Objectives: The objective of this retrospective study was to examine the survival of patients following a diagnosis of primary nonmetastatic colorectal cancer who did not undergo major surgery for the purpose of curative treatment. Design: A retrospective observational study. Study Settings: Department of Colorectal Surgery, King's College Hospital, London. Patient and Methods: A retrospective study of patients with stages I–III colorectal cancer who had not undergone noncurative surgery, palliative chemotherapy, or radiotherapy between 2012 and 2019 was conducted. Multivariate and univariate analyses were used to evaluate the prognostic factors associated with overall survival (OS). Main Outcome Measure: OS. Sample Size: A total of 78 patients. Results: A total of 78 patients were enrolled in this study. The median survival rate was 296 days or 9.7 months, and the mean survival rate was 385 days (15–1894 days). The 1- and 2-year OS rates were 37.2% and 3.8%, respectively. Univariate analysis revealed that three parameters were statistically significant for OS with a significant correlation with performance status (PS) (P = 0.004), tumor stage (pT) (P = 0.030), and lymph node metastasis (pN) (P = 0.001). Multivariate analysis revealed that pN2 (hazard ratio: 2.19, 95% confidence index: -1.1–4.4) and PS 3 and 4 (hazard ratio: 0.525, 95% confidence index: 0.3–1.0, P = 0.026) were prognostic factors associated with OS. Conclusion: Operable colorectal cancer patients without surgical resection have an OS rate of <1 year; a higher T and N stage is associated with adverse prognosis. Limitations: Our study is limited by its retrospective nature and small sample size. In addition, patients underwent various palliative interventions based on their unique clinical, pathological, and social needs.

Natural orifice specimen extraction is defined by the site of extraction and has been performed via the vagina, anal canal, rectum, colon, and mouth. The primary benefit of this technique is reduced trauma at the access point due to avoidance of mini laparotomy, used to facilitate specimen extraction in conventional laparoscopy. This technique has been associated with less postoperative pain, lower analgesic requirement, faster return of bowel function, and fewer incisional hernias, as well as an improved cosmetic result. Use of the robotic platform allows for deep pelvic dissection, which is challenging to impossible with laparoscopic instruments.

Objectives: We aimed to evaluate the effect of LNR (number of metastatic lymph nodes/number of total lymph nodes excised) on disease-free survival and overall survival rates in CRC. Design: A single-center retrospective cohort study. Setting: Tertiary care hospital. Patients and Methods: The clinical and pathological features of the patients were analyzed by dividing them into groups according to tumor localization; tumor, node, metastasis staging; and LNR. The Kaplan–Meier method and the log-rank test were used for survival analysis. Sample Size: A total of 479 patients with CRC who were operated on between September 1991 and December 2011 were included in this study. The LNR of 439 patients could be calculated, and analyses were according to these patient groups. Main Outcome Measures: The primary objective of this study was to determine the effect of LNR on disease-free survival and overall survival in CRC. Results: A total of 121 right-sided colon cancers, 202 left-sided colon cancers, and 156 rectal cancers were analyzed. The age of the patients ranged from 20 to 93 years, and the mean age was 66.8 (13.5) years. The cumulative 5-year survival rate was 48.5% in our patients with CRC. When analyzing the tumor, node, metastasis stages of the groups according to their LNRs, the results showed that as the rate of lymph node metastasis increases, so does the tumor stage parameter (P < 0.001). The overall survival and disease-free survival rates significantly decreased as LNR increased (P < 0.001). Conclusion: This study showed that LNR correlates well with the disease-free and overall survival rates. A higher LNR could indicate the aggressiveness of the tumor; therefore, LNR may be a predictor of the poor prognosis of CRC. Limitations: Some patients could not be followed-up and we could not evaluate complications because not all patients had data on postoperative complications. As a result, our study results may have been affected.

{"title":"Trends of minimally invasive surgery and adequate lymph node harvest in pT4 colon adenocarcinoma: A national cancer database analysis","authors":"Felipe Pacheco, Sarah Harris-Gendron","doi":"10.4103/wjcs.wjcs_8_23","DOIUrl":"https://doi.org/10.4103/wjcs.wjcs_8_23","url":null,"abstract":"Background: Recent advances in minimally invasive surgery (MIS) have improved outcomes in colon cancer treatment. However, the use of MIS in pT4 colon cancer is controversial. Existing literature on lymph node retrieval in MIS compared to that in open surgery is inconsistent. Previous studies using the National Cancer Database from 2010 to 2014 and 2010 to 2016 found that MIS was associated with higher odds of adequate lymph node resection. Objectives: Using data from more recent years, this study seeks to compare lymph node resection between MIS and open surgery in pT4 colon cancer. Design and Setting: This retrospective cohort study was conducted using the National Cancer Database. Patients and Methods: Patients undergoing MIS or open surgery with lymph node harvest for pT4 colon cancer were included in this study. A trend analysis of surgical approach (MIS versus open and robotic versus laparoscopic) from 2010 to 2017 and a logistic regression model including multiple tumor characteristics and demographic variables for procedures between 2015 and 2017 were performed. Main Outcome Measures: The main outcome evaluated was the adequacy of lymph node retrieval. Sample Size: A total of 27319 patients were included. Results: This study showed a trend towards MIS and robotic surgery for pT4 colon cancer. In addition, it found that MIS for pT4 tumors have higher odds of achieving an adequate lymph node harvest than open surgery in recent years (2015–2017). The demographic factors associated with inadequate lymph node harvest include race and location of the facility (rural versus metro cities). Conclusions: The findings of this study suggest that colorectal surgery has shifted towards MIS, and specifically, robotic surgery for pT4 tumors. This approach has an oncological advantage of adequate lymph node harvest compared to open surgery. Limitations: Despite its advantages, this retrospective database study has inherent biases, such as confounding bias, selection bias, and coding errors in the database, as well as limited data available for analysis.

An effective surgical resection plays an integral role in the success or failure of these patients' oncologic treatment. Objective: This study was designed to focus on lymph node sampling and survival of patients undergoing resections for colon cancer to determine if additional training leads to better outcomes. Design: This is a retrospective review from 2006–2017. Patients who presented through the emergency room were considered elective if their surgery was performed >72 hours after admission. One-hundred and thirty-five surgeons were included, and 13 were colorectal trained. We excluded patients with metachronous or synchronous tumors. Analysis was performed using the Wilcoxon rank sum test. Settings: Twenty-three hospitals within a single healthcare system. Patients: Final analysis included patients undergoing a primary, elective resection for colon cancer. Sample Size: We focused at 2335 patients. Main Outcome Measure: Survival after resection and number of lymph nodes sampled. Results: Among the patients, 2657 met the inclusion criteria, with only 322 resections being considered nonelective. In the elective population of 2335 patients, 536 underwent resection by a colorectal specialty trained surgeon. The survival probability was greater for patients who underwent resection by colorectal surgeons than those for patients who underwent resection by non-colorectal surgeons (p = 9e-05). Lymph node sampling in elective resections by colorectal surgeons was significantly higher (p = < 2e-16), with the mean being 23.8 vs 19.1, respectively. Conclusion: Colorectal trained surgeons have significantly better outcomes than non-specialty trained surgeons considering the overall survival rates and number of lymph nodes sampled for elective resections. Limitations: There was insufficient evidence to conclude that any difference existed in the outcomes when considering the non-elective patient population given the low numbers of these resections being performed by colorectal surgeons.
