Can gynecological tumors cause pleural effusion?

Gynecologic tumors may cause pleural effusions, especially in advanced malignancies, due to metastasis or associated lymphatic obstruction. Causes may include pleural inflammation caused by tumor metastasis and compression of lymphatic and blood vessels by the tumor. Fluid imbalance and cachexia are also potential factors. Early detection and aggressive treatment can reduce the incidence of complications.

1. Tumor metastasis: Gynecological tumors, such as ovarian cancer and endometrial cancer, often metastasize to the abdomen and chest cavity in the late stage, causing pleural effusion. Tumor cells may directly invade the pleura, causing inflammation and effusion. CT or MRI examinations can help identify the nature of the effusion and make a definitive diagnosis through thoracentesis.

2. Lymphatic obstruction: Gynecological tumors often compress or invade lymphatic vessels, resulting in obstruction of lymphatic reflux and increasing the fluid burden in the chest and other parts. In order to relieve this symptom, chest drainage is usually required while controlling the primary tumor.

3. Fluid metabolism disorder: Patients with malignant tumors may suffer from fluid metabolism disorder due to malnutrition, protein deficiency and other factors, which may lead to pleural effusion. Protein supplementation and dietary conditioning can partially improve this condition.

4. Cachexia: A common systemic exhaustion state in advanced malignant tumors, which not only worsens the nutritional status of patients, but may also lead to serious complications such as pleural effusion. At this time, comprehensive chemotherapy, targeted therapy and supportive therapy are needed for all-round management.

For pleural effusion caused by gynecological tumors, early identification and treatment are key. Combined with imaging and laboratory tests, the diagnosis is confirmed and the appropriate treatment plan is selected. Treatment strategies include tumor resection or reduction, chemotherapy, targeted drug therapy, and symptomatic treatment such as chest drainage. Paying attention to the patient's nutrition and psychological state is also an important goal. Through these comprehensive measures, the symptoms of pleural effusion can be effectively alleviated and the patient's quality of life can be improved.
