Aleukemic leukemia cutis preceding acute monocytic leukemia: a case report.

Aleukemic leukemia cutis is an extremely rare clinical presentation in patients who eventually develop acute leukemia, usually of monocytic lineage. This condition is associated with a very poor prognosis and is often difficult to diagnose. We report a case of a 33 years old female with leukemia cutis preceding the onset of acute monocytic leukemia by four months.

Dose escalation studies of cytarabine, daunorubicin, and etoposide with and without multidrug resistance modulation with PSC-833 in untreated adults with acute myeloid leukemia younger than 60 years: final induction results of Cancer and Leukemia Group B Study 9621.

Purpose: P-glycoprotein (Pgp) is strongly inhibited by PSC-833. A chemotherapy dose-escalation study was performed with PSC-833 in patients younger than 60 years with untreated acute myeloid leukemia. Clinical rather than pharmacokinetic end points were used to develop two induction therapies containing drugs susceptible to Pgp-mediated efflux and associated with comparable toxicities at the maximum-tolerated doses.

Lineage specific treatment of adult patients with acute lymphoblastic leukemia in first remission with anti-B4-blocked ricin or high-dose cytarabine: Cancer and Leukemia Group B Study 9311.

Background: Anti-B4-blocked ricin is an immunotoxin comprised of an anti-CD19 murine monoclonal antibody (B4) conjugated to blocked ricin, which has cytotoxic activity in patients with lymphoid malignancies.

Methods: Adults with untreated acute lymphoblastic leukemia (ALL) were treated with a previously developed and tested chemotherapeutic regimen. Patients with CD19 positive ALL were given anti-B4-blocked ricin as 2 7-day continuous infusions 1 week apart.

Treatment of relapsed or refractory acute myeloid leukemia with humanized anti-CD33 monoclonal antibody HuM195.

HuM195 is a humanized, unconjugated, anti-CD33 monoclonal antibody. Fifty adult patients with relapsed or refractory AML were randomized to receive HuM195 at a dose of 12 or 36 mg/m(2) by intravenous infusion over 4 h on days 1-4 and 15-18. Patients with stable or responding disease received two additional cycles on days 29-32 and 43-46.

Excellent response to interferon therapy in a patient with hypereosinophilic syndrome and elevated serum immunoglobulin E levels.

The hypereosinophilic syndrome (HES) is a heterogeneous disease characterized by sustained eosinophilia for a period of at least six months with evidence of organ involvement. Its manifestations range from a benign disorder not requiring any therapy to an aggressive, malignant variety refractory to common treatments. Diverse therapies have been used, including steroids, hydroxyurea, and chemotherapy, with variable responses.

Simultaneous occurrence of Hodgkin's disease and chronic lymphocyte leukemia: a unique presentation.

Chronic lymphocytic leukemia (CLL) is a chronic, low-grade hematologic malignancy that can transform to a large cell non-Hodgkin's lymphoma (Richter's syndrome), which is associated with an unfavorable prognosis. A distinct Hodgkin's disease subgroup of lymphomatous CLL transformation has been well characterized. We describe a patient presenting with simultaneous manifestations of CLL and Hodgkin's disease.

Long-term follow-up of three randomized trials comparing idarubicin and daunorubicin as induction therapies for patients with untreated acute myeloid leukemia.

Background: Most clinical trials for acute leukemia have reported results after 2-3 years of follow-up. Comparisons between the original data and longer-term follow-up data may be of interest, particularly with regard to promising new therapies.

Methods: In 1996, survival data were updated from three prospective, randomized comparisons of idarubicin and daunorubicin that began in 1984 and 1985.

Cardioprotection with dexrazoxane for doxorubicin-containing therapy in advanced breast cancer.

Purpose: To determine the cardioprotective effect of dexrazoxane (DZR) used in a doxorubicin-based combination therapy in advanced breast cancer.

Patients And Methods: Between November 1988 and January 1991, 534 patients with advanced breast cancer were randomized to two multicenter, double-blind studies (088001 and 088006). Patients received fluorouracil, doxorubicin, and cyclophosphamide (FAC) with either DZR (DZR-to-doxorubicin ratio, 10:1) or placebo (PLA) every 3 weeks and were monitored with serial multiplegated acquisition (MUGA) scans.

T-cell rich B-cell lymphoma masquerading as Hodgkin disease: excellent outcome to inadequate therapy.

T-cell rich B-cell lymphomas (TCRBCL) are characterized as non-Hodgkin lymphomas with a minor population of malignant B-cells scattered among predominant, reactive T-lymphocytes. This entity can easily be confused with lymphocyte-predominant Hodgkin disease (HD-LP), resulting in inappropriate therapy and a poor outcome. Because of their similarity, the pathology of patients treated for HD-LP with an inadequate or short-lived response to therapy should always be reviewed by an expert hematopathologist.

A phase III trial comparing idarubicin and daunorubicin in combination with cytarabine in acute myelogenous leukemia: a Southeastern Cancer Study Group Study.

Purpose: A randomized clinical trial was undertaken to compare the therapeutic effectiveness of idarubicin (IDR) to daunorubicin (DNR), and both were given in combination with cytarabine (CA) in acute myelogenous leukemic (AML) patients.

Patients And Methods: Newly diagnosed patients were given a daily infusion of CA (100 mg/m2) for 7 days and were assigned randomly to receive DNR (45 mg/m2) or IDR (12 mg/m2) daily for the first 3 days. Those patients who achieved a complete remission (CR) were given three consolidation courses that consisted of CA (100 mg/m2 intravenously [IV]) and thioguanine (TG; 100 mg/m2 orally) every 12 hours for 5 days and either DNR (50 mg/m2) or IDR (15 mg/m2) on the first day of each cycle.

A phase III randomized study comparing cisplatin and fluorouracil as single agents and in combination for advanced squamous cell carcinoma of the head and neck.

Purpose: To determine whether combination chemotherapy is superior to single agents for recurrent/metastatic head and neck cancer, we compared the efficacy and toxicity of cisplatin (CP) and fluorouracil (5-FU), alone and in combination in a phase III trial.

Patients And Methods: Two hundred forty-nine patients with recurrent head and neck cancer were randomized to one of three treatments: CP (100 mg/m2) and 5-FU (1 g/m2 x 4), CP, or 5-FU every 3 weeks.

Results: The overall response rate to the combination (32%) was superior to that of CP (17%) or 5-FU (13%) (P = .

Postsurgical adjuvant chemotherapy with or without radiotherapy in women with breast cancer and positive axillary nodes: a South-Eastern Cancer Study Group (SEG) Trial.

In a prospective study of 622 women with breast cancer, those with one to three histologically positive axillary lymph nodes were randomised after mastectomy to receive cyclophosphamide 100 mg/m2 orally on days 1-14, methotrexate 40 mg/m2 intravenously on days 1 and 8, and fluorouracil 600 mg/m2 intravenously on days 1 and 8 every 28 days for six cycles (CMF x six), or for twelve cycles of the same chemotherapy (CMF x 12). Those with > or = four positive nodes were randomised to one of these two groups or to 5000 cGy of postmastectomy regional radiotherapy (RT) followed by six cycles of the same chemotherapy (RT + CMF x six). With about 10 years median follow-up, there was no significant difference in survival or disease-free survival among the three groups.

Multicenter phase II trial of brequinar sodium in patients with advanced squamous-cell carcinoma of the head and neck.

A total of 19 patients with advanced squamous-cell carcinoma of the head and neck who had not previously been exposed to chemotherapy were treated with brequinar sodium as first-line chemotherapy. Brequinar was given intravenously at a median weekly dose of 1,200 mg/m2. The toxicity was moderate, with 7 patients (37%) experiencing grade 3 or 4 toxicity.

Carcinocythemia in a patient with rhabdomyosarcoma.

Solid tumor cells are rarely seen in peripheral blood smears. When this occurs the term carcinocythemia is used. This report describes an 18-year-old female who presented with a painless lump in the labia majora associated with pancytopenia.

Concomitant cisplatin chemotherapy and radiotherapy in advanced mucosal squamous cell carcinoma of the head and neck. Long-term results of the Radiation Therapy Oncology Group study 81-17.

One hundred twenty-four eligible patients with advanced mucosal squamous cell carcinoma of the head and neck were entered into a pilot study of concomitant cisplatin (100 mg/m2 given every 3 weeks for three doses) and standard irradiation. The initial complete response (CR) was 71% with an additional two cases salvaged by surgery for an overall 73% CR. When no keratin was identified in the histologic specimen (41 patients) the CR was 90%.

Severe hemolysis and red cell fragmentation caused by the combination of a spectrin mutation with a thrombotic microangiopathy.

Two patients are described who presented with severe hemolysis and erythrocyte fragmentation. One patient had renal allograft rejection and disseminated intravascular coagulation, and the other had thrombotic thrombocytopenia purpura. The severity of hemolysis and the red cell abnormalities were considerably more profound than usually seen in patients with thrombotic microangiopathies.

Concurrent radiotherapy and chemotherapy with cisplatin in inoperable squamous cell carcinoma of the head and neck. An RTOG Study.

In patients who have locally advanced and inoperable head and neck cancer, the achievement of initial local control (complete response) of the disease with initial definitive treatment with radiotherapy (RT) with or without chemotherapy, is an important prognostic factor for overall survival. Cisplatin 100 mg/M2-intravenously (IV) with hydration and mannitol diuresis was given every 3 weeks for three doses concurrently with definitive radiotherapy (followed by salvage surgery [if possible] for persistent disease) was activated by the Radiation Therapy Oncology Group (RTOG) in 1981. One hundred thirty-four patients were initially registered and 124 were eligible and analyzed for this report.

A phase II trial of diaziquone in patients with head and neck cancer.

Diaziquone (AZQ) is a lipophilic alkylating agent which crosses the blood-brain barrier and has marked antitumor activity in a broad spectrum of murine tumor systems. Myelosuppression has been the dose-limiting toxicity in phase I trials. In this study 36 patients with head and neck cancer received diaziquone.

Alternating sequential combination chemotherapy in the management of advanced Hodgkin's disease. A Southeastern Cancer Study Group trial.

The Southeastern Cancer Study Group has explored the use of alternating sequential combination chemotherapy in advanced Hodgkin's disease. Two hundred twelve evaluable patients were randomly assigned to treatment with the six-drug combination, BCNU, cyclophosphamide, vinblastine, procarbazine, prednisone, and bleomycin (BCVPP-Bleo) or with the same drugs alternating in monthly cycles with doxorubicin, dacarbazine, and bleomycin. Both regimens produced complete response rates of approximately 73%.

Acute lymphoblastic leukemia with unusual cytoplasmic granulation: a morphologic, cytochemical, and ultrastructural study.

The classification of the acute leukemias depends mainly on the morphologic and cytochemical evaluation of the blast forms. One of the main accepted morphologic criteria in the differentiation between acute lymphoblastic leukemia (ALL) and acute myeloblastic leukemia (AML) is the absence of granules in the blast cells of ALL. We evaluated a patient with ALL in whom granules were present in the cytoplasm of 35% of the blast cells, as seen in AML.
