Linitis plastica, also known as Brinton's disease or leather bottle stomach, is a rare and aggressive form of gastric cancer characterized by the infiltration of cancer cells into the stomach wall, resulting in a rigid, thickened, and non-distensible stomach. This condition is often associated with a poor prognosis due to its tendency to spread to other parts of the body, including the lymph nodes, liver, and peritoneum. The term "linitis plastica" is derived from the Latin words "linitis," meaning inflammation of the lining, and "plastica," meaning formation of a rigid or hardened structure.
The incidence of linitis plastica is relatively low, accounting for approximately 8-14% of all gastric cancer cases. However, its diagnosis and treatment pose significant challenges due to its non-specific symptoms, which can resemble those of other gastrointestinal disorders, such as gastritis or peptic ulcer disease. Patients with linitis plastica often experience weight loss, abdominal pain, nausea, vomiting, and difficulty swallowing, which can lead to delayed diagnosis and treatment. The median survival time for patients with linitis plastica is approximately 7-10 months, highlighting the need for early detection and aggressive treatment.

Pathophysiology and Risk Factors
The exact pathophysiology of linitis plastica is not fully understood, but it is believed to involve the abnormal activation of various cellular signaling pathways, including the PI3K/AKT and MAPK/ERK pathways. These pathways play a crucial role in regulating cell growth, differentiation, and survival, and their dysregulation can lead to the development of cancer. Several risk factors have been identified, including a family history of gastric cancer, infection with Helicobacter pylori, and a diet high in salt and low in fruits and vegetables.
Studies have also shown that certain genetic mutations, such as those affecting the CDH1 and TP53 genes, can increase the risk of developing linitis plastica. The CDH1 gene encodes for the E-cadherin protein, which plays a crucial role in maintaining cell adhesion and preventing cancer cell invasion. Mutations in this gene have been found in approximately 30-50% of patients with linitis plastica. The TP53 gene, on the other hand, encodes for the p53 protein, which functions as a tumor suppressor by regulating cell growth and apoptosis. Mutations in this gene have been found in approximately 20-30% of patients with linitis plastica.
Diagnosis and Staging
Diagnosing linitis plastica can be challenging due to its non-specific symptoms and the lack of specific biomarkers. Endoscopy and biopsy are often used to confirm the diagnosis, and imaging studies such as computed tomography (CT) and positron emission tomography (PET) can help stage the disease. The staging of linitis plastica is based on the TNM system, which takes into account the size and location of the tumor, the presence of lymph node metastases, and the presence of distant metastases.
The prognosis of linitis plastica is generally poor, with a 5-year survival rate of approximately 5-10%. However, early detection and aggressive treatment can improve patient outcomes. Treatment options for linitis plastica include surgery, chemotherapy, and radiation therapy, either alone or in combination. Surgery is often used to remove the tumor and surrounding tissue, while chemotherapy and radiation therapy can help reduce the size of the tumor and alleviate symptoms.
| Stage | Description | 5-Year Survival Rate |
|---|---|---|
| I | Tumor confined to the stomach wall | 20-30% |
| II | Tumor invades the serosa or nearby tissues | 10-20% |
| III | Tumor metastasizes to nearby lymph nodes | 5-10% |
| IV | Tumor metastasizes to distant sites | <5% |
Treatment Options
Treatment options for linitis plastica depend on the stage and location of the tumor, as well as the patient’s overall health. Surgery is often used to remove the tumor and surrounding tissue, while chemotherapy and radiation therapy can help reduce the size of the tumor and alleviate symptoms. Chemotherapy regimens, such as fluorouracil and cisplatin, can be effective in treating linitis plastica, while radiation therapy can help reduce the size of the tumor and alleviate symptoms such as pain and nausea.
In recent years, targeted therapies, such as trastuzumab and ramucirumab, have shown promise in treating linitis plastica. These therapies target specific molecular pathways involved in the growth and spread of cancer cells, and can help improve patient outcomes. Immunotherapy, which harnesses the power of the immune system to fight cancer, is also being explored as a potential treatment option for linitis plastica.
Current Research and Future Directions
Current research is focused on improving our understanding of the molecular mechanisms underlying linitis plastica, as well as developing more effective treatment options. Studies are underway to investigate the role of various molecular pathways, including the PI3K/AKT and MAPK/ERK pathways, in the development and progression of linitis plastica. Additionally, researchers are exploring the potential of targeted therapies and immunotherapy in treating linitis plastica.
Future directions for research include the development of more effective diagnostic tools, such as biomarkers and imaging studies, to improve early detection and diagnosis of linitis plastica. Additionally, the development of more effective treatment options, such as combination therapies and personalized medicine approaches, is crucial to improving patient outcomes.
