The pyrimidine analog, 5-azacytidine (NSC 102816), was administered by continuous intravenous infusion in Ringer's lactate in increasing doses to sets of patients with metastatic cancer to establish a dose sufficient to produce mild toxicity. Twenty-one patients (23 trials) were treated with doses of 50-200 mg/sq/m/day for 5 days every 2-4 wk.
Nausea and vomiting
were moderate and easily preventable. Doses of 100-200 mg/sq/m for 5 days every 14 days produced granulocytopenia, usually after two courses. Less toxicity was observed when courses were given every 21-28 days. Forty-five patients with previously treated and refractory
acute myeloblastic leukemia
were treated. The majority received doses of 150 mg/sq m for 5 days every 2 wk. Eleven (24%) complete remissions and four partial remissions were observed. The number of courses to achieve remission averaged three and required an average of 59 days. Nine patients with blastic crisis of chronic myeloblastic leukemia and four with refractory acute lymphoblastic leukemia failed to respond. 5-Azacytidine administered by continuous infusion is well tolerated and is an active compound in
acute myeloblastic leukemia
.

101 patients with acute leukemia in relapse were treated with 5-azacytidine according to three schedules: Regimen A--300 mg/m2(day divided intravenously at 8 hour intervals for 5 days; Regimen B--750 mg/m2 as a single iv pulse dose administered at 2 to 3 weeks intervals; and Regimen C--300 mg/m2/day by continuous infusion daily for 5 days. Twelve patients achieved a complete remission (CR) and six achieved a partial remission (PR) for an overall 18% response rate. Of 78 patients receiving an adequate trial the response rate was 23%. An average of 1.5 courses and a median of 5 weeks were necessary to achieve a response. The median duration of CR patients was 21 weeks and for PR patients it was 5 weeks. Response rates were 24% for Regimen A, 0 for Regimen B, and 1 of 8 for Regimen C. The CR rate for
AML
and AMML was 13%. Two of eight AMoL patients achieved a CR. Only 2 of 23 ALL patients responded, one of whom achieved a CR. Toxicity included moderate to severe
nausea and vomiting
, diarrhea, stomatitis, skin rash, and prolonged myelosuppression. 5-azacytidine has significant activity in the acute nonlymphoblastic leukemias.

Neocarzinostatin (NCZ), an acidic polypeptide antibiotic, was given to 47 patients with cancer and leukemia, and tolerance to two schedules, a single dose given as a 2 hour infusion and a continuous infusion over 5 days was investigated. Immediate reactions, including fever, chills, rigor, hypertension and mental confusion, were dose-limiting for the 2 hour infusion schedule, occurring at 3000 U/m2 and higher. Continuous administration for 5 days eliminated the immediate reactions and then hematological toxicity--often prolonged leukopenia and thrombocytopenia--became dose-limiting. Other toxicities of NCZ at both dose schedules included anemia, fever and chills, anorexia,
nausea and vomiting
, hepatic dysfunction, azotemia, hypophosphatemia, aminoaciduria, stomatitis, phlebitis and/or cellulitis at the venous infusion site and pruritus. Patients with solid tumors who had received little or no prior chemotherapy and had good bone marrow reserve tolerated up to 6000 U/m2/24 hours X 5 days. One patient with previously treated
acute myelocytic leukemia
was induced into a good partial remission lasting 10 weeks.

The compound 4'-(9-acridinylamino)methanesulfon-m-anisidide is a new derivative that was evaluated in a Phase 1 clinical trial. The schedule of drug administration consisted of daily i.v. injection for 3 consecutive days, repeated at 3-week intervals. Twenty-six patients received a total of 63 courses of 4'-(9-acridinylamino)methanesulfon-m-anisidide in a dose range from 4 to 50 mg/sq m/day. Hematopoietic toxicity was dose limiting, but it was of short duration and rapidly reversible. Mild
nausea and vomiting
were observed in 16% of the courses, and a mild degree of phlebitis was observed in 10% of the courses. Responses were observed in two patients with adenocarcinoma of the lung and one each of melanoma and
acute myeloblastic leukemia
. Phase 2 studies of 4'-(9-acridinylamino)methanesulfon-m-anisidide are planned at a starting dose of 40 mg/sq m/day for 3 days in good-risk patients and at 25 to 30 mg/sq m/day for 3 days in poor-risk patients. Course of treatment would be repeated at 21-day intervals.

Thirteen leukemic patients with disease refractory to conventional chemotherapy were treated with 1.0 to 7.5 g/m2 of Cytosine Arabinoside (Ara-C) over 29 drug cycles. Drug infusions were spaced at 12-hour intervals; a maximum of four doses was administered over 36 hours. After single dose tolerance had been established, three or four dose cycles were given at 2- to 30-day intervals. There were three partial remissions (PR) and one complete remission (CR) in a treatment group of four patients with
AML
, five with ALL, two with lymphoma converted to leukemic phase, one CML in blast crisis, and one promyelocytic leukemia. Five of the patients were septic and considered terminally ill at the time of treatment. All other patients had evidence of drug responsiveness. The nadir of the white count occurred from 3 to 12 days after treatment, with subsequent recovery of the peripheral granulocyte count between days 12 and 28. Toxicity included
nausea and vomiting
(GI symptoms) in twelve patients, central nervous system (CNS) disturbances in eight patients, one episode of inappropriate antidiuretic hormone syndromes (SIADH), one of hyperuricemia, and fever in eleven patients. There was no evidence of hepatic or renal dysfunction. These high doses of Ara-C appear useful for treatment of patients with refractory leukemia. Hospitalization is brief and toxicity acceptable.

Sixty-six children with acute leukemia, in advanced stages of their disease and resistant to conventional chemotherapy, received adriamycin for remssion induction. Seventeen of 46 (37%) evaluable children with acute lymphocytic leukemia achieved a complete remission, and 5 (11%) achieved a partial remission. Two of 12 evaluable children with
acute myelogenous leukemia
achieved a complete remission, while an additional 3 achieved a partial remission. Two children with erythroleukemia also achieved a complete remission. Previous therapy with daunorubicin did not affect the response rate. The main toxicities observed with adriamycin were myelosuppression, fever,
nausea and vomiting
, stomatitis, alopecia, and cardiac toxicity (ST segment changes and arrhythmias).

Forty-eight patients with
acute myelogenous leukemia
(
AML
) not eligible for anthracycline or mitoxantrone treatment, mostly due to cardiac contraindications, were given aggressive therapy using m-amsacrine (AMSA) in combination with conventional or high-dose cytarabine for remission induction. Twenty-nine patients (60.4%) responded to treatment, and complete remission was attained in 19 (39.6%), partial remission in 4 (8.3%) and death in bone marrow aplasia without detectable blasts in 6 patients (12.5%). Median time to granulocyte recovery was 32 days, median duration of relapse-free survival 199 days. One patient experienced a serious cardiac adverse event;
nausea and vomiting
were observed in 73%, diarrhea in 44%, and hepatoxicity in 29% of patients. All potentially AMSA-related side effects were fully reversible, and a lethal complication did not occur. It is concluded that combination chemotherapy with AMSA and Ara-C is also effective and tolerable in leukemic patients in whom cardiotoxic drugs are contraindicated.

Homoharringtonine (HHT) is a cephalotaxine alkaloid with reported efficacy in
acute myelogenous leukemia
(
AML
). In a phase II trial, we evaluated HHT 5 mg/m2 by continuous infusion daily for 9 days in patients with relapsed or refractory acute leukemia and blastic phase of chronic myelogenous leukemia (BLCML). Sixty-six patients were entered. There were 40 males and 26 females with a median age of 41 years (range 15-81). Of 43 patients with relapsed
AML
, seven achieved a complete remission (16%, 95% confidence interval 5%-27%). Although 11 patients with
AML
primarily resistant to an anthracycline/cytarabine combination did not respond, two of three patients primarily resistant to low-dose cytarabine achieved complete remission. No patients with acute lymphoblastic leukemia, biphenotypic leukemia, or BLCML responded. Hypotension during the administration of HHT was the most difficult toxicity encountered, requiring multiple interruptions of therapy in several patients and the administration of intravenous saline. Fluid retention and weight gain occurred in 29% of patients. Transient asymptomatic hyperglycemia was observed in 63% of patients. Other toxicity was mild and included
nausea and vomiting
, diarrhea, mucositis, hepatic dysfunction, and cardiac arrhythmias. As expected, severe myelosuppression occurred in all patients. HHT is well tolerated, but with unique problems associated with administration. It has demonstrable efficacy in pre-treated patients with
AML
, but its role in the treatment of this disease remains to be defined.

Of 6,099 children treated for malignancy, 16 (ages 3.5 to 18 years) developed acute appendicitis between 1962 and 1989. Fourteen had leukemia (ALL 10,
AML
4). One each had rhabdomyosarcoma and Ewing's sarcoma. Active malignancy at diagnosis was noted in 10, 4 of whom had severe neutropenia (absolute neutrophil count less than 500/mm3). Of all the leukemics (2,794/6,099), abdominal pain during induction was a frequent complaint. The incidence of appendicitis, however, was low (0.5%). Nine of the 16 patients presented classically, facilitating prompt diagnosis and treatment. Six diagnoses were delayed. Three of these patients presented atypically with vague, nonlocalized pain, abdominal distention, lack of abdominal guarding, fever, dehydration, diarrhea, and unusual symptoms such as upper gastrointestinal bleeding. In each of these 6 patients the appendix was ruptured. Delays led to complications and deaths. Three patients required perioperative transfusions to treat excessive bleeding and two patients with ruptured appendicitis developed wound abscesses. Two patients died; in one, ruptured appendix was diagnosed only at autopsy. The other patient died of uncontrolled sepsis. Typhlitis occurring during induction chemotherapy may present similarly and is the main differential diagnosis. Typhlitis will usually improve with medical treatment alone.
Nausea and vomiting
(13/16), right lower quadrant pain (13/16), guarding (14/16), tachycardia (12/16), fever (10/16), and rebound tenderness (10/16) were the most frequent signs and symptoms of appendicitis. Persistent localized abdominal pain and guarding, lack of improvement with medical treatment, clinical deterioration, and the development of a mass were our indications for laparotomy. Despite major improvements in therapy, there is still a 37.5% error rate in our ability to accurately diagnose appendicitis in pediatric cancer patients.

Fourteen patients with relapsed or refractory acute leukemia received combination chemotherapy of mitoxantrone 6 mg/m2/day intravenously for three to six days and cytosine arabinoside 60 mg/m2/day intravenously over 24 hours continuously for five to ten days. Complete remission was attained in six patients (42.9%) and partial response in two patients (14.3%). Six patients (42.9%) had resistant disease, and four patients (28.6%) died during the myelosuppressive phase. Of the patients achieving complete remission, four relapsed and other two continued complete remission up to 27.3 months. Median remission duration was approximately 10.6 months. No significant difference was found with regard to the efficacy of our regimen between
AML
and ALL. Hematological toxicity was no more severe than the prior cumulative chemotherapy. Major non-hematologic side effects were
nausea and vomiting
(71.4%), stomatitis (64.3%) and liver dysfunction (57.1%), which were moderate and manageable, while no cardiotoxicity was observed in any patient. In conclusion, the combination chemotherapy of mitoxantrone and conventional dose cytosine arabinoside is an effective salvage therapy in relapsed or refractory acute leukemia, and our regimen has possible utility as first-line chemotherapy in de novo acute leukemia also.
