Mining and validation of prognosis of various visceral metastasis in renal cell carcinoma: a study based on SEER database

AbstractOur study was aimed to analyze a substantial of renal cell carcinoma (RCC) patients, research the high-risk factors and prognostic factors of metastasis, and thoroughly examine the effects of primary site surgery, lymph node dissection (LND), and chemotherapy on the prognosis of different visceral metastases. The baseline characteristics were characterized, and logistic regression was used to predict the risk factors for metastasis. Prognostic factors of metastatic RCC were assessed using batch univariate and multivariate Cox regression, with adjustments made through PSM. Next, the Kaplan –Meier method was employed to assess OS and create the survival curve. Logistic regression identified risk factors for metastasis: male gender [OR, 1.223;P <  0.001], Hist clear (OR, 9.37;P <  0.001), Hist papillary (OR, 2.49;P <  0.001), and TTX (OR, 23.33;P <  0.001). We found several independent prognostic variables: among which chemotherapy (HR, 0.64), local LND (HR, 0.67), and primary site surgery (HR, 0.97) were associated with better OS. Further study results demonstrated that all kinds of visceral metastasis except for liver metastasis in the ope ration group had substantially better prognoses than those in the non-operation group (P <  0.05). Regional LND had no discernible impact on survival. Patients with liver, lung, and distant lymph node (LN) metastasis benefited from chemotherapy (P <  0.05), but the bone and brain metastasis...
