Knowledge, attitudes and practice of surgeons regarding nutritional support in CRS and HIPEC patients: Are we missing something?

Knowledge, attitudes, and practices of primary caregivers of gastric cancer patients regarding postoperative dietary management

BACKGROUND

Family caregivers of gastric cancer (GC) patients after gastrectomy have a strong demand for nutrition knowledge. This study investigates the knowledge, attitudes, and practices (KAP) of primary caregivers of GC patients regarding postoperative dietary management.

METHODS

We conducted a cross-sectional study, collecting data through questionnaire distribution. Demographic information of the respondents and KAP scores were assessed and analyzed.

RESULTS

Of 508 included participants, majority were female (59.84%) urban residents (78.94%), aged 40-60 years (53.15%). Caretakers were primarily spouses of GC patient (50.39%) or parents (10.43%), only child (12.99%) or non-only child (24.21%). Notable percentage of poor knowledge and practice was found among participants (45.05% and 40.55%, respectively), while attitude was predominantly positive (99.41%). Correlation analysis revealed a weak positive correlation between knowledge and attitude scores (r = 0.150, P < 0.001) and negative link to practice scores (r=-0.228, P < 0.001); attitude scores were positively correlated with practice (r = 0.117, P = 0.008). Multivariate logistic regression analysis found that higher attitude scores were independently associated with higher practice scores (OR = 1.360; 95%CI, 1.223-1.513), P < 0.001), while higher knowledge scores (OR = 0.684; 95%CI, 0.575-0.815), P < 0.001), older age (OR = 0.951; 95%CI, 0.918-0.985), P = 0.005), duration of caregiving > 3 months (3-6 months (OR = 0.415; 95%CI, 0.193-0.894, P = 0.025); 6 months-1 year (OR = 0.269; 95%CI, 0.120-0.606), P = 0.002); >1 year (OR = 0.290; 95%CI, 0.120-0.705), P = 0.006), and follow-up location after patient's surgery (OR = 0.072 (0.033-0.160), P < 0.001) were independently associated with lower practice scores.

CONCLUSIONS

Family caregivers of GC patients that participated in this study demonstrated moderate knowledge and practice, but positive attitude towards dietary management after gastrectomy.

The relationship between baseline nutritional status with subsequent parenteral nutrition and clinical outcomes in cancer patients undergoing cytoreductive surgery: a retrospective study

Introduction

Hyperthermic Intraperitoneal Chemotherapy (HIPEC) with Cytoreductive Surgery (CRS) is the preferred treatment for peritoneal malignancies. This highly complex operation is associated with a high incidence of complications, particularly due to malnutrition. This study aimed to investigate the potential association between preoperative nutritional status and postoperative clinical outcomes in adult cancer patients who underwent CRS/HIPEC for peritoneal malignancy.

Methods

A retrospective study with 140 adult cancer patients, on parenteral nutrition (PN) (n = 40) and not on PN (n = 100) who underwent CRS with or without HIPEC, was conducted.

Results

Patients who received PN had significantly longer post-operative, hospital, and ICU LOS than those who did not (p = 0.001). ICU admission was significantly higher in the non-PN receiving group compared to the PN receiving group. When compared to the PN group, the majority of patients not receiving PN were at low risk of malnutrition (91% vs. 75%, p = 0.020), whereas 17.5% of PN patients were at risk of malnutrition during hospitalization. Multiple regression analyses revealed a strong positive relationship between patients with increased risk of malnutrition and ICU LOS (p = 0.047).

Discussion

Routine preoperative nutrition assessment is essential to identify patients who are at higher nutritional risk, and nutrition support should be provided preoperatively.

A global analysis of nutrition support practices in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal malignancy

BACKGROUND

Perioperative nutritional care has been identified as an important factor in the management of patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Nevertheless, there is no published consensus on best practice for nutritional management specific to this patient group. The purpose of this study was to identify the current nutrition care practices among international centres performing CRS and HIPEC for patients with peritoneal malignancy.

METHODS

An online survey was developed and sent to experienced CRS and HIPEC centres. The survey questions covered clinician and institution demographics, formal nutrition care pathways, pre-operative nutrition care, post-operative nutrition support and post-discharge nutritional follow-up.

RESULTS

Eighty-two centres were contacted, and 42 responses were received. Respondents were from 20 different countries and were mostly dietitians (71%). Nutrition assessments were frequently completed (52% pre-operatively and 86% post-operatively) and most centres used a validated nutrition screening or assessment tool (79%). Perioperative nutrition support with respect to the use of enteral nutrition, parenteral nutrition and enhanced recovery after surgery varied widely between centres. The use of routine parenteral and enteral nutrition was significantly higher in Europe compared with other locations (p = 0.028).

CONCLUSIONS

Nutrition care is pivotal and has been positively integrated into the complex management of patients undergoing CRS and HIPEC globally, however variation in practice is evident. The findings highlight a unique opportunity to collaboratively investigate the role nutrition plays in determining outcomes and to identify the most appropriate nutrition support methods to achieve improved clinical outcomes for these high-risk patients.

The Prevalence and Impact of Nutritional Risk and Malnutrition in Gastrointestinal Surgical Oncology Patients: A Prospective, Observational, Multicenter, and Exploratory Study

A prospective, observational, multicenter, and exploratory study was conducted in 469 gastrointestinal cancer patients undergoing elective surgery. The Malnutrition Universal Screening Tool (MUST) and the Global Leadership Initiative on Malnutrition (GLIM) criteria were used to assess nutritional risk. On admission, 17.9% and 21.1% of patients were at moderate (MUST score 1) and severe (MUST score ≥ 2) nutritional risk, respectively. The GLIM criteria used in patients with a MUST score ≥ 2 showed moderate malnutrition in 35.3% of patients and severe in 64.6%. Forty-seven percent of patients with a MUST score ≥ 2 on admission had the same score at discharge, and 20.7% with a MUST score 0 had moderate/severe risk at discharge. Small bowel, esophageal, and gastric cancer and diabetes were predictors of malnutrition on admission. Complications were significantly higher among patients with a MUST score 1 or ≥2 either on admission (p = 0.001) or at discharge (p < 0.0001). In patients who received nutritional therapy (n = 231), 43% continued to have moderate/severe nutritional risk on discharge, and 54% of those with MUST ≥ 2 on admission maintained this score at discharge. In gastrointestinal cancer patients undergoing elective surgery, there is an urgent need for improving nutritional risk screening before and after surgery, as well as improving nutritional therapy during hospitalization.

Perioperative nutritional assessment and interventions in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC): A systematic review

BACKGROUND

Peritoneal carcinomatosis is a catabolic state and cytoreductive surgery (CRS) is a high morbidity operation. Optimising perioperative nutrition is crucial to improve outcomes. This systematic review sought to examine literature describing clinical outcomes related to preoperative nutrition status and nutrition interventions in patients undergoing CRS with hyperthermic intraperitoneal chemotherapy (HIPEC).

METHODS

A systematic review was registered with PROSPERO (300326). A search of eight electronic databases was undertaken on 8th May 2022 and reported according to the PRISMA statement. Studies reporting nutrition status through use of screening and assessment tools, nutrition interventions or nutrition-related clinical outcomes for patients undergoing CRS with HIPEC were included.

RESULTS

Of 276 screened studies, 25 studies were included for review. Commonly used nutrition assessment tools for CRS-HIPEC patients included Subjective Global Assessment (SGA), sarcopenia assessment with computed tomography, preoperative albumin, and body mass index (BMI). Three retrospective studies compared SGA with postoperative outcomes. Malnourished patients were more likely to have postoperative infectious complications (p = 0.042 SGA-B, p = 0.025 SGA-C). Malnutrition was significantly associated with increased hospital length of stay (LOS) in two studies (p = 0.006, p = 0.02), and with overall survival in another study (p = 0.006). Eight studies analysing preoperative albumin levels reported conflicting associations with postoperative outcomes. BMI in five studies was not associated with morbidity. One study did not support routine nasogastric tube (NGT) feeding.

CONCLUSIONS

Preoperative nutritional assessment tools, including SGA and objective sarcopaenia measures, have a role in predicting nutritional status for CRS-HIPEC patients. Optimisation of nutrition is important for preventing complications.

Effect of malnutrition and nutritional support to reduce infections in elderly hospitalized patients with cancer: A multicenter survey in China

OBJECTIVES

Malnutrition is common among elderly patients with cancer, and greatly affects patients' quality of life. Malnutrition is a key factor in the development of systemic, chronic, low-grade inflammation that can exacerbate.

METHODS

A total of 633 elderly patients with cancer from 29 tertiary public hospitals in 14 cities in China were selected as the research subjects. Physical examination, questionnaire survey, medical history collection, and blood index detection were performed on the research subjects to analyze the relationship between malnutrition, nutritional support, and infection status.

RESULTS

There was no significant difference in infection rate among elderly hospitalized patients with cancer and different cancer types, cancer stages, or therapy methods (P > 0.05). The proportion of vomiting, loss of appetite, depression, and physical fatigue in patients with good nutritional status were lower than in patients with moderate or severe malnutrition (P < 0.05). Nutritional support is crucial for the nutritional status of elderly patients with cancer, and patients without special nutritional guidance are more likely to develop infection (P < 0.05). After adjusting for confounding variables, the results of the logistic regression analysis showed that oral nutritional supplements (odds ratio [OR]: 0.088; 95% confidence interval [CI], 0.015-0.514), parenteral nutrition (OR: 0.091; 95% CI, 0.011-0.758), and individualized nutritional guidance (OR: 0.026; 95% CI, 0.003-0.202) were all protective factors associated with cancer infection.

CONCLUSIONS

Many elderly hospitalized patients with cancer have local or systemic infections, and good nutrition is associated with lower rates of infection. Receiving nutritional guidance or support is associated with lower infection rates in elderly patients with cancer.

Knowledge and Practices of Digestive Surgeons concerning Specialized Nutritional Support in Cancer Patients: A Survey Study

A survey study based on a 21-item questionnaire was conducted to assess knowledge and practices of digestive surgeons focused on nutritional support in gastrointestinal cancer patients. At least 5 staff digestive surgeons from 25 tertiary care hospitals throughout Spain were invited to participate and 116 accepted. Malnutrition was correctly defined by 81.9% of participants. In patients undergoing major abdominal surgery, 55.2% considered that preoperative nutritional support is indicated in all patients with malnutrition for a period of 7-14 days. For the diagnosis of malnutrition, only 18.1% of participants selected unintentional weight loss together with a fasting or semi-fasting period of more than one week. Regarding the advantages of enteral infusion, 93.7% of participants considered preservation of the integrity of the intestinal mucosa and barrier function, and in relation to peripheral parenteral nutrition, 86.2% selected the definition of nutrient infusion through a peripheral vein and 81.9% its indication for less than 7 days. Digestive surgeons had a limited knowledge of basic aspects of clinical nutrition in cancer patients, but there was some variability regarding clinical practice in individual cases. These findings indicate the need to develop standardized clinical protocols as well as a national consensus on nutrition support in cancer patients.

Recognising undernutrition in a community hospital: the nursing judgement is insufficient

Introduction

Standardised nutritional screening methods improve the rate of recognising older patients with undernutrition, which is strongly encouraged in hospitals and residential settings. Therefore, our study compared the rates of identifying undernutrition before and after introducing the Mini Nutritional Assessment (MNA®) in a community hospital.

Methods

This was a single-centre, retrospective, observational before–after study. Participants were subjects aged 65 years or older, admitted to a community hospital from May 2018 to December 2020. The nursing assessment at admission included the MNA® from January 2020. The prevalence of undernutrition gathered by nursing diagnoses from 2018 to 2019 was compared with data obtained using the MNA® in 2020. Then, a confirmatory analysis was conducted to compare the prevalence of undernutrition in 2020 when both nursing diagnoses and the MNA® were used.

Results

We analysed data of approximately 316 patients (238 before and 78 after introducing the MNA®). Overall, results showed that 47.1% (n = 149) of the patients were undernourished. As observed, the prevalence of undernutrition was 38.6% (n = 92) in 2018–2019 and 73.1% (n = 57) in 2020 (p < 0.001). In 2020, however, 38.5% of patients (n = 30) were identified as undernourished using the MNA® but not using nursing diagnoses. Therefore, the correlation between these two methods was poor (Pearson’s correlation 0.169, p = 0.14).

Conclusion

Identifying elderly patients with undernutrition significantly increased after introducing the MNA®. Undernutrition is a common condition that should be systematically screened using a validated tool to activate personalised nutritional interventions promptly.

The prognostic value of skeletal muscle index on clinical and survival outcomes after cytoreduction and HIPEC for peritoneal metastases from colorectal cancer: A systematic review and meta-analysis

BACKGROUND

Cytoreductive surgery (CRS) and hypertermic intraperitoneal chemotherapy (HIPEC) represent the most effective strategy to manage peritoneal metastases (PM). This systematic review and meta-analysis aimed to assess the impact of body composition on clinical outcomes in patients with PM.

METHODS

A systematic literature search was performed using Medline, Web of Science and EMBASE databases from inception to the 20^st August 2020. Data were independently extracted by 3 authors. Newcastle-Ottawa Scale was used to assess quality and risk of bias of studies. Pooled analyses were performed using Mantel-Haenszel method to estimate overall effect size with mean differences or odd ratios (ORs) and 95% confidence interval (CI). The primary outcome was postoperative complication (POC) rate, while secondary outcomes were severe POC and postoperative mortality.

RESULTS

A total of 4 studies were included in the systematic review and meta-analysis, including 582 patients. A significant association between low skeletal muscle mass and POC was found (OR 1.45, 95% CI 1.04 to 2.03; p = 0.03), while no differences were found in terms operative time, estimated blood loss, length of hospital stay, and postoperative mortality (p > 0.05).

CONCLUSIONS

Low skeletal muscle mass at diagnosis is a valid prognostic factor for POC development in colorectal and PM patients undergoing CRS. Prospective and larger studies are needed to better investigate the role of CT scan derived body composition and to understand how to implement this tool in clinical practice.

Perioperative factors predicting delayed enteral resumption and hospital length of stay in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: Retrospective cohort analysis from a single centre in India

Background and Aims:

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is an extensive procedure associated with significant morbidity, delay in return of gastrointestinal function and discharge from hospital. Our aim was to assess perioperative factors influencing enteral resumption (ER) and length of stay in the hospital (LOS) in CRS-HIPEC.

Methods:

A retrospective analysis was conducted in a major tertiary cancer centre. Sixty-five patients who underwent CRS-HIPEC between July 2014 and March 2019 were included in the study. The perioperative data were collected from patient records. The primary outcome measure was day of oral resumption of 500 ml of clear fluids and secondary outcome was the LOS. Univariate and multivariate logistic regression analysis was done for the various continuous and categorical perioperative variables for both ER and LOS to elicit the magnitude of risk for both outcomes.

Results:

Univariate logistic regression revealed that peritoneal carcinomatosis index score (PCI), duration of surgery, blood loss and postoperative ventilation influenced both ER and LOS. Serum albumin, plasma usage and total peritonectomy affected only the LOS but not ER. Multivariate analysis showed that duration of surgery (P = 0.006) and quantum of intravenous fluid infused (P = 0.043) were statistically associated with ER, while serum albumin level (P = 0.025) and postoperative ventilation (P = 0.045) were independently predictive of LOS.

Conclusion:

CRS-HIPEC is an extensive surgery and multiple factors are associated with ER; of these, duration of surgery and intraoperative fluid therapy are significant factors. Low serum albumin and prolonged postoperative ventilation are associated with increased LOS.
