The optimal tumor marker for predicting the prognosis of advanced thymic carcinoma (ATC) remains unclear. We conducted a multi-institutional retrospective study of patients with ATC. A total of 286 patients were treated with chemotherapy. Clinicopathological information, including serum tumor markers, was evaluated to determine the overall survival (OS) and progression-free survival (PFS). The carcinoembryonic antigen, cytokeratin-19 fragment, squamous cell carcinoma (SCC) antigen, progastrin-releasing peptide, neuron-specific enolase (NSE), and alpha-fetoprotein levels were evaluated. In the Kaplan–Meier analysis, the OS was significantly shorter in the patients with elevated NSE levels than in those with normal NSE levels (median, 20.3 vs. 36.8 months; log-rank test p = 0.029; hazard ratio (HR), 1.55; 95% confidence interval (CI), 1.05–2.31 (Cox proportional hazard model)); a similar tendency regarding the PFS was observed (median, 6.4 vs. 11.0 months; log-rank test p = 0.001; HR, 2.04; 95% CI, 1.31–3.18). No significant differences in the OS and PFS were observed among the other tumor markers. In both univariate and multivariate analyses of the patients with SCC only, the NSE level was associated with the OS and PFS. Thus, the NSE level may be a prognostic tumor marker for thymic carcinoma, regardless of histology.

Purpose. This study retrospectively evaluated overall survival (OS) by treatment of recurrent or metastatic uterine adenosarcoma including surgery, radiation, chemotherapy, and hormonal therapy and evaluated OS and progression-free survival (PFS) after 1st line systemic chemotherapy. Methods. 78 patients with recurrent or metastatic adenosarcoma comprised the study population. The Kaplan-Meier method was used to estimate OS and PFS. The log-rank test was performed to test the difference in survival between groups. Results. Median OS from diagnosis of recurrent or metastatic disease was 1.8 yrs. OS was influenced by pathology on recurrence, p=0.035. Median OS differed by surgery for 1st recurrence 26.3 months versus 15.1 months. OS was not influenced by chemotherapy, p=0.58, palliative radiation, p=0.58, or hormonal therapy, p=0.15. The response rate (CR + PR) per RECIST 1.1 for chemotherapy was 31.2% for doxorubicin-based regimens and 14.3% for gemcitabine/docetaxel. OS since 1st line chemotherapy was not significantly different among chemotherapy regimens. However, the median PFS was superior for doxorubicin/ifosfamide (15.4 months) compared to gemcitabine/docetaxel (5.0 months), platinum-based regimens (5.7 mo), or other doxorubicin-based regimens (6.5 months). Conclusion. These results suggest that surgery is an important treatment modality for recurrent or metastatic uterine adenosarcoma, and the most effective chemotherapeutics are doxorubicin/ifosfamide and gemcitabine/docetaxel.

Aim: Although, the effectiveness of metformin in diabetes treatment is well established, its preventive effect in the development of diabetes is still unclear in real world. We aimed to determine the effectiveness of metformin therapy as a single preventive agent in patients with prediabetes in a cohort study (IDPS). Study Design: In this prospective observational study. Place and Duration of Study: Isfahan Endocrine and Metabolism Research Center, Isfahan University of Medical Sciences, Isfahan, Iran. Methodology: We included 410 patients with prediabetes (168 metformin user, 242 non-users), who participated in IDPS. To determine the association between metformin use and incidence of type 2 diabetes, Cox proportional hazard method, Kaplan-Meier and log Rank test were used. Results: In fully adjusted model for all confounders, significant hazard ratio (HR) for staying prediabetes rather than returning to normal was detected in male group of metformin non-user (HR: 2·41 [95% CI 1.01-5.79]; P<0·05) and those metformin non-user who had both Impaired Fasting Glucose and Impaired Glucose Tolerance (IFG & IGT) (HR: 2.13 [95% CI 1.05-4.34]; P=0·04).  There was no significant difference in terms of developing diabetes risk between metformin users and non-users. Conclusion: This study evidenced that males and patients with IFG & IGT who had not used metformin are at higher risk to staying prediabetes than returning to normal.

e13006 Background: The 5-year survival for patients (pts) with glioblastoma (GBM) is low at approximately 3%. Radiotherapy plus concomitant and adjuvant temozolomide (TMZ) remain the standard of care. The optimal duration of therapy with TMZ is unknown, though treatment periods of 6 months (mo), 12 mo and longer have been utilized. Whether or not there is a benefit with longer treatment duration is controversial. Methods: A retrospective chart review of all pts diagnosed with GBM who were treated at a regional referral center was conducted with data obtained from their electronic medical records. These pts were treated with TMZ for up to 2 years between January 1, 2002 and December 31, 2011. Survival was calculated as the time from initial surgical diagnosis until death. The Kaplan-Meier method with log-rank test was used to estimate the progression-free survival (PFS) as well as the overall survival (OS) distribution of pts after treatment. The results were compared to historical controls and data from previous clinical trials of pts treated up to 1 year. Results: Data from 56 pts were evaluated, the majority of whom had gross total resection and had external pathology review confirming the diagnosis of GBM. The OS probability was 55.4% (SE = 0.068) at 1 year, 26.9% (SE = 0.067) at 2 years and 20.1% (SE = 0.065) at 3 years. The median PFS time in this study group was 8 mo (95% CI = 4.0 – 9.0 mo). The probability of no progression at 2 years was 8.6% (SE = 0.05). Seven pts (12.5%) were treated with TMZ for 2 years. The probability of disease progression at 2 years among these pts was 33.3% with a median time-to-progression of 20 mo (95% CI = 5.0-28.0). These patients showed an increased survival probability at 3 years compared to pts who did not receive the 2 year treatment of TMZ (log-rank test Chi-square = 12.4, p = 0.0004). Conclusions: This analysis suggests that there may be an advantage for a longer duration of TMZ therapy in pts with GBM. In this review, treatment with TMZ for 2 years was associated with an increased survival benefit. While we consider the sample size to be too small for generalization, a prospective/multicenter study with a larger sample size might better evaluate the question of duration of TMZ therapy, particularly if both clinical and basic science data are paired.

e18125 Background: Platinum based regimens are standard first-line treatment in patients with advanced non mall cell lung cancer. We intend to evaluate their effectiveness according to the number of cycles administered, and investigate whether histology is a predictor of benefit from a greater number of infusions. Methods: 124 patients with stage IV NSCLC were evaluated retrospectively. They were divided according to whether they made 4 or 6 cycles of chemotherapy. The schemes used were: Cisplatin / Gemcitabine and Carboplatin / Paclitaxel, at standard doses. We studied the efficacy in both groups according to the most common histologies (adenocarcinoma and squamous cell carcinoma). PFS (progression-free survival) and OS (overall survival) were calculated by the Kaplan-Meier curves and compared by the Log Rank Test. Results: Those who underwent 4 cycles had a PFS of 7.77 months and OS of 12.2 months vs. 8.64 and 10.8 months those who received 6 cycles (p = 0.47, p = 0.76). Within the subgroup with squamous histology (n = 43), PFS and OS were 7.38 and 13.38 months respectively in the group that received 4 cycles vs. 7.97 and 9.76 months in those receiving 6 (p = 0.70, p = 0.32 ). Within adenocarcinoma histology (n = 81), those who received 4 cycle, has a PFS of 8.17 months and they lived 11.56 month, vs 8.96 and 10.79 months for those receiving 6 cycles (p = 0.29, p = 0.88) Conclusions: In our population, a greater number of cycles showed no advantages in terms of progression-free survival or overall survival. Histology is not a predictive factor for deciding how many chemotherapy cycles administer.

Pendahuluan. Pengaruh revaskularisasi terhadap kesintasan pasien non ST elevation myocardial infarction (NSTEMI) masih belum jelas. Waktu revaskularisasi yang optimal pada pasien NSTEMI belum ditemukan. Penelitian ini bertujuan mengetahui pengaruh revaskularisasi terhadap kesintasan pasien NSTEMI, juga mengetahui pengaruh waktu revaskularisasi terhadap kesintasan pasien NSTEMI.Metode. Penelitian dengan disain kohort retrospektif dilakukan terhadap 300 pasien non ST elevation myocardial infarction yang dirawat di RSUPNCM pada kurun waktu Desember 2006-Maret 2011. Data klinis, laboratorium, elektrokardiografi (EKG), ekokardiografi, dan angiografi koroner dikumpulkan. Pasien yang telah terhitung enam bulan setelah onset kemudian dihubungi melalui telepon untuk melihat status mortalitasnya. Perbedaan kesintasan revaskularisasi ditampilkan dalam kurva Kaplan Meier dan perbedaan kesintasan diantara dua kelompok diuji dengan Log-rank test dengan batas kemaknaan <0,05, serta analisis multivariat dengan Cox proportional hazard regression untuk menghitung adjusted hazard ratio (dan interval kepercayaan 95%) antara pasien NSTEMI yang menjalani terapi medikamentosa dan revaskularisasi terhadap kelompok medikamentosa dengan memasukkan variabel perancu.Hasil. Terdapat perbedaan kesintasan yang bermakna pada uji log rank (p<0,001) antara pasien NSTEMI yang menjalani revaskularisasi dan terapi medikamentosa saja dengan crude HR 0,19 (IK95% 0,11-0,34) dan fully adjusted HR 0,33 (IK95% 0,17-0,64). Faktor perancu yang bermakna adalah penurunan fungsi ginjal dan syok kardiogenik. Pada analisis kesintasan berdasarkan waktu revaskularisasi tidak didapatkan perbedaan kesintasan antara pasien yang menjalani revaskularisasi < 1 minggu, 1-2 minggu, 2-3 minggu, 3-4 minggu, 4-5 minggu dengan p=0,853.Simpulan. Kesintasan enam bulan pasien NSTEMI yang menjalani terapi medikamentosa dan revaskularisasi lebih baik dibandingkan dengan terapi medikamentosa saja. Tidak terdapat perbedaan kesintasan enam bulan pasien NSTEMI berdasarkan waktu revaskularisasi.

Introduction The five-year survival rate for patients with glioblastoma (GBM) is low at approximately 4.7%. Radiotherapy plus concomitant and adjuvant temozolomide (TMZ) remains the standard of care. The optimal duration of therapy with TMZ is unknown. This study sought to evaluate the survival benefit of two years of treatment. Methods This was a retrospective chart review of all patients diagnosed with GBM and treated with TMZ for up to two years between January 1, 2002 and December 31, 2011. The Kaplan-Meier method with log-rank test was used to estimate the progression-free survival (PFS) and the overall survival (OS). The results were compared to historical controls and data from previous clinical trials of patients treated up to one year. Results Data from 56 patients with confirmed GBM were evaluated. The OS probability was 54% (SE = 0.068) at one year, 28.3% (SE = 0.064) at two years, 17.8% (SE = 0.059) at three years, and 4% (SE = 0.041) at five years. Seven patients (12.5%) were treated with TMZ for two years. Their median time-to-progression was 28 months (95% CI = 5.0 - 28.0), and they had an increased survival probability at three years compared to other patients (log-rank test χ2 (1, N = 56) = 19.2, p < 0.0001). Conclusions There may be an advantage for a longer duration of TMZ therapy among patients with GBM, but the sample size was too small for generalization. A multicenter prospective study is needed to dentify optimal duration of TMZ therapy.

We performed a multi-institutional analysis of 74 children with ependymoma to evaluate to what extent the clinical outcome of prospective trials could be reproduced in routine practice. The evaluation of factors that correlated with outcome was performed with a log rank test and a Cox proportional-hazard model. Survival was estimated with the Kaplan–Meier method. The majority of patients had brain tumours (89%). All had surgery as primary treatment, with adjuvant radiotherapy (RTH) and chemotherapy (CTH) applied in 78% and 57%, respectively. Median follow-up was 80 months and 18 patients died. Five- and 10-year overall survival (OS) was 83% and 73%. Progression was observed in 32 patients, with local recurrence in 28 cases. The presence of metastases was a negative prognostic factor for OS. Five- and 10-year progression-free survival (PFS) was 55% and 40%, respectively. The best outcome in patients with non-disseminated brain tumours was observed when surgery was followed by RTH (+/−CTH afterwards; p = 0.0001). Children under 3 years old who received RTH in primary therapy had better PFS (p = 0.010). The best outcome of children with ependymoma is observed in patients who received radical surgery followed by RTH, and irradiation should not be omitted in younger patients. The role of CTH remains debatable.

The role of adjuvant therapy for malignant mixed müllerian tumors of the uterus has not been established. Our aim was to review our experience with sequential adjuvant therapy using cisplatin and ifosfamide chemotherapy and radiotherapy after surgical staging. A retrospective study of 43 patients from 1995 to 2004 was undertaken. Survival was calculated using the Kaplan–Meier method and compared by the log-rank test. The Cox proportional hazard regression model was used to assess the effect of treatment on survival after adjustment for age and stage. Twenty-eight patients received adjuvant chemotherapy and 28 patients had adjuvant radiotherapy. Twenty-one patients underwent sequential adjuvant chemotherapy and radiotherapy. Tumor recurrence occurred in 14 patients at a median duration of 10 months. The overall 2- and 5-year survival was 64% and 60%, respectively. The 2- and 5-year survival for stage I and II diseases was both 95%, while the 2-year survival for stage III and IV diseases was 25%. Patients who underwent sequential adjuvant therapy had an improved survival compared with patients who did not follow the protocol (P = 0.024). Our results with sequential adjuvant therapy are encouraging and justify future randomized trials.

612 Background: Ratios of neutrophils, monocytes, and platelets to lymphocytes (NLR, MLR, and PLR) are associated with poor CO in cancer pts. We investigated the association of NLR, MLR, and PLR and CO in mRCC pts treated with cabo. Methods: We performed a retrospective study of 65 mRCC pts treated with cabo at Winship Cancer Institute from 2016-2018. Overall survival (OS) and progression free survival (PFS) were calculated from first dose to date of death and radiographic or clinical progression, respectively. NLR, MLR, and PLR were obtained at baseline (BL) and 6 (±2) weeks (6W) after cabo initiation. Optimal cut (OC) was determined searching all cuts and testing them by bias adjusted log rank test to associate with PFS. Multivariate analysis (MVA) was performed using Cox proportional hazard model. Results: The medians were: 2.8 (NLR), 0.4 (MLR), and 176.7 (PLR). Increased NLR, MLR, and PLR were significantly associated with worse CO (Table). Conclusions: High NLR, MLR, and PLR may be poor prognostic factors in mRCC pts treated with cabo. Larger studies are needed to validate the results of this study. [Table: see text]

BackgroundImmune-Oncology (IO) improves Overall Survival (OS) in metastatic Renal Cell Carcinoma (mRCC). The prognostic impact of previous Cytoreductive Nephrectomy (CN) and radical nephrectomy (RN), with curative intent, in patients treated with IO is not well defined. The aim of our paper is to evaluate the impact of previous nephrectomy on outcome of mRCC patients treated with IO.Methods287 eligible patients were retrospectively collected from 16 Italian referral centers adhering to the MeetUro association. Patients treated with IO as second and third line were included, whereas patients treated with IO as first line were excluded. Kaplan–Meier method and log-rank test were performed to compare Progression Free Survival (PFS) and OS between groups. In our analysis, both CN and RN were included. The association between nephrectomy and other variables was analyzed in univariate and multivariate setting using the Cox proportional hazard model.Results246/287 (85.7%) patients had nephrectomy before IO treatment. Median PFS in patients who underwent nephrectomy (246/287) was 4.8 months (95%CI 3.9–5.7) vs 3.7 months (95%CI 1.9–5.5) in patients who did not it (HR log rank 0.78; 95%CI 0.53 to 1.15; p = 0.186). Median OS in patients who had previous nephrectomy (246/287) was 20.9 months (95%CI 17.6–24.1) vs 13 months (95%CI 7.7–18.2) in patients who did not it (HR log rank 0.504; 95%CI 0.337 to 0.755; p = 0.001). In the multivariate model, nephrectomy showed a significant association with OS (HR log rank 0.638; 95%CI 0.416 to 0.980), whereas gland metastases were still associated with better outcome in terms of both OS (HR log rank 0.487; 95%CI 0.279 to 0.852) and PFS (HR log rank 0.646; 95%CI 0.435 to 0.958).ConclusionsIO treatment, in patients who had previously undergone nephrectomy, was associated with a better outcome in terms of OS. Further prospective trials would assess this issue in order to guide clinicians in real word practice.
