Concepts to Target MYC in Pancreatic Cancer.
2016
Abstract Current data suggest that MYC is an important signaling hub and driver in pancreatic ductal adenocarcinoma (PDAC), a tumor entity with a strikingly poor prognosis. No targeted therapies with a meaningful clinical impact were successfully developed against PDAC so far. This points to the need to establish novel concepts targeting the relevant drivers of PDAC, like KRAS or MYC. Here, we discuss recent developments of direct or indirect MYC inhibitors and their potential mode of action in PDAC. Mol Cancer Ther; 15(8); 1792–8. ©2016 AACR.
Análisis de biopsias líquidas para el diagnóstico del cáncer: revisión sistemática
2020
The incidence of cancer has increased in recent years, especially in those over 65 years of age, posing a major health problem. Many tumours have a poor prognosis because they are diagnosed at very advanced stages. It is therefore especially important to incorporate liquid biopsy into clinical practice as a method for detecting tumours at very early stages. A systematic review was conducted, with the main objective of analysing the available literature on the use of liquid biopsy in the early diagnosis of cancer, and as a secondary objective, to determine the types of tumours that can be diagnosed early by liquid biopsy and the available biomarkers. The results indicate a lack of agreement …
Target Therapies for Uterine Carcinosarcomas: Current Evidence and Future Perspectives
2017
Carcinosarcomas (CS) in gynecology are very infrequent and represent only 2–5% of uterine cancers. Despite surgical cytoreduction and subsequent chemotherapy being the primary treatment for uterine CS, the overall five-year survival rate is 30 ± 9% and recurrence is extremely common (50–80%). Due to the poor prognosis of CS, new strategies have been developed in the last few decades, targeting known dysfunctional molecular pathways for immunotherapy. In this paper, we aimed to gather the available evidence on the latest therapies for the treatment of CS. We performed a systematic review using the terms “uterine carcinosarcoma”, “uterine Malignant Mixed Müllerian Tumors”, “target therapies”,…
Mitochondrial DNA Replacement Techniques to Prevent Human Mitochondrial Diseases.
2021
Background: Mitochondrial DNA (mtDNA) diseases are a group of maternally inherited genetic disorders caused by a lack of energy production. Currently, mtDNA diseases have a poor prognosis and no known cure. The chance to have unaffected offspring with a genetic link is important for the affected families, and mitochondrial replacement techniques (MRTs) allow them to do so. MRTs consist of transferring the nuclear DNA from an oocyte with pathogenic mtDNA to an enucleated donor oocyte without pathogenic mtDNA. This paper aims to determine the efficacy, associated risks, and main ethical and legal issues related to MRTs. Methods: A bibliographic review was performed on the MEDLINE and Web of S…
MicroRNAs expression associated with aggressive clinicopathological features and poor prognosis in primary cutaneous melanomas
2020
Several studies have focused on identifying microRNAs involved in the pathogenesis of melanoma. However, its association with clinicopathological features has been scarcely addressed. The aim of this study is to identify microRNAs expression profiles related to aggressive clinicopathological and molecular features, and to analyze the association with melanoma survival. A retrospective and observational study was performed in a series of 179 formalin-fixed paraffin embedded primary cutaneous melanomas. First, a screening analysis on a discovery set (n = 22) using miRNA gene chip array (Affymetrix, Santa Clara, California, USA) was performed. Differentially expressed microRNAs were detected e…
Distribution and risk of the second discordant primary cancers combined after a specific first primary cancer in German and Swedish cancer registries
2015
We aimed at investigating the distribution and risk of all second discordant primary cancers (SDPCs) after a specific first primary cancer in Germany and Sweden to provide etiological understanding of SDPCs and insight into their incidence rates and recording practices. Among 1,537,004 survivors of first primary cancers in Germany and 588,103 in Sweden, overall 80,162 and 32,544 SDPCs were recorded, respectively. Standardized incidence ratios (SIRs) of all SDPCs were elevated at levels between 1.1 and 2.1 after 23 (out of overall 29) cancers in Germany and at levels between 1.1 and 1.6 after 24 cancers in Sweden, and among them, elevated SIRs were found after 19 cancers in both populations.…
Low incidence but poor prognosis of complicated coeliac disease: A retrospective multicentre study.
2013
Abstract Background Coeliac disease is a chronic enteropathy characterized by an increased mortality caused by its complications, mainly refractory coeliac disease, small bowel carcinoma and abdominal lymphoma. Aim of the study was to study the epidemiology of complications in patients with coeliac disease. Methods Retrospective multicenter case–control study based on collection of clinical and laboratory data. The incidence of complicated coeliac disease was studied among coeliac patients directly diagnosed in four Italian centres. Patients referred to these centres after a diagnosis of coeliac disease and/or complicated coeliac disease in other hospitals were therefore excluded. Results B…
Conservative Surgery of Renal Carcinoma: The EIRSS Experience
1981
Summary— Seventy-two patients with renal carcinoma (RC) in a solitary kidney or bilateral synchronous tumours underwent parenchyma-sparing excision of their neoplasms. This was performed in situin 51 and extracorporeally in 21 kidneys, with a complication rate respectively of 1 7 and 43%. The 5-year survival rates were 78% for unilateral disease, 48% for bilateral synchronous and 38% for bilateral asynchronous disease. Survival correlated with Pcategory, grade and diameter of the tumour. Vascular invasion and spindle cells indicated a poor prognosis; the position of the tumour, oncocytic elements, calcification, lymphocytic infiltration or the predominance of clear cell or granular cells di…
Survival and prognostic factors in patients with oral squamous cell carcinoma
2020
Background This study aimed to evaluate sociodemographic and clinical factors influencing overall survival (OS) in patients with oral squamous cell carcinoma (OSCC). Material and Methods Medical charts of 547 patients with OSCC from a public hospital in northeastern Brazil seen between 1999 and 2013 were evaluated. Survival analysis was performed using the Kaplan-Meier method. The influence of age, sex, ethnicity, clinical stage, anatomical location, type of treatment, and comorbidities on the patients’ prognosis was evaluated. Cox proportional hazards regression model was used to identify independent prognostic factors. Results The 5-year OS was 39%. Multivariate analysis showed that age <…
Combined use of uterine artery embolization and local methotrexate injection in interstitial ectopic pregnancies with poor prognosis.
2009
Objective To report three cases of interstitial pregnancies treated successfully by combining uterine artery embolization (UAE) and ultrasound-guided local administration of methotrexate (MTX); and to assess the effect of UAE on ovarian reserve by prospectively measuring serum antimullerian hormone (AMH) levels. Design Case report. Setting Departments of obstetrics and gynecology and radiology of a university hospital. Patient(s) Three patients with interstitial pregnancy. Treatment with multiple IM injections of MTX had failed in cases 1 and 3. Case 2 presented high initial serum β-hCG levels (93,563 mIU/mL), suggesting the presence of a substantial amount of trophoblastic tissue. Interven…
