Aim: To study the changing profile of lung cancers
in year 1995 and year 2005.
Method: In the combined retrospective and
prospective study, cases of lung cancers were
scanned for distinctive (clinic pathological features,
histropathological types and biological behaviour of
the tumour.
Results: Total 83 diagnosed cases of lung cancer
in 1995 were analysed in details. Male female
ratio was 5.91 : 1, age range was from 35 to 87
years and maximum number of patients were
between 46-64 years. Most common
histopathological type in male was squamous cell
carcinoma; most common histopathological type in
females was adeno-carcinoma. Most common
respiratory symptoms were cough 83.13%,
hemoptysis 37.34% and chest pain 73.49%. Out of
83 patients, 61 patients were smokers, 22 were nonsmokers.
Most common cell type in smokers was
squamous cell carcinoma followed by adenocarcinoma.
Among non-smokers most common cell
type was adeno carcinoma.
All small cell carcinoma patients were
smokers. 61.44% were having clubbing. Commonest
presentation in chest radiograph was mass lesion
(75.90%). Sputum cytology positive 7.22%, post
FOB sputum cytology positive 15.66%, CT guided
biopsy positive 85.36%, FOB guided biopsy positive
74.99%, USG guided biopsy positive 100% were
noted.
This pattern has a few important differences
when compared with recent 1 year study conducted
in the same hospital in 2004 - 2005.
Conclusion: There is an increasing occurrence of
lung cancer with a few definite changing patterns.
Improved diagnostic method may be responsible.
Smoking is the commonest etiological factor.
Although squamous cell carcinoma is commonest
type but adeno carcinoma is also not uncommon.
Statistical analysis of risk factors with PFT
abnormalities among traffic police personnel
using a new risk scoring system

Objective: Identifying pulmonary function
abnormalities among traffic police personnel serving
in the city of Chennai and correlating the same with
their respiratory symptoms and other risk factors as
evaluated with a new scoring system introduced by
us.
Methodology: All the eligible traffic police personnel
were subjected to a respiratory questionnaire
prepared specifically for the study and subsequently
measurement of BP, Oxygen saturation and PFT by
spirometer were done. All of them had a MMR. In
all among 825 traffic police personnel screened, 768
were found eligible for inclusion in the study.
Findings: Pulmonary function abnormalities
correlated well with persons with respiratory
symptoms, age of the individual, smoking habit and
duration of service in polluted environment.
The multiple logistic regression analysis
revealed that respiratory symptoms were found to
be significant independent variables contributing very
significantly for abnormal PFT variables, i.e. FEVI
(or 1.79; p0.02), PEFR (or 1.58; p0.04), FEF 25-75
(or 2.40; p0.0001)
The new computer based scoring system
on risk factors clearly predicts that increase in risk
score is positively associated with increased
proportion of PFT abnormalities in high risk groups.
Conclusion: The newly introduced risk scoring
system will be quite useful in identifying or
predicting pulmonary function abnormalities
among respiratory symptomatics with other
confounding variables. Among persons exposed
to environmental pollution, evaluation of small
airway function may help us to identify their
disability at the earliest.
