Extramedullary solitary plasmacytoma (EMP) is a rare type of malignancy. This paper presents a retrospective review of the experience with EMP at the Krakow Oncology Center. Records of 17 patients with head and neck EMP, treated with definitive radiotherapy between 1976 and 2009, were analyzed. The total tumour dose ranged from 45 to 70 Gy (median 56 Gy). In four patients with partial response after radiotherapy, adjuvant melphalan-based chemotherapy was applied. The median follow-up period was 8.6 years. The treatment was well tolerated. The estimated 10-year overall survival, disease-free survival, and multiple myeloma-free survival were 68.4%, 49.3%, and 55%, respectively. The 10-year local control rate was 90.9%. No in-field local recurrence was observed. During the follow-up, progression into multiple myeloma was observed in five patients, with a mean time to conversion of 24 months. The only factor adversely affecting overall survival on univariate analysis was the age >56 years, whereas a complete tumour regression after radiotherapy was associated with a significant improvement in both disease-free survival and multiple myeloma-free survival. Despite the high effectiveness of local radiotherapy, there is still a significant treatment failure risk due to the EMP conversion into generalized disease. An attempt to identify prognostic factors may facilitate selection of patients with a high risk of progression to multiple myeloma. Copyright © 2015 John Wiley & Sons, Ltd.

Aim of the studyTo evaluate the toxicity, clinical effectiveness and survival rate of transurethral resection, neoadjuvant chemotherapy and accelerated hyperfractionated radiotherapy (concomitant boost), with or without concurrent cisplatin in patients with muscle invasive bladder cancer.Material and methodsBetween March 2004 and December 2009, 35 patients with histologically proven invasive carcinoma of the bladder (T2-4a, N0-1, M0), who were fit for combined radiochemotherapy and refused radical surgery or were medically or surgically inoperable, were selected for the bladder-sparing protocol.ResultsIn this study, twenty-five patients (25/35; 72%) received two cycles of neoadjuvant chemotherapy, and ten of them (10/35; 28%) only one, because of treatment-related toxicity. In twenty-one patients (21/35; 60%) chemotherapy consisting of gemcitabine with cisplatin and in fourteen patients (14/35; 40%) gemcitabine with carboplatin were applied. Only 13 patients (13/35; 37%) received combined irradiation with cisplatin. All patients completed their planned course of radiation therapy. Complete response (CR) occurred in 26/35 (74%) patients, partial response (PR) in 2/35(6%), and stable disease (SD) in 7/35 (20%). The overall actuarial survival rates at 3 and 5 years were 75% and 66%, respectively. Disease-specific actuarial survival rates at 3 and 5 years were 81% and 71%, respectively.ConclusionsConservative treatment of patients with muscle-invasive bladder cancer by transurethral resection, neoadjuvant chemotherapy, and accelerated hyperfractionated radiotherapy with concomitant boost, with or without concurrent cisplatin, provides a high probability of local and distal response with acceptable toxicity in properly selected patients.

Radiotherapy in breast cancer patients is an important component of multidisciplinary treatment. It reduces the risk of local recurrence and mortality from breast cancer. However, it can lead to secondary effects due to the presence of the heart within the irradiation field. Adjuvant radiation therapy for breast cancer increases the risk of coronary artery disease, myocardial infarction and cardiovascular death. It is important to determine the optimal treatment to minimize cardiotoxicity. Modern radiotherapy techniques may reduce radiation-induced cardiac toxicity, but it is necessary to determine the most sensitive structures within the heart, tolerance doses, and methods for early detection and monitoring of adverse effects.
