Frontal recurrence of medulloblastoma five years after excision and craniospinal irradiation

Craniospinal Irradiation in Medulloblastoma using High Energy Medical Linear Accelerator: an Innovative Approach to Planning Technique

Background: Craniospinal irradiation (CSI) of medulloblastoma poses technological challenges due to the involvement of large treatment volume. Commonly, the whole treatment length is covered with two different isocentric plans in which the junction is shifted after every five fractions to overcome the possibility of hot and cold spot.Objective: This study aims to evaluate dosimetrically and cli...

A review of dosimetric and toxicity modeling of proton versus photon craniospinal irradiation for pediatrics medulloblastoma.

BACKGROUND Craniospinal irradiation (CSI) is the standard radiation therapy treatment for medulloblastoma. Conventional CSI photon therapy (Photon-CSI) delivers significant dose to surrounding normal tissue (NT). Research into pediatric CSI with proton therapy (Proton-CSI) has increased, with the aim of exploiting the potential to reduce NT dose and associated post-treatment complications. This...

P-211: Recurrence Rate of Ovarian Endometriomas after A Laparoscopic Excision

Background: Endometrioma is a common cause of gynecologic morbidity and the most common benign ovarian cysts are found at surgery. One of the most troubling aspects of treating endometrioma with laparoscopic excision is disease recurrence after surgery. Present study was conducted to evaluate risk factors for the recurrence of endometrioma after first laparoscopic excision. Materials and Method...

Adjuvant chemotherapy after reduced craniospinal irradiation dose in children with average-risk medulloblastoma: a 5-year follow-up study.

PURPOSE This study was undertaken to determine the effect of adjuvant chemotherapy combined with reduced-dose craniospinal irradiation (CSI) on survival and neurocognitive sequelae of radiotherapy (RT) in patients with average- risk medulloblastoma above the age of 3 years. METHODS Thirty-three children between 3 and 10 years of age with average-risk medulloblastoma were treated with postoper...
