HIPEC + EPIC versus HIPEC-alone: differences in major complications following cytoreduction surgery for peritoneal malignancy.

INTRODUCTION: Peritoneal metastases (PM) can be treated with cytoreduction surgery (CRS) with intraoperative heated intraperitoneal chemotherapy (HIPEC) plus or minus early postoperative intraperitoneal chemotherapy (EPIC). HIPEC + EPIC may be associated with more complications than HIPEC alone. METHODS: A prospective database of consecutive patients undergoing CRS + HIPEC ± EPIC at the University of Calgary between February 2000 and May 2011 was reviewed. Patient, tumor, and perioperative variables included peritoneal cancer index (PCI), completeness of cytoreduction (CCR) score, HIPEC ± EPIC type, and grade III/IV complications. RESULTS: 198 patients had a CCR score of 0/1 and received: (1) HIPEC mitomycin C + EPIC 5-fluorouracil for 5 days (n = 85; February 2000-January 2008); or (2) HIPEC oxaliplatin with IV 5-fluorouracil + no EPIC (n = 113; February 2008-May 2011). Clinicodemographics were similar except PCI was higher in the HIPEC-alone group (mean PCI 22 vs. 17; P = 0.02). The rate of grade III/IV complications was higher in the HIPEC + EPIC group (44.7% vs. 31.0%; P = 0.05). On multivariate logistic regression only HIPEC + EPIC and PCI > 26 were associated with an increased rate of complications. CONCLUSION: In patients with PM, the use of EPIC, in combination with CRS and HIPEC, is associated with an increased rate of complications. Surgeons should consider using HIPEC only (without EPIC).

Synoptic surgical reporting for breast cancer surgery: an innovation in knowledge translation.

BACKGROUND: Extensive literature identifies that the quality of surgery not only influences morbidity and mortality but also long-term survival and function. This mandates that we develop a system to capture this information on a real-time basis. METHODS: A synoptic surgical template for breast cancer was created; this was digitized and made available to all surgeons in Alberta. RESULTS: The data reference 1,392 breast cancer procedures. Ninety-one percent of reports were submitted within 1 hour and 97% of reports were submitted within 24 hours. Fifty-two percent of reports were completed within 5 minutes. Information quality with respect to completeness of staging information was present in 89%. Eighty-four percent complied with practice guidelines and 89% of breast surgeons adopted the template. Seventy-five percent of users were moderately or highly satisfied with the system. CONCLUSIONS: The experience with the development and implementation of synoptic surgical reporting has proven to be a successful tool for generating quality surgical data.

Desmoids: a revelation in biology and treatment.

INTRODUCTION: Using a preoperative neoadjuvant chemoradiation protocol, followed by complete excision, we have achieved local control rates exceeding that found in most large series. METHODS: From October 1990 through May 2008, resectable desmoids were initially treated with a preoperative protocol using Adriamycin 30 mg x 3 days continuous intravenous infusion followed by 3,000 cGy of radiation (300 cGy fractions over 10 days). Resection was performed 4-6 weeks later. After 2001, all patients were initially offered Tamoxifen 120 mg/day and Celebrex 400 mg/day for 1 year. Patients who progressed on Tamox/Celeb were treated with protocol and those with stabilization or regression were observed. Patient demographics, tumor size, history of previous recurrences, and follow-up status were recorded prospectively. RESULTS: There were 40 females and 12 males with a mean follow-up of 45 months. Forty patients presented with primary tumors and eight presented with recurrent disease. Thirty-nine patients had surgical resection and 13 were observed. Thirty patients underwent the neoadjuvant protocol. Tamoxifen and Celebrex were used in 16 patients, 6 had stabilization in growth, 1 had a 50% reduction in the size of the tumor, there was 1 complete regression, and 8 progressed. Of the patients who had resectable disease Tamoxifen and Celebrex obviated surgery in 30%. Overall 13% (5) of patients developed a recurrence. There were three recurrences among the protocol group for a local control rate of 90%. CONCLUSION: Although our neoadjuvant protocol demonstrates the best results to date in eradication of disease, an initial conservative approach is reasonable to determine who would most benefit from surgery.

Prophylactic laparoscopic-assisted total gastrectomy for hereditary diffuse gastric cancer.

BACKGROUND: Ten percent of gastric cancer (GC) cases are familial, with one third resulting from a mutation in the tumor suppressor gene CDH1. Loss of this important structure can result in hereditary diffuse gastric cancer (HDGC), which carries a high mortality if early diagnosis is not made. Despite its clear genetic origin, optimal management of HDGC family members is controversial, as the utility and efficacy of current cancer screening programs for mutation carriers are unproven. METHODS: A 53-year-old Caucasian woman was initially seen for genetic screening because multiple family members had mutations of the CDH1 gene. Her pedigree analysis demonstrated 4 generations of gastric cancer, and 2 of the generations carried the CDH1 germline mutation, consistent with HDGC. At endoscopy, the patient's gastric mucosa was normal and random biopsies were also normal. The patient underwent a laparoscopic total gastrectomy. RESULTS: The gross examination of her stomach appeared normal. On histologic examination, however, the stomach was found to have diffuse (signet ring cell) adenocarcinoma in-situ with 11 microscopic foci of invasive adenocarcinoma limited to the lamina propria. CONCLUSION: Our case is the first reported prophylactic total gastrectomy utilizing a laparoscopic approach, and it highlights the importance of taking a thorough family history and obtaining a pedigree analysis. Endoscopic screening in HDGC cannot rule out diffuse GC, because the stomach and biopsies can be normal despite the presence of adenocarcinoma. Therefore, our case supports the recommendation for prophylactic gastrectomy in HDGC.

Solid-pseudopapillary tumors of the pancreas: case report and literature review.

Solid pseudopapillary tumors (SPT) of the pancreas are rare neoplasms of low malignant potential that mostly affect young women. These tumors are of unclear pathogenesis, are slow growing, and can become considerably large before causing symptoms. Complete resection is curative in most cases. This is the case of a 39-year-old African-American woman undergoing evaluation for Roux-en-Y gastric bypass, who was found to have a pancreatic mass. Image-guided biopsy revealed SPT. The patient underwent complete excision of the tumor and had an open Roux-en-Y gastric bypass performed concurrently. The patient had an uneventful postoperative course. A review of the literature is presented.
