Overview

The term "linitis plastica" was first used by Dr. William Brinton, an English physician, in 1854.[1][2] Development of linitis plastica is the result of genetic mutation in the CDH1 (E-cadherin) gene, that is responsible for intercellular adhesions.[3] On gross pathology, a thick, rigid, and leather bottle-like stomach wall is a characteristic finding of linitis plastica.[4] On microscopic histopathological analysis, atypical signet ring cells that diffusely infiltrate the stomach wall, submucosal fibrosis and thickening, and a minimal mucosal involvement are characteristic findings of linitis plastica. Linitis plastica usually affects individuals of the Asian race.[4] The presence of metastasis is associated with a particularly poor prognosis among patients with linitis plastica. Linitis plastica is associated with a 5-year survival rate of approximately 10-20% in Japan.[3] Total gastrectomy is recommended for the management of local disease and as a prophylactic surgery in patients with hereditary form of linitis plastica.[3]

Historical Perspective

The term "Linitis plastica" was first used by Dr. William Brinton, an English physician, in 1854.[1]

Pathophysiology

On gross pathology, a thick, rigid, and leather bottle-like stomach wall is a characteristic finding of linitis plastica.[4] On microscopic histopathological analysis, atypical signet ring cells that diffusely infiltrate the stomach wall, submucosal fibrosis and thickening, and a minimal mucosal involvement are characteristic findings of linitis plastica. Development of linitis plastica is the result of genetic mutation in the CDH1 (E-cadherin) gene, that is responsible for intercellular adhesions.[3]

Causes

The most common cause of linitis plastica is scirrhous adenocarcinoma. Linitis plastica may be caused by germline mutations in the CDH1 (E-cadherin) gene.[5][1]

Differntiating Linitis Plastica from Other Diseases

Linitis plastica must be differentiated from other diseases that cause thickening of the gastric wall such as lymphoma, other forms of gastric adenocarcinoma, menetrier's disease, lymphoid hyperplasia, amyloidosis, and granulomatous diseases.[3][1]

Epidemiology and Demographics

Hereditary form of diffuse gastric adenocarcinoma (HDGC) is usually first diagnosed before 40 years of age, sometimes even before the age of 25 years.[3] Females are slightly more affected with linitis plastica than males.[3]Linitis plastica usually affects individuals of the Asian race, particularly the Japanese.[4]

Risk Factors

Common risk factors in the development of linitis plastica may include Asian race, female gender, and the presence of CDH1 gene mutations.[6][3]

Screening

There is insufficient evidence to recommend routine screening for linitis plastica.

Natural History, Complications and Prognosis

If left untreated, patients with linitis plastica may progress to develop symptoms from decreased peristalsis of the stomach that may include dyspepsia, dysphagia, nausea, vomiting, increased satiety, and regurgitation.[7][3] Depending upon the stage of linitis plastica at the time of diagnosis, the prognosis may vary. The presence of metastasis is associated with a particularly poor prognosis among patients with linitis plastica. Linitis plastica is associated with a 5-year survival rate of approximately 10-20% in Japan.[3]

Diagnosis

History and Symptoms

Symptoms of linitis plastica may include dyspepsia, nausea, vomiting, early satiety, loss of appetite, weight loss, abdominal pain/discomfort, and sometimes diarrhea.[3][4][7] A positive family history of diffuse gastric cancer may be present if it is the hereditary form of the disease.

Physical Examination

Common physical examination findings of linitis plastica may include lymphadenopathy, organomegaly, and signs of ascites.[8][9]

Laboratory Findings

Laboratory findings consistent with the diagnosis of linitis plastica may include abnormal complete blood picture, electrolyte abnormalities, and occult blood in stool.[9]

Electrocardiogram

There are no electrocardiogram findings associated with linitis plastica.

CT

On CT abdomen, linitis plastica is characterized by diffusely thickened stomach with a small lumen. CT of chest, abdomen and/or pelvis may be performed to detect metastases to lymph nodes or any other organs.[1]

MRI

MRI of chest, abdomen and/or pelvis may be performed to detect local invasion and metastasis from or of linitis plastica to breast, lungs and liver.[10]

Other Imaging Findings

Upper GI series may be helpful in the diagnosis of linitis plastica. Findings on upper GI series suggestive of linitis plastica include inadequately distended stomach with increased rigidity and a narrow stomach lumen, loss of normal mucosal fold pattern, and distorted, thickened or nodular mucosa.[1]

Other Diagnostic Studies

On upper GI endoscopy, linitis plastica may show superficial ulcers and/or inflammation. On endoscopic ultrasound, abnormal thickening of the stomach wall is a characteristic finding.[3]

Treatment

Medical Therapy

The predominant therapy for linitis plastica is surgical resection. Adjunctive chemotherapy and radiation may be required.[3]

Surgery

Total gastrectomy is recommended for the management of local disease. Surgical resection is not recommended among patients with metastatic linitis plastica.[3]

Primary Prevention

Effective measure for the primary prevention of hereditary diffuse gastric adenocarcinoma includes prophylactic gastrectomy in individuals who test positive for CDH1 gene mutations.[11]

Secondary Prevention

There are no secondary preventive measures available for linitis plastica.
