Abstract
Platinum compounds and vinorelbine have been demonstrated to be active in non-small-cell lung cancer (NSCLC). The aims of the study were to assess tolerability and feasibility of increasing doses of carboplatin (level 1: 300 mg/ m2 on day 1, level 2: 350 mg/m2 on day 1, level 3: 400 mg/m2 on day 1) in combination with a fixed dose of vinorelbine (25 mg/m2 on days 1 and 8) in advanced NSCLC. Forty-two patients entered the study and were evaluable for toxicity and response. The patients were not treated using systemic chemotherapy, had TNM stage IIIB-IV, performance status ECOG 0-2, and their median age was 62 (range 41-70) years. The number of patients evaluable for each dose level was 14. A total of 138 (median 3) courses was administered. Nonhematologic side effects included grade I-II mucositis (9%), neurotoxicity (6%), and infections (4%). Myelotoxicity was manageable and generally of short duration, with 19% of the patients having grade III-IV neutropenia. No significant difference was observed for the three treatment groups. No drug-related death was observed. An objective remission was observed in 10 patients (24% response rate; 95% confidence interval 12-39%), with 5 responses in 14 patients treated with the 400-mg/m2 dose. In conclusion, the combination of carboplatin at a dose of 400 mg/m2 on day 1 and vinorelbine at a dose of 25 mg/m2 on days 1 and 8 can be safely administered as first-line cytotoxic therapy in advanced NSCLC and warrants further evaluation.

Abstract
Malignant pleural mesothelioma has a dismal prognosis and median survival rarely exceeds 12 months. Since multimodality therapy initially showed promising results, we tested the feasibility of a new approach consisting of pleurectomy, immediately followed by intrapleural chemotherapy with cisplatin (100 mg/m(2) day 1) and alpha-interferon (12x10(6) U/m(2) days 1 and 2), followed by 4 cycles of carboplatin, 350 mg/m(2), repeated every 3 weeks and associated to alpha-interferon (3x10(6) U/x3/week). Fourteen patients have been submitted to the protocol and are evaluable for side effects. All patients had surgery and intrapleural chemotherapy, and 4 patients also had systemic chemotherapy. No treatment-related deaths have been observed. Major postoperative complications included chest tube air leak >7 days (1 pt). Intracavitary chemo-immunotherapy-related toxicity was responsible for 7 cases of grade I nephro-toxicity and 2 cases of grade I fever. Grade I-II toxicity from systemic chemotherapy included asthenia (2 cases), fever (3 cases), anemia (2 cases) and neutropenia (2 cases). Grade III-IV toxicity included asthenia (1 case), anemia (2 cases), neutropenia (2 cases) and fever (1 case). Two cases required interruption of systemic chemotherapy for intolerance. Based on these data, systemic chemotherapy has been stopped. In conclusion, our results indicate that pleurectomy plus intra-cavitary cisplatin and interferon is feasible. Since systemic chemotherapy is correlated with severe side effects, a phase II trial with surgery plus intrapleural treatment alone is ongoing.

Abstract
Certain 2-substituted 1H-pyrrolo [3,2-h] quinolines have been prepared and their biological activity in mammalian cells and in some microorganisms have been studied. These compounds represent a simplified ellipticine heterocyclic moiety: in addition they have a different ring condensation, leading to an angular molecular structure instead of a linear one. In mammalian cells all compounds appeared to be able of inducing an antiproliferative effect and an extensive DNA fragmentation, similarly to ellipticine, even if to a reduced extent. The new derivatives behaved in a comparable way also on some microorganisms, such as T2 bacteriophage (which appears to be less sensitive than mammalian cells) and in mutagenesis tests carried out with E. coli WP2 TM9 and S. typhimurium TA 98, which are reverted by base substitution and frame-shift mutagens, respectively. Similarly to the reference compound, all ellipticine analogues appeared to be no mutagenic. The obtained results suggest that they induce the antiproliferative activity in mammalian cells mainly as topoisomerase inhibitors, similarly to ellipticine itself. Therefore, they represent an interesting model to design new potential anticancer drugs.

Abstract
The photobiological activity of a series of psoralen isosters carrying a nitrogen atom at 8 position, new potential drugs for the photochemotherapy of hyperproliferative skin diseases, have been studied; the more active derivatives appeared to be 5,4'-dimethyl-8-azapsoralen and 3,4,4'-trimethyl-8-azapsoralen which induced a strong inhibition of DNA synthesis in Ehrlich ascites cells, very similar to that provoked by 8-methoxypsoralen, the furocoumarin at present used in photochemotherapy. Such compounds induced a small amount of inter-strand DNA cross-links and were non phototoxic when assayed on guinea-pig skin; however, both derivatives appeared to be highly mutagenic in E. coli WP2 TM6. This strain contains the plasmid R46 and it is proficient in DNA repair, and therefore monoadducts do not should be mutagenic in such a strain. Because the first steps of excision, which remove monoadducts, and of the main cross-link repair use the same enzymes (produced by the uvrABC complex), in the presence of a great number of monofunctional lesions, it is possible that there are not sufficient enzyme molecules for removing cross-links according this pathway, which could be repaired by a second one, uvrABC independent and based on glycosilase activity, which works at reduced levels and is much less accurate.

Abstract
The accuracy of bronchial aspiration cytology in typing resectable (stage I-II) lung cancer has been investigated in 100 cases, comparing preoperative cytologic features with pulmonary tumor histology seen at surgery. The accuracy has been 100% for small-cell carcinoma (two cases), 98.8% for squamous-cell carcinoma (86 cases), and 91.6% for adenocarcinoma (12 cases). The overall accuracy rate has been 98%. No case of undifferentiated large-cell carcinoma has been identified. It is suggested that the high accuracy in cytologic typing of operable lung cancer is basically related to adequate preservation of differentiation features, thus allowing for correct identification of most non-small-cell carcinoma. Moreover, the absence in this study of any large-cell carcinoma, compared with its frequency in advanced stage series, would indicate that such a histotype reflects excessive dedifferentiation of an original squamous or glandular form.

Abstract
The increasing demand for upper gastrointestinal endoscopies (184% from 1974 to 1985) led to a review of cases in an attempt to improve the cost-benefit ratio of this diagnostic procedure (E.G.C.). Two parameters were evaluated: the frequency of early gastric cancers and, on the other hand, the incidence of negative endoscopic findings with respect to indications. The increase in the number of endoscopies performed was not matched by an increased frequency of E.G.C. diagnosed: 8.9% in 1974-1979 and 7.5% in 1980-1985 with an E.G.C./endoscopy ratio of 1:218 and 1:415 respectively; in the second period the diagnostic accuracy of endoscopy was enhanced from 42.8% to 100%. The overall frequency of negative endoscopic findings on 500 patients undergoing endoscopy in 1985, was 40.4%. The greatest number of negative findings was observed in patients with non-ulcerous dyspepsia under 50 years of age and in those with ulcerous dyspepsia with prior duodenal ulcer; on the other hand, a significant prevalence of cancerous and precancerous lesions was observed in patients over 50 with non-ulcerous dyspepsia. The results of this study suggest that patients over 50 years with non-ulcerous dyspepsia should receive early endoscopic investigation, in those under 50 an initial therapeutic approach appears reasonable. In the patients with prior duodenal ulcer endoscopy is of limited value for the assessment of response to therapy.
