Prevention of chemotherapy-induced alopecia using an effective scalp cooling system.

Alopecia is a distressing side-effect of cancer treatment. Taxanes (TX), anthracyclines (ANR) and etoposide (ET) have been consistently associated with significant alopecia. We studied an effective scalp cooling system, the Penguin Cold Cap system, for the prevention of chemotherapy-induced alopecia in 70 patients receiving chemotherapy, including one of the following major alopecia-causing agents: Group A, TX-based regimes (without ANR); Group B, TX+ANR; Group C, ANR-based regimes (without TX); Group D, ET-based regimes. Protection from hair loss was achieved by maintaining scalp temperatures below 15 degrees C before, during and after chemotherapy by frequent changing of the caps. Assessment was carried out using a grading system from 0 to 4. Grades 0-2 were considered as satisfactory hair protection, whilst Grades 3-4 were considered failures. 57 patients were evaluable for assessment. An overall 81% protection was achieved. In groups C and D 11 of 12 patients (92%) had no alopecia, whilst 30 of 34 patients (88%) treated with taxanes had adequate hair protection. In Group B, 4 of 11 patients (36%) had adequate hair protection. The system was well tolerated and is a very effective method for protection from hair loss caused by TX, ANR and ET. Our results are comparable with and, in most cases, better than those reported in other studies using various alopecia preventive methods.

Ifosfamide plus oral etoposide salvage chemotherapy for platinum-resistant paclitaxel-pretreated ovarian cancer.

BACKGROUND: The prognosis of platinum resistant ovarian cancer is very poor and the treatment of choice has not been clearly defined. PATIENTS AND METHODS: We conducted a phase II study with the combination of ifosfamide i.v. at 2.25 g/m2 (days 1, 2) and etoposide per os at 100 mg daily (days 1-10) every four weeks. To be eligible for the study patients had to be resistant to platinum and paclitaxel pretreated. RESULTS: Forty-one patients entered the study. The median interval from the previous chemotherapy was 3.9 months. The median number of previous chemotherapeutic regimens was 2. Severe toxicities included neutropenia (41% of patients), leukopenia (29%) and thrombocytopenia (13%). Thirty-five patients are assessable for response. Nine patients responded (22% of the eligible, 26% of the assessable), four of them demonstrated complete response to chemotherapy (10% and 12%, respectively), while three patients demonstrated stabilization of their progressive disease. After a median follow-up of 18 months, time to progression is 3 months (range 0.9-14.4), duration of response is 9 months (2.5-11) and median survival is 13 months (2.5-37.4+). CONCLUSIONS: The combination of ifosfamide with oral etoposide appears to have significant but manageable toxicity and encouraging efficacy in platinum resistant ovarian cancer.

Gemcitabine and vinorelbine as second-line treatment in patients with metastatic breast cancer progressing after first-line taxane-based chemotherapy: a phase II study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: Gemcitabine and vinorelbine have shown activity in breast cancer. A phase II trial was initiated in order to evaluate the response rate (RR) and time to progression (TTP) of the combination of the two drugs in patients with metastatic breast cancer progressing after first-line taxane-based chemotherapy. PATIENTS AND METHODS: Thirty-one patients were treated with the combination of gemcitabine 1000 mg/m2 days 1 + 8 and vinorelbine 30 mg/m2 days 1 + 8. The cycles were repeated every three weeks. RESULTS: Of 27 evaluable patients 1 (4%, 95% confidence interval (95% CI): 0.1%-19%) achieved complete remission (CR), five (18%; 95% CI: 6%-38%) partial remission (PR), eleven (40%; 95% CI: 22%-61%) stable disease and ten patients progressed. The median duration of response was six months (range 4-10+) and the median duration of disease stabilization was five months (range 2-22+). With a median follow-up of 16 months (range 0.4-22+) the median TTP was 3.5 months (range 0.4-22+) and the median survival was 9.5 months (range 0.4-22+). Grade 3-4 toxicities were granulocytopenia 15 patients (48%), rash 3 patients (10%), neuropathy 1 patient (3%) and thrombocytopenia 1 patient (3%). In conclusion the combination of gemcitabine/vinorelbine in the doses administered in this group of patients had a response rate of 22% and needs to be further evaluated in metastatic breast cancer.

Activity and toxicity of GI147211 in breast, colorectal and non-small-cell lung cancer patients: an EORTC-ECSG phase II clinical study.

BACKGROUND: GI147211 is a water-soluble synthetic analogue of camptothecin showing promising in vivo and in vitro antitumor activity and an acceptable toxicity profile. PATIENTS AND METHODS: Between April 1995 and November 1996, 67 eligible patients with pretreated breast cancer (25 patients) and chemo-naïve colorectal (19 patients) and non-small-cell lung cancer (23 patients) were entered into three multicentric, non-randomized phase II trials. Treatment schedule consisted of intravenous GI1147211 administered at a dose of 1.2 mg/m2/day for five consecutive days every three weeks. RESULTS: Hematological toxicity was common with grade 3-4 neutropenia in 54% of patients and neutropenic fever together or not associated with infection in 14.5% of patients. Grade 3-4 thrombocytopenia and grade 2-4 anemia were observed in 20% and in 68% of patients, respectively. Non-hematological toxicity was generally mild to moderate and consisted mainly of gastrointestinal toxicity, asthenia and alopecia. A dose-escalation to 1.5 mg/m2/d was feasible in 17 (25%) patients. The antitumor activity of GI1147211 was moderate in breast cancer patients (3 partial responses (PRs), response rate (RR) 13%) and minimal in non-small cell lung cancer patients (2 PRs, RR 9%). No objective responses were obtained in colorectal patients. CONCLUSIONS: GI147211, at the dose and schedule employed in this study, showed an acceptable safety profile but a modest antitumor activity in the examined tumor types.

Paclitaxel (175 mg/m2) plus carboplatin (6 AUC) versus paclitaxel (225 mg/m2) plus carboplatin (6 AUC) in advanced non-small-cell lung cancer (NSCLC): a multicenter randomized trial. Hellenic Cooperative Oncology Group (HeCOG).

PURPOSE: The combination of paclitaxel and carboplatin has become a widely used regimen in NSCLC due to phase II reports of moderate toxicity, reasonable activity and easy outpatient administration. Purpose of our present prospective study was to evaluate the dose response relationship of paclitaxel. PATIENTS AND METHODS: Since July 1996, 198 patients with non-operable NSCLC and measurable disease without previous chemotherapy entered the trial. Ninety nine patients (group A) were randomized to receive paclitaxel 175 mg/m2 in three-hour infusion plus carboplatin dosed to an area under the concentration-time curve of 6 every 3 weeks and 99 (group B) to receive the same regimen with paclitaxel increased to 225 mg/m2. Eligibility criteria included WHO performance status 0-2, documented inoperable stage IIIA and IIIB, IV, no brain metastasis, no prior chemotherapy and adequate renal and hepatic function. Patients in both groups were well-matched with baseline disease characteristics. RESULTS: In group A with 90 evaluable patients, the response rate was 25.6% (6 CR, 17 PR) whereas in group B with 88 evaluable patients, the response rate was 31.8% (3 CR, 25 PR), P = 0.733. Median time to progression favored the high-dose paclitaxel (4.3 vs. 6.4 months, P = 0.044). The median survival was 9.5 months for group A versus 11.4 months for group B (P = 0.16). The one-year survival was 37% for group A and 44% for group B (P = 0.35). The best prognostic factor for one-year survival was the response rate (P < 0.0001). With a relative dose intensity of paclitaxel 0.94 in both groups, neurotoxicity (P = 0.025) and leucopenia (P = 0.038) were more pronounced in group B patients. No toxic death was observed. CONCLUSIONS: Higher dose paclitaxel prolongs the median time to progression but causes more neurotoxicity and leucopenia. The better response rate, the longer overall and better one-year survival seen with the higher dose of paclitaxel are not statistically significant.

Fluorouracil and leucovorin with or without interferon alfa-2a as adjuvant treatment, in patients with high-risk colon cancer: a randomized phase III study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: It has been shown in randomized studies that adjuvant treatment with the combination of fluorouracil (FU) and levamisole reduced the risk of recurrence and deaths of patients with stage III colon cancer. Pharmacological studies of FU led to its use in combination with a number of modulating agents including interferon-alpha and leucovorin (LV) that appear to enhance its activity in vitro. Furthermore, a meta-analysis suggested that the combination of FU with LV increased the response rate as compared to FU monotherapy in patients with advanced colorectal cancer. PURPOSE: To evaluate the impact of adjuvant treatment with the combination of FU and LV with or without interferon alfa-2a (IFN) on disease-free survival (DFS) and overall survival (OS) for patients with stage II or III colon cancer. PATIENTS AND METHODS: From August 1989 to July 1997, 280 patients with stage II and III colon cancer entered the study and were randomly assigned to receive either the combination of FU (600 mg/m(2)/week x 6, followed by a 2-week rest) and LV (500 mg/m(2)/week x 6 as a 2-hour infusion, followed by a 2-week rest) for 4 cycles (group A, 139 patients), or the same chemotherapy plus recombinant IFN (3 MU subcutaneously 3 times a week) for 1 year (group B, 141 patients). RESULTS: A total of 109 patients (78.9%) of group A and 119 (84.4%) of group B completed four cycles of chemotherapy. Also, 51.4% of patients of group A and 53.9% of group B received > or =80% of the planned dose of FU. One patient (group A) was found to be ineligible and was not included in the analysis. The median relative dose intensity of FU in the two groups was 0.90 and 0.85, respectively. As of August 1998, after a median follow up of 4 years, there was no significant difference in either 3-year DFS (group A, 83.1%; group B, 75.9%, p = 0.14) or OS (group A, 84.5%; group B, 80.0%, p = 0.27). In the Cox model, stage of disease, number of infiltrated nodes, tumor grade and presence of regional implants were identified as significant prognostic factors for OS. Grade 3-4 toxicities, mainly diarrhea, were observed in 26.1% of patients of group A and in 24.8% of group B. There were no treatment-related deaths. CONCLUSIONS: The addition of IFN to the combination of FU with LV postoperatively does not improve DFS and OS of patients with stage II or III colon cancer.

Anthracycline-based chemotherapy of primary non-Hodgkin's lymphoma of the testis: the hellenic cooperative oncology group experience.

Testicular non-Hodgkin's lymphoma is an uncommon disease and its outcome following chemotherapy and/or radiotherapy has been variable. A retrospective analysis was performed on 26 patients with primary testicular lymphoma treated predominantly with anthracycline-based chemotherapy between 1984 and 1999. The patients' median age was 60 years (range 19-82 years) with 17 (65.4%) patients being older than 60 years. Four (15.4%) patients had constitutional B symptoms. There were 11 (42.3%) patients with high grade lymphoma, 12 (46.2%) with intermediate grade, 1 (3.8%) with low grade and 2 (7.7%) were not classified. According to the Ann-Anbor staging system, 18 patients (69.2%) had early (stage I/II) and 8 (30.8%) advanced (stage III/IV) disease. Chemotherapy was administered to 24 patients including 22 patients who received anthracycline-based chemotherapy. Two stage IEA patients were treated with orchidectomy and adjuvant radiotherapy to the regional lymph nodes without systemic chemotherapy. Chemotherapy alone resulted in a complete remission (CR) in 14 (58.3%) of 24 patients and partial remission in 1 (4.2%), amounting to an overall response rate (RR) of 62.5%. Of the 5 stage I patients who had chemotherapy on an adjuvant basis, 4 (80%) had CR/no evidence of disease. Of the 11 stage II patients, 8 (72.7%) achieved CR and 1 (9.1%) PR (overall RR of 81.8%). CR was obtained in 2 (25%) of 8 stage III/IV patients. Both patients remain disease free for 26 and 65 months. Excluding the 5 stage I patients, chemotherapy resulted in a CR in 10/19 (52.6%) patients and a PR in 1/19 (5.2%), inducing an overall RR of 57.8%. The mean duration of response was 75 months (range 8-145.5+ months). After a median follow-up of 87 months (range 0.13-145.5+ months) the median survival time was 31 months (range 0.13-145.5+ months) and the median time to progression (TTP) 17 months (range 0.13-145.5+ months). The median TTP was significantly higher in early disease compared to that of advanced disease (52 vs. 3 months, p = 0.02). Of the 3 patients who relapsed following disease-free status, CNS involvement occurred in 2 stage II patients and contralateral testis involvement in 1 stage IEA, respectively. The latter remained disease free for 2 years following orchidectomy alone. The other 2 patients who relapsed did not respond to salvage chemotherapy and died. There was no significant relationship between the values of LDH and beta(2)-microglobulin with the outcome except for ESR which was significantly related with the CR (p = 0.005) or RR (p = 0.005). In conclusion, patients with primary testicular lymphoma have a poor outcome, despite the treatment with anthracycline-containing regimens. Treatment with anthracycline-based chemotherapy is recommended in patients at early stages. In advanced disease, more intensive or investigational regimens should be considered. Because the relapse rate in the CNS and contralateral testis is quite high in most studies, prophylactic CNS treatment and radiotherapy to the other testis should be included in the management of testicular lymphoma.

Chemotherapy-induced noncardiogenic pulmonary edema related to gemcitabine plus docetaxel combination with granulocyte colony-stimulating factor support.

Several cancer therapeutic agents have been associated with pulmonary toxicity. Herein, we describe the case of a 73-year-old woman with breast cancer metastatic to the liver, who developed noncardiogenic pulmonary edema (NPE) while on treatment with gemcitabine plus docetaxel combination with granulocyte colony-stimulating factor (G-CSF) support. Gemcitabine, a deoxycytidine analogue, is reported to produce mild self-limiting and only occasionally severe pulmonary toxicity. The microtubule stabilizer docetaxel has been associated with water retention complications. The combination of these two agents has shown promising activity in several solid tumors and is in a phase of clinical development with prophylactic G-CSF in most of the trials due to the high rate of dose-limiting neutropenia observed with this combination. In our case pulmonary toxicity resolved rapidly following the administration of corticosteroids. A possible deleterious synergy of the compounds involved in this case is discussed and the medical literature on NPE related to cancer therapy is shortly reviewed. We conclude that NPE should always be considered in patients with respiratory function deterioration while on therapy with the gemcitabine-docetaxel combination and G-CSF. Corticosteroids can provide maximum benefit if started early upon diagnosis coupled with withdrawal of the causative drugs.

Carboplatin plus paclitaxel in unknown primary carcinoma: a phase II Hellenic Cooperative Oncology Group Study.

PURPOSE: To evaluate the efficacy of the carboplatin/paclitaxel combination in patients with carcinoma of unknown primary site (CUP). PATIENTS AND METHODS: Seventy-seven consecutive CUP patients (45 women and 32 men; median age, 60 years) were treated with carboplatin at target area under the curve 6 mg/mL/min followed by paclitaxel 200 mg/m(2) as a 3-hour infusion and granulocyte colony-stimulating factor from days 5 to 12. Treatment courses were repeated every 3 weeks to a maximum of eight cycles. Forty-seven patients had adenocarcinomas, 27 had undifferentiated carcinomas, and three had squamous cell carcinomas. Thirty-three patients presented with liver, bone, or multiple organ metastases, 23 with predominantly nodal/pleural disease, and 19 (16 women) with peritoneal carcinomatosis. RESULTS: The overall response rate by intent-to-treat analysis was 38.7% (95% confidence interval, 27.5% to 49.9%). There were no differences in response between adenocarcinomas and undifferentiated carcinomas, but efficacy varied among clinical subsets. The response rates and median survival times in the three clinically defined subsets were 47.8% and 13 months, respectively, for patients with predominantly nodal/pleural disease, 68.4% and 15 months, respectively, in women with peritoneal carcinomatosis, and 15.1% and 10 months, respectively, in patients with visceral or disseminated metastases. Chemotherapy was well-tolerated. CONCLUSION: Carboplatin plus paclitaxel combination chemotherapy is effective in patients with predominantly nodal/pleural metastases of unknown primary carcinoma and in women with peritoneal carcinomatosis. However, in patients with liver, bone, or multiple organ involvement, the combination offers limited benefit. The investigation of novel treatment approaches is highly warranted for this group of patients.

Docetaxel and gemcitabine in anthracycline-resistant advanced breast cancer: a Hellenic Cooperative Oncology Group Phase II study.

A phase II study was conducted to evaluate the activity and toxicity profile of the combination of docetaxel and gemcitabine in anthracycline-resistant advanced breast cancer (ABC). Thirty-nine eligible patients with a median performance status of 1 (range, 0-2) were enrolled in the study. Treatment consisted of docetaxel 75 mg/m2 in a 1-hr infusion on day 1 preceded by gemcitabine 1000 mg/m2 over 30 min on days 1 and 8. One hundred eighty-one treatment cycles were administered, 113 (62.4%) of them at full dose. Relative dose intensity of gemcitabine and of docetaxel was 0.73 and 0.85, respectively. More common grade 3-4 toxicities included neutropenia (49%), anemia (10%), fatigue (10%), nausea/vomiting (8%), and alopecia (77%). Seven patients were hospitalized for febrile neutropenia. Granulocyte colony-stimulating factor (G-CSF) administration was required in 90% of patients. Overall, 14 patients (36%) responded, 3 (7.5%) of them completely. Median duration of response was 10.3 months (range, 4.6-17.5+). Median time to progression was 7 months (range, 0.2-17.5+) and median survival 12.7 months (range, 2-20.5+). In conclusion, the combination of docetaxel and gemcitabine, as used in the present study, has moderate activity in anthracycline-resistant ABC. Future studies should incorporate prophylactic administration of G-CSF to reduce the incidence of febrile neutropenia and maintain dose intensity.

Combination chemotherapy with paclitaxel plus carboplatin versus paclitaxel plus gemcitabine in inoperable non-small cell lung cancer: a phase III randomized study. Preliminary results. Hellenic Cooperative Oncology Group.

Gemcitabine plus paclitaxel and paclitaxel plus carboplatin are active and well tolerated in patients with advanced non-small cell lung cancer, showing similar rates of response and survival. The Hellenic Cooperative Oncology Group conducted a randomized phase III trial comparing gemcitabine plus paclitaxel with paclitaxel plus carboplatin. Patients were randomly assigned to two groups. Group A received paclitaxel 200 mg/m2 plus carboplatin (area under the curve = 6) on day I. Group B received paclitaxel in identical fashion to group A plus gemcitabine 1,000 mg/m2 on days I and 8 every 3 weeks. A minimum of two cycles and a maximum of six cycles was allowed. To date, 127 eligible patients (63 in group A and 64 in group B) have been randomized; the median follow-up time is 4.6 months. Preliminary results suggest that both combinations can be given in full doses and are well tolerated. Grade 3/4 neutropenia was mild but more prominent in group A (10% v 3%, respectively) while thrombocytopenia was not significant for either group. Moreover, severe neurotoxicity, hepatotoxicity, or cardiac toxicity has not been observed in the vast majority of patients in either group. Although patients in group B experienced higher response rates (37.5%) than those in group A (21.8%), the difference between the groups was not statistically significant. Definite conclusions about this study cannot be made until more data are available.

Combination chemotherapy with low doses of weekly Carboplatin and oral Etoposide in poor risk small cell lung cancer.

Sixty patients with poor prognostic features, either with extensive disease (ED) or limited disease (LD) small cell lung cancer (SCLC), were treated on an out-patient basis with Carboplatin 80 mg/m2 weekly for 3 weeks and oral Etoposide, at a dose of 100 mg, every other day for 21 days. The treatment was repeated every 5 weeks. Responding patients with LD were also treated with thoracic irradiation and those who achieved complete response (CR) received prophylactic cranial radio-therapy. The overall response rate (RR) was 32.1% with 8.9% CR. The responses were better for LD (RR 58.3%, CR 25%, partial response, PR 33.3%), than those for ED (RR 25%, CR 4.5%, PR 20.5%). The median time to progression (TTP) was 4.8 months and the median survival 5.5 months. These poor results could be attributed to the bad performance status and the presence of visceral and brain metastases in this group of patients. The results could also be due to the lower maximum concentration (Cmax) and higher T1/2 of Etoposide, as measured in the blood and urine probably due to the modified regimen used in our study and to the organ insufficiency in this selected group of patients. Although, toxicity was generally mild and manageable, two toxic deaths occurred. In conclusion, this regimen appears to have a lower efficacy in terms of response and survival than that obtained in other studies using Cisplatin or Carboplatin plus Etoposide in a similar way. Therapy with this regimen, though less toxic, may not be a reliable alternative in elderly patients with visceral metastases and ECOG performance status > or = 2.

Postoperative radiation and concomitant bolus fluorouracil with or without additional chemotherapy with fluorouracil and high-dose leucovorin in patients with high-risk rectal cancer: a randomized phase III study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: Randomized studies have shown that postoperative chemotherapy with or without radiation therapy (RT) improved local control and survival of patients with stages II or III rectal cancer. However, the optimal sequence of treatments and the optimal chemotherapeutic regimen have not been defined. Modulation of fluorouracil (FU) by leucovorin (LV) has yielded a highly significant difference in response rate from that of FU monotherapy, as suggested by an overview of randomized trials in patients with advanced colorectal cancer. However, this difference in response rate did not translate into a survival benefit. PURPOSE: To evaluate the impact on the disease-free survival (DFS) and overall survival (OS) of patients with stages II or III rectal cancer of postoperative RT and concomitant bolus FU administration alone or with additional chemotherapy using FU and high-dose LV. PATIENTS AND METHODS: From October 1989 until February 1997, 220 patients were randomized postoperatively to receive either one cycle of chemotherapy with FU (600 mg/m2/week x 6 followed by a two-week rest) and leucovorin (LV, 500 mg/m2/week x 6 as a two-hour infusion) followed by pelvic RT with concomitant FU (400 mg/m2) as a rapid intravenous injection during the first three and last three days of RT, and three more cycles of the same chemotherapy with FU and LV (standard, group A, 111 patients) or pelvic RT with concomitant FU only (experimental, group B, 109 patients). RESULTS: As of August 1998, after a median follow-up of 4.9 years, there was no significant difference in either three-year DFS (Group A, 70.3%; group B, 68.2%, P = 0.53) or OS (group A, 77%; group B, 73.3%. P = 0.75). Cox multivariate analysis revealed stage of disease, number of infiltrated nodes, tumor grade, presence of regional implants and perforation to be significant prognostic factors. The incidence of severe side effects was significantly higher in the patients in group A than in those in group B (32.4% vs. 4.6%, P < 0.0001). CONCLUSIONS: The incorporation of additional chemotherapy with FU and LV into postoperative concomitant RT and bolus infusion of FU does not offer a > or = 10% three-year survival benefit over that of concomitant RT and bolus infusion of FU, and significantly increases toxicity in patients with stages II or III rectal cancer.

Paclitaxel and gemcitabine in advanced non-nasopharyngeal head and neck cancer: a phase II study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: Paclitaxel as monotherapy or in combination with other drugs has demonstrated significant activity in patients with squamous cell carcinoma of the head and neck region (SCCHN). Preclinical studies have shown gemcitabine to be highly active in SCCHN cell lines. PURPOSE OF THE STUDY: To evaluate the activity and toxicity of the combination of paclitaxel by three-hour infusion and gemcitabine as first-line chemotherapy in patients with recurrent and/or metastatic head and neck cancer (HNC). PATIENTS AND METHODS: From September 1996 until May 1998, 44 patients with non-nasopharyngeal recurrent and/or metastatic HNC entered the study. There were 37 men and seven women with a median age of 61 years (range 35-79) and a median performance status of 1 (range 0-2). The location of the primary tumor in the majority of them was either the larynx or the oral cavity. Treatment consisted of six cycles of gemcitabine 1100 mg/m2 over 30 min on days 1 and 8 immediately followed on day 1 by paclitaxel 200 mg/m2 by three-hour infusion. The treatment was repeated every three weeks. RESULTS: Twenty-four (55%) patients completed all six cycles of treatment. A total of 205 cycles were administered, 165 (81%) of them at full dose. The median relative dose intensity (DI) of gemcitabine was 0.93 and of paclitaxel 0.95. Except for alopecia, which was universal, grade 3-4 toxicities included neutropenia (21%), thrombocytopenia (5%), anemia (5%), infection (5%), flu-like syndrome (5%) and peripheral neuropathy (2%). Five (11%) patients achieved complete and 13 (30%) partial responses, for an overall response rate of 41%. After a median follow-up of 13 months, the median time to progression was four months and median survival nine months. CONCLUSIONS: The combination of paclitaxel and gemcitabine is active and well tolerated in patients with recurrent and/or metastatic HNC-randomized studies comparing this combination with other regimens are warranted.

Weekly docetaxel in minimally pretreated cancer patients: a dose-escalation study focused on feasibility and cumulative toxicity of long-term administration.

BACKGROUND: Docetaxel is an agent with impressive clinical activity but a rather poor profile of toxicity when given every three weeks. Therefore, optimisation of its clinical use is highly warranted. This is a dose-escalation study of weekly docetaxel particularly focused on the feasibility of long-term administration and characterisation of cumulative toxicity. PATIENTS AND METHODS: Twenty-six patients (11 female/15 male, median age 56, range 23-73) were treated over the range of 25-50 mg/m2/week. Dose-limiting toxicity for this schedule was defined as any grade > 2 antiproliferative toxic effect resulting in a > 2-week delay for re-administration of the drug, or any grade > 2 organ-specific toxicity. Patients were monitored clinically and electrophysiologically for neurotoxicity. No prolonged corticosteroid co-medication or prophylactic haematopoietic growth factors were given. RESULTS: A median/mean number of 8.5/8.7 consecutive weekly courses were given per patient. The maximum tolerated dose that prevented on-schedule administration of the drug was 50 mg/m2. The main cumulative toxicities were a mild fluid retention and dacryorrhea which became evident as the number of treatment courses increased. Grade 2 alopecia and fatigue were observed only at 45 mg/m2 and higher. Activity was seen at all of the dose levels studied. CONCLUSIONS: Long-term weekly administration of docetaxel is feasible at doses up to 45 mg/m2/week with acceptable toxicity. Further clinical evaluation is justified at this schedule and 40 mg/m2/week of docetaxel is proposed for phase II studies as an active dose with minimal toxicity.

Weekly alternating non-cross-resistant chemotherapy for small cell lung cancer with a good prognosis: a study of the Hellenic Cooperative Oncology Group.

This trial was conducted by the Hellenic Cooperative Oncology Group to improve the responses and survival in small cell lung cancer with a good prognosis, using a weekly intensive chemotherapy with alternated non-cross-resistant myelosuppressive agents. Patients were classified into two groups; group A consisted of those who received the initial designed regimen (29 patients), and group B consisted of those who received the more intensified regimen that increased by 25% the doses of carboplatin, epirubicin, and ifosfamide, and by 33% the doses of etoposide given on days 1, 2, and 3 with prophylactic granulocyte colony-stimulating factor support. Chemotherapy in group A consisted of carboplatin 150 mg/m2 in 250 ml of 5% dextrose in water as an 1-hour infusion on day 1, etoposide 75 mg/m2 in 250 ml normal saline as an 1-hour infusion on days 1 and 2 alternating with epirubicin 30 mg/m2 intravenous push on day 8, and ifosfamide 2 g/m2 in 500 ml 5% dextrose in water as a 2-hour infusion with mesna protection on day 8. Responding patients with limited disease were also treated with thoracic irradiation. Those who achieved complete response received prophylactic cranial radiotherapy. In group A, the overall response rate was 79.3%, with a 27.6% complete response rate, a median time to progression of 5.71 months, and a median survival of 8.3 months. For patients with limited disease, the response rate was 75%, with a 40% complete response rate, a median time to progression of 5.87 months, and a median survival of 10.98 months. The respective numbers for extensive disease were 89% (only partial responses), 4.82 months, and 5.67 months. The toxicity was mild and manageable. There were no dose reductions or treatment delays. In view of the excellent tolerability and the rather low efficacy of the initial regimen, we decided to administer the more intensified one with granulocyte colony-stimulating factor support. In Group B, the overall response rate was 91.8%, with a 45.9% complete response rate, a median time to progression of 7.05 months, and a median survival of 10.16 months. For limited disease, the response rate was 93%, with a 52% complete response rate, a median time to progression of 7.05 months, and a median survival of 10.49 months. The respective numbers for extensive disease were 88% (25% complete response), 6.82 months, and 9.02 months. The toxicity of this more intensified regimen was more severe but acceptable. Myelosuppression was the main toxicity. However, grade 3-4 febrile neutropenia requiring hospitalization occurred only in 6% of patients. The relative dose intensity was 91%, probably the result of the prophylactic use of granulocyte colony-stimulating factor. The differences in response rate, time to progression, and survival were not statistically significant between the two groups. There were statistically significant differences in the response rate (p = 0.019) and survival rate (p = 0.001) between limited disease and extensive disease only in group A. In conclusion, this weekly, alternated regimen, specifically the intensified regimen, appears to be very active and well tolerated in patient who have small cell lung cancer with a good prognosis. However, despite the high efficacy, this study failed to show any survival advantage as compared with that obtained with the standard treatment for small cell lung cancer.
