Dünyada sık görülen kanserlerin sıklığı ve mortaliteleri Erkek Kadın Akciğer Meme Kolon/rektum Mide Karaciğer Prostat Serviks Özofagus Mesane Non-Hodgkin lenfoma Based on the most recent incidence and mortality data available, Parkin and colleagues estimated that in the year 2000 there would be over 10 million new cases, 6.2 million deaths and 22.4 million people living with cancer.1 This estimate represents an increase of around 23% in incidence and mortality since the estimates for 1990. Lung cancer is the most common cancer in the world1 with the highest mortality.2 Areas with the highest incidence are Europe, North America, Australia/New Zealand and South America. The rates in China, Japan and South-East Asia are moderately high. In developing countries, the highest rates in men are seen in areas where the habit of smoking has been longest established: the Middle East, China, the Caribbean, South Africa, Zimbabwe and the Pacific.1 In the USA, the 1-year relative survival rates for lung cancer have increased from 34% in 1975 to 41% in 1997, largely as a result of improvements in surgical techniques.3 However, the 5-year relative survival rate for all stages combined is only 15%. The survival rate is 48% for cases detected when the disease is localised, but only 15% of lung cancers are detected at this early stage.2 References Parkin DM, et al.

However, with increasing evidence that cigarettes cause lung cancer, cigarette consumption has declined in the USA. In the developing world, cigarette use is still increasing, at a rate of ~3.4% per year.1,2 During 1990-1997, US mortality from lung cancer declined significantly among men (-1.7% per year), in contrast to rates for women, which continued to increase but at a much slower pace. The increase in incidence rate among women reached a plateau in the 1990s, with incidence in 1998 being 43.4 per 100,000.4 Decreasing lung cancer incidence and mortality rates most likely result from decreased smoking rates over the previous 30 years, with decreasing smoking patterns among women lagging behind those of men.4 Estimated figures for the year 2000 indicate that 86% of lung cancer cases in men and 49% in women were due to smoking, although there was considerable regional variation in these figures.5 According to the World Health Organization, tobacco-related deaths are expected to increase from ~4 million per year in 1998 to ~10 million per year by the 2030s, with 70% of those deaths occurring in developing nations.1 This is a higher death toll than is expected from maternal and major childhood conditions, malaria and tuberculosis combined.1 References World Health Organization.

Symptoms of advanced lung cancer can be more distressing than with other types of malignancy and are particularly associated with the site of the disease. In a recent study of 673 patients with NSCLC, the major presenting lung cancer symptoms at diagnosis were dyspnoea (87% of patients), cough (86%), pain (81%), loss of appetite (75%), and haemoptysis (41%).1 Although 81% of these patients had three or more of these symptoms, there were some patients who presented with only one symptom (5% of patients) or no symptoms (2%).1 Although not assessed in this study, weight loss is also a major symptom of NSCLC.

Akciğer Kanseri Tipleri 1) Küçük hücreli dışı Yassı hücreli kanser Adenokanser Büyük hücreli kanser 2) Küçük hücreli akciğer kanseri

Yassı hücreli kanser(~30%) Akciğer Kanseri (Küçük hücreli dışı) Yassı hücreli kanser(~30%) Erkeklerde sık Sigarayla ilişkili (doz-bağımlı) Sıklıkla lokal olarak yayılır Balgamda malign hücre bulunabilir Yüksek düzeyde gen ekspresyonu vardır ( detoksifikasyon/antioksidan) Adenokarsinoma (30-50%) Kadınlar ve sigara içmeyenlerde daha sıktır, Lezyonlar genellikle periferaldir, Sıklığı artmaktadır K-ras mutasyonu sıktır Bronkoalveoler karsinom alt grubu vardır. About 80% of all lung cancer cases are NSCLC. The major cause of NSCLC is tobacco smoking (85% correlation) and it affects a large number of people in their productive middle years. The incidence of NSCLC is increasing as a result of ageing populations and increasing numbers of female smokers. However, tobacco smoking is by no means the only cause of lung cancer: environmental, dietary and genetic factors have all been identified as increasing the risk of the disease. There are three major types of NSCLC. Each type has a different incidence and pattern of occurrence by age, sex, race and geographical area.1 The histological type of NSCLC may affect treatment outcome. Squamous-cell carcinoma: consists of layers of epithelial cells that secrete keratin, and therefore often present as obstructing tumours in the bronchi most commonly found in men represents 30% of all cases closely correlated with smoking has a molecular profile including high expression of genes involved in cellular detoxification and antioxidation.2 Adenocarcinoma: most common type of lung cancer in women and non-smokers and the worldwide incidence is increasing characterised by high-level expression of small-airway-associated or imunologically related proteins2 and k-ras mutations are frequently reported3 a subtype of adenocarcinoma called bronchoalveolar carcinoma, which often presents at an earlier stage than other adenocarcinomas, can be less aggressive, and has been associated with better survival in some studies. Early diagnosis and surgical treatment are therefore particularly valuable in nodular bronchoalveolar carcinoma4 in contrast with other bronchial carcinomas, survival of patients with bronchoalveolar carcinoma is influenced more by the extent of lung involvement (eg presence of bilateral lesions or production of mucin by tumour cells) than by the extent of lymph node metastases5 metastatic bronchoalveolar carcinoma can be an aggressive disease, with a prognosis similar to that seen for adenocarcinoma.6 Adenocarcinoma and large-cell carcinoma: were found to recur after surgery more frequently than squamous-cell carcinomas in one study (0.088 and 0.042 recurrences per patient per year, respectively), even though all cancers were the same stage (T1 N0).7 References Wingo PA, et al.

Small-cell lung cancer (SCLC) accounts for approximately 20% of all lung cancer cases.1 Cellular classification small-cell carcinoma mixed small-cell/large-cell carcinoma combined small-cell carcinoma (SCLC combined with neoplastic squamous and/or glandular components). Without treatment, SCLC has the most aggressive clinical course of any type of pulmonary tumour (median survival from diagnosis of 2-4 months), but is much more responsive to chemotherapy and radiotherapy than other tumour types.2 Owing to the tendency to disseminate early, SCLC is treated as a systemic disease, with chemotherapy as the cornerstone of treatment. Despite being initially chemosensitive, these carcinomas acquire drug resistance during the course of the disease. References Zöchbauer-Müller S, et al. Ann Oncol 1999; 10 (Suppl 6): 83-91.

During the initial evaluation, all patients should have their history taken and undergo physical examination, chest X-ray and chest computed tomography (CT) scans (including the adrenal glands), liver CT scan or abdominal ultrasound. Other evaluations include a complete blood count, liver function tests, measurements of electrolytes, calcium, blood urea nitrogen, and creatinine, as well as a baseline ECG. Bone scans and/or brain CT scans may be appropriate in some patients.1 The extent of the tumour, the involvement of the lymph nodes, and chest wall or mediastinal invasion can be determined with similar efficacy using either CT or magnetic resonance imaging (MRI). CT is used more commonly, although MRI may be preferable in specific situations, for example in evaluating superior sulcus tumours.2 Positron emission tomography (PET) with radiolabeled fluoro-2-deoxyglucose combined with CT was significantly more accurate than CT alone in identifying lymph node involvement in NSCLC.3 References NCCN Guidelines 2000.

Additional stages are outlined below. Tumour stages: TIS: carcinoma in situ (confined to airway lining) T1-T4: ranging from tumour <3 cm in greatest dimension through to tumour of any size that invades the mediastinum, heart, great vessels, trachea, oesophagus, vertebral body or carina. Lymph node stages: N1: metastasis to ipsilateral peribronchial and/or ipsilateral hilar lymph nodes and intrapulmonary nodes involved by direct extension of primary tumour N2: metastasis to ipsilateral mediastinal and/or subcarinal lymph node(s) N3: metastasis to contralateral mediastinal, contralateral hilar, ipsilateral or contralateral scalene, or supraclavicular lymph node(s). Distant metastasis stages: M1: distant metastasis present. The schematic diagram shows examples of some tumour stages: Early stage 0 (carcinoma in situ): tumour is confined to the airway lining stage IA (T1 N0 M0): tumour has spread to nearby lung tissue but has not reached the main bronchus Localised stage IIB (T2 N1 M0/T3 N0 M0): tumour has reached main bronchus and local lymph nodes or direct local invasion into chest wall, diaphragm, mediastinal pleura or parietal pericardium Advanced stage IIIB (T4 Any N M0/Any T N3 M0): tumour has invaded chest wall, trachea and the contralateral lymph nodes stage IV (Any T Any N M1): distant metastasis present in the brain.

Investigations of adjuvant chemotherapy or radiotherapy following surgery are currently underway chemoprevention trials for second cancers in patients resected for stage I NSCLC are also underway. Stage II:1 many patients resected for stage II NSCLC may later develop regional or distant metastases. Investigations of adjuvant chemotherapy or radiotherapy following surgery are currently underway. Stage IIIA:1 surgery alone in highly selected cases chemotherapy combined with radiotherapy, chemotherapy plus radiotherapy followed by surgery, or chemotherapy after surgery (encouraging results for patients with good performance status). Optimal sequencing and scheduling have yet to be determined. Neoadjuvant chemotherapy could be considered for patients with good performance status surgery and post-operative radiotherapy (can improve local control, but there is controversy over whether it improves survival) radiotherapy (long-term survival benefit in 5-10% of patients; patients with high performance status are most likely to benefit). Stage IIIB:1 radiotherapy alone (patients with advanced disease and high performance status are most likely to benefit) chemotherapy combined with radiotherapy (modest survival benefits compared with radiotherapy alone) chemotherapy and/or radiotherapy followed by surgery chemotherapy alone (for patients with malignant pleural effusion). Stage IV:1 cisplatin-containing combination regimens produce higher response rates than single-agent chemotherapy current treatments produce modest survival benefits compared with supportive care alone, and there is no standard regimen new chemotherapy agents are being evaluated in clinical trials external radiotherapy may be used for palliation of symptoms such as compression of the trachea, oesophagus or bronchus; bone or brain metastases; local pain; vocal cord paralysis; haemoptysis; or superior vena cava syndrome endobronchial laser therapy or brachytherapy may be useful in treating lesions obstructing the proximal airways. Many patients do not receive any treatment, even first line; the proportion of patients receiving treatment reduces with the stage of the disease. Reference 1. PDQ Treatment Guidelines 2000.

In addition, platinum-containing chemoradiotherapy results in superior survival compared with radiotherapy alone in stage III disease. Le Chevalier and colleagues found that patients treated with vinorelbine alone had a poorer survival than those treated with vinorelbine plus cisplatin.1 Recent randomised trials have demonstrated the benefit of combining cisplatin with new active agents in NSCLC, resulting in increased tumour response and prolonged median survival compared with cisplatin treatment alone,1-9 recently reviewed by Gandara et al.10 The slide outlines recent randomised trials that have compared the activity of some of the new combination regimens with older regimens such as etoposide/cisplatin. Although the trials demonstrated significant advantages for the new combinations, the significantly higher response rates do not appear to translate into equivalent improvements in survival.10 Combination therapy with three or more drugs, with new chemotherapy agents plus radiotherapy, or with newer agents in the absence of platin therapy, is also being tested in ongoing trials.11-13 References Le Chevalier T, et al.

Evre IIIA: Neoadjuvant kemoterapi Cerrahi tedavi evre IIIA küçük hücre dışı akciğer kanserli hastaların tedavisinde başarılı değildir. Üç randomize çalışmada neoadjuvant cisplatin-bazlı kemoterapi sağkalımda başarılı sonuçlar sağlamıştır. Faz III gemcitabine/cisplatin çalışmasında hastaların %70%’den ve lenf nodüllerinin %53’den fazlasında gerileme olmuştur.(van Zandwijk 2000) Neoadjuvant docetaxel faz III çalışmalarda uzun bir sağkalım sağlamıştır. (Mattson 2001) Surgical resection alone fails to cure the majority of patients with NSCLC, due to undetected metastases at the time of surgery. Although post-operative chest radiotherapy virtually eliminates locoregional recurrences, no improvement is observed in survival. Therefore neoadjuvant chemotherapeutic approaches are warranted. At least three randomised trials have been conducted to evaluate neoadjuvant cisplatin-based chemotherapy.1 For two of these studies, statistically significant improvements in survival results were observed in those patients receiving neoadjuvant chemotherapy, compared with those receiving surgery alone. Randomised trials are in progress to determine whether triple modality regimens are superior to two modalities. In an additional trial, 47 patients with stage IIIA disease had a response rate of >70% following induction therapy with gemcitabine/cisplatin.2 Downstaging of the mediastinal lymph nodes occurred in 53% of patients. Based on proven activity and survival benefit in advanced NSCLC, docetaxel has been introduced into neoadjuvant therapy and has been evaluated in a large Phase III randomised trial.3 A total of 274 patients with stage IIIA and IIIB disease were involved. Overall 1-year survival was 59% compared with 51% in the control group. References Bunn PA, et al. Chest 2000; 117: 119S-122S. van Zandwijk N. Anticancer Drugs 2000; 11 (Suppl 1): S17-22. Mattson K.

Küçük Hücreli Akciğer Kanseri Evreleme Extensive Tek bir hemitoraksın dışına çıkan, sınırlı hastalık ötesinde Uzak metastasis Limited Tek bir hemitoraksa ve/veya mediasten ve supraklavikuler nodüllere sınırlı Metastatic (extensive-stage) disease is present at diagnosis in most patients with SCLC. Thus, survival is usually not affected by small changes in the amount of locoregional tumour involvement, as it is for NSCLC. Thus, although relevant, the detailed TNM staging previously described (which is more appropriate when surgery is being considered), is not commonly employed for staging SCLC. Instead, a simplified staging system of ‘limited’ versus ‘extensive’ disease is used.1 Approximately one-third of patients with SCLC present with limited-stage disease.2 In limited-stage disease the tumour is confined to the hemithorax of origin, the mediastinum and the supraclavicular nodes, which can be encompassed within a ‘tolerable radiation’ therapy port.3 The extensive stage of SCLC encompasses any tumour too widespread to be included within the definition of limited stage and any patients with distant metastasis.3 Patients with limited disease have a median survival of 3 months without drug therapy, compared with 1.5 months for patients with extensive disease.2 References PDQ Treatment Guidelines 2000.

In this study, administration of thoracic radiotherapy led to a 14% reduction in mortality rate (p=0.001), which corresponded to a 5% increase in the 3-year survival rate.1 A similar result was also demonstrated in another meta-analysis of 11 randomised trials.2 Most of the benefit occurred in patients <55 years. Several randomised trials have investigated the timing of thoracic radiotherapy and, in general, have suggested that early chemoradiation is superior to late chemoradiation, with observed improvements in overall survival.3 This may be due to early control of metastases. Thus, combination chemotherapy plus chest radiotherapy is considered the standard treatment for patients with limited-stage SCLC.4 Optimal timing and sequencing of thoracic radiotherapy with both established and new agents remain to be resolved.

As a result, use of cisplatin/etoposide (PE) became the ad-hoc international standard for limited-stage SCLC. A number of combination chemotherapy regimens are currently used to treat patients with SCLC, including PE, cyclophosphamide/doxorubicin/vincristine (CAV) and cyclophosphamide/doxorubicin/etoposide (CAE).1 PE has been compared with CAV or CAV alternating with PE in 2 randomised trials.2,3 No difference in survival was observed between the treatment arms (8-9 months) for patients with extensive-stage disease. Although nausea and vomiting were considerable with PE, there was less myelosuppression, neurotoxicity and cardiac toxicity than with CAV. Based on these results, PE has become the most commonly used regimen. The combination of carboplatin/etoposide (CE) has shown activity against SCLC, with less toxicity than PE.4 The CE regimen is often used to treat patients with SCLC. The combination chemotherapy regimens commonly used in extensive-stage SCLC all appear to have similar relative effectiveness, with overall response rates of 70-85%, complete response rates of 10-40% and median survivals of 7-11 months.5 There is no compelling evidence that maintenance chemotherapy prolongs survival for patients with SCLC. In fact it may produce more toxicity and thus negatively impact on quality of life.6 References Kelly K. Chest 2000; 117 (4 Suppl 1): 156S-162S. Fukuoka M, et al.

However, neurological abnormalities have been shown to exist in 30-40% of SCLC patients prior to PCI and a recent meta-analysis demonstrated an absolute 5.4% increase in 3-year survival rate in favour of PCI.2 It is now generally accepted that PCI should be administered to patients with limited-stage disease in complete remission after induction chemotherapy.2,3 Questions remain regarding optimal dose, fractionation schemes and timing or irradiation.

The CP arm also showed significantly better survival than the standard arm (p=0.002). As expected, grade 3/4 diarrhoea was more common in the CP arm than in the PE arm (16% versus 0%, respectively; p<0.001). An ECOG trial investigated topotecan versus observation following 4 cycles of PE induction therapy.2 Progression-free survival was significantly better with topotecan compared with observation (3.6 versus 2.3 months, respectively; p<0.001), but no improvement was observed in overall survival or quality of life. In a Phase III trial of a 4-drug regimen containing cisplatin/etoposide plus cyclophosphamide and epidoxorubicin compared with cisplatin/etoposide alone, the 4-drug regimen yielded higher response rates (76% versus 61%, respectively) and better survival rates (1-year survival 40% versus 29%, respectively) in patients with extensive SCLC.3 References Noda K, et al.

A Phase II comparator study has found oral topotecan to be similar in efficacy to intravenous topotecan in patients with relapsed SCLC, sensitive to first-line therapy, to result in less grade 4 neutropenia and have greater convenience of administration.4 References Huisman C, et al.

Median survival post-diagnosis is approximately 8 months for inoperable (stage IIIB/IV) NSCLC, the most frequently diagnosed group. Earlier diagnosis could increase the percentage of patients treated at stage I, where the outcome of treatment is often good. There is a need for new therapeutic approaches that can provide increased efficacy, both in terms of survival and symptom relief, and less toxicity. Current areas of interest are: novel targeted biological targets advances in molecular and cellular biology have allowed specific pathways involved in cancer cell growth to be pinpointed potential to produce therapies that improve efficacy with minimal adverse effects and less severe impact on quality of life. immunotherapy immunomodulators (eg interferons and interleukins) to increase the activity of the immune system passive immunisation active immunisation. gene therapy still in its infancy possible targets include oncogenes known to be associated with lung cancer (eg K-ras) or genes for powerful immunomodulators (eg interleukins). Prevention would reduce the overall burden of disease (most lung cancer is caused by environmental factors that could be avoided).

Risk factors include: obstructive lung disease. This increases the risk of lung cancer approximately four-fold1 genetic factors. There was a 30% increased risk of cancer in non-smoking women whose parents or siblings had a history of respiratory tract cancer.1 Sputum cytology screening can identify premalignant dysplasia in people with chronic obstructive lung disease and a history of cigarette smoking.1 The sensitivity of sputum cytology as a population-screening tool for the detection of early lung cancer may be improved by several approaches currently under development, including immunostaining to detect hnRNP A2/B1 protein as a biomarker, detection of microsatellite alterations in histological or cytological specimens and detection of p16 hypermethylation indicating inactivation.2 Additional susceptibility factors include defects in DNA repair, polymorphisms in the cytochrome P450 enzymes and the metabolising capability of glutathione S-transferase or acetylation.3 In addition to analysis of sputum samples, molecular tumour markers such as ras and p53 can be identified in tumour tissue, bronchoalveloar lavage fluids and blood components.1,2 Techniques include analysis of gene mutations, allelotyping, gene expression at RNA and protein level, molecular cytogenetics, comparative genomic hybridisation and morphometric studies. Low-dose spiral CT scanning is relatively new, and allows data to be continuously acquired, resulting in a shorter scanning time, lower radiation exposure and improved diagnostic accuracy compared with older methods.2 A review of studies using the laser-induced fluorescence endoscope (LIFE) bronchoscopy device showed improved detection rates, but further evaluation of the effect on lung cancer mortality and the health economic implications associated with this technique require further investigation.2 References 1.

Lazer floresan endoskop bronkoskopi White-light bronchoscopy (WLB) is the most commonly used tool in the diagnosis of lung cancer. However, this technique is limited in its ability to detect premalignant lesions, as they are only a few cells thick and are rarely observed as visual abnormalities. To address this limitation, fluorescence bronchoscopy and the LIFE bronchoscopy system were developed. This system uses a helium cadmium blue laser to stimulate the lining of the bronchi in the lungs to autofluoresce. Two image-intensified cameras amplify the red and green fluorescence intensity differences between normal and abnormal tissues. As the green autofluorescence is much stronger than the red, normal tissue appears green. In dysplasia or cancer, there is a progressive decrease in green, while the red remains unchanged, thus the lesion appears brown, purplish or red. LIFE bronchoscopy allows surgeons to identify subtle changes that are difficult to visualise through conventional WLB. In this case study, a male ex-smoker presented with a persistent cough, and sputum cytology showed cells suggestive of squamous carcinoma.1 The pulmonologist was unable to localise the source of malignant cells. A second examination was carried out. In the right lower lobe it was noted, through WLB, that some thickening had occurred in bronchus RB8, but a similar thickening was also noted elsewhere. Such changes cannot readily be distinguished from inflammation or benign metaplasia. Re-examination using the LIFE system showed an area of abnormal brownish-red fluorescence in the sub-carina. This area was 2-3 mm in width and was confirmed by biopsy as carcinoma in situ, with small foci of microinvasion.

For example, the median survival was 10 or 17 months in those with or without p53 antibodies (p=0.014).2 Several other members of the p53-p21 pathway and the pRb pathway have been found to be altered in lung tumours.3 Decreased expression of tissue inhibitors of matrix metalloproteinases (TIMP-1) has been correlated with response in patients with SCLC (p=0.043).4 Increased expression of matrix metalloproteinases (MMP-3, MMP-11, and MMP-14) was also an independent negative prognostic factor for survival.4 Chromogranin A, a protein present in neuroendocrine vesicles, has also been shown to be an important prognostic factor for survival after performance status and disease stage.5 In addition, expression of topoisomerase II and  (implicated in resistance to doxorubicin and etoposide) has been shown to be predictive of poorer survival and lower response rates, respectively.6 A consistent association has been shown where lung cancer risk is decreased by a G to A polymorphism in the myeloperoxidase (MPO) gene, which is expressed in neutrophils recruited to the lung after chemical or immunological insults.7 The G to A transition results in reduced expression of MPO RNA and several studies have reported a reduction in lung cancer risk for the A/A compared with the G/G genotype. Levels of pleiotrophin in blood samples from patients with SCLC (n=63) and NSCLC (n=22) were compared with levels in 41 healthy people.8 Raised levels of pleiotrophin were found in 87% of SCLC samples and 63% of NSCLC samples, compared with 2.4% of samples from healthy controls. Levels of pleiotrophin appeared to increase as the disease became more advanced. References Gandara DR, et al. Lung Cancer 2001; 34: S75-S80. Zalcman G, et al. Int J Cancer 2000; 89: 81-86.

EGF acts by activating a tyrosine kinase on the intracellular domain of its receptor. This receptor is a target for anticancer therapy.2 Agents are being developed that target specific oncogene activation, such as K-ras inactivation by farnesyl transferase inhibitors.3 Inducers of apoptosis include a bcl-2 antisense oligonucleotide (oblimersen) that has shown in vivo activity against bcl-2 overexpression and disease stabilisation in a Phase I/II study.4 References Bonomi P.

This results in receptor dimerisation, leading to activation of the receptor’s tyrosine kinase and subsequent intracellular signalling. EGFR activation has been implicated in the control of cell proliferation, survival and metastasis.1 There is increasing evidence that EGFR is expressed in a range of human tumours, including NSCLC, and high-level expression has been correlated in many cases with poor prognosis.2,3 Inhibitors of the EGFR in clinical development include the small molecule EGFR tyrosine kinase inhibitors ZD1839 and OSI-774, and the monoclonal antibody C225.4-6 A lack of EGFR positivity has been observed in SCLC.7 References Woodburn J.

Endotelyal proliferasyon ve göç A tumour needs to establish new vasculature to obtain the nutrients necessary to sustain growth beyond 1-2 mm3. Angiogenesis is defined as the development of new capillaries from existing vessels. Tumours induce angiogenesis by increasing production and secretion of angiogenic factors and proteases that act in concert to promote angiogenesis. Secretion of angiogenic factors, such as vascular endothelial growth factor (VEGF) increase endothelial-cell-associated protease activity and stimulate endothelial cell migration and proliferation. Proteases secreted by tumour cells and endothelial cells degrade the extracellular matrix, allowing endothelial cell migration. Together these processes promote angiogenic sprouting and the formation of new tumour vasculature. New vessels formed during pathological angiogenesis, compared with those produced normally, are not well formed and are described as tortuous and leaky. Therapeutic inhibition of tumour angiogenesis should be effective in all solid malignancies and the biological effect should be tumour-specific, as, apart from the female reproductive system, angiogenesis is quiescent in healthy tissues. Furthermore, genetically stable endothelial cells may be less prone to developing drug resistance than tumour cells. Drug delivery is facilitated, because target tissue is in direct contact with blood. Tumour vasculature may be targeted by: preventing new blood vessel growth (angiogenesis inhibition) destroying existing tumour blood vessels (vascular targeting). Angiogenesis inhibition is potentially complementary to other antitumour strategies. Kapiller çoğalması

Korunma Eğitim ve primer korunma Kemoproflaksi Sigarayla mücadele retinoidler EGFR inhibitorleri selenyum COX-2 inhibitorleri Yeşil çay Up to 90% of cases of lung cancer can be attributed to the use of tobacco, and lung cancer incidence and death rates in the USA mirror patterns of cigarette smoking.1 Lung cancer incidence and death could be significantly reduced by: deterring people from beginning smoking helping people to stop smoking protecting non-smokers from environmental tobacco smoke.1 Possible strategies include reducing the availability of tobacco products to adolescents, education, increasing the cost of tobacco products, and use of tobacco tax revenue to fund mass media campaigns to reduce consumption.1 Chemoprevention - defined as the use of specific natural or pharmacological agents to reverse, suppress, or prevent the carcinogenic process and the development of invasive cancer. Development of such agents is made possible by understanding the biology of lung cancer. Retinoids, EGFR inhibitors, selenium, cyclooxygenase-2 (COX-2) inhibitors, green tea and many other possible agents are still under investigation to assess their chemopreventative action, but as yet their role is still unclear.2 The most intensively studied of these agents are the retinoids. However, in trials with lung cancer endpoints, administration of retinoids was either ineffective or, in the case of beta-carotene, led to greater lung cancer incidence and mortality.3,4 Selenium is an essential trace element that reduces certain kinds of tumours in animals and enhances immune properties in humans. Selenium may also reduce the risk of cancer in humans. Metabolites derived from COX and lipoxygenase pathways have important effects on carcinogenesis and growth-related signal transduction, respectively. Inhibition of these pathways may have a role in chemoprevention.5 References Wingo PA, et al. J Natl Cancer Inst 1999; 91: 675-690. Kim ES, et al. Chest Surg Clin N Am 2000; 10: 663-690.
