PURPOSE: We investigated the effectiveness and safety of DA-3030 for prophylatic use in patients receiving chemotherapy for malignant disease. MATERIALS AND METHODS: Seventy cancer patients were randomized to receive chemotherapy alone (36 patients) or with DA-3030 administered (34 patients) after stratified block randomization according to chemotherapeutic regimen. DA-3030 was subcutaneously administered at the dose of 100 pg/m/day for 10 days from 24 hours after the completion of chemotherapy. RESULTS: Of the 70 enrolled patients, 62 patients were evaluable. The neutropenia (absolute neutrophil count [ANC] <1,000/mm) occurred in 9 of 32 (28.1%) of the DA-3030 group and 21 of 30 (90.0%) of the control group, giving relative risk for control group of 0.154 (95% confidence interval [CI], 0.05 to 0.45; p-0.0001). Severe neutropenia (ANC 500/mm') occurred in 4 of 32 (12.5%) of the DA-3030 group and in 20 of 30 (66.7%) of the control group (relative risk for control group of 0.316 [95% CI, 0,18 to 0.55]; p=0.0001). The mean duration of neutropenic period (+/-standard error) was 1.13+/-0.34 days in the DA-3030 group and 6.73+/-0.69 days in the control group respectively, and was significantly shorter in the DA-3030 group (p<0.0001). And, there was higher nadir ANC in the OA-3030 group than that in the control group (p=0.0001); the mean nadir ANC was 2,547+/- 343/mm and 442+/-120/mm, respectively. The DA-3030 group had significantly higher incidence of myalgia in comparison to the control group (43.8% compared with 3.3%; p=0.001). However, it was tolerable and was easily managed by conservative therapy CONCLUSION: The use of DA-3030 was effective in preventing chemotherapy-induced neutropenia.

PURPOSE: To see the relationship between the response to chemotherapy and the final outcome of neoadjuvant chemotherapy and radiotherapy in patients with locally advanced hypopharyngeal cancer. METHODS AND MATERIALS: A retrospective analysis was done for thirty-two patients with locally advanced hypopharyngeal cancer treated in the Seoul National University Hospital with neoadjuvant chemotherapy and radiotherapy from August 1979 to July 1997. The patients were treated with Co-60 teletherapy unit or 4MV or 6MV photon beam produced by linear accelerator. Daily fractionation was 1.75 to 2 Gy, delivered five times a week. Total dose ranged from 60.8 Gy to 73.8 Gy. Twenty-nine patients received continuous infusion of cisplatin and 5-FU. Other patients were treated with cisplatin combined with bleomycin or vinblastin. Twenty-four (75%) patients received all three prescribed cycles of chemotherapy delivered three weeks apart. Six patients received two cycles, and two patients received only one cycle. RESULTS: The overall 2-year and 5-year survival rates are 65.6% and 43.0%, respectively. 5-year local control rate is 34%. Organ preservation for more than five years is achieved in 12 patients (38%). After neoadjuvant chemotherapy, 24 patients achieved more than partial remission (PR); the response rate was 75% (24/32). Five patients had complete remission (CR), 19 patients PR, and 8 patients no response (NR). Among the 19 patients who had PR to chemotherapy, 8 patients achieved CR after radiotherapy. Among the 8 non-responders to chemotherapy, 2 patients achieved CR, and 6 patients achieved PR after radiotherapy. There was no non-responder after radiotherapy. The overall survival rates were 60% for CR to chemotherapy group, 35.1% for PR to chemotherapy group, and 50% for NR to chemotherapy group, respectively ( p=0.93). There were significant difference in five-year overall survival rates between the patients with CR and PR after neoadjuvant chemotherapy and radiotherapy (73.3% vs. 14.7%, p< 0.01). The prognostic factor affecting overall survival was the response to overall treatment (CR vs. PR, p<0.01). CONCLUSION: In this study, there were only five patients who achieved CR after neoadjuvant chemotherapy. Therefore the difference of overall survival rates between CR and PR to chemotherapy group was not statistically significant. Only the response to chemo-radiotherapy was the most important prognostic factor. There needs to be more effort to improve CR rate of neoadjuvant chemotherapy and consideration for future use of concurrent chemoradiotherapy.

The authors report a case of syringo-pleural shunt for recurrent distal obstruction of syringosubarachnoid shunt in a 23-year-old woman. She complained of tingling sensation and dysesthesia on the left upper extremity. Neuroradiologic imaging studies revealed syringomyelia in the left lateral side of the cord from medulla to 7th thoracic cord level. We identified intraoperatively high internal pressure of the syrinx cavity due to distal shunt tube obstruction. Syringo-pleural shunt was performed and cavity size was markedly decreased at later follow up MRI. In conclusion, the posttraumatic syrinx, especially in cases with previous syringosubarachnoid shunt or diffuse subarachnoid scarring, can be successfully managed with syringo-pleural shunt.

PURPOSE: The purpose of this study was to assess the clinical outcomes of hypofractionated radiotherapy (HFRT) with three-dimensional conformal technique for medically inoperable patients with early stage non-small-cell lung cancer (NSCLC) and to evaluate prognostic factors. MATERIALS AND METHODS: We performed a retrospective review of 26 patients who underwent HFRT for early stage NSCLC between September 2005 and August 2011. Only clinical stage T1-3N0 was included. The median RT dose was 70 Gy (range, 60 to 72 Gy) and the median biologically equivalent dose (BED) was 94.5 Gy (range, 78.0 to 100.8 Gy). In 84.6% of patients, 4 Gy per fraction was used. Neoadjuvant chemotherapy with paclitaxel and cisplatin was given to 2 of 26 patients. RESULTS: The median follow-up time for surviving patients was 21 months (range, 13 to 49 months). The overall response rate was 53.9%, and the initial local control rate was 100%. The median survival duration was 27.8 months. Rates of 2-year overall survival, progression-free survival (PFS), local control (LC), and locoregional-free survival (LRFS) were 54.3%, 61.1%, 74.6%, and 61.9%, respectively. Multivariate analysis showed that BED (>90 vs. < or =90 Gy) was an independent prognostic factor influencing PFS, LC, and LRFS. Severe toxicities over grade 3 were not observed. CONCLUSION: Radical HFRT can yield satisfactory disease control with acceptable rates of toxicities in medically inoperable patients with early stage NSCLC. HFRT is a viable alternative for clinics and patients ineligible for stereotactic ablative radiotherapy. BED over 90 Gy and 4 Gy per fraction might be appropriate for HFRT.

Journal of Korean Neurosurgical Society 2002;31(4):305-310
OBJECTIVE: Previous standard surgical approaches for aneurysms of anterior circulation are concerned with possible injury to the normal brain by cerebral retraction. Simplified skull base approaches have been introduced to fulfill the ideal goals of skull base surgery, brain protection and technical minimalism. Superolateral orbital craniotomy and orbital roof craniotomy via eyebrow incision offered sufficient working space for aneurysmal neck clipping of anterior circulaton and have advantages of minimal brain retraction and rapid recovery. METHODS: The concept and technique of the superolateral orbital craniotomy and orbital roof craniotomy are presented in detail. We conducted a retrospective study in which we evaluated the technical aspect of the superolateral orbital craniotomy and orbital roof craniotomy considering the indications, limitations, and complications of these approaches. RESULTS: The superolateral orbital craniotomy and orbital roof craniotomy provide an ample space to access the neurovascular structure of the anterior skull base without using brain retractors, enable rapid anatomical reconstruction for closure and acceptable cosmetic results. CONCLUSION: The superolateral orbital craniotomy and orbital roof craniotomy via eyebrow incision offer better surgical possibilities and approach related morbidity than conventional approaches in the treatment of anterior circulation aneurysms.
