Major Factors

Purpose. To identify major factors affecting the overall survival (OS). To select the cohort of patients with the best prognosis.Materials and methods. A retrospective analysis included data of 268 patients, 128 men and 140 women, with median age of 59±10,53 (30 to 83) years. For multivariate analysis of survival, patients were selected who underwent pancreaticoduodenectomy (PD) for ductal adenocarcinoma of the pancreatic head.Results. Our study demonstrated that histologically verified vascular invasion (detected only in 30 % of patients who underwent PD with resection of the major vessels) statistically significantly affected the OS. The increased CA19-9 level over 500 U / L (detected in 32,3 % of cases) is the factor that significantly worsens the OS. Patients with high grade adenocarcinoma have significantly better survival rates compared with patients who have moderately or poorly differentiated adenocarcinoma (p = 0.014; median 26 months, 95 % CI 4.4–47.6 versus median 17 months, 95 % CI 15–19, an median: 13 months, 95 % CI 5–21, respectively). Also, the use of adjuvant chemotherapy has a positive effect on long-term outcomes (p = 0.0001; median 26 months, 95 % CI 21.7–30.3 versus median 13 months, 95 % CI 11.3–14.7).Conclusion. A well-differentiated tumor and the use of adjuvant chemotherapy significantly increase the OS of patients. Poorly differentiated tumor, CA19-9 level over 500 U / mL and the histologically confirmed vascular invasion significantly worsen the prognosis of these patients.

AbstractImmunohistochemical level of IMP3-protein in patients with rectal cancer in clinical stage II (141), were correlated with sociodemographic, pathohistological and clinical indicators and duration of overall-survival and progression-free-survival. Vascular invasion was associated with IMP3-positive immunostaining (p < 0.001). Vascular invasion ratio in the group of poorly-differentiated-tumors was 21 times higher than in the group of well-differentiated-tumors. IMP3-positive patients lived 2.2 times shorter than negative (p < 0.001). Patients with well-differentiated-tumors lived 1.7 times longer than the subjects with poorly-differentiated-tumors (p < 0.001). Patients without vascular invasion lived 2.7 times longer than the subjects with vascular invasion (p < 0.001). The risk of mortality was 2.3 times higher for IMP3 positive patients (p = 0.027) and 10.4 higher for the patients with vascular invasion (p < 0.001). IMP3-negative participants had 2.3 times longer free interval without disease (p < 0.001). The free interval without disease was 3.6 times longer in the group without vascular invasion (p < 0.001). The risk of disease relapse in the IMP3 positive group was 5.3 times higher (p < 0.001) and with vascular invasion was 8 times longer (p < 0.001). The risk of disease relapse was 6.8 times higher in the group with vascular invasion (p < 0.001). Patients with rectal cancer and high IMP3-protein level will have a shorter overall survival relative to patients without or with low levels of IMP3. The analysis of IMP3 expression by immunohistochemistry pointed IMP3 as an independent prognostic factor of clinical stage II rectal cancer.

PurposeAdjuvant chemotherapy improves patient survival rates after resection for pancreatic adenocarcinoma, but the optimal duration and time to initiate chemotherapy is unknown.Patients and MethodsPatients with pancreatic ductal adenocarcinoma treated within the international, phase III, European Study Group for Pancreatic Cancer–3 (version 2) study were included if they had been randomly assigned to chemotherapy. Overall survival analysis was performed on an intention-to-treat basis, retaining patients in their randomized groups, and adjusting the overall treatment effect by known prognostic variables as well as the start time of chemotherapy.ResultsThere were 985 patients, of whom 486 (49%) received gemcitabine and 499 (51%) received fluorouracil; 675 patients (68%) completed all six cycles of chemotherapy (full course) and 293 patients (30%) completed one to five cycles. Lymph node involvement, resection margins status, tumor differentiation, and completion of therapy were all shown by multivariable Cox regression to be independent survival factors. Overall survival favored patients who completed the full six courses of treatment versus those who did not (hazard ratio [HR], 0.516; 95% CI, 0.443 to 0.601; P < .001). Time to starting chemotherapy did not influence overall survival rates for the full study population (HR, 0.985; 95% CI, 0.956 to 1.015). Chemotherapy start time was an important survival factor only for the subgroup of patients who did not complete therapy, in favor of later treatment (P < .001).ConclusionCompletion of all six cycles of planned adjuvant chemotherapy rather than early initiation was an independent prognostic factor after resection for pancreatic adenocarcinoma. There seems to be no difference in outcome if chemotherapy is delayed up to 12 weeks, thus allowing adequate time for postoperative recovery.

Introduction. For the difference from poorly differentiated, well differentiated endocrine carcinomas of the pancreas are the tumours in whom with aggressive surgery and chemotherapy fair results can be achieved. Objective. The aim of the study was to point out the importance of such treatment. Methods. Over a 6-year period eight patients (seven female and one male) of average age 51 years (ranging from 23 to 71 years) were operated on for well differentiated endocrine carcinoma: six of the head and two of the tail of the pancreas. There were two functional and six nonfunctional tumours. Pain in the upper part of the abdomen in seven, mild loss in weight in two, strong heartburn in two, obstructive jaundice in three, diarrhoea in one, sudden massive bleeding from gastric varicosities due to prehepatic portal hypertension caused by pancreatic head tumour in one, and bruise in one patient were registered preoperatively. US and CT in all, angiography in one, octreoscan in two and PET scan in one patient were performed. Whipple?s procedure was performed in six and distal pancreatectomy in two patients, as well as systemic lymphadenectomy in all and excision of liver secondary tumours in two patients. In the patient with massive gastric bleeding a total gastrectomy was performed first, followed by Whipple?s procedure a month later. Results. R0 resection was achieved in all patients. Lymph nodes metastases were found in six patients. Six patients were given chemotherapy. One patient died 3 years after surgery, seven are still alive, on average 2.5 years. A local recurrence after distal pancreatectomy that occurred 5 years after surgery was successfully reresected and the patient is on peptide-receptor radiotherapy. In other six patients there were no local recurence or distant metastases. Conclusion. With aggressive surgery and chemotherapy fair results can be achieved in well differentiated endocrine carcinomas of the pancreas.

373 Background: Ampullary neuroendocrine tumors (NET) make up < 1% of all gastrointestinal NETs. Information about their behavior and prognosis is reliant on small case series. This study set out to describe the population of patients who are diagnosed with ampullary NETs and compare them to patients with duodenal and pancreatic head NETs. Methods: The National Cancer Database (2004 – 2016) was queried for patients with ampullary, duodenal, and pancreatic head NETs. Clinicopathologic and treatment characteristics were compared. Subset analysis was performed on patients who underwent surgery. Kaplan Meier (KM) analysis and Cox regression were used to analyze the survival of patients with ampullary NETs. Results: Overall, 872 patients were identified with ampullary NET, 9692 with duodenal NET, and 6562 with pancreatic head NET. Patients with ampullary NET had an average age of 60.9 +/- 14.5 years, were evenly split among men and women (N = 437, 50.1% vs N = 435, 49.9%, respectively), and primarily Caucasian (N = 663, 76.0%). 72.1% underwent local tumor destruction or surgery (N = 629). Most did not receive radiation (N = 832, 95.4%), chemotherapy (N = 627, 71.9%), or hormone therapy (N = 788, 90.4%). Patients with ampullary NETs had more poorly differentiated tumors (N = 119, 13.6%) than patients with duodenal (N = 159, 1.6%) or pancreatic head (N = 602, 9.2%) NETs. Patients with ampullary NETs had more positive lymph nodes (N = 288, 33%) than patients with duodenal (N = 915, 9.4%) or pancreatic head (N = 1381, 21%) NETs. At five years, the overall survival for patients with ampullary, duodenal, and pancreatic head NETs was 57%, 68%, and 46%, respectively. Within the surgical population, five-year survival for patients with ampullary (N = 367), duodenal (N = 991), and pancreatic head (N = 1961) NETs was 60%, 74%, and 72%, respectively. When compared, there was a statistically significant difference between the mean overall survival of patients with ampullary (98 +/- 4.7 months), duodenal (112 +/- 2.5 months), and pancreatic head (108 +/- 1.7 months) NETs (p < 0.001). In the cox regression analysis, sex, Charlson-Deyo score, lymph node positivity, lymph-vascular invasion, mitotic rate, chromogranin A level, 5-HIAA level, and tumor size did not correlate with survival. Increasing age (HR 1.04, CI 1.01 – 1.07, p = 0.008) and worse tumor differentiation (poorly differentiated HR 3.33, CI 1.38 – 8.04, p = 0.008 and undifferentiated HR 8.31, CI 2.77 – 24.92, p < 0.001 compared to well differentiated) were associated with increased mortality. Conclusions: This study sheds light on a rare tumor histology. When compared to patients who underwent surgical resection for duodenal or pancreatic head NETs, patients with ampullary NETs had a significantly worse prognosis. Identifying prognostic factors allows us to create more concrete treatment recommendations and provide patients with improved prognostic information.

Aim. To access overall and event-free survival rates in patients after surgical treatment of localized and locally spread pancreatic head cancer. Materials and methods. A single center observational trial was conducted at a low-volume pancreatic surgery center in Khanty-Mansiysk. Data were collected retrospectively from 2007 to 2019. Patients with resectable tumors were included into the study whose final histology showed pancreatic ductal adenocarcinoma and en-bloc resection. According to the technical facilities and actual clinical protocols all patients received surgical treatment only and were then monitored. Data on progression patterns and survival rates were collected and calculated using Kaplan-Meier survival analysis. Results. Median overall survival (OS) after R0 pancreaticoduodenectomy was 16,8 months (IQR 10,9-23,5). Median progression-free survival was 10,6 mo. (IQR 8,0-20,7). OS in jaundiced patients was 4,9 mo. shorter than in patients without jaundice at the diagnosis (р = 0,011). Patients with serum bilirubin level < 100 μmol/l lived on average 7.2 months longer (p = 0.014). Most frequent sites of primary progression were liver and peritoneum, lungs, bones, lymph nodes of the abdominal cavity / retroperitoneal space, less often metastases were found in the skin and soft tissues. In 21.4% of cases metastases were found in several organs simultaneously with most frequent combination of liver and peritoneum, liver and lungs, lungs and bones. The median survival after progression was 7.1 ± 4.8 months Conclusion. Pancreatic duct adenocarcinoma has a high potential for progression and has therefore poor prognosis. To improve long-term outcomes, it is advisable to apply additional therapeutic options perioperatively.

Abstract Background Several studies have suggested a survival benefit of neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDAC) in the pancreatic head. Data concerning NAT for PDAC located in pancreatic body or tail are lacking. Methods Post hoc analysis of an international multicenter retrospective cohort of distal pancreatectomy for PDAC in 34 centers from 11 countries (2007–2015). Patients who underwent resection after NAT were matched (1:1 ratio), using propensity scores based on baseline characteristics, to patients who underwent upfront resection. Median overall survival was compared using the stratified log-rank test. Results Among 1236 patients, 136 (11.0%) received NAT, most frequently FOLFIRINOX (25.7%). In total, 94 patients receiving NAT were matched to 94 patients undergoing upfront resection. NAT was associated with less postoperative major morbidity (Clavien–Dindo ≥ 3a, 10.6% vs. 23.4%, P = 0.020) and pancreatic fistula grade B/C (9.6% vs. 21.3%, P = 0.026). NAT did not improve overall survival [27 (95% CI 14–39) versus 31 months (95% CI 19–42), P = 0.277], as compared with upfront resection. In a sensitivity analysis of 251 patients with radiographic tumor involvement of splenic vessels, NAT (n = 37, 14.7%) was associated with prolonged overall survival [36 (95% CI 18–53) versus 20 months (95% CI 15–24), P = 0.049], as compared with upfront resection. Conclusion In this international multicenter cohort study, NAT for resected PDAC in pancreatic body or tail was associated with less morbidity and pancreatic fistula but similar overall survival in comparison with upfront resection. Prospective studies should confirm a survival benefit of NAT in patients with PDAC and splenic vessel involvement.

Objective This study was performed to explore the relationship between various clinical factors and the prognosis of limb osteosarcoma. Methods We retrospectively analyzed the clinical data of 336 patients with limb osteosarcoma treated from June 2000 to August 2016 at 7 Chinese cancer centers. Data on the patients’ clinical condition, treatment method, complications, recurrences, metastasis, and prognosis were collected and analyzed. Kaplan–Meier analysis and Cox regression models were used to analyze the data. Results The patients comprised 204 males and 132 females ranging in age from 6 to 74 years (average, 21.1 years). The overall 3- and 5-year survival rates were 65.0% and 55.0%, respectively. The 5-year overall survival rate was 64.0% with standard chemotherapy and 45.6% with non-standard chemotherapy. Cox regression analysis demonstrated that standard chemotherapy, surgery, recurrence, and metastasis were independent factors associated with the prognosis of limb osteosarcoma. Conclusion The survival of patients with limb osteosarcoma can be significantly improved by combining standard chemotherapy and surgery. The overall survival rate can also be improved by adding methotrexate to doxorubicin–cisplatin–ifosfamide triple chemotherapy.

Phaeochromocytomas (PHEO) and paragangliomas are rare catecholamine-producing tumours. Although 10–30% of these tumours metastasise, histopathological criteria to discriminate malignant from benign tumours have not been established; therefore, reliable histopathological markers predicting metastasis are urgently required. A total of 163 tumours, including 40 metastatic tumours, collected by the Phaeochromocytoma Study Group in Japan (PHEO-J) were analysed using a system called grading system for adrenal phaeochromocytoma and paraganglioma (GAPP). The tumours were scored based on GAPP criteria as follows: histological pattern, cellularity, comedo-type necrosis, capsular/vascular invasion, Ki67 labelling index and catecholamine type. All tumours were scored from 0 to 10 points and were graded as one of the three types: well-differentiated (WD, 0–2 points), moderately differentiated (MD, 3–6 points) and poorly differentiated (PD, 7–10 points). GAPP scores of the non-metastatic and metastatic groups were 2.08±0.17 and 5.33±0.43 (mean±s.e.m., P<0.001) respectively. There was a significant negative correlation between the GAPP score and the interval until metastasis (r=−0.438, P<0.01). The mean number of years until metastasis after the initial operation was 5.5±2.6 years. The study included 111 WD, 35 MD and 17 PD types. The five-year survival of these groups was 100, 66.8 and 22.4% respectively. In addition, negative immunoreactivity for succinate dehydrogenase gene subunit B (SDHB) was observed in 13 (8%) MD or PD tumours and ten of the 13 (77%) had metastases. Our data indicate that a combination of GAPP classification and SDHB immunohistochemistry might be useful for the prediction of metastasis in these tumours.

181 Background: To compare the efficacy of docetaxel plus FOLFOX4 to FOLFOX4 as adjuvant chemotherapy for gastric cancer patients. Methods: 320 patients with stage IB-IV (M0) gastric cancer were enrolled into the retrospective study. All patients received a total or subtotal gastrectomy with at least D1 lymph nodes dissection. 193 patients received FOLFOX4 as adjuvant chemotherapy. 127 patients received biweekly docetaxel plus FOLFOX4 (DOF regimen) as adjuvant chemotherapy. Docetaxel was administered at 40 mg/m2 on day 1, followed by FOLFOX4 regimen. Both of the regimens were repeated every 2 weeks for a maximum of 12 cycles. Results: In comparison with patients in FOLFOX4 group, patients in DOF group were relatively younger (p=.001), with more advanced disease in pN stage (p=.035) and pTNM stage (p=.031), received more cycles of adjuvant chemotherapy (p=.004), and had a higher percentage of adjuvant radiation (p =.002). After adjustment of unbalanced variables as mentioned above, no statistical difference was observed between DOF group and FOLFOX4 group in terms of 3-year disease-free survival (54% vs 69%, p = 0.100, HR 1.362, 95% CI (0.943-1.967)) and 3-year overall survival(70% vs 72%, p = 0.810, HR 1.049, 95% CI (0.711-1.548)). Stratified analysis according to clinicopathologic characters showed that there were almost no statistical differences of 3-year overall survival rates between two groups, except the primary site (middle 1/3) (p =.025) and pTNM stage (IIb stage) (p =.035) in favor of FOLFOX4 group. The incidences of grade 3/4 adverse events were obviously higher in DOF group than in FOLFOX4 group,including decreased appetite (18.1% V 10.4%, P = 0.046), diarrhea (4.7% V 0%, p=0.004 ), hypersensitivity reactions to oxaliplatin (3.1% V 0%, p=0.024) and neutropenia (47.3% V 31.6%, p=0.004). Conclusions: Compared to FOLFOX4 regimen, adjuvant docetaxel plus FOLFOX4 did not show significant survival advantages in gastric cancer patients. However, a more serious toxicity profile was observed in docetaxel plus FOLFOX4 arm. Further studies are needed to decide whether triplet regimen is appropriate as adjuvant chemotherapy of gastric cancer.

New Surgical Technique

For pancreatic ductal adenocarcinoma (PDAC) of the head and/or body invading the splenic artery (SA), we developed a new surgical technique of proximal subtotal pancreatectomy with splenic artery and vein resection, so-called pancreaticoduodenectomy with splenic artery resection (PD-SAR). We retrospectively reviewed a total of 84 patients with curative intent pancreaticoduodenectomy (PD) for PDAC of the head and/or body. These 84 patients were classified into the two groups: conventional PD (n=66) and PD-SAR (n=18). Most patients were treated by preoperative chemoradiotherapy (CRT). Postoperative MDCT clearly demonstrated enhancement of the remnant pancreas at 1 and 6 months in all patients examined. Overall survival rates were very similar between PD and PD-SAR (3-year OS: 23.7% versus 23.1%,P=0.538), despite the fact that the tumor size and the percentages of UICC-T4 determined before treatment were higher in PD-SAR. Total daily insulin dose was significantly higher in PD-SAR than in PD at 1 month, while showing no significant differences between the two groups thereafter. PD-SAR with preoperative CRT seems to be promising surgical strategy for PDAC of head and/or body with invasion of the splenic artery, in regard to the balance between operative radicality and postoperative QOL.
