Primary Peritoneal Carcinoma

Synonyms

PPC,

Overview

Primary peritoneal carcinoma (PPC) is a rare, aggressive tumor originating from the peritoneal lining that closely mimics epithelial ovarian cancer. Key features include presentation mostly in older women, elevated CA-125 levels, and similar treatment protocols.

Symptoms

Primary peritoneal carcinoma symptoms are often vague and mimic gastrointestinal issues, commonly including abdominal bloating or swelling from fluid buildup (ascites), persistent abdominal pain or pressure, and a feeling of fullness quickly after eating.

Causes

The exact exact cause of primary peritoneal carcinoma (PPC) is unknown, but key risk factors include BRCA1 or BRCA2 gene mutations, older age (averaging around 60 years), and a family history of ovarian or breast cancer.

Prevention

Primary peritoneal carcinoma cannot be completely prevented, but risk can be lowered using ⁠National Cancer Institute guidelines such as oral contraceptives, tubal ligation, and risk-reducing surgery.

Diagnosis

Primary peritoneal carcinoma diagnosis involves blood tests, imaging studies, and tissue biopsies. Key methods include measuring the CA-125 tumor marker, performing CT or MRI scans, and analyzing abdominal fluid or tissue samples.

Prognosis

Primary peritoneal carcinoma (PPCa) carries a guarded prognosis, with a median overall survival generally ranging between 12 and 18 months and an overall 5-year survival rate reported around 26% to 40%. Because the disease is frequently diagnosed at an advanced stage, outcomes closely mirror those of advanced epithelial ovarian cancer.

Treatment

Primary peritoneal carcinoma treatment relies on surgery, chemotherapy, and targeted therapy, commonly combining a full operation to remove visible tumors with powerful systemic or heated localized drug treatments.
