Comparison of three lymph node staging systems in evaluating the prognosis of patients with pT3 esophageal squamous cell carcinoma.

To explore the prognostic value of three lymph node staging systems, including number of positive lymph nodes (pN), lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS), in patients with pT3 stage esophageal squamous cell carcinoma (ESCC). Data from 1667 patients with pT3 stage ESCC who underwent surgical resection were reviewed. The log-rank test was used to assess the differences in overall survival (OS) between groups.

[Gene Diagnosis and Analysis of Clinical Hematological Phenotype of Thailand Deleted α-Thalassemia 1].

Objective: To investigate the hematologic characteristics and gene diagnosis of patients with Thailand deleted α-thalassemia 1, so as to provide the information for clinical genetic counseling.

Methods: The clinical data of 32 patients with Thailand delated α-thalassemia 1 were analyzed retrospectively; the hematologic characteristics and gene diagnosis of Thailand deleted type were investigated by using routine hematologic examination, genetic detection of common thalassemia and Thailand deleted α-thalassemia 1.

Results: Among 32 cases, the Thailand deleted α-thalassemia 1 heterozygote was found in 29 cases, the Thailand deleted α-thalassemia 1 and α(3.
