Regarding clinicopathologcial features; older patients (> 65) were more likely to express PD-L1 (>1 %) and IDO-1 (>20 %). For tumor size, IDO-1 expression (>5 %), along with PD-1/IDO-1 Co-expression (>1/5 %), was associated with larger tumor size (>5cm). For myometrial invasion, CSs with >50 % invasion were more likely to express IDO-1 (>20 %) and PD-1/IDO-1 (>1/5 %). Ultimately, the effect of IDO-1, PD-1 and PD-L1 on the clinical profile may be less important than its potential use as a immunotherapeutic, where safe and effective corresponding drugs could be used to treat particular patient populations. Future clinical trials are needed to decipher the association between immune check point inhibitor expression and therapeutic response. This is the only way to definitively prove immune checkpoint immunohistochemistry as predictive biomarkers in this cancer subtype. OBJECTIVE This study is aimed to analyze the clinical outcome of recurrent ovarian cancer patients bearing isolated lymph-node recurrence (ILNR) who underwent salvage lymphadenectomy (SL). The prognostic role of clinicopathological variables and the mutational status of BRCA1/2 have also been investigated. METHODS This retrospective, single-institutional study included women with platinum-sensitive lymph node recurrence underwent to SL between June 2008 and June 2018. Univariate and multivariate analysis was performed to evaluate the impact of clinical parameters, and BRCA1/2 mutational status on post salvage lymphadenectomy progression-free survival (PSL-PFS). RESULTS As of June 2019, the median follow-up after SL was 30 months, and the relapse has been documented in 48 (56.5%) patients. In the whole series, the median PSL-PFS was 21 months, and the 3-year PSL-PFS was 36.7%. The median PSL-PFS, according to patients with ILNR (N = 71) versus patients with lymph-nodes and other sites of disease (N = 14), was 27 months versus 12 months, respectively. Univariate analysis of variables conditioning PSL-PFS showed that platinum-free interval (PFI) ≥12 months, normal Ca125 serum levels, and number of metastatic lymph-nodes ≤3 played a statistically significant favorable role. In multivariate analysis, PFI duration ≥12 months and the number of metastatic lymph nodes ≤3 were shown to keep their favorable, independent prognostic value on PSL-PFS. KN-62 manufacturer CONCLUSIONS In the context of SL, the patients with long PFI and low metastatic lymph node numbers at ILNR diagnosis have the best outcome. The BRCA mutational status seems not associated with clinical variables and PSL-PFS, differently from other sites of disease in ROC patients. AIMS A significant proportion of patients with brain metastases have a poor prognosis, with a life expectancy of 3-6 months. To determine the optimal radiotherapeutic strategy for brain metastases in this population, we conducted a randomised feasibility study of whole brain radiotherapy (WBRT) versus stereotactic radiosurgery (SRS). MATERIALS AND METHODS Patients with a life expectancy of 3-6 months and between one and 10 brain metastases with a diameter ≤4 cm were enrolled at six Canadian cancer centres. Patients were randomly assigned (11) to receive either WBRT (20 Gy in five fractions) or SRS (15 Gy in one fraction). The primary end point was the rate of accrual per month. Secondary feasibility and clinical end points included the ratio of accrued subjects to screened subjects. This trial is registered with ClinicalTrials.gov (number NCT02220491). RESULTS In total, 210 patients were screened to enrol 22 patients into the trial; 20 patients were randomised between the two arms. Two patients did not receivwith accurate prognostication were identified as issues in this feasibility study. A larger phase III randomised trial is planned to determine the optimal treatment in this patient population. Ultrastructural studies of the male gamete provide relevant complementary data of value for the clinical assessment of semen quality and assist in determining phylogenetic and structural/functional relationships. This is illustrated using semen samples and testicular material from vulnerable wild animals (cheetah and rhinoceros), commercially exploited exotic birds (ratites and tinamou) and poultry (chicken and duck). Transmission electron microscopy (TEM) was employed to record sperm and spermatid ultrastructural detail on a comparative basis. The power of the technique was demonstrated using normal and abnormal (the knobbed acrosome defect) formation of the acrosome in the cheetah and rhinoceros. The structural similarities of the defect across species was apparent. The determination of phylogenetic associations was illustrated by comparing structural characteristics between ratites (ostrich, emu and rhea), the tinamou and poultry (chicken and duck), highlighting the morphological peculiarities evident in the midpiece and proximal principal piece of the sperm tail. A clear distinction was obvious between the ratites and tinamou on the one hand and the Galliform and Anseriform birds on the other. The potential power of using molecular techniques in conjunction with ultrastructural studies to explain structural/functional relationships was demonstrated by describing a transient elaboration of the perinuclear theca that occurs during a specific stage of spermiogenesis in ratites, and which can only be imaged using TEM. The inherent aesthetic appeal of the structurally complex normal and defective male gamete was also emphasised. Data science and digital technologies have the potential to transform diagnostic classification. Digital technologies enable the collection of big data, and advances in machine learning and artificial intelligence enable scalable, rapid, and automated classification of medical conditions. In this review, we summarize and categorize various data-driven methods for diagnostic classification. In particular, we focus on autism as an example of a challenging disorder due to its highly heterogeneous nature. We begin by describing the frontier of data science methods for the neuropsychiatry of autism. We discuss early signs of autism as defined by existing pen-and-paper-based diagnostic instruments and describe data-driven feature selection techniques for determining the behaviors that are most salient for distinguishing children with autism from neurologically typical children. We then describe data-driven detection techniques, particularly computer vision and eye tracking, that provide a means of quantifying behavioral differences between cases and controls.
