Effects of a low-power He-Ne laser on the healing of experimental colon anastomoses: our experience
1992
Despite technical advances, the incidence of anastomotic leaks in elective colorectal surgery remains around 14%. Recent studies suggest that the use of low-energy lasers may enhance wound healing in different tissues in a selective, nondestructive manner. Based on these findings we have attempted to provide experimental background on the effects of a He-Ne laser during the early stages of healing in 155 colonic anastomoses performed on rats. The irradiation (external or endoscopical) ofthe anastomoses by repeated doses below 4 J/cm 2 suggest (1) the laser-induced enhancement of anastomotic healing can be obtained in both healthy colons or in situations in which anastomotic breakdown is mor…
Risk-Reducing Gynecological Surgery in Lynch Syndrome: Results of an International Survey from the Prospective Lynch Syndrome Database.
2020
Purpose: To survey risk-reducing hysterectomy and bilateral salpingo-oophorectomy (BSO) practice and advice regarding hormone replacement therapy (HRT) in women with Lynch syndrome. Methods: We conducted a survey in 31 contributing centers from the Prospective Lynch Syndrome Database (PLSD), which incorporates 18 countries worldwide. The survey covered local policies for risk-reducing hysterectomy and BSO in Lynch syndrome, the timing when these measures are offered, the involvement of stakeholders and advice regarding HRT. Results: Risk-reducing hysterectomy and BSO are offered to path_MLH1 and path_MSH2 carriers in 20/21 (95%) contributing centers, to path_MSH6 carriers in 19/21 (91%) and…
Cancer-Initiating Cells from Colorectal Cancer Patients Escape from T Cell-Mediated Immunosurveillance In Vitro through Membrane-Bound IL-4
2014
Abstract Cancer-initiating cells (CICs) that are responsible for tumor initiation, propagation, and resistance to standard therapies have been isolated from human solid tumors, including colorectal cancer (CRC). The aim of this study was to obtain an immunological profile of CRC-derived CICs and to identify CIC-associated target molecules for T cell immunotherapy. We have isolated cells with CIC properties along with their putative non-CIC autologous counterparts from human primary CRC tissues. These CICs have been shown to display “tumor-initiating/stemness” properties, including the expression of CIC-associated markers (e.g., CD44, CD24, ALDH-1, EpCAM, Lgr5), multipotency, and tumorigenic…
Descriptive study on subjective experience of genetic testing with respect to relationship, family planning and psychosocial wellbeing among women wi…
2021
AbstractBackgroundDue to increased risk of endometrial and ovarian cancer, women belonging to known Lynch Syndrome (LS) families are recommended to undergo germline testing. Current practice in Finland is to offer counselling to women with pathogenic variant and advocate risk-reducing surgery (RRS) after completion of childbirth. The present study aimed to clarify the impacts of positive germline testing on family planning and reproductive decisions of these women, which are relatively unknown.MethodsSeventy-nine carriers of germline MMR gene pathogenic variant (path_MMR)were identified from the Finnish LS Registry as having genetic testing performed before the age of 45 years and not havin…
Liquid biopsy in colorectal carcinoma: the search for potential prognostic and predictive biomarkers
Background: Liquid biopsy is considered a repeatable, non-invasive and dynamic tool. It could be able to recover from liquid samples (expecially blood)) cancer-specific informations (miRNAs, circulating-free DNA (cfDNA), circulating tumor DNA (ctDNA) and exosomes) by overcoming the limitations associated with traditional tissue biopsy. Aim: to investigate the potential prognostic and predictive role of blood cancer-related biomarkers such as cfDNA or ctDNA and exosomal DNA in colorectal cancer (CRC) patients. Results: cfDNA or ctDNA and exosomal DNA could have a potential applicability in CRC management. New generation technologies are able to identify clinically relevant genomic alteration…

Tertiary lymphoid structures in pulmonary metastases of microsatellite stable colorectal cancer
2023
Tertiary lymphoid structures (TLSs) are ectopic lymphoid aggregates located at sites of chronic inflammation and recognized as prognosticators in several cancers. We aimed to analyse the prognostic effect of TLSs in colorectal cancer (CRC) pulmonary metastases and primary tumours, with a comparison to the CD3+ and CD8+ cell density-based immune cell score (ICS). For TLS density and TLS maximum diameter analysis, 67 pulmonary metastases and 63 primary tumours were stained with haematoxylin and eosin. For ICS scoring and analysis, CD3 and CD8 immunohistochemistry was performed. Excellent interobserver agreement was achieved in all TLS measurements. Of all patients, 36 patients had low TLS den…
Il restauro come pelle: Villa Antonietta a Palermo
2010
ABSTRACT: Tra le moltissime costruzioni Liberty a Palermo, quest’articolo descrive Villa Antonietta, un edificio poco noto e di oscura attribuzione. Di recente è stato realizzato un’intervento di restauro; qui per brevità, si descrivono soltanto alcune questioni legate al tema del colore nel Liberty che in questa Villa sono stati riproposti con principio filologico a partire dalle preesistenze presenti a Mondello dove la Villa ha sede. SUMMERY: Of the many Liberty buildings in Palermo, this article describes Villa Antonietta, a building relatively unknown and of obscure attribution. Recently, restoration work has been undertaken. Here, for the sake of brevity is described solely a few issue…
ShRNA-mediated knock-down of CXCL8 inhibits tumor growth in colorectal liver metastasis.
2018
CXCL8 belongs to proinflammatory chemokines that are predominantly involved in neutrophil chemotaxis and degranulation. Several studies have suggested that secretion of CXCL8 from cancer cells have a profound effect on tumor microenvironment. In this study, in continuation to our previous work of understanding the global picture of invasion related genes in colorectal liver metastases, we clearly show an up-regulation of CXCL8 expression in the tumor cells at the invasion front as compared to the tumor cells in the inner parts of the tumor. Furthermore, ShRNA mediated down-regulation of CXCL8 resulted in inhibition of cell proliferation, viability and invasion in vitro and a near complete g…
Nutrition and lipidomic profile in colorectal cancers
2018
Background: Adherence to a healthy diet has been reported to be essential for the primary prevention of colorectal cancer, through a reduction of tissue inflammation, a low concentration of circulating lipoproteins and lower levels of serum cholesterol. Since an altered expression of the fatty acids pattern has been demonstrated to be a crucial event in colorectal carcinogenesis, lipidomic analysis is considered able to identify early diagnostic and prognostic biomarkers of complex diseases such as colorectal cancer. Methods: cell membrane fatty acid profile and serum lipoproteins pattern were evaluated by gas chromatography and electrophoresis method respectively. Results: There is a close…
