Based on in vitro evidence of time-dependent synergistic kill of HL-60 leukemia cells exposed to
Ara-C
and mitoxantrone, 44 patients with relapsed or refractory AML and 3 with blastic CML were treated with a timed sequence of both drugs. There were 25 females and 22 males, with a median age of 53 (range 21-75). Of 31 patients with relapsed AML, 24 had one prior remission, 6 had two and 1 had three. Of these, 15 had failed a second reinduction attempt. Thirteen patients were primarily refractory to induction with
Ara-C
plus daunorubicin. Each dose of
Ara-C
, 500 mg/m2, was followed after 6 hr by mitoxantrone, 5 mg/m2, and the sequence was repeated four to six times (44-68 hr) in different cohorts of patients. All but two patients (one with blastic CML and one in relapse and refractory) are evaluable for response and toxicity. Of 16 patients in relapse without prior reinduction 7 achieved CR and 3 PR (62% response rate); there were 3 CR in the 14 patients who were in relapse and refractory (21% response rate) and 4 CR and 1 PR (35% response rate) in the 14 patients with primary anthracycline resistance. Five of seven patients previously exposed to mitoxantrone achieved CR. Response lasted from 2 to 42 months, with two patients alive and in continuing remission at 34 and 42 months. Average marrow recovery was seen after 25 days and time to remission was 30 days. Six patients died in induction (four from
sepsis
and two from the tumor lysis syndrome) and 21 had progressive disease. Chemotherapy was well tolerated with minor nausea and vomiting in 13 patients, moderate in 20, and severe in 2. Most patients did not have evidence of drug-induced mucositis: it was minor in 9 and moderate in 2. Renal dysfunction was attributable to the use of nephrotoxic antibiotics. Hepatic dysfunction was reversible and was minor in 10 patients, moderate in 13, and severe in 3. Sequential, timed administration of intermediate-dose
Ara-C
and mitoxantrone is an active and well-tolerated antileukemic regimen.

Based on the demonstration of in vitro and in vivo synergy between cytosine arabinoside (
Ara-C
) and cis-diamminedichloroplatinum (CDDP), we designed a Phase II trial of
Ara-C
plus CDDP for patients with advanced squamous cancers of the head and neck and esophagus. Sixteen patients were treated on a unique schedule of continuous-infusion
Ara-C
, 30 mg/m2/day over 72 h, plus CDDP, 30 mg/m2/day at hours 12, 36, and 60 of the
Ara-C
infusion. The objective response rate was 38% (95% confidence limits 14-62%), with two patients achieving complete clinical and radiographic response (9 and 27+ months duration) and four partial responses (median duration 4 months, range 1-7 months). There was no CDDP-related nephro- or neurotoxicities, but a flu-like syndrome of anorexia and asthenia was common. Myelosuppression was the dose-limiting toxicity, necessitating
Ara-C
dose adjustments in 11 cycles of therapy and leading to fatal
sepsis
in one patient. We conclude that the activity of this combination, though comparable to that of other CDDP-containing regimens, offers no significant therapeutic advantage, and given the excessive hematologic toxicity, should not be investigated further.

As increasing numbers of children and adults with leukemia have become long-term survivors, the impact of an existing pregnancy on leukemia treatment, as well as the significance of prior leukemia therapy on future pregnancies, have become sources of concern. The information presently available, derived from small, retrospective series or case reports, indicates that leukemia may develop throughout pregnancy, that a leukemia woman who is pregnant need not undergo an abortion if she does not desire, and that standard antileukemic chemotherapy can be administered safely during the second and third trimesters. The antifolates (eg, methotrexate), being particularly teratogenic, should be avoided during the first trimester.
Cytarabine
and anthracycline treatment, the fundamental components of management for patients with AML, has not been associated with birth defects. The risk for placental injury,
sepsis
, and spontaneous abortion or premature birth is undoubtedly increased in women who experience the periodic episodes of myelosuppression that accompany leukemia treatment. Once remission has been achieved, decisions regarding adjustments of the intensity of therapy must be made with each individual patient; such dose alterations may diminish the mother's potential for long-term leukemia control, while possibly securing the viability of the fetus. Similarly, issues such as elective delivery prior to term and vaginal delivery v caesarean section should be resolved on a patient-by-patient basis. The offspring of leukemic mothers appear to mature normally.

Based on remarkable activity in refractory lymphomas, a combination of etoposide, cisplatin (both administered by 4-day continuous infusions), cytarabine (
Ara-C
), and dexamethasone (EDAP) was evaluated in 20 patients with advanced myeloma refractory to standard melphalan and prednisone (MP) and/or vincristine, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and dexamethasone (VAD) and even to high doses of melphalan (HDM) (seven patients). Forty percent of patients responded regardless of previously recognized risk factors (eg, duration of drug resistance, tumor mass, and serum lactic dehydrogenase [LDH] level). While the median survival was only 4.5 months, patients with good performance (Zubrod less than 2) and low or intermediate tumor stage survived more than 14 months compared with only 2 months for the remaining group. EDAP could be readily administered in the outpatient clinic, but neutropenic fever prompted hospital admission in 80% of patients, half of whom developed penumonia and
sepsis
, a fatal outcome in four patients. Severe myelosuppression was of short duration, so that subsequent cycles could be administered every 3 to 4 weeks. No serious extramedullary toxicity, including renal toxicity, was encountered. Marrow toxicity and hence infectious complications may be reduced by elimination of
Ara-C
without compromising treatment efficacy. We conclude that the lack of cross-resistance with VAD and even HDM makes EDAP or a similar combination an attractive regiment to be formally explored in an alternating sequence with VAD in high-risk myeloma.

Thirty-five patients with acute myelogenous leukemia were treated with aclacinomycin A (60 mg/m2/day for 5 days) and VP-16-213 (100 mg/m2/day for 5 days). All were previously treated and had relapsed or were refractory to primary treatment. Most patients (28) had received prior DAT (daunorubicin, cytosine arabinoside, and 6-thioguanine) induction therapy followed by one or more courses of high-dose cytosine arabinoside (HD-Ara C) as consolidation therapy or as treatment for relapse. One patient was in her fourth relapse, one had relapsed acute megakaryoblastic leukemia (following remission with DAT and HD-
Ara-C
), one had a treatment-induced leukemia, and four patients were treated for primary treatment failures following two induction courses with DAT or a similar regimen. Fourteen patients had infections at start of therapy. Ten patients died within 14 days of treatment, all from
sepsis
or bleeding, before their marrow could be evaluated for leukemic response. Fourteen patients (40%) responded; 12 (34%) entered complete remission and two (6%) a partial remission (PR). Two of the four patients who were treated for primary treatment failures went into CR. The median CR duration was 99 days (range 30 to 455 days). Side effects from this treatment were similar to the conventional DAT regimen, although the gastrointestinal toxicity and mucositis appeared to be more severe. In addition, two of the patients had severe but reversible ventricular arrhythmias. The overall response (40%) and CR rate (34%) in this group of previously treated AML patients is encouraging, and further studies are needed to evaluate these preliminary findings.

Neutrophilic eccrine hidradenitis (NEH) is a recently described neutrophilic dermatosis associated with acute myelogenous leukemia (AML) and chemotherapy. This disorder is a distinct clinicopathologic entity separate from leukemid reactions and other neutrophilic dermatoses. We describe two cases in which plaques or nodules developed in the second week after initiation of induction chemotherapy for AML. The lesions regressed in 1 week and recurred in one case when induction chemotherapy was given a second time. Histologically, the findings were similar in each case. Neutrophils palisaded about and infiltrated the eccrine coil in which necrosis of secretory epithelium was present. Focal mucinous degeneration of the eccrine adipose tissue cuff was the only other significant alteration. No vasculitis was observed. Cultures and histologic preparations for pathogenic organisms were negative.
Cytarabine
was the chemotherapeutic agent used in all three cases. NEH most likely represents either an unusual response caused by cytarabine or a manifestation of AML. Recognition of NEH is important in order to exclude other neutrophilic dermatoses associated with AML, such as
sepsis
and leukemia cutis, which may appear clinically similar.

We report three cases of fulminant
sepsis
due to viridans streptococci in leukemic children treated with high-dose cytosine arabinoside (
Ara-C
). The major predisposing factors to this occurrence are the presence of oropharingeal mucositis, which is the entry of streptococci into the bloodstream, and the use of antibiotic prophylactic regimens against gram-negative bacteria. In order to avoid fatal events during viridans streptococci
sepsis
, specific measures such as penicillin prophylaxis or early antibiotic treatment are needed. We suggest that the prompt empiric use of a glycopeptide antibiotic in addition to the conventional association of a beta-lactam plus an aminoglycoside may significantly decrease the mortality rate due to fulminant streptococci
sepsis
while the patient is severely neutropenic. In this regard, our current policy considers the addition of an anti-gram-positive antibiotic to the first-choice fever treatment in neutropenic patients who have received high-dose
Ara-C
.

A 75-year-old female was admitted to our hospital because of fever and hypotension. The peripheral blood showed 400 leukocytes/microliters with 13,000/microliters platelets. Bone marrow puncture revealed that NCC stood at 14,000 with 50.0% blasts. The surface characters of the blasts were CD13+, CD33+, and HLA-DR+, and blood culture tests were positive. Coagulation tests revealed DIC. Based on the foregoing results, hypoplastic leukemia was diagnosed accompanied by
sepsis
and DIC, and was placed on the concomitant administration of a combination of low dose
Ara-C
and M-CSF. After 14 days of
Ara-C
administration and 26 days of M-CSF, her clinical symptoms improved, with the peripheral blood showing a WBC of 2,800/microliters and platelet count of 111,000/microliters. The percentage of myeloblasts decreased to 7.0%. After the administration of
Ara-C
was suspended for 2 weeks, another course of low dose
Ara-C
plus M-CSF administration was carried out and the patient achieved full remission. M-CSF stimulates not only the production of monocytes but increases the number of neutrophils and platelets through monocytes. It is also expected that tumoricidal activity may be realized by the activation of monocytes. In this patients, the concomitant administration of M-CSF and low dose
Ara-C
was remarkably effective in treating hypoplastic leukemia with severe complication. This result suggests that M-CSF will be useful for the treatment of leukemia.

Gram-negative
sepsis
/septic shock in the newborn continues to be a major medical problem, causing high mortality. Hyperglycemia followed by hypoglycemia is a common symptom in endotoxic shock. However, the mechanism of newborn glucoregulatory response to endotoxin has not been well understood. Paradoxically, monocyte-phagocytes can contribute to shock by overwhelming secretion of cytokines and also host defense by detoxifying endotoxin. Since monocyte-phagocyte function is immature in the newborn, this study was performed to evaluate Kupffer cell's role in liver glycogenolysis during endotoxic shock. Endotoxin (LPS) induced hyperglycemia in 10-day-old rats, and increased net glucose output in the isolated perfused liver. 1)
Cytarabine
decreased Kupffer cell function (decreased hepatic colloid carbon uptake) and blunted LPS-increased liver net glucose output in the
Cytarabine
+ LPS-treated group (104 +/- 4 vs. 146 +/- 3 micrograms/min/g wet liver in the LPS-treated group: P < .001). 2) Indomethacin (IND) suppressed LPS-induced liver net glucose output in the LPS + IND-treated group (133 +/- 5 vs. 146 +/- 3 micrograms/min/g wet liver, P < .05). Thus, prostaglandins were suggested to contribute to glycogenolysis in the 10-day-old rat liver. 3) Phorbol 12-myristate 13-acetate (PMA) increased liver net glucose output (166 +/- 4 micrograms/min/g wet liver), and H-7, a protein kinase C inhibitor, blunted PMA-induced liver glucose output (140 +/- 2 micrograms/min/g wet liver, P < .05). H-7 enhanced LPS-induced liver net glucose output (196 +/- 9 micrograms/min/g wet liver, P < .01). Therefore, protein kinase C may not be the dominant cell signaling system for LPS stimulation in suckling rat Kupffer cells.

From July 1987 to July 1991, 12 children underwent AMBT following high-dose cytarabine (HD
Ara-C
) plus 14.4 Gy hyperfractionated total body irradiation (hyfr-TBI) for early isolated extramedullary relapse of ALL, while in first BM remission. No patient received intrathecal prophylaxis following AMBT. One patient died on day +5 due to
sepsis
and three patients, two of them transplanted in second and third CNS relapse, respectively, died from BM relapse occurring 1.5, 4 and 5 months after AMBT. Eight of the 12 survive disease-free with a median follow-up of 24 months (range 14-62 months). The toxicity of HD
Ara-C
plus hyfr-TBI was acceptable and well controlled with supportive therapy. These results suggest that ABMT following HD
Ara-C
plus hyfr-TBI may eradicate leukemia from extramedullary sites of ALL relapse.
