Temozolomide (TMZ) is the first line drug in the care of high grade gliomas. The combined treatment of TMZ plus radiotherapy is more effective in the care of brain gliomas then radiotherapy alone. Aim of this report is a survival comparison, on a long time (>10 years) span, of glioma patients treated with radiotherapy alone and with radiotherapy + TMZ. Materials and Methods. In this report we retrospectively reviewed the outcome of 128 consecutive pts with diagnosis of high grade gliomas referred to our institutions from April 1994 to November 2001. The first 64 pts were treated with RT alone and the other 64 with a combination of RT and adjuvant or concomitant TMZ. Results. Grade 3 (G3) haematological toxicity was recorded in 6 (9%) of 64 pts treated with RT and TMZ. No G4 haematological toxicity was observed. Age, histology, and administration of TMZ were statistically significant prognostic factors associated with 2 years overall survival (OS). PFS was for GBM 9 months, for AA 11. Conclusions. The combination of RT and TMZ improves long term survival in glioma patients. Our results confirm the superiority of the combination on a long time basis.

We report the favorable results of a schedule combining radiotherapy and temozolomide in the treatment of patients with high-grade gliomas. The literature data and above all the findings of the phase III EORTC-NCIC 26981 trial suggest that actually the schedule can be used routinely in clinical practice. Further clinical studies, using temozolomide in combination with other agents, are required.

Invasive urinary tumors are relatively rare and their treatment may cause important changes in urinary, sexual, and social functions. A systematic review of external radiation therapy studies in urinary cancers has been carried out. This synthesis of the literature is based on data from meta-analysis, randomized and prospective trials, and retrospective studies. There are few controlled clinical trials using adjuvant or radical radiotherapy +/- chemotherapy in kidney, ureter, and urethra cancers; there are several reports of muscle-invasive bladder cancer using multimodality treatment: intravesical surgery and neo-adjuvant chemotherapy to radiotherapy or concomitant radiochemotherapy with organ preservation. The conclusions reached for renal cancer are controversial; urethra and ureter cancers data are few and inconclusive; sufficient data now exist in literature to demonstrate that conservative management with organ preservation, for muscle-invasive bladder cancer, is a valid alternative to radical cystectomy, viewed as the gold standard.

The conclusions reached for renal cancer are controversial, and data on cancers of the urethra and ureter are few and inconclusive. Sufficient data now exist in the literature to demonstrate that conservative management with organ preservation is a valuable alternative to radical cystectomy, the traditional gold standard, in invasive bladder cancer.

ObjectiveThis retrospective, multicenter study analyzes the efficacy and safety of stereotactic body radiotherapy in a large cohort of patients with oligometastatic/persistent/recurrent cervical cancer.MethodsA standardized data collection from several radiotherapy centers that treated patients by stereotactic body radiotherapy between March 2006 and February 2021 was set up. Clinical and stereotactic body radiotherapy parameters were collected. Objective response rate was defined as a composite of complete and partial response, while clinical benefit included objective response rate plus stable disease. Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer and Common Terminology Criteria for Adverse Events scales were used to grade toxicities. The primary endpoints were the rate of complete response to stereotactic body radiotherapy, and the 2 year actuarial local control rate on a ‘per lesion’ basis. The secondary end points were progression-free survival and overall survival, as well as toxicity.ResultsA total of 83 patients with oligometastatic/persistent/recurrent cervical cancer bearing 125 lesions treated by stereotactic body radiotherapy at 15 different centers were selected for analysis. Of the sites of metastatic disease, lymph node metastases were most common (55.2%), followed by parenchyma lesions (44.8%). Median total dose was 35 Gy (range 10–60), in five fractions (range 1–10), with a median dose/fraction of 7 Gy (range 4–26). Complete, partial, and stable response were found in 73 (58.4%), 29 (23.2%), and 16 (12.8%) lesions, respectively, reaching 94.4% of the clinical benefit rate. Forty-six (55.4%) patients had a complete response. Patients achieving complete response on a ‘per lesion’ basis experienced a 2 year actuarial local control rate of 89.0% versus 22.1% in lesions not achieving complete response (p<0.001). The 2 year actuarial progression-free survival rate was 42.5% in patients with complete response versus 7.8% in patients with partial response or stable or progressive disease (p=0.001). The 2 year actuarial overall survival rate was 68.9% in patients with complete response versus 44.3% in patients with partial response or stable or progressive disease (p=0.015). Fifteen patients (18.1%) had mild acute toxicity, totaling 29 side events. Late toxicity was documented in four patients (4.8%) totaling seven adverse events.ConclusionOur analysis confirmed the efficacy of stereotactic body radiotherapy in oligometastatic/persistent/recurrent cervical cancer patients. The low toxicity profile encourages the wider use of stereotactic body radiotherapy in this setting.

We studied 67 healthy males aged 20–30 years, 29 of them non-smokers and 38 smokers. In smokers, forced expiratory volume (FEV), 1 s forced expiratory volume (FEV₁) and peak flow (PF) were significantly lower than in non-smokers, while the FEV₁/FEV ratio, flows and mean transit time (MTT) compared well. MTT appeared directly related to age and negatively to FEV₁/FEV, with no difference between the two groups, but MTT was directly related to FEV in non-smokers and negatively in smokers. Multiple regression analysis, MTT=a+b(FEV)+c(age), showed that parameters b and c were significantly different between smokers and non-smokers and, in the former, parameter b was negative. In non-smokers the effects of age and FEV on MTT were roughly the same, but in smokers MTT was influenced above all by age, probably because MTT measured the effects of continued smoking.
