Combined Analysis of Intragastric Malignant Exfoliation and Ca 72.4 Concentration in Stomach Adenocarcinoma: The "GL1 Ca 72.4" Parameter.

Introduction/objective: Differently from other digestive malignancies, gastric cancer (GC) pathobiology is still little known and understood. Recently, cytopathology and molecular biology on gastric juice/gastric lavage (GJ/GL) of GC patients have provided novel and interesting results in terms of screening, diagnosis, prognosis, and therapy. However, entertaining cytologic examination and molecular test as a unified solo-run test is previously unreported.

Elevated Gastric Juice Carbohydrate Antigen 72.4 (Ca 72.4) Is an Independent Prognostic Factor of Poor Survival for Gastric Cancer Patients.

Background/aim: As of 2020, carbohydrate antigen 72.4 (Ca 72.4) has been rarely investigated in the gastric juice (GJ) of patients with gastric cancer (GC).

Gastric Lavage Malignant Cells (yGL) and Hypohemoglobinemia (yAnemia) as New Systems of Tumor Regression Grading and Prognostic Prediction for Gastric Cancer After Neoadjuvant Treatment.

Background/aim: Although reckoned necessary for survival benefit, neoadjuvant chemotherapy (NAC) of gastric cancer (GC) patients has so far provided questionable results. Consequently, searching for new and clearer systems of response to NAC, post-NAC re-evaluation and prognostic prediction appears essential. The purpose of this study was to examine endogastric cytopathology and hemoglobin level count as new features, potentially useful for GC patients after NAC.

Preoperative gastric lavage in gastric cancer patients undergoing surgical, endoscopic or minimally invasive treatment: An oncological measure preventing peritoneal spillage of intragastric cancer cells and development of related metastases.

In addition to classical metastatic pathways, recently gastric cancer was described having an alternative route called "endoluminal exfoliation". Provisional analyses demonstrated, in fact, this kind of shedding is associated with several clinico-pathological features indicative of aggressive behavior and resulted to be an independent prognostic factor entailing poor prognosis. Compared with non-sowing counterparts, in fact, patients affected with exfoliating early and advanced gastric carcinomas met with shorter overall survival, disease free survival, progression free survival and time to tumor progression.

Laparoscopic Intragastric Surgery for Treating Early Gastric Cancer.

Background/aim: Although there is an increasing number of studies on laparoscopic resection of early gastric cancer (EGC), as of 2018 no standardized strategy exists. We reviewed available literature dealing with laparoscopic intragastric (intraluminal) surgery (LIGS) conducted for patients with EGC to better define indications, benefits and limitations of this particular minimally invasive technique.

Materials And Methods: PubMed, MEDLINE, Science Direct, Scopus, Web of Science, Google Scholar and ResearchGate were the search engines investigated.

Gastric Cancer Cells in Peritoneal Lavage Fluid: A Systematic Review Comparing Cytological with Molecular Detection for Diagnosis of Peritoneal Metastases and Prediction of Peritoneal Recurrences.

Background/aim: Detecting free tumor cells in the peritoneal lavage fluid of gastric cancer patients permits to assess a more accurate prognosis, predict peritoneal recurrence and select cases for a more aggressive treatment. Currently, cytology and molecular biology comprise the two most popular methods of detection that are under constant study by researchers.

Materials And Methods: We burrowed into the available literature comparing cytological with molecular detection of free intraperitoneal gastric cancer cells.

Gastric Juice MicroRNAs as Potential Biomarkers for Screening Gastric Cancer: A Systematic Review.

Background/aim: To date, the combination of gastroscopy with biopsy remains the only test validated for screening gastric cancer (GC). Currently, analysis of circulating microRNAs (miRNAs or miRs) is providing interesting information on GC prognosis, but since these molecules are shared by several types of cancer, its clinical use could be questionable and difficult. MicroRNAs in gastric juice (GJ) could represent a cogent alternative to screening GC by biopsy.

Utility of Nasogastric Tube for Medical and Surgical Oncology of Gastric Cancer: A Prospective Institutional Study on a New and Precious Application of an Old and Economic Device.

Background/aim: Concerning gastric cancer (GC), nasogastric tube (NGT) is routinely employed for peri-operative decompression and palliative enteral nutrition. Additionally, we believe to have found a further application.

Patients And Methods: Between April 2012 and April 2017, 96 GC patients received preoperative nasogastric lavage (GL).

Presence of cancer cells in gastric lavage of gastric cancer patients as an indicator of advanced disease, predictor of tumour aggressive phenotype and independent prognostic factor for poor survival: The endoluminal metastatic pathway of gastric cancer and GL0/GL1 classification.

Objective: As of 2017, the pathobiology of gastric cancer (GC) is far from fully understood; consequently, new methods of basic and advanced research have been proposed and tested. The presence (GL1) vs absence (GL0) of malignant cells exfoliated in gastric lavage (GL) of GC patients was formerly evaluated with diagnostic intent but not for staging or prognostic assessment. We investigated this hitherto unreported application of cytopathology.

Blockade of Stearoyl-CoA-desaturase 1 activity reverts resistance to cisplatin in lung cancer stem cells.

Poor prognosis in lung cancer has been attributed to the presence of lung cancer stem cells (CSCs) which resist chemotherapy and cause disease recurrence. Hence, the strong need to identify mechanisms of chemoresistance and to develop new combination therapies. We have previously shown that Stearoyl-CoA-desaturase 1 (SCD1), the enzyme responsible for the conversion of saturated to monounsaturated fatty acids is upregulated in 3D lung cancer spheroids and is an upstream activator of key proliferation pathways β-catenin and YAP/TAZ.

Early Gastric Cancer Exfoliating into Gastric Lavage (GL1 EGC) Shows a More Aggressive Behavior and Poorer Survival Compared to the Non-Exfoliative Counterpart (GL0 EGC).

Background/aim: Early gastric cancer (EGC) is usually associated with excellent prognosis. Some cases, however, entail a poorer survival. Our aim was to assess if EGC exfoliating into gastric lavage (GL) has a more aggressive behavior than the non-exfoliative counterpart.

Cytological diagnostic features of late breast implant seromas: From reactive to anaplastic large cell lymphoma.

Late breast implant seroma may be the presentation of a breast implant-associated anaplastic large cell lymphoma (BI-ALCL), which claims for a prompt recognition. However, BI-ALCL diagnosis on fine-needle aspiration (FNA) might be challenging for pathologists lacking experience with peri-implant breast effusions. Sixty-seven late breast implant seromas collected by FNA from 50 patients were evaluated by Papanicolaou smear stain and immunocytochemistry on cell blocks.

Accuracy of Lung Ultrasound in Patients with Acute Dyspnea: The Influence of Age, Multimorbidity and Cognitive and Motor Impairment.

Discriminating between causes of dyspnea may be difficult, particularly in the elderly. The aim of this retrospective study of 83 inpatients with acute dyspnea was to assess the influence of age, multimorbidity and cognitive or motor impairment on the diagnostic accuracy of lung ultrasound (LUS) in discriminating acute heart failure (AHF) from noncardiogenic dyspnea (NCD). Univariate analysis indicates that LUS misdiagnosis was associated with the following parameters: history of stroke (p = 0.

Measuring Intragastric Tumor Markers in Gastric Cancer Patients: a Systematic Literature Review on Significance and Reliability.

As of 2017, no serum tumor marker has shown high levels of sensitivity or specificity for early detection, classification, staging, prediction and prognosis of patients affected by gastric cancer. In this regard, since 1975 several authors have investigated the gastric juice or gastric lavage of patients with gastric adenocarcinoma in order to determine the concentrations of intragastric tumor markers and discover the perfect antigen for this cancer. To date, however, a systematic review of the literature on intragastric tumor markers is still unreported.

Interobserver reproducibility of cytologic p16 /Ki-67 dual immunostaining in human papillomavirus-positive women.

Background: The accumulation of cyclin-dependent kinase inhibitor 2A (p16 ) protein in a cell is associated with neoplastic progression in precancerous cervical lesions. Dual staining for p16 and Ki-67 has been proposed as a triage test in cervical cancer screening for women who test positive for human papillomavirus DNA. In this study, interobserver reproducibility of the interpretation of this test was assessed.

Physical Activity and Other Determinants of Survival in the Oldest Adults.

Objectives: To determine the role of physical activity as a possible survival determinant in the oldest adults.

Design: Prospective, longitudinal, population-based cohort.

Setting: The Pianoro Study of community-dwelling older adults in three towns in northern Italy.

Integrated Use of Lung Ultrasound and Chest X-Ray in the Detection of Interstitial Lung Disease.

Background: Current data have shown that lung ultrasound (LUS) may be useful in the detection of interstitial lung disease (ILD) by the evaluation of B-lines, the sonographic marker of pulmonary interstitial syndrome. Nevertheless, no prospective study has compared LUS to chest X-ray (CXR) for ILD assessment, and there is no general agreement on the specific echographic diagnostic criteria for defining ILD.

Objectives: The aims of this study were (1) to compare the accuracy of LUS and CXR in the detection of ILD using high-resolution CT (HRCT) as the gold standard and (2) to compare the accuracy of different echographic diagnostic criteria for ILD diagnosis.

Exogenous lipoid pneumonia induced by nasal decongestant.

Introduction: Lipoid pneumonia is a clinical condition that may be initially asymptomatic or confused with an infectious or malignant lung disease.

Objectives: We report four cases of this pathological condition.

Methods: The first case concerned an 85-year old woman with bilateral confluent pulmonary opacities, ground-glass type.

Detection of cancer cells and tumor markers in gastric lavage of patients with gastric cancer: Do these findings have a clinicopathological significance and oncological implication?

Although decreasing in the incidence over the last years, currently gastric adenocarcinoma represents the second cause of cancer related-death worldwide. Further knowledge and novel therapies are desperately needed in order to make the prognosis of these patients more acceptable. Infact, even though in recent years numerous staging parameters have been largely studied and unanimously recognized for their clinical and prognostic value, today too many shadows still exist around the capacity to predict exactly the natural history or post-treatment behavior of this cancer even among patients of the same stage.

Analyzing Gastric Lavage of Gastric Cancer Patients: A Prospective Observational Study on Cytopathology and Determination of Intragastric CEA, CA 19.9, CA 72.4, and CA 50.

Objectives: To investigate gastric lavage (GL) cytopathology and immunometric analysis as novel clinicopathologic and prognostic parameters for gastric cancer (GC).

Study Design: In 38 patients with gastric adenocarcinoma, we performed a cytopathologic analysis and an immunometric assay of GL using four tumor markers (CEA, CA 19.9, CA 72.
