Ann Thorac surg 1995:59-412-5. lmmunohistochemical expression of Lewis(y). sialyl Lewsfxl. and
sialyl Lms’ were examined in relation to blood vessel invasion and pmgnos~s in 133 patients with stage I non-small all lung cancer who hada curative resection fmm 198010 1991. Expression ofsialyl Lewis(x) in adenocarcinomas was higher than m squamous cell and large cell carcinomas. and Lewis(y) immunoreactivity was the highest among the th= antigens. The frequency ofblmd vessel mvasion was stgnilicantly hrgher m tumors with expression of Lewis@) or smlyl Lews antagen (sialyl Lewis(x) or sialyl Lewir’). however. Lms@) expression was even more sign&ant. The postoperat,ve survival was signilicantly shorter when tumors expressed both the Lewiz4y) and slalyl Laws antigen However, the survival of patients with either Lewis(y) or sialyl Lewis antigen expression was similar to that of patients whose tunwrs did mt express either the Lzws&) or sialyl Lewis antigens These results suggest that Lewis&) and sialyl Lewis antigen may be of prognostic ~aluc br metaslatic paential but have different functional roles in tumor cells

AZ 85259 S&n Dia& Pathol i99Xi2:30-44 As pathologists. we are most concerned about wercalbng reactive
changes in the lung as carcinoma and the fact that malignant prwxsses may be misinterpreted 8s knign processes in the lung IS less well rewgnized. This review wvem five such lesmns Welldifferentiated adenocarcinomas. especially bronchioloalvcolar carcinomas, are frequently undcrc8lk-d. particularly in small biopsy and cytology specimens. In swh cases. one must pay particular attention to the uniformity and monotony of the epithelium even tbougb it may be extremely well differentiated Spindk cell carcinomas may have neaosis end cavitatmn intersbtml growth and a rcac~lve tibrcblastic react on and thus be mistaken as organizing itiammatory processes. Careful
attention to the atypical cytological features. prominent vascular invasion, and getting immunohistochcmical suppons helps in recognizing them. Lymph&d lesions of the lung present a number of prcbkmssmall lympkaytic IympbornasandHcd&in*sdiseaseareoften misinterpreted as inflammatory processa. lntra~ lymphomatosis in the lung may be misinterpreted as an interstitial pneumonia if one does not appreciate the atypical lymphoid cells with n the capillaries The desmoplastic variant of sarcomatous mesothclioma may be extremely diffcult to diagmx, bxause large pxticms of the tumor are composed of blandappearing fibrous tissue. A case of dcsmoplastic mesothelioma presenting predominantly as a nxdiastinal mass is discussed, and problems in differentral diagnosis are outlined. Angiosarcamas are rare tumors. but an appreciable percentage of them presentaspulmonary meurnasa which mayk interpre+edaspulmonary hemorrhage or organizing infarction. The clinical and radiographic pattern, uwally mimicking mete static dircase. and the fact that atypical spindlecellsacludesmallpllmonaryarlcricswithsunoundingalumlar hemorrhage are clues to the recognition of these lesions.

It has been suggested that a proponron of patrents wrth cancer have an ongmng acute phase response indicated by a raised C-rcact~ve praein (CRP) To examme whether an aate phaeprotcin response IL aswclated with circulating interleukm-6 (IL-61 wnczntrations ,n patients wth lung cancer, we measured serum levels of CRP and interieukin (IL)-5 in 176 patrents with lung cancer and 48 parents with other pulmonary dwases (28 d,Ifuse pulmonary mliltrates, I5 bemgn lung tumors. and 5 broncbal asthmas) Serum CRP was &tmable ( 2.5 mg/liter) in 57 4% of patients with lung cancer. 78.6%of patients wrth d&rsz pulmonary infiltrates. 46 1% of patients mth benign lung tumors. and 40 0% of parents with bmnchlalasthma Serum ILd wasdeteaablem all pabents by a hrghly sensmve enzyme-mununaassay. the concentratmn ranging from0 126to35.llSpglmI. AlthoughUlerewarnos~gn~f~tdiU~rcncc in serum ILd levels among the histologrc types of lung can~cr. the IL- 6 concentratmn was signifunlly hrgher in patients wth advanced cancers than m those with early ones Correlation anal~scs shoucd that there was no significant relationshap between the CRP and IL-6 mncenlrahons in the 176 patients wth lung cancer (r = 0 212.
