Background
Recent clinical practice guidelines recommend that routine screening of MEN1 mutation carriers should start at the age of 5 years. The occurrence of clinically relevant MEN1 organ manifestations in children (≤18 years) was evaluated.Methods
Two prospective collected databases of MEN1 patients (n = 166) who underwent annual screening were retrospectively analyzed for organ manifestations in MEN1 patients ≤18 years. The follow-up was based on the most recent screening examination until December 2015.Results
Twenty [11 females, 9 males, (12%)] of 166 MEN1 patients were diagnosed with at least one organ manifestation at age ≤18 years. The most frequent manifestation was mild asymptomatic pHPT (n = 9, 45%, age range 8–18 years). Eight (40%) young patients had pNENs (three non-functioning pNENs, five insulinomas, age range 9–18 years). All five insulinomas were diagnosed based on hypoglycemic symptoms. The other organ manifestations were asymptomatic pituitary adenomas in six patients (30%, age range 15–18 years) and a bronchial carcinoid in one 15-year-old patient. Only six (30%) patients ≤18 years had clinically relevant organ manifestations.Conclusion
Symptomatic or severe manifestations in MEN1 patients rarely occur below the age of 16 years. With regard to psychological burden and cost-effectiveness, routine screening of asymptomatic MEN1 patients should be postponed at least until the age of 16 years.2.

Background
Primary hyperparathyroidism is the most common manifestation of multiple endocrine neoplasia type 1 (MEN1). Guidelines advocate subtotal parathyroidectomy (STP) or total parathyroidectomy with autotransplantation due to high prevalence of multiglandular disease; however, both are associated with a significant risk of permanent hypoparathyroidism. More accurate imaging and use of intraoperative PTH levels may allow a less extensive initial parathyroidectomy (unilateral clearance, removing both parathyroids with cervical thymectomy) in selected MEN1 patients with primary hyperparathyroidism.Methods
We performed a retrospective cohort study at a high-volume tertiary medical center including patients with MEN1 and primary hyperparathyroidism, who underwent STP or unilateral clearance as their initial surgery from 1995 to 2015. Unilateral clearance was offered to patients who had concordant sestamibi and ultrasound showing a single enlarged parathyroid gland. For both the groups, we compared rates of persistent/recurrent disease and permanent hypoparathyroidism.Results
Eight patients had unilateral clearance and 16 had STP. Subtotal parathyroidectomy patients were younger (37 vs 52 years). One patient in each group had persistent disease. One (13 %) unilateral clearance and five (31 %) STP patients had recurrent hyperparathyroidism after a mean follow-up of 47 and 68 months (p = 0.62). No unilateral clearance patients and two of 16 SPT patients had permanent hypoparathyroidism (p = 0.54).Conclusions
Some MEN1 patients with primary hyperparathyroidism who have concordant localizing studies may be selected for unilateral clearance as an alternative to STP. For appropriately selected MEN1 patients, unilateral clearance can achieve similar results as STP and has no risk of permanent hypoparathyroidism, and may facilitate possible future reoperations.3.

Background
Primary hyperparathyroidism (HPT) in multiple endocrine neoplasia type 1 (MEN1) is surgically treated with either a subtotal parathyroidectomy removing 3 or 3,5 glands (SPX), less than 3 glands (LSPX), or a total parathyroidectomy with autotransplantation (TPX). Previous studies with shorter follow-up have shown that LSPX and SPX are associated with recurrent HPT, and TPX with hypocalcemia and substitution therapy. We examined the situation after long-term follow-up (median 20,6 years).Methods
Sixty-nine patients with MEN1 HPT underwent 110 operations, the first operation being 31 LSPX, 30 SPX, and 8 TPX. Thirty patients underwent reoperative surgery in median 120 months later, as completion to TPX (n = 12), completion of LSPX to SPX (n = 9), extirpation of single glands (n = 3) still resulting in LSPX, and resection of forearm grafts (n = 3). Nine patients underwent a second, and 2 a third reoperation. In 24 patients genetic testing confirmed MEN1, and in the remaining heredity and phenotype led to the diagnosis.Results
TPX had higher risk for hypoparathyroidism necessitating substitution therapy, at latest follow-up 50 %, compared to SPX (16 % after 3–6 months; none at latest follow-up). Recurrent HPT was common after LSPX, leading to 24 reoperations in 17 patients. No need for substitution therapy after SPX indicated forthcoming recurrent disease. Not having hypocalcemia in the postoperative period and less radical surgery than TPX were significantly associated to risk for recurrence. Further, mutation in exon 3 in the MEN1 gene may eventually be linked to risk of recurrence.Conclusion
LSPX is highly associated with recurrence and TPX with continuous hypoparathyroidism, also after long-term follow-up. SPX should be the chosen method in the majority of patients with MEN1 HPT.4.

Background
Anterior cruciate ligament (ACL) reconstruction is a widely accepted procedure; however, controversies exist about ACL augmentation. The purpose of this study was to assess the clinical outcomes of ACL augmentation in professional and amateur athletes with isolated single bundle ACL tears.Materials and methods
A consecutive series of professional and amateur athletes with partial ACL tears who underwent selective bundle reconstruction were analyzed. Stability was assessed with the Lachman test, anterior-drawer test, pivot-shift test and KT-1000 arthrometer. Functional assessment was performed using the subjective Lysholm questionnaire.Results
Fifty-six patients were enrolled. The mean follow-up period was 19.3 months. All patients had posterolateral bundle (PLB) tears, and no anteromedial bundle (AMB) tears were found. The Lysholm score improved significantly from 78 (SD = 2.69) preoperatively to 96 (SD = 3.41) postoperatively (P value <0.0001). The pivot-shift test, Lachman test and anterior-drawer test results were negative in all cases postoperatively. Anterior tibial translation from neutral was 4.9 mm (SD = 2.7) preoperatively, and decreased significantly to 2.1 (SD = 0.6) postoperatively, measured with a KT-1000 arthrometer (P value <0.00001).Conclusion
In this study, we showed that ACL augmentation had good results in symptomatic professional and amateur athletes, and although further studies are needed to investigate long-term results, we recommend this surgery for all symptomatic athletic patients, especially those who would like to maintain an active lifestyle. Level of evidence IV.5.
Purpose
To determine success rate (SR), functional outcome, and patient satisfaction of a modified YV-plasty for reconstruction of the bladder neck in case of recurrent bladder neck stenosis (BNS) after transurethral surgery of the prostate: the T-plasty.Patients and methods
We identified all patients who underwent T-plasty at our center between December 2008 and July 2016. Patients’ charts were reviewed. Patients were queried by telephone and by mail at time of follow-up (FU). Primary endpoint was SR. Secondary endpoints were complications, continence, satisfaction, and changes in quality of life measured by validated questionnaires.Results
Thirty patients underwent the T-plasty. Median age at surgery was 69 (IQR 62–73) years. Most patients had BNS due to TUR-P [n = 25 (83.3%)]. No severe blood loss or severe complications occurred perioperatively. Median FU was 45 (IQR 18–64) months. Three patients were lost to FU. Success rate was 100%. Compared to pre-OP Q max, mean Q max post-OP improved significantly [pre-OP 6.79 (SD ± 4.76) ml/s vs post-OP was 24.42 (SD ± 12.61) ml/s; (t(5) = 4.12, p = 0.009)]. Mean post-void residual urine decreased significantly [pre-OP 140.77 (SD ± 105.41) ml vs post-OP 14.5 (SD ± 22.42) ml; (t(9) = ?3.86, p = 0.004)]. One patient developed a de-novo-incontinence post-OP. Mean ICIQ-SF Score was 1.2 (SD ± 2.27). 88.5% of patients were pleased or delighted by surgery. 75% of patients claimed their quality of life has been (strongly) improved.Conclusions
The T-plasty is a valuable option as treatment of recurrent BNS. SR, rates of continence, and high patient satisfaction are very encouraging.6.
Background
Total extraperitoneal (TEP) hernia repair has been shown to offer less pain, shorter postoperative hospital stay and earlier return to work when compared to open surgery. Our institution routinely performs TEP procedures for patients with primary or recurrent inguinal hernias. The aim of this study was to show that supervised senior residents can safely perform TEP repairs in a teaching setting.Methods
All consecutive patients treated for inguinal hernias by laparoscopic approach from October 2008 to June 2012 were retrospectively analyzed from a prospective database.Results
A total of 219 TEP repairs were performed on 171 patients: 123 unilateral and 48 bilateral. The mean patient age was 51.6 years with a standard deviation (SD) of ± 15.9. Supervised senior residents performed 171 (78 %) and staff surgeons 48 (22 %) TEP repairs, respectively. Thirty-day morbidity included cases of inguinal paresthesias (0.4 %, n = 1), umbilical hematomas (0.9 %, n = 2), superficial wound infections (0.9 %, n = 2), scrotal hematomas (2.7 %, n = 6), postoperative urinary retentions (2.7 %, n = 6), chronic pain syndromes (5 %, n = 11) and postoperative seromas (6.7 %, n = 14). Overall, complication rates were 18.7 % for staff surgeons and 19.3 % for residents (p = 0.83). For staff surgeons and residents, mean operative times for unilateral hernia repairs were 65 min (SD ± 18.9) and 77.6 min (SD ± 29.8) (p = 0.043), respectively, while mean operative times for bilateral repairs were 115 min (SD ± 40.1) and 103.6 (SD ± 25.9) (p = 0.05).Conclusions
TEP repair is a safe procedure when performed by supervised senior surgical trainees. Teaching of TEP should be routinely included in general surgery residency programs.7.
Background
Routine screening is recommended for patients with multiple endocrine neoplasia type 1 (MEN1) to enable early detection and treatment of associated neuroendocrine neoplasms (NEN). Gallium68-DOTATOC-Positron emission tomography combined with computed tomography (Ga-68-DOTATOC-PET-CT) is a very sensitive and specific imaging technique for the detection of sporadic neuroendocrine tumors. The present study evaluated the value of Ga-68-DOTATOC-PET-CT in routine screening of patients with MEN1.Methods
Between January 2014 and March 2016, all MEN1 patients underwent Ga-68-DOTATOC-PET-CT in addition to conventional imaging (computed tomography of the thorax, magnetic resonance imaging of the abdomen and pituitary, endoscopic ultrasonography). The diagnostic yield of conventional imaging and Ga-68-DOTATOC-PET-CT was prospectively documented and compared, and treatment changes caused by the addition of Ga-68-DOTATOC-PET-CT were recorded.Results
Conventional imaging detected 145 NENs, mainly pancreaticoduodenal NENs (n = 117, 81%), in 31 of 33 MEN1 patients. Ga-68-DOTATOC-PET-CT detected 55 NENs in 23 of the 33 patients (p = 0.0001). Ninety (62%) NENs detected by conventional imaging were missed by DOTATOC-PET-CT. The majority of missed lesions were pNEN (n = 68; 74%). The sensitivity of Ga-68-DOTATOC-PET-CT for NENs <5, 5–9, 10–19 and ≥20 mm was 0, 29, 81 and 100%, respectively. However, Ga-68-DOTATOC-PET-CT detected more liver and lymph node metastases in patients with known metastatic disease, which did not lead to a change of patients’ management. In one patient (3%), Ga-68-DOTATOC-PET-CT was the only imaging modality that detected a small intestine NEN and led to potentially curative surgery.Conclusion
Ga-68-DOTATOC-PET-CT cannot be recommended for routine screening of MEN1 patients. It might provide important additional information in patients with suspected or known metastatic disease.8.
Background
There is no consensus opinion on a definitive surgical management option for ranulas to curtail recurrence, largely from the existing gap in knowledge on the pathophysiologic basis.Aim
To highlight the current scientific basis of ranula development that informed the preferred surgical approach.Design
Retrospective cohort study.Setting
Public Tertiary Academic Health Institution.Method
A 7-year 7-month study of ranulas surgically managed at our tertiary health institution was undertaken—June 1, 2008–December 31, 2015—from case files retrieved utilising the ICD-10 version 10 standard codes.Results
Twelve cases, representing 0.4 and 1.2% of all institutional and ENT operations, respectively, were managed for ranulas with a M:F = 1:1. The ages ranged from 5/12 to 39 years, mean = 18.5 years, and the disease was prevalent in the third decade of life. Main presentation in the under-fives was related to airway and feeding compromise, while in adults, cosmetic facial appearance. Ranulas in adults were plunging (n = 8, 58.3%), left-sided save one with M:F = 2:1. All were unilateral with R:L = 1:2. Treatment included aspiration (n = 2, 16.7%) with 100% recurrence, intra-/extraoral excision of ranula only (n = 4, 33.3%) with recurrence rate of 50% (n = 2, 16.7%), while marsupialisation in children (n = 1, 8.3%) had no recurrence. Similarly, transcervical approach (n = 5, 41.7%) with excision of both the ranula/sublingual salivary gland recorded zero recurrence. Recurrence was the main complication (n = 4, 33.3%).Conclusion
With the current knowledge on the pathophysiologic basis, extirpation of both the sublingual salivary gland and the ranula by a specialist surgeon is key for a successful outcome.9.

Objectives
Bariatric surgery is an effective treatment for youth with severe obesity. However, outcomes are variable and there remains sparse understanding of predictors of weight loss following surgery. The current study examines the role of adolescent-reported pre-operative social support around exercise, binge eating, and exercise to predict excess body mass index (EBMI) loss from 3 to 12 months post-surgery.Method
Participants were 101 adolescents ages 12–21 (M age = 16.6, SD = 1.8). Pre-operative body mass index (BMI) ranged from 35 to 87 (M = 50.3, SD = 8.6). Structural equation modeling (SEM) was used to evaluate a model of the association of adolescent report of perceived social support for exercise with less binge eating (items from the Eating Disorder Diagnostic Scale) and more self-reported exercise (items from the Youth Risk Behavior Surveillance System). The model was used to predict EBMI loss at 3, 6, 9, and 12 months post-surgery.Results
Social support significantly predicted exercise and demonstrated a trend for predicting binge eating, such that more social support was associated with more exercise and a trend for less binge eating. Binge eating was associated with less EBMI loss. However, there was no association of exercise with EBMI loss.Conclusions
Pre-operative binge eating should be a target for identification and treatment prior to sleeve gastrectomy in adolescents. Although not directly or indirectly associated with EBMI loss, perceived social support around exercise was associated with increased exercise, which may make it a consideration for a target for intervention as well.11.

Background
Patient-reported outcomes require validation in a particular language and culture before administration for clinical use.Materials and methods
A systematic translation of the IKDC Subjective Knee Form was initially tested in 30 patients with various knee pathologies to develop the first Greek version (IKDC/SKF-GR). It was then administered to another 80 patients. The test–retest reliability (n = 35) and internal consistency (n = 80) were examined. Construct validity was tested by correlating the IKDC/SKF-GR with the SF-36 subscales (n = 80) and content validity by measuring floor/ceiling effects. Responsiveness was measured in patients with meniscus pathology (n = 24).Results
Patients filled the form without omissions/questions regarding the phrasing of items. Internal consistency was good (Cronbach’s α = 0.87) and test–retest reliability very good (ICC2,1 = 0.95, SEM = 4.4 and SDC = 12.2). Correlations with the SF-36 subscales confirmed its construct validity. No floor/ceiling effects were recorded. The effect size was large (ES = 1.26).Conclusions
The IKDC/SKF-GR has comparable measurement properties to the original form.Level of evidence
Level II.12.

Objective
Currently, there is no effective paradigm to identify patients who are at risk for renal dysfunction following cardiac surgery. The specific mechanisms of renal injury during surgery are incompletely understood. The aim of the study was to evaluate whether postoperative renal dysfunction can be predicted from intraoperative glomerular filtration rate (GFR).Design
This is a prospective study.Setting
The study was conducted in a tertiary care multi-specialty hospital.Participants and interventions
GFR was measured in 24 patients (mean age 56.6 ± 11.09 years, 20 male) undergoing elective off-pump coronary artery bypass grafting during preoperative period, intraoperative period, 24 h after surgery (ICU GFR), and on the fifth postoperative day (final GFR ).Measurements and main results
Patients were divided into two groups depending upon changes in intraoperative GFR. Group 1 (n = 10): who had a rise in intraoperative GFR in comparison with preoperative baseline measurement. All these 10 (41.7 %) patients with a rise in intraoperative GFR had an uneventful hospital course and achieved an improvement in final GFR. Group 2 (n = 14): 14 (58.3 %) patients had a fall in intraoperative GFR (mean 36.4 %) in comparison with preoperative baseline value. Of these 14 patients, 1 patient required dialysis support and 3 patients required ionotropic support. Among these 14 patients in group two, 7 had deterioration in final GFR (mean 28.7 %), when compared to preoperative baseline value.Conclusion
Postoperative renal dysfunction can be predicted from intraoperative GFR. Patients who have a rise in intraoperative GFR do not develop postoperative renal dysfunction, and only patients with intraoperative fall in GFR are at risk of postoperative renal dysfunction.13.
Background
Our purpose was to validate the performance of the ISS, NISS, RTS and TRISS scales as predictors of mortality in a population of trauma patients in a Latin American setting.Materials and methods
Subjects older than 15 years with diagnosis of trauma, lesions in two or more body areas according to the AIS and whose initial attention was at the hospital in the first 24 h were included. The main outcome was inpatient mortality. Secondary outcomes were admission to the intensive care unit, requirement of mechanical ventilation and length of stay. A logistic regression model for hospital mortality was fitted with each of the scales as an independent variable, and its predictive accuracy was evaluated through discrimination and calibration statistics.Results
Between January 2007 and July 2015, 4085 subjects were enrolled in the study. 84.2% (n = 3442) were male, the mean age was 36 years (SD = 16), and the most common trauma mechanism was blunt type (80.1%; n = 3273). The medians of ISS, NISS, TRISS and RTS were: 14 (IQR = 10–21), 17 (IQR = 11–27), 4.21 (IQR = 2.95–5.05) and 7.84 (IQR = 6.90–7.84), respectively. Mortality was 9.3%, and the discrimination for ISS, NISS, TRISS and RTS was: AUC 0.85, 0.89, 0.86 and 0.92, respectively. No one scale had appropriate calibration.Conclusion
Determining the severity of trauma is an essential tool to guide treatment and establish the necessary resources for attention. In a Colombian population from a capital city, trauma scales have adequate performance for the prediction of mortality in patients with trauma.14.

Purpose
To identify predictors of both intermediate and long-term unfavorable outcomes after first time, uncomplicated lumbar disc surgery.Methods
Patients (n = 120) who had undergone lumbar disc surgery were followed up 1.5 and 12 years thereafter. Baseline assessments were carried out 5–8 days after surgery. Clinical outcome was assessed in both follow-ups using the Low Back Pain Rating Scale. Statistical analysis included binary logistic and linear regression.Results
Unfavorable outcomes were found in 50.5 % (1.5 years) and 52.6 % (12 years) of patients available for follow-up examination. Low pre-operative physical activity and severe pain in the first week after surgery were predictive of an unfavorable post-operative outcome at both follow-ups.Conclusions
Identified predictors suggest that particular emphasis should put on comprehensive post-operative care at large and encouragement to adapt a physically active lifestyle in particular in rehabilitation concepts after first time uncomplicated lumbar disc surgery.15.
Purpose
Familial adenomatous polyposis (FAP) is a genetic disorder. Some female patients with FAP can become pregnant. However, the current state of childbirth after surgery for FAP is unclear in Japan.Methods
The study investigated 303 patients (147 female) who had undergone surgery for FAP at the 23 institutions between 2000 and 2012.Results
Eighty female patients had information available on childbirth after surgery for FAP. Eight patients (10 %) gave birth after surgery. The mean age at surgery for FAP was 27 (range 20–41) years and 37 years in patients with and without childbirth after surgery, respectively (P = 0.044). The rate of childbirth after surgery was 17 % in women ≤30 years of age and 13 % in those ≤40 years of age. Although only one patient with invasive cancer (2.9 %) gave childbirth after surgery, seven patients without cancer (15.6 %) gave birth (P = 0.045).Conclusions
This study clarified the current state of childbirth after surgery for FAP in Japan. It is important to use these data to determine the best therapeutic approach for female FAP patients.16.
Importance
In resource-limited settings, identification of successful and sustainable task-shifting interventions is important for improving care.Objective
To determine whether the training of lay people to take vital signs as trauma clerks is an effective and sustainable method to increase availability of vital signs in the initial evaluation of trauma patients.Design
We conducted a quasi-experimental study of patients presenting with traumatic injury pre- and post-intervention.Setting
The study was conducted at Kamuzu Central Hospital, a tertiary care referral hospital, in Lilongwe, Malawi.Participants
All adult (age ≥ 18 years) trauma patients presenting to emergency department over a six-month period from January to June prior to intervention (2011), immediately post-intervention (2012), 1 year post-intervention (2013) and 2 years post-intervention (2014).Intervention
Lay people were trained to take and record vital signs.Main outcomes and measures
The number of patients with recorded vital signs pre- and post-intervention and sustainability of the intervention as determined by time-series analysis.Results
Availability of vital signs on initial evaluation of trauma patients increased significantly post-intervention. The percentage of patients with at least one vital sign recorded increased from 23.5 to 92.1%, and the percentage of patients with all vital signs recorded increased from 4.1 to 91.4%. Availability of Glasgow Coma Scale also increased from 40.3 to 88.6%. Increased documentation of vital signs continued at 1 year and 2 years post-intervention. However, the percentage of documented vital signs did decrease slightly after the US-trained medical student and surgeon who trained the trauma clerks were no longer available in country, except for Glasgow Coma Scale. Patients who died during emergency department evaluation were significantly less likely to have vital signs recorded.Conclusions and relevance
The training of lay people to collect vital signs and Glasgow Coma Scale is an effective and sustainable method of task shifting in a resource-limited setting.17.
Background
Thoracoscopic diaphragmatic plication for diaphragmatic paralysis with consecutive eventration and respiratory compromise is a desirable alternative to standard thoracotomy. Since minimally invasive techniques usually involve suturing of the diaphragm, most surgeons use a video-assisted approach with a minithoracotomy. Herein we describe our completely thoracoscopic technique for diaphragmatic plication including outcome.Methods
We present our technique and experience for completely thoracoscopic diaphragmatic plication for the treatment of symptomatic diaphragmatic paralysis in six consecutive patients. The surgical technique basically consisted of stapling of the abundant diaphragm and reinforcement of the staple line using a self-locking thread. Primary outcome measure was the postoperative result (flattened diaphragm) and resolution of symptoms. Secondary outcome was improvement of lung function values 3 months after surgery.Results
Between June 2015 and March 2016, six patients have been operated for symptomatic diaphragmatic paralysis, with one of them suffering from additional transdiaphragmatic hernia. Flattening of the diaphragm was achieved in all 6 patients with resolution of their pre-existing symptoms within days after surgery and without any surgical complications. Lung function volumes measured 3 months postoperative improved markedly with an increase in FEV1 as well as FVC of 540 ml (SD ± 193 ml) and 776 ml (SD ± 121 ml), respectively.Conclusions
In our experience, the presented technique is a safe and simple minimally invasive way to perform a completely thoracoscopic diaphragmatic plication with excellent results so far.18.
Purpose
To compare the outcomes of microendoscopic discectomy and open discectomy for patients with lumbar disc herniation.Methods
An extensive search of studies was performed in PubMed, Medline, Embase, Cochrane library and Google Scholar. The following outcome measures were extracted: visual analogue scale (VAS), Oswestry disability index (ODI), complication, operation time, blood loss and length of hospital stay. Data analysis was conducted with RevMan 5.0.Results
Five randomized controlled trials involving 501 patients were included in this meta-analysis. The pooled analysis showed that there was no significant difference in the VAS, ODI or complication between the two groups. However, compared with the open discectomy, the microendoscopic discectomy was associated with less blood loss [WMD = ?151.01 (?288.22, ?13.80), P = 0.03], shorter length of hospital stay [WMD = ?69.33 (?110.39, ?28.28), P = 0.0009], and longer operation time [WMD = 18.80 (7.83, 29.76), P = 0.0008].Conclusions
Microendoscopic discectomy, which requires a demanding learning curve, may be a safe and effective alternative to conventional open discectomy for patients with lumbar disc herniation.19.

Background and objectives
High rates of recurrence have been observed after curative treatment for hepatocellular carcinoma (HCC). The main aim of this study was to establish the influence of adjuvant transarterial radioembolization-based I-131 lipiodol on survival and recurrence.Methods
Between 2004 and 2010, 38 patients were treated with adjuvant I-131 lipiodol therapy, at a dosage of 2220 MBq, within 4 months after surgery. This treated cohort was compared to a control cohort consisting of 42 consecutive patients operated prior to the time the I-131 lipiodol treatment became available.Results
Recurrence-free survival in the control and in the I-131 lipiodol cohort was 12.6 and 18.7 months, respectively (HR = 1.871, p = 0.025). At 2 and 5 years, the cumulative incidence of a first recurrence or death was, respectively, 50 % and 61 % in the treated cohort versus 69 % and 74 % in the control cohort. Median overall survival was 55 and 29 months, respectively (p = 0.051). Among patients with a recurrence at 2 years, more patients had already experienced such recurrence at 1 year in the control cohort (70 % vs 33 %, p = 0.014).Conclusions
Adjuvant I-131 lipiodol improves disease-free survival in patients with HCC.20.
