BackgroundThe majority of rectal cancers are discovered in locally advanced forms (UICC stage II, III). Treatment consists of preoperative radiochemotherapy, followed by surgery 6–8 weeks later and finally by postoperative chemotherapy. The aim of this study was to find out if tumor regression affected long-term survival in patients with localy advanced rectal cancer, treated with neoadjuvant radiochemotherapy.Patients and methodsPatients with rectal cancer stage II or III, treated between 2006 and 2010, were included in a retrospective study. Clinical and pathohistologic data were acquired from computer databases and information about survival from Cancer Registry. Survival was estimated according to Kaplan-Meier method. Significance of prognostic factors was evaluated in univariate analysis; comparison was carried out with log-rank test. The multivariate analysis was performed according to the Cox regression model; statistically significant variables from univariate analysis were included.ResultsTwo hundred and two patients met inclusion criteria. Median follow-up was 53.2 months. Stage ypT0N0 (pathologic complete response, pCR) was observed in 14.8% of patients. Pathohistologic stage had statistically significant impact on survival (p = 0.001). 5-year survival in patients with pCR was>90%. Postoperative T and N status were also found to be statistically significant (p = 0.011 for ypT and p < 0.001 for ypN). According to multivariate analysis, tumor response to neoadjuvant therapy was the only independent prognostic factor (p = 0.003).ConclusionsPathologic response of tumor to preoperative radiochemotherapy is an important prognostic factor for prediction of long-term survival of patients with locally advanced rectal cancer.
Ultrasound-guided endovascular treatment of arteriovenous fistula or graft is a feasible and safe method of reestablishing or maintaining a functional vascular access. .
Purpose: Cervical traumas are frequent in emergency department and X-ray, CT, and MRI are the essential imaging modalities in the diagnosis. However, especially for pregnant and morbid obese patients and children, these techniques can be challenging. We tested the success of point-of-care ultrasound in the evaluation of cervical traumas. Methods: This is a case series of cervical vertebra imaging with ultrasound in emergency department. We used linear probe and placed it anterolaterally to the neck, parallel to cervical spine. Images were obtained by an ultrasound-certified emergency physician. The height of the anterior wall of vertebral body, irregularity in vertebral body, and intervertebral space were assessed. Results: We presented a case series of six patients. Ultrasound images of cervical vertebral bodies and intervertebral spaces were able to obtain for all the patients. Any pathology was not observed in ultrasound imaging. This finding was compatible with cervical X-ray and CT scans and all the patients were discharged. Conclusions: However, this is a case series report of minor cervical trauma, and we were able to obtain ultrasound images of cervical vertebra bodies with point-of-care ultrasound examination by an emergency physician. This technique can be important for the patients contraindicated to CT or MRI. Also, it can give additional information to X-ray and CT scans especially for soft tissues. A2 A new technique in verifying the placement of a nasogastric tube: obtaining the longitudinal view of nasogastric tube in addition to transverse view with ultrasound
Chronic renal replacement therapy with hemodialysis and strict uremic, electrolyte, and volume control may be more beneficial for patients with advanced heart failure with preserved or reduced LVEF than ultrafiltration alone. We have observed better survival of terminal cardiorenal patients treated with hemodialysis than in the general NYHA IV population, with lower hospital readmission rate and less hospitalized days for heart failure. .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
