Breast Volume Is a Predictor of Higher Heart Dose in Whole-Breast Supine Free-Breathing Volumetric-Modulated Arc Therapy Planning.

In breast cancer volumetric-modulated arc therapy (VMAT) planning, the rotation of the gantry around the target implies a greater dose spreading to the whole heart, compared to tangential-field standard treatment. A consecutive cohort of 121 breast cancer patients treated with the VMAT technique was investigated. The correlation of breast volume, heart volume and lung volume with mean heart dose (mHD) and mean and maximum LAD dose (mLAD dose, MLAD dose) was tested, and a subsequent a linear regression analysis was carried out. VMAT treatment plans from 56 left breast cancer and 65 right breast cancer patients were analyzed. For right-sided patients, breast volume was significantly correlated with mHD, mLAD and MLAD dose, while for left-sided patients, breast volume was significantly correlated with mHD and mLAD, while heart volume and lung volume were correlated with mHD, mLAD and MLAD dose. Breast volume was the only predictor of increased heart and LAD dose (p ≤ 0.001) for right-sided patients. In left-sided patients, heart and lung were also predictors of increased mHD (p = 0.005, p ≤ 0.001) and mean LAD dose (p = 0.009, p ≤ 0.001). In this study, we observed an increase in heart and LAD doses in larger-breasted patients treated with VMAT planning. In right-sided patients, breast volume was shown to be the only predictor of increased heart dose and LAD dose.

Untailored vs. Gender- and Body-Mass-Index-Tailored Skeletal Muscle Mass Index (SMI) to Assess Sarcopenia in Advanced Head and Neck Squamous Cell Carcinoma (HNSCC).

(1) Background: Sarcopenia lasting >1 year might be considered a chronic condition in many HNSCC patients. CT-scan-derived Skeletal Muscle Mass Index (SMI) is an established surrogate of sarcopenia; yet, the cut-off reported in the literature (literature-based, lb-SMI < 43.2) is mainly based on the risk of chemoradiotherapy-induced toxicity, and the optimal value to discriminate OS is under-investigated. (2) Methods: The effect on OS of the lb-SMI cutoff was compared with an untailored OS-oriented SMI cutoff obtained in a cohort of consecutive advanced HNSCC patients treated with primary chemoradiotherapy, bio-chemotherapy or chemo-immunotherapy (cohort-specific, cs-SMI cutoff). Gender- and BMI-tailored (gt-SMI and bt-SMI) cut-offs were also evaluated. Cutoff values were identified by using the maximally selected rank statistics for OS. (3) Results: In 115 HNSCC patients, the cs-SMI cutoff was 31.50, which was lower compared to the lb-SMI reported cut-off. The optimal cut-off separately determined in females, males, overweight and non-overweight patients were 46.02, 34.37, 27.32 and 34.73, respectively. gt-SMI categorization had the highest effect on survival (p < 0.0001); its prognostic value was independent of the treatment setting or the primary location and was retained in a multivariate cox-regression analysis for OS including other HNSCC-specific prognostic factors (p = 0.0004). (4) Conclusions: A tailored SMI assessment would improve clinical management of sarcopenia in chemoradiotherapy-, bio-chemotherapy- or chemo-immunotherapy-treated HNSCC patients. Gender-based SMI could be used for prognostication in HNSCC patients.

Dynomics: A Novel and Promising Approach for Improved Breast Cancer Prognosis Prediction.

Traditional imaging techniques for breast cancer (BC) diagnosis and prediction, such as X-rays and magnetic resonance imaging (MRI), demonstrate varying sensitivity and specificity due to clinical and technological factors. Consequently, positron emission tomography (PET), capable of detecting abnormal metabolic activity, has emerged as a more effective tool, providing critical quantitative and qualitative tumor-related metabolic information. This study leverages a public clinical dataset of dynamic 18F-Fluorothymidine (FLT) PET scans from BC patients, extending conventional static radiomics methods to the time domain-termed as 'Dynomics'. Radiomic features were extracted from both static and dynamic PET images on lesion and reference tissue masks. The extracted features were used to train an XGBoost model for classifying tumor versus reference tissue and complete versus partial responders to neoadjuvant chemotherapy. The results underscored the superiority of dynamic and static radiomics over standard PET imaging, achieving accuracy of 94% in tumor tissue classification. Notably, in predicting BC prognosis, dynomics delivered the highest performance, achieving accuracy of 86%, thereby outperforming both static radiomics and standard PET data. This study illustrates the enhanced clinical utility of dynomics in yielding more precise and reliable information for BC diagnosis and prognosis, paving the way for improved treatment strategies.

Total neoadjuvant therapy for the treatment of locally advanced rectal cancer: a systematic minireview.

Colorectal carcinoma is the second leading cause of cancer-related deaths, and indeed, rectal cancer accounting for approximately one third of newly diagnosed patients. Gold standard in the treatment of rectal cancer is a multimodality approach, aiming at a good control of the local disease. Distant recurrences are the major cause of mortality. Currently, Locally Advanced Rectal Cancer (LARC) patients undergo a combined treatment of chemotherapy and radiotherapy, followed by surgery. Eventually, more chemotherapy, namely adjuvant chemotherapy (aCT), may be necessary. Total Neoadjuvant Therapy (TNT) is an emerging approach aimed to reduce distant metastases and improve local control. Several ongoing studies are analyzing whether this new approach could improve oncological outcomes. Published results were encouraging, but the heterogeneity of protocols in use, makes the comparison and interpretation of data rather complex. One of the major concerns regarding TNT administration is related to its effect on larger and more advanced cancers that might not undergo similar down-staging as smaller, early-stage tumors. This minireview, based on a systematic literature search of randomized clinical trials and meta-analysis, summarizes current knowledge on TNT. The aim was to confirm or refute whether or not current practice of TNT is based on relevant evidence, to establish the quality of that evidence, and to address any uncertainty or variation in practice that may be occurring. A tentative grouping of general study characteristics, clinical features and treatments characteristics has been undertaken to evaluate if the reported studies are sufficiently homogeneous in terms of subjects involved, interventions, and outcomes to provide a meaningful idea of which patients are more likely to gain from this treatment.

Factors Predicting Pathological Response to Neoadjuvant Chemoradiotherapy in Rectal Cancer: The Experience of a Single Institution with 269 Patients (STONE-01).

AIMS: The aim of this study was to define a potential benefit of pathological complete response rate (pCR) and downstaging rate after neoadjuvant chemoradiotherapy (CRT) in relation to treatment and patient factors in locally advanced rectal cancer. METHODS: We performed a retrospective cohort study. Patients were divided according to chemotherapy regimens concurrent to radiotherapy (1-drug vs. 2-drug) and according to the time interval between the end of CRT and surgery (≤8 weeks vs. >8 weeks), as well as in relation to specific relevant clinical factors. Logistic regression was used to estimate the independent factors for pCR and downstaging. RESULTS: 269 patients were eligible for this study. Overall, pCR and downstaging rates were 26% and 75.4%, respectively. Univariate analysis showed that female gender (p = 0.01) and time to surgery >8 weeks (p = 0.04) were associated with pCR; age > 70 years (p = 0.05) and time to surgery >8 weeks (p = 0.002) were correlated to downstaging. At multivariate analysis, interval time to surgery of >8 weeks was the only independent factor for both pCR and downstaging (p = 0.02; OR: 0.5, CI: 0.27-0.93 and p = 0.003; OR: 0.42, CI: 0.24-0.75, respectively). CONCLUSIONS: This study indicates that, in our population, an interval time to surgery of >8 weeks is an independent significant factor for pCR and downstaging. Further prospective studies are needed to define the best interval time.

Resilience in Radiotherapy Services During the COVID-19 Emergency: Collaboration Between the Regional Radiation Oncology Departments of Lazio, Abruzzo and Molise.

AIM: Radiation therapy is a cornerstone of oncological treatment and oncological patients show greater risk of developing complications related to COVID-19 infection. Stringent social restrictions have ensured a significant reduction in the spread of the virus, but also gave rise to a number of critical issues for radiation oncology wards. For this reason, the Directors of the Radiation Oncology Departments (RODs) of Lazio, Abruzzo and Molise regions shared their experience and ideas in order to create a common document that may assist in facing the negative impacts of the pandemic on radiation oncology wards and patients. PATIENTS AND METHODS: The study was conducted according to the Estimate-Talk-Estimate method. Five issues were proposed and rated. Among approved issues, statements were proposed anonymously, then harmonized and finally voted on according to a Likert scale from 1 to 9. Those for which an agreement of 7-9 was observed were finally approved. RESULTS: The document was developed with 42 statements dealing about safety measures for patients and staff, organization of clinical and work activities, usage of Information Technology systems for meetings/smart working. An agreement was recorded for 34 statements. CONCLUSION: This document sets out some recommendations for RODs and can provide valuable management information for Oncological Radiotherapy wards.

The Italian Association of Radiotherapy and Oncology Recommendation for Breast Tumor Recurrence: Grades of Recommendation, Assessment, Development and Evaluation Criteria.

Salvage mastectomy is currently considered the standard of care for ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) and postoperative radiotherapy (RT). Alternative treatment options for these patients, such as a second BCS followed by repeated RT, have been suggested. The panel of the Italian Association of Radiotherapy and Clinical Oncology developed clinical recommendations for second BCS followed by re-irradiation over mastectomy alone for women with IBTR using the Grades of Recommendation, Assessment, Development, and Evaluation methodology and the evidence to decision framework. The following outcomes were identified by the panel: locoregional control, metastasis-free survival, overall survival, and cancer-specific survival; acute and late toxicity, specific late toxicity, second locoregional tumor, and death related to treatment. An Embase and PubMed literature search was performed by two independent authors. Five retrospective observational studies were eligible for inclusion in the present analysis. According to the reports in the literature and our analysis, the advantages of second quadrantectomy and re-irradiation (re-QUART) outweigh its side effects, with overall good rates of survival and adequate toxicity without increasing costs. Given the very low level of evidence, the panel stated that a second BCS plus re-irradiation can be considered as an alternative to salvage mastectomy for selected patients with IBTR.

Survival and toxicity of weekly cisplatin chemoradiotherapy versus three-weekly cisplatin chemoradiotherapy for head and neck cancer: A systematic review and meta-analysis endorsed by the Italian Association of Radiotherapy and Clinical Oncology (AIRO).

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.

Sequential chemo-hypofractionated RT versus concurrent standard CRT for locally advanced NSCLC: GRADE recommendation by the Italian Association of Radiotherapy and Clinical Oncology (AIRO).

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.

Adjuvant radiotherapy and radioiodine treatment for locally advanced differentiated thyroid cancer: systematic review and meta-analysis.

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.

Treatment of muscle-invasive bladder cancer in patients without comorbidities and fit for surgery: Trimodality therapy vs radical cystectomy. Development of GRADE (Grades of Recommendation, Assessment, Development and Evaluation) recommendation by the Italian Association of Radiotherapy and Clinical Oncology (AIRO).

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.

Effects of abiraterone acetate plus prednisone on bone turnover markers in chemotherapy-naïve mCRPC patients after ADT failure: A prospective analysis of the italian real-world study ABITUDE.

BACKGROUND: Bone remodeling is disrupted in metastatic disease, which affects > 70% of metastatic castration-resistant prostate cancer (mCRPC) patients. As a result, abnormal levels of specific bone turnover biomarkers (BTMs) are released. In this prospective ancillary analysis of the Italian real-world study ABITUDE, four markers were measured during abiraterone acetate plus prednisone (AAP) treatment in chemotherapy-naïve mCRPC men failing androgen-deprivation therapy. METHODS: Patients were enrolled if a blood sample was obtained before the first administration of abiraterone (baseline); ad-hoc blood samples were withdrawn during routine tests after 3, 6, and 12 months. A centralized lab measured bone alkaline phosphatase (BALP, osteoblast activity marker), type-I collagen-C-telopeptide (CTX-1, bone resorption marker), parathyroid hormone (PTH) and vitamin D (vitD). At each time point, intra-patient variations vs baseline were compared by the signed-rank test (statistical significance: P-value < 0.05). RESULTS: Of 481 patients enrolled in ABITUDE, 186 (median age: 76 [range: 53-93] years) met the substudy criteria: 74.7% had bone metastases, 11.8% were on bone-targeted therapies (BTT) and 14.0% on vitD supplementation. BALP decreased significantly at month 6 (P = 0.0010) and 12 (P < 0.0001) and CTX-1 at month 6 (P = 0.0028); PTH increased at month 3 (P < 0.0001); no significant difference in vitD levels was observed. Similar findings were observed in BTT-untreated patients. The reduction in BALP and CTX-1 levels was more pronounced in patients with than without bone metastases; in the latter group, no significant variation in BALP and CTX-1 levels was observed. CONCLUSIONS: AAP seems to exert an effect on the microenvironment of metastatic but not of normal bone, which likely contributes to its antitumoral activity.

Loco-regional adjuvant radiation therapy in breast cancer patients with positive axillary lymph-nodes at diagnosis (CN2) undergoing preoperative chemotherapy and with complete pathological lymph-nodes response. Development of GRADE (Grades of recommendation, assessment, Development and Evaluation) recommendation by the Italian Association of radiation therapy and Clinical Oncology (AIRO).

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, lymphedema and cardiac events. CONCLUSIONS: Because of the limitations due to the small number of studies and heterogeneity in the analysis, the present study does not allow to draw any definitive conclusion, highlighting the need for well-controlled trials to determine the effect of loco-regional RT in patients with cN2 having a pathological complete response in the axillary nodes after preoperative chemotherapy.

Long-Term Results of a Prospective Phase 2 Study on Volume De-Escalation in Neoadjuvant Chemoradiotherapy of Rectal Cancer.

PURPOSE: In the current study, we evaluated whether neoadjuvant chemoradiotherapy with reduced treatment volumes due to the exclusion of elective pelvic nodal irradiation is a feasible strategy for selected patients with locally advanced rectal cancer. METHODS AND MATERIALS: Patients with T2 low-lying/T3, N0-N1 rectal lesions without evidence of disease in the lateral lymph nodes were prospectively recruited. All patients underwent pretreatment testing, including computed tomography imaging of the chest, abdomen, and pelvis with intravenous contrast, pelvic magnetic resonance imaging with intravenous contrast, and 18-fluorodeoxyglucose positron emission/computed tomography. The clinical target volume included the primary tumor and the mesorectum with vascular supply containing the perirectal and presacral nodes, with the upper border at the S2/S3 interspace. The total radiation dose was 50.4 Gy, and fluoropyrimidine-based chemotherapy was associated concomitantly. The primary endpoint of the study was the reduction of gastrointestinal (GI) toxicity, and the secondary endpoints were pathologic complete response, local control, overall survival, and disease-free survival. RESULTS: Fifty-two patients (30 men, 22 women) with a median age of 67 years (range, 45-85 years) were enrolled in the study. Acute grade 3 GI toxicity was 7.6%, and there were no cases of grade 4 toxicity. Three patients (5.7%) developed a local recurrence. No relapse occurred in the lateral lymph nodes. The local control rate at 5 years was 96.1%. With a median follow-up time of 72.9 months (range, 2.5-127.6 months), the 3- and 5-year overall survival rates were 89.4% and 87%, respectively. The 3- and 5-year disease-free survival rates were 82.4% and 82.4%, respectively. CONCLUSIONS: De-escalation of radiation therapy target volume reduces GI side effects without compromising efficacy in patients with rectal cancer. These results cannot be clearly extended to high-risk disease and need further evaluation in future randomized trials.

Consensus statements on ablative radiotherapy for oligometastatic prostate cancer: A position paper of Italian Association of Radiotherapy and Clinical Oncology (AIRO).

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.

Combining abiraterone and radiotherapy in metastatic castration-resistant prostate cancer: a review of current evidence.

Prostate cancer is the second most frequent cancer worldwide, with a very high rate of progression despite treatment. The most aggressive form of the disease is known as castration-resistant prostate cancer, which carries a poor prognosis. We reviewed available literature regarding the combination of abiraterone acetate antihormonal drug and ablative radiation therapy for the treatment of metastatic castration-resistant prostate cancer. This dual treatment may enhance the effects of second-line hormonal therapy, as radiotherapy renders cancer cells more prone to immune-mediated cytotoxicity. Moreover, radiotherapy exerts its effect both on directly irradiated cells and on other distant tissues, with an abscopal effect, already demonstrated in other solid tumors. This combination treatment is safe and effective, with few adverse events. Moreover, it is of paramount importance in patients with oligoprogression of the primary disease, when current guidelines recommend continuing abiraterone treatment. Ablative radiation therapy is a noninvasive, nontoxic treatment with very high efficacy on local tumor growth control. In the available literature, the combination of radiation therapy and abiraterone acetate has prolonged both overall survival and progression-free survival, with a positive impact also on locoregional recurrence and distant metastases.

Histologic transformation to small-cell lung cancer following gefitinib and radiotherapy in a patient with pulmonary adenocarcinoma.

INTRODUCTION: Targeted therapies against epidermal growth factor receptor (EGFR) have revolutionized the treatment of a subset of lung adenocarcinomas that have EGFR-activating mutations; however, all patients treated with EGFR tyrosine kinase inhibitors (TKIs) ultimately develop resistance. Histologic transformation of EGFR-mutant adenocarcinoma to small cell lung cancer (SCLC) is a resistance mechanism rarely reported in the literature. CASE PRESENTATION: We describe the case of a woman with metastatic lung cancer adenocarcinoma with mutated EGFR with an initial response to gefitinib and radiation therapy, who progressed after 18 months due to the development of a resistance mechanism. The new biopsy performed after progression highlighted histologic transformation to SCLC, while maintaining the original EGFR mutation. CONCLUSIONS: To better identify patients who progress after TKIs and radiation therapy, it is important to perform tumor rebiopsy and collect data to study mechanisms of acquired EGFR TKI resistance.

Multidisciplinary teams for the proper management of patients with genitourinary tumors: When topics set scientific societies' agenda.

INTRODUCTION: The multidisciplinary management of oncologic patients is identified as the bottom line element of quality in tumor care. METHODS: In 2015, 7 Italian scientific societies representing the specialists involved in the diagnosis and treatment of genitourinary tumors joined efforts in the Italian uro-oncologic multidisciplinary teams (MDTs) project. The aims were to promote the reorganization of genitourinary cancer care, switching to a multidisciplinary approach, reach a consensus on the core elements for the setup of MDTs in genitourinary oncology, and support health policy makers and managers in remodeling of the assistance and care of uro-oncologic patients on a national level. RESULTS: The first activity was the setup of 5 working groups, given the task of exploring selected topics: general principles, organization of MDTs, minimal requirements, economic evaluation, and relations with authorities. The groups participated in the writing of a document that was approved by the scientific societies and published on their web sites. Moreover, a few items summarizing the extensive document were approved in the first MDT Consensus Conference held in Milan in December 2015. CONCLUSIONS: The experience of this initial phase led to the opening of the team to other professionals and societies, in line with a correct management of patients with genitourinary tumors, which need a multidisciplinary as well as a multiprofessional approach with emerging techniques and procedures, and with a new project work package on genitourinary paths of care and indicators.
