ABSTRACT
Tuberous sclerosis complex (Bourneville-Pringle syndrome) is a rare genetic condition included in the group of diseases called phakomatoses. Most of the patients are diagnosed with abnormalities within the central nervous system and tend to develop tumors more frequently, especially gliomas. We present a case of 50-year-old patient suffering from tuberous sclerosis complex, who had been diagnosed with pleomorphic xanthoastrocytoma (PXA). The patient underwent surgery and adjuvant radiotherapy and has remained free from local recurrence for 5 years.

OBJECTIVES: Radiotherapy in patients with sinonasal mucosal melanoma (SNMM) was given as alternative treatment to surgery in cases with advanced, inoperable tumors or those not eligible for surgery. We presented the outcomes for patients with SNMM treated with radiotherapy alone. MATERIAL AND METHODS: The retrospective review of 6 consecutive SNMM (nasal cavity - 4 pts. and paranasal sinus - 2 pts.) patients (3 males and 3 females at mean age 64 years) treated between 2008 and 2016 was presented. The stage of disease was: T3 (1 pt.), T4a (3 pts.), T4b (2 pts.); with N0 and M0 in all patients. All patients underwent definitive primary photon radiotherapy (IMRT) alone; dose 66-72 Gy was delivered in 22-24 fractions given in 5 fractions (3 Gy) a week. RESULTS: The complete remission was observed in all our patients but only one patient survived 5 years without disease. Five patients died due to multiple distant metastases; two of those patients developed associated local recurrence 7-8 months after radiotherapy. CONCLUSION: SNMM has a poor prognosis due to its high metastatic potential. Based on our numerically small report and data from literature we concluded that primary radiotherapy alone assured complete remission and even 5-year disease-free survival in only a few individual patients.
ABSTRACT
This article presents methods and results of surgery and radiotherapy of brain metastases from non-small cell lung cancer (BMF-NSCLC). Patients with single BMF-NSCLC, with Karnofsky score ≥ 70 and controlled extracranial disease are the best candidates for surgery. Stereotactic radiosurgery (SRS) is recommended in patients with 1-3 BMF-NSCLC below 3-3.5 cm, with minor neurological symptoms, located in parts of the brain not accessible to surgery, with controlled extracranial disease. Whole brain radiotherapy (WBRT) following SRS reduces the risk of local relapse; in selected patients median survival reaches more than 10 months. Whole brain radiotherapy alone is a treatment in patients with multiple metastases, poor performance status, uncontrolled extracranial disease, disqualified from surgery or SRS with median survival 3 to 6 months. There is no doubt that there are patients with BMF-NSCLC who should receive only the best supportive care. There is a debate in the literature on how to select these patients.
ABSTRACT
The purpose of the present study was to carry out multivariate analysis of the effect of the expression of estrogen and progesterone receptors, p53, proliferative antigen (Ki67) and c-erbB-2 on 5-year survival in patients with invasive breast carcinoma concomitant with ductal carcinoma in situ. Material for study consisted of tissue specimens obtained from 48 patients undergoing modified Patey's mastectomy between 1991 and 1998. Univariate analysis revealed that the variables significantly affecting survival were tumour size on gross examination and the level of estrogen and progesterone receptors in the cells of invasive ductal carcinoma of the breast (for the level of significance p = 0.05). The Cox regression model revealed that the only independent variable having a significant effect on survival was the level of estrogen receptors in invasive cancer cells.
