Pelvic organ prolapse after hysterectomy: A 10-year national follow-up study.

INTRODUCTION: Hysterectomy may have an effect on the pelvic floor. Here, we evaluated the rates and risks for pelvic organ prolapse (POP) surgeries and visits among women with a history of hysterectomy for benign indication excluding POP. MATERIAL AND METHODS: In this retrospective cohort study 3582 women who underwent hysterectomy in 2006 were followed until the end of 2016. The cohort was linked to the Finnish Care Register to catch any prolapse-related diagnoses and operation codes following the hysterectomy. Different hysterectomy approaches were compared according to the risk for a prolapse, including abdominal, laparoscopic, laparoscopic-assisted vaginal and vaginal. The main outcomes were POP surgery and outpatient visit for POP, and Cox regression was used to identify risk factors (hazard ratios [HR]). RESULTS: During the follow-up, 58 women (1.6%) underwent a POP operation, of which a posterior repair was the most common (n = 39, 1.1%). Outpatient visits for POP symptoms occurred in 92 (2.6%) women of which posterior wall prolapses (n = 58, 1.6%) were the most common. History of laparoscopic-assisted vaginal hysterectomy were associated with risk for POP operation (HR 3.0, p = 0.02), vaginal vault prolapse operation (HR 4.3, p = 0.01) and POP visits (HR 2.2, p < 0.01) as compared to the approach of abdominal hysterectomy. History of vaginal deliveries and concomitant stress urinary continence operation were associated with the risk for a POP operation (HR 4.4 and 11.9) and POP visits (HR 3.9 and 7.2). CONCLUSIONS: Risk for POP operations and outpatient visits for POP symptoms in hysterectomized women without a preceding POP seems to be small at least 10 years after hysterectomy. History of LAVH, vaginal deliveries and concomitant stress urinary incontinence operations increased the risk for POP operations after hysterectomy. These data can be utilized in counseling women considering hysterectomy for benign indication.

Effect of hysterectomy on re-operation for stress urinary incontinence: 10 year follow-up.

PURPOSE: Hysterectomy and mid-urethral sling (MUS) are common operations, but little is known about how hysterectomy after MUS affects the risk for stress urinary incontinence (SUI) relapse. METHODS: We included 49 women with a MUS before hysterectomy and 41 women with a MUS concomitant with hysterectomy. The controls, matched by age (± 2 years), MUS type (retropubic vs transobturator) and operation year (± 2 years), included 201 women who underwent the MUS operation without a subsequent hysterectomy. We used health care registers for follow-up of 12.4 years in median (IQR 10.9-14.7) after the MUS operation to compare the number of SUI re-operations and hospital re-visits for urinary incontinence. RESULTS: The re-operation rates for SUI did not differ between the women with MUS before hysterectomy (n = 2, 4.1%), women with MUS concomitant with hysterectomy (n = 2, 4.9%) and their controls (n = 4, 4.9%, p = 0.8 and n = 6, 5.0%, p = 1.0, respectively). There were significantly fewer urinary incontinence re-visits among women who had a MUS concomitant with the hysterectomy compared to their matched controls (n = 2 and 31, 5 and 31%, p < 0.01) and to the women with a MUS prior to hysterectomy (n = 2 and 10, 5 and 20%, respectively, p = 0.03). CONCLUSION: Hysterectomy after or concomitant with MUS does not seem to increase the risk for SUI re-operation or hospital re-visits for urinary incontinence. These results can be used to counsel women considering hysterectomy after MUS operation or concomitant with MUS operation.

Paclitaxel, Carboplatin and 1,25-D3 Inhibit Proliferation of Ovarian Cancer Cells In Vitro.

BACKGROUND/AIM: The combination of paclitaxel and carboplatin is the standard chemotherapy for ovarian cancer. Previous studies have implied that vitamin D (1,25-D3) may have growth inhibitory effects in ovarian cancer. This study aimed to investigate the effect of paclitaxel, carboplatin and 1,25-D3 on the growth of ovarian cancer cells in vitro, based on the hypothesis that 1,25-D3 might potentiate the effect of paclitaxel and/or carboplatin. MATERIALS AND METHODS: Three non-commercial ovarian carcinoma cell lines UT-OV-1(mucinous), UT-OV-3B (serous) and UT-OV-4 (endometrioid) were exposed to different concentrations of 1,25-D3, paclitaxel and carboplatin, respectively. The cell viability was measured using a Crystal violet assay kit. The cellular vitamin D receptor (VDR) mRNA levels were measured by qRT-PCR using the LightCycler equipment. RESULTS: The growth-inhibitory effect of the combination of paclitaxel and carboplatin was 56% in UT-OV-1, 33% in UT-OV-3B and 47% in UT-OV-4 cells. Single 1,25-D3 (10 µM) inhibited the growth of UT-OV-3B and UT-OV-4 by 23% and 28%, respectively, whereas no effect was seen in UT-OV-1 cells. These results are in line with the finding that the expression of VDR was high in UT-OV-3B and UT-OV-4, but very low in UT-OV-1. The combination of 1,25-D3, paclitaxel and carboplatin resulted in 61%, 46% and 58% growth reduction in UT-OV-1, UT-OV-3B and UT-OV-4 cells, respectively. The additive effect of 1,25-D3 was 21% in UT-OV-4, 20% in UT-OV-3B and 12% in UT-OV-1 cell line. CONCLUSION: The results imply that combining 1,25-D3 with paclitaxel and carboplatin may potentiate their growth inhibitory effect on ovarian cancer cells with high VDR expression.

Paclitaxel, Carboplatin and 1,25-D3 Inhibit Proliferation of Endometrial Cancer Cells In Vitro.

BACKGROUND/AIM: Endometrial cancer cells are known to be sensitive to carboplatin and paclitaxel. Furthermore, vitamin D (1,25-D3) has been reported to inhibit endometrial cancer cell growth both as a single agent and combined with carboplatin. However, there are no studies comparing the effect of paclitaxel and carboplatin as single agents vs. in combination in endometrial cancer cell lines. Neither has the effect of 1,25-D3 been studied with paclitaxel. The present study investigated the effect of paclitaxel, carboplatin and 1,25-D3 on the growth of endometrial cancer cells in vitro. MATERIALS AND METHODS: Two endometrial adenocarcinoma cell lines (UT-EC-1 and UT-EC-3) were cultured with different doses of paclitaxel, carboplatin and 1,25-D3. The cellular VDR (vitamin D receptor) mRNA levels were measured and the expression of estrogen (ER) and progesterone (PR) receptors by the cells was determined. RESULTS: In the UT-EC-1 cell line the growth inhibition was 72% with paclitaxel, 54% with carboplatin and 73% with the combination of these compounds. The corresponding numbers in UT-EC-3 were 70%, 33% and 65%, respectively. 1,25-D3 suppressed cell growth 88% with paclitaxel, 63% with carboplatin and 87% with their combination in the UT-EC-1 cell line. CONCLUSION: In both cell lines, single-agent paclitaxel was as effective as the combination of the compounds and more effective than single carboplatin. 1,25-D3 may further contribute to the cytotoxic effect of these agents.
