levoleucovorin and pirarubicin

A prospective phase II study was performed to determine the feasibility, efficacy and safety of arterial hepatic infusion (HAI) using pirarubicin combined with intravenous chemotherapy.. From December 1991 to April 1994, 75 patients with unresectable colorectal metastases confined to the liver were included in this multicenter study to receive intra-arterial hepatic pirarubicin and a systemic monthly regimen of 5-fluorouracil (5-FU) and folinic acid. Sixty-four patients were analyzed in the intention-to-treat analysis and 61 in the per-protocol analysis.. Tolerance of this regimen was rather good; however, functional catheter problems were observed in 29 patients (45%) resulting in failure of HAI in 21 cases (33%) after a median of three cycles; vomiting grade 3 was present in 12.5% of patients, neutropenia grade 4 in 23% and alopecia grade 3 in 19%. The overall response rate was 31.9% in intention-to-treat analysis, and 39.3% in per-protocol analysis. Extrahepatic progression was reported in only 21.7% of patients. Time to hepatic progression and extra-hepatic progression was 8.3 and 15 months, respectively, in intention-to-treat analysis, and 11 and 18 months, respectively, in per-protocol analysis. Median survival was 19 and 20 months in intention-to-treat analysis and per-protocol, respectively.. In our study, the combination of intra-arterial pirarubicin and intravenous chemotherapy demonstrated some efficacy and good tolerance in the treatment of isolated colorectal liver metastases. This treatment seems to prevent extra-hepatic spread and prolong survival time. The results of this study have to be confirmed by new trials using more active systemic chemotherapy.

The purpose of this study was to evaluate the tolerance and efficacy of combining i.v. irinotecan, 5-fluorouracil (5-FU) and leucovorin (LV) with hepatic arterial infusion (HAI) of pirarubicin in non-resectable liver metastases from colorectal cancer.. Thirty-one patients were included in a phase II trial with i.v. irinotecan/5-FU/LV administered every 2 weeks, combined with HAI pirarubicin 60 mg/m(2) on day 1 every 4 weeks. In most cases HAI was administered via a percutaneous catheter.. The main grade 3/4 toxicity was neutropenia, encountered in 78% of the patients. When all patients were considered in the analysis, tumour response rate was 15 out of 31 [48%; 95% confidence interval (CI) 32% to 65%]. Liver resection was made possible in 11 patients (35%; 95% CI 21% to 53%). There were no toxic death. Median overall survival was 20.5 months, and median progression-free survival was 9.1 months. In patients with completely resected metastases, median overall survival was not reached and median progression-free survival was 20.2 months.. The multimodality approach used in the present study was well-tolerated and yielded dramatic responses. An aggressive approach combining i.v. and HAI chemotherapy deserves further investigation.

A total of 50 patients were treated weekly with 5-fluorouracil (FU), leucovorin (LV), and 4'-O-tetrahydropyranyl-doxorubicin (THP) as first-line chemotherapy for advanced breast cancer (ABC). In phase I the doses of LV (500 mg/m2, day 1) and FU (350 mg/m2, day 1) were held constant, while the dose of THP (day 1) was escalated, from the initial dose of 10 mg/m2 up to the maximum tolerated dose (MTD). Twenty-eight patients entered phase I, and MTD for THP was defined as 35 mg/m2 in this combination. Dose-limiting toxicities were myelosuppression and hepatotoxicity. In phase II, another 22 patients were treated with THP at a dose level of 30 mg/m2. Including 4 patients already treated at this dose in the first part, 25 patients were evaluable for response: 1 patient obtained a complete response (CR) and 13 showed a partial response (PR), giving an objective response rate of 56%. The median duration of response was 9.1+ months and median survival, 15.5+ months. Side effects were generally mild, with ECOG grade I and II leukopenia in 51% of all cycles and grade III in 3% of the courses. Other toxicity included nausea and vomiting (54% and 8%, respectively) and alopecia (24%), all restricted to ECOG grade I and II. Our results suggest that weekly THP/LV-FU represents an active regimen for first-line treatment of ABC with relative low toxicity.

Previous clinical studies have suggested that 4'-O-tetrahydropyranyl-doxorubicin (THP) as well as 5-fluorouracil/high-dose folinic acid (5-FU/HDFA) are active and well-tolerated drugs in breast cancer treatment. This phase I-II study was designed to determine the maximum tolerated dose (MTD) of THP in combination with 5-FU/HDFA as a weekly schedule and to examine the activity and safety of this drug regimen in patients with advanced breast cancer. 5-FU and HDFA were set at doses of 350 mg/qm i.v. and 500 mg/qm i.v., respectively, whereas the THP dose has been escalated in increments of 5 mg/qm i.v. beginning at a dose level of 10 mg/qm until reaching of MTD in at least four patients in one dose level. For determination of MTD the first six cycles of each patient have been taken into account. Up to July 1990, 21 patients previously not treated with chemotherapy for metastatic breast cancer were entered into the study; the latest patient entered at 35 mg/qm THP dose level. A total of 270 cycles have been administered so far. Anemia and leukopenia was limited to ECOG grades I and II. Other toxicities were mild or moderate. No acute or subacute cardiotoxicity has been observed. Up to July 1990, MTD had not been reached. In the second part of the study, at least another 14 patients have to be entered in a dose level one below the MTD to evaluate the activity and safety of this regimen in a phase II trial.

Advanced pancreatic cancer is mainly treated by chemotherapy with poor prognosis. This study was designed to evaluate clinical efficacy and application of selective continuous transarterial infusion chemotherapy in treating patients with advanced pancreatic cancer.. Twenty patients with advanced pancreatic cancer were treated by selective continuous transarterial infusion chemotherapy. The interventional treatment was performed with Seldinger technique,12 patients received percutaneous femoral artery cannulization and catheter retention, 8 received percutaneous left subclavian artery port-catheter system implantation. Chemotheraputic drugs were continuously infused when the catheter was selectively placed in turner feeding artery. Nine patients were treated with pirarubicin (THP)/adriamycin (ADM) plus hydroxycamptothecin (HCPT),and 5-fluorouracil (5-FU)/calcium folinate (CF) regimen,and 11 were treated with gemcitabine (GEM) plus carboplatin (CBP),and 5-FU/CF regimen. Treatment regimens were repeated every 4-6 weeks with each cycle of 4 days. Tumor response rate,clinical benefit response (CBR),and survival time were observed.. Objective response rate was 10% with 1 case of complete remission (CR), and 1 case of partial remission (PR), CBR was 70% (14/20), 6-,and 9-month survival rates were 58.8%,and 39.2%. Median survival time for all patients was 8.8 months. No complication related to cannulization was found.. Selective continuous transarterial infusion chemotherapy is safe,and has good efficacy in treating patients with advanced pancreatic cancer, it may prolong survival time of patients.

The patient was a 71-year-old man who had been diagnosed as having a left renal pelvic cancer with liver metastasis. We performed total left nephroureterectomy with lymphnode cleaning and partial resection of the liver. Because abdominal CT 5 months after the operation revealed multiple metastasis of the liver, we performed chemotherapy with a regimen consisting of methotrexate 50 mg (intravenous injection), cisplatin 30 mg and pirarubicin 20 mg (intraarterial infusion), and leucovorin 3 mg (intramuscular injection), three times at intervals of 6 hours. Ten days after chemotherapy, CT revealed the disappearance of most of the liver metastatic lesions, and a partial response was obtained. We are now performing the regimen at an interval of a month to a month and one-half to control the metastatic lesions.

The role of biological response modifiers (BRM) in locoregional therapy for liver metastases of colorectal cancer was studied clinically and experimentally. Seven patients with numerous metastases to both lobes of liver were given intraarterial administration of BRM in combination with anticancer drugs. A partial response was observed in 1 patient. The response rate was 14.3%. Alternatively, intraarterial administration of both OK-432 and IL-2 into the rabbit with liver metastases of VX-2 tumors could bring about the infiltration of cytotoxic T lymphocytes around the tumors, followed by a significant decrease of the metastatic nodules. In addition, the same anti-tumor effect was observed when PSK was administered intraperitoneally into the BALB/c mouse with liver metastases of colon 26 tumors. Moreover, the therapeutic effect of water in oil type emulsion encapsulating both OK-432 and IL-2 was greater than that of the solution of BRM in BALB/c mouse with liver metastases of colon 26 tumors. These results indicated that BRM could be one of the promising agents in locoregional therapy against liver metastases of colorectal cancer.
