- BACKGROUND: It is unclear whether the increasing incidence of thyroid cancer (TC) due to increased diagnosis of small and indolent tumours might mask a real increase of clinically significant cancers. The aim of this study was to correlate surgery, pathology and outcome data of individual patients to the mode of primary detection (palpation, by imaging or incidental) to assess if TC incidence has increased. METHODS: The Swedish Cancer Registry identified all patients with TC in Västra Götaland County representing approximately 1.6 million inhabitants. Clinical information was retrieved from medical records of patient cohorts from three study intervals (2001-2002, 2006-2007 and 2011-2014) comprising 60 per cent of all TC patients. Data were also obtained from the NORDCAN registry to compare of TC incidence with other Nordic countries. RESULTS: Between 2001 and 2014, the annualized standard incidence rate/100 000 population (ASR) of TC increased from 3.14 to 10.71 in women and from 1.12 to 3.77 in men. This was higher than the mean incidence for Sweden but similar to that in Norway and Finland. Differentiated TC (DTC) increased more than threefold. The majority of tumours (64 per cent) were detected by palpation. Larger tumours (10-20, 21-40 and greater than 40 mm) increased as much as microcarcinomas (less than 10 mm). Only 5 per cent of the tumours were detected by imaging. All disease-specific deaths (8.5 per cent of DTC in the first two cohorts) and most patients with recurrent or persistent disease (6.6 per cent of DTC cases) were diagnosed due to tumour-related symptoms. CONCLUSION: DTC in Western Sweden gradually increased between 2001 and 2014. The majority of tumours were detected by palpation suggesting a real increase in the incidence of clinically significant thyroid malignancies. © The Author(s) 2021.

- Objectives: To evaluate whether clinical follow-up programs of oral potentially malignant disorders (OPMD) result in earlier detection and improved survival rates if malignant transformation occurs, as compared to OPMD patients without follow-up and other patients with oral squamous cell carcinoma (OSCC). Materials and methods: Three OSCC groups were retrospectively studied for disease stage at diagnosis and survival rates (N = 739): Group A, patients with OSCC with regular follow-up of preceding OPMD (N = 94); Group B, patients with OSCC with preceding OPMD but no follow-up (N = 68); Group C, patients with OSCC without previously known OPMD diagnosis (N = 577). Results: The patients with OPMD with follow-up (Group A) was diagnosed at a significantly earlier stage and have significantly higher survival rates compared to Group B (p < 0.001 and p = 0.022, respectively) and Group C (p < 0.001 and p < 0.001, respectively). There was no significant difference between Group B and Group C in terms of survival rate (p = 0.143) or stage at diagnosis (p = 0.475). Patients with OPMD and follow-up (Group A) had a 5-year net survival rate of 90.0% (95%CI 80.3-100.8%), as compared to 68.3% percent (95% CI 54.5-85.7) for Group B and 56.1% (95% CI 51.4-61.3) for Group C. Conclusion: The results of this study indicate that regular follow-up of patients with OPMD results in earlier detection of OSCC (if malignant transformation occurs) and improved survival.

- Objective. To evaluate surgical outcomes and survival after primary robotic or open surgery in obese women with endometrial cancer (EC). Methods. The study included obese women (BMI >= 30 kg/m(2)) with EC who underwent primary surgery before and after the introduction of robotics between 2006 and 2014. Data on complications, survival, and recurrence was obtained through the National Cancer Registry and medical files. Survival curves were calculated for overall (OS), relative (RS) and disease-free survival (DFS). Cox proportional hazards regression models to assess OS and DFS. Results. In total, 217 patients were identified, 131 robotic and 86 open surgical procedures. Significantly lower estimated blood loss, surgical time and hospital stay were found in the robotic group and the relative risk ratio of complications grades II-V, using the Clavien Dindo classification, was 0.54 (95% CI 0.31-0.93) for the robotic compared to the open group. A significant difference in OS (p = 0.029) and RS (p = 0.024) in favor of robotics was shown in the univariable survival curves, using log rank tests. No difference was seen for DFS. The 5-year RS was 96.2% (95% CI 89.7-103.3) for the robotic and 81.6% (95% CI 72.1-92.3) for the open group. Multivariable analysis showed high risk histology to be an independent risk factor, for both OS (HR 2.90; 95% CI 1.42-5.93; p < 0.05) and DFS (HR 2.74; 95% CI 1.45-5.17; p < 0.05). Robotic surgery was not found a significant independent factor for survival. Conclusions. Robotic surgery in obese women with EC had equivalent long-term and disease-free survival compared to open with significantly less complications, lower estimated blood loss, shorter surgical time and hospital stay.

- Introduction: Primary surgery for vulvar cancer has become less radical in past decades. This study investigates risk factors and prevalence of short-and long-term complications after up-to-date vulvar cancer surgery. Methods: Population-based cohort study of surgically treated primary vulvar cancer at a national center of vulvar cancer, assessing surgical outcome. The Swedish Quality Registry for Gynecological Cancer was used for identification, journals reviewed and surgical outcome including complications within 30 days and one year registered. Multivariable logistic regression analysis comprising risk factors of short-term complications; age>80 years, BMI, smoking, diabetes, lichen sclerosus and FIGO stage was performed. Results: 182 patients were identified, whereas 55 had vulvar surgery only, 53 surgery including sentinel lymph node biopsy (SLNB) and 72 surgery including inguinofemoral lymphadenectomy (IFL), with short-term complication rates of 21.8%, 39.6% and 54.2% respectively. Vulvar wound dehiscence was reported in 6.0% and infection in 13.7%. Complication rates were lower after SLNB than IFL (wound dehiscence 0% vs 8.3%; p = 0.04, infection 15.1% vs 36.1%; p = 0.01 and lymphocele 5.7% vs 9.7%; p = 0.52). Severe complications were rare. Persisting lymphedema evolved in 3.8% after SLNB and in 38.6% after IFL (p = 0.001), ubiquitous after adjuvant radiotherapy. In multivariable regression analysis, no associations between included risk factors and complications were found. Conclusion: Surgical complications are still common in vulvar cancer surgery and increase with the extent of groin surgery. To thrive for early diagnosis and to avoid IFL seem to be the most important factors in minimizing short-and long-term complications. © 2022

- Objective: To investigate surgical complications related to the staging procedure for endometrial cancer (EC) and to explore complication associations towards patient characteristics and survival. Methods: A population-based cohort study of women diagnosed with EC where primary surgery was performed at a tertiary centre between 2012 and 2016. The Swedish Quality Registry for Gynecological Cancer was used for identification, medical records reviewed and surgical outcomes, including complications according to Clavien-Dindo (CD), and comorbidity (Charlson's index) registered. Uni-and multivariable logistic regression analyses were performed with complications as outcome and multi variable Cox regression analysis with overall survival (OS) as endpoint. Results: In total 549 women were identified where 108 (19.7%) had CD grade II-V complications. In the multivariable regression analysis; surgical technique, BMI and lymph node dissection, but not comorbidity or age, were found to be risk factors for complications CD grade II-V, with OR of 0.32 (95%CI:0.18-0.56) for minimalinvasive surgery (MIS) compared to open, OR 2.18 (95%CI:1.37-3.49) for BMI >30 and OR 2.63 (95%CI:1.32-5.31) for pelvic and paraaortic lymphnode dissection. In Cox regression analysis, a significant lower OS was found within the first 1.5 years for the cohort of complications (CD II-V) compared to no complications. Conclusion: Surgical staging with lymphadenectomy was found a risk factor for complications together with high BMI in EC. Using MIS was significantly associated with less complications. Overall survival was found to be negatively affected within the first years after complications. Our results may be taken into consideration when performing updated treatment guidelines including surgical staging. (c) 2021 The Authors. Published by Elsevier Ltd.
