RESUMO
BACKGROUND: The combination of pentoxifylline (Trental) and vitamin E has been reported to reverse significant consequences of radiation after mastectomy with immediate reconstruction, such as severe capsular contracture or loss of implants. We questioned whether prophylactic use could prevent these consequences. METHODS: Thirty women with implants or tissue expanders after mastectomy that underwent adjuvant radiation were treated with Trental and vitamin E for 180 days. All subjects then entered a 12-month observational phase. RESULTS: Of the 26 evaluable subjects, 3 subjects required implant revisions. One due to malposition of the nonradiated breast and 2 were due to contracture (7.7%). There were no implant losses. CONCLUSIONS: The combination of Trental and vitamin E can prevent severe contracture and implant losses allowing for immediate reconstruction with implant or tissue expander even if radiation is planned after mastectomy.

BACKGROUND: Both MRI and breast-specific gamma imaging are tools for surgical planning in newly diagnosed breast cancer. Breast-specific gamma imaging (BSGI) is used less frequently although it is of similar utility and lower cost. We compared the diagnostic and cost efficacy of BSGI with MRI. METHODS: Retrospective review of 1,480 BSGIs was performed in a community breast health center, 539 had a new diagnosis of cancer, 75 patients having both MRI and BSGI performed within 2 months of each other. Institutional charges for BSGI ($850) and MRI ($3,381) were noted. RESULTS: BSGI had a sensitivity of 92%, specificity of 73%, positive predictive value of 78%, and negative predictive value of 90%. This compared favorably with MRI that had sensitivity of 89%, specificity 54%, positive predictive value 67%, and negative predictive value 83%. The accuracy of BSGI was higher at 82% vs MRI at 72%. Total cost of MRI imaging was $253,575 vs BSGI at $63,750. CONCLUSIONS: BSGI is a cost-effective and accurate imaging study for further evaluation of dense breast tissue and new diagnosis of cancer.
