What Are the Late-Stage Symptoms of Malignant Peritoneal Mesothelioma?

What are the late-stage symptoms of malignant peritoneal mesothelioma? Peritoneal mesothelioma is a relatively rare tumor. In its early stages, it typically produces no obvious symptoms; only when the tumor grows to a certain size and invades intra-abdominal organs—such as the stomach and intestines—do symptoms emerge, posing a threat to health. Therefore, it warrants close attention. So, what are the late-stage symptoms of malignant peritoneal mesothelioma?

What Are the Late-Stage Symptoms of Malignant Peritoneal Mesothelioma?

In the late stage, malignant peritoneal mesothelioma may present with paroxysmal pain or sudden, severe pain. Late-stage symptoms often include abdominal pain, which may manifest as persistent dull pain, distension-related pain, paroxysmal pain, or sudden, intense pain. Pain commonly occurs in the upper abdomen or right upper quadrant; however, when it arises in the lower abdomen, it may lead to clinical misdiagnosis—as ectopic pregnancy or pelvic tumor, for example. Moreover, abdominal pain is associated with invasion of the parietal peritoneum, adhesions between the tumor and gastrointestinal tract or pelvic organs (causing intestinal obstruction or organ torsion), massive ascites, and space-occupying effects of abdominal masses.

Peritoneal mesothelioma is a malignant tumor. If diagnosed early, surgical intervention should be promptly pursued. However, many patients are already in the advanced stage at diagnosis—often complicated by massive ascites. In such cases, intravenous chemotherapy is an option; additionally, paracentesis (abdominal fluid drainage) and intraperitoneal chemotherapy may be performed to alleviate disease progression and reduce suffering caused by advanced-stage tumor burden.

Adopting healthy lifestyle habits is essential. Nutrition should be well-balanced, with emphasis on high-protein foods. Abundant high-quality protein supports immune function and enhances resistance to disease, thereby facilitating patient recovery. We hope this information proves helpful.
