BACKGROUND: Few studies with contradictory results have been published on the safety of pelvic radiation therapy (RT) in patients with inflammatory bowel disease (IBD). METHODS: From 1989 to 2015, a single center retrospective analysis was performed including all IBD patients who received pelvic external beam radiation therapy (EBRT) or brachytherapy (BT) for a pelvic malignancy. Treatment characteristics, IBD activity and gastrointestinal (GI) toxicity were examined...

PURPOSE: The phase III European Organization for Research and Treatment of Cancer 55874 study has shown that external beam radiotherapy (EBRT) given as adjuvant treatment decreased locoregional recurrences from 40% to 20% in patients (pts) with localized uterine sarcomas (US). No data exist, however, on the place of brachytherapy (BT). MATERIAL AND METHODS: We conducted a single-center retrospective analysis of pts receiving adjuvant BT of the vaginal vault based on the vaginal mold technique as part of their multimodal adjuvant treatment for a high-grade US from 1985 to 2015...

PURPOSE: With the increasing use of simultaneous integrated boost in the treatment of cervical cancer, there is a need to anticipate the brachytherapy (BT) contribution at the level of the pathologic pelvic lymph nodes. This study aimed to report the dose delivered at their level during BT. METHODS AND MATERIALS: Patients with pelvic nodal involvement and treated with a combination of chemoradiation followed by image-guided adaptive pulsed-dose-rate BT were selected...

Melanoma is traditionally considered to be a radioresistant tumor. However, radiotherapy and immunotherapy latest developments might upset this radiobiological dogma. Stereotactic radiotherapy allows high dose per fraction delivery, with high dose rate. More DNA lethal damages, less sublethal damages reparation, endothelial cell apoptosis, and finally clonogenic cell dysfunction are produced, resulting in improved local control. Radiotherapy can also enhance immune responses, inducing neoantigens formation, tumor antigen presentation, and cytokines release...

OBJECTIVE: Leukocytosis and neutrophilia could be the tip of the iceberg in the inflammatory tumor microenvironment. We aimed to validate their prognostic significance in a cohort of patients treated with definitive chemoradiation for anal squamous cell carcinoma (SCC). MATERIALS & METHODS: Clinical records from all consecutive patients treated in a single institution between 2006 and 2016 with curative-intent radiotherapy were retrospectively analyzed. Leukocytosis and neutrophilia, defined as leukocyte or neutrophil count over 10,000 and 7500/mm(3), respectively, were studied in terms of overall survival (OS), progression (PFS), locoregional (LFS) and distant (DFS)-free survival...

Immune system deregulation and evasion play a key role in cancers' evolution and progression, including squamous cell carcinoma of the head and neck (SCCHN). Development of basic research proposed a whole new vision of cancer treatment, based on a strong biological rational, and targeting intrinsic deregulations. Immunotherapies provide an encouraging strategy for patients' improved outcomes. Immune-based therapies could act on cancer growth and/or development throughout many pathways. If cetuximab is for now the only monoclonal antibody approved for SCCHN management, other strategies, e...

PURPOSE OF REVIEW: Image-guided adaptive brachytherapy (IGABT) is a high-precision radiation that allows defining accurately treatment targets and optimizing their coverage whereas sparing efficiently the surrounding organs at risk. Ten years ago, in a will of harmonizing the reporting of brachytherapy, the Groupe Européen de Curiethérapie - European Society for Radiation Oncology (GEC-ESTRO) published recommendations on target definitions and dosimetric parameters. During the last years, clinical and dosimetric studies supporting their relevance led the International Commission on Radiation Units and Measurements to propose a report on prescribing and reporting...

PURPOSE: Image-guided adaptive brachytherapy is a high precision technique that allows dose escalation and adaptation to tumor response. Two monocentric studies reported continuous dose-volume response relationships, however, burdened by large confidence intervals. The aim was to refine these estimations by performing a meta-regression analysis based on published series. METHODS AND MATERIALS: Eligibility was limited to series reporting dosimetric parameters according to the Groupe Européen de Curiethérapie-European SocieTy for Radiation Oncology recommendations...

Fertility is a major part of the global care of patients treated for cancer. A new discipline known as oncofertility has emerged in some countries. Although the relationship between chemotherapy and external radiotherapy and fertility has been studied and reported, there is only scarce data available on brachytherapy. This systematic review aims to report available knowledge on the impact of brachytherapy on fertility. Specific consultations should be considered before brachytherapy to inform patients about their fertility preservation options...

Fertility preservation in young patients with cervical cancer is suitable only for patients with good prognostic factors and disease amenable to surgery without adjuvant therapy. Consequently, it is only offered to patients with early-stage disease (stage IB tumours <4 cm), negative nodes, and non-aggressive histological subtypes. To determine whether fertility preservation is suitable, the first step is pelvic-node dissection to establish nodal spread. Tumour size (≤2 cm vs >2 cm) and lymphovascular space invasion status are two main factors to determine the best fertility-sparing surgical technique...

Ionising radiation (IR) may harm cancer cells through a rare indirect out-of-field phenomenon described as the abscopal effect. Increasing evidence demonstrates that radiotherapy could be capable of generating tumour-specific immune responses. On the other hand, effects of IR also include inhibitory immune signals on the tumour microenvironment. Following these observations, and in the context of newly available immunostimulatory agents in metastatic cancers (anti-cytotoxic T lymphocyte-associated antigen 4 and programmed cell death protein-1 or -ligand 1 [PD1 or PDL-1]), there is a remarkable potential for synergistic combinations of IR with such agents that act through the reactivation of immune surveillance...

PURPOSE: Cervical cancer patients with a bulky high-risk clinical target volume (HR-CTV) get the largest benefit of dose escalation in terms of local control. However, the expected survival benefit could be lessened by a higher metastatic risk. We examined the patterns of relapse according to major prognostic factors: the HR-CTV volume and to the D90 HR-CTV. METHODS AND MATERIALS: The clinical records of patients treated with pulsed-dose-rate image-guided adaptive brachytherapy after concurrent pelvic chemoradiation were reviewed...
