Innovative Strategies

In 2008, we reported favorable 5-year outcomes of nonmyeloablative allogeneic stem cell transplantation after fludarabine, cyclophosphamide, rituximab (FCR) conditioning for relapsed and chemosensitive follicular lymphoma. However, innovative strategies were still needed to treat patients with chemorefractory disease. We therefore subsequently performed a trial in which 90Y-ibritumomab tiuxetan (0.4 mCi/kg) was added to the fludarabine, cyclophosphamide conditioning regimen (90YFC). Here, we report updated results of the FCR trial and outcomes after 90YFC. For the FCR group (N = 47), since the last update, one patient developed recurrent disease. With a median follow-up of 107 months (range, 72-142 months), the 11-year overall survival and progression-free survival rates were 78%, and 72%, respectively. For the 90YFC group (N = 26), more patients had chemorefractory disease than did those in the FCR group (38% and 0%, P < .001). With a median follow-up of 33 months (range,17-94 months), the 3-year progression-free survival rates for patients with chemorefractory and chemosensitive disease were 80% and 87%, respectively (P = .7). The low frequency of relapse observed after a long follow-up interval of 9 years in the FCR group suggests that these patients are cured of their disease. The addition of 90Y to the conditioning regimen appears to be effective in patients with chemorefractory disease. This trial was registered at www.clinicaltrials.gov as NCT00048737.

Nonmyeloablative Stem Cell Transplantation

Abstract Nonmyeloablative stem cell transplantation in patients with follicular lymphoma has been designed to exploit the graft-versus-lymphoma immunity. The long-term effectiveness and toxicity of this strategy, however, is unknown. In this prospective study, we analyzed our 8-year experience. Patients received a conditioning regimen of fludarabine (30 mg/m2 daily for 3 days), cyclophosphamide (750 mg/m2 daily for 3 days), and rituximab (375 mg/m2 for 1 day plus 1000 mg/m2 for 3 days). They were then given an infusion of human leukocyte antigen-matched hematopoietic cells from related (n = 45) or unrelated donors (n = 2). Tacrolimus and methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. Forty-seven patients were included. All patients experienced complete remission, with only 2 relapses. With a median follow-up time of 60 months (range, 19-94), the estimated survival and progression-free survival rates were 85% and 83%, respectively. All 18 patients who were tested and had evidence of JH/bcl-2 fusion transcripts in the bone marrow at study entry experienced continuous molecular remission. The incidence of grade 2-IV acute GVHD was 11%. Only 5 patients were still undergoing immunosuppressive therapy at the time of last follow-up. We believe that the described results are a step forward toward developing a curative strategy for recurrent follicular lymphoma.

Abstract Objective: We examined the surgical approaches used at a single institution to treat petroclival meningioma and evaluated changes in method utilization over time. Methods: Craniotomies performed to treat petroclival meningioma between September of 1994 and July of 2005 were examined retrospectively. We reviewed 46 patients (mean follow-up, 3.6 yr). Techniques included combined petrosal or transcochlear approaches (15% of patients), retrosigmoid craniotomies with or without some degree of petrosectomy (59% of patients), orbitozygomatic craniotomies (7% of patients), and combined orbitozygomatic-retrosigmoid approaches (19% of patients). In 18 patients, the tumor extended supratentorially. Overall, the rate of gross total resection was 43%. Seven patients demonstrated progression over a mean of 5.9 years. No patients died. At 36 months, the progression-free survival rate for patients treated without petrosal approaches was 96%. Of 14 patients treated with stereotactic radiosurgery, none developed progression. Conclusion: Over the study period, a diminishing proportion of patients with petroclival meningioma were treated using petrosal approaches. Utilization of the orbitozygomatic and retrosigmoid approaches alone or in combination provided a viable alternative to petrosal approaches for treatment of petroclival meningioma. Regardless of approach, progression-free survival rates were excellent over short-term follow-up period.

Abstract BackgroundSoft tissue sarcoma（STS） is a malignant tumor of highly heterogeneous mesenchymal origin. STS has a biologic pattern and clinical transformation with localized invasive growth and susceptibility to hematogenous metastasis. Metastatic and recurrent soft tissue sarcoma may be treated by local therapeutic options, including surgery and radiation therapy. This study evaluated the safety and efficacy of SBRT for metastatic and recurrent soft tissue sarcoma.MethodsWe performed a retrospective analysis of 37 STS patients with 58 lesions treated with SBRT from 2009-2019 at our institution. We analyze the local control (LC), overall survival (OS), progression free survival (PFS) and toxicity rates of the patients.ResultThe median follow-up was 20 months（range 2 to 120 months）. One and two year LC rates were 75.3% and 55.2% [95% confidence interval (CI) 20–25 months]. Median OS was 24 months and the survival rates were 66.6%, 45% and 26.6% at 1, 2 and 3-year after SBRT. Median PFS were 11months (95% CI 8–18 months). No acute or chronic grade ≥ 3 toxicity was observed.ConclusionsIn patients with metastatic and recurrent STS, LC, OS and PFS were higher than expected. SBRT should be a proper treatment option for STS.

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 Patients with recurrent and refractory multiple myeloma have a very limited survival expectance. Allogeneic transplantation might offer an option for cure in myeloma and the recent development of non-myeloablative conditioning regimens has reduced transplant related morbidity and mortality and rendered this treatment feasible in elderly patients. The role of non-myeloablative allogeneic transplantation for multiple myeloma however, has not yet been defined. We have analyzed the results of patients with relapsed or refractory multiple myeloma treated at our institution. Between 08/1999 and 02/2004, 56 patients with relapsed (n=54) or refractory (n=2) myeloma were treated with non-myeloablative allogeneic transplantation. The median beta2microglobulin at the time of diagnosis was 2.75 mg/l, and median age at the time of transplant was 54.5 years (39.2–67.8). The median time from diagnosis to transplant was 3.6 years. Prior to allogeneic transplantation, patients received reinduction chemotherapy which included an autologous transplantation for 30 patients. The median number of previous cycles of conventional chemotherapy was 9. The conditioning regimen was 2 Gy TBI with (n=43) or without (n=3) fludarabin 3 x 30 mg/m² for 46 patients, the remaining 10 patients received a melphalan containing regimen. Acute toxicity was low with a WBC &lt; 500/μl and platelets &lt; 50/μl for a median of 0 days. Engraftment was prompt with 90 % of patients having achieved &gt; 90 % donor chimerism by day 56. Acute GvHD Grade II-IV occurred in 36 % of patients with 22 % Grade III-IV, and 61 % experienced chronic GvHD. Total transplant related mortality reached 20 %, with a day 100 TRM of 5 %. 32 patients experienced relapse or progressive disease, and 32 % of patients died due to relapse. The Kaplan-Meier estimate of overall survival and progression free survival at 18 months was 40 % and 25 %, respectively, with a median follow up of survivors of 21 months. Patients who experienced cGvHD had a significantly higher overall survival estimate (60 % vs. 20 % at 18 months, p=0.03). The number of cycles of pretreatment before allogeneic transplantation had a statistically significant negative influence on overall (p=0.02) and progression free survival (p=0.006). We conclude that non-myeloablative allogeneic transplantation is feasible in patients with relapsed multiple myeloma. The significant poor prognostic factors we identified were absence of chronic GvHD and number of cycles of pretreatment. Allogeneic transplantion should therefore be considered as an option earlier in the course of the disease.

Abstract Follicular lymphoma (FL) patients, (pts) with high-risk features using the FL International Prognostic Index (FLIPI) have an expected 5-year survival of only about 50% with conventional therapy. With the incorporation of anti-CD20 monoclonal antibody (mAb) therapy, results are improving (e.g., Buske, Blood2006; 108: 1504). Starting in 2003, we have treated high-risk (FLIPI ≥3) FL pts with R-FND (rituximab, fludarabine, mitoxantrone, dexamethasone) for 4 cycles, followed by radioimmunotherapy (RIT) with ibritumomab tiuxetan, and subsequent rituximab maintenance. Results for the first 35 pts are: complete (CR) and partial (PR) remission 83% and 14%; 3-year overall (OS) and failure-free survival (FFS) 89% and 74% (median follow-up 24 mo.). RIT converted 5 PR pts to CR. Toxicity was mainly hematologic. Five pts did not receive RIT, one because of neutropenia after R-FND. Following RIT, platelet and neutrophil nadirs were 28 and 0.3, occurring at 4–7 weeks. 16 pts required transfusions, and 27 received growth factors. 13 pts had infections, only 2 of which were grade 3. Recovery occurred by 3 weeks in most, with prolonged cytopenias in 6. There has been 1 case of myelodysplasia. In conclusion, the additional complexity of this RIT intensification strategy is warranted in this high-risk FL population, resulting in OS and FFS outcomes that are better than non-mAb therapies, and at least as good as published chemotherapy-rituximab combination therapy.

e17543 Background: Bronchial neuroendocrine tumours, represent 1–3% of all primary lung tumours and 25% of all neuroendocrine tumours (NETs). They are classified into: typical carcinoids (TC), atypical carcinoids (AC), large cell neuroendocrine carcinomas (LCNEC) and small cell lung carcinomas (SCLC). The aim of our study was to assess diagnostic features, management and outcome, focusing on the differences between TC and AC. Methods: 116 patients were identified from our NET database. WHO histopathological classification was used. Follow-up was complete in all patients (mean follow-up 59.8 months). Disease-free survival (DFS), and progression-free survival (PFS) were evaluated for each therapy. Results: The average age of presentation was 55.30 years (range 16-85 years, M:F ratio=1:1.5). The commonest presenting symptom was cough (19%) followed by haemoptysis (18%). 36% were TC, 45% AC, and 19% LCNEC/SCLC. 16% TC and 28% AC patients had metastases at diagnosis. Octreoscan was positive in 76% TC and 66% AC. In 2 patients with TC and negative Octreoscan, Ga-68 Octreotate PET showed avid uptake in lung lesions. 46 patients had surgery. In 35 of AC, the disease relapsed (DFS=29.8 months) compared to 24% TC (DFS=48months). 12 patients received somatostatin analogues (SSTA) with PFS for TC 60 months and AC 21 months. 16 patients received systemic chemotherapy with PFS for TC 72 months and AC 21 months. 4/5 patients achieved disease stability with 90Yttrium-DOTAoctreotate. 5-years survival after surgery, chemotherapy or SSTA, was 91%, 86% and 81% respectively. Overall five year survival was 91% (100 % TC, 75% AC). Conclusions: AC and SCLC/LCLC more often present with metastatic disease with shorter DFS and PFS compared to TC. Molecular imaging is helpful for staging and predicting appropriateness for SSTA or radionuclide targeted therapy. Surgery confers the best survival rates. AC have higher relapse rates and metastatic potential. Further clinical trials are required to define the best treatment algorithm.

Purpose The aim of the F2 study was to verify whether a prospective collection of data would enable the development of a more accurate prognostic index for follicular lymphoma (FL) by using parameters which could not be retrospectively studied before, and by choosing progression-free survival (PFS) as principal end point. Patients and Methods Between January 2003 and May 2005, 1,093 patients with a newly diagnosed FL were registered and 942 individuals receiving antilymphoma therapy were selected as the study population. The variables we used for score definition were selected by means of bootstrap resampling procedures on 832 patients with complete data. Procedures to select the model that would minimize errors were also performed. Results After a median follow-up of 38 months, 261 events for PFS evaluation were recorded. β2-microglobulin higher than the upper limit of normal, longest diameter of the largest involved node longer than 6 cm, bone marrow involvement, hemoglobin level lower than 12 g/dL, and age older than 60 years were factors independently predictive for PFS. Using these variables, a prognostic model was devised to identify three groups at different levels of risk. The 3-year PFS rate was 91%, 69%, and 51% for patients at low, intermediate, and high risk, respectively (log-rank = 64.6; P < .00001). The 3-year survival rate was 99%, 96%, and 84% for patients at low, intermediate, and high risk, respectively (P < .0001). Conclusion Follicular Lymphoma International Prognostic Index 2 is a simple prognostic index based on easily available clinical data and may represent a promising new tool for the identification of patients with FL at different risk in the era of immunochemotherapy.

Abstract Background: This retrospective analysis is focused on the efficacy and safety of radioimmunotherapy (RIT) with Zevalin® in nine patients with recurrent follicular lymphoma (FL) who were treated in a consolidation setting after having achieved complete remission or partial remission with FCR. Methods: The median age was 63 years (range 46-77), all patients were relapsed with histologically confirmed CD20-positive (grade 1 or 2) FL, at relapse they received FCR every 28 days: F (25mg/m2x 3 days), C (1gr/m2 day 1) and R (375mg/m2 day 4) for 4 cycles. Who achieved at least a partial remission, with<25% bone marrow involvement, was treated with 90Yttrium Ibritumomab Tiuxetan 11.1 or 14.8 MBq/Kg up to a maximum dose 1184 MBq, at 3 months after the completion of FCR. The patients underwent a further restaging at 12 weeks after 90Y-RIT with total body CT scan, FDG-PET/CT and bilateral bone marrow biopsy. Results: Nine patients have completed the treatment: FCR followed by 90Y-RIT (6 patients at 14.8 MBq/Kg, 3 patients at 11.1 MBq/Kg). After FCR 7 patients obtained CR and 2 PR; after 90Y-RIT two patients in PR converted to CR 12 weeks later. With median follow up of 86 months (range 20-107) since FCR and 79 months (range13-97) since RIT, 3 deaths were observed not related to lymphoma: one for acute renal failure, one for ictus cerebri and one for sepsis; all three deceased patients obtained CR before 90Y-RIT and died still in CR. The median overall survival (OS) and progression free survival (PFS) have not been reached , current analysis has shown that either OS or PFS are 67% at 7 year. The most common grade 3 or 4 adverse events were hematologic, one patient developed herpes zoster infection after 8 months following valacyclovir discontinuation; another patient developed fungal infection. Conclusions: These results confirm the long term efficacy and safety of 4 cycles of FCR followed by consolidation with 90Y-RIT in patients relapsed with grades 1 and 2 FL and suggest that this regimen could be an option to be used for treatment in this setting of patients, specially at age of 60-75 with no unexpected toxicities.

Abstract Abstract 1785 Background: The sequential combination of chemotherapy and radioimmunotherapy has been shown to be effective front-line treatment for patients with follicular lymphoma (FL). We report ten-year followup results of a phase II trial of abbreviated fludarabine followed by tositumomab and I-131 tositumomab in patients with untreated follicular lymphoma. Methods: Patients with untreated follicular lymphoma received fludarabine 25 mg/m2/d for five days every five weeks for three cycles followed in six to eight weeks by tositumomab and I-131 tositumomab. Results: Thirty-eight patients were enrolled. One patient was withdrawn due to ineligible histology. The median age of eligible patients was 53 years, median time from diagnosis was 3.5 months, and 43% of patients had a high-risk FLIPI score. Two patients did not receive radioimmunotherapy; one patient had a myocardial infarction during fludarabine and was not evaluable, and one patient had persistent cytopenias following three cycles of fludarabine. All 35 patients that completed the regimen responded (ORR 100%). With a median follow-up of 128.5 months for all 37 eligible patients, the 10-year intent-to-treat overall survival is 69% and the progression-free survival is 51%. Seventeen patients have progressed (range 2–102 months). Sixteen patients remain in remission with no evidence of disease more than ten years from enrollment. Only four patients have relapsed beyond five years. Four patients have developed MDS (range 16–84 months), one of whom evolved to AML. Conclusions: Fludarabine followed by tositumomab and I-131 tositumomab is very effective at inducing long-lasting complete remissions in FL. The efficacy and long-term safety of sequential chemotherapy plus radioimmunotherapy should continue to be evaluated in the context of the range of therapeutic options for the initial treatment of follicular lymphoma.
