- Benigna

BENIGN NEOPLASM OF THE LUNG

The benign neoplasms of the lung, representing < 5% of all primary tumors, include :

bronchial adenomas and hamartomas (90% of such lesions) a group of very uncommon benign neoplasms (epithelial tumors such as bronchial papillomas,

fibroepithelial polyps; mesenchymal tumors such as chondromas, fibromas, lipomas, hemangiomas, leiomyomas, pseudolymphomas; tumors of mixed origin such as teratomas; and other diseases such as endometriosis).

BRONCHIAL ADENOMAS Bronchial adenomas (80%are central) are slowgrowing, endobronchial lesions. Adenomas present in patients 15 to 60 years old (average age, 45) Patients may have a chronic cough, recurrent hemoptysis, or obstruction with atelectasis, lobar

collapse, or pneumonitis and abscess formation.

Hamartomas Pulmonary hamartomas have a peak incidence at age 60 and are more frequent in men than in

women. Histologically, they contain normal pulmonary tissue components (smooth muscle and collagen)

in a disorganized fashion.They are usually peripheral, clinically silent, and benign in their behavior

- Maligna

Lung malignancy : cenderung selalu ganasLung malignancy

Klasifikasi

Several histologic variants of each type of lung cancer are described : Adenocarcinoma (males 37%, females 47%) Squamous cell carcinoma (males 32%, females 25%) Small cell carcinoma (males 14%, females 18%) Large cell carcinoma (males 18%, females 10%)

For common clinical use, however, the various histologic types of lung cancer can be clustered into two groups on the basis of likelihood of metastases and response to available therapies:

small cell carcinomas (almost always metastatic, high initial response to chemotherapy) non-small cell carcinomas (less often metastatic, less responsive). Ex : squamous cell carcinoma,

adenocarcinoma, and large cell carcinoma.

The strongest relationship to smoking is with squamous cell and small cell carcinoma.

Small Cell Carcinorma

fast-growing type of lung cancer, small cell carcinoma usually spreads faster than non-small cell lung cancer.

small cell carcinoma accounts for about 15 percent of all lung cancer cases Small cell lung cancer usually starts in or near the lung’s bronchi. The cells can quickly grow into

large tumors that can rapidly spread to the brain, liver, bones, and other parts of the body More common in men than women, small cell carcinoma is almost always caused by smoking and

is rare among those who have never smoked. Heavy exposure to second-hand smoke or to asbestos or radon also can cause small cell carcinoma.

Symptoms include coughing, bloody sputum, shortness of breath, wheezing, chest pain, loss of appetite, and weight loss. The tumor cells cause increased secretion of adrenocorticotropic hormone (a hormone from the adrenal gland), causing Cushing’s disease, which is characterized by a puffy face, weightgain, hump on the lower neck, or elevated blood sugarlevels. Antidiuretic hormone, also secreted by these tumor cells, lead to water retention and low sodium, which can cause confusion. Small cell carcinoma antibodies also can cause weakness by the tumor-producing antibodies against normal tissues (autoanti-bodies).

1. Staging : limited or extensive

Limited small cell carcinoma is confined inside the chest, and extensive small cell carcinoma has spread outside the chest.

2. Because most cases of small cell carcinoma have advanced to the extensive stage, physicians usually recommend combined chemotherapy and radiation therapy to increase the chances of remission. Chemotherapy delivers drugs throughout the body, slows the cancer’s progression, and reduces pain. Radiation therapy uses pinpointed high-energy beams to shrink localized tumors or cancer cells. This treatment is also used to relieve the symptoms of advanced lung cancer or to slow its spread.

3. Surgery is rarely used to treat small cell carcinoma because the disease has usually spread by the time it is diagnosed

Because small cell carcinoma is a very aggressive type of cancer with a high chance of recurring after remission.

LUNG ADENOCARCINOMA (including bronchoalveolar) Adenocarcinoma: A type of cancerous, or malignant, tumor that forms glandular structures. Lung adenocarcinoma is the most common kind of lung cancer, both in smokers and non-smokers

and in people under age 45. This type of non-small cell lung cancer usually develops in the peripheral portion of the lungs. Lung adenocarcinoma cells form recognizable glandular patterns. Slow growing, lung adenocarcinoma can take years to develop from a confined tumor

tometastatic cancer. Symptoms develop slowly as well. They include coughing, shortness of breath, wheezing, chest pain, and bloody sputum

TreatmentIf the cancer is located only in the lungs, surgery is generally recommended. Common lungcancer surgical procedures include thoractomy (opening the chest wall) or median sternoctomy (cutting through the breastbone) during which lung tissue, one lobe, or an entire lung will be removed, depending on the size of the tumor. Another method is video-assisted thoracic surgery (VATS) enables surgeons to remove tissue through smaller incisionsFor aggressive and widespread tumors, physicians recommend chemotherapy and radiation therapy.

SQUAMOUS CELL CARCINOMA

Squamous cell lung carcinoma is a type of non-small cell lung cancer formed from reserve cells–round cells that replaced injured or damaged cells in the lining of the bronchi, the lung’s major air-ways.

Squamous cell tumors usually occur in the lung’s central portions or in one of the main airway branches. These tumors can form cavities in the lung if they grow to a large size.

Paraneoplastic syndrome : hypercalcemia Making up between 25 and 40 percent of all lung cancers, squamous cell carcinoma can spread to

bones, adrenal glands, the liver, small intestine, or brain. Slow growing, this type of cancer can take years to develop from a confined tumor to invasive

cancer. Symptoms develop slowly as well. They include coughing, shortness of breath, wheezing, chest pain, and bloody sputum.

Large Cell Carcinoma ( also called large cell anaplastic)This is an undifferentiated malignant epithelial tumor that lacks the cytologic features of small-cell carcinoma and glandular or squamous differentiation. The cells typically have large nuclei, prominent nucleoli, and a moderate amount of cytoplasm.

2. Patogenesis

PathogenesisIndividual carcinomas of the lung have multiple genetic alterations that are likely be to the result of a stepwise progression from a normal cell toward a malignant tumor. Carcinogenic products in tobacco are clearly involved in this process. Some of the more common genetic alterations associated with lung carcinoma are as follows:

K-ras oncogene: Mutations in this oncogene are found in adenocarcinomas (25%), large cell tumors (20%), and less commonly in squamous cell carcinoma (5%). The mutations correlate with smoking and a poor prognosis.

Myc oncogene: Overexpression of this gene occurs in 10% to 40% of small cell carcinomas but is rare in other types.

Bcl-2: This antiapoptotic protooncogene is expressed in 25% of squamous cell carcinomas and 10% of adenocarcinomas.

Rband p53: Mutations in both of these important tumor suppressor genes are found in 80% of small cell carcinomas. Both genes are somewhat less frequently mutated in nonsmall cell tumors (50% and 25%, respectively).

Deletions in the short arm of chromosome 3 (3p): Such deletions are frequently found in all types of lung cancers.

3. Etiologi

Etologi karsinoma paru sampai sekarang masih belum jelas. Namun Terdapat beberapa factor yg berperan dalam terjadinya Karsinoma Paru yaitu :

Faktor merokok : Terutama pada perokok berat (lebih dari 20 batrang / hari) Faktor pencermaran udara : Udara dicemari oleh bahan Lung Carcinogen

(Asbestos, arsen, nikel, kromat, besi, asap arang batu, uranium,radium, uap minyak)

Faktor penyakit paru yg sdh diderita sebelumnya : Jaringan parut pada paru akibat menderita penyakit paru sebelumnya dapat mengalami perubahan keganasan. Penyakit2 paru tsb antara lain : Infark paru, TB Paru lama, Granuloma pada paru, Asbesitos, Bronkitis Kronik, Fibrosis intersisial Kronik

Faktor perkembangan sel aberrant dalam paru : Karsinoma paru terjadi dari perkembaganan sel aberrant dalam paru yg mempunyai potensi keganasan

5. Manifestasi klinis

Manifestasi klinik

Central or endobronchial growth of the primary tumor may cause cough, hemoptysis, wheeze and stridor, dyspnea, and postobstructive pneumonitis (fever and productive cough).

Peripheral growth of the primary tumor may cause pain from pleural or chest wall involvement, cough, dyspnea on a restrictive basis, and symptoms of lung abscess resulting from tumor cavitation.

Regional spread of tumor in the thorax (by contiguous growth or by metastasis to regional lymph nodes) may cause tracheal obstruction, esophageal compression with dysphagia, recurrent laryngeal nerve paralysis with hoarseness, phrenic nerve paralysis with elevation of the hemidiaphragm and dyspnea, and sympathetic nerve paralysis with Horner’s syndrome (enophthalmos, ptosis,miosis, and ipsilateral loss of sweating)

Malignant pleural effusion often leads to dyspnea. Pancoast’s (or superior sulcus tumor) syndrome results from local extension of a tumor growing in the apex of the lung with involvement of the eighth cervical and first and second thoracic nerves, with shoulder pain that characteristically radiates in the ulnar distribution of the arm, often with radiologic destruction of the first and second ribs. Often Horner’s syndrome and Pancoast’s syndrome coexist.
