[Extranodal NK/T-cell lymphoma, nasal type: a clinical analysis]
1Department of Otorhinolaryngology-Head and Neck Surgery, Zhujiang Hospital, Southern Medical University, Guangzhou, 510282, China.
Summary
Extranodal NK/T-cell lymphoma, nasal type (ENKTL) has a poor prognosis, but early stages treated with radiotherapy alone show better outcomes. Advanced stages benefit from combined chemotherapy and radiotherapy.
Area of Science:
- Oncology
- Hematology
- Pathology
Background:
- Extranodal NK/T-cell lymphoma, nasal type (ENKTL) is an aggressive malignancy with challenging treatment paradigms.
- Understanding clinical factors influencing ENKTL prognosis is crucial for personalized therapeutic strategies.
Purpose of the Study:
- To investigate the clinical characteristics, diagnostic approaches, and treatment outcomes of ENKTL.
- To identify key prognostic factors for optimizing individualized patient management.
Main Methods:
- Retrospective analysis of 25 ENKTL patient cases from December 2009 to July 2016.
- Evaluation of clinical manifestations, EBV-DNA levels, imaging, Ann Arbor staging, histological grade, treatment modalities, and survival data.
- Statistical analysis including Kaplan-Meier, Log-rank tests, and Cox proportional hazard models.
Main Results:
- Early stage ENKTL (ⅠE-ⅡE) showed 100% 1- and 3-year overall survival (OS), while advanced stages (ⅢE-ⅣE) had significantly lower OS (40.0% and 26.7%).
- Radiotherapy alone yielded superior outcomes in early stages (100% 1- and 3-year OS), whereas chemotherapy alone had the poorest prognosis.
- Multivariate analysis identified disease course, B symptoms, positive EBV-DNA copy number, and treatment modality as independent prognostic factors.
Conclusions:
- ENKTL is characterized by aggressive invasion and generally poor prognosis.
- Early-stage, localized ENKTL may be effectively treated with radiotherapy alone.
- Combined chemotherapy and radiotherapy is recommended for advanced or aggressive ENKTL cases.

01:25Immune Surveillance by NK Cells and Phagocytes
8.8K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

01:24Nose and Nasal Cavity
12.1K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

01:29Administering Oxygen by Nasal Cannula
3.3K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

01:24T Cell Types and Functions
2.5K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:01Classification of Titrimetric Analysis Based on Reaction Types
1.8K
Titrimetric analysis in solution chemistry involves measuring the volume of solutions and is often called volumetric analysis. The standard solution of known concentration in the burette is called the titrant, whereas the solution of unknown concentration in the flask is called the analyte, or titrand. Titrimetric analyses can be classified into four types based on the reactions between the titrant and analyte.
