Two cases of hepatosplenic candidiasis (HSC) are reported occurring after protracted episodes of
neutropenia
, induced by chemotherapy for acute leukemia in one case and drug hypersensitivity in the other. The disease presented with persistent or recurrent fever after correction of the
neutropenia
and with splenomegaly. The alkaline phosphatases were elevated. The diagnosis was strongly suggested by abdominal ultrasonography, CT scan and
MRI
, which showed multiple hepatosplenic defects. It was confirmed by serologic tests for candidiasis, the presence, in 1 case, of circulating candida antigens, and the rapid response to amphotericin B. The diagnosis of HSC should be considered in patients with persistent fever after an episode of
neutropenia
. Ideally, histologic confirmation is desirable, but this is often obtainable only by open liver biopsy, an aggressive procedure in such patients. Failing this, our 2 cases stress the diagnostic value of noninvasive imaging techniques, serological testing (in particular the discovery of circulating candida antigens) and the response to amphotericin B.

Several clinical trials have demonstrated that cisplatin-based chemotherapy for primary intracranial germ-cell tumors is effective as a neoadjuvant chemotherapy. In this report, we describe a 6-year-old boy, Down syndrome and Hirschsprung's disease with intracranial pure yolk sac tumor treated by combined chemotherapy with cisplatin, vinblastine, bleomycin and cyclophosphamide (modified VAB-6 regimen). He had been admitted to our hospital because of intractable vomiting, and left facial nerve palsy since 1 month before. An
MRI
revealed an enlarged mass, 4cm in diameter, in the left cerebello-pontine angle with uniformal enhancement by Gd-DTPA, and bilateral ventricular dilatation. He was found to have increased serum alpha-fetoprotein level (AFP 11, 786ng/ml), but not human chorionic gonadotropin beta-subunit. After a partial resection of the tumor, diagnosed as pure yolk sac tumor, and ventriculo-peritoneal shunt, three courses of combined chemotherapy with cisplatin, bleomycin, vinblastine and cyclophosphamide (modified VAB-6 therapy) were carried out. The serum AFP level returned to normal, and the tumor mass entirely disappeared (a complete response) on
MRI
after the second course of chemotherapy. However, cisplatin-induced vomiting and mild
neutropenia
and renal tubular injury developed after the third course of chemotherapy. Irrespective of administration of recombinant human G-CSF and broad spectrum antibiotics, he suffered from pneumonia and died of septic shock and multiple organ failure. Autopsy showed microscopic residual tumors. The combination chemotherapy with cisplatin, bleomycin, vinblastine and cyclophosphamide is effective for initial treatment of childhood intracranial yolk sac tumor. It is necessary, however, to reevaluate the cisplatin dosage and treatment schedule in order to reduce such side effects as bone marrow suppression and renal damage.

The purpose of this study is to evaluate the antitumor activity of combination carboplatin and etoposide in measurable medulloblastoma. From January '89 to January '92, 26 patients with medulloblastoma were included in a multicentric phase II study of 2 courses of carboplatin 160 mg/m2/d day 1 to day 5 and VP16 100 mg/m2/d day 1 to day 5. Median age was 10 years (19 months-14.5 years). First treatment was surgery alone in 1 patient, surgery + radiotherapy in 4 patients, surgery + chemotherapy in 2 patients less than 3 years old, surgery + radiotherapy + chemotherapy in 19 patients ("8 drugs in 1 day" based:17, SIOP I:1, SIOP II:1). Previous treatment included cisplatin (20 cases), carboplatin (1 case), and VP16 (7 cases). Measurable disease was evaluated by CT scan,
MRI
or myelogram and CSF. Response rate (RR) was 72 +/- 10%:8 complete responses (CR), 10 partial responses (PR), 1 objective effect (OE), 6 progressive disease (PD), 1 non-evaluable. Thirty-six courses were evaluated for toxicity. Median duration of WHO grade 4
neutropenia
was 8 days (0-23). One patient died at day 18 after the first course because of diffuse haemorrhage during septic aplasia. Five other non-life-threatening septicemias were recorded. Median number of platelet transfusions was 1 (0-4). One child who had achieved a PR after two courses died from CNS bleeding after the third course. This drug combination achieves a high response rate in childhood medulloblastoma. Severe toxicity has been mainly encountered in previously heavily treated patients. Tolerance may be acceptable in newly diagnosed children, but careful hematological follow-up and platelet transfusional support are definitely mandatory.

12 patients: (7 males and 5 females) with recurrent brainstem gliomas were treated with the oral topoisomerase inhibitor VP-16 (Etoposide). Patients ranged in age from 3 to 49 years with a median age of 7 years. All patients had been previously treated with radiation therapy (conventional fractionation: 4; hyperfractionation: 8) and 5 had received prior nitrosourea-based chemotherapy at time of tumor recurrence. Tumor recurrence was documented by radiographic tumor enlargement utilizing brain
MRI
with gadolinium enhancement (12) and clinical neurologic deterioration (9). Two patients underwent biopsy pathologically documenting tumor recurrence. Each cycle of therapy consisted of 21 days of VP-16 (50 mg/m2/day) followed by a 14 day rest followed by an additional 21 days of VP-16 (50 mg/m2 day). Complete blood counts were followed bi-weekly and a neurologic examination and brain
MRI
scan with contrast were performed prior to initiation of each cycle of therapy. Treatment related complications included: partial alopecia (5); diarrhea (5); weight loss (4);
neutropenia
(2); and thrombocytopenia (4). No patient required transfusion or antibiotic treatment of neutropenic fever. There were no treatment related deaths. 12 patients were evaluable of whom 6 demonstrated a radiographic response (1 complete; 3 partial; 2 stable disease) with a median duration of response of 8 months. In summary; oral VP-16 is a well tolerated and relatively non-toxic chemotherapeutic agent with apparent activity in this small cohort of patients with recurrent brainstem gliomas.

A 28-year-old patient with acute lymphoblastic leukemia and
neutropenia
developed necrotizing enterocolitis and Clostridium septicum bacteremia, followed by rhabdomyolysis, skin rash, and acute neurologic changes. Numerous cortical leptomeningeal enhancements were present on head
MRI
. Meningeal and brain biopsy showed segmental, full-thickness lysis of smooth muscle cells of medium-sized meningeal vessels with overall preservation of the structure of the vessel wall.

Pre-clinical data and adult experience suggests that topoisomerase targeted anti-cancer agents may be highly schedule dependent, and efficacy may improve with prolonged exposure. To investigate this hypothesis, 28 children with recurrent brain and solid tumors were enrolled in a phase II study of oral etoposide (ETP). Patients were prescribed ETP at 50 mg/m2/ day for 21 consecutive days. Courses were repeated every 28 days pending bone marrow recovery. Evaluation of response was initially performed after 8 weeks and then every 12 weeks either by CT or
MRI
. Three of 4 patients with PNET (primitive neuroectodermal tumor)/medulloblastora achieved a partial response (PR). Two of 5 with ependymoma responded, one with a complete response and one with a PR. Toxicity was manageable with only 1 admission for fever and
neutropenia
in 120 cycles of therapy. Five patients had grade 3 or 4
neutropenia
. One had grade 4 thrombocytopenia and one grade 2 mucositis and withdrew as a result. One patient had grade 2 diarrhea. Two patients who achieved a PR had received ETP as part of prior combination chemotherapy regimens. Daily oral etoposide is active in recurrent PNET/medulloblastoma and ependymoma. Toxicity is manageable and rarely requires intervention. Daily oral etoposide in combination with crosslinking agents should be considered in future phase III trials. Determination of activity in glioma and solid tumors is not complete.

Hepatosplenic candidiasis following granulocytopenic periods is a relatively recently recognised problem in immunocompromised patients, particularly in those with acute leukaemia. We present three patients in whom diagnosis of hepatosplenic candidiasis was suspected on the basis of ultrasonographic (US), computed tomographic (CT) findings and confirmed by laparoscopy and biopsy of liver lesions. All three patients were successfully treated briefly with amphotericin B, followed by a longer period of fluconazole. In one patient laparotomy and surgical evacuation of abscesses was performed. This condition could be more often recognised by careful follow-up of liver function test, C-reactive protein level, ultrasonography, CT and
MRI
after recovery from chemotherapy-induced
neutropenia
.

In this study, the records of 17 adult patients with medulloblastoma treated with craniospinal radiation and 1 of 2 multiagent chemotherapy protocols were reviewed for progression-free survival, overall survival, and toxicity, and the patients were compared with each other and with similarly treated children and adults. Records of patients treated at 3 institutions were reviewed. Seventeen medulloblastoma patients (11 female, 6 male) with a median age of 23 years (range, 18-47 years) were treated with surgery, craniospinal radiation (CSRT) plus local boost, and 1 of 2 adjuvant chemotherapy regimens. All tumors were infratentorial (10 in 4th ventricle and 7 in left or right hemisphere). Ten patients presented with hydrocephalus, and 7 of them were shunted. Eight patients had gross total resection, 7 had subtotal resection (>50% removed), and 2 had partial resection (<50% removed). Postoperatively, 3 patients had positive cytology and 3 had positive spinal
MRI
. Five patients were classified as good risk and 12 were classified as poor risk (Chang staging system). Ten patients were treated with the "Packer protocol," consisting of CSRT plus weekly vincristine followed by 8 cycles of cisplatin, lomustine, and vincristine. Seven patients were treated with the Pediatric Oncology Group (POG) protocol, consisting of alternating courses of cisplatin/etoposide and cyclophosphamide/vincristine, followed by CSRT. Eight of 17 patients relapsed, with all 8 relapsing at the primary site. Other relapse sites included the leptomeninges (5), bone (1), and brain (1). The estimated median relapse-free survival (Kaplan-Meier) for all patients was 48 months (95% confidence interval, >26 months to infinity). Median relapse-free survival for patients on the Packer protocol was 26 months, and for those on the POG regimen was 48 months (P = 0.410). Five of 10 on the Packer protocol were relapse-free, while 4 of 7 were relapse-free on the POG regimen. Two patients relapsed during chemotherapy and 6 relapsed after completing all therapy at 18, 18, 26, 30, 40, and 48 months. The estimated median survival of all patients was 56 months (95% confidence interval, 27 to infinity) with 11 patients alive; for the Packer protocol, median survival was 36 months, and for the POG protocol, it was 57 months (P = 0.058). The hazard ratio was 0 (95% confidence interval, 0 to infinity). Toxicity during the Packer protocol was moderately severe, with only 1 of 10 patients able to complete all therapy. Two patients had severe abdominal pain during CSRT + vincristine, and 5 had peripheral neuropathy during vincristine therapy. Hearing loss (>20 dB) occurred in 7,
neutropenia
(<500 microl) in 6, thrombocytopenia (<50,000 microl) in 6, nephrotoxicity (>25% decrease by creatinine clearance) in 2, and decreased pulmonary function (diffusing capacity for carbon monoxide decrease >40%) in 1. On the POG protocol, only 1 patient had persistent nausea and vomiting, 2 had peripheral neuropathy, and 3 had hearing deficit (>20 dB) or tinnitus. The POG and Packer protocols did not have a statistically significant difference in relapse-free or overall survival because of the small sample size. The POG protocol seemed to have less nonhematologic toxicity. Adults on the Packer protocol appeared to have shorter median survival and greater toxicity than did children. To know whether adding adjuvant chemotherapy to craniospinal radiation in adult therapy increases relapse-free and overall survival, we must await the results of a larger randomized controlled clinical trial.

This is the first report that the combination of paclitaxel and cisplatin is feasible in a patient with recurrent ovarian cancer undergoing hemodialysis. Paclitaxel at a dose of 150 mg/m(2) was administered as a 3-h continuous i.v. infusion. Thirty minutes after paclitaxel administration, cisplatin was administered at a dose of 30 mg/m(2) for 30 min. Hemodialysis was started 30 min after completion of the cisplatin infusion and performed for 5 h. The maximum plasma concentrations of paclitaxel, total platinum and free platinum were 3.26, 2.44 and 1.84 microg/ml, respectively. The AUC of paclitaxel and free platinum were 15.3 and 1.76 microg x h/ml, respectively. The pelvic tumor size was reduced by 42% on
MRI
after the second course of this therapy. Grade IV
neutropenia
and grade III thrombopenia were observed. We conclude that paclitaxel and cisplatin combination chemotherapy is efficacious and feasible for an ovarian cancer patient under hemodialysis.

Docetaxel is an excellent agent with a high antitumor effect for advanced/recurrent head and neck cancer. A 67-year-old male with advanced hypopharyngeal cancer (T3N2bM1: Stage IV) underwent two courses of superselective intra-arterial infusion of docetaxel and intravenous administration of CDDP and 5-FU. Using a coaxial technique, a microcatheter was placed in the feeding artery. Using imaging techniques docetaxel (60 mg/body and 30 mg/body) was infused into the vessels. During chemotherapy the patient received concomitant radiotherapy (50 Gy).
MRI
after chemoradiation showed a complete response for the primary tumor and a partial response for the neck metastasis. Grade 4 leukopenia and
neutropenia
and grade 3 pharyngitis/esophagitis were observed during chemoradiotherapy, but these adverse effects abated immediately and were not critical. We conclude that this superselective intra-arterial infusion of docetaxel will be useful and safe for head and neck cancer.
