Colorectal Dis 2024. [PMID: 38858822 DOI: 10.1111/codi.17058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 05/06/2024] [Accepted: 05/20/2024] [Indexed: 06/12/2024]
Abstract
AIM The incidence of colorectal cancer (CRC) in Sweden is increasing in individuals <50 years. This study aimed to examine differences in postoperative 30-day complications and rate of emergency surgeries in CRC patients <50 years at diagnosis compared to older age groups since population-based research on this topic is scarce. METHOD This population-based study included data from the Swedish Colorectal Cancer Registry for patients undergoing CRC resection between 2010 and 2018. Bivariate analysis and logistic regression were used to analyse the relationship between age groups (<50, 50-79 and ≥80 years) and probability of postoperative 30-day complications adjusted for gender, tumour localization, neoadjuvant (chemo)radiotherapy and American Society of Anesthesiologists score. RESULTS In total 33 320 patients were included. Patients <50 years had a lower American Society of Anesthesiologists score, more advanced tumours and received more neoadjuvant treatment. Emergency surgeries were less common in the youngest age group (P < 0.001) as well as overall postoperative 30-day complications: ORadj 0.84 (95% CI 0.74-0.96) compared to those ≥80 years. Surgical complications were more common in age groups <50 and 50-79 years (16.5% and 16.9% respectively) compared to patients ≥80 years (14.1%) (P < 0.001). Anastomotic leakage and intra-abdominal infections were more frequent in patients <50 years (5.7% and 3.5% respectively) compared to age groups 50-79 years (5.1% and 2.8% respectively) and ≥80 years (3.5% and 2.1% respectively) (P < 0.001). Wound infections were more common in the two youngest age groups compared to patients ≥80 years (5.3% vs. 3.7% respectively) (P < 0.001). CONCLUSION Colorectal cancer patients <50 years and 50-79 years had a higher proportion of surgical complications regarding anastomotic leakage, intra-abdominal infections and wound infections but lower overall postoperative complications. The incidence of surgical emergencies was highest amongst patients ≥80 years. Postoperative diagnostic workup in symptomatic individuals <50 years is warranted.

The impact of prehabilitation on outcomes in frail and high-risk patients undergoing major abdominal surgery: A systematic review and meta-analysis. Clin Nutr 2024; 43:629-648. [PMID: 38306891 DOI: 10.1016/j.clnu.2024.01.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/11/2024] [Accepted: 01/15/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND & AIMS Prehabilitation comprises multidisciplinary preoperative interventions including exercise, nutritional optimisation and psychological preparation aimed at improving surgical outcomes. The aim of this systematic review and meta-analysis was to determine the impact of prehabilitation on postoperative outcomes in frail and high-risk patients undergoing major abdominal surgery. METHODS Embase, Medline, CINAHAL and Cochrane databases were searched from January 2010 to January 2023 for randomised clinical trials (RCTs) and observational studies evaluating unimodal (exercise) or multimodal prehabilitation programmes. Meta-analysis was limited to length of stay (primary end point), severe postoperative complications (Clavien-Dindo Classification ≥ Grade 3) and the 6-minute walk test (6MWT). The analysis was performed using RevMan v5.4 software. RESULTS Sixteen studies (6 RCTs, 10 observational) reporting on 3339 patients (1468 prehabilitation group, 1871 control group) were included. The median (interquartile range) age was 74.0 (71.0-78.4) years. Multimodal prehabilitation was applied in fifteen studies and unimodal in one. Meta-analysis of nine studies showed a reduction in hospital length of stay (weighted mean difference -1.07 days, 95 % CI -1.60 to -0.53 days, P < 0.0001, I2 = 19 %). Ten studies addressed severe complications and a meta-analysis suggested a decline in occurrence by up to 44 % (odds ratio 0.56, 95 % CI 0.37 to 0.82, P < 0.004, I2 = 51 %). Four studies provided data on preoperative 6MWT. The pooled weighted mean difference was 40.1 m (95 % CI 32.7 to 47.6 m, P < 0.00001, I2 = 24 %), favouring prehabilitation. CONCLUSION Given the significant impact on shortening length of stay and reducing severe complications, prehabilitation should be encouraged in frail, older and high-risk adult patients undergoing major abdominal surgery.

Abstract
PURPOSE To develop prediction models for short-term mortality risk assessment following colorectal cancer surgery. METHODS Data was harmonized from four Danish observational health databases into the Observational Medical Outcomes Partnership Common Data Model. With a data-driven approach using the Least Absolute Shrinkage and Selection Operator logistic regression on preoperative data, we developed 30-day, 90-day, and 1-year mortality prediction models. We assessed discriminative performance using the area under the receiver operating characteristic and precision-recall curve and calibration using calibration slope, intercept, and calibration-in-the-large. We additionally assessed model performance in subgroups of curative, palliative, elective, and emergency surgery. RESULTS A total of 57,521 patients were included in the study population, 51.1% male and with a median age of 72 years. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.88, 0.878, and 0.861 for 30-day, 90-day, and 1-year mortality, respectively, and a calibration-in-the-large of 1.01, 0.99, and 0.99. The overall incidence of mortality were 4.48% for 30-day mortality, 6.64% for 90-day mortality, and 12.8% for 1-year mortality, respectively. Subgroup analysis showed no improvement of discrimination or calibration when separating the cohort into cohorts of elective surgery, emergency surgery, curative surgery, and palliative surgery. CONCLUSION We were able to train prediction models for the risk of short-term mortality on a data set of four combined national health databases with good discrimination and calibration. We found that one cohort including all operated patients resulted in better performing models than cohorts based on several subgroups.

Abstract
BACKGROUND Surgery can lead to curation in colorectal cancer (CRC) but is associated with significant morbidity. Prehabilitation plays an important role in increasing preoperative physical fitness to reduce morbidity risk; however, data from real-world practice is scarce. This study aimed to evaluate the change in preoperative physical fitness and to evaluate which patients benefit most from prehabilitation. MATERIALS AND METHODS In this single-arm prospective cohort study, consecutive patients undergoing elective colorectal oncological surgery were offered a 3- to 4-week multimodal prehabilitation program (supervised physical exercise training, dietary consultation, protein and vitamin supplementation, smoking cessation, and psychological support). The primary outcome was the change in preoperative aerobic fitness (steep ramp test (SRT)). Secondary outcomes were the change in functional walking capacity (6-minute walk test (6MWT)), and muscle strength (one-repetition maximum (1RM) for various muscle groups). To evaluate who benefit most from prehabilitation, participants were divided in quartiles (Q1, Q2, Q3, and Q4) based on baseline performance. RESULTS In total, 101 patients participated (51.4% male, aged 69.7 ± 12.7 years). The preoperative change in SRT was +28.3 W, +0.36 W/kg, +16.7% (P<0.001). Patients in all quartiles improved at the group level; however, the relative improvement decreased from Q1-Q2, Q2-Q3, and Q3-Q4 (P=0.049). Change in 6MWT was +37.5 m, +7.7% (P<0.001) and 1RM improved with 5.6-33.2 kg, 16.1-32.5% for the various muscle groups (P<0.001). CONCLUSION Prehabilitation in elective oncological colorectal surgery is associated with enhanced preoperative physical fitness regardless of baseline performance. Improvements were relatively larger in less fit patients.

Abstract
BACKGROUND Frailty is associated with worse outcomes and higher healthcare costs. The long waiting time for surgery is a potential 'teachable' moment. We examined the feasibility and safety of a pilot prehabilitation programme on high-risk frail patients undergoing major elective surgery. METHODS A single-centre, retrospective pilot study (Dec 2020-Nov 2021) on a one-stop prehabilitation programme (structured exercise training, nutritional counselling/therapy, and psychological support) in collaboration with geriatricians and allied health professionals. At least 4 weeks before surgery, patients at high risk of frailty or malnutrition, or undergoing major hepatectomy, esophagectomy, pancreaticoduodenectomy, or radical cystectomy, were referred for prehabilitation (2-3 sessions/week). The primary outcomes were the feasibility and safety of prehabilitation. The secondary outcomes were changes in functional, emotional, and nutritional status and days alive and at home within 30 days after surgery (DAH30) associated with prehabilitation. RESULTS Over a 12-month period, 72 out of 111 patients (64.9%) from the Perioperative Medicine Clinic were eligible for prehabilitation, of which 54 (75%) were recruited. The mean (standard deviation) age was 71.9 (6.9) years. The adherence rate to 3 weeks of prehabilitation was high in 52 (96.3%) participants. Prehabilitation improved exercise capacity (P = 0.08), enhanced some functional mobility measures (P = 0.02), and increased nutritional energy (P = 0.04) and protein intakes (P < 0.01). However, prehabilitation-related changes in muscle strength, cognitive function, and emotional resilience were minimal. The median (interquatile range) DAH30 was 19 (14-23) days. No adverse events were reported. CONCLUSIONS This outpatient-based, one-stop multidisciplinary prehabilitation programme was feasible, safe, and improved several measures of patient's physiological reserve and functional capacity.

Abstract
Surgery is one of the leading treatment methods of patients with primary or recurrent malignant neoplasms in the thoracic or abdominal cavity. Extensive abdominal interventions are accompanied by such adverse outcomes as blood loss, hypoxia, inflammation, blood clotting abnormality, emotional and cognitive disorders, that increases the incidence of serious complications and worsens the treatment outcome and life quality in weakened oncological patients. Multimodal pre-rehabilitation before surgery can significantly decrease the incidence and severity of postoperative complications. The rehabilitation complex includes exercise therapy, nutritional and psychological support, smoking cessation and pharmacotherapy. Currently, there are a number of questions facing rehabilitation specialists and oncologists, that are related to the determination of pre-rehabilitation optimal timing and process duration, the choice of specific physical exercises, determining the load intensity. This review presents a current view on understanding of surgical stress in extensive abdominal interventions, its effect on the oncological process course, summarizes the experience of last years in choosing pre-rehabilitation program taking into account pathogenetic mechanisms of surgical stress and individual patient's characteristics. Special attention is paid to the comparison of physical exercises' various types, their action mechanisms at different stages of pathological process, the issues of load dosing during pre-rehabilitation activities.

Abstract
PURPOSE This study aimed to investigate the association of effort-independent variables derived from the preoperative cardiopulmonary exercise test (CPET) with 30-day postoperative complications after elective colorectal surgery. METHODS A multicenter (n=4) retrospective explorative study was performed using data of patients who completed a preoperative CPET and underwent elective colorectal surgery. The preoperative slope of the relation between minute ventilation and carbon dioxide production (VE/VCO2-slope) and the oxygen uptake efficiency slope (OUES), as well as 30-day postoperative complications, were assessed. Multivariable logistic regression analyses and receiver operating characteristic (ROC) curves were used to investigate the prognostic value of the relationship between these preoperative CPET-derived effort-independent variables and postoperative complications. RESULTS Data from 102 patients (60.1% males) with a median age of 72.0 (interquartile range 67.8-77.4) years were analyzed. Forty-four patients (43.1%) had one or more postoperative complications (of which 52.3% general and 77.3% surgical complications). Merely 10 (9.8%) patients had a general complication only. In multivariate analysis adjusted for surgical approach (open versus minimally invasive surgery), the VE/VCO2-slope (odds ratio (OR) 1.08, confidence interval (CI) 1.02-1.16) and OUES (OR 0.94, CI 0.89-1.00) were statistically significant associated with the occurrence of 30-day postoperative complications. CONCLUSION The effort-independent VE/VCO2-slope and OUES might be used to assist in future preoperative risk assessment and could especially be of added value in patients who are unable or unwilling to deliver a maximal cardiorespiratory effort. Future research should reveal the predictive value of these variables individually and/or in combination with other prognostic (CPET-derived) variables for postoperative complications.

Abstract
PURPOSE OF REVIEW Nutrition remains a key focus in the preoptimization of patients undergoing cancer surgery. Given the catabolic nature of cancer, coupled with the physiological insult of surgery, malnutrition (when assessed) is prevalent in a significant proportion of patients. Therefore, robust research on interventions to attenuate the detrimental impact of this is crucial. RECENT FINDINGS As a unimodal prehabilitation intervention, assessment for malnutrition is the first step, as universal supplementation has not been shown to have a significant impact on outcomes. However, targeted nutritional therapy, whether that is enteral or parenteral, has been shown to improve the nutritional state of patients' presurgery, potentially reducing the rate of postoperative complications such as nosocomial infections. As part of multimodal prehabilitation, the situation is more nuanced given the difficulty in attribution of effects to the differing components, and vast heterogeneity in intervention and patient profiles. SUMMARY Multimodal prehabilitation is proven to improve length of hospital stay and postoperative outcomes, with nutrition forming a significant part of the therapy given. Further work is required to look at not only the interplay between the optimization of nutritional status and other prehabilitation interventions, but also how to best select which patients will achieve significant benefit.

Abstract
Directed acyclic graphs (DAGs) are useful tools for visualizing the hypothesized causal structures in an intuitive way and selecting relevant confounders in causal inference. However, in spite of their increasing use in clinical and surgical research, the causal graphs might also be misused by a lack of understanding of the central principles. In this article, we aim to introduce the basic terminology and fundamental rules of DAGs, and DAGitty, a user-friendly program that easily displays DAGs. Specifically, we describe how to determine variables that should or should not be adjusted based on the backdoor criterion with examples. In addition, the occurrence of the various types of biases is discussed with caveats, including the problem caused by the traditional approach using p-values for confounder selection. Moreover, a detailed guide to DAGitty is provided with practical examples regarding minimally invasive surgery. Essentially, the primary benefit of DAGs is to aid researchers in clarifying the research questions and the corresponding designs based on the domain knowledge. With these strengths, we propose that the use of DAGs may contribute to rigorous research designs, and lead to transparency and reproducibility in research on minimally invasive surgery.

Chang MC, Choo YJ, Kim S. Effect of prehabilitation on patients with frailty undergoing colorectal cancer surgery: a systematic review and meta-analysis. Ann Surg Treat Res 2023; 104:313-324. [PMID: 37337603 PMCID: PMC10277181 DOI: 10.4174/astr.2023.104.6.313] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 04/25/2023] [Accepted: 04/25/2023] [Indexed: 06/21/2023] Open
Abstract
Purpose The effect of prehabilitation in patients with frailty undergoing colorectal cancer surgery remains controversial. This meta-analysis aimed to assess the impact of prehabilitation before colorectal surgery on the functional outcomes and postoperative complications in patients with frailty undergoing colorectal cancer surgery. Methods PubMed, EMBASE, Cochrane Library, and Scopus databases were searched for articles published up to November 9, 2022. We included randomized and non-randomized trials in which the effects of prehabilitation in patients with frailty undergoing colorectal cancer surgery were investigated against a control group. Data extracted for our meta-analysis included the 6-minute walk test (6MWT), postoperative incidence of complications (Clavien-Dindo classification ≥IIIa), comprehensive complication index (CCI), and length of stay (LOS) in the hospital. Results Compared with the control group, we found a significant improvement in the incidence of postoperative complications and shorter LOS in the hospital in the prehabilitation group. However, the 6MWT and CCI results showed no significant differences between the 2 groups. Conclusion Prehabilitation in patients with frailty who underwent colorectal cancer surgery improved the incidence of postoperative complications and LOS in the hospital. Hence, clinicians should consider conducting or recommending prehabilitation exercises prior to colorectal cancer surgery in patients with frailty.

Prescribing Exercise to Cancer Patients Suffering from Increased Bone Fracture Risk Due to Metastatic Bone Disease or Multiple Myeloma in Austria-An Inter- and Multidisciplinary Evaluation Measure. Cancers (Basel) 2023; 15:cancers15041245. [PMID: 36831587 PMCID: PMC9954683 DOI: 10.3390/cancers15041245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 02/03/2023] [Accepted: 02/14/2023] [Indexed: 02/18/2023] Open
Abstract
INTRODUCTION In the current absence of specific functional fracture risk assessment technology, the planning of physical exercise interventions for cancer patients suffering from increased bone fracture risk remains a serious clinical challenge. Until a reliable, solely technical solution is available for the clinician, fracture risk assessment remains an inter- and multidisciplinary decision to be made by various medical experts. The aim of this short paper is depicting how this challenge should be approached in the clinical reality according to Austrian experts in cancer rehabilitation, presenting the best-practice model in Austria. Following referral from the specialist responsible for the primary cancer treatment (oncologist, surgeon, etc.), the physiatrist takes on the role of rehabilitation case manager for each individual patient. Fracture risk assessment is then undertaken by specialists in radiology, orthopedics, oncology, and radiation therapy, with the result that the affected bone regions are classified as being at highly/slightly/not increased fracture risk. Following internal clearance, exercise planning is undertaken by a specialist in exercise therapy together with the physiatrist based on the individual's fracture risk assessment. In the case in which the patient shows exercise limitations due to additional musculoskeletal impairments, adjuvant physical modalities such as physiotherapy should be prescribed to increase exercisability. CONCLUSION Exercise prescription for cancer patients suffering from increased fracture risk is an inter- and multidisciplinary team decision for each individual patient.

The effect of preoperative rehabilitation on the prevention of postoperative ileus in colorectal cancer patients. Support Care Cancer 2023; 31:123. [PMID: 36653680 DOI: 10.1007/s00520-023-07585-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Accepted: 01/11/2023] [Indexed: 01/20/2023]
Abstract
PURPOSE Previous research suggests that the preoperative rehabilitation of colorectal cancer patients can reduce postoperative ileus. However, the evidence is insufficient and further research is warranted. This study aimed to investigate whether short-term preoperative rehabilitation, both on an outpatient and inpatient basis, can reduce the incidence of postoperative ileus after colorectal cancer surgery. METHODS This was a retrospective cohort study that drew on data from multicenter electronic medical records. Patients with stage 1-3 colorectal cancer who underwent surgery and postoperative rehabilitation were included. The incidence of postoperative ileus was compared between patients who received short-term preoperative rehabilitation and those who did not. Propensity score adjustment using inverse probability weighting and subgroup analysis by type of surgery was performed. RESULTS Four thousand seventy-six eligible patients (43.4% female; mean age 75.1 ± 10.9 years) were included; 1914 (47.0%) received short-term preoperative rehabilitation. The preoperative rehabilitation group had a significantly lower incidence of postoperative ileus than the no preoperative rehabilitation group (pre-adjustment: 5.5% vs. 9.9%, p < 0.001; post-adjustment: 5.2% vs. 9.0%, p < 0.001). Therefore, preoperative rehabilitation was significantly associated with a lower incidence of postoperative ileus (OR: 0.554, 95% CI: 0.415-0.739, p < 0.001). In an adjusted analysis of surgery type subgroups, the incidence of postoperative ileus was significantly lower in the preoperative rehabilitation group for all types of surgery. CONCLUSION Our study showed that short-term preoperative rehabilitation for patients with stage 1-3 colorectal cancer, both with inpatients and outpatients, significantly reduces the incidence of postoperative ileus.
