The ideal treatment modality for metastatic cancer would be a local treatment that can destroy primary tumors while inducing an effective systemic anti-tumor response. To this end, we developed laser immunotherapy, combining photothermal laser application with an immunoadjuvant for the treatment of metastatic cancer. Additionally, to enhance the selective photothermal effect, we integrated light-absorbing nanomaterials into this innovative treatment. Specifically, we developed an immunologically modified carbon nanotube combining single-walled carbon nanotubes (SWNTs) with the immunoadjuvant glycated chitosan (GC). To determine the effectiveness of laser irradiation, a series of experiments were performed using two different irradiation durations — 5 and 10 min. Rats were inoculated with DMBA-4 cancer cells, a metastatic cancer cell line. The treatment group of rats receiving laser irradiation for 10 min had a 50% long-term survival rate without residual primary or metastatic tumors. The treatment group of rats receiving laser irradiation for 5 min had no long-term survivors; all rats died with multiple metastases at several distant sites. Therefore, Laser+SWNT–GC treatment with 10 min of laser irradiation proved to be effective at reducing tumor size and inducing long-term anti-tumor immunity.

The possibilities and results of multimodal treatment in rectal cancer were reviewed with respect to the results of surgical treatment only. Based on the results of 4 studies, reducing local relapse rates and increasing long term survival rates significantly, postoperative radiochemotherapy (RCT) + chemotherapy (CT) should remain the recommended standard for R0 resected UICC II and III rectal cancers. The addition of RT to adjuvant CT reduces local relapses without significant impact on survival (NSABP R-02). Vice versa, the addition of CT to RT or an improved CT in the RCT-concept prolongs survival. Preoperative neoadjuvant radiotherapy (RT) reduced local relapse rates in 9 studies, and extended survival in one study that evaluated all eligible patients. Preoperative RT reduced local relapse rates in addition to total mesorectal excision (TME) but did not extend survival. The preoperative RCT + CT downstages resectable and nonresectable tumors and induces a higher sphincter preservation rate. Phase III data justifying its routine use in all UICC II + III stages are not yet available. This treatment may be routinely applied in nonresectable primary tumors or local relapses. Preoperative RCT (or RT) may evolve as standard, if the patient selection is improved and postoperative morbidity and long term toxicity reduced. Intraoperative RT could be added to this concept or be used together with preoperative/postoperative RT at the same indications. Postoperative adjuvant RT reduced local relapses significantly in a single trial, and no impact on survival time is reported. Since postoperative RT is inferior to preoperative RT, this treatment cannot be recommended, if RT is chosen as a single treatment modality in adjunction to surgery. The results of local tumor excisions may be improved with pre- or postoperative RCT + CT. In the future, multimodal treatment of rectal cancer might be more effective, if individualized according to prognostic factors.

Background and Aim: Colorectal cancer is a common cancer in the Nordic countries and 50% of the patients develop liver metastases. Liver resection may result in long term survival. Proper staging is therefore essential and CT is the standard imaging modality. We examined whether additional FDG-PET improves therapeutic management of patients with colorectal liver metastases. Patients and Methods: Fifty-four consecutive patients were enrolled. Each patient had a treatment plan made based on our standard evaluation. The patients then had a PET scan and the treatment plan was re-evaluated, taking these results into account. Results: In 76% of the cases, PET did not change the treatment plan due to complete concordance with CT. In another 19% of the cases, the plan was altered due to finding of more liver lesions by PET than by CT (four patients), fewer or no liver lesions (three patients), and extrahepatic lesions not visible on CT (three patients). In 5% of the cases, non-concordance between PET and CT did not change the therapeutic plan. Conclusion: Pre-treatment FDG-PET, used supplementary to CT, improved the treatment plan in one fifth of the patients with colorectal liver metastases.

PURPOSE In men with metastatic germ cell tumors (GCTs), risk-directed treatment is determined, in part, by a distinction between seminoma and nonseminomatous GCT (NSGCT). The importance of NSGCT cell type is uncertain. We evaluated the long-term impact of teratoma on survival in patients with NSGCT. METHODS Prechemotherapy, primary tumors from patients who received platinum-based chemotherapy were studied, and the histology was confirmed by a genitourinary pathologist. The cumulative incidence of disease-related death (CIDD) was the primary end point, and a competing-risk analysis was performed. RESULTS Tumors were available from 232 patients, including 193 with NSGCT. An element of teratoma was present in 82 NSGCT primary tumors (42%). With a median follow-up of 17 years (range, 0.3 to 35 years), 58 patients with NSGCT died, 47 as a result of GCT and 11 as a result of other causes. Most GCT deaths occurred within the first 5 years and were associated with pretreatment risk status ( P < .001). Death as a result of other causes rose steadily after 15 years and was not associated with risk status ( P = .66). A higher CIDD was observed in patients who had NSGCT with teratoma than those with NSGCT without teratoma and seminoma (5-year CIDD rate, 27.4%, 17.4%, and 10.3%, respectively; P = .03). A higher CIDD was observed in patients who had NSGCT with mature teratoma compared with those with either NSGCT with immature teratoma or NSGCT without teratoma (5-year CIDD rate, 38.1%, 19.9%, and 17.4%, respectively; P = .01). CONCLUSION The presence of teratoma, particularly mature teratoma, in an NSGCT primary tumor is associated with a higher CIDD, consistent with the hypothesis that differentiation is associated with adverse outcomes. Death as a result of non-GCT causes is not associated with risk status and must be separated from GCT death when evaluating long-term survival.

e15646 Background: The oophorectomy in isolated metastasis of ovary can lead to long term survival in patients with gastric cancer, but the clinical significance of oophorectomy in stage IV gastric cancer patients is not known well in this time. Methods: We reviewed the medical record of the 55 gastric cancer patients who were metastasis or recurrent in ovary at Dongsan Medical Center, Kimyung University School of Medicine, Daegu, Korea from 1985 to 2008. Results: Twenty-one patients were metastasis to ovary at the time of diagnosis of gastric cancer, and 34 patients were recurrent in ovary after the gastric resection. The mean age was 45.3 ± 11.6 years in metastatic cancer and 46.8 ±12.6 years in recurrent cancer patients. The stage at the time of gastric resection in 34 recurrent patients were I in 3, II in 1, III in 18, and IV in 10. Adjuvant chemotherapy were performed in 26 (76.5%) patients. Oophorectomy were performed in 33 (97.1%) of recurrent cancer, and 17 (81.0%) of metastatic cancer. The 1-year and 2-year survival rate of metastatic cancer were 14.7%, and 0%, and 1-year, 2-year, and 3-year survival rate of recurrent cancer were 47.2%, 18.1%, and 0%, respectively. The median survival duration of metastatic cancer were 8.9 ±1.0 months, and recurrent cancer were 11.4 ±2.3 months. Recurrent cancer were better survival than metastatic cancer patients (p=0.014). The long-term survival (over 2 years) was noted in 5 patients of recurrent cancer patients. The stage of gastric cancer was correlated to overall survival time in total patients (p=0.028). But, the relapse-free survival time after gastrectomy is the only factor to predict survival duration after oophorectomy in recurrent cancer patients (p=0.029). Age, stage of gastric cancer, extent of involvement of ovary, and systemic chemotherapy were not related to survival time of recurrent cancer patients. Conclusions: The survival time in patients with oophorectomy in recurrent gastric cancer was correlated to relapse-free survival time after gastric resection. No significant financial relationships to disclose.

3538 Background: CRC liver metastases can be resected after downsizing with intensive chemotherapy schedules, with a strong correlation between the response and resection rates. Cetuximab plus chemotherapy has been shown to increase the rates of tumor response and resection of liver metastases. (Van Cutsem et al, JCO 2011). Methods: Patients (pts) with technically non-resectable and/or with > 4 liver metastases were randomized to treatment with FOLFOX/cetuximab (arm A) or FOLFIRI/cetuximab (arm B) and evaluated regarding resectability every 2 months. Resection was offered to all patients who became resectable during the study. K-ras and b-raf status were retrospectively evaluated. Data on tumor response and resection were reported earlier (Folprecht et al, Lancet Oncol 2010). Overall and progression free survival were analyzed in December 2012. Results: Between Dec 2004 and March 2008, 56 pts were randomized to arm A, 55 to arm B. For the current analysis, 109 pts were evaluable for overall survival (OS), and 106 patients for PFS. The median OS was 35.7 [95% CI: 27.2-44.2] months (arm A: 35.8 [28.1-43.6], arm B: 29.0 [16.0-41.9], HR 1.03 [0.66-1.61], p=0.9). The median PFS was 10.8 [9.3-12.2] months (Arm A: 11.2 [7.2-15.3], Arm B: 10.5 [8.9-12.2], HR 1.18 [0.79-1.74], p=0.4). Patients with R0 resection had a better OS (median: 53.9 [35.9-71.9] mo) than patients without R0 resection (27.3 [21.1-33.4] mo, p=0.002) and a better PFS (median 15.4 [11.4-19.5] and 8.9 [6.7-11.1] mo in R0 resected and not R0 resected pts, p<0.001). The 5 year survival in R0 resected patients is 46.2% [29.5-62.9%]. Conclusions: This study confirmed a favourable long term survival of patients with initially “nonresectable” CRC liver metastases treated in a multidisciplinary approach of neoadjuvant chemotherapy with cetuximab and subsequent metastasectomy in pts who became resectable.

e20043 Background: MALTomas are extranodal marginal zone lymphomas that arise from B cells in various mucosal lymphoid tissue and are typically indolent. Patients with MALTomas may be at risk for additional cancers due to their long-term survival following treatment, however the incidence of SPM in MALTomas in the U.S. has not been previously described. Methods: Adults with MALT lymphoma were identified using the 2000-2016 SEER-18 database. SPM was defined as tumors diagnosed ≥6 months and up to x months from lymphoma diagnosis. SEER*stat was used to calculate SPM by multiple primary standardized incidence ratio based on observed (O) and expected (E) cases. The expected cases of new cancers of specific types were estimated by assuming that incidence rates for new primary tumors corresponded to sex, age, and calendar time–specific SEER rates for similar invasive primary cancers and applying those rates to the accumulated person-years (PYR) of observation. Excess absolute risk (EAR) of malignancy per 10,000 PYR at risk was calculated as ([O − E]/PYR) × 10,000. Results: As summarized in the table, 12,500 patients were diagnosed with MALT lymphoma of which 1466 (11.8%) developed 1626 SPMs (O/E rate 1.5, 95%CI 1.4-1.5, P < 0.001, EAR 70.4). Median latency period was 54 months (range 6 - 201). Non-Hodgkin lymphomas at separate tissue sites were the most common SPM, with 299 documented cases (O/E rate 6.2, 95%CI -5.4-6.8, P < 0.001, EAR 33.4). Between 6-24 months from MALToma diagnosis, head and neck, renal cell, liver, and anal cancers were increased, while after 24 months, gastric and small bowel cancers, CLL, ALL, and myeloma were increased compared to the general population of the same age group. Conclusions: There is distinct pattern of SPM among patients with MALT lymphoma in within and after 2 years from diagnosis, with an increased incidence compared to the general population. Consider the median latency, SPM may be due in part to the long-term survival and relatively older age of this population. [Table: see text]

22 Background: Survival is the ultimate end-point in field of medical oncology. Although tumor response has been used as surrogate end-point in early phase clinical trial in patients with gastric cancer, clear correlation between tumor response and long-term survival has not been established yet. The objective of the current study is to determine whether early assessment could predict survival in patients with AGC. Methods: A total of 337 patients with AGC who had participated one of the three first-line, prospective, investigator-initiated, randomized trials carried out in Yonsei Cancer Center were included in the analysis. 238 had received fluoropyrimidine (F) + platinum (P), 61 had received F + taxane (T), 38 had received T + P. Response was assessed according to RECIST 1.1 at 8, 14 and 20 weeks after initiation of treatment. The correlation between response at each time point and the OS was evaluated using logistic regression test. Results: The median OS was 13.7 months. (95% CI 11.8 – 15.6) In terms of confirmed tumor response, 1 CR, 84 PRs, 104 SDs and 148 PDs were observed. At every landmark period, disease control rate (DCR, CR + PR + SD) was superior in predicting OS comparing with response rate. (RR, CR + PR) (Table). Among them, 8-week DCR was the most powerful predictor for OS. (HR 0.18, p< .001) There was no significant OS difference between patients with (13.7 months) vs. without (13.9 months) measurable lesions (p = .705) and between patients with 8-week response of PR (18.1 months) vs. SD (15.3 months) (p = .522). Conclusions: Disease control was a better predictor for OS in patients with AGC who had received first-line chemotherapy than response, with disease control at 8 week being the most powerful predictor. This could be used as a surrogate marker for long-term survival in early phase clinical trials. [Table: see text]

11041 Background: A subset of metastatic GIST exhibit very long-term survival after imatinib (IM) introduction. The aim of this study was to analyse the clinico-biological characteristics of GIST pts alive > 10 years (yrs) after diagnosis (dx) of metastases (mets) and identify possible factors associated with long-term survival. Methods: Pts were identified from 2 sarcoma databases; NetSarc and ConticaGIST. Clinical data prospectively registered in the databases were supplemented with retrospective review of medical records. Results: We identified 141 pts (75 men, 66 women) with median age 54 (17-84) yrs and median ECOG 0 (0-2). Primary tumors (T) were all CD117+, and mainly gastric or intestinal (64 & 45 pts), with median size 10 (2-40) cm, CD34+ (82 pts), mitoses/50 HPF ≤ 5 (n = 36), or > 5 (n = 81). Genotype was documented in 82 (58%) pts with 73 (89%) KIT mutations (in exons 11,9 and 12 of 69, 3, and 1 pts respectively) and 9 WT KIT. 129 (91%) T were resected, 124 upfront, 5 post IM, with R0/R1/R2 resections in 61, 11, and 10 pts. Mets were mainly hepatic or peritoneal (78 & 51 respectively). 1st line TKI was given to 139 pts: 130 received IM; 88 (63%) within a clinical trial (CT), 41 (29%) had mets resection. Second, 3d and 4th line TKI were given to 81, 51 and 37 pts respectively, comprising 27, 7 and 10 from CT. Median number of TKIs was 2 (0-7), but 60 (44%) pts received only 1st line with no GIST progression within or after 10 yrs. 2 pts never received TKI but had mets resection. After median FU of 14.3 yrs (10-34.5), 104 remain alive, 37 died. Mean and Median OS from initial dx are 24 yrs (CI95% 21.6-27) and 20,8 yrs. Median PFS on TKIs are 127, 29, 21 and 22 mos on 1st, 2d, 3d and 4th line of TKI. In univariate analysis no factor is significantly associated with OS, but T size (≤ 10 vs > 10 cm) and oligometastatic disease (≤5 vs > 5 mets) are borderline significant (p = 0.056 and 0.07), and good PS (ECOG ≤ 1) at 2dline TKI initiation is associated with better PFS (p = 0.03). Conclusions: This large series of long-term ( > 10 yrs) survivors of metastatic GIST shows a high proportion of mets resection and a longer duration of PFS for TKI at any line. In this selected population, no prognostic factor is associated with long OS.

Purpose: Improved survival after liver resection for breast cancer liver metastases (BCLM) has been proven; however, there is still controversy on predictive factors influencing outcomes. The analysis of factors related to primary and metastatic cancer eventually influencing long-term outcomes and a review of the literature are presented in this report. Methods: Twenty-seven patients diagnosed with metachronous BCLM between 1996 and 2013 were retrospectively reviewed. Patients who had a minimum disease-free interval between primary tumor and liver metastasis of 12 months, no more than 3 liver lesions, no macroscopic extra-hepatic disease and in which systemic therapy showed a good response were included. Results: Twenty-two patients (82%) were initially diagnosed with a stage I-II disease. Twelve patients presented with multiple liver metastases. The 5 years overall survival (OS) rate was 78%, while the 5 years disease-free survival (DFS) rate was 36%. Initial tumor stage III-IV at first diagnosis and number of metastases >1 was significantly associated with a shorter DFS at multivariate analysis (p = 0.03 and p = 0.04 respectively). Patients with multiple lesions had a median DFS of 15 months compared to 47 months in patients with a single lesion (p = 0.03). Conclusions: Resection of single BCLM from primary stage I-II cancer offers very good long-term survival rates and a low morbidity.
