<b><i>Introduction:</i></b> Gliomatosis cerebri (GC) is defined by diffuse, widespread glial tumor growth affecting three or more cerebral lobes. Previous studies in gliomas found no distinct histological or molecular GC subtype, yet the presence of GC is associated with worse median overall survival (OS). Here, we explored whether differing therapeutic strategies in first-line treatment could account for this. <b><i>Methods:</i></b> From our University Cancer Center database, 47 patients with histological diagnosis of WHO grade II or III glioma and GC imaging pattern were identified. GC criteria were confirmed by independent review. Patients with WHO grade II or III glioma with non-GC pattern served as control cohort (<i>n</i> = 343). <b><i>Results:</i></b> Within the GC patient cohort, lower WHO grade, mutated isocitrate dehydrogenase 1 (IDH1) status, and absence of contrast enhancement were associated with better OS. Compared to the control cohort, patients with GC had significantly shorter OS independent of histological diagnosis or IDH1 mutation status. Patients with GC preferentially received chemotherapy alone (62 vs. 18%), and less frequently radiochemotherapy (21 vs. 27%). OS was significantly shorter in the GC cohort compared to the non-GC cohort both for chemotherapy (3.9 vs. 7.6 years, <i>p</i> = 0.0085) and for combined radiochemotherapy (1.1 vs. 8.4 years, <i>p</i> &#x3c; 0.0001). However, when only patients who received biopsy plus chemotherapy were analyzed, the differences lost statistical significance (3.5 vs. 6.6 years, <i>p</i> = 0.196). <b><i>Conclusion:</i></b> We found major differences in the selection of first-line therapies of GC versus non-GC patients. Our results suggest that these differences may partly account for the worse prognosis of GC patients.

Abstract BACKGROUND The term gliomatosis cerebri (GC) refers to glial brain tumors with widespread tumor expansion affecting three or more cerebral lobes. Formerly considered a distinct tumor entity, recent studies found no difference in the mutational profile of glial tumors with GC growth pattern compared to non-GC gliomas. Thus, in the new WHO classification of brain tumors, GC is no longer included as a separate diagnosis. While the presence of gliomas with GC growth pattern is associated with worse overall survival (OS), the underlying factors remain to be identified. Here, we asked whether differing therapeutic strategies in first line treatment could account for the worse outcome of patients with GC growth pattern and grade II and III histology. MATERIAL AND METHODS From the patient data bank of the University Cancer Center (UCT) Frankfurt, 47 patients with histological diagnosis of WHO grade II or III glioma, and with record of GC imaging pattern were identified. GC tumor expansion was confirmed by review of MRI scans prior to treatment initiation. Patients with WHO grade II or III glioma without GC growth pattern served as control cohort (n=379). IDH mutational status was available for 75% of GC tumors (IDH R132H mutated 32%; non-mutated 43%) and 69% of non-GC tumors (IDH R132H mutated 57%; non-mutated 12%). RESULTS Within the GC patient cohort, patients with tumors without contrast enhancement, lower WHO grade and mutated IDH status showed better OS. Compared to the control cohort, patients with GC had significantly shorter OS. This was independent of histological diagnosis or IDH mutation status. Patients with GC more frequently underwent radiochemotherapy (17% vs. 9% in the non-GC cohort), and drastically more often received chemotherapy alone (51% vs. 5%). We then analyzed OS in GC and non-GC patients that had received the same first line treatments. For radiochemotherapy in GC versus non-GC patients, OS was 1.1 years vs. 12.7 years (p =0.0075, log-rank test). For upfront chemotherapy alone, OS was significantly shorter in the GC cohort than in the non-GC cohort (3,6 years vs. undefined, p =0.0016, log-rank test). CONCLUSION Differences in first-line treatment cannot account for the worse prognosis of patients with GC imaging pattern. Further studies are needed to pinpoint biological or clinical factors that might influence responsiveness to therapy and prognosis of GC tumors.

Abstract Introduction Results of randomized studies showed benefit of maintenance therapy with monoclonal anti-CD20 antibody (rituximab) in terms of time to progression (PFS) and overall survival (OS) in follicular lymphoma (FL). General recommendation, based on large clinical trial, is to give 2 years of rituximab maintenance á 375mg/m2every 2 months (12 doses) in first line setting. On the other hand, there are various rituximab maintenance schedules; however, the clear comparison of clinical efficacy is missing. Our retrospective analysis compared two different schedule of rituximab maintenance in first-line treatment of FL used in university centers participating on CLG registry. Methods Data were recruited from 1702 FL patients registered in the prospectively maintained multicentric database (Czech Lymphoma Group; CLG). For the analysis, patients with stage II-IV of new diagnosed FL (grade 1-3a) responding (complete or partial remission) to 6-8 cycles first-line RCHOP (rituximab, cyclophosphamide, doxorubicine, vincristine and prednisone) followed with rituximab maintenance (RM) were included. Completed planned maintenance was inclusion criterion. Patients with previous watch and wait or additional first line therapy (radiotherapy, other chemotherapy, transplant therapy) were excluded. Results Totally, 168 evaluable FL patients with median age 57ys (range 28-82) including 70 (41.7%) men treated with RCHOP + RM were found in CLG database. 52/168 patients received totaly 8 doses of rituximab maintenance every 3 months for 2 years (RM8 arm), whereas 47/168 patients were treated with totaly 12 doses (RM12 arm) of rituximab maintenance every 2 months for 2 years. All patients in both subgroups completed planned RM therapy. There was no difference in distribution of age, gender, FLIPI, grade, B-symptoms, bone marrow involvement, performance status, LDH and beta2microglobuline level between both arms. Induction treatment in terms of administered cycles CHOP (6xCHOP in 41/52 and 35/45 pts., for RM8 and RM12 arm) and rituximab doses (8xR in 48/52 and 41/45 pts., for RM8 and RM12 arm) was similar between arms (ns). There were 4/52 (7.7%) and 5/47 (10.6%) relapses in subgroups RM8 and RM12, with no statistical significance. Median PFS was 3.8 (2.1-5.8) years vs. 3.9 (2.4-7.8) years in RM8 and RM12 arms (not significant), and median OS 3.91 (2.2-6.94) years vs. 3.1 (2.48-8.6) years also with no statistical significance. Conclusion Our results show, that rituximab maintenance given every 2 or every 3 months for two years in first line treatment brings similar benefit to the FL patients in terms of remission duration and overall survival. Despite the fact, that presented data are retrospective observation, this is the first report comparing two different rituximab maintenance regimens in FL. Further prospective study and longer follow up are needed to confirm our preliminary data.

Abstract Background Benefit of carboplatin and dose-dense weekly paclitaxel (ddCT) in first line treatment of ovarian cancer patients has been different in Western and Asian studies. In the present study we compare progression-free survival (PFS) of ddCT to three-weekly carboplatin and paclitaxel (CT) in first-line treatment of ovarian carcinoma in a single institution in a Western population. Materials and methods We conducted a retrospective review of medical records from patients with ovarian carcinoma treated in a tertiary cancer center from 2007 to 2018. All patients treated with ddCT or CT in the first-line setting were included. Patients who received first-line bevacizumab were not included. PFS and overall survival (OS) were compared in a propensity score-matched cohort to address selection bias. Patients were matched according to age, ECOG performance status, CA 125, FIGO stage, residual disease, and histological subtype, in a 1:2 ratio. Results Five hundred eighty-eight patients were eligible for propensity score matching, the final cohort consisted of 69 patients treated with ddCT and 138 CT group. Baseline characteristics were well-balanced. After a median follow-up of 65.1 months, median PFS was 29.3 vs 20.0 months, favouring ddCT treatment (p = 0.035). In the multivariate cox regression ddCT showed a 18% lower risk of progression (HR 0.82, 95% CI 0.68–0.99, p = 0.04). Overall survival data is immature, but suggested better outcomes for ddCT (not reached versus 78.8 months; p = 0.07). Conclusion Our retrospective study has shown superior PFS of ddCT over CT regimen in first-line treatment of ovarian carcinoma in a Western population not treated with bevacizumab.

Purpose The purpose of this study was to determine the outcome of children with nephroblastoma and pulmonary metastases (PM) treated according to International Society of Pediatric Oncology (SIOP) 93-01 recommendations using pulmonary radiotherapy (RT) in selected patients. Patients and Methods Patients (6 months to 18 years) were treated with preoperative chemotherapy consisting of 6 weeks of vincristine, dactinomycin, and epirubicin or doxorubicin. If pulmonary complete remission (CR) was not obtained, metastasectomy was considered. Patients in CR received three-drug postoperative chemotherapy, whereas patients not in CR were switched to a high-risk (HR) regimen with an assessment at week 11. If CR was not obtained, pulmonary RT was mandatory. Results Two hundred thirty-four of 1,770 patients had PM. Patients with PM were older (P < .001) and had larger tumor volumes compared with nonmetastatic patients (P < .001). Eighty-four percent of patients were in CR postoperatively, with 17% requiring metastasectomy. Thirty-five patients (16%) had multiple inoperable PM and required the HR protocol. Only 14% of patients received pulmonary RT during first-line treatment. For patients with PM, 5-year event-free survival rate was 73% (95% CI, 68% to 79%), and 5-year overall survival (OS) rate was 82% (95% CI, 77% to 88%). Five-year OS was similar for patients with local stage I and II disease (92% and 90%, respectively) but lower for patients with local stage III disease (68%; P < .001). Patients in CR after chemotherapy only and patients in CR after chemotherapy and metastasectomy had a better outcome than patients with multiple unresectable PM (5-year OS, 88%, 92%, and 48%, respectively; P < .001). Conclusion Following the SIOP protocol, pulmonary RT can be omitted for a majority of patients with PM and results in a relatively good outcome.

Hepatectomy is still as the first-line treatment for the early stage HCC, but the complication rate is higher than p-RFA and the overall survival rate is comparable in these two treatments. Therefore, the patients with small single nodular HCCs could get more benefit from p-RFA, and we need to do further research about p-RFA.

Abstract Aim This study aims to summarize our knowledge in rectus abdominis diastasis based on the experience collected by the multidisciplinary program. Material and Methods Retrospective analysis of a prospective database. The diastasis post-pregnancy program is an interdisciplinary protocol that aims to restore the anatomical and functional structure of the abdominal wall after the degenerative process of pregnancy. Used a systematic multidisciplinary evaluation that included an abdominal walls surgeon, plastic surgeon, physiotherapist, and radiologist. Following the findings, we propose a classification, adapting the specific treatment according to the degree of the patient's condition. Grade I only performed physiotherapy; Grade II: started physiotherapy plan, with associated surgical treatment due to lack of response; Grade III underwent surgery as the first treatment in addition to physiotherapy protocol. Endoscopic-assisted linea alba reconstruction plus mesh have using to repair midline hernias in association with diastasis. Results From January 2017 and June 2019, 1085 patients completed the program. Clinical classification: Grade I: 760 patients (70 %) and Grade II: 248 patients (64%) performed physiotherapy as first-line treatment, with associated surgical treatment being necessary for 89 patients (36%); Grade III: 77 patients (7%) underwent surgery as first-line treatment, associated with physiotherapy postoperative protocol. Postoperative complications were: 31 seromas(14%) , 11 omphalitis (5%), 5 hematoma (2%) 1 (0.44%) required surgical dressing. Mc Gill and Us Check-up post-treatment test showed improvement in 77 % of patients. Please insert your text here. Conclusions Evaluation and treatment, in post-pregnant patients, using a multidisciplinary approach concept showed good initial results with important improvement anatomical, functional, clinical, and aesthetic.
