Object Recently the relevance of Simpson resection grade as a prognostic factor for recurrence of WHO Grade I meningiomas was challenged, contradicting many previous scientific reports and traditional neurosurgical teaching. The objective of this study was to determine whether the predictive value of Simpson resection grade is outdated or remains valid with respect to meningioma recurrence and overall survival. Methods All patients at least 16 years old who underwent primary craniotomies for convexity meningiomas at Oslo University–affiliated hospitals (Rikshospitalet and Ullevål University Hospitals) in the period between January 1, 1990, and January 27, 2011, were included. Overall survival and retreatment-free survival rates were correlated with patient- and surgery-specific factors. Results Three hundred ninety-one consecutive patients were included in the study. The median patient age was 60.1 years (range 19–92 years). The female-to-male ratio was 2.1:1. The WHO grades were Grade I in 353 (90.3%), Grade II in 22 (5.6%), and Grade III in 16 (4.1%). The follow-up rate was 100%. Median follow-up time was 7.1 years (range 0.0–20.9 years) and total observation time was 3147 patient-years. The 1-, 5-, and 10-year overall survival rates were 96%, 89%, and 78%, respectively. Age, sex, WHO grade, and Simpson grade were significantly associated with overall survival. The 1-, 5-, and 10-year retreatment-free survival rates were 99%, 94%, and 90%, respectively. Simpson resection grade and WHO grade were significantly associated with retreatment-free survival. The hazard ratios for retreatment after combined Simpson resection Grades II+III and IV+V were 4.9- and 13.2-times higher than after Simpson Grade I resection, respectively. Conclusions Simpson Grade I resection should continue to be the goal for convexity meningiomas.

OBJECTIVEParasellar meningiomas tend to invade the suprasellar, cavernous sinus, and petroclival regions, encroaching on adjacent neurovascular structures. As such, they prove difficult to safely and completely resect. Stereotactic radiosurgery (SRS) has played a central role in the treatment of parasellar meningiomas. Evaluation of tumor control rates at this location using simplified single-dimension measurements may prove misleading. The authors report the influence of SRS treatment parameters and the timing and volumetric changes of benign WHO Grade I parasellar meningiomas after SRS on long-term outcome.METHODSPatients with WHO Grade I parasellar meningiomas treated with single-session SRS and a minimum of 6 months of follow-up were selected. A total of 189 patients (22.2% males, n = 42) form the cohort. The median patient age was 54 years (range 19–88 years). SRS was performed as a primary upfront treatment for 44.4% (n = 84) of patients. Most (41.8%, n = 79) patients had undergone 1 resection prior to SRS. The median tumor volume at the time of SRS was 5.6 cm3 (0.2–54.8 cm3). The median margin dose was 14 Gy (range 5–35 Gy). The volumes of the parasellar meningioma were determined on follow-up scans, computed by segmenting the meningioma on a slice-by-slice basis with numerical integration using the trapezoidal rule.RESULTSThe median follow-up was 71 months (range 6–298 months). Tumor volume control was achieved in 91.5% (n = 173). Tumor progression was documented in 8.5% (n = 16), equally divided among infield recurrences (4.2%, n = 8) and out-of-field recurrences (4.2%, n = 8). Post-SRS, new or worsening CN deficits were observed in 54 instances, of which 19 involved trigeminal nerve dysfunction and were 18 related to optic nerve dysfunction. Of these, 90.7% (n = 49) were due to tumor progression and only 9.3% (n = 5) were attributable to SRS. Overall, this translates to a 2.64% (n = 5/189) incidence of direct SRS-related complications. These patients were treated with repeat SRS (6.3%, n = 12), repeat resection (2.1%, n = 4), or both (3.2%, n = 6). For patients treated with a margin dose ≥ 16 Gy, the 2-, 4-, 6-, 8-, 10-, 12-, and 15-year actuarial progression-free survival rates are 100%, 100%, 95.7%, 95.7%, 95.7%, 95.7%, and 95.7%, respectively. Patients treated with a margin dose < 16 Gy, had 2-, 4-, 6-, 8-, 10-, 12-, and 15-year actuarial progression-free survival rates of 99.4%, 97.7%, 95.1%, 88.1%, 82.1%, 79.4%, and 79.4%, respectively. This difference was deemed statistically significant (p = 0.043). Reviewing the volumetric patient-specific measurements, the early follow-up volumetric measurements (at the 3-year follow-up) reliably predicted long-term volume changes and tumor volume control (at the 10-year follow-up) (p = 0.029).CONCLUSIONSSRS is a durable and minimally invasive treatment modality for benign parasellar meningiomas. SRS offers high rates of growth control with a low incidence of neurological deficits compared with other treatment modalities for meningiomas in this region. Volumetric regression or stability during short-term follow-up of 3 years after SRS was shown to be predictive of long-term tumor control.

Abstract Backgroud: Longer follow-up was necessary to testify the exact value of mastoscopic axillary lymph node dissection (MALND).Methods：From January 1, 2003 to December 31, 2005,1027 patients with operable breast cancer were randomly assigned to two groups: MALND and CALND. 996 eligible patients were enrolled. The end points are disease free survival and overall survival.Results：The final cohort of 996 patients was followed for an average of 184 months. The distribution of all events was fairly similar between two groups of patients. The incidence of local in-breast events did not differ in a significant manner between two cohorts. Similarly, the rate of distant metastases was not significantly different with 30.0% in MLND and 32.6% in CALND. And no significant difference was observed in other primary tumor between two groups (p=0.46). Patients who remain alive with no event comprise a total of 37.2% in MALND and 35.4% in CALND. Other primary cancers and deaths from other causes were distributed equally between two groups. The 15-year disease-free survival rates were41.1 percent for the MALND group and 39.6 percent for the CALND group (p=0.79). MALND was found to be not inferior for overall survival (P =0.54). The 15-year overall survival rates were 49.5 percentafter MALND and 51.2 percentafter CALND (p=0.86). Probability of overall survival was not significantly different between two groups.Conclusions：MALND does not increase unfavorable events, and also does not affect the long-term survival of patients. Therefore, MALND should be one of the preferred approaches for breast cancer surgery.

AbstractAim:Multiform glioblastoma (MG) represents 70% of all gliomas, with half of patients older than 65 years with median survival of 12–18 months, hypofractionation seeks to reduce the intensity and duration of treatment without impacting on survival rates. The objective was to determine the global survival and recurrence-free survival of adults over 70 years old with MG treated with hypofractionated radiotherapy and standard scheme. The review of patients older than 70 years treated with radiotherapy from 2013 to 2016 was performed.Results:Twenty-four patients were analysed, with a median follow-up of 239 days, and there is no difference in overall survival 12·3 versus 10·5 months (p = 0·55) and recurrence-free survival 8·3 versus 3·4 months (p = 0·48) between both schemes, conventional versus hypofractioanted, respectively.Conclusion:The results in this study show that hypofractionated scheme could be comparable in overall survival and recurrence-free survival to conventional fractionation, but a longer patients’ trial should be done.

3505 Background: In ACC “FOLFIRI” is one of the standard regimens and is able to obtain about 40% response rate (RR) with an overall survival (OS) of 17–18 months. Experimental studies (Sobrero, 2000) indicate that an alternating chemotherapy could delay the appearance of cell resistance and reduce the therapeutic load for patients (pts). Methods: In order to evaluate whether intermittent “FOLFIRI” (CPT-11: 180 mg/sqm d1 + l-folinic acid -FA: 100 mg/sqm in 2 hr + 5fluorouracil-5FU: 400 mg/sqm bolus + 600 mg/sqm 22 hr infusion, d 1 and 2 every 2 weeks, for 2 months on and 2 months off) (arm A) was at least as effective as continuous “FOLFIRI” (same regimen, every month) (arm B), until progression in both arms, 336 pts from 27 Centers were randomised from 7/2001 to 6/2005. The characteristics of pts were: median age 64 years (r 29–75), males 214 (63%), PS 0: 222 (66%), liver mets only 166 (49%), multiple mts including liver 80 (24%). Results: RR was 29% in arm A and 35% in arm B, with a median progression-free survival (PFS) of 8.8 and 7.3 months respectively (HR = 1.00, 95% CI: 0.74 - 1.36). At a median follow-up of 27 months, median overall survival (OS), the primary endpoint of the trial, was 16.9 months in arm A and 17.6 in arm B (HR = 1.11, 95% CI: 0.83 - 1.48). Toxicity was acceptable and similar in the 2 arms (WHO grade 3–4 toxicity: neutropenia in 12% pts, diarrhoea in 11%, nausea/vomiting in 4% and fatigue in 3%). Conclusions: Our results demonstrate that alternating “FOLFIRI” obtains the same survival as a continuous treatment, thus reducing the discomfort to pts and the economic costs. No significant financial relationships to disclose.

Abstract BACKGROUND WHO grade III meningiomas are rare, and clinical outcomes data are limited. To address this problem, we analyzed a single institution retrospective cohort of patients with WHO grade III meningiomas. METHODS Patients who underwent resection of WHO grade III meningiomas between 1983 and 2019 with available follow-up data were included. Treatment, local recurrence, and overall survival rates were obtained. Kaplan-Meier analysis, log rank tests, and Student’s t tests were used for statistical analyses. RESULTS Ninety consecutive patients met inclusion criteria. Median follow-up was 3.2 years (IQR: 1.2-7.9), median age was 58 years (IQR: 46-67). Twenty-three patients (26%) underwent resection alone, and 58 (64%) underwent resection with adjuvant radiotherapy. Fifty-one patients developed local recurrences, with median time to recurrence of 1.0 year (IQR: 0.6-2.9) and higher MIB-1 labeling index for tumors that recurred within 1 year (25% versus 17%, p=0.04). There was a median of 2 recurrences per patient (IQR: 1-3), with a median of 2 resections and 2 radiotherapy courses for initial and salvage treatments. Thirty-nine patients with recurrences died, with median overall survival of 3.7 years (IQR: 1.8-8.8). Thirty-seven patients (41%) had prior low grade meningioma diagnoses with subsequent transformation to grade III, including 6 (7%) with grade I, 16 (18%) with grade II, and 15 (17%) with unknown grade. There was a median of 1 low grade recurrence per patient (IQR: 0-3) before transformation to grade III, which occurred a median of 4.3 years (IQR: 2.4-9.9) after initial diagnosis. Prior low grade diagnosis was associated with shorter time to recurrence of WHO grade III meningioma (p=0.01), and worse overall survival (p=0.03). CONCLUSION Patients with WHO grade III meningioma have poor outcomes despite aggressive multimodal therapy, and there is an urgent, unmet need for new high grade meningioma treatments.

Aims and Background After the first adjuvant study on adult soft tissue sarcomas was concluded, the participating institutions continued to select and treat patients according to that protocol. The aim of this study was to test the protocol reproducibility when applied as a standard practice. Methods A call for retrospective data was launched in June 1999 (self-referral of consecutive unregistered patients); thereafter, a prospective follow-up was performed. The treatment regimen consisted of epirubicin (60 mg/m2 days 1 and 2), ifosfamide (3 g/m2/die for 3 days) and equimolar doses of 6-mercapto-ethansulfonate (MESNA), with 300 μg G-CSF administered subcutaneously from day +8 until recovery, every 3 weeks for a total of 5 cycles. Results From November 1996 to June 1999, 55 high-risk, adult patients were treated. The average median dose intensity was 89% of the planned program. Grade 3-4 toxicities were leukopenia (49%), thrombocytopenia (14%), transfusion requiring anemia in 7 patients (16%), and alopecia in all patients (100%). After a median follow-up of 70 months, 23 patients (41.8%) relapsed and 19 died. Median disease-free, local disease-free and overall survival rates have not yet been reached. The disease-free survival rates at 2 and 4 years were 73% and 57%, respectively; the corresponding overall survival rates were 91% and 70%, respectively. Conclusions The feasibility and reproducibility of the original protocol were confirmed, since disease-specific overall survival and disease-free survival rates at the same period of observation and with the same prolonged follow-up did not differ.

Abstract Our previous PALG study in 445 de novo AML patients has demonstrated that addition of cladribine to the standard daunorubicine-cytarabine (DA) remission induction regimen - DAC has a beneficial influence on both the CR rate after one induction cycle (p=0,0008) and on survival in patients older than 40 y (Leukemia2004,18:989–97, updated at 7 y: ASH 2006, Abstr.N#2003). The goal of this study was to evaluate the efficacy of original combination including another purine analogue fludarabine – DAF (daunorubicine 60 mg/m2/d iv, d 1–3; cytarabine (AraC) 200 mg/m2/d ci, d 1–7, and fludarabine 25 mg/m2 iv d 1–5) in untreated patients with AML, aged up to 60 y, based on head to head comparison with DAC - (DNR, AraC, Cladribine), and standard DA regimens. We evaluated earlier the DAF protocol in relapsed or refractory AML (PALG pilot study; Ann Hematol.2008, 87:361–7. Epub 2007 Dec 12); the tolerance was good, CR 44%, LFS 38%. Primary objectives of the presented trial were: complete remission rate (CR) and overall survival (OS); secondary objectives were: toxicity and leukemia-free survival (LFS). Additional analysis was planned for patients submitted to an early bone marrow allotransplantation (alloBMT) after CR. Patients achieving CR received two courses of subsequent intensive consolidation: HAM (HD AraC, mitoxantrone) HD AraC. Reduction of consolidation was accepted in patients treated with early alloBMT. In case of partial remission (PR) after the first induction course the same regimen was repeated. Patients with no remission (NR) or with PR after 2 induction courses were withdrawn from the study. Between 09.2004 and 05.2008, 673 adult untreated AML patients aged 18–60 y, median 47 y, sex: male 49,5%, female 50,5%, treated in 18 co-operating Polish Adult leukemia Group (PALG) centres were centrally randomised to either DAF (n=225), DAC (n=224) or DA (n=224) arm (1:1:1). PML/RAR alfa positive - FAB M3 cases were excluded. The study groups were well balanced in respect of age, sex, FAB subtype, and WBC. After a single induction course the CR rate for patients receiving DAC equalling 63% was significantly higher if compared with DA - 51% (p=0,01), whereas no significant differences were noted between DAC vs. DAF - 55% and DAF vs. DA subgroups. Also the entire CR rate of 68% in the DAC arm was higher in comparison with DA one - 57% (p=0,02). No significant differences were found between DAC vs. DAF - 60%, and DAF vs. DA. At median time of 24 months (longest observation time 3,5y) the OS rate equalled 51% for the DAC treated subgroup and was higher in comparison to the standard DA arm - 39% and the DAF arm - 36% (p=0,03). The leukemia free survival rates (LFS) in DAC, DA and DAF treated cohorts equalled 51%, 32% and 41% respectively (p=NS). The early death rates of 8–10%. were similar in the studied treatment subgroups. All patients developed WHO grade IV thrombocytopenia and agranulocytosis. The frequency and severity of infections, mucositis, vomiting, diarrhoea, alopecia, polyneuropathy as well as of cardiac, liver or kidney dysfunctions were comparable in particular arms. In conclusion, this randomised study proves that the addition of cladribine to the standard DA induction regimen (DAC) improves CR rate and the overall survival in adults with AML aged up to 60 y, without additional toxicity. This beneficial effect was not observed in patients treated using the DAF protocol with fludarabine added to the standard “DA 3+7” schedule

Abstract Background Acute lymphoblastic leukemia (ALL) remains the most common pediatric malignancy in the world. Overall survival rates have increased from 30% in the 1960s to 90% in past 10 years. Enabling this dramatic improvement are the multi-agent chemotherapeutic regimens in which asparaginase is cornerstone. Unfortunately, hypersensitivity to asparaginase has been a commonly-reported adverse event, associated with inferior outcomes in ALL. Methods Between January 1, 2005 and December 31, 2012, 97 patients were enrolled in the study. Selection criteria included those were diagnosed with ALL and given the ALL-BFM-2000 protocol at Dr. Behcet Uz Children's Hospital. Data regarding age at diagnosis, sex, follow-up duration, hypersensitivity of L- asparaginase, status of relapse and outcome were gathered from the patients’ files. The event-free survival (EFS) and the overall survival (OS) of the patients who developed and did not develop hypersensitivity to L- asparaginase were compared. Peg-asparaginase was given to patients who developed L- asparaginase hypersensitivity, and erwinia asparaginase was given if the patients developed peg-asparaginase. The asparaginase activity could not be measured. Kaplan mayer test was used to calculate the EFS and the OS. Results A total of 97 patients were evaluated. Thirty-two were standard risk, 49 were moderate risk, and 15 were high risk. 61 patients were male, and 36 were female. The median age (range) at diagnosis was 5 (1-15) years. Median (range) follow-up duration was 5.1 (0.08-7.3) years. Of the 97 patients, 28 (29.2%) developed L-asparaginase hypersensitivity. The event-free survival was 84.5 ± 4.6%, and 62.6 ± 9.4% for patients who developed and did not develop hypersensitivity, respectively (p=0.01). The overall survival rates were 89.2 ± 3.9 % and 74.6 ± 8.3% for patients who developed and did not develop hypersensitivity, respectively (p=0,07). Figure 1. Event-free survival. The five years EFS±SE for the patients who developed and did not develop native L- asparaginasehypersensitivity were 84.5 ± 4.6% and 62.6 ± 9.4%, respectively (p=0.01). Figure 1. Event-free survival. The five years EFS±SE for the patients who developed and did not develop native L- asparaginasehypersensitivity were 84.5 ± 4.6% and 62.6 ± 9.4%, respectively (p=0.01). Conclusions This study demonstrated that EFS was lower in patients with L-asparaginase hypersensitivity than those without hypersensitivity, although there were no differences in terms of OS. All of the patients with hypersensitivity received a sufficient dose of peg-asparaginase or erwinia asparaginase according to the ALL-BFM-2000 protocol. The lower EFS for patients who were switched to peg-asparaginase because of L- asparaginase may be explained by silent inactivation of peg-asparaginase. If the activity of asparaginase could not be measured, it could be preferable to switch to erwinia asparaginase. Disclosures No relevant conflicts of interest to declare.

Purpose To report on the long-term results of a randomized trial comparing a standard dose (400 mg/d) versus a higher dose (800 mg/d) of imatinib in patients with metastatic or locally advanced GI stromal tumors (GISTs). Patients and Methods Eligible patients with advanced CD117-positive GIST from 56 institutions in 13 countries were randomly assigned to receive either imatinib 400 mg or 800 mg daily. Patients on the 400-mg arm were allowed to cross over to 800 mg upon progression. Results Between February 2001 and February 2002, 946 patients were accrued. Median age was 60 years (range, 18 to 91 years). Median follow-up time was 10.9 years. Median progression-free survival times were 1.7 and 2.0 years in the 400- and 800-mg arms, respectively (hazard ratio, 0.91; P = .18), and median overall survival time was 3.9 years in both treatment arms. The estimated 10-year progression-free survival rates were 9.5% and 9.2% for the 400- and 800-mg arms, respectively, and the estimated 10-year overall survival rates were 19.4% and 21.5%, respectively. At multivariable analysis, age (< 60 years), performance status (0 v ≥ 1), size of the largest lesion (smaller), and KIT mutation (exon 11) were significant prognostic factors for the probability of surviving beyond 10 years. Conclusion This trial was carried out on a worldwide intergroup basis, at the beginning of the learning curve of the use of imatinib, in a large population of patients with advanced GIST. With a long follow-up, 6% of patients are long-term progression free and 13% are survivors. Among clinical prognostic factors, only performance status, KIT mutation, and size of largest lesion predicted long-term outcome, likely pointing to a lower burden of disease. Genomic and/or immune profiling could help understand long-term survivorship. Addressing secondary resistance remains a therapeutic challenge.

CA 15–3 has been most widely used as a serum tumor marker in follow-up and detection of breast cancer recurrence. In this study we have specifically focused upon the prognostic implications and utility of preoperative CA 15–3 levels. We have identified on our database 414 patients with breast cancer in whom serial levels of the serum tumor marker CA 15–3 had been determined at diagnosis and follow-up. We have analyzed the follow-up and clinical outcomes in these patients and from this data we have assessed the potential of CA 15–3 as a predictor of five-year overall and disease-free survival. Our results show that an initially elevated CA 15–3 level is associated with a very poor prognosis in both early and late stage disease. Elevated pre-biopsy CA 15–3 levels are associated with 14% five-year disease-free survival rates and 17% overall survival rates at five years. In contrast, normal CA 15–3 levels are associated with 47% five-year disease-free survival rates and 54% overall survival rates at five years (p<0.01). Comparison of five-year survival rates between patients with elevated and normal CA 15–3 levels in early breast cancer (stage I and II) also showed significant differences, with survival being 41% and 75%, respectively (p<0.01).
