RESUMO

PURPOSE: To evaluate the response rate and the immunorestorative properties of subcutaneously administered interferon alfa-2b (IFN-A2b) in patients with advanced renal cell carcinoma (RCC) and to correlate the immune status with the clinical responses. PATIENTS AND METHODS: Twenty-six patients with advanced RCC were treated with recombinant IFN-A2b. The dose was increased progressively from 5 x 10(6) IU the first week to 10 x 10(6) IU the second week, and thereafter to 15 x 10(6) IU subcutaneously. RESULTS: Four patients (15%) achieved partial responses (PRs), and five patients (19%) had stable disease (S), whereas 17 patients (65%) progressed. In all patients, blood was withdrawn before IFN treatment and monthly thereafter. T lymphocytes after isolation from peripheral blood were tested for proliferation in the autologous mixed lymphocyte reaction (autoMLR) and allogeneic mixed lymphocyte reaction (alloMLR), interleukin-2 (IL-2) production, expression of IL-2 receptors during the alloMLR, and the production of interleukin-1 (IL-1) by peripheral-blood monocytes. Twelve patients were assessable, four patients had a PR, one patient had S, and seven patients had progressive disease. Striking increases were demonstrated in all parameters 1 month after treatment with IFN-A2b in the four patients who responded and the patient with S. Namely, the autoMLR responses showed a mean increase of 250%, the IL-2 production 247%, the expression of IL-2-specific receptors 446%, the alloMLR responses 160%, and the production of IL-1 262%. On the contrary, the nonresponders did not show any change in their overall immune status, and in some, deterioration of the already depressed immunologic functions was observed. CONCLUSIONS: Administration of IFN-A2b results in a marked potentiation of deficient cellular immune response in vitro in those patients with RCC who respond to the treatment. This may have prognostic significance, and certainly more patients are required to be studied for definite conclusions.

RESUMO

BACKGROUND: Partial splenectomy is considered to be the optimal management for a variety of diseases. At the same time, laparoscopic procedures are increasingly used because they present certain advantages against their open counterparts. In this study, the safety and efficacy of radiofrequency ablation (RFA) were evaluated in laparoscopic partial splenectomy performed in a pig model. METHODS: Eight domestic pigs were used. Four abdominal trocars were inserted under general anesthesia and the spleen was stabilized with laparoscopic clamps. A RFA needle electrode was inserted transcutaneously, and coagulative necrosis of a zone of the splenic parenchyma between the body and the lower pole was performed. Bloodless sharp division and removal of the lower pole followed. After 0, 7, 30, or 120 days, the animals were killed and examined. RESULTS: Blood loss and operation time were minimal. Mortality and morbidity were zero. No abnormal findings were encountered during the postmortem abdominal exploration. CONCLUSION: This study demonstrates the feasibility, safety, and efficacy of laparoscopic RFA-assisted partial splenectomy. The RFA-assisted laparoscopic partial splenectomy adds a novel technique to the surgeon's armamentarium for the preservation of a part of the spleen.

RESUMO

The outcome of treatment of advanced renal cell carcinoma is disappointing. In interferon (IFN)-treated patients, the high incidence of adverse effects causes many patients to withdraw from treatment. This 12-week randomized study compared the incidence of toxicity associated with high-dose IFN monotherapy (15 x 10(6) U thrice weekly) and treatment with the combination of low-dose IFN (5 x 10(6) U thrice weekly) and 6 mg/m2 vinblastine (VBL) every 14 days in 100 consecutive patients. There was no significant difference in response rate between treatment arms (42% IFN vs. 34% IFN + VBL) or between subgroups (by tumor location). Combined treatment was associated with a significantly lower incidence of fever, fatigue, and weight loss but with a higher incidence of leukopenia. There was no significant difference in the incidence of other events. More patients treated with IFN monotherapy required bed rest, and overall treatment costs were 60% higher than for combined treatment. It is concluded that combined treatment with low-dose IFN and VBL, without loss of short-term efficacy, is better tolerated and less expensive than high-dose IFN monotherapy.

RESUMO

51 patients with stage IIIB and IV breast cancer entered a prospective phase II study of combination chemotherapy that consisted of mitoxantrone (8 mg/m2) day 1, methotrexate (25 mg/m2) day 1, vincristine (1 mg/m2) day 2 and carboplatin (250 mg/m2) day 2 (MIMOC) given in a 3-weekly schedule. None had received prior chemotherapy for metastatic disease, although 16 patients were given adjuvant chemotherapy. Objective response to treatment was seen in 29 of 48 patients analysed for response (60%) with 8 complete responses (CR). 7 out of 8 patients with stage IIIB disease responded, 2 of them completely. Responses were seen in all sites but the best results were achieved in lung metastases with 50% CR. The median duration of response was 8 months and the median time to disease progression was 12 months. The main toxicity was nausea and vomiting which was severe in 20% of the patients. Other toxicities were mild. MIMOC was administered on an out-patient basis and appears to be effective as first-line treatment in advanced breast cancer.

RESUMO

We performed a phase II study to evaluate the activity and toxicity of the combination of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and carboplatin as first-line treatment in patients with recurrent or metastatic head and neck cancer. From March 1994 until August 1996, 49 patients were treated with paclitaxel 200 mg/m2 by 3-hour infusion followed by carboplatin at an area under the concentration-time curve of 7 mg/mL x min; treatment was requested every 4 weeks. Granulocyte colony-stimulating factor was administered prophylactically on days 2 to 12 of each cycle. The study included 41 men and eight women, with a median age of 57 years (range, 23 to 73 years). Most of the patients were symptomatic and had locoregional disease. Primary sites included nasopharynx (14 patients), oropharynx (six), oral cavity (four), hypopharynx (three), larynx (20), paranasal sinuses (one), and unknown (one). After the completion of treatment, four patients (8%; 95% confidence interval, 0% to 16%) achieved a complete response and 12 (24%; 95% confidence interval, 12% to 37%) achieved a partial response. Grade 3/4 toxicities included anemia (2%) and leukopenia, thrombocytopenia, nausea/vomiting, diarrhea, and stomatitis (4% each). After a median follow-up of 15.3 months, median time to progression was 5.7 months (range, 0.5 to 29.8+ months) and median survival was 13.3 months (range, 0.5 to 30.2+ months). In our ongoing study in a similar patient population, gemcitabine was substituted for carboplatin.

RESUMO

From June 1985 to March 1993, 20 consecutive patients with histologically proven malignant mesothelioma were treated with cisplatin 100 mg/m2 i.v. infusion on day 1 and vinblastine 6 mg/m2 i.v. on day 1 and 8. Treatment was repeated every 4 weeks until progression. All patients were evaluated clinically and by CT-scan and were staged (Stage IV), according to Butchard's criteria, on entry to the study. None had prior surgical excision. Eighty-one chemotherapy cycles were administered to 20 patients. One complete response, four partial responses, nine stable diseases and six progressions were noted. One partial responder entered complete response following an operation. Toxicity was acceptable and no treatment-related deaths occurred. The median survival for responders was 19.3 months; for patients with stable disease 15.7 months and for non-responders, 5.2 months. The mean duration of response was 13 months. We conclude that for this small group of patients, the combination cisplatin-vinblastine is effective, with acceptable toxicity in malignant mesothelioma. Further study with a larger number of patients is necessary.

RESUMO

Recent advances in biochemical pharmacology have revealed the basis for the biological modulation of 5-fluorouracil (5-FU) by methotrexate (MTX) and folinic acid (FA). Sequential use of MTX given 24 h prior to 5-FU has resulted in enhanced cell kill in vitro and in vivo. In addition, administration of FA prior to 5-FU has led to potentiation of 5-FU action by stabilization of the ternary complex of thymidine synthase. In the present randomized study, two groups of patients with advanced colorectal cancer were treated as follows: 43 patients (pts) in group A received 5-FU + FA, whereas 45 pts in group B received 5-FU + FA + MTX. The dosage was as follows: group A received FA i.v. at 300 mg/m2 per day, prior to i.v. 5-FU at 500 mg/m2 per day on days 1-4; group B was given MTX i.v. at 130 mg/m2 per day on day 0, followed 24 h later by FA at 15 mg q6h x 6, and 5-FU + FA was started on day 1 and given at the same doses and schedule described for group A. Objective responses were achieved by 8/43 pts in group A (1 complete response and 7 partial responses) and by 18/45 pts in group B (3 complete and 15 partial responses), all occurring in the liver. There was no significant difference in the median time to progression (group A 6.1 months, group B 6.8 months) or the median survival (group A 9.2 months, group B 10.3 months). Toxicity was significantly greater in group B [grade 2-3 mucositis 20% versus only 2% in group A (P < 0.0001); grade 3 diarrhea in group B 15% versus 3% in group A (P < 0.001)]. According to our results, double biological modulation of 5-FU with MTX + FA led to an enhanced response rate with increased toxicity as compared with the 5-FU + FA regimen given at less than its maximally tolerated dose.

RESUMO

We compared the antiemetic efficacy of ondansentron versus ondansentron and corticosteroids in cisplatin-induced emesis. None of our patients had received prior chemotherapy. All patients received chemotherapy including cisplatin 100 mg/m2. Forty patients received ondansentron alone (Group A) and 40 the combination of ondansentron and methylprednisolone (Group B). Ondansentron was given at a dose of 8 mg in 100 mL N/S over 10 min by intravenous infusion. The initial dose was administered before the cisplatin and was followed by 8 mg orally in the afternoon and before sleeping the first day of chemotherapy. During the next 2 days, the patients received 8 mg orally 3 times daily. Methylprednisolone was given as an intravenous bolus of 40 mg before chemotherapy and then together with each dose of ondansentron at a dose of 16 mg orally. Group A had significantly longer duration of nausea after chemotherapy than group B (117 +/- 111 min, 62 +/- 71 min, P < 0.013). The response on emesis was also improved in group B, especially the day of chemotherapy [treatment failure: group A: 13 patients (30%) versus group B: 5 patients (11.6%), P < 0.03] and the next day [complete response: group A: 17 patients (39.5%) versus group B: 30 patients (69.7%), P < 0.005]. Patients in group B presented more sedative effects (P < 0.001) and better appetite (P < 0.02) than patients in group A. There were no other significant differences in side effects (activity, headache, constipation, etc). We conclude that corticosteroids improve the antiemetic efficacy of ondansentron in cisplatin-induced chemotherapy, and should be included in antiemetic regimens.

RESUMO

Some clinical parameters play a role in developing effective antiemetic therapy. In the present study, 310 patients entered and 301 were evaluable. They received cisplatin based combination chemotherapy (100 mg/m2), with antiemetic therapy based in metoclopramide, at a standard dose and schedule (2 mg/kg in 5 doses). Patient characteristics such as age, sex, performance status (Karnofsky), site of primary tumor, weight loss >15%, previous chemotherapy, previous radiotherapy, history of vomiting during pregnancy, additional drugs (dexamethasone, alprazolam), in the antiemetic regimen were included in the evaluation. We also studied the manifestation of anxiety and depression and the presence of psychosocial problems related to therapy, evaluated them with specific psychological indexes modified for our study. We evaluated incidence of vomiting, retches, and nausea, with several scales. We distinguished three groups of factors influencing nausea and vomiting. Factors that predicted for increased nausea and vomiting was gender (women), stress and age (younger patients experienced more prolonged duration and higher grades of nausea). The addition of alprazolam (a sedative drug) and dexamethasone, was associated with decreased incidence of nausea and vomiting. The weight loss (increased nausea and decreased vomiting control according to Gralla's scale). Previous chemotherapy decreased the number of patients without nausea and vomiting control according to Gralla's scale. Patients with previous radiotherapy presented an increased grade of nausea. Patients with head and neck cancer presented less nausea with shorter duration, less frequent episodes of vomiting. Patients with ovarian cancer presented increased mean number of retches. In conclusion, despite difficulties in assessing nausea and vomiting among clinical trials, several factors, especially stress, gender, weight loss, additional drugs (corticosteroids and sedatives) may play an important role in modulating the antiemetic response.

RESUMO

Some factors have demonstrated an influence on emesis and antiemetic response. In order to study these factors, 306 patients (pts) entered this study receiving cisplatin based combination chemotherapy (CT) (100 mg/m3, with ondansetron (8 mg, 3 times daily for 4 days) as the only antiemetic treatment. Known factors that influence the result of antiemetic therapy such as age, sex, performance status (Karnofsky), site of primary tumor, weight loss, anxiety, depression, psychological problems related to CT (psychological PRC) etc, were included in the evaluation. We evaluated the number of vomits, retches and nausea. The existence of psychological PRC was found to be a prominent factor for the development of nausea and emesis, being at the same time strongly associated with scaling variables (Gralla, retching and nausea grading) used to measure the severity of nausea and emesis (p = 0.001). Stress was also a significant predictor; patients with stress had an almost two times higher probability to develop nausea or retching compared to patients without stress indications (p = 0.001), while the occurrence of retching was marginal. Younger patients (less than 40 years old) were found to be almost three times more susceptible to retching compared to older patients (more than 40 years old) (P 0.006). With all possible evaluations, we concluded that significant factors are psychological PRC, stress and age. In conclusion, three factors, age, stress and psychological PRC, should be taken seriously into consideration in the design of future trials evaluating antiemetic treatment, as well as in the every-day clinical practice, in order to provide patients with a better quality of life during emetogenic CT.

RESUMO

The identification of prognostic factors influencing local control and survival of patients with nasopharyngeal cancer (NPC) might help in pointing out those patients who would probably benefit from primary treatment. A series of 137 Greek patients with locally advanced NPC treated with chemotherapy and/or radiation were analyzed for significant prognostic factors influencing complete response (CR) to treatment, time to progression (TTP) and overall survival (OS). After the completion of treatment, 92 (67%) patients achieved CR. Logistic regression analysis revealed that only T classification was significant for CR (p = 0.0058). After a median follow-up of 5 years, 66 (48%) patients demonstrated tumor progression and 64 (47%) died. Median TTP was 25.8 months (range, 0.3-118+) and median survival 58.3 months (range, 0.3-124+). Cox proportional hazards model identified age (p = 0.024) and T classification (p = 0.009) as significant factors for TTP. These two factors were also found to be significant for OS (p = 0.005 and p = 0.013, respectively). The present study has shown that major prognostic factors influencing the outcome of our patients with NPC are similar to those reported in recent Chinese studies. These prognostic factors may be used as stratification factors in randomized clinical trials.

RESUMO

The purpose of our study was to evaluate the effectiveness of alprazolam (APZ) as an adjuvant drug to ondansentron against cisplatin-induced emesis. All patients received CDDP 100 mg/m2, and had previously received chemotherapy. We established two groups of patients randomly: Group A patients received 5-HT3 alone, and Group B received 5-HT3 and APZ. The drugs were administered as follows: 5-HT3 was given at a dose of 1 ampule 8 mg in 100 ml N/S in 10 minutes i.v. infusion before the infusion of CDDP. We continued with 1 tablet 8 mg in the afternoon and 1 before sleeping the first day; for the next two days, patients received 3 tablets 8 mg/day. APZ was given in tablets of 0.25 mg 60 minutes before CDDP infusion and then with the second and third dose of 5-HT3. We did not find significant differences in clinical parameters and factors, especially anxiety, that influenced vomiting between the examined groups. The mean number of vomiting episodes without gastric content (4.76 episodes) and the mean duration of nausea (195 minutes), were greater in Group A than in Group B (1.39 episodes, p < .0001; 91 minutes, p < .049). Differences also were found in the mean number of vomiting episodes with gastric content between the examined groups (A: 1.97; B: 1.09; p < .135). The intense of nausea and vomiting according to WHO classification was greater in Group A (grade 0, p < .004; grade 2, p < .020) than in Group B. Patients of Group B had fewer problems with appetite (p < .027), and more intense sedative effect (grade 0 [p < .001], 1 [0.027], 2 [0.022]) than patients of Group A. In conclusion APZ improved the antiemetic efficacy of ondansentron in cisplatin-induced emesis.

RESUMO

Thirty patients with advanced bladder cancer received combination chemotherapy with cis-platinum, adriamycin and mitomycin C. Two patients (6.6%) responded completely and survived 24 and 30 months. Partial response was noted in 14 patients (46.6%) who had a median survival of 9.6 months. Eight patients (26.6%) had stable disease with a median survival of 5 months whereas in 6 patients (20%) their disease progressed with a median survival of 3 months. The amelioration of hematuria, regardless of response, was impressive. Nausea and vomiting were the commonest side effects. Myelotoxicity was mild and reversible. We conclude that PAM chemotherapy is effective and well tolerated in patients with advanced bladder cancer.

RESUMO

BACKGROUND AND AIM: Co-existence of intra-abdominal non-vascular disease with an abdominal aortic aneurysm (AAA) poses a difficult surgical challenge. MATERIAL AND METHODS: Review of hospital records of 602 patients undergoing elective surgery for AAA during a 9-year period identified 61 (10.3%) patients with a co-existent intra-abdominal non-vascular disease requiring surgery. RESULTS: The concomitant operations were 26 cholecystectomies, 11 inguinal hernia repairs, 2 small bowel resections, 5 left and 5 right hemicolectomies and 1 low anterior resection for colorectal carcinoma, 1 gastrectomy for gastric carcinoma, 5 nephrectomies, one salvage cystectomy for renal carcinoma and 1 left liver lobectomy for hepatrocellular carcinoma. Additional procedures for benign diseases prolonged the operative time by a mean of 35 (range 20-105) minutes and the major operations for malignancy by 120 (range 60-225) minutes. The overall hospital mortality and morbidity rates in the whole series of AAA (n = 602) remained as low as 0.66% and 13.6% respectively. There was no mortality and only two complications occurred in patients undergoing the combined procedure (n = 61). During a follow up period of 4-70 months, no graft infections were detected. CONCLUSION: In selected patients, the one stage approach is safe and effective. Attention should be given to the technical details and the rules of antisepsis. In elderly patients with AAA, a co-existent malignancy should be actively excluded.

BACKGROUND: Irinotecan (IRI) and oxaliplatin (OXA) are effective in the treatment of colorectal cancer. Previously untreated patients with advanced colorectal carcinoma (CRC) were randomly assigned to receive IRI plus leucovorin (LV)/5-fluorouracil (5-FU), or OXA plus LV/5-FU in order to compare the response rates, time-to-tumor progression, overall survival rates, and toxicity profiles of these two agents. MATERIALS AND METHODS: From January 1999 to February 2002, 295 patients were randomized to receive either IRI/LV/5-FU or OXA/LV/5-FU. The treatment schedules consisted of weekly IRI 70 mg/m(2) or OXA 45 mg/m(2) plus LV 200 mg/m(2) followed immediately by intravenous bolus 5-FU 450 mg/m(2) for 6 weeks, followed by a 2-week rest period. Treatment was continued for up to four cycles or until disease progression, unacceptable toxicity or patient refusal. RESULTS: There were no significant differences between the study arms in the overall response rate (33% with IRI/LV/5-FU versus 32% with OXA/LV/5-FU based on responses demonstrated on a single evaluation; 23% with IRI/LV/5-FU versus 22.3% with OXA/LV/5-FU based on responses confirmed according to WHO criteria) median time to progression (8.9 versus 7.6 months), and median overall survival (17.6 versus 17.4 months). Toxicity profiles (grades 3 and 4) were similar in the IRI and OXA arms (diarrhea 12.3% and 9.8%, neutropenia 8.2% and 4.9%, and febrile neutropenia 1.4% and 1.4%, respectively), with the exception of grade 3 sensory neuropathy, which almost exclusively occurred in the OXA arm (0% versus 5.6%; P=0.003, Fisher's exact test). CONCLUSION: The IRI/LV/5-FU and OXA/LV/5-FU regimens demonstrated equally substantial efficacies and manageable toxicity profiles in the first-line treatment of patients with advanced CRC. However, IRI/LV/5-FU may be the preferable regimen to avoid significant neurotoxicity associated with OXA-LV/5-FU.

RESUMO

Forty-one patients with advanced renal cell cancer started treatment with recombinant alpha-interferon intramuscularly, beginning at a dose of 5 x 10(6) U x 3/week, progressively increasing doses every week, from 5 x 10(6) U x 3/week to 10 x 10(6) U x 3/week, to the highest dose of 15 x 10(6) U x 3/week. No complete response was achieved, partial response was achieved in 6 (13%) patients with a median duration of 45.2 (13-134) weeks. The majority of side effects from interferon treatment evaluated according to WHO classification were seen during the first 2 months and they were fever (after interferon administration) in 95% patients, chills (51%), flu like syndrome (65%), fatigue (87%), anorexia (80%), worsening in performance status (56%), nausea and vomiting (19%), weight loss (> 10% during therapy) (26%), leukopenia (14%), anemia (75%), neurological symptoms (43%), psychological symptoms (19%) and dyspnea (9%). The results are similar to other studies and toxicity was only moderate.

RESUMO

The combination of 5-fluorouracil (5-FU) and folinic acid (FA) has demonstrated activity in colorectal cancer (CC). Cisplatin is reported to have synergistic activity with 5-FU. We examined the combination FA + 5-FU + cisplatin in patients who had previously received chemotherapy with FA + 5-FU and relapsed. Two months after the last dose of FA + 5-FU and documentation of relapse, patients continued with the regimen consisting of cisplatin 20 mg/m2 in 15 min i.v. infusion followed by FA 500 mg/m2 in 1 h i.v. infusion, in the middle of which 5-FU 500 mg/m2 i.v. bolus was administered, with adequate post-hydration. This was repeated weekly for 4 weeks followed by a 2 week rest, for a maximum of six cycles. A total of 30 patients with CC that had relapsed to the combination of FA + 5-FU were treated; 23 had previous surgery and none had radiotherapy. Local recurrence was found in eight patients, metastases in the liver in 21, in lymph nodes in six, lung six and peritoneal metastases in seven. Seven patients responded partially. Toxicity requiring dose reduction or discontinuation of treatment included neutropenia 42% (grade 3:7%), mucositis 28% (grade 1:2), diarrhea 63% (Grade 3:10%), nausea-vomiting 55% (Grade 3:10%), increased creatinine value in three patients and peripheral neuropathy in two patients. We conclude that evaluation of this regimen shows substantial toxicity, with satisfactory response as a second line chemotherapy in these heavily pretreated patients.

RESUMO

The purpose of this study was to determine whether preloading administration of ondansetron given 12.5 h before cisplatin therapy, every 6 h, is better in controlling acute cisplatin-induced emesis than a standard dose every 8 h. All patients had previously received three cycles of CDDP-based chemotherapy in a dose of 100 mg/m2. Ondansetron was given according to two schedules: in group A (40 patients) at a dose of 8 mg in 100 ml normal saline over 10 min by intravenous infusion before the infusion of CDDP continued with 1 tablet of 8 mg after 8 and 16 h; in group B (40 patients) it was administered in six intravenous doses (every 6 h) starting 12.5 h before cisplatin administration. During the following 3 days, patients from both groups continued with tablets of 8 mg orally, every 8 h in group A and every 6 h in group B. The only difference in terms of the antiemetic response noticed between the two groups was in the number of patients that presented with nausea, which was increased in group A (32) in comparison to group B (25; p < 0.022). No difference was found in the number of vomiting episodes, retches or control of emesis, during the 3-day evaluation period after cisplatin infusion, and in secondary side effects. In conclusion the total dose of 24 mg ondansetron during the acute phase of emesis is as effective as preloading and increasing the total dose to 32 mg.

RESUMO

From June 1986 to February 1989, 103 patients with advanced non-small cell lung cancer, with no previous chemotherapy, were randomized to receive either a combination of cisplatin and vinblastine (group A) or the same combination with the addition of mitomycin (group B). In group A, 15/48 evaluable patients had objective responses, as did 8/45 in group B. The median survivals were 35 and 32 weeks, respectively. The median survival of patients with response or stable disease was 43 weeks. Response and survival did not differ significantly between treatment groups. The addition of mitomycin to the two-drug combination showed no major therapeutic benefit, while bone marrow toxicity was increased. Three patients in group B died of sepsis. Among the different patient characteristics, disease stage, performance status and response had influence on survival.

RESUMO

PURPOSE: To evaluate the efficacy and toxicity of the FAP combination chemotherapy as first-line treatment in advanced urothelial cancer. PATIENTS AND METHODS: Thirty-four patients with histologically confirmed advanced urothelial cancer, with measurable disease and without previous chemotherapy entered the study; all 34 are evaluable. The 28 males and 6 females had a median age of 65 (19-75) and a median ECOG performance status of 1 (0-2). Twenty-eight patients had bladder cancer, four had renal pelvic cancer and two ureteral cancer. Thirty patients had transitional cell carcinoma and four mixed, mostly of grade 3. Sites of disease included lymph nodes (18), bladder (9), liver (9), pelvic mass (9), lung (7), etc. The treatment plan was as follows: 5-fluorouracil 500 mg/m2 continuous infusion D1-D5 and D22-D26; interferon-alpha-2b 5 million i.u./m2 D1-D5 followed by 3x/week and then D22-D26; cisplatin 25 mg/m2 D1, D8, D15, D22. Cycles were repeated every 36 days. RESULTS: The median number of cycles administered was 3 (1-6). The relative dose intensities for 5-fluorouracil, interferon and cisplatin were 76%, 71% and 75%, respectively. Twenty-two of 34 patients (65%, 95% confidence interval [95% CI], 46% to 80%) had objective responses, including six complete clinical responses (CR) (18%, 95% CI, 7% to 35%) and 16 partial responses (PR) (47%, 95% CI, 30% to 65%). Three patients had stable disease and seven progressed. Two patients discontinued treatment after the first cycle because of toxicity. The median survival is 15.30 months (1.40-37.60), the median time to progression 11.60 months (4.13-37.60), and the median survival of complete responders 20.75+ months (8+ to 38+). The only significant hematologic toxicity was the grade 3-4 neutropenia in 44%. Non-hematologic toxic effects were unremarkable. CONCLUSION: The FAP combination as first-line chemotherapy is highly active in the treatment of advanced urothelial cancer, and has limited toxicity. Further phase III studies are in progress to compare FAP and M-VAC.
