RESUMEN
BACKGROUND: Prior studies showed that during the coronavirus disease 2019 (COVID-19) pandemic healthcare workers had a higher risk of developing post-traumatic stress disorder (PTSD) symptoms. However, studies conducted among doctors several years after the beginning of the COVID-19 pandemic are scarce. AIMS: To evaluate the prevalence of PTSD among hospital doctors and to describe potential explanatory factors. METHODS: The Protec-Cov study was an observational, cross-sectional, multicentre study, which used an anonymous online questionnaire to evaluate PTSD in doctors from six hospitals in France between December 2021 and March 2022. The presence of PTSD was assessed using the Post-traumatic Stress Disorder Checklist Scale (PCLS) questionnaire with a cut-off of 44. RESULTS: Among the 307 doctors included, 18% presented a PCLS ≥44. The multivariate analysis showed that factors associated with a PCLS ≥44 were having a higher workload than before the COVID-19 pandemic (odds ratio [OR]â =â 4.75; 95% confidence interval [CI] 1.68-13.38), not feeling recognized within the professional environment (ORâ =â 2.83; 95% CI 1.26-6.33), and feeling isolated because of the lockdown (ORâ =â 4.2; 95% CI 1.97-8.95). Approximately 30% of hospital doctors (nâ =â 91) felt a need for psychological support but only 31% of them (nâ =â 28) received support. CONCLUSIONS: Based on our findings, a high prevalence of PTSD was observed among hospital doctors 2 years after the beginning of the COVID-19 pandemic. This study supports an early diagnosis of PTSD in this category of healthcare workers and warrants further study.

BACKGROUND: European guidelines propose a 0·5 mg kg-1 per day dose of oral prednisone as initial treatment for bullous pemphigoid (BP). We assessed the safety and efficacy of this regimen depending on BP extent and general condition of the patients. METHODS: In a prospective international study, we consecutively included all patients diagnosed with BP. Patients received a 0·5 mg kg-1 per day dose of prednisone, which was then gradually tapered 15 days after disease control, with the aim of stopping prednisone or maintaining minimal treatment (0·1 mg kg-1 per day) within 6 months after the start of treatment. The two coprimary endpoints were control of disease activity at day 21 and 1-year overall survival. Disease severity was assessed according to the Bullous Pemphigoid Disease Area Index (BPDAI) score. RESULTS: In total, 198 patients were included between 2015 and 2017. The final analysis comprised 190 patients with a mean age of 80·9 (SD 9·1) years. Control of disease activity was achieved at day 21 in 119 patients [62·6%, 95% confidence interval (CI) 55·3-69.5]; 18 of 24 patients (75%, 95% CI 53·3-90·2), 75 of 110 patients (68·8%, 95% CI 59·2-77·3) and 26 of 56 patients (46.4%, 95% CI 33·0-60·3) had mild, moderate and severe BP, respectively (P = 0·0218). A total of 30 patients died during the study. The overall Kaplan-Meier 1-year survival was 82·6% (95% CI 76·3-87·4) corresponding to 90·9%, 83·0% and 80·0% rates in patients with mild, moderate and severe BP, respectively (P = 0·5). Thresholds of 49 points for BPDAI score and 70 points for Karnofsky score yielded maximal Youden index values with respect to disease control at day 21 and 1-year survival, respectively. CONCLUSIONS: A 0·5 mg kg-1 per day dose of prednisone is a valuable therapeutic option in patients with mild or moderate BP whose general condition allows them to be autonomous.

INTRODUCTION: The Confusion Assessment Method (CAM) is a validated key tool in clinical practice and research programs to diagnose delirium and assess its severity. There is no validated French version of the CAM training manual and coding guide (Inouye SK). The aim of this study was to establish a consensual French version of the CAM and its manual. METHODS: Cross-cultural adaptation to achieve equivalence between the original version and a French adapted version of the CAM manual. RESULTS: A rigorous process was conducted including control of cultural adequacy of the tool's components, double forward and back translations, reconciliation, expert committee review (including bilingual translators with different nationalities, a linguist, highly qualified clinicians, methodologists) and pretesting. A consensual French version of the CAM was achieved. CONCLUSION: Implementation of the CAM French version in daily clinical practice will enable optimal diagnosis of delirium diagnosis and enhance communication between health professionals in French speaking countries. Validity and psychometric properties are being tested in a French multicenter cohort, opening up new perspectives for improved quality of care and research programs in French speaking countries.

BACKGROUND: Rectal cancer in patients aged ≥ 80 years is increasingly more frequent. Little is known regarding their clinical history and outcome after treatment. This retrospective study was undertaken to provide data on this situation. MATERIAL AND METHOD: A questionnaire was sent to the medical doctors of 414 patients listed in the database of Régime Général of Sécurité Sociale, living in the Provence-Alpes-Côte d'Azur (PACA) region between 2002 and 2005, aged ≥ 80 years, and registered as having rectal cancer. Survival was analyzed and correlated with patients' and treatment characteristics. RESULTS: Validated questionnaire was available for 78 patients representing close to 20% of the PACA-targeted population. The majority of patients presented a T3 tumor treated with surgery (61 cases). Median follow-up for the 78 patients was 42 months and the 5-year overall survival was 51%. In the multivariate analysis, the main prognostic factors were gender (better survival in women), age ≤ 85 years, and most of all performance of surgery. CONCLUSION: Rectal cancer for patients between 79 and 85 years does not differ much from that in younger patients and can be treated in a similar manner--depending on the patient's general condition. In patients > 85 years, it is advisable to reduce surgical trauma as much as possible.

BACKGROUND: The impact of the first coronavirus disease 2019 (COVID-19) wave on cancer patient management was measured within the nationwide network of the Unicancer comprehensive cancer centers in France. PATIENTS AND METHODS: The number of patients diagnosed and treated within 17 of the 18 Unicancer centers was collected in 2020 and compared with that during the same periods between 2016 and 2019. Unicancer centers treat close to 20% of cancer patients in France yearly. The reduction in the number of patients attending the Unicancer centers was analyzed per regions and cancer types. The impact of delayed care on cancer-related deaths was calculated based on different hypotheses. RESULTS: A 6.8% decrease in patients managed within Unicancer in the first 7 months of 2020 versus 2019 was observed. This reduction reached 21% during April and May, and was not compensated in June and July, nor later until November 2020. This reduction was observed only for newly diagnosed patients, while the clinical activity for previously diagnosed patients increased by 4% similar to previous years. The reduction was more pronounced in women, in breast and prostate cancers, and for patients without metastasis. Using an estimated hazard ratio of 1.06 per month of delay in diagnosis and treatment of new patients, we calculated that the delays observed in the 5-month period from March to July 2020 may result in an excess mortality due to cancer of 1000-6000 patients in coming years. CONCLUSIONS: In this study, the delays in cancer patient management were observed only for newly diagnosed patients, more frequently in women, for breast cancer, prostate cancer, and nonmetastatic cancers. These delays may result is an excess risk of cancer-related deaths in the coming years.

BACKGROUND: Given the serious health effects of lead poisoning (Pb> or =10microg/dL), the present study was designed to estimate the time required to reach and identify factors associated with reaching Pb<10microg/dL according to the severity of the poisoning. METHODS: Since 1992, the Greater Paris lead poisoning monitoring system (SSSILF) has been systematically recording data on blood lead levels of screening and follow-up testing of children in the region. In children under the age of seven when screened positive for lead poisoning, survival curves without reaching the threshold of 10microg/dL and the relative risk (RR) of reaching this threshold were calculated (Kaplan-Meier curves and Cox model), according to blood lead level groups (Group 4: Pb> or =45microg/dL; Group 3: 25microg/dL< or =Pb<45microg/dL; Group 2: 10microg/dL< or =Pb<25microg/dL; (by definition, Group 1: Pb<100microg/L and risk factors of poisoning). RESULTS: The median survival times without reaching the threshold of Pb<10microg/dL were 72.7 months for Group 4, 36.8 months for Group 3 and 14.5 months for Group 2. Compared to reference categories, the time to Pb<10microg/dL was longer for children aged four and over at the time they screened positive for poisoning (Groups 4 and 3), for children displaying pica behavior (Groups 3 and 2), for children in an environment with another child suffering from lead poisoning (Groups 3 and 2) and for children of mothers from Sub-Saharan or North Africa countries (Group 2); the differences reached statistical significance. Changes in Pb levels were better for all children (Groups 4, 3 and 2) screened over the most recent period, i.e. 2002 to 2006, and for Group 2 children living in Paris or the nearby district of Seine-Saint-Denis. CONCLUSION: While the time required has gone down over recent years, the time to reach the threshold of Pb<10microg/dL is counted in years and varies depending on known poisoning risk factors and the district responsible for patient management. It is essential to have early lead poisoning screening for children in high-risk groups and then follow-up after rapid implementation of appropriate medical and social measures.

BACKGROUND & AIMS: Malnutrition affects 5-10% of elderly people living in the community. A few studies suggest that nutritional intervention may reduce health care costs. The present study included malnourished elderly patients living at home. It aimed to compare health care costs between patients that were prescribed ONS by their general practitioner and those who were not, and to assess the effect of ONS prescription on the risk of hospitalisation. METHODS: This prospective multicentre observational study included malnourished patients ≥70 years old who lived at home. Patients were defined as malnourished if they presented with one or more of the following criteria: weight loss ≥5% in 1 month, weight loss ≥10% in 6 months, BMI <21 kg/m2, albuminemia <35 g/L or Short-Form MNA ≤ 7. Their general practitioners prescribed an ONS, or not, according to their usual practice. Health care costs were recorded during a 6-month period. Other collected data were diseases, disability, self-perception of current health status, quality of life (QoL), nutritional status, appetite and compliance to ONS. A propensity score method was used to compare costs and risk of hospitalisation to adjust for potential confounding factors and control for selection bias. RESULTS: We analysed 191 patients. At baseline, the 133 patients (70%) who were prescribed ONS were more disabled (p < 0.001) and had poorer perception of their health (p = 0.02), lower QoL (p = 0.04) and lower appetite (p < 0.001) than the 58 patients (30%) who were not prescribed ONS. At 6 months, appetite had improved more in the ONS prescription group (p = 0.001). Weight change was not different between groups. Patients prescribed ONS were more frequently hospitalised (OR 2.518, 95% CI: [1.088; 5.829] hosp; p = 0.03). Analyses of adjusted populations revealed no differences in health care costs between groups. In the ONS prescription group, we identified that health care costs were lower (p = 0.042) in patients with an energy intake from ONS ≥ 500 kcal/d (1389 ± 264 ) vs. < 500 kcal/d (3502 ± 839 ). The risk of hospitalisation was reduced 3 and 5 times when the intake from ONS was ≥30 g of protein/day or ≥500 kcal/d, respectively. CONCLUSIONS: ONS prescription in malnourished elderly patients generated no extra heath care cost. High energy and protein intake from ONS was associated with a reduced risk of hospitalisation and health care costs.

Weight loss, together with psychological and behavioural symptoms and problems of mobility, is one of the principal manifestations of Alzheimer's disease (AD). Weight loss may be associated with protein and energy malnutrition leading to severe complications (alteration of the immune system, muscular atrophy, loss of independence). Various explanations have been proposed such as atrophy of the mesial temporal cortex, biological disturbances, or feeding behaviours; however, none has been proven. Prevention of weight loss in AD is a major issue. It requires regular follow-up and must be an integral part of the care plan. The aim of this article is to review the present state of scientific knowledge on weight loss associated with AD. We will consider four points: the natural history of weight loss, its known etiological factors, its consequences and the various management options.

The Région Languedoc Roussillon is the umbrella organisation for an interconnected and integrated project on active and healthy ageing (AHA). It covers the 3 pillars of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA): (A) Prevention and health promotion, (B) Care and cure, (C) and (D) Active and independent living of elderly people. All sub-activities (poly-pharmacy, falls prevention initiative, prevention of frailty, chronic respiratory diseases, chronic diseases with multimorbidities, chronic infectious diseases, active and independent living and disability) have been included in MACVIA-LR which has a strong political commitment and involves all stakeholders (public, private, patients, policy makers) including CARSAT-LR and the Eurobiomed cluster. It is a Reference Site of the EIP on AHA. The framework of MACVIA-LR has the vision that the prevention and management of chronic diseases is essential for the promotion of AHA and for the reduction of handicap. The main objectives of MACVIA-LR are: (i) to develop innovative solutions for a network of Living labs in order to reduce avoidable hospitalisations and loss of autonomy while improving quality of life, (ii) to disseminate the innovation. The three years of MACVIA-LR activities are reported in this paper.

OBJECTIVES: Weight loss and malnutrition are frequent and serious complications of Alzheimer's disease. The aim of the present article was to describe the cognitive and behavioural characteristics of the test population within the frame of the PHRC REAL.FR cohort (for Réseau sur la Maladie d'Alzheimer Français), depending on their nutritional state, and to consider their evolution one year after the original inclusion. METHOD: The study population' stratification was done in three groups according to their Mini Nutritional Assessment (MNA) score: malnutrition group (MNA < 17.5), at risk of malnutrition group (MNA 17.5-23.5), and normal nutritional status group (MNA > or = 23.5). 561 patients were evaluated at inclusion time, 393 at one year. The evaluation included the following scales: Mini Nutritional Assessment (MNA), Mini Mental State Examination (MMSE), Activities Daily Living (ADL), Instrumental Activities Daily Living (IADL), Neuro Psychiatric Inventory (NPI) and Zarit scale (ZARIT). Comparison and descriptive analysis for each MNA group at baseline and at one year has been performed. RESULTS: at baseline, the well-nourished and the malnutrition risk groups are significantly different concerning age, IADL and NPI; the well-nourished and undernutrition groups are different concerning MMSE, NPI and Zarit; the malnutrition risk and undernutrition groups are only different concerning NPI. At one year, the well-nourished and the malnutrition risk and undernutrition groups are different concerning one lonely variable, the NPI, in a significant way. The comparison of the three groups between baseline and one-year evaluation demonstrate for the well-nourished group an aggravation of MMSE, ADL, IADL, NPI, for the malnutrition risk group of MMSE and IADL, and for the undernutrition group of MMSE, IADL and NPI. CONCLUSION: Among the patients suffering from Alzheimer's disease, the most malnutritioned worsen highly on cognitive and functional capacities. Furthermore, the nutritional aggravation seems strongly linked to behavioural disorders aggravation. The improvement of those disorders has therefore to be part of every improvement strategy applied to the nutritional status of the demented patients.

Behavioral and Psychological Symptoms are major and frequent manifestations of Alzheimer's Disease (AD). The aim of the present study was to evaluate neuropsychiatric symptoms in the PHRC REAL.FR cohort (for Réseau sur la maladie d'Alzheimer Français) after one year of evolution. Four hundred and eighty two patients with mild and moderate AD were assessed. A majority of them had significant symptoms at inclusion (85.3 % of subjects with mild AD, 89.7% of patients with a moderate AD). Patients with mild AD had a significant increase of the Neuropsychiatric Inventory (NPI) frequency x severity scores for apathy and aberrant motor behavior. Patients with moderate AD had a significant increase of NPI disinhibition, aberrant motor behavior and sleep disorders scores. The variation of NPI total score at one year correlated positively with change in Zarit's caregiver burden score, independently of global cognitive evolution. After one year, a group of 54 patients were institutionalized in nursing home or long term care unit. When compared to non institutionalized patients, the institutionalized group was characterized at base line by a lower MMSE score, a higher Zarit caregiver burden score, and a higher NPI agitation and disinhibition scores.

Frailty is a geriatric syndrome that predicts disability, morbidity and mortality in the elderly. Poor nutritional status is one of the main risk factors for frailty. Macronutrients and micronutrients deficiencies are associated with frailty. Recent studies suggest that improving nutritional status for macronutrients and micronutrients may reduce the risk of frailty. Specific diets such as the Mediterranean diet rich in anti-oxidants, is currently investigated in the prevention of frailty. The aim of this paper is to summarize the current body of knowledge on the relations between nutrition and frailty, and provide recommendations for future nutritional research on the field of frailty.

INTRODUCTION: Cobalamin deficiency is frequent in elderly patients and the main aetiologies are food-cobalamin malabsorption and pernicious anaemia. The aim of our retrospective study was to identify the causes and methods of management of cobalamin deficiency at Nice geriatric university hospital. METHODS: A retrospective monocentric study was conducted over 14 months at Nice geriatric hospital, which included patients with cobalamin deficiency having received supplementation. The clinical and paraclinical data, etiological diagnosis, treatment and follow-up modalities were analyzed retrospectively. RESULTS: We studied 125 elderly patients whose median age was 85.5 ± 7 years. The etiological diagnosis was food-cobalamin malabsorption for 72 patients (57.6 %), nutritional cobalamin deficiency for 15 patients (12 %), pernicious anaemia for 12 patients (9.6 %) and there was no etiological diagnosis for 26 patients (20.8 %). Concerning cobalamin therapy, 111 patients (88.8 %) received oral therapy and 14 (11.2 %) intramuscular therapy. Vitamin B12 levels increased significantly after supplementation (p<0.001) but cobalamin administration varied according to the diagnoses (p<0.001) and was less effective in patients with dementia (p=0.04) and food-cobalamin malabsorption. CONCLUSION: Our study showed the importance of food-cobalamin malabsorption in etiological diagnosis in accordance with the literature, but also the non-negligible share of nutritional cobalamin deficiency. Mainly oral cobalamin supplementation was used in our study with a significant increase in vitamin B12 levels. An oral cobalamin regimen is proposed for elderly patients with cobalamin deficiency but with no severe neurological signs.

BACKGROUND AND PURPOSE: Musculoskeletal system deterioration among the aging is a major reason for loss of autonomy and directly affects the quality of life of the elderly. Articular evaluation is part of physiotherapeutic assessment and helps in establishing a precise diagnosis and deciding appropriate therapy. Reference instruments are valid but not easy to use for some joints. The main goal of our study was to determine reliability and intertester reproducibility of the MP-BV, an inertial sensor (the MotionPod(®) [MP]) combined with specific software (BioVal [BV]), for elbow passive range-of-motion measurements in geriatrics. METHODS: This open, monocentric, randomized study compared inertial sensor to inclinometer in patients hospitalized in an acute, post-acute, and long-term-care gerontology unit. RESULTS: Seventy-seven patients (mean age 83.5±6.4 years, sex ratio 1.08 [male/female]) were analyzed. The MP-BV was reliable for each of the three measurements (flexion, pronation, and supination) for 24.3% (CI 95% 13.9-32.8) of the patients. Separately, the percentages of reliable measures were 59.7% (49.2-70.5) for flexion, 68.8% (58.4-79.5) for pronation, and 62.3% (51.2-73.1) for supination. The intraclass correlation coefficients were 0.15 (0.07-0.73), 0.46 (0.27-0.98), and 0.50 (0.31-40 0.98) for flexion, pronation, and supination, respectively. CONCLUSION: This study shows the convenience of the MP-BV in terms of ease of use and of export of measured data. However, this instrument seems less reliable and valuable compared to the reference instruments used to measure elbow range of motion in gerontology.

We report a prospective quantitative image analysis study of C cells in 57 normal autopsy thyroid glands, serially sectioned and wholly embedded in paraffin; all slides were immunohistochemically stained for calcitonin. Computerized quantitative image analysis was performed on 47 cases to measure C cell surface area and parenchymatous surface area after immunoperoxidase staining for calcitonin. The method was time-effective, with a good reproducibility. C cells were mainly found in the middle third of each lobe. Important inter-individual variations were observed; the maximum C cell surface area in a section (Amax) ranged from 28 x 10(3) to 470 x 10(3) microns2 (mean, 167 x 10(3) microns2) among 42 adults. Of particular interest was the important difference observed between sexes; Amax was twice as high in men (mean, 201 x 10(3) microns2) as in women (mean, 91 x 10(3) microns2; P = 0.0009). Moreover, 14 (33%) adult subjects [2 women (15%) and 12 men (41%)] fulfilled C cell hyperplasia criteria, i.e. at least 3 fields at x 100 magnification containing more than 50 C cells, suggesting that a substantial part of the normal adult population could have C cell hyperplasia.

Thirty-eight patients (25 women, 13 men; mean age, 57.8 [32 to 91]) showing one or more medullary thyroid microcarcinomas (ie, < 1 cm), with no prior MEN II or medullary thyroid carcinoma history in their family, were reviewed. Follow-up was available for 29 patients (mean, 53.6 months [1 to 147]). 21 patients (72.4%) are alive and free of disease, four patients (13.8%) died during follow-up without disease, 2 patients are alive with disease (local recurrence and persistent hypercalcitoninemia) after 80 and 99 months, respectively, and 2 patients died of disease after 24 and 46 months. Most tumors were incidental pathological findings (19 of 38) or were discovered by systematic blood calcitonin measurement for a nodular thyroid disease (15 of 38). Only the four patients who had an unfavorable outcome were symptomatic cases (palpable micro-MTC, diarrhea, cervical lymph node metastasis and pulmonary metastatic disease). The two patients with metastatic disease at diagnosis died during follow-up. In univariate analysis, a symptomatic medullary thyroid carcinoma was a strong predictor of an unfavourable outcome (p < .00008), as were the preoperative calcitonin level (P = .007) and an elevated postoperative calcitonin level (P = .004). Among 30 histopathological criteria, only the presence of amyloid correlated with an unfavorable outcome (P = .018).

Five studies comparing metastatic patterns of lobular and ductal carcinoma have reported conflicting results. These results are based on the evaluation of heterogeneous groups, without taking clinical differences into account. The aim of this clinical study is to compare metastatic patterns of matched ductal and lobular carcinomas. One hundred eighty-eight lobular carcinomas were matched with 188 ductal carcinomas who showed identical ages, menopausal status, TNM, and dates of treatment. Hepatic, lung and brain metastases are more frequent in ductal carcinoma. Metastases to the gastrointestinal system, gynecologic organs, and peritoneum are more characteristic of lobular carcinoma. Life table analysis of overall and disease free survival shows no significant differences. The metastatic patterns of ductal and lobular carcinomas are different, and physicians should be aware that the classical staging of the breast cancer is not fit to lobular carcinoma. fit to lobular carcinoma. Could we define patients presenting high metastatic risks? Could we use CA. 125, sonography, laparoscopy in the staging? Should we change the whole therapeutic approach of lobular carcinoma?

Elderly patients are often considered as subjects at risk for bad tolerance to chemotherapy. They are therefore treated in a less aggressive way compared with younger women. In a retrospective study, we evaluated the dose-intensity of a chemotherapy for 15 patients older than 70 years of age, presenting an ovarian carcinoma. Median age was 73 years. All but one were classified in stage III-IV and only four were presented with a complete surgery or with a pathological residue < 2 cm. Six patients were considered as non operable. Performance status (PS) was in 11 cases equal to 0 or 1. The treatment associated from D1 to D4: carboplatine 75 mg/sqm/day, cyclophosphamide 250 mg/sqm/day, etoposide 50 mg/sqm/day for six cycles each over four weeks. We compared for each drug the delivered dose-intensity (DID) all along the six cycles to the forecast dose-intensity (FID). Except for the patients with a PS > or = 2, treated in first intention by a 2/3 dose, the DID/FID ratio was > 90%. It decreased between the 1st and 3rd cycles, then remained unchanged. Treatment was well tolerated by patients with a PS < 2 whose 4/11 have presented a grade III-IV hematologic toxicity. In return, despite the initial dose reduction, 3/4 patients with a PS > or = 2 had severe complications. There were no toxic deaths. Three patients only had a delay for reinduction. Three out of six non operables at first had a surgical second-look with possibility of residual masses cutting of (3 PRh). Four patients were alive in first CR at 18, 22, 23 and 28 months. Women older than 70 years with a good performance status presenting an ovarian carcinoma can be treated as younger women are. A chemotherapy using efficient drugs can be delivered with an acceptable toxicity and a high dose-intensity.

Carcinoma of unknown primary site has been defined as a metastatic disease without known primary site (upon clinical, radiological or endoscopic examination) at the initial therapeutic decision. The incidence of such carcinomas is between 1.6 and 15% of all adult's tumors. The goals of this retrospective and monocentric study were 1) the incidence of these carcinoma; 2) the utility to identify the primary site; 3) the efficacy of treatment in terms of survival; and 4) the prognostic factors to optimize strategic choices. Between January 1980 to December 1995, 311 cases were identified; this represents 1.6% of all cases treated in our center. Histological analyses of metastases revealed adenocarcinoma: 164 cases (92 males, 72 females; 29 well differentiated, 11 poorly differentiated and 41 undifferentiated); squamous cell carcinoma: 90 cases (78 males, 12 females); undifferentiated carcinoma: 27 cases (21 males, 6 females); neuro-endocrine tumor: 10 cases; and others: 20 cases. Median age was 61.1 years (30-94). Half of the patients had a PS between 0 and 1. The carcinoma was revealed by only one site of metastases in 35% of the cases (lymph node 72.9%, bone 35.5%, liver 19.4% and lung 16.5%). The primary carcinoma was found in only 6% of the cases. Median survival of all patients was only 9 months. Multivariate analyses by the Cox method show four positive prognostic factors: sex (female), performance status (PS < 2), histological analyses (squamous cell carcinoma), only one site of metastases.
