Association of hysterectomy and invasive epithelial ovarian and tubal cancer: a cohort study within UKCTOCS.

OBJECTIVE: To investigate the association between hysterectomy with conservation of one or both adnexa and ovarian and tubal cancer. DESIGN: Prospective cohort study. SETTING: Thirteen NHS Trusts in England, Wales and Northern Ireland. POPULATION: A total of 202 506 postmenopausal women recruited between 2001 and 2005 to the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) and followed up until 31 December 2014. METHODS: Multiple sources (questionnaires, hospital notes, Hospital Episodes Statistics, national cancer/death registries, ultrasound reports) were used to obtain accurate data on hysterectomy (with conservation of one or both adnexa) and outcomes censored at bilateral oophorectomy, death, ovarian/tubal cancer diagnosis, loss to follow up or 31 December 2014. Cox proportional hazards regression models were used to assess the association. MAIN OUTCOME MEASURES: Invasive epithelial ovarian and tubal cancer (WHO 2014) on independent outcome review. RESULTS: Hysterectomy with conservation of one or both adnexa was reported in 41 912 (20.7%; 41 912/202 506) women. Median follow up was 11.1 years (interquartile range 9.96-12.04), totalling >2.17 million woman-years. Among women who had undergone hysterectomy, 0.55% (231/41 912) were diagnosed with ovarian/tubal cancer, compared with 0.59% (945/160 594) of those with intact uterus. Multivariable analysis showed no evidence of an association between hysterectomy and invasive epithelial ovarian/tubal cancer (hazard ratio 0.98, 95% CI 0.85-1.13, P = 0.765). CONCLUSIONS: This large cohort study provides further independent validation that hysterectomy is not associated with alteration of invasive epithelial ovarian and tubal cancer risk. These data are important both for clinical counselling and for refining risk prediction models. TWEETABLE ABSTRACT: Hysterectomy does not alter risk of invasive epithelial ovarian and tubal cancer.

Risk of epithelial ovarian cancer in asymptomatic women with ultrasound-detected ovarian masses: a prospective cohort study within the UK collaborative trial of ovarian cancer screening (UKCTOCS).

OBJECTIVE: To estimate the risk of primary epithelial ovarian cancer (EOC) and slow growing borderline or Type I and aggressive Type II EOC in postmenopausal women with adnexal abnormalities on ultrasound. METHODS: This was a prospective cohort study in the ultrasound group of the UK Collaborative Trial of Ovarian Cancer Screening of postmenopausal women with ultrasound-detected abnormal adnexal (unilocular, multilocular, unilocular solid and multilocular solid, solid) morphology on their first scan. Women were followed up through the national cancer registries and by postal questionnaires. Absolute risks of EOC and borderline, Type I and Type II EOC within 3 years of initial scan were calculated. RESULTS: Of 48 053 women who underwent ultrasound examination and had complete scan data, 4367 (9.1% (95% CI, 8.8-9.3%)) had abnormal adnexal morphology. Median follow-up was 7.09 (25(th) -75(th) centiles, 6.03-7.92) years. Forty-seven (32 borderline or Type I, 15 Type II) were diagnosed with EOC. The overall absolute risk of EOC associated with abnormal adnexal morphology was 1.08% (95% CI, 0.79-1.43%); for borderline and Type I it was 0.73% (95% CI, 0.5-1.03%); and for Type II it was 0.34% (95% CI, 0.33-0.79%). In the subgroup (n = 741) with solid elements (unilocular solid, multilocular solid and solid) overall absolute risk was 4.45% (95% CI, 3.08-6.20%), for borderline and Type I it was 3.1% (95% CI, 1.9-4.6%) and for Type II it was 1.3% (95% CI, 0.6-2.4%). 11 982 women had both ovaries visualized and normal annual scans throughout the 3-year follow-up period. In this group, no borderline or Type I and eight Type II cancers were diagnosed. CONCLUSION: Asymptomatic postmenopausal women with ultrasound-detected adnexal abnormalities with solid elements have a 1 in 22 risk for EOC. Despite the higher prevalence of Type II EOC, the risk of borderline or Type I cancer in women with ultrasound abnormalities seems to be higher than does the risk of Type II cancer. This has important immediate implications for patients with incidental adnexal findings as well as for any future ultrasound-based screening.

Risk of significant gynaecological pathology in women with glandular neoplasia on cervical cytology.

OBJECTIVE: To review the risk of pre-invasive and invasive gynaecological pathology in women referred with cervical cytology reporting ?glandular neoplasia. METHODS: Review of the case notes of all women referred with cervical cytology reported as ?glandular neoplasia between January 1999 and December 2008 at two UK hospitals: Portsmouth Hospitals NHS Trust and Queen Mary's Hospital Sidcup. The category of 'borderline nuclear change in endocervical cells', result code 8 according to the national health service cancer screening programme (NHSCSP), was excluded from the study. RESULTS: A total of 200 women were identified using the hospitals' pathology computer systems. Invasive carcinoma was found in 48 women (24%): 28 endocervical adenocarcinomas, eight squamous cell carcinomas (SCC), ten endometrial and two ovarian adenocarcinomas. Pre-invasive neoplasia was found in 115 (57.5%), including 14 cervical glandular intraepithelial neoplasia (CGIN), 31 cervical intraepithelial neoplasia (CIN) grade 2/3 and 70 concomitant CGIN and CIN2/3. CIN1/HPV was found in 25, simple endometrial hyperplasia in three and no histological abnormality in three. Thirty-four (70.8%) of 48 invasive carcinomas (of which 23 were endocervical adenocarcinomas) were in asymptomatic women investigated for abnormal cytology. Fourteen of 34 (41.4%) of those with ?glandular neoplasia thought to be endometrial were CGIN or CIN2/3. Colposcopic appearances were normal in 47.6% of women with pure cervical glandular neoplasia (adenocarcinoma or CGIN) compared with 12.8% with squamous cell lesions (CIN2/3 or SCC): P = 0.0001. Thus, colposcopy was more sensitive for detecting squamous cell abnormalities than their glandular counterparts. Although cervical adenocarcinomas are less amenable to prevention by screening than cervical SCC, in our study cervical cytology predominantly detected these abnormalities at their early asymptomatic stages. CONCLUSION: At least CIN2 was found in 81.5% in women referred with cervical cytology reporting ?glandular neoplasia. A thorough evaluation of the whole genital tract is needed if colposcopy is negative.

Elevation of multiple serum markers in patients with stage I ovarian cancer.

BACKGROUND: The high overall mortality from ovarian cancer (> 60%) relates, in part, to delays in diagnosis. When ovarian cancer is detected in stage I (International Federation of Gynecology and Obstetrics staging), up to 90% of patients can be cured. Transvaginal sonography can detect early-stage disease with great sensitivity, but it is expensive and lacks specificity. Although serum marker assays could provide a less expensive and more convenient initial screening test, the sensitivity of assays varies. Measurement of serum CA 125 in conjunction with ultrasound screening as a second-line test confers high specificity but detects only about one half of early stage ovarian carcinomas. PURPOSE: The purpose of this retrospective study was to determine whether assays of multiple serum markers would improve sensitivity by detecting a higher percentage of stage I ovarian cancers than the CA 125 assay alone. METHODS: Using immunoradiometric assays, we measured preoperative serum levels of CA 125 tumor-associated antigen, macrophage colony-stimulating factor (M-CSF), and OVX1 in 46 patients with stage I ovarian cancer of different histologies and 237 patients with benign pelvic masses. We also assayed sera from 204 apparently healthy women who had participated in a screening trial and remained free from cancer at 1 year of followup. All specimens were obtained from cryopreserved aliquots. Marker levels were considered to be elevated when levels of CA 125 were greater than 30 U/mL, M-CSF levels were greater than 3.1 ng/mL, or OVX1 levels were greater than 12.1 U/mL. RESULTS: At least one of the serum markers was elevated in 98% of patients with stage I ovarian cancer; CA 125 levels were elevated in 67%. By the same criteria, 11% of healthy individuals and 51% of patients with benign pelvic masses had at least one elevated marker value. Thus, the sensitivity of the combination of assays for the three serum markers was significantly greater than the sensitivity of the CA 125 assay (P < .0005) and specificity was moderate. CONCLUSION: A panel of these three tumor markers can identify early-stage ovarian cancer with extremely high sensitivity and moderate specificity. IMPLICATIONS: Elevation of one or more serum markers should be evaluated further as an indication for transvaginal sonography in apparently healthy women. Such a strategy might substantially reduce the expense and improve the specificity of screening compared to the use of ultrasound alone. Prospective studies with a large cohort of patients at high risk for ovarian cancer will be required to confirm these findings.

Ovarian cancer identified through screening with serum markers but not by pelvic imaging.

Woolas RP, Oram DH, Jeyarajah AR, Bast RC Jr, Jacobs IJ. Ovarian cancer identified through screening with serum markers but not by pelvic imaging. This study evaluated the possible role of 3 additional tumor markers to CA 125 among postmenopausal volunteers participating in a sequential multimodal ovarian cancer screening study. In 82 asymptomatic women the finding of a serum CA 125 level of > 30 U/ml precipitated pelvic ultrasound examination. Levels of CA15-3, CA72-4 and CA19-9 were subsequently determined in sera stored from the time of the CA 125 assay. Following ultrasound 29 women underwent surgery for benign conditions. The remaining 53 women underwent 2 years of surveillance. In 5 of these women a diagnosis of ovarian cancer was established between 6 and 10 months after their initial investigation. Elevated levels of at least one of the 3 additional tumor markers were present in the serum, prior to ultrasound abnormalities being detected, in 4 (80%) of the women who developed cancer. At least one of this 3-marker panel was elevated in 29% of the 48 women who have not developed cancer and 14% of the 29 women undergoing surgery for benign conditions. Information complementary to pelvic ultrasound examination for the preclinical detection of ovarian cancer could be obtained through multiple marker assay. Coordinated elevated serum levels of tumor markers could increase the sensitivity of this sequential screening protocol.

Mixed serous-endometrioid carcinoma of the uterus: pathologic and cytopathologic analysis of a high-risk endometrial carcinoma.

A review of the pathology and cytopathology of 295 endometrial adenocarcinomas treated surgically at King Edward Memorial Hospital for Women, with full 5-year follow-up, revealed 16 cases of pure serous carcinoma (USC), 10 cases of mixed serous and endometrioid carcinoma with a predominant serous component (mixed USC-EAC) and six cases of mixed serous and endometrioid carcinoma with a predominant endometrioid component (mixed EAC-USC). The mixed carcinomas may be characterized microscopically by classical serous features side by side with classical endometrioid features, or additionally by features intermediate between the two. Many of these features are reproduced in preoperative cervicovaginal smears. USC and mixed USC-EAC were found to be indistinguishable clinically and prognostically, with an identical corrected 5-year survival of 40%, although numbers are small. Mixed EAC-USC (which contained 10-25% serous differentiation in this series), however, were similar in many respects to a control population of 95 EAC of Grade 2 and 3. The corrected 5-year survival in these two groups was 67% and 79%, respectively, which is not statistically significant in this small series. This study suggests that the behavior of a mixed tumor containing 50% or more serous differentiation is similar to that of pure serous carcinoma, and that the behavior of a mixed tumor containing less than 25% serous differentiation is similar to that of the other component. Given the poor correlation between pathologic findings in curettage and subsequent hysterectomy specimens, however, identification of any significant serous element in curettage material may prove vital in optimizing surgical and adjuvant therapy.

What is the true incidence of primary fallopian tube carcinoma?

Fallopian tube carcinoma can be histologically indistinguishable from and has a similar clinical behavior to epithelial ovarian carcinoma. However, it is considerably less common; only approximately 1000 cases have been recorded in the literature. In the prevalence screen of 22000 women participating in The Royal London Hospital, London, UK, ovarian cancer screening project, three cases of early stage primary fallopian tube carcinoma were diagnosed following the finding of an elevated serum level of the CA 125 antigen. The ratio of epithelial ovarian : tubal cancer developing in these postmenopausal volunteers was 6:1. This is 25-fold greater than the expected ratio. It is difficult to attribute this finding to population selection bias. However, it is possible that the screening test was particularly effective in detecting tubal carcinoma or that, in clinical practice, the true primary site of origin of some tumors classified as widely disseminated ovarian cancer is in the fallopian tube.

Risk of diagnosis of ovarian cancer after raised serum CA 125 concentration: a prospective cohort study.

OBJECTIVE: To determine the risk of invasive epithelial ovarian cancer and fallopian tube cancer associated with a raised concentration of the tumour marker CA 125 in asymptomatic postmenopausal women. DESIGN: Serum CA 125 concentration was measured annually in study participants for one to four years. Participants with a concentration > or = 30 U/ml were recalled for abdominal ultrasonography. Follow up was by annual postal questionnaire. SETTING: General practice, occupational health departments, ovarian cancer screening unit in a teaching hospital. SUBJECTS: 22,000 volunteers, all postmenopausal women > or = 45 years of age; recruited between 1 June 1986 and 1 May 1990. INTERVENTION: Surgical investigation if the ultrasound examination was abnormal. MAIN OUTCOME MEASURES: Cumulative and relative risk of developing an index cancer (invasive epithelial cancer of the ovary or fallopian tube) after a specified CA 125 result. RESULTS: 49 index cancers developed in the study population during a mean follow up of 6.76 years. The overall cumulative risk of developing an index cancer was 0.0022 for the entire study population and was lower for women with a serum CA 125 concentration < 30 U/ml (cumulative risk 0.0012) but was appreciably increased for women with a concentration > or = 30 U/ml (0.030) and > 100 U/ml (0.149). Compared with the entire study population the relative risk of developing an index cancer within one year and five years was increased 35.9-fold (95% confidence interval 18.3 to 70.4) and 14.3-fold (8.5 to 24.3) respectively after a serum CA 125 concentration > or = 30 U/ml and 204.8-fold (79.0 to 530.7) and 74.5-fold (31.1 to 178.3) respectively after a concentration > or = 100 U/ml. CONCLUSION: CA 125 is a powerful index of risk of ovarian and fallopian tube cancer in asymptomatic postmenopausal women.

Utility of Preoperative CA125 Assay in the Management Planning of Women Diagnosed with Uterine Cancer.

Objective. This study assesses the role of preoperative serum CA125 levels in the planning treatment options for women diagnosed with uterine cancer. Material and Method. Ninety five consecutive patients diagnosed with uterine cancer during a four-year period were identified. Age ranged from 35 to 89 years with a mean age of 69 years. The preoperative CA125 levels were dichotomised at 28 U/mL (using ROC analysis to identify the best discriminating threshold for 5-year survival). This level was then correlated with preoperative prognostic indicators: patient age, tumour grade, and histopathological tumour cell type. Survival data was plotted using Kaplan-Meier curves and analysed using the log-rank test. Univariate and multivariate analysis were performed to identify the predictors of overall survival. Results. The mean age of patients was 69 years (range: 35-89). On univariate analysis, the use of preoperative CA125 levels of greater or less than 28 U/mL correlated significantly with age (P = 0.01), the grade of disease (P = 0.02) and unfavourable tissue type (P = 0.03). This threshold CA125 level had a sensitivity of 75%, specificity of 76%, positive predictive value of 35% and negative predicative value of 96.25%, and a likelihood ratio of 3.12 for predicting nodal disease. Using a threshold of preoperative CA125 level of 28 U/mL (area under curve: 0.60) was also a significant predictor of 5-year survival (log-rank test, P = 0.01). Using Cox multivariate survival analysis to identify predictive preoperative factors overall, unfavourable cell type was the strongest predictor of survival (Chi square = 36.5, df = 4, and P = 0.001), followed by preoperative CA125 level (CA125 > 28 U/mL, P = 0.011) and unfavourable preoperative grade (P = 0.017). Amongst patients with a favourable histological tissue type (endometrioid), preoperative CA125 levels predicted overall survival (Chi square = 6.039, df = 2, P = 0.02); however unfavourable preoperative grade did not (P = 0.5). Overall, at five-year follow-up, while there were no deaths among the women with preoperative serum CA125 less than 12 U/mL, eleven of the twenty-three deaths (47.82%) in the study occurred in women with a preoperative CA125 more than 28 U/mL. Conclusions. A preoperative CA125 assay for women with uterine cancer is a relatively inexpensive, reproducible, and objective test which provides valuable information regarding the risk of metastatic disease and overall likelihood of long term survival. Patients with a low likelihood of metastatic/nodal disease (favourable tissue type and CA125 level < 28 U/mL) and significant comorbidities may benefit from avoiding an extended complete staging procedure. Alternatively, a high level of CA125 may prompt further imaging and multidisciplinary discussions to plan for individualised management and consideration for recruitment to clinical trials.

Utility of sentinel node biopsy in vulvar and vaginal melanoma: report of two cases and review of the literature.

Sentinel node (SN) biopsy is widely applied for treatment planning of cutaneous melanoma. However, using this strategy in female lower genital tract tumors has not yet been established. We report two cases, one each of vulvar and vaginal melanoma who underwent SN biopsy and review the available literature. Our experience and available limited evidence suggests that this low morbidity technique can be used for obtaining prognostic information and hence treatment planning for this disease. However, a false negative rate perhaps in the order of 15% suggests that careful consideration is necessary before using sentinel lymph node biopsy in the management of vulvar and vaginal melanoma.

Uterine papillary serous carcinoma in a 32-year-old with Turner's syndrome.

The association of Turner's syndrome and endometrial carcinoma has been previously established but has never been described in conjunction with a uterine papillary serous carcinoma (UPSC). This histological variant is usually found in considerably older women and has no clear relationship to the prior use of estrogen replacement therapy. Despite presenting with stage IV disease, treated by surgery and medroxyprogesterone only, this patient has had an 8-year disease-free remission, suggesting that radical debulking of an endocrine-responsive tumor may be of considerable benefit to some women with this unfavorable histological subtype of endometrial carcinoma.

The adnexal mass: benign or malignant? Evaluation of a risk of malignancy index.

OBJECTIVE: To validate a risk of malignancy index incorporating menopausal status, serum CA 125 level and pelvic ultrasound features in the pre-operative diagnosis of ovarian cancer. DESIGN: A retrospective observational study. SETTING: Department of Obstetrics and Gynaecology, The Royal London Hospital. SUBJECTS: One hundred and twenty-four women admitted consecutively to the gynaecology department for surgical exploration of an adnexal mass. MAIN OUTCOME MEASURES: The sensitivities and specificities of menopausal status, serum CA 125 level and ultrasound features, in isolation and combined (the risk of malignancy index (RMI)), for diagnosing ovarian cancer. RESULTS: Tested on a new population of women, the RMI retained the high sensitivity for diagnosing ovarian cancer seen in the original report describing its derivation. The specificity, however, was lower. The study confirmed that the RMI is more accurate than the individual criteria in diagnosing ovarian cancer, and was comparable with other scoring systems. CONCLUSIONS: The risk of malignancy index is a simple scoring system for ovarian cancer. Application of the risk of malignancy index in clinical practice may provide a rational basis for specialist referral of patients with ovarian cancer before diagnostic surgery.

Influence of chemotherapy for gestational trophoblastic disease on subsequent pregnancy outcome.

The aim of this study was to determine the influence of cytotoxic chemotherapy on subsequent reproductive performance. Details of post-treatment reproductive intent and outcome were requested from 1211 survivors registered at The Charing Cross Hospital gestational trophoblastic disease centre; a response rate of 96% was achieved. Seven hundred and twenty-eight women had tried to become pregnant; 607 reported at least one live birth, 73 conceived but had not registered a live birth, and 48 did not conceive. No differences were apparent between the 392 women who received methotrexate as single agent chemotherapy and the 336 treated with multi-agent chemotherapy. Women who had registered a live birth were younger (P < 0.0001) and the duration of follow up was significantly less among those who did not achieve pregnancy at all (P < 0.0003). A higher than expected rate of caesarean section and stillbirth was recorded. The chemotherapy protocols used by this unit have minimal impact on the subsequent ability to reproduce.

Investigation of women with endometrial carcinoma using serum vascular endothelial growth factor (VEGF) measurement.

This study assessed whether serum VEGF measurement in women presenting with endometrial cancer could predict advanced stage disease. Preoperative sera from 37 women undergoing laparotomy for suspected endometrial cancer were assayed for VEGF, CA125 and platelet count. Significant positive correlation was shown between VEGF and platelet levels (P = 0.003, r = 0.477). However, no correlation was demonstrated between VEGF and stage overall, and no significant difference was shown between those with early (stage 1A/1B, n = 20) compared to those with advanced (stage >1B, n = 13) or disseminated (stage >2, n = 7) disease. Serum VEGF measurement was not beneficial in the preoperative assessment of stage in patients with endometrial carcinoma. Strong correlation with platelet levels suggests that this is one of the sources of VEGF measured.

Serum CA 125 in a pregnancy generated by ovum donation.

Serum CA 125 was measured by radioimmunoassay during the first trimester at intervals of 2 weeks in a woman with Turner's syndrome, who conceived following ovum donation from a healthy anonymous donor. Serum CA 125 concentrations were lower than or at the 10th percentile of the normal range. These findings imply that CA 125 may be secreted from the ovary in the first trimester, or produced at another site in response to stimuli from the ovary.

Immunocytochemical and serological expression of CA 125: a clinicopathological study of 40 malignant ovarian epithelial tumours.

Elevated serum levels of the tumour-associated antigen CA 125 occur in more than 80% of cases of ovarian carcinoma. The antigen can be demonstrated in formalin-fixed tissue using the monoclonal antibody OC 125, which localizes it to the surface membrane or cytoplasm. This study was performed to determine the relationship between pre-operative serum levels of CA 125 and the subsequent immunocytochemical findings in the surgical specimen. Paraffin-wax embedded sections from 40 consecutive borderline and frankly malignant ovarian epithelial tumours were stained with OC 125. The pattern and distribution of immunostaining were investigated in relation to histological appearances. Serous tumours showed a 100% correlation between immunocytochemical findings and elevated serum levels of CA 125. Amongst the other histological types, correlation was less good; mucinous tumours and undifferentiated carcinomas showed a poor correlation. Immunostaining within tumours was heterogeneous and only loosely related to morphological appearances. Our finding suggests that, with the exception of serous tumours, immunolocalization of CA 125 is insufficiently sensitive to provide reliable clinical guidance to the likely value of serum CA 125 monitoring on follow-up.

Molecular approaches to prevention and detection of epithelial ovarian cancer.

More than 90% of epithelial ovarian cancers arise from single cells. Malignant transformation can be associated with a number of molecular alterations including upregulation of tyrosine kinases and phosphatases, physiologic activation o ras, mutation of p53, amplification of myc, and increased activity of matrix metalloproteinases 2 and 9. Proliferation of transformed epithelial cells can be enhanced through the persistence of autocrine growth stimulation by TGF-alpha, loss of autocrine growth inhibition by TGF-beta, as well as paracrine growth stimulation by macrophage derived cytokines and OCAF, a novel lyso-phospholipid. Ascites tumor cells retain responsiveness to growth inhibition by TGF-beta which induces apoptosis in malignant ovarian epithelial cells, but not in normal ovarian surface epithelium. Proliferation of surface epithelial cells following ovulation may contribute to the pathogenesis of ovarian cancer. Use of oral contraceptives that suppress ovulation has been associated with reduced risk of ovarian cancer in later life. Retinoids also deserve further evaluation for chemoprevention. Treatment with fenretinide was associated with decreased incidence of ovarian cancer. Additive or synergistic inhibition of ovarian tumor cell proliferation has been observed with TGF-beta in combination with all-trans-retinoic acid. Early detection of ovarian cancer could improve survival. Transvaginal sonography (TVS) and serum markers such as CA-125 have been evaluated in multiple clinical trials. The former lacks adequate specificity, whereas the latter is not sufficiently sensitive. Use of multiple serum markers can improve sensitivity. A combination of CA-125, M-CSF and OVX-1 has detected > 95% of Stage I ovarian cancers. If similar results are obtained with different data sets, multiple serum markers could be used to trigger the performance of TVS, providing a potentially cost effective screening strategy. Prospective trials will be required to demonstrate that screening for early stage ovarian actually impacts on survival.

Gastrostomy tubes in patients with recurrent gynaecological cancer and intestinal obstruction.

OBJECTIVE: Women with recurrent gynaecological cancers who are not suitable for exenterative surgery commonly present with gastrointestinal dysfunction. This paper is a retrospective review of the use of gastrostomy tubes in such women. METHODS: We performed a chart review of women with recurrent gynaecological cancer who had a gastrostomy tube placed between January 1991 and April 1998. RESULTS: Thirty-nine women (mean age 53.2 years, range 17-82) had a gastrostomy tube placed. Twenty-eight (72%) had ovarian cancer, eight (21%) had cervical cancer, two had endometrial cancer and one had vaginal cancer. In 14 women a gastrostomy tube was placed as the sole procedure for palliation (11 elective, 3 emergency). In the remaining 25 women, who underwent major surgery, a gastrostomy tube was placed in anticipation of, or in the presence of, significant intestinal distension and expected prolonged post-operative ileus. Eleven women (28%) died without leaving hospital after their operation (median 11 days, range 2-36). All but one of the 28 women who left hospital had satisfactory oral intake. Twenty-one women (54%) died with the gastrostomy tube in place (median 28 days, range 2-157) and 18 (46%) had the gastrostomy tube removed (median 14.5 days, range 9-180), 13 of whom (33%) have since died (median 167 days, range 77 days-7 years). Five women (13%) are alive (median 2.2 years, range 10 months-4.5 years). There were no problems which required the gastrostomy tube to be removed. CONCLUSION: Gastrostomy tubes have an important role in the treatment of women with recurrent gynaecological cancer, allowing gastric drainage and decompression without the disadvantages of nasogastric tubes.

Role of MR imaging in the selection of patients with early cervical carcinoma for fertility-preserving surgery: initial experience.

PURPOSE: To assess whether magnetic resonance (MR) imaging can be used for reliable prediction of proximal extension of cervical carcinoma into the myometrium. MATERIALS AND METHODS: Thirty patients with early cervical carcinoma underwent MR imaging with use of a 1.5-T magnet prior to surgery. The MR images were analyzed by two radiologists, unaware of the histopathologic findings, for the relationship of the tumor to the internal os and extension of the tumor into the myometrium. Findings at MR imaging were compared with those at histopathologic examination. RESULTS: At MR imaging, 24 patients were considered not to have tumor extension proximal to the internal os and into the myometrium. All tumors were confirmed histopathologically. In six patients thought to have myometrial tumor invasion at MR imaging, five tumors were confirmed histopathologically; in one, tumor extended up to the internal os but did not involve the myometrium. CONCLUSION: This is a small study, but MR imaging appears accurate in the prediction of myometrial tumor involvement and in showing the relationship of cervical carcinoma to the internal os and, hence, the patient's suitability for trachelectomy.
