RESUMO

There are a large number of gynaecological cancers with rare histologies, for which the available data are limited and usually retrospective. Because of their rarity and poor prognosis, the management of these cancers must be centralized in expert centres, for both histological diagnosis and treatment. With the exception of sarcomas, most endometrial or cervical cancers with rare histologies respond to the same radiation treatment modalities than cancers with more common histologies, although there are some specificities regarding treatments such as neuroendocrine carcinomas (chemotherapy with platinum and etoposide, major role of surgery). For localized or locally advanced ovarian cancer, external beam radiotherapy has a role in the management of hypercalcaemic small cell carcinoma of the ovary. This article summarizes the current role of external beam radiotherapy and brachytherapy in the management of cancers of the uterine cervix, uterine corpus and ovaries, with rare or very rare histologies, and with localized or locally advanced stages.

RESUMO

In Europe, endometrial cancer is the fourth most common cancer among women. The majority of patients are diagnosed at a localized stage. For these patients, the standard of care is based on an hysterectomy with salpingo oophorectomy±lymph node staging. Through the assessment of histopathologic features, risk groups are determined: low, intermediate, high-intermediate, and high risk. Adjuvant strategies are guided by these risk groups. While the prognosis of low-risk and high-risk is well known, that of intermediate and high-intermediate risk is more heterogeneous, and the therapeutic index of adjuvant treatments is more questionable. Several trials (PORTEC [Post Operative Radiation Therapy in Endometrial Carcinoma] I, GOG [Gynecologic Oncology Group] 99, ASTEC [A Study in the Treatment of Endometrial Cancer] EN.5, PORTEC II, Sorbe et al trial) have assessed observation, vaginal cuff brachytherapy and/or pelvic external beam radiotherapy in this population. Vaginal cuff brachytherapy reduces the local recurrence rate, and pelvic external beam radiotherapy the pelvic recurrence rate. However, no benefit in terms of overall survival or occurrence of distant metastases is highlighted. Compared to observation, brachytherapy and above all external beam radiotherapy are associated with an increased morbidity, and with a decreased quality of life. In order to improve the therapeutic ratio and to optimize medico-economic decisions, therapeutic de-escalation strategies, based on the molecular profiles, are emerging in clinical trials, and in the recommendations for the management of intermediate and high-intermediate risk endometrial cancers. The four main molecular profiles highlighted by the genomic analyzes of The Cancer Genome Atlas (TCGA) - POLE (polymerase epsilon) mutation, non-specific molecular profile, MMR (MisMatch repair) deficiency, and p53 mutation - but also the quantification of lymphovascular space invasion (absent, focal or substantial), and the assessment of L1CAM (L1 cell adhesion molecule) overexpression represent growing concerns. Thus, the use of molecular-integrated risk profile to determine the best adjuvant treatment represent a major way to personalize adjuvant treatment of endometrial cancers, with therapeutic de-escalation opportunity for around half of the high-intermediate risks. However, in the absence of prospective data, inclusion in clinical trials assessing molecular profile-based treatment remains the best therapeutic opportunity.

RESUMO

BACKGROUND: Several techniques can be proposed as fertility sparing surgery in young patients treated for cervical cancer but uncertaincies remain concerning their outcomes. Analysis of oncological issues is then the first aim of this review in order to evaluate the best strategy. RESULTS: Data were identified from searches of MEDLINE, Current Contents, PubMed and from references in relevant articles from January 1987 to 15th of September 2021. We carry out an updated systematic review involving 5862 patients initially selected for fertility-sparing surgery in 275 series. FINDINGS: In patients having a stage IB1 disease, recurrence rate/RR in patients undergoing simple conisation/trachelectomy, radical trachelectomy/RT by laparoscopico-vaginal approach, laparotomic or laparoscopic approaches are respectively: 4.1%, 4.7%, 2.4% and 5.2%. In patients having a stage IB2 disease, RR after neoadjuvant chemotherapy or RT by laparotomy are respectively 13.2% and 4.8% (p = .0035). After neoadjuvant treatment a simple cone/trachelectomy was carried out in 91 (30%) patients and a radical one in 210 (70%) cases. But the lowest pregnancy rate is observed in patients undergoing RT by laparotomy (36%). CONCLUSIONS: The choice between these treatments should be based above all, on objective oncological data that strike a balance for each procedure between the best chances for cure and the fertility results. In patients having a stage IB1 disease, oncological results are quite similar according to the procedure used. In patients having a stage IB2 disease, RT by open approach has the lowest RR. Anyway the lowest pregnancy rate is observed in patients undergoing RT by laparotomy.

RESUMO

PURPOSE: Interstitial brachytherapy is indicated as part of a conservative strategy for children with bladder and/or prostate rhabdomyosarcoma (RMS), providing high local control probability with acceptable functional results. Vaginal and/or rectal complications were however reported, due to the close proximity to the implanted volume. We investigated the dosimetric impact of a vaginal spacer in terms of rectal and vaginal doses. METHODS AND PATIENTS: Medical records of 12 consecutive female patients with bladder neck RMS, median age 32 months (range: 1.3-6 years), were reviewed. Five patients were treated prior to 2017 without a vaginal spacer and seven patients treated after 2017 had their brachytherapy delivered with a vaginal spacer placed at time of implant. RESULTS: Minimal doses delivered to the most exposed 2cm3, 1cm3, and 0.5cm3 of the rectum were all statistically significantly lower among patients treated with a vaginal spacer, as compared to those treated without a spacer. Median rectal D2cm3 was 22GyEQD2 versus 38GyEQD2 (P=0.02), D1cm3 was 29GyEQD2 versus 51GyEQD2 (P=0.013), and D0.5cm3 was 32GyEQD2 versus 61GyEQD2 (P=0.017), with and without the vaginal spacer, respectively. The posterior vaginal wall D0.5cm3 dose was also significantly decreased, with median D0.5cm3 of 92GyEQD2 versus 54GyEQD2 (P<0.0001), with and without the spacer, respectively. Acute tolerance was excellent in all patients, with no need for replanning and no acute complication. CONCLUSIONS: The use of vaginal spacers in brachytherapy of female pediatric patients with bladder neck RMS resulted in significantly decreased doses to the rectum and the posterior vaginal wall. Though the clinical impact of such dose reduction remains undemonstrated, routine utilization of a vaginal spacer could be a method to decrease long-term morbidity in these patients.

RESUMO

PURPOSE: Adjuvant external beam radiotherapy (EBRT) was shown to decrease pelvic relapses in patients with an early stage cervical cancer and intermediate-risk histopathological prognostic factors, at the cost of increased bowel morbidity. We examined the feasibility and results of adjuvant brachytherapy alone as an alternative to EBRT in this situation. PATIENTS AND METHODS: Medical records of consecutive patients receiving adjuvant brachytherapy between 1991 and 2018 for an early stage cervical cancer were examined. Patients were included if they presented a pT1a2N0 or pT1b1N0 disease following radical colpohysterectomy. Adjuvant vaginal wall brachytherapy (without EBRT) was indicated because of a tumor size≥2cm and/or presence of lymphovascular space invasion (LVSI). Patients received 60Gy to 5mm of the vaginal wall, through low-dose or pulse-dose rate technique. Patients' outcome was examined for disease control, toxicities and prognostic factors. RESULTS: A total of 40 patients were included. Eight patients (20%) had LVSI, 26 patients (65%) had a tumor size≥2cm. With median follow-up time of 42.0 months, 90% of patients were in complete remission and four patients (10%) experienced tumor relapse, all in the peritoneal cavity, and associated with synchronous pelvic lymph node failure in 2/4 patients. No vaginal or isolated pelvic nodal failure was reported. At 5 year, overall survival was 83.6% (CI95%: 67.8-100%) and disease-free survival was 85.1% (CI95%: 72.6-99.9%). In univariate analysis, probability of relapse correlated with tumor size≥3cm (P=0.004). No acute or late toxicity grade more than 2 was reported. CONCLUSION: Brachytherapy alone was a well-tolerated adjuvant treatment for selected patients with intermediate risk factors. The risk of relapse in patients with tumor size≥3cm was however high, suggesting that EBRT is more appropriate in this situation.

RESUMO

Brachytherapy is part of the treatment of locally advanced cervical cancers, accounting for about half of the total delivered dose. The benefit of dose escalation is the most important in advanced cases or if the tumor has responded poorly. The use of interstitial implantations makes it possible to reach doses of the order of 85 to 90Gy (including external beam radiotherapy contribution) in most patients, through image-guided approaches. Brachytherapy delivery is one of the quality criteria for patient care. To date, no data allow us to consider as an alternative the use of external boost through intensity-modulated or stereotactic body radiotherapy. Indeed, the doses delivered to the tumor and the capacity to spare normal tissues remains lower, as compared to what is permitted by brachytherapy. It is therefore appropriate for centers that do not have access to the technique to establish networks with centers where brachytherapy is performed, to allow each patient to have access to the technique. It is also necessary to promote brachytherapy teaching. The issue of reimbursement will be crucial in the coming years to maintain expertise that is today insufficiently valued in its financial aspects, but has a very high added value for patients.

RESUMO

OBJECTIVE: This study assessed outcomes of inoperable endometrial cancer (IEC) patients treated with definitive external beam radiation therapy (EBRT) followed by a 3D image-guided brachytherapy boost. METHODS: All consecutive patients treated with EBRT followed by 3D image-guided brachytherapy for IEC were retrospectively included. EBRT delivered a dose of 45Gy. Then, patients had an uterovaginal brachytherapy guided by 3D imaging. Clinical target volume (CTVBT) included the whole uterus and the initial disease extent. Gross tumour volume (GTVres) included the residual disease at time of brachytherapy. RESULTS: Twenty-seven patients were identified. Causes of inoperability were comorbidities (37%) or tumour loco regional extent (63%). Including EBRT and brachytherapy, the median D90 (minimal dose delivered to 90% of the volume) was 60.7 GyEQD2 (IQR = 56.4-64.2) for the CTVBT, and was 73.6 GyEQD2 (IQR = 64.1-83.7) for the GTVres. The median overall treatment time was 50 days (IQR = 46-54). The mean follow-up was 36.5 months (SD = 30.2). The cumulative incidence of local, pelvic and distant failures was 19% (n = 5), 7% (n = 2) and 26% (n = 7), respectively. Five-year overall survival was 63% (95% CI = 43-91). Late urinary and gastro intestinal toxicities ≥ grade 2 were reported in four (15%) and two patients (7%) respectively. No vaginal toxicity ≥ grade 2 was reported. CONCLUSIONS: EBRT followed by intracavitary brachytherapy seems to be an effective option for IEC. The implementation of 3D concepts at time of brachytherapy may contribute to high local control probability and low toxicity profile. Large scale retrospective or prospective data are needed to confirm these early data.

RESUMO

INTRODUCTION: Since dose escalation allowed by image-guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer (LACC), local relapses have become a rare event. Only scarce data are available on the outcome of patients experiencing a local relapse after IGABT. METHODS: Between 2004 and 2016, all consecutive patients treated at Gustave Roussy Institute for LACC and receiving concomitant chemoradiation and IGABT were analysed. Clinical and treatment-related prognostic factors for survival after local relapse were searched, in order to potentially identify patients requiring salvage treatment. RESULTS: Two hundred and fifty-nine patients were treated during this period. With a median follow-up of 4.1 years, 10.8% (n = 28) had a local relapse. Among these patients, 53.6% had synchronous lymph nodes or distant metastatic relapse and only 13 patients (5% of all patients) had isolated local relapse. After local relapse, median survival was 47 months and three patients were alive at last follow-up. Only three patients with local relapse could receive salvage surgery (10.7%). Metastases occurrence and pelvic wall involvement were the main contraindications (67.9%) for salvage surgery. Among the three patients treated with surgery, two are still alive at last follow-up without significant complication. Improved survival was observed among the two patients who could have surgery (p = .02). Local progression led to serious symptoms in 75% of patients. Only the time interval between brachytherapy and relapse (<1 year) was prognostic for 2-year overall survival (p = .005). CONCLUSION: Salvage surgery is feasible in a very low number of highly selected patients with local relapse following IGABT. Local failure is a major cause of severe local symptoms, confirming that every effort should be done to achieve long-term local control through dose escalation.

RESUMO

PURPOSE: Lung and some digestive tumours move during a respiratory cycle. Four-dimensional scanography (4D-CT) is commonly used in treatment planning to account for respiratory motion. Although many French radiotherapy centres are now equipped, there are no guidelines on this subject to date. We wanted to draw up a description of the use of the 4D-CT for the treatment planning in France. METHODS AND MATERIAL: We conducted a survey in all French radiotherapy centres between March and April 2017. RESULTS: One hundred and seventy-two were contacted. The participation rate was 88.37%. The use of the 4D-CT seems to be common and concerned planning for 15.28% of kidney and adrenal cancers, 19.72% of pancreatic cancers, 27.78% of oesophageal cancers and 73.24% of lung cancers in case of normofractionated treatments. The use of the 4D-CT was also widespread in the case of stereotactic body radiation therapy: with 61.11% in the case of pulmonary irradiation and 34.72% in the case of hepatic irradiation. Many centres declared they carried out several 4D-CT for treatment planning (29, 55% in case of stereotactic body radiation therapy for lung tumours and 20% for liver tumours). Private centres tend to repeat 4D-CT more. CONCLUSION: Although the use of the 4D-CT appears to be developing, it remains very heterogeneous. To date, the repetition of the 4D-CT has been very poorly studied and could be the subject of clinical studies, allowing to define in which indications and for which populations there is a real benefit.

RESUMO

The small intestine is an organ frequently exposed in abdominal and pelvic irradiations. Acute and late toxicity can sometimes be difficult to manage and can significantly affect the quality of life of patients. Currently there is no guideline on the management of acute and late side effects induced by therapeutic irradiation. The aim of this review is to summarize available data on the pathophysiology of radiation enteritis, and to highlight potential preventive strategies and principles of treatment of radiation enteritis.

RESUMO

PURPOSE: The aim of the present study was to identify management strategies and outcomes of patients with stage IB1 cervical cancer with high recurrence risk. MATERIALS AND METHODS: Medical files of all consecutive patients treated between 2004 and 2017 with external beam radiotherapy and/or brachytherapy for IB1 cervical cancer, whatever the lymph node status, were retrospectively reviewed. RESULTS: Forty-two patients were included, with a median age of 49.8 years old. Median tumour size, estimated with the initial pelvic magnetic resonance imaging, was 26mm (interquartile range [IQR]=19.5-35). Histological types were mainly squamous cell carcinoma (59.5%) and adenocarcinoma (33.3%). Lymphovascular invasion was reported for 38.1% of patients. Pelvic lymph nodes were involved for eight patients (19.0%). Surgery was performed for 39 patients (92.9%). A neoadjuvant treatment was delivered for 20 patients (47.6%), an adjuvant treatment for 19 patients (45.2%) and an exclusive radiotherapy (with or without chemotherapy) followed by brachytherapy for three patients (7.1%). Pathologic complete response was achieved in 61.5% of patients. With a median follow-up of 5.8 years (IQR=2.6-9.4), five patients (11.9%) experienced a tumour relapse. The five-year disease-free survival was 79.5% (95% confident interval [CI]=66.9-94.4), the five-year overall survival was 87.8% (95% CI=77.2-99.8), and the five-year disease-specific survival was 94.2% (95% CI=86.7-100). CONCLUSION: In current clinical practice, tailored treatments are delivered, and seems to give correct therapeutic index. However, clinical trials are needed to standardise treatment according to patient characteristics and recurrence risk factors.

RESUMO

Intensity-modulated radiation therapy reduces the dose to organs at risk in patients treated for gynecological malignancies. Given the steep dose gradients around the planning target volume, internal movement of organs during treatment may cause a planning target volume underdosage and organs at risk overdosage in case of systematic error. It is therefore important to take into account the movement of the pelvic organs and to investigate potential solutions provided by image-guided radiotherapy. A review of the literature was carried out using the following databases: Medline, Embase, Cochrane Library, Web of Science, Cinahl and Pubmed. Appropriate search strategies for each database were applied based upon the following terms "uterine neoplasms, image-guided radiotherapy, adaptive radiotherapy, organ motion and target volume". These studies show that uterine motion is mainly influenced by bladder filling and by cervix and vaginal vault motion due to rectal filling. Population-based clinical target volume-planning target volume margins are large resulting in unnecessary organs at risk inclusion within the planning target volume, reducing the benefits of intensity-modulated radiotherapy. As pelvic organ motion seems to be patient specific, individualised planning target volume margins and adaptive radiotherapy strategies could allow adequate coverage of the planning target volume and increase organs at risk savings. In this study, we review the different techniques of image-guided radiotherapy and the perspective of adaptive radiotherapy.

RESUMO

BACKGROUND: Safety profile of the interaction between anticancer drugs and radiation is a recurrent question. However, there are little data regarding the non-anticancer treatment (NACT)/radiation combinations. The aim of the present study was to investigate concomitant NACTs in patients undergoing radiotherapy in a French comprehensive cancer center. METHODS: A prospective cross-sectional study was conducted. All cancer patients undergoing a palliative or curative radiotherapy were consecutively screened for six weeks in 2016. Data on NACTs were collected. RESULTS: Out of 214 included patients, a NACT was concomitantly prescribed to 155 patients (72%), with a median number of 5 NACTs per patient (range: 1-12). The most prescribed drugs were anti-hypertensive drugs (101 patients, 47.2%), psychotropic drugs (n = 74, 34.6%), analgesics (n = 78, 36.4%), hypolipidemic drugs (n = 57, 26.6%), proton pump inhibitors (n = 46, 21.5%) and antiplatelet drugs (n = 38, 17.8%). Although 833 different molecules were reported, only 20 possible modifiers of cancer biological pathways (prescribed to 74 patients (34.5%)) were identified. Eight out of the 833 molecules (0.9%), belonging to six drug families, have been investigated in 28 ongoing or published clinical trials in combo with radiotherapy. They were prescribed to 63 patients (29.4%). CONCLUSION: Drug-radiation interaction remains a subject of major interest, not only for conventional anticancer drugs, but also for NACTs. New trial designs are thus required.

RESUMO

BACKGROUND: Phase III randomized controlled trials (RCTs) are the cornerstone of evidence-based oncology. However, there is no exhaustive review describing the radiotherapy RTCs characteristics. The objective of the present study was to describe features of all phase III RCTs including at least a radiation therapy. METHODS AND MATERIALS: Requests were performed in the Medline database (via PubMed). The latest update was performed in April 2016, using the following MESH terms: 'clinical trials: phase III as topic', 'radiotherapy', 'brachytherapy', as keywords. RESULTS: A total of 454 phase III RCTs were identified. Studies were mainly based on open (92.1%) multicenter (77.5%) designs, analyzed in intend to treat (67.6%), aiming at proving superiority (91.6%) through overall survival assessment (46.5%). Most frequently studied malignancies were head and neck (21.8%), lung (14.3%) and prostate cancers (9.9%). Patients were mainly recruited with a locally advanced disease (73.7%). Median age was 59 years old. Out of 977 treatment arms, 889 arms experienced radiotherapy, mainly using 3D-conformal radiotherapy (288 arms, 32.4%). Intensity-modulated techniques were tested in 12 arms (1.3%). The intervention was a non-cytotoxic agent addition in 89 studies (19.6%), a radiation dose/fractionation modification in 74 studies (16.3%), a modification of chemotherapy regimen in 63 studies (13.9%), a chemotherapy addition in 63 studies (13.9%) and a radiotherapy addition in 53 trials (11.7%). With a median follow-up of 50 months, acute all-grade and grade 3-5 toxicities were reported in 49.6% and 69.4% of studies, respectively. Radiotherapy technique, follow-up and late toxicities were reported in 60.1%, 74%, and 31.1% of studies, respectively. CONCLUSION: Phase III randomized controlled trials featured severe limitations, since a third did not report radiotherapy technique, follow-up or late toxicities. The fast-paced technological evolution creates a discrepancy between literature and radiotherapy techniques performed in daily-routine, suggesting that phase III methodology needs to be reinvented.

Radiation-induced lung injuries mainly include the (acute or sub-acute) radiation pneumonitis, the lung fibrosis and the bronchiolitis obliterans organizing pneumonia (BOOP). The present review aims at describing the diagnostic process, the current physiopathological knowledge, and the available (non dosimetric) preventive and curative treatments. Radiation-induced lung injury is a diagnosis of exclusion, since clinical, radiological, or biological pathognomonic evidences do not exist. Investigations should necessarily include a thoracic high resolution CT-scan and lung function tests with a diffusing capacity of the lung for carbon monoxide. No treatment ever really showed efficacy to prevent acute radiation-induced lung injury, or to treat radiation-induced lung fibrosis. The most promising drugs in order to prevent radiation-induced lung injury are amifostine, angiotensin-converting-enzyme inhibitors and pentoxifylline. Inhibitors of collagen synthesis are currently tested at a pre-clinical stage to limit the radiation-induced lung fibrosis. Regarding available treatments of radiation-induced pneumonitis, corticoids can be considered the cornerstone. However, no standardized program or guidelines concerning the initial dose and the gradual tapering have been scientifically established. Alternative treatments can be prescribed, based on clinical cases reporting on the efficacy of immunosuppressive drugs. Such data highlight the major role of the lung dosimetric protection in order to efficiently prevent radiation-induced lung injury.

RESUMO

Each year, 15,000 head and neck cancer are treated in France. Prognosis is steadily improving. Consequently, limitation of late toxicities becomes essential. Ototoxicity is common, disabling and undervalued. We aimed to inventory primary, secondary and tertiary prevention measures to reduce ototoxicity induced by radiotherapy and chemotherapy, as well as its impact on quality of life of patients treated for head and neck cancer. External radiation therapy induced 30 to 40% of ototoxicity, including irreversible sensorineural hearing loss. Primary prevention of this risk is based on limiting the dose to the cochlea: 40Gy in case of radiotherapy alone, 10Gy during concomitant chemoradiotherapy with cisplatin. Dose gradients allowed by intensity-modulated radiotherapy help respecting these limits. Concurrent chemotherapy with high dose cisplatin (100mg/m2) also causes hearing loss by cochlear damages. Prescription of carboplatin-5-fluorouracil combination or cetuximab should be preferred in case of high risk of ototoxicity. This risk must be precisely evaluated before treatment. Ototoxicity monitoring during treatment allows early management, and lower long-term impact. Radiosensitivity predictive tests and research of genetic factors predisposing to chemo-induced ototoxicity should enable optimization of therapeutic choices and monitoring.

RESUMO

INTRODUCTION: The aim of this study was to appreciate the place and role of geriatric assessment in elderly patients with prostate cancer. MATERIALS AND METHODS: We performed a retrospective analysis of prostate cancer patients who underwent geriatric assessment during the therapeutic management from 2008 to 2014. Patient, tumor, treatment characteristics and their associated toxicity as well as the parameters of geriatric assessment were studied. The occurrence of geriatric assessment within the 3 months preceding a therapeutic decision was reviewed. RESULTS: Data of seventy-four patients were analyzed with a median follow-up of 15.6 years. The average age at diagnosis was 74.3 and 80.6 at the geriatric assessment. At the time of the geriatric assessment 64 patients had metastatic disease, 39 were in poor condition more than 50% of patients had walking ability disorders. Thirteen patients underwent radical surgery, 28 received radiotherapy, 30 patients had chemotherapy and hormonotherapy was prescribed for 72 patients. The geriatric assessment, requested on average 15 years after diagnosis, was not carried out within the 3 months preceding treatment decision for 55 patients. CONCLUSION: The recourse to geriatric assessment is predominantly used to endorse a decision of supportive care for elderly patients with prostate cancer. An early intervention by a geriatrician consultant for the initial management and then at each therapeutic event is a sine qua non condition for efficient personalized therapeutic management suitable to every patient according to physiological age. LEVEL OF EVIDENCE: 4.

RESUMO

Worldwide, more than a million people receive each year a curative radiotherapy. While local control and overall survival are steadily increasing, 5 to 15% of patients still develop above grade 2 late toxicities. Late toxicities treatments are complex. Hyperbaric oxygenation was shown to induce revascularization and healing of injured tissues, but indications are still debated. Through a literature review, we summarized the hyperbaric oxygenation indications in radiation-induced late toxicities. We also studied the knowledge and practice of French local radiation therapists. It seems that hyperbaric oxygen therapy can be a conservative treatment of haemorrhagic cystitis and radiation-induced pain, in case of drug therapies failure. Often associated with a significant morbidity and mortality, surgery could be avoided. The risk of complications in case of tooth extraction in irradiated tissues is also reduced. However, the role of hyperbaric oxygenation for mandibular osteoradionecrosis, radiation-induced proctitis, enteritis, lymphoedema, brachial plexopathy, skin and neurological sequelae seems more questionable since studies results are conflicting. Future outcomes of phase III studies are expected to clarify the role of hyperbaric oxygenation in the management of radio-induced toxicities, including for head and necks complications.

RESUMO

Rhabdomyosarcoma, most common soft tissue tumor in children, represent 8% of solid tumors in children. Conversely, in adults, this histology is very rare and no consensual recommendation is supported. If gynecological localization is one of the most frequent in children, it is a minority in adults. The management of this type of tumor is based on treatment multimodality combining surgery, chemotherapy, radiotherapy and brachytherapy. This pathological separate entity differs from other sarcomas by its greater sensitivity to chemotherapy and radiotherapy. The aim of this study is to conduct a general review of diagnostic and treatment of genital tract rhabdomyosarcoma in adults, and to report pathological characteristics of this type of tumor.

RESUMO

PURPOSE: An increasing attention is being paid to disclosures of conflicts of interests in the field of oncology. The purpose of this study was to examine how radiation oncologists report their conflicts of interests with pharmaceutical or technology industries. MATERIALS AND METHODS: We collected the data of conflicts of interests disclosures in the abstract books from the annual 2012 and 2013 meetings of the American Society for Radiation Oncology (ASTRO) in Miami (FL, USA), and in Atlanta (GA, USA), respectively. Geographic origins of abstracts as well other factors were examined. RESULTS: We identified a total of 4219 abstracts published in the past two years. The total number of involved authors was of 28,283. All of the published abstracts had conflicts of interests disclosures. Amongst them, 563 abstracts (13.4%) reported at least one potential conflict of interests, in which 1264 (4.5%) declared a potential conflict of interests in their disclosures. Geographic distribution of abstracts with financial relationship was as following: 67.9%, 15.5%, 7.7% and 7.7% for USA, Europe, Asia/Pacifica, and Canada, respectively. Abstracts with conflict of interest originated from North America in 75.6% of cases. USA distribution was 70.6% and 29.4% for Eastern and Western, respectively. CONCLUSIONS: The proportion of physicians declaring financial conflicts of interests remains extremely low, whichever geographic area authors are from. In comparison to the rest of the world, the US proved itself better at declaring potential links. Changes in medical culture and education could represent a significant step to improve the process of revealing conflicts of interest in medical journal as well as in international meetings.
