Summary: This study conducted a systematic review and meta-analysis to evaluate the survival difference between N1h and N1p in patients with pN1M0 NSCLC. The results showed that patients with N1p metastasis had a better prognosis compared to those with N1h metastasis.

Summary: This study aimed to investigate the risk factors for poor postoperative survival and recurrence in patients with NSCLC and nodal metastasis who were surgically treated and did not receive any induction treatments. Multiple-node metastases are risk factors for both poor survival and recurrence. Additional perioperative therapies may be required, especially in patients with squamous cell carcinoma.

Summary: Lung cancer has high morbidity and mortality rates, with tumor metastasis being a significant risk factor for death. Even after complete removal of a tumor at an early stage, there is still a risk of recurrence. Lymph node micrometastasis has been found to be associated with poor prognosis, but predicting prognosis and choosing the appropriate surgical and postoperative adjuvant chemotherapy options remain challenging for clinicians.

Summary: This study evaluated the prognostic impact of lymph node characteristics on patients with therapeutic neck dissection for clinically N1 classic PTC. The results showed that the number of harvested lymph node, presence of lymph node capsular rupture, and total lymph node ratio were associated with disease persistence or recurrence.

Summary: This study evaluates the impact of PET/CT on tumor recurrence in pN0 NSCLC patients with tumor less than 4 cm, indicating that the presence of positive lymph nodes on PET/CT scans is associated with a higher risk of recurrence. Factors such as tumor SUVmax, positive lymph nodes on PET/CT, and tumor differentiation are significant in predicting tumor recurrence in this patient population.

Summary: This study found that lobar lymph node metastasis is common in patients with lung cancer, while lymph node metastasis in non-tumor-bearing segments is rare. Age, differentiation, and the status of lymph nodes found on CAT scan are independent risk factors for lobar lymph node involvement. Further investigation is needed to determine the necessity of lymph node dissection in non-tumor-bearing segments.

Summary: This study investigated adherence to guidelines regarding lymph node sampling during lobectomy for non-small cell lung cancer (NSCLC), and its association with hospital lobectomy volume. The results showed that the average rate of >= 10 lymph nodes harvested per lobectomy was higher in medium- to high-volume hospitals. However, 25% of high-volume hospitals still had a lymph node yield of <10 nodes, which may lead to inaccurate staging and have implications for adjuvant therapy and long-term survival.

Summary: This study aimed to evaluate the effect of lymph node dissection method on staging results, diagnosis of tumor metastasis, and survival rates in NSCLC patients. The results showed that it is easier to detect lymph node involvement without introducing formaldehyde, and it is recommended to perform lymph node dissection on fresh specimens.

Summary: Well-differentiated, low-grade neuroendocrine tumors (NETs) in the small bowel have a tendency to metastasize despite their slow growth. Extended regional mesenteric lymphadenectomy and the presence of mesenteric tumor deposits (MTDs) may be prognostic indicators for small bowel NETs.

Summary: This study investigated the prognostic significance of station 4R lymph node (LN) dissection in patients with right primary non-small cell lung cancer (NSCLC). The results showed that station 4R dissection improved disease-free survival (DFS) and overall survival (OS) rates in these patients. These findings suggest that station 4R dissection should be recommended as a routine procedure for right primary NSCLC patients.

Summary: This study evaluated the prognostic impact of examining the number of individual mediastinal lymph nodes (mLNs) in patients with resectable non-small cell lung cancer (NSCLC). The results showed that examining >= 3 mLNs was associated with better prognosis and lower risk of lymph node recurrence.

Summary: Endosonography is recommended for nodal staging in NSCLC patients with radiological N1. However, the diagnostic sensitivity of endosonography for detecting OMM was only 40%, indicating the need for caution in interpreting the results.

Summary: In this study, it was found that CT and SUVmax had low sensitivity but high specificity for predicting MLN metastases in solid NSCLCs with diameters between 10.1-30.0 mm. The optimal cutoff values for prediction were determined to be >18.9 mm for CT maximum short-axis diameter and >=11.7 for highest SUVmax.

Summary: By using multiplex immunofluorescence staining, the study found that tumor-infiltrating CD8+ T cells in patients with lymph node metastases in non-small cell lung cancer were in a more dysfunctional state and accompanied by an immunosuppressive microenvironment. This is associated with lymph node metastases and poor prognosis.

Summary: Lymph node ratio (LNR) is an important prognostic indicator in non-small-cell lung cancer (NSCLC), with higher LNR indicating worse prognosis. This study found that LNR and positive node category have predictive value for prognosis in stage III NSCLC patients.
