Uterine body cancers (UBC) are represented by endometrial carcinoma (EC) and uterine sarcoma (USa). The clinical management of both is hindered by the complex classification of patients into risk classes. This problem could be simplified through the development of predictive models aimed at treatment tailoring based on tumor and patient characteristics. In this context, radiomics represents a method of extracting quantitative data from images in order to non-invasively acquire tumor biological and genetic information and to predict response to treatments and prognosis. Furthermore, artificial intelligence (AI) methods are an emerging field of translational research, with the aim of managing the amount of data provided by the various -omics, including radiomics, through the process of machine learning, in order to promote precision medicine.
The aim of this protocol for systematic review is to provide an overview of radiomics and AI studies on UBCs.
A systematic review will be conducted using PubMed, Scopus, and the Cochrane Library to collect papers analyzing the impact of radiomics and AI on UBCs diagnosis, prognostic classification, and clinical outcomes. The PICO strategy will be used to formulate the research questions: What is the impact of radiomics and AI on UBCs on diagnosis, prognosis, and clinical results? How could radiomics or AI improve the differential diagnosis between sarcoma and fibroids? Does Radiomics or AI have a predictive role on UBCs response to treatments? Three authors will independently screen articles at title and abstract level based on the eligibility criteria. The risk of bias and quality of the cohort studies, case series, and case reports will be based on the QUADAS 2 quality assessment tools.

Short course palliative radiotherapy in advanced solid tumors: a pooled analysis (the SHARON project)
2022
Previous trials showed the tolerability and efficacy of a palliative radiotherapy (RT) regimen (SHARON) based on the 4 fractions delivered in 2 days in different oncological settings. In order to identify possible predictors of symptomatic response, the purpose of this study is to perform a pooled analysis of previous trials. We analyzed the impact on symptomatic response of the following parameters: tumor site, histological type, performance status (ECOG), dominant symptom, and RT dose using the Chi-square test and Fisher’s exact test. One-hundred-eighty patients were analyzed. Median RT dose was 20 Gy (range: 14–20 Gy). The overall response rate was 88.8% (95% CI 83.3–92.7%) while pre- and post-treatment mean VAS was 5.3 (± 7.7) and 2.2 (± 2.2), respectively (
p
< 0.001). The overall response rate of pain, dyspnea, bleeding, dysphagia, and other symptoms was 86.2%, 90.9%, 100%, 87.5%, and 100%, respectively. Comparing the symptomatic effect based on the analyzed parameters no significant differences were recorded. However, patients with locally advanced disease showed a higher rate of symptomatic responses than metastatic ones (97.3% vs 83.0%;
p
= 0.021). Finally, the complete pain response rate was more than double in patients with mild to moderate (VAS: 4–7) compared to those with severe (VAS > 7) pain (36.0% vs 14.3%;
p
= 0.028). This pooled analysis showed high efficacy of the SHARON regimen in the relief of several cancer-related symptoms. The markedly and significantly higher complete pain response rate, in patients with mild-moderate pain, suggests early referral to palliative RT for patients with cancer-related pain.

Background
We provided a comprehensive analysis of rate, pattern, and severity of early and late postoperative complications in a very large, single-institution series of locally advanced cervical cancer (LACC) patients administered CT/RT plus radical surgery (RS).
Methods
A total of 362 consecutive LACC (FIGO stage IB2-IVA) patients were submitted to RS after CT/RT at the Gynecologic Oncology Unit of the Catholic University (Rome/Campobasso). At 4 weeks after CT/RT, patients were evaluated for objective response and triaged to radical hysterectomy and pelvic ± aortic lymphadenectomy. Surgical morbidity was classified according to the Chassagne’s grading system.
Results
Most cases underwent type III–IV radical hysterectomy (
N
= 313, 86.5 %); pelvic lymphadenectomy was performed in all patients, while 116 patients (32.1 %) were also submitted to aortic lymphadenectomy. A total of 93 patients (25.7 %) experienced any grade postoperative complications, and 60 (16.6 %) had ≥grade 2 complications; grade 3–4 complications occurred in 21 patients (5.8 %). Of all early postoperative complications (
N
= 100), 31 (31.0 %) were urinary, 9 (9.0 %) were gastrointestinal, and 45 (45.0 %) were vascular. Of all late complications (
N
= 31), 20 (64.5 %) were urinary, 7 (22.6 %) gastrointestinal, and 2 (6.4 %) were vascular. Multivariate analysis showed that not complete clinical response to treatment retained an independent, unfavorable association with risk of development of postoperative morbidity, while advanced stage, and aortic lymphadenectomy showed only a borderline value.
Conclusions
Failure to achieve clinical complete response to treatment and, to a lesser extent, more advanced stage, and aortic lymphadenectomy, were associated with a higher risk of developing any grade as well as ≥grade 2 complications.

Purpose: This prospective observational study aims to investigate which proportion of patients with bone metastases referred for External Beam Radiation Therapy (EBRT) would be able to undergo Magnetic Resonance‐guided High Intensity Focused Ultrasound (MR‐HIFU) as alternative to EBRT, and to examine reasons for ineligibility. Materials and Methods: Adult patients with nonspinal bone metastases referred to four radiotherapy departments were included. Local, multidisciplinary teams assessed which patients would be eligible for MR‐HIFU. The main reason(s) for ineligibility were categorized as patient‐related or lesion‐related. A random subsample of 30 ineligible patients were analyzed in detail to identify all reasons of ineligibility. Results: Overall, 57 of 741 (8%) nonspinal bone lesions were eligible for MR‐HIFU as alternative to EBRT. In total, 153 lesions (21%) in 130 patients were ineligible because of patient‐related factors, including curative treatment intent for oligo‐metastatic disease (10%), and poor performance status (8%). Of the remaining 588 bone metastases in 526 patients, 531 lesions (470 patients) were ineligible because of lesion‐related factors, including ‘lesion too extensive/advanced’ (29%), ‘(impending) pathological fracture’ (15%), ‘no moderate/severe pain from target lesion’ (11%). Proportion of ineligibility varied between centers from 70% to 96%, which was mainly attributable to differences in patient‐related factors. Within the random subsample of 30 ineligible patients, 27 patients had multiple reasons for ineligibility. Conclusion: A small proportion of patients, referred for EBRT of bone metastases, would be eligible to undergo MR‐HIFU as alternative palliation option. Taken together, patients presenting with small, localized lesions in nonspinal regions, primarily seeking pain relief without additional treatment goals are the most promising candidates for this therapy. These factors could be used to triage patients eligible for MR‐HIFU, thereby reducing unnecessary screening efforts, enhancing patient selection, and ultimately improve patient management strategies by optimizing the use of MR‐HIFU as a treatment option.

Hibernation has been proposed as a tool for human space travel. In recent years, a procedure to induce a metabolic state known as “synthetic torpor” in non-hibernating mammals was successfully developed. Synthetic torpor may not only be an efficient method to spare resources and reduce psychological problems in long-term exploratory-class missions, but may also represent a countermeasure against cosmic rays. Here we show the preliminary results from an experiment in rats exposed to ionizing radiation in normothermic conditions or synthetic torpor. Animals were irradiated with 3 Gy X-rays and organs were collected 4 h after exposure. Histological analysis of liver and testicle showed a reduced toxicity in animals irradiated in torpor compared to controls irradiated at normal temperature and metabolic activity. The expression of ataxia telangiectasia mutated (ATM) in the liver was significantly downregulated in the group of animal in synthetic torpor. In the testicle, more genes involved in the DNA damage signaling were downregulated during synthetic torpor. These data show for the first time that synthetic torpor is a radioprotector in non-hibernators, similarly to natural torpor in hibernating animals. Synthetic torpor can be an effective strategy to protect humans during long term space exploration of the solar system.

This narrative review explores the potential role of electrochemotherapy (ECT) in treating anorectal tumors, focusing on its effectiveness, feasibility, and associated toxicities. ECT, which combines chemotherapy with the application of an electric field to enhance drug uptake by tumor cells, has shown promise as a local treatment, particularly in cases where conventional therapies such as radiotherapy have been exhausted or are unsuitable. The review, conducted according to SANRA guidelines, included 18 studies, on ECT in anorectal tumors, ranging from preclinical trials in dogs to case reports and clinical studies in humans. The findings indicate that ECT can achieve high tumor overall response rates (70-100%) with minimal side effects, offering benefits such as tumor reduction and preserved organ function. These results highlight the potential of ECT to provide not only tumor reduction but also the preservation of vital organ function with a relatively low toxicity profile. However, further comparative research is necessary to substantiate its role as a standard therapeutic option. Moreover, the evidence is limited by significant heterogeneity across studies, small sample sizes, and a lack of comparative research with other local treatments like radiotherapy and cryosurgery. Consequently, while ECT appears to be a promising option, particularly for palliative care or in a neoadjuvant setting, it cannot yet be recommended as a standard treatment. Future research should focus on larger, more robust studies with standardized outcomes and explore the potential synergy between ECT and other therapies to establish its place in the treatment of anorectal tumors.

Background
It has been hypothesized that radiotherapy (RT) techniques delivering radiations to larger volumes (IMRT, VMAT) are potentially associated with a higher risk of second primary tumors. The aim of this study was to analyse the impact of RT technique (3D-CRT vs IMRT/VMAT) on the incidence of second tumors in prostate cancer (PCa) patients.
Methods
A retrospective study on 2526 previously irradiated PCa patients was performed. Patients were treated with 3D-CRT (21.3%), IMRT (68.1%), or VMAT (10.6%). Second tumors incidence was analysed in 3 categories: pelvic, pelvic and abdominal, and “any site”. The correlation with RT technique was analysed using log-rank test and Cox’s proportional hazard method.
Results
With a median follow-up of 72 months (range: 9–185), 92 (3.6%) cases of second tumors were recorded with 48 months (range: 9–152) median interval from RT. Actuarial 10-year second tumor free survival (STFS) was 87.3%. Ten-year STFS in patients treated with 3D-CRT and IMRT/VMAT was 85.8 and 84.5%, respectively (
p: .627
). A significantly higher 10-year cumulative incidence of second tumors in the pelvis was registered in patients treated with IMRT/VMAT compared to 3D-CRT (10.7% vs 6.0%;
p: .033
). The lower incidence of second pelvic cancers in patients treated with 3D-CRT was confirmed at multivariable analysis (HR: 2.42, 95%CI: 1.07–5.47,
p: .034
).
Conclusions
The incidence of second pelvic tumors after RT of PCa showed a significant correlation with treatment technique. Further analyses in larger series with prolonged follow-up are needed to confirm these results.

Purpose
The objective of this study was to determine the effect on resection rate and survival of neoadjuvant chemoradiotherapy for primarily unresectable locally advanced pancreatic carcinoma.
Methods
A systematic review of recently published literature was performed. Resection rates and survival data were derived from reports published from 2000 onwards. Only recent studies, based on radiotherapy with standard dose and fractionation, have been analyzed.
Results
Thirteen studies with a total of 510 patients met selection criteria. A resection rate of 8.3–64.2% was reported (median, 26.5%). Of the operated patients, 57.1–100% (median, 87.5%) had R0 tumor resection. Most papers reported occasional pathological complete responses (CR, 3.0–8.8%). When outcome in all patients was considered, median survival ranged from 9 to 23 (median, 13.3) months, comparing favorably with literature data based on concurrent chemoradiation alone (range, 8.6–13 months). Surprisingly, in patients with unresectable tumor at presentation, median survival after surgery ranged from 16.4 to 32.3 (median, 23.6) months.
Conclusions
The finding of a high proportion of R0 resection among all resections performed confirms the activity of neoadjuvant radiochemotherapy and should not be neglected. Based on these data, patients with unresectable pancreatic cancer without disease progression after chemoradiotherapy should be considered for radical surgery.

Introduction Biliary tract cancers (BTC) are rare and aggressive neoplasms. The current management of locally advanced or unresectable BTC is primarily based on chemotherapy (CHT) alone, linked to a median overall survival (OS) of approximately 12 months. However, international guidelines still consider concurrent chemoradiation (CRT) as an alternative treatment option. This study aims to review the current evidence on “modern” CRT for primary or recurrent unresectable BTC. Materials and Methods A comprehensive search was conducted on PubMed, Scopus, and Cochrane Library to identify relevant papers. Prospective or retrospective trials reporting outcomes after concurrent CRT of unresectable non‐metastatic, primary, or recurrent BTC were included. Only English‐written papers published between January 2010 and June 2022 were considered. Results Seventeen papers, comprising a total of 1961 patients, were included in the analysis. Among them, 11 papers focused solely on patients with primary unresectable BTC, while two papers included patients with isolated local recurrences and four papers encompassed both settings. In terms of tumor location, 12 papers included patients with intrahepatic, extrahepatic, and hilar BTC, as well as gallbladder cancer. The median CRT dose delivered was 50.4 Gy (range: 45.0–72.6 Gy) using conventional fractionation. Concurrent CHT primarily consisted of 5‐Fluorouracil or Gemcitabine. The pooled rates of 1‐year progression‐free survival (PFS) and OS were 40.9% and 56.2%, respectively. The median 1‐ and 2‐year OS rates were 63.1% and 29.4%, respectively. Grade ≥3 acute gastrointestinal toxicity ranged from 5.6% to 22.2% (median: 10.9%), while grade ≥3 hematological toxicity ranged from 1.6% to 50.0% (median: 21.7%). Conclusion Concurrent CRT is a viable alternative to standard CHT in patients with locally advanced BTC, offering comparable OS and PFS rates, along with an acceptable toxicity profile. However, prospective trials are needed to validate and further explore these findings. This is a systematic review of the current evidence on “modern” chemoradiation for primary or recurrent unresectable biliary tract cancers. We have critically compared chemoradiation outcomes with those of other treatment options, seeking to determine whether specific chemoradiation modalities provide distinct advantages in terms of treatment efficacy and patient safety. This analysis is pivotal for informing future treatment guidelines and optimizing patient care in this challenging clinical area.

Aims
This review aims to synthesize the existing literature on palliative radiotherapy (RT) delivered in two daily fractions for patients with advanced cancer, focusing on its impact on symptom alleviation, treatment tolerance, and the implications for clinical practice and future research.
Methods
An international team conducted this narrative review, adhering to SANRA guidelines. Studies published in English on palliative RT delivered in two daily fractions were selected without date restrictions. The literature search, using a combination of specific key terms, led to a comprehensive examination of relevant studies. Data on study objectives, treatment approaches, palliative effectiveness, and toxicity were extracted and qualitatively analyzed.
Results
The review included 29 publications, showing consistent efficacy in symptom reduction (63.0%–100% palliative response rate) and general tolerability across various cancer types. These studies highlighted the potential radiobiological advantages and practicality of accelerated multi-fractionated regimens, which provide rapid tumor response with reduced late toxicity risks. Furthermore, the logistical benefits of such treatments, including shorter hospital stays and minimized travel requirements, were noted as particularly valuable during challenging times such as recent pandemics.
Conclusions
The evidence supports the integration of evidence-based, accelerated-hypofractionated RT into palliative care strategies, ensuring effective symptom management with minimal patient burden. Future research should focus on comparative studies on single versus multiple-cycle treatments, optimal intervals between treatment cycles, and the integration of advanced RT techniques.
