Acceptability and Feasibility of an Isometric Resistance Exercise Program for Abdominal Cancer Surgery: An Embedded Qualitative Study.

Although it is recognized in the early stages of cancer recovery that changes in lifestyle including increases in physical activity improves physical function, there are no clear findings whether low versus moderate intensity activity or home or gym exercise offer optimal benefit. Isometric-resistance exercises can be carried out with very little equipment and space and can be performed while patients are bed-bound in hospital or at home. This embedded qualitative study, based in an English hospital trust providing specialist cancer care, was undertaken as a component of a feasibility trial to evaluate the acceptability and feasibility of an isometric-resistance exercise program and explore the suitability of functional assessments by drawing from the experiences of abdominal cancer patients following surgery. Telephone interviews were undertaken with 7 participants in the intervention group, and 8 interviews with the usual care group (n = 15). The gender composition consisted of 11 females and 4 males. Participants' ages ranged from 27 to 84 (M = 60.07, SD = 15.40). Interviews were conducted between August 2017 and May 2018, with audio files digitally recorded and data coded using thematic framework analysis. Our results show that blinding to intervention or usual care was a challenge, participants felt the intervention was safe and suitable aided by the assistance of a research nurse, yet, found the self-completion questionnaire tools hard to complete. Our study provides an insight of trial processes, participants' adherence and completion of exercise interventions, and informs the design and conduct of larger RCTs based on the experiences of abdominal cancer surgery patients.

An allied health rehabilitation program for patients following surgery for abdomino-pelvic cancer: a feasibility and pilot clinical study.

PURPOSE: To investigate the feasibility of conducting a rehabilitation program for patients following surgery for abdomino-pelvic cancer. METHODS: A non-randomised controlled before-and-after study. Patients who had undergone surgery for stage I-III abdomino-pelvic cancer (colorectal, gynaecological or prostate cancer) were recruited. The rehabilitation group (n = 84) received an 8-week, bi-weekly education and exercise program conducted by a physiotherapist, exercise physiologist, health psychologist and dietician, supplemented by exercise diaries and telephone coaching sessions. The comparator group (n = 104) completed postal questionnaires only. Feasibility measures, functional exercise capacity, muscle strength, physical activity levels, pelvic floor symptoms, anxiety and depression, health-related quality of life (HRQoL) and self-efficacy were measured at baseline (time 1), immediately post-intervention (time 2) and at 6 months post-baseline (time 3) and compared within- and between-groups. RESULTS: The consent rate to the rehabilitation program was 24%. Eighty-one percent of the rehabilitation group attended 85-100% of 16 scheduled sessions. Overall satisfaction with the program was 96%. Functional exercise capacity, handgrip strength in males, bowel symptoms, physical activity levels, depression and HRQoL were significantly improved in the rehabilitation group (p < 0.05) at time 2. The improvements in all these outcomes were sustained at time 3. The rehabilitation group had significantly improved physical activity levels, depression and HRQoL compared with the comparator group at times 2 and 3 (p < 0.05). CONCLUSION: Recruitment to this oncology rehabilitation program was more difficult than expected; however, attendance and patient satisfaction were high. This program had positive effects on several important clinical outcomes in patients following abdomino-pelvic cancer treatment. TRIAL REGISTRATION: ANZCTR 12614000580673.

Early mobilization programme improves functional capacity after major abdominal cancer surgery: a randomized controlled trial.

Background: Major abdominal oncology surgery is associated with substantial postoperative loss of functional capacity, and exercise may be an effective intervention to improve outcomes. The aim of this study was to assess efficacy, feasibility and safety of a supervised postoperative exercise programme. Methods: We performed a single-blind, parallel-arm, randomized trial in patients who underwent major abdominal oncology surgery in a tertiary university hospital. Patients were randomized to an early mobilization postoperative programme based on supervised aerobic exercise, resistance and flexibility training or to standard rehabilitation care. The primary outcome was inability to walk without human assistance at postoperative day 5 or hospital discharge. Results: A total of 108 patients were enrolled, 54 into the early mobilization programme group and 54 into the standard rehabilitation care group. The incidence of the primary outcome was nine (16.7%) and 21 (38.9%), respectively (P=0.01), with an absolute risk reduction of 22.2% [95% confidence interval (CI) 5.9-38.6] and a number needed to treat of 5 (95% CI 3-17). All patients in the intervention group were able to follow at least partially the exercise programme, although the performance among them was rather heterogeneous. There were no differences between groups regarding clinical outcomes or complications related to the exercises. Conclusions: An early postoperative mobilization programme based on supervised exercises seems to be safe and feasible and improves functional capacity in patients undergoing major elective abdominal oncology surgery. However, its impact on clinical outcomes is still unclear. Clinical trial registration: NCT01693172.

Objectively measured mobilisation is enhanced by a new behaviour support tool in patients undergoing abdominal cancer surgery.

INTRODUCTION: Mobilisation reduces the risk of complications after abdominal surgery. Despite that, patients spend most of their time immobilised during hospital stay. Hence, the aim of this study was to evaluate a tool called the Activity board, which includes behaviour change techniques, regarding effects on mobilisation and postoperative recovery after abdominal cancer surgery. MATERIAL AND METHODS: Patients who were planned for abdominal surgery due to colorectal, ovarian or urinary bladder cancer, and at least three postoperative days at Karolinska University Hospital were included in this non-randomised controlled trial, from January 2017 to May 2018. The patients were allocated to Activity board or standard treatment when they were admitted to hospital. Mobilisation was evaluated objectively with activity monitor the first three postoperative days, and postoperative recovery was assessed continuously during hospital stay. RESULTS: In total, 133 patients, mean (sd) age 68.1 (12.3) years were included. The patients with the Activity board had postoperatively higher levels of mobilisation, compared to standard treatment, as mean value over the first three days, steps, median (min-max) 1057 (3-10433) and 360 (0-6546), respectively (p = 0.001), and for each day separately. Further, the group with the Activity board had a shorter length of stay, 6 (3-13), compared to standard treatment 7 (3-14) (p = 0.027). CONCLUSION: The Activity board is an effective tool to enhance mobilisation after abdominal surgery due to cancer, in hospital settings. Using the Activity board could lead to improved postoperative recovery.

[Special situations of preconditioning and prehabilitation in oncological visceral surgery]. / Spezialsituationen der Präkonditionierung und Prähabilitation in der onkologischen Viszeralchirurgie.

BACKGROUND: Prehabilitation prior to complex visceral oncological surgery is playing an increasingly important role. OBJECTIVE: The aim of this review article is to present special situations of preconditioning in visceral oncological patient cohorts. The following conditions were defined as special situations with subsequently increased risk profile: cardiopulmonary comorbidities, geriatric patients, neoadjuvant therapy and simultaneous fatigue. MATERIAL AND METHODS: A selective literature review based on a search in the electronic databases MEDLINE, PubMed, Cochrane Library and the International Standard Randomization Controlled Trial Number (ISRCTN) was performed. RESULTS: The identification of high-risk patients is an essential part of the preoperative evaluation conducted by the anesthesiologist prior to surgery. The cardiovascular and the pulmonary risk profile are determined by means of prediction indices evaluating patient-specific and surgery-related risk factors. The increased use of new oral anticoagulants and dual platelet aggregation inhibition requires individualized treatment strategies. Numerous studies have shown clinically relevant effects of exercise therapy interventions throughout all phases of oncological treatment. In addition to positive effects on therapy-associated side effects, sport can also counteract the effects of sedentary behavior in cancer patients and improve the health-related quality of life. The effectiveness of sport and exercise therapies as well as psychological interventions in oncological patients with fatigue (CRF) is broad, with important components being motivation and compliance. DISCUSSION: In high-risk patients an interdisciplinary approach to planning and conduction of prehabilitation is essential for the early detection and optimization of perioperative risk factors and potential complications. The aim is faster recovery, reduced morbidity and mortality and the possibility to improve long-term survival and quality of life.

A systematic review of prehabilitation programs in abdominal cancer surgery.

INTRODUCTION: Prehabilitation programs aim to optimise patients in order to enhance post-operative recovery. This study aims to review the composition of prehabilitation programs for patients undergoing major abdominal cancer surgery and define the outcome measures that are used to evaluate this intervention. METHODS: A systematic literature review of all comparative studies on prehabilitation versus standard care in patients undergoing abdominal cancer surgery was performed in accordance with PRISMA guidelines. Literature search was performed using Medline, OVID, EMBASE, Google Scholar, and Cochrane databases. Outcomes of interest included prehabilitation program composition (exercise, nutritional, and psychological interventions), duration, mode of delivery, and outcome measures used to determine impact of prehabilitation versus standard care. RESULTS: 9 studies (7 randomised controlled and 2 prospective non-randomised trials) comprising of 549 patients (281 prehabilitation versus 268 standard care) were included in this review. 5 studies reported patients undergoing surgery for colorectal cancer, 2 for bladder tumours, 1 for liver resections, and 1 involving unspecified abdominal oncological operations. The 6 min walk test (6MWT) was used in 4 studies to measure functional capacity with a threshold of >20 m improvement at 4-8 weeks post-operatively deemed significant (distance range from 278 to 560 m). Changes in anaerobic threshold and VO2max with prehabilitation were evaluated in 5 studies (ml/kg/min). Health-related quality of life was evaluated using SF-36 system, anxiety assessed using hospital anxiety and depression score (HADS). Post-operative complications were classified according to the Clavien-Dindo classification with no significant difference between prehabilitation and standard care groups. CONCLUSION: Prehabilitation programs in patients undergoing abdominal cancer surgery remain heterogeneous in their composition, mode of administration, outcome measures of functional capacity that are used to evaluate their impact. All these aspects require standardisation prior to the evaluation of prehabilitation on a larger scale.

[Malignant tumors of the abdominal wall. 10 years of experience at the Saint-Louis Hospital]. / Tumeurs malignes de la paroi abdominale. Dix ans d'expérience à l'Hôpital Saint-Louis.

The authors present a 10-year retrospective study of 52 patients with dermatofibrosarcomas (33 cases), sarcomas (13 cases) and desmoid tumours (6 cases) operated in their department. All these tumours were located in the abdomen or adjacent regions. Resection margins were 5 cm for dermatofibrosarcomas and 2 cm for sarcomas and desmoid tumours, with a healthy deep anatomical barrier. Dermatofibrosarcomas were repaired by direct suture in 18% of cases, directed healing in 15%, healing and graft in 45% and flap in 31% of cases. 61% of sarcomas were sutured directly, 7% were treated by directed healing and 23% required cover by a flap. All desmoid tumours were closed by primary suture. The quality of the first surgical resection remains the predominant prognostic factor.
