Abstract
Backround and Aims: Soft-tissue reconstruction of the vulva following resection of malignancies is challenging. The function of perineal organs should be preserved and the reconstructed area should maintain an acceptable cosmetic appearance. Reconstruction with local flaps is usually sufficient in the primary phase after a radical vulvectomy. Numerous flaps have been designed for vulvar reconstruction usually based on circulation from the internal pudendal artery branches. In this paper we introduce our modification of the gluteal fold V–Y advancement flap as a primary reconstruction after a radical vulvectomy. Patients and Methods: Twenty-two patients were operated with a radical vulvectomy because of vulvar malignancies. The operation was primary in eight and secondary in 14 patients. The reconstruction of the vulva was performed in the same operation for each patient Results: All flaps survived completely. Wound complications were registered in three patients. Late problems with urinary stream were corrected in two patients. A local recurrence of the malignancy was observed in six patients during the follow-up period. Conclusions: Gluteal fold flap is easy to perform, has a low rate of complications and gives good functional results. Even a large defect can be reconstructed reliably with this method. A gluteal fold V–Y advancement flap is sensate and our modification allows the flap to be transposed with lesser dissection as presented before.

Abstract
Ovarian cancer is the most lethal gynaecological cancer. It appears that seemingly ovarian or primary peritoneal carcinomas, in fact, originate from fimbriae. BRCA1/2 mutation carriers are recommended for the removal of ovaries and fimbriae, to reduce the risk of cancer. Treatment of epithelial ovarian cancer is based on the combination of surgery and chemotherapy. The residual tumour volume at the primary operation is the most important predictive factor of survival. The best response at the primary treatment is observed with combination chemotherapy with taxane and platinum. Adding bevacitzumab to first line chemotherapy may improve survival.

Abstract
BACKGROUND Surgical treatment and staging of ovarian borderline tumors have been reported to be often suboptimal and differ considerably. We evaluated the extent of surgical treatment of these tumors in different hospital categories. MATERIAL AND METHODS A prospective survey performed in 1999 included 65 patients operated on for borderline ovarian tumors and covered 78% of such patients reported to the Finnish Cancer Registry. Detailed information of demographic data and surgical treatment was reported by the responsible physicians using a special questionnaire after confirmation of histopathology. RESULTS Fifty-eight patients (89%) had stage I tumor, only two patients (3%) had stage II disease and five patients (8%) had stage III disease with peritoneal implants. The majority of the patients underwent bilateral salpingo-oophorectomy (66%) and hysterectomy (58%). Unilateral salpingo-oophorectomy was performed for 21 (32%) and omentectomy for 22 (34%) patients. Ten out of the 16 women under 40 years of age had fertility-sparing surgery. Peritoneal biopsies were taken in 16 (25%) women and lymphadenectomy was performed for 9 (14%) patients with clinical suspicion of invasive ovarian carcinoma. Frozen section was taken in half of the patients and the histology remained the same in 72% of the final pathology reports. No clear differences of the extent of surgical treatment were detected between different hospital categories. Overall cumulative 5-year relative survival rate was 96%. CONCLUSIONS Bilateral salpingo-oophorectomy and hysterectomy was performed for the majority of patients with borderline ovarian tumor. More attention should be paid to adequate staging of borderline tumors in all hospital categories.

Abstract
Arterial bleeding, initially negative on MRI, ultrasonography and radiographic angiography, complicated the course of pregnancy with severe and recurrent vaginal and pelvic haemorrhage in the second trimester. Bleeding from the left uterine artery was successfully terminated by angiographic embolisation. No harmful effects on the fetal well-being were recorded after the embolisation. Massive haemorrhage, most probably from the right uterine artery, recurred some days later, and Caesarean section was performed. At postpartal ultrasonography and catheter angiography, massive arterial bleeding from a pseudoaneurysmatic vessel was clearly imaged on the right side of the cervical myometrium and could successfully be treated by radiographic embolisation. Though the primary aetiology of bleeding remains uncertain, it is possible that cervical endometriosis could have been associated with this complication.

Abstract
BACKGROUND There is growing interest to apply the sentinel node technique in the treatment of vulvar cancer. METHODS All charts of the patients operated on for vulvar cancer at Tampere University Hospital from January 1, 2001 through June 30, 2005 were retrospectively reviewed. Demographic, clinical, and histopathological information was collected from each patient. The sentinel lymph node mapping was done intraoperatively either with a combination of the radioisotope and dye techniques (40 patients) or with the dye technique alone (7 patients). The sentinel lymph node was dissected separately for histopathological evaluation, and then a routine inguinal lymphadenectomy was performed. RESULTS The final FIGO surgical Stage distribution was: Stage I, 11 (23%); Stage II, 14 (30%); Stage III, 21 (45%); and Stage IV, 1 (2%). Sentinel lymph node was identified in 46 (98%) women with either one or both of the methods. In Stage I-II, the sentinel lymph node identification rate was 25/25 (100%) with the combined method. The only patient with unidentified sentinel lymph node had lymphatic spread beyond inguinal area or Stage IV disease. Eighteen of the sentinel lymph nodes (39%) were positive for tumor cells, and in 5 cases additional metastatic nodes were found. One patient with macroscopically enlarged metastatic inguinal nodes and Stage III disease had a negative sentinel lymph node. In the 25 patients with Stage I-II disease, the false-negative rate of the sentinel lymph node method was 0/4, giving a negative predictive value of 1.00. CONCLUSIONS A sentinel node identification rate of 98% with a false-negative rate of 0% in the patients with Stage I-II disease is an encouraging finding.

A randomised phase III study comparing high-dose chemotherapy to conventionally dosed chemotherapy for stage III ovarian cancer: the Finnish Ovarian Cancer (FINOVA) study. Eur J Cancer 2006; 42:2196-9.

Abstract
Women with stage III ovarian cancer and with < or = 2 cm residual tumour were randomly assigned to receive either conventionally dosed chemotherapy (group A) or HDCT (group B). Patients allocated to group A received 6 cycles of paclitaxel (T) 135 mg/m2 and cisplatin (P) 75 mg/m2 every 3 weeks, and those allocated to HDCT received 3 TP cycles followed by peripheral blood stem cell mobilisation with cyclophosphamide (C) 3000 mg/m2 and T 175 mg/m2, and subsequently HDCT with carboplatin 1500 mg/m2, C 120 mg/kg, and mitoxantrone 75 mg/m2. The trial was closed early after 42 patients were entered due to slow accrual. The median follow-up time of patients who were alive was 81 months. The median progression-free survival time was 15.9 and 16.6 months (hazard ratio, HR 0.83; 95% CI 0.41-1.69, P = 0.61) and the median overall survival time was 43.7 and 64.3 months (HR, 0.74; 95% CI 0.34-1.61, P = 0.44) in groups A and B, respectively. Although one patient died of HDCT-related toxicity, the regimen was otherwise relatively well tolerated. We conclude that the HDCT regimen used was feasible, but did not result in significantly improved survival in this prematurely closed trial. A clinically important survival benefit cannot be excluded due to the small sample size.

Abstract
This prospective nation-wide study was performed to evaluate the effect of hospital category and subspeciality training on surgical treatment of ovarian cancer. Data were obtained from a questionnaire filled in by the operating unit, and from the surgical and histopathology reports. The survey included 307 patients. Half of them were operated in the university hospitals where gynaecologic oncologists performed 72% of the operations. This was the case in only 4% and 19% in the central and district hospitals, respectively. In university hospitals, pelvic lymphadenectomy was performed in 88%, and para-aortic lymphadenectomy in 73%, of the patients with stage I disease. The corresponding figures ranged from 11% to 21% in central and district hospitals. For stage III patients operated by gynaecologic oncologists, the estimated odds ratio for no macroscopic tumour was 3.0 times higher (95% CI 1.2-7.5) than for those operated by general gynaecologists. These results favour centralisation of surgical treatment of ovarian cancer.

Abstract
INTRODUCTION The purpose of this study was to evaluate the feasibility, clinical outcome and complications of laparoscopic surgery in women with endometrial cancer and to compare surgical outcome and postoperative early and late complications with results of traditional laparotomy. METHODS Forty women with endometrial cancer underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Each patient operated by laparoscopy was matched by age, preoperative clinical stage and histology of the endometrial cancer with a patient treated by the same operation but using traditional laparotomy. Half of these patients underwent total pelvic lymphadenectomy and half had pelvic lymph node sampling. The groups were compared in clinical characteristics, surgical outcomes, recoveries and early and late postoperative complications. RESULTS The patients in the laparoscopy group had less blood loss, more lymph nodes removed, shorter hospital stay but longer operation time than those treated by laparotomy. Only one (2.5%) laparoscopy was converted to laparotomy due to pelvic adhesions. There were no intraoperative complications in either group. Postoperative complications were more common (55.0%) in the laparotomy than in the laparoscopy group (37.5%). Only one major complication (2.5%) occurred among patients undergoing laparoscopy as compared with three (7.5%) major complications in the laparotomy group. Superficial wound infection was the most common (20%) infection in laparotomy patients while vaginal cuff cellulitis occurred in 10% of laparoscopy patients. Late (>42 days) postoperative complications were almost equally frequent (20.0 and 22.5%) in both groups. Lower extremity lymph edema or pelvic lymph cyst was found in 12.5% of all cases. As a result of surgical staging the disease of 6 women (15%) in both groups was upgraded. CONCLUSIONS Laparoscopic surgery is a viable alternative to traditional surgery in the management of endometrial cancer. The surgical outcome is similar in both cases. In laparoscopic procedures the operation time is longer but the postoperative recovery time shorter than in laparotomy. Severe complications were limited in both groups, while wound infections can be avoided using laparoscopy.

Abstract
The application of a new segmentation software, Anatomatic in the evaluation of volumetric measurements of ovarian tumours and the new Medimag three-dimensional (3D) software in the evaluation of 3D image representation of ovarian tumours with 1.5 T magnetic resonance imaging (MRI) is described. Our goal was to compare MRI based volumetry with operative findings at laparotomy for six consecutive patients with suspected ovarian tumours. Volumetric analysis and three dimensional image reconstructions of the tumours were obtained. At laparotomy, the tumour sizes were measured in situ, and the volumes were calculated. Using Anatomatic, reproducible tumour volumes were achieved with ease and within a reasonably fast time in patients with ovarian tumours without ascites. Medimag helped achieve realistic 3D representations of the tumours. For the four solitary tumours segmentation based volumetry and laparotomy findings agreed in three cases. In one patient with an oval shaped tumour, the segmented volume was double as compared to that estimated at laparotomy. Of the two patients with multiple tumours, both patients had significant ascites, and volumetry misinterpreted the fluid as tumour cyst fluid and markedly overestimated the tumour size. In conclusion, the MRI based segmentation volumetry and 3D image reconstructions are rapid, and reproducible methods of measuring ovarian tumours in patients without significant ascites.

Abstract
BACKGROUND Cytokines play a key role in the regulation of cells of the immune system and also have been implicated in the pathogenesis of malignant diseases. Some cytokines have been shown to have potential in the diagnosis of cancer. METHODS A total of 111 patients with ovarian, cervical, or endometrial carcinomas or benign ovarian or uterine tumors were enrolled on the study, and the levels of interleukin (IL)-2, IL-4, IL-6, IL-10, interferon (IFN)-gamma, granulocyte-colony stimulating factor (G-CSF), granulocyte-macrophage-colony stimulating factor (GM-CSF), macrophage-colony stimulating factor (M-CSF), and tumor necrosis factor (TNF)-alpha were measured by cytokine specific, enzyme-linked immunoadsorbent assays. In addition, ratios of IL-2, IL-4, and IFN-gamma production were studied to characterize the type of T-cell response that occurred in the peritoneal cavities of the patients. RESULTS High levels of M-CSF (mean for all patients, 26,050 pg/mL) and G-CSF (mean for all patients, 20,267 pg/mL) were observed in virtually all patients, but no significant differences between the study groups were observed. Similarly, no differences in the levels of IL-2, IL-4, IL-10, IFN-gamma, GM-CSF, or TNF-alpha were found. However, IL-6 levels were significantly higher in patients with ovarian carcinoma (mean +/- standard error of the mean [SEM]: 5572 +/- 1266) or benign tumors (mean +/- SEM: 4474 +/- 2008) than in those with cervical (mean +/- SEM: 1222 +/- 546) or endometrial carcinoma (mean +/- SEM: 1977 +/- 616). A predominantly Th1 type cytokine profile, irrespective of the diagnosis, was observed in patients with gynecologic tumors. CONCLUSIONS With the exception of IL-6, the cytokine synthesis profiles in the peritoneal fluids of patients with benign and malignant gynecologic tumors were found to be similar. These results suggest that cytokine production in these patients is a result of nonspecific inflammation rather than a specific response against the tumor cells, and that skewing of cytokine synthesis toward either the Th1 or the Th2 phenotype is not the underlying mechanism resulting in the malignant process in women with gynecologic tumors.

Abstract
Activation of T helper cells is a prerequisite for the function of cytotoxic T lymphocytes (CTL) and the maturation of the B cell response. Because epitopes recognized by each of these cells may overlap, we scanned the E2 protein of human papillomavirus (HPV) type 16 to identify the T helper cell epitopes. Four major T helper cell epitopes (mapping between aa:s 11-25, 141-155, 191-205 & 231-245) and adjacent human B cell epitopes were found. The first peptide-defined epitope (RLNV) 11CQDKILTHYENDSTD25 overlapped five putative HLA-I (A1, A2, A0205, A3 & A11) binding motifs (CQDKILTHY, RLNVCQDKI, NVCQDKIL, RLNVCQDK & RLNVCQDK). This epitope is also part of an N-terminal alpha-helix which may form four HLA-II (DR2, DR4, DR7 & DR8) specific agretopes for structures recognizable by the T cell receptor (e.g. KILT). The second epitope 141EEASVTVVEGOVDYY155 (GLYY) overlapped the putative HLA-A1 & HLA-Bw37 binding motifs (VVEGQVDYY/QVDYYGLYY and EEASVTVV), and two HLA-II (DR1 & DR3) specific agretopes. The third and fourth epitopes were not associated with more than one putative CTL epitope each. Only the first epitope shared considerable aa-homology with corresponding regions of other genital HPV types.

Abstract
Estrogen and progesterone receptor contents (ER, PR) were assessed by an immunohistochemical method and DNA ploidy and S-phase by flow cytometry in frozen endometrial cancer tissue sections from 39 cases. Comparison of the immunohistochemical and cytosol assays showed 81% and 84% concordance in ER and PR contents, respectively. An aneuploid DNA pattern was identified in 30% and a high S-phase fraction was found in 33% of 36 specimens studied. Negative ER status was associated with aneuploid and high S-phase fraction. A similar association was found between PR status and high S-phase fraction. Combined analysis of immunohistochemical receptor status and DNA flow cytometry in the same sample makes it possible to identify two strong predictive factors in endometrial adenocarcinoma.

Abstract
We determined DNA content, S-phase fraction, and estrogen (ER) und progesterone receptor (PR) levels in 36 stage I endometrial adenocarcinomas and in 22 hyperplastic lesions to obtain information on the genesis and progression of endometrial malignancy. DNA aneuploidy was detected in 12/36 (33%) carcinomas and in none of the hyperplastic lesions. DNA aneuploidy was significantly more common in poorly and moderately differentiated carcinomas than in the well-differentiated ones. Similarly, the highest number of cells in S-phase were found in poorly and moderately differentiated carcinomas, whereas well-differentiated carcinomas and all hyperplasias had an equally small S-phase fraction. Mean ER and PR levels were highest in hyperplastic lesions, especially those with atypical features, whereas carcinomas of all grades had significantly lower values. Thus, it is likely that the loss or decreased expression of steroid receptors is an early event during carcinogenesis in human endometrium, whereas an increase in the cell proliferation rate and the formation of DNA aneuploidy occur later during tumor progression.

Abstract
Antioxidant enzyme activities and lipid peroxidation were analysed in normal endometrium and endometrial cancer tissues from Finnish and Japanese patients. The catalase and glutathione peroxidase activities of normal endometrium were significantly lower in Finns than in Japanese. Lipid peroxidation was slightly higher in endometrial cancer as compared with normal endometrium both in the Finns and in the Japanese. When cancer tissues were compared with normal endometrium both in Finns and Japanese the activity of superoxide dismutase was significantly lower in cancer tissue than in normal endometrium. In Finns glutathione S-transferase activity was also lower in endometrial cancer tissue than in normal endometrium, and a similar tendency was also found in Japanese. This study suggests that endometrial cancer tissue is associated with an impaired enzymic antioxidant defence system.

Abstract
Serum antibodies to early proteins of human papillomavirus type 16 (HPV 16 E2 protein) and herpes simplex virus type 2 (HSV 2 ICP8) can be measured by ELISA. In the serum of 122 newly diagnosed cervical carcinoma patients and age-matched controls, enhanced IgA antibody levels to an HPV-16 E2 protein derived peptide no. 245 indicated a 9.5-fold (95% confidence limits 2.8-57.2) relative risk of cervical carcinoma. No significant risk was found with a corresponding HPV 6 E2 peptide or HSV 2 ICP8. To evaluate the HPV 16 E2 peptide as a possible tumor marker for cervical carcinoma serial postoperative serum samples were tested from 27 women with cervical carcinoma. Antibody responses to the HPV 16 E2 peptide depended on the clinical stage. Stage I and II patients showed decreasing posttreatment IgA and/or IgG antipeptide antibody levels. Stage III and IV patients initially showed decreasing antipeptide antibody levels followed by increasing levels. These patients also showed increasing IgG antibody levels to the HSV 2 ICP8. However, increasing antibody levels to the HPV 16 E2 peptide indicated significantly (P less than 0.05) worse 2-year disease free survival (recurring disease) than did stable or decreasing antibody levels. The results suggest that serum antipeptide antibodies to the HPV 16 E2 peptide no. 245 can be used for the monitoring of cervical carcinoma.

Abstract
To assess the role of interleukin-1 beta (IL-1 beta) and tumour necrosis factor alpha (TNF alpha) in the physiological host defence mechanisms against malignancies, the production of these cytokines in sera, ascitic and cyst fluids and in the tumour tissues of patients with benign or malignant ovarian tumours was studied. IL-1 beta was found neither in the sera nor in the ascitic fluids of these patients. It was also virtually absent from the cyst fluid samples. However, a mean value of 790 pg IL-1 beta/g tumour was found. Like IL-1 beta, TNF alpha was virtually absent in the serum samples. It was, however, detectable in the ascitic and cyst fluids and tumour tissues. The TNF alpha concentrations were highest in the tumour tissues, with a mean level of 328 pg/g tumour. When comparing the level of IL-1 beta and TNF alpha in patients with benign tumours to that seen in patients with malignant tumours, no differences in production were observed, regardless of the origin of the test samples. Our results indicate the production of IL-1 beta and TNF alpha in patients with ovarian tumours. More importantly, the finding that the production of these cytokines in patients with benign tumours is similar to that in patients with malignant tumours supports the conclusion that the production of these cytokines is more a nonspecific indicator of an inflammatory process than a specific response to a malignant process.

This prospective double-blind, multicenter study was aimed at evaluating the clinical efficacy of RA 233 (a derivative of dipyridamole) in ovarian cancer. Following primary surgery, 497 patients with ovarian cancer were treated with combination cytotoxic chemotherapy; those in clinical stage II were also treated with pelvic irradiation. The patients were randomly allocated to receive RA 233 (N = 251) or placebo (N = 246) for 2 years. The groups did not significantly differ from each other in any of the clinical, therapeutic, or histopathological variables evaluated. There were no significant differences between RA 233-treated patients and placebo-treated patients with respect to appearance of new metastases, progressive growth of malignancy, or survival of all patients, in any of the clinical stages of the disease, in radically operated patients or in nonradically operated patients, in different histopathological groups, or in different age groups. Hence, supplementation of carcinoma therapy with long-term administration of the antiplatelet drug RA 233 has no clinical benefit in this malignancy. Using Cox's multifactorial stepwise analysis, this study revealed that the clinical stage of the disease, the extent of surgery, and the histopathology of the tumor, but not the age of the patient or the use of RA 233, were significant and independent predictors of survival. With respect to the histopathology, the poor prognosis of serous and mesonephric carcinomas appeared to be independent of the other prognosis indicators.

Abstract
Vitamin D metabolites and minerals involved in bone metabolism were studied in 68 control mothers, 14 gestational diabetics and 68 insulin-dependent diabetics during pregnancy and at delivery. 25(OH)D and 1,25(OH)2D concentrations were significantly (p less than 0.001) lower in insulin-dependent diabetics than in the control or gestational diabetic groups. A similar difference was also observed between infants. 24,25(OH)2D, phosphorus and magnesium values were similar in all groups. Corrected calcium values were significantly lower in both mothers (p less than 0.001) and infants (p less than 0.05) in the insulin-dependent group than in the other two groups. Postpartum, 10% of infants of diabetic mothers received calcium therapy. Our results show alterations in vitamin D and mineral metabolism in pregnant insulin-dependent diabetics and their newborn infants and indicate observation during pregnancy and after delivery.

Abstract
Serum concentrations of vitamin A (retinol), vitamin E (alpha-tocopherol) and total carotene were measured in 88 women with gynecologic cancer (9 vulvar, 15 cervical, 36 endometrial and 28 ovarian carcinomas) and 31 healthy controls. No significant differences were found in the serum levels of the vitamins and carotene in patients with vulvar, cervical or endometrial cancer compared to the controls. The patients with ovarian cancer had a significantly (P less than 0.01) lower mean serum level of vitamin A than the controls, while carotene and vitamin E level were similar in both groups. The results indicate that vitamin A may have a role in the metabolism of patients with advanced ovarian cancer.

Abstract
Between 1962 and 1983 a total of 26 patients with malignant trophoblastic disease were diagnosed in northern Finland. The incidence of this disease was 1:21,000 pregnancies. Eight patients had choriocarcinoma and 18 an invasive mole. Clinically, 15 patients belonged to the nonmetastatic and 11 to the metastatic group. Of the latter, 4 patients belonged to the Iow-and 7 to the high-risk categories. During the first years of the study period, cytotoxic chemotherapy, mostly single-drug therapy, was often complemented with adjunctive surgery and/or irradiation. During recent years, single- or multidrug chemotherapy was supplemented with surgery in only one case with chemotherapy-resistant pulmonary metastases. All 26 patients are alive and disease-free, and after therapy 6 of them have given birth to 1-3 children. Our results suggest that malignant trophoblastic diseases can be successfully treated also in small centers of gynecologic oncology with up-to-date knowledge of the principles of modern cytotoxic chemotherapy.

Abstract
Serum concentrations of 25(OH)D, 24,25(OH)2D, 1,25(OH)2D, total protein, calcium, phosphorus, magnesium and alkaline phosphatase were measured in patients with intrahepatic cholestasis of pregnancy and in control subjects at the third trimester of pregnancy and at delivery. 25(OH)D levels of 40.5 +/- 21.5 nmol/l in the patient group were initially significantly (P less than 0.01) higher than the value of 26.3 +/- 9.5 nmol/l in the control group and decreased significantly (P less than 0.01) to 26.0 +/- 16.3 nmol/l at delivery. The levels of active 1,25(OH)2D and inactive 24,25(OH)2D did not alter in either group. Also the concentrations of calcium, phosphorus and magnesium remained unchanged in both groups. No significant differences in fetal vitamin D metabolites were observed between patients and controls, and the other analysed fetal parameters were similar in both groups. Cholestyramine and/or phenobarbital treatment had no influence on vitamin D metabolites. Since levels of 1,25(OH)2D and mineral parameters remained normal and a change in 25(OH)D concentrations was only transient, the clinical role of 25(OH)D variations cannot be substantial.

Abstract
Serum concentrations of 25(OH)D, 24,25(OH)2D, 1,25(OH)2D, total calcium, protein, phosphorus, magnesium and alkaline phosphatase were measured in two groups of Finnish women throughout pregnancy and in cord serum at delivery. The autumn group delivered in August-September and the spring group in February-March. There was strong seasonal variation in the 25(OH)D concentrations in both groups. Maternal values (mean +/- s.d.) at delivery were 44.3 +/- 20.8 nmol/l in autumn and 26.0 +/- 13.0 nmol/l in spring. Fetal concentrations were 28.8 +/- 14.3 and 18.3 +/- 11.3 nmol/l, respectively. In both mothers and infants low 25(OH)D values were measured in winter. In the autumn group 7 out of 21 mothers (33 per cent) and in the spring group 17 out of 36 mothers (47 per cent) had values below 17 nmol/l, which is the lowest winter reference value recorded in our laboratory. No significant seasonal variation was observed in dihydroxylated vitamin D metabolites, although 24,25(OH)2D values were a little higher in summer than in winter. Concentrations of 1,25(OH)2D tended to rise towards delivery. Corrected calcium, magnesium and phosphorus concentrations did not change during pregnancy. Fetal calcium and phosphorus concentrations were significantly (P less than 0.001) higher than maternal ones. The data indicate that many mothers and infants have poor vitamin D status in the latitude of Finland. Our results support the concept that vitamin D supplementation should be considered in Finland for pregnant women at least in winter.

Tumor-associated antigen Ca 125 before and during the treatment of ovarian carcinoma. Obstet Gynecol 1986; 67:468-72.

Abstract
Serum concentrations of Ca 125, a tumor-associated antigen of epithelial ovarian cancer, were measured in 29 ovarian cancer patients before cytoreductive surgery and in 112 patients during and after treatment. Ca 125 levels were increased (greater than 30 IU/mL) in 89.8% of patients with clinically demonstrable ovarian tumors and were negative in 92.1% of clinically disease-free patients. Low levels of Ca 125 were associated with early clinical stages or a minimal tumor burden, and predicted a successful response to treatment and a low recurrence rate. High values indicated advanced disease and a poor response to cytotoxic chemotherapy. In 77% of patients the operation was explorative, with a preoperative Ca 125 level higher than 1000 IU/mL, whereas all the patients with values less than 100 IU/mL could be operated radically. Serum levels of Ca 125 were increased in similar frequency in epithelial, sex cord, and germ cell ovarian malignancies. The assay of Ca 125 seems to be a reliable noninvasive method for monitoring the presence and clinical behavior of ovarian cancer. Preoperative values have prognostic significance in predicting operability and response to chemotherapy.

Abstract
Seventy-seven women had 98 pregnancies after a cone biopsy of the cervix. There were 62 deliveries, 26 legal abortions, 9 spontaneous abortions and 1 ectopic pregnancy. Cervical cerclage was done for 22 out of 62 conized parturients (35.4%) and for none in the matched control group. There were 4 (6.4%) preterm deliveries in the cone biopsy group and 1 in the control group. The perinatal mortalities were 3.2% and 0% respectively. The mean duration of labour was 2.4 h shorter in the conized parturients than in the controls (P less than 0.05) but there were no difference in the mode of delivery in the two groups.

Abstract
The concentration of 25-hydroxyvitamin D (25(OH)D) was measured in 85 samples of amniotic fluid (AF) obtained near term from mothers with normal pregnancy, diabetes, pre-eclampsia or intrahepatic cholestasis of pregnancy. Significantly lower AF 25(OH)D levels were found in diabetic mothers than in the three other groups. Our results suggest that the vitamin D status of the fetoplacental unit may be somewhat impaired in diabetic pregnancy.

Abstract
To investigate the role of the fetus in vitamin D metabolism concentrations of vitamin D metabolites, 25(OH)D, 24,25(OH)2D and 1,25(OH)2D, were measured in human umbilical artery and vein. There were no differences between artery and vein in 25(OH)D and 24,25(OH)2D levels. 1,25(OH)2D concentrations were statistically significantly higher in the artery than in the vein. It has been shown in animal experiments that 1,25(OH)2D is an important factor in the maintenance of the placental calcium gradient. We suggest that the fetus actively produces 1,25(OH)2D and hence has the capacity to control its calcium influx.
