Increased Erythrocyte Sedimentation Rate in Dogs: Frequency in Routine Clinical Practice and Association with Hematological Changes

(1) Background: the erythrocyte sedimentation rate (ESR) has been reported to increase in some infectious or inflammatory diseases in dogs, but no information on the frequency of increases in a routine clinical setting exists. The aim of this study was to assess the frequency of an increased ESR in dogs and to investigate its possible association with hematologic changes; (2) Methods: A total of 295 EDTA blood samples were randomly selected from the routine caseload of the Veterinary Teaching Hospital. Samples were grouped in controls and in pathologic groups based on the clinical presentation. A routine hemogram was performed, then the ESR was measured using the instrument MINI-PET; (3) Results: compared with controls, the ESR was significantly higher in all the pathologic groups, except for the hematological disorders group. The highest ESR was found in samples from dogs with chronic kidney disease or inflammation, followed by those from dogs with mild chronic disorders, severe/acute diseases, tumors and urinary disorders. The ESR negatively correlated with hematocrit and positively with neutrophil counts. (4) Conclusions: The ESR increases more frequently in dogs with clinically evident inflammation or CKD, but also in several other conditions, likely as a consequence of anemia and acute phase response.

The Role of Erythrocyte Sedimentation Rate (ESR) in Myeloproliferative and Lymphoproliferative Diseases: Comparison between DIESSE CUBE 30 TOUCH and Alifax Test 1

(1) Background: The erythrocyte sedimentation rate (ESR) is widely diffused in hematology laboratories to monitor inflammatory statuses, response to therapies (such as antibiotics), and oncologic diseases. However, ESR is not a specific diagnostic marker but needs to be contextualized and compared with clinical and other laboratory findings. This study aimed to investigate the performance of two automated instruments, namely the DIESSE CUBE 30 TOUCH (DIESSE, Siena, Italy) and the Alifax Test 1 (Alifax Srl, Polverara, Italy), in comparison with the gold standard, the Westergren method, in lymphoproliferative and myeloproliferative patients. (2) Methods: 97 EDTA samples were selected from the hematology department of Roma Tor Vergata Hospital and analyzed. Statistical analysis was applied. (3) A good correlation between CUBE 30 TOUCH and the gold standard was observed in the overall sample (R2 = 0.90), as well as in patients with lymphoproliferative diseases (R2 = 0.90) and myeloproliferative diseases (R2 = 0.90). The correlation between Test 1 and the gold standard was observed in the overall sample (R2 = 0.68), as well as in patients with lymphoproliferative diseases (R2 = 0.79) and myeloproliferative diseases (R2 = 0.53). (4) Conclusions: The CUBE 30 TOUCH appears to be a more trustworthy tool for evaluating ESR in these pathologies.

Surgical Outcome and Prognosis of Patients with Spinal Metastasis from Esophageal Cancer: The Experience from a Single Center

BACKGROUND

The spine is one of the common sites of esophageal cancer metastasis, with a worse prognosis than that of metastasis occurring in other sites. However, the exact mechanism underlying metastatic spinal esophageal cancer (MSEC) is poorly understood possibly due to the short survival time of patients. The aim of this study was to evaluate surgical outcomes and factors affecting the prognosis of patients with MSEC.

METHODS

Enrolled in this retrospective study were 20 consecutive patients who received surgical treatment for MSEC in our hospital from 2013 to 2020. The impact of surgery on patient's quality of life was assessed by visual analog scale score and American Spinal Injury Association grade. Prognostic variables relative to traditional clinical parameters and inflammation and nutrition indicators were identified by univariate and multivariate analyses.

RESULTS

The median survival time of patients with MSEC was 6 months, with a one-year survival rate of 20%. Pain relief was achieved in most patients, and nerve function was recovered in part of the patients after surgery. Analysis of clinical factors showed that total tumor resection was beneficial to overall survival of patients with MSEC. Laboratory indicators of erythrocyte sedimentation rate, neutrophil/lymphocyte ratio, and platelet/lymphocyte ratio were identified as independent prognostic factors for patients with MSEC.

CONCLUSIONS

Timely surgical intervention can improve the quality of life of patients with MSEC. The preoperative erythrocyte sedimentation rate, neutrophil/lymphocyte ratio, and platelet/lymphocyte ratio could help predict the overall survival of patients with MSEC. These findings may help in decision-making for the treatment of patients with MSEC.

Establishment and Validation of a Predictive Model for Radiation-Associated Aspiration Pneumonia in Patients with Radiation-Induced Dysphagia after Nasopharyngeal Carcinoma

Introduction

Radiotherapy for patients with head and neck cancers raises their risk of aspiration pneumonia-related death. We aimed to develop and validate a model to predict radiation-associated aspiration pneumonia (RAP) among patients with dysphagia after radiotherapy for nasopharyngeal carcinoma (NPC).

Materials and Methods

A total of 453 dysphagic patients with NPC were retrospectively recruited from Sun Yat-Sen Memorial Hospital from January 2012 to January 2018. Patients were randomly divided into training cohort (n = 302) and internal validation cohort (n = 151) at a ratio of 2 : 1. The concordance index (C-index) and calibration curve were used to evaluate the accuracy and discriminative ability of this model. Moreover, decision curve analysis was performed to evaluate the net clinical benefit. The results were externally validated in 203 dysphagic patients from the First People's Hospital of Foshan.

Results

Derived from multivariable analysis of the training cohort, four independent factors were introduced to predict RAP, including Kubota water drinking test grades, the maximum radiation dose of lymph node gross tumor volume (Dmax of the GTVnd), neutrophil count, and erythrocyte sedimentation rate (ESR). The nomogram showed favorable calibration and discrimination regarding the training cohort, with a C-index of 0.749 (95% confidence interval (CI), 0.681 to 0.817), which was confirmed by the internal validation cohort (C-index 0.743; 95% CI, 0.669 to 0.818) and the external validation cohort (C-index 0.722; 95% CI, 0.606 to 0.838).

Conclusions

Our study established and validated a simple nomogram for RAP among patients with dysphagia after radiotherapy for NPC.

Prognostic Role of Systemic Inflammatory Markers in Patients Undergoing Surgical Resection for Oral Squamous Cell Carcinoma

Background: A high platelet−lymphocyte ratio (PLR) is a marker of systemic inflammation and, together with the neutrophil−lymphocyte ratio (NLR), is associated with poor outcomes in several cancers. We investigated the prognostic value of PLR and other systemic inflammatory markers, such as NLR, systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI), in oral squamous cell carcinoma (OSCC) patients undergoing surgical resection. Methods: We derived PLR, NLR, SII, and SIRI from a retrospective chart review of 269 consecutive OSCC patients. The complete blood count examined in the immediate preoperative period was used to compute PLR, NLR, SII, and SIRI. We analyzed the relationship between these systemic inflammatory markers and the clinicopathologic characteristics, disease-specific survival (DSS), and progression-free survival (PFS) of patients. Results: In the univariate analysis, high PLR and SII were significantly associated with worse DSS and PFS (all p < 0.05). In the multivariate analysis, PLR (HR 2.36, 95% CI 1.28−4.36 for DSS; HR 1.80, 95% CI 1.06−3.06 for PFS) was an independent predictor of survival outcomes. When PLR was analyzed as a continuous variable, the relationship between the outcome and preoperative PLR was not monotonically linear. In the subgroup analysis, PLR was more strongly associated with DSS and PFS in patients who were male, had stage III/IV OSCC, or had lymph node metastasis. Conclusion: Our data suggest that in OSCC patients, the pretreatment PLR is an independent predictor of DSS and PFS. The PLR is a readily available biomarker that will improve prognostication and risk stratification in OSCC.

The prognostic significance of erythrocyte sedimentation rate in COVID-19

OBJECTIVE

There are limited data about the significance of erythrocyte sedimentation rate as a single prognostic parameter for the prognosis and mortality of COVID-19. This study aimed to investigate the diagnostic utility of erythrocyte sedimentation rate as a prognostic factor for the disease severity and mortality in patients with COVID-19.

METHODS

A total of 148 consecutive patients with a confirmed diagnosis of COVID-19 and hospitalized at the intensive care unit or non-the intensive care unit were included in the study. The patients were allocated to groups as severe/critical disease versus nonsevere disease and survivors and nonsurvivors. The prognostic role and predictable values of erythrocyte sedimentation rate were analyzed.

RESULTS

Erythrocyte sedimentation rate was found to be higher among patients with severe/critical disease compared to those with nonsevere disease (p<0.001) and among nonsurvivors compared to survivors (p<0.001). The logistic regression analysis showed that erythrocyte sedimentation rate was an independent parameter for predicting disease severity and mortality. The role of erythrocyte sedimentation rate in the assessment of severity and mortality in patients with COVID-19 was analyzed using the receiver operating characteristic curve and was found to be significant in both. The analyses suggested that the optimum erythrocyte sedimentation rate cutoff point for disease severity and mortality were 52.5 mm/h with 65.5% sensitivity and 76.3% specificity and 56.5 mm/h with 66.7% sensitivity and 72.5% specificity.

CONCLUSION

Our results suggest that erythrocyte sedimentation rate was an independent prognostic factor for severity and mortality in patients with COVID-19.

An Evaluation of Inflammatory and Nutritional Status of Breast Cancer Outpatients in a Tertiary Hospital in Nigeria

AIM

To assess the relationship between nutritional status and inflammatory markers of breast cancer patients, and to identify predictors of malnutrition in these patients.

METHODS

This is a cross-sectional study of 45 patients with breast cancer assessed between January and June 2018. Nutritional status was evaluated by objective and subjective methods. The inflammatory markers and inflammation-based scores evaluated were C-reactive protein (CRP), albumin, erythrocyte sedimentation rate (ESR), Glasgow Prognostic Score (GPS), CRP/albumin ratio, and Albumin/CRP ratio.

RESULTS

A total of 45 patients were evaluated. Majority of the patients have high levels of both CRP and ESR (73.3% and 86.7% respectively). More than 70% of the patients were well nourished. There was no significant association between CRP (P = 0.067), ESR (P = 0.094) and SGA (Subjective Global Assessment) categories. Albumin (P < 0.001), Albumin/CRP ratio (P = 0.002), CRP/albumin ratio (P = < 0.001), and GPS (P < 0.001) were significantly associated with SGA categories. On multivariate analysis, albumin (P < 0.001), Albumin/CRP ratio (P = 0.004), CRP/albumin ratio (P = 0.009), GPS (P = 0.01), and ECOG (P = 0.009) were the only markers independently related to malnutrition.

CONCLUSION

The inflammation-based scores were significantly associated with malnutrition and can be used as biochemical nutritional assessment tools in cancer patients.

Oncologic safety of propeller flap and free flap in reconstruction after soft tissue sarcoma resection

BACKGROUND AND OBJECTIVES

The propeller flap is a reliable option for reconstruction after soft tissue sarcoma resection. However, some parts of the resection margin may move away from its original position during flap rotation and thus can be excluded from the clinical target volume of adjuvant radiotherapy. This study aimed to evaluate local recurrence after soft tissue sarcoma resection with propeller flap or free flap reconstruction.

METHODS

Patients who underwent resection of soft tissue sarcoma followed by a free flap or propeller flap reconstruction and adjuvant radiotherapy at a single institution were retrospectively reviewed.

RESULTS

The 1- and 3-year local control rates were 94.6% and 88.6% in the free flap group vs 90.6% and 87.5% in the propeller flap group, without statistical significance. There were no statistically significant differences in 5-year local recurrence-free survival (88.6% vs 87.5%) and disease-free survival (82.5% vs 74.8%) between the groups.

CONCLUSIONS

Although there was no significant difference in local control and disease-free survival rates between propeller flap and free flap reconstruction after soft tissue sarcoma resection, a multidisciplinary approach is needed to obtain surgical information for determining the accurate clinical target volume of adjuvant radiotherapy and the area for meticulous follow-up postoperatively.

Prognostic value of neutrophil-to-lymphocyte ratio and other inflammatory markers in patients with high-risk soft tissue sarcomas

BACKGROUND

Soft tissue sarcomas (STS) have a high risk of relapse in spite of the use of (neo)adjuvant chemotherapy. In this context, looking for new prognostic biomarkers is an interesting field of research. Our aim is to analyze the prognostic impact of neutrophil-to-lymphocyte ratio (NLR) and other serum markers in patients with STS who received chemotherapy with curative intent.

MATERIALS AND METHODS

This is a retrospective observational study. We included all patients with STS (primary tumor, local recurrence or resected metastatic disease) treated with high-dose ifosfamide and epirubicin with curative intent from January 2007 to December 2018. The pretreatment NLR and other serum markers were calculated, selecting the median as the cut-off value for the survival and multivariate analysis.

RESULTS

Seventy-nine patients were included. Median NLR, platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) were 2.83, 174.05 and 3.25, respectively. Median progression-free survival (PFS) was significantly longer in patients with low NLR [not reached (NR) vs 21, 92 months, P < 0.01]. No significant differences were found for PFS regarding PLR or LMR. For overall survival (OS), a significant survival advantage was also found for patients with low NLR (NR vs 65.45 months, P = 0.01), without differences for PLR or LMR. In multivariate analysis, NLR remains an independent prognostic factor for PFS.

CONCLUSION

In our cohort, low NLR was significantly associated with a longer PFS and OS, and is consolidated as an independent prognostic factor.

Meta-Analysis of Hematological Biomarkers as Reliable Indicators of Soft Tissue Sarcoma Prognosis

Background: Several recent studies have reported the reliable prognostic effect of hematological biomarkers in various tumors. Yet, the prognostic value of these hematological markers in soft tissue sarcoma (STS) remains inconclusive. Thus, the aim of this meta-analysis was to check the effect of hematological markers on the prognosis of STS. Methods: We systematically searched for relevant papers published before October 2019 in the PubMed and EMBASE databases. Overall survival (OS) and disease-specific survival (DSS) were the primary outcome, whereas disease-free survival was the secondary outcome. A thorough study of hazard ratios (HR) and 95% of confidence intervals (CIs) was done for determining the prognostic significance. Results: We performed 23 studies that comprised of 4,480 patients with STS. The results revealed that higher neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP), and platelet-to-lymphocyte ratio (PLR) were associated with poor OS/DFS (HR = 2.08/1.72, for NLR; HR = 1.92/1.75, for CRP, and HR = 1.86/1.61, for PLR). In contrast, a low lymphocyte-to-monocyte ratio (LMR) was relate to worse OS/DFS (HR = 2.01/1.90, for LMR). Moreover, pooled analysis illustrated that elevated NLR and CRP represents poor DSS, with HRs of 1.46 and 2.06, respectively. In addition, combined analysis revealed that higher Glasgow prognostic score (GPS) was linked to an adverse OS/DSS (HR = 2.35/2.77). Conclusion: Our meta-analysis suggested that hematological markers (NLR, CRP, PLR, LMR, and GPS) are one of the important prognostic indicators for patients affected by high-grade STS and patients with the STS being located in the extremity.
