Incidence and survival of European adolescents and young adults diagnosed with sarcomas: EUROCARE-6 results.

Eur J Cancer

January 2025

Department of Medical Oncology, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Background: Epidemiological data for sarcoma in adolescents and young adults (AYAs) and across age groups are limited. We aim to: 1) update sarcoma incidence, survival, and changes over time in European AYAs; 2) provide an updated comparison of sarcoma survival in AYAs versus children and mature adults.

Methods: We calculated crude incidence rates (IR) per 100,000 European population per year from 2006 to 2013.

Background: B7-H3 or CD276 is notably overexpressed in various malignant tumor cells in humans, with extremely high expression rates. The development of a radiotracer that targets B7-H3 may provide a universal tumor-specific imaging agent and allow the noninvasive assessment of the whole-body distribution of B7-H3-expressing lesions.

Methods: We enhanced and optimized the structure of an affibody (ABY) that targets B7-H3 to create the radiolabeled radiotracer [68Ga]Ga-B7H3-BCH, and then, we conducted both foundational experiments and clinical translational studies.

Physical Activity and Quality of Life After Distal Femur Tumor Resection and Limb Salvage.

J Funct Morphol Kinesiol

December 2024

First Department of Orthopedic Surgery, School of Medicine, National and Kapodistrian University of Athens, Attikon University General Hospital, 12462 Athens, Greece.

: Distal femur tumor resection with limb salvage is a demanding procedure that offers hope for patients by preserving the limb rather than opting for amputation. While limb salvage can improve both physical function and psychological well-being, there's limited knowledge on how active patients remain afterward and how their Quality of Life (QoL) is affected, especially regarding physical activities and sports. This study investigates the quality of life of the patients through the development of motor activity, focusing on both physical and sporting activity of the above-mentioned individuals and their physical abilities to participate in activities of daily and sporting life after surgery.

Aims: Childhood cancer is a risk factor for cardiovascular diseases in later life. Retinal examination allows to non-invasively observe the vasculature of an end-organ. We observe alterations in long-term childhood cancer survivors (CCS).

DICER1-associated sarcoma is an emerging entity, defined by either somatic or germline dicer 1, ribonuclease III (DICER1) mutations and sharing characteristic morphologic features irrespective of the site of origin. In addition to the DICER1 driver mutation, concurrent genomic alterations, including tumor protein 53 (TP53) inactivation and RAS pathway activation, are frequently detected. Tumors that morphologically resemble malignant peripheral nerve sheath tumor (MPNST) have rarely been reported among DICER1 sarcomas and often pose diagnostic challenges.
