Background. The prognostic values of weight loss and body mass index (BMI) in esophageal carcinoma remain controversial. This study aimed to evaluate the impacts of weight loss on the survival of patients undergoing radical surgery and adjuvant chemotherapy. Methods. The medical records of 189 consecutive patients with nonmetastatic esophageal carcinoma treated in our hospital between January 2012 and December 2013 were reviewed, and 121 patients were included for analysis. Results. Kaplan-Meier analysis revealed that the 3-year overall survival rate was significantly higher in the low pretreatment weight loss (pre-LWL) group than in the high pretreatment weight loss (pre-HWL) group (P<0.001). In addition, the 3-year overall survival rate of normal weight group was higher than that of overweight and underweight groups (P=0.007). Multivariate Cox proportional hazards analysis showed that pre-LWL group had a significantly better 3-year overall survival than pre-HWL group (P=0.027, HR = 1.89, and 95% CI = 1.07–3.32). pN stage and age were also the survival prognostic factors. Conclusions. Our study showed that low pretreatment weight loss predicted a better survival outcome in the esophageal carcinoma patients with radical surgery and adjuvant chemotherapy. However, BMI and weight loss during treatment had no impact on the survival outcome.

360 Background: The effect of adjuvant chemotherapy on survival after resection for gallbladder adenocarcinoma (GBC) is based on limited evidence. Since prospective trials are not generally practical for GBC, we sought to evaluate current best evidence to evaluate the role of adjuvant chemotherapy in multiple clinical scenarios by analyzing data from the U.S. National Cancer Database (NCDB). Methods: Patients who underwent resection for GBC diagnosed between 2004 and 2012 were identified in the NCDB. The effect of adjuvant therapy on overall survival (OS) was assessed using Kaplan-Meier analysis and Cox proportional hazards regression modeling. Results: 10,402 patients met inclusion criteria. Median follow-up was 14 months. Median survival was 16 months. One- and five-year OS were 57% and 23%, respectively. 3,509 patients (34%) received any modality of adjuvant therapy. Receipt of adjuvant therapy improved one-year OS (63% vs 55%, p < 0.01), but median OS was minimally changed (17 vs 15 months, NS). Adjuvant therapy was associated with improved one-year OS in T3 and T4N1 disease (Table 1). Only chemoradiation therapy was associated with improved one-year OS for T2 disease. Adjuvant chemotherapy was associated with worse one-year OS in T1N0 disease. Conclusions: Using data from the US NCDB, adjuvant therapy for resected gallbladder adenocarcinoma is associated with improved one-year overall survival with the exception of T1N0 disease. In the absence of prospective studies in this rare disease, retrospective data can provide insights into successful treatment strategies and guidelines for GBC. [Table: see text]

669 Background: Although adjuvant chemotherapy with S-1 has improved overall survival and progression-free survival (PFS) in patients with resected pancreatic cancer, the duration evaluation of adjuvant chemotherapy with S-1 have not established yet. Methods: We did a randomized, multicenter, phase 2 trial undertaken at 15 hospitals in Japan. Patients who were Eastern Cooperative Oncology Group performance states of 0 or 1 and aged 20 years or older were eligible. Patients with resected pancreatic cancer were randomly assigned (in a 1:1 ratio) to receive S-1 [40 mg, 50 mg, or 60 mg according to body-surface area, orally administered twice a day for 28 days followed by a 14 day rest, every 6 weeks [one cycle], for up to four cycles (6 months)] or up to eight cycles (12 months). The primary end point was overall survival rate. Secondary endpoints included PFS and safety. Results: The population consisted of 82 patients in the S-1 for 6 months group and 82 patients in the S-1 for 12 months group. The 2-year overall survival rate was 71.4% in the S-1 for 6 months group and 65.4% in the S-1 for 12 months, and the median overall survival was 31.0 months in the S-1 for 6 months group and 26.3 months in the S-1 for 12 months group [hazard ratio (HR) 1.23, 95% confidence interval (CI) 0.76-1.99, p = 0.377]. The PFS at 2 years was 56.8% in the S-1 for 6 months group, and 51.2% in the S-1 for 12 months. The HR for recurrence of S-1 for 6 months, compared with S-1 for 12 months, was 1.23 (95%CI 0.76-1.99, p = 0.392). Twenty-nine (35.3%) patients in the S-1 for 6 months group and 46 (56.0%) in the S-1 for 12 months group discontinued treatment before completion. In regard to patients completed treatment, the S-1 for 12 months group showed tendency to favorable prognosis on PFS compared with the S-1 for 6 months group (log-rank test; p = 0.175). Conclusions: In patients with resected pancreatic cancer, adjuvant chemotherapy with S-1 for 12 months is not superior to that for 6 months in terms of median overall survival and PFS. For patients who can tolerate adjuvant chemotherapy with S-1 for 6 months well, continuing treatment for up to 12 months may improve the prognosis.

e18038 Background: Timeliness of adjuvant chemotherapy is an important predictor of survival for patients with breast and colorectal cancer whereby long delays has been shown to detrimentally impact outcomes. The effects of adjuvant treatment timing remain largely unknown for early pancreatic cancer. This study aims to identify independent predictors of treatment timeliness and overall survival in this patient population. Methods: We conducted a retrospective, population-based analysis of 179 patients with resected pancreatic cancer who subsequently started adjuvant chemotherapy between 2008 and 2014 at any 1 of 6 cancer centers across British Columbia, Canada. Logistic regression was used to identify predictive factors for adjuvant chemotherapy timing. Prognostic factors for survival were ascertained using multivariate Cox proportional hazards models. Results: Our study cohort included 91 men (51%) and 88 women (49%). At time of diagnosis, 145 patients (81%) had nodal involvement and 107 patients (60%) had good ECOG performance status (ECOG 0-1). The median age of diagnosis was 67 (range 37-85) years. The median interval between surgery and start of adjuvant chemotherapy was 70 (range 19-46) days. Abnormal bilirubin was the only factor significantly correlated with delayed chemotherapy (OR, 3.89; 95% CI, 1.55-9.73; P = 0.004). Median overall survival was 468 days following resection (95% CI, 425-538). Multivariate survival analysis showed that high CA 19-9 levels (HR, 2.44, 95% CI: 1.36-4.40, P = 0.003) and abnormal bilirubin (HR, 0.40; 95% CI, 0.22-0.73; P = 0.003) were prognostic factors for overall survival. Median survival for patients who waited up to 35, 70 or 105 days for chemotherapy following resection were 588 days (95% CI, 270-776), 490 days (95% CI, 360-688) and 466 days (95% CI, 432-538) respectively. Overall, timeliness was not predictive of survival (HR, 1.12; 95% CI, 0.64-1.97; P= 0.70). Conclusions: Patients with hyperbilirubinema experienced delays in adjuvant chemotherapy, likely due to the need for relief of biliary obstruction and subsequent recovery. However, timeliness of adjuvant chemotherapy did not influence outcomes, suggesting that treatment should still be considered irrespective of timing.

Abstract Background Lymphovascular invasion (LVI), which includes vascular or lymphatic invasions, is a representative prognostic factor even in patients with resected stage IA non-small cell lung cancer (NSCLC). Because tegafur-uracil is effective on cancers with LVI, we conducted a multi-center single-arm phase II study to estimate the efficacy of adjuvant tegafur-uracil in patients with LVI-positive stage IA NSCLC. Methods Patients with completely resected LVI-positive stage IA NSCLC were registered. LVI was diagnosed by consensus of two of three pathologists. Adjuvant chemotherapy consisted of 2 years of oral tegafur-uracil at 250 mg/m2/day. Fifty-five patients from 7 institutions were enrolled from June 2007 to September 2012. Results Among the 52 eligible patients, 36 (69.2%) completed the treatment course. There were 39 male and 13 female patients. The observation period was calculated as 562 to 3107 days using the reverse Kaplan-Meier method. The 5-year overall and relapse free survival rates were 94.2 and 88.5% respectively, which were significantly better than that of any other studies conducted on patients with LVI-positive stage IA NSCLC. Notably, the overall survival rate was 15% better than that of our prior retrospective study. The retrospective analysis of stage IA NSCLC patients who had received an operation in the same period revealed that the 5-year overall survival rate of the LVI positive group was 73.6% when adjuvant chemotherapy was not applied. Among 55 safety analysis sets, 4 cases of grade 3 hepatic function disorder (9.1%) and 5 cases of grade 2 anorexia (10.9%) were most frequently observed. No grade 4 adverse effects were encountered. Conclusion A 2-year course of oral tegafur-uracil administration is feasible and might have a significant benefit in the adjuvant treatment of LVI-positive stage IA NSCLC.

Purpose Adjuvant chemotherapy is typically considered for patients with stage II colon cancer characterized by poor prognostic features, including obstruction, perforation, emergent admission, T4 stage, resection of fewer than 12 lymph nodes, and poor histology. Despite frequent use, the survival advantage conferred on patients with stage II disease by chemotherapy is yet unproven. We sought to determine the overall survival benefit of chemotherapy among patients with stage II colon cancer having poor prognostic features. Patients and Methods A total of 43,032 Medicare beneficiaries who underwent colectomy for stage II and III primary colon adenocarcinoma diagnosed from 1992 to 2005 were identified from the Surveillance, Epidemiology, and End Results (SEER) –Medicare database. χ2 and two-way analysis of variance were used to assess differences in patient- and disease-related characteristics. Five-year overall survival was examined using Kaplan-Meier survival analysis and Cox proportional hazards regression with propensity score weighting. Results Of the 24,847 patients with stage II cancer, 75% had one or more poor prognostic features. Adjuvant chemotherapy was received by 20% of patients with stage II disease and 57% of patients with stage III disease. After adjustment, 5-year survival benefit from chemotherapy was observed only for patients with stage III disease (hazard ratio[HR], 0.64; 95% CI, 0.60 to 0.67). No survival benefit was observed for patients with stage II cancer with no poor prognostic features (HR, 1.02; 95% CI, 0.84 to 1.25) or stage II cancer with any poor prognostic features (HR, 1.03; 95% CI, 0.94 to 1.13). Conclusion Among Medicare patients identified with stage II colon cancer, either with or without poor prognostic features, adjuvant chemotherapy did not substantially improve overall survival. This lack of benefit must be considered in treatment decisions for similar older adults with colon cancer.

154 Background: Two double regimens, CAPEOX (CLASSIC trial) and docetaxel/S-1 (JACCRO GC-07), were standard treatment for curatively resected gastric cancer (GC) in Asia. However, the outcome of double regimens as postoperative adjuvant treatment remains unsatisfactory and the efficacy between oxaliplatin-based or taxane-based doublets is unknown. This study aimed to investigate if triplet improve survival compared with doublets and difference between oxaliplatin-based or taxane-based doublets. Methods: We found the patients with gastric cancer who received FOLFOX or POF or TF as adjuvant chemotherapy after curatively resection between 2002 and 2015 from our hospital. The POF consisted of a three-hour infusion of paclitaxel 135 mg/m2, followed by FOLFOX omitted 5-Fu bolus. The TF is a substitution of paclitaxel 135 mg/m2 for oxaliplatin of FOLFOX. We checked the overall survival rate and the frequency of adverse reaction among the three groups. Results: We retrospectively studied 275 patients (POF 26, FOLFOX 172, TF 67). One, two, and three years OS rate were shown in table. POF was the worst survival among three regimens (p = 0.04). The patients with POF were shown more grade ¾ toxicity than two doublets. The patients with TF was more grade ¾ neutropenia, FOLFOX was more grade ¾ neuropathy. Conclusions: FOLFOX and TF which were similar in term of survival were recommended as adjuvant chemotherapy after curatively resection in the patients with gastric cancer. POF was less likely to improved survival than two doublets, which was not recommended. [Table: see text]

Abstract Purpose Colorectal cancer revealed over the last decades a remarkable shift with an increasing proportion of a right- compared to a left-sided tumor location. In the current study, we aimed to disclose clinicopathological differences between right- and left-sided colon cancer (rCC and lCC) with respect to mortality and outcome predictors. Methods In total, 417 patients with colon cancer stage I–IV were analyzed in the present retrospective single-center study. Survival rates were assessed using the Kaplan–Meier method and uni/multivariate analyses were performed with a Cox proportional hazards regression model. Results Our study showed no significant difference of the overall survival between rCC and lCC stage I–IV (p = 0.354). Multivariate analysis revealed in the rCC cohort the worst outcome for ASA (American Society of Anesthesiologists) score IV patients (hazard ratio [HR]: 16.0; CI 95%: 2.1–123.5), CEA (carcinoembryonic antigen) blood level > 100 µg/l (HR: 3.3; CI 95%: 1.2–9.0), increased lymph node ratio of 0.6–1.0 (HR: 5.3; CI 95%: 1.7–16.1), and grade 4 tumors (G4) (HR: 120.6; CI 95%: 6.7–2179.6) whereas in the lCC population, ASA score IV (HR: 8.9; CI 95%: 0.9–91.9), CEA blood level 20.1–100 µg/l (HR: 5.4; CI 95%: 2.4–12.4), conversion to laparotomy (HR: 14.1; CI 95%: 4.0–49.0), and severe surgical complications (Clavien-Dindo III–IV) (HR: 2.9; CI 95%: 1.5–5.5) were identified as predictors of a diminished overall survival. Conclusion Laterality disclosed no significant effect on the overall prognosis of colon cancer patients. However, group differences and distinct survival predictors could be identified in rCC and lCC patients.

The clinical results after carbon ion radiotherapy for the metastatic lung tumors believed to be in the state of oligo-recurrence were evaluated. One hundred and sixteen lesions in 91 patients with lung cancer metastasis were treated with carbon ion radiotherapy at our institute from April 1997 to February 2011. Regarding the prescribed dose, total dose ranged between 40 gray equivalents (GyE) and 80 GyE, and fraction size ranged from 1 to 16 fractions. After a median followup period of 2.3 years (range, 0.3–13.1 years), the statistical overall survival rate and local control rate were 71.2% and 91.9% at 2 years after treatment, respectively. Treatment-related side effects were not a clinical problem. When classified by the primary organ, there were 49 cases of lung cancer, 20 cases of colorectal cancer, and 22 cases of others. The overall survival rate and local control rate for lung metastasis cases from lung cancer at 2 years after treatment were 81.5% and 92.4%, respectively, and 65.0% and 92.0% regarding lung metastasis from colorectal cancer. Carbon ion beam therapy for the metastatic lung tumors is a safe therapy, and the therapeutic effect is comparable to the outcome obtained from reported surgical resections.

Aims The primary aim of this study was to determine the effect of the duration of symptoms (DOS) prior to diagnosis on the overall survival in patients with a primary bone sarcoma. Patients and Methods In a retrospective analysis of a sarcoma database at a single institution between 1990 and 2014, we identified 1446 patients with non-metastatic and 346 with metastatic bone sarcoma. Low-grade types of tumour were excluded. Our data included the demographics of the patients, the characteristics of the tumour, and the survival outcome of patients. Cox proportional hazards analysis and Kaplan–Meier survival analysis were performed, and the survivorship of the non-metastatic and metastatic cohorts were compared. Results In the non-metastatic cohort, a longer DOS was associated with a slightly more favourable survival (hazard ratio (HR) 0.996, 95% confidence interval (CI) 0.994 to 0.998, p < 0.001). In all types of tumour, there was no difference in survival between patients with a DOS of greater than four months and those with a DOS of less than four months (p = 0.566). There was no correlation between the year of diagnosis and survival (p = 0.741). A diagnosis of chondrosarcoma (HR 0.636, 95% CI 0.474 to 0.854, p = 0.003) had the strongest positive effect on survival, while location in the axial skeleton (HR 1.76, 95% CI 1.36 to 2.29, p < 0.001) had the strongest negative effect on survival. Larger size of tumour (HR 1.05, 95% CI 1.03 to 1.06, p < 0.001) and increased age of the patient (HR 1.02, 95% CI 1.01 to 1.03, p < 0.001) had a slightly negative effect on survival. Metastatic and non-metastatic cohorts had similar median DOS (16 weeks, p = 0.277), although the median survival (15.5 months vs 41 months) and rates of survival at one year (69% vs 89%) and five years (20% vs 59%) were significantly shorter in the metastatic cohort. Conclusion A longer DOS prior to diagnosis is not associated with a poorer overall survival in patients with a primary bone sarcoma. Location in the axial skeleton remains the strongest predictor of a worse prognosis. This may be helpful in counselling patients referred for evaluation on a delayed basis.

Colorectal cancer (CRC) arises from chromosomal instability, resulting from aberrant hypermethylation in tumor suppressor genes. This study identified hypermethylated genes in CRC and investigated how they affect clinical outcomes. Methylation levels of specific genes were analyzed from The Cancer Genome Atlas dataset and 20 breast cancer, 16 esophageal cancer, 33 lung cancer, 15 uterine cancer, 504 CRC, and 9 colon polyp tissues and 102 CRC plasma samples from a Taiwanese cohort. In the Asian cohort, Eps15 homology domain-containing protein 3 (EHD3) had twofold higher methylation in 44.4% of patients with colonic polyps, 37.3% of plasma from CRC patients, and 72.6% of CRC tissues, which was connected to vascular invasion and high microsatellite instability. Furthermore, EHD3 hypermethylation was detected in other gastrointestinal cancers. In the Asian CRC cohort, low EHD3 mRNA expression was found in 45.1% of patients and was connected to lymph node metastasis. Multivariate Cox proportional-hazards survival analysis revealed that hypermethylation in women and low mRNA expression were associated with overall survival. In the Western CRC cohort, EHD3 hypermethylation was also connected to overall survival and lower chemotherapy and antimetabolite response rates. In conclusion, EHD3 hypermethylation contributes to the development of CRC in both Asian and Western populations.
