Critical Reviews in Oncology/Hematology | Year: 2011

Metastatic renal cell carcinoma is resistant to conventional treatment with chemotherapy. Recently the use of molecular-targeted therapies with multikinase inhibitors has been recommended as first-choice therapy because they inhibit cell proliferation and tumour angiogenesis. Sorafenib is a well tolerated tyrosine kinase inhibitor that initially demonstrated efficacy in the treatment of patients with metastatic RCC who progressed after immunotherapy. Expanded-access studies in Europe and North America showed the safety and efficacy of sorafenib in special populations such as elderly, renal failure and cerebral metastases, as well as patients with no prior therapy. No cross-resistance has been suggested in non-randomized trials when used in second line treatment after other targeted therapies. Ongoing clinical trials will better define the role of sorafenib in first and second line either as monotherapy or in combination, as well as the best strategies for the sequential use of this drug. © 2011 Elsevier Ireland Ltd.

To perform a comparative study of 500 consecutive (125)I seeds implants for intracapsular prostate carcinoma with two techniques differing in terms of both strand implantation and planning.From 2002 to 2007 we performed 250 implants with fixed stranded seeds (RapidStrand) and a preplanning system and from 2007 to 2010, 250 with real-time and ProLink system. Mean age was 68 and 66, respectively, median PSA (prostate-specific antigen) 7.3 and 7.2, stage T1-T2a in 98% and 94%, and Gleason 6 in 96% and 86%. Low risk cases were 81% and 71%. The prescribed dose was 145 Gy to the prostate volume, or 108 Gy plus EBRT 46 Gy in some intermediate risk cases. Hormonal treatment was given to 42% and 28%.Median follow-up was 48 and 47 months, respectively, 14 patients in the first group and 7 patients in the second developed biochemical failure (BF). Actuarial biochemical relapse-free survival (bRFS) at 5 years increased from 90.2% to 97.2% (low risk from 91.3% to 97.2%, intermediate risk from 84.2% to 97.1%). Biochemical failure was independent of hormone treatment. Rectal complications were G1-2 in 1.2% and 5.2%, respectively. A urinary catheter was necessary in 6.9% and 9.6%, and urethral resection in 1.9% and 4.4%. Genitourinary toxicity was G1-2 in 4.6% and 12%, G3-4 in 1.9% and 4.8%. An assessment of mean D90 in a sample of patients showed that the dosimetry in postoperative planning based on CT improved from a mean D90 of 143 Gy to 157 Gy.The outcome of patients with low risk prostate carcinoma treated with (125)I seed is very good with low complications rate. The real-time approach in our hands achieved a more precise seed implantation, better dosimetry, and a statistically non-significant better biochemical control. We have made this our standard technique.

To assess the relationship between prostate cancer (PC) and the presence of metabolic syndrome and late-onset hypogonadism (LOH) syndrome.A retrospective study was conducted on 686 patients who underwent prostate biopsy. We analysed the demographic variables, clinical data and biopsy results. To diagnose metabolic syndrome, we employed the criteria of the American Heart Association. For the diagnosis of LOH syndrome, we employed the Androgen Deficiency in the Aging Male questionnaire and testosterone levels (TT). We evaluated the relationship between free testosterone (FT) and bioavailable testosterone (BT) on one hand and PC and its aggressiveness on the other, as well as the usefulness of the TT to prostate specific antigen (TT/PSA) ratio in the PC diagnosis.The patients median age was 65 years. Metabolic syndrome is not associated with PC (39.4% vs. 35%; P=.1) but is associated with a PC Gleason score >7 (50.4% vs. 29.44%; P=.002). LOH, low FT and low BT are associated with an increased presence of PC (51% vs. 35%, P=.02; 44.86% vs. 33.33%, P=.03; and 46.46% vs. 33.08%, P=.01, respectively) and with an increased probability of a PC Gleason score >7 (61.54% vs. 37.5%, P=.02; 54.17% vs. 34.12%, P=.02; 54.35% vs. 34.48%, P=.02, respectively). Additionally, the median TT/PSA ratio was significantly lower in patients with positive biopsies (P=.022).Metabolic syndrome was not associated with the probability of having PC but was associated with a PC Gleason score >7. Moreover, LOH syndrome had a higher percentage of PC and a greater presence of PC Gleason scores >7, as did low levels of FT and low levels of BT.

Purpose: To evaluate the results of high-dose-rate (HDR)-interstitial brachytherapy (ISBT) in oral tongue carcinomas. Methods and Materials: Between September 1999 and August 2007, 50 patients were treated for oral tongue carcinoma with HDR-ISBT. The patient's mean age was 58 years. Forty-two patients were in T1-2 stage and 8 patients were in T3 stage; 16 patients were in N+ stage and 34 patients in N0 stage. Exclusive ISBT was given to 17 patients (34%) in T1-2 N0 stage and complementary to external beam radiotherapy (EBRT) to 33 patients (66%). A perioperative technique was performed on 14 patients. The median total dose was 44. Gy when HDR was used alone (4. Gy per fraction) and 18. Gy when complementary to 50. Gy EBRT (3. Gy per fraction). Results: The median followup was 44 months. Actuarial disease-free survival rates at 3 and 5 years were 81% and 74%, respectively. Local failure developed in 7 patients. Actuarial local control (LC) rates were 87% and 79% at 3 and 5 years in T1-2 stage 94.5% and 91% and T3 stage 43% and 43% (with salvage surgery). Exclusive HDR cases showed LC in 100% of the cases, and the combined group (EBRT. +. HDR) showed LC in 80% and 69% of the cases at 3 and 5 years (p=0.044). Soft-tissue necrosis developed in 16% and bone necrosis in 4% of the cases. Conclusions: HDR brachytherapy is an effective method for the treatment of oral tongue carcinoma in low-risk cases. Doses per fraction between 3 and 4. Gy yield LC and complication rates similar to low-dose rate. The perioperative technique promises encouraging results. © 2010 American Brachytherapy Society.

Active surveillance was born as a therapeutic strategy for a well selected group of patients with low risk prostate cancer with the aim to defer or completely avoid the negative impact of secondary effects of curative therapies. Nevertheless, the patient who chooses this treatment does it at the expense of greater anxiety and doubts about the possible progression of the disease. The main psychological features influencing the quality of life of these patients are, on one hand anxiety, due to the uncertainty and fear to disease progression, and on the other hand, the difficult decision making process. Among the factors that seem to influence the election are: urologist's recommendation, effects on urinary function, age and impact of the therapy on sexual func tion. In the timorous journey walked, it is recommended to apply psycho-educational programs, with the objective of increasing the perceived control and adaptive confrontation. We propose an intervention with 4 group sessions, the objectives of which would be first to improve the decision making process and diminish the fear to progression and, second to reinforce the information already given at the time of diagnosis and increase the sensation of control, e.g promoting healthy habits.

Purpose: To compare the use of high-dose-rate (HDR) brachytherapy (BT) in patients with lip carcinoma with a former series previously treated with low-dose-rate (LDR) BT. Methods and Materials: Ninety-nine patients treated with LDR-BT were compared with 104 patients treated with HDR-BT. Distribution by stage was 53.5% T1, 15.1% T2, 3.1% T3, and 28.3% T4 for LDR and 52.9% T1, 32.7% T2, 0% T3, and 14.4% T4 for HDR. Some cases with positive or close margins received BT after surgery (34.3% with LDR vs. 16.3% with HDR). Parallel metallic needles were used in 100% of HDR cases and in 76% of LDR cases. Most HDR patients were treated with HDR-BT to a dose of 4.5-5Gy per fraction prescribed to a 90% isodose, in nine fractions delivered twice daily for 5 days. Results: Median followup was 63 months for LDR-BT and 51 months for HDR-BT. Overall local control for LDR- vs. HDR-BT was 94.9% vs. 95.2%; and 100% vs. 100%, 86.6% vs. 94.1%, and 89.3% vs. 80%, for T1, T2, and T4 stage tumors, respectively. Disease-free survival for LDR vs. HDR was 95.9% vs. 94.2%. Soft tissue necrosis, bone necrosis, and fair-bad cosmesis for LDR vs. HDR was 15.1% vs. 0%, 1% vs. 0%, and 11.1% vs. 0%, respectively. Conclusions: Treatment with HDR-BT using rigid needles is a simple technique that provides good long-term results with minimal complications. LDR- and HDR-BT are regarded as equally effective in local control and disease-free survival, but fewer complications arise when using HDR-BT. © 2013 American Brachytherapy Society.

In the era of evidence-based medicine, one of the most important skills a radiologist should have is the ability to analyze the diagnostic literature critically. This tutorial aims to present guidelines for determining whether primary diagnostic articles are valid for clinical practice. The following elements should be evaluated: whether the study can be applied to clinical practice, whether the technique was compared to the reference test, whether an appropriate spectrum of patients was included, whether expectation bias and verification bias were limited, the reproducibility of the study, the practical consequences of the study, the confidence intervals for the parameters analyzed, the normal range for continuous variables, and the placement of the test in the context of other diagnostic tests. We use elementary practical examples to illustrate how to select and interpret the literature on diagnostic imaging and specific references to provide more details. © 2014 SERAM.

In screening programs, overdiagnosis is defined as the detection of a disease that would have gone undetected without screening when that disease would not have resulted in morbimortality and was treated unnecessarily. Overdiagnosis is a bias inherent in screening and an undesired effect of secondary prevention and improved sensitivity of diagnostic techniques. It is difficult to discriminate a priori between clinically relevant diagnoses and those in which treatment is unnecessary. To minimize the effects of overdiagnosis, screening should be done in patients at risk.

To analyze the results obtained after treatment of early stage (T1-T2) squamous cell carcinoma of the lip with high dose rate brachytherapy and evaluate the efficacy of this treatment in both local and regional control.Retrospective analysis of the treatments performed at our department from March 1999 to March 2013 with high dose rate brachytherapy with rigid needles. We included 68 patients, 63 men and 5 women; 37 patients (54.4%) presented a T1 tumour, less than or equal to 2cm, while the other 31 (45.6%) were classified as T2. Median total dose was 45Gy, with a median dose per fraction of 5Gy x 9 fractions twice a day for 5 days.With a mean follow-up of 56.4 months, local control was 96.9%. Stratifying by tumour size, local control of T1 cases was 100%, while T2 achieved 93.2% (2 local recurrences). Regional control at 5 years was 93.8% for T1, and 80.8% for T2. In 11 cases with elective cervical treatment, no regional failure happened. As for toxicity, no patient presented soft tissue, or bone, necrosis. All patients achieved good or excellent cosmetic and functional results.High dose rate brachytherapy allows effective, safe treatments for squamous cell carcinoma of the lip, with good aesthetic and functional results. It can be considered a valid alternative for surgery in early stage tumours.

Lung transplantation (LT) has been considered an alternative therapeutic approach in terminal patients. However, this process in COPD is not controversy-free. This paper aimed to analyze 30-day mortality (PM) patterns and their risk factors in COPD patients undergoing LT.A retrospective cohort with 107 COPD patients, transplanted at the University La Fe Valencia, Spain, treated from January 1991 to December 2008. Demographics values, degree of dyspnoea, diagnosis, BODE index, single versus bilateral LT, cardio-pulmonary bypass, donor age, steroid dependence, presence of bronchiectasis, retrograde perfusion, transfusion of blood products, and PaO2/FiO2 were analyzed. Continuous variables were expressed as meanSD and categorical variables as absolute frequency and percentage. A Cox regression model was used for multivariate analysis.Ninety-four men and 13 women of a mean age of 52.588.05 years were transplanted. Of all patients, 75% obtained a BODE score above 7. There were 76 bilateral LT. PM was established at 14%. Main causes of death were infection (53.3%) and surgical complications (33.3%). Presence of bronchiectasis and chronic use of corticosteroids, donor/recipient difference in size and presence of fat in retrograde perfusion fluid were important risk factors for PM. Moreover, PaO2/FiO2 ratio at 6h was a protective factor for the event, thus a higher ratio value, lowered the risk of PM.LT is a procedure with a high PM rate. Use of corticosteroids, the presence of bronchiectasis and fat emboli in the retrograde reperfusion, and PaO2/FiO2 significantly determine PM.
