Twenty-three children with advanced cancer refractory to conventional therapy received weekly iv doses of neocarzinostatin for 5 weeks. Doses were escalated from 500 to 6750 units/m2/week. Four types of toxic manifestations occurred: acute reactions consisting of shaking chills with or without fever and cyanosis (rigor), hypersensitivity, vomiting, and marrow depression. Evidence of oncolytic activity was limited to patients with acute leukemia in whom phase II trials at doses between 3000 and 4500 units/m2 appear warranted.

Ftorafur is a 5-fluorouracil analogue which is slowly metabolized to 5-FU, resulting in prolonged therapeutic levels of this latter drug. Ninety-one evaluable patients with metastatic breast cancer were treated with Ftorafur, Adriamycin, cyclophosphamide, and BCG (ACFTOR-BCG), in an attempt to increase the effectiveness of the program or decrease its myelosuppressive toxicity. The results of this trial were compared to those previously reported with the combination of 5-FU, Adriamycin, cyclophosphamide, and BCG (FAC-BCG). Overall objective response rates were 65% and 76% for ACFTOR-BCG and FAC-BCG, respectively. Durations of response were 12 months and 14 months for ACFTOR-BCG and FAC-BCG (p = 0.53). The median survival of responders was 22 and 23.9 months, respectively. Substantial toxicity was observed with Ftorafur: nausea and vomiting severe enough to cause weight loss was observed in a substantially higher fraction of the patients treated with this drug than with 5-FU. Other side-effects, which were not observed with the 5-FU combination, were somnolence, dizziness, personality changes, tremor, ataxia, and confusion. No differences in myelosuppressive toxicity were observed between the two combinations, and the incidence of infectious complications was identical. The combination of Ftorafur, Adriamycin, cyclophosphamide and BCG did not offer any advantages with respect to increased effectiveness or reduced toxicity over the FAC-BCG regimen in breast carcinoma.

A good tumoricidal activity of vindesine (VDS) has been reported in a variety of animal tumors and in human leukemias and lymphomas. We treated 22 patients who had received no prior chemotherapy and were suffering from a variety of malignant neoplasms with 0.5 mg/m2 to 3.0 mg/m2 VDS i. v. once or three times at weekly intervals and recorded the clinical, hematologic, and especially, neurological side effects. Clinically we observed fatigue in nine patients, paresthesias in seven, myalgias in three, vertigo and diarrhea in two, and skin pains, tinnitus, gastric pains, alopecia, and tremor in one patient each. There was no obvious dose-action relationship. Paravenous injection caused cellulitis similar to that seen with vincristine. No side effects were apparent in liver (SGPT) and renal (creatinine) function tests. Hematologically there was a clear trend toward leukopenia with higher doses of DVA and a mean increase in the thrombocyte count by 51 X 10(3)/mm3 was found (sign test: P greater than 0.05). The hemoglobin level did not change. Clinical neurological examination and monitoring by electroneurography revealed no changes in tensiometer performance, motor and sensory nerve conduction velocity, motor or sensory nerve action potential amplitudes, or H-reflex responses. There was dose-related diminution of the proprioceptive reflexes, especially in the lower extremities. Even with as little as 2.0 mg/m2 VDS i. v. at weekly intervals for 3 weeks Achilles and patellar tendon reflexes were diminished or absent in all patients.

Inbred Swiss mice were treated with technical DDT (1) orally with the diet or by intubation; (2) subcutaneously and (3) by skin painting. The total duration of the experiment was 80 weeks. There was no difference in body growth and mortality between the experimental and control groups. Toxic manifestations of DDT were observed in treated mice in the form of tremor, convulsions and corneal opacity usually after 40 weeks. Oral and subcutaneous DDT treatment resulted in a significant increase in the incidence of tumours mainly of lymphoid tissues, lung and liver. The highest tumour incidence was recorded in the group of mice receiving DDT by subcutaneous injections. Males and females were equally susceptible. No evidence of carcinogenicity was observed in the painted group.

Cell detachment from and around Walker 256 tumors grown in rats is quantitated by a standardized in vitro shaking procedure. The volume of cells detached from cancers of similar size is virtually the same in tumors growing in the liver, the spleen, in intramuscular and in subcutaneous sites. In cystic tumors, greater volumes are detached from the innermost regions of the walls adjacent to necrotic material than from the outermost parts. More liver perenchymal cells are shaken free of liver adjacent to a tumor interface than from regions 0.5 and 1.0 cm distant from it. Detachment of tumor and liver cells is also enhanced by prior incubation of tissue samples with necrotic extracts. It is suggested that the necrotic regions of tumors, and products derived from them, facilitate the detachment of tumor cells and cells composing the normal tissues surrounding them, thereby potentially promoting metastasis and invasion.

Conditions for optimal immunization of allogeneic lymphocytes against human tumor cells were studied. Maximal cell-mediated cytotoxic responses were generated usually with 2-4 X 10(4) tumor cells and 1 X 10(6) lymphocytes after a 5-day incubation. A further increase in the number of stimulating cells usually suppressed the immunization of lymphocytes. Viable untreated tumor cells were generally more immunogenic than were the mitomycin C-treated tumor cells. Lymphocytes (1 X )0(6)) sensitized in small volumes (0.5-1 ml) of medium were invariably transformed into cytotoxic effector cells, whereas the same number of lymphocytes sensitized in relatively larger volumes (4 ml) of medium had little or no cytotoxic activity. Occasional shaking of mixed culture during the sensitization provided better immunization than that in similar stationary culture. The replacement of culture fluids with fresh medium during incubation decreased the cytotoxicity level of sensitized cells.

Muramyl tripeptide phosphatidylethanolamine (MTP-PE; CGP 19835A from Ciba Geigy) is a synthetic muramyl tripeptide structurally related to bacterial cell wall constituents. MTP-PE activates monocytes in vitro to a tumoricidal state and has in vivo antitumor effects in animal models. We studied the toxicity and immunomodulatory effects of once weekly i.v. administration of liposomal-encapsulated MTP-PE for 8 weeks in 27 patients with advanced malignancies. Doses ranged from 0.1 to 2.7 mg/m2. No major tumor responses were seen; 11 patients had stable disease after 8 weeks of therapy and 3 continued on maintenance therapy because of minor tumor regressions and/or clinical improvement. MTP-PE at these doses was well tolerated. Shaking chills and fevers were the most common toxicities and occurred at all dose levels. There was no treatment-induced loss of performance status. Immunomodulatory studies revealed evidence of a biological effect on monocytes. C-reactive protein levels rose in the majority of patients with end-of-treatment values 2 to 10 times higher than baseline. Serum neopterin levels were consistently increased 24 h after MTP-PE administration and significant decreases in expression of two different types of Fc receptors on peripheral blood monocytes were noted 6 h after treatment. Although no major tumor responses were seen in this group of patients with advanced malignancies, MTP-PE was well tolerated and exerted biological effects on monocytes. Serum neopterin levels may be a useful marker for the biological effects of MTP-PE.

Besides general complications of immunosuppression such as increased susceptibility to opportunistic infections or malignancy, individual immunosuppressive agents are associated with specific side effects. Nephrotoxicity is the major side effect of cyclosporine (CsA). Various attempts have been made to minimize this toxicity, such as monitoring drug blood levels, modifying the protocol, and coadministering other agents. Other side effects caused by CsA are hepatotoxicity, hyperkalemia, hypertension, tremor, gum overgrowth, and hirsutism. Azathioprine (AZA) causes dose-related bone marrow suppression, commonly leading to leukopenia. Careful monitoring of complete blood cell count and dosage adjustment according to white blood cell count are usually adequate to prevent serious leukopenia. The side effects of corticosteroids are numerous and include slow wound healing and de novo insulin-dependent diabetes mellitus. Many complications are dose related, and with low dosage or discontinuation of steroids, their frequency rapidly decreases. Antilymphoblast and antithymocyte globulins (P-ALG) are foreign antibodies and may cause allergic-type reactions such as fever, chill, and hypotension. The initial side effect of monoclonal antibody (muromonab-CD3, OKT3) is similar to that of P-ALG. It includes high fever, shaking chills, headache, rigors, and hypotension. To prevent it, acetaminophen, an antihistamine, and a steroid usually are administered before injection. Because this agent is also associated with high frequency of pulmonary edema, it should not be given to any patient who has more than 3% body weight gain during the week prior to therapy. In rare case, it causes aseptic meningitis or encephalopathy, which is manifested by fever, severe headache, and seizure.

Trimetrexate is a nonclassical antifol currently being tested for efficacy in cancer patients and as an antiparasitic agent against Pneumocystis carinii pneumonia in AIDS patients. We have now received the first reports of hypersensitivity reactions in Phase II cancer trials. Two types of reactions were noted. The most severe reaction, immediate hypotension with loss of consciousness, occurred in only one patient. Four other patients exhibited an immediate systemic effect with one or more of the following symptoms: facial flushing, fever, shaking, pruritus, bronchospasm, periorbital edema, and difficulty in swallowing. Immediate hypersensitivity should now be considered a known side effect of trimetrexate therapy, occurring in less than 2% of patients.

Interleukin (IL)-2 therapy leads to respiratory dysfunction due to increased vascular permeability. This study examines the role of the chemoattractant, immunomodulator, and permeability-promoting agent leukotriene (LT) B4 in this setting. Sheep with chronic lung lymph fistulae were given IL-2, 10(5) U/kg as an IV bolus (n = 6). Within 2 hours this led to a significant increase in LTB4 levels in both plasma and lung lymph. The mean pulmonary artery pressure (MPAP) rose while the pulmonary artery wedge pressure was unchanged. Arterial oxygen tension (PaO2) fell. Lung lymph flow (QL) was tripled (P less than 0.05) at 3 hours, coinciding with an increase in the lymph/plasma (L/P) protein ratio (P less than 0.05) resulting in an increase in the lymph protein clearance (P less than 0.05), data documenting increased microvascular permeability to protein. Mild leukopenia and thrombocytopenia (P less than 0.05) occurred. Body temperature rose and shaking chills were common. Pretreatment with the lipoxygenase inhibitor diethylcarbamazine (DEC; n = 6) reduced baseline plasma LTB4 levels and prevented the IL-2-induced increases in LTB4 in plasma and lung lymph (P less than 0.05). In contrast to IL-2 treatment alone, DEC blunted the increase in MPAP and prevented the rises in QL (P less than 0.05), L/P protein ratio (P less than 0.05), and lymph protein clearance (P less than 0.05). DEC also prevented the IL-2-induced leukopenia, the fall in platelet count, and the rise in body temperature (P less than 0.05, respectively). Infusion of IL-2 excipient control (n = 5) did not affect plasma or lymph LTB4 levels but there were mild increases in MPAP (P less than 0.05). The QL also rose but this occurred while the L/P protein ratio fell (P less than 0.05). Body temperature rose moderately. The PaO2, leukocyte, and platelet counts were unaffected. These data indicate that IL-2 administration leads to pulmonary dysfunction manifest by pulmonary hypertension and increased vascular permeability, events associated with LTB4 synthesis and prevented by DEC. Leukotriene B4 appears therefore to mediate the IL-2-induced lung injury.
