Awareness of cancer therapy-induced toxicities is important for all clinicians treating patients with cancer. Cancer therapy has evolved to include classic cytotoxic agents in addition to newer options such as targeted agents and catheter-directed chemoembolisation. Several adverse affects can result from the wide array of treatments including effects on the liver, pancreas, and biliary system that can be visualised on imaging. These complications include sinusoidal obstruction syndrome, fatty liver, pseudocirrhosis, acute hepatitis, pancreatitis, pancreatic atrophy, cholecystitis, biliary sclerosis, and biliary stasis. Many of these toxicities are manageable and reversible with supportive therapies and/or cessation of cancer therapy. The objective of this review is to discuss the imaging findings associated with cancer therapy-induced toxicity of the liver, biliary system, and pancreas.Teaching Points• Cancer therapy can have adverse effects on the hepatobiliary system and pancreas.• Cancer therapy-induced toxicities can be visualised on imaging.• Knowledge of imaging changes associated with cancer therapy complications can improve treatment.
Nephrotoxicity is a common adverse effect of many chemotherapeutic agents. The agents most commonly associated with chemotherapy-associated nephrotoxicity are methotrexate, semustine, streptozocin, mithramycin, and cisplatin. Certain chemotherapeutic agents have adverse effects on the kidneys and urothelium that can be visualized radiographically, including cystic change, interstitial nephritis, papillary necrosis, urothelial changes, haemorrhagic cystitis, acute tubular necrosis, and infarction. This review focuses on imaging features identifying complications of chemotherapy in the kidneys and collecting system and provides didactic cases to alert referring clinicians.Teaching Points• Nephrotoxicity is a common adverse effect of many chemotherapeutic agents.• Chemotherapies have adverse renal and urothelial effects that can be visualized radiographically.• Crizotinib use can result in the development of complex renal cysts.
Background/Aim: 18 kDa Translocator protein (TSPO) is a mitochondrial protein up-regulated in colorectal carcinoma (CRC). Our purpose was to develop a TSPOtargeted doxorubicin prodrug (Dox-TSPO) which can be loaded onto drug-eluting beads for transarterial chemoembolization. Furthermore, we evaluated its loading and release kinetics and effects on cell viability. Materials and Methods: N-Fmoc-DOX-14-O-hemiglutarate was coupled with a TSPO ligand, 6-TSPOmbb732, using classical N,N,N',N'-tetramethyl-O-(1Hbenzotriazol-1-yl)uranium hexafluorophosphate coupling to produce Dox-TSPO. Loading and elution studies were performed using DC beads™. Cell viability studies were performed using CellTiter-Glo ® Luminescent Cell Viability Assay. Results: Dox-TSPO was successfully synthesized and readily loaded onto and eluted from DC beads™, albeit at a slower rate than free doxorubicin. CRC cell lines expressing TSPO were 2-to 4-fold more sensitive to Dox-TSPO compared to free doxorubicin at 72 h. Conclusion: Dox-TSPO is a promising candidate for targeted and directed cancer treatment of CRC liver metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
