The management of complicated colorectal cancer in older patients in a global perspective after COVID-19: the CO-OLDER WSES project

BACKGROUND

Colorectal (CRC) cancer is becoming a disease of the elderly. Ageing is the most significant risk factor for presenting CRC. Early diagnosis of CRC and management is the best way in achieving good outcomes and longer survival but patients aged ≥75 years are usually not screened for CRC. This group of patients is often required to be managed when they are symptomatic in the emergency setting with high morbidity and mortality rates. Our main aim is to provide clinical data about the management of elderly patients presenting complicated colorectal cancer who required emergency surgical management to improve their care.

METHODS

The management of complicated COlorectal cancer in OLDER patients (CO-OLDER; ClinicalTrials.gov ID: NCT05788224; evaluated by the local ethical committee CPP EST III-France with the national number 2023-A01094-41) in the emergency setting project provides carrying out an observational multicenter international cohort study aimed to collect data about patients aged ≥75 years to assess modifiable risk factors for negative outcomes and mortality correlated to the emergency surgical management of this group of patients at risk admitted with a complicated (obstructed and perforated) CRC. The CO-OLDER protocol was approved by Institutional Review Board and released. Each CO-OLDER collaborator is asked to enroll ≥25 patients over a study period from 1st January 2018 to 30th October 2023. Data will be analyzed comparing two periods of study: before and after the COVID-19 pandemic. A sample size of 240 prospectively enrolled patients with obstructed colorectal cancer in a 5-month period was calculated. The secured database for entering anonymized data will be available for the period necessary to achieve the highest possible participation.

RESULTS

One hundred eighty hospitals asked to be a CO-OLDER collaborator, with 36 potentially involved countries over the world.

CONCLUSIONS

The CO-OLDER project aims to improve the management of elderly people presenting with a complicated colorectal cancer in the emergency setting. Our observational global study can provide valuable data on the effectiveness of different management strategies in improving primary assessment, management and outcomes for elderly patients with obstructed or perforated colorectal cancer in the emergency setting, guiding clinical decision-making. This information can help healthcare providers make informed decisions about the best course of action for these patients.

Comparison of Safety and Efficacy between Laparoscopic Ventral Rectopexy and Delorme's Procedure for External Rectal Prolapse in Nonagenarians

Objectives

This study evaluates the safety and efficacy of laparoscopic ventral rectopexy (LVR) in nonagenarian patients with external rectal prolapse (ERP) compared to Delorme's procedure.

Methods

We conducted a retrospective analysis of prospectively collected data, including nonagenarian patients who underwent either LVR or Delorme's procedure, comparing outcomes such as morbidity, length of hospital stay (LOS), and recurrence rates.

Results

Between September 2009 and August 2023, 22 patients (median age 91, range 90-94 years) underwent LVR, while 12 patients (median age 91, range 90-96 years) received Delorme's procedure. Baseline characteristics, including sex ratio, parity, American Society of Anesthesiology grade, and Body Mass Index, did not significantly differ between the groups. LVR had a significantly longer operating time but lower blood loss than Delorme's procedure. Postoperative LOS was significantly shorter for LVR patients (median 1, range 1-3 days) compared to Delorme's procedure patients (median 2.5, range 1-13 days; P = 0.001). Notably, no significant morbidity occurred in the LVR group, while one case of delirium and another of solitary rectal ulcer syndrome were observed in the Delorme's procedure group. Recurrence rates were lower in the LVR group, with no recurrences during a median follow-up of 23 months (range 1-65 months), compared to one recurrence at 2 months during a median follow-up of 34 months (range 1-96 months) in the Delorme's procedure group.

Conclusions

LVR is a safe and effective surgical option for nonagenarian ERP patients, showing favorable outcomes in terms of morbidity, LOS, and recurrence rates compared to Delorme's procedure.

Application of MFI-5 in severe complications and unfavorable outcomes after radical resection of colorectal cancer

BACKGROUND

Frailty is considered a characteristic manifestation of physiological decline in multiple organ systems, which significantly increases the vulnerability of elderly individuals with colorectal cancer (CRC) and is associated with a poor prognosis. While studies have demonstrated that the 11-factor Modified Frailty Index (mFI-11) can effectively predict adverse outcomes following radical resection of CRC, there is a lack of research on the applicability of the 5-factor Modified Frailty Index (mFI-5) within this patient population.

METHODS

In this retrospective analysis, we examined a cohort of CRC patients aged 65 years and above who had undergone radical resection. For each patient, we calculated their mFI-5 score, considering a score of ≥ 2 as an indication of frailty. We conducted univariate and multivariate analyses to assess the association between the mFI-5 and adverse outcomes as well as postoperative complications.

RESULTS

Patients with an mFI-5 score ≥ 2 exhibited a significantly higher incidence of serious postoperative complications (53% vs. 30%; P = 0.001) and experienced a longer hospital stay [19.00 (15.00-24.50) vs. 17.00 (14.00-20.00); P < 0.05]. Notably, an mFI-5 score greater than 2 emerged as an independent risk factor for severe postoperative complications (odds ratio: 2.297; 95% confidence interval: 1.216 to 4.339; P = 0.01). Furthermore, the mFI-5 score displayed predictive capabilities for severe postoperative complications with an area under the receiver operating characteristic (ROC) curve of 0.629 (95% confidence interval: 0.551 to 0.707; P < 0.05).

CONCLUSION

The mFI-5 demonstrates a high level of sensitivity in predicting serious complications, prolonged hospital stays, and mortality following radical resection of colorectal carcinoma. As a practical clinical assessment tool, the mFI-5 enables the identification of high-risk patients and facilitates preoperative optimization.

Elderly patients over 80 years undergoing colorectal cancer resection: Development and validation of a predictive nomogram for survival

BACKGROUND

Surgery remains the primary treatment for localized colorectal cancer (CRC). Improving surgical decision-making for elderly CRC patients necessitates an accurate predictive tool.

AIM

To build a nomogram to predict the overall survival of elderly patients over 80 years undergoing CRC resection.

METHODS

Two hundred and ninety-five elderly CRC patients over 80 years undergoing surgery at Singapore General Hospital between 2018 and 2021 were identified from the American College of Surgeons – National Surgical Quality Improvement Program (ACS-NSQIP) database. Prognostic variables were selected using univariate Cox regression, and clinical feature selection was performed by the least absolute shrinkage and selection operator regression. A nomogram for 1- and 3-year overall survival was constructed based on 60% of the study cohort and tested on the remaining 40%. The performance of the nomogram was evaluated using the concordance index (C-index), area under the receiver operating characteristic curve (AUC), and calibration plots. Risk groups were stratified using the total risk points derived from the nomogram and the optimal cut-off point. Survival curves were compared between the high- and low-risk groups.

RESULTS

Eight predictors: Age, Charlson comorbidity index, body mass index, serum albumin level, distant metastasis, emergency surgery, postoperative pneumonia, and postoperative myocardial infarction, were included in the nomogram. The AUC values for the 1-year survival were 0.843 and 0.826 for the training and validation cohorts, respectively. The AUC values for the 3-year survival were 0.788 and 0.750 for the training and validation cohorts, respectively. C-index values of the training cohort (0.845) and validation cohort (0.793) suggested the excellent discriminative ability of the nomogram. Calibration curves demonstrated a good consistency between the predictions and actual observations of overall survival in both training and validation cohorts. A significant difference in overall survival was seen between elderly patients stratified into low- and high-risk groups (P < 0.001).

CONCLUSION

We constructed and validated a nomogram predicting 1- and 3-year survival probability in elderly patients over 80 years undergoing CRC resection, thereby facilitating holistic and informed decision-making among these patients.

Elective colorectal cancer surgery in nonagenarians and postoperative outcomes

OBJECTIVES

The population of very elderly patients is increasing, and nonagenarians have significantly higher mortality rates and poorer rates of survival than younger patients. Meanwhile, recent studies have shown colorectal cancer surgery in nonagenarian patients to be feasible regarding postoperative outcomes. This retrospective study aims to evaluate the postoperative outcomes of nonagenarians in the latest clinical settings.

METHODS

Consecutive nonagenarian patients who underwent elective colorectal cancer surgery between 2018 and 2020 retrospectively enrolled (Trial registration number: UMIN000046296 on December 7th, 2021). Clinicopathological data and short-term postoperative outcomes were collected for statistical analysis.

RESULTS

This study included 81 nonagenarian patients (31 males, 50 females). Postoperative complications occurred in 21 patients (25.9%), and 3 patients died within 90 days (3.7%). Multivariate analysis revealed prognostic nutritional index was a significant predictor of postoperative complications (OR 2.99, 95% CI 0.78-9.10, P = 0.048), and performance status ≥ 3 could be an independent risk factor of 90-day mortality (HR 32.30, 95% CI 3.20-326.10, P = 0.032).

CONCLUSIONS

Short-term outcomes after surgical treatment for nonagenarian patients with colorectal cancer were acceptable. Low prognostic nutritional index was closely related to postoperative complications and poor performance status could also lead to 90-day mortality. In aging populations, risk stratification to prevent poorer postoperative outcomes in nonagenarian patients is needed.

Immune Microenvironment in Sporadic Early-Onset versus Average-Onset Colorectal Cancer

The incidence of left-sided colon and rectal cancer in young people are increasing worldwide, but its causes are poorly understood. It is not clear if the tumor microenvironment is dependent on age of onset, and little is known about the composition of tumor-infiltrating T cells in early-onset colorectal cancer (EOCRC). To address this, we investigated T-cell subsets and performed gene expression immune profiling in sporadic EOCRC tumors and matched average-onset colorectal cancer (AOCRC) tumors. Left-sided colon and rectal tumors from 40 cases were analyzed; 20 EOCRC (<45 years) patients were matched 1:1 to AOCRC (70-75 years) patients by gender, tumor location, and stage. Cases with germline pathogenic variants, inflammatory bowel disease or neoadjuvant-treated tumors were excluded. For T cells in tumors and stroma, a multiplex immunofluorescence assay combined with digital image analysis and machine learning algorithms was used. Immunological mediators in the tumor microenvironment were assessed by NanoString gene expression profiling of mRNA. Immunofluorescence revealed no significant difference between EOCRC and AOCRC with regard to infiltration of total T cells, conventional CD4⁺ and CD8⁺ T cells, regulatory T cells, or γδ T cells. Most T cells were located in the stroma in both EOCRC and AOCRC. Immune profiling by gene expression revealed higher expression in AOCRC of the immunoregulatory cytokine IL-10, the inhibitory NK cell receptors KIR3DL3 and KLRB1 (CD161), and IFN-a7 (IFNA7). In contrast, the interferon-induced gene IFIT2 was more highly expressed in EOCRC. However, in a global analysis of 770 tumor immunity genes, no significant differences could be detected. T-cell infiltration and expression of inflammatory mediators are similar in EOCRC and AOCRC. This may indicate that the immune response to cancer in left colon and rectum is not related to age of onset and that EOCRC is likely not driven by immune response deficiency.

The Quality of Life of Patients with Surgically Treated Colorectal Cancer: A Narrative Review

INTRODUCTION

Quality of life is a topic increasingly being addressed by researchers. Due to the increasing incidence of colorectal cancer, this issue is particularly relevant. Despite the increasing number of publications on this topic each year, it still requires further research. The aim of this study was to analyze the available literature from the past 10 years, addressing the topic of QoL in patients with colorectal cancer which has been treated surgically.

MATERIAL AND METHODS

This review is based on 93 articles published between 2012 and 2022. It analyzes the impact of socioeconomic factors, the location and stage of the tumor, stoma and the method of surgical treatment on patients' QoL and sexual functioning.

RESULTS

CRC has a negative impact on patients' financial status, social functioning, pain and physical functioning. Patients with stage II or III cancer have an overall lower QoL than patients with stage I. The more proximally the lesion is located to the sphincters, the greater the negative impact on the QoL. There was a significant difference in favor of laparoscopic surgery compared with open surgery. In patients with a stoma, the QoL is lower compared with patients with preserved gastrointestinal tract continuity. The more time has passed since surgery, the more the presence of a stoma has a negative impact on QoL. Surgery for CRC negatively affects patients' sex lives, especially in younger people and among men.

CONCLUSIONS

This study may contribute to the identification of the factors that affect the QoL of patients with surgically treated colorectal cancer. This will allow even more effective and complete treatment, facilitating patients' return to normal physical, mental and social functioning.
