Background: Patients with cancer are at high risk for having mental disorders, resulting in widespread psychosocial screening efforts. However, there is a need for population-based and longitudinal studies of mental disorders among patients who have gastrointestinal cancer and particular among elderly patients. Patients and Methods: We used the SEER-Medicare database to identify patients aged ≥65 years with colorectal, pancreatic, gastric, hepatic/biliary, esophageal, or anal cancer. Earlier (12 months before or up to 6 months after cancer diagnosis) and subsequent mental disorder diagnoses were identified. Results: Of 112,283 patients, prevalence of an earlier mental disorder was 21%, 23%, 20%, 20%, 19%, and 26% for colorectal, pancreatic, gastric, hepatic/biliary, esophageal, and anal cancer, respectively. An increased odds of an earlier mental disorder was associated with pancreatic cancer (odds ratio [OR], 1.17; 95% CI, 1.11–1.23), esophageal cancer (OR, 1.10; 95% CI, 1.02–1.18), and anal cancer (OR, 1.17; 95% CI, 1.05–1.30) compared with colorectal cancer and with having regional versus local disease (OR, 1.09; 95% CI, 1.06–1.13). The cumulative incidence of a subsequent mental disorder at 5 years was 19%, 16%, 14%, 13%, 12%, and 10% for patients with anal, colorectal, esophageal, gastric, hepatic/biliary, and pancreatic cancer, respectively. There was an association with having regional disease (hazard ratio [HR], 1.08; 95% CI, 1.04–1.12) or distant disease (HR, 1.36; 95% CI, 1.28–1.45) compared with local disease and the development of a mental disorder. Although the development of a subsequent mental disorder was more common among patients with advanced cancers, there continued to be a significant number of patients with earlier-stage disease at risk. Conclusions: This study suggests a larger role for incorporating psychiatric symptom screening and management throughout oncologic care.

Purpose: We sought to evaluate whether pathologic nodal response was predictive of outcomes in women aged ≤40 years with breast cancer treated with neoadjuvant chemotherapy (NAC). Methods: A total of 220 patients treated with NAC between 1991 and 2015 were retrospectively reviewed. Pathologic complete response (pCR) was defined as no evidence of residual invasive tumor in the breast and lymph nodes (LNs) (ypT0/Tis ypN0); partial response if there was no tumor in the LNs but residual tumor in the breast (ypT+ ypN0) or residual tumor in the LNs (ypT0/Tis ypN+); and limited response if there was residual tumor in both the breast and the LNs (ypT+ ypN+). Kaplan-Meier and Cox proportional hazards analyses were performed to identify factors predictive for overall survival (OS). Results: A total of 155 patients were included. Following NAC, 39 patients (25.2%) achieved pCR, 57 (36.8%) achieved a partial response (either ypT+ ypN0 or ypT0/Tis ypN+), and 59 (38.1%) had a limited response. A total of 22 patients (14.2%) experienced local failure, 20 (12.9%) experienced regional failure, and 59 (38.1%) experienced distant failure. Median OS for patients who achieved pCR was not reached, and was significantly worse for patients who had residual disease in the breast and/or LNs (P<.001). No difference in OS was seen among patients who had residual disease in the breast alone versus those who remained LN-positive (97 vs 83 months, respectively; P=.25). Subset analysis did not reveal differences in OS based on year of treatment or cN1 disease at the time of initial diagnosis. Conclusions: Women aged ≤40 years who achieved pCR had excellent outcomes; however, those who achieved a pathologic response in the LNs but had residual disease in the breast continued to have outcomes similar to those who remained LN-positive.
