Late assessment of quality of life in patients with rectal carcinoma: comparison between sphincter preservation and definitive colostomy

Point/Counterpoint #2: Current Clinical Considerations With Nonoperative Management of Rectal Cancer

ABSTRACT

Locally advanced rectal cancer has historically been treated with multimodal therapy consisting of radiation therapy, chemotherapy, and total mesorectal excision. However, recent prospective trials and registry studies have demonstrated similar disease outcomes with nonoperative management for patients who experience an excellent clinical response to radiation and chemotherapy. This article reviews data regarding nonoperative management for rectal cancer, and highlights current challenges and limitations in a point-counterpoint format, in the context of two clinical cases.

Quality of life assessment for rectal cancer patients: A comparison between sphincter preservation and permanent colostomy

"This study aims to compare the quality of life in patients with rectal cancer between sphincter preservation and permanent colostomy. The present study is a cross-sectional study that was performed on 120 patients (60 cases in the sphincter maintenance group and 60 cases in the permanent colostomy group) who underwent surgery from February 2017 to November 2016. Quality of life assessment was provided with QLQ-C30 and QLQ-CR29 questionnaires. Finally, the collected data were analyzed using SPSS23 software. According to the results of the QLQ-C30 questionnaire, there was no statistically significant difference in patients' quality of life in terms of performance in the study groups (P˃0.05). Symptoms such as nausea, pain, shortness of breath, sleep disturbance, loss of appetite, constipation and economic problems in the study groups were not statistically significant (P˃0.05). But the mean symptoms of fatigue (P=0.038) and diarrhea (P=0.037) were significantly higher in the sphincter maintenance group than the permanent colostomy group. The mean score of patients' quality of life was 53.43 ± 8.40 in the sphincter retention group and 52.23 ± 11.45 in the permanent colostomy group (P = 0.556). According to the results, the quality of life in the two surgical methods of sphincter preservation and permanent colostomy was not statistically significant. Therefore, treatment decisions should be made by informing patients, both based on their preferences and the physician's clinical judgment."

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.

Health-related quality of life in advanced colorectal cancer patients in China: a nationwide hospital-based survey

Background

Colorectal cancer (CRC) is one of the most common cancers in China, and most CRC patients have already reached an advanced stage by the time of initial diagnosis. Due to the loss of health as a result of cancer, it has consequence on the treatment which may affect the psychophysical and social impairment of CRC patients. These indicators (psychophysical, function and social impairment) affect the health-related quality of life (HRQOL). There are limited studies that focus on advanced CRC patients in China. This study aimed to assess the HRQOL and its associated factors of advanced CRC patients in China.

Methods

This was a cross-sectional, nationwide, hospital-based, and multi-center survey. According to the traditional administrative district definition, we selected 19 hospitals in 7 regions by multi-stage stratified sampling in China. For each eligible CRC patient with stage III or IV in the selected hospitals, socio-demographics, clinical information, and HRQOL were collected based on patients’ self-reporting and/or medical records between March 2020 and March 2021. Patients completed the Functional Assessment of Cancer Therapy Colorectal (FACT-C) plus-traditional Chinese version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-9.

Results

A total of 4,589 CRC patients (mean age 60.1 years, including 2,730 males and 1,859 females) were included. The total score of HRQOL in population was 128.2±24.70. There were significant differences in the overall score of HRQOL in gender, education level, occupation, region, disease type, and disease stage (P<0.05). The score of HRQOL was better in males, undergraduates and above, unemployed/laid-off, and southwestern and central China. Multivariate analysis showed that education level, occupation, location, number of hospitals visited and treatment methods, and gender were associated with utilities of CRC patients.

Conclusions

The HRQOL is an important outcome measure for CRC patients. The HRQOL scores differed according to socio-demographic and clinical characteristics, and findings of these factors were associated with education level, occupation, region, number of visited and treatment methods, and gender.

Assessment of defecation function after sphincter-saving resection for mid to low rectal cancer: A cross-sectional study

PURPOSE

Patients with mid-to low-rectal cancer can have various dysfunctions of defecation after sphincter-saving resection. Defecation dysfunction can manifest as incontinence, urgency, or frequent bowel movements, and is called low anterior resection syndrome (LARS). This study aimed to examine LARS score and objective anorectal function indices in Chinese patients receiving sphincter-saving surgery for mid-to low-rectal cancer.

METHOD

This was a single-center cross-sectional study of patients undergoing sphincter-saving resection for low- or mid-rectal cancer and had restoration of trans-anal defecation for at least 1 month seen between January 2019 and June 2020. Patients completed a questionnaire regarding clinical characteristics, and Low Anterior Resection Syndrome (LARS) score and high-resolution anorectal manometry (HR-ARM) were used to assess defecation function. Multivariable analysis was used to identify variables significantly associated with defecation dysfunction.

RESULTS

146 patients completed and returned the questionnaires. 25 healthy adults also participated as control group for the anorectal manometry. Approximately 76% of patients developed LARS after surgery, of which 35.6% had major LARS. In these patients, anorectal manometry indices including initial rectal sensory capacity and rectal fecal sensory capacity, were significantly lower than normal. Logistic regression analysis showed that preoperative chemo-radiotherapy and the tumor inferior margins being close to the dentate line, especially 2-5 cm, were independent risk factors for defecation dysfunction after surgery.

CONCLUSIONS

Defecation dysfunction is a frequent occurrence after sphincter-saving resection for mid- and low-rectal cancer. Preoperative chemo-radiotherapy and a shorter tumor inferior margins distance to the dentate line are independent factors for defecation dysfunction.

Quality of life in restorative versus non-restorative resections for rectal cancer: systematic review

Background

Low rectal cancers could be treated using restorative (anterior resection, AR) or non-restorative procedures with an end/permanent stoma (Hartmann’s, HE; or abdominoperineal excision, APE). Although the surgical choice is determined by tumour and patient factors, quality of life (QoL) will also influence the patient's future beyond cancer. This systematic review of the literature compared postoperative QoL between the restorative and non-restorative techniques using validated measurement tools.

Methods

The review was registered on PROSPERO (CRD42020131492). Embase and MEDLINE, along with grey literature and trials websites, were searched comprehensively for papers published since 2012. Inclusion criteria were original research in an adult population with rectal cancer that reported QoL using a validated tool, including the European Organization for Research and Treatment of Cancer QLQ-CR30, QLQ-CR29, and QLQ-CR38. Studies were included if they compared AR with APE (or HE), independent of study design. Risk of bias was assessed using the Risk Of Bias In Non-Randomized Studies of Interventions (ROBINS-I) tool. Outcomes of interest were: QoL, pain, gastrointestinal (GI) symptoms (stool frequency, flatulence, diarrhoea and constipation), and body image.

Results

Nineteen studies met the inclusion criteria with a total of 6453 patients; all papers were observational and just four included preoperative evaluations. There was no identifiable difference in global QoL and pain between the two surgical techniques. Reported results regarding GI symptoms and body image documented similar findings. The ROBINS-I tool highlighted a significant risk of bias across the studies.

Conclusion

Currently, it is not possible to draw a firm conclusion on postoperative QoL, pain, GI symptoms, and body image following restorative or non-restorative surgery. The included studies were generally of poor quality, lacked preoperative evaluations, and showed considerable bias in the data.

Assessment and management of low anterior resection syndrome after sphincter preserving surgery for rectal cancer

Many patients develop a variety of bowel dysfunction after sphincter preserving surgeries (SPS) for rectal cancer. The bowel dysfunction usually manifests in the form of low anterior resection syndrome (LARS), which has a negative impact on the patients’ quality of life. This study reviewed the LARS after SPS, its mechanism, risk factors, diagnosis, prevention, and treatment based on previously published studies. Adequate history taking, physical examination of the patients, using validated questionnaires and other diagnostic tools are important for assessment of LARS severity. Treatment of LARS should be tailored to each patient. Multimodal therapy is usually needed for patients with major LARS with acceptable results. The treatment includes conservative management in the form of medical, pelvic floor rehabilitation and transanal irrigation and invasive procedures including neuromodulation. If this treatment failed, fecal diversion may be needed. In conclusion, Initial meticulous dissection with preservation of nerves and creation of a neorectal reservoir during anastomosis and proper Kegel exercise of the anal sphincter can minimize the occurrence of LARS. Pre-treatment counseling is an essential step for patients who have risk factors for developing LARS.

The effect of online training-based continuous nursing care for rectal cancer-patients undergoing permanent colostomy

OBJECTIVE

The study explored and analyzed the effects of online training based continuous nursing care on the health-related life quality and self-care ability of rectal cancer patients undergoing permanent colostomy.

METHODS

A total of 119 patients who were hospitalized and underwent permanent colostomy due to rectal cancer from January 2018 to December 2019 were collected as research subjects and were divided into the control group (n=57) and the observation group (n=62) based on their admission time. The control group received routine nursing, while the observation group was treated with online training based continuous nursing care in addition to routine nursing. Both groups' self-efficacy, self-care ability, quality of life, psychological status and complications within 6 months after discharge were compared.

RESULTS

Both groups had increased scores in self-efficacy, and their dimensional scores and total scores of self-care ability after intervention were higher compared with pre-intervention (P<0.05), and the indexes of the observation group after intervention were significantly higher than that of the control group (P<0.05). The two groups had remarkably increased SF-36 scores of each dimension after intervention compared with pre-intervention (P<0.05), and the observation group had apparently higher SF-36 scores than the control group after intervention (P<0.05). The two groups had increased SAS and SDS grades in post-intervention compared with pre-intervention (P<0.05), and the observation group had notably higher SAS and SDS scores than the control group (P<0.05). The complication rate within 6 months after discharge in the observation group was obviously lower than which in the control group (P<0.05).

CONCLUSION

An online training based continuous caring model can effectively improve the self-care ability and self-efficacy of rectal cancer patients with permanent enterostomy, thus promoting better life quality and psychological states, and effectively reducing the incidence of complications after discharge.

Management guidelines for low anterior resection syndrome - the MANUEL project

AIM

Little is known about the pathophysiology of low anterior resection syndrome (LARS), and evidence concerning the management of patients diagnosed with this condition is scarce. The aim of the LARS Expert Advisory Panel was to develop practical guidance for healthcare professionals dealing with LARS.

METHOD

The 'Management guidelines for low anterior resection syndrome' (MANUEL) project was promoted by a team of eight experts in the assessment and management of patients with LARS. After a face-to-face meeting, a strategy was agreed to create a comprehensive, practical guide covering all aspects that were felt to be clinically relevant. Eight themes were decided upon and working groups established. Each working group generated a draft; these were collated by another collaborator into a manuscript, after a conference call. This was circulated among the collaborators, and it was revised following the comments received. A lay patient revised the manuscript, and contributed to a section containing a patient's perspective. The manuscript was again circulated and finalized. A final teleconference was held at the end of the project.

RESULTS

The guidance covers all aspects of LARS management, from pathophysiology, to assessment and management. Given the lack of sound evidence and the often poor quality of the studies, most of the recommendations and conclusions are based on the opinions of the experts.

CONCLUSIONS

The MANUEL project provides an up-to-date practical summary of the available evidence concerning LARS, with useful directions for healthcare professional and patients suffering from this debilitating condition.

Quality of life in Mexican colorectal cancer patients: analysis with sociodemographic, medical, and psychological variables

In this study, we evaluated the influence of sex, age, clinical stage, and colostomy/ileostomy variables on the quality of life of Mexican patients with colorectal cancer. Using a descriptive cross-sectional design, 192 colorectal cancer patients were included in the study. Significant differences were observed in emotional functioning between patients with rectal cancer and those with colon cancer. Presence of colostomy/ileostomy was associated with significantly impaired social functioning. Body image was significantly different based on gender and diagnosis. Likewise, significant differences were observed with respect to symptoms of the general and specific quality of life modules for colorectal cancer: these included significant difference between male and female patients with respect to taste; significant difference between rectal and colon cancer with respect to presence of blood and mucous in stool, urinary incontinence, and buttock pain; and significant difference between patients with and without colostomy/ileostomy with respect to constipation, stool frequency, sore skin, and embarrassment. We observed significant correlation of dimensions of the quality of life with distress, post-traumatic stress, and optimism. Interventions for improving the quality of life of patients with colorectal cancer should be individualized based on the specific diagnosis and the presence/absence of colostomy/ileostomy.
