PURPOSE: Radiotherapy is effective in local treatment for retinoblastoma. However, asymmetric facial hypoplasia after radiation is a serious late effect. This study was performed to investigate the effects of enucleation and chemotherapy with or without radiotherapy in advanced intraocular and intraorbital retinoblastoma. METHODS: Between 1985 October and 2006 December, the records of thirty five patients who were diagnosed as retinoblastoma at Yeungnam University Hospital were reviewed. Advanced intraocular and intraorbital retinoblastoma patients classified as Reese-Ellsworth group III, IV, and V and Grabowski- Abramson class II were selected for the study. RESULTS: Eighteen patients were enrolled in this study. All patients were enucleated and had received chemotherapy. Nine patients received radiotherapy and nine patients didn't receive radiotherapy. Tumor cells were found on resection margin of optic nerve in five of nine patients who received radiotherapy, but none of nine who didn't receive radiotherapy. Chemotherapy included vincristine, adriamycin, cyclophosphamide, VM-26, cisplatin before 2001, and vincristine, etoposide, and carboplatin after 2001. There were no recurrences or metastases in nine patients who didn't receive radiotherapy. But two of nine patients who received radiotherapy had metastases to brain. However, all survivors who received radiotherapy had significant facial asymmetry. CONCLUSION: In advanced intraocular and intraorbital retinoblastoma without tumor cell on resection margin of optic nerve, enucleation and chemotherapy without local radiotherapy appears to be safe for long-term survival. However, in those with tumor cells on resection margin of optic nerve, enucleation and chemotherapy with local radiotherapy seems to be necessary to improve survival.

A case of dento-maxillofacial abnormality involving a 10-year-old male patient with a history of esthesioneuroblastoma is presented. This patient had been treated with 54 Gy (60)Co-gamma-radiation to the nasal cavity for 6 weeks and 6 cycles of combination chemotherapy of Cyclophosphamide, Cisplatin, Adriamycin, VM-26 (Teniposide), and DTIC (Dacarbazine) when he was 16 months of age. Five years after cessation of cancer therapy, he was disease free and transferred for extensive dental care to Kyung Hee University Dental Hospital. A clinical and radiologic follow-up over last 4 years showed root stunting, premature closure of the root apices, microdontia, developmental arrest, small crowns, and partial anodontia. Maxillofacial morphology evaluated by cephalometric analysis showed deficiency of maxillary development.

OBJECTIVETo investigate the antitumor effectiveness of teniposide in oral squamous cell carcinomas (OSCC) and to find evidence for using teniposide for treatment of patients with OSCC.
METHODSSeventy-five patients with OSCC from the School of Stomatology, Shanghai Second medical University during 1999 to 2001 were evaluated. Tumors were diagnosed pathologically, and drug sensitivity tested. The antitumor drugs tested were cisplatin (CDDP) and teniposide (VM-26). Fresh drug was diluted in complete medium at fold of five times of peak plasma concentration (PPC x 5) achieved by intravenous administration of clinical doses. The concentrations were VM-26 60 mg/L, CDDP 15 mg/L.
RESULTSThe MTT assay was performed in 75 of 81 patients (success rate 92.6%). The clinical stages of the 75 patients according to the UICC TNM classification of malignant tumors were 28 with stage IV, 34 with stage III, 11 with stage II and 2 with stage I. The pathological grades of the 75 patients according to three step classification were 18 with Grade I, 37 with Grade I approximately II and 20 with Grade III. At a drug concentration of PPC x 5, the inhibition rates of tumor cells for VM-26 and CDDP were 63.34% and 24.08%, respectively. The inhibition rates of tumor cells for VM-26 were significantly higher than those for CDDP (P < 0.01).
CONCLUSIONSThe inhibition rates of OSCC cells for VM-26 are significantly higher than for CDDP. VM-26 may be the first selected drug for treating patients with OSCC.

OBJECTIVETo explore the effect of antisense oligodeoxynucleotide (ASODN) of survivin gene on apoptosis and chemotherapy sensitivity of lymphoma cell line Raji.
METHODSAnti-survivin phosphorothioate ASODN was synthesized and transfected into Raji cells by lipofectin. MTT assay was used to detect cytotoxicity. Apoptosis was observed by fluorescence microscopy and flow cytometry. Survivin expression was determined by RT-PCR and Western-blotting.
RESULTS(1) survivin ASODN inhibited the cells proliferation in a dose and time dependent manner. (2) A higher apoptosis rate (33.0%) could be induced in Raji cells by survivin ASODN as compared with that induced by the sense oligodeoxynucleotide (11.5%) (P < 0.05). (3) The expression of survivin mRNA and protein significantly decreased after treatment with survivin ASODN. (4) There was a significant increase of cell inhibition rate after exposure to the combination of survivin ASODN and Vm26 as compared to Vm26 or survivin ASODN alone (both P < 0.05).
CONCLUSIONSurvivin ASODN is able to inhibit the proliferation of Raji cells, induce the apoptosis, and enhance the sensitivity of Raji cell to chemotherapy via specific down-regulation of survivin expression.

OBJECTIVETo compare the clinical efficacy and toxicity of teniposide (VM26) of higher dose with those of lower dose, both combined with cisplatin (CDDP) and pingyangmycin (PYM), in the treatment of patients with squamous cell carcinoma of oral and maxillofacial region (SCCOMR).
METHODSSixty-five patients with SCCOMR entered into this study prospectively. Thirty-three patients were treated with higher dose of VM26 (total dose was 320 mg) combined with CDDP and PYM (PTP1), the other thirty-two patients were treated with lower dose (total dose was 158 mg) of VM26 combined with CDDP and PYM (PTP2).
RESULTSThirty-three patients received a total of 38 cycles of PTP1. The overall response rate was 81.82% (27/33). Thirty-two patients received a total of 36 cycles of PTP2 and showed overall response rate by 81.25% (26/32). There was no significant difference between PTP1 and PTP2 groups in response rate (P > 0.05). But the blood toxicity was more severe in PTP1 group than in PTP2 group (P < 0.01). Bone marrow depression rate (1-4 stage) was 48.48% in PTP1 group versus 25.00% in the other group.
CONCLUSIONSA high response rate of 81.25% and relatively slighter adverse events could be obtained for lower dose of VM26 combined with CDDP and PYM (PTP2). So, the chemotherapy schedule, PTP2, a novel teniposide based regimen in SCCOMR could be employed and spread in clinical practice.

OBJECTIVETo compare the therapeutic efficacy of two regimens of postoperative radiotherapy with concurrent chemotherapy using temozolomide (TMZ) and teniposide (VM-26) plus semustine (Me-CCNU) in adult patients with grade III-IV cerebral gliomas.
METHODSNinety-six adult postoperative patients with grade III-IV cerebral gliomas were randomized into two groups (n=48) to receive 60 Gy radiotherapy with concurrent TMZ treatment (TMZ-RT group) and radiotherapy with VM-26 plus Me-CCNU treatments (VM-RT group). The adverse effects of marrow depression, gastrointestinal toxicity and acute radiation-induced brain injury were observed. The immediate effect and survival outcome of the patients were compared between the two groups.
RESULTSNo adverse effects beyond grade III were observed in the two groups. TMZ-RT group showed a significantly lower incidence of grade I-II adverse effects than VM-RT group (P<0.05). The median survival time and 1-, 2-, and 3-year survival rates of the patients in TMZ-RT group were 28 months, 72.9%, 54.2% and 31.3%, respectively, showing significant differences from those in VM-RT group (16 months, 62.5%, 33.3% and 16.7%, respectively, P<0.05).
CONCLUSIONRadiotherapy with concurrent TMZ chemotherapy is an effective regimen with mild toxicities for treatment of adult malignant cerebral glioma.

BACKGROUND: The prognosis for children with relapsed acute lymphoblastic leukemia remains dismal. Ifosfamide has previously been shown to be active as a single agent and in combination with doxorubicin, etoposide, and teniposide in pediatric solid tumors, recurrent acute lymphoblastic leukemia and adult acute leukemia. We assessed the efficacy and the toxicity of the drug combination with ifosfamide and etoposide in patients with relapsed refractory acute lymphoblastic leukemia. METHODS: Between April 1995 and May 1996, twenty children aged 1 to 14 years with ALL in Catholic Medical Center, all heavily pretreated and in bone marrow relapse, were enrolled in this study. Drugs were given intravenously each day for 5 days at the following doses ; ifosfamide 1.8 g/m2/day, etoposide 100 mg/m2/day and mesna 1440 mg/ m2/day(as a uroprotectant) ; Cycles were repeated every 28 days for two cycles. RESULTS: 1) Twenty heavily pretreated patients were entered on study. At study entry, seventeen patients were in first relapse, two were in second relapse and one was in third relapse. 2) Six patients(30%) achieved complete remission, and eight patients(40%) achieved partial remission. Overall response rate was 70%. 3) Duration of remission ranged from 30 days to 230 days. 4) The toxicity of the regimen was tolerated. Moderate or severe toxicity evaluated on a per cycle basis included : neutropenia 52.5%, thrombocytopenia 45%, hemorrhagic cystitis 12.5% and mucositis 2.5%. 5) Two patients went on to bone marrow transplantation with histocompatibility matched sibling donors while in remission. CONCLUSION: The combination of ifosfamide and etoposide with mesna uroprotection has significant activity in relapsed refractory childhood lymphoblastic leukemia with tolerable toxicity. We recommended bone marrow transplantation after successful reinduction because of short remission duration of this regimen.

Neuroblastoma is the most common extracranial solid tumor of childhood which presents various clinical symptoms depending on the primary and metastatic sites. However, it has been rarely reported that sudden onset of blindness was the chief complaint of neuroblastoma. A four years old boy was admitted to the Yeungnam University Hospital with the chief complaint of a sudden onset of blindness due to a distant metastasis of abdominal neuroblastoma to the sphenoid sinus. On admission, both side pupils were dilated without light reflex, fundoscopy showed pale optic disk, electroretinogram was subnormal and visual evoked potential showed no response. The liver was palpable in 3 ½ finger breadth from the right costal margin and adult fist sized mass was palpable in the right flank. Skull X-ray showed destructed sphenoid bone and clinoid process and brain CT scan showed tumor mass in the sphenoid sinus and left orbit. Ultrasonogram and CT scan of the abdomen showed large tumor masses around the right kidney and para-aortic and retropancreatic lymph node. IVP showed displaced right calyceal system with preserved contour. Left supraclavicular lymph node which appeared after admission was biopsied and it showed poorly differentiated neuroblasts. He was treated according to the multiagent chemotherapy schedule for stage IV neuroblastoma patient of children's cancer study group. Abdominal tumor masses and sphenoid sinus mass were markedly reduced after 2 courses of the combination chemotherapy of cyclophosphamide, vincristine, DTIC, adriamycin and VM-26. Eventhough the blindness was not improved, the patient has been in good clinical codition.

OBJECTIVETo evaluate the clinical characteristics, reasonable mode of treatment and prognostic factors in patients with primary central nervous system lymphoma (PCNSL).
METHODSTwenty-eight patients with PCNSL treated from 1989 to 2002 were retrospectively reviewed. The clinical characteristics, results of treatment and prognostic factors were analyzed by SPSS10.0 statistic software.
RESULTSOf 28 patients, 18 men and 10 women with a median age of 52 years. The median survival time was 2 years (range 6 months-6 years). The 5-year survival rate was 21.4%. Nineteen patients had single-locus lesion and 9 multi-locus lesion, 78.6% of the patients were diagnosed as having B-cell origin, its main type being diffuse large cell lymphoma. According to international working formulation (WF), moderate-grade of histopathology was observed in 57.7% (15/28). Cox regression analysis revealed that single- or multi-locus lesion was only independent prognostic factor (P = 0.0417). Combined chemotherapy showed significant efficacy for those patients who had lesion of B-cell origin, high grade or multi-locus lesion, and the efficacy of irregular chemotherapy was better than that of regular chemotherapy.
CONCLUSIONPrimary central nervous system lymphoma has a special prognostic factor. Chemotherapy plays a very important role in comprehensive treatment, irregular chemotherapy should be adopted as a regular treatment.
