For patients with advanced, unresectable head and neck (HN) cancer, surgery and/or radiotherapy are the standard treatments but have poor results. A phase II trial of a continuous infusion of cisplatin, 5-FU, and high dose folinic acid (PFL) as induction chemotherapy in patients with previously untreated, locally advanced HN cancer was performed in an attempt to confirm the encouraging results reported by Dana Farber investigators using an identical regimen. Forty-five consecutive patients with unresectable HN cancer were treated every 28 days with a continuous infusion of cisplatin 25 mg/m(2)/day (days 1-5), 5-FU 800 mg/m(2)/day (days 2-6), and folinic acid 500 mg/m(2)/day (days 1-6). After three courses of chemotherapy, patients were treated with surgery and/or radiotherapy. Objective responses were observed in 26 of 38(69%) evaluable patients with 14(37%) clinical complete responses. Grade III-IV toxicity was important and consisted mainly of mucositis and neutropenia that were found in 47 and 18%, respectively , of patients after the first course. There was one toxic death. PFL is an active, toxic induction regimen for far-advanced HN cancer, yielding a response rate in the range of the widely used cisplatin and 5-FU (PF) schedule; a comparative trial is warranted before concluding that PFL is superior to the latter combination.

A randomized comparative study of surgical adjuvant chemotherapy using dl-leucovorin (dl-LV) and 5-fluorouracil (5-FU) (FL-therapy) with CDDP, 5-FU, and dl-LV (PFL-therapy) was conducted. The following were the administration schedules: Arm A was 13 mg/m2 of CDDP, 300 mg/m2 of 5-FU, and 30 mg/body of dl-LV for 5 consecutive days and arm B was 300 mg/m2 of 5-FU and 30 mg/body of dl-LV for 5 consecutive days. Both regimens were followed by biweekly administration of the same dose of dl-LV and 5-FU in outpatients. Arm A was started at the 26th postoperative day and arm B at the 21st day on average. Some 26 cases composed of 11 cases of arm A and 15 cases of arm B completed the administration schedules. Only one case in arm A was complicated by local recurrence around 35 months after operation. Major toxicities were anorexia and neutropenia. Both toxicities were seen more in arm A than in arm B, showing complete recovery in all cases. These data suggest that PFL-therapy and FL-therapy seem to be possible and promising surgical adjuvant therapies for advanced colorectal carcinoma.

In order to optimize the therapeutic index of combining etoposide, epirubicin, cisplatin, 5-fluorouracil (5-FU), leucovorin (EEPFL) chemotherapy in the treatment of advanced gastric cancer, a trial of a novel schedule of weekly administration was conducted. Weekly EEPFL treatment consisted of a concomitant boost of etoposide 40 mg m(-2) i.v. over 30 min, epirubicin 10 mg m(-2) i.v. over 5 min to a backbone regimen, weekly PFL chemotherapy with cisplatin 25 mg m(-2), 5-FU 2200 mg m(-2), leucovorin 120 mg m(-2) given simultaneously by 24-h i.v. infusion. Response, survival and toxicity were evaluated. Forty-two patients were studied. Median age was 69 (range 31-84) years. Twenty-six per cent of patients showed complete response and 45% partial response. The overall response rate was 71% (95% confidence interval 58-84%). For a total of 507 weekly EEPFL cycles delivered, the incidence of grade 4 leucopenia was 1% of cycles. One patient died of neutropenia septicaemia. There was no other grade 4 toxicity. Grade 3 and 2 leucopenia occurred in 7% and 14% of cycles. The incidence of grade 3 and 2 mucositis was 1% and 3% of cycles. Grade 3 and 2 diarrhoea occurred in 0.4% and 1.6% of cycles. Overall median survival was 10 months (range 3-41+ months). Weekly EEPFL chemotherapy is an effective regimen with tolerable toxicities in the treatment of advanced gastric cancer. A randomized controlled clinical trial to formally assess the efficacy and benefit of EEPFL chemotherapy is under way.

The purpose of the study was to assess response rate, clinical outcome, organ/function preservation and toxicity in head and neck cancer patients treated with induction chemotherapy followed by concomitant chemoradiotherapy and, when necessary, limited surgery. The study design was a phase II non-randomized trial in hospitalized patients setting. The treatment plan consisted of 3 cycles of induction chemotherapy with cisplatin, fluorouracil (5-FU), l-leucovorin and interferon alpha2b (PFL-IFN) followed by 7 cycles of 5-FU, hydroxyurea and concomitant radiation for 5 days (FHX) for a total radiation dose of 70 Gy. 13 Cis-retinoic acid was added to treatment regimen for chemoprevention and a systematic prophylaxis of mucositis was administered to all patients during FHX. Conservative surgical resection was reserved to patients with no optimal response (PR > or =70%), whereas radical surgery was performed as salvage treatment. Twenty-six patients were treated at one institution: more than 90% had stage IV disease and only 19.2% had laryngeal cancer. Eighty-one percent of patients had performance status 0 and 23.1% of patients had >5% weight loss at the start of treatment. Nineteen patients were analyzed for response to PFL-IFN: 3/19 (15.8%) patients achieved a CR and 7/19 (36.8%) achieved a PR for an ORR of 52.6%. FHX was administered on protocol to 12 patients: 6 patients (50%) had CR, 1 patient (8.3%) had PR for an ORR of 58.3%, 2 patients (16.7%) had SD and 3 patients (25%) had PD. At the completion of FHX, no patient underwent local therapy according to treatment plan. At a median follow-up time of 13.5 months (range 1-28+) at June 2001, among 26 patients enrolled 12 (46.1%) were still alive and 9 (75%) of them were progression-free. The median duration of response was 9 months (range 0-25+), the median progression-free survival was 10.5 months (range 0-28+), the median overall survival time was 9 months (range 1-22). The toxicity was significant and consisted mainly of mucositis and, to a lesser extent, neutropenia/thrombocytopenia. In the present study, the low serum levels of leptin and the high serum levels of proinflammatory cytokines in advanced stage cancer patients were confirmed. In conclusion, this sequential induction chemotherapy and chemoradiotherapy program has been found moderately active and significantly toxic; moreover, the long overall treatment duration must be taken into consideration. For these reasons, this regimen could not be recommended for a phase III randomized study.

Biochemical modulation of 5-fluorouracil (5-FU) has been verified the evidence of significant improvement of survival and quality of life in patients with advanced colorectal carcinoma. We investigated the therapeutic and adverse drug reaction of intensive chemotherapy using cisplatin (CDDP), 5-FU and dl-leucovorin (LV) (PFL-therapy), which may be producing dual biochemical modulation effect of 5-FU for advanced colorectal carcinoma. Administration schedule was 13 mg/m2 of CDDP, 300 mg/m2 of 5-FU, and 30 mg/body of dl-LV for 5 consecutive days. This regimen was repeated at 3-week intervals in hospital. Sixteen patients were enrolled in this study, most of whom had a history of previous chemotherapy as adjuvant treatment, and the response rate was 25%, with four patients having "partial response" and eight "no change". In respect to performance status, 46% of patients who completed the protocol were markedly improved in spite of their poor performance status before treatment. Moreover, when patients were classified into two groups based on changes of the serum level of CEA, "responder in CEA level" showed better prognosis than "non-responder in CEA level". Major toxicities were nausea, hyperglycemia and neutropenia. Three patients experienced Grade 4 hematological side effect, but these complications resolved quickly in all patients except for one patient. PFL-therapy is effective for advanced colorectal cancer with large tumor burden and showed the same prognostic result as the American and European trials in spite of smaller number of treatment cycles and a history of previous chemotherapy. We will be able to demonstrate the usefulness of this regimen for Japanese patients with advanced colorectal cancers after adding new cases to the present report.
