EFFICACY OF NEOADJUVANT TARGETED THERAPY IN TREATMENT OF PATIENTS WITH LOCALISED CLEAR-CELL RENAL CELL CARCINOMA

Clear-cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer, accounting for approximately 75-80% of all renal malignancies. Objectives: The main objective of the study is to find the efficacy of neoadjuvant targeted therapy in the treatment of patients with localised clear-cell renal cell carcinoma. Methods: This prospective study was conducted at Mardan Medical Complex from June 2023 to January 2024. Data were collected from 85 patients. Patients aged>18 years and have a histologically confirmed diagnosis of localized ccRCC were included in the study. Tumor size was required to be 4 cm or larger, but confined to the kidney, corresponding to Stage I to III disease. Results: Data were collected from 85 patients with an average baseline tumour size for the entire cohort was 7.5 cm, and after 12 weeks of treatment, tumours shrank to an average of 5.6 cm, resulting in a mean tumour reduction of 25%. In the sunitinib group, the tumour size decreased from 7.5 cm to 5.55 cm, reflecting a 26% reduction. Similarly, in the pazopanib group, the tumour size was reduced from 7.5 cm to 5.65 cm, with an average reduction of 24%. Conclusion: It is concluded that neoadjuvant targeted therapy, using agents such as sunitinib and pazopanib, effectively reduces tumour size and improves surgical outcomes in patients with localized clear-cell renal cell carcinoma.
