H3 K27m Mutations

Abstract Glioblastoma of the thalamus occurs predominantly in childhood and young adulthood, and cases with histone mutations are thought to have a particularly poor prognosis. We studied tumor resection rate, age, type of adjuvant therapy, and histone gene mutations on progression-free survival (PFS) and overall survival (OS) in patients who underwent aggressive removal. Eight cases of thalamic glioblastoma were included in the study. The mean age at surgery was 36.1 years (10–74 years, 3 cases under 18 years). Tumor removal was performed from the parieto-occipital lobe to the thalamus via the lateral ventricles in all cases. In all cases, more than 90% of the contrast-enhancing lesions were removed. Postoperatively, one patient had sensory disturbance of the left upper limb, and the other had incomplete paralysis of the left upper and lower limbs, but both were able to walk with a cane. In the case of the patient with postoperative complications, the tumor was located in the vicinity of the internal capsule. All patients were treated with radiation therapy and temozolomide, and bevacizumab and Novo-TTF were used in cases after approval. All patients were able to return home and return to school or work after initial treatment. The mean progression-free survival (PFS) was 0.87 years, and overall survival (OS) was 1.95 years. Five patients had histone H3-K27M mutations, and three patients had no mutations. PFS and OS were 1.02 years and 0.62 years, respectively, and 2.53 years and 1.20 years, respectively, both of which were longer in patients with mutations (PFS; p=0.16, OS; p=0.23).Aggressive removal of glioblastoma of the thalamus may improve prognosis, especially in patients with histone H3-K27M mutations. In patients with tumors extending to the vicinity of the internal capsule, total removal may cause paralysis and sensory disturbance.

A retrospective study of 81 patients with low-grade astrocytoma (LGA) comparing the efficacy of aggressive versus less aggressive surgery in eloquent and non-eloquent brain areas was conducted. Extent of surgical resection was analyzed to assess overall survival (OS) and progression- free survival (PFS). Degree of tumor resection was classified as gross total resection (GTR), subtotal resection (STR) or biopsy. GTR, STR and biopsy in patients with tumors in non-eloquent areas were performed in 31, 48 and 21% subjects, whereas in patients with tumors in eloquent areas resections were 22.5, 35 and 42.5%. Overall survival was 4.7 and 1.9 years in patients with tumors in non-eloquent brain areas submitted to GTR/STR and biopsy (p=0.013), whereas overall survival among patients with tumors in eloquent area was 4.5 and 2.1 years (p=0.33). Improved outcome for adult patients with LGA is predicted by more aggressive surgery in both eloquent and non-eloquent brain areas.

Introduction: In advanced breast cancer, local treatment is considered palliative. However, although there are some polemic opinions about the surgical treatment, some of the latest studies have emphasized that in advanced cases primary tumor resection (PTR) is related to better outcomes. This review aims to evaluate how resection of the original tumor impacts women with metastatic breast cancer, considering the most recent studies about this subject. Methods: The search was performed in MEDLINE, Scopus, PMC, Current Contents and Wiley Online Library databases; 23 articles - from 2016 to 2019 - were selected and 11 were included in this review. As inclusion criteria were considered: studies presenting outcomes about resection of the primary tumor, comparison between chemotherapy/ hormone therapy/ targeted cancer therapies and surgical intervention, studies published from 2016 to 2019 and available in English, Spanish or Portuguese. We excluded those which did not approach PTR, did not present outcomes of interest (progression-free survival comparison between PTR and systemic therapy) or only discussed systemic therapy, as well as those published before 2016. Results: It was reported in 6 studies that progression-free survival is better on those who underwent surgery. PTR was also related to longer median overall survival in women submitted to surgery, up to 16 months higher when compared to the ones who were not. Enhanced survival even pertained to surgical groups regardless of tumor size.  Conclusion: Based in the analysis, PTR in metastatic breast cancer can be related to higher overall survival.

✓ Low-grade gliomas constitute the largest group of cerebral hemispheric tumors in the pediatric population. Although complete tumor resection is generally the goal in the management of these lesions, this can prove difficult to achieve because tumor margins may blend into the surrounding brain. This raises several important questions on the long-term behavior of the residual tumor and the role of adjuvant therapy in the management of these lesions. To examine these issues, the authors reviewed their experience in 71 children with low-grade cerebral hemispheric gliomas who were treated at their institution between 1956 and 1991 and assessed the relationship between clinical, radiographic, pathological, and treatment-related factors and outcome. Only seven patients in the series died, one from perioperative complications, five from progressive disease, and one (a child with neurofibromatosis) from a second neoplasm. For the 70 patients who survived the perioperative period, overall actuarial survivals at 5, 10, and 20 years were 95%, 93%, and 85%, respectively; progression-free status was maintained in 88%, 79%, and 76%, respectively. On univariate analysis, the factor that was most strongly associated with both overall and progression-free survival was the extent of tumor resection (p = 0.013 and p = 0.015, respectively). A relationship between extent of resection and progression-free survival was present both in patients with pilocytic astrocytomas (p = 0.041) and those with nonpilocytic tumors (p = 0.037). Histopathological diagnosis was also associated with overall survival on univariate analysis; poorer results were seen in the patients with nonpilocytic astrocytoma compared to those with other low-grade gliomas, such as pilocytic astrocytoma, mixed glioma, and oligodendroglioma (p = 0.021). The use of radiotherapy was not associated with a significant improvement in overall survival (p = 0.6). All three patients who ultimately developed histologically confirmed anaplastic changes in the vicinity of the original tumor had received prior radiotherapy, 20, 46, and 137 months, respectively, before the detection of malignant progression. In addition, children who received radiotherapy had a significantly higher incidence of late cognitive and endocrine dysfunction than the nonirradiated patients (p < 0.01 and 0.05, respectively). The authors conclude that children with low-grade gliomas of the cerebral hemispheres have an excellent overall prognosis. Complete tumor resection provides the best opportunity for long-term progression-free survival. However, even with incomplete tumor excision, long-term progression-free survival is common. The findings in this study do not support the routine use of postoperative radiotherapy after an initial incomplete tumor resection: although irradiation appears to increase the likelihood of long-term progression-free survival, overall survival is not improved significantly, and long-term morbidity may be increased.

16068 Background: For optimal debulked mullerian cancer (MC), the Intraperitoneal (IP) therapy has become the effective modality of chemotherapy to obtain better prognosis. We have reported KCOG9811study: IP CDDP + Paclitaxel (PTX) intravenous (IV) 2 cycles followed by 3 cycles of usual PTX-Carboplatin (abstr.1970, ASCO2002). And we have also reported the feasibility study and satisfactory response rate of the weekly IP-PTX with IV Carboplatin therapy (IP-PIVC, abstr. 5120, ASCO2005). Objectives: We have conducted two types of IP therapy for optimal debulked MC to improve the progression free survival (PFS) and overall survival (OS). Here are the prognosis and recurrent fashion after these IP therapies. Methods: Twenty patients (pts) with optimal debulked ovarian cancer were enrolled for KCOG9811, and eleven pts with optimal debulked MC newly/recurrent diagnosed disease were enrolled for IP-PIVC. The regimen of each therapy consisted of as follows: KCOG9811:50mg/ m2 of CDDP was administered via IP port at operation, after 2 weeks (wks) of operation, PTX was administered at a dose of 175mg/ m2IV for 3hrs on day 1, CDDP was administered at 75mg/ m2IP on day 2, every 3wks for 2 cycles, followed by PTX 175mg/ m2 IV and Carboplatin AUC5 IV on day1 every 3wks for 3 cycles. The IP-PIVC therapy consisted of IP-PTX, on days 1, 8, 15 at a dose of 45 mg/m2 (3pts) and 60 mg/m2(8pts). Carboplatin was administered monthly at a dose of AUC 5 on day 1 only. 2–6 cycles were performed. Results: The mean observation time was 72.6 months (m) and 32.6m for KCOG9811 and IP-PIVC, respectively. As for the median PFS was 1308+ days and 678+ days, and the median OS was 2180+ days and 978+ days, respectively. The five years survival rate showed 59.3% on KCOG9811, and the three years survival rate showed 75.8% on IP-PIVC. As for recurrent fashion, liver metastases and proximal lymphnodes metastases, and retroperitoneal metastases were detected. Few cases recurred Intraperitoneal lesion with small ascites Conclusions: There are some differences in the recurrent fashion of IP treatment from that of IV treatment. IP treatment prevented ascitic recurrence. Further improvement of chemotherapy is necessary for liver metastasis and proximal lymphnodes. [Table: see text]

e21202 Background: Increased systemic inflammatory state and increased inflammation within tumor micro-environment (TME) have been associated with a worse prognosis and lower responsiveness to immune checkpoint inhibitors (ICI). Systemic inflammatory immune index (SII) reflects the changes in the systemic inflammatory matrix. Studies have shown the association of SII with cancer survival and treatment outcomes. We aim to study the effect of SII on treatment outcomes in non-small cell lung cancer (NSCLC) patients being treated with ICI. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs (pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab) alone or in combination with chemotherapy. SII is the product of platelets multiplied by neutrophils divided by lymphocytes. Baseline and 8-week SIIs were obtained. Radiographic response, duration of radiographic response (date of best response to radiographic progression), overall survival (OS), and progression-free survival (PFS) were evaluated. A high SII was defined as a value greater than the median SII. Cox regression univariate and multivariate analyses were performed. Logistic regression, t-test, and Chi-square tests were applied. Results: Overall, 81% patients had adenocarcinoma and 19% patients had squamous, adenosquamous or large cell carcinoma. The majority of the patients were female (56.2% vs. 43.8%). Median SII at baseline was 1335. The objective response rate (ORR) was 45.1%. The disease control rate was 75.8%. The ORR was 51% in patients receiving ICI first-line compared to 35% in those who received ICI as a second-line therapy. At baseline, there was no difference in the mean SII between responders and non-responders (2146.2 vs. 1917.5, P = 0.5); however at 8 weeks, the mean SII was significantly lower in responders compared to non-responders (1198.8 vs. 2880.2, P = 0.02). A total of 15 (10.9%) patients were found to have pseudoprogression or mixed response on follow-up imaging. Among these, 11(73.3%) patients had low SII at 8 weeks (P = 0.04). The median OS was significantly higher in patients with low SII at baseline (29.6 months vs. 10.1 months, P = 0.001 95% CI 10.6 – 22.1). Similarly, there was a significant difference in median PFS in patients with low SII (14.6 months vs. 6.7 months, P = 0.002, 95% CI 5.6 – 11.6). There was no correlation between high or low SII on the incidence of immune-related adverse events. Conclusions: SII may have significant impact on OS and PFS and could be serially monitored to assess the response to ICI. A low SII may help to differentiate pseudoprogression vs. true progression. Prospective studies are needed to validate these findings. Further, it will be interesting to see if SII could be incorporated into predictive models to determine the duration of cytotoxic therapy in selected patients.

Abstract Abstract 2917 Background: The European LeukemiaNet MDS (EUMDS) registry is designed to collect information about the demographics and disease-management of newly diagnosed low-risk and intermediate-1 risk MDS patients. From April 2008 until July 2010, 828 patients have been registered in eleven participating countries through a web-based reporting system. Objectives: This report describes the disease-management of the first 800 registered patients, including transfusion-related issues like secondary iron overload and its treatment. Results: 159 of 800 patients (20%) started MDS specific treatment within three months before registration; this percentage increased to 50% at 18 months of follow-up. Most patients received erythroid-stimulating agents (ESA), like erythropoietin (Table 1). In patients with a clinical indication for ESA, the percentage of transfusion-independency was similar to the transfusion-independent group without indication for ESA at 18 months of follow-up (Table 1). Overall, 27% of the patients received blood transfusions at registration. This percentage remained stable during follow-up, probably due to the therapeutic effect of ESA (Table 1). The number of units transfused, per 6 months, in these patients increased from 5 to 13 units at 18 months of follow-up, with a mean pre-transfusion Hb level of 7.6 g/dL. The serum ferritin levels of the transfusion-dependent patients at registration were available in 159 patients. The serum ferritin level at registration was ≥2000 μg/L in 4% of the patients who received a mean number of 10 units (SD 7). This increased to 28% of the patients who received a mean number of 20 units (SD 11) at 18 months of follow-up. The percentage of patients on iron chelation therapy increased from 1% to 9% during follow-up (Table 1). In these patients the mean serum ferritin levels remained stable: 1913 μg/L (SD 1183) at registration and 1626 μg/L (SD 1232) at 18 months of follow-up. In contrast, transfusion-dependent patients not treated with iron chelation or ESA had increasing ferritin levels, with a mean ferritin of 630 μg/L (SD 597) at registration and 1586 μg/L (SD 1017) at 18 months of follow-up. 37 patients (5%) progressed to high-risk MDS or acute myeloblastic leukemia at a median of 155 days from registration. 62 patients (8%) have died within a median of 269 days from registration, 32 deaths were MDS related. The overall survival was 93% at 18 months of follow-up, with a progression-free survival of 90%. Differences in overall survival between transfusion-independent and transfusion-dependent patients were significant: 97% versus 85%, respectively (p<0.0001; Table 2). In the multivariate analysis transfusion-dependency, ferritin levels and IPSS score predicted survival (Table 2). The IPSS score had a significant prognostic impact on overall survival and progression-free survival in contrast to the WHO classification (Data not shown). Conclusions: Despite a high transfusion load the mean serum ferritin levels remained stable during treatment with iron chelation. Transfusion-dependent patients had a worse overall survival and progression-free survival with higher ferritin levels and higher IPSS score as compared to transfusion-independent patients. This report demonstrates the importance of detailed disease-management in low- and intermediate-1 risk MDS patients.

Background. Despite surgery, radiotherapy, and chemotherapy, the prognosis of relapsed grade III gliomas remains poor. After promising results of immunotherapy in grade IV gliomas, we investigated its safety and efficacy in recurrent grade III gliomas. Methods. Thirty-nine patients received vaccines containing dendritic cells loaded with autologous tumor lysate after tumor resection. Progression-free survival (PFS) and overall survival (OS) were compared with those obtained after temozolomide (TMZ) treatment as found in the literature. Results. Median PFS and OS were 4.6 and 20.5, 3.4 and 18.8, 7.8 and 13.3 months in recurrent grade III astrocytoma, oligodendroglioma, and oligoastrocytoma, respectively. Compared with TMZ, no grade III/IV toxicity was reported and median OS tended to be higher although there was no difference in median PFS. The perceived benefit of immunotherapy was more pronounced in astrocytic tumors. Conclusions. We provide the first description of immunotherapy in recurrent grade III glioma as safe, promising, and feasible.

Objective: In view of concerns about toxicity and deliverability of induction chemotherapy and its impact on subsequent chemoradiotherapy, a retrospective review was carried out with patients treated for locally advanced head and neck cancer (LAHNC) in a single centre between 2007-2017. Patients and Interventions: Patients with LAHNC and good performance status receiving induction chemotherapy with docetaxel, cisplatin and 5-fluorouracil (TPF) followed by chemoradiotherapy to 70Gy in 35 daily fractions with platinum-based chemotherapy. Main Outcome Measures: Overall and cause-specific survival, rates of locoregional recurrence or distant metastasis, treatment-related toxicity. Results: One hundred and eight patients with LAHNC were treated with 1-4 cycles of TPF (95 receiving two cycles) followed by chemoradiotherapy. The mean delivered dose intensity was 97.6% for all TPF cycles. Median interval from the start of the final cycle of TPF to the start of radiotherapy was 24 days, with 92/103 (89%) starting radiotherapy within 28 days. Median radiation treatment time was 47 days. The mean delivered dose intensity for chemotherapy delivered concurrently with radiotherapy was 97%. There were significantly fewer dose reductions in those receiving platinum/5FU combinations than platinum only regimes (P < 0.0001). For those receiving two cycles of TPF, 90% of patients completed the whole course of treatment within 14 weeks (median overall treatment time 13.1 weeks). There were four treatment-related deaths during induction chemotherapy and none during radiotherapy. Twenty-five developed locoregional failure and 13 distant metastases (both in eight). Actuarial overall survival was 60.7% at five years, with progression-free survival of 77.9% at two years and 74.1% at five years. For oropharynx cancers, overall survival was 70.4% and progression-free survival 80.8% at five years. Conclusion: Although significant toxicity from TPF was observed, with appropriate support, it is possible to complete treatment without undue compromise of subsequent treatment.

e16541 Background: Primary cytoreduction is the cornerstone in the management of epithelial ovarian cancer (OC). However, the roles of salvage surgery and of tumor reduction are still discussed controversially. The present study was conducted to assess the impact of secondary tumor reduction surgery on progression-free survival and on overall survival. Methods: Between September 2000 and April 2006, 177 consecutive patients (pts) with a first relapse of OC underwent secondary tumor reduction surgery at our department. The achieved tumor reduction was categorized as 1/5 (20% tumor debulked), 2/5 (40%), 3/5 (60%), 4/5 (80%), or 5/5 (macroscopic tumor-free) and the maximal tumor diameter was also denoted (tumor free, < 1cm, ≥ 1cm). Results: The median age was 56 years (95% CI: 23–83), median follow-up was 10.8 months (95% CI: 1–65). In 79 pts (44.6%) complete macroscopic tumor resection was achieved (median overall survival (OAS) 60.6 months, 21.3–99.8 and median progression-free survival (PFS) 14.9 months, 11.7–18, p < 0.001). In 56 pts (31.6%) 4/5 of the tumor was removed (OAS 15.6 months, 10.3–20.8 and PFS 9 months, 7.2–10.7, p < 0.001), in 13 (7.3%) 3/5 (OAS 21.7 months, no interval and PFS 12 months, 0.0–24.5, p < 0.001) and in 7 (4%) each 2/5 tumor reduction (OAS was 14.2 months, 4.1–24.2 and PFS 11 months, 5.9–16, p < 0.001) and if 1/5 tumor reduction was achieved OAS was 11.1 months, 2–20.1 and PFS 7 months, 2.5–11.4, p < 0.001. Fifteen pts (8.5%) had a bulky unresected disease (OAS 4.7 months, 1.0–8.3 and PFS of 3.7 months, 0–7.6, p < 0.001). From these 98 (55.4%) pts without complete macroscopic tumor resection, 46 were left with <1cm tumor diameter (OAS 17.2 months, 13–21.4 and PFS 9 months, 7.4–10.6 p < 0.001) and 52 with ≥1cm tumor diameter (OAS 8.7 months, 4.2–13.2 and PFS 7 months, 5.8–8.2 p < 0.001). All in all, the median postoperative survival for pts with tumor residuals and any tumor reduction (4/5, 3/5, 2/5. and 1/5 tumor reduction) were better when compared to pts with no tumor reduction (24.8 months vs. 4.7, p < 0.001). Conclusions: Our data demonstrate a significant benefit for salvage surgery if a macroscopic complete tumor resection can be achieved. We could not see any effect of relative tumor reduction on PFS or OAS. No significant financial relationships to disclose.

Object Optimal treatment of primary and recurrent craniopharyngiomas remains controversial. Radical resection and limited resection plus radiation therapy yield similar rates of disease control and overall survival. The data are much less clear for recurrent tumors. The authors report their experience with radical resection of both primary and recurrent craniopharyngiomas in children and compare the outcomes between the 2 groups. Methods A retrospective analysis was performed in 86 children younger than 21 years of age who underwent a total of 103 operations for craniopharyngioma between 1986 and 2008; these were performed by the senior author. The goal was resection with curative intent in all patients. Two patients were lost to follow-up and were excluded from analysis. The mean age at the time of surgery was 9.6 years, and the mean follow-up was 9.0 years. Results All 57 children with primary tumors underwent gross-total resection (GTR). A GTR was achieved in significantly fewer children with recurrent tumors (18 [62%] of 29). There were 3 perioperative deaths (3%). Tumor recurred after GTR in 14 (20%) of 71 patients. Overall survival and progression-free survival were significantly better in patients with primary tumors at time of presentation to the authors' institution. There were no significant differences in the neurological, endocrinological, visual, or functional outcomes between patients with primary and those with recurrent tumors. Factors negatively affecting overall survival and progression-free survival include subtotal resection (recurrent tumors only), tumor size ≥ 5 cm, or presence of hydrocephalus or a ventriculoperitoneal shunt. Prior radiation therapy and increasing tumor size were both risk factors for incomplete resection at reoperation. Conclusions In the hands of surgeons with experience with craniopharyngiomas, the authors believe that radical resection at presentation offers the best chance of disease control and potential cure with acceptable morbidity. While GTR does not preclude recurrence and is more difficult to achieve in recurrent tumors, especially large and previously irradiated tumors, radical resection is still possible in patients with recurrent craniopharyngiomas with morbidity similar to that of primary tumors.
