Lung cancer or bronchogenic carcinoma refers
to tumors originating in the lung parenchyma
or within the bronchi
Lung cancers usually are grouped into two
main types called small cell and non-small
Definition cell. These types of lung cancer grow
differently and are treated differently.
Non-small cell lung cancer is more common
than small cell lung cancer.
EPIDEMIOLOGY OF LUNG CANCER
• A total of 11,256 cases of trachea, bronchus and lung cancers were registered for the period of 2012-
2016 compared with 10,608 cases in 2007-2011 report.
• 68.3% were among males and 31.7% were among females.
• It was the second most common cancer in males(The lifetime risk for males was 1 in 60) and fifth in
females(The lifetime risk for females was 1 in 138)
• According to the latest WHO data published in 2020 Lung Cancers Deaths in Malaysia reached 4,319 or
2.57% of total deaths. The age adjusted Death Rate is 15.25 per 100,000 of population which ranks
Malaysia 77 in the world
• the second most common cause of death due to cancer in the country after breast cancer, and the eighth
most common cause of death from all causes
• The 5-year observed survival rate is only 9.0% (95% confidence interval: 8.4– 9.7), whereas the 5-year
relative survival rate is 11.0% (95% confidence interval: 10.3–11.9)
• Historically, squamous cell carcinoma was the commonest lung cancer cell type. However, over the
years, adenocarcinoma has now replaced squamous cell carcinoma as the commonest lung cancer cell
type.
• An eight-year retrospective study done at University of Malaya Medical Center revealed
adenocarcinoma subtype as the most common cell type in all age groups

Pathophysiology
• The pathophysiology of lung cancer is very complex and
incompletely understood. It is hypothesized that repeated exposure
to carcinogens, such as cigarette smoke leads to dysplasia of lung
epithelium.
• If the exposure continues, it leads to genetic mutations and affects
protein synthesis.
• Then it disrupts the cell cycle and promotes carcinogenesis.
• The most common genetic mutations responsible for lung cancer
development are;
Small cell lung cancer (SCLC): MYC, BCL2, and p53
Non-small cell lung cancer (NSCLC): EGFR, KRAS, and p16
Sign and symptoms
Location Sign and symptoms
Endobronchial Cough, hemoptysis, bronchial obstruction, pneumonitis, pleural effusion
Mediastinal Dyspnea, postprandial cough, wheezing, stridor, hoarseness, and dysphagia
Bronchial and tracheal Bronchial and tracheal obstruction: change air flow and reduce oxygenation
Superior Vena Cava SVC syndrome: distended head and neck vein, blue discoloration of face and arm
Phrenic nerve Diaphragmatic paralysis
Sympathetic chain Horner syndrome; presented with ptosis, anhidrosis and miosis
Superior sulcus Shoulder pain and hand weakness seen branchial plexus involvement (Pancost tumor)
Physical examination
Extrapulmonary findings: adenopathy and clubbing.
Systemic findings: unexplained weight loss and low grade fever.
1. Head and neck
• If the cancer already spread to supraclavicular lymph node, it will give
enlargement to involve nodes.
Lymphatics
•Enlarged ipsilateral supraclavicular lymph nodes are included in limited-stage disease
•Enlarged axillary lymph nodes upstage the diagnosis to extensive stage disease
• Superior sulcus tumors, because of presence at the apex beat of the lung, can
compress the cervical sympathetic plexus causing Horner syndrome. ( ipsilateral
ptosis, miosis, enophthalmos, and anhidrosis.)
2. Cardiovascular examination
• Cardiac findings are usually noted when the tumor causes a
pericardial effusion. Findings can range from simple effusion to
tamponade. Direct cardiac involvement may also occur.
• Examination on extremities may reveal clubbing, cyanosis, or
edema. In the presence of superior vena cava (SVC) obstruction,
the right upper extremity is usually edematous.
• Heart sound is distant on auscultation
• JVP is raised, and paradoxically raised during inspiration
• Pulsus paradoxus classical sign of pericardial tamponade
3. Respiratory system
• Centrally located obstructing tumors can cause collapsed of entire lung
with an absent of breath sound on the side of lesion. Peripheral lesion
can cause individual segment or lobes to collapse, leading to findings
of dullness on percussion and reduce breath sound on auscultation.
• Pleural effusion give rise to characteristic findings of stony dullness and
reduce breath sound, depending on the size.
• Respiratory insufficiency is signaled by dyspnea and increased work of
breathing, retractions, orthopnea, and cyanosis.
Upper airway obstruction: stridor and wheezing.
Lower airway obstruction: asymmetric breath sounds
• Patient usually experience shortness of breath causing used of
accessory muscle for respiration and flaring of the nasal alae
• Distal atelectasis, post obstructive pneumonia and pleural effusion
the examination reveals stony dullness on percussion and reduce
breath sound.
4. Gastrointestinal system
• Liver is a common site of metastatic spread. On physical
examination may reveal yellowish discoloration and
hepatomegaly .
• Most often no specific findings on GI tract on examination.
• Very often patients are asymptomatic but may have elevated
liver enzyme levels.
5. Central Nervous System
• Physical findings depend on the site of the brain lesion.
• Perform fundoscopy to look for sign of raise intracranial pressure,
as well as neurological examination and evaluation of cerebellar
function, coordination and gait.
6. Musculoskeletal System
• Bone is another common site of spread for lung carcinomas.
• Patients may report bone pain, and tender spots may be found
during examination. The examination should include fist
percussion of the spine to look for tender spots, which may
suggest vertebral column metastases.
Investigation: Laboratory Tests How about
tumor marker?
• Complete Blood Count:
to check red/white blood cell & platelets
to check bone marrow and organ function
• Blood Chemistry Test (LFT, U&E): to assess how organs are
functioning such as liver and kidney
• Biopsy histopathological exam
-to determine if the tumor is cancer or not
-to determine the type of cancer
-to determine the grade of cancer (slow or fast)
Investigation: Imaging Tests
• Chest X-Ray: This is often the first test will do to look for any
abnormal areas in the lungs.
• CT scan: Can show the size, shape, and position of any lung
tumors and can help find enlarged lymph nodes.
• MRI scan: used to look for possible spread of lung cancer to
the brain or spinal cord.
• PET scan:- A form of radioactive sugar (known as FDG) is
injected into the blood - Cancer cells needs a lot of energy so
they take up this special sugar.

Investigation: Specialised Tests
• Bronchoscopy: Any abnormal findings may be
biopsied and sent to the lab to determine if any
cancer cells are present in the airways.
• Needle biopsy: can often use a hollow needle
to get a small sample from a suspicious area
(mass).
1. Fine needle aspiration (FNA) - collect cells sample
2. Core needle biopsy – collect core of tissue
3. Open (surgical biopsy) - remove part/all mass.

keratin pearl formation and/or intercellular bridge
• Adenocarcinoma is characterized by formation of glandular
structures by tumor cells with or without mucin secretion
• Large cell carcinoma is characterized by tumor cells with
abundant cytoplasm and lack of granular or
squamous differentiation
• Small cell carcinoma is characterized by clusters/sheets of
small cells with increased NC ratio.
STAGING NSCLC
TAGING NSCLC & PROGNOSI
STAGING SCLC
• Limited
Cancer is in one lung, the mediastinum, and local lymph nodes.
Treatment: chemotherapy plus radiotherapy, and such therapy can cure
20–25% of patients
• Extensive
Cancer has spread beyond one lung, the mediastinum and local lymph
nodes.
Common spread to the liver, bones, adrenal glands, and brain
Treatment: Extensive-stage SCLC is incurable, but chemotherapy can
improve quality of life and prolong life.

Common side effects of treatment
Follow Up
Follow-Up After Therapy for Patients with Non-Small Cell Lung Cancer (NSCLC)
Studies have shown 6.5% annual recurrence rate of NSCLC stage I and SCLC, respectively
• Observation for complications of treatment is recommended for at least 3-6 months
• Follow up with history, physical exam and chest computed tomography (CT) scan with
or without contrast is advised every 6 months for 2-3 years
• Then history, physical exam and low-dose chest CT scan without contrast annually
thereafter for patients with stage I-II NSCLC given primary treatment including surgery
with or without chemotherapy
High-resolution CT scan is recommended 4 years after surgical resection of stages
IA to IIIA NSCLC, followed by low dose computed tomography (LDCT) every year
starting in the 5th year
Peak incidence of recurrence is between 2 and 3 years
• Patients with stage I-II NSCLC --> given primary treatment with radiotherapy
• Patients diagnosed with stage III or IV NSCLC --> history, PE, and chest CT scan with or
without contrast is advised every 3-6 months for 3 years
Then history, PE and chest CT scan with or without contrast every 6 months for 2
years, then history and PE with low-dose chest CT scan without contrast annually
• Patients with advanced or metastatic disease, response to initial therapy should be
assessed after 2 cycles using CT with or without contrast on previously identified tumor
sites, then every 2-4 cycles or when clinically indicated
Assessment of response to subsequent therapy should be done every 6-12 weeks
using CT with or without contrast on previously identified tumor sites
• It is recommended that all screening and follow-up CT scans should be performed at
a dose of 100-120 kVp and 40-60 mAs or less
• Biomarkers
ALK fusion oncogene
ROS1 gene rearrangements
BRAF V600E mutations
EGFR mutations
PD-1 ligand
*utilized to predict treatment outcome or disease prognosis
• Patients who smoke should be advised to quit
Follow-Up After Therapy for Patients with Small Cell Lung Cancer (SCLC)
• Patients with limited disease (LD) --> follow up every 3 months for the 1st year or two,
then every 6 months during the 3rd year, then annually after recovery
• Patients with extensive disease (ED) --> follow up every 2 months during the 1st year,
then every 3-4 months on years 2-3, then every 6 months on years 4-5, then annually
• It is recommended that all screening and follow-up CT scans should be performed at a
dose of 100-120 kVp and 40-60 mAs or less
• Response assessment using chest, pelvic and abdominal CT scan with contrast, or
brain MRI or CT with contrast depends on previous treatment given and stage of
patient's disease:
LD SCLC patients given adjuvant chemotherapy or chemoradiotherapy: Only
after completion of treatments
LD SCLC patients given systemic therapy or chemoradiotherapy: After every 2
cycles of systemic therapy and at completion of treatments
ED SCLC patients given systemic therapy: After every 2-3 cycles of systemic
therapy and at completion of therapy
• Response assessment of ED SCLC patients with asymptomatic brain metastasis
receiving systemic therapy prior to WBRT should undergo brain magnetic
resonance imaging (MRI) or CT scan with contrast every 2 cycles of chemotherapy
and after completion of therapy
Palliative Care for Lung Cancer
• Procedures to open airways
• Medications to treat pain
• Medications to suppress a cough, open closed airways and improve
breathing
• Emotional support and counselling
• Nutritional supplements to reduce weight loss
• Medications to reduce nausea
• Integrative services like massage, mindfulness
