Metastatic esophageal carcinoma to the eye masquerading as inflammatory vitreo-retinitis: A case report and literature review.

We report an unusual case of metastatic esophageal carcinoma to the vitreous associated with focal retinitis in a 44-year-old male. A 44-year-old male patient, known case of locally advanced esophageal carcinoma, presented with a 3-day history of left eye floaters. The initial diagnosis was inflammatory vitreo-retinitis that responded to systemic steroids. Four months later, the patient presented with relapsed intraocular inflammation, vitreous biopsy using a 25G needle was performed, and cytology confirmed the presence of metastatic carcinoma consistent with his primary esophageal cancer. The patient received external beam radiotherapy to his ocular and brain metastasis, and his eye examination was stable. Five months later, the patient passed away due to progressive brain metastasis.

Outcomes of Pediatric Patients With Metastatic Ewing Sarcoma Treated With Interval Compression.

BACKGROUND: Interval compression (IC), a regimen of alternating vincristine/doxorubicin/cyclophosphamide and ifosfamide/etoposide every 2 weeks, improves survival for localized Ewing sarcoma (ES), with uncertain effect on metastatic disease. MATERIALS AND METHODS: We reviewed the charts of pediatric patients with metastatic ES treated with IC at our center between January 2013 and March 2020. We calculated event-free survival and overall survival (OS) and used log-rank tests for univariate comparisons. RESULTS: We identified 34 patients 2.7 to 17.1 years of age (median: 11.6 y). Twenty-six patients (76%) had pulmonary metastases, and 14 (41%) had extrapulmonary metastases. All patients received local control therapy: surgery only (n=7, 21%), radiotherapy only (n=18, 53%), or both (n=9, 26%). The estimated 3-year OS and event-free survival were 62%±9% and 39%±9%, respectively. Patients with pulmonary-only and extrapulmonary metastasis had a 3-year OS of 88%±8% and 27%±13%, respectively ( P =0.0074). Age group (above vs. below 12 y), or primary tumor site did not affect survival, but local control therapy did (surgery only, 83%±15%; combined surgery and radiation, 30%±18%; radiation only, 15%±10%; P =0.048). CONCLUSION: IC yielded similar outcomes for patients with metastatic ES to other reported regimens. We suggest including this approach to other blocks of therapy.

Impact of Adjuvant Radiotherapy in Patients with Central Neurocytoma: A Multicentric International Analysis.

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.
