    Notes: Background:  Castleman's disease (CD) is a rare low-grade B-cell lymphoproliferative disorder that can be associated with a variety of antibody-mediated paraneoplastic syndromes. The disease is classified clinically by two forms and three histologic variants.Methods:  We describe the clinical and pathological features of a 44-year-old woman who presented with an autoimmune hemolytic anemia, thrombocytosis, polyclonal gammopathy, axillary lymphadenopathy, hepatosplenomegaly, and several erythematous and violaceous nodules and plaques without scaling involving the trunk and extremities.Results:  Histologic examination of the skin lesions revealed a deep dermal and subcutaneous nodular mononuclear infiltrate composed primarily of polyclonal plasmacytoid cells without atypia and an increased vascular proliferation. Additional studies including a bone marrow and lymph node biopsy, serum and urine protein electrophoresis, and computed tomography scans supported the diagnosis of multicentric plasma cell variant of CD with an associated autoimmune paraneoplastic hemolytic anemia.Conclusion:  Cutaneous involvement in CD is part of the multicentric nature and should be considered in the differential diagnosis of a polyclonal plasma cell-rich lymphoproliferative disorder associated with paraneoplastic autoimmune disease.

    Notes: Abstract Purpose: An all-oral regimen of etoposide and cyclophosphamide was developed for use in poor-prognosis extensive disease small-cell lung cancer. Limited pharmacokinetic sampling was used to derive a pharmacodynamic model predictive of myelosuppression early in the course of therapy. Patients and methods: Eligible patients were chemotherapy-naive and had extensive disease small-cell lung cancer with either SWOG performance status 2 or serum albumin 〈3.5 g/dl. The first cohort (n = 18) received etoposide orally at 50 mg daily and cyclophosphamide orally at 50 mg daily days 1–14 every 28 days. Due to good hematologic tolerance, the second cohort (n = 39) received both agents orally at 50 mg twice daily days 1–14 every 28 days. Plasma etoposide levels were determined in samples drawn at baseline, and at 1 h, 2 h, and 23.5 h (trough) after the first dose. Linear regression analysis was used to determine pharmacokinetic and demographic parameters predictive of myelosuppression. Results: A total of 173 treatment cycles were delivered. Patients on the daily regimen had a 22% response rate (complete and partial), a 22% unconfirmed response rate, and a 5-month median survival, while patients on the twice-daily regimen had a 28% response rate (complete and partial), a 13% unconfirmed response rate, and a 7-month median survival. Granulocytopenia and alopecia were the most common toxicities seen. Significant granulocytopenia could be predicted for the twice-daily regimen according to the formula ln(AGC nadir)=7.80 − 1.88(trough), with an increased incidence of granulocytopenia if the etoposide trough value was ≥1.49 μg/ml. Conclusion: Oral etoposide and oral cyclophosphamide given days 1–14 every 28 days is well tolerated and results in an acceptable response rate and median survival in poor-prognosis (poor performance status or low serum albumin) extensive disease small-cell lung cancer. A trough etoposide level obtained within 24 h of starting therapy can predict severe granulocytopenia.

    Phase II study of sulofenur (LY 186641) (1993)

    Notes: Summary Sulofenur is a member of a new class of antineoplastic agents with a novel chemical structure and unique pharmacological and biological properties. Preclinical studies have demonstrated a wide spectrum of antitumor activity against murine solid tumors and human tumor xenografts. In phase I trials, only mild toxicities were observed. Twenty-six patients (pts), two of whom were inevaluable, with advanced non small cell lung cancer without prior chemotherapy were entered on this phase II trial. Pts received 800 mg/m2 sulofenur po Monday–Friday × 21 days, q 28 days. Seventeen male and 9 female pts with median performance status 1 received a median of 2 courses. Twenty pts had stage IV disease and 19 pts had adenocarcinoma, 6 squamous cell and 1 undifferentiated carcinoma. The main toxicity was grade 1 to 3 anemia in 16 (62%) pts, with hemolysis noted in 9 pts. Although methemoglobinemia was observed in 19 pts, it was severe in only 3 pts. Transient elevation of alkaline phosphatase was seen in 11 pts and one pt had a minor abnormality in glucose metabolism. Other common chemotherapy related side effects such as granulocytopenia or alopecia were not encountered with this agent. Of 24 evaluable pts, two pts had stable disease or minor response and 22 pts had progressive disease. In conclusion although sulofenur had only minor side effects, in the dosage and schedule used, it did not produce any significant response in advanced non-small cell lung cancer.
