Distribution Characteristics in Clinical Phenotype and Immunohistochemistry of STK11 Adnexal Tumors: Case Report and Narrative Synthesis.

adnexal tumors are recently named tumors of the female adnexal region, associated with Peutz-Jeghers syndrome (PJS). There is a lack of studies on the clinical phenotypes of PJS concerning the pathology and molecular characteristics of adnexal tumors. We searched for 781 relevant studies through PubMed and Web of Science, and preliminary statistical and grouping comparisons were made using the screened study data combined with our patient.

The clinicopathological significance of thymic epithelial markers expression in thymoma and thymic carcinoma.

Background: The classification of thymomas is based on the morphology of epithelial tumor cells and the proportion of lymphocytes. Type A thymomas are composed of the spindle or oval tumor epithelial cells. Tumor cells of B thymomas are epithelioid-shaped with increasing atypia.

Malignant Mixed Epithelial and Stromal Tumor of the Kidney: Report of a Carcinosarcoma Case and an Updated Literature Review.

Mixed epithelial and stromal tumors of the kidney (MESTK) are rare and recently defined entities that comprise both epithelial and stromal cells. MESTK is mostly benign; however, to date, 18 borderline or malignant cases have been reported. In this study, we report a case of carcinosarcoma exhibiting a large carcinoma and small sarcoma component, and review the relevant literature.

Giant nodular fasciitis originating from the humeral periosteum: A case report.

Background: Nodular fasciitis (NF) is a self-limiting tumor that mostly occurs in the subcutaneous superficial fascia. NF originating from the appendicular periosteum is extremely rare. A large NF lesion of periosteal origin can be misdiagnosed as a malignant bone tumor and may cause overtreatment.

Ubiquitin C-terminal hydrolase-L1 expression in non-small-cell lung cancer and its association with clinicopathological features and prognosis.

UbiquitinC-terminal hydrolase-L1 (UCH-L1) is a cysteine hydrolase. It functions as a ubiquitin hydrolase, stabilizes the ubiquitin monomer, and affects cell division through cell cycle protein deubiquitination. Abnormal UCH-L1 expression is closely related to the occurrence and development of several tumors.

PD-L1 expression and immune stromal features in HPV-independent cervical adenocarcinoma.

Aims: Human papilloma virus (HPV)-independent cervical adenocarcinoma (CA) is usually diagnosed at an advanced stage, while the therapeutic options are limited. Therefore, effective treatment options are required. The programmed cell death 1 (PD-1) inhibitor pembrolizumab has been approved for the treatment of patients with recurrent or metastatic cervical squamous cell carcinoma expressing PD-ligand 1 (PD-L1).

Differential Expression of PD-L1 in Central and Peripheral and TTF1-Positive and -Negative Small-Cell Lung Cancer.

Central and peripheral location as well as thyroid transcription factor-I (TTF-1) expression was reported to be associated with different characteristics and prognosis of small-cell lung cancer (SCLC). This study aimed to investigate differential expression of PD-L1 in different SCLC subtypes, and in biopsy and resection specimens. We retrospectively analyzed 142 SCLC tumor samples using immunohistochemistry to correlate PD-L1 (22C3) expression with clinicopathologic features and survival data.

Diagnostic Challenge of Sarcomatoid Variant of ALK-Positive Anaplastic Large Cell Lymphoma: Case Report and Updated Systematic Literature Review.

The sarcomatoid variant of anaplastic large cell lymphoma is an extremely rare histologic pattern of anaplastic large cell lymphoma that consists of spindle-shaped neoplastic cells and is easily misdiagnosed as a soft tissue sarcoma. We report a case of the sarcomatoid variant of anaplastic large cell lymphoma that was initially diagnosed as an inflammatory myofibroblastic tumor in our hospital and as liposarcoma after consultation. This article analyzed the features of this entity by reviewing the literature.

Comprehensive analysis of spread through air spaces in lung adenocarcinoma and squamous cell carcinoma using the 8th edition AJCC/UICC staging system.

Background: This study aimed to comprehensively investigate the effect of spread through air spaces (STAS) on clinicopathologic features, molecular characteristics, immunohistochemical expression, and prognosis in lung adenocarcinomas (ADC) and squamous cell carcinomas (SQCC) based on the 8th edition AJCC/UICC staging system.

Methods: In total, 303 ADC and 121 SQCC cases were assessed retrospectively. Immunohistochemical staining was performed for E-cadherin, vimentin, Ki67, survivin, Bcl-2, and Bim.

Biomass pyrolysis with alkaline-earth-metal additive for co-production of bio-oil and biochar-based soil amendment.

The alkaline-earth-metal (AEM) has a good performance on modification of both bio-oil and biochar during biomass pyrolysis. In this work, the pyrolysis of rice husk (RH) in the presence of CaO, CaCO, MgO and MgCO was comparatively studied for selecting an appropriate AEM additive to balance the qualities of pyrolytic products. Pyrolysis of RH with the AEM additives could decrease the acids content and increase the hydrocarbons content in bio-oil.

Spread Through Air Spaces (STAS) in Lung Cancer: A Multiple-Perspective and Update Review.

Background: Spread through air spaces (STAS) is a spreading phenomenon of lung cancers, which is defined as tumor cells within air spaces in the lung parenchyma beyond the edge of the main tumor. To date, several articles have reviewed the studies concerning the significance of STAS; however, most articles focused on the prognosis without summarizing the significance of STAS on other aspects. In this review, we comprehensively summarized the current literature related to STAS, so as to explore the clinical significance of STAS from multiple perspectives.

Clinicopathologic Features and Genetic Alterations in Adenocarcinoma In Situ and Minimally Invasive Adenocarcinoma of the Lung: Long-Term Follow-Up Study of 121 Asian Patients.

Background: Adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA) are both small tumors with good prognosis after surgical resection, and most of them present as ground glass opacities (GGOs) on computed tomography (CT) screening. However, the differences in clinicopathologic features and genetic alterations between AIS and MIA are poorly elaborated, and few studies have evaluated the prognosis of MIA with different invasive components. Meanwhile, the histological features of lung lesions presenting as unchanged pure GGOs are barely understood.

Pyrolysis and combustion kinetics of lignocellulosic biomass pellets with calcium-rich wastes from agro-forestry residues.

The pyrolysis and combustion kinetics of biomass pellets (i.e., rice husk, herb residue, and wood residue) with the calcium-rich wastes (i.

Proscillaridin A induces apoptosis, inhibits STAT3 activation and augments doxorubicin toxicity in prostate cancer cells.

Cardiac glycosides are natural compounds used for the treatment of congestive heart failure and cardiac arrhythmias. Recently, they have been reported to exhibit anticancer activity. Proscillaridin A (PSN-A), a cardiac glycoside constituent of has been shown to exhibit anticancer activity.
