Elderly and poor prognosis patients with high grade glioma: hypofractionated radiotherapy.

AIM: To evaluate efficacy of short-course radiotherapy in elderly and/or poor performance status patients with high grade glioma. MATERIALS AND METHODS: Twenty-one patients with high grade astrocytoma were selected in our Institute to receive hypofractionated radiotherapy. We considered two radiotherapy treatment arms: in arm I there were 22 patients treated with 60 Gy in 30 fractions at 5 fractions per week; in arm 2 there were 21 patients who received hypofractionated radiotherapy course of 30 Gy in 10 fractions at 5 fractions per week. RESULTS: In arm1 the median survival time was 8.2 months and the 1 year overall survival was 36%; in arm 2 the estimated median survival was 6.2 months and the 1 year overall survival was 23%. Treatment was without acute toxicity. CONCLUSIONS: In our experience, hypofractionated radiotherapy seems to be a reasonable treatment option for poor prognosis patients with high grade astrocytoma. It is well tolerated and can reduce the overall treatment time without negative effects on survival compared with conventional fractionation.

A phase II study of gemcitabine and tamoxifen in advanced pancreatic cancer.

BACKGROUND: Advanced pancreatic cancer (APC) constitutes a poor-prognosis disease with few and disappointing therapeutic options. In recent years chemotherapy has demonstrated a positive effect on disease-related symptoms with the introduction of a novel pyrimidine analogue, gemcitabine. Moreover there is experimental and clinical evidence that endocrine therapy may play a small but unexplored role in the management of APC. Therefore we performed a phase II study to assess whether the combination of gemcitabine and tamoxifen could be an active and safe schedule for the treatment of APC in terms of response rate and clinical benefits. MATERIALS AND METHODS: Twenty-seven evaluable consecutive patients with locally advanced, unresectable or metastatic adenocarcinoma of the pancreas were treated with gemcitabine (1000 mg/mq given as a short infusion once weekly for 3 consecutive weeks out of every 4 weeks) and tamoxifen (20 mg daily starting the second day after gemcitabine). The treatment was continued until progression or unacceptable toxicity. Evaluation of efficacy included response rate, time to progression, survival and clinical benefit, an integrated measurement of pain parameters, weight and performance status. RESULTS: A partial response was achieved in 11% of patients while 48% experienced stable disease, lasting at least 8 weeks; disease progression was documented in 41% of patients. The median time of progression was 4.5 months; the median survival-time was 8 months and one-year survival was 31%. Clinical benefit was documented in 59% of patients with a median duration of 13 weeks. No gastrointestinal or haematological grade 4 toxicity was observed. In general the treatment showed a satisfactory safety profile and tamoxifen-related toxicity was not documented. CONCLUSION: The combination of gemcitabine and tamoxifen appears to be an innovative therapeutic approach in the management of APC with interesting clinical activity and a good profile of toxicity. This novel schedule of treatment deserves further investigation in large randomized trials to assess if the addition of tamoxifen could improve the therapeutic results of gemcitabine in APC, mostly in term of quality of lfe.

[Chemotherapy in the elderly patient]. / I trattamenti chemioterapici nel paziente anziano.

In the past, the clinical approach in elderly cancer patients was different than in younger ones; the natural history of neoplastic disease and the chemotherapy-related toxicity were the main reasons for this behaviour, and frequently over 65 years patients were excluded from chemotherapeutic treatments and from clinical trials. In the last years, according to clinical data, this approach changed and now there is evidence that also old patients (70-80 ys) can be treated with full dose chemotherapy, on condition that no poor performance status and no severe associated disease are present. Nevertheless, because of the increasing number of cancer patients with advanced age, in future it will be necessary to optimize the antineoplastic treatments individualizing chemotherapy and improving the clinical surveillance in this subset of patients. Moreover it will be strategic to identify optimal schedules of treatment in elderly cancer patients.
