Long-Term Survival after Stereotactic Radiotherapy Combined with Immunotherapy in a Patient with Recurrent Oral Cancer.

Introduction: Recurrent oral squamous cell carcinoma (SCC) poses significant challenges in treatment, requiring a multifaceted approach for effective management.

Case Presentation: We present the case of a 68-year-old patient with a history of keratonizing SCC of the mandibular gingiva, treated with surgical resection, adjuvant radiotherapy (RT) to a total dose of 60 Gy in 30 fractions and 6 cycles of concurrent chemotherapy. After 6 years of follow-up, the patient experienced a local late recurrence in clinical stage rT4N0M0 requiring palliative chemotherapy (6 cycles of PF regimen).

Nivolumab in patients with recurrent or metastatic squamous cell carcinoma of the head and neck: Results of Polish multicenter observational study.

Patients with head and neck squamous cell carcinoma (HNSCC) who have progressed following primary treatment (PT) have a poor prognosis. In this group, nivolumab has been demonstrated to significantly improve outcomes. This study presents the efficacy of nivolumab in Polish patients with recurrent and/or metastatic (R/M) HNSCC using real-world data.

Clinical practice in European centres treating paediatric posterior fossa tumours with pencil beam scanning proton therapy.

Background And Purpose: As no guidelines for pencil beam scanning (PBS) proton therapy (PT) of paediatric posterior fossa (PF) tumours exist to date, this study investigated planning techniques across European PT centres, with special considerations for brainstem and spinal cord sparing.

Materials And Methods: A survey and a treatment planning comparison were initiated across nineteen European PBS-PT centres treating paediatric patients. The survey assessed all aspects of the treatment chain, including but not limited to delineations, dose constraints and treatment planning.

Determinants of the level of circulating-tumor HPV16 DNA in patients with HPV-associated oropharyngeal cancer at the time of diagnosis.

Circulating tumor HPV DNA (ctHPV16) assessed in liquid biopsy may be used as a marker of cancer in patients with HPV-associated oropharyngeal cancer (HPV + OPC). Factors influencing the initial ctHPV16 quantity are not well recognized. In this study we aimed to establish what factors are related to the level of ctHPV16 at the time of diagnosis.

Intracranial Germinoma-Association between Delayed Diagnosis, Altered Clinical Manifestations, and Prognosis.

Background: Intracranial germinoma is a rare malignant neoplasm of the central nervous system (CNS) that occurs in children and young adults. The aim of our study was to assess the initial manifestation of the disease, and to find differences in outcomes dependent on time of diagnosis.

Methods: The study group consisted of 35 consecutive patients (adults and children) who were treated for intracranial germinoma with radiotherapy at a tertiary centre, and their data were retrospectively collected.

Early Diagnosis of Low-Risk Papillary Thyroid Cancer Results Rather in Overtreatment Than a Better Survival.

We are witnessing a rapid worldwide increase in the incidence of papillary thyroid carcinoma (PTC) in the last thirty years. Extensive implementation of cancer screening and wide availability of neck ultrasound or other imaging studies is the main reason responsible for this phenomenon. It resulted in a detection of a growing number of clinically asymptomatic PTCs, mainly low-risk tumors, without any beneficial impact on survival.
