Abstract
Cold atmospheric plasma (CAP) may have applications in treating various types of malignant tumors. This study assessed the anticancer effects of CAP using melanoma and colon cancer cell lines. CAP treatment significantly reduced the in vitro viability of melanoma and colon cancer cell lines and had a negligible effect on the viability of normal human melanocytes. Additionally, CAP and epidermal growth factor receptor (EGFR) inhibitor had an additive anticancer effect in a CAP-resistant melanoma cell line. Reactive oxygen and nitrogen species known to be generated by CAP enhanced the anticancer effects of CAP and EGFR inhibitors. The in vivo anticancer activities of CAP were evaluated by testing its effects against syngeneic tumors induced in mice by melanoma and colon cancer cells. CAP treatment reduced tumor volume and weight in both cancer models, with the extent of tumor reduction dependent on the duration and number of CAP treatments. Histologic examination also revealed the tumoricidal effects of CAP in both tumor models. In conclusion, CAP inhibits the growth of mouse melanoma and colon cancer cell lines in vitro and shows tumoricidal effects against mouse models of melanoma and colon cancer in vivo.

Abstract
The time interval between the diagnosis of tumor in a patient and the initiation of treatment plays a key role in determining the survival rates. Consequently, theranostics, which is a combination of diagnosis and treatment, can be expected to improve survival rates. Early detection and immediate treatment initiation are particularly important in the management of melanoma, where survival rates decrease considerably after metastasis. The present work reports for the first time the application of fluorescein isothiocyanate (FITC)-tagged epidermal growth factor receptor (EGFR)-functionalized ceria nanoparticles, which exhibit intrinsic reactive oxygen species (ROS)-mediated anticancer effects, for the EGFR-targeted diagnosis and treatment of melanoma. The theranostic activity was demonstrated using two-dimensional (2D) and three-dimensional (3D) models of parental and metastatic melanoma. Confocal imaging studies confirm the diagnostic activity of the system. The therapeutic efficiency was evaluated using cell viability studies and ROS measurements. The ROS elevation levels are compared across the 2D and 3D models. Significant enhancement in the generation of cellular ROS and absence in mitochondrial ROS are observed in the 2D models. In contrast, significant elevations in both ROS types are observed for the 3D models, which are significantly higher for the metastatic spheroids than the parental spheroids, thus indicating the suitability of this nanoformulation for the treatment of metastatic melanoma.

Abstract
The presence of ulceration in melanoma is associated with poor clinical outcomes and is the third most powerful predictor of survival in the AJCC Melanoma Staging System after tumor thickness and mitotic activity. The aggressive biological behavior associated with ulceration has been hypothesized to be the result of an intrinsic biological attribute that favors dissemination and presents locally with the loss of epidermal integrity. Among the features of ulcerated melanoma, many show promise as potential prognostic tools, markers of differential immunogenicity and indicators of oncogenic drivers of invasion and metastasis. The incidence of ulcerated melanoma is greater in males, increases with age and with systemic inflammatory risk factors (diabetes, smoking, low vitamin D, elevated body mass index). Patients with ulcerated primary tumors seem to exclusively benefit from adjuvant interferon (IFN) therapy, which is likely the consequence of an altered tumor microenvironment. When ulceration is present, there is a higher density of macrophages and dendritic cells and enhanced expression of pro-inflammatory cytokines, such as IL-6. There is also an increased expression of proteins involved in tumor antigen presentation in ulcerated melanomas. Histologically, vascular density, vasculogenic mimicry and angiotropism are all significantly correlated with ulceration in melanoma. The presence of ulceration is associated with reduced protein expression of E-cadherin and PTEN and elevated levels of N-cadherin and the matrix metalloproteinases. Differential microRNA expression also holds promise as a potential prognostic biomarker of malignancy and disease spread within the setting of ulceration. However, the molecular and cellular differences associated with the ulcerated state are complex and further study will aid in determining how these differences can be harnessed to improve care for patients with melanoma.
