Abstract

The aim of this study was to evaluate FDG-PET for assessment of therapy response and for prediction of patient outcome after neo-adjuvant radio-chemotherapy (NARCT) of advanced non-small cell lung cancer (NSCLC). Seventy patients with histologically proven stage III NSCLC underwent FDG-PET investigations before and after NARCT. Changes in FDG uptake and PET findings after completion of NARCT were compared with (1) the histology of tumour samples obtained at surgery or repeat mediastinoscopy, and (2) treatment results in terms of achieved operability and long-term survival. The mean average FDG uptake of the primary tumours in the patient group decreased significantly during NARCT ( p = 0.004). Sensitivity, specificity and overall accuracy of FDG-PET were 94.5%, 80% and 91%, respectively, for the detection of residual viable primary tumour, and 77%, 68% and 73%, respectively, for the presence of lymph node metastases. A negative PET scan or a reduction in the standardised uptake value (SUV) of more than 80% was the best predictive factor for a favourable outcome of further treatment. Progressive disease according to PET (new tumour manifestations or increasing SUV) was significantly correlated with an unfavourable outcome ( p = 0.005). In this subgroup, survival of patients who underwent surgery was not significantly different from survival among those who did not undergo surgery, whereas for the whole patient group, complete tumour resection had a significant influence on outcome. FDG-PET is suitable to assess response to NARCT in patients with stage III NSCLC accurately. It was highly predictive for treatment outcome and patient survival. PET may be helpful in improving restaging after NARCT by allowing reliable assessment of residual tumour viability. [ABSTRACT FROM AUTHOR]

22. Rickettsia typhiInfection with Interstitial Pneumonia in a Traveler Treated with Moxifloxacin

Author

Schulze, Marco H., Keller, Christian, Müller, Andreas, Ziegler, Uwe, Langen, Heinz-Jakob, Hegasy, Guido, and Stich, August

Abstract

ABSTRACTRickettsial diseases may play an important part in the differential diagnosis of fever in returned travelers. The initial empirical treatment needs to take Rickettsiaspecies into consideration to avoid the development of life-threatening courses. Here, we present a case of interstitial pneumonia associated with Rickettsia typhiinfection treated with moxifloxacin.

23. Isolation of Salmonella entericaSerotype Newport from a Partly Ruptured Splenic Abscess in a Traveler Returning from Zanzibar

Author

Tappe, Dennis, Mu¨ller, Andreas, Langen, Heinz-Jakob, Frosch, Matthias, and Stich, August

Abstract

ABSTRACTSalmonella entericasubsp. entericaserotype Newport is a pathogen of growing importance because of its epidemic spread in dairy cattle and increasing rate of antimicrobial resistance. Human infections, however, are rare. We report a case of a splenic abscess in a young traveler returning from East Africa.

24. Molecular Detection of Campylobacter jejunias a Cause of Culture-Negative Spondylodiscitis

Author

Tappe, Dennis, Schulze, Marco H., Oesterlein, Anett, Abele-Horn, Marianne, Baron, Stefan, Durchholz, Daniel, Langen, Heinz-Jakob, Jany, Berthold, and Schoen, Christoph

Abstract

ABSTRACTSpondylodiscitis caused by Campylobacterspecies is a rare disease which is most often caused by Campylobacter fetus. We report a case of culture-negative spondylodiscitis and a psoas abscess due to Campylobacter jejuniin a 68-year-old woman, as revealed by 16S rRNA gene and Campylobacter-specific PCRs from biopsied tissue.
