[Borderlines and malignant phyllodes tumors of the breast: From the anatomopathological challenge to the standard of care].

Phyllodes tumors, borderline (BPT) and malignant (MPT), represent a rare group of fibroepithelial breast tumors. Due to their rarity, their treatment remains poorly codified. The precise incidence of these tumors remains unknown.

Alveolar soft part sarcomas in young patients: The French national NETSARC+ network experience.

Background And Aims: Alveolar soft part sarcoma (ASPS) is an ultra-rare chemo-resistant sarcoma in children, occurring preferentially in young adults. We aimed to describe and compare its clinical presentation and behaviour in children and young adults to determine whether the same therapeutic strategy should be addressed for both populations.

Methods: National retrospective multicentre study of children (0-18 years) vs.

Improved nationwide survival of sarcoma patients with a network of reference centers.

Background: We investigated the impact of the implementation of a network of reference centers for sarcomas (NETSARC) on the care and survival of sarcoma patients in France since 2010.

Patients And Methods: NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized multidisciplinary tumor boards (MDTBs), funded by the French National Cancer Institute (INCa) since 2010.

[Uterin sarcoma, high-grade stroma, indifferenciated, referential].

High-grade endometrial stromal sarcoma (HGESS) and uterine undifferentiated sarcoma (UUS) are rare uterine malignancies arising from mesenchymal endometrial cells. They are characterized by aggressive behavior and poor prognosis. Median age of diagnostic is 55years.

Prognostic Value of the Lung Immune Prognosis Index Score for Patients Treated with Immune Checkpoint Inhibitors for Advanced or Metastatic Urinary Tract Carcinoma.

Few prognostic factors have been identified in patients with metastatic urothelial carcinoma (mUC) treated with immune checkpoint inhibitors (ICIs). The Lung Immune Prognostic Index (LIPI) was associated with clinical outcomes for ICIs in several tumor types. We aim to assess the value of the LIPI in patients with mUC treated with ICIs.
