Background: The purpose of this study was to compare the occurrence of cisplatin-induced nephrotoxicity between concomitant chemoradiotherapy with high versus intermediate-dose cisplatin.
Methods: One hundred forty-four patients with locally advanced head and neck or nasopharyngeal cancer (NPC) were included; 40 patients received cisplatin 100 mg/m(2) (high dose) on days 1, 22, and 43, and 104 patients received cisplatin 40 mg/m(2) weekly (intermediate dose) during 6 weeks in combination with radiotherapy.
Results: During treatment with intermediate-dose cisplatin, 6.7% developed an increase of ≥50% serum creatinine versus 60.0% treated with high-dose cisplatin (p < .05). Nephrotoxicity (all grades) scored by Common Toxicity Criteria for Adverse Events (CTCAE) version 3.0 or CTCAE version 4.03 was 53% and 100% in the high-dose group and 4.8% and 68% in the intermediate-dose group, respectively.
Conclusion: Significantly less nephrotoxicity occurs during chemoradiotherapy with intermediate-dose cisplatin compared with high-dose cisplatin. The CTCAE version 4.03 seems to be more appropriate in scoring nephrotoxicity than the CTCAE version 3.0. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1575-E1581, 2016.

The NS1 binding protein, known for interacting with the influenza A virus protein, is involved in RNA processing, cancer, and nerve cell growth regulation. However, its role in stress response independent of viral infections remains unclear. This study investigates NS1 binding protein's function in regulating stress granules during oxidative stress through interactions with GABARAP subfamily proteins.

Although CCL17 has been reported to exert a vital role in many cancers, the related studies in the thyroid carcinoma have never reported. As a chemokine, CCL17 plays a positive role by promoting the infiltration of immune cells into the tumor microenviroment (TME) to influence tumor invasion and metastasis. Therefore, this study is aimed to investigate the association of CCL17 level with potential prognostic value on tumor immunity in the thyroid carcinoma (THCA) based on the bioinformatics analysis.

Approximately 90% of glioblastoma recurrences occur in the peritumoral brain zone (PBZ), while the spatial heterogeneity of the PBZ is not well studied. In this study, two PBZ tissues and one tumor tissue sample are obtained from each patient via preoperative imaging. We assess the microenvironment and the characteristics of infiltrating immune/tumor cells using various techniques.
