    Abstract: We evaluated the role of oxaliplatin as adjuvant chemotherapy in patients with rectal cancer who received preoperative chemoradiotherapy (CRT) with fluoropyrimidine monotherapy and total mesorectal excision (TME). METHODS The ADORE trial (adjuvant oxaliplatin in rectal cancer) is a multicenter, randomized trial in patients with postoperative ypStage II (ypT3-4N0) or III (ypT any N1-2) rectal cancer after fluoropyrimidine-based preoperative CRT and TME. Patients were randomly assigned (1:1) to receive adjuvant chemotherapy either with FL (fluorouracil 380 mg/m 2 and leucovorin 20 mg/m 2 ) or FOLFOX (oxaliplatin 85 mg/m 2 , leucovorin 200 mg/m 2 , and fluorouracil bolus 400 mg/m 2 on day 1, fluorouracil infusion 2,400 mg/m 2 for 46 hours). Stratification factors included ypStage and participating center. Primary end point was disease-free survival (DFS). RESULTS A total of 321 patients were enrolled between November 19, 2008, and June 12, 2012. Six-year DFS rates were 68.2% in the FOLFOX arm versus 56.8% in the FL arm, with a stratified hazard ratio of 0.63 (95% CI, 0.43 to 0.93; P = .018) by intention-to-treat analysis. In the subgroup analysis for DFS, FOLFOX was favorable versus FL in patients with ypStage III, ypN1b, ypN2, high-grade histology, minimally regressed tumor, and an absence of lymphovascular or perineural invasion. Six-year overall survival rate was 78.1% in the FOLFOX arm versus76.4% in the FL arm (hazard ratio, 0.73; 95% CI, 0.45 to 1.19; P = .21). In the subgroup analysis for OS, FOLFOX was favorable versus FL in patients with ypN2 and minimally regressed tumor. CONCLUSION Adjuvant FOLFOX improved DFS in patients with rectal cancer with ypStage II and III disease after preoperative CRT. Adjuvant FOLFOX may be considered on the basis of the postoperative pathologic stage in those who received preoperative CRT and TME.

    Abstract: 3076 Background: HM781-36B is a pan-HER tyrosine kinase inhibitor, which showed a potent activity against the gefitinib- or erlotinib-resistant, EGFR L858R/T790M double mutant cells. A phase I study was conducted to determine the MTD, pharmacokinetics, and antitumor activity. Methods: Eligible pts had advanced malignancies refractory to standard therapies. Standard 3+3 scheme was used in the dose escalation part, and additional 12 pts were enrolled in the expansion cohort of molecular enrichment. Results: In dose-escalation part, 43 pts (median age: 55 yrs (range 25-82), M:F=25:18, ECOG PS 0/1/2/3: 23/17/2/1, median prior chemotherapy: 4) were treated. DLTs were G3 diarrheas in 5 pts, one at 12 mg, 16 mg, 24 mg, and two at 32 mg. The MTD was determined as 24mg. The most common drug-related adverse events were diarrhea, stomatitis, rash, pruritus, and anorexia. Among 41 evaluable pts, 4 pts achieved PR (1 unconfirmed, duration of response: 11.9 mo, 7.07 mo+, 4.5 mo+), and 19 pts had SD. Two of 4 PR pts were Her2-positive breast cancer pts. The median duration of treatment in pts with PR or SD was 3.87 (2.47- 15.17) months. In the dose range of 0.5 to 24 mg, it showed linear pharmacokinetics proportional to dose-escalation, relatively short half-life, and little accumulation. Additional 12 pts in the expansion cohort are under treatment at 24 mg (6 pts: EGFR-mutant NSCLC, 3 pts: Her2-positive gastric cancer, 2 pts: Her2-positive breast cancer, 1 pt: rectal cancer). Conclusions: HM781-36B was safe and well tolerable in advanced solid tumors. Preliminary evidence of anticancer activity has been observed. Updated data will be presented at the meeting.

    Abstract: e14580 Background: TS-1 has shown good efficacy against unresectable advanced gastric cancer (AGC). Conventionally TS-1 containing chemotherapy (CTx) is performed on 5-weekly or 6-weekly basis. We lack robust evidence for the efficacy and safety of 3-weekly TS-1 containing CTx. In Korea, 3-weekly TS-1 containing CTx can be used as off-label under permission of Health Insurance Review and Assessment service (HIRA). We and HIRA conducted this study to confirm the efficacy and tolerability of 3-weekly TS-1 containing CTx in unresectable AGC. Methods: We retrospectively analyzed patients with unresectable AGC who received 3-weekly TS-1 containing CTx between June 2007 and January 2011. In 3-weekly TS-1 monotherapy, TS-1 40-60mg depending on patient’s body surface area was administered orally twice a day for 14 days followed by a 1-week rest every 3 weeks. In 3-weekly TS-1/cisplatin combination CTx, TS-1 40mg/m 2 was given orally twice a day for 14 days followed by 1-week rest and cisplatin 60 mg/m 2 on day 1 was given by intravenous infusion every 3 weeks. Results: A total of 1372 patients (TS-1 monotherapy: 265 (19.3%), TS-1/cisplatin : 1107 (80.7%)) were enrolled from 31 institutions. Response rate of 3-weekly TS-1 monotherapy was 18.1%. Progression-free survival (PFS) and overall survival (OS) were 5.2 months (95% C.I., 4.5-5.9) and 14.3 months (95% C.I., 10.6-17.9), respectively. Response rate of 3-weekly TS-1/cisplatin was 29.4%. PFS and OS of 3-weekly TS-1/cisplatin were 6.8 months (95% C.I., 6.3-7.4) and 16.1 months (95% C.I., 14.4-17.9) respectively. Common toxicities of TS-1 monotherapy included nausea/vomiting (N/V) (13.6%), anemia (13.2%) and neutropenia (10.2%). However, the incidences of more grade 3/4 toxicities were less than 3.0%. All grades of neutropenia, N/V and anemia occurred in 35.4%, 21.1% and 13.3% of patients receiving 3-weekly TS-1/cisplatin. However, grade 3/4 toxicities including neutropenia, N/V and anemia occurred in only 17.8%, 3.0% and 2.9%. Conclusions: Three-weekly TS-1 monotherapy or TS-1/cisplatin CTx showed good efficacy and well tolerability. Our study suggests that 3-weekly scheduled regimens may be a good treatment option for unresectable AGC patients.

    Abstract: 623 Background: Ethnic diversity of genetic polymorphism can result in individual differences in the efficacy and toxicity of cancer chemotherapy. Methods: A total of 292 Korean patients (183 men and 109 women) from six hospitals in Korea were prospectively enrolled. Patients had resected stage III or high-risk stage II colon cancer and were treated with 12 cycles of adjuvant oxaliplatin plus leucovorin plus 5-fluorouracil (FOLFOX) chemotherapy. 20 germline polymorphisms in 10 genes (TS, MTHFR, ERCC1, XPD, XRCC1, ABCC2, AGXT, GSTP1, GSTT1 and GSTM1) were analyzed from peripheral blood. TS genotype in 5’UTR was classified as ‘high’ (2R/3G, 3C/3G, and 3G/3G) or ‘low’ (2R/2R, 2R/3C, and 3C/3C). Results: Most patients (86.3%) received 12 complete cycles of FOLFOX chemotherapy. In contrast to previous studies in Caucasians, neutropenia (grade 3–4, 60.5%) was frequently observed in our Korean patients, whereas only 16.4% experienced grade 2 or more sensory neuropathy. Neutropenia was more frequent in MTHFR 677TT [adjusted odds ratio (OR) 2.32, 95% confidence interval (CI) 1.19–4.55] and ERCC1 19007TT (adjusted OR 4.58, 95% CI 1.20–17.40) genotypes. Patients harboring XRCC1 23885GG had lower risk of neuropathy (adjusted hazard ratio 0.56, 95% CI 0.32-0.99) and longer time to the onset of grade 2-4 neuropathy. MTHFR 677TT and XRCC1 23885GG genotype was also more prevalent in Koreans compared to Caucasians, and the difference of genotypic frequency could partly explain the ethnically different toxicity profile. After median 49.4 months of follow-up, there were 58 (19.9%) relapses and 19 (6.5%) deaths. TS ‘low’ genotype [adjusted hazard ratio (OR) 1.83, 95% CI 1.003–3.34] was significantly related to shorter disease-free survival. Overall survival was not significantly different according to the polymorphisms. Conclusions: Polymorphisms in MTHFR, XRCC1 and TS are related to toxicities and disease-free survival in patients with colon cancer. These polymorphisms may explain the ethnic difference in toxicity profile following adjuvant FOLFOX chemotherapy.

    Abstract: To determine whether an Internet-based tailored education program is effective for disease-free cancer survivors with cancer-related fatigue (CRF). Patients and Methods We randomly assigned patients who had completed primary cancer treatment within the past 24 months in any of four Korean hospitals and had reported moderate to severe fatigue for at least 1 week to participate in a 12-week, Internet-based, individually tailored CRF education program or to receive routine care. We based the program on the CRF guidelines of the National Comprehensive Cancer Network (NCCN) and incorporated the transtheoretic model (TTM). At baseline and 12 weeks, we used the Brief Fatigue Inventory (BFI) and Fatigue Severity Scale (FSS) as primary outcomes and the Hospital Anxiety and Depression Scale (HADS) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) for secondary outcomes. Results We recruited 273 participants and randomly assigned 136 to the intervention group. Compared with the control group, the intervention group had an improvement in fatigue as shown by a significantly greater decrease in BFI global score (−0.66 points; 95% CI −1.04 to −0.27) and FSS total score (−0.49; 95% CI, −0.78 to −0.21). In secondary outcomes, the intervention group experienced a significantly greater decrease in HADS anxiety score (−0.90; 95% CI, −1.51 to −0.29) as well as global quality of life (5.22; 95% CI, 0.93 to 9.50) and several functioning scores of the EORTC QLQ-C30. Conclusion An Internet-based education program based on NCCN guidelines and TTM may help patients manage CRF.

    Abstract: 4113 Background: Clinical heterogeneity in gastric cancer is likely due to biological differences among patients. Molecular subtypes and their associated biomarkers need to be established to improve treatment of this disease. We aimed to uncover subgroups of gastric cancer that have distinct biological characteristics associated with clinical outcome and to identify potential best treatments or therapeutic targets for each subgroup. Methods: We analyzed gene expression profiling data from gastric cancer cell lines and 267 patients with gastric cancer to uncover tumor subtypes and identify a gene expression signature associated with prognosis and response to adjuvant chemotherapy. The association of the signature with prognosis was validated in an independent cohort of 200 patients, and its association with response to adjuvant therapy was validated by cell culture experiments. Results: We identified an expression signature of 88 genes that specifically reflected activation of the oncogene YAP1. Compared with patients without this signature, patients with the YAP1 signature had significantly poorer prognosis. In multivariate analysis, the signature was the strongest indicator of overall survival among all demographic and clinical variables examined together (hazard ratio, 2.1; 95% confidence interval, 1.3-3.3;P = .002). Activation of YAP1 was significantly associated with resistance to adjuvant chemotherapy. We also demonstrated that the Notch pathway is a potential therapeutic target for overcoming chemoresistance mediated by YAP1. Conclusions: Activation of the oncogene YAP1 is significantly associated with poorer survival of patients with gastric cancer and induces chemoresistance to this disease. Therefore, YAP1 may be highly attractive therapeutic target for patients with gastric cancer resistant to standard chemotherapy.

    Abstract: To ascertain the attitude of cancer patients and their families toward disclosure of terminal illness to the patient. Patients and Methods We constructed a questionnaire that included demographic and clinical information and delivered it to 758 consecutive individuals (433 cancer patients and 325 families that have a relative with cancer) at seven university hospitals and one national cancer center in Korea. Results 380 cancer patients and one member from each of 281 families that have a relative with cancer completed the questionnaire. Cancer patients were more likely than family members to believe that patients should be informed of the terminal illness (96.1% v 76.9%; P 〈 .001). Fifty percent of the family members and 78.3% of the patients thought that the doctor in charge should be the one who informs the patient. Additionally, 71.7% of the patients and 43.6% of the family members thought that patients should be informed immediately after the diagnosis. Stepwise multiple logistic regression indicated that the patient group was more likely than the family group to want the patient to be informed of the terminal illness (odds ratio [OR], 9.76; 95% CI, 4.31 to 22.14), by the doctor (OR, 4.00; 95% CI, 2.61 to 6.11), and immediately after the diagnosis (OR, 3.64; 95% CI, 2.45 to 5.41). Conclusion Our findings indicated that most cancer patients want to be informed if their illness is terminal, and physicians should realize that the patient and the family unit may differ in their attitude toward such a disclosure. Our results also reflect the importance of how information is given to the patient.
