Background: The objective of the current study was to investigate the clinical significance of the suprasternal space lymph node (SSLN) in pathological node-positive (pN+) papillary thyroid carcinoma (PTC) patients.
Method: One hundred and forty patients with pN + PTC who underwent neck dissection were enrolled into this study. SSLN was resected and used as a specimen to investigate the relationship of SSLN with several clinicopathological parameters.
Results: The metastasis rate of SSLN was 20.7%. On univariate analysis, we found that SSLN metastasis was significantly associated with primary cancer site (inferior portion), strap muscle invasion, level III metastasis, Level IV metastasis and lymph node metastasis between sternocleidomastoid and sternohyoid muscles. On multivariate analysis, primary cancer site (inferior portion), strap muscle invasion, Level IV metastasis and lymph node metastasis between sternocleidomastoid and sternohyoid muscles were independent risk factors for SSLN metastasis of PTC.
Conclusion: For pN + PTC patients, special attention should be paid to the issue of SSLN metastasis.

Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) of the colon is rare with a poor prognosis. Since the first description of a mixed neoplasm 100 years ago, the nomenclature has evolved, most recently with the 2022 World Health Organization (WHO) classification system. We describe our experience of a case of locoregionally advanced MiNEN of the descending colon treated with curative laparoscopic resection and adjuvant chemotherapy.

Sarcoid-like reaction is an immunological reaction that can affect lymph nodes and organs but does not meet the diagnostic criteria for systemic sarcoidosis. Anti-CD20 auto-antibodies have been reported to be responsible for such reactions. There are several reported associations between Chronic lymphocytic leukaemia (CLL), Amyotrophic lateral sclerosis (ALS) and Sarcoid-like reactions (SLR).

Background: Lung cancer is a leading cause of morbidity and mortality globally. Despite advances in targeted and immunotherapies, overall survival (OS) rates remain suboptimal. Cyclin-A2 (CCNA2), known for its upregulation in various tumors and role in tumorigenesis, has an undefined function in non-small cell lung cancer (NSCLC).
