Pelvic bone marrow dose-volume predictors of late lymphopenia following pelvic lymph node radiation therapy for prostate cancer
The interest concerning radiation-induced hematological toxicity (HT) increased in the last years [1 –7]. The occurrence of severe decrease of blood counts is a well assessed side-effect experienced by many patients undergoing radiochemotherapy [1,6,8–10] and several investigations showed clear association between the incidence and severity of HT and the extent of bone marrow (BM) and of body i rradiated, as well as the delivered dose and fractionation [1,11–14]. On the other hand, the interest in quantifying these effects induced by radiation only (i.e.: without chemotherapy) is equally high, aiming to estimate the ...

Stereotactic radiotherapy for head and neck paragangliomas: How long should we wait for treatment response?
Paragangliomas are uncommon neuroendocrine tumors originating from extra-adrenal paraganglionic structures of the peripheral nervous system. They may derive from either the sympathetic or the parasympathetic branches of the peripheral nerves [1]. Tumors originating from the sympathetic system can be found in diverse locations, while those arising from the parasympathetic system are predominantly located in the head and neck (H&N) region [2]. Paragangliomas are usually characterized by a gradual growth pattern and they rarely metastasize [3]. (Source: Radiotherapy and Oncology)

Proton beam radiotherapy head and neck cancer study design and endpoints
We thank Friborg et al for sharing Denmark ’s important contributions to the evidence base for proton beam therapy in head and neck cancer patients [1]. In the Danish model, head and neck squamous cell cancer (SCC) in all sub-sites excluding early T1-2N0M0 larynx were included. Patients are double planned with comparisons made between prot on-photon dosimetry and a 5% superiority in the normal tissue complication probability (NTCP) model estimated risk for xerostomia and dysphagia is used to guide randomisation into DAHANCA35.

Professional development through mentoring: Final evaluation of the pilot mentoring programme of the European society of radiotherapy and oncology
A large body of literature exists on the importance of mentoring in healthcare. It is increasingly recognized as a bidirectional process where both mentors and mentees benefit. Benefits for the mentees include increased self-efficacy, job satisfaction and productivity at work, while mentors can benefit through personal fulfilment, and the development of leadership and coaching skills [1]. These advantages are also pertinent for radiation oncology (RO). While mentorship appears to be exceptionally valuable also in RO, it remains understudied [2 –4]. (Source: Radiotherapy and Oncology)

Clinical practicality and patient performance for surface-guided automated VMAT gating for DIBH breast cancer radiotherapy
Radiotherapy (RT) is applied after breast-conserving surgery to enhance local control and overall survival in breast cancer patients [1]. As a consequence and particularly among patients with left-sided breast cancer, radiation dose is incidental partially delivered to the heart and lungs, which is known to increase the risk of cardiovascular and lung disease [2,3]. Advanced radiation techniques like volumetric modulated arc therapy (VMAT) have been developed to deliver more precise and conformal doses to better spare the heart and lungs [4 –6].

ESTRO-SIOPE guideline: Clinical management of radiotherapy in atypical teratoid/rhabdoid tumors (AT/RTs)
Atypical teratoid/rhabdoid tumors (AT/RT) are tumors of the central nervous system (CNS) most commonly diagnosed in very young children [1 –5], with most (70–80 %) tumors found in children under three years of age [6,7]. The German Childhood Cancer Registry reported that the median age at diagnoses was 18 months [8]. These rare embryonal tumors are locally aggressive and one of the most malignant CNS tumors. Also, they spread t hroughout the CNS by cerebrospinal fluid (CSF). Up to one-third of the patients have disseminated disease in the brain or spinal canal or both at diagnosis [9,10].

Proposals for the delineation of neck clinical target volume for definitive Radiation therapy in patients with oral/ oropharyngeal squamous cell cancer based on lymph node distribution
Oral squamous cell carcinoma (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC) are the most common types of head and neck cancer [1], constituted 2.5  % of global malignancies in 2018 [2]. Approximately 60 % of OSCC/OPSCC cases are diagnosed as locally advanced, with 50 % considered unresectable [3]. In addition, over 50 % of these cases exhibit cervical lymph node metastasis (LNM) upon initial diagnosis, with the risk varying based on th e tumor location, size, and pathological characteristics [4,5].

A population-based analysis of the impact of 1 vs. 2 doses of mitomycin on patterns of failure of anal cancer patients treated with concurrent chemoradiotherapy
Anal cancer (AC) is an uncommon malignancy accounting for about 2.6% of all gastrointestinal (GI) tract cancers, with squamous cell carcinoma (SCC) being the most common histological type [1]. Although relatively rare, it is well documented that the incidence of AC is rising, notably in higher income countries [2,3]. Definitive chemoradiotherapy (CRT) with 5-fluorouracil and mitomycin-C (5FU/MMC) is the treatment of choice for non-metastatic anal canal SCC (ASCC). CRT is an alternative strategy to abdominoperineal resection that preserves the anatomical sphincter in up to 80 % of cases, and results in significantly improve...

Predicting overall survival and prophylactic cranial irradiation benefit in small-cell lung cancer with CT-based deep learning: A retrospective multicenter study
Lung cancer remains the leading cause of cancer-related deaths worldwide. In the United States alone in 2022, it accounted for approximately 130,180 fatalities, constituting 21% of all cancer-related mortality [1]. Small-cell lung cancer (SCLC), a subtype of lung cancer, is a highly aggressive neuroendocrine tumor with poor differentiation. It tends to metastasize early and has an unfavorable prognosis, accounting for roughly 15% of all lung cancer cases [2,3]. Currently, SCLC is categorized into limited and extensive stages according to the widely accepted staging criteria of the Veteran Affairs Lung Group, with extensive...

A systematic review of circulating predictive and prognostic biomarkers to aid the personalised use of radiotherapy in the radical treatment of patients with oesophageal cancer
Oesophageal cancer is the sixth leading cause of cancer-related death worldwide, accounting for an annual global burden of around 544,000 deaths [1]. There are two major subtypes, oesophageal adenocarcinoma (OAC) and oesophageal squamous cell carcinoma (OSCC). Treatment approaches increasingly diverge between these subtypes, though radiotherapy (RT) is an important component of available therapeutic strategies for both. (Source: Radiotherapy and Oncology)

Dosimetric impact of bone marrow sparing for robustly optimized IMPT for locally advanced cervical cancer
Standard treatment of locally advanced cervical cancer (LACC) combines external beam radiotherapy, cisplatin-based concurrent chemotherapy, and image-guided brachytherapy [1]. Although this treatment combination provides a good clinical outcome in terms of local and pelvic tumor control [2,3], it is associated with a high incidence of morbidities, including gastrointestinal (GI) and genitourinary (GU) toxicities as well as hematologic toxicity (HT) [4,5]. HT, and more specifically radiation-induced lymphopenia, has been associated with a poorer prognosis on overall survival [6,7]. (Source: Radiotherapy and Oncology)

Longitudinal changes in the carotid arteries of head and neck cancer patients following radiation therapy: Results from a prospective serial imaging biomarker characterization study
Radiation therapy (RT) is an integral part of the treatment of head and neck cancer [1]. Most patients require treatment to the cervical lymph nodes adjacent to the carotid arteries, which most often cannot be excluded from the RT volume. This increases the risk for accelerated atherosclerosis, carotid artery stenosis and subsequent transient ischemic attack (TIA) and cerebrovascular accident (CVA) [2,3]. The long latent interval of several years from RT to the development of carotid artery stenosis makes it difficult to identify patients who will develop adverse outcomes [4,5].

Optimal hypofractionated radiation therapy schemes for early-stage hepatocellular carcinoma
Hepatobiliary cancer is the second leading cause of cancer death worldwide [1]. The majority ( ∼90 %) of hepatobiliary cancer is hepatocellular carcinoma (HCC) which may result in liver cirrhosis. The major risk factors are chronic infection of hepatitis B and C viruses in Asia, while chronic heavy alcohol use, obesity, and diabetes in the USA and Europe. Despite of improved HCC screening , prevention, and treatment of the risk factors, the incurrence and mortality rates continue to rise. The treatment options for patients with early-stage hepatobiliary cancer are surgery, transplantation, and/or ablation. (Source: Rad...
