RESUMO

Preserving the quality of life and sexual function of patients with a localized prostate cancer remains a challenge for physicians and a major issue for patients. The present study aimed at demonstrating the feasibility of a dosimetric preservation of the sexual organs during prostate stereotactic radiotherapy planning. Patients from a single centre were retrospectively included in the RPAH-2 trial and randomized in Arm B if they presented with either a low- or intermediate- risk prostate cancer. A 37.5Gy in 5 fractions stereotactic body radiotherapy was delivered on the prostate gland. The corpus cavernosum, penile bulb and internal pudental arteries were retrospectively delineated before a re-optimization process. During this process, RPAH-2 trial dose constraints were respected on Gross Tumor Volume (GTV), Planning Target Volume and usual organs at risk. Pre-defined dose setting delivered to corpus cavernosum, penile bulb and internal pudental arteries were collected and compared before and after the re-optimization process. Nine patients were included in the study. A decrease of the median of each investigated dose setting (except D90% for corpus cavernosum) was reported after the re-optimization for corpus cavernosum, penile bulb and internal pudental arteries. Our study demonstrated the feasibility of a dosimetric preservation of structures considered as relevant to preserve sexual function after prostate stereotactic radiotherapy.

RESUMO

PURPOSE: Limited pelvic nodal relapse of prostatic cancer is a paramount challenge for locoregional salvage treatments. Salvage whole pelvis radiation therapy as considered in the BLINDED trial is an attractive option, but there are concerns about its toxicity. This article describes early toxicity with the technique. METHODS AND MATERIALS: BLINDED was a prospective multicenter phase 2 trial investigating high-dose salvage pelvic irradiation with an additional dose to the fluorocholine-based positron emission tomography-positive pelvic lymph nodes, combined with 6-month androgen blockade. The prescribed dose was 54 Gy in 1.8 Gy fractions with up to 66 Gy in 2.2 Gy fractions to the pathologic pelvic lymph nodes. Early toxicity was defined as toxicity until 1 year after radiation therapy. Patients quality of life was assessed using the European Organisation for Research and Treatment of Cancer questionnaires (QLQ-C30 and QLQ-PR25). RESULTS: Seventy-four patients were recruited in 15 French radiation oncology departments between August 2014 and July 2016. Seven were excluded before treatment because of violation of the inclusion criteria. The intention-to-treat analysis therefore included 67 patients. Half had received prior prostatic irradiation. Median age was 67.7 ± 6.5 years. Grade 2 acute urinary toxicity was observed in 9 of 67 patients (13.4%), and grade 2 1-year toxicity occurred in 4 of 67 patients (6%). Three patients (4.4%) had grade 3 urinary toxicity. Grade 2 acute digestive toxicity was observed in 10 of 67 patients (14.9%), and grade 2 1-year toxicity occurred in 4 of 67 patients (6%). Patients with prior prostate bed irradiation did not exhibit increased urinary or digestive toxicity. The European Organisation for Research and Treatment of Cancer questionnaire scores at 1 year did not worsen significantly. CONCLUSIONS: The acute and 1-year toxicity of the BLINDED protocol was satisfactory, even in patients with a history of prostatic irradiation.

RESUMO

This retrospective study was undertaken to provide more modern data of real-life management of non-metastatic rectal cancer, to compare therapeutic strategies, and to identify prognostic factors of overall survival (OS) in a large cohort of patients. Data on efficacy and on acute/late toxicity were retrospectively collected. Patients were diagnosed a non-metastatic rectal cancer between 2004 and 2015, and were treated at least with radiotherapy. OS was correlated with patient, tumor and treatment characteristics with univariate and multivariate analyses. Data of 593 consecutive non-metastatic rectal cancer patients were analyzed. Median follow-up was 41 months. Median OS was 9 years. Radiotherapy was delivered in pre-operative (n = 477, 80.5%), post-operative (n = 75, 12.6%) or exclusive (n = 41, 6.9%) setting. In the whole set of patients, age, nutritional condition, tumor stage, tumor differentiation, and surgery independently influenced OS. For patients experiencing surgery, OS was influenced by age, tumor differentiation and nodal status. Surgical resection is the cornerstone treatment for locally-advanced rectal cancer. Poor tumor differentiation and node involvement were identified as major predictive factor of poor OS. The research in treatment intensification and in identification of radioresistance biomarkers should therefore probably be focused on this particular subset of patients.

RESUMO

OBJECTIVE: Leukocytes are hypothesized to reflect the inflammatory tumor microenvironment. We aimed to validate their prognostic significance in a large cohort of patients treated with pre-operative radiation for locally advanced rectal cancer (RC). RESULTS: From 2004 to 2015, 257 RC patients with available biological data underwent a pre-operative radiotherapy, with a median age of 66 years. The median rectal EQD2 was 49.2Gy. Most of patients experienced concurrent chemotherapy (n = 245, 95.4%), mainly with 5-FU (83.3%). Clear surgical margins (i.e. complete resection) were achieved in 234 patients (91.1%). A complete (Mandard TRG1: n = 35, 13.6%) or almost complete pathological response (Mandard TRG2: n = 56, 21.8%) were achieved in 91 patients (35.4%). With a median follow-up of 46.1 months, 8 patients (3.1%) experienced local relapse, 38 (14.8%) experienced metastases and 45 (17.5%) died. Elevated pre-radiation neutrophil to lymphocyte ratio (NLR > 2.8) was identified as an independent predictive factor of increased local relapse, of decreased progression-free survival and overall survival in multivariate analysis. Elevated NLR was marginally associated with incomplete pathological response in multivariate analysis, suggesting a possible value as a biomarker of radio-sensitivity. CONCLUSIONS: Pre-radiation NLR is a simple and robust biomarker for risk stratification in locally advanced RC patients undergoing pre-operative radiotherapy, and might select the subpopulation eligible to treatment intensification or to neoadjuvant chemotherapy. MATERIAL AND METHODS: Clinical records from consecutive patients treated in a single institution between 2004 and 2015 with curative-intent radiotherapy were retrospectively analyzed. Classical prognosis factors of RC and peripheral immune markers based on lymphocytes and neutrophil counts were studied.

RESUMO

INTRODUCTION: Radiotherapy can diminish quality of life (QoL) for prostate cancer patients. Our objective was to evaluate the effect of radiotherapy on QoL in men aged 75 years or older treated with radiotherapy for a localized prostate cancer, and to identify predictors of reduced QoL. PATIENTS AND METHODS: We prospectively administered a battery of geriatric (MNA, GDS, Get up and Go Test, CIRS-G, ADL, IADL, MMSE), toxicity (IPSS; IIEF 5), and QoL (QLQ C30) screening tests in 100 elderly patients before and two months after prostate cancer radiotherapy (NCT 02876237). Patients ≥ 75 years undergoing radiotherapy with a curative intent for localized prostate cancer with or without androgen deprivation therapy (ADL) were eligible for study inclusion. Correlations between patient-assessed QoL and tumor characteristics, radiotherapy treatment or CGA parameters were sought using the Fisher or the Mann and Whitney tests. Changes in QoL parameters over time were analyzed using the Wilcoxon signed-rank test. RESULTS: At study entry, scores for IADL impairments were present in 51%, reduced autonomy in activities of daily living in 16%, cognitive impairment found in 20%, depression-related symptoms in 31%, and 66% of patients had significant co-morbidities. Eight percent were judged to be at risk of fall and 2% were found to be undernourished. Severely impaired (IPSS ≥ 20) urinary function was observed in 11.2% and 13.5% of patients before and two months after completion of radiotherapy respectively. Significantly decreased QoL (> 20 points) at two months after treatment was found in 13% of patients and a moderate but clinically relevant reduction (10 to 20 points) in 17% of patients. No tumor characteristic, treatment, or oncogeriatric parameter was predictive of reduced QoL following prostate cancer radiotherapy. CONCLUSION: Despite sometimes markedly diminished oncogeriatric parameters, prostate cancer radiotherapy was generally well tolerated in these elderly patients. We found no predictive factor to determine which patients would experience impaired quality of life following radiotherapy.

RESUMO

BACKGROUND: Despite screening campaigns, cervical cancers remain among the most prevalent malignancies and carry significant mortality, especially in developing countries. Most studies report outcomes of patients receiving the usual standard of care. It is possible that these selected patients may not correctly represent patients in a real-world setting, which may be a limitation in interpreting outcomes. This study was undertaken to identify prognostic factors, management strategies and outcomes of locally advanced cervical cancers (LACC) treated in daily clinical practice. METHODS: Medical files of all consecutive patients treated with curative intent for LACC in a French Cancer Care Center between 2004 and 2014 were reviewed retrospectively. RESULTS: Ninety-four patients were identified. Performance status was ≥ 2 in 10.6%. Median age at diagnosis was 63.0. Based on the International Federation of Gynecology and Obstetrics classification, tumours were classified as follows: 10.6% IB2, 22.3% IIA, 51.0% IIB, 4.3% IIIA and 11.7% IIIB. Pelvic lymph nodes were involved in 34.0% of cases. Radiotherapy was delivered for all patients. Radiotherapy technique was intensity modulated radiation therapy or volumetric modulated arc therapy in 39.4% of cases. A concurrent cisplatin chemotherapy was delivered in 68.1% of patients. Brachytherapy was performed in 77.7% of cases. The recommended standard care (concurrent chemoradiotherapy with at least five chemotherapy cycles during radiotherapy, followed by brachytherapy) was delivered in 43.6%. The median overall treatment time was 56 days. Complete tumour sterilisation was achieved in 55.2% of cases. Mean follow-up was 54.3 months. Local recurrence rate was 18.1%. Five-year overall survival was 61.9% (95% Confident Interval (CI) = 52.3-73.2) and five-year disease-specific survival was 68.5% (95% CI = 59.2-79.2). Poor performance status, lymph nodes metastasis and absence of concurrent chemotherapy were identified as poor prognostic factors in multivariate analysis. CONCLUSIONS: Less than 50% of patients received the standard care. Because LACC patients and disease are heterogeneous, treatment tailoring appears to be common in current clinical practice. However, guidelines for tailoring management are not currently available. More data about real-world settings are required in order to to optimise clinical trials' aims and designs, and make them translatable in daily clinical practice. TRIAL REGISTRATION: retrospectively registered.

RESUMO

BACKGROUND AND PURPOSE: There is paucity of data on the efficacy and toxicity of radiotherapy in rectal cancer (RC) elderly patients. The objective was to identify management strategies and resulting outcomes in RC patients ≥70 years undergoing radiotherapy. MATERIAL AND METHODS: A retrospective study included consecutive RC patients ≥70 years undergoing rectal radiotherapy. RESULTS: From 2004-2015, 340 RC patients underwent pre-operative (n = 238; 70%), post-operative (n = 41, 12%), or exclusive (n = 61, 18%) radiotherapy, with a median age of 78.5 years old (range: 70-96). Radiotherapy protocols were tailored, with 54 different radiotherapy programs (alteration of the total dose, and/or fractionation, and/or volume). Median follow-up was 27.1 months. Acute and late grade 3-4 radio-induced toxicities were reported in 3.5% and 0.9% of patients. Metastatic setting (OR = 6.60, CI95% 1.47-46.03, p = 0.02), exclusive radiotherapy (OR = 5.08, CI95% 1.48-18.21, p = 0.009), and intensity-modulated radiotherapy (OR = 6.42, CI95% 1.31-24.73, p = 0.01) were associated with grade ≥3 acute toxicities in univariate analysis. Exclusive radiotherapy (OR = 9.79, CI95% 2.49-43.18, p = 0.001) and intensity-modulated radiotherapy (OR = 12.62, CI95% 2.05-71.26, p = 0.003) were independent predictive factors of grade ≥3 acute toxicities in multivariate analysis. A complete pathological response was achieved in 12 out of 221 pre-operative patients (5.4%). Age, tumor stage, and surgery were independent predictive factors of survival in multivariate analysis. At end of follow-up, 7.1% of patients experienced local relapse. CONCLUSION: Radiotherapy for RC in elderly patients appeared safe and manageable, perhaps due to the tailoring of radiotherapy protocols. Tailored management resulted in acceptable rate of local tumor control.

RESUMO

BACKGROUND: How best to treat rising prostate-specific antigen (PSA) concentration after radical prostatectomy is an urgent clinical question. Salvage radiotherapy delays the need for more aggressive treatment such as long-term androgen suppression, but fewer than half of patients benefit from it. We aimed to establish the effect of adding short-term androgen suppression at the time of salvage radiotherapy on biochemical outcome and overall survival in men with rising PSA following radical prostatectomy. METHODS: This open-label, multicentre, phase 3, randomised controlled trial, was done in 43 French study centres. We enrolled men (aged ≥18 years) who had received previous treatment for a histologically confirmed adenocarcinoma of the prostate (but no previous androgen deprivation therapy or pelvic radiotherapy), and who had stage pT2, pT3, or pT4a (bladder neck involvement only) in patients who had rising PSA of 0·2 to less than 2·0 µg/L following radical prostatectomy, without evidence of clinical disease. Patients were randomly assigned (1:1) centrally via an interactive web response system to standard salvage radiotherapy (three-dimensional [3D] conformal radiotherapy or intensity modulated radiotherapy, of 66 Gy in 33 fractions 5 days a week for 7 weeks) or radiotherapy plus short-term androgen suppression using 10·8 mg goserelin by subcutaneous injection on the first day of irradiation and 3 months later. Randomisation was stratified using a permuted block method according to investigational site, radiotherapy modality, and prognosis. The primary endpoint was progression-free survival, analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT00423475. FINDINGS: Between Oct 19, 2006, and March 30, 2010, 743 patients were randomly assigned, 374 to radiotherapy alone and 369 to radiotherapy plus goserelin. Patients assigned to radiotherapy plus goserelin were significantly more likely than patients in the radiotherapy alone group to be free of biochemical progression or clinical progression at 5 years (80% [95% CI 75-84] vs 62% [57-67]; hazard ratio [HR] 0·50, 95% CI 0·38-0·66; p<0·0001). No additional late adverse events occurred in patients receiving short-term androgen suppression compared with those who received radiotherapy alone. The most frequently occuring acute adverse events related to goserelin were hot flushes, sweating, or both (30 [8%] of 366 patients had a grade 2 or worse event; 30 patients [8%] had hot flushes and five patients [1%] had sweating in the radiotherapy plus goserelin group vs none of 372 patients in the radiotherapy alone group). Three (8%) of 366 patients had grade 3 or worse hot flushes and one patient had grade 3 or worse sweating in the radiotherapy plus goserelin group versus none of 372 patients in the radiotherapy alone group. The most common late adverse events of grade 3 or worse were genitourinary events (29 [8%] in the radiotherapy alone group vs 26 [7%] in the radiotherapy plus goserelin group) and sexual disorders (20 [5%] vs 30 [8%]). No treatment-related deaths occurred. INTERPRETATION: Adding short-term androgen suppression to salvage radiotherapy benefits men who have had radical prostatectomy and whose PSA rises after a postsurgical period when it is undetectable. Radiotherapy combined with short-term androgen suppression could be considered as a reasonable option in this population.

RESUMO

No consensus exists regarding the role of radiotherapy in the management of gynecologic cancer in nonagenarian patients. We retrospectively reviewed the outcomes of 19 consecutive nonagenarian patients with gynecologic cancer (6 endometrial cancers, 6 cervical cancers, 4 vulvar cancers, and 3 vaginal cancers) who were treated with radiotherapy. Radiotherapy was performed mainly in a palliative setting (n = 12; 63.2%), with a median dose of 45 Gy (range, 6-76 Gy). Infrequent major acute or late toxicities were reported. Among 19 patients, 9 (47.4%) experienced tumor progression, 5 (26.3%) experienced complete response, 2 (10.5%) experienced stable disease and/or partial response. At last follow-up, 12 patients (63.2%) had died; most deaths (n = 9) occurred because of the cancer. These results suggest that radiotherapy is feasible in the treatment of nonagenarian patients with gynecologic cancer.

RESUMO

PURPOSE: Whereas post-radiation therapy overreactions (OR) represent a clinical and societal issue, there is still no consensual radiobiological endpoint to predict clinical radiosensitivity. Since 2003, skin biopsy specimens have been collected from patients treated by radiation therapy against different tumor localizations and showing a wide range of OR. Here, we aimed to establish quantitative links between radiobiological factors and OR severity grades that would be relevant to radioresistant and genetic hyperradiosensitive cases. METHODS AND MATERIALS: Immunofluorescence experiments were performed on a collection of skin fibroblasts from 12 radioresistant, 5 hyperradiosensitive, and 100 OR patients irradiated at 2 Gy. The numbers of micronuclei, γH2AX, and pATM foci that reflect different steps of DNA double-strand breaks (DSB) recognition and repair were assessed from 10 minutes to 24 hours after irradiation and plotted against the severity grades established by the Common Terminology Criteria for Adverse Events and the Radiation Therapy Oncology Group. RESULTS: OR patients did not necessarily show a gross DSB repair defect but a systematic delay in the nucleoshuttling of the ATM protein required for complete DSB recognition. Among the radiobiological factors, the maximal number of pATM foci provided the best discrimination among OR patients and a significant correlation with each OR severity grade, independently of tumor localization and of the early or late nature of reactions. CONCLUSIONS: Our results are consistent with a general classification of human radiosensitivity based on 3 groups: radioresistance (group I); moderate radiosensitivity caused by delay of nucleoshuttling of ATM, which includes OR patients (group II); and hyperradiosensitivity caused by a gross DSB repair defect, which includes fatal cases (group III).

RESUMO

BACKGROUND: We studied the efficacy and safety of cabazitaxel in unselected real-life patients. PATIENTS AND METHODS: We retrospectively investigated all patients with metastatic prostate cancer (mPC) treated with cabazitaxel 25 mg/m2 i.v. every 3 weeks combined with oral prednisolone (10 mg once daily) after first-line docetaxel chemotherapy. Study issues were to report patient characteristics and cabazitaxel data in terms of tolerance and efficacy. Overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method. All data were compared with TROPIC results. RESULTS: From 2011 to 2014, 41 patients received cabazitaxel; 15 patients (37%) had a performance status (PS) ≥2 versus 7% (p < 0.0001) in TROPIC, and 38 patients (93%) presented a Gleason score ≥7 at baseline (vs. 60%; p < 0.0001). All patients had metastatic disease at baseline. Previous therapies were radiotherapy in 17 patients (41 vs. 61%; p = 0.01) and surgery in 24 patients (59 vs. 52%; p = 0.4). The median number of cabazitaxel cycles was 5 (1-10) versus 6 (3-10) in TROPIC. Five patients completed 10 cycles of cabazitaxel (12%) versus 28% in TROPIC (p = 0.03). Toxicities were anemia (12 patients, 29%), diarrhea (9 patients, 22%), nausea (7 patients, 17%), pain (6 patients, 15%), sepsis (4 patients, 10%), neutropenia (3 patients, 7%) and urinary tract infection (1 patient, 2%). The tumor response rate was 19.5 versus 14.4% in TROPIC (nonsignificant). PFS was 4.5 months (95% CI 3.3-6.4) in our analysis and 2.8 months (95% CI 2.4-3.0) in TROPIC. OS was 12.1 months (95% CI 9.2 to not reached) and 15.1 months (95% CI 14.1-16.3), respectively. CONCLUSION: In our unselected mPC patients with poorer baseline clinical conditions and aggressive disease, cabazitaxel seems efficient and not more toxic than in the TROPIC study.

RESUMO

CONCLUSION: The present study demonstrates the feasibility of VMAT in association with platin or cetuximab in HNSCC and reports VMAT-related acute and late toxicities for the first time. OBJECTIVES: New radiotherapy techniques, such as Volumetric Modulated Arc Therapy (VMAT) were developed to lower RT-related toxicity. The aim of the present study was to investigate acute and late toxicities of head and neck squamous cell carcinoma (HNSCC) patients treated using VMAT. METHODS: This study investigated retrospectively all patients with HNSCC who received VMAT in curative intent. RESULTS: From 2010-2013, 150 patients were treated. Seventy-five patients (50%) received concurrent chemotherapy with VMAT, 51 patients (34%) received VMAT alone and 24 patients (16%) received concurrent cetuximab with VMAT. Mean delivered dose to planning target volume tumor (PTV T), high risk nodes (PTV HNR), low risk nodes (PTV LNR) and prophylactic nodes (PTV PN) were: 65.2 Gy, 62.9 Gy, 55.4 Gy, and 51.5 Gy, respectively. PTV mean coverages were higher than 96.5%. Most common grade 3/4 acute infield toxicities were mucosis (n = 28, 19%), dysphagia (n = 24, 16%), and dermatitis (n = 24, 16%). With a median follow-up of 16.0 months, most common late toxicities were dysphagia (n = 30, 20%), xerostomia (n = 28, 19%), larynx stiff (n = 17, 11%), and skin fibrosis (n = 14, 9%).

RESUMO

OBJECTIVE: The aim of this study was to report the first cases of salvage radiotherapy (RT) using the intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) targeted on choline positron emission tomography (PET) uptake in a local recurrent prostate cancer, after a radical prostatectomy. METHODS: Four patients received salvage irradiation for biochemical relapse that occurred after the initial radical prostatectomy. The relapse occurred from 10 months to 6 years with PSA levels ranging from 2.35 to 4.86 ng ml(-1). For each patient, an (18)F-choline PET-CT showed a focal choline uptake in prostatic fossa, with standardized uptake value calculated on the basis of predicted lean body mass (SUL) max of 3.3-6.8. No involved lymph node or distant metastases were diagnosed. IMRT doses were of 62.7 Gy (1.9 Gy/fraction, 33 fractions), with a SIB of 69.3 Gy (2.1 Gy/fraction, 33 fractions) to a PET-guided target volume. RESULTS: Acute toxicities were limited. We observed no gastrointestinal toxicity ≥grade 2 and only one grade 2 genitourinary toxicity. At 1-month follow-up evaluation, no complication and a decrease in PSA level (6.8-43.8% of the pre-therapeutic level) were reported. After 4 months, a decrease in PSA level was obtained for all the patients, ranging from 30% to 70%. At a median follow-up of 15 months, PSA level was controlled for all the patients, but one of them experienced a distant lymph node recurrence. CONCLUSION: Salvage irradiation to the prostate bed with SIB guided by PET-CT is feasible, with biological efficacy and no major acute toxicity. ADVANCES IN KNOWLEDGE: IMRT with PET-oriented SIB for salvage treatment of prostate cancer is possible, without major acute toxicity.

RESUMO

OBJECTIVE: The aim of our study was to evaluate emotional distress among women with breast cancer treated by radiotherapy, using a Visual Analogue Scale (an adaptation of the "Distress Thermometer" French version) associated with a Needs Scale with several items, in order to identify patients requiring psychological care. METHOD: Our sample is composed of 277 women treated for breast cancer with radiotherapy. Our psychological evaluation is made of a first enquiry using a visual analogue distress scale and complemented by a Needs Scale with several items. A grade above 3 on the visual analogue distress scale is a reliable indicator; a grade above 4 out of 20 leads us to propose the patient a consultation with a psychologist. RESULTS: Two hundred and sixty-four female patients with a mean age of 61 years are the object of the study. Among them, 59.2% of patients display a disarray of low intensity (psychological suffering graded between 0 and 2) whereas 40% show a grade equal or superior to 3, considered as pathological on a psychological side: 30% of the patients have a grade between 3 et 5 and less than 2% of the patients display a grade reaching 9 or 10. Concerning the Needs Scale, more than 80% of the patients show a total score below 10 out of 20 and we observe a positive correlation between the total score of the Needs Scale with several items and the Visual Analogue Distress Scale score. CONCLUSION: Our results highlight the difficulty for most of the patients to cope with emotional distress linked to their disease. We discuss the necessity to increase awareness among caregivers on this psychological distress, through the use of simple tools such as a Visual Analogue Scale associated with a Needs Scale, so as to provide a holistic care for women with breast cancer.

RESUMO

INTRODUCTION: There are only scarce data on the optimal management of patients who present with a bladder carcinoma and who are aged 90 years and older. PATIENTS AND METHODS: We retrospectively reviewed records from radiotherapy departments from two university hospitals, two private centers and one public center to identify patients who underwent radiotherapy for bladder cancer over the past decade and who were aged 90 years or older. From 2003 to 2013, 14 patients aged 90 years or older receiving RT for bladder malignant tumors were identified. RESULTS: Mean age was 92.7 years. Ten patients (71 %) had a general health status altered (PS 2-3) at the beginning of RT. A total of 14 RT courses were delivered, including six treatments (43 %) with curative intent and eight treatments (57 %) with palliative intent. Palliative intent mainly encompassed hemostatic RT (36 %). At last follow-up, two patients (14 %) experienced complete response, one patient (7 %) experienced partial response, three patients (21 %) had their disease stable, and three patients (21 %) experienced tumor progression, of whom two patients with the progression of symptoms. There was no reported high-grade acute local toxicity in 14 patients (100 %). One patient experienced delayed grade 2 toxicity with pain and lower urinary tract symptoms. At last follow-up, seven patients (50 %) were deceased. Cancer was the cause of death for five patients. CONCLUSION: Hypofractionated radiotherapy remains feasible for nonagenarians with bladder cancer. Further investigations including analysis of geriatric comorbidities and impact of treatments on quality of life should be conducted.

RESUMO

The ageing of French population imposes to radiotherapists the challenge to treat older patients and to adjust their treatment. Unthinkable 30 years ago, radiation therapy concerns nowadays patients aged more than 90 years old. Oncogeriatric scales have been improved those last years without necessarily making sure that the right treatment is given to the right patient: if oncogeriatric scales use influences the final therapeutic decision, it does not define new target volumes, new doses, or new fractionation protocols. Except for some organs, there is not, for the moment, any consensus concerning geriatric population adapted treatments. This makes any therapeutic decision difficult. The present review has for objective to realise a report of the studies about favorable and unfavorable effects of radiation therapy amongst aged (>70 years old) or very aged (>90years old) population.

RESUMO

BACKGROUND: During the ACCORD 12 randomized trial, an evaluation of the clinical tumor response was prospectively performed after neoadjuvant chemoradiotherapy. The correlations between clinical complete response and patient characteristics and treatment outcomes are reported. MATERIAL AND METHODS: Between 2005 and 2008 the Accord 12 trial accrued 598 patients with locally advanced rectal cancer and compared two different neoadjuvant chemoradiotherapies (Capox 50: capecitabine+oxaliplatin+50Gy vs Cap 45: capecitabine+45Gy). An evaluation of the clinical tumor response with rectoscopy and digital rectal examination was planned before surgery. A score to classify tumor response was used adapted from the RECIST definition: complete response: no visible or palpable tumor; partial response, stable and progressive disease. RESULTS: The clinical tumor response was evaluable in 201 patients. Score was: complete response: 8% (16 patients); partial response: 68% (137 patients); stable: 21%; progression: 3%. There was a trend toward more complete response in the Capox 50 group (9.3% vs 6.7% with Cap 45). In the whole cohort of 201 pts complete response was significantly more frequent in T2 tumors (28%; p=0.025); tumors <4cm in diameter (14%; p=0.017), less than half rectal circumference and with a normal CEA level. Clinical complete response observed in 16 patients was associated with more conservative treatment (p=0.008): 2 patients required an abdomino-perineal resection, 11 an anterior resection and 3 patients benefited from organ preservation (2 local excision, 1 "watch and wait". A complete response was associated with more ypT0 (73%; p<0.001); ypNO (92%); R0 circumferential margin (100%). CONCLUSION: These data support the hypothesis that a clinical complete response assessed using rectoscopy and digital rectal examination after neoadjuvant therapy may increase the chance of a sphincter or organ preservation in selected rectal cancers.

RESUMO

Rare cancers represent about a quarter of all cancers diagnosed in Europe, and their incidence is increasing. Meanwhile, scientific advances provide techniques, which become more and more sophisticated in the domain of radiotherapy. Treatment options for radiotherapy rare cancers are increasing, but are not yet evaluated. The question of the appropriateness of treatment by modern radiotherapy techniques in rare cancers remains. There are a lot of cases reported in the literature for treating rare cancers by modern technology. These techniques are often used when anatomical and dosimetric constraints do not achieve optimal treatment by surgery or standard radiotherapy. In contrast, standard radiotherapy techniques also provide good results in terms of overall survival and tolerance. They are also less expensive and less complex in terms of dosimetry. The establishment of specialized centers in rare cancers seems essential to evaluate the appropriateness of the use of modern techniques in these cases. Currently, data from the literature does not provide an answer to this question.

RESUMO

In France, there is an important interregional disparity concerning participation to cancer screening programs. The aim of this study was to assess oncologic screening practices in Loire, a French rural department, in women and in the elderly (over age 74 years). For this, two surveys were conducted. The first one was regarding screening for breast, cervical and colorectal cancer in women over age 18 years living in Loire. The second survey was regarding onco-geriatric screening through two questionnaires : one for the elderly and the other for general practitioner (GP) of the department, evaluating screening for breast, colorectal, prostate, cervical and lung cancer. One hundred sixty six women were included in the first investigation mean age of 47.6 years. Ninety three point six per cent were screening for breast cancer, 19% received Human Papilloma virus vaccine, 83.1% were screening by Papanicolau smear for cervical cancer and finally, 51.7% were screening for colorectal cancer, among the one entering screening program criteria. In the second survey, 44 patients and 28 GP were included. Thirty-eight point six per cent of patients over 74 years continue screening. Only 11.4% were reluctant to screening and in 80% because of anxiety du to the results. Among GP, 50 % continued screening on two major criteria : life expectancy and performans status. The present study shows heterogeneity of screening in this department both rural and working class and gives us a societo-medical photography.
