Single brain metastasis of non-small cell lung carcinoma. Study of survival among 54 patients Demange L, Tack L, Morel M et al. Deparmeni ofRadiamn Oncology. /n.rritul Jean-Godinor. 5110 Reim. Br J Neurosurg 1989;3:81-8. WC sludled 54 patients treated for non-small cell lung carcinoma with smglc brain metastasis presenting between 1980 and 1985. Betler survival was obtained in cases of patients presenling a fair neurological condiuon who were treated by surgery. Histological condition and date of onset of metastasis had no significant influence on survival. Combmed treamem of both primary lung tumour and brain metastasis was a favourable prognosis element, and surgical resection of both locaoons led to the best results in terms of duration and quality of survival. &topic production of parathyroid hormone by small cell lung cancer in a patient with hypercalcemia Yoshimoto K, Yamasaki R, Sakai H et al. Firs1 Depnrrmen~ oflnternal Med~cine,SchoolofMedic~ne,Universilyof~~~kushima,7‘okushimo 770 J Clin Endocrinol Memb 1989:68:976-X1. Sevcrc hypcrcalcemia (serum calcium,4.37-4.84 nmol/L) was found in a 70-yr-old man who had a small cell carcinoma of the lung with multiple melaslascs. The plasma immunoreactlve PTH concentration was markedly elevated, as measured in three different PTH assays [Ntcrmmal PTH 4,650 rig/L (normal, 230.630): midreglon PTH, 13,850 rig/L (normal, 180-560); C-terminal PTH, 9,900 rig/L (normal, < 1,300)], but al autopsy the paralhyroid glands were histologically normal. The PTH conccnuation of a liver metastasis was 503.5 rig/g wel WI (normal liver, < 4.2.5.9), and the PTH m Ihe tumor cxuact elutcd at ncarll IhcsamcposiGonassynlhctic humanPTH-(I-84)ongclfiltration chromatography. Northern blot analysis revealed PTH mRNA in the tumor as a single band of 0.9 kilobase. Thcsc results indlcatc thar the cctopic PTH producxion by the lung cancer was the cause of hypercalcemla in this patient. Concurrent anaplastic bronchial cancer in identical twin brothers Norcs JM, Dalayeun J, Chcbat J, Dicudonnc P, Nenna AD. Deparrmenr oflnlernal Medicine, University of Paris. tlopilai Raymond-Poincare. F-92380 Garches. Respiration 1989;55:56-9. After having observed homozygotic identical twm brothers who simultaneously suffered from anaplastic bronchial cancer which rapldly led to death in both cases, [he authors assessthe frequency of such cases. RCVICWof Ihe available literature failed to produce identical observations, although 4 cases of twms suffering from bronchial cancer witi diffcrmg hlstologies (3 epidcrmoidal and 1bronchiole-alveolar) wcrc noted. Statistics show that in the arca where the observed twins were living. anaplaslic cancer occurs each year m 0.39 of 53.year-old men. The casts of these twins therefore support the notlon of the role of gcncLlc factors m Ihe dctcrminatlon of bronchial cancer.
