Effect of Perioperative Blood Transfusion on Prognosis after Radical Resection in Patients with Non-Metastatic Renal Cell Carcinoma: A Retrospective Analysis.

OBJECTIVE

Advancements in medical science have improved non-metastatic renal cell carcinoma (NM-RCC) treatment strategies, but long-term survival is influenced by various factors, including perioperative blood transfusion. This study aims to analyse prognostic factors in patients with NM-RCC after radical nephrectomy.

METHODS

From January 2018 to December 2021, a total of 132 patients with NM-RCC after radical nephrectomy were studied. According to 2-year follow-up data, the patients were categorised into case (with poor outcomes, including pneumothorax, renal issues, recurrence or death) and control groups. Data on demographics, clinical characteristics and perioperative blood transfusion were collected, and key prognostic factors were identified through logistic regression.

RESULTS

A total of 32 patients with poor prognosis were included in the case group, accounting for 24.24% (32/132), and 100 patients without poor prognosis were included in the control group, accounting for 75.76% (100/132). Tumour stage, tumour size and perioperative blood transfusion were all risk factors for the prognosis of patients, and odds ratio (OR) >1. The above indicators had high predictive value for the prognosis of patients after surgery.

CONCLUSIONS

The prognostic factors of patients with NM-RCC after radical nephrectomy include tumour stage, tumour size and perioperative blood transfusion, and each factor had predictive value.
