Background: Current risk factors for lymph node metastasis in early gastric cancer have been primarily determined in Asian countries; however their applicability to Western nations is under discussion. The aim of our study was to identify risk factors associated with lymph node metastasis in Western cohort patients from the Eastern European country - Lithuania.

Methods: A total of 218 patients who underwent open gastrectomy for early gastric cancer were included in this retrospective study. After histolopathological examination, risk factors for lymph node metastasis were evaluated. Overall survival was evaluated and factors associated with long-term outcomes were analyzed.

Results: Lymph node metastases were present in 19.7% of early gastric cancer cases. The rates were 5/99 (4.95%) for pT1a tumors and 38/119 (31.9%) for pT1b tumors. Submucosal tumor invasion, lymphovascular invasion, and high grade tumor differentiation were identified as independent risk factors for lymph node metastasis. Submucosal tumor invasion and lymphovascular invasion were also associated with worse 5-year survival results.

Conclusion: Our study established submucosal tumor invasion, lymphovascular invasion, and high grade tumor differentiation as risk factors for lymph node metastasis.

To evaluate the clinical value of multi-slice spiral CT in preoperative TNN staging and postoperative recurrence and metastasis of colon carcinoma, and to provide evidence for the reliability of CT in the diagnosis of colon carcinoma METHODS: 89 patients with colon carcinoma diagnosed pathologically in our hospital from July 2020 to April 2023 were selected retrospectively. The preoperative TNN staging and postoperative recurrence and metastasis were monitored by 64 row 128 layer spiral CT. The diagnostic coincidence rate, TNM staging coincidence rate and postoperative recurrent TNM staging accuracy were evaluated according to the pathological diagnosis RESULTS: The diagnostic coincidence rate of multi-slice spiral CT was 97.

Purpose: Total marrow (lymph-node) irradiation (TMI/TMLI) is a radiotherapy technique irradiating the whole body of a patient. The limited couch travel range in modern linacs (130-150 cm) forces to split the TMI/TMLI delivery into two plans with opposite orientation. A dedicated field junction is necessary to achieve satisfactory target coverage in the overlapping region of the two plans.

Antigen affinity and site of immunization dictate B cell recall responses.

Department of Microbiology, Tumor and Cell Biology, Division of Virology and Immunology, Karolinska Institutet, 171 65 Solna, Sweden. Electronic address:

Protective antibodies against HIV-1 require unusually high levels of somatic mutations introduced in germinal centers (GCs). To achieve this, a sequential vaccination approach was proposed. Using HIV-1 antibody knockin mice with fate-mapping genes, we examined if antigen affinity affects the outcome of B cell recall responses.

Single-Injection Composite Tracer Achieves Intraoperative Dual-Tracing and Precise Localization of Sentinel Lymph Nodes.

The use of dual-tracer contrast agents in clinical applications, such as sentinel lymph node (SLN) identification, offers significant advantages including enhanced accuracy, sensitivity, as well as comprehensive and multimodal visualization. In the current clinical practice, SLNs are typically marked prior to surgical resection by multiple and sequential injections of two tracers, the radioactive tracer and methylene blue (MB) dye. This imposes physical and psychological burden on patients and medical staff.
