Peritoneal Mesothelioma

Specialty: Oncology

Category: Sarcomas

Sub-category: Rare Cancers

Symptoms:
abdominal pain; swelling in the abdomen; unexplained weight loss; nausea; vomiting; loss of appetite; fatigue; bloating; constipation

Root Cause:
Peritoneal mesothelioma is a rare cancer that affects the peritoneum, the lining of the abdomen. It is most commonly caused by asbestos exposure, which leads to the development of malignant cells that grow and invade the peritoneal lining.

How it's Diagnosed: videos
Diagnosis typically involves imaging studies such as CT scans, MRIs, or ultrasounds to detect fluid buildup (ascites) and tumors in the abdomen. A biopsy is needed for definitive diagnosis, often performed through laparoscopy or peritoneal biopsy.

Treatment:
Treatment options include surgery (e.g., cytoreductive surgery) to remove as much of the tumor as possible, often followed by heated chemotherapy (HIPEC) to target remaining cancer cells. Chemotherapy (e.g., pemetrexed and cisplatin) is used for advanced cases, and radiation therapy may also be applied.

Medications:
Common chemotherapy drugs used to treat peritoneal mesothelioma include pemetrexed (an antifolate drug) and cisplatin (a platinum-based chemotherapy agent). These are used in combination to help shrink tumors and manage the disease. In some cases, targeted therapies or immunotherapy may be considered.

Prevalence: How common the health condition is within a specific population.
Peritoneal mesothelioma is extremely rare, accounting for approximately 10-20% of all mesothelioma cases. The overall incidence is low, with an estimated 300-500 new cases diagnosed annually in the United States.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
The primary risk factor is exposure to asbestos, particularly in occupations like construction, shipbuilding, and manufacturing. Other risk factors include genetic mutations and a history of prior radiation exposure.

Prognosis: The expected outcome or course of the condition over time.
The prognosis for peritoneal mesothelioma is poor, with a median survival rate of 12-24 months, depending on the stage at diagnosis. Patients who undergo cytoreductive surgery with HIPEC may have improved outcomes, but survival is still limited.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Complications include bowel obstruction, ascites (fluid buildup in the abdomen), malnutrition, and metastasis to other parts of the body, particularly the lungs. The treatment itself can also cause side effects like fatigue, nausea, and immune suppression.

Hypercalcemia of Malignancy

Specialty: Oncology

Category: Sarcomas

Sub-category: Paraneoplastic Syndromes

Symptoms:
nausea; vomiting; constipation; abdominal pain; fatigue; confusion; thirst; frequent urination; muscle weakness

Treatment:
Hydration, bisphosphonates (such as zoledronic acid), denosumab, corticosteroids, and calcitonin.

Medications:
Bisphosphonates (e.g., zoledronic acid) inhibit bone resorption, and denosumab , a monoclonal antibody, works by inhibiting osteoclast activity. Corticosteroids (e.g., dexamethasone ) may be used if there is an underlying hematologic malignancy. Calcitonin helps to lower calcium levels by inhibiting osteoclast function.

Prevalence: How common the health condition is within a specific population.
Affects approximately 10-20% of patients with advanced cancer.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Patients with lung, breast, or hematologic cancers, and those with extensive bone metastasis.

Prognosis: The expected outcome or course of the condition over time.
The prognosis depends on the underlying malignancy and the ability to control calcium levels. Treatment of the underlying cancer can improve the prognosis.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Severe hypercalcemia can cause kidney failure, arrhythmias, coma, and, if untreated, death.
