A comprehensive analysis of CDC20 overexpression in common malignant tumors from multiple organs: its correlation with tumor grade and stage

Abstract High expression of cell division cycle 20 homolog (CDC20), a key component of the spindle assembly checkpoint (SAC), has been reported in various malignancies and plays a vital role in tumorigenesis and progression. The goal of this study was to evaluate the utility of CDC20 immunostaining in a wide range of malignant tumors. CDC20 immunohistochemistry was evaluated in normal tissues and compared to the most frequently occurring malignant tumors in these tissues (bladder, breast, cervical, colonic, endometrial, gastric, head and neck, liver, lung, ovarian, pancreatic, prostatic, renal, thyroid carcinomas, and testicular seminoma). Normal/non-neoplastic tissues showed positive CDC20 expression in 19.44 % of all examined cases. CDC20 staining was negative in normal and non-neoplastic tissues from the bladder, cervix, liver, stomach, and thyroid. From the all malignant tumors examined 55.7 % showed high CDC20 expression while low expression was found in 44.3 %. High expression of CDC20 was associated with high tumor grade in the bladder (p = 0.027), cervical (p = 0.032), colonic (p = 0.026), endometrial (p = 0.016), gastric (p = 0.033), liver (p = 0.028), ovarian (p = 0.044), prostatic (p = 0.040), and renal (p = 0.048) carcinomas. There was a significant correlation between high CDC20 expression and advanced tumor stage in car...

ConclusionThe proposed multiparametric MRI-based SLICs+MTh method performs noninvasive assessment of NACT response in osteosarcoma that may improve cancer treatment monitoring, planning, and overall prognosis.Key Points• The simple linear iterative clustering supervoxels and Otsu multithresholding-based technique (SLICs+MTh) successfully estimates the proportion of necrosis, viable tumor, and edema in osteosarcoma in the course of chemotherapy.• The proposed technique is noninvasive and uses multiparametric MRI to measure necrosis as an indication of anticancer treatment response.• SLICs+MTh-based necrosis w...

Authors: Urban AE, CubaƂa WJ Abstract Eugeroics are a relatively new class of wakefulness-promoting agents. Thegroup includes adrafinil, modafinil and armodafinil. Modafinil is the most widely used and the best studied agent. Indications for the use of modafinil include the treatment of narcolepsy, shift-work sleep disorders and excessive daytime sleepiness associated with obstructive sleep apnea. Many studies show the utility of modafinil and armodafinil in the treatment of depression - both in monotherapy andas potentiation therapy if needed. Modafinil has proven to be effective in the treatment of residual symp...
