Pelvic Exenteration Surgery

Summary of Program

Pelvic exenteration is a highly complex surgical procedure performed in selected patients presenting with locally advanced or recurrent pelvic malignancies. From 1994 to June 2022, 996 pelvic exenteration procedures have been performed at RPAH, which is the largest cohort of patients treated by a single institution worldwide. This has led to international recognition of RPAH being highly regarded for its novel multidisciplinary approach, expertise, innovation in surgical techniques, outstanding patient outcomes, and high quality scientific output.

The Pelvic Exenteration research program has developed two main databases that collect surgical outcomes (PESQI) and patient-reported outcomes (QOLPE) of all patients undergoing surgery at RPAH. Patients are followed from baseline (time before surgery) to 5 years postoperative with several measures, including quality of life outcomes. The program continues to evolve with 37 studies currently being conducted incorporating topics of surgical techniques, surgical outcomes, survival, decision-making, quality of life, nutrition, depression, anxiety, stress, physical activity, 3D printing and cost. In addition, the Pelvic Exenteration team was successful in receiving a competitive grant from the National Health and Medical Research Council. The team also published 19 peer-reviewed research manuscripts in national and international journals during this reporting period.

Highlights

  • From 1994 to June 2022, 996 pelvic exenteration surgeries were performed at RPAH, involving 916 unique patients. The 1000th pelvic exenteration is expected to be performed in July 2022. This is an amazing milestone for the program and will be the first single centre in the world to perform such an amount of pelvic exenterations. Data from these patients are entered into our surgical registry, which includes detailed patient characteristics and surgical outcomes.
  • Of the 996 pelvic exenteration surgeries performed at RPAH, 651 of these patients consented to participate in the long-running study titled ‘Quality of Life in patients following pelvic exenteration surgery’, since the beginning of this prospective cohort study in 2008. This study was initially funded by Cancer Australia and the Cancer Council Australia through the Priority-driven Collaborative Cancer Research Scheme. Currently, quality of life and other patient-reported outcomes are collected at 9 distinct time points from baseline (before surgery) to 5 years postoperatively.
  • The RPAH Pelvic Exenteration program is a member of the PelvEx Collaborative. PelvEx is an international collaborative group involving >140 units across the world with the aim to explore outcomes following pelvic exenteration. Recently, SOuRCe has completed an international benchmarking. This benchmark analysis has demonstrated that patients undergoing pelvic exenteration surgery at RPAH underwent more complex procedures including wider resections of bony pelvis, resulting in increased surgical times and postoperative recovery, but most importantly, achieved higher rates of clear resection margins (R0), lower 30-day mortality and superior survival outcomes. These results are a credit to the large group of multi-disciplinary staff involved in the delivery of the RPAH Pelvic Exenteration Surgical Program.

Peritonectomy Research Program

Summary of Program

Peritonectomy is a complex abdominal operation involving a combination of macroscopic tumour removal (cytoreductive surgery; CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) administered directly into the abdomen during surgery to kill any residual microscopic cancer cells following cytoreduction. This treatment approach has been shown to significantly increase survival, improve quality of life, and potentially offer a cure to patients with peritoneal metastases of colorectal or appendiceal origin, as well as metastatic gastric and ovarian cancer.

Due to increasing demand for this type of service, in October 2016 the NSW Government established a second state-wide Peritonectomy service at RPAH. This program has a foundation in patient monitoring and research, which includes interstate and international collaborations with other Peritonectomy centres. To ensure the continued pursuit of high quality, evidence-based practice, the patient data is centralised within a clinical and patient-reported outcomes (quality of life, work and health care utilisation) research database (PREMIER). This supports not only clinical auditing and reporting of data to the SLHD and NSW Ministry of Health (MoH), but also the ongoing development of research activity.

  • The Upper Gastrointestinal Research Program has recorded >1000 major cancer surgeries performed at RPAH since August 2017. The information from all these procedures are entered prospectively into the HUGO database, which include patient characteristics and extensive surgical outcomes. A number of research studies are nested within the HUGO Most recently the program started recruitment for the UNIQUE study (Upper Gastrointestinal Quality of life). This prospective cohort study aims to investigate quality of life outcomes following surgery for liver, biliary tract, pancreas, stomach and oesophageal disease. This long-term study will follow patients up to 5 years postoperatively.
  • The Very SuPPLe Trial is a randomised controlled trial that is investigating the effectiveness of preoperative very low calorie/energy diet two weeks prior to surgery on liver stiffness and size. This project received support from two external grants and is currently recruiting patients.
  • An artificial intelligence diagnosis study is underway, which looks to use deep learning to develop models that aid in diagnosis, and ultimately surgical decisions around hepatobiliary and pancreatic tumours. This study will be conducted in collaboration with the computational neuroimaging group at the Brain and Mind Centre, The University of Sydney.
  • The Fit-4-Home Trial was a randomised controlled trial that investigated the use of electronic devices in encouraging patients to move after surgery, reducing their hospital stay. This was a collaboration between RPAH and Chris O’Brien Lifehouse (COBLH). The results of the trial are now published in the ANZ Journal of Surgery.

Retroperitoneal Sarcoma Surgery

Summary of Program

Retroperitoneal sarcomas (RPS) comprise 15% of all soft tissue sarcomas (cancers arising in the connective tissue). They are malignant and can grow considerably large within the abdomen and pelvis. These may present late with obstructive symptoms and pain dependent on the organ or structure it abuts or invades. Management of patients with RPS is especially challenging when malignant and involves any vital organs or structures. The therapeutic strategies include surgical resection/removal, radiotherapy or chemotherapy, or a combination of the three. The dilemma is choosing an appropriate treatment or combination of treatments, and in which order the optimal treatment should be delivered to elicit the best response. A significant prognostic factor influencing survival is local recurrence. Hence, this and other factors such as tumour grade, size and staging need to be taken into account when deciding the optimal advent treatment for patients with RPS. In November 2020, the Retroperitoneal Sarcoma Research Program was established across RPAH and COBLH, with the overarching aim of establishing and maintaining an ongoing and comprehensive clinical and outcomes database (SPARC), nested into multiple research projects.

Highlights

  • In October 2020, RPAH has commenced collaborating research with international institutions such as Transatlantic Australasian Retroperitoneal Sarcoma Working Group (TARPSWG). The main aim of this collaboration is to evaluate current outcomes and evidence in the management of patients with primary, locally recurrent, and metastatic retroperitoneal sarcoma. Currently, RPAH and COBLH are involved in the RESAR study, which includes prospective collection of primary retroperitoneal sarcoma patient’s data, radiological and pathological material.
  • From November 2020, the Retroperitoneal Research Program started the development of the Sarcoma of the Pelvis, Abdomen or Retroperitoneum Collaboration (SPARC) database for RPAH and COBLH. After receiving ethics approval in February 2021, prospective data collection commenced for all patients diagnosed with retroperitoneal sarcoma, and discussed at RPAH and COBLH multidisciplinary team meeting. The SPARC database now includes data for 144 patients. The data collected in the SPARC database includes extensive patient information, pathology, medical oncology, surgical and patient-reported outcomes, including quality of life.
  • In mid-2021, a collaboration was established between RPAH, COBLH, the ProCan facility at Children’s Medical Research Institute, Westmead Hospital and The University of Sydney, to conduct the study titled ‘Proteomics in retroperitoneal intra-abdomino-pelvic extremity soft tissue sarcomas’. This study aims to identify a proteomic signature of relapse in patients with localised leiomyosarcoma at diagnosis. Recruitment is currently underway.

Preoperative Optimisation

Summary of Program

Preoperative optimisation is the process of enhancing general health before surgery. This concept encompasses many components of care including medical, physical exercise, nutritional support and psychological support. There are multiple projects being undertaken within this research program at SOuRCe, including the areas of mental health, nutrition and exercise.

Recently, two PhD programs were completed:

 Dr Kate McBrideSurgical outcomes for patients with serious mental illness.

Mental health can greatly affect the recovery period following surgery, and those who suffer from a serious mental illness would likely be at a higher risk of a poorer outcome. This thesis found that those suffering from a serious mental illness experienced a range of considerable physical, social and occupational challenges, that affected their outcomes following surgery. These patients had greater surgical morbidity including higher postoperative complications, longer lengths of hospital stay, greater hospital readmissions, and higher costs. The evidence generated within this thesis demonstrated there is a considerable need to improve the delivery of surgical care to this vulnerable patient group.

Dr Sophie HoganExpanding the evidence base for perioperative nutrition management in pelvic exenteration surgery.

Patients undergoing a pelvic exenteration surgery will often have significant compromise to their colorectal system, requiring a closely monitored nutritional regime after the procedure. This thesis sought to investigate if nutrition assessment tools and/or methodologies predict outcomes after this surgery, determine beneficial perioperative nutrition support therapies. It was found that patients who were malnourished before surgery had significantly increased length of postoperative stay, surgical procedure times, intensive care unit readmissions, and decreased quality of life. Through this thesis, evidence on more effective preoperative nutrition assessments was generated.

SOuRCe was able to obtain a large NHMRC grant to develop the PRIORITY Trial. The PRIORITY Trial is a multi-centre randomised controlled trial investigating the effectiveness of a preoperative exercise and education program on patients undergoing surgery for advanced primary or recurrent gastrointestinal cancers compared to usual care. The clinical trial is being conducted at RPAH and COBLH in Sydney and Peter MacCallum Cancer Centre (PMCC), in Melbourne. The PRIORITY Trial commenced patient recruitment in November 2021.

Surgical Patient Flow

All patients scheduled for Pelvic Exenteration, Cytoreductive Surgery (CRS), and Upper Gastrointestinal surgery (including Oesophagectomy, Hepatectomy, Gastrectomy, or Pancreatectomy) are eligible to participate.

Surgical Volume

The target recruitment for the PRIORITY Trial is 172 participants. Participant recruitment is expected to be completed by June 2024. Due to COVID-19 restrictions a contingency plan was established in October 2021, prior to the first participant being recruited. These changes were made to allow patients to participate in the trial via telehealth. To date, a total of 38 participants have been recruited into the trial (28 participants from RPAH/COBLH and 10 participants from PMCC).

Highlights

  • The PRIORITY Trial received ethical approval with the Human Research Ethics Committee at Concord Repatriation General Hospital in March 2020 and governance authorisation in May 2021. A research officer, Ms Jenna Bartyn, was appointed in December 2020 to assist in the coordination of the trial. The trial was prospectively registered within the Australian New Zealand Clinical Trial Registry (ANZCTR) in May 2021 (ACTRN12621000617864), with a detailed protocol published in BMC Cancer in April 2022. The first participant was recruited in November 2021.

During the last 3 years, a number of studies have also been established:

  • Preoperative technology-driven multimodal intervention for patients undergoing cancer surgery (app study): The study is looking at the barriers, facilitators and adoption of a preoperative program by surveying cancer patients undergoing surgery, their carers and treating clinicians. The study received ethical and governance approval and commenced recruitment in 2021. A total of 12 cancer patients and 7 clinicians have been recruited to date.
  • Research priorities in prehabilitation for patients undergoing cancer surgery (international Delphi study): The investigators are conducting a Delphi study with international multidisciplinary experts to identify key research priorities in prehabilitation for patients undergoing cancer surgery. Almost 200 international prehabilitation experts have currently completed the first round survey.
  • Mechanistic understanding of how preoperative exercise improves outcomes: A substudy of the NHMRC-funded PRIORITY randomised controlled trial (biomarker study): This project received funding from the Australian and New Zealand College of Anaesthetists Foundation. The study received ethics approval in November 2021 and governance approval in March 2022. All patients recruited into PRIORITY are invited to participate in this study. Currently 12 participants have been recruited.
  • Safety, feasibility and validity of remote physical assessments during the covid-19 pandemic (validation/reliability study): The study is being conducted at RPAH and Neuroscience Research Australia (NeuRA) and is investigating the validity and reliability of conducting online physical assessments in patients presenting with cancer and older people. The study received ethics and governance approval in June 2022 and will commence participant recruitment in July 2022.
  • Comparative efficacy of preoperative interventions to improve postoperative outcomes in cancer patients (network meta-analysis): This network meta-analysis is being conducted at RPAH and is looking at the comparative effectiveness of preoperative interventions in cancer patients on postoperative complications and length of hospital stay. The study is currently in the data analysis phase.
  • The role of physical, nutritional and/or psychological statuses on surgical outcomes, patients outcomes and survival following major cancer surgery: This retrospective cohort study is looking at patients who had undergone cytoreductive surgery or pelvic exenteration surgery for locally advanced or recurrent pelvic cancers. The paper is currently under review at Annals of Surgical Oncology. 
  • Reference values for the Six Minute Walking test in cancer patients: This international multicentre study, involves individual patient data form RPAH, PMCC and from another 24 sites in Canada, New Zealand and the UK. The main aim of this study is to provide reference values of the Six Minute Walking Test for cancer patients undergoing gastrointestinal surgery.

Highlights

  • The Vascular Surgery Research Program collects information of all vascular surgery undertaken at RPAH into the Vascular Surgery (VaS) database. From January 2020, 878 patients were entered into the database. The main aim of this database is to provide data for internal monitoring, improvement activities and assist the development of vascular surgery research projects.
  • Currently, The Vascular Surgery Research Program has 14 active research projects at RPAH. Some of these studies include:
    • Vascular endothelial growth factor levels in type 2 endoleak requiring intervention: This study aims to investigate vascular endothelial growth factor and Interleukin-6 levels in patients with previous endovascular abdominal aortic aneurysms repair who have a type 2 endoleak that requires treatment due to ongoing sac enlargement, in order to assess whether the excluded abdominal aortic aneurysms sac is a source of vascular endothelial growth factor and Interleukin-6 that may potentially explain the behaviour of type 2 endoleak. This study is finalising patient recruitment at the end of 2022.
    • Changing management and outcomes of ruptured abdominal aortic aneurysm (rAAA): A comparison of endovascular vs open technique: This retrospective study aims to investigate the change in proportion of endovascular rAAA repair between 2010 and 2020 at RPAH and compare this to NSW and Australian/New Zealand data. This study data is currently being analysed.
    • Abdominal aortic aneurysm (AAA) explants in Australia: This study aims to describe the epidemiology, clinical outcomes, and changing management trends of explantation after AAA repair in Australia and correlate potential risk factors with patient outcomes. The manuscript for this study is currently being drafted.

Robotic Surgery

Summary of Program

The surgical robotics program at RPAH is one of the most comprehensive multi-specialty public programs in Australia. It is truly unique in that it is governed by a comprehensive research framework whereby every patient undergoing robotic-assisted surgery (RAS) is enrolled in a research study. The use of RAS on the campus is also strongly embedded in ongoing education and training.

Currently there are five surgical specialties utilising the Intuitive Devices da Vinci Xi Surgical System at RPAH including benign gynaecology, cardiothoracic, colorectal, upper gastrointestinal and urology. In addition, the Stryker MAKO Robotic System is being used by orthopaedics in the Institute of Rheumatology and Orthopaedics (IRO) at RPAH. Clinical and patient-reported data on all robotic cases performed within the district is centralised in an overarching research database (BEST).

Orthopaedic Surgery

Summary of Program

The Orthopaedic Surgical Research Program was established to enhance academic, clinical surgical excellence and patient needs in musculoskeletal injuries and other conditions, to improve patient outcomes. There are five distinct research areas within the program: (i) robotics, (ii) lower limb arthroplasty, (iii) sarcoma, (iv) upper limb, and (v) foot & ankle. Committed to an evidence-based approach to patient education and appropriate care, the Orthopaedic Surgical Research Program strives to further the field through high quality research in each of these areas.

Since the program began in 2017, a comprehensive database (LOAD) has been established to capture every elective lower limb joint replacement performed at the Institute of Rheumatology and Orthopaedics (IRO) at RPAH, now containing over 3,500 patients. With the purchase of the Stryker MAKO Robotic System, the program has pursued research in the robotic arthroplasty space including the collection of patients reported outcomes from every patient undergoing robotic knee or hip arthroplasty (PRO-LOAD). More recently, the program has built a focus around patient education and surgical decision-making, for example through the development of patient decision aids.

Highlights

  • Clinically relevant data for all hip and knee replacements performed at RPAH are captured in the Lower Limb Arthroplasty Database (LOAD). Since 2017 this database has now captured over 3,500 cases. Of these, 373 were performed within the 2021/2022 financial year, 159 being hip replacements and 214 being knee replacements.
  • The department has been supporting researched innovation in the area of arthroplasty through the purchase of the MAKO (Stryker) robot and recording of patient-reported outcomes which has been closely monitored by a Data Safety and Monitoring Board. The department has performed over 400 surgeries with this device, with 54 being performed in the 2021/2022 financial year.
  • In 2019 the orthopaedic department was awarded a grant of over $250,000 to support a higher degree research project investigating how to best support the decision-making process of patients considering knee replacement for end-stage osteoarthritis. The goal of this project is to design a decision aid for these patients.
  • The department is also supporting another higher degree research project investigating the role of dual mobility total hip replacement in the management of femoral neck fractures in older patients. The goal of this project is to evaluate if the use of dual mobility cups reduce the risk of adverse events, especially dislocation.
  • In 2022 the orthopaedic department commenced recruitment for the RASKAL Trial, a national registry-nested, multicentre randomised trial assessing clinical, intraoperative, functional, radiographic and survivorship outcomes, the first trial of its kind seeking to produce a high quality comparison between robotic assisted and computer navigated surgical approaches.

Cancer Variation

Summary of Program

This program of work aims to identify variations in optimal care for patients diagnosed with cancer who require a surgical procedure. Through the application of high quality research methodologies, the program pursues the development of interventions to increase adherence to best practice guidelines. Crossing a range of surgical disciplines, including head and neck and colorectal cancer surgery, collaborations with local and international are fostered. These activities allow SOuRCe to partner with a broad spectrum of institutions and organisations.

  • Hide and seek project with the Cancer Council NSW: Since 2018, SOuRCe and RPAH have been involved Hide and Seek with Hereditary Cancer project led by the Cancer Council NSW. The project aims to utilise implementation science methods to ensure risk-appropriate completion of the tumour testing and referral pathway for patient with colorectal cancer at risk of Lynch syndrome. All seven phases of the project have been completed. The final results of this project are expected to be published at the end of 2022.
  • Cross-cultural adaptation and validation of the CCCQ-P: The outcomes of the translation and cross-cultural adaptation of the Cancer Care Coordination Questionnaire for Patients (CCCQ-P) into Arabic and Chinese languages has been completed and is currently available in the journal Patient Preference and Adherence. Further validation and psychometric testing of the instrument is expected to occur in the coming years.
  • Head and neck cancer pathways: This program of work has been running since 2017, and aims to investigate variations in pathways to diagnosis and treatment of head and neck cancer in NSW. This program is run in collaboration with clinicians at the Chris O’Brien Lifehouse, the Mid North Coast Cancer Institute, and the Northern NSW Cancer Institute.
