Is small cell lung cancer more treatable?
Small cell lung cancer can grow quickly and affect the brain, bones and liver and adrenal glands . Small cell lung cancer that spreads is treatable but generally isn't curable. Other complications include: Pleural effusion (fluid buildup in the area outside of the lungs).
Can small cell lung cancer go into remission?
Chemotherapy is the keystone in the treatment of small cell lung cancer (SCLC). Objective remission and good palliation is achieved in ∼80% of the patients, but the remissions are in general short (mean <1 yr), and few are cured.
Is small cell lung cancer always terminal?
People with small-cell lung cancer in the advanced stage cannot be cured. They usually survive less than one year. Treatment may be moderately successful for people with limited-stage disease. However, even with limited-stage disease, the median survival time is less than two years.
How long does it take small cell lung cancer to spread?
Given the neuroendocrinological origin of SCLC, it is considered the prototype of rapidly growing malignancies with doubling time in the range of 25 to 217 days according to several studies. A described by Wang et al, the doubling time of SCLC ranges from 54–132 days.
What is the most common treatment for small cell lung cancer?
Chemotherapy. Chemotherapy is the primary treatment for SCLC because of how quickly the disease can spread. Chemotherapy is the use of drugs to destroy cancer cells, usually by keeping the cancer cells from growing, dividing, and making more cells.
How well does chemo work on small cell lung cancer?
Chemotherapy with or without immunotherapy still offers a high rate of response, with 60 to 80 percent of patients having significant tumor shrinkage and 10 to 15 percent achieving a complete response. The use of maintenance immunotherapy may prolong treatment response and survival in some people.
What is the newest treatment for lung cancer?
Atezolizumab is approved to treat some people with non-small cell lung cancer after surgery. An immune checkpoint inhibitor is a drug that blocks proteins on immune system cells which then allows them to fight cancer.
How long does chemo prolong life in small cell lung cancer?
A trend in survival benefit was seen in the patients with ES-SCLC, with a median survival of 6.5 months in the cyclophosphamide, epirubicin and vincristine group compared to 8.4 months in the EP group.
Where does small cell lung cancer spread first?
Most lung cancers first spread to lymph nodes within the lung or around the major airways.
Which type of lung cancer has the best prognosis?
Adenocarcinoma is usually found in the outer parts of the lung and is more likely to be found before it has spread. People with a type of adenocarcinoma called adenocarcinoma in situ (previously called bronchioloalveolar carcinoma) tend to have a better outlook than those with other types of lung cancer.
What is the most fatal type of lung cancer?
SCLC is the most aggressive form of lung cancer.
Which is worse small cell or large cell lung cancer?
Some types are more aggressive than others, but generally, small cell cancer is more aggressive than non-small cell lung cancer.
Is small cell lung cancer aggressive?
Like all cancers, SCLC begins at the cellular level and causes abnormal cells in the lungs to reproduce rapidly and uncontrollably. SCLC usually begins in the airways of the lung, and quickly spreads to other areas of your body. SCLC is the most aggressive form of lung cancer.
Where does small cell lung cancer spread first?
Most lung cancers first spread to lymph nodes within the lung or around the major airways.
Why is SCLC so aggressive?
And when they experimentally increased or lowered its activity in cancer cell lines, it altered the ability of the cancer cells to metastasize. They researchers think that these PLCG2-high cells could be part of the explanation for SCLC's aggressiveness.
How long can you live with lung cancer?
SCLC can grow and spread quickly. And according to statistics, the likelihood of living for five years after you've been diagnosed with SCLC is between 3% and 27%, depending on how advanced the cancer is when it's found. 1

Some of the variables that impact SCLC patients include: 10 . The stage and spread of cancer: Limited stage SCLC has a better chance for long-term survival than extensive-stage SCLC. Spread to the brain and liver, in particular, are associated with poorer prognoses. Your age: Younger people tend to live longer than older adults after their ...
What is the best treatment for SCLC?
Chemotherapy with radiation therapy, which uses high-energy radiation to kill cancer cells and shrink tumors, is considered the standard course of care for SCLC patients. This combined treatment regimen has been shown to improve survival by about 5% over chemotherapy alone. 6 .
What are the divisions of cancer?
These divisions break down into four basic categories: 7 . Localized: Cancer is limited to the area where it originated and has not spread. Regional: Tumors have spread to nearby lymph nodes, tissues, or organs. Distant: Tumors have spread to distant parts of the body .
What is the stage of cancer that spreads to other parts of the body?
Extensive-stage: At this advanced stage, cancer has metastasized (spread) to other parts of the body, such as the other lung, brain, liver, adrenal glands, and bones.
How does chemotherapy improve survival?
Chemotherapy improves the survival of patients with limited-stage disease (LD) or extensive-stage disease (ED), but it is curative in only a minority of patients. [ 1, 2] Because patients with SCLC tend to develop distant metastases, localized forms of treatment, such as surgical resection or radiation therapy, rarely produce long-term survival. [ 3] With incorporation of current chemotherapy regimens into the treatment program, however, survival is prolonged, with at least a fourfold to fivefold improvement in median survival compared with patients who are given no therapy.
How long does it take to recover from second line chemo?
Although second-line chemotherapy has been shown to produce tumor regression, responses are usually short lived; the median survival is rarely more than 12 months and usually less than 6 months after second-line therapy . [ 1] Response to first-line chemotherapy predicts for subsequent response to second-line therapy.
What percentage of bronchogenic carcinomas are caused by SCLC?
SCLC accounts for approximately 15% of bronchogenic carcinomas.
Why is staging important for SCLC?
Staging procedures for SCLC are important to distinguish patients with disease limited to their thorax from those with distant metastases. At the time of initial diagnosis, approximately two-thirds of patients with SCLC have clinical evidence of metastases; most of the remaining patients have clinical evidence of extensive nodal involvement in the hilar, mediastinal, and sometimes supraclavicular regions.
What are the risk factors for lung cancer?
Other risk factors for lung cancer include the following: History of or current tobacco use: cigarettes, pipes, and cigars. [ 4] Exposure to cancer-causing substances in secondhand smoke. [ 5, 6] Occupational exposure to asbestos, arsenic, chromium, beryllium, nickel, and other agents.
Is SCLC more responsive to radiation?
SCLC is more responsive to chemotherapy and radiation therapy than other cell types of lung cancer; however, a cure is difficult to achieve because SCLC has a greater tendency to be widely disseminated by the time of diagnosis.
Has SCLC decreased?
The overall incidence and mortality rates of SCLC in the United States have decreased during the past few decades. [ 2]
Types of Radiation Therapy
To understand success rates when treating lung cancer with radiation therapy, it's important to look at the different methods/types of radiation and the goals of treatment. Radiation therapy has changed considerably in recent years and has become much more effective and precise (fewer side effects) than in the past.
Small Cell Lung Cancer (SCLC) Success Rate
Small cell lung cancer accounts for roughly 13% of lung cancers and tends to spread early (often to the brain) and aggressively. 10 Roughly one-third of these cancers are diagnosed when they are considered "limited stage" tumors, and two-thirds are already extensive at the time of diagnosis. 11
Non-Small Cell Lung Cancer (NSCLC) Success Rate
The effects of treatments for non-small cell lung cancer are reported in different ways. In some cases, these are divided by the four stages of the disease. In others, they are roughly broken down into three stages: local tumors (stage 1 and some stage 2 tumors), regional (some stage 2 and some stage 3 tumors), and distant (stage 4 lung cancer).
Influencing Factors
There are a number of factors that can influence the success rate of radiation therapy, and it's important to keep these in mind when looking at general statistics that compare people as a whole.
Side Effects
As with any cancer treatment, radiation therapy can have side effects and adverse reactions at times. Some of these include:
Talk to Your Healthcare Provider
There is a lot of information to digest simply looking at the role of radiation therapy in the different types and stages of lung cancer, but individual differences are crucial as well. Every person is unique, and every lung cancer is different in some way.
Summary
Radiation therapy may be used for nearly any type or stage of lung cancer, but treatment goals differ. In early-stage lung cancer, radiation may be used in an attempt to cure the cancer. In this case, specialized radiation called stereotactic body radiotherapy (SBRT) may be as effective as surgery in some settings.
How to learn more about clinical trials?
If you would like to learn more about clinical trials that might be right for you, start by asking your doctor if your clinic or hospital conducts clinical trials.
Why do we do clinical trials?
Clinical trials are carefully controlled research studies that are done to get a closer look at promising new treatments or procedures . Clinical trials are one way to get state-of-the art cancer treatment. In some cases they may be the only way to get access to newer treatments. They are also the best way for doctors to learn better methods to treat cancer. Still, they're not right for everyone.

What is the best treatment for cancer in the lungs?
If cancer growth in the lungs is causing symptoms such as shortness of breath or bleeding, radiation therapy or other types of treatment, such as laser surgery, can sometimes be helpful. Radiation therapy can also be used to relieve symptoms if the cancer has spread to the bones, brain, or spinal cord.
What to do if you have only one small tumor in your lung?
If you only have one small tumor in your lung and there is no evidence of cancer in lymph nodes or elsewhere, your doctors might recommend surgery to remove the tumor and the nearby lymph nodes.
What happens if cancer grows back?
If the cancer continues to grow during treatment or comes back, any further treatment will depend on the location and extent of the cancer, what treatments you’ve had, and on your health and desire for further treatment. It’s always important to understand the goal of any further treatment before it starts. You should understand if it’s to try to cure the cancer, to slow its growth, or to help relieve symptoms. It is also important to understand the benefits and risks.
What is the first treatment for SCLC?
If you have extensive SCLC and are in fairly good health, chemotherapy (chemo), possibly along with an immunotherapy drug, is typically the first treatment. This can often shrink the cancer, treat your symptoms, and help you live longer.
What is the treatment for chest cancer?
If you are in good health, the standard treatment is chemo plus radiation to the chest given at the same time (called concurrent chemoradiation ). The chemo drugs used are usually etoposide plus either cisplatin or carboplatin.
What to do if you smoke and have lung cancer?
If you smoke, one of the most important things you can do to be ready for treatment is to quit. Studies have shown that patients who stop smoking after a diagnosis of lung cancer tend to have better outcomes than those who don’t.

Why is it important to know the stage of lung cancer?
The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. Some of the tests used to diagnose small cell lung cancer are also used to stage the disease. (See the General Information section.)
What are the two parts of the lungs?
The lungs are a pair of cone-shaped breathing organs that are found in the chest. The lungs bring oxygen into the body when you breathe in and take out carbon dioxide when you breathe out. Each lung has sections called lobes. The left lung has two lobes. The right lung, which is slightly larger, has three. A thin membrane called the pleura surrounds the lungs. Two tubes called bronchi lead from the trachea (windpipe) to the right and left lungs. The bronchi are sometimes also affected by lung cancer. Small tubes called bronchioles and tiny air sacs called alveoli make up the inside of the lungs.
What should I do if I have lung cancer?
If lung cancer is found, patients should think about taking part in one of the many clinical trials being done to improve treatment .

How many people die from lung cancer in the world?
SCLC comprises an estimated 250,000 new cases and at least 200,000 deaths globally each year5. Lung cancer, including all histological subtypes, is more prevalent in high-income countries/regions, reflecting relative levels of tobacco consumption4,6. However, the specific incidence of SCLC in different countries/regions or continents is not well described. As with lung cancer in general, SCLC is most prevalent in men but the proportion of cases in women compared to men has risen worldwide over the past 50 years, again reflecting tobacco consumption trends7. SCLC incidence in the USA has been declining over the past three decades in parallel with the decreasing prevalence of cigarette smoking8. In the USA, the proportion of elderly patients with SCLC (>70 years of age) has increased from 23% in 1975 to 44% in 2010 (REF.9). Despite a higher prevalence of smoking in African-American men and women, SCLC is less prevalent in African-American individuals than in white Americans10,11.
What are the subtypes of SCLC?
Four major subtypes of SCLC are defined based on high levels of ASCL1 (SCLC-A subtype), NEUROD1 (SCLC-N), POU2F3 (SCLC-P) or YAP1 (SCLC-Y) 130. Subsequent analyses have suggested a division of SCLC-A into two clusters (SCLC-A and SCLC-A2) differing in their expression of HES1 (REF.131) and a rare subtype demonstrating elevated expression of the transcription factor ATOH1 (REF.79) (FIG. 3). Among other differences, these subtypes tend to reflect the differential expression of MYC family members, with increased MYCLexpression being associated with SCLC-A and increased MYCexpression occurring in the other subtypes. Data from both mouse models and clinical trials suggest that Aurora kinase inhibitors might be selectively effective in MYC-high SCLC44,132,133. Differences between the transcription programmes of these four subtypes include distinct degrees of neuroendocrine differentiation and differences in metabolism. This emerging molecular classification also serves as a framework within which to further refine additional subtypes131(FIG. 3). Importantly, single-cell analyses are likely to help define how intratumoural heterogeneity is connected to these and possibly new subtypes109,110. Analogous to the transition of lung adenocarcinoma to SCLC, an important aspect of future studies will be to monitor how SCLC tumours of certain subtypes evolve with time and treatment. Data from mouse SCLC cell lines suggest a possible developmental hierarchy among subtypes, with SCLC-A evolving to SCLC-N and subsequently to SCLC-Y134. Of note, mouse models generated to date only model the SCLC-A and SCLC-N subtypes130, and the development of new models combining various genetic alterations and different putative cell-of-origin types56will be key to modelling all subtypes, possibly helping to define new subtypes and to investigate intratumoural and intertumoural heterogeneity in SCLC.
How do SCLC cells communicate?
SCLC cells have the capacity to communicate with their microenvironment in an autocrine, paracrine and endocrine manner. Several studies suggest that neuropeptides produced by SCLC cells promote tumour cell survival and proliferation by autocrine and paracrine loops93–96. Autocrine KIT, Hedgehog and IGF1 signalling can enhance SCLC cell growth97–99and paracrine FGF signalling between neuroendocrine and non-neuroendocrine SCLC cells might promote survival and metastasis100. The presence of endocrine paraneoplastic syndromes in patients with SCLC101,102imply that long-range communication exists between SCLC cells and other cells in the body but it is unclear if these systemic effects have a role in SCLC growth. Overall, the extent of the molecules secreted by SCLC cells, the cell types reached by these molecules, and the effects of these interactions on tumour growth and response to treatment remain largely unknown.
What organs do sclc tumors grow to?
SCLC tumours growing in the lungs of genetically engineered mice often metastasize to the pleural space, lymph nodes and distant organs, including the liver, similar to what is observed in patients54. One notable exception is the lack of brain metastasis in SCLC mouse models, which might reflect either biological differences between human and mouse tumours or the relatively rapid death of mice from their primary tumours and liver metastases. The analysis of primary tumours and metastases in mouse models identified the transcription factor NFIB as a major determinant of SCLC metastasis112–114. NFIB levels are also elevated in human SCLC metastases compared with primary tumours112,113. One mechanism underlying the pro-metastatic role of NFIB in SCLC is by the induction of gene expression programmes related to cell adhesion, cell migration and neuronal differentiation90,112. Mechanisms other than NFIB remain poorly understood but factors associated with neuronal differentiation and migration are also implicated in SCLC metastatic potential83,115.
What genes are lost in SCLC?
Other early studies described the amplification of MYC family genes (MYC , MYCLand MYCN) in a subset of SCLC tumours27–29. These observations have been validated in DNA and RNA sequencing analyses of larger cohorts of primary tumours and of patient-derived and CTC-derived xenograft models24,30–33. These studies also identified other recurrent alterations (Table 1). Among the few that have been functionally validated in mouse models or cell culture assays are loss-of-function events in RB family members p107 and p130 (encoded by RBL1and RBL2, respectively)34–36, the tumour suppressor PTEN37,38, NOTCH receptors24,39,40and the chromatin regulator CREBBP41. In addition to recurrent amplification of MYC family genes42–44, amplification of FGFR1(encoding fibroblast growth factor receptor 1)45and GNAS(encoding the α-subunit of the heterotrimeric G protein Gs)46also occurs. The histone methyltransferase KMT2D (also known as MLL) is mutationally inactivated in 8% of SCLC tumours47. Importantly, primary tumours and patient-derived xenograft models often correspond to early stages of SCLC development, which may introduce a bias in the identification of genetic drivers. However, genetic analysis of more advanced cancers has, thus far, not identified new drivers, except possibly a role for WNT signalling in chemoresistant SCLC48.
How much response rate is there to cytotoxic therapy?
SCLC is initially exceptionally responsive to cytotoxic therapies — up to 25% of patients with early-stage SCLC achieve long-term control of disease with concurrent chemoradiotherapy (CRT) and response rates are consistently over 60% , even in patients with metastatic disease.
