The role of radiation therapy in the multidisciplinary management of male breast cancer: A systematic review and meta-analysis on behalf of the Clinical Oncology Breast Cancer Group (COBCG).

Male breast cancer (MaBC) is an uncommon disease. It is generally assimilated to post-menopausal female breast cancer and treated accordingly. However, the real impact of radiation therapy, after both mastectomy and breast conservation, has yet to be established.

Locally advanced cervical cancer: how the improvement in techniques in external beam radiotherapy and brachytherapy impacts on survival outcomes and long-term toxicities.

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.

Axillary Management in Breast Cancer Patients Undergoing Upfront Surgery: Results from a Nationwide Survey on Behalf of the Clinical Oncology Breast Cancer Group (COBCG) and the Breast Cancer Study Group of the Italian Association of Radiotherapy and Clinical Oncology (AIRO).

Background: We assessed the current practice concerning the axillary management of breast cancer (BC) patients undergoing upfront surgery among radiation oncologists (ROs) practising in Italy.

Methods: An online survey via SurveyMonkey (including 21 questions) was distributed amongst ROs in Italy through personal contacts and the Italian Association for Radiotherapy and Clinical Oncology (AIRO) network from August to September 2022. We particularly focused on the emerging omission of axillary lymph node dissection (ALND) in the presence of 1-2 sentinel node-positive patients and the consequent change in the role of regional nodal irradiation (RNI).

AIRO Breast Cancer Group .

Introduction: Breast cancer is the most common tumor in women and represents the leading cause of cancer death. Radiation therapy plays a key-role in the treatment of all breast cancer stages. Therefore, the adoption of evidence-based treatments is warranted, to ensure equity of access and standardization of care in clinical practice.

Ways to improve breast cancer patients' management and clinical outcome: The 2020 Assisi Think Tank Meeting.

We report on the third Assisi Think Tank Meeting (ATTM) on breast cancer, a brainstorming project which involved European radiation and clinical oncologists who were dedicated to breast cancer research and treatment. Held on February 2020, the ATTM aimed at identifying key clinical questions in current clinical practice and "grey" areas requiring research to improve management and outcomes. Before the meeting, three key topics were selected: 1) managing patients with frailty due to either age and/or multi-morbidity; 2) stereotactic radiation therapy and systemic therapy in the management of oligometastatic disease; 3) contralateral breast tumour prevention in BCRA-mutated patients.

Prognostic role of baseline F-FDG pet/CT in squamous cell carcinoma of the paranasal sinuses.

Background: To retrospectively investigate the prognostic role of baseline F-FDG PET/CT in squamous cell carcinoma (SCC) of the paranasal sinuses.

Methods: Clinical features and PET/CT semiquantitative parameters of 49 patients were collected. Anova and Kruskall-Wallis tests were used to assess the relationship between these parameters.

Stratification of Oligometastatic Prostate Cancer Patients by Liquid Biopsy: Clinical Insights from a Pilot Study.

We propose a pilot, prospective, translational study with the aim of identifying possible molecular markers underlying metastatic prostate cancer (PC) evolution with the use of liquid biopsy. Twenty-eight castrate sensitive, oligometastatic PC patients undergoing bone and/or nodal stereotactic body radiotherapy (SBRT) were recruited. Peripheral blood samples were collected before the commencement of SBRT, then they were processed for circulating cell free DNA (cfDNA) extraction.

Prognostic Role of Pre-Treatment Metabolic Parameters and Sarcopenia Derived by 2-[F]-FDG PET/CT in Elderly Mantle Cell Lymphoma.

The goal of this retrospective study was to analyze and compare the prognostic role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (2-[F]-FDG PET/CT) features and sarcopenia, estimated by CT of PET in elderly (≥65 years) Mantle Cell Lymphoma (MCL). We recruited 53 patients, who underwent pre-treatment 2-[F]-FDG PET/CT and end-of-treatment PET/CT, and the main semiquantitative parameters were calculated. Sarcopenia was measured as skeletal muscle index (SMI, cm/m) and derived by low-dose PET/CT images at the L3 level.

Comparison between Two Different Scanners for the Evaluation of the Role of F-FDG PET/CT Semiquantitative Parameters and Radiomics Features in the Prediction of Final Diagnosis of Thyroid Incidentalomas.

The aim of this study was to compare two different tomographs for the evaluation of the role of semiquantitative PET/CT parameters and radiomics features (RF) in the prediction of thyroid incidentalomas (TIs) at F-FDG imaging. A total of 221 patients with the presence of TIs were retrospectively included. After volumetric segmentation of each TI, semiquantitative parameters and RF were extracted.

Biological Bases of Immune-Related Adverse Events and Potential Crosslinks With Immunogenic Effects of Radiation.

Immune checkpoint inhibitors have gained an established role in the treatment of different tumors. Indeed, their use has dramatically changed the landscape of cancer care, especially for tumor types traditionally known to have poor outcomes. However, stimulating anticancer immune responses may also elicit an unusual pattern of immune-related adverse events (irAEs), different from those of conventional chemotherapy, likely due to a self-tolerance impairment featuring the production of autoreactive lymphocytes and autoantibodies, or a non-specific autoinflammatory reaction.

Breast reconstruction and radiation therapy: An Italian expert Delphi consensus statements and critical review.

Breast conserving surgery (BCS) plus radiation therapy (RT) or mastectomy have shown comparable oncological outcomes in early-stage breast cancer and are considered standard of care treatments. Postmastectomy radiation therapy (PMRT) targeted to both the chest wall and regional lymph nodes is recommended in high-risk patients. Oncoplastic breast conserving surgery (OBCS) represents a significant recent improvement in breast surgery.

Almost one year of COVID-19 pandemic: how radiotherapy centers have counteracted its impact on cancer treatment in Lombardy, Italy. CODRAL/AIRO-L study.

Lombardy has represented the Italian and European epicenter of the coronavirus disease 2019 (COVID-19) pandemic. Although most clinical efforts within hospitals were diverted towards the care of virally infected patients, therapies for patients with cancer, including radiotherapy (RT), have continued. During both the first and second pandemic waves, several national and regional organizations provided Italian and Lombardian RT departments with detailed guidelines aimed at ensuring safe treatments during the pandemic.

Comparing hypofractionated and conventionally fractionated whole breast irradiation for patients with ductal carcinoma in situ after breast conservation: a propensity score-matched analysis from a national multicenter cohort (COBCG-02 study).

Background And Purpose: Randomized trials confirmed the efficacy and the safety of hypofractionated whole breast irradiation (HF-WBI) in patients with early-stage breast cancer. However, the role of HF-WBI in patients with DCIS after breast conserving surgery has not yet been clearly established in prospective randomized trials. The aim of this study was to evaluate if HF-WBI can be considered comparable to conventionally fractionated (CF)-WBI in DCIS patients.

Radiotherapy for the treatment of solitary plasmacytoma: 7-year outcomes by a mono-institutional experience.

Objectives: Solitary plasmacytoma (SP) is characterized by a single mass of clonal plasma cells. Definitive RT can result in long-term local control of the SP. Due to the small number of patients and narrow range of doses, phase III randomized trials are lacking.

Back to (new) normality-A CODRAL/AIRO-L survey on cancer radiotherapy in Lombardy during Italian COVID-19 phase 2.

Background: Italy experienced one of the world's severest COVID-19 outbreak, with Lombardy being the most afflicted region. However, the imposed safety measures allowed to flatten the epidemic curve and hence to ease the restrictions and inaugurate, on the 4th of May 2020, the Italian phase (P) 2 of the pandemic. The present survey study, endorsed by CODRAL and AIRO-L, aimed to assess how radiotherapy (RT) departments in Lombardy have dealt with the recovery.

A single-center retrospective safety analysis of cyclin-dependent kinase 4/6 inhibitors concurrent with radiation therapy in metastatic breast cancer patients.

Cyclin dependent kinases 4/6 (CDK4/6) inhibitors gained an essential role in the treatment of metastatic breast cancer. Nevertheless, data regarding their use in combination with radiotherapy are still scarce. We performed a retrospective preliminary analysis of breast cancer patients treated at our Center with palliative radiation therapy and concurrent CDK4/6 inhibitors.

Two months of radiation oncology in the heart of Italian "red zone" during COVID-19 pandemic: paving a safe path over thin ice.

Background: Coronavirus Disease 2019 (COVID-19) pandemic had an overwhelming impact on healthcare worldwide. Outstandingly, the aftermath on neoplastic patients is still largely unknown, and only isolated cases of COVID-19 during radiotherapy have been published. We will report the two-months experience of our Department, set in Lombardy "red-zone".

Disease course of lung oligometastatic colorectal cancer treated with stereotactic body radiotherapy.

Purpose: Stereotactic body radiotherapy (SBRT) or stereotactic ablative radiotherapy (SABR) has been shown to increase survival rates in oligometastatic disease (OMD), but local control of colorectal metastases remains poor. We aimed to explore the natural course of oligometastatic colorectal cancer and to investigate how SBRT of lung metastases can delay the progression to polymetastatic disease (PMD).

Methods: 107 lung oligometastases in 38 patients were treated with SBRT at a single institution.

Omission of postoperative radiation after breast conserving surgery: A progressive paradigm shift towards precision medicine.

Radiation therapy is a standard therapeutic option in the post-operative setting for early breast cancer patients after breast conserving surgery, providing a substantial benefit in reducing the risk of local relapse with a consequent survival gain. Nevertheless, the reduction in the burden related to treatment is becoming crucial in modern oncology for both local and systemic therapies and investigational efforts are being put forward by radiations oncologists to identify a subset of women at very low risk to be potentially omitted from post-operative irradiation after breast conservation. Clinical factors, classical pathological parameters and new predictive scores derived from gene expression and next generation sequencing techniques are being integrated in the quest toward a reliable low-risk profile for breast cancer patients.

A pilot study on the Vanderbilt head and neck symptom survey Italian version (VHNSS-IT) to test its feasibility and utility in routine clinical practice.

Purpose: Patient-reported outcome measures can be useful to assess symptoms in head and neck cancer (HNC) patients treated with radio-chemotherapy. This is a pilot study on the VHNSS-IT (the Italian version of the Vanderbilt head and neck symptom survey) performed to assess both the feasibility and utility of its administration in clinical practice.

Methods: The outcomes analyzed were feasibility to recruit patients, feasibility to complete the questionnaire, feasibility to review the questionnaire, utility perceived by clinicians, distribution of patient's answers reflecting symptom's intensity.
