Abstract
BACKGROUND Stereotactic radiotherapy (SRT) and Proton therapy (PT) are both options in the management of liver lesions. Limited clinical-dosimetric comparison are available. Moreover, dose-constraint routinely used in liver PT and SRT considers only the liver spared, while optimization strategies to limit the liver damaged are poorly reported. METHODS Primary endpoint was to assess and compare liver sparing of four contemporary RT techniques. Secondary endpoints were freedom from local recurrence (FFLR), overall survival (OS), acute and late toxicity. We hypothesize that Focal Liver Reaction (FLR) is determined by a similar biologic dose. FLR was delineated on follow-up MRI. Mean C.I. was computed for all the schedules used. A so-called Fall-off Volume (FOV) was defined as the area of healthy liver (liver-PTV) receiving more than the isotoxic dose. Fall-off Volume Ratio (FOVR) was defined as ratio between FOV and PTV. RESULTS 213 lesions were identified. Mean best fitting isodose (isotoxic doses) for FLR were 18Gy, 21.5 Gy and 28.5 Gy for 3, 5 and 15 fractions. Among photons, an advantage in terms of healthy liver sparing was found for Vmat FFF with 5mm jaws (p = 0.013) and Cyberknife (p = 0.03). FOV and FOVR resulted lower for PT (p < 0.001). Three years FFLR resulted 83%. Classic Radiation induced liver disease (RILD, any grade) affected 2 patients. CONCLUSIONS Cyberknife and V-MAT FFF with 5mm jaws spare more liver than V-MAT FF with 10 mm jaws. PT spare more liver compared to photons. FOV and FOVR allows a quantitative analysis of healthy tissue sparing performance showing also the quality of plan in terms of dose fall-off.

Abstract
BACKGROUND Platinum-based chemoradiotherapy and brachytherapy are the standard treatment for locally advanced cervical cancer. Reported long-term outcomes for treated with both IMRT and 3D-Image-guided-adaptive brachytherapy are lacking. METHODS This retrospective study included 165 patients with FIGO Stage IB-IVB cervical cancer, treated with chemoradiotherapy in combination with brachytherapy. External beam radiotherapy was delivered as IMRT/VMAT/TOMO helical or 3DCRT. The intracavitary brachytherapy treatment (ICBT) was performed using two different planning system (with or without optimization). RESULTS Among the patient subgroups, comprising those who received IMRT/VMAT/Tomo helical and 3DCRT, as well as those who underwent ICBT planning optimization and those who did not, homogeneity was observed in terms of age, performance status, T stage, N status, TNM stage, and histology. With a median follow-up time of 60.5 months, the 5-year overall survival (OS) in the 3DCRT and IMRT groups was 74.9% and 92.8%, respectively (p = 0.033). The 5-year OS in the ICBT planning optimization group was 93.7%, compared to 75% in the non-optimization group (p = 0.014). Regarding late radiation toxicities, patients in the IMRT group had a lower incidence of chronic rectal toxicity compared to those in the 3DCRT group (6.5% vs. 34.1%, p = 0.001). The group with ICBT planning optimization had a lower incidence of late urinary toxicities (10.4%) compared to the non-optimized ICBT planning group (18.2%, p = 0.012). Similarly, the ICBT planning optimization group had a lower incidence of late rectal toxicity (6.5% with 80% grade 1 and 20% grade 2) compared to the non-optimized ICBT planning group (34.1%, p = 0.001). CONCLUSION In this series, the group of patients receiving optimized ICBT had an advantage in terms of OS and CSS suggesting that the use of new Treatment Planning Systems associated with 3D imaging, improves the long-term survival. Additionally, a significant reduction in late rectal and urinary toxicity has been observed.

Abstract
Objective The therapeutic landscape for localized prostate cancer (PC) is evolving. Stereotactic radiotherapy (SRT) has been reported to be at least not inferior to standard radiotherapy, but the effect of androgen deprivation therapy (ADT) in this setting is still unknown and its use is left to clinical judgment. There is therefore the need to clarify the role of ADT in association with SRT, which is the aim of the present study. Methods We present a study protocol for a randomized, multi-institutional, Phase III clinical trial, designed to study SRT in unfavorable intermediate and a subclass of high-risk localized PC. Patients (pts) will be randomized 1:1 to SRT + ADT or SRT alone. SRT will consists in 36.25 Gy in 5 fractions, ADT will be a single administration of Triptorelin 22.5 mg concurrent to SRT. Primary end point will be biochemical disease-free survival. Secondary end points will be disease-free survival, freedom from local recurrence, freedom from regional recurrence, freedom from distant metastasis and overall survival (OS); quality of life QoL and patient reported outcomes will be an exploratory end point and will be scored with EPIC-26, EORTC PR 25, IPSS, IIEF questionnaires in SRT + ADT and SRT alone arms. Moreover, clinician reported acute and late toxicity, assessed with CTCAE v. 5.0 scales will be safety end points. Results Sample size is estimated of 310 pts. For acute toxicity and quality of life results are awaited after 6 months since last patient in, whereas, for efficacy end points and late toxicity mature results will be available 3-5 years after last patient in. Conclusion Evidence is insufficient to guide decision making concerning ADT administration in the new scenario of prostate ultra-hypofractionation. Hence, the need to investigate the ADT role in SRT specific setting. Advances in knowledge The stereotactic prostate radiotherapy with or without ADT trial (SPA Trial) has been designed to establish a new standard of care for SRT in localized unfavorable intermediate and a subclass of localized high risk PC.

Abstract
Introduction Radiochemotherapy (RCHT) for the treatment of anal squamous cell carcinoma (ASCC) has evolved dramatically, also thanks to intensity-modulated RT (IMRT) and 3D image guidance (3D IGRT). Despite most patients presenting fair outcomes, unmet needs still exist. Predictors of poor tumor response are lacking; acute toxicity remains challenging; and local relapse remains the main pattern of failure. Patients and methods Between 2010 and 2020, ASCC stages I–III treated with 3D conformal radiotherapy or IMRT and CDDP-5FU or Mytomicine-5FU CHT were identified. Image guidance accepted included 2D IGRT or 3D IGRT. The study endpoints included freedom from locoregional recurrence (FFLR), colostomy free survival (CFS), freedom from distant metastasis (FFDM), overall survival (OS), and acute and late toxicity as measured by common terminology criteria for adverse events (CTCAE) version 5.0. An exploratory analysis was performed to identify possible radiomic predictors of tumor response. Feature extraction and data analysis were performed in Python™, while other statistics were performed using SPSS® v.26.0 software (IBM®). Results A total of 131 patients were identified. After a median FU of 52 months, 83 patients (63.4%) were alive. A total of 35 patients (26.7%) experienced locoregional failure, while 31 patients (23.7%) relapsed with distant metastasis. Five year FFLR, CFS, DMFS and PS resulted 72.3%, 80.1%, 74.5% and 64.6%. In multivariate analysis, 2D IGRT was associated with poorer FFLR, OS, and CFS (HR 4.5, 4.1, and 5.6, respectively); 3DcRT was associated with poorer OS and CFS (HR 3.1 and 6.6, respectively). IMRT reduced severe acute gastro-intestinal (GI) and severe skin acute toxicity in comparison with 3DcRT. In the exploratory analysis, the risk of relapse depended on a combination of three parameters: Total Energy, Gray Level Size Zone Matrix’s Large Area High Gray Level Emphasis (GLSZM’s LAHGLE), and GTV volume. Conclusions Advances in radiotherapy have independently improved the prognosis of ASCC patients over years while decreasing acute GI and skin toxicity. IMRT and daily 3D image guidance may be considered standard of care in the management of ASCC. A combination of three pre-treatment MRI parameters such as low signal intensity (SI), high GLSZM’s LAHGLE, and GTV volume could be integrated in risk stratification to identify candidates for RT dose-escalation to be enrolled in clinical trials.

Abstract
OBJECTIVE This review aimed at examining efficacy of interventional radiotherapy (brachytherapy-IRT) alone or combined with external beam radiotherapy (EBRT) in stage I esophageal cancer as exclusive treatment. MATERIALS AND METHODS A systematic research using PubMed, Scopus, and Cochrane library was performed. ClinicalTrials.gov was searched for ongoing or recently completed trials, and PROSPERO was searched for ongoing or recently completed systematic reviews. We analyzed only clinical study as full-text publication, reporting on patients with stage I esophageal cancer treated with IRT alone or in combination with other treatments (e.g., EBRT). Conference paper, survey, letter, editorial, book chapter, and review were excluded. Patients who underwent previous surgery were excluded. Time restriction (1990-2018) was applied for years of the publication. RESULTS Twelve studies have been selected. The number of evaluated patients was 514; the median age was 69 years. In the IRT group, the median: local control (LC) was 77% (range 63%-100%), disease-free survival (DFS) was 68.4% (range 49%-86.3%), the overall survival (OS) was 60% (range 31%-84%), the cancer specific survival (CSS) was 80% (range 55-100%), and grade 3-4 toxicity range was 0%-26%. CONCLUSIONS IRT alone or combined to EBRT is an effective and safe treatment option for patients with stage I esophageal cancer. Definitive radiation therapy could be an alternative to surgery in patients with superficial cancer.

Abstract
Anticancer treatment efficacy is limited by the development of refractory tumor cells characterized by increased expression and activity of mechanisms promoting survival, proliferation, and metastatic spread. The present review summarizes the current literature regarding the use of the anthelmintic mebendazole (MBZ) as a repurposed drug in oncology with a focus on cells resistant to approved therapies, including so called “cancer stem cells”. Mebendazole meets many of the characteristics desirable for a repurposed drug: good and proven toxicity profile, pharmacokinetics allowing to reach therapeutic concentrations at disease site, ease of administration and low price. Several in vitro studies suggest that MBZ inhibits a wide range of factors involved in tumor progression such as tubulin polymerization, angiogenesis, pro-survival pathways, matrix metalloproteinases, and multi-drug resistance protein transporters. Mebendazole not only exhibits direct cytotoxic activity, but also synergizes with ionizing radiations and different chemotherapeutic agents and stimulates antitumoral immune response. In vivo, MBZ treatment as a single agent or in combination with chemotherapy led to the reduction or complete arrest of tumor growth, marked decrease of metastatic spread, and improvement of survival. Further investigations are warranted to confirm the clinical anti-neoplastic activity of MBZ and its safety in combination with other drugs in a clinical setting.
