PURPOSE To demonstrate the efficacy of docetaxel and cisplatin (DP) chemotherapy with concurrent thoracic radiotherapy (TRT) for patients with locally advanced non-small-cell lung cancer (LA-NSCLC). PATIENTS AND METHODS Patients age 75 years or younger with LA-NSCLC, stratified by performance status, stage, and institution, were randomly assigned to two arms consisting of DP (docetaxel 40 mg/m(2) and cisplatin 40 mg/m(2) on days 1, 8, 29, and 36) or mitomycin, vindesine, and cisplatin (MVP) chemotherapy with concurrent TRT. RESULTS Between July 2000 and July 2005, 200 patients were allocated into either the DP or MVP arm. The survival time at 2 years, a primary end point, was favorable to the DP arm (P = .059 by a stratified log-rank test as a planned analysis and P = .044 by an early-period, weighted log-rank as an unplanned analysis). There was a trend toward improved response rate, 2-year survival rate, median progression-free time, and median survival in the DP arm (78.8%, 60.3%,13.4 months, and 26.8 months, respectively) compared with the MVP arm (70.3%, 48.1%, 10.5 months, and 23.7 months, respectively), which was not statistically significant (P > .05). Grade 3 febrile neutropenia occurred more often in the MVP arm than in the DP arm (39% v 22%, respectively; P = .012), and grade 3 to 4 radiation esophagitis was likely to be more common in the DP arm than in the MVP arm (14% v 6%, P = .056). CONCLUSION DP chemotherapy combined with concurrent TRT is an alternative to MVP chemotherapy for patients with LA-NSCLC.

CONTINUOUS culture of human leukaemic cells is still a difficult task, although several leukaemic cell lines have been derived from patients with acute and chronic myelogenous leukaemia1,2 and acute lymphoblastic leukaemia (ALL) (refs 3–6). We describe here B-cell, T-cell and null-cell leukaemic cell lines newly established from three patients with ALL.

A new translocation between chromsomes 2 and 8 t(2p−; 8q+), was found in fresh lymphoma cells from a Japanese patient with Epstein-Barr virus-carrying Burkitts lymphoma, and in a lymphoma cell line derived from this patient. There was no 14q+ translocation, as has been previously described in African and North American Burkitts lymphomas.

Between 1981 and 1986, a total of 46 patients with small cell lung cancer (SCLC) achieving a complete response by chemotherapy with or without chest irradiation were randomized either to receive prophylactic cranial irradiation (PCI) or not. With a median follow-up time of 8.5 years for both groups, only five of 23 patients (22%) in the PCI group developed brain relapse, while 12 out of 23 (52%) in the no PCI group did so (P < 0.05). The frequency of patients developing a sole brain relapse during their whole clinical course was 4% for the PCI group and 17% for the no PCI group, however, the difference was not statistically significant. Patient survival was better for the PCI group (median survival time of 21 months, and 5-year survival rate of 22%) as compared with the no PCI group (median survival time of 15 months, and 5-year survival rate of 13%), showing a marginal significance (P = 0.097). Late neurologic toxicity was infrequent; only one developed a mild deterioration among seven long-term disease-free survivors in the PCI group. These results appear to warrant further clinical trials to clarify the utility of PCI in patients with SCLC achieving a complete response.

Recent studies have suggested the superiority of concomitant over sequential administration of chemotherapy and radiotherapy. Docetaxel and cisplatin have demonstrated efficacy in advanced non-small-cell lung cancer (NSCLC). This study evaluated the safety, toxicity, and antitumour activity of docetaxel/cisplatin with concurrent thoracic radiotherapy for patients with locally advanced NSCLC. Patients with locally advanced NSCLC (stage IIIA or IIIB), good performance status, age ⩽75 years, and adequate organ function were eligible. Both docetaxel and cisplatin were given on days 1, 8, 29, and 36. Doses of docetaxel/cisplatin (mg m−2) in the phase I study portion were escalated as follows: 20/30, 25/30, 30/30, 30/35, 30/40, 35/40, 40/40, and 45/40. Beginning on day 1 of chemotherapy, thoracic radiotherapy was given at a total dose of 60 Gy with 2 Gy per fraction over 6 weeks. In the phase I portion, the maximum tolerated doses (MTD) among 33 patients were docetaxel 45 mg m−2 and cisplatin 40 mg m−2. The major dose-limiting toxicity (DLT) was radiation oesophagitis. The recommended doses (RDs) for the phase II study were docetaxel 40 mg m−2 and cisplatin 40 mg m−2. A total of 42 patients were entered in the phase II portion. Common toxicities were leukopenia, granulocytopenia, anaemia, and radiation oesophagitis, with frequencies of grade ⩾3 toxicities of 71, 60, 24, and 19%, respectively. Toxicity was significant, but manageable according to the dose and schedule modifications. Dose intensities of docetaxel and cisplatin were 86 and 87%, respectively. Radiotherapy was completed without a delay in 67% of 42 patients. The overall response rate was 79% (95% confidence interval (CI), 66–91%). The median survival time was 23.4+ months with an overall survival rate of 76% at 1 year and 54% at 2 years. In conclusion, chemotherapy with cisplatin plus docetaxel given on days 1, 8, 29, and 36 and concurrent thoracic radiotherapy is efficacious and tolerated in patients with locally advanced NSCLC and should be evaluated in a phase III study.

SummaryA combination chemotherapy of irinotecan (CPT-11) and cisplatin (CDDP) has been reported to be active for lung cancer. In the previous trial, however, diarrhoea and leucopenia became the major obstacle for sufficient dose escalation of CPT-11 to improve the treatment outcome. We conducted a phase I study to investigate whether the fractionated administration of CDDP and CPT-11 at escalated dose was feasible and could improve the treatment outcome. Twenty-four previously untreated patients with unresectable non-small-cell lung cancer (NSCLC) or extensive disease of small-cell lung cancer (SCLC) were eligible. Both CDDP and CPT-11 were given on days 1 and 8, and repeated every 4 weeks. The dose of CDDP was fixed at 60 mg m–2 and given by 1-h infusion before CPT-11 administration. The starting dose of CPT-11 was 40 mg m–2, and the dose was escalated by an increase of 10 mg m–2. The maximally tolerated dose of CPT-11 was determined as 60 mg m–2 because grade 4 haematological or grade 3 or 4 non-haematological toxicities developed in six patients out of 11 patients evaluated. Diarrhoea became a dose-limiting toxicity. The objective response rates were 76% for NSCLC and 100% for SCLC. The recommended dose of CPT-11 and CDDP in a phase II study will be 50 mg m–2 and 60 mg m–2 respectively.

A human lymphoblast cell line, NALL‐1, was established from the peripheral blood of a patient with acute lymphoblastic leukemia (ALL). NALL‐1 cells had neither properties of T and B cells nor Epstein‐Barr virus (EBV). Many characteristics of the NALL‐1 line were distinct from those of numerous EBV‐positive lymphoblastoid cell lines previously reported. NALL‐1 cells are considered to have originated from the donors leukemic cells on the basis of their cytogenetic, morphologic and functional features. The NALL‐1 line is the first human leukemic “null” cell line derived from ALL. The significance of this cell line is discussed.

Long-term cancer survivors risk development of second primary cancers (SPC). Vigilant follow-up may be required. We report outcomes of 92 patients who underwent chemoradiation for unresectable stage III non-small-cell lung cancer, with a median follow-up of 8.9 years. The incidence of SPC was 2.4 per 100 patient-years (95% confidence interval: 1.0–4.9).

A recent meta-analysis and randomized studies have demonstrated that combined chemoradiotherapy is associated with a survival advantage for selected patients with locally advanced unresectable non-small-cell lung cancer (NSCLC). We conducted a phase II study of combined chemoradiotherapy to find a more effective combination of drugs and radiation than those previously reported for such patients. Between January 1994 and November 1996, 50 previously untreated patients with locally advanced unresectable NSCLC (stage IIIA with N2 or IIIB disease) were entered in this study. Patients were required to have Eastern Cooperative Oncology Group performance status ≤ 2, age ≤ 75 years and adequate organ function. Treatment consisted of three cycles of cisplatin (20 mg m−2, days 1–5) and 5-fluorouracil (5-FU) (500 mg m−2, days 1–5) every 4 weeks, and concurrent hyperfractionated thoracic radiation (1.25 Gy twice daily, with a 6-h interfraction interval; total radiation dose, 62.5–70 Gy). Of the 50 patients entered, 37 (74%) responded to this chemoradiotherapy, including two (4%) with complete response. By a median follow-up time of 41.0 months, 35 patiennts had died and 15 were stil alive. The median time to progression for responding patients was 14.1 months (range, 2.6–51.3+ months). The median survival time was 18.7 months, with a survival rate of 66.0% at 1 year, 46.0% at 2 years and 27.6% at 3 years. Survival outcome was strongly affected by the extent of nodal involvement (median survival time, 27.4 months for N0–2 disease (n = 37) vs 10.7 months for N3 disease (n = 13);P = 0.007). The major toxicities of treatment were leukopenia and neutropenia (≥ Grade 3, 58% and 60% respectively). Other toxicities of ≥ Grade 3 included thrombocytopenia (26%), anaemia (26%), nausea/vomiting (16%) and radiation oesophagitis (6%). Treatment-related death occurred for one patient. Our findings suggest that cisplatin and 5-FU in combination with concurrent hyperfractionated thoracic radiation is effective and feasible for the treatment of locally advanced unresectable NSCLC. The short-term survival in this study appeared to be more encouraging than those of similar chemoradiation trials. A randomized trial will be needed to compare the combination of cisplatin and 5-FU with other platinum-based regimens together with concurrent hyperfractionated thoracic radiation. In addition, in future studies, inclusion criteria for N3 disease with or without supraclavicular involvement should be reconsidered to correctly evaluate the effect of combined chemoradiotherapy for locally advanced unresectable NSCLC.

A phase II study of fractionated administration of irinotecan (CPT-11) and cisplatin (CDDP) in patients with non-small-cell lung cancer (NSCLC) was conducted. Between January 1996 and January 1998, 44 previously untreated patients with stage IIIB or IV NSCLC were enrolled. CDDP at a dose of 60 mg m–2 was given first and followed by CPT-11 at a dose of 50 mg m–2. Both drugs were given by 1-hour infusion on days 1 and 8, and repeated every 4 weeks up to 4 cycles. 42 patients were evaluated for response and 44 for survival and toxicity. 20 patients (48%: 95% confidence interval 32–63%) achieved an objective response. The median duration of responses was 8 months, and the median survival time and the 1-year survival rate were 12.5 months and 56.8%, respectively. Major toxicities were neutropenia and diarrhoea. Grade 3 or 4 neutropenia occurred in 70.5% of the patients and one patient died of sepsis. Grade 3 or 4 diarrhoea was experienced in 25.0%, but manageable by conventional therapy. In conclusion, fractionated administration of CPT-11 and CDDP was highly effective for advanced NSCLC with manageable toxicities.
