Received 1 March Published 30 June Volume Peer reviewers approved by Dr Lucy Goodman. Editor who approved publication: Cytoreductive surgery CRS and hyperthermic intraperitoneal chemotherapy HIPEC is a viable option for selected patients with peritoneal metastases PM from colorectal origin, resulting in long-term survival and even cure in some cases.

However, adequate patient selection for this treatment is currently one of the sugqrbaker challenges. The aim of this review is to provide a comprehensive overview of clinically relevant factors associated with overall survival.

This may help to guide clinicians through the complex interplay of patient, tumor, and treatment characteristics to adequately select patients who benefit the most from this extensive surgical treatment.

According to available literature, especially extent of peritoneal sugarbker, completeness of cytoreduction, and signet ring cell histology have great influence on the outcome after CRS and HIPEC.

Other factors that seem to have a negative prognostic value are the presence of liver metastases and the absence of treatment with neo-adjuvant systemic therapy. Prognostic models combining the above-mentioned factors, such as the Colorectal Peritoneal Metastases Prognostic Surgical Score nomogram, may provide clinically relevant tools to use in everyday practice.

One of the major challenges is adequate sugarbakwr selection for this procedure.

This review aims to give a comprehensive overview of this disease and its treatment, with special emphasis hkpec patient selection. Therefore, the most important prognostic factors will be discussed according to available literature.

This review will help to guide sugarbakeg through a complex interplay of patient, tumor, and sugarbakeg characteristics to adequately select patients who benefit the most from this extensive surgical treatment. Colorectal cancer is the fourth most prevalent type of cancer and ranks second in the absolute number of estimated cancer deaths in the United States.

PM, commonly referred to as peritoneal carcinomatosis, are metastatic deposits on the peritoneal surface throughout the abdominal cavity. These deposits may invade abdominal organs and structures, thereby frequently causing bowel obstruction, ureteral obstruction, and malignant ascites. PM may arise from virtually every primary tumor, with the most common origins being ovarian cancer in females and colorectal cancer in males.

This condition is characterized by mucinous ascites and mucinous peritoneal implants, which most often originate sufarbaker a ruptured low-grade mucocele of the appendix. In summary, PM may originate from various underlying diseases with a large variation in epidemiology, treatment strategy, and prognosis. This review will solely discuss the treatment of patients with PM from colorectal origin. Lemmens et al have identified an advanced T stage, lymph node metastases, and a poor differentiation grade as independent risk factors for synchronous PM.

One of the most promising subjects of future research is the prevention of suagrbaker colorectal PM. Although results were sugarabker, a recent systematic review pointed toward promising results of adjuvant intraperitoneal chemotherapy in colorectal cancer patients at high risk of PM.

Chemo Controversy: An Inside Look at the ‘Hot Chemotherapy Bath’

For many decades, there has been little interest in investigating the treatment of colorectal PM, mainly due to the rapid progression of the disease and the lack of curative options. Curative intent surgery played a minor role in the treatment, which sugarbakr focused on symptom relief.

The efficacy of palliative systemic chemotherapy for colorectal PM remains less evident than its efficacy for other colorectal cancer metastases. Based on the hypothesis that colorectal PM are a locoregional disease, a new surgical technique was first described in and further introduced by Paul Sugarbaker in the early s.


First, all macroscopically visible tumor tissue is removed from the peritoneal surface by performing both peritoneal and visceral resections. This part sugarbaksr called CRS. The randomized controlled trial by Cashin et hjpec was terminated prematurely due to recruitment difficulties. Nevertheless, with 24 patients in each arm a significant survival benefit was found in patients treated with CRS and HIPEC compared to patients treated with oxaliplatin-based chemotherapy.

Because sugaebaker difficulties in conducting more randomized controlled trials, the hipex practice is mainly based on large retrospective cohort studies. These multicenter analyses reported median overall survival rates of up to 63 months in highly selected patients successfully treated with CRS and HIPEC. Although CRS and HIPEC is the standard of care in selected patients with colorectal PM in several countries, various clinical issues urgently need to be optimized to improve the outcome for these patients.

Probably, the most important and evident prognostic hupec is the extent of peritoneal disease. Although several scoring systems exist, the peritoneal cancer index PCI score is the most commonly used and best validated.

Furthermore, a closely related factor is the extent of small bowel involvement. Computed tomography CT sugagbaker a low sensitivity and specificity for detection of PM, and the radiological extent of peritoneal disease does not adequately correlate with the intraoperative PCI score. So far, diagnostic laparoscopy with histological confirmation remains the gold standard for diagnosing and quantifying colorectal PM, despite its more invasive character.

The completeness of cytoreduction score measures the amount of sugarbakrr visible tumor that is seen after CRS. Completeness of cytoreduction is so essential that experts agree that CRS and HIPEC should only be performed if complete or nearly complete macroscopic cytoreduction is feasible.

The development of intraoperative fluorescence imaging techniques for detecting PM provides interesting possibilities for more effective cytoreduction. The general concept of these techniques is to combine a tumor-specific antibody with a fluorescence probe, thus enabling intraoperative sugagbaker of tumor spots with near-infrared light.

Several preclinical studies showed that these techniques have great potential for detecting PM. For a long sugwrbaker, patients with combined peritoneal and liver metastases were nipec treated with curative intent, which at least partly attributed to the poor population-based median survival of 5 months.

In these patients, a recently updated review of clinically heterogeneous studies revealed a median overall survival that ranged from 6 to 49 months, which was lower sugarbakfr in patients with isolated PM in most of the included studies.

In conclusion, a patient tailored approach in patients with both peritoneal and liver metastases may result in long-term survival with acceptable morbidity. Nevertheless, survival seems to be slightly diminished compared to patients with isolated PM. Elias et al developed a tumor load-based nomogram to predict survival prior to optimal surgery in these patients, which might be of value in the complex process of decision making for this intensive treatment.

Additionally, several studies that focused on prognostic factors identified signet ring cell histology as an important negative factor with hazard ratios ranging from 2. Nevertheless, with respect to palliative care, a similar relative survival gain can be achieved by CRS and HIPEC in patients with signet ring cell histology compared with patients with adenocarcinomas and mucinous adenocarcinomas.

Since patients with these carcinomas are often young, an aggressive surgical approach may be a realistic option in a highly selected subgroup. In non-metastasized patients, colon and rectal cancer are considered as separate entities with a different treatment hiped prognosis. Colorectal PM are often considered as one disease, regardless of their colon or rectal origin. As a result, skgarbaker large group of colon cancer patients often camouflages the results of the small portion of rectal cancer patients.

Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Methodology, Drugs and Bidirectional Chemotherapy

The value of neo-adjuvant systemic therapy remains controversial due to an absence of randomized studies. Several retrospective observational studies analyzed survival outcomes of patients who were stratified for neo-adjuvant versus no neo-adjuvant systemic therapy. Hypothetically, neo-adjuvant systemic therapy may increase the chance of achieving a complete cytoreduction by preoperative tumor downsizing. However, a pooled subgroup analysis of randomized studies in advanced colorectal cancer endorses the dogma that colorectal PM are relatively resistant to systemic therapy compared to other isolated sites of metastases.


Results of these studies will provide more insight in the sensitivity of colorectal PM to modern neo-adjuvant chemotherapy with targeted agents.

Besides preoperative tumor downsizing, improved patient selection is another potential and more commonly accepted advantage of neo-adjuvant systemic therapy.

It may be postulated that patients with disease progression upon neo-adjuvant systemic therapy do not benefit from CRS and HIPEC due to aggressive tumor biology. A French study reported an impressive median overall survival of 63 months in selected patients who received CRS and HIPEC after they revealed a favorable tumor response upon neo-adjuvant systemic therapy. For example, an intention-to-treat analysis in resectable colorectal liver metastases revealed no overall survival difference of perioperative systemic therapy and surgery compared to upfront surgery.

Taken together, neo-adjuvant systemic therapy may improve survival after CRS and HIPEC by improving patient selection, but its benefit on an intention-to-treat basis needs to be confirmed by results of ongoing and future studies. Ideally, these factors are combined in a prognostic model to predict survival of colorectal PM patients treated with curative intent.

Indeed, several prognostic scores have been published. Verwaal et al were the first to combine location of the primary tumor, histological subtype, and extent of peritoneal disease into a prognostic model. The development study only included 40 patients and did not seem to use regression coefficients to determine the weighed scores. Several multi-institutional studies evaluated the prognostic value of PSDSS and agreed that it has some predictive value. This Cox regression-based nomogram included four factors: This review focused on several important issues in this complex interplay of patient, tumor, and treatment characteristics.

The presence of liver metastases seems to have a negative prognostic impact.

Additionally, rectal cancer should not be regarded as a strong negative prognostic factor. In general, only patients with limited peritoneal disease, eligible for complete macroscopic cytoreduction and without signet ring cell histology, are able to achieve long-term survival after CRS and HIPEC. Prognostic models combining the above-mentioned factors, such as the COMPASS nomogram, may provide clinically relevant tools to use in everyday practice.
