Achieving Intraperitoneal Disease Control Using Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Two Cases of Metastatic Breast Cancer
Peritoneal metastases from breast cancer (PMBC) tend to occur late in the disease course and are challenging to manage. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) provide peritoneal disease control in other malignancies and may achieve similar results in PMBC. We...

Sumario: | Peritoneal metastases from breast cancer (PMBC) tend to occur late in the disease course and are challenging to manage. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) provide peritoneal disease control in other malignancies and may achieve similar results in PMBC. We assessed intraperitoneal disease control and outcomes in two PMBC patients after CRS/HIPEC. Patient 1, diagnosed at age 64, had hormone-positive/human epidermal growth factor receptor 2 (HER2)-negative lobular carcinoma treated with mastectomy. Prior to salvage CRS/HIPEC at age 72, five cycles of intraperitoneal chemotherapy via an indwelling catheter failed to control recurrent peritoneal disease. Patient 2, diagnosed at age 52, had hormone-positive/HER2-negative ductal-lobular carcinoma and received lumpectomy, hormonal therapy, and target therapy. Prior to salvage CRS/HIPEC at age 59, she had recurring ascites that was resistant to hormonal therapy and required multiple paracenteses. Both underwent complete CRS/HIPEC with melphalan. The only major complication was anemia, which required a transfusion in both patients. They were discharged on postoperative days 8 and 13, respectively. Patient 1 had peritoneal recurrence 26 months post-CRS/HIPEC and died of disease at 49 months. Patient 2 never had peritoneal recurrence and died of extraperitoneal progression at 38 months. In conclusion, CRS/HIPEC is safe and can provide intraperitoneal disease and symptom control in select patients with PMBC. Thus, CRS/HIPEC can be offered to these rare patients who have failed standard treatments. |
