A Phase I study was conducted of 5-fluorouracil administered i.p. in a 2-liter volume of 1.5% Inpersol. The drug was administered via Tenckhoff peritoneal dialysis catheters to ten patients with tumors confined to the i.p. space. Dialysis concentrations ranged from 5 micro M to mM. Complications of the dialysis procedure alone included mild abdominal discomfort and 2 cases of gram-negative bacterial peritonitis, both easily controlled with antibiotics. 5-Fluorouracil caused the same pattern of toxicity as when administered by other routes. There was no local or central nervous system toxicity. Dose-limiting toxicity included pancytopenia and mucositis at a dialysis concentration of 4.5 to 5 mM administered for eight consecutive 4-hr exchanges. There were two documented responses in eight evaluable patients. 5-Fluorouracil concentrations were measured by high-pressure liquid chromatography. Peritoneal fluid concentrations decline in a first-order fashion with a half-life of 1.6 hr. The mean permeability area product was 14 ml/min. A mean of 82% of drug was absorbed in 4 hr. Plasma levels rise over the first 30 to 45 min and decline in a nonlinear fashion. Plasma levels are substantially lower than are peritoneal fluid levels. Mean 4-hr peritoneal fluid concentration was 298 times the simultaneously measured plasma levels. Total body clearance ranged from 0.9 to 15 liters/min and declined with increasing dialysate concentration. We conclude the i.p. route is a relatively safe way to deliver high concentrations and large amounts of drug to the i.p. cavity with a significant pharmacological advantage over conventional routes of administration.

A 72-year-old woman was admitted with left cervical lymphadenopathy, high fever, pancytopenia and liver dysfunction. Bone marrow aspiration showed infiltration of large atypical lymphoid cells and hemophagocytic histiocytes, thus suggesting a diagnosis of lymphoma associated hemophagocytic syndrome (LAHS). An abdominal CT scan revealed multiple low-density areas in the liver, and the patient's liver function rapidly deteriorated. Histologically, the cervical biopsy showed lymphoma cell infiltration with prominent necrosis and karyorrhectic debris. The lymphoma cells expressed CD3+, CD4-, CD8+, CD20-, CD56+/-, TIA-1+, granzyme B+, and EBER was positive using in situ hybridization. DNA analysis of the TCR beta and gamma chain gene with the Southern blot showed rearranged bands. These findings were compatible with those of EB-virus associated peripheral T-cell lymphoma. After chemotherapy with the THP-COP regimen, the patient's liver dysfunction improved rapidly, but she died from bacterial peritonitis due to perforation of a recurrent duodenal ulcer. Post-mortem examination of the liver showed multiple irregular massive necroses of the hepatocytes, where no lymphoma cell infiltration was present. Hemophagocytic histiocytosis was remarkable in the bone marrow, spleen, lymph nodes, and liver. Marked elevation of serum levels of cytokines such as TNF-alpha or IFN-gamma suggests that these cytokines played an important role in the pathogenesis of the hepatic cell necrosis.
