Weekly paclitaxel plus capecitabine in advanced breast cancer patients: dose-finding trial of GOIRC and GOL.

BACKGROUND: Paclitaxel and capecitabine have demonstrated a synergic effect and significant antitumor activity in patients with advanced breast cancer. A weekly schedule of paclitaxel obtained a response rate of 50-68% in advanced breast cancer and less serious side-effects. PATIENTS AND METHODS: Thirty-two patients with advanced breast cancer pretreated with chemotherapy were enrolled in a dose-finding trial to determine the maximum tolerated dose (MTD) and the dose-limiting toxicity (DLT) of paclitaxel given on days 1, 8 and 15 of each cycle combined with capecitabine given twice daily from day 1 through day 14, every 21 days. Three patients were recruited at one of six dose levels (paclitaxel 70-100 mg/m2, capecitabine 1650-2500 mg/m2). RESULTS: Thirty-two patients were accrued and 31 were evaluated for toxicity. One DLT has been experienced at level VI as diarrhea grade 3. We determined dose level V as the MTD, but we recommend dose level IV for phase II studies (capecitabine 1250 mg/m2 orally twice daily plus paclitaxel 80 mg/m2 intravenously weekly), owing to cumulative toxicity at level V. The objective response rate was 43%. CONCLUSIONS: Weekly paclitaxel plus capecitabine is a safety and active chemotherapy in previously treated metastatic breast cancer.

Modulation of 5-fluorouracil as adjuvant systemic chemotherapy in colorectal cancer: the IGCS-COL multicentre, randomised, phase III study.

The aims of this multicentre, randomised phase III trial were to evaluate: (1) the role of levamisol (LEV); and (2) the role of folinic acid (FA), added to 5-fluorouracil (5FU) in the adjuvant treatment of colorectal cancer. Patients with histologically proven, radically resected stage II or III colon or rectal cancer were eligible. The study had a 2x2 factorial design with four treatment arms: (a) 5FU alone, (b) 5FU+LEV, (c) 5FU+FA, (d) 5FU+LEV+FA, and two planned comparisons, testing the role of LEV and of FA, respectively. From March 1991, to September 1998, 1327 patients were randomised. None of the two comparisons resulted in a significant disease-free (DFS) or overall (OAS) survival advantage. The hazard ratio (HR) of relapse was 0.89 (95% confidence intervals (CI): 0.73-1.09) for patients receiving FA and 0.99 (95% CI 0.80-1.21) for those receiving LEV; corresponding HRs of death were 1.02 (95% CI: 0.80-1.30) and 0.94 (95% CI 0.73-1.20). Nonhaematological toxicity (all grade vomiting, diarrhoea, mucositis, congiuntivitis, skin, fever and fatigue) was significantly worse with FA, while all other toxicities were similar. In the present trial, there was no evidence that the addition of FA or LEV significantly prolongs DFS and OAS of radically resected colorectal cancer patients.

Phase II study of sequential hormonal therapy with anastrozole/exemestane in advanced and metastatic breast cancer.

Hormonal therapy is the preferred systemic treatment for recurrent or metastatic, post-menopausal hormone-receptor-positive breast cancer. Previous studies have shown that there is no cross-resistance between exemestane and reversible aromatase inhibitors. Exposure to hormonal therapy does not hamper later response to chemotherapy. Patients with locally advanced or metastatic, hormonal receptor positive or unknown, breast cancer were treated with oral anastrozole, until disease progression, followed by oral exemestane until new evidence of disease progression. The primary end point of the study was clinical benefit, defined as the sum of complete responses (CR), partial responses (PR) and > 24 weeks stable disease (SD). In all, 100 patients were enrolled in the study. Anastrozole produced eight CR and 19 PR for an overall response rate of 27% (95% CI: 18.6-36.8%). An additional 46 patients had long-term (> 24 weeks) SD for an overall clinical benefit of 73% (95% CI: 63.2-81.4). Median time to progression (TTP) was 11 months (95% CI: 10-12). A total of 50 patients were evaluated for the second-line treatment: exemestane produced one CR and three PR; 25 patients had SD which lasted > or = 6 months in 18 patients. Median TTP was 5 months. Toxicity of treatment was low. Our study confirms that treatment with sequential hormonal agents can extend the period of time during which endocrine therapy can be used, thereby deferring the decision to use chemotherapy.

A randomised factorial trial of sequential doxorubicin and CMF vs CMF and chemotherapy alone vs chemotherapy followed by goserelin plus tamoxifen as adjuvant treatment of node-positive breast cancer.

The sequential doxorubicin --> CMF (CMF=cyclophosphamide, methotrexate, fluorouracil) regimen has never been compared to CMF in a randomised trial. The role of adding goserelin and tamoxifen after chemotherapy is unclear. In all, 466 premenopausal node-positive patients were randomised to: (a) CMF x 6 cycles (CMF); (b) doxorubicin x 4 cycles followed by CMF x 6 cycles (A --> CMF); (c) CMF x 6 cycles followed by goserelin plus tamoxifen x 2 years (CMF --> GT); and (d) doxorubicin x 4 cycles followed by CMF x 6 cycles followed by goserelin plus tamoxifen x 2 years (A --> CMF --> GT). The study used a 2 x 2 factorial experimental design to assess: (1) the effect of the chemotherapy regimens (CMF vs A --> CMF or arms a+c vs b+d) and (2) the effect of adding GT after chemotherapy (arms a+b vs c+d). At a median follow-up of 72 months, A --> CMF as compared to CMF significantly improved disease-free survival (DFS) with a multivariate hazard ratio (HR)=0.740 (95% confidence interval (CI): 0.556-0.986; P=0.040) and produced a nonsignificant improvement of overall survival (OS) (HR=0.764; 95% CI: 0.489-1.193). The addition of GT after chemotherapy significantly improved DFS (HR=0.74; 95% CI: 0.555-0.987; P=0.040), with a nonsignificant improvement of OS (HR=0.84; 95% CI: 0.54-1.32). A --> CMF is superior to CMF. Adding GT after chemotherapy is beneficial for premenopausal node-positive patients.

Weekly paclitaxel as first-line chemotherapy in elderly advanced breast cancer patients: a phase II study of the Gruppo Italiano di Oncologia Geriatrica (GIOGer).

BACKGROUND: First-line chemotherapy regimens suitable for elderly advanced breast cancer patients are still not defined. PATIENTS AND METHODS: Women with stage III or IV breast cancer aged > or =70 years were enrolled in a phase II study aimed to evaluate both activity and toxicity of weekly paclitaxel. Among 46 planned patients, at least 18 responses and not more than seven unacceptable toxic events are required for a favourable conclusion. Paclitaxel 80 mg/m(2) was administered weekly for 3 weeks every 28 days. RESULTS: Unacceptable toxicity occurred in seven out of 46 patients evaluated for toxicity [15.2%; exact 95% confidence interval (CI) 7.6% to 28.2%] and was represented by one case of febrile neutropenia, one case of severe allergic reaction and five cases of cardiac toxicity. Among 41 patients evaluated for response, a complete response occurred in two (4.9%) patients and a partial response in 20 (48.8%), with an overall response rate of 53.7% (exact 95% CI 38.7% to 67.9%). The median progression-free survival was 9.7 months (95% CI 8.5-18.7) and median survival was 35.8 months (95% CI 19-not defined). CONCLUSIONS: Weekly paclitaxel is highly active in elderly advanced breast cancer patients. Data on cardiovascular complications, however, indicate the need for a careful monitoring of cardiac function before and during chemotherapy.

FOLFIRI regimen in advanced colorectal cancer: the experience of the Gruppo Oncologico dell'Italia Meridionale (GOIM).

PURPOSE: To verify the experience of the GOIM in the treatment of advanced colorectal cancer patients with the FOLFIRI combination therapy. PATIENTS AND METHODS: Patients entered in three consecutive trials of the GOIM (protocols no. 9706, 9901, and 2301) were reported in this analysis. A total of 287 chemotherapy-naive patients were treated with FOLFIRI regimen: Irinotecan 180 mg/m(2) on day 1 with LV5FU2 regimen (LV at 100 mg/m(2) administered as a 2-hour infusion before FU at 400 mg/m(2) as an intravenous bolus injection, and FU at 600 mg/m(2) as a 22-hour infusion immediately after 5FU bolus injection on day 1 and 2); the treatment was repeated every 2 weeks. RESULTS: 287 patients entered in these three trials, and 264 (92%) were evaluable for response. The overall response rate was 34.5% (95% confidence interval [CI]: 29% to 40%). When only assessable patients were analyzed, overall response rate was 37% (95% CI: 31% to 43%). Median time to progression, median duration of response and survival were 7 months, 10.5 months and 14 months, respectively. All but three patients were evaluable for toxicity which was globally mild; grade 3-4 toxicity was uncommon, and gastrointestinal disturbances were the most common. CONCLUSIONS: FOLFIRI regimen is effective and well-tolerated as first-line treatment in patients with advanced colorectal cancer. Further studies needed to evaluate the improvement in results with the addition of new drugs to this combination therapy.

Randomised, open-label, phase II trial of paclitaxel, gemcitabine and cisplatin versus gemcitabine and cisplatin as first-line chemotherapy in advanced transitional cell carcinoma of the urothelium.

The purpose of the study was to evaluate the antitumor activity and the safety of paclitaxel combined with gemcitabine and cisplatin in patients affected by advanced transitional cell carcinoma of the urothelium (TCC). Eighty-five patients affected by advanced TCC and measurable disease were randomized to receive either paclitaxel at dosage of 70 mg/m2, gemcitabine 1000 mg/m2 and cisplatin 35 mg/m2 on days 1 and 8 every 3 weeks (GCP) or gemcitabine 1000 mg/m2 on days 1, 8, 15 and cisplatin 70 mg/m2 on day 2 every 4 weeks (GC). All enrolled patients were considered evaluable for response and toxicity (intention to treat). The observed response rate was 43% for GCP and 44% for GC combination, respectively. Median time to treatment failure was 32 weeks for GCP and 26 weeks for GC and overall survival 61 vs 49 weeks, respectively (p-value not significant). Grade 3-4 neutropenia was observed in 49% of patients treated with GCP vs 35% of those treated with GC (P=0.05) and grade 3-4 thrombocytopenia was observed in 36% of GCP treated patients as compared to 21% of those treated with GC (P=0.01). Seven patients over 70 years old or with poor PS were removed from the study: 6 patients from GCP group (2 toxic deaths, 2 grade 4 myelotoxicity and 2 grade 3 asthenia) and 1 from GC group was lost to follow-up after the first cycle. The combination of paclitaxel, gemcitabine and cisplatin is effective in the treatment of TCC. However, the addition of paclitaxel to the combination of gemcitabine plus cisplatin seems to increase toxicity, therefore it seems not suitable for poor PS patients and those over 70 years old. Larger and more powered studies are needed to exactly define the role of paclitaxel in this combination.

Prevalence and management of pain in Italian patients with advanced non-small-cell lung cancer.

Pain is a highly distressing symptom for patients with advanced cancer. WHO analgesic ladder is widely accepted as a guideline for its treatment. Our aim was to describe pain prevalence among patients diagnosed with advanced non-small-cell lung cancer (NSCLC), impact of pain on quality of life (QoL) and adequacy of pain management. Data of 1021 Italian patients enrolled in three randomised trials of chemotherapy for NSCLC were pooled. QoL was assessed by EORTC QLQ-C30 and LC-13. Analgesic consumption during the 3 weeks following QoL assessment was recorded. Adequacy of pain management was evaluated by the Pain Management Index (PMI). Some pain was reported by 74% of patients (42% mild, 24% moderate and 7% severe); 50% stated pain was affecting daily activities (30% a little, 16% quite a bit, 3% very much). Bone metastases strongly affected presence of pain. Mean global QoL linearly decreased from 64.9 to 36.4 from patients without pain to those with severe pain (P<0.001). According to PMI, 616 out of 752 patients reporting pain (82%) received inadequate analgesic treatment. Bone metastases were associated with improved adequacy and worst pain with reduced adequacy at multivariate analysis. In conclusion, pain is common in patients with advanced NSCLC, significantly affects QoL, and is frequently undertreated. We recommend that: (i). pain self-assessment should be part of oncological clinical practice; (ii). pain control should be a primary goal in clinical practice and in clinical trials; (iii). physicians should receive more training in pain management; (iv). analgesic treatment deserves greater attention in protocols of anticancer treatment.

Supportive care in patients with advanced non-small-cell lung cancer.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.

Phase III multicenter randomized trial of amifostine as cytoprotectant in first-line chemotherapy in ovarian cancer patients.

BACKGROUND: A phase III multicenter randomized trial has been designed in order to address whether amifostine (WR-2721, Ethyol), an organic thiophosphate cytoprotector, can protect ovarian cancer patients from toxicity induced by carboplatin-paclitaxel chemotherapy. PATIENTS AND METHODS: Patients were randomly assigned to receive carboplatin [area under the curve (AUC) 5 mg.min/ml] and paclitaxel (175 mg/m(2)) with (arm A) or without (arm B) amifostine (910 mg/m(2)) every 21 days for six cycles. RESULTS: One-hundred and eighty-seven patients were accrued: 93 patients in arm A and 94 patients in arm B. There was no difference in terms of erythrocytopenia between the two arms; grade 3-4 thrombocytopenia was higher in arm A (3.3% versus 0.6%; P = 0.0010). There was no significant reduction of grade 3-4 leukopenia in arm A (11.8% versus 13.8%). The incidence of grade 3-4 neutropenia was lower in arm A (31.3% versus 37.9%; P = 0.03), as was the incidence of severe mucositis (4.7% versus 15.4% in arm A versus arm B, respectively; P <0.0001). Finally, amifostine appears to be protective against neurotoxicity (grade 3-4 neurotoxicity 3.7% versus 7.2%; P = 0.02). With a median follow-up of 24 months (range 2-41), time to progression was similar between the two groups. CONCLUSIONS: We showed that amifostine can exert some protection from the cumulative toxicity associated with this regimen. The results need to be confirmed in other randomized trials with this combination.

An escalating dose finding study of liposomal doxorubicin and vinorelbine for the treatment of refractory or resistant epithelial ovarian cancer.

BACKGROUND: The aim of this study was to determine the maximum tolerated dose (MTD) of liposomal doxorubicin (LD)-vinorelbine (V) in patients with refractory or resistant ovarian cancer. PATIENTS AND METHODS: Thirty patients were eligible. Seven levels were studied [LD 25-V20 (three patients enrolled); LD 30-V20 (three); LD 35-V20 (three); LD 20-V25 (three); LD 25-V25 (three); LD 30-V25 (10); LD 35-V25 (five)]. LD was given on day 1, while V was given on days 1 and 8 every 21 days. Cohorts of three patients were enrolled at each level, and another three patients were planned, if one dose-limiting toxicity (DLT) was registered. RESULTS: DLT was observed in four patients: two febrile neutropenia, one grade 4 thrombocytopenia and one grade 3 palmar-plantar erythrodysesthesia (PPE) at level 7 (LD 35-V25). Thus, liposomal doxorubicin 30 mg/m(2) plus vinorelbine 25 mg/m(2) was the MTD. The most frequent toxicity was neutropenia. Fifteen patients (50%) experienced grade 3 neutropenia and 10 (33.3%) grade 4 neutropenia. Non-hematological toxicity was mild. Mucositis and PPE were the most frequent toxicities, but in most cases were grade 1. Out of 29 assessable patients, six (20.7%; 95% confidence interval 10%-39%) experienced an objective response, with one complete response. CONCLUSIONS: In patients with refractory or resistant ovarian cancer, the recommended doses for the combination studied are liposomal doxorubicin 30 mg/m(2) (day 1) plus vinorelbine 25 mg/m(2) (day 1 and 8). Neutropenia is the most frequent toxicity, while non-hematological toxicity is mild. Substantial activity was recorded and a phase II study is justified.

Carboplatin plus paclitaxel in extensive small cell lung cancer: a multicentre phase 2 study.

A multicentre phase 2 trial (single-stage design) was undertaken to test the efficacy and toxicity of carboplatin (AUC 6 according to Calvert) plus paclitaxel (175 mg/m(2)3-h infusion) every 4 weeks in the first line treatment of patients affected by extensive small cell lung cancer. The primary end-point of the trial was the objective response rate. 31 objective responses among 50 patients were considered necessary to proceed to a phase 3 trial. 48 patients were enrolled (median age 59 years). Treatment was very well tolerated. 3 patients (6.2%) had a complete response and 23 (47.9%) a partial response, for an overall response rate of 54.2% (95% CI: 39.2-68.6). Median time to progression was 5.7 months (95% CI: 5.2-6.2). Median survival was 9.6 months (95% CI: 7.2-14.6), with a median follow-up time of alive patients of 12 months. At 1 year, the probability of being progression-free or alive was 0.16 and 0.43, respectively. In conclusion, carboplatin plus paclitaxel as given in the present study is very well tolerated but not sufficiently active to warrant phase 3 comparison with standard chemotherapy regimens.

Docetaxel and cisplatin in locally advanced or metastatic squamous-cell carcinoma of the head and neck: a phase II study of the Southern Italy Cooperative Oncology Group (SICOG).

BACKGROUND: Docetaxel is one of the most promising new drugs against squamous-cell carcinoma of the head and neck (SCCHN), while cisplatin is one of the most active single agents. A phase I study has shown the feasibility of the combination of the two drugs, and activity in SCCHN has been seen. PATIENTS AND METHODS: Patients with locally advanced, inoperable, or metastatic SCCHN, never pretreated with radiotherapy or chemotherapy, received three courses of docetaxel 75 mg/m2 and cisplatin 100 mg/m2, every three weeks. Thereafter, responsive metastatic patients received additional chemotherapy, while patients with locally advanced disease underwent radiation therapy. RESULTS: Forty-six patients (forty-five with locally advanced, one with metastatic disease) were entered into the study. Ten patients did not complete three courses of chemotherapy because of early death; one patient discontinued treatment after one course. Twenty-one objective responses were observed (46%, 95% confidence interval (CI): 31%-60%), including five complete responses (11%) and sixteen partial responses (35%). Following induction chemotherapy plus radiation therapy, 9 of 21 evaluable patients were rendered disease free, while 8 additional patients had a partial response. After a median follow-up of 18 months, the median duration of response was 12 months, (range 3-25+), and the median overall survival was 11 months. Six early deaths were considered possibly treatment-related (sepsis following grade 4 neutropenia in two cases, hypovolemic shock following severe diarrhea in four cases). Neutropenia was the most severe toxicity (grade 3-4 in 28 patients, median duration 4 days); diarrhea and vomiting were the most troublesome non-haematologic toxicities (grade 4 in 4 and 3 patients, respectively). CONCLUSIONS: The combination of docetaxel and cisplatin is active in SCCHN, but toxicity is substantial. This schedule does not appear to offer any advantage compared with conventional regimens.

Phase I study of a weekly schedule of oxaliplatin, high-dose leucovorin, and infusional fluorouracil in pretreated patients with advanced colorectal cancer.

PURPOSE: To identify the maximum tolerated dose (MTD) and dose limiting toxicities (DLT) of oxaliplatin (L-OHP) given on a weekly schedule including fixed doses of leucovorin (LV) and infusional 5-fluorouracil (5-FU), to define the toxicity profile of this regimen and to find preliminary evidence of its activity in pretreated patients with metastatic colorectal cancer (MCRC). PATIENTS AND METHODS: Twenty-one patients with progressive disease, treated with fluoropyrimidines and with histologically measurable MCRC entered into this phase I study. Fixed doses of LV (500 mg/m2) followed by a 48-hour 5-FU 2600 mg/m2 infusion (5-FU48h) were administered with escalating doses of L-OHP, starting from 60 mg/m2 and with stepwise increments of 5 mg/m2. No intra-patient dose escalation was allowed. Treatment was given once a week for four consecutive weeks, followed by a one-week rest period. RESULTS: Three dose levels were tested. The MTD was L-OHP 70 mg/m2 since two of the three patients showed dose-limiting diarrhea and the third developed neutropenia during the first cycle of chemotherapy. Most patients complained of mild peripheral sensitive neurotoxicity, which was related to the cumulative dose of L-OHP. Treatment delays were necessary for a total of 42 cases, but only in II of 42 after the pre-arranged 10% dose reduction of 5-FU (2300 mg/m2). Sixteen patients were evaluable for response: seven (33%; 95% confidence interval (CI): 14.6%-57.0%) were considered to show a major response (one complete), six showed a stable disease, and in addition progressive disease was observed in three patients. CONCLUSIONS: Our results show that L-OHP, LV and 5-FU can be administered safely and repetitively using a weekly schedule. Diarrhea and neutropenia are the DLT of this regimen. Its activity and its manageable toxicity profile deserve further evaluation in chemotherapy-naïve MCRC patients. The doses recommended for phase II trials are: L-OHP 65 mg/m2, LV 500 mg/m2 and 5-FU48h 2300 mg/m2 infusion given on a weekly-times-four schedule followed by a one-week rest period.

Quality of life in elderly cancer patients.

Increasing age is a major risk factor for developing cancer and the number of older people is rapidly expanding. Therefore, cancer in the geriatric population is becoming an emerging problem. Older patients are extremely heterogeneous. Instruments collecting information related to comorbidity and disability, (which have both been demonstrated to affect the survival of elderly patients) may help treatment decision. The G.I.O.Ger (Gruppo Italiano di Oncologia Geriatrica) has validated a Comprehensive Geriatric Assessment (CGA) scale for geriatric cancer patients, and we recommend its use in clinical practice. Our findings suggest that cancer adversely affects physical performance and psychological status less than other comorbidities. Many aspects of physical limitations are not totally recognised by performance status, in particular those aspects of daily life that require instrumental activities and that may affect adherence to diagnostic or therapeutic protocols. Quality of life as a main objective in the management of elderly cancer patients is now recognized by many clinicians. In clinical practice. quality of life means maintenance of function and symptom control, and quality-of-life instruments rated by the patient rather than by clinicians should be preferred. Whether it is preferable to use cancer-specific or generic instruments is an ongoing debate.

Topotecan and gemcitabine in platinum/paclitaxel-resistant ovarian cancer.

24 patients were enrolled into a phase I-II study conducted to determine the maximum tolerated doses of topotecan-gemcitabine in sequential combination and the response rate in platinum/paclitaxel resistant ovarian cancer patients. A total of 83 courses are evaluable, with a median number of three cycles administered per patients (range 2-7). Topotecan was administered on days 1-5 by 30 min i.v. infusion immediately after gemcitabine given by 30 min i.v. on days 1 and 3; cycles were repeated every 28 days. The starting doses were topotecan 0.7 mg/m(2) and gemcitabine 200 mg/m(2). Following dose levels were 08/400; 0.9/600; 0.9/800 for topotecan and gemcitabine, respectively. The maximum tolerated dose (MTD) was reached at dose level 3, the dose-limiting toxicity being represented by febrile neutropenia and thrombocytopenia. After the MTD was reached, granulocyte-colony-stimulating factor was administered in 27% of cycles. Mild and manageable was non hematological toxicity. All patients are so far evaluable for response. Among them 2 complete responses (8.3%; 95% CI: 2.6-19), 1 partial response (4.2%; 95% CI: 3.8-12), 9 no change (37.5%; 95% CI: 18-56.8) and 12 progressions (50%; 95% CI: 30-70) have been registered. Based on these data, there is no evidence that combining topotecan and gemcitabine is better than using either of the two drugs used separately.

Amifostine plus cisplatin plus vinorelbine in the treatment of advanced non small cell lung cancer: a multicenter phase II study.

PURPOSE: to evaluate the activity and toxicity of the combination cisplatin plus vinorelbine plus amifostine in advanced non small cell lung cancer (NSCLC). PATIENTS AND METHODS: a two-stage Simon design was applied. To proceed after the first stage, responses from seven of 19 patients were needed. Overall, 17 responses from 40 treated patients were required to comply with the design parameter. Inclusion criteria were cyto-histologically proven stage IIIB-IV NSCLC; age of 70 years or less; Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less; normal cardiac, hepatic, renal and bone marrow functions; and no previous chemotherapy. Patients were staged by physical examination, biochemistry, chest radiograph, brain, thoracic and abdominal computed tomographic (CT) scans, and bone scan. All patients received cisplatin 100 mg/m(2) intravenously (iv) day 1, vinorelbine 25 mg/m(2) iv days 1-8-15-22, amifostine 740 mg/m(2) iv day 1 every 4 weeks up to six cycles. Eleven of 40 enrolled patients were stage IIIB and 29 stage IV, with a median age of 57 years (range, 38-70 years). RESULTS: all patients were evaluable for response and toxicity (intention to treat analysis). We observed 20 (50%) objective responses, with four (10%) complete responses. Median time to progression was 20 weeks, and median survival was 45 weeks. The toxicity was manageable. The reported main toxicities were neutropenia grade 4 in 10% of patients, grade 1 and grade 3 nephrotoxicity both in 5% of patients and grade 1 amifostine-related hypotension in 15% of patients. CONCLUSION: these data show that cisplatin plus vinorelbine plus amifostine is an active and feaseable regimen in stage IIIB-IV NSCLC. A phase III trial comparing cisplatin plus vinorelbine versus cisplatin plus vinorelbine plus amifostine in advanced NSCLC is warranted.

Cisplatin, raltitrexed, levofolinic acid and 5-fluorouracil in locally advanced or metastatic squamous cell carcinoma of the head and neck: a phase I-II trial of the Southern Italy Cooperative Oncology Group (SICOG).

BACKGROUND: The combination of cisplatin (CDDP) and 5-fluorouracil (5-FU) can be regarded as a reference regimen in squamous cell carcinoma of the head and neck (SCCHN). Raltitrexed (Tomudex) is a direct and specific thymidilate synthase (TS) inhibitor, which has shown clinical activity against SCCHN in a previous phase I study, when combined with 5-FU and levo-folinic acid (LFA). Preclinical data support the combination of CDDP and raltitrexed. The aim of the present study was to evaluate the combination of cisplatin, raltitrexed. LFA and 5-FU in a phase I-II study. PATIENTS AND METHODS: Patients with locally advanced or metastatic SCCHN were treated with a combination of cisplatin at the starting dose of 40 mg/m2. followed by raltitrexed at the starting dose of 2.5 mg/m2 on day 1; levo-folinic acid at fixed dose of 250 mg/m2, followed by 5-fluorouracil at the starting dose of 750 mg/m2 on day 2. Doses of the three cytotoxic agents were alternately escalated up to dose-limiting toxicity (DLT). Treatment was recycled every two weeks and given up to a maximum of eight courses; after chemotherapy, patients with locally advanced disease received a locoregional treatment. RESULTS: Forty-five patients were entered into the study. Six dose levels were tested. At CDDP 50 mg/m2, raltitrexed 3 mg/m2, 5-FU 900 mg/m2, four out of six patients showed DLT, which was in all cases grade 4 neutropenia. Therefore, this dose level was defined as maximum tolerated dose (MTD). CDDP 60 mg/m2, raltitrexed 2.5 mg/m2, LFA 250 mg/m2, 5-FU 900 mg/m2 was the dose level recommended for phase II. CDDP, Raltitrexed and 5-FU mean actually delivered dose intensities at the selected dose level were 26, 1.05, and 378 mg/m2/week, respectively. Neutropenia was the main side effect and was observed even at the lowest dose levels. Nonhematologic side effects were mild. Nine complete responses (20%) and twenty-one partial responses (47%) were observed, for an overall response rate of 67% (95% confidence interval (95% CI): 51%-80%), according to intention to treat analysis. Fifteen of fifteen patients (100%) treated at the dose level selected for phase II had an objective response (5 complete responses, 10 partial responses). CONCLUSIONS: The results of our dose escalation clearly demonstrate that it is possible to combine CDDP, raltitrexed, and modulated 5-FU at effective doses, without unexpected toxicities. The response data point to an impressive clinical activity, which will be better defined by an ongoing large phase II study.
