RESUMO
INTRODUCTION: baseline neutrophil-to-lymphocyte ratio (NLR) at the time of colorectal cancer (CRC) diagnosis has been proposed as a predictor of long-term survival. The aim of this study was to analyze its usefulness in a homogeneous population with control of the main confounding factors. METHODOLOGY: observational study of 836 patients who underwent surgery for CRC. Patients were divided into two groups: NLR ≤ 3.3 vs NLR > 3.3. To control for confounders, they were matched one-to-one by propensity analysis. A final cohort of 526 patients was included in the study. RESULTS: the two groups were mismatched in terms of age, comorbidity, tumor stage, rectal location, and neoadjuvant therapy. Once matching was performed, baseline NLR was statistically significantly associated with long-term survival (p < 0.001) and behaved as an independent prognostic factor for survival (p = 0.001; HR: 1.99; 95 % CI: 1.32-3.00) when adjusted in a Cox regression model using age (p < 0.001; HR: 1.04; 95 % CI: 1.02-1.06) and the Charlson Comorbidity Index (p < 0.001; HR: 1.40; 95 % CI: 1.27-1.55). Neoadjuvant therapy lost its statistical significance (p = 0.137; HR: 1.59; 95 % CI: 0.86-2.93). CONCLUSIONS: a high baseline NLR (> 3.3) in patients with colorectal cancer at diagnosis represents a poor prognostic factor in terms of survival. Its use in routine practice could intensify therapeutic strategies and follow-up in these patients.

Purpose: Postoperative hypoparathyroidism is the most frequent complication after total thyroidectomy. The identification of preoperative predictors could be helpful to identify patients at risk. The aim of this study is to determine if preoperative vitamin D levels are related to transient, protracted, and permanent hypoparathyroidism. Method: A prospective, observational study that includes 100 patients who underwent total thyroidectomy. Results: Transient hypoparathyroidism was present in 42% of patients, 11% developed protracted hypoparathyroidism and 5% permanent hypoparathyroidism. The median preoperative Vitamin D levels were higher in patients who developed transient hypoparathyroidism than in patients without this complication (24 ng/mL [RIQ 13-31] vs. 17 ng/mL [RIQ 10-24]; p = 0.024). Patients with preoperative vitamin D levels below 20 ng/mL had a lower percentage of transient hypoparathyroidism (31.4% vs. 53.1%; p = 0.028). The prevalence of protracted and permanent hypoparathyroidism in both groups was similar. Patients with preoperative vitamin D levels lower than 20 pg/mL had higher median PTH levels 24 h after surgery, (37.7 ± 28.2 pg/ml vs. 23.6 ± 18.6 pg/ml; p = 0.037), and suffered a lower postoperative PTH decline (46.2 ± 35.4% vs. 61 ± 29%; p = 0.026). Conclusions: Patients with vitamin D deficiency had a lower transient hypoparathyroidism rate, higher median PTH levels 24 h after surgery and a lower postoperative PTH decline. We found no association between preoperative vitamin D and the development of protracted or permanent hypoparathyroidism.
RESUMO
OBJECTIVE: Mesenteric venous thrombosis (MVT) is a rare cause of acute surgical abdomen, with high mortality. The aim of this study was to analyze long-term outcomes and possible factors influencing its prognosis. METHODS: All patients who underwent urgent surgery for MVT from 1990 to 2020 in our center were reviewed. Epidemiological, clinical, and surgical data; postoperative outcomes; origin of thrombosis; and long-term survival were analyzed. Patients were divided into two groups: primary MVT (hypercoagulability disorders or idiopathic MVT) and secondary MVT (underlying disease). RESULTS: Fifty-five patients, 36 (65.5%) men and 19 (34.5%) women, mean age 66.7 years (standard deviation: ±18.0 years), underwent surgery for MVT. Arterial hypertension (63.6%) was the most prevalent comorbidity. Regarding the possible origin of MVT, 41 (74.5%) patients had primary MVT and 14 (25.5%) patients had secondary MVT. From these, 11 (20%) patients had hypercoagulable states, 7 (12.7%) had neoplasia, 4 (7.3%) had abdominal infection, 3 (5.5%) had liver cirrhosis, 1 (1.8%) patient had recurrent pulmonary thromboembolism, and 1 (1.8%) had deep venous thrombosis. Computed tomography was diagnostic of MVT in 87.9% of the cases. Intestinal resection was performed in 45 patients due to ischemia. Only 6 patients (10.9%) had no complication, 17 patients (30.9%) presented minor complications, and 32 patients (58.2%) presented severe complications according to the Clavien-Dindo classification. Operative mortality was 23.6%. In univariate analysis, comorbidity measured by the Charlson index (P = .019) and massive ischemia (P = .002) were related to operative mortality. The probability of being alive at 1, 3, and 5 years was 66.4%, 57.9%, and 51.0%, respectively. In univariate analysis of survival, age (P < .001), comorbidity (P < .001), and type of MVT (P = .003) were associated with a good prognosis. Age (P = .002; hazard ratio: 1.05, 95% confidence interval: 1.02-1.09) and comorbidity (P = .019; hazard ratio: 1.28, 95% confidence interval: 1.04-1.57) behaved as independent prognostic factors for survival. CONCLUSIONS: Surgical MVT continues to show high lethality. Age and comorbidity according to the Charlson index correlate well with mortality risk. Primary MVT tends to have a better prognosis than secondary MVT.

Cancer is a devastating disease and the second leading cause of death worldwide. However, the development of resistance to current therapies is making cancer treatment more difficult. Combining the multi-omics data of individual tumors with information on their in-vitro Drug Sensitivity and Resistance Test (DSRT) can help to determine the appropriate therapy for each patient. Miniaturized high-throughput technologies, such as the droplet microarray, enable personalized oncology. We are developing a platform that incorporates DSRT profiling workflows from minute amounts of cellular material and reagents. Experimental results often rely on image-based readout techniques, where images are often constructed in grid-like structures with heterogeneous image processing targets. However, manual image analysis is time-consuming, not reproducible, and impossible for high-throughput experiments due to the amount of data generated. Therefore, automated image processing solutions are an essential component of a screening platform for personalized oncology. We present our comprehensive concept that considers assisted image annotation, algorithms for image processing of grid-like high-throughput experiments, and enhanced learning processes. In addition, the concept includes the deployment of processing pipelines. Details of the computation and implementation are presented. In particular, we outline solutions for linking automated image processing for personalized oncology with high-performance computing. Finally, we demonstrate the advantages of our proposal, using image data from heterogeneous practical experiments and challenges.

Las orugas del género Lonomia, del orden Lepidoptera y familia Saturnidae, son de interés médico en Sudamérica por ser causantes del lonomismo, tipo de envenenamiento que aumenta cada vez más en Colombia, con tasas de mortalidad de 2,5 %. La severidad es variable y los casos no son de notificación obligatoria, lo que lleva a un subregistro de estos eventos. Se presenta el caso de una mujer adulta joven, quien acude a urgencias por la picadura de 20 orugas Lonomia en la palma de la mano izquierda; presentó signos locales inflamatorios, dolor y limitación de la movilidad de la mano. Se hospitalizó por tres días, se clasificó como leve y se trató con analgesia y antihistamínico endovenoso, lo que logró favorable evolución. El envenenamiento por oruga Lonomia es una urgencia que puede ser mortal, por tanto, es importante que se conozcan estos eventos en la literatura para su adecuado abordaje.
Caterpillars of the genus Lonomia, of the order Lepidoptera, family Saturnidae are of medical interest in South America for being the cause of lonomism, poisoning that is increasing more and more in Colombia, with mortality rates of 2.5%, the severity is variable and they are not mandatory notification, which leads to an underreporting of these events. We present the case of a young adult woman, who went to the emergency room due to the bite of 20 Lonomia caterpillars in the palm of her left hand, generating local inflammatory signs, pain and limitation of hand mobility. She was hospitalized for 3 days, classified as mild and treated with analgesia and intravenous antihistamine; which achieved favorable evolution. Therefore, it was concluded that Lonomia caterpillar poisoning is an emergency, which can be fatal. It is important that these events are known in the literature for their proper approach.

BACKGROUND: Postoperative complications after colorectal cancer surgery have been associated with poor long-term prognosis. The aim of the present study was to investigate the prognostic impact of postoperative complications after colorectal cancer surgery assessed by the Comprehensive Complication Index (CCI®) and designing a new prognostic score based on this index. METHODS: This observational longitudinal study included a series of 604 patients who underwent colorectal surgery for cancer. Demographic data, comorbidity measured by Charlson Index, tumor characteristics, surgical data and postoperative complications were recorded as predictors. Univariate and multivariate analysis were performed and long-term survival was the output variable. Based on Hazard Ratios obtained on multivariate analysis, a new score, S-CRC-PC, was created for predicting long-term survival. RESULTS: Two-hundred and twelve (35.1%) patients developed some postoperative complication. The mean CCI was 11.6 (±19.19). Mild complications (CCI <26.2) were detected in 95 (15.7%) patients. Moderate complications (CCI 26.2-42.2) were detected in 64 (10.6%) patients. Severe complications (CCI >42.3) were detected in 53 patients (8.8%) patients. Mortality rate was 1.7%. In multivariate analysis, age (p < 0.001), Charlson score (p = 0.014), CCI (p < 0.001), and TNM stage (p < 0.001) were statistically significantly in relation to long-term survival rate. S-CRC-PC score was statistically associated with survival rate (HR: 1.34-95% CI: 1.27-1.41). Patients with S-CRC-PC values from 0 to 8 points (low risk), 8.1-16 points (medium risk), and scores above 16 points (high risk) had a cumulative survival rate at five-years of 98%, 83%, and 31% respectively. CONCLUSIONS: Postoperative complications after colorectal cancer surgery assessed by CCI are an independent prognostic factor of survival rate. The S-CRC-PC score may be helpful in predicting long-term cancer outcomes.

This retrospective study aimed to provide some clinical outcomes regarding effectiveness, toxicity, and quality of life in PCa patients treated with dose-escalated moderately hypofractionated radiation therapy (HFRT). Patients received HFRT to a total dose of 66 Gy in 22 fractions (3 Gy/fraction) delivered via volume modulated arc therapy (VMAT) in 2011-2016. Treatment effectiveness was measured by the biochemical failure-free survival rate. Toxicity was assessed according to the criteria of the Radiation Therapy Oncology Group (RTOG) and quality of life according to the criteria of the European Organization for Research and Treatment of Cancer (EORTC). In this regard, quality of life (QoL) was measured longitudinally, at a median of 2 and 5 years after RT. Enrolled patients had low-risk (40.2%), intermediate-risk (47.5%), and high-risk (12.3%) PCa. Median follow-up was 75 months. The biochemical failure-free survival rate was 94.2%. The incidence of acute grade 2 or higher gastrointestinal (GI) and genitourinary (GU) toxicity was 9.84% and 28.69%, respectively. The incidence rate of late grade 2 or higher GI and GU toxicity was 1.64% and 4.10%, respectively. Expanded Prostate Cancer Index Composite (EPIC) scores showed that the majority of patients maintained their QoL. HFRT to 66 Gy with VMAT was associated with adequate biochemical control, low toxicity and good reported GU and GI quality of life.
RESUMO
BACKGROUND: Despite the acceptance of the laparoscopic approach for the treatment of perforated peptic ulcers, its definitive implantation is still a matter of discussion. We performed a comparative study between the open and laparoscopic approach focused on postoperative surgical complications. METHODS: Retrospective observational study in which patients operated on for perforated peptic ulcus in our center between 2001 and 2017 were analyzed. Only those in whom suture and/or omentoplasty had been performed were selected, either for open or laparoscopic approach. Demographic, clinical, and intraoperative variables, complications, mortality and length of stay were collected. Both groups, open and laparoscopic surgery patients, were compared. RESULTS: The final study sample was 250 patients, 190 (76%) men and 60 (24%) women, mean age 54 years (SD ± 16.7). In 129 cases (52%), the surgical approach was open, and in 121 (48%) it was laparoscopic. Grades III-V complications of the Clavien-Dindo Classification occurred in 23 cases (9%). Operative mortality was 1.2% (3 patients). Laparoscopically operated patients had significantly fewer complications (p = 0.001) and shorter hospital stay (p < 0.001). In multivariate analysis, laparoscopic approach (p = 0.025; OR:0.45-95%CI: 0.22-0.91), age (p = 0.003; OR:1.03-95%CI: 1.01-1.06), and Boey score (p = 0.024 - OR:1.71 - CI95%: 1.07-2.72), were independent prognostic factors for postoperative surgical complications. CONCLUSION: Laparoscopic surgery should be considered the first-choice approach for patients with perforated peptic ulcer. It is significantly associated with fewer postoperative complications and a shorter hospital stay than the open approach.

In relation to the article "A case of mixed adenoneuroendocrine tumor of the colon", we would like to contribute a new case of this exceptional and biphasic clinical entity - the MANEC (mixed adenoneuroendocrine carcinoma). These tumors represent a mix of pathological components, are highly aggressive, and affect the gastrointestinal and pancreatobiliary tract. They are characterized by the dual presence of glandular and neuroendocrine epithelial elements, where each component represents at least 30 % of the tumor.

BACKGROUND: Frailty has been shown to be a good predictor of post-operative complications and death in patients undergoing gastrointestinal surgery. The aim of this study was to analyze the differences between frail and non-frail patients undergoing colorectal cancer surgery, as well as the impact of frailty on long-term survival in these patients. METHODS: A cohort of 149 patients aged 70 years and older who underwent elective surgery for colorectal cancer was followed-up for at least 5 years. The sample was divided into two groups: frail and non-frail patients. The Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS) was used to detect frailty. The two groups were compared with regard to demographic data, comorbidities, functional and cognitive statuses, surgical risk, surgical variables, tumor extent, and post-operative outcomes, which were mortality at 30 days, 90 days, and 1 year after the procedure. Univariate and multivariate analyses were also performed to determine which of the predictive variables were related to 5-year survival. RESULTS: Out of the 149 patients, 96 (64.4%) were men and 53 (35.6%) were women, with a median age of 75 years (IQR 72-80). According to the CSHA-CFS scale, 59 (39.6%) patients were frail, and 90 (60.4%) patients were not frail. Frail patients were significantly older and had more impaired cognitive status, worse functional status, more comorbidities, more operative mortality, and more serious complications than non-frail patients. Comorbidities, as measured by the Charlson Comorbidity Index (p = 0.001); the Lawton-Brody Index (p = 0.011); failure to perform an anastomosis (p = 0.024); nodal involvement (p = 0.005); distant metastases (p < 0.001); high TNM stage (p = 0.004); and anastomosis dehiscence (p = 0.013) were significant univariate predictors of a poor prognosis on univariate analysis. Multivariate analysis of long-term survival, with adjustment for age, frailty, comorbidities and TNM stage, showed that comorbidities (p = 0.002; HR 1.30; 95% CI 1.10-1.54) and TNM stage (p = 0.014; HR 2.06; 95% CI 1.16-3.67) were the only independent risk factors for survival at 5 years. CONCLUSIONS: Frailty is associated with poor short-term post-operative outcomes, but it does not seem to affect long-term survival in older patients with colorectal cancer. Instead, comorbidities and tumor stage are good predictors of long-term survival.

Thyroid cancer represents a heterogenous disease whose incidence has increased in the last decades. Although three main different subtypes have been described, molecular characterization is progressively being included in the diagnostic and therapeutic algorithm of these patients. In fact, thyroid cancer is a landmark in the oncological approach to solid tumors as it harbors key genetic alterations driving tumor progression that have been demonstrated to be potential actionable targets. Within this promising and rapid changing scenario, current efforts are directed to improve tumor characterization for an accurate guidance in the therapeutic management. In this sense, it is strongly recommended to perform tissue genotyping to patients that are going to be considered for systemic therapy in order to select the adequate treatment, according to recent clinical trials data. Overall, the aim of this article is to provide a comprehensive review on the molecular biology of thyroid cancer focusing on the key role of tyrosine kinases. Additionally, from a clinical point of view, we provide a thorough perspective, current and future, in the treatment landscape of this tumor.

BACKGROUND: Advanced age is a risk factor for colorectal cancer, and very elderly patients often need to be surgically treated. This study aimed to analyze the outcomes of a cohort of nonagenarian patients operated on for colorectal cancer. METHODS: Observational study conducted on a cohort of 40 nonagenarian patients, who were treated surgically for colorectal cancer between 2000 and 2018 in our institution. Clinical data, ASA score, Charlson Comorbidity Index, Surgical Mortality Probability Model, tumor characteristics, and nature and technical features of the surgical procedure, were recorded. The Comprehensive Complication Index (CCI) and survival time after the procedure were recorded as outcome variables. Univariate and multivariate analyses were performed in order to define risk factors for postoperative complications and long-term survival. RESULTS: Out of the 40 patients, 13 (32.5%) were men, 27 (67.5%) women, and mean age 91.6 years (SD ± 1.5). In 24 patients (60%), surgery was elective, and in 16 patients (40%), surgery was emergent. Curative surgery with intestinal resection was performed in 34 patients (85%). In 22 patients (55%), intestinal continuity was restored by performing an anastomosis. The median CCI was 22.6 (IRQ 0.0-42.6). Operative mortality was 10% (4 patients). Cumulative survival at 1, 3, and 5 years was 70%, 47%, and 29%, respectively. In multivariate analysis, only the need for transfusion remained as an independent prognostic factor for complications (p = 0.021) and TNM tumor stage as a significant predictor of survival (HR 3.0, CI95% 1.3-7.2). CONCLUSIONS: Colorectal cancer surgery is relatively safe in selected nonagenarian patients and may achieve long-term survival.

PURPOSE: Preoperative assessment at extreme ages would identify patients at a high risk of developing postoperative complications. The objective of this study was to compare the usefulness of different risk scales in a series of nonagenarian surgical patients. METHODS: A total of 244 surgical nonagenarians, 148 women (60.7%), median age 91 years (IQR: 90-93), were analysed. The following scales were evaluated: preoperative status (ASA-PS, Charlson Comorbidity Index, Lee Index, Reiss Index, and surgical mortality probability model-S-MPM); intraoperative status (Surgical Apgar Score and SASA score), and, as output variables, surgical outcomes (morbidity measured by the Comprehensive Complication Index-CCI, and death). Univariate analysis and receiver operating characteristic curves (ROC) were performed. Area under ROC curves (AUROC) were evaluated to define the best predictors of poor outcomes. RESULTS: Operative mortality was 27.0%, and 73.4% presented some type of postoperative complication. Operative mortality was associated with the ASA-PS score (p < 0.001), Reiss Index (p < 0.001), Lee Index (p = 0.010), S-MPM (p < 0.001), Surgical Apgar Score (p < 0.001), SASA score (p < 0.001), and emergency surgery (p < 0.001). Postoperative complications were related to the ASA-PS score (p = 0.001), Reiss Index (p < 0.001), Lee Index (p < 0.001), S-MPM (p < 0.001), Surgical Apgar Score (p < 0.001) and SASA score (p < 0.001). The best predictors of operative mortality and complications were the SASA and Surgical Apgar Score (AUROCs > 0.88). CONCLUSION: As in the general population, the Surgical Apgar Score and SASA score are the best predictors of operative mortality and morbidity in nonagenarian patients. These risk scales should be considered in the perioperative management of these patients.

Lymphomas are a large, heterogeneous group of neoplasms with well-defined characteristics, and this heterogeneity highlights the importance of epidemiological data. Knowledge of local epidemiology is essential to optimise resources, design clinical trials, and identify minority entities. Given there are few published epidemiological data on lymphoma in Spain, the Spanish Lymphoma and Autologous Bone Marrow Transplant Group created the RELINF project. The aim of this project is to determine the frequencies and distribution of lymphoid neoplasms in Spain and to analyse survival. We developed an online platform for the prospective collection of data on newly diagnosed cases of lymphoma in Spain between January 2014 and July 2018; 11,400 patients were registered. Diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL) were the most frequent lymphomas in our series. Marginal B cell lymphoma frequency was higher than that reported in other studies, representing more than 11% of mature B cell lymphomas. Peripheral T cell lymphoma not otherwise specified (PTCL-NOS) was the most common subtype of T cell lymphoma, and NK/T cell lymphomas were more frequent than expected (5.4% of total). Hodgkin's lymphoma accounted for 12% of lymphoproliferative syndromes. Overall survival was greater than 90% at 2 years for indolent B cell lymphomas, and approximately 60% for DLBCL, somewhat lower than that previously reported. Survival was poor for PTCL-NOS and angioimmunoblastic T cell lymphoma, as expected; however, it was somewhat better than that in other studies for anaplastic large cell anaplastic lymphoma kinase lymphomas. This is the first prospective registry to report the frequencies, distribution, and survival of lymphomas in Spain. The frequencies and survival data we report here are globally consistent with that reported in other Western countries. These updated frequencies and survival statistics are necessary for developing appropriate management strategies for neoplasias in the Spanish population.

BACKGROUND: Despite increases in knowledge and advances in the management of acute mesenteric ischemia syndrome (AMI), there have been no significant improvements in mortality in recent years. The objective of this study was to assess the changes in clinical characteristics and surgical outcomes in patients who underwent AMI over time. METHODS: A total of 323 consecutive patients who underwent acute mesenteric ischemia at our institution between 1990 and 2015 were examined. The occurrence of significant changes over this 25-year period in demographic data, comorbidity, clinical characteristics, laboratory results, operative findings, etiology of the AMI, and operative mortality were evaluated. The evolution mortality rates for the studied period were analyzed using the additive logistic regression, and the significant effect was determined using the Akaike Information Criterion (AIC). RESULTS: A significant increasing linear trend was observed in recent years in Charlson score values (p = 0.008), antiplatelet drug intake (p < 0.001), use of CT scan (p < 0.001), arterial thrombosis (p < 0.001), and intestinal resection (p = 0.047), while a decreasing linear trend was observed in digoxin intake (p < 0.001), angiography use (p = 0.004), and embolia (p < 0.001). The rest of the parameters did not present changes over time. Regarding the evolution of the adjusted surgical mortality, a significant decrease according the AIC criterion was observed. CONCLUSIONS: In recent years, the characteristics of patients with AMI requiring surgery have changed. Changes in operative mortality have also been detected, showing a tendency toward a progressive and significant decrease.

BACKGROUND: Frailty has been proposed as an independent risk factor for predicting postsurgical outcomes in elderly surgical patients. The Comprehensive Complication Index (CCI) seems to be the most widely used grading of individual complications in many surgical fields. The objective of this study was to evaluate the association of frailty, measured by Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS), with the CCI in the elderly surgical patient. MATERIAL AND METHODS: A prospective cross-sectional study was carried out in 256 patients aged ≥70 y who underwent major gastrointestinal surgery. Sociodemographic characteristics, baseline disease, CSHA-CFS, and medical/surgical complication using the Comprehensive Comorbidity Index were evaluated. We hypothesized that frailty measured by CSHA-CFS and the CCI are associated. RESULTS: Of 256 patients, 154 (60%) were men and 102 (40%) were women, with mean age of 76.1 y (SD ± 5.1). One-hundred and eighty-five patients (74%) underwent surgery for a malignant cause, and 97 patients (38%) had some degree of frailty. Mean CCI was 16.1 (SD ± 23.0). Postoperative mortality was 3%. Pondering the scale CCI 0-100, frailty correlated well with postoperative complications (P = 0.035). For patients who developed at least 1 complication, for each unit that the CSHA-CFS was raised, the CCI increased by 5.2 points (P = 0.002). The multivariate analysis showed that the CSHA-CFS was the only independent prognostic factor associated with postoperative CCI in this series. CONCLUSIONS: Frailty determined by CSHA-CFS is closely associated with the CCI, being a good predictor of postoperative complications in the elderly patient operated on by a major gastrointestinal procedure.

AIM: The number of nonagenarians undergoing surgery has increased considerably in recent decades as a result of population aging. Greater knowledge of the most influential factors affecting perioperative morbidity and mortality would improve the quality of care and provision of health resources for these patients. The objective of the present study was to analyze the perioperative mortality, and its most determinant factors, among nonagenarian patients who underwent a surgical procedure in the Department of General and Digestive Surgery. METHODS: A retrospective descriptive study was carried out in a cohort of 159 consecutive non-selected surgical nonagenarian patients. Clinical data, type of operation, perioperative hemodynamic instability, the need for blood transfusion and medical/surgical complications were evaluated as predictor variables. The outcome variable was operative mortality. RESULTS: The mean age was 91.8 years (SD ± 2.0); there were 60 men (37.7%) and 99 (62.3%) women. Perioperative mortality was 28.93% (46 patients). The variables age (P = 0.025), American Society of Anesthesiologists physical status score (P < 0.001), neoplastic pathology (P = 0.025), intestinal surgery (P = 0.001), emergent surgery (P ≤ 0.001), perioperative blood transfusion (P = 0.003), postoperative medical complications (P < 0.001) and surgical complications (P = 0.022) showed a statistically significant correlation with mortality. American Society of Anesthesiologists physical status score (P = 0.007), emergent surgery (P < 0.032) and perioperative blood transfusion (P = 0.047) were identified as independent predictors of mortality. CONCLUSIONS: Surgery should not be denied to nonagenarian patients based only on their age. Emergency surgery and American Society of Anesthesiologists physical status classification are the most significant factors when deciding whether to intervene. Geriatr Gerontol Int 2019; 19: 293-298.

INTRODUCTION: The main step in curative treatment for breast cancer is surgery. Its use in an ambulatory setting can contribute towards more efficient healthcare, providing additional benefits for patients. In this study, we analyze the results obtained with this treatment method and identify factors related with conversion to hospitalization. METHODS: Results were analyzed from the 206 surgeries performed for breast cancer in 2016, using three different methods: day surgery, overnight ambulatory (23h) and conventional hospitalization. The ambulatory success and conversion rates were calculated for the global sample and stratified, distinguishing between conservative surgery, mastectomy and axillary surgery. A univariate analysis was performed to identify the factors involved in conversion. RESULTS: For the global sample, the ambulatory surgery rate was 61.2%, 16.5% conversions and a success rate of 83.4%. For conservative surgery, ambulatory, success and conversion rates were 78.8%, 88.6 and 11.4%, respectively. For mastectomies, the ambulatory rate was 28.6%, with 62.9% success and 37.1% conversions. The 11 axillary surgeries were performed as day surgeries. Factors associated with conversion were mastectomy vs. vs. conservative surgery and the appearance of postoperative complications. CONCLUSIONS: Ambulatory surgery for the surgical treatment of breast cancer should be standard care. Optimized results require adequate patient selection and the performance of surgical technique that needs to be as careful and as conservative as possible.
