Quality of Life after Open or Minimally Invasive Esophagectomy in Patients With Esophageal Cancer-A Systematic Review

Severe reflux, malnutrition and health-related quality of life after oesophageal cancer surgery: A prospective nationwide cohort study

INTRODUCTION

While most survivors of oesophageal cancer suffer from multiple symptoms, studies on combined symptom burden are scarce, particularly when looking at long-term outcomes. Therefore, we aimed to investigate the association between gastro-oesophageal reflux and health-related quality of life in malnourished survivors during the first years after oesophagectomy for cancer.

MATERIALS AND METHODS

This nationwide prospective cohort study included all Swedish patients who underwent curatively intended oesophagectomy for oesophageal cancer between 2013 and 2020 with 3-year follow-up. Linear mixed effect models were used to analyse the associations between reflux symptoms, malnutrition and HRQL at 1-, 2- and 3 years post-surgery and were presented with mean score difference (MSD) and 95 % confidence intervals (CI).

RESULTS

Among 406 included individuals, malnourished survivors with severe reflux reported more problems with nausea/vomiting (MSD 16.3, 95 % CI: 11.4 to 21.3), pain (MSD 16.5, 95 % CI: 10.2 to 22.8), body image (MSD 12.3, 95 % CI: 5.6 to 19.0), eating restrictions (MSD 11.3, 95 % CI: 6.1 to 16.5), swallowing saliva (MSD 10.0, 95 % CI: 5.2 to 14.8), dry mouth (MSD 10.5, 95 % CI: 2.4 to 18.7), and taste (MSD 14.1, 95 % CI: 7.1 to 21.0) compared to malnourished survivors with no reflux. Nausea/vomiting, financial difficulties, body image, and cognitive function were consistently worse for malnourished individuals with reflux throughout the 3 years.

CONCLUSIONS

The study suggests that gastro-oesophageal reflux negatively influences health-related quality of life in malnourished oesophageal cancer survivors. Nausea and/or vomiting were consistently worse for malnourished individuals with reflux independent of time point.

Association of perioperative oral swallowing function with post-esophagectomy outcomes and nutritional statuses in patients with esophageal cancer

Dysphagia after esophagectomy is a serious complication; however, no method has been established to accurately assess swallowing function. We evaluated the association of swallowing function tests with patients' post-esophagectomy complications and nutritional statuses. We retrospectively reviewed the data of 95 patients with esophageal cancer who underwent esophagectomy between 2016 and 2021. We performed perioperative swallowing function tests, including the repetitive saliva swallowing test (RSST), maximum phonation time (MPT), and laryngeal elevation (LE). Patients with recurrent laryngeal nerve palsy (RLNP) and respiratory complications (RC) had significantly lower postoperative RSST scores than patients without them; the scores in patients with or without anastomotic leakage (AL) were similar. Postoperative MPT in patients with RLNP was shorter than that in patients without RLNP; however, it was similar to that in patients with or without AL and RC. LE was not associated with any complications. Patients with an RSST score ≤2 at 2 weeks post-esophagectomy had significant weight loss at 1, 6, and 12 months postoperatively compared with patients with an RSST score ≥3. The proportion of patients with severe weight loss (≥20% weight loss) within 1 year of esophagectomy was significantly greater in patients with RSST scores ≤2 than in those with RSST scores ≥3. Multivariate analysis showed that an RSST score ≤2 was the only predictor of severe post-esophagectomy weight loss. RSST scoring is a simple tool for evaluating post-esophagectomy swallowing function. A lower RSST score is associated with postoperative RLNP, RC, and poor nutritional status.

Long-term quality of life after hybrid robot-assisted and open Ivor Lewis esophagectomy for esophageal cancer in a single center: a comparative analysis

PURPOSE

Due to improved survival of esophageal cancer patients, long-term quality of life (QoL) is increasingly gaining importance. The aim of this study is to compare QoL outcomes between open Ivor Lewis esophagectomy (Open-E) and a hybrid approach including laparotomy and a robot-assisted thoracic phase (hRob-E). Additionally, a standard group of healthy individuals serves as reference.

METHODS

With a median follow-up of 36 months after hRob-E (n = 28) and 40 months after Open-E (n = 43), patients' QoL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QoL Questionnaire Core 30 (QLQ-C30) and the EORTC Esophagus specific QoL questionnaire 18 (QLQ-OES18).

RESULTS

Patients showed similar clinical-pathological characteristics, but hRob-E patients had significantly higher ASA scores at surgery (p < 0.001). Patients and healthy controls reported similar global health status and emotional and cognitive functions. However, physical functioning of Open-E patients was significantly reduced compared to healthy controls (p = 0.019). Operated patients reported reduced role and social functioning, fatigue, nausea and vomiting, dyspnea, and diarrhea. A trend towards a better pain score after hRob-E compared to Open-E emerged (p = 0.063). Regarding QLQ-OES18, hRob-E- and Open-E-treated patients similarly reported eating problems, reflux, and troubles swallowing saliva.

CONCLUSIONS

The global health status is not impaired after esophagectomy. Despite higher ASA scores, QoL of hRob-E patients is similar to that of patients operated with Open-E. Moreover, patients after hRob-E appear to have a better score regarding physical functioning and a better pain profile than patients after Open-E, indicating a benefit of minimally invasive surgery.

[Evidence for Minimal Invasive Oesophageal Resection]

In the course of the last 20 years, minimally invasive therapy has become much more important in all areas. In particular, surgical procedures have been established in oncological surgery, even without generating the necessary evidence to assure that the quality is equal to that achieved with open procedures. For this purpose, it has only been in recent years that appropriate randomised controlled studies followed by meta-analyses have been carried out. In this article, we summarise the evidence for minimally invasive resection of the oesophagus and review current literature for each procedure.

Self-care advice for patients after surgery for oesophageal cancer - a mixed-methods systematic review

PURPOSE

The aim of the literature review was to identify and synthesise research on self-care advice for oesophageal cancer survivors.

METHODS

A mixed-methods systematic review and synthesis of existing literature on the topic. Five databases were searched for studies providing information on self-care advice for survivorship after oesophageal cancer surgery, in English, with no time filter. The Critical Appraisal Skills Program was used to assess the risk of bias. Data were presented by textual descriptions and grouping of data.

RESULTS

Among the 13 studies included in the review, five pieces of self-care advice were identified; reconstructing eating habits, bed-head elevation, health-promoting advice, monitoring symptoms and body functions, and involving family and friends. The self-care advice was experienced to be hard work, but worth the effort. They also provided reassurance and an increased understanding of bodily changes and social consequences of the disease and treatment.

CONCLUSIONS

There are is little evidence-based self-care advice for oesophageal cancer survivors. However, the existing self-care advice was appreciated and contributed to an increased understanding of the situation. Comprehensible and easy-to-follow recommendations should be provided to all oesophageal cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Evidence-based self-care advice helpful for the individual oesophageal cancer survivor may be imperative to cope with the consequences of oesophagectomy after hospital discharge.

Health-related quality of life 15 years after oesophageal cancer surgery: a prospective nationwide cohort study

PURPOSE

We aimed to study oesophageal cancer survivors' health-related quality of life (HRQL) 15 years after surgery and to identify factors related to reduced HRQL.

METHODS

A nationwide, prospective cohort study enrolling 616 patients who underwent open oesophageal cancer surgery in Sweden between April 2, 2001, and December 21, 2005. HRQL was evaluated by questionnaires 15 years after surgery. HRQL data for the 15-year survivors were individually matched for age, sex and comorbidity by using values from a Swedish background population. Multivariable linear regression models provided mean score differences (MSD) with 95% confidence intervals (CI) for each HRQL scale and item.

RESULTS

Among the 616 individuals in the original study group, 70 (11%) survived for 15 years and 52 (74%) responded to the questionnaires. Compared with a matched background population, the survivors reported problems in 10 of 25 HRQL aspects. Most of these were related to symptoms of the digestive tract, such as reflux (MSD 26.4, 95%CI: 18.3 to 34.4), dysphagia (MSD 17.7, 95%CI: 10.0 to 25.4) and eating difficulties (MSD 16.4, 95%CI: 11.3 to 21.4). Major postoperative complications after surgery were related to worse HRQL in 11 of 25 aspects.

CONCLUSIONS

This study suggests that surgery for oesophageal cancer entails long-term, possibly life-long, symptoms related to the digestive tract.

IMPLICATION FOR CANCER SURVIVORS

Comprehensive support from healthcare may be imperative for oesophageal cancer survivors to adapt to and cope with consequences of oesophageal cancer surgery. Prevention, early identification and adequate treatment of postoperative complications may improve patient outcome.

Caregiver burden and health-related quality of life among family caregivers of oesophageal cancer patients: a prospective nationwide cohort study

BACKGROUND

Oesophageal cancer surgery is extensive with high risk of long-term health-related quality of life (HRQL) reductions. After hospital discharge, the family members often carry great responsibility for the rehabilitation of the patient, which may negatively influence their wellbeing. The purpose was to clarify whether a higher caregiver burden was associated with psychological problems and reduced HRQL for family caregivers of oesophageal cancer survivors.

MATERIAL AND METHODS

This was a nationwide prospective cohort study enrolling family members of all patients who underwent surgical resection for oesophageal cancer in Sweden between 2013 and 2020. The family caregivers reported caregiver burden, symptoms of anxiety, depression, post-traumatic stress, and HRQL 1 year after the patient's surgery. Associations were analysed with multivariable logistic regression and presented as odds ratios (OR) with 95% confidence intervals (CI). Differences between groups were presented as mean score differences (MSD).

RESULTS

Among 319 family caregivers, 101 (32%) reported a high to moderate caregiver burden. Younger family caregivers were more likely to experience a higher caregiver burden. High-moderate caregiver burden was associated with an increased risk of symptoms of anxiety (OR 5.53, 95%CI: 3.18-9.62), depression (OR 8.56, 95%CI: 3.80-19.29), and/or posttraumatic stress (OR 5.39, 95%CI: 3.17-9.17). A high-moderate caregiver burden was also associated with reduced HRQL, especially for social function (MSD 23.0, 95% CI: 18.5 to 27.6) and role emotional (MSD 27.8, 95%CI: 19.9 to 35.7).

CONCLUSIONS

The study indicates that a high caregiver burden is associated with worse health effects for the family caregiver of oesophageal cancer survivors.

Exercise-based dysphagia rehabilitation for adults with oesophageal cancer: a systematic review

BACKGROUND

Dysphagia is prevalent in oesophageal cancer with significant clinical and psychosocial complications. The purpose of this study was i) to examine the impact of exercise-based dysphagia rehabilitation on clinical and quality of life outcomes in this population and ii) to identify key rehabilitation components that may inform future research in this area.

METHODS

Randomised control trials (RCT), non-RCTs, cohort studies and case series were included. 10 databases (CINAHL Complete, MEDLINE, EMBASE, Web of Science, CENTRAL, and ProQuest Dissertations and Theses, OpenGrey, PROSPERO, RIAN and SpeechBITE), 3 clinical trial registries, and relevant conference abstracts were searched in November 2020. Two independent authors assessed articles for eligibility before completing data extraction, quality assessment using ROBINS-I and Downs and Black Checklist, followed by descriptive data analysis. The primary outcomes included oral intake, respiratory status and quality of life. All comparable outcomes were combined and discussed throughout the manuscript as primary and secondary outcomes.

RESULTS

Three single centre non-randomised control studies involving 311 participants were included. A meta-analysis could not be completed due to study heterogeneity. SLT-led post-operative dysphagia intervention led to significantly earlier start to oral intake and reduced length of post-operative hospital stay. No studies found a reduction in aspiration pneumonia rates, and no studies included patient reported or quality of life outcomes. Of the reported secondary outcomes, swallow prehabilitation resulted in significantly improved swallow efficiency following oesophageal surgery compared to the control group, and rehabilitation following surgery resulted in significantly reduced vallecular and pyriform sinus residue. The three studies were found to have 'serious' to 'critical' risk of bias.

CONCLUSIONS

This systematic review highlights a low-volume of low-quality evidence to support exercise-based dysphagia rehabilitation in adults undergoing surgery for oesophageal cancer. As dysphagia is a common symptom impacting quality of life throughout survivorship, findings will guide future research to determine if swallowing rehabilitation should be included in enhanced recovery after surgery (ERAS) programmes. This review is limited by the inclusion of non-randomised control trials and the reliance on Japanese interpretation which may have resulted in bias. The reviewed studies were all of weak design with limited data reported.

Health-related quality of life after esophagectomy in patients with esophageal cancer

Esophageal cancer is one of the malignant tumors with the poorest prognosis. Esophagectomy, which is the mainstay of curative-intent treatments, imposes excessive surgical stress on the patients, and postoperative morbidity and mortality rates after esophagectomy remain high. On the other hand, the number of survivors after esophagectomy for esophageal cancer is increasing due to recent improvements in surgical techniques and multidisciplinary treatments for this cancer. However, esophagectomy still has a great influence on the fundamental aspect of patients' lives, that is, the health-related quality of life (HR-QOL), including their physical, emotional, and social functions in the short- and long-term postoperatively. HR-QOL is a multifactorial concept used to assess the symptoms and functional changes caused by the disease itself and treatments from the patients' perspectives. Therefore, assessing the HR-QOL of patients with esophageal cancer after esophagectomy is becoming increasingly important. However, the status of HR-QOL changes after esophagectomy has not been satisfactorily evaluated, and there is no worldwide consensus as to how the postoperative HR-QOL can be improved. This review aimed to raise awareness of healthcare providers, such as surgeons and nurses, on the importance of HR-QOL in patients with esophageal cancer after curative-intent esophagectomy by providing multifaceted information concerning the short- and long-term HR-QOLs, including the status of changes and the determinants of HR-QOL after esophagectomy, and furthermore, essential points for improvement of HR-QOL after esophagectomy.

Prediction of severe reflux after oesophageal cancer surgery

INTRODUCTION

A common and burdensome consequence of oesophagectomy for cancer is reflux. This study aimed to develop a risk prediction model for postoperative reflux using variables available at the time of surgery enabling tailored preventive symptom management.

METHODS

Data were obtained from a nationwide, population-based cohort of 921 adults who underwent oesophagectomy for cancer between 2013 and 2019. Among 569 eligible patients, 383 (67%) participated in the study. Patient and clinical characteristics were retrieved from national health registries and medical records. Postoperative reflux was self-reported 1 year after surgery in the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire module for gastroesophageal symptoms. Multivariable regression models provided odds ratios (OR) with 95% confidence intervals (CI). The performance of the model was evaluated using the area under the receiver-operating characteristic curve.

RESULTS

Female sex (OR 2.24, 95% CI: 1.00-5.00), preoperative reflux (OR 2.99, 95% CI: 1.61-5.52), and preoperative body mass index ≥30 (OR 2.45, 95% CI: 1.32-4.54) increased the risk of postoperative reflux. A model based on age, sex, preoperative reflux, body mass index, chronic obstructive pulmonary disease, and ventricle substitute predicted 72% of the severe cases.

CONCLUSION

Female sex, preoperative reflux, and preoperative body mass index increased the risk of postoperative reflux. A combination of readily available patient and preoperative clinical variables showed fairly good accuracy in predicting postoperative reflux after oesophagectomy. The clinical risk prediction model may be helpful for early symptom management but needs to be externally validated before wider use.

PET Imaging and Rate of Pathologic Complete Response in Esophageal Squamous Cell Carcinoma

BACKGROUND

For locally advanced esophageal squamous cell carcinoma (ESCC), chemoradiation (ChemoRT) followed by surgery offers the best chance of cure, with a 35-50% pathologic complete response (pCR) rate. Given the morbidity of esophagectomy and the possibility of pCR with ChemoRT, a 'watch and wait' strategy has been proposed, particularly for squamous cell carcinoma. The ability to accurately predict which patients will have pCR from ChemoRT is critical in treatment decision making. This study assessed positron emission tomography (PET) in predicting pCR after neoadjuvant ChemoRT for ESCC.

METHODS

ESCC patients treated with ChemoRT followed by surgery were identified. Maximum standard uptake value (SUV), metabolic tumor volume, total lesion glycolysis, and first-order textual features of standard deviation, kurtosis and skewness were measured from PET. Univariable and multivariable generalized linear method analyses were performed. A metabolic complete response (mCR) was defined as a post-therapy PET scan with maximum SUV < 4.0.

RESULTS

Twenty-seven patients underwent ChemoRT followed by surgery, with overall pCR seen in 11 (41%) patients and radiographic mCR seen in 12 (44%) patients. Final pathology for these 12 patients revealed pCR (ypT0N0M0) in 5 (42%) patients and persistent disease in 7 (58%) patients. Univariate analysis did not reveal PET parameters predictive of pCR.

CONCLUSION

Treatment of ESCC with ChemoRT often results in a robust clinical response. Among patients with an mCR after ChemoRT, disease persistence was found in 58%. The inability of PET to predict pCR is important in the context of a 'watch and wait' strategy for ESCC treated with ChemoRT.

[Complete response after neoadjuvant therapy for esophageal cancer : Implications for surgery]

A relevant number of patients with locally advanced esophageal squamous cell carcinoma and adenocarcinoma show a locoregional complete response of the tumor in the resected material after neoadjuvant therapy with modern chemotherapy and chemoradiation protocols. Due to a high rate of perioperative morbidity and decreased long-term quality of life following esophagectomy, the current treatment algorithm with neoadjuvant therapy and post-neoadjuvant esophagectomy on principle is critically questioned. An individualized treatment algorithm with extended clinical evaluation of post-neoadjuvant remission status and esophagectomy as needed is discussed. Patients with complete remission after neoadjuvant therapy are identified in an extended restaging protocol. Cases of clinical complete remission are treated with an active surveillance concept with esophagectomy as needed, i.e. surgery only when a local tumor recurrence is detected. Retrospective cohort studies have suggested that the active surveillance concept with esophagectomy as needed does not lead to a deterioration of overall survival rates in the patient collective. European prospective randomized, controlled, noninferiority studies with an oncological endpoint are currently evaluating the possibilities of organ-preserving concepts for clinical complete remission of esophageal cancer.

Severe Reflux and Symptoms of Anxiety and Depression After Esophageal Cancer Surgery

BACKGROUND

Approximately 30% of patients suffer from severe reflux after surgery for esophageal cancer, which may serve as a continuous reminder of the cancer and catalyze fear of recurrence.

OBJECTIVE

The aim of this study was to investigate the association between severe reflux and symptoms of anxiety and depression after esophageal cancer surgery.

METHODS

This was a nationwide prospective cohort study including all Swedish patients who underwent esophageal cancer surgery between 2013 and 2018. Patients reported reflux on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire module for gastroesophageal symptoms and psychological distress on the Hospital Anxiety and Depression Scale at 1 and 2 years after surgery. Repeated-measures logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for age, sex, comorbidity, body mass index, TNM classification, neoadjuvant therapy, surgery type, postoperative complications, antireflux medication, and elevated headrest at night.

RESULTS

Among 154 included patients, 43 (28%) and 37 (24%) reported severe reflux 1 and 2 years after surgery, respectively. No association between severe reflux and anxiety (OR, 2.1; 95% CI, 0.7-6.3) or depression (OR, 1.2; 95% CI, 0.3-4.6) was found 1 year after surgery. After 2 years, there was still no association between severe reflux and anxiety (OR, 0.9; 95% CI, 0.3-2.8) or depression (OR, 1.2; 95% CI, 0.5-3.3).

CONCLUSIONS

Findings suggest that severe reflux is not associated with anxiety or depression after esophageal cancer surgery.

IMPLICATIONS FOR PRACTICE

For esophageal cancer survivors, other factors than severe reflux may be more important for the psychological recovery.

Social distancing during the COVID-19 pandemic and health-related quality of life among esophageal cancer survivors

PURPOSE

The purpose was to investigate whether social distancing during the COVID-19 pandemic reduced health-related quality of life (HRQL) in esophageal cancer patients and if so, to identify factors related to the HRQL changes.

METHODS

A prospective Swedish nationwide study of patients who undergone surgery for esophageal cancer between 2013 and 2019. Telephone interviews were conducted 5 weeks and 13 weeks after the introduction of social distancing recommendations. The participants responded to a few scales and items from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30. Regression models adjusted for potential confounders were used to examine mean score differences (MSD) with 95% confidence intervals (CI) between compliance with the recommendations and HRQL.

RESULTS

In total, 134 individuals participated in the study. At 5 weeks, a reduction in role function was seen for individuals who fully (MSD -8, 95% CI: -16 to 0) and to a large extent (MSD -19, 95% CI: -26 to -12) complied with the recommendations. Less fatigue (MSD 9, 95% CI: 3-15) was also detected for this group. Being female, elderly, having comorbidities, living in a region with higher COVID-19 incidence, living in a villa, and being considered as an at-risk person were related to changes in role function. At 13 weeks, reductions in role function continued for those who fully complied with the recommendations (MSD -10, 95% CI: -19 to -1), but the risk variables were of less importance. Improvements in fatigue were no longer detected. Global quality of life, emotional function, or insomnia remained stable over time.

CONCLUSIONS

This study indicates that individuals who undergone surgery for esophageal cancer and fully or to a large extent complied with the recommendations experienced reductions in role function, but not in global quality of life or emotional function, during the COVID-19 pandemic.

Health-related quality of life following total minimally invasive, hybrid minimally invasive or open oesophagectomy: a population-based cohort study

BACKGROUND

Minimally invasive oesophagectomy has been shown to reduce the risk of pulmonary complications compared with open oesophagectomy, but the effects on health-related quality of life (HRQoL) and oesophageal cancer survivorship remain unclear. The aim of this study was to assess the longitudinal effects of minimally invasive compared with open oesophagectomy for cancer on HRQoL.

METHODS

All patients who had surgery for oesophageal cancer in Sweden from January 2013 to April 2018 were identified. The exposure was total or hybrid minimally invasive oesophagectomy, compared with open surgery. The study outcome was HRQoL, evaluated by means of the European Organisation for Research and Treatment of Cancer questionnaires QLQ-C30 and QLQ-OG25 at 1 and 2 years after surgery. Mean differences and 95 per cent confidence intervals were adjusted for confounders.

RESULTS

Of the 246 patients recruited, 153 underwent minimally invasive oesophagectomy, of which 75 were hybrid minimally invasive and 78 were total minimally invasive procedures. After adjustment for age, sex, Charlson Co-morbidity Index score, pathological tumour stage and neoadjuvant therapy, there were no clinically and statistically significant differences in overall or disease-specific HRQoL after oesophagectomy between hybrid minimally invasive and total minimally invasive surgical technique versus open surgery.

CONCLUSION

In this population-based nationwide Swedish study, longitudinal HRQoL after minimally invasive oesophagectomy was similar to that of the open surgical approach.

Postneoadjuvant surveillance and surgery as needed compared with postneoadjuvant surgery on principle in multimodal treatment for oesophageal cancer: a scoping review protocol

INTRODUCTION

In current medical practice of curative treatment for non-metastatic oesophageal cancer, surgery on principle is carried out by oesophagectomy after neoadjuvant treatment. However, oesophagectomy is often associated with postoperative morbidity and mortality. Taking into account that modern neoadjuvant therapy is effective and many of patients show no vital tumour cells in the operative specimens, we aim to perform a scoping review as part of the development phase for a prospectively planned multicentre randomised controlled trial investigating 'surgery as needed vs surgery on principle in patients with postneoadjuvant complete response of oesophageal cancer' (Prospective trial registration number DRKS00022801). This scoping approach will allow us to finally define and/or adapt the research question including the design and methodology of the randomised controlled trial taking into account the findings for example, research gaps and/or pitfalls in the currently available study pool addressing this or very similar questions.

METHODS AND ANALYSIS

To identify relevant research, we will conduct searches in the electronic databases Medline, Web of Science Core Collection, Cochrane Library and Science Direct. We will also check references of relevant studies and perform a cited reference research (forward citation tracking). Titles and abstracts of the records identified by the searches will be screened and full texts of all potentially relevant articles will be obtained. We will consider randomised trials and non-randomised controlled studies. Data extraction tables will be set up, including study and patients' characteristics, aim of study and reported outcomes. We will summarise the data using tables and figures (eg, bubble plots) to present the research landscape and to describe potential clusters and/or gaps to support the planning of a randomised trial in this patient population.

ETHICS AND DISSEMINATION

Ethical approval is not required for this scoping review. Study findings will be shared by publication in a peer-reviewed journal and by presentation to key stakeholders on scientific meetings.

Severe reflux, sleep disturbances, and health-related quality of life after esophageal cancer surgery

PURPOSE

Esophagectomy for cancer is an extensive procedure often followed by severe complications. This study investigated whether patients with severe symptoms of reflux are more likely to have sleep disturbances and reduced health-related quality of life (HRQL) after esophagectomy.

METHODS

This Swedish nationwide prospective cohort study encompassed all patients who had undergone esophagectomy for cancer between 2013 and 2018. One year after surgery, the patients responded to three questionnaires on reflux (EORTC QLQOG25), sleep disturbances (KSQ), and HRQL (EORTC QLQ-C30). Multivariable logistic regression provided odds ratios (OR) with 95% confidence intervals (CI) for sleep disturbance/reduced HRQL between patients with and without reflux, adjusted for potential confounders.

RESULTS

Among 241 esophagectomy patients, 66 (27%) reported severe reflux. Patients with reflux had an increased risk of sleep disturbances (OR 2.3, 95% CI: 1.3-4.3) compared to patients without reflux. More specifically, these patients were more likely to suffer from poor sleep quality (OR 4.9, 95% CI: 1.9-12.4). Patients with reflux and sleep disturbances reported reductions in global quality of life, role function, emotional function, social function, and more symptoms in all scales, except for dyspnea.

CONCLUSIONS

This study suggests that patients with severe symptoms of reflux after esophagectomy have an increased risk of sleep disturbances and poor sleep quality, which in turn are associated with reduced HRQL.

IMPLICATIONS FOR CANCER SURVIVORS

Alleviating reflux after oesophageal cancer surgery is important, since this common symptom might reduce HRQL and well-being.

Post-Neoadjuvant Surveillance and Surgery as Needed Compared with Post-Neoadjuvant Surgery on Principle in Multimodal Treatment for Esophageal Cancer: A Scoping Review

Simple Summary

A substantial fraction of patients with esophageal cancer show post-neoadjuvant pathological complete response (pCR). Principal esophagectomy after neoadjuvant treatment is the standard of care for all patients, including those with pCR. Surveillance and surgery as needed may be a treatment alternative for these patients. We performed a scoping review and described all relevant clinical studies addressing these two treatment approaches. We identified three completed randomized controlled trials (RCTs) including 468 participants, three planned/ongoing RCTs with a planned sample size of 752 participants, one non-randomized controlled study with 53 participants, ten retrospective cohort studies (2228 participants) and one survey on patients’ preferences (100 participants). The current scoping review reveals that although surveillance and surgery as needed has been investigated within different study designs, the available study pool show methodological limitations and clinical results are heterogeneous. A thoroughly planned RCT considering these limitations will be of great importance to provide these patients with the best treatment.

Abstract

Background: A substantial fraction of patients with esophageal cancer show post-neoadjuvant pathological complete response (pCR). Principal esophagectomy after neoadjuvant treatment is the standard of care for all patients, although surveillance and surgery as needed in case of local recurrence may be a treatment alternative for patients with complete response (CR). Methods: We performed a scoping review to describe key characteristics of relevant clinical studies including adults with non-metastatic esophageal cancer receiving multimodal treatment. Until September 2020, relevant studies were identified through systematic searches in the bibliographic databases Medline, Web of Science, Cochrane Library, Science Direct, ClinicalTrials, the German study register, and the WHO registry platform. Results: In total, three completed randomized controlled trials (RCTs, with 468 participants), three planned/ongoing RCTs (with a planned sample size of 752 participants), one non-randomized controlled study (NRS, with 53 participants), ten retrospective cohort studies (with 2228 participants), and one survey on patients’ preferences (with 100 participants) were identified. All studies applied neoadjuvant chemoradiation protocols. None of the studies examined neoadjuvant chemotherapeutic protocols. Studies investigated patient populations with esophageal squamous cell carcinoma, adenocarcinoma, and mixed cohorts. Important outcomes reported were overall, disease-free and local recurrence-free survival. Limitations of the currently available study pool include heterogeneous chemoradiation protocols, a lack of modern neoadjuvant treatment protocols in RCTs, short follow-up times, the use of heterogeneous diagnostic methods, and different definitions of clinical CR. Conclusion: Although post-neoadjuvant surveillance and surgery as needed compared with post-neoadjuvant surgery on principle has been investigated within different study designs, the currently available results are based on a wide variation of diagnostic tools to identify patients with pCR, short follow-up times, small sample sizes, and variations in therapeutic procedures. A thoroughly planned RCT considering the limitations in the currently available literature will be of great importance to provide patients with CR with the best and less harmful treatment.

Minimal Invasive Esophagectomy-a New Dawn of EsophagealSurgery

Surgery is the mainstay of esophageal cancer. However, esophagectomy is a major surgical trauma on a patient with high morbidity and mortality. The intent of minimally invasive esophagectomy (MIE) is to decrease the degree of surgical trauma and perioperative morbidity associated with open surgery, and provide faster recovery and shorter hospital stay with the equivalent oncological outcome. It also allows for lesser pulmonary morbidity, less blood loss, less pain, and a better quality of life. MIE is safe and effective but has a steep learning curve with high technical expertise. Recently, it is increasingly accepted and adopted all over the globe. In this article, we discuss the safety, efficacy, short-term, and oncological outcomes of thoracoscopic- and laparoscopic-assisted minimally invasive esophagectomy and robotic surgery compared with open esophagectomy with a special focus on the Indian perspective.

Long-Term, Health-Related Quality of Life after Open and Robot-Assisted Ivor-Lewis Procedures-A Propensity Score-Matched Study

Esophagectomies are among the most invasive surgical procedures that highly influence health-related quality of life (HRQoL). Recent improvements have helped to achieve longer survival. Therefore, long-term postoperative HRQoL needs to be emphasized in addition to classic criterions like morbidity and mortality. We aimed to compare short and long-term HRQoL after open transthoracic esophagectomies (OTEs) and robotic-assisted minimally invasive esophagectomies (RAMIEs) in patients suffering from esophageal adenocarcinoma. Prospectively collected HRQoL-data (from the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire-C30 (EORTC QLQ-C30)) were correlated with clinical courses. Only patients suffering from minor postoperative complications (Clavien-Dindo Classification of < 2) after R0 Ivor-Lewis-procedures were included. Age, sex, body mass index (BMI), American Society of Anesthesiologists physical status-score (ASA-score), tumor stage, and perioperative therapy were used for propensity score matching (PSM). Twelve RAMIE and 29 OTE patients met the inclusion criteria. RAMIE patients reported significantly better emotional and social function while suffering from significantly less pain and less physical impairment four months after surgery. The long-term follow up confirmed the results. Long-term postoperative HRQoL and self-perception partly exceeded the levels of the healthy reference population. Minor operative trauma by robotic approaches resulted in significantly reduced physical impairments while improving HRQoL and self-perception, especially in the long-term. However, further long-term results are warranted to confirm this positive trend.

Minimally Invasive Ivor Lewis Esophagectomy with Linear Stapled Anastomosis Associated with Low Leak and Stricture Rates

BACKGROUND

Minimally invasive foregut surgery is increasingly performed for both benign and malignant diseases. We present a retrospective series of patients who underwent minimally invasive Ivor Lewis esophagectomy (MIE) with linear stapled anastomosis performed at two centers in the USA, with a focus on evaluating leak and stricture rates.

METHODS

Patients treated from 2007 to 2018 were included, and data on demographics, oncologic treatment, pathology, and outcomes were analyzed. The surgical technique utilized laparoscopic and thoracoscopic access, with an intrathoracic esophagogastric anastomosis using a 6-cm linear stapled side-to-side technique.

RESULTS

A total of 124 patients were included and 114 resections (91.9%) were completed in a minimally invasive fashion with a 6-cm linear stapled side-to-side anastomosis. Patients were predominantly male (90.7%) with a median age of 66.0 years and body mass index of 28.8 kg/m². Of 121 patients with malignancy, negative margins were obtained in 94.3% and median lymph node yield was 15 (IQR 12-22). In the intention to treat analysis, median operative time was 463 min (IQR 403-515), blood loss was 150 mL (IQR 100-200), and length of stay was 8 days (IQR 7-11). Postoperative complications were experienced by 64 patients (51.6%) including respiratory failure in 14 (11.3%) and pneumonia in 12 (9.7%). In patients who successfully underwent a 6-cm stapled side-to-side anastomosis, anastomotic leaks occurred in 6 patients (5.1%) without need for operative intervention, and anastomotic strictures occurred in 6 patients (5.1%) requiring endoscopic management.

CONCLUSIONS

Ivor Lewis MIE with a 6-cm linear stapled anastomosis can be completed with a high technical success rate, and low rates of anastomotic leak and stricture.

Patient-reported outcomes 1 year after oesophageal cancer surgery

Purpose: To improve survivorship in patients who have undergone curatively intended treatment for oesophageal cancer, we aimed to identify key targets for future patient-reported outcomes research.Methods: This nationwide Swedish prospective cohort study enrolled patients between 2014 and 2019 who had undergone surgical resection for oesophageal cancer 1 year earlier. Eight well-validated patient-reported outcome measures, including health-related quality of life, psychological status and sleep, were presented as proportions and mean scores (MS) with 95% confidence intervals (CIs).Results: Among 281 participants, approximately half of the patients reported problems associated with food intake such as eating restrictions (49%) and food aversion (47%). Other common problems were sleep (51%), fatigue (41%) and anxiety (36%). Fewer patients suffered from financial difficulties (9%), trouble swallowing saliva (4%) and hair loss (7%). However, these problems were perceived as highly burdensome on an individual level.Conclusions: This nationwide, population-based study indicates that symptom burden is high in oesophageal cancer survivors 1 year after surgery. The most common problems are associated with food intake, sleep, fatigue and anxiety. However, less frequent symptoms were sometimes more debilitating for the individual patient.

Treatment of early stage (T1) esophageal adenocarcinoma: Personalizing the best therapy choice

Esophagectomy is considered the primary form of management for esophageal adenocarcinoma (EAC); however, the surgery is associated with high rates of morbidity and mortality. For patients with early-stage EAC, endoscopic resection (ER) presents a potential curative treatment option that is less invasive and carries fewer risks procedure related risks, but it is associated with higher rates of cancer recurrence following the procedure. For some patients, age and comorbidities may prevent them from having esophagectomy as a treatment option, while other patients may be operative candidates but do not wish to undergo esophagectomy for a variety of reasons related to their values and preferences. Furthermore, while anxiety of cancer recurrence following ER may significantly diminish a patient’s quality of life (QOL), so might the morbidity surrounding esophagectomy. In addition to considering health status, patient preferences, and impacts on QOL, physicians and patients must also consider what treatments would be both beneficial and available to the patient, considering esophagectomy methods-minimally invasive vs open-or the use of chemoradiotherapy in addition to ER. Our article reviews and summarizes available treatment options for patients with early EAC and their potential effects on the health and wellbeing of patients based on the current data. We conclude with a request for more research of available options for early EAC patients, the conditions that determine when each option should be employed, and their effects not only on patient health but also QOL.

Change in tongue pressure and the related factors after esophagectomy: a short-term, longitudinal study

BACKGROUND

Dysphagia is a prominent symptom after esophagectomy and may cause aspiration pneumonia. Swallowing evaluation after esophagectomy can predict and help control the incidence of postoperative pneumonia. The aim of this study was to clarify whether the change in tongue pressure was associated with any related factor and postoperative dysphagia/pneumonia in patients with esophageal cancer after esophagectomy.

METHODS

Fifty-nine inpatients (41 males and 18 females; 33-77 years old) who underwent esophagectomy participated in this study. Measurement of tongue pressure and the repetitive saliva swallowing test (RSST) was performed before esophagectomy (baseline) and at 2 weeks postoperatively. The general data were collected from patients' medical records, including sex, age, type of cancer, cancer stage, location of cancer, operative approach, history of previous chemotherapy, surgical duration, amount of bleeding during surgery, incidences of postoperative complications, intubation period, period between surgery and initiation of oral alimentation, and intensive care unit (ICU) stay, blood chemical analysis, and lifestyle.

RESULTS

Tongue pressure decreased significantly after esophagectomy (p = 0.011). The decrease of tongue pressure was significantly associated with length of ICU stay and preoperative tongue pressure on multiple regression analysis (p < 0.05). The decrease of tongue pressure in the RSST < 3 or postoperative pneumonia (+) group was significantly greater than in the RSST ≥ 3 (p = 0.003) or pneumonia (-) group (p = 0.021).

CONCLUSIONS

The decrease in tongue pressure was significantly associated with the length of ICU stay, preoperative tongue pressure, and the incidence of dysphagia and pneumonia among inpatient after esophagectomy.

Oesophagectomy: The expanding role of minimally invasive surgery in oesophageal cancer

Historically, open oesophagectomy was the gold standard for oesophageal cancer surgery. This was associated with a relatively higher morbidity. In the last two decades, we have seen significant improvements in short and long term outcomes due to centralisation of oesophagectomy, multidisciplinary approach, enhanced recovery after surgery programmes, neoadjuvant treatments and advances in minimally invasive oesophagectomy (MIO) techniques. MIO has significantly reduced postoperative morbidity and improved functional recovery, while maintaining comparable long-term oncological outcomes. MIO is technically demanding, and requires a long learning curve. However, it has been proven to be safe and successful in expert centres. This is a review on the current role of MIO in the management of oesophageal cancer.

Endoscopic Resection in the Esophagus

The article is a review of the principles behind endoscopic resection of esophageal dysplasia and early cancers. The techniques of endoscopic mucosal resection and endoscopic submucosal dissection are reviewed, and the supporting literature compared. Endoscopic resection is compared with esophagectomy for the management of these lesions and current areas of controversy with regard to T1b lesions and gastroesophageal reflux following resection are addressed.

Presentation of oropharyngeal dysphagia and rehabilitative intervention following esophagectomy: a systematic review

No study has systematically reviewed the evidence on presentation of oropharyngeal dysphagia and swallowing rehabilitation following esophagectomy. The purposes of this systematic review are to 1) qualitatively synthesize the current findings on oropharyngeal swallowing abnormalities identified by instrumental swallowing evaluations, 2) describe the reported health-related outcomes in relation to swallowing abnormality following esophagectomy, and 3) examine the efficacy of reported rehabilitative interventions for oropharyngeal dysphagia in patients who underwent esophagectomy. Publications were searched using five electronic databases. No language or publication date restrictions were imposed. Two authors performed a blind review for published or unpublished studies that reported swallowing biomechanics and dysphagic symptoms using instrumental evaluation of swallowing, specifically the videofluoroscopic swallowing study and fiberoptic endoscopic evaluation of swallowing, and/or health-related outcomes in relation to swallowing abnormalities, and/or therapeutic interventions for oropharyngeal dysphagia following esophagectomy. Twelve studies out of 2,193 studies including 458 patients met the inclusion criteria. Reported abnormal swallowing biomechanics included vocal fold immobility, delayed onset of swallowing, reduced hyolaryngeal elevation, and reduced opening of the upper esophageal sphincter. Aspiration (0-81%) and pharyngeal residue (22-100%) were prevalent. Those abnormal swallowing biomechanics and swallowing symptoms were commonly reported following both transhiatal and transthoracic esophagectomy. Pneumonia presented in 5-25% of the study patients. One quasi-experimental study examined the effectiveness of swallowing exercises for postoperative oropharyngeal dysphagia; three case series reported a benefit of the chin-tuck maneuver in reducing aspiration and residue. This review revealed distinct swallowing impairments and increased pneumonia risks following esophagectomy. This review also found that evidence on the efficacy of therapeutic interventions was limited. Future studies are warranted to develop effective rehabilitative interventions for postesophagectomy patients with oropharyngeal dysphagia.

[Effects of minimally invasive versus open esophagectomy on circulating tumor cells in patients with esophageal cancer]

OBJECTIVE

To investigate the effects of minimally invasive esophagectomy (MIE) and open esophagectomy (OE) on the level of circulating tumor cells (CTCs) in patients with esophageal cancer (EC).

METHODS

A total of 73 patients with EC undergoing MIE (n=38) or OE (n=35) in our department between October, 2015 and October, 2017 were enrolled, with 10 patients with benign esophagus disease and 10 healthy volunteers as controls. The levels of CTCs in the peripheral blood of the participants were detected using CanPatrol^TM technique and analyzed for their association with the operation methods and perioperative complications.

RESULTS

CTCs were detected in 60.3% (44/73) of the EC patients but in none of the control subjects. CTC level after the surgery was significantly higher than that during the surgery, and CTC level during the surgery was significantly higher than that before surgery (P<0.001). The preoperative and intra-operative CTC levels were not significantly different between MIE and OE groups (P>0.05), but the postoperative CTC level was significantly lower in MIE group than in OE group, and postoperative increment of CTC level (from the preoperative level) was significantly lower in MIE group than in OE group (P<0.001). The total incidence of postoperative complications was significantly lower in MIE group than in OE group (28.9% vs 54.3%, P=0.023), and in both groups, CTC levels in patients with complications were significantly higher than those in patients without complications (P=0.001 and P=0.005 in MIE and OE groups, respectively).

CONCLUSION

MIE may help to reduce the number of peripheral blood CTCs early after the operation, and dynamic monitoring CTCs level assists in evaluation of the prognosis of EC patients. CTC level may serve as an indicator for monitoring the prognosis of EC.
