Malnutrition among gynaecological cancer patients.

OBJECTIVE: To assess the nutritional status of patients with gynaecological cancer. DESIGN: A prospective study assessing the nutritional status of gynaecological patients with suspected or proven gynaecological cancer. SETTING: Queensland Centre for Gynaecological Cancer, Brisbane, Australia; a tertiary referral centre for gynaecological cancer. SUBJECTS: One hundred forty-five patients with suspected or proven gynaecological cancer aged 20-91 years. INTERVENTION: Scored patient-generated subjective global assessment (PG-SGA) and serum albumin before treatment. RESULTS: One hundred and sixteen (80%) patients were categorized as PG-SGA class A, 29 (20%) patients were PG-SGA B and none of the patients were PG-SGA C. Ovarian cancer patients had significantly lower serum albumin levels (P=0.003) and higher PG-SGA scores (P<0.001) than patients with other types of cancer and benign conditions. Sixty-seven per cent of patients with ovarian cancer were classified as PG-SGA B. After adjusting for patient's age, body mass index and albumin level, ovarian cancer patients were 19 times more likely to be categorized as PG-SGA class B compared to patients with benign conditions (95% confidence interval: 3.03-129.8; P=0.002). CONCLUSION: Malnutrition in gynaecological cancer patients is a significant problem, especially among those patients diagnosed with ovarian cancer.

Total laparoscopic versus open surgery for stage 1 endometrial cancer: the LACE randomized controlled trial.

PURPOSE: Endometrial cancer is the most common gynaecological malignancy in Australia and the US. Current standard treatment involves open surgery to remove the uterus, and both tubes and ovaries (TAH). The Laparoscopic Approach to Cancer of the Endometrium (LACE) trial was designed to assess equivalence of performing this in a total laparoscopic approach (TLH). METHODS: Patient recruitment was designed to proceed along two stages to accommodate for a potential increase in patient requests of laparoscopic surgery. During the first stage, patients are randomised in a 2:1 allocation to receive TLH or TAH, with the primary endpoint quality of life (QoL) at 6 month post-surgery, requiring 180 patients to be enrolled to have 80% power at alpha=0.05 to detect a clinically significant difference of 8 points on the Functional Assessment of Cancer General (FACT-G) QoL instrument. If additional recruitment of patients seems impossible after accrual of 180 patients, this cohort will be followed for 4 years, and disease free survival (DFS) of patients treated by TLH will be compared to DFS within the endometrial cancer population. During the second stage, recruitment will be extended to a total of 590 patients in a 1:1 TLH:TAH allocation, to assess the equivalence with respect to DFS with 80% power and alpha=0.05. Equivalence will be assumed if the difference in DFS does not exceed 7% at 4 years. Secondary outcomes include treatment related morbidity; costs and cost-effectiveness; patterns of recurrence; and overall survival. All data from this multicentre study will be entered using online electronic case report forms (e-CRF), allowing real time assessment of data completeness and patient follow-up. CONCLUSIONS: The LACE trial will establish the equivalence of a TLH approach for patients with stage 1 endometrial cancer following a two stage protocol to accommodate potential threats to patient recruitment through requests for laparoscopic surgery.

Small-cell carcinoma of the uterus and the vagina: experience with ten patients.

BACKGROUND: Small cell carcinomas (small-CCs) of the uterine cervix are rare and highly malignant neoplasms. Patients tend to develop distant metastasis early and thus are potential candidates for systemic therapy. We reviewed the experience with small-CCs of the uterus and vagina at two Austrian University hospitals. MATERIAL AND METHODS: Ten patients (median age, 50 years; range, 18-92) with small-CC of the cervix (n=7), uterine corpus (n=2), and the vagina (n=1) were treated at the two centers between 1988 and 1998. Eight patients underwent radical surgery, 7 of whom also received chemotherapy. Two additional patients underwent primary radiotherapy. RESULTS: All Pap smears were suspicious for cervical malignancy. The median survival was 12 months (range, 6-86) and overall 5-year survival was 10%. Five of 8 surgically treated patients had lymph node involvement (62%). Of the 7 patients with small-CC of the cervix only one, who had FIGO stage IIB disease and positive pelvic nodes, survived long-term (86 months) with no evidence of disease. She had received six courses of dose-intensive platinum chemotherapy after radical surgery. All three patients with small-CC of the uterine corpus or vagina developed recurrence within the first year after diagnosis. Of the 7 patients who received chemotherapy, 5 developed progressive or recurrent disease in the paraaortic region (n=2), peritoneum (n=1), liver (n=1), or pelvis (n=1). CONCLUSION: These results confirm the particularly unfavorable prognosis of patients with small-CC of the genital tract. The optimal treatment for these patients most probably including concurrent chemo-radiotherapy remains to be defined.

Lack of impact of platinum dose intensity on the outcome of ovarian cancer patients. 10-year results of a prospective randomised phase III study comparing carboplatin-cisplatin with cyclophosphamide-cisplatin.

This prospective multicentre phase III trial was conducted to assess whether increased platinum dose intensity (DI) by combining carboplatin with cisplatin has an impact on overall survival (OS) and progression-free interval (PFI) compared with the standard combination of cyclophosphamide and cisplatin in patients with epithelial ovarian cancer. A total of 253 patients with epithelial ovarian cancer of stages International Federation of Gynecology and Obstetrics (FIGO) IC-IV were randomised to receive either cyclophosphamide (600 mg/m(2), intravenously (i.v.), day 1) and cisplatin (100 mg/m(2), i.v., day 2) (n=125) as the standard regimen or carboplatin (300 mg/m(2), i.v., day 1) and cisplatin (100 mg/m(2), i.v., day 2) (n=128), every 28 days for six courses. The median follow-up was 6.0 years. 124 patients randomised to the platinum dose-intensified arm and 123 patients randomised to the standard arm met all of the eligibility criteria. Patient characteristics were well balanced between the two treatment groups. All eligible patients randomised were included in the analysis of OS and PFI. The median OS of the standard and platinum dose-intensified arms were 41.2 (95% Confidence Interval (CI): 29.2-50.7) and 43.0 months (95% CI: 34.3-63.2), respectively (P=Non-significant (N.S.). The median PFI in the standard arm was 29.7 (95% CI: 17.4-41.7) versus 23.1 months (95% CI: 17.8-35.4) in the platinum dose-intensified arm, respectively (P=N.S.). Toxicity, comprising leucopenia, granulocytopenia, thrombocytopenia, anaemia, emesis and nausea, was statistically significantly higher in the platinum dose-intensified arm than in the standard arm. Unexpectedly, no statistically significant differences were found between the 2 arms' overall neuro- and ototoxicity. When converting carboplatin-platinum into cisplatin-platinum on the basis of an equivalence ratio of 4:1, patients in the platinum dose-intensified arm received a total platinum dose 1.58 times the platinum dose of the standard arm. With 35.0 mg/m(2)/week being administered, the total platinum DI of the dose-intensified arm was statistically significantly (P<0.0001) higher than that of the standard regimen (with 22.0 mg/m(2) being administered). Calculating the average administered relative dose intensities of the regimens yielded almost identical results with 0.56 and 0.58 for the standard and experimental arms, respectively. Thus, by conventional means, a 1.6-fold increase in the platinum DI could be reached by combining carboplatin and cisplatin without unacceptable morbidity. Nevertheless, this did not translate into any therapeutic benefit for the patient, even in the optimally debulked group of patients for whom dose-intensification would have been expected to be of benefit.

The Western Australian experience of the use of en bloc resection of ovarian cancer with concomitant rectosigmoid colectomy.

OBJECTIVES: The aim of this study was to assess the technique of en bloc resection of ovarian cancer with concomitant rectosigmoid colectomy, in relation to perioperative complication rates, and its impact on survival following the procedure. METHODS: A retrospective review was performed of the case notes of 129 consecutive procedures performed between 1989 and 2000 in a regional cancer center. RESULTS. Overall, 48.8% of patients suffered a major or minor complication. Complications relating to bowel anastomosis occurred in 2.4%. Perioperative mortality was 3.1%. Median survival for the group as a whole was 30.6 months. Patients who were optimally debulked had a significantly longer median survival time. CONCLUSION: En bloc resection of ovarian cancer with concomitant rectosigmoid colectomy allows a high rate of optimal debulking with acceptable morbidity, mortality, and survival.

Analysis of the human progesterone receptor gene polymorphism progins in Austrian ovarian carcinoma patients.

Ovarian carcinoma is the highest death cause in gynecologic malignancies. Although the molecular basis for familial breast and ovarian cancer is elucidated, few genetic markers have been associated with sporadic ovarian carcinoma. A polymorphism in intron G of the human progesterone receptor (PgR), caused by an Alu insertion, was described to be associated with ovarian carcinoma in a pooled German/Irish population. Later on, a G to T substitution in exon 4, causing a Valine to Leucine change in the hinge region of the receptor, and a synonymous C to T substitution in exon 5 were reported to be linked to the Alu insertion. This complex of the PgR gene polymorphism was designated PROGINS. In order to investigate if PROGINS is associated with risk for ovarian cancer in Austrian women, we analyzed DNA from 226 Austrian patients with sporadic ovarian carcinoma and a control group with 194 healthy volunteers for the PROGINS complex. The PROGINS status was studied in association with risk for ovarian carcinoma, the age of the ovarian patients, the protein level of PgR and estrogen receptor (ER) and histopathological parameters. The results indicate that the frequency of PROGINS carriers in Austrian women is similar to those in women in North America and England. There is no significant difference between the PROGINS allele distribution in ovarian carcinoma patients and healthy women. The PROGINS is not associated with increased risk for ovarian carcinomas. Additionally, the protein levels of ER and PgR were independent of the PROGINS status.

Impact of hemoglobin levels before and during concurrent chemoradiotherapy on the response of treatment in patients with cervical carcinoma: preliminary results.

BACKGROUND: In patients undergoing radiation for cervical carcinoma, there is evidence that anemia is associated with an impaired outcome. For patients undergoing chemoradiation, there are no data available. The objective of this retrospective study was to examine the impact of anemia before and during chemoradiation in patients with cervical carcinoma. METHODS: The authors collected data on hemoglobin (Hb) levels before and during treatment from 57 patients with cervical carcinoma. The stage of disease ranged between Stage IB and Stage IVA. All patients were treated with concurrent chemoradiation. Response to chemoradiation was evaluated by univariate and multivariate analyses. RESULTS: The mean Hb level at the time of presentation was 12.9 +/- 1.6 g/dL in patients with a complete clinical response (CCR) and 12.1 +/- 1.4 g/dL in those with persistent disease (P = 0.126). In patients with a CCR, the mean nadir Hb level was 11.1 +/- 1.3 g/dL, and in patients with treatment failure, it was 9.8 +/- 1.8 g/dL (P = 0.008). A univariate logistic regression model demonstrated that the nadir Hb level was the most predictive factor for treatment failure (relative risk, 1.92; P = 0.015) followed by disease stage (relative risk, 0.51; P = 0.074). In a multivariate model, the nadir Hb level remained the only prognostically relevant factor predicting the response to chemoradiation. Only patients with nadir Hb values > 11 g/dL throughout chemoradiation had a more than 90% chance of achieving a CCR. CONCLUSIONS: In patients undergoing chemoradiation for cervical carcinoma, the nadir Hb level is highly predictive of response to treatment, whereas the Hb level at the time of presentation is prognostically not significant.

Overexpression of Id-1 protein is a marker for unfavorable prognosis in early-stage cervical cancer.

Inhibitor of differentiation/DNA binding (Id) proteins are transcription factors, involved in cell cycle regulation and neoangiogenesis. Using immunohistochemistry, we investigated the prognostic influence of Id-1, Id-2, and Id-3 expression in 89 patients with cervical cancer stage pT(1b). In univariate and multivariate analysis, patients with strong or moderate expression of Id-1 had a significant shorter overall survival time (P = 0.0144, log-rank test) and disease-free survival time (P = 0.0107, log-rank test) compared with those with low or absent Id-1 expression. Id-1 expression is an independent prognostic marker in early-stage cervical cancer.

Peritoneal cytology: impact on disease-free survival in clinical stage I endometrioid adenocarcinoma of the uterus.

The prognostic significance of positive peritoneal cytology in endometrial carcinoma has led to the incorporation of peritoneal cytology into the current FIGO staging system. While cytology was shown to be prognostically relevant in patients with stage II and III disease, conflicting data exists about its significance in patients who would have been stage I but were classified as stage III solely and exclusively on the basis of positive peritoneal cytology (clinical stage I). Analysis was based on the data of 369 consecutive patients with clinical stage I endometrioid adenocarcinoma of the endometrium. Standard treatment consisted of an abdominal total hysterectomy, bilateral salpingo-oophorectomy with or without pelvic lymph node dissection. Peritoneal cytology was obtained at laparotomy by peritoneal washing of the pouch of Douglas and was considered positive if malignant cells could be detected regardless of the number of malignant cells present. Disease-free survival (DFS) was considered the primary statistical endpoint. In 13/369 (3.5%) patients, positive peritoneal cytology was found. The median follow-up was 29 months and 15 recurrences occurred. Peritoneal cytology was independent of the depth of myometrial invasion and the grade of tumour differentiation. Patients with negative washings had a DFS of 96% at 36 months compared with 67% for patients with positive washings (log-rank P<0.001). The presence of positive peritoneal cytology in patients with clinically stage I endometrioid adenocarcinoma of the endometrium is considered an adverse prognostic factor.

Lymphatic microvessel density as a novel prognostic factor in early-stage invasive cervical cancer.

Few data on the influence of lymphatic microvessel density (MVD) on survival in cancer are available since until recently there was no reliable immunohistological marker for lymphatic endothelium. Using an antibody staining podoplanin, a novel marker for lymphatic endothelium, lymphatic MVD in tissue samples of 85 patients with cervical cancer classification pT1b treated by radical hysterectomy was investigated. Survival was determined using univariate and multivariate analyses. Lymphatic MVD was also compared to MVD assessed by immunostaining against factor VIII-related antigen, which is considered a marker for blood vessels. Patients with >5 lymphatic microvessels/0.25 mm(2) field had significantly better overall survival (mean 91.8 months) than those with < or =5 lymphatic microvessels/field in univariate analysis (mean 113 months) (p = 0.0105, log-rank test). In multivariate analysis, lymphatic node involvement (p =0.0183), vessel infiltration (p =0.0158) and lymphatic MVD (p =0.0269) remained independent prognostic factors. No correlation between lymphatic MVD and various clinical and histopathological parameters was observed. Correlation between lymphatic MVD and MVD assessed by immunostaining against factor VIII was only weak (p = 0.004, r = 0.312, Spearman's coefficient of correlation). Our results suggest that increased lymphatic MVD is associated with favorable prognosis in early-stage cervical cancer.

Concentration of vascular endothelial growth factor (VEGF) in the serum of patients with malignant bone tumors.

BACKGROUND: Vascular endothelial growth factor (VEGF) is recognized as an important stimulator of angiogenesis. Formation of new blood vessels by angiogenic factors occurs in many biological processes, both physiological and pathological, among others in growth of primary solid malignant tumors and metastasis. This implies that the inhibition of angiogenic factors like VEGF would result in a suppression of tumor growth and metastasis formation. The aim of the present study was to compare preoperative serum VEGF levels of patients having malignant bone tumors with healthy controls to identify serum VEGF levels as a tumor marker. PROCEDURE: Blood sera from patients with high-grade osteosarcoma (n = 17), chondrosarcoma (n = 4) and Ewing sarcoma (n = 6) were taken at the time of diagnosis before biopsy and compared with sera from 129 healthy persons. To measure VEGF levels in serum, a commercially available ELISA was used (Quantikine Human VEGF Immunoassay; R&D Systems). RESULTS: The observed geometric mean VEGF levels and 95% confidence intervals are 232.0 pg ml(-1) (168.9-318.5) for patients with high-grade osteosarcoma, 325.5 pg ml(-1) (169.3-625.8) for patients with chondrosarcoma, 484.3 pg ml(-1) (284.0-826.0) for patients with Ewing sarcoma, as compared to 216.2 pg ml(-1) (192.8-242.5) for healthy individuals. CONCLUSIONS: While the sample means for the three groups of sarcoma patients were higher than the respective mean for the healthy controls, only the mean for the group with Ewing sarcoma is statistically significantly higher than the mean for the healthy controls. Despite the significant difference, VEGF levels are not suitable as a marker for Ewing sarcoma.

Prognostic parameters in endometrial stromal sarcoma: a clinicopathologic study in 31 patients.

OBJECTIVE: The aim of this study was to evaluate the behavior of endometrial stromal sarcomas (ESS) in relation to their clinical and pathologic features and to identify possible prognostic factors. METHODS: Thirty-one patients with histologically proven ESS were included in the analysis. Endometrial stromal sarcoma is characterized by proliferations composed of cells with endometrial stromal cell differentiation. A breakpoint of 10 mitoses per 10 high-power fields was used in the statistical analysis to distinguish between low-grade and high-grade endometrial stromal sarcoma and to evaluate the prognostic value of mitotic count in patients with ESS. RESULTS: The median follow-up time was 72 months (range 34-110). The median overall survival of the 31 patients was 127 months, resulting in a 5-year overall survival rate of 62%. Adjuvant therapy was administered to 25 patients; among those, 20 patients received postoperative radiotherapy and 5 patients received chemotherapy. Ten of the irradiated patients and 3 patients undergoing chemotherapy developed disease recurrence. Concerning the response rate to adjuvant chemotherapy, 1 patient showed a complete response, 1 patient a partial response, 1 patient stable disease, and 2 patients progressive disease. Altogether, 14 patients developed recurrent disease with a median disease-free survival of 11 months (range 5-60). Twelve patients died of the disease. A univariate model revealed that early tumor stage (P < 0.0007), low myometrial invasion (P < 0.008), and low mitotic count (P < 0.005) were associated with a lengthened overall survival in patients with endometrial stromal sarcoma. Age and adjuvant therapy did not influence overall survival of patients with ESS. CONCLUSION: Early tumor stage, low myometrial invasion, and low mitotic count are associated with a lengthened overall survival in patients with ESS.

The significance of psammoma bodies on cervical cytology smears.

OBJECTIVE: The association between psammoma bodies on cervical smear (PBCS) and the presence of gynecological malignancy has been documented previously. The aim of this study was to determine the incidence of malignancy where psammoma bodies were detected on smear, to identify features that may be predictive of associated malignancy, and to make recommendations about management. METHODS: The databases of two large private pathology laboratories were accessed to obtain details of all patients reported to have PBCS between April 1992 and May 2000. A retrospective review was then undertaken to determine if any patients were found to have gynecological malignancies. The appearances of the background cells on the cervical smear and details of clinical management were recorded and evaluated. RESULTS: Twenty-two patients were found to have PBCS. Five patients were found to have a gynecological malignancy. These five patients were significantly older than the remaining patients. When these results were combined with all cases reported in the world literature, it became apparent that patients with coexisting malignancy were statistically significantly older than those not found to have malignancy (P < 0.0001). The cytological appearance of cells on the background smear was highly predictive of the presence or absence of malignancy. CONCLUSIONS: There is an association between PBCS and genital tract malignancy. This association is much stronger for postmenopausal women. The background cytology is highly predictive of the presence of associated malignancy. There is a strong argument that all women with psammoma bodies on cervical smear should undergo smear review, pelvic ultrasonography, hysteroscopy and biopsy, and laparoscopy to exclude the presence of a gynecological malignancy. For younger reproductive-aged women, a negative workup is reassuring.

Safety and efficacy of low anterior en bloc resection as part of cytoreductive surgery for patients with ovarian cancer.

OBJECTIVE: To examine the feasibility and safety of a low anterior resection of the rectosigmoid plus adjacent pelvic tumour as part of primary cytoreduction for ovarian cancer. METHODS: This study included 65 consecutive patients with primary ovarian cancer who had debulking surgery from 1996 through 2000. All patients underwent an en bloc resection of ovarian cancer and a rectosigmoid resection followed by an end-to-end anastomosis. Parameters for safety and efficacy were considered as primary statistical endpoints for the aim of this analysis. RESULTS: Postoperative residual tumour was nil, <1 cm, and >1 cm in 14, 34, and 14 patients, respectively. The median postoperative hospital stay was 11 days (range, 6 to 50 days). Intraoperative complications included an injury to the urinary bladder in one patient. Postoperative complications included wound complications (n = 14, 21.5%), septicemia (n = 9, 13.8%), cardiac complications (n = 7, 10.8%), thromboembolic complications (n = 5, 7.7%), ileus (n = 2, 3.1%), anastomotic leak (n = 2, 3.1%), and fistula (n = 1, 1.5%). Reasons for a reoperation during the same admission included repair of an anastomotic leak (n = 1), postoperative hemorrhage (n = 1), and wound debridement (n = 1). Wound complications, septicemia, and anastomotic leak formation were more frequent in patients who had a serum albumin level of < or =30 g/L preoperatively. There was one surgically related mortality in a patient who died from a cerebral vascular accident 2 days postoperatively. CONCLUSIONS: An en bloc resection as part of primary cytoreductive surgery for ovarian cancer is effective and its morbidity is acceptably low.

Novel MUC1 splice variants are expressed in cervical carcinoma.

OBJECTIVES: The MUC1 antigen can be used to identify epithelial cells from the background of hemopoietic cells. The present investigation describes patterns of overexpression of two novel MUC1 splice variants in human cervical carcinoma cell lines. METHODS: RT-PCR was carried out to determine MUC1 splice variants in the cervical cancer cell lines C-4 II, C-33A, DoTc 2 4510, C-4 I, SiHa, HT3, Hs 636 T (C4-I), and HeLa. RESULTS: The novel MUC1 splice variant D was expressed in all cell lines and the novel MUC1 splice variant C was expressed in all cell lines but C-33A. Variants A and B were expressed in all (variant A) and all but one (variant B) cell line. MUC1/REP was expressed in all cell lines and MUC1/SEC was positive in all but two cell lines (C-33 A, DoTc 2 4510). All but one cell line (C-33A) expressed MUC1/X and MUC1/Y, and two cell lines (C-33 A, DoTc 2 4510) did not express MUC1/Z, respectively. MUC1 variants A, D, and REP could be demonstrated consistently among all eight cervical carcinoma cell lines we have examined. CONCLUSIONS: The present study describes the feasibility of detecting a large number of MUC1 variants, including MUC1 variants C and D which are described for cervical carcinoma cells for the first time. Further studies will examine the presence of MUC1 splice variants' expression in human cervical carcinoma tissue.

Increased microvessel density in adenomyosis uteri.

OBJECTIVE: To investigate microvessel density in adenomyosis compared to the endometrium in patients with adenomyosis and in normal controls. DESIGN: Uterine paraffin-embedded histologic specimens were immunostained for CD34. The area with the highest microvessel density in adenomyosis and in the endometrium was evaluated. All microvessels in a specific field of view (x200 magnification) were counted. SETTING: The Department of Gynecological Endocrinology and the Institute of Clinical Pathology, Department of Gynecopathology, in an university hospital. PATIENT(S): Specimens of 53 patients with adenomyosis, who had undergone hysterectomy. Endometrial specimens of 17 women without uterine pathology were investigated as normal controls. MAIN OUTCOME MEASURE(S): Microvessel density in adenomyosis and in the endometrium. RESULT(S): The mean microvessel density was significantly higher in adenomyosis than in the endometrium of the same patients (33.5 +/- 14.6 vs. 19.5 +/- 12.5 microvessels/field; P<.001 sign test). No significant difference between the endometrium of patients and of normal controls was observed (P=.805). CONCLUSION(S): Adenomyosis exhibits angiogenic properties. However, the endometrium of patients with adenomyosis is not more prone to express angiogenic activity compared to the endometrium of normal controls.

Three-dimensional ultrasound of the female urethra: comparing transvaginal and transrectal scanning.

OBJECTIVES: To compare transvaginal and transrectal three-dimensional ultrasound in determining the morphology and measurements of the female urethra. DESIGN: Sixty-five women who had not had surgery for incontinence or pelvic floor descent had transvaginal and transrectal sonography using a 7.5-MHz mechanical sector endoprobe with three-dimensional facilities. The multiplanar display of the scanned volumes allowed detailed morphologic assessment of the urethra and the measurement of distances and volumes. Statistical endpoints were: sagittal urethral diameter, maximum rhabdosphincter length and thickness, maximum thickness of the smooth muscle complex, and the volumes of the rhabdosphincter and the smooth muscle complex. Values were compared between the two approaches using Student's t-test and Bland-Altman analysis. RESULTS: Both vaginal and rectal scans were feasible. However, significant differences between the two approaches were found for the sagittal diameter of the urethra (8.4 +/- 1.9 mm on vaginal vs. 11.5 +/- 2.2 mm on rectal scans, P < 0.01) and the transverse diameter of the urethra's smooth muscle complex (11.2 +/- 0.3 mm on vaginal vs. 8.6 +/- 0.2 mm on rectal scans, P < 0.001). No other variables showed significant differences. Compression of the urethra and displacement under the symphysis pubis were observed when the ultrasound probe was applied vaginally. Bland-Altman analysis showed acceptable variability for differences of distances but considerable variability for the differences of volumes. CONCLUSION: The female urethra can be examined both vaginally and rectally by three-dimensional ultrasound. A transvaginally applied probe seems to have a compression effect on the urethra.

Primary Bartholin gland carcinoma: a report of seven cases.

This study reviews our experience with 7 patients with primary Bartholin gland cancer (BGC) treated at the Queensland Gynaecological Cancer Centre (QCGC) and compares this with previously published data. A retrospective clinicopathologic review of all patients with primary BGC treated at QCGC from 1988 to 2000 was performed. Of the 7 patients treated, all underwent primary surgery and 5 of the 7 patients received radiotherapy postoperatively. All patients presented with a local swelling or a lump. Two had associated discharge and 2 had associated pain. Of the 7 patients, 2, 3 and 2 respectively were classified as having Stage IB, II or III disease. Five of the 7 patients had squamous cell carcinoma (SCC), one had adenoid-cystic carcinoma and 1 had a small-cell neuroendocrine cancer of the Bartholin gland. None of the patients with SCC developed recurrent disease. The patient with adenoid-cystic carcinoma experienced local recurrences at 4 years and again at 5 years and 3 months. Nine years after primary treatment she was diagnosed with pulmonary metastases. The patient with small-cell neuroendocrine cancer of the Bartholin gland was considered tumour-free after operation. Thorough imaging, including a CT scan of her chest, abdomen and pelvis showed no evidence of disease. She died 1 year and three months after diagnosis from disseminated pulmonary disease. We present the first report of small cell neuroendocrine cancer of the Bartholin gland. Therapeutic principles in the management of vulval cancer at other sites appear to be appropriate for management of BGC.
