Lung cancer is the leading cancer in the world, accounting for 1.2 million of new cases annually, being responsible for 17.8% of all cancer deaths.

Our study assessed the relationship between CSCs and the relapse rate in patients harboring adenocarcinoma (ADL) and squamous cell carcinoma of the lung (SCCL).
Experimental Design: This is an observational prospective cohort study (NCT04634630) assessing the influence of CSC frequency on relapse rate after major lung resection in 35 patients harboring early (I-II) (n = 21) and locally advanced (IIIA) (n = 14) ADL and SCCL.
Emerging evidence suggests that a small subpopulation of cancer stem cells (CSCs) is responsible for initiation, progression, and metastasis cascade in tumors. CSCs share characteristics with normal stem cells, i.e.

Introduction And Importance: Mediastinal paragangliomas are rare neuroendocrine tumors that originate from extra-adrenal paraganglia, occasionally secreting catecholamines. Nonfunctional mediastinal paragangliomas present nonspecific clinical and radiological features and represent a diagnostic challenge.
Case Presentation: A 53-year old woman presented with cough and dyspnea increasing over time.
Introduction And Importance: Pleomorphic carcinoma of the lung is a rare malignant epithelial tumor. Due to its rarity, its clinicopathological characteristics are not clear, and there is no defined therapeutic path for this type of tumor.
Case Presentation: We retrospectively analyzed the medical and pathological reports of 8 patients who underwent surgical resection for pleomorphic carcinoma between 2007 and 2010.
Introduction: Lung cancer is one of the most common cancers in the world, causing over 1.7 million deaths in 2018. Thus far, no effective treatments against lung cancer for advanced stages have been found.

Different techniques can be used for fixation. The aim of this paper is to present a case in which Judet and Sanchez-Loret plates were employed and to discuss the usefulness of this traditional technique.
View Article and Find Full Text PDFCancer stem cells (CSCs) have been considered the key drivers of cancer initiation and progression due to their unlimited self-renewal capacity and their ability to induce tumor formation. Macrophages, particularly tumor-associated macrophages (TAMs), establish a tumor microenvironment to protect and induce CSCs development and dissemination. Many studies in the past decade have been performed to understand the molecular mediators of CSCs and TAMs, and several studies have elucidated the complex crosstalk that occurs between these two cell types.

It may have poor prognosis if not properly treated. Currently, conservative measures are the first line of treatment for managing chylothorax.

This type of cancer represents about 2% of all soft tissue sarcomas and has a high rate of metastasis through the hematogenous route. For the rarity of this malignant vascular tumor it is still challenging to set a diagnosis (1).

The etiology and pathogenesis are still unclear. Histopathological diagnosis focuses on cells that are positive for TTF1, EMA, cytokeratin-7, and CAM 5.

Clinical presentation includes swelling, pain and impairment of shoulder movements. The present literature relies only on few small case series.

Although the majority of these neoplasms have a benign clinical course, the malignant form has also been reported. The gold standard is surgical treatment for complete removal.

The most popular open technique for pectus excavatum repair was proposed by Ravitch in 1949 as an open approach that requires partial resection of the costal cartilage, xiphoid excision, and osteotomy of the sternum. The goal is to remove abnormal rib cartilage while preserving the perichondrium, allowing regrowth of the rib cartilage to the sternum in a more anatomic manner.

However, a comparison between ALDH high cells and CD44+ cells have been previously described with no significant correlation. Indeed, the aim of the present research is to identify a superficial marker able to match with ALDH high cells population in freshly isolated human lung cancer cells.

The aim of this study was to investigate the relationship between cannabis smoking, pneumothorax and bullous lung disease in a population of operated patients.
Methods And Findings: We performed a retrospective study on patients operated on for spontaneous pneumothorax.
In addition to the most common somatic lung cancer mutations (i. e., KRAS and EGFR mutations), other genes may harbor mutations that could be relevant for lung cancer.

Lung neuroendocrine cells tumor (NET) classification and diagnosis, particularly for typical and atypical carcinoids, are complicated by a variable natural history and nonspecific symptoms. Mechanisms for the development and progression of well-differentiated lung NETs are still unclear. An accurate and timely diagnosis can ensure the implementation of appropriate treatment and impact on prognosis.

PE is sometimes associated with cardiorespiratory impairment, but is often associated with psychological distress, especially for patients in their teenage years. Surgical repair of pectus deformities has been shown to improve both physical limitations and psychosocial well-being in children.

Their elusive nature may allow them to escape the immune response by tumor-infiltrating lymphocytes (TILs), which can positively affect the outcome in non-small cell lung cancer (NSCLC) patients. Despite independent investigations on both LCSCs and TILs, the relationship between the two has been very marginally considered.
View Article and Find Full Text PDFLung cancer stem cells (CSCs) share many characteristics with normal stem cells, such as self-renewal and multipotentiality. High expression of aldehyde dehydrogenase (ALDH) has been detected in many tumors, particularly in the CSC compartment, and it plays an important role in tumor proliferation, metastasis, and drug resistance. CD44 is commonly used as a cell surface marker of cancer stem-like cells in epithelial tumors.

Vacuum-assisted closure (VAC) is a well-established technical resource for treating complicated wounds; however, in cases of suspicion of bone infection, this approach is not enough to prevent bar removal.

The unifying element is the operability of the sternal metastasis if it is the only site of metastasis, on the operability of the primary site of the tumor and on the patient's health conditions.
