Abstract
Pancreatic cancer comprises different subtypes, where most cases include ductal adenocarcinoma (PDAC). It is one of the deadliest tumor types, with a poor prognosis. In the majority of patients, the disease has already spread by the time of diagnosis, making full recovery unlikely and increasing mortality risk. Despite developments in its detection and management, including chemotherapy, radiotherapy, and targeted therapies as well as advances in immunotherapy, only in about 13% of PDAC patients does the overall survival exceed 5 years. This may be attributed, at least in part, to the highly desmoplastic tumor microenvironment (TME) that acts as a barrier limiting perfusion, drug delivery, and immune cell infiltration and contributes to the establishment of immunologically 'cold' conditions. Therefore, there is an urgent need to unravel the complexity of the TME that promotes PDAC progression and decipher the mechanisms of pancreatic tumors' resistance to immunotherapy. In this review, we provide an overview of the major cellular and non-cellular components of PDAC TME, as well as their biological interplays. We also discuss the current state of PDAC therapeutic treatments and focus on ongoing and future immunotherapy efforts and multimodal treatments aiming at remodeling the TME to improve therapeutic efficacy.

KARAYİĞİT A, ÖZDEMİR DB, DİZEN H, ÜNAL B. Factors independently associated with prognosis in patients operated for pancreatic cancer: Assessing the role of various parameters including red cell distribution width, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio. JOURNAL OF HEALTH SCIENCES AND MEDICINE 2022.

Abstract
Objective: We aimed to assess whether, among other parameters, preoperative red cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) values were associated with prognosis in patients operated for pancreatic cancer (PC).
Material and Method: This retrospective cohort was conducted from February 1, 2016 to February 1, 2021 at the general surgery department of a university hospital in Turkey. A total of 75 patients histologically diagnosed with PC who had undergone surgery were included in the study.
Results: The PLR values of patients with poorly differentiated and undifferentiated tumors were found to be higher than those with moderately and highly differentiated tumors. Also, there was a significant relationship between PLR values and the length of hospital stay. PLR values increased as the length of hospital stay increased. There was a statistically significant positive correlation between CA 19-9 levels and NLR and PLR. High total bilirubin level was related with increased risk of death, while adjuvant chemotherapy recipients had 4.049-fold lower risk of death than those without adjuvant chemotherapy.
Conclusion: Our results indicate that preoperative NLR, PLR and RDW cannot be used as prognostic indicators of mortality in patients with operated PC, but high PLR appears to be associated with lower level of tumor differentiation and prolonged hospital stay. We also found that high total bilirubin was a poor prognostic factor, while adjuvant chemotherapy was a good prognostic factor. Further multicenter, prospective studies with larger sample sizes will help to verify these results.

Impact of G-CSF Prophylaxis on Chemotherapy Dose-Intensity, Link Between Dose-Intensity and Survival in Patients with Metastatic Pancreatic Adenocarcinoma. Oncologist 2022; 27:e571-e579. [PMID: 35289915 PMCID: PMC9255980 DOI: 10.1093/oncolo/oyac055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 01/26/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND In metastatic pancreatic adenocarcinoma, few data are available on the use of granulocyte-colony stimulating factor (G-CSF) prophylaxis and its impact on dose-intensity (DI), or the link between DI and progression-free survival (PFS). This study assessed the impact of G-CSF prophylaxis on the DI received by patients and the relationship between full DI and PFS according to chemotherapy regimens. PATIENTS AND METHODS Patients from three first-line randomized phase II clinical trials were included in this retrospective cohort. G-CSF prophylaxis groups were identified and balanced according to baseline characteristics using a propensity score. Patients were classified into 2 treatment groups (FOLFIRINOX vs FOLFIRI/nab-paclitaxel (NAB)). DI was a binary variable (full/reduced). Adverse events were defined using NCI-CTCAE v4.0. RESULTS Of the 498 patients, 154 (31%) were in "prophylaxis" group; 179 (36%) were treated by FOLFIRINOX and 319 (64%) by FOLFIRI/NAB. In FOLFIRINOX group, G-CSF prophylaxis was significantly associated with a higher rate of full DI (OR, 5.07; 95% CI, 1.52-16.90; P < .01) while in FOLFIRI/NAB group, it was significantly associated with a lower rate of full DI (OR, 0.23; 95% CI, 0.06-0.83; P = .03). Full DI was associated with a non-significant increase in PFS (FOLFIRINOX group: HR 0.83; 95% CI, 0.59-1.16; P = .27; FOLFIRI/NAB group: HR 0.84; 95% CI, 0.63-1.11; P = .22). CONCLUSION Granulocyte-colony stimulating factor prophylaxis was associated with a higher rate of full DI with FOLFIRINOX. Full DI was associated with a non-significant increase in PFS. These results need to be confirmed prospectively.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer mortality in the US. Recent studies have demonstrated survival benefits for FOLFIRINOX (5-FU, leucovorin, irinotecan, and oxaliplatin) and Gem/nab-P (gemcitabine/nab-paclitaxel) over gemcitabine. We aimed to evaluate the clinical outcomes of mPDAC before and after incorporating these newer regimens into the clinical practice. METHODS A retrospective study of patients with mPDAC at our institution between 2009 and 2018, who were followed up until December 2019. Overall survival (OS) and progression-free survival (PFS) were calculated using Kaplan-Meier survival analysis. Univariate and multivariable Cox regression analyses were used to explore predictors of survival. RESULTS A total of 394 patients with mPDAC were included: 122 (31%) were diagnosed 2009-2013 and 272 (69%) 2014-2018. In 2009-2013 cohort vs. 2014-2018 cohort, the median OS and PFS were similar (4 vs. 3.6 months, P = 0.5) and (2.3 vs. 2.5 months, P = 0.41), respectively. Age, ECOG-PS >1, serum albumin, neutrophil-to-lymphocyte ratio, and platelets-to-lymphocyte ratio were independent predictors of better OS. CONCLUSIONS In this study of real-world data, the median OS and PFS for all patients with mPDAC were equivalent before and after incorporating newer treatment regimens into the clinical practice.

Predictors of distant metastases in sinonasal and skull base cancer patients treated with surgery. Oral Oncol 2021; 122:105575. [PMID: 34689008 DOI: 10.1016/j.oraloncology.2021.105575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 10/09/2021] [Accepted: 10/12/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES Sinonasal and skull base tumors comprise a heterogeneous group of malignancies with a significant rate of distant recurrence (DR). The aim of this study was to analyze tumor and host factors, including pretreatment neutrophil-to-lymphocyte ratio (NLR), that predict DR in these patients. MATERIALS AND METHODS We retrospectively reviewed sinonasal tumors and/or tumors involving the skull base treated with surgery between 1973 and 2015 (n = 473). We stratified NLR using the top 5 percentile as cutoff. Factors predictive of outcome were determined by Cox proportional hazards model. RESULTS Most tumors were primary (81%) and 67% had skull base resection. The most common site was the nasal cavity (37%) and the most common histology was squamous cell carcinoma (34%). Most patients presented with advanced primary tumor stage (pT3/T4; 80%) and most had no regional neck disease (pNx/N0; 93%). A total of 104 patients developed DR. The 5-year overall and disease-specific survival for patients who developed DR were 36.4% and 35.8%, compared to 69.0% and 74.9% for patients who did not. Patients with DR had a higher percentage of NLR-high patients compared patients without DR (11% vs 3%, p = .006). In a multivariable analysis, melanoma histology (HR = 5.469, 95% CI 3.171-9.433), pT3/T4 (HR = 2.686, 95% CI 1.150-6.275), pN+ (HR = 6.864, 95% CI 3.450-13.653), and NLR-high (HR = 3.489, 95% CI 1.593-7.639) were independent predictors of DR. CONCLUSION Melanoma histology, pT, pN, and high NLR predict DR, suggesting that both tumor and host factors need to be considered. NLR may act as a surrogate marker of the host́s immune system.

Abstract
Background Biomarkers of systemic inflammation (BMSIs), including haemogram cell counts (CC, e.g., absolute neutrophil count) and cell count-ratios (CCR, e.g., the neutrophil-lymphocyte ratio, etc.), have been found to have prognostic significance in many solid-organ cancers. Aims In this three-part study, we first examined if the CCs and CCRs were altered in patients with glioblastoma (GBM) when compared with healthy controls. Second, we evaluated for any correlation between the BMSIs and patient- and tumour-related factors. Third, we evaluated the influence of the CCs and CCRs on survival. Methods This was a retrospective analysis of patients who underwent surgery/biopsy for a newly diagnosed brain tumour that was subsequently confirmed to be GBM (Cases). Controls were healthy individuals who underwent pre-employment screening blood tests. Statistical Methods Parametric tests were used to compare normally distributed continuous variables, whereas non-normally distributed variables were compared using non-parametric tests. Thresholds for the BMSIs were determined using X-tile analysis. Cox regression using the proportional hazards model was used for survival analyses around the determined thresholds. Results All CCs and CCRs were altered in Cases compared with Controls. Presentation with raised intracranial pressure, altered sensorium, poor performance status, loss of ATRX, and lack of p53 overexpression was associated with an inflammatory phenotype of changes in the BMSIs. The inflammatory phenotype of changes was associated with poor survival. Conclusions A significant inflammatory response was found in patients with GBM and correlated with clinical features, the molecular profile of the tumour and poor survival.

Abstract
Adjuvant chemotherapy is currently used in all patients with resected pancreatic cancer who are able to begin treatment within 3 months after surgery. Since the recent publication of the PRODIGE 24 trial results, modified FOLFIRINOX has become the standard-of-care in the non-Asian population with localized pancreatic adenocarcinoma following surgery. Nevertheless, there is still a risk of toxicity, and feasibility may be limited in heavily pre-treated patients. In more frail patients, gemcitabine-based chemotherapy remains a suitable option, for example gemcitabine or 5FU in monotherapy. In Asia, although S1-based chemotherapy is the standard of care it is not readily available outside Asia and data are lacking in non-Asiatic patients. In patients in whom resection is not initially possible, intensified schemes such as FOLFIRINOX or gemcitabine-nabpaclitaxel have been confirmed as options to enhance the response rate and resectability, promoting research in adjuvant therapy. In particular, should oncologists prescribe adjuvant treatment after a long sequence of chemotherapy +/- chemoradiotherapy and surgery? Should oncologists consider the response rate, the R0 resection rate alone, or the initial chemotherapy regimen? And finally, should they take into consideration the duration of the entire sequence, or the presence of limited toxicities of induction treatment? The aim of this review is to summarize adjuvant management of resected pancreatic cancer and to raise current and future concerns, especially the need for biomarkers and the best holistic care for patients.

Abstract
Purpose. To evaluate the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio(PLR) value in the development of branch retinal vein occlusion (BRVO)patients. Methods. 81 patients with BRVO and 81 age and sex-matched subjects were recruited as the control group. The BRVO diagnosis was confirmed under comprehensive ophthalmologic examinations. NLR and PLR parameters obtained from peripheral blood were recorded. Results. Both the mean NLR and PLR was significantly higher in the BRVO group compared with the control group (p < 0.001). In ROC analysis, the AUC for NLR was 0.82, and NLR of >2.48 predicted BRVO with a sensitivity of 58% and specificity of 98%. The AUC for PLR was 0.78, and PLR of >110.2 predicted BRVO with a sensitivity of 72% and specificity of 72%. Conclusion. The current study demonstrated that BRVO patients had increased NLR and PLR levels compared with control subjects. The NLR and PLR may be used as independent predictors for identifying risk for the development of BRVO.

Abstract
Objectives: To investigate the intercourse between the platelet/lymphocyte (P/L) and neutrophil/lymphocyte ratio (N/L), and vitamin D (Vit-D) levels in low bone mineral density (BMD) of women. Methods: Two hundred fifty-two postmenopausal female outpatients who were admitted to the obstetrics and gynecology and physical therapy clinics between July 2016 and December 2017 were retrospectively analyzed. The patients were grouped in relation to their T-score (normal [n=92], osteopenia [n=112], and PMO [n=48]). The serum levels of P/L, N/L, Vit-D, BMD and complete blood count of the patients were retrospectively examined. Results: The median P/L was significantly higher and Vit-D levels were significantly lower in the PMO group (130.75 [52.89-385] versus 123.05 [54-232.5], p=0.02 and 15.4 [4-34] versus 20.1 [4-47], p=0.003). While BMD and P/L were negatively correlated, a positive correlation between BMD and Vit-D was found. Vitamin D levels were negatively correlated with P/L (p<0.001) and N/L (p=0.04). Older age (≥65 years), Vit-D deficiency and P/L values >125.06 were found as independent prognostic factors for PMO in regression analysis. Conclusion: Higher P/L seems to be a quite simple marker to help predict postmenopausal PMO. As seen in our study, having low levels of Vit-D is crucial for PMO.
