Phase I trial of N-methylformamide (NMF, NSC 3051).
N-methylformamide (NMF) is a polar-planar solvent with both cytotoxic and differentiating activity in preclinical models; it also acts as a radiosensitizer. We treated 17 patients with 18 courses of NMF on a schedule of six weekly doses, administered on a rapid intravenous infusion, which were escalated from 875 to 2,000 mg/m2/wk. The predominant toxicity was a dose-related syndrome of fatigue, malaise, nausea, and anorexia, which was reflected by a decrease in performance status (Karnofsky) of greater than or equal to 20% in six of ten patients who received doses greater than or equal to 1,500 mg/m2/wk. Other gastrointestinal toxicities included moderate vomiting and mild diarrhea. Reversible increase of liver enzymes occurred in six of ten patients at doses greater than or equal to 1,500 mg/m2/wk. The maximum tolerated dose on this schedule is 1,500 mg/m2/wk; the dose recommended for phase II studies is 1,125 mg/m2/wk. Future studies of this regimen in a combined modality setting are planned.

Prospective validation of a pharmacologically based dosing scheme for the cis-diamminedichloroplatinum(II) analogue diamminecyclobutanedicarboxylatoplatinum.
We previously correlated both renal function and thrombocytopenia, the dose limiting toxicity of carboplatin, with the plasma pharmacokinetics of carboplatin. From these correlations, we developed equations to calculate carboplatin dosage for any patient based on that patient's creatinine clearance, body surface area, pretreatment platelet count, desired platelet nadir, and status of prior chemotherapy. We prospectively applied these equations in 44 courses of carboplatin given to 24 patients. There were 13 males and 11 females with median age 53 (range, 33-77), median Karnofsky performance status 80 (range, 50-100), and creatinine clearance 32 to 118 ml/min. Ten patients had creatinine clearances less than 60 ml/min. Precision of the equations used for dose calculation was evaluable in 38 courses administered to 23 patients. In 23 courses of carboplatin administered to 12 patients without extensive prior chemotherapy, the observed change in platelets = 1.04 X predicted change -48,000 (r = 0.96). In the 15 courses of carboplatin administered to 11 heavily pretreated patients, the observed change in platelets = 1.13 X predicted change +6,600 (r = 0.97). For the overall combined population, the observed change in platelets = 0.96 X predicted change -7,000 (r = 0.94). These relationships which nearly define the line of identity (observed = expected) validate our initial observations. Only 2 patients developed WBC less than 2,000, but 12 patients developed hematocrit less than or equal to 29% and 8 required RBC transfusions. Fifteen patients had nausea and vomiting greater than or equal to grade 2. There were no other nonhematological toxicities observed. In view of continuing documentation of the antitumor activity of carboplatin, these equations allow safe and rational drug dosing of patients with potentially platinum-responsive tumors but with renal function too poor to receive cisplatin. Among the 9 patients in this study evaluable for response, there was 1 partial response in a patient with malignant melanoma and 1 objective response (less than partial response) in a patient with adenocarcinoma of the cervix.

Mesothelioma following Wilms' tumor in childhood.
A high percentage of children with Wilms' tumor are cured with multimodal treatment. A small percentage of these children will develop second tumors, perhaps related to a genetic predisposition to neoplasia or possibly secondary to the treatment utilized for Wilms' tumor. Malignant mesothelioma has been associated with contact with asbestos but has also been reported after radiation exposure. Two patients are reported who developed malignant mesothelioma of the pleura after treatment for Wilms' tumor in childhood. Both received orthovoltage radiation; one patient also received triethylenemelamine (TEM), an alkylating agent closely related to nitrogen mustard, for 5 years. Factors in the development of second tumors are discussed.

Doxorubicin, cyclophosphamide, and whole body hyperthermia for treatment of advanced soft tissue sarcoma.
Eleven patients with advanced soft tissue sarcoma were treated with whole body hyperthermia (41.8 degrees C-43.0 degrees C) for 2 hours, doxorubicin (45 mg/m2) at the beginning of peak temperature and cyclophosphamide (1000 mg/m2) 6 hours after doxorubicin. Warming was accomplished with a nylon and vinyl mesh water perfused suit and heating blankets under barbiturate anesthesia. Thirty-five thermochemotherapy treatments were administered after an initial baseline euthermic course. There were two complete and two partial responses including three of three liposarcomas and one of two leiomyosarcomas, and there were two disease stabilizations . Morbidity included anasarca, nausea and vomiting, diarrhea, myalgias, mild surface burns, perioral herpes simplex, reversible neuropathy, hypotension, and cardiac arrythmias . Hyperglycemia and hypophosphatemia were found during heating, and normalized at 24 hours. Liver enzyme elevations occurred 24 hours after heating and normalized within 1 week. A uniform platelet decrease (mean, 107,000/microliter) was found at 24 hours. Thermochemotherapy was found to be a feasible approach for selected patients with advanced soft tissue sarcoma for the subset of liposarcomas and leiomyosarcomas.

Incidence of thrombocytopenia and serious hemorrhage among patients with solid tumors.
To evaluate the incidence of thrombocytopenia and bleeding among patients with solid tumors treated intensively with chemotherapy, the records of 1274 patients treated between 1972 and 1980 on protocols known to produce significant myelosuppression were reviewed. Three hundred one patients with solid tumors (breast, lung, melanoma, sarcoma, primary brain, testicular, hypernephroma and others) experienced 5063 days of thrombocytopenia (platelet count less than 50,000/microliters) and 670 days of severe thrombocytopenia (platelet count less than 20,000/microliters). The median number of days thrombocytopenia was 6 (range, 1-250). There were only 44 episodes of clinically detectable serious bleeding, primarily gastrointestinal (26/44), during thrombocytopenia and all but seven episodes first occurred at platelet counts between 20,000-50,000/microliters. Fifteen of the 44 bleeding episodes were associated with coagulation abnormalities, 24 occurred during serious infection, and 12 occurred at sites of tumors. One hundred forty-seven of the 301 patients (49%) received platelet transfusions. In 86 thrombocytopenic patients with central nervous system (CNS) tumors, there was no evidence of CNS bleeding during thrombocytopenia. Hemorrhagic deaths were uncommon, and of the 12 patients who died of bleeding, 7 had normal counts. There is a very low incidence of significant thrombocytopenia or bleeding among patients with solid tumors treated with combination chemotherapy or experimental agents escalated to maximally tolerated doses. These data suggest that with respect to thrombocytopenic bleeding intensive treatment of patients with solid tumors can be pursued with relative safety utilizing the standard transfusion supportive measures now widely available.

A comparison of intermittent vs. continuous and of adriamycin vs. methotrexate 5-drug chemotherapy for advanced breast cancer. A Cancer and Leukemia Group B study.
The therapeutic effectiveness of intermittent vs. continuous combination chemotherapy and of the substitution of adriamycin for methotrexate in a 5-drug regimen was evaluated in women with metastatic breast carcinoma. Patients were randomly allocated to receive continuous therapy with cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, prednisone ( CMFVP -C, 86 patients), intermittent CMFVP ( CMFVP -I, 109 patients), or intermittent CAFVP (107 patients). The CR + PR rate with CAFVP (71%) was superior to CMFVP -C (50%, p = 0.003) and to CMFVP -I (50%, p = 0.002). The remission duration with CAFVP (14 months, median) was superior to CMFVP -I (7 months) (p less than 0.01), and tended to be superior to CMFVP -C (9 months) (p = 0.07). There was a survival advantage of CAFVP (19 months, median) over CMFVP -I (13 months) (p = 0.01), but not over CMFVP -C (16 months) (p = 0.24). Among CR + PR patients, the survival with CAFVP (29 months, median) was superior (p = 0.02) to both CMFVP -I (18 months) and CMFVP -C (21 months). The CMFVP -C regimen was associated with the highest incidence of leukopenia and neurologic toxicity, but the lowest incidence of GI toxicity. The results indicate that the CAFVP regimen is well tolerated and is superior to the CMFVP regimens.

Computed tomography of the chest in small cell lung cancer: potential new prognostic signs.
Computed tomography (CT) of the chest was performed as part of the initial and subsequent staging evaluations in 33 patients with small cell lung carcinoma. In 25 of the 33 patients, CT demonstrated findings not observed on standard radiography. Eleven of the 33 would have been staged higher using CT. Before treatment, CT revealed more mediastinal and nodal involvement than conventional films. After chemotherapy, CT demonstrated areas of residual or early recurrent disease in nine of 28 patients that were not apparent on chest films. Initially thickened pericardium in patients with limited disease and persistent bronchial narrowing after chemotherapy were demonstrated to be associated with early relapse in the chest and short survival. These initial data suggest that the CT scan, in addition to more accurately assessing the extent of disease, can provide a new risk classification for early chest relapse. Initial thickened pericardium in limited disease and continued bronchial narrowing after chemotherapy may allow patient selection for future treatment trials with radiation as an adjuvant to chemotherapy.

Multiple sequential biomarkers in monitoring patients with carcinoma of the lung.
To correlate serial biomarkers and disease activity in carcinoma of the lung, carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), adrenocorticotropic hormone (ACTH), C3-derived protein (C3DP-C), and LDH were assayed in 43 patients with small cell lung carcinoma (SCLC) and in 20 patients with non-small cell lung cancer (NSCLC) (15 with adenocarcinoma, three with squamous cell carcinoma, and two with mixed histology). Disease status after treatment was rated as one of the following: complete response, partial response, minor regression, stable disease, and progressive disease. Significant correlations between disease status and markers in SCLC were found for CEA, NSE, LDH, and ACTH. In NSCLC, only CEA and LDH showed significant correlation. Marker-marker correlations were significant in SCLC for CEA and NSE (P less than 0.05), CEA and LDH (P = 0.01), and NSE and LDH (P less than 0.01); in NSCLC none were significant. None of the markers exhibited significant correlations with specific metastatic sites. Certain biomarkers (CEA, NSE, and LDH in SCLC; CEA and LDH in NSCLC) can be used alone or in combination to monitor disease activity but appear to be no more sensitive than standard clinical investigational methods.

Phase I clinical and pharmacologic trial of carboplatin daily for 5 days.
Twenty-two patients with refractory tumors received 64 courses of iv bolus carboplatin every day X 5, every 4-5 weeks. All patients are evaluable for toxicity and 18 are evaluable for response. For solid tumor phase II studies, a dose of 77 mg/m2/day X 5 is recommended for patients who have received prior chemotherapy. Patients with no prior chemotherapy experience should receive 99 mg/m2/day X 5. The major dose-limiting side effect is dose-related thrombocytopenia. Courses of carboplatin on this schedule should be repeated every 5 weeks to avoid cumulative wbc count toxicity, since leukopenia frequently did not occur until Day 28. Other toxic effects observed were nausea and vomiting and lower-extremity myalgias and arthralgias. There was no evidence of hearing loss, mucosal damage, or changes in liver or renal function tests of any patient while in this study. Therapeutic responses were seen in four patients: one partial response in renal cancer of 9+ months' duration; one partial response in head and neck cancer of 7+ months' duration; and objective responses in melanoma and colorectal carcinoma of 6 months' duration.

Pharmacokinetics and dosage reduction of cis-diammine(1,1-cyclobutanedicarboxylato)platinum in patients with impaired renal function.
cis-Diammine(1,1-cyclobutanedicarboxylato)platinum (CBDCA) is a nonnephrotoxic but myelosuppressive analogue of cisplatin (DDP) with greatly reduced protein binding and greatly increased renal excretion. Thus, CBDCA might produce undue toxicity in patients with decreased renal function. Twenty-two patients [14 females and 8 males; median age, 66 (range, 35 to 83); median Karnofsky performance status, 70 (range, 40 to 90)] with refractory tumors and renal dysfunction [creatinine clearance (CCr) 6 to 83 ml/min] were treated with 31 courses of i.v. bolus CBDCA every 4 to 5 weeks. Dosages were determined by pretreatment CCr. Patients with CCr greater than or equal to 40 ml/min received 400 mg/sq m; patients with CCr 20 to 39 ml/min received 250 mg/sq m; and patients with CCr 0 to 19 ml/min received 150 mg/sq m. Toxicities were assessed by weekly clinical and laboratory assessment. Responses were assessed in patients with measurable disease. Plasma pharmacokinetics and urinary excretion of total and ultrafilterable platinum were measured with flameless atomic absorption spectrometry. Observed toxicities were similar to those in patients with normal renal function. Myelosuppression, especially thrombocytopenia, was the major toxicity. Nausea and vomiting were mild to moderate. There was no ototoxicity, neurotoxicity, or nephrotoxicity or reduction in CCr due to CBDCA. Total body clearance of ultrafilterable platinum correlated highly with CCr. The percentage of reduction in platelet count correlated highly and linearly with the area under the curve (AUC) of plasma-ultrafilterable platinum. However, for any AUC, there was 17% greater platelet reduction in patients who had previously received extensive myelosuppressive chemotherapy than in nonpretreated patients. Since total body clearance is proportional to CCr, platelet reduction is proportional to AUC, and total body clearance = dosage/AUC, we have derived an equation to calculate a dosage that will produce a desired reduction in platelet count. Calculations for theoretical patients (both pretreated and nonpretreated) with CCr of 100 ml/min produce dosages very close to maximum tolerated dosages derived in actual Phase I trials. The actual clinical utility of these predictive equations must await validation in prospective studies with larger numbers of patients.

High-dose intravenous gammaglobulin in alloimmunized platelet transfusion recipients.
High-dose intravenous gammaglobulin (polyvalent immunoglobulin G) has been shown to be of benefit in some patients with immune thrombocytopenic purpura (ITP), possibly by producing reticuloendothelial system blockade. We studied this approach in patients refractory to random donor platelet transfusion using an IV IgG preparation manufactured by the Swiss Red Cross. Eleven adult patients with acute leukemia received either 0.4 g IgG/kg/d intravenously X five days (four patients) or 0.6 g/kg/d X five days (seven patients). All patients had high levels of lymphocytotoxic antibody and poor responses to random donor platelets. Except for mild headaches in two patients, there were no side effects related to the IgG infusions. All patients had significant elevations of serum IgG on the day after completion of treatment. Either random donor or partially HLA-matched platelet transfusions were administered the day after and, in some cases, during the IgG therapy. No patient had an improvement in one hour posttransfusion platelet count increments. Two additional patients received pooled platelet concentrates incubated for 30 minutes at 37 degrees C with IgG at a final concentration of 3 g% prior to transfusions. These results indicate that high-dose IgG, an extremely expensive treatment, cannot be recommended for alloimmunized adults with leukemia.

The ineffectiveness of random donor platelet transfusion in splenectomized, alloimmunized recipients.
The effect of splenectomy on the response to random donor platelet transfusion in 15 multitransfused thrombocytopenic patients is presented. Eight patients responded poorly, with low corrected platelet count increments at 1 and 24 hours posttransfusion. These eight patients were clinically alloimmunized and had lymphocytotoxic antibody ( LCTAb ) in their sera. They responded well to closely HLA-matched transfusions. In contrast, seven splenectomized patients responded well to random donor platelets. Five of these patients had no LCTAb and no other evidence of immunization. Two patients who responded well to random donor platelets had "weak" LCTAb , and one responded to platelets presplenectomy in the presence of this antibody. Splenectomy does not improve the response to random donor platelets in alloimmunized recipients.

Lymphocytotoxic antibody is a predictor of response to random donor platelet transfusion.
The transfusion records of 189 patients with acute leukemia were analyzed to correlate lymphocytotoxic antibody (LCTAb) levels with response to a series of random-donor platelet transfusions (Tx). Twenty-one patients were studied twice at times of different LCTAb levels. All transfusions were given when patients were clinically stable without disseminated intravascular coagulation, bleeding, temperature greater than 101 degrees F, or splenomegaly. The mean 1-hr and 24-hr corrected count increments (CCI) for all patients with negative LCTAb were 16,100 and 12,000, and values for patients with positive LCTAb were 5,600 and 2,600 (P less than 0.0005). Thirteen patients had intermediate LCTAb (10-20%) and a variable response to Tx. Of the 137 patients with negative LCTAb levels 106 (77%) had good mean CCI of greater than 10,000 at 1 hr and greater than 7,500 at 24 hr following transfusion. In contrast of 60 patients with positive LCTAb (greater than 20% cytotoxicity), 53 (88%) had poor CCI of less than 10,000 at 1 hr and less than 7,500 at 24 hr after transfusion. Only 4 patients with positive LCTAb had a good response to random donor platelets at both 1 and 24 hrs. Eighteen patients had negative LCTAb with a high 1-hr and low 24-hr CCI. Thirteen of these had a history of positive LCTAb and in 9 there was an anamnestic rise following transfusion. Nine of 137 patients had negative LCTAb with low 1-hr and 24-hr CCI. LCTAb is highly predictive of response to random donor platelets. Cytotoxicity to greater than 20% of tested lymphocytes virtually precludes a good CCI at 1 and 24 hr.

Sustained post-transfusion granulocyte count increments following transfusion of leukocytes obtained from donors with chronic myelogenous leukemia.
Leukocyte transfusions from patients with chronic myelogenous leukemia (CML) and elevated WBC counts were given to 14 patients with acute leukemia for the treatment of 16 infectious episodes. The WBCs were not irradiated to determine if engraftment with production of granulocytes would occur following infusion of immature myeloid elements. No recipient was alloimmunized by clinical and serologic criteria. High leukocyte yields were obtained using a variety of differential centrifugation techniques with a mean WBC yield/transfusion of 95 X 10(9) (range 19-275). A mean of 2.5 transfusions (range 1-11) were administered/recipient with a mean total dose of 235 X 10(9) WBC/transfusion episode (range 50-590). Seven patients had granulocyte counts greater than 500/microliters for four or more days (range 4-11 days) following the last transfusion. Ph1 chromosomes were documented in 2 of 4 patients tested 2-8 days following transfusion. Leukocyte alkaline phosphatase scores were increased (greater than 150) in 5/5 recipients tested post-transfusion demonstrating that production of this enzyme can be induced in CML granulocytes. Except for one severe transfusion reaction, there were no significant side effects and no recipient developed signs of graft versus host disease. All patients with sustained increments demonstrated rapid clinical improvement including 3 severely infected, poor risk patients undergoing initial induction therapy. These 3 patients all achieved complete remission with no evidence of the Ph1 chromosome. Because of the high dose of WBC which can be collected and the salutary effect of continued leukocyte production, CML WBC may be the preparation of choice for selected, non-alloimmunized, severely infected patients.

Renal failure and platinum pharmacokinetics in three patients treated with cis-diamminedichloroplatinum(II) and whole-body hyperthermia.
Three patients with advanced refractory malignancies were treated with whole-body hyperthermia (WBH: 42-42.3 degrees C) for 2 h during which time they also received an infusion of 60 or 80 mg/m2 of cis-diamminedichloroplatinum II (DDP). Each patient developed an elevated serum creatinine (2.7-13.6 mg/dl), with maximum creatinine occurring between days 7 and 12 after treatment. WBH did not alter plasma or urinary pharmacokinetics of total or ultrafilterable platinum compared with pharmacokinetic data of the same or other patients given DDP euthermically. Although the mechanism of the renal damage is unclear, it appears that WBH can potentiate the nephrotoxic actions of DDP and that further study of this combination is not warranted.

Therapeutic efficacy and pharmacokinetics of vindesine and vindesine-cisplatin in previously treated patients with non-small cell lung carcinoma.
Twenty-nine patients with non-small cell lung cancer refractory to prior therapy were treated with either vindesine (VDS) alone (3 mg/m2 every week) or the combination of VDS plus cisplatin (DDP) (100 mg/m2 every 28 days). Serial blood and urine samples were collected to assess the pharmacokinetics of VDS and DDP. All patients were evaluable for toxicity and 27 were evaluable for response. No objective antitumor responses were observed. Peripheral neuropathy manifested by paresthesias, muscle weakness, and constipation were observed in 20 treated patients, and hematologic toxicity consisting of thrombocytopenia and/or leukopenia occurred in 18 patients. The plasma and urinary pharmacokinetics of VDS and DDP measured in this study indicate that VDS and DDP do not interfere with each other and that the pharmacokinetics in previously treated and untreated patients are similar. The antitumor responses and degree of toxicity observed in this trial compare unfavorably with previously reported VDS and VDS-DDP trials in previously untreated patients with this disease and suggest that prior exposure to chemotherapy might both decrease antitumor activity and enhance toxicity of these chemotherapeutic agents.

Acquired toxoplasmic lymphadenitis with demonstration of the cyst form.
Acquired toxoplasmosis usually is diagnosed serologically. Specific histologic criteria allow for the recognition of this disease in lymph node sections. However, Toxoplasma cysts are rarely seen in nodes. The lymph node from a 15-year-old male with asymptomatic lymphadenopathy was found to have typical histologic features of toxoplasmic lymphadenitis. Toxoplasma cysts were identified and specific serology was confirmatory.
