Background: Red blood cell distribution width is a measure of the variation of erythrocyte volume and has recently been advocated as a prognostic tool in neoplastic and non-neoplastic diseases. We studied the prognostic role of preoperative red blood cell distribution width (RDW) in resected pN1 lung adenocarcinoma patients. Methods: Sixty-seven consecutive pN1 lung adenocarcinoma patients operated in the last two years were retrospectively evaluated in the present study. Age, sex, smoking status, type of surgical resection, neoadjuvant and adjuvant treatments, pathological stage, T and N status, tumor size, preoperative hemoglobin (Hb) and RDW, preoperative neutrophils, lymphocytes, and their ratio were collected for each patient. Outpatient follow-up was performed and date of relapse was recorded. Results: There were 24 females (35.8%). Twenty-eight patients (41.8%) belonged to stage 3A and thirty-nine patients (58.2%) to stage 2B. Mean preoperative RDW % was 14.1 (IQR: 12.9–14.8). Univariate analysis disclosed preoperative RDW as strictly related to disease-free survival (p = 0.02), which was confirmed in the exploratory multivariable analysis (p = 0.003). Conclusions: Pre-operative RDW is an effective prognostic factor of disease-free survival in resected pN1 lung adenocarcinoma; it could therefore be considered as a further tool for planning postoperative adjuvant treatments and setting up an adequate follow-up program.

Background: The ratio of hemoglobin to red cell distribution width (HRR) has been described as an effective prognostic factor in several types of cancer. The aim of this study was to investigate the prognostic role of preoperative HRR in resected-lung-adenocarcinoma patients. Methods: We enrolled 342 consecutive patients. Age, sex, surgical resection, adjuvant treatments, pathological stage, preoperative hemoglobin, red cell distribution width, and their ratio were recorded for each patient. Results: Mean age was 66 years (SD: 9.0). There were 163 females (47.1%); 169 patients (49.4%) had tumors at stage I, 71 (20.8%) at stage II, and 102 (29.8%) at stage III. In total, 318 patients (93.0%) underwent lobectomy, and 24 (7.0%) pneumonectomy. Disease-free survival multivariable analysis disclosed an increased hazard ratio (HR) of relapse for preoperative HRR lower than 1.01 (HR = 2.20, 95%CI: (1.30–3.72), p = 0.004), as well as for N1 single-node (HR = 2.55, 95%CI: (1.33–4.90), p = 0.005) and multiple-level lymph node involvement compared to N0 for both N1 (HR = 9.16, 95%CI:(3.65–23.0), p < 0.001) and N2 (HR = 10.5, 95%CI:(3.44–32.2, p < 0.001). Conclusion: Pre-operative HRR is an effective prognostic factor of disease-free survival in resected-lung-adenocarcinoma patients, together with the level of pathologic node involvement.

Összefoglaló. Bevezetés: A krónikus lymphoid leukémia kezelésében jelentős előrelépést eredményezett az ibrutinibterápia bevezetése. A gyógyszer első vonalbeli és többed vonalbeli kezelése is magas remissziós arányt eredményezett, bár a terápia korai bevezetése és a kedvező genetikai eltérések esetén az eredmények jobbak. A progressziómentes túlélést befolyásoló egyéb tényezőkről azonban még kevés adat áll rendelkezésre. Célkitűzés: Krónikus lymphoid leukémiás betegek ibrutinibkezelése során a teljes hematológiai remisszió elérését és a progressziómentes túlélés időtartamát befolyásoló tényezők vizsgálata. Betegek és módszer: 47 krónikus lymphoid leukémiás beteg (életkor: 39–84 év, férfi 27, nő 20, követési idő 5–58 hónap, medián 15 hónap) klinikai és laboratóriumi adatainak retrospektív elemzése. Eredmények: A teljes hematológiai remisszió elérése független volt a betegek nemétől, életkorától, a betegség stádiumától, az immunglobulin gén nehézlánc-variábilis régió státuszától, a genetikai aberrációktól, az abszolút neutrophilszámtól, az abszolút monocytaszámtól és a vörösvértestnagyság-eloszlási görbe szélességétől. A progressziómentes túlélést a komplett remisszió elérése (p = 0,00073) és a magasabb abszolút neutrophilszám (<4 G/l vs. ≥4 G/l, p = 0,022) befolyásolta szignifikánsan, a vörösvértestnagyság-eloszlási görbe szélességértékével való összefüggés pedig statisztikailag határértéken volt (p = 0,065). A Cox-féle regressziós elemzésbe bevont változók közül csak a teljes hematológiai remisszió elérése mutatott szignifikáns hatást a progressziómentes túlélésre (p = 0,0147). Következtetések: A teljes hematológiai remisszió elérése az egyéb vizsgált tényezőktől független, szignifikáns hatással bír a betegek progressziómentes túlélésére. Az abszolút neutrophilszám és a vörösvértestnagyság-eloszlási görbe szélessége szintén hasznos kiegészítő prognosztikus marker lehet. Az elemzett esetek száma még alacsony a komolyabb következtetések levonására, azonban így is elmondható, hogy az eredmények egy része már a szakirodalom korábbi eredményeit tükrözi. Summary. Introduction: The introduction of ibrutinib therapy has led to significant advances in the treatment of chronic lymphocytic leukemia. Both first-line and multiple-lines treatments of the drug resulted in high remission rates, although results were better with early initiation of therapy and favorable genetic abnormalities. However, little data are available on other factors influencing progression-free survival. Objective: To investigate factors influencing the achievement of complete hematological remission and progression-free survival with ibrutinib treatment in patients with chronic lymphocytic leukemia. Patients and metods: Retrospective analysis of clinical and laboratory data from 47 chronic lymphoid leukemia patients (age: 39–84 years, male 27, female 20, follow-up 5–58 months, median 15 months). Results: Achieving complete hematologic remission was independent of patient gender, age, disease stage, immunoglobulin heavy chain variable region status, genetic aberrations, absolute neutrophil count, absolute monocyte count, and red blood cell distribution width. Progression-free survival was significantly affected by complete remission (p = 0.00073), and higher absolute neutrophil counts (<4 G/l vs. ≥ 4 G/l, p = 0.022), the red blood cell distribution width was statistically less significant (p = 0.065). Of the variables included in the Cox regression analysis, only the achievement of complete hematologic remission had a significant effect on progression-free survival (p = 0.0147). Conclusions: Achieving complete hematologic remission, independent of the other factors studied, has a significant effect on patients’ progression-free survival. Absolute neutrophil count and red blood cell distribution width can also be a useful additional prognostic marker. The number of analyzed cases is still low to draw more serious conclusions, but it can still be said that some of the results already reflect previous results in the literature.

Summary Background: Universally accepted and validated instruments for predicting the outcome of patients presenting to the emergency department (ED) with severe dyspnoea do not exist so far, nor are they regularly used by the emergency physicians. This study hence aimed to establish whether red blood cell distribution width (RDW) may be a predictive parameter of 1-year mortality in a population of patients admitted to the ED with severe dyspnoea attributable to different underlying disorders. Methods: We retrospectively evaluated all the patients undergoing arterial blood gas analysis for severe dyspnoea (irrespective of the cause) during admission to ED of University Hospital of Verona from September 1, 2014 to November 31, 2014. Results: The final study population consisted of 287 patients for whom complete clinical and laboratory information was available. Overall, 36 patients (12.5%) died after a 1-year follow-up. The RDW value was found to be considerably increased in patients who deceased during the follow-up compared to those who survived (17.2% versus 14.8%; p<0.001). In both univariate and multivariate analyses, the RDW value was found to be a significant predictor of 1-year mortality. In particular, patients with RDW ≥ 15.0% displayed a 72% increased risk of 1-year mortality after multiple adjustments. Conclusions: The measurement of RDW, a very simple and inexpensive laboratory parameter, may represent an important factor for predicting medium-term mortality in patients presenting to the ED with severe dyspnoea.

The identification of biomarkers predicting disease severity and outcomes is the focus of intense research in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 infection). Ideally, such biomarkers should be easily derivable from routine tests. We conducted a systematic review and meta-analysis of the predictive role of the red blood cell distribution width (RDW), a routine hematological test, in patients with SARS-CoV-2 infection. We searched the electronic databases PubMed, Web of Science and Scopus, from January 2020 to November 2020, for studies reporting data on the RDW and coronavirus disease 2019 (COVID-19) severity, defined as severe illness or admission to the intensive care unit (ICU), and mortality. Eleven studies in 4901 COVID-19 patients were selected for the meta-analysis. Pooled results showed that the RDW values were significantly higher in patients with severe disease and non-survivors (standard mean difference, SMD = 0.56, 95% CI 0.31 to 0.81, p < 0.001). Heterogeneity between studies was extreme (I2 = 80.6%; p < 0.001). In sensitivity analysis, the effect size was not modified when each study was in turn removed (effect size range, between 0.47 and 0.63). The Begg’s (p = 0.53) and Egger’s tests (p = 0.52) showed no evidence of publication bias. No significant correlations were observed between SMD and age, gender, whole blood count, end point, study geographic area, or design. Our meta-analysis showed that higher RDW values are significantly associated with COVID-19 severity and mortality. This routine parameter might assist with early risk stratification in patients with SARS-CoV-2 infection.
