RESUMO

OBJECTIVE: The aim of this narrative review is to evaluate existing questionnaires on predictive models for endometriosis. These symptom-based models have the potential to serve as screening tools for adult women to detect endometriosis. DATA SOURCES: A comprehensive search of PubMed and Embase databases was conducted to identify studies on endometriosis screening. SELECTION OF STUDIES: The search targeted predictive models for endometriosis localisation, bowel involvement, need for bowel surgery and fertility. Due to the heterogeneity identified, a systematic review was not possible. A total of 23 studies were identified. DATA EXTRACTION AND SYNTHESIS: Among these studies, twelve included measures for general endometriosis, two targeted specific sites, four focused on deep infiltrating endometriosis (DIE), and three addressed the need for endometriosis-related bowel surgery. Many measures combined clinical, imaging and laboratory tests with patient questionnaires. Validation of these models as screening tools was lacking in all studies, as the focus was on diagnosis rather than screening. CONCLUSION: This review did not identify any fully validated, symptom-based questionnaires for endometriosis screening in adult women. Substantial validation work remains to establish the efficacy of such tools.

RESUMO

OBJECTIVES: To examine the relation of corticotropin-releasing hormone (CRH) family peptides with inflammatory processes and oncogenesis, emphasizing in vulvar inflammatory, premalignant and malignant lesions, as well as to investigate the possibility of lesion cells immunoescaping, utilizing FAS/FAS-L complex. METHODS: Immunohistochemical expression of CRH, urocortin (UCN), FasL and their receptors CRHR1, CRHR2 and Fas was studied in vulvar tissue sections obtained from patients with histologically confirmed diagnosis of lichen, vulvar intraepithelial neoplasia (VIN) and vulvar squamous cell carcinoma (VSCC). The patient cohort was selected from a tertiary teaching Hospital in Greece, between 2005 and 2015. For each of the disease categories, immunohistochemical staining was evaluated and the results were statistically compared. RESULTS: A progressive increase of the cytoplasmic immunohistochemical expression of CRH and UCN, from precancerous lesions to VSCC was observed. A similar increase was detected for Fas and FasL expression. Nuclear localization of UCN was demonstrated in both premalignant and VSCC lesions, with staining being significantly intensified in carcinomas, particularly in the less differentiated tumor areas or in the areas at invasive tumor front. CONCLUSIONS: Stress response system and CRH family peptides seem to have a role in inflammation maintenance and progression of vulvar premalignant lesions to malignancy. It seems that stress peptides may locally modulate the stroma through Fas/FasL upregulation, possibly contributing to vulvar cancer development.

RESUMO

The purpose of this systematic review is to identify common hysteroscopic findings suggestive of endometritis, chronic or subclinical, based on current scientific evidence. Data sources were MEDLINE, Embase, PubMed and other sources of grey literature. Four (4) authors independently selected studies addressing hysteroscopic detection of CE based on specific and clearly stated hysteroscopic criteria. The diagnosis was confirmed by histologic assessment, as stated in the materials and methods of these studies included. The initial search identified 599 studies, of which 21 met the inclusion criteria. Significant heterogeneity among published studies on Chronic endometritis (CE) remains the main limitation in performing a metanalysis and further analysis of diagnostic accuracy on the subject. Hysteroscopy is an important diagnostic tool in cases of chronic endometritis when accompanied by endometrial biopsies. Clinicians relate hyperaemia and endometrial oedema with chronic endometritis while more than half include micropolyposis as a pathognomonic feature of this subclinical condition. Micropolyps, stromal oedema, haemorrhagic spots, strawberry aspect, and hyperaemia are proposed as adequate indicators of hysteroscopic evidence of CE according to the literature. The impact of CE in long-term reproductive outcomes remain unclear, thus clinicians ought to communicate this to the patients and provide treatment where clinically appropriate. In addition, we present hysteroscopic images of histologically confirmed CE cases that could play the role of a hysteroscopic atlas.

RESUMO

INTRODUCTION: Adenomyosis is a common chronic disease in women of reproductive age, characterised by the presence of ectopic endometrial tissue within myometrium. Even though adenomyosis presents with chronic pelvic pain, menorrhagia or abnormal uterine bleeding, dysmenorrhoea, and dyspareunia and is often recognised after hysterectomies. However, the development of ultrasonography and magnetic resonance imaging has improved the pre-operative diagnosis of the disease. Hysteroscopy provides information in real time from the uterine cavity and the offers the possibility of obtaining direct biopsies. MATERIAL AND METHODS: The literature was searched via Pubmed and Embase with the following headings: diagnosis of adenomyosis or adenomyoma and office hysteroscopy, hysteroscopy findings of adenomyosis or adenomyoma, treatment of adenomyosis or adenomyoma with office hysteroscopy. RESULTS: The literature showed that hysteroscopy can identify superficial adenomyosis. There are a variety of hysteroscopic images that can be connected with the disease. New equipment like the spirotome has been used to access deeper layers of myometrium and obtain biopsies under direct vision from the adenomyotic areas. Different methods of treatment have been also described, like enucleation of focal superficial adenomyoma, coagulation, evacuation of cystic adenomyosis when the lesion is smaller than 1.5 cm, and resection of adenomyotic nodules in case of bigger lesions (>1.5 cm). Diffuse superficial adenomyosis is also managed by resection. CONCLUSIONS: Hysteroscopy has revolutionised the approach to adenomyosis. It is a useful tool in assessing mainly superficial adenomyosis. The role of hysteroscopy in surgical management of adenomyosis need to be confirmed with further studies.

RESUMO

Papillomatosis and recurrent duct ectasia could be treated with terminal lactiferous ducts excision. In this study we describe a modified miniinvasive procedure of terminal lactiferous ducts excision with a perinipple approach to the lower or upper half of the nipple. This technique avoids the much more extensive periareolar incision and has excellent aesthetic results.

RESUMO

Background: Ovarian teratomas are the most common type of ovarian mass during childhood and adolescence. There is no clear guidance for the management of the ovarian teratomas in children and adolescents. It is necessary, however, to understand the feature of these tumours and the indications for operating on them, and to put subjective criteria for the management in elective or emergency presentations. Methods: Medical records of patients between the age of 12 and 20 years old that underwent surgery for ovarian teratomas at the Department of Obstetrics and Gynaecology in University Hospital of Ioannina, between January 2000 and August 2022, were reviewed. A medical database was searched between January 2000 and August 2022 with the following keywords: ovarian teratoma, paediatrics and adolescents. Results: We present the results of forty patients, with a mean age of 11.8 years of age. All patients had surgery, where three out of four underwent oophorectomy and only one out of four underwent ovary-sparing operation; similar results were found in the literature. Conclusion: Ovary-sparing treatment is more common recently compared with the past, such as MIS compared with laparotomy. Better-organised and -planned prospective multi-centre studies are necessary to gain a deeper knowledge of the physiology and prognostic factors of teratomas in children.

RESUMO

Cell-cycle analysis has shown the presence of aneuploidy to be associated with poor prognosis. We developed an innovative rapid cell-cycle analysis protocol (the Ioannina protocol) that permitted the intraoperative identification of neoplastic cells in a plethora of malignancies. Herein, we aimed to investigate the potential role of cell-cycle analysis in the intraoperative characterization of gynecological malignancies. Women who underwent surgery for gynecological malignancies in our institution over a three-year period were included in this study. Permanent section pathology evaluation was used as the gold standard for malignancy evaluation. Total accordance was observed between flow cytometry and pathology evaluation. In total, 21 aneuploid cancers were detected following DNA index calculation. Of these, 20 were hyperploid and 1 was hypoploid. In addition, tumor samples were characterized by a significantly lower percentage of cells in G0/G1, as well as an induced tumor index. The response time for flow cytometry to obtain results was 5-6 min per sample. It seems that flow cytometry analyses for intraoperative tumor evaluation can be safely expanded to gynecological malignancies. This is a novel practical approach that has been proven valuable in several tumor types to date, and also seems to be reliable for gynecological malignancies. Intraoperative flow cytometry is expected to be crucial in decisions of lymph node dissection in endometrial cancers, due to its rapid response regarding the tumor invasion of part or all of the myometrial thickness. In this way, the surgeon can quickly modify the plane of dissection. Our results warrant the further investigation of applying iFC in larger, multicenter studies.

RESUMO

The aim of this study was primarily to evaluate the levels of progesterone, oestradiol and relaxin during different delivery modes and secondarily to assess specific traits and changes in maternal pelvic dimensions during pregnancy and childbirth, in correlation with foetal size and maternal hormonal profile. Nulliparous women (n = 448) were evaluated at three different stages, during first trimester, at the time of admission for childbirth and finally just before childbirth. Each examination included clinical internal pelvimetry, blood sample collection for defining the hormones levels in peripheral maternal circulation and ultrasonographic measurements of specific variables of the pubic symphysis and the foetus. We included 304 nulliparous women divided in three groups. According to our results, there was statistically significant difference at the mean progesterone, oestradiol and relaxin range during different modes of childbirth (p-value < .01). We also found significant correlation between the newborn's weight and the changes in pubic symphysis dimensions. However, no significant association was noted between maternal hormones studied and the changes in pelvic dimensions.IMPACT STATEMENTWhat is already known on this subject? Mode of childbirth can be affected by various aspects, like maternal pelvic anatomy, foetal size and hormonal status at the time of labour. Hormonal fluctuations along with mechanical forces caused by the foetus are believed to lead to morphological alterations to promote natural vaginal childbirth.What do the results of this study add? Our results clearly showed that successful vaginal delivery is characterised by the prevalence of a hyperoestrogenic environment with higher values of intrapartum oestradiol range and significant increase in maternal serum relaxin levels. We also proved that progesterone levels do not decrease during vaginal childbirth, and we concluded that foetal size seems to be the most crucial factor causing alterations in maternal pelvis during parturition.What are the implications of these findings for clinical practice and further research? Our findings could form part of a set of key factors included in future algorithms or computerised biomechanical models for predicting potential childbirth mode. Larger multicenter studies should confirm our results and evaluate their clinical significance in the decision making to ensure safe childbirth and optimal maternal and perinatal outcomes.

RESUMO

Inguinal endometriosis is a very rare entity with uncertain pathophysiology, that poses several diagnostic and therapeutic challenges. This study aimed to summarize published literature on the diagnosis and treatment of this condition. Thus, a systematic literature search was conducted in PubMed/MEDLINE, Scopus and the Cochrane Library. An effort was made to numerically analyze all parameters included in case reports and retrospective analyses, as well. The typical and atypical features of this condition, investigations used, type of treatment and histopathology were recorded. More specifications about the surgical treatment, such as operations previously performed, type of surgery and treatment after surgery have been acknowledged. Other sites of endometriosis, the presence of pelvic endometriosis and the follow-up and recurrence have been also documented. Overall, the search yielded 61 eligible studies including 133 cases of inguinal endometriosis. The typical clinical presentation includes a unilateral inguinal mass, with or without catamenial pain. Transabdominal or transvaginal ultrasound was typically used as the first line method of diagnosis. Groin incision and exploratory surgery was the treatment indicated by the majority of the authors, while excision of part of the round ligament was reported in about half of the cases. Chemotherapy and radiotherapy were initiated in cases of coexisting endometriosis-related neoplasia. Inguinal recurrence or malignant transformation was rarely reported. The treatment of inguinal endometriosis is surgical and a long-term follow-up is needed. More research is needed on the effectiveness of suppressive hormonal therapy, recurrence rate and its relationship with endometriosis-associated malignancies.

RESUMO

Endometrial cancer is the most common malignancy of the female genital tract. Approximately 25% of cases occur in premenopausal women, and up to 5% of cases occur in women who are younger than 40 years old. The survival rate in these cases is 99%; therefore, uterine-sparing management could be considered under strict criteria selection and the strong desire of the woman to preserve uterus and fertility. Diagnosis should be performed after a hysteroscopic biopsy instead of dilatation and curettage. The highest remission rate was achieved after combining a hysteroscopic resection with hormonal therapy compared to single hormonal treatment. The most common regiments are the following progestins: megestrol acetate (MA) and medroxyprogesterone acetate (MPA) taken orally with a daily dosage of 160 mg-320 mg for MA and 250 mg-600 mg for MP. Evaluations at three and six months could be performed by office endometrial biopsy and/or hysteroscopic directed biopsy especially in the presence of levonorgestrel intrauterine system, and in cases of remission, either a pregnancy attempt or maintenance therapy should be considered. After childbearing, hysterectomy with bilateral salpingo-oophorectomy is recommended, whereas ovarian preservation could be considered depending on the patient's age and whether they fulfil the strict criteria selection.

RESUMO

BACKGROUND: The aim of the study was to analyze the expression of nuclear receptor interacting protein 1 (NRIP1) and its partner ligand-dependent nuclear receptor co-repressor (LCOR) in endometrioid endometrial cancer and to investigate their association with estrogen receptor (ER), progesterone receptor (PR), Ki-67, clinicopathological parameters and patient survival. MATERIALS AND METHODS: Immunohistochemical evaluation was carried out to investigate the subcellular expression of NRIP1 and LCOR in endometrioid endometrial cancer samples. Statistical analysis was used to identify the correlations of NRIP1 and LCOR expression with clinicopathological variables and to estimate the survival rates. RESULTS: Endometrial cancer tissues exhibited higher expression of NRIP1 and LCOR in comparison with the normal tissues. Cytoplasmic LCOR expression was positively associated with ER and PR expression, while cytoplasmic NRIP1 expression was positively associated with ER expression. Moreover, cytoplasmic expression of NRIP1 was positively associated with Ki-67. CONCLUSION: Our study demonstrated that high cytoplasmic expression of LCOR may predict a longer overall survival of patients with endometrioid endometrial cancer. Patients with tumors expressing low levels of LCOR showed a worse survival compared to those expressing high levels.

RESUMO

PURPOSE: The aim of this study is to present a single department's experience on cervical cancer cases following previous excision of cervical intraepithelial neoplasia (CIN) and to discuss potential pathogenesis. METHODS: Nine cervical cancer cases meeting the inclusion criteria, with available pathological and follow-up data, were considered eligible for this study. RESULTS: The majority (7/9) have had clear excisional margins. The interval between initial treatment and cancer diagnosis ranged from 7 to 17 years. In all cases cancer diagnosis was "unexpected", as the prior cytological and/or colposcopic evaluation was not suggestive of significant cervical pathology. All cancers were squamous, and 5/9 at stage I. CONCLUSION: The long interval between initial CIN treatment and final diagnosis as well as the normal post-treatment follow-up may suggest a 'de novo' underlying but 'hidden' carcinogenesis process. It might be that dysplastic cells entrapped within crypts (or normal metaplastic affected by the same predisposing factors) continue undergoing their evolution, undetectable by cytology and colposcopy until they invade stroma and surfaces (endo- and/or ectocervical) approximately a decade later. Heavy cauterisation of cervical crater produced post excision might be a potential culprit of this entrapment.

RESUMO

PURPOSE: To evaluate the proposed criteria in a large sample and in additional subgroups in order to test the validity of the hysteroscopic features widely-accepted as suggestive of CE. METHOD(S): All patients (n: 2675) underwent outpatient hysteroscopy, with the vaginoscopic approach technique. Hysteroscopic features such as, stromal oedema, diffuse or focal hyperaemia, "strawberry aspect", micropolyposis and endometrial polyps, are often indicate the presence of chronic endometritis. All hysteroscopic features, alone and in combination were applied in 7 (seven) different subgroups of the sample: total sample, women in reproductive age, women with infertility issues/IVF screening, women with history of recurrent miscarriages, menopausal women, and women with hysteroscopic indication of Abnormal Uterine Bleeding (AUB) in women of reproductive age and postmenopausal bleeding (PMB). From each case, endometrial samples were obtained and immunohistochemistry, identifying CD-138, was applied in order to diagnose CE. RESULT(S): A total of 2675 patients were included of which, 1444 women were found with at least one of the proposed hysteroscopic features mentioned above. Stromal oedema, focal or diffuse hyperaemia and "strawberry aspect" in combination with micropolyposis demonstrated higher rates of diagnostic accuracy in the detection of CE correlated to histologic confirmation. Micropolyposis, stromal oedema, focal or diffuse hyperaemia and "strawberry aspect" offer great diagnostic accuracy in the hysteroscopic detection of Chronic Endometritis, regardless reproductive status and/or clinical presentation. Endometrial polyps are not valid hysteroscopic features in cases of suspected CE. CONCLUSION(S): Diagnostic hysteroscopy can accurately diagnose cases of CE, based on stromal oedema, focal or diffuse hyperaemia and "strawberry aspect", in combination with micropolyposis. In subgroups of infertile women, higher diagnostic accuracy based on the hysteroscopic features mentioned, was more likely to be achieved. Whether endometrial polyps are suggestive of CE, when identified during office hysteroscopy, remains controversial.

RESUMO

BACKGROUND: Chronic catheterization remains the only attractive option in specific circumstances, especially in neurologically impaired patients. Complications produced by the indwelling catheters, like patulous urethra and bladder neck destruction, usually lead to severe incontinence and significant nursing difficulties. Here, we describe a rare case, a urinary bladder opening representing massive and extensive destruction of the urethra and bladder sphincter due to an indwelling catheter. CASE PRESENTATION: We present a 46-year-old paraplegic woman complaining of recurrent febrile urinary tract infections and severe urinary incontinence. She suffered from persistent malodorous urine and skin breakdowns from constant urine leakage. The vaginal examination revealed extensive destruction of the urethra and a 10 cm opening permitting the urinary bladder wall to prolapse into the vagina. The patient underwent a combined surgical approach; a transvaginal bladder closure with anterior colporrhaphy and a Mitrofanoff procedure to ensure a continent stoma for future clean intermittent self-catheterization (CISC). The patient is compliant with CISC and, remains continent twelve years after surgery. CONCLUSION: This case demonstrates that in the era of CISC, there are still neurologically impaired females suffering from rare but critical adverse effects of indwelling catheters. The urethra and bladder neck erosion represent a demanding treatment assignment. The Mitrofanoff procedure for continent stoma and the transvaginal closure of urinary bladder opening produced a lifesaving potential treatment.

RESUMO

Platelets mediate circulating endothelial progenitor cell (EPC) recruitment and maturation, participating in vascular repair, however the underlying mechanism(s) remain unclear. We investigated the effect of platelet-rich plasma (PRP) on the functionality of CD34+-derived late-outgrowth endothelial cells (OECs) in culture. Confluent OECs were coincubated with PRP under platelet aggregation (with adenosine diphosphate; ADP) and nonaggregation conditions, in the presence/absence of the reversible P2Y12 platelet receptor antagonist ticagrelor. Outgrowth endothelial cell activation was evaluated by determining prostacyclin (PGI2) and monocyte chemoattractant protein-1 (MCP-1) release and intercellular adhesion molecule-1 (ICAM-1) membrane expression. Similar experiments were performed using human umbilical vein endothelial cells (HUVECs). Platelet-rich plasma increased ICAM-1 expression and PGI2 and MCP-1 secretion compared with autologous platelet-poor plasma, whereas ADP-aggregated platelets in PRP did not exhibit any effect. Platelet-rich plasma pretreated with ticagrelor prior to activation with ADP increased all markers to a similar extent as PRP. Similar results were obtained using HUVECs. In conclusion, PRP induces OEC activation, a phenomenon not observed when platelets are aggregated with ADP. Platelet inhibition with ticagrelor restores the PRP capability to activate OECs. Since EPC activation is important for endothelial regeneration and angiogenesis, we suggest that agents inhibiting platelet aggregation, such as ticagrelor, may promote platelet-EPC interaction and EPC function.

RESUMO

BACKGROUND: Transvaginal sonography (TVS) and office hysteroscopy are considered essential diagnostic tool for the gynecologic everyday practice. Through the years equipment developments in both techniques along with cumulative experience gained by the gynecologists result in a disunity among clinicians in choosing optimal diagnostic approach with regards to endometrial pathology. AIM: To evaluate the diagnostic accuracy of TVS versus office hysteroscopy (OHSC) in detecting endometrial pathology. Results were compared to available scientific evidence available among similar published studies. METHODS: Comparative Retrospective study performed at the Endoscopic Unit, Department of Gynecology, University Hospital of Ioannina, Greece. A total of 2675 cases were collected for this study from January 1997 until August 2019. All cases recruited underwent a TVS followed by office hysteroscopy (OHSC) for various indications according to the local protocol. Endometrial samples from all cases were obtained and histology confirmed the diagnosis. Sonographic and hysteroscopic results were correlated with histologic reports to assess the diagnostic accuracy of both techniques. RESULTS: In a total of 2675 cases recruited for this study, 23.2% were postmenopausal while the majority (76.7%) was of reproductive age. The commonest indication for hysteroscopy was abnormal uterine bleeding (AUB) accounting for 29.7% of the cases. Overall, TVS demonstrated diagnostic accuracy of 84.7%% in detecting endometrial pathology, compared to 97.3% of OHSC. Sensitivity, specificity, positive prognostic value (PPV) and negative prognostic value (NPV) of TVS detecting endometrial pathology were 84.0, 86.8, 95.3 and 63.0%, respectively. The corresponding values for hysteroscopy were 98.9, 95.1, 98.4 and 93.9%, respectively. Diagnostic value of both techniques was estimated in 6 (six) additional subgroups: total sample with AUB, women of reproductive age, women of reproductive age with AUB, women of reproductive age with infertility issues, postmenopausal women and postmenopausal women suffering from postmenopausal bleeding (PMB). All values were calculated with regards to histologic findings as gold standard technique. All results were correlated with scientific evidence collected from the international literature. CONCLUSION: Office hysteroscopy is a more reliable tool in detecting endometrial pathologies compared to TVS regardless of reproductive status or clinical presentation. TVS is likely to orientate and guide specialists on what to expect prior to an hysteroscopic intervention.

RESUMO

A healthy pregnancy requires the development of maternal-fetal immune tolerance against the semi-allogeneic fetus. The interactions between the trophoblastic cells and the maternal immune cells (p.e., natural killer cells, T cells, macrophages, dendritic cells and B-cells) are important for the development of the maternal-fetal immune tolerance and the placental growth and function. These interactions are mediated by cell to cell contact and secreted molecules such as cytokines, chemokines, angiogenic factors and growth factors. The maternal immune cells are present in normal non-pregnant and pregnant endometrium and there are several lines of evidence based on immunohistochemical and RNA sequencing data that the decidual immune cells and immune-related pathways display alterations in GTD, which may have pathogenetic and clinical significance. The present review focuses on the usefulness of the immunohistochemical analysis which provides multiparametric in situ information regarding the numbers, the immunophenotypes and the immunotopographical distributions of the decidual immune cells in tissue sections from normal pregnancy and GTD. We also discuss the significance of the immunohistochemical information in order to gain insight in the putative mechanisms explaining the alterations of the decidual immune cells in GTD and the potential implications of these alterations in the pathogenesis and the clinical behavior of GTD.

RESUMO

Background: Human papillomavirus (HPV)-DNA testing combined with self-sampling could increase cervical cancer screening effectiveness, utilizing a sensitive screening modality and an easy sampling method with minimal pain or discomfort. Self-sampling acceptability, though, is pivotal. Materials and Methods: This study is a nested cross-sectional survey within GRECOSELF, a cross-sectional study on HPV-based screening with self-sampling, aiming at investigating self-sampling acceptability among Greek women residing in rural areas, and the factors affecting it. Women between 25 and 60 years old were recruited by midwives participating in a nationwide midwifery network. Participants, after self-sampling, filled out a questionnaire with three sections, one regarding demographic characteristics, a second with questions pertaining to the participants' cervical cancer screening history, and a third with questions regarding the self-sampling process per se. Results: The sample included 13,111 women. Most participants (67.9%), including those screened or not in the past, would prefer self-sampling if assured that the results are not inferior to standard testing. Discomfort or pain during self-sampling was absent or minimal in 97.1% and 96.5% of the cases, respectively, and 74.4% of the women felt adequately confident that they followed the instructions correctly. Women mostly preferred self-sampling at home compared with health care facilities. Pain and discomfort during the procedure, although rare, were significant factors against acceptance. Most of the women reporting a negative impression had a negative experience with conventional sampling in the past. Conclusion: Self-sampling is highly acceptable. Acceptance can be further improved with proper communication of the process and its noninferiority compared with conventional screening.

RESUMO

Female genital Tuberculosis (TB) is a rare disease, that usually affects female patients of reproductive age living in developing countries. The diagnosis of the disease is quite difficult since there is no consensus on the appropriate screening and management needed. Female genital TB can mimic many other pathologies including advanced ovarian cancer. Laboratory findings or blood serum tests usually are not suggestive of the disease. Imaging findings can be misleading. The incidence of the disease in Greece is rare. We present a rare case report of a post-menopausal patient with female genital TB, mimicking malignancy and resulting to a lethal outcome. Laboratory and imaging findings were non-specific for the disease, leading to a false diagnosis of disseminated peritoneal carcinomatosis.

RESUMO

Oral squamous cell carcinoma (OSCC) is considered an aggressive malignancy, mainly due to its increased propensity to provide local and distant lymph node metastases. Gross chromosome instability (CI; polysomy/aneuploidy/monosomy), combined or not with specific gene alterations, is implicated in the development and progression of solid malignancies, including OSCC. In order to further study the relationship between these genetic alterations and the aggressive biological behavior of OSCCs, we investigated the frequency and impact of chromosome 9 numerical imbalances in these tumors. Fifty (n = 50) formalin-fixed, paraffin-embedded primary OSCC tissue sections were used. Chromogenic in situ hybridization (CISH) was implemented for detecting chromosome 9 (CEN-centromere enumeration) numerical alterations. Concerning the screening process in CISH slides, a novel, real-time reference and calibration grid platform was implemented. Chromosome 9 polysomy was observed in 8/50 (16%) tissue sections, whereas the rest of them demonstrated a normal, diploid pattern (42/50; 84%). Chromosome 9 polysomy was associated with the grade of differentiation of the examined tumors (p = 0.036). Chromosome 9 numerical imbalances (polysomy) were observed in sub-groups of OSCCs correlating with a progressive dedifferentiation of the malignant tissues. Concerning the implementation of the proposed grid-based platform as described above on CISH slides, it provides a novel, fast, and accurate screening mapping mechanism for detecting chromosome numerical imbalances.
