Dynamic PET/CT imaging of 18F-(2S, 4R)4-fluoroglutamine in healthy volunteers and oncological patients

206Objectives: 18F-(2S, 4R)4-fluoroglutamine (18F-FGln) was developed as a PET tracer for mapping glutaminolytic tumors. The purpose of this study was to compare dynamic PET/CT imaging of 18F-FGln between healthy volunteers and oncological patients and explore the optimal imaging time in different cancer types. Methods: Two groups of subjects (13 healthy volunteers, 25 untreated cancer patients) underwent dynamic and/or static whole-body PET/CT after intravenous injection of 18F-FGln (3.7MBq per kilogram), followed by a whole body 18F-FDG/PET performed in the same week. Whole-organ volumes of interest (VOI) were drawn manually on every section of major organs/tissues in the reconstructed PET/CT images to explore the characteristic of 18F-FGln radiotracer distribution in different organs. The average standardized uptake values (SUVmean) across all scans, the coefficient of variation (CV) and the Total Activity for each organ were calculated. Same parameters were also derived for sphere/ellipsoid VOI drawn according the organs. The distribution of 18F-FDG in healthy subject group were also be evaluated as control. The Organ Level Internal Dose Assessment/Exponential Modelling (OLINDA/EXM)software was used to calculate human dosimetry based on the biodistribution of the 18F-FGln. Results: In this dynamic PET/CT imaging study of 18F-FGln, average dose was 16.90±2.13 μSv/MBq for male and 21.90±2.97 μSv/MBq for female both were below the recommended Food and Dru...

Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant genodermatosis characterized by benign cutaneous tumors (fibrofolliculomas, trichodiscomas, and acrochordons), basal lung cysts, pneumothoraces, and a 20% to 30% lifetime risk for renal cancer. There are isolated cases of other cancers in BHDS reported in the literature, including oncocytoma, rhabdomyoma, melanoma, thyroid cancer, meningioma, colon cancer, and breast cancer, but only the increased renal cancer risk has been substantiated. This is the case of a 9-year-old girl who presented with a leiomyosarcoma whose tumor genetic analysis showed FLCN c.365_372...

CONCLUSIONS: About 11 000 cancers in women and 18 000 in men may be overdiagnosed each year. Rates of overdiagnosis need to be reduced and health services should monitor emerging areas of overdiagnosis. PMID: 31858624 [PubMed - as supplied by publisher]

Authors: Brenner DR, Ruan Y, Shaw E, O'Sullivan D, Poirier AE, Heer E, Villeneuve PJ, Walter SD, Friedenreich CM, Smith L, De P Abstract BACKGROUND: Although cancer incidence over time is well documented in Canada, trends by birth cohort and age group are less well known. We analyzed age- and sex-standardized incidence trends in Canada for 16 major cancer sites and all cancers combined. METHODS: We obtained nationally representative population-based cancer incidence data in Canada between 1971 and 2015 from the National Cancer Incidence Reporting System (1969-1992) and the Canadian Cancer Registry (1992-2015). ...

Malignant mesothelioma has become the latest deadly cancer linked directly to the rescue, recovery and cleanup efforts following the 9/11 terrorist attack on New York City in 2001. The long-running threat has come to fruition. Eighteen years after Manhattan was engulfed in the asbestos-laced, toxic cloud of dust — caused primarily by the World Trade Center destruction — the first death from pleural mesothelioma attributed to 9/11 has been recorded. Nick Ursta, 52, from the southwestern part of Pennsylvania, died after a year-long battle with the rare cancer. Ursta, a construction worker and fireman by trade, w...

Yicheng Ni Cancer remains a major cause of death globally. Given its relapsing and fatal features, curing cancer seems to be something hardly possible for the majority of patients. In view of the development in cancer therapies, this article summarizes currently available cancer therapeutics and cure potential by cancer type and stage at diagnosis, based on literature and database reviews. Currently common cancer therapeutics include surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy. However, treatment with curative intent by these methods are mainly eligible for patients with localized diseas...

In this study, consequences of deficiency and overexpression of INPP4B on cellular transformation was investigated using a mouse embryonic fibroblast (MEF) model of cellular transformation. We observed that neither deficiency nor overexpression of INPP4B was sufficient to induce neoplastic transformation, alone or in combination with H-Ras V12 or E1A overexpression. However, Inpp4b-deficiency did cooperate with SV40 T-Large-mediated cellular transformation, a finding which was associated with increased phosphorylated-Akt levels. Transformation and phosphorylated-Akt levels were dampened upon overexpression of INPP4B in SV4...

President Donald Trump on Monday signed legislation that will extend the September 11th Victim Compensation Fund until 2092. During the signing ceremony at the White House, Trump was surrounding by first responders, survivors and family members of several who died in the 2001 terrorist attack on the United States. The U.S. House of Representatives and the U.S Senate voted overwhelmingly last week to approve the legislation that will provide a lifetime of assistance for victims and their families. The extension will allow the fund, first established in 2001, to pay for past and future medical claims of those effected by the...

The U.S. Senate followed the House of Representatives on Tuesday and passed legislation that will extend the September 11 Victim Compensation Fund until 2092. The legislation will fund all current and future medical claims of those effected by the 9/11 terrorist attacks on the World Trade Center in New York City, the Pentagon in Washington, and United Flight 93, which crashed in Shanksville, Pennsylvania. The extension of funding will benefit victims who may develop mesothelioma linked to the more than 400 tons of asbestos that covered the 16-acre disaster zone after the twin towers fell. According to World Trade Center R...

The Senate gallery erupted in applause from politicians and first responders on Tuesday after a 97-2 vote to extend the September 11 Victim Compensation Fund until 2092. The reauthorization will fund all current and future medical claims of those effected by the 9/11 terrorist attacks on the World Trade Center in New York City, the Pentagon in Washington, and United Flight 93, which crashed in Shanksville, Pennsylvania. The extension will allow victims and their families to file claims through 2090, but they will be paid out through 2092. The extension of funding will benefit victims who may develop mesothelioma linked to ...
