morelli"},"relative_dates":{"created":"Posted 3 years ago","modified":"Updated 3 years ago"},"absolute_dates":{"created":"Posted on April 7, 2023","modified":"Updated on April 7, 2023"},"absolute_dates_time":{"created":"Posted on April 7, 2023 8:00 am","modified":"Updated on April 7, 2023 8:00 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Health<\/a>"],"unlinked":["Health<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["cancer treatment<\/a>","chemotherapy<\/a>","Ruhr University Bochum<\/a>","ultrasound<\/a>"],"unlinked":["cancer treatment<\/span>","chemotherapy<\/span>","Ruhr University Bochum<\/span>","ultrasound<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_642eb6cf2e35f<\/a>"],"unlinked":["pll_642eb6cf2e35f<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Germany<\/a>"],"unlinked":["Germany<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/442639","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2583"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/495222"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=442639"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=442639"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=442639"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=442639"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=442639"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
