RESUMEN

BACKGROUND & AIMS: Beyond cardiovascular disease protection, the health consequences of very low concentrations of low-density lipoprotein-cholesterol (LDL-C) remain a matter of debate. In primary hypobetalipoproteinemia (HBL), liver steatosis and cirrhosis have occasionally been reported. Here, we aimed to investigate the association between HBL and the risk of hepatic complications (cirrhosis complications and/or primary liver cancer) in the general population. METHODS: A cohort study was conducted in the French population-based cohort CONSTANCES. Participants with primary HBL (LDL-C <5th percentile for age and sex, [HBL]) were compared with those with normal LDL-C concentrations (40th-60th percentile, [Control]). Participants on lipid-lowering therapies were excluded. For hepatic complications, follow-up events were compared by calculating the incidence density ratio (IDR). The same analyses were replicated in the UK Biobank (UKBB) cohort. RESULTS: In the CONSTANCES and UKBB cohorts, 34,653 and 94,666 patients were analyzed, with median ages of 45 and 56 years, mean LDL-C concentrations (HBL vs. control) of 71 vs. 128 mg/dl and 86 vs. 142 mg/dl, and mean follow-up durations of 5.0 and 11.5 years, respectively. The HBL group presented a higher incidence of hepatic complications than the control group: 0.32/ vs. 0.07/1,000 person-years (IDR = 4.50, 95% CI 1.91-10.6) in CONSTANCES, and 0.69/ vs. 0.21/1,000 person-years (IDR = 3.27, 95% CI 2.63-4.06) in the UKBB. This risk proved to be independent of classic risk factors for liver disease (obesity, alcohol consumption, diabetes, viral hepatitis), including in a 5-year landmark analysis excluding early events. Sensitivity analyses based on apoliprotein-B levels (instead of LDL-C levels) or genetically defined HBL showed similar results. CONCLUSIONS: HBL is associated with a markedly increased risk of hepatic complications. HBL must be considered as a substantial independent risk factor for liver diseases which justifies specific prevention and screening. IMPACT AND IMPLICATIONS: Hypobetalipoproteinemia (HBL) is a lipid disorder characterized by permanent, inherited low levels (below the 5th percentile) of low-density lipoprotein-cholesterol. While HBL is associated with a lower risk of cardiovascular events, some studies suggest that it may be associated with a potential risk of hepatic steatosis and hepatic complications. Here, we studied the association between HBL and hepatic complications (defined as cirrhosis complications and/or primary liver cancer) in two populations of several hundred thousand people, both in France (CONSTANCES cohort) and the United Kingdom (UKBB). The results show that HBL is associated with a significant and independent excess risk of hepatic complications, including primary liver cancer. Thus, in people with HBL, the value of regular liver monitoring must be studied.

RESUMEN

Follicular lymphoma (FL) is an indolent non-Hodgkin's lymphoma with heterogeneous outcomes. Progression or relapse of FL within 2 years (so-called POD24) after diagnosis is associated with a poor outcome for patients treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, prednisone) in clinical trials. POD24 needs further validation before it can be used as a relevant endpoint to assess treatment efficacy. In the present retrospective monocentric study, we investigated the predictive value of POD24 in a cohort of grade 1, 2, or 3a FL patients treated in our institution (Nantes Medical University, France) and registered in our local database. We investigated the nature of treatment lines, patients' outcomes, and the prognostic value of POD24. Between 2007 and 2016, 317 patients were included. After first-line therapy, 60 patients relapsed within 2 years (POD24-pos cohort), and 254 patients did not relapse within 2 years (PO24-neg cohort). Thirty-three patients died, and 34 patients had an aggressive transformation. The median follow-up is 59.9 months (1.6-395.5). The median PFS is 59.9 months. Overall survival (OS) at 1 year, 3 years, and 5 years is 98.4% [97.0-99.8], 95.1% [92.6-97.6], and 92.5% [89.3-95.9], respectively. The 5-year OS was statistically lower for POD24-pos patients (82% [71.9-93.5]) than for POD24-neg patients (93.3% [88.98-97.8]) (p = 10-5). In multivariate analyses, transformation was predictive of OS, and PS (≥ 1) was predictive of POD24. POD24 is predictive of a worse OS and may be recommended as a relevant endpoint in clinical trials and in real life in particular for patients with advanced disease.

RESUMEN

BACKGROUND: Mild primary hyperparathyroidism (serum calcium ≤ 2.85 mmol/L) is the most representative form of pHPT nowadays. The aim of this study was to evaluate its subtypes and the multiglandular disease (MGD) rate as it may lower the sensitivity of preoperative parathyroid scintigraphy and the surgical cure rate. METHODS: We retrospectively included patients with mild pHPT who underwent parathyroid dual-tracer scintigraphy with 99mTc-MIBI SPECT/CT and surgery between January 2013 and December 2015. Cure was defined as normalization of serum calcium (or PTH in the normocalcemic form) at 6 months. MGD was defined by either two abnormal resected glands or persistent disease after resection of at least one abnormal gland. RESULTS: We included 121 patients. Median preoperative serum calcium was 2.68 mmol/L and median PTH was 83.4 pg/mL. A total of 141 glands were resected (95 adenomas, 33 hyperplasias). The subtypes were 57% classic, 32.2% normohormonal, and 10.7% normocalcemic. MGD occurred in 23.5% of patients divided as 13%, 30%, and 64% respectively (p = 0.0011). The surgical cure rate was 85.2%. The normocalcemic form had lower cure rate than the normohormonal (45% vs 84%, p = 0.018) and classic forms (45% vs 93%, p = 0.0006). MIBI scintigraphy identified at least one abnormal lesion, later confirmed by the pathologist in 90/98 patients, making the sensitivity per patient 91.8% (95% CI 84.1-96.2%). CONCLUSIONS: MGD is strongly associated with mild pHPT, especially the normocalcemic form where it accounts for 64% of cases. Bilateral neck exploration should be performed in this population to improve the cure rate, even if the scintigraphy shows a single focus.

RESUMEN

BACKGROUND: Hypobetalipoproteinemia (HBL) is defined by plasma concentrations of LDL-cholesterol (LDL-C) lower than the fifth percentile for age and sex. Several psychiatric symptoms have been reported in association with HBL. The objective was to assess the prevalence of primary HBL in patients hospitalized in a psychiatric population and to better characterize the related psychiatric disorders. METHODS: HYPOPSY is a retrospective study including 839 adults hospitalized in the Psychiatry department of Nantes University Hospital during the year 2014, except patients with eating disorders. The prevalence of primary HBL was defined by a plasma LDL-C concentration ≤ 50 mg/dL. Secondary causes of HBL were excluded after a review of medical records (n=2). Related-psychiatric disorders in patients with and without HBL were recorded using the ICD-10 classification. RESULTS: Twenty cases of primary HBL (mean [SD] LDL-C: 42 [7] mg/dL) were diagnosed, leading to a prevalence of 2.39%. In comparison, the prevalence of HBL in a healthy control population was 0.57%. Psychiatric patients with HBL were characterized by a higher frequency of schizophrenia (p=0.044), hetero-aggression (p=0.015) and pervasive and specific developmental disorders (including autism) (p=0.011). CONCLUSIONS: The prevalence of HBL is 4-fold higher in psychiatric than in general population. More specifically, some statistically significant associations were found between low LDL-C concentrations and schizophrenia, autism and hetero-aggression. These data reinforce the hypothesis for a link between genetically low LDL-C levels and psychiatric disorders.

RESUMEN

The increasing number of breast cancer cases may induce longer waiting times (WT), which can be a source of anxiety for patients and may play a role in survival. The aim of this study was to examine the factors, in particular socio-economic factors, related to treatment delays. Using French Cancer Registry databases and self-administered questionnaires, we included 1,152 women with invasive non-metastatic breast cancer diagnosed in 2007. Poisson regression analysis was used to identify WTs' influencing factors. For 973 women who had a malignant tissue sampling, the median of overall WT between the first imaging procedure and the first treatment was 44 days (9 days for pathological diagnostic WT and 31 days for treatment WT). The medical factors mostly explained inequalities in WTs. Socio-economic and behavioral factors had a limited impact on WTs except for social support which appeared to be a key point. Better identifying the factors associated with increase in WTs will make it possible to develop further interventional or prospective studies to confirm their causal role in delay and at last reduce disparities in breast cancer management.

RESUMEN

Only limited population-based data are available on mantle cell lymphoma (MCL), a relatively rare and aggressive mature B cell non-Hodgkin lymphoma (NHL) entity. We conducted an epidemiological study based on the three French registries devoted to haematological malignancies over the period 2002-2006. Main clinical features and management characteristics were collected. Incidence and survival rates were estimated, and independent prognostic factors were analysed. MCL was diagnosed in 135 patients between 2002 and 2006. Seventy-four percent of patients were men. Age-standardised incidence rate of MCL (per 100,000) was 1.1 in men and 0.26 in women. Median age at diagnosis was 72 years (range 30-92). Advanced-stage (III or IV) disease was diagnosed in 81.5 % of patients, and 55 % of them were identified as high risk according to MCL International Prognostic Index (MIPI). Median net survival time was 41 months (95 % confidence interval (CI), 38-62). Main independent prognostic factors were age at diagnosis, performance status and use of rituximab in first-line treatment. Median overall survival was 36 months (95 % CI, 27-40) for high MIPI and 60 months (95 % CI, 35-74) for low/intermediate MIPI patients (p = 0.02). This study confirms that MCL remains an aggressive NHL with a median overall survival less than 4 years and demonstrates that the use of rituximab has modified overall survival duration.

RESUMEN

Autologous stem cell transplantation (ASCT) is considered as an attractive treatment option for young mantle cell lymphoma (MCL) patients. This retrospective SFGM-TC study analyzed the outcome of 500 MCL patients treated with ASCT and investigated parameters that may modify the outcome of patients who proceeded to ASCT upfront (n=396). For all patients, median age at ASCT was 56 years (range, 26-71). Median follow-up was 34 months. Three-year progression free survival (PFS) and overall survival (OS)were 63.5% [95 % CI, 58.7­68.6 %] and 79.5 % [95 % CI, 75.3­83.4 %], respectively. Median time from ASCT to relapse was 22 months (range, 0­136 m). For patients transplanted upfront and in multivariate analysis, age (HR=2 [1.2­3.4], p=.01, and HR=2.3 [1.2­4.5], p=.01), disease status at time of ASCT (HR=1.7 [1.1­2.6], p=.01 and HR=1.8 [1.1­3.1], p=.03), and use of rituximab (HR=0.5 [0.3­0.8], p=.002 and HR=0.5 [0.3­0.9], p=.01) were statistically predictive for both PFS and OS. Also, first line treatment including anthracycline and high-dose cytarabine followed by ASCT conditioned with TAM improved PFS. To conclude, this study suggests that ASCT in MCL can provide a high response rate but may not be sufficient to cure MCL even when ASCT is performed upfront, highlighting the need for innovative approaches before ASCT, aiming to increase complete response rate, and after ASCT, to maintain response.

RESUMEN

Autologous stem cell transplantation (ASCT) is considered as an attractive treatment option for young mantle cell lymphoma (MCL) patients. This retrospective SFGM-TC study analyzed the outcome of 500 MCL patients treated with ASCT and investigated parameters that may modify the outcome of patients who proceeded to ASCT upfront (n = 396). For all patients, median age at ASCT was 56 years (range, 26-71). Median follow-up was 34 months. Three-year progression free survival (PFS) and overall survival (OS) were 63.5 % [95 % CI, 58.7-68.6 %] and 79.5 % [95 % CI, 75.3-83.4 %], respectively. Median time from ASCT to relapse was 22 months (range, 0-136 m). For patients transplanted upfront and in multivariate analysis, age (HR = 2 [1.2-3.4], p = .01, and HR = 2.3 [1.2-4.5], p = .01), disease status at time of ASCT (HR = 1.7 [1.1-2.6], p = .01 and HR = 1.8 [1.1-3.1], p = .03), and use of rituximab (HR = 0.5 [0.3-0.8], p = .002 and HR = 0.5 [0.3-0.9], p = .01) were statistically predictive for both PFS and OS. Also, first line treatment including anthracycline and high-dose cytarabine followed by ASCT conditioned with TAM improved PFS. To conclude, this study suggests that ASCT in MCL can provide a high response rate but may not be sufficient to cure MCL even when ASCT is performed upfront, highlighting the need for innovative approaches before ASCT, aiming to increase complete response rate, and after ASCT, to maintain response.

RESUMEN

BACKGROUND: Intradermal injections of botulinum toxin are effective but transitory in primary palmar hyperhidrosis. These injections are repeated when the symptoms recur. We do not know how the duration of efficacy changes when injections are repeated. OBJECTIVE: In this retrospective study, we aimed to investigate the change in the duration of efficacy of botulinum toxin A (Dysport, Ipsen, Boulogne-Billancourt, France) with the repetition of injections in patients with primary palmar hyperhidrosis. METHODS: From May 2001 to April 2012, 28 patients were treated with a dose of 250 U of botulinum toxin A per palm. We compared the duration of efficacy of the first and last toxin injections. RESULTS: The median duration of efficacy was 7 months for the first injection and 9.5 months for the last, the difference being statistically significant (P = .0002). LIMITATIONS: Study limitations include a relatively small number of patients treated at a single center and evaluated retrospectively. CONCLUSION: To our knowledge, this study is the first to report a significant increase in the duration of efficacy of botulinum toxin A injections with the repetition of injections in patients with primary palmar hyperhidrosis. The reasons for this effect may be linked to the mechanism of action of botulinum toxin, and may improve our understanding of its pharmacologic effects.

RESUMEN

OBJECTIVE: Identifying the principal difficulties to general physicians in the administrative region of Loire-Atlantique to determining the medical time of personal incapacity in daily life named ITT in French legislation linked to wounds. METHODS: A study was performed by an anonym self-assessment questionnaire including 200 GPs. The study was divided in five sections (doctor's profile, self evaluation of establishing medical description of violence and evaluating ITT, questions about theoretical knowledge of ITT, medical difficulties during the assessment of wounds, and free medical comments). RESULTS: The answer rate was 50,5% of included GPs. 90,4% of medical doctor drafted medical certificate for assault victims. Only 55% of GPs fixed ITT systematically. They were influenced by the importance of assault. They express difficulties about the psychological troubles following assault. These two results were the most medical difficulties during their evaluation. DISCUSSION: The legal consequences of while incapacity is not sufficiency mastered. The psychological troubles resulting of assault is difficult to estimating for a lot of GPs. The medical doctors collect the patient pressure to increase time of personal incapacity in daily life. Lack of academic training and absence of legal ITT references are reproached by GPs. CONCLUSION: Medical certificate of stoppage work is now known as different as the time of personal incapacity for GPs. This way, we think that the evaluation of the ITT has to remain an act of GPs. if difficulties are reported by GPs, the medical testifying will be improved by references and tables which do not exist this day on the subject.

RESUMEN

BACKGROUND: According to a meta-analysis of randomized clinical trials, paclitaxel-coated devices (PCDs) for lower limb endovascular revascularization may be associated with increased risk of late mortality. OBJECTIVES: The purpose of this study was to determine whether PCDs are associated with all-cause mortality in a real-world setting. METHODS: DETECT is a nationwide, exhaustive retrospective cohort study using medico-administrative data from the French National Healthcare System representing >99% of the population. The main selection criterion was the first procedure of interest: endovascular revascularization for lower limb peripheral artery disease involving ≥1 balloon and/or stent performed between October 1, 2011, and December 31, 2019. Patients with or without PCDs were compared for all-cause mortality until December 31, 2021. RESULTS: A total of 259,137 patients were analyzed, with 20,083 (7.7%) treated with ≥1 PCD. After a median follow-up of 4.1 years (Q1-Q3: 2.3-6.4 years), a total of 5,385 deaths/73,923 person-years (PY) (7.3/100 PY) and 109,844 deaths/1,060,513 PY (10.4/100 PY) were observed in the PCD and control groups, respectively. After adjustment for confounding factors, PCD treatment was associated with a lower risk of mortality in multivariable Cox analyses (HR: 0.86; 95% CI: 0.84-0.89; P < 0.001). Similar results were observed using propensity score matching approaches based on either nearest-neighbor or exact matching. CONCLUSIONS: In a nationwide analysis based on large-scale real-world data, exposure to PCDs was not associated with a higher risk of mortality in patients undergoing endovascular revascularization for lower limb peripheral artery disease.

RESUMEN

Background: Biomedical data warehouses (BDWs) have become an essential tool to facilitate the reuse of health data for both research and decisional applications. Beyond technical issues, the implementation of BDWs requires strong institutional data governance and operational knowledge of the European and national legal framework for the management of research data access and use. Objective: In this paper, we describe the compound process of implementation and the contents of a regional university hospital BDW. Methods: We present the actions and challenges regarding organizational changes, technical architecture, and shared governance that took place to develop the Nantes BDW. We describe the process to access clinical contents, give details about patient data protection, and use examples to illustrate merging clinical insights. Unlabelled: More than 68 million textual documents and 543 million pieces of coded information concerning approximately 1.5 million patients admitted to CHUN between 2002 and 2022 can be queried and transformed to be made available to investigators. Since its creation in 2018, 269 projects have benefited from the Nantes BDW. Access to data is organized according to data use and regulatory requirements. Conclusions: Data use is entirely determined by the scientific question posed. It is the vector of legitimacy of data access for secondary use. Enabling access to a BDW is a game changer for research and all operational situations in need of data. Finally, data governance must prevail over technical issues in institution data strategy vis-à-vis care professionals and patients alike.

RESUMEN

BACKGROUND: Intradermal injections of botulinum toxin are effective but transitory in primary axillary hyperhidrosis. These injections are repeated when the symptoms recur. The reported duration of efficacy is variable, from 2 to 24 months, but it is unknown how the duration of efficacy changes when injections are repeated. OBJECTIVE: In this retrospective study, we aimed to evaluate changes in the duration of efficacy of botulinum toxin injections (Dysport, Ipsen, Boulogne-Billancourt, France) with the repetition of injections in patients with axillary hyperhidrosis. METHODS: From May 2001 to April 2012 inclusive, 83 patients were treated with a dose of 125 U per underarm. We compared the duration of effect of the first and last toxin injections. RESULTS: The median duration of efficacy for the first injection was 5.5 months, whereas that for the last injection was 8.5 months. The difference between these 2 durations is statistically significant (P = .0002). LIMITATIONS: Although retrospective and based on the declarative, this work is the first to our knowledge to highlight this benefit of treatment and to evaluate botulinum toxin over such a long period (11 years). CONCLUSION: There appears to be an increase in the duration of efficacy of botulinum toxin A injections with the repetition of injections in patients with primary axillary hyperhidrosis. The reasons for this effect may be linked to the mechanism of action of botulinum toxin, and may improve our understanding of its pharmacologic effects.

RESUMEN

Gene prognostic meta-analyses should benefit from breast tumour genomic data obtained during the last decade. The aim was to develop a user-friendly, web-based application, based on DNA microarrays results, called "breast cancer Gene-Expression Miner" (bc-GenExMiner) to improve gene prognostic analysis performance by using the same bioinformatics process. bc-GenExMiner was developed as a web-based tool including a MySQL relational database. Survival analyses are performed with R statistical software and packages. Molecular subtyping was performed by means of three single sample predictors (SSPs) and three subtype clustering models (SCMs). Twenty-one public data sets have been included. Among the 3,414 recovered breast cancer patients, 1,209 experienced a pejorative event. Molecular subtyping by means of three SSPs and three SCMs was performed for 3,063 patients. Furthermore, three robust lists of stable subtyped patients were built to maximize reliability of molecular assignment. Gene prognostic analyses are done by means of univariate Cox proportional hazards model and may be conducted on cohorts split by nodal (N), oestrogen receptor (ER), or molecular subtype status. To evaluate independent prognostic impact of genes relative to Nottingham Prognostic Index and Adjuvant! Online, adjusted Cox proportional hazards models are performed. bc-GenExMiner allows researchers without specific computation skills to easily and quickly evaluate the in vivo prognostic role of genes in breast cancer by means of Cox proportional hazards model on large pooled cohorts, which may be split according to different prognostic parameters: N, ER, and molecular subtype. Prognostic analyses by molecular subtype may also be performed in three robust molecular subtype classifications.

RESUMEN

PURPOSE: Exceptionally high incidence rates of thyroid cancer have been observed in New Caledonia, particularly in Melanesian women, but familial aggregation of thyroid diseases in this population is unknown. We study the association between family history of malignant or benign thyroid diseases and non-medullary thyroid cancer in this country. METHODS: We conducted a population-based case-control study including 332 cases with papillary or follicular carcinoma diagnosed in 1993-1999 and 412 controls, matched by sex and 5-year age-group. RESULTS: Thyroid cancer was associated with a history of thyroid cancer in first-degree relatives (odds ratio (OR), 3.2; 95 % CI, 1.6-6.2) and with a family history of multinodular goiter (OR, 3.6; 95 % CI, 1.9-7.0). The ORs did not change by age at diagnosis and with the number of affected relatives. The study provides evidence that the familial component of thyroid cancer is particularly strong in men. Thyroid cancer was not associated with a family history of thyroid diseases in Melanesians from the Loyalty Islands, the area with the highest incidence rates for thyroid cancer, possibly indicating a high frequency of genetic susceptibility variants and lack of genetic variation in this population subgroup. CONCLUSION: Overall our findings confirm an elevated risk of thyroid cancer in individuals with a family history of malignant or benign thyroid diseases, particularly in Melanesians where familial aggregation of thyroid cancer had never been investigated before. The study of genetic variants in candidate susceptibility genes for thyroid cancer may help clarifying the absence of an association in the subgroup of Melanesians from the Loyalty Islands.

RESUMEN

OBJECTIVE: To develop and validate a list of criteria to assess the causes of inappropriate hospital days for patients admitted to rehabilitation centres and sub-acute care units. DESIGN: The tool was developed by a multidisciplinary panel of 33 experts, using a formalized consensus method. It collects both the needs of patients (distinguishing healthcare needs (9 criteria) and accommodation needs (9 criteria)) and the reasons for inappropriateness (19 criteria). Inappropriate days were identified using the tool to assess appropriateness of hospital days validated previously. Reliability was studied by measuring agreement between two independent simultaneous ratings. SETTING: The validation study was performed on a randomized sample of 576 hospital days from 22 wards in France. MAIN OUTCOME MEASURES: Inter-rater reliability was evaluated using the κ-statistic and prevalence-adjusted and bias-adjusted kappa (PABAK). RESULTS: For patient accommodation needs, the inter-rater reliability was estimated by a κ-value of 0.80 (95% confidence interval (95% CI) 0.66-0.92) and a PABAK of 0.80 (95% CI 0.63-0.91). There was good agreement on the reasons for inappropriateness, with κ-values from 0.30 to 0.60 and PABAK from 0.46 to 0.69. The κ-coefficient varied from 0.33 to 0.49 for the assessment of patient healthcare needs, with PABAK ranging from 0.49 to 0.72. CONCLUSIONS: The instrument is suitable and valid to assess the causes of inappropriate hospital days in rehabilitation centres and sub-acute care units. The study showed that the tool can be easily used by healthcare workers, which makes it useful for quality improvement.

RESUMEN

BACKGROUND: Intravascular large B-cell lymphoma (lVLBCL) is a very rare type of large B-cell lymphoma. METHODS: We conducted a retrospective study on IVLBCL patients treated from 2000 to 2016 in LYSA cooperative group centers. RESULTS: Sixty-five patients were identified in 23 centers. Median age at diagnosis was 69 years (range 23-92). Thirty-four patients (64%) had an IPI score >3 and 40 patients (67%) had a performance status ≥2. The most frequent extra-nodal locations were bone marrow (n = 34; 52%), central nervous system (n = 25; 39%), and skin (n = 21; 33%). Nodal involvement and endocrine system were observed in 34% (n = 22) and 18% (n = 12) of all cases, respectively. Twenty-six patients (41%) had macrophage activation syndrome. Tumor cells were frequently CD5 positive (52%) with a non-germinal center origin (86%). BCL2 was expressed in 87% of all samples analyzed (n = 20) and 43% of patients had a MYC/BCL2 double expression. Fifty-six patients were treated with a regimen of chemotherapy containing rituximab, among whom 73% reached complete remission. The median progression-free survival (PFS) and median overall survival (OS) were 29.4 months and 63.8 months, respectively. History of autoimmune disorder (Hazard ratio [HR] 3.3 [1.4-7.8]; p < 0.01), nodal involvement (HR 2.6 [1.4-5.1]; p < 0.01), lack of anthracycline (HR 0.1 [0-0.4] for use; p < 0.001), or no intensification at first-line regimen (p = 0.02) were associated with worse PFS. High-dose methotrexate use was not associated with better PFS or OS. CONCLUSIONS: Our study highlights the aggressive clinical picture of IVLBCL, in particular the frequency of macrophage activation syndrome, and the need for new therapies despite a response to R-CHOP-like regimen similar to non-intravascular diffuse large B-cell lymphomas.

RESUMEN

BACKGROUND: The feasibility and safety of oxaliplatin-based hyperthermic intraperitoneal chemotherapy (HIPEC) associated with cytoreductive surgery (CRS) was assessed in patients with peritoneal carcinomatosis resulting from primary advanced or relapsing epithelial ovarian cancer (EOC). METHODS: Thirty-one patients received neoadjuvant platin-based chemotherapy followed by oxaliplatin-based HIPEC associated with CRS as consolidation of primary therapy (n = 19) or for relapsing disease (n = 12). Grade 3/4 complications were recorded according to National Cancer Institute definitions. RESULTS: Median peritoneal carcinomatosis index (PCI) was 2.7 after neoadjuvant chemotherapy. Mean duration of surgery was 352 min (range 105-614) and median hospital stay was 11 days (range 6-87). Grade 3 toxicity was observed in nine patients: five required repeat surgery, two an invasive procedure, four rehospitalization, and three a return to the ICU. No grade 4 toxicity occurred, excepted one hypokalemia. Median progression-free survival (PFS) for primary advanced EOC was 13.2 months and 1-year PFS was 59.3%. Median PFS for relapsing patients was 14.3 months and 1-year PFS was 54.4%. CONCLUSION: CRS with oxaliplatin-based HIPEC is feasible and relatively safe in recurrent and primary EOC. HIPEC after neoadjuvant chemotherapy reduces the PCI and decreases the number of surgical procedures and morbidity. Further evaluations of this procedure are required to assess the survival benefits.

RESUMEN

PURPOSE: The aim of this study was to compare retrospectively 18F-DOPA PET/CT versus 68Ga-DOTANOC PET/CT in a group of patients affected by midgut NET. PATIENTS AND METHODS: Patients with histologically proven grade 1 or grade 2 midgut NET were explored after injection of 150 MBq of 68Ga-DOTANOC and 210 MBq of 18F-DOPA. The PET/CTs were analyzed visually and semiquantitatively at the patient level, regional level (7 defined regions), and lesion level (maximum of 5 lesions/organ). The criterion standard was determined on the basis of histology and imaging follow-up. RESULTS: Thirty patients (17 males and 13 females; median age, 63.5 years [37-82 years]) were included. Both PET/CTs were negative in 3 patients and positive in 25 patients. PET/CTs were discordant in 2 patients, with 18F-DOPA positive and 68Ga-DOTANOC negative. 18F-DOPA PET/CT detected more involved regions and more metastatic lesions than 68Ga-DOTANOC PET/CT in 6 (20%) and 10 (33.3%) patients, respectively. Of the 81 confirmed affected regions, 77 (95%) were detected by 18F-DOPA PET/CT and 71 (87.7%) by 68Ga-DOTANOC PET/CT (P < 0.0001). 18F-DOPA PET/CT detected significantly more lesions (211/221) than 68Ga-DOTANOC PET/CT (195/221), corresponding to a sensitivity of 95.5% and 88.2%, respectively (P < 0.0001). Tumor-to-background ratios were more favorable in liver for 18F-DOPA than for 68Ga-DOTANOC. Interestingly, a correlation was found between 18F-DOPA SUVmax and tumor burden and especially with the number of regions involved by the disease (P = 0.019). CONCLUSIONS: 18F-DOPA PET/CT is superior to 68Ga-DOTANOC PET/CT for the detection of lesions, and when available, this tracer may be recommended as the first-line examination for an accurate staging of midgut NET.
