Paclitaxel in combination with carboplatin or gemcitabine for the treatment of advanced head and neck cancer.

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.

Prognostic variable in patients with advanced colorectal cancer treated with fluorouracil and leucovorin-based chemotherapy.

Possible prognostic variables for tumor response, time to progression (TTP), and survival in 141 patients with advanced colorectal cancer treated with fluorouracil and leucovorin-based chemotherapy were analyzed. None of the variables examined for their possible influence on tumor response attained significance in the stepwise logistic regression. In the univariate analysis, variables found to be strongly associated with TTP were performance status (PS) (P = 0.0301), liver involvement (P = 0.030), and the initial values of WBC (P = 0.0319), lactic dehydrogenase (LDH; P = 0.0053), gamma-glutamyl-transpeptidase (gamma-GT; P = 0.0013), alkaline phosphatase (ALP; P = 0.0186), albumin (P = 0.0004), and carcinoembryonic antigen (CEA; P = 0.0014). In the Cox analysis, liver involvement (P = 0.0553), albumin (P = 0.0181), PS (P = 0.484), and ALP (P = 0.0553) were retained as independently significant variables. When only patients with liver metastases were included in the analysis, then only albumin (P < 0.001) demonstrated a prognostic significance. Also, in the univariate analysis, variables predicting survival were PS (P = 0.0230), grade (P = 0.00600), liver involvement (P = 0.0002), LDH (P = 0.0001), gamma-GT (P < 0.001), ALP (P = 0.0006), albumin (P = 0.0309), and CEA (P = 0.005). With the multivariate analysis, gamma-GT (P = 0.0004), albumin (P = 0.0634), and CEA (P = 0.0804) were selected as significant. In those patients who presented with liver involvement, variables predicted survival were gamma-GT (P = 0.0041), albumin (P = 0.0442), and the percentage of involved liver parenchyma (P = 0.0690). These results could be helpful for the stratification of future trials in advanced colorectal cancer.

Elemental composition of bone minerals in women with breast cancer treated with adjuvant tamoxifen.

Oestrogen levels play a major role in conditioning the rates of bone changes in women. Tamoxifen is a synthetic oestrogen antagonist commonly used as an adjuvant therapy for breast cancer. The goal of the present study was to study the amount and the elemental composition of bone minerals in the appedicular skeleton of women with breast cancer treated with adjuvant tamoxifen, as well as to investigate the possibility of increased risk for osteoporosis. Forty-two patients, aged 41-65 years, without skeletal metastases were studied. The mean duration of tamoxifen administration on a daily dose of 20 mg was 21 months (range 1-59 months). It was found that neither the amount of phosphorus in hands (HBP) nor forearm bone mineral content (BMC) differ statistically from those of age-matched healthy subjects. This was confirmed by reassessing bone mineral status after 30 months in 17 postmenopausal patients treated with tamoxifen for a mean time of 52 months. In conclusion, our data support that long-term tamoxifen treatment has no adverse or protective effect on the amount and elemental composition of the appedicular skeleton.

Carboplatin alone compared with its combination with epirubicin and cyclophosphamide in untreated advanced epithelial ovarian cancer: a Hellenic co-operative oncology group study.

We compared, in a multicentric randomised prospective study, the efficacy and toxicity of carboplatin 400 mg/m2 as a single agent (CB) to a combination of carboplatin 300 mg/m2, epirubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 (CB-EC) in advanced ovarian cancer patients. The treatment was scheduled to be administered every 3 weeks for six courses. Following initial laparotomy and cytoreductive surgery, 130 previously untreated patients entered the study. 73 patients were treated with carboplatin alone while 57 received the combination chemotherapy. In the majority of the patients, the regimens had to be given every 4 weeks due to myelosuppression. Nausea, vomiting and alopecia were more severe in the CB-EC arm. Overall, clinical complete response was observed in 73 (56%) and partial response in 20 (15%) patients. The median time to progression was 16.89 months and median survival was 29.54 months. No significant differences in response rate, time to progression, disease-free survival and overall survival were observed between the two treatment arms. The prognostic role of residual disease after initial surgery, complete remission at second-look laparotomy, tumour stage and performance status was confirmed.

EO9 phase II study in advanced breast, gastric, pancreatic and colorectal carcinoma by the EORTC Early Clinical Studies Group.

In a phase II trial, the activity of EO9, a new bioreductive alkylating agent, was assessed. EO9 was used as second-line chemotherapy in breast cancer patients and as first-line chemotherapy for patients with gastric, pancreatic and colorectal cancer. EO9 was given as a 5 min i.v. infusion at a weekly dose of 12 mg/m2. 92 patients were entered; 22 with breast cancer, 26 with colon cancer, 24 with pancreatic cancer and 20 with gastric cancer. In general, the drug was well tolerated with nausea and vomiting occurring in 26.42 and 13.3% of courses, respectively. Reversible proteinuria was the main toxicity occurring in 45% of courses. Antitumour activity was not observed. At this dose and schedule, EO9 is not an active drug in the type of tumour studied.

Multicentre phase II pharmacological evaluation of rhizoxin. Eortc early clinical studies (ECSG)/pharmacology and molecular mechanisms (PAMM) groups.

Rhizoxin is a macrocyclic lactone compound that binds to tubulin and inhibits microtubule assembly. Rhizoxin demonstrated preclinical anti-tumour activity against a variety of human tumour cell lines and xenograft models. Phase I evaluation found a maximum tolerated rhizoxin dose of 2.6 mg m-2, with reversible, but dose-limiting, mucositis, leucopenia and diarrhoea. Clinical trials were then initiated by the EORTC ECSG in melanoma, breast, head and neck, and non-small-cell lung cancers with the recommended phase II rhizoxin dose of 2 mg m-2. Pharmacological studies were instituted with the phase II trials to complement the limited pharmacokinetic data available from the phase I trial. Blood samples were obtained from 69 of 103 eligible patients enrolled in phase II rhizoxin studies, and these were evaluable for pharmacokinetic analysis in 36 patients. Plasma rhizoxin concentrations were determined by high-performance liquid chromatography (HPLC), and post-distribution pharmacokinetic parameters were estimated by a one-compartment model. Rhizoxin was rapidly eliminated from plasma, with a median systemic clearance of 8.41 min-1 m-2 and an elimination half-life of 10.4 min. Rhizoxin area under the concentration-time curve (AUC) was higher in patients obtaining a partial response or stable disease than in those with progressive disease (median 314 vs 222 ng ml-1 min; P = 0.03). As predicted from previous studies, haematological and gastrointestinal toxicity was observed, but could not be shown to be related to rhizoxin AUC. This study demonstrated the rapid and variable elimination of rhizoxin from the systemic circulation. The presence of pharmacodynamic relationships and the low level of systemic toxicity suggest that future trials of rhizoxin with alternative dosage or treatment schedules are warranted.

Phase II clinical trials with rhizoxin in breast cancer and melanoma. The EORTC Early Clinical Trials Group.

Rhizoxin is a new anti-tumour agent isolated from the pathogenic fungus Rhizopus chinensis. It has shown broad activity against murine tumour models and is also active against vinca alkaloid-resistant cells. The purpose of our studies was to determine the clinical activity of this compound in patients with advanced breast cancer and melanoma. Based on the results of a phase I study, 2.0 mg m-2 was administered as intravenous infusion over 5 min every 21 days. Nineteen patients were entered into the breast cancer phase II trial and received a total of 50 courses (median 2, range 1-6). Of these, dose reductions were performed in three courses because of leucopenia or stomatitis (1.5 mg m-2, one course; 1.45 mg m-2, two courses). Twenty-six patients were entered into the melanoma trial and received a total of 70 courses (median 2, range 1-12). No dose reductions were required. All patients were eligible for toxicity. Haematological toxicity included neutropenia CTC grade 3 (29/120 courses, 24.2%) and grade 4 (11/20 courses, 9.2%). Only drug-related CTC grade 1 thrombocytopenia was observed. Non-haematological toxicity included alopecia in all patients after two courses of treatment as well as CTC grade 3/4 stomatitis and asthenia. In the breast cancer study, one patient achieved a more than 50% tumour reduction after six cycles but was progressing after 6 weeks. Another patient showed a partial remission after the first course but was taken off the study because of CTC grade 3 skin toxicity. One patient was not evaluable for response (early death). No objective remissions were observed in 15 evaluable patients. In melanoma, no objective remissions were observed. We conclude that rhizoxin can be safely administered at 2.0 mg m-2 every 3 weeks. However, it has little activity in patients with advanced breast cancer and melanoma.

Single agent activity of rhizoxin in non-small-cell lung cancer: a phase II trial of the EORTC Early Clinical Trials Group.

In a multicentre trial of the EORTC-Early Clinical Trials Group (ECTG) we treated 31 chemotherapy-naive patients with advanced non-small-cell lung cancer (NSCLC) with rhizoxin, a novel tubulin-binding agent. The drug was given as an i.v. bolus injection at 2 mg m-2 once every 3 weeks in an outpatient setting. Prophylactic antiemetics were not routinely given. Of the 29 eligible patients, nine had been treated surgically and three had received radiotherapy. The main toxic effects observed were stomatitis (34% of cycles) and neutropenia (41% of cycles). Neutropenic fever was rare (3% of cycles). Twenty-seven patients were evaluable for response. There were four partial responses (15%), while 13 patients (48%) showed stabilisation of their disease. The median duration of response was 7 months (range 6.0-10.7 months) and median survival from the start of rhizoxin treatment was 6 months (range 2-14.7 months). Rhizoxin as single agent shows activity in patients with advanced NSCLC.

A prospective randomized phase III study in non-small-cell lung cancer comparing cisplatin, ifosfamide, vinblastine (VIP) versus cisplatin, ifosfamide and etoposide (VIP-16). Hellenic Co-Operative Oncology Group.

BACKGROUND: It was recently reported that when ifosfamide was added to cisplatin and vinblastine the response rate was increased but not the survival in patients with non-small-cell lung cancer (NSCLC). The purpose of this study was to investigate the possibility of increased responses and survival with use of the combination of cisplatin, ifosfamide, etoposide (VIP-16) in comparison to the combination of cisplatin, ifosfamide, vinblastine (VIP) in non-operable NSCLC. PATIENTS AND METHODS: Two hundred twelve patients with histologically confirmed diagnoses of NSCLC were randomized into two groups: group A received cisplatin 100 mg/ m2, vinblastine 6 mg/m2 and ifosfamide 3 mg/m2 i.v. on day 1 every 3 weeks; group B received the same regimen except that etoposide 120 mg/m2 was substituted for vinblastine on days 1, 2, and 3. Patients were well balanced for age, sex, performance status (PS), stage, grade, histology and sites of disease, and the relative dose intensity was similar in both groups. RESULTS: One hundred one patients were evaluable for response in group A and 99 in group B. The overall response rates were 29% in group A (5CR) and 25% in group B (3CR). The median time to progression was 7.51 (2-35) months for group A and 7.7(1-28) months for group B (P = 0.34). The median survival was 8.49 (0.33-37.44) months for group A and 9.38 (0.43-36.59) for group B (P = 0.39). Multivariate Cox stepwise analysis showed stage to be the only significant prognostic factor for survival (P = 0.0114). Toxicity was not remarkable and not different between the two groups except for alopecia which was much more common in the patients who received etoposide. CONCLUSION: VIP and VIP-16 combination chemotherapies are equally active in NSCLC with acceptable toxicity. Stage proved to be the most significant prognostic factor for survival in this study.

A randomized phase II study with two schedules of the novel indoloquinone EO9 in non-small-cell lung cancer: a study of the EORTC Early Clinical Studies Group (ECSG).

In a multicentre randomized trial of the EORTC-ECSG, we have treated 38 chemotherapy naïve patients with advanced non-small-cell lung cancer (NSCLC) with EO9, a novel bio-reductive alkylating indoloquinone. The drug was given at two different dose schedules by a single bolus i.v. injection: arm A 12 mg/m2 weekly and arm B 22 mg/m2 every three weeks. All together 185 courses were administered (145 in arm A and 40 in arm B). The major toxicity was reversible proteinuria more frequently occurring in the three-weekly schedule (arm A 34.5% vs. arm B 62.5%). Creatinine elevation, fluid retention and pericardial or pleural effusion were also recorded in a limited number of patients. Other common toxicities more frequent in the three-weekly administration were asthenia (21% vs. 35% of cycles), nausea (15% vs. 27.5% of cycles) and vomiting (5% vs. 17.5% of cycles). Toxicities were mainly of grade I and II. No responses have been observed. Five patients (26%) on arm A and eight (53%) on arm B experienced stable disease. These doses and schedules of EO9 do not yield activity in NSCLC.

Recombinant interferon ALFA-2A in combination with carboplatin, vinblastine, and bleomycin in the treatment of advanced malignant melanoma.

Thirty-four patients with advanced malignant melanoma were treated with recombinant alpha-interferon (IFN) and chemotherapy consisting of carboplatin, vinblastine, and bleomycin (CVB). CVB was given for four cycles and IFN for 1 year or until progression. Of the 34 analyzed patients, 17 (50%) achieved an objective response, including two complete (6%) and 15 partial responses (44%). Responses were noted in cutaneous, lymph node, and pulmonary sites, with a median time to disease progression of 5 months (range, 3-20 months). The median survival from onset of therapy was 8 months (range, 1-22 months) for the 34 patients. Ninety-four percent of the patients experienced flu-like symptoms and 82% fatigue or weakness. Leukopenia grade 3-4 was observed in four patients (12%). There were two toxicity-related deaths (6%); one from bleomycin-induced pneumonitis and one from neutropenic sepsis. It is concluded that the addition of IFN to CVB regimen, in this study, showed no apparent advantage on response rates, disease-free interval, or survival. The observed treatment-related mortality was unacceptably high. IFN administered as maintenance therapy following CVB conferred no survival benefit.

Clinical value of CA 15-3, mucin-like carcinoma-associated antigen, tumor polypeptide antigen, and carcinoembryonic antigen in monitoring early breast cancer patients.

A total of 209 postsurgical breast cancer patients were prospectively monitored with simultaneous serum level estimations of CA 15,3, mucin-like carcinoma-associated antigen (MCA), tumor polypeptide antigen (TPA), and carcinoembryonic antigen (CEA); 141 (67.5%) were free of recurrence and 68 (32.5%) developed metastases during the follow-up. The mean values of tested tumor markers differed significantly in those with progressive disease compared with those free of disease recurrence. The sensitivity of tumor markers were CA 15-3, 68.2%; CEA, 34.1%; MCA, 72.7%; and TPA, 72.7%. The combination of CA 15-3 with TPA or MCA with TPA showed a trend for improved sensitivity of both markers (p = 0.06), with no specific loss of specificity (p = 0.11). The addition of CEA to CA 15-3 or MCA does not provide additional information for clinical evaluation. Patients with elevated tumor marker determinations had significantly shorter survival than those with values within the normal range. Two serial, progressively increasing values of tumor markers during the follow-up strongly predict recurrence. This study indicates that the comeasurement of CA 15-3 with TPA or MCA with TPA is justifiable in monitoring breast cancer patients postoperatively.

Fluorouracil and leucovorin with or without interferon alfa-2b in advanced colorectal cancer: analysis of a prospective randomized phase III trial. Hellenic Cooperative Oncology Group.

PURPOSE: To investigate if double modulation of fluorouracil (5-FU) with leucovorin (folinic acid [FA]) and interferon alfa-2b (IFN 2b) improves responses and survival in comparison to single modulation of 5-FU with FA. PATIENTS AND METHODS: One hundred six patients with histologically confirmed advanced colorectal cancer, measurable disease, and without previous chemotherapy were prospectively randomized into two groups. Patients in group A received 5-FU 450 mg/m2 as an intravenous bolus in the midinfusion of FA weekly. FA was given at a dose of 200 mg/m2 in 500 mL 0.9% normal saline solution in 2-hour infusion. Patients in group B received exactly the same regimen plus IFN 2b 5 million units subcutaneously three times weekly. RESULTS: All patients were well balanced in both groups regarding age, sex, performance status, number, and site of metastasis. One hundred two patients were assessable. All patients have died. There was no difference in response between the two groups (7.8% v 9.8%). Median survival was 10.1 months in group A, and 7.2 months in group B (P = .00189). Median time to progression was 8.4 and 5.2 months, respectively (P = .00196). Overall, better performance status and older age had a positive impact on survival. Toxicity was the most important and catastrophic aspect of this study. Patients who received IFN 2b had significantly worse anemia, neutropenia, diarrhea, anorexia, weight loss, flu-like syndrome, and psychological reactions. CONCLUSION: Based on this final analysis, the addition of IFN 2b to the combination of 5-FU and FA enhances toxicity and contributes to decreased survival.

High-dose epirubicin and r-met-hu G-CSF (filgrastim) in the treatment of patients with advanced breast cancer: A Hellenic Cooperative Oncology Group study.

The delivery of high-dose epirubicin in patients with advanced breast cancer usually entails serious myelotoxicity and frequent treatment delays. Concurrent administration of G-CSF probably allows the administration of epirubicin on schedule with minimal morbidity. From August 1990 to February 1992, 42 women with advanced breast cancer were treated with six cycles of epirubicin 110 mg/m2 every 4 weeks. Filgrastim 5 micrograms/kg per day for 14 days was administered subcutaneously starting 24 hours after chemotherapy. All patients had multiple metastatic sites, and 39 had visceral metastases. All cases were evaluable for response, toxicity, and survival. Treatment was delayed in only two cases. The actually administered average dose per unit time per patient amounted to 99.6% of the dose prescribed by the protocol. Two (4.5%; 95% confidence interval [C.I.] 0-16%) patients demonstrated a complete response and 14 (33%; 95% C.I. 19-49%) a partial response. Median time to progression was 31 weeks and median survival was 60 weeks. Severe granulocytopenia was seen in six patients; stomatitis and diarrhea in one patient each. Myoskeletal pain was noticed in 23 (55%) patients, while cardiac problems were reported in 3 cases. The present study shows that the prophylactic use of r-met-hu G-CSF allows the administration of high-dose epirubicin every 4 weeks with minimal morbidity and an improved quality of life.

Evaluation of six tumor markers in patients with carcinoma of unknown primary.

We have retrospectively evaluated six serum tumor markers in 85 patients with carcinoma of unknown primary. The serum levels of carcinoembryonic antigen (CEA), CA 19-9, CA 15-3, CA 125, beta-chorionic gonadotropin (beta-HCG) and alpha-fetoprotein (AFP) were related with the histological pattern (undifferentiated carcinoma or adenocarcinoma), the number and the site of metastases, as well as the response to chemotherapy and the patients' survival. More than 40% of the patients had increased serum levels of all six tumor markers, except of AFP which was found to be increased in only 17% of them. Increased levels of CA 19-9 were related to metastatic adenocarcinoma, whereas CA 19-9 and CA 15-3 had a relationship with more advanced disease. Patients with liver involvement had higher mean levels of CEA and CA 19-9 as compared to those with nodal disease. None of these markers was found to have a predictive value for response to chemotherapy or survival. Although the present study has a retrospective nature, it allows us to conclude that patients with CUP have a nonspecific over-expression of the above serum tumor markers and that routine use of these markers does not offer any diagnostic or prognostic assistance.

Combination chemotherapy with cisplatin-vinblastine in malignant mesothelioma.

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.

The value of neuroendocrine markers in non-small cell lung cancer: a comparative immunohistopathologic study.

In order to estimate the value of immunohistochemical identification of neuroendocrine (NE) differentiation markers in non-small cell lung carcinomas (NSCLCs), we investigated the expression of five neuroendocrine and neural differentiation-related antigens in 51 NSCLCs. Additionally, 20 epithelial lung tumors with NE differentiation [15 carcinoids and five small cell lung carcinomas (SCLCs)] and 61 epithelial tumors of various other origin (breast, prostate, colon and head-neck carcinomas) were studied. An indirect two-stage immunoperoxidase method was performed in formalin-fixed and paraffin-embedded tissue specimens, by using commercially available monoclonal antibodies. These antibodies are directed against neuron-specific enolase (NSE), chromogranin-A and Leu-7 which are general markers of NE differentiation, bombesin, which is a specific NE secretory product and neurofilament triplet protein (NFTP), an intermediate filament protein of neuronal differentiation. All five markers demonstrated a positive immunoreactivity in NSCLCs, equally distributed to all three histologic subtypes, ranging from 16 to 47% of the cases (NSE 47%, bombesin 21.5%, Leu-7 21.5%, chromogranin-A 18% and NFTP 16%). Most of the carcinoids and SCLCs expressed multiple or all NE markers. The other four epithelial tumors showed a positive immunoreactivity for bombesin, Leu-7 and NFTP, ranging from 11 to 40% of the cases. Chromogranin-A was not expressed in any of these tumors, whereas NSE was demonstrated only in 17% of breast carcinomas. The following remarks can be drawn from this study: (1) some NSCLCs showed immunophenotypic NE differentiation; (2) among all the markers used, NSE was the most sensitive (sensitivity, 100%) and chromogranin-A the most specific (specificity, 100%); and (3) NSE and chromogranin-A appear to be the most valuable and useful indicators of probable neuroendocrine differentiation in lung epithelial tumors.

Intensive chemotherapy with high-dose epirubicin every 2 weeks and prophylactic administration of filgrastim in advanced breast cancer.

50 women with advanced breast cancer were treated with an intensified regimen which consisted of high-dose epirubicin (110 mg/m2) every 2 weeks and filgrastim (5 micrograms/kg) subcutaneously for 13 days, starting 24 h after chemotherapy. 44 patients completed all six cycles. The median interval between cycles of treatment was 14.3 days. The actually administered median dose per unit time per patient was 53 mg/m2/week, amounting to 97.2% of the dose prescribed by the protocol. 7 [14%, 95% confidence interval (C.I.) 4-24%] patients achieved a complete and 25 (50%, 95% C.I. 36-64%) a partial response. Median time to progression was 32 weeks and median survival 64 weeks. Stomatitis and fever each occurred in 7 (14%) patients. Grade 3 haematological toxicity was observed in 6 (12%) patients. 1 (2%) patient developed grade 4 cardiac toxicity. This intensified regimen appears to be a well tolerated and effective treatment in advanced breast cancer.
