How Progesterone Receptor Expression Impacts Platinum Sensitivity in Ovarian Clear Cell Carcinoma: Insights from Clinical and Experimental Perspectives.

Ovarian clear cell carcinoma (OCCC) is often considered a relatively platinum-resistant malignancy. The aim of this study was to explore the influence of progesterone receptor (PR) expression levels on platinum sensitivity and survival outcomes in people with OCCC. A retrospective analysis was conducted with 80 people with OCCC who underwent surgery followed by adjuvant chemotherapy.

Artificial Intelligence Model for a Distinction between Early-Stage Gastric Cancer Invasive Depth T1a and T1b.

Endoscopic submucosal dissection (ESD) is a widely accepted treatment for patients with mucosa (T1a) disease without lymph node metastasis. However, the inconsistency of inspection quality of tumor staging under the standard tool combining endoscopic ultrasound (EUS) with computed tomography (CT) scanning makes it restrictive. We conducted a study using data augmentation and artificial intelligence (AI) to address the early gastric cancer (EGC) staging problem.

Estrogen/Progesterone Receptor Expression and Cancer Antigen 125 Level as Preoperative Predictors to Estimate Lymph Node Metastasis in Endometrioid Endometrial Cancer.

Loss of estrogen receptor/progesterone receptor (ER/PR) in endometrial cancer (EC) is associated with tumor progression and poor outcomes. Elevated pretreatment cancer antigen 125 (CA 125) level is a risk factor for lymph node metastasis (LNM). We evaluated whether the combination of ER/PR expression and CA 125 level could be used as a biomarker to predict LNM.

Prediction of extranodal extension in head and neck squamous cell carcinoma by CT images using an evolutionary learning model.

Background: Extranodal extension (ENE) in head and neck squamous cell carcinoma (HNSCC) correlates to poor prognoses and influences treatment strategies. Deep learning may yield promising performance of predicting ENE in HNSCC but lack of transparency and interpretability. This work proposes an evolutionary learning method, called EL-ENE, to establish a more interpretable ENE prediction model for aiding clinical diagnosis.

Case report: Durable response after pembrolizumab in combination with radiation - induced abscopal effect in platinum - refractory metastatic endometrial clear cell carcinoma.

Deep neural network trained on gigapixel images improves lymph node metastasis detection in clinical settings.

The pathological identification of lymph node (LN) metastasis is demanding and tedious. Although convolutional neural networks (CNNs) possess considerable potential in improving the process, the ultrahigh-resolution of whole slide images hinders the development of a clinically applicable solution. We design an artificial-intelligence-assisted LN assessment workflow to facilitate the routine counting of metastatic LNs.

Quantitative Measurement of Progesterone Receptor Immunohistochemical Expression to Predict Lymph Node Metastasis in Endometrial Cancer.

Background: Previous studies have shown that loss of progesterone receptor (PR) in endometrial cancer (EC) is associated with poor outcomes. Evaluating lymph node metastasis (LNM) is essential, especially before surgical staging. The aim of this study was to investigate the role of PR expression and other clinicopathological parameters in LNM and to develop a prediction model.

Impaired Wnt/beta-catenin and protein patched homolog 1 signaling in extraocular sebaceous carcinoma: A clinical and histopathological study.

Downregulation of Notch3 links TIMP3 inhibition to suppress aggressive phenotypes of pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC), one of the most deadly digestive cancers, has a poor 5-year survival rate and is resistant to chemotherapeutic agents, such as gemcitabine. Notch3 plays an important role in cancer progression, and its expression facilitates chemoresistance in cancers. This study examined the clinical significance of Notch3 and explored the mechanisms through which it may affect disease progression in PDAC.

The role of prolonged progestin treatment and factors predicting successful fertility-sparing treatment for early endometrial endometrioid adenocarcinoma.

Objective: Fertility-sparing progestin therapy is highly effective in selected young women with endometrial cancer. In present study, we attempted to evaluate the role of prolonged medication and identify factors predicting successful treatment, and also assess fertility outcomes among young women with early stage endometrial endometrioid carcinoma (EC).

Study Design: We retrospectively reviewed clinical data from patients aged <45 years with well-differentiated EC at presumed stage IA (without myometrial invasion) who wished to preserve fertility.

Factors associated with the inconsistent diagnosis between frozen section and permanent pathologic examination in borderline ovarian tumors.

Aim: The predictive accuracy of frozen sections for borderline ovarian tumors (BOTs) is suboptimal. The aim of this study was to determine the diagnostic accuracy of BOTs and factors associated with an upgrade to a permanent pathological diagnosis of invasive carcinoma in patients diagnosed with BOTs by frozen section.

Methods: We conducted a retrospective study between 2011 and 2018 at Kaohsiung Chang Gung Memorial Hospital (KCGMH).

GNA11 joins GNAQ and GNA14 as a recurrently mutated gene in anastomosing hemangioma.

Anastomosing hemangioma (AH) is a distinct benign vascular tumor that may be histologically confused with an angiosarcoma. Recently, recurrent GNAQ and GNA14 mutations were identified in AH. GNA11, another paralogue of GNAQ and the one that shows the highest degree of homology to GNAQ, has not yet been found to be mutated in AH.

Impact of Prognostic Nutritional Index on Overall Survival for Patients with Metastatic Urothelial Carcinoma.

Prognostic nutritional index (PNI) has been studied in various types of cancer which is significantly correlated with prognosis. The study aims to investigate the predictive role of PNI in patients with metastatic urothelial carcinoma (mUC) treated with systemic chemotherapy. We retrospectively reviewed 141 patients with mUC who received systemic chemotherapy.

Positive expression of Midkine predicts early recurrence and poor prognosis of initially resectable combined hepatocellular cholangiocarcinoma.

Background: Post-surgical prognosis is usually poor for combined hepatocellular cholangiocarcinoma (CHCC-CC), a rare primary liver cancer. Although midkine (MK) is a prognostic biomarker for several known cancers, it is not known whether it can be used as such in resectable CHCC-CC. This study examined whether MK expression can predict recurrence and survival in patients with resectable CHCC-CC.

BRAF and KRAS mutations in tubular apocrine adenoma and papillary eccrine adenoma of the skin.

Tubular apocrine adenoma (TAA) and papillary eccrine adenoma (PEA) are benign sweat gland tumors. Their names imply that they exhibit apocrine and eccrine differentiation, respectively. However, morphologically they are very similar and are often indistinguishable.

Progression of Idiopathic Eruptive Macular Pigmentation in a Girl from Childhood to Adolescence: Case Report and Literature Review.

A 14-year-old girl developed brownish round macules and patches over the face, trunk, and proximal limbs with extensive progression since she was 7 years old. Electron microscopy examination revealed an increase in the number and maturity of melanosomes in basal and suprabasal keratinocytes, although the number of melanocytes was within the normal range. A diagnosis of idiopathic eruptive macular pigmentation was made.

Transcriptomic reappraisal identifies MGLL overexpression as an unfavorable prognosticator in primary gastrointestinal stromal tumors.

The role of deregulated cellular metabolism, particularly lipid metabolism, in gastrointestinal stromal tumors (GISTs) remains unclear. Through data mining of published transcriptomes, we examined lipid metabolism-regulating drivers differentially upregulated in high-risk cases and identified monoglyceride lipase (MGLL) as the top-ranking candidate involved in GIST progression. MGLL expression status was examined in three GIST cell lines and two independent sets of primary localized GISTs.
