BACKGROUND Merkel cell polyomavirus (MCPyV) is associated with the development of Merkel cell carcinoma (MCC). Antibody (MCPyV-Ab) titers may have prognostic implications. This study evaluated the impact of the presence or absence of MCPyV-Ab on the 2-year overall survival (OS) and disease-free survival (DFS) of MCC patients. METHODS This single-center, IRB-approved, retrospective cohort study evaluated 51 adult patients with MCC from 2014 to 2021 using a prospectively maintained database. Patients were compared by MCPyV-Ab status, and Kaplan-Meier analysis was used to evaluate 2-year OS and DFS. RESULTS Of the 51 patients, 13 (25.4%) were seropositive, 41 (80.4%) underwent wide excision, 40 (80.0%) received radiotherapy, and 43 (84.3%) received multimodal therapy. The median follow-up period was 15.5 months (range 1-69.5 months). The median 2-year OS of the entire cohort was not reached. The median 2-year OS was not reached for either the seronegative or the seropositive patients. The difference in 2-year OS between the groups was not statistically significant (p = 0.37). Eight patients, all seronegative, were never rendered disease-free and were removed from recurrence analysis. The seropositive patients experienced no recurrences. Of the 30 seronegative patients, 9 (30.0%) experienced recurrence. The median 2-year DFS of the entire cohort was not reached. The median 2-year DFS of the seronegative group was 22.2 months. The 2-year DFS was not reached for the seropositive cohort. Seropositivity conferred a significantly better 2-year DFS than seronegativity (p = 0.04). CONCLUSION The MCPyV-Ab seropositive patients demonstrated improved 2-year DFS. The seropositive patients showed a strong trend toward improved 2-year OS, although the difference not statistically significant. This study substantiated the value of MCPyV-Ab assessment for MCC.

Appendiceal neoplasms are uncommon tumors. Optimal treatment for patients with perforation or high-grade pathology after initial resection is unknown. This study evaluated patients with increased risk for peritoneal dissemination after primary resection, but no evidence of peritoneal disease, who underwent adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC). This multi-institutional cohort study evaluated 56 patients with high-risk (HR) appendiceal neoplasms with a peritoneal carcinomatosis index of 0 who underwent HIPEC. The patients were divided into two groups: perforated low-grade appendiceal (LGA) carcinoma and HR neoplasms, which included perforated high-grade appendiceal carcinoma, positive margins after initial resection, minimal macroscopic peritoneal disease that was previously resected or completely responded to systemic chemotherapy prior to HIPEC, goblet cell carcinoma, and adenocarcinoma with signet ring cell features. Overall survival (OS) and recurrence-free survival (RFS) were estimated by Kaplan–Meier analysis. Thirty-eight percent of patients had perforated LGA and 68% had HR features. Five-year OS probability was 82.1% for the entire cohort, and 100% and 70.1% for patients with perforated LGA and HR features, respectively (p = 0.024). Five-year RFS probability was 79.3% for the entire cohort, and 90.0% and 72.4% for patients with perforated LGA and HR features, respectively (p = 0.025). Eight patients recurred after HIPEC and their OS was significantly worse (p

Care of pancreatic cancer patients has become increasingly complex, which has led to delays in the initiation of therapy. Nurse navigators have been added to care teams, in part, to ameliorate this delay. This study investigated the difference in time from first oncology visit to first treatment date in patients with any pancreatic malignancy before and after the addition of an Oncology Navigator. A single-institution database of patients with any pancreatic neoplasm evaluated by a provider in radiation, medical, or surgical oncology between 1 October 2015 and 30 September 2017 was analyzed. After 1 October 2016, an Oncology Navigator met patients at their initial visit and coordinated care throughout treatment. The cohort was divided into two groups: patients evaluated prior to the implementation of an Oncology Navigator and patients evaluated after implementation. Patient demographics and time from first visit to first intervention were compared. Overall, 147 patients with a new diagnosis of pancreatic neoplasm were evaluated; 57 patients were seen prior to the start of the Oncology Navigator program and 79 were evaluated after the navigation program was implemented. On univariate analysis, time from first contact by any provider to intervention was 46 days prior to oncology navigation and 26 days after implementation of oncology navigation (p = 0.005). While controlling for other covariates, employment of the Oncology Navigator decreased the time from first contact by any provider to intervention by almost 16 days (p = 0.009). Implementing an oncology navigation program significantly decreased time to treatment in patients with pancreatic malignancy.
