Early Gastric Cancer Sentinel Lymph Node Metastasis Analysis from a Tertiary Hospital

238 patients with early gastric cancer underwent sentinel lymph node biopsy and pelvic dissection, with 30 identified as having lymph node metastasis. The data, authored by Huiliang Zhang and last updated in April 2026, originates from a retrospective analysis of prospectively collected data at a tertiary hospital. It focuses on the failure rate of intraoperative frozen section identification and the incidence of metastasis in non-sentinel lymph nodes.

Use Cases

• Assessing the accuracy of intraoperative frozen section pathology for detecting macrometastasis based on the study's primary outcome variables.
• Modeling the risk of non-sentinel lymph node metastasis when sentinel nodes are tumor-positive, based on the reported 8.3% incidence.
• Evaluating long-term outcomes for patients with micrometastasis identified only in permanent sections, based on the follow-up recurrence data mentioned.
• Comparing diagnostic efficacy of single-section hematoxylin and eosin staining versus more detailed methods as suggested by the study conclusions.

Strengths

• Data is derived from a clinical study involving 238 patients, providing a substantive cohort size.
• Includes specific outcome metrics such as a failure rate and an 8.3% incidence of non-sentinel node metastasis.
• Published under a permissive CC-BY-4.0 license, allowing for reuse and analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• The dataset is very small at 110.5 KB, indicating limited scope and likely summary-level data.
