Abstract Introduction/Objective Assessing p53 mutation on biopsies could provide prognostic and therapeutic planning information, as it predicts worse outcomes for patients with endometrioid adenocarcinoma (EA). Immunohistochemistry (IHC) mutation pattern staining varies, easily causing misinterpretation. This study was designed to see if education clarifying staining issues would increase reproducibility, and if mutations detected in this setting were of prognostic import. Methods/Case Report p53 IHC on 46 FIGO grade 1 EA biopsies was scored by blinded participants. Education was provided regarding internal controls (IC), and common misinterpretations. The participants rescored to assess reproducibility. Outcome parameters (clinical stage [CS], progression free survival, higher FIGO grade on resection, and presence of mismatch repair mutations) were also assessed. Results (if a Case Study enter NA) 25% of scores changed post-education. Intraclass correlation among raters was 0.29 pre and 0.43 post (from fair to moderate). Mutation status changed in 5 cases. 2/5 caught IC failure for 1 case. Post-participation surveys found 0 participants were previously familiar with “high wild type,” and 60% were unfamiliar with cytoplasmic staining pattern, the possibility for heterogeneity, and necessary ICs. Every participant agreed grading was easier following education. Out of 6 patients with high CS disease (IIIC-IV), none had p53 mutation. 2/11 cases with higher FIGO grade (2-3) on resection had mutation. One patient had recurrence with no detectable mutation. 15/46 patients had MMR results available. No p53 mutation was detected in those with a loss of MLH1 and PMS2 (n=8). Conclusion Education on IHC issues can increase reproducibility in scoring, though overall reproducibility on biopsies was still subpar. Mutation detected in this setting did not correlate with current outcome parameters. Given the possibility of heterogenous expression and difficulties interpreting edge effect and assessing ICs in scant specimens, p53 IHC on EA biopsies is not recommended.

e16511 Background: Pelvic lymph node dissection (LND) requirement to adequately stage endometrial cancer has been subject of debate. We conducted an outcome analysis of clinical stage I endometrioid endometrial adenocarcinoma (EEA) patients who underwent surgery with tailored LND and adjuvant therapy (radiation (RT) or chemotherapy) between 1997 and 2008. Methods: Retrospective chart review was performed at our institution. All patients underwent exploratory laparotomy, cytology, total abdominal hysterectomy and bilateral salpingoophorectomy. Pelvic and para-aortic LND was perforned in high-risk patients when technically possible. Cox proportional hazards and the Kaplan Meier method were used for data analysis. Results: 119 patients (stage I 92, II 11, III 15, and IV 1) were identified. Median BMI was 34 and 81% had significant co-morbidities. 50% underwent para-aortic LND (median 4 nodes) and 25% underwent pelvic LND (median 15 nodes), of whom 8% and 10% were positive, respectively. Postoperative complications occurred in 22%. 26% received RT. With a mean follow-up of 20 months, 5-year progression-free survival (PFS) and overall survival (OS) was 71% and 84%. The OS for stage I and IIIC was 88% and 83%, respectively. OS for patients with or without LND was not statistically different ( 73% vs.82%). 12 (10%) recurrences were noted, 8 of which were hematological (HF) with a 5-year HF probability of 21%. On multivariate analysis only myometrial invasion > 50% was independent risk factor for HF. Patients receiving RT showed a trend toward decreased in local recurrences ( 0% vs.30% p = 0.1) but no improvement in OS. Conclusions: In patients with EEA, a tailored approach to LND and adjuvant therapy results in good outcome, but many still have therapy-associated adverse events. Although no difference was found in OS between patients who underwent LND and those who did not, similar survival for patients with stages I and IIIC suggests that therapy directed by the knowledge of nodal status may have an impact on survival. No significant financial relationships to disclose.

Cyclophosphamide exhibits the weakest therapeutic effect compared with vincristine and doxorubicin in the CHOP (C, cyclophosphamide; H, doxorubicin; O, vincristine; and P, prednisolone) chemotherapeutic protocol for the treatment of canine lymphoma. Twenty dogs with multicentric lymphoma were treated using the LHOP protocol, which used l-asparaginase in place of cyclophosphamide, and the outcomes were historically compared with those of dogs that received CHOP chemotherapy in the same institution. No significant differences were found in age (p = 0.107), body weight (p = 0.051), sex (p = 0.453), clinical stage V (p = 1), substage b (p = 0.573), T-cell phenotype (p = 0.340), overall response (p = 1), and hypercalcaemia status (p = 1) between the LHOP and CHOP groups. The adverse effects of l-asparaginase were well tolerated and self-limiting. The median PFS (progression-free survival) and median ST (survival time) in the LHOP group were 344 days (range: 28–940 days) and 344 days (range: 70–940 days), respectively. The median PFS and median ST in the CHOP group were 234 days (range: 49–1822 days) and 314 days (range: 50–1822 days), respectively. The dogs that received LHOP chemotherapy had a significantly longer PFS than the dogs that received CHOP chemotherapy (p = 0.001). No significant difference was observed in ST between the LHOP and CHOP groups (p = 0.131). Our study findings thus indicate that the LHOP protocol can be used as a first-line chemotherapeutic protocol in canine multicentric lymphoma.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC). Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.

Urocortin (UCN) is a 40-amino acid neuropeptide sharing 45% sequence homology with corticotropin-releasing factor (CRF). The human endometrium expresses both UCN and CRF, and CRF/UCN receptors type-1 (CRF-R1) and -2 (CRF-R2). CRF-R1 activation inhibits cell growth and proliferation of a tumor cell line derived from the human endometrium, and the UCN signaling pathway has been implicated in tumorigenesis of several tissues. Therefore, we investigated whether UCN mRNA and peptide are expressed by human endometrial adenocarcinoma, and whether their expression changes compared to controls. Samples of well (grade 1; n = 6 endometrioid adenocarcinoma, of whom n = 1 with squamous differentiation, and n = 1 clear-cell carcinoma) and poorly differentiated (grade 3; n = 3 endometrioid adenocarcinoma) endometrial adenocarcinoma were collected from nine women (age range 61–79 years) enrolled at the time of diagnosis. Healthy endometrium was collected from postmenopausal women (controls; n = 13; age range 64–78 years), who underwent hysterectomy for uterine prolapse. Immunohistochemistry was used to evaluate cellular UCN localization, with the intensity of immunostaining scored on a subjective scale. Quantitative real-time reverse transcriptase (RT)-PCR analysis was used to estimate mRNA expression changes and restriction analysis was used to confirm PCR products identity. UCN mRNA expression was significantly reduced (P < 0.0001) in endometrial adenocarcinoma than in healthy controls. Immunoreactive UCN was found in luminal and glandular epithelial cells in healthy, but not in neoplastic samples. UCN mRNA and peptide expressions are decreased in endometrial adenocarcinoma. These data and the evidence that endometrial cancer expresses UCN receptors and UCN is involved in tumorigenesis of several tissues together suggest a role for UCN in endometrial tumoral cell growth and proliferation.
