Thirty-six patients with advanced epithelial ovarian cancer received epirubicin as second-line therapy after primary treatment with carboplatin and cyclophosphamide. Thirty-four patients were evaluatable for response, 36 for toxicity. There were 9 responses (response rate 26.4%, 95% CI = 12.9-44.4), 2 complete and 7 partial. Median duration of response was 149 days (range 42-183); 4 patients with partial remission are still on study. Toxicity consisted of fatal cardiac failure and paravenous injection (1 patient), fatal leukopenia and sepsis (1 patient), and severe loss of appetite, nausea and vomiting, fatigue, and general malaise in 3 patients. Platelet nadir grade 4 (WHO) was observed in 2 patients while leukocyte nadir grade 4 was seen in 3 patients. The present study showed a high response rate from standard-dose epirubicin. Toxicity was acceptable in most patients, but 2 patients died from treatment complications which gives a treatment-related mortality rate of 6%. Response was primarily seen in patients with minor tumor load and in good general condition.

This randomized, multinational, multicenter study was designed to determine the response rate of gemcitabine monotherapy and cisplatin/etoposide combination therapy in chemotherapy-naive patients with advanced, recurrent, and/or metastatic non-small cell lung cancer (stage IIIA [if inoperable], IIIB, or IV). One group of patients received gemcitabine 1,000 mg/m2 intravenously once a week for 3 weeks (days 1, 8, and 15) followed by a 1-week rest period. The second group received cisplatin 100 mg/m2 intravenously on day 1 of each 28-day cycle in combination with etoposide 100 mg/m2, administered on days 1, 2, and 3 following the cisplatin infusion. Each patient was allowed to remain on study up to a maximum of six cycles. The planned interim analysis was based on the 117 patients in the study, 116 of whom were randomized up until November 20, 1995. The efficacy analysis was performed on the 107 patients who had data from a minimum of two cycles, whereas the safety analysis was based on data from all 116 randomized patients. In the gemcitabine arm there were 10 of 52 (19%) partial responders; in the cisplatin/etoposide arm there were four (7%) of 54 partial responders. There was a statistically significant difference in the response rates between the two arms, with a 95% confidence interval of 0.6% to 32.1% (P = .040). The median time to progressive disease was 4.2 months for gemcitabine patients and 3.7 months for cisplatin/etoposide patients. There was significantly more alopecia and nausea and vomiting in the cisplatin/etoposide arm compared with the gemcitabine arm, as well as two cases of neutropenic sepsis in the cisplatin/etoposide arm. These data indicate that single-agent gemcitabine is at least as effective as the combination of cisplatin/etoposide in the treatment of advanced non-small cell lung cancer and has an improved safety profile.

9-Nitrocamptothecin (9NC) is a water-insoluble topoisomerase I inhibitor with a broad antitumor activity in animal models. To determine the maximum tolerated oral dose (MTD), a phase I study was performed in patients with advanced cancer refractory to conventional chemotherapy. 9NC was administered orally with escalating doses to cohorts of five patients beginning at 1 mg/m2/day for five consecutive days every week for 4 weeks. Increments were 0.5 mg/m2/day for each cohort. Toxicity was evaluated in 28 patients diagnosed with various malignancies. Seven patients received 1 mg/m2/day for 28 weeks; 10 patients, 1.5 mg/m2/day for 68 weeks; and 26 patients, 2 mg/m2/day for 159 weeks. At 1.5 mg/m2/day or higher, the dose-limiting toxicity was hematologic, with grade 4 anemia in eight (29%); neutropenia in seven (25%) and thrombocytopenia in five (18%). Grade 2 or higher toxic effects occurred at each dose level: nausea and vomiting in 15 (54%), diarrhea in nine (32%), chemical cystitis in seven (25%), neutropenic sepsis in six (21%) and weight loss in five (18%) (N=28). Responses were observed after 2-8 weeks of therapy in five patients with pancreatic, breast, ovarian and hematologic tumors. Fourteen patients had a disease stabilization and one patient received treatment up to 18 months. The MTD of 9NC given orally has been estimated at 1.5 mg/m2/day for five consecutive days weekly. 9NC may be tolerated for sustained periods of time, but has the potential for significant hematologic, gastrointestinal and urinary bladder toxicity. Significant antitumor activity was observed, warranting further clinical investigations.

9-Nitrocamptothecin (9-NC) is a water-insoluble topoisomerase I inhibitor with a broad antitumor activity in animal models. A phase II study was performed in patients with heavily refractory ovarian, tubal or peritoneal cancer (median number of previous chemotherapy regimens > 3) to determine the activity of a daily oral dose of 9-NC. 9-NC dose was 1.5 mg/m2/day for four consecutive days every week. Increments of 0.25 mg/day were authorized in patients without significant side effects. Of 29 evaluable patients, a 7% remission rate was observed. Thirty-four percent of patients had stable disease. The median survival was 8 months. Toxicity was evaluated in 31 patients. Grade 3 or 4 hematologic toxicity consisted of anemia in 10 patients (32%), neutropenia in eight (26%) and thrombocytopenia in three (10%). Grade > or = 2 non-hematologic toxic effects were nausea and vomiting in 26 (84%), diarrhea in 12 (39%), weight loss in seven (22%), chemical cystitis in six (19%) and neutropenic sepsis in six (19%). 9-NC was tolerated for sustained periods of time in some patients (up to 47 weeks). The observed 8-month survival in such a refractory patient population is noteworthy. Further clinical research of prolonged exposure to less toxic analogs of 9-NC is warranted.

A previously healthy 15-year-old female was admitted to our hospital complaining of nausea and vomiting. She did not complain of diarrhea. A physical examination revealed a lower right quadrant abdominal tenderness without rebound or spontaneous pain and a knocking pain of the costovertebral angle. A high fever, knocking pain of costovertebral angle, and urinary findings including Gram's stain, lead us to suspect a urinary tract infection, cefotiam was administered intravenously. Spiking fever with shaking chills continued for three days, and three sets of blood cultures were positive for Salmonella Oranienburg, but her urine culture was negative. Her history was taken again, revealing an intake of a processed squid product. The product was confirmed by the local public health center to be Salmonella Oranienburg. Finally food poisoning by Salmonella Oranienburg with sepsis was diagnosed. With cefotiam she became better and was discharged from the hospital on the 10th hospital day. During admission to the hospital she did not experience any diarrhea, and her stool culture was negative. Epidemics of Salmonella Oranienburg food poisoning are relatively rare in the literature. In Japan, one has arisen as a result of contamination of a processed squid product in March 1999. However, there have been no cases without so-called gastroenteritic symptoms (abdominal pain and diarrhea) who were previously healthy and developed sepsis caused by Salmonella Oranienburg, reported in Japan. Even in previously healthy patients, with an epidemic situation of non-typhoidal salmonellosis, salmonella sepsis must be ruled out. Among such cases, those who present with spiking fever and shaking chills should be given antibiotic therapy after taking appropriate cultures.

Anthracyclines and cisplatin have been shown separately to have modest activity in prostate cancer. The synergism between anthracyclines and cisplatin, with the lack of overlapping toxicities, led to the conduct of this phase II trial of the combination of epirubicin and cisplatin in hormone-refractory metastatic prostate cancer. Twenty-one evaluable patients with hormone-refractory metastatic prostate cancer received epirubicin 100 mg/m2 followed by cisplatin 80 mg/m2 with prehydration and mannitol diuresis. Epirubicin and cisplatin produced a biochemical response (>50% decrease in tumor marker) in 32% of patients, symptomatic improvement in 38%, and a response in measurable and evaluable disease sites in 14%. Toxicities were mainly hematologic, with 77% and 41% >grade 2 neutropenia and thrombocytopenia, respectively. Greater than grade 2 toxicities were: cardiac (three), renal secondary to sepsis (one), nausea and vomiting (two), weakness (one), mucositis (one), and diarrhea (one). The combination of epirubicin and cisplatin was associated with manageable toxicities in this elderly population; however, antitumor activity was marginal in this disease. Participation in clinical trials should continue to be offered to patients with hormone-refractory metastatic prostate cancer.

The objectives of the present study were to determine the following: (a) the maximum tolerated dose (MTD) of melphalan using a 24-h continuous infusion; (b) the clinical toxicity; and (c) the pharmacokinetic characteristics of melphalan at each dose level. Twenty-one patients with refractory solid tumors were enrolled in the study. Melphalan, packaged in 3% sodium chloride, was administered i.v. over a 24-h period. Patients were assigned to one of three escalating dose levels of melphalan: (a) 20 mg/m2 (n = 5); (b) 30 mg/m2 (n = 7); and (c) 40 mg/m2 (n = 6). Each patient underwent pharmacokinetic evaluation during the first cycle of treatment. Melphalan concentrations in plasma were determined by high-performance liquid chromatography. Toxicity was evaluated after each course of chemotherapy. All of the patients were assessable for toxicity and pharmacokinetics, and 20 patients were assessable for response analysis. A total of 50 courses of melphalan was studied. The MTD was 30 mg/m2. The dose-limiting toxicity was neutropenia and thrombocytopenia. Hematotoxicity was reversible (nadir, 14-15 days; recovery, 3.5 and 12.5 days for 30 and 40 mg/m2, respectively), cumulative, and related to the administered dose and to the history of previous therapy. There were six episodes of neutropenic sepsis. Individual pharmacokinetic parameters were estimated using a Bayesian approach and linear elimination kinetics. Data were compatible with a one-compartment model. Relationships have been found between the area under the plasma concentration-time curve and doses and between Css and doses. Moreover, clearance, t1/2 elimination, and volume of distribution did not change statistically with dose, which suggests linear kinetics. Two partial responses were observed in patients with ovarian carcinoma or adenocarcinoma of unknown primary origin, and another patient had stabilization disease. In conclusion, melphalan MTD was determined to be 30 mg/m2 when administered as a 24-h infusion. Hematological toxicity was the dose-limiting toxicity. The most important nonhematological toxicity encountered was nausea and vomiting. The recommended dose for Phase II studies was 30 mg/m2.

Our objective was to describe clinical features and predisposing factors attributed to lactic acidosis in 4 HIV-infected patients on long-term nucleoside reverse transcriptase inhibitor (NRTI) therapy. All patients had received at least 6-20 months of NRTI-containing antiretroviral therapy: all used stavudine (d4T), in one combined with lamivudine (3TC), in the other 3 with didanosine (ddI); in one hydroxyurea was added. In all, the initial symptoms were gastrointestinal (nausea and vomiting), followed by tachypnoea preceding the lactic acidosis; death followed 6-22 days after admission (liver failure and uncontrollable arrhythmias). Treatment with riboflavin was unsuccessful in one patient. The only definite risk factor in all cases was NRTI-induced mitochondrial toxicity; one patient was concomitantly treated for Kaposi's sarcoma (with bleomycin and vinblastine) and one just recovered from pneumococcal sepsis. None of the patients had a history of chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. In all patients, some sort of toxicity to other previously used NRTIs had occurred earlier. Lactic acidosis occurred after months of NRTI therapy in patients who had already suffered other forms of NRTI toxicity. Concomitant diseases or comedication might have aggravated the mitochondrial toxicity of the NRTIs. Screening methods to detect mitochondrial toxicity are necessary, since lactic acidosis occurs rather unexpectedly, with a rapid, fatal course.

The activity and toxicity of topotecan in women with recurrent cervical cancer are described from a case series of women with recurrent cervical cancer who had measurable disease and were not amenable to cure by surgery or radiation. All patients had prior platinum-based chemotherapy and developed progressive disease. Topotecan was given as 1 mg/m2/day over 30 min for 5 days every 3 weeks until progression of disease or prohibitive toxicity. Between July 1998 and July 1999, 12 patients received a total of 20 cycles of topotecan. Median age was 41 years (range 21-62), and 11 (92%) patients had prior whole pelvic radiation. The mean number of topotecan cycles was 1.5 (median 1, range 1-3). There were two partial responses (16.7%; 95% CI, 2% to 48%), both in prior radiation fields. Five patients required red blood cell transfusions, four had grade II nausea and vomiting, two developed sepsis (one with neutropenia), one developed fever, and one reported hyperpigmentation. There were no treatment-related mortalities. Although topotecan appears to exhibit modest activity in recurrent cervical cancer after radiation and platinum-based therapy, bone marrow toxicity may limit the utility of this regimen without hematopoietic growth factor support.

Carcinoma of unknown primary site remains a common clinical diagnosis, accounting for between 5 and 10% of all cancer patients. Numerous combination chemotherapy regimens have been used in the management of carcinoma of unknown primary site, resulting in response rates of 0-48%. We present the results of a single centre phase II study of the use of the combination of mitomycin C (7 mg m(-2) on day 1 of cycles 1, 3 and 5) cisplatin (60 mg m(-2) on day 1) and continuous infusion 5-fluorouracil (300 mg m(-2) daily), MCF, delivered as a 21-day cycle, in patients with carcinoma of unknown primary site. Thirty-one patients with a diagnosis of carcinoma of unknown primary site were treated in Aberdeen Royal Infirmary between 1997 and 2001 with MCF. In total, 136 cycles of MCF were delivered (median of 5 cycles per patient). Toxicity was acceptable, with 19% grade 3 or 4 neutropenia, 16% grade 3 or 4 thrombocytopenia and 13% grade 3 or 4 nausea and vomiting. No cases of neutropenic sepsis were seen and there were no treatment-related deaths, however, six patients developed thrombotic complications. The overall response rate was 27% (CR 3%; PR 23%). Median time to progression was 3.4 months (95% CI 1.1-5.6 months) and median overall survival was 7.7 months (95% CI 5.7-9.8 months). Survival at 1 year was 28%, and at 2 years, 10%. MCF is a tolerable regimen with comparable toxicity, response rates and survival data to most platinum-based combination chemotherapy regimens in use for this devastating disease.
