PURPOSE ADJUVANT-CTONG1104 (ClinicalTrials.gov identifier: NCT01405079 ), a randomized phase III trial, showed that adjuvant gefitinib treatment significantly improved disease-free survival (DFS) versus vinorelbine plus cisplatin (VP) in patients with epidermal growth factor receptor ( EGFR) mutation-positive resected stage II-IIIA (N1-N2) non–small-cell lung cancer (NSCLC). Here, we report the final overall survival (OS) results. METHODS From September 2011 to April 2014, 222 patients from 27 sites were randomly assigned 1:1 to adjuvant gefitinib (n = 111) or VP (n = 111). Patients with resected stage II-IIIA (N1-N2) NSCLC and EGFR-activating mutation were enrolled, receiving gefitinib for 24 months or VP every 3 weeks for four cycles. The primary end point was DFS (intention-to-treat [ITT] population). Secondary end points included OS, 3-, 5-year (y) DFS rates, and 5-year OS rate. Post hoc analysis was conducted for subsequent therapy data. RESULTS Median follow-up was 80.0 months. Median OS (ITT) was 75.5 and 62.8 months with gefitinib and VP, respectively (hazard ratio [HR], 0.92; 95% CI, 0.62 to 1.36; P = .674); respective 5-year OS rates were 53.2% and 51.2% ( P = .784). Subsequent therapy was administered upon progression in 68.4% and 73.6% of patients receiving gefitinib and VP, respectively. Subsequent targeted therapy contributed most to OS (HR, 0.23; 95% CI, 0.14 to 0.38) compared with no subsequent therapy. Updated 3y DFS rates were 39.6% and 32. 5% with gefitinib and VP ( P = .316) and 5y DFS rates were 22. 6% and 23.2% ( P = .928), respectively. CONCLUSION Adjuvant therapy with gefitinib in patients with early-stage NSCLC and EGFR mutation demonstrated improved DFS over standard of care chemotherapy. Although this DFS advantage did not translate to a significant OS difference, OS with adjuvant gefitinib was one of the longest observed in this patient group compared with historic data.

9005 Background: ADJUVANT-CTONG1104, a randomized phase 3 trial showed adjuvant gefitinib treatment significantly improved disease-free survival (DFS) vs standard doublet chemotherapy in patients (pts) with epidermal growth factor receptor ( EGFR) mutation-positive resected stage II-IIIA (N1-N2) non-small-cell lung cancer (NSCLC). 5-year survival rate of N1N2 were 38%-50% in IASLC staging system. Here, we present the final overall survival (OS) results from the study. Methods: From Sep 2011 to April 2014, 222 patients, aged 18-75 years, with EGFR activating mutation through completely resection and diagnosed as stage II-IIIA (N1-N2) NSCLC pathologically from 27 sites were enrolled. The enrolled patients were 1:1 randomized to receive adjuvant gefitinib (250 mg once per day) for 24 months (G, n=111) or vinorelbine (25 mg/m2, d1 and d8) plus cisplatin (75 mg/m2, d1) every 3 weeks for 4 cycles (C, n=111). The primary endpoint was DFS in the ITT population. Secondary endpoints included OS, 3 and 5-year DFS rate, 5-year OS rate. The subsequent therapy data were collected, including crossover from C to G, re-challenge TKI and other treatment. Data cut-off date was Jan. 13, 2020. Results: A median follow-up was 76.9 months. The median OS (mOS) was 75.5 months based on 95 (42.8%) events in ITT whole population. The mOS was 75.5m in G arm and 79.2m in C arm (HR 0.96, 95%CI 0.64-1.43, p=0.823). The 3, 5-year OS rate were 68.6%, 53.8% in G and 67.5%, 52.4% in C respectively. DFS in 3, 5-y were 40.3%, 23.4% in G and 33.2%, 23.7% in C, respectively (P3-y=0.395, P5-y=891). All predefined subgroups including age, gender, lymph node, EGFR mutation type had no significant difference in statistics but in favor of G arm in trend. Subsequent treatment especially targeted therapy contributed most to OS (HR = 0.46, 95% CI 0.26 – 0.83). Median OS of patients receiving subsequent target therapy was75.5m (n=35), 36.4m in other treatment (n=33; (P<0.001). For G mOS were 75.5 (n=15; target therapy) and 35.0 (n=18; other, p<0.001), for C 62.8m (n=20) and 46.8m (n=15; p=0.251). The RR was 26.7%, DCR 66.7%, mPFS 14.1m and mOS 19.6m for patients with rechallenged EGFR TKI in G arm (n=15). No novel unexpected SAE was observed during follow up. Conclusion The DFS survival advantage did not translate to OS difference in ADJUVANT trial. The OS with 75.5m was the best one of survival in completely resected N1N2 NSCLC comparing with historical data and sequent TKI treatment contribute to overall survival. Clinical trial information: NCT01405079.

7010 Background: Cancers with activating EGFR mutations are exquisitely sensitive to EGFR tyrosine kinase inhibitors (TKIs) and retrospective data suggests adjuvant TKIs may improve outcomes in EGFR mutants. This prospective trial investigates the safety and efficacy of adjuvant erlotinib in EGFR mutation-positive NSCLC. Methods: Patients (pts) with surgically resected stage IA-IIIA NSCLC harboring activating EGFR mutations were treated with 150 mg/day of erlotinib for 2 years (y) after completion of any standard adjuvant chemotherapy and/or radiotherapy. The trial was designed to enroll 36 patients, and powered to demonstrate a primary endpoint of 2 y disease free survival (DFS) exceeding 85%, which would suggest improvement over the historically expected 70% 2 y DFS in early stage EGFR-mutant NSCLC (J Thorac Oncol 6:569). Results: Thirty-six pts were enrolled at five sites between 1/08 and 11/09; 53% stage I; 19% stage II; 28% stage IIIA. Toxicities were typical of erlotinib; no grade 4 or 5 events or pneumonitis occurred. 8 pts (22%) required one dose reduction to 100 mg/day and 5 (14%) two reductions to 50 mg/day for grade 3 or persistent grade 2 toxicities. 11 pts discontinued before 2 full years (<1 month (mo) [4], 1-12 mo [2] and 12-23 mo [5]) for toxicities [6], patient preference [3], prostate cancer [1] and recurrence [1]. After a median follow-up of 2.5 y, the 2 y DFS from enrollment is 94% (95% CI 80%, 99%). 10 patients have recurred, 1 during erlotinib treatment and the others after stopping erlotinib (interval before recurrence 2 mo [1], 6-12 mo [4], >12 mo [4]). Genotyping on repeat biopsies from seven of the recurrent cases is underway, as is assessment of response to subsequent erlotinib therapy. Two pts have died of recurrence: one at 1.5 y who stopped erlotinib after 1 mo for toxicity, and one at 2 y who progressed while on erlotinib. Conclusions: This is the first prospective study to report the efficacy of adjuvant erlotinib in NSCLC pts with EGFR mutations. This approach is feasible and yields excellent 2y DFS compared to historical genotype-matched controls. This trial was subsequently expanded to 100 pts to permit subgroup analysis by stage.

Purpose NCCTG (North Central Cancer Treatment Group) N9831 is the only randomized phase III trial evaluating trastuzumab added sequentially or used concurrently with chemotherapy in resected stages I to III invasive human epidermal growth factor receptor 2–positive breast cancer. Patients and Methods Patients received doxorubicin and cyclophosphamide every 3 weeks for four cycles, followed by paclitaxel weekly for 12 weeks (arm A), paclitaxel plus sequential trastuzumab weekly for 52 weeks (arm B), or paclitaxel plus concurrent trastuzumab for 12 weeks followed by trastuzumab for 40 weeks (arm C). The primary end point was disease-free survival (DFS). Results Comparison of arm A (n = 1,087) and arm B (n = 1,097), with 6-year median follow-up and 390 events, revealed 5-year DFS rates of 71.8% and 80.1%, respectively. DFS was significantly increased with trastuzumab added sequentially to paclitaxel (log-rank P < .001; arm B/arm A hazard ratio [HR], 0.69; 95% CI, 0.57 to 0.85). Comparison of arm B (n = 954) and arm C (n = 949), with 6-year median follow-up and 313 events, revealed 5-year DFS rates of 80.1% and 84.4%, respectively. There was an increase in DFS with concurrent trastuzumab and paclitaxel relative to sequential administration (arm C/arm B HR, 0.77; 99.9% CI, 0.53 to 1.11), but the P value (.02) did not cross the prespecified O'Brien-Fleming boundary (.00116) for the interim analysis. Conclusion DFS was significantly improved with 52 weeks of trastuzumab added to adjuvant chemotherapy. On the basis of a positive risk-benefit ratio, we recommend that trastuzumab be incorporated into a concurrent regimen with taxane chemotherapy as an important standard-of-care treatment alternative to a sequential regimen.

4537 Background: Although the adjuvant chemoradiation therapy has gained popularity and has become the standard of care in patients with resected gastric cancer in U.S., the role of chemoradiation therapy after extended D2 dissection has been questioned. We conducted a phase III trial to compare capecitabine/cisplatin (XP) vs XP + radiotherapy (RT) in curatively D2 resected gastric cancer patients in terms of disease free survival and overall survival. Methods: Eligibility criteria were as follows: stage Ib (T1N1, T2bN0) - IV (M1 excluded), curatively ≥ D2 resected gastric adenocarcinoma. XP only: X 2,000 mg/m2/d D1∼14, CDDP 60 mg/m2 D1 repeated every 3 weeks, 6 cycles; XP + RT: X 2,000 mg/m2/d D1∼14, CDDP 60 mg/m2 D1 x 2 cycles ⋄ RT 45 Gy (25 fractions) + X 1,650 mg/m2/d during RT ⋄ X 2,000 mg/m2/d D1∼14, CDDP 60 mg/m2 D1 x 2 cycles. The primary endpoint is 3-year disease-free survival. Results: From October 2004 to April 2008, 458 patients (XP arm: 228 patients; XP/RT arm: 230 patients) were enrolled. In XP arm, 172 (75%) of 228 enrolled patients completed 6 cycles of chemotherapy. In XP + RT arm, 188 (82%) of 230 patients completed the full course of XP 2 cycles - X + RT - XP 2 cycles. Conclusions: Safety and feasibility analysis of the two arms will be reported at the meeting. No significant financial relationships to disclose.

363 Background: Irinotecan (CPT-11) has demonstrated antitumor activity against metastatic colorectal cancer used alone or with 5-fluorouracil (5FU)/leucovorin (LV). Two arms with CPT-11, 5FU, and LV (FOLFIRI) +/- cetuximab (Cmab) were originally included in N0147. However, after CALGB 89803 (J Clin Oncol. 25:3456, 2007), PETACC-3 (J Clin Oncol. 27:3117, 2009), and Accord02 (Ann Oncol. 20:674, 2009) showed no benefit to the three-drug combination in adjuvant therapy, the CPT-11 arms of N0147 were discontinued. We report the outcomes for patients given FOLFIRI +/- Cmab. Methods: Following a signed informed consent patients with resected stage III colon cancer were randomized to one of 6 arms including 12 biweekly cycles of CPT-11 180 mg/m2 d1 with LV 400 mg/m2, 5FU 400 mg/m2 bolus IV, then 46-hr IV 5FU 2,400 mg/m2 on d1-2 without (Arm B, FOLFIRI) or with Cmab (Arm E) 400 mg/m2 d1 cycle 1 then Cmab at 250 mg/m2 d1 and 8. Primary endpoint was 3-year disease-free survival (DFS). Secondary endpoints included overall survival (OS) and toxicity. Results: 156 patients (Arm B-111, Arm E-45) were enrolled; median follow-up on 81 patients in Arm B was 60.3 months and 58.2 months in Arm E for 41 patients. wtKRAS (vs mt) status was associated with improved DFS (HR=0.6 [95% CI 0.4-1.1], p = 0.09) and OS (HR 0.7 [95% CI 0.4-1.5], p = 0.38). The addition of Cmab improved DFS and OS in the overall group and within wtKRAS pts. Grade greater than III non-hematologic adverse effects were significantly increased in the Cmab arm (46% vs. 64%, p = 0.05). Conclusions: In this randomized phase III trial adjuvant FOLFIRI resulted in a 3-year DFS lower than that expected for FOLFOX. Trends for improved DFS and OS with the addition of Cmab were observed in patients with resected stage III colon cancer patients, regardless of KRAS status.

e18013 Background: Adjuvant chemotherapy demonstrated a 5-15% benefit in 5-year survival in early-stage NSCLC. Endostar,a recombinant human Endostatin, could inhibit tumor angiogenesis. In a phase III trial, the addition of Endostar to NP regimen resulted in higher response rate, clinical benefit rate and longer median time to progression compared with NP alone in advanced NSCLC patients. Methods: Completely resected patients (stage IB-IIIA) were randomized to receive adjuvant NP plus Endostar (arm A, Vinorelbine 25mg/m2 on d1 and d8 plus Cisplatin 80 mg/m2 intravenously plus Endostar 7.5mg/m2 per day, iv, for 14 consecutive days. 21 days as one cycle(arm A) or NP regimen alone (arm B) for four cycles. The randomization was stratified by gender, stage and histology. The primary endpoint was OS and the secondary endpoints were RFS and safety. Results: 1037 patients (arm A: 520; arm B: 517) from 43 centers in China were enrolled between 9/2007 and 12/2010. Two arms were well-balanced with regard to age, gender, histology, stage, and resection type. 184 patients in arm A and 202 patients in arm B had relapsed disease or died. The median RFS was 34.1 months in arm A and 30.3 months in arm B (p=0.1573). 79.0% of patients in arm A and 76.0% of patients in arm B received 4 cycles of chemotherapy. Median survival time was not available at this time. Grade 3/4 toxicities in arm A included leukopenia (57.4%), neutropenia (75.0%), anemia (12.9%), nausea (11.3%). Grade 3/4 toxicities in arm B included leukopenia (35.0%) neutropenia (60.5%), anemia (8.5%) and nausea (8.5%). It is worth noting that the incidence of cardiac toxicities in arm A (26.3%) was slightly higher than that in arm B (21.4%). Conclusions: The preliminary result showed that patients in arm A experienced a longer median relapse-free survival time than in arm B (34.1 months vs. 30.3 months), although the difference was not statistically significant by far. The toxicity profiles for both arms were tolerable in this study. The patient follow-up is still ongoing.

Purpose Gemcitabine is standard of care in the adjuvant treatment of resectable pancreatic ductal adenocarcinoma (PDAC). The epidermal growth factor receptor tyrosine kinase inhibitor erlotinib in combination with gemcitabine has shown efficacy in the treatment of advanced PDAC and was considered to improve survival in patients with primarily resectable PDAC after R0 resection. Patients and Methods In an open-label, multicenter trial, patients were randomly assigned to one of two study arms: gemcitabine 1,000 mg/m2 days 1, 8, 15, every 4 weeks plus erlotinib 100 mg once per day (GemErlo) or gemcitabine (Gem) alone for six cycles. The primary end point of the study was to improve disease-free survival (DFS) from 14 to 18 months by adding erlotinib to gemcitabine. Results In all, 436 patients were randomly assigned at 57 study centers between April 2008 and July 2013. A total of 361 instances (83%) of disease recurrence were observed after a median follow-up of 54 months. Median treatment duration was 22 weeks in both arms. There was no difference in median DFS (GemErlo 11.4 months; Gem 11.4 months) or median overall survival (GemErlo 24.5 months; Gem 26.5 months). There was a trend toward long-term survival in favor of GemErlo (estimated survival after 1, 2, and 5 years for GemErlo was 77%, 53%, and 25% v 79%, 54%, and 20% for Gem, respectively). The occurrence or the grade of rash was not associated with a better survival in the GemErlo arm. Conclusion To the best of our knowledge, CONKO-005 is the first study to investigate the combination of chemotherapy and a targeted therapy in the adjuvant treatment of PDAC. GemErlo for 24 weeks did not improve DFS or overall survival over Gem.

Adjuvant fluoropyrimidine-based chemotherapy has been the standard of care for resected stage III colon cancer since the 1990s; the evolution from 12 to 6 months of fluoropyrimidine therapy and the addition of oxaliplatin to fluoropyrimidine therapy have led to the current accepted standard. However, controversies remain. What is the benefit of adjuvant chemotherapy in stage II disease, and in whom? What is the optimal duration of adjuvant chemotherapy? How should patients with early-stage colon cancer be followed after surgery and adjuvant treatment? Recent evidence has emerged to help inform these important questions, including the International Duration Evaluation of Adjuvant therapy (IDEA) collaboration, which is the largest, prospective study in colon cancer with 12,834 patients. This review discusses current and future risk stratification strategies in stage II disease: the optimal duration of adjuvant oxaliplatin-containing chemotherapy in stage II and III disease according to the IDEA study, and the recent evidence and updated recommendations for surveillance of early-stage colon cancer after resection.

PURPOSE MINDACT demonstrated that 46% of patients with early breast cancer at high clinical but low genomic risk on the basis of MammaPrint may safely avoid adjuvant chemotherapy. A second random assignment (R-C) compared docetaxel-capecitabine with an anthracycline-based regimen. PATIENTS AND METHODS R-C randomly assigned patients 1:1 between standard anthracycline-based regimens, with or without taxanes (control) and experimental docetaxel 75 mg/m2 intravenously plus oral capecitabine 825 mg/m2 two times per day for 14 days (DC) every 3 weeks for 6 cycles. The primary end point was disease-free survival (DFS). Secondary end points included overall survival and safety. RESULTS Of 2,832 patients, 1,301 (45%) were randomly assigned, and 97% complied with R-C assignment. In the control arm, 29.6% only received taxanes (0.5% of N0 patients). DFS events (n = 148) were much less than required (n = 422) as a result of a lower-than-expected accrual and event rate. At 5 years of median follow-up, DFS was not different between DC (n = 652) and control (n = 649; 90.7% [95% CI, 88% to 92.8%] v 88.8% [95% CI, 85.9% to 91.1%]; hazard ratio [HR], 0.83 [95% CI, 0.60 to 1.15]; P = .26). Overall survival (HR, 0.91 [95% CI, 0.54 to 1.53]) and DFS in the clinical high and genomic high-risk subgroup (86.1% v 88.1%; HR, 0.83 [95% CI, 0.58 to 1.21]) were similar in both arms. DC led to more grade 1 neuropathy (27.1% v 11.2%) and more grade 2 hand/foot syndrome (28.5% v 3.3%) and diarrhea (13.7% v 5.8%). Serious cardiac events occurred in 9 patients (control, n = 4; DC, n = 5). Fifty-three patients developed second cancers (control, n = 32; DC, n = 21; leukemia: 2 v 1). Five treatment-related deaths occurred (control, 2 [0.3%]; DC, 3 [0.5%]). CONCLUSION Although underpowered, this second randomization in MINDACT did not show any improvement in outcome or safety with the use of DC compared with anthracycline-based chemotherapy.
