Preoperative nutrition and exercise intervention in frailty patients with gastric cancer undergoing gastrectomy

Boosting recovery before surgery: The impact of prehabilitation on upper gastrointestinal cancer patients - A quantitative comparative analysis

BACKGROUND

Emerging research presents divergent perspectives on the efficacy of prehabilitation for patients scheduled for surgery due to upper gastrointestinal (GI) cancers, capturing the attention of both the scientific community and surgical professionals. This quantitative comparative analysis seeks to assess the association of prehabilitation to ameliorate postoperative outcomes in individuals with upper GI cancers, thereby providing a comprehensive evaluation of its potential benefits within a surgical context.

MATERIALS AND METHODS

Medline, Embase, Cochrane Library and Web of Science were searched up to February 2024. Studies reporting the association between prehabilitation, and postoperative complications, readmissions or other outcomes of interest were included. Fixed or random effect models were used, and forest plots were applied to show the results of the quantitative comparative analysis.

RESULTS

A total of 198 studies were initially screened based on titles and abstracts, with 129 studies subsequently excluded. Overall, 69 full-text studies were identified, of which 12 studies were finally included for qualitative analysis in the quantitative comparative analysis after determining whether the inclusion and exclusion criteria were met. The pooled results indicated that prehabilitation significantly reduced the overall postoperative complication rates in patients with upper GI cancer undergoing surgical therapy with the pooled OR of 0.59 (95%CI: 0.39-0.88). Moreover, prehabilitation was also shown to be a protective factor of pulmonary complications (OR: 0.54, 95%CI: 0.36-0.80) and ICU readmissions (OR: 0.23, 95%CI: 0.06-0.89).

CONCLUSION

The correlation between prehabilitation and a reduction in overall postoperative complications, pulmonary complications, and ICU readmissions among patients with upper GI cancer is substantiated by significant data. This pivotal finding necessitates further empirical investigation to validate these initial results and ascertain the clinical efficacy of prehabilitation protocols, thereby informing future surgical practice strategies.

Development of a modified nutritional index model based on nutritional status and sarcopenia to predict long-term survival and chemotherapy benefits in elderly patients with advanced gastric cancer

BACKGROUND

Elderly patients with advanced gastric cancer have poor prognoses. This study aims to develop a prediction model for long-term survival after radical surgery and to identify patients who may benefit from chemotherapy.

METHODS

Data from 555 elderly patients with advanced gastric cancer admitted to two medical centers from 2009 to 2018 were retrospectively analyzed. Sarcopenia was combined with the Controlling Nutritional Status (CONUT) score to create a modified nutritional index (mCONUT). Cox regression analyses were used to develop a novel nomogram prediction model (mCNS) that combined mCONUT, pN, and tumor size, and its performance was further verified both internally and externally.

RESULTS

Multivariate Cox analysis revealed that tumor size, pN, and mCONUT were independent prognostic risk factors for overall survival (OS). The mCNS model showed good fit and high predictive value (AUC: training set 0.711; validation set 0.707), outperforming the pTNM model (p < 0.05). To further investigate the association between the model and adjuvant chemotherapy, we categorized the model into two risk groups: a high-risk group and a low-risk group. Further analysis revealed that, in the low-risk group, the OS and recurrence-free survival(RFS) for patients receiving adjuvant chemotherapy was significantly better than that of those who did not receive chemotherapy (p = 0.047,p = 0.019). In the high-risk group, this result was not observed (p = 0.120, p = 0.053).

CONCLUSION

The mCNS model has high predictive value in predicting long-term survival of elderly patients with advanced gastric cancer. Patients with mCNS-L were able to benefit from chemotherapy after laparoscopic radical gastrectomy.

Prehabilitation-A Simple Approach for Complex Patients: The Results of a Single-Center Study on Prehabilitation in Patients with Ovarian Cancer Before Cytoreductive Surgery

Background/Objectives: Prehabilitation is a low-cost, safe procedure with no side effects, and it may have a positive impact on postoperative outcomes. However, it is not widely implemented. Our study aimed to assess the impact of prehabilitation on postoperative outcomes in patients with ovarian cancer within the field of gynecological oncology. Methods: We analyzed 110 patients with ovarian cancer who participated in a prehabilitation program before cytoreductive surgery. Based on the results of a 6-min walk test (6MWT), patients were divided into two groups: Group A (patients who improved their 6MWT results) and Group B (patients who did not improve their 6MWT results). Results: Patients in Group A demonstrated better postoperative outcomes. The length of hospital stay was significantly shorter in Group A compared to Group B (median 7 [5, 9] vs. 9 [6, 17], p = 0.032). Group A also had a lower overall number of complications and also fewer complications, as summarized by the Clavien-Dindo classification, compared to Group B. Conclusions: Patient adherence to prehabilitation recommendations was adequate. Prehabilitation was associated with improved postoperative outcomes, including shorter hospital stays and fewer complications. These benefits were more pronounced with higher patient compliance with the prehabilitation program and improvements were recorded in preoperative physical capacity.

Multicomponent perioperative interventions to improve outcomes for frail patients: a systematic review

BACKGROUND

Preoperative frailty is associated with increased risk of adverse outcomes. In 2017, McIsaac and colleagues' systematic review found that few interventions improved outcomes in this population and evidence was low-quality. We aimed to systematically review the evidence for multicomponent perioperative interventions in frail patients that has emerged since McIsaac et al.'s review.

METHODS

PUBMED, EMBASE, Cochrane, and CINAHL databases were searched for English-language studies published since January 1, 2016, that evaluated multicomponent perioperative interventions in patients identified as frail. Quality was assessed using the National Institute of Health Quality Assessment Tool. A narrative synthesis of the extracted data was conducted.

RESULTS

Of 2835 articles screened, five studies were included, all of which were conducted in elective oncologic gastrointestinal surgical populations. Four hundred and thirteen patients were included across the five studies and the mean/median age ranged from 70.1 to 87.0 years. Multicomponent interventions were all applied in the preoperative period. Two studies also applied interventions postoperatively. All interventions addressed exercise and nutritional domains with variability in timing, delivery, and adherence. Multicomponent interventions were associated with reduced postoperative complications, functional deterioration, length of stay, and mortality. Four studies reported on patient-centred outcomes. The quality of evidence was fair.

CONCLUSIONS

This systematic review provides evidence that frail surgical patients undergoing elective oncologic gastrointestinal surgery may benefit from targeted multicomponent perioperative interventions. Yet methodological issues and substantial heterogeneity of the interventions precludes drawing clear conclusions regarding the optimal model of care. Larger, low risk of bias studies are needed to evaluate optimal intervention delivery, effectiveness in other populations, implementation in health care settings and ascertain outcomes of importance for frail patients and their carers.

The impact of prehabilitation on outcomes in frail and high-risk patients undergoing major abdominal surgery: A systematic review and meta-analysis

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.

Effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer: a systematic review and meta-analysis

PURPOSE

To evaluate the effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer.

METHODS

We conducted a systematic search of the PubMed, Embase, CINAHL, Web of Science, and Cochrane Library (CENTRAL) databases from database inception to May 5, 2023, for randomized controlled trials (RCTs) and cohort studies that investigated prehabilitation in the context of esophagogastric cancer. A random-effects model was used for meta-analysis.

RESULTS

We identified 2,994 records and eventually included 12 studies (6 RCTs and 6 cohort studies) with a total of 910 patients. According to random-effects pooled estimates, prehabilitation reduced the incidence of all complications (RR = 0.79, 95% CI: 0.66 to 0.93, P = 0.006), pulmonary complications (RR = 0.61, 95% CI: 0.47 to 0.79, P = 0.0002), and severe complications (RR = 0.63, 95% CI: 0.47 to 0.84, P = 0.002), and shortened the length of stay (MD = -1.92, 95% CI: -3.11 to -0.73, P = 0.002) compared to usual care. However, there were no statistically significant differences in 30-day readmission rates or in-hospital mortality. Subgroup analysis showed that multimodal prehabilitation was effective in reducing the risk of all complications and severe complications, while unimodal prehabilitation was not.

CONCLUSIONS

Our findings suggested that prehabilitation may be beneficial in reducing postoperative complications and length of stay. We recommend preoperative prehabilitation to improve postoperative outcomes and hasten recovery following esophagogastric cancer surgery, and multimodal prehabilitation seems to be more advantageous in reducing complications. However, further studies are needed to confirm these results.

Value of sarcopenia in the resection of colorectal liver metastases-a systematic review and meta-analysis

Introduction

Sarcopenia is defined as a decline in muscle function as well as muscle mass. Sarcopenia itself and sarcopenic obesity, defined as sarcopenia in obese patients, have been used as surrogates for a worse prognosis in colorectal cancer. This review aims to determine if there is evidence for sarcopenia as a prognostic parameter in colorectal liver metastases (CRLM).

Methods

PubMed, Embase, Cochrane Central, Web of Science, SCOPUS, and CINAHL databases were searched for articles that were selected in accordance with the PRISMA guidelines. The primary outcomes were overall survival (OS) and disease-free survival (DFS). A random effects meta-analysis was conducted.

Results

After eliminating duplicates and screening abstracts (n = 111), 949 studies were screened, and 33 publications met the inclusion criteria. Of them, 15 were selected after close paper review, and 10 were incorporated into the meta-analysis, which comprised 825 patients. No significant influence of sarcopenia for OS (odds ratio (OR), 2.802 (95% confidence interval (CI), 1.094-1.11); p = 0.4) or DFS (OR, 1.203 (95% CI, 1.162-1.208); p = 0.5) was found, although a trend was defined toward sarcopenia. Sarcopenia significantly influenced postoperative complication rates (OR, 7.905 (95% CI, 1.876-3.32); p = 0.001) in two studies where data were available.

Conclusion

Existing evidence on the influence of sarcopenia on postoperative OS as well as DFS in patients undergoing resection for CRLM exists. We were not able to confirm that sarcopenic patients have a significantly worse OS and DFS in our analysis, although a trend toward this hypothesis was visible. Sarcopenia seems to influence complication rates but prospective studies are needed.

Usefulness of the cachexia index as a prognostic indicator for patients with gastric cancer

Aim

Cachexia is associated with the morbidity and mortality of cancer patients. The cachexia index (CXI) is a novel biomarker of cachexia associated with the prognosis for certain cancers. This study analyzed the relationship between CXI with long-term outcomes of gastric cancer patients.

Methods

We included 175 gastric cancer patients who underwent curative gastrectomy at our hospital between January 2011 and October 2019. The CXI was calculated using skeletal muscle index, serum albumin level, and neutrophil-to-lymphocyte ratio. The prognostic value of CXI was investigated by univariate and multivariate Cox hazard regression models adjusting for potential confounders.

Results

In the multivariate analyses, tumor location (hazard ratio [HR], 0.23; 95% confidence interval [CI], 0.11-0.49; p < 0.01), disease stage (HR, 15.4; 95% CI, 4.18-56.1; p < 0.01), and low CXI (HR, 2.97; 95% CI, 1.01-8.15; p = 0.03) were independent and significant predictors of disease-free survival. Disease stage (HR, 9.88; 95% CI, 3.53-29.1; p < 0.01) and low CXI (HR, 4.07; 95% CI, 1.35-12.3; p < 0.01) were independent and significant predictors of overall survival. The low CXI group had a lower body mass index (p = 0.02), advanced disease stage (p = 0.034), and a lower prognostic nutritional index (p < 0.01).

Conclusions

Cachexia index is associated with a poor prognosis for gastric cancer, suggesting the utility of comprehensive assessment using nutritional, physical, and inflammatory status.

Adverse outcomes and health-ecological influencing factors of preoperative frailty among elderly patients with gastric cancer

PURPOSE

Frailty is defined as a state of decreased physiologic reserves arising from cumulative deficits in multiple homeostatic systems, which is important in the field of clinical oncology. We aimed to explore the relationship between preoperative frailty and adverse outcomes, and systematically analyze the factors influencing frailty based on the health ecology model among elderly gastric cancer patients.

METHODS

A observational study was conducted to select 406 elderly patients who would undergo gastric cancer surgery at a tertiary hospital. The logistic regression model was used to examine the relationship between preoperative frailty and adverse outcomes, including total complications, prolonged length of stay (PLOS), and 90-day hospital readmission. Based on the health ecology model, the factors which may influence frailty were collected from four levels. Univariate and multivariate analysis were utilized to determine the factors influencing preoperative frailty.

RESULTS

Preoperative frailty was associated with total complications (odds ratio [OR] 2.776, 95% confidence interval [CI] 1.588-4.852), PLOS (OR 2.338, 95%CI 1.342-4.073), and 90-day hospital readmission (OR 2.640, 95% CI 1.275-5.469). Besides, nutritional risk (OR 4.759, 95% CI 2.409-9.403), anemia (OR 3.160, 95% CI 1.751-5.701), number of comorbidity ≥ 2 (OR 2.318, 95% CI 1.253-4.291), low physical activity level (OR 3.069, 95% CI 1.164-8.092), apathetic attachment (OR 2.656, 95% CI 1.457-4.839), personal monthly income ≤ 1000 yuan (OR 2.033, 95% CI 1.137-3.635) and anxiety (OR 2.574, 95% CI 1.311-5.053) were independent risk factors for frailty. High physical activity level (OR 0.413, 95% CI 0.208-0.820) and improved objective support (OR 0.818, 95% CI 0.683-0.978) were independent protective factors for frailty.

CONCLUSIONS

Preoperative frailty was associated with multiple adverse outcomes and could be affected by factors of different dimensions from the health ecology perspective, including nutrition, anemia, comorbidity, physical activity, attachment style, objective support, anxiety, and income, which can guide the formation of a comprehensive prehabilitation for frailty among elderly gastric cancer patients.

Heterogeneity of vulnerability and taste changes in older cancer patients undergoing chemotherapy: a latent class analysis

PURPOSE

Taste changes and vulnerability are commonly co-occurring in oncology patients undergoing chemotherapy. However, few studies explored the association and the inter-individual variability of these two conditions. This study aimed to identify heterogeneous subtypes of vulnerability and taste changes in older cancer patients undergoing chemotherapy, and explore individuals' characteristics and risk factors.

METHODS

In this cross-sectional study, the latent class analysis (LCA) was conducted to identify the heterogeneous subgroups of patients with distinct vulnerability and taste change profiles. Differences in sociodemographic and clinical characteristics among the subpopulation were evaluated using parametric and nonparametric tests. Multinomial logistic regression was performed to investigate predictors of taste change-vulnerability subgroup classification.

RESULTS

Three subgroups of those older cancer survivors were identified from the LCA: Class 1 (27.5%)-"Moderate taste change and low vulnerability", Class 2 (29.0%)-"Low taste change and moderate vulnerability", Class 3 (43.5%)-"High taste change and high vulnerability". 98.9% of Class 3 reported taste changes and 54.0% reported vulnerability. Results from multinomial logistic regression indicated that patients in Class 3 were more likely to report experiencing mouth dryness and high blood pressure, and have received more than 3 cycles of chemotherapy.

CONCLUSION

The findings could provide new insights into the association between taste changes and vulnerability in older cancer adults receiving chemotherapy. Identifying different latent classes of taste changes and vulnerability would be helpful for developing interventions tailored to the heterogeneous survivors.

Harnessing interventions during the immediate perioperative period to improve the long-term survival of patients following radical gastrectomy

Although the incidence and mortality of gastric cancer (GC) have been decreasing steadily worldwide, especially in East Asia, the disease burden of this malignancy is still very heavy. Except for tremendous progress in the management of GC by multidisciplinary treatment, surgical excision of the primary tumor is still the cornerstone intervention in the curative-intent treatment of GC. During the relatively short perioperative period, patients undergoing radical gastrectomy will suffer from at least part of the following perioperative events: Surgery, anesthesia, pain, intraoperative blood loss, allogeneic blood transfusion, postoperative complications, and their related anxiety, depression and stress response, which have been shown to affect long-term outcomes. Therefore, in recent years, studies have been carried out to find and test interventions during the perioperative period to improve the long-term survival of patients following radical gastrectomy, which will be the aim of this review.

Surgical prehabilitation in older and frail individuals: a scoping review

Background:

Older individuals who are scheduled for elective procedures often have co-morbidities at baseline and may be classified as frail. Both older age and frailty are associated with poor fitness and preoperative deconditioning, which can be predictors of postoperative complications. Prehabilitation aims to improve preoperative health in order to reduce complications and expedite postoperative recovery. To date, the effect of prehabilitation on improving outcomes in older and frail individuals is unclear, and the evidence in support of multi-modal treatments is evolving.

Methods:

In this scoping review, searches of PubMed and Cochrane Library between August 2012 and August 2022 were performed to identify studies investigating the efficacy of prehabilitation prior to surgical procedures.

Results:

A total of 36 articles were included in the review. Most of these examined the efficacy of unimodal (n=21) prehabilitation interventions, most commonly exercise therapy. Multimodal prehabilitation programs (n=15) included a variety of intervention components (e.g., exercise training, nutrition, psychological intervention or geriatric consultation). The most commonly studied populations were patients with gastrointestinal cancer (mostly colorectal cancer). Exercise therapy and multimodal interventions are likely to be of greatest impact on postoperative functional decline in patients awaiting total knee or hip arthroplasty, and cancer-related resection surgery (e.g., due to colorectal, gastric or lung cancer) in older and frail patients.

Conclusions:

Presurgical prehabilitation showed the potential to diminish postoperative outcomes in older and frail patients prior to surgery. However, adequately powered, randomized controlled, assessor blinded intervention trials demonstrating overall benefit of prehabilitation are needed.

Aims

This scoping review aims to summarize the current literature on the efficacy of prehabilitation in older and frail individuals who are undergoing surgical procedures in order to support clinical protocols and inform future research.

Effectiveness of a personalized digital exercise and nutrition-based rehab program for patients with gastric cancer after surgery: Study protocol for a randomized controlled trial

Background

Patients with gastric cancer often encounter impaired quality of life and reduced tolerability to adjuvant treatments after surgery. Weight preservation is crucial for the overall prognosis of these patients, and exercise and supplemental nutrition play the main role. This study is the first randomized clinical trial to apply personalized, treatment stage-adjusted digital intervention with wearable devices in gastric cancer rehabilitation intervention for 12 months, commencing immediately after surgery.

Methods

This is a prospective, multicenter, two-armed, randomized controlled trial and aims to recruit 324 patients from two hospitals. Patients will be randomly allocated to two groups for 1 year of rehabilitation, starting immediately after the operation: a personalized digital therapeutic (intervention) group and a conventional education-based rehabilitation (control) group. The primary objective is to clarify the effect of mobile applications and wearable smart bands in reducing weight loss in patients with gastric cancer. The secondary outcomes are quality of life measured by the EORTC-QLQ-C30 and STO22; nutritional status by mini nutrition assessment; physical fitness level measured by grip strength test, 30-s chair stand test and 2-min walk test; physical activity measured by IPAQ-SF; pain intensity; skeletal muscle mass; and fat mass. These measurements will be performed on enrollment and at 1, 3, 6, and 12 months thereafter.

Conclusions

Digital therapeutic programs include exercise and nutritional interventions modified by age, body mass index, surgery type and postoperative days. Thus, expert intervention is pivotal for precise and safe calibration of this program.

Prognostic impact of frailty after gastrectomy in elderly gastric cancer patients

BACKGROUND

Frailty plays a crucial role in cancer patients who have received surgery in this recent aging society. We aimed to investigate frailty as a prognostic factor in elderly gastric cancer (GC) patients who underwent curative gastrectomy.

METHODS

We analyzed 86 elderly (over 75 years old) GC patients who underwent curative gastrectomy. Patients were assigned to two groups;frailty group (n=29) and no-frailty group (n=57). Clinicopathological values were compared between the two groups.

RESULTS

The OS rate of the frailty group was significantly poorer than that of the no-frailty group (5-yr OS rate;frailty group 52.49% vs. no-frailty group 74.87%, p<0.05). Multivariate analysis of the OS showed that frailty tended to be significant prognostic factor (p=0.09). The DFS rate of the frailty group was significantly poorer than that of the no-frailty group (5-yr DFS rate;frailty group 42.30% vs. no-frailty group 71.55%, p<0.05). Multivariate analysis of the DFS showed that frailty tended to be significant prognostic factor (p=0.14).

CONCLUSION

We identified the clinical impact of frailty prognostic factor for elderly GC patients who underwent gastrectomy. J. Med. Invest. 70 : 423-429, August, 2023.
