Abstract Background The differences between the clinical characteristics and survival time in malignancy- and non-malignancy–associated secondary hemophagocytic lymphohistiocytosis (HLH) are unclear. Here, we describe the clinical characteristics, prognostic factors, and survival outcomes of malignancy-associated HLH compared to that of non-malignancy–associated HLH. Methods We retrospectively analyzed 91 pediatric patients with HLH (age < 14 years) at the Affiliated Hospital of Qingdao University Pediatric Department between January 2005 and October 2016. The patients were divided into the malignancy-associated group (n = 22) and non-malignancy–associated group (n = 69, also considered the control group). The clinical features were compared using the Mann–Whitney U and χ2 tests. The overall survival time was compared using log rank and Mann–Whitney U tests. Results Hemoglobin (HGB; p = 0.004), alanine aminotransferase (ALT; p = 0.002), and aspartate aminotransferase (AST; p = 0.001) levels in the malignancy-associated group differed from that in the non-malignancy–associated group. The mean survival times were 26.9 ± 3.82 months (malignancy-associated HLH) and 35.03 ± 2.19 months (non-malignancy–associated HLH). The overall survival time between the two groups was not statistically significantly different (p = 0.055). Univariate analysis showed that disseminated intravascular coagulation (DIC) score > 5 (p = 0.001), albumin < 25 g/L (p = 0.000), HGB < 60 g/L (p = 0.001), and platelet count (PLT) < 30 × 109/L (p = 0.042) correlated with prognosis. Multivariate Cox analysis showed that albumin < 25 g/L (p = 0.017), HGB < 60 g/L (p = 0.027), and bone marrow hemophagocytosis (p = 0.034) correlated with worse prognosis. Conclusions Patients with non-malignancy–associated HLH do not have better survival, although their prognosis is relatively better in clinical practice. A higher DIC score at diagnosis and lower albumin, HGB, and PLT levels are negative prognostic factors in malignancy-associated HLH.

Background: Pancreatic cancer is a devastating disease, being the fourth cause of cancer-related death worldwide. Several studies have investigated the use of multiple cancer biomarkers, such as C 19-9, CA 125, and CEA, as prognostic factors for overall survival in pancreatic cancer. CA 125 seems to have superior predictive utility in selected groups of PDAC patients. Material and methods: We retrospectively analyzed data collected from 129 patients admitted to our Department due to diagnosis with pancreatic cancer. Prior to the survival analysis, the preliminary assessment of pre-treatment levels of biomarkers was carried out. The overall survival time was defined as that elapsing from the admission date to the date of death. Results: The patients mean age was 62 +/- 9.5 years, while the median overall survival (OS) was 7mo 12d. As for tumor localization, most of the patients had PDAC within the head of the pancreas (n=93), followed by PDAC of the pancreatic body (n=15), pancreatic tail (n=14) and both pancreatic body and tail (n=7). Ninety-five patients had an unresectable tumor and 34 were diagnosed with a resectable tumor (tab.1). The statistically significant correlation was found for CA 125 (ρ=-0.355 p<0.001) and CA 19-9 (ρ=-0.225 p=0.012). We chose the following cut-off points: CA 125>=20 IU/mL was considered as high, and CA 19-9>=200 IU/mL as significantly elevated. In the univariate analysis in the Kaplan-Meier survival model, adjusted for age, both elevated biomarkers were statistically significant prognostic factors of OS (CA 125<20 median OS- 10mo 3d vs. CA 125>=20- 4mo 17d p=0.001) and (CA19-9<200 median OS- 8mo 3d vs. CA 19-9>=200- 4mo 20d p=0.001). Patients’ gender and, PDAC resectability and its localization were not statistically significant prognostic factors (log rank test p=0.8; p=0.108 and p=0.578 respectively). In the age-adjusted multivariate analysis, both biomarkers remained significant- CA 125>=20 (HR: 1.73 95%CI 1.27-2.58 p=0.006) CA 19-9>=200 (HR: 1.78 95%CI 1.19-2.66 p=0.005) Conclusions: Our study proves the utility of the pretreatment assessment of CA 125 because its level is tightly correlated with OS. It may be hypothesized that the pretreatment measurement of both CA 19-9 and CA 125 can provide the valuable information about patients’ prognosis.

Abstract Background. Little is known about the clinical phenotype of amyotrophic lateral sclerosis (ALS) in non-Caucasian populations. Here, we aimed to describe the clinical characteristics, prognostic factors and survival of Mexican patients with ALS. Methods. We conducted a retrospective study by reviewing the medical records of patients with ALS that attended and were regularly followed at a third level hospital in Mexico City from 2000 to 2015. We calculated absolute and relative frequencies of the clinical characteristics from all the participants. We also estimated correlation coefficients between clinical features and overall survival. Additionally, survival rates were compared for all participants grouped according to different clinical features using the Kaplan-Meier method and the log-rank test. Results. We enrolled 45 ALS patients, 53.33% had spinal-onset ALS and 46.66% presented bulbar ALS. The male/female ratio was 0.8. The mean age at onset of symptoms was 58.11 years. Mean survival time from onset was 64.73 ± 34.83 months. Cumulative survival rate after 5 years of disease onset was 44.44%. Age at onset and age at diagnosis inversely correlated with overall survival time. Also, we found that bulbar-onset, short diagnostic delay, percutaneous endoscopic gastrostomy, mechanical ventilation, and lower total cholesterol serum levels were associated with short survival. Conclusions. The clinical characteristics of Mexican ALS patients differ from the disease phenotype observed in Caucasians. Nonetheless, the predictive value of certain well-recognized prognostic factors remains consistent in our population. The current study provides relevant information for a better understanding of prognostic factors in ALS patients from Mexico and other Latin American countries.

Background: To evaluate the expression and clinicopathological significance of a disintegrin and metalloproteinases 19 (ADAM19) CUE domain containing protein 2 (CUEDC2) in extrahepatic cholangiocarcinoma (EHCC). Materials & methods: Immunostaining of ADAM19 and CUEDC2 was performed by EnVision immunohistochemistry in benign and malignant biliary tract tissues. Result: The expression of ADAM19 and CUEDC2 were significantly higher in EHCC (p < 0.05). ADAM19 expression was positive correlated with CUEDC2 expression in EHCC (p < 0.05). The overall survival time of those with positive expression of ADAM19 and CUEDC2 was lower (p < 0.001). Both positive expression of ADAM19 and CUEDC2 were independent prognostic factors in EHCC. Conclusion: ADAM19 and CUEDC2 have a positive correlation to the pathogenesis and dismal prognosis in EHCC.

The Impact

Background: Mast cell tumors (MCT) are among the most common malignant cutaneous neoplasm in dogs with variable biologic behavior and remain a therapeutic challenge in high-grade cases. Surgery remains the primary treatment for canine MCT; however, chemotherapy and radiation therapy are commonly used to treat aggressive cases. The combination of vinblastine (VBL) at a dose of 2 mg/m² and prednisone is the classically described protocol for MCT treatment. Studies have shown the safety of higher VBL doses for dogs with MCT, but there is a lack of information regarding dose intensity and outcome as a goal after chemotherapy.   This study aimed to evaluate the impact of a higher dose of VBL on MCT treatment outcome.Materials, Methods & Results: This was an observational and comparative study conducted in two different Veterinary Teaching Hospitals. Client-owned dogs with histopathological diagnosis of grade II or III MCT were selected and underwent at least four chemotherapy sessions with VBL and prednisone. The experimental group (EG) consisted of 18 dogs that received a dose of 3 mg/m² VBL treated in one institution. The control group (CG) included 31 dogs that received a dose of 2 mg/m² VBL treated at the other institution. All dogs treated in both groups had a clinical and complete blood count (CBC) evaluation performed previous the start of chemotherapy (T0) and before each weekly treatment (T1, T2, T3, and T4). After treatment, dogs in both groups were followed-up for the recurrence rate and overall survival time after diagnosis. There was no significant difference in clinical variables between EG and CG. During treatment, dogs of EG showed a significant reduction in erythrocyte, hemoglobin, and hematocrit values between T0 and T1, T2, T3, and T4 (P < 0.001). Comparatively, the CG showed significant reduction in hemoglobin (P = 0.02) and total leucocytes (P = 0.001) values in the same period. Despite these findings, these hematological parameters did not exceed the lower limit for the species in both groups. There was a higher-grade neutropenia one week after the first VBL application (T2) in both groups, with no statistical difference in neutrophil counts at T2 or during the whole treatment. There were discrete and self-limited episodes of anorexia, vomiting, and diarrhea in both groups. After chemotherapy, dogs in EG showed a significantly lower rate of recurrence than dogs in CG (P = 0.02). There was no significant difference in the overall survival time between groups.Discussion: The absence of significant differences in clinical variables (e.g. sex, age, histological grading, and tumor location) between EG and CG suggests that the groups may be similar regarding these parameters. All dogs included in this study had a recommendation for MCT post-operative chemotherapy treatment. VBL action is non-selective and anemia is not a commonly described adverse effect associated with its administration. Despite that, EG dogs exhibited a reduction in erythrocytes, hematocrit, and hemoglobin, and CG dogs in hemoglobin throughout T0 to T4. The highest number of neutropenia episodes occurred during T2, after the first VBL application in both groups with a trend of stabilization after T2, which is compatible with findings described in the literature. Any dog of EG or CG had to interrupt the treatment due to hematological or gastrointestinal toxicity or died during treatment. The role of VBL dose intensity in outcome is still debatable for dogs with MCT, once it is a multifactorial disease with variable presentation. In this study, there was no difference in overall survival time after diagnosis between groups, and EG dogs treated with a higher VBL dose showed significantly less tumor recurrence than CG.

The indoleamine 2,3-dioxygenase-(IDO-) mediated microenvironment plays an important role in tumor immune escape. However, the inhibitory effects of IDO on the CD8+tumour-infiltrating lymphocytes (CD8+TILs) in esophageal squamous cell carcinoma (ESCC) have not been clarified yet. Here, we found that the level of IDO expression in ESCC tumor specimens correlated with a reduction in the number of CD8+TILs. Patients with high IDO expression and a low number of CD8+TILs had significantly impaired overall survival time. IDO expression and functional enzyme activity in ESCC cell lines could be induced by IFNγ. When exposed to the milieu generated by IDO-expressing Eca109 cells, the CD8+TILs were suppressed in proliferation, and their cytolytic functions against target tumor cells were lost. These results suggested that impairing CD8+TIL functions by IDO expressed in ESCC possibly contributed to the finding that patients with higher IDO expression have more aggressive disease progression and shorter overall survival time.
