Challenges and Solutions in Choosing the Surgical Treatment in Patients with Complicated Colon Cancer Operated in an Emergency - A Retrospective Study.

Introduction: Choosing the optimal treatment for patients with complicated colon cancer operated in an emergency remains a challenge. The study aims to identify the factors that influence the therapeutic decision in these patients. Patients and Methods: We included in this retrospective study 449 patients operated in emergency for complicated colon cancer, in the Clinical Emergency County Hospital "St. Ap. Andrei" Galati between 2008-2017. The patients data were collected from the observation sheets, the surgical, imaging and laboratory protocols. Results: The operations performed were: resections with a stoma in 37.63% of cases, resections with anastomosis in 36.97%, stomas in 16.26% and internal derivations in 9.13% of patients. Elderly age was correlated with stomas with or without tumour resection (p 0.05). Preoperative diagnosis of IDH was associated with resections with anastomosis, those with occlusion were associated with internal derivations and those with digestive perforations with resections with a stoma (p 0.05). The stomas were associated with the presence of intraoperatively detected complications (p 0.05). Conclusions: Complicated colon tumours operated on in an emergency require surgical treatment tailored to each patient. It is important to choose the type of treatment taking into account the patient's condition at admission, clinical-paraclinical data, tumour location, tumour complication and the presence of other complications detected intraoperatively.

The Influence of the Type of Surgery on the Immediate Postoperative Results in Patients with Colorectal Cancer Operated in Emergency.

The emergency surgery for colorectal cancer is associated with high rates of morbidity and mortality due to factors related to the characteristics of the patients but also the therapeutic attitude. This study aims to identify the surgical interventions associated with the postoperative complications, with the main causes of morbidity, with the reinterventions and with the postoperative deaths. We included in this retrospective study 431 patients hospitalized and operated in an emergency for complicated colorectal malignant tumors in the Surgery II Clinic of the Clinical Emergency County Hospital "Sf. Ap. Andrei from Galati, in the period 2008-2017. The patients data were collected from observation sheets, operative protocols, pathological, imaging and laboratory bulletins, at the time of the emergency intervention, as well as from those of subsequent admissions in patients who benefited from serial interventions. The postoperative morbidity was 10.44%. The resections with anastomosis were associated with the presence of postoperative complications (p 0.01): pseudomembranous colitis, (p 0.01) and postoperative intestinal occlusion (p 0.01). The practice of lymph node dissection was associated with postoperative complications (p 0.01): pseudomembranous colitis (p 0.01) and intestinal occlusion (p 0.01). The reinterventions were associated with resections with anastomosis (p 0.01), lymph node dissection (p 0.01) or patients with open /semi-open abdomen (p 0.04). The postoperative mortality was 9.28%. It was associated with the practice of lymph node dissection (p 0.01), of the ileostomy (p 0.01), with the open /semi-open abdomen (p 0.04). Patients with colostomy had the lowest number of hospitalization days (p 0.01). The resections with anastomosis per primam and the lymph node dissection were associated with morbidity. The type of main surgery did not influence the postoperative mortality, this being associated with the concomitant surgery: the lymph node dissection, the ileostomy, and the abdomen closure type. The reinterventions were associated with resections with anastomosis per primam, with lymph node dissection and with the open /semi-open abdomen. The duration of hospitalization was significantly shorter in patients with a colostomy.

Analysis of Prognostic Factors in Complicated Colorectal Cancer Operated in Emergency.

Introduction: In 2018, the colon cancer was the 5th type of neoplasia regarding the cancer mortality and the rectal cancer was the 10th. The survival of patients with colorectal cancer operated in emergency still remains unsatisfactory, the death being due to local recurrences and to metastases. The aim of this study is to evaluate some correlations of overall survival with clinic and paraclinic features, tumor or treatment characteristics in order to identify prognostic factors, for cases with colorectal tumors that underwent emergency surgery. Material and Methods: We performed a retrospective analysis on 431 patients with colorectal cancer operated in emergency between 2008-2017, excluding 40 patients with postoperative deaths, with a follow-up period of at least one year. There were correlations of some clinic and paraclinic features, tumor or treatment characteristics with the overall survival. Results: In the univariate statistical survival analysis, a statistically significant association was obtained with: the age 61 years (p_value = 0.000049), abdominal surgical history (p_value = 0.031725), heart disease (p_value = 0.000007), atrial fibrillation (p_value = 0.007496), preoperative diagnosis (p_value = 0.034352), cachexia (p_value = 0.000000), oliguria (p_value = 0.000000), anemia (p_value = 0.000006) hydro-electrolytic disorders (p_value = 0.000001), tumor localization (p_value = 0.000030), invasion into other organs (p_value = 0.000000), appearance of "frozen pelvis" (p_value = 0.000000), peritoneal carcinomatosis (p_value = 0.000000), liver metastases (p_value = 0.000000), type of surgery (p_value = 0.000000), lymph node dissection (p_value = 0.000001), liver biopsy (p_value = 0.043483), stoma reversal (p_value = 0.000000 ), serial interventions (p_value = 0.000000), pTNM (p_value = 0.000000), tumor grading (p_value = 0.007069). The Cox multivariate regression analysis revealed that: the age 61 years - HR = 1,026, 95% CI (1,012, 1,039) (p value = 0.000139), cachexia - HR = 1,358, 95% CI (1,046, 1,764) (p value = 0.021617), peritoneal carcinomatosis - HR = 2.346, 95% CI (1.163, 4.732) (p_value = 0.017253), disease stage - HR = 36.745, 95% CI (14.778, 91.366) (p_ value = 0.000000), intervention type - HR = 0.187, 95% CI (0.045, 0.779) (p_ value = 0.021281) and serial interventions - HR = 0.282, 95% CI (0.144.0.551) (p_ value = 000213) are independent prognostic factors. Conclusions: The prognostic factors for patients with colorectal cancers operated in emergency are: the age 61, the presence of abdominal surgical history and associated cardiac conditions, especially atrial fibrillation, diagnosis of diastatic perforation imminence, cachexia, oliguria, hydro-electrolytic disorders at admission, rectal tumors, tumor invasion in other organs, the appearance of "frozen pelvis", the presence of liver metastases or peritoneal carcinomatosis, undifferentiated tumors, stage IV, practicing an internal derivation or not performing lymph node dissection. The age over 61, cachexia, as well as peritoneal carcinomatosis, stage III or IV are independent risk factors the Hartmann procedure and the serial interventions are independent protective factors.

The Importance of Systemic Inflammation Markers in the Survival of Patients with Complicated Colorectal Cancer, Operated in Emergency.

Introduction: The inflammatory response plays a critical role in carcinogenesis. There are recent scores based on the systemic inflammatory response, such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), which have been shown to have prognostic value in cancer patients. These scores allow the identification of patients who will have poor response to treatment and poor survival. The aim of this study is to evaluate the prognostic role of NLR, PLR, LMR and PNI in terms of long-term survival in patients with colorectal cancer, operated in emergency. Material and Methods: We included 391 patients admitted and operated for complicated colorectal cancer in the Surgery II clinic of the Clinical Emergency County Hospital Sf. Ap. Andrei - from Galati, between 2008-2017. We analyzed the paraclinical factors of systemic inflammation NLR, PLR, MRL and PNI. As prognostic factors, survival curves were analyzed. Results: The high values of NLR and PLR increased the risk of death (HR = 7.581, 95% CI = (6.358,9.039), p value = 0.000000, respectively HR = 1.043, 95% CI = (1.039, 1.047), p value = 0.000000), and the increased values of LMR and PNI led to the decrease of this risk (HR = 0.069, 95% CI = (0.054.0.090), p value = 0.000000, respectively HR = 0.758, 95 % CI = (0.730.0.788), p value = 0.000000). In the multivariate regression analysis, the increase of PLR resulted in an increase in the risk of death (HR = 1.024, 95% CI = (1.019.1.029), p value = 0.000000), and for the LMR and PNI, a reduction of the risk of death (HR = 0.353, 95% CI = (0.248.0.504), p value = 0.000000, respectively HR = 0.852, 95% CI = (0.822.0.883), p value = 0.000000). Conclusions: The univariate analysis showed that NLR and PLR are risk factors, and LMR and PNI are protective factors in terms of survival. The multivariate analysis revealed that PLR is an independent risk factor, and LMR and PNI were independent protection factors.
