ABSTRACT
Introduction: A patient with synchronous bilateral breastcancer was treated with Rapid arc (Volumetric Modulated Arctherapy - VMAT) radiotherapy following breast conservationsurgery. She is alive and without radiotherapy complicationsin the 10 year follow up period.Case report: A 51 year old lady presented with synchronousbilateral breast cancer. She underwent wide excision of bothbreast lumps with bilateral axillary lymph node sampling(Invasive Ductal Carcinoma, pT1N1 in left breast and pT2N0in right breast). She was treated with adjuvant chemotherapyand post-operative radiotherapy to both breasts with rapidarc (VMAT) technique in August 2009. The radiotherapyplanning was compared among Three Dimensional ConformalRadiotherapy, Intensity Modulated Radiotherapy and Rapidarc techniques. Details of dose homogeneity and sparing ofOrgans at risk are discussed. She tolerated the treatment wellwithout major toxicity. She has been on regular follow up tillher last visit in June 2019. She was also treated for surgeryfollowed by radiotherapy for Carcinoma of cervix 12 yearsago.Conclusion: This case is presented for the novel radiotherapytechnique in treating bilateral breast cancer resulting in goodquality of life and long term survival.
