General | Latest Info

Metastatic cancers do not become new form of cancer. For example, lung cancer that spreads to the liver is called metastatic Lung Cancer rather than liver Cancer. This type of metastatic cancer is common in advanced stages of Lung Cancer. It can be challenging to treat and often has poor prognosis. In this article, we look at how Lung Cancer spreads to different organs, its effects on the body, and how doctors treat it. How quickly cancers spread depends on a multitude of factors such as individual health status, type of Lung Cancer, and response to treatment. For example, type called large cell carcinoma, which accounts for about 10-15 % of Lung cancers, tends to grow and spread quickly, which makes it harder to treat. Comparing the likelihood of Lung Cancer spreading quicker than other cancers requires more specialized studies. Christina Chun, MPH Answers represent the opinions of our medical experts.

Metastatic vs. second primary cancer

Measurements and Main Results: Forty-four patients meet criteria for having metachronous second primary Lung Cancer. There were no statistically significant differences between case subjects and control subjects in prognostic variables. Median Survival time and 2-year Overall Survival rate for metachronous second primary group, compared with control subjects, were as follow: 11. 8 versus 18. 4 months and 31. 0 versus 40. 9 %. The survival difference was largest in those with stage I metachronous second primaries. Second primary Lung Cancer refers to new primary Lung Cancer that develops after curative intent therapy for first primary Lung Cancer, or when two Lung cancers with different histologies are found at time of diagnosis. It is estimated that between 4 and 10 % of all patients with non-small cell Lung Cancer subsequently have MSPLC. The Decisions to perform surveillance or screening imaging for MSPLC after curative-intent treatment is challenging. Clinical decisions must take into account the benefit-risk balance of routine imaging of this select cohort of patients. In National Lung Screening Trial, patients with previous history of Lung Cancer were excluded from enrollment despite being at high risk of developing MSPLC. It is unlikely that randomized control Trial will be designed to investigate the benefit of Lung Cancer Screening specifically in this group of patients. Observational studies investigating prognosis in this select group will give insights into potential risks and benefits, from which further research can be inform. To benefit from Screening, one must be able to tolerate curative-intent treatment of screen-detect early-stage Lung Cancer. Treatment of first primary Lung Cancer may impair one's ability to tolerate treatment of MSPLC. To analyze the benefit-risk balance of Screening, we must understand the potential difference in outcome that can be expected when detecting MSPLCs. The 5-year survival rate for all patients who present with SPLC is about 30 %, and is about 40 % for those who undergo surgical resection, lower than the approximately 70 % rate for all patients with NSCLC who undergo curative-intent Lung resection. To the best of our knowledge, no previous studies have included control subjects to investigate prognosis in patients with MSPLCs. In this study, we investigated Survival in patients with MSPLCs compared with matched patients presented with first primary Lung Cancer. We hypothesize that patients with MSPLCs have poorer survival compared with those with FPLC, even when matched for prognostic factors associated with mortality.

Treatment options For Non-Small Cell Lung Cancer are Base mainly on the stage of cancer, but other factors, such as persons overall health and lung function, as well as certain traits of cancer itself, are also important. If you smoke, one of most important things you can do to be ready for treatment is to try to quit. Studies have shown that patients WHO stop smoking after diagnosis of Lung Cancer tend to have better outcomes than those WHO do Treating occult Cancer For these cancers, malignant cells are seen on sputum cytology but no obvious tumor can BE found with bronchoscopy or imaging tests. They are usually early-Stage cancers. Bronchoscopy and possibly other tests are usually repeated every few months to look for tumor. If a tumor is find, treatment will depend on stage. Treating Stage 0 NSCLC Because Stage 0 NSCLC is limited to lining layer of airways and has not invade deeper into lung tissue or other areas, it is usually curable by surgery alone. No chemotherapy or radiation therapy is needed. If you are healthy enough for surgery, you can usually BE treated by segmentectomy or wedge resection. Cancers in some locations may be treated with sleeve resection, but in some cases they may be hard to remove completely without removing the lobe or even the entire lung. For some Stage 0 cancers, treatments such as photodynamic therapy, laser therapy, or brachytherapy may BE alternatives to surgery. If your cancer is truly Stage 0, these treatments should cure you. Treating Stage I NSCLC If you have Stage I NSCLC, surgery may BE the only treatment you need. This may be done either by taking out lobe of lung that has a tumor or by taking out smaller piece of lung. AT least some lymph nodes in the lungs and in space between lungs will also be removed and check for Cancer. Segmentectomy or wedge resection is generally an option only for very Small Stage I cancers and for patients with other health problems that make removing an entire lobe dangerous. Still, most surgeons believe it is better to do lobectomy if the patient can tolerate it, as it offers the best chance of cure. For people with Stage I NSCLC that has higher risk of coming back, adjuvant chemotherapy after surgery may lower the risk that cancer will return. But doctors are always sure how to determine which people are likely to BE helped by chemo. New lab tests that look AT patterns of certain genes in cancer cells may help with this. Studies are now being done to see if these tests are accurate. After surgery, removed tissue is checked to see if there are cancer cells on the edges of the surgery specimen.

A Word From Verywell

Stage 4 Lung Cancer remains a serious diagnosis, but it is important to remember that it is not the same disease it was just 20 years ago. Survival rates are ever-increasing, and newer medications can now personalize treatment in ways that were once unheard of. Try not to let survival statistics overwhelm you. Instead, learn as much as you can about your specific cancer and treatment options available to you. If you have any doubts about treatment recommendations, do not hesitate to seek a second opinion, ideally from a specialist in one of 71 National Cancer Institute-designate treatment centers in the United States. Their practitioners are more likely to be on top of current research and treatment strategies.


Brain Metastases Symptoms

Lung cancer is the most common cancer that spreads to the brain; as many as 40 % of people diagnosed with lung cancer will develop brain metastases at some point. Both non-small cell lung cancer and small cell lung cancer can be involve. SCLC can spread to the brain rapidly, often before the first cancer diagnosis is even make. Prophylactic cranial irradiation, type of radiation therapy, may be used to attempt to prevent this from occurring. Lung cancer that has spread to the brain can cause symptoms both by destroying brain tissue and by creating inflammation and swelling that places pressure on structures in the brain. Headaches Nausea and vomiting Seizures Loss of balance and coordination Difficulty with speaking Vision changes Weakness on one side of body Fatigue lung cancer metastatic to the brain is usually diagnosed with either CT scan or MRI of the brain. Treatment is primarily palliative, meaning that the goal is to control symptoms and not to try to cure cancer. Steroids may be used to decrease swelling. Pain medications and anti-seizure medications may be used to control headaches and seizures. Radiation therapy may also be very effective in reducing symptoms for some people. Sometimes only one or few brain metastases are presentwhat's call oligometastases. In these instances, treatment with either surgery or stereotactic body radiotherapy, cyber knife or gamma knife, has helped some people gain long-term control over disease.


Diagnosis

Diagnosis of non-small cell lung cancer can be challenging. It's not uncommon for people to be misdiagnosed. For more than 30 % of NSCLC patients, it takes three or more visits to doctor before their symptoms are correctly diagnosed as lung cancer. Chest X-ray often offer the first evidence of lung cancer, though it is not entirely reliable for this purpose. This kind of imaging may be done for unrelated problems or order because of suspicious symptoms. Additional tests that can help determine if cancer is present include: computed tomography, which provides image of chest Sputum cytology, which examines mucus from your lungs under microscope to check for cancer cells. However, lung biopsy is needed to confirm diagnosis and determine what kind of lung cancer is present.


Treatment

Essentially, treatments for brain metastases are not considered possible cures. They aim to reduce pain and increase how long you live with lung cancer that has spread to the brain. However, that doesn't mean that they can't make significant difference. Studies show that people who are treated with appropriate therapy for ALK-positive lung Cancer with brain metastases, for example, have a survival rate of 6. 8 years. That's huge improvement over the estimated 12-month survival rate for lung Cancer that has spread to the brain. Treatment of brain metastases depends on a number of factors, including how much of the brain is involved and your overall health. Which methods are used is usually determined by how best to control symptoms. For instance, steroids such as Decadron are used to control any swelling of the brain. Anticonvulsive medications are sometimes used to control seizures. Before pursuing this treatment, it's important to consider whether seizures are a side effect of another treatment and to determine whether anti-seizure drug might interact with other medications you're taking. Discuss these points with your doctor.


Stages of Small Cell Lung Cancer

Roughly a third of people are diagnosed in earliest stage of small cell lung cancer, know as limited-stage SCLC. These tumors are present in only one lung but may also have spread to lymph nodes on the same side of the chest. SCLC that has spread to supraclavicular lymph nodes or mediastinal lymph nodes may also be considered limited-stage SCLC. Limited-stage SCLC is often treated aggressively with the aim of curing disease. This may involve: Chemotherapy alone, Chemoradiation to chest Surgery followed by Chemotherapy Surgery followed by Chemoradiation SBRT followed by Chemotherapy.


Non-Small Cell Lung Cancer

Stage 4 non-small cell lung cancer is the most advanced stage of lung cancer. Also called metastatic lung cancer, it refers to any size and type of NSCLC that has one of the following: Spread from one lung to other lung Spread to another part of body Spread to fluid around lung or heart stage 4 lung cancer is not curable, but it is treatable. Surgery is rarely used unless a tumor is causing major obstruction in airways or interfering with function of the heart or other vital organs. In addition to chemotherapy, radiation therapy, and immunotherapy, there are newer targeted therapies like Xalkori and Tarceva that are able to identify and attack cancer cells with specific genetic mutations. Together, these treatments can help prolong life and allow you better quality of life. Clinical trials should also be consider, providing you access to experimental treatments when currently available drugs prove intolerable or ineffective.


Prognosis

Staging of lung cancer is used not only to direct treatment but to predict the course and outcome of disease. The key to prognosis is survival rate. This is the percentage of people with disease who are expected to live for a period of time after diagnosis. The survival rate is based on everyone with the disease, irrespective of their age and general health at time of diagnosis. As such, if you are in good health, your likelihood of exceeding estimated survival time will be better than people who are in poor health. Most epidemiologists use five-year survival rates for comparative purposes. These predict a proportion of people who will live for at least five years following diagnosis. The more advanced the cancer stage, lower the survival rate will be. Five-year survival rates for NSCLC and SCLC following treatment are as follow: remember that everyone is different and that every cancer is different. While lung cancer staging is an invaluable tool for ensuring a standardized level of care based on current understanding of disease, that understanding is changing every day. With the rapid introduction of newer immunotherapies and target drugs, you can expect to see survival times increasing for people with NSCLC and SCLC in coming years.


Coping

If you have only recently been told you have lung cancer, you may be very overwhelmed or even frighten. Learning as much as you can about your cancer can help you feel more in control of your treatment and help you play an active role in your care. You may feel isolated as you face something that, perhaps, nobody in your group of loved ones can understand. Participating in cancer support groups and communities may allow you to connect with others who are walking similar road. Be patient with yourself if you are feeling out of sorts. Nobody really knows how they will feel until they are diagnose. Emotions you experience may span the spectrum from sadness to anger to intense anxietysometimes in just a matter of minutes.

One-year net survival by stage

Table

Stage 1Cancer is only located in the lungs.
Stage 2Cancer is located in the lungs and nearby lymph nodes.
Stage 3Cancer is located in the lungs and lymph nodes in the middle of the chest.
Stage 3ACancer is found in lymph nodes, but only on the same side of the chest where cancer first started growing.
Stage 3BCancer has spread to lymph nodes on the opposite side of the chest or to lymph nodes above the collarbone.
Stage 4Cancer has spread to both lungs or to another part of the body.

While this data is useful to a degree, survival rates are statistics and don't necessarily give an accurate estimate of how long a particular individual will survive with disease. There are many factors that affect lung Cancer survival rates, which must be kept in mind. Some of these include: age: younger you are when you're diagnosed with lung cancer, better your chances of enjoying a longer life. Unfortunately, younger people are more likely to be diagnosed with late stage of disease since they may not be seen as at risk for lung Cancer. Sex: Women tend to have better prognosis, or chance of recovering from lung cancer, at each stage of disease. Race: Survival rates appear to be lower for African Americans than they are for white or Asian people. Other medical conditions: People who have other serious medical conditions such as heart disease, diabetes, or other lung diseases have a lower survival rate than those without pre-existing health concerns. Complications of lung Cancer: There are many possible complications of lung cancer, some of which can decrease survival rate. Response to treatment: Chemotherapy and other treatments often have side effects that are temporary, but in some cases, medication or radiation can cause dangerous health problems. Lung damage, heart damage, hypertension, and coronary artery disease may result from cancer treatment and could lead to deterioration of overall health, which would impact survival rates. Smoking: continue smoking after diagnosis of lung Cancer can reduce survival rate. Quitting smoking, on the other hand, has been shown to increase the chance of surviving early-Stage non-small cell lung Cancer and, possibly, small cell lung Cancer as well. In a study that followed lung Cancer patients, those who quit smoking within three months of their diagnosis had a survival rate of almost 62 %; for those who kept smoking, survival rate was just 41 % year after diagnosis. Treatment center: Researchers have found that survival rates for people with Stage 4 lung Cancer were higher for those treated at academic Cancer center than at community cancer center, particularly for those who have lung adenocarcinoma.


Survival rates

There are three main types of NSLC that vary by their incidence, aggressiveness, and parts of the lung they invade: lung adenocarcinoma, most common type accounting for 40 % of diagnoses that develop in the outer edges of the lung. Squamous cell lung carcinoma, second most common type accounting for 25 % to 30 % of cases that mainly affect airways of lungs Large cell lung carcinoma, rare type of NSCLC that can develop in any part of lung and tend to be very aggressive Research publish in Cancer Management Research conclude that survival rates vary by Cancer type, with lung adenocarcinoma being most favorable overall. By contrast, people with SCLC have a five-year survival rate of just 5.

Results

Seven cohort studies and 15 randomized control trials were included in the meta-analysis. All studies assess mortality without treatment in patients with non-small cell lung cancer. Pool proportion of mortality without treatment in cohort studies was 0. 97 and 0. 96 in randomized controlled trials over median study periods of eight and three years, respectively. When data from cohort and randomized control trials were combine, pooled proportion of mortality was 0. 97. The Test of interaction showed statistically non-significant difference between subgroups of cohort and randomized controlled trials. Pool mean survival for patients without anticancer treatment in cohort studies was 11. 94 months and 5. 03 months in RCTs. For combined data, pool mean survival was 7. 15 months, with statistically significant difference between the two designs. Overall, studies were of moderate methodological quality.


Cancer and the Lung

Primary Lung Cancer is very heterogeneous in its Clinical presentation, histopathology, and Treatment response. Conventionally, Lung Cancer has been divided into NSCLC and SCLC. For both groups, cancer stage is the most significant predictor of survival, 1 2 as illustrated in Figure 1. Five-year survival rates were comparable between two large Clinical patient data resources that were from different institutions At different time frames: one from MD Anderson Cancer Center and one from Mayo Clinic, indicating little improvement in NSCLC survival in the last 30 years. In SCLC, five-year survival rate ranges from approximately 25 % for limited disease to 1 %-5 % for extensive disease. 2-4 Treatment modality, mostly dictated by Lung Cancer stage and patients ' performance status, directly determines disease survival. For NSCLC, surgical resection is standard treatment for stage I-II disease; patients with IB or II disease are now being offered adjuvant chemotherapy. 5 Some patients with stage IIIA tumors are operable but often receive pre-or post-operative radiation and / or chemotherapy. For locally advanced, inoperable stage IIIA tumors, radiation with chemotherapy remains standard of care; for select patients with IIIB or IV disease, chemotherapy remains standard Treatment in conjunction with supportive care. In SCLC, majority of patients with limited disease are treated with single-agent or combination chemotherapy with radiation Therapy, and prophylactic cranial irradiation is commonly used In both NSCLC and SCLC, systemic dissemination can occur as solitary metastasis, oligometastasis, and multiple metastases. Solitary metastasis constitutes the majority of long-term survivors in advanced-stage Lung Cancer. 6 At present, for any given chemo-or radiotherapy regimen, which is prescribed by standard protocol with fixed dosage, response rate and toxicity range varies widely among patients. Disease-free survival time, even after adjusting for well-establish predictors, ie, disease stage, histology, performance status, and treatment, varies significantly. Obviously need are easily-measurable biologic markers to stratify patients prior to Treatment for optimal results in survival and QOL and to monitor Treatment responses and toxicities.

Materials & methods

Significant correlations between radiomic features and survival were observed for four clinical groups: large cell carcinoma,. Significant LoG-rank relationships between features and survival time were observed for three clinical groups:, and. Automatic survival prediction performance is superior for combined radiomic features with age-TNM in comparison to standard TNM clinical staging information clinical Group, mean area-under-ROC-curve:, and. All 315 NSCLC patients were Group based on histology and TNM Classification. Among them, 277 patients were grouped into four histology classes with a median age of LCC = 65. 20, SCC = 70. 79, ADC = 64. 58 and NOS = 65. 79; 312 patients were Group in four tumor size with median age of T1 = 68. 43, T2 = 69. 78, T3 = 63. 88 and T4 = 64. 61; 315 patients were grouped into five lymph nodes types with a median age of N0 = 70. 47, N1 = 71. 78, N2 = 65. 02, N3 = 62. 86 and N4 = 73. 28; 315 patients were grouped into four distant metastases, primarily M0 with median age of M0 = 67. 27; 314 patients were grouped into four TNM Group with a median age of I = 71. 94, II = 74. 73, IIIA = 66. 91, IIIB = 64. 18. Figure Figure1 1 shows the Spearman rank correlation between radiomic features and survival time of patients, for groups defined using NSCLC subtype and TNM variables. With respect to patient groups defined based on NSCLC subtypes, we observe highest absolute correlation values for patients with large cell carcinoma and not other specified subtypes. In particular, five features appear to be moderately correlate with survival time of LCC patients, with absolute correlation values between 0. 35 and 0. 43. These results are statistically significant with corrected P < 0. 05. Correlation values for NOS patients are not statistically significant following Holm-Bonferroni correction, although this could be due to the smaller number of patients in that group. Note that SCC Group shows no significance, while having a size similar to LCC. In the case of groups related to tumor size, we also find eight radiomic features moderately correlate with survival for patients with T2 tumors, with absolute correlation values between 0. 31 and 0. 37. Features derive from T1, T3 and T4 tumors exhibit lower correlation values that are not significant following Holm-Bonferroni correction. For patient groups derived from lymph node variables, six features are moderately correlate to survival time for patients without lymph node involvement, with absolute correlation values around 0. 30. Features derived from N1 patients also show mild correlations. However, these are not significant following Holm-Bonferroni correction, possibly due to the small size of this group. In contrast, N2 and N3 groups have comparably weaker correlation values than N0, none of these values being statistically significant. Unlike for N1, group size is not such an important factor in these results of non-significance.

Results

The Chart below reflects CTCA and SEER survival rates for small cell Lung Cancer patients with distant disease who were diagnosed between 2000 and 2015. It includes estimates of the percentage of small cell Lung Cancer patients with distant disease who survive for six months to five years after initial diagnosis, as recorded in CTCA and SEER databases. This analysis includes small cell Lung Cancer patients from CTCA who had Primary tumor sites as cod by ICD-O2 from C340 to C343 or from C348 to C349, were diagnosed from 2000 to 2015 and received at least part of their initial course of Treatment At CTCA. All patients included in the analysis were considered analytic patients by CTCA. Small cell Lung Cancer patients with distant disease from SEER database and small cell Lung Cancer patients with distant disease from CTCA database were included in the analysis. In addition, analysis excludes patients whose medical records were missing any of the following information: SEER Summary Stages Primary tumor sit Cancer histologic types Date of initial diagnosis Age At initial diagnosis Gender Race CTCA sample is relatively small because only metastatic small cell Lung Cancer patients who had been initially diagnose At CTCA and / or receive At least part of their initial course of Treatment At CTCA were include. These factors significantly reduce the size of the CTCA sample, which means that estimates reflected in the survival chart may be subject to high variation and may not be replicated in future when we have larger CTCA sample for analysis. 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, delivery of care, nor the meaning of CTCA and SEER analysis. Not all cancer patients who are treated at CTCA hospital may experience these same results.

Discussion

Improvements in lung Cancer diagnosis and Treatment have increased the 5-year survival rate and median survival time of patients with stage IV NSCLC. In recent years, increased understanding of genetic changes involved in lung cancer has led to molecular targeted therapy. Additionally, surgical techniques are also rapidly evolving. The emergence of radiofrequency ablation and endoscopy has contributed to improving the safety of surgical procedures. Individualize Treatment plans may reduce the occurrence of Adverse Events and improve the quality of life of patients. The current study involves retrospective analysis of a large population of patients with stage IV NSCLC selected from the SEER program. Compared with patients with other organ metastases, patients with lung metastasis had the longest OS, and patients with single organ metastasis had increased OS compared with patients with multiple organ metastases. This suggests that the type and number of metastatic organs may affect prognosis of patients with stage IV NSCLC. This is similar to previously published studies investigating bladder and colorectal Cancer. Furthermore, current study establish that surgical resection of primary and metastatic organs may significantly improve prognosis of patients with stage IV NSCLC. The current study demonstrates that patients with only lung metastases had the best prognosis, patients with only brain metastases had slightly improved prognosis compared with patients with only bone metastases, while those with liver metastases had the worst prognosis. Patients with only one metastasis had improved prognosis compared with patients with multiple metastases. Previous studies have revealed similar results; patients with NSCLC and SCLC with liver metastasis and multiple metastases have the worst prognosis. Similar results were obtained using the AJCC Staging system, where the number of metastatic organs had an effect on prognosis of patients. Notably, effect of the number of metastases is not the same for different types of Cancer, OS of patients with pancreatic Cancer is not affected by either single or multiple organ metastases. Pancreatic Cancer is characterized by rapid growth, abundant pancreatic blood and lymphatic vessels, and incomplete pancreatic capsule. Therefore, time of distant metastasis is relatively early, so whether there is distant metastasis or not, has little impact on OS. Multivariate Cox regression analysis revealed that the prognosis of patients who underwent surgery for primary and metastatic lesions was better compared with patients who did not undergo the above. Surgical Treatment remains the main approach used for treatment of the majority of malignant Tumors. Previously published studies reveal that certain patients with advanced NSCLC with unilateral contralateral lung metastasis, single brain, bone or adrenal metastasis may be treated surgically. For patients with NSCLC with isolated metastases and resectable pulmonary lesions, resection of metastatic organs may also be consider. However, how isolated liver metastases should be removed remains unclear. Previous studies demonstrate that surgery serves an important role in treatment of liver metastasis of neuroendocrine carcinoma and colorectal Cancer, but not in lung Cancer.


1. Introduction

Recent insights into the biology of non-small cell lung cancer have lead to a wealth of novel therapies, including target agents and immune checkpoint inhibitors with significant clinical activity. So far, there is limited data on the efficacy of these drugs in patients with brain metastases, but intracranial responses have been documented in emerging studies. At the meeting, multidisciplinary group of experts discussed biology of BMs as well as anatomy of blood-brain barrier. The group considered treatment options for NSCLC and their effect on BMs, focusing on target treatment and combination treatment for epidermal growth factor receptor mutate NSCLC and those with anaplastic lymphoma kinase rearrangement.

18F-FDG PET scanning

Decision analyses demonstrate that 18F-FDG PET scanning may reduce overall costs of medical care by identifying patients with falsely negative CT scans in mediastinum or otherwise undetected sites of metastases. Studies conclude that money saved by forgoing mediastinoscopy in 18F-FDG PET-positive mediastinal lesions was not justified because of the unacceptably high number of false-positive results. A randomized study found that addition of 18F-FDG PET scanning to conventional staging was associated with significantly fewer thoracotomies. The second randomized trial evaluating the impact of 18F-FDG PET scanning on clinical management found that 18F-FDG PET scanning provides additional information regarding appropriate stage but does not lead to significantly fewer thoracotomies.

Standard Treatment Options for Stage 0 NSCLC

With improvement in radiation therapy-delivery technology in the 1990s, including tumor-motion management and image guidance, phase I / II trials demonstrate feasibility of dose-escalation radiation therapy to 74 Gy with concurrent chemotherapy. However, phase III trial of conventional dose of 60 Gy versus dose escalation to 74 Gy with concurrent weekly carboplatin / paclitaxel do not demonstrate improved local control or progression-free survival, and OS was worse with dose escalation. There was a nonsignificant increase in grade 5 events with dose escalation and higher incidence of grade 3 esophagitis.


Surgery

Surgery is the treatment of choice for patients with stage II NSCLC. Lobectomy, pneumonectomy, or segmental resection, wedge resection, or sleeve resection may be performed as appropriate. Careful preoperative assessment of patients ' overall medical condition, especially patients ' pulmonary reserve, is critical in considering benefits of surgery. Despite immediate and age-related postoperative mortality rate, 5 % to 8 % mortality rate with pneumonectomy or 3 % to 5 % mortality rate with lobectomy can be expect. Current evidence suggests that lung cancer resection combined with CMLND is not associated with improvement in survival compared with lung cancer resection combined with systematic sampling of mediastinal lymph nodes in patients with stage I, II, or IIIA NSCLC. Conclusions about the efficacy of surgery for patients with local and locoregional NSCLC are limited by the small number of participants studied to date and potential methodological weaknesses of trials.
