The Clinical Impacts of Pretreatment Peripheral Blood Ratio on Lymphocytes, Monocytes, and Neutrophils Among Patients with Laryngeal/Hypopharyngeal Cancer Treated by Chemoradiation/Radiation. Cancer management and research PURPOSE:This study aimed to investigate the clinical impacts of the pretreatment peripheral blood ratios of lymphocytes, monocytes and neutrophils among patients with hypopharyngeal cancer/laryngeal cancer. PATIENTS AND METHODS:A total of 141 people with cases of hypopharyngeal cancer/laryngeal cancer were enrolled to evaluate the clinical impacts of the systemic inflammation response index (SIRI), neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR) in pretreatment blood among patients with laryngeal/hypopharyngeal cancer between January 2012 and December 2014. RESULTS:Those patients with higher pretreatment LMR (>2.99) showed a significantly higher 5-year complete response rate (CR) (69% vs 31%) than those with lower LMR (≤2.99, = 0.006). Additionally, those patients with lower pretreatment SIRI (<3.26) showed a significantly higher 5-year CR (90% vs 10%) than those with higher SIRI (≥3.26, < 0.001). Patients with higher LMR had better 5-year overall survival (OS) ( = 0.01) and 5-year progression-free (PFS) ( = 0.005) rates than those with lower LMR in univariate analysis. Patients with lower SIRI had better 5-year OS ( < 0.001) and 5-year PFS ( < 0.001) than those with higher SIRI in univariate analysis. In the Cox regression analysis, SIRI (HR = 1.941, [95% CI: 1.223-3.081], = 0.005) and N classification (HR = 2.203, [95% CI: 1.327-3.657], = 0.002) were independent variables of 5-year OS. In addition, SIRI (HR= 2.127, [95% CI: 1.214-3.725], = 0.008), T classification (HR = 2.18, [95% CI: 1.072-4.433], = 0.031), and N classification (HR = 2.329, [95% CI: 1.395-3.889], = 0.001) were independent variables of 5-year PFS. CONCLUSION:Pretreatment SIRI is superior to LMR in predicting treatment response and clinical outcomes among patients with laryngeal/hypopharyngeal cancer treated by CRT/RTO. SIRI may be adopted in the treatment of laryngeal/hypopharyngeal cancer by CRT/RTO. 10.2147/CMAR.S275635

Serum Albumin as a Predictor of Survival after Interval Debulking Surgery for Advanced Ovarian Cancer (AOC): A Retrospective Study. Journal of investigative surgery : the official journal of the Academy of Surgical Research OBJECTIVE:To investigate the impact of serum albumin (at diagnosis and pre-operatively) on survival in patients undergoing cytoreductive surgery for advanced ovarian cancer(AOC) and whether improvement in albumin achieved following neoadjuvant chemotherapy (NACT) affects overall survival (OS). METHODS:Outcomes of 441 patients who underwent cytoreduction for AOC were reviewed. Albumin was recorded at diagnosis and pre-operatively. Further analysis was performed if patients were hypoalbuminaemic at diagnosis.Analysis was stratified according to whether the patientreceived primary debulking surgery (PDS) or interval debulking surgery (IDS) and if their albumin was corrected. RESULTS:308 patients had a serum albumin level at diagnosis and 400 patients had a pre-operative albumin available for analysis. For patients with an albumin at diagnosis ≤ 35g/L and ≥36 g/L, median OS was 31.5 (95% CI 23.5-39.5) and 50.4 (95% CI 38.9-61.9) months respectively (P = 0.003). Followingmultivariate analysis (MVA), albumin at diagnosis remained statistically significant as an independent marker for survival, even after adjusting for cytoreductive outcome, stage and grade(p = 0.04, Hazard ratio 1.38, 95% CI 1.01-1.89).Hypoalbuminaemic patients at diagnosis achieved complete cytoreduction in 53% of cases.For PDS patients, median OS was 19.7 months (95% CI 11.5-27.9). For IDS patients, median OS was 27.9 months (n = 1).IDS patients with a corrected albumin had a median OS of 42.9 months (95% CI 31.5-54.3) (p > 0.05). CONCLUSION:Hypoalbuminaemia at diagnosis is a poor prognostic factor in AOC. Normalization of serum albumin after NACT is a potential predictor of survival. 10.1080/08941939.2020.1827314

Tumor associated neutrophils promote the metastasis of pancreatic ductal adenocarcinoma. Cancer biology & therapy The aim of this study was to investigate the role of tumor-associated neutrophils (TANs) in the metastasis of pancreatic ductal adenocarcinoma (PDAC), to explore the regulation of TANs, and to determine the mechanisms governing the metastasis of PDAC. The correlation between neutrophils and the patient's clinical pathological data was first evaluated. Then, the effects of neutrophils on the invasion of PDAC were analyzed using a combination of conditioned media, direct and indirect coculture of human peripheral blood neutrophils, and PDAC cell lines (Panc-1, MiaPaCa-2 and AsPC-1). The cytokines secreted by neutrophils were detected through ELISA. TAN density was significantly correlated with poor metastasis-free survival ( < .05). Through coculture, it was found that the effect of neutrophils on pancreatic cancer cells was dependent on concentration, and a high concentration of neutrophils showed a lethal effect, while a low concentration of neutrophils primarily promoted the migration ability of cancer cells. The results of the wound-healing assay, the Transwell invasion assay, and laser confocal microscopy confirmed the promoting effect and indicated that the effect of neutrophils toward cancer cells may function indirectly by releasing a series of cytokines. The results of ELISA show that this effect may be achieved through the secretion of a large amount of TNF-α and TGF-β1 by neutrophils. Our study indicated that neutrophils may increase the metastasis of PDAC by releasing a series of cell cytokines, such as TNF-α and TGF-β1. 10.1080/15384047.2020.1807250

Carboplatin re-treatment in platinum-resistant epithelial ovarian cancer patients. Hansen Mads Kingo Guldberg,Smerdel Maja Patricia,Waldstrøm Marianne,Andersen Rikke Fredslund,Adimi Parvin,Jakobsen Anders,Steffensen Karina Dahl Cancer chemotherapy and pharmacology PURPOSE:Treatment of multi-resistant epithelial ovarian cancer represents a clinical challenge with limited choices. Anti-angiogenic therapy has shown great potential in combination with frontline-therapy. Studies investigating heavily pre-treated patients are few. This study investigated the effect of re-treating patients with carboplatin combined with bevacizumab and cell-free DNA (cfDNA) as a potential predictor of outcome. METHODS:This single-center study enrolled 73 multi-resistant ovarian cancer patients from 2008 to 2015. Patients were treated with a combination of bevacizumab (10 mg/kg) and carboplatin (AUC5) every 3 weeks. Baseline plasma samples were analyzed for cfDNA levels. Treatment response was evaluated based on the Response Evaluation Criteria in Solid Tumors (RECIST) criteria and CA125 blood values. RESULTS:The response rate according to RECIST and/or CA125 was 57%. Median number of cycles was 6. The median progression-free survival and overall survival was 5.0 and 11.2 months, respectively. Eighteen patients developed allergic reactions to carboplatin. Patients were grouped into two cfDNA-groups according to median value. The cfDNA value was correlated to progression-free survival (PFS, p = 0.015), but not to overall survival (OS, p = 0.067) in the univariate analysis. In the multivariate analysis both PFS and OS were highly correlated to the levels of cfDNA (PFS, hazard ratio = 1.87, p = 0.012; OS, hazard ratio = 1.67, p = 0.037) with patients with high levels of cfDNA having poorest outcome. CONCLUSION:Our results might provide guidance in cases with heavily pre-treated patients, where alternatives are limited. Carboplatin and bevacizumab treatment should be weighed against best supportive care, current non-platinum therapies and experimental treatment. cfDNA seems to offer prognostic insight. 10.1007/s00280-020-04162-5
