When you are told you have stomach 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 stomach cancer? The chart below shows the survival results of 50 advanced-stage stomach 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 a comparison between CTCA and SEER on the survival rates of advanced-stage stomach cancer patients who were diagnosed between 2000 and 2005. The differences in stomach cancer survival rates at six months are statistically significant. The differences in survival rates at 1 year and 1.5 years are not statistically significant at a 5 percent level. As you study stomach cancer statistics, it’s important to remember that the estimated CTCA survival rates were based on a relatively small sample of 44 advanced-stage stomach cancer patients and therefore were subject to a high degree of variation.
The chart below shows the cancer survival rates for a group of 179 metastatic stomach cancer patients who were diagnosed between 2000 and 2011. Of the CTCA metastatic stomach cancer patients shown in the above chart, the estimated survival rate at six months was 64%. At Cancer Treatment Centers of America, we understand that you may also wish to see the survival rates of the group of metastatic stomach cancer patients 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.
We also want to be sure you understand that cancer is a complex disease and each person’s medical condition is different; therefore, CTCA makes no claims about the efficacy of specific treatments, the delivery of care, nor the meaning of the CTCA and SEER analyses. This analysis included stomach 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 C160 to C169, 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 stomach 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 C160 to C169. 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 stomach cancer patients.

Lately it was more well-established the relationship between infection with Helicobacter pylori and gastric cancer. Low socioeconomic status may be a contributing factor, probably through diet and infection with Helicobacter pylori. Helicobacter pylori infection is increasingly shown to contribute to development of gastric cancer. Gastric resection in history, especially for gastric ulcer, is a risk factor for developing gastric cancer in longer than 15 years after resection.
Gastric ulcer, presents a low risk of malignancy, but often can be confused with an ulcerated gastric cancer, fact that requires biopsy of the lesion.
Quite often, gastric cancer can be discovered from an anemic syndrome with or without dyspeptic symptoms. Histologically, gastric cancer is a adenocarcinoma, which may appear as protruded, ulcerated or infiltrating cancer.
Extension to nearby organs of gastric cancer (pancreas, transverse colon), appears early in general, as well as lymphatic extension of it.
Most often the diagnosis start from dyspepsia, epigastric pain, weight loss or an unclear anemic syndrome. Physical exam is usually poor, but in advanced forms of gastric cancer is allowing the palpation of a epigastric mass or a subclavian adenopathy. From Histologically point of view, gastric cancer is classified as follows: incipient gastric cancer (superficial, affecting the mucosa and submucosa) and advanced gastric cancer (affecting all layers of stomach). Radiological examination with barium, a method that is outdated in terms of diagnosis, addressing in general to the advanced gastric cancer forms or gastric cancer infiltrating forms. Echo-endoscopy allows staging T (tumor) from TNM classification by assessing gastric parietal extension and the extension in regional lymph nodes. The prognosis depends on theTNM extension of gastric cancer, histological type and age of the patient. Dermatofibroma, otherwise known as benign fibrous histiocytomas, dermal dendrocytoma, Fibrous dermatofibroma, Fibrous histiocytoma, Nodular subepidermal fibrosis, and Sclerosing hemangioma, is a skin growth, considered benign.


Injury – Previous skin injuries such as thorn pricks or insect bites may lead to dermatofibroma. Appearance of any skin growths requires early diagnosis to rule out the presence of malignancies. Physical examination -Dermatofibromas are initially diagnosed by physical examination of the skin and the growth itself. Histological Examinations – When other symptoms occur such as, bleeding or change in color, a sample of the tissue is excised for biopsy purposes. Histological examinations may reveal a pseudoepethiliomatous hyperplasia which means there is a false epithelial growth on the skin.
Medical Care – Medical treatment only includes steroid injections to relieve any symptoms such as pain and itchiness.
Surgical Care – For disturbing dermatofibromas, such as in cases of pain and pruritus, the skin growth may be removed surgically. Excision Biopsy – Surgical removal involves excision of the entire skin growth including the subcutaneous layer underlying it. Cryosurgery – This involves the exposure of the skin growth to very cold temperature such as liquid nitrogen to freeze and remove the lump.
Laser Treatment – Carbon dioxide laser treatment can be done and has been reported to effectively remove the skin growth. Avoid too much exposure to the sun during periods from 10am to 3pm because exposure to ultraviolet rays may worsen the condition and trigger a malignancy.

Sindrome de Patau tambien conocido como Trisomia 13 o Trisomia D, es una anomalia cromosomica en la que el paciente tiene un cromosoma 13 adicional debido a la no disyuncion de los cromosomas durante la meiosis. La mayoria de los casos de sindrome de Patau son como resultado de la trisomia 13, lo que significa que cada celula del cuerpo tiene tres copias del cromosoma 13 en lugar de los habituales dos copias. Un pequeno porcentaje de los casos ocurre cuando solo algunas de las celulas del cuerpo tienen una copia extra, resultando en una poblacion mixta de celulas con un numero diferente de cromosomas, estos casos se denominan Mosaico de Patau. El tratamiento medico se planea caso por caso y depende de las circunstancias individuales del paciente, se centra en las particularidades fisicas de los problemas con los que cada nino nace, en orden de importancia. La cirugia puede ser necesaria para reparar los defectos cardiacos, labio leporino y paladar hendido. La terapia fisica, ocupacional y del habla le ayudara a personas con sindrome de Patau alcanzar su potencial de desarrollo completo, a pesar de los defectos neurologicos. Una manera de prevenir la trisomia 13 o el Sindrome de Patau es realizarse una prueba de cromosomas de celulas amnioticas cuando la madre esta embarazada. At Cancer Treatment Centers of America® (CTCA), we believe you have the right to know our statistics for stomach cancer treatment outcomes, so you can choose the best cancer care for you and your family. At CTCA, we believe that knowing the stomach cancer survival rates of 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, 69 percent 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, 64% 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 stomach cancer patients from the CTCA database and metastatic stomach 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 stomach 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.
Increased content of nitrosamines in food preserved by salt and smoke are factors favoring the development of gastric cancer, in exchange, diet rich in fruits and vegetables with increased content of vitamin A and vitamin C, protects the stomach. Helicobacter pylori has been classified by WHO as first order carcinogenic factor, is the first bacterium that is recognized to be involved in developing of a malignancy. Usually there is an inflammatory gastritis of gastric stump, which can degenerate malignant. Therefore, his discovery is often accidental, when performing an endoscopy for epigastric symptoms. The presence of family aggregation of gastric cancer or precancerous lesions, can draw attention to the diagnosis of gastric cancer.


It allows viewing of the lesions, assessing their character and taking multiple biopsies to confirm the histological diagnosis of gastric cancer. Recent studies have suggested that preoperative application of chemotherapy followed by chemo-radiotherapy, cause a major histologic response which can lead to a increased survival rate. The skin growth is usually round and brownish to purple in color and feels like a hard lump in the skin.
Dermatofibroma has a persistent nature which makes other researchers believe that it is a neoplastic process rather than a reaction. The condition is usually asymptomatic, but others may experience pruritus (severe itching) and tenderness. The lump is examined using a microscope to determine the characteristics of the cells and if they are benign or malignant.
Due to this, it is important to seek medical advice whenever an abnormal skin growth appears. Being normally benign, it can be left in place and ignored, but reassurance is important for patients. Presence of indefinite histologic examinations may also require this in order to remove any cells that may be malignant. Just like superficial shaving, the lump may also reoccur and may require another treatment for removal.

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.
Fact that over a decade has passed to eradicate Helicobacter pylori infection, makes that gastric cancer incidence to be lower.
Helicobater pylori intervention in gastric cancer development is achieved by inducing an atrophic gastritis with intestinal metaplasia, which has an evolutionary potential to dysplasia and finally to the development of gastric cancer. This makes the patient with stomach surgery, to be watched endoscopic more than 15 years after the surgery. Ulcerated gastric cancer may be confused endoscopically with gastric ulcer and therefore biopsy is needed to differentiate them. Surgery, with intent to eradicate gastric cancer is possible only in one third of cases, and in these survival at 5 years is about 25%. Dermatofibroma is also called fibrous histiocytoma because there is a growth of dendritic histiocyte cells that are normally non-cancerous. However, ruling out malignancies is only done because some symptoms of dermatofibromas are similar to that of other skin malignancies. However, for aesthetic purposes, particularly for female patients, there are surgical or medical treatments to remove the lesion. However, this procedure increases recurrences because the lesion is not removed from within.
This means the cancer had traveled from the primary site (stomach) to one or more distant sites in the body where it continued to grow. All comparative survival analyses were conducted separately for the mild to moderate cancer stage and the advanced cancer stage (defined by the SEER Summary Stage of 7) using patients from the CTCA and SEER databases.
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.
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 analyses, 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.
