- AIM: The aim of this study was to evaluate and describe the lymph node ratio (LNR) as a prognostic parameter for patients with colon cancer. As lymphatic involvement is the key, focus was set at stage III disease. Interest was directed at the possibility of identifying high-risk groups and the clinical implementation and consequence. METHOD: The study was retrospective using a database of clinical data of all cancer patients treated at our unit. It has been continuous in registration, inclusion and update since 1999 including survival and clinical features. All patients (n=265) diagnosed with stage III colon cancer during 1999-2003 were included for the study. LNR was calculated and quartile groups were created. LNR and associated parameters were analysed towards 3-year disease-free survival (DFS). Basic patient data as well as surgery, pathology and postoperative treatment were taken into consideration. RESULTS: Significant differences in disease-free survival were found for TNM N-status, tumour differentiation grade and LNR quartile group. There was a difference in 3-year DFS from 80% in LNR group 1 compared with less than 30% in group 4. These results were of prognostic interest both independently and in interaction with each other. High-risk groups could be identified and in the worst prognosis LNR group we also found a tendency towards more side effects with adjuvant chemotherapy. CONCLUSION: The lymph node ratio, the quota between the number of lymph node metastasis and assessed lymph nodes, is a highly significant (p<0.001) prognostic factor in stage III colon cancer. It can be an aid in identifying risk groups that could benefit from a more intense postoperative surveillance and possibly bring changes in adjuvant treatment strategy. More studies of clinical data, genetic and biochemical markers are needed in this patient group to understand the possible difference in tumour behaviour and tailor the treatment.

Tidskriftsartikel (refereegranskat)abstract
- Breast cancer (BC) is the most common female cancer, and as bilateral breast augmentation (BBA) increases, more women are presenting with BC within an augmented breast. No international guidelines exist on how to manage such a situation, so this group undertook a global survey to provide a snapshot of current surgical practice. The key finding was the variable oncoplastic management of BC after BBA: most surgeons responded that when oncologically safe, breast conservation with implant preservation was appropriate as radiotherapy was not a contra-indication to preserving implants. Immediate symmetrisation could be considered but was not always available. We propose a large multicenter observational study to support the development of international guidelines. This will help patients, healthcare funders, providers, and surgeons to optimize care and reduce inequity of access to appropriate oncoplastic surgery options for the increasing number of women with BBA and BC.

- © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology Introduction: Patients with cancer who develop small bowel obstruction are at high risk of malnutrition and morbidity following compromise of gastrointestinal tract continuity. This study aimed to characterise current management and outcomes following malignant small bowel obstruction. Methods: A prospective, multicentre cohort study of patients with small bowel obstruction who presented to UK hospitals between 16th January and 13th March 2017. Patients who presented with small bowel obstruction due to primary tumours of the intestine (excluding left-sided colonic tumours) or disseminated intra-abdominal malignancy were included. Outcomes included 30-day mortality and in-hospital complications. Cox-proportional hazards models were used to generate adjusted effects estimates, which are presented as hazard ratios (HR) alongside the corresponding 95% confidence interval (95% CI). The threshold for statistical significance was set at the level of P ≤ 0.05 a-priori. Results: 205 patients with malignant small bowel obstruction presented to emergency surgery services during the study period. Of these patients, 50 had obstruction due to right sided colon cancer, 143 due to disseminated intraabdominal malignancy, 10 had primary tumours of the small bowel and 2 patients had gastrointestinal stromal tumours. In total 100 out of 205 patients underwent a surgical intervention for obstruction. 30-day in-hospital mortality rate was 11.3% for those with primary tumours and 19.6% for those with disseminated malignancy. Severe risk of malnutrition was an independent predictor for poor mortality in this cohort (adjusted HR 16.18, 95% CI 1.86 to 140.84, p = 0.012). Patients with right-sided colon cancer had high rates of morbidity. Conclusions: Mortality rates were high in patients with disseminated malignancy and in those with right sided colon cancer. Further research should identify optimal management strategy to reduce morbidity for these patient groups.

- Background: Combining hyperthermic intraperitoneal chemotherapy (HIPEC) treatment with early postoperative intraperitoneal chemotherapy (EPIC) may increase postoperative morbidity. This study aims to investigate postoperative morbidity after HIPEC+EPIC compared with HIPEC alone in patients with peritoneal metastases (PM).Materials and methods: This is a retrospective propensity score matched cohort study. All patients undergoing PM treatment at Uppsala University Hospital between February 2004 and December 2014 were included. Propensity score matching with a 1:1 ratio was performed using sex, primary tumor site, preoperative chemotherapy, peritoneal cancer index, completeness of cytoreduction score, and HIPEC regimen. Length of hospital stay, morbidity, reoperation rate, and readmission rate within 6 months were selected as endpoints.Results: A total of 390 consecutive patients were divided in two arms: HIPEC+EPIC (n = 115) and HIPEC alone (n = 275). The propensity score matching (n = 190) was successful with balanced covariates: 95 patients/arm. The length of stay (LOS) was longer in the HIPEC + EPIC group in the total cohort (30 vs 24 days, p < 0.001), with a trend towards significance in the propensity matched group (29 vs 25 days, p = 0.062). No other differences in endpoints were found.Conclusion: HIPEC+EPIC is associated with a prolonged hospital stay, but with no statistically significant relevant increase in postoperative morbidity, reoperation rate or incidence of readmission.

- Background The impact of intraoperative fluid management during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) on postoperative outcomes has been poorly investigated. This study aimed to investigate the impact of intraoperative fluid management strategy on postoperative outcomes and survival focusing on postoperative hemorrhage. Methods 509 patients undergoing CRS and HIPEC at Uppsala University Hospital/Sweden 2004-2017 were categorized into two groups according to the intraoperative fluid management strategy: pre-goal directed therapy (pre-GDT) and goal directed therapy (GDT), where a hemodynamic monitor (CardioQ or FloTrac/Vigileo) was used to optimize fluids management. Impact on morbidity, postoperative hemorrhage, length-of-stay and survival was analyzed. ResultsThe pre-GDT group received higher intraoperative fluid volume compared to the GDT group (mean 19.9 vs. 16.2 ml/kg/h, p<0.001). Overall postoperative morbidity Grade III-V was higher in the GDT group (30% vs. 22%, p=0.03). Multivariable adjusted odds ratio (OR) for Grade III-V morbidity was 1.80 (95%CI 1.10-3.10, p=0.02) in the GDT group. Numerically, more cases of postoperative hemorrhage were found in the GDT group (9% vs. 5%, p=0.09), but no correlation was observed in the multivariable analysis 1.37 (95%CI 0.64-2.95, p=0.40). An oxaliplatin regimen was a significant risk factor for postoperative hemorrhage (p=0.03). Mean length of stay was shorter in the GDT group (17 vs. 26 days, p<0.0001). Survival did not differ between the groups.ConclusionWhile GDT management increased the risk for postoperative morbidity, it was associated with shortened hospital stay. Intraoperative fluid management during CRS and HIPEC did not affect the postoperative risk for hemorrhage, while the use of an oxaliplatin regimen did.

- Background: Preoperative radiotherapy (RT) for rectal cancer reduces local recurrence rates and possibly also mortality. Patient-related parameters such as age and comorbidity have a major impact on selection to preoperative RT. The aim of this study was to investigate how this selection influences the outcome in rectal cancer regardless of dose or fractionation of RT.Methods: Data from the Swedish Colorectal Cancer Registry and the Swedish National Patient Register on all patients without distant metastasis who underwent elective trans-abdominal surgery for rectal cancer 2000-2010 in the Stockholm Gotland region was retrieved. Factors influencing survival and recurrence were identified by Cox regression analyses.Results: There were 2300 patients included. Among these 70.3% received preoperative RT. Three-year overall survival (OS), disease-free survival (DFS) and local recurrence rate were 80.2, 68.6 and 4.7%, respectively. All outcome measures were significantly improved over time. In a multivariable analysis in patients with comorbidity (Charlson comorbidity index score >= 1), OS were significantly better following preoperative RT than after surgery alone (HR 0.65, 95% CI 0.49-0.87). OS among patients with advanced age (>= 80 years), was not influenced by preoperative RT.Conclusion: OS among patients with comorbidity was better following preoperative RT than after surgery alone while no differences were seen among the elderly. This indicates that the selection process may be optimised for the patients with advanced age but comorbidity should be used cautiously for exclusion of patients from preoperative RT.
