Purpose The advances in the treatment of retinoblastoma have enabled salvaging the globe in advanced stages with intra-arterial chemotherapy (IAC). We developed a strategy of alternate application of systemic intravenous chemotherapy (IVC) and IAC (referred to as alternate systemic IVC and IAC; ASIAC) to reduce central nervous metastases during IAC and examined its efficacy and safety in eye globe salvage in this study.
Materials and Methods Between January 2010 and February 2021, 43 eyes of 40 patients received ASIAC treatment for retinoblastoma at the Yonsei Cancer Center, Yonsei University Health System. Their medical records were reviewed retrospectively to evaluate the eye salvage rate (ESR), defined from diagnosis to enucleation. High-risk retinoblastoma was defined as group D or E by the International Classification of Retinoblastoma.
Results The study enrolled 38 and five cases of high-risk and low-risk retinoblastoma, respectively. In total, 178 IAC and 410 IVC courses were administered, with a median of 4 (interquartile range [IQR], 3.0 to 5.0) IAC and 9 (IQR, 6.0 to 11) IVC courses per eye, respectively. The 5-year ESR was 60.4%±8.7% for the whole cohort, 100% for low-risk retinoblastoma, and 53.6%±9.8% for high-risk retinoblastoma. Among those diagnosed since 2015, the 5-year ESR for high-risk retinoblastoma was 63.5%±14.0%. Fifteen eyes underwent enucleation; no viable tumor was found in three enucleated eyes. There were no deaths in this cohort.
Conclusion Primary IAC-IVC (i.e., ASIAC) for patients with retinoblastoma was tolerable and effective in salvaging the eye and maintaining survival.

PURPOSE Osteosarcoma is one of the most common juvenile malignant tumors in Korea. Combined modality treatment [pre-operative chemotherapy + surgery (limb salvage or amputation) + adjuvant chemotherapy] had improved the overall survival and quality of life. To improve the local control rate, we introduced pre-operative chemotherapy combined with intra-arterial (IA) cisplatin and continuous intravenous infusion (CI) of adriamycin. We evaluated the efficacy and feasibility, such as limb salvage rate, recurrence pattern and the survival impact, based on the histologic response of pre-operative chemotherapy. MATERIALS AND METHODS Fourty-one patients with histologically-proven high grade osteosarcoma of the extremities were enrolled from January 1990 to June 1996.
Pre-operative chemotherapy, cisplatin 120 mg/m2 IA and adriamycin 75 mg/m2/72hrs CI, was administered for 3 cycles with 3 week interval, followed by surgery. Post-operative chemotherapy was applied by the tumor necrosis rate. If the tumor necrosis of the specimen was more than 90%, the same regimen af the preoperative one was administered for 3 cycles. A salvage regimen (Ifosfamide 7.5 gm/m2/5d IV + high dose MTX 10 gm/m2 IV VP-16 360 mg/m2/3d IV) was administered every 3 weeks for 6 cycles if the tumor necrosis was <90%. RESULTS Of 41 patients, 37 were evaluable for efficacy and toxicities, because 4 refused further chemotherapy after 1 or 2 cycles. Twenty-one patients were male and 16 female, with the median age of 16 years (8-41). The tumor locations were as follows: distal femur 20, proximal tibia 8, humerus 6, distal tibia 2 and 1 in proximal femur. All but one patient, who died of neutropenic sepsis, completed the planned pre-operative therapy. Of the 36 patients who received surgery, limb salvage surgery was possible in 30 patients (83.3%) and 27 patients (75%) showed a good response (10 with grade III, 27.8%; 17 with grade IV, 47.2%). With a median follow-up of 23 months, 3-year disease-free survival rate was 54.7% and overall survival rate was 78.3%. Of the 15 patients who recurred, the major metastatic site was the lungs. No operation-related mortality was observed. Most patients experienced grade III-IV nausea, vomiting and hematologic toxicities, which were reversible with supportive care. CONCLUSION Pre-operative chemotherapy combined with IA cisplatin and CI adriamycin induced higher good response rate without survival benefits. To improve the survival rate, the design of good salvage chemotherapy with a non-cross resistant regimen should be considered.
