Breast Carcinoma Metastasis to the Medial Rectus Muscle: Case Report

A 63-year-old woman with metastatic breast carcinoma presented to the ophthalmology clinic with diplopia and right abduction deficit. Magnetic resonance imaging showed isolated enlargement of the right medial rectus muscle. Biopsy of the enlarged muscle revealed metastasis of breast carcinoma. Ocular motility deficit in a patient with breast carcinoma should raise suspicion of metastasis to the orbit involving the extraocular muscles. Orbital imaging and biopsy are necessary for diagnosis and appropriate treatment.

Outcomes of Adolescent and Adult Patients with Lung Metastatic Osteosarcoma and Comparison of Synchronous and Metachronous Lung Metastatic Groups.

Osteosarcomas with lung metastases are rather heterogenous group. We aimed to evaluate the clinicopathological characteristics and outcomes of osteosarcoma patients with lung metastases and to compare the synchronous and metachronous lung metastatic groups. A total of 93 adolescent and adult patients with lung metastatic osteosarcoma, from March 1995 to July 2011, in a single center, were included. Sixty-five patients (69.9%) were male. The median age was 19 years (range, 14-74). Thirty-nine patients (41.9%) had synchronous lung metastases (Group A) and 54 patients (58.1%) had metachronous lung metastases (Group B). The 5-year and 10-year post-lung metastases overall survival (PLM-OS) was 17% and 15%, respectively. In multivariate analysis for PLM-OS, time to lung metastases (p = 0.010), number of metastatic pulmonary nodules (p = 0.020), presence of pulmonary metastasectomy (p = 0.007) and presence of chemotherapy for lung metastases (p< 0.001) were found to be independent prognostic factors. The median PLM-OS of Group A and Group B was 16 months and 9 months, respectively. In Group B, the median PLM-OS of the patients who developed lung metastases within 12 months was 6 months, whereas that of the patients who developed lung metastases later was 16 months. Time to lung metastases, number and laterality of metastatic pulmonary nodules, chemotherapy for lung metastatic disease and pulmonary metastasectomy were independent prognostic factors for patients with lung metastatic osteosarcoma. The best PLM-OS was in the subgroup of patients treated both surgery and chemotherapy. The prognosis of the patients who developed lung metastases within 12 months after diagnosis was worst.

Sequential therapy and prognostic factors in metastatic renal cell carcinoma: single centre experience.

PURPOSE: In advanced stage renal cell cancer (RCC), overall survival (OS) of patients has been prolonged due to targeted therapies. To date, there are several prognostic risk models that have been developed for metastatic RCC (mRCC). The purpose of this study was to evaluate the outcomes of the sequential therapy (IFN-α, tyrosine kinase inhibitors/TKIs, m-TOR inhibitor) and prognostic factors in patients with mRCC, especially those with bone metastasis. METHODS: We retrospectively examined the data of 82 patients with pathologically proven mRCC who were followed-up and treated at the Medical Oncology Clinic of the Dr A.Y Oncology Hospital between 2005 and 2013. RESULTS: Median OS was 23 months in all patients with mRCC and 20 months in patients treated with TKIs. According to MSKCC and HENG risk classifications, median OS differed between the groups (p=0.02, p<0.001, respectively). Median OS was lower in patients with isolated bone metastasis compared to those with lung metastasis (16 vs 24 months, p=0.25). Median OS improved with increasing number of sequential therapies (p=0.08). CONCLUSION: This study confirmed the correlation between MSKCC and HENG risk models and survival data. Additionally, it was shown that increase of the number of therapeutic lines in sequential therapy prolonged survival and that bone metastases were negative prognostic factors.
