Squamous cell carcinoma of skin has become an important matter of discussion worldwide due to high number of deaths. Treatment of such cancer involves use of drugs (chemotherapy) along with surgery or radiation therapy. The combination chemotherapy is preferred over single treatment modality may be due to synergistic effect of targeting agent resulting in reduced drug dose, reduced cytotoxic effect and improved efficacy and survival rate. The objective of this work is to provide insight into the squamous cell carcinoma of skin; the various approaches and challenges adapted to surmount the cancer malignancies.
Research evidence shows that nanoparticle based therapeutic delivery to squamous cell carcinoma is equanimous to lead therapeutic approaches for intervention of cancer growth. Active chemotherapeutic approach is one of the leading therapies to such cancer cells due specific selectivity towards the EGFR-receptors over-expressed in tumor cells. Review of numerous research publications revealed innate toxicity of chemotherapeutic agents, and substantiated active receptor mediated drug targeting for therapeutic regime. These actively functionalized nanoparticles have been delivered to the targeted cells with higher selectivity, minimal toxicity and better retention in the cell.
Numerous approaches and strategies have been designed till date for successful delivery of drug to cancer cells. The techniques have shown tremendous improvement in getting normalcy of carcinomas but a few have been marketed so far.
Indeed, receptor based drug targeting approach through molecular signal transduction pathways involved in skin cancer development will provide insight into squamous carcinoma. Despite of these, other such challenges in drug delivery to squamous cell carcinoma need further clarification.
由于死亡人数众多,皮肤鳞状细胞癌已成为全球范围内重要的讨论话题。此类癌症的治疗包括使用药物(化疗)以及手术或放射治疗。联合化疗优于单一治疗方式,这可能是由于靶向药物的协同作用,从而降低了药物剂量、减少了细胞毒性作用并提高了疗效和生存率。本研究的目的是深入了解皮肤鳞状细胞癌;以及为克服癌症恶性肿瘤所采用的各种方法和挑战。
研究证据表明,基于纳米颗粒的治疗性递送对皮肤鳞状细胞癌而言等同于领先的癌症生长干预治疗方法。主动化疗方法是针对此类癌细胞的主要治疗方法之一,因为它对肿瘤细胞中过度表达的表皮生长因子受体(EGFR)具有特异性选择性。对众多研究出版物的综述揭示了化疗药物的固有毒性,并证实了主动受体介导的药物靶向治疗方案。这些具有活性功能化的纳米颗粒已以更高的选择性、最小的毒性和更好的细胞内保留率递送至靶细胞。
迄今为止,已经设计了许多方法和策略来成功地将药物递送至癌细胞。这些技术在使癌症恢复正常方面显示出了巨大的进步,但到目前为止只有少数已上市。
的确,通过参与皮肤癌发展的分子信号转导途径进行基于受体的药物靶向方法将为鳞状细胞癌提供深入了解。尽管如此,在向皮肤鳞状细胞癌递送药物方面的其他此类挑战仍需要进一步阐明。
