    Several biomarkers have been preferred for the early diagnosis of pancreatic adenocancer (PAC), but most are not ready to be included as part of the routine diagnostic algorithm because they still lack sensitivity, specificity or reproducibility. CA19-9 is the most widely used serum-based marker for the diagnosis and follow-up of pancreatic cancer. However, CA19-9 lacks sensitivity for early or small-diameter pancreatic cancers. For more than 3 decades, information on neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV) has been widely available to health care practitioners, as part of the data provided in the full blood count. However, these biomarkers have more than used in the routine. The present chapter shares the prognostic significance of the hematological parameters in the light of our own findings and recent studies in the literature

    In patients with gastric cancer, surgical resection is the only treatment that can offer cure or increase long-term survival. With the accumulation of experience in laparoscopic radical gastrectomy and the progress in surgical instruments, laparoscopic surgery for gastric cancer has gained popularity despite initial concerns regarding safety and oncological adequacy. As a result, laparoscopic technique has been widely applied in gastric cancer. Different meta-analyses showed that laparoscopic procedures are associated with less blood loss but longer operation time. Many studies have reported outcomes of laparoscopic surgery for early gastric cancer, but several authors also have shown that a laparoscopic approach can also be used in cases of advanced gastric cancer. We therefore conducted this study to expand our experience and to evaluate laparoscopic gastrectomy step by step in the light of recent reports while defining key points and surgical technique

    WOS: 000438781200010Introduction: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been increasingly performed in many advanced centers of our country. Short-term quality of life (QoL) after the CRS with HIPEC was investigated in Turkish population. The purpose of our study was to investigate the QoL in patients operated for peritoneal carcinomatosis (PC). Methods: Retrospectively collected data from 42 consecutive patients, who had undergone CRS and HIPEC, and 92 abdominal malignancy patients after oncological surgery without CRS and HIPEC were selected in the study between 2012 and 2015. A Turkish version of the European Organization for Research and Treatment of Cancer questionnaire (QLQ-C30) was used at the 6th month following surgery for the QoL assessment. Statistical analysis was done with one sample t-test, and p0.05). Conclusion: Short-term QoL after the CRS with HIPEC patients and without the CRS+HIPEC oncologic patients is found to be similar in Turkish population

    ERAS is a protocol consisting of multidisciplinary approaches, including patient education, fluid resuscitation, keeping patients' innormothermic state, early feeding, and mobilization. We aimed to present and compare the postoperative results of patients operated on due to locally advanced gastric cancer who received neoadjuvant therapy in two high-volume tertiary centers, and aimed to present that ERAS protocols can be applied with success without increasing the complication rate. This retrospective study consisted of two groups: a non-ERAS group and an ERAS group. The ERAS group consisted of 106 patients and the non-ERAS group consisted of 104 patients. The time to first flatus was shorter in the ERAS group compared with the non-ERAS group: 2.8 (1-5) and 3.5 (1-5, p = 0.008), respectively. The average stay at the hospital was 9 (7-22) days in thenon-ERAS group and 6.5 (5-14) days in the ERAS group. Readmission to the hospital within first 15 days after discharge was observed in one (%0.9) patient in the non-ERAS group and in four (%3.8) patients in the ERAS group. ERAS protocols contribute positively to the nutritional status of patients by reducing surgical stress and the rate of hospitalization, and reducing health costs. However, it appears to be associated with increased readmission rates

    WOS: 000432449900005PubMed ID: 29768536Purpose:To compare platelet rich plasma (PRP) and fibrin glue aboutthe effect of anastomotic healing. Methods: Thirty six Wistar-Albino male rats diveded into 3 groups accord ingto control(Group1), PRP (Group 2) and fibrin glue(Tisseel VH) (Group 3). The colon was transected with scissor and subsequently an end to end anastomosis was performed using continuous one layer 6/0 vicryl sutures. Postoperative 7th day effect of anastomotic healing measuring with tissue hydroxyproline(TH) level and anastomotic bursting pressure(ABP); moreover comparison of cytokine (IL-6 and IL-10) and procalcitonin levels on 1st,3rd and 7th days. Results: There was no statistically significant difference of the ABP and hydroxyproline levels between PRP and fibrin glue on the 7th day. There was no statistically significant difference between levels of proinflammatory cytokine (IL-6) (P=0.41), anti-inflammatory cytokine (IL-10) (P=0.35), and procalcitonin levels (P=0.63) on 1, 3 and 7 days. Conclusion: Fibrin glue and platelet rich plasma are shown to be effective in healing intestinal anastomoses without superior to each other

    <div><p>Abstract Purpose: To evaluate the efficacy of nivolumab and comparison with dacarbazine (DTIC) on peritoneal carcinomatosis of malignant melanoma in mouse model. Methods: Mouse skin melanoma cells was injected under the capsule of the peritoneal surface in the left side of the abdomen. On postoperative day ten, mouses randomised into three groups. Group 1: Control, Group 2: HIPEC (Hyperthermic intraperitoneal chemotherapy) with DTIC and Group 3: HIPEC with Nivolumab. After the sacrification on postoperative day fifteen, peritoneum evaluated macroscopically and histopathologically by using peritoneal regression grading score (PRGS). Results: In the 15th day exploration, all animals developed extensive intraperitoneal tumor growth in Group 1. In Group 2 and Group 3 median tumor size was 0.7±0.3cm and 0.3±0.2cm respectively (p: 0.023). Peritoneal carcinomatosis index (PCI) were significantly lower in Group 3 than other groups (p: 0.019). The lowest total tumor nodules in group 3 was 4 ± 2. The PGRS score was found significantly lower in Group 3 than other groups (p: 0.03). Lymphocytic response rate was found higher in the Group 3. Conclusions: It has been found that nivolumab significantly better than DTIC on peritoneal metastases of malign melanoma in mouse models. Nivolumab treatment gives promising results with pathological evidence in the treatment of metastatic disease of malignant melanoma.</p></div

    Diagnostic biomarkers based on epigenetic changes such as DNA methylation are promising tools for early cancer diagnosis. However, there are significant difficulties in directly and specifically detecting methylated DNA regions. Here, we report an electrochemical sensing system based on magnetic nanoparticles that enable a quantitative and selective analysis of the methylated septin9 (mSEPT9) gene, which is considered a diagnostic marker in early stage colorectal cancer (CRC). Methylation levels of SEPT9 in CRC samples were successfully followed by the selective recognition ability of a related peptide nucleic acid (PNA) after hybridization with DNA fragments in human patients&rsquo; serums and plasma (n = 10). Moreover, this system was also adapted into a point-of-care (POC) device for a one-step detection platform. The detection of mSEPT9 demonstrated a limit of detection (LOD) value of 0.37% and interference-free measurement in the presence of branched-chain amino acid transaminase 1 (BCAT1) and SRY box transcription factor 21 antisense divergent transcript 1 (SOX21-AS1). The currently proposed functional platform has substantial prospects in translational applications of early CRC detection

    Background: The optimal treatment of anastomotic leak after rectal cancer resection is unclear. This worldwide cohort study aimed to provide an overview of four treatment strategies applied. Methods: Patients from 216 centres and 45 countries with anastomotic leak after rectal cancer resection between 2014 and 2018 were included. Treatment was categorized as salvage surgery, faecal diversion with passive or active (vacuum) drainage, and no primary/secondary faecal diversion. The primary outcome was 1-year stoma-free survival. In addition, passive and active drainage were compared using propensity score matching (2: 1). Results: Of 2470 evaluable patients, 388 (16.0 per cent) underwent salvage surgery, 1524 (62.0 per cent) passive drainage, 278 (11.0 per cent) active drainage, and 280 (11.0 per cent) had no faecal diversion. One-year stoma-free survival rates were 13.7, 48.3, 48.2, and 65.4 per cent respectively. Propensity score matching resulted in 556 patients with passive and 278 with active drainage. There was no statistically significant difference between these groups in 1-year stoma-free survival (OR 0.95, 95 per cent c.i. 0.66 to 1.33), with a risk difference of -1.1 (95 per cent c.i. -9.0 to 7.0) per cent. After active drainage, more patients required secondary salvage surgery (OR 2.32, 1.49 to 3.59), prolonged hospital admission (an additional 6 (95 per cent c.i. 2 to 10) days), and ICU admission (OR 1.41, 1.02 to 1.94). Mean duration of leak healing did not differ significantly (an additional 12 (-28 to 52) days). Conclusion: Primary salvage surgery or omission of faecal diversion likely correspond to the most severe and least severe leaks respectively. In patients with diverted leaks, stoma-free survival did not differ statistically between passive and active drainage, although the increased risk of secondary salvage surgery and ICU admission suggests residual confounding
