Abstract
A 35-year-old Japanese man who had experienced hoarseness for 10 years presented with a vocal cord lesion. A gross examination revealed a left vocal cord polyp occupying two-thirds of the vocal space. The endoscopically resected lesion contained scattered atypical fibroblastic, stellate, or ganglion-like cells with mucoid stroma. Vacuolated cells were also seen. Lymphoplasmacytic infiltrate was largely undetectable. A vocal cord polyp was first suspected, but well-differentiated liposarcoma and inflammatory myofibroblastic tumor (IMT) were included in the differential diagnoses. The tumor cells were positive for anaplastic lymphoma kinase (ALK), calponin, and vimentin, and negative for other smooth muscle markers by immunohistochemistry. Structures resembling myofibroblasts were not observed by electron microscopy, which confirmed abundant rough endoplasmic reticulum in the tumor cells and accumulated lipid droplets in some tumor cells. ALK gene rearrangement was detected by fluorescence in situ hybridization, and TIMP3-ALK fusion was confirmed by 5' rapid amplification of cDNA ends. We diagnosed the lesion as an IMT, and an ALK-rearranged stellate cell tumor may be postulated. This is the first report of a fusion partner gene of ALK in a case of laryngeal IMT.

Abstract
This study aims to examine the expression of p53, p16, and murine double minute 2 (MDM2) protein in normal endometrium and endometriosis, in order to discuss the role of p53, p16, and MDM2 protein and apoptosis in the pathogenesis and development of endometriosis, and provide a theoretical basis for clinical diagnosis and treatment.The immunohistochemical streptavidin-biotin peroxidase method was used to detect the expression of p53, p16, and MDM2 in tissue samples obtained from 30 women with pathologically confirmed ovarian endometriosis and 29 women with pathologically confirmed normal endometrium. The relationship between p53, p16, and MDM2 expression and apoptosis was analyzed.In normal endometrium, the positive rate of p53 in the secretory phase was higher than that in the proliferative phase (P < .05). Furthermore, the positive rate of p53 in normal endometrium was higher than that in ovarian endometriosis (P < .05). There was a significant difference between normal endometrium and ovarian endometriosis.The positive rate of p16 in normal endometrium was higher than that in ovarian endometriosis (P < .05). Furthermore, there was a significant difference between normal endometrium and ovarian endometriosis. The positive rate of MDM2 in normal endometrium was lower than that in ovarian endometriosis (P < .05).In ovarian endometriosis, the expression of p53 and p16 was positively correlated with each other (r = 0.611, P < .01). However, the expression of p53 and MDM2 was negatively correlated with each other (r = -0.541, P < .01). Furthermore, the expression of p16 and MDM2 might not be relevant in the endometriosis (r = 0.404, P > .05).As important apoptosis regulatory genes, p53, p16, and MDM2 might be involved in the pathogenesis and development of endometriosis.

Abstract
INTRODUCTION The main cause of anastomotic leakage (AL) is tissue hypoxia, which results from impaired perfusion of the pedicle stomach graft after esophageal reconstruction. Clinical judgment is unreliable in determining graft perfusion. Therefore, an objective, validated, and reproducible method is urgently needed. Near infrared fluorescence perfusion imaging using indocyanine green (ICG) is an emerging and promising modality. This study's objectives are to evaluate the feasibility of quantification of ICG angiography (ICGA) to assess graft perfusion and to validate ICGA by comparison with hemodynamic parameters, blood and tissue expression of hypoxia-induced markers, and tissue mitochondrial respiration rates. And, second, to evaluate its ability to predict AL in patients after minimally invasive esophagectomy (MIE). METHODS Patients (N = 70) with resectable esophageal cancer will be recruited for standard MIE. ICGA will be performed after graft creation and thoracic pull-up. Dynamic digital images will be obtained starting after intravenous bolus administration of ICG. The resulting images will be subjected to curve analysis and to compartmental analysis based on the adiabatic approximation to tissue homogeneity kinetic model. The calculated perfusion parameters will be compared to intraoperative hemodynamic data to evaluate the effects of patient hemodynamics. To verify whether graft perfusion represents tissue oxygenation, ICGA perfusion parameters will be compared with systemic and serosa lactate from the stomach graft. In addition, perfusion parameters will be compared to tissue expression of hypoxia-related markers and mitochondrial chain respiratory rate. Finally, the ability of functional, histological, and cellular perfusion and oxygenation parameters to predict AL and postoperative morbidity in general will be evaluated using the appropriate univariate and multivariate statistical analyses. DISCUSSION The results of this project may lead to a novel, reproducible, and minimally invasive method to objectively assess perioperative anastomotic perfusion during MIE, potentially reducing the incidence of AL and its associated severe morbidity and mortality. TRIAL REGISTRATION Clinicaltrials.gov registration number is NCT03587532. The study was approved by the ethical committee of the Ghent University, Belgium (B670201836427).

Abstract
Pancreatic liposarcoma is a malignant tumor originated from the pancreas mesenchymal tissue and mostly presented in skin, subcutaneous, periosteum, and long bone on both sides. Both conventional chemotherapy and radiotherapy have limited efficacy and poor prognosis for advanced pancreatic liposarcoma. Here, we reported a case of advanced pancreatic liposarcoma and reviewed the literature specific for liposarcoma of the pancreas and discuss the emerging options of treatment. The patient was treated with apatinib and a cross-line rescue therapy combined with paclitaxel after progressive disease. The therapeutic effect of the combination regimen has been evaluated. Apatinib is an oral tyrosine kinase inhibitor targeting the intracellular domain of vascular endothelial growth factor receptor-2 (VEGFR-2), which has dual effects of anti-angiogenesis and anti-tumor cell proliferation. To our knowledge, this is the first case to report the successful use of apatinib for advanced pancreatic liposarcoma.
