Cruse","doi":"10.1158/1538-7445.AM2021-308","DOIUrl":"https://doi.org/10.1158/1538-7445.AM2021-308","url":null,"abstract":"Skin cancer (SC) is the most common carcinoma affecting 3 million people annually in the United Sates and millions of people worldwide. It is classified as melanoma skin cancer (MSC) and non-melanoma skin cancer (NMSC). NMSC represents approximately 80% of NMSC and includes squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). MSC, however, has a higher mortality rate than SC because of its ability to metastasize. SC is a major health problem in the United States with significant morbidity and mortality in the Caucasian population. Treatment options for SC include cryotherapy, excisional surgery, Mohs surgery, curettage and electrodessication, radiation therapy, photodynamic therapy, immunotherapy, and chemotherapy. Treatments are chosen based on the type of skin cancer and the potential for side effects. Novel targeted therapies are being used with increased frequency for large tumors and for metastatic disease. The objective of this review is to highlight new chemotherapeutic agents that utilize silver nanoparticles in the management of SC. A scoping literature search on PubMed, Google Scholar, and Cancer Registry websites revealed that traditional chemotherapeutic drugs have little effect against SC after the cancer has metastasized. Following a discussion of SC biology, epidemiology, and treatment options, this review focuses on the mechanisms of advanced technologies that use silver nanoparticles in SC treatment regimens.

Prabhu","doi":"10.1158/1538-7445.AM2021-LB023","DOIUrl":"https://doi.org/10.1158/1538-7445.AM2021-LB023","url":null,"abstract":"Tumor Treating Fields (TTFields) have been clinically proven as safe, effective, and non-invasive approach for cancer treatment. Specifically, TTFields in conjunction with Gemcitabine/nab-Paclitaxel have shown promising results in Phase II pancreatic cancer (PC) PANOVA study. It is imperative to understand here that while TTFields are very safe, concurrent use of anticancer drugs will continue to elicit non-site-specific adverse effects resulting in overall low patient compliance. To overcome this drawback, we have developed an innovative strategy called ‘Tumor Treating Fields Triggered Targeting of Nanoparticles in Cancer (TTFields-TTONIC)9. For this, self-assembling cationic-anionic polymer nanoparticles (S-CAP NPs) encapsulating Gemcitabine as a model anticancer drug were developed. The hypothesis involves combination of NPs and TTFields wherein the developed NPs will be preferentially taken up by the tumor owing to leaky vasculature. Further, only under the applied TTFields, the NPs will be destabilized due to high charge density of cationic and anionic polymers leading to targeted release of encapsulated drug at the tumor site (reduction in non-site-specific side effects). For this, multiple batches of two types of S-CAP NPs [chitosan- bovine serum albumin (Chitosan-BSA) and polyethylenimine- bovine serum albumin (PEI-BSA)] were developed. The formulations were optimized using mathematical modelling and Design Expert® software to achieve low particle size and optimum encapsulation efficiency. Based on the results, 2 formulations from each type i.e., chitosan- BSA S-CAP NPs [Batch C4 - particle size: 210.54 ± 38.96 nm, PDI: 0.194, encapsulation efficiency: 61.26 ± 5.11%, zeta potential: (+) 7.38 ± 3.11; Batch C7 - particle size: 215.67 ± 32.55 nm, PDI: 0.201, encapsulation efficiency: 65.31 ± 5.84 %, zeta potential: (+) 3.22 ± 1.28] and PEI-BSA S-CAP NPs [Batch P5 - particle size: 198.29 ± 41.05 nm, PDI: 0.227, encapsulation efficiency: 58.83 ± 3.33%, zeta potential: (+) 8.17 ± 2.63; Batch P8 - particle size: 209.92 ± 31.33 nm, PDI: 0.196, encapsulation efficiency: 64.31 ± 5.13%, zeta potential: (+) 11.49 ± 2.99] were shortlisted that exhibited particle size ~ 200 nm and encapsulation efficiency in range of 55-65 %. All the formulations exhibited sustained drug release profile over a period of 60 h wherein chitosan- BSA S-CAP NPs showed slower drug release compared to PEI-BSA S-CAP NPs (P Citation Format: Preshita Prafulla Desai, Sunil Prabhu.
