Bohne A, Grundler E, Knüttel H, Fürst A, Völkel V. Influence of Laparoscopic Surgery on Cellular Immunity in Colorectal Cancer: A Systematic Review and Meta-Analysis. Cancers (Basel) 2023; 15:3381. [PMID: 37444491 DOI: 10.3390/cancers15133381] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 06/22/2023] [Accepted: 06/25/2023] [Indexed: 07/15/2023] Open
Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide. The main treatment options are laparoscopic (LS) and open surgery (OS), which might differ in their impact on the cellular immunity so indispensable for anti-infectious and antitumor defense. MEDLINE, Embase, Web of Science (SCI-EXPANDED), the Cochrane Library, Google Scholar, ClinicalTrials.gov, and ICTRP (WHO) were systematically searched for randomized controlled trials (RCTs) comparing cellular immunity in CRC patients of any stage between minimally invasive and open surgical resections. A random effects-weighted inverse variance meta-analysis was performed for cell counts of natural killer (NK) cells, white blood cells (WBCs), lymphocytes, CD4+ T cells, and the CD4+/CD8+ ratio. The RoB2 tool was used to assess the risk of bias. The meta-analysis was prospectively registered in PROSPERO (CRD42021264324). A total of 14 trials including 974 participants were assessed. The LS groups showed more favorable outcomes in eight trials, with lower inflammation and less immunosuppression as indicated by higher innate and adaptive cell counts, higher NK cell activity, and higher HLA-DR expression rates compared to OS, with only one study reporting lower WBCs after OS. The meta-analysis yielded significantly higher NK cell counts at postoperative day (POD)4 (weighted mean difference (WMD) 30.80 cells/µL [19.68; 41.92], p < 0.00001) and POD6-8 (WMD 45.08 cells/µL [35.95; 54.21], p < 0.00001). Although further research is required, LS is possibly associated with less suppression of cellular immunity and lower inflammation, indicating better preservation of cellular immunity.

Abstract
Surgery is usually required to treat colorectal cancer (CRC). Medical technology has advanced, providing various approaches to tackle this disease. Different surgeries are available, such as laparoscopic surgery, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and robotic surgery. Laparoscopic surgery has several benefits including reduced blood loss and shorter recovery time. It can also improve lung function and minimize complications. However, it requires more time to perform and has a higher risk of complications during the procedure. Robotic surgery provides a three-dimensional view of the surgical area allowing for greater precision in rectal surgeries and access to difficult-to-reach pelvic regions. This method utilizes robotics technology which reduces surgical time and speeds up recovery for patients. There are various surgical options available for treating CRC; however, laparoscopic surgery and robotic surgery offer unique advantages despite their own drawbacks. As technology continues to evolve, medical techniques will continue improving existing methods while providing new options resulting in better outcomes for patients. Compared to laparoscopy, robotic surgery has a lower rate of operative conversions and a shorter learning curve. However, it also has some drawbacks, such as a longer docking time, lack of tactile sensation, and higher cost. Therefore, the choice of surgical method should depend on patient characteristics, surgeon preference and expertise, and available resources. Currently, specialized centers offer robotic surgeries which are more expensive and take longer compared to open and laparoscopic approaches. Nonetheless, they are considered safe and feasible when compared to traditional surgery. Short-term outcomes for robotic surgeries are better, while long-term postoperative complication rates remain similar. However, there is a need for additional well-defined randomized control trials conducted across multiple centers to validate the use of robotic surgery over open and laparoscopic approaches. Improving patient care and outcomes is the objective of this comprehensive literature overview on surgical approaches for CRC.

Abstract
For patients with colorectal cancer, minimally invasive surgical methods, particularly laparoscopic methods, are now the preferred course of therapy. This research is performed to investigate the effects of laparoscopic radical resection on patients with colorectal cancer. A total of 100 colorectal cancer patients treated in our hospital from January 2017 to January 2019 were enrolled. The subjects were divided into observation (n = 50) and control (n = 50) groups and treated with laparoscopic surgery and laparotomy, respectively. As well as postoperative complications and survival rates, the levels of inflammatory substances, stress response, immunological function, and perioperative markers were compared between the two groups. There was no significant difference in the postoperative exhaust time between the two groups (P > 0.05). Compared with the control group, the observation group showed longer operation time, faster recovery of intestinal function, shorter hospital stay, and less intraoperative bleeding amount (P < 0.05). The serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol at 1 d, 3 d, and 5 d after surgery were significantly higher than before in both groups (P < 0.05). Moreover, the serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol in the observation group were significantly lower than that in the control group (P < 0.05). At 10 days following surgery, immune index levels had dramatically increased in both groups, with noticeably higher immune index levels in the observation group than in the control group (P < 0.05). There were no appreciable differences in the two groups' 2-year survival rates (P > 0.05), but the complication rate was much greater in the control group (P < 0.05). To sum up, after laparoscopic surgery, patients had fewer complications, shorter hospital stay, lower inflammatory factor expression, less stress response, better immune function, less trauma, faster recovery, and improved quality of life.

Prediction value of 18F-FDG PET/CT intratumor metabolic heterogeneity parameters for recurrence after radical surgery of stage II/III colorectal cancer. Front Oncol 2022; 12:945939. [PMID: 36158649 PMCID: PMC9493298 DOI: 10.3389/fonc.2022.945939] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 08/12/2022] [Indexed: 11/30/2022] Open
Abstract
Purpose We explored the predictive effect of intratumor metabolic heterogeneity indices extracted from 18F-FDG PET/CT on recurrence in stage II/III colorectal cancer after radical surgery. Methods A total of 140 stage II/III colorectal cancer patients who received preoperative 18F-FDG PET/CT and radical resection were enrolled. 18F-FDG traditional parameters including the maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) under different thresholds; heterogeneity indices including the coefficient of variation with SUV 2.5 as a threshold (CV2.5), CV40%, heterogeneity index-1 (HI-1) calculated by the fixed-threshold method, and HI-2 calculated by the percentage threshold method; and clinicopathological information were collected. We concluded that relationships exist between these data and patients’ disease-free survival (DFS). Results Regional lymph node status (P < 0.001), nerve invasion (P = 0.036), tumor thrombus (P = 0.005), and HI-1 (P = 0.010) exhibited significant differences between the relapse and non-relapse groups, while SUVmax, MTV2.5, MTV40%, TLG2.5, TLG40%, CV2.5, CV40%, HI-2, and other clinicopathological factors had no differences between the relapse and non-relapse groups. Multivariate analysis demonstrated that HI-1 (HR = 1.02, 1.00–1.04, P = 0.038), regional lymph node metastasis (HR = 2.95, 1.37–6.38, P = 0.006), and tumor thrombus status (HR = 2.37, 1.13–4.99, P = 0.022) were independent factors significantly related to DFS. Conclusion HI-1, tumor thrombus status, and regional lymph node status could predict the recurrence of stage II/III colorectal cancer after radical resection and had an advantage over other 18F-FDG PET/CT conventional parameters and heterogeneity indices.

NK and cells with NK-like activities in cancer immunotherapy-clinical perspectives. Med Oncol 2022; 39:131. [PMID: 35716327 DOI: 10.1007/s12032-022-01735-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 04/13/2022] [Indexed: 01/10/2023]
Abstract
Natural killer (NK) cells are lymphoid cells of innate immunity that take important roles in immune surveillance. NK cells are considered as a bridge between innate and adaptive immunity, and their infiltration into tumor area is related positively with prolonged patient survival. They are defined as CD16+ CD56+ CD3- cells in clinic. NK cells promote cytolytic effects on target cells and induce their apoptosis. Loss of NK cell cytotoxic activity and reduction in the number of activating receptors are the current issues for application of such cells in cellular immunotherapy, which resulted in the diminished long-term effects. The focus of this review is to discuss about the activity of NK cells and cells with NK-like activity including natural killer T (NKT), cytokine-induced killer (CIK) and lymphokine-activated killer (LAK) cells in immunotherapy of human solid cancers.

An experimental animal study. Ann Med Surg (Lond) 2022; 75:103398. [PMID: 35386811 PMCID: PMC8977895 DOI: 10.1016/j.amsu.2022.103398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Accepted: 02/21/2022] [Indexed: 11/28/2022] Open
Abstract
Background Radical prostatectomy, a standard management approach for localized Prostate Cancer (PC), may cause a stress response associated with immune modulating effects. Regional anesthesia was hypothesized to reduce the immune effects of surgery by minimizing the neuroendocrine surgical stress response, thus mitigating tumor cells dissemination. Our primary objective was to investigate whether the use of spinal blocks attenuates PC tumor cells dissemination on an animal model. We also assessed the number of circulating NK cells and the amount of inflammatory and anti-inflammatory cytokines. Materials and methods A subcutaneous tumor model, with PC-3M cell line transfected with a luciferase-producing gene (PC-3M-luc-C6) was used. After proper tumor establishment and before tumors became metastatic, animals were submitted to tumor excision surgeries under general or combined (general and spinal) anesthesia. A control group was only anesthetized with general anesthesia. Results The subcutaneous tumor model with PC-3M-luc-C6 cells was effective in causing distant metastasis after 35 days. The number of circulating tumor cells increased in animals that underwent surgery under general anesthesia alone compared to the group submitted to combined anesthesia. Interleukin 6 levels were different in all groups, with increase in the general anesthesia group. Conclusion Our results suggest that combination of spinal and general anesthesia may attenuate the suppression of innate tumor immunity and it might be related to a reduction in the neuroendocrine response to surgery. Institutional protocol number Animal Ethics Committee 1332/2019. Regional anesthesia is related to a reduction in the neuroendocrine response to surgery. Spinal anesthesia combined with general anesthesia modulates Circulating Tumor Cells and cytokines after tissue damage. General anesthesia combined to spinal block could reduce cancer cells dissemination in the postoperative period.

Abstract
Objective To explore the efficacy and safety of laparoscopic radical resection of colorectal cancer in the elderly patients and its impact on gastrointestinal function. Methods A total of 122 elderly patients with colorectal cancer admitted to our hospital from March 2020 to June 2021 were selected as the research subjects, and they were divided into the control group (n = 61) and the observation group (n = 61). The control group was treated with traditional laparotomy, and the observation group was treated with laparoscopic radical resection of colorectal cancer. The clinical data of operation time, incision length, intraoperative bleeding volume, and hospitalization time in the two groups were recorded. Serum motilin (MTL) and gastrin (GAS) levels were measured pre- and post-operatively. The duration of abdominal distension, the time for the abdominal sound to return to normal, the time for the anal exhaust to normal, and the time for normal food intake were recorded after operation. The patients were followed up for 6 months post-operatively, and the complications during follow-up were recorded. Results The total response rate of the observation group (95.08%) was higher than that of the control group (81.97%) (P < 0.05). The operation time, incision length, intraoperative bleeding volume, and hospitalization time of the observation group were lower than those of the control group (P < 0.05). The duration of abdominal distension, the time for bowel sounds to return to normal, the time for the anus to exhaust gas to normal, and the normal eating time in the observation group were all lower than those in the control group (P < 0.05). After surgery, the levels of MTL and GAS in the two groups were lower than those before surgery, and those in the observation group were lower than those in the control group (P < 0.05). The total incidence of complications in the observation group (3.28%) was lower than that in the control group (13.12%) (P < 0.05). Conclusion Laparoscopic radical resection of colorectal cancer in the elderly patients has good effect, short operation time, less trauma, less blood loss during operation, short hospital stay, good recovery of gastrointestinal function, fewer complications, and high safety.

Abstract
Purpose To explore the application effect of fast track surgery (FTS) care combined with continuous care after discharge in patients with laparoscopic cholecystectomy (LC). Methods Two hundred patients treated with LC in our hospital from May 2020 to September 2021 were selected and divided into the routine group receiving routine care (n = 100) and the combined group receiving FTS care combined with continuous care after discharge (n = 100) according to their care methods. We observed the care effect, surgical stress levels [epinephrine, cortisol, Hamilton anxiety scale (HAMA)], postoperative recovery (time to first exhaust, time to first meal, time to first getting out of bed, time to hospitalization), complications, SF-36 scores after discharge, and care satisfaction in both groups. Results The total efficiency of care in the combined group was better than that in the routine group (P < 0.05). At 1 d after surgery, the levels of epinephrine and cortisol in both groups were significantly higher than those at 1 h before surgery, and the HAMA scores were significantly lower than those at 1 h before surgery, and the combined group was lower than the routine group (P < 0.05). The time to first exhaustion, time to first meal, time to first getting out of bed, and time to hospitalization were shorter in the combined group than in the routine group (P < 0.05). The overall complication rate in the combined group was lower than that in the routine group (P < 0.05). The each item of SF-36 scores after discharge were higher in the combined group than in the routine group (P < 0.05). The total satisfaction with care was higher in the combined group than in the routine group (P < 0.05). Conclusion The implementation of FTS care combined with continuous care after discharge in LC patients is ideal, which can significantly reduce the level of surgical stress, accelerate the recovery process, and reduce the occurrence of complications, and improve the postoperative quality of life of patients significantly, and with high satisfaction, which is worthy of application.

Abstract
Purpose Intratumor metabolic heterogeneity parameters on 18F-2-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) have been proven to be predictors of the clinical prognosis of cancer patients. The study aimed to examine the correlation between 18F-FDG PET-CT-defined heterogeneity parameters and the prognostic significance in patients with colorectal cancer. Methods The study included 188 patients with colorectal cancer who received surgery and 18F-FDG PET/CT examinations. Preoperative 18F-FDG PET/CT conventional and metabolic heterogeneity parameters were collected, including maximum, peak, and mean standardized uptake value (SUVmax, SUVpeak, and SUVmean), metabolic tumor volume (MTV), total lesion glycolysis (TLG), heterogeneity index-1 (HI-1) and heterogeneity index-2 (HI-2), and clinicopathological information. Correlations between these parameters and patient survival outcomes were inferred. Results The associations between 18F-FDG PET/CT parameters and clinical outcomes were analyzed. Tumor thrombus (P < 0.001), tumor stage (P=0.001), MTV (P=0.003), HI-1 (P=0.032), and HI-2 (P=0.001) differed between the two groups with and without recurrence. Multivariate analysis showed that, in the radical surgery group, HI-2 (HR = 1.10, 95% CI: 1.04–1.17, P=0.001), tumor stage (HR = 20.65, 95% CI: 4.81–88.62, P < 0.001), and regional lymph nodes status (HR = 0.16, 95% CI: 0.04–0.57, P=0.005) were independent variables significantly correlated with progression-free survival (PFS) and HI-2 (HR = 1.16, 95% CI: 1.07–1.26, P < 0.001) was an independent variable affecting overall survival (OS). In the palliative surgery group, HI-2 (HR = 1.03, 95% CI: 1.01–1.06, P=0.020) was an independent variable affecting PFS, and all the parameters were not statistically significant for OS. Conclusion HI-2, tumor stage, and regional lymph nodes status might predict the outcomes of colorectal cancer more effectively than other 18F-FDG PET/CT defined parameters.

Abstract
Despite advances in cancer treatments, surgery remains one of the most important therapies for solid tumors. Unfortunately, surgery promotes angiogenesis, shedding of cancer cells into the circulation and suppresses anti-tumor immunity. Together this increases the risk of tumor metastasis, accelerated growth of pre-existing micro-metastasis and cancer recurrence. It was theorized that regional anesthesia could influence long-term outcomes after cancer surgery, however new clinical evidence demonstrates that the anesthesia technique has little influence in oncologic outcomes. Several randomized controlled trials are in progress and may provide a better understanding on how volatile and intravenous hypnotics impact cancer progression. The purpose of this review is to summarize the effect of the anesthesia techniques on the immune system and tumor microenvironment (TME) as well as to summarize the clinical evidence of anesthesia techniques on cancer outcomes.
