A Clinicopathological Analysis of Recurrent Gastric Cancer
Cancer Research and Treatment
|December 19, 2015
Summary
Understanding gastric cancer recurrence is key. Clinicopathologic factors like T stage and N stage predict recurrence patterns. Curative resection offers survival benefits for recurrent gastric cancer patients.
Area of Science:
- Oncology
- Gastroenterology
- Surgical Oncology
Background:
- Gastric cancer recurrence poses significant challenges.
- Identifying prognostic factors for recurrence is crucial for patient management.
Purpose of the Study:
- To investigate the correlation between clinicopathologic characteristics and gastric cancer recurrence patterns.
- To define survival differences based on treatment modalities after recurrence diagnosis.
Main Methods:
- Retrospective review of 4184 gastric cancer patients who underwent radical surgery.
- Analysis of clinicopathologic factors and their relationship with recurrence patterns.
- Comparison of survival rates across different treatment modalities post-recurrence.
Main Results:
- Recurrence confirmed in 1141 patients with various patterns: loco-regional, peritoneal, distant, and mixed.
- T stage, N stage, tumor size, and perineural invasion identified as independent prognostic factors for recurrence.
- Median survival varied significantly by treatment: 24.2 months (curative operation), 7.7 months (chemotherapy), 7.1 months (non-curative operation), and 3.3 months (conservative treatment).
Conclusions:
- Clinicopathological analysis reveals distinct recurrent patterns and prognostic factors in gastric cancer.
- Curative resection demonstrates a survival benefit for patients with recurrent gastric cancer, particularly in cases with limited disease extent.

3.3K
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

01:17Gastritis-II: Pathophysiology
1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
