Miliary opacities diagnosed as lung metastases of a thyroid carcinoma after 13 years of stability.

A 29-year-old man was hospitalized for the diagnosis of clinically asymptomatic miliary opacities discovered 13 years earlier and unchanged since then. Transbronchial biopsy showed metastatic thyroid carcinoma. Thyroid surgery revealed massive local invasion by a papillary carcinoma. We conclude that thyroid carcinoma, whether clinically detectable or not, should be considered in the diagnostic investigation of stable miliary lesions.

Extensive small-cell lung cancer. A randomized comparison of two chemotherapy programs with early crossover in instances of failure. Association pour le Traitement des Tumeurs Intra-Thoraciques (ATTIT).

Two chemotherapy regimens for patients with extensive small-cell lung cancer were prospectively compared in a randomized multicentric trial with crossover. Every four weeks, 60 consecutive previously untreated patients received either DPE (doxorubicin, cisplatin and etoposide), or CIV (carboplatin, ifosfamide and vincristine) with crossover as soon as progression or end of response were observed. Pretreatment characteristics were similar in the two groups. Fifty-seven patients were evaluated for response. The response rate was higher with the DPE regimen both in first-line (for DPE: response rate 62% (18/29), including 17% (5/29) of complete response (CR), and for CIV: response rate 29% (8/28) with no CR, p < 0.02) and in second-line after crossover (for DPE: response rate 45% (9/20) including 5% (1/20) of CR, and for CIV response rate 0%, p < 0.02). Major toxicities were equally frequent in both groups. No significant difference was found between median survival times (9.7 months for the DPE group and 10.4 months for the CIV group). We conclude that: 1) DPE is a more active regimen than CIV, both in first- and second-line; 2) no alternating scheme may be considered with these two combinations. Of particular note is the similar median survival times in the two groups, contrasting with the different activities of the two regimens.

Influence of pretreatment clinical characteristics on the response rate to mitomycin/vindesine/cisplatin (MVP) in unresectable non-small cell lung cancer. ATTIT (Association pour le Traitement des Tumeurs Intra-Thoraciques).

The authors report their experience with the MVP (mitomycin/vindesine/cisplatin) regimen of the Memorial Sloan-Kettering Cancer Center (MSKCC) which showed the highest response rate in non-small cell lung cancer (NSCLC). The aim was to respect the original reported schedule to appreciate its activity, because the same drug combination with dose and schedule variations used by other investigators has failed to reproduce the original report results. 82 consecutive previously untreated patients with unresectable and/or metastatic NSCLC received mitomycin (8 mg/m2 days 1, 29, 71), vindesine (3 mg/m2, days 1, 8, 15, 22, 29, 43, 57, 71) and cisplatin (120 mg/m2, days 1, 29, 71), with evaluation on day 71. 24 objective responses were noted (29%) (2 complete response/22 partial response) (95% CI 19%-39%), without differences according to histology. Differences in median survival were noted according to the performance status and type of response. Overall survival rates in responding patients were similar to those noted with the original schedules. Analysis of selection criteria showed that there were more patients with bone (P less than 0.01) or liver metastases (P less than 0.05), less women (P less than 0.001) and less adenocarcinoma (P less than 0.001) than the MSKCC trial. A dose intensity analysis showed only a minimal difference in the average weekly doses of vindesine (10% lower than MSKCC trial: 1.8 mg/m2 vs. 2.25 mg/m2). Disease improvement, a subjective response criterion used in the MSKCC trial, was probably underestimated in the current study. We conclude that the potential benefit of chemotherapy with a three-drug combination in NSCLC is greatest in patients with stage IIIa and IIIb disease or stage IV disease with a good performance status and a low metastatic volume.

Systemic mast cell disease associated with primary mediastinal germ cell tumor.

The first known case of systemic mast cell disease associated with a germ cell tumor is reported. Six months after the complete remission of a primary mediastinal germ cell tumor treated by chemotherapy and resection, a young man had a series of episodes of hypotension and syncope and, a few months later, a gastric hemorrhage and coagulation disorder. The diagnosis of systemic mast cell disease was made in view of bone marrow and liver biopsies. A transient circulating heparin-like anticoagulant was noted. The occurrence in a short period of these two unusual conditions, given previous knowledge of hematologic disorders associated with germ cell tumors, suggests that the present association is not a coincidence. Systemic mast cell disease should be considered among the hematologic disorders associated with a germ cell tumor.

Histiocytic medullary reticulosis occurring with small cell lung carcinoma.

Haematophagocytic activity is a salient feature of malignant histiocytic medullary reticulosis. This potency has also been observed as an aberrant property of non-histiocytic malignant cells or as a benign histiocytic process in response to infections or malignancies. We report the case of a patient who presented simultaneously with a limited stage small cell lung carcinoma and a fatal reactive form of histiocytosis. We conclude that such a haematophagocytic syndrome may occur in the setting of small cell lung carcinoma s previously described in other malignancies.

Triangular test and randomized trials: practical problems in a small cell lung cancer trial.

The triangular test has been used to monitor survival data from a randomized trial in patients with small cell lung cancer. The results of consecutive interim analyses and the problems met by the data monitoring committee and the co-ordinators are described. The methods as well as the consequences of the early stopping on the analysis and the results of this trial are discussed. From this experience, we believe that statistical stopping rules--only one of the factors to be taken into account when deciding to stop a trial--should be used with caution. Independent data monitoring committees may be useful in helping to review the ongoing results and advise the participants in the trial.
