[PMID: 38893218 PMCID: PMC11171061 DOI: 10.3390/cancers16112099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/20/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Careful macroscopic assessment of surgical scars is needed to avoid routine scar resection during cytoreductive surgery (CRS) for peritoneal metastases (PM). This study aimed to analyze the correlation between macroscopically suspected and microscopically confirmed scar metastases (SMs), and to analyze the prognostic impact of not undergoing routine scar resection. METHOD All patients with previous surgery, treated with CRS and hyperthermic intraperitoneal chemotherapy, for colorectal PM or pseudomyxoma peritonei (PMP), at Uppsala University Hospital in 2013-2021, were included. Macroscopic SMs in surgical reports were compared with histopathological analyses. RESULTS In total, 227 patients were included. Among colorectal PM patients (n = 156), SM was macroscopically suspected in 41 (26%) patients, and 63 (40%) underwent scar resection. SM was confirmed in 19 (30%). Among patients with macroscopic suspicion, 45% had confirmed SM (positive predictive value, PPV). A total of 1 of 23 (4%) patients with no macroscopic suspicion had SM (negative predictive value, NPV = 96%). Among the PMP patients (n = 71), SM was macroscopically suspected in 13 (18%), and 28 (39%) underwent scar resection, of whom 12 (43%) had SM. The PPV was 77%. Occult SM was found in 1 of 14 (NPV = 93%). Not undergoing routine scar resection did not affect recurrence-free survival (RFS, p = 0.2) or overall survival (OS, p = 0.1) in colorectal PM patients or PMP patients (RFS p = 0.7, OS p = 0.7). CONCLUSION Occult SM is uncommon and scar resection does not affect RFS or OS. Therefore, macroscopically benign-appearing scars can be left without resection, though resection should be performed upon suspicion or uncertainty.

Abstract
BACKGROUND CRS-HIPEC provides oncologic benefit in well-selected patients with peritoneal carcinomatosis; however, it is a morbid procedure. Decision tools for preoperative patient selection are limited. We developed a risk score to predict severity of 90 day complications for cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). PATIENTS AND METHODS Adults who underwent CRS-HIPEC at the University of Pittsburgh Medical Center (March 2001-April 2020) were analyzed as part of this study. Primary endpoint was severe complications within 90 days following CRS-HIPEC, defined using Comprehensive Complication Index (CCI) scores as a dichotomous (determined using restricted cubic splines) and continuous variable. Data were divided into training and test sets. Several machine learning and traditional algorithms were considered. RESULTS For the 1959 CRS-HIPEC procedures included, CCI ranged from 0 to 100 (median 32.0). Adjusted restricted cubic splines model defined severe complications as CCI > 61. A minimum of 20 variables achieved optimal performance of any of the models. Linear regression achieved the highest area under the receiving operator characteristic curve (AUC, 0.74) and outperformed the NSQIP Surgical Risk calculator (AUC 0.80 vs. 0.66). Factors most positively associated with severe complications included peritoneal carcinomatosis index score, symptomatic status, and undergoing pancreatectomy, while American Society of Anesthesiologists 2 class, appendiceal diagnosis, and preoperative albumin were most negatively associated with severe complications. CONCLUSIONS This study refines our ability to predict severe complications within 90 days of discharge from a hospitalization in which CRS-HIPEC was performed. This advancement is timely and relevant given the growing interest in this procedure and may have implications for patient selection, patient and referring provider comfort, and survival.

Abstract
Background: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) entails several risk factors for incisional hernia (IH). A few reports available showing incidences between 7% and 17%. At our institution fascia closure has been performed in a 4:1 suture to wound length manner, with a continuous 2-0 polydiaxanone suture (PDS-group) or with a 2-0 polypropylene suture preceded by a reinforced tension line (RTL) suture (RTL-group). Our hypothesis was that these patients might benefit from reinforcing the suture line with a lower IH incidence in this group. The aim was to evaluate the 1-year IH-incidence of the two different closures. Methods: Patients eligible for inclusion were treated with CRS/HIPEC between 2004 and 2019. IH was diagnosed by scrutinizing CT-scans 1 year ±3 months after surgery. Additional data was retrieved from clinical records and a prospective CRS/HIPEC-database. Results: Of 193 patients, 129 were included, 82 in the PDS- and 47 in the RTL-group. RTL-patients were 5 years younger, had less blood loss and more frequent postoperative neutropenia. No difference regarding sex, BMI, recent midline incisions, excision of midline scars, peritoneal cancer index score, complications (≥Clavien-Dindo 3b), or chemotherapy. Ten IH (7.8%) were found, 9 (11%) in the PDS- and 1 (2.1%) in the RTL-group (p = 0.071). Conclusion: An IH incidence of 7.8% in patients undergoing CRS/HIPEC is not higher than after laparotomies in general. The IH incidence in the PDS-group was 11% compared to 2% in the RTL-group. Even though significance was not reached, the difference is clinically relevant, suggesting an advantage with RTL suture.

Abstract
Objectives The impact of insurance status on oncological outcome in patients undergoing cytoreduction and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is poorly understood. Methods Retrospective study on 31 patients having undergone 36 CRS-HIPEC at a single institution (safety-net hospital) between 2012 and 2018. Patients were categorized as insured or underinsured. Demographics and perioperative events were compared. Primary outcome was overall survival (OS). Results A total of 20 patients were underinsured and 11 were insured. There were less gynecologic malignancies in the underinsured (p=0.02). On univariate analysis, factors linked to poor survival included gastrointestinal (p=0.01) and gynecologic malignancies (p=0.046), treatment with neoadjuvant chemotherapy (p=0.03), CC1 (p=0.02), abdominal wall resection (p=0.01) and Clavien–Dindo 3-4 (p=0.01). Treatment with neoadjuvant chemotherapy and abdominal wall resections, but not insurance status, were independently associated with OS (p=0.01, p=0.02 respectively). However, at the end of follow-up, six patients were alive in the insured group vs. zero in the underinsured group. Conclusions In this small, exploratory study, there was no statistical difference in OS between insured and underinsured patients after CRS-HIPEC. However, long-term survivors were observed only in the insured group.

The role of single-incision laparoscopic peritoneal exploration in the management of patients with peritoneal metastases. Surg Endosc 2019; 34:2040-2049. [PMID: 31321535 DOI: 10.1007/s00464-019-06984-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Accepted: 07/15/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND The outcome of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) depends on the extent of peritoneal metastases (PM) and the completeness of cytoreduction (CCR). The role of preoperative assessment of PM is to identify potential candidates for CRS/HIPEC and to prevent unwarranted laparotomy for those who are not. Laparoscopy has been utilized for that purpose but with concerns related to technical difficulties and risk of trocar site metastases. Single-incision laparoscopic peritoneal exploration (SILPE) has not yet been evaluated in this setting. METHODS This single-center retrospective study examined patients from January 2011 to December 2015 who underwent SILPE for diagnosis and staging of PM. Preoperative, intraoperative, and postoperative data were collected. For the patients who underwent subsequent laparotomy, a comparison between SILPE and laparotomy findings was made. RESULTS A total of 183 SILPE were performed. Primary sites were mostly colorectal in 72 cases (39.3%) and gastric in 47 (25.7%). Overall, 157 patients (85.8%) had at least one prior abdominal surgery and 48 (26.2%) had 3 or more. SILPE was successfully achieved in 90.2% of the cases. Two (1.2%) intraoperative complications and five (3%) postoperative complications were observed. Eighty-one patients had laparotomy, with a median of 27 days between SILPE and laparotomy (4-162 days). The peritoneal carcinomatosis index PCI was 9.7 ± 7.5 at SILPE, and 13.5 ± 9.6 at laparotomy. The positive predictive value of SILPE to predict CCR was 79.5%. SILPE sensitivity was 75% and specificity 97%. The lowest sensitivity was in regions 9-12 ranging from 44 to 53%. CONCLUSION SILPE can be safely incorporated in the management of patients with PM. It is a safe and feasible staging tool, allowing for preventing unwarranted laparotomy for patients not deemed candidate for CRS/HIPEC. Even though it may underestimate PCI, SILPE accurately predicts the possibility of CCR.

Abstract
PURPOSE CRS/HIPEC has evolved as an effective method for management of selected patients with peritoneal metastatic disease. Abdominal wall resection (AWR) is often required, and may require complex reconstructions, such as component separation (CST) leading to wound dehiscence (WD) and wound complications (WC). The purpose of our study was to analyse factors contributing to wound complications and wound recurrence (WR). METHODS Retrospective review of a prospective database of 1074 patients undergoing CRS/HIPEC procedures from 1996 to 2017 at St George Hospital. RESULTS AWR and reconstruction for abdominal wall metastases was performed in 197 (18.3%) patients. Tumour types included mesothelioma, appendiceal, colorectal and ovarian cancers. Grade III WC were found in 21 (10.6%). WD was found in 14 (7.1%) compared to 30 (3.4%) in 877 patients without AWR (p = 0.028). Midline WR was seen in 26 (13.3%) with AWR and mean time to recurrence of 18 months. Multivariable' regression analysis showed age (OR 1.06, 95%CI 1.01-1.11, p = 0.022) and CST (OR 9.63, 95%CI 2.55-36.23, p = 0.001) were independent predictors of Grade III WC, and CST (OR 4.19, 95%CI 1.27-13.86, p = 0.019) was an independent predictor of WD after AWR. The presence of a higher prior surgical score (PSS) 2-3 (OR 2.74, 95%CI 1.16-6.49, p = 0.022) was an independent predictor of midline WR post AWR. CONCLUSION This study demonstrates that patients undergoing AWR have a higher incidence of postoperative WD. CST was associated with an increased incidence of Grade III WC and WD. Patients with a higher PSS were more likely to develop midline wound recurrence.

Abstract
Background Patients with peritoneal malignancy often have multiple laparotomies before referral for cytoreductive surgery (CRS). Some have substantial abdominal wall herniation and tumour infiltration of abdominal incisions. CRS involves complete macroscopic tumour removal and hyperthermic intraperitoneal chemotherapy (HIPEC). Abdominal wall reconstruction is problematic in these patients. The aim of this study was to establish immediate and long-term outcomes of abdominal wall reconstruction with biological mesh in a single centre. Methods A dedicated peritoneal malignancy database was searched for all patients who had biological mesh abdominal wall reconstruction between 2004 and 2015. Short- and long-term outcomes were reviewed. All patients had annual abdominal CT as routine peritoneal malignancy follow-up. Results Some 33 patients (22 women) with a mean age of 53·4 (range 19-82) years underwent abdominal wall reconstruction with biological mesh. The majority (23) had CRS for pseudomyxoma (19 low grade), six for colorectal peritoneal metastasis and four for appendiceal adenocarcinoma; 18 had undergone CRS and HIPEC previously. Twenty-five of the 33 patients had abdominal wall tumour involvement and eight had concurrent hernias. The mean duration of surgery was 486 (range 120-795) min and the mean mesh size used was 345 (50-654) cm2. Ten patients developed wound infections and four had a seroma. Two developed early enterocutaneous fistulas. Mean follow-up was 48 months. Five patients developed an incisional hernia. Four died from progressive malignancy. A further 15 patients had disease recurrence, but only one had isolated abdominal wall recurrence. Conclusion Biological mesh was safe and effective for abdominal wall reconstruction in peritoneal malignancy. Postoperative wound infections were frequent but nevertheless incisional hernia rates were low with no instances of mesh-related bowel erosion or fistulation.

Abstract
BACKGROUND Cytoreduction surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) improve survival and decrease recurrence of peritoneal metastasis in a select population of patients. Abdominal wall resection is often needed to achieve complete CRS and the extent of abdominal wall resection may necessitate abdominal wall reconstruction (AWR). We sought to investigate if postoperative morbidity and mortality was increased in patients who underwent AWR with CRS-HIPEC (AWR group) compared to CRS-HIPEC without AWR (non-AWR group) and to identify if patient, tumor, and operative risk factors were associated with poor outcomes following AWR. We postulate that AWR is a safe and viable treatment option in appropriately selected patients with peritoneal disease. METHODS A retrospective chart review was conducted from 2012 to 2015. Demographics, comorbidities, intraoperative variables, and postoperative outcomes were analyzed and compared between the non-AWR group and the AWR group. RESULTS A total of 30 patients underwent CRS-HIPEC at our institution; 19 recruited in non-AWR group and 11 in the AWR arm. Median follow-up was 19.1 mo for the non-AWR group and 15.6 mo for AWR. Overall survival and complications were not significantly different between groups. Six patients in the non-AWR group and three patients in AWR group died during the follow-up period (32% versus 27%, P = 0.75). Grade III/IV Clavien-Dindo complications were similar in AWR compared to non-AWR group (64% versus 50%, P = 0.46) however estimated blood loss (1000 mL versus 450 mL, P = 0.01) and operative time (663 min versus 510 min, P = 0.02) were significantly increased in the AWR group. CONCLUSIONS The results of this study demonstrate that AWR is a safe and viable option and can improve wound closure and strength in select patient populations undergoing CRS-HIPEC. AWR is not associated with an increase in mortality or complication rate. Future studies will need larger sample sizes and randomization to identify patient and operative factors that increase morbidity with AWR and identify the ideal timing of AWR.

Abstract
Background Peritoneal surface malignancies (PSMs) are usually staged using Sugarbaker’s Peritoneal Cancer Index (PCI) and completeness of cytoreduction score (CC-s). Although these staging tools are essential for selecting patients and evaluating outcome after cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), both scoring models lack some anatomic information, thus making staging laborious and unreliable. Maintaining Sugarbaker’s original concepts, we therefore developed a computerized digital tool, including a new anatomic scheme for calculating PCI and CC-s corresponding closely to patients’ real anatomy. Our new anatomic model belongs in a web-based application known as the PSM Staging System, which contains essential clinical and pathological data for the various PSMs currently treated. Methods The new digital tool for staging PSM runs on a personal computer or tablet and comprises male and female colored anatomic models for the 13 endoabdominal regions, with borders defined according to real anatomic landmarks. A drag-and-drop tool allows users to compute the PCI and CC-s, making it easier to localize and quantify disease at diagnosis and throughout treatment, and residual disease after CRS. Conclusions Once tested online by registered users, our computerized application should provide a modern, shareable, comprehensive, user-friendly PSM staging system. Its anatomic features, along with the drag-and-drop tool, promise to make it easier to compare preoperative and postoperative PCIs, thus improving the criteria for selecting patients to undergo CRS plus HIPEC. By specifying the size, site, and number of residual lesions after CRS plus HIPEC, our digital tool should help stratify patients into outcome classes.
