- Background: The aim was to compare health-related quality-of-life (HRQOL) and cost-effectiveness between cytoreductive surgery with intraperitoneal chemotherapy (CRS + IPC) and systemic chemotherapy for patients with colorectal peritoneal metastases. Methods: Patients included in the Swedish Peritoneal Trial comparing CRS + IPC and systemic chemotherapy completed the EORTC QLQ-C30 and SF-36 questionnaires at baseline, 2, 4, 6, 12, 18, and 24 months. HRQOL at 24 months was the primary endpoint. EORTC sum score, SF-36 physical and mental component scores at 24 months were calculated and compared for each arm and then referenced against general population values. Two quality-adjusted life-year (QALY) indices were applied (EORTC-8D and SF-6D) and an incremental cost-effectiveness ratio (ICER) per QALY gained was calculated. A projected life-time ICER per QALY gained was calculated using predicted survival according to Swedish population statistics. Results: No statistical differences in HRQOL between the arms were noted at 24 months. Descriptively, survivors in the surgery arm had higher summary scores than the general population at 24 months, whereas survivors in the chemotherapy arm had lower scores. The projected life-time QALY benefit was 3.8 QALYs in favor of the surgery arm (p=0.06) with an ICER per QALY gained at 310,000 SEK (EORTC-8D) or 362,000 SEK (SF-6D) corresponding to 26,700-31,200 GBP. Conclusion: The HRQOL in patients with colorectal peritoneal metastases undergoing CRS + IPC appear similar to those receiving systemic chemotherapy. Two-year survivors in the CRS + IPC arm have comparable HRQOL to a general population reference. The treatment is cost-effective according to NICE guidelines.

Journal article (peer-reviewed)abstract
- BACKGROUND: The aim of this study was to investigate epidemiologic and prognostic factors relevant to the treatment of loco-regionally advanced gastric cancer (GC).METHODS: Two hundred and fifty-five patients with GC were identified in Uppsala County between 2000 and 2009. Patient records were analyzed for loco-regionally advanced GC defined as tumor with peritoneal involvement, excluding serosal invasion from the primary tumor only, at primary diagnosis or during follow-up. The presence or not of distant metastasis (DM), including hematogenous metastases (e.g., liver, lung, and bone) and/or distant lymph node metastases, was also analyzed. The Cox proportional hazard model was used for multivariate analysis of factors influencing survival.RESULTS: One hundred and twenty patients (47% of all patients with GC; median age 70.5 years) had loco-regionally advanced disease, corresponding to an incidence of 3.8 per 100,000 person-years. Forty-one percent of these also had DM. Median overall survival (mOS) from the time of the diagnosis of loco-regionally advanced disease was 4.8 months for the total patient cohort, 5.1 months for the subgroup of patients without DM, and 4.7 months for the subgroup with DM. There was no significant difference in mOS between the subgroups with synchronous versus metachronous loco-regionally advanced GC: 4.8 months (range 0.0-67.4) versus 4.7 months (range 0.0-28.3). Using multivariate Cox analysis, positive prognostic factors for survival were good performance status at diagnosis and treatment with palliative chemotherapy and/or radiotherapy. Synchronous DM was a negative prognostic factor. The mOS did not differ when comparing the time period 2000-2004 (5.1 months, range 0-67.4) with the period 2005-2009 (4.0 months, range 0.0-28.3).CONCLUSION: Peritoneal involvement occurred in almost half of the patients with GC in this study and was associated with short life expectancy. New treatment strategies are warranted.

Prophylactic Resorbable Synthetic Mesh to Prevent Wound Dehiscence and Incisional Hernia in High High-risk Laparotomy : A Pilot Study of Using TIGR Matrix Mesh
- 2016

In: Frontiers in Surgery. - : Frontiers Media SA. - 2296-875X. ; 3

Journal article (peer-reviewed)abstract
- Background: Wound dehiscence and incisional hernia are potentially serious complications following abdominal surgery, especially if performed through a midline incision. Although prophylactic reinforcement with on-lay mesh has been shown to reduce this risk, a permanent mesh carries the risk of seroma formation, infection, and persistent pain. The aim of this study was to assess the safety of a reabsorbable on-lay mesh to reinforce the midline suture in patients with high risk for wound dehiscence or incisional hernia.Method: Sixteen patients with three or more risk factors for wound dehiscence or incisional hernia were included. A TIGR® Matrix mesh, composed of a mixture of 40% copolymer fibers of polyglycolide, polylactide, and polytrimethylene carbonate and 60% copolymer fibers of polylactide and polytrimethylene carbonate, was placed on the aponeurosis with an overlap of five on either side and fixated with continuous monofilament polydioxanone suture. All postoperative complications were registered at clinical follow-up.Results: Mean follow-up was 9 months. One patient developed a seroma that needed drainage and antibiotic treatment. One patient had a wound infection that needed antibiotic treatment. There was no complication requiring a reoperation. No wound dehiscence or incisional hernia was seen.Conclusion: On-lay placement of TIGR® Matrix is safe and may provide a feasible way of reinforcing the suture line in patients with high risk for postoperative wound dehiscence or incisional hernia. Larger samples are required, however, if one is to draw any conclusion regarding the safety and effectiveness of this technique.
