AI Article Synopsis

  • The study discusses three cases of high-grade gliomas with O-Methylguanine-DNA Methyl-transferase (MGMT) methylation, highlighting distant recurrences despite initial successful treatment using the Stupp protocol.* -
  • All patients showed stable conditions at the original tumor site when distant recurrences occurred, suggesting effective local control, but ultimately faced poor outcomes after the metastasis.* -
  • One case involved Next Generation Sequencing (NGS), which revealed a high tumor mutational burden in the recurrent tumor, emphasizing the need to identify risk factors and correlations for more effective treatment strategies to reduce distant recurrences.*

Article Abstract

We present three cases of O-Methylguanine-DNA Methyl-transferase (MGMT) methylated high grade gliomas with distant recurrence. All three patients had a radiographic stability of original tumor site at time of distant recurrence indicating impressive local control with Stupp protocol in patients with a MGMT methylated tumors. All patients had a poor outcome after distant recurrence. For one patient Next Generation Sequencing (NGS) was available for both original and recurrent tumor and did not reveal any difference other than high tumor mutational burden in the distant recurrent tumor. Understanding risk factors of distant recurrence in MGMT methylated tumors and investigating correlations between recurrences will help plan therapeutic strategies to prevent distant recurrence and improve survival of these patients.

Austrian Breast & Colorectal Cancer Study Group (ABCSG), Vienna, Austria.

Background: The PALLAS trial investigated the addition of palbociclib to standard adjuvant endocrine therapy to reduce breast cancer recurrence. This pre-specified analysis was conducted to determine whether adjuvant palbociclib benefited patients diagnosed with lower risk stage IIA disease compared to those with higher stage disease.

Methods: PALLAS was an international, multicenter, randomized, open-label, phase III trial, representing a public-private partnership between Pfizer, the Austrian Breast Cancer Study Group, and the U.

Background: The incidence of prostate cancer is increasing in Asian countries. Although moderately hypofractionated radiotherapy is not inferior to conventional fractionated radiation according to the updated guidelines, data regarding its efficacy and safety in Taiwan are currently lacking. The aim of this study was to investigate the outcomes of prostate cancer patients treated with hypofractionated image-guided radiotherapy at a single institution in Taiwan.

Background: Prospective data comparing watch-and-wait (WW) to mandatory total mesorectal excision (TME) in patients with locally advanced rectal cancer (LARC) remains limited, as randomized control trials assessing these two treatment approaches are considered impractical. This pooled analysis of the CAO/ARO/AIO-12 and OPRA trials analyzes survival outcomes among LARC patients managed with either a selective WW or mandatory TME strategy following total neoadjuvant therapy (TNT).

Patients And Methods: The CAO/ARO/AIO-12 and OPRA trials were multicenter, phase II trials that randomized patients with stage II/III rectal cancer to receive either induction or consolidation chemotherapy as part of TNT.

Hepatocellular carcinoma (HCC) and biliary tract cancers (BTC) pose significant diagnostic and therapeutic challenges. Magnetic resonance imaging (MRI) and multiphase computed tomography (CT) have been the preferred imaging modalities for diagnosis, staging, and surveillance of patients with these malignancies. The best clinical outcomes depend on the appropriate selection of treatment options from the tools available in neo-adjuvant therapy, surgical resection, locoregional therapy, liver transplantation, and adjuvant therapy.
