Abstract Background: Anaplastic thyroid carcinoma is a rare malignant tumor of the thyroid. In this study, we summarize the survival changes of Anaplastic thyroid carcinoma in recent years. Methods: Patients with Anaplastic thyroid carcinoma were selected from The Surveillance, Epidemiology, and End Results database (1973-2015). Survival rates were calculated and survival trends were compared among different stage, different years, under surgery and under radiotherapy or not.Results: A total of 1293 patients were enrolled in the study. The 5-year overall survival (OS) for Stage IVA, B and C were 26.6%, 11.7% and 2.5%, respectively. The 5-year cancer-specific survival (CSS) for the same respective stage were 43.5%, 22.3% and 4.9%. After year 1995, the CSS was further improvement (χ2=13.608, P=0.003 for log-rank test) and there was obvious improvement in survival for patients at stage IVB and stage IVC (stage IVB: χ2=12.987, P=0.005, stage IVC: χ2=21.992, P<0.001 for log-rank test). The surgery survival benefit was only observed in Stage IVB (OS: χ2=43.887, P<0.001, CSS: χ2=27.301, P<0.001 for log-rank test) and C (OS: χ2=16.399, P<0.001, CSS: χ2=12.521, P<0.001 for log-rank test). The radiotherapy OS benefit was observed in all different stage(stage IVA: χ2=7.346, P=0.007 for log-rank test, stage IVB: χ2=37.491, P<0.001 for log-rank test，stage IVC: χ2=23.208, P<0.001 for log-rank test) and the CSS benefit was observed in Stage IVB (χ2=18.717, P<0.001 for log-rank test) and C (χ2=12.615, P<0.001 for log-rank test). The median OS of patients with stage IV A receiving surgery, radiotherapy alone and the combination of the two is 4, 5 and 33 months (95% CI: 0.411-7.589, 0.000-10.500, 16.290-49.710, respectively). For Stage IVA patients, compared with the patients received surgery alone, the survival benefit was observed in patients who received surgery and radiotherapy combined (OS: χ2=6.454, P=0.011 for log-rank test). Conclusion: The 5-year cancer-specific survival for Anaplastic thyroid carcinoma was improved in recent years since 1990s. Patients with local metastasis or distant metastasis could benefit from surgery and radiotherapy. For Stage IVA patients, surgery or radiotherapy alone did not improve the cancer-specific survival. Combination of surgery and radiotherapy should get survival benefit.

Object Intracranial hemangiopericytoma (HPC) is a rare and malignant extraaxial tumor with a high proclivity toward recurrence and metastasis. Given this lesion's rarity, little information exists on prognostic factors influencing mortality rates following treatment with surgery or radiation or both. A systematic review of the published literature was performed to ascertain predictors of death following treatment for intracranial HPC. Methods The authors identified 563 patients with intracranial HPC in the published literature, 277 of whom had information on the duration of follow-up. Statistical analysis of survival was performed using Kaplan-Meier and Cox regression analysis. Results Hemangiopericytoma was diagnosed in 246 males and 204 females, ranging in age from 1 month to 80 years. Among patients treated for HPC, overall median survival was 13 years, with 1-, 5-, 10-, and 20-year survival rates of 95%, 82%, 60%, and 23%, respectively. Gross-total resection alone (105 patients) was associated with superior survival rates overall, with a median survival of 13 years, whereas subtotal resection alone (23 patients) resulted in a median survival of 9.75 years. Subtotal resection plus adjuvant radiotherapy led to a median survival of 6 years. Gross-total resection was associated with a superior survival benefit to patients regardless of the addition or absence of radiation, and patients receiving > 50 Gy of radiation had worse survival outcomes (median survival 4 vs 18.6 years, p < 0.01, log-rank test). Patients with tumors of the posterior fossa had a median survival of 10.75 versus 15.6 years for those with non–posterior fossa tumors (p < 0.05, log-rank test). Conclusions Treatment with gross-total resection provides the greatest survival advantage and should be pursued aggressively as an initial therapy. The addition of postoperative adjuvant radiation does not seem to confer a survival benefit.

Abstract Background Previous studies have reported poor survival rates in inflammatory breast cancer (IBC) patients than non-inflammatory local advanced breast cancer (non-IBC) patients. However, until now, the survival rate of IBC and other T4 non-IBC (T4-non-IBC) patients remains unexplored. Methods Surveillance, Epidemiology, and End Results (SEER) database was searched to identify cases with confirmed non-metastatic IBC and T4-non-IBC who had received surgery, chemotherapy, and radiotherapy between 2010 and 2015. IBC was defined as per the American Joint Committee on Cancer (AJCC) 7th edition. Breast Cancer-Specific Survival (BCSS) was estimated by plotting the Kaplan-Meier curve and compared across groups by using the log-rank test. Cox model was constructed to determine the association between IBC and BCSS after adjusting for age, race, stage of disease, tumor grade and surgery type. Results Out of a total of 1986 patients, 37.1% had IBC and mean age was 56.6 ± 12.4. After a median follow-up time of 28 months, 3-year BCSS rate for IBC and T4-non-IBC patients was 81.4 and 81.9%, respectively (log-rank p = 0.398). The 3-year BCSS rate in HR−/HER2+ cohort was higher for IBC patients than T4-non-IBC patients (89.5% vs. 80.8%; log-rank p = 0.028), and in HR−/HER2- cohort it was significantly lower for IBC patients than T4-non-IBC patients (57.4% vs. 67.5%; log-rank p = 0.010). However, it was identical between IBC and T4-non-IBC patients in both HR+/HER2- (85.0% vs. 85.3%; log-rank p = 0.567) and HR+/HER2+ (93.6% vs. 91.0%, log-rank p = 0.510) cohorts. After adjusting for potential confounding variables, we observed that IBC is a significant independent predictor for survival of HR−/HER2+ cohort (hazards ratio [HR] = 0.442; 95% CI: 0.216–0.902; P = 0.025) and HR−/HER2- cohort (HR = 1.738; 95% CI: 1.192–2.534; P = 0.004). Conclusions Patients with IBC and T4-non-IBC had a similar BCSS in the era of modern systemic treatment. In IBC patients, the HR−/HER2+ subtype is associated with a better outcome, and HR−/HER2- subtype is associated with poorer outcomes as compared to the T4-non-IBC patients.

AbstractWe aimed to assess the clinicopathological features and to determine the prognostic factors of cervical adenocarcinoma (AC). Relevant data were extracted from surveillance, epidemiology and end results database from 2004 to 2015. The log-rank test and Cox proportional hazard analysis were subsequently utilized to identify independent prognostic factors. A total of 3102 patients were identified. The enrolled patients were characterized by higher proportion of early FIGO stage (stage I: 65.9%; stage II: 14.1%), low pathological grade (grade I/II: 49.1%) and tumor size ≤ 4 cm (46.8%). The 5- and 10-year cancer-specific survival rates of these patients were 74.47% and 70.00%, respectively. Meanwhile, the 5- and 10-year overall survival (OS) rates were 71.52% and 65.17%, respectively. Multivariate analysis revealed that married status, surgery as well as chemotherapy were independent favorable prognostic indicators. Additionally, aged > 45, tumor grade III/IV, tumor size > 4 cm, advanced FIGO stage and pelvic lymph node metastasis (LNM) were unfavorable prognostic factors (all P < 0.01). Stratified analysis found that patients without surgery could significantly benefit from chemotherapy and radiotherapy. In addition, chemotherapy could significantly improve the survival in stage II–IV patients and radiotherapy could only improve the survival in stage III patients (all P < 0.01). Marital status, age, grade, tumor size, FIGO stage, surgery, pelvic LNM and chemotherapy were significantly associated with the prognosis of cervical AC.

Objective. The aim of our study was to compare long-term oncological outcomes following nephron-sparing surgery (NSS) and radical nephrectomy (RN) for renal cell carcinoma (RCC) 4 to 7 cm in diameter. Material and Methods. The study included patients who underwent RN or NSS for RCC 4 to 7 cm in diameter between 1998 and 2009. The studied groups were compared with respect to the patients’ age, sex, physical status according to the American Society of Anesthesiologists Physical classification, histological type, stage, tumor size, grade, duration of the operation, and complications. Survival was established using the Kaplan-Meier method. The risk factors for survival were analyzed using a multivariate Cox regression model. Results. During the study, 351 patients underwent surgery: 317 patients (90.3%) underwent RN, and 34 (9.7%), NSS. The compared groups differed with respect to tumor size (P=0.001) and stage (P=0.006). The overall estimated 12-year survival was 53.7% after RN and 55.2% after NSS (log-rank test P=0.437). The 12-year cancer-specific survival in the RN and NSS groups was 69.6% and 80.6%, respectively (log-rank test P=0.198). Pathological stage and patients’ age were the major factors affecting both overall and cancer-specific survival. The type of surgery (NSS or RN) had no effect on survival. Conclusions. Our study showed that nephron-sparing surgery is a safe technique compared with radical nephrectomy that ensures good oncological control in the treatment of renal cell carcinoma measuring 4 to 7 cm and may be proposed as the treatment of choice for renal tumors not only up to 4 cm, but also 4 to 7 cm in size.

Abstract Background The treatment effect in survival analysis is commonly quantified as the hazard ratio, and tested statistically using the standard log-rank test. Modern anticancer immunotherapies are successful in a proportion of patients who remain alive even after a long-term follow-up. This new phenomenon induces a nonproportionality of the underlying hazards of death. Methods The properties of the net survival benefit were illustrated using the dataset from a trial evaluating ipilimumab in metastatic melanoma. The net survival benefit was then investigated through simulated datasets under typical scenarios of proportional hazards, delayed treatment effect, and cure rate. The net survival benefit test was computed according to the value of the minimal survival difference considered clinically relevant. As comparators, the standard and the weighted log-rank tests were also performed. Results In the illustrative dataset, the net survival benefit favored ipilimumab [Δ(0) = 15.8%, 95% confidence interval = 4.6% to 27.3%, P = .006]. This favorable effect was maintained when the analysis was focused on long-term survival differences (eg, >12 months, Δ(12) = 12.5% (95% confidence interval = 4.4% to 20.6%, P = .002). Under the scenarios of a delayed treatment effect and cure rate, the power of the net survival benefit test compared favorably to the standard log-rank test power and was comparable to the power of the weighted log-rank test for large values of the threshold of clinical relevance. Conclusion The net long-term survival benefit is a measure of treatment effect that is meaningful whether or not hazards are proportional. The associated statistical test is more powerful than the standard log-rank test when a delayed treatment effect is anticipated.

e22517 Background: Since the first steps of its clinical development, trabectedin was noticed to be extremely active against myxoid liposarcoma (MLS), whose pathogenesis seems to be associated to the presence of the t(12;16)(q13;p11) translocation, resulting in the expression of FUS-DDIT3 fusion genes. Therefore, the drug seems to induce a maturation of MLS lipoblasts, with transition of the residual spindle non-lipogenic cells into mature vacuolated lipoblasts. This effect could be prevented by the increase of leptin circulating levels in obese patients. For these reasons we designed this retrospective analysis in order to evaluate the BMI status (measure of total adipose content) as a predictors or efficacy of trabectedin in MLS patients. Methods: Patients were treated in cancer centers with trabectedin at the approved dose of 1.5 mg/m2, given as a 24-hour infusion every 3 weeks. This retrospective analysis was preformed on the basis of clinical charts or databases. For the purpose of this analysis only patient with a BMI > 18.5 were included and an the population divided into two categories: normal weight if BMI < 25, overweight > 25. An analysis of the correlation between BMI and objective response (OR) rate, tumor control (TC) rate (OR+stable disease lasting ≥3 months), progression-free survival (PFS) and overall survival (OS) was performed. Results: 62 adult patients with recurrent MLS were enrolled (M/F: 33/29; median age: 53 ys). All patients were doxorubicin-pretreated. The median BMI in the whole population was 22.5 (range: 1.85 – 29.8). No statistically significant differences were identified in terms of OR or TC. On the contrary, PFS (6.8 vs. 3.7 months; p< 0.026, log rank test) and OS (14.9 vs. 8.3 months; p< 0.0001, log rank test) were significantly prolonged in normal weighted patients vs over weighted patients. Six and 12-months Kaplan-Meier PFS estimates and survival rates at 12, 24 and 36 months were also better in those patients. Conclusions: these results seem confirm a role o adipose content as a predictor of resistance to trabectedin in MLS patients. Further studies are warranted to confirm this preliminary observation and understand the biological mechanisms of this relationship.

Yin-Deficiency (YD), representing a status of the human body under lack of nutrition and fluid in traditional Chinese medicine, is commonly seen in late stage of cancer patients. It is not known whether the severity of YD related symptoms/signs can predict the survival rate of cancer patients. This study evaluated the distribution of Yin-deficiency symptoms/signs (YDS) in cancer patients with YD, and investigated whether the severity of YDS can predict the survival rate of cancer patients with YD. From 5 January 2007 to 5 May 2007, we selected 43 cancer patients with diagnosis of YD from hospitalized patients and outpatients. The severity of YD was evaluated by a questionnaire. We further estimated the cumulative probabilities of the survival rates over 4 months since the start of study by the Kaplan-Meier product-limit method, and compared the differences among groups with various severities in each symptom/sign with the use of the log-rank test. The results revealed that, the 3 most common YDS were sleeplessness with annoyance, less or non-coated tongue with or without redness and dry mouth. In the survival rate analysis, only 2 parameters, rapidly small pulse (p = 0.002) and less-or non-coated tongue with paleness (p = 0.017), were found to be related to the decrease of cancer patients with YD. This suggests that, both rapidly small pulse and less-or non-coated tongue without redness may be used as predictors for the estimation of survival rate in cancer patients with YD.

Background: Rising NT-proBNP are associated with reduced survival patients with HFrEF. However, it remains to be conclusively and formally demonstrated that the temporal trend in NT-proBNP level carries prognostic significance in HFpEF. Objective: To determine whether there is an association between rising NT-proBNP levels and 6-month survival in patients with HFpEF and HFrEF. Methods: We examined a cohort of 5203 patients to 5 hospitals in a regional health care system — who had at least one admission to the hospital with diagnoses of heart failure over a 3-year period. Kaplan-Meier survival curves were constructed for patients with downtrending (>25% net decrease), stable or uptrending (>25% net increase) NT-proBNP levels in HF, HFpEF and HFrEF patients. The log-rank test was used to test for differences in 6-month survival amongst the groups. Multivariate extended Cox regression models were constructed for 6-month survival with NT-proBNP as a time-varying covariate. Age, albumin, sex, race, serum creatinine, systolic and diastolic blood pressures and Charlson comorbidity scores at baseline were used as covariates in the model. Separate analyses were done for HFpEF and HFrEF patients. Results: HFpEF and HFrEF patients with up-trending levels had significantly lower 6-month survival rates than patients with downtrending or stable NT-proBNP levels. A doubling of the NT-proBNP level in patients was significantly associated with reduced 6-month survival in patients with in both subgroups of HF, HFpEF and HFrEF (HFpEF-HR: 1.53(1.49-2.57), HFrEF HR: 1.45(1.43-1.48) after adjusting for covariates.

Abstract Background: Lung cancer is the leading cause of cancer-associated mortality worldwide, and in China. Central nervous system (CNS) metastasis is a prevalent and serious complication. The most common treatment for BM is still radiation therapy (RT). An increasing number of drugs have been shown to have intracranial activity or to sensitize tumours to radiotherapy.Methods: Our study aims to demonstrate the clinical efficacy of apatinib combined with radiotherapy vs. radiotherapy alone in the treatment of patients with advanced multiline failure for non-small-cell lung cancer with brain metastasis (BM). Eligible patients were divided into two groups: Apatinib + RT group and RT group. In the apatinib + RT group. Intracranial PFS and OS were analysed using the Kaplan-Meier method. Differences between groups were compared by the log-rank test.Results: The median intracranial PFS for the RT group and Apatinib+RT group was 5.83 months and 11.81 months (p=0.034). The median OS for the RT group and Apatinib+RT group was 9.02 months and 13.62 months (p=0.311). The Apatinib+RT group had a better intracranial PFS, but there were no significant differences between the two arms in OS. The Apatinib+RT group had significantly reduced symptoms caused by BM, mainly headache and vomiting. Most patients tolerated the side effects well. Conclusion: RT combined with apatinib could help to control intracranial metastases. The Apatinib+RT group had significantly reduced symptoms caused by BM, the safety of the two treatments was similar.
