    Notes: In situ high-angle x-ray diffraction (XRD) measurements during an annealing process and extensive low- and high-angle XRD analysis before and after annealing have been performed to study the influence of annealing on the microstructure of a Ni81Fe19/Ag multilayer film. We concentrate on a detailed description and quantification of induced changes in microstructural properties and on changes in the crystalline structure of sublayers. The observed effects obtained from the high-angle XRD, where superlattice structural refinement and standard powder diffraction methods were used, are utilized to model the changes from microscopic point of view. The low-angle XRD reflectivity measurements were analyzed using a new distorted-wave Born approximation approach which enables to get information about interlayer structure parameters such as interface roughnesses, degree of vertical correlation and lateral correlation length. The presented low-angle and high-angle analysis demonstrates general applicability of x-ray diffraction for complex and quantitative in-situ investigation of structural changes in metallic multilayers during annealing. An effect of lateral scaling for different types of roughness is discussed and a general approach is shown for the case of metallic multilayers. © 1996 American Institute of Physics.

    Description / Table of Contents: Zusammenfassung. Die Lymphknotendissektion ist im Hinblick auf die Stadienzuordnung fester Bestandteil der in kurativer Absicht vorgenommenen Operation bei Bronchialcarcinom. Tumorbefall ipsilateraler mediastinaler Lymphknoten (N2) ist mit einer schlechten Prognose vergesellschaftet. Da die meisten Patienten mit N2-Situation innerhalb 3 Jahren nach Operation an Fernmetastasen versterben, muß angenommen werden, daß ein Befall mediastinaler Lymphknoten bereits Ausdruck einer Generalisation der Tumorerkrankung ist. Daher ist einerseits die Wahrscheinlichkeit eines therapeutischen Effekts einer ausgedehnten Lymphknotendissektion gering, andererseits die Evaluation und Anwendung einer zusätzlichen systemischen Therapie gerechtfertigt.
    Notes: Summary. Any operation for lung cancer that is planned as curative includes dissection of the lymph nodes in the mediastinum in order to allow correct staging of the disease. It is well known that ipsilateral lymph node metastases (N2) mean a poor prognosis. Since most patients with this finding die from metastatic tumor progression within 3 years after the operation, it can be assumed that positive findings in the mediastinal lymph nodes represent generalization of the cancer. Therefore, the probability of a therapeutic effect from more radical removal of lymph nodes in the mediastinum is rather low. On the other hand, it is justified to apply and evaluate additional systemic treatment in these tumor stages.

    Description / Table of Contents: Zusammenfassung. Trotz der Bedeutung des Lymphknotenbefalls für die Klassifikation und Prognose des Bronchialcarcinoms fehlt es bis heute an Standards, nach denen die Qualität der Dissektion zu beurteilen ist. Eine alle ipsilateralen Lymphknotenstationen umfassende Dissektion wird vielerorts nicht für notwendig erachtet. Bei 270 konsekutiven Patienten mit nicht-kleinzelligem Bronchialcarcinom der UICC Stadien (1987) I (n = 115), II (n = 42) und IIIa (n = 113) wurde im Rahmen der kurativen Operation eine vollständige ipsilaterale Lymphknotendissektion durchgeführt, um zu überprüfen, ob eine Beziehung zwischen Ort des Primärtumors und dem Lymphknotenbefallsmuster besteht. In der Gruppe mit N1-Befall (n = 61) zeigten Patienten mit ausschließlich intrapulmonalem Lymphknotenbefall eine höhere 5-Jahres-Überlebensrate (39 %) als die Gruppe mit hilärem oder intrapulmonal/hilärem Befall (21 %). Bei Patienten im Stadium N2 (n = 68) wurde beim Adenocarcinom die hiläre Lymphknotenstation in bis zu 81 % übersprungen. Von den 333 entnommenen Lymphknotenstationen in der Gruppe mit N2-Befall waren 132 infiltriert. Von der Tumorlokalisation oder -größe ließen sich keine Rückschlüsse auf das Befallsmuster der Lymphknoten ziehen. Aufgrund der Variabilität des Lymphknotenbefalls und wegen der Häufigkeit von übersprungenen Lymphknotenstationen („skip metastasis“) ist für kurative Operationen grundsätzlich eine vollständige Dissektion zu fordern.
    Notes: Summary. Despite the important role of lymph node infiltration for the classification and prognosis of non-small-cell lung cancer (NSCLC), no standards exist to evaluate the quality of mediastinal lymphadenectomy. Researches at several centers are not convinced that complete ipsilateral lymphadenectomy is necessary. We investigated 270 consecutive patients undergoing a potential curative operation for NSCLC including complete ipsilateral lymph node dissection in order to ascertain whether or not there is a correlation between tumor localization and lymph node infiltration. Patients were classified into the UICC (1987) stages I (n = 115), II (n = 42), and IIIa (n = 113). In patients with N1-positive lymph nodes (n = 61) we found higher 5-year survival for patients with only intrapulmonary lymph node infiltration (39 %) than for patients with hilar infiltration (21 %). Patients with N2 disease showed skip metastases in up to 81 % of cases. We found that no tumor location predicted the lymph node infiltration. Due to the variability of lymph node infiltration and the frequently occurring skip metastases, complete ipsilateral lymphadenectomy should be the standard for curative operations for NSCLC.
