Small cell carcinoma of the ovary-hypercalcemic type (SCCOHT): A review of 47 cases.

OBJECTIVE: Small cell carcinoma of the ovary-hypercalcemic type (SCCOHT) is a rare disease with a poor prognosis. SCCOHT has recently been shown to be associated with SMARCA4 gene mutations as well as molecular and genetic similarities to malignant rhabdoid tumors (MRT). The objective of our study is to describe the clinical characteristics, treatment modalities and outcomes of 47 patients with SCCOHT. METHODS: We performed a retrospective analysis of 47 patients with SCCOHT evaluated at MD Anderson Cancer Center between 1990 and 2014. Medical records were reviewed for demographic information, pathologic findings, treatment regimens and outcomes. RESULTS: Median age at diagnosis was 30 years (range 5-46). All patients underwent surgery with unilateral salpingo-oophorectomy (USO) performed in 26 patients (55%), and hysterectomy with bilateral salpingooophorectomy (BSO) in 21 patients (45%). Sixteen patients (34.0%) had stage I disease, six (12.8%) stage II, 23 (48.9%) stage III, and two patients (4.3%) had stage IV disease. Information on adjuvant treatment was available for 43 patients: 83.3% received chemotherapy alone, 9.5% chemotherapy followed by radiotherapy, 2.4% chemoradiation, and 4.8% did not receive any adjuvant therapy. Median follow-up was 13.2 months (range, 0.1 to 210.7) with a median overall survival of 14.9 months. Multi-agent chemotherapy and radiotherapy were associated with a better prognosis. CONCLUSION: Our findings suggest that aggressive therapy including multi-agent chemotherapy and possibly radiotherapy may extend survival. Further study is needed to improve outcomes in these patients including the adoption of systemic therapies used in MRT as well as the development of novel agents targeting specific mutations.

Sentinel lymph node in endometrial cancer.

The aim of this study was to evaluate the possibility of identifying the sentinel lymph node and involvement of neoplastic cells in patients with endometrial carcinoma limited to the uterus, and also its correlation with the conditions of other pelvic and para-aortic lymph nodes. Forty patients with endometrial carcinoma, clinical staging I and II, were submitted to complete surgical staging through laparotomy, as recommended by FIGO in 1988. The sentinel node was investigated using patent blue dye in the myometrial subserosa. The sentinel node was excised and submitted to frozen section examination of specimen, stained with hematoxylin and eosin (H&E). Afterward, selective bilateral para-aortic and pelvic lymphadenectomy, total hysterectomy with bilateral salpingo-oophorectomy were performed. The lymph nodes excised were examined by means of paraffin-embedded slices stained with H&E and of imunohistochemistry with antikeratin antibody AE1/AE3. The sentinel lymph node was identified in 77.5% of patients (31/40), and 16.1% (5/31) presented neoplastic involvement in the node. In 25 cases of negative sentinel node, 96% (24/25) had no neoplastic involvement, and 4% (1/25) had other lymph node affected (false negative). In nine cases with no sentinel node identified, 55.5% (5/9) had lymph node involvement. The results of this study allow us to conclude that it is possible to identify the sentinel node using the methods described, and the pathologic examination significantly represents the same conditions of other pelvic and para-aortic lymph nodes.

Progesterone receptor (PROGINS) polymorphism and the risk of endometrial cancer development.

The progesterone receptor gene (PROGINS) has been identified as a risk modifier for benign and malignant gynecological diseases. The present case-control study is to evaluate the role of the PROGINS polymorphisms, as risk factor, for endometrial cancer development and to investigate the association between these genetics variants and clinical/pathologic variables of endometrial cancer. PROGINS polymorphism was examined in a total of 121 patients with endometrial cancer and 282 population-based control subjects, all located at the same area in São Paulo, SP, Brazil. The genotyping of PROGINS polymorphism was determined by polymerase chain reaction. The frequencies of PROGINS polymorphism T1/T1, T1/T2, and T2/T2 were 82.6%, 14.9%, and 2.5% in the endometrial cancer patients and 78.4%, 21.6%, and 0% in the controls, respectively. The chi(2) test showed a higher incidence of the T2/T2 genotype in the endometrial cancer group subjects, these results were statistically different (P= 0.012). However, due to the fact that there were no women in the control group showing homozygosis for the allele T2, the correct evaluation of odds ratio could not be properly calculated. Regarding the clinical and pathologic findings observed within the group of patients with endometrial cancer, there was significant correlation between T1/T2 genotype and the presence of myoma (P= 0.048). No correlations were observed among the other variables. These data suggest that the PROGINS polymorphism T2/T2 genotype might be associated with an increased risk of endometrial cancer.

Histologic studies of the effects of circulating hot saline on the uterus before hysterectomy.

STUDY OBJECTIVE: To evaluate a new device for endometrial ablation. DESIGN: (Canadian Task Force classification II-1). SETTING: University-affiliated hospital. PATIENTS: Thirty-two women scheduled for hysterectomy. INTERVENTIONS: Endometrial ablation and hysterectomy. MEASUREMENTS AND MAIN RESULTS: The new device for endometrial ablation was evaluated by studying depth of necrosis after staining for the oxidative enzyme NADH. Uniform endomyometrial necrosis was achieved at a depth of 2 to 4 mm with 90 degrees C saline circulated for 10 minutes. CONCLUSION: The procedure was successful in all patients, and there were no adverse clinical sequelae. (J Am Assoc Gynecol Laparosc 6(3):269-273, 1999)

Evaluation of Hydro ThermAblator for endometrial destruction in patients with menorrhagia.

OBJECTIVE: To describe endometrial destruction with the Hydro ThermAblator. DESIGN: (Canadian Task Force classification II-1). SETTING: University-affiliated hospital. PATIENTS: Twenty-six women with uncontrolled menorrhagia. INTERVENTION: Endometrial ablation with saline heated to 90 degrees C and circulated in the uterine cavity for 10 minutes under hysteroscopic control. MEASUREMENTS AND MAIN RESULTS: All patients tolerated the procedure well, all but one was satisfied with the results, and there were no significant side effects or complications. Seventy-seven percent of women were either amenorrheic or hypomenorrheic after 6 months, and 88% were amenorrheic or hypomenorrheic after 1 year, including one patient who was treated a second time; 87.5% were amenorrheic or hypomenorrheic at 18 months. One woman had persistent menorrhagia and was treated by hysterectomy. CONCLUSION: In this study, endometrial ablation was performed successfully with the Hydro ThermAblator in 25 of 26 women.

Importance of peniscopy, oncologic cytology and histopathology in the diagnosis of penile infection by human papillomavirus.

INTRODUCTION: Male genital infection by human papillomavirus is of particular importance since it is often asymptomatic. The patient generally presents no clinical lesion. Therefore, men represent an important reservoir of virus, playing a special role in the transmission and perpetuation of the disease. PATIENTS AND METHODS: In the present prospective clinical trial study, 190 sex partners of women with genital infection by human papillomavirus, associated or not with cervical intraepithelial neoplasia, were investigated. All patients were unaware of or denied the presence of a genital lesion. RESULTS: Cytologic examination revealed koilocytosis in 9 cases (4.7%) in the urethra and in 3 cases (1.6%) in the corona of the glans and the distal prepuce. Peniscopy with the previous use of 5% acetic acid revealed white lesions in 97.9% of the patients. Toluidine blue stained most of the lesions. At least one fragment revealed koilocytosis in the histopathologic study of 97 cases (51.05%). CONCLUSION: The three methods complement one another, allowing a more precise diagnosis of the infection in men.

Ultra-sonografia seriada do endométrio e da endocérvice durante o ciclo menstrual normal da mulher / Serial ultrasonography of the endometrium and endocervix during the normal menstrual cycle of women

Os relatos ultra-sonográficos do endométrio humano säo, em sua maior parte, obtidos de pacientes com esterilidade conjugal, nulíparas, fazendo uso de drogas indutoras da ovulaçäo. Essas pesquisas, geralmente, näo se acompanham do estudo histológico da cavidade uterina e preocupam-se, sobretudo, com o período ovulatório. Há, contudo, controvérsias na interpretaçäo das imagens. OBJETIVO. Estudas a ultra-sonografia do endométrio, no decorrer do ciclo menstrual normal. MÉTODOS. Os autores selecionaram 15 mulheres, eumenorréicas, multíparas, que näo faziam uso de drogas indutoras da ovulaçäo, DIU ou contra-conceptivos hormonais. todas foram examinadas no primeiro, no sétimo, no décimo-quarto eno vigésimo-primeiro dia do ciclo menstrual. Confrontaram-se os achados ecográficos com os resultados histológicos. RESULTADOS. Avaliaram a imagem ultra-sonográfica do endométrio em 66.66 por cento das mulheres no primeiro dia do ciclo. Em todas elas, no sétimo, décimo-quarto e vigésimo-primeiro dia essa imagem também pôde ser identificada e apreciada. Verificaram, durante o ciclo, aumento progressivo da espessura da imagem endometrial, de forma linear. O halo hipoecóico teveincidência progressiva, atingindo 93,33 por cento no vigésimo-primeiro dia do ciclo. CONCLUSÄO. As alteraçöes cíclicas do endométrio foram demonstradas pela ultra-sonografia. As modificaçöes endocervicais também foram detectadas. Todavia, säo menos exuberantes do que as observadas no endométrio

[Serial ultrasonography of the endometrium and endocervix during the normal menstrual cycle in women]. / Ultra-sonografia seriada do endométrio e da endocérvice durante o ciclo menstrual normal da mulher.

Articles on ultrasound of the human endometrium are in the majority of the cases based on studies of patients who have infertility and are taking drugs to induce ovulation. Such investigations do not include histological study of the endometrium and have focused on the ovulatory period. There is controversy in the interpretation of the images. PURPOSE--To evaluate the sonographic appearance of the endometrium during the normal menstrual cycle. METHODS--We studied 15 multiparous women with normal cycles, and who were not under drugs for ovulation induction, had neither IUD, nor were having oral hormonal contraceptives. They were seen on the first, seventh, fourteenth, and twentieth-first days of the menstrual cycle. The sonographic aspects were compared with the histological findings. RESULTS--We could see the images of the endometrium on the first day of the cycle in 66.66% of the patients. On the other visits we could study properly its features very well in all the patients. The endometrial image thickness increased in a linear pattern and the hypoechogenic halo was seen in 93.33% of the patients on the twentieth-first day of the menstrual cycle. CONCLUSION--The cyclic changes of the endometrium were shown with the sonography. The cyclic changes of the endocervix were evaluated too with the sonogram although they are not as remarkable as the endometrial ones.

[Comparison between pelvic endovaginal and transabdominal sonography in the measurement of the uterus and ovaries]. / Comparação entre a ecografia pélvica endovaginal e a transabdominal na mensuração do útero e dos ovários.

PURPOSE: this study compares endovaginal sonography to the transabdominal ultrasound in terms of their accuracy in the measurement of the uterus and ovaries. TYPE: prospective study. PLACE: São Paulo, SP, Brazil. PATIENTS: Forty-nine women were included in the study in order to assess the clinical suspicion of pelvic mass or because they had vaginal bleeding in initial gestation. The patients were submitted to transabdominal sonography and later to endovaginal ultrasound (5.0mHz transducer). Uterus and ovaries were measured. RESULTS: the volume of 27 left and 29 right ovaries was measured. Echographic hysterometry was performed in 49 women and statistically compared. The Wilcoxon rank sum test failed to show any significant difference between the two sonographic techniques in the measurement of uterus and ovary volume. CONCLUSIONS: endovaginal ultrasound presents several advantages over transabdominal scanning. Patient's discomfort is minimum because vesical repletion is not called for. Imaging resolution is magnified and morphologic details are clearly seen because the transducer is in close contact with pelvic viscera. Results do not evidence any significant difference in the uterine measurements with either method, and the statistical difference in ovarian volume was not significant either.

Patologia associada ao leiomioma uterino: revisäo de 600 casos / Pathology associated with uterine leiomyoma: review of 600 cases

Foram analisadas 600 pacientes com leiomioma uterino (LU), atendidas na Escola Paulista de Medicina, que se submeteram a terapêutica cirúrgica entre 1976 e 1987. O exame histopatológico das peças cirúrgicas confirmou a presença de neoplasia benigna e, na maioria das vezes, surpeendeu outras patologias associadas. Estudaram-se também, como grupo controle, 150 úteros (de histerectomias), procurando-se conhecer a freqüência dessas entidades patológicas associadas em näo portadoras de LU. As principais associaçöes encontradas foram: cervicite crônica, adenomiose, cistos foliculars, alteraçöes tubárias - congestäo, edema e processo inflamatório -, pólipos uterinos, hiperplasia endometrial, endometriose, neoplasias do ovário e do endométrio. A coexistência dessas condiçöes patológicas ocorreu em 71,17% dos casos. O leiomioma é a neoplasia mais freqüente do útero e da pelve (18,19). A coexistência do tumor com outras entidades patológicas é pouco citada na literatura, assim como suas possíveis inter-relaçöes. Por causa da alta freqüência do leiomioma na populaçäo, poder-se ia associa-lo, apenas de forma fortuita, a outras entidades nosológicas do trato genital. Interessados em saber se haveria patologias secundárias ao leiomioma ou coexistência meramente casual, e também se as associaçöes teriam o mesmo denominador comum, fizemos o presente estudo

[Pathology associated with uterine leiomyoma: review of 600 cases]. / Patologia associada ao leiomioma uterino: revisão de 600 casos.

The authors analyzed 600 patients with uterine leiomyoma examined at the Escola Paulista de Medicina and submitted to surgical treatment between 1976 and 1987. The uteri were carefully studied and leiomyomas were confirmed. Other diseases were also found in 71.17% of the cases. Uteri from hysterectomies performed for conditions other than leiomyoma were also studied for control purposes. Major conditions found were chronic cervicitis; adenomyosis; follicular cysts; tubal changes (congestion, edema, and salpingitis); uterine polyps; endometrial hyperplasia; endometriosis; ovarian and endometrial neoplasias.
