RESUMEN

BACKGROUND: To evaluate the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced nonmetastatic clear cell renal cell carcinoma (ccRCC) undergoing radical nephrectomy. MATERIAL AND METHODS: We retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, reviewed data from 478 radical nephrectomies for kidney tumors and identified 187 patients with locally advanced nonmetastatic ccRCC (pT3-T4 N0M0). NLR was obtained preoperatively and calculated by dividing absolute neutrophil count by absolute lymphocyte count. OS and RFS were evaluated by the Kaplan-Meier method. Cox proportional-hazards regression models were used to evaluate predictors of RFS and OS. RESULTS: Among 187 patients with ccRCC (mean age 63.4 ± 11.5 years; 118 [63.1%] male), the median follow-up was 48.7 months. On univariate analysis, in patients with Fuhrman nuclear grade of differentiation 3-4, the median time to recurrence was significantly shorter with NLR ≥ 4 than < 4 (24 vs. 55 months, P = .045). On multivariable analysis adjusted for NLR ≥ 4, among all variables analyzed (NLR, microvascular invasion, sarcomatoid differentiation, tumor size and body mass index), only nuclear grade of differentiation was an independent predictor of recurrence (hazard ratio 2.18; 95% confidence interval 1.07-4.92, P = .03). The 3-year OS had no statistically significant difference between patients with NLR ≥ 4 or < 4. CONCLUSION: For patients with locally advanced, nonmetastatic ccRCC, RFS was reduced with high nuclear grade of differentiation and high preoperative NLR. These findings suggest an association between higher NLR and worse outcomes in locally advanced ccRCC.

RESUMEN

PURPOSE: Reported treatment outcomes for patients with advanced germ cell tumors (aGCT) are based mainly on series from developed nations. Data from low- and middle-income countries are underrepresented. MATERIAL AND METHODS: From 2000 to 2015, a retrospective analysis identified 300 patients with aGCT treated at our institution. Kaplan-Meier methods were used for analysis of progression-free survival (PFS) and overall survival (OS) according to the International Germ Cell Consensus Classification Group (IGCCCG). RESULTS: Patients' median age was 28 years. According to the IGCCCG, 57% had good-, 18.3% intermediate-, and 24.7% poor-risk disease. Median α-fetoprotein levels were 2.9, 243, and 3,998 ng/mL, and those of human chorionic gonadotropin were 0.4, 113, and 301.5 mUI/mL in IGCCCG good-, intermediate-, and poor-risk groups, respectively. At a median 46 months of follow-up, 93 PFS events and 45 deaths had occurred and estimated 5-year PFS and OS were 69% and 85%, respectively, including 83% and 95.3% in good-risk, 70.9% and 83.6% in intermediate-risk, and 35.1% and 62.2% in poor-risk patients, respectively. In multivariable analysis, Eastern Cooperative Oncology Group performance status ≥ 2 was a significant independent prognostic factor with a hazard ratio of 2.58 (95% CI, 1.55 to 4.29; P < .001) and 6.20 (95% CI, 2.97 to 12.92; P < .001) for PFS and OS, respectively. CONCLUSION: Brazilian patients with aGCT in this cohort had similar outcomes as patients in the IGCCCG database. In comparison with contemporary series, patients with intermediate- and poor-risk aGCT had slightly inferior PFS and OS, possibly due to a high percentage of patients with poor performance status and less use of high-dose chemotherapy.

RESUMEN

CONTEXT: Lipodystrophy syndromes are rare disorders characterized by the selective loss of adipose tissue. We aimed to report a case of acquired generalized lipodystrophy possibly associated with nivolumab. CASE DESCRIPTION: A woman was referred to our Endocrinology Department for uncontrolled diabetes mellitus. At 50 years of age, she was diagnosed with type 2 diabetes after a routine laboratory test and her diabetes was well controlled with low doses of metformin. In 2010, she was diagnosed with clear cell renal carcinoma. The cancer progressed in the following years, leading to the initiation of treatment with nivolumab in 2017. Two months later she presented with facial lipoatrophy, with loss of the buccal fat pads and prominent zygomatic arch. Her neck, shoulders, arms, and buttocks were also affected. Her diabetes control worsened. She received maximal doses of metformin and pioglitazone and was administered 1.5 units/kg/d insulin. Subcutaneous biopsy of medial surface of the arm revealed chronic lobular panniculitis. Despite nivolumab's possible involvement in the onset of lipodystrophy, the maintenance of nivolumab therapy was justified by the observed reduction in the progression of the cancer, combined with the lack of an alternative chemotherapy. The therapy was withdrawn after 8 months of treatment because of grade 3 hepatitis. CONCLUSION: Anti-PD1 therapy has great potential. Early recognition of the onset of unusual collateral effects is important to improve decision making regarding the treatment of patients with tumors.
