The impact of PRODIGE 7 on the current worldwide practice of CRS-HIPEC for colorectal peritoneal metastases: A web-based survey and 2021 statement by Peritoneal Surface Oncology Group International (PSOGI).

Introduction: The PRODIGE 7-trial investigated the additional value of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) to cytoreductive surgery (CRS) for patients with colorectal peritoneal metastases (CPM). The results of PRODIGE 7 were presented at the 2018 ASCO meeting showing that 30 min oxaliplatin-based HIPEC did not improve overall survival. The current study investigated the impact of PRODIGE 7 on the worldwide practice of CRS and HIPEC.

Iterative cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases: A multi-institutional experience.

Background And Objectives: The aims of this multi-institutional study were to assess the feasibility of iterative cytoreductive surgery (iCRS)/hyperthermic intraperitoneal chemotherapy, iCRS in colorectal peritoneal carcinomatosis (CRPC), evaluate survival, recurrence, morbidity and mortality outcomes, and identify prognostic factors for overall survival.

Methods: Patients with CRPC that underwent an iCRS, with or without intraperitoneal chemotherapy, from June 1993 to July 2016 at 13 institutions were retrospectively analyzed from prospectively maintained databases.

Results: The study comprised of 231 patients, including 126 females (54.

Effects of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in the Treatment of Goblet Cell Carcinoma: A Prospective Cohort Study.

Background: Goblet cell carcinoma (GCC) of the appendix is a rare disease. Treatment options vary according to disease staging. Cytoreductive surgery in combination with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) may improve survival in patients with peritoneal spreading.

Short-term outcome in patients treated with cytoreduction and HIPEC compared to conventional colon cancer surgery.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an extensive procedure with considerable morbidity. Since only few hospitals perform CRS + HIPEC, this might lead to confounded outcomes between hospitals when audited. This study aims to compare outcomes between peritoneally metastasized (PM) colon cancer patients treated with CRS + HIPEC and patients undergoing conventional colon surgery.

Peritoneal metastases from small bowel cancer: Results of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in The Netherlands.

Introduction: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) is currently considered the standard of care for pseudomyxoma peritonei, mesothelioma and peritoneal metastases (PM) from colorectal cancer. CRS + HIPEC has also been suggested as a potential treatment option in PM of the much rarer small bowel cancer. Therefore, the current study was undertaken to investigate the results of CRS + HIPEC in all HIPEC centers in The Netherlands.

Tumour regression grading after chemoradiotherapy for locally advanced rectal cancer: a near pathologic complete response does not translate into good clinical outcome.

Background: After preoperative chemoradiotherapy (CRT) for rectal cancer, clinically undetectable residual tumour deposits or pathologic lymph nodes may remain in the mesorectum.

Aim: The aim of this study was to report histopathological effects of CRT and factors affecting outcome in a uniformly treated series of locally advanced rectal cancer (LARC) patients.

Methods: Between 2004 and 2008, 107 patients with cT3 (threatening the mesorectal fascia or <5 cm from the anal verge), cT4 or cN2 rectal cancer were treated with preoperative CRT (25 × 2 Gy with capecitabine) and TME 6-8 weeks later.

Imagine a world without cancer.

Background: Since the "War on Cancer" was declared in 1971, the United States alone has expended some $300 billion on research, with a heavy focus on the role of genomics in anticancer therapy. Voluminous data have been collected and analyzed. However, in hindsight, any achievements made have not been realized in clinical practice in terms of overall survival or quality of life extended.

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.

Peritoneal carcinomatosis: cytoreductive surgery and HIPEC--overview and basics.

Tumor involvement of the peritoneum-peritoneal carcinomatosis-is a heterogeneous form of cancer that had been generally regarded as a sign of systemic tumor disease and as a terminal condition. The multimodal treatment approach for patients with peritoneal carcinomatosis, which had been conceived and developed, consists of what is known as cytoreductive surgery, followed by hyperthermic intraperitoneal chemotherapy (HIPEC). Depending on the tumor mass as assessed intraoperatively and the histopathological differentiation, patients who undergo cytoreductive surgery and HIPEC have a significant survival benefit.

Predictors and survival of synchronous peritoneal carcinomatosis of colorectal origin: a population-based study.

The aim of our study was to provide population-based data on incidence and prognosis of synchronous peritoneal carcinomatosis and to evaluate predictors for its development. Diagnosed in 1995-2008, 18,738 cases of primary colorectal cancer were included. Predictors of peritoneal carcinomatosis were analysed by multivariable logistic regression analysis.

Long-term results of cytoreduction and HIPEC followed by systemic chemotherapy.

Cytoreduction followed by hyperthermic intraperitoneal chemotherapy is a treatment option for peritoneal surface malignancies in The Netherlands. This treatment has been available for more than 10 years. Therefore, long-term results on survival and quality of life can now be studied.

The eligibility for local-regional treatment of peritoneal surface malignancy.

At the Fifth International Workshop on Peritoneal Surface Malignancy, held in Milan, the consensus on technical aspects of cytoreductive surgery (CRS) for peritoneal surface malignancy was obtained through the Delphi process. General conflicting points concerning the eligibility to the local-regional therapy were discussed and voted.

8-year follow-up of randomized trial: cytoreduction and hyperthermic intraperitoneal chemotherapy versus systemic chemotherapy in patients with peritoneal carcinomatosis of colorectal cancer.

Introduction: The treatment of peritoneal carcinomatosis is based on cytoreduction followed by hyperthermic intraperitoneal chemotherapy and combined with adjuvant chemotherapy. In 2003, a randomized trial was finished comparing systemic chemotherapy alone with cytoreduction followed by hyperthermic intraperitoneal chemotherapy and systemic chemotherapy. This trial showed a positive result favoring the studied treatment.
