Objective: To perform a meta-analysis to determine the effect of loco-regional radiation therapy (RT) compared to no loco-regional RT for operated patients in clinical stage cN2 breast cancer at diagnosis and ypN0 after preoperative chemotherapy (PST). Material and Methods: Eligible studies were identified through a systematic search of the medical literature performed independently by two researchers using a validated search strategy. An electronic search of Medline via PubMed and Embase (Breast cancer AND preoperative chemotherapy AND radiation therapy) was conducted with no language or publication status restrictions. The effect of loco-regional RT on overall (OS), disease free (DFS), loco-regional recurrence-free (LRRFS) survival and local recurrence was evaluated. An electronic search of Medline via PubMed and Embase (Toxicity AND radiation therapy breast cancer AND preoperative therapy; toxicity AND breast surgery AND preoperative chemotherapy) was conducted for outcomes of harm: major acute and late skin toxicity, lymphedema and cardiac events. Results: Of 333 studies identified, 4 retrospective studies reporting on a total of 1107 patients were included in the meta-analysis. Six and 3 reported data of acute and late skin toxicity, while 2 studies provided information on cardiac events. Pooled results showed no difference in terms of hazard ratio for loco-regional RT versus no loco-regional RT [hazard ratio (HR) = 0.82, 95% confidence interval (CI) 0.63–1.68]. Loco-regional RT was associated with an OS benefit in the subgroup analysis: IIIB-C (loco-regional RT 79.3% vs no loco-regional RT 71.2%, p = 0.027) and T3-T4 (loco-regional RT 82.6% vs no loco-regional RT 76.6%, p = 0.025). No difference was shown in terms of 5-year DFS (loco-regional RT 91.2% vs no loco-regional RT 83%, p = 0.441) and LRRFS (loco-regional RT 98.1% vs no loco-regional RT 92.3%, p = 0.148). There was no significant difference between the groups in terms of acute and late skin toxicities

Introduction: Almost 30% of non-small cell lung cancer (NSCLC) patients have locally advanced-stage disease. In this setting, definitive radiotherapy concurrent to chemotherapy plus adjuvant immunotherapy (cCRT + IO) is the standard of care, although only 40% of these patients are eligible for this approach. Aims: A comparison between cCRT and hypofractionated radiotherapy regimens (hypo-fx RT) with the addition of sequential chemotherapy (sCHT) could be useful for future combinations with immunotherapy. We developed a recommendation about the clinical question of whether CHT and moderately hypo-fx RT are comparable to cCRT for locally advanced NSCLC Materials and methods: The panel used GRADE methodology and the Evidence to Decision (EtD) framework. After a systematic literature search, five studies were eligible. We identified the following outcomes: progression-free survival (PFS), overall survival (OS), freedom from locoregional recurrence (FFLR), deterioration of quality of life (QoL), treatment-related deaths, severe G3–G4 toxicity, late pulmonary toxicity G3–G4, and acute esophageal toxicity G3–G4. Results: The probability of OS and G3–G4 late lung toxicity seems to be worse in patients submitted to sCHT and hypo-fx RT. The panel judged unfavorable the balance benefits/harms. Conclusions: The final recommendation was that sCHT followed by moderately hypo-fx RT should not be considered as an alternative to cCRT in unresectable stage III NSCLC patients.

Background: Treatment for locally advanced differentiated thyroid cancer is surgery followed by radioiodine while the role of adjuvant external beam radiotherapy (EBRT) is debated. Methods: The panel of the Italian Association of Radiotherapy and Clinical Oncology developed a clinical recommendation on the addition of EBRT to radioiodine after surgery for locally advanced differentiated thyroid cancer by using the Grades of Recommendation, Assessment, Development, and Evaluation methodology and the Evidence to Decision framework. A systematic review with meta-analysis about this topic was conducted with a focus on outcome of benefits and toxicity. Results: Locoregional control was improved by EBRT while no considerable toxicity impact was reported. Conclusion: The panel judged uncertain the benefit/harms balance; final recommendation was conditional both for EBRT + radioiodine and radioiodine alone in the adjuvant setting.

Aim: To compare trimodality therapy (TMT) versus radical cystectomy (RC) and develop GRADE (Grades of Recommendation, Assessment, Development and Evaluation) Recommendation by the Italian Association of Radiotherapy and Clinical Oncology (AIRO) for treatment of muscle-invasive bladder cancer (MIBC). Material and Methods: Prospective and retrospective studies comparing TMT and RC for MIBC patients were included. Qualitative and quantitative evaluation of evidence was made. Results: Ten studies were included in the analysis. Pooled analysis showed salvage cystectomy and pathological complete response rates after TMT of 12 % and 72–77.5 %, respectively. Pooled rates of G3-G4 GU toxicity and serious toxicity rate were 18 vs 3% and 45 vs 29 % for patients undergoing TMT vs RC, respectively. The panel assessed a substantial equivalence in terms of OS and CSS at 5 years between TMT and RC. Conclusions: TMT could be suggested as an alternative treatment to RC in non-metastatic MIBC patients, deemed fit for surgery.

Background. Regular treatment to prevent bleeding and consequent joint deterioration (prophylaxis) is the standard of care for persons with severe hemophilia A, traditionally based on intravenous infusions of the deficient clotting FVIII concentrates (CFCs). In recent years, extended half‐life (EHL) CFCs and the non‐replacement agent emicizumab, subcutaneously administered, have reduced the treatment burden. Methods. To compare and integrate the opinions on the different therapies available, eight hemophilia specialists were involved in drafting items of interest and relative statements through the Estimate‐Talk‐Estimate (ETE) method (“mini‐Delphi”), in this way reaching consensus. Results. Eighteen items were identified, then harmonized to 10, and a statement was generated for each. These statements highlight the importance of personalized prophylaxis regimens. CFCs, particularly EHL products, seem more suitable for this, despite the challenging intravenous (i.v.) administration. Limited real‐world experience, particularly in some clinical settings, and the lack of evidence on long‐term safety and efficacy of non‐replacement agents, require careful individual risk/benefit assessment and multidisciplinary data collection. Conclusions. The increased treatment options extend the opportunities of personalized prophylaxis, the mainstay of modern management of hemophilia. Close, long‐term clinical and laboratory follow‐up of patients using newer therapeutic approaches by specialized hemophilia treatment centers is needed.

Purpose: To evaluate efficacy and toxicity of weekly cisplatin chemoradiotherapy versus three-weekly cisplatin chemoradiotherapy and identify differences in clinical outcomes and severe toxicity rate. Methods: PICOS/PRISMA methods were used to identify studies on PubMed, EMBASE and Cochrane Library, 2005–2019. Results: Six randomized clinical trials (554 patients) were identified. Weekly cisplatin was not associated with significant overall survival (HR 1.13, 95 % CI 0.84–1.51) and progression-free survival (HR 1.23, 95 %CI 0.91–1.65) improvement compared with three-weekly regimen. Severe acute toxicity (RR 0.95), treatment compliance to chemotherapy (RR 1.67) and radiotherapy (RR 0.61) were similar between regimens. Conclusion: Weekly cisplatin is not associated with better clinical outcomes compared to three-weekly cisplatin. Three-weekly cisplatin chemoradiotherapy should be considered the standard approach in the management of locally advanced head and neck cancer. Methodologically robust RCTs designs are needed to improve the quality of evidence. Differences on long-term toxicity and cost-effectiveness remain to be tested.

Purpose: To perform a systematic review of the current level of evidence on post-operative management following brain metastasectomy (namely: adjuvant stereotactic radiosurgery, whole brain radiotherapy or observation), and to propose a GRADE-based dedicated recommendation to inform Radiation Oncologists’ clinical practice. Methods: A panel of expert Radiation Oncologists from the Italian Association of Radiotherapy and Clinical Oncology had defined the search question per the PICO methodology. Electronic databases were independently screened; the Preferred Reporting Items for Systematic Reviews and Meta-Analyses was adopted. The individual and pooled hazard ratios with 95% confidence intervals (CI), as well as the pooled risk ratio (RR) were calculated using a fixed- or random-effects model. Results: Eight full-texts were retrieved: six retrospective studies and two randomized clinical trials. Outcomes of benefit and damage were analyzed for SRS + observation (PICO A) and SRS + WBRT. SRS allowed for increased rates of local control when compared to both observation and WBRT, while evidence was less conclusive for distant brain control, leptomeningeal disease control and overall survival. In the SRS, the incidence of severe radionecrosis was higher as compared to WBRT, despite neurocognitive deterioration rates were lower. Overall, SRS seems to favorably compare with observation and whole brain RT, despite the level of evidence for the recommendation was low and very low, respectively. Conclusion: Despite low level of evidence, the panel concluded that the risk/benefit ratio probably favors adjuvant SRS as compared to the observation and whole brain RT as adjuvant treatments following brain metastasectomy (5 votes/5 participants, 100% attendance).

Background: The aim of this study was to record the opinions of Italian oncologists about the use of oral vinorelbine administered metronomically in patients with advanced breast cancer. Methods: A series of meetings were held throughout Italy, and participants were asked how much they agreed with each of the several statements. Results: The majority of oncologists agreed that the concept of the minimum biologically effective dose should be used for drugs administered metronomically. Over 50% agreed that metronomic vinorelbine is an option in first-line chemotherapy for patients with advanced breast cancer, including those with a terminal illness and the elderly, as well as in young and fit patients. Just over one-third of experts agreed that a combination of two chemotherapy agents instead of one is not desirable in metastatic breast cancer because of increased toxicity. Most experts agreed that the main aim of a first-line therapy is to control the disease over time and to preserve quality of life. Conclusion: Metronomically administered oral vinorelbine, either as monotherapy or in combination with other drugs, is effective in the long-term treatment of patients with advanced breast cancer. The clinical profiles of patients should be carefully considered to determine the appropriate treatment strategy.

Background: The availability of a number of agents that are efficacious in patients with metastatic prostate cancer (mPC) has led to them being used sequentially, and this has prolonged patient survival. However, in order to maximize their efficacy, clinicians need to be able to obtain a reliable picture of disease evolution by means of monitoring procedures. Methods: As the intensive monitoring protocols used in pivotal trials cannot be adopted in everyday clinical practice and there is no agreement among the available guidelines, a multidisciplinary panel of Italian experts met to develop recommendations for monitoring mPC patients using a modified Delphi method. Results: The consensus project considered methods of clinically, radiographically, and biochemically monitoring patients with metastatic hormone-sensitive and metastatic castration-resistant prostate cancer undergoing chemotherapy and/or hormonal treatment. The panelists also considered the methods and timing of monitoring castration levels, bone health, and the metabolic syndrome during androgen deprivation therapy. Conclusions: The recommendations, which were drawn up by experts following a formal and validated consensus procedure, will help clinicians face the everyday challenges of monitoring metastatic prostate cancer patients.

The prognosis for patients with locally advanced or metastatic breast cancer (mBC) remains poor, with a median survival of 2-4 years. About 10% of newly diagnosed breast cancer patients present with metastatic disease, and 30%-50% of those diagnosed at earlier stages will subsequently progress to mBC. In terms o f ongoing management for advanced/metastatic breast cancer after failure of hormonal therapy, there is a high medical need for new treatment options that prolong the interval to the start of intensive cytotoxic therapy, which is often associated with potentially serious side effects and reduced quality of life. Oral chemotherapeutic agents such as capecitabine and vinorelbine have demonstrated efficacy in patients with mBC, with prolonged disease control and good tolerability. Use of oral chemotherapy reduces the time and cost associated with treatment and is often more acceptable to patients than intravenous drug delivery. Metronomic administration of oral chemotherapy is therefore a promising treatment strategy for some patients with mBC and inhibits tumor progression via multiple mechanisms of action. Ongoing clinical trials are investigating metronomic chemotherapy regimens as a strategy to prolong disease control with favorable tolerability. This article provides an overview of metronomic chemotherapy treatment options in mBC, with perspectives on this therapy from a panel of experts.

Oligometastatic prostate cancer comprises a wide spectrum of conditions, ranging from de novo oligometastatic cancer at diagnosis to oligometastatic castration-resistant disease, which are distinct entities in terms of biology and prognosis. In order to clarify and standardize the clinical role of ablative radiotherapy in oligometastatic prostate cancer, the Italian Association of Radiotherapy and Clinical Oncology (AIRO) formed an expert panel to review the current literature and develop a formal consensus. Oligometastatic prostate cancer was defined as the presence of up to three metastatic lesions involving bones or nodes outside pelvis. Thereafter, four clinical scenarios were explored: metastatic castration-sensitive disease at diagnosis and after primary treatment, and metastatic castration-resistant disease at diagnosis and during treatment, where the role of ablative radiotherapy was defined either in conjunction with systemic therapy or as the only treatment in selected cases. This paper summarizes the current literature about these issues and the proposed recommendations.

In thisaper, weresent an approach to evaluate the hydrological alterations of a temporary river. In these rivers, it is expected that anthropogenicressures largely modify low-flow components of the flow regime with consequences for aquatic habitat and diversity in invertebrate species. First, by using a simple hydrological index (IARI) river segments of the Celone stream (southern Italy) whose hydrological regime is significantly influenced by anthropogenic activities have been identified. Hydrological alteration has been further classified through the analysis of two metrics: the degree (Mf) and theredictability of dry flow conditions (Sd6). Measured streamflow data were used to calculate the metrics inresent conditions (impacted). Given the lack of data fromristine conditions, simulated streamflow time series were used to calculate the metrics in reference conditions. The Soil and Water Assessment Tool (SWAT) model was used to estimate daily natural streamflow. Hydrological alterations associated with water abstractions,oint discharges and theresence of a reservoir were assessed by comparing the metrics (Mf, Sd6) before and after the impacts. The results show that the hydrological regime of the river segment located in the upperart of the basin is slightly altered, while the regime of the river segment downstream of the reservoir is heavily altered. This approach is intended for use with ecological metrics in defining the water quality status and inlanning streamflow management activities.
