Charlson comorbidity index predicts anastomotic leakage in patients with resected right-sided colon cancer

Use of Electronic Health Records to Identify Factors Related to Skin Changes in Terminal Patients

OBJECTIVE

To investigate the incidence of skin changes at life's end (SCALE) among hospice patients and identify associated factors.

METHODS

The authors conducted a retrospective chart review of demographic data, medical history, Braden Scale assessment scores, Charlson Comorbidity Index, symptom records, and medical treatments of patients admitted to a local teaching hospital's hospice unit between May 2019 and April 2021.

RESULTS

Most (79%) of the 300 hospice patients included in the study had cancer. Of the 181 patients who died, 49 (60.3%) had SCALE. Logistic regression analysis revealed that greater variations in Braden Scale scores from admission to predeath (odds ratio, 1.188; 95% CI, 1.014-1.392; P = .033), higher Eastern Cooperative Oncology Group grades (odds ratio, 1.965; 95% CI, 1.241-3.109; P = .004), and elevated Charlson Comorbidity Index scores (odds ratio, 1.514; 95% CI, 1.237-1.854; P < .001) significantly increased the likelihood of developing SCALE.

CONCLUSIONS

The findings suggest that the occurrence of SCALE may serve as a valuable clinical indicator for healthcare professionals to recognize that a patient is approaching the end of life. Consequently, the care approach should prioritize pain relief and promote comfort rather than wound healing in this patient population. These results provide evidence to support the integration of SCALE-related training programs for hospice care, which can increase healthcare professionals' awareness and understanding of SCALE. Ultimately, the implementation of such training programs may lead to more appropriate care for hospice patients with SCALE, enhancing their quality of life at the end of life.

Long‐term prognostic outcomes in high‐risk T1 colorectal cancer: A multicentre retrospective comparison of surgery versus observation postendoscopic treatment

Aim

The risk of lymph node metastasis after endoscopic resection of high‐risk T1 colorectal cancer prompts additional resection. However, age and comorbidities are considered in decision‐making and some surgeons opt for observation. We compared the long‐term outcomes of these approaches with the aim of clarifying the need for additional resection.

Method

This multicentre retrospective study included high‐risk T1 colorectal cancer patients treated with endoscopic submucosal dissection (ESD) between January 2013 and April 2021. Patients who met one or more of the following criteria were eligible for inclusion: submucosal invasion depth ≥1000 μm, vessel invasion, poor differentiation, budding grade 2/3 or a positive vertical margin. Patients were divided into resection (R) and observation (O) groups. Outcomes were evaluated based on overall survival (OS) and 5‐year cancer‐specific survival (CSS), with an additional stratified analysis using the age‐adjusted Charlson comorbidity index (ACCI).

Results

The study included 178 patients (group R, n = 131; group O, n = 47). Patients in group O were significantly older and had more comorbidities. Group R showed better 5‐year OS and CSS (OS 87.0% vs. 58.9%, p = 0.001; CSS 98.8% vs. 78.4%, p = 0.002). Stratification by ACCI revealed that benefits of additional resection remained for patients with ACCI ≤ 6 (OS 91.2% vs. 58.3%, p = 0.013; CSS 98.4% vs. 61.7%, p < 0.001) but not for those with ACCI ≥7 (OS 75.9% vs. 59.8%, p = 0.289; CSS 100% vs. 100%, p = 0.617).

Conclusions

Significant survival benefits were demonstrated in group R patients with high‐risk T1 cancer. However, the survival benefit of additional surgical resection was unconfirmed in patients with ACCI ≥ 7.

Analysis of outcomes of penetrating colonic injuries managed with or without fecal diversion

Traumatic colorectal injuries can be managed by either fecal diversion or primary repair / resection and anastomosis. We aimed to study differences in outcomes in adult patients managed with or without fecal diversion at time of initial operation. The National Trauma Databank (NTDB) was used to identify adult patients (ages 18-64 years) with penetrating colonic injuries for the years 2013-2015. We included patients with Injury Severity Score (ISS) of 9-24 excluding patients with concomitant extra-abdominal Abbreviated Injury Scale (AIS) score of 3 or more. Subjects arriving without signs of life, expiring in ER or with missing data were excluded. Data was collected for age, gender, vital signs on presentation, discharge disposition and length of stay (LOS). Patients were divided into two groups based on whether or not fecal diversion was performed within 1 day of presentation. Primary outcome assessed was in-hospital mortality and unplanned return to OR. Secondary outcomes were acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), deep vein thrombosis (DVT), pulmonary embolism (PE), pneumonia, organ surgical site infection (SSI), deep SSI, severe sepsis and unplanned intubation. Statistical analysis was conducted using SPSS for windows. P-value < 0.05 was considered statistically significant. Of 2,598,467 patients, 5344 (0.21%) sustained a penetrating colonic injury. 2339 (43.8%) patients met criteria for age, ISS, AIS, signs of life and ED outcome. 173 patients underwent fecal diversion within 24 h of presentation (Group 1) while 708 did not (Group 2). Patients with missing data were excluded leaving 162 patients in Group 1 and 657 patients in Group 2. Groups 1 and 2 were noted to be similar in terms of ISS (median of 10 in both), age (median of 31 vs 29 years), percentage of male patients (85.2% vs 87.8%; p = 0.44), mean systolic blood pressure (127 mmHg vs 126 mmHg; p = 0.54), mean pulse rate (95.4 vs 94.5; p = 0.60) and mean respiratory rate (20.4 vs 20.1; p = 0.56) respectively. Median LOS was 10 days in both groups. No statistically significant differences were found between groups 1 and 2 in the primary outcomes of in-hospital mortality (2.4% vs 3.5%; OR: 1.43; 95% confidence interval (CI): 0.49-4.20) or unplanned return to OR (4.3% vs 7.8%; OR: 1.86; 95% CI: 0.83-4.19). No statistically significant differences were noted between groups 1 and 2 in the secondary outcomes of AKI (3.7% vs 3.8%; OR: 1.03; 95% CI 0.41-2.55), ARDS (1.2% VS 1.7%; OR: 1.36; 95% CI 0.30-6.21), DVT (1.9% vs 4.0%; OR: 2.18; 95% CI 0.65-7.31), PE (1.9% vs 2.0%; OR: 1.07; 95% CI 0.30-3.80), pneumonia (4.9% vs 5.3%; OR: 1.08; 95% CI 0.49-2.38), organ SSI (3.7% vs 7.0%; OR: 1.96; 95% CI: 0.82-4.67), deep SSI (3.7% vs 4.4%; OR: 1.20, 95% CI 0.49-2.94), severe sepsis (3.7% vs 3.3%; OR: 0.90; 95% CI: 0.36-2.26) or unplanned intubation (1.9% vs 1.7%; OR: 0.90; 95% CI 0.25-3.27). Adult patients with penetrating colonic injuries with ISS 9-24 in the absence of serious extra-abdominal injury who undergo surgery within 24 h of presentation do not seem to derive a statistically significant benefit from fecal diversion in terms of post-operative complications and mortality. In more severely injured patients fecal diversion may continue to provide a benefit.

Allostatic load as a predictor of postoperative complications in patients with breast cancer

Allostatic load (AL) is a biological measure of cumulative exposure to socioenvironmental stressors (e.g., poverty). This study aims to examine the association between allostatic load (AL) and postoperative complications (POC) among patients with breast cancer. Females ages 18+ with stage I-III breast cancer who received surgical management between 01/01/2012-12/31/2020 were identified in the Ohio State Cancer registry. The composite AL measure included biomarkers from the cardiovascular, metabolic, immune, and renal systems. High AL was defined as composite scores greater than the cohort's median (2.0). POC within 30 days of surgery were examined. Univariable and multivariable regression analysis examined the association between AL and POC. Among 4459 patients, 8.2% had POC. A higher percentage of patients with POC were unpartnered (POC 44.7% vs no POC 35.5%), government-insured (POC 48.2% vs no POC 38.3%) and had multiple comorbidities (POC 32% vs no POC 20%). Patients who developed POC were more likely to have undergone sentinel lymph node biopsy followed by axillary lymph node dissection (POC 51.2% vs no POC 44.6%). High AL was associated with 29% higher odds of POC (aOR 1.29, 95% CI 1.01-1.63). A one-point increase in AL was associated with 8% higher odds of POC (aOR 1.08, 95% CI 1.02-1.16) and a quartile increase in AL was associated with 13% increased odds of POC (aOR 1.13, 95% CI 1.01-1.26). Among patients undergoing breast cancer surgery, increased exposure to adverse socioenvironmental stressors, operationalized as AL, was associated with higher odds of postoperative complications.

Unplanned emergency department visits within 90 days of hip hemiarthroplasty for osteoporotic femoral neck fractures: Reasons, risks, and mortalities

Objectives

Bipolar hemiarthroplasty is commonly performed to treat displaced femoral neck fractures in osteoporotic patients. This study aimed to assess the occurrence and outcomes of unplanned return visits to the emergency department (ED) within 90 days following bipolar hemiarthroplasty for displaced femoral neck fractures.

Methods

The clinical data of 1322 consecutive patients who underwent bipolar hemiarthroplasty for osteoporotic femoral neck fractures at a tertiary medical center were analyzed. Data from the patients' electronic medical records, including demographic information, comorbidities, and operative details, were collected. The risk factors and mortality rates were analyzed.

Results

Within 90 days after surgery, 19.9% of patients returned to the ED. Surgery-related reasons accounted for 20.2% of the patient's returns. Older age, a high Charlson comorbidity index score, chronic kidney disease, and a history of cancer were identified as significant risk factors for unplanned ED visits. Patients with uncemented implants had a significantly greater risk of returning to the ED due to periprosthetic fractures than did those with cemented implants (P = 0.04). Patients who returned to the ED within 90 days had an almost fivefold greater 1-year mortality rate (15.2% vs 3.1%, P < 0.001) and a greater overall mortality rate (26.2% vs 10.5%, P < 0.001).

Conclusions

This study highlights the importance of identifying risk factors for unplanned ED visits after bipolar hemiarthroplasty, which may contribute to a better prognosis. Consideration should be given to the use of cemented implants for hemiarthroplasty, as uncemented implants are associated with a greater risk of periprosthetic fractures.

Allostatic Load as a Predictor of Postoperative Complications in Patients with Breast Cancer

BACKGROUND

Allostatic load (AL) is a biological measure of cumulative exposure to socioenvironmental stressors (e.g., poverty). This study aims to examine the association between allostatic load (AL) and postoperative complications (POC) among patients with breast cancer.

METHODS

Assigned females at birth ages 18 + with stage I-III breast cancer who received surgical management between 01/01/2012-12/31/2020 were identified in the Ohio State Cancer registry. The composite AL measure included biomarkers from the cardiovascular, metabolic, immune, and renal systems. High AL was defined as composite scores greater than the cohort's median (2.0). POC within 30 days of surgery were examined. Univariable and multivariable regression analysis examined the association between AL and POC.

RESULTS

Among 4,459 patients, 8.2% had POC. A higher percentage of patients with POC were unpartnered (POC 44.7% vs no POC 35.5%), government-insured (POC 48.2% vs no POC 38.3%) and had multiple comorbidities (POC 32% vs no POC 20%). Patients who developed POC were more likely to have undergone sentinel lymph node biopsy followed by axillary lymph node dissection (POC 51.2% vs no POC 44.6%). High AL was associated with 29% higher odds of POC (aOR 1.29, 95% CI 1.01-1.63). A one-point increase in AL was associated with 8% higher odds of POC (aOR 1.08, 95% CI 1.02-1.16) and a quartile increase in AL was associated with 13% increased odds of POC (aOR 1.13, 95% CI 1.01-1.26).

CONCLUSION

Among patients undergoing breast cancer surgery, increased exposure to adverse socioenvironmental stressors, operationalized as AL, was associated with higher odds of postoperative complications.

Elderly nasopharyngeal carcinoma patients (aged ≥70 years): Survival and treatment strategies

BACKGROUND

With the coming of the aging society, the incidence of elderly nasopharyngeal carcinoma (NPC) has been increasing which may result in considerable disease burden; however, the optimal treatment strategy for elderly patients is still debatable.

METHODS AND RESULTS

Clinical data on 294 elderly NPC patients aged ≥70 treated between 2009 and 2019 was analyzed. Kaplan-Meier method was used to estimate overall survival (OS) and cancer-specific survival (CSS) rates. With a median follow-up of 53.25 months, the 5-year estimated OS and CSS for the entire group were 59.5% and 69.8%, respectively. 146 patients died within the follow-up period, of which recurrence + metastasis (48%) and internal medical disease unrelated to NPC (32%) are the primary causes of death. On univariable analysis, (IMRT vs. 3D-CRT) (p = 0.001; p = 0.000), T stage (p = 0.001; p = 0.000), N stage (p = 0.013; p = 0.000) and clinical stage (p = 0.000; p = 0.000) were associated with OS and CSS; Charlson Comorbidity Index (CCI) (p = 0.016) was associated with OS. The addition of chemotherapy (CT) correlated with better CSS (p = 0.039), but did not improve OS (p = 0.056) for stage III-IV subgroup. On multivariate analysis, advanced clinical stage independently predicted poorer OS (p = 0.002) and CSS (p = 0.000). In addition, the application of IMRT was an independent protective factor on both OS (p = 0.028) and CSS (p = 0.030).

CONCLUSION

IMRT is a reasonable treatment strategy to improve survival for elderly NPC patients aged over 70 years; consideration of adding chemotherapy for elderly population should be weighed carefully.

A novel scoring system for the early detection of anastomotic leakage: bedside leak score-a pilot study

Background

Anastomotic leakage is a major complication in colorectal surgery, resulting in significant morbidity and mortality rates. Despite substantial progress in surgical technique, anastomotic leakage rates remain stable. An early diagnosis of anastomotic leaks was proven to reduce adverse outcomes and improve survival.

Objective

This study aims to find a novel scoring system for detecting anastomotic leaks using inflammatory and nutritional indicators after colorectal surgery. Our purpose was to analyze the diagnostic accuracy of leak scores ( ( CRP POD 3 ) ( CRP POD 1 ) ∗ preoperative albumin level ) in predicting postoperative complications.

Design

The study included colorectal cancer patients who underwent curative surgery at Koc University Hospital between 2014 and 2018. Patients were categorized into two groups depending on the presence of anastomotic leaks and compared in terms of preoperative albumin levels, CRP levels in postoperative days 1 and 3, anastomotic leakage rates, length of hospital stay, and CRP quotient, which was calculated by dividing POD 3 CRP level to POD 1 CRP level. The bedside leak score is calculated by dividing the CRP quotient by the preoperative albumin level. The predictive value of bedside leak score, CRP quotient, and preoperative albumin levels in estimating anastomotic leakage was analyzed, and a cutoff value for the leak score was calculated.

Results

A total of 184 patients were included in the study. The leak score, CRP POD 3-1 ratio, and preoperative albumin levels were found to successfully detect anastomotic leakage. The area under the curve for the leak score was calculated as 0.78. The optimal cutoff value was found to be 50.3 for the bedside leak score, which shows 90.9% sensitivity and 59.3% specificity.

Conclusion

The leak score may represent a valuable diagnostic tool for detecting patients at risk for anastomotic leakage after colorectal surgery and planning a better strategy to reduce morbidity and mortality rates and associated costs. However, further multicenter studies with large cohorts are necessary to confirm these results.

Short-term outcomes of colorectal cancer surgery in patients with dialysis: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to evaluate the effect of dialysis-dependent chronic kidney disease (CKD) on postoperative complications in colorectal cancer surgery.

METHODS

In April 2023, we systematically searched PubMed, the Cochrane library, and Ovid for relevant studies on short-term outcomes of colorectal cancer surgery in patients with dialysis and analyzed the findings from these studies for meta-analysis.

RESULTS

Our systematic and meta-analysis review identified seven studies involving 50713 patients. We showed that the dialysis group had higher rates of mortality (OR = 4.12, 95%CI: 2.75-6.20, P < 0.001), cardiac complications (OR = 2.45, 95%CI: 1.88-3.21, P < 0.001), and pneumonia (OR = 2.68, 95%CI: 1.83-3.93, P < 0.001). On the other hand, there were no differences in superficial/deep surgical site infection (SSI) (odds ratio [OR] = 1.17, 95%CI: 0.90-1.53, P = 0.230) and organ/space SSI (OR = 1.35, 95%CI: 1.00-1.82, P = 0.053) between the dialysis group and non-dialysis group.

CONCLUSION

Our meta-analysis showed that dialysis-dependent CKD was associated with higher rates of mortality, cardiac complications, and pneumonia after colorectal cancer surgery. However, the limitations of this meta-analysis should be taken into consideration when interpreting the results.

Anastomotic leak risk factors following colon cancer resection: a systematic review and meta-analysis

BACKGROUND

Despite improved surgical techniques, anastomotic leakage is still a serious complication that can occur after colon cancer resection, resulting in increased morbidity and mortality. The aim of this study was to evaluate the risk factors for anastomotic leakage after colon cancer surgery, provide a theoretical basis for reducing its occurrence, and guide the practice of clinicians.

METHODS

A systematic review of PubMed, Ovid, Web of Science and Cochrane Central Register of Controlled Trials databases was conducted by using a combination of subject terms and free words for online searches. The databases were searched from their inception to 31 March 2022, and all cross-sectional, cohort or case‒control studies examining the risk factors for the development of anastomotic fistula after surgery for colon cancer were identified.

RESULT

A total of 2133 articles were searched for this study, and 16 publications were ultimately included, all of which were cohort studies. A total of 115,462 subjects were included, and a total of 3959 cases of anastomotic leakage occurred postoperatively, with an incidence of 3.4%. The odds ratio (OR) and 95% confidence interval (CI) were used for evaluation. Male sex (OR = 1.37, 95% CI: 1.29-1.46, P < 0.00001), BMI (OR = 1.04, 95% CI: 1.00-1.08, P = 0.03), diabetes (OR = 2.80, 95% CI: 1.81-4.33, P < 0.00001), combined lung disease (OR = 1.28, 95% CI: 1.15-1.42, P < 0.00001), anaesthesia ASA score (OR = 1.35, 95% CI: 1.24-1.46, P < 0.00001), ASA class ≥ III (OR = 1.34, 95% CI: 1.22-1.47, P < 0.00001), emergency surgery (OR = 1.31, 95% CI: 1.11-1.55, P = 0.001), open surgery (OR = 1.94, 95% CI: 1.69-2.24, P < 0.00001) and type of surgical resection (OR = 1.34, 95% CI: 1.12-1.61, P = 0.002) are risk factors for anastomotic leakage after colon cancer surgery. There is still a lack of strong evidence on whether age (OR = 1.00, 95% CI: 0.99-1.01, P = 0.36) and cardiovascular disease (OR = 1.18, 95% CI: 0.94-1.47, P = 0.16) are factors influencing the occurrence of anastomotic leakage after colon cancer surgery.

CONCLUSIONS

Male sex, BMI, obesity, coexisting pulmonary disease, anaesthesia ASA score, emergency surgery, open surgery and type of resection were risk factors for anastomotic leakage after colon cancer surgery. The effect of age and cardiovascular disease on postoperative anastomotic leakage in patients with colon cancer needs further study.

Risk Factors for Severe Postoperative Complications after Oncologic Right Colectomy: Unicenter Analysis

Background and Objectives: This study aimed to investigate the potential risk factors for severe postoperative complications after oncologic right colectomy. Materials and Methods: All consecutive patients with right colon cancer who underwent right colectomy in our department between 2016 and 2021 were retrospectively included in this study. The Clavien-Dindo grading system was used to evaluate postoperative complications. Univariate and multivariate logistic regression analyses were used to investigate risk factors for postoperative severe complications. Results: Of the 144 patients, there were 69 males and 75 females, with a median age of 69 (IQR 60-78). Postoperative morbidity and mortality rates were 41.7% (60 patients) and 11.1% (16 patients), respectively. The anastomotic leak rate was 5.3% (7 patients). Severe postoperative complications (Clavien-Dindo grades III-V) were present in 20 patients (13.9%). Univariate analysis showed the following as risk factors for postoperative severe complications: Charlson score, lack of mechanical bowel preparation, level of preoperative proteins, blood transfusions, and degree of urgency (elective/emergency right colectomy). In the logistic binary regression, the Charlson score (OR = 1.931, 95% CI = 1.077-3.463, p = 0.025) and preoperative protein level (OR = 0.049, 95% CI = 0.006-0.433, p = 0.007) were found to be independent risk factors for postoperative severe complications. Conclusions: Severe complications after oncologic right colectomy are associated with a low preoperative protein level and a higher Charlson comorbidity index.
