We have carried out a phase II study evaluating the activity of a 5-fluorouracil drug combination in patients with advanced non-small-cell lung cancer. Patients were given 60 mg/m2 of methotrexate i.v. on day 1. On day 2, 750 mg/m2 of 5-fluorouracil was administered as a 24-h infusion daily for 3 days. Also on day 3, 10 mg/m2 of mitomycin was given i.v. along with folinic acid. Folinic acid was started on day 3 initially at a dose of 25 mg/m2 intravenously every 6 h for three doses, followed by a 2-h infusion of 200 mg/m2 daily on days 3 and 4. Therapy was repeated every 28 days. Fourteen of 35 patients (40%) experienced a partial response to chemotherapy. The median survival of the entire group was 19 weeks. Mucositis was a common side effect but severe leukopenia, anemia, renal insufficiency, and skin ulceration were rare. This study demonstrated that 5-fluorouracil infusion therapy has activity in advanced non-small-cell lung cancer but the responses are not durable. Further studies evaluating differing dose schedules and alternate 5-fluorouracil infusion-based drug combinations seems warranted.

A phase II study to test the toxicity and the efficacy of a weekly combination of Mitoxantrone, 5-Fluorouracil and L-Leucovorin (MFL) was carried out in 43 patients with metastatic breast cancer. Chemotherapy consisted of mitoxantrone 4 mg/m2, 5-fluorouracil 375 mg/m2, and L-leucovorin 100 mg/m2 on day 1, weekly. Patient characteristics were: median age 53 years (range 36-65); estrogen receptor (ER) status was known in 26 patients and of these 15 (57.7%) patients were ER-positive and 11 (42.3%) ER-negative. Of the 43 patients, 25 (58.1%) and 18 (41.9%) patients had received prior adjuvant chemotherapy and prior adjuvant endocrine treatment, respectively. MFL was administered to 22 (51.1%) patients as first line chemotherapy for advanced disease, while 21 (48.9%) patients had received 1 to 2 cytotoxic regimens for metastatic disease. The dominant sites of metastases were: soft tissue in 11 (25.5%) patients, bone in 8 (18.6%) patients and viscera in 24 (55.9%). All patients were assessable for toxicity: only 8 patients experienced WHO grade 3 leukopenia. Thrombocytopenia, diarrhea, stomatitis, and nausea/vomiting were negligible. Anemia and alopecia were not observed. Thirty-nine patients were assessable for response: overall response rate was 28.2% (complete response 7.7% and partial response 20.5%). Median duration of response was 12 months (range 6-34). Patients with no prior anthracyclines had a 42.1% response rate compared to 15% in patients who had received anthracyclines. Median overall survival of the 43 patients was 6 months (range 1-34). Weekly MFL is a well-tolerated and a moderately effective regimen for the treatment of metastatic breast cancer.

Leucovorin, given usually by i.v. injection or orally changes to 5, 10-methylene tetrahydrofolate in tumor as well as normal cells. And in normal FdUMP, an active metabolite of 5-FU, binds tightly to thymidylate synthase in the presence of cofactor, 5, 10-methylene tetrahydrofolate. This interaction leads to potentiate the cytotoxic effect of 5-FU by prolonged inhibition of thymidylate synthase. Phase I study using l-leucovorin (l-LV), an active form of leucovorin, combined with 5-FU, was conducted. In the weekly schedule, 5-FU was fixed to 600mg/m2, and l-LV dose was escalated from 125 mg/m2 to 250mg/m2, if toxicity was acceptable. On the other hand, in the five consecutive-day schedule, 5-FU was fixed to 370mg/m2 and l-LV was escalated from 25mg/m2 to 50mg/m2, 100mg/m2 and 200 mg/m2. l-LV 10mg/m2 was tested as reference. On weekly schedule of l-LV 250mg/m2, grade III diarrhea was seen in 2 cases and grade IV leucopenia was seen in one. In five consecutive-day schedule, at each dose of l-LV, stomatitis, nausea plus vomiting, anorexia, anemia and leucopenia were seen. However, the increase of toxicities were not seen by dose escalation of l-LV. Then, we have been conducted a randomized early phase II study using 250 mg/m2 of l-LV weekly (arm A) and 100mg/m2 (arm B) or 10mg/m2 (arm C) of l-LV for 5 consecutive days in gastric and colorectal cancer by multicenter cooperative study. Plasma concentrations of l-LV were maintained > 10(-5) mol/L for over 5 hrs. after 2 hrs. infusion of 250 mg/m2 of l-LV and for over one hr. after a rapid injection of 100mg/m2 of l-LV.

Leucovorin (LV) enhances the activity of 5-fluorouracil (5FU). Based on these data, we performed a randomized trial with 5FU, epirubicin (EPI), mitomycin C(MMC) with/ without LV in advanced gastric cancer (AGC). The purpose of our study was to investigate if the addition of LV improved the response rate of the combination 5FU EPI, MMC (FEM) over FEM. From January 1988 until April 1994, 88 patients with recurrent or metastatic AGC were randomly received 5FU, EPI, MMC with (group A) or without (group B) LV. Between the two arms of the study no difference was noticed in sex, performance status, primary site of tumor, and lymph node metastases. Therapy included group A (5FU 600 mg/m2/day, i.v. bolus, on days 1, 8, 29, 36, and EPI 45 mg/m2/day, i.v. bolus, on days 1 and 29, MMC 10 mg/m2/day, i.v. bolus, on day 1) and group B (the same as group A plus LV 200 mg/m2/day by 2 h intravenous infusion with 5FU intravenous push at midinfusion). No significant difference in response rate was noticed between the two treatment arms; there were two (5%) patients with complete response in group A, and five (12%) in A and 11 (26%) partial responders in group B (p < 0.1). A significantly higher number of patients achieving stable disease was observed in group B; 19 (44%) in comparison to group A 10 (24%) (p < 0.048). There were more patients with progressive disease in group A 25 (59%) than in group B 12 (28%) (p < 0.003) (Table 2). No difference was noted in mean duration of response: group A, 15.8 (6-31) weeks; and group B, 17.6 (6-28) weeks. The mean time to progression was for group A [11.4 (6-35) weeks] and for group B [17.6 (8-33) weeks]. Mean survival was for group A [27.4 (12-59) weeks] and for group B [30.6 (17-53) weeks], for 50% of patients. Causes of death were, for group A, 40 patients from disease progression and two sudden deaths; for group B, causes of death were for 41 patients disease progression and two sudden deaths. There were two patients in group A and one in group B that were not evaluable because they abandoned therapy after the first cycle. Toxicity was increased in group B; anemia, nausea and vomiting, and alopecia (p < 0.055) were more severe in group B, but not statistically different when compared to group A. Neutropenia, thrombocytopenia, mucositis, and fatigue of any grade were significantly more common and severe in group B. Significant dose reductions due to toxicity were required more commonly in group B. We conclude that the response rate was increased in the schedule with the addition of LV, at the cost of increased toxicity and with no difference in survival. A randomized trial comparing FEM-LV with new generation regimens would determine whether the addition of LV qualifies FAM equally active with these.

A 54-year-old patient with primary cerebral lymphoma was treated with two 4-weekly cycles of high-dose intravenous cytarabine (12 g/m2) and methotrexate (3 g/m2). The administration of the first course proceeded without notable complications. Before the administration of methotrexate in the second cycle blood cell counts and chemistry showed no abnormalities except for slightly increased alkaline phosphatase and gamma-glutamyl-transpeptidase levels which was attributed to diphantoin comedication. The patient developed symptoms of acute renal failure 7 h after methotrexate infusion which resulted in a very high serum methotrexate level (39.84 micromol/l) at 20 h after infusion. Rescue therapy was intensified: the leucovorin dosage was increased (1,200 mg continuous i.v. infusion every 24 h) and combined with thymidine rescue therapy (8 g/m2 per day continuous i.v. infusion every 24 h). Urine alkalinization was increased and diphantoin therapy was stopped. Leucovorin eye drops and mouth washes were started 5 days after methotrexate administration to prevent conjunctivitis and mucositis as a result of high methotrexate levels (>2.4 micromol/l). In spite of the fact that serum methotrexate levels remained persistently higher than 0.1 micromol/l for 12 days, the patient experienced no further short-term systemic toxicity except for anaemia (grade 3 according to NCI Common Toxicity Criteria). After day 12 intensified rescue therapy and the frequency of alkalinization were decreased to standard procedures and stopped on day 19. It is concluded that i.v. administration with high-dose methotrexate can result in unpredictable acute toxicity. In our patient, acute methotrexate toxicity was treated successfully by intensification of classical leucovorin rescue therapy in combination with thymidine infusion. In addition, leucovorin mouth washes and eye drops may have prevented mucositis and conjunctivitis, respectively.

We report a case in which weekly paclitaxel (TXL) administration was effective for gastric cancer with malignant ascites. TXL (80 mg/m2) was infused over 1 hour after short premedication on an outpatient basis. Administration was continued for 3 weeks followed by 1 week rest. The patient was a 49-year-old woman who suffered from non-resectable gastric cancer, staged intraoperatively as having severe lymph node metastasis and malignant ascites. As an outpatient treatment, she was first treated with 5-fluorouracil combined with high-dose Leucovorin for 4 cycles. However, she complained of abdominal fullness and ascites, and received weekly TXL administration as the second line treatment. The ascites had completely disappeared 3 months after administration. The toxic events were anemia (grade 1) and alopecia (grade 2). No major adverse effects such as hypersensitivity reaction, leukopenia or peripheral neuropathy were observed.

Two phase III studies revealed an oral UFT/Leucovorin (LV) regimen, in which the drugs are taken for 28 consecutive days every 35 days, which proved to be equivalent to an infusional 5-fluorouracil/LV regimen for metastatic colorectal cancer (CRC). The weekday-on/weekend-off schedule for UFT, which is taken for 5 consecutive days followed by 2 drug-free days,has been reported to be safe and to have good feasibility. In the present study, we investigated the weekday-on/weekend-off schedule for UFT/LV in 54 patients with CRC. The median administration period was 8 months. Ten patients (19%) showed grade 2 or more severe adverse reactions. One of them had grade 3 diarrhea and anorexia. Grade 2 anemia was observed in 9 cases (19%) and grade 2 leucopenia was in 2 cases (4%). Myelotoxicity was mild. These results suggested that the adverse reactions in the weekday-on/weekend-off schedule for UFT/LV are less severe than the conventional UFT/LV schedule reported previously. Antitumor effects and survival benefits of the two schedules should be evaluated by a phase III study.

The patient was a 75-year-old man who was admitted because of diarrhea and anemia. Endoscopic examination revealed advanced sigmoid colon cancer. Serum CEA levels were markedly elevated. In July 2007, surgery was performed, but the sigmoid colon cancer was unresectable. After surgery, the patient was treated with chemotherapy and concurrent radiotherapy. The chemotherapy consisted of oral UFT (420 mg/body/day)and Leucovorin (75 mg/body/day) administered for 6 weeks. Radiotherapy at 2 Gy/day was administered 30 times (total dose 60 Gy). The tumor decreased slightly in size and serum CEA levels also decreased. The patient refused surgery as an additional therapy. In August 2007, we started combination chemotherapy using oral S-1 (100 mg/body/day, day 1-14) and intravenous CPT-11 (140 mg/body/day, day 1 and 15) as one course for 4 weeks. After 4 courses, serum CEA levels were normal, the sigmoid colon cancer was not found by endoscopy and a biopsy specimen revealed no malignant cells. Moreover, after 8 courses, the tumor disappeared, as confirmed by computed tomography (CT) and positron emission tomography-CT, representing a complete response. Chemoradiotherapy using UFT and Leucovorin, and chemotherapy consisting of S-1 and CPT-11 as an additional therapy may be effective for treating unresectable advanced sigmoid colon cancer.

A 65-year-old woman was referred to our hospital for examination of anemia. Colonoscopy showed a type 1 tumor in the ascending colon with nearly complete stenosis that was diagnosed as a tubular adenocarcinoma. Computed tomography (CT) revealed swelling of the regional, periaortic, and celiac lymph nodes and lymphangitis carcinomatosa. The patient was diagnosed as having Stage IV ascending colon cancer, and neoadjuvant chemotherapy was administered to avoid non-curative resection. The patient was treated with cetuximab and oxaliplatin, Leucovorin, and 5-fluorouracil( mFOLFOX6) combination chemotherapy. After 6 courses of chemotherapy, the primary lesion and multiple lymph node swellings greatly reduced in size and lymphangitis carcinomatosa improved. Accordingly, right colectomy with D3 nodal dissection was performed. The patient was recurrence free at her 8-month follow-up examination. Neoadjuvant chemotherapy with molecular targeted drugs is useful in the treatment of patients with unresectable primary cancer.

A 71-year-old man presented with sigmoid colon cancer and multiple unresectable liver metastases. As the sigmoid colon cancer caused anemia, we performed laparoscopic-assisted sigmoidectomy prior to the administration of systemic chemotherapy. Bevacizumab (Bv) plus modified Leucovorin, 5-fluorouracil, and oxaliplatin (mFOLFOX6) was administered as first line therapy.At 3 months from the start of chemotherapy, computed tomography revealed that the size of the liver metastases reduced by 49.45%, as evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST) guidelines (version 1.1). The only adverse event observed was Grade 1 peripheral neuropathy after the eighth dose of oxaliplatin.As the progression of peripheral neuropathy was observed at the ninth dose of oxaliplatin, oxaliplatin was omitted from further therapy; the patient was converted to maintenance therapy with simplified biweekly Leucovorin and fluorouracil (sLV5FU2). Bv plus mFOLFOX6 followed by sLV5FU2 for first-line therapy was effective for disease management over 23 months, but a partial response (PR) was the best overall response achieved.
