Abstract
The objective was to evaluate the available published data on sinonasal melanoma and analyse its clinical features, treatment modalities, and prognostic factors. An electronic search was undertaken in March 2018 in multiple databases. Eligibility criteria included publications with sufficient clinical, histological, and immunohistochemical information to confirm the diagnosis. Seventy-three publications (439 cases) were included. The lesion was more prevalent in females than in males. There was a higher prevalence in the seventh and eighth decades of life. The lesions mainly presented as epistaxis and commonly involved the nasal cavity. Age (>67.6 years; P=0.0012), primary location (middle turbinate; P=0.0112), disease stage (advanced disease stage; P=0.0026), treatment (radiotherapy; P=0.0111), recurrence (recurrence presented; P=0.0137), and distant metastasis (distant metastasis presented; P=0.0011) were independently associated with a lower survival rate. Recurrence was significantly correlated with age (>67.6 years; P=0.0021), sex (males tended to present a higher recurrence rate than females; P=0.0051), disease stage (stages III and IV presented a higher recurrence rate than stages I and II; P=0.0331), and histological type (amelanotic lesions presented a higher index of recurrence than melanotic lesions; P=0.0095). In conclusion, sinonasal melanoma is a neoplasm with a poor prognosis, presenting a 30.69% possibility of survival after 5 years.

Abstract
The objective was to integrate the available published data on chondrosarcoma (CHS) of the jaw bones into a comprehensive analysis of its clinical and histological features, treatment, and prognostic factors. An electronic search was undertaken in October 2017. To be eligible, the publication had to provide sufficient clinical/histological data to confirm the diagnosis. One hundred and ten publications (224 cases of CHS) were identified and included. There was a slightly higher prevalence of CHS in males than in females. Most subjects with CHS were in the second to fifth decades of life. The most common symptom was swelling and the most commonly observed location was the maxilla. Histologically, most tumours were of the conventional type and were low grade tumours. The treatment of choice was tumour resection. Histological grade, treatment with chemotherapy alone, and the presentation of recurrence or metastasis were found to be significant independent prognostic factors: patients who presented high-grade tumours, who received chemotherapy alone as the treatment of choice, and those who presented recurrence or metastasis were more likely to have a worse prognosis. In addition, radical surgery associated with radiotherapy as the treatment protocol showed a better prognosis.

Abstract
OBJECTIVE To describe the clinical and genetic features of patients with cherubism. MATERIAL AND METHODS A descriptive analysis of 14 cases from nine different families was carried out. Clinicopathological, imaging, and follow-up data were retrieved from patients' medical files and correlated with the genetic profile of each patient. Genomic DNA isolated from buccal mucosa cells was subjected to direct sequencing analysis of the SH3BP2 gene. RESULTS Females were more affected than males (8:6), and the mean age at diagnosis was 8.6 years (range 3-30 years). Eleven patients exhibited simultaneous bilateral involvement of the maxilla and mandible. Two patients did not have a familial history of cherubism. Progressive growth pattern was found in six patients and stable lesions were observed in other seven patients, whereas in one patient, complete spontaneous remission was documented during the follow-up (31 years). Mutations were found in 13 cases and included the typical heterozygous missense mutations R415Q, P418T, and P418H at exon 9 of SH3BP2. No correlation between the mutations and the clinical manifestations was observed. CONCLUSION Three different point mutations in the SH3BP2 gene were detected with variable clinical involvement. Genotype-phenotype association studies in larger population with cherubism are necessary to provide important knowledge about molecular mechanisms related to the disease.

Abstract
Granulomatosis with polyangiitis (GPA) is a potentially lethal disease characterized by systemic necrotizing vasculitis, which affects small- and medium-sized blood vessels and is often associated with serum cytoplasmic antineutrophil cytoplasmic antibody. The upper and lower respiratory tract and kidney are the most involved sites, but oral lesions can be identified in 6-13% of the cases, whereas in only 2% of the cases, oral manifestations represent the first signal of the disease usually as gingival swellings or unspecific ulcerations. Without treatment, the mainstay of which is the combination of immunosuppressants and systemic corticosteroids, GPA may run a fatal course. In this report we describe an original case of GPA affecting a 75-year-old female patient referred to our service due to a gingival swelling with 3-month duration. Although the patient was correctly diagnosed and promptly treated, she died 3 months after the initial diagnosis.

Abstract
Although several histopathological parameters and grading systems have been described as predictive of the treatment response and outcome of oral squamous cell carcinoma (OSCC), none is universally accepted. A new scoring system, the histological risk model, was recently described to be a powerful predictive tool for recurrence and overall survival in OSCC. The aim of this study was to verify the predictive role of the histological risk model in a cohort of 202 patients at all stages of oral/mobile tongue squamous cell carcinoma (OTSCC). Demographic and clinical data were collected from the medical records and the tumours were evaluated using the histological risk model. Statistical analyses were performed using the χ(2) test, the Kaplan-Meier method, and the Cox regression model. The histological risk model showed no statistical correlation with demographic or clinical parameters and did not Predict the outcome of the OTSCC patients. However, multivariate regression analysis revealed a significant correlation of the clinical disease stage with the disease outcome. Despite major efforts to identify new predictive parameters and histological systems, clinical features are still the most reliable prognostic factors for patients with OTSCC.

Abstract
Thrombospondin 2 (TSP2) is a protein with important roles in different tumor types, mainly related to tumor inhibition. However, there are limiting data regarding TSP2 in prostate cancer (PCa) and benign prostatic hyperplasia (BPH). We aimed to investigate TSP2 transcript and protein expression in tumoral and non-tumoral prostate tissues and cell lines, and its implications for PCa diagnosis and progression. TSP2 transcript expression was evaluated by real time PCR in PCa and BPH tissue samples and in tumoral and non-tumoral cell lines. TSP2 protein expression analysis was conducted by immunohistochemistry in a tissue microarray (TMA) containing PCa and BPH tissue samples. TSP2 transcript was down-regulated in PCa tissue samples and cell lines, when compared to BPH and non-tumoral samples (P<0.01). Receiver Operating Curve (ROC) analysis demonstrated that TSP2 transcript levels can better distinguish PCa from BPH tissue samples (P<0.01) than serum PSA levels (P=0.299). TSP2 protein expression has been observed in the cytoplasm of both PCa and BPH epithelial and stromal compartments. TSP2 stromal staining scores were significantly lower in PCa than in BPH tissues (P<0.01), while similar TSP2 epithelial staining patterns were observed in both diseases. Notably, the TSP2 epithelial staining score was significantly correlated to vascular invasion and biochemical recurrence in PCa tissue samples (P<0.05). Our data indicate that TSP2 is down-regulated at PCa tissues and cell lines, especially at stroma compartment, which could be related to PCa progression. TSP2 levels could potentially be applied for differential PCa and BPH diagnosis.

Abstract
109 Background: Radical prostatectomy (RP) is the treatment of choice for patients with localized prostate cancer (PC). Previously, surgery was applied to patients with good clinical condition and aged <=70 years. Lately, with a better understanding of surgical technique, many centers have been performing RP in patients older than 70. Methods: The main objective of this cohort study is to evaluate clinical evolution according to localized PC submitted to RP in patients in extreme ages. We analysed age, PSA, ASA classification,pathological stages, Gleason scores, urinary continence, D'Amico risk classification (group 1:low; 2:intermediate; 3:high), biochemical recurrence and clinical progression. Descriptive analysis of the population was performed. Fisher's exact test or chi-square tests were used to evaluate association between clinicopathologic characteristics.Biochemical recurrence was defined by PSA more than 0.2 ng/mL post-RP. Results: In 262 patients, mean age was 63.4 years (SD 12.4; range: 41 to 83). In D'Amico's group 1 there were 96 patients (37.2%) with<=50 year old, and group 2 had 162 patients (62.8%) with age >=70. The mean follow-up in group 1 was 55.9 months (SD 41.7) and group 2 was 53.6 (SD 41.4), p=0.6770. Biochemical relapse occurred in 21 patients (15.44%) in D'Amico risk group 1, 27 (36.99%) in group 2 and 29 (59.18%) in group 3 (p<0.001). There was no difference among all the pathological variables evaluated (p>0.05). Clinical progression occurred in 2 patients (1.47%) in D'Amico risk group 1, in 3 patients (4.11%) in group 2 and in 3 patients (6.11%) in group 3 (p=0.230). There was no significant difference in relation to time to biochemical recurrence, as well as biochemical relapse rate and progression of this disease among the groups. Younger patients (in group 1) recovered earlier from urinary incontinence, as well as most were continent in final follow-up. Conclusions: Based on our results, the differences in younger or more aged patients with PC are not related to pathological variables, or rates of biochemical recurrence and clinical disease, but better preoperative clinical features and better recovery of urinary continence are seen in younger patients. No significant financial relationships to disclose.

Abstract
Acute stress promotes transient elevation of blood pressure, but there is no consistent evidence that this effect results in hypertension. In this systematic review of cohort and case-control studies that investigated the association between psychosocial stress and hypertension, we conducted a complete search up to February 2007 in MEDLINE, EMBASE, PSYCINFO and LILACS, through a search strategy that included eight terms to describe the exposure, six related to the design of the studies and one term for outcome. The quality was assessed by the Newcastle-Ottawa Quality Assessment Scale. The selection was done in duplicate by two teams of independent reviewers. Among 82 studies selected in the second phase, only 14 (10 cohort studies and 4 case-control studies), totalling 52,049 individuals, fulfilled the selection criteria. The average quality of the studies was 6.6+/-1.3 in a 9-point scale. Acute life events were associated with hypertension in one and were not associated in two studies. Five out of seven studies found a significant and positive association between measures of chronic stress and hypertension, with risk ratios ranging from 0.8 to 11.1. Three out of five studies reported high and significant risks of affective response to stress for hypertension, one a significant risk close to a unit and one reported absence of risk. Acute stress is probably not a risk factor for hypertension. Chronic stress and particularly the non-adaptive response to stress are more likely causes of sustained elevation of blood pressure. Studies with better quality are warranted.

Abstract
This study examines the clinical impact of PTEN genomic deletions using fluorescence in situ hybridisation (FISH) analysis of 107 prostate cancers, with follow-up information covering a period of up to 10 years. Tissue microarray analysis using interphase FISH indicated that hemizygous PTEN losses were present in 42/107 (39%) of prostatic adenocarcinomas, with a homozygous PTEN deletion observed in 5/107 (5%) tumours. FISH analysis using closely linked probes centromeric and telomeric to the PTEN indicated that subband microdeletions accounted for ∼70% genomic losses. Kaplan–Meier survival analysis of PTEN genomic losses (hemizygous and homozygous deletion vs not deleted) identified subgroups with different prognosis based on their time to biochemical relapse after surgery, and demonstrated significant association between PTEN deletion and an earlier onset of disease recurrence (as determined by prostate-specific antigen levels). Homozygous PTEN deletion was associated with a much earlier onset of biochemical recurrence (P=0.002). Furthermore, PTEN loss at the time of prostatectomy correlated with clinical parameters of more advanced disease, such as extraprostatic extension and seminal vesicle invasion. Collectively, our data indicates that haploinsufficiency or PTEN genomic loss is an indicator of more advanced disease at surgery, and is predictive of a shorter time to biochemical recurrence of disease.

Abstract
PURPOSE The major issue in penile cancer is deciding who should or should not undergo lymph node dissection. Clinical and invasive methods are not reliable for staging. Clinical and pathological factors involved in lymph node metastases and prognosis were evaluated in 145 patients with penile carcinoma staged according to the 1978 TNM system, and treated with amputation and lymphadenectomy. MATERIALS AND METHODS Clinical factors studied were patient age, race, disease evolution time, symptoms, and clinical T and N stages. Pathological factors of the primary tumor considered were tumor thickness, histological grade, lymphatic and venous embolization, infiltration of the corpora cavernosa, corpus spongiosum and urethra, mononuclear and eosinophilic infiltrates, and cell alterations suggestive of human papillomavirus. All slides were reviewed by 1 pathologist. The Cox regression hazards method for multifactorial analysis was used. RESULTS Followup ranged from 0.7 to 453.2 months (mean 85.8, median 32.7). The 5-year disease-free and overall survival rates were 45.3 and 54.3%, respectively. Venous and lymphatic embolizations were the main factors affecting significantly the incidence of lymph node metastasis, which were the main risks factors for recurrence and death. Pathologically proved infiltration of the corpora cavernosa, urethra and adjacent structures, which corresponded to stages T2, T3 and T4 disease, respectively, of the current TNM classification, were not significant predictors for incidence of lymph node metastasis, disease-free and overall survival or risk factors for recurrence and death. CONCLUSIONS Because venous and lymphatic embolizations were related to greatest risk of lymph node metastasis, we propose their evaluation in staging and therapeutic planning of patients with infiltrative tumors of the penis.

Abstract
BACKGROUND In 1988, Catalona proposed a modified bilateral inguinal lymphadenectomy for staging of lymph node metastasis from penile carcinoma. All three patients with penile carcinoma submitted to this procedure and without histologically confirmed metastases were free of disease within a mean follow-up time of 14.6 months. METHODS In a prospective study, the authors evaluated thirteen patients staged by the TNM system and submitted to modified bilateral inguinal lymphadenectomy. RESULTS None of the patients had histologic metastases in the medial quadrant lymph nodes. Two of these patients developed regional lymph node metastases within 13.2 months (mean follow-up time). CONCLUSIONS Catalona's procedure was not reliable. We therefore recommend standard inguinal lymphadenectomy as the minimal treatment for patients with infiltrating carcinoma of the penis.
