RESUMO
OBJECTIVE: To report the results of a multicenter cohort of preoperative brachytherapy (PBT) for treatment of early-stage cervical cancer (ESCC). METHODS: A retrospective analysis was conducted among five French comprehensive cancer centers on behalf of the SFRO Brachytherapy Group to examine the outcome of patients with ESCC who received PBT between 2001 and 2019 because of adverse prognostic factors (tumor size >2 cm, presence of lymphovascular invasion, adenocarcinoma).Brachytherapy was followed 4-8 weeks later by surgery. Local relapse free, distant metastasis-free survival, disease-free, and overall survival and adverse effects were examined. Uni- and multivariate analyses were conducted looking for oncological prognostic factors. RESULTS: A total of 451 patients were identified, with a mean tumor size of 24.7 mm. Adenocarcinoma accounted for 43.5% of cases, and lympho-vascular space invasion (LVSI) was present in 15.7%. A complete histological response was observed in 69.6%. With a mean follow-up of 75.4 months, DFS, LRFS, and OS rates at five years were 88% [95% CI (84-91), 98% [95% CI (96-99), and 92% [95% CI (87-95)], respectively. At the last follow-up, 8.2% of patients had died, including 31 (6.8%) from cervical cancer. Severe side effects range from 1.1% to 2%. At multivariate analysis, adenocarcinoma histological type, tumor size ≥2 cm, and the presence of residual tumors were prognosticators for DFS and DMFS. CONCLUSION: PBT shows excellent oncological outcomes in this cohort of patients with adverse histoprognostic factors. Favorable survival rates and low complications rates were observed, supporting this strategy in the management of ESCC.

BACKGROUND: Spatial inequalities in cancer management have been evidenced by studies reporting lower quality of care or/and lower survival for patients living in remote or socially deprived areas. NETSARC+ is a national reference network implemented to improve the outcome of sarcoma patients in France since 2010, providing remote access to specialized diagnosis and Multidisciplinary Tumour Board (MTB). The IGéAS research program aims to assess the potential of this innovative organization, with remote management of cancers including rare tumours, to go through geographical barriers usually impeding the optimal management of cancer patients. METHODS: Using the nationwide NETSARC+ databases, the individual, clinical and geographical determinants of the access to sarcoma-specialized diagnosis and MTB were analysed. The IGéAS cohort (n = 20,590) includes all patients living in France with first sarcoma diagnosis between 2011 and 2014. Early access was defined as specialised review performed before 30 days of sampling and as first sarcoma MTB discussion performed before the first surgery. RESULTS: Some clinical populations are at highest risk of initial management without access to sarcoma specialized services, such as patients with non-GIST visceral sarcoma for diagnosis [OR 1.96, 95% CI 1.78 to 2.15] and MTB discussion [OR 3.56, 95% CI 3.16 to 4.01]. Social deprivation of the municipality is not associated with early access on NETSARC+ remote services. The quintile of patients furthest away from reference centres have lower chances of early access to specialized diagnosis [OR 1.18, 95% CI 1.06 to 1.31] and MTB discussion [OR 1.24, 95% CI 1.10 to 1.40] but this influence of the distance is slight in comparison with clinical factors and previous studies on the access to cancer-specialized facilities. CONCLUSIONS: In the context of national organization driven by reference network, distance to reference centres slightly alters the early access to sarcoma specialized services and social deprivation has no impact on it. The reference networks' organization, designed to improve the access to specialized services and the quality of cancer management, can be considered as an interesting device to reduce social and spatial inequalities in cancer management. The potential of this organization must be confirmed by further studies, including survival analysis.

OBJECTIVE: The standard of care for early cervical cancer is radical hysterectomy; however, consideration of pre-operative brachytherapy has been explored. We report our experience using pre-operative brachytherapy plus Wertheim-type hysterectomy to treat early stage cervical cancer. METHODS: This single-center study evaluated consecutive patients with histologically proven node-negative early stage cervical cancer (International Federation of Gynecology and Obstetrics 2009 stage IB1-IIB) that was treated using pre-operative brachytherapy and hysterectomy. Pre-brachytherapy staging was performed using magnetic resonance imaging (MRI) and pelvic lymph node assessment was performed using lymphadenectomy. The tumor and cervical tissues were treated using brachytherapy (total dose 60 Gy) followed by Wertheim-type hysterectomy. The study included patients from January 2000 to December 2013. RESULTS: A total of 80 patients completed a median follow-up of 6.7 years (range 5.4-8.5). The surgical specimens revealed a pathological complete response for 61 patients (76%). Patients with incomplete responses generally had less than 1 cm residual tumor at the cervix, and only one patient had lymphovascular space involvement. The estimated 5-year rates were 88% for overall survival (95% CI 78% to 94%) and 82% for disease-free survival (95% CI 71% to 89%). Toxicities were generally mild-to-moderate, including 26 cases (33%) of grade 2 late toxicity and 10 cases (13%) of grade 3 late toxicity. Univariate analyses revealed that poor disease-free survival was associated with overweight status (≥25 kg/m2, HR 3.05, 95% CI 1.20 to 7.76, p=0.019) and MRI tumor size >3 cm (HR 3.05, 95% CI 1.23 to 7.51, p=0.016). CONCLUSIONS: Pre-operative brachytherapy followed by Wertheim-type hysterectomy may be safe and effective for early stage cervical cancer, although poorer outcomes were associated with overweight status and MRI tumor size >3 cm.

BACKGROUND: Extended-field chemoradiation therapy is usually performed in patients with locally advanced cervical cancer (LACC) and paraaortic (PA) node metastases. Considering the very low rate of skip metastases above inferior mesenteric artery, ilio-inframesenteric paraaortic lymph node dissection (IM-PALND) seems to be an adequate pattern of PALND. Our objective was to assess the accuracy of this management to determine PA nodal status in comparison with infrarenal paraaortic lymphadenectomy (IR-PALND) in case of squamous or glandular cervical cancer. METHODS: All patients with LACC and negative MRI and PET/CT imaging at paraaortic level had laparoscopic staging (followed, if negative, by extraperitoneal paraaortic lymphadenectomy). From January 2011 to September 2015, patients who had IM-PALND were included and were compared to a previous historical series of IR-PALND patients. The two groups differed only at the upper level of dissection. Characteristics of nodal involvement at paraaortic level depending on level of dissection, PET/CT imaging and histology were studied. RESULTS: 119 women were included in our study, with 56 patients in the IM-PALND group and 63 in the IR-PALND group. In the IM-PALND group, fewer nodes were resected (p<0.001). There was no difference between the two groups regarding nodal status at paraaortic level (p=0.77). Patterns of nodal involvement were similar whichever the histological subtype of cervical cancer (squamous or glandular). CONCLUSION: IM-PALND appears to be equally effective to assess paraaortic nodal involvement in LACC for both histological subtypes - glandular and squamous carcinomas - and to select patients for extended-field chemoradiation therapy.

OBJECTIVE: Extended-field chemoradiation is typically used for the management of patients with locally advanced cervical cancer. Given the low rate of skipped metastases above the inferior mesenteric artery, ilioinframesenteric dissection seems to be an acceptable pattern of paraaortic lymph node dissection (LND). Our objective is to compare the surgical morbidity of inframesenteric LND (IM-LND) with infrarenal LND (IR-LND). METHODS: In our center, all of the patients with locally advanced cervical cancer and negative magnetic resonance imaging and positron emission tomography-computed tomography imaging at the paraaortic level were offered laparoscopic staging including a diagnostic laparoscopy followed, if negative, by an extraperitoneal paraaortic lymphadenectomy. From January 2011 to September 2015, we included patients who had paraaortic LND from both common iliac bifurcations and divided them into 2 groups according to dissection pattern: to the inferior mesenteric artery (IM-LND) level or to the left renal vein (IR-LND) level. The perioperative and postoperative data were retrospectively recorded. RESULTS: A total of 119 women were included in our study: 56 in the IM-LND group and 63 in the IR-LND group. There was no difference in the patients' characteristics between groups. Regarding the surgical procedure, the operating time was shorter in the IM-LND group than the IR-LND group, 174 ± 50 minutes versus 209 ± 61 minutes (P = 0.001), respectively. There was no significant difference in intra- and postoperative complications, overall survival, or progression-free survival. CONCLUSIONS: In our series, exclusive IM-LND surgery is faster than IR-LND and results in similar morbidity and survival rates. These results confirm the feasibility and the applicability of IM-LND to simplify the surgical procedure without impacting survival. More patients should be included in the study to demonstrate the lower rate of morbidity.

BACKGROUND: After the diagnosis of occult cervical cancer during simple hysterectomy, is the best treatment option for the patient surgery with or without radiotherapy or radiation therapy only? Our study aims to answer this question. MATERIALS AND METHODS: We retrospectively analyzed 29 patients with occult cervical cancer found after inadvertent simple hysterectomy and who were referred to our cancer center between 2000 and 2010. All of the patients were discussed by the tumor board. Thirteen patients underwent surgery (radical parametrectomy and pelvic lymphadenectomy) using the minimally invasive approach (surgical group), and 16 patients underwent pelvic lymphadenectomy and radiation therapy or concurrent chemoradiation (radiation group). RESULTS: Age, BMI, and the tumor diameter were not statistically different between the surgical and radiation group: 44 and 49 (± 11) years (p = .23), 24.6 (± 6.2) and 26.7 (± 5) (p = 0.33), and 22 (± 13) and 31 (± 11) mm (p = .09), respectively. The 5-year overall and disease-free survivals for the surgical and radiation groups were: 100 and 77 % (p = .04), and 86 and 37 % (p = .02), respectively. These results were statistically significant. CONCLUSIONS: In the case of occult cervical cancer found after simple hysterectomy, radical parametrectomy with pelvic lymphadenectomy using minimally invasive surgery seems to be more efficient than radiation therapy or concurrent chemoradiation, with acceptable minimal morbidity being observed.

PURPOSE: In November 2010, the French National Cancer Institute published new guidelines for managing endometrial cancer. Pelvic lymphadenectomy is not indicated for preoperative low-intermediate risk type 1 endometrial cancer, and high-risk patients should undergo secondary surgery with para-aortic lymphadenectomy. This study evaluated these new guidelines with regard to overall survival (OS), relapse-free survival (RFS), and morbidity for patients with low-intermediate risk disease. METHODS: We evaluated all type 1 endometrial cancer patients with low-intermediate risk of recurrence who were treated from 1 January 1997 through 31 December 2012. All patients were classified according to the 2009 International Federation of Gynecology and Obstetrics staging criteria and the European Society for Medical Oncology. RESULTS: Overall, 230 patients were included (159 before and 71 after the new guidelines were issued). Pelvic lymphadenectomies were performed before and after the new guidelines in 77.4 and 28.6 % of patients, respectively (p < 0.001). After 2010, eight patients also underwent secondary surgery, which consisted of a para-aortic lymphadenectomy for lymphovascular space invasion (LVSI). This second surgery changed the adjuvant treatment for one patient. OS and RFS were similar between both groups, and no difference in morbidity was observed between the groups. LVSI was an independent factor for OS [hazard ratio (HR) 7.2, 95 % CI 3.1-17; p < 0.001] and RFS (HR 3.7, 95 % CI 1.6-8.5; p < 0.003). CONCLUSIONS: Fewer pelvic lymphadenectomies in low-intermediate risk patients did not affect OS, RFS, or morbidity, including patients with secondary surgery. We must gather additional data with a longer follow-up period to not only confirm our results but to also fully investigate the paradoxical absence of decreased morbidity that our study has shown.

AIM: To report a single-institution experience using postoperative pelvic Intensity Modulation Radiation Therapy (IMRT) using tomotherapy accelerators (TA) in postoperative endometrial cancer (EC) regarding ICRU 83 recommendations. BACKGROUND: IMRT in gynecological malignancies provides excellent dosimetric data, lower rates of adverse events and clinical data similar to historical series. MATERIAL AND METHODS: Seventy-six patients with EC were postoperatively treated with adjuvant IMRT using TA. The IMRT dose was 45 Gy for patients without positive lymph nodes and Type I histology and 50.4 Gy for patients with positive lymph nodes and/or type II histology. RESULTS: With a median follow-up of 29 months, the 12- and 24-month Overall Survival (OS) and Disease-Free Survival (DFS) were 96%, 93%, 87%, and 74%, respectively. Age of less than 60 years was associated with better OS (HR: 8.9; CI: 1.1-68) and DFS (HR: 3.5; CI: 1.2-10.2). Patients with Type II and Type I Grade III histology had a worse OS (HR: 3.3; CI: 1.1-11). Five women (6.6%) presented in-field local vaginal recurrence, 2 (2.6%) presented non-in-field vaginal recurrence, 4 (5.2%) presented pelvic node and distant recurrence and 11 (14.4%) presented only distant metastases. One patient stopped radiation treatment due to Grade III acute diarrhea. No Grade III late toxicity was observed. Planning Target Volume (PTV) coverage showed mean D2, D50, D95, and D98 of 51.64-46.23 Gy, 49.49-44.97 Gy, 48.62-43.96 Gy, and 48.47-43.58 Gy for patients who received 45 and 50.4 Gy, respectively. CONCLUSIONS: IMRT with TA in postoperative EC shows excellent conformity and homogeneity of PTV dose. Without Grade III late toxicity, data from this cohort demonstrated the utility of IMRT.
RESUMO
OBJECTIVE: Brachytherapy of the vaginal dome is the recommended adjuvant treatment for intermediate-risk endometrial cancer. This study assessed the results of dosimetric planning of high-dose-rate brachytherapy exclusively in the first treatment session. STUDY DESIGN: This retrospective study included all patients who underwent hysterectomy for endometrial cancer followed by adjuvant brachytherapy of the vaginal dome between 2012 and 2015. Local recurrence rates, overall survival (OS) rates, recurrence-free survival (RFS) rates, and related acute and late toxicity rates were evaluated. RESULTS: This analysis included 250 patients, of whom 208 were considered to be at high-intermediate risk of disease recurrence. After a median follow-up of 56 months, the cumulative incidence of local recurrence was 4.8% at 3 years [95% confidence interval (CI) 2.8-8.3] and 7.8% at 5 years (95% CI 4.8-12.6). The 5-year OS rate was 86.2% (95% CI 80.6-90.3), and the 5-year RFS rate was 77.5% (95% CI 71.1-82.7). Acute toxicity occurred in 20 (8%) patients, of which two patients had grade ≥3 toxicity. Only one patient (0.4%) presented with late grade ≥3 toxicity. CONCLUSION: These findings confirm the tolerability of this brachytherapy approach, indicating minimal cases of late grade ≥3 toxicity, associated with a good 5-year OS rate. With the advent of molecular prognostic factors, the current focus revolves around discerning those individuals who gain the greatest benefit from adjuvant therapy, and tailoring treatment more effectively.

Background and purpose: Image-guided adapted brachytherapy (IGABT) is superior to other radiotherapy techniques in the treatment of locally advanced cervical cancer (LACC). We aimed to investigate the benefit of interstitial needles (IN) for a combined intracavitary/interstitial (IC/IS) approach using IGABT over the intracavitary approach (IC) alone in patients with LACC after concomitant external beam radiotherapy (EBRT) and chemotherapy. Materials and methods: We included consecutive patients with LACC who were treated with IC/IS IGABT after radiochemotherapy (RCT) in our retrospective, observational study. Dosimetric gain and sparing of organs at risk (OAR) were investigated by comparing the IC/IS IGABT plan with a simulated plan without needle use (IC IGABT plan) and the impact of other clinical factors on the benefit of IC/IS IGABT. Results: Ninety-nine patients were analyzed, with a mean EBRT dose of 45.5 ± 1.7 Gy; 97 patients received concurrent chemotherapy. A significant increase in median D90% High Risk Clinical target volume (HR-CTV) was found for IC/IS (82.8 Gy) vs IC (76.2 Gy) (p < 10-4). A significant decrease of the delivered dose for all OAR was found for IC/IS vs IC for median D2cc to the bladder (77.2 Gy), rectum (68 Gy), sigmoid (53.2 Gy), and small bowel (47 Gy) (all p < 10-4). Conclusion: HR-CTV coverage was higher with IC/IS IGABT than with IC IGABT, with lower doses to the OAR in patients managed for LACC after RCT. Interstitial brachytherapy in the management of LACC after radiotherapy provides better coverage of the target volumes, this could contribute to better local control and improved survival of patients.
RESUMO
INTRODUCTION: Myxoid liposarcoma is a soft tissue sarcoma associated with multifocal metastases at diagnosis. These metastases are asymptomatic and occult on CT and FDG-PET and can alter the therapeutic management and prognosis. In this context, we evaluated the contribution of whole-body MRI to the initial workup of patients with myxoid liposarcoma. METHOD: This retrospective study was conducted between January 2015 and December 2020 at the Oscar Lambret Center. We enrolled 22 patients who were diagnosed with myxoid liposarcoma and underwent whole-body MRI at diagnosis. The number of metastases at diagnosis, their location, and the visibility of these lesions on CT were evaluated. Associations between clinical features, presence of metastasis, and their impact on management were assessed. RESULTS: Sixteen patients (72.7%) had non-metastatic disease at the initial diagnosis, and 15 of these patients were managed using local treatment. Six patients (27.3%) had metastases at multiple locations and received chemotherapy. The main locations were the bones (n=5) and lungs (n=3). In five patients with metastases, whole-body MRI demonstrated additional lesions that were not visible on CT (bone and soft tissue lesions). Only the presence of a round cell contingent (P=0.009) was found as a criterion associated with the presence of metastases. CONCLUSION: The patients' young age, absence of reliable prognostic factors at diagnosis, asymptomatic nature of the lesions, and the benefits of early and targeted therapeutic management encourage the use of whole-body MRI as part of the initial work-up as it seems to provide a better initial staging compared with conventional imaging.

Vulvar cancer is a relatively rare neoplasm. The essential treatment is surgery for the primary tumour. However, postoperative recurrence rates are high, even in early-stage disease when tumour-free surgical margins are achieved or in the absence of associated risk factors (lymph node metastases, deep stromal invasion or invasion of the lymphatic vascular space). Radiotherapy plays an important role in the treatment of vulvar cancer. Adjuvant treatment after surgery as well as primary treatment of locally advanced vulvar cancer (LAVC) is composed of two key radiotherapy treatment scenarios, external beam radiation therapy (EBRT) either combined or not combined with brachytherapy (BT). In a recurrence setting, where surgery is not an option, BT alone or in combination with EBRT can be used. Compared to EBRT, BT has the radiobiological potential to improve dose to the target volume, minimise the dose to organs at risk, and facilitate hypofractionated-accelerated treatment. This narrative review presents recent data on the role of BT in the treatment of primary and/or recurrent vulvar cancer, including radiobiological, clinical, and therapeutic aspects.
RESUMO
(1) This study aims to evaluate the overall survival (OS) and recurrence-free survivals (RFS) and assess disease recurrence of early-stage cervical cancer (ESCC) patients treated with minimally invasive surgery (MIS). (2) This single-center retrospective analysis was performed between January 1999 and December 2018, including all patients managed with MIS for ESCC. (3) All 239 patients included in the study underwent pelvic lymphadenectomy followed by radical hysterectomy without the use of an intrauterine manipulator. Preoperative brachytherapy was performed in 125 patients with tumors measuring 2 to 4 cm. The 5-year OS and RFS rates were 92% and 86.9%, respectively. Multivariate analysis found two significant factors associated with recurrence: previous conization with HR = 0.21, p = 0.01, and tumor size > 3 cm with HR = 2.26, p = 0.031. Out of the 33 cases of disease recurrence, we witnessed 22 disease-related deaths. Recurrence rates were 7.5%, 12.9%, and 24.1% for tumors measuring ≤ 2 cm, 2 to 3 cm, and > 3 cm, respectively. Tumors ≤ 2 cm were mostly associated with local recurrences. Tumors > 2 cm were frequently associated with common iliac or presacral lymph node recurrences. (4) MIS may still be considered for tumors ≤ 2 cm subject to first conization followed by surgery with the Schautheim procedure and extended pelvic lymphadenectomy. Due to the increased rate of recurrence, a more aggressive approach might be considered for tumors > 3 cm.
RESUMO
OBJECTIVE: Evaluation of the management by first brachytherapy followed by radical hysterectomy (Wertheim type) compared to radical hysterectomy alone (Wertheim type) for the treatment of IB2 cervical cancer. METHODS: Data from women with histologically proven FIGO stage IB2 cervical cancer treated between April 1996 and December 2016 were retrospectively abstracted from twelve French institutions with prospectively maintained databases. RESULTS: Of the 211 patients with FIGO stage IB2 cervical cancer without lymph node involvement included, 136 had surgical treatment only and 75 had pelvic lymph node staging and brachytherapy followed by surgery. The surgery-only group had significantly more adjuvant treatment (29 vs. 3; p = 0.0002). A complete response was identified in 61 patients (81%) in the brachytherapy group. Postoperative complications were comparable (63,2% vs. 72%, p = 0,19) and consisted mainly of urinary (36vs. 27) and digestive (31 vs 22) complications and lymphoceles (4 vs. 1). Brachytherapy had no benefit in terms of progression-free survival (p = 0.14) or overall survival (p = 0.59). However, for tumors of between 20 and 30 mm, preoperative brachytherapy improved recurrence-free survival (p = 0.0095) but not overall survival (p = 0.41). This difference was not observed for larger tumors in terms of either recurrence-free survival (p = 0.55) or overall survival (p = 0.95). CONCLUSION: Our study found that preoperative brachytherapy had no benefit for stage IB2 cervical cancers in terms of recurrence-free survival or overall survival. For tumor sizes between 2 and 3 cm, brachytherapy improves progression-free survival mainly by reducing pelvic recurrences without improving overall survival.

BACKGROUND: Myositis ossificans circumscripta is a self-limiting, benign, ossifying lesion that can affect any type of soft tissue. It is most commonly found in muscles as a solitary lesion. A history of recent trauma has been reported in approximately 50% of cases. Clinically, MOC presents as a painful swelling, which rapidly increases in size. The pain and inflammatory symptoms spontaneously disappear after approximately 2-6 weeks, and the mass stabilizes or decreases. Radiologically, myositis ossificans circumscripta can be divided into two phases. The first is the acute phase, which is followed by the mature phase 2-6 weeks later. During the acute phase, the radiological aspect does not show any specific abnormality. In the mature phase, plain radiographs and computed tomography show blurred calcifications around a hypodense center. We describe here the first case of myositis ossificans circumscripta, with appropriate follow-up, occurring during sunitinib exposure. CASE PRESENTATION: We report a case of myositis ossificans circumscripta in a 34-year-old man (ethnicity unknown) receiving sunitinib for metastatic alveolar soft part sarcoma of the left thigh after surgery and radiotherapy. Four months after the first dose of sunitinib, the patient experienced painful swelling in the surgical scar area. Magnetic resonance imaging showed diffuse and marked edema of the anterior compartment of the thigh, without nodular lesions circumscribing a central core, and without bone signal abnormality. The increased visibility of the intermuscular fascia and convergence of normal muscle fibers (black hole effect), without the displacement seen in tumors, were suggestive of myositis. Therefore, antiangiogenic treatment was discontinued, and the symptoms rapidly resolved within a few days. Three weeks after the discontinuation of sunitinib, the inflammatory findings completely disappeared. Two months after the diagnosis of myositis ossificans circumscripta, plain radiographs and computed tomography showed an extensive calcified mass measuring > 12 cm. The continuation of favorable clinical outcomes was confirmed. CONCLUSIONS: To the best of our knowledge, this is the first case of myositis ossificans circumscripta with appropriate follow-up occurring during sunitinib exposure. Owing to multimodal treatment of sarcoma, we cannot rule out the radiotherapy and surgery causality.

Objective: Pelvic magnetic resonance imaging (MRI) is a key exam used for the initial assessment of loco-regional involvement of cervical cancer. In patients with locally advanced cervical cancer, MRI is used to evaluate the early response to radiochemotherapy before image-guided brachytherapy, the prognostic impact of which we aimed to study. Methods: Patients with locally advanced cervical cancer treated using concomitant radiochemotherapy followed by closure treatment between January 2010 and December 2015 were included in this study. Clinical, anatomopathological, radiological, therapeutic, and follow-up data were evaluated. Results: After applying the inclusion and exclusion criteria to the initially chosen 310 patients, 232 were included for evaluation (median follow-up period, 5.3 years). The median age was 50 years (range, 25-83 years), and the median tumor size was 47.5 mm (range, 0-105 mm). Based on the International Federation of Gynaecology and Obstetrics classification system, 9 patients were in stage IB2; 20, IB3; 2, IIA; 63, IIB; 4, IIIA; 7, IIIB; and 127, IIIC1 or higher. The re-evaluation MRI was performed at the median dose of 55.5 Gy, and median reduction in tumor size was 55.2% (range, -20-100%). There was a difference between the disease-free and overall survival rates of the patients with a tumor response greater or lesser than 50%. The risk of recurrence or death reduced by 39% in patients with a tumor size reduction >50%. The overall 5-year survival rate of patients with a response greater and lesser than 50% were 77.7% and 61.5%, respectively. The 5-year disease-free survival rate for these two groups of patients were 68.8% and 51.5%, respectively. Conclusion: Our study confirms the prognostic impact of tumor size reduction using MRI data obtained after radiochemotherapy in patients with locally advanced cervical cancer.
RESUMO
BACKGROUND AND PURPOSE: The Radiation Induced Sarcoma (RIS) is a rare but serious adverse event following radiotherapy (RT). Current RT techniques are more precise, but irradiate a larger volume at a low dose. This study aimed to describe radiation characteristics in a large series of patients suffering from RIS. MATERIALS AND METHODS: Patient-representative voxel-based anthropomorphic phantoms were used to reconstruct patient-specific RT fields for 125 patients diagnosed with RIS after primary breast cancer. For each patient, the location of the RIS onset site was determined and transferred onto the phantom as a contour. Using a treatment planning system (TPS), the dose distribution on the RIS in the phantom was calculated. RESULTS: The mean dose (Dmean) received in the area where RIS subsequently developed was 47.8 ± 11.6 Gy. The median dose in the zones where RIS later developed ranged from 11 Gy to 58.8 Gy. The median time from RT to RIS development was 8 years (range 2-32 years). Analysis for predictors of time to radiation-induced sarcoma development highlighted a significant impact of age of patient during the RT whereas in multivariable analysis chemotherapy and hormonotherapy for primary breast cancer were not associated with a significant difference in time to diagnosis of RIS. CONCLUSIONS: This study highlights that the dose received by the tissue in which the RIS developed was almost 47 Gy. These results are encouraging for the use of new RT techniques increasing volumes receiving low doses, without fear of an excess of RIS over the next 10 years.

We review the role of hormonal therapy in the management of different conjunctive tumors. Progestin and aromatase inhibitors seem active in low-grade endometrial stromal sarcoma, but larger case-series are needed. There is no evidence to support the use of hormonal therapy as an adjuvant treatment for low-grade endometrial stromal sarcoma. We did not find relevant data on the use of hormonal therapy for other uterine sarcomas (e.g., high-grade endometrial sarcoma, undifferentiated uterine sarcoma, and adenosarcoma). Gonadotropin-releasing hormone agonist, anti-estrogens and aromatase inhibitor seem active in advanced aggressive angiomyxoma, but larger studies are warranted. The use of aromatase inhibitor in estrogen-receptor-positive uterine leiomyosarcoma requires further clinical investigation. There is no evidence supporting the use of hormonal therapy in desmoid-type fibromatosis. International collaboration efforts are warranted to better explore the role of hormonal therapies in management of estrogen-receptor-positive uterine leiomyosarcoma, low-grade endometrial stromal sarcoma, and aggressive angiomyxoma.

Purpose: PET/CT is a standard medical imaging used in the delineation of gross tumor volume (GTV) in case of radiation therapy for lung tumors. However, PET/CT could present some limitations such as resolution and standardized uptake value threshold. Moreover, chest MRI has shown good potential in diagnosis for thoracic oncology. Therefore, we investigated the influence of chest MRI on inter-observer variability of GTV delineation. Methods and Materials: Five observers contoured the GTV on CT for 14 poorly defined lung tumors during three contouring phases based on true daily clinical routine and acquisition: CT phase, with only CT images; PET phase, with PET/CT; and MRI phase, with both PET/CT and MRI. Observers waited at least 1 week between each phases to decrease memory bias. Contours were compared using descriptive statistics of volume, coefficient of variation (COV), and Dice similarity coefficient (DSC). Results: MRI phase volumes (median 4.8 cm3) were significantly smaller than PET phase volumes (median 6.4 cm3, p = 0.015), but not different from CT phase volumes (median 5.7 cm3, p = 0.30). The mean COV was improved for the MRI phase (0.38) compared to the CT (0.58, p = 0.024) and PET (0.53, p = 0.060) phases. The mean DSC of the MRI phase (0.67) was superior to those of the CT and PET phases (0.56 and 0.60, respectively; p < 0.001 for both). Conclusions: The addition of chest MRI seems to decrease inter-observer variability of GTV delineation for poorly defined lung tumors compared to PET/CT alone and should be explored in further prospective studies.
