Dismal Prognosis

IntroductionPancreatic cancer (PC), even in the absence of metastatic disease, has a dismal prognosis. One-third of them are borderline resectable (BRPC) or locally advanced unresectable PC (LAUPC) at diagnosis. There are limited prospective data supporting the best approach on these tumours. Neoadjuvant chemotherapy (ChT) is being increasingly used in this setting.MethodsThis is a retrospective series of consecutive patients staged as BRPC or LAUPC after discussion in the multidisciplinary board (MDB) at an academic centre. All received neoadjuvant ChT, followed by chemoradiation (ChRT) in some cases, and those achieving enough downstaging had a curative-intent surgery. Descriptive data about patient’s characteristics, neoadjuvant treatments, toxicities, curative resections, postoperative complications, pathology reports and adjuvant treatment were collected. Overall survival (OS) and progression-free survival was calculated with Kaplan-Meier method and log-rank test.ResultsBetween August 2011 and July 2019, 49 patients fulfilled the inclusion criteria, and all of them received neoadjuvant ChT. Fluorouracil+folinic acid, irinotecan and oxaliplatin was the most frequently used scheme (77%). The most prevalent grade 3 or 4 toxicities were neutropenia (26.5%), neurotoxicity (12.2%), diarrhoea (8.2%) and nausea (8.2%). 18 patients (36.7%) received ChRT thereafter. In total, 22 patients (44,9%) became potentially resectable and 19 of them had an R0 or R1 pancreatic resection. One was found to be unresectable at surgery and two refused surgery. A vascular resection was required in 7 (35%). No postoperative deaths were observed. Postoperative ChT was given to 12 (66.7%) of resected patients. Median OS of the whole cohort was 24,9 months (95% CI 14.1 to 35.7), with 30.6 months for resected and 13.1 months for non-resected patients, respectively (p<0.001).ConclusionA neoadjuvant approach in BRPC and LAUPC was well tolerated and allowed a curative resection in 38.8% of them with a potential improvement on OS.

Background: Despite the scarcity of data based on randomized trials, FOLFIRINOX is widely used in the management of borderline resectable pancreatic cancer (BRPC) and locally advanced unresectable pancreatic cancer (LAPC). We investigated the clinical outcomes of neoadjuvant FOLFIRINOX in patients with BRPC and LAPC. Methods: This single-center retrospective analysis included a total of 199 consecutive patients with BRPC or LAPC who received conventional or modified FOLFIRINOX between February 2013 and January 2017. An independent radiologist reviewed all baseline computed tomography or magnetic resonance imaging scans were reviewed for vascular invasion status. Results: With median follow-up duration of 40.3 months [95% confidence interval (CI), 36.7–43.8] in surviving patients, median progression-free survival (PFS) and overall survival (OS) were 10.6 (95% CI, 9.5–11.7) and 18.1 (95% CI, 16.0–20.3) months, respectively. The 1-year PFS rate was 66.0% (95% CI, 65.3–66.7%), and the 2-year OS rate was 37.2% (95% CI, 36.5–37.9%). PFS and OS did not differ between BRPC and LAPC groups [median PFS, 11.1 months (95% CI, 8.8–13.5) versus 10.1 months (95% CI, 8.4–11.8), p = 0.47; median OS, 18.4 months (95% CI, 16.1–20.8) versus 17.1 months (95% CI, 13.2–20.9), p = 0.50]. Curative-intent conversion surgery (R0/R1) was performed in 63 patients (31.7%). C•A 19-9 response, objective tumor response to FOLFIRINOX, and conversion surgery were independent prognostic factors for OS. Conclusion: FOLFIRINOX was effective for management of BRPC and LAPC. Given the potential for cure, a significant proportion of patients can undergo conversion curative-intent surgery following FOLFIRINOX.

Tumour Implantation

Pancreatic adenocarcinoma (PDAC) is the fourth leading cause of cancer deaths among men and women, being responsible for 6% of all cancer-related deaths. Surgical resection offers the only chance of cure, but only 15 to 20 percent of cases are potentially resectable at presentation. In recent years, increasing evidences support the use of neoadjuvant strategies in pancreatic cancer in patients with resectable pancreatic cancer as well as in patients with borderline resectable or locally advanced PDAC in order to allow early treatment of micrometastatic disease, tumour regression, and reduced risk of peritoneal tumour implantation during surgery. Furthermore, neoadjuvant treatment allows evaluation of tumour response and increases patient’s compliance. However, most evidences in this setting come from retrospective analysis or small case series and in many studies chemotherapy or chemoradiation therapies used were suboptimal. Currently, prospective randomized trials using the most active chemotherapy regimens available are trying to define the real benefit of neoadjuvant strategies compared to conventional adjuvant strategies. In this review, the authors examined available data on neoadjuvant treatment in patients with resectable pancreatic cancer as well as in patients with borderline resectable or locally advanced PDAC and the future directions in this peculiar setting.

366 Background: The combination of gemcitabine and nab-paclitaxel (GA) in first line treatment (tx) of MPC has a modest survival advantage over gemcitabine (gem) alone, but adds significant toxicities (tox) and increased cost. Based on data suggesting that biweekly administration (adm) of gem-based combinations preserves efficacy and improves tox profile, our institution adopted a modified regimen of GA (mGA). Methods: This is a retrospective analysis of a prospectively maintained database of patients (pts) with pancreatic cancer treated with gem (1000 mg/m2) and nab-paclitaxel (125 mg/m2) on days 1 and 15 of a 28-day cycle. Survival curves were estimated using Kaplan-Meier method, with alive pts censored at time of last follow-up. Cost of tx includes cost of drugs, adm, and tox. Results: Of total 69 pts treated with mGA for MPC, locally advanced, or borderline resectable disease, 63 pts were evaluable for tox (table 1). A total of 49 pts (47 evaluable for response) received mGA for previously untreated MPC, with median progression free survival of 4.8 months(mo) (95% CI 2.6,7.4) and overall survival of 11.1 mo (95% CI 5.3,not reached). Overall, 27% of pts experienced neurotoxicity with rate of grade 3 tox of < 2%, and 8% required growth factors (GF). Average cost savings was $5500/pt/month with mGA compared to standard GA, excluding GF cost which was lower with mGA. Conclusions: A less intense regimen of GA maintains efficacy while significantly improving tox profile and cost in pts with MPC. [Table: see text]

406 Background: Survival of resectable pancreas cancer (RPC) treated with resection and adjuvant therapy is 22-28 months (mo). Locally advanced unresectable pancreatic cancer (LAPC) treated with combination chemotherapy have a median survival of 24 mo. The objective of this project is to evaluate the effect of neoadjuvant treatment on survival outcome of localized PC. Methods: Charts of localized PC patients treated at Emory University from 2009 to 2016 were reviewed. Information on demographics, stage and treatment was collected. Survival rates were estimated by Kaplan-Meier method and compared with log-rank test. A Cox proportional hazard model was fitted to estimate the adjusted effect of treatment on overall survival(OS). Results: A total of 415 patients were included; 144 RPC, 158 borderline resectable (BRPC) and 108 LAPC. Stage was determined at the multidisciplinary conference. The median age was 67.7 years (30-92); 49% male, and 63% Caucasians. The median OS for RPC, BRPC, and LAPC was 16.9, 14.6 and 10.9 mo, respectively. Stage, type of chemotherapy and age were significant predictors of OS after adjusting for gender, race, age, surgery, stage, chemotherapy, margins and radiation. Of the 144 RPC, 137 underwent surgery and 3 received neoadjuvant treatment; 73 RPC were followed in outside facility with missing follow up data. Of the 71 RPC treated at Emory; 91% received adjuvant gemcitabine. Of the 158 BRPC, 84 underwent surgery; 44 received FOLFIRINOX neoadjuvant therapy, 23 received gemcitabine/nab-paclitaxel, and 16 received gemcitabine single agent. BRPC patients who underwent resection had a median OS of 18.5 mo (95%CI: 14.2, 26.4), significantly longer than RPC (P = 0.044). Combination chemotherapy was significantly associated with improved OS at 36 mo (38.9%) when compared to single agent gemcitabine (6.3% at 36 mo) (p = 0.009). BRPC patients who received FOLFORINOX and surgery had a median OS of 31.5 mo. Conclusions: Overall survival of BRPC patients who undergo resection after FOLFIRINOX is significantly improved (more than doubled) compared to upfront resection for RPC. Preoperative therapy provides the best approach for systemic disease early in the course of treatment.

Cancer Of The Pancreas

Background. The problem of neoadjuvant treatment of locally advanced (LA), borderline resectable (BR) and resectable pancreatic cancer (RPC) is being actively discussed at the present time, although the indications for its use have not been fully determined. In our work, we want to discuss the outcomes of using neoadjuvant chemotherapy (NACT) in these patients. Materials and methods. From 2016 to 2020, 85 patients with pancreatic cancer were observed in the clinic (37 patients with LA cancer of the pancreas; 15 with BR cancer of the pancreas and 33 with RPC). Of these, men 33 (38.8%), women 52 (61.2%). The average age was 64 (3183) years. All groups had GEMOX (41.2%) and FOLFIRINOX (58.8%) regimens. Increased CA 19-9 above normal had, in the LA group 21 (56.6%); in the BR group 9 (60%); and in the resectable group 26 (78.8%). From 3 to 6 courses of NACT were carried out, followed by computer tomography control and decision-making on treatment tactics. Results. In the LA group, the GEMOX (n=15) and FOLFIRINOX (n=22) modes were used. When evaluating the results after 1 follow-up examination after 2.5 months. found: 2 patients died; progression 14 patients (37.8%); remained inoperable 16 patients (43.2%), of whom 9 received radiation therapy. Removal of the primary tumor was performed in 5 patients (13.9%). The average OS in this group was 15 months. Fifteen patients with BR pancreatic tumors were observed. NACT was carried out with the same regimens GEMOX (n=7) and FOLFIRINOX (n=8) for 2.5 months. When evaluating the results after 1 follow-up examination after 2.5 months was found: 1 (7.7%) patient died; progression was noted in 6 (40%) patients; in 1 (7.7%) patient, surgical treatment was not performed due to pronounced concomitant diseases. Surgical treatment was performed in 7 (46.7%) patients. 33 patients were prescribed NACT for RPC. The main criteria for prescribing NACT for formally resectable pancreatic cancer were a high CA 19-9 level (100 IU/ml) [n=26 (75%)] and a large primary tumor [n=7 (25%)]. All patients received the same regimens for 3.3 months. up to 1 control. When evaluating the results, the following results were obtained: 1 (3%) patient died; 3 (9.3%) patients were not operated on due to refusal from surgical treatment; 7 patients (21.9%) were not operated on due to progression. Surgical treatment was performed in 22 (66.7%) patients; Whipple procedure in 17 patients, distal resection in 3 patients, total pancreatoduodenectomy in 2 patients. At the same time, complete morphological responce was noted in 2 (9%) patients, R0 resection in 19 (86%) patients, R1 in 1 patient (4.5%). The median survival rate of the operated patients was 20.2 months (CI 13.227.2 months). Most patients (65.9%) had a high level of CA 19-9, which was studied in dynamics and used as a marker of the biological activity of the tumor. Conclusion. Thus, we can claim that NACT is absolutely indicated for all patients with LA and BR pancreatic cancer, and its role in the selection of the most favorable in relation to the prognosis of patients is indisputable. Perioperative chemotherapy in patients with RPC is still controversial; however, having in mind the results in groups with LA and BR pancreatic cancer and the literature data, we dare to assume that for this issue it is a matter of time and future randomized trials. And here an important role can be played by the CA 19-9 level, which characterizes a biologically aggressive tumor, but again, prospective randomized studies are required to study this issue in more detail.

Biological Variables

e15712 Background: Accurate selection of patients based on radiological and biological variables is crucial to avoid over treatment and unnecessary R1 resection in pancreatic cancer (PC). Methods: We retrospectively investigated 73 patients diagnosed with PC treated between January 1998 to October 2015. We applied NCCN definitions for Resectable (RD), borderline resectable (BRD) and unresectable disease(URD). Logistic regression was used to identify significant indicators of R0 resection. Odds ratios were used to compare differences of overall survivability by R0 and No surgery. Fisher’s Exact Test was used for significance on all tabulated data. Wilcoxon Rank-Sum was used for the comparison of two medians and Kruskal-Wallis to compare more than two medians, and log-rank test was used to compare Kaplan-Meyer Curves. Results: Radiologically RD comprised 21% (15/73) of total cases, 80% (12/15) of these underwent R0 resection. URD comprised 79% (58/73). Patients presenting with abdominal pain were 2.5 times (Odds Ratio; p = 0.0275) more likely to be URD. The mean tumor size for R0 resectability was 2.28 cm (n = 12). The median CA 19-9 for URD was 1473 vs 162 for RD (p = 0.0124). Stage at presentation and resectability were statistically associated. (p = 0.0002): 100% of Stage 1 (n = 4) and, 27% of Stage 2, (11/41) were resectable. Twenty-three cases were identified as BRD, 21/23 received neoadjuvant chemotherapy, 47.83% had radiological PR, 28.26% had SD and 23.91% PD. There was no association between type of Neoadjuvant treatment (Chemo XRT vs Chemotherapy) and radiological response (p = 0.8798). None of the 21 BRD patients underwent surgery. Median Overall Survival for R0 resection was 22.3 months (95% CI 15.23, 36.50) vs. 5.1 who did not have surgery (95% CI 3.55, 7.57) (p = 0.0010). Conclusions: Nearly 80% patients identified as resectable on imaging underwent R0 resection. Although there were partial responses seen in BRD patients that underwent neoadjuvant treatment eventually none underwent R0 resection. Patients presenting with abdominal pain and high CA19-9 ( > 1400 U/ml) are likely to URD. Early stage and R0 resection were associated with positive outcomes.
