Description

Lung cancer mortality continues to be the leading cause of death among men and women, despite a sharp decline in mortality rates for melanoma and lung cancer that can be attributed to advances in treatment such as immune checkpoint inhibitors, centered drug therapy, and a decrease in cancer risk factors. Chemotherapeutic tablets continue to be the gold standard treatment because they employ a "one-size-fits-all" approach that lacks precision and results in significant variations in patient response to therapy [2]. This is the case despite advancements in novel, targeted interventions and therapies. Through a variety of methods, including 3-dimensional (3D) scaffold, bioprinting, spheroid, and hydrogel culturing 3D tumor models, which have been proven to have advantages over bidimensional (2D) cultures in evaluating the efficacy of chemotherapeutics due to their heterogeneity and simulating the tumor microenvironment, recent research has attempted to better learn about chemotherapy dealers. 3D tissue models have been used to determine toxicity and drug resistance to chemotherapeutic dealers concurrently within distinct cells, in addition to evaluating the drug's efficacy and pharmacodynamics [3].

In the last ten years, a number of research papers have been published on the use of cancer cell lines to create three-dimensional in vitro tumor models. These models hold the promise of providing patients with individualized treatment. The purpose of this commentary is to compile and discuss the most recent findings regarding the application of biomaterials with patient-derived cancer cells for near-universal use in clinics. The Role of Patient-Derived Cancer Cells and Biomaterials Although 3D bioprinting has progressed significantly, many obstacles remain in the way of creating tumor models with physiological relevance and reliable data for personalized treatment.The challenges that need to be addressed include the capacity to replicate tumor microenvironments and establish vasculature for excellent oxygen and nutrient distribution to specific areas within the 3D tradition. 3D tumor models are still more expensive and time-consuming than 2D models, despite their benefits and increased use and acceptance. As a result, traditional two-dimensional models are still extensively utilized by pharmaceutical companies for drug development, despite the fact that they do not precisely represent the tumor microenvironment, limiting their application for anticancer drug screening [4].

In contrast to 3D cultures, 2D phone cultures have developed little drug resistance, which has increased drug discovery failure rates. 3D tissue models better replicate the physiological aspects of tumor tissue, such as the delivery of oxygen and nutrients, gene expression, and cell proliferation. The tumor microenvironment is heavily influenced by immune cells, inflammatory mediators, and vasculature, all of which add complexity. As a result, 3D tumor models based on patient-derived cancer tissue will more closely mimic the in vivo microenvironment and have a higher predictive value than conventional models [5].

Conclusion

Biomaterials and patient-derived cells for the creation of three-dimensional tumors are relatively recent and uncommon developments. It is essential to acknowledge the current limitations of these innovative in vitro models, despite the fact that they hold great promise due to their more accurate cellular environments that are similar to those of the patient. These models face a number of challenges, including having to replicate the heterogeneous nature of cancer cells and mimic their molecular biology, physiology, and genetic makeup. Finding a method to create a network of vasculatures in tumors is a major obstacle.

3D tumor growth would be difficult, if not impossible, without these capillary networks. However, research has shown that stem cells can be transformed into endothelial cells, thereby promoting angiogenesis, if these bioprinted models are able to take into account cellular and molecular factors. In addition, a number of studies have demonstrated that a variety of cancers interact with the stromal cells and environmental factors that surround them to accelerate their growth, making it difficult to recreate these complex microenvironments. This presents a challenge because it is not as straightforward as simply combining these factors and cells and expecting the same system to exist. These three-dimensional models were made with cell viability in mind because the shear forces of bioprinting frequently cause damage to cells, rendering them useless. Significant progress has been made possible by modern technology; However, the process of creating these individualized and precise 3D tumor microenvironments is time-consuming, costly, and very limited.
