[Epidemiology of prostate cancer (PCa) in French Guyana (FG) - Preliminary results]. / Épidémiologie du cancer de la prostate en Guyane française ­ Données préliminaires.

INTRODUCTION: Epidemiology of prostate cancer (PCa) in French Guyana (FG) is not well documented yet. It differs from the reported one in French West Indies due to a younger population, less exposed to agricultural pesticides with also much lower level of medical information and care. MATERIAL: The incidence and mortality rates available in the regional register of cancers are reported for the period 2010-2014. The characteristics of 242 consecutive prostate biopsy series performed between 2017 January and 2019 October for abnormal digital rectal examination (DRE) and/or PSA>4ng/mL are also described. RESULTS: PCa incidence in FG is 94.4°/°°°° and specific mortality 16.9°/°°°°. Among the biopsies, 77.7% (188/242) are positive with a mean PSA of 72.6ng/mL (1-4000) at a mean age of 66years (50-89), 34% (64/188) with an abnormal DRE, 12.3% (23/188) with a PSA>50ng/mL and 28.2% (53/188) with a Gleason score≥8. CONCLUSION: In spite of young population, less exposure to environmental risk factors and high rate of racial mixing, the early PCa diagnosis is still a challenge in FG. The observed incidence and mortality rates suggest underestimation of PCa cases and too late specific care what is also suggested by adverse pathological and biological characteristics of the tumors at the time of diagnosis.

Bilateral nevus comedonicus of the eyelids: An unusual cause of ptosis and ectropion.

PURPOSE: Nevus comedonicus is a rare developmental abnormality of the infundibulum of the hair follicle. OBSERVATION: We report here an unusual case of bilateral extensive nevus comedonicus of the eyelids complicated by bilateral ptosis and ectropion of the lower eyelids. Blepharoplasty was performed on both upper eyelids. Histopathological findings on skin biopsy typically show large, grouped, dilated follicular ostia filled with keratin. CONCLUSIONS AND IMPORTANCE: This case is unusual as regards the late-onset (lesions first appeared at age 35) and location of the nevus comedonicus on both eyelids.

[Does the delay from prostate biopsy to radical prostatectomy influence the risk of biochemical recurrence?] / Le delai entre biopsies de prostate et prostatectomie radicale influence-t-il le risque de recidive ?

INTRODUCTION: The influence of the delay between prostate biopsy and radical prostatectomy for patients with localized prostate cancer is controversial. The objective of this study was to establish a time limit between prostate biopsy and radical prostatectomy beyond which the risks of upgradging and biochemical recurrence (BCR) are increased. MATERIAL AND METHODS: Between January 2013 and January 2017, a retrospective analysis of the clinical, biological and histological data of 513 patients treated with radical prostatectomy for localized prostate cancer was performed in a single center. The primary endpoint was the assessment of the risk of BCR by the difference between post-biopsy USCF-CAPRA and post-surgical CAPRA-S scores. The secondary endpoint was the evaluation of the upgrading by the difference between the Gleason score on biopsy and on surgical specimen. The risks of BCR and upgrading were compared by Student test according to different delays between prostate biopsy and radical prostatectomy. The shortest delays for which a significant difference was found were reported. RESULTS: In this study, 513 patients were included. The median age at the time of the biopsy was 65 years (IQR: 60-69). The median preoperative PSA was 7.30ng/mL (IQR: 5.60-9.94). The median time between biopsy and surgery was 108 days (IQR: 86-141). For the entire cohort, the risk of BCR was significantly higher above a threshold of 90 days (P=0.039). No threshold was found for Gleason 6(3+3) patients. A 90-day threshold was found for Gleason 7(3+4) patients (P=0.038). Gleason patients≥8 had more upgrading beyond a 60-day threshold (P=0.040). CONCLUSION: Our study showed that after a 3 months delay, the risk of BCR was significantly higher for localized prostate cancer. It seemed possible to extend this period for low-risk patients, whereas it seemed necessary to keep it for intermediate-risks and to reduce it to 2 months for high-risks. LEVEL OF EVIDENCE: 4.

High prevalence of HPV infection in the remote villages of French Guiana: an epidemiological study.

Cervical cancer is the second most frequent cancer in women in French Guiana. Studies have shown that populations living in the remote areas of the interior have early sexual debut and that multiple sexual partnerships are common. The objective of the present study was thus to determine the prevalence of human papillomavirus (HPV) infection in these areas. A study was conducted in women aged 20-65 years with previous sexual activity. Women were included on a voluntary basis after using local media and leaders to inform them of the visit of the team. HPV infection was defined by the detection of HPV DNA using the Greiner Bio-One kit. In addition to HPV testing cytology was performed. The overall age-standardized prevalence rate was 35%. There was a U-shaped evolution of HPV prevalence by age with women aged >50 years at highest risk for HPV, followed by the 20-29 years group. Twenty-seven percent of women with a positive HPV test had normal cytology. Given the high incidence of cervical cancer in French Guiana and the high prevalence of HPV infections the present results re-emphasize the need for screening for cervical cancer in these remote areas. Vaccination against HPV, preferably with a nonavalent vaccine, also seems an important prevention measure. However, in this region where a large portion of the population has no health insurance, this still represents a challenge.

[Analysis and prognostic factors of the specimen of radical prostatectomy in prostate cancer]. / Analyse et facteurs pronostiques de la pièce opératoire après prostatectomie totale pour cancer de la prostate.

OBJECTIVES: Handling and pathologic analysis of radical prostatectomy specimens are crucial to confirm the diagnosis of prostate cancer and evaluate prognostic criteria. MATERIAL AND METHODS: A systematic review of the scientific literature was performed in the Medline database (PubMed), using different associations of the following keywords: prostate cancer; prostatectomy; specimen; handling; pathology; tumor staging; Gleason score; surgical margin; prognosis; frozen section; lymph node; biomarkers. A particular search was done on specimen management and characterization of tissue prognostic factors. RESULTS: Handling of both radical prostatectomy specimen and lymph node dissection is standardized according to international criteria. Although the main histoprognostic factors are still Gleason score, pathologic staging and margin status, these criteria have been refined these last 10 years, allowing to improve the prediction of relapse after surgical treatment. CONCLUSION: The standardization of handling and pathology reporting of radical prostatectomy specimens will be mandatory for treatment uniformization according to risk stratification in prostate cancer and personalization of therapeutic approaches.

Preoperative low serum testosterone is associated with high-grade prostate cancer and an increased Gleason score upgrading.

BACKGROUND: To compare histological feature of prostate cancer (PCa) according androgenic status in patients who underwent radical prostatectomy (RP). METHODS: Between March 2007 and September 2013, we prospectively analysed 937 patients who were referred to our centre for RP. Clinical, pathological and biological data have been prospectively collected. Preoperative total testosterone (TT) and bioavailable testosterone (BT) serum determinations were carried out. The threshold for low serum testosterone was set at TT<3 ng/ml. Preoperative PSA value was registered. Gleason score (GS) and predominant Gleason pattern were determined in prostate biopsies and in prostate tissue specimens, crosschecked by two uro-pathologists. RESULTS: Nine hundred and thirty-seven consecutive patients were included. In all, 14.9% patients had low TT in the population. An exact match between biopsy and prostate specimens in GS grading was observed for 50.6% patients (n=474). Also, 40.9% of all patients were upgraded (n=383): 45.3% (n=63) in low serum testosterone patients and 40.1% (n=320) in normal serum testosterone patients. For prostate specimens, the proportion of patients with predominant Gleason pattern 4 was higher in patients with low TT compared with normal TT (41.7% vs 29.1%, P=0.0029). In all, 20.1% were upgraded from predominant Gleason pattern 3 on biopsies specimen to predominant Gleason 4 pattern on the prostate specimen in patients with low TT, whereas 11.6% were upgraded for normal TT patients (P=0.002). CONCLUSIONS: Low serum testosterone is an independent risk factor for predominant Gleason pattern 4 on prostate specimen after RP and for upgrading from low- to high-grade cancer between prostate needle biopsies and RP specimen. This observation should be taken into account in localised PCa management, especially for active surveillance or when a nerve-sparing approach is considered.

[Pyoderma gangrenosum and neutrophilic aortitis preceding the development of rheumatoid arthritis]. / Pyoderma gangrenosum et aortite neutrophilique précédant l'apparition d'une polyarthrite rhumatoïde.

BACKGROUND: We report a case of pyoderma gangrenosum (PG) associated with a complication comprising ascending aortic dissection (neutrophilic aortitis) in a setting of rheumatoid arthritis (RA). PATIENTS AND METHODS: A 79-year-old female patient was hospitalized in late 2009 for vegetating PG. Treatment with general steroids followed by colchicine and topical steroids resulted in complete healing of skin lesions. During hospitalization, the patient presented dissection of the ascending part of the aorta, for which emergency surgery proved effective. Histological examination of the excised tissue revealed diffuse neutrophilic aortitis. Diagnoses of Takayashu's disease and of lupus were ruled out. A chest CT scan showed interstitial lung disease with mild lymphocytosis in the bronchoalveolar fluid, but with no isolated pathogenic organisms. Relapse of skin lesions occurred 3 and 4 years later, associated with the development of RA, and worsening of the interstitial lung disease was noted in a scan carried out it in 2013, following which stabilization was observed in April 2014. There was no recurrence of the PG lesions. CONCLUSION: To our knowledge, no other cases involving association of neutrophilic aortitis with PG and RA has been published to date. The literature describes the emergence of the concept of systemic neutrophilic dermatoses, and this notion is reinforced by the presence of a cutaneous and aortic site of the neutrophilic disease in a single patient.

'Green Apple' Heart Failure.

We report here the clinical case of an Afro-Caribbean patient referred for complete atrioventricular block for whom a diagnosis of hereditary cardiac amyloidosis was eventually confirmed. Hereditary cardiac amyloidosis is an emerging threat in the Caribbean, and the main goal of this report is to raise the awareness of the disease among physicians.

Imaging of intestinal involvement in endometriosis.

Deep gastrointestinal involvement in endometriosis is characterised by fibrous, retractile thickening of the intestinal wall. The most common location is the upper rectum, in contiguity with a lesion of the torus uterinus. As part of a preoperative assessment, it is essential to establish an accurate and exhaustive map of intestinal lesions so that the surgeon can plan his actions. Transvaginal sonography and MRI correctly analyse pelvic and rectal involvement. Given the frequency of multiple intestinal sites, particularly sigmoid and associated ileo-caecal lesions, water enema CT should be performed. The role of rectal endoscopic sonography is debated.

[CCAFU Recommendations 2013: Prostate cancer]. / Recommandations en onco-urologie 2013 du CCAFU : Cancer de la prostate.

INTRODUCTION: The sub Comittee prostate of the CCAFU established guidelines for diagnostic, treatment, evaluation and standart of care of prostate cancer. METHODS: Guidelines 2010 were updated based on systematic literature search performed by the sub-Comittee in Medline and PubMed databases to evaluate references, levels of evidence and grade of recommandation. RESULTS: Pathological examination of the tissue specimens was defined specifically for Gleason score according to ISP 2005 recommandations. Prostate and pelvis RMN became the reference in terms of radiological exam. Individual and early diagnosis of prostate cancer was defined and role of PSA was precised. Active surveillance became one of the standart of care of low-risk tumors, radical prostatectomy remained one of the options for all risk group tumors, length of hormonotherapy in association with radiotherapy was precised according to the risk group. Side effects of hormonotherapy treament needed specific supervision ; hormonotherapy had no indication in case of non metastatic tumors and intermittent hormonotherapy in metastatic tumors. New hormonal drugs in pre and post chemotherapy and bone target drugs opened new therapeutics pathways. CONCLUSION: From 2010 to 2013, standarts of care of prostate cancer were modified because of results of prospective studies and new therapeutics. They allowed precise treatments for each specific clinical situation. In the future, multidisciplinary treatments for high risk tumors, time of adjuvant treatment and sequencies of new hormonal treatment had to be defined.

[Extemporaneous examination in lung pathology: the pathologist's view]. / L'examen extemporané en pathologie thoracique. Le point de vue du pathologiste.

Extemporaneous examination of a thoracopulmonary lesion has an unquestionable interest when pre-surgical diagnostic workup has not allowed determining its exact nature. This examination, the sole objective of which is to guide the surgical approach, is especially important in lung pathology, due to the limited non-surgical access to thoracic lesions and the morbidity and mortality of repeated surgery. Its yield as a decision-making procedure is of utmost importance in many clinical situations, and a close collaboration between thoracic surgeons and pathologists is required to ensure its quality, in a context of mutual confidence that requires time and experience. After a presentation of the indications and practical modalities of extemporaneous examination, we will underline its limitations and insist on difficult situations for the pathologist and inadequate indications.

[New concepts in the management of MIBC in 2010]. / Actualités concernant la prise en charge et le suivi des tumeurs vésicales infiltrant le muscle (TVIM) en 2010.

The urothelial carcinoma of the prostate is an entity which is necessary to recognize. The infiltration of the prostatic stroma is a major prognostic factor. The 2009 pTNM classification distinguish carcinoma in situ of the urethra with involvement of prostatic acini (pT2) from direct invasion of prostatic stroma through outside involvement (pT4). In case of non metastatic muscle invasive bladder cancer with major lymphatic invasion, the standard treatment remains neoadjuvant chemotherapy followed by radical cystectomy and extended lymphadenectomy. Only some patients can hope a complete response after neoadjuvant chemotherapy. For these responders, we can sometimes discuss, at an individual level, a bladder conservative strategy with an intensive surveillance.
