ABSTRACT
A multi-institutional phase II trial was conducted to evaluate the efficacy and toxicity of combination chemotherapy consisting of gemcitabine and UFT, which is composed of tegafur and uracil, for non-small-cell lung cancer (NSCLC) patients. Patients with advanced NSCLC received an oral administration of UFT (tegafur 200 mg m(-2)) b.i.d. from days 1 to 14 and intravenous injection of gemcitabine 900 mg m(-2) on days 8 and 15. This treatment was repeated every 4 weeks. A total of 44 patients were enrolled into this trial. The median age of all patients was 74 years, with 23 patients younger than 75 years and 21 patients with 75 years of age or older. A total of 18 patients (41%) achieved a partial response. The median survival time was 13.2 months and the 1-year survival rate was 59%. The most common grade 3-4 toxicity was neutropenia (57%). The frequency of grade 3 nonhaematologic toxicities was less than 5%. In addition, no significant difference in the response, survival or toxicities was observed between the patients younger than and those older than 75 years of age. This combination chemotherapy demonstrated a promising effectiveness and acceptable toxicity in patients with advanced NSCLC, even in patients older than 75 years. .

We describe the first reported case (to our knowledge) of pulmonary granulomatosis caused by aspirated green tea. In this case, we found granulomatous alveolitis with lymph follicles, T lymphocytosis with predominantly CD8+ cells in the bronchoalveolar lavage fluids, positive serum precipitin and proliferative response of peripheral blood lymphocytes to the tea infusion, and efficacy of steroid therapy. These results indicate that the pathogenesis of the disease was due to both humoral and cellular immunities to the aspirated green tea.

PURPOSE: Since leukopenia was one of the dose-limiting toxicities of the combination of irinotecan (CPT-11) and cisplatin in a previous trial, we conducted a phase I trial to investigate whether support with recombinant human granulocyte colony-stimulating factor (rhG-CSF) would permit further intensification of the CPT-11 dose in combination with a fixed cisplatin dose. PATIENTS AND METHODS: Twenty previously untreated patients with stage IIIB or IV non-small-cell lung cancer (NSCLC) were treated with CPT-11 on days 1, 8, and 15 in combination with cisplatin 80 mg/m2 intravenously on day 1. In addition, rhG-CSF (2 micrograms/kg/d) was administered on days 4 to 21, except on the days of CPT-11 treatment. The starting dose of CPT-11 was 70 mg/m2, and the CPT-11 dose was escalated in 10-mg/m2 increments until the maximum-tolerated dose was reached. RESULTS: Diarrhea was the dose-limiting toxicity at 90 mg/m2. Two of six patients experienced either grade 3 or 4 diarrhea or grade 3 leukopenia during the first course of therapy at this dose level. Modest escalation of the CPT-11 dose from 80 to 90 mg/m2 resulted in a marked increase in the plasma concentration of 7-ethyl-10-hydroxycamptothecin (SN-38). Occurrence of diarrhea was well correlated with the peak plasma concentration (Cmax) of SN-38 (P = .035). There were 10 partial responses (50%) among 20 patients. CONCLUSION: The recommended dose for phase II studies is 80 mg/m2 of CPT-11, and 80 mg/m2 of cisplatin plus rhG-CSF. With the use of rhG-CSF, the CPT-11 dose can be increased 33% above that in the original regimen (60 mg/m2 of CPT-11 and 80 mg/m2 of cisplatin).

We have conducted a Phase I trial to determine the maximum tolerated dose of CPT-11 together with a fixed dose of cisplatin in patients with advanced lung cancer, and the dose-limiting toxicities of this combination. Fourteen previously untreated patients with stage IIIB or IV disease were treated with CPT-11 (90-min intravenous infusion on days 1, 8, and 15) plus cisplatin (60 mg m-2, intravenously on day 1). The starting dose of CPT-11 was 60 mg m-2, and diarrhea was the dose-limiting toxicity at the 90 mg m-2 dose level. All three patients (all four cycles) given 90 mg m-2 of CPT-11 experienced grade 3 diarrhea. Hematologic toxicity was relatively mild. Elimination of CPT-11 was biphasic with a mean (+/- s.d.) beta half-life of 11.36 +/- 7.26 h. The mean terminal half-life of the major metabolite (7-ethyl-10-hydroxycamptothecin; SN-38) was 22.13 +/- 13.28 (s.d.) h, and modest escalation of the CPT-11 dose from 80 mg m-2 to 90 mg m-2 resulted in a statistically significant apparent increase in the plasma concentrations of SN-38. There were one complete response (7%) and five partial responses (36%) among the 14 patients for an overall response rate of 43%. The recommended dose for Phase II studies is 80 mg m-2 of CPT-11 and 60 mg m-2 of cisplatin.

The patient was a 57-year-old male with long-standing bronchiectasis who developed severe respiratory failure and died in 1991. Autopsy revealed multiple broncholithiasis in both lungs, but no calcified lymph nodes in the hilar region. Since histological examination of the broncholiths showed only stratified structures but no tissue structure, most likely cause was considered to be calcification of mucus in the bronchi. Analysis of the stone components revealed 78% calcium and 22% protein. This patient represents a case of multiple broncholithiasis caused by mucus retention, which is thought to be very rare.
