Abstract
Background: Combined administration of intravenous (iv) and intraperitoneal (ip) (iv/ip) chemotherapy is an effective adjuvant treatment option after primary debulking surgery (PDS) for advanced ovarian cancer (OC). Increased toxicityand patient burden limit its use in daily practice.
Objective: To assess toxicity and survival outcomes of iv/ip chemotherapy in daily practice in the Netherlands.
Methods: This retrospective cohort study included 81 women who underwent at least an optimal PDS for FIGO stage III OC followed by iv/ip chemotherapy according to the Armstrong regimen, in four hospitals in the Netherlands between January 2007 and May 2016. We collected information on surgical procedure, abdominal port implantation, toxicity, and recurrence-free and overall survival.
Results: All participants underwent PDS, of whom 60 (74%) had their ip catheter implanted during PDS. Most frequently reported all grade toxicity was haematological n = 44 (54%). Forty-four patients (54%) completed all six cycles of iv/ip chemotherapy. The most frequent causes of discontinuation of iv/ip administration were renal dysfunction (12/37 = 32%) and catheter problems (7/37 = 19%). Median recurrence-free survival and overall survival were 24 months (range 0 – 108) and 80 months (range 4-115), respectively. Surgical outcome, completion of more than three courses of treatment and intra-abdominal localisation of recurrent disease were associated with better survival outcomes.
Conclusion: In daily practice, 54% of patients with advanced OC could complete all scheduled cycles of iv/ ip chemotherapy with acceptable morbidity and toxicity, leading to outcomes comparable with the results of published trials on iv/ip chemotherapy.
