QUAD SHOT - an effective hypofractionated palliative radiotherapy in patients with non-melanoma skin cancer. A single-institution experience.

Introduction: The primary approach for managing skin cancer involves surgery, although radical radiotherapy (RT) may be considered as an alternative option in cases where patients decline the treatment themselves or are not eligible for surgical intervention. Herein we assess single-institution material in terms of the use of hypofractionated QUAD SHOT RT in patients disqualified from surgery.

Material And Methods: Between December 2019 and December 2022, nine patients with locally advanced non-melanoma skin cancer were disqualified from surgery and as a result were treated at the Radom Oncology Centre, Poland.

Screening for EGFR amplifications with a novel method and their significance for the outcome of glioblastoma patients.

Glioblastoma is a highly aggressive tumour of the central nervous system, characterised by poor prognosis irrespective of the applied treatment. The aim of our study was to analyse whether the molecular markers of glioblastoma (i.e.

Response to postoperative radiotherapy as a prognostic factor for patients with low-grade gliomas.

Due to the favorable natural history in patients with low-grade gliomas (LGGs), there is no consensus on the treatment strategy following maximal safe surgical resection. A number of studies have been conducted to identify prognostic factors in patients treated for LGG. The present study evaluated the treatment outcomes as well as prognostic factors and their impact on overall survival (OS) and disease-free survival (DFS).

Solitary brain metastasis of an occult and stable small-cell lung cancer in a schizophrenic patient: a 3-year control.

Small-cell lung cancer is a highly aggressive carcinoma, with poorer prognosis in patients with brain metastases. We present the case of a 49-year-old woman diagnosed with a cerebellar tumour which, following surgery, was revealed to be a metastatic small-cell lung carcinoma. Subsequent CT and PET scanning showed a small, isolated 8 mm nodule in the upper lobe of the right lung.

High incidence of MGMT promoter methylation in primary glioblastomas without correlation with TP53 gene mutations.

O(6)-methylguanine DNA methyltransferase (MGMT) reduces cytotoxicity of therapeutic or environmental alkylating agents. MGMT promoter methylation has been associated with TP53 G: C to A:T transition mutations in various types of cancers, and with poor prognosis in patients who did not receive chemotherapy. Mutations of TP53 are more frequent in secondary than in primary glioblastoma, thus the expected MGMT promoter methylation was low in primary glioblastoma.
