Irinotecan has appeared to have significant activity against previously treated and untreated small-cell lung cancer (SCLC). The major toxicities of irinotecan are neutropenia and diarrhea, although there is interpatient variability in the severity of symptoms. The combination of irinotecan and cisplatin is likewise significantly active against SCLC, with an acceptable toxicity profile. A phase III study comparing irinotecan and cisplatin with etoposide and cisplatin has been conducted in the treatment of previously untreated patients with extensive disease SCLC. The results of this study may define a new standard care for SCLC. Irinotecan and etoposide is also an active new combination in the treatment of both previously treated or untreated SCLC. Neutropenia was the most commonly observed toxicity in this combination; there were no severe gastrointestinal toxicities, including diarrhea.

The purpose of this study was to evaluate the efficacy and safety of docetaxel as first- and second-line chemotherapy for advanced non-small cell lung cancer (NSCLC) under routine clinical conditions. Two hundred and three patients with advanced NSCLC received docetaxel 100 mg/m2 (1-h intravenous infusion) every 3 weeks, with oral corticosteroid pre-medication, of whom 173 were eligible. Median age was 60 (29-78) years and median Karnofsky performance status was 80% (60-100). A total of 77% of patients had metastatic disease, 33% had bone metastases and 18% had liver metastases. The treatment was second-line or more for 72 patients (35%). Overall response rates in the eligible population were 19.7% [95% CI, 12.5-23.0] for both treatments, 22.6% for first-line treatment and 13.8% for second-line treatment. Median survival was 8.3 months and 1-year survival was 35% for the overall population (8.7 months and 38%, respectively, for patients receiving first-line treatment and 7.2 months and 27%, respectively, for patients receiving second-line treatment). Neutropenia, grade 3 and 4, occurred in 57% of the cycles and 5% of patients experienced febrile neutropenia. Alopecia (62% of patients), neuro-sensory symptoms (32%), asthenia (28%), diarrhea (22%), nausea (22%) and nail disorders (20%) were the most common non-hematological adverse effects. A total of 33% of patients suffered fluid retention, despite the use of corticosteroid pre-medication, but this was only severe in 1.5% of patients. It was possible to confirm the efficacy of docetaxel as a single agent for first- and second-line chemotherapy in a large patient population treated in a community setting.

Based on the results of our previous pilot study, we conducted a multi-institutional phase II study of combination chemotherapy consisting of oral UFT (Taiho Pharmaceutical Co. Ltd, Tokyo) plus cisplatin (CDDP) in patients with advanced non-small cell lung cancer (NSCLC). UFT capsule containing 100 mg tegafur and 224 mg uracil was orally administered in two divided doses on days 1 through 21 making the total tegafur dose 400 mg/m(2)/day (maximum 600 mg/body). CDDP was administered by drip infusion at a dose of 20 mg/m(2) on a 5-day schedule from day 8 to 12. Treatment was repeated every 4 weeks as long as the criteria for initiation of therapy were still met. Between April 1995 and March 1997, 51 patients were entered into the study. The mean age of all 50 eligible patients was 64 years(range: 40-78). There were 21 patients with clinical stage IIIB disease and 29 patients with IV disease. Thirty-two patients had adenocarcinoma, 14 had epidermoid carcinoma, and four had large cell carcinoma. Of the 47 assessable patients, 18 achieved a partial response with an overall response rate of 38.3% (95% confidence interval: 24.4-52.2%). The median response duration was 113 days. The median survival time of the eligible patients was 12.8 months, and the 1-year survival rate was 54%. Among the 51 patients enrolled, grade 3 or 4 leukopenia developed in one patient (2%), neutropenia in six patients (11. 8%), thrombocytopenia in six patients (11. 8%), and anemia in three patients (5. 9%). Non-hematological grade 3 or 4 toxicities included anorexia in 10 patients (19.6%), nausea in ten (19.6%), vomiting in two (3.9%), and diarrhea in two (3. 9%). Grade 3 abnormal laboratory data included bilirubinemia in four (7. 8%), GPT elevation in one (2.0%), and hematuria in one (2.0%). In conclusion, combination of CDDP plus oral UFT is efficacious, with low toxicity, in the treatment of advanced NSCLC. In particular, the low hematological toxicity may warrant application of this regimen to the treatment of elderly patients and in trials of concurrent chemoradiotherapy in patients with locally advanced NSCLC.

Cisplatin (Platinol)-based chemotherapy has been the standard systemic therapy for both non-small-cell and small-cell lung cancer for the past 2 decades, though the efficacy and benefit remain modest. Recently, several novel agents have been introduced that have single-agent activity comparable to cisplatin and offer the possibility of improved therapy for lung cancer. Camptothecin and taxane derivatives are associated with both different mechanisms of action and nonhematologic toxicities, and have demonstrated additive or synergistic activity when used in combination in preclinical studies. We review pertinent clinical studies of these agents in lung cancer and present our experience in combining irinotecan (Camptosar, CPT-11) with taxanes on a weekly schedule in dose-finding and efficacy studies. When chemotherapy is delivered for 4 consecutive weeks followed by a 2-week rest, hematologic toxicity is dose limiting and most prominent during weeks 3 and 4. Dose intensification is feasible if the schedule is modified so the chemotherapy is given on days 1 and 8, with cycles repeated every 3 weeks. The most common nonhematologic toxicities remain asthenia, neuropathy, and diarrhea. Future studies will explore and better define the role of these drug combinations in the treatment of lung cancer.

Numerous epidemiologic studies suggest a relationship between lung cancer and peptic ulcer disease. Furthermore, various lung cancers synthesize and release a number of peptides such as gastrin and gastrin-releasing peptide that could cause acid hypersecretion; however, Zollinger-Ellison syndrome (ZES), because of a lung tumor, has never been described. We report such a patient for the first time. A 60-year-old man with a non-small cell lung carcinoma (large cell type) presented with diarrhea, heartburn, abdominal pain, and duodenal ulcers. Evaluation showed ZES was present (fasting hypergastrinemia, hyperchlorhydria) and control of all symptoms by omeprazole. No abdominal or cardiac tumor, the other known locations of gastrinomas causing ZES, was found on detailed tumor imaging studies. Resection of the lung tumor resulted in a decrease in gastrin levels to normal values. Plasma radioimmunoassays showed elevated gastrin, chromogranin A and normal levels of gastrin-releasing peptide, and 9 other hormones. The tumor showed similar immunocytochemical results. The characteristics of this case are compared with 100 cases of sporadic abdominal gastrinomas, and the evidence reviewed suggests why ZES should be considered in patients with lung cancer with peptic symptoms.

It has been reported that 7-ethyl-10-[4-(1-piperidino)-1-piperidino]carbonyloxy-camptothecin (CPT-11) and its active metabolite, 7-ethyl-10-hydroxy-camptothecin (SN-38), have absorption characteristics of weakly basic drugs, suggesting that alkalization of the intestinal lumen might reduce reabsorption and its attendant side effects. Furthermore, stasis of stools containing these compounds is thought to induce damage to the intestinal mucosa. The prevention of CPT-11-induced side effects by oral alkalization (OA) combined with control of defecation (CD) was estimated in a case-control study of lung cancer patients. Coinciding with day 1 of CPT-11 infusion and for 4 days thereafter, OA and CD were practiced utilizing orally administered sodium bicarbonate, magnesium oxide, basic water and ursodeoxycholic acid. OA involved the daily use of all four therapeutics, and CD required doses of up to 4.0 g/day of magnesium oxide and 2 L/day of excess basic water. From three ongoing prospective phase I/II studies, we selected 37 consecutive patients who were treated with CPT-11 in combination with cisplatin in the presence of OA and CD (group B). Thirty-two control subjects who were matched to the background characteristics of the case patients were treated with the same regimen in the absence of OA and CD (group A). Toxicities induced by the CPT-11/cisplatin combination were evaluated and analyzed in group A and group B in a case-control format. The use of OA and CD resulted in significantly higher stool pH (p < 0.0001), while reducing the incidence of delayed diarrhea (> or = grade 2: group A 32.3% versus group B 9.4%; p = 0.005), nausea (p = 0.0001), vomiting (p = 0.001) and myelotoxicity, especially granulocytopenia (p = 0.03) and lymphocytopenia (p = 0.034). In addition, dose intensification was well tolerated in patients receiving OA and CD, allowing dose escalation from 35.6 +/- 6.0 to 39.9 +/- 5.6 mg/m(2)/week (p < 0.001). Tumor response rates for non-small cell lung cancer were 59.3% (16/27 patients) in group B compared with 38.5% (10/26 patients) in group A. Multivariate analysis revealed that the risk of CPT-11-induced delayed diarrhea greater than grade 2 was associated with OA and CD (odds ratio for delayed diarrhea, 0.14 with use of OA and CD; 95% confidence interval, 0.05 to 0.4; p = 0.0002) and age (odds ratio, 1.08 per increase in age; 95% confidence interval, 1.02 to 1.15; p = 0.009). OA and CD appear to be useful in preventing the dose-limiting side effects of CPT-11 noted in clinical practice, mainly nausea, vomiting, granulocytopenia and especially delayed diarrhea. Risk factors statistically associated with delayed diarrhea include advanced age and the use of CPT-11 without OA and CD.

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 x m(-2) was given first and followed by CPT-11 at a dose of 50 mg x 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.

Clostridium difficile associated diarrhoea or Pseudomembranous colitis occasionally occurs without prior antibiotic usage. While the association of chemotherapy and Clostridium difficile infection has previously been well recorded, the true incidence is unknown. We report a case of Clostridium difficile associated diarrhoea after chemotherapy for lung cancer. The fatal outcome in this case and the increasing use of chemotherapy in this country highlights the need to have a high index of suspicion in any case of unexplained diarrhoea post chemotherapy. A review of the literature is presented.

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.

Gemcitabine (2',2'-difluorodeoxycytidine) is a nucleoside analog with antitumor activity against a variety of malignancies. The critical enzyme cytidine kinase is saturated at plasma concentrations achieved after a 30-min infusion at conventional doses. Prolonged infusion time may yield higher intracellular dFdCTP concentrations. A phase I study was designed to determine the maximum tolerated dose (MTD) of gemcitabine, given by infusion for 3 h, in heavily pretreated patients. Twenty-seven patients (13 head and neck cancer, seven sarcoma, three esophageal cancer, three non-small-cell lung cancer and one ovarian cancer) were enrolled. Twenty patients were defined as refractory at first- or second-line chemotherapy. Four different entry dose levels (300, 400, 450 and 500 mg/m(2)) were evaluated for gemcitabine administered on days 1, 8 and 15 of a 28-day cycle. The MTD was defined as 450 mg/m(2), with granulocytopenia, thrombocytopenia and asthenia being dose limiting. The maximum grade III/IV patient toxicities for hemoglobin, leukocytes, neutrophils and platelets for all doses were 7, 19, 19 and 11%, respectively. Non-hematological toxicities included asthenia, nausea/vomiting and diarrhea. Thus, gemcitabine administered at a fixed 3-h infusion was well tolerated up to 450 mg/m(2) in heavily pretreated patients. Myelosupression and asthenia were dose-limiting toxicities.
