Prognostic factors in renal cell carcinoma

Area of Science:

• Oncology
• Pathology

Background:

• Renal cell carcinoma (RCC) is a significant cause of cancer-related mortality.
• Identifying accurate prognostic factors is crucial for effective patient management and treatment strategies.

Purpose of the Study:

• To evaluate morphological and clinical prognostic factors in patients with renal cell carcinoma (RCC).
• To determine the significance of various factors in predicting patient survival.

Main Methods:

• Retrospective analysis of 166 patients diagnosed with renal cell carcinoma (RCC).
• Evaluation of clinical data including age, sex, tumor stage, grade, and size.
• Assessment of pathological features such as tumor weight, cell type, invasion, growth pattern, and presence of necrosis.

Main Results:

• Tumor stage, particularly metastasis, was the most significant prognostic factor for RCC survival (p < 0.001).
• Tumor grade (p = 0.0146) and the presence of necrotic areas (p = 0.0102) also showed prognostic value.
• Infiltrative growth pattern was associated with poorer prognosis compared to pushing type growth pattern (p = 0.0045).
• Tumor diameter and nephrectomy specimen weight were significant prognostic indicators.
• Patient age, sex, tumor location, renal vein invasion, pseudocapsules, intravascular tumor, mitotic rate, lymphocyte/macrophage presence, and calcifications did not significantly affect survival (p > 0.05).

Conclusions:

• Tumor stage, grade, necrotic areas, and growth pattern are key prognostic indicators for renal cell carcinoma (RCC).
• Clinical factors like age and sex, and certain pathological features, do not significantly influence RCC patient survival.
• Accurate pathological assessment is vital for predicting RCC outcomes and guiding treatment decisions.
