Abstract Background Complete cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is the only curative treatment for pseudomyxoma peritonei (PMP) arising from the appendix. High peritoneal carcinomatosis index (PCI) is associated with an increased risk of surgical complications. The objective of this study was to present the results of a planned two-step surgical strategy to decrease postoperative morbidity and improve resectability of patients with very high PCI. Methods All consecutive patients who underwent a planned two-step surgical approach for PMP between January 2012 and March 2020 were retrospectively included. This approach was offered for patients with low-grade PMP with PCI > 28 for which feasibility of a complete CRS in one operation was uncertain. The first surgery included a complete CRS of the inframesocolic compartment and omentectomy. HIPEC was delivered at the second surgery, after complete CRS of the supramesocolic compartment. Postoperative morbidity was assessed using the Clavien-Dindo classification and survival results were also collected. Results Eight patients underwent the two-step approach. The median PCI was 33 (29–39) and the median time between the two procedures was 111 days (90–212 days). One patient was deemed unresectable at the second surgery. The rate of major morbidity was 0% for the first step and 25% for the second step, with no mortality. Median follow-up was 53.8 months (3–73 months). Conclusion A two-step surgical management for low-grade PMP patients with very high PCI is safe and feasible, with acceptable postoperative morbidity and no compromise on oncological outcomes.

Postoperative morbidity was assessed using the Clavien-Dindo classification and survival results were also collected. Results Eight patients underwent the two-step approach.

Appendiceal Adenocarcinoma

e16276 Background: Appendiceal adenocarcinoma is relatively rare and often diagnosed incidentally during operations for acute appendicitis. It is commonly associated, either at time of initial presentation or upon recurrence, with peritoneal metastases. A typical treatment strategy for patients with peritoneal disease includes cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Extrapolating largely from literature in colorectal cancer, chemotherapy is frequently given before and/or after CRS/HIPEC though high-level evidence to support this is lacking. We sought to evaluate the effect of systemic chemotherapy on survival. Methods: Utilizing a database of CRS/HIPEC procedures at University of Colorado Hospital from 2008 to present we retrospectively reviewed cases of appendiceal adenocarcinoma. Data collected included staging, histologic grade, chemotherapy given, surgical outcomes, and time to disease recurrence. Patients without adequate information regarding treatment, or without at least 1 year of clinical follow-up, were excluded. Associations between administration of chemotherapy or histologic grade and 1-year DFS were analyzed using Fisher’s exact test, and logistic regression was used to assess whether 1-year DFS were different in chemotherapy-treated patients when adjusted for histologic grade. Results: In total, 117 cases reviewed indicated an appendiceal pathology. Of these, 54 cases in a total of 51 patients met the specified criteria for pathology and completeness and length of follow-up information. The average age was 58 years (range 26-81 years). Adenocarcinoma was graded as low in 15 (28%) cases, intermediate in 18 (33%) cases, and high in 21 (39%) cases. 23 (43%) patients received no chemotherapy while 31 (57%) received chemotherapy before and/or after surgery. In the overall population, there was no significant effect of chemotherapy on survival, with 1-year DFS demonstrated in 74.2% of patients receiving some chemotherapy and 70% in patients not receiving chemotherapy (p = 0.765). One-year DFS was achieved in 86% of low-grade cases, 61% of intermediate-grade cases, and 71% of high-grade cases, though this was also not statistically significant (p = 0.254). Furthermore, when 1-year DFS between chemotherapy and non-chemotherapy patients was adjusted for grade, there was again no significant interaction (odds ratio = 0.48, 95% C.I. (0.13-1.64), p = 0.763). Conclusions: In this small, single-institution experience of patients with peritoneal appendiceal adenocarcinoma, there was no significant effect of chemotherapy administration on 1-year DFS. These findings are likely affected by significant confounding with the small sample size and retrospective nature of the data. Further investigation on a larger scale is warranted.
