Abstract
The European Society of Gynaecological Oncology, the European Society for Medical Oncology (ESMO) and the European Society of Pathology held a consensus conference (CC) on ovarian cancer on 15-16 June 2022 in Valencia, Spain. The CC panel included 44 experts in the management of ovarian cancer and pathology, an ESMO scientific advisor and a methodologist. The aim was to discuss new or contentious topics and develop recommendations to improve and harmonise the management of patients with ovarian cancer. Eighteen questions were identified for discussion under four main topics: (i) pathology and molecular biology, (ii) early-stage disease and pelvic mass in pregnancy, (iii) advanced stage (including older/frail patients) and (iv) recurrent disease. The panel was divided into four working groups (WGs) to each address questions relating to one of the four topics outlined above, based on their expertise. Relevant scientific literature was reviewed in advance. Recommendations were developed by the WGs and then presented to the entire panel for further discussion and amendment before voting. This manuscript focuses on the recommendation statements that reached a consensus, their voting results and a summary of evidence supporting each recommendation.

Abstract
The agenesis of the upper lateral incisor is one of the most frequent aesthetic-functional problems in dentistry. The reported case concerns a 49 years old male patient with bilateral agenesis of teeth 1.2-2.2 and a root stump of tooth 5.2 temporarily rehabilitated through a Maryland bridge. Without orthodontic treatment, the only solution for implant-prosthetic rehabilitation of tooth 1.2 results therefore in the use of a 2.9 mm diameter implant. The clinical and radiographic control of the implant and the gingival stability at a distance of 1 year gives a positive result both clinically and radiographically. The use of the implant with a 2.9 mm diameter is therefore indicated in extreme cases of limited bone availability.

Abstract
Chronic dissection of proximal aortic neck is a rare occurrence in patients with abdominal aortic aneurysm (AAA) and a gold standard therapy has not been defined so far. Herein we report two successful cases of an original adjunctive procedure involving the transrenal placement of a self-expanding nitinol stent (E-XL aortic stent, Jotec GmbH, Germany) in order to fix a dissection flap in the aortic neck wall prior to the deployment of the bifurcated endograft. Primary technical success and midterm clinical success was achieved in both cases with freedom from any early or late reintervention. Scheduled follow-up angio-CT scans did not show any Type I endoleak, graft migration or renal/visceral arteries complications. According to these findings, patients with an AAA, presenting with a proximal neck with chronic dissection, can be safely and effectively treated by pre-emptive transrenal E-XL stenting and endovascular aneurysm repair.

Abstract
Diabetic mastopathy is an uncommon benign entity occurring in young women with type 1 diabetes. Its clinical and radiological signs are not specific and often mimic a breast carcinoma. However, the benign nature of this lesion is easily recognized on histological examination, visualizing dense keloid-like fibrosis, lymphocytic lobulitis and ductitis with lymphocytic perivascular inflammation, with or without epithelioid-like fibroblasts. Surgery can generally be avoided. The evolution of this entity is characterized by the risk of local growth, bilateralisation or recurrence after surgical treatment. We present a case in which the core biopsy allowed the diagnosis of a diabetic mastopathy and we discuss its clinical, diagnostic, pathological and therapeutic particularities.

Abstract
The cancerization of supernumerary breast is uncommon. So when this situation occurs, the diagnosis is often late. Cancers of ectopic breast tissue have been reported in the international literature, but to our knowledge, no cancer after excision of accessory breast gland has been published. This article describes a case of ectopic breast tissue cancer in axillary situation occurring several years after excision and details its specific diagnostic, therapeutic and prognosis.

Abstract
As a consequence of breast imaging development and increased interventional radiology, benign epithelial breast diseases (BEBD) represent a growing percentage of breast pathology diagnoses. BEBD include numerous entities such as cysts, fibrosis, adenosis, duct ectasia, which require neither surgery nor follow-up. Some BEBD have to be individualized (radial scars, papillomas, complex sclerosing adenosis, lobular intraepithelial neoplasia, flat epithelial atypia, atypical hyperplasia), being preinvasive lesions or markers of increased breast cancer risk, or being associated with suspect radiological aspect. BEBD should be managed in a pluridisciplinar way and correctly diagnosed by percutaneous biopsies or surgical specimens. The goals of surgery vary according to lesions. It always allows a complete surgical specimen analysis and therefore a search for atypical or cancerous cells. Surgery can also have a preventive role by reducing the risk of potential malignant transformation. Finally, it enables in some cases the excision of a radiologically suspect mass. So the aim of this review is to give a clinical and morphological description of most common BEBD, underlying their cancer risk, specific diagnosis, therapeutic, follow-up and psychological repercussions.

Abstract
The knowledge of the status of axillary lymph nodes (LN) of patients with breast cancer is a fundamental prerequisite in the therapeutic decision. In the present work, we evaluated the impact of fine-needle aspiration cytology (FNAC) of ultrasonographically (US) selected axillary LN in the diagnosis of LN metastases and subsequently in the treatment of patients with breast cancer. Axillary US was performed in 298 patients with diagnosed breast cancer (267 invasive carcinomas and 31 ductal carcinoma in situ DCIS), and in 95 patients it was followed by FNAC of US suspicious LN. Smears were examined by routine cytological staining. Cases of uncertain diagnosis were stained in immunocytochemistry (ICC) with a combination of anticytokeratin and anti-HMFG2 antibodies. Eighty-five FNAC were informative (49 LN were positive for metastases, 36 were negative). In 49 of 267 patients with invasive breast carcinoma (18%), a preoperative diagnosis of metastatic LN in the axilla could be confirmed. These patients could proceed directly to axillary dissection. In addition, US-guided FNAC presurgically scored 49 out of 88 (55%) metastatic LN. Of all others, with nonsuspicious LN on US (203 cases including 31 DCIS), in which no FNAC examination was performed, 28 invasive carcinomas (16%) turned out to be LN positive on histological examination. Based on these data, US examination should be performed in all patients with breast cancer adding ICC-supported FNAC only on US-suspect LN. This presurgical protocol is reliable for screening patients with LN metastases that should proceed directly to axillary dissection or adjuvant chemotherapy, thus avoiding sentinel lymph node biopsy.

Abstract
The increasingly popular use of somatostatin analogs in clinical practice for both diagnostic and therapeutic purposes prompted extensive investigations on somatostatin receptor (sst) expression in human tumors by autoradiography, nucleic acid analysis and, recently, immunohistochemistry (IHC). The currently employed radiotracer for scintigraphy (Octreoscan) is octreotide, a somatostatin analog having a high affinity for sst types 2, 3, and 5. In this study on 25 patients, we compared sst 2, 3, and 5 expression in surgical and biopsy specimens of lung tumors, as revealed by immunohistochemical and reverse transcriptase polymerase chain reaction (RT-PCR), with the octreoscan outcome (which was positive in 20/25 cases). By IHC, the tumors mainly expressed sst2 (17/25, 68%) at the cell membrane level, while sst 3 and 5 were detected in a fraction of cases (24% and 20%, respectively). Comparing RT-PCR and IHC data, a correlation was found in 83.3% of cases, while octreoscan findings and sst expression were correlated in 22/25 cases (88%). In addition, cytological and biopsy specimens expressed the same sst type found in the corresponding surgical sample, thus indicating that a cell membrane sst immunoreactivity in a biopsy reliably predicts the tumor-receptor profile before its resection. Finally, sst expression was not restricted to neuroendocrine lung tumors, but was also a feature of some non-neuroendocrine carcinomas, although to a lesser extent. The occasional expression of sst subtypes in intratumoral lymphocytes, endothelia and necrotic areas is an additional feature to be considered in the interpretation of Octreoscan findings, since the in vivo procedure does not allow to define the sst cellular distribution. IHC can therefore be usefully coupled to radionuclear investigations to better characterize the sst cellular location and subtype in lung tumors.

Abstract
A series of 1378 intra-operative frozen diagnoses performed in our department over two years (1998-1999) was studied in order to assess the agreement with the diagnosis on formalin-fixed, paraffin-embedded sections. In selected cases, a rapid immunostaining (IS) method was applied on frozen sections to solve diagnostic problems. Rapid IS allowed us to determine the histotype of poorly differentiated neoplasms, the origin of lung nodules and the presence of nests of neoplastic cells on resection margins. The method delayed the answer by about 20 minutes, and was always previously arranged with the surgeon. Rapid IS method was performed using routine reagents and was not repeated on formalin-fixed, paraffin-embedded sections of the same cases, thus avoiding additional costs.

Abstract
Two patients with a radically operated well differentiated neuroendocrine carcinoma (WDNC) of the lung who developed a carcinoid syndrome due to metastatic spread of the tumor are reported. Treatment with somatostatin analogue octreotide was administered to both patients following their refusal of a standard chemotherapic regimen. Prompt resolution of the carcinoid syndrome was observed in both following octreotide treatment and both patients are alive and well after more than four years without evidence of further progression of the tumor. It is suggested that octreotide should be considered as an effective therapy in WDNC for the control of the disease and associated paraneoplastic syndromes.

Abstract
Somatostatin receptors type 2 (sst2) have been frequently detected in neuroendocrine tumors and bind somatostatin analogues, such as octreotide, with high affinity. Receptor autoradiography, specific mRNA detection and, more recently, antisst2 polyclonal antibodies are currently employed to reveal sst2. The aim of the present study was to investigate by three different techniques the presence of sst2 in a series of 26 neuroendocrine tumors of the lung in which fresh frozen tissue and paraffin sections were available. It was possible, therefore, to compare, in individual cases, RNA analysis studied by reverse transcriptase polymerase chain reaction (RT-PCR), in situ hybridization (ISH), and immunohistochemistry. A series of 20 nonneuroendocrine lung carcinoma samples served as controls. RT-PCR was positive for sst2 in 22 of 26 samples, including 15 of 15 typical carcinoids, 5 of 6 atypical carcinoids, and 2 of 5 small-cell carcinomas. The sst2 mRNA signal obtained by RT-PCR was strong in the majority (87%) of typical carcinoids and of variable intensity in atypical carcinoids and small-cell carcinomas. A weakly positive signal was observed in 5 of 20 control samples. In immunohistochemistry, two different antibodies (anti-sst2) were employed, including a monoclonal antibody, generated in the Department of Pathology, University of Turin. In the majority of samples a good correlation between sst2 mRNA (as detected by RT-PCR) and sst2 protein expression (as detected by immunohistochemistry) was observed. However, one atypical carcinoid and one small-cell carcinoma had focal immunostaining but no RT-PCR signal. ISH performed in selected samples paralleled the results obtained with the other techniques. A low sst2 expression was associated with high grade neuroendocrine tumors and with aggressive behavior. It is concluded that 1) neuroendocrine tumors of the lung express sst2, and there is a correlation between the mRNA amount and the degree of differentiation; 2) immunohistochemistry and ISH are reliable tools to demonstrate sst2 in these tumors; and 3) sst2 identification in tissue sections may provide information on the diagnostic or therapeutic usefulness of somatostatin analogues in individual patients with neuroendocrine tumors.

Abstract
Data from literature show that whereas in non-GnRH-a controlled ovarian hyperstimulation cycles luteal phase supplementation is not crucial, its use in GnRH-a/gonadotropins protocols seems to lead to a definite reduction of the negative effects of such drugs. The most important side effect of the hCG use as luteal support is the increased rate of the ovarian hyperstimulation syndrome (OHSS). Therefore its use should be reserved for very selected patients, for those subjects with preovulatory levels of E2 < 2500 pg/ml. As regard the use of progesterone, most authors agree that it has less efficacy than hCG but this depends on the administration route.

Abstract
The endometrial effect of long-term vaginal oestriol (E3) therapy for urogenital atrophy was assessed in 23 post-menopausal women. Hysteroscopic and histological examinations were performed in each patient to assess endometrial atrophy before treatment and after 6 and 12 months of therapy (0.5 mg vaginal E3 for 21 days, then 0.5 mg twice weekly). The primary atrophic picture was confirmed at the end of the 6th month in all but one of the patients. In one case, the histology showed an abnormal stromal reaction with no epithelial alterations. Treatment was continued and after the 12th month complete atrophy was confirmed both hysteroscopically and histologically in all patients. Efficacy as regards vaginal and urogenital complaints was good. Our results demonstrate that in women with endometrial atrophy effective and well-tolerated treatment with vaginal E3 can be safely continued for up to 12 months.

Abstract
OBJECTIVE Evaluation of selective salpingography for diagnosis and treatment of tubal injection failure during hysterosalpingography (HSG). DESIGN Prospective study. SETTING Obstetrics and Gynecology Department, University of Genoa (Italy)--tertiary care. PATIENTS One hundred eighty infertile women with unilateral or bilateral proximal tubal injection failure during HSG were submitted to the procedure. INTERVENTION Under fluoroscopy, a 4.5-F nylon catheter (3-F tip) was inserted into the ostium with or without the aid of a J-shaped, coaxial, angiographic guide wire, and 2 to 3 mL of contrast medium were injected. The procedure lasts 20 to 30 sec/tube. MAIN OUTCOME MEASURES Of 155 tubal ostia, 145 (94.2%) were catheterized. RESULTS Of the 146 catheterized tubes, 110 (75%) were rendered patent. Of the others, 21 (14.3%) presented hydrosalpinx or distal obstructions, and isthmic obstruction was present in 5 (3.4%). Patency of at least one tube was achieved in 82 (81.2%) of the 101 catheterized women; 8 conceived spontaneously and 11 after gamete intrafallopian transfer to the recanalized tube. CONCLUSIONS During HSG, selective salpinography can be performed when proximal injection failure is observed to determine its cause or to restore patency.

Abstract
The aim of the study was to assess, in a small number of volunteers, the feasibility of transferring gametes by blind transcervical tubal catheterization. Forty patients underwent ovarian stimulation with a combination of a luteinizing hormone-releasing hormone analogue and exogenous gonadotrophin. Twenty-six patients were submitted to echographical oocyte retrieval and subsequent blind transcervical tubal transfer of the gametes. Successful cannulation of the tube was achieved in 18 subjects, at the first attempt and in four subjects at the second attempt; in the remaining four subjects, three or more attempts were needed. No complications were recorded during the tubal transfer. Seven clinical pregnancies (27% of all transfers) were obtained: three ended in abortion (11%), one was ectopic (4%) and three were ongoing (11%). These preliminary results encourage larger studies using this approach.

Abstract
Three different stimulation protocols were tested in patients affected by stage I and II endometriosis with no other causes of infertility, and scheduled for the gamete intrafallopian transfer technique. In two protocols a gonadotropin hormone-releasing hormone analog was used. The analog was started 6 months before stimulation in the former and along with the exogenous gonadotropin in the latter. Patients receiving only gonadotropin served as controls. Sixty patients were selected for this study; 55 reached laparoscopy. Whereas patients receiving either gonadotropin alone or simultaneous analog and gonadotropin had similar pregnancy rates, this was much higher in the patients undergoing a prolonged, medically induced hypoestrogenism. Prolonged analog pretreatment before ovarian stimulation may give better chances of success in endometriosis patients undergoing assisted reproduction techniques.

Abstract
The aim of the study was to compare the ability to prevent endogenous luteinizing hormone interferences, ovarian response, and success rate between two groups of patients undergoing GIFT procedures and treated with the same stimulatory protocol but with a different timing in the administration of the gonadotropin hormone-releasing hormone analogue (GnRH-a). The former underwent a concomitant administration of gonadotropin and analogue; the latter started stimulation only after the achievement of complete hypogonadotropinism. The analogue was always given intranasally and stimulation was identical in the two groups. Our results showed that (1) prevention of premature luteinization is obtained with both approaches and (2) no significant difference in terms of length of stimulation, gonadotropin doses, ovarian response, and success rate was recorded between the two groups.

Abstract
The purpose of this study was to compare early human chorionic gonadotropin secretion in two groups of pregnancies. These pregnancies were obtained, in one group, during a natural cycle, while, in the other group, they resulted from gamete intrafallopian transfers performed in hyperstimulated cycles. A logarithmic regression analysis was chosen to allow statistical comparison of serial plasmatic evaluation as hormone determinations were obtained, among patients, at different postovulatory days. The regression lines of the two groups of patients presented similar slopes. The unpaired t test performed on calculated data for 3 different days constantly revealed significantly higher levels (P less than 0.005) of natural vs stimulated cycles; thus a different origin on the x axis (days of the luteal phase) is deduced. These findings support the possibility of a delay in the appearance of human chorionic hormone in the patients undergoing gamete intrafallopian transfer technique.

Abstract
Three oral contraceptive preparations were studied in 60 healthy women. This randomized, comparative, baseline controlled study was designed to investigate the effects of the preparations on plasma lipids and lipoproteins. The following formulations were studied: a monophasic preparation containing ethinylestradiol and desogestrel (M-DSG) and two triphasic formulations containing ethinylestradiol and gestodene or levonorgestrel respectively (T-GSD and T-LNG). These preparations were studied for six treatment cycles. Total cholesterol and apoprotein B did not change in any group. Low density lipoprotein (LDL) cholesterol was significantly decreased in the groups of women treated with M-DSG and T-GSD respectively. No changes were observed in the T-LNG group. With M-DSG, significant increases were observed in high-density lipoprotein (HDL) cholesterol and HDL3 cholesterol, whilst HDL2 cholesterol did not change. With both T-GSD and T-LNG, no changes were observed in HDL cholesterol, whilst a significant increase in HDL3 cholesterol together with a trend to decrease in HDL2 cholesterol were observed. Apolipoprotein AI increased with the following ranking M-DSG greater than T-GSD greater than T-LNG. The LDL/HDL cholesterol ratio significantly decreased with both M-DSG and T-GSD. In the T-LNG group there was no change in this ratio. Triglycerides increased to the same extent in all treatment groups. As far as concerns the risk of arterial diseases, these three oral contraceptive formulations mostly induced negligible and/or partly favorable changes in plasma lipids and lipoproteins; however, the lipoprotein pattern during M-DSG treatment resulted better than during T-GSD, and the latter turned out to be better than during T-LNG.

Biology of nidation and ectopic implantation. ACTA EUROPAEA FERTILITATIS 1984; 15:347-55. [PMID: 6397029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 01/20/2023]
Abstract
The incidence of ectopic pregnancy has been steadily growing during the past decade; this fact can only partially be related to known factors (PID, use of IUDs, minipill, inductors of ovulation, sterilization reversal). Ectopic pregnancy is still a frequently misdiagnosed pathology; nevertheless, the recent advances in early diagnosis have allowed a decrease in the mortality rate and an improvement in subsequent fertility. In absence of obvious tubal abnormalities it is difficult to assess the cause of an ectopic implantation. Yet the factors regulating and nidation of the embryo in the human are far from clear. The transport of the embryo in the oviductal fluid depends on ciliary beat (generally regarded as the leading factor) and on muscle contractions mainly in the ampullary-isthmic and in the utero-tubal junction, where a sphincter action is stimulated by estrogens and relaxed by progesterone. Other substances (catecholamines, prostaglandins, oxytocin) are thought to be involved in ovum transport, although their role is unclear. Even less is known about local influence of the embryo on the oviduct. During preimplantation and implantation both the embryo and the mother engage in an elaborate interaction, elsewhere referred to as a 'conversation', involving long-and short-range signals. An essential role is played by the endocrine luminal milieu. A local action of estrogens on a progesterone-primed endometrium may be required for either the release of crucial signals for the blastocyst activation, or to make epithelial cells sensitive to the presence of the embryo, thus inducing the decidualization. In some animals, these estrogens are not ovarian, but synthesized by the blastocyst itself.(ABSTRACT TRUNCATED AT 250 WORDS)
