Computerized nuclear morphometry for the prediction of inguinal lymph nodes metastases in squamous cell carcinoma of the vulva

This study evaluated the sensitivity and specificity of computerized morphometry in predicting lymph nodes metastases (LNM) in patients with squamous cell carcinoma (SCC) of the vulva. Histologic samples obtained from 20 consecutive cases of SCC of the vulva with positive inguinal LNM were morphometrically assessed and compared with samples from 20 consecutive cases of vulvar SCC negative for LNM. Computerized morphometry was performed on tumor cells and on adjacent nonneoplastic epithelial cells located 2-4 mm from the tumor margins. Computerized morphometric variables of tumor cell nuclei in patients with negative LNM significantly differed from those in patients with positive LNM. Morphometric differences in nuclear size and contour regularity were detected when comparing the nonneoplastic nuclei adjacent to the tumor of both groups. Multivariate analysis showed that the only independent predictors of LNM were the depth of the invasion (P= 0.005) and the mean nuclear roundness of the nonneoplastic nuclei adjacent to the tumors (P= 0.008). Using these variables, a discriminant score revealed a sensitivity of 90% and a specificity of 86.4% for predicting LNM in SCC of the vulva. Our data suggest that cells from the primary tumors with LNM differ morphometrically from primary tumors with no LNM. In addition, normal epithelial cells adjacent to the tumor express morphometric changes between the two groups. The results of our study justify the need for a prospective study of a larger number of patients to evaluate the reproducibility and the clinical use of the data.

The clinical benefit of cisplatin-doxorubicin combination in heavily pretreated ovarian cancer patients

15052

Background: Cispatin-doxorubicin (Adriamycin) combination (50 mg/m2 each every 3 weeks) was used to treat ovarian cancer patients after failure of various chemotherapy lines. Methods: Eighteen patients were treated. Their mean age was 59 years (median 57.8, 41.3–70.3). They all had post operative first line carboplatin combination therapy (77% taxol containing) and all achieved NED status at end of therapy. They relapsed within 1–74 months from end of carboplatin therapy (median 9.5, mean 14.1). 3/13 patients (23%) were platinum resistant relapsing within less than six months. Second line therapy included carboplatin retreatment in 8/18 patients (44.5%) - (combined with taxol in 5 and as single agent in 3 patients). All patients received Topotecan therapy, 8 as second line, 6 as third line and 4 as forth line of therapy. Cis platin - Adriamycin combination was used as 3rd to 6th line of therapy (median 4th). All patients were in good general condition with normal renal function and had clinical evidence of recurrent disease confirmed by clinical examination and/or CT scan and CA125 level. 6/18 patients (33.3%) had severe symptoms of disease, 6/18 (33.3%) mild to moderate symptoms and 6/18 (33.3%) were asymptomatic. Results: 3–11 cycles of therapy were administered (median 7) using 60–100% of planned dose (median 100). Treatment was generally well tolerated with Grade III toxicity in 4/18 patients (22.2%) - (myelotoxicity in 2 and asthenia in 2 patients). 4/18 patients (22.2%) reported quality of life improvement, 4/18 (22.2%) reported quality of life deterioration and 10/18 (65.6%) stable quality of life during therapy. 13/18 patients (72.2%) benefited from therapy. 5/18 (27.7%) achieved complete response, 3/18 (16.8%) partial response and 5/18 (27.7%) minimal response or disease stabilization. All three platinum resistant patients responded: two achieved complete response and one minimal response. Mean time to progression in all responding patients was 9.4 months (median 8.6, 2.6–16.5). Conclusions: We concluded that Cis-Platin - Adriamycin combination is still effective in heavily pretreated ovarian cancer patients and clinical benefit can be achieved with reasonable toxicity. The combination can be considered an additional treatment option.

A multicenter study of CA 125 level as a predictor of non-optimal primary cytoreduction of advanced epithelial ovarian cancer

AIMS

To provide a large database of pre-operative CA 125 levels which may predict inappropriate cytoreductive surgery in patients with advanced epithelial ovarian cancer.

METHODS

A multicenter review of the records of 424 patients with FIGO stage III and IV epithelial ovarian cancer of patients who underwent primary cytoreductive surgery was performed. The validity of pre-operative CA 125 level measurement as a single predictor of the possibility to achieve only suboptimal cytoreduction was evaluated by calculating the sensitivity and the specificity of various cut-off values. The relative importance of different cut-off values in achieving the best predictive validity was assessed by a receiver operating characteristics (ROC) curve.

RESULTS

Optimal cytoreduction (largest diameter of residual tumour < or =1 cm) was achieved in 242 patients. The median CA 125 level in optimally cytoreduced patients was lower than in those patients suboptimally debulked (304 vs 863 U/mL; p<0.001). The area under the ROC curve was 0.65 (95% confidence interval, 0.60-0.71) and the CA 125 threshold derived from the ROC was 400 U/mL. The accuracy of the test at this level was 62%.

CONCLUSIONS

The clinical applicability of the ROC derived CA 125 threshold is limited. The data accrued in the study provides a basis for decision-making regarding the place of primary surgery various CA 125 levels.

Decreased level of the cell cycle regulator p27 and increased level of its ubiquitin ligase Skp2 in endometrial carcinoma but not in normal secretory or in hyperstimulated endometrium

p27 is a cyclin-dependent kinase (CDK) inhibitor whose specific late G(1) destruction allows progression of the cell across the G(1)/S boundary. The protein is ubiquitinated by S-phase kinase-interacting protein-2 (Skp2) following its specific phosphorylation, and is subsequently degraded by the 26s proteasome. There is a direct relationship between low level of p27 and rapid proliferation occurring in several benign states and in many malignancies. In the glandular cells of the normal endometrium, the level of p27 is exceedingly low during the proliferative phase, whereas it is markedly increased during the secretory phase. The expression of p27 in endometrial carcinoma is very low but has been found to increase following treatment with progesterone. However, estrogen exposure is considered as a major risk factor in developing endometrial cancer. The implications of the high dose of estrogen and progesterone induced during IVF treatment are still unknown. We have examined the expression of p27 and Skp2 as well as of Ki67 proliferation marker by using endometrial extracts and cells from normal endometrium, from ovarian hyperstimulated patients, and from endometrial carcinoma patients. The expression of p27, Skp2 and Ki67 was found to be similar in both normal secretory endometrium and endometrium from ovarian hyperstimulated patients. In striking contrast, p27 is significantly lower while Skp2 and Ki67 are significantly higher in the endometrial carcinoma and in endometrium from the proliferative phase compared with their normal secretory counterpart tissue.

Vaginal evisceration long after vaginal hysterectomy

BACKGROUND

Vaginal evisceration can take place many years after vaginal surgery.

CASE

An 87-year-old woman presented with evisceration of small bowel through the vagina, 15 years after she underwent a vaginal hysterectomy. On physical examination, her vital signs were normal. Forty centimeters of small bowel was visible emerging from the vagina, appearing viable and nonedematous. Because of the high surgical risk, the bowel was replaced and the defect in the vaginal wall was repaired transvaginally.

CONCLUSION

Vaginal evisceration can be treated by a transvaginal surgical approach. Factors such as the medical condition of the patient and the viability of the herniated viscus should dictate the optimal approach in each case.

Pregnancy outcome after laparoscopy or laparotomy in pregnancy

STUDY OBJECTIVE

To assess obstetric performance and fetal outcomes after laparoscopy or laparotomy performed during pregnancy.

DESIGN

Nationwide, multicenter, retrospective chart review (Canadian Task Force classification II-2).

SETTING

Seventeen hospitals throughout Israel: 12 university or university-affiliated hospitals and 5 general hospitals.

PATIENTS

Three hundred eighty-nine pregnant women.

INTERVENTION

Laparoscopy or laparotomy for various indications.

MEASUREMENTS AND MAIN RESULTS

Of 192 laparoscopies performed, 141 were during the first, 46 during the second, and 5 during the third trimester; respective figures for 197 laparotomies were 63, 110, and 24. No intraoperative complications were reported for either procedure. Six and 25 women had complications after laparoscopy and laparotomy, respectively. There was no significant difference in abortion rates between groups. Mean gestational age at delivery and mean birthweight were comparable between groups. No significant difference was found in frequency of fetal anomalies between groups or when compared with the Israel register of anomalies.

CONCLUSION

Operative laparoscopy seems to be as safe as laparotomy in pregnancy.

Endometrial ablation for the postmenopausal woman

The postmenopausal woman with abnormal uterine bleeding is considered at risk for developing endometrial neoplasia or one of its precursors. She requires prompt evaluation of the endometrium followed by adequate treatment. In the subgroup of postmenopausal women taking hormone replacement therapy (HRT), the risk of abnormal bleeding is by far higher, is the main reason for discontinuing HRT, and deserves additional attention.

BRCA1 germline mutations in women with uterine serous papillary carcinoma

OBJECTIVE

To determine the possible effects and incidence of BRCA1 and BRCA2 germline mutations in uterine serous papillary carcinoma.

METHODS

We screened DNA from 12 women with uterine serous papillary carcinoma for BRCA1 and BRCA2 germline mutations common in the Jewish population (BRCA1-185delAG and 5382insC, BRCA2-6174delT). In women with germline mutations, tumor DNA was screened for loss of heterozygosity at the appropriate loci.

RESULTS

Nine women were of Jewish Ashkenazi origin and three were non-Ashkenazi. Two of nine Ashkenazi women were carriers of germline mutations: one 185delAG mutation and one 5382insC mutation. Five women had histories of breast carcinoma before diagnosis of uterine serous papillary carcinoma. Family histories of seven women had at least one first-degree relative with malignant disease. Of those, four had at least one first-degree relative with breast, ovarian, or colon carcinoma. Both carriers had strong family histories of breast-ovarian carcinoma. Loss of heterozygosity analysis found loss of the wild-type BRCA1 allele in the primary uterine tumors.

CONCLUSION

BRCA1 germline mutations were observed in two of nine of the women in this series. The loss of heterozygosity in the tumor tissue of the carriers, coupled with the high frequency of family and patient histories of breast or ovarian malignancies, suggest that uterine serous papillary carcinoma might be a manifestation of familial breast-ovarian cancer.

A clinical review of borderline glandular cells on cervical cytology

OBJECTIVE

To review the diagnoses and diagnostic pathway of women presenting with borderline glandular cells on cervical cytology. To outline the basis of clinical approach of these women.

DESIGN

Retrospective review.

POPULATION

Forty-three women referred to the hospital department over a 32-month period.

METHODS

Review of the casenotes for the demographic data, previous cervical cytology and/or histology report, indication for the smear resulting in borderline glandular cells, colposcopic findings, diagnostic and/or treatment procedures, final diagnosis and current status.

RESULTS

The average age was 36.7 years. Twenty-four women (56%) had clinically significant lesions: seven women (16%) presented with cancers, of which one was endometrial in origin, and 17 (40%) with intraepithelial neoplasia (CIN and cervical glandular intraepithelial neoplasia (CGIN)). Sixty-seven percent of all clinically significant lesions were of squamous origin. Thirty-seven had histological diagnosis, while six went on to cytological surveillance. Colposcopy was the most significant predictor for clinically significant lesions (P < 0.05). Punch biopsies and loop excisions were diagnostic when based on abnormal colposcopic findings. Brush cytology was appropriate follow up for asymptomatic, premenopausal women with no colposcopic abnormality. In addition, endometrial sampling was recommended in the peri- and postmenopausal women.

CONCLUSION

Borderline glandular cells have a high incidence of clinically significant lesions. Immediate referral for colposcopy and assessment is strongly recommended in women with two borderline glandular smears to avoid delays in potential cancer diagnosis.

Bell palsy complicating pregnancy: a review

The aim of the present work was to review the published evidence on the association of Bell palsy (BP), an acute idiopathic peripheral facial paralysis of unknown etiology, with pregnancy. Reports have shown that women of reproductive age are affected two to four times more often than men of the same age, and pregnant women 3.3 times more often than nonpregnant women. The apparent predisposition of pregnant women to Bell palsy has been attributed to the high extracellular fluid content, viral inflammation, and immunosuppression characteristic of pregnancy, but findings are controversial. Most cases of Bell palsy occur in the third trimester or the puerperium. Onset is acute and painful. Some authors suggest that Bell palsy increases the risk of hypertension and toxemia of pregnancy, whereas the pregnant state, in turn, may affect the course and severity of disease. Recovery is usually good; poor prognostic markers are recurrence in subsequent pregnancy and bilateral disease, both of which are rare. Neonatal outcome is apparently unaffected, although this has been studied rarely. The preferred mode of management remains undecided; it is usually confined to supportive care. Corticosteroids in pregnancy are controversial. We think clinicians should be aware of these findings to avoid unnecessary testing and treatment and to help the patient cope with this acute, painful disease.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians

LEARNING OBJECTIVES

After completion of this article, the reader will be able to identify the potential etiologies of Bell palsy associated with pregnancy and to describe the clinical presentation of this condition in pregnancy and its likelihood for recovery.

[Vaginal vault prolapse: repair by sacrospinous ligament fixation]

Sacrospinous ligament fixation is a well-known method for correction of vaginal vault prolapse. The procedure is primarily indicated after hysterectomy and as a prophylactic measure for total uterine prolapse. 8 women with post-hysterectomy vaginal vault prolapse aged 48-72 years, were referred 1-25 years following primary surgery. Sacrospinous ligament fixation was elected to enable simultaneous correction of cystocele and rectocele, and to preserve sexual function. All operations were completed without significant complications. In 6 of the 8 patients located for long-term interview, 1 reported mild bulging of the introitus, another mild urinary stress incontinence, urgency and frequency and 1 reported frequency only. Sexual function in 4 was without complaints. Defecation in all patients was normal. We conclude that this operation is safe and effective. We encourage gynecologic surgeons to consult an experienced tutor prior to performing this procedure, as this type of surgery is quite dangerous and many gynecologists are not familiar enough with it.

The role of laparoscopic surgery in the management of endometrial cancer

OBJECTIVE

To assess the place of laparoscopically assisted vaginal hysterectomy in the treatment of endometrial cancer.

DESIGN

A retrospective uncontrolled case series.

SETTING

Gynaecological Oncology Department, Queen Elizabeth Hospital, Gateshead.

POPULATION

Women with endometrial cancer referred to this centre from August 1992 to August 1997.

MAIN OUTCOME MEASURES

Success of laparoscopically assisted vaginal hysterectomy, operative morbidity, and the length of hospital stay.

RESULTS

Laparoscopically assisted vaginal hysterectomy was successful in 35 of 40 women (88%). Five women required laparotomy. Two women sustained injury to the inferior epigastric vessels. One sustained injury to the small intestine requiring later laparotomy and three women required a blood transfusion. The mean hospital stay was 3 x 3 days (SD 1 x 5). Three women died of the disease within one year of their operation.

CONCLUSION

Laparoscopically assisted vaginal hysterectomy is a feasible treatment for endometrial cancer. It can be performed successfully in high risk population who are medically unfit and overweight. However, a larger randomised study is required to assess the morbidity compared with the traditional open approach.

Is uterine serous papillary carcinoma a BRCA1-related disease? Case report and review of the literature

OBJECTIVES

Type II endometrial carcinomas are estrogen-independent and have adverse histologic features and a substantially poorer prognosis. No risk factors have been identified. Interestingly, there is a striking clinical and histopathological similarity between serous papillary carcinomas of the ovary (OSPC), endometrium, and peritoneal cavity, suggesting a common oncogenic mechanism. Several common molecular alterations were found using molecular comparative analysis of OSPC and uterine serous papillary carcinoma (USPC). Germline mutations in the BRCA1 tumor suppressor gene predispose to breast and ovarian cancer but no association with sporadic endometrial cancer has been found. A family of Ashkenazi Jewish origin, in which one sister was first diagnosed with USPC and the second diagnosed with OSPC, led to the hypothesis that a BRCA mutation may contribute to USPC.

METHODS

Genomic DNA from both patients as well as two unaffected siblings was analyzed for the three mutations common in Ashkenazi Jews. Loss of heterozygosity (LOH) analysis was performed on DNA extracted from USPC tumor tissue.

RESULTS

Both affected sisters tested positive for BRCA1 5382insC germline mutation. LOH analysis confirmed the results.

CONCLUSIONS

We present a breast-ovarian cancer family including two sisters with advanced serous papillary carcinomas of endometrial and ovarian origins, carrying the same BRCA1 mutation (5382insC). LOH analysis on USPC tumor DNA showed loss of the wild-type allele, suggesting a causal relationship between the germline BRCA1 mutation and USPC. We believe a study examining BRCA1 mutations in a large cohort of women with this high-risk endometrial carcinoma is warranted. A positive finding may have implications for surveillance and prophylactic surgery in carriers of BRCA1 mutations.

Laparoscopic port-site metastasis of an early stage adenocarcinoma of the cervix with negative lymph nodes

BACKGROUND

Port-site metastasis (PSM) following laparoscopic surgery for cancer is being increasingly recognized as a potential problem; the majority of cases appear following laparoscopy for a pelvic mass that subsequently proved to be malignant or in the case of a disseminated intraperitoneal disease. The rare cases of PSM following laparoscopy for endometrial and cervical cancer have all been associated with the presence of regional lymph node metastasis or disseminated disease in the peritoneal cavity. We present here a case report of PSM in the absence of spread beyond the primary tumor.

CASE

A 48-year-old woman with stage IA1 adenocarcinoma of the cervix was treated with laparoscopically assisted vaginal hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic node dissection. The pathologic study revealed an endocervical adenocarcinoma confined to the cervix with negative lymph nodes. Nine months postoperatively, a cutaneous metastasis at the port-site was diagnosed. This was treated with wide local excision of the recurrence and the port-site track. Explorative laparotomy and para-aortic node sampling showed no evidence of recurrence elsewhere.

CONCLUSION

This case emphasizes the risk for PSM in laparoscopic surgery performed for early stage disease.

Transvaginal evisceration of small bowel after radical hysterectomy and pelvic lymphadenectomy

Vaginal evisceration is a rare event. This case report describes a 45-year-old woman who presented 8 days following radical hysterectomy and lymph node dissection for stage 1B squamous cell carcinoma of the cervix with small bowel evisceration through the vagina. She was treated by laparotomy and resection anastamosis of a discolored part of the distal ileum.

Thrombocytosis in women with vulvar carcinoma

Thrombocytosis (platelet count >400 x 10(9)/L) is frequently found in association with malignant disease. Although the pathogenesis of thrombocytosis in malignancy is currently unclear, it appears to be a poor prognostic factor in patients with lung, colon, breast, and cervical carcinoma. The current study was initiated to assess the incidence of thrombocytosis in vulvar carcinoma and to evaluate its prognostic significance for patients with vulvar carcinoma. The pretreatment platelet counts of 201 women treated for vulvar cancer were reviewed and correlated to the patient's age, stage of disease, node status, histologic type, and outcome. Differences between categories were analyzed by means of the ANOVA test, and survival was compared using the log-rank test on the Kaplan-Meier life table. Thrombocytosis was presented in 14.92% of patients with vulvar malignancies and in 15.46% of patients with squamous cell carcinoma of the vulva. No correlation was found between thrombocytosis and tumor size, incidence of lymph node metastases, or stage of the disease. The 5-year survival rate for patients with thrombocytosis was 89.29%, which was not significantly different from the 76.47% 5-year survival of patients with normal platelet counts (P = 0.586). When adjusted for age, histological differentiation, number of tumors, staging, incidence of nodal metastases, platelet count, hemoglobin, and white blood count, only the staging, number of tumors, and histological differentiation were associated with an unfavorable prognosis (P = 0.0001, P = 0.003, P = 0.03, respectively). Thrombocytosis was not found to be a prognostic factor in patients with carcinoma of the vulva in this series of 201 patients.

Does pregnancy affect medical ethical decision making?

OBJECTIVE

We studied and compared the attitudes of pregnant women v new mothers in an attempt to confirm changing patterns of maternal response towards medical ethical decision making in critically ill or malformed neonates.

DESIGN

Data were obtained by questionnaires divided into three sections: 1. sociodemographic; 2. Theoretical principles which might be utilised in the decision-making process; 3. Hypothetical case scenarios, each followed by possible treatment options.

RESULTS

Pregnant women (n = 545) consistently requested less aggressive medical intervention for the hypothetical cases than did new mothers (n = 250) [Trisomy 18: 57% v 42%; p = 0.0004; Asphyxia: 75% v 63%; p = 0.0017; Down's syndrome 81% v 62%; p = 0.0001; LBW 85% v 75%; p = 0.004]. Significant differences were also observed in the responses to the theoretical principles, with pregnant women attributing less importance to preserving life at all cost, while being more concerned with physical and emotional pain and suffering, with financial cost, and with the infant's potential for future productivity.

Effects of erythromycin on contractility of isolated myometrium from pregnant rats

OBJECTIVE

Erythromycin is a stimulant of motor activity in the stomach, but its effects on the uterus have not been studied and only its antibiotic properties have been considered in the treatment of idiopathic preterm labor. The objective of this study was to characterize in vitro the effect of erythromycin on the contractility of the pregnant rat uterus.

STUDY DESIGN

Myometrial strips from pregnant rats were suspended in tissue baths Isometric contractions were monitored by force transducers in response to various agents that were added to the bath solution.

RESULTS

Erythromycin exposure caused a sustained decrease in phasic contractions induced by oxytocin or carbachol. This effect started at 0.01 mmol/L. At 1 mmol/L erythromycin reduced the contractions amplitude to 22% of the control and the frequency was reduced to 38% of control.

CONCLUSION

We conclude that erythromycin produces a decrease in the pregnant rat myometrial activity in vitro, independent of the stimulant.

Ultrasonographic endometrial changes after intrauterine insemination: a comparison of two catheters

OBJECTIVE

To determine and compare the transvaginal ultrasonographic (US) endometrial changes immediately after IUI using the Edwards Wallace (H.G. Wallace, Limited, Colchester, Essex, UK) and Tom-Cat (Sherwood Medical, St. Louis, MO) catheters.

DESIGN

Prospective study.

SETTING

IVF unit.

PATIENT(S) AND INTERVENTION(S)

Eighty-two infertile patients underwent 112 cycles of ovulation induction with IUI. Either the Edwards Wallace catheter (group 1, n = 32) or the Tom-Cat catheter (group 2, n = 80) was used for sperm insemination. The presence of an endometrial three-layer pattern before IUI was a prerequisite for inclusion in the study. After each IUI, the endometrium was reassessed by transvaginal US.

MAIN OUTCOME MEASURE(S)

Ultrasonographic endometrial changes, clinical pregnancy rates (PRs), complications, and patients' complaints were compared between the two groups.

RESULT(S)

Total destruction of the endometrial three-layer pattern was observed in 12.5% of the cycles in group 1, compared with 50% of the cycles in group 2. Clinical pregnancies occurred in 14 (12.5%) of the 112 IUI cycles. A higher PR was achieved when the endometrial three-layer pattern was preserved after IUI. The patients in group 2 had more complaints of bleeding and pain during the procedure.

CONCLUSION(S)

Ultrasonographic changes after IUI suggest that the Edwards Wallace catheter is significantly less traumatic to the endometrium than the Tom-Cat catheter. Although both catheters yielded the same overall PR, there was a trend indicating that sparing the endometrial three-layer pattern from damage increases the chance of conception.

Decision-making in the critically ill neonate: cultural background v individual life experiences

OBJECTIVES

In treating critically ill neonates, situations occasionally arise in which aggressive medical treatment prolongs the inevitable death rather than prolonging life. Decisions as to limitation of neonatal medical intervention remain controversial and the primary responsibility of the generally unprepared family. This research was designed to study response patterns of expectant mothers towards treatment of critically ill and/or malformed infants.

DESIGN/SETTING

Attitudes were studied via comprehensive questionnaires divided into three sections: 1-Sociodemographic data and prior personal experience with perinatal problems; 2-Theoretical philosophical principles used in making medical ethical decisions; and 3-Hypothetical case scenarios with choices of treatment options.

SUBJECTS AND RESULTS

Six hundred and fifty pregnant women were studied. Maternal birthplace (p = 0.005) and level of religious observance (p = 0.02) were strongly associated with the desire for maximally aggressive medical intervention in the hypothetical case scenario. Specific personal experiences such as infertility problems, previous children with serious mental or physical problems were not correlated with the selection of different treatment choices. Of the theoretical principles studied, only the desire to preserve life at all costs was significantly associated with the choice for maximal medical treatment (p = 0.003).

CONCLUSIONS

Maternal ethnocultural background and philosophical principles more profoundly influenced medical ethical decision-making than did specific personal life experiences.
