Assessing serum albumin concentration, lymphocyte count and prognostic nutritional index might improve prognostication in patients with myelofibrosis

Optimization of cardiovascular risk factor management in patients with BCR::ABL1 negative chronic myeloproliferative neoplasms, current knowledge, and perspectives

The exact prognostic role of cardiovascular (CV) risk factors in patients with BCR::ABL1 negative chronic myeloproliferative neoplasms (MPNs) remains unknown as it is often masked by other MPN-related features that bear strong prognostic impact on thrombotic risk. Therefore, current MPN treatment is not primarily guided by presence of CV risk factors. Treatment of CV risk factors in MPN patients usually mirrors that from the general population, despite the fact that CV risk factors in MPNs have their own specificities. Moreover, the optimal target levels for different metabolic deflections in MPNs (i.e., low-density lipoprotein, serum uric acid, or glycated hemoglobin levels) have not been defined. In the current review, we separately discuss the most important aspects of every individual CV risk factor (arterial hypertension, hyperlipidemia, chronic kidney disease, smoking, diabetes mellitus, hyperuricemia, and obesity and cachexia) in MPNs, summarize recent advances in the field, and propose future directions and research areas which may be needed to appropriately manage CV risk factors in MPNs.

Evaluation of Absolute Neutrophil, Lymphocyte and Platelet Count and Their Ratios as Predictors of Thrombotic Risk in Patients with Prefibrotic and Overt Myelofibrosis

AIM

To investigate the prognostic contribution of absolute neutrophil (ANC), lymphocyte (ALC), platelet count and their ratios, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR), to thrombotic risk in patients with prefibrotic and overt fibrotic myelofibrosis (MF).

METHODS

We retrospectively analyzed a cohort of 256 patients with prefibrotic (85 patients) and overt fibrotic MF (171 patients) treated in six Croatian hematological centers.

RESULTS

Prefibrotic compared to overt fibrotic MF patients presented with significantly higher ALC, platelet count and PLR, and experienced longer time to thrombosis (TTT). Among prefibrotic patients, ANC > 8.33 × 109/L (HR 13.08, p = 0.036), ALC > 2.58 × 109/L (HR 20.63, p = 0.049) and platelet count > 752 × 109/L (HR 10.5, p = 0.043) remained independently associated with shorter TTT. Among overt fibrotic patients, ANC > 8.8 × 109/L (HR 4.49, p = 0.004), ALC ≤ 1.43 × 109/L (HR 4.15, p = 0.003), platelet count ≤ 385 × 109/L (HR 4.68, p = 0.004) and chronic kidney disease (HR 9.07, p < 0.001) remained independently associated with shorter TTT.

CONCLUSIONS

Prognostic properties of ANC, ALC and platelet count are mutually independent and exceed those of NLR and PLR regarding thrombotic risk stratification. ALC and platelet count associate in opposite directions with thrombotic risk in prefibrotic and overt fibrotic MF patients.

Association Between Hemoglobin-Albumin-Lymphocyte-Platelet Index and Mortality in Hospitalized COVID-19 Omicron BA.2 Infected Patients

Background

The hemoglobin-albumin-lymphocyte-platelet (HALP) index is a novel biomarker reflecting systemic inflammation and nutritional status which are important for coronavirus disease 2019 (COVID-19) mortality. However, the association between HALP and mortality in patients with COVID-19 has yet to be investigated.

Methods

A cohort of COVID-19 Omicron BA.2 infected patients admitted to the Shanghai Fourth People's Hospital, School of Medicine, Tongji University from April 12, 2022 to June 17, 2022 was retrospectively analyzed. Laboratory examinations on hospital admission, including hemoglobin, albumin, and lymphocyte and platelet, were collected. The association between baseline HALP and in-hospital poor overall survival (OS) was assessed using Kaplan-Meier curves, Cox regression models, interaction, and stratified analyses.

Results

A total of 2147 patients with COVID-19 Omicron BA.2 infection were included in the final analyses, and mortality in the hospital was 2.65%. Multivariate analysis indicated that low HALP index was independently associated with in-hospital mortality of COVID-19 patients [hazard ratio (HR) = 2.08; 95% confidence interval (CI) = 1.17-3.73]. Subgroup analysis demonstrated that low HALP index was an independent risk factor for in-hospital mortality in COVID-19 patients with age ≥70 (HR = 2.22, CI = 1.18-4.15) and severe cases (HR = 2.09, CI = 1.13-3.86).

Conclusion

HALP index is independently related to in-hospital poor OS for COVID-19 Omicron BA.2 infected patients, especially for age ≥70 and severe cases. HALP index on hospital admission is a useful candidate biomarker for identifying high risk of mortality in COVID-19 Omicron BA.2 infected patients.

Investigation of Serum Albumin as a Dynamic Treatment-Specific Surrogate for Outcomes in Patients With Myelofibrosis Treated With Ruxolitinib

PURPOSE

Ruxolitinib improves splenomegaly and disease-related symptoms in most patients with myelofibrosis (MF), and it has been associated with a survival benefit in higher-risk patients with splenomegaly. Spleen volume reduction has been associated with a survival benefit in ruxolitinib-treated patients; however, its use as a surrogate is limited. We hypothesized that an anti-inflammatory response to ruxolitinib would correlate with improved patient outcomes.

METHODS

We interrogated serum albumin, an acute phase reactant and marker of nutritional status in 590 patients with MF and analyzed differential trajectories of albumin on the basis of ruxolitinib treatment. Additionally, we assessed the prognostic role of baseline albumin and change in albumin.

RESULTS

We found that serum albumin levels tend to decrease in patients with MF; however, this tendency is abrogated by ruxolitinib treatment. To that end, baseline serum albumin level correlates with overall survival (OS) in patients with MF, independent of the variables that comprise the dynamic international prognostic scoring system; however, this correlation is limited to ruxolitinib-naïve patients. In ruxolitinib-treated patients, the change in serum albumin after ruxolitinib treatment, rather than the baseline value, is associated with improved OS, a finding not seen in ruxolitinib-naïve patients.

CONCLUSION

These findings suggest that serum albumin, a ubiquitously available laboratory value, has specific relevance in patients with MF and reflects therapeutic response to ruxolitinib.

The Naples prognostic score in esophagus cancer: Prognostic and beyond

OBJECTIVES

The role of inflammation in tumor biology has been better understood over time. The utility of the Naples prognostic score (NPS), which is a novel inflammation-based marker, was shown in esophageal carcinoma (EC) patients treated with surgery. We herein presented the prognostic and predictive value of NPS in EC patients treated with upfront chemoradiotherapy (CRT).

METHODS

Adult EC patients with squamous cell carcinoma or adenocarcinoma were included. Median survival was compared by log-rank test. Cox regression analyses were performed to establish the independent prognostic effect of NPS.

RESULTS

Of 153 patients, 97 (63.4%) and 56 (36.6%) patients were treated with CRT alone and CRT followed by surgery, respectively. The median overall survival (OS) was significantly different among the Naples prognostic groups (NPG) (60+ months [CI 95%: NA], 27 months [CI 95%: 16.8-37.5], and 18.5 months [CI 95%: 15.3-30.7] for NPG 0,1, and 2, respectively; P=0.007). Surgery following CRT provided survival benefit in NPG 1 (65+ months with surgery vs. 17.3 months without surgery, P<0.001) and in NPG 2 (33 months with surgery vs. 15 months without surgery, P=0.009). Multivariate Cox regression analysis showed that the NPS is an independent prognostic marker for OS (HR is 1.28 for OS [CI 95%: 1.03-1.59], P=0.02).

CONCLUSION

NPS might be useful as a prognostic marker in also EC patients treated with upfront CRT. Patients with high NPS may have a high risk of recurrence. Surgery might be planned in EC at the diagnosis in NPG 1 and 2.

Systemic inflammatory indices for predicting prognosis of myelofibrosis

The impact of inflammatory markers such as systemic immune-inflammation (SII) index and systemic inflammation response index (SIRI) on myelofibrosis (MF) prognosis was evaluated for the first time in this study. Data from 60 patients diagnosed with MF between March 2011 and September 2022 were retrospectively analyzed. In addition to disease-related markers, the impact of SII and SIRI on prognosis was evaluated. In our study, the overall median survival (OS) was 64 months. OS was significantly shorter in patients older than 65 years, with high ferritin and lymphocyte levels, transfusion dependence at diagnosis, platelet count below 100 × 109/L, Hb level below 8 g/dl, and high risk according to the dynamic international prognostic scoring system (DIPSS)-Plus score. When these variables were included in the multivariate Cox regression model, it was found that being older than 65 years, having a high ferritin value, being at high risk according to the DIPSS-plus score and Hb values below 8 increased the risk of death. Platelet-to-lymphocyte ratio (PLR) and SII index were lower in patients with a fatal outcome. No statistically significant relationship was found between SIRI and mortality. The findings of this study showed that low PLR and high ferritin were associated with poor prognosis in MF. Elevated SII and SIRI, evaluated for the first time in patients with myelofibrosis, did not predict prognosis. Since non-inflammatory variables play a role in the pathogenesis of MF, bone marrow indicators and systemic inflammation indicators derived from hematologic parameters may not be accurate.

CRP/Albumin Ratio and Glasgow Prognostic Score Provide Prognostic Information in Myelofibrosis Independently of MIPSS70-A Retrospective Study

In myelofibrosis, the C-reactive protein (CRP)/albumin ratio (CAR) and the Glasgow Prognostic Score (GPS) add prognostic information independently of the Dynamic International Prognostic Scoring System (DIPSS). Their prognostic impact, if molecular aberrations are considered, is currently unknown. We performed a retrospective chart review of 108 MF patients (prefibrotic MF n = 30; primary MF n = 56; secondary MF n = 22; median follow-up 42 months). In MF, both a CAR > 0.347 and a GPS > 0 were associated with a shorter median overall survival (21 [95% CI 0-62] vs. 80 months [95% CI 57-103], p < 0.001 and 32 [95% CI 1-63] vs. 89 months [95% CI 65-113], p < 0.001). Both parameters retained their prognostic value after inclusion into a bivariate Cox regression model together with the dichotomized Mutation-Enhanced International Prognostic Scoring System (MIPSS)-70: CAR > 0.374 HR 3.53 [95% CI 1.36-9.17], p = 0.0095 and GPS > 0 HR 4.63 [95% CI 1.76-12.1], p = 0.0019. An analysis of serum samples from an independent cohort revealed a correlation of CRP with levels of interleukin-1β and albumin with TNF-α, and demonstrated that CRP was correlated to the variant allele frequency of the driver mutation, but not albumin. Albumin and CRP as parameters readily available in clinical routine at low costs deserve further evaluation as prognostic markers in MF, ideally by analyzing data from prospective and multi-institutional registries. Since both albumin and CRP levels reflect different aspects of MF-associated inflammation and metabolic changes, our study further highlights that combining both parameters seems potentially useful to improve prognostication in MF.

Prognostic Role of Cell Blood Count in Chronic Myeloid Neoplasm and Acute Myeloid Leukemia and Its Possible Implications in Hematopoietic Stem Cell Transplantation

Numerous prognostic indexes have been developed in hematological diseases based on patient characteristics and genetic or molecular assessment. However, less attention was paid to more accessible parameters, such as neutrophils, lymphocytes, monocytes, and platelet counts. Although many studies have defined the role of neutrophil-to-lymphocyte or platelet-to-lymphocyte in lymphoid malignancies, few applications exist for myeloid neoplasm or hematopoietic stem cell transplantation procedures. In this review, we synthesized literature data on the prognostic value of count blood cells in myeloid malignancies and hematopoietic stem cell transplantation in the context of classical prognostic factors and clinical outcomes.

Controlling Nutritional Status (CONUT) score is a prognostic marker for laryngeal cancer patients with curative resection

BACKGROUND

To investigate the prognostic value of pre-treatment Controlling Nutritional Status (CONUT) score in laryngeal cancer.

METHODS

Preoperative CONUT score was retrospectively calculated in 154 laryngeal cancer patients who underwent curative resection in our hospital from 2013 to 2016. The associations of CONUT with clinicopathological factors and survival were evaluated. The efficacy of CONUT score to predict prognosis was evaluated.

RESULTS

The CONUT score was associated with body mass index (p = 0.033), neutrophil (p = 0.011), tumor size (p = 0.017), pTNM stage (p = 0.001), adjuvant radiotherapy (p < 0.001), negative pathologic factors (p < 0.001), and larynx preservation (p < 0.001). Patients with a higher CONUT score had worse overall survival (hazard ratio: 1.94, 95% confidence interval [CI]: 1.13-3.72, p = 0.039) and disease-free survival (hazard ratio: 2.16, 95% CI: 1.19-3.90, p = 0.011). The area under the curve of CONUT score (0.728) was higher than Preoperative Nutritional Index (0.72), platelet-to-lymphocyte ratio (0.675), and neutrophil-to-lymphocyte ratio (0.687).

CONCLUSION

The CONUT score can be useful for predicting survival in laryngeal cancer patients after curative resection.

HALP score and GNRI: Simple and easily accessible indexes for predicting prognosis in advanced stage NSCLC patients. The İzmir oncology group (IZOG) study

Objective

The Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) Score and the Geriatric Nutrition Risk Index (GNRI) are used as prognostic factors in different types of cancers. In this study we analyzed the prognostic value of the HALP Score and the GNRI calculated prior to first-line treatment in patients diagnosed with de novo metastatic non-small cell lung cancer (mNSCLC).

Materials and methods

De novo mNSCLC patients were retrospectively evaluated from January 2016 to December 2019. Patients with Driver’s mutation, severe comorbidities, active infection, or insufficient organ function, and those receiving anti-inflammatory treatment were excluded from the study. Optimal cut-off points for the HALP score and the GNRI were calculated with the receiver operating characteristic (ROC) curve analysis. Predictive factors for overall survival (OS) were assessed with univariate and multivariate Cox proportional hazard analyses, and OS was studied with the Kaplan–Meier analysis.

Results

The study included 401 patients in total. In the ROC curve analysis, the cut-off points were found 23.24 (AUC = 0.928; 95% CI: 0.901–0.955, p &lt; 0.001) for HALP, and 53.60 (AUC = 0.932; 95% CI: 0.908–0.955, p &lt; 0.001) for GNRI. Groups with lower HALP scores and lower GNRI had significantly shorter OS compared to those with higher HALP scores and GNRIs. Univariate analysis showed that male gender, smoking, high ECOG score, low HALP score and low GNRI were associated with worse survival rates. Multivariate analysis showed that low HALP score (HR = 2.988, 95% CI: 2.065–4.324, p &lt; 0.001); low GNRI score (HR = 2.901, 95% CI: 2.045–4.114, p &lt; 0.001) and smoking history (HR = 1.447, 95% CI: 1.046–2.001, p = 0.025) were independent factors associated with worse OS rates.

Conclusion

Our study showed the HALP score and the GNRI to be of prognostic value as simple, cost-effective, and useful markers that predict OS in de novo mNSCLC patients.

GNRI And Conut Scores: Simple Predictors of Sarcopenia in Metastatic Colorectal Cancer Patients

OBJECTIVE

To evaluate the correlation between sarcopenia and inflammation- and nutrition-based markers in metastatic colorectal cancer (mCRC) patients.

MATERIALS AND METHODS

Age, body mass index (BMI), neutrophil/lymphocyte ratio (NLR), modified Glasgow prognostic score (mGPS), prognostic nutrition index (PNI), cachexia index (CIn), skeletal muscle index (SMI), controlling nutritional status (CONUT) score, and geriatric nutritional risk index (GNRI) were evaluated in 185 patients. Ideal cut-off values for the GNRI score were determined with the ROC curve analysis, and the patients were divided into two groups as low and high GNRI. Sarcopenia was diagnosed using CT scanning, the gold standard method. Univariate and multivariate Cox proportional hazard analyses were done based on the above-listed parameters to assess the correlation between sarcopenia and changes in immuno-nutrition and inflammatory response. Kaplan-Meier analysis was also done to evaluate survival.

RESULTS

Univariate analysis of the 185 patients based on the EGWSOP 2018 threshold values showed correlation between the presence of sarcopenia and male gender, diagnosed colon cancer, history of metastasectomy, BMI < 24, high mGPS score, PNI score ≥ 45, high CONUT score, and low GNRI score (p < 0.05). In multivariate analysis, low GNRI (HR: 2.40; 95% CI: 1.03-5.544; p = 0.040), and high-CONUT scores (HR: 2.01; 95% CI: 1.06-3.73; p = 0.029) were identified as independent prognostic factors for the presence of sarcopenia.

CONCLUSION

GNRI and CONUT scores are elementary and practical predictors for sarcopenia, a condition which is associated with poor outcomes in mCRC patients.

Clinical and prognostic significance of C-reactive protein to albumin ratio in hospitalized coronavirus disease 2019 (COVID-19) patients : Data on 2309 patients from a tertiary center and validation in an independent cohort

C‑reactive protein (CRP) and albumin are inflammation sensitive parameters that are regulated by interleukin‑6 inflammatory pathways. The CRP to albumin ratio (CAR) integrates these two into a potent clinical parameter whose clinical and prognostic association in the context of coronavirus disease 2019 (COVID-19) have not been well defined. We aimed to investigate the clinical and prognostic significance of CAR in the context of COVID-19 infection.We retrospectively analyzed 2309 consecutive COVID-19 patients hospitalized at a tertiary level hospital in the period from March 2020 to March 2021 who had baseline data for a CAR assessment. Findings were validated in an independent cohort of 1155 patients hospitalized from March 2021 to June 2021.The majority of patients (85.8%) had severe or critical COVID-19 on admission. Median CRP, albumin and CAR levels were 91 mg/L, 32 g/L and 2.92, respectively. Higher CAR was associated with a tendency for respiratory deterioration during hospitalization, increased requirement of high-flow oxygen treatment and mechanical ventilation, higher occurrence of bacteriemia, higher occurrence of deep venous thrombosis, lower occurrence of myocardial infarction, higher 30-day mortality and higher postdischarge mortality rates. We defined and validated four CAR prognostic categories (< 1.0, 1.0-2.9, 3.0-5.9 and ≥ 6.0) with distinct 30-day survival. In the series of multivariate Cox regression models we could demonstrate robust prognostic properties of CAR that was associated with inferior 30-day survival independently of COVID-19 severity, age and comorbidities and additionally independently of COVID-19 severity, CURB-65 and VACO index in both development and validation cohorts.The CAR seems to have a good potential to improve prognostication of hospitalized COVID-19 patients.

Controlling Nutritional Status (CONUT) Score Is a Prognostic Factor for Patients with Gastric Cancer Treated by Perioperative FLOT

PURPOSE

The aim of this study was to show that the Controlling Nutritional Status (CONUT) score has predictive value in gastric cancer (GC) patients treated with perioperative fluorouracil, leucovorin, oxaliplatin, or docetaxel (FLOT).

METHODS

A total of 161 GC patients treated with perioperative FLOT in our center were included in the study. The ideal cutoff values for the CONUT score were obtained using the receiver operating characteristic (ROC) curve analysis, and the patients were divided into low (≤3) and high (> 3) CONUT groups. The associations of CONUT with clinicopathological factors and survival were evaluated retrospectively.

RESULTS

The median follow-up time was 11.2 months (2.3-32.3 months). The median overall survival (OS) for the entire population was 14.7 months (95% CI 13.5-15.9 months). Median OS was not reached in the low-CONUT group, but it was 14.2 months (95% CI 12.6-15.9) in the high-CONUT group and the difference was statistically significant (p = 0.002). The univariate Cox proportional hazards model revealed that OS was significantly associated with Eastern Cooperative Oncology Group (ECOG) status (p < 0.001), T4b stage (p 0.03), modified Glasgow Prognostic Scores (mGPS) (p 0.005), prognostic index (PI) (p 0.011), prognostic nutritional index (PNI) (p < 0.001), CONUT score (p 0.003), and mucinous histology (p 0.004). In multivariate analysis, ECOG performance status (p 0.029), PNI (p 0.001), CONUT score (p 0.040), and mucinous histology (p 0.001) were still identified as independent prognostic factors for OS.

CONCLUSIONS

Our study demonstrated the prognostic significance of the CONUT score in GC patients treated with perioperative FLOT.

Prognostic Significance of Pretreatment Prognostic Nutritional Index (PNI) in Patients with Nasopharyngeal Carcinoma: A Meta-Analysis

OBJECTIVE

Previous studies have investigated the pretreatment prognostic nutritional index (PNI) as a prognostic factor in patients with nasopharyngeal carcinoma (NPC); however, the results remained inconsistent. We aimed to assess the prognostic value of PNI in patients with NPC through conducting meta-analysis. Methods: Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated for low PNI of overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS), loco-regional recurrence-free survival (LRFS), and cancer-specific survival (CSS). Results: Totally, eight studies involving 4299 patients were included in this meta-analysis. A low pretreatment PNI was associated with poor OS (HR = 1.86, 95% CI = 1.55-2.33, P < 0.001), DMFS (HR = 2.03, 95% CI = 1.69-2.44, P < 0.001), PFS (HR = 1.57, 95% CI = 1.31-1.90, P < 0.001), and CSS (HR = 2.29, 95% CI = 1.54-3.42, P < 0.001). The subgroup analysis showed that low PNI remained a significant factor for poor OS, DMFS, and PFS irrespective of treatment, country, and cutoff value of PNI. In addition, low PNI was correlated to female gender (OR = 1.35, 95% CI = 1.12-1.62, P = 0.002), older age (OR = 1.75, 95% CI = 1.17-2.62, P = 0.007), and T3-T4 stage (OR = 1.27, 95% CI = 1.06-1.53, P = 0.011). Conclusions: A low PNI was associated with poor survival outcomes in patients with NPC. Moreover, PNI could serve as an index to help guide clinical management for older patients.

C reactive protein to albumin ratio as prognostic marker in primary and secondary myelofibrosis

We retrospectively investigated C reactive protein to albumin ratio (CAR) in a cohort of 142 patients with myelofibrosis [101 primary (PMF); 41 secondary (SMF)] and compared it to hematological and clinical parameters. Among other associations, higher CAR was significantly associated with higher grade of bone marrow fibrosis, lower frequency of Calreticulin (CALR) mutations, presence of constitutional symptoms, massive splenomegaly, transfusion dependency, blast phase disease, lower hemoglobin, lower platelets, higher ferritin and higher lactate dehydrogenase (LDH) (p < .05 for all analyses). Higher CAR was able to predict inferior survival in PMF independently of DIPSS [hazard ratio (HR)=2.17; p = .015 for high CAR and HR = 2.05; p < .001 for DIPSS] and in SMF independently of Mysec-PM (HR = 6.48; p = .022 for high CAR and HR = 2.63; p = .013 for Mysec-PM) demonstrating its good prognostic potential. CAR seems to be an independent and prognostically relevant parameter, both in PMF and SMF, and might aid in timely recognition of most vulnerable patients.

Modified controlling nutritional status score: A refined prognostic indicator depending on the stage of gastric cancer

BACKGROUND

The role of controlling nutritional status (CONUT) score in predicting cancer survival remains uncertain. This study aimed to investigate the predictive value of the CONUT score and to develop a more appropriate scoring system beyond CONUT for gastric cancer.

METHODS

We retrospectively reviewed 1307 patients who underwent curative gastrectomy between 2009 and 2015. The CONUT and three modified scores with modified lipid components (L-CONUT: albumin/total lymphocyte count [TLC]/low density lipoprotein, H-CONUT: albumin/TLC/high density lipoprotein, and T-CONUT: albumin/TLC/triglyceride) were calculated. The predictive value of each scoring system on long-term survival was assessed.

RESULTS

The values of the four nutritional scores were categorized into four groups (normal, light, moderate, and severe). The CONUT (P < 0.001), L-CONUT (P < 0.001), H-CONUT (P < 0.001), and T-CONUT (P < 0.001) scores showed significant differences in overall survival in between groups. Survival analysis according to the pathological stage showed that advanced age, Eastern Cooperative Oncology Group performance status, male sex, and moderate H-CONUT score (HR, 3.970; 95% CI, 1.826-8.633; P = 0.001) were independent worse prognostic factors for overall survival in the stage I group. In the stage II group, light CONUT score (HR, 2.230; 95% CI, 1.067-4.664; P = 0.033) and moderate CONUT score (HR, 5.077; 95% CI, 1.647-15.650; P = 0.005) were significantly associated with poor prognosis. In the stage III group, no scoring system showed significant results.

CONCLUSION

In advanced gastric cancer (beyond stage II), the prognostic impact of the nutritional scoring system was uncertain. However, the H-CONUT score is a promising indicator of prognosis in stage I, and the CONUT score is useful for predicting long-term survival in stage II gastric cancer.

Neutral effect of Glioma-associated oncogene-1 expression on survival in myelofibrosis

This study retrospectively analyzed glioma-associated oncogene 1 (GLI‑1) mRNA expression in unfractionated bone marrow aspirates of 32 patients with myelofibrosis and 16 controls. It was found that GLI‑1 expression did not significantly differ between primary, secondary myelofibrosis and controls (median difference in threshold cycles ∆CT 7.2, 7.3 and 6.9, respectively; P = 0.864), as well as that survival curves of myelofibrosis patients with higher/lower GLI‑1 expression showed multiple overlaps and overall comparable course (P = 0.651). The results suggest that general upregulation of GLI‑1 does not seem to be a feature of the disease and are in line with modest biological and clinical effects observed with inhibitors of Hedgehog signaling pathway in patients with myelofibrosis.

Ruxolitinib binding to human serum albumin: bioinformatics, biochemical and functional characterization in JAK2V617F+ cell models

Ruxolitinib is a type I JAK inhibitor approved by FDA for targeted therapy of Philadelphia-negative myeloproliferative neoplasms (MPNs), all characterized by mutations activating the JAK2/STAT signaling pathway. Treatment with ruxolitinib improves constitutional symptoms and splenomegaly. However, patients can become resistant to treatment and chronic therapy has only a mild effect on molecular/pathologic remissions. Drugs interaction with plasma proteins, i.e. human serum albumin (HSA), is an important factor affecting the intensity and duration of their pharmacological actions. Here, the ruxolitinib recognition by the fatty acid binding sites (FAs) 1, 6, 7, and 9 of HSA has been investigated from the bioinformatics, biochemical and/or biological viewpoints. Docking simulations indicate that ruxolitinib binds to multiple sites of HSA. Ruxolitinib binds to the FA1 and FA7 sites of HSA with high affinity (K_r = 3.1 μM and 4.6 μM, respectively, at pH 7.3 and 37.0 °C). Moreover, HSA selectively blocks, in a dose dependent manner, the cytotoxic activity of ruxolitinib in JAK2V617F⁺ cellular models for MPN, in vitro. Furthermore this event is accompanied by changes in the cell cycle, p27^Kip1 and cyclin D3 levels, and JAK/STAT signaling. Given the high plasma concentration of HSA, ruxolitinib trapping may be relevant in vivo.

The prognostic value of pre-treatment prognostic nutritional index in esophageal squamous cell carcinoma: A meta-analysis

BACKGROUND

Prognostic nutritional index (PNI) is an easily obtained index inflecting both one's nutritional and inflammatory status. Its clinical role in esophageal squamous cell carcinoma (ESCC) remains still in debate. The aim of this meta-analysis was to assess the prognostic value and the clinical-pathological features of pre-treatment PNI in ESCC patients.

METHODS

A comprehensive search of online databases (PubMed, Embase, Web of Science) was performed. Studies explored the relationship between pre-treatment PNI and long-term survival of ESCC patients were regarded eligible for this meta-analysis. Outcomes were extracted and synthesized. Hazard ratio (HR) and relative ratio (RR) with 95% confidence interval (CI) were used to evaluate the prognostic value of PNI on long-term survival and association with clinical-pathological features, respectively. The heterogeneity levels and publication bias between studies were also estimated.

RESULTS

Nine observational studies involving 2276 patients were considered eligible for this meta-analysis. The pooled results showed that low PNI score was significantly correlated with poorer overall survival (OS) of esophageal cancer (pooled HR = 1.418 95%CI: 1.200-1.676, P = .000), poorer recurrence free survival (HR = 1.880 95%CI: 1.207-2.929, P = .005) but not cancer specific survival (CSS) (HR = 1.948 95%CI: 0.544-6.977, P = .306). The PNI value was not related with patient age, sex, depth of tumor invasion, nodular metastasis, and differential grade but the TNM stage (III/IV vs 0/I/II, RR = 1.276, 95% CI 1.146-1.420).

CONCLUSIONS

Low pre-treatment PNI was significantly related with OS and recurrence free survival but not CSS for ESCC. PNI was a reliable prognostic factor of ESCC, and higher stage ESCC have higher incidence of low PNI.

Development of a prognostically relevant cachexia index in primary myelofibrosis using serum albumin and cholesterol levels

Serum albumin and cholesterol levels predict survival in primary myelofibrosis, independent of each other and contemporary risk models. The cachexia index, determined by serum albumin and cholesterol levels, might further refine current prognostic models in myelofibrosis.

Controlling Nutritional Status (CONUT) as a prognostic immunonutritional biomarker for gastric cancer after curative gastrectomy: a propensity score-matched analysis

BACKGROUND

In clinical practice, it is not unusual to treat oncologic patients whose tumor markers are within normal range, even with advanced cancer. The Controlling Nutritional Status (CONUT) score could provide a useful nutritional and immunological prognostic biomarker for cancer patients. In this study, we assessed the prognostic value of the CONUT score for patients with gastric cancer, including a subgroup analysis with stratification based on serum carcinoembryonic antigen (CEA) level.

METHODS

We retrospectively reviewed the medical records of 368 consecutive patients who underwent curative laparoscopy-assisted gastrectomy. The prognostic value of the CONUT score was compared between patients with a low (≤ 2) and high (≥ 3) score, with propensity score matching (PSM) used to control for biasing covariates (Depth of tumor, Lymph node metastasis, pathological TNM (pTNM) stage).

RESULTS

Overall survival (OS) among all patients was independently predicted by the tumor stage (hazard ratio (HR): 2.231, p = 0.001), the CONUT score (HR: 2.254, p = 0.001), and serum CEA level (HR: 1.821, p = 0.025). Among patients with a normal preoperative serum CEA level, tumor stage (HR: 2.350, p = 0.007), and the CONUT score (HR: 1.990, p = 0.028) were independent prognostic factors of OS. In the high serum CEA level group, tumor size (HR: 2.930, p = 0.015) and the CONUT score (HR: 3.707, p = 0.004) were independent prognostic factors of OS.

CONCLUSIONS

It is advantageous to use both CEA level and the CONUT score to assess the prognosis of patients with gastric cancer, which reflect both tumor-related factors and host-related factors, respectively.

Prognostic implications of low transferrin saturation in patients with primary myelofibrosis

OBJECTIVES

Transferrin saturation (TSAT) 20% or less is considered to represent functional iron deficiency in the context of malignant disease, phenomenon mediated through inflammatory changes of iron homeostasis. We aimed to investigate clinical and prognostic significance of low TSAT in patients with primary (PMF) and secondary myelofibrosis (SMF), malignant diseases characterized by strong inflammatory milieu.

METHODS

We retrospectively analyzed 87 patients with myelofibrosis and compared TSAT with disease specific parameters.

RESULTS

One-third of patients had TSAT ≤20%. Lower TSAT was significantly associated with Janus-kinase-2 (JAK2) mutation (P = 0.007), transfusion independency (P = 0.003), higher platelets (P = 0.004), lower mean-corpuscular-volume (P < 0.001), lower ferritin (P < 0.001), higher absolute-neutrophil-count (P = 0.027), lower absolute-lymphocyte-count (P = 0.041) and lower albumin (P = 0.018). PMF patients presenting with low TSAT (≤20%) experienced significantly shorter overall-survival (OS) (HR = 2.43; P = 0.017), whereas TSAT did not affect OS of SMF patients (HR = 1.48; P = 0.623). Low TSAT remained significantly associated with inferior OS in PMF in a series of multivariate Cox regression models comparing its properties to anemia, transfusion dependency, ferritin and Dynamic-International-Prognostic-System (DIPSS).

CONCLUSIONS

Low TSAT has detrimental effect on survival of PMF patients. This effect is independent of anemia and of ferritin levels that seem to be better at representing iron overload in PMF patients.
