Return to intended oncologic treatment (RIOT): a novel metric for evaluating the quality of oncosurgical therapy for malignancy.

چکیده
BACKGROUND After cancer surgery, complications, and disability prevent some patients from receiving subsequent treatments. Given that an inability to complete all intended cancer therapies might negate the oncologic benefits of surgical therapy, strategies to improve return to intended oncologic treatment (RIOT), including minimally invasive surgery (MIS), are being investigated. METHODS This project was designed to evaluate liver tumor patients to determine the RIOT rate, risk factors for inability to RIOT, and its impact on survivals. Outcomes for a homogenous cohort of 223 patients who underwent open-approach surgery for metachronous colorectal liver metastases and a group of 27 liver tumor patients treated with MIS hepatectomy were examined. RESULTS Of the 223 open-approach patients, 167 were offered postoperative therapy, yielding a RIOT rate of 75%. The remaining 56 (25%) patients were unable to receive further treatment due to surgical complications (n = 29 pts) or poor performance status (n = 27 pts). Risk factors associated with inability to RIOT were hypertension (OR 2.2, P = 0.025), multiple preoperative chemotherapy regimens (OR 5.9, P = 0.039), and postoperative complications (OR 2.0, P = 0.039). Inability to RIOT correlated with shorter disease-free and overall survivals (P < 0.001, HR = 2.16; and P = 0.005, HR = 2.07, respectively). In contrast to the open surgery group, 100% of MIS patients who were intended to initiate postoperative therapy did so (P = 0.038) within a shorter median time interval (MIS: 15 days vs. open: 42 days; P < 0.001). CONCLUSIONS The relationship between RIOT and long-term oncologic outcomes suggests that RIOT rates for both open- and MIS-approach cancer surgery should routinely be reported as a quality indicator.

متن کاملReduced-Reference Image Quality Assessment based on saliency region extraction
In this paper, a novel saliency theory based RR-IQA metric is introduced. As the human visual system is sensitive to the salient region, evaluating the image quality based on the salient region could increase the accuracy of the algorithm. In order to extract the salient regions, we use blob decomposition (BD) tool as a texture component descriptor. A new method for blob decomposition is propos...

Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...
