Aim: Ulcerative colitis (UC) is a known contributor to the development of colitis-associated cancer (CAC), although the exact mechanism remains to be elucidated. CAC typically presents as a flat type macroscopically and manifests histologically as mucinous carcinoma and signet ring cell carcinoma. While the relationship between disease duration and chronic inflammation has been studied, the impact of disease duration on CAC outcomes has yet to be thoroughly investigated.

To improve the prognosis of lower rectal cancer, our department has implemented total neoadjuvant therapy(TNT), which involves the preoperative administration of chemoradiotherapy combined with systemic chemotherapy. For patients who achieve a clinical complete response(cCR)with TNT, we offer the Watch-and-Wait(W & W)strategy as a treatment option. This approach allows for organ preservation and avoids immediate surgery, provided there is informed consent and strict follow-up.

Article Synopsis
  • The study focuses on using T2*-based dynamic susceptibility contrast (DSC) MR perfusion imaging to differentiate non-contrast-enhancing tumors (NETs) from vasogenic edema in glioblastomas.
  • Histological and radiological analyses revealed that NETs exhibited significantly higher cell density and blood flow parameters, while edema showed different characteristics in cerebral blood volume and mean transit time.
  • The findings suggest that parameters derived from DSC-MR imaging, particularly cerebral blood flow and mean transit time, can effectively distinguish between NETs and edema, enhancing diagnostic accuracy in glioblastoma assessment.

O6-methylguanine DNA methyltransferase promoter methylation is an important clinical biomarker of newly diagnosed glioblastoma. Previous radiological studies using dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI) perfusion have aimed to predict methylation status non-invasively in gliomas with radiological characteristics. The possibility of predicting methylation status using DSC-MRI perfusion with a radiological approach remains controversial.

  • A study analyzing the surgical treatment of aortoesophageal fistula (AEF) from 2020 to 2021 in Japan revealed that 61% of cases were secondary AEF, often arising from previous aortic surgeries.
  • Among 123 patients, the operative mortality rate was 18.7%, with significant factors contributing to mortality including postoperative complications like bleeding, stroke, and pneumonia.
  • The findings highlight the need for improved treatment strategies for AEF, as both surgical methods (open repair and TEVAR) were linked to high mortality rates and specific risk factors like dyslipidemia.
