Relapse patterns in pediatric embryonal central nervous system tumors

To evaluate in a single center retrospectively the efficacy and tolerability of a weekly regimen, which alternates temozolomide (TMZ) in patients with recurrent or progressive high-grade glioma (HGG). From January 2005 until June 2011, 54 patients with recurrent or progressive HGG were treated with TMZ 150 mg/m²/day on days 1–7 and 15–21 of a 28-day cycle (“one week on–one week off” scheme; TMZ 7/14) with individual dose adjustment depending on toxicity. The majority of patients (n = 48, 89 %) was treated at first tumor recurrence or progression. All patients had received prior radiotherapy with or without concomitantly administered TMZ and, optionally, adjuvant chemotherapy. After initiation of TMZ 7/14, MRI was obtained every 8–12 weeks. Tumor response or progression was assessed according to Macdonald criteria. Blood examinations were performed weekly. Toxicity was evaluated according to Common Terminology Criteria for Adverse Events (CTCAE; version 3.0). A total of 434 treatment weeks with TMZ 7/14 were delivered. The median number of treatment weeks was 7 (range, 1–41 weeks). No grade 4 hematological toxicity and no opportunistic infections occurred. Patients with neutropenia were not observed. Two patients developed grade 3 and 4 patients grade 2 leukocytopenia. Thrombocytopenia grade 3 and grade 2 occurred in 4 patients and 6 patients, respectively. The progression-free survival (PFS) rate at 6 months was 43 %. Median PFS from treatment initiation was 18 weeks (95 % CI, 14–22 weeks) and median overall survival (OS) was 37 weeks (95 % CI, 31–42 weeks). The rates for PFS and OS at 1 year were 24 and 28 %, respectively. Our data suggest that treatment with TMZ 7/14 is safe and effective in patients with recurrent or progressive HGG.     

Hypofractionated stereotactic radiotherapy and continuous low-dose temozolomide in patients with recurrent or progressive malignant gliomas

To evaluate the efficacy of reirradiation and systemic chemotherapy as salvage treatment in patients with recurrent malignant glioma. Between May 2006 and December 2011, 54 patients with recurrent malignant glioma received hypofractionated stereotactic radiotherapy (HSRT) plus systemic therapy at University of Rome Sapienza, Sant’ Andrea Hospital. All patients had Karnofsky performance score ≥60 and were previously treated with standard conformal RT (60 Gy) with concomitant and adjuvant temozolomide (TMZ) up to 12 cycles. Thirty-eight patients had a GBM and 16 patients had a grade 3 glioma. The median time interval between primary RT and reirradiation was 15.5 months. At the time of recurrence all patients received HSRT (30 Gy in 6-Gy fractions) plus concomitant TMZ (75 mg/m²/day) followed by continuous TMZ at 50 mg/m² everyday up to 1 year or until progression. Median overall survival after HSRT was 12.4 months, and the 12- and 24-month survival rates were 53 and 16 %, respectively. The median progression-free survival (PFS) was 6 months, and the 12- and 24-month PFS rates were 24 and 10 %, respectively. KPS >70 (P = 0.04) and grade 3 glioma were independent favourable prognostic factors for survival. In general chemoradiation regimen was well tolerated with relatively low treatment-related toxicity. HSRT plus concomitant TMZ followed by continuous dose-intense TMZ is a feasible treatment option associated with survival benefits and low risk of complications in selected patients with recurrent malignant glioma. The potential advantages of combined chemoradiation schedules in patients with recurrent malignant gliomas need to be explored in future studies.

3-D conformal radiotherapy with concomitant and adjuvant temozolomide for patients with glioblastoma multiforme and evaluation of prognostic factors

Background

The aim of the retrospective study was to evaluate the outcome and prognostic factors of newly diagnosed glioblastoma patients who received 3-D conformal radiotherapy (RT) combined with concomitant and/or adjuvant temozalamide (TMZ) postoperatively.

Patients and methods

Fifty patients with glioblastoma multiforme were treated with 3-D conformal RT combined with concomitant and/or adjuvant TMZ postoperatively. Median age was 57 years (range, 12–79) and median Karnofsky performance status (KPS) was 70 (range, 40–100). A multivariate Cox regression model was used to test the effect of age, sex, KPS, extent of surgery, tumour dimension (<5cm vs. ≥5cm), full dose RT (≥60 Gy vs. <60 Gy), concurrent TMZ and adjuvant TMZ treatment (adjuvant therapy plus 6 cycles of TMZ group versus <6 cycles of TMZ group) on the overall survival.

Results

The median follow up time was 10 months (range 3–42). One- and 2-year overall survival rates were 46% and 20%, respectively. The prognostic factors important for the overall survival were a full dose RT (≥60 Gy) (p=0.005) and the application of adjuvant TMZ for 6 cycles (p=0.009).

Conclusions

The results of our study confirm the efficiency of RT plus concomitant and adjuvant TMZ, with an acceptable toxicity in patients. We suggest that at least 6 cycles of adjuvant TMZ should be administered to obtain a benefit from the adjuvant treatment.

From October 2004 to August 2010, total 1,285 patients were diagnosed as glioma at the Glioma Center of Beijing Tiantan Hospital. Clinical and molecular pathology features and survival rates were analyzed. The median overall survival (OS) times were 78.1, 37.6 and 14.4 months for low-grade glioma (WHO grade II), anaplastic glioma (WHO grade III) and glioblastoma (WHO grade IV), respectively. In patients with low-grade glioma, age, preoperative Karnofsky performance scale (KPS), pathological type, radiotherapy, O⁶-methylguanine-DNA methyltransferase (MGMT) expression and Ki-67 expression, were significantly associated with OS in multivariate analyses; and preoperative KPS and radiotherapy were significantly associated with progression-free survival (PFS). For anaplastic gliomas, age, preoperative KPS, pathological type, extent of resection, radiotherapy, p53 expression and phosphatase and tensin homolog (PTEN) expression were associated with OS. For glioblastomas, age, preoperative KPS, pathology type, extent of resection, radiotherapy and chemotherapy were associated with OS; and age, gender, preoperative KPS, extent of resection, radiotherapy and chemotherapy were associated with PFS. This is the largest survey for glioma management in China to date. We found significant differences in age, presenting symptoms and the expression of p53, MGMT, PTEN, and Ki-67 among patients with different types of glioma. Age, preoperative KPS, tumor grades, radiotherapy, chemotherapy and Ki-67 expression were significantly associated with clinical prognosis.     

Temozolomide during and after radiation therapy for WHO grade III gliomas: preliminary report of a prospective multicenter study

This prospective study was performed to determine the efficacy, safety, and tolerability of concurrent chemoradiotherapy (CCRT) followed by adjuvant chemotherapy with temozolomide (TMZ) in the treatment of patients with WHO grade III gliomas. Thirty-three adult patients with WHO grade III glioma and aged >17 years were enrolled from three institutions between 2003 and 2008. The median age was 41 years (range, 17?C60 years). The pathological diagnoses were anaplastic astrocytomas in 21 patients and anaplastic oligodendrogliomas in 12 patients. The preoperative Karnofsky performance scale score was >60 for all patients. The patients received fractionated focal irradiation in daily fractions of 2 Gy administered five days per week for six weeks, for a total of 60 Gy, in combination with continuous daily TMZ, followed by six cycles of adjuvant TMZ. The median dose of radiotherapy was 59.4 Gy (range, 28.8?C61.2 Gy) and the duration of CCRT was 7.0 weeks (range, 3.1?C8.3 weeks). A median of 6.2 cycles (range, 2?C12 cycles) of TMZ chemotherapy were performed during the period of adjuvant chemotherapy. The response rate was 61% and the tumor-control rate was 82%. Mean progression-free survival (PFS) was 48.7 months (95% CI, 36.0?C61.4) and the 12, 24, and 36-month PFS was 74%, 60%, and 50%, respectively. Mean overall survival (OS) was 66.4 months (95% CI, 56.4?C76.4) and the 12 and 24-month OS was 97% and 77%, respectively. The extent of surgical resection was a significant prognostic factor for PFS and OS (hazard ratio, 0.24; 95% CI, 0.02?C0.73; and hazard ratio, 0.12; 95% CI, 0.01?C0.88, respectively; P < 0.001). However, there was no significant difference in the PFS and OS of patients regarding loss of heterozygosity in chromosomes 1p and 19q and methylation of O ⁶-methylguanine-DNA methyltransferase promoter, because of the small number of patients available. Only five cases (15%) receiving CCRT with TMZ and three cases (9%) receiving adjuvant chemotherapy had hematological toxicity greater than grade 3. All these patients, however, tolerated the therapy well enough to continue treatment. No opportunistic infections were noted. This protocol for WHO grade III gliomas was relatively safe and tolerable. It showed the possibility of achieving favorable results compared with those of historical controls. A randomized controlled study with a long-term follow-up may be mandatory to evaluate its efficacy.
