Background: Open partial laryngeal surgery (OPLS) represents a wide array of procedures that can be fitted to treat different types of laryngeal cancer (LC). We would like to present our 30-years’ institutional experience, to analyze survival outcomes and to critically discuss prognostic factors. Methods: We reviewed all cases of OPLS performed at our Institution from 1982 to 2016 for LC. Survival analysis by Kaplan–Meier estimate was performed and prognostic variables by multivariate analysis were identified. Results: Mean follow-up time was 68.3 months, 30-day mortality 0.2%, subsequent functional total laryngectomy (TL) was 1.01%. Over 80% of cases were stage I to II. We had 25 local, 62 regional and eight distant recurrences. Local control was 94.9%, overall survival (OS) was 83.4% and disease-specific survival (DSS) was 87.7%. The two major risk factors significantly associated with the risk of death were cT and cN stage. CONCLUSIONS: We have confirmed that OPLS represents an oncologically sound option in the treatment of LC despite the emergence of non-surgical strategies and new transoral mininvasive techniques. Our results highlight that accurate staging, correct selection of the patient and a strong surgical expertise are of paramount importance in this type of surgery.

8023 Background: t(11;14) is a common cytogenetic abnormality historically associated with standard-risk and generally favorable MM outcomes, but has shown poor prognosis in some retrospective analyses. Connect MM is a prospective, US, observational, multicenter registry that collects data on management and natural history of NDMM pts in clinical practice. The impact of t(11;14) on survival outcomes was assessed in AA and NAA pts. Methods: Adult NDMM pts who completed induction and were tested for t(11;14) by FISH/cytogenetics were grouped by race (AA vs NAA). Endpoints were PFS and OS. Kaplan-Meier analyses were adjusted for differences in cohort, age, ISS stage, transplant intent, t(4;14), hemoglobin, platelets, calcium, creatinine, and diabetes history. Data cutoff was Jul 7, 2016. Results: 3011 pts were enrolled in 2 cohorts (Cohort 1: n = 1493, Sep 2009–Dec 2011, median follow-up = 39.3 mos; Cohort 2: n = 1518, Dec 2012–Apr 2016, median follow-up = 16.4 mos). Of 1539 (52%) pts tested for t(11;14), 363 (24%) were t(11;14)-positive, including 53 (26%) of 205 AA and 310 (23%) of 1334 NAA pts. First-line bortezomib exposure was similar across groups. A trend of shorter PFS was observed in AA pts with t(11;14) vs AA without t(11;14) (Table). AA pts with t(11;14) had significantly higher risk of death compared to those without t(11;14) and higher rate of early mortality than NAA pts. No differences in PFS or OS were noted in NAA pts with or without t(11;14). For OS, the interaction between race and t(11;14) status was statistically significant ( P= 0.004). Conclusions: In Connect MM, the effect of t(11;14) on OS was significantly different between AA and NAA pts. t(11;14) was associated with poorer survival outcomes in AA pts, and thus, may be a risk factor for poor prognosis. Additional analyses will be conducted to elucidate the role of induction treatment, transplant and maintenance in AA and non-AA pts with t(11;14). Clinical trial information: NCT01081028.

Abstract Backgroud: Squamous cell carcinoma (SCCA) is the most common vulva cancer. This study purpose to evaluate the clinicopathological prognostic factors for survival outcomes of this disease after treated with surgery. Methods: All SCCA vulva cancer patients who underwent surgery between January 2006 and December 2017 were reviewed. The clinicopathological factors were analyzed to identify the prognostic factors for the progression-free survival (PFS) and overall survival (OS) using the Kaplan- Meier method and Cox-Proportional Hazard model.Results: One hundred twenty-five patients were recruited with a median age of 57 years. The recurrence rate was 35.2%. Patients with recurrence revealed a significant poorer five-year OS rate than those who did not recur (23.7% vs. 79.4%, P < 0.001). About 58.1% of palpable groin nodes revealed metastasis. The independent poor prognostic factors for PFS were groin node-positive and a tumor diameter more than 25 mm. whereas postmenopausal status, preoperative tumor area more than 11 cm2, and groin node enlargement were independent poor prognostic factors for OS. Conclusion: Groin node-positive and tumor diameter longer than 25 mm. were independent poor prognostic factors for PFS whereas postmenopausal status, large tumor area than 11 cm2, and enlargement of groin nodes were independent poor prognostic factors for OS. Patients with these factors should be closely followed.

Abstract Background Atezolizumab (ATZ) has demonstrated antitumor activity in the previous studies in patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of ATZ was modest. Therefore, finding biologic or clinical biomarkers that could help to select patients who respond to the immune checkpoint blockade remains important. Patients and Methods In this study, we present the retrospective analysis of 105 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of patients were obtained from patient files and hospital records. The association between response to first-line chemotherapy and ATZ was using Fisher’s exact test. Median follow-up was calculated using the reverse Kaplan-Meier method. OS was estimated by using the Kaplan-Meier method. Results The median follow-up time was 23.5 months. Forty (74.1%) of patients who experienced clinical benefit after firs-line chemotherapy also had clinical benefit after atezolizumab, while only 14 (25.9%) of patients with initial PD after first-line chemotherapy subsequently experience clinical benefit with ATZ (p = 0.001). The median OS on ATZ of 14.8 and 3.4 months for patients with clinical benefit and progressive disease in response to first-line chemotherapy, respectively (p = 0.001). Three of the adverse prognostic factors according to the Bellmunt criteria were independent factors of short survival: liver metastases (Hazard Ratio [HR] = 1.9; p = 0.04), ECOG PS ≥ 1 (HR = 2.7; p = 0.001), and Hemoglobin level below 10 mg/dl (HR = 2.8; p < 0.001). In addition, patients with clinical benefit from first-line chemotherapy (HR = 0.39; p < 0.001) maintained a significant association with OS in multivariate analysis. Conclusions Our study demonstrated that clinical benefit from first-line chemotherapy was independent prognostic factors on OS in patients' use of ATZ as second-line treatment in metastatic bladder cancer. Furthermore, these findings are important for stratification factors for future immunotherapy study design in patients with bladder cancer who have progressed after first-line chemotherapy

Abstract INTRODUCTION Despite increasing use of stereotactic radiosurgery (SRS) for management of brain metastases (BM), published Australian data is scarce. We aim to report on the outcomes following SRS for limited BM in a single Australian institution. METHODS This is a retrospective cohort of patients with limited BM treated with SRS between August 2015 and March 2019. A dose of 24Gy/3# were prescribed to intact lesion, and 21Gy/3# to surgical cavity post-surgical resection. All patients were followed with 3-monthly surveillance MRI brain. Primary outcomes were: local failure (LF: increased in size of SRS-treated BM lesion/ recurrence in surgical cavity), distant failure (DF: intracranial progression outside of the SRS-treated lesion/ cavity), and overall survival (OS). LF, DF and OS were estimated using the Kaplan-Meier method. Multivariate Cox regressions were used to evaluate factors associated with outcomes of interest, with death as competing-risk events for LF and DF. RESULTS 76 courses of SRS were delivered in 65 patients (54 unresected BM lesions, and 22 surgical cavities). 43 (66%) patients were ECOG 0–1. 35 (54%) patients had solitary BM. 41 (63%) had symptomatic BM. Half of the patients had primary lung cancer. Median follow-up was 4.8 months (range:0.1–39 months). 10 LF were observed at a median of 3.5 month post-SRS, with 6- and 12-month LF cumulative incidence of 14% and 24% respectively. 30 DF were observed at a median of 3.3 months, with 6- and 12-month DF cumulative incidence of 38% and 63% respectively. The 12- and 24-month OS were 39% and 26% respectively. In multivariate analyses, better ECOG status, solitary BM lesion, resection of BM pre-SRS, and use of subsequent systemic therapy were independently associated with improved OS. CONCLUSION This is one of the few Australian series reporting on outcomes following SRS for limited BM, with comparable outcomes to published international series.

ObjectivesThis study sought to investigate the relationship between occlusion length and long-term outcomes of patients with recanalised chronic total occlusion (CTO) lesion.DesignA retrospective cohort study.SettingFuwai Hospital, National Center for Cardiovascular Disease, Beijing, ChinaParticipantsConsecutive patients with successfully recanalised CTO were included from January 2010 to December 2013.Primary and secondary outcome measuresThe primary endpoint of the present study was a composite event of all-cause death and myocardial infarction (MI). The secondary endpoints included target lesion revascularisation (TLR) and target vessel revascularisation (TVR).ResultsA total of 1987 patients were included and 1801 (90.6%) subjects completed 5-year follow-up in this study. Based on occlusion length, the patients were divided equally into two groups: short (length <15 mm, n=957) and long (length ≥15 mm, n=1030) CTO group. Kaplan-Meier survival curve showed no significant difference in the risk of the composite primary endpoint between short and long CTO groups (p=0.242). Receiver operating characteristic curve analysis also established occlusion length ≥15 mm as a cut-off value for predicting TLR and TVR, with an area under the curve of 0.604 (95% CI: 0.569 to 0.638, p<0.001) and 0.605 (95% CI: 0.572 to 0.638; p<0.001). Kaplan-Meier analysis revealed that the risks for TLR (p=0.002) and TVR (p=0.002) were higher in a patient with long CTO lesion. Multivariate Cox analysis also identified long CTO lesion as an independent predictor of TLR (HR: 1.539, 95% CI: 1.033 to 2.293; p=0.034) and TVR (HR: 1.476, 95% CI: 1.012 to 2.151; p=0.043).ConclusionPatients with long CTO lesion did not show a higher risk of death and MI after recanalisation, but had higher risks of TLR and TVR. Lesion with occlusion length ≥15 mm should be under close surveillance for restenosis after recanalisation.

Background. In gastric cancer, various surveillance strategies are suggested in international guidelines. The current study is intended to evaluate the current strategies and provide more personalized proposals for personalized cancer medicine. Materials and Methods. In the aggregate, 9191 patients with gastric cancer after gastrectomy from 1998 to 2009 were selected from the Surveillance, Epidemiology, and End Results database. Disease-specific survival was analyzed by Kaplan-Meier method and the log-rank test. Cox proportional hazards regression analyses were used to confirm the independent prognostic factors. As well, hazard ratio (HR) curves were used to compare the risk of death over time. Conditional survival (CS) was applied to dynamically assess the prognosis after each follow-up. Results. Comparisons from HR curves on different stages showed that earlier stages had distinctly lower HR than advanced stages. The curve of stage IIA was flat and more likely the same as that of stage I while that of stage IIB is like that of stage III with an obvious peak. After estimating CS at intervals of three months, six months, and 12 months in different periods, stages I and IIA had high levels of CS all along, while there were visible differences among CS levels of stages IIB and III. Conclusions. The frequency of follow-up for early stages, like stages I and IIA, could be every six months or longer in the first three years and annually thereafter. And those with unfavorable conditions, such as stages IIB and III, could be followed up much more frequently and sufficiently than usual.

Aim. This study aimed to retrospectively compare the survival outcomes over two years between teeth with proximal dental caries that were restored with stainless-steel crowns to those that were pulpotomized and then restored with a stainless-steel crown in patients who were rehabilitated under general anesthesia. Participants and Methods. The records of 131 patients aged between two to six years who had stainless-steel crowns placed under general anesthesia and had two-year follow-up were screened. 340 teeth with moderate proximal caries on the radiograph (D2) were included in the study. Of these, 164 teeth were treated with a pulpotomy and stainless-steel crown, while 176 teeth were crowned without a pulpotomy. The type of each tooth was compared using the Chi-squared test and Kaplan–Meier survival analysis, and curves were plotted based on the two-year outcomes. Results. Treatment: the sample comprised 59 males (mean age 4.73 years, SD ± 1.4 years) and 72 females (mean age 5.2 years, SD ± 2.0 years). The Kaplan–Meier regression model showed no significant difference in survival outcomes between teeth that had been pulpotomized and those that had not ( p  = 0.283). Conclusion. Within the limitations of the current study, we can conclude that performing a pulpotomy does not influence the survival outcome of mild/moderate proximal caries restored with stainless-steel crowns under general anesthesia.

Abstract Background This retrospective analysis was undertaken to evaluate the efficiency of SIRT with Y-90 microspheres and determined prognostic factors affecting patients with unresectable HCC. Methods A total of 97 patients diagnosed with unresectable HCC who underwent SIRT with Y-90 microspheres. Patient survival was assessed using the Kaplan–Meier method, and prognostic factors affecting survival were assessed using log-rank tests and Cox proportional hazards regression. Results Among the 97 patients (90 males, mean age 60.4 ± 12.3 years) who underwent SIRT, the median clinical follow-up was 16.4 (1.8–62) months. The median overall survival (OS) was 23.9 ± 2.4 months. Tumor response according to the Modified RECIST in patients followed up beyond 6 months included a complete response (CR) to treatment in 12 patients (18.8%), partial response (PR) in 23 (35.8%), stable disease (SD) in 8 (12.5%), and progressive disease (PD) in 21 (32.8%). Factors associated with longer OS included age > 65 years, BCLC stage B, tumor size < 5 cm, tumor burden < 25%, and tumor response (CR/PR). In multivariate analysis, unilobar disease and objective tumor response (CR/PR) were predictors of longer OS. Conclusion SIRT was an effective treatment for unresectable HCC. Unilobar disease before SIRT and tumor response (CR/PR) were positive prognostic factors.

9097 Background: Localized cutaneous melanomas (CM) have their clinical course predicted by microscopic findings in the tumor specimen, mostly Breslow’s thickness (BTL), ulceration and mitoses. It is not certain whether BTL has a linear relationship with overall survival (OS) or relapse-free survival (RFS). The aim of this study was to evaluate BTL´s linear (LC) and its non-linear component (NLC) with relation to survival. Methods: All consecutive cases of CM treated from 1997 to 2006 at a single institution were identified, individuals with stage I or II tumors, minimum follow up of one month and known BTL were selected, socio-demographic data, clinical and pathological findings, treatment and outcomes were abstracted. Information about ulceration was missing in more that 30% of cases and it was not evaluated, there was no information about mitotic rate. Survival was estimated by the Kaplan-Meier method. Multivariate analyses were performed by the Cox model. BTL was evaluated as a continuous variable, and the LC and NLC by the technique of smoothing, using p-splines. Results: There were 1465 cases of CM, 51 with no follow up, 137 had no information about BTL and 202 had advanced stages. This analysis is based on 1075 cases. In the Cox model, the variables associated OS were age [hazard ratio (HR) 1.02, 95% CI 1.01 to 1.03], sex (HR 1.56, 95% CI 1.2 to 2.04) and BTL (HR=1.079, 95% CI 1.065 to 1.094). The variables associated with RFS were age (HR 1.017, 95% CI 1.009 to 1.024), sex (HR 1.372, 95% CI 1.104 to 1.704) and BTL (1.068, 95% CI 1.057 to 1.080). In the analysis of LC and NLC of BTL, it was found that both LC and NLC were statistically significant for OS and RFS. There was an increase in the HR as BTL increased in those lesions thinner than 4mm, then such increase was not as evident and lesions with more than 10mm had a similar OS and RFS (plateau). Conclusions: BTL is one of the most powerful prognostic criteria of patients with stage I and II CM. The risk of death increases linearly for thin lesions up to 4mm, lesions thicker than 10mm behave as a uniform group with no further decrease in OS or RFS as the lesion becomes larger. In conclusion, BTL may not behave as a linear function, it has a LC for thinner lesions, but for thicker lesions, above 10mm, further increase in BTL may add no more risk.

559 Background: The increase in survival seen in recent years in patients with mCRC has been attributed to improvements in treatments, including the introduction of targeted biologic agents. The objectives of this retrospective, observational study are to investigate recent treatment patterns in US mCRC patients and examine real-world survival outcomes. Methods: Data were obtained from a large U.S. database (SDI/IMS Health) of mCRC patients diagnosed from January 1, 2004 to June 30, 2011, ≥18 y at diagnosis, and who received chemotherapy and/or biologic treatment. Complete follow-up was defined as those who either died before June 2011 or who had at least 1 claim within 30 days of June 30, 2011. Kaplan-Meier curves were generated to determine overall survival (OS) from the date of mCRC diagnosis. Results: 1,066 stage IV mCRC patients with complete follow-up were identified (57.5% male; mean age, 61.6 y). Approximately 80% were diagnosed with mCRC after 2006; 51.7% had liver metastases. The most common 1L, 2L, and 3L regimens were FOLFOX plus bevacizumab (34.52%), FOLFIRI plus bevacizumab (21.83%), and irinotecan plus cetuximab (15.83%), respectively. A total of 445 patients died during the study period, yielding a mortality rate of 41.74%. Mean time from diagnosis to first treatment was 3.31 months (SD=7.13). All patients received 1L therapy; OS from diagnosis was 35.77 months (95% CI: 32.57-38.10); 5-year survival was approximately 28%. After 1L, 591/1066 (55%) patients went on to receive 2L therapy; for these patients, median survival from diagnosis was 37.13 months (95% CI: 34.07-40.43) and 5-year survival was approximately 25%. After 2L, 278/591 (47%) patients received 3L therapy; for these patients, median survival from diagnosis was 38.10 months (95% CI: 34.83-43.13); 5-year survival was approximately 25%. Conclusions: In this study, OS (35.77 months) was longer than for other mCRC observational studies that have reported survival from start of treatment, but is more comparable when the ~3 months from diagnosis to start of treatment are not included. Addition of targeted agents and novel chemotherapy has prolonged OS in mCRC patients. Because of poor 5-year survival rates, the need for additional agents in later lines of therapy still exists.
