The aim of this study was to evaluate the prognostic relevance of preoperative absolute lymphocyte count (ALC) in patients with papillary renal cell carcinoma (RCC). METHODS We retrospectively analyzed our institutional, prospectively maintained, renal cancer database and identified patients with pathologic diagnosis of papillary RCC after partial or radical nephrectomy. Patients with preoperative ALC value within 3 months prior to surgery were eligible for the study. ALC of 1,300 cells/μl was used as the cutoff value (our lowest laboratory reference value). We evaluated the correlation between ALC and age, gender, Charlson comorbidity index (CCI), smoking history, pathologic T stage, nuclear grade, and overall TNM stage with linear regression or trend tests. Differences in overall survival (OS) by ALC status were assessed using the log−rank test. Cox proportional hazards modeling was used for multivariable analyses. RESULTS We identified 293 out of 2,732 patients with a pathologic diagnosis of papillary RCC after partial or radical nephrectomy from 1997 to 2013. Those undergoing multiple surgical procedures (multifocal or bilateral disease) or missing preoperative ALC were excluded from the study. A total 192 patients met inclusion criteria with a median follow up of 37.3 months. As a continuous variable, low absolute lymphocyte count was associated with higher pT stage (p=0.001), TNM stage (p=0.001) and older age (p=0.012). Lymphopenia below 1,300 cells/μl was also associated with pT stage (p<0.001) and TNM stage (p=0.003). On multivariable analysis, independent of stage, age, CCI, and history of smoking, lymphopenia was associated with inferior overall survival (HR 2.15 [CI 1.08-4.29], p=0.030). CONCLUSIONS In our series of patients with papillary renal cell carcinoma, lymphopenia was associated with lower overall survival independent of stage, age, history of smoking, and Charlson comorbidity index. ALC appears to be an independent prognostic factor for overall survival in papillary RCC patients, and can be helpful for preoperative patient counseling, tailoring individual patient surveillance schedule, and designing clinical trials. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e321-e322 Advertisement Copyright & Permissions© 2014Metrics Author Information Reza Mehrazin More articles by this author Robert G.
