To investigate and compare the prevalence of nodal metastases in individual lymph node stations between different T-stages of gastric cancer, highlighting the clinical significance of tailored approaches.
Key Findings:
Overall prevalence of LN metastases in T1 tumors is 8%-31%; in T2-T4 tumors, it is 45%-90%. This suggests a need for tailored surgical approaches.
The necessity for a tailored approach based on gastric T-stage is highlighted.
D1 lymphadenectomy is recommended for T1a tumors and well-differentiated T1b tumors < 1.5 cm.
Interpretation:
The findings suggest that the extent of lymphadenectomy should be tailored according to the T-stage of gastric cancer to optimize outcomes and minimize recurrence, emphasizing the clinical implications.
Limitations:
The studies included were conducted between 1989 and 2014, potentially limiting the applicability of findings to current practices.
Exclusion of systematic reviews and case series may have omitted relevant data, and potential biases in study selection should be considered.
Conclusion:
A more extensive lymphadenectomy may improve survival rates, but the balance between morbidity and adequate cancer control must be carefully considered, especially for early-stage tumors, to ensure optimal patient outcomes.
