Current and ongoing progress in the therapy for resectable esophageal cancer

There have been recent advances in the surgical approach to respectable esophageal cancer. In addition, despite the paucity of level 1 data, regardless of histology (squamous cell or adenocarcinoma), neo-adjuvant chemoradiotherapy has evolved into a de facto standard of care for resectable disease. Pathologic response rate is a surrogate for a more favorable outcome. In addition, there are a number of molecularly targeted agents that may have clinical utility for these patients. Current clinical trials have been designed with a translational research component to define which patients may benefit from the incorporation of these novel agents alongside standard combined-modality approaches.     

Clinical significance of preoperative and postoperative cytokeratin 19 messenger RNA level in peripheral blood of esophageal cancer patients

The purpose of this study is to analyze the correlation between preoperative/postoperative Cytokeratin 19 (CK19) messenger RNA (mRNA) level in peripheral blood (PB) and the clinical significance in esophageal cancer patients with different clinicopathological factors. We detected the preoperative and postoperative CK19 mRNA level in the PB of 139 esophageal cancer patients who underwent complete resection and evaluated its clinical significance. We found that both the preoperative and postoperative CK19 mRNA level increased in the esophageal cancer patients with lymph node metastasis, relapse or distant metastasis compared with that in cancers without lymph node metastasis, relapse or distant metastasis. High postoperative CK19 mRNA levels indicate a short disease‐free survival (DFS) for the whole cohort esophageal cancer patients, whereas the high preoperative CK19 mRNA levels only indicate a short DFS for the esophageal cancer patients with squamous cell carcinoma, TNM III stage, and lymph node metastasis. The dynamic change of CK19 mRNA levels could indicate the prognosis of esophageal cancer patients. The patients with decreasing CK19 mRNA level after surgery had good prognosis, and the patients with changeless CK19 mRNA level had poor prognosis. Taken together, CK19 mRNA levels could be a promising marker in assessing prognosis or assigning treatment for the esophageal cancer patients according to different clinicopathological factors.     

Palliative interventions and prognosis in patients with advanced esophageal cancer

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.     

Long-term and short-term evaluation of esophageal reconstruction using the colon or the jejunum in esophageal cancer patients after gastrectomy

SUMMARY.  For esophageal cancer patients, the gastric tube is the first choice as an esophageal substitute, with the colon or the jejunum being used when the stomach cannot be used. We retrospectively compared these two methods from the viewpoint of peri-operative complications and long-term bodyweight alteration. From 1998 to 2005 53 patients who had undergone subtotal esophagectomy due to thoracic esophageal cancers were given reconstruction with the colon (28 cases) or the jejunum (25 cases). Both intestines were reconstructed via the subcutaneous route and were anastomosed to the internal mammalian artery and vein for a supercharged blood supply. There was no difference in operating time and blood loss. Compared with the colon reconstruction group, the hospital stay of the jejunum reconstruction group was significantly shorter (65 days vs 45 days, P  = 0.0120) and the incidence of anastomotic leakage tended to be less (13 cases, 46% vs 6 cases, 24%, P  = 0.1507), while other operative morbidity did not differ between the two groups. Bodyweight loss, which is a serious postoperative sequela after esophagectomy, was less in the jejunum group than in the colon group, showing a significant difference at 12 months after surgery. Our retrospective study revealed the jejunum to be superior to the colon for the reconstruction after esophagectomy along with gastrectomy, with respect to anastomotic leakage and bodyweight loss. The next step will be to conduct a prospective large cohort study.

Outcomes from chemoradiotherapy for patients with esophageal cancer

Chemoradiotherapy is a widely used alternative treatment to surgical resection in certain patient groups with early esophageal cancer. The aim of this study was to retrospectively assess toxicity and outcome of patients treated with definitive chemoradiotherapy for early esophageal cancer at one institution. A retrospective analysis of all patients treated with chemoradiotherapy between February 2000 and December 2008 at a single tertiary center was performed with documentation of treatment given, toxicities recorded, and follow‐up and outcome data. Sixty‐two patients received chemoradiotherapy for esophageal cancer. There were 20 males and 42 female patients with an average age of 68 years. Histology revealed adenocarcinoma in 28 patients and squamous cell carcinoma in 34 patients. All patients were staged with a computerized tomography scan, endoscopic ultrasound and positron emission tomography scan. Selection criteria for chemoradiotherapy were unfit for surgery, upper esophageal squamous carcinoma, unresectable primary tumor, or patient choice. The majority of the patients received a combination of cisplatin and 5‐fluorouracil chemotherapy with 55 Gy in 25 fractions of radiotherapy. Grade 3 toxicities were recorded in 11% of the patients. Eleven patients suffered from local recurrence and a stent was required in nine patients. Radiation strictures occurred in 10 patients requiring dilation in four. Five patients required a radiologically inserted feeding gastrostomy. The median overall survival was 21 months. Patients with adenocarcinomas and those with squamous cell carcinoma had a similar median survival. Overall survival was 70% at 1 year, 48% at 2 years, and 26% at 3 years. This case series of patients treated with chemoradiation for localized esophageal cancer suggest a generally well‐tolerated treatment with survival rates after chemoradiotherapy comparable with those seen with surgery.

Intraoperative ultrasonography for the identification of thoracic recurrent laryngeal nerve lymph nodes in patients with esophageal cancer

The rate of vocal cord palsy following resection for esophageal carcinoma has increased due to lymphadenectomy around the recurrent laryngeal nerves (RLN). The aim of this pilot study was to assess the ability of intraoperative ultrasonography to detect thoracic RLN node metastases in patients with esophageal cancer. Intraoperative ultrasonography was performed during esophagectomy to assess whether RLN lymph nodes were metastatic in 10 patients with esophageal squamous cell cancer. All patients underwent RLN lymphadenectomy, and the nodes were assessed for metastasis. Three patients had pathological RLN lymph node metastases, of which one had right RLN node metastasis, and three had left RLN node metastases. For detecting right RLN lymph node metastasis, the sensitivity, specificity, and positive and negative predictive values of intraoperative ultrasonography were 100%, 33.3%, 14.3%, and 100%, respectively. For the detection of left RLN lymph node, these values were 100%, 85.7%, 75%, and 100%, respectively. This study suggests that intraoperative ultrasonography is feasible and safe to detect RLN lymph node metastases for patients with esophageal cancer. Further study will be performed to evaluate the validity and utility of this diagnostic technique.
