Ovarian cancer ranks 5th in cancer deaths among women, accounting for more deaths than any other cancer of the female reproductive system. When you are told you have ovarian 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 ovarian cancer?
The chart below shows the survival results of 25 advanced-stage ovarian 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 ovarian cancer rates 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, ovarian 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 28 advanced-stage ovarian cancer patients and therefore were subject to a high degree of variation.
The chart below shows the cancer survival rates for a group of 126 metastatic ovarian cancer patients who were diagnosed between 2000 and 2011. Of the CTCA metastatic ovarian cancer patients shown in the above chart, the estimated survival rate at six months was 93%.
At Cancer Treatment Centers of America, we understand that you may also wish to see the survival rates of the group of metastatic ovarian 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 ovarian cancer patients from CTCA who were diagnosed from 2000 to 2011 (including 2000 and 2011) with a primary tumor site (as coded by ICD-O-2 (1973+)) of C569, 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 ovarian cancer patients from the latest SEER Limited-Use Database (as of 2014) who were diagnosed from 2000 to 2011 (including 2000 and 2011) with a primary tumor site (as coded by ICD-O-2 (1973+)) of C569. 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, and cancer primary sites 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 ovarian cancer patients.

Lung Cancer - Did you know that lung cancer is the leading cause of cancer death in the United States? Expand All Collapse AllLifetime risk estimates are not available with the current statistics release, but will be added later when population data for older age groups are available. Prevalence of This Cancer: In 2013, there were an estimated 415,707 people living with lung and bronchus cancer in the United States. How Many People Survive 5 Years Or More after Being Diagnosed with Lung and Bronchus Cancer? Relative survival statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. The earlier lung and bronchus cancer is caught, the better chance a person has of surviving five years after being diagnosed. In 2016, it is estimated that there will be 224,390 new cases of lung and bronchus cancer and an estimated 158,080 people will die of this disease. Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.
Using statistical models for analysis, rates for new lung and bronchus cancer cases have been falling on average 1.8% each year over the last 10 years. There are two main categories of lung cancer: non-small cell lung cancer and small cell lung cancer. Adenocarcinoma: Cancer that begins in the cells that line the alveoli and make substances such as mucus. Other less common types of non-small cell lung cancer are: pleomorphic, carcinoid tumor, salivary gland carcinoma, and unclassified carcinoma. There are two main types of small cell lung cancer, again according to cell type: small cell carcinoma (oat cell cancer) and combined small cell carcinoma. All statistics in this report are based on statistics from SEER and the Centers for Disease Control and Prevention's National Center for Health Statistics.

The statistics presented in this factsheet are based on the most recent data available, most of which can be found in the SEER Cancer Statistics Review. Survival rates for ovarian cancer have almost doubled over the last thirty years, as we pointed out in our press release last week. Our statisticians have looked at data on ovarian cancer rates around the country and estimated that in England and Wales, 1,000 more women are now surviving the disease every year, compared with the early 70s.
But with all silver linings, there’s often a cloud nearby – survival rates for women with more advanced disease haven’t improved by nearly as much as it has for those whose disease is caught early. The new statistics also highlight the urgent need for better treatments for those women who are diagnosed at a later stage. Another feature of ovarian cancer (as with many cancers), is that survival rates for the disease vary greatly according to how early the disease is diagnosed. For example, according to data from the Anglia Cancer Network, if you follow 100 women diagnosed with the earliest stage of ovarian cancer for five years, on average more than 90 will have survived their disease. As you can see, most of the overall change is due to the large increase in survival among women diagnosed with stage II disease. There are several possible reasons why we’re seeing the increase in survival, but two stand out.
Firstly, chemotherapy for the disease has improved – in particular, there’s now widespread access to a drug called carboplatin, which Cancer Research UK scientists developed. But the improvement’s also linked to the introduction of specialised gynaecological surgeons, who regularly operate on diseases like ovarian cancer, and who tend to have a better success rate than general surgeons. As well as these improvements in treatment, there’s also the possibility that at least some of the change is due to improvements in the way the disease is classified.
The main type is known as ‘high-grade serous’ ovarian cancer, and this makes up the majority of cases. It now seems that these cancers are driven by a very distinct set of defective genes – including, in about a quarter of cases, a pair of genes known as BRCA1 and BRCA2, which are infamous for their role in inherited breast cancers. As regular readers of this blog will know, new types of cancer drug, collectively called PARP inhibitors are generating a lot of excitement in the research community. Most of the trials carried out so far have looked at whether PARP inhibitors can treat women with breast cancer caused by inherited BRCA gene faults, who make up about five per cent of breast cancer cases. According to Cancer Research UK’s ovarian cancer expert Dr James Brenton, one intriguing possibility is that these women could first be given a platinum drug for a short period, and then longer term PARP inhibitor treatment to ‘mop up’ any remaining cancer cells.
This is a strategy that a team of researchers led by Professor Jonathan Lederman at UCL has been testing in a clinical trial.
But along with trying to improve treatments, diagnosing ovarian cancer earlier will also save lives. We’re supporting several efforts to do this: the huge UKCTOCS screening trial we wrote about in 2009 is continuing to gather data and researchers worldwide are investigating new ways to detect and monitor the disease. To this end, we’ve just awarded Professor Ian Jacobs, one of the leading UK experts in ovarian cancer detection, a five-year programme grant to investigate new molecular tests (biomarkers)  for early ovarian cancer. And at some point in the not-too-distant future, we hope the fruits of this research will mean that the outlook for women diagnosed with ovarian cancer, at any stage, will be a good deal brighter than it is now.

Like all cancers, ovarian cancer represents a change in the normal behavior of the cells within the organ such that they begin to grow and divide uncontrollably. When ovarian cancer is found, the malignant tumor is removed and likely to be followed up with chemotherapy treatments. At Cancer Treatment Centers of America® (CTCA), we believe you have the right to know our statistics for ovarian 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 ovarian 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 92 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, 93% 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 ovarian cancer patients from the CTCA database and metastatic ovarian 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 ovarian 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.
SEER currently collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 28 percent of the U.S.


Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient.
In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). Because these statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient.
And crucially, we need to find a way to treat women whose cancers have become resistant to their initial therapy.
According to the latest figures, more than 6,500 women are diagnosed with the disease every year, and around 4,400 die. But if you take 100 women diagnosed with the most advanced stage of ovarian cancer, when it has spread to distant parts of the body, only five or six will have done so.
Carboplatin offered doctors not just a better treatment for women initially diagnosed with the disease, but a better way to manage the disease if it came back. In particular, it’s possible that better surgeons have collected better quality staging data – and ovarian cancers that might have been mistakenly classified as ‘early’ are now properly classified as later stage disease.
For instance, it’s now becoming apparent that what we call ‘ovarian cancer’ is in fact at least three distinct – and very different – diseases.
Evidence is now emerging that these cancers may not even start in the ovaries, but instead originate in the cells that make up the fallopian tubes. The remainder of cases are made up of a fourth form, called mucinous cancer, and others that are impossible to classify). PARP inhibitors have been carefully designed to treat cancers driven by faulty BRCA genes, and Cancer Research UK scientists have been instrumental in their development. Finding that faulty BRCA 1 and 2 genes are common in serous ovarian cancer is exciting, and means that that these drugs may ultimately be useful for women with this form of the disease. As PARP inhibitors can be taken as tablets (rather than intravenously), this would be especially convenient as an outpatient treatment. Research going on right now, in labs around the UK, could lead to even greater improvements in our understanding of ovarian cancer – both how to treat it, and how to detect it earlier.
There is no douubt now that HRT (hormone replacement therapy) increases the risk of breast cancer. We also highlight other relevant material, debunk myths and media scares, and provide links to other helpful resources. There are approximately 22,000 cases of ovarian cancer (all subtypes) annually in the United States, which accounts for about 3% of all women’s cancers. The survival rate of ovarian cancer depends on if and how extensively the cancer has spread beyond the ovaries. These are the most common type of ovarian cancerous tumors, accounting for about 80% – 88% of ovarian cancers. Therefore, we asked an independent, third-party biostatistician to analyze the ovarian cancer survival rates 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. No two patients are entirely alike, and treatment and responses to treatment can vary greatly. This factsheet does not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although it provides links to information in many of these areas. Combination HRT ( progestins and estrogens) are the same in action as combined oral contraceptives and therefore also increase the risk of ovarian cancer.
Finding ovarian cancer at an early stage can lead to a much higher success rate in treatment.
Other types include germ cell tumors, which start from cells that produce ova (the eggs), and stromal tumors, which form from the cells that hold ovaries together and produce female hormones. This means the cancer that had traveled from the primary site (ovary) 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.
It is been unfortunate that flawed Pill studies have mistakenly clamied prevention due to lack of control women who had never taken hormones for any reason. Unfortunately, ovarian cancer often goes undetected until it has spread and becomes more difficult to treat.
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.
