Frailty is a useful predictive marker of postoperative complications after pancreaticoduodenectomy

Frailty and Cancer Prognosis

PURPOSE OF REVIEW

This review aims to summarize the current evidence regarding the prognostic role of frailty in older patients diagnosed with cancer and to explore the evidence regarding its prognostic implications in cancer survivors.

RECENT FINDINGS

Frailty has been consistently associated with mortality/overall survival, postoperative complications, short- and long-term postoperative mortality, length of stay, among other adverse health-related outcomes in several oncological contexts. The possible association between frailty and treatment toxicity has been less explored, however most studies suggest frailty is a predictor of treatment induced toxicity. In addition, in cancer survivors, frailty is a risk factor for cardiovascular disease, incident type 2 diabetes mellitus, mortality, altered cognitive performance and increased symptom severity. Due to its usefulness in establishing prognosis and informing treatment decision making, it is expected that frailty screening and assessment will continue to gain popularity as part of the pretreatment evaluation of older patients with cancer.

Association between Sarcopenia and Survival in Patients Undergoing Gamma Knife Surgery for Brain Metastasis from Breast Cancer: A Retrospective Single-centre Cohort Study

AIMS

Many recent studies related to cancer surgery have reported that sarcopenia influences mortality in surgical patients. However, few comprehensive studies have examined the associations between sarcopenia and short- and long-term surgical outcomes of metastatic cancer, especially breast cancer with brain metastasis. In the present study, we investigated the association between sarcopenia and mortality in patients who underwent gamma knife radiosurgery (GKRS) for brain metastasis with breast cancer.

MATERIALS AND METHODS

This retrospective study analysed 157 patients who underwent GKRS for brain metastasis with breast cancer between January 2014 and December 2018. A Cox regression analysis was carried out to evaluate the association between sarcopenia and mortality at 90 days, 180 days, 1 year, 3 years and the overall period.

RESULTS

In the Cox regression analysis, sarcopenia was significantly associated with high 90-day mortality (adjusted hazard ratio 3.46, 95% confidence interval 1.24-9.67, P = 0.018), 180-day mortality (adjusted hazard ratio 2.67, 95% confidence interval 1.37-5.22, P = 0.004), 1-year mortality (adjusted hazard ratio 2.39, 95% confidence interval 1.42-4.02, P = 0.001), 3-year mortality (adjusted hazard ratio 2.39, 95% confidence interval 1.53-3.74, P < 0.001) and overall mortality (adjusted hazard ratio 2.11, 95% confidence interval 1.37-3.26, P < 0.001).

CONCLUSION

Sarcopenia could be a risk factor for short- and long-term mortality in patients undergoing GKRS for brain metastasis from breast cancer.

Prevalence and Impact of Frailty in Pancreatic Cancer: A Systematic Review and Meta-Analysis Based on 35,191 Patients

BACKGROUND

Frailty has been associated with increased mortality among patients with pancreatic cancer. Nevertheless, several lines of evidence regarding the prevalence of frailty in patients with pancreatic cancer and mortality in patients with pancreatic cancer and frailty have not been thoroughly investigated and require clarification.

METHODS

A systematic review and meta-analysis of studies indexed in PubMed, Scopus, Web of Science, and Embase through March 2023 were conducted, and the pooled prevalence and relative risk (RR) estimate were calculated.

RESULTS

A total of 18 studies containing 35,191 patients with pancreatic cancer were included. The prevalence of frailty in pancreatic cancer was 45% (95% CI = 29-62; I2 = 99.9%; p = 0.000). In patients with pancreatic cancer, frailty was associated with increased relative risk for mortality (RR = 1.70; 95% CI = 1.30-2.22; I2 = 84.8%, p = 0.000).

CONCLUSIONS

Frailty prevalence in pancreatic cancer is common and exerts a significant negative impact on the survival of patients with pancreatic cancer. Our findings are characterized by significant heterogeneity, and caution is warranted in their interpretation. However, these findings highlight the importance of evaluating frailty, which may provide prognostic data and inform decision-making priorities.

Preoperative frailty as a predictive factor for postoperative complications in patients with pancreatic cancer

Frailty is considered one of the most important indicators of a patient's general condition. However, only a few studies have investigated the association between preoperative frailty and postoperative complications in pancreatic cancer. Therefore, this study aimed to examine this association in patients with pancreatic cancer. We retrospectively reviewed 52 consecutive patients who underwent pancreatectomy for pancreatic cancer between July 2019 and March 2021. Patients were classified into two groups according to the presence of postoperative complications. Their characteristics and clinical parameters, including physical function, were analyzed. Patients with postoperative complications had a higher prevalence of frailty (58.8% vs 14.3%, p = 0.003) and a shorter 6-min walk distance (380 m vs 436 m, p = 0.020) than those without postoperative complications. Logistic regression analysis identified preoperative frailty as the only independent risk factor for complications after pancreatectomy (p = 0.002). Preoperative frailty is associated with postoperative complications of pancreatectomy. Since preoperative frailty can be easily evaluated, it is a useful predictor of postoperative complications after pancreatectomy.

Hospital frailty risk score predicts worse outcomes in patients with chronic pancreatitis

Background

Chronic pancreatitis (CP) is a pathological fibroinflammatory response to persistent inflammation or stress to the pancreas. The effect of frailty on outcomes in patients with CP has not been previously examined. In this study, we examined the effect of frailty on outcomes in hospitalized patients with CP.

Methods

Records of patients with a primary or secondary discharge diagnosis of CP (ICD10-CM codes K86.0, K86.1) between January 2016 and December 2019 were obtained from the National Inpatient Sample database. Data were collected on patient demographics, hospital characteristics, comorbidities, and etiology of CP. The relationship between frailty and outcomes, including mortality, intensive care unit (ICU) admission, sepsis, shock, length of stay (LOS), and total hospitalization charges (THC), were analyzed using multivariate analysis.

Results

722,160 patients were included in the analysis. Patients with a high hospital frailty risk score had a higher mortality risk (adjusted odds ratio [aOR] 12.57, 95% confidence interval [CI] 10.42-15.16; P<0.001) compared to patients with low frailty scores. Patients with high frailty scores also had a higher risk of sepsis (aOR 5.75, 95%CI 4.97-6.66; P<0.001), shock (aOR- 26.25, 95%CI-22.83-30.19; P<0.001), ICU admission (aOR 25.86, 95% CI-22.58-29.62; P<0.001), and acute kidney injury (aOR 24.4, 95%CI 22.39-26.66; P<0.001). They also had a longer LOS (7.04 days, 95%CI 6.57-7.52; P<0.001) and higher THC ($72,200, 95%CI 65,904.52-78,496.66; P<0.001).

Conclusions

Frail patients, as determined by their hospital frailty risk score, are at high risk of worse outcomes. This data suggests opportunities for physicians to risk-stratify patients and predict outcomes.

Usefulness of frailty to predict short- and long-term outcomes in patients who have undergone major hepatectomy for perihilar cholangiocarcinoma

Aim

The influence of frailty on outcomes after hepatectomy for perihilar cholangiocarcinoma (PHCC) remains unclear. This study aimed to investigate the impact of frailty on the incidence of postoperative complications and survival after major hepatectomy for PHCC.

Methods

A total of 87 patients who had undergone surgery for PHCC between 2007 and 2020 were enrolled in this study. Frailty was scored retrospectively using the Clinical Frailty Scale (CFS). The survival and incidence of postoperative complications were compared based on the degree of frailty, and their risk factors were analyzed.

Results

The overall survival of the CFS score 1-2 group was significantly higher than that of the CFS score 3-7 group (P = .01). The survival benefit was especially observed in stage I or II PHCC. Furthermore, there were significant differences between the CFS score 1-3 group and the CFS score 4-7 group in the incidence of Clavien-Dindo classification grade ≥ IIIa (39.4% vs 70.6%; P = .03). Frailty was an independent risk factor for severe postoperative complications (odds ratio, 4.11; 95% confidence interval, 1.18-15.20; P = .03) and the incidence of systemic complications (P < .01).

Conclusion

Frailty is a predictive factor for short- and long-term outcomes in patients who have undergone major hepatectomy for PHCC.

Effects of body mass index and serum albumin on overall survival in patients with cancer undergoing pancreaticoduodenectomy: a single-center retrospective cohort study

Objectives

We aimed to explore whether body mass index (BMI) and albumin were associated with overall survival (OS) in individuals who underwent pancreaticoduodenectomy (PD) for cancer.

Methods

Three-hundred twenty-nine consecutive patients who underwent PD for cancer were enrolled from January 2020 to December 2020. All clinicopathological information was extracted based on medical records. The survival follow-ups were regularly performed and ended on June 30, 2021. The Kaplan-Meier survival analysis and univariate and multivariate Cox proportional-hazards models were used to assess the association of BMI and albumin with OS.

Results

Of the 329 patients, 186 (56.5%) were male, and median age at admission was 65.0 (56.0–71.0) years. There were 258 patients (78.4%) with BMI < 25.0 kg/m² and 89 patients (27.05%) with albumin < 35.0 g/L respectively. In overall cohort, BMI < 25.0 kg/m² was associated with OS (adjusted HR = 3.516, 95% CI = 1.076–11.492, P = 0.037). In contrast, albumin < 35.0 g/L did not affect OS. Subgroup analysis showed, in patients with pancreas lesion, BMI < 25.0 kg/m² had a higher risk for OS compared to BMI ≥ 25.0 kg/m² (adjusted HR = 3.209, 95% CI = 0.985–10.451, P = 0.048), while albumin < 35.0 g/L was not linked to OS. In patients with lesion in ampulla of Vater, duodenum, or common bile duct, there was no significant association of BMI and albumin with OS.

Conclusions

BMI, rather than serum albumin, was associated with OS in patients who underwent PD for cancer.

The impact of upper gastrointestinal surgical volume on short term pancreaticoduodenectomy outcomes for pancreatic adenocarcinoma in the SEER-Medicare population

BACKGROUND

Patients undergoing pancreaticoduodenectomy (PD) at low volume PD hospitals with high volume for other complex operations have comparable outcomes to high volume PD centers. We evaluated the impact of upper gastrointestinal operations (UGI) hospital volume on the outcomes of elderly, high risk patients undergoing PD.

METHODS

Patients >65 years old who underwent PD for pancreatic adenocarcinoma were identified from SEER-Medicare (2008-2015). Four volume cohorts were created using PD tertiles and UGI median: low (1st tertile PD), mixed-low (2nd tertile PD, low UGI), mixed-high (2nd tertile PD, high UGI) and high (3rd tertile PD). Multivariable logistic and negative binomial regression assessed short-term complications.

RESULTS

In total, 2717 patients were identified with a median age of 74.5 years. Patients treated at low, mixed-low and mixed-high volume hospitals, versus high volume, had higher risk of short-term complications, including major complications (low: OR 1.441, 95%CI 1.165-1.783; mixed-low: OR 1.374, 95%CI 1.085-1.740; mixed-high: OR 1.418, 95%CI 1.098-1.832) and 90-day mortality (low: OR 2.16, 95%CI 1.454-3.209; mixed-low: OR 2.068, 95%CI 1.347-3.175; mixed-high: OR 1.96, 95%CI 1.245-3.086).

CONCLUSION

Patients with pancreatic adenocarcinoma who are older and more medically complex benefit from undergoing surgery at high volume PD centers, independent of the operative experience of that center.

Three decades of change in pancreatoduodenectomy and future prediction of pathological and operative complexity

Despite increasing complexity of surgery and patient age, the duration of hospital stay and mortality rate after pancreatoduodenectomy are decreasing. Understanding changes over time permits an estimation of a future surgical cohort in which complexity will increase. It is important that surgeons continue to push boundaries.

Evaluation of frailty and neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios relationship in elderly people

It was aimed to evaluate the relationship between frailty and inflammation in people receiving home health care. It was a cross-sectional study. Edmonton Frail Scale was used to determine the level of frailty and, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were used to determine inflammation. Of 332 people included in the study, 54.82% were females and 45.18% were males. Participants' ages were between 65 and 106. When we examined the frailty of the participants according to the Edmonton Frail Scale, the mean score was 9.403 ± 2.032. The mean neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio of the participants were 4,397±5,038 and 169,363±101,461 respectively. Accordingly, neutrophil-to-lymphocyte ratio was high in men, frail elderly, 75-84 age range, hypertension patients, malnutrition patients; and neutrophil-to-lymphocyte ratio was low in diabetes mellitus, dementia, cerebrovascular accident and hemiplegia. Platelet-to-lymphocyte ratio, another inflammatory marker, was high in men, non-frail elderly, 75-84 age range, hypertension patients and cerebrovascular accident patients; it was low in hemiplegia, malnutrition, dementia, diabetes mellitus. In the study, no statistically significant difference was found between Edmonton Frail Scale and inflammatory markers. More studies are needed on this subject. In addition, we think that examining NLR and PLR values will be useful for monitoring inflammation in frail elderly.

Short-term outcomes after pancreatoduodenectomy in octogenarians: multicentre case-control study

BACKGROUND

Pancreatoduodenectomy (PD) is frequently the surgical treatment indicated for a number of pathologies. Elderly patients may be denied surgery because of concerns over poor perioperative outcomes. The aim of this study was to evaluate postoperative clinical outcomes and provide evidence on current UK practice in the elderly population after PD.

METHODS

This was a multicentre retrospective case-control study of octogenarians undergoing PD between January 2008 and December 2017, matched with younger controls from seven specialist centres in the UK. The primary endpoint was 90-day mortality. Secondary endpoints were index admission mortality, postoperative complications, and 30-day readmission rates.

RESULTS

In total, 235 octogenarians (median age 81 (range 80-90) years) and 235 controls (age 67 (31-79) years) were included in the study. Eastern Cooperative Oncology Group performance status (median 0 (range 0-3) versus 0 (0-2); P = 0.010) and Charlson Co-morbidity Index score (7 (6-11) versus 5 (2-9); P = 0.001) were higher for octogenarians than controls. Postoperative complication and 30-day readmission rates were comparable. The 90-day mortality rate was higher among octogenarians (9 versus 3 per cent; P = 0.030). Index admission mortality rates were comparable (4 versus 2 per cent; P = 0.160), indicating that the difference in mortality was related to deaths after hospital discharge. Despite the higher 90-day mortality rate in the octogenarian population, multivariable Cox regression analysis did not identify age as an independent predictor of postoperative mortality.

CONCLUSION

Despite careful patient selection and comparable index admission mortality, 90-day and, particularly, out-of-hospital mortality rates were higher in octogenarians.

Establishment of risk prediction model of postoperative pancreatic fistula after pancreatoduodenectomy: 2016 edition of definition and grading system of pancreatic fistula: a single center experience with 223 cases

Objective

To establish a risk prediction model for pancreatic fistula according to the pancreatic fistula standards of the 2016 edition.

Methods

Clinical data from 223 patients with PD admitted to Tianjin Third Central Hospital from January 2016 to December 2020 were retrospectively analyzed. Patients were divided into modeling (January 2016 to December 2018) and validation (January 2019 to December 2020) sets according to the time of admission. The risk factors for postoperative pancreatic fistula (POPF) were screened by univariate and multivariate logistic regression analyses, and a risk prediction model for POPF was established in the modeling set. This score was tested in the validation set.

Results

Logistic regression analysis showed that the main pancreatic duct index and CT value were independent risk factors according to the 2016 pancreatic fistula grading standard, based on which a risk prediction model for POPF was established. Receiver operating characteristic curve analysis showed that the area under the curve was 0.775 in the modeling set and 0.848 in the validation set.

Conclusion

The main pancreatic duct index and CT value of the pancreas are closely related to the occurrence of pancreatic fistula after PD, and the established risk prediction model for pancreatic fistula has good prediction accuracy.

Pancreatic outflow tract reconstruction after pancreaticoduodenectomy: a meta-analysis of randomized controlled trials

Background

To evaluate the outcomes of pancreaticogastrostomy and pancreaticojejunostomy after pancreatoduodenectomy with the help of a meta-analysis.

Methods

Randomized controlled trials comparing pancreaticogastrostomy and pancreaticojejunostomy were searched electronically using PubMed, The Cochrane Library, and EMBASE. Fixed and random-effects were used to measure pooled estimates. Research indicators included pancreatic fistula, delayed gastric emptying, postoperative hemorrhage, intraperitoneal fluid collection, wound infection, overall postoperative complications, reoperation, and mortality.

Results

Overall, 10 randomized controlled trials were included in this meta-analysis, with a total of 1629 patients. The overall incidences of pancreatic fistula and intra-abdominal collections were lower in the pancreaticogastrostomy group than in the pancreaticojejunostomy group (OR=0.73, 95% CI 0.55~0.96, p=0.02; OR=0.59, 95% CI 0.37~0.96, p=0.02, respectively). The incidence of B/C grade pancreatic fistula in the pancreaticogastrostomy group was lower than that in the pancreaticojejunostomy group, but no significant difference was observed (OR=0.61, 95%CI 0.34~1.09, p=0.09). Postoperative hemorrhage was more frequent in the pancreaticogastrostomy group than in the pancreaticojejunostomy group (OR=1.52; 95% CI 1.08~2.14, p=0.02). No significant differences in terms of delayed gastric emptying, wound infection, reoperation, overall postoperative complications, mortality, exocrine function, and hospital readmission were observed between groups.

Conclusion

This meta-analysis suggests that pancreaticogastrostomy reduces the incidence of postoperative pancreatic fistula and intraperitoneal fluid collection but increases the risk of postoperative hemorrhage compared with pancreaticojejunostomy.

Impact of Sarcopenia on Acute Kidney Injury after Infrarenal Abdominal Aortic Aneurysm Surgery: A Propensity Matching Analysis

Background: Sarcopenia contributes to increased morbidity and mortality in patients undergoing surgery for abdominal aortic aneurysms (AAA). However, few reports have demonstrated whether sarcopenia would affect the development of postoperative acute kidney injury (AKI) in these patients. This study aimed to examine whether sarcopenia is associated with AKI and morbidity and mortality after infrarenal AAA operation. Methods: We retrospectively analysed 379 patients who underwent infrarenal AAA surgery. The diagnosis of sarcopenia was performed using the skeletal muscle index, which was calculated from axial computed tomography at the level of L3. The patients were separated into those with sarcopenia (n = 104) and those without sarcopenia (n = 275). We applied multivariable and Cox regression analyses to evaluate the risk factors for AKI and overall mortality. A propensity score matching (PSM) evaluation was done to assess the postoperative results. Results: The incidence of AKI was greater in sarcopenia than non-sarcopenia group before (34.6% vs. 15.3%; p < 0.001) and after the PSM analysis (34.6% vs. 15.4%; p = 0.002). Multivariable analysis revealed sarcopenia to be associated with AKI before (p = 0.010) and after PSM (p = 0.016). Sarcopenia was also associated with overall mortality before (p = 0.048) and after PSM (p = 0.032). A Kaplan–Meier analysis revealed that overall mortality was elevated patients with sarcopenia before and after PSM than in those without (log-rank test, p < 0.001, p = 0.022). Conclusions: Sarcopenia was associated with increased postoperative AKI incidence and overall mortality among individuals who underwent infrarenal AAA operation.

Impact of skeletal muscle mass in patients with recurrent gastric cancer

BACKGROUND

We retrospectively examined the relationship among skeletal muscle mass index (SMI), prognosis, and chemotherapy side effects in patients with recurrent gastric cancer (RGC).

METHODS

Sixty-seven patients who developed recurrence after undergoing curative gastrectomy for gastric cancer at Tottori University Hospital and received palliative chemotherapy were included in this study. Pretreatment computed tomography was performed to measure the skeletal muscle mass (SMM) and cross-sectional SMM at the third lumbar vertebra. We focused on haematologic toxicity (neutropenia, thrombocytopenia, and anaemia), febrile neutropenia, and gastrointestinal toxicity (diarrhoea, vomiting, and stomatitis) as the side effects of chemotherapy.

RESULTS

Median SMIs for males and females (43.9 and 34.7 cm²/m², respectively) were used as cutoff values. The patients were classified into high (SMI^High; n = 34) and low SMI groups (SMI^Low; n = 33). The SMI^Low group included more patients treated with monotherapy (P = 0.016) compared with the SMI^High group, had a significantly lower number of chemotherapy lines (P = 0.049), and had a significantly higher incidence of grade 3 or 4 side effects (P = 0.010). The median survival rate was significantly higher in the SMI^High group (17.8 vs 15.8 months; P = 0.034). In the univariate analysis, body mass index, SMI, histological type, and prognostic nutritional index were identified as prognostic indicators. The multivariate analysis identified SMI (P = 0.037) and histological type (P = 0.028) as independent prognostic factors.

CONCLUSION

The incidence of grade 3 or 4 side effects was significantly higher in patients with SMI^Low RGC. SMI was a useful prognostic marker of RGC.

Preoperative plasma D-dimer independently predicts survival in patients with pancreatic ductal adenocarcinoma undergoing radical resection

Background

Elevated plasma D-dimer levels have been reported as an unfavorable prognostic indicator in many solid tumors. However, there are limited relevant studies in pancreatic cancer patients following radical surgery, and the clinical significance remains controversial. The aim of this study was to investigate the clinical and prognostic significance of preoperative plasma D-dimer in patients with pancreatic ductal adenocarcinoma (PDAC) undergoing resection.

Methods

A retrospective analysis was performed on all patients who consecutively underwent radical surgery for PDAC by laparotomy or robotic surgery from December 2011 to December 2018. Baseline clinicopathologic characteristics, preoperative laboratory parameters, and follow-up information were collected. Univariate and multivariate analyses were performed to analyze the prognostic value of preoperative plasma D-dimer.

Results

Among 1351 patients, elevated preoperative plasma D-dimer levels (≥ 0.55 ng/mL) were found in 417 (30.9%) patients. Three hundred twelve (23.09%) underwent minimally invasive robotic pancreatectomy. The median overall survival (OS) of patients with elevated D-dimer levels was 6.3 months shorter than that of patients with normal D-dimer levels (15.0 months vs 21.3 months, p < 0.001). Multivariate analysis showed that elevated D-dimer levels independently predicted poorer OS (hazard ratio, 1.33; 95% confidence interval, 1.17-1.51, p < 0.001). Subgroup analysis demonstrated that D-dimer was a reliable prognostic factor in patients who underwent R0 resection. In addition, integration of D-dimer, carbohydrate antigen 19-9 (CA19-9), and NLR provided a better prognostic model for PDAC patients before operation.

Conclusion

An elevated preoperative plasma D-dimer level was a reliable independent prognostic factor for OS in patients with PDAC undergoing resection. Combination of D-dimer, CA19-9, and NLR can enhance the prognostic accuracy before operation.

Robotic versus open pancreaticoduodenectomy: Is there any difference for frail patients?

BACKGROUND

Old age and frailty are predictors of early postoperative results after pancreatic surgery. We analysed the results of robotic and open pancreatoduodenectomy in elderly and frail patients.

METHODS

Data from the local robotic pancreatoduodenectomy database were reviewed and matched with those from open operations during the same period (2014-2020). Both old age and frailty were used to determine any correlation with postoperative outcomes. Elderly patients were defined as patients aged 70 years or more, while frailty was classified according to the validated modified Frailty Index.

RESULTS

A total of 118 pancreatoduodenectomies were included in the analysis: 65 (55.1%) robotic and 53 (44.9%) open. More than 50% of patients were frail. Overall, 7.6% of patients experienced grade IV Clavien-Dindo complications, and 3.4% died within 90 days after surgery. Frail patients experienced a similar rate of severe complications after robotic vs. open operations (5.3 vs. 11.6; p = 0.439) but earlier refeeding (3 days vs. 4 days; p = 0.006) and earlier drain removal (6 days vs. 7 days; p = 0.046) when operated on by a robotic approach. The oncological outcomes, including limphnodes retrieval, residual disease, recurrences, and survival, were not influenced by the surgical approach. Non-elderly patients also showed more benefits with the robotic approach (lower complication index, earlier refeeding, and drain removal).

CONCLUSIONS

Robotic pancreatoduodenectomy is associated with risks of major complications that are comparable to those of open operation in frail patients. Some perioperative parameters (refeeding, drain removal) seem to favour robotics in frail patients and younger patients, although at the price of longer operating times.
