Background: In oncology, major surgical interventions are often followed by an interim period of 3–6 months allowing the patient to recover, following which conventional radiotherapy and chemotherapy are initiated. Lack of therapeutic interventions in the interim period allows proliferation of the residual tumor cells. Thus, introducing a treatment modality in the interim period which inhibits tumor cells without exuberating the postsurgical morbidity is the need of the hour. The objective of the study is to fabricate biodegradable cross-linked scaffolds incorporated with an anticancer drug and optimization of scaffolds for drug release. Materials and Methods: Qualitative and quantitative characterization of the drug was done with the help of high-performance liquid chromatography (HPLC) and ultraviolet (UV) analysis. Three-dimensional (3D) discs of biodegradable scaffolds were prepared with anticancer drugs in aqueous solution in different concentrations along with crosslinkers. Discs were studied for their release kinetics with the help of HPLC. Results: HPLC analysis of the 3D-discs revealed negative results. There was no sign of cisplatin absorbance after the scaffold immersion in the solution. The results were attributed to the rapid degradation of the drug. Conclusions: Although scaffold-mediated local chemotherapy holds a great potential to replace conventional chemotherapy as a postsurgical treatment modality, several practical limitations need to be addressed. Modification in the research methodology including a shorter time for preparing the scaffold and freeze-drying the scaffold material using lyophilization instead of normal drying could prevent degradation of the drug.
