Building contrast-enhanced CT-based models for preoperatively predicting malignant potential and Ki67 expression of small intestine gastrointestinal stromal tumors (GISTs)

Miao-Ping Zhu et al.

Summary: CE-CT features can predict the malignant potential and high Ki67 expression in small intestine GISTs, with Ki67 index being a promising prognostic factor independent of the risk stratification system.

Predictors of Lateral Pelvic Lymph Node Metastasis in Advanced Low Rectal Cancer Treated With Neoadjuvant Chemotherapy

Tetsuo Ishizaki et al.

Summary: This retrospective study used magnetic resonance imaging to identify clinicopathological predictors of lateral pelvic lymph node metastasis in patients with advanced low rectal cancer treated with neoadjuvant chemotherapy. The short-axis diameter of lateral pelvic lymph nodes before neoadjuvant chemotherapy was identified as the only independent preoperative predictor. When the short-axis diameter is above 6.8 mm, lateral pelvic lymph node dissection may be necessary.

The importance of MRI for rectal cancer evaluation

Maria Clara Fernandes et al.

Summary: Magnetic resonance imaging (MRI) plays an increasingly important role in the management of rectal cancer. It can be used for staging, restaging, treatment selection, surgical planning, follow-up, and detection of tumor regrowth. Additionally, MRI has potential as a prognostic and predictive biomarker.

A case of an intramesenteric GIST accurately diagnosed and completely resected by PET-CT and laparoscopy after gastrectomy for gastric cancer

Manabu Sato et al.

Summary: This study presents accurate diagnosis and complete surgical resection of a gastrointestinal stromal tumor in the mesentery of the small bowel. Imaging techniques such as computed tomography and positron emission tomography-computed tomography were useful in evaluating the tumor and guiding the laparoscopic surgery. The pathological findings confirmed successful treatment outcome.
