                                            Objective: to establish the feasibility of a lung cancer screening program on a
                                            rural Irish population using low-dose CT scanning.
                                            Participants: men and women meeting inclusion criteria (45-65 yr olds, the ability
                                            to climb 2 flights of stairs and a 20 or more pack year history of smoking) and
                                            exclusion criteria (acute illness or clinical suspicion of cancer).
                                            Rationale: lung cancer remains a major cause of cancer mortality. Late disease
                                            presentation challenges us to identify effective means of early detection in asymp-
                                            tomatic cases. To date detection rates have been extremely low and selection bias has
                                            affected the quality of many previous screening studies, as well as a high incidence
                                            of false positives due to incidental fungal lung pathology. No study has investigated
                                            the effects of a screening program on a population with a high prevalence of heavy
                                            smoking together with a relatively low incidence of incidental lung pathology.
                                            These factors are characteristic of the rural Northern Irish population and coupled
                                            with accessible CT scanning facilities and surgical support, we feel this presents
                                            an opportunity to contribute to the debate surrounding lung cancer screening.
                                            Specific issues under consideration: selection methods that minimise selection
                                            bias; sample size sufficient for clinical significance; securing £140,000 ( 203,000)
                                            funding for a 2 year pilot study; ethical approval.
                                            Main outcome measures: number, stage and prevalence of asymptomatic lung
                                            cancers in the study population; numbers and proportion of detected lung cancer
                                            patients referred and undergoing surgery; sensitivity and specificity of the screening
                                            test; the 5 year survival rate for detected cancers.

                                            synchronous bronchial carcinoma

                                            Slovenia

                                            We wanted to find out the sensitivity of auto fluorescence, flexible and video
                                            bronchoscopy for preneoplastic changes and synchronous bronchial carcinoma.
                                            One hundred and one patients, 87 male, 20 female, age 64, 5±9, 4 years were
                                            examined: 50 with video and 51 with flexible bronchoscope with Storz D light/auto
                                            fluorescence.
                                            979 biopsies were performed at 252 biopsy sites. We histologically confirmed inva-
                                            sive carcinoma in 91 patients. Additionally carcinoma was confirmed at 17 biopsy
                                            sites; synchronous bronchial carcinoma in 5. We found preneoplastic changes at
                                            11 biopsy sites.
                                            Sensitivity of auto fluorescence (0, 92), video (0,91) and flexible bronchoscope
                                            (0,84) for invasive carcinoma was the same. Sensitivity of auto fluorescence bron-
                                            choscope (0,89) was higher for the preneoplastic lesions than of video and flexible
                                            bronchoscope (0,45).
                                            Specificity of auto fluorescence bronchoscope (0,69) was lower (p>0,05) than
                                            specificity of video (0,88) and flexible (0,75) bronchoscope.
                                            Auto fluorescence bronchoscope was more sensitive and less specific for preneo-
                                            plastic lesions. Sensitivity of auto fluorescence, flexible and video bronchoscope
                                            for invasive bronchial carcinoma was the same.
                                            In central bronchial carcinoma auto fluorescence bronchoscope can be used to find
                                            additional premalignant changes of bronchial mucosa.

                                            Introduction: Radiologists reporting outpatient CXR have the facility to refer
                                            patients to Chest Clinic without referring back to the primary care physician. This
                                            facility exists mainly to ensure rapid investigation of suspected lung cancer.
                                            Aims: 1 To determine reason for referral, and compare with final diagnosis
                                            2 To categorise investigation pathways
                                            3 To quantify investigations generated
                                            Method: Radiology referrals to Ninewells from April to September 2005 (n=52)
                                            were selected from the Lung Cancer Management database. Types, dates and
                                            results of investigations were collected from the computerised results system.

Backgrounds: As in Europe and US, patients with malignant pleural mesothelioma
(MPM) is increasing and becoming socio-economical burden in Japan. Although
several chemotherapeutic agents are at hand, it is sometimes difficult to assess the
disease activity from imaging study.
Objective: To assess the usefulness of Cyfra 21-1 (CYFRA; cytokeratin 19 frag-
ments) as a disease activity marker, we retrospectively analyzed MPM patients in
a Japanese community hospital.
Patients: From Jan. 2000 to Dec. 2005, we experienced 16 patients with MPM in
Yokohama Municipal Citizen’s Hospital.
Results: The age of the patients are 46 to 76 (median 66) years old. Nine had
definite history of asbestos exposure. Pathologically, five had epithelial type and
three had sarcomatous type. Nine patients were treated with chemotherapy (six                 Conclusion: Patients with serum concentration of cyfra 21>6ng/ml have shorter
