Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in peritoneal carcinomatosis from ovarian cancer

BACKGROUND: In selected patients with peritoneal carcinomatosis from ovarian cancer prognosis can be improved by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: Between September 1995 and February 1999, 19 patients (mean age 52 years, range 30–72 years) with peritoneal carcinomatosis from primary or recurrent epithelial ovarian carcinoma were operated with the aim of complete macroscopical cytoreduction. Surgery was followed by intraoperative HIPEC. The data was analyzed retrospectively. RESULTS: Eleven patients had recurrent and 8 primary ovarian cancer. The median progression free interval was 18 months (range 6–36 months). Macroscopically complete cytoreduction was achieved in 9 patients. Cisplatin (n = 16) or mitoxantrone (n = 3) were used for the intraoperative chemotherapy. The median intraabdominal inflow temperature was 41.5°C. Complications occurred in seven patients. Most frequent complications were anastomotic leakage (2/19) and intraabdominal abscess formation (2/19). One patient died postoperatively. The mean (± SD) overall survival time was 33(± 6) months with a 5-year survival rate of 15%. The survival was found to be influenced by the completeness of cytoreduction (44 ± 11 vs. 25 ± 6 months, p = 0.40), tumor volume (54 ± 10 versus 16 ± 4, p = 0.002) and presence of lymph node (38 ± 8 vs. 20 ± 8 months, p= 0.2) or liver metastases (51 ± 9 vs. 21 ± 6 months, p = 0.06). CONCLUSIONS: Cytoreductive surgery combined with HIPEC is feasible and is associated with a reasonable morbidity and mortality. Complete cytoreduction may improve survival in select group of patients with low tumor volume and no organ metastases

Mesenchymal Stromal Cell-Based Therapy (Editorial)

The use of mesenchymal stromal cells (MSCs) for clinical application is intensively investigated for a variety of areas, such as bone repair, haematological and autoimmune diseases, and solid organ transplantation. Moreover, increasing insights into their mechanism of actions revealed a lively (paracrine) interaction between MSCs and recipient (immune) cells and identified novel mediators such as extracellular vesicles (EVs). Both paracrine signals and EVs have been shown to play a role in the effects of MSCs and may potentially complement MSC-based therapies or represent therapeutic alternatives. This Special Issue of Cells is devoted to the many aspects of MSC-based therapy and includes original data papers and reviews on preclinical models, clinical studies, as well as MSC manufacturing protocols.

Surgical Site Infections and their economic significance in hepatopancreatobiliary surgery: A retrospective incidence, cost, and reimbursement analysis in a German centre of the highest level of care

Surgical site infections (SSI) in open Hepatopancreatobiliary (HPB) surgery are common complications. They worsen patients’ outcomes and prolong hospital stays. Their economic significance in the German diagnosis related groups (DRG) system is mostly unknown. To investigate their economic importance, we evaluated all cases for SSIs as well as clinical and financial parameters undergoing surgery in our centre from 2015 and 2016. Subsequently, we carried out a cost-revenue calculation by assessing our billing data and the cost matrix of the InEK (German Institute for the Payment System in Hospitals). A total of 13.5% of the patients developed a superficial, 9% a deep incisional, and 2.4% of the patients an organ space SSI. Compared with Patients without SSI, Patients with SSI had more comorbidities, were older, and their average length of stay was extended by 19 days (P < .001). The financial loss per SSI-case was €-7035.65 despite increased reimbursement, which resulted in a calculated total loss for the hospital of €-802 064.62 in 2015 and 2016. Surgical site infections are common complications of open HPB surgery, which lead to a significant increase in the cost per case. Further prevention strategies need to be developed. Besides, an adjustment of revenues must be demanded
