RESUMEN
Head and neck cancer (HNC) patients suffer from a range of health-related quality of life (HRQoL) issues, but little is known about their long-term HRQoL. This study explored associations between treatment group and HRQoL at least 5 years' post-diagnosis in HNC survivors. In an international cross-sectional study, HNC survivors completed the European Organization for Research and Treatment of Cancer (EORTC) quality of life core questionnaire (EORTC-QLQ-C30) and its HNC module (EORTC-QLQ-H&N35). Meaningful HRQoL differences were examined between five treatment groups: (a) surgery, (b) radiotherapy, (c) chemo-radiotherapy, (d) radiotherapy ± chemotherapy and neck dissection and (e) any other surgery (meaning any tumour surgery that is not a neck dissection) and radiotherapy ± chemotherapy. Twenty-six sites in 11 countries enrolled 1105 survivors. They had a median time since diagnosis of 8 years, a mean age of 66 years and 71% were male. After adjusting for age, sex, tumour site and UICC stage, there was evidence for meaningful differences (10 points or more) in HRQoL between treatment groups in seven domains (Fatigue, Mouth Pain, Swallowing, Senses, Opening Mouth, Dry Mouth and Sticky Saliva). Survivors who had single-modality treatment had better or equal HRQoL in every domain compared to survivors with multimodal treatment, with the largest differences for Dry Mouth and Sticky Saliva. For Global Quality of Life, Physical and Social Functioning, Constipation, Dyspnoea and Financial Difficulties, at least some treatment groups had better outcomes compared to a general population. Our data suggest that multimodal treatment is associated with worse HRQoL in the long-term compared to single modality.

BACKGROUND: Moderate hypofractionated radiotherapy is a treatment option for the cure of localized prostate cancer (PCa) patients based on the results of randomized prospective trials, but there is a clinical concern about the relatively short length of follow-up, and real-world results on outcome and toxicity based on cutting-edge techniques are lacking. The objective of this study is to present the long-term results of a large multicentric series. MATERIALS AND METHODS: We retrospectively evaluated 1325 PCa patients treated with daily volumetric image-guided hypofractionated radiotherapy between 2007 and 2020 in 16 Centers. For survival endpoints, we used Kaplan-Meier survival curves and fitted univariate and multivariable Cox's proportional hazards regression models to study the association between the clinical variables and each survival type. RESULTS: At the end of the follow-up, 11 patients died from PCa. The 15-year values of cancer-specific survival (CSS) and biochemical relapse-free survival (b-RFS) were 98.5% (95%CI 97.3-99.6%) and 85.5% (95%CI 81.9-89.4%), respectively. The multivariate analysis showed that baseline PSA, Gleason score, and the use of androgen deprivation therapy were significant variables for all the outcomes. Acute gastrointestinal (GI) and genitourinary (GU) toxicities of grade ≥ 2 were 7.0% and 16.98%, respectively. The 15-year late grade ≥ 2 GI and GU toxicities were 5% (95%CI 4-6%) and 6% (95%CI 4-8%), respectively. CONCLUSION: Real-world long-term results of this multicentric study on cutting-edge techniques for the cure of localized PCa demonstrated an excellent biochemical-free survival rate of 85.5% at 15 years, and very low rates of ≥ G3 late GU and GI toxicity (1.6% and 0.9% respectively), strengthening the results of the available published trials.

Background and Objectives: Cervical cancer is a leading cause of mortality among women. Chemo-radiation followed by interventional radiotherapy (IRT) is the standard of care for stage IB-IVA FIGO. Several studies have shown that image-guided adaptive IRT resulted in excellent local and pelvic control, but it is associated with vaginal toxicity and intercourse problems. The purpose of this review is to evaluate the dysfunctions of the sexual sphere in patients with cervical cancer undergoing different cervix cancer treatments. Materials and Methods: We performed a comprehensive literature search using Pub med, Scopus and Cochrane to identify all the full articles evaluating the dysfunctions of the sexual sphere. ClinicalTrials.gov was searched for ongoing or recently completed trials, and PROSPERO was searched for ongoing or recently completed systematic reviews. Results: One thousand three hundred fifty-six women included in five studies published from 2016 to 2022 were analyzed. The median age was 50 years (range 46-56 years). The median follow-up was 12 months (range 0-60). Cervical cancer diagnosis and treatment (radiotherapy, chemotherapy and surgery) negatively affected sexual intercourse. Sexual symptoms such as fibrosis, strictures, decreased elasticity and depth and mucosal atrophy promote sexual dysfunction by causing frigidity, lack of lubrication, arousal, orgasm and libido and dyspareunia. Conclusions: Physical, physiological and social factors all contribute to the modification of the sexual sphere. Cervical cancer survivors who were irradiated have lower sexual and vaginal function than the normal population. Although there are cures for reducing discomfort, effective communication about sexual dysfunctions following treatment is essential.

BACKGROUND AND PURPOSE: The potential for unintended and adverse radiation exposure in radiotherapy (RT) is real and should be studied because RT is a highly complex, multistep process, which requires input from numerous individuals from different areas and steps of the RT workflow. The 'Incident' (I) is an event the consequence of which is not negligible from the point of view of protection or safety. A 'near miss' (NM) is defined as an event that is highly likely to happen but did not occur. The purpose of this work is to show that through systematic reporting and analysis of these adverse events, their occurrence can be reduced. MATERIALS AND METHODS: Staff were trained to report every type of unintended and adverse radiation exposure and to provide a full description of it. RESULTS: By 2018, 110 worksheets had been collected, with an average of 6.1 adverse events per year (with 780 patients treated per year, meaning an average incident rate of 0.78%). In 2001-2009, 37 events were registered (13 I and 24 NM), the majority of them were in the decision phase (12/37), while in 2010-2013, there were 42 (1 I and 41 NM) in both the dose-calculation and transfer phase (19/42). In 2014-2018, 31 events (1 I and 30 NM) were equally distributed across the phases of the RT process. In 9/15 cases of I, some checkpoint was introduced. CONCLUSION: The complexity of the RT workflow is prone to errors, and this must be taken into account by encouraging a safety culture. The aim of this paper is to present the collected incidents and near misses and to show how organization and practice were modified by the acquired knowledge.

BACKGROUND AND PURPOSE: Breast cancer patients exposed to doses of radiation after radiotherapy could develop toxicity to lung. Lung ultrasound (LUS) is able to detect interstitial lung disease by the evaluation of B-lines. The aim of our study was to assess the number of B-lines to diagnose lung involvement after chest radiotherapy. MATERIALS AND METHODS: We measured LUS B-lines in the treated and contralateral lung of 20 breast cancer patients, 1-3 months after the end of radiotherapy and 1 year after previous LUS. The sum of the B-lines number in the 72 sites on anterior and posterior chest yielded a global B-lines score. RESULTS: B-lines were more numerous in treated (median: 21; 1st-3rd quartiles: 11-31) versus untreated hemithorax (median: 3; 1st-3rd quartiles: 1-5) in both examination at T1-3 months (Kolmogorov-Smirnov test P < 0.001) and T1 year (median: 21; 1st-3rd quartiles: 12-28 vs. median: 4; 1st-3rd quartiles: 1-10; Kolmogorov-Smirnov test P < 0.01). Within the treated hemithorax, B-lines were more frequent in the anterior than in the posterior chest in both examination at T1-3 months (Kolmogorov-Smirnov test: P < 0.0001) and T1 year (Kolmogorov-Smirnov test: P < 0.01). Abnormal scores (B-lines>5) were present in 17/20 treated versus 7/20 untreated hemithoraxes (85.0 vs. 35.0%, P < 0.01) in the first LUS and likewise in 16/17 treated versus 7/17 in untreated hemithorax (94.1% vs. 41.2%, P < 0.01) after 1-year follow-up. CONCLUSION: Among women receiving radiotherapy after breast cancer, B-lines are present predominantly in the irradiated lung. These data suggest that B-lines by LUS could provide, at a subclinical stage, a radiation-free biomarker of radiotherapy-induced lung damage.

RESUMEN
INTRODUCTION: To retrospectively report long term outcomes following postoperative hypofractionated radiotherapy (RT) for prostate cancer, emphasizing treatment related toxicity. MATERIAL AND METHODS: Patients for whom adjuvant or salvage RT was indicated after prostatectomy were treated with a course of moderate hypofractionation consisting in the delivery of 62.5 Gy in 25 fractions (2.5 Gy per fraction) on the prostate bed in 5 consecutive weeks (EQD21.5 = 70 Gy) by means of 3D-CRT in most of them. Androgen deprivation therapy (ADT) was allowed at physician's discretion. Patients were evaluated for urinary and rectal complications according to the Common Terminology Criteria for Adverse Events v4 (CTCAE v.4). Overall survival (OS), biochemical recurrence free survival (bRFS), and metastasis-free survival (MFS) were estimated using the Kaplan-Meier method. RESULTS: One hundred and ten patients with a median age of 67 years (range 51-78) were enrolled. The majority of them (82%) had adverse pathologic features only, while 31 (28%) had early biochemical relapse. Median PSA level before RT was 0.12 ng/mL (range 0-9 ng/mL). Median time from surgery was 4 months (range 1-136 months). Twenty-eight patients (25.4%) also received ADT. At a median follow up of 103 months (range 19-138 months), late Grade 3 and Grade 4 rectal toxicity were 0.9% (1 case of hematochezia) and 0.9% (1 case of fistula), respectively, while late Grade 3 GU side effects (urethral stenosis) occurred in 9 cases (8%). No late Grade 4 events were observed, respectively. Ten-year OS, b-RFS and MFS were 77.3% (95%CI: 82.1%-72.5%), 53.3% (95%CI: 59.9%-47.6%), and 76.7% (95%CI: 81.2%-72.2%), respectively. CONCLUSION: Our study provides long term data that a shortened course of postoperative RT is as safe and effective as a long course of conventionally fractionated RT and would improve patients' convenience and significantly reduce RT department workloads.

Objectives: To evaluate the role of 18F-fluorocholine (18F-FCH) positron emission tomography/computed tomography (PET/CT) in prostate cancer (PC) patients with biochemical recurrence who were submitted to different curative treatments. Methods: Seventy-five patients with PC who underwent 18F-FCH PET/CT for biochemical recurrence were retrospectively analyzed to distinguish patients who were submitted only to prostatectomy (PR group), only to radiotherapy (RT) on prostate with curative intent (RT group), and to both (PR + RT group). Correlations between 18F-FCH PET/CT and outcome and between prostate-specific antigen (PSA) values and sites and the number of metastases were analyzed. The performance of 18F-FCH PET/CT in relation to the PSA value and of maximum standardized uptake value (SUVmax) value in relation to patient outcome were assessed by receiver operating characteristic (ROC) curves. Results: 18F-FCH PET/CT relapses mostly involved lymph nodes, bones, and prostate bed. K-cohen test showed moderate agreement with the outcome in the whole population and in the PR group, whereas in the RT group it was perfect and in PR + RT fair. A statistically significant difference in PSA values was observed in the presence of lymph node metastases and with multiple metastases. ROC curves showed PSA cut-off values of 1.96 ng/dL, 1.95, 1.81, and 2.96, respectively, in the whole population, PR, RT and PR + RT group. SUVmax cut-off values of 3.75, 3.45, and 4.7 were described in the whole population, PR group, and PR + RT group. Conclusion: The study confirms that 18F-FCH PET/CT is still valid in PC patients with suspected biochemical recurrence. Therefore, we can affirm that it still makes sense to perform it both with high PSA values and with lower values when prostate-specific membrane antigen tracers are not available.

The long-term problems of head and neck cancer survivors (HNCS) are not well known. In a cross-sectional international study aimed at exploring the long-term quality of life in this population, 1114 HNCS were asked to state their two most serious long-term effects. A clinician recorded the responses during face-to-face appointments. A list of 15 example problems was provided, but a free text field was also available. A total of 1033 survivors responded to the question. The most frequent problems were 'dry mouth' (DM) (n = 476; 46%), 'difficulty swallowing/eating' (DSE) (n = 408; 40%), 'hoarseness/difficulty speaking' (HDS) (n = 169; 16%), and 'pain in the head and neck' (PHN) (n = 142; 14%). A total of 5% reported no problems. Logistic regression adjusted for age, gender, treatment, and tumor stage and site showed increased odds of reporting DM and DSE for chemo-radiotherapy (CRT) alone compared to surgery alone (odds ratio (OR): 4.7, 95% confidence interval (CI): 2.5-9.0; OR: 2.1, CI: 1.1-3.9), but decreased odds for HDS and PHN (OR: 0.3, CI: 0.1-0.6; OR: 0.2, CI: 0.1-0.5). Survivors with UICC stage IV at diagnosis compared to stage I had increased odds of reporting HDS (OR: 1.9, CI: 1.2-3.0). Laryngeal cancer survivors had reduced odds compared to oropharynx cancer survivors of reporting DM (OR: 0.4, CI: 0.3-0.6) but increased odds of HDS (OR: 7.2, CI: 4.3-12.3). This study provides evidence of the serious long-term problems among HNCS.
RESUMEN
OBJECTIVES: We aimed to analyze the impact of a 3-week schedule of HypoFractionated (HF) radiotherapy (RT) after axillary dissection and breast surgery, in terms of safety and efficacy in patients with locally advanced breast cancer (BC). METHODS: Eligible patients were females with Stage IIA - IIIC BC who underwent axillary dissection and breast surgery, either quadrantectomy or mastectomy. HF RT was delivered in 15 or 16 fractions for a total dose of 40.05 Gy or 42.56 Gy, respectively, to the clavicular nodal region along with the whole breast (HF WBRT) or the chest wall (HF PMRT), according to the type of surgery. Locoregional recurrence (LRR), distant metastases-free survival (DMFS), overall survival (OS) and acute and late treatment-related toxicities were estimated. RESULTS: 57 patients with a median age of 60 years (32-85) were retrospectively analyzed. 34 (60%) of patients underwent breast conservative surgery in the form of quadrantectomy and 23 (40%) were offered radical mastectomy. All patients underwent hypofractionated regional nodal irradiation (HF RNI). 34 (60%) of them underwent HF WBRT, while 23 (40%) received HF PMRT.At a median follow-up of 80 months (30-113), the 7-year LRR-free survival was 93% (95% CI, 74%-95%). The same features for DMFS and OS were 76% (95% CI, 52%-78%) and 67% (95% CI, 50%-80%), respectively. Only one (2%) patient experienced G3 acute skin toxicity. No grade ≥2 late toxicity was observed. CONCLUSION: Our study shows that HF RNI with HF RT to the whole breast or the chest wall after breast surgery is safe and effective in patients with locally advanced BC. Longer follow-up is needed to strengthen further analyses on late toxicity and clinical outcomes. ADVANCES IN KNOWLEDGE: This paper adds to the evidence that post-operative RNI with WBRT or PMRT can be safely and effectively delivered with 3-week HF regimen. Locally advanced BC patients can be offered HF RT to the regional nodes and the breast or the chest wall regardless the type of surgery.

OBJECTIVES: This review systematically summarizes the evidence on the economic impact of magnetic resonance image-guided RT (MRIgRT). METHODS: We systematically searched INAHTA, MEDLINE, and Scopus up to March 2022 to retrieve health economic studies. Relevant data were extracted on study type, model inputs, modeling methods and economic results. RESULTS: Five studies were included. Two studies performed a full economic assessment to compare the cost-effectiveness of MRIgRT with other forms of image-guided radiation therapy. One study performed a cost minimization analysis and two studies performed an activity-based costing, all comparing MRIgRT with X-ray computed tomography image-guided radiation therapy (CTIgRT). Prostate cancer was the target condition in four studies and hepatocellular carcinoma in one. Considering the studies with a full economic assessment, MR-guided stereotactic body radiation therapy was found to be cost effective with respect to CTIgRT or conventional or moderate hypofractionated RT, even with a low reduction in toxicity. Conversely, a greater reduction in toxicity is required to compete with extreme hypofractionated RT without MR guidance. CONCLUSIONS: This review highlights the great potential of MRIgRT but also the need for further evidence, especially for late toxicity, whose reduction is expected to be the real added value of this technology.

PURPOSE: To analyze survival and complications in high dose 3D conformal radiotherapy (3DCRT) patients treated with curative and post-operative intent and compare radical surgery + radiotherapy (RT) patients vs. RT only patients. MATERIAL AND METHOD: 103 patients were treated curatively (RAD), 94 postoperatively (POST-OP). The mean age was higher in RAD group (72.6 years, range 56.4-85.1) than in POST-OP group (65.4 years, 43.9-77) (p < 0.0001). According to NCCN prognostic classification 13 (12%) patients was low risk, 48 (47%) intermediate risk and 42 (41%) high risk in RAD group. In POST-OP group 13 (14%) patients were low risk, 37 (40%) intermediate risk and 44 (46%) high risk. Hormone Therapy (HT) was administered in 98 patients (95%) in RAD and in 45 patients (47.8%) in POST-OP. Patients were treated with a three-dimensional conformal radiotherapy (3D-CRT). In RAD 15 (15%) were alive with disease (AWD), 5 (5%) dead of disease (DOD) and 10 (10%) dead of other cause (DOC); in POST-OP 14 (14.8%) were AWD, 2 (2%) DOD and 3 (3%) DOC. The prescription dose was 80 Gy in 2-Gy fractions in the RAD group, and 70 Gy in 2-Gy fractions in the POST-OP, respectively. RESULTS: No biochemical or clinical relapse was found in low risk patients in RAD group and 1 relapse in POST-OP group. The largest number of relapses occurred and in intermediate-high risk in RAD (39%) and POST-OP group (33%). In the cause-specific survival analysis no significant differences were found in high risk group between RAD and POST-OP (p = 0.9). In the biochemical relapse-free survival (bRFS) at 5 years analysis no significant differences were found in the high risk group between RAD and POST-OP (p = 0.1020). CONCLUSION: RT in RAD low- risk is very effectiva. RAD and POST-OP RT were well tolerated with a very low toxicity. The cause-specific survival at 5 years was 95% and 97% for the two groups of treatment, RAD and POST-OP respectively (Log-rank test p = 0.2908).

BACKGROUND: The impetuous entrance of the COVID-19 pandemic in Italy in March 2020, after the onset and diffusion in China, found the health system widely unfit to face the large amount of infected patients. The matter of this investigation was to evaluate how pandemic fear and guidelines for limiting the diffusion of SARS-CoV-2 virus could have impacted the regular supply of radiotherapy (RT) and the outcome of the treatments. MATERIALS AND METHODS: From March 9, 2020, to May 29, 2020, a register has been established to record patients that cancelled or postponed the RT appointment. The reasons were as follows: (1) patients whose appointments were postponed by the staff according to national guidelines; (2) patients who asked themselves to postpone the appointment; (3) patients who interrupted the treatment for causes directly or indirectly related to the pandemic; (4) patients who cancelled their care path. RESULTS: A total number of 277 patients started regular RT, and 384 respected their computed tomography (CT) simulation appointment, but 60 of them had alteration of their therapeutic pathway. Among these, 18 cancelled their appointment. 42 patients asked to postpone their procedure. Twenty-seven out of 42 adduced directly or indirectly SARS-CoV-2 infection-related reasons. CONCLUSIONS: The COVID-19 pandemic affected the regular RT delivery to oncologic patients, owing to the delay or cancellation of procedures with the likely effect to observe worsening of local disease control and reduced survival rates in the future.
RESUMEN
PURPOSE: to report on the use of an internal system for incident reporting. PATIENTS AND METHODS: from October 2001 until June 2009, data on incidents were collected in the radiotherapy department (RT) by means of an incident reporting worksheet. The risk analysis was based on the US Navy method of mishap cause investigation, the Human Factors Analysis and Classification System (HFACS). RESULTS: 37 incidents over 5,635 treatments were collected. Of the incidents, 20 involved deviation of the dose to the patient; only 6 showed clinical evidence of overdosage, while 2 of them showed permanent evidence of overdosage. There were 24 incidents that were classified as near misses (NM). Incorrect data input and use of an incorrect treatment field were the most common causes of the registered incidents. Reactive risk analysis showed how skill-based errors were associated with attention failure at the unsafe act level. Dose prescription and dose calculation are the most critical phases of the entire process. Most of the errors were discovered in set-up/treatment and during treatment visit/follow-up phases. The highest number of correction procedures was necessary in the phases of dose prescription and dose calculation. CONCLUSION: collecting and analyzing internal incidents improves the operative procedures used in the department.

BACKGROUND: Several studies have shown that common carotid intima-media thickness (IMT) is increased after radiotherapy (RT) to the head and neck. However, further studies are needed to define the exact mechanism of radiation-induced injury in large vessels, investigate the relationship between radiation dose and large vessel injury and evaluate the rate of progress of atherosclerosis in irradiated vessels. OBJECTIVES: To investigate whether external irradiation to the carotid area has any effect on IMT of the common carotid artery in a group of patients who received RT vs control group matched for age, gender and race. METHODS: We studied 19 patients (10 male; 47.8 +/- 17.4 years) during a 5-month period (January 2009-July 2009); they had completed RT with a mean of 2.9 years before (range: 1 month-6 years) The mean radiation dose to the neck in the irradiated patients was 41.2 +/- 15.6 Gy (range: 25-70 Gy). Common carotid IMT was measured with echo-color Doppler. Nineteen healthy adult patients (10 male; 47.8 +/- 17.6) were recruited as a control group. RESULTS: IMT was not significantly higher in patients when compared to the control group (0.59 +/- 0.16 vs 0.56 +/- 0.16 mm, p = 0.4). There was no significant difference between the two groups in relation to the absence (p = 0.7) or presence (p = 0.6) of vascular risk factors. Although the difference did not reach statistical significance (p = 0.1), the irradiated young patients (age < or = 52 years) had IMT measurements higher (0.54 +/- 0.08 mm) than the non-irradiated young patients (0.49 +/- 0.14 mm). The mean carotid IMT increased with increasing doses of radiation to the neck (p = 0.04). CONCLUSION: This study shows that increased IMT of the common carotid artery after RT is radiation-dose-related. Therefore it is important to monitor IMT, which can be used as an imaging biomarker for early diagnosis of cerebrovascular disease in patients who have had radiotherapy for treatment of cancer of the head and neck and who are at increased risk for accelerated atherosclerosis in carotid arteries.

RESUMEN
BACKGROUND: Left-sided breast cancer patients treated with radiotherapy (RT) are at risk for late radiation-induced cardiovascular complications. AIM: The aim of this study was to investigate the BNP plasma levels in long-term breast cancer survivors who received only RT as well to assess whether cardiac dose was associated with BNP values. METHODS: Plasma samples for BNP measurement were repeated in 29 patients (63 ± 11 years) who were alive at 5 years after radiotherapy, free of heart disease and available to provide new blood sample. All patients had BNP measurements at baseline. The ΔBNP was measured to analyze the role of marker variations. No patients received chemotherapy. RESULTS: The mean cardiac and ventricle dose were 2.1 ± 1.0 (range 0.02-4.5) Gy and 3.0 ± 1.7 (range 0.02-7.6), respectively. Median value of BNP was 47 pg/mL (interquartile ranges, 26-58.2 pg/mL) at baseline, and 34 pg/mL (interquartile ranges, 17.5-54 pg/mL) at 5 years after radiotherapy. There was no significantly different between two measurements (p = ns). Fifteen (52%) reported an improvement in BNP levels, 1 (3%) no changes and 13 (45%) reported a worsening. There was no correlation between ΔBNP and age (p = ns). When patients were stratified according to the median value of dose-volume data, ΔBNP was significantly higher in patients with increased cardiac Dmean (p = .02) and left ventricle Dmean (p = .009). CONCLUSION: At 5 years after radiotherapy, median plasma BNP levels remained within the normal range, but the delta-BNP levels are directly related to the heart and ventricular dose received.

AIM: To retrospectively investigate outcomes, and acute and late complications following postoperative hypofractionated 3D conformal radiotherapy. PATIENTS AND METHODS: Sixty-nine consecutive patients underwent radical prostatectomy. Radiotherapy was delivered to the prostatic fossa by means of a7-fieldLINACwith 6-15 MV to a total dose of 62.5 Gy in 25 fractions (2.5 Gy per fraction) in five consecutive weeks. RESULTS: Median follow-up was 54.7 months (range=38-76 months). Five-year overall survival, metastasis-free survival and biochemical relapse-free survival were 91.1%, 84.6% and 66.7%, respectively. Grade 2 or more genitourinary and gastrointestinal acute toxicity was reported in 12% and 5% of patients, respectively. Urinary incontinence grade 2 or more was recorded in 19%. CONCLUSION: Postoperative radiotherapy either in the adjuvant or salvage setting resulted in acceptable rates of acute and late toxicity with good tumor control while reducing overall treatment time. Confirmatory results from an ongoing prospective trial are awaited.

BACKGROUND AND PURPOSE: Radiation therapy (RT) for breast cancer after conservative surgery can be life-saving but remains associated with significant late side effects, including lung fibrosis, detected by chest CT. Aim of this study was to assess whether lung ultrasound (LUS) may detect late lung fibrosis through the biomarker of B-lines. MATERIALS AND METHODS: We evaluated 30 women (median age 67 years, range 46-80 years) about 3-8 years after RT (follow up 38-101 months, median 58 months) for left (n = 12) or right (n = 18) breast cancer (stage 1, n = 24; stage 2, n = 6), treated with total dose 40.5 - 50.00 Gy with/without boost dose). In all, both treated and contralateral hemithorax were evaluated. LUS was performed and B-lines evaluated with a 28-region antero-lateral scan, from second to fifth intercostal spaces, along the mid-axillary, anterior axillary, mid-clavicular, and parasternal lines. In each space, the B-lines were counted from 0 = black lung to 10 = white lung. The sum of B-lines in all spaces generated the B-line score of each hemithorax. RESULTS: Median B-line score was higher in the irradiated site than in the contralateral control hemithorax (9, 1st-3rd quartiles: 2-23 vs 3, 1st-3rd quartiles: 1-4; P < 0.05). In the treated hemithorax, higher mean lung doses ( > median value of 2.7 Gy) were associated with more B-lines when compared to lower doses (< 2.7 Gy): 9 vs 5, p <0.001. CONCLUSION: RT in female breast cancer survivors is associated with increase in B-lines in the targeted hemithorax, likely due to lung fibrosis, and related to the lung mean dose. LUS can provide a simple "echo-marker" of lung fibrosis.
