[PMID: 36085137 DOI: 10.1016/j.brachy.2022.07.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 07/23/2022] [Accepted: 07/25/2022] [Indexed: 12/14/2022]
Abstract
PURPOSE Brachytherapy is most often applied in the curative or salvage setting, but many forms of brachytherapy can be helpful for symptom palliation. Declining utilization is seen, for multiple reasons, such as lack of awareness, insufficient expertise, or poor access to equipment. High level evidence for many types of palliative brachytherapy has been lacking. The objective of the current study was to review the evidence for utilization and efficacy of brachytherapy to palliate symptoms from cancer. MATERIALS AND METHODS We performed a systematic search in EMBASE and MEDLINE for English-language articles published from January 1980 to May 2022 that described brachytherapy used for a palliative indication in adults with a diagnosis of cancer (any subtype) and at least one symptom related outcome. Individual case reports and conference abstracts were excluded. All publications were independently screened by two investigators for eligibility. RESULTS The initial search identified 3637 abstracts of which 129 were selected for in-depth review. The number of studies (total number of patients) included in the final analysis varied widely by tumor site with the majority (68.2%) involving either lung or esophageal cancer. Despite a limited number of prospective trials that assessed the efficacy of brachytherapy for symptom management, there was a positive effect on palliation of symptoms across all tumor types. There was no clear trend in the number of publications over time. The most commonly cited symptom indications for palliation by brachytherapy were dysphagia, dyspnea, pain and bleeding. CONCLUSIONS Brachytherapy can provide palliation for patients with advanced cancer, across different tumor sites and clinical scenarios. However, high level evidence in the literature to support palliative applications of brachytherapy is lacking or limited for many tumor sites. There appears to be a strong publication bias towards positive studies in favor of brachytherapy. Beyond anecdotal reports and individual practices, outcomes research can further our understanding of the role of brachytherapy in palliating advanced cancers of all types, and should be encouraged.

Abstract
Oesophageal cancer (OC) is an aggressive neoplasm that manifests in the gastrointestinal tract and is the result of numerous factors that can contribute to the development of the disease. These may include old age, nutritional deficiencies, oesophageal obstruction and food ingestion difficulties. Environmental factors serve a large role in increasing the risk of developing OC. Two factors that serve an increasing risk of developing OC are the use of tobacco and the consumption of alcohol. Genetic factors also exhibit a large effect on the risk of developing OC, for example, the causative genes in Black Africans differ from other races. OC is 3–4 times more common among men than women. OC has been previously reported in >450 000 individuals worldwide, and its incidence is increasing. The current review compares OC in low to middle-income countries with developed countries. The incidence of OC, particularly squamous cell carcinoma (SCC) is high in low and middle-income countries. In developed countries, the incidence of SCC is low compared with adenocarcinoma. The majority of OC cases are diagnosed in the late stages of the disease, leading to high mortality rates. The current review aimed to discuss factors that contribute to the development of this disease in different geographical areas and genetic mechanisms governing these findings. The current review also aims to discuss the preventative treatment options for the disease, and also discusses the diagnosis and surveillance in five LMICs, including South Africa, China, Tanzania, India and Brazil.

Effectiveness of several external beam radiotherapy schedules for palliation of esophageal cancer. Clin Transl Radiat Oncol 2019; 17:24-31. [PMID: 31193091 PMCID: PMC6517531 DOI: 10.1016/j.ctro.2019.04.017] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2018] [Revised: 04/21/2019] [Accepted: 04/22/2019] [Indexed: 01/11/2023] Open
Abstract
External beam radiotherapy provides good symptom control for esophageal cancer. A higher dose schedule is related to a longer time to second intervention. Life expectancy is valuable in selecting the optimal palliative treatment schedule.
Background and purpose Although external beam radiotherapy (EBRT) is frequently used for palliative treatment of patients with incurable esophageal cancer, the optimal schedule for symptom control is unknown. This retrospective study evaluated three EBRT schedules for symptom control and investigated possible prognostic factors associated with second intervention and overall survival (OS). Material and methods Patients with esophageal cancer treated with EBRT with palliative intent between January 2009 and December 2015 were evaluated. Univariate and multivariate Cox regression models estimated the effect of treatment schedule (20 Gy in 5 fractions, 30 Gy in 10 fractions or 39 Gy in 13 fractions) on OS. To study the effect of prognostic factors on time to second intervention (repeat EBRT, intraluminal brachytherapy or stent placement) a competing risk model with death as competing event was used. Results 205 patients received 20 Gy (31%), 30 Gy (38%) or 39 Gy (32%). Improvement of symptoms was observed in 72% with no differences between schedules. Median OS after 20 Gy, 30 Gy and 39 Gy was 4.6 months (95%CI 2.6–6.6), 5.2 months (95%CI 3.7–6.7) and 9.7 months (95%CI 6.9–12.5), respectively. Poor performance status (HR 2.25 (95%CI 1.53–3.29)), recurrent esophageal cancer (HR 1.69 (95%CI 1.15–2.47)) and distant metastasis (HR 1.73 (95%CI 1.27–2.35)) were significantly related to worse OS. Treatment with 30 Gy and 39 Gy was related to longer time to second intervention compared to 20 Gy (adjusted cause specific HR 0.50 (95%CI 0.25–0.99) and 0.27 (95%CI 0.13–0.56), respectively). Conclusions Palliative EBRT provides good symptom control in patients with symptomatic esophageal cancer. A higher dose schedule was related to a longer time to second intervention. Hence, selection based on life expectancy is vital to prevent unnecessary long treatment schedules in patients with expected short survival, and limit the chance of second intervention when life expectancy is longer.

Abstract
Esophageal squamous cell carcinoma (ESCC) is a frequent and lethal neoplasia. As recent advances in targeted therapy have not improved ESCC prognosis, characterization of molecular alterations associated to this tumor is of foremost relevance. In this study, we analyze, for the first time, the complete genomic profile of ESCC by RNA-seq. TP53 was the most frequently mutated gene in the investigation and validation sets (78.6% and 67.4%, respectively). Differential expression analysis between tumor and nontumor adjacent mucosa showed 6698 differentially expressed genes, most of which were overexpressed (74%). Enrichment analysis identified overrepresentation of Wnt pathway, with overexpressed activators and underexpressed inactivators, suggesting activation of canonical and noncanonical Wnt signaling pathways. Higher WNT7B expression was associated with poor prognosis. Twenty-one gene fusions were identified in 50% of tumors, none of which involving the same genes in different patients; 71% of fusions involved syntenic genes. Comparisons with TCGA data showed co-amplification of seven gene pairs involved in fusions in the present study (~33%), suggesting that these rearrangements might have been driven by chromoanagenesis. In conclusion, genomic alterations in ESCC are highly heterogeneous, impacting negatively in target therapy development.

Abstract
Esophageal squamous cell carcinoma (ESCC) presents poor prognosis, and patients diagnosed with this tumor currently lack target treatments. Therefore, in order to identify potential targets for ESCC treatment, we carried out a transcriptome analysis with ESCC and paired nonmalignant surrounding mucosa samples, followed by a master regulator analysis, and further explored the role of the identified central regulatory genes through in vivo and in vitro assays. Among the transcription factors deregulated/enriched in ESCC, we focused on FOXM1 because of its involvement in the regulation of critical biological processes. A new transcriptome analysis performed with ESCC cell lineage TE-1 showed that the modulation of FOXM1 expression resulted in PIK3R3 expression changes, whereas chromatin immunoprecipitation assay revealed that FOXM1 was capable of binding onto PIK3R3 promoter, thus demonstrating that PIK3R3 is a new FOXM1 target. Furthermore, FOXM1 overexpression resulted in the activation of PIK3/AKT signaling pathway through PIK3R3-mediated AKT phosphorylation. Finally, the analysis of the clinic-pathological data of ESCC patients revealed that overexpression of both FOXM1 and PIK3R3 was associated with poor prognosis, but only the latter was an independent prognosis factor for ESCC patients. In conclusion, our results show that FOXM1 seems to play a central role in ESCC carcinogenesis by upregulating many oncogenes found overexpressed in this tumor. Furthermore, PIK3R3 is a novel FOXM1 target that triggers the activation of the PI3K/AKT pathway in ESCC cells.

Abstract
BACKGROUND We assessed the use of external beam radiotherapy, brachytherapy chemoradiotherapy and chemotherapy in patients with metastatic esophageal cancer and evaluated the effect on overall survival. METHODS We included all patients diagnosed with synchronous metastatic esophageal cancer in the south of the Netherlands between 1 January 1994 and 31 December 2013. Proportions of patients treated with external beam radiotherapy, brachytherapy, chemoradiotherapy and chemotherapy were described with respect to the period of diagnosis, patient and tumor characteristics. Independent risk factors for death were discriminated. RESULTS A total of 1020 patients were included, 61.5% of these patients received palliative treatment with external beam radiotherapy, chemoradiotherapy, brachytherapy and/or chemotherapy. The use of external beam radiotherapy decreased from 44.5% in 1994 to 22.2% in 2013 (p = 0.0001), whereas the use of chemoradiotherapy increased from 2.9% in 1994 to 19.1% in 2013 (p < 0.0001). The prescription of systemic chemotherapy as single modality increased from 13.9% to 30.5% (p < 0.0001). The use of brachytherapy decreased from 20.9% in 1994 to 7.4% in 2013 (p = 0.0013). The odds of receiving external beam radiotherapy, brachytherapy, chemoradiotherapy and chemotherapy were influenced by different tumor and patient characteristics, such as age, gender, histologic subtype and number of metastatic sites. The median overall survival in patients with metastatic esophageal cancer significantly improved over time from 18 weeks (one-year survival rate 14.4%) in 1994-1998 to 25 weeks (one-year survival rate 22.4%) in 2009-2013. Patients treated with chemoradiotherapy had the most favorable prognosis, followed by patients treated with chemotherapy as a single modality. CONCLUSION The median overall survival of patients diagnosed with metastatic esophageal cancer improved from 18 weeks in 1994-1998 to 25 weeks in 2009-2013. Although this increase could be attributed to stage migration, our population-based study suggests that major changes in treatment strategies and appropriate patient selection might have played a role as well.

Abstract
Les patients atteints du cancer de l’œsophage ont souvent une maladie localement avancée, la dysphagie est le symptôme majeur chez la plupart de ces patients, plusieurs modalités thérapeutiques ont été utilisées pour améliorer cette dysphagie. Le but de ce travail est d’étudier l'efficacité et la tolérance de la curiethérapie haut débit de dose (HDR) endo-luminale dans le traitement palliatif des cancers de l’œsophage inopérable. Sur une période de 15 ans, l’étude a inclus les patients atteints de cancer de l’œsophage inopérable et/ou métastatique avec une dysphagie, sans extension à l'hypopharynx ou a la trachée et qui ont bénéficié d'une curiethérapie HDR avec ou sans radiothérapie externe à visée palliative. Au total 46 patients ont été inclus dans l’étude, 58,7% étaient des hommes, 42,2% avaient une dysphagie grade 2 et 37,8% étaient aphagiques, 78,6% des patients étaient performance satus PS 2, l'amaigrissement à été trouvé chez 81,4%, la localisation de la tumeur était surtout au niveau du tiers moyen et inférieur dans 97,8%, la hauteur médiane de la tumeur était de 7 cm (5,5-9), le carcinome épidermoïde était le type histologique le plus fréquent chez 31 patients (70,5%). Après un médiane de suivi de 5 mois, l'amélioration de la dysphagie a été retrouvée chez 76% des malades (p1]. L′incidence la plus élevée est observée dans certains pays notamment en Asie et en Afrique, et l′incidence dans les pays développés occidentaux est en augmentation [2]. Selon le registre du cancer de Rabat 2006-2008, le cancer de l’œsophage est rare et constitue 1,5% de tous les cancers chez l'homme [3]. Le taux de survie globale à 5 ans est de 8%, avec 80% des décès liés à l’évolution locale de la maladie [4]. Pour la minorité des patients avec une maladie localisée, le traitement par radiochimiothérapie concomitante avec ou sans chirurgie permet une amélioration de la survie [5]. Plus de 50% des patients atteints de cancer de l′œsophage ont une maladie inopérable au moment du diagnostic due à une tumeur localement avancée, des métastases ou un mauvais état général avec une médiane de survie globale de 2,5 à 9,9 mois [6]. La majorité de ces patients ont besoin de soins palliatifs pour soulager la dysphagie qui est présente chez plus de 70% des patients et qui est responsable d'une dégradation importante de la qualité de vie [7]. À l′heure actuelle, plusieurs modalités de prise en charge sont disponibles pour le traitement palliatif de cette dysphagie. Les options de traitement les plus couramment utilisées comprennent le placement de stent métallique [8–10], le traitement au laser [11], et la curiethérapie avec ou sans radiothérapie externe et ou éventuellement une chimiothérapie [12–15]. Une méta-analyse a conclu qu'il n'y a pas de supériorité claire de l'une des méthodes utilisées dans la palliation du cancer de l’œsophage, le choix de l'une de ces méthodes dépend de l'expérience du centre et de l’état du patient. Cette méta-analyse a aussi démontré que la pose d'une prothèse métallique expansible et la curiethérapie étaient les deux méthodes de référence, la première étant la plus rapide pour améliorer la dysphagie, mais la seconde constitue une réelle alternative pouvant améliorer la survie et la qualité de vie [16]. Un inconvénient du traitement au laser est la nécessité de répéter les séances afin d'obtenir et de maintenir le bénéfice [17, 18]. Dans notre centre la curiethérapie est souvent utilisée pour pallier à la dysphagie. Le but de notre travail est de déterminer l'efficacité et la tolérance de la curiethérapie dans le traitement palliatif du cancer de l’œsophage.

Measuring relief of dysphagia in locally advanced esophageal carcinoma patients submitted to high-dose-rate brachytherapy. Brachytherapy 2014; 14:84-90. [PMID: 25447340 DOI: 10.1016/j.brachy.2014.09.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2014] [Revised: 09/15/2014] [Accepted: 09/17/2014] [Indexed: 11/21/2022]
Abstract
BACKGROUND AND PURPOSE Esophageal neoplasm has a poor prognosis, and palliative care remains an important goal of treatment. The purpose of this study was to assess the ability of high-dose-rate brachytherapy (HDRB) to improve dysphagia in 115 patients treated at our institution. METHODS AND MATERIALS Patients previously submitted to external beam radiotherapy that at least, 1 month after, presented with residual disease and persistent dysphagia, were given HDRB as palliative treatment. Patients with tumors extending to the level of cardia and those with cervical esophageal lesions were also eligible. HDRB consisted of three fractions of 500 cGy given weekly. Dysphagia was assessed using a food texture-based scale classified according to the type of food patients were able to swallow (absent, solid, pasty, or liquid). At the end of treatment, a single-category shift in dysphagia classification was scored as +1 (e.g., liquid to pasty) or -1 (e.g., solid to pasty), and a dual-category shift was scored as +2 (e.g., liquid to solid) or -2 (e.g., absent to pasty). RESULTS Most patients (51.1%) had improvement of dysphagia, and 55.3% of this group experienced one-point improvement. Procedural complications included stricture (38.2%), bleeding (7%), and fistula (8.7%). In the present study, 13 patients with cervical esophageal lesions underwent HDRB without fistula formation. CONCLUSIONS Esophageal HDRB effectively reduces dysphagia. Tumor location was not related to development of complications.

Abstract
CONTEXT The difficulties in defining a palliative care patient accentuate the need to provide stringent descriptions of the patient population in palliative care research. OBJECTIVES To conduct a systematic literature review with the aim of identifying which key variables have been used to describe adult palliative care cancer populations in randomized controlled trials (RCTs). METHODS The data sources used were MEDLINE (1950 to January 25, 2010) and Embase (1980 to January 25, 2010), limited to RCTs in adult cancer patients with incurable disease. Forty-three variables were systematically extracted from the eligible articles. RESULTS The review includes 336 articles reporting RCTs in palliative care cancer patients. Age (98%), gender (90%), cancer diagnosis (89%), performance status (45%), and survival (45%) were the most frequently reported variables. A large number of other variables were much less frequently reported. CONCLUSION A substantial variation exists in how palliative care cancer populations are described in RCTs. Few variables are consistently registered and reported. There is a clear need to standardize the reporting. The results from this work will serve as the basis for an international Delphi process with the aim of reaching consensus on a minimum set of descriptors to characterize a palliative care cancer population.

Abstract
BACKGROUND Esophageal self-expandable stents (SESs) effectively treat strictures and leaks but may be complicated by a stent-associated esophagorespiratory fistula (SERF). Little is known about SERFs. OBJECTIVE To determine the incidence, morbidity, mortality, and risk factors for SERF. DESIGN Retrospective case-control study. SETTING Single referral center. PATIENTS All adults undergoing esophageal SES placement during a 10-year period. INTERVENTION Stent placement. MAIN OUTCOME MEASUREMENTS Occurrence of SERF, morbidity, and mortality. RESULTS A total of 16 of 397 (4.0%) patients developed SERF at a median of 5 months after stent placement (range 0.4-53 months) including 6 of 94 (6%), 10 of 71 (14%), and 0 of 232 (0%) of those with lesions in the proximal, middle, and distal esophagus, respectively (overall P < .001). SERF occurred in 10% of those with proximal and mid-esophageal lesions, including 14% with benign strictures, 9% with malignant strictures, and none with other indications for SES placement (P = .27). The risk was highest (18%) in patients with benign anastomotic strictures. Risk factors for development of SERF included a higher Charlson comorbidity index score (odds ratio [OR] 1.47 for every 1-point increase; P = .04) and history of radiation therapy (OR 9.41; P = .03). Morbidity associated with SERF included need for lifelong feeding tubes in 11 of 22 (50%) and/or tracheostomy or mechanical ventilation in 5 of 22 (23%). Median survival after diagnosis was 4.5 months (range 0.35-67), and 7 patients survived less than 30 days. LIMITATIONS Retrospective design, limited statistical power. CONCLUSION SERF is a morbid complication of SES placement for strictures of the proximal and mid-esophagus. The dominant risk factors for development of SERF are prior radiation therapy and comorbidity score.

Abstract
BACKGROUND Esophageal stenting is increasingly being utilized to treat a variety of benign and malignant esophageal conditions. The aim of our study was to review our experience with self-expanding metal, plastic, and hybrid stents in the treatment of esophageal disease on a thoracic surgical service. METHODS The study population consisted of 126 patients undergoing placement of 133 stents at a single institution from 2000 to 2008. Data were reviewed retrospectively for patient characteristics, indications, complications, reinterventions, and efficacy. RESULTS Most stents were placed for palliation of dysphagia due to advanced esophageal cancer (90 of 133; 68%) or extrinsic compression from lung cancer (13 of 133; 9.8%). A total of 123 self-expanding metal stents (SEMS), 7 self-expanding plastic stents (SEPS), and 3 hybrid stents were placed. Of the SEMS, 57 were uncovered and 66 were covered. Malignant obstruction was typically palliated with SEMS, while covered stents were chosen for perforations or anastomotic leaks. The median length of stay was 1 day. Complications occurred in 38.3% of stent placements, with a single perioperative mortality resulting from massive hemorrhage on postoperative day 4. Most complications resulted from stent impaction (12.8%), migration (9.7%), or tumor ingrowth (5.3%). Tumor ingrowth was uncommon with uncovered stents (2 of 57; 3.5%). Stent migration was common with SEPS (4 of 7; 57%), or hybrid stents (2 of 3; 67%). Survival was short in patients with underlying malignancy (median 104 days for esophageal cancer and 48 days for lung cancer), with 20% of patients surviving less than 1 month. CONCLUSIONS Esophageal stent placement is safe and reliable. The goals of therapy are typically met with a single intervention. The majority of patients require no further interventions, though life expectancy often is short and patient selection may be difficult. Most complications are due to stent obstruction, though stent migration is an issue particularly with SEPS and hybrid stents. Esophageal surgeons should be adept at stent placement.

Abstract
In a retrospective review, in order to describe the palliative care and prognosis of patients with advanced cancer of the esophagus, the clinical characteristics and the treatment modalities applied were explored in relation to survival and symptom relief for 261 patients treated without curative potential. The data were obtained from a study of all patients with cancer of the esophagus treated at the Norwegian Radium Hospital in the 10-year period from 1990 to 1999. Medical data of the patients were reviewed and missing clinical information was retrieved from local hospitals and general practitioners. The patients were divided into three groups based upon the overall survival from start of treatment to death. Survival ≤3 months is in this paper, defined as 'short,' while survival > 6 months is defined as 'long.' Median survival for the total group of patients was 4 months. The 1-, 2-, and 3-year survival was 8%, 3%, and 1%, respectively. Patients with short survival (n= 107) had more advanced disease, lower performance status, and more dysphagia, weight loss, and pain and used more analgesics than patients with long survival (n= 91). Tumor characteristics such as localization, tumor length, and histology were not significantly associated with survival. This result was confirmed in a logistic regression analysis (with backward stepwise elimination) including sex, age, clinical stage, tumor length, tumor localization, histology, performance status, dysphagia, weight loss, and pain, where clinical stage, performance status, weight loss, and pain were included in the final model. A large variety of first-line palliative treatments were applied within the studied time period; external radiotherapy ± brachytherapy (n= 149), brachytherapy alone (n= 44), endoluminal stent (n= 28), laser evaporization (n= 8), chemotherapy (n= 5), and best supportive care only (n= 27). There were no clear differences in the effect on dysphagia between the modalities. Fourteen percent of the patients had treatment related complications. In conclusion, symptoms, performance status, and use of analgesics seemed to better prognosticate survival than tumor characteristics other than stage of disease. Our study reveals that knowledge about prognostic factors is crucial for the choice of palliative treatment. Even though all of the different treatment modalities seemed to provide relief of dysphagia, several other factors should be considered when deciding which treatment modality to offer. The time to onset of relief, duration of response, level of complications, and time spent in hospital should be a part of the decision-making process when selecting the appropriate treatment.

Abstract
PURPOSE The aim of this work was to analyze the efficacy of high-dose-rate brachytherapy in the management of patients with esophageal cancer. METHODS AND MATERIALS Between 2001 and 2008, 104 patients (88 males and 16 females) received a brachytherapy treatment as a part of a personalized multimodal approach. The median age was 72 years, and the median Karnofsky performance status was 60. Brachytherapy was used in different situations: to complete a primary treatment with radical intent in patients not suitable for surgery; to control local recurrences; or to obtain a rapid and durable palliation of dysphagia in patients with metastases or in poor general condition. In selected cases, endoscopic ultrasound images were integrated in treatment planning procedure to obtain a more accurate volume definition. Efficacy in controlling dysphagia was assessed 1 month after brachytherapy. RESULTS Fifty-one patients received a radical treatment, and 53 patients were treated to relieve the symptoms. The median overall survival was 20.8 months. Lymph node involvement was found to be a significant prognostic factor for overall survival and dysphagia. Dysphagia was controlled in 88 patients (84.6%), and the median dysphagia-free interval was 17.5 months. Early and late adverse events were generally mild to moderate. The most severe effects were esophagotracheal fistulas, observed in 3 patients. CONCLUSIONS Brachytherapy has an important role in the management of esophageal cancer with a low rate of complications. endoscopic ultrasound-assisted treatment planning can be useful for a better individualization of curative treatments.

Abstract
Esophageal strictures are a problem commonly encountered in gastroenterological practice and can be caused by malignant or benign lesions. Dysphagia is the symptom experienced by all patients, regardless of whether their strictures are caused by malignant or benign lesions. The methods most frequently used for palliation of malignant esophageal strictures are stent placement (particularly in patients with an expected survival of 3 months or less) and brachytherapy (in patients with a life expectancy of more than 3 months). Brachytherapy has been shown to be beneficial in patients with an expected survival of longer than 3 months with regard to (prolonged) dysphagia improvement, complications and quality of life. The mainstay of benign esophageal stricture treatment is dilation. Although dilation usually results in symptomatic relief, recurrent strictures do occur. In order to predict which types of strictures are most likely to recur, it is important to differentiate between esophageal strictures that are simple (i.e. focal, straight strictures with a diameter that allows endoscope passage) and those that are more complex (i.e. long (>2 cm), tortuous strictures with a narrow diameter). These complex strictures are considered refractory when they cannot be dilated to an adequate diameter. Novel treatment modalities for refractory strictures include temporary stent placement and incisional therapy.

Abstract
Placement of self-expanding metal stents (SEMS) for palliation of malignant stenoses at the gastroesophageal junction is often associated with stent migration and reflux symptoms. SEMS with an antireflux mechanism have been developed to overcome the latter problem. The aim of this study was to evaluate the safety and efficacy of antireflux Z-stents. Patients with advanced squamous cell or adenocarcinoma of the distal esophagus or cardia suffering from dysphagia received an antireflux Z-stent. Technical success, complications of the procedure, clinical symptoms before and after stent placement, reinterventions and survival were recorded. Follow-up was accomplished by patient interviews and a standardized questionnaire for primary care physicians. Eighteen consecutive patients received an antireflux Z-stent. Seventeen of 18 stents were placed technically successful in a single endoscopic procedure. Mean dysphagia score improved from 2.2 to 0.6. Four patients (22%) had permanent reflux symptoms, an additional nine (50%) were taking proton pump inhibitors on a regular basis. In 10 patients, a re-intervention was necessary mainly due to dislocation of the stent. To ensure adequate nutrition three and two patients received a percutaneous gastrostomy and a jejunostomy, respectively. Median survival from stent insertion was 54 days (range, 3-201). Although placement of an antireflux Z-stent is technically feasible, its application is hampered by frequent stent migration and insufficient prevention of gastroesophageal reflux. Further technical improvements of stents or alternative methods like brachytherapy are required for satisfactory palliation of malignant gastroesophageal stenosis.

Abstract
Over the past 5 years, new developments in the palliative treatment of incurable cancer of the oesophagus and gastro-oesophageal junction have been introduced with the aim of palliating dysphagia and improving the survival of patients. Stent placement is currently the most widely used treatment for palliation of dysphagia from oesophageal cancer. A stent offers rapid relief of dysphagia; however, current recurrent dysphagia rates vary between 30 and 40%. Recently introduced new stent designs are likely to reduce recurrent dysphagia by decreasing stent migration and non-tumoral tissue overgrowth. Intraluminal radiotherapy (brachytherapy) has been demonstrated to compare favourably with stent placement in long-term effectiveness and safety. A disadvantage of brachytherapy, however, is that one-fifth of patients need an additional treatment because of persistent tumour growth in the oesophagus. A solution may be to administer brachytherapy not in a single fraction but in multiple fractions. Finally, efforts have been undertaken to improve survival of patients by using chemotherapy. In the future, a multimodal approach--for example by combining stent placement with chemotherapy or radiotherapy--may improve the prognosis of patients without jeopardizing their quality of life.
