Mnogie atypowe nawrotowe oponiaki po 13 latach od radioterapii z powodu jednostronnego siatkówczaka: opis przypadku i przegląd piśmiennictwa

Radiotherapy is an important treatment modality for intracranial malignancies. Improved survival rates were achieved via a combination of surgery, chemotherapy and radiotherapy. On the other hand, improved survival rates made long-term complications of radiotherapy more apparent. Secondary neoplasms due to cranial irradiation are encountered more commonly in neurosurgical practice. Radiation-induced meningiomas are recognized as a common late complication of radiotherapy. However, radiation-induced meningiomas after radiotherapy for retinoblastoma have been reported rarely. Herein we report a patient who harboured multiple meningiomas 13 years after radiotherapy for unilateral retinoblastoma, which were recurrent despite surgical removal and chemotherapy.Radioterapia jest ważną metodą leczenia złośliwych guzów śródczaszkowych. Dzięki łącznemu stosowaniu leczenia chirurgicznego, chemioterapii i radioterapii osiąga się zwiększony odsetek przeżyć, ale jednocześnie sprawia to, że częściej ujawniają się odległe powikłania radioterapii. Guzy wtórne do napromieniania w obrębie głowy są znanymi i częstymi powikłaniami radioterapii. Rzadko opisywano jednak oponiaki wywołane napromienianiem prowadzonym z powodu siatkówczaka. W niniejszym artykule opisano przypadek pacjenta, u którego po 13 latach od radioterapii z powodu jednostronnego siatkówczaka wystąpiły mnogie oponiaki, które miały charakter nawracający mimo leczenia chirurgicznego i chemioterapii

Factors Associated with Late Toxicity in Nasopharyngeal Carcinoma Patients Treated with Radio-Chemotherapy

Objective: To quantify late toxicity in patients treated with intensive chemotherapy (ChT) and radiotherapy (RT) for nasopharyngeal carcinoma (NPC) and to investigate factors associated with it. Material and Methods: We retrospectively reviewed the treatment outcome in terms of moderate-severe late toxicity (MSLT) in 44 NPC patients diagnosed between 2001 and 2007. All the patients were treated with conformal RT and cisplatin containing ChT. Twenty-eight (63.6%) patients among 44 received only multidrug neoadjuvant ChT, while the remaining 16 (36.4%) patients received additional concomitant cisplatin during RT. MSLT was evaluated according to RTOG/EORTC scoring system and defined as grade 3-5 late toxicity. The median follow-up of these 44 patients was 38 months (range, 12-84 months). Statistical analyses were performed with Kaplan-Meier method and a multiple Cox's regression model. Results: The hazard probability of developing MSLT at 5 years was 49%. In univariate analyses; gender, age, histopathology, T stage, N stage and ChT schema did not have significant impact on treatment outcome in terms of MSLT. Total radiation dose to the neck, which appeared to have a paradoxical effect on late toxicity in univariate analysis turned to be insignificant in multivariate analysis. Treatment response was found to be the only prognostic factor in multiple Cox's regression analysis, which had an impact on MSLT in NPC patients. Probability of MSLT among the 12 NPC patients with less than complete response to the treatment was higher than 32 patients with complete response to the treatment (85.7% and 35.2% at 5 years, respectively; p=0.0254). Conclusion: Late toxicity in NPC patients is treatment related. Poor tumour control can be a triggering factor for development of late toxicity. Long lasting residual disease following treatment is an interesting phenomenon in NPC patients, which appears to be related with MSLT and has to be further investigated in prospective studies

Effectiveness of Black Mulberry Molasses in Prevention of Radiotherapy-Induced Oral Mucositis: A Randomized Controlled Study in Head and Neck Cancer Patients

Objectives: Radiation-induced oral mucositis is one of the problems experienced by 70%-80% of patients receiving radiation therapy (RT). This randomized controlled trial assessed the effectiveness of black mulberry molasses in the prevention of oral mucositis in head and neck cancer patients receiving RT
