Acute myeloid leukemia (AML) with rearrangement (AML-) has been uncommonly reported in adults, and its incidence in our institution is ∼2.5%. There were four men and five women with a median age of 49 years, among which six cases were AML and three were therapy-related.

Methods: A study was conducted on 30 radioiodine refractory papillary thyroid carcinoma patients and 30 radioiodine-avid papillary thyroid carcinoma patients. The expressions of sodium/iodide symporter and mutated protein were determined by immunohistochemistry using formalin-fixed, paraffin-embedded tissue.

Introduction: Second primary tumor (SPT) is a major factor that affects the survival of head and neck squamous cell carcinoma (HNSCC) patients, and the esophagus is a common site. Detection of SPT is essential for optimal HNSCC treatment planning and follow-up. Mutation of the gene is common in head and neck cancer.

While highly effective, this process is expensive in terms of time and clinical resources. We seek to develop and evaluate a computer vision system designed to reasonably infer metastatic origin of secondary liver cancer directly from digitized histopathological whole slide images of liver biopsy.

Acute myeloid leukemia (AML) is a genetically heterogeneous disease that, even with current advancements in therapy, continues to have a poor prognosis. Recurrent somatic mutations have been identified in a core set of pathogenic genes including FLT3 (25-30% prevalence), NPM1 (25-30%), DNMT3A (25-30%), IDH1/2 (5-15%), and TET2 (5-15%), with direct diagnostic, prognostic, and targeted therapeutic implications. Advances in the understanding of the complex mechanisms of AML leukemogenesis have led to the development and recent US Food and Drug Administration (FDA) approval of several targeted therapies: midostaurin and gilteritinib targeting activated FLT3, and ivosidenib and enasidenib targeting mutated IDH1/2.

Although data on these genes are frequently reported in several counties, data specific to these genes among Thai population are scarce. The aim of this study was to investigate and identify molecular alterations associated with colon cancer in Thai population, and to determine the impact of these genetic aberrations on clinical outcome.

Patients with head and neck squamous cell carcinoma are at increased risk of developing a second primary malignancy, which is associated with poor prognosis and early death. To help improve clinical outcome, we aimed to identify biomarkers for second primary malignancy risk prediction using the routinely obtained formalin-fixed paraffin-embedded tissues of the index head and neck cancer. Liquid chromatography-tandem mass spectrometry was initially performed for candidate biomarker discovery in 16 pairs of primary cancer tissues and their matched normal mucosal epithelia from head and neck squamous cell carcinoma patients with or without second primary malignancy.

Objective: To investigate and report the clinical course and outcomes of GS patients after treatment with IVIg at Thailand's largest national tertiary referral hospital METHODS: This retrospective chart review included patients diagnosed with GS and treated with IVIg during the 1 January 2005 to 31 December 2015 study period.
Under physiologic stress, glucocorticoids contribute to thymic involution. While steroids enhance fatty infiltration, this change has not been well studied in the pediatric thymus during illness. Evaluation of 130 thymuses from fetuses, infants and children determined the frequency of thymic fatty infiltration to be low (25%), particularly in fetal thymus (4%).
