A Systematic Review on the Efficacy of Cytoreductive Surgery and Perioperative Intraperitoneal Chemotherapy for Pseudomyxoma Peritonei

Background The efficacy of cytoreductive surgery (CRS) combined with perioperative intraperitoneal chemotherapy (PIC) for patients with pseudomyxoma peritonei (PMP) remains to be established. Methods Searches for all relevant studies prior to March 2006 were performed on six databases. Two reviewers independently appraised each study using a predetermined protocol. The quality of each study was assessed. Clinical effectiveness was synthesized through a narrative review with full tabulation of results of all included studies. Results Ten most recent updates from each institution were included for appraisal and data extraction. There were no randomized controlled trials or comparative studies. All included articles were observational studies without control groups. Five studies were relatively large series (n≥100). Two studies had relatively long-term follow-up (48 months and 52 months). The median follow-up in the remaining eight studies was shorter than 3 years (range 19–35 months). The median survival ranged from 51 to 156 months. The 1-, 2-, 3- and 5-year survival rates varied from 80 to 100%, 76 to 96%, 59 to 96% and 52 to 96%, respectively. The overall morbidity rate varied from 33 to 56%. The overall mortality rates ranged from 0 to 18%. Conclusions This study reviewed current evidence on CRS and PIC for PMP. Only observational studies were available for evaluation, which demonstrated some promising long-term results, as compared to historical controls. Due to the rarity of this disease, a well-designed prospective multi-institutional study would be meaningful.     

Progression of Pseudomyxoma Peritonei after Combined Modality Treatment: Management and Outcome

Background Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a treatment strategy for pseudomyxoma peritonei (PMP) with curative intent. The aim of this study was to determine the patterns of failure in patients who underwent such a procedure and to evaluate management and outcome of progressive disease. Methods After exclusion of patients with overt malignancy, progression was studied in 96 PMP patients treated primarily by CRS with HIPEC. Location, pathology, management and outcome were recorded. Results Median follow-up was 51.5 months (0.1–99.5). Median progression free survival (PFS) was 28.2 months (95% CI 18.3->). Progressive disease was mainly located sub hepatic (38%) or in multiple regions (36%). Pathological dedifferentiation was observed in 8 patients (20%). The choice of treatment depended on pathology, extent of disease and PFS. Seventeen patients were treated for progression by second CRS with (n=8) or without HIPEC (n=10). The 3-years overall survival (OS) probability after this treatment was 100% and 53.3% (95% CI 28.2–100%), respectively. Fifteen patients with (slow) progression were observed. Three-years OS probability of these patients was 66.0% (95% CI 43.4–100%). All patients treated for progression by systemic chemotherapy only (n=6) had died of disease after a median follow up of 14.8 (9.8–33.6) months. A longer PFS after primary treatment was associated with longer OS after progression (P = 0.04). Conclusions Progressive PMP after primary CRS with HIPEC is probably the result of technical failure and/or tumor biology. Management of progressive PMP can be valuable for selected patients and should depend primarily on the PFS.     

Survival analysis of pseudomyxoma peritonei patients treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

OBJECTIVE: To evaluate the survival of patients with pseudomyxoma peritonei (PMP) treated by cytoreductive surgery and intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC), and to identify factors with prognostic value. SUMMARY BACKGROUND DATA: PMP is a clinical syndrome characterized by progressive intraperitoneal accumulation of mucous and mucinous implants, usually derived from a ruptured mucinous neoplasm of the appendix. Survival is dominated by pathology. METHODS: A total of 103 patients (34 men and 69 women) treated at The Netherlands Cancer Institute between 1996 and 2004 were identified. Survival was calculated from date of initial treatment and corrected for a second procedure. PMP was pathologically categorized into disseminated peritoneal adenomucinosis (DPAM), peritoneal mucinous carcinomatosis (PMCA), and an intermediate subtype (PMCA-I). Clinical and pathologic factors were analyzed to identify their prognostic value for survival. RESULTS: Median follow-up was 51.5 months (range, 0.1-99.5 months). Recurrence developed in 44%. A second procedure for recurrence was performed in 11 patients. The median disease-free interval was 25.6 months (95% confidence interval [CI], 14.8-43.6 months). The 3-year and 5-year disease-free survival probability was 43.6% (95% CI, 34.4%-55.2%) and 37.4% (95% CI, 28.2%-49.5%), respectively. The disease-specific 3-year and 5-year survival probability was 70.9% (95% CI, 62.0%-81.2%) and 59.5% (95% CI 48.7%-72.5%), respectively. Factors associated with survival were pathological subtype, completeness of cytoreduction, and degree and location of tumor load (P < 0.05). The main prognostic factor, independently associated with survival, was the pathologic subtype (P < 0.01). CONCLUSION: Cytoreductive surgery in combination with intraoperative HIPEC is a feasible treatment strategy for PMP in terms of survival. The pathologic subtype remains the dominant factor in survival. Patients should be centralized to improve survival by a combination of surgical experience and adequate patient selection.

Systematic Review on the Efficacy of Multimodal Treatment of Sarcomatosis with Cytoreduction and Intraperitoneal Chemotherapy

Background

Peritoneal sarcomatosis carries a dismal prognosis with median survival of 12 months and no 5-year survivors. The treatment for sarcomatosis has mostly been chemotherapy and surgery for palliation. Recently, cytoreduction (CRS) and intraperitoneal chemotherapy (IPC) has been tried as an alternative for improving regional control and survival, but the efficacy of this combined treatment is difficult to determine. The objective of this review is to evaluate all available evidence to determine the efficacy of this treatment modality.

Materials and Methods

Searches for studies published in peer-reviewed journals before October 2010 were carried out on 3 databases. The reference lists of all identified articles were reviewed for further relevant studies. Relevant studies were then evaluated by 3 investigators, and the quality of each study was assessed. Studies that met an established criterion were reviewed for clinical effectiveness with a tabulation of all results.

Results

Eight prospective and one randomized trial were available representing 240 patients treated with CRS and IPC. The median disease-free survival ranged from 2.3 to 22 months, median survival ranged from 5.5 to 39.6 months, and the 5-year survival ranged from 7% to 65%. The surgical morbidity varied from 9% to 44% and the mortality from 0% to 11%.

Conclusions

Based on the available data, this treatment approach is currently not recommended in the treatment of sarcomatosis except in experienced centers, in well-selected patients and as part of an experimental protocol.     

Survival after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases: A systematic review and discussion of latest controversies

IntroductionPeritoneal metastases confer the worst survival amongst all sites of metastatic colorectal cancer. The adoption of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has become an option for patients with isolated colorectal peritoneal metastases (CRPM). The aim of this study was to evaluate the outcomes following CRS and HIPEC for CRPM from published high volume cohort studies and to highlight the latest controversies and future directions of CRPM treatment.Materials and methodsA systematic review was performed on published studies on the treatment outcomes of CRS and HIPEC for colorectal peritoneal metastases.ResultsTwenty studies met the inclusion criteria for the systematic review. The median survival for all patients ranged from 14.6 to 60.1 months. The 5-year overall survival ranged from 23.4% to 52%. For patients with complete cytoreduction, the median survival was 25 to 49 months. Major morbidity and mortality ranged from 15.1% to 47.2% and 0% to 4.5%, respectively.ConclusionCRS and HIPEC for the treatment of CRPM is safe and current evidence suggests it improves both median and disease-free survival. However, the efficacy of intraperitoneal chemotherapy, in particular oxaliplatin, has recently come under scrutiny. Accordingly, higher quality evidence is urgently required to contribute to multidisciplinary and international consensus on CRPM treatment strategies.     

Approach to pseudomyxoma peritonei

Pseudomyxoma peritonei(PMP) is a mucinous tumour of the appendix that spreads into the peritoneal cavity in the form of gelatinous deposits. The incidence of PMP is believed to be approximately 1-3 out of a million per year. Nonetheless, due to its indolent nature, it is usually discovered at an advanced stage and severely impacts quality of life. Curative treatment for PMP is complete cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC). An extensive literature review was conducted searching EMBASE, MEDLINE, Pub Med, and Google Scholar databases for PMP in aims to delineate a clinical approach to diagnosis and treatment. Literature was limited to the years 2007-2018. We found the 5-year overall survival with CRS and HIPEC estimated to be between 23%-82% and rates of major complications as high as 24%. Therefore, it is important to appropriately stage and select patients that should undergo CRS with HIPEC. Modalities like MDCT radiological scores have been shown to have sensitivity and specificity of 94% and 81%, respectively, in being able to predict resectability and survival. Despite treatment, the disease often recurs. Tumor markers have significant potential for establishing prognosis preoperatively, and this paper will review the most recent evidence in support of them.     

Cytoreduction and HIPEC in The Netherlands: Nationwide Long-term Outcome Following the Dutch Protocol

Purpose

This nationwide study evaluated results of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal metastasis of colorectal origin in the Netherlands following a national protocol.

Methods

In a multi-institutional study prospective databases of patients with peritoneal carcinomatosis (PC) from colorectal cancer and pseudomyxoma peritonei (PMP) treated according to the Dutch HIPEC protocol, a uniform approach for the CRS and HIPEC treatment, were reviewed. Primary end point was overall survival and secondary end points were surgical outcome and progression-free survival.

Results

Nine-hundred sixty patients were included; 660 patients (69 %) were affected by PC of colorectal carcinoma and the remaining suffered from PMP (31 %). In 767 procedures (80 %), macroscopic complete cytoreduction was achieved. Three-hundred and thirty one patients had grade III–V complications (34 %). Thirty-two patients died perioperatively (3 %). Median length of hospital stay was 16 days (range 0–166 days). Median follow-up period was 41 months (95 % confidence interval (CI), 36–46 months). Median progression-free survival was 15 months (95 % CI 13–17 months) for CRC patients and 53 months (95 % CI 40–66 months) for PMP patients. Overall median survival was 33 (95 % CI 28–38 months) months for CRC patients and 130 months (95 % CI 98–162 months) for PMP patients. Three- and five-year survival rates were 46 and 31 % respectively in case of CRC patients and 77 and 65 % respectively in case of PMP patients.

Conclusions

The results underline the safety and efficacy of cytoreduction and HIPEC for PC from CRC and PMP. It is assumed the uniform Dutch HIPEC protocol was beneficial.     

Preoperative Carcinoembryonic Antigen Level Predicts Prognosis in Patients with Pseudomyxoma Peritonei Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy

Background

Even though management of pseudomyxoma peritonei (PMP) was improved with cytoreductive surgery (CRS) and hyperthermic chemotherapy (HIPEC), several aspects of PMP still need to be optimized, including patient selection for surgery and prognostic factors. We assessed the role of preoperative carcinoembryonic antigen (CEA) levels in PMP patients treated with CRS and HIPEC.

Methods

A total of 449 PMP patients with documented preoperative CEA levels referred to our center between 2005 and 2011 underwent CRS and HIPEC. The association between CEA levels and characteristics of patients with PMP was assessed with χ ² test, linear correlation, and logistic regression analyses. Survival analysis was performed with Cox proportional hazard model.

Results

Median age was 55 (range 19–84) years. There were 245 (54.5 %) females and 204 (45.5 %) males. Preoperative CEA levels were elevated in 328 (73 %, sensitivity) patients with PMP. Preoperative CEA levels were also related to peritoneal cancer index (P < 0.0001), cytoreductive surgery scores (P < 0.0001), progress free survival (P < 0.001) and overall survival (P < 0.001) in patients with PMP.

Conclusions

Our results indicated that preoperative CEA levels are useful in predicting the extent of disease and surgical success as well as progress-free and overall survival in patients with PMP treated with cytoreductive surgery and HIPEC.
