Abstract
BACKGROUND: Sarcomatoid change in Renal cell carcinoma(RCC) is associated with adverse outcomes with median survival of 6 months. SETTINGS AND DESIGN: This is a retrospective study of patients diagnosed of sarcomatoid RCC(sRCC) between 2007 and 2013 which were followed up till 2017. METHODS AND MATERIAL: Patients (n=22) were grouped based on whether they received additional chemotherapy following nephrectomy. Two groups were followed up until 2017 and overall survival was record. Overall survival curves were estimated by Kaplan-Meier method and compared using Log Rank (Mantel-Cox) test between two groups. STATISTICAL ANALYSIS USED: Kaplan-Meier method and Log Rank (Mantel-Cox) test. RESULTS: The patients who had chemotherapy had 13.4 cm of mean tumour size with a mean survival of 20.4 ± 8.3 months. The patients who did not undergo chemotherapy had mean tumour size of 11.7 cm with a mean survival of 21 ± 5.9 months. There was no much statistical difference between the two groups in OS with P value = 0.99. CONCLUSION: The current adjuvant chemotherapy used in sRCC patients who develop metastasis gives no survival advantage.
