Article Synopsis
  • * The meta-analysis included data from 17 studies, revealing that VEIL had significantly lower rates of major complications compared to OIL (12.6% vs. 41.1%), though other factors like blood loss and hospital stay were similar between the two methods.
  • * While VEIL appears to be a safer option, OIL is quicker, making it a valid alternative; further randomized trials are needed to better assess these outcomes.

Article Synopsis
  • The study investigates the combination of a plasma 24-microRNA signature classifier (MSC) with low-dose computed tomography (LDCT) to improve screening strategies for lung cancer in 1024 participants with suspicious findings.
  • Results showed that MSC testing significantly increased the risk of lung cancer incidence and mortality in patients with positive LDCT results, highlighting the classifier's effectiveness for determining individual risk.
  • The findings suggest that using MSC in routine LDCT screening enhances the accuracy of predicting lung cancer and supports its role in managing uncertain radiologic findings.

Colorectal cancer (CRC) is a global health concern, and the incidence of early onset (EO) CRC, has an upward trend. This study delves into the genomic landscape of EO-CRC, specifically focusing on pediatric (PED) and young adult (YA) patients, comparing them with adult (AD) CRC. In this retrospective monocentric investigation, we performed targeted next-generation sequencing to compare the mutational profile of 38 EO-CRCs patients (eight PED and 30 YA) to those of a 'control group' consisting of 56 AD-CRCs.

Background: Epithelial to mesenchymal transition (EMT) endows cancer cells with pro-metastatic properties, which appear most effective when cells enter an intermediate hybrid (H) state, characterized by integrated mesenchymal (M) and epithelial (E) traits. The reasons for this advantage are poorly known and, especially, it is totally unexplored whether the interplay between H-cells and NK cells could have a role. Here we characterize the pro-metastatic mechanics of non-small cell lung cancer (NSCLC) H-cells and their subset of cancer-initiating cells (CICs), dissecting crucial interactions with NK cells.

Background: About 10% of NSCLCs are mutated in KRAS and impaired in STK11/LKB1, a genetic background associated with poor prognosis, caused by an increase in metastatic burden and resistance to standard therapy. LKB1 is a protein involved in a number of biological processes and is particularly important for its role in the regulation of cell metabolism. LKB1 alterations lead to protein loss that causes mitochondria and metabolic dysfunction that makes cells unable to respond to metabolic stress.

Background: Different strategies have been proposed for the treatment of locally advanced cervical cancer (LACC), with different impacts on patient's quality of life (QoL). This study aimed to analyze urinary, bowel, and sexual dysfunctions in a series of LACC patients who underwent chemotherapy, radiotherapy, radical surgery, or a combination of these treatments.

Methods: Patients with LACC who underwent neoadjuvant radio-chemotherapy (NART/CT; = 35), neoadjuvant chemotherapy (NACT; = 17), exclusive radio-chemotherapy (ERT/CT; = 28), or upfront surgery (UPS; = 10) from November 2010 to September 2019 were identified from five oncological referral centers.

Chronic obstructive pulmonary disease (COPD) is a risk factor for lung cancer development. COPD induces activation of hypoxia-induced signaling, causing remodeling of surrounding microenvironmental cells also modulating the release and cargo of their extracellular vesicles (EVs). We aimed to evaluate the potential role of circulating EVs from COPD subjects in lung cancer onset.

The interfacial properties of a planar SnO/κ-GaO p-n heterojunction have been investigated by capacitance-voltage (-) measurements following a methodological approach that allows consideration of significant combined series resistance and parallel leakage effects. Single-frequency measurements were carried out in both series- and parallel-model measurement configurations and then compared to the dual-frequency approach, which permits us to evaluate the depletion capacitance of diode independently of leakage conductance and series resistance. It was found that in the bias region, where the dissipation factor was low enough, they give the same results and provide reliable experimental - data.

Endometriosis and irritable bowel syndrome (IBS) are chronic conditions affecting up to 10% of the global population, imposing significant burdens on healthcare systems and patient quality of life. Interestingly, around 20% of endometriosis patients also present with symptoms indicative of IBS. The pathogenesis of both these multifactorial conditions remains to be fully elucidated, but connections to gut microbiota are becoming more apparent.

Introduction: Given the growing interest in sentinel node mapping (SLN) biopsy in Endometrial Cancer (EC) patients, many efforts have been made to maximize the SLN bilateral detection rate. However, at present, no previous research assessed the potential correlation between primary EC location in the uterine cavity and SLN mapping. In this context, this study aims to investigate the possible role of intrauterine EC hysteroscopic localization in predicting SLN nodal placement.

Objective: Endometrial cancer is the most common gynecologic neoplasm. To date, international guidelines recommend sentinel lymph node biopsy for low-risk neoplasms, while systematic lymphadenectomy is still considered for high-risk cases. This study aimed to compare the long-term survival of high-risk patients who were submitted to sentinel lymph node biopsy alone versus systematic pelvic lymphadenectomy.

Hyperprogressive disease (HPD), an aggressive acceleration of tumor growth, was observed in a group of cancer patients treated with anti-PD1/PDL1 antibodies. The presence of a peculiar macrophage subset in the tumor microenvironment is reported to be a sort of "immunological prerequisite" for HPD development. These macrophages possess a unique phenotype that it is not clear how they acquire.

Adolescents and young adults (AYA) with rhabdomyosarcoma (RMS) form a subgroup of patients whose optimal clinical management and best possible access to care remain a challenge and whose survival rates lag behind that of children diagnosed with histologically similar tumors. A better understanding of tumor biology that differentiates children (PEDS-) from AYA-RMS could provide critical information and drive new initiatives to improve their final outcome. We investigated the functional role of miRNAs implicated in AYA-RMS development, as they have the potential to lead to discovery of new targets pathways for a more tailored treatment in these age groups of young RMS patients.

Article Synopsis
  • Researchers studied a type of lung cancer called Non Small Cell Lung Cancer (NSCLC) and found that the commonly used test for a protein called PD-L1 is not very good at showing how well treatments will work, especially in patients with low levels of this protein.
  • They looked at tiny particles from the blood, called EVs, in 64 patients with low PD-L1 who were treated with immune therapies, and found that those who responded better to treatment had specific markers on their EVs.
  • The study suggests that measuring certain markers on these EVs could help doctors figure out which patients are more likely to benefit from immune therapies for their cancer.
