ABSTRACT
PURPOSE: We determine if post-chemotherapy resection of residual retroperitoneal and chest tumor under the same anesthetic is reasonable based on tumor pathology and morbidity, and if the finding of necrosis in the abdomen allows observation of chest tumor. MATERIALS AND METHODS: We retrospectively reviewed 143 post-chemotherapy patients who underwent resection of residual retroperitoneal and chest disease under the same anesthetic. RESULTS: Retroperitoneal pathology was generally predictive of chest pathology. Concordance existed in 77.5% of patients with necrosis, 70% with teratoma and 69% with cancer of the abdomen. However, the correlation was much stronger (86%) in predicting necrosis/fibrosis if cases were categorized as uncomplicated by Indiana University criteria. Although the morbidity of the combined approach is higher than that of standard post-chemotherapy retroperitoneal lymph node dissection, it was acceptable. CONCLUSIONS: The morbidity of post-chemotherapy retroperitoneal lymph node dissection and resection of chest disease under the same anesthetic is acceptable. Retroperitoneal pathology generally predicts chest pathology but this correlation is much stronger if the case is uncomplicated based on our criteria. In an uncomplicated case the discovery of necrosis of the abdomen allows observation of chest tumor.

Alpha-NiSO4 x 6H2O crystals were studied by magnetic circular dichroism (MCD) and absorption spectra measurements in the range lambda = 185-3300nm. The results show that there are three aborption bands, of which the peaks are related to the d-d transitions from the ground state to the excited states. The weak peaks of a progression of the three members were observed between the principal structures lambda = 654nm and lambda = 713nm due to spin-orbit coupling interacion. The weak peaks of a progression of four members were also observed around the new absorption peak at lambda = 585nm in MCD spectra.
