Purpose: In patients with colorectal cancer, a high-density local inflammatory infiltrate response is associated with improved survival, whereas elevated systemic inflammatory responses are associated with poor survival. One potential unifying mechanism is the IL6/JAK/STAT3 pathway. The present study examines the relationship between tumor total STAT3 and phosphorylated STAT3Tyr705 (pSTAT3) expression, host inflammatory responses, and survival in patients undergoing resection of stage I–III colorectal cancer.Experimental Design: Immunohistochemical assessment of STAT3/pSTAT3 expression was performed using a tissue microarray and tumor cell expression divided into tertiles using the weighted histoscore. The relationship between STAT3/pSTAT3 expression and local inflammatory (CD3+, CD8+, CD45R0+, FOXP3+ T-cell density, and Klintrup–Mäkinen grade) and systemic inflammatory responses and cancer-specific survival were examined.Results: A total of 196 patients were included in the analysis. Cytoplasmic and nuclear STAT3 expression strongly correlated (r = 0.363; P < 0.001); nuclear STAT3 and pSTAT3 expression weakly correlated (r = 0.130; P = 0.068). Cytoplasmic STAT3 was inversely associated with the density of CD3+ (P = 0.012), CD8+ (P = 0.003), and FOXP3+ T lymphocytes (P = 0.002) within the cancer cell nests and was associated with an elevated systemic inflammatory response as measured by modified Glasgow Prognostic Score (mGPS2: 19% vs. 4%, P = 0.004).The combination of nuclear STAT3/pSTAT3 stratified 5-year survival from 81% to 62% (P = 0.012), however, was not associated with survival independent of venous invasion, tumor perforation, or tumor budding.Conclusions: In patients undergoing colorectal cancer resection, STAT3 expression was associated with adverse host inflammatory responses and reduced survival. Upregulation of tumor STAT3 may be an important mechanism whereby the tumor deregulates local and systemic inflammatory responses. Clin Cancer Res; 23(7); 1698–709. ©2016 AACR.

Objective To design and develop a digital monitoring application to support and improve the care of patients in the first 30 post-operative days following colorectal cancer surgery. Data Sources Patient interviews, health professional focus groups, patient co-creation activities, and health professional prioritization discussions. Conclusion The structured and iterative co-design activities adopted in this study with key stakeholders, including patients and health professionals, lead to the development of a prototype application (app) to support patients at home during the first 30 days following surgery for colorectal cancer. A similar approach could be implemented to develop comparable apps for patients with other cancer diagnoses requiring different surgical procedures. Further research should focus on the continued development and testing of this app in relation to patient care and outcomes as well as the app's affect on nursing and other health services. Implications for Nursing Practice Clinical implementation of remote monitoring following discharge home after surgery for colorectal cancer gives patients the opportunity to report issues of concern to relevant health professionals. This could facilitate the early identification of concerning signs and symptoms, ensuring appropriate and timely interventions to minimize readmission rates. Patients’ experiences during the recovery period could also be improved through the provision of reliable and relevant online information. More specifically, health professionals could easily identify those patients requiring additional support to manage their recovery, for example, those with more severe symptoms or problems, facilitating the direction of appropriate health services to those most in need of their expertise.
