Pleomorphic xanthoastrocytoma (PXA) is a rare, low-grade glioma that frequently occurs in pediatric patients. ⋯ PXA in adults PXA may present features distinct from pediatric PXA. Anaplastic features and BRAF mutation may potentially identify specific subgroups with distinct prognoses.

Multicenter Study
Effect of adjuvant chemotherapy on recurrence-free survival varies by neo-adjuvant treatment in patients with stage III rectal cancer.
Adjuvant chemotherapy still is a controversial therapy for rectal cancer patients. The aim of this study was to analyze the effect of adjuvant chemotherapy on recurrence-free survival (RFS) for patients with stage III rectal cancer treated in clinical practice, taking into account which neo-adjuvant treatment patients received. ⋯ Among patients with stage III rectal cancer, the effect of adjuvant chemotherapy on RFS seems to vary by neo-adjuvant treatment.

Multicenter Study
French current management and oncological results of locally recurrent rectal cancer.
There is a significant worldwide variation in practice regarding the criteria for operative intervention and overall management in patients with locally recurrent rectal cancer (LRRC). A survival benefit has been described for patients with clear resection margins in patients undergoing surgery for LRRC which is seen as an important surgical quality indicator. ⋯ Our data is in accordance with the literature except the rate of extended resection procedures. This underlines the selective character of operative indications for LRRC in France as well as the care variability and the absence of optimal clinical pathway regarding these patients.

The combination of advances in surgical technique and neoadjuvant therapy for rectal cancer has resulted in more patients undergoing sphincter-preserving surgery. Unfortunately, numerous patients subsequently experience bowel dysfunction, and may suffer from lifelong severe disability with major impact on their quality of life. The aim of the present study was to investigate whether the risk of severe LARS in patients was associated with the length of remnant rectum. ⋯ Both the length of remnant rectum and preoperative chemoradiotherapy had a major impact on the severity of bowel dysfunction after restorative rectal cancer surgery. No functional benefit from an irradiated rectal remnant was observed.
