Phase II trial of paclitaxel and cisplatin in metastatic and recurrent carcinoma of the uterine cervix.

PURPOSE: Both paclitaxel and cisplatin have moderate activity in patients with metastatic or recurrent cancer of the cervix, and the combination of these two agents has shown activity and possible synergism in a variety of solid tumors. We administered this combination to patients with metastatic or recurrent cervical cancer to evaluate its activity. PATIENTS AND METHODS: Thirty-four consecutive patients were treated on an outpatient basis with paclitaxel 175 mg/m2 administered intravenously over a 3-hour period followed by cisplatin 75 mg/m2 administered intravenously with granulocyte colony-stimulating factor support. The chemotherapy was administered every 3 weeks for a maximum of six courses. RESULTS: Sixteen patients (47%; 95% confidence interval, 30% to 65%) achieved an objective response, including five complete responses and 11 partial responses. Responses occurred in 28% of patients with disease within the radiation field only and in 57% of patients with disease involving other sites. The median duration of response was 5.5 months, and the median times to progression and survival for all patients were 5 and 9 months, respectively. Grade 3 or 4 toxicities included anemia in 18% of patients and granulocytopenia in 15% of patients. Fifty-three percent of patients developed some degree of neurotoxicity; 21% of cases were grade 2 or worse. CONCLUSION: The combination of paclitaxel with cisplatin seems relatively well tolerated and moderately active in patients with metastatic or recurrent cervical cancer. The significant incidence of neurotoxicity is of concern, and alternative methods of administration of the two agents could be evaluated. Then, further study of this combination, alone or with the addition of other active agents, is warranted.

Favorable outcome of ovarian germ cell malignancies treated with cisplatin or carboplatin-based chemotherapy: a Hellenic Cooperative Oncology Group study.

PURPOSE: To evaluate the outcome and the prognosis of patients with ovarian germ cell malignancies who were treated with platinum-based chemotherapy immediately after initial surgery. METHODS: We conducted a retrospective review of patients with ovarian germ cell tumors who were referred for consideration of treatment to the Departments of Medical Oncology participating in the Hellenic Cooperative Oncology Group. RESULTS: Over a 14-year period 53 patients were included in our study. There were 13 patients with dysgerminoma and 40 patients with nondysgerminomatous tumors. Forty percent of patients underwent complete resection of their tumors. Platinum-based chemotherapy consisted primarily of cisplatin, vinblastine, and bleomycin (PVB) in 9 patients; bleomycin, etoposide, and cisplatin (BEP) in 15 patients; and bleomycin, etoposide, and carboplatin (BEC) in 25 patients. With a median follow-up of 39 months, 5 patients developed progressive disease and died of their tumor and 1 patient died of bleomycin-induced lung toxicity with no evidence of active tumor. The 5-year overall survival was 100% for patients with dysgerminoma and 85% for patients with nondysgerminomatous tumors. Eighty percent of patients with advanced nondysgerminomatous tumors and residual disease after surgery remain disease free. CONCLUSION: With this study we confirm that patients with ovarian germ cell malignancies have a favorable outcome when treated with platinum-based chemotherapy.

Neo-angiogenesis in locally advanced squamous cell head and neck cancer correlates with thymidine phosphorylase expression and p53 nuclear oncoprotein accumulation.

Thymidine phosphorylase (Th.P) is an angiogenic factor shown to induce endothelial cell migration and proliferation. On the other hand, loss of wild type p53 function leads to down-regulation of thrombospondin-1, an inhibitor of angiogenesis. In this immunohistochemical study we investigated the intratumoural angiogenesis and thymidine phosphorylase (Th.P) expression in paraffin-embedded bioptical material from 104 locally advanced squamous cell head and neck cancers. The nuclear accumulation of mutant p53 protein and the cytoplasmic expression of bcl-2 protein was also assessed. High vascular grade was observed in 56% and high Th.P tumour cell reactivity in 48% of cases. High microvessel score was associated with an increased percentage of cancer cells expressing thymidine phosphorylase (P = 0.001). Increased p53 nuclear accumulation also correlated with high vascular grade (P = 0.001). High histological grade and absence of bcl-2 overexpression were associated with lymph node involvement (P = 0.002 and P = 0.02 respectively). No correlation of clinically detected lymphadenopathy with angiogenesis and p53 was observed. We conclude that intense neo-angiogenesis in locally advanced squamous cell head neck cancer is a frequent event, which is associated with nuclear p53 accumulation and thymidine phosphorylase overexpression.

First-line chemotherapy with paclitaxel by three-hour infusion and carboplatin in advanced breast cancer (final report): a phase II study conducted by the Hellenic Cooperative Oncology Group.

PURPOSE: To evaluate the activity and toxicity of the combination of paclitaxel given by three-hour infusion, and carboplatin as first-line chemotherapy in patients with advanced breast cancer (ABC). BACKGROUND: Paclitaxel is an active agent in ABC. Furthermore, our group has shown that the combination of paclitaxel and carboplatin is effective in anthracycline-resistant ABC. PATIENTS AND METHODS: From January 1996 until March 1997, 66 women with ABC were treated with paclitaxel (175 mg/m2) by three-hour infusion followed by carboplatin at an AUC of 6 mg x min/ml every three weeks. The median age of the patients was 56 years (range 28-75). A total of 39 patients had received adjuvant chemotherapy and 22 of them were treated with an anthracycline or mitoxantrone-containing regimen. RESULTS: A total of 324 cycles (median: six) were administered, 273 (85%) of them at full dose. The median number of delivered cycles was six. The median delivered dose intensity (DI) of paclitaxel was 55.1 mg/m2/week (range 30.5-69.3) and the relative DI was 0.95 (range 0.5-1.2). Eight patients (12%, 95% confidence interval (CI): 5%-22%) achieved complete and 28 (42%, 95% CI: 30%-55%) partial responses. Grade 3-4 toxicities included anemia (5%), granulocytopenia (24%), thrombocytopenia, nausea/vomiting and allergic reaction (3% each), myalgias/arthralgias and neurotoxicity (1.5% each). Febrile neutropenia occurred in eight (12%) patients. Alopecia was universal. After a median follow-up of 17.3 (range 0.07-24.5) months, 48 (72%) patients have demonstrated tumor progression and 24 (36%) have died. Median time to progression was 8.6 (range 0.07-23+) months and median survival 20.4 (range 0.07-24.5+) months. CONCLUSIONS: The combination of paclitaxel and carboplatin has moderate activity in ABC and can be easily delivered on an outpatient basis with manageable toxicity. This regimen may be useful especially in patients to whom anthracyclines or cisplatin administration is precluded because of other concomitant diseases.

Paclitaxel and carboplatin as first-line chemotherapy for advanced breast cancer.

In a phase II study, 66 patients with advanced breast cancer (median age 56 years; range, 28 to 75 years) were treated with paclitaxel (Taxol), 175 mg/m2 infused over 3 hours, and carboplatin (Paraplatin), dosed to attain an area under the concentration-time curve (AUC) of 6 mg x min/mL; treatment was repeated every 3 weeks. A total of 38 (58%) patients had received prior adjuvant chemotherapy, 21 with a regimen containing an anthracycline or mitoxantrone (Novantrone). As of May 1997, 295 cycles of paclitaxel-carboplatin have been administered, 248 (84%) at full dose. The relative dose intensity of paclitaxel is 0.9 (range, 0.5 to 1.2). Of the 66 patients, 8 (12%) have achieved a complete response and 27 (41%) a partial response, for a total response rate of 53%. Grade 3 to 4 toxicities have included anemia (5%), leukopenia (25%), thrombocytopenia (5%), nausea/vomiting (7%), myalgias/arthralgias (4%), allergic reaction, neurotoxicity, and infection (2% each). Alopecia has been universal. Median time to progression is 8.9 months; median survival has not yet been reached. We conclude that the combination of paclitaxel and carboplatin has significant activity in advanced breast cancer and can easily be administered on an outpatient basis with manageable toxicity.

Tropisetron in the prevention of acute nausea and vomiting in patients treated with high dose epirubicin.

Tropisetron is a novel selective antagonist of the type-3 serotonin (5-HT3) receptor, with proven efficacy in the control of emesis related to cancer treatment. Epirubicin in doses of > 100 mg/m2 has a high emetogenic potential. This study was designed to determine whether a single intravenous administration of tropisetron could prevent acute nausea and vomiting in patients treated with high dose epirubicin. Forty chemotherapy naive breast cancer patients treated with epirubicin at a dose of 110 mg/m2 on an outpatient basis were enrolled in the study. Tropisetron 5 mg i.v. was used as antiemetic prophylaxis. "On demand" treatment with tropisetron 5 mg p.os was used for the rescue of patients who failed on the initial i.v. dose. Complete control of acute nausea and vomiting had 62.5% (95% C.I. 47.2-77.8), partial control 15% (95% C.I. 3.8-26.2) and 22.5% (95% C.I. 9.3-35.7) insufficient control or failure. Headache was the most common adverse event reported in 3 patients (7.5%) and constipation in 2 patients (5%). Interestingly, patients with a negative experience of nausea and vomiting during pregnancy and those treated for metastatic disease, had a better control of chemotherapy-induced nausea and vomiting. In conclusion, a single 5 mg i.v. dose of tropisetron is safe and effective in preventing acute emesis in patients treated with high dose epirubicin.

Long-term survival data and prognostic factors of a complete response to chemotherapy in patients with head and neck cancer treated with platinum-based induction chemotherapy: a Hellenic Co-operative oncology Group study.

A group of 154 patients with locally advanced head and neck cancer, treated with platinum-based induction chemotherapy, were followed up for 5 years and several pretreatment characteristics were analyzed for possible correlation to a complete response (CR) to chemotherapy, time to progression (TTP) and overall survival (OS). Clinical stage (p = 0.0024) and a history of smoking (p = 0.0125) were selected as important prognostic factors for CR by step wise logistic regression. We also identified response to chemotherapy (p = 0.0120), age (p = 0.0066), clinical stage (p = 0.0363), N stage (p = 0.0028), and tumor grade (p = 0.0101) as significant prognostic variables for TTP. Response to chemotherapy (p < 0.0001) and age (p = 0.0017) were found also significant for OS. These long-term prognostic factors which retain their prognostic significance after several years of follow-up could be helpful in the design of future trials in this patient population.

A phase II study of paclitaxel in platinum pretreated ovarian cancer. A Hellenic Cooperative Oncology Group study.

Paclitaxel was administered at a dose of 175 mg/m2 in a 3-hour infusion every 3 weeks in platinum pretreated patients with ovarian cancer. 51 patients with a median age of 57 years entered the study. 33 (65%) presented with stage III and 18 (35%) with stage IV disease. 39 patients (76%) were previously treated with only one and 12 (24%) with two regimens. The median interval from the last previous chemotherapy was 4 months (range, 1-65). Ninety-eight per cent of the planned dose of paclitaxel was actually delivered. Overall and complete response rate was 26% (13/51) and 16% (8/51), respectively. All complete responses were observed among patients previously treated with only one regimen. Median time to progression was 10.26 months (range, 4.9-25.2+) and median survival 15.6 months (range, 1.3-27.1+). Factors influencing survival were performance status and the number of previous regimens.

Effectiveness of paclitaxel and carboplatin combination in heavily pretreated patients with head and neck cancers.

A phase II study was conducted to evaluate the activity of paclitaxel and carboplatin in advanced head and neck cancer. Twenty-four patients with measurable locoregional squamous cell carcinoma and metastatic disease were entered. All had been heavily pretreated with radiotherapy, surgery and chemotherapy and were at second recurrence or disease progression when they entered the trial. Patients received Paclitaxel 200 mg/m2 with carboplatin 7 AUC once every 3 weeks with premedication with dexamethasone and diphenyldramine and ranitidine. Twenty-three patients were evaluable for response. Four patients (17%) achieved a complete response and 5 (22%) a partial response for an overall response rate of 39%. Duration of response was 3-9 months. Toxicity was tolerable. Four patients showed Grade III (WHO) and 6 Grade II neutropenia. Nineteen (79%) of patients who received more than two courses of chemotherapy presented neurotoxicity. The combination of paclitaxel and carboplatin was effective in heavily pretreated patients with squamous cell carcinoma of the head and neck.

Paclitaxel by 3-h infusion and carboplatin in anthracycline-resistant advanced breast cancer. A phase II study conducted by the Hellenic Cooperative Oncology Group.

37 patients with advanced breast cancer resistant to anthracyclines were treated with paclitaxel 200 mg/m2 by 3-h infusion and carboplatin at an area under the curve of 7 mg.min/ml every 4 weeks with G-CSF support. There were 5 (14%, 95% CI 3-25%) complete and 11 (30%, 95% CI 15-45%) partial responders. Median duration of response was 11.5 months (range 5.2-16.8+), median time to progression 8 months (range 0.26-16.8+) and median survival 12 months (range 0.5-19.6+). Grade 3-4 leucopenia (27%), thrombocytopenia (10%) and diarrhoea (5%) were noted. In conclusion, the combination of paclitaxel and carboplatin is active and well tolerated in patients with advanced breast cancer resistant to anthracyclines.

Paclitaxel and carboplatin in inoperable non-small-cell lung cancer: a phase II study.

BACKGROUND: Based on the high activity of single-agent paclitaxel and the superior one-year survival rates of patients with non-small-cell lung cancer (NSCLC) treated with carboplatin, a phase II trial was initiated using both agents in patients with inoperable stages III and IV disease to investigate the efficacy and toxicity of the combination. PATIENTS AND METHODS: Since July 1995, 60 patients fulfilling all eligibility criteria entered this study. All patients received paclitaxel 175 mg/m2 as a three-hour infusion, and carboplatin dosed to an area under the concentration-time curve of seven, every three weeks. No granulocyte colony-stimulating factor was given. Of the 56 male and four female patients, the median age was 57 years (range 29 to 75 years) and the median Eastern Co-Operative Oncology Group performance status was one. Most of the patients had stage IV (34) adenocarcinoma (31) with low differentiation (28). The median number of chemotherapy cycles was three, with a range of one to eight. RESULTS: Of 55 evaluable patients, 15 (27.3%) achieved partial responses, 15 (27.3%) had stable disease, and 25 (45.4%) had progressive disease. The median survival was 8.95 months and 21.6% of the patients survived more than one year. Grade 2/3 nonhematologic toxicity included alopecia (59%), neurotoxicity (3%), and myalgia/arthralgia (10%). Grade 2/3 neutropenia occurred in 14% of patients, whereas grade 3/4 thrombocytopenia was seen in only 4%. One patient died of complications of a severe allergic reaction. CONCLUSION: Combination treatment using paclitaxel and carboplatin is active and well tolerated in patients with inoperable non-small-cell lung cancer. The dose-response relationship to paclitaxel and results of comparison with other platinum-based regimens remain to be determined.

A randomized study of epirubicin monotherapy every four or every two weeks in advanced breast cancer. A Hellenic Cooperative Oncology Group study.

PURPOSE: To evaluate the impact on the response rate in patients with advanced breast cancer (ABC) of the doubling of the dose intensity (DI) of epirubicin monotherapy. PATIENTS AND METHODS: From January 1991 until April 1996, 167 patients with ABC were randomized to receive epirubicin (110 mg/m2) either every four (81 patients, group A) or every two weeks (86 patients, group B). Filgrastim (5 micrograms/kg/daily) was administered prophylactically on days 2-12 of each cycle. RESULTS: The two groups were equally balanced in terms of major patient and tumor characteristics. Even though the median cumulative dose of epirubicin was identical in the two groups (651 mg/m2), the median DI of epirubicin was doubled in group B (27.2 vs. 52.9 mg/m2/wk, respectively). The complete response (CR) rate was significantly increased in group B (5%, 95% CI: 0.16%-9.84% vs. 17%, 95% CI: 8.9%-25.08%, P = 0.011), although overall response rates were similar (49% vs. 53%, P = 0.5957). Also, there was no significant difference in the incidence of grade 3-4 toxicity between the two groups. After a median follow-up of 25 months (range, 0.43-43.3+) no significant difference was observed in the duration of response (median, 10 months vs. 8.5 months, P = 0.5130), time to progression (median, 7.2 months vs. 7.4 months, P = 0.2970) or survival (median, 14.6 months vs. 14.9 months, P = 0.4483). Logistic regression analysis showed that performance status was a significant variable for response (P = 0.0068) and multivariate analysis using the Cox proportional hazards model revealed that performance status was significant for survival (P = 0.0049), while the presence of multiple metastases (P = 0.0020) was significant for time to progression. CONCLUSION: Doubling the planned DI of epirubicin monotherapy significantly increases the CR rate but has no influence on time to progression or survival in patients with ABC.

Paclitaxel by three-hour infusion and carboplatin in advanced carcinoma of nasopharynx and other sites of the head and neck. A phase II study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: Paclitaxel has been demonstrated to have significant activity in recurrent or metastatic head and neck cancer (HNC). In addition, the combination of paclitaxel and cisplatin is active in untreated patients with inoperable HNC. Substitution of carboplatin for cisplatin allows the treatment to be delivered on an outpatient basis. PURPOSE OF THE STUDY: To evaluate the activity and toxicity of the combination of paclitaxel by three-hour infusion and carboplatin as first-line chemotherapy in patients with recurrent or metastatic HNC. PATIENTS AND METHODS: From March 1994 until August 1996, 49 patients with recurrent or metastatic HNC were treated with paclitaxel (200 mg/m2, by three-hour infusion) followed by carboplatin at an AUC of 7 mg.min/ml, every four weeks. G-CSF was administered prophylactically on days 2 to 12 of each cycle. There were 41 men and 8 women with a median age of 57 years (range 23-73). The majority of the patients were symptomatic and they had recurrent disease locoregionally. Fourteen patients had nasopharyngeal cancer (NPC) and 35 had squamous cell cancers of other areas of the head and neck region (non-NPC). RESULTS: At the completion of treatment, two patients with NPC demonstrated complete and six partial responses for an overall response rate of 57% (95% CI 29%-82%). Among patients with non-NPC, the response rate was 23% (95% CI 9%-37%). After a median follow up period of 15 months, the median time to progression was 4.3 months in the non-NPC group and 16.5 months in the NPC group. At the time of the analysis, median survival had not been reached in NPC while it was 7.3 months in non-NPC patients. Grade 3-4 toxicities included anemia (2%) and leukopenia, thrombocytopenia, stomatitis, nausea/vomiting and diarrhea (4% each). CONCLUSIONS: The combination of paclitaxel and carboplatin appears to be well tolerated but only moderately active in patients with advanced non-NPC of the head and neck region. However, its activity appears promising in NPC and deserves further investigation.

5-Fluorouracil, interferon-alpha-2b and cisplatin (FAP) for advanced urothelial cancer. A phase II study. Hellenic Co-operative Oncology Group.

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.

Concurrent radiation and intracarotid cisplatin infusion in malignant gliomas: a feasibility study.

Twenty-two patients with supratentorial malignant gliomas were treated postoperatively with concurrent intracarotid chemotherapy and radiation therapy. There were seven women and 15 men with a median age of 56 years (range, 22-69) and median performance status (Karnofsky score) of 70 (range, 40-90). In all except two cases, histologic studies confirmed malignant glioma. All patients were irradiated with a cobalt 60 equipment. They should have received 45 Gy to the whole brain plus a 15-Gy coned-down boost to the tumor area. Chemotherapy consisted of cisplatin infusion at a dose of 60 mg/m2 on days 2, 22, and 42. Treatment was interrupted in two patients because of progressive disease and voluntary withdrawal in one patient each. In all, 63 courses of cisplatin infusion were administered, all at full dose. Two patients achieved a partial response, and nine had stable disease. Toxicities included nausea/vomiting in nine patients (41%) and transient hemiparesis, confusion, diarrhea, and thrombophlebitis in one patient each. Median time to progression was 26 weeks (range, 4-226+), and median survival was 58 weeks (range, 14-226+). In conclusion, the present study suggests that intracarotid cisplatin administered concurrently with radiation does not improve the therapeutic index in malignant gliomas.

Chemotherapy with methotrexate, vinblastine, epirubicin and carboplatin (Carbo-MVE) in transitional cell urothelial cancer. A Hellenic Co-Operative Oncology Group study.

OBJECTIVES: We conducted a phase II study in order to assess the efficacy and toxicity of Carbo-MVE (carboplatin 250 mg/m2 i.v. day 1, methotrexate 25 mg/m2 i.v. days 1, 15 and 22, vinblastine 2.5 mg/m2 i.v. days 1, 15 and 22 and epirubicin 25 mg/m2 day 1). The regimen ws to be repeated every 28 days. METHODS: Forty-six patients with transitional cell carcinoma of the bladder entered the study. Patients with metastatic disease were treated for 6 cycles, while patients with locally advanced or locoregional disease had 4 cycles of induction chemotherapy followed by cystectomy or radiotherapy. RESULTS: Toxicity was generally mild and treatment well tolerated. The overall response rate was 54.4%, with 26% complete and 28.3% partial response rates. The median survival was 17.5 months with the complete responders to live significantly longer (64.82 months) than those who had a partial response (20.5 months), stable disease (15 months) or progressive disease (8.5 months). Survival was also significantly longer in patients with good performance status as well as in patients with locally advanced or locoregional disease. Finally, patients who had cystectomy as definitive treatment survived significantly longer (32 months) than those who had been irradiated (16 months). CONCLUSIONS: The Carbo-MVE regimen appears to be an effective and well-tolerated treatment in patients with transitional cell carcinoma of the bladder.

Paclitaxel and carboplatin in recurrent or metastatic head and neck cancer: a phase II study.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) appears to be one of the most active drugs in the treatment of advanced head and neck cancer. The maximum tolerated dose of paclitaxel in combination with carboplatin is currently being evaluated in phase I/II studies. We designed a phase II study to evaluate the activity and acute and cumulative toxicity of this combination in patients with recurrent or metastatic cancer of the head and neck. Chemotherapy consisted of paclitaxel 200 mg/m2, given as a 3-hour infusion, and carboplatin dosed to an area under the concentration-time curve of 7 mg x min/mL, administered every 28 days. Granulocyte colony-stimulating factor (5 microg/kg) also was given on days 2 to 12 of each cycle. At the time of this report, 41 patients had entered this study. Primary sites included the nasopharynx (10 patients), larynx (18), oral cavity (three), oropharynx (six), hypopharynx (three), and unknown (one). Among 25 evaluable patients with non-nasopharyngeal cancer, there were two complete responses and three partial responses, for an overall response rate of 20% (95% confidence interval, 4% to 36%). Among eight evaluable patients with nasopharyngeal cancer, four achieved a complete response and two a partial response. Grade 3 to 4 toxicities included anemia (2.5%), leukopenia (7.5%), thrombocytopenia (5%), vomiting (5%), stomatitis (2.5%), and infection (5%). These preliminary data indicate that the combination of paclitaxel and carboplatin is active against advanced head and neck cancer, particularly when used in the treatment of nasopharyngeal cancer.
