RESUMO

For many years, adjuvant chemoradiotherapy remained essential in the therapeutic management of gastric and pancreatic adenocarcinomas. For these tumours, surgical excision, the only hope of offering the patient prolonged survival, is only possible in 20% of cases. The median survival of operated patients is only 12 to 20 months due to the frequency of locoregional and/or metastatic recurrences. For stomach cancers, adjuvant chemoradiotherapy is justified by the results of the phase III trial Intergroup 0116 published by MacDonald et al. The gain in survival was at the cost of significant toxicity. This treatment was supplanted in the early 2000s by perioperative chemotherapy. Currently, neoadjuvant chemoradiotherapy clinical studies are ongoing with the aim of improving treatments observance and tolerance. For pancreatic cancers, the role of adjuvant chemoradiotherapy has long been discussed because of trials with contradictory results. Neoadjuvant radiotherapy has many advantages in terms of efficacy and tolerance. It increases the chances of subsequent complete tumour resection. Several prospective trials are currently ongoing to clarify its place in the therapeutic arsenal.

RESUMO

Hypoxia promotes tumour aggressiveness and resistance of cancers to oncological treatment. The identification of cancer cell internalizing antigens for drug targeting to the hypoxic tumour niche remains a challenge of high clinical relevance. Here we show that hypoxia down-regulates the surface proteome at the global level and, more specifically, membrane proteome internalization. We find that hypoxic down-regulation of constitutive endocytosis is HIF-independent, and involves caveolin-1-mediated inhibition of dynamin-dependent, membrane raft endocytosis. Caveolin-1 overexpression inhibits protein internalization, suggesting a general negative regulatory role of caveolin-1 in endocytosis. In contrast to this global inhibitory effect, we identify several proteins that can override caveolin-1 negative regulation, exhibiting increased internalization at hypoxia. We demonstrate antibody-mediated cytotoxin delivery and killing specifically of hypoxic cells through one of these proteins, carbonic anhydrase IX. Our data reveal that caveolin-1 modulates cell-surface proteome turnover at hypoxia with potential implications for specific targeting of the hypoxic tumour microenvironment.

RESUMO

OBJECTIVES: To date, no studies have yet assessed the characteristics of non-HCV patients with low level of cryoglobulin (≤0.05 g/L). The aims of the current study were thus to: 1) determine the prevalence of cryoglobulin ≤0.05 g/L in patients with non-HCV cryoglobulin; and 2) compare clinical features and long term outcome, including organ complications and mortality rate, between non-HCV patients with cryoglobulin level ≤0.05 g/L and those exhibiting cryoglobulin level >0.05 g/L. METHODS: Among 6379 cryoglobulin testing, cryoglobulin was detected in 618 patients (9.69% of cases); of these 618 patients, 453 non-HCV patients were included in the study. The medical records of these patients were reviewed. RESULTS: Of the 453 non-HCV cryoglobulin-positive patients, 265 (58.6%) exhibited cryoglobulin level ≤0.05 g/L. We showed that patients with cryoglobulin level ≤0.05 g/L had: 1) less commonly: palpable purpura (p<0.001), digital ulcers (p=0.006), peripheral neurologic involvement (p=0.03) and renal impairment (p=0.03); and 2) lower median values of ESR (p<0.001) and C-reactive protein (p=0.001). The patients with cryoglobulin level ≤0.05 g/L less often experienced infections (p=0.04) and hematological malignancies (p=0.01); both groups did not differ regarding prevalence of connective tissue diseases and solid tumors. Mortality rate was as high as 13.6% in patients with cryoglobulin level ≤0.05 g/L; death was mainly due to: solid tumors (16.6%), cardiovascular complications (13.8%), hematological malignancies (11.1%), infections (8.3%), pulmonary/renal complications of cryoglobulin (8.3%) and connective tissue diseases (8.3%). CONCLUSION: Our study shows a high prevalence of cryoglobulin level ≤0.05 g/L in clinical practice. Our findings further underscore that non-HCV cryoglobulin level ≤0.05 g/L may be responsible for severe renal and neurological complications, leading to high morbidity and mortality in these patients. Thus, our data suggest that both appropriate therapy and close follow-up may be required to improve such patients' outcome.

RESUMO

BACKGROUND: The primary objective was to evaluate correlations linking anatomical to functional outcomes after endoscopically assisted repair of acute acromioclavicular joint dislocation (ACJD). HYPOTHESIS: Combined acromioclavicular and coracoclavicular stabilisation improves radiological outcomes compared to coracoclavicular stabilisation alone. MATERIAL AND METHODS: A prospective multicentre study was performed. Clinical outcome measures were pain intensity on a visual analogue scale (VAS), subjective functional impairment (QuickDASH score), and Constant's score. Anatomical outcomes were assessed on standard radiographs (anteroposterior view of the acromioclavicular girdle and bilateral axillary views) obtained preoperatively and postoperatively and on postoperative dynamic radiographs taken as described by Tauber et al. RESULTS: Of 116 patients with acute ACJD included in the study, 48% had type III, 30% type IV, and 22% type V ACJD according to the Rockwood classification. Coracoclavicular stabilisation was achieved using a double endobutton in 93% of patients, and concomitant acromioclavicular stabilisation was performed in 50% of patients. The objective functional outcome was good, with an unweighted Constant's score ≥ 85/100 and a subjective QuickDASH functional disability score ≤ 10 in 75% of patients. The radiographic analysis showed significant improvements from the preoperative to the 1-year postoperative values in the vertical plane (decrease in the coracoclavicular ratio from 214 to 128%, p=10(-6)) and in the horizontal plane (decrease in posterior displacement from 4 to 0mm, p=5×10(-5)). The anatomical outcome correlated significantly with the functional outcome (absolute R value=0.19 and p=0.045). We found no statistically significant differences across the various types of constructs used. Intra-operative control of the acromioclavicular joint did not improve the result. Implantation of a biological graft significantly improved both the anatomical outcome in the vertical plane (p=0.04) and acromioclavicular stabilisation in the horizontal plane (p=0.02). The coracoclavicular ratio on the anteroposterior radiograph was adversely affected by a longer time from injury to surgery (p=0.02) and by a higher body mass index (BMI) (p=0.006). High BMI also had a negative effect on the difference in the distance separating the anterior edge of the acromion from the anterior edge of the clavicle between the injured and uninjured sides, as assessed on the axillary views (p=0.009). CONCLUSION: This study demonstrates that acute ACJD requires stabilisation in both planes, i.e., at the coracoclavicular junction and at the acromioclavicular joint. Coracoclavicular stabilisation alone is not sufficient, regardless of the type of implant used. Implantation of a biological graft should be considered when the time from injury to surgery is longer than 10days. The weight of the upper limb should be taken into account, with 6weeks of immobilisation to unload the construct in patients who have high BMI values. LEVEL OF EVIDENCE: II, prospective non-randomised comparative study.

RESUMO

INTRODUCTION: Treatment of chronic acromioclavicular joint dislocation (ACJD) remains a poorly known and controversial subject. Given the many surgical options, it is not always easy to determine which steps are indispensable. METHODS: This article reports a multicenter prospective study. The clinical and radiological follow-up involved a comparative analysis of the preoperative and postoperative data at 1 year, including pain (visual analogue scale), subjective functional incapacity (QuickDASH), and the objective Constant score, as well as a comparative analysis of vertical and horizontal movements measured on simple x-rays. RESULTS: Based on a series of 140 operated ACJDs, we included 24 chronic ACJDs. The mean time to surgery was 46 weeks (range, 1 month to 4 years). The patients' mean age was 41 years, with a majority of males (75%), 72% of whom participated in recreational sports. Professionally, 40% of the subjects had jobs involving manual labor. We noted 40% grade III, 24% grade IV, and 36% grade V injury according to the Rockwood classification. In 92% of cases, coracoclavicular stabilization was provided by a double button implant, reinforced with a biological graft in 88% of the cases. In 29%, millimeters to centimeters of the distal clavicle were resected and acromioclavicular stabilization was associated in 54%. We observed complications in 33% of the cases. At 1 year postoperative, 21 patients underwent clinical and radiological follow-up (87.5%). Only 35% of the patients were satisfied or very satisfied, whereas 100% of them would recommend the operation. Full-time work was resumed in 91% of the cases and all sports could be resumed in 86%. The pre- and postoperative values at 1 year changed as follows: the mean Constant score improved from 61 to 87 (p=0.00002); the subjective QuickDASH score decreased from 41 to 9 (p=0.00002); and radiologically significant reduction of the initial displacement was observed in the vertical plane (p<10(-3)) and the horizontal plane (p=0.022). CONCLUSION: In this study, the favorable prognostic factors found were: time to surgery less than 3 months (p=0.02), associated acromioclavicular stabilization, and postoperative immobilization with a sling extended to 6 weeks. However, resection of the distal clavicle did not influence the final result. LEVEL OF PROOF: Level II prospective non-randomized comparative study.

RESUMO

OBJECTIVES: To study the adnexectomy by laparoendoscopic single-site surgery with conventional laparoscopic instruments, we standardised the technique of salpingo-oophorectomy. PATIENTS AND METHODS: In this prospective study, all patients with adnexectomies from June 2010 to January 2014 were included. Laparoendoscopic single-site adnexectomy with conventional instruments is described step by step in order to make it available for the majority of gynecologic surgeons. Laparoconversions and complications are also noted. RESULTS: We realized 42 bilateral salpingo-oophorectomies, 16 single salpingo-oophorectomy. The average operative time was 45min (15-120) with negligible blood losses. There were no laparoconversions and very few complications. After 15-20 adnexectomies, the procedure took less and less time. DISCUSSION AND CONCLUSION: Adnexectomy by laparoendoscopic single-site surgery procedure with conventional laparoscopic instruments is easily reproducible with standardized steps and has many advantages.

RESUMO

Indications for adjuvant radiotherapy in breast cancer are defined from the clinical data and the pathological extent of disease in the surgical specimen. Neoadjuvant chemotherapy could modify the pathological characteristics of the tumour, inducing a pathologic complete response in 15 to 50% of cases, challenging the classical indications of adjuvant radiotherapy. The benefit of adjuvant radiotherapy after neoadjuvant chemotherapy was not prospectively evaluated. Nonetheless, from retrospective series, some recommendations with a low level of proof could be given: (i) after lumpectomy, radiotherapy of the mammary gland must be performed even in case of pathologic complete response; (ii) after mastectomy, postoperative radiotherapy is recommended in case of cT3-T4, cN1-3 (clinical or radiological) or pathologically involved nodes; (iii) irradiation of the lymph nodes areas is more questionable, but could be also proposed in case of cN1 or pN1. These recommendations are in accordance with those recently published by the National Cancer Institute and the French National Cancer Institute.

RESUMO

OBJECTIVE: To analyze patients' views with regards to local consultations given by specialists in urology and to an offer of pre- and postoperative visits in the local general hospital with surgical interventions taking place at the university hospital. MATERIALS AND METHODS: An opinion survey by mail questionnaire was carried out in all 473 patients who had had a consultation with a specialist in two local general hospitals between November 2009 and April 2010. RESULTS: Response rate was 74%. Mean patient age was 65.5 ± 12 years [range, 20-90]. The reason for the consultation was cancer-related in 31.2% of patients. The majority (89%) made the journey to hospital under their own steam and would have had to travel a 4 times greater distance if the consultation with the specialist had taken place at the university hospital. Overall, 54.6% of patients were willing to travel 20 km further to see a specialist and 76.5% were willing to travel 20 km further for a surgical intervention. Virtually all of the patients (>99%) saw benefits to local consultations given by specialists. The offer of a consultation at the general hospital and intervention at the university hospital met with the approval of 60.8% patients and 56.3% had already experimented this offer. CONCLUSION: Local consultations by specialists might be an answer to demographic issues in France, that is, to the small number of urologists practicing in general hospitals.

RESUMO

BACKGROUND: The aims of the present study were to determine both clinical manifestations and outcome of anti-PL7 patients with antisynthetase syndrome (ASS). METHODS: The medical records of 15 consecutive anti-PL7 patients with biopsy proven ASS were retrospectively analyzed without prior selection. RESULTS: Anti-PL7 patients exhibited polymyositis (n=14) and dermatomyositis (n=1); extra-pulmonary manifestations of ASS included: Raynaud's phenomenon (40%), mechanic's hands (33.3%), joint impairment (26.7%), pericardial effusion (20%) and esophageal/gastrointestinal involvement (20%). The outcome of myositis was as follows: remission/improvement (91.7%) and deterioration (8.3%). Fourteen patients (93.3%) experienced interstitial lung disease (ILD). ILD preceded ASS diagnosis (n=5), was identified concomitantly with ASS (n=8) and occurred after ASS diagnosis (n=1). Patients could be divided into 3 groups according to their presenting lung manifestations: acute onset of lung disease (n=1), progressive onset of lung signs (n=11) and asymptomatic patients exhibiting abnormalities consistent with ILD on PFT and HRCT-scan (n=2). No patient had resolution of ILD, whereas 64.3% and 35.7% experienced improvement and deterioration of ILD, respectively. ILD resulted in respiratory insufficiency requiring O2 therapy in 14.3% of cases. Two patients died. Predictive parameters of ILD deterioration were: DLCO<45% at ILD diagnosis and HRCT-scan pattern of usual interstitial pneumonia (UIP). CONCLUSION: Our series mainly underscores that ILD is frequent in anti-PL7 patients, leading to high morbidity. Our study further suggests that patients with predictive factors of ILD deterioration may require more aggressive therapy, especially the group of patients with DLCO<45% at ILD diagnosis and UIP pattern on HRCT-scan.

RESUMO

OBJECTIVES: To describe the safety and efficacy of single-port access for laparoscopic surgery in gynecology with conventional laparoscopic instruments. PATIENTS AND METHODS: In this prospective study, we report our experience with 90 patients who underwent Single Port Access (SPA) laparoscopic surgery for gynecologic pathology with the use of the SILS(®) Port Multiple Instrument Access Port (Covidien(®), Mansfield, MA). RESULTS: We realised 15 ovarian cystectomies, 30 salpingo-oophrectomies with 14 one side, 9 lysis of adhesions, 7 distal tubal repairs, 6 salpingectomy, 8 other procedures. The mean surgical time is 47 min (25-120). One conversion to conventional laparoscopy and one in laparotomy were performed. The mean duration stay is 2 days [1-3]. DISCUSSION AND CONCLUSION: SPA in gynecology is feasible with conventional laparoscopic instruments. SPA surgery represents the newest frontier in minimally invasive surgery.

RESUMO

OBJECTIVES: Pulmonary contusion (PC) is common in cases of polytrauma. The aim of this study was to perform a multivariate analysis of risk factors associated with the occurrence of infection in PC and analyze the microbiological epidemiology. PATIENTS AND METHODS: All patients with PC admitted to the intensive care unit (ICU) between January 2002 and December 2006 were included in this retrospective observational study. Patients with penetrating thoracic trauma or those who died in the 48hours following admission to hospital were excluded. Diagnosis of bacterial infection in PC was performed if hyperthermia was associated with a positive quantitative culture (103 colony forming units/mL) on the bronchial sample. Univariate analysis provided statistical difference between variables that were integrated in the multivariate analysis model. Multivariate analysis was then performed to determine the risk factors of bacterial infection in PC. RESULTS: One hundred and seventeen patients were included. The incidence of bacterial infection in PC was 33.3% (39 patients). The most frequently encountered bacteria were Haemophilus sp., Staphylococcus aureus, Enterobacteriaceae, Pseudomonas sp. and Streptococcus sp. According to multivariate analysis, the existence of hypothermia at hospital admission increased the risk of PC infection (OR=2.61; IC 95% [4.2-13.3]). CONCLUSION: In conclusion, PC was infected in 33.3% of cases. The existence of hypothermia was identified as a risk factor. A prospective study is warranted to confirm these results.

RESUMO

The aims of the present study were to: compare the characteristics between antisynthetase syndrome (ASS) patients with anti-Jo1 antibody and those with anti-PL7/PL12 antibody. The medical records of 95 consecutive patients with ASS were reviewed. Seventy-five of these patients had anti-Jo1 antibody; the other patients had anti-PL7 (n=15) or anti-PL12 (n=5) antibody. At ASS diagnosis, the prevalence of myalgia (p=0.007) and muscle weakness (p=0.02) was significantly lower in the group of anti-PL7/PL12-positive patients than in those with anti-Jo1 antibody; median value of CK (p=0.00003) was also lower in anti-PL7/PL12 patients. Anti-Jo1 positive patients developed more rarely myositis resolution (21.3% vs. 46.2%); in addition, the overall recurrence rate of myositis was higher in anti-Jo1 positive patients than in patients with anti-PL7/PL12 antibody (65.9% vs. 19.4%). Anti-Jo1-positive patients, compared with those with anti-PL7/PL12 antibody, more often experienced: joint involvement (63.3%vs. 40%) and cancer (13.3% vs. 5%). By contrast, anti-PL7/PL12 positive patients, compared with those with anti-Jo1 antibody, more commonly exhibited: ILD (90% vs. 68%); in anti-PL7/PL12 positive patients, ILD was more often symptomatic at diagnosis, and led more rarely to resolution of lung manifestations (5.6% vs. 29.4%). Finally, the group of anti-PL7/PL12 positive patients more commonly experienced gastrointestinal manifestations related to ASS (p=0.02). Taken together, although anti-Jo1 positive patients with ASS share some features with those with anti-PL7/PL12 antibody, they exhibit many differences regarding clinical phenotype and long-term outcome. Our study underscores that the presence of anti-Jo1 antibody results in more severe myositis, joint impairment and increased risk of cancer. On the other hand, the presence of anti-PL7/PL12 antibody is markedly associated with: early and severe ILD, and gastrointestinal complications. Thus, our study interestingly indicates that the finding for anti-Jo1 and anti-PL7/PL12 antibodies impacts both the long-term outcome and prognosis of patients with ASS.

RESUMO

OBJECTIVE: To report our experience using rituximab as therapy for refractory antisynthetase syndrome (ASS)-associated interstitial lung disease. METHODS: We retrospectively evaluated the medical records of 7 ASS patients with refractory interstitial lung disease, which had previously failed to respond to prednisone and/or other cytotoxic drugs. All 7 patients received rituximab therapy, i.e.: 1 g at days 0 and 14 and at 6-month follow-up. Data on pulmonary symptoms, pulmonary function tests and high resolution computed tomography (HRCT) scan of the lungs were collected: (1) before rituximab initiation; and (2) at 6-month and one-year follow-up after the first infusion of rituximab. RESULTS: At one-year follow-up, ASS patients had resolution (n = 2) or improvement of pulmonary clinical manifestations. Patients also exhibited significant improvement of interstitial lung disease parameters: 1) on pulmonary function tests: FVC (p = 0.03) and DLCO (p = 2 × 10(-5)); 2) and HRCT-scan of the lungs. Due to clinical resolution/improvement of interstitial lung disease, the median daily dose of oral prednisone could be reduced in these 7 ASS patients at one-year follow-up, compared with baseline (20 mg/day vs. 9 mg/day; p = 0.015). CONCLUSION: Our findings suggest that rituximab may be a helpful therapy for refractory interstitial lung disease in patients with ASS.

RESUMO

INTRODUCTION: Pathological endothelin axis is known to be involved in prostate cancer progression. Our study evaluates immunohistochemical expression of ET-1 and ET-AR on prostate biopsy specimen and the predictive value for biochemical relapse on patients with advanced and metastatic cancer. We also evaluated the impact of ET-1 and ET-AR expression on local progression and metastatic bone progression for these patients. PATIENTS AND METHOD: From 1992 to June 2009, 44 patients with clinical T3 stage and metastatic lymph nodes were included. PSA levels, Gleason score in biopsy cores, number of invaded lymph nodes, the existence of nodular capsule transgression and hormonal treatment given to the patient, were analyzed. Biopsy cores were submitted to immunohistochemical study of the expression of ET-1 and ET-AR. Semi-quantitative ET-1 and ET-AR staining assessment was always realised by the same pathologist. RESULTS: The average age of the cohort was 65.6 (standard deviation 6.3), median PSA level was 52.8 ng /ml (3-227), median time of follow-up was 70 months (6-144). Biochemical relapse was observed in 62.8%. Statistically significant stronger ET-1 expression was observed in biopsies of patients with a biochemical relapse (p=0.014). Eighty percent of patients with a biochemical relapse had a high level of ET-AR expression, but no statistical significance has been shown (p=0.109). The relative risk for progression under hormonal therapy was 1.9 in case of high level of ET-1 expression and biochemical relapse was confirmed 8 months earlier in average. High level of ET-AR expression on biopsy cores may indicate earlier local progression and metastatic bone progression but there were no statistical proof. CONCLUSION: In our study, the strength of ET-1 expression in prostate cancer biopsy cores is a prognostic factor of biochemical relapse for cT3 stage patients with metastatic lymph nodes. We have not been able to prove that ET-1 is an independent prognostic factor. A high level of ET-AR expression on prostate biopsy cores is not, in our study, a prognosis factor for predicting the biochemical relapse.

RESUMO

The aims of this present study were to: 1) assess the characteristics of hematological malignancies in polymyositis/polymyositis (PM/DM) patients; and 2) determine predictive variables of hematological malignancies in PM/DM patients. We retrospectively reviewed the medical records of 32 patients (14 PM, 18 DM) associated with hematological malignancies. In our 32 PM/DM patients, hematological malignancy was concurrently identified (18.8%) or occurred during the course of PM/DM (31.2%); although, PM/DM more often preceded hematological malignancy onset (50%). We observed that the types of hematological malignancies varied, consisting of: B-cell lymphoma (n=20), T-cell lymphoma (n=4), Hodgkin's disease (n=2), multiple myeloma (n=1), myelodysplastic syndrome without excess of blasts (n=3), hairy cell (n=1) and acute lymphocytic leukemia (n=1). In 21 patients of our 32 patients with PM/DM-associated hematological malignancy (65.6% of cases), PM/DM paralleled the course of hematological malignancy. Finally, we observed that patients with PM/DM-associated hematological malignancies had a poor prognosis, the survival status ranging from 96.9%, 78.1% and 51.4% at 1, 3 and 5years, respectively. Interestingly, we found that patients with hematological malignancies, compared with those without were older and more frequently had DM; on the other hand, these patients less commonly exhibited: joint involvement (p=0.017), interstitial lung disease (p=0.06) and anti-Jo1 antibody (p=0.001). Taken together, our study underscores that the association between PM/DM and hematological malignancy, especially lymphoma, should not be ignored. Our findings also suggest that antisynthetase syndrome may be a protective factor of hematological malignancy in PM/DM patients.

RESUMO

OBJECTIVE: This study was undertaken to assess the characteristics and outcome of interstitial lung disease (ILD) in polymyositis/dermatomyositis (PM/DM) and to determine variables predictive of ILD deterioration in PM/DM. METHODS: Among 348 consecutive patients with PM/DM, 107 patients with ILD were identified by medical records search in 4 medical centers. All patients underwent pulmonary function tests (PFTs) and pulmonary high-resolution computed tomography (HRCT) scan. RESULTS: ILD onset preceded PM/DM clinical manifestations in 20 patients, was identified concurrently with PM/DM in 69 patients, and occurred after PM/DM onset in 18 patients. Patients with ILD could be divided into 3 groups according to their presenting lung manifestations: patients with acute lung disease (n = 20), patients with progressive-course lung signs (n = 55), and asymptomatic patients with abnormalities consistent with ILD evident on PFTs and HRCT scan (n = 32). We observed that 32.7% of the patients had resolution of pulmonary disorders, whereas 15.9% experienced ILD deterioration. Factors that predicted a poor ILD prognosis were older age, symptomatic ILD, lower values of vital capacity and diffusing capacity for carbon monoxide, a pattern of usual interstitial pneumonia on HRCT scan and lung biopsy, and steroid-refractory ILD. The mortality rate was higher in patients with ILD deterioration than in those without ILD deterioration (47.1% versus 3.3%). CONCLUSION: Our findings indicate that ILD results in high morbidity in PM/DM. Our findings also suggest that more aggressive therapy may be required in PM/DM patients presenting with factors predictive of poor ILD outcome.

RESUMO

AIM: We assessed in this study the influence of contrast-enhanced CT (ceCT) on PET/CT interpretation and PET/CT on ceCT interpretation in patients with lymphoma, before and after chemotherapy. METHODS: Fifty patients with Hodgkin disease (N.=17) or non-Hodgkin lymphomas (N.=33) were assessed before and after chemotherapy. PET/CT were performed 60 minutes after injection of FDG. Iopamidol was then injected and followed, 50 seconds later, by another CT. PET images were successively reconstructed using non-enhanced CT (PET-) and ceCT (PET+). Four nuclear physicians rated PET- and PET+ in random order. Three radiologists initially rated ceCT alone and then ceCT along with PET+. RESULTS: Before chemotherapy, global agreement (GA) was 99% (k=0.96) when PET- was compared to PET+. Nine (5%) lesions were discordant, 5 according to PET- and 4 to PET+. After chemotherapy, GA was 99% (k=0.91). Eight (15%) lesions were discordant, 3 according to PET- and 5 to PET+. Before chemotherapy, GA was 97% (k=0.91) when ceCT was compared to ceCT with PET+. Twenty-one (12%) lesions were discordant, 16 when ceCT were analyzed alone and 5 when ceCT was analyzed with PET+. After chemotherapy, GA was 95% (k=0.76). All 30 (35%) discordant lesions were positive according to ceCT alone. A significant difference between the 2 procedures was found in the pelvis and in the groin (P<0.05). CONCLUSION: PET+ did not differ from PET-, before and after chemotherapy. Fewer abnormalities were observed, when ceCT was analyzed with PET+, particularly after chemotherapy, due to residual masses that are better analyzed with functional imaging.

RESUMO

The life expectancy of patients with localized prostate cancer at treatment initiation has increased, and post-treatment quality of life has become a key issue. The aim of this study is to assess the impact of Radical prostatectomy (RP) on patients' sexual health and satisfaction according to sexual motivation using a self-administered questionnaire completed by two groups of RP patients, with high or lower levels of sexual motivation. A total of 63 consecutive patients were included (mean age, 63.9 years), of whom 74.6% were being treated for erectile dysfunction (ED). After RP, patients reported lower sexual desire (52.4%), reduced intercourse frequency (79.4%), anorgasmia (39.7%), less satisfying orgasm (38.1%), climacturia (25.4%), greater distress (68.3%) and/or lower partner satisfaction (56.5%). Among the most sexually motivated patients, 76.0% reported loss of masculine identity, 52% loss of self-esteem and 36.0% anxiety about performance. These rates were lower among less motivated patients (52.6, 28.9, and 18.4%, respectively). Mean overall satisfaction score was 4.8 ± 2.9. The score was significantly lowered in motivated than less motivated patients (3.4 vs 5.8) (P = 0.001). In conclusion, RP adversely affected erectile and orgasmic functions but also sexual desire, self-esteem and masculinity. The more motivated patients experienced greater distress and were less satisfied.

RESUMO

PURPOSE: Patients with permanent cardiac pacemakers occasionally require radiotherapy. Therapeutic irradiation may cause pacemakers to malfunction due to the effects of ionizing radiation or electromagnetic interference. We studied the breast cancer patients who needed breast and/or chest wall and lymph node irradiation to assess the feasibility and tolerance in this population of patients. PATIENTS AND METHODS: From November 2008 to December 2009, more than 900 patients received radiotherapy for their breast cancer in our department using megavoltage linear accelerator (X 4-6 MV and electrons). Among them, seven patients were with permanent pacemaker. All patients have been treated to the breast and chest wall and/or lymph nodes. Total dose to breast and/or chest wall was 50 Gy/25 fractions and 46 Gy/23 fractions to lymph nodes. Patients who underwent conserving surgery followed by breast irradiation were boosted when indicated to tumour bed with 16 Gy/8 fractions. All patients were monitored everyday in presence of radiation oncologist to follow the function of their pacemaker. All pacemakers were controlled before and after radiotherapy by the patients' cardiologist. RESULTS: Seven patients were referred in our department for postoperative breast cancer radiotherapy. Among them, only one patient was declined for radiotherapy and underwent mastectomy without radiotherapy. In four cases the pacemaker was repositioned before the beginning of radiotherapy. Six patients, aged between 48 and 84 years underwent irradiation for their breast cancer. Four patients were treated with conserving surgery followed by breast radiotherapy and two with mastectomy followed by chest wall and internal mammary chain, supra- and infra-clavicular lymph node irradiation. The dose to the pacemaker generator was kept below 2 Gy. There was no pacemaker dysfunction observed during the radiotherapy. CONCLUSION: The multidisciplinary work with position change of the pacemaker before radiotherapy and everyday monitoring permitted the safe treatment of our patients. Updated guidelines are definitely needed with more details about acceptable doses at the different parts of the pacemaker.
