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: The present study aimed to assess the correlation between dose to pelvic lymph nodes and to point B with tandem-ring (TR) applicators for intra-cavitary brachytherapy treatment of locally advanced cervical cancer. Material and methods: Cervical cancer patients treated at brachytherapy department of Lucien Neuwirth Cancer Center, from 2015 to 2018, were included. Target delineation was performed in compliance with GEC-ESTRO guidelines. Revised American Brachytherapy Society (ABS) point A was determined (ARN (right) and ALN (left)) as well as Manchester point B. Prescription dose was 25-35 Gy in 5 fractions. Pelvic lymph nodes were delineated, then dose to points A and B, and dose-volume histogram (DVH) parameters of delineated lymph nodes were extracted. Significant relationships or correlations between lymph nodes reference points, dosage to points B, and their DVH parameters were investigated. Results: The mean dose and mean percentage of the prescription dose to the left and right points B were 4.6 ±0.18 Gy and 82.08 ±0.72%, respectively. Pearson correlation coefficient R = 0.81 (p-value = 0.00) between dose to ARN and ALN points and prescription dose was obtained. Negative correlation between CTVHR volume and difference between French and ABS prescription points was found. Conclusions: Dose to point B can be a moderate surrogate for maximum, minimum, and median dose to the internal iliac and presacral lymph node, but cannot be for maximum dose to the obturator lymph node. Points B cannot be a reliable substitute for common and external iliac chains.

RESUMO

BACKGROUND: This retrospective study was conducted to: (1) provide more modern data on real-life local management of metastatic rectal cancer; (2) compare therapeutic strategies; and (3) identify prognostic factors of local failure, overall survival and progression-free survival. METHODS: Data about efficacy and acute toxicity were collected. Patients were diagnosed with metastatic rectal cancer between 2004 and 2015, and were treated at least with radiotherapy. Local failure, overall survival and progression-free survival were correlated with patient, tumour and treatment characteristics using univariate and multivariate analyses. RESULTS: Data of 148 consecutive patients with metastatic rectal cancer were analysed. Median follow-up was 19 months. Median overall survival was 16 months. All patients received local radiotherapy, with a median equivalent 2 Gy per fraction dose of 47.7 Gy. Rectal surgery was performed in 97 patients (65.6%). The majority of patients (86/97, 88.7%) received pre-operative chemoradiation. In multivariate analysis, rectal surgery was found to be the only independent predictor of increased overall survival (24.6 vs 7.1 months, p <0.001). Of the patients undergoing surgical treatment, 22.8% presented with significant complications that required a delay of systemic treatment. Grade 3-4 acute radiation therapy-related toxicities were observed in 6.1% of patients, mainly gastrointestinal toxicities (5.4%). CONCLUSION: Rectal surgery was a key predictive factor of increased progression-free survival and overall survival in patients receiving at least local radiotherapy. In our series of real-life patients, local surgery and radiation seemed as well tolerated as reported in selected phase III non-metastatic rectal cancer patients. These data suggested that local management could be beneficial for metastatic rectal cancer patients.

RESUMO

OBJECTIVES: We aimed at describing and assessing the quality of reporting in all published prospective trials about radiosurgery (SRS) and stereotactic body radiotherapy (SBRT). METHODS: The Medline database was searched for. The reporting of study design, patients' and radiotherapy characteristics, previous and concurrent cancer treatments, acute and late toxicities and assessment of quality of life were collected. RESULTS: 114 articles - published between 1989 and 2019 - were analysed. 21 trials were randomised (18.4%). Randomisation information was unavailable in 59.6% of the publications. Data about randomisation, ITT analysis and whether the study was multicentre or not, had been significantly less reported during the 2010-2019 publication period than before (respectively 29.4% vs 57.4% (p < 0.001), 20.6% vs 57.4% (p < 0.001), 48.5% vs 68.1% (p < 0.001). 89.5% of the articles reported the number of included patients. Information about radiation total dose was available in 86% of cases and dose per fraction in 78.1%. Regarding the method of dose prescription, the prescription isodose was the most reported information (58.8%). The reporting of radiotherapy characteristics did not improve during the 2010 s-2019s. Acute and late high-grade toxicity was reported in 37.7 and 30.7%, respectively. Their reporting decreased in recent period, especially for all-grade late toxicities (p = 0.044). CONCLUSION: It seems necessary to meet stricter specifications to improve the quality of reporting. ADVANCES IN KNOWLEDGE: Our work results in one of the rare analyses of radiosurgery and SBRT publications. Literature must include necessary information to first, ensure treatments can be compared and reproduced and secondly, to permit to decide on new standards of care.

RESUMO

BACKGROUND: In most clinical trials, gold fiducial markers are implanted in the prostate to tune the table position before each radiation beam. Yet, it is unclear if a cone-beam computed tomography (CBCT) should be performed before each beam to monitor a possible variation of the organs at risk (OARs) fullness, especially in case of recto-prostatic spacer implantation. The present study aimed at assessing the inter- and intra-fraction movements of prostate, bladder and rectum in patients implanted with a hyaluronic acid spacer and undergoing prostate stereotactic body radiotherapy (SBRT). METHODS: Data about consecutive patients undergoing prostate SBRT were prospectively collected between 2015 and 2019. Inter-and intra-fraction prostate displacements and volume variation of organs at risk (OARs) were assessed with CBCTs. RESULTS: Eight patients were included. They underwent prostate SBRT (37.5Gy, 5 fractions of 7.5Gy) guided by prostate gold fiducial markers. Inter-fraction variation of the bladder volume was insignificant. Intra-fraction mean increase of the bladder volume was modest (29 cc) but significant (p < 0.001). Both inter- and intra-fraction variations of the rectum volume were insignificant but for one patient. He had no rectal toxicity. The magnitude of table displacement necessary to match the prostate gold fiducial marker frequently exceeded the CTV/PTV margins (0.4 cm) before the first (35%) and the second arc (15%). Inter- and intra-fraction bladder and rectum volume variations did not correlate with prostate displacement. CONCLUSION: Major prostate position variations were reported. In-room kV fiducial imaging before each arc seems mandatory. Intra-fraction imaging of the OARs appears unnecessary. We suggest that only one CBCT is needed before the first arc.

RESUMO

BACKGROUND: Testicular Germ Cell Tumors (TGCTs) represent the most frequent malignant tumour among young male adults. Orchiectomy alone cure 80% of stage I. Standard options after orchiectomy include radiotherapy (RT), chemotherapy (CT) by 1 cycle of carboplatin AUC 7 or active surveillance (SV) for seminomatous GCTs (SGCT) and retroperitoneal lymphadenectomy (RPLND), CT by 1 or 2 cycles of Bleomycine Etoposide Cisplatine (BEP) or active surveillance for nonseminomatous GCTs (NSGCT). Adjuvant treatments decrease the relapse rate after orchiectomy with substantial toxicities without any benefit on overall survival. Recent guidelines accorded utmost importance on SV rather than adjuvants strategies. The main objective of this study was to describe our current practice over the 10 past years in regard of these recommendations. METHODS: Data of 50 patients with stage I GCT treated in our institute were collected between 2006 and 2016. Demographic and anatomopathologic data were reported. Clinical practice in our center was analyzed during two periods [2006-2011] and [2012-2016] according to the European Association of Urology Guidelines in 2011. RESULTS: Patient's median age was 35.3 years. The analysis of clinical practice during the last 10 years showed that in SGCT, main treatment was RT than SV and CT. This option declined over the years (89% between 2006-2010 versus 53% between 2011-2016) whereas SV was more often employed (27% between 2011-2016 versus none between 2006-2010). Surveillance was used for 64% of NSGCT. CONCLUSIONS: In our center, RT was less used over the years for the benefit of SV which is recommended by guidelines.

RESUMO

Leptomeningeal metastasis (LM) in solid tumors are rare, even more in renal cell carcinoma (RCC). To date there is a lack of consensual treatment modalities of leptomeningeal metastasis. Furthermore, with the improvement of outcomes and more effective systemic targeted therapies, the management of leptomeningeal metastasis becomes a real challenge. We here report two cases of RCC with leptomeningeal metastasis at initial diagnosis. Both patients had concurrent adjacent skull bone metastasis. Therapeutic management of both patients consisted in surgical resection, followed by radiotherapy in one case. Systemic treatment was delayed according to current recommendations for the management of metastatic RCC. The aim of this work is to report the therapeutic approach and related outcomes and also provide a review of the currently available literature on leptomeningeal disease in renal cell carcinoma. Indeed, local treatment with curative outcome of meningeal location in RCC should be performed specially in LM at initial diagnosis.

RESUMO

OBJECTIVES: The aim of this study was to identify and compare prognostic factors, management strategies, and outcomes of very locally advanced cervical cancer (CC) (i.e., stage IVA) and metastatic CC (i.e., stage IVB). METHOD: A retrospective review was conducted based on all consecutive patients treatedfor stage IV CC in a comprehensive cancer care centre between 2004 and 2017. RESULTS: Sixty-eight patients were included. Performance status (PS) was ≥2 for 35.9%. Median age at diagnosis was 60.5. There were 24 stage IVA CC (35.3%) and 44 stage IVB CC (64.7%). Seventeen patients with stage IVB CC had only para-aortic lymph node metastases (38.6%), 13 had only distant metastases (29.5%), and 14 had both (31.8%). Patients with stage IVA CC experienced a radiotherapy with curative intent (n = 14, 58.3%) +/- concomitant chemotherapy, or a palliative treatment (n = 10, 41.7%). Twenty-three patients with stage IVB CC received a prior chemotherapy (52.3%), 11 a primary concomitant chemoradiation (25%), and 10 a palliative treatment (22.7%). The mean follow-up was 18.0 months. The 5-year overall survival was 5.1% for stage IVA (95% CI = 0.7-33.9), and 10.5% for stage IVB (95% CI = 3.7-29.7). In multivariate analysis, PS >1 was identified as a poor prognostic factor of disease-specific survival for stage IVA CC. PS >1 and pelvic lymph node involvement were identified as poor prognostic factors of overall survival and disease-specific survival for stage IVB CC. CONCLUSIONS: In daily clinical practice, outcomes of stages IV CC are poor. Treatment of advanced and metastatic CC remains challenging. New management strategies are needed, as well as efficient preventive strategies.

RESUMO

Brachytherapy has the unique characteristic of being able to deliver high doses to a very localized volume, and remains one of the radiotherapy techniques that has an unparalleled therapeutic index. However, its use has been declining in the past years. Globally, only 55 to 88 % of patients with locally advanced cervical cancer benefit from utero-vaginal brachytherapy, despite the fact that it is proven to enhance both progression-free and overall survival. A decline in the use of low dose rate brachytherapy has likewise been described in the treatment of low-risk and favorable intermediate-risk prostate cancers. Several factors could explain this. First, the radiation oncologists who have the proficiency to perform brachytherapy seems to be inadequate, as it is a technique that requires training and expertise for optimal applications. In many cancer care centers, the caseload is insufficient to provide this experience. Second, the increasing use of technically advanced external beam radiation therapy, such as intensity modulated radiation therapy, offers an easier substitute with more lucrative benefits, resulting in decreased utilization of brachytherapy. However, when brachytherapy is not delivered, a poorer survival rate is reported in locally advanced cervical cancer, and is suggested in intermediate and high-risk prostate cancer. The increasing level of evidence of treatment with brachytherapy necessitates an improvement in its accessibility by having more radiation oncologists as well as cancer centers equipped to perform the procedure.

RESUMO

Background: Phase II trials are designed to assess the efficacy/toxicity ratio of experimental treatments and select those worth being tested in phase III trials. Although crucial limitations were identified when concurrent chemoradiation (cCRT) phase III trials characteristics were assessed, features of cCRT phase II trials have never been reported. The objective was to describe features of all cCRT phase II trials. Methods and material: 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 II as topic', 'chemoradiotherapy'. Results: Four hundred and fifty-eight cCRT phase II trials were identified. They were mainly multicenter (51.5%), single arm studies (77.7%) published after 2011 (55.0%). The median number of included patients was 52. Primary endpoints were mainly response rate (20.5%), pathological complete response (14.4%) and overall survival (12.6%). The primary endpoint was not defined in 22% of studies. Tumors were mostly lung (23.1%), head and neck (20.3%), colorectal (16.6%) and esophagogastric cancer (14.6%) treated at a locally advanced setting (81.7%). 55.2% of trials used 3D-conformal radiotherapy and 9.1% intensity-modulated radiotherapy, mainly with normo-fractionation (82.0% of the 573 arms with radiotherapy). Radiation technique was not reported in 19.9% of studies. Associated anticancer drugs (563 arms) were mainly conventional chemotherapies (559 arms): cisplatin (46.2%) and 5-fluorouracil (28.3%). Non cytotoxic agents (targeted therapies, immunotherapies) were tested in 97 arms (17%). With a median follow-up of 31 months, acute grades 3-5 were reported in 98.5% of studies and late toxicities in 44.5%. Follow-up was not reported in 17% of studies. Conclusions: cCRT phase II trials featured severe limitations, with outdated radiation techniques, insufficient reporting of crucial data and a small number of included patients. This certainly limited the impact of conclusions and hindered the development of successful phase III trials.

RESUMO

PURPOSE: To assess the safety of the association of radiotherapy (RT) and systemic treatments for patients with metastatic malignant melanoma (mMM). METHODS: A retrospective analysis included consecutive patients treated with palliative RT, and at least one line of systemic therapy for mMM between 2001 and 2016. Treatments were defined as sequential or concomitant when RT and the systemic drug were administered, respectively, at more or less than five half-lives from each other. RESULTS: 92 patients were included. They had 110 palliative RT treatments. RT was delivered with a "conventional" chemotherapy (mainly fotemustine and/or dacarbazine) and a "modern" systemic therapy (BRAF inhibitors, association of BRAF and MEK inhibitors, immunotherapy), respectively, in 88 (80%) and 22 (20%) cases. Systemic treatments and RT were mainly concurrently performed (n = 61, 55.5%). Regarding acute grade ≥ 3 toxicity, no difference was reported between sequential and concomitant groups either in the whole cohort (p = 1) or in the subgroup of patients receiving "modern" systemic therapies (p = 1). Acute and late grade ≥ 3 toxicities only occurred with vemurafenib. BRAF inhibitors and RT produced more severe infield adverse events than other associations (p = 0.001) with two deaths. CONCLUSION: In our series, compared to sequential administration, concomitant association of systemic anticancer drugs and palliative RT did not increase toxicity in mMM patients. BRAF inhibitors and RT produced severe infield toxicities. Prospective studies are needed to better characterize the toxicity of each association.

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

OBJECTIVE: To describe the current state of knowledge concerning the quality of reporting in phase II clinical trials in oncology and to describe the various methods published allowing this quality evaluation. METHODS: databases including MEDLINE and COCHRANE were searched. Reviews and meta-analyses analyzing the quality of the reporting of phase II trials in oncology were included. Descriptive analysis of the results was performed. RESULTS: Thirteen publications were retained. Only 2 publications adopted a systematic approach of evaluation of the quality of reporting by overall scores. The Key Methodological Score (KMS), proposed by Grellety et al., gathering 3 items, seemed adapted for such an evaluation. A score of 3/3 was found in 16.1% of the 156 phase II trials analysed by this score. The other reviews used a qualitative analysis to evaluate the reporting, via an analysis of a single criterion, generally the statistical plan of the study. This item was considered as having been correctly reported in less than 50% of the analysed articles. CONCLUSION: The quality of reporting in phase II trials in oncology is a field that has been investigated very little (13 publications). When it is studied, the estimated level of quality is not satisfactory, whatever the method employed. The use of an overall score of evaluation is a path which should be pursued, in order to get reliable results. It also seems necessary to propose strong recommendations, which would create a consensus for the methodology and the reporting of these studies.

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: Phase II clinical trials are a cornerstone of the development in experimental treatments They work as a "filter" for phase III trials confirmation. Surprisingly the attrition ratio in Phase III trials in oncology is significantly higher than in any other medical specialty. This suggests phase II trials in oncology fail to achieve their goal. Objective The present study aims at estimating the quality of reporting in published oncology phase II clinical trials. DATA SOURCES: A literature review was conducted among all phase II and phase II/III clinical trials published during a 5-year period (2010-2015). STUDY ELIGIBILITY CRITERIA: All articles electronically published by three randomly-selected oncology journals with Impact-Factors>4 were included: Journal of Clinical Oncology, Annals of Oncology and British Journal of Cancer. INTERVENTION: Quality of reporting was assessed using the Key Methodological Score. RESULTS: 557 articles were included. 315 trials were single-arm studies (56.6%), 193 (34.6%) were randomized and 49 (8.8%) were non-randomized multiple-arm studies. The Methodological Score was equal to 0 (lowest level), 1, 2, 3 (highest level) respectively for 22 (3.9%), 119 (21.4%), 270 (48.5%) and 146 (26.2%) articles. The primary end point is almost systematically reported (90.5%), while sample size calculation is missing in 66% of the articles. 3 variables were independently associated with reporting of a high standard: presence of statistical design (p-value <0.001), multicenter trial (p-value = 0.012), per-protocol analysis (p-value <0.001). LIMITATIONS: Screening was mainly performed by a sole author. The Key Methodological Score was based on only 3 items, making grey zones difficult to translate. CONCLUSIONS & IMPLICATIONS OF KEY FINDINGS: This literature review highlights the existence of gaps concerning the quality of reporting. It therefore raised the question of the suitability of the methodology as well as the quality of these trials, reporting being incomplete in the corresponding articles.

RESUMO

BACKGROUND: Cancer patients tend to use more and more complementary or alternative medicine concomitantly to radiotherapy. A large part of these patients have recourse to Mind and Body practice, mainly with biofield healers or magnetizers, without any level of evidence. The aim of the present study was to report epidemiologic data on biofield healers in radiation therapy patients, and to assess the possible objective and subjective benefits. MATERIALS AND METHODS: A retrospective study was conducted in a French cancer institute. All consecutive breast or prostate cancer patients undergoing a curative radiotherapy during 2015 were screened (n = 806). Healer consultation procedure, frequency, and remuneration were collected. Patient's self-evaluation of healer's impact on treatment tolerance was reported. Tolerance (fatigue, pain) was assessed through visual analogic scale (0 to 10). Analgesic consumption was evaluated. Toxicities were described according to NTCAEv4.0. RESULTS: 500 patients were included (350 women and 150 men). A total of 256 patients (51.2%) consulted a healer during their radiation treatment, with a majority of women (58%, p < 0.01). Most of patients had weekly (n = 209, 41.8%) or daily (n = 84, 16.8%) appointments with their healer. Regarding the self-reported tolerance, > 80% of the patients described a "good" or "very good" impact of the healer on their treatment. Healers were mainly voluntary (75.8%). Regarding the clinical efficacy, no difference was observed in prostate and in breast cancer patients (toxicity, antalgic consumption, pain). CONCLUSIONS: This study reveals that the majority of patients treated by radiotherapy consults a healer and reports a benefit on subjective tolerance, without objective tolerance amelioration.

RESUMO

Immunotherapy is on the roll. After revolutionary effects in melanoma, immunotherapy is invading other locations. If current treatments, chemotherapies or targeted therapies block one pathway, immunotherapy should be understood as the activation of a whole system. Indeed, oncogenesis process is defined as an escape of the immune system and the stimulation of this system can block the carcinogenic process. The aim of the present review is to describe the place of immunotherapy in the treatment of solid cancers.

RESUMO

In the past few years, metastatic renal cell carcinoma prognosis was improved by the development of molecular targeted therapies (TTs). At the metastatic stage, the tolerance to treatment is a major concern, not only because of the challenge of the efficacy/toxicity ratio improvement but also because of the importance of an optimal adherence to oral treatments. The present case series relates the issues of dealing with uncommon and sometimes never described side effects of sunitinib and sorafenib. The first case report deals with grade 3 vomiting during hemodialysis with concurrent administration of sunitinib. The second case is an iterative gout attack induced by sunitinib. The third case presents a grade 3 scalp dysesthesia with sorafenib. The fourth case includes an astonishing efficacy of metronomic (ie, low doses during a long period of time) bevacizumab in monotherapy. Multidisciplinary management and systematic reporting of unexpected efficacies and toxicities are needed to better understand TTs real therapeutic index. Although TTs revolutionized metastatic renal cell cancer prognosis, they also brought about previously unknown side effects. Identification and management of these off-target effects may be tricky, and therefore, comedication must be wisely chosen. As the physiopathology of these side effects is still unclear, multidisciplinary management and systematic reporting of toxicities are essential.
