We present our experience of 10 cases of pseudomyxoma peritonei treated in our regional hospital between 1978 and 1992. We note the rarity of this disease; the catastrophic macroscopic appearance may mislead the in experienced surgeon. Preoperative diagnosis is usually easy when confronted with a mass in an ascitic abdomen, with the help of ultrasonography and CT-scan, and above all after abdominal puncture which produces pathognomonic gelatinous fluid. Most cases are derived from the ovary and appendix. Treatment is surgical and aggressive; we adopt the protocol proposed by Sugarbaker which combines repeated surgery and local and systemic chemotherapy. The relatively good survival, even in the malignant cases, seems to be improved by this treatment.

Long term outcomes associated with the use of perioperative systemic chemotherapy on low grade appendiceal mucinous neoplasms with pseudomyxoma peritonei treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Introduction: Low grade appendiceal mucinous neoplasms (LAMN) are indolent tumors that lack invasive potential but may present as pseudomyxoma peritonei. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) significantly improves both overall and recurrence free survival. While systemic chemotherapy is generally considered ineffective for LAMN, little literature is available to support this notion.

Introduction: Cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) represent a high-risk for venous thromboembolism (VTE) due to malignancy, prolonged surgery and immobility. We investigated the incidence of and risk factors for VTE following CRS/IPC.
Materials And Methods: Data was analysed on 130 CRS/IPC performed over a 6-year period at a single centre, the Western Australian Peritonectomy Service (WAPS), on lower gastrointestinal neoplasia: pseudomyxoma peritoneii (PMP), colorectal cancer (CRC) and appendix cancer (AC).

Background: Prediction of open-close and long-term outcome is challenging in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Prognostic scores often include factors not known at baseline. Therefore, we aimed to analyze whether patterns of preoperative tumor markers could aid in prediction of open-close surgery and outcome in patients with pseudomyxoma peritonei (PMP) or colorectal peritoneal metastases (PM).

Histologic grade is a key predictor for pseudomyxoma peritonei (PMP) of appendiceal origin that is used to guide clinical management. However, some tumors demonstrate disease behavior that deviates from their histologic grade. A recent study suggested that TP53, GNAS, and RAS mutation analysis could stratify tumors into distinct molecular groups with different prognosis.
