AI Article Synopsis
- Patients with stage I gastric cancer have a risk of recurrence despite good surgical outcomes, making it essential to identify prognostic factors.
- A study analyzed 1,880 patients from 1985 to 2000, finding depth of invasion, lymph node metastasis, lymphovascular invasion, and advanced age significantly affected prognosis.
- Results showed that T2N0 patients with severe lymphovascular invasion might benefit from adjuvant chemotherapy based on differing 5-year survival rates across stages.
Article Abstract
Background: Patients with stage I gastric cancer often suffer from tumor recurrence despite a generally favorable operative outcome. It is therefore important to determine the prognostic factors in order to improve such outcomes.
Methods: Between April 1985 and March 2000, a total of 1,880 patients with histologically proven stage I gastric cancer were included in this study. Operative outcomes (survival time, prognostic factors, pattern of recurrence) were evaluated in these patients.
Results: Multivariate analysis in patients with all stage I gastric cancer revealed that depth of invasion, lymph node metastasis, and lymphovascular invasion independently influenced prognosis. Moreover, advanced age was selected as an independent prognostic factor in patients with stage IA, and lymphovascular invasion in patients with stage IB gastric cancer by multivariate analyses. The 5-year survival rates in stage T1N1 patients with moderate to severe lymphovascular invasion, T2N0 with moderate to severe lymphovascular invasion, and II were 95.1%, 83.5%, and 76.9%, respectively. There was a significant difference in survival time between stage T1N1 and II (P = .0189) but not between stage T1N1 and T2N0 or stage T2N0 and II.
Conclusion: T2N0 gastric cancer patients with moderate to severe lymphovascular invasion may be suitable candidates for adjuvant chemotherapy.

A novel MRI-based radiomics for preoperative prediction of lymphovascular invasion in rectal cancer.
Abdom Radiol (NY)
January 2025
Department of Radiology, Taizhou Municipal Hospital, Taizhou, Zhejiang, China.
Background: To develop and validate a clinical-radiomics model for preoperative prediction of lymphovascular invasion (LVI) in rectal cancer.
Methods: This retrospective study included data from 239 patients with pathologically confirmed rectal adenocarcinoma from two centers, all of whom underwent MRI examinations. Cases from the first center (n = 189) were randomly divided into a training set and an internal validation set at a 7:3 ratio, while cases from the second center (n = 50) constituted the external validation set.
Local excision for T1 rectal cancer: A population-based study of practice patterns and oncological outcomes.

Division of General Surgery, Department of Surgery, Queen's University, Kingston, Ontario, Canada.
Aim: Local excision (LE) for T1 rectal cancer may be recommended in those with low-risk disease, while resection is typically recommended in those with a high risk of luminal recurrence or lymph node metastasis. The aim of this work was to compare survival between resection and LE.
Method: This was a population-based retrospective cohort study set in the Canadian province of Ontario.

Background: Few studies have explored the genetic changes and clinicopathological features of stage II/III gastric cancer (GC) patients with no tumor recurrence, early recurrence, or late recurrence after curative surgery.
Methods: In this study, 376 patients who underwent curative surgery for stage II/III GC were analyzed. The clinical and genetic features of patients with no recurrence, early recurrence (<2 years), and late recurrence (≥2 years) were compared.
Preoperative comprehensive risk estimation for axillary lymph node metastasis in breast cancer: development and verification of a network-based prediction model.

Department of Thyroid and Breast Diagnosis and Treatment Center, Weifang Hospital of Traditional Chinese Medicine, Shandong Second Medical University, No. 1055 Weizhou Road, Kuiwen District, Weifang City, 261000, Shandong Province, China.
To prevent the overaggressive treatment of axillary lymph nodes (ALNs) in breast cancer, it is necessary to develop a convenient analysis method that accurately and comprehensively reflects whether ALNs are metastatic or nonmetastatic. We retrospectively analyzed data from patients who underwent surgery for breast cancer at the Weifang Hospital of Traditional Chinese Medicine between January 2019 and June 2023. Binary logistic regression analysis was used to predict the metastasis status of ALNs.
