Article Abstract
Background: The aim of this study was to evaluate the prognostic importance of the metastatic lymph node ratio for stage III colon cancer patients and to find a cut-off value at which the overall survival and disease-free survival change.
Material/methods: Patients with pathological stage III colon cancer were retrospectively evaluated for: age; preoperative values of Crp, Cea, Ca 19-9, and Afp; pathologic situation of vascular, perineural, lymphatic, and serosal involvement; and metastatic lymph node ratio values were calculated.
Results: The study included 58 stage III colon cancer patients: 20 (34.5%) females and 38 (65.5%) males were involved in the study. Multivariate analysis was applied to the following variables to evaluate significance for overall survival and disease-free survival: age, Crp, Cea, perineural invasion, and metastatic lymph node ratio. The metastatic lymph node ratio (<0.25 or ≥0.25) is the only independent variable significant for overall and disease-free survival.
Conclusions: Metastatic lymph node ratio is an ideal prognostic marker for stage III colon cancer patients, and 0.25 is the cut-off value for prognosis.

This study explores effective treatment methods for chronic secondary lymphedema after radical cervical cancer surgery combined with pelvic lymphadenectomy. In cases where conservative treatment was ineffective, we investigated whether multiple injections of indocyanine green can effectively improve the outcomes of lymphatic-venous anastomosis under microscopy. Preoperative lymphatic imaging was used to localize functional vessels, guiding distal left lower limb lymphatic reconstruction.

Background: To compare the short-term outcomes of robotic abdominoperineal resection with laparoscopic abdominoperineal resection in patients with rectal cancer.
Methods: We searched PubMed, Embase, and Cochrane through March 2024 following PRISMA guidelines (PROSPERO number: CRD42024520671). Randomized controlled trials and nonrandomized studies comparing short-term outcomes between the 2 approaches were selected.

Nonsmall cell lung cancer (NSCLC) with SMARCA4 deficiency represents a rare subset of lung tumors characterized by early metastasis, poor response to chemotherapy, and unfavorable prognosis. Established therapy strategies for SMARCA4-deficient NSCLC remain elusive. While immune checkpoint inhibitors have been proposed as a potential solution, their efficacy remains uncertain.

Aim And Background: This study investigates the impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in patients undergoing radical surgery for right-sided colon cancer. Given that postoperative diarrhea can significantly affect the quality of life, we examined whether dissection boundaries influence these outcomes.
Methods: This was a prospective, randomized controlled trial conducted at a high-volume tertiary hospital.

Introduction: Metastatic colorectal cancer (mCRC) exhibits significant heterogeneity in molecular profiles, influencing treatment response and patient outcomes. Mutations in v-raf murine sarcoma viral oncogene homolog B1 () and rat sarcoma () family genes are commonly observed in mCRC. Though originally thought to be mutually exclusive, recent data have shown that patients may present with concomitant and mutations, posing unique challenges and implications for clinical management.
