Carbon-ion radiotherapy alone vs. standard dose photon radiation with carbon-ion radiotherapy boost for high-grade gliomas: a retrospective study.

Background: This study aimed to compare the survival outcome and side effects in patients with primary high-grade glioma (HGG) who received carbon ion radiotherapy (CIRT) alone or as a boost strategy after photon radiation (photon + CIRT).

Patients And Methods: Thirty-four (34) patients with histologically confirmed HGG and received CIRT alone or Photon + CIRT with concurrent temozolomide between 2020.03-2023.

CT-guided radioactive seed implantation for recurrent rectal carcinoma after multiple therapy.

The recurrent carcinoma has been difficult to manage after surgery and radiotherapy, extensive resection of locally recurrent rectal cancer is associated with significant morbidity and mortality. Re-irradiation, even in combination with chemotherapy has shown very short survival. We assess the feasibility and efficacy of CT-guided interstitial permanent brachytherapy with (125)I or (103)Pd seeds for recurrent rectal cancer after multiple treatments.

Interstitial permanent implantation of 125I seeds as salvage therapy for re-recurrent rectal carcinoma.

Purpose: To assess the feasibility, efficacy, and morbidity of (125)I seeds interstitial permanent implant as salvage therapy for re-recurrent rectal cancer.

Methods And Materials: From September 2003 to October 2007, (125)I seeds implant procedures were performed under CT or ultrasound guidance for thirteen patients with locally re-recurrent rectal carcinoma. The minimal peripheral doses (MPD) of (125)I seeds implanted ranged from 120 to 160 Gy, with a median MPD of 140 Gy to total decay.
