Purpose. Grade-dependent decrease of lipid storage in clear cell renal cell carcinoma (ccRCC) leads to morphology changes in HE sections. This study investigated the role of cytoplasmic features in frozen sections of ccRCC on prognosis using the digital pathology approach. Methods. We established an automatic pipeline that performed tumor region selection, stain vector normalization, nuclei segmentation, and feature extraction based on the pathologic data from Shanghai General Hospital and The Cancer Genome Atlas database. Extracted features were subjected to survival analysis. Results. Kurtosis of the cytoplasm in the hematoxylin channel was correlated with progression-free survival (HR 0.10, 95% CI: 0.04–0.24, p = 6.52 ∗ 10 − 7 ) and overall survival (HR 0.11, 95% CI: 0.05–0.31, p = 1.72 ∗ 10 − 5 ) in ccRCC, which outperformed other texture features in this analysis. Multivariate Cox regression analysis revealed that low kurtosis of cytoplasm in the hematoxylin channel was an independent predictor for a shorter progression-free survival time ( p = 0.044 ) and overall survival time (p = 0.01). Kaplan–Meier survival analysis of progression-free survival and overall survival also showed a significantly worse prognosis in patients with low kurtosis of the cytoplasm in the hematoxylin channel (both p < 0.0001 ). Lower kurtosis of cytoplasm in the hematoxylin channel was associated with higher pathologic grade, less cholesterol ester, and more mitochondrial DNA content. Conclusion. Kurtosis of the cytoplasm in the hematoxylin channel predicts survival in clear cell renal cell carcinoma.

Introduction: Limited data exists on utilization of protein post-translational modifications as biomarkers for clear cell renal cell carcinoma (ccRCC). We employed high-throughput glycoproteomics to evaluate differential expression of glycoprotein-isoforms as novel markers for ccRCC progression-free survival (PFS). Methods: Plasma samples were obtained from 77 patients treated surgically for ccRCC. Glycoproteomic analyses were carried out after liquid chromatography tandem mass spectrometry. Age-adjusted Cox proportional hazard models were constructed to evaluate PFS. Optimized Harrells c-index was employed to dichotomize the collective for the construction of Kaplan-Meier curves. Results: The average length of follow-up was 3.4 (range: 0.04-9.83) years. Glycoproteomic analysis identified 39 glycopeptides and 14 non-glycosylated peptides that showed statistically significant (false discovery rate p ≤0.05) differential expression associated with PFS. Five of the glycosylated peptides conferred continuous hazard ratio of > 6 (range 6.3-11.6). These included prothrombin A2G2S glycan motif (HR=6.47, P=9.53E-05), immunoglobulin J chain FA2G2S2 motif (HR=10.69, P=0.001), clusterin A2G2 motif (HR=7.38, P=0.002), complement component C8A A2G2S2 motif (HR=11.59, P=0.002), and apolipoprotein M glycopeptide with non-fucosylated and non-sialylated hybrid-type glycan (HR=6.30, P=0.003). Kaplan-Meier curves based on dichotomous expression of these five glycopeptides resulted in hazard ratios of 3.9-10.7, all with p-value < 0.03. Kaplan-Meyer plot using the multivariable model comprising 3 of the markers yielded HR of 11.96 (p <0.0001). Conclusion: Differential glyco-isoform abundance of plasma proteins may be a useful source of biomarkers for the clinical course and prognosis of ccRCC.

Objective: We aimed to evaluate the role of intra-tumoral CXCR1 expression in predicting prognosis and treatment response in metastatic clear-cell renal cell carcinoma patients receiving tyrosine kinase inhibitors. Materials and methods: Patients with metastatic clear-cell renal cell carcinoma presented between February 2018–December 2019 were studied for the CXCR1 expression in tumor tissues before starting tyrosine kinase inhibitors. Primary outcome measure was progression-free survival. Secondary outcome measures included overall survival and prediction of treatment response. Results: The study included 35 patients with a mean age of 53.6±9.6 years. At a mean follow-up of 12.2±4.1 months, 17 (48.6%) patients had disease progression including eight (22.9%) deaths. Patients with high CXCR1 expression, compared to those with low CXCR1 expression, had a significantly shorter 12-month progression-free survival (35.4% vs 77.9%, p=0.01) and an insignificant impact on 12-month overall survival. The CXCR1 expression scores significantly differed between patients with progressive and nonprogressive disease (20.1 vs 15.1, p=0.01) and patients with high CXCR1 expression had a reduced benefit from tyrosine kinase inhibitors. The multivariate Cox regression analysis showed CXCR1 expression as a significant predictor of progression-free survival. Conclusion: High intra-tumoral CXCR1 expression before tyrosine kinase inhibitors can be an independent prognostic factor for progression-free survival and predictor of reduced benefit in patients with metastatic clear-cell renal cell carcinoma. Level of evidence: Level 2b.

Abstract Purpose Combined immunotherapy of nivolumab plus ipilimumab for intermediate- and poor-risk metastatic clear cell renal cell carcinoma showed prolonged progression-free survival and high objective response rate in a randomized phase III clinical trial. However, the efficacy of this treatment for papillary renal cell carcinoma remains unclear. In the present study, we analysed the efficacy of nivolumab plus ipilimumab therapy for papillary renal cell carcinoma compared with that for clear cell renal cell carcinoma. Materials and Methods This is a retrospective study of 30 patients with metastatic renal cell carcinoma who received nivolumab and ipilimumab as first-line therapy between December 2015 and May 2020. The objective response rate, progression-free survival and toxicity were compared between the two groups (clear cell renal cell carcinoma and papillary renal cell carcinoma). Results Out of 30 patients, 7 and 23 were diagnosed with papillary renal cell carcinoma and clear cell renal cell carcinoma, respectively. With a median follow-up of 7.2 months, the median progression-free survival was significantly shorter in papillary renal cell carcinoma than in clear cell renal cell carcinoma (2.4 vs. 28.1 months, P = 0.014). Of the seven patients with papillary renal cell carcinoma, one had partial response, one had stable disease and five had progressive disease, resulting in an objective response rate of 14.2%, which was lower compared to that of clear cell renal cell carcinoma (14.2 vs. 52.1%, P = 0.06). Discontinuation due to toxicity was not observed with papillary renal cell carcinoma, meanwhile 60.8% of patient with clear cell renal cell carcinoma discontinued treatment due to toxicity. Conclusion Nivolumab plus ipilimumab had modest efficacy for papillary renal cell carcinoma compared with that for clear cell renal cell carcinoma. Nivolumab plus ipilimumab remains an option for a limited number of patients with intermediate- or poor-risk papillary renal cell carcinoma.

Beta-1,4-galactosyltransferase II is found to be associated with the alterations of tumor-related glycosylation. However, the clinical significance of beta-1,4-galactosyltransferase II in non-metastatic clear-cell renal cell carcinoma has not been reported up to now. Herein, our researches suggested that the expression level of beta-1,4-galactosyltransferase II was first found to be positively associated with tumor size, Fuhrman grade, lymphovascular invasion, rhabdoid differentiation, tumor necrosis and poor overall survival and recurrence-free survival of patients with non-metastatic clear-cell renal cell carcinoma, both in training set and validation set. Moreover, beta-1,4-galactosyltransferase II expression was identified as an independent adverse prognosticator for overall survival and recurrence-free survival of patients with non-metastatic clear-cell renal cell carcinoma. Ultimately, prognostic accuracy of the nomogram integrating beta-1,4-galactosyltransferase II with other independent prognostic parameters was dramatically improved for overall survival and recurrence-free survival of patients with non-metastatic clear-cell renal cell carcinoma. Taken together, beta-1,4-galactosyltransferase II is a potential independent adverse prognostic factor for postoperative recurrence and survival, which could be developed as a useful biomarker for non-metastatic clear-cell renal cell carcinoma by a series of further independent and retrospective studies, so as to help the postsurgical management of clear-cell renal cell carcinoma patients.
