A woman with multiple myeloma relapsed after 6 years of satisfactory tumor control with melphalan therapy. When progression then occurred, she was given exogenous human leukocyte interferon, 3 x 10(6) reference units twice daily i.m., as the sole therapy. Side-effects of the interferon therapy consisted of fever reactions and thrombocytopenia. One month after the initiation of interferon therapy there was 1) improvement of general health with less pain and tiredness, 2) reduction of the M-component, IgG-lambda, in the serum, and 3) a reduced plasma cell concentration in the bone marrow. After 5 months of interferon therapy tumor progression occurred despite continuous interferon treatment. At the same time, the tumor cells were less sensitive to interferon in in vitro tests than prior to interferon therapy. It is suggested that interferon therapy should be given as initial treatment to a few patients with multiple myeloma in a phase I trial.

Valproic acid is a new antiepileptic drug. It has a marked effect on generalized spike-wave discharges. The exact mechanism of action is uncertain; however, some evidence suggests an effect on the metabolism of gamma-aminobutyric acid. It is rapidly absorbed from the gastrointestinal (GI) tract. Concurrent administration with phenobarbital may result in elevated phenobarbital plasma concentrations. Administration with phenytoin sodium may transiently result in lower total phenytoin plasma levels. Side effects are generally mild and include fatigue, GI disturbances, weight gain, a fine postural and resting tremor, mild thrombocytopenia, and an increase in hepatic enzymes. Platelet counts and liver function monitoring should be done during valproic acid therapy. Drowsiness may be seen in patients receiving other antiepileptic drugs concurrently.

Fifty consecutive patients with blastic chronic myelogenous leukemia were evaluated clinically, morphologically, biochemically, and therapeutically. Forty-five patients had a preceding stable phase (38 Ph'+, 7 Ph'-); five patients presented with de novo Ph+ blast crisis. The most frequent clinical signs of impending blast crisis were weakness, fatigue, increasing splenomegaly, anemia, thrombocytopenia, marrow fibrosis, and a rising neutrophil alkaline phosphatase. Fever (unrelated to infection), skin infiltration, lymphadenopathy, hepatomegaly, thrombocytosis, and basophilia were much less common. The development of aneuploidy occurred in less than one-half of the total group. Myeloblastic morphology at blastic transformation was most frequent with occasional lymphoblastic, promyelocytic, and undifferentiated cases seen. Terminal deoxynucleotidyl transferase was present in one-third of the patients, but had no clear-cut relationship to the morphology. Response to treatment was generally disappointing (two complete and 15 partial remissions in 45 treated patients).

Shi-Quan-Da-Bu-Tang (Ten Significant Tonic Decoction), or SQT (Juzentaihoto, TJ-48) was formulated by Taiping Hui-Min Ju (Public Welfare Pharmacy Bureau) in Chinese Song Dynasty in AD 1200. It is prepared by extracting a mixture of ten medical herbs (Rehmannia glutinosa, Paeonia lactiflora, Liqusticum wallichii, Angelica sinesis, Glycyrrhiza uralensis, Poria cocos, Atractylodes macrocephala, Panax ginseng. Astragalus membranaceus and Cinnamomum cassia) that tone the blood and vital energy, and strengthen health and immunity. This potent and popular prescription has traditionally been used against anemia, anorexia, extreme exhaustion, fatigue, kidney and spleen insufficiency and general weakness, particularly after illness. In order to restore immunity in cancer patients, potentiate the therapeutic effect and ameliorate adverse toxicity of anticancer agents, 116 Chinese herbal formularies (Kampo) have been screened and evaluated. Fifteen compounds were found to have such actions. Among these, SQT was selected as the most effective as a potent biological response modifier. During the last eight years, animal models and clinical studies have revealed that SQT demonstrates extremely low toxicity (LD50 > 15 g/kg op murine), self-regulatory and synergistic actions of its components in immunomodulatory and immunopotentiating effects (by stimulating hemopoietic factors and interleukins production in association with NK cells, etc.), potentiates therapeutic activity in chemotherapy (mitomycin, cisplatin, cyclophosphamide and fluorouracil) and radiotherapy, inhibits the recurrence of malignancies, prolongs survival, as well as ameliorate and/or prevents adverse toxicities (GI disturbances such as anorexia, nausea, vomiting, hematotoxicity, immunosuppression, leukopenia, thrombocytopenia, anemia and nephropathy, etc.) of many anticancer drugs. The application and mechanistic studies of SQT in future development have potential importance in basic and clinical research of the traditional Chinese therapeutic approach of "toning the blood and strengthening Qi (vital energy)" in cancer immunotherapy.

A 53-year-old woman was admitted with fever and general fatigue in December, 1988. A diagnosis of malignant histiocytosis (MH) was made based on her high level of LDH, thrombocytopenia, mild splenomegaly without systemic lymphadenopathy. There was also bone marrow infiltration large atypical cells and erythro-phagocytosis. VEPA therapy resulted in complete remission. Visual disturbance and left lagophthalmos were recognized in March 1990. These signs indicated central nervous system (CNS) relapse which disappeared after intrathecal methotrexate injection. The same symptoms and signs appeared after another, 5 months. Tumor cells were found not only in the central spinal fluid but also in bone marrow. CNS and bone marrow recurrence were treated with intrathecal methotrexate injection VEPA therapy and cranial irradiation. We diagnosed this case as MH, based on the clinical features which did not include systemic lymphadenopathy and laboratory findings although TcR-gamma rearrangement was observed in bone marrow cells. Only one case of CNS infiltration diagnosed when alive has previously been reported in Japan. We report here a very rare case in which by medical treatment CNS infiltrations was improved twice.

Fourteen children (ages 2-15 years) with acute leukemia in relapse were treated with daily recombinant interferon gamma for 14 days by subcutaneous injections at fixed dose levels of 0.1, 0.25, 0.5, or 0.75 mg/m2 (1.0, 2.5, 5.0, or 7.5 x 10(6) units/m2) without intrapatient escalation. Patients received a second 14-day course of therapy followed by thrice weekly administration unless there were signs of progressive disease or grade 3 or 4 toxicity. Side effects in the 13 evaluable patients included fever (n = 10), fatigue (9), decreased Karnofsky performance score (8), hypertriglyceridemia (8), myalgia (5), weight loss > 5% (4), elevated liver transaminases (4), and abdominal pain (3). There was only one grade 4 toxicity: one of the six patients at the 0.5 mg/m2 dose level developed reversible acute renal failure. One patient died of gastrointestinal hemorrhage due to disease-related refractory thrombocytopenia. One child had an oncolytic response and two others stable disease for 138 and 148 days. An appropriate dose level for phase II studies in children is 0.5 mg/m2 per day.

This multi-center trial was carried out to assess the therapeutic potential of recombinant tumor necrosis factor (rTNF) as the first form of systemic therapy for advanced carcinomas of gastric and pancreatic origin. To be eligible patients were required to have no overt sign of coagulopathy and hepatic function studies with enzymes less than two times beyond the normal range. Twenty nine patients with gastric cancer and 26 with pancreatic cancer were entered from various institutions in the Southwest Oncology Group with 27 and 22, respectively, meeting eligibility criteria. Drug treatment consisted of rTNF (Genentech) given at a dose of 150 micrograms intravenously for five consecutive days every 3 weeks; 50% dose reduction was made for acute intolerance such as hypotension or severe fever and chills. Although eight patients with gastric cancer and five patients with pancreatic cancer received four or more courses of treatment, no objective antitumor responses were recorded. As in other trials common toxicities of rTNF included nausea and vomiting, chills and fever, hypotension, headache, myalgias, fatigue and malaise. However, in this trial, other toxicities became prominent: four episodes of symptomatic disseminated intravascular clotting occurred among patients with pancreatic cancer. Eleven with this disease and five with gastric cancer manifested laboratory findings of abnormal amounts of fibrin split products, and/or hypofibrinogenemia, and/or thrombocytopenia after treatment began. Other laboratory abnormalities that were commonly encountered included hyperglycemia, hypertriglyceridemia, anemia, neutropenia and an elevation in liver enzymes. We conclude that rTNF does not demonstrate antitumor efficacy against adenocarcinomas of the stomach and the pancreas.(ABSTRACT TRUNCATED AT 250 WORDS)

A 50-year-old man complained of lumbar pains, lack of energy, dysarthria and ataxic gait. Investigation revealed progressive anaemia (haemoglobin initially 10.5 g/dl, later 6.8 g/dl) and thrombocytopenia (initially 67,000/microliters, later 25,000/microliters). In addition he had unexplained pyrexia of up to 39.8 degrees C. Lactate dehydrogenase was 780 U/l and fragmented red cells were noted in the blood film. Because of suspicion of thrombotic thrombocytopenic purpura, treatment with fresh plasma by infusion was immediately initiated. On the third day of treatment he developed left ventricular failure; auscultation revealed a blowing early diastolic murmur over Erb's point together with a spindle-shaped early diastolic murmur over the right second intercostal space. Computed tomography of the skull showed recent haemorrhage into the left half of the cerebellum and an older right posterior infarct. The abdominal ultrasound scan suggested a haemorrhagic spleen infarct. In view of these findings the diagnosis was revised to embolizing aortic endocarditis with aortic reflux (confirmed by colour Doppler echo-cardiography). Aortic valve replacement was performed immediately, and the patient was treated with gentamycin 80 mg/d and teicoplanin 400 mg/d for four weeks. Postoperatively he was given 12 units of platelet concentrate and the platelet count remained stable thereafter (greater than 100,000/microliters). Splenectomy became necessary because the splenic haematoma increased in size during oral anticoagulant therapy. After a 6 week hospital stay the patient was discharged in good condition.

The application of recombinant DNA technology to the production of tumor necrosis factor has resulted in the availability of large quantities of a highly purified protein product. This product has been evaluated extensively in preclinical studies, which have documented a direct cytostatic and cytotoxic effect on human tumor cells, as well as a variety of immunomodulatory effects on various immune effector cells, including neutrophils, macrophages, and T cells. In addition, a number of anti-infective and metabolic effects have been documented. In addition to its in vitro effects, rTNF has been shown to have antitumor activity in vivo in preclinical studies involving both transplantable murine tumors and human tumor xenografts. Such observations have led to the evaluation of rTNF as a potential antineoplastic agent in humans. Both single- and multiple-dose phase I studies have confirmed that rTNF can be safely administered to patients with advanced malignancies in a dose range associated with anticancer effect without concomitant serious toxicities such as shock and cachexia. The most commonly observed clinical toxicities include constitutional symptoms, such as fever, chills, headache, and fatigue, and toxicities, which can be at least partially controlled with concomitant administration of nonsteroidal anti-inflammatory drugs, such as acetaminophen and meperidine. Hypotension, which occurs at high doses administered by short intravenous infusion, can usually be prevented by prehydration with intravenous fluids or otherwise controlled by the administration. An intense local inflammatory reaction at the injection site as well as thrombocytopenia appear to be the dose-limiting toxicities after subcutaneous and intramuscular administration. Neurologic toxicity is infrequent, except following continuous intravenous infusion, where it may manifest as transient focal neurologic deficits or seizure. Prolonged administration of rTNF at higher doses may be associated with transient, subclinical decreases in diffusing capacity. Patients with underlying cardiopulmonary disease should be excluded from rTNF therapy in future clinical studies until the end-organ toxicities of this agent are better defined. For at least one preparation of rTNF there appears to be no evidence for the formation of antibodies to rTNF in patients who receive multiple administrations of the agent. Pharmacokinetic studies have shown a relatively rapid clearance following intravenous infusion with a half-life of 15 to 30 min and dose-dependent pharmacokinetics. rTNF can be detected in the serum following intramuscular or subcutaneous injection at only relatively high doses, suggesting a decreased bioavailability with the routes of administration. Early phase I studies defined tolerable dose ranges for each route of administration and began to explore immunomodulatory and metabolic effects of rTNF.(ABSTRACT TRUNCATED AT 400 WORDS)

Based on recent preclinical data suggesting synergism between 5-fluorouracil (5-FU) and interferon alpha (IFN-alpha) and clinical activity of the combination therapy in colon cancer, 14 patients with advanced gastric cancer were treated with combination therapy of 5-FU and recombinant interferon alpha-2b (rIFN alpha-2b) (Intron A, Schering, Kenilworth, NJ, U.S.A.). The maximum tolerated dose was 5-FU 750 mg/m2/day given as a continuous infusion daily for 5 days followed by weekly bolus injection of the same initial daily dose, plus rIFN alpha-2b 5 X 10(6) U given subcutaneously 3 times weekly starting day 1 of 5-FU infusion. The dose-limiting toxicities were fatigue/weakness, diarrhea, and neurologic toxicities such as somnolence and confusion. The other common side effects were nausea, fever, leukocytopenia, thrombocytopenia, and the darkening of the skin. Of 13 evaluable patients, 4 had a partial response (duration 6, 14, 24, and 28 weeks). These data suggest that combination therapy of 5-FU plus rIFN alpha-2b is tolerable and has manageable side effects in patients with advanced gastric cancer. Further Phase II study will be needed to define the antitumor activity of this combination.
