    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Studies conducted in recent years have reported promising results regarding the treatment of retinoblastoma with the intra-arterial use of melphalan. In the present study, we intended to report the results of intra-arterial chemotherapy with melphalan (IACT) in the treatment of newly diagnosed or relapsed-refractory retinoblastoma patients at the Department of Pediatric Oncology of Hacettepe University, Ankara, Turkey. 〈 b 〉 〈 i 〉 Materials and Methods: 〈 /i 〉 〈 /b 〉 This was a retrospective study of patients with intraocular retinoblastoma who were treated with IACT from December 2011 to May 2014. A total of 56 eyes of 46 consecutive patients (30 males and 16 females) were included in the study. Forty-four eyes received systemic chemotherapy upon diagnosis (systemic chemotherapy group, SCG), and 12 eyes were those of newly diagnosed patients (primary intra-arterial melphalan group, PIAG). The choice of the IACT dose was based on age. Tumor control and globe salvage with IACT were analyzed. Complete blood counts were examined 7 days after the IACT for systemic toxicity. Ocular toxicities such as proptosis, eyelid edema, ocular motility, and retinal and optic atrophy were assessed by an ocular oncologist with regular ophthalmologic examinations. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Enucleation was avoided overall in 66% (37/56) of the eyes, including 75% (9/12) in the PIAG and 64% (28/44) in the SCG patients. The 1-year enucleation-free survival rate was 56.7% at a median follow-up time of 11.9 months (range 0.27-27.6). IACT was administered in a total of 124 cycles (ranging from 1 to 7 cycles, mean 2.3). The responses were as follows: regression of the retinal tumor in 27 eyes and improvements in vitreous seeding in 5 of 15 eyes. The further treatment requirements after IACT were as follows: enucleation in 19 eyes (10 with vitreous seeding), radiotherapy in 3 eyes, systemic chemotherapy in 1 eye, and local therapy in 1 eye. No severe systemic side effects occurred. Transient swelling of the eyelids (22 patients), conjunctival chemosis (12 patients), upper eyelid ptosis (5 patients), redness over the frontal area (3 patients), limitation of ocular motility (3 patients) and mild proptosis (1 patient) were detected. Retinal pigment epithelial alterations (30 patients) and optic atrophy (3 patients) were seen in the late follow-up. 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 Globe salvage and avoidance of radiotherapy may be achieved by IACT with limited toxicity. This treatment is efficient, repeatable and safe.

    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 Almost half of the cystic renal lesions are still overdiagnosed and overtreated. New clinical and radiological parameters are needed to distinguish the malignant Bosniak 3 lesions from the benign ones. We aimed to evaluate the clinical and radiological parameters that may be related to malignancy risk for Bosniak category 3 renal cysts. 〈 b 〉 〈 i 〉 Materials and Methods: 〈 /i 〉 〈 /b 〉 Patients who underwent surgical resection of a histopathologically confirmed Bosniak 3 renal cyst between March 2007 and September 2019 were evaluated. Two experienced uro-radiologists have reevaluated the last preoperative computed tomography and/or MRI images of the patients and reclassified the lesions according to the Bosniak classification. They also reported cystic features such as nodularity, septation, focal thickening, enhancement, and calcification. Clinical, pathological, and oncological outcomes were recorded. Then patients were divided into 2 groups as Group 1 (benign pathology) and Group 2 (malignant pathology) according to final histopathological report. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 A total of 79 patients were included in this study. Mean follow-up time was 47 ± 34 months. There were 30 patients in Group 1 and 49 patients in Group 2. Hypertension ( 〈 i 〉 p 〈 /i 〉 = 0.001) and smoking history ( 〈 i 〉 p 〈 /i 〉 = 0.008) were more common in malignant group. Among the radiological findings, lower tumor diameter ( 〈 i 〉 p 〈 /i 〉 = 0.024), presence of cyst wall enhancement ( 〈 i 〉 p 〈 /i 〉 = 0.025), presence of nodularity ( 〈 i 〉 p 〈 /i 〉 = 0.002), and presence of focal thickening ( 〈 i 〉 p 〈 /i 〉 = 0.031) were found to be statistically significant for malignancy. Most of the tumors were at pathological T1 stage and Fuhrmann Grade 1–2. Only nodularity was found to be independent predictive factor for malignancy in multivariate analysis. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Clinical factors including hypertension and smoking, radiological factors including lower lesion size, cyst wall enhancement, nodularity, and focal thickening were predictors for malignancy of Bosniak 3 cysts.
