High Grade Osteosarcoma

Recent evidence implicates cell surface proteins of the tetraspanin superfamily in the process of metastasis whereas the downregulation of KAI-1, a member of the tetraspanin family, is associated with an aggressive clinical phenotype in several types of human cancers. To determine if expression of KAI-1-1 is associated with any known prognostic marker or clinical outcome in high-grade osteosarcoma, we examined 91 nondecalcified archival samples from 47 patients for the expression of KAI-1. Archival, paraffin-embedded, and decalcified pathologic samples were examined by immunohistochemistry and results were correlated to clinical outcomes and known prognostic markers. There were 46 samples from diagnostic biopsies (1 diagnostic sample was not available), 32 tumor resection samples, and 13 metastasis samples. Thirty-three percent (n = 30) of the samples expressed KAI-1 (16 biopsies, 9 resections, and 5 metastasis). KAI-1 expression was not significantly related to known prognostic markers or to either tumor necrosis after neoadjuvant therapy or the incidence of metastasis at diagnosis. KAI-1 expression was not significantly different between paired diagnostic tumor samples and either resection or metastasis tumor samples. Twenty-five patients remain alive at a median follow-up of 95 months. The overall and progression-free survival percentages at 5 years were 62% and 47% for KAI-1-positive patients and 49% and 38% for KAI-1-negative patients, respectively. This difference was not statistically significant. We conclude that KAI-1 is expressed in a proportion of high-grade osteosarcoma but is not of clinical significance and cannot be used to stratify treatment groups for these patients.

Univariate Analyses

Factors which might influence outcome in patients with meningioma are not well-understood. Previous studies have examined associations of laboratory blood values including hemoglobin levels with patient outcomes in cancer. We hypothesized those changes in CBC before tumor resection can be used as one of the prognostic factors for tumor recurrence/progression in meningioma. To address this, we gathered the clinical and pre-operative CBC results for final analysis from 226 patients (64 males and 162 females) who underwent craniotomy for primary meningioma (grades: 157 WHO GI, 59 GII, 10 GIII) at our institution between 2001 and 2015.Individual parameters were analyzed for correlation with progression-free survival. The median recurrence free survival (RFS) was not reached and follow-up ranged 0.3-14 years. Fifty-six patients (25%) had anemia and 30% of the patients showed leukocytosis using standard cut-offs. On univariate analyses, low hemoglobin (Hb) level, as well as high leukocytes (Lkc), neutrophil (Neutro) and monocyte counts correlated with worse RFS. As expected, tumor grade was correlated with RFS. Low Hb level, high Lkc and Neutro counts were all significantly associated with RFS after adjusting for grade. Strikingly, 32% of patients with pre-operative anemia experienced a recurrence at 5 years, compared with only 11% of non-anemic patients. Conclusion: In this exploratory study, we find that pre-operative CBC data, which is readily available, may contain prognostic information relevant to subsequent risk of recurrence or progression in meningioma. While the biological mechanism for these associations is not clear, they represent hypotheses for further investigation.

High Grade Osteosarcoma

Osteosarcoma of the foot is a very rare presentation of a rare tumor entity. In a retrospective analysis, we investigated tumor- and treatment-related variables and outcome of patients registered in the Cooperative Osteosarcoma Study Group (COSS) database between January 1980 and April 2016 who suffered from primary high-grade osteosarcoma of the foot. Among the 23 eligible patients, median age was 32 years (range: 6–58 years), 10 were female, and 13 were male. The tarsus was the most commonly affected site (n=16). Three patients had primary metastases. All patients were operated: 5 underwent primary surgery and 18 received surgery following preoperative chemotherapy. In 21 of the 23 patients, complete surgical remission was achieved. In 4 of 17 patients, a poor response to neoadjuvant chemotherapy was observed in the resected primary tumors. Median follow-up was 4.2 years (range: 0.4–18.5). At the last follow-up, 15 of the 23 patients were alive and 8 had died. Five-year overall and event-free survival estimates were 64% (standard error (SE) 12%) and 54% (SE 13%), which is similar to that observed for osteosarcoma in general. Event-free and overall survival correlated with primary metastatic status and completeness of surgery. Our findings show that high-grade osteosarcoma in the foot has a similar outcome as osteosarcoma of other sites.

10515 Background: After the introduction of pre-operative chemotherapy in the early 1980s, treatment of osteosarcoma had not advantages from new drugs/modalities. Aim of this work is to analyze improvements in overall survival for patients treated over 21 years (1982–2002), with a 5-year minimum follow-up, in the largest series from a single institute ever reported, including all high grade osteosarcomas, despite histology varieties, age, site, and stage. Data are also analyzed in subgroups to define patients who benefited most. Methods: All diagnoses of high grade osteosarcoma were included. Of the 1,656 consecutive cases observed, 198 patients were excluded (41 consultation only, 129 low-grade varieties and 28 lost to follow-up). Within 1,456 included patients, 1,032 had characteristics to be enrolled in conventional clinical trials (classic histology, age < 41, localized and extremity disease). Results: Considering all patients, with a median follow-up of 12 years (5–25 yrs), 754 (51.7%) are alive, 613 continuously disease-free. Survival at 5, 10, and 15 years is 57%, 52%, and 51% respectively. Patients candidates for clinical trials have a survival rate of 68%, 64%, and 61% respectively. Survival for the other patients is 30%, 25%, and 24% respectively. Jointpoint Statistical Analysis at real 5-year follow-up shows a yearly statistically significant improvement in survival of 1.31% (95% CI 0.5–2.1), from 51% for patients treated in 1982 to 68% for those treated in 2002. Within the subgroups, survival statistically improved in patients candidates to protocols, those who relapsed, or presented with metastatic disease at diagnosis, or had axial tumors. Surgery was also analyzed, with a statistical significant increase in the percentage of limb salvage procedures without an increased rate of local recurrences. Conclusions: Despite the lack of new drugs for osteosarcoma, survival has statistically improved, especially for those patients with the worst outcome. Aggressive treatments are therefore recommended for all patients including those with poor prognosis. No significant financial relationships to disclose.

137 Background: Trifluridine/tipiracil (T) and regorafenib (R) are indicated for patients with refractory mCRC. Currently, no biomarkers are used to select which patient will benefit from which treatment. Methods: We retrospectively evaluated 212 patients who received T and/or R. Different factors associated with progression-free survival (PFS) and overall survival (OS) were analyzed. Results: T received 132, R 52, both drugs 28 patients. Median age was 64 (range 28-83), male 64%, PS 0 37%, median line of treatment 3, characteristic was similar between treatment groups. Median follow-up was 16.5 months. Median OS for T was 10.2, for R 6.9 months, P = 0.03. Factors significantly associated with OS were: ≥ 24 months from diagnosis of mCRC (0.49, P < 0.001), PS 0 (HR 1.54, P = 0.007), baseline WBC < 8 × 109/L (HR 0.47, P < 0.001), normal baseline CRP (HR 0.47, P < 0.001), ≥ 3 months from last therapy (fluoropyrimidine for T, anti-VEGF for R) (HR 0.66, P = 0.006). We developed a scoring system TASREG from these factors, 1 point for each factor, the overall score was the sum of these points and patients were divided into 3 groups: high risk group with 0 to 1 point, intermediate with 2 to 3, favorable with 4 or more points. OS for all patients according to risk group was 4.6 for high risk, 7.9 intermediate, 11.8 months favorable risk (P < 0.001). Score was also significant for T and R group evaluated separately. Score was also significant for PFS. Factors associated with OS specific for T were neutropenia G≥2 (HR 0.34, P < 0.001); for R normal baseline LDH (HR 0,40. P < 0.001), no liver metastases (HR 0.45, P = 0.002), non-synchronous disease (HR 0,40, P < 0.001). Conclusions: We could find factors associated with better outcomes for both treatment groups and factors specific for T or R. TASREG is simple prognostic tool for patients with refractory mCRC.

Abstract BACKGROUND: Magnetic resonance-guided laser-interstitial thermotherapy (MR-LITT) is a minimally invasive technique that shows promise in neuro-oncology because of its superiority in delivering precise minimally invasive thermal energy with minimal collateral damage. OBJECTIVE: In this analysis, we investigate initial data on the use of MR-LITT in the treatment of newly diagnosed high-grade gliomas. METHODS: With the use of the PubMed, OVID, and Google-scholar database systems, a comprehensive search of the English literature was performed. Eighty-five articles were identified plus 1 that is pending publication. Four articles were accounted for in this review, including 25 patients with newly diagnosed high-grade gliomas who underwent MR-LITT treatment. We evaluated safety, progression-free survival, and overall survival. RESULTS: Twenty-five patients with a mean age of 53.8 years underwent LITT treatments. On average, 82.9% of the pretreatment lesion volume was ablated. The average tumor volume treated was 16.5 cm3. The mean follow-up time was 7.6 months. Median overall survival was found to be 14.2 months (range 0.1-23 months). The median progression-free survival was 5.1 months (range 2.4-23 months); however, these data are limited by the relatively short follow-up of the patients reviewed and small sample size of only 25 patients. There was 1 (3.4%) major perioperative complication, which was a central nervous system infection. CONCLUSION: MR-LITT is a promising technology for the treatment of small, yet difficult-to-treat newly diagnosed high-grade gliomas. This study demonstrates that MR-LITT is safe, and future randomized studies are needed to evaluate its role as a treatment adjunct for newly diagnosed high-grade gliomas.

Abstract Background The aim of the study was to analyze the overall survival (OS) and progression free survival (PFS) of patients with high grade and advanced stage epithelial ovarian cancer (EOC) with at least 60 months of follow-up treated in a single gynecologic oncology institute. We compared primary debulking surgery (PDS) versus neoadjuvant chemotherapy plus interval debulking surgery (NACT + IDS) stratifying data based on residual disease with the intent to identify the rationale for therapeutic option decision and the role of laparoscopic evaluation of resectability for that intention. Patients and methods This is observational retrospective study on consecutive patients with diagnosis of high grade and International Federation of Gynecology and Obstetrics (FIGO) stage III/IV EOC referred to our center between January 2008 and May 2012. We selected only patients with a follow-up of at least 60 months. Primary endpoint was to compare PDS versus NACT + IDS in term of progression free survival (PFS) and overall survival (OS). Secondary endpoints were PFS and OS stratifying data according to residual disease after surgery in patients receiving PDS versus NACT + IDS. Finally, through Cox hazards models, we tested the prognostic value of different variables (patient age at diagnosis, residual disease after debulking, American Society of Anesthesiologists (ASA) stage, number of adjuvant-chemotherapy cycles) for predicting OS. Results A total number of 157 patients were included in data analysis. Comparing PDS arm (108 patients) and NACT + IDS arm (49 patients) we found no significant differences in term of OS (41.3 versus 34.5 months, respectively) and PFS (17.3 versus 18.3 months, respectively). According to residual disease we found no significant differences in term of OS between NACT + IDS patients with residual disease = 0 and PDS patients with residual disease = 0 or residual disease = 1, as well as no significant differences in PFS were found comparing NACT + IDS patients with residual disease = 0 and PDS patients with residual disease = 0; contrarily, median PFS resulted significantly lower in PDS patients receiving optimal debulking (residual disease = 1) in comparison to NACT + IDS patients receiving complete debulking (residual disease = 0). PDS arm was affected by a significant higher rate of severe post-operative complications (grade 3 and 4). Diagnostic laparoscopy before surgery was significantly associated with complete debulking. Conclusions We confirm previous findings concerning the non-superiority of NACT + IDS compared to PDS for the treatment of EOC, even if NACT + IDS treatment was associated with significant lower rate of post-operative complications. On the other hand, selecting patients for NACT + IDS, based on laparoscopic evaluation of resectabilty prolongs the PFS and does not worse the OS compared to the patients not completely debulked with PDS.

Introduction: Many patients with non-muscle invasive bladder cancer (NMIBC) will develop recurrences of their tumour after their first resection. Flexible cystoscopy under local anaesthesia with Holmium-YAG laser ablation of tumour (FHoLAT) is safe, well tolerated procedure with significant cost savings when compared to cystoscopy under general or regional anaesthesia. We retrospectively analysed the outcomes of a large series of patients undergoing FHoLAT at our institution between April 2006 and September 2013. Patients and methods: Patients were offered FHoLAT if the tumour recurrence was small and/or they were deemed unfit for regional or general anaesthesia. Patient data was extracted from medical records. The primary outcomes were overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS) and recurrence-free survival (RFS). Results: 232 patients with a total 522 FHoLAT procedures were included. The median follow-up was 74.8 (43.5–101) months; 18% were discharged after a recurrence free follow-up duration; 52.2% had one FHoLAT, 19.8% had two FHoLATs, 11.2% had three FHoLATs and 16.8% had four or more FHoLAT. At initial diagnosis 24.1% of patients had G1pTa, 47% G2pTa, 9.9% G3pTa and T1 in 18.9%. 4.3% had concurrent carcinoma in situ. At 10 years, OS was 47.4%, CSS was 94.1%, PFS was 82.1%, RFS was 15.8%. Conclusions: FHoLAT for bladder tumour recurrences has an acceptable CSS and PFS for patients with small low-grade tumours or patients with high-grade or T1 tumours who are unfit for regional or general anaesthesia. The role of FHoLAT in unfit patients seems clear, but further prospective trials are needed to define its role in other patient groups, particularly high-grade NMIBC. Level of evidence: 3b-4

e20574 Background: From the early 2000s, many advances in non-small cell lung cancer (NSCLC) have been made with the emergence of targeted therapies. However, because of safety concerns and a lower prevalence of relevant therapeutic targets, patients with squamous NSCLC have been excluded from many of these breakthroughs. Endostar is a novel inhibitor of tumor angiogenesis that acts specifically on neovascular endothelial cells. This study is to explore the clinical efficacy and safety of endostar in advanced squamous NSCLC patients. Methods: We performed a retrospective analysis of 259 newly diagnosed advanced squamous NSCLC patients who had received platinum-based doublet chemotherapy (PBDC) between September 2009 and March 2016. Of these patients, 116 received Endostar combined with PBDC, and 143 received PBDC only. Clinical tumor responses, progression-free survival (PFS), overall survival (OS), and toxicity profiles were recorded and analyzed. Results: After a median follow-up of 13.5 months, a improvement in PFS was observed in the Endostar group, the median PFS was7.7 months compared with 5.4 months in the control group (HR, 0.745; P= 0.034). The median OS was 19.0 months in the Endostar group versus 14.3 months in the control group, but the difference was not significant (HR, 0.780; P= 0.094). Multivariate analysis demonstrated that in patients with advanced squamous NSCLC, anti-angiogenesis therapy with Endostar, radiotherapy of primary tumor and Ⅲb stage were significant and independent predictors of improved PFS ( P< 0.05). For both arms, hematologic and gastrointestinal toxicities were the most common adverse events. Patients treated with Endostar had slightly higher rates of cardiac disorder and thromboembolic event, as compared with the control patients, but there were no statistically significant differences in toxicities overall between the 2 treatment groups. Conclusions: The current study indicates that Endostar as an anti-angiogenesis therapy combined with PBDC is able to provide further survival benefits with satisfactory toxicity in previously untreated squamous NSCLC patients, which merits further evaluation in randomized trials.

e22533 Background: STS are rare malignant tumors and relatively resistant against chemotherapy. We have previously reported 3-year follow-up on the efficacy results of perioperative chemotherapy with DXR and IFM for STS in the extremities (JCOG0304) in ASCO 2011 (abstract ID:#10078). In the present report, we analyzed 10-year follow-up results of JCOG0304. Methods: Patients with operable, FNCLCC grade 2/3 STS (T2bN0M0, AJCC 6th edition) in the extremities were treated with 3 courses of preoperative and 2 courses of postoperative chemotherapy consisted of DXR 60 mg/m2plus IFM 10 g/m2in 3-week interval. Primary endpoint was progression-free survival (PFS). Prognostic factors were evaluated by log-rank test. Results: A total of 72 patients were enrolled between March 2004 and September 2008, and 70 patients were eligible. Median follow-up period was 10.0 years for all eligible cases. The local recurrence and distant metastasis were observed in 5 and 19 patients, respectively. Ten-year progression-free survival (PFS) was 65.7% (95% CI, 53.4%-75.5%) with no PFS event within last 5-year of follow-up. Ten-year overall survival (OS) was 78.1% (95% CI, 66.3%-86.2%). Subgroup analysis demonstrated no significant difference in PFS and OS regarding age, sex, histological grade, and histology. Secondary malignancy occurred in 6 patients. Conclusions: Only a few long-term results of clinical trials of perioperative chemotherapy for STS have been reported. Our results demonstrated that the 10-year outcome of JCOG0304 for the patients with operable, high-grade STS in the extremities was stable and remained favorable. Clinical trial information: C000000096.
