Rehospitalisations, repeated aortic surgery, and death in initial survivors of surgery for Stanford type A aortic dissection and the significance of age - a nationwide registry-based cohort study.

AIMS: Describe and compare incidences across age groups of rehospitalization, repeated aortic surgery, and death in patients who survived surgery and hospitalization for type A aortic dissection. METHODS AND RESULTS: From Danish nationwide registries, we identified patients hospitalized with Stanford type A aortic dissections (2006-2018). Survivors of hospitalization and surgery on the ascending aorta and/or aortic arch comprised the study population (n = 606, 36 (38.9%) <60 years old (group I), 194 (32.0%) 60-69 years old (group II), and 176 (29.1%) >69 years old (group III)). During the first year, 62.5% were re-hospitalized and 1.4% underwent repeated aortic surgery with no significant differences across age groups (P = 0.68 and P = 0.39, respectively). Further, 5.9% died (group I: 3.0%, group II: 8.3%, group III: 7.4%, P = 0.04). After 10 years, 8.0% had undergone repeated aortic surgery (group I: 11.5%, group II: 8.5%, group III: 1.6%, P = 0.04) and 10.2% (group I), 17.0% (group II), and 22.2% (group III) had died (P = 0.01). Using multivariable Cox regression analysis, we described long-term outcomes comparing age groups. No age differences were found in one-year outcomes, while age > 69 years compared with age < 60 years was associated with a lower rate of repeated aortic surgery [hazard ratio 0.17, 95% confidence interval (CI) 0.04-0.78] and a higher rate of all-cause mortality (hazard ratio 2.44, 95% CI 1.37-4.34) in the 10-year analyses. CONCLUSION: Rehospitalisations in the first year after discharge were common in all age groups, but survival was high. Repeated aortic surgery was significantly more common among younger than older patients.

Case Report: Abdominal Lymph Node Metastases of Parathyroid Carcinoma: Diagnostic Workup, Molecular Diagnosis, and Clinical Management.

Parathyroid carcinoma (PC) is an orphan malignancy accounting for only ~1% of all cases with primary hyperparathyroidism. The localization of recurrent PC is of critical importance and can be exceedingly difficult to diagnose and sometimes futile when common sites of recurrence in the neck and chest cannot be confirmed. Here, we present the diagnostic workup, molecular analysis and multimodal therapy of a 46-year old woman with the extraordinary manifestation of abdominal lymph node metastases 12 years after primary diagnosis of PC. The patient was referred to our endocrine tumor center in 2016 with the aim to localize the tumor causative of symptomatic biochemical recurrence. In view of the extensive previous workup we decided to perform [18F]FDG-PET-CT. A pathological lymph node in the liver hilus showed slightly increased FDG-uptake and hence was suspected as site of recurrence. Selective venous sampling confirmed increased parathyroid hormone concentration in liver veins. Abdominal lymph node metastasis was resected and histopathological examination confirmed PC. Within four months, the patient experienced biochemical recurrence and based on high tumor mutational burden detected in the surgical specimen by whole exome sequencing the patient received immunotherapy with pembrolizumab that led to a biochemical response. Subsequent to disease progression repeated abdominal lymph node resection was performed in 10/2018, 01/2019 and in 01/2020. Up to now (12/2020) the patient is biochemically free of disease. In conclusion, a multimodal diagnostic approach and therapy in an interdisciplinary setting is needed for patients with rare endocrine tumors. Molecular analyses may inform additional treatment options including checkpoint inhibitors such as pembrolizumab.

Primary pleural synovial sarcoma with repeated resection leading to long-term survival.

Primary pleural synovial sarcoma is a malignant tumour and thought to be more aggressive than synovial sarcoma which occurs in extremities. Its treatment strategy has not been fully established because of its rarity. We report a primary pleural synovial sarcoma case which achieved a long-term survival with repeated surgery of recurrent pleural tumour. A 39-year-old man presented with a gradually enlarged tumour in the left hemithorax. The tumour was resected and diagnosed as primary pleural synovial sarcoma. The tumour was slowly growing and repeatedly recurrent in the left pleura. The surgical resections for the recurrent tumours were performed 6 years and 11 years after the initial surgery. Intriguingly, recurrent tumour which developed after second surgery exhibited temporally spontaneous regression. Our patient remains alive 12 years after the initial surgery. Repeated resection of metastatic lesion can achieve long survival in primary pleural synovial sarcoma.

Survival after repeated surgery for lung cancer with idiopathic pulmonary fibrosis: a retrospective study.

BACKGROUND: Patients with idiopathic pulmonary fibrosis (IPF) have a high risk of developing lung cancer, but few studies have investigated the long-term outcomes of repeated surgery in such patients. The purpose of this study was to evaluate the surgical outcomes of repeated lung cancer surgery in patients with IPF. METHODS: From January 2001 to December 2015, 108 lung cancer patients with IPF underwent pulmonary resection at two institutions; 13 of these patients underwent repeated surgery for lung cancer, and their data were reviewed. RESULTS: The initial procedures of the 13 patients were lobectomy in 8, segmentectomy in 2, and wedge resection in 3. The subsequent procedures were wedge resection in 10 and segmentectomy in 3. The clinical stage of the second tumor was stage IA in 12 and stage IB in 1. Postoperatively, 3 patients (23.1%) developed acute exacerbation (AE) of IPF and died. The rate of decrease in percent vital capacity was significantly higher in patients with AE than in those without AE (p = 0.011). The 3-year overall survival rate was 34.6%. The causes of death were cancer-related in 7, AE of IPF in 3, and metachronous lung cancer in 1. CONCLUSIONS: Despite limited resection, a high incidence of AE was identified. The early and long-term outcomes of repeated surgery in lung cancer patients with IPF were poor because of the high risk of AE of IPF and lung cancer recurrence. Long-term intensive surveillance will be required to determine whether surgical intervention is justified in patients with multiple primary lung cancers and IPF.

Reoperation for pelvic organ prolapse: a Danish cohort study with 15-20 years' follow-up.

INTRODUCTION AND HYPOTHESIS: The objectives were to determine the reoperation rate of primary pelvic organ prolapse (POP) surgery, to describe the age distribution of the women at primary surgery for those undergoing a reoperation, and to describe the incidence of second and third reoperations. METHODS: We carried out a population-based registry study of Danish women above the age of 18 years when undergoing primary surgery for POP during the period 1996-2000. Data were retrieved from the Danish National Patient Register. All women were followed until one of the following events occurred: reoperation for POP, death, emigration, or end of follow-up period. Reoperation was defined as "repeated surgery in same compartment". The cumulative incidence rate of reoperation was divided into three compartments (anterior, apical, and posterior) and was calculated using Kaplan-Meier plots. RESULTS: A total of 18,382 procedures were performed on 11,805 women. After 20 years' follow-up, the cumulated incidence rate of reoperation for POP in the anterior, apical, and posterior compartments was 12.4%, 7.9%, and 12.1% respectively. The overall rate of reoperation was 11.5%. Of women aged between 18 and 49 years of age at primary surgery, 26.9% had a reoperation, whereas in women between 50 and 90+ years of age at primary surgery, only 10.1% had a reoperation. CONCLUSIONS: This large study with up to 20 years' follow-up has found that reoperation for POP is modest, that the reoperation rate is lowest for the apical compartment, but highest in all three compartments during the first year after primary surgery. The reoperation rate peaks in the group of women who had their primary surgery before the menopause in all three compartments.

Repeated surgeries in invasive lobular breast cancer with preoperative MRI: Role of additional carcinoma in situ and background parenchymal enhancement.

OBJECTIVES: Analysing the influence of additional carcinoma in situ (CIS) and background parenchymal enhancement (BPE) in preoperative MRI on repeated surgeries in patients with invasive lobular carcinoma (ILC) of the breast. METHODS: Retrospective analysis of 106 patients (mean age 58.6±9.9years) with 108 ILC. Preoperative tumour size as assessed by MRI, mammography and sonography was recorded and compared to histopathology. In contrast-enhanced MRI, the degree of BPE was categorised by two readers. The influence of additionally detected CIS and BPE on the rate of repeated surgeries was analysed. RESULTS: Additional CIS was present in 45.4% of the cases (49/108). The degree of BPE was minimal or mild in 80% of the cases and moderate or marked in 20% of the cases. In 17 cases (15.7%) at least one repeated surgery was performed. In n=15 of these cases, repeated surgery was performed after BCT (n=9 re-excisions, n=6 conversions to mastectomy), in n=2 cases after initial mastectomy. The initial surgical procedure (p=0.008) and additional CIS (p=0.046) significantly influenced the rate of repeated surgeries, while tumour size, patient age and BPE did not (p=ns). CONCLUSIONS: Additional CIS was associated with a higher rate of repeated surgeries, whereas BPE had no influence.

Objective outcome and quality-of-life assessment in women with repeat incontinence surgery.

AIMS: To evaluate subjective and objective outcome after repeat surgery for stress urinary incontinence (SUI). METHODS: Patients who underwent a midurethral tape after failed Burch colposuspension or failed midurethal tape between 1999 and 2014 were invited for follow-up. Urogynecological examination and urodynamics was performed, and objective cure was defined as a negative cough stress test; subjective cure was defined as negotiation of SUI symptoms. Quality-of-life (QoL), sexual health, and subjective success was assessed with the King's Health Questionnaire, Incontinence Outcome Questionnaire, Female Sexual Function Index, and the Patient Global Impression of Improvement (PGI-I) score. RESULTS: Overall 52 women underwent repeat incontinence surgery. Out of the 44 women still alive, 33 (75%) were available for follow-up. All 33 women completed the questionnaires; 23 women (70%) attended the clinic and also had an urogynecological examination. At a median follow-up of 11 years, subjective cure was 67% (22/33), objective cure was 65% (16/23), and subjective success according to PGI-I was 78% (18/23), with no significant differences between groups. No erosions of suture or tape material into the bladder, urethra, or vagina were seen. Two women had received a third anti-incontinence operation with TVT after failed tape after failed Burch, and were continent at follow-up. Two women with tape after colposuspension required division of the tape and both were continent at the time of follow-up. With regard to QoL and sexual health, no significant differences were seen for most domains. CONCLUSIONS: Midurethral tapes are an option for women with recurrent SUI after previous colposuspension or midurethral tape.

Quality-of-Life Differences among Diagnostic Subgroups of Children Receiving Ventilating Tubes for Otitis Media.

OBJECTIVE: The pathological picture may differ considerably between diagnostic subgroups of children with otitis media receiving ventilating tubes. The aims of this study are to investigate differences in quality of life among diagnostic subgroups of children treated with ventilating tubes and to investigate possible predictors for clinical success. STUDY DESIGN: Longitudinal observational study. SETTING: Secondary care units. METHODS: Four hundred ninety-one families were enrolled in the study. The Otitis Media-6 questionnaire was applied in the assessment of child quality of life. Caregivers completed questionnaires at 7 time points from before treatment to 18-month follow-up. Logistic regression analysis was used to investigate possible predictors for clinical success. RESULTS: Response rates ranged from 96% to 81%; diagnostic distribution: 15% recurrent acute otitis media (rAOM), 47% otitis media with effusion (OME), and 38% mixed diagnosis of rAOM and OME (rAOM/OME). There were no significant differences between children diagnosed with rAOM and children diagnosed with rAOM/OME. However, these children had a significantly poorer quality of life at baseline compared with children diagnosed with only OME. Factors associated with clinical success included a diagnosis of rAOM, number of interrupted nights, physician visits, and canceled social activities due to OM. CONCLUSIONS: Results highlight the importance of distinguishing between diagnostic subgroups of children having ventilating tube treatment. A diagnosis of rAOM was found to predict baseline quality of life. Children with rAOM with or without OME were found to suffer significantly more than children with only OME before treatment. Factors associated with disease severity were found to predict clinical success.
