Study Rundown: One of the most common approaches to the treatment of localized esophageal carcinoma is either chemoradiotherapy followed by surgery (aka trimodality therapy) or definitive chemotherapy (bimodality therapy, BMT).
At the conclusion of this retrospective cohort study of over 270 esophageal cancer patients, the authors found that local recurrence occurred in 23.2% (n=64) of patients, with the greatest risk of local recurrences occurring 2-3 years following BMT. In-Depth [retrospective cohort]: This retrospective cohort study included a total of 276 patients with esophageal cancer who were treated with definitive bimodality chemotherapy (BMT).

When you are told you have esophageal cancer and begin looking for treatment options, you may be concerned about life expectancy and quality of life. How do you decide where to go for treatment after you have been diagnosed with esophageal cancer? The chart below shows the survival results of 50 advanced-stage esophageal cancer patients who were diagnosed between 2004 and 2008.
Survival rates are also meaningful when compared to the results of other treatment centers.
As an alternative, we asked the independent biostatistician to analyze and compare our survival statistics to national cancer survival statistics that are gathered by the National Cancer Institute (NCI). The chart below shows the survival results of 37 advanced-stage esophageal cancer patients who were diagnosed between 2000 and 2005. As you study the chart, it's important to remember that the estimated CTCA survival rates were based on a relatively small sample of 37 advanced-stage esophageal cancer patients and therefore were subject to a high degree of variation.
The chart below shows the cancer survival rates for a group of 152 metastatic esophageal cancer patients who were diagnosed between 2000 and 2011.
Of the CTCA metastatic esophageal cancer patients shown in the above chart, the estimated survival rate at six months was 61%. At Cancer Treatment Centers of America, we understand that you may also wish to see the survival rates of the group of patients with distant (also referred to as metastatic) esophageal cancer reported in the Surveillance, Epidemiology and End Results (SEER) database of the National Cancer Institute. Therefore, we asked an independent biostatistician to analyze both the survival rates of the group of CTCA patients and the group of patients included in the SEER database. The objective of this analysis was to see how long each group of patients survived after their diagnosis. This analysis included esophageal cancer patients from CTCA who were diagnosed from 2000 to 2011 (including 2000 and 2011) with primary tumor sites (as coded by ICD-O-2 (1973+)) from C150 to C159, and were considered analytic cases by the CTCA. Primary tumor sites (as coded by ICD-O-2 (1973+)), date of initial diagnosis, date of last contact, year of initial diagnosis, age of initial diagnosis, gender, vital status, and cancer histologic type as coded by the ICD-O-3. The database from the CTCA cohort was prepared by the CTCA cancer registrars from the following four hospitals: Southwestern Regional Medical Center hospital, Midwestern Regional Medical Center hospital, Eastern Regional Medical Center hospital, and Western Regional Medical Center hospital. The SEER program of the National Cancer Institute is an authoritative source of information on cancer incidence and survival in the United States. This analysis included esophageal cancer patients from the latest SEER Limited-Use Database (as of 2014) who were diagnosed from 2000 to 2011 (including 2000 and 2011) with primary tumor sites (as coded by ICD-O-2 (1973+)) from C150 to C159. Primary tumor sites (as coded by ICD-O-2 (1973+)), survival time recode as calculated by the date of initial diagnosis and the date of death or the follow-up cutoff date, year of initial diagnosis, age of initial diagnosis, gender, vital status, and cancer histologic type as coded by the ICD-O-3.
In order to make a meaningful survival analysis, basic cancer and patient characteristics such as age at initial diagnosis, year of initial diagnosis, cancer stages, cancer primary sites, and gender were first analyzed for both the CTCA and SEER samples. For example, if a specific primary tumor site had patients in only one database, none of those patients were used in the analysis.
The survival outcome from the CTCA database was defined as the time from the initial diagnosis to death and computed in number of years as the difference between the date of death and the date of initial diagnosis divided by 365.25. For each survival outcome from each database, the survival curve, defined as the probability of cancer patient survival as a function of time after the initial diagnosis, was estimated by the nonparametric product-limit method[1]. Covariates such as age at initial diagnosis and year of initial diagnosis could affect the survival of esophageal cancer patients.

In part because the nature of the disease has changed, nearly 50 percent of patients with esophageal cancer that undergo an advanced surgical procedure now survive for five years, not 20 percent as once thought, as per an article reported in the April edition of the Journal of the American College of Surgeons. Whether surgery, chemotherapy, radiation, or some combination of them should be the standard of care has been debated for years. In the past, the typical esophageal cancer patient had the kind of cancer caused by smoking (squamous cell carcinoma) and was frequently terminal.
The shift toward earlier diagnosis of esophageal cancer can be explained by the relationship of adenocarcinoma to gastroesophageal reflux disease (GERD). The increasing prevalence of GERD has resulted in the establishment of Barrett's surveillance programs and the increasing likelihood that a given patient with severe heartburn will undergo endoscopy, an imaging test that can catch cancer early. Along with younger patients with less advanced cancer, better surgery is contributing to longer survival, as per the new study.
While still controversial, the authors argue that their results add to a growing body of evidence that removing the lymph nodes, while not helpful in breast cancer, does indeed improve survival rates in esophageal, gastric and rectal cancer.


While more effective, en bloc resection is used less often used due to its complexity, and the training involved.
The study also found that the number of patients with esophageal cancer now receiving chemotherapy and radiation more than doubled during the ten years during which data was examined, despite a lack of evidence supporting improved survival.

In recent years, women, particularly younger women, experienced larger improvements in hospital mortality after myocardial infarction than men, according to a new study. Scientists at the California NanoSystems Institute at UCLA have taken a major step toward confirming an unusual theory of how some cancer cells metastasize. Computers can be trained to be more accurate than pathologists in assessing slides of lung cancer tissues, according to a new study by researchers at the Stanford University School of Medicine. Using technology they developed, UT Southwestern Medical Center researchers have identified a previously unknown role of a certain class of proteins: as regulators of gene activity and RNA processing.
More than 13 million pain-blocking epidural procedures are performed every year in the United States. The use of salvage surgery in locoregional recurrence of esophageal cancer following chemoradiotherapy demonstrated significantly increased survival compared to those who were unable to undergo salvage surgery. Previous studies have found that patients on BMT experience frequent local relapses, which may be treated with salvage surgical therapy.
Of the patients with local recurrence, 36% (n=23) of patients underwent salvage surgery therapy. The primary outcomes were local relapse and distant metastases, and the salvage treatment for patients with local relapse only. At Cancer Treatment Centers of America® (CTCA), we believe you have the right to know our statistics for esophageal cancer treatment outcomes, so you can choose the best cancer care for you and your family. At Cancer Treatment Centers of America (CTCA), we believe that knowing the survival rates of esophageal cancer patients who are treated at our hospitals is one of the things that can help you and your family as you make this decision. This means that six months after their diagnosis, nearly 66% of the patients in this group were still alive.
Unfortunately, most hospitals and treatment centers don’t make their survival statistics available to the public. This database is called the NCI Surveillance, Epidemiology, and End Results Program, or SEER, for short.
Because the SEER database did not provide staging information for patients diagnosed in 2004 and 2005, the SEER sample includes only those patients diagnosed between 2000 and 2003.
Therefore, we asked an independent biostatistician to analyze the survival results of CTCA® patients. This means that six months after their diagnosis, 61% of the patients in this group were still living.
SEER is a source of population-based information about cancer incidence and survival in the United States that includes the stage of cancer at the time of diagnosis and patient survival data. Our fifth hospital, located near Atlanta, Georgia, was not included because it was not open to patients until August 2012. The independent biostatistician computed the survival outcomes of metastatic esophageal cancer patients from the CTCA database and metastatic esophageal cancer patients from the SEER database who were diagnosed between 2000 and 2011.
These factors significantly reduced the size of the CTCA sample, which means that the estimates reflected in the survival chart may be subject to high variation and may not be replicated in the future when we have a larger CTCA sample for analysis. Not all cancer patients who are treated at a CTCA hospital may experience these same results. More specifically, the SEER Limited-Use Database contained a combination of three databases. The survival outcome from the SEER database was provided by the SEER Limited-Use Data File as the number of completed years and the number of completed months. Formal statistical analyses of the esophageal cancer survival distributions between the CTCA database and the SEER database were conducted by the nonparametric logrank test and Wilcoxon test as well as the likelihood ratio test[1]. Similar estimates were also computed to estimate the difference of the survival rates at these time points between the two cohorts. Therefore, additional adjusted analyses were completed on the survival outcomes between the CTCA and SEER samples after adjusting for the effects of these covariates.
First, although a large cancer sample was available from the SEER program across many geographic regions in the United States, both samples, including the sample from CTCA, are convenience samples. Scientists at the University of Rochester Medical Center contend that earlier diagnoses, more widespread screening and individualized care have made surgery by far the best way to combat esophageal cancer as it is most often diagnosed today. Until recently, surgery has been considered the gold standard, but its role has been questioned by some medical oncologists based on their assumption that surgery comes with a high risk of complications and small chance of survival. At the point where the esophagus empties into the stomach, a ring of muscle keeps stomach acid used in digestion from flowing back up into the esophagus. Of those people with frequent heartburn for five years or more, about one in five develop Barrett's esophagus, giving them a 40-fold higher than normal risk of developing GERD-associated adenocarcinoma. The combination of the rise in GERD, the drop in smoking, and better diagnostics means that esophageal cancer is often found earlier, and increasingly, while still confined to the esophagus. Statistical analysis of patient survival found that en bloc esophagectomy, an operation that completely removes the cancer along with nearby lymph nodes, results in 30 percent fewer cancer deaths than a transhiatal resection, a surgery that leaves the lymph nodes in place. Refinements in operative technique and postoperative care have made en bloc resection much safer as well, scientists said.


Based on the current study, medical center scientists are calling for more widespread use of the technique, especially in those whose tumor is detected early.
One past study found that radiation and chemotherapy are not beneficial in early stage cancer, and may indeed harm patients when side effects are taken into account. Therefore, we asked an independent, third-party biostatistician to analyze the survival results of patients who were treated at CTCA. When they do, the results are not always consistently presented, so objective comparisons are difficult.
This, among other factors, means that the estimates reflected in the survival chart may not be replicated in the future when a larger CTCA sample is available for comparison.
SEER collects information on cancer incidence, prevalence and survival from specific geographic areas that represent 28% of the population of the United States. In both cases, the patients had been diagnosed with distant (metastatic) cancer as discussed above.
The SEER Program is a comprehensive source of population-based information in the United States that includes stage of cancer at the time of diagnosis and patient survival data. Patients whose age at initial diagnosis fell into the overlap of the two ranges from the CTCA and SEER samples were included in the survival analysis.
These were then converted to the number of years by dividing the number of total months by 12.
Because the estimated survival curves might not estimate the survival probability at these specific time points, survival rates from the closest observed survival times were used. The nature of these convenience samples prevents a causal interpretation of the statistical inferences.
In a number of cases today, oncologists will try chemotherapy and radiation first, completely avoiding surgery. Today, the average patient is younger, diagnosed earlier with a different kind of cancer (adenocarcinoma) and more likely to be cured. For a number of people, the ring malfunctions consistently over time, allowing acid to irritate the cells lining the esophagus, which causes "heartburn" pain and GERD.
While most cancer rates are falling, esophageal cancer has increased dramatically in recent years to become the fastest-growing type in the United States. These patients are the best candidates for surgery to completely remove the tumor and cure it. Scientists believe en bloc resection is more effective because it has a better chance of completely removing the cancer to control the disease at the tumor site. Scientists say future work will need to compare survival in patients receiving nonsurgical therapy to survival in patients who have had surgery. The purpose of this study was to evaluate the timing and outcome of patients undergoing active surveillance following BMT for esophageal cancer.
This was the largest cohort of BMT patients to date and the findings provide strong support for the use of salvage therapy for patients with local recurrence following BMT and also support the role of vigilant surveillance for at least 24 months following definitive therapy.
This means the cancer that had traveled from the primary site (esophagus) to one or more distant sites in the body where it continued to grow.
For these patients who were still alive or lost to follow-up at the time of entering the databases, their survival time was treated as statistically censored[1] at the difference between the date of last contact and the date of initial diagnosis. Because five-year survival rates have been popularly used in many cancer survival reports, five-year survival curves were also obtained by treating those who survived more than five years after the initial diagnosis as statistically censored at five years. Second, although some types of matching, as described above, were implemented to select the appropriate SEER and CTCA comparison samples, the distributions of important covariates such as age at initial diagnosis, race and year of initial diagnosis were not exactly the same between the CTCA sample and SEER sample. Authors of the current study argue that the information used to make those decisions is dated, and that the surgery is the most effective approach in a number of patients. Our study found that the five-year survival of patients after surgical resection for esophageal adenocarcinoma is better than that reported for any other form of treatment," said Peters, co-author of the journal article.
Acid can also cause long-term changes in the esophageal cells that make them pre-malignant, with the patches of abnormal cells known as Barrett's esophagus. However, no cost analysis was performed, which may reduce the feasibility of a vigilant surveillance program. 91% and 98% of local recurrences occurred within 2 and 3 years following BMT, respectively.
Because patients surviving more than five years remained part of the risk sets in the estimation of survival rates at any time within five years of diagnosis, the truncated survival curves were identical to the first portion of the complete survival curves. Hence, even with the adjusted analysis, the possible confounding of these factors to the analyses and results cannot be ruled out.
Another Cox proportional hazards model was also used to simultaneously adjust for the effects of both covariates (age at diagnosis and year of initial diagnosis) in the survival analysis.
Third, the survival analyses were based on the statistical comparisons of the rate of death from all possible causes, not solely the cancer-specific death.
Data from CTCA are not available for a statistical comparison on cancer cause-specific death rates.
