Effect of recombinant human granulocyte-macrophage colony-stimulating factor in patients with Hodgkin's disease: a phase I/II study.
Authors: Hovgaard D J , Nissen N I 
Published: February 2017

PURPOSE As bone marrow toxicity is the major limitation of the optimal administration of chemotherapy, we investigated whether recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) could prevent myelotoxicity or accelerate hematopoietic recovery after mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy. PATIENTS AND METHODS Twenty-four previously untreated patients with Hodgkin's disease were included in a phase I/II study in which standard MOPP chemotherapy was followed by 5 days of GM-CSF at every other cycle. Patients were entered sequentially to receive one of four dosc levels (2, 4, 8, and 16 micrograms/kg of glycoprotein; 1.4, 2.8, 5.5, and 11.0 micrograms/kg of protein) and were randomly allocated to either 24-hour continuous intravenous (IV) infusion or twice daily subcutaneous (SC) injection of rhGM-CSF. RESULTS WBC counts (mainly neutrophils, eosinophils, and monocytes) were significantly higher in cycles with rhGM-CSF than in cycles with MOPP alone. The total number of days of leukopenia (WBC count less than or equal to 2.0 x 10(9)/L) and neutropenia (absolute neutrophil count [ANC] less than or equal to 1.0 x 10(9)/L) was reduced in cycles with rhGM-CSF from 6.3 to 0.8 days and from 5.4 to 1.0 days, respectively. All dose levels of rhGM-CSF were effective in increasing the ANC, but only at the dose levels of 8 and 16 micrograms/kg did this significantly affect the scheduling of chemotherapy. Mild and reversible adverse reactions included low-grade fever, chest/bone pain, myalgias, erythemia, headache, fatigue, and periorbital edema. CONCLUSIONS rhGM-CSF can be administered safely to patients with Hodgkin's disease and results in improved hematologic recovery after MOPP. Full-dose chemotherapy can be administered on time, resulting in an increase in the overall tolerated dose of myelosuppressive drugs when compared with historical controls. SC administration proved to be at least as effective as continuous IV infusion and should be preferred.

PURPOSE The trial was undertaken to study the effect of administering granulocyte-macrophage colony-stimulating factor (GM-CSF) with and without peripheral-blood progenitor cells (PBPC) on the hematologic and nonhematologic toxicity observed with multiple cycles of high-dose carboplatin chemotherapy. PATIENTS AND METHODS Eighteen patients with a variety of solid tumors received a total of 40 cycles of carboplatin, 1,200 mg/m2 per cycle, administered by continuous infusion over 96 hours. All 40 courses were administered with a daily 4-hour intravenous (IV) infusion of either 5 or 10 micrograms/kg/d of recombinant human Escherichia coli-derived GM-CSF. The first 20 courses were administered without PBPC support (treatment A). Because of severe neutropenia and thrombocytopenia, the next 20 courses of therapy were administered with GM-CSF, PBPC, and oral antibiotic prophylaxis (treatment B). RESULTS The addition of PBPC support led to a significant reduction in the duration of neutropenia (10.5 v 7.5 days; P = .027) and thrombocytopenia (12.4 v 5.2 days; P = .001), number of RBC transfusions (six v three; P = .01) and platelet transfusions (10.3 v 3.7; P = .013), number of hospital days (12.6 v 2.9; P = .01), and days of IV antibiotics (11.8 v 2.4; P = .007) per cycle. Significant increases in the weekly dose intensity (206 v 285 mg/m2/wk; P = .014) and total dose (2,287 v 3,600 mg/m2; P = .018) of carboplatin delivered were also observed with treatment B. The overall response rate in this study was 70%, with 11 of 16 assessable patients achieving either a complete (three patients) or partial (eight patients) remission. CONCLUSION This combination of GM-CSF and PBPC infusion represents an effective method for delivering multiple cycles of high-dose carboplatin chemotherapy and may serve as a model for the administration of high-dose chemotherapy in future trials.

PURPOSE Combination chemotherapy regimens that include cisplatin (CDDP) and bleomycin (BLE) result in the cure of the majority of patients with malignant germ cell tumors of the testis. We investigated the long-term damage of such chemotherapy to renal, pulmonary, and hearing function. PATIENTS AND METHODS Forty-three patients with disseminated testicular carcinoma were studied 1.5 to 9.3 years (median, 4.1 years) after completion of chemotherapy. All 43 patients received CDDP; of these, 39 also received BLE, 27 vinblastine (VLB), and 27 etoposide (VP-16). Mean cumulative doses of individual cytotoxic drugs administered were CDDP 483 mg/m2 (range, 189 to 1,173 mg/m2), BLE 160 mg/m2 (range, 81 to 311 mg/m2), VLB 31 mg/m2 (range, 19 to 158 mg/m2), and VP-16 667 mg/m2 (range, 242 to 1,455 mg/m2). RESULTS In the majority of cases, values of renal, pulmonary, and hearing function were within the normal range before treatment. An initial decrease in renal, pulmonary, and hearing function was observed, with recovery of pulmonary function at late follow-up. On average, a decrease of 15% in creatinine clearance rates was observed at late follow-up. Long-term effect on audiometric function was considerable, but frequencies affected were outside the range of conversational speech. With multivariate analysis, no overall relation between the cumulative doses of the individual drugs and the loss in organ function was found; the cumulative doses of CDDP and BLE only contributed approximately 30% to the loss in renal function and vital capacity, respectively. CONCLUSION Chemotherapy-induced pulmonary toxicity is reversible, whereas nephrotoxicity and ototoxicity are not. However, the long-term effects of chemotherapy in testicular cancer patients were minor and not invalidating.

PURPOSE We report on long-term health-related problems determined from extended follow-up of 86 children and adolescents who were treated for paratesticular rhabdomyosarcoma on the Intergroup Rhabdomyosarcoma Studies I and II (IRS I-II). PATIENTS AND METHODS Patients were treated between 1972 and 1984, and ages at diagnosis ranged from 10 months to 19 years. The majority of these patients had initial retroperitoneal lymph node dissection (RLND) or sampling performed. RESULTS Problems related to surgical procedures included bowel obstruction in nine patients, loss of normal ejaculatory function in eight, development of a hydrocele in five, and lymphedema of the leg in five. Sequelae related to radiotherapy were difficult to assess with the exception of three patients whose remaining testes were in the field of radiotherapy. In general, kidney and bladder function were normal in patients who received radiotherapy to the paraaortic lymph nodes and/or bladder. Four patients who had abdominal radiotherapy had chronic diarrhea. Two patients had urethral strictures and urethritis. Four patients had bone or soft tissue hypoplasia in the field of radiotherapy. Chemotherapy-related late effects were primarily hemorrhagic cystitis or gonadal dysfunction after cyclophosphamide. A third of the patients who received cyclophosphamide developed hemorrhagic cystitis, and half of these had extended periods of gross hematuria after therapy was discontinued. The testicular size was small in children whose testes were irradiated and in some who received cyclophosphamide. Tanner staging was normal in 45 patients for whom it was recorded. Elevated follicle-stimulating hormone (FSH) values or known azoospermia occurred in more than half the patients for whom data were available. CONCLUSIONS A variety of sequelae related to therapy were determined in this patient population. These findings suggest that some aspects of therapy warrant reevaluation and that improved plans for follow-up care need to be provided.

PURPOSE A single-center phase II study was performed to evaluate the efficacy of recombinant interleukin-2 (rIL-2) administered by continuous infusion to patients with metastatic renal cell carcinoma (RCC). PATIENTS AND METHODS Thirty-one patients with RCC were entered onto the study. rIL-2 (Proleukin; Eurocetus Corp, Amsterdam, The Netherlands) was administered intravenously in a dose of 18 x 10(6) IU/m2 per 24 hours. A maximum of two induction cycles and four maintenance cycles were given. Each induction cycle consisted of two rIL-2 infusion periods of 120 hours and 108 hours duration, respectively; these were separated by a 6-day rest period. Each maintenance cycle consisted of a 120 hours rIL-2 infusion period. RESULTS Six of 30 assessable patients (20%) responded; two (7%) with a complete response (CR) and four (13%) with a partial response (PR). The response duration for patients with CR was 209 and 715+ days, and for those with PR 161, 197, 245, and 353 days. Seven patients had stable disease (SD) with a median duration of 261 days (range, 127 to 381 days). The overall median survival was 261 days (range, 13 to 905+ days). The most frequent toxicities requiring dose reductions of rIL-2 were: hypotension in 87% of patients, dyspnea in 32%, CNS toxicity in 55%, and an increase in serum creatinine levels in 48%. Septicemia occurred in 16% of patients. Toxicities usually reversed on interruption of rIL-2 infusion. One patient (3%) died as a result of the treatment from initial CNS toxicity followed by multiorgan failure. CONCLUSIONS The study confirmed the antitumor efficacy of rIL-2 administered by continuous infusion in patients with metastatic RCC. The response rate was similar to that obtained by high-dose bolus injections of rIL-2. Toxicity was substantial but manageable in a specialized oncology ward without routine use of an intensive care unit.

PURPOSE The doxorubicin analog, epirubicin (EPI), was tested in patients with malignant mesothelioma. PATIENTS AND METHODS Sixty-three patients with malignant mesothelioma were given EPI 110 mg/m2 every 3 weeks. Histology was reviewed and confirmed by a pathology panel. On the basis of unconvincing or wrong histology, insufficient material or cytology only, nine cases were considered ineligible for the study. None of the patients had received prior chemotherapy. RESULTS The main side effects were myelosuppression, alopecia, and gastrointestinal toxicity. Tumor response, assessed by computed tomographic (CT) scans, was assessable in 48 patients. Seven patients (15%) achieved a partial response that lasted a median of 37 weeks; 19 patients had stable disease, and 22 patients progressed on treatment. Median survival time was 40 weeks from the start of chemotherapy, and the median survival of responding patients was 87 weeks. One responding patient is still alive and free of relapse 4 years from the start of chemotherapy. CONCLUSION We conclude that further testing of EPI in malignant mesothelioma is warranted.

PURPOSE In an effort to minimize complications related to high-dose radiotherapy (RT), children with Hodgkin's disease are often treated with low-dose RT (less than 25 Gy) plus chemotherapy. We performed a retrospective study comparing the results in these children with those from children treated with higher doses of RT (30 to 40 Gy) with or without chemotherapy. PATIENTS AND METHODS From 1970 to 1988, 121 patients younger than 18 years of age with newly diagnosed Hodgkin's disease were treated at the Children's Hospital of Philadelphia (CHOP) and the Hospital of the University of Pennsylvania (HUP). Before 1977, most children underwent laparotomy and received high-dose RT with or without chemotherapy. Since then, high-dose RT alone has been reserved for pathologic stage IA and IIA postpubertal children without large mediastinal masses. In general, most postpubertal children with stage IIB through IVB disease or large mediastinal masses and all prepubertal children have received low-dose RT plus chemotherapy without laparotomy. RESULTS The 10-year actuarial survival for all children was 86%, and the event-free survival (EFS) was 67% (median follow-up, 6.6 years). For 58 children treated with low-dose RT plus chemotherapy, 10-year survival and EFS (median follow-up, 6.8 years) were 88% and 67%, respectively. The corresponding figures for 10-year survival and EFS in 48 children treated with high-dose RT with or without chemotherapy were 88% and 66%, respectively. In children receiving combined modality therapy, the in-field failure rate was 7% for sites given between 17.5 and 22.5 Gy and 2% for sites given more than 32.5 Gy. In children receiving RT alone, the failure rate was 5% for sites given more than 32.5 Gy. CONCLUSION We conclude that low-dose RT plus chemotherapy has yielded results comparable to those with higher doses of RT with or without chemotherapy.

PURPOSE Patients with non-Hodgkin's lymphoma (NHL) who do not achieve a complete response (CR) after induction chemotherapy or who relapse after achieving a CR are rarely cured of their disease by the usual salvage therapy. Success of high-dose cytotoxic therapy with an autologous bone marrow transplant (AuBMT) is limited. We describe the results of a prospective single-institution study using a new conditioning regimen for patients with relapsed or resistant NHL who underwent AuBMT. PATIENTS AND METHODS Forty-four patients were reinduced with cytotoxic therapy and then evaluated for response. All patients received the conditioning regimen of hyperfractionated total body irradiation (TBI), etoposide (VP-16), and cyclophosphamide (CTX) followed by autologous bone marrow reinfusion. RESULTS The disease-free survival (DFS) rate was 57% with a median follow-up of 42+ months. The only variable significantly associated with DFS was the patient's remission status at AuBMT. Patients who underwent AuBMT in CR had a DFS of 80%, whereas patients who underwent AuBMT in partial response (PR) or with progressive disease (PD) had a DFS of 60% and 11%, respectively (P = .002). The major toxicity was hemorrhage at the site of bulky disease, especially in patients with residual mediastinal and/or pulmonary disease. CONCLUSION Planned reinduction cytotoxic therapy followed by TBI, VP-16, and CTX with AuBMT is an effective treatment for patients with relapsed and resistant NHL.

PURPOSE In view of the pleomorphic role cytokines play in human lymphoproliferative disorders, we investigated the possible involvement of tumor necrosis factor-alpha (TNF) in hairy cell leukemia (HCL). PATIENTS AND METHODS The levels of TNF were measured in the serum of untreated patients, and in the culture supernatants of unstimulated and stimulated enriched hairy cells (HC). Furthermore, the presence of TNF mRNA transcripts in HC was analyzed. The possibility that HC could inhibit the in vitro growth of normal erythroid progenitors via the release of TNF was also investigated. Finally, in an attempt to correlate the circulating levels of TNF with the course of the disease, these were retested during and after treatment with interferon-alpha (IFN). RESULTS Significantly increased levels of TNF were found in the sera of untreated HCL patients compared with normal control sera were seen from patients with other diseases (P less than .001), with values greater than 10 pg/mL in 21 of 42 samples tested. A significant decrease (P less than .01) of TNF levels was recorded following IFN-2a administration in 16 cases with detectable pretreatment serum levels of TNF. In two cases, an increase in TNF values was associated with persistence or progression of disease. The likelihood that the circulating levels of TNF were caused by the pathologic cells is supported by the evidence that purified HC may release TNF spontaneously. The values can be markedly increased following in vitro activation with the phorbol ester 12-0-tetradecanoylphorbol-13 acetate (PMA), with B-cell growth factor (BCGF), and, to a further extent, with the combination of PMA and BCGF. Furthermore, the constitutive mRNA for TNF was found in seven of eight HC samples analyzed. Although supernatants of enriched HC, were capable of reducing the growth of normal bone marrow erythroid progenitors by 50%, duplicate experiments using an anti-TNF antibody produced an almost complete disappearance of the inhibitory effect. CONCLUSION The results of this study suggest that TNF plays an important role in the pathogenesis of the cytopenia(s) characteristically associated with HCL.

PURPOSE A phase II trial that uses liposome-encapsulated muramyl tripeptide phosphatidylethanolamine (L-MTP-PE) in patients with relapsed osteosarcoma is underway. To determine if in vivo cytokine induction plays a role in the mechanism of action of L-MTP-PE, we investigated the circulating cytokine levels of 16 patients who were undergoing therapy. PATIENTS AND METHODS Patients had histologically proven osteosarcoma and pulmonary metastases that developed either during adjuvant chemotherapy or that were present at diagnosis and persisted despite chemotherapy. Patients were rendered disease-free by surgery. The major goal of the study was to improve the disease-free interval in this high-risk group. L-MTP-PE 2 mg/m2 was infused during a 1-hour period twice a week for 12 weeks, then once a week for 12 weeks. Serial blood samples were collected after L-MTP-PE administration and were assayed for cytokine levels (tumor necrosis factor-alpha [TNF alpha] interleukin-1 alpha [IL-1 alpha], IL-1 beta, IL-6, interferon-gamma [IFN-gamma], neopterin, C-reactive protein). RESULTS After the infusion of L-MTP-PE, there was rapid induction of circulating TNF alpha and IL-6. TNF alpha levels peaked 1 to 2 hours after infusion in 10 of 16 patients, whereas peak IL-6 levels were detected at 2 to 3 hours in all patients. Induction of circulating TNF alpha and IL-6 was evident only after the first dose of L-MTP-PE. Neither IL-1 alpha nor IL-1 beta was detected in the plasma. Neopterin levels increased at 24 hours postinfusion, which indicated macrophage activation, and were not related to the induction of circulating IFN-gamma. C-reactive protein was elevated in all patients at 24 hours and decreased by 72 hours. Unlike circulating TNF alpha and IL-6, elevations in C-reactive protein and neopterin could be detected throughout the treatment course. CONCLUSION It is concluded that L-MTP-PE has specific biologic effects in patients with osteosarcoma that may be important to the drug's immunostimulatory capacity and its effectiveness as an antitumor agent.

PURPOSE The ability of growth factors to stimulate marrow recovery suggests their potential for use in dose intensification of cytotoxic drugs. We performed a phase I study of the alkylating agent thiotepa in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF), with the goal of dose-escalation of thiotepa. Thiotepa was selected based on its capacity for dose escalation to more than 1 g/m2 in the marrow transplantation setting. PATIENTS AND METHODS The starting dose of thiotepa (75 mg/m2) was the highest dose evaluated in our previous phase I trial. Thirteen patients received 22 courses of thiotepa and GM-CSF. The dose of GM-CSF was 10 micrograms/kg subcutaneously daily in six patients and 5 micrograms/kg in seven patients. RESULTS Three patients (23%) developed grade 3 to 4 neutropenia on the first course, with a recovery to more than 1000/mm3 in 4.7 days (mean). Recovery was as rapid with the 5 micrograms/kg as it was with the 10 micrograms/kg GM-CSF dose. Thrombocytopenia grade 3 to 4 affected seven of 13 (54%) patients in the first course; counts recovered to more than 50,000/mm3 in a median of 15 days. GM-CSF at either dose did not influence markedly the severity or duration of thrombocytopenia, and did not permit dose escalation of thiotepa. Among the seven patients who received a second cycle of treatment, six of seven experienced grade 3 or 4 thrombocytopenia that lasted a median of 15.5 days. Five had thrombocytopenia that lasted more than 35 days after one to three cycles of treatment. Plasma concentrations of thiotepa and tepa were measured by gas chromatography in eight patients. The plasma elimination of thiotepa fit a two-compartment open model with a harmonic mean terminal half-life of 2.44 hours. The mean total body clearance was 217.9 mL/min/m2, and the mean steady-state volume of distribution (Vdss) was 36.8 L/m2. The half-life of tepa was 7.98 hours, and the ratio of the area under the plasma concentration versus time curve (AUC) of tepa to that of thiotepa was 0.79. CONCLUSIONS These data were consistent with our previous observations at this dose, and indicated that the severity of toxicity in these patients was not explained by aberrant pharmacokinetic indices. We conclude that, independent of effects on neutropenia, severe and cumulative platelet toxicity precludes further escalation of thiotepa dose despite the use of GM-CSF.
