Abstract Background This is a retrospective, long-term single-center analysis of immunocompetent patients with PCNSL treated at our institution. Methods All 72 consecutive patients diagnosed with PCNSL between January 1994 and February 2005 were scheduled to receive high-dose methotrexate (HDMTX; 1.5–4 g/m2) based chemotherapy. Results The median age of the patients was 62 years, the median Karnofsky performance status (KPS) was 70%. Twelve patients did not receive HDMTX based chemotherapy due to poor physical condition or renal insufficiency. Of 60 patients treated with HDMTX based chemotherapy, 9 were followed by whole brain irradiation (WBI). Of 54 patients evaluable for response 35 (65%) responded (52% CR and 13% PR), and 19 (35%) did not. At a median follow-up of 58.7 months, median progression-free survival (PFS) was 9 months, and median overall survival (OAS) was 41.4 months. Eight patients have survived 60 months or longer (median age 48, range 19–76; median KPS 80, range 40–100), 5 of whom relapsed after primary therapy at a median of 5 months (range, 3–39.7) after initial diagnosis. According to the Memorial Sloan-Kettering Cancer Center (MSKCC) prognosis score, patients could be divided into three groups with significantly different OAS: 52.9 months for patients younger than 50 years, 42.4 months for patients ≥50 years and with KPS ≥70, and 5.2 months for patients ≥50 years and KPS <70 (p=0.009; log-rank test). Eleven of 17 patients alive without cerebral lymphoma after 27–84 months tested exhibited clinical deficits attributable to late neurotoxicity. Conclusions This study providing long-term data shows that a relatively moderate HDMTX-based chemotherapy can result in prolonged survival and probably cure even in older and early relapsing patients. However, the probability of late neurotoxicity with prolonged survival is considerable. The comparison of our results to other retrospective studies underscore the importance of treating PCNSL patients preferably at experienced institutions. The MSKCC score proved useful to predict survival.

Abstract BACKGROUNDS Primary central nervous system lymphoma (PCNSL) frequently causes severe damage of activities of daily living (ADL) and neurocognitive function (NCF) due to extensive brain infiltration, necessitating their appropriate assessment and measures even in clinical practice. Since few studies have focused on the changes in the level of ADL and NCF in the course of PCNSL treatment, we retrospectively analyzed the effect of initial treatment of PCNSL in view of ADL and NCF. METHODS Among 55 patients (13 male/9 female) with newly-diagnosed PCNSL treated in our institution from January 2014 to June 2019, 22 were evaluated with both ADL and NCF. Remission induction therapies consisted of high-dose methotrexate alone (two patients), R-MPV (rituximab, methotrexate, procarbazine, and vincristine)(17 patients), and R-MPV+radiaotherapy (three patients), according to the patients’ conditions. Rehabilitation staffs intervened from the beginning, providing specific exercises and periodically evaluating scores of Karnofsky Performance Status (KPS) and Mini Mental State Examination (MMSE). RESULTS Mean age was 68.4 yo (range 34 to 85). After induction therapies, there were 11 complete responses (CRs), eight partial responses (PRs), and three progressive diseases (PDs). Both KPS and MMSE scores improved after induction therapy, from median 70 (40–90) to 80 (50–90), and from 24 (0–30) to 27(0–30), respectively. Among three patients who underwent RT, MMSE declined in two (one CR/one PR). CONCLUSIONS Case-adjusted induction therapies resulted in significant radiographical responses, and the longitudinal evaluation of ADL and NCF by rehabilitation staffs could validate their maintenance or improvement over time through effective treatments and early rehabilitation intervention. However, three was difficulty in assessing patients with higher brain dysfunction such as aphasia and social adjustment disorder. Further study is needed to include more patients and to explore more appropriate evaluation batteries and timings during and after completion of induction therapy for PCNSL.

Abstract Objective The optimal regimen for use of high dose-methotrexate-based chemotherapy in primary central nervous system lymphoma is still under debate. We conducted a retrospective study to evaluate the treatment outcome of a combination immunochemotherapy consisting of rituximab, methotrexate, procarbazine and vincristine followed by with or without whole brain radiotherapy and consolidation cytarabine, in comparison with high dose-methotrexate monotherapy followed by full dose whole brain radiotherapy. Methods Newly diagnosed primary central nervous system lymphoma patients treated with either rituximab, methotrexate, procarbazine and vincristine or high dose-methotrexate in Kyorin University Hospital were identified, and the response rates and survival were compared. Toxicities, post-treatment transition of Mini-Mental State Examination, Karnofsky performance status score, Fazekas scale and prognostic factors were analysed in the rituximab, methotrexate, procarbazine and vincristine group. Results Ninety-five patients treated with rituximab, methotrexate, procarbazine and vincristine (n = 39) or high dose-methotrexate (n = 56) were analysed. The complete response/complete response unconfirmed rate was significantly higher in the rituximab, methotrexate, procarbazine and vincristine group (74.4 vs. 15.4%, P &lt; 0.001). Accordingly, both median progression-free survival and overall survival were significantly longer in the rituximab, methotrexate, procarbazine and vincristine group (median progression-free survival: unreached vs. 14.75 months, P &lt; 0.001) (median overall survival: unreached vs. 63.15 months, P = 0.005). Although the rate of grade 3/4 hematologic toxicities was high both during rituximab, methotrexate, procarbazine and vincristine and consolidation cytarabine, the rate of grade 3/4 infections was low, and no treatment related deaths were observed. Deterioration in Karnofsky performance status or Mini-Mental State Examination was rare, except on disease recurrence. Although whole brain radiotherapy was associated with Fazekas scale deterioration, its association with Karnofsky performance status or Mini-Mental State Examination deterioration was not significant. Conclusions Rituximab, methotrexate, procarbazine and vincristine was apparently promising in comparison with high dose-methotrexate monotherapy with manageable toxicity in this retrospective study, and further investigation is warranted.

Abstract BACKGROUND Primary central nervous system lymphoma (PCNSL) mainly affects the brain (&gt;90% of the cases), Very little data can be found in the literature on PCNSL with spinal cord localization. MATERIAL AND METHODS We present a retrospective study based on the French LOC network database. We selected adult immunocompetentpatients, with a histological or cytological diagnosis of PCNSL, and a spinal cord localization at initial diagnosis. RESULTS Of the 2043 PCNSLof the LOC database newly diagnosed since 2011, 14 patients (9 men, median age 68, median Karnofsky performance status 50%)met the selection criteria. The median diagnostic delay was 82 days (min 15-max 1080) compared to 35 days in primary cerebral lymphomas. At diagnosis, walking was impossible in 7/14 patients and 5/14 had indwelling urinary catheter. On MRI, 100% had enlargement of the spinal cord with homogeneous contrast enhancement in 13/14 cases. Spinal cord lesions were unique in 9/14 patients and multiples in 5/14 patients. CSF IL10 level was increased in 6/7 patients. Brain lesions were found in 9/14 patients, located in the posterior fossa in 5/9 cases. The diagnosis was made either on a brain biopsy (N=6), a spinal cord biopsy or surgery (N=5) or the cytologic analysis of the CSF (N=3).4/5 patients had neurological sequel after spinal cord biopsy or surgery. All the patients were treated by high-dose methotrexate-based chemotherapy, followed by spinal cord irradiation (N=1) or autograft (N=2). There was an overall response rate of 71% (complete response in 8/14). 8/14 patients relapsed, 5 in the brain, 2 in the spinal cord, and 1 both in the spinal cord and in the brain. 2-year PFS and OS were 45% and 64%, respectively. Among the long-term responders, 50% remained in wheel chair, while only 10% could walk normally. CONCLUSION Considering the high risk of a spinal cord biopsy,the rarity of the disease, as well as the numerous differential diagnoses, the diagnosis of spinal cord lymphoma is difficult. Searching for other lymphomatous locations or assaying CSF IL10 may be helpful in this disease where delay in diagnosis is often prolonged et can cause irreversible handicap.

2099 Background: Primary central nervous system lymphoma (PCNSL) is a rare aggressive variant of diffuse large B cell lymphoma (DLBCL) with a poor prognosis. Optimal therapeutic strategies have not yet been defined. High dose methotrexate (HD MTX) is an effective chemotherapeutic agent with superior outcomes compared to historical studies using whole brain radiation therapy (WBRT). Purpose: To review clinicopathologic characteristics, therapy and outcomes of 54 patients (pts) with primary CNS DLBCL. Methods: This was a single center retrospective review of pts with confirmed diagnosis of primary CNS DLBCL from 1999 to 2009. Data was extracted from the Moffitt Cancer Center (MCC) electronic records. Baseline demographics, clinical, pathological and treatment data were collected and analyzed. Pts were stratified according to their treatment regimens including HD MTX (8g/m2) alone or in combinations and WBRT alone or in combination with CT. Descriptive statistical analyses were utilized. Chi square analysis and t- test were performed to compare categorical and continuous variables. Kaplan-Meier method was used to estimate OS and log rank test was used to compare the groups. All data was analyzed using SPSS version 20.0 statistical software. Results: 54 pts who underwent CT and/or WBRT for PCNSL between 1999 and 2009 were identified. The age range at diagnosis was 19-85 years with median age of 63. 31 of 54 pts (57%) were ≥ 60 years old. Male to female ratio was 1.25 :1 (30:24). The median ECOG PS was 1. Only 2 pts had HIV. A majority of pts presented with motor deficits. The most common location of lymphoma was in the cerebral hemispheres. The median survival of the entire cohort was 42 months. 15 of 54 pts (23%) survived ≥ 60 months. In the cohort of pts that survived ≥ 60 months, a majority 11 of 15 (73%) received HD MTX. Pts treated with initial WBRT revealed inferior overall survival (OS) compared to pts treated with induction CT (OS 37 months vs. 50 months) (p=0.056). Conclusions: HD MTX was the most frequently utilized CT regimen in the cohort of pts surviving > 60 months. Administering WBRT as an initial modality was associated with worse outcomes in this retrospective analysis.

2054 Background: Primary intraocular lymphoma (PIOL) is a very rare disorder, and the optimal treatment is yet to be defined. Here, we report clinical characteristics and outcome of patients with PIOL enrolled in the prospective German PIOL registry (PIOL-R). Methods: Patient data in this prospective, non-interventional multicenter study were compiled by standardized questionnaires sent to Ophthalmology and Hematology/Oncology centers in Germany. All histologically or cytologically confirmed immunocompetent PIOL patients were eligible. Results: Fifteen patients (8 female, median age 66 years, median Karnofsky performance status 90%) from 4 centers were included between August 2008 and January 2012. Median follow-up was 7 months. Median time from first occurrence of symptoms to PIOL diagnosis was 5 (range, 1-11) months. All PIOL were of diffuse large B-cell histology. Eight patients had concomitant (n=3), prior (n=2) and/or subsequent (n=4) parenchymal brain involvement. First-line treatment included methotrexate (MTX)-, rituximab- and/or ifosfamide-based systemic chemotherapy in 12 (including high-dose chemotherapy [HDCT] with autologous stem cell transplantation [ASCT] in 2), intraocular (i.o.) chemotherapy with MTX (n=2) and/or rituximab (n=6) in 7, and ocular radiation in one patient(s). Two patients received prophylactic intrathecal (i.th.) treatment with MTX and none had whole-brain irradiation. The PIOL remission rate was 100% (complete remission in 11/14 evaluable patients and partial remission in 3 patients). Four patients relapsed in the brain after 5, 6, 21 and 23 months and received salvage treatment with MTX and/or ifosfamide (n=3) and HDCT with ASCT (n=1). No ocular or systemic relapses were observed. Median progression-free survival was 23 (95% confidence interval, 19-26) months. All patients are alive. Conclusions: Although the awareness of PIOL and diagnostic possibilities have improved over the past 2 decades, time from symptom presentation to diagnosis seems to remain at previously reported levels. There appears to be a shift from local ocular treatments and radiation to systemic therapy as compared to anecdotal data with promising response and survival rates.

Introduction Primary Central Nervous System Lymphoma (PCNSL) is a rare form of extra-nodal non-Hodgkin Lymphoma (NHL), with diffuse large B-cell Lymphoma (DLBCL) reported in 90% of cases. Secondary CNS lymphoma (SCNSL) may occur as an isolated recurrence of previously diagnosed NHL or occur simultaneously as a manifestation of systemic disease. Comparative data on survival in treated PCNSL and SCNSL in the real-world setting is lacking. We present a retrospective analysis of outcomes in PCNSL and SCNSL patients treated at the Houston Methodist Cancer Center. Methods We retrospectively identified patients with a diagnosis of PCNSL or SCNSL from 2015 to 2020. Data collected included age, race, sex, diagnosis (PCNSL, SCNSL), histology and immunohistochemistry, treatment type (chemotherapy, radiation), transplant rates as well as outcomes (alive/dead). Responses were classified as complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). Survival was analyzed using Kaplan-Meier methodology, and log-rank tests were used to compare survival distributions. P &lt; 0.05 was considered statistically significant. Results There were 50 patients with CNS lymphoma identified between 2015 and 2020; 68% were PCNSL. Out of 43 with available pathology, 2 patients were T-cell lymphomas and 41 DLBCL. Out of the DLBCL cases, 95% of cases expressed CD20 while close to 60% were positive for MUM1, bcl-2 and bcl-6. Less than 15% of cases were positive for CD10. CD30 was positive in 17% of cases. Cerebral hemispheres (76%) was the most common organ involved, followed by ocular (8%), intraventricular space (6%) and cerebellum (6%). Median age at diagnosis was 67 years; male to female ratio was 1.27. Caucasian (62%) and Hispanic (24%) were most common ethnicities. Epstein-Barr Virus was positive in 14% of patients (5 in PCNSL and 2 in SCNSL). One patient with SCNSL had human immunodeficiency virus. The median follow-up time was 9.1 months. Multiagent chemotherapy including high dose methotrexate (MTX), cytarabine and rituximab was given to 48% of the patients while 32% received high dose MTX alone plus rituximab. From the latter group, five out of sixteen patients received temozolomide. Other regimens were used in 6% of the cases. Median dose of MTX in a multiagent chemotherapy regimen was 2.5gr/m2 and 2.25gr/m2 when used alone or with temozolomide. Median number of cycles given was 3. Radiation therapy alone was given to 8% of cases. Three patients did not receive treatment. For patients with PCNSL, overall response rate (ORR) was 82.8% (CR 65.5%, PR 13.8%, SD 3.4%). ORRs were similar between multiagent chemotherapy and methotrexate alone (+/- temozolomide) with 86.7% and 83.3% respectively. ORR for SCNSL was 57.1% (CR 35.7%, PR 21.4%); only 1 patient was treated with MTX alone. Further lines of therapy were required in 9.3% of patients. Consolidation with whole brain radiation was given in 22% of the cases (29.4% for PCNSL and 6.3% for SCNSL). Autologous stem cell transplant was performed in 10% of the patients (2 PCNSL, 3 SCNSL). Overall survival for patients with PCNSL was 74.8 months and 10.1 months for SCNSL (p=0.0444) (Figure 1). Survival was not significant between patients receiving multiagent chemotherapy and MTX alone or in combination with temozolomide (3-year OS 57.3% vs 73.4%, p= 0.5652) (Figure 2). Conclusion Most patients diagnosed with PCNSL are non-germinal center DLBCL. Median MTX dose was lower than 3gr/m2 with excellent ORR of over 80% in PCNSL. Response rates were lower in SCNSL and in general, patients with PCNSL had better outcomes. Survival did not differ significantly between regimens, suggesting that a lower intensity therapy may perform similarly to multiagent chemotherapy. These results need to be confirmed by prospective studies. Disclosures No relevant conflicts of interest to declare.

PURPOSE Three trials were conducted to define the efficacy and toxicity of interferon alfa-2a in the treatment of metastatic renal cell cancer. Univariate and multivariate analyses were performed to identify prognostic factors for survival. PATIENTS AND METHODS Prospectively, 159 patients were treated with interferon alfa-2a. In the first trial, 42 patients received 50 x 10(6) U/m2 intramuscularly three times per week. In the second trial, 64 patients received gradually escalating doses of interferon alfa-2a from 3 to 36 x 10(6) U subcutaneously administered daily. The third trial was randomized; 25 patients received daily interferon alfa-2a alone and 28 were treated with daily interferon alfa-2a and 0.15 mg/kg vinblastine every 3 weeks. RESULTS The overall response proportion was 10% (two complete and 14 partial responses). The median response duration was 12.2 months. The median survival duration was 11.4 months, with 3% of patients alive at 5 or more years. A univariate statistical analysis showed that a Karnofsky performance status > or = 80, prior nephrectomy, and interval from diagnosis to treatment of longer than 365 days were significant prognostic factors for survival. In a multivariate analysis, only prior nephrectomy and Karnofsky performance status > or = 80 were shown to be independent predictors of survival. CONCLUSION Interferon alfa-2a had minimal antitumor activity in patients with advanced renal cell carcinoma and long-term survival was achieved in a small proportion of patients. The need for continued investigation and the identification of more effective therapy for advanced renal cell carcinoma is evident from the poor overall survival rate observed in these 159 patients. The investigation of new agents and of interferon alfa-2a in combination with other agents remains a priority.

ObjectiveReal-life studies on patients with primary CNS lymphoma (PCNSL) are scarce. Our objective was to analyze, in a nationwide population-based study, the current medical practice in the management of PCNSL.MethodsThe French oculo-cerebral lymphoma network (LOC) database prospectively records all newly diagnosed PCNSL cases from 32 French centers. Data of patients diagnosed between 2011 and 2016 were retrospectively analyzed.ResultsWe identified 1,002 immunocompetent patients (43% aged >70 years, median Karnofsky Performance Status [KPS] 60). First-line treatment was high-dose methotrexate-based chemotherapy in 92% of cases, with an increasing use of rituximab over time (66%). Patients <60 years of age received consolidation treatment in 77% of cases, consisting of whole-brain radiotherapy (WBRT) (54%) or high-dose chemotherapy with autologous stem cell transplantation (HCT-ASCT) (23%). Among patients >60 years of age, WBRT and HCT-ASCT consolidation were administered in only 9% and 2%, respectively. The complete response rate to initial chemotherapy was 50%. Median progression-free survival was 10.5 months. For relapse, second-line chemotherapy, HCT-ASCT, WBRT, and palliative care were offered to 55%, 17%, 10%, and 18% of patients, respectively. The median, 2-year, and 5-year overall survival was 25.3 months, 51%, and 38%, respectively (<60 years: not reached [NR], 70%, and 61%; >60 years: 15.4 months, 44%, and 28%). Age, KPS, sex, and response to induction CT were independent prognostic factors in multivariate analysis.ConclusionsOur study confirms the increasing proportion of elderly within the PCNSL population and shows comparable outcome in this population-based study with those reported by clinical trials, reflecting a notable application of recent PCNSL advances in treatment.

We report our remarks on 22 patients, 80 years of age and older, who were treated for glioblastoma multiforme. The 16 patients who underwent a multimodality treatment (surgery + radiotherapy + chemotherapy) had an average survival of 16.7 months versus the 5.8 months of the 8 patients treated with biopsy followed by radiotherapy and/or chemotherapy (log-rank test, P <0.001). Moreover, we point out the importance of MGMT hypermethylation as a significant prognostic factor: the 9 patients with nonmethylated MGMT had a mean survival of 7.7 months vs 17.9 months of the 13 patients with the MGMT promoter methylated (log-rank test, P = 0.0006). Several studies have pointed out age as an important negative factor for the outcome of elderly patients affected by glioblastoma multiforme. Elderly patients with a diagnosis of glioblastoma multiforme are thus generally excluded from clinical trials of treatment for the neoplasm, because it is a common opinion that the prognosis for such patients is particularly poor. On the contrary, according to our clinical and surgical experience, we firmly believe that patients older than 80 years with a histologically proven diagnosis of glioblastoma multiforme and in good health conditions (Karnofsky performance status >60) should be treated in the same way as younger patients.

PURPOSE Reported treatment outcomes for patients with advanced germ cell tumors (aGCT) are based mainly on series from developed nations. Data from low- and middle-income countries are underrepresented. MATERIAL AND METHODS From 2000 to 2015, a retrospective analysis identified 300 patients with aGCT treated at our institution. Kaplan-Meier methods were used for analysis of progression-free survival (PFS) and overall survival (OS) according to the International Germ Cell Consensus Classification Group (IGCCCG). RESULTS Patients’ median age was 28 years. According to the IGCCCG, 57% had good-, 18.3% intermediate-, and 24.7% poor-risk disease. Median α-fetoprotein levels were 2.9, 243, and 3,998 ng/mL, and those of human chorionic gonadotropin were 0.4, 113, and 301.5 mUI/mL in IGCCCG good-, intermediate-, and poor-risk groups, respectively. At a median 46 months of follow-up, 93 PFS events and 45 deaths had occurred and estimated 5-year PFS and OS were 69% and 85%, respectively, including 83% and 95.3% in good-risk, 70.9% and 83.6% in intermediate-risk, and 35.1% and 62.2% in poor-risk patients, respectively. In multivariable analysis, Eastern Cooperative Oncology Group performance status ≥ 2 was a significant independent prognostic factor with a hazard ratio of 2.58 (95% CI, 1.55 to 4.29; P < .001) and 6.20 (95% CI, 2.97 to 12.92; P < .001) for PFS and OS, respectively. CONCLUSION Brazilian patients with aGCT in this cohort had similar outcomes as patients in the IGCCCG database. In comparison with contemporary series, patients with intermediate- and poor-risk aGCT had slightly inferior PFS and OS, possibly due to a high percentage of patients with poor performance status and less use of high-dose chemotherapy.
