Lymphoma lesion detection and segmentation on whole-body FDG-PET/CT are a challenging task because of the diversity of involved nodes, organs or physiological uptakes. We sought to investigate the performances of a three-dimensional (3D) convolutional neural network (CNN) to automatically segment total metabolic tumour volume (TMTV) in large datasets of patients with diffuse large B cell lymphoma (DLBCL).
The dataset contained pre-therapy FDG-PET/CT from 733 DLBCL patients of 2 prospective LYmphoma Study Association (LYSA) trials. The first cohort (n = 639) was used for training using a 5-fold cross validation scheme. The second cohort (n = 94) was used for external validation of TMTV predictions. Ground truth masks were manually obtained after a 41% SUVmax adaptive thresholding of lymphoma lesions. A 3D U-net architecture with 2 input channels for PET and CT was trained on patches randomly sampled within PET/CTs with a summed cross entropy and Dice similarity coefficient (DSC) loss. Segmentation performath dissemination in routine practice and reproducibility of TMTV assessment in lymphoma patients.
Plasma chemerin, which has chemotactic and adipogenic functions, is increased in several inflammatory diseases. However, its relationship with multiple sclerosis (MS) has not been explored yet. In this study, we aimed to determine chemerin levels and their possible role in MS.
Chemerin serum concentrations were evaluated by using ELISA kit in 91 clinically definite MS patients and 52 healthy controls. The mean serum chemerin, insulin, and cholesterol levels were compared. Patients were divided into two groups according to the body mass index (BMI), and the relationships between clinical and metabolic parameters were evaluated.
Serum chemerin levels were 10.46 ± 1.65ng/mL in MS patients and 10.26 ± 2.14ng/mL in the control group. No significant difference was found between patients and controls (p = 0.55). PMSF cost We found no difference regarding age, gender, and BMI between two groups (p = 0.053, p = 0.54, p = 0.41). However, female patients with MS had higher chemerin levels than male patients. There were no associations between serum chemerin levels and EDSS score, annualized relapse rate, BMI, insulin resistance, and serum cholesterol levels in MS patients.
In this study, we aimed to determine serum chemerin levels in patients with MS. However, in our study, there was no significant difference between serum chemerin levels of MS patients and healthy controls'. Additionally, chemerin levels were not associated with other metabolic parameters, as well as cognitive dysfunction. Further studies are needed to evaluate the role of chemerin in MS patients.

FOLFOXIRI plus bevacizumab is regarded as a first-line therapeutic option for selected patients with metastatic colorectal cancer (mCRC). Our aim was to assess the efficacy and safety of induction treatment with FOLFOXIRI plus bevacizumab in patients with untreated mCRC harboring UGT1A1 wild (*1/*1), or single-hetero (*1/*6 or *1/*28) genotypes.
Twelve cycles of FOLFOXIRI plus bevacizumab were administered to patients with untreated mCRC. The primary endpoint was the overall response rate (ORR) assessed by central independent reviewers. Secondary endpoints included time to treatment failure (TTF), progression-free survival (PFS), overall survival (OS), relative dose intensity (RDI), R0 resection rate, and safety. The exploratory objectives were early tumor shrinkage (ETS) and depth of response (DoR).
Of the 47 patients enrolled, 46 and 44 patients were eligible for the safety and efficacy analysis, respectively. The primary endpoint was met. The ORR was 63.6% (95% CI 47.8-77.6). At a median follow-up of 25.4months, median TTF, PFS, and OS was 8.1, 15.5, and 34.4months, respectively. The median RDI of 5-fluorouracil, irinotecan, oxaliplatin, and bevacizumab was 72, 69, 62, and 71%, respectively. R0 resection rate was 22.7%. Grade 3 or higher adverse events (≥ 10%) included neutropenia (65.2%), febrile neutropenia (26.1%), leukopenia (23.9%), anorexia (10.9%), nausea (10.9%), and diarrhoea (10.9%). No treatment-related deaths were observed. ETS and DoR were 70.5 and 45.4%, respectively.
FOLFOXIRI plus bevacizumab induction treatment of Japanese patients was shown to be beneficial and manageable, although caution is required since the treatment causes febrile neutropenia.

Positron Emission Tomography-Computed Tomography (PET-CT) has been changing diagnostic and therapeutic strategies for patients with cancers, and several PET-CT-related prognostic factors have been reported. We have focused on metabolic tumor volumes (MTVs) over the whole body and in specific organs using 18F-PET-CT imaging, and have compared clinical data to know the prognosis of patients with diffuse large B cell lymphoma (DLBCL).
From January 2006 to December 2016, patients who were newly diagnosed for de novo DLBCL and who received 18F-FDG PET-CT scans for disease staging at Ehime University Hospital were reviewed.
A total of forty out of 108 patients with DLBCL were analyzed. The median and the average follow-up were 3.9years and 3.6years. Both MTV50 and MTV60 whole-body searching indicated effective prognostic values for patients with DLBCL statistically (P = 0.027). However, analysis of MTVs in the spleen and in bone marrow did not provide any prognostic value. Receiver operating characteristic (ROC) analysis indicated that the cutoff level 25.
