Cytofluorimetric evaluation of DNA ploidy in lung cancer: a bronchoscopic study.

The study of the biological characteristics of lung cancer is gaining more and more interest both because of their potential role as prognostic indicators and for therapeutic reasons. The DNA content estimated by flow cytometry in surgical samples of non-small cell lung cancer (NSCLC) has already been demonstrated to be correlated with survival in these patients. From July 1990 to February 1992 we analyzed the DNA distribution of bronchoscopic biopsies from 88 patients with lung cancer (18 small cell lung cancer, SCLC, and 68 NSCLC, two unspecified histology). Twenty-eight tumors (34.6%) had a diploid DNA distribution, while 53 were aneuploid (65.4%). A correlation was found between DNA ploidy and survival. Evaluation of the DNA content in bronchoscopic samples in a large series of patients could determine the role of this analysis prior to surgery in NSCLC and its value as a marker with respect to prognosis and response to therapy in SCLC.

[Surgery and chemotherapy in the treatment of primary gastric lymphomas: case review].

Fifty-seven patients with primary gastric non-Hodgkin's lymphoma are here reported. All our patients were treated with surgery as first step procedure. Thirty-six were treated in addition with chemotherapy (four of them with radiotherapy also). Thirty-eight were stage IE and nineteen IIE. According to the Working Formulation, 12 cases were classified as low, 25 intermediate and 20 high malignancy. 55 patients achieved a complete remission (96%) and only 6 relapsed (11%). The 10-year disease-related survival is 89%. Patients treated with combined surgery and chemotherapy were mainly a high risk group (high grade histologic subtype, stage IIE, incomplete resection). Nevertheless the survival of this group was similar to the group initially treated with surgery alone (p = 0.17) in which such unfavorable prognostic factors were not present. Stage, presence of residual tumor after surgery, sex and age did not statistically correlate with survival. Furthermore, there was not statistical difference among the various histological subgroups (p = 0.16). We stress the importance of cooperation among surgeons and oncologists in order to plan an appropriate treatment.
