Fifty eight patients with small cell carcinoma of the lung were treated with a combined-modality regimen: chemotherapy with adriamycin, cyclophosphamide, and vincristine; BCG immunotherapy; radiotherapy to the lung primary and prophylactic cranial irradiation. Ninteen patients had limited disease, and 39 had extensive disease. There were 27 (48%) partial remissions and 23 (41%) complete remissions, and median survival was 51 wk. Initial performance status and extent of disease had a definite effect on survival. Only 1 patient developed CNS metastases on prophylactic cranial irradiation. Five of 19 patients (26%) with limited disease remain alive and in complete remission at 26-45+ mo. It is becoming clear from this and other recent studies that we can significantly prolong median survival in small cell lung cancer. However, even more important is the fact that limited-extent small cell lung cancer may be a potentially curable disease.

Despite frequent metastatic involvement of the pancreas at postmortem examination in patients with small cell lung cancer, clinically observed pancreatitis due to metastatic pancreatic tumor rarely has been reported. This communication describes three cases of clinical acute pancreatitis occurring in a consecutive series of 40 patients with oat cell lung cancer. This complication may appear either as the initial manifestation of the neoplasm or during a recrudescent phase of the malignant growth. The diagnosis should be suspected in the presence of the clinical, laboratory, and radiologic features of acute pancreatitis in patients with known small cell carcinoma of the lung, especially if there is evidence of progression of the neoplastic disease elsewhere and no response to conservative medical management. Aggressive treatment with polychemotherapy can produce rapid clinical improvement and useful prolongation of survival.

Survival and histologic subtype were compared in 61 patients with small cell anaplastic lung cancer. Patients with lymphocyte-like (oat cell) and fusiform histologies treated with chemotherapy had longer median survivals than the polygonal and other varieties on the same treatment. Likewise, when detectable disease was confined to the chest and supraclavicular nodes, the patients with lymphocyte-like and fusiform types lived longer. The improved survival in the lymphocyte-like and fusiform categories accounted for most of our improved overall median survival rates with the COPP regimen in small cell lung cancer. Survival in the polygonal and other types was not appreciably different from that seen in non-small cell lung cancer (squamous and adenocarcinoma). It may be possible to refine treatment plans on the basis of cell type so as to further increase survival in small cell anaplastic lung carcinoma.

The EORTC Lung Cancer Cooperative group performed a randomised phase II study in patients with small cell lung cancer comparing the standard cyclophosphamide/doxorubicin/etoposide (CDE) regimen with two regimens containing the new and active cisplatin derivative, carboplatin, 400 mg/m2 in combination with ifosfamide, a drug without important myelotoxicity, at a dose of 5 g/m2 (IMP) or the non-myelotoxic drug vincristine twice 2 mg (VP). Of 178 evaluable patients, 63 received CDE [30 limited disease (LD), 33 extensive disease (ED)], 55 received IMP (22 LD, 33 ED) and 60 (26 LD, 34 ED) were treated with VP. The response duration was not statistically different: CDE 31 weeks, IMP 29 weeks and VP 21 weeks. The time to progression after CEE was 28 weeks, IMP 24 weeks and VP 17 weeks. This was significantly shorter after VP than after CDE (P = 0.017). The 60% response rate of the VP combination was low compared with CDE (83%) and IMP (77%). Toxicity of all three regimens was acceptable, and dose reduction for myelosuppression was necessary in only a minority of the patients. We conclude from this study that the combination of carboplatin, at the maximally tolerated dose of 400 mg/m2, in combination with ifosfamide 5 g/m2, is an active regimen with efficacy comparable with the standard CDE regimen.

A study of 149 light microscopic tissue slides from 147 patients with recorded initial diagnoses of small cell lung cancer (SCLC) (114 cases) and undifferentiated carcinoma (35 cases) was undertaken to test the reproducibility and prognostic impact of a new histopathologic subclassification of SCLC proposed by the Pathology Panel of the International Association for the Study of Lung Cancer (IASLC). This study was further designed to test the impact of clinical stage, age, sex, and race on survival. The tissue slides were blindly reclassified as SCLC or non-SCLC by a panel of five pathologists with no knowledge of the initial diagnosis. The SCLCs were divided into the three subtypes outlined by the IASLC pathology panel: small (classic or pure), mixed (small cell/large cell), and combined (small cell/squamous carcinoma or small cell/adenocarcinoma). Small cell lung cancer was clinically staged as local, regional, or distant. Consensus diagnosis (defined as agreement by at least three of the five pathologists) was achieved in 144 (96.6%) of the 149 cases. Of these 144 cases, 124 were reclassified as SCLC (115 [92.8%] small, five [4.0%] mixed, and four [3.2%] combined) and 20 were classified as non-SCLC. The median lengths of survival for the small, mixed, and combined subtypes were 225, 1,110, and 203 days, respectively (P = .025). Adequate staging data were available in 123 of the 124 SCLC cases. Of the 123 SCLC cases, 27 (21.9%) were local, 22 (17.9%) were regional, and 74 (60.2%) were distant stage. The median lengths of survival for the local, regional, and distant stages were 428, 251, and 111 days, respectively. This association was highly significant (P = .0001). We conclude that stage is the major determinant of survival in SCLC. Mixed subtypes had significantly longer survival times than the small or combined subtypes (P = .025). Survival times were longer for women than for men, and the survival time difference between men and women was significant (P = .0028). We found no significant differences in survival according to age or race.

A phase II clinical study of 254-S, a new anticancer platinum complex, for primary lung cancer was conducted by the 254-S Lung Cancer Study Group consisting of 15 institutions nation-wide. Considering the results of the phase I clinical study, 254-S was administered at 100 mg/m2 by intravenous drip infusion and this administration was repeated at least 2 times at 4-week intervals. Of 75 patients registered, 61 patients consisting of 22 with small cell lung cancer (SCLC) and 39 with non-small cell lung cancer (NSCLC) were evaluable for complete tumor response. Partial response (PR) was obtained in 17 patients, for a 27.9% response rate. The response rate for SCLC was 40.9% (9 PR in 22 patients) and that for NSCLC was 20.5% (8 PR in 39 patients). In SCLC patients with no prior chemotherapy, a 50.0% (5 PR in 10 patients) response rate was obtained. In those with prior chemotherapy, the response rate was 33.3% (4 PR in 12 patients). In NSCLC patients with no prior chemotherapy, a 22.6% (7 PR in 31 patients) response rate was obtained. In hose with prior chemotherapy, the response rate was 12.5% (1 PR in 8 patients). Major toxic effects observed were hematotoxicity such as thrombocytopenia and leukopenia, and gastrointestinal toxicity such as nausea, vomiting and anorexia. Nephrotoxicity observed was mild and infrequent in spite of the low-volume hydration performed. Based on these results, it was concluded that 254-S is a useful anticancer agent for the treatment of primary lung cancer.

A total of 184 patients with small cell lung cancer (SCLC) including 18 patients with ipsilateral pleural effusion as the only evidence of metastasis beyond the primary tumor site (PL), 84 patients with limited disease (LD), and 82 patients with extensive disease (ED) were treated at the Osaka Prefectural Habikino Hospital between December 1982 and June 1990. The median survival time for patients with PL was 51 weeks; for the patients with LD, 51 weeks; and for the patients with ED, 34 weeks. The survival of PL patients was significantly better than that of ED patients (P less than 0.05), and did not differ from that of LD patients. The response rate of PL patients was not significantly different from the response rates observed in LD- and ED-patients. There was no significant difference in survival or response rate between patients with cytologically positive and those with cytologically negative PL. Ipsilateral pleural effusion was not found to be a independent prognostic factor for survival from multivariate analysis in LD patients. These results indicate that the classification of limited disease small cell lung cancer should include patients with ipsilateral pleural effusion, as suggested by the consensus report at the International Association for the Study of Lung Cancer (IASLC) Workshop in 1989.

Gastrin has been postulated to be a physiological growth factor, but compelling in vitro evidence of this has been difficult to obtain. In the present study we investigated whether small cell lung carcinoma cell lines could provide a useful model system to study the effects of gastrin on signal transduction and cell proliferation in vitro. We found that the addition of gastrin to small cell lung cancer cells loaded with the fluorescent Ca2+ indicator fura 2-tetraacetoxymethylester causes a rapid and transient increase in the intracellular concentration of Ca2+ ([Ca2+]i) followed by homologous desensitization. The [Ca2+]i response was especially prominent in the small cell lung carcinoma cell line H510. In this cell line, gastrin I, gastrin II, cholecystokinin residues 26-33 (CCK-8), and unsulfated CCK-8 increased [Ca2+]i in a concentration-dependent fashion with half-maximum effects at 7, 2.5, 3, and 5 nM, respectively. The Ca(2+)-mobilizing effects of gastrin and CCK-8 were prevented by proglumide, benzotript, and the specific gastrin/CCKB receptor antagonist L365260. Gastrin stimulated the clonal growth of H510 cells in semisolid (agarose-containing) medium, increasing both the number and the size of the colonies. Gastrin and CCK agonists were equally effective in promoting clonal growth. The broad-spectrum neuropeptide antagonists [D-Arg1,D-Phe5,D-Trp7,9,Leu11] substance P and [Arg6,D-Trp7,9,MePhe8] substance P (6-11) markedly inhibited gastrin-stimulated Ca2+ mobilization and clonal growth. These results show that gastrin acts as a direct growth factor through gastrin/CCKB receptors and demonstrate, for the first time, that these peptides can stimulate the proliferation of cells outside the gastrointestinal tract.
