RESUMO

The rate of margins involvement and the associated recurrence risk in basal cell carcinomas (BCCs) varies widely in published works (7%-25% and 26%-67%, respectively). This study investigated the risk factors associated with incomplete excision and their relevance in surgical management when positive margins occur in 3957 BCCs excised in 2358 patients. This study performed a multivariate analysis on the database collected from all patients operated for BCCs in the Plastic Surgery Department between 1 January 1992 and 1 September 2007. All data collected (3957 excisions; 2358 individuals) were divided into complete and incomplete excisions groups and analyzed according to 14 variables. The overall rate of incomplete excisions was 14%. Mean age (68), size of the lesion (< 0.5 cm), BCC subtype (nodular with sclerosant aspects, sclerosant and basosquamous), location (face), infiltration depth (hypodermis and deep tissues), recurrent BCC and re-excised BCC were significantly associated with a higher rate of incomplete excision. The recurrence rate for incompletely excised tumours was 26.8%, while only 5.9% for completely excised tumours. Most of the risk factors associated to incomplete excision can be identified before surgery (by simple anamnesis and clinical examination) and successfully overcome by appropriate surgical margins. The high recurrence rate after incomplete excision and the low patient compliance towards follow-up should lead the surgeon to early re-excise residual cancer.

RESUMO

BACKGROUND: Neuroendocrine tumours are a heterogeneous group of separate clinico-pathological entities which have a common characteristic, i.e., expression of potential endocrine differentiation. In the ovary, the term "neuroendocrine" relates mainly to widely known carcinoids, but it may also be applied to rare neuroendocrine carcinomas as non-small cell type and small cell carcinomas of pulmonary type. In the literature only 11 cases of primary ovarian non-small cell neurendocrine carcinomas have been described and ten of these were associated with a surface epithelial ovarian tumour. Small cell neuroendocrine carcinoma of the ovary is a rare malignant tumour of the ovary. Advanced small cell carcinoma of the ovary is a very aggressive tumour with an overall poor prognosis and unfavourable outcome. CASE REPORT: The case reported is unique in the literature because the authors describe a rare case of endometrial metastasis of a primary ovarian non-small cell neurendocrine carcinoma without any surface epithelial ovarian tumour association. The tumour invaded up to less than half of the myometrium. The first symptoms were related to endometrial metastasis as metrorrhagia and pelvic pain while the asymptomatic presence of primary ovarian carcinoma was not acknowledged with physical examination, routine biochemistry, tumour markers, blood count and traditional transvaginal greyscale ultrasound. CONCLUSION: Magnetic resonance and three-dimensional (3D) ultrasonography with power Doppler are a great help in the diagnosis of ovarian localisation but only immunohistochemistry on histological material can provide a correct diagnosis. Immunohistochemistry expression of Ki67 is a useful marker of malignancy. Due to the rarity of this neoplasm, a general consensus for optimal treatment has yet to emerge. The reported biological aggressiveness of these tumours prompts combined treatment with radical surgery and adjuvant polychemotherapy.

RESUMO

BACKGROUND: Vulvar carcinoma is relatively rare gynaecologic malignancy. The most prevalent vulvar cancer is squamous cell carcinoma. It is not uncommon for patients to delay seeking medical attention or for physicians to delay diagnosing the condition. This delay results in many cases being diagnosed in advanced stage. The sentinel lymph node "concept" is attractive in vulvar cancer because it has the potential to avoid a radical vulvectomy associated with uni- or bilateral inguinofemoral lymphadenectomy and, thus, to avoid the morbidity associated with formal groin dissection. CASE REPORT: A case of an 88-year-old woman with advanced local vulvar cancer is presented. A study of the inguinal-femoral lymph nodes was also conducted with intraoperative vital blue dye peritumoral injection and as the sentinel node was found to be negative for malignant metastasis, a radical vulvectomy without bilateral inguinofemoral lymphadenectomy and without additional treatment (chemotherapy and/or radiotherapy) was performed. Follow-up was performed at one, three, six, nine, 12, 18 and 24 months. No local recurrence or distant metastasis was found. CONCLUSION: The sentinel lymph node procedure allows a less aggressive treatment to be carried out in patients with invasive vulvar cancer thus reducing the complications and morbidity of treatment. Moreover, reducing the operative stress can change the overall survival and reduce the mortality linked to complications and postoperative stress.

RESUMO

Purpose of this paper is to evaluate the risk of ateletasis in patients that underwent surgery of the abdomen (cesarean section), since the reflex of cough in these patients is notably altered for the limitation of the diaphragmatic excursions, due to analgesic contracture. The inhibition of cough's reflex causes retention of secretions with consequent bronchial obstruction and atelectasis. Personal experience in 6 cases of atelectasis following cesarean section is reported.

RESUMO

We have previously demonstrated that the expression of the soluble extracellular domain of the transmembrane ligand for Notch receptors, Jagged 1 (sJ1), in NIH 3T3 cells results in the formation of a matrix-dependent chord-like phenotype, the loss of contact inhibition of growth, and an inhibition of pro-alpha 1(I) collagen expression. In an effort to define the mechanism by which sJ1 induces this phenotype, we report that sJ1 transfectants display biochemical and cytoskeletal alterations consistent with the activation of Src. Indeed, cotransfection of sJ1 transfectants with a dominant-negative mutant of Src resulted in the loss of matrix-dependent chord formation and correlated with the restoration of type I collagen expression and contact inhibition of growth. We also report that the sJ1-mediated induction of Src activity and related phenotypes, including chord formation, may result from the inhibition of endogenous Jagged 1-mediated Notch signaling since it was not possible to detect an sJ1-dependent induction of CSL-dependent transcription in these cells. Interestingly, NIH 3T3 cells transfected with dominant-negative (but not constitutively active) mutants of either Notch 1 or Notch 2 displayed a similar Src-related phenotype as the sJ1 transfectants. These data suggest that the ability of sJ1 to mediate chord formation is Src-dependent and requires the repression of endogenous Jagged 1-mediated Notch signaling, which is tolerant to the destabilization of the actin cytoskeleton, a mediator of cell migration.

RESUMO

Severe hypothyroidism was discovered in a young woman in her 29th week of pregnancy. Previously, at the age of 12 years, she had undergone thyroid surgery for Graves' disease that resulted in persistent hypothyroidism and hypoparathyroidism. After surgical excision, the patient started levothyroxine replacement therapy and had regular control of thyroid function with normal findings throughout the years. The dose of levothyroxine had not been adjusted when the pregnancy started, and at the 29th week of gestation the patient had a thyrotropin (TSH) of 72.4 microU/mL. Ultrasound studies were performed in order to monitor fetal development. The fetal parameters analyzed before the adjustment of levothyroxine therapy showed growth retardation of various degrees. All analyzed fetal parameters (biparietal diameter, cranial and abdominal circumference, humerus and femur length) improved during the last 6 weeks of gestation, showing a good correlation with the newly achieved euthyroid state of the mother. The infant was clinically euthyroid at birth and was found normal at all evaluations of the neonatal hypothyroidism screening program (1, 5, 30 days).

RESUMO

Starting from an applied Bone Marrow Transplantation (BMT) study, the problem of "unexpected protectivity" in competing risks models is introduced, which occurs when one covariate shows a protective impact not expected from a medical perspective. Current explanations found in the statistical literature suggest that unexpected protectivity might be due to the lack of independence between the competing failures. Actually, in the presence of dependence, the Kaplan-Meier curves are not interpretable. Conversely, the cumulative incidence curves remain interpretable, and therefore seem to be a candidate for solving the problem. We discuss the particular nature of dependence in a competing risks framework and illustrate how this dependence may be created via a common frailty factor. A Monte Carlo experiment is set up which accounts also for the association between the observable covariates and the frailty factor. The aim of the experiment is to understand whether and how the bias showed by the estimates could be related to the omitted frailty variable. The results show that dependence alone does not cause false protectivity, and that the cumulative incidence curves suffer the same bias as the survival curves and therefore do not seem to be a solution to false protectivity. Conversely, false protectivity may occur according to the magnitude and the sign of the dependence between the frailty factor and the covariate. The paper ends with some suggestions for empirical research.

RESUMO

22 patients with endometrial cancer were studied. Twelve (54.5%) between 45 and 66 years were treated for six days before surgery with 160 mg per os of Megestrol acetate administered twice daily plus Beta interferon 3,000,000 IU- on alternate days for a week, plus Tamoxifen--two cp of 10 mg daily for six days. Before and after surgery and associated medical therapies the steroid receptor values (ER and PgR) were checked. After treatment an average increase was observed of the ER (19 fmol/mg) and PgR (17 fmol/mg). Of the twelve patients one died of a stroke during the study (8.33%); five (41.67%) showed complete remission (CR); four (33.34%) a partial remission (PR) and two (16.67%) were not responders (NR).

RESUMO

The Authors examine serum levels of HPRL in basal conditions and after TRH and sulpiride test in 15 patients with endometrial lesions (hyperplasia) and in 15 patients with endometrial adenocarcinoma included in a age range between 44 and 62 years, in which 7 patients present obesity, 10 patients present hypertension and 2 patients are hyperglycemic. The same examination is carried out in a control group of 30 healthy patients. Then the 15 patients with adenocarcinoma and 3 patients with adenomatosa hyperplasia are subjected to surgery and they estimate HPRL levels in endometrium. The results prove that there is no correlation between HPRL plasma levels and endometrium lesions and between endometrium HPRL. The Authors conclude that HPRL does not play a significant role in the pathogenesis of endometrial lesions; use of HPRL plasma levels as a marker of endometrial lesions is not possible.

RESUMO

The paper reports two cases of simultaneous endometrial carcinoma and endometrioid carcinoma of the ovary. The clinical and pathological characteristics are examined. Both patients underwent radical surgery with an intraoperative examination for metastatic involvement of the lumbo-aortic, iliac and infundibulo-ovarian lymphonodes. Surgery was followed by antiblastic (cisplatin, adriamycin, cyclophosphamide), hormonal (progestogens) and immuno-modulating (thymostimulin treatment). The two patients (respectively approximately 10 and 7 years after the operation) both enjoy good health.

RESUMO

A case of vulvar carcinoma arising from Bartholin's gland is described. At admission the patient showed a large suppurated swelling of the left labium maior. The neoformation reached the groin of the same side. Malignant cells were detected in biopsy specimens of both the vulvar swelling and the lymphonodes. The histological test showed a vulvar carcinoma arising from Bartholin's gland. The vulvar swelling and the ulcerated lesion were removed and the patient was treated with radiotherapy, chemotherapy (bleomicina) and immunomodulant therapy (Timostimoline). Pulmonary methastases were detected eighteen months after the operation and the patient died two years later.

RESUMO

The authors exopound three cases of women affected by endometrial carcinoma in which the ascithis has represented the first clinic manifestation in absence of metrorrhage (first two cases); in the third case, instead, the ascithis has appeared four years after the surgical operation of total laparohysterectomy with bilateral annexiectomy and telecobaltotherapy. The association of the malign ascithis with endometrial adenocarcinoma is of rare observation. The Authors think very likely that the intraperitoneal semination in the cases they examined, is due to the infiltration of the myometry, of the regional and iuxtaregional lymphonoids with formation of ascithis.

RESUMO

The RIA method has been used to assay the squamous cell carcinoma antigen in the serum of twenty-four patients suffering from cervical cancer. The results obtained showed expressive differences between the levels in women with metastatic relapse and in those in remission, but the SCC antigen is particularly useful in the therapeutic monitoring, since it can assess of the current treatment.

RESUMO

The Authors have carried out determinations of AFP in the serum and of CEA in serum and in surgically removed tissue of 67 patients with genital tract's malignant tumors. As the results obtained among values of pre and post operatory CEA and tissue concentrations are incongruous, they believe useful, within the monitoring of patients with gynecological cancer, dosing CEA in the serum and also on the surgical section trying to reduce so the minimum positive false and negative false. Finally the repeated dosage of these antigens allows to follow the local replaced or the metastasis after some month, before the symptoms are clear.
