To improve the safety of autotransplantation for myeloma, peripheral blood stem cell (PBSC) collection was attempted in 75 previously treated patients after the administration of high-dose cyclophosphamide (HD-CTX; 6 g/m2) with or without granulocyte-macrophage colony-stimulating factor (GM-CSF). Sixty patients subsequently received melphalan 200 mg/m2 (57 patients) or melphalan 140 mg/m2 and total body irradiation (850 cGy) (3 patients) supported by both autologous bone marrow and PBSC; 38 patients received GM-CSF posttransplantation. Among 72 patients undergoing PBSC apheresis, "good" mobilization (greater than 50 colony-forming units granulocyte-macrophage [CFU-GM] per 10(5) mononuclear cells) was achieved when prior chemotherapy did not exceed 1 year and when GM-CSF was used post-HD-CTX; similarly, rapid platelet recovery to 50,000/microL within 2 weeks was associated with "good" PBSC mobilization. These same variables also predicted for rapid engraftment after autotransplantation, so that hematologic recovery (granulocytes greater than 500/microL and platelets greater than 50,000/microL) proceeded within 2 weeks among the 37 patients with "good" PBSC collection. As a result of rapid neutrophil recovery (greater than 500/microL) within a median of 2 weeks, infectious complications both post-HD-CTX and posttransplant were readily manageable, resulting in only one treatment-related death post-HD-CTX. The cumulative response rate (greater than or equal to 75% cytoreduction) for all 75 patients was 68%, with 12-month event-free and overall survival projections of about 85%. Using both bone marrow and PBSC together with GM-CSF, autotransplants are safe and appear effective in myeloma, especially when prior therapy had been limited to less than 1 year. More than 80% of transplanted patients achieved complete hematologic recovery within a median of 1 month posttransplant (granulocytes greater than 1,500/microL; platelets greater than 100,000/microL; hemoglobin greater than 10 g%), thus providing sufficient hematopoietic reserve for further chemotherapy in the event of posttransplant relapse.

A retrospective analysis was made of elderly cancer patients (pts) who were treated with cancer chemotherapy in our Department of the Cancer Inst. Hosp. There were 180 pts above age 70 years at the start of chemotherapy between July of 1974 and December of 1988. Characteristics of these 180 pts were as follows: (1) 73 years of age in median (70-89 years), (2) 67 pts with malignant lymphoma (37%); 40 with lung ca. (22%), 20 with breast ca. (11%), stomach ca., colorectal ca., multiple myeloma and other; (3) Combination chemotherapy given to 174 pts; (4) OUTCOME: 41 pts (23%) were alive as September of 1989, and autopsy performed in 66 out of 87 pts who died in the hospital (76%). There were no special chemotherapeutic regimens only for elderly pts. Intensity of adequate chemotherapy based on therapeutic protocols was evaluated, dividing pts into two groups: full-dose group and reduced-dose group. Most pts (96%) with small cell lung cancer (SCL) were treated on protocols. For example, 12 elderly pts with SCL were treated with VEC regimen (VCR.VP-16.CTX); eight pts with full-dose and four reduced-dose, and their response rate (CR/PR) of 50%/38% and 25%/75%, respectively, and in 23 younger pts; 20 full-dose and three reduced-dose, and response rate 35%/35% and 33%/33%, respectively. There were 40 pts with acute non-lymphocytic leukemia over 60 years old, treated at Jikei University and in our Department. CR rates of these pts according to age showed a lower percentage with advancing age. Elderly pts with malignancies responsive to chemotherapy should be treated with the same regimen used in younger pts. But doses of each drug have to be adjusted to organ functions of each pt. patients with unresponsive malignancies, must be enrolled in clinical trials, and their responses and toxicities evaluated by age-stratified analysis.

Using the MOPC 104E murine plasmacytoma model, Ghanta et al have shown major synergism when cisplatin was added to a treatment program with BCNU and cyclophosphamide (CTX). To evaluate possible synergism in the treatment of human multiple myeloma (MM), 23 evaluable patients who had relapsed with standard treatment were treated with cisplatin, BCNU, CTX, and prednisone. There were five good and four fair responses in this group of heavily pretreated patients. These included responses in four patients who had failed to respond to or had relapsed with BCNU, CTX, and prednisone therapy at higher doses than those used in this protocol, indicating that there is synergism from the addition of cisplatin in the treatment of human MM. Gastrointestinal toxicity was significant but acceptable. Transient renal and hematologic toxicity was also seen. The number of responses and the apparent synergism seen suggest that this combination of drugs should be studied as therapy for untreated patients with MM, especially those with poor prognostic features.

Fifteen patients with multiple myeloma, two of whom had plasma cell leukemia, were treated between May 1974 and December 1978. Peptichemio was administered intravenously at doses of 40-80 mg/48 h, courses including 4-17 administrations in association with moderate doses of prednisone (15-50 mg/day) and androstanes at high dosages (250 mg weekly). In two patients PTC was associated with vincristine (VCR) administered on the first day of the course. Eight patients were previously untreated, four had been resistant to melphalan (MPH) and/or cyclophosphamide (CTX), and three had been treated irregularly with one or both of these alkylating agents. The criteria of response to therapy are reported. Out of a total of 15 PTC courses administered we obtained 13 responses, eight complete and five partial; no response was achieved in the other two patients. In the four patients who were resistant to MPH and/or CTX we obtained three responses, which were maintained with the same alkylating agent to which they had been resistant previously. The time needed to obtain a response in 90% of the patients was 6 weeks. Peptichemio was shown to be effective in patients in an advanced stage of the disease, in patients with light-chain myeloma and in those with plasma cell leukemia. The association of VCR potentiated the antitumor effect, but also increased the myelotoxicity. The PTC treatment was well tolerated. It is suggested that PTC be used in induction treatment of myelomatosis and in patients resistant to traditional alkylating agents.

The combination of a cyclophosphamide (CTX)-based chemotherapy regimen and interleukin-2 (IL-2) has been shown to provide synergistic effects against malignancy in animal models. We therefore conducted a phase I-II trial combining CTX-based combination chemotherapy or CTX alone with high-dose IL-2 in patients with advanced and refractory malignant disease. Fifteen patients with hemato-oncological malignancies (malignant lymphoma 8, multiple myeloma 3, solid tumor 2, leukemia 2) were enrolled in the study. Continuous high-dose IL-2 infusion was shown to be safely administered, starting as soon as recovery of white blood cell count. All patients developed rebound lymphocytosis 24-48 h after termination of IL-2 infusion. Although grade IV toxicity was observed in 5 patients (7 episodes), all side effects completely subsided. Triple chemotherapy (CTX, etoposide and Ara-C) seemed rather toxic (in this group of heavily treated patients) while CTX alone was well tolerated. Four out of 13 (31%) evaluable patients had partial response and another patient (7%) had stabilization of disease progression lasting 2-8 months. Our conclusion is that the combination of CTX and continuous infusion of IL-2 is feasible and should be investigated in patients with various malignant neoplasms.

Although urinary measurements of collagen degradation provide valid estimates of bone resorption, their clinical application is hampered by pronounced analytical and biological variability. Therefore, immunoassays for the determination of such parameters in serum have been developed. In this study, we assessed the performance of three new serum markers of bone turnover, i.e., C-terminal and N-terminal telopeptides of type I collagen (S-CTX and S-NTX) and bone sialoprotein. Results were compared with urinary total pyridinoline, total deoxypyridinoline, and urinary C-terminal telopeptides of type I collagen (U-CTX) and urinary N-terminal telopeptides of type I collagen (U-NTX). The study population included healthy men (n = 27), premenopausal (n = 30) and postmenopausal (n = 31) women, patients with hepatic dysfunction (HF, n = 24), renal failure (RF, n = 30), breast cancer without (BC-, n = 24) and with (BC+, n = 30) bone metastases, primary vertebral osteoporosis (OPO, n = 27), primary hyperparathyroidism (PHPT, n = 16), active Paget's disease of bone (n = 18), multiple myeloma (MM, n = 18), and patients with hypercalcemia of malignancy before and after treatment with pamidronate (HOM, n = 28). Changes in urinary and serum markers were similar in most metabolic bone diseases. However, differentiation between healthy controls and OPO, or PHPT, was improved by the serum markers. In MM, all serum and urinary markers were elevated (p < 0. 05 vs. controls). In BC+, skeletal involvement was reflected by significant increments in all indices (p < 0.01 vs. BC-), except U-CTX and S-CTX. In HOM, pamidronate-induced changes in biomarkers were most pronounced for U-CTX and S-CTX and S-NTX. HF and RF were associated with elevated levels of all serum markers (p < 0.05 vs. controls). In conclusion, measurements in serum reflect bone resorption to the same extent as the urinary indices. Since serum markers circumvent some of the limitations of urinary measurements, their use potentially improves the assessment of skeletal disorders.

An interim report evaluating the feasibility of myeloablative therapy followed by peripheral blood stem cell (PBSC) autotransplant in patients aged >60 years is presented. In the last 2 years 19 patients >60 years old with several oncological conditions, mostly hematological, underwent PBSC autotransplant either as salvage therapy following relapse or resistance to conventional treatment, or as consolidating therapy as a part of a well defined protocol. There were 13 males and six females; the mean age was 66.9 years (range 61-76 years); nine patients had resistant or relapsed lymphoma, six myeloma, two acute leukemia, one Waldenstrom's disease and one lung cancer. Myeloablative schemes included BEAM exclusively for lymphomas, busulfan and melphalan (Bu-MPH) mainly for myeloma, busulfan and cyclophosphamide (Bu-CTX) for lymphomas and leukemia and VP-16 and CTX for lung cancer. Mobilization of CD34+ cells was achieved in all patients with the combination of high-dose CTX and G-CSF with collections between 2.83 to 19.04 x 10(6)/kg (mean 7.1). All patients engrafted with a median time for recovery of PMN (>0.5 x 10(3)/microl) of 10 days (range 8-12 days) and for PLT (>20 x 10(3)/microl) of 12 days (range 10-17 days). Major responses were obtained in 15 of 16 patients evaluable for response and eight patients entered CR; overall eight patients are in CR, five are alive with disease, five are dead from disease progression and one is dead because of congestive heart failure 7 months following PBSC autotransplant. No early deaths following the procedure occurred; major side-effects were grade I-II mucositis (58%), fever with documented sepsis (10%), pneumonia (5%), cardiac, renal and liver toxicity (5%). Cardiac function was evaluated before and after myeloablative therapy by VEF in all patients; no significant modifications were necessary. In conclusion, our experience demonstrates that myeloablative therapies in older selected patients can be feasible; the feasibility of introducing PBSC autotransplantation following myeloablative therapy as a front-line treatment in patients aged >60 years, needs accurate guide lines for selection of appropriate patients.

Multiple myeloma causes extensive bone remodeling. Classical biochemical markers such as urinary calcium have poor sensitivity for detecting multiple myeloma bone remodeling. New biochemicals have been developed including a carboxyterminal telopeptide of collagen I (CTX). We used an immunoenzymatic assay to determine urinary CTX in 60 patients with multiple myeloma. This marker was evaluated with regard to total pyridinolines, urinary calcium, radiological features, pain and response to treatment with bisphosphonates. In patients with bone involvement, CTX concentrations were significantly higher (+230%) than those of deoxypyridinoline (DPD) (+175%) and pyridinolines (PYD) (+130%). In all patients we have found a close correlation between CTX and DPD but not between CTX and PYD. Compared to radiological features, CTX was more sensitive (97%) and specific (96%) than DPD. After treatment by bisphosphonates, the fall in CTX concentrations was paralleled to urinary calcium and more marked than pyridinolines. Although our results need to be confirmed, CTX appears to be a potential marker to explore bone involvement in multiple myeloma.

We report the results of a dose-intense chemotherapy regimen designed to rapidly induce remissions in patients with advanced multiple myeloma (MM). Patients received VAD for 3-6 cycles depending on response kinetics. This was followed by three sequential cycles of cyclophosphamide (CTX) at 3 g/m2 every 15 days with G-CSF support. 71% of these patients had stage IIIa, 23% had renal failure. The median age was 58, median beta-2 microglobulin 4.6 and median albumin was 3.5, indicating poor prognosis. Of 35 patients, 66% achieved a complete response (CR) (SWOG). Six patients (18%) had a partial response. Fifty percent of the patients with renal failure recovered their kidney function. High-dose CTX contributed to tumor-mass reduction particularly in patients presenting with high-tumor burden. Tumor-mass reduction following three pulses of dexamethasone (4 days each) is significantly higher than with one pulse (p < 0.005). While high beta-2 microglobulin and LDH levels (p < 0.05) were associated with poor outcome, patients who responded faster to chemotherapy had a longer survival (p = 0.005). We conclude that this regimen is safe and effective. A rapid response may be useful in selecting patients who may benefit from further high dose chemotherapy and stem cell support.

To explore the antitumor activities of KRN7000 in a NS-1 myeloma-bearing mice and the underlying mechanisms, cytotoxic activities of the spleen cells treated with KRN7000 in vivo and in vitro were examined with Yac-1 (a NK-sensitive cell line) and NS-1 (a NK-insensitive cell line) as the targeted cells. The life span of NS-1 myeloma-bearing mice was observed after treating with KRN7000 and combined with cyclophosphamide (CTX). Furthermore, toxicities of KRN7000 administration on liver and kidney were evaluated. The results showed that KRN7000 enhanced NK cytotoxic activities of spleen cells. Around 20% of NS-1-bearing mice survived after KRN7000 administration and the survival rate reached up to 80% of NS-1-bearing mice when KRN7000 was used in combination with CTX at a dose of 100 mg/kg (P < 0.005). KRN7000, at a dose of 100 micro g/kg, had no toxic effects on liver and kidney. These findings suggest that KRN7000 might be a promosing agent in tumor immunotherapy.
