RESUMO
BACKGROUND: Glomus tumors are difficult to manage surgically because they are vascular tumors that are topographically associated with important vascular and neuronal structures. Hence, there is a strong risk of incomplete resection and a high morbidity rate. In addition, they grow slowly. Recent treatments have increasingly involved a combination of surgical resection and radiosurgery. We present our experience in treating glomus tumors of the skull base with stereotactic radiosurgery as an upfront therapy. METHODS: We analyzed data from 13 consecutive patients with glomus tumors that were initially treated with stereotactic radiosurgery in our institute from February 2010 to April 2012. The tumor control rate, resolution of symptoms, and the complication rate were tabulated. RESULTS: All patients were female with a median age of 63 (mean 62.7+/-14.6 years). The median treatment dose was 25.8 Gy (27.6 Gy +/- 9.5 Gy) and the median tumor volume 10.4 mL (9.2 +/- 6.5). The median follow-up was 47.4 months (51.8+/-11.2 months, range 31-74). The tumor control rate was 92.3%; 46.7% of the patients had noticeable tumor shrinkage. This happened at a median interval of 17 months (18.7+/-6.8) after treatment. Most patients with tinnitus had resolution of their symptoms (87.5%). Four patients presented with new symptoms and four patients with worsening of pre-existing symptoms. The time course of symptomatic improvement followed that of tumor size reduction. However, there was no statistical correlation between the amount of tumor reduction and symptomatic relief. CONCLUSION: Stereotactic radiosurgery (SRS) is an effective upfront treatment option in the management of glomus tumors.
RESUMO
The standard treatment for patients with refractory or relapsed Hodgkin lymphoma (HL) is high-dose chemotherapy and/or radiation with autologous haematopoietic cell rescue (AHCR). In this study, we assessed quality of life and evaluated the risk of late morbidity and mortality for HL patients who underwent AHCR. One hundred and fifty-four patients who underwent AHCR at Stanford University from 1988 to 2002 and survived ≥2 years were evaluated. Median follow-up was 10·2 years. There were 54 deaths, 34 from HL, 20 from other causes. The 10-year cumulative incidence of death from HL or other causes was 21·7% and 12·7%, respectively. Thirteen deaths were from second malignancies. The risk ratio of second malignancies was 8·0 [95% confidence interval (CI), 4·7-12·6] compared with the general population, and 3·0 (95% CI, 1·8-4·8) compared with HL patients not undergoing AHCR. The risk ratio of second malignancies was 1·5 (95% CI, 0·9-2·4) compared with HL patients receiving non-AHCR therapy. Overall quality of life did not differ from the general population, but AHCR survivors did note reduced functioning and some worse symptoms. AHCR survivors may be at increased risk of death from HL and other causes compared with the general population, but not compared with the HL population as a whole.
