Pre-invasive lesions

Eugenio Zoni, Gabri van der Pluijm
The skeleton represents a common site of metastases for osteotropic cancers such as prostate and breast tumors and novel therapeutic targets and new markers for the monitoring of bone lesions are urgently needed. The formation of bone metastases is a complex process that starts at the level of the confined tumor and that is characterized by a dynamic crosstalk between the primary cancer and the future metastatic site, the bone. Factors released by the primary tumor contribute to prepare a fertile "soil", where a "pre-metastatic niche" is established prior to future colonization by cancer cells...

New developments in diagnostic methods, technical improvements in the surgical field, and a better understanding of the effects of epilepsy on the developing brain are contributing to the general observation that more children with epilepsy are being treated surgically. Malformations of cortical development are the most common cause of seizures in pediatric surgical candidates, and the best predictor of seizure freedom after surgery appears to be the complete removal of the epileptogenic lesion. To achieve this goal in challenging cases, such as magnetic resonance imaging-negative or multifocal lesions, a staged approach with pre- and/or post-resective invasive electroencephalography monitoring has increasingly been used at a number of centers...

Prevention of progression to invasive carcinoma in patients with a premalignant endometrial lesion using longterm treatment with levonorgestrel (LNG) releasing intrauterine systems (IUS) remains controversial, especially when manifest cellular atypia has been found in the endometrial biopsy specimen. We present a case of a 44-year old premenopausal woman with a premalignant uterine polyp who declined hysterectomy and was followed-up for more than 12 years after the first LNG-IUS was inserted. Endometrial atrophy installed, no pathology was detected and hysterectomy was thereby successfully avoided...

Breast cancer biomarkers that can precisely predict the risk of progression of non-invasive ductal carcinoma in situ (DCIS) lesions to invasive disease are lacking. The identification of molecular alterations that occur during the invasion process is crucial for the discovery of drivers of transition to invasive disease and, consequently, biomarkers with clinical utility. In this study, we explored differences in gene expression in mammary epithelial cells before and after the morphological manifestation of invasion, i...

BACKGROUND: The current management of pancreatic mucinous cystic neoplasms (MCN) is defined by the consensus European, International Association of Pancreatology and American College of Gastroenterology guidelines. However, the criterion for surgical resection remains uncertain and differs between these guidelines. Therefore through this systematic review of the existing literature we aimed to better define the natural history and prognosis of these lesions, in order to clarify recommendations for future management...

The past decade has seen the development of technologies that have revolutionized prenatal genetic testing; that is, genetic testing from conception until birth. Genome-wide single-cell arrays and high-throughput sequencing analyses are dramatically increasing our ability to detect embryonic and fetal genetic lesions, and have substantially improved embryo selection for in vitro fertilization (IVF). Moreover, both invasive and non-invasive mutation scanning of the genome are helping to identify the genetic causes of prenatal developmental disorders...

Epilepsy surgery is aimed to remove the brain tissues that are indispensable for generating patient's epileptic seizures. There are two purposes in the pre-operative evaluation: localization of the epileptogenic zone and localization of function. Surgery is planned to remove possible epileptogenic zone while preserving functional area. Since no single diagnostic modality is superior to others in identifying and localizing the epileptogenic zone, multiple non-invasive evaluations are performed to estimate the location of the epileptogenic zone after concordance between evaluations...

Intraductal carcinoma of the prostate gland (IDC-P) is a newly recognized tumor entity, now accepted as part of the 2016 World Health Organization (WHO) classification of tumours of the prostate gland.(1) It is defined as a lumen-spanning proliferation of atypical prostatic cells within pre-existing ducts, exceeding the characteristics of the precursor lesion high grade PIN. IDC-P is generally associated with aggressive high-volume, high-grade and high-stage invasive prostate cancer. This may therefore represent extension of the latter along benign ducts of the prostate gland...

BACKGROUND: Mammography screening is a cost-efficient modality with high sensitivity for detecting impalpable cancer with microcalcifications, and results in reduced mortality rates. However, the probability of finding microcalcifications without associated cancerous masses varies. We retrospectively evaluated the diagnosis and cancer probability of the non-mass screened microcalcifications by dual-energy contrast-enhanced spectral mammography (DE-CESM). PATIENTS AND METHODS: With ethical approval from our hospital, we enrolled the cases of DE-CESM for analysis under the following inclusion criteria: (1) referrals due to screened BI-RADS 4 microcalcifications; (2) having DE-CESM prior to stereotactic biopsy; (3) no associated mass found by sonography and physical examination; and (4) pathology-based diagnosis using stereotactic vacuum-assisted breast biopsy...

PURPOSE: Once lung cancer is detected due to clinical symptoms or by being visible on chest X-ray, it is usually high stage and non-operable. In order to improve mortality rates in lung cancer, low-dose CT (LDCT) screening of "high risk" individuals is gaining popularity. However, the rate of malignancy in LDCT detected sub-centimetre lung nodules is not clear. We aimed to analyze surgically resected specimens in this patient group to explore cost effectiveness and recommendations for clinical management of these nodules...

BACKGROUND AND STUDY AIMS: Endoscopic submucosal dissection (ESD) carries significant advantages over endoscopic mucosal resection. As such, ESD is an established therapy for esophageal squamous cell carcinoma but there are only limited data on ESD as therapy for Barrett's esophagus (BE). Thus, we prospectively evaluated the outcomes of ESD in patients with BE with high-grade dysplasia (HGD) and early esophageal adenocarcinoma (EAC) performed in a Western center. PATIENTS AND METHODS: This is a prospective cohort study...
