### Title

Meta-analysis findings show that neoadjuvant imatinib achieves high 1-year, 3-year, and 5-year overall survival rates of 100%, 94%, and 88%, respectively. Patients with gastric and rectal tumors benefit most with an 8-month treatment duration. Additionally, mutational analysis can aid in treatment decision-making. Effective outcomes include an 89% R0 resection rate and a 67% disease response […]

MRI Predicts Histological Grades in Soft Tissue Sarcomas

MRI effectively predicts histological grades of soft tissue sarcomas. Peritumoral high-intensity T2-weighted signals and peritumoral postcontrast enhancement are valuable indicators of high-grade tumors. The study’s findings highlight the importance of MRI in treatment decision-making for sarcoma patients, with each score point increment doubling the chance of high-grade tumors.

Lymph Node Staging Systems and Prognosis of Colorectal Neuroendocrine Neoplasms

Colorectal neuroendocrine neoplasms prognosis in surgical treatment can be predicted by lymph node staging systems like LNR, PLN, and LODDS. A cohort study of 895 patients showed significant predictive values for mortality. After adjusting confounders, these systems were linked with patient outcomes, proving their effectiveness in assessing prognosis. This study highlights the importance of lymph […]

Outcomes of Robotic Radical Surgery for Rectal GIST

Favorable short-term and long-term outcomes were observed in patients undergoing robotic radical surgery for rectal gastrointestinal stromal tumor (GIST), with 100% 5-year overall survival and recurrence-free survival rates. The majority of patients had negative surgical margins, underwent sphincter-preserving surgery, and experienced low postoperative complication rates, highlighting the potential utility of robotic surgery for this condition. […]

Endoscopic Resection for Intermediate- or High-Risk Gastric Gastrointestinal Stromal Tumors

Endoscopic resection is a safe and effective method for treating intermediate- or high-risk gastric small gastrointestinal stromal tumors, with a 5-year overall survival rate of 97.4%. Close follow-up is necessary for these patients, but there were no recurrences or metastases observed, even among those with R1 resections. This approach allows for a wait-and-see strategy before […]

Long-term Efficacy of Imatinib Combined with Hepatic Resection for GIST Liver Metastases

Imatinib combined with hepatic resection significantly improves overall survival in patients with gastrointestinal stromal tumor liver metastases compared to imatinib monotherapy. Achieving no evidence of disease status through surgical intervention leads to prolonged overall survival, liver-specific progression-free survival, and progression-free survival. Age ≤60 years and combination therapy were independently associated with better outcomes. Journal Article […]

Computed Tomography Radiogenomics: Predicting Molecular Subtypes in Gastric Stromal Tumors

A combined model integrating clinical and contrast-enhanced computed tomography (CE-CT) features accurately predicts specific genetic mutations in gastrointestinal stromal tumors (GISTs). Researchers developed three models from data from 231 GIST patients, with the best model achieving high accuracy in predicting molecular subtypes. In the training cohort, the area under the curve (AUC) values indicated significant […]

Benefit of Surgical Cytoreduction for Patients with Small Intestinal Neuroendocrine Tumors Metastatic to the Liver and Peritoneum

Complete cytoreduction can significantly improve survival and relieve symptoms in patients with small intestinal neuroendocrine tumors metastatic to the liver and peritoneum. Despite initial controversies, achieving complete cytoreduction yielded comparable outcomes in patients with isolated liver metastases and those with liver and peritoneal metastases. Aggressive surgical cytoreduction should be considered even in the presence of […]

Comparing Gastrointestinal Stromal Tumor Outcomes Between Geriatric and Non-Geriatric Patients

Population-based analysis shows lower overall 5-year survival rates in geriatric gastrointestinal stromal tumor patients compared to non-geriatric patients. Surgery significantly improves survival rates in both groups, with geriatric patients having higher hazard death ratio. Clinical management for geriatric patients may benefit from large prospective studies. Journal Article by Singh A, Chitti B (…) Parashar B […]

Effectiveness and Safety of Endoscopic Resection for Gastric Gastrointestinal Stromal Tumors

Researchers investigated the efficacy and safety of endoscopic resection (ER) for gastric gastrointestinal stromal tumors (GISTs) originating from the muscularis propria (MP). The study included 233 patients who underwent ER, with a median tumor size of 12 mm. The complete resection rate was 93.1%, with complications occurring in 4.7% of cases, including perioperative perforations (1.7%) […]
