A double-blind trial comparing antiemetic efficacy and toxicity of metoclopramide versus methylprednisolone versus domperidone in patients receiving doxorubicin chemotherapy alone or in combination with other antiblastic agents.

Nausea and vomiting are reported in approximately 60% of neoplastic patients treated with doxorubicin used alone at doses greater than or equal to 50 mg/m2 or in combination with other noncisplatin antiblastic agents. In a double-blind study we compared the efficacy and tolerability of metoclopramide (MTC) versus Domperidone (DMP) versus methylprednisolone (MP) administered intravenously (i.v.) to inpatients. Forty-four patients entered the trial. The three antiemetic regimens were found equally effective. A complete protection from vomiting/nausea was obtained in 14/11 (93.3%/73.3%) of patients treated with MTC, in 15/14 (100%/93%) of those treated with MP and in 11/11 (78.6%/78.6%) of those treated with DMP. Side effects were slight and not significantly different among the three regimens. In conclusion, i.v. MTC and MP (DMP is no longer available in i.v. formulation) as single agents are an adequate treatment for prevention of nausea and vomiting induced by doxorubicin alone or in combination with other noncisplatin antiblastic agents.

Methylprednisolone versus metoclopramide for prevention of nausea and vomiting in breast cancer patients treated with intravenous cyclophosphamide methotrexate 5-fluorouracil: a double-blind randomized study.

The antiemetic efficacy and toxicity of methylprednisolone (MP) and metoclopramide (MTC) in prevention of nausea and vomiting in breast cancer patients receiving intravenous cyclophosphamide methotrexate 5-fluorouracil (CMF) chemotherapy has been evaluated in a double-blind trial. The two antiemetic drugs (MP vs. MTC) offered the majority of patients a similar complete protection from vomiting (76.5 vs. 66.7%) and nausea (82.4 vs. 81.8%), but in older patients MTC seems more efficacious than MP. Sedation was found more frequently (p = 0.02) in patients treated with MTC. In conclusion, in patients treated with CMF the use of MP as preventive therapy of nausea and vomiting is to be preferred to MTC due to its better tolerability, but in older patients MTC should be considered if MP fails.

A prospective randomized double-blind crossover study comparing the antiemetic activity of alizapride and metoclopramide in patients receiving cisplatin chemotherapy.

We designed a double-blind randomized crossover study to compare the antiemetic activity and toxicity of high-dose intravenous alizapride (3.5 mg/kg) versus high-dose intravenous metoclopramide (1 mg/kg) both combined with intravenous methylprednisolone in 40 untreated cancer patients submitted to cisplatin chemotherapy alone. The mean number of vomiting episodes (3.6 vs. 1.0), length of vomiting (209.8 vs. 80.9 min), and rate of complete prevention of vomiting (25% vs. 68.4%) at first cycle were in favor of metoclopramide, with a statistically significant difference. This difference was not statistically significant in the second cycle after crossover. Toxicity of both treatments was mild and diarrhea was more frequent in the alizapride-treated patients. Preference expressed by the patients was also in favor of metoclopramide. We conclude that alizapride offers less antiemetic protection than metoclopramide in patients receiving cisplatin chemotherapy. Further use of alizapride in such patients is not recommended.

Treatment of advanced non-small cell lung cancer (NSCLC): the "Umbria" cooperative study.

One hundred fifty-six patients with metastatic or locally advanced non-small cell lung cancer (NSCLC) were randomized to 3-week cycles of treatment with either: (A) cisplatin (120 mg/m2 on day 1); (B) cisplatin (120 mg/m2 on day 1) plus etoposide (VP-16) (100 mg/m2 on days 1-3; and (C) the cisplatin plus etoposide (VP-16) regimen plus mitomycin C (10 mg/m2 on days 1, 21, and 42; then every 6 weeks for a maximum dose of 100 mg). The overall objective response rates for the combination regimens (30% with two drugs and 26% with three drugs) were superior to that obtained with one drug (4%). Likewise, the median duration of survival with the combination therapy arms (8 to 9 months) was superior to that obtained with the single agent (5 months). Both performance status and limited disease were correlated with response in all groups, and with survival in the combined chemotherapy arms. The dose-limiting toxicity was myelosuppression, especially for the group receiving the three-drug regimen. In summary, combination chemotherapy using cisplatin and etoposide (VP-16) appears to be the most active and safest regimen in NSCLC.

Immunologic profile in patients with Hodgkin's disease in complete remission.

Mononuclear cell subsets in peripheral blood, in vitro production of interleukin-2 (IL-2) and gamma interferon (IFN gamma), spontaneous cell-mediated cytotoxicity (SCMC) and circulating levels of Type I IFN, neopterin, beta-2 microglobulin (B2-M), immunoglobulins and complement fractions were studied in 33 patients with Hodgkin's disease (HD) in complete remission. The mean percentages, but not the absolute numbers, of T-lymphocytes expressing pan-T markers (OKT11, OKT3, ER, E-AET R) were significantly decreased compared with control values. Furthermore, patients showed a selective loss of OKT4+ cells, as well as increased percentages and numbers of Leu7+ and OKIa+ lymphocytes, and of OKM1+, LeuM2+, and LeuM3+ cells. OKT4+ cell depletion was a characteristic of patients with shorter time since beginning of remission as well as of those with nodular sclerosis (NS), mixed cellularity Hodgkin's disease (MC-HD), and systemic symptoms at diagnosis. Multifactorial statistical analysis carried out to investigate the effect of disease characteristics and the time since remission began on peripheral mononuclear blood cell (PMBC) subsets showed that histologic condition was the single best predictor of T-cell pool or OKT4+ cell subset size. Time since remission duration and other disease-related factors determined differences in the percentages, but not in the absolute numbers, of T-cell fractions. In addition, neither the disease features nor the time since remission duration determined significant differences in the absolute number of non-T-mononuclear cells in the various patient groups. Patients displayed decreased in vitro synthesis of IL-2 and IFN gamma. The values of SCMC, Type I IFN, neopterin, B2-M, immunoglobulins, and complement fractions did not differ greatly from those of controls.

Double-blind controlled trial of the antiemetic efficacy and toxicity of methylprednisolone (MP), metoclopramide (MTC) and domperidone (DMP) in breast cancer patients treated with i.v. CMF.

Sixty-two patients treated for the first time with i.v. CMF were included in a double-blind comparative study aimed at evaluating the efficacy of 3 different drugs (methylprednisolone (MP), metoclopramide (MTC), and domperidone (DMP) in preventing chemotherapy-induced nausea and vomiting. Complete protection from vomiting/nausea was obtained in 85%/80% in the group treated with MP; in 60%/65% in the group treated with MTC and in 38%/42% in the group treated with DMP. Average number of vomiting episodes was 2.4 with MP, and 1.7 with MTC and 6.2 with DMP. Older patients seem to be a prognostically unfavorable subgroup. Side-effects were mild and infrequent. We conclude that MP and MTC are probably equally efficacious antiemetic treatments in patients undergoing i.v. CMF chemotherapy, but due to the risk of extrapyramidal reactions with MTC, MP probably should be the treatment of choice in these patients.

Antiemetic activity of high doses of metoclopramide combined with methylprednisolone versus metoclopramide alone in cisplatin-treated cancer patients: a randomized double-blind trial of the Italian Oncology Group for Clinical Research.

We designed a multicenter, double-blind randomized study to determine the safety and antiemetic effectiveness of intravenous (IV) methylprednisolone (P) combined with high-dose IV metoclopramide (MTC) v MTC alone in 200 untreated cancer patients receiving cisplatin chemotherapy. One hundred eighty-five patients were evaluable for treatment efficacy. MTC plus P was significantly superior to MTC alone in reducing the number and length of vomiting episodes (P = .001 and P = .0008, respectively) and the maximal intensity of nausea (P = .0124 with a score system; P = .0155 with a linear analogue scale) and length of nausea (P = .0056). The subgroup with a major incidence of nausea and vomiting was women, especially young women, outpatients, and those treated with higher doses of cisplatin. Side effects were low and equally distributed between the two treatment groups. We conclude that MTC plus P has greater antiemetic activity than MTC alone in patients receiving cisplatin chemotherapy.

A phase II antiemetic combination (COMD) for cisplatin-induced nausea and vomiting.

Thirteen patients resistant to high-dose metoclopramide (greater than or equal to 5 emetic episodes in 24 h following chemotherapy) were treated in the subsequent course of CDDP chemotherapy with COMD (chlorpromazine, orphenadrine, metoclopramide, dexamethasone). A statistically significant reduction in the number of vomiting episodes was obtained, and 69% of patients showed a better acceptance of CDDP treatment. Subsequently, the same antiemetic combination was administered to 31 untreated patients receiving CDDP alone for the first time: 67.7% obtained complete protection from vomiting with minimal toxicity. According to our experience, COMD is an efficacious and well-tolerated antiemetic combination in cisplatin-treated patients; however, further studies with larger numbers of patients are required to confirm these preliminary results.

Evaluation of the antiemetic activity of bromopride in cancer patients treated with i.v. CMF.

In more than 70% of patients undergoing surgery for breast cancer with histologically positive lymph nodes, precautional therapy with CMF (cyclophosphamide, methotrexate, 5-fluorouracil) causes nausea and vomiting. At the present time, the optimal antiemetic therapy has not been found. From May 1983 to March 1984, 35 patients, of whom 34 were evaluable, were entered in a randomized double blind antiemetic treatment with either bromopride (16 patients), a procainamide derivative structurally similar to metoclopramide, or placebo (18 patients). Bromopride (20 mg) and the placebo were administered in a 3-min i.v. injection half an hour before chemotherapy and at 3 1/2 and 7 1/2 following chemotherapy. A complete antiemetic protection was obtained in 9 patients (56.3%) treated with bromopride compared to 5 patients (27.8%) treated with the placebo. A major antiemetic (less than or equal to 2 vomiting episodes) was obtained in 3 patients (18.7%) treated with bromopride compared to 5 patients (27.8%) treated with the placebo. Statistical analysis showed a trend in favor of bromopride (P = 0.058). The most frequent side effect was sedation reported in 6 patients (37.5%) treated with bromopride and 2 patients (11.1%) treated with the placebo (P = 0.06). The study was interrupted when several patients presented vomiting episodes more than 12 h after CMF administration, and thus beyond the foreseeable protective effect of the antiemetic treatment. It is our opinion that the search for an optimal antiemetic regimen in the course of i.v. CMF therapy should consider the administration of antiemetic drugs at least until 12 h after chemotherapy.

Preliminary observation on the clinical tolerance of interferon-beta in cancer patients.

Nine patients with metastatic solid tumors were given IFN-beta by i.v. bolus injections. Six escalating doses (from 1 to 9 X 10(6) IU) followed by 6 additional injections at the dose of 9 X 10(6) IU were administered every other day (schedule A) in 3 of the 9 patients. IFN dose was also increased to a maximum of 46 X 10(6) IU, and 12 individual injections of 1, 2, 3.3, 5, 7, 9, 12, 16, 21, 27, 34 and 46 X 10(6) IU of IFN were given over a minimum of a 24-day period (schedule B) in 6 of the 9 patients. The single maximal tolerated dose ranged from 9 to 46 X 10(6) IU. The toxicity of IFN-beta given as scheduled in this study was significant but acceptable.

Immunorestorative properties of thymostimulin (TS) in patients with Hodgkin's disease in clinical remission.

Fifteen Hodgkin's disease patients (8 male, 7 female) aged 19-72 years, who had been in complete unmaintained remission for 1 year or more when the study was initiated, were given 50 mg thymostimulin (TS) IM daily for 60 consecutive days. When compared with 26-30 age- and sex-matched controls, as a group the patients' circulating ENR+, OKT+3, and OKT+4 cells were depressed (0.001 less than or equal to P less than or equal to 0.06), whereas their OKT+8 cell population was not. Low (greater than 1 SD or greater than 2 SD below mean in controls) or borderline (mean value of two subsequent tests greater than 1 SD below mean in controls) values of ENR+, OKT+3, and OKT+4 cells were seen in nine (group I) of the 15 patients tested, while the remaining six patients (group II) had normal T-cell proportions. Following TS treatment, the proportions of ENR+, OKT+3, and OKT+4 cells increased to normal in all group I patients. The T-cell levels, however, decreased to pretreatment values 60-70 days after completion of TS therapy. TS had no effect on the group II patients whose T-cell percentages had initially been normal. Spontaneous cell-mediated cytotoxicity (SCMC) was assessed in 11 patients, and irrespective of the baseline values, there was a significant enhancement (P less than 0.005) by day 15 of TS administration, which was maintained during treatment. SCMC, however, returned to pretreatment levels 60-70 days after TS was discontinued. The delayed skin test reactivity to DNCB was significantly depressed in all cases. Although TS restored the T-cell proportions, it failed to reverse DNCB reactivity from negative to positive in any of the patients tested. TS can thus restore defective T-cell frequencies and can enhance cytolytic functions that are potentially important in host immunosurveillance, but it apparently failed to improve the skin reactivity to neoantigen.

Antiemetic activity of two different high doses of metoclopramide in cisplatin-treated cancer patients: a randomized double-blind trial of the Italian Oncology Group for Clinical Research.

High-dose metoclopramide has been proposed as an effective antiemetic agent in patients treated with cisplatin. Its optimal dosage schedule, however, has not yet been completely defined. We report the results of a multicenter, double-blind, randomized clinical trial where the efficacy and safety of two fixed high-dose regimens of metoclopramide (60 and 120 mg, respectively) have been tested in 112 patients receiving cisplatin treatment. No statistically significant difference has been found between the two groups. In patients treated with cisplatin at doses greater than 100 mg/m2, the higher dose regimen seems more efficacious, but this result should be confirmed in a larger group of patients. Treatment was generally well-tolerated. However, a consistent percentage of patients (about 60%) still present with vomiting, and this makes further investigation necessary.

5-Fluorouracil, vincristine and hydroxyurea combination chemotherapy in metastatic colorectal cancer.

Twenty consecutive patients who had biopsy proven metastatic colorectal cancer were treated with combination chemotherapy. The drug regimen (FVH), in a 4 week cycle, consisted of 5-fluorouracil (600 mg/m2 i.v. on days 1, 8, 15 and 22), vincristine (1.4 mg/m2 i.v. on day 4), and hydroxyurea (2400 mg/m2 p.o. on days 3, 10, 17 and 24). Three of the 18 evaluable patients achieved an objective tumor remission (2 CR and 1 PR) and 15 patients had stable disease. The overall response rate to FVH was therefore not superior to that achieved in patients who received 5-fluorouracil alone, and the overall survival in this study was comparable to that of other studies involving patients with metastatic colorectal cancer.

Cell membrane markers and phytohemagglutinin reactivity of circulating lymphocytes from chronic myelocytic leukemia patients.

Lymphocytes from 22 patients with chronic myeloid leukemia (CML), 13 treated with polychemotherapy, eight by monochemotherapy, and one untreated, were analyzed for the presence of classic T and B cell surface markers (E-rosette, EAC-rosette, surface immunoglobulins) and for their ability to respond to phytohemagglutinin (PHA). The absolute number and percentage of E-rosetting cells (T-cells), EAC-rosetting cells and cells staining for surface immunoglobulins (B cells) were all significantly lower than controls (P less than or equal to 0.025). The response to PHA was also significantly lower in patients than in controls at the smaller concentrations of the mitogen (3.75 micrograms/ml, 30 micrograms/ml) tested (P less than or equal to 0.01); at a higher PHA concentration (120 micrograms/ml) the decrease in PHA stimulation approached significance (P = 0.07). These lymphocyte abnormalities support the concept that CML lymphocytes may be derived from the leukemic clone.

The in vitro effect of a calf thymus extract (thymostimulin) on the immunologic parameters of patients with untreated Hodgkin's disease.

The in vitro effect of a calf thymus extract, thymostimulin (TP--1), on the E-rosette-forming capacity and on the PHA blastogenic response of peripheral blood lymphocytes was evaluated in 20 patients with untreated Hodgkin's disease. The mean percentage of lymphocytes forming E rosettes increased in patients from 44.2% to 57.5% (P less than 0.005). The mean PHA stimulation index rose with all three concentrations tested, but returned to the normal range only with the highest PHA concentration (60 mu/ml). An increase in the immune parameters was greatest in those patients who presented with decreased E-rosetting cells of total lymphocyte counts or whose disease was Stage III or IV or of mixed cellular histology.

Inhibition of spontaneous platelet aggregation and adhesion by indobufen (K 3920). A randomized, double-blind crossover study on platelet, coagulation and fibrinolysis function tests.

In a randomized double-blind crossover study in 12 patients with atherosclerotic disease, the effect of 2 dosages (100 and 200 mg twice daily) of indobufen, a new synthetic inhibition of platelet aggregation, on some platelet functions, coagulation and fibrinolysis tests was investigated. Regardless of the dosage used, indobufen was shown to induce a prompt normalization of the enhanced platelet aggregation of these patients. The effect lasted for the entire period of drug administration and in 50% of patients a normal platelet aggregation was maintained until the fourth day after discontinuation of the drug. Indobufen was also able to reduce platelet adhesiveness and to lengthen bleeding time, especially when the higher dosage was used.
