Abstract
OBJECTIVES To evaluate the efficacy and safety of docetaxel in combination with carboplatin as salvage treatment in women with metastatic breast cancer (MBC). PATIENTS AND METHODS Chemotherapy-pretreated women with MBC were treated with docetaxel 75 mg/m(2) as 1-hour i.v. infusion followed by carboplatin AUC 6 mg/ml.min, using the Calvert's formula, as 30-min i.v. infusion. Cycles were repeated on an outpatient basis every 3 weeks. RESULTS Thirty-six patients received a total of 210 chemotherapy cycles (median 6 cycles/patient). All but one patient had previously received anthracyclines for the treatment of metastatic disease and half of the patients had failed to respond to front-line treatment. Twenty-eight (78%) patients had visceral disease. On an intention-to-treat analysis there were three (8%) complete and 19 (53%) partial responses for an overall response rate of 61% (95% CI: 45.2-77.0%). The response rate was 44% (2 CRs, 6 PRs) among 18 patients who had progressive or stable disease as best response to front-line treatment. The median duration of response was 8 months, the median time to tumor progression 10 months, and the probability of 1-year survival 66%. Grade 3-4 neutropenia was the main hematologic toxicity occurring in 16 (45%) patients or 36 (17%) cycles. Seven (19%) patients developed 8 (4%) febrile neutropenic episodes. Grade 3 thrombocytopenia occurred in 4 (11%) patients or 6 (3%) cycles. Non-hematologic toxicity was generally mild. G-CSF was used in 19 (53%) patients or 134 (64%) cycles. There was one sudden death possibly related to the treatment. CONCLUSION The docetaxel-carboplatin combination is an active outpatient salvage regimen for the treatment of women with MBC relapsing or not responding to anthracycline-based front-line therapy.

Abstract
Given the established individual activity of docetaxel and ifosfamide in anthracycline pretreated advanced breast cancer, the present phase I-II study aimed to define the maximum tolerated dose (MTD), the dose-limiting toxicities (DLTs), and activity of the docetaxel-ifosfamide combination in this setting. Cohorts of three to six patients with histologically confirmed metastatic breast cancer after prior anthracycline-based chemotherapy were treated at successive dose levels (DLs) with escalated doses of docetaxel 70-100 mg x m(-2) over 1 h on day 1 followed by ifosfamide 5-6 g x m(-2) divided over days 1 and 2 (2.5-3.0 g x m(-2) day(-1) over 1 h), and recycled every 21 days. G-CSF was added once dose-limiting neutropenia was encountered at a certain DL and planned to be incorporated prophylactically in subsequent higher DLs. In total, 56 patients with a median age of 54.5 (range, 32-72) years and performance status (WHO) of 1 (range, 0-2) were treated at five DLs as follows: 21 in phase I DLs (DL1: 3, DL2: 6, DL3: 3, DL4: 6, and DL5: 3) and the remaining 35 were treated at DL4 (total of 41 patients at DL4), which was defined as the level for phase II testing. All patients were assessable for toxicity and 53 for response. Dose-limiting toxicity (with the addition of G-CSF after DL2) was reached at DL5 with two out of three initial patients developing febrile neutropenia (FN). Clinical response rates, on an intention-to-treat basis, in phase II were: 53.6% (95% CI, 38.3-68.9%); three complete remissions, 19 partial remissions, seven stable disease, and 12 progressive disease. The median response duration was 7 months (3-24 months), median time to progression 6.5 month (0.1-26 month), and median overall survival 13 months (0.1-33 months). Grade 3/4 toxicities included time to progression neutropenia in 78% of patients-with 63% developing grade 4 neutropenia (<or=7 days) and in 12% of these FN, while no grade 3/4 thrombocytopenia was observed. Other toxicities included peripheral neuropathy grade 2 only in 12%, grade 1/2 reversible CNS toxicity in 17%, no renal toxicity, grade 2 myalgias in 10%, grade 3 diarrhoea in 10%, skin/nail toxicity in 17%, and grade 2 fluid retention in 2% of patients. One patient in the study treated at phase II died as a result of acute liver failure after the first cycle. In conclusion, the present phase I-II study determined the feasibility of the docetaxel-ifosfamide combination, defined the MTD and demonstrated the encouraging activity of the regimen in phase II, thus warranting further randomised phase III comparisons to single-agent docetaxel or combinations of the latter with other active agents.

Abstract
PURPOSE To evaluate the prognostic significance of molecular detection of cytokeratin 19 (CK-19) mRNA-positive cells by nested reverse transcriptase polymerase chain reaction (RT-PCR) in the peripheral blood of women with stages I and II breast cancer before adjuvant chemotherapy. PATIENTS AND METHODS The sensitivity and specificity of CK-19 mRNA detection by nested RT-PCR were investigated using MCF-7 and ARH-77 cells and blood from healthy women and patients with hematologic malignancies, metastatic colorectal cancer, and early and metastatic breast cancer. Peripheral blood from 148 patients with operable breast cancer, obtained before initiation of any adjuvant therapy, was tested for the presence of CK-19 mRNA-positive cells. RESULTS The nested RT-PCR assay for CK-19 mRNA detected one MCF-7 tumor cell in 10(6) normal peripheral blood mononuclear cells in four of five experiments; no signal was detected with the CK-19-negative ARH-77 cells. CK-19 mRNA was detected in the peripheral blood of 3.7% of healthy blood donors, 14.3% of patients with hematologic malignancies, and 3.2% of patients with metastatic colorectal cancer. Detection rates for CK-19 mRNA-positive cells in the bone marrow/blood of patients with early or metastatic breast cancer were 63%/30% and 74%/52%, respectively. For stages I and II breast cancer, detection of CK-19-positive cells in the peripheral blood before adjuvant therapy was associated with reduced disease-free interval (P =.0007) and overall survival (P =.01). In multivariate analysis, detection of peripheral-blood CK-19-positive cells was an independent prognostic factor for disease relapse and death. CONCLUSION Molecular detection of CK-19 mRNA-positive cells by RT-PCR in the peripheral blood of patients with stages I and II breast cancer before initiation of adjuvant therapy has independent prognostic value as a marker of poor clinical outcome.

Abstract
AIM To define the maximum tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of the carboplatin-vinorelbine combination in pretreated patients with advanced breast cancer. PATIENTS AND METHODS Patients with histologically confirmed metastatic breast cancer relapsing or progressing after prior taxane and anthracycline containing chemotherapy were enrolled. Cohorts of 3-6 patients were treated at successive dose levels (DLs) with escalated doses of carboplatin [range, area under the curve (AUC) 4-6] on day 1 and vinorelbine (range, 20-35 mg/m(2)) on days 1 + 8 recycled every 28 days. RESULTS Twenty-seven patients with a median age of 58 years and performance status (WHO) of 0-2 were treated at 6 DLs. All patients were assessable for toxicity and 20 for response. DLT was reached at carboplatin 6 AUC and vinorelbine 35 mg/m(2), and therefore, this was considered as the MTD. Prophylactic G-CSF administration could not allow further dose escalation. The recommended dose for further phase II testing was defined at carboplatin 6 AUC on day 1 and vinorelbine 30 mg/m(2) on days 1 and 8. Among 98 administered treatment cycles 41 (42%) and 7 (7%) were complicated with grades 3 and 4 neutropenia and thrombocytopenia, respectively. Nonhematologic toxicities included grade 2 peripheral neuropathy in 3 cycles and grades 2 and 3 fatigue in 32 (32%). CONCLUSION The present study determined the feasibility of the combination of carboplatin at AUC 6 (day 1) and vinorelbine at 30 mg/m(2) (days 1 and 8 ) without G-CSF support in patients with taxane and anthracycline pretreated advanced breast cancer. Phase II studies at these doses should follow in order to determine the activity of the regimen.

Abstract
BACKGROUND Treatment options for patients with recurrent nonsmall cell lung carcinoma (NSCLC) remain limited as a result of poor activity of older agents after platinum-based therapy. In the current Phase II study, the authors evaluated the combination of gemcitabine and docetaxel in patients with recurrent NSCLC. METHODS Patients with advanced NSCLC (Stage IIIB-IV), a World Health Organization performance status (PS) < or = 2, prior paclitaxel plus platinum-based chemotherapy, and unimpaired hematopoietic and organ function were eligible. Chemotherapy was administered as follows: gemcitabine 1000 mg/m(2) was administered on Days 1 and 8 followed by docetaxel 100 mg/m(2) on Day 8, and this regimen was recycled every 21 days. Prophylactic granulocyte-colony stimulating factor was administered on Days 10-14 or until the patient achieved a white blood cell count > or = 5000/microL. RESULTS Of 43 patients who were entered on the study, 41 patients were evaluable for response, and all were evaluable for toxicity. The median patient age was 63 years (range, 47-70 years), the median PS was 1 (range, 0-2), there were 38 male patients, and there were 5 female patients. Four patients had Stage IIIA disease, 17 patients had Stage IIIB disease, and 22 patients had Stage IV disease. Histologies included 19 patients with adenocarcinoma, 18 patients with squamous cell carcinoma, and 3 patients with large cell carcinoma. Metastatic sites included lymph nodes in 28 patients, bone in 6 patients, liver in 5 patients, brain in 5 patients, lung nodules in 8 patients, adrenals in 7 patients, and other sites in 3 patients. All patients had received prior paclitaxel plus platinum-based treatment; 28 patients had received prior paclitaxel, ifosfamide, and cisplatin. Objective responses were partial response (PR) in 14 of 43 patients [33%; 95% confidence interval [95%CI], 18.5-46.6%], stable disease (SD) in 16 of 43 patients (37%; 95% CI, 22.8-51.6%), and progressive disease (PD) in 13 of 43 patients (30%; 95% CI, 16.3-43.7%). The median time to disease progression was 6 months (range, 1.0-20.0+ months), and the median survival was 8.5 months (range, 1.5-20.0+ months). The 1-year survival rate was 28%. Grade 3-4 neutropenia was experienced by 53% of patients (30% Grade 4), with 14% of patients experiencing febrile neutropenia. Grade 3 thrombocytopenia was experienced by 7% of patients (no Grade 4), whereas other Grade 3 nonhematologic toxicities were never encountered. CONCLUSIONS The combination of gemcitabine and docetaxel is active and is well tolerated in patients with advanced NSCLC who have failed prior taxane plus platinum chemotherapy. This regimen represents a tolerable and effective combination to apply in the palliative treatment of patients with recurrent NSCLC.

Abstract
OBJECTIVES To develop a highly sensitive quantitative RT-PCR hybridization assay for the determination of CK-19 mRNA in peripheral blood of patients with breast cancer. PATIENTS AND METHODS Quantification of CK-19 mRNA was based on the coamplification of CK-19 mRNA with a recombinant CK-19 RNA internal standard (CK-19 RNA-IS) through RT-PCR. The biotinylated amplification products were immobilized on steptavidin coated wells, hybridized with digoxigenin labeled probes and determined through an antidigoxigenin antibody conjugated to alkaline phosphatase by luminometric detection. The developed luminometric hybridization assay was validated with samples containing total RNA of known amounts from CK-19 expressing cells (MCF-7) in the presence of 1 microg total RNA isolated from peripheral blood mononuclear cells (PBMC) of healthy controls and a constant amount of CK-19 RNA-IS. The method was applied for the quantitative determination of CK-19 mRNA in the peripheral blood of 26 healthy volunteers, 14 patients with stage IV breast cancer and 37 patients with stage I/II breast cancer before chemotherapy. RESULTS Luminescence ratios for CK-19 mRNA and CK-19 RNA-IS were linearly related to the number of MCF-7 cells within the range of 1 to 2000 cells. The overall reproducibility of the assay (between-run) varied between 8.9% and 13.4%. The method can clearly detect CK-19 mRNA from 1 MCF-7 cell in the presence of 10(6) normal PBMC and is highly specific as none of the 26 healthy controls tested had detectable CK-19 mRNA levels, while 10 out of 14 (71.4%) and 9 out of 37 (24.3%) patients with stage IV and stage I/II breast cancer, respectively, were tested positive. CONCLUSION The developed quantitative RT-PCR hybridization assay for CK-19 is reproducible, highly sensitive and specific, and can be used for a large-scale prospective evaluation of clinical samples.

Abstract
PURPOSE To evaluate the efficacy and safety of oxaliplatin (L-OHP) in combination with leucovorin (LV)-modulated bolus plus infusional 5-fluorouracil (5-FU; de Gramont schedule) every 2 weeks in chemotherapy-naive patients with advanced colorectal cancer (CRC). PATIENTS AND METHODS Thirty-two patients (median age: 69 years) with histologically confirmed and two-dimensionally measurable metastatic CRC were enrolled. The patients' performance status (WHO) was 0 in 14 (44%), 1 in 15 (47%), and 2 in 3 (9%) patients. Twenty (62.5%) patients had at least two metastatic sites. LV was administered at a dose of 200 mg/m2/day as a 2-hour intravenous infusion, followed by 5-FU as an intravenous bolus at the dose of 400 mg/m2 and then, as a 22-hour continuous infusion at the dose of 600 mg/m2/day for 2 consecutive days. L-OHP was administered on day 1 at the dose of 85 mg/m2 as a 2-hour infusion in parallel with LV but using different infusion lines. Treatment was administered every 2 weeks. RESULTS In an intention-to-treat analysis, 2 (6.2%) complete and 9 (28%) partial responses (28%; odds ratio 34.2%; 95% confidence interval 17.92-50.83%) were achieved while 8 (25%) patients had stable disease and 13 (41%) progressive disease. The median duration of response was 5 months, but the median time to progression has not yet been reached. After a median follow-up period of 11 months, the median survival has not yet been attained, but the projected probability for 1-year survival was 72%. Grade 3/4 neutropenia occurred in 16 (50%) patients while 1 (3%) of them developed febrile neutropenia. There was no treatment-related death. Peripheral neuropathy grade 2 and > or =3 occurred in 5 (16%) and 7 (21%) patients, respectively. CONCLUSIONS The bimonthly administration of L-OHP in association with LV-modulated bolus plus infusional 5-FU ('de Gramont' regimen) is a well-tolerated and effective front-line treatment for metastatic CRC.

Abstract
PURPOSE To evaluate the activity and tolerance of docetaxel in combination with mitoxantrone and granulocyte colony-stimulating factor (G-CSF) as front-line treatment in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS Fifty-four previously untreated patients with MBC who had bidimensionally measurable disease were enrolled onto the study. Forty-eight (89%) patients had visceral metastases and nineteen (36%) had relapsed within twelve months following adjuvant chemotherapy. Docetaxel (100 mg/m2) was given on day 1 after appropriate premedication and mitoxantrone (20 mg/m2) on day 8. G-CSF (150 mcg/m2/d s.c.) was administered from day 2 to day 6 and from day 9 to day 15. The regimen was repeated every three weeks, on an outpatient basis. RESULTS In an intention-to-treat analysis, 9 (17%) CRs, 24 (44%) PRs, (overall response rate 61%; 95% confidence interval (CI): 48.1%-74.1%), 12 (22%) SD and 9 (17%) PD were observed. The median duration of response and the median time to tumor progression was 12.5 and 14 months, respectively. The overall median survival was 16.5 months, whilst the probability for one- and three-year survival was 61% and 35%, respectively. Grade 3-4 neutropenia occurred in 37 (69%) patients, and febrile neutropenia in 16 (30%); there was one death due to sepsis. Grade 3-4 thrombocytopenia occurred in four (8%) patients. Grade 2-3 neurosensory toxicity was observed in 8 (15%) patients and grade 2-3 asthenia in 24 (45%). CONCLUSIONS Docetaxel in combination with mitoxantrone and G-CSF support is an intensified and active front-line regimen for patients with MBC; despite its hematological toxicity, this regimen merits further comparison with other standard anthracycline- and/or taxane-based combinations.

Abstract
Treatment options in patients with recurrent non-small-cell lung cancer (NSCLC) remain limited as a result of the poor activity of older agents after platinum-based therapy. The present phase II study aimed to evaluate the combination of gemcitabine and vinorelbine in patients with relapsed NSCLC after pretreatment with taxane+platinum-based regimens, since gemcitabine has demonstrated activity in that setting and the combination has been well tolerated in previous phase I/II studies. Patients with advanced NSCLC (stages III/IV), World Health Organization (WHO), Performance Status (PS) < or = 2, prior platinum+taxane-based chemotherapy and unimpaired haematopoietic and organ function were eligible. Chemotherapy was administered as follows: vinorelbine 25 mg/m(2) followed by gemcitabine 1000 mg/m(2), both administered on days 1 and 8, recycled every 3 weeks. 40 patients were entered and 39 were evaluable for response and all 40 for toxicity: median age was 61 years (range 50-72 years), median PS=1 (range 0-2), gender ratio=37 males/3 females, stages at initial diagnoses were IIIA=2, IIIB=14, IV=24. Metastatic sites included: lymph nodes: 23, bone: 4, liver: 5, brain: 4, lung nodules: 9, adrenals: 8, pleural effusion: 4. 22 patients had prior paclitaxel/ifosfamide/cisplatin treatment. Objective responses were; partial response (PR): 9/40 (22.5%), stable disease (SD): 13/40 (32.5%) and progressive disease (PD) 18/40 (45%). The median time-to-progression (TTP) was 4.5 months (range 1-17 months) and median survival 7 months (range 2-17+ months). 1-year survival was 17%. Grade 3 neutropenia was seen in 33% of patients. There was no grade 4 neutropenia and no episodes of febrile neutropenia. No grade 3/4 thrombocytopenia or grade 3/4 other non-haematological toxicities were observed. The combination of gemcitabine/vinorelbine is active and well tolerated in patients with advanced NSCLC failing prior taxane/platinum therapy. This regimen represents a tolerable and effective combination to apply in the palliative treatment of relapsed NSCLC.

Abstract
PURPOSE In a previous phase I trial we evaluated the toxicity and determined the maximum tolerated doses of the docetaxel (D)-epirubicin (Epi) combination. We conducted a multicenter phase II study to evaluate the efficacy and tolerability of this regimen as front-line treatment in women with advanced breast cancer (ABC). PATIENTS AND METHODS Fifty-four women with ABC stage IIIB (4 patients) or IV (50 patients) received front-line treatment with Epi 70 mg/m2 on day 1 and D 90 mg/m2 on day 2. The median age was 55 years, performance status (WHO) was 0-1 in 49 patients and visceral disease was present in 45 (83%). RESULTS All patients were evaluable for toxicity and 50 for response. In an intent-to-treat analysis complete remission was observed in 5(9%) patients, partial remission in 31 (57%) (overall response rate 66%, 95% confidence interval: 54% 79%), stable disease in 9 (17%) and disease progression in 9 (17%). After a median follow-up of 11.5 months, the median duration of responses was 8 months, the median time to disease progression 11.5 months and the median survival has not yet been reached. The probability of one-year survival was 65%. Three hundred six cycles of treatment were administered (median 6 cycles per patient). Grade 3 and 4 neutropenia was observed in 8 (15%) and 31 (57%) patients, respectively, and febrile neutropenia in 19 (35%). Prophylactic rh-G-CSF was used in 45 (83%) patients or 226 (74%) cycles. Other hematologic or non-hematologic toxicities were usually mild. In five (9%) patients the left ventricular ejection fraction (LVEF) was decreased by more than 10% with the treatment. Two patients died during the treatment of respiratory failure without associated neutropenia. CONCLUSIONS The combination of docetaxel epirubicin is an effective and well tolerated front-line treatment in patients with ABC.

Abstract
PURPOSE To determine the maximum tolerable dose (MTD) and the dose-limiting toxicity (DLT) of docetaxel (D) in combination with epirubicin (Epi) in patients with advanced breast cancer. PATIENTS AND METHODS Forty-seven chemotherapy-naïve metastatic breast cancer patients aged < 75 years with PS (WHO) 0-2 and adequate bone marrow, renal, liver and cardiac function, were enrolled in the study. Epi was given as a five-min bolus i.v. infusion on day 1 (d1) in escalated doses with increments of 10 mg/m2; D was given in a one-hour infusion after appropriate premedication on either day 1 or on day 2 in escalated doses with increments of 10 mg/m2. The patients' median age was 60 years, 42 (89%) had a PS (WHO) 0-1, 16 (34%) were premenopausal and 25 (53%) had visceral disease. RESULTS When the two drugs were given on the same day, the MTD1 was reached at the doses of Epi 60 mg/m2 and D 80 mg/m2; administration of G-CSF could not result in a dose intensification. When the drugs were given on two consecutive days, the MTD2 was reached at the doses of Epi 80 mg/m2 (d1) and D 90 mg/m2 (d2). The dose-limiting events were febrile neutropenia and grade 4 neutropenia, which developed in 30 (64%) patients during the study; among 227 delivered cycles grade 3-4 neutropenia occurred in 64 (28%) cycles but only 22 (10%) of them were complicated by fever. There were no septic deaths. Grade 1-2 neurosensory toxicity occurred in nine (19%) patients, mild edema in eight (17%) and allergic reactions in five (11%). Four (9%) patients presented a greater than 10% decrease of LVEF and treatment discontinuation was required in two of them; none of the patients developed congestive heart failure. Nevertheless, one patient suddenly died 10 days after treatment initiation of myocardial ischemia, and this death is considered treatment-related. Five (14.7%) complete and thirteen (38.2%) partial responses (ORR: 53.9%; 95% confidence interval: 36.1%-69.7%) were observed in 34 evaluable patients. Ten (29.4%) and six (17.6%) patients had stable and progressive disease, respectively. The median duration of response and time to tumor progression were five and seven months, respectively. The median survival has not yet been reached. CONCLUSIONS The combination of epirubicin and docetaxel is a feasible and well tolerated regimen, but the MTD depends on the administration schedule of the drugs.

Abstract
PURPOSE The activity of the docetaxel-gemcitabine combination in women with disease progression after initial chemotherapy for metastatic breast cancer (MBC) was investigated in a multicenter phase II study. PATIENTS AND METHODS Fifty-two patients with metastatic breast cancer who had disease relapse or progression after completion of an anthracycline-based front-line regimen were treated with gemcitabine 900 mg/m2 on day 1 and day 8 and docetaxel 100 mg/m2 on day 8. G-CSF 150 mucg/m2/d s.c. was given from day 9 to day 16 and the treatment was repeated every three weeks. The patients' median age was 57 years and the performance status (WHO) was 0 for 26, 1 for 20 and 2 for 6 patients. The treatment was second-line for 27 (52%) and > or = third-line for 25 (48%) patients. All patients were evaluable for response and toxicity. RESULTS Complete response occurred in seven (14%) patients and partial response in 21 (40%) for an overall response rate of 54% (95% confidence interval (95% CI): 40%-67%). Fifteen (29%) patients had stable disease and nine (17%) progressive disease. Of 25 patients previously treated with taxanes. 11 (44%) responded (1 CR, 10 PR). Interestingly, in four patients with disease progression while receiving docetaxel or paclitaxel monotherapy, the docetaxel + gemcitabine combination achieved partial responses. Responses were observed at all metastatic sites (local disease 62%, lymph nodes 58%, skin 44%, lung 47% and liver 36%) with a median duration of response of 3.6 months (range 1-16) and a median time to disease progression of eight months (range 2-18.5). Grade 3 neutropenia developed in 10 (19%) and grade 4 in five (10%) patients. Neutropenia was associated with infection in four patients without toxic deaths. Grade 3 thrombocytopenia developed in nine (17%) patients and grade 4 in two (4%). Non-hematologic toxicity was usually mild. CONCLUSION The docetaxel-gemcitabine combination is an active and well tolerated salvage treatment in patients with MBC. Previous treatment with taxanes does not preclude a good clinical response to this regimen.

Abstract
The independent effects of several patient, tumor and treatment-related prognostic factors on relapse-free survival (RFS) and overall survival (OS) were assessed by Cox multivariate regression analysis in 988 Greek patients with stage II breast cancer. At a median follow-up time of 83 (range 3.3-131+) months and after the evaluation of all patients together, the number of positive axillary nodes (p < 0.0001), tumor size (p = 0.0024) and tumor grade (p = 0.0008) were identified as significant prognostic factors for RFS. Also, the number of positive nodes (p < 0.0001), tumor size (p = 0.0002) and ER status (p = 0.0001) were found to be significant for OS. These short-term prognostic variables are similar to those reported for this group of patients in other European countries and in the USA.

Abstract
Combined chemotherapy with radiotherapy has been claimed to be superior to radiotherapy alone in stage III non-small cell lung cancer (NSCLC). The present study was designed to give chemo-radiotherapy with 300 cGy only on the day the cytotoxic drugs are administered. The aim was to exploit the cell cycle synergism between the two treatments. Forty-five patients of stage IIIA+B with inoperable NSCLC were randomized in two groups. Group A to be treated with chemotherapy only and group B to be treated with chemotherapy plus radiotherapy. Drugs for group A were: cisplatinum 90 mg/m(2), vindesine 3 mg/m(2) and epirubicin 40 mg/m(2) once every 3 weeks for 8 courses. Group B: cisplatinum 60 mg/m(2), vindesine 3 mg/m(2) and epirubicin 30 mg/m(2) plus 300 cGy radiation, every two weeks for 8 cycles. Then, estimation of response was done. Toxicity was tolerable. In group A the response rate was 52%, in group B 90% (partial and complete). The difference was statistically significant. Additional radiotherapy up to 5,400 cGy was given in patients of group B while patients of group A had palliative radiation on recurrence. Survival rate was significantly longer for patients of group B.
