Fine needle aspiration (FNA) was performed under ultrasound guidance on 17 abdominal masses in 16 pediatric patients at Baragwanath Hospital. The aspirated cellular material was assessed by conventional cytomorphology and by electron microscopy (EM). A diagnosis of malignancy was rendered for all 15 tumors that were adequately sampled (88.2%); the remaining 2 masses yielded insufficient material for either light microscopy or EM. Cytologic cell typing (including the use of EM) was successful in 12 of the 15 tumors (80%) as compared with the histologic diagnosis. EM was in agreement with the initial cytologic diagnosis in eight tumors, but corrected the initial impression in four tumors. The tumors with adequate aspirates included nine nephroblastomas and single examples of neuroblastoma, hepatoblastoma, non-Hodgkin's lymphoma, rhabdomyosarcoma, renal carcinoma and malignant rhabdoid tumor. The last three were not accurately typed by cytology plus EM. These preliminary results suggest that FNA cytology with adjunctive EM could become a useful technique in the preoperative assessment of pediatric abdominal tumors.

10 normals and 37 patients with Hodgkins' and non-Hodgkin's lymphoma were examined by MRT as part of a prospective study (lumbar spine, pelvis, proximal femora). In about half the patients the MR images showed diffuse or focal areas of reduced signal intensity in the bone marrow. The observation of reduced signal areas corresponded with the pathological findings from iliac crest biopsies. To improve diagnostic accuracy, the signal intensity from a chosen region of interest was related quantitatively to a standard level.

This study was undertaken to investigate the pharmacokinetics of etoposide for optimizing its oral dosage in elderly patients with non-Hodgkin's lymphoma (NHL) using the fraction of dose absorbed calculated from the data generated from first oral and intravenous doses in the same patient. Twenty-three NHL patients (ages 61-95 years) entered this study. Each received 50 mg/m2 of etoposide by 1-hour i.v. infusion, which was repeated every 24 hours for 5 days. The second cycle commenced on day 21, with etoposide being administered by mouth at a dose as close to 50 mg/m2 as possible. Serial blood samples were collected and analyzed for etoposide by HPLC. The fraction of dose absorbed (F) was calculated as F = (AUCor/AUCi.v.) (Di.v./Dor), and etoposide was then given orally for the following 20 days at a daily dose equivalent to Dor/F. After 1 week free of etoposide administration, a second cycle of oral etoposide at the adjusted dose was given for 21 days. The mean +/- SD values for t1/2 beta, tmax, Cmax, CLTor, and MRT observed following the first oral dose were 8.98 +/- 4.84 h, 1.39 +/- 0.96 h, 0.083 +/- 0.046 mg.L-1/mg.m-2, 1.89 +/- 1.2 L.h-1/m2, and 10.37 +/- 2.76 h, respectively, and those observed following the first intravenous dose were 8.05 +/- 5.11 h, 1.57 +/- 0.17 h, 0.142 +/- 0.043 mg.L-1/mg.m-2, 1.25 +/- 0.44 L.h-1/m2, and 7.69 +/- 1.53 h, respectively. The mean +/- SD of F was 0.80 +/- 0.34. The data obtained indicate that optimization of etoposide oral dosage using F yielded good clinical results while keeping the morbidity at a level that is similar to that of the i.v. administration.

The purging efficacy of positive selection of autologous CD34+ PBSC with a clinical scale method of magnetic-activated cell sorting system (CliniMACS) was investigated in 48 patients with non-Hodgkin's lymphoma (NHL). The median purity and recovery rate of the CD34+ cells post-selection were 93.3% (range 32.6-99.3) and 72.2% (range 20.5-309.8), respectively. The real-time PCR method to detect the patient-specific monoclonal immunoglobulin heavy chain gene rearrangement (minimal residual tumor; MRT) and CD19 and CD20 positivities were used for the detection of contaminating NHL cells before and after CD34+ selection. After selection, the median (range) depletion rate of MRT was 2.53 (1.52-4.78) log, and that of CD19+ cell and CD20+ cell was 2.46 (0.74-3.64) log and 2.32 (0.40-4.01) log, respectively. In 41 patients, high-dose chemotherapy was performed, followed by the transplantation of the isolated CD34+ cells. Rapid neutrophil recovery as well as platelet recovery was seen with a median time to reach 0.5 x 10(9)/l neutrophils of 10 days (range 8-13) and 20 x 10(9)/l platelets of 14 days (range 10-34), respectively. The present study demonstrated that CliniMACS is a highly effective positive selection method and a high purging efficacy could be obtained without compromising the hematopoietic reconstitution capacity of the graft in NHL patients undergoing high-dose chemotherapy.

Primary diseases of the spleen are relatively rare. More frequently, the spleen is involved secondarily in hematological, oncological, infectious, immunological, vascular, and other systemic diseases. The spleen is the most commonly injured organ in blunt abdominal trauma. Anatomical and physiological basics are explained, in addition to embryological facts with resulting abnormalities, such as accessory and "wandering" spleen, and polysplenia. The most frequent primary and secondary diseases of the spleen, including rare diagnoses, are presented and illustrated. Hemangioma represents the most common primary benign tumor, and lymphoma the most common primary malignant tumor of the spleen. Diagnostic imaging does not a allow safe differentiation between Hodgkin's and non-Hodgkin's lymphoma. One section deals with the clinical value and diagnostic workup of incidentally detected lesions. Simple cysts and calcifications need neither clarification nor a follow-up examination. Atypical cysts should be controlled within 3-6 months. Additional clarification using CT or MRT should be reserved for cases with a strong suspicion of clinically relevant primary or secondary splenic disease.
