349 Background: Clinical staging of patients with pancreatic cancer is essential to determine if neo-adjuvant treatment, surgery or palliative treatment is required. Patients with early stage disease often receive upfront surgery, where as patients with more advanced disease often receive neo-adjuvant therapy. Therefore the accuracy of clinical staging significantly influences management decisions. This study investigates the correlation between clinical and pathologic staging for patients with stage I pancreatic cancer. Methods: A retrospective review of patients with pancreatic cancer in National Cancer Data Base from 1998-2006 was preformed. The clinical stage of patients with presumed stage I disease was compared to the postoperative pathologic stage. Cox proportional hazard ratio model and regression analysis were used to determine factors associated with mortality and upstaging, respectively. Results: 1697 patients with clinical stage I pancreatic cancer were divided into two groups. Group 1 was comprised of patients who were stage I postoperatively and Group 2 was comprised of patients that were upstaged to either stage II, III or IV postoperatively. There were 704 (41%) in group 1 and 993 (59%) in group 2. Within group 2, 595 (60%) were stage II, 321 (32%) were stage III and 77 (8%) were stage IV. Patients that were upstaged after surgery had an increased risk of mortality (HR 1.414, p < 0.001), whereas patients that received adjuvant chemotherapy had a decreased risk of mortality (HR 0.799, p < 0.001). Compared to Grade 1 tumors, Grade 2 and 3 tumors on biopsy were most likely to be upstaged on final pathology (p < 0.001). Conclusions: Patients with stage I pancreatic cancer are often candidates for upfront surgery, however this study demonstrates that a large number are upstaged on postoperative staging. Recognizing this may lead clinicians to administer neo-adjuvant treatment in a greater number of patients with early stage disease in order to optimize survival.

Small-cell lung cancer (SCLC) is one of the most aggressive tumors, with a rapid growth and early metastases. Approximately 5% of SCLC patients present with early-stage disease (T1,2 N0M0): these patients have a better prognosis, with a 5-year survival up to 50%. Two randomized phase III studies conducted in the 1960s and the 1980s reported negative results with surgery in SCLC patients with early-stage disease and, thereafter, surgery has been largely discouraged. Instead, several subsequent prospective studies have demonstrated the feasibility of a multimodality approach including surgery before or after chemotherapy and followed in most studies by thoracic radiotherapy, with a 5-year survival probability of 36–63% for patients with completely resected stage I SCLC. These results were substantially confirmed by retrospective studies and by large, population-based studies, conducted in the last 40 years, showing the benefit of surgery, particularly lobectomy, in selected patients with early-stage SCLC. On these bases, the International Guidelines recommend a surgical approach in selected stage I SCLC patients, after adequate staging: in these cases, lobectomy with mediastinal lymphadenectomy is considered the standard approach. In all cases, surgery can be offered only as part of a multimodal treatment, which includes chemotherapy with or without radiotherapy and after a proper multidisciplinary evaluation.

Abstract Pancreatic cancer is often detected late, when curative therapies are no longer possible. Here, we present non-invasive detection of pancreatic ductal adenocarcinoma (PDAC) by 5-hydroxymethylcytosine (5hmC) changes in circulating cell free DNA from a PDAC cohort (n = 64) in comparison with a non-cancer cohort (n = 243). Differential hydroxymethylation is found in thousands of genes, most significantly in genes related to pancreas development or function (GATA4, GATA6, PROX1, ONECUT1, MEIS2), and cancer pathogenesis (YAP1, TEAD1, PROX1, IGF1). cfDNA hydroxymethylome in PDAC cohort is differentially enriched for genes that are commonly de-regulated in PDAC tumors upon activation of KRAS and inactivation of TP53. Regularized regression models built using 5hmC densities in genes perform with AUC of 0.92 (discovery dataset, n = 79) and 0.92–0.94 (two independent test sets, n = 228). Furthermore, tissue-derived 5hmC features can be used to classify PDAC cfDNA (AUC = 0.88). These findings suggest that 5hmC changes enable classification of PDAC even during early stage disease.

Pancreatic cancer is a lethal disease, with mortality rates negatively associated with the stage at which the disease is detected. Early detection is therefore critical to improving survival outcomes. A recent focus of research for early detection is the use of circulating cell-free tumour DNA (ctDNA). The detection of ctDNA offers potential as a relatively non-invasive method of diagnosing pancreatic cancer by using genetic sequencing technology to detect tumour-specific mutational signatures in blood samples before symptoms manifest. These technologies are limited by a number of factors that lower sensitivity and specificity, including low levels of detectable ctDNA in early stage disease and contamination with non-cancer circulating cell-free DNA. However, genetic and epigenetic analysis of ctDNA in combination with other standard diagnostic tests may improve early detection rates. In this review, we evaluate the genetic and epigenetic methods under investigation in diagnosing pancreatic cancer and provide a perspective for future developments.

e15585 Background: Neuroendocrine carcinomas (NEC) of the cervix comprise only 2% of all cervical cancers. As a result, prospective data is limited and treatment guidelines rely on literature from lung NEC. The objective of this study was to examine and report on our experience in the management of this rare, aggressive disease. Methods: This was an IRB-approved, single-institution, retrospective review. Study criteria included patients with cervical NEC diagnosed between 1990-2011. Demographic, treatment and survival data was collected. Progression-free survival (PFS) and overall survival (OS) was defined as the time from date of initial treatment until progression or death respectively, or date of last contact. Results: A total of 24 patients met inclusion criteria. The median age at diagnosis was 43. Median PFS was 13.6 months and median OS was 16.4 months. The majority of patients had advanced-stage disease (61% stage II-IV, 39% stage I). Of the 9 patients with stage I disease, 4 were treated with platinum + etoposide-based neoadjuvant chemotherapy and 5 were treated with initial radical surgery. Seven of the 9 patients had post-operative adjuvant therapy consisting of chemotherapy, chemo-radiation or radiation only. Seven of the 9 patients (78%) were alive at last follow-up. Of the two patients who were deceased, one had metastatic disease found at surgery and the other declined adjuvant therapy and died of recurrence. Patients with stage II-IV disease (n=15) had a median PFS and OS of 11.5 and 12.1 months, respectively. Only 2 had no evidence of disease at last encounter. The remainder died without achieving remission. Patients with metastatic disease had significantly worse survival when compared to those with loco-regional disease with a median OS of 8 vs. 28 months (p = .03), respectively. Conclusions: We report one of the largest single-institution experiences of neuroendocrine cervical cancer. Advanced-stage patients had a poor prognosis regardless of therapy. However, multi-modality therapy in early-stage disease resulted in an excellent prognosis (78% survival) for these rare, highly aggressive tumors. These findings support the goal of curative intent for early-stage disease using multi-modality therapy.

e21038 Background: Up to 45% of stage I-II melanomas will relapse within 5 years, and some relapses occur more than 10 years after surgical resection. Little is known about the differences in tumor characteristics, including immunogenicity, of early- vs. late-relapsing melanoma, or the implication of these differences in response to PD-1 inhibition. Methods: A retrospective cohort study was conducted to compare time from definitive treatment of localized melanoma to relapse with response to pembrolizumab. Patients with prior stage I-II melanoma who relapsed, and then treated with pembrolizumab, were included in the study. Time to relapse was compared with overall response rate. Results: Among the study population, 66 patients initially presented with early stage disease that relapsed within the study period. The median time to relapse was 5 years (range 0.5-33 years, interquartile range 7.25, Q1 = 2, Q2 = 9.25). 9 patients (14%) relapsed within 2 years of surgery; these patients had a higher overall response rate to pembrolizumab than late-relapsing patients with marginal significance (88% vs 50%, p = 0.056). The difference became less significant when patients who relapsed before or after 5 years (70% vs 47%, respectively, p = 0.20), and before or after 10 years (64% vs 45%, p = .31). Conclusions: Patients with early-relapsing melanoma had higher ORR to pembrolizumab than patients with late-relapsing disease, with early relapse defined as earlier than 2 years from definitive surgical intervention. Late relapsing tumors may harbor mechanisms of resistance to immune checkpoint inhibition.

Purpose To evaluate the effect of combining circulating Epstein-Barr viral (EBV) DNA load data with TNM staging data in pretherapy prognostication of nasopharyngeal carcinoma (NPC). Patients and Methods Three hundred seventy-six patients with all stages of NPC were studied. Pretreatment plasma/serum EBV DNA concentrations were quantified by a polymerase chain reaction assay. Determinants of overall survival were assessed by multivariate analysis. Survival probabilities of patient groups, segregated by clinical stage (I, II, III, or IV) alone and also according to EBV DNA load (low or high), were compared. Results Pretherapy circulating EBV DNA load is an independent prognostic factor for overall survival in NPC. Patients with early-stage disease were segregated by EBV DNA levels into a poor-risk subgroup with survival similar to that of stage III disease and a good-risk subgroup with survival similar to stage I disease. Conclusion Pretherapy circulating EBV DNA load is an independent prognostic factor to International Union Against Cancer (UICC) staging in NPC. Combined interpretation of EBV DNA data with UICC staging data leads to alteration of risk definition of patient subsets, with improved risk discrimination in early-stage disease. Validation studies are awaited.

The records of all patients with clear-cell ovarian cancer (CCC) who underwent complete surgical staging and chemotherapy between 1984 and 2001 were reviewed and 39 patients identified as suitable for study. The mean patient age was 56 years, and the stage distribution was as follows: stage I, 53%; stage II, 13%; stage III, 32%; and stage IV, 2%. One in three patients with stage I disease developed recurrent disease despite adjuvant chemotherapy. Seventy percent of tumors demonstrated a response to combination carboplatin and paclitaxel. Tumors which had either a partial response or failed to respond to first-line chemotherapy demonstrated no response to second-line nonplatinum chemotherapy. Endometriosis was identified in 31% of tumors, and 18% of patients developed deep venous thrombosis (DVT); however, neither endometriosis nor DVT was associated with a poorer outcome. CCC has a high recurrence rate in early-stage disease despite adjuvant treatment with cytotoxic chemotherapy. Advanced disease does respond to carboplatin and paclitaxel, which should be the chemotherapeutic regimen of choice. New second-line agents are urgently required.

9068 Background: One the main reasons for delayed presentation of children with RB in India is non acceptance of enucleation. CT is being increasingly utilized as primary treatment of RB to reduce the tumor volume and thus avoid enucleation and/or external beam radiation (EBRT) in early stage disease and reduce the risk of relapse in advanced stage disease. Methods: This retrospective (from 1996 to 2001) study involved 62 Patients (pts) (30 were bilateral) who received CT consisting of monthly cycles of carboplatin, etoposide, vincristine and cyclophosphomide. Pts with stage I disease, were started on CT alone, whereas most of the other pts were also started on concurrent EBRT (50Gy). Where indicated, pts also received local therapy, usually cryotherapy & EBRT. Eyes which did not show response or had stable disease, were advised enucleation. Results: Majority of pts had Reese-Ellsworth groups IV-V (74.1%). 17 pts had Stg I, 22 Stg II, 17 Stg III & 6 Stg IV disease (St Jude’s). All pts received CT (median 12 cycles). Out of 92 eyes only 79 were evaluable (13 were already enucleated).The response rate was 73.2% (51.8% CR or near CR); 12.9% had progressive disease. 47 Pts (74%) received RT. Only 23 pts received focal treatment (Cryotherapy 15, laser 3, combination 5). Vision was present in 38 eyes (48.1%) at presentation. 26 eyes (68.4%) were finally saved with useful vision. 20 pts had recurrence. 18 have died (17 died of disease, 1 treatment related sepsis). In those following up in the clinic, survival is 77% for stage I; 78.5% for stage II; 41.6% for stage III. All stage IV pts have died except 1 with nodal disease. Conclusions: CT has a role in the management of RB, however unless it is coupled with good focal therapy the results are poor as shown here. Also longer follow-ups are required because of late recurrences. This data highlights that in developing countries the social reasons complicate patient treatment & compliance. Further efforts are needed to spread awareness of this disease so that patients are diagnosed and treated in earlier stages so as to improve the outcomes.

The Impact

367 Background: Pancreatic cancer carries a dismal prognosis, with surgical resection and adjuvant therapy offering the only hope for long-term survival. In recent years, neoadjuvant therapy (NAT) has been employed to optimize outcomes. This study evaluates the impact of NAT on survival in patients with resected stage I-III pancreatic cancer. Methods: The National Cancer Data Base (2003-2011) was analyzed for patients with clinical stage I-III resected carcinoma of the pancreas who underwent NAT or surgery first +/- adjuvant therapy. Univariate statistics were used to compare characteristics between groups. Analysis of variance and Kaplan Meier analyses were used to compare median survival for each clinical stage of disease. Multivariate analyses were performed using a Cox proportional hazards model. Results: 16,122 patients who underwent NAT and 16,869 patients who underwent surgery-first were included. Patients who underwent NAT tended to be younger, covered by private insurance, have a higher median income, greater comorbidities, higher clinical stage disease, and undergo a whipple. Additionally, NAT patients had a greater number of positive regional lymph nodes (9 vs. 6, respectively), although a similar number of nodes retrieved, and higher pathological stage disease. In patients with clinical stage I disease, adjuvant therapy was associated with improved median survival than NAT and surgery-alone (24.8, 18.5, 17.9 months, p < 0.0001, respectively). However, in stage II, adjuvant and NAT offered similar median survival, which was improved over surgery-alone (20.5, 20.1, and 12.4 months, p < 0.0001, respectively). In stage III, NAT had improved median survival than the other groups (19.6, 14.2, 8.6 months, p < 0.0001, respectively). In the multivariate survival analysis, patients who received NAT had a 22% lower hazard of mortality up to 5 years as compared to adjuvant therapy (p < 0.0001). Conclusions: Neoadjuvant therapy in advanced stage pancreatic cancer confers a survival benefit and may allow more patients to undergo surgery; NAT appears to offer similar survival as adjuvant therapy in early stage pancreatic cancer.
