1. Research Background 
Colorectal cancer (CRC) is the most common malignant tumor of the digestive system in 
the world. Its incidence rate ranks third, and its mortality rate ranks second[1]. The recurrence 
and metastasis of tumor is the leading cause of death in patients with colorectal cancer. 
Peritoneal[2] carcinomatosis (PC) is the most important causes of death in colorectal cancer 
patients after liver metastasis. Studies have shown that the 3-year peritoneal metastasis rate of 
pT4 colorectal cancer is as high as 20-36.7% [3-4]. Prevention of peritoneal metastasis is a 
research hotspot in the treatment of colorectal cancer. 
Sugarbaker et al. used cytoreductive surgery (CRS) combined with hyperthermic 
introperitoneal chemotherapy (HIPEC) for colorectal cancer peritoneal metastasis in the 
1990s. After more than 20 years of clinical practice since the 1990s, it has been proved to 
extend the median survival time and improve the quality of life of patients. [5] 
Intraperitoneal chemotherapy drugs need to meet the following characteristics: First: be 
effective for systemic chemotherapy of colorectal cancer; second, consistent with the 
characteristics of intraperitoneal chemotherapy, which means the drug must be able to kill 
tumor cells through itself or other metabolites effectively, higher intraperitoneal concentration, 
Lower peritoneal permeability, less peritoneal irritation, and stronger tumor tissue penetration 
ability [6]. So far, there are many types of drugs, dosage, time, and drug combination for 
intraperitoneal medication, and there is no unified conclusion. The application of standardized 
clinical intraperitoneal medication has become an urgent key issue [7]. Therefore, studying the 
safety and effectiveness of different chemotherapeutic drugs for HIPEC treatment of 
colorectal cancer is of great significance for improving the survival rate and quality of life of 
patients with advanced colorectal cancer. 
According to the latest domestic expert consensus, the commonly used drugs for HIPEC 
treatment of colorectal cancer are mitomycin, oxaliplatin and 5-fluorouracil [8]. Mitomycin 
(MMC) and oxaliplatin are the most common drugs in international HIPEC. Meta-analysis 
shows that about 21% of patients receiving MMC treatment have serious complications, while 

  
 
11 
 
the rate in the oxaliplatin group is 30%. MMC is safer than oxaliplatin during the HIPEC 
treatment [9]. 
Platinum drugs and mitomycin are cell cycle non-specific antitumor drugs that act on the 
chemical structure of DNA. Oxaliplatin is unstable in sodium chloride solution, so the 
perfusion fluid generally used is glucose or a mixture of glucose and distilled water. Studies 
have shown that the use of glucose in intraperitoneal hyperthermic infusion chemotherapy 
increases the risk of intraoperative hyperglycemia and postoperative infection [10]. Lobaplatin 
is a third-generation platinum drug. It has no obvious nephrotoxicity, ototoxicity, 
neurotoxicity, mild gastrointestinal toxicity, and no cross-resistance with other platinum drugs. 
The perfusion fluid can be normal saline. Single-center preventive studies have shown that 
lobaplatin does not increase the occurrence of postoperative complications during 
intraperitoneal lavage and it has no significant effect on bone marrow suppression, liver and 
kidney function, which means it has good safety [11]. There has been a clinical study registered 
on Clinical Trials to explore the safety of lobaplatin for the treatment of colorectal cancer 
HIPEC (NCT03221608). 
At present, there are few domestic and international clinical studies of HIPEC treatment 
for colorectal cancer. But there is only one prospective randomized controlled trial registered 
on Clinical Trials to evaluate colorectal cancer intraperitoneal hyperthermic perfusion 
chemotherapy (NCT02965248). In this study, randomized controlled experiments were 
conducted to explore the choice of clinical drugs for colorectal cancer and their safety and 
effectiveness to provide references for clinical treatment. 
2. Research purposes 
2.1 Main purpose

12 
 
2.2 Secondary purpose 
Compare the blood routine, biochemical, immunological and ascites related tests before 
and after HIPEC, and analyze the evaluation value of related laboratory test results for

experienced in intraperitoneal hyperthermic perfusion. 
5.2 the selection of patient 
The patients were enrolled continuously according to their willingness to participate in 
the study and the source of the research subjects (inpatients with colorectal cancer). For 
patients who may participate in this registration study, the possibility of enrollment should be 
discussed with the patients. When the patient agrees, the investigator should confirm that the 
patient meets all the inclusion criteria and does not meet any exclusion criteria. Patients who

6.9 Study Endpoint 
Primary study endpoint: overall survival (OS) and peritoneal metastasis-free survival 
(pRFS) was observed for 3 years 
Secondary observation endpoint: the incidence of postoperative adverse reactions (refer 
to CTCAE5.0 (including blood routine, liver and kidney function, patient's reaction to HIPEC, 
adverse events), completed when the patient is discharged. (immunology, ascites) 
If the research subject completes all phases of the research and follow-up or withdraws 
the informed consent according to the research plan, the research end point is reached. 
6.10 Sample size calculation 
Based on the above research background, we estimate that the 3-year expected survival 
rate of patients in the control group is 60%, and the 3-year expected survival rate of patients 
in the experimental group is 80%. This study is expected to complete all surgical treatments in 
one year, and the dropout rate is 5% 

  
 
20 
 
The survival rate of the control group is 0.6, and the survival rate of the intervention 
group is 0.8. Setting the α level to 0.1 and β to 0.2, the power (1-β) is 90%. 
2. P0=0.6, P1=0.8, the two-sided test Zα is 1.645, Zβ is 0.842, bring it into the formula 
 
The theoretical total sample size is 192 persons (64 persons per group) 
3.Considering the falling off of 5% 
A total of 201 people (67 people per group) 
201 people are needed 
6.11 Compliance 
The researcher made a detailed record of the measurement results of each subject, and 
the subjects who actively cooperated in each measurement were deemed to have good 
compliance. Subjects who do not cooperate to complete all measurements are considered to 
have poor compliance. 
6.12 Dose adjustment and medication combined during chemotherapy 
Other chemotherapy and targeted drugs are not allowed before the patient’s disease 
progressing; use phenytoin, carbamazepine, rifampicin, barbiturate, itraconazole and other 
liver enzyme inducers with caution; the use of Chinese medicine for relief Symptoms of 
palliative treatment drugs is allowed (such as analgesics, antiemetics, bisphosphonates, etc.); 
white blood cell therapy can be used according to specific conditions.

1. Dose adjustment method at the beginning of each treatment course: The following table 
shows the dosage adjustment when using radiotherapy and chemotherapy drugs to produce 
hematological toxicity. If the patient has an absolute neutrophil count> 1.5×109/L and a 
platelet count> 100×109/L before starting a course of treatment, a new course of 2 weeks can 
be started without dose adjustment. Otherwise, adjust the dose or delay the treatment until the 
hematological parameters return to the above-mentioned level. If the above hematological 
parameters have not returned to the above levels after the 3 weeks delay in administration, the 
patient should terminate the treatment. 
2. The method of dose adjustment caused by severe hematology DLT: Dose limiting 
toxicity (DLT), including degree 3 and degree 4 hematology toxicity, with or without fever. If 
an unscheduled evaluation during a course of treatment shows dose-limiting toxicity (DLT), 
then capecitabine should be discontinued during the course of treatment, and the dose of 
ticgio and oxaliplatin should be reduced in the next course of treatment, and the dose 
reduction plan as follows. 
≥ 1.5  
And  
≥ 100

at 75% of starting dose of chemotherapeutic 
agents; if absolute neutrophil count recovers 
to ≥ 1.5, then chemotherapeutic agents

8.3.2 Quality of life scoring methods  
The QLQ-C30 (V3.0) of the EORTC is a core scale oriented to all cancer patients, with 
a total of 30 items. Among them, items 29 and 30 are divided into seven levels, which are 
scored from 1 to 7 according to their response options; other items are divided into four 
levels: not at all, a little, a lot, and very, which are directly scored from 1 to 4.  
Calculation of EOETC QLQ-C30 domain (dimension) score (crude score):  
For the convenience of statistical analysis and application, scales are often divided into 
certain domains. Domain is an aspect of the quality of life component, also known as 
dimension, which is analyzed as an independent variable. 30 items of EOETC QLQ-C30 
(V3.0), which can be divided into 15 domains and count 5 functional domains  
(physical, role, cognitive, emotional, and social functioning) 3 symptom domains 
(fatigue, pain, nausea and vomiting), 1 global health status/quality of life domain, and 6 
single items (each as a domain). See the table below for classification.  
The score of each domain is obtained by summing the scores of the included items and 
dividing by the number of included items (crude RS, Raw Score), i.e. RS = (Q1 + Q2 +... + 
Qn )/n.  
Calculation of EOETC QLQ-C30 score  
In order to make the scores of each domain compare with each other, the linear 
transformation is further performed using the polarization method to convert the crude score 
into a standardized score (SS) taking values within 0 ~ 100. In addition, the transformation 
has another purpose, that is, to change the direction of the score. Because the QLQ-C30 
scale, except items 29 and 30, is a reverse item (the worse the quality of life), it is clearly 
specified in the scoring rules that: for the functional domain and overall health status 
domain scores, the better the functional status and quality of life, and for the symptom 

  
 
27 
 
domain scores, the more symptoms or problems (the worse the quality of life). Therefore, it 
is also necessary to change the direction of calculating the standardization timescale of the 
functional domain. Specifically, calculate separately according to the following formula 
(where R is the full distance of scores in each field or item).  
Functional Area: SS = [1- (RS-1)/R] 100  
Symptom domain and global health status domain: SS = [(RS-1)/R] 100

9.Safety evaluation 
9.1 Adverse event observation 
AE refers to any adverse medical event that occurs in subjects or clinical subjects, and 
may not be causally related to treatment. Therefore, AE can be any bad or unintentional signs 
(such as: abnormal laboratory results), symptoms or transient drug-related diseases, and it 
should be considered whether it is related to medication. According to management needs, 
adverse events that occur before and after treatment are regarded as adverse events. Therefore, 
safety monitoring (reporting of adverse events or serious adverse events) should be carried 
out from the beginning of the subjects' enrollment to the end of the study. Therefore, adverse 
events that occurred during the signing of the informed consent form and the start of study 
treatment are also considered AEs. General adverse events: the outcome of the event can be 
closely followed or the corresponding symptomatic treatment can be carried out according to 
the experimental protocol. 
9.2 Assessment and management of adverse events 
1.AE classification 
Grade 1: mild; asymptomatic or mild: only clinical or diagnostic; no treatment is 
required. 
Grade 2: Moderate; requires minor, local or non-invasive treatment: age-appropriate 
instrumental limitation of activities of daily living. 
Grade 3: Severe or medically significant but not immediately life-threatening; cause 
hospitalization or prolong hospitalization; disabled; personal activities of daily living are 
restricted 
Level 4: Life-threatening; urgent treatment is required. 

  
 
30 
 
Grade 5: Death related to AE. 
2. AE record 
Record the name, severity, time of occurrence, duration, treatment measures and 
outcome of various AEs that occurred during the trial in detail, and fill in the case report form 
(CRF) truthfully. Abnormal laboratory test data is recorded on the CRF table, and the test is 
repeated at least once a week, and follow-up until the return to normal or the end of the study. 
3. Relevance to research intervention 
Irrelevant = There is no temporal relationship with hyperthermic perfusion chemotherapy, 
or there is a reasonable causal relationship between AE and another treatment method, 
concomitant disease or environment. 
Impossible = There is a temporal relationship with hyperthermic perfusion chemotherapy, 
but there is no reasonable causal relationship between AE and hyperthermic perfusion 
chemotherapy 
Maybe = there is a reasonable causal relationship between AE and hyperthermic 
perfusion chemotherapy. The lack of stopping hyperthermic perfusion chemotherapy or is not 
clear. 
It is possible that there is a reasonable causal relationship between AE and hyperthermic 
perfusion chemotherapy and drugs. Stopping hyperthermic perfusion chemotherapy has an 
effect on the response. 
It is clearly determined that there is a reasonable causal relationship between AE and 
hyperthermic perfusion chemotherapy. Stopping hyperthermic perfusion chemotherapy has an 
impact, and when it is clinically feasible, it will happen again if hyperthermic perfusion 
chemotherapy is repeated. 
9.3 Reporting and handling of serious adverse events 
1. Serious adverse events  

  
 
31 
 
SAE that occurs during the period from the end of the last chemotherapy to the end of 
the last chemotherapy for patients with serious adverse events refers to all adverse medical 
events that occur under any drug dose that are life threatening or cause death. "Serious" and 
"life-threatening" are defined as when the adverse event occurs, the subject is in danger of 
death; it is not assumed that more serious adverse events may lead to patient death. Usually 
include: the patient needs to be hospitalized or extended the current time; cause continuous 
and significant incapacity/disability; congenital malformations or birth defects and important 
medical events, some malpractices need to be treated in the emergency room; congenital 
malformations or Birth defects and important medical events, some malformations need to be 
treated in the emergency room; disability; congenital malformations or birth defects and 
important medical events, some malformations need to be treated in the emergency room. 
When important medical events occur, medical treatment and science are required to 
determine whether it is appropriate to report quickly, these important medical events may not 
immediately threaten life or cause death or require hospitalization, but may endanger the 
subject or may require intervention to prevent the occurrence of other results mentioned 
above. These should also generally be considered serious. 
2. Reporting procedures for serious adverse events 
The report of serious adverse events should start from the subject signing the informed 
consent and until 30 calendar days (including the 30th day) after the last use of the study drug. 
During the trial period, if a serious adverse event occurs, it must be reported to the clinical 
monitor and the main investigator within 24 hours, and the "Serious Adverse Event (SAE) 
Report Form for New Drug Clinical Research" shall be filled in, signed and dated, and faxed. 
The form should be immediately reported to the sponsoring unit, team leader unit, research 
unit ethics committee, China Food and Drug Administration (CFDA), and the food and drug 
administration of the region (province or city) where the investigator is located. 
During the continued drug supply period after the study, any serious adverse events must 
be reported to the sponsor within 24 hours. The information of all serious adverse events shall 
be recorded in the serious adverse event table. Serious adverse events that occur during the 
period of continued drug delivery to 30 days after the last dose must be reported. Serious 

  
 
32 
 
adverse events that occur 30 days after the last administration are generally not reported 
unless they are suspected to be related to the study drug. 
For serious adverse events, the symptoms, severity, time of occurrence, treatment time, 
measures taken, time and method of follow-up, and outcome should be recorded in detail. If 
the investigator believes that a serious adverse event is not related to the trial drug, but is 
potentially related to the study conditions (such as termination of the original treatment, or 
comorbidities during the trial), the relationship should be described on the serious adverse 
event page of the medical record report form Partially explained. If the intensity of an 
ongoing serious adverse event or its relationship with the test drug changes, the serious 
adverse event follow-up report should be sent to ethics immediately. All serious adverse 
events should be followed up until recovery or stability. 
10.Data management 
10.1 Filling out and handing over the case report form (CRF) 
The CRF is filled in by the investigator, and each selected case must complete the CRF. 
After being reviewed by the researcher and handed over to the data administrator for data 
entry and management. 
10.2 Data entry and modification 
Data entry and management are handled by dedicated personnel. In order to ensure the 
accuracy of the data, two data administrators should independently carry out double entry, 
after computer verification and manual verification, it is submitted to a statistician for blind 
verification and statistical analysis. 
For the questions in the case report form, the data manager creates a question and answer 
form (DRQ), and sends out inquiries to the investigator through the clinical monitor. The 
researcher should answer and return as soon as possible. The data manager will modify, 
confirm and enter the data according to the researcher's answer, and can issue a DRQ again if 
necessary. 

  
 
33 
 
10.3 Data lock 
After blindly reviewing and confirming that the established database is correct, the main 
researchers, applicants, and statistical analysts lock the data. The locked data files will no 
longer be changed, and the database will be handed over to statistical analysts for statistical 
analysis in accordance with the requirements of the statistical analysis plan. The problems 
found after the data is locked will be corrected in the statistical analysis program after 
confirmation. 
10.4 Data processing 
Statistical analysis is carried out by statistical analysis professionals according to the 
statistical analysis plan formulated in advance. The statistical analysis is carried out in 
accordance with the full analysis set determined by the principle of intentionality and the 
principle of compliance with the plan set. After the statistical analysis is completed, the 
statistical analysis staff will write a statistical analysis report, and the main researcher of this 
experiment will write a research report. 
11.Statistical analysis method 
11.1 General principles 
Unless otherwise specified, all statistical tests are two-sided tests, and P<0.05 can be 
considered as statistically significant differences. 
Quantitative data: use the number of cases, arithmetic mean, standard deviation, median 
and range description. Qualitative data: use frequency, composition ratio or percentage 
description. 
Statistical test: First consider using the parametric statistical method. If the data 
distribution differs greatly from the requirements of the test hypothesis, use the 
non-parametric statistical method. 
Statistical analysis: Use statistical software for statistical analysis.

11.2 Case characteristics 
Enrollment and completion status: Summarize the number of enrolled and completed 
cases in each center, and list the dropped cases. 
Baseline characteristics of general information: The baseline is defined as the data 
obtained during the case screening period. Describe the patient's demographic characteristics, 
symptoms and signs, comorbidities, allergies, medical history, etc. 
11.3 Safety evaluation 
The postoperative safety evaluation was completed during the first postoperative 
systemic chemotherapy. Evaluation of adverse reactions during HIIPEC is carried out at 
discharge. For the evaluation of adverse events/adverse reactions, comprehensively refer to 
the CTCAEv5.0 standard. Evaluation content includes: 
(1) Blood routine and liver and kidney function tests 
(2) Patient's response to HIIPEC 
(3) Adverse events 
12.Ethical requirements 
(1) The implementation of this trial protocol and trial research complies with the 
requirements of the "Declaration of Helsinki" and the "Quality Management Practice for Drug 
Clinical Trials" and other regulations. 
(2) Develop a trial plan before the start of a clinical trial, which is signed by the 
investigator for confirmation, and implemented after being approved by the ethics committee. 
If this protocol needs to be revised during the actual implementation of the clinical trial, it 
shall be submitted to the ethics committee for approval before implementation in written form. 
If important new data related to the puncture needle used in the experiment is found, the 
informed consent form must be revised in writing and sent to the ethics committee for 
approval, and the subject's consent will be obtained again. 

  
 
35 
 
(3) Before the start of the clinical trial, the researcher must provide the subject or his 
legal representative (guardian) with detailed information about the clinical trial, including the 
nature of the trial, the purpose of the trial, the possible benefits and risks, and other treatments 
available. methods and the rights and obligations of subjects in accordance with the 
"Declaration of Helsinki" shall enable subjects or their legal guardians to fully understand the 
clinical trial. The clinical trial can only be started after the subject or his legal guardian has 
given consent and signed the informed consent form. The subject’s informed consent form is 
in duplicate, one of which is given to the subject to keep and the other is kept in each test 
center. Each patient must leave a detailed contact address and telephone information. At the 
same time, the doctor should leave his contact number to the patient so that the patient can 
contact the researcher at any time when the patient's condition changes, which is also 
conducive to the researcher to understand the condition at any time. 
If an adverse reaction occurs during the experiment, the subject should be given active 
treatment to minimize the subject's suffering. 
If a serious adverse reaction causes permanent damage or even death to the patient, the 
researcher shall make appropriate financial compensation to the subject after it has been 
identified and approved by a specialized agency. 
13.Clinical trial quality control and quality assurance 
The quality control of this clinical trial is the responsibility of the researchers in each 
center, and the quality control of the data and analysis is the responsibility of the statistical 
analysts. During the research process, ensure that all the contents of the research plan are 
strictly observed and fill in the research materials correctly. 
(1) The trial protocol, CRF and informed consent shall be submitted to the clinical trial 
ethics committee of each participating unit for approval; 
(2) The researchers who participated in the trial carefully implemented the standard 
operating procedures of clinical trials before, during and after the trial; 

  
 
36 
 
(3) During the trial process, the clinical trial institutions of all participating units will 
monitor the correctness and completeness of the data in the CRF; 
(4) Participating researchers must undergo unified training, unified recording methods 
and judgment standards; 
(5) The entire clinical trial process should be conducted under strict screening; 
(6) Researchers should fill in the CRF according to the requirements, truthfully, in detail 
and carefully record the contents of the CRF to ensure that the CRF content is true and 
reliable; 
(7) The abnormal judgment standard of laboratory inspection shall be subject to the 
normal reference range of the inspection unit; 
(8) All observations and findings in clinical trials should be verified to ensure the 
reliability of the data and to ensure that the conclusions in the clinical trials are derived from 
the original data. There are corresponding data management measures in clinical trials and 
data processing stages; 
(9) Actively take measures against possible shedding to control the shedding rate of 
cases within 20%. 
14.Data preservation 
Researchers should keep all research data, including confirmation of all participating 
subjects (which can effectively check different records, such as CRF and original hospital 
records), all original signed patient informed consent forms, and all CRF records Detailed 
records, etc., and ensure the traceability of all laboratory inspections, are kept until 5 years 
after the end of the clinical study. 
15.Summary 
15.1 Acceptance criteria for case report forms 
After the CRF is completed by the investigator during the trial period, it shall be 
submitted to the principal investigator of the unit for review and signature. In accordance with 

  
 
37 
 
the requirements of the "Clinical Trial Record", the principal investigator of each research 
unit shall check the original medical records and CRF and review the following items: 
(1) The CRF must be checked with the original medical record. All the content recorded 
on the CRF should be recorded in the original medical record. 
(2) The name, mailing address, and telephone number of the subject on the medical 
record must be filled in, and their authenticity must be guaranteed. 
15.2 Preservation of case report forms 
The CRF is stored in eCRF; the informed consent is in duplicate, which is kept by the 
subject and the investigator. 
After all eCRFs were statistically processed, a clinical trial summary report is written 
and archived. The original medical record of the trial is kept by the medical record room of 
each hospital or the archives of the clinical trial institution. 
15.3 Summary of the case report form 
The researcher is responsible for establishing a clinical data database, collecting statistics 
on the data of each research unit and comprehensively collecting all the data. Each research 
unit writes a "Clinical Trial Subcenter Summary Table" and submits it to their respective 
testing unit after stamping. The statistical unit is responsible for completing the "Clinical Trial 
Summary Report", which is stamped and submitted to each participating unit. 
16. Responsibilities of all parties and regulations of paper publication 
16.1 Responsibility 
The clinical research sponsor must earnestly follow the corresponding provisions of the 
"Clinical Trial Quality Management Standards" and undertake its due responsibilities. 
16.2 Paper publishing regulations 
As research results, the relevant information obtained by this research is considered 
confidential. Until the main researcher completes and reviews the data analysis, the research 
results can be published and demonstrated with the authorization and consent of the main 
researcher, but the confidential or proprietary information cannot be disclosed.
