Meta-analysis shows clinically relevant and long-lasting deterioration in health-related quality of life after esophageal cancer surgery

What are the outcomes for long-term survivors after esophagectomy ? - Evidence from a randomized controlled trial (FFCD9901)

BACKGROUND

Little is known regarding long-term outcomes of survivors beyond 5 years after esophagectomy. This study assesses oncological outcomes of long-term survivors of esophageal cancer.

METHODS

Data is derived from a multi-center randomized controlled trial comparing neoadjuvant chemoradiotherapy (NCRT) and surgery to surgery alone for clinically stage I and II esophageal cancers (FFCD9901). Only patients undergoing esophagectomy were included in this study. Clinicopathological variables of 5-year survivors were analyzed. Multivariate logistic regression analysis identified factors predictive of death prior to 5 years. Patterns of disease recurrence and second primary tumor development were established.

RESULTS

From June 2000 until June 2009, 195 patients from 30 French centers were randomly assigned to NCRT followed by surgery or surgery alone. Of 170 patients who underwent esophagectomy, 70 patients were alive at 5 years - an overall 5-year survival of 41.2 %. In logistic regression multivariate analysis, WHO performance status of ≥1 (p = 0.045), advanced pT category (p = 0.030) and post-operative complications (p = 0.047) predicted death prior to 5 years. Twenty patients died after the 5-year time point, 9 of these due to progression of their esophageal cancer. Nineteen patients developed a second primary malignancy, of whom 14 developed either a head and neck or lung cancers.

CONCLUSIONS

Being alive 5 years after esophagectomy does not equate to cure. In clinically staged early disease, a distinct group of patients develop disease recurrence later than 5 years from treatment. Development of a second primary cancer in this population poses a clinical threat. Surveillance protocols should be adapted accordingly.

Longitudinal patient-reported outcomes after minimally invasive McKeown esophagectomy for patients with esophageal squamous cell carcinoma

PURPOSE

Surgery for esophageal squamous cell carcinoma (ESCC) is characterized by a poor prognosis and high complication rate, resulting in a heavy symptom burden and poor health-related quality of life (QOL). We evaluated longitudinal patient-reported outcomes (PROs) to analyze the correlations between symptoms and QOL and their changing characteristics during postoperative rehabilitation.

METHODS

We investigated patients with ESCC who underwent minimally invasive McKeown esophagectomy at Sichuan Cancer Hospital between April 2019 and December 2019. Longitudinal data of the clinical characteristics and PROs were collected. The MD Anderson Symptom Inventory and European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires were used to assess symptoms and QOL and compare the trajectories of PROs during the investigation.

RESULTS

A total of 244 patients with ESCC were enrolled in this study. Regarding QOL, role and emotional functions returned to baseline at 1 month after surgery, and cognitive and social functions returned to baseline at 3 months after surgery. However, physical function and global QOL did not return to baseline at 1 year after surgery. At 7 days and 1, 3, 6, and 12 months after surgery, the main symptoms of the patients were negatively correlated with physical, role, emotional, cognitive, and social functions and the overall health status (P < 0.05).

CONCLUSION

Patients with ESCC experience reduced health-related QOL and persisting symptoms after minimally invasive McKeown esophagectomy, but a recovery trend was observed within 1 month. The long-term QOL after esophagectomy is acceptable.

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.

Comparison of two different methods for lymphadenectomy along the left recurrent laryngeal nerve by minimally invasive esophagectomy in patients with esophageal squamous cell carcinoma: a prospective randomized trial

BACKGROUND

Lymph nodes along the left recurrent laryngeal nerve (LRLN) is thought to be highly involved in esophageal cancer. Given the unique anatomical positioning of the nerve, performing lymphadenectomy in this region requires advanced techniques within limited working space. Meanwhile, high incidence of morbidity and mortality is associated with lymphadenectomy. Although several methods have been applied to reduce the technical requirement and the incidence of postoperative complication, the optimal method remains controversial.

METHODS

This study was a single-center, prospective, randomized trial to investigate the utility of lymphadenectomy along the LRLN during the minimally invasive esophagectomy in esophageal squamous cell carcinoma patients by comparing the surgical outcome, postoperative complication, survival rate, and quality of life (QoL) between the retraction method (RM) and the suspension method (SM) in patients with esophageal cancer from June 2018 to November 2020. QoL was assessed according to questionnaire: EQ-5D-5L.

RESULTS

Of 94 patients were enrolled and randomized allocated to RM and SM group equally. Characteristics did not differ between groups. The duration of lymph node dissection along LRLN was significant longer in SM group ( P <0.001). No difference was observed about postoperative complications. One of in-hospital death was occurred in each group ( P >0.999). Patients in neither of groups exhibiting difference about 3-year disease-free survival rate ( P =0.180) and overall survival rate ( P =0.430). No difference was observed in postoperative QoL between groups at different time points (all, P >0.05).

CONCLUSION

Both methods of lymph node dissection along the LRLN during minimally invasive esophagectomy in esophageal squamous cell carcinoma patients are technically feasible and safe. The RM appears more favorable in terms of reducing surgical duration compared to the SM.

Unveiling Therapeutic Targets for Esophageal Cancer: A Comprehensive Review

Esophageal cancer is a highly aggressive and deadly disease, ranking as the sixth leading cause of cancer-related deaths worldwide. Despite advances in treatment, the prognosis remains poor. A multidisciplinary approach is crucial for achieving complete remission, with treatment options varying based on disease stage. Surgical intervention and endoscopic treatment are used for localized cancer, while systemic treatments like chemoradiotherapy and targeted drug therapy play a crucial role. Molecular markers such as HER2 and EGFR can be targeted with drugs like trastuzumab and cetuximab, and immunotherapy drugs like pembrolizumab and nivolumab show promise by targeting immune checkpoint proteins. Epigenetic modifications offer new avenues for targeted therapy. Treatment selection depends on factors like stage, tumor location, and patient health, with post-operative and rehabilitation care being essential. Early diagnosis, appropriate treatment, and supportive care are key to improving outcomes. Continued research is needed to develop effective targeted drugs with minimal side effects. This review serves as a valuable resource for clinicians and researchers dedicated to enhancing esophageal cancer treatment outcomes.

Quality of Life in Patients Undergoing Surgery for Upper GI Malignancies

Upper gastrointestinal (GI) conditions vastly affect each individual's physical, social, and emotional status. The decision-making process by the medical personnel about these patients is currently based on a patient's life quality evaluation scale, HRQL scales. By utilizing HRQL scales, a better understanding of the various surgical and non-surgical treatment options, as well as their long-term consequences, can be achieved. In our study, an organ-based approach is used in an attempt to examine and characterized the effect of upper GI surgery on HRQL. Therefore, HRQL scales' function as a prognostic tool is useful, and the need for future research, the creation of valid training programs, and modern guidelines is highlighted.

European Head and Neck Society recommendations for head and neck cancer survivorship care

Survivors of head and neck cancer can experience long-term consequences of the cancer and subsequent treatments even after the cancer has resolved. Increasingly clinicians are aware of the social, psychological, financial, and emotional impacts of these cancers, in addition to the support required for the physical symptoms. This review provides recommendations on the long-term management and support required for survivors of head and neck cancer in the European healthcare setting.

A novel web-based dynamic nomogram for recurrent laryngeal nerve lymph node metastasis in esophageal squamous cell carcinoma

Background

Patients with esophageal squamous cell carcinoma (ESCC) are liable to develop recurrent laryngeal nerve (RLN) lymph node metastasis (LNM). We aimed to assess the predictive value of the long diameter (LD) and short diameter (SD) of RLN lymph node (LN) and construct a web-based dynamic nomogram for RLN LNM prediction.

Methods

We reviewed 186 ESCC patients who underwent RLN LN dissection from January 2016 to December 2018 in the Affiliated Hospital of North Sichuan Medical College. Risk factors for left and right RLN LNM were determined by univariate and multivariate analyses. A web-based dynamic nomogram was constructed by using logistic regression. The performance was assessed by the area under the curve (AUC) and Brier score. Models were internally validated by performing five-fold cross-validation.

Results

Patients who underwent left and right RLN LN dissection were categorized as left cohort (n = 132) and right cohort (n = 159), with RLN LNM rates of 15.9% (21/132) and 21.4% (34/159), respectively. The AUCs of the LD (SD) of RLN LN were 0.663 (0.688) in the left cohort and 0.696 (0.705) in the right cohort. The multivariate analysis showed that age, the SD of RLN LN, and clinical T stage were significant risk factors for left RLN LNM (all P < 0.05), while tumor location, the SD of RLN LN, and clinical T stage were significant risk factors for right RLN LNM (all P < 0.05). The dynamic nomograms showed reliable performance after five-fold cross-validation [(left (right), mean AUC: 0.814, range: 0.614–0.891 (0.775, range: 0.084–0.126); mean Brier score: 0.103, range: 0.084–0.126 (0.145, range: 0.105–0.206)], available at https://mpthtw.shinyapps.io/leftnomo/ and https://mpthtw.shinyapps.io/rightnomo/.

Conclusion

The LD and SD of RLN LN are inadequate to predict RLN LNM accurately, but online dynamic nomograms by combined risk factors show better prediction performance and convenient clinical application.

The Trajectory of Cancer-Related Fatigue and Its Associating Factors in Patients with Esophageal Cancer Receiving Treatments: A Prospective Longitudinal Study

BACKGROUND

Cancer-related fatigue (CRF) is the most distressing symptom in the overall cancer population. For patients with esophageal cancer, CRF may even be harder to predict and control due to its complicated and prolonged treatment. Moreover, communication difficulties due to disease progression or treatment may further diminish esophageal cancer patients' ability to communicate about CRF. However, little research has addressed the trajectory and associating factors of CRF in this population, especially during the active treatment phase. The purpose of this study was (1) to evaluate and compare the level of CRF at three time points, namely before treatment, a month after concurrent chemoradiotherapy (CCRT), and a week after surgery, and (2) to identify associated factors of CRF.

METHODS

This prospective cohort study used a questionnaire to evaluate esophageal cancer patients' CRF at three time points. Repeated measures ANOVA and linear regression were used to analyze the data.

RESULTS

This study included 73 participants. The severity of all CRF aspects intensified significantly over the course of treatment, reaching the highest level after surgery (P < 0.001). Worries of physician invalidation at baseline (P < 0.05) and marital status associated with CRF after CCRT and after surgery.

CONCLUSIONS

This is the first study to demonstrate the relationship between CRF and physician invalidation. Clinicians must be aware of the intensifying trend of CRF and provide timely intervention when caring for patients with esophageal cancer during cancer treatment. Reducing the worries of physician invalidation may alleviate CRF.

Symptoms, problems and quality of life in patients newly diagnosed with oesophageal and gastric cancer - a comparative study of treatment strategy

Background

Patients with oesophageal and gastric cancer have a low likelihood of being cured and suffer from a broad spectrum of symptoms and problems that negatively affect their quality-of-life (QOL). Although the majority (67–75%) of patients at the time of diagnosis suffer from an incurable disease, research has primarily focused on the pre- and postoperative phase among patients treated with curative intent, with little attention to symptoms and problems in the diagnostic phase, especially in those who cannot be offered a cure.

Methods

In this cross-sectional study 158 patients newly diagnosed with oesophageal and gastric cancer visiting the surgical outpatient department for a preplanned care visit were included consecutively during 2018–2020. The validated instruments QLQ-C30 and QLQ-OG25, developed by the European Organization for Research and Treatment of Cancer (EORTC), and selected items from the Integrated Patient Outcome Scale (IPOS) were used to assess QOL, symptoms and problems. Differences between patients with a curative and a palliative treatment strategy were analysed using t-test and Mann–Whitney U test. The QLQ-C30 and QLQ-OG25 scores were compared to published reference data on the general Swedish population.

Results

Among all, the QOL was markedly lower, compared with general Swedish population (mean ± SD, 55.9 ± 24.7 vs 76.4 ± 22.8, p < 0.001). Compared to general population, the patients had significant impairment in all QOL aspects, particularly for role and emotional functioning and for symptoms such as eating-related problems, fatigue, insomnia and dyspnea. Majority of patients also reported severe anxiety among family and friends. Among patients with oesophageal cancer those with a palliative treatment strategy, compared with curative strategy, reported significantly lower QOL (mean ± SD, 50.8 ± 28.6 vs 62.0 ± 22.9 p = 0.030), physical (65.5 ± 22.6 vs 83.9 ± 16.5, p < 0.001) and role functioning (55.7 ± 36.6 vs 73.9 ± 33.3, p = 0.012), and a higher burden of several symptoms and problems. No significant differences between treatment groups were shown among patients with gastric cancer.

Conclusions

Patients newly diagnosed with oesophageal and gastric cancer, and especially those with incurable oesophageal cancer, have a severely affected QOL and several burdensome symptoms and problems. To better address patients’ needs, it seems important to integrate a palliative approach into oesophageal and gastric cancer care.

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.

Health-related quality of life one year after the diagnosis of oesophageal cancer: a population-based study from the Swedish National Registry for Oesophageal and Gastric Cancer

BACKGROUND

Population-based patient reported outcome data in oesophageal cancer are rare. The main purpose of this study was to describe health-related quality of life (HRQOL) 1 year after the diagnosis of oesophageal cancer, comparing subgroups of curatively and palliatively managed patients.

METHODS

This is a nationwide population-based cohort study, based on the Swedish National Registry for Oesophageal and Gastric Cancer (NREV) with prospectively registered data, including HRQOL instruments from the European Organisation for Research and Treatment of Cancer including the core and disease specific questionnaires (EORTC QLQ-C30 and QLQ-OG25). Patients diagnosed with oesophageal cancer between 2009 and 2016 and with complete HRQOL data at 1 year follow-up were included. HRQOL of included patients was compared to a reference population matched by age and gender to to a previous cohort of unselected Swedish oesophageal cancer patients. Linear regression was performed to calculate mean scores with 95% confidence intervals (CI) and adjusted linear regression analysis was used to calculate mean score differences (MD) with 95% CI.

RESULTS

A total of 1156 patients were included. Functions and global health/quality of life were lower in both the curative and palliative cohorts compared to the reference population. Both curatively and palliatively managed patients reported a severe symptom burden compared to the reference population. Patients who underwent surgery reported more problems with diarrhoea compared to those treated with definitive chemoradiotherapy (dCRT) (MD -14; 95% CI - 20 to - 8). Dysphagia was more common in patiens treated with dCRT compared to surgically treated patients (MD 11; 95% CI 4 to 18). Those with palliative intent due to advanced tumour stage reported more problems with dysphagia compared to those with palliative intent due to frailty (MD -18; 95% CI - 33 to - 3).

CONCLUSIONS

One year after diagnosis both curative and palliative intent patients reported low function scores and severe symptoms. Dysphagia, choking, and other eating related problems were more pronounced in palliatively managed patients and in the curative intent patients treated with dCRT.

Surgical Therapy of Esophageal Adenocarcinoma-Current Standards and Future Perspectives

Transthoracic esophagectomy is currently the predominant curative treatment option for resectable esophageal adenocarcinoma. The majority of carcinomas present as locally advanced tumors requiring multimodal strategies with either neoadjuvant chemoradiotherapy or perioperative chemotherapy alone. Minimally invasive, including robotic, techniques are increasingly applied with a broad spectrum of technical variations existing for the oncological resection as well as gastric reconstruction. At the present, intrathoracic esophagogastrostomy is the preferred technique of reconstruction (Ivor Lewis esophagectomy). With standardized surgical procedures, a complete resection of the primary tumor can be achieved in almost 95% of patients. Even in expert centers, postoperative morbidity remains high, with an overall complication rate of 50-60%, whereas 30- and 90-day mortality are reported to be <2% and <6%, respectively. Due to the complexity of transthoracic esophagetomy and its associated morbidity, esophageal surgery is recommended to be performed in specialized centers with an appropriate caseload yet to be defined. In order to reduce postoperative morbidity, the selection of patients, preoperative rehabilitation and postoperative fast-track concepts are feasible strategies of perioperative management. Future directives aim to further centralize esophageal services, to individualize surgical treatment for high-risk patients and to implement intraoperative imaging modalities modifying the oncological extent of resection and facilitating surgical reconstruction.

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.

A nomogram for predicting lymph node metastasis in superficial esophageal squamous cell carcinoma

Superficial esophageal squamous cell carcinoma (SESCC) is defined as carcinoma with mucosal or submucosal invasion, regardless of regional lymph node metastasis (LNM). The lymph node status is not only a key factor to determine the training strategy, but also the most important prognostic factor in esophageal cancer. In this study, we establish a clinical nomogram for predicting LNM in patients with SESCC. A predictive model was established based on the training cohort composed of 711 patients who underwent esophagectomy for SESCC from December 2009 to June 2018. A prospective cohort of 203 patients from June 2018 to January 2019 was used for validation. Favorable calibration and well-fitted decision curve analysis were conducted and good discrimination was observed (concordance index [C-index], 0.860; 95% confidence interval [CI], 0.825-0.894) through internal validation. The external validation cohort presented good discrimination (C-index, 0.916; 95% CI, 0.860-0.971). This model may facilitate the prediction of LNM in patients with SESCCs.

Use of PD-1 and PD-L1 inhibitors after first-line therapy in esophageal cancer patients in the US

INTRODUCTION

Esophageal cancer (EC) makes up 3.2% of all cancers but ranks sixth among cancer-related deaths worldwide. This real-world analysis determined the use of PD-1/PD-L1 (PD[L]1) inhibitors in EC patients after receiving first-line therapy.

METHODS

Newly diagnosed EC patients initiating first-line treatment were identified in the IBM MarketScan administrative claims databases during the study period (1 May 2015 to 31 October 2020) using ICD-9/ICD-10 codes. Patients were assigned to either the chemotherapy only, radiation only, chemotherapy plus radiation (chemoradiation), or esophageal transhiatal/transthoracic surgery cohorts.

RESULTS

7276 EC patients started first-line therapy (chemotherapy only = 2502, radiation only = 3355, chemoradiation = 1180, surgery = 239). The average age at diagnosis was 62 years and 23% were female. The median time from start of first-line therapy to utilization of a PD(L)1 inhibitor was 259 days. Pembrolizumab (72%) was the most frequently used PD(L)1 inhibitor across the three cohorts, followed by nivolumab (25%). Furthermore, the number of patients receiving a PD(L)1 inhibitor increased each year with the majority (73%) of use occurring between 2018 and 2020.

DISCUSSION

Findings from this real-world study suggest that PD(L)1 inhibitors are increasingly used after first-line therapies in EC, especially among patients initially receiving chemotherapy only. New immunological therapies such as PD(L)1 inhibitors hold great promise for patients with solid tumors. A clearer understanding of their real-world utilization is critical.

Programmable Pump for Intrathecal Morphine Delivery to Cisterna Magna: Clinical Implications in Novel Management of Refractory Pain Above Middle Thoracic Vertebrae Level Utilizing a Prospective Trial Protocol and Review

BACKGROUND

The cisterna Intrathecal Drug Delivery system (IDDS) with morphine has proven to be effective in treating refractory cancer pain above the middle thoracic vertebrae level in some countries. However, it has not been fully investigated in others. We designed the current project to investigate the efficacy and safety of cisterna IDDS for pain relief in refractory pain above the middle thoracic vertebrae level in advanced cancer patients.

METHODS

This study protocol allows for eligible cancer patients to receive the cisterna IDDS operation. Pain intensity (Visual Analogue scale, VAS), quality of life (36-Item Short-Form Health Survey, SF-36), and depression (Self-Rating Depression scale, SDS) are assessed along with side effects in the postoperative follow-up visits. Recent literature suggests a potential role for cisterna IDDS morphine delivery for refractory pain states above the middle thoracic level.

CONCLUSION

The results of this study may provide further evidence that cisterna IDDS of morphine can serve as an effective and safe pain relief strategy for refractory pain above the middle thoracic vertebrae level in advanced cancer patients.

A qualitative study exploring patient's experiences of oesophageal cancer surgery, through their personal advice to future patients

PURPOSE

Little is known about how patient's experience-based knowledge and advice after oesophageal cancer surgery may contribute to the understanding of how to improve HRQOL for future patients. In this study the advice that patients who were surgically treated for oesophageal cancer would like to share to future peers, based on their lived experiences were examined.

METHOD

A qualitative inductive content analysis was used to analyse one open-ended question from 63 transcribed interviews performed during 2019, within the nationwide Swedish prospective cohort study OSCAR (Oesophageal Surgery on Cancer patients - Adaption and Recovery study).

RESULTS

Patients had a broad range of advice to give from their experiences of oesophageal cancer surgery and recovery thereafter. Based on the analysis, three main categories were identified on the advice they wanted to pass on to future peers; health promoting advice, acknowledging the new situation, and advice on embracing support from others. The importance of being physically active, to maintain a positive mind set and to embrace support from both health care professionals as well as family and friends were central experiences that former patients wanted to share with their future peers.

CONCLUSION

This study sheds a light on the experiences that patients who have undergone oesophageal cancer surgery have, and what advice they would give to future patients going through the same procedure. The analysis reveals that patients have a variety of advice from their experiences that they want to pass on to future patients. Further studies are needed in order to examine how these advice are received by and can benefit future patients, as well as the pathways of how peer advice is best communicated.

What are the impact and the optimal design of a physical prehabilitation program in patients with esophagogastric cancer awaiting surgery? A systematic review

Background

Substantial postoperative complications occur after tumor resection for esophagogastric cancers. Physical prehabilitation programs aim to prepare patients for surgery by improving their functional status with the aim of reducing postoperative complications. This systematic review aims to summarize the effects of physical prehabilitation programs on exercise capacity, muscle strength, respiratory muscle function, postoperative outcomes, and health-related quality of life and to determine the optimal design of such a program to improve these outcomes in esophagogastric cancer patients undergoing tumor resection.

Methods

A systematic literature review was conducted using PubMed, The Cochrane Library, Scopus, and PEDro databases to identify studies evaluating the effects of physical prehabilitation program on exercise capacity, muscle strength, respiratory muscle function, postoperative complications, length of hospital stay, mortality, and health-related quality of life in patients with esophagogastric cancer awaiting surgery. Data from all studies meeting the inclusion criteria were extracted. The quality of each selected study was determined using the Downs and Black checklist.

Results

Seven studies with 645 participants were included. The preoperative exercise program consisted of respiratory training alone in three studies, a combination of aerobic and resistance training in two studies, and a combination of respiratory, aerobic, and resistance training in two studies. Training frequency ranged from three times a day to twice a week and each session lasted between 20 and 75 min. Four studies were of fair quality and three of good quality. Some studies reported improvements in maximal inspiratory pressure, inspiratory muscle endurance, postoperative (pulmonary) complications, and length of hospital stay in the preoperative exercise group compared to the control group.

Conclusion

This systematic review reports the current evidence for physical prehabilitation programs in patients with esophagogastric cancer awaiting surgery. However, due to the limited number of randomized controlled trials, the significant heterogeneity of exercise programs, and the questionable quality of the studies, higher quality randomized controlled trials are needed.

Postoperative Changes in Nutritional and Functional Status of Gastroesophageal Cancer Patients

OBJECTIVE

Disease-related malnutrition is a debilitating condition frequently observed in patients with cancer. The aim of the current study was to prospectively examine postoperative changes in nutritional and functional status of patients undergoing surgery for gastric, esophageal, and gastroesophageal junction cancer.

METHODS

Participants were prospectively recruited from September 2015 to September 2019. The assessment of malnutrition was based on the Patient-Generated Subjective Global Assessment tool. The functional assessment included the evaluation of muscle strength and physical performance, while muscle mass assessment was based on Skeletal Muscle Mass Index (SMI) derived from the analysis of computed tomography scans. The follow up of patients was scheduled at six months postoperatively.

RESULTS

A total of 98 patients were analyzed. Mean patient age was 60.79 ± 10.19 years and 80.6% were males. The mean unintentional weight loss at 6 months was 11.7 ± 8.0%. Patients who underwent McKeown esophagectomy reported the greatest weight loss postoperatively (16.2 ± 9.6%), whereas the lowest rate of weight loss was observed in patients who underwent partial gastrectomy (5.6 ± 6.7%). The rate of severe malnutrition declined at six months postoperatively (39.7% vs 27%). Muscle strength and physical performance were significantly deteriorated at 6 months postoperatively, except for the group of partial gastrectomy, while SMI significantly decreased in all groups of patients except for McKewon esophagectomy group. Finally, the prevalence of low muscle mass increased significantly from 43.5% in the preoperative period to 66.7% at the follow-up.

CONCLUSIONS

Our study revealed a significant deterioration in gastroesophageal cancer patient nutritional and functional status at six months postoperatively. The high prevalence of malnutrition and low muscle mass requires systematic follow-up and multidirectional monitoring in order to ensure the successful rehabilitation of these patients.

Subanesthetic ketamine in the ambulatory setting for refractory cancer pain: a 6-year retrospective at a cancer center

Pain is common in advanced cancer is often refractory to standard treatment. Ketamine has shown promise as an effective adjuvant despite conflicting reports. The aim of this retrospective was to analyze the efficacy of subanesthetic ketamine infusion in the ambulatory setting over an extended follow-up period of 3 months for symptoms related to refractory cancer pain. Forty seven patients treated with intravenous ketamine infusion for refractory cancer pain at a tertiary referral cancer center. Patients demonstrated improvement from baseline in worst, mean, current and least pain immediately after treatment (p < 0.05), worst pain 1 month after treatment (p = 0.003), and current pain (p = 0.036) and worst pain (p = 0.002) 3 months after treatment. Symptoms of quality of life were followed 1 month after treatment.

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.

Effect of direct oral feeding following minimally invasive esophagectomy on costs and quality of life

AIMS

Following (minimally invasive) esophagectomy, patients often rely on tube feeding, since oral intake is often delayed. Consequently, additional support by a dietician and home care is needed until oral intake is commenced. In this study, the effects of direct start of oral feeding compared with tube feeding following an esophagectomy was evaluated on treatment costs and health-related quality of life (QoL).

METHODS

Patients undergoing a minimally invasive esophagectomy were randomized in the NUTRIENT II study between controls (nil-per-mouth during 5 days and subsequent tube feeding) and a group in whom oral feeding was started directly postoperatively. Total hospital costs (including readmission and outpatient costs) and home care data for a period of 6 months after surgery were analyzed. QoL (measured using EORTC-QLQ-C30 and EORTC OG-25) was assessed preoperatively and 6 weeks, 12 weeks, and 6 months postoperatively.

RESULTS

A total 132 patients were included (n = 65 direct oral feeding group and n = 67 control group). Mean patient hospital costs were €26,014 in the intervention group over a 6-month period compared to €26,989 in the control group (p = .825). Furthermore, people with direct oral feeding required significantly less home care assistance; i.e. 23 (48.9%) intervention patients versus 37 (77.1%) control patients (p = .004). Also, QoL in patients with direct oral feeding progressed more quickly when compared to the control group.

LIMITATIONS

Hospital costs were derived from a single hospital unit whereas costs from all the participating units may be a better reflection of the cost deviation. Availability of homecare data was limited, leading to difficulty in detecting differences in costs.

CONCLUSION

This study suggests that direct oral feeding leads to similar total costs and a significantly reduced need for home care assistance. Furthermore, QoL in intervention group increased more quickly when compared to the control group.

Prediction of Lymph Node Metastasis in Superficial Esophageal Cancer Using a Pattern Recognition Neural Network

Background or Purpose

It is important to predict nodal metastases in patients with early esophageal cancer to stratify patients for endoscopic resection or esophagectomy. This study was to establish a novel artificial neural network (ANN) and assess its ability by comparing it with a traditional logistic regression (LR) model for predicting lymph node (LN) metastasis in patients with superficial esophageal squamous cell carcinoma (SESCC).

Methods

A primary cohort was established, composed of 733 patients who underwent esophagectomy for SESCC from December 2012 to December 2019. The following steps were applied: (i) predictor selection; (ii) development of an ANN and a LR model, respectively; (iii) cross-validation; and (iv) evaluation of performance between the two models. The diagnostic assessment was performed with sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, C-index, net reclassification improvement (NRI), and integrated discrimination improvement (IDI).

Results

The established ANN model had 6 significant predictors: a past habit of alcohol taking, tumor size, submucosal invasion, histologic grade, lymph-vessel invasion, and preoperative CT result. The ANN model performed better than the LR model in specificity (91.20% vs 72.59%, p=0.006), PPV (56.49% vs 39.78%, p=0.020), accuracy (90.72% vs 74.49%, p<0.0001), C-index (91.5% vs 86.8%, p<0.001), and IDI (improved by 23.3%, p<0.001). There were no differences between these two models in sensitivity (87.06% vs 83.21%, p=0.764), NPV (98.17% vs 95.21%, p=0.627), and NRI (improved by −1.1%, p=0.824).

Conclusion

This ANN model is superior to the LR model and may become a valuable tool for the prediction of LN metastasis in patients with SESCC.

Feasibility and Preliminary Effectiveness of a Tele-Prehabilitation Program in Esophagogastric Cancer Patients

Tele-rehabilitation provides better access to healthcare services and optimizes exercise adherence. However, its feasibility and effectiveness are unknown in the preoperative period in esophagogastric cancer patients. We aimed to assess the feasibility and the preliminary effects of a “tele-prehabilitation” program in esophagogastric cancer patients requiring surgery. Enrolled participants performed an internet-based tele-prehabilitation including aerobic, resistance and inspiratory muscle training over 2–4 weeks. The primary outcome was feasibility, measured in terms of recruitment, retention and attendance rates, adverse events and patient satisfaction. Secondary outcomes (functional exercise capacity, fatigue, quality of life, anxiety and depression) were assessed at baseline, presurgery, and 4 and 12 weeks postsurgery. Among the 24 eligible subjects, 23 were enrolled, 22 performed the intervention and 15 completed the study. Recruitment and retention rates were both 96%. Attendances to aerobic and resistance sessions and inspiratory muscle training were 77% and 68%, respectively. No adverse events occurred, and the satisfaction was excellent. After prehabilitation, participants significantly improved fatigue (p = 0.039), quality of life (p = 0.009), physical well-being (p = 0.034), emotional well-being (p = 0.005) and anxiety (p = 0.044). This study demonstrated the feasibility of a tele-prehabilitation in esophagogastric cancer patients undergoing surgery, with a high recruitment rate, retention rate and satisfaction, a good attendance to exercise sessions and no exercise-related adverse events.

Micronutrient Deficiencies Following Minimally Invasive Esophagectomy for Cancer

Over the past decades, survival rates for patients with resectable esophageal cancer have improved significantly. Consequently, the sequelae of having a gastric conduit, such as development of micronutrient deficiencies, become increasingly apparent. This study investigated postoperative micronutrient trends in the follow-up of patients following a minimally invasive esophagectomy (MIE) for cancer. Patients were included if they had at least one postoperative evaluation of iron, ferritin, vitamins B1, B6, B12, D, folate or methylmalonic acid. Data were available in 83 of 95 patients. Of these, 78.3% (65/83) had at least one and 37.3% (31/83) had more than one micronutrient deficiency at a median of 6.1 months (interquartile range (IQR) 5.4-7.5) of follow-up. Similar to the results found in previous studies, most common deficiencies identified were: iron, vitamin B12 and vitamin D. In addition, folate deficiency and anemia were detected in a substantial amount of patients in this cohort. At 24.8 months (IQR 19.4-33.1) of follow-up, micronutrient deficiencies were still common, however, most deficiencies normalized following supplementation on indication. In conclusion, patients undergoing a MIE are at risk of developing micronutrient deficiencies as early as 6 up to 24 months after surgery and should therefore be routinely checked and supplemented when needed.

Health-related quality of life in a randomized trial of neoadjuvant chemotherapy or chemoradiotherapy plus surgery in patients with oesophageal cancer (NeoRes trial)

BACKGROUND

There are few data comparing health-related quality of life (HRQoL) after neoadjuvant chemotherapy alone (nCT) compared with neoadjuvant chemoradiotherapy (nCRT) in patients with oesophageal cancer.

METHODS

In the NeoRes trial, patients were assigned randomly in a 1 : 1 ratio to receive either cisplatin 100 mg/m² on day 1 and an infusion of 750 mg per m² 5-fluorouracil over 24 h on days 1-5 in three 21-day cycles (nCT) or the same chemotherapy regimen, but with the addition of 40 Gy radiotherapy (nCRT). HRQoL data were collected at baseline, after neoadjuvant therapy and at 1, 3 and 5 years after surgery. The European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 and disease-specific modules were used.

RESULTS

Of 181 patients randomized, 165 were included in the analysis of HRQoL. In a direct comparison between the allocated treatments, odynophagia after completion of neoadjuvant therapy but before surgery (P = 0·047) and troublesome coughing at 3 years' follow-up (P = 0·011) were more pronounced in the nCRT arm. In the longitudinal analyses within each treatment arm, a large deterioration in HRQoL was noted at 1 year. Some recovery was seen in both arms over time but, after 3 and 5 years, patients in the nCRT arm reported more symptoms compared with baseline than patients in the nCT arm.

CONCLUSION

HRQoL after multimodal treatment for cancer of the oesophagus or gastro-oesophageal junction was impaired and more pronounced in patients who underwent nCRT, with only partial recovery over time.

The role of trait emotional intelligence in quality of life, anxiety and depression symptoms after surgery for esophageal or gastric cancer: A French national database FREGAT

OBJECTIVE

The main objective was to test the indirect effects of emotional competence (EC) after diagnosis (T1) on the health-related quality of life (HRQoL) after surgery (T2) of esogastric cancer patients via fewer anxiety and depression symptoms (T2).

METHODS

Data were collected from 30 French centers via the clinicobiological database French EsoGastric Tumors (FREGAT). Two hundred and twenty-eight participants completed a self-reported questionnaire at T1 and T2, assessing their EC (Profile of Emotional Competence (PEC)), HRQoL (EORTC Quality of Life Questionnaire-Core (QLQ-C30)), and anxiety and depression symptoms (Hospital Anxiety and Depression Scale (HADS)). Regression analyses were used to test the direct effects of intrapersonal and interpersonal EC on their anxiety/depression symptoms and HRQoL at T1 and T2. The PROCESS Macro in SPPS v.22 with bootstrap methods was used to test the indirect effects of intrapersonal and interpersonal EC at T1 on HRQoL at T2 via anxiety and depression symptoms.

RESULTS

EC predicted fewer anxiety and depression symptoms of patients at T1 and T2 and better HRQoL at T1. EC at T1 also predicted a better HRQoL at T2 via fewer anxiety and depression symptoms at T2.

CONCLUSIONS

Patients who tended to use their EC in daily life could be more effective in regulating the emotional impact of the cancer diagnosis and surgery. This explains why they reported fewer anxiety and depression symptoms, which in turn enabled a better perceived HRQoL after surgery. Therefore, reinforcing the use of patients' EC in daily life following their diagnosis could decrease their emotional distress and, in this way, improve their HRQoL in the preoperative and postoperative stages.

Effect of comorbid depression on health-related quality of life of patients with chronic diseases: A South Korean nationwide study (2007-2015)

OBJECTIVE

Patients with chronic physical diseases often have concomitant depression. Depression influences an individual's health and his or her overall health-related quality of life (HRQoL). The extent to which depression incrementally worsens HRQoL in patients with ≥1 comorbid physical chronic diseases remains unclear.

METHODS

This cross-sectional study is based on data of 50,844 respondents (age, ≥19 years) who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) (2007-2015). HRQoL was measured using the modified EuroQol five-dimensional (EQ-5D) score. Mean HRQoL scores were compared between subgroups of respondents with or without depression. The association between HRQoL and disease status was evaluated using multiple regression models after controlling for sociodemographic variables.

RESULTS

HRQoL score decreased when depression was concomitant. HRQoL score of respondents who had ≥3 chronic diseases with concomitant depression (mean = 0.83, SE = 0.010) were significantly lower (p = 0.002) than those of respondents who had ≥3 chronic diseases but no concomitant depression (mean = 0.87, SE = 0.007). Moreover, respondents with ≥3 chronic diseases comorbid with depression showed the largest negative association (coefficient = -0.133, p < 0.001) with HRQoL among all disease status groups.

CONCLUSION

Presence of depression incrementally worsened individual's HRQoL when comorbid with other physical diseases. Especially, depression showed substantial negative effect on HRQoL level in patients with ≥2 physical diseases.

Role of endoscopic therapy in early esophageal cancer

Esophageal carcinoma is a highly lethal cancer associated with high morbidity and mortality. Esophageal squamous cell carcinoma and esophageal adenocarcinoma are the two distinct histological types. There has been significant progress in endoscopic diagnosis and treatment of early stages of cancer using resection and ablation techniques, as shown in several trials in the recent past. Earlier detection of esophageal cancer and advances in treatment modalities have lead to improvement in the 5-year survival from 5% to about 20% in the past decade. Endoscopic eradication therapy is the preferred modality of treatment in cancer limited to mucosal layer of the esophagus as there is very low risk of lymph node metastasis, leading to high cure rates, low risk of recurrence and with few adverse effects. The most common adverse events seen are strictures, bleeding and rarely perforation which can be endoscopically managed. In patients with recurrent advanced disease or invasive tumor, esophagectomy with lymph node dissection remains the mainstay of treatment. There is debate on post-endoscopic surveillance with some studies suggesting closer follow up with upper endoscopy every 6 mo for the first 1-2 years and then annually for the 3 years while others recommending the appropriate action only if symptoms or other abnormalities develop. Overall, the field of endoscopic therapy is still evolving and focus should be placed on careful patient selection using a multidisciplinary approach.

Physical Activity Among Postoperative Esophageal Cancer Patients

BACKGROUND

Previous literature has reported that regular physical activity enhances health-related quality of life for cancer patients. However, there is a lack of studies that focus on physical activity among postoperative esophageal cancer patients.

OBJECTIVE

The aims of this study were to (1) describe the prevalence of physical activity among postoperative esophageal cancer patients, (2) explore variables related to physical activity (demographics, nutrition, dysphagia, and health-related qualify of life), and (3) examine potential reasons for inactivity among participants who scored low using case studies.

METHODS

In this cross-sectional design, physical activity was evaluated by the Japanese version of the International Physical Activity Questionnaire. Variables were analyzed using Spearman rank correlation coefficients, Mann-Whitney U tests, or Fisher exact tests.

RESULTS

Fifty-eight patients participated in this study; 79% met the recommended physical activity guidelines. Present occupational status and past leisure-time physical activity behavior before the cancer diagnosis were related to current leisure-time physical activity and meeting the guidelines postoperatively. Participants who scored 0 (little or no activity) in the questionnaire also scored low in health-related quality of life.

CONCLUSIONS

Participants performed especially well in physical activity related to leisure time and transportation. Positive reinforcement is needed for patients who perform adequate levels of physical activity, and reviewing the benefits of regular physical activity is encouraged for all.

IMPLICATIONS FOR PRACTICE

Occupational status and past leisure-time physical activity before diagnosis can be indicators for promoting physical activity among postoperative esophageal cancer patients. Inactive participants should be supported to promote both physical activity and health-related qualify of life.

Suicide rates among patients with cancers of the digestive system

OBJECTIVE

Previous studies have suggested that suicide rates are elevated among cancer patients relative to the general population. In this analysis, we comprehensively evaluated characteristics associated with higher suicide rates among patients with cancers of the digestive system.

METHODS

Using the United States Surveillance, Epidemiology, and End Results database, we identified all patients diagnosed with digestive system cancers during 2000 to 2014. Patients were classified as having died of suicide if their cause of death in Surveillance, Epidemiology, and End Results was listed as "suicide and self-inflicted injury." Suicide rates were compared to age-, sex-, and race-adjusted rates in the general population.

RESULTS

A total of 881 suicides were identified among 856 293 patients diagnosed with digestive system cancers. The suicide rate in this population was 32.8 per 100 000 person-years and was nearly twice that in the general population (standardized mortality ratio [SMR] = 1.91; 95% CI, 1.79-2.04). Suicide rates were significantly elevated for all cancer sites but were highest for esophageal (SMR = 5.03), pancreatic (SMR = 5.28), stomach (SMR = 2.84), and liver (SMR = 2.14) cancers. Standardized mortality ratios for suicide were highest within the first 5 years of diagnosis and increased with age at diagnosis for all sites except colon and stomach.

CONCLUSIONS

Patients with cancers of the digestive system have a higher incidence of suicide than the general population. Suicide rates among esophageal and pancreatic cancer patients are more than 5 times general population rates. The involvement of psychiatrists and other mental health professionals may be a critical component of cancer care for these high-risk patient subgroups.

The change of health-related quality of life after minimally invasive esophagectomy for esophageal cancer: a meta-analysis

BACKGROUND

Short- and long-term health-related quality of life (HRQL) was severely affected after surgery. This study aimed to assess the direction and duration of HRQL from 3- to 24-month follow-ups after minimally invasive esophagectomy (MIE) for esophageal cancer.

METHODS

A systematic literature search in MEDLINE, EMBASE, and the Cochrane database was performed for all potentially relevant studies published until February 2017. Studies were included if they addressed the question of HRQL with OERTC-QLQ-C30 and OES18. Primary outcomes were HRQL change at 3-month follow-up. Secondary outcomes were HRQL change from 3-, 6- (short-term) to 12- (mid-term), and/or 24-month (long-term) follow-ups.

RESULTS

Six articles were included to estimate the change in 24 HRQL outcomes after MIE. Most of the patients' HRQL outcomes deteriorated at short-term follow-up and some lasted to mid- or long-term after MIE. Patients' physical function and global QOL deteriorated from short- to long-term follow-ups, and emotional function had no change. The directions of dyspnea, pain, fatigue, insomnia, constipation, diarrhea, cough, and speech problems were increased. The deterioration in global function lasted 6 months, the increase in constipation and speech problems lasted 12 months, and insomnia increased more than 12 months after MIE.

CONCLUSIONS

The emotional function had no change after MIE. The global QOL become worse during early postoperative period; the symptoms of constipation, speech problems, and insomnia increased for a long time after MIE.

Prediction models for patients with esophageal or gastric cancer: A systematic review and meta-analysis

Background

Clinical prediction models are increasingly used to predict outcomes such as survival in cancer patients. The aim of this study was threefold. First, to perform a systematic review to identify available clinical prediction models for patients with esophageal and/or gastric cancer. Second, to evaluate sources of bias in the included studies. Third, to investigate the predictive performance of the prediction models using meta-analysis.

Methods

MEDLINE, EMBASE, PsycINFO, CINAHL, and The Cochrane Library were searched for publications from the year 2000 onwards. Studies describing models predicting survival, adverse events and/or health-related quality of life (HRQoL) for esophageal or gastric cancer patients were included. Potential sources of bias were assessed and a meta-analysis, pooled per prediction model, was performed on the discriminative abilities (c-indices).

Results

A total of 61 studies were included (45 development and 16 validation studies), describing 47 prediction models. Most models predicted survival after a curative resection. Nearly 75% of the studies exhibited bias in at least 3 areas and model calibration was rarely reported. The meta-analysis showed that the averaged c-index of the models is fair (0.75) and ranges from 0.65 to 0.85.

Conclusion

Most available prediction models only focus on survival after a curative resection, which is only relevant to a limited patient population. Few models predicted adverse events after resection, and none focused on patient’s HRQoL, despite its relevance. Generally, the quality of reporting is poor and external model validation is limited. We conclude that there is a need for prediction models that better meet patients’ information needs, and provide information on both the benefits and harms of the various treatment options in terms of survival, adverse events and HRQoL.

Long-term quality of life after esophagectomy with gastric pull-up

BACKGROUND AND OBJECTIVES

Data on long-term health-related quality of life (HRQL) after esophagectomy for cancer show contradictory results. The aim was to analyze long-term HRQL at 3 or more years after esophagectomy.

METHODS

Survivors were identified among patients who had undergone esophagectomy during 2007-2013 using the local clinic database. Quality of life was assessed using the European Organization for Research and Treatment of Cancer QLQ-C30 and OG25 questionnaires. Specific aspects were selected a priori and compared with published scores from European healthy subjects (mean difference, MD).

RESULTS

Sixty-five long-term survivors (median follow-up 4 years) were identified. All functional scales and most symptom scales were clinically similar between EC long-term survivors and European healthy subjects. Survivors reported more problems concerning eating (MD 13.1, 95% C.I. 10.6-15.6) and reflux (MD 19.7, 95% C.I. 15.9-23.5). HQRL variation from discharge to long term was available in 27 participants who reported improvements in role functioning (MD 40.1, 95%C.I. 24.3-56.0) and dysphagia (MD -41.9, 95% C.I. -51.7 to 32.0).

CONCLUSIONS

Long-term HRQL after esophagectomy is similar between EC survivors and European healthy subjects, despite persisting reflux and eating problems. Further research may focus on improvements of postoperative alimentary habits.

Oesophageal cancer

Oesophageal cancer is a clinically challenging disease that requires a multidisciplinary approach. Extensive treatment might be associated with a considerable decline in health-related quality of life and yet still a poor prognosis. In recent decades, prognosis has gradually improved in many countries. Endoscopic procedures have increasingly been used in the treatment of premalignant and early oesophageal tumours. Neoadjuvant therapy with chemotherapy or chemoradiotherapy has supplemented surgery as standard treatment of locally advanced oesophageal cancer. Surgery has become more standardised and centralised. Several therapeutic alternatives are available for palliative treatment. This Seminar aims to provide insights into the current clinical management, ongoing controversies, and future needs in oesophageal cancer.

Peer advice giving from posttreatment to newly diagnosed esophageal cancer patients

The benefits of peer support in cancer care include the sharing of information and experience, supporting adjustment by providing an illness trajectory which cancer patients can use to prepare for their own cancer journey. Information from peers is prioritized by esophageal cancer patients, yet the content of this experiential information is not well understood. The purpose of this study is to understand the content of peer advice giving from posttreatment to newly diagnosed esophageal cancer patients. Esophageal cancer survivors (n = 23) at median 67-months postdiagnosis completed a single open-ended survey item which asked for advice they would give to individuals newly diagnosed with esophageal cancer on how to cope emotionally with the cancer journey (including adjusting to life after treatment). Transcripts were assessed using qualitative content analysis, with five categories of advice identified: social support, psychological approach, realistic expectations, support from healthcare professionals and self-care. The categories of advice reported were distinct from information needs prioritized by clinicians. This study demonstrates that experiential information is accessible and has the potential to identify neglected information and supportive care needs, and may have a potential use in delivery of psychological support to newly diagnosed patients.

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

Although esophageal cancer is rare in the United States, 5-year survival and quality of life (QoL) are poor following esophageal cancer surgery. Although esophageal cancer has been surgically treated with esophagectomy through thoracotomy, an open procedure, minimally invasive surgical procedures have been recently introduced to decrease the risk of complications and improve QoL after surgery. The current study is a systematic review of the published literature to assess differences in QoL after traditional (open) or minimally invasive esophagectomy. We hypothesized that QoL is consistently better in patients treated with minimally invasive surgery than in those treated with a more traditional and invasive approach. Although global health, social function, and emotional function improved more commonly after minimally invasive surgery compared with open surgery, physical function and role function, as well as symptoms including choking, dysphagia, eating problems, and trouble swallowing saliva, declined for both surgery types. Cognitive function was equivocal across both groups. The potential small benefits in global and mental health status among those who experience minimally invasive surgery should be considered with caution given the possibility of publication and selection bias.

Randomized clinical trial of psychological support and sleep adjuvant measures for postoperative sleep disturbance in patients undergoing oesophagectomy

BACKGROUND

Major surgery such as oesophagectomy requires a postoperative stay in intensive care. Painful stimuli lead to sleep disturbance and impairment in quality of life. The aim of this study was to evaluate the effect of psychological counselling and sleep adjuvant measures on postoperative quality of sleep and quality of life.

METHODS

This RCT was performed between January 2013 and October 2015. Patients undergoing oesophagectomy for cancer were randomized into one of four groups receiving: psychological counselling plus sleep adjuvant measures during the ICU stay; psychological counselling alone; sleep adjuvant measures alone during the ICU stay; or standard care. The primary endpoint was impairment in quality of life measured using the European Organisation for Research and Treatment of Cancer C30-QL2 questionnaire between admission for surgery and discharge from hospital. The secondary endpoint was impairment in quality of sleep assessed by means of the Pittsburgh Sleep Quality Index between admission for surgery and hospital discharge.

RESULTS

The local ethics committee approved the early termination of the study because of relevant changes in the ICU setting. Some 87 patients were randomized and 74 patients were evaluated in the analysis. Psychological counselling reduced the impairment in quality of life (odds ratio 0·23, 95 per cent c.i. 0·09 to 0·61) and in quality of sleep (odds ratio 0·27, 0·10 to 0·73).

CONCLUSION

Perioperative psychological support reduces impairment in quality of life and quality of sleep after oesophagectomy. Registration number: NCT01738620 (http://www.clinicaltrials.gov).

Minimally invasive oesophagectomy versus open esophagectomy for resectable esophageal cancer: a meta-analysis

Background

Open esophagectomy (OE) is associated with significant morbidity and mortality. Minimally invasive oesophagectomy (MIO) reduces complications in resectable esophageal cancer. The aim of this study is to explore the superiority of MIO in reducing complications and in-hospital mortality than OE.

Methods

MEDLINE, Embase, Science Citation Index, Wanfang, and Wiley Online Library were thoroughly searched. Odds ratio (OR)/weighted mean difference (WMD) with a 95% confidence interval (CI) was used to assess the strength of association.

Results

Fifty-seven studies containing 15,790 cases of resectable esophageal cancer were included. MIO had less intraoperative blood loss, short hospital stay, and high operative time (P < 0.05) than OE. MIO also had reduced incidence of total complications; (OR = 0.700, 95% CI = 0.626 ~ 0.781, P_V < 0.05), pulmonary complications (OR = 0.527, 95% CI = 0431 ~ 0.645, P_V < 0.05), cardiovascular complications (OR = 0.770, 95% CI = 0.681 ~ 0.872, P_V < 0.05), and surgical technology related (STR) complications (OR = 0.639, 95% CI = 0.522 ~ 0.781, P_V < 0.05), as well as lower in-hospital mortality (OR = 0.668, 95% CI = 0.539 ~ 0.827, P_V < 0.05). However, the number of harvested lymph nodes, intensive care unit (ICU) stay, gastrointestinal complications, anastomotic leak (AL), and recurrent laryngeal nerve palsy (RLNP) had no significant difference.

Conclusions

MIO is superior to OE in terms of perioperative complications and in-hospital mortality.

Prospective Study of Malabsorption and Malnutrition After Esophageal and Gastric Cancer Surgery

OBJECTIVE

To study malabsorption and malnutrition after curative resection of esophageal and gastric cancer.

DESIGN

Prospective cohort study.

BACKGROUND

Improved cure rates for esophageal and gastric cancer have increased focus on health-related quality of life (HR-QL) in survivorship. Although malnutrition is well described in long-term follow-up, and gastrointestinal symptoms are common, data on gut and pancreatic-related malabsorption are scant.

METHODS

Disease-free patients at least 18 months after esophageal or gastric oncologic resections represented the study cohort. A modified Gastrointestinal Symptom Rating Scale questionnaire was completed, and weight, fecal elastase (FE), albumin, vitamins, and micronutrients measured preoperatively and at 1, 6, and 18 to 24 months postoperatively. Small intestinal bacterial overgrowth (SIBO) and changes in body composition were also evaluated postoperatively.

RESULTS

At a median follow-up of 23 months, 45 of 66 patients in a consecutive series were disease-free. Mean weight (78 ± 19 vs 67 ± 16 kg), body mass index (27 ± 5 vs 24 ± 5 kg/m), Vitamin A (1.7 ± 0.6 vs 1.2 ± 0.4 umol/L), and Vitamin E (28 ± 7 vs 20 ± 7 umol/L) were significantly decreased (P < 0.01) at last follow-up compared with preoperatively. Malabsorption was evident in 73% of patients, of whom 44% had FE < 200 μg/g and 38% had evidence of SIBO. Total body fat-free mass (175 ± 96 vs 84 ± 71, P < 0.001) and skeletal muscle index (44 ± 8 vs 39 ± 8, P = 0.007) were significantly decreased at 18 to 24 months.

CONCLUSIONS

Malabsorption and malnutrition are prevalent in survivorship of esophageal and stomach cancer. This may be underappreciated, and both gut and pancreatic insufficiency represent modifiable targets in the interdisciplinary approach to recovery of HR-QL.

Locally advanced esophageal cancer: What becomes of 5-year survivors?

OBJECTIVE

To determine the long-term outcomes of patients with locally advanced esophageal cancer (LAEC) who underwent esophagectomy and survived at least 5 years, and the predictors of disease-free survival (DFS) beyond 5 years.

METHODS

This was a retrospective review of a prospective database to identify patients with clinical stage T2N0M0 or higher LAEC. Medical records were reviewed to obtain demographic, clinical, and pathological characteristics, as well as data on recurrence and survival. Multivariable analysis of predictors of DFS beyond 5 years was performed using a Cox regression model.

RESULTS

Between 1988 and 2009, 355 of 500 patients underwent esophagectomy for cT2N0M0 or higher disease. Of these 355 patients, 126 were alive and disease-free at the 5-year follow-up, for an actuarial 5-year DFS of 33%. Recurrent esophageal cancer developed in 8 patients after 5 years. Among the 126 surviving patients, the actuarial overall survival was 94% at 7 years and 80% at 10 years. On multivariable analysis, the sole significant predictor of DFS after the 5-year time point was non-en bloc resection at the original operation (P = .006). Pulmonary-related deaths accounted for 10 out of 22 noncancer deaths. A second primary cancer developed in 23 of the 126 surviving patients.

CONCLUSIONS

Prolonged survival can be obtained in one-third of patients with LAEC. An en bloc resection at the original operation is the most significant predictor of prolonged survival. Survivors experience a high rate of second primary cancer and an apparently high rate of deaths from pulmonary disease. Careful follow-up is necessary for these patients, even after the 5-year mark.

Health related quality of life after oesophagectomy: elderly patients refer similar eating and swallowing difficulties than younger patients

Background

Oesophagectomy for cancer could be safe and worthwhile in selected older patients, but less is known about the effect of oesophagectomy on perceived quality of life of such delicate class of cancer patients. The aim of this study was to evaluate the impact of oesophagectomy for cancer in elderly patients in term of health-related quality of life.

Methods

We retrospectively evaluated all consecutive patients who underwent oesophagectomy for cancer at the Surgical Oncology Unit of the Veneto Institute of Oncology between November 2009 and March 2014. Quality of life was evaluated using EORTC C-30 and OES-18 questionnaires at admission, at discharge and 3 months after surgery. Adjusted multivariable linear mixed effect models were estimated to assess mean score differences (MDs) of selected aspects in older (≥70 years) and younger (<70 years) patients.

Results

Among 109 participating patients, 23 (21.1 %) were at least 70 years old and 86 (78.9 %) were younger than 70 years. Global quality of life was clinically similar between older and younger patients over time (MD 4.4). Older patients reported clinically and statistically significantly worse swallowing saliva (MD 17.4, 95 % C.I. 3.6 to 31.2), choking when swallowing (MD 13.8, 95 % C.I. 5.8 to 21.8) and eating difficulties (MD 20.1 95 % C.I. 7.4 to 32.8) than younger patients only at admission.

Conclusions

Early health-related quality of life perception after surgery resulted comparable in older and younger patients. This result may also be due to some predisposition of the elderly to adapt to the new status.

Minimally invasive esophagectomy for dysplastic Barrett's esophagus

A substantial portion of patients diagnosed preoperatively with high grade dysplasia (HGD) alone will have occult esophageal adenocarcinoma on analysis of the surgical specimen. Therefore, because of an increased risk of disease progression and malignancy, patients with HGD should be referred for esophagectomy promptly when endoscopic therapy has failed. The required extent of lymphadenectomy in this cohort of patients is unknown because of the variable incidence of submucosal cancer observed. Improvements in perioperative care, adoption of a minimally invasive surgical approach, and centralization of esophageal cancer services have substantially reduced the rates of mortality and morbidity associated with esophagectomy in recent years. Minimally invasive esophagectomy should be considered the treatment of choice in patients with dysplastic Barrett's esophagus that is refractory to endoscopic therapy or those at high risk of invasive cancer.

Developing core outcomes sets: methods for identifying and including patient-reported outcomes (PROs)

BACKGROUND

Synthesis of patient-reported outcome (PRO) data is hindered by the range of available PRO measures (PROMs) composed of multiple scales and single items with differing terminology and content. The use of core outcome sets, an agreed minimum set of outcomes to be measured and reported in all trials of a specific condition, may improve this issue but methods to select core PRO domains from the many available PROMs are lacking. This study examines existing PROMs and describes methods to identify health domains to inform the development of a core outcome set, illustrated with an example.

METHODS

Systematic literature searches identified validated PROMs from studies evaluating radical treatment for oesophageal cancer. PROM scale/single item names were recorded verbatim and the frequency of similar names/scales documented. PROM contents (scale components/single items) were examined for conceptual meaning by an expert clinician and methodologist and categorised into health domains. A patient advocate independently checked this categorisation.

RESULTS

Searches identified 21 generic and disease-specific PROMs containing 116 scales and 32 single items with 94 different verbatim names. Identical names for scales were repeatedly used (for example, 'physical function' in six different measures) and others were similar (overlapping face validity) although component items were not always comparable. Based on methodological, clinical and patient expertise, 606 individual items were categorised into 32 health domains.

CONCLUSION

This study outlines a methodology for identifying candidate PRO domains from existing PROMs to inform a core outcome set to use in clinical trials.
