To analyse the displacement of surgical clips in prone (Pr) position and assess the consequences on target volumes and integral dose of partial breast irradiation (PBI). 30 post-lumpectomy breast cancer patients underwent CT imaging in supine (Su) and Pr. Clip displacements were measured by the distances from the clips to a common fix bony reference point. On each dataset, the tumour bed (TB = clips ± seroma), clinical target volume (CTV = TB + 1.5 cm) and planning target volumes (PTV = CTV + 1 cm) for PBI were determined and the volume pairs were compared. Furthermore estimation of integral dose ratio (IDR) within the breast from tangential treatment was performed as the ratio of the irradiated breast volume and the volume encompassing all clips. Clips close to the chest wall (CW) in Su showed significantly less displacement in Pr. The mean volumes of seroma, CTV and PTV were significantly higher in Pr than in Su. The PTV volume difference (Pr-Su) was significantly higher in patients with presence of seroma, deep clips and TB location in the superior-internal-quadrant (SIQ) and at the junction of superior quadrants (jSQ). In a multivariate analysis two factors remained significant: seroma and TB localization in SIQ-jSQ. The IDR was significantly larger in Su than in Pr (7.6 vs. 4.1 p < 0.01). Clip displacements varied considerably with respect to their relative position to the CW. In selected patients Pr position potentially leads to a significant increase in target volumes of PBI. Tangential beam arrangement for PBI should be avoided, not only in Su but in Pr as well in case of clip-based target volume definition. [less ▲]

Purpose:Feasibility evaluation of the Sagittilt© prone breast board system (Orfit Industries, Wijnegem, Belgium) for radiotherapy focusing on patient and staff satisfaction, treatment time, treatment reproducibility with the assessment of residual-intrafractional errors. Material and methods: Thirty-six patients underwent whole-breast irradiation in prone position. Seventeen received a sequential boost (breast: 42.56 Gy in 16 fractions, boost: 10 Gy in five fractions), while 19 patients received a concomitant boost protocol (breast/boost: 45.57/55.86 Gy in 21 fractions). Treatment verification included a daily online cone-beam CT (CBCT). In order to assess the residual and residual-intrafractional errors post-treatment CBCTs were performed systematically at the first five treatment sessions. Treatment time, patient comfort, staff satisfaction were also evaluated. Results: The pretreatment CBCT resulted in a population systematic error of 4.5/3.9/3.3 mm in lateral/longitudinal/vertical directions, while the random error was 5.4/3.8/2.8 mm. Without correction these would correspond to a clinical to planning target volume margin of 15.0/12.3/10.3 mm. The population systematic and random residual-intrafractional errors were 1.5/0.9/1.7 mm and 1.7/1.9/1.6 mm. Patient and staffs’ satisfaction were considered good and average. The mean treatment session time was 21 minutes (range: 13–40 min). Conclusion: The Sagittilt© system seems to be feasible for breast irradiation and well-tolerated by patients, acceptable to radiographers and reasonable in terms of treatment times. Set-up accuracy was comparable with other prone systems; residual errors need further investigations. [less ▲]

Background and purpose: The aim of this study was to assess the efficacy of a 38-h communication skills training program designed for multidisciplinary radiotherapy teams. Materials and methods: Four radiotherapy teams were randomly assigned to a training program or to a waiting list. Assessments were scheduled at baseline (T1) and then after the training was completed or four months later (T2), respectively. Communication around radiotherapy delivery was assessed based on audio recordings of the first and last radiotherapy sessions in order to assess team members’ communication skills and the expression of concerns by breast cancer patients (analyzed with content analysis software LaComm). Results: 198 radiotherapy sessions were recorded. During the first radiotherapy sessions, members of the trained teams exhibited more assessment skills (p = 0.048), provided more setting information (p < 0.001), and used more social words (p = 0.019) compared to the members of the untrained teams. During the last radiotherapy session, members of the trained teams used more assessment skills (p = 0.004) and patients interacting with members of the trained teams expressed more sadness words (p = 0.023). Conclusion: Training of multidisciplinary teams has the potential to transfer skills that affect the short exchanges that take place around radiotherapy delivery. [less ▲]

During the last decade, the initial cancer cell-centered view of tumors has greatly evolved to an integrated vision of tumor biology taking into account the key contribution of the TME. Obviously, the different compartments of TME are closely related and contribute not only to tumor progression, but also to its response to treatments. Importantly, the TME evolves over time during the different steps of cancer development and is also affected by different therapeutic modalities. Although, improvements have been achieved regarding RT delivery to the primary tumor, ionizing radiation also target nontumor cells that influence tumor growth and metastatic dissemination. Different approaches have been proposed to overcome the radioresistance of cancer cells. The TME-mediated radioresistance is now the object of researches, which has been elegantly reviewed recently by Barker et al. (2015) and severalarticles pointed out the importance of treatments that modify the TME and likely radiosensitize tumor (Ansiaux et al., 2005; Crokart et al., 2005b; Frérart et al., 2008). However, the impact of anti-cancer treatments on the TME and consequently on the tumor phenotype, response to treatment and metastases, is often neglected. Here we pointed out the impact of RT on the TME. Recent findings emphasize the interest to optimize RT (i.e., dose per fraction) and timing of surgery (Leroi et al., 2015; Surace et al., 2015) in order to prevent metastatic spreading. The future challenge in RT will be to define the most appropriate combinations between RT, and other therapeutic modalities with the optimal sequence and timing of treatments. In this context, investigation of the TME-related acquired resistance will be essential and will provide important innovative data. [less ▲]

Purpose/Objective. Neoadjuvant radiotherapy (NeoRT) improves tumor local control and tumor resection in many cancers. The timing between the end of the NeoRT and surgery is mostly driven by the occurrence of side effects or the tumor downsizing. We previously demonstrated in an in vivo model that the timing of surgery and the schedule of NeoRT influenced the tumor dissemination. Here, our aim is to evaluate with functional MRI (fMRI) the impact of the radiation treatment on the tumor microenvironment and subsequently to identify non-invasive markers helping to determine the best timing to perform surgery for avoiding tumor spreading. First, we needed to demonstrate the feasibility of repetitive MRI imaging after NeoRT in mice. Material/methods. We used two models of NeoRT we previously developed in mice: MDA-MB 231 and 4T1 cells implanted in the flank of mice. When tumors reached the planned volume, they are irradiated with 2x5 Gy and then surgically removed at different time points after RT. In the mean time between the end of RT and the surgical procedure, mice were imaged in a 9,4T Agilent® MRI. Diffusion Weighted (DW) -MRI was performed every 2 days between RT and surgery. For each tumors we acquired 8 slices of 1 mm thickness and 0.5 mm gap with an “in plane voxel resolution” of 0.5 mm. For DW-MRI, we performed FSEMS (Fast Spin Echo MultiSlice) sequences, with 9 different B-values (from 40 to 1000) and B0, in the 3 main directions. We also performed IVIM (IntraVoxel Incoherent Motion) analysis, in the aim to obtain information on intravascular diffusion, related to perfusion (F: perfusion factor) and subsequently tumor vessels perfusion. Results. As preliminary results, with the MBA-MB 231 we observed a significant increase of F at day 6 after irradiation than a decrease and stabilization until surgery. No other modifications of the MRI signal, ADC, D or D* were observed. We observed similar results with 4T1 cells, F increased at day 3 than returned to initial signal. The difference in the timing of the peak of F can be related to the difference in tumor growth between MBA-MB 231 and 4T1 (four weeks vs one week). Conclusion. For the first time, we demonstrate the feasibility of repetitive fMRI imaging in mice models after NeoRT. With these models, we show a significant peak of the perfusion factor (F) at day 6 or day 3. This change occurs between the two previous time points of surgery demonstrating a difference in the metastatic spreading. Indeed, after a NeoRT of 2X5Gy we observed more metastases in the lung when MDA-MB 231 tumor bearing mice are operated 4 days after RT compared to 11 days. These preliminary results are very promising for identifying noninvasive markers for determining the best timing for surgery. [less ▲]

Neoadjuvant radiotherapy (NeoRT) improves tumor local control and tumor resection in many cancers. The timing between the end of the NeoRT and surgery is driven by the occurrence of side effects or the tumor downsizing. Some studies demonstrated that the timing of surgery and the RT schedule could influence tumor dissemination and subsequently patient overall survival. We demonstrated the impact of NeoRT on metastatic spreading in a Scid mice model. After an irradiation of 2x5gy, we show more metastasis in the lung when the mice are operated at day 4 compared to day 11. Here, our aim is to evaluate with functional MRI (fMRI) the impact of the radiation treatment on the tumor microenvironment and subsequently to identify non-invasive markers helping to determine the best timing to perform surgery for avoiding tumor spreading.

PURPOSE: Our primary objective was to determine if [18F]FPRGD2 PET/CT performed at baseline and/or after chemoradiotherapy (CRT) could predict tumour regression grade (TRG) in locally advanced rectal cancer (LARC). Secondary objectives were to compare baseline [18F]FPRGD2 and [18F]FDG uptake, to evaluate the correlation between posttreatment [18F]FPRGD2 uptake and tumour microvessel density (MVD) and to determine if [18F]FPRGD2 and FDG PET/CT could predict disease-free survival. METHODS: Baseline [18F]FPRGD2 and FDG PET/CT were performed in 32 consecutive patients (23 men, 9 women; mean age 63 +/- 8 years) with LARC before starting any therapy. A posttreatment [18F]FPRGD2 PET/CT scan was performed in 24 patients after the end of CRT (median interval 7 weeks, range 3 - 15 weeks) and before surgery (median interval 4 days, range 1 - 15 days). RESULTS: All LARC showed uptake of both [18F]FPRGD2 (SUVmax 5.4 +/- 1.5, range 2.7 - 9) and FDG (SUVmax 16.5 +/- 8, range 7.1 - 36.5). There was a moderate positive correlation between [18F]FPRGD2 and FDG SUVmax (Pearson's r = 0.49, p = 0.0026). There was a moderate negative correlation between baseline [18F]FPRGD2 SUVmax and the TRG (Spearman's r = -0.37, p = 0.037), and a [18F]FPRGD2 SUVmax of >5.6 identified all patients with a complete response (TRG 0; AUC 0.84, 95 % CI 0.68 - 1, p = 0.029). In the 24 patients who underwent a posttreatment [18F]FPRGD2 PET/CT scan the response index, calculated as [(SUVmax1 - SUVmax2)/SUVmax1] x 100 %, was not associated with TRG. Post-treatment [18F]FPRGD2 uptake was not correlated with tumour MVD. Neither [18F]FPRGD2 nor FDG uptake predicted disease-free survival. CONCLUSION: Baseline [18F]FPRGD2 uptake was correlated with the pathological response in patients with LARC treated with CRT. However, the specificity was too low to consider its clinical routine use. [less ▲]

INTRODUCTION: With 18F-FDG PET/CT, tumor uptake intensity and heterogeneity have been associated with outcome in several cancers. This study aimed at investigating whether 18F-FDG uptake intensity, volume or heterogeneity could predict the outcome in patients with non-small cell lung cancers (NSCLC) treated by stereotactic body radiation therapy (SBRT). METHODS: Sixty-three patients with NSCLC treated by SBRT underwent a 18F-FDG PET/CT before treatment. Maximum and mean standard uptake value (SUVmax and SUVmean), metabolic tumoral volume (MTV), total lesion glycolysis (TLG), as well as 13 global, local and regional textural features were analysed. The predictive value of these parameters, along with clinical features, was assessed using univariate and multivariate analysis for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). Cutoff values were obtained using logistic regression analysis, and survivals were compared using Kaplan-Meier analysis. RESULTS: The median follow-up period was 27.1 months for the entire cohort and 32.1 months for the surviving patients. At the end of the study, 25 patients had local and/or distant recurrence including 12 who died because of the cancer progression. None of the clinical variables was predictive of the outcome, except age, which was associated with DFS (HR 1.1, P = 0.002). None of the 18F-FDG PET/CT or clinical parameters, except gender, were associated with OS. The univariate analysis showed that only dissimilarity (D) was associated with DSS (HR = 0.822, P = 0.037), and that several metabolic measurements were associated with DFS. In multivariate analysis, only dissimilarity was significantly associated with DSS (HR = 0.822, P = 0.037) and with DFS (HR = 0.834, P < 0.01). CONCLUSION: The textural feature dissimilarity measured on the baseline 18F-FDG PET/CT appears to be a strong independent predictor of the outcome in patients with NSCLC treated by SBRT. This may help selecting patients who may benefit from closer monitoring and therapeutic optimization. [less ▲]

Background : Breast cancer is the most frequent cancer in women, affecting 8 women out of 100. With early detection and improved treatments, the number of deaths linked to this disease has declined. However, the disease and its treatments are at the origin of many undesirable side effects such as fatigue, anxiety, weight gain and sleep disorders. The objective of this study is to determine the psychological benefits of a multidisciplinary rehabilitation program among women treated for breast cancer (on average six months after the end of the adjuvant radiotherapy or chimiotherapy). Material and methods : 122 patients were included into a control group (n = 61) and a treated group (n = 61). All participants were submitted to evaluations before the beginning of the trial and after three months. These evaluations included different questionnaires exploring the quality of life, anxiety, depression and various functions and other symptoms related to cancer (EORTC QLQ-C30, EQ-5D, STAI, HADS) and functional assessments. The control group has received no intervention unlike the treated group that received a three-month rehabilitation including supervised physical training (90 min) with three times a week and various psycho-educational sessions (120 min) once a week. Results : After three months, the health status (quality of life) (p < 0,0001), the functional role (p = 0,031), emotional state (p < 0,0001) and physical (p = 0,0045), cognitive (p = 0,0027) and social functions (p = 0,0018) improve significantly in the treated group. This observation also applies to symptoms of fatigue (p < 0,0001), insomnia (p < 0,0001), pain (p = 0,002), dyspnea (p = 0,009), loss of appetite (p = 0,04), anxiety (p < 0,0001) and depression (p < 0,0001) as well as physical parameters obtained through functional assessments. In the control group, these improvements do not appear. Conclusions : This study shows the feasibility and psychological benefits of such a multidisciplinary oncological rehabilitation program in women after their treatments for breast cancer. Additional studies are needed to know the optimal time of beginning (during treatments or after them) and the optimal management time for this support. [less ▲]

Background : Breast cancer is the most frequent cancer in women, affecting 8 women out of 100. With early detection and improved treatments, the number of deaths linked to this disease has declined. However, the disease and its treatments are at the origin of many undesirable side effects such as fatigue, anxiety, weight gain and decreased physical fitness. The objective of this study is to determine the physical benefits of a multidisciplinary rehabilitation program among women treated for breast cancer (on average six months after the end of the adjuvant radiotherapy or chimiotherapy). Material and methods : 122 patients were included into a control group (n = 61) and a treated group (n = 61). All participants were submitted to evaluations before the beginning of the trial and after three months. These evaluations included functional assessments (a maximal incremental exercise protocol on a cycle ergometer, flexibility by Sit and Reach Test and walking distance by Six-Minute Walk Test), anthropometric and body composition measurements (Body Mass Index and body fat percentage) and different questionnaires on quality of life, anxiety and other symptoms related to cancer. The control group has received no intervention unlike the treated group that received a three-month rehabilitation including supervised physical training (90 min) with three times a week and various psycho-educational sessions (120 min) once a week. Results : After three months, maximal oxygen consumption (p < 0,0001), maximal aerobic power (p < 0,0001), peak of ventilation (p < 0,0001) and time to exhaustion (p = 0,0055) during the maximal incremental exercise protocol improve significantly in the treated group. This observation also applies to flexibility (p < 0,0001), walking distance in six minutes (p < 0,0001) and different physical and psychological parameters obtained through questionnaires. In the control group, these improvements do not appear and a significant increase in body mass index (p = 0,032) and body fat percentage (p = 0,034) is observed while these data remain constant in the treated group. Conclusions : This study shows the feasibility and physical benefits of such a multidisciplinary oncological rehabilitation program in women after their treatments for breast cancer. Additional studies are needed to know the optimal time of beginning (during treatments or after them) and the optimal management time for this support. [less ▲]
