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 diffusely infiltrating the stomach wall, submucosal fibrosis and thickening, with 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, thick, rigid, leather bottle-like stomach from diffuse infiltration of the stomach wall by the tumor cells are characteristic findings of linitis plastica.[5] On microscopic histopathological analysis, atypical signet ring cells diffusely infiltrating the stomach wall, submucosal fibrosis and thickening, with 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.[6]
Causes
Linitis plastica may be caused by lye ingestion or metastatic infiltration of the stomach, mostly breast and lung carcinoma.[7]
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.[8][9]
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.[8]Hereditary form of diffuse gastric adenocarcinoma (HDGC) is usually first diagnosed before 40 years of age, sometimes even before the age of 25 years.[8]Females are slightly more affected with linitis plastica than males.[8]Linitis plastica usually affects individuals of the Asian race, particularly the Japanese.[10]
Risk factors
Common risk factors in the development of linitis plastica may include Asian race, female gender and the presence of CDH1 gene mutations.[11][12]
Screening
Patients who have a relative with hereditary diffuse gastric adenocarcinoma (HDGC) should be screened earlier for CDH1 gene mutations.[3]
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.[13][14] 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.[14]
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.[15][16] [13] 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. [17][18]
Laboratory findings
Laboratory findings consistent with the diagnosis of linitis plastica may include abnormal complete blood picture, electrolyte abnormalities, occult blood in stool, abnormal increase in the levels of ALT (alanine aminotransferase), lactate dehydrogenase (LDH), aspartate transaminase (AST) and positive tumor markers like the CA-125, CEA and beta hCG.[19]
Upper GI Endoscopy
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.[20]
Other imaging findings
Chest x-ray, CT and MRI of chest, abdomen and pelvis may be performed to detect the local invasion and metastasis of linitis plastica to breast, lungs and liver.[19]
Treatment
Medical therapy
The predominant therapy for linitis plastica is surgical resection. Adjunctive chemotherapy and radiation may be required.[8]
Surgery
Total gastrectomy is recommended for the management of local disease. Surgical resection is not recommended among patients with metastatic linitis plastica. [21]
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.[22]
Secondary prevention
There are no secondary preventive measures available for linitis plastica.
