Postoperative Urinary Incontinence in Diabetic Patients Undergoing Pelvic Reconstructive Surgery.

IMPORTANCE: Diabetes is an independent risk factor for urinary incontinence, and its impact on rates of postoperative incontinence after pelvic reconstructive surgery remains unexplored. OBJECTIVE: The aim of the study was to compare the incidence of postoperative stress urinary incontinence (SUI), urgency urinary incontinence (UUI), and mixed urinary incontinence in patients with diabetes mellitus undergoing surgery for pelvic organ prolapse (POP) with or without SUI surgery. STUDY DESIGN: This is a secondary analysis of a multicenter retrospective cohort study involving 10 diverse medical centers that identified a cohort of women with diabetes who had prolapse and/or anti-incontinence surgery. We compared rates of postoperative urinary incontinence among patients who had surgery for prolapse and incontinence versus surgery for prolapse only. RESULTS: Three hundred five patients had surgery for prolapse and incontinence, 330 had surgery for prolapse only, and 189 had anti-incontinence surgery only. De novo UUI was higher among those who underwent surgery for POP and SUI compared with surgery for POP alone (26.4% vs 14.1%, P < 0.01). Rates of persistent SUI (21% vs 4.9%, P < 0.01) and mixed urinary incontinence (15.9% vs 2.7%, P < 0.01) were higher for those who underwent prolapse surgery alone versus prolapse and an incontinence procedure. No differences were seen in hemoglobin A1C levels between those who did and did not report postoperative UI. CONCLUSIONS: We found that postoperative de novo UUI rates were high among patients with diabetes after pelvic reconstructive surgery, with the incidence being significantly higher for those who had surgery for prolapse and incontinence compared with surgery for prolapse only.

Surgical Outcomes in Urogynecology-Assessment of Perioperative and Postoperative Complications Relative to Preoperative Hemoglobin A1c-A Fellows Pelvic Research Network Study.

OBJECTIVES: Poor control of diabetes mellitus is a known predictor of perioperative and postoperative complications. No literature to date has established a hemoglobin A1c (HbA1c) cutoff for risk stratification in the urogynecology population. We sought to identify an HbA1c threshold predictive of increased risk for perioperative and postoperative complications after pelvic reconstructive surgery. METHODS: This multicenter retrospective cohort study involving 10 geographically diverse U.S. female pelvic medicine and reconstructive surgery programs identified women with diabetes who underwent prolapse and/or stress urinary incontinence surgery from September 1, 2013, to August 31, 2018. We collected information on demographics, preoperative HbA1c levels, surgery type, complications, and outcomes. Sensitivity analyses identified thresholds of complications stratified by HbA1c. Multivariate logistic regression further evaluated the association between HbA1c and complications after adjustments. RESULTS: Eight hundred seven charts were identified. In this diabetic cohort, the rate of overall complications was 44.1%, and severe complications were 14.9%. Patients with an am HbA1c value of 8% or greater (reference HbA1c, <8%) had an increased rate of both severe (27.1% vs 12.8%, P < 0.001) and overall complications (57.6% vs 41.8%, P = 0.002) that persisted after multivariate logistic regression (odds ratio, 2.618; 95% confidence interval, 1.560-4.393 and odds ratio, 1.931; 95% confidence interval, 1.264-2.949, respectively). Mesh complications occurred in 4.6% of sacrocolpopexies and 1.7% of slings. The average HbA1c in those with mesh exposures was 7.5%. CONCLUSIONS: Preoperative HbA1c of 8% or higher was associated with a 2- to 3-fold increased risk of overall and severe complications in diabetic patients undergoing pelvic reconstructive surgery that persisted after adjustments.

Molecular-integrated risk profile to determine adjuvant radiotherapy in endometrial cancer: Evaluation of the pilot phase of the PORTEC-4a trial.

OBJECTIVE: The Post-Operative Radiation Therapy in Endometrial Carcinoma (PORTEC)-4a trial is a randomized trial for women with high-intermediate risk endometrial cancer (EC), comparing individualized adjuvant treatment based on a molecular-integrated risk profile to standard adjuvant treatment; vaginal brachytherapy. To evaluate patient acceptability and pathology logistics of determining the risk profile, a pilot phase was included in the study. METHODS: PORTEC-4a is ongoing and the first 50 patients enrolled were included in the pilot phase. Primary endpoints of the pilot phase were patient acceptance, evaluated by analyzing the screening logs of the participating centers, and logistical feasibility of determination of the risk profile within 2 weeks, evaluated by analyzing the pathology database. RESULTS: In the first year, 145 eligible women were informed about the trial at 13 centers, of whom 50 (35%) provided informed consent. Patient accrual ranged from 0 to 57% per center. Most common reasons for not participating were: not willing to participate in any trial (43.2%) and not willing to risk receiving no adjuvant treatment (32.6%). Analysis of the pathology database showed an average time between randomization and determination of the molecular-integrated risk profile of 10.2 days (1-23 days). In 5 of the 32 patients (15.6%), pathology review took >2 weeks. CONCLUSIONS: The PORTEC-4a trial design was proven feasible with a satisfactory patient acceptance rate and an optimized workflow of the determination of the molecular-integrated risk profile. PORTEC-4a is the first randomized trial to investigate use of a molecular-integrated risk profile to determine adjuvant treatment in EC.

Routine pelvic lymphadenectomy in apparently early stage endometrial cancer.

AIMS: Controversial issues with respect to the treatment of patients with endometrial cancer include indications for lymphadenectomy and adjuvant radiotherapy. PATIENT AND METHODS: Between 1998 and 2004 all women with endometrial cancer stage I were included (n = 335). They all underwent total abdominal hysterectomy and bilateral salpingo-oöphorectomy. Two hundred and thirty-seven women also had a pelvic lymphadenectomy. When pelvic lymphadenectomy was performed, radiotherapy was administered only to patients with lymph-node metastases. Otherwise, adjuvant radiotherapy was based on the presence of risk factors. RESULTS: Eleven patients had lymph-node metastases. The overall absolute and relative survival-estimate at 5 years was 85.0 and 93.7%, respectively. Loco-regional recurrence was 8.5%. In the group with pelvic lymphadenectomy and negative lymph nodes these rates were 88.2, 93.9 and 5.6%, respectively. In 58 patients without any of the risk factors tumour grade III, deep myometrial invasion, or age > or =60 years, no lymph-node metastases were found. CONCLUSION: In patients with endometrial cancer FIGO stage I without risk-factors, a phenomenon which occurs in about 25% of patients with clinical stage I endometrial cancer, a lymphadenectomy can be omitted. In other patients, the debate regarding the optimal treatment will remain.

Re-irradiation and hyperthermia for recurrent breast cancer in the orbital region: a case report.

Based on the good results of re-irradiation plus hyperthermia in breast cancer recurrences on the chest wall, it was decided to offer similar treatment to a patient with recurrent metastatic breast cancer in the orbital region. A female patient was diagnosed in 1997 with breast cancer stage T4N0M0. She was treated with six neo-adjuvant chemotherapy courses and mastectomy, followed by hormonal treatment. In December 1998, she was diagnosed with metastatic disease in the medial upper quadrant of the left orbit. This was excised, followed by 40 Gy radiotherapy. Nine months later, the tumour had recurred in the left orbit at the margin of the radiotherapy field. This again was treated with surgery, followed by 30 Gy radiotherapy. Two months thereafter, the eyelid tumour progressed and hormonal therapy was changed, without an effect on the eyelid tumour. Screening gave no evidence of tumour activity elsewhere. The patient preferred treatment with re-irradiation plus hyperthermia to a surgical approach. Eight fractions of 4 Gy were given in 4 weeks, combined with once weekly hyperthermia. One week after treatment, the tumour had regressed completely. The patient died 22 months following treatment. Until last follow-up, a few weeks before death, the patient mentioned a dry left eye for which she used eyedrops, an unchanged vision and no further difficulties. On examination, there was epilation of the eyelids, a slight conjunctival oedema, no subcutaneous fibrosis and no evidence of tumour regrowth. For this patient, a surgical approach would have resulted in loss of the left eye. Toxicity of re-irradiation plus hyperthermia might lead to either a loss of vision or a delayed loss of her left eye due to treatment-induced toxicity. The chosen local treatment resulted in a very good palliative effect, which lasted for the patient's remaining lifetime of 22 months.

The morbidity of treatment for patients with Stage I endometrial cancer: results from a randomized trial.

PURPOSE: To compare the treatment complications for patients with Stage I endometrial cancer treated with surgery and pelvic radiotherapy (RT) or surgery alone in a multicenter randomized trial. METHODS AND MATERIALS: The Postoperative Radiation Therapy in Endometrial Carcinoma (PORTEC) trial included patients with endometrial cancer confined to the uterine corpus, either Grade 1 or 2 with more than 50% myometrial invasion, or Grade 2 or 3 with less than 50% myometrial invasion. Surgery consisted of an abdominal hysterectomy and oophorectomy, without lymphadenectomy. After surgery, patients were randomized to receive pelvic RT (46 Gy), or no further treatment. A total of 715 patients were randomized. Treatment complications were graded using the French-Italian glossary. RESULTS: The analysis was done at a median follow-up duration of 60 months. 691 patients were evaluable. Five-year actuarial rates of late complications (Grades 1-4) were 26% in the RT group and 4% in the control group (p < 0.0001). Most were Grade 1 complications, with 5-year rates of 17% in the RT group and 4% in the control group. All severe (Grade 3-4) complications were observed in the RT group (3%). Most complications were of the gastrointestinal tract. The symptoms resolved after some years in 50% of the patients. Grade 1-2 genitourinary complications occurred in 8% of the RT patients, and 4% of the controls. Bone complications occurred in 4 RT patients (1%). Seven patients (2%) discontinued their RT due to acute RT-related symptoms. Patients with acute morbidity had an increased risk of late RT complications (p = 0.001). The 4-field box technique was associated with a lower risk of late complications (p = 0.06). CONCLUSION: Pelvic RT increases the morbidity of treatment in Stage I endometrial cancer. In the PORTEC trial, severe complications occurred in 3% of treated patients, and over 20% experienced mild (mostly Grade 1) symptoms. Patients with acute RT-related morbidity had an increased risk of late complications. As pelvic RT in Stage I endometrial carcinoma was shown to significantly reduce the rate of locoregional recurrence, but without a survival benefit, its use in the adjuvant setting requires careful patient selection (treating those at increased risk of relapse), and the use of treatment schemes with the lowest risk of morbidity.

The potential impact of treatment variations on the results of radiotherapy of the internal mammary lymph node chain: a quality-assurance report on the dummy run of EORTC Phase III randomized trial 22922/10925 in Stage I--III breast cancer(1).

PURPOSE: To present the results of the dummy run of the European Organization for Research and Treatment of Cancer (EORTC) trial investigating the role of adjuvant internal mammary and medial supraclavicular (IM-MS) irradiation in Stage I--III breast cancer. METHODS AND MATERIALS: All participating institutions were asked to produce a treatment plan without (Arm 1) and with (Arm 2) simultaneous IM-MS irradiation of 1 patient after mastectomy and of 1 patient after lumpectomy. Thirty-two dummy runs have been evaluated for compliance to protocol guidelines, with respect to treatment technique and dose prescription. RESULTS: A number of more or less important deviations in treatment setup and prescription have been found. The dose in the IM-MS region deviated significantly from the prescribed dose in 10% of the cases for Arm 1, and in 21% for Arm 2. Assuming a true 5% 10-year survival benefit from optimal IM-MS irradiation, an increase of only 3.8% will be found due to this suboptimal dose distribution. CONCLUSION: In the dummy run, a number of potential systematic protocol deviations that might lead to false-negative results were detected. By providing recommendations to the participating institutions, we expect to improve the interinstitutional consistency and to promote a high quality irradiation in all institutions participating in the trial.

Surgery and postoperative radiotherapy versus surgery alone for patients with stage-1 endometrial carcinoma: multicentre randomised trial. PORTEC Study Group. Post Operative Radiation Therapy in Endometrial Carcinoma.

BACKGROUND: Postoperative radiotherapy for International Federation of Gynaecology and Obstetrics (FIGO) stage-1 endometrial carcinoma is a subject of controversy due to the low relapse rate and the lack of data from randomised trials. We did a multicentre prospective randomised trial to find whether postoperative pelvic radiotherapy improves locoregional control and survival for patients with stage-1 endometrial carcinoma. METHODS: Patients with stage-1 endometrial carcinoma (grade 1 with deep [> or =50%] myometrial invasion, grade 2 with any invasion, or grade 3 with superficial [<50%] invasion) were enrolled. After total abdominal hysterectomy and bilateral salpingo-oophorectomy, without lymphadenectomy, 715 patients from 19 radiation oncology centres were randomised to pelvic radiotherapy (46 Gy) or no further treatment. The primary study endpoints were locoregional recurrence and death, with treatment-related morbidity and survival after relapse as secondary endpoints. FINDINGS: Analysis was done according to the intention-to-treat principle. Of the 715 patients, 714 could be evaluated. The median duration of follow-up was 52 months. 5-year actuarial locoregional recurrence rates were 4% in the radiotherapy group and 14% in the control group (p<0.001). Actuarial 5-year overall survival rates were similar in the two groups: 81% (radiotherapy) and 85% (controls), p=0.31. Endometrial-cancer-related death rates were 9% in the radiotherapy group and 6% in the control group (p=0.37). Treatment-related complications occurred in 25% of radiotherapy patients, and in 6% of the controls (p<0.0001). Two-thirds of the complications were grade 1. Grade 3-4 complications were seen in eight patients, of which seven were in the radiotherapy group (2%). 2-year survival after vaginal recurrence was 79%, in contrast to 21% after pelvic recurrence or distant metastases. Survival after relapse was significantly (p=0.02) better for patients in the control group. Multivariate analysis showed that for locoregional recurrence, radiotherapy and age below 60 years were significant favourable prognostic factors. INTERPRETATION: Postoperative radiotherapy in stage-1 endometrial carcinoma reduces locoregional recurrence but has no impact on overall survival. Radiotherapy increases treatment-related morbidity. Postoperative radiotherapy is not indicated in patients with stage-1 endometrial carcinoma below 60 years and patients with grade-2 tumours with superficial invasion.

Evaluation of late morbidity in patients with carcinoma of the uterine cervix following a dose rate change.

BACKGROUND: A retrospective analysis of late complications for patients with cervical cancer treated with two different brachytherapy schedules in one institute, using the French-Italian glossary. MATERIALS AND METHODS: From 1979 until 1986, a total of 77 patients were treated with external radiation followed by two intracavitary applications with the Gynatron Cs-137 afterloading (dose rate 0.54 Gy/h). After 1986, 66 patients received intracavitary applications with Selectron-LDR (dose rate 1.07 Gy/h). Because of the expected increase in complications with increasing dose rate, the dose per application was reduced from 25 Gy to 20 Gy. RESULTS: 49/77 late gastrointestinal and urinary complications were scored in the Gynatron group and 46/68 in the Selectron group. Actuarial estimates at 5 years showed 42% and 54.1% late gastrointestinal complications and 16.9% and 24.1% for late urinary complications in the patients treated with, respectively, the Gynatron and Selectron. CONCLUSIONS: Despite the dose reduction, there remains a clear dose rate influence on the late morbidity. Correction for this influence is essential.

Late radiotherapeutic morbidity in patients with carcinoma of the uterine cervix: the application of the French-Italian glossary.

BACKGROUND AND PURPOSE: The aim of this study was to perform a retrospective analysis of the complications observed and the importance of delayed symptoms for radiotherapeutic morbidity in patients treated by radiotherapy alone for cervical cancer. MATERIALS AND METHODS: From 1979 to 1991, 145 patients with primary uterine cervical cancer were treated with external radiotherapy and intracavitary applications. During the follow-up, all signs, symptoms and therapy of late treatment complications were recorded. Complications were graded according to the French-Italian glossary. This glossary is used for recording morbidity after treatment of gynaecological cancer. RESULTS: Overall, 119 late complications were recorded. They were most frequently located in the gastro-intestinal system (53%) with a median time to development of 9 months. Urinary complications were recorded in 20%. Very few complications were recorded in vagina/uterus (12%) and pelvic soft tissue (5%). The probability of surviving without tumour recurrence and/or late combined moderate to severe organ morbidity decreased with increasing FIGO stage. CONCLUSIONS: For reporting gynaecological morbidity, the French-Italian glossary is useful. Treatment optimization must take into account actuarial estimates of survival and morbidity.
