Economic evaluation and budget-impact of accelerated partial breast irradiation (APBI) versus standard or hypofractionated whole breast irradiation (WBI) in postmenopausal women with early-stage breast cancer. Results from the French SHARE randomized trial.

Purpose: This economic evaluation reports the incremental cost-utility ratio and national budget impact in France of accelerated partial breast irradiation (APBI) vs standard or hypofractionated whole breast irradiation (WBI) in breast cancer patients at low risk of local recurrence.

Materials And Methods: We compared 490 women randomized to the APBI (ten fractions delivered twice daily over one week) with 488 women in the WBI arm (one fraction per day delivered five days per week over three or six weeks). We took the perspective of the French national health insurance with a three-year time horizon.

Impact of radiation therapy on fatigue at 1 year in breast cancer survivors in the prospective multicentre CANcer TOxicity cohort.

Background: Fatigue is a common and disabling symptom after breast cancer (BC) treatment, significantly impacting patients' quality of life. We aimed to assess the impact of radiation therapy (RT) modalities on fatigue one year after treatment among patients with early-stage BC.

Methods: We used CANTO-RT, a subcohort of CANcer TOxicity (CANTO; NCT01993498), a multicentric nationwide prospective cohort of stages I-III BC treated from 2012 to 2017.

A NGS-based Blood Test For the Diagnosis of Invasive HPV-associated Carcinomas with Extensive Viral Genomic Characterization.

Purpose: Use of circulating tumor DNA (ctDNA) for diagnosis is limited regarding the low number of target molecules in early-stage tumors. Human papillomavirus (HPV)-associated carcinomas represent a privileged model using circulating viral DNA (ctHPV DNA) as a tumor marker. However, the plurality of HPV genotypes represents a challenge.

Identification of Specific Tumor Markers in Vulvar Carcinoma Through Extensive Human Papillomavirus DNA Characterization Using Next Generation Sequencing Method.

Objectives: A subset of vulvar carcinomas (VC) are associated with human papillomavirus (HPV) DNA. This trait can be used to identify tumor markers for patient's follow-up. A large diversity of HPV prevalence in VC has been reported, but no data are available concerning the insertional HPV status in this tumor type.

Minichromosome maintenance complex component 6 (MCM6) expression correlates with histological grade and survival in endometrioid endometrial adenocarcinoma.

Minichromosome maintenance complex component 6 (MCM6) is involved in initiating DNA replication and is upregulated during licensed G0 phase of the cell cycle. This early expression permits its labeling of more proliferating cells than those by Ki-67. Here using a cohort of 89 endometrioid adenocarcinoma, we report findings made on the prognostic value of MCM6 based on immunohistochemical labeling index (LI) of the protein in comparison with that of Ki67 as no such information is currently available.

Expression of neurotensin receptor 1 in endometrial adenocarcinoma is correlated with histological grade and clinical outcome.

The promalignant effects of neurotensin (NTS) are sustained in many solid tumors, including hormone-dependent cancers. As the endometrium is also subjected to hormonal regulation, we evaluated the contribution of NTS to endometrial carcinogenesis. Neurotensin receptor 1 (NTSR1) expression and NTSR1 promoter methylation (HM450) were analyzed in 385 cases of endometrial carcinoma from The Cancer Genome Atlas (TCGA).

Effect of bladder distension on doses to organs at risk in Pulsed-Dose-Rate 3D image-guided adaptive brachytherapy for locally advanced cervical cancer.

Purpose: To evaluate the impact of bladder distension on doses to organs at risk in patients treated with 3D image-guided adaptive pulsed-dose-rate (PDR) brachytherapy (BT) for locally advanced cervical cancer.

Methods And Materials: Twenty-two patients who had previously been treated by external beam radiation therapy (EBRT), underwent BT treatment planning to a pelvic MRI (or a CT scan in case of contraindication) after their bladder was filled with 100 cc of physiological saline (full bladder). This was immediately followed by a CT scan after emptying of the bladder.

Impact of dosimetric and clinical parameters on clinical side effects in cervix cancer patients treated with 3D pulse-dose-rate intracavitary brachytherapy.

Background And Purpose: To assess the association between dosimetric/clinical parameters and gastrointestinal/urinary grade 2-4 side effects in cervix cancer patients treated with 3D pulse dose rate brachytherapy.

Materials And Methods: Three hundred and fifty-two patients received brachytherapy associated with external-beam radiotherapy (EBRT) for 266 of them; 236 patients underwent surgery. The doses for the most exposed 2, and 0.

Impact of 3D image-based PDR brachytherapy on outcome of patients treated for cervix carcinoma in France: results of the French STIC prospective study.

Purpose: In 2005 a French multicentric non randomized prospective study was initiated to compare two groups of patients treated for cervix carcinoma according to brachytherapy (BT) method: 2D vs 3D dosimetry. The BT dosimetric planning method was chosen for each patient in each center according to the availability of the technique. This study describes the results for 705 out of 801 patients available for analysis.

Radiotherapy for solitary extramedullary plasmacytoma in the head-and-neck region: A dose greater than 45 Gy to the target volume improves the local control.

Purpose: Our aim was to determine the dose to the clinical target volume (CTV) required for solitary extramedullary plasmacytoma (EMP) in the head and neck (HN).

Methods And Materials: Seventeen patients (15 Stage I and 2 Stage II) were treated for HN EMP at our institution between 1979 and 2003. The mean International Commission on Radiation Units (ICRU) dose prescribed to the CTV was 52.

Influence of dose point and inverse optimization on interstitial cervical and oropharyngeal carcinoma brachytherapy.

Background And Purpose: Evaluation of the use of optimization methods in interstitial cervical and oropharyngeal brachytherapy; evaluation of the conformal index (COIN) and the natural dose ratio (NDR) to quantify the implant quality.

Material And Methods: CT-based dose distributions were obtained for seven implants according to the Paris system. CT-based implants were used to assess the dose point and inverse optimization methods.

Analysis of interaction between number of implant catheters and dose-volume histograms in prostate high- dose-rate brachytherapy using a computer model.

Purpose: In prostate high-dose-rate brachytherapy, to determine before implant, using the standard geometric optimization algorithm, whether there is an optimal number of catheters.

Materials And Methods: Transrectal ultrasound images of the prostate from 24 patients were transferred into the brachytherapy planning system. Urethra and prostate contours were digitized onto each axial slice of a CT scan, as well as hypothetical locations of the catheters (2/3 of the catheters along the prostate contour, 1/3 around the urethra).

Breast-conserving therapy for ductal carcinoma in situ of the breast: the French Cancer Centers' experience.

Purpose: To assess the long-term outcome for women with ductal carcinoma in situ of the breast treated in current clinical practice by conservative surgery with or without definitive breast irradiation.

Methods And Materials: We analyzed 705 cases of ductal carcinoma in situ treated between 1985 and 1995 in nine French regional cancer centers; 515 underwent conservative surgery and radiotherapy (CS+RT) and 190 CS alone. The median follow-up was 7 years.
