A study was undertaken to determine the maximum tolerated dose, the dose-limiting toxicities, and the response rate of irinotecan administered weekly with concurrent thoracic radiation therapy in patients with locally advanced non-small-cell lung cancer. In a phase I/II clinical trial, patients with histologically documented, surgically unresectable stage IIIA or IIIB non-small cell lung cancer (NSCLC) were enrolled. Irinotecan was administered as a 90 min intravenous infusion once weekly for 6 weeks. The starting dose was 30 mg m(-2) and dose escalation was done in 15 mg m(-2) increments. Dose-limiting toxicity was defined as grade 3 nonhaematologic toxicity (excluding nausea, vomiting and alopecia) or grade 4 haematologic toxicity according to the WHO criteria. Radiation was delivered to the primary tumour and regional lymph nodes (40 Gy), followed by a boost to the primary tumour (20 Gy). Twenty-seven patients were entered into this study at three irinotecan dose levels (30, 45 and 60 mg m(-2)). Twenty-six eligible patients were evaluated for toxic effects and clinical outcome. Severe oesophagitis, pneumonitis, and diarrhoea occurred at 45 and 60 mg m(-2). Three of the five patients given 60 mg m(-2) developed grade 3 or 4 oesophagitis and pneumonitis. In addition, one patient died of pneumonitis after completing therapy at 45 mg m(-2) in the phase II study. The objective response rate was 76.9% (95% CI, 53.0-88.9%). Oesophagitis, pneumonitis, and diarrhoea are the dose-limiting toxicities of weekly irinotecan combined with thoracic irradiation. The maximum tolerated dose and the dose for the phase II study were 60 and 45 mg m(-2) wk(-1), respectively. This combined therapy for locally advanced non-small cell lung cancer is promising and shows acceptable toxicity.

This review summarizes the results reported in preclinical and clinical trials of three novel anticancer drugs developed and tested in Japan. In phase II trials, Irinotecan, a semisynthetic analog of camptothecin, has yielded response rates exceeding 20% in non-small-cell lung cancer, small-cell lung cancer, breast cancer, gastric cancer, colorectal cancer, ovarian cancer, uterine cervical cancer, and non-Hodgkini's lymphoma. It was modestly active on pancreatic cancer and was not active on acute leukemias. Dose-limiting toxicities were leukopenia and diarrhea, and other major toxicities were nausea, vomiting, and alopecia. Amrubicin, a totally synthetic anthracycline, exhibited both higher efficacy on human tumor xenografts and cardiotoxicity milder than that of doxorubicin in preclinical studies. The dose-limiting toxicity in phase I trials was leukopenia. In phase II trials, amrubicin has shown activity equivalent to that of doxorubicin on non-Hodgkin's lymphoma, response rates exceeding 20% on non-small-cell lung cancer, and a response rate of 78.8% on untreated extensive-stage small-cell lung cancer. S-1 is an oral formulation consisting of ftorafur (an analog of 5-fluorouracil), 5-chloro-2, 4-dehydropyrimidine, which inhibits degradation of 5-fluorouracil, and potassium oxonate, which reduces gastrointestinal toxicity, at a molar ratio of 1:0.4:1. In phase I trials, dose-limiting toxicities (myelosuppression and gastrointestinal toxicities) were judged to be milder than those induced by UFT (ftorafur plus uracil). The response rates obtained in phase II trials were 40-49% on advanced gastric cancer, 35.5% on colorectal cancer, 37.5% on head and neck cancer, and 40.7% on breast cancer.

The intensity of complains, short survival and great number of patients makes many oncologists to apply chemotherapy in advanced non-small cell lung cancer/NSCLC/. The achieved median duration of life after chemotherapy was 6 to 12 month. From the other hand non small cell lung cancer chemotherapy is a big burden even to healthy persons. It can worsen the quality of life. That was the reason we evaluated the quality of life after chemotherapy in advanced non small cell lung cancer patients. Taking into account, that the evaluation of quality of life, used in most diseases is useless in advanced NSCLC patients, for appreciation the quality of life in these cases the lung cancer symptoms scale/LCSS/was adopted. In 110 non small cell lung cancer patients in stage IIIB and IV, who received combined chemotherapy by Le Chevalier/Vindesine, Cisplatin, Cyclophosphamide, Lomustin/or by Rosell/Mitomycin, Cyclophosphamide, Cisplatin/the quality of life was evaluated. In 20-persons control group all patients received the symptomatic treatment. In observed group of 110 patients, tumor regressions after 4 courses of chemotherapy allowed to resect cancer in 14 cases, to apply radiotherapy in 42 and to continue chemiotherapy in 23 persons. In every person from above mentioned group the quality of life was evaluated on the basis of intensity of cancer symptoms, accordingly to LCSS. The intensity of cancer symptoms was compared before and after treatment. There were compared; the innensity of complains, weakness, appetite, malnutrition, and hematological, neurological, performans state as well as respiratory sufficiency, infections, cardiac disorders and pain. Apart it, the side effects of applied therapy were assessed in 5 degree scale. The level of hemoglobin, the number of leucocytes, thrombocytes, bilirubine and transaminases in peripheral blood, hematurie, proteinurie, bleedings, appetite, nausea, vomitings, diarrhea, mucosal lesions, infections, skin lesions, cardiac lesions, neurological lesions, respiratory disorders, allergy, alopecia. It was established that, chemotherapy in the most patients improved the performance status and minimized cancer symptoms especially, after good response to treatment. After anticancer therapy more frequently severe infections and cardiac disorders, independently to results of treatment were seen. In non-responders, the cancer symptoms were intensified by side effects of antineoplastic-therapy. In this group of patients the severe side effects of therapy more frequently were seen.

Cisplatin and irinotecan are reported to act synergistically. The authors have conducted a phase II trial combining cisplatin and irinotecan in patients with refractory lung cancer to evaluate the activity and safety of the regimen. Twenty-one patients, who had not responded to prior platinum-based chemotherapy, were entered into the study. Both cisplatin (30 mg/m2) and irinotecan (60 mg/m2) were administrated on days 1, 8, and 15, and the regimen was repeated every 28 days. There were six partial responses, and the response rate was 29% (95% confidence interval, 11.3%-52.2%). The median survival time of all patients was 32 weeks, and 1-year and 2-year survival rates were 43% and 11%, respectively. Major toxicities were hematologic; leukopenia of grades 3 and 4 developed in 43% patients, anemia developed in 38%, and thrombocytopenia developed in 19%. One notable nonhematologic toxicity was diarrhea; which was grade 3 in 38%. The weekly chemotherapy combining cisplatin and irinotecan was active against lung cancer, which is refractory to platinum-based chemotherapy. However, skips of drug administration or dose reduction were necessary in 76% patients during two courses of planned administration, though the ratio of actual dose to scheduled dose was 81%. Dose modification would be necessary to yield better results by this weekly chemotherapy.

The activity and mild toxicity profile of single-agent gemcitabine therapy in untreated (chemonaive) patients with non-small-cell lung cancer (NSCLC) is well documented. This phase II trial was conducted to determine the objective tumour response rate and toxicity profile of single-agent gemcitabine in pretreated patients with NSCLC. Patients with histological evidence of advanced NCSLC stage IIIB or IV; at least one prior chemotherapy regimen including a platinum or taxane analogue; an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2; clinically measurable disease; adequate bone marrow reserve; and adequate renal function; received 1000 mg m(-2) gemcitabine administered over 30 min on days 1, 8 and 15 of a 28-day cycle defined as 3 weekly treatments followed by 1 week of rest. Twenty-nine patients were evaluated for efficacy and 32 for toxicity. One patient achieved a complete response and five patients had a partial response resulting in a total response rate of 20.6% (95% confidence interval (CI) 6-34). Median response duration was 7 months (range 4-11 months). Twelve (41%) patients reached stable disease after two cycles of therapy and 11 (38%) patients had disease progression. Median progression-free survival time was 3 months and median overall survival time was 5.5 months. Toxicity was generally mild (grades 0-2). Severe (grade 3 or 4) haematological toxicities included grade 3 anaemia in one patient and grade 3 thrombocytopenia in two patients. Severe non-haematological toxicities included one patient each with grade 3 liver transaminase elevations, nausea/vomiting and diarrhoea. This study confirms the activity and safety of single-agent gemcitabine in pretreated patients with advanced NSCLC who are refractory or sensitive to first-line therapy.

Irinotecan (CPT-11) and carboplatin have broad anti-tumor activities. We conducted a Phase I study of CPT-11 combined with carboplatin in previously untreated solid cancers, especially advanced lung cancer. The aim of the study was to determine the maximum tolerated dose (MTD) and the dose-limiting toxicities in this regimen. In addition, we prospectively evaluated the Chatelut formula for predicting carboplatin clearance. Patients with advanced cancer were treated with CPT-11 (days 1, 8, and 15) and carboplatin (day 1) of a fixed-target area under the concentration-time curve (AUC) of 5 mg x min/ml. Carboplatin dose was determined by multiplying the AUC by the clearance predicted using the Chatelut formula. The CPT-11 dose was escalated from 40 mg/m2 to the MTD by 10 mg/m2. A total of 27 patients, 26 lung cancer patients and 1 colon cancer patient, were enrolled in this study. Dose-limiting leukoneutropenia, thrombocytopenia, and diarrhea, including one treatment-related death, were observed at 60 mg/m2 CPT-11, indicating that this level was the MTD. In 11 patients, the actual AUCs of carboplatin almost achieved the target AUC of 5. Fifteen (60%) of 25 evaluable patients showed an objective response, with an 85% response rate [11 of 13 patients (complete response, 31%; partial response, 54%)] in small cell lung cancers and a 36% response rate (4 of 11 patients) in non-small cell lung cancers. Neutropenia, thrombocytopenia, and diarrhea were the dose-limiting toxicities in this regimen. CPT-11 (50 mg/m2) under the carboplatin target AUC of 5 using the Chatelut formula was the recommended dose for further Phase II study, and this regimen seems to be active for small cell lung cancer.

Weekly vinorelbine injection with cisplatin had been used in treatment of non-small-cell lung cancer. We performed a phase II trial to evaluate the efficacy and toxicity of a new schedule of vinorelbine and cisplatin in patients with previously untreated, inoperable (stage IIIB or stage IV) non-small-cell lung cancer. From April 1996 to May 1997, 52 patients were enrolled for study, and 50 patients were eligible and evaluable for both response and toxicity assessment. Therapy consisted of vinorelbine, 30 mg/m2, intravenously on days 1 and 5 of a 21-day cycle, and cisplatin 100 mg/m2 (reduced to 80 mg/m2 after the first seven patients) given on day 1. A total of 211 treatment courses were administered; the median number of cycles administered per patient was 4.5 (range: 1-6), the median dose intensity for vinorelbine was 16.9 mg/m2/week (84.4%), whereas that of cisplatin was 22.8 mg/m2/week (84.7%). Twenty-five patients responded to therapy for an overall response rate of 50%; one patient attained a complete response (2%). The main toxicities were vomiting, myelosuppression, and diarrhea, which included World Health Organization grade 3 or 4 nausea/vomiting (58% patients), anemia (41% patients), neutropenia (12% patients), and diarrhea (14%). The median duration of responses was 9 months. The median time to disease progression was 6.8 months (range 0.4-18.1 months). Median survival was 13 months, and 54% of patients were alive at 1 year. We conclude that this new schedule of vinorelbine and cisplatin achieves a high response with acceptable toxicity profile in patients with advanced non-small-cell lung cancer.

We conducted a randomized phase II trial of two different schedules of topotecan in patients with advanced-stage non small lung cancer (NSCLC) without prior cytotoxic chemotherapy. All patients had histologic or cytologic confirmation of stage IV (M1) or III-B NSCLC. Patients were stratified by performance status, stage and weight loss. Patients were randomized to receive topotecan at intravenous doses of 1.5 mg/m(2)/day over 30 min for 5 days every 3 weeks (Arm A) or 1.3 mg/m(2)grade 3 in both arms included leukopenia, thrombocytopenia, malaise, constipation, diarrhea, lethargy, pulmonary, vomiting, infection and myalgia. Severe (> or = grade 3) thrombocytopenia occurred in 15.8% of Arm A patients and 37.8% of Arm B patients and this difference was statistically significant (P=0.03). The median times to progression are 101 and 63 days (P=0. 75) and the median survival times are 257 and 179 days (P=0.83) for Arms A and B, respectively. These differences in time to progression and overall survival are not statistically significant. Topotecan has limited, single agent activity in advanced NSCLC when given as 1. 5 mg/m(2)/day over 30 min for 5 days every 3 weeks. We do not intend to pursue further investigations with topotecan in patients with NSCLC.

The study compares the cause of death profile in a rural area of South Africa (Agincourt), with that in a rural area of West Africa (Niakhar), and in a developed country with the same life expectancy (France, 1951) in order to determine causes with high and low mortality and priorities for future health interventions. In the two African sites, causes of death were assessed by verbal autopsies, whereas they were derived from regular cause of death registration in France. Age-standardized death rates were used to compare cause-specific mortality in the three studies. Life expectancy in Agincourt was estimated at 66 years, similar to that of France in 1951, and much higher than that of Niakhar. Causes of death with outstandingly high mortality in Agincourt were violent deaths (homicide and suicide), accidents (road traffic accidents and household accidents), certain infectious diseases (HIV/AIDS, tuberculosis, diarrhea and dysentery), certain chronic diseases (cancer of genital organs, liver cirrhosis, gastrointestinal hemorrhage, maternal mortality, epilepsy, acute rheumatic fever, and pneumoconiosis) and malnutrition of young children (kwashiorkor). Causes of death with lower mortality than expected were primarily respiratory diseases (pneumonia, bronchitis, influenza, lung cancer), other cancers, vaccine preventable diseases (measles, whooping cough, tetanus), and marasmus. Verbal autopsies could be used in a rural area of a developing country without formal cause of death registration to identify the most salient health problems of the population, and could be compared with a formal cause of death registration system of a developed country.

A phase I study was designed to evaluate the toxicity of escalating doses of gemcitabine along with fixed-dose paclitaxel in patients heavily pretreated with chemotherapy or radiotherapy. All patients had no prior therapy with the study drugs and possessed both adequate performance and end organ function. Eighteen patients were entered in the study. Characteristics included a median age of 66 years (range, 41 to 77) and stage IV disease in all patients; there were six patients with colon cancer, two with bladder cancer, three with non-small-cell lung cancer, two with esophageal cancer, three with pancreatic cancer, and two with cancer of unknown primary. Paclitaxel (150 mg/m2 over 3 hours) was given on day 1 and gemcitabine (800, 900, and 1,000 mg/m2 over 15 minutes) was given in three separate dose-escalating cohorts (1-3) on days 1 and 8. The treatment cycled every 21 days. The dose-limiting toxicity (DLT) proved to be neutropenia. All nonhematologic toxicities were mild and included gastrointestinal (nausea, vomiting, and diarrhea), dermatologic (rash), and neurologic (paresthesias) disturbances along with transient elevations of liver function tests. The combination of gemcitabine and paclitaxel seems to be well tolerated, and the recommended starting dose for a phase II study, in pretreated patients using a day 1/day 8 treatment schedule, should be 900 mg/m2 for gemcitabine (days 1 and 8) along with 150 mg/m2 for paclitaxel (day 1).
