Evolution of surface-based deformable image registration for adaptive radiotherapy of non-small cell lung cancer (NSCLC)

<p>Abstract</p> <p>Background</p> <p>To evaluate the performance of surface-based deformable image registration (DR) for adaptive radiotherapy of non-small cell lung cancer (NSCLC).</p> <p>Methods</p> <p>Based on 13 patients with locally advanced NSCLC, CT images acquired at treatment planning, midway and the end of the radio- (n = 1) or radiochemotherapy (n = 12) course were used for evaluation of DR. All CT images were manually [gross tumor volume (GTV)] and automatically [organs-at-risk (OAR) lung, spinal cord, vertebral spine, trachea, aorta, outline] segmented. Contours were transformed into 3D meshes using the Pinnacle treatment planning system and corresponding mesh points defined control points for DR with interpolation within the structures. Using these deformation maps, follow-up CT images were transformed into the planning images and compared with the original planning CT images.</p> <p>Results</p> <p>A progressive tumor shrinkage was observed with median GTV volumes of 170 cm³(range 42 cm³- 353 cm³), 124 cm³(19 cm³- 325 cm³) and 100 cm³(10 cm³- 270 cm³) at treatment planning, mid-way and at the end of treatment. Without DR, correlation coefficients (CC) were 0.76 ± 0.11 and 0.74 ± 0.10 for comparison of the planning CT and the CT images acquired mid-way and at the end of treatment, respectively; DR significantly improved the CC to 0.88 ± 0.03 and 0.86 ± 0.05 (p = 0.001), respectively. With manual landmark registration as reference, DR reduced uncertainties on the GTV surface from 11.8 mm ± 5.1 mm to 2.9 mm ± 1.2 mm. Regarding the carina and intrapulmonary vessel bifurcations, DR reduced uncertainties by about 40% with residual errors of 4 mm to 6 mm on average. Severe deformation artefacts were observed in patients with resolving atelectasis and pleural effusion, in one patient, where the tumor was located around large bronchi and separate segmentation of the GTV and OARs was not possible, and in one patient, where no clear shrinkage but more a decay of the tumor was observed.</p> <p>Discussion</p> <p>The surface-based DR performed accurately for the majority of the patients with locally advanced NSCLC. However, morphological response patterns were identified, where results of the surface-based DR are uncertain.</p

Individual and spousal education, mortality and life expectancy in Switzerland: a national cohort study.

BACKGROUND Household measures of socioeconomic position may better account for the shared nature of material resources, lifestyle, and social position of cohabiting persons, but household measures of education are rarely used. We aimed to evaluate the association of combined educational attainment of married couples on mortality and life expectancy in Switzerland. METHODS The study included 3 496 163 ever-married persons aged ≥30 years. The 2000 census was linked to mortality records through 2008. Mortality by combined educational attainment was assessed by gender-age-specific HRs, with 95% CIs from adjusted models, life expectancy was derived using abridged life tables. RESULTS Having a less educated partner was associated with increased mortality. For example, the HR comparing men aged 50-64 years with tertiary education married to women with tertiary education to men with compulsory education married to women with compulsory education was 2.05 (1.92-2.18). The estimated remaining life expectancy in tertiary educated men aged 30 years married to women with tertiary education was 4.6 years longer than in men with compulsory education married to women with compulsory education. The gradient based on individual education was less steep: the HR comparing men aged 50-64 years with tertiary education with men with compulsory education was 1.74 (1.67-1.81). CONCLUSIONS Using individual educational attainment of married persons is common in epidemiological research, but may underestimate the combined effect of education on mortality and life expectancy. These findings are relevant to epidemiologic studies examining socio-demographic characteristics or aiming to adjust results for these characteristics

Arbeitsklassifizierung - ein Verfahren der Anforderungsermittlung (Arbeitsbewertung) in Betrieben der DDR

"In diesem Beitrag wird die Entwicklung der Arbeitsklassifizierung als verbindliche Methode der Anforderungsbewertung und Eingruppierung für Arbeitsaufgaben in Industrie und Bauwesen sowie in weiteren materiellen Bereichen der DDR dargelegt. Im Zusammenhang mit der Erläuterung der Zielstellung und Grundkonzeption der Arbeitsklassifizierung erfolgt eine vergleichende Einschätzung zu Verfahren der Anforderungsbewertung in der BRD, um Gemeinsamkeiten bzw. Unterschiede deutlich zu machen. Den Schwerpunkt des Beitrag bilden Ausführungen zu den in der Praxis genutzten methodischen Unterlagen für die Anforderungsermittlung und -bewertung, zu den dabei gesammelten Erfahrungen und aufgetretenen Problemen sowie zu Vorstellungen über die weitere Entwicklung der Arbeitsklassifizierung. Der Artikel soll auch als Diskussionsbeitrag zur Gestaltung künftiger Systeme der Anforderungsbewertung mit verstanden werden." (Autorenreferat
