Abstract
We report on a human small cell lung cancer subline (H69/OA100) resistant to okadaic acid, an inhibitor of protein phosphatases. H69/OA100 showed cross-resistance to cis-diamminedichloroplatinum(II) (CDDP), adriamycin, and vinca alkaloids. Intracellular retention of adriamycin and CDDP in H69/OA100 was the same as those in H69. H69/OA100 was not shown to express MDR-1 by the reverse transcription polymerase chain reaction method. Expression level of mRNA of multidrug resistance-associated protein (MRP) in H69/OA100 was the same as that in H69. These data suggest that the mechanism of drug resistance in H69/OA100 might be due to a new mechanism of non-P-glycoprotein mediated multidrug resistance.

Abstract
To determine a standard combination chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC), we conducted a phase III trial of irinotecan (CPT-11) to test the hypotheses that CPT-11+cisplatin is superior to cisplatin+vindesine and that CPT-11 monotherapy is not inferior to cisplatin+vindesine. A total of 398 patients with previously untreated NSCLC were randomised to receive cisplatin+CPT-11 (CPT-P), cisplatin+vindesine (VDS-P) or CPT-11 alone (CPT). In the CPT-P arm, CPT-11 60 mg m(-2) was administered on days 1, 8 and 15, and cisplatin 80 mg m(-2) was administered on day 1. In the VDS-P arm, cisplatin 80 mg m(-2) was administered on day 1, and vindesine 3 mg m(-2) was administered on days 1, 8 and 15. In the CPT arm, CPT-11 100 mg m(-2) was administered on days 1, 8 and 15. The median survival time was 50.0 weeks for patients on CPT-P, 45.6 weeks for those on VDS-P and 46.0 weeks for those on CPT (P=0.115, CPT-P vs VDS-P; P=0.089, CPT vs VDS-P), and the hazard ratio was 0.85 (95% confidence interval (CI): 0.65-1.11) for CPT-P vs VDS-P and 0.83 (0.64-1.09) for CPT vs VDS-P. The response rate was 43.7% for patients on CPT-P, 31.7% for those on VDS-P and 20.5% for those on CPT. Major adverse reactions were grade 4 neutropenia observed in 37, 54 and 8% of the patients on CPT-P, VDS-P and CPT, respectively; and grades 3 and 4 diarrhoea observed in 12, 3 and 15% of the patients, respectively. CPT-P therapy produces comparable survival to VDS-P in patients with advanced NSCLC. CPT-11 monotherapy is not inferior to VDS-P in terms of survival. The CPT-11-containing regimen is one of the most efficacious and well tolerated in the treatment of advanced NSCLC.

Abstract
The quality of life questionnaire for cancer patients treated with anticancer drugs (QOL-ACD), which consists of four domains (functional, physical, mental, and psychosocial) and a global face scale, was developed as a generic questionnaire for Japanese cancer patients undergoing chemotherapy. We examined the validity and reliability of this questionnaire in Japanese patients with advanced non-small-cell lung cancer (NSCLC), who participated in two randomized phase III trials. After excluding two items, one showing low test-retest reliability and the other showing poor convergent validity for the target population, Cronbach's alpha coefficients ranged from 0.795 to 0.897 and the intra-class correlation coefficients ranged from 0.612 to 0.866. These results confirmed the high reliability of the questionnaire. The results of factor analysis provided strong support for the domain structure used in the questionnaire. Each of the four domains had a moderate to strong association with important clinical variables, such as performance status or weight loss, and correlation analysis showed that the face scale provided an appropriate measure of the global quality of life. These results indicated that the QOL-ACD is potentially useful for clinical research on Japanese patients with advanced NSCLC.

Abstract
BACKGROUND It has been reported that the combination of gemcitabine (LY188011; GEM) and cisplatin (CDDP) in a 4-week schedule showed a high response rate for patients with non-small-cell lung cancer (NSCLC), but GEM could not be administered on day 15 because of increased myelosuppression in many patients. The present study was performed to evaluate the efficacy and safety of GEM and CDDP in a 3-week schedule. METHODS Patients with unresectable NSCLC without prior chemotherapy were enrolled. We administered 1000 mg/m2 of GEM on days 1 and 8, and 80 mg/m2 of CDDP on day 1. The feasibility of the combination therapy was confirmed in 8 patients, and then 20 more patients were enrolled, to evaluate the efficacy and safety of this combination therapy for all 28 patients. RESULTS The response rate was 42.9% (12/28) and the median survival time was 12.6 months. Neutropenia, leukopenia, anemia, thrombocytopenia or lymphocytopenia of grade 3 or higher were observed as hematological toxicity, and anorexia, nausea, fatigue, or vomiting of grade 3 were the nonhematological toxicities, but most of these toxicities were of grade 2 or less. For GEM and CDDP, 89% and 91% of the scheduled doses, respectively, were administered. CONCLUSION This is the first study of the combination of GEM and CDDP with a 3-week schedule in Japan, and the results showed a low level of myelosuppression, high dose intensity, and high response rate, similar to the results reported in other countries. Accordingly, the combination of GEM and CDDP with a 3-week schedule may be a promising regimen for the treatment of NSCLC in Japan.

Abstract
BACKGROUND The efficacy and safety of S-1, a new oral fluoropyrimidine, were evaluated in patients with non-small-cell lung cancer (NSCLC). The objective of this study was to determine whether the drug should be investigated in a late phase II study. METHODS Each treatment course consisted of an oral dose of S-1, 50 mg/body or 75 mg/body, twice a day for 28 days followed by a 2-week washout period. RESULTS Fifty-six eligible patients were enrolled. Five of the 40 previously untreated patients (12.5%; 90% confidence interval, 6.2%-23.5%) showed a partial response (PR), and no tumor response was observed in the 16 previously treated patients. The median survival duration in all eligible patients was 8.4 months, with a 1-year survival rate of 27.3%. The incidences of grade 3 or more severe adverse effects were: anemia, 5.4%; leukopenia, 5.4%; neutropenia, 5.4%; thrombocytopenia, 1.8%; anorexia, 3.6%; diarrhea, 3.6%; and general fatigue, 5.4%. These effects disappeared after cessation of the drug or appropriate treatment. One patient died as a result of aggravated interstitial pneumonitis, but the relationship of this event to S-1 was not clear. CONCLUSION S-1 showed modest activity with mild toxicity in the treatment of non-small-cell lung cancer. Based on this result, we will progress to the next stage of a late phase II study for advanced NSCLC, and a phase II study of S-1 and cisplatin for advanced gastric cancer. Final results will be reported as they are obtained.

Phase II study of S-1, a novel oral fluorouracil, in advanced non-small-cell lung cancer. Br J Cancer 2001; 85:939-43. [PMID: 11592762 PMCID: PMC2375091 DOI: 10.1054/bjoc.2001.2031] [Citation(s) in RCA: 172] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2000] [Revised: 06/21/2001] [Accepted: 07/03/2001] [Indexed: 11/18/2022] Open
Abstract
The purpose of this study was to evaluate the efficacy and safety of a novel oral anticancer fluoropyrimidine derivative, S-1, in patients receiving initial chemotherapy for unresectable, advanced non-small-cell lung cancer (NSCLC). Between June 1996 and July 1998, 62 patients with NSCLC who had not received previous chemotherapy for advanced disease were enrolled in this study. 59 patients (22 stage IIIB and 37 stage IV) were eligible for the evaluation of efficacy and safety. S-1 was administered orally, twice daily, after meals. 3 dosages of S-1 were prescribed according to body surface area (BSA) so that they would be approximately equivalent to 80 mg m(-2)day(-1): BSA < 1.25 m(2), 40 mg b.i.d.; BSA> or =1.25 but <1.5 m(2); 50 mg b.i.d., and BSA> or =1.5 m(2): 60 mg b.i.d. One cycle consisted of consecutive administration of S-1 for 28 days followed by a 2-week rest period, and cycles were repeated up to 4 times. The partial response (PR) rate of the eligible patients was 22.0% (13/59); (95% confidence interval: 12.3-34.7%). A PR was observed in 22.7% (5/22) of the stage IIIB patients and 21.6% (8/37) of the stage IV patients. The median response duration was 3.4 months (1.1-13.7 months or longer). Grade 4 neutropenia was observed in one of the 59 patients (1.7%). The grade 3 or 4 toxicities consisted of decreased haemoglobin level in 1.7% of patients (1/59), neutropenia in 6.8% (4/59), thrombocytopenia in 1.7% (1/59), anorexia in 10.2% (6/59), diarrhoea in 8.5% (5/59), stomatitis in 1.7% (1/59), and malaise in 6.8% (4/59), and their incidences were relatively low. There were no irreversible, severe or unexpected toxicities. The median survival time (MST) of all patients was 10.2 months (95% confidence interval: 7.7-14.5 months), and the one-year survival rate was 41.1%. The MST of the stage IIIB patients was 7.9 months, and that of the stage IV patients was 11.1 months. The one-year survival rates of the stage IIIB and IV patients were 30.7% and 47.4%, respectively. S-1 was considered to be an active single agent against NSCLC. Further study of S-1 with other active agents is warranted.

Abstract
PURPOSE We conducted a phase I trial of docetaxel, a new antimicrotubule agent, combined with irinotecan (CPT-11), a topoisomerase I inhibitor. The aim was to determine the maximum-tolerated dose (MTD) of docetaxel combined with CPT-11, as well as the dose-limiting toxicities (DLTs) of this combination in advanced non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS Thirty-two patients with stage IIIB or IV NSCLC were treated at 4-week intervals with docetaxel (60 minutes, day 2) plus CPT-11 (90 minutes, days 1, 8, and 15). The starting doses of docetaxel/CPT-11 were 30/40 mg/m(2), and doses were escalated in 10-mg/m(2) increments until the MTD was reached. RESULTS The MTD of docetaxel/CPT-11 was 50/60 mg/m(2) (level 5A), or 60/50 mg/m(2) (level 5B). Neutropenia and diarrhea were the DLTs. CPT-11 did not affect the pharmacokinetics of docetaxel. There were 11 (37%) partial responses among 30 patients. The median survival time was 48 weeks, and the 1-year survival rate was 44.9%. CONCLUSION The combination of docetaxel and CPT-11 seems to be active against NSCLC, with acceptable toxicity. The recommended dose for phase II studies is 50 mg/m(2) of CPT-11 (days 1, 8, and 15) and 50 mg/m(2) of docetaxel (day 2) administered every 28 days.

Abstract
Based upon the results of phase I study of irinotecan (CPT-11) combined with cisplatin (CDDP) on non-small cell lung cancer (NSCLC), a combination phase II study on NSCLC was carried out from Feb., 1992 to Sep., 1992. CPT-11 (60 mg/m2) and CDDP (80 mg/m2) were administered by i.v. drip infusion, with administration schedules of Days 1, 8, 15 and only Day 1, respectively. This therapy course was repeated every 4 weeks. Subjects were NSCLC patients of stage III B or IV disease. Those without prior chemotherapy (Group A) and those with prior therapy (Group B) were enrolled separately. Seventy patients were entered into Group A and 32 patients into Group B. One of the patients of Group A was ineligible. The characteristics of the eligible cases of Group A were: male/female, 51/18; median age, 61 years old; PS 0/1/2, 18/39/12; stage IIIB/IV, 26/43; and adeno/squamous/large, 51/15/3. Those of group B were: male/female, 20/12; median age, 62 years old; PS 0/1/2, 5/18/9; stage I/IIIB/IV, 1/7/24, adeno/squamous/large/ad-sq, 28/2/1/1. Thirty-three patients (47.8%) responded in Group A and B patients (25.0%) responded in Group B. Major adverse reactions (grade 3 or higher) of Group A/Group B were neutropenia (80.3%/73.3%), anemia (35.3%/34.4%), diarrhea (18.8%/28.1%) and nausea/vomiting (34.8%/34.4%). Median survival times for Group A and Group B were 308 and 295 days, respectively. CPT-11 in combination with CDDP is effective against NSCLC, suggesting that further studies are needed to determine the usefulness of this therapy.

Abstract
BACKGROUND Combination chemotherapy comprised of oral UFT (a combination of tegafur and uracil) and cisplatin was shown to be an effective regimen for the treatment of advanced nonsmall cell lung carcinoma and to be associated with a low incidence rate of toxicity in a previous, single institution, Phase II trial on a small patient sample. Therefore, the current multiinstitutional Phase II trial was conducted to confirm the earlier results. METHODS Eligible patients had histologically or cytologically confirmed Stage IIIB or IV nonsmall cell lung carcinoma and good performance status. Patients who had received prior treatment were excluded. All had measurable disease. UFT (400 mg/m(2)) was administered orally on Days 1-14, and cisplatin (80 mg/m(2)) was injected intravenously on Day 8. Treatment was repeated every 3-4 weeks. RESULTS Approximately 70% of the 108 eligible patients had systemic metastatic disease. All 108 patients were assessable for toxicity and survival, and 103 were assessable for response. Among these 103 patients there was 1 complete response and 29 partial responses, for an overall response rate of 29.1% (95% confidence limits [CL], 20.4-37.9%). The median survival time was 40 weeks and the 1-year survival rate was 39% (95% CL, 30-49%). The median progression free survival time was 28 weeks. Eastern Cooperative Oncology Group Grade 3 leukopenia and thrombocytopenia were observed in only 1 patient (0.9%) and 3 patients (2.8%), respectively. Grade 3/4 nonhematologic toxicities included elevated bilirubin (6.5%) and emesis (7.4%). One patient who had a past history of duodenal ulcer died of ulcer perforation 15 days after completing the first treatment cycle. CONCLUSIONS Oral UFT plus cisplatin is a moderately active regimen with an extremely low rate of incidence of myelosuppression as an adverse event, and warrants comparison with other cisplatin-based regimens in a prospective randomized trial.

Abstract
Navelbine is a derivative of vinca alkaloid that interferes with tubulin assembly and exhibits antitumor activity. Clinical trials with single-agent Navelbine proved it to be effective against non-small cell lung cancer (NSCLC), breast cancer, and other tumors. At present, clinical trials by combination with various drugs are ongoing NSCLC and breast cancer. Navelbine+cisplatin is considered to be a standard therapy for NSCLC in Europe and SWOG. In breast cancer, the combination chemotherapy of Navelbine with anthracyclines, 5-FU, and other agents has been reported to be effective. The main adverse reactions caused by Navelbine are leukopenia and neutropenia. It causes less nerve neuropathy than vindesine. As Navelbine is a central therapeutic drug in combination therapy for NSCLC, more effective combination therapy with it are expected to be developed.

Abstract
The role of tropisetron as an anti-emetic drug in the prevention of delayed nausea and vomiting remains unclear. Therefore, effectiveness of tropisetron in patients receiving cancer chemotherapy was evaluated by application of summary measures using a quality of life (QOL) questionnaire. The diary-type QOL self-rating questionnaire was constituted by seven scales. A double-blind randomized, multicentre study was performed in 33 hospitals. Quality of life was measured in 98 patients. Patients receiving cisplatin were randomized to group T (administration of tropisetron before and 4 days after cisplatin treatment) and group P (administration of tropisetron before cisplatin treatment and followed by placebo for 4 days). The rate of complete protection from delayed emesis in the groups T and P was 46.3 and 36.5%. All scales, except social wellbeing changed immediately in both groups and reached a nadir on days 2-3, after that returning to the control levels during 2 weeks after cisplatin treatment. Group T was significantly better than group P in physical wellbeing, mental wellbeing, functional wellbeing and global QOL scores summarized by area under the curve and Difmax (maximum differences of QOL scales' score from the best score throughout the entire period). These results indicate that continuous administration of tropisetron could contribute to preventing patient QOL influenced by cisplatin treatment, and the combined use of summary measures may be useful for the evaluation of QOL in cancer clinical trial.

Abstract
The combination Phase I study of gemcitabine hydrochloride with cisplatin was conducted in the patients with non-small cell lung cancer (NSCLC) at 5 investigation sites. Gemcitabine was administrated on day 1, 8 and 15 and cisplatin on day 1 of each 28-day cycle. The dosage of cisplatin was fixed to 80 mg/m2 and the dosage of Gemcitabine was gradually escalated in 3 dosing level from 600, 800 to 1,000 mg/m2. The maximum tolerated dose (MTD) and the recommended dose was determined with Continual Reassessment Method. For each dose level, 6 cases, 3 cases and 6 cases were registered respectively and all 15 cases were evaluable. In the dose level 3 with 1,000 mg/m2 of gemcitabine and 80 mg/m2 of cisplatin, grade 4 neutropenia was observed as DLT in 3 out of 6 cases, thus dose level 3 was considered as MTD and the recommended dose. Major adverse events were leukopenia, neutropenia, nausea/vomiting and anorexia. The incidence of such adverse events seemed to be dose-dependent and especially the grade of neutropenia seemed to be more serious as the dose increased. Also, the grade of liver function tests abnormal seemed to be more serious as the dose increased but the incidence as well as the grade did not have tendency of dose-dependent in another events including renal function tests abnormal. On the other hand, as to the efficacy PR was observed in 4 out of 15 cases. Based upon the results, it is necessary to discuss further the efficacy in the recommended dose in the combination therapy of gemcitabine and cisplatin.

Abstract
Through the 1980's and the early part of the 1990's several new anti-cancer drugs to fight lung cancer were clinically introduced, bringing cytotoxic chemotherapy to play an important role as a mainstay in the combined modality therapy for both small cell and non-small cell lung cancer. This is different from the state prior to the introduction of these drugs. There is no need to say that these advances were supported by the unceasing efforts of oncologists and their patience in performing the many randomized controlled trials. This review attempts to summarize the history of the clinical developments in lung cancer treatment since the beginning of the 20th century.

Abstract
We conducted multi-site early phase II trial or oral etoposide administered for 21 consecutive days in patients with cervical or ovarian cancer in cooperation with 19 institutes. Fifty mg/body of oral etoposide was administered daily for 21 consecutive days. Cycles were repeated every 28 days. In cervical cancer, 24 patients were enrolled and 17 of them were evaluated. The overall response rate including CR and PR was 23.5% (4/17). In ovarian cancer, 18 patients out of 21 enrolled were evaluated. The overall response rate was 16.7% (3/18). The primary toxicity observed was myelosuppression such as leukopenia, neutropenia, hemoglobin decrease and thrombocytopenia. Other adverse effects were anorexia, nausea, vomitting, fatigue, alopecia and stomatitis. From these results we concluded that oral etoposide administered for 21 consecutive days was effective against cervical cancer.

A multicenter cooperative phase I study of ZD-1694 (raltitrexed), a novel, folate-based thymidylate synthase (TS) inhibitor, was conducted with single and repeated doses in 30 patients with various malignant tumors. ZD-1694 was intravenously infused over 15 minutes. In the single-dose study, the initial dose was fixed at 1.0 mg/m2 (1n), and the dose was escalated stepwise up to 3.5 mg/m2 (3.5 n). Based on the results of the single-dose study, in the repeated-dose study, doses of 2.5 n and 3 n were infused every three weeks (3 weeks/one course). In principle, patients received 2 courses or more. Of the 29 eligible patients, 16 were in the single-dose study and 13 in the repeated-dose study. Adverse reactions were evaluated in all eligible patients. In the single-dose study, neutropenia, nausea/vomiting, diarrhea, and transaminase (GOT, GPT) increases, of grade 3 or higher, occurred at high doses of 3 n and 3.5 n. These were regarded as dose-limiting toxicities (DLT). DLT of grade 3 or higher were observed in 1 of 4 patients given 3 n and 2 of 4 patients given 3.5 n. These results suggested that the maximum tolerated dose (MTD) of ZD-1694 was 3.5 n (3.5 mg/m2). In the repeated-dose study, DLT of grade 3 or higher was observed in no more than one third of each dose group, 2 of the 6 patients given 2.5 n and 2 of the 7 patients given 3 n. These results suggested that 3 n (3.0 mg/m2), a dose nearer to MTD, was the recommended dose for the phase II study. Although transaminase increases were observed in all patients, in 12 of them the increase was grade 2 or lower and reversible. A pharmacokinetic investigation showed the mean elimination half life of ZD-1694 plasma concentration was 91.5 hours in the single-dose group and 119.1 hours in the repeated dose group. It was suggested that ZD-1694 is metabolized to polyglutamates after uptake and retained in the cells for a long duration. However, no accumulation was seen in plasma concentration of ZD-1694 following repeated doses at 3-weekly intervals. One PR was observed in a patient with colorectal cancer receiving 2.5 n in the repeated-dose study. Based on these results, the recommended dosage and administration for the phase II study of ZD-1694 was 3 n (3.0 mg/m2) intravenously infused over 15 minutes every 3 weeks.

Abstract
Oxaliplatin is a new platinum derivative. A multicentric phase I study was conducted with a monotherapy of Oxaliplatin. A total of 20 patients were enrolled who had histologically proven 6 ovarian cancers, 5 uterine cervix cancers, 3 lung cancers, 3 breast cancers, 1 endometrial cancer, 1 gastric cancer, and 1 colorectal cancer. Oxaliplatin was administered as a 2-hour infusion at doses of 20, 40, 80, 130, and 180 mg/m2 every 3 weeks, for a total of 30 cycles. A dose-related and reversible peripheral sensory neuropathy was the dose-limiting toxicity with minimal hematotoxicity and no nephrotoxicity. No hydration was needed. The plasma platinum concentration was biphasically decreased. Cmax and AUC were dose-dependent. T1/2 beta was 31.3 hours. The recommended dose for further studies was 130 mg/m2. A partial response was observed in endometrial cancer.

Abstract
E7010 is a novel sulfonamide which was discovered using slow-growing colon 38 carcinoma cells as a screening model. E7010 exhibits a broad spectrum of antitumor activity against human tumor xenografts. The mechanism of action is by arresting the progression of cells in M phase of the cell cycle by inhibiting tubulin polymerization. The objective of this phase I study was to determine the maximum allowable dose (MAD), toxicity, and pharmacokinetics of single or 5-day repeated doses of E7010. In the single-dose study, E7010 was administered orally to 16 patients at doses ranging from 80 to 480 mg/m2. The dose-limiting toxicity was peripheral neuropathy at a dose of 480 mg/m2. Hematological and gastrointestinal toxicities were mild. In the 5-day repeated-dose study, 41 patients were given E7010 at doses ranging from 30 to 240 mg/m2 per day. The dose-limiting toxicities were peripheral neuropathy and intestinal paralysis. Gastrointestinal toxicity was dose-dependent but not severe. Hematological toxicity was not dose-dependent. Pharmacokinetic analysis in the single-dose study showed a rapid increase in the plasma levels of the drug after administration, followed by disappearance with a t1/2 of 4.4-16.6 h. The variation in area under the plasma concentration-time curve (AUC) between the patients was small and increased in a dose-dependent manner. Total drug recovery in urine 72 h after administration was 77.8+/-11.4%, indicating that E7010 has favorable absorption and elimination profiles. The changes in the plasma levels of E7010 on day 5 in the 5-day repeated-dose study were almost the same as those on day 1, indicating that the drug did not accumulate. In the single-dose study, spinal cord metastasis exhibited a 74% reduction in a patient with uterine sarcoma and a minor response (MR) was observed in a pulmonary adenocarcinoma patient. In the 5-day repeated-dose study decreases in the tumor markers carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC) were observed in a patient with stomach cancer and in a patient with recurrent uterine cervical carcinoma, respectively. The recommended phase II doses are 320 mg/m2 for a single-dose study and 200 mg/m2 per day for a 5-day repeated-dose study. Since the activity of E7010 is time-dependent, i.e. a certain concentration of E7010 is required for more than 12 h to suppress the growth of P388 leukemia cells, it is recommended that subsequent phase I/II studies be conducted using a divided dose schedule in order to maintain the blood level of E7010.

Abstract
A phase I trial of the combination of irinotecan (CPT-11) with cisplatin in advanced non-small cell lung cancer (NSCLC) showed a very promising response rate of 54% in previously untreated NSCLC patients. This study was conducted to confirm the activity and toxicities of CPT-11 and cisplatin combination for previously untreated NSCLC in a multi-institutional phase II study. Seventy patients with stage IIIB or IV NSCLC received CPT-11 60 mg m(-2) intravenously (i.v.) on days 1, 8 and 15, and cisplatin 80 mg m(-2) (i.v.) on day 1 every 4 weeks. Assessments were made of response, survival and toxicities. Sixty-nine were eligible, and evaluable for toxicities and survival, and 64 patients evaluable for response. Thirty-three patients (52%; 95% confidence interval 39-64%) achieved an objective response, with one complete response (2%) and 32 partial responses (50%). The median duration of response was 19 weeks and the overall median survival time was 44 weeks. The 1-year survival rate was 33%. The major toxic effects were leucopenia and diarrhoea. Grade 3 or 4 leucopenia, neutropenia, and diarrhoea occurred in 32 patients (46%), 53 patients (80%), and 13 patients (19%) respectively. A combination of CPT-11 and cisplatin is very effective against non-small-cell lung cancer with acceptable toxicities.

Abstract
A Phase I study of UFT plus l-LV was conducted in 29 patients (pts) with G.I. cancer on a multicenter cooperative study. UFT and l-LV were given orally in two divided doses for 28 consecutive days, followed by a 14 day-rest period. UFT was fixed in three doses, 250, 313 and 375 mg/m2/day, and l-LV was increased in dose from 25 to 50 and to 100 mg/body/days. Dose-limiting toxicities were anorexia, diarrhea, and nausea/vomiting. The maximum tolerated dose of UFT was 375 mg/m2/day, and l-LV 25 mg/body/day. Severe myelotoxicity was not observed. There were three responders (PR) out of 21 pts with measurable disease at UFT doses of 313 mg/m2/day and l-LV 50 and 100 mg/body/day. Responses observed were abdominal mass (rectal ca), liver metastasis (pancreas ca) and metastasis of liver and lymph-node (gastric ca). As a result of pharmacokinetics, plasma concentrations of 5-methyl-THF were maintained > 1.0 microM for over 5 hours that was considered to have a modulating effect on the plasma concentration. In doses of 50 mg and 100 mg/body/day of l-LV. No accumulations in plasma were observed in patient treated in 28 days by l-LV/UFT therapy. It was suggested UFT and l-LV did not interfere with each other's absorption. A Phase II study is recommended, with doses of 313 mg/m2/day of UFT and 50 or 100 mg/body/day of l-LV.

Abstract
PURPOSE This phase II study was conducted to determine the response and toxicity of gemcitabine (2',2'-difluorodeoxycytidine) in chemotherapy-naive patients with non-small-cell lung cancer (NSCLC). METHODS A group of 73 patients were entered into the study. The patients had received no previous chemotherapy and all had measurable disease. The initial starting dose of gemcitabine was 1000 mg/m2 per week x 3 followed by a week of rest, and was escalated for the next cycle to 1250 mg/m2, provided there were no signs of hematologic toxicity (WBC < 3000/microl and/or platelets < 70,000/microl) in the previous cycle. RESULTS Among 73 eligible patients, there were 19 partial responses (PRs), with an overall response rate of 26.0% (95% confidence interval 16.5-37.6%). The response rate for stage IIIa and IIIb disease was significantly higher than that for stage IV disease [41.4% (12/29) vs 15.9% (7/44); P = 0.028]. The median duration of response in patients showing a PR was 4.6 months (1.7 10.4 months). The median number of cycles given was two per patient (range one to seven). Grade 3 anemia, leukopenia and neutropenia occurred in 15 patients (20.5%), 7 patients (9.6%) and 20 patients (27.4%), respectively. Grade 3 thrombocytopenia occurred in one patient (1.4%) which was not associated with any bleeding. There was no evidence of cumulative toxicity in the later courses of gemcitabine treatment with regard to leukopenia and thrombocytopenia. Other toxicities, including hepatic toxicity, fatigue, nausea/vomiting and fever were mild (grade 2 or less) and transient. One patient was withdrawn from the trial because of a rash. Pulmonary toxicity was experienced in two patients and one patient died of respiratory insufficiency which was thought to be drug-related. CONCLUSIONS Gemcitabine as a single agent has proven to be an active drug for NSCLC with a favorable, generally mild side-effect profile. Further trials in combination with other agents for this disease are currently underway.

Abstract
UNLABELLED MR-20 was administered to 140 lung cancer patients who presented with nephrotoxicity due to cisplatin (CDDP) treatment at 59 institutions throughout Japan during the period from September 1992 through March 1994 to study its suppressive effect on the nephrotoxicity as well as its safety. The results are reported in this paper. METHODS The efficacy and usefulness of MR-20 were studied in a placebo-controlled, double-blind manner. An efficacy rate of 58.7% was achieved in the MR-20 group, and 36.8% in the placebo group: MR-20 was significantly more effective for nephrotoxicity than placebo (U-test). Serum Cr, Ccr and FENa were prevented from significant variations in the MR-20 group, compared with the control group. It was considered that MR-20 is a safe drug, and that it is useful in suppressing the nephrotoxicity of CDDP treatment.

Abstract
We have conducted Phase I study of a novel oral antitumor agent of fluorinated pyrimidines, S-1, in which tegafur (FT) is combined with two classes of modulator, 5-chloro-2,4-dihydroxypyridine (CDHP) and potassium oxonate (Oxo) at a molar ratio of FT:CDHP:Oxo = 1:0.4:1 as a multi-center study with 16 institutions nationwide. Two administration methods, once and twice daily administrations, were evaluated. As a result, MAD was determined as 150 mg/body/day approximately 200 mg/body/day and 75 mg/body x2/day approximately 100 mg/body x2/day, respectively. DLF was myelosuppression, mainly consisting of leukopenia in the two administrations. Most adverse reactions observed, including myelosuppression, disappeared by discontinuation of administration, and recovery was in about 2 weeks. Adverse reactions other than myelosuppression which induced the discontinuation were rash and vomiting. Other adverse reactions observed were anorexia, malaise, diarrhea and stomatitis. Diarrhea and stomatitis were mild (Grade 1), except those observed at a dose of 200 mg/body/day, and did not induce discontinuation of administration. Based on these findings and pharmacokinetic evaluation, the recommended dose and administration for Early Phase II studies were determined as twice daily administration of 75 mg/body for 28 consecutive days with 14 days rest (1 course).

Abstract
A single-institution phase II study indicated that combination chemotherapy using UFT (tegafur and uracil) plus cisplatin (Platinol) in patients with non-small-cell lung cancer was active with less host toxicity than other cisplatin-based therapies. To confirm these observations, the Japan JFT Lung Cancer Study Group conducted a multi-institutional phase II trial. The number of patients planned for this trial is 110. Eligibility includes previously untreated stage IIIB or IV non-small-cell lung cancer and a good performance status. UFT 400 mg/m2 in two divided doses is administered orally on days 1 through 14, and cisplatin 80 mg/m2 is injected IV on day 8. This treatment is repeated every 3 or 4 weeks. Between April 1995 and May 1996, 67 patients were enrolled, and all 67 were considered eligible for an interim analysis performed in October 1996. Among 63 patients evaluable for response, there was an overall response rate of 30% (95% confidence interval, 19% to 41%), with one complete response and 18 partial responses. With a median follow-up duration of 44 weeks, the median survival time was 32 weeks and the 1-year survival rate was 25%. Grade 3 leukopenia occurred in only 1 of 67 patients (1.5%), and there was no thrombocytopenia of grade 3 or greater. Vomiting, the most common nonhematologic toxicity observed, reached grade 3 or 4 in only 6 patients (9%). This interim analysis seems to support the observations of the previous single-institution phase II trial.

Abstract
An early Phase II study with TUT-7 (menogaril), a new anthracycline antitumor antibiotic, was conducted in patients with various malignant tumors at 81 departments of 65 institutions nationwide. One course of TUT-7 treatment consisted of seven (7) or fourteen (14) consecutive days of administration at 75 or 100 mg/body/day with two-week drug withdrawal; at least two courses of treatment were given in principle. Among the 165 patients registered, 145 patients were eligible and 128 patients were evaluable for antitumor efficacy. In 11 patients with malignant lymphoma, one (1) had CR and five (5) had PR (54.5%); in three (3) patients with prostate cancer, one (1) had PR (33.3%); and in 12 patients with uterine cervical cancer, two (2) had PR (16.7%). Adverse drug reactions frequently observed were digestive organ disorders (anorexia and nausea/vomiting) and malaise. The abnormality in laboratory tests observed frequently was myelosuppression (leukopenia and neutropenia).

Abstract
Gemcitabine is a novel nucleoside analog with unique activity against a wide range of solid tumors. We initiated a multicenter phase II study in patients with non-small cell lung cancer (NSCLC) to evaluate the efficacy and safety of gemcitabine. Eligible patients had stage III and IV, previously untreated with chemotherapy, age range from 18 to 80 years, and ECOG performance status 0 2. Gemcitabine was administered at 1000 mg/m2 as a continuous i.v. infusion once a week for a consecutive 3 week period, followed by 1 week of rest. Of the 69 patients enrolled, 67 patients were eligible for efficacy evaluation. The overall response rate was 20.9% with a 95% confidence interval of 11.9-32.6%. The median survival time was 9.0 months and the 12 month survival rate was 31.3%. Grade 3 or 4 toxicities included neutropenia in 22.7%, anemia in 13.4%, leukopenia in 10.4%, anorexia in 10.4%, malaise in 7.5% and nausea/vomiting in 6.0%. Serious toxicities were septic shock and interstitial pneumonia (one patient each). Gemcitabine, administered weekly for three consecutive weeks followed by 1 week of rest, is an active agent for NSCLC. Gemcitabine is currently being evaluated in combination with cisplatin and other agents.

Abstract
A phase I study with TUT-7, a new anthracycline antitumor antibiotic, was conducted in 35 malignant tumor patients at 11 institutions nationwide. The study was initiated with a single dose at 100 mg/body which was equivalent to 2n, then the dose as escalated up to 700 mg/body in accordance with the modified Fibonacci's scheme. The dose limiting factor (DLF) was considered to be leukopenia, and maximum tolerated dose (MTD) was 700 mg/ body. The consecutive days dosing study subsequently conducted started with 25 mg/body/day, and the dose level was escalated up to 150 mg /body/day. TUT-7 was orally administered for seven (7) to fourteen (14) consecutive days in principle. It was considered that DLF was leukopenia and MTD was 100 mg/body/day for consecutive days dosing. The study indicated that serum drug concentrations reached their plateaus on the 5th day after initiation of TUT-7 treatment and the accumulation of this compound was low. With these findings, a regimen with a dose of 100 mg/body/day orally administered for 14 consecutive days was recommended for early phase II studies.

Abstract
To determine the activity and toxicity of gemcitabine (2',2'-difluorodeoxycytidine), three phase II single-agent studies have been conducted in patients with non-small cell lung cancer in Japan. In an early phase II study, 17 previously treated and 47 untreated patients were treated with gemcitabine. Gemcitabine was given intravenously at a dose of 800 mg/m2 or 1,000 mg/m2 once a week for 3 weeks followed by a week of rest, repeating every 4 weeks. Although none of the patients with prior therapy responded, eight (17%) of 47 previously untreated patients showed a partial response. Toxicities of grade 3 or greater included leukopenia (12.5%), thrombocytopenia (6.3%), and anemia (15.6%). We entered 73 patients (group A) and 67 patients (group B) into two late phase II studies. All patients had no previous chemotherapy and had measurable disease. Gemcitabine was administered at a starting dose of 1,000 mg/m2/wk for 3 weeks followed by a week of rest. The dose was escalated to 1,250 mg/m2 if severe toxicity was not seen in the previous course. Nineteen of 73 patients (26%) had a partial response (95% confidence interval, 16.5% to 37.6%) in group A. Of 67 patients, 14 (20.9%) showed a partial response (95% confidence interval, 11.9% to 32.6%) in group B. Grade 3 or greater anemia and leukopenia occurred, respectively, in 15 (20.5%) and seven (9.6%) patients in group A and in nine (13.4%) and seven (10.4%) patients in group B. Grade 3 thrombocytopenia was observed in one patient (1.4%). Other toxicities including hepatic toxicity, fatigue, nausea/vomiting, and fever were mild and transient. Pulmonary toxicity was observed in five patients, two of whom died of respiratory insufficiency. The median durations of response were 19.6 weeks in group A and 20 weeks in group B, and median survival times were 44 and 39 weeks, respectively. In conclusion, gemcitabine is an active agent against non-small cell lung cancer with very mild toxicities. These results suggest that gemcitabine has potential utility on an outpatient basis. Further trials in combination with other active agents are warranted.

Abstract
A 56-year-old woman was admitted to the hospital because of dry coughing and shortness of breath on exertion. In addition, dry eyes and cornea guttata suggested Sjögren's syndrome. Chest radiography revealed linear, reticular shadows throughout the lung fields, and enlargement of hilar and mediastinal lymph nodes. A specimen was obtained by transbronchial lung biopsy but the findings were not condusive; open-lung biopsy was done. The histopathological findings suggested lymphocytic meterstitial pneumonia. Results of genetic analysis and of immuno-histochemical examination conformed that the proliferating lymphocytes were polyclonal. Corticosteroids and immunosuppressive drugs have been used to treat lymphocytic interstitial pneumonia, and they were effective in this case.

Abstract
A late phase II study of LY188011 (gemcitabine hydrochloride), a new synthetic anticancer agent, was conducted at 20 Japanese institutions to evaluate the efficacy and safety of the agent administered alone in patients previously untreated with chemotherapy for primary non-small-cell lung cancer (NSCLC). All of the total 73 patients enrolled were eligible and 69 completed at least one course of LY188011 therapy. All patients were evaluated for safety. The response rate was 26.0% (19/73) of eligible patients. The most common adverse reactions included decreased hemoglobin, leukopenia, neutropenia, anorexia, nausea/vomiting, and malaise. Most adverse reactions were of grade 1 or 2 and only a few grade 3 or 4 reactions were reported. However, since a death occurred due to interstitial pneumonia, careful observation for this event is needed. Based on these results, it may be concluded that LY188011, a new anticancer agent, has adequate efficacy for the treatment of NSCLC and causes few clinically relevant adverse reactions.

Abstract
Phase I study on antimetabolic carcinostatic DMDC was conducted at 16 medical institutions nationwide for patients with various types of malignant tumors. DMDC was administered by intravenous infusion as per the following three schedules: single administration, single repeated administration, and 5-consecutive-day administration. The safety of the compound was examined single administration in 16 patients, by the single repeated administration in 5 patients, and by the 5 consecutive-day administration in 7 patients, for a total of 28 patients. In the single administration trial, 200 mg/m2 (1 n) was given as an initial dose, then increased stepwise to 450 mg/m2 (2.25 n). The single repeated administration trial was conducted at a single dose of 300 mg/m2. One treatment course lasts until recovery from side effects and abnormalities in laboratory test values. As a general rule, the administration was repeated for 2 treatment courses or more. In the 5-consecutive-day administration trial, an initial dose was 30 mg/m2/day (1 n), and increased to 40 mg/m2/day (1.3 n). The dose-limiting factors for both the single and 5-consecutive-day administration trials were decreases in the numbers of leukocytes and neutrophils. The maximum tolerated dose for single administration trial was over 400 mg/m2 (2 n), and for the 5-consecutive-day administration trial 40 mg/m2 (1.3 n). The decrease in the number of leukocytes and neutrophils for both the single administration and 5-consecutive-day administration trial reached its nadir one to two weeks after administration, and recovered in about one week. In the single repeated administration trial, the administration interval for patients who had completed 2 courses was 2 approximately 3 weeks. The plasma half-life of DMDC in the final phase of elimination in the single administration trial was 5.2 approximately 6.3 hours, and no differences were seen among dose levels. The urinary excretion rate was between 32.0 approximately 61.5% until 48 hours after administration. No accumulation was seen in the 5-consecutive-day administration trial. There were no findings to suggest an antitumor effect in the present study. Given the recovery pattern for suppression of marrow, the above mentioned results led us to decide that an recommended method of administration and dosage in an early phase II trial would be 300 mg/m2 per administration by an intravenous infusion every 2 approximately 3 weeks.

Abstract
An early phase II cooperative study of Gemcitabine Hydrochloride (abbreviated to "gemcitabine" herewith) was conducted in patients with a variety of solid tumors (i.e., lung cancer, gastric cancer, pancreatic cancer, colon/rectum cancer, cervical cancer, ovarian cancer and breast cancer) at 56 institutions. The aim of the first step (Step I) was to investigate the feasibility of gemcitabine in a variety of different solid tumors, including lung cancer regarding efficacy and safety. The aim of the second step (Step II) was as a result of step I (Responses were observed) to continue to investigate the efficacy and safety of gemcitabine in chemonaive patients with non-small cell lung cancer. As a Step I study, gemcitabine was administered once weekly at a dose of 800 mg/m2 for a consecutive 3-week period followed by a week of rest, in multiple courses. Among the 29 eligible patients with lung cancer, partial response (PR) was achieved in 3 patients (25.0%, 95% confidence interval: 5.5-57.2%) out of 12 chemonaive patients. Adverse reactions (grade 3 or higher) seen in 29 patients with lung cancer were neutropenia (27.6%), leukopenia (13.8%), decreased hemoglobin (13.8%), thrombocytopenia (10.3%), malaise (6.9%), anorexia (3.4%), nausea/vomiting (3.4%), diarrhea (3.4%), dyspnea (3.4%) and interstitial pneumonia (3.4%). In other types of solid tumors, PR was achieved in 2 (8.7%) out of 23 eligible patients with cervical cancer and in 1 (5.3%) of 19 eligible patients with ovarian cancer, while the use of analgesics became unnecessary in 1 patient with pancreatic cancer. Incidence as well as severity of main adverse reactions in these patients were comparable to those seen in patients with lung cancer. A Step II study, in which gemcitabine was administered once weekly at a dose of 1,000 mg/m2 to chemonaive patients with non-small cell lung cancer, was conducted, referring to the results of Step I and clinical studies conducted overseas. The results of the Step II study demonstrated PR in 5 (14.3%, 95% confidence interval: 4.8 - 30.3%) out of 35 eligible patients with non-small cell lung cancer and that the main adverse reactions were comparable to those seen in the Step I study, posing no tolerability problems in particular.

Abstract
PURPOSE We compared the activity of vinorelbine (VRB) and vindesine (VDS) in a randomized crossover study in patients with previously untreated stages IIIB or IV non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Two hundred four patients were assessable for response and toxicity. VRB was administered at a dose of 25 mg/m2 weekly and VDS at a dose of 3 mg/m2 weekly. Patients who failed to respond after 4 cycles of initial monotherapy were switched to a combination chemotherapy (VRB-->VDS + cisplatin (P) or VDS-->VRB + P). RESULTS Objective response was observed in 31.1% of patients in the VRB arm versus 8.9% of those in the VDS arm (P = 0.0002). The median duration of response to VRB was 18.5+ weeks (range, 7.9 to 107.5+ weeks) compared with 11.7+ weeks (range, 6.0 to 35.0+ weeks) for VDS. Of the 69 patients who failed to respond to initial monotherapy, 33 in the VRB group who subsequently received VDS + P did not respond and 13 (26.5%) of 49 initially on VDS who received subsequent VRB + P responded. The rates of grades 3 and 4 leukopenia were similar in the two monotherapy arms (VRB, 55.3% vs. VDS, 48.5%). However, grade 3 anemia was more frequent in the patients on VRB than in those on VDS. The incidence of peripheral neurotoxicity was significantly higher with VDS than with VRB (P = 0.002), but VRB induced a slightly higher rate of local cutaneous reaction than VDS (P = 0.012). With the combination of cisplatin and these vinca alkaloids, peripheral neurotoxicity was less frequent in the VRB group than in the VDS group. CONCLUSION Our results demonstrate that VRB yields a higher response rate than VDS in stage IIIB or IV NSCLC, with the same extent of toxicity in terms of leukocytopenia. The peripheral neurotoxic effects were also milder with VRB than with VDS. In second-line chemotherapy, there was a notable difference in response between the VRB + P and VDS + P regimens.

Abstract
A late phase II study of LY188011 (gemcitabine hydrochloride), a new nucleoside derivative, in patients with non-small-cell lung cancer (NSCLC) was conducted at 24 Japanese institutions shown in Table 1 with a total of 69 patients enrolled. Of these, 67 were eligible and 64 completed at least one course of LY188011 therapy. The response rates (partial response only) in these populations were 20.9% (14/ 67) and 21.9% (14/64), respectively. Serious adverse reactions were septic shock and interstitial pneumonia in one patient each. Grade 3 or 4 adverse reactions included neutropenia (22.7%), decreased hemoglobin (13.4%), leukopenia (10.4%), anorexia (10.4%), malaise (7.5%), and nausea/vomiting (6.0%). Based on these results, it may be concluded that LY188011 has a high efficacy and benefit for the treatment of NSCLC.

Abstract
LY188011 (Gemcitabine hydrochloride) is a new derivative of deoxycytidine. Phase I study was carried out by a cooperative study group. LY188011 was administered weekly for 3 consecutive weeks starting with an initial dose of 60 mg/m2 (1n) and then increasing the dosage to 1,000 mg/m2 (16.7n). Dose limiting factor was found to be myelosuppression (decreases of WBC, neutrophils and platelet), and MTD was considered to be 1,000 mg/m2. The nadir of WBC and platelet were observed after about 1-3 weeks. It took 1-2 weeks for their recovery. Other adverse reactions included fever, fatigue, anorexia, nausea/vomiting, anemia and transient elevations of GOT and GPT. However, those adverse reactions were mild. T1/2 rho of plasma concentration was about 19 min and the C5min was dependent on the dose. Anti-cancer effects were observed in one gastric cancer and two colon cancer patients. It is recommended that the dosing schedule for an early phase II study is 800 mg/m2 weekly for 3 weeks with 1 week of rest as one cycle, in multiple cycles.

Abstract
We analyzed 29 pairs of primary and metastatic lung carcinomas obtained at autopsy for mutations in the p53 gene, using the polymerase chain reaction-single strand conformation polymorphism method (PCR-SSCP). We examined the relationship between p53 gene mutations and the development of metastasis, and the stability of p53 gene mutations during chemotherapy. The tumors consisted of six small cell carcinomas, 13 adenocarcinomas, eight squamous cell carcinomas, one large cell carcinoma, and one adeno-squamous cell carcinoma. PCR-SSCP analysis showed that three small cell carcinomas (50%), three adenocarcinomas (23%), two squamous cell carcinomas (25%), and one large cell carcinoma (100%) had p53 gene mutations. All these abnormalities were found between exon five and exon eight. The mutations in the primary tumors and the metastatic tumors were identical. These results suggest that p53 gene mutations occur before distant metastases develop, and that they may be stable during the process of metastasis. There were nine metastatic tumor samples that existed before the patients received chemotherapy. These samples showed identical p53 mutations as the corresponding primary tumor. This suggests that anticancer drugs rarely induce p53 gene mutations.

Abstract
PURPOSE This phase II study was conducted to evaluate the efficacy and toxicity of moderate-dose (60 mg/m2) docetaxel in Japanese patients with previously untreated advanced (stage IIIB or IV) non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Docetaxel 60 mg/m2 was administered intravenously over 1 to 2 hours to patients with previously untreated stage IIIB or IV NSCLC. Treatment was repeated every 3 weeks. No routine premedication was given. The patients' median age was 67 years (range, 40 to 80). Forty-four patients (59%) had adenocarcinoma and 55 (73%) had stage IV disease. The median Eastern Cooperative Oncology Group (ECOG) performance status (PS) was 1. RESULTS Seventy-five patients were eligible and treated with docetaxel. Fourteen patients (19%) achieved a partial response (PR); response was not significantly affected by histology or clinical stage. The median survival time for all patients was 297 days. The predominant toxicity was neutropenia, with 87% of patients experiencing grade 3 or 4. Febrile neutropenia was seen in eight patients. Hypersensitivity and edema each occurred in only 4% of patients and were easily manageable. There was no possible treatment-related death of acute exacerbation of pneumonitis. CONCLUSION Docetaxel 60 mg/m2 showed significant activity in advanced NSCLC, with a low incidence of hypersensitivity or peripheral edema. Further investigation of this agent in NSCLC is warranted, especially in combination with other active drugs.

Abstract
We conducted a multi-institutional (11 facilities), early phase II study of BMS-181339 (paclitaxel), a novel anti-cancer drug, for non-small cell lung cancer (NSCLC). The 150 mg/m2 dose of paclitaxel was given by intravenous infusion over 24 hours every three weeks. When fifteen patients were accumulated, the interim review revealed that three of 15 eligible patients had a partial response for a response rate of 20%. The most common toxic effects were grade 3 or 4 leukopenia seen in 73.3% (11/15), and grade 4 neutropenia in 93.3% (14/15). One patient with neutropenia had suspected septic shock, which could be managed by G-CSF and antibiotics. No serious hypersensitivity reaction was seen with premedication of anti-allergic drugs, although mild allergic reactions such as skin rash and flush, were observed in 20.0% (3/15). Other adverse reactions, including alopecia, fever, arthralgia, myalgia and peripheral neuropathy, were mild in most cases. We conclude that it is relevant to proceed to a late phase II study for NSCLC.

Abstract
We have reported our "new questionnaire of QOL (quality of life) in anti-emetic therapies during cancer chemotherapy" and demonstrated its reliability and validity. In the present study we investigated the utility of tropisetron capsules for delayed nausea and vomiting induced by cancer chemotherapies with CDDP single administration in a placebo-controlled double-blind comparative study using the questionnaire. The questionnaire was composed of the following scales: a physiological scale (appetite, feeling, vomiting, nausea), a psychological scale (sleep, mental fatigue, anxiety, pain, abdominal condition), a respiratory condition related scale (sputum, respiratory distress), an active scale (daily life in a hospital), a social relation scale (understanding of the family), a linear analogue scale for evaluation of the influence of nausea and vomiting in patient's life during 24 hours, and a face scale as the global scale. First, all patients were administered a preventive dose of tropisetron capsule on day 1 (the day of CDDP administration) and then allotted to once-daily oral administration of either a tropisetron (T group) or a placebo (P group) capsule during days 2 to 5 by a double-blind method. Chronological changes of QOL during the study period were measured by the area under the curve (AUC) generally used for calculation of blood levels of drugs. The maximum fluctuation (Difmax) of QOL scores throughout the whole study period was also evaluated. The data were collected from 114 cases, and 98 cases (51 in P group, 47 in T group) were analyzed. 1) The total score or 13 items (a modified linear analogue scale with 5 graduations), the face scale and linear analogue scale of T group were higher (better) than those of P group. 2) As for the total score of each scale, the physiological, psychological and active scales in the T group showed higher (better) levels than the P group. 3) As for the AUC values, the T group was lower (better) than the P group in most items. In AUC of the total score of 13 items, the face scale, the physiological and the psychological scales, the T group was significantly superior to the P group. 4) AUC levels of each item belonged to the physiological and the psychological scales in the T group tended to be lower (better) than the P group, and "sleep" and "pain" in the psychological scale were significantly lower (better) in T group than P group. 5) In Difmax values, all scales except respiratory condition related scale showed lower levels (better) in T group and the total score of 13 items, the face scale and the physiological and psychological scales showed significantly lower levels than P group. 6) Difmax values in each item belonging to the physiological and psychological scales showed lower levels in the T group, while "appetite" and "vomiting" in the physiological scale and "sleep" in the psychological scale showed significantly lower levels (better) than those of the P group. 7) In the stratified analysis performed for patients without nausea and vomiting on the 1st day of chemotherapy, there was no significance in AUC levels of all items in both groups. In patients with nausea and vomiting on the 1st day, the total score of 13 items, the face scale, the physiological and the psychological scales in the T group were significantly better than in the P group. 8) It was suggested that the anti-emetic efficacy of tropisetron for delayed nausea and vomiting might reduce the undesirable influence of chemotherapy on QOL, especially on the physiological and the psychological effects. These results suggested that this new questionnaire is applicable for evaluation of the utility of anti-emetics in patients in cancer chemotherapy, and that tropisetron capsules could reduce the decrease of QOL in delayed nausea and vomiting induced by chemotherapy.

Abstract
A new questionnaire on QOL of patients with chemotherapy-induced emesis and vomiting was developed, and its reliability and validity were investigated in the present multi-center clinical trial. The questionnaire consisted of 15 items which included descriptive questions on appetite, feeling, sleep, mental fatigue, anxiety, pain, sputum, respiratory distress, nausea, vomiting, abdominal condition, daily life in a hospital and relationship with family, a linear analogue scale representing influence of nausea and vomiting on patient's life during 24 hours, and a face scale as the global scale. Data from 98 patients with cancer were analyzed by principal component analysis and correlation analysis. The results were summarized as follows: 1) Recollect rate was 78.1% and complete response rate was 86.0% in this QOL measurement. 2) A clear correlation was observed between appetite, feeling, nausea, vomiting and the physiological scale, between sleep, mental fatigue, anxiety, pain, abdominal condition and the psychological scale, between sputum, respiratory distress and the respiratory condition related scale, between daily life in hospital and the active scale, between relationship with family and the social relation scale. These results satisfied internal consistency. 3) As for test-retest reliability, the total score of 13 descriptive items between the day before and two days before the start of chemotherapy showed no significant difference. 4) The 13 items were grouped into physiological, the psychological, the respiratory condition related, the active and the social relation scales, and these scales belonged to a different dimension. 5) The linear analogue scale, the face scale and the total scores of 13 descriptive items correlated respectively with all of items except item of, relationship with family. 6) As for concurrent validity, vomiting frequency, severity of nausea and anorexia correlated with the physiological scale. Severity of nausea and anorexia also correlated with the psychological and active scales. 7) As a result of investigation of sensitivity, the total score of the 13 descriptive items, the linear analogue scale representing influence of nausea and vomiting on patient's life during 24 hours and the face scale revealed the poorest levels 2-3 days after chemotherapy but recovered thereafter. The aggravation of QOL of patients treated with chemotherapy was reduced in the anti-emetic administration group compared with the placebo administration group. These results suggested that this new questionnaire developed for chemotherapy-induced emesis and vomiting had sufficient validity and reliability to reflect the effects of anti-emetic drug.

Abstract
Twenty-four previously treated patients with refractory or relapsed small cell lung cancer (SCLC) were entered into a prospective, multicenter phase II study. All 24 patients had been pretreated with some form of cisplatin-based chemotherapy. The median time of chemotherapy was 4.2 months (range 1.4-9.4 months). Patients were treated with a dose of 25 mg/m2 of vinorelbine weekly. Twenty-four patients were eligible for response and for toxicity. Partial response was observed in 3 out of 24 eligible patients (12.5%; 95% confidence interval, 2.7-32.4%). All 3 patients who responded had previous chemotherapy including vincristine. The most common toxicity was leukopenia (91.7%, 66.7% in WHO 3-4 grade) and anemia (70.8%, 20.8% in WHO 3 grade). Nonhematological toxicities were moderate and mild. These results support a two-state sequential study design of previously untreated patients for further phase II study in SCLC.

Abstract
A phase I study (open trial) of bicalutamide (Casodex), a non-steroidal antiandrogen, was conducted on 16 patients with prostatic cancer (stage C to D). The patients were given 10, 30, 50, 80 or 100 mg of bicalutamide orally daily for 12 weeks. Adverse reactions were observed in 8 out of 16 patients, but almost all were mild. Breast pain, gynecomastia and hot flushes were observed in 6 patients. Adverse reactions regarding liver function tests were observed in 3 patients. These were increased glutamic-oxalacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), alkaliphosphatase (AL-P) or gamma guanosine 5'-triphosphate (gamma-GTP). However, during or after the treatment period the elevated values were reversed to the pretreatment level. In terms of efficacy, anti-tumor effect was observed in 1 or 2 patients at each dose. Serum concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone and estradiol increased during treatment. Plasma concentrations of the R (-) enantiomer, which has antiandrogenic activity, reached the steady state 6-8 weeks after the initiation of treatment; its apparent plasma elimination half-life observed following repeated administration was 8.4 +/- 1.1 days. In conclusion, bicalutamide (10-100 mg od) is considered to be tolerated well enough to be administered to patients with prostatic cancer and has shown evidence of anti-tumor effect.
