Background: Breast cancer remains a leading cause of cancer-related mortality and morbidity worldwide. Ocular and periocular metastasis present as a rare but clinically significant manifestation. This study aims to explore demographics and clinical aspects of ocular and periocular metastasis in breast cancer patients. Methods: A retrospective cohort study comprising 45 breast cancer patients with ocular or periocular metastasis treated between 2013 and 2023. Patient demographics, tumor characteristics, diagnostic methods, treatment modalities, visual outcomes, and survival data were analyzed. Results: Among 9902 breast cancer patients, 0.5% developed ocular or periocular metastasis, constituting 2.4% of metastatic cases. The median age was 50 years. Ocular metastasis timing varied: 5% before breast cancer, 24% concurrent, 22% within a year, and 49% after. The most common presentations included incidental MRI findings (42%) and vision decline (31%). Metastasis involved the orbit (47%), choroid (40%), optic nerve (11%), and iris (2%), with 44% having bilateral involvement. Predictive factors included invasive lobular carcinoma (ILC) (p < 0.0001) and brain metastasis (p < 0.0001), with ILC exhibiting a sixfold higher likelihood of ocular metastasis than invasive ductal carcinoma (IDC). Primary treatment was radiation therapy (89%), yielding a 55% maintenance of excellent vision (<0.5), with 93% developing dry eye disease. Patients with ocular metastasis faced an increased risk of disease-related mortality (p < 0.0001), with 71% succumbing within 10 months post-diagnosis. Conclusions: Ocular metastasis in breast cancer is rare (0.5%) but signifies poor outcome. It is linked to ILC and concurrent brain metastasis. Primary treatment involves radiation therapy, with a favorable visual prognosis.

Background: Central neurocytoma (CN) is a rare tumor accounting for <0.5% of all intracranial tumors. Surgery ± radiotherapy is the mainstay treatment. This international multicentric study aims to evaluate the outcomes of CNs patients after multimodal therapies and identify predictive factors. Patients and methods: We retrospectively identified 33 patients with CN treated between 2005 and 2019. Treatment characteristics and outcomes were assessed. Results: All patients with CN underwent surgical resection. Radiotherapy was delivered in 19 patients. The median radiation dose was 54 Gy (range, 50–60 Gy). The median follow-up time was 56 months. The 5-year OS and 5-year PFS were 90% and 76%, respectively. Patients who received radiotherapy had a significantly longer PFS than patients without RT (p = 0.004) and a trend towards longer OS. In addition, complete response after treatments was associated with longer PFS (p = 0.07). Conclusions: Using RT seems to be associated with longer survival rates with an acceptable toxicity profile.

The number of cancer survivors and survivorship are increasing. Health-related quality of life (HRQOL) has not been widely studied in low-and-middle-income countries (LMICs). The aim of this study is to explore HRQOL of childhood brain tumor survivors and its determinants in Jordan. Health-related quality of life information was collected from 80 patients treated at the King Hussein Cancer Center and their parents using the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales questionnaire in Arabic. Multivariable linear OLS regression models were used to analyze correlates of HRQOL and compare differences between child- and parent-reported responses. Health-related quality of life scores reported by survivors and by parents were positively correlated on all subscales and total PedsQL scores (r = 0.59, P = .001). Survivors reported better HRQOL in cognitive subscale (β = 0.56, P = .03) and worse HRQOL in work subscale (β = 0.43, P = .04), but no significant differences in the physical, emotional, and social subscales and total PedsQL scores. Significant predictors of HRQOL reported by parents and by children were different. Supratentorial tumor location was associated with a 10.97-unit lower physical HRQOL score, and recurrence of tumors predicted a 17.5-unit lower total HRQOL score, indicating worse quality of life. Male gender (β = 14.9, P = .002) and diagnosis of hypopituitarism (β = 16.1, P = .03) were associated with better HRQOL. Furthermore, patients that only had radiotherapy treatment had better emotional HRQOL (β = 32.9, P = .006) compared to patients that had combined radiotherapy and chemotherapy. This study provides evidence on determinants of HRQOL of pediatric brain tumor patients in Jordan. Future studies need to capitalize on the findings of this study to institute a system for regular assessment of quality of life of pediatric cancer patients in Jordan and other countries with similar health care systems and sociocultural backgrounds.

Background and Objectives: Primary central nervous system (CNS) tumors are often associated with relatively poor outcomes. Data on the epidemiology and outcome of CNS tumors in Jordan are scarce. We aim to report the epidemiology and outcome of primary CNS tumors of patients managed at a comprehensive cancer care center in Jordan. Methods: We performed a retrospective chart review of all Jordanian patients with a primary CNS tumor diagnosis who were managed at the center between July 2003 and June 2019. We included all entities described in the 2021 CNS WHO classification system, in addition to pituitary neuroendocrine tumors (PitNETs). We used the Kaplan–Meier method to estimate the 1-year, 2-year, and 5-year overall survival (OS) rates for each entity. Results and Findings: We included 2094 cases. The numbers of pediatrics and adults were 652 (31.1%) and 1442 (68.9%), respectively. The three most common groups of tumors were “gliomas, glioneuronal tumors, and neuronal tumors” (n = 1200 [57.30%]), followed by meningiomas (n = 261 [12.5%]), embryonal tumors (n = 234 [11.2%]). The three most common tumor families were adult-type diffuse gliomas (n = 709 [33.8%]), medulloblastoma (n = 199 [9.5%]), and circumscribed astrocytic gliomas (n = 183 [8.7%]). The median survival for the entire cohort was 97 months (95CI; 81–112). Survival was significantly worse for males and adults compared to their respective counterparts. Among the most common tumor group, “gliomas, glioneuronal tumors, and neuronal tumors”, OS rates for adult-type diffuse gliomas were significantly lower than all other types. Overall, adult gliomas with IDH-mutations had a survival advantage over wildtype cases (IDH-mutant 1-year OS, 89% [82–97%] vs. IDH-wildtype 1-year OS, 60% [52–70%]; p < 0.001). Conclusions: We present a detailed analysis of the primary CNS tumors diagnosed in the largest cancer center in Jordan between 2003 and 2019. We compared the epidemiology and overall survival of these patients to worldwide estimates and found the epidemiology and outcome of these tumors comparable to worldwide trends.

Background: An inferior vena cava thrombus (IVCT) occurs in approximately 4–10% of Wilms tumor (WT) cases. The presence of an IVCT complicates surgical management and potentially affects patient outcomes. We reviewed all patients with a WT with and without an IVCT treated at our center, comparing their characteristics and outcome. Patients and Methods: We retrospectively reviewed pediatric patients with a WT treated between November 2014 and July 2023. Patients were categorized according to the presence or absence of an IVCT. Data on demographics, clinical presentation, imaging findings, treatment modalities, and outcomes were collected. Group comparisons for categorical data were carried out using Chi-square tests, Event-free survival (EFS) and overall survival (OS) were estimated using Kaplan–Meier curves, and differences between groups were assessed with the log-rank test. Results: Among 110 children with a unilateral WT, 17 (15.4%) had an IVCT at presentation. Their median age at diagnosis was 4.2 years. Females predominated (65%) and 11 (65%) had distant metastasis. Thrombus levels were infra-hepatic (52.9%), retro-hepatic (23.6%), supra-hepatic (5.9%), and intra-cardiac (17.6%). Thrombus resolution following neo-adjuvant chemotherapy was achieved in 41.2% of patients, most frequently in infra-hepatic thrombi. Local control followed neo-adjuvant chemotherapy that included doxorubicin. Favorable histology was observed in 70% of patients with an IVCT. Compared with patients without an IVCT, children with an IVCT tend to present at an older age, have hematuria, a larger tumor, positive lymph node (LN) involvement, and metastatic disease (p value, 0.019, 0.008, 0.01, 0.014, and 0.002, respectively). On univariable analysis, older age, the presence of metastatic disease, IVCT, LN involvement, and diffuse anaplasia were associated with inferior EFS and OS. Five-year EFS and OS were significantly lower in patients with IVCT compared to those without (51% ± 12.5% vs. 74.5% ± 4.6%, p = 0.021 and 53.8% ± 15.4% vs. 82% ± 4.9%, p = 0.012, respectively). Conclusions: We observed a higher proportion of IVCT than previously reported. Consistent with prior studies, an IVCT was associated with more aggressive disease features. Although survival was worse in patients with an IVCT, the mere presence of a thrombus as an independent prognostic factor requires evaluation in larger patient cohorts.
