High-dose multimodality therapy with autologous stem-cell support for stage IIIB breast carcinoma

PURPOSE: Women with locally unresectable and inflammatory breast carcinoma (IBC) have an approximately 30% 5-year disease-free survival (DFS) rate with conventional multimodality therapy. A short but dose-intensive multimodality phase II trial was designed in an attempt to improve outcome in stage IIIB disease. Mastectomy was performed after high-dose therapy to evaluate pathologic response to treatment. METHODS: Women with newly diagnosed disease received four 2-week cycles of doxorubicin 90 mg/m2 with granulocyte colony-stimulating factor (G-CSF), followed by cyclophosphamide 6,000 mg/m2, thiotepa 500 mg/m2, and carboplatin 800 mg/m2 (CTCb) with marrow and peripheral-blood progenitor cell (PBPC) support. Local therapy consisted of mastectomy and radiotherapy. Tamoxifen (5 years) was begun if the patient was estrogen receptor-positive (ER+). RESULTS: Fifty women (46 stage IIIB [91% IBC], four stage IIIA) entered the study and 47 are assessable. Ten had mastectomy before any systemic therapy (seven with pathologic IBC, three with residual tumor after mastectomy). Eighty percent received full-dose doxorubicin with 60% on schedule. Clinical response rates to induction were 15% complete response (CR), 5% very good partial response (VGPR), 59% partial response (PR), and 21% minor response (MR)/stable disease (SD). Mastectomy after CTCb in 37 patients showed a 14% pathologic CR rate, 29% microscopic foci in breast and/or axilla, and 57% gross tumor. Fifteen (32%) patients have relapsed (median, 17 months post-CTCb). The 30-month DFS is estimated at 64%. For those in pathologic CR, with microscopic, or with gross disease remaining after CTCb, the 30-month DFS is estimated at 100%, 70%, and 38%, respectively. Those with zero, one to three, or > or = four positive nodes at axillary dissection had a median DFS of 31, 18, and 13 months, respectively. CONCLUSION: This short but dose-intensive multimodality approach for stage IIIB breast carcinoma is feasible with encouraging results to date.     

Treatment of patients with transitional-cell carcinoma of the urothelial tract with ifosfamide, paclitaxel, and cisplatin: a phase II trial

PURPOSE: A phase II trial of ifosfamide, paclitaxel, and cisplatin (ITP) was conducted in previously untreated patients with advanced transitional-cell carcinoma (TCC) to assess its efficacy and toxicity. PATIENTS AND METHODS: Thirty patients with metastatic or unresectable TCC were treated with ifosfamide 1.5 g/m2/d for 3 days with paclitaxel 200 mg/m2 over 3 hours and cisplatin 70 mg/m2 on day 1 of each 28-day treatment cycle. Therapy was continued for a maximum of six cycles. Prophylactic hematopoietic growth factor (recombinant human granulocyte colony-stimulating factor [rhG-CSF]) was given on days 6 to 17 of each cycle. RESULTS: Twenty-three of 29 assessable patients (79%; 95% confidence interval [CI], 60% to 92%) demonstrated a major response (six complete [CR] and 17 partial [PR]) with response durations that ranged from 5 to 24+ months. Five patients with T4 bladder primary tumors had a major response, two with pathologic CR. At a median follow-up duration of 17.9 months, nine (31%) patients remain disease-free (range, 10+ to 24+). Hematologic toxicity included anemia, thrombocytopenia, and neutropenia; febrile neutropenia was observed in 17% of patients and 4% of cycles. No grade 4 nonhematologic toxicity was observed. Grade 3 nonhematologic toxicity included alopecia, allergy (3%), renal insufficiency (13%), and neuropathy (10%). Dose reductions or drug omissions were necessary for adverse events in seven (23%) patients. CONCLUSION: ITP is an active, well-tolerated regimen in previously untreated patients with TCC of the urothelial tract. Further study of this regimen in patients with both TCC and non-transitional-cell urothelial tumors is ongoing.     

Characterization and cloning of a 37.6-kb plasmid carried by Legionella pneumophila recovered from patients and hospital water over a 12-year period

High-dose chemotherapy is associated with a high complete response rate and possibly some survival advantage in patients with metastatic breast cancer. We designed a clinical trial consisting of a two-step high-dose chemotherapy regimen followed by posttransplantation doxorubicin as the first chemotherapy treatment for metastatic disease. Twenty-one patients with metastatic breast cancer and no previous chemotherapy for metastatic disease were treated with high-dose cyclophosphamide (Cy; 5000 mg/m2), followed by granulocyte colony-stimulating factor. Peripheral blood stem cells were collected. Subsequently, patients received Cy (6000 mg/m2), thiotepa (500 mg/m2), and carboplatin (800 mg/m2) (CTCb) with hematopoietic rescue. Upon recovery of hematopoietic and gastrointestinal toxicity, three cycles of doxorubicin (Dox; 60 mg/m2) were delivered. After Cy, nine patients (45%) developed neutropenic fevers. There were no episodes of bacteremia. Patients received CTCb 37 days after starting Cy and had a hospital stay of 19 days. After CTCb, the median number of days to an absolute neutrophil count >5 x 10(9)/liter was 8, and the median number of days to a platelet count >20 x 10(9)/liter was 9. Neutropenic fevers occurred in 12 patients. There were no hemorrhagic complications. Fifty-five of the 63 planned courses of Dox were delivered. The median time from peripheral blood stem cell infusion to the first Dox cycle was 38 days. The median time to the second Dox cycle was 28 days, and to the last cycle was 30 days. Three episodes of neutropenic fevers were observed. Two patients developed herpes zoster. This regimen is feasible, with acceptable toxicity.     

Paclitaxel plus high-dose cyclophosphamide with G-CSF support in patients with relapsed and refractory aggressive non-Hodgkin's lymphoma

Based on the single-agent activity of both paclitaxel and cyclophosphamide in the treatment of non-Hodgkin's lymphoma (NHL), we conducted a phase II study to evaluate the efficacy of the combination of the two drugs in patients with refractory and relapsed aggressive NHL. All patients received 900 mg/m2 bolus of cyclophosphamide intravenously daily for 3 consecutive days with a concurrent infusion of 150 mg/m2 of paclitaxel over 72 h (50 mg/m2/d). 24 h after the completion of chemotherapy, patients received subcutaneous injections of 5 microg/kg of granulocyte-colony stimulating factor (G-CSF) daily until white cell count recovery. Treatment was repeated every 3 weeks. Patients who had at least a partial response (PR) after two courses continued to receive a maximum of four courses. Patients with responding disease were allowed to undergo high-dose chemotherapy followed by stem-cell/bone marrow transplantation if they were eligible. Of the 77 patients who were eligible for the study, 74 (96%) were evaluable for toxicity and treatment response. The overall response rate was 45% (95% CI 33-57%). Patients who received treatment after their disease relapsed from a complete response (CR) had an 81% response rate (38% CRs), whereas those with primary refractory disease had a 22% response rate. Toxicities of > grade 2 included alopecia (100%) and stomatitis (25%). Neutropenic fever of grade > 2 occurred after 18% of the courses, and platelet count of < or = 20 x 10(9)/l developed after 20% of the courses. Thus, the combination of paclitaxel plus high-dose cyclophosphamide is an effective new regimen in the treatment of refractory and relapsed NHL.     

High-dose chemotherapy with carboplatin, etoposide and cyclophosphamide followed by a haematopoietic stem cell rescue in patients with high-risk retinoblastoma: a SFOP and SFGM study

This study investigates the role of high-dose chemotherapy with haematopoietic stem cell rescue as consolidation treatment in high-risk retinoblastoma (extraocular disease at diagnosis or relapse or invasion of cut end of optic nerve). 25 patients received high-dose chemotherapy including carboplatin (250 mg/m2/day from day 1 to day 5 for the 6 first patients and 350 mg/m2/day from day 1 to day 5 for the other patients), etoposide (350 mg/m2/day from day 1 to day 5) and cyclophosphamide (1.6 g/m2/day from day 2 to day 5) (CARBOPEC) followed by autologous haematopoietic stem cell rescue. 19 patients received this drug combination for chemosensitive extraocular relapse. The other 6 patients with histological high-risk factors were given this treatment as consolidation after enucleation and conventional chemotherapy. The three year disease-free survival was 67.1%. In 7 of the 9 relapsing patients, the first site of relapse was the central nervous system. All patients with central nervous system disease died except one. The main toxicity was haematological and digestive (mucositis and diarrhoea). 2 of the 13 evaluable patients had grade III and IV ototoxicity. One patient experienced an acute grade I reversible cardiotoxicity. The CARBOPEC regimen seems to be a promising therapeutic strategy in patients with high-risk retinoblastoma, especially those with bone and/or bone marrow involvement. This treatment did not improve the outcome of patients with central nervous system disease.     

The expression of HLA, Epstein-Barr virus nuclear antigen and the infiltration of T lymphocyte subsets in nasopharyngeal biopsy tissues

In this study, 79 patients with locally advanced head and neck cancer were treated with induction chemotherapy. Cisplatin, 25 mg/m2, and 5-fluorouracil (5-FU), 1000 mg/m2, were employed, both of them in 24-hour continuous infusion over 96 hours, four cycles. The patients later underwent surgery and/or radiation therapy. The response to chemotherapy was 49%: of the complete responses (CR), 56% were histological; 29% were partial responses (PR). With the administration of the fourth cycle, CR increased from 30% to 49%. Once the complete treatment had been finished, 75% of CR and 5% PR were achieved. With a maximum follow-up period of 44 months, overall survival stands at 50%.     

Very high-dose chemotherapy with autologous peripheral stem cell support in advanced ovarian cancer

20 patients with stage III-IV ovarian cancer were submitted to induction chemotherapy (ICT) (40 mg/m2 cisplatin, days 1-4; 1.5 g/m2 cyclophosphamide, day 4; every 4 weeks for 2 cycles) followed by intensified CT (100 mg/m2 cisplatin, day 1; 650 mg/m2 etoposide, day 2; 1.8 g/m2 carboplatin by 24 h infusion, day 3). Haematological support consisted of autologous peripheral stem cells (APSC) and bone marrow (ABM) transplant (T) in 16 and 4 patients, respectively. All patients were evaluable for toxicity and 19 for pathological response (PR), one patient dying of systemic mycosis after ABMT. Severe (grade 3-4) non-haematological toxic effects were gastrointestinal (100%), neurological (10%) and hepatic (10%). PR was observed in 84% of patients (complete response 37%, partial response with microscopic residual disease 26%, partial response with macroscopic residual disease 21%). Five year overall survival was 60% and progression-free survival was 51% with 9 patients still disease-free (DFS). APSCT significantly reduced the duration of aplasia compared with ABMT, and toxicity was acceptable in those patients undergoing APSCT. The prolonged DFS in patients showing PCR suggests that this new approach may have a therapeutic impact.     

Induction therapy with an immunomodulatory CD2 antibody does not inhibit allograft vasculopathy after rat heart transplantation

Peripheral neuropathy (PN) is the main side effect with cycles of paclitaxel at standard doses (175 mg/m2 for 21 days). Administration of a single high-dose paclitaxel (HDP) is a novel approach for the treatment of cancer. We have prospectively measured neurotoxicity induced by HDP during a phase I trial. Nineteen patients were treated with escalating doses of paclitaxel by 24-hour infusion. In our study, PN induced by HDP was moderate, reversible, and not dose limiting. Severe PN was seen in patients who had received previous neurotoxic chemotherapy, and caution on the administration of HDP in this setting is warranted.     

Final report of a phase II study of chemotherapy with bleomycin, epirubicin, and cisplatin for locally advanced and metastatic/recurrent undifferentiated carcinoma of the nasopharyngeal type

PURPOSE: This article presents an assessment of the combination of bleomycin, epirubicin, and cisplatin as induction chemotherapy before radiotherapy in the treatment of undifferentiated carcinoma of the nasopharyngeal type in patients with recurrent/metastatic disease (group A), and in previously untreated patients with locoregionally advanced disease (UICC-AJCC 87, N2-3, M0) (group B) in terms of toxicity, antitumoral activity, and therapeutic efficacy. PATIENTS AND METHODS: From January 1987 to September 1990, 111 consecutive patients with histologically proven UCNT were treated with six cycles of intravenous cisplatin (100 mg/m2 day 1) epirubicin (80 mg/m2 day 1), and bleomycin (15 mg bolus day 1), followed by 16 mg/m2/day continuous infusion for 5 days, repeated every 21 days for three cycles. Three further cycles without bleomycin were given to 44 patients in group A. In group B (67 patients), only three cycles of the same protocol were given, with a slightly lower dose of epirubicin (70 mg/m2), followed by conventional radiotherapy (70 Gy/7 weeks). RESULTS: Of 44 patients entered in group A, 38 were evaluable for response. We observed 9 (20%) complete responses and 11 (25%) partial responses, for a 45% overall response rate. In 12 patients not previously given chemotherapy, there were 4 complete responses, compared to 5 complete responses in 32 patients previously treated with chemotherapy. Four patients are alive with no evidence of disease after 53+, 60+, 61+, and 72+ months. In group B the overall response rate to chemotherapy was 98% with 42 complete (62%) and 24 partial responses (36%). Three months after the end of radiotherapy, the overall complete response rate was 94% (63 patients). After a median follow-up time of 77 months (range, 53-94), the 4-year overall survival and disease-free survival rates for this group are 66% and 60%, respectively. The median disease-free survival has not been reached at 90 months. CONCLUSION: The results of the BEC combination trial are very encouraging in metastatic and recurrrent UCNT, with durable remissions in this poor-prognosis population. The results in patients with locally advanced disease have motivated prospective phase III testing of the neoadjuvant chemotherapy approach to evaluate its impact on locoregionally advanced disease (> or =N2MO UICC-AJCC 87).     

Scaling of movement velocity: a measure of neuromotor retardation in individuals with psychopathology

The combination of ifosfamide, carboplatin and etoposide (modified ICE), was evaluated for its toxicity and activity in relapsed or refractory aggressive non-Hodgkin's lymphoma. Twenty patients, 14-69 years of age, with relapsed (19 cases) or refractory (one case) aggressive non-Hodgkin's lymphoma were treated with modified ICE therapy, consisting of ifosfamide 6 g/m2 (1.2 g/m2 day 1-5), carboplatin 400 mg/m2 (day 1) and etoposide 500 mg/m2 (100 mg/m2 day 1-5). The regimen was repeated at approximately 28-day intervals. All patients had undergone a doxorubicin-containing regimen before modified ICE therapy. Median total dose of previously received doxorubicin was 406 mg/m2 (range: 200-825 mg/m2). The median interval from diagnosis to modified ICE therapy was 9.4 months (range: 3.6-121 months). Two patients achieved CR and five achieved PR out of 16 patients with measurable lesions (response rate 43.8%; 95% confidence interval 19.0-68.6%). Median overall survival was 227 days (range: 41-552 days) from the start of modified ICE therapy. Myelosuppression was the most serious toxicity, namely 16 patients (80%) and 11 patients (55%) showed grade 4 neutropenia and grade 4 thrombocytopenia after the first course, respectively. Modified ICE therapy might be an active regimen with acceptable toxicity as a salvage chemotherapy in aggressive non-Hodgkin's lymphoma.     

Phase II-trial of double-consolidation following intensive induction treatment for improvement of survival in elderly patients with acute myeloid leukemia

Thirty-two consecutive, unselected acute myeloid leukemia (AML) patients (pts) of all FAB-subtypes with a median age of 68 years were treated with intensive induction chemotherapy consisting of one or two cycles of daunorubicin 30 mg/m2 day 1-3 and Ara C 100 mg/m2 as continuous infusion day 1-7. The overall CR rate was 50%, 14/24 (58%) in de novo AML, and 2/8 (25%) with preceding MDS. One patient achieved a PR of 21 months duration, 3 pts died within 7 days of the induction treatment (ED), 6 died during hypoplasia (HD), and 6 remained refractory to 2 cycles of induction. Four pts died after achieving CR. Of the remaining 12 responders, 11 pts received 2 cycles of consolidation consisting of daunorubicin 30 mg/m2 day 1, and Ara C 100 mg/m2 continuous IV infusion day 1-7. No deaths were observed during consolidation. DFS and survival of responders were 7 and 13 months respectively, survival of all pts, responders and non-responders, was 7 months. Large cooperative trials are necessary to identify those elderly pts who may benefit from intensified consolidation treatment.     

Intensive sequential chemotherapy with repeated blood stem-cell support for untreated poor-prognosis non-Hodgkin's lymphoma

PURPOSE: To demonstrate the feasibility and efficacy of six ambulatory high-dose sequential chemotherapy courses that include three intensified cycles supported by stem-cell infusion in high-risk and high-intermediate-risk untreated non-Hodgkin's lymphoma (NHL) patients. PATIENTS AND METHODS: A pilot nonrandomized study included 20 untreated patients aged less than 60 years with aggressive histologically identified NHL and two or three adverse-prognosis criteria (International Index). Patients received an ambulatory regimen with high-dose chemotherapy supported by granulocyte colony-stimulating factor (G-CSF) and repeated peripheral-blood stem-cell (PBSC) infusion. The median age was 39 years (range, 20 to 59), with 13 men and seven women. Chemotherapy consisted of one cycle every 21 days for a total of six cycles. The first three cycles (A1, A2, and A3) consisted of cyclophosphamide (Cy) 3,000 mg/m2, doxorubicin (Doxo) 75 mg/m2, and vincristine 2 mg (plus corticosteroids). The last three cycles (B4, B5, and B6) consisted of the same drug combination plus etoposide 300 mg/m2 and cisplatin 100 mg/m2. For an expected duration of 18 weeks, the projected dose-intensity was 25 mg/m2/wk for Doxo and 1,000 mg/m2/wk for Cy. G-CSF 300 micrograms was administered from day 6 following each cycle until neutrophil reconstitution. Two aphereses were performed at approximately day 13 after each A cycle, and PBSCs were injected at day 4 of each B cycle. Radiotherapy on tumor masses > or = 5 cm was scheduled after completion of the last cycle. RESULTS: The median duration of grade 4 neutropenia was 1 day (range, 0 to 7) for each A cycle and 4 days (range, 1 to 10) for each B cycle (P = .02). The median duration of grade 4 thrombopenia was 0 days (range, 0 to 8) for each A cycle and 6 days (range, 1 to 21) for each B cycle (P < .001). Hospitalization for febrile neutropenia was required for 18% and 44% of patients during cycles A and B, respectively (P < .01). Only three patients did not complete the protocol: one due to emergency surgery after cycle B4, one who died after cycle B5 from interstitial pneumonia, and one with delayed hematologic reconstitution after cycle B4. Chemotherapy delivery was optimal (median actual relative dose-intensity, 97%; range, 66 to 100). The median total dose administered over 18 weeks was 18,000 mg Cy (range, 12,000 to 18,000), 450 mg Doxo (range, 300 to 450), 900 mg etoposide (range, 300 to 900), and 300 mg cisplatin (range, 100 to 300). Evaluation of response after six courses showed 13 complete remissions ([CRs] 65%), four partial remissions (PRs), two nonresponses (NRs), and one toxic death. With a median follow-up period of 25 months (range, 16 to 43), 15 patients are alive, with 12 in continuous first CR; five patients relapsed (four of four PRs and one of 13 CRs). Two-year survival and failure-free survival (FFS) rates are 73% and 56%, respectively. The disease-free survival (DFS) rate for the CRs is 86%. CONCLUSION: PBSC support contributes to the feasibility of first-line, very-high-dose, ambulatory chemotherapy delivery in poor-risk NHL and is associated with a high rate of remission and FFS.     

Chemotherapy immediately following autologous stem-cell transplantation in patients with advanced breast cancer

Most patients relapse after high-dose chemotherapy (HDCT) with autologous stem-cell transplantation (ASCT) for metastatic breast cancer. Further chemotherapy immediately after hematopoietic recovery from ASCT is not given for fear of irreversibly damaging the newly engrafted stem cells. In a pilot chemoprotection trial, autologous CD34+ cells from patients with metastatic breast cancer were exposed to a replication-incompetent retroviral vector carrying MDR-1 cDNA and then reinfused after HDCT. Immediately on recovery, patients received multiple courses of escalating dose paclitaxel. All of the 10 patients tolerated reinfusion of modified cells without any toxicity and had myeloid engraftment within 12 days (range, 11-14). The bone marrow cells of three patients contained vector MDR-1-positive cells only at the time of the first course of posttransplant paclitaxel, indicating that the MDR-1 vector-modified cells had only short-term engrafting potential. A total of 83 courses of paclitaxel were administered starting at a median of 30 (range, 21-32) days from ASCT. The median dose of paclitaxel was 225 mg/m2 and the median interval between paclitaxel cycles of therapy was 21 (range, 20-41) days. Five of the six CR patients were able to receive all of the 12 courses of paclitaxel. Three patients who had achieved less than a complete response to the HDCT (2 patients) and partial response (1 patient) were converted to complete clinical responses during the 12 cycles of paclitaxel. No delayed toxicity or bone marrow failure was noted in these patients with a median follow-up of 2 years from ASCT. This is the first study of chemotherapy immediately after transplantation with autologous CD34+ cells. These data indicate that paclitaxel can be safely administered immediately after ASCT without any delayed toxicities. Paclitaxel given immediately after ASCT can further improve the response to pretransplant chemotherapy in patients with advanced breast cancer.     

Haemorrhagic hydrops of the gallbladder

Primary carcinoma of the fallopian tube is uncommon; optimal primary treatment is still not well defined, and little information is available about the efficacy of cisplatin-based combination chemotherapy. Thirty-eight patients with fallopian tube carcinoma were treated with cyclophosphamide (500 mg/m2), Adriamycin (50 mg/m2), and cisplatin (50 mg/m2) (CAP). Thirty-two patients received the combination chemotherapy as first-line treatment after cytoreductive surgery, whereas six subjects were treated for recurrent disease. The patients received a median of six cycles of therapy (range, four to nine). At the initiation of chemotherapy, 24 patients had measurable lesions. In this group of patients, 15 had a clinical complete response (CR), four had a partial response (PR), three had stable disease (SD), and two had progressive disease (PD) after chemotherapy. The overall clinical response rate (CR + PR) was 80%. Ten of the 14 CR patients who were submitted to second-look operation (SLO) were found free of disease, in pathologic complete response (pCR). Three pCR patients relapsed, and two of them died despite second-line treatment. Nine patients achieving PR, SD, and PD after first-line chemotherapy were further treated (five with chemotherapy, two with radiotherapy, two with progesteron), but none responded to second-line treatment and all died (median survival, 9 months). Fourteen patients without gross residual disease after cytoreductive surgery had no measurable lesions and were not evaluable for response. Seven of them had negative SLO and remain disease free. Three patients (two stage III and one stage II) who refused SLO relapsed 14, 16, and 26 months after completion of chemotherapy. The median survival for the entire group was 38 months, and the 5-year survival rate was 35%. The toxicity of the regimen was moderate. The CAP regimen appears to be active in primary fallopian tube carcinoma and yields response rates comparable to those reported for epithelial ovarian cancer.     

Dipyridamole modulated Tc-99m sestamibi lung SPECT in small cell lung cancer

PURPOSE: In this study, the authors wanted to determine whether dipyridamole-modulated MIBI (dipyridamole-MIBI) could enhance the prediction of the response to chemotherapy in patients with small cell lung cancer. METHODS: Twenty-seven patients with biopsy-proved small cell lung cancer (25 men, 2 women; mean age, 61 +/- 7 years) underwent dipyridamole-MIBI SPECT 3 to 7 days before starting chemotherapy (80 mg/m2 etoposide and 80 mg/m2 cisplatin every 3 or 4 weeks for at least two cycles). Tomographic images before and after dipyridamole (0.84 mg/kg) were acquired 1 hour after injection of 370 (10 mCi) and 1,110 (30 mCi) MBq MIBI, respectively. The response to chemotherapy was grouped as specified as complete response (CR), partial (PR), no change (NC), or progressive disease (PD), according to the change in tumor size on chest roentgenography and CT. Patients showing CR and PR were classified as responders, and those who showed NC and PD were considered nonresponders. RESULTS: Among the 27 patients, 22 were responders (3 CR, 19 PR) and 5 were nonresponders (3 NC, 2 PD). The tumor-to-normal lung ratio (T:NL) of responders was significantly higher than that of nonresponders. The diagnostic accuracy of the T:NL ratio to differentiate responders and nonresponders was 33.3%, with a cutoff value of 2.5, which was significantly improved to 77.8% when an increased T:NL ratio after dipyridamole was assigned to a nonresponder. Furthermore, all patients with CR showed diminished T:NL ratios after dipyridamole, and all patients with NR showed an increased T:NL ratio after dipyridamole. CONCLUSION: Dipyridamole-MIBI SPECT could enhance the prediction of response to chemotherapy in patients with small cell lung cancer.     

Development of a biochemotherapy regimen with concurrent administration of cisplatin, vinblastine, dacarbazine, interferon alfa, and interleukin-2 for patients with metastatic melanoma

PURPOSE: To evaluate the antitumor activity and toxicity of concurrent biochemotherapy that uses cisplatin, vinblastine, and docarbazine (DTIC) (CVD) in combination with interferon alfa-2a (IFN-alpha) and interleukin-2 (IL-2) in patients with metastatic melanoma. PATIENTS AND METHODS: Between October 1992 and October 1993, 53 patients with a documented diagnosis of metastatic melanoma with measurable lesions and an Eastern Oncology Cooperative Group (ECOG) performance status of 2 or less were enrolled onto this study. Patients were required to have no clinically significant cardiac dysfunction and to be free from symptomatic brain metastases. The treatment consisted of cisplatin 20 mg/m2 daily for 4 days; vinblastine 1.6 mg/m2 daily for 4 days; and DTIC 800 mg/m2 intravenously (i.v.) day 1 with IL-2 9 x 10(6) IU/m2 i.v. by continuous infusion daily for 4 days and IFN-alpha 5 x 10(6) U/m2 subcutaneously daily for 5 days, repeated at 21-day intervals. Response was assessed after two cycles and patients who responded were continued on treatment for a total of six cycles. RESULTS: Among 53 assessable patients, 11 patients (21%) achieved a complete response (CR) and 23 patients (43%) achieved a partial response (PR), for an overall objective response rate of 64%. The median time to disease progression for all patients was 5 months. The median survival of all patients entered onto the trial was 11.8 months. Among the 11 patients who achieved a CR, five patients (9%) have remained in continuous CR for 50+ to 61+ months. The toxicity of biochemotherapy consisted of severe myelosuppression, significant nausea and vomiting, and moderately severe hypotension that required inpatient hospital care for each 5-day cycle of treatment. There were no treatment-related deaths. CONCLUSION: Concurrent biochemotherapy for patients with advanced melanoma is capable of producing high CR and overall response rates and resulted in durable complete remissions in a small fraction of patients. Toxicity, although severe, was manageable in a routine inpatient hospital environment.     

Paclitaxel with mitoxantrone, fluorouracil, and high-dose leucovorin in the treatment of metastatic breast cancer: a phase II trial

PURPOSE: Paclitaxel is a highly active single agent in the treatment of breast cancer. However, its optimal incorporation into combination regimens awaits definition. In this phase II study, we added paclitaxel, administered by 1-hour infusion, to a previously described combination regimen that included mitoxantrone, fluorouracil (5-FU), and high-dose leucovorin (NFL). PATIENTS AND METHODS: Forty-six patients with metastatic breast cancer received the following regimen as first- or second-line treatment: paclitaxel 135 mg/m2 by 1-hour intravenous (i.v.) infusion on day 1, mitoxantrone 10 mg/m2 by i.v. bolus on day 1, 5-FU 350 mg2/m by i.v. bolus on days 1, 2, and 3, and leucovorin 300 mg i.v. over 30 to 60 minutes immediately preceding 5-FU on days 1, 2, and 3. Courses were administered at 3-week intervals for a total of eight courses in responding patients. RESULTS: Twenty-three of 45 assessable patients (51%) had major responses. Previous chemotherapy, and in particular previous treatment with doxorubicin, did not affect response rate. The median response duration was 7.5 months. Myelosuppression was moderately severe, with 76% of courses resulting in grade 3 or 4 leukopenia. Hospitalization for treatment of fever during neutropenia was required in 13% of courses, and two patients died as a result of sepsis. Two patients developed severe congestive heart failure after a large cumulative anthracycline dose. CONCLUSION: This combination regimen was active as first- or second-line therapy for metastatic breast cancer, although its activity compared with other combination regimens or with paclitaxel alone is unclear. Myelosuppression was more severe than anticipated based on previous results with the NFL regimen or with paclitaxel administered at this dose and schedule as a single agent. The infrequent development of cardiotoxicity in these patients suggests that the paclitaxel/mitoxantrone combination may not share the problems previously reported with the paclitaxel/doxorubicin combination.     

A phase I-II study of paclitaxel, ifosfamide, and vinorelbine with filgrastim (rhG-CSF) support in advanced non-small-cell lung cancer

PURPOSE: We designed a phase I-II trial of three active agents, paclitaxel, ifosfamide, and vinorelbine, in advanced non-small-cell lung cancer (NSCLC) to: 1) define the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of paclitaxel with filgrastim (G-CSF) support; and 2) determine the overall response rate and median survival of patients treated on this regimen. PATIENTS AND METHODS: We treated cohorts of patients with stage IIIB or IV NSCLC with ifosfamide 1.2-1.6 g/m2/day x 3 and vinorelbine 20-25 mg/m2/day x 3 and escalating doses of paclitaxel at 100-175 mg/m2 on day 2 with G-CSF support on a 21-day cycle. One prior experimental single-agent chemotherapy regimen was allowed. RESULTS: Fifty-six patients, were enrolled on this trial: 27 on the phase I portion of the study and an additional 29 at the recommended phase II dose (RPTD). Thirteen patients had received prior chemotherapy. Paclitaxel doses of 175 mg/m2 and 150 mg/m2 produced dose-limiting myelosuppression, and the RPTD was determined to be paclitaxel 135 mg/m2 with ifosfamide 1.2 g/m2/day on days 1-3 and vinorelbine 20 mg/m2/ day on days 1-3 with G-CSF support. The overall response rate was 18%, with a median survival of 6.1 months. Six of 35 patients (17%) treated at the RPTD achieved a partial response to therapy. Grade IV neutropenia was observed in 19 of 35 patients at this dose, with eight patients suffering febrile neutropenia. CONCLUSIONS: This non-cisplatin-containing three-drug regimen has substantial toxicity and low activity in advanced NSCLC, and does not seem to improve on prior regimens. It is unclear whether the lack of efficacy relates to an antagonistic reaction between the specific drugs, administration schedule, or to subtherapeutic doses of the individual agents.     

Phase II trial of paclitaxel and carboplatin in the treatment of advanced urothelial carcinoma

PURPOSE: Both paclitaxel and carboplatin have single-agent activity against carcinoma of the urothelium. We evaluated the combination of paclitaxel and carboplatin in the treatment of advanced cancers of the urothelium. PATIENTS AND METHODS: Patients with cancers of the urothelium who had no prior chemotherapy (prior adjuvant chemotherapy > 6 months allowed) were eligible for treatment. Eligibility requirements were performance status of 2 or less, creatinine level less than 2.0 mg/dL, granulocyte count (AGC) 1,500/microL or greater, platelet count 100,000/microL or greater, and total bilirubin level less than 1.5 mg/dL. Paclitaxel 200 mg/m2 followed by carboplatin (area under the curve [AUC] 5, Calvert formula) were administered every 21 days. Patients were evaluated for toxicity weekly and assessed for response every 6 weeks. RESULTS: Thirty-six patients were entered onto the study and 35 patients were assessable for response. A total of 184 cycles were administered (median, six cycles per patient). Nine patients required one dose reduction, and seven patients required two dose reductions for a nadir AGC less than 500/microL, with only one episode of febrile neutropenia and sepsis. Myalgias and arthralgias of grades 1 to 2 occurred in 16 patients and usually lasted 2 to 3 days after treatment. There were no treatment delays because of toxicity. There were 18 responses; seven complete responses (CRs) and 11 partial responses (PRs) (response rate 51.5%; 95% confidence interval, 35 to 68). Median response durations for CR and PR were 6 and 4 months, respectively. Overall median survival was 9.5 months. CONCLUSION: The combination of paclitaxel and carboplatin is an active and well-tolerated regimen for the treatment of advanced urothelial carcinoma. Because of the modest toxicity of this combination, paclitaxel and carboplatin should be considered for addition to other agents with activity in urothelial carcinomas.     

Deletion of chromosome 22q11 and pseudohypoparathyroidism

Multiple myeloma with IgG kappa monoclonal gammopathy and oliguric renal failure requiring hemodialysis was diagnosed in a 49-year-old man. Conventional therapy with VAD (vincristin, adriamycin, dexamethasone) failed to induce a complete response (CR) but this was subsequently obtained following two cycles of high-dose intravenous melphalan (70 mg/m2). A relapse occurred 8 months after CR which was treated by intensive myeloablative therapy combining total body irradiation (6 Gy over 2 days) and high-dose intravenous melphalan (140 mg/m2) followed by supportive PBSC transplantation. Hemodialysis was performed every other day during the myeloablative therapy and subsequent aplasia. Fluid subtraction allowed 1500 Cal/day intravenous alimentation and the only adverse event observed was a severe mucositis. A second CR was obtained which lasted 14 months. This observation indicates that multiple myeloma patients with end-stage renal failure can receive intensive myeloablative therapy without major toxicity.
