Of 6,099 children treated for malignancy, 16 (ages 3.5 to 18 years) developed acute appendicitis between 1962 and 1989. Fourteen had leukemia (ALL 10, AML 4). One each had rhabdomyosarcoma and Ewing's sarcoma. Active malignancy at diagnosis was noted in 10, 4 of whom had severe neutropenia (absolute neutrophil count less than 500/mm3). Of all the leukemics (2,794/6,099), abdominal pain during induction was a frequent complaint. The incidence of appendicitis, however, was low (0.5%). Nine of the 16 patients presented classically, facilitating prompt diagnosis and treatment. Six diagnoses were delayed. Three of these patients presented atypically with vague, nonlocalized pain, abdominal distention, lack of abdominal guarding, fever, dehydration, diarrhea, and unusual symptoms such as upper gastrointestinal bleeding. In each of these 6 patients the appendix was ruptured. Delays led to complications and deaths. Three patients required perioperative transfusions to treat excessive bleeding and two patients with ruptured appendicitis developed wound abscesses. Two patients died; in one, ruptured appendix was diagnosed only at autopsy. The other patient died of uncontrolled sepsis. Typhlitis occurring during induction chemotherapy may present similarly and is the main differential diagnosis. Typhlitis will usually improve with medical treatment alone. Nausea and vomiting (13/16), right lower quadrant pain (13/16), guarding (14/16), tachycardia (12/16), fever (10/16), and rebound tenderness (10/16) were the most frequent signs and symptoms of appendicitis. Persistent localized abdominal pain and guarding, lack of improvement with medical treatment, clinical deterioration, and the development of a mass were our indications for laparotomy. Despite major improvements in therapy, there is still a 37.5% error rate in our ability to accurately diagnose appendicitis in pediatric cancer patients.

Hepatosplenic candidiasis has increased in frequency among immunocompromised hosts. Risk factors include hematologic malignancy, intensive chemotherapy, prolonged neutropenia, and treatment with broad-spectrum antibiotics. Patients most commonly present with abdominal pain, persistent fevers despite antibiotic therapy, and an elevated alkaline phosphatase level that is out of proportion to other hepatic enzyme levels. Gastrointestinal mucosal damage secondary to intensive chemotherapy may allow colonization with Candida species and subsequent seeding of the portal vein. Treatment has consisted of prolonged courses of amphotericin B, with mortality rates approaching 50%. We report a case of hepatosplenic candidiasis in a patient with acute myelogenous leukemia who had clinical and radiographic improvement during fluconazole therapy. Fluconazole may be an efficacious and less toxic alternative to amphotericin B.

A 3-year-old boy was transferred to our hospital because of fever, abdominal pain and severe systemic bone pain on October 16, 1989. Hematological examination showed hemoglobin 8.7 g/dl, white blood cell count 5300/microliters with 9% neutrophils and platelet count 5.5 x 10(4)/microliters. Bone marrow aspiration and biopsy revealed markedly necrotic cells. Blood chemistry showed transient elevation of CRP, serum LDH, FDP, FDP-Ddimer and fibrinogen. Tc99m pyrophosphate bone scanning showed multiple uptake spots in various bone. Although the sign of fever, abdominal pain and bone pain disappeared spontaneously after three weeks, anemia persisted. About two months later from bone marrow necrosis, abnormal cells appeared in the bone marrow. A diagnosis of AML (M3) was made and a combination chemotherapy started. This case is remarkable for elevation of acute phase protein in association with bone marrow necrosis.

Granulocytic sarcoma is an extramedullary tumor consisting of immature cells of the granulocytic series known to occur in patients with myelodysplastic syndrome, chronic myelogenous leukemia, or acute myelogenous leukemia. This tumor may involve nodes, cervix, bone and periosteum, and infrequently the small intestine. Granulocytic sarcoma rarely occurs in the colon and has not been previously described endoscopically. We encountered a 73-year-old man with myelodysplastic syndrome who presented with fever, diarrhea, and abdominal pain. Colonoscopic evaluation (focal ulceration, friability, and nodularity) was compatible with Crohn's disease, although histology showed a dense myeloid cell infiltrate characteristic of granulocytic sarcoma. In patients with myelodysplastic syndrome or acute or chronic myelogenous leukemia presenting with diarrhea, abdominal pain, and/or fever, colonoscopy and biopsy are indicated to determine if the colon is affected by granulocytic sarcoma.

High doses of cytosine arabinoside (ara-C) were administered by continuous infusion to 24 patients with acute leukemia in relapse or blast phase of chronic myelogenous leukemia (CML). Ara-C was infused at a dose rate of 250 mg/M2/hr for 36 to 72 hr. The major toxicities were myelosuppression, diarrhea, and abdominal pain. Other toxicities included pulmonary edema, neurotoxicity, and liver function abnormalities. The gastrointestinal toxicity was dose-limiting and a phase II dose was established at 250 mg/M2/hr for 60-72 hr. Four patients treated with this dose schedule had objective responses. Two patients with CML in blast phase returned to chronic phase and have remained stable without maintenance therapy for 12 and 18 months. Two patients with acute myelogenous leukemia in relapse entered complete remissions which continued unmaintained for 4 and 6 months. Steady-state plasma ara-C levels ranged between 7 and 24 x 10(-6) M, while ara-U levels were as high as 4.5 x 10(-4) M. There was no detectable accumulation of ara-C or ara-U during the infusion period. These findings would suggest that the continuous infusion of high dose ara-C may be useful in the treatment of acute leukemia and CML in blast crisis.

The treatment of acute leukemia in childhood has been increasingly successful. Infectious complications are the major cause of morbidity and mortality among these patients receiving aggressive chemotherapy. In particular, neutropenic enterocolitis or typhlitis has had a reported mortality of 50% to 100%. The authors reviewed a series of 77 previously untreated patients with acute myelogenous leukemia begun on treatment from March 1976 to June 1984 to better define the characteristics of typhlitis and its optimum management. Twenty-five patients had episodes of typhlitis, characterized by fever, abdominal pain, and tenderness, occurring during periods of neutropenia. Ten of these patients had watery diarrhea as a major additional symptom, and nine patients had a significant episode of gastrointestinal bleeding. In seven instances, blood culture results were positive, all for intestinal flora. The episodes of typhlitis occurred most frequently during the induction therapy (19 patients). Five patients experienced typhlitis during maintenance therapy, and one patient had acute appendicitis. Two patients had typhlitis during their reinduction therapy, and of note, one had had abdominal symptoms during her initial induction. All patients were treated initially with broad-spectrum antibiotics and bowel rest. Four criteria have been used for surgical intervention: (1) persistent gastrointestinal bleeding after resolution of neutropenia and thrombocytopenia and correction of clotting abnormalities; (2) evidence of free intraperitoneal perforation; (3) clinical deterioration requiring support with vasopressors, or large volumes of fluid, suggesting uncontrolled sepsis; and (4) development of symptoms of an intra-abdominal process, in the absence of neutropenia, which would normally require surgery. Using these criteria, five patients required surgical intervention for typhlitis or its sequelae and one for acute appendicitis. There was one perioperative death resulting from miliary tuberculosis. Among the 21 patients managed medically, there was 1 death resulting from typhlitis in a patient in whom surgery was deferred because of her multiple failures to enter remission.

A 41-year-old patient with acute myeloid leukemia was transplanted from an HLA-identical but ABO-incompatible sibling. The post-transplant course was complicated by pure erythrocyte aplasia and mild chronic graft-versus-host disease. Eleven months after transplant while on steroid therapy she developed abdominal pain rapidly followed by fatal fulminant hepatic failure. Varicella zoster virus (VZV) was detected using the polymerase chain reaction from blood and liver obtained at necropsy even though no skin manifestations of VZV were present. This case confirms previous reports of visceral VZV infection in the absence of skin lesions thus emphasising the importance of suspecting the presence of VZV in this clinical setting and outlines the possible value of PCR in the rapid diagnosis of infection.

A 43 year old woman in remission from acute myeloid leukaemia developed abdominal pain, severe melaena, diarrhoea and gram-negative septicaemia whilst severely pancytopenic following consolidation chemotherapy. Subsequently, serial abdominal X-rays showed a progressive toxic megacolon. Conservative management was attempted but, because of radiological evidence of increasing colonic dilatation and incipient perforation, an emergency defunctioning colostomy was performed. The patient recovered and 2 months later the caecostomy was reversed and a right hemicolectomy performed. This first described case of toxic megacolon following leukaemia treatment is compared with three previously described cases following cytotoxic chemotherapy for other conditions.

We describe a case of a 38-year-old female who presented with diarrhoea and abdominal pain 27 days after a second 'top-up' allogeneic marrow infusion for acute myeloid leukaemia (AML) in first remission. A clinical diagnosis of gut graft-versus-host disease (GVHD) was made. Technetium (99mTc)-labelled white cell scanning and intestinal permeability studies using 51Cr-EDTA and 14C-mannitol were undertaken to confirm the diagnosis. The 99mTc white cell scan showed extensive uptake in the small bowel and the urinary excretion of 51Cr-EDTA was increased, the results being consistent with intestinal inflammation and gut GVHD. 99mTc white cell scanning and intestinal permeability studies may assist in the diagnosis of gut GVHD and in assessing its extent and response to treatment.

A nationwide multi-center cooperative phase II clinical study of irinotecan hydrochloride (CPT-11) was conducted to evaluate its efficacy in intractable malignant lymphoma and acute leukemia. In malignant lymphoma, one course of CPT-11 consisted of intravenous drip infusion at a dose of 40 mg/m2 once daily for 3 consecutive days, performed once a week. In acute leukemia, one course of CPT-11 consisted of intravenous drip infusion at a dose of 15 to 20 mg/m2 a day twice daily for 7 consecutive days (1 cycle), performed every 2 to 4 weeks. Among the 79 patients with malignant lymphoma and 50 patients with acute leukemia enrolled in the study, 66 and 41 patients, respectively, completed treatment. These patients had all undergone chemotherapy prior to treatment. Among the malignant lymphomas, the response rate in non-Hodgkin's lymphoma (NHL), including 9 CRs, was 42% (26/62, 95% CI: 30-54%); of these there was a response rate of 39% (5/13), including 1 CR, in adult T-cell leukemia (ATL) as well. In Hodgkin's disease (HD), on the other hand, there were no cases in which efficacy was demonstrated (0/4). The overall response rate in malignant lymphoma was 39% (26/66), and the response rate even among the recurrent intransigent cases was 42% (16/38). The 50% survival time (MST) in the 74 eligible cases of malignant lymphoma was 153 days. In acute leukemia, on the other hand, partial remission was observed in 2 of 17 cases (12%) of acute lymphocytic leukemia (ALL), but no cases of remission were observed in the 24 patients with acute myelogenous leukemia (AML). The overall remission rate in acute leukemia was 5% (2/41, 95% CI: 1-14%). The principal adverse effects were myelosuppression in malignant lymphoma and gastrointestinal symptoms, including diarrhea, nausea/vomiting, anorexia and abdominal pain, in both malignant lymphoma and acute leukemia, and there was little organ damage to the heart, liver or kidney. Myelosuppression and gastrointestinal adverse effects were severe in some of the patients, so caution is required. Based on the above findings, CPT-11 appears to be efficacious in the treatment of non-Hodgkin's lymphoma.
