Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Advanced pelvic cancers are uncommon, with treatment being challenging. Around 4000 patients every year need treatment in the UK. Cancers can involve multiple organs and often need radiotherapy and chemotherapy before surgery. Surgery usually requires removal of multiple pelvic organs, including muscles, bone, and skin around the anus (the perineum). This can lead to complications relating to both the empty pelvis syndrome and closure of the perineal defect.
Reconstruction is challenging, with frequently occurring complications, reducing speed of recovery and quality of life. This study investigates complication frequency, quality of life and expenses following different reconstruction techniques. The investigators hope to improve patient and doctor decision-making in this area and find the best methods of reconstruction to improve outcomes.
REMACS has three work packages:
1. Maintenance of a database of patients undergoing colorectal surgery at Southampton and Salisbury Hospitals, including those undergoing extra-levator abdominoperineal excision and pelvic exenteration. This includes all routinely collected clinical data, imaging, health resource use, and patient reported outcome measures.
2. A collaborative national prospective cohort study investigating morbidity, health resource use, longitudinal quality of life outcomes (EORTC QLQ-C30 and disease-specific modules) and quality adjusted life years. The investigators will also assess financial toxicity using the comprehensive score for financial toxicity.
3. A qualitative study using semi-structured interviews to undertake a more complex evaluation of quality of life and patient experiences in patients that have recovered from their surgeries.
The last two work packages have now been funded by an NIHR Research for Patient Benefit Grant

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This is an observational multicentre retrospective and prospective cohort study, and a qualitative study. The project will have three working packages:
* Work package 1 - maintenance of a colorectal surgery database
* Work package 2 - prospective collaborative national UK study
* Work package 3 - qualitative analysis with semi-structured interviews
WORK PACKAGE 1 - COLORECTAL SURGERY DATABASE:
Data collected includes:
* Basic demographic information
* Co-morbidities at time of surgery
* Other cancer treatments
* Final cancer staging and diagnosis
* Type of procedure
* Methods of reconstruction
* Use of healthcare resource: (theatre time, surgical teams, use of consumables, index operation intensive care stay, total length of stay, planned or emergency readmissions, use of imaging for complications, re-interventions, and outpatient clinic use).
* Morbidity - empty pelvis syndrome complications with collation of all complications that occurred summarised into: (the highest Clavien-Dindo (CD) score, and the comprehensive complication index by accumulating CD graded complications that a patient has as a result of their surgery.
* Survival: overall and disease-free survival
* Patient reported outcome measures
Any other routinely collected clinical data will be included. Of particular mention we will include and analyse Cardiopulmonary exercise testing data, data derived from the perioperative medicine screening and assessment, data derived from prehabilitation, radiomic data e.g. muscle/fat structure and function derived from CT, MRI or PET-CT.
WORK PACKAGE 2 - PROSPECTIVE COLLABORATIVE STUDY:
Abdominoperineal excision and pelvic exenteration can be used in a wide range of cancer types, and in the case of pelvic exenteration can be used to manage both recurrent and primary cancers. The principal PROM used will be the EORTC QLQ-C30 with its modular questionnaires giving additional insight into disease-specific quality of life.
All amendments have been made in line with NIHR RfPB funding received in November 2024.
Patients will be recruited once a decision to undertake abdominoperineal excision or pelvic exenteration surgery has taken place. Participants will be sent a participant information sheet which will include the dates of when participants can expect follow up telephone calls, with information on how to contact the study team to change these should participants wish to. Once consented participants will undergo the following PROMs as part of their baseline questionnaire:
* EORTC QLQ-C30 with specific cancer-type modules
* EQ-5D-5L
* LRRC QoL
* Decision Regret
* Comprehensive Score for Financial Toxicity (COST), financial status questionnaire (non-validated) and Patient employment status questionnaires.
The investigators anticipate that participants will be able to self-assess the above PROMs on a paper printed form, however a member of the research team will be available to support the participant if required.
Clinical information will also be collected pre-operatively, including: demographic information, co-morbidities, cancer staging, and previous cancer treatments. Patients will be given copies of the follow up questionnaires at this time so participants have them as a reference when completing follow up questionnaires. Patients can opt for either email or telephone follow up for quality of life, if opting for email REDCap study will automatically send out emails based on the date of surgery.
The patient will then undergo their surgery with method of reconstruction at the discretion of the operating surgeon(s).
Following the index admission researchers will enter details on the hospital stay:
* Type of procedure
* Methods of reconstruction
* Theatre time
* Theatre teams
* Use of consumables
* Length of intensive care and hospital stay
* Use of imaging for complications
* Re-interventions for complications
* Discharge destination following index admission
* Final cancer staging and other pathological outcomes.
* Perineal and empty pelvis morbidity, and overall Clavien-Dindo and Comprehensive Complication Index
* NHS healthcare utilisation costs
* If applicable survival and cause of death
At 3 months post-operatively questionnaires will be repeated over the telephone including:
* EORTC QLQ-C30 with cancer-specific module
* EQ-5D-5L
* LRRC QoL
* Decision Regret
* Comprehensive Score for Financial Toxicity (COST), Patient reported heath resource utilisation and NHS healthcare utilisation costs.
At this same time point researchers will review routinely collected clinical data and use of in-hospital health resources to include:
* In-hospital health resource use: planned or emergency re-admissions, use of imaging to investigate complications, re-interventions (surgical and radiological), planned or unplanned outpatient visits.
* Longitudinal CCI scores updated, and if applicable an increase in CD if a more severe complication develops.
* If applicable cancer recurrence, survival and cause of death will be recorded.
Patients will be emailed or telephoned on the date specified on their participant information sheet, however if this time is not convenient then a better time will be arranged with the patient. If participants do not respond to the email or first telephone call then the investigators will make a further three separate attempts to contact the patient. If there is still no response participants will be deemed lost to the study.
This follow up process will be repeated again at 6 months and 12 months. At the 12 month time point the investigators will ask patients additional questions on their use of health care resources and their current financial status, to include:
* Use of community health resource use due to complications including: GP appointments and nursing home care days required for recovery from surgery.
* Use of healthcare resources at hospitals other than the treating hospital - clinic appointments and admissions
At the end of this time the patient will have completed the study.
WORK PACKAGE 3 - QUALITATIVE STUDY:
The qualitative study will recruit patients from work packages 1 and 2. The investigators will invite 30 purposefully sampled patients that are 3 months following their surgery. Suitable patients will be contacted with a posted participant information sheet and a telephone follow up call to allow participants to ask questions about the study. Following informed consent semi-structured interviews will take place with semi-structured open questions to guide the discussions.
Interviews will be recorded on an encrypted audiorecorder and then transcribed. The investigators will initially undertake three pilot interviews to review that the semi-structured interview schedule is adequate to fully explore our objectives and to obtain good quality interview transcripts for analysis. These pilot interviews once completed will be reviewed by the research team. The semi-structured interview schedule questions may be changed if the interviews are of poor quality, pilot interviews demonstrate new insights from participants that suggest fruitful lines of enquiry, or inconsistencies that require further exploration. If subsequent interviews are very different than the pilot interviews following these changes, then these early interviews will not be included in the qualitative analysis and additional patients will be recruited.
Patients recruited at 3-months following surgery will be offered a repeat interview at 12-months following their surgery
DATA ANALYSIS PLAN:
Statistical analysis:
The investigators will be collecting data on the timepoints as described above. Continuous data will be will be summarised using descriptive statistics (mean, median, standard deviation, lower and upper quartiles). Categorical data will be summarised using counts and percentages.
As studies are non-randomised, the investigators will utilise regression models and principal component analysis to adjust for confounding in this observational study.
In order to obtain our outcomes a brief summary of analyses is below.
Work package 1 (Colorectal Database):
Primary analysis:
\- Frequency of morbidity relating to the empty pelvis syndrome and perineal wound will be compared for different types of perineal reconstruction will be analysed using multiple linear regression.
Secondary analysis:
* Overall morbidity will be obtained using highest CD scores for different methods of perineal reconstruction analysed using multiple linear regression.
* Disease free and overall survival will be analysed using Kaplan-Meier curves and log rank tests with a multivariate Cox regression hazard model to identify factors independently associated with survival, including method of reconstruction.
Exploratory analysis:
* Other factors including age, gender, BMI, final staging, co-morbidities, type of operation, neoadjuvant chemoradiotherapy and use of intra-operative electron radiotherapy will be included in the analysis
* Other outcomes including primary operation time, lengths of stay, and readmissions will be explored
Work package 2 (prospective study):
Primary and secondary analysis:
* Patient reported outcome measures will be analysed using regression models, including linear mixed-effects models for repeat measures and adjusted analyses.
* The same clinical data fields will be collected as per work package 1, the analysis above repeated with exploratory analysis to find factors that are independently significantly associated with changes in the PROMs.
Health economic analysis:
Work package 1 (retrospective study):
The investigators will collect data on use of hospital healthcare resources in each patient group. The investigators will collect resource use for each parameter required for each patient. The investigators will then undertake costing using a micro-costing approach and health resource group costing for each parameter. Applying costs to each parameter will use a combination of manufacturer prices for consumables, National Cost Collection for the NHS, National Schedule of NHS Costs, NHS National Tariff and the Unit Costs of Health and Social Care from the Personal Social Services Research Unit. The investigators will then report overall costs associated with different methods of perineal reconstruction and the cost of complications that were encountered.
Work package 2 (prospective study):
The investigators will collect hospital healthcare resource use data prospectively and apply micro-costing to these parameters in the same way as per work package 1 for each patient and their method of reconstruction. The investigators will also ask patients to provide us with use of community healthcare resources as a result of their surgery, data for which the investigators will not be able to obtain from their clinical notes. Participants will receive EQ-5D-5L and EORTC QLQ-C30 questionnaires at baseline, 3 months, 6 months and 12 months. From these responses the investigators will map onto EQ-5D-3L in order to reduce the overall number of questionnaires patients are undertaking in our study. This will allow us to plot EQ-5D-3L responses for different methods of reconstruction and plot the area under the curve. Within the trial time a health economic model would be built which would follow the NICE reference case and ISPOR Task Force guidelines on health economic analysis. This will enable us to present Quality Adjusted Life Years and incremental cost-effective ratios for the different methods of perineal reconstruction.
Qualitative analysis:
Audio transcription will be transcribed verbatim, checked against the recording and anonymised. Data will be uploaded to NVivo for data management.
Preliminary summaries will be written after each interview to identify emerging themes to follow-up discussions. The follow-up interview will ask patients to reflect on the content of their previous interview and discuss any changes.
Longitudinal interview analyses will use constant comparative methods from grounded theory and data coded using NVivo's framework matrix facility to examine themes longitudinally, enabling comparisons within each case and across cases, focusing on changes over time. The stages of data analysis, drawing on longitudinal comparisons, will include:
1. Initial reading: Review interview data.
2. Preliminary coding: Two researchers code the data.
3. Team meeting: Discuss and refine codes with wider research/PPI team.
4. Individual Case Coding: Code all interview data for each participant.
5. Categorising Codes: Group codes into categories for each case.
6. Longitudinal comparisons: Within case and category comparisons focussing on changes over time.
7. Focused coding: Examine categories in relation to emerging concepts and phases.
8. Discussion on Themes: PPI co-led focus group discussions of final themes.
9. Development and Dissemination: Report write up are dissemination.
Based on an iterative process, emerging themes will be used to develop explanatory accounts. Analysis will draw on sociological perspectives of illness adaptation, recovery and self-management in addition to psychological theories of individual behaviour change.
All qualitative and quantitative data will inform 3 patient focus groups, where PPI and charity collaborators along with 5 newly trained PPI members will discuss data analyses from a patient perspective, contributing to initial discussions around developing a patient decision aid.
