Consensus statement on the multidisciplinary management of patients with recurrent and primary rectal cancer beyond total mesorectal excision planes.

The management of primary rectal cancer beyond total mesorectal excision planes (PRC‐bTME) and recurrent rectal cancer (RRC) is challenging. There is global variation in standards and no guidelines exist. To achieve cure most patients require extended, multivisceral, exenterative surgery, beyond conventional total mesorectal excision planes. The aim of the Beyond TME Group was to achieve consensus on the definitions and principles of management, and to identify areas of research priority.

Surgery for recurrent rectal cancer: higher and wider?

Aim  There has been a steady increase in the number of centres that carry out resection of locally recurrent rectal cancer (LRRC). The aim of this review was to highlight the present management and suggest technical strategies that may improve survival and quality of life.

The Outcomes and Patterns of Treatment Failure After Surgery for Locally Recurrent Rectal Cancer

Objective: To assess the outcomes and patterns of treatment failure of patients who underwent pelvic exenteration surgery for recurrent rectal cancer. Background: Despite advances in the management of rectal cancer, local recurrence still occurs. For appropriately selected patients, pelvic exenteration surgery can achieve long-term disease control. Methods: Prospectively maintained databases of 5 high volume institutions for pelvic exenteration surgery were reviewed and data combined. We assessed the combined endpoints of overall 5-year survival, cancer-specific 5-year mortality, local recurrence, and the development of metastatic disease. Results: Five hundred thirty-three patients who had undergone surgery for locally recurrent rectal cancer were identified. Five-year cancer-specific survival for patients with a complete (R0) resection is 44%, which was achieved in 59% of patients. For those with R1 and R2 resections, the 5-year survival was 26% and 10%, respectively. Radical resection required sacrectomy in 170 patients (32%), and total cystectomy in 105 patients (20%). Treatment failure included local recurrence alone in 75 patients (14%) and systemic metastases with or without local recurrence in 226 patients (42%). Chemoradiotherapy before exenteration was associated with a significant (P < 0.05) improvement in overall 5-year cancer-specific survival for those patients with an R0 resection. Postoperative chemotherapy did not alter outcomes. Conclusions: R0 resection of the pelvic recurrence is the most significant factor affecting overall and disease-free survival. The surgery is complex and often highly morbid, and where possible patients should be given perioperative chemoradiotherapy. Further investigations are required to determine the role of adjuvant chemotherapy.

Surgical resection of recurrent colonic cancer

Locoregional recurrence of colonic cancer includes anastomotic recurrence, associated nodal masses, masses that involve the abdominal wall and pelvic masses. The aim of this study was to report the outcome of resection of such recurrences and to provide guidance on the management of this disease.

Systematic review of health-related quality of life issues in locally recurrent rectal cancer

The standardization of surgical techniques supplemented with appropriate neoadjuvant chemoradiation has led to the decline in local recurrence rates of rectal cancer (LRRC) from 25–50% to 5–10%. The outcomes reported for surgical intervention in LRRC is encouraging, however, a number of controversies exist especially in the ultra‐advanced and palliative setting. Incorporating health‐related quality of life (HRQoL) outcomes in this field could supplement traditional clinical endpoints in assessing the effectiveness of surgical intervention in this cohort. This review aimed to identify the HRQOL themes that might be relevant to patients with LRRC. A systematic review was undertaken to identify all studies reporting HRQoL in LRRC. Each study was evaluated with regards to its design and statistical methodology. A meta‐synthesis of qualitative and quantitative studies was undertaken to identify relevant HRQoL themes. A total of 14 studies were identified, with 501 patients, with 80% of patients undergoing surgery. HRQoL was the primary endpoint in eight studies. Eight themes were identified: physical, psychological and social impact, symptoms, financial and occupational impact, relationships with others, communication with healthcare professionals and sexual function. The impact on HRQoL is multifactorial and wide ranging, with a number of issues identified that are not included in current measures. These issues must be incorporated into the assessment of HRQoL in LRRC through the development of a validated, disease‐specific tool. J. Surg. Oncol. 2015 111:431–438.

Current UK management of locally recurrent rectal cancer.

Aim  The study aimed to determine current UK practice in the management of locally recurrent rectal cancer (LRRC).

Systematic review of health-related quality of life in patients undergoing pelvic exenteration

BACKGROUND Pelvic exenteration is a radical operative treatment reserved for the management of a number of advanced primary and recurrent pelvic malignancies, including, rectal, gynaecological and urological. The advances in radiological staging, surgical techniques and greater use of chemotherapeutic agents haves translated clinically into improvements in the overall survival of this cohort of patients, irrespective of underlying disease pathology. Consequently, a greater proportion of the surviving population will present to healthcare professionals with a range of physical and psychological issues, therefore the profiling and understanding of the health-related quality of life (HrQoL) is integral to the long term management of this cohort of patients. The aim of this systematic review is to identify HrQoL themes from the current literature relevant to patients undergoing a pelvic exenteration. METHODS Literature searches were performed in three databases: MEDLINE (1975-November 2015), EMBASE and CINAHL. Each study was evaluated with regards to its design and statistical methodology. Data quality was reviewed in accordance with the Newcastle-Ottowa score and Critical Appraisal Skills Programme Checklist (CAPS) for quantitative and qualitative data accordingly. A narrative synthesis of all identified HrQoL issues was undertaken using the principles of content analysis. RESULTS A total of 24 studies were identified; 20 quantitative and 4 qualitative with 976 patients assessed in total. HrQoL was assessed as the main primary endpoint in 15 studies. The majority of studies were retrospective. Baseline data prior to the initiation of treatments were available in 6 studies alone. Nine themes were identified across the literature, which included body image, social impact, sexual function, treatment expectations, symptoms, communication, psychological impact, relationships and work and finance. CONCLUSIONS Pelvic exenteration has a wide ranging impact on patients HrQoL affecting a range of physical and psychological domains.

Systematic review of emergency laparoscopic colorectal resection

Laparoscopic surgery (LS) has become standard practice for a range of elective general surgical operations. Its role in emergency general surgery is gaining momentum. This study aimed to assess the outcomes of LS compared with open surgery (OS) for colorectal resections in the emergency setting.

The effect of trainee research collaboratives in the UK

Trainee-led networks have pioneered a novel collaborative approach to research in the UK. Established at a similar time to the UK National Institute for Health Research in 2006, collaborative groups have developed new pathways for doctors in full-time specialty training to design, disseminate, and deliver high-quality, multicentre research. In parallel, the National Institute for Health Research set up Clinical Research Networks (CRNs) to coordinate delivery of research across 30 clinical specialties and 15 English regional networks. Analogous networks have also been established by the devolved administrations in Scotland, Northen Ireland, and Wales. CRNs provide infrastructure to promote and coordinate research, including funding research support staff and providing research skills training. Using gastrointestinal surgery as an example, we sought to quantify trainee-led collaborative research network engagement and compare hospital participation with CRN studies. We only considered CRN and trainee-led collaborative studies involving ten or more hospitals with information available about participating sites. We searched the CRN portfolio for closed gastrointestinal and general surgery studies. We contacted trainee networks via a national mailing list to identify trainee studies. We derived denominators from the total number of hospitals offering emergency or major elective gastrointestinal surgery. Overall, 238 (99%) of 241 UK hospitals providing general surgery services participated in one or more trainee-led collaborative studies over the past decade compared with 191 (79%) of 241 for CRN studies. With the three trainee-led studies that had been adopted into the CRN portfolio excluded, participation in trainee-led research remained similar, at 236 (98%) of 241. Trainee groups delivered 15 studies overall: 12 observational studies and three randomised controlled trials (RCTs), coordinated by five regional and two national trainee networks (appendix). These numbers compared with three observational studies and eight RCTs coordinated by the CRN. We noted strong participation in trainee collaborative studies, even in regions with low CRN coverage, with the mean number of studies per hospital greater for collaboratives than for CRNs (appendix). Regions with a Royal College of Surgeons Surgical Trials Centre had greater participation in both trainee and CRN studies: the mean number of studies per hospital was 8·2 versus 6·0 in regions without. Trainee-led collaboratives have driven substantial additional research participation across the UK, on top of that achievable through CRNs alone, and have engaged additional gastrointestinal surgery units with little infrastructure or associated costs. This success is now being replicated in other specialties, with the British Neurosurgical Trainee Research Collaborative engaging 26 of 30 UK adult trauma-receiving neurosurgical units in the RESCUE-ASDH RCT. As the collaborative model is extended globally, it offers a powerful opportunity to promote a collaborative research culture and grow capacity with minimal investment. Synergy between trainee-led networks and CRNs could maximise delivery of high-quality research across the UK.

Partial anterior sacrectomy with nerve preservation to treat locally advanced rectal cancer

Most studies that have reported outcomes after composite abdomino‐sacral resection for locally advanced/recurrent rectal cancer have involved resections below the S2/3 disc space. Involvement of the sacrum above this level is uncommon and, until recently, was considered a contraindication to resection.
