Effects of high activities of I 131 meta-iodobenzylguanidine (mIBG) were evaluated in nine children with advanced neuroblastoma. All patients had been previously heavily treated and had either primarily refractory disease or resistant relapse. Twenty-two doses of mIBG labeled with 1.3 to 4 GBq (35-108 mCi) of iodine 131 were administered. Three subjective effects, especially relief of pain, and two objective effects were observed. Transient blood pressure increase was observed once and did not recur after prolongation of the infusion time to 6 hours. A major side effect was bone marrow toxicity, essentially marked by thrombopenia, particularly severe in previously bone-marrow-transplanted patients.

A phase I study of the intracarotid administration of PCNU was conducted in patients with intracerebral tumors recurring after cranial radiation. Seventeen patients were treated including 16 with recurrent gliomas or glioblastomas and 1 with recurrent brain metastases from adenocarcinoma of the lung. An additional patient received a vertebral artery infusion of PCNU for a recurrent glioblastoma. Seven of 17 patients receiving intracarotid PCNU responded for a response rate of 41%. If only evaluable patients with gliomas are considered, the response rate was 44%. Tumor grade at time of initial diagnosis, exposure to prior chemotherapy, and dose of PCNU did not appear to have a major impact on response rate. Zubrod performance status 3 patients had a lower response rate (25%) than did patients with performance status 1 or 2 (response rate 63%). Thrombocytopenia and reversible central nervous system toxicity were dose limiting at a PCNU dose of 110 mg/m2. Two patients had possible permanent central nervous system toxicity. Three patients had permanent ipsilateral visual impairment, including one at the lowest dose used into the carotid artery (60 mg/m2). Orbital pain appeared to be substantially less than that seen with intracarotid BCNU but headaches may have been somewhat more common. The single patient receiving a vertebral artery infusion developed marked headaches and restlessness after receiving 25 mg/m2 of a planned 75 mg/m2 treatment into the vertebral artery and the treatment had to be discontinued. Symptoms were rapidly reversible upon stopping the medication. Our overall impression is that intracarotid PCNU causes less ocular pain but more transient central nervous system toxicity than does intracarotid BCNU.(ABSTRACT TRUNCATED AT 250 WORDS)

Tiazofurin is a novel C-nucleoside with significant antitumor activity in murine tumor models. In a phase I clinical trial, patients received tiazofurin by bolus iv infusion daily for 5 days. Six doses ranging from 550 to 4100 mg/m2/day were evaluated. Thirty-one treatment courses were initiated in 21 patients. Tiazofurin induced multiple, transient toxic effects at all but the lowest dose level, and treatment interruption was a common result. Nine of 28 treatment courses initiated at doses greater than or equal to 1100 mg/m2/day were interrupted at less than 5 days; only five of eight courses initiated at 1100 mg/m2/day were completed. Symptoms leading to treatment interruption included headache, nausea and emesis, and lethargy and malaise. Other significant, transient toxic effects included skeletal muscle injury manifest as pain, weakness, or serum biochemical abnormalities; mucocutaneous effects; and mental or mood changes. One case each of transient pericarditis and fatal cardiomyopathy occurred at the highest dose. Myelosuppression was observed but was transient and not dose limiting. In addition to leukopenia and thrombocytopenia, unexpected declines in serum hemoglobin were observed, although these were of uncertain significance. Tiazofurin induced significant increases in uric acid production which could be reversed with coadministration of allopurinol. Pharmacokinetic analysis revealed tiazofurin plasma elimination to be at least biphasic, with a beta-half-time of 4.2 hours; most of an injected dose could be recovered from the urine as unaltered compound within 24 hours. From this study we conclude that an appropriate dose for phase II trials with this schedule is less than or equal to 1000 mg/m2/day. The schedule may be a difficult one for clinical evaluation of antitumor activity, however, because of the possibility of frequent treatment interruption due to multiple systemic toxic effects.

Our data show that 1% of patients who required hospital treatment did so due to severe adverse reactions to analgesics. The most frequent adverse reaction was major gastrointestinal bleeding after aspirin, indomethacin, phenylbutazone or naproxen. Thrombocytopenia, second in frequency, was also mainly a complication of aspirin treatment, as was severe vertigo and tinnitus. Allergic reactions and leucopenia or agranulocytosis occurring in single cases only were associated with the use of pyrazolones. Patients with nephropathy were usually taking phenacetin or one of the close derivatives paracetamol or bucetin. Intensive monitoring for adverse reactions to drugs in 6,000 hospitalised patients in medical wards showed that analgesics, although frequently used, did not lead to life-threatening reactions. Gastrointestinal and neurological side effects were the most commonly observed reactions and these occurred more often after aspirin, indomethacin or pentazocine than after dipyrone or tilidine. Preliminary data of an international case-control-study on agranulocytosis and aplastic anaemia suggest that the incidence of agranulocytosis was in the order of 2 to 3 per million users of analgesics per year. Agranulocytosis occurred predominantly with pyrazolones, with a mortality of 1 to 2 per 10 million users per year. A cohort study on the treatment of colic pain in general practice showed that serious events most likely due to adverse reactions to analgesics were bronchospasm, shock fragments or shock. The incidence of these serious events was about 2 in 1,000 treated cases. The relative risk was not increased by treatment with pyrazolones, opioids or other drugs.

A phase I study of VP was undertaken using the methods of a single (40 cases; range of dose levels 30-540 mg/m2) and 5-day (41 cases; range of dose levels 40-140 mg/m2/day) intravenous administration. The dose-limiting toxicity of VP was moderate to severe leukopenia. MTD was estimated to be 540 mg/m2 for a single and 140 mg/m2/day for 5-day administration. The median days to WBC nadir from the start of therapy and to recovery from reaching the nadir were 10 and 10.5 for single, and 15 and 7 for 5-day administration, respectively. Thrombocytopenia was less frequent and less pronounced than leukopenia. Mild gastrointestinal disturbances and alopecia were frequently observed. Transient hepatic dysfunction, fever, headache, fatigue, dyspnea, hypotension, and pain along the vein were also encountered in a small number of patients. There were no cases with renal, neurologic or cardiac toxicity. Objective tumor regression was seen in one case each of IBL(CR), bladder cancer, non-Hodgkin's lymphoma and ATL (PR). The post-infusion plasma decay of VP in 4 cases given 80-120 mg/m2 by a single administration was biphasic with t1/2 alpha ranging from 0.13 to 0.39 h and t1/2 beta ranging from 3.33 to 4.85 h. No accumulation of VP was found in plasma after five repeated daily doses. Doses of 360-480 mg/m2 by single and 80-100 mg/m2/day by 5-day administration repeated every 3 to 4 weeks can therefore be recommended for phase II studies in good-risk patients.

Thirty-one patients with metastatic brain tumors (MBT) from lung cancer and ten patients with MBT from melanoma received BCNU, 100 mg/m2, every four weeks by intracarotid and/or vertebral artery infusion into each involved site. Twenty-five patients with lung cancer and all melanoma patients are currently evaluable. Twelve patients with lung cancer had complete and partial responses lasting from 1 to 14 months. Four of them with the histologic diagnosis of small cell carcinoma, one with large cell carcinoma and one with squamous cell carcinoma showed complete response. None of the patients with melanoma MBT experienced any response. All of the patients had periorbital erythralgia and/or occipital pain during the infusion. Four patients manifested mild focal seizures during the infusion or 6 to 24 hours after the treatment. Transient confusion with disorientation was observed in two patients 4 and 24 hours, respectively, after a BCNU infusion. Two patients developed reversible thrombocytopenia after the fifth course of the IA chemotherapy. Median survival of patients with MBT from lung carcinoma was 4 months, with two of them still alive at 10 and 14 months, respectively. Only one patients of the 25 with lung carcinoma died from MBT. Failure to control the primary disease resulted in the deaths of a vast majority of the patients.

Cefotaxime was used to treat infections in 2,579 patients during phase II and phase III clinical trials. This paper summarizes the adverse reactions reported to Hoechst-Roussel Pharmaceuticals (Somerville, NJ) during the treatment of these infections. Cefotaxime caused adverse reactions that are caused by all other cephalosporins, including pain at the site of injection (31.9%), thrombophlebitis (4.9%), skin rash (1.8%), thrombocytopenia (3.8%), glomerulotubular dysfunction (1.4%), diarrhea (1.2%), and superinfection (1.1%). Compared with cefazolin, cefotaxime caused pain on injection, phlebitis, and diarrhea more commonly (P less than 0.05) but caused superinfection less commonly (P less than 0.04). Since these data were obtained from many different sources by diverse methods, further controlled trials are needed to substantiate these differences. However, the adverse reactions caused by cefotaxime appear to be similar in spectrum and severity to those caused by other cephalosporins.

Extraneural metastases from malignant glioma and glioblastoma are believed to be rare. The most common sites of metastases are lung, lymph nodes, bone, and liver. We recently encountered two patients with glioblastoma multiforme who presented with pain and thrombocytopenia caused by diffuse metastasis to bone marrow. A premortem diagnosis was established in the first patient with the aid of peroxidase-antiperoxidase staining of the bone marrow biopsy specimen for glial fibrillary acidic protein, a glial-specific marker. In the second patient glial fibrillary acidic protein staining confirmed the glial nature of the primary brain tumor as well as the metastatic tumor in bone marrow. The first patient also had metastatic nodules on the pleural surface and on the fifth rib. All three metastatic foci had similar cellular morphology, suggesting selection of a population of tumor cells with extraneural metastatic potential.

A 48-year-old actively homosexual man who had undergone liver transplantation for cirrhosis secondary to hepatitis B infection six years previously presented with a syndrome of diffuse pain, cholestasis, and low-grade fever. The development of thrombocytopenia and persistent hypoprothrombinemia precluded liver biopsy. Subsequently, a skin eruption and VDRL result of 1:128 indicated that most of the findings could be explained by a diagnosis of secondary syphilis with luetic hepatitis and periostitis. This impression was confirmed by a complete response to penicillin therapy. The relation of thrombocytopenia to lues in this case remains uncertain.

Twenty-six adult patients were entered in a phase I trial of carboplatin, a new cisplatin derivative with reduced potential for nephrotoxicity. All patients had solid tumors and the median World Health Organization performance score was 2 (0-3). Twelve patients had not received prior chemotherapy. The drug was administered as a 15-minute IV infusion, without pre- or posthydration, at daily doses of 40-125 mg/m2 for five consecutive days. Antiemetics were given only if needed. Thrombocytopenia and neutropenia were dose related and dose limiting. One patient died from septic shock at the highest dose level. Nonhemolytic anemia was also encountered. Nausea and vomiting were experienced by most patients but gastrointestinal intolerance was severe in only two patients. One patient had hypercreatininemia, which was minor and rapidly reversible. Other toxic effects consisted of negligible fatigue, paresthesia, pruritus, local pain, stomatitis, headache, and alopecia. Although none of the patients achieved a partial or complete response, antitumor effect was strongly suggested in two patients with thyroid and cervix cancer, respectively. Carboplatin is an attractive candidate for phase II trials. In good-risk patients, such trials could be initiated at a daily dose of 100 mg/m2 for five consecutive days every five to six weeks.
