Abstract Background Sexual dysfunction is often complex and biopsychosocial. Traditional sexual health care management involves individual providers not in a multi-disciplinary setting. A multi-disciplinary team may consist of a medical provider, pelvic floor physical therapist, and sex therapist. Aim The aim was to explore the patient perceptions of benefit from management of their sexual dysfunction by a biopsychosocial multi-disciplinary team. Methods A survey was e-mailed to women patients seen by multi-disciplinary teams at 2 different settings: San Diego Sexual Medicine or Mayo Clinic Women's Health Clinic during a 27-month period. Data are reported using summary statistics for age and count for remaining survey responses. Cochran-Armitage tests for trend were used to compare pre- and post-comfort levels. Outcomes Main outcome measures included perceived benefit of being managed in a team-based model of care, level of benefit and satisfaction from each provider, and difference from pre-conceived level of comfort to actual comfort after each provider visit. Results 89 of 270 e-mailed surveys were analyzed. Patient populations (mean age 47.6, range 23–77 years) were similar between sites. Overall, 82% of respondents reported moderate/great benefit from the team-based model; 72.1% reported management by all 3 providers valuable/extremely valuable; and 84.3% were somewhat/very satisfied with the model. Women endorsed specific ways in which they benefitted from the team-based model including: improved sexual function (58.1%), feeling validated (72.1%) and listened to (62.8%), that they better understood their health concerns (65.1%), that their partner better understood their health concerns (46.5%), and feeling normal (46.5%). There were no significant differences between the 2 clinics in terms of patient-perceived benefit, value, or satisfaction. Conclusions The team-based model of care for management of sexual dysfunction in women including a medical provider, physical therapist, and sex therapist is associated with patient-perceived benefit, satisfaction, and value.

ObjectiveCurrently, there are no reliable biomarkers for predicting therapeutic response in patients with rheumatoid arthritis (RA). The synovium may unlock critical information for determining efficacy, since a reduction in the numbers of sublining synovial macrophages remains the most reproducible biomarker. Thus, a clinically actionable method for the collection of synovial tissue, which can be analyzed using high‐throughput strategies, must become a reality. This study was undertaken to assess the feasibility of utilizing synovial biopsies as a precision medicine‐based approach for patients with RA.MethodsRheumatologists at 6 US academic sites were trained in minimally invasive ultrasound‐guided synovial tissue biopsy. Biopsy specimens obtained from patients with RA and synovial tissue from patients with osteoarthritis (OA) were subjected to histologic analysis, fluorescence‐activated cell sorting, and RNA sequencing (RNA‐seq). An optimized protocol for digesting synovial tissue was developed to generate high‐quality RNA‐seq libraries from isolated macrophage populations. Associations were determined between macrophage transcriptional profiles and clinical parameters in RA patients.ResultsPatients with RA reported minimal adverse effects in response to synovial biopsy. Comparable RNA quality was observed from synovial tissue and isolated macrophages between patients with RA and patients with OA. Whole tissue samples from patients with RA demonstrated a high degree of transcriptional heterogeneity. In contrast, the transcriptional profile of isolated RA synovial macrophages highlighted different subpopulations of patients and identified 6 novel transcriptional modules that were associated with disease activity and therapy.ConclusionPerformance of synovial tissue biopsies by rheumatologists in the US is feasible and generates high‐quality samples for research. Through the use of cutting‐edge technologies to analyze synovial biopsy specimens in conjunction with corresponding clinical information, a precision medicine–based approach for patients with RA is attainable.

Objective To describe the occurrence and trend of concussions during the international ice hockey tournaments. Design Register study. Setting The International Ice Hockey Federation (IIHF) World Championships and Olympic Winter Games. Participants A total of 3293 games were played in the 169 tournaments by 1212 teams (26130 players) comprising 142244 athletic game exposures. Outcome measures One hundred and sixty concussions were observed. Main Results The average injury rate (IR) for concussion was 1.1 per 1000 ice hockey player-games for all IIHF World Championship tournaments (WC). The injury rate was highest in men's WC A-pool tournaments and Olympic Winter Games (OWG) (IR 1.6), and lowest in women's WC and OWG (IR 0.9). However, the annual injury rate for concussion in men's tournament has been lower than that in World Junior tournaments since 2012. When concussion occurred in a contact with a flexible board injury rate was 0.2 per 1,000 player games and 1.1 if a board and glass were traditional [RR 6.4, (95% CI 1.50–27.61]. In men's tournaments the trend of concussions caused by illegal hits decreased over a study period. After the 2012 Zurich Consensus Guidelines none of the concussed players returned to a play during a same day in men's WC tournaments. Conclusions The risk of concussion was significantly lower if games were played on rinks with flexible board and glass. Between 2006 and 2015, the annual risk of concussion in men's WC has been decreasing most likely due to the decreasing number of concussions caused by illegal hits.

347 Background: 9,704 was the first phase 3 pancreatic cancer trial to validate the prognostic value of postresection CA19-9 for overall survival (OS), with values > 90/180 associated with worse OS. All pts received adjuvant gemcitabine or 5-FU and chemo-radiotherapy (RT). This analysis evaluates patterns of disease failure. Methods: SMS was negative, positive, or unknown. CA19-9 was analyzed at cut points 90, 180 and continuously. LRF and DF were estimated by cumulative incidence and Gray’s test compared. Cox hazard models were used for multivariate analyses (MVA) and included treatment, tumor site, size and nodal status. To adjust for multiple comparisons a p-value < 0.01 is statistically significant and 0.01 to < 0.05 a trend. Results: 538 pts accrued, with 451 eligible and analyzable for SMS and 385 for CA19-9. For CA19-9, 132 (34%) were Lewis Antigen negative (no CA19-9 expression), 200 (52%) < 90 and 220 (57%) < 180. 188 (42%) had negative margins, 152 (34%) positive and 111 (25%) unknown (i.e., no margin comment in path report; shown to have outcomes similar to negative margin pts). Pts with CA19-9 ≥ 180 were more likely to have tumors ≥ 3 cm and pts with positive SMS more likely to have KPS 60 - 80, T3/T4, or N1 disease. On univariate analysis (UVA) CA19-9 cut at 90 was associated with significant increases in both LRF (trend) and DF; in the gemcitabine arm this was seen in DF, not in LRF; in the 5-FU arm it was seen in both. Results were similar at the 180 cut point and continuously. SMS on UVA was not associated with increase in LRF/DF; see Table. On MVA, CA19-9 > 90 was significantly associated with LRF and DF; positive SMS showed only a trend for DF. Conclusions: Postresection CA19-9 has significant association with both LRF and DF not seen with SMS. These findings support continued use of RT in trials and consideration of dose intensification among pts with elevated postresection CA19-9. Grants: NCI U10, CA21661, CA37422, CA180868, CA180822.

368 Background: 5-Fluorouracil (5FU) and mitomycin-C (MMC) chemoradiation for anal cancer is associated with high rates of acute morbidity. We have previously shown that dose-painted IMRT (DP-IMRT) significantly reduces grade 3+ GI and dermatologic acute toxicity, as compared to the RTOG 9811 5FU/MMC arm, which used non-conformal radiation techniques. We now report on the two-year outcomes of this DP-IMRT approach. Methods: T2-4N0-3M0 anal canal cancers received 5FU (1,000 mg/m2/day 96 hour infusion) and MMC (10 mg/m2 bolus) days 1 and 29 of DP-IMRT prescribed as follows - T2N0: 42 Gy elective nodal and 50.4 Gy anal tumor planning target volumes (PTVs), 28 fractions; T3-4N0-3: 45 Gy elective nodal, 50.4 Gy ≤ 3 cm and 54 Gy > 3 cm metastatic nodal and 54 Gy anal tumor PTVs, 30 fractions. The following two-year outcomes were assessed: local-regional (LRF) and colostomy failures (CF) using the cumulative incidence method, and disease-free (DFS), overall (OS) and colostomy-free survivals (CFS) using the Kaplan-Meier method. Results: Of 63 accrued patients, 52 were analyzable. Median age was 58 years; 81% female; 54% stage II; 25% IIIA; 21% IIIB. Median follow-up was 23.2 months (0.2-33). Two-year LRF, CF, DFS and 95% confidence intervals are 20% (9%, 31%), 8% (0.4%, 15%) and 77% (62%, 86%), respectively. The causes of death for the 7 patients that died are: anal cancer in 5, morbidity in one and second primary outside the radiation field in one. Two-year comparison data from the RTOG 9811 5FU/MMC arm are shown in the table below. Conclusions: DP-IMRT with 5FU/MMC for the treatment of anal canal cancer yields similar two-year outcomes as the RTOG 9811 conventional radiation, 5FU/MMC arm. Because of the associated acute toxicity sparing, DP-IMRT will be used as the platform, and may allow for radiation dose escalation, in future RTOG anal canal trials.

367 Background: On initial publication of GI Intergroup RTOG 98-11, concurrent chemoradiation with 5FU+mitomycin (MMC) decreased colostomy failure (CF) vs induction plus concurrent 5FU+cisplatin (CDDP), but did not significantly impact disease free or overall survival (DFS, OS). The intent of the current analysis is to determine the long-term impact of treatment on survival (DFS, OS, colostomy-free [CFS]), CF and relapse (local-regional [LRF], distant [DM]) in this patient group. Methods: Stratification factors included gender, clinical node status, and primary size. DFS/OS were estimated univariately by Kaplan-Meier method and treatment arms compared by log-rank test. Time to relapse/CF were estimated by cumulative incidence method and treatment arms compared by Gray's test. Multivariate analyses were done with Cox proportional hazard models to test for treatment differences, adjusting for stratification factors. Results: Of 682 patients accrued, 649 were analyzable for outcomes. As seen in the table, 5-yr DFS and OS were statistically better for RT+5FU/MMC vs RT+5FU/CDDP (67.7 v 57.6%, p=.0.0045; 78.2 v 70.5%, p=0.021) with trends toward statistical significance for CFS, LRF, and CF (71.8 v 64.9%, p=0.053; 20 v 26.5%, 11.9 v 17.3%, p=0.092 and 0.075). Similar results were seen in multivariate analysis. Conclusions: Concurrent chemoradiation with 5FU-MMC has a statistically significant impact on DFS and OS vs induction + concurrent 5FU-CDDP and borderline significance for CFS, CF and LRF. Therefore, RT+5FU/MMC remains the preferred standard of care. Potential strategies to improve outcomes include treatment intensification and individualized molecular-based treatment.

333 Background: Primary pancreatic small cell carcinoma (SCC) is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions' experience with resectable pancreatic SCC. Methods: Six patients with pancreatic SCC at the Johns Hopkins Hospital (4 patients) and the Mayo Clinic (2 patients) were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data was analyzed, and the literature on pancreatic SCC was reviewed. Results: Median age at diagnosis was 50 years (range 27-60). Half of the patients were male, and half were known smokers. All six masses were limited to the pancreatic head. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There was no perioperative mortality, although three patients had postoperative complications. All six patients received adjuvant chemotherapy therapy, five of whom were given cisplatin and etoposide. Of these five patients, three were known to have received radiation, while the remaining two had a plan for radiation at an outside facility. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Conclusions: Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed improved survival rates when compared to prior experiences with both resected and unresectable cases. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.
