The temozolomide protocol established in 2005 increased overall survival rates in patients with glioblastoma. It defined a treatment period of 6 months, but most neuro-oncological centers prescribe more than this, reaching up to 3 years of continuous therapy. The objective of this paper was to compare duration of treatment in groups of patients and analyze the overall survival in each group. Retrospectively, 54 patients were evaluated with glioblastoma operated on from 2004 to 2009. All data were statistically analyzed using Kaplan-Meier curves, ANOVA test, multivariate logistic regression models and Pearson´s correlation. Analyses consisted on age, gender, Karnofsky Performance Scale (KPS) at diagnosis, side and localization of tumor, grade of surgical removal, period of use of temozolomide until recurrence, progression-free survival, KPS after recurrence and overall survival. According to uni and multi-varied analysis there was no statistic significant correlation between survival and age < 45, gender, KPS at diagnosis, and grade of resection. The overall survival in 6, 12, 18 and 24 months were 96.3%, 72.6%, 58.1% and 43.5% respectively. The length of treatment with temozolomide before recurrence showed strong positive correlation (r=0.66) with survival up to 15 months. Also, a correlation (r=0.64) between length of use of temozolomide and progression free-survival was found. Patients receiving treatment with temozolomide presented longer survival when compared with those not treated with it. Longer survival (p=0.04) was observed in those treated more than 12 months. This series could clearly show longer survival in patients treated with 15-cicles over patients treated with 6 or 12-cicles.

Oligometastatic Disease

IntroductionData supporting stereotactic body radiotherapy for oligometastatic patients are increasing; however, the outcomes for gynecological cancer patients have yet to be fully explored. Our aim is to analyze the clinical outcomes of stereotactic body radiotherapy in the treatment of patients with recurrent or oligometastatic ovarian cancer or cervical cancer.MethodsThe clinical data of 29 patients (35 lesions) with oligometastatic cervical cancer (21 patients, 72%) and ovarian carcinoma (8 patients, 28%) who were treated with stereotactic body radiotherapy for metastatic sites were retrospectively evaluated. All patients had <5 metastases at diagnosis or during progression, and were treated with stereotactic body radiotherapy for oligometastatic disease. Patients with ≥5 metastases or with brain metastases and those who underwent re-irradiation for primary site were excluded. Age, progression time, mean biologically effective dose, and treatment response were compared for overall survival and progression-free survival.ResultsA total of 29 patients were included in the study. De novo oligometastatic disease was observed in 7 patients (24%), and 22 patients (76%) had oligoprogression. The median follow-up was 15.3 months (range 1.9–95.2). The 1 and 2 year overall survival rates were 85% and 62%, respectively, and the 1 and 2 year progression-free survival rates were 27% and 18%, respectively. The 1 and 2 year local control rates for all patients were 84% and 84%, respectively. All disease progressions were observed at a median time of 7.7 months (range 1.0–16.0) after the completion of stereotactic body radiotherapy. Patients with a complete response after stereotactic body radiotherapy for oligometastasis had a significantly higher 2 year overall survival and progression-free survival compared with their counterparts. In multivariate analysis, early progression (≤12 months) and complete response after stereotactic body radiotherapy for oligometastasis were the significant prognostic factors for improved overall survival. However, no significant factor was found for progression-free survival in the multivariable analysis. No patients experienced grade 3 or higher acute or late toxicities.ConclusionsPatients with early detection of oligometastasis (≤12 months) and with complete response observed at the stereotactic body radiotherapy site had a better survival compared with their counterparts. Stereotactic body radiotherapy at the oligometastatic site resulted in excellent local control rates with minimal toxicity, and can potentially contribute to long-term survival.

ObjectiveTo analyze the prognostic factors and treatment outcomes in endometrial cancer patients with paraaortic lymph node metastasis.MethodsData from four centers were collected retrospectively for 92 patients with endometrial cancer treated with combined radiotherapy and chemotherapy or adjuvant radiotherapy alone postoperatively, delivered by either the sandwich or sequential method. Prognostic factors affecting overall survival and progression-free survival were analyzed.ResultsThe 5-year overall survival and progression-free survival rates were 35 % and 33 %, respectively, after a median follow-up time of 33 months. The 5-year overall survival and progression-free survival rates were significantly higher in patients receiving radiotherapy and chemotherapy postoperatively compared with patients treated with adjuvant radiotherapy alone (P < 0.001 and P < 0.001, respectively). In a subgroup analysis of patients treated with adjuvant combined chemotherapy and radiotherapy, the 5-year overall survival and progression-free survival rates were significantly higher in patients receiving chemotherapy and radiotherapy via the sandwich method compared with patients treated with sequential chemotherapy and radiotherapy (P = 0.02 and P = 0.03, respectively). In the univariate analysis, in addition to treatment strategy, pathology, depth of myometrial invasion, and tumor grade were significant prognostic factors for both overall survival and progression-free survival. In the multivariate analysis, grade III disease, myometrial invasion greater than or equal to 50%, and adjuvant radiotherapy alone were negative predictors for both overall survival and progression-free survival.ConclusionWe demonstrated that adjuvant combined treatment including radiotherapyand chemotherapy significantly increases overall survival and progression-free survival rates compared with postoperative pelvic and paraaortic radiotherapy.

Retrospective Multicenter Study

Background. Lenvatinib has proven efficacy in progressive, radioiodine- (RAI-) refractory thyroid cancer (TC). Dose reductions are commonly performed due to decreased tolerability and adverse effects. This retrospective multicenter study analyzed overall survival (OS) and progression-free survival (PFS) and tolerability in the Austrian patient population treated with lenvatinib. Methods. Clinical data of 43 patients (25 males and 18 females) with a median age of 70 years (range: 39–91 years) and RAI-refractory TC with metastases to the lymph nodes (74%), lungs (86%), bone (35%), liver (16%), and brain (12%) were analyzed. The mean duration of treatment with lenvatinib was 26.6 ± 15.4 months with dosage reductions required in 39 patients (91%). Results. PFS after 24 months was 71% (95% CI: 56–87), and overall survival (OS) was 74% (95% CI: 60–88), respectively. OS was significantly shorter ( p = 0.048 ) in patients with a daily maintenance dosage ≤ 10 mg (63%) (95% CI: 39–86) as compared to patients on ≥ 14 mg lenvatinib (82%) (95% CI: 66–98) daily. Dose reduction was noted in 39 patients (91%). Grade ≥3 toxicities (hypertension, diarrhea, weight loss, and palmar-plantar erythrodysesthesia syndrome) were most common leading to discontinuation of lenvatinib in 7 patients (16%). Conclusion. Lenvatinib showed sustained clinical efficacy in patients with metastatic RAI-refractory TC even with reduced maintenance dosages over years. The effects were comparable to the registration trial, although patients had a higher median age and, more commonly, dose reductions.

Purpose To determine whether addition of the farnesyltransferase inhibitor tipifarnib (Zarnestra, R115777; Johnson and Johnson Pharmaceutical Research and Development, Beerse, Belgium) to standard gemcitabine therapy improves overall survival in advanced pancreatic cancer. Patients and Methods This randomized, double-blind, placebo-controlled study compared gemcitabine + tipifarnib versus gemcitabine + placebo in patients with advanced pancreatic adenocarcinoma previously untreated with systemic therapy. Tipifarnib was given at 200 mg bid orally continuously; gemcitabine was given at 1,000 mg/m2 intravenously weekly × 7 for 8 weeks, then weekly × 3 every 4 weeks. The primary end point was overall survival; secondary end points included 6-month and 1-year survival rates, progression-free survival, response rate, safety, and quality of life. Results Six hundred eighty-eight patients were enrolled. Baseline characteristics were well balanced between the two treatment arms. No statistically significant differences in survival parameters were observed. The median overall survival for the experimental arm was 193 v 182 days for the control arm (P = .75); 6-month and 1-year survival rates were 53% and 27% v 49% and 24% for the control arm, respectively; median progression-free survival was 112 v 109 days for the control arm. Ten drug-related deaths were reported for the experimental arm and seven for the control arm. Neutropenia and thrombocytopenia grade ≥ 3 were observed in 40% and 15% in the experimental arm versus 30% and 12% in the control arm. Incidences of nonhematologic adverse events were similar in two groups. Conclusion The combination of gemcitabine and tipifarnib has an acceptable toxicity profile but does not prolong overall survival in advanced pancreatic cancer compared with single-agent gemcitabine.

Abstract Rearrangements of the c-myc oncogene can be seen in 5–10% of patients with diffuse large B-cell lymphoma. However, studies examining the significance of this finding have yielded conflicting results. Therefore, we performed a retrospective analysis to determine the clinical significance of c-myc rearrangements in diffuse large B-cell lymphoma. The results of classical cytogenetic studies and FISH analyses were used to identify diffuse large B-cell lymphoma cases in the database of the Nebraska Lymphoma Study Group with or without c-myc rearrangements. Patients who were HIV positive and those with post-transplant lymphoproliferative disease were excluded. We identified 16 patients with diffuse large B-cell lymphoma and c-myc rearrangements. All patients were initially treated with doxorubicin- or mitoxantrone-containing chemotherapy regimens. The median age of these 16 patients was 61 years (range 40 to 80), and 5 (31%) were males. The International Prognostic Index (IPI) was 0–2 at diagnosis in 9 patients (56%), and 3–5 in 7 patients (44%). Eleven patients (69%) had bulky disease (≥ 5 cm) at diagnosis. No significant differences in outcome were identified when the 16 c-myc positive patients were compared with 97 c-myc negative diffuse large B-cell lymphoma patients in the same age range. The actuarial 5-year progression-free survival for the c-myc positive patients was 23% (95% CI 6% to 46%), as compared with 38% (95% CI 29% to 48%) for c-myc negative patients (p=0.17). The actuarial 5-year overall survival rates were 36% (95% CI 14% to 59%) and 47% (95% CI 36% to 56%), respectively (p=0.19). Classical cytogenetics and FISH analyses were also used to examine the 16 c-myc positive cases for bcl-2 rearrangements. Eight (50%) cases had rearrangements of bcl-2 in addition to c-myc rearrangements. These patients were similar to the c-myc positive/bcl-2 negative patients except for a higher likelihood of an elevated LDH level at diagnosis (88% vs. 25%; p=0.03). The actuarial 5-year progression-free survival for c-myc positive/bcl-2 positive patients was 0%, as compared to 33% (95% CI 6% to 66%) for patients with rearrangements of c-myc alone, and 37% (95% CI 28% to 47%) for c-myc negative patients. The actuarial 5-year overall survival rates were 12% (95% CI 1% to 42%), 47% (95% CI 12% to 76%), and 41% (95% CI 31% to 51%), respectively. A multivariate analysis, adjusting for IPI score, demonstrated that the relative risk (RR) of treatment failure was significantly worse for the c-myc positive/bcl-2 positive patients, as compared to the c-myc negative patients (RR 2.86, 95% CI 1.32–6.23; p=0.008). Similarly, mortality was also significantly worse for the c-myc positive/bcl-2 positive patients, as compared to the c-myc negative patients (RR 2.69, 95% CI 1.18–6.11; p=0.02). In contrast, no significant differences in treatment failure or overall survival were demonstrated when c-myc positive/bcl-2 negative patients were compared with c-myc negative patients. Our results demonstrate that the c-myc rearrangement is not associated with poorer survival in patients with diffuse large B-cell lymphoma. However, patients with rearrangements of bcl-2 in addition to c-myc had significantly worse progression-free survival and overall survival.

The Impact

7502 Background: Rituximab (R) prolongs the progression-free survival (PFS) in patients with follicular lymphoma (FL) when given either simultaneously with or as maintenance after chemotherapy only. Methods: In the current study the impact of R maintenance after remission induction with an R-containing combined immuno-chemotherapy (R-FCM) was evaluated. Patients with advanced stage relapsed or refractory FL and mantle cell lymphoma (MCL) were eligible. The study design comprized 4 courses of chemotherapy with Fludarabine (25 mg/m2/d days 1–3), Cyclophosphamide (200 mg/m2/d days 1–3) and Mitoxantrone (8 mg/m2/d day 1) (FCM) ± Rituximab (375 mg/m2/d day 0). Patients entering a complete (CR) or partial remission (PR) underwent a second randomization for R maintenance (4 weekly doses (375 mg/m2/d) at three and nine months after end of induction) or observation only. Randomization was stratified for histology, prior therapies (up to 2 lines vs. >2), induction (±R), and response (CR vs. PR). After improved outcome of the R-FCM arm had been observed in the initial 147 randomized patients, all subsequent patients received a combined immuno-chemotherapy induction. Results: 176 of 195 randomized cases are evaluable, 138 of whom had received an R-containing induction. In these patients (as well as the total group) the median PFS after end of induction has not been reached in the R-maintenance arm in contrast to 17 months in patients with no further treatment (p = 0.001). This improvement was seen both in FL (n = 81; p = 0,035) and MCL (n = 47; p = 0,049). More importantly, overall survival rate was also improved after R maintenance with borderline significance (3 y rate 82% vs. 55%; p = 0,056). No major sided effects of R maintenance have been observed and the rate of serious infections was similar in both study arms (p = 0.72). Conclusions: The final analysis of this study confirms that R maintenance after combined immuno-chemotherapy (R-FCM) is highly effective and improves the progression-free survival—with a strong trend towards improved overall survival—of patients with relapsed FL and MCL.

Introduction. Hepatocellular carcinoma (HCC) is the most common primary malignant neoplasm of the liver. During the early stages, HCC is asymptomatic, which makes X-ray examination a particularly important diagnostic tool. According to WHO data, the mortality rate from HCC was 782,000 in 2018. HCC is associated with a number of risk factors: a high viral load, liver cirrhosis, detected HBeAg and elevated serum HBsAg levels. Inhibitors of tyrosine kinase receptors increase the overall survival and progression-free survival rates in patients with metastatic HCC. In this article, we conduct an analysis of results of the REFLECT study obtained for Russian patients by the Republican Clinical Oncological Dispensary, Ufa.Materials and methods. The experimental group included 9 patients (52.9%) receiving Lenvatinib. The control group included 8 patients (47.1%)) underwent therapy with Sorafenib at a dose of 800 mg per day 7 (41.17%) patients had a history of chronic hepatitis, of which hepatitis B and chronic hepatitis C was confirmed in 6 and 1 cases, respectively.Results and discussion. Over the period from 2017 up to the present, progression-free survival was observed in three patients (17.6%), of which 2 and 1 received Lenvatinib and Sorafenib, respectively. Overall survival was 10.5 months. The median overall survival rate in the experimental and control groups was 9.8 and 11.2 months, respectively. These parameters are considered comparable, provided that the sample was small.Conclusions. The use of Lenvatinib demonstrated the efficacy comparable to that of Sorafenib in terms of the overall survival rate in patients with inoperable HCC. Lenvatinib allowed statistically and clinically significant improvement in the progression-free survival and time to progression to be achieved.

Prognostic Assessment

Background and objectives: Our aim is to explore the relationship between the levels of protein encoded by Ki67 and the histopathological aspects regarding the overall survival and progression-free survival in a single university center. A secondary objective was to examine other factors that can influence these endpoints. New approaches to the prognostic assessment of breast cancer have come from molecular profiling studies. Ki67 is a nuclear protein associated with cell proliferation. Together with the histological type and tumor grade, it is used to appreciate the aggressiveness of the breast tumors. Materials and Methods: We conducted a retrospective single-institution study, at Elias University Emergency Hospital, Bucharest, Romania, in which we enrolled women with stage I to III breast cancer. The protocol was amended to include the immunohistochemistry determination of Ki67 and the histological aspects. The methodology consisted in using a Kaplan–Meier analysis for the entire sample and restricted mean survival time up to 36 months. Results: Both lower Ki67 and low tumor grade are associated with better prognosis in terms of overall survival (OS) and progression-free survival (PFS) for our patients’ cohort. In our group, the histological type did not impact the time to progression or survival. Conclusions: Both overall survival and progression-free survival may be influenced by the higher value of Ki67 and less differentiated tumors. Further studies are needed in order to establish if the histologic type may impact breast cancer prognostic, probably together with other histologic and molecular markers.

One hundred twenty-eight patients with purely nodular lymphocytic poorly differentiated lymphoma (NLPDL) without any prior therapy, entered on Eastern Cooperative Oncology Group protocol EST 2474, were analyzed for response, progression-free and overall survival. The restaged complete response rates with cyclophosphamide-prednisone (CP) (moderate regimen) of 54% compared favorably with those of the more intensive regimens; cyclophosphamide, vincristine, procarbazine and prednisone (COPP) (56%) and BCNU, cyclophosphamide, vincristine, and prednisone (BCVP) (53%). The toxicity of the regimens decreased from BCVP to COPP to CP. The median survival rate for the entire group was 7.8 years. Estimated progression-free survival at five years by regimen was COPP, 57%; BCVP, 26%; CP, 22% (P = .02). No other prognostic parameter significantly affected progression-free survival. In spite of the better progression-free survival of COPP-treated patients, the overall survival rates with the different induction regimens were similar. Maintenance therapy for patients in complete response at the end of induction therapy with periodic BCVP reinduction did not significantly affect the disease-free or overall survival. Cyclophosphamide-prednisone is a minimally toxic regimen effective in the treatment of NLPDL, but COPP, in view of its acceptable toxicity in this patient population and apparent superiority in providing a longer disease-free state, deserves further testing.

11073 Background: To observe the effect of ultrasound / CT guided radioactive 125I seed implantation in the treatment of recurrent soft tissue sarcoma and its relationship with physical dosimetry prognostic factors. Methods: The data of 37 patients with recurrent soft tissue sarcoma who received ultrasound/CT-guided 125I seed implantation from November 2005 to December 2015 were retrospectively analyzed. The local progression-free survival rate and overall survival rate were evaluated. The relationship of local progression-free survival rate and overall survival with physical dosimetric parameters was analyzed. Results: Thirty-seven patients, 20 males and 17 females, with a median age of 53 years (16-79 years), received a median radiation dose of 60 Gy (28 Gy-120 Gy). The median tumor volume was 46.8 cm3 (0.5-252.2 cm3), the median particle activity was 0.67 mCi (0.4-0.84 mCi), and the median implanted particle number was 60 (3-158). The median follow-up time was 20 months (range: 1~144 months). The median overall survival time was 20.0 months (95% CI 16.4-23.6 months). The overall survival rates of 1, 3 and 5 years were 62.2%, 34.3% and 27.7% respectively. The median local progression-free time was 63.0 months. The 1-year, 3-year and 5-year local progression-free survival rates were 68.9%, 55.0% and 47.1%, respectively. Correlation analysis showed that HI was positively correlated with total survival and local progression-free survival (P = 0.001). Multivariate analysis showed that HI ( > 0.25) was an independent prognostic factor for long overall survival (P = 0.048, HR 0.39), and D90 ( > 110 Gy) was an independent prognostic factor for long local progression-free survival (P = 0.024, HR 0.17). Conclusions: Ultrasound/CT guided 125I seed implantation is a safe and effective method for the treatment of recurrent soft tissue sarcoma with high local control rate. The HI and D90 of the postoperative plan maybe affect the therapeutic efficacy.
