RESUMEN
This multicenter, randomized phase II/III study evaluated the addition of the vascular endothelial growth factor receptor-2 inhibitor ramucirumab to FLOT as perioperative treatment for resectable esophagogastric adenocarcinoma. Patients received either FLOT alone (Arm A) or combined with ramucirumab followed by ramucirumab monotherapy (Arm B). The primary endpoint for the phase II portion was the pathological complete or subtotal response (pCR/pSR) rate. Baseline characteristics were comparable between both arms with a high rate of tumors signet-ring cell component (A:47% B:43%). No between-arm difference in pCR/pSR rate was seen (A:29% B:26%), therefore the transition to phase III was not pursued. Nevertheless, the combination was associated with a significantly increased R0-resection rate compared with FLOT alone (A:82% B:96%; P = .009). In addition, the median disease-free survival was numerically improved in Arm B (A:21 months B:32 months, HR 0.75, P = 0.218), while the median overall survival was similar in both treatment arms (A:45 months B:46 months, HR 0.94, P = 0.803). Patients with Siewert type I tumors receiving transthoracic esophagectomy with intrathoracic anastomosis showed an increased risk of serious postoperative complications after ramucirumab treatment, therefore recruitment of those patients was stopped after the first-third of the study. Overall, surgical morbidity and mortality was comparable, whereas more non-surgical grade ≥ 3 adverse events were observed with the combination, especially anorexia (A:1% B:11%), hypertension (A:4% B:13%) and infections (A:19% B:33%). The combination of ramucirumab and FLOT as perioperative treatment shows efficacy signals, particularly in terms of R0 resection rates, for a study population with a high proportion of prognostically poor histological subtypes, and further evaluation in this subgroup seems warranted.

INTRODUCTION: This is a single-arm study (NCT01956149) to determine the prolonged (≥ 4 months) disease control rate with cabazitaxel administered in second-(or later) setting for patients with advanced or metastatic adenocarcinoma of the esophagogastric junction (EGJ) and stomach. METHODS: 65 patients with advanced EGJ and stomach cancer were treated with 20 mg/m2 cabazitaxel every 3 weeks for a maximum of six cycles. The main objective of the study is a prolonged disease control rate (pDCR: CR, PR or SD lasting at least 4 months). Secondary outcome measures were overall survival, progression-free survival, response rate by subgroup (with vs without previous treatment with a taxane) and toxicity. Patients were assessed for tumor response every 6 weeks during therapy and during the follow-up (up to 12 months). RESULTS: 65 patients (median age: 63, range 31-86 years) were assigned to treatment. Median no. of prior therapies that had received prior taxane therapy was 2. 80%. Patients received a median of two cycles of cabazitaxel. Efficacy results are for the ITT population. The mDCR in n = 65 patients was 10.8% (95% CI 4.4-20.9%). There was a control of disease (CR + PR + SD) in n = 26 patients of n = 65, corresponding to a DCR of 40.0% (95% CI 28.0-52.9%). In patients without prior taxane use, it was 46.2% (95% CI 25.1-80.8%) and in patients with only one prior therapy, DCR was 50.0% (95% CI 31.3-68.7%). The median overall survival was 4.6 months (95% CI 3.16, 5.59) in the whole ITT population. In patients with only one prior therapy, median OS was 5.4 months (95% CI 2.60, 7.43) and in patients without taxane pretreatment, it was 6.4 months (95% CI 1.38, 14.17). The median progression-free survival time was 1.5 months (95% CI 1.32, 2.27) in the whole ITT population, 2.9 months (95% CI 0.72, 4.67) without prior taxane therapy and was 1.7 (95% CI 1.28, 3.35) months in patients with only one prior therapy median. CONCLUSIONS: Cabazitaxel is active in heavily pretreated patients with metastatic and advanced esophagogastric junction and gastric adenocarcinoma. Efficacy results in a classic second-line population are comparable to other second-line studies, therefore, under the limitations of this trial, (single arm, Phase II design) cabazitaxel might be an option especially in patients without prior taxane therapy, in second line and even further line therapy of metastatic and advanced esophagogastric junction and gastric adenocarcinoma.

BACKGROUND: Historical data indicate that surgical resection may benefit select patients with metastatic gastric and gastroesophageal junction cancer. However, randomized clinical trials are lacking. The current RENAISSANCE trial addresses the potential benefits of surgical intervention in gastric and gastroesophageal junction cancer with limited metastases. METHODS: This is a prospective, multicenter, randomized, investigator-initiated phase III trial. Previously untreated patients with limited metastatic stage (retroperitoneal lymph node metastases only or a maximum of one incurable organ site that is potentially resectable or locally controllable with or without retroperitoneal lymph nodes) receive 4 cycles of FLOT chemotherapy alone or with trastuzumab if Her2+. Patients without disease progression after 4 cycles are randomized 1:1 to receive additional chemotherapy cycles or surgical resection of primary and metastases followed by subsequent chemotherapy. 271 patients are to be allocated to the trial, of which at least 176 patients will proceed to randomization. The primary endpoint is overall survival; main secondary endpoints are quality of life assessed by EORTC-QLQ-C30 questionnaire, progression free survival and surgical morbidity and mortality. Recruitment has already started; currently (Feb 2017) 22 patients have been enrolled. DISCUSSION: If the RENAISSANCE concept proves to be effective, this could potentially lead to a new standard of therapy. On the contrary, if the outcome is negative, patients with gastric or GEJ cancer and metastases will no longer be considered candidates for surgical intervention. TRIAL REGISTRATION: The article reports of a health care intervention on human participants and is registered on October 12, 2015 under ClinicalTrials.gov Identifier: NCT02578368 ; EudraCT: 2014-002665-30.

IMPORTANCE: Surgical resection has a potential benefit for patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction. OBJECTIVE: To evaluate outcome in patients with limited metastatic disease who receive chemotherapy first and proceed to surgical resection. DESIGN, SETTING, AND PARTICIPANTS: The AIO-FLOT3 (Arbeitsgemeinschaft Internistische Onkologie-fluorouracil, leucovorin, oxaliplatin, and docetaxel) trial is a prospective, phase 2 trial of 252 patients with resectable or metastatic gastric or gastroesophageal junction adenocarcinoma. Patients were enrolled from 52 cancer care centers in Germany between February 1, 2009, and January 31, 2010, and stratified to 1 of 3 groups: resectable (arm A), limited metastatic (arm B), or extensive metastatic (arm C). Data cutoff was January 2012, and the analysis was performed in March 2013. INTERVENTIONS: Patients in arm A received 4 preoperative cycles of fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) followed by surgery and 4 postoperative cycles. Patients in arm B received at least 4 cycles of neoadjuvant FLOT and proceeded to surgical resection if restaging (using computed tomography and magnetic resonance imaging) showed a chance of margin-free (R0) resection of the primary tumor and at least a macroscopic complete resection of the metastatic lesions. Patients in arm C were offered FLOT chemotherapy and surgery only if required for palliation. Patients received a median (range) of 8 (1-15) cycles of FLOT. MAIN OUTCOMES AND MEASURES: The primary end point was overall survival. RESULTS: In total, 238 of 252 patients (94.4%) were eligible to participate. The median (range) age of participants was 66 (36-79) years in arm A (n = 51), 63 (28-79) years in arm B (n = 60), and 65 (23-83) years in arm C (n = 127). Patients in arm B (n = 60) had only retroperitoneal lymph node involvement (27 patients [45%]), liver involvement (11 [18.3%]), lung involvement (10 [16.7%]), localized peritoneal involvement (4 [6.7%]), or other (8 [13.3%]) incurable sites. Median overall survival was 22.9 months (95% CI, 16.5 to upper level not achieved) for arm B, compared with 10.7 months (95% CI, 9.1-12.8) for arm C (hazard ratio, 0.37; 95% CI, 0.25-0.55) (P < .001). The response rate for arm B was 60% (complete, 10%; partial, 50%), which is higher than the 43.3% for arm C. In arm B, 36 of 60 patients (60%) proceeded to surgery. The median overall survival was 31.3 months (95% CI, 18.9-upper level not achieved) for patients who proceeded to surgery and 15.9 months (95% CI, 7.1-22.9) for the other patients. CONCLUSIONS AND RELEVANCE: Patients with limited metastatic disease who received neoadjuvant chemotherapy and proceeded to surgery showed a favorable survival. The AIO-FLOT3 trial provides a rationale for further randomized clinical trials. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT00849615.

BACKGROUND: Over the past two decades, there has been a rising trend in malignant melanoma incidence worldwide. In 2008, Germany introduced a nationwide skin cancer screening program starting at age 35. The aims of this study were to analyse the distribution of malignant melanoma tumour stages over time, as well as demographic and regional differences in stage distribution and survival of melanoma patients. METHODS: Pooled data from 61 895 malignant melanoma patients diagnosed between 2002 and 2011 and documented in 28 German population-based and hospital-based clinical cancer registries were analysed using descriptive methods, joinpoint regression, logistic regression and relative survival. RESULTS: The number of annually documented cases increased by 53.2% between 2002 (N = 4 779) and 2011 (N = 7 320). There was a statistically significant continuous positive trend in the proportion of stage UICC I cases diagnosed between 2002 and 2011, compared to a negative trend for stage UICC II. No trends were found for stages UICC III and IV respectively. Age (OR 0.97, 95% CI 0.97-0.97), sex (OR 1.18, 95% CI 1.11-1.25), date of diagnosis (OR 1.05, 95% CI 1.04-1.06), 'diagnosis during screening' (OR 3.24, 95% CI 2.50-4.19) and place of residence (OR 1.23, 95% CI 1.16-1.30) had a statistically significant influence on the tumour stage at diagnosis. The overall 5-year relative survival for invasive cases was 83.4% (95% CI 82.8-83.9%). CONCLUSIONS: No distinct changes in the distribution of malignant melanoma tumour stages among those aged 35 and older were seen that could be directly attributed to the introduction of skin cancer screening in 2008.

BACKGROUND: Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma, but has not yet been evaluated in the context of resectable patients. Here we report findings from the phase 2 part of the phase 2/3 FLOT4 trial, which compared histopathological regression in patients treated with a docetaxel-based triplet chemotherapy versus an anthracycline-based triplet chemotherapy before surgical resection. METHODS: In this randomised, open-label, phase 2/3 study, eligible participants were recruited from 28 German oncology centres. Patients with resectable gastric or gastro-oesophageal junction cancer who had clinical stage cT2 or higher, nodal positive (cN+) disease, or both were randomly assigned (1:1) to either three preoperative and three postoperative 3-week cycles of intravenous epirubicin 50 mg/m2 on day 1, intravenous cisplatin 60 mg/m2 on day 1, and either fluorouracil 200 mg/m2 as continuous intravenous infusion or capecitabine 1250 mg/m2 orally (two doses of 625 mg/m2 per day) on days 1 to 21 (ECF/ECX group) or four preoperative and four postoperative 2-week cycles of docetaxel 50 mg/m2, intravenous oxaliplatin 85 mg/m2, intravenous leucovorin 200 mg/m2, and fluorouracil 2600 mg/m2 as a 24 h infusion, all on day 1 (FLOT group). Randomisation was done centrally with an interactive web-response system based on a sequence generated with blocks (block size 2) stratified by Eastern Cooperative Oncology Group performance status, location of primary tumour, age, and nodal status. No masking was done. Central assessment of pathological regression was done according to the Becker criteria. The primary endpoint was pathological complete regression (tumour regression grade TRG1a) and was analysed in the modified intention-to-treat population, defined as all patients who were randomly assigned to treatment excluding patients who had surgery but did not provide resection specimens for central evaluation. The study (including the phase 3 part) has completed enrolment, but follow-up is ongoing and this is an interim analysis. The trial is registered with ClinicalTrials.gov, number NCT01216644. FINDINGS: Between Aug 18, 2010, and Aug 10, 2012, 300 patients (152 patients in the ECF/ECX group; 148 patients in the FLOT group) were enrolled into the phase 2 part of the study, 265 of whom (137 in the ECF/ECX group; 128 in the FLOT group) were assessable on a modified intention-to-treat basis. 119 (93%) of 128 patients in the FLOT group and 126 (92%) of 137 patients in the ECF/ECX group were given all planned preoperative cycles of treatment. FLOT was associated with significantly higher proportions of patients achieving pathological complete regression than was ECF/ECX (20 [16%; 95% CI 10-23] of 128 patients vs eight [6%; 3-11] of 137 patients; p=0·02). 44 (40%) of 111 patients in the ECF/ECX group and 30 (25%) of 119 patients in the FLOT group had at least one serious adverse event involving a perioperative medical or surgical complication. The most common non-surgical grade 3-4 adverse events were neutropenia (52 [38%] of 137 patients in the ECF/ECX group vs 67 [52%] of 128 patients in the FLOT group), leucopenia (28 [20%] vs 36 [28%]), nausea (23 [17%] vs 12 [9%]), infection (16 [12%] vs 15 [12%]), fatigue (19 [14%] vs 11 [9%]), and vomiting (13 [10%] vs four [3%]). INTERPRETATION: Perioperative FLOT was active and feasible to administer, and might represent an option for patients with locally advanced, resectable gastric or gastro-eosophageal junction adenocarcinoma. FUNDING: None.

BACKGROUND: The prognostic role of circulating tumor cells (CTCs) after induction chemotherapy using docetaxel, cisplatin and fluorouracil (TPF) prior to surgery and adjuvant (chemo)radiation in locally advanced oral squamous cell cancer (OSCC) was evaluated. METHODS: In this prospective study, peripheral blood samples from 40 patients of the phase II study TISOC-1 (NCT01108042) with OSCC before, during, and after treatment were taken. CTCs were quantified using laser scanning cytometry of anti- epithelial cell adhesion molecule-stained epithelial cells. Their detection was correlated with clinical risk factors, recurrence-free (RFS) and overall survival (OS). RESULTS: Before starting the treatment CTCs were detected in 32 of 40 patients (80%). The median number at baseline was 3295 CTCs/ml. The median maximal number of CTCs during treatment was 5005 CTCs/ml. There was a significant increase of CTCs before postoperative radiotherapy compared to baseline before 1st cycle of IC (p = 0.011), 2nd cycle of IC (p = 0.001), 3rd cycle of IC (p = 0.004), and before surgery (p = 0.002), but not compared to end of therapy (p = 0.118). CTCs at baseline >median was also associated to risk of recurrence (p = 0.014). Maximal CTCs during therapy >median was more frequently observed in tumors of the oral cavity (p=0.022) and related to higher risk of death during follow-up (p = 0.028). Patients with CTCs at baseline >median value had significant lower RFS than patients with CTCs at baseline Asunto(s)

RESUMEN
PURPOSE: The objective of this study was to examine patterns of care and survival in a population-based sample of patients with parotid cancer who were treated in Thuringia, a federal state in Germany, between 1996 and 2011. METHODS: Data of 295 patients with primary parotid cancer from the Thuringian cancer registry were evaluated for patient's characteristics, tumor stage, incidence, and trends in treatment, cancer-specific survival (CSS), and overall survival (OS). RESULTS: Stages IV tumors and the amount of tumors in all age cohorts ≥45 years of age increased significantly during the observation period (p = 0.002; age all p < 0.05, respectively). The highest increase in crude incidence was observed for salivary duct carcinomas [relative risk per decade (RR) 5.46; 95% confidence interval (CI) 1.14-26.14] and rare carcinoma subtypes (RR 9.99; 95% CI 1.85-53.94). CSS at 5 years and at 10 years for all patients was 82.4 and 82.4%, respectively. OS at 5 years and at 10 years for all patients was 60.1 and 48.2%, respectively. CSS and OS did not improve over the time. Salivary duct carcinoma showed the lowest 5-year OS (35.6%). Acinic cell carcinoma had the highest OS rate (85.3%). Multivariate Cox models revealed that higher grading (G3/G4) was a more powerful independent predictor of decreased OS than TNM stage. CONCLUSIONS: CSS and OS did not improve during the study period. Incidence of parotid cancer increased significantly in elderly patients. It seems that grading is next to patient's age the better predictor of OS than TNM stage.

INTRODUCTION: The objective of this study was to examine patterns of care and survival in a population-based sample of patients with head neck cancer (HNC) who were treated in Thuringia, a federal state in Germany, between 1996 and 2011. METHODS: Data of 6291 patients with primary HNC from the Thuringian cancer registry were used to evaluate for patient's characteristics, tumor stage, incidence, and trends in treatment and overall survival (OS). RESULTS: The distribution between stages I-IV did not change significantly during the observation period. Crude incidences of HNC increased significantly between 1996 and 2011 from 13.77 to 20.39 (relative risk [RR]=1.34; 95% confidence interval [CI]=1.25-1.45). This increase was mainly driven by a significant increase of oropharynx cancer (from 3.29 to 5.85; RR=1.67; 95%CI=1.49-1.88) and cancer of the oral cavity (3.41-5.90; RR=1.5; 95%CI=1.33-1.69). The relative frequency of multimodal therapy increased (RR=1.42; 95%CI=1.3-1.55). The use of cetuximab increased (RR=473.32; 95%CI=51.57-4344.51). The 5-year and 10-year OS for the entire cohort was 49.1% and 34.1%, respectively. The multivariable analysis has proven that male gender, age ⩾60years, therapy without surgery, and TNM stage were independent significant negative risk factors for OS (all p<0.0001). CONCLUSIONS: OS did not improve during the study period. Incidence of oral cancer is significantly increasing. Although modern treatment strategies have been included in routine HNC care over the time, outcome has not improved significantly.

BACKGROUND: Combination of fluoropyrimidines and a platinum derivative are currently standards for systemic chemotherapy in advanced adenocarcinoma of the stomach and gastroesophageal junction (GEJ). Nevertheless, individual likelihood for response to these therapeutic regimes remains uncertain. Even more, no predictive markers are available to determine which patients may benefit more from oxaliplatin versus cisplatin or vice versa. The new invasion and stem cell markers VEGFR-3 and CXCR4 have been linked prognostically with more aggressive esophagogastric cancer types. Thus, we aimed to assess correlations of VEGFR-3 and CXCR4 expression levels with clinical outcome in a randomized phase III study of patients with oxaliplatin/leucovorin/5-FU (FLO) versus cisplatin/leucovorin/5-FU (FLP). METHODS: The patients data examined in this study (n = 72) were from the collective of the FLO vs. FLP phase III AIO trial. Tumour tissues were stained via immunohistochemistry for VEGFR-3 and CXCR4 expression and results were evaluated by two independent, blinded investigators.Outcome parameter: Survival analysis was calculated for patients receiving FLO vs. FLP in relation to VEGFR-3 and CXCR4 expression. RESULTS: 54% and 36% of the examined tumour tissues showed strong positive expression of VEGFR-3 and CXCR4 respectively. No superiority of each regime was detected in terms of overall survival (OS) in the whole population. Patients with strong expression of CXCR4 on their tumour tissues profited more in terms of OS under the treatment of FLP (mOS: 28 vs 15 months, p = 0.05 respectively). Patients with negative VEGFR-3 and CXCR4 expression had a trend to live longer when FLO regime was applied (mOS: 22 vs. 9 months, p = 0.099 and 20 vs. 10 months, p = 0.073 respectively). In an exploratory analysis of patients older than 60 years at diagnosis, we observed a significant benefit in overall survival for VEGFR-3 and CXCR4-positive patients when treated with FLP (p = 0.002, p = 0.021 respectively). CONCLUSIONS: CXCR4 positive patients profited in terms of OS from FLP, whereas FLO proved to be more effective in CXCR4 and VEGFR-3 negative patients. Our results suggest, despite the limited size of the study, a predictive value of these biomarkers concerning chemotherapy with FLP or FLO in advanced esophagogastric cancer.

The purpose of this study was to analyze the impact of tumor volume (TV) measurements as prognosticator for recurrence-free survival (RFS) and overall survival (OS) from data of head and neck cancer (HNC) registries. TV measurements were performed in pre-treatment computed tomography (CT) or magnetic resonance images (MRI) of 392 unselected HNC patients. TV measurements were feasible in 275 patients (70 %). Median CT TV and MRI TV were 11.43 and 10.4 cm(3), respectively. The CT TV was significantly different only between T1 and T4. CT TV was significantly different only between T1 and T4 (p = 0.041). MRI TV was significantly different between T1 and T4 (p = 0.003) as well as between T2 and T4 (p = 0.002). Median follow-up was 26.1 months. Median RFS was 80.7 months. Median OS was 66.5 months. On univariate analysis, significant prognostic factors for decreased RFS were advanced T stage (p = 0.010); M1 (p = 0.001) and an MRI TV > 10.4 cm(3) (p = 0.001). Significant prognostic factors for a decreased OS were advanced T stage (p = 0.001), N+ (p = 0 006), M+ (p < 0.001), tumor recurrence (p < 0.001), CT TV (p = 0.005), and MRI TV (p = 0.012). On multivariate analysis for RFS, MRI TV was the best independent prognosticator (p = 0.003). On multivariate analysis for OS, T stage (p = 0.006) was a better prognosticator than CT or MRI TV. Using CT and MRI data sets of an unselected series of HNC patients in a cancer registry, TV measurements were not feasible in all patients. MRT TV was a powerful prognosticator for RFS.

BACKGROUND: Induction chemotherapy (ICT) with docetaxel, cisplatin and fluorouracil (TPF) followed by radiotherapy is an effective treatment option for unresectable locally advanced head and neck cancer. This phase I study was designed to investigate the safety and tolerability of a split-dose TPF ICT regimen prior to surgery for locally advanced resectable oral and oropharyngeal cancer. METHODS: Patients received TPF split on two dosages on day 1 and 8 per cycle for one or three 3-week cycles prior to surgery and postoperative radiotherapy or radiochemotherapy. Docetaxel was escalated in two dose levels, 40 mg/m2 (DL 0) and 30 mg/m2 (DL -1), plus 40 mg/m2 cisplatin and 2000 mg/m2 fluorouracil per week using a 3 +3 dose escalation algorithm. RESULTS: Eighteen patients were enrolled and were eligible for toxicity and response. A maximum tolerated dose of 30 mg/m2 docetaxel per week was reached. The most common grade 3+ adverse event was neutropenia during ICT in 10 patients. Surgery reached R0 resection in all cases. Nine patients (50%) showed complete pathologic regression. CONCLUSIONS: A split-dose regime of TPF prior to surgery is feasible, tolerated and merits additional investigation in a phase II study with a dose of 30 mg/m docetaxel per week.

PURPOSE: This study was designed to compare fluorouracil, leucovorin, and oxaliplatin with fluorouracil, leucovorin, and cisplatin in patients with advanced gastric cancer. PATIENTS AND METHODS: Patients with previously untreated advanced adenocarcinoma of the stomach or esophagogastric junction were randomly assigned to receive either fluorouracil 2,600 mg/m(2) via 24-hour infusion, leucovorin 200 mg/m(2), and oxaliplatin 85 mg/m(2) (FLO) every 2 weeks or fluorouracil 2,000 mg/m(2) via 24-hour infusion, leucovorin 200 mg/m(2) weekly, and cisplatin 50 mg/m(2) every 2 weeks (FLP). The primary end point was progression-free survival (PFS). RESULTS: Two hundred twenty patients (median age, 64 years; metastatic, 94%) were randomly assigned. FLO was associated with significantly less (any grade) anemia (54% v 72%), nausea (53% v 70%), vomiting (31% v 52%), alopecia (22% v 39%), fatigue (19% v 34%), renal toxicity (11% v 34%), thromboembolic events (0.9% v 7.8%), and serious adverse events related to the treatment (9% v 19%). FLP was associated with significantly less peripheral neuropathy (22% v 63%). There was a trend toward improved median PFS with FLO versus FLP (5.8 v 3.9 months, respectively; P = .077) and no significant difference in median overall survival (10.7 v 8.8 months, respectively). However, in patients older than 65 years (n = 94), treatment with FLO resulted in significantly superior response rates (41.3% v 16.7%; P = .012), time to treatment failure (5.4 v 2.3 months; P < .001), and PFS (6.0 v 3.1 month; P = .029) and an improved OS (13.9 v 7.2 months) as compared with FLP, respectively. CONCLUSION: FLO reduced toxicity as compared with FLP. In older adult patients, FLO also seemed to be associated with improved efficacy.

CONTEXT: The role of adjuvant therapy in resectable pancreatic cancer is still uncertain, and no recommended standard exists. OBJECTIVE: To test the hypothesis that adjuvant chemotherapy with gemcitabine administered after complete resection of pancreatic cancer improves disease-free survival by 6 months or more. DESIGN, SETTING, AND PATIENTS: Open, multicenter, randomized controlled phase 3 trial with stratification for resection, tumor, and node status. Conducted from July 1998 to December 2004 in the outpatient setting at 88 academic and community-based oncology centers in Germany and Austria. A total of 368 patients with gross complete (R0 or R1) resection of pancreatic cancer and no prior radiation or chemotherapy were enrolled into 2 groups. INTERVENTION: Patients received adjuvant chemotherapy with 6 cycles of gemcitabine on days 1, 8, and 15 every 4 weeks (n = 179), or observation ([control] n = 175). MAIN OUTCOME MEASURES: Primary end point was disease-free survival, and secondary end points were overall survival, toxicity, and quality of life. Survival analysis was based on all eligible patients (intention-to-treat). RESULTS: More than 80% of patients had R0 resection. The median number of chemotherapy cycles in the gemcitabine group was 6 (range, 0-6). Grade 3 or 4 toxicities rarely occurred with no difference in quality of life (by Spitzer index) between groups. During median follow-up of 53 months, 133 patients (74%) in the gemcitabine group and 161 patients (92%) in the control group developed recurrent disease. Median disease-free survival was 13.4 months in the gemcitabine group (95% confidence interval, 11.4-15.3) and 6.9 months in the control group (95% confidence interval, 6.1-7.8; P<.001, log-rank). Estimated disease-free survival at 3 and 5 years was 23.5% and 16.5% in the gemcitabine group, and 7.5% and 5.5% in the control group, respectively. Subgroup analyses showed that the effect of gemcitabine on disease-free survival was significant in patients with either R0 or R1 resection. There was no difference in overall survival between the gemcitabine group (median, 22.1 months; 95% confidence interval, 18.4-25.8; estimated survival, 34% at 3 years and 22.5% at 5 years) and the control group (median, 20.2 months; 95% confidence interval, 17-23.4; estimated survival, 20.5% at 3 years and 11.5% at 5 years; P = .06, log-rank). CONCLUSIONS: Postoperative gemcitabine significantly delayed the development of recurrent disease after complete resection of pancreatic cancer compared with observation alone. These results support the use of gemcitabine as adjuvant chemotherapy in resectable carcinoma of the pancreas. TRIAL REGISTRATION: isrctn.org Identifier: ISRCTN34802808.
