Day-care laparoscopic cholecystectomy with diathermy hook versus fundus-first ultrasonic dissection : a randomized study

To examine the impact of day-care laparoscopic cholecystectomy (LC) with ultrasonic scissors dissection versus diathermy hook dissection method in a randomized setting. From April 2012 to September 2014, a total of 169 elective day-care patients were randomized to undergo either laparoscopic cholecystectomy with ultrasonic scissors using fundus-first approach (n = 88) or diathermy hook dissection starting from the triangle of Calot (n = 79). Main measures of outcome were operative time, same-day discharge and intraoperative complications. Secondary outcome measures were postoperative pain (numeric rating scale), postoperative nausea and vomiting (PONV), readmissions and 30-day morbidity. Median operative time was similar in the ultrasonic dissection and diathermy hook dissection groups (45 vs 45 min, p = 0.95). Same-day discharge was possible in 77 patients (87 %) in the ultrasonic dissection group and in 69 patients (87 %) in the diathermy group, p = 0.98. Intraoperative gallbladder perforations, mean intraoperative bleeding, postoperative pain and PONV at 1, 2 and 4 h (p = 0.78) did not differ significantly between the study groups. Day-care LC using either diathermy hook or ultrasonic dissection resulted in excellent same-day discharge in both groups (87 %). LC with ultrasonic dissection does not offer any clinical advantages compared to diathermy dissection.Peer reviewe

Impact of Age and Comorbidity on Multimodal Management and Survival from Colorectal Cancer: A Population-Based Study

This retrospective population-based study examined the impact of age and comorbidity burden on multimodal management and survival from colorectal cancer (CRC). From 2000 to 2015, 1479 consecutive patients, who underwent surgical resection for CRC, were reviewed for age-adjusted Charlson comorbidity index (ACCI) including 19 well-defined weighted comorbidities. The impact of ACCI on multimodal management and survival was compared between low (score 0–2), intermediate (score 3) and high ACCI (score ≥ 4) groups. Changes in treatment from 2000 to 2015 were seen next to a major increase of laparoscopic surgery, increased use of adjuvant chemotherapy and an intensified treatment of metastatic disease. Patients with a high ACCI score were, by definition, older and had higher comorbidity. Major elective and emergency resections for colon carcinoma were evenly performed between the ACCI groups, as were laparoscopic and open resections. (Chemo)radiotherapy for rectal carcinoma was less frequently used, and a higher rate of local excisions, and consequently lower rate of major elective resections, was performed in the high ACCI group. Adjuvant chemotherapy and metastasectomy were less frequently used in the ACCI high group. Overall and cancer-specific survival from stage I-III CRC remained stable over time, but survival from stage IV improved. However, the 5-year overall survival from stage I–IV colon and rectal carcinoma was worse in the high ACCI group compared to the low ACCI group. Five-year cancer-specific and disease-free survival rates did not differ significantly by the ACCI. Cox proportional hazard analysis showed that high ACCI was an independent predictor of poor overall survival (p < 0.001). Our results show that despite improvements in multimodal management over time, old age and high comorbidity burden affect the use of adjuvant chemotherapy, preoperative (chemo)radiotherapy and management of metastatic disease, and worsen overall survival from CRC

Immunoscore in mismatch repair-proficient and -deficient colon cancer

The aim of this study was to investigate immune response and its prognostic significance in colon carcinomas using the previously described Immunoscore (IS). A population-based series of 779 colorectal cancers, operated on between 2000 and 2010, were classified according to tumour, node, metastasis (TNM) status, mismatch repair (MMR), and BRAF mutation status. Rectal cancer cases (n = 203) were excluded as a high proportion of these patients received preoperative neoadjuvant chemoradiotherapy. Tissue microarray (TMA) samples collected from the tumour centre and invasive front were immunostained for CD3 and CD8. Lymphocytes were then digitally calculated to categorize IS from grade 0 to 4. Samples adequate for IS were available from 510 tumours. IS was significantly associated with AJCC/UICC stage, T stage, lymph node and distant metastases, perineural and lymphovascular invasion, MMR status, and BRAF mutation status. For IS0, IS1, IS2, IS3 and IS4, respectively, the 5-year disease-free survival (DFS) rates were 59, 68, 78, 83 and 94% (p Peer reviewe

Laparoscopic Colectomy vs Laparoscopic CME : a Retrospective Study of Two Hospitals with Comparable Laparoscopic Experience

Purpose To compare laparoscopic non-CME colectomy with laparoscopic CME colectomy in two hospitals with similar experience in laparoscopic colorectal surgery. Methods Data was collected retrospectively from Paijat-Hame Central Hospital (PHCH, NCME group) and Central Finland Central Hospital (CFCH, CME group) records. Elective laparoscopic resections performed during 2007-2016 for UICC stage I-III adenocarcinoma were included to assess differences in short-term outcome and survival. Results There were 340 patients in the NCME group and 325 patients in the CME group. CME delivered longer specimens (p <0.001), wider resection margins (p <0.001), and more lymph nodes (p <0.001) but did not result in better 5-year overall or cancer-specific survival (NCME 77.9% vs CME 72.9%, p = 0.528, NCME 93.2% vs CME 88.9%, p = 0.132, respectively). Thirty-day morbidity, mortality, and length of hospital stay were similar between the groups. Conversion to open surgery was associated with decreased survival. Discussion Complete mesocolic excision (CME) is reported to improve survival. Most previous studies have compared open CME with open non-CME (NCME) or open CME with laparoscopic CME. NCME populations have been historical or heterogeneous, potentially causing bias in the interpretation of results. Studies comparing laparoscopic CME with laparoscopic NCME are few and involve only small numbers of patients. In this study, diligently performed laparoscopic non-CME D2 resection delivered disease-free survival results comparable with laparoscopic CME but was not safer.Peer reviewe

Immunophenotype based on inflammatory cells, PD-1/PD-L1 signalling pathway and M2 macrophages predicts survival in gastric cancer

BackgroundImmune response against cancer has prognostic impact but its role in gastric cancer is poorly known. The aim of the study was to assess the prognostic significance of immune cell score (CD3+, CD8+), tumour immune escape (PD-L1, PD-1) and immune tolerance (Clever-1). MethodsAfter exclusion of Epstein-Barr virus positive (n = 4) and microsatellite instable (n = 6) tumours, the study included 122 patients with GC undergoing D2 gastrectomy. CD3+ and CD8+ based ICS, PD-L1, PD-1 and Clever-1 expressions were evaluated. Differences in survival were examined using Cox regression adjusted for confounders. The primary outcome was 5-year survival. Results The 5-year overall survival rate was 43.4%. High ICS was associated with improved overall survival (adjusted HR 0.48 (95% CI 0.26-0.87)) compared to low ICS. In the high ICS group, patients with PD-L1 expression (5-year survival 69.2 vs. 53.1%, p = 0.317), high PD-1 (5-year survival 70.6 vs. 55.3% p = 0.312) and high Clever-1 (5-year survival 72.0% vs. 45.5% (p = 0.070) had poor prognosis. Conclusions High ICS was associated with improved survival. In the high ICS group, patients with high PD-L1, PD-1 and Clever-1 had poor prognosis highlighting the importance of immune escape and immune tolerance in GC.</p

Repeated centralized multidisciplinary team assessment of resectability, clinical behavior, and outcomes in 1086 Finnish metastatic colorectal cancer patients (RAXO): A nationwide prospective intervention study

Background: Resection of colorectal cancer (CRC) metastases provides good survival but is probably underused in real-world practice.Methods: A prospective Finnish nationwide study enrolled treatable metastatic CRC patients. The intervention was the assessment of resectability upfront and twice during first-line therapy by the multidisciplinary team (MDT) at Helsinki tertiary referral centre. The primary outcome was resection rates and survival.Findings: In 2012-2018, 1086 patients were included. Median follow-up was 58 months. Multiple metastatic sites were present in 500 (46%) patients at baseline and in 820 (76%) during disease trajectory. In MDT assessments, 447 (41%) were classified as resectable, 310 (29%) upfront and 137 (18%) after conversion therapy. Sixhundred and ninety curative intent resections or local ablative therapies (LAT) were performed in 399 patients (89% of 447 resectable). Multiple metastasectomies for multisite or later developing metastases were performed in 148 (37%) patients. Overall, 414 liver, 112 lung, 57 peritoneal, and 107 other metastasectomies were performed. Median OS was 80.4 months in R0/1-resected (HR 0.15; CI95% 0.12-0.19), 39.1 months in R2-resected/LAT (0.39; 0.29-0.53) patients, and 20.8 months in patients treated with "systemic therapy alone" (reference), with 5-year OS rates of 66%, 40%, and 6%, respectively.Interpretation: Repeated centralized MDT assessment in real-world metastatic CRC patients generates high resectability (41%) and resection rates (37%) with impressive survival, even when multisite metastases are present or develop later. </p
