Análisis de supervivencia e identificación de factores pronósticos de metástasis hepáticas de cáncer colorrectal tras resección hepática

IntroductionLiver resection is the only curative treatment for colorectal liver metastasis. The identification of predictive factors leads to personalize patient management to enhance their long-term outcomes. This population-based study aimed to characterize factors associated with, and survival impact of patients who received hepatectomy for colorectal liver metastasis.MethodsA retrospective cohort study of all the hepatectomies for colorectal liver metastasis performed at third-level hospital of Spain (2010–2018) was conducted. The Kaplan–Meier method was used for survival analyses. Multivariable Cox and regression models were used to determine prognostic factors associated with overall survival.ResultsThe 5-year overall survival and disease-free survival were 42 and 33%, respectively. Survival analysis showed that metastasis features (number, largest size, distribution, and extrahepatic disease) and postsurgical factors (transfusion, major complications, and positive margin resection), as well as non-mutated KRAS, showed a significant association with survival. Otherwise, on multivariate analysis, only 5 independent risk factors were identified: major size metastasis > 4 cm, RAS mutation, positive margin resection, intraoperative transfusion, and major complications.ConclusionsAccording to our findings, major size metastasis > 4 cm, intraoperative transfusion, and major postoperative complications continue to be traditional prognostic factors. Meanwhile, the KRAS biomarker has a powerful impact as a survival prognostic factor.     

Tratamiento de las complicaciones hemorrágicas de la nefrolitotomía percutánea en posición de Galdakao

ObjetivePercutaneous Nephrolithotomy (PCNL) is a technique with good results for the treatment of kidney stones, however, bleeding complications derived can be serious if not diagnosed and treated effectively. The aim of this study is to assess bleeding complications resulting from PCNL in Galdakao position and therapeutic management.Material and methodsRetrospective-longitudinal study of 172 PCNL performed in La Ribera Hospital between January 2005 and December 2011, analyzing their bleeding complications and the treatment provided for resolution.ResultsHad bleeding complications 20 patients (11.6%). The need for transfusion in this series was 8.1% and the most common cause of blood transfusion the presence of postoperative retroperitoneal (7.5%). There were 6 arterial injuries (3.5%), 5 of them successfully treated with angiography and arterial selective embolization.ConclusionsThe arterial injuries following PCNL are rare but can be serious. The possibility of an urgent arteriography and selective embolization to the diagnosis permits an effective and safe treatment of bleeding without risk to the affected renal unit.     

Metástasis gastrointestinales de carcinoma pulmonar primario. Serie de casos y revisión sistemática de la literatura

Aim of the present study is to report clinical characteristics and outcomes of patients treated in authors’ hospital for GI metastasis from primary lung cancer, and to report and analyse the same data concerning patients retrieved from a systematic literature review.We performed a retrospective analysis of prospectively collected data, and a systematic review using the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines.Ninety-one patients were included, 5 patients from the authors’ hospital and 86 through PubMed database using the keywords “intestinal metastasis” AND “lung cancer”. The median time between primary lung cancer diagnosis and GI metastasis diagnosis was 2 months and the median overall survival was 4 months.This group of patients present a poor prognosis and the gold standard treatment is not defined. None of the reported treatments had a significant impact on survival.     

Cirugía de las metástasis en la glándula suprarrenal: resultados de una serie de 35 pacientes

IntroductionThe objectives of this study are to present the results of adrenalectomies due to metastasis, and to analyse the prognostic factors that may help to predict long-term survival in this patient group.Patients and methodsA retrospective study was conducted on 35 patients who underwent adrenalectomy for metastases in the Hospital de Cruces from 1996 to January 2010. The survival analysis was performed using the Kaplan and Meier method.ResultsNon-small cell lung cancer (NSCLC) was the most frequent primary tumour, with 18 cases. In 15 patients the diagnosis of adrenal metastasis was synchronous with the primary tumour, and in 20 cases it was metachronous. Only 7 patients survived without disease for 12, 22, 26, 58, 60, 65 and 120 months after the adrenalectomy. The disease free survival at 5 years was 16% in the whole series, and 27% in the NSCLC sub-group. None of the prognostic factors evaluated (size greater than 4.5 cm, cell type, differentiation grade, chemotherapy, surgical technique, disease free interval) was statistically significant in the overall survival, either in the general series or in the sub-group of patients with NSCLC. However, in the general series with tumour recurrence, the difference in survival between metachronous and synchronous metastasis was statistically significant (P=.05), in favour of the former.ConclusionsAdrenalectomy improves the expected survival particularly in patients with NSCLC. Patients with metachronous metastases do not have a higher rate of disease free survival at 5 years than those with synchronous metastases, although they do have a longer survival with the disease. When there is tumour recurrence, it is usually early.

Predicción de resultados de cistoscopias en la práctica

ObjectiveOur objective was to elaborate a predictive model of bladder cancer, in an unselected clinical population submitted to cystoscopy.Materials and methodsWe recruited consecutive patients that underwent cystoscopy due to suspicion of bladder cancer or surveillance of a previously diagnosed bladder cancer. Urine cytology and a BTA-stat® (BTA) test were carried out for all patients. To avoid an assessment bias, the BTA-tests, cytologies and cystoscopies were conducted in a blinded fashion. We used logistic regression to predict cystoscopy results from cytology, BTA-test and clinical variables.ResultsFrom August 2011 to July 2012, we recruited 244 patients and 237 were valid for analysis. Newly diagnosed and surveillance cases were 13% and 87% respectively. Cytology and BTA-test sensitivities were 57.9% (CI 95: 42.2-72.1) and 63.2% (CI 95: 47.3-76.6) with specificities of 84.4% (CI 95: 78.7-88.8) and 82.9% (CI 95: 77.1-87.5). The predictive model included the BTA-test, cytology, time since previous tumour, and treatment with mitomicin or BGC during the last three months. The model predictive accuracy (AUC) was .85 (.78-.92), and dropped to 0.79 when excluding the BTA-test (P = .026). For the surveillance of bladder cancer, a 10% threshold on the model predicted probabilities resulted in an overall negative predictive value of 95.7%, and 95.0% in low grade tumours.ConclusionIn a cost containment environment, our prediction model could be used to space out cystoscopies in patients with previous, low grade tumours, resulting in a more efficient use of resources in the healthcare system.     

Correção endovascular de lesão de artéria subclávia secundária à cateterismo de veia jugular interna: relato de caso

Background and objectivesUltrasound‐guided internal jugular vein catheterization is a common and generally safe procedure in the operating room. However, inadvertent puncture of a noncompressible artery such as the subclavian artery, though rare, may be associated with life‐threatening sequelae, including hemomediastinum, hemothorax, and pseudoaneurysm.Case reportWe describe a case of the successful endovascular repair of right subclavian artery injury in a 75‐year‐old woman. Subclavian artery was injured secondary to ultrasound‐guided right internal jugular vein catheterization under general anesthesia for orthopedic surgery.ConclusionUnder general anesthesia several factors such as hypotension can mask the signs of subclavian artery injury. This case report indicates that clinicians should be aware of the complications of central venous catheterization and take prompt action.     

Resultados obtenidos tras el tratamiento quirúrgico de los pacientes con metástasis hepáticas de sarcomas

IntroductionThe presence of liver metastases in sarcomatous tumors is associated with poor prognosis. However, in selected patients, surgical resection has been suggested as a tool to improve survival rates. The aim of our study is to describe postoperative and oncological outcomes after liver resection.MethodsA retrospective unicentric study was conducted including patients diagnosed with hepatic metastases from soft tissue sarcoma who underwent hepatic resection between 2003 and 2019. The inclusion criteria were the presence of resectable disease, including synchronic and metachronic lesions. The presence of extra-hepatic controlled disease was not considered unresectable.ResultsNineteen patients underwent liver resection for liver metastasis of 7 different sarcomatous subtypes. Median age was 58-yo. Liver metastases were diagnosed a median 25 months after primary tumor diagnosis. Six patients (32%) suffered of synchronic metastases and 12 (63%) were affected of extrahepatic disease. Major hepatectomy was done in 5 (26%) patients, 8 (42%) minor complications were described. Median follow-up was 33 months. Survival analysis was performed independently for, GIST tumors and non-GIST sarcomas. One, three and five-year survival rate was 100%, 85.7% and 42.9% in non-GIST sarcomas, while five and ten-year survival rate was 100% and 40% in GIST, respectively.ConclusionsSurgical approach of liver metastases of sarcomatous tumors seems to be useful in order to improve survival in selected patients, while associated to be of low complications rate. In our cohort, extrahepatic disease rate is high in comparison with series published before, nevertheless survival is comparable. These results support performing surgical resection in selected patients with stable extrahepatic disease.

Dosis reducida vs. dosis completa de BCG en el cáncer de vejiga: revisión sistemática y metaanálisis

ObjectiveTo assess the oncologic outcomes and the safety profile of a reduced-dose versus full-dose BCG regimen in patients with non-muscle-invasive bladder cancer (NMIBC).Material and MethodsWe performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The PubMed, Embase, and Web of Science databases were searched in January 2022 for studies that analyzed oncological outcomes and compared between reduced- and full-dose BCG regimens.ResultsSeventeen studies including 3757 patients met our inclusion criteria. Patients who received reduced-dose BCG had significantly higher recurrence rates (OR 1.19; 95%CI, 1.03-1.36; p = 0.02). The risks of progression to muscle-invasive BC (OR 1.04; 95%CI, 0.83-1.32; p = 0.71), metastasis (OR 0.82; 95%CI, 0.55-1.22; p = 0.32), death from BC (OR 0.80; 95%CI, 0.57-1.14; p = 0.22), and all-cause death (OR 0.82; 95%CI, 0.53-1.27; p = 0.37) were not statistically different. When restricting the analyses to randomized controlled trials, we found similar results. In subgroup analysis, reduced dose was associated with a higher rate of BC recurrence in studies that used only an induction regimen (OR 1.70; 95%CI, 1.19-2.42; p = 0.004), but not when a maintenance regimen was used (OR 1.07; 95%CI, 0.96-1.29; p = 0.17). Regarding side effects, the reduced-dose BCG regimen was associated with fewer episodes of fever (p = 0.003), and therapy discontinuation (p = 0.03).ConclusionThis review found no association between BCG dose and BC progression, metastasis, and mortality. There was an association between reduced dose and BC recurrence, which was no longer significant when a maintenance regimen was used. In times of BCG shortage, reduced-dose regimens could be offered to BC patients.
