Gland-forming adenocarcinoma, which on IHC
will show TTF-1 positivity which is se- en in
majority of pulmonary adenocarcinomas
Histology
Composed of solid groups of large anaplastic
malignant cells. Cells typically have large nu- clei,
prominent nucleoli, and a moderate amo- unt of
cytoplasm.
Histology

areas of keratinization

mass)
Gross
Treatment
The commonest used chemotherapy
combination for small cell is:
Cisplatin and etoposide
CAV (cyclophosphamide, doxorubicin, vincristine)
GemCarbo (gemcitabine and carboplatin)
For relapsed
disease:
ACE (doxorubicin, cyclop- hosphamide
and etoposide)
Topotecan:
for people whose SCLC has relapsed
after treatment, but only if they are
not able to have doxorubicin
Chemotherapy for non-small cell lung cancer (NSCLC)
NSCLC is not as sensitive to chemotherapy as
SCLC.
Surgery or radiotherapy are the main treatments.
Chemotherapy may be given before or after
surgery or radiotherapy
Chemotherapy with either:
Gemcitabine, paclitaxel, docetaxel or vinorelbine
Together with a platinum drug (carboplatin or cisplatin) should be
the first choice for people with advanced NSCLC stage 3 and 4

Bronchoscopy
Bronchoscopy is a test to view the airways and diagnose lung disease. It may also
be used during the treatment of some lung conditions.
Ali's Chief complain was
Hemoptysis
definition
The expectoration of blood or
bloodstained sputum. With massive
hemoptysis the main priorities are to
secure the airway and initiate
emergency resuscit- ative measures
before establishing a diagnosis.
