Topotecan is a specific inhibitor to topoisomerase I. An oral formulation of topotecan is available with a bioavailability of 32-44% in humans. A phase I and pharmacological study of the oral formulation of topotecan administered daily for 5 days every 21 days was performed in adult patients with solid tumours to determine the maximum tolerated dose (MTD). Adult patients with a WHO performance status < or = 2 adequate haematological, hepatic and renal functions, with malignant solid tumours refractory to standard forms were entered into the study. Pharmacokinetics were performed on days 1 and 4 of the first course using a validated high performance liquid chromatographic assay. 29 patients entered the study, all patients were evaluable for toxicity and response. The doses studied in the 29 patients were 1.2, 1.8, 2.3, 2.7 mg/m2/day and a fixed dose of 4 mg/day without surface area adjustment. A total of 109 courses were given. Dose limiting toxicity (DLT) was reached at a dose of 2.7 mg/m2/day and consisted of CTC (NCI-Common Toxicity Criteria) grade IV granulocytopenia. The regimen was well tolerated. Non-haematological toxicities were mild, including fatigue, anorexia, nausea, vomiting and diarrhoea. A significant correlation was observed between the percentage decrease in white blood cells versus the area under the curve (AUC(t)) of topotecan lactone (R = 0.76 P < 0.01) which was modelled by a sigmoidal Emax function. The correlation coefficient between the absolute topotecan dose administered and the AUC(t) was R = 0.52 (P = 0.04). Pharmacokinetics of the fixed dose of 4 mg/day were comparable to the 2.3 mg/m2/day dose. DLT in this phase I study of five daily doses of oral topotecan every 21 days was granulocytopenia. The recommended dose for phase II studies is 2.3 mg/m2/day or alternatively, a fixed dose of 4 mg/day.

Carzelesin is a cyclopropylpyrroloindole analogue which acts as a DNA-sequence-specific alkylating agent. In this phase I study, Carzelesin was given as a 4-weekly 10 min i.v. infusion to 51 patients with advanced solid tumours. Patients received a median of two courses (range 1-5) at one of nine dose levels: 24, 48, 96, 130, 150, 170, 210, 250 and 300 microg m(-2). According to NCI-CTC criteria, non-haematological toxicities (grade 1/2) included fever, nausea and vomiting, mucositis and anorexia, none of which was clearly dose related. The dose-limiting toxicity was haematological and consisted mainly of neutropenia and to a lesser extent thrombocytopenia. From the dose level 150 microg m(-2), the haematological toxicity (particularly thrombocytopenia) was delayed in onset, prolonged and cumulative in some patients. In several courses, double WBC nadirs occurred. The maximum tolerated dose for a single course was 300 microg m(-2). From the dose level 170 microg m(-2), the intended dose intensity could not be delivered to most patients receiving > 2 courses owing to cumulative haematological toxicity. The dose level with the best dose intensity for multiple courses was 150 microg m(-2). The pharmacokinetics of Carzelesin and its metabolites (U-76,073; U-76,074) have been established in 31 patients during the first course of treatment using a HPLC method. Carzelesin exhibited linear pharmacokinetics. The concentration of U-76,074 (active metabolite) extended above the lower limit of quantitation (1 ng ml(-1)) for short periods of time and only at the higher dose levels. There was no relationship between neutropenia and the AUC of the prodrug Carzelesin, but the presence of detectable plasma levels of the active metabolite U-76,074 was usually associated with a substantial decrease in ANC values.

A 66-year-old man was found to have both advanced cancer of the middle thoracic esophagus and advanced cancer of the middle third of the stomach with paraaortic lymph node metastases. The prognosis was poor because of local advanced disease and distant metastasis. The patient was therefore given combined chemotherapy with TS-1 and cisplatin. TS-1 (80 mg/day) was administered on days 1 to 5, 8 to 12, 15 to 19, and 22 to 26 (weekday-on/weekend-off schedule), and cisplatin (70 mg/m2 intravenously over the course of 2 hours) was administered on days 1 and 15 of a 28-day cycle. After 2 courses of chemotherapy the esophageal lesion had a complete response, and the gastric lesion had a partial response (reduction ratio, 71.4%). However, stomatitis and anorexia of grade 2 (NCI-CTC) occurred. Two courses of TS-1 alone (80 mg/m2) were therefore given. The esophageal lesion continued to show a complete response and the gastric lesion a partial response (reduction ratio, 85.7%). There was no change in the para-aortic lymph node metastasis (No. 16a2 latero). No adverse reaction to chemotherapy was severer than grade 3, and a good response was obtained. These findings indicate that chemotherapy with a combination of TS-1 and cisplatin is effective against advanced esophageal cancer and advanced gastric cancer.

This is a preliminary feasibility study to assess the pharmacokinetics and efficacy of pentostatin in a patient undergoing dialysis. Pentostatin is a safe and well-tolerated medication, but a dose reduction is required for patients with renal insufficiency. We present a patient with chronic adult T-cell leukemia, whose white blood cell count exceeded 100 X 10(9)/l, and end-stage renal disease, receiving long-term thrice-weekly dialysis. The initial treatment with oral cyclophosphamide or with oral etoposide resulted in no response. After informed consent was obtained, pentostatin (1, 2, or 3mg/m2) was administered. 1 or 2 hours after injection, the patient received hemodialysis over 4 hours to remove any of the drug remaining in his system. Plasma concentrations of pentostatin were calculated with the known pharmacokinetics parameters. The differential equations describing a 2-compartment open-infusion pharmacokinetic model were fitted to the measured concentration-time data. Tumor lysis syndrome occurred 4 days after the course of the highest dose (3mg/m2), and the patient achieved complete remission. Anorexia, graded as 2 according to the NCI-CTC classification system, occurred and continued for four weeks. Pentostatin therapy consisting of the decreased dose (2mg/m2) was then administered every other week and provided a transient partial response with mild anorexia. Consequently, pentostatin can be considered as one of the chemotherapeutic regimens available for a patient undergoing dialysis.

Oxaliplatin (L-OHP) has been established as a key drug for advanced colorectal cancer, and combination therapy with 5-FU/Leucovorin (LV)(FOLFOX regimen) is commonly used in Europe and the US. A phase I study of modified (m) FOLFOX 6 therapy was conducted to determine the recommended dose (RD) of 5-FU infused for 46 hours. Inclusion criteria were unresectable advanced colorectal cancer,measurable lesions, performance status (PS; ECOG) 0-2, age 20-75 years, and adequate organ functions. L-OHP and l-LV was administered over 2 hours and followed by bolus injection and continuous infusion of 5-FU for 46 hours every 2 weeks. Two cycles of mFOLFOX 6 therapy were performed. Doses of L-OHP, l-LV, and bolus injection of 5-FU were fixed at 85 mg/m(2), 200 mg/m(2), and 400 mg/m(2), respectively. The dose of continuous infused 5-FU was escalated from 1,600 mg/m(2), (level 1), 2,000 mg/m(2), (level 2), 2,400 mg/m(2), (level 3), and 2,800 mg/m(2), (level 4). RD was determined in a dose escalation manner, and safety was evaluated according to NCI-CTC Ver 2.0. A total of 13 patients were enrolled. Male/female=7/6, PS 0/1/2=2/4/7, mean age 64 years (range 55-75). Thrombocytopenia was not observed, and grade 2 of neutropenia and peripheral neuropathy was observed in 4 and 6 out of 13 patients. No dose-limiting toxicity (DLT) was observed at level 1 (n=3), 2 (n=4), and 3 (n=4), but at level 4 (n=2), 2 patients experienced DLT; grade 3 easy fatigue and anorexia required treatment delay over 7 days. Level 3 was therefore determined as RD. A phase II study is ongoing to evaluate the efficacy of mFOLFOX 6 therapy.

The purpose of this study was to investigate the effectiveness and safety of palliative chemotherapy using S-1. We treated 19 advanced oral SCC patients including 8 men and 11 women with S-1. Of the 19 patients studied, two patients were classified as UICC Stage II, two patients as Stage III, 14 patients as Stage IV A, and one patient was classified as StageIV C. The ages varied from 54 to 9 1 years (mean ages; 78.3 years-old). The patients received this chemotherapy (80-120 mg/day) consisting of 2 weeks' administration including 5-days' administration and 2-days' termination (named 'Weekday-on/Weekend-off administration schedule' ) following 1 week rest. After this treatment, 7 CR and 4 PR were achieved, but the toxicities were only anorexia, leukopenia, thrombocytopenia, and uritication of NCI-CTC grade 1. The prognosis of 19 cases was 7 terminal by primary disease, 3 terminal by other disease, 7 lives with tumor bearing, and 2 lives without tumor bearing. We concluded that our novel S-1 administration method was extremely effective for oral SCC, including lymph node metastasis, providing high potential without any severe adverse effects for palliative therapy.

Radiation-induced acute intestinal symptoms (RIAISs) are the most relevant complication of abdominal or pelvic radiation. Considering the negative impact of RIAIS on patients' daily activities, the preventive effects of berberine on RIAIS in patients were investigated. Thirty-six patients with seminoma or lymphomas were randomized to receive berberine oral (n = 18) or not (n = 18). Forty-two patients with cervical cancer were randomized to a trial group (n = 21) and control group (n = 21). Radiotherapy used a parallel opposed anterior and posterior. 300-mg berberine was administered orally three times daily in trial groups. Eight patients with RIAIS were treated with 300-mg berberine three times daily from the third to the fifth week. Toxicities, such as fatigue, anorexia/nausea, etc., were graded weekly according to CTC version 2.0. Patients with abdominal/pelvic radiation in the control group showed grade 1 fatigue, anorexia/nausea, colitis, vomiting, proctitis, weight loss, diarrhea and grade 2 anorexia/nausea, fatigue. Only grade 1 colitis, anorexia/nausea, and fatigue were seen in patients of abdominal radiation treated with berberine. Grade 1 fatigue, colitis, anorexia/nausea, and proctitis occurred in patients of pelvic radiotherapy treated with berberine. Pretreatment with berberine significantly decreased the incidence and severity of RIAIS in patients with abdominal/pelvic radiotherapy when compared with the patients of the control group (P < 0.05). RIAIS were reduced in patients with abdominal radiotherapy/pelvic radiation after receiving berberine treatment. Berberine significantly reduced the incidence and severity of RIAIS and postponed the occurrence of RIAIS in patients with abdominal or whole pelvic radiation.

The objective of this exploratory, open-label, single-arm, phase II clinical trial was to evaluate plitidepsin (5 mg/m(2)) administered as a 3-hour continuous intravenous infusion every two weeks to patients with locally advanced/metastatic transitional cell carcinoma of the urothelium who relapsed/progressed after first-line chemotherapy. Treatment cycles were repeated for up to 12 cycles or until disease progression, unacceptable toxicity, patient refusal or treatment delay for >2 weeks. The primary efficacy endpoint was objective response rate according to RECIST. Secondary endpoints were the rate of SD lasting > or = 6 months and time-to-event variables. Toxicity was assessed using NCI-CTC v. 3.0. Twenty-one patients received 57 treatment cycles. No objective tumor responses occurred. SD lasting <6 months was observed in two of 18 evaluable patients. With a median follow-up of 4.6 months, the median PFR and the median OS were 1.4 months and 2.3 months, respectively. The most common AEs were mild to moderate nausea, fatigue, myalgia and anorexia. Anemia, lymphopenia, and increases in transaminases, alkaline phosphatase and creatinine were the most frequent laboratory abnormalities. No severe neutropenia occurred. Treatment was feasible and generally well tolerated in this patient population; however the lack of antitumor activity precludes further studies of plitidepsin in this setting.
