ABSTRACT

The effectiveness of standard cancer treatment methodsincluding chemotherapy and radiotherapy and immunotherapybecomes limited because of the hostile and adaptivecharacteristics of the Tumor Microenvironment (TME) ratherthan natural cancer cell resistance. The TME functions as anobstacle to treatment because it contains abnormal bloodvessels and extreme low oxygen levels and acidic conditionsand thickened and linked extracellular matrix (ECM). Theresearch report describes how nano-oncology has evolved fromusing drug delivery systems that passively release medicationsto active TME modification platforms. The research presents adetailed study of intelligent nanospheres which transform theTME from its current state of drug resistance andimmunosuppression into an environment that supports drugpenetration and immune system activation. The nanocarriersachieve their purpose through three main actions which include generating oxygen within tumors to fight hypoxia and using biomimetic approaches totransform TAMs and enzymatic methods to break down stromal barriers. The advancednanocarriers present a new method to fight drug resistance through their ability to generateoxygen in tumors and transform TAMs and break down stromal barriers. The researchinvestigates pharmaceutical system development through microfluidic models and advanced characterization methods to verify their suitability for medical use. The report assesses the clinical development of radio-enhancers (NBTXR3) and photothermal agents (AuroLase) and theranostic radiosensitizers (AGuIX) through essential clinical tests to demonstrate their ability to transform current treatment standards. The document presents a future-oriented view of Artificial Intelligence (AI) assisted design and hybrid systems to establish that oncology will succeed through environmental transformation rather than cancer cell elimination.
