e18610 Background: Early stage pancreatic ductal adenocarcinoma (PDAC) account for up to 30% of newly diagnosed patients. Until recently, the mainstay of treatment remained curative-intent surgery followed by adjuvant chemotherapy. More recently, the incorporation of neoadjuvant therapy (NAT) has demonstrated clinical benefit. The two commonly used regimens are 5-Fluorouracil, Leucovorin, Oxaliplatin and Irinotecan (FOLFIRINOX), or Gemcitabine and nab-Paclitaxel. Limited data is available to differentiate outcomes between the 2 common NAT regimens. We conducted a retrospective review to assess the rates of disease recurrence and progression after neoadjuvant chemotherapy and to identify any associations that may predict early recurrence. Methods: A retrospective review was conducted of all patients diagnosed with PDAC from 2017-2019 at Allegheny General Hospital. Data analysis was completed using IBM SPSS v23. Disease recurrence or progression was assessed radiologically, and time to progression was calculated as time (months) since diagnosis to evidence of radiological progression. Results: Out of 171 patients reviewed, 56 were deemed resectable or borderline resectable and underwent curative-intent surgery and were included in the analysis. Median age was 68, and 12 (41%) were male. Majority of the patients were white (90%). 29 (52%) patients received neoadjuvant chemotherapy: 16 (55%) received FOLFIRINOX, 12 (41%) received Gemcitabine with nab-Paclitaxel, and 1 received another regimen. 9 patients out of 16 (56%) that received FOLFIRINOX progressed, and 5 out of 12 patients (42%) who received Gemcitabine with nab-Paclitaxel progressed. Patterns of progression in those that received FOLFIRINOX: 1 (11%) within 6 months, 4 (44%) between 6-12 months, and 4 (44%) after 12 months. Of those that received Gemcitabine with nab-Paclitaxel, 2 (40%) progressed within 6 months, 1 (20%) progressed between 6-12 months, and 2 (40%) progressed after 12 months. On multivariate analysis, no association was identified to predict progression. Conclusions: There was no significant difference in disease progression rates among patients that received neoadjuvant FOLFIRINOX versus Gemcitabine and nab-Paclitaxel (42% vs. 56%; p = 0.46). No predictive associations were identified in patients with disease recurrence. Study limitations include a low sample size and retrospective analysis. Further, larger scale studies are warranted to better assess the difference in rates of progression after neoadjuvant FOLFIRINOX versus Gemcitabine and nab-Paclitaxel.[Table: see text]

225 Background: Surgical resection is the only potentially curative modality for PDAC. However, even after a successful surgical resection outcomes are poor due to both local and distant disease recurrence. Patients with early recurrence likely derive no benefit from surgery and could be considered for a non-surgical approach as initial therapy. Since the incidence of recurrent/metastatic disease at first post-operative staging scan is not well documented, our aim was to determine this incidence. Methods: This IRB-approved analysis identified all pts diagnosed with resectable PDAC that underwent surgery with intent to cure at the University of Miami/Sylvester Comprehensive Cancer Center between 2010 and 2012. Patients with imaging before and within 6 months after surgery were included. All post-operative CT scans performed within 3 months after surgery were reviewed for the presence of recurrent and/or metastatic disease. Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Results: Data from105 pts were analyzed. Mean age was 61, 63% were male, 91% had adenocarcinoma, 84% had disease in the head of the pancreas. 11 out of 85 (13%) pts had recurrent/metastatic disease detected on first post-operative CT scan; 64% stage IIB and 73% had positive lymph nodes. 54 out of 105 (51%) had disease progression. 60% had local recurrence, 40% had distant metastasis. The mean time from preoperative CT scan to surgery was 35 days. Patients with early and late recurrence had similar OS from diagnosis (median 27.7 and 27.1 months, respectively) but worse than those with no disease recurrence (median not reached, OS rate 78% at 36 months). Conclusions: The relatively high incidence (13%) of early recurrence in this retrospective cohort suggests that further studies aimed at improving patient selection for surgery are warranted and provides a strong rationale for the use of neoadjuvant therapy to select patients with early disease progression who would not have benefitted from surgery.

e16247 Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal solid tumors, predicted to become the second leading cause of cancer related death in some regions of the world. It often presents at an advanced stage, which contributes to poor five-year survival rates of 2%-9%, ranking firmly last amongst all cancer sites in terms of prognostic outcomes for patients. Only about 20% of the cases are diagnosed early enough to undergo surgical resection leading to complete remission. While chemotherapy has an established role in the setting of metastatic disease, utilizing it in the neo-adjuvant setting has been adopted by most institutes for resectable/ borderline resectable cases. Ongoing trials are exploring the use of different regimens in the neo-adjuvant setting. The aim of our study was to identify patients with resectable/borderline resectable PDAC undergoing neoadjuvant chemotherapy and differences in surgical outcome based on the regimen received i.e gemcitabine/ nab-Paclitaxel vs FOLFIRINOX. Methods: A retrospective review was conducted of all patients diagnosed with PDAC from 2017-2019 at Allegheny General Hospital. Data analysis was completed using IBM SPSS v23. Summary statistics were presented using percentages for categorical variables and medians with interquartile ranges for continuous variables. Results: Out of 121 patients who received and completed treatment in our institution, 30 underwent neoadjuvant chemotherapy treatment followed by surgical intervention. 21 (70%) patients were found to be borderline resectable, 8 (27%) patients were resectable and 1 patient had locally advanced PDAC. 16 (53%) patients received FOLFIRINOX compared to 13 (43%) patients received gem/nab-paclitaxel. Among patients who received neoadjuvant FOLFIRINOX, 5 out of 16 (31%) patients had moderate to significant treatment response at the time of surgery compared to 7 out of 13 (54%) patients who received gemcitabine/nab-paclitaxel. Conclusions: Our study revealed no significant difference (p=0.21) between the patients who received neoadjuvant gemcitabine/nab-paclitaxel vs FOLFIRINOX in terms of treatment response assessed pathologically at the time surgical resection. We recognize the limitations of our study in terms of it being a retrospective analysis with a small sample size and therefore further prospective and randomized controlled trials are needed to determine the most suitable and effective regimen in the neoadjuvant setting for resectable/borderline resectable PDAC patients. Response to treatment among different chemotherapy groups.[Table: see text]

AbstractThe optimal regimens of neoadjuvant chemotherapy (NAC) and its biological and physiological modification of the tumor microenvironment (TME) in patients with borderline resectable pancreatic ductal adenocarcinoma (BR PDAC) remain unknown. A deeper understanding of the complex stromal biology of the TME will identify new avenues to establish treatment strategies for PDAC patients. Herein, we sought to clarify whether stromal remodeling by NAC affects recurrence patterns and prognosis in BR PDAC patients. We retrospectively analyzed data from 104 BR PDAC patients who underwent pancreatectomy with or without NAC (upfront surgery [UpS], n = 44; gemcitabine + nab-paclitaxel [GnP], n = 28; and gemcitabine + S-1 [GS], n = 32) to assess the correlations of treatment with early recurrence, the stromal ratio, and Ki-67 levels. Eighty-six patients experienced recurrence, and those with liver metastasis had significantly shorter recurrence-free survival than those with other recurrence patterns. The frequency of liver metastasis was significantly higher in patients with a low stromal ratio than in those with a high stromal ratio in the NAC group but not in the UpS group. Patients in the GnP group had significantly higher Ki-67 than those in the GS and UpS groups. A low stromal ratio was positively correlated with high Ki-67 in the NAC group but not in the UpS group. The low stromal ratio induced by NAC promoted early liver metastasis in patients with BR PDAC. Our findings provide new insights into the complexity of stromal biology, leading to consideration of the optimal NAC regimen.

e18039 Background: Angiosarcoma of the head and neck (ASHN) is a rare entity and confers substantial morbidity and mortality. Yet, the optimal management of ASHN remains unclear. This study aimed to describe the epidemiology of ASHN and to identify the most favorable treatment approach. Methods: We performed a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, using the PubMed (Medline), EMBASE, and Cochrane Library databases, queried from 1990 until present. Articles in the English language reporting on survival outcomes of adult primary ASHN treated with curative-intent, were included. All estimates were weighted based on sample size. Analysis of variance (ANOVA) and two-sample t-tests were used as appropriate. This study was registered with PROSPERO, CRD42021220970. Results: A total of 3652 studies were identified, with 14 articles reporting on 2265 ASHN patients, meeting inclusion criteria. Mean ± SD age was 70.6 ± 7.7 years with 1621 (66.6%) men and 812 (33.4%) women. ASHN involved the scalp (n = 176, 57.9%) and the face (n = 128, 42.1%). 249 patients had early stage I-II disease (39.6%) whereas 379 had late stage III-IV disease (60.4%). Most (n = 529, 45.6%) received surgery and radiotherapy (RT), 305 (26.3%) received surgery alone, 210 (18.1%) received definitive RT/chemoradiotherapy (CRT), 75 (6.5%) received surgery and CRT, and 33 (2.8%) received surgery and chemotherapy. Negative margins were achieved in 471 (55.9%) whereas 371 (44.1%) had positive margins. Mean ± SD follow-up was 41.7 ± 15.4 months. Weighted mean, 1-, 5-, and 10-year overall survival (OS) were 26.9 months, 67.3%, 30.6%, and 20.8% respectively. Mean and 5-year disease-specific survival (DSS) were 72.9 months and 50.3% respectively. Mean ± SD local recurrence rate (LRR) was 32.1 ± 11.7%. Median RT dose delivered was 60 Gy (interquartile range: 60-70). Patients who received surgery had a significantly higher mean OS (34.9 vs. 18.7 months, P = 0.04) and 5-year OS (30.1 vs. 14.2%, P = 0.01) compared with those who did not receive surgery. There was no significant difference in mean OS for receiving adjuvant chemotherapy (P = 0.99) or RT (P = 0.51). Conclusions: In the largest ASHN study to date, definitive surgical resection was associated with an improvement in OS. Multimodality treatment did not confer an OS benefit. Randomized trials are needed to establish the optimal treatment approach for ASHN.

e15714 Background: Although combination of fluorouracil, irinotecan, Leucovorin and oxaliplatin [FOLFIRINOX] significantly increases survival in metastatic pancreatic cancer (MPC) compared to gemcitabine based on ACCORD trial, the efficacy and toxicities may be different in non-metastatic setting. We reviewed our institution’s experience with FOLFIRINOX in locally advanced pancreatic cancer (LAPC). Methods: We performed a retrospective review of clinical outcomes in patients diagnosed with LAPC and receiving between June 2010 and July 2015, with at least one year of follow up from diagnosis, at University of Alabama at Birmingham. Results: Total of 41 patients with ECOG performance scale of 0 or 1, who underwent neoadjuvant chemotherapy with FOLFIRINOX were assessed for clinical and pathological characteristics. Median age was 61 years (range 38-81) with 23 (56.1%) males, 28 (68.3%) Caucasians and 16 (39.0%) underwent surgery (whipple operation) post-neoadjuvant. Median OS (time of diagnosis to last follow up/death) is 83.5 months for whole cohort, survival rates are 94.9% at 1 year, 58.4% at 2 year, and 33.3% at 5 year.Median OS for those who underwent surgical resection following the chemotherapy is 38.6 months; 100% at one year, 85.1% at 2 year, 55.3% at 5 year; while median OS for those who did not undergo surgery is 21.8 months; 91.7% at one year, 41.5% at 2 year, 20.7% at 5 years. Among those who underwent surgery, the median recurrence free survival (time from surgery to relapse/progression) is 19.9 months with liver being common recurrence site (81%). There was no post-operative mortality in 30 days. Grade 3-4 toxicity occurred in 46% ( vomiting (12%), fatigue (28%) and neutropenia (54%), febrile neutropenia (9%)). There is a significant difference between surgery and non-surgery groups (p = 0.012) for improved OS by log-rank test. Conclusions: Neoadjuvant FOLFIRINOX treatment associated with high response rates leading to surgical resection in our cohort. Patients who underwent neoadjuvant chemotherapy followed by resection for LAPC have statistically significant improved OS compared to those who did not.

Objectives: To determine the factors that may be used as the prognostic parameter for the therapeutic efficacy of neoadjuvant chemotherapy, which can be used to revising the management of early stage cervical cancer patients with large lesions. Methods: This was a retrospective cohort study. The study was conducted in the Dr. Cipto Mangunkusumo Hospital, Faculty of Medicine, University of Indonesia. The subjects were 15 cervical cancer stage IB2 and IIA patients with lesions’ size of > 4 cm, who would be treated with neoadjuvant chemotherapy, consisted of cisplatin 50 mg/m2, vincristine 2 mg/m2 and bleomycin 15 mg regiment. The patients’ response would be evaluated after completing 3 series of chemotherapy. Data was retrieved from medical records and cervical biopsy paraffin blocks and examined histopathologically using IHC staining to see expression of caspase-3 with histoscore assessment score. Data was analyzed by univariate, bivariate analysis. Results: Response to PVB neoadjuvant chemotherapy was found in 5 out of 15 patients. None of the clinicopathology variables can be used to predict response to therapy. Expression of caspase-3 as a marker of apoptosis, can not predict the response of the therapy before administrating neoadjuvant chemotherapy either. There is a significant difference between the levels of caspase-3 in epidermoid carcinoma with adenocarcinoma, with p value of 0.02 (RR 6;95% CI 1.69-21.26). Conclusion: Clinicopathologic factors and the expression of caspase-3 before getting chemotherapy neoadjuvant can not predict the succeed of the therapy.

The objective of this paper is to clarify the role of cytoreductive surgery and salvage chemotherapy in the management of recurrent advanced epithelial ovarian carcinoma (RAEOC) and to identify factors affecting disease recurrence. One hundred sixty seven patients with RAEOC treated at the Cancer Hospital of Fudan University between January 1986 and December 1997 were retrospectively reviewed. Survival was calculated by Kaplan-Meier method with difference in survival estimated by the log-rank test. Independent prognostic factors were identified by the Cox stepwise regression model and variants associated with disease recurrence were determined using logistic stepwise regression methods. The median age was 52 (range 27–72) years. Sixty (35.9%) patients underwent re-debulking surgery, 23 of them with residual disease ≤1 cm. There was a significant difference in survival between optimal and suboptimal groups, with an estimated median survival of 18 and 13 months, respectively (P = 0.021, χ2 = 9.42). When patients with suboptimal surgical results were compared to those with chemotherapy alone, there was a significant difference in median survival, 13 vs. 16 months (P = 0.0364, χ2 = 4.38). Residual disease after primary surgery, neoadjuvant chemotherapy, and salvage chemotherapy was a predictor of survival identified by Cox regression analysis, but secondary cytoreductive surgery did not reach a level of statistical significance (P = 0.0561). Logistic stepwise regression analysis showed that age, first-line chemotherapy, neoadjuvant chemotherapy, and the size of residual disease after primary surgical cytoreduction were factors affecting disease recurrence. We conclude that patients with RAEOC benefit from optimal secondary surgical cytoreduction. Should the recurrence not be optimally cytoreduced by surgery, alternative salvage chemotherapy is best for RAEOC.
