Radiotherapy with concurrent or sequential temozolomide in elderly patients with glioblastoma multiforme.

OBJECTIVE: The objective of this article was to evaluate therapeutic outcomes of elderly patients with glioblastoma multiforme (GBM) treated by surgery followed by combined modality therapy and compare achievable outcomes to those of a younger age population. METHODS AND MATERIALS: Seventy-eight adult patients with histologically confirmed grade IV astrocytoma were treated at King Hussein Cancer Center (Amman, Jordan) between September 2004 and December 2008. Records were retrospectively reviewed and included 55 males and 23 females between 19 and 78 years of age (median age 50 years). This case series included 20 patients aged 60 years or older. All patients underwent craniotomy followed radiotherapy and concurrent or sequential temozolomide. The follow-up ranged from 1 to 56 months (median 9.4 months). RESULTS: The median survival for the whole cohort was 13.8 months. The median survival for patients less than 60 years was 14.3 months and for patients 60 years or older was 12.3 months (P = 0.19). Among elderly patients, radical surgical resection (P = 0.002), concurrent delivery of chemoradiation (0.041) and radiotherapy dose ≥ 5400 cGy (P = 0.0001) conferred statistically significant improvements in overall survival. CONCLUSION: Management of GBM in elderly patients should include maximal surgical resection followed by radiotherapy and temozolomide whenever medically feasible. Outcomes comparable to those obtained in younger age groups can be expected. Our results indicate that concurrent chemoradiation is superior to sequential chemoradiation in these patients.

Management strategies for locoregional recurrence in early-stage gastric cancer: retrospective analysis and comprehensive literature review.

OBJECTIVE: To present a comprehensive account and literature review addressing the anatomical distribution, natural history, and management strategies for locoregional recurrence in early-stage gastric cancer (EGC). PATIENTS AND METHODS: Retrospective chart review of patients presenting with EGC recurrence at King Hussein Cancer Center (Amman, Jordan) between July 2006 and May 2009. A literature review of publications addressing recurrence following surgery for EGC was undertaken via a systematic search of PUBMED database and National Comprehensive Cancer Network (NCCN) guideline updates. RESULTS: Seventeen patients presented with EGC, three of whom (17.6%) were pathologically staged as T2N1 [1/33 lymph nodes (LNs)], T1N0, and T1N0 were afflicted by recurrence following R0 partial gastrectomy. Literature review yielded 18 studies specifically addressing recurrence in EGC. Several management strategies have been proposed for isolated recurrence following gastrectomy in EGC. NCCN clinical practice guideline updates do not take into consideration whether the recurrence is isolated or widespread and whether the initial stage is early or advanced. CONCLUSIONS: While acknowledging the limitations of this study, including the small sample size and the short follow-up period, it appears clear that oncologic treatment is possible for EGC recurrence, particularly, in patients with isolated relapse. Guideline updates should differentiate between management strategies suitable for recurrence occurring in early versus advanced initial cancer stage.

The challenges of managing glioblastoma multiforme in developing countries: a trade-off between cost and quality of care.

BACKGROUND AND OBJECTIVES: The management of glioblastoma multiforme (GBM) in developing countries is hindered by the paucity of clear protocols due in part to growing economic constraints and the lack of availability of expensive chemotherapeutic agents. We evaluated the deliverable treatment protocols and achievable outcomes for patients with GBM in a low-income country prior and subsequent to the worldwide adoption of temozolomide. DESIGN AND SETTING: Retrospective case series. PATIENTS AND METHODS: Charts of consecutive patients with a pathologic diagnosis of high-grade glioma diagnosed between January 2003 and December 2008 were retrospectively reviewed. RESULTS: We identified 146 adult patients, including 105 males and 41 females between 19 and 81 years of age (median age, 51 years), with histologically confirmed high-grade glioma. All patients underwent craniotomy. Eighty-two patients were treated with radiotherapy and temozolomide, of whom 42 patients received temozolomide concurrent with radiation followed by adjuvant temozolomide; 40 patients received irradiation followed sequentially by 6 cycles of temozolomide. In 40 patients irradiation was utilized as a single modality treatment adjuvant to surgery. The follow-up ranged from 1 to 56 months (median, 9.4 months). The median survival for the whole cohort was 10.2 months. The median survival for the radiotherapy-alone group was 5.3 months and for combined radiotherapy/temozolomide was 14.8 months. Survival was similar in both concurrent and sequential groups. Temozolomide conferred a statistically significant survival benefit of 9 months compared with standard therapeutic modalities. CONCLUSIONS: The results compare favorably to those reported in developed nations. Current management of GBM in developing countries should include maximal surgical resection followed by radiotherapy/temozolomide whenever medically and/or financially feasible. Outcomes comparable to those obtained within the context of randomized trials can be expected in low-income settings if healthcare delivery is carefully planned. Our results indicate that concurrent and sequential regimens are equally effective in these patients.
