Summary
Primary gastrointestinal non-Hodgkin lymphoma (gNHL) is rare, affecting the stomach, small intestine, and ileocecal region. While diagnosis and management have advanced, T-cell lymphomas remain a therapeutic challenge.
Area of Science:
- Gastroenterology
- Hematology
- Oncology
Background:
- The gastrointestinal (GI) tract is the most common extranodal site for non-Hodgkin lymphoma (NHL).
- Primary gastrointestinal NHL (gNHL) accounts for 10-15% of all NHL cases and 30-40% of extranodal NHL.
- GI lymphomas can originate from mature B, T, or NK/T cells, with diffuse large B-cell lymphoma and marginal zone lymphoma (MALT) being most frequent.
Purpose of the Study:
- To review the clinical and pathological features of GI lymphomas.
- To describe current diagnostic and treatment strategies for gNHL.
- To highlight challenges in managing specific GI lymphoma subtypes, particularly T-cell lymphomas.
Main Methods:
- Literature review of clinical and pathological features of GI lymphomas.
- Analysis of current diagnostic modalities for gNHL.
- Evaluation of established and emerging treatment approaches for GI lymphomas.
Main Results:
- gNHL most commonly occurs in the stomach, followed by the small intestine and ileocecal region.
- Significant advancements in diagnosis, staging, and management of GI lymphomas have been made in the last two decades.
- T-cell lymphomas within the GI tract continue to present therapeutic difficulties.
Conclusions:
- gNHL encompasses diverse lymphoid neoplasms with varying clinical presentations and risk factors.
- Despite progress, optimal management strategies for all gNHL subtypes, especially T-cell lymphomas, require further development.
- A comprehensive understanding of GI lymphoma characteristics is crucial for effective patient care.

01:20Histology of the Gastrointestinal (GI) Tract
3.3K
The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

1.1K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

01:22Physiology of the Gastrointestinal System II: Digestion and Absorption
1.8K
The gastrointestinal (GI) tract, extending from the mouth to the anus, plays a pivotal role in the digestion and absorption of nutrients. This process involves both mechanical and chemical actions facilitated by various enzymes.
Digestion begins in the mouth, where food undergoes mechanical breakdown by chewing and combines with saliva. Salivary amylase, an enzyme in saliva, starts the breakdown of starches into maltose. The food then travels down the esophagus to the stomach.

1.4K
The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...
