A Review of Male and Female Sexual Function Following Colorectal Surgery

Fertility Concerns Related to Surgery for Colorectal Cancer: An Under-Discussed Topic

As the incidence of colorectal cancer (CRC) increases among younger adults, the need for discussions regarding treatment-related infertility is growing. The negative impacts of gonadotoxic chemotherapy and pelvic radiation are well documented, but the role that surgical intervention for CRC plays in infertility is less clear. Additionally, treatment-related infertility counseling occurs infrequently. This review provides an overview of the connection between abdominal and pelvic surgery on male and female infertility and elucidates the role of surgeons in counseling to alleviate psychological distress in newly diagnosed patients. A review of the literature revealed that pelvic surgery leads to increased adhesion formation, which is known to be associated with female infertility. Furthermore, nerve damage from pelvic surgery has significant implications for ejaculatory issues in males and sexual dysfunction in both males and females, which ultimately impact pregnancy success. Patients have significant distress related to treatment-related infertility, and pre-treatment fertility counseling has been shown to alleviate some of this psychological burden. Nevertheless, many patients do not receive counseling, particularly in surgical clinics, despite surgeons often being the first providers to see newly diagnosed non-metastatic patients. Efforts should be made to enact protocols that ensure fertility conversations are being had with patients in surgical clinics and that patients are being referred to fertility specialists appropriately. This patient-centered approach will lessen the psychological burden placed on patients during a vulnerable time in their lives.

Sex Disparities in Rectal Cancer Surgery: An In-Depth Analysis of Surgical Approaches and Outcomes

Anatomical and physiological differences exist between sex, leading to variations in how diseases, such as rectal cancer, are prevalence and treatment outcomes of diseases including rectal cancer. In particular, in the case of rectal cancer, anatomical differences may be associated with surgical challenges, and these factors are believed to be important contributors to potential disparities in postoperative recovery, associated complications, and oncological outcomes between male and female patients. However, there is still ongoing debate regarding this matter. Significantly, the male pelvic anatomy is distinguished by its narrower dimensions, which can present surgical challenges and impede visual access during operative procedures, rendering it more complex than surgical interventions in the female pelvis. As a result, this anatomical difference leads to a greater occurrence of postoperative complications, such as anastomotic leakage. Moreover, the pelvis houses nerves that are vital for urinary and genital functions, underscoring the need to assess the potential risks of sexual and urinary dysfunction in rectal cancer surgery. These postoperative complications can significantly impact the quality of life; therefore, it is imperative to perform surgery with an understanding of the structural differences between sexes. Therefore, to address the limitations imposed by anatomical structures, new approaches such as robotic surgery, trans-anal total mesorectal excision, and intraoperative neuromonitoring are being introduced. Furthermore, it is essential to conduct research into fundamental mechanisms that may give rise to differences in surgical outcomes and oncological results between sexes. By comprehending the disparities between males and females, we can advance toward personalized treatments. Consequently, this review outlines variations in surgical approaches, complications, and treatments for rectal cancer in male and female patients.

Effect of a telephone-based perioperative nurse-led counselling programme on unmet needs, quality of life and sexual function in colorectal cancer patients: A non-randomised quasi-experimental study

PURPOSE

To investigate the effect of perioperative nurse-led counselling intervention on unmet needs, sexual function and quality of life in colorectal cancer patients.

METHOD

This quasi-experimental study included 82 patients who underwent colorectal cancer surgery (control n = 45, intervention n = 37). The telephone-based perioperative nurse-led counselling intervention, which contained implementation, follow-up, and assessment, was applied to start from pre-surgery to post-surgery 3rd month. Data were collected with the Unmet Needs of Cancer Survivors Scale, European Organisation for Treatment and Research of Cancer Quality of Life Scale-30, Colorectal-29, Female Sexual Function Index, and International Index of Erectile Function pre- and post-surgery 3rd-6th months. The control data was collected before the pandemic, and the intervention group throughout the pandemic. The Mann-Whitney-U, Wilcoxon rank test was used.

RESULTS

Compared to the control group, intervention group patients reported lower unmet and total needs scores (p = 0.000); higher quality of life (p = 0.000), physical, emotional (p = 0.000), role (p = 0.001), and social functioning scores (p = 0.002); lower fatigue (p = 0.000), constipation (p = 0.034), pain (p = 0.018), nausea-vomiting (p = 0.004), and insomnia scores (p = 0.003); and higher body image, anxiety (p = 0.000) and weight scores (p = 0.003), lower urinary frequency buttock pain (p = 0.000), dysuria (p = 0.001), abdominal pain (p = 0.001), fluctuance (p = 0.000), stool frequency (p = 0.002), and faecal incontinence (p = 0.006) scores at the sixth month (p < 0.05). There were no statistically significant differences between male and female sexual function scores (p > 0.05).

CONCLUSIONS

Perioperative nurse-led counselling reduced unmet needs and increased the overall quality of life by decreasing symptom levels but did not affect sexual health outcomes in patients with colorectal cancer surgery.

Prophylactic mastectomy and bilateral salpingo-oophorectomy in patients with breast cancer: a systematic review of postsurgical sexual function and menopausal hormone therapy symptom mitigation

INTRODUCTION

Preventative surgical procedures for patients who are breast cancer (BRCA) positive-namely, bilateral salpingo-oophorectomy and mastectomy-have been linked to changes in sexual function, including surgically induced menopause. A patient's decision to undergo preventive surgery as opposed to high-risk screening is heavily reliant on advice received from one's health care provider. Quality of life should be considered when shared decision making is conducted with patients.

OBJECTIVES

To assemble and analyze findings related to patient-reported sexual function after these surgical procedures, to see if and how either procedure affects sexual function from patient baseline, and to determine whether the effects can be mitigated with menopausal hormone therapy.

METHODS

A literature review based on the PubMed, Embase, and MEDLINE databases was conducted from inception through January 25, 2022. To be included, studies had to meet an a priori list of Medical Subject Headings: "BRCA" AND "sexual dysfunction" OR "dyspareunia." GRADE criteria were used to determine the quality of studies relating to menopause hormone therapy.

RESULTS

The search yielded 14 results, and 11 reported sufficient data for systematic review. Sexual function was measured via validated and investigator-generated surveys. All studies, no matter the survey metric, found significant reduction in sexual function with bilateral salpingo-oophorectomy; no studies revealed sexual function changes associated with mastectomy postsurgery. Few studies indicated that menopause hormone therapy resulted in significant improvement in sexual function, and all studies reported that postoperative sexual function could not reach baseline levels with therapy. No studies were high quality by GRADE metrics.

CONCLUSION

Prophylactic mastectomies and bilateral salpingo-oophorectomies among patients who are BRCA positive cause SF changes postprocedure. Menopausal hormone therapy offers little help in mediating symptoms. Significantly more research is needed to explore potential changes in sexual function, as it is an important aspect of quality of life for patients with BRCA positivity.

A systematic review of female sexual function after surgery for locally advanced or recurrent colorectal cancer - first step to filling the knowledge gap

AIM

Locally advanced and recurrent colorectal cancer can require extended surgery, including reconstruction of the vagina. This complex surgery carries high morbidity. The aim of this study was to analyse the impact on female sexual functioning of pelvic exenteration (PE), with or without vaginal flap reconstruction, for locally advanced or recurrent colorectal cancer.

METHOD

The protocol with search strategies for PubMed (Medline), EMBASE and the Cochrane Library was registered in PROSPERO. Studies published from 2000 onwards meeting the inclusion criteria were considered. Study selection (Rayyan), data extraction, rating of evidence (GRADE) and risk of bias (ROBINS-I) were conducted independently by two reviewers.

RESULTS

Six of 2479 identified records were included: four retrospective and two cross-sectional studies. Of all 860 patients included, PE was performed in 314 patients. Seven hundred and thirty-two had rectal cancer (85.1%), 80 nonadvanced rectal cancer (10.9%), 393 locally advanced rectal cancer (53.7%) and 217 locally recurrent rectal cancer (29.6%); for 45 patients the type of rectal cancer remained unspecified (6.1%). Three studies reported on both preoperative and postoperative female sexual activity. Of the 153 women who were sexually active preoperatively, 64 (41.8%) reported postoperative sexual activity. The VRAM flap was used the most frequently and resulted in a sexual activity ratio of 18% postoperatively. Four studies, using six different validated questionnaires, reported mostly lowered sexual functioning postoperatively.

CONCLUSION

Most studies showed that PE can result in severe sexual dysfunction despite reconstruction. Future prospective studies can fill the current knowledge gap by assessing long-term sexual outcomes in women.

Intimacy and survivors of cancer with ostomies: findings from the Ostomy Self-management Training trial

BACKGROUND

Many people with abdominal or pelvic cancers require an ostomy during surgical treatment, which can cause significant issues with physical and emotional intimacy in relationships.

AIM

To evaluate the effect of a telehealth-based education program on intimacy over time for survivors of cancer with ostomies.

METHODS

We performed a secondary analysis of our multicenter randomized controlled trial to determine intimacy outcomes and to compare the effects of the Ostomy Self-management Training (OSMT) program vs usual care. Partnered patients were included who provided answers to the City of Hope Quality of Life-Ostomy survey for at least 2 time points during the study. We evaluated the effect of baseline information, such as gender on intimacy.

OUTCOMES

The primary outcome was intimacy, estimated by a composite score created from questions within the City of Hope Quality of Life-Ostomy survey.

RESULTS

Of 216 enrolled volunteers, 131 had a partner: 68 in the OSMT arm and 63 in the usual care arm. Of these, 48 were women and 83 were men. The tumor types represented in this study were colorectal (n = 69), urinary (n = 45), gynecologic (n = 10), and other (n = 7; eg, melanoma, liposarcoma). From the cohort, 87 answered the 5 composite intimacy score questions at 2 time points, including baseline. There was significant improvement over time in composite intimacy scores for participants in the OSMT arm vs the usual care arm.

CLINICAL IMPLICATIONS

Our OSMT intervention had a positive effect on factors that contribute to intimacy for survivors of cancer with ostomies, suggesting that a survivorship curriculum can improve their experiences after ostomy surgery.

STRENGTHS AND LIMITATIONS

OSMT allowed for discussion of intimacy and other sensitive topics, which can be challenging. These discussions demonstrate benefit to participants and can serve as frameworks for cancer treatment providers. The focus of this work on partnered participants provides insight into the interpersonal challenges of a life with an ostomy, but it may overlook the important perspectives of nonpartnered participants and the partners themselves. Furthermore, limited power prevented us from conducting subgroup analyses exploring the effects of factors such as gender and tumor type on intimacy.

CONCLUSION

At 6-month follow-up, the novel intimacy composite score indicated improvement for participants completing the OSMT intervention. Future research studies with higher power will validate this intimacy measurement and identify intimacy differences in similar populations based on tumor type.

The protective role of phosphodiesterase inhibitors in preventing colorectal cancer and advanced colorectal polyps: a systematic review and meta-analysis

AIM

Inflammatory cells within the tumour microenvironment are the driving forces behind colorectal cancer (CRC) tumourigenesis. Understanding the different pathways involved in CRC carcinogenesis paves the way for effective repurposing of drugs for cancer prevention. Emerging data from preclinical and clinical studies suggest that, due to their antiproliferative and anti-inflammatory properties, phosphodiesterase-5 inhibitors (PDE5i) might have an anticancer effect. The aim of this study was to clarify through systematic review and meta-analysis of published peer-reviewed studies whether an association exists between PDE5i use and CRC risk.

METHOD

This study was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Prospective registration was performed on PROSPERO (CRD42022372925). A systematic review was performed for studies reporting CRC and advanced colorectal polyp incidence in PDE5i 'ever-users' and PDE5i 'never-users'. Meta-analysis was performed using RevMan version 5.

RESULTS

Four observational cohort studies and two case-control studies, comprising 995 242 patients were included in the final analysis, of whom 347 126 were PDE5i ever-users. Patients who were PDE5i ever-users had a significantly lower incidence of CRC or advanced colorectal polyps than never-users (OR 0.88, CI 0.79-0.98, p = 0.02). To examine the primary preventative role of PDE5i, subgroup analysis of four studies including patients without a previous history of CRC found that use of PDE5i was associated with a lower incidence of CRC (OR 0.85, CI 0.75-0.95, p = 0.005, I2  = 64%). There was no significant temporal relationship found between PDE5i use and CRC risk as both current users and previous users had a significantly lower incidence of CRC than never-users.

CONCLUSION

Our study found a significant anticancer effect of PDE5i, as shown by a reduced risk of CRC in the context of both primary and secondary CRC prevention.

Sexual health problems of patients with cancer: A bibliometrics study and visualization analysis via CiteSpace

Purpose

This study aimed to conduct a bibliometric analysis of the data acquired and clarified the current research status of sexual health problems in patients with cancer, to provide a comprehensive visual perspective suitable as a reference for subsequent research.

Methods

We searched the Web of Science Core Collection (WoSCC) up to April 30, 2023 to identify studies associated with sexual health problems in patients with cancer. CiteSpace was used to create visualization networks for countries, institutions, authors, and journals.

Results

A total of 3183 publications related to sexual health problems in patients with cancer were collected from the WoSCC. In terms of volume, the USA (1259 papers) was the leading country, the Memorial Sloan Kettering Cancer Center (119 papers) was the leading institution, and Carter (39 papers) was the author with the most publications. The top-cited references and keywords were related to quality of life. The top five clusters of reference cocitation were 'brachytherapy', 'prostate cancer', 'radical prostatectomy', 'hypogonadism', and 'breast cancer'. Meanwhile, the top five clusters of keyword cocitation were 'breast cancer', 'prostate cancer', 'rectal cancer', 'testicular cancer', and 'sexual function'. The analysis of the top 25 references and keywords with the strongest citation bursts of published papers on sexual health problems in patients with cancer to reveal the research hotspots and trends.

Conclusions

Research on sexual health among patients with cancer is constantly developing. The current research focuses on the impact of different treatment options for sexual health and quality of life of patients with breast, rectal, and genitourinary neoplasms. Exploring the long-term changing regularities of sexual function among cancer survivors and formulating sexual health interventions toward patient-reported outcomes and needs are key research directions.

Incidence and Factors Associated With Mental Health Disorders in Patients With Rectal Cancer Post-Restorative Proctectomy

BACKGROUND

Most patients with rectal cancer experience bowel symptoms post-restorative proctectomy. The incidence of mental health disorders post-restorative proctectomy and its association with bowel symptoms are unknown.

OBJECTIVES

This study aimed 1) to describe the incidence of mental health disorders in patients who underwent restorative proctectomy for rectal cancer and 2) to study the association between incident mental health disorders and bowel dysfunction after surgery.

DESIGN

This retrospective cohort study used the Clinical Practice Research Datalink and Hospital Episode Statistics databases.

SETTINGS

The databases were based in the United Kingdom.

PATIENTS

All adult patients who underwent restorative proctectomy for a rectal neoplasm between 1998 and 2018 were included.

MAIN OUTCOME MEASURES

The primary outcome was an incident mental health disorder. The associations between bowel, sexual, and urinary dysfunctions and incident mental health disorders were studied using Cox proportional hazard regression models.

RESULTS

In total, 2197 patients who underwent restorative proctectomy were identified. Of 1858 patients without preoperative bowel, sexual, or urinary dysfunction, 1455 had no preoperative mental health disorders. In this cohort, 466 patients (32.0%) developed incident mental health disorders following restorative proctectomy during 6333 person-years of follow-up. On multivariate Cox regression, female sex (adjusted HR 1.30; 95% CI, 1.06-1.56), metastatic disease (adjusted HR 1.57; 95% CI, 1.14-2.15), incident bowel dysfunction (adjusted HR 1.41, 95% CI, 1.13-1.77), and urinary dysfunction (adjusted HR 1.57; 95% CI, 1.16-2.14) were found to be associated with developing incident mental health disorders post-restorative proctectomy.

LIMITATIONS

This study was limited by its observational study design and residual confounding.

CONCLUSIONS

Incident mental health disorders after restorative proctectomy for rectal cancer are common. The presence of bowel and urinary functional impairment significantly increases the risk of poor psychological outcomes among rectal cancer survivors.

Impact on defecatory, urinary and sexual function after high-tie sigmoidectomy: a post-hoc analysis of a multicenter randomized controlled trial comparing extended versus standard complete mesocolon excision

OBJECTIVE

To assess the effect of high inferior mesenteric artery tie on defecatory, urinary, and sexual function after surgery for sigmoid colon cancer. Performing a sigmoidectomy poses a notable risk of causing injury to the preaortic sympathetic nerves during the high ligation of the inferior mesenteric artery, as well as to the superior hypogastric plexus during dissection at the level of the sacral promontory. Postoperative defecatory and genitourinary dysfunction after sigmoid colon resection are often underestimated and underreported.

METHODS

This study is a secondary research of a multicenter, single-blind, randomized clinical trial. The trial involved patients with sigmoid cancer who underwent either extended complete mesocolic excision (e-CME) or standard CME (s-CME). Patients completed questionnaires to assess defecatory, urinary, and sexual function before, 1 month after surgery, and 1 year after surgery. Multivariate analysis was conducted to identify factors associated with functional dysfunction.

RESULTS

Seventy-nine patients completed functional assessments before and 1 year after surgery. One year after sigmoidectomy with a high tie of the inferior mesenteric artery, 15.2% of patients had minor low anterior resection syndrome (LARS) and 12.7% had major LARS; 22.2% of males and 29.4% of females had urinary dysfunction; and 43.8% of males and 27.3% of females had sexual dysfunction. After multivariate analysis, no significant associations were found between clinical and surgical factors and gastrointestinal or urinary dysfunction after 1 year of surgery. Age was identified as the only factor linked to sexual dysfunction in both sexes (women, β =  - 0.54, p = 0.002; men β =  - 0.38, p = 0.010). Regarding recovery outcomes, diabetes mellitus was identified as a contributing factor to suboptimal gastrointestinal recovery (p = 0.033) and urinary recovery in women (p = 0.039). Furthermore, the treatment arm was found to be significantly associated with the recovery of erectile function after 1 year of surgery (p = 0.046).

CONCLUSIONS

A high tie of the inferior mesenteric artery during sigmoidectomy is associated with a high incidence of defecatory and genitourinary dysfunction. Age was identified as a significant factor associated with sexual dysfunction 1 year after sigmoid colon resection in both sexes.

TRIAL REGISTRATION

Clinical trials NCT03083951 HIGHLIGHTS: • One year after high-tie sigmoidectomy, 27.9% of patients had LARS; 22.2% of the men and 29.4% of the women had urinary dysfunction; and 43.8% of the men and 27.3% of the women had sexual dysfunction. • e-CME is associated with a high rate of urinary dysfunction in men 1 year after surgery. However, after multivariate analysis, no association was found between e-CME and urinary dysfunction in men. • Age was correlated with the recovery of sexual function in both sexes 1 year after surgery. Furthermore, diabetes mellitus was identified as the factor associated with poorer recovery of urinary function in females.

Psychometric Evaluation of the Postoperative Recovery Profile

Aim

To further evaluate the postoperative recovery profile regarding its psychometric properties.

Background

The postoperative recovery profile is an instrument for the self-assessment of general postoperative recovery that has received increased attention within nursing research. However, psychometric evaluation during development was sparse.

Design

Psychometric evaluation was done using classical test theory.

Method

Data quality, targeting, reliability, and scaling assumptions were measured. In addition, confirmatory factor analysis was used to evaluate construct validity. Data collection was made during 2011-2013.

Result

Data derived from this study showed acceptable quality; however, item distribution was skewed, with ceiling effects in the majority of items. Cronbach's alpha showed high internal consistency. Item-total correlations indicated unidimensionality, whereas six items demonstrated high correlations pointing at redundancy. The confirmatory factor analysis confirmed problems related to dimensionality as the five proposed dimensions were highly correlated with each other. Furthermore, items were largely uncorrelated with the designated dimensions.

Conclusion

This study shows that the postoperative recovery profile needs to be further developed to serve as a robust instrument within nursing as well as medical research. Arguably, values from the instrument should not be calculated at a dimensional level for the time being because of discriminant validity issues.

Implantation of skin-derived precursor Schwann cells improves erectile function in a bilateral cavernous nerve injury rat model

BACKGROUND

This study was conducted to investigate the therapeutic potential of the skin-derived precursor Schwann cells for the treatment of erectile dysfunction in a rat model of bilateral cavernous nerve injury.

RESULTS

The skin-derived precursor Schwann cells-treatment significantly restored erectile functions, accelerated the recovery of endothelial and smooth muscle tissues in the penis, and promoted nerve repair. The expression of p-Smad2/3 decreased after the treatment, which indicated significantly reduced fibrosis in the corpus cavernosum.

CONCLUSIONS

Implantation of skin-derived precursor Schwann cells is an effective therapeutic strategy for treating erectile dysfunction induced by bilateral cavernous nerve injury.

Erectile Dysfunction in Pelvic Cancer Survivors and Current Management Options

Pelvic malignancies, including prostate, rectal, and bladder cancers, are among the most frequent malignancies found in the male population. These issues are most effectively and commonly treated with radiotherapy and/or surgery. However, these treatments can cause collateral damage, resulting in significant impacts on quality of life, with erectile dysfunction being one of the most frequent postoperative complications. Currently, there are several treatment options for erectile dysfunction, including oral phosphodiesterase type 5 inhibitors, vacuum erection devices, intracorporeal injections, and penile prosthesis. The latter has shown to be an effective and safe technique, with results comparable to those obtained by patients without pelvic surgery or radiotherapy. The results of early penile rehabilitation programs are promising and they have been incorporated into a greater proportion of treatment plans more recently, with varying degrees of success. In this narrative review, we summarize the literature on erectile dysfunction after pelvic cancer treatments and its management.

Do colorectal cancer patients with a postoperative stoma have sexual problems? A pooling up analysis of 2566 patients

PURPOSE

This study aimed to evaluate the effect of the stoma on sexual function in colorectal cancer patients.

METHODS

Search strategy was conducted in four databases including PubMed, Embase, the Cochrane Library, and Medline on Nov 20, 2022. After that, the quality of eligible studies was assessed by the Newcastle Ottawa Scale (NOS) and the Agency for Healthcare Research Quality (AHRQ). In order to evaluate the sexual function between the stoma group and the non-stoma group, mean values and standard deviation were pooled for scores in questionnaires, and odds ratio and 95% confidence intervals were pooled for self-designed problems. Results were shown in forest plots; Egger's test and the trim and fill analysis were used for assessing the publication bias. All the data analyses above were performed by STATA 16.0 software.

RESULTS

Six cohort studies and three cross-sectional studies were included for this pooling up analysis. As for the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ-C38), male patients with stomas had more sexual problems (mean differences = 0.32, 95% confidence intervals = 0.01 to 0.63, I² = 67.80%, P = 0.05); however, other indicators including sexual functioning, sexual enjoyment, and female sexual problems had little difference between the two groups. As for other questionnaires and problems, stoma did not have an impact on sexual function.

CONCLUSION

The stoma after surgery was not significantly associated with the sexual function of female patients with colorectal cancer and was associated with worse scores on only sexual problems for males.

Prospective Evaluation of the Quality of Life of Patients after Surgical Treatment of Rectal Cancer: A 12-Month Cohort Observation

This study constitutes a prospective, three-stage evaluation of quality of life among patients receiving surgical treatment for colorectal cancer depending on the type of surgery performed (open anterior resection, laparoscopic anterior resection, abdominoperineal resection, or Hartmann’s procedure). The study included 82 patients treated at the Surgical Oncology Outpatient Department of the Oncology Center in Bydgoszcz from June 2019 to August 2021. The study tools consisted of diagnostic surveys and analyses of medical records. The standardized study tools were the surveys EORTC QLQ-C30 and QLQ-CR29. In addition, a proprietary questionnaire was developed to collect demographic data. Quality of life was measured at three time-points: the day before the surgery and 6 and 12 months post-surgery. Statistically significant differences (p < 0.05) were observed in the domains of role functioning (III, p = 0.030), body image (II, p < 0.001; III, p < 0.001), sexual functioning (II, p = 0.037), buttocks/anal area/rectum pain (III, p = 0.031), and embarrassment (II, p = 0.022; III, p = 0.010). Statistically significant differences in the functional and symptom scale scores were also observed within each group at different stages of cancer treatment. As shown by our study, the quality of life of patients treated for colorectal cancer is determined not only by the operating technique but also by sociodemographic and clinical factors. The use of minimally invasive surgical techniques enables patients to return to their social roles more quickly and improves their self-assessment of body image.

Long-term quality of life, sexual health and gastrointestinal function following colorectal cancer resection in an Asian cohort

AIM

As populations age and cancer management improves, long-term survivorship and quality-of-life (QOL) outcomes are becoming equally important as oncological results. Data from Asian populations are scarce. We aimed to evaluate the sexual health, gastrointestinal function and QOL amongst colorectal cancer survivors in a tertiary referral centre in Singapore.

METHOD

Adults who had undergone elective curative surgery for non-metastatic colorectal cancer at least 2 years prior were included. Exclusion criteria were cognitive disease, serious postoperative complications or recurrent cancer. Participants were invited to complete the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires EORTC-QLQ-C30 and QLQ-CR29. Using multiple bivariate analysis, r scores were used to examine relationship trends between QOL domains and survivor sociodemographic and disease-specific characteristics.

RESULTS

From February 2017 to July 2019, 400 responses were recorded. Median age and follow-up duration were 64 years (range 32-90) and 78 months (interquartile range 49-113) respectively. Patients who had Stage III cancer had better overall QOL scores compared to Stage I/II. Rectal (vs. colon) cancer negatively influenced sexual health and gastrointestinal function, but did not appear to affect overall QOL. Amongst our cohort, 57% (n = 129) of men and 43% (n = 75) of women were sexually active. Markers of socioeconomic status, including employment, education and housing type, were found to significantly impact perception of various aspects of QOL.

CONCLUSION

Knowledge of factors which influence well-being can identify individuals who may benefit from tailored management strategies. Regular patient-doctor contact may play a role in building and maintaining positive perspectives of cancer survivors. Normative data should be obtained from local populations to facilitate future comparative research.

Nerve plane: An optimal surgical plane for laparoscopic rectal cancer surgery?

Radical resection for rectal cancer with total mesorectal excision has been widely recognized in mid-low rectal cancer. Although such surgery reduced the tumor recurrence rate and improved the survival rate of patients, the rate of urinary and sexual dysfunction was high after rectal cancer surgery, which might be attributed to pelvic autonomic nerve injury. The present study found that the pelvic autonomic nerves never exist alone. These are always surrounded by tiny capillaries and adipose tissue and covered by a thin layer of membranous tissue, leading to a continuous plane that should be preserved pelvic autonomic nerve from thermal damage, ischemic injury, nerve stretching, and chemical factors produced by local inflammatory effects. However, the completeness of the continuous plane is easily damaged intraoperatively in routine total mesorectal excision in rectal cancer. Postoperative urinary and sexual dysfunction might be closely associated with the injury of continuous plane. Therefore, the continuous plane should be protected and considered as the optimal surgical plane for rectal cancer surgery.

Prevalence and predictors of poor sexual well-being over 5 years following treatment for colorectal cancer: results from the ColoREctal Wellbeing (CREW) prospective longitudinal study

OBJECTIVES

To describe prevalence and predictors of poor sexual well-being for men and women over 5 years following treatment for colorectal cancer.

DESIGN

Prospective longitudinal study, from presurgery to 5 years postsurgery, with eight assessment points. Logistic regression models predicted sexual well-being from presurgery to 24 months and 24 months to 60 months; time-adjusted then fully adjusted models were constructed at each stage.

SETTING

Twenty-nine hospitals in the UK.

PARTICIPANTS

Patients with Dukes' stage A-C, treated with curative intent, aged ≥18 years and able to complete questionnaires were eligible.

OUTCOME MEASURES

The dependent variable was the Quality of Life in Adult Cancer Survivors sexual function score. Independent variables included sociodemographic, clinical and psychosocial characteristics.

RESULTS

Seven hundred and ninety participants provided a sexual well-being score for at least one time point. Thirty-seven per cent of men and 14% of women reported poor sexual well-being at 5 years. Baseline predictors for men at 24 months included having a stoma (OR 1.5, 95% CI 1.02 to 2.20) and high levels of depression (OR 2.69/2.01, 95% CI 1.68 to 4.32/1.12 to 3.61); men with high self-efficacy (OR confident 0.33/0.48, 95% CI 0.18 to 0.61/0.24 to 1.00; very confident 0.25/0.42, 95% CI 0.13 to 0.49/0.19 to 0.94) and social support (OR 0.52/0.56, 95% CI 0.33 to 0.81/0.35 to 0.91) were less likely to report poor sexual well-being. Predictors at 60 months included having a stoma (OR 2.30/2.67, 95% CI 1.22 to 4.34/1.11 to 6.40) and high levels of depression (OR 5.61/2.58, 95% CI 2.58 to 12.21/0.81 to 8.25); men with high self-efficacy (very confident 0.14, 95% CI 0.047 to 0.44), full social support (OR 0.26; 95% CI 0.13 to 0.53) and higher quality of life (OR 0.97, 95% CI 0.95 to 0.98) were less likely to report poor sexual well-being. It was not possible to construct models for women due to low numbers reporting poor sexual well-being.

CONCLUSIONS

Several psychosocial variables were identified as predictors of poor sexual well-being among men. Interventions targeting low self-efficacy may be helpful. More research is needed to understand women's sexual well-being.

PDE-5i Management of Erectile Dysfunction After Rectal Surgery: A Systematic Review Focusing on Treatment Efficacy

Erectile dysfunction (ED) is one of the main functional complications of surgical resections of the rectum due to rectal cancers or inflammatory bowel disease (IBD). The present systematic review aimed at revising ED management strategies applied after rectal resections and their efficacy in terms of improvement of the International Index of Erectile Function (IIEF) score. A literature search was conducted on Medline, EMBASE, Scopus, and Cochrane databases by two independent reviewers following the PRISMA guidelines. Randomized and nonrandomized controlled trials (RCTs, NRCTs), case-control studies, and case series evaluating medical or surgical therapies for ED diagnosed after rectal surgery for both benign and malignant pathologies were eligible for inclusion.

Out of 1028 articles initially identified, only five met the inclusion criteria: two RCTs comparing oral phosphodiesterase type-5 inhibitor (PDE-5i) versus placebo; one NRCT comparing PDE-5i versus PDE-5i + vacuum erection devices (VEDs) versus control; and two before-after studies on PDE-5i. A total of 253 (82.7%) rectal cancer patients and 53 (17.3%) IBD patients were included. Based on two RCTs, PDE-5i significantly improved IIEF compared to placebo at 3 months (SMD = 1.07; 95% CI [0.65, 1.48]; p < .00001; I² = 39%). Improved IIEF was also reported with PDE-5i + VED at 12 months. There is a paucity of articles in the literature that specifically assess efficacy of ED treatments after rectal surgery. Many alternative treatment strategies to PDE-5is remain to be investigated. Future studies should implement standardized preoperative, postoperative, and follow-up sexual function assessment in patients undergoing rectal resections.
