OBJECTIVETo study the clinical features and proper treatment of 38 elderly patients with early double primary cancers.

METHODSThirty-eight elderly patients with early double primary cancers treated from January 1980 to March 2003 were retrospectively reviewed for involved organs, treatment and prognosis.

RESULTSDigestive tract was the most frequently involved, followed by urogenital system and lung. Long-term results of endoscopic mucosal resection (EMR), operation and radiotherapy were superior to other methods. The prognosis of gastrointestinal carcinoma was better than that of prostate carcinoma and hematopoietic system. The operation rate decreased with increasing age. The 5-year survival rates of EMR, operation and radiotherapy were 85.7%, 71.1% and 75.0%, respectively. The medium survival time was 120 months in first cancer and 39 months in the second primary cancer. The 5-year survival rates of the first cancer and second primary cancer were 88.6% and 53.8%.

CONCLUSIONYearly follow-up for elderly patients with endoscopy, beta ultrasonic scan and X-ray contribute to finding of early double primary cancers. Operation is the best treatment of early double primary cancers. Endoscopic mucosal resection is especially suitable for old patients with digestive tract and bladder cancer.

PURPOSE: To evaluate the oncologic outcomes between adjuvant radiotherapy (ART) and salvage radiotherapy (SRT) in patients with locally advanced prostate cancer or with adverse pathologic factors including positive surgical margin and high Gleason score. MATERIALS AND METHODS: We searched the literature published from January 2000 until December 2014 at MEDLINE, PubMed, Web of Science, Embase, ProQuest, and Cochrane Library. To be specific, included were studies comparing ART and SRT settings if they followed up oncologic outcomes more than 5 years. RESULTS: Overall, 3 retrospective, nonrandomized, observational studies, 1 matched control analysis, and 3 prospective randomized controlled studies met our inclusion criteria including a total of 2,380 patients (1,192 ART vs. 1,188 SRT). Higher favorable results were found in ART than in SRT was seen in the 5-year and 10-year biochemical recurrence (BCR)-free survival (risk ratio [RR], 0.61 and 0.70; 95% confidence interval [CI], 0.54-0.69 and 0.63-0.76). ART had a significantly higher 5-year progression-free survival rate than that in SRT (RR, 0.64; 95% CI, 0.51-0.80), but this was not the same for the 10-year progression-free survival rate (RR, 0.88; 95% CI, 0.72-1.08). There was no significant difference for the 5-year and 10-year overall survival rates between ART and SRT (RR, 0.80 and 0.94; 95% CI, 0.59-1.07 and 0.80-1.11). CONCLUSIONS: ART showed favorable results in BCR-free survival during the 5-year follow-up period. However, the 10-year progression-free survival and overall survival did not show any difference between ART and SRT.

Recently, the D'Amico classification system is widely used for the risk stratification of prostate cancer (PCa) , although no consensus has been reached for the definition of high-risk PCa. This system defines high-risk PCa as a prostate-specific antigen (PSA) level > 20 ng/ml, a Gleason score of 8-10, or a clinical stage ≥ T2c. Because high-risk PCa is prone to recurrence and metastasis after treatment, a proper initial therapy plays a crucial role. Currently, radical prostatectomy and radiation therapy are considered to be two most important options for the initial treatment of high-risk PCa although it remains controversial which is better.

The aim of the present study was to evaluate the efficacy and toxicity of stereotactic body radiation therapy (SBRT) for low- to intermediate-risk prostate adenocarcinoma. Thirty-nine patients were retrospectively reviewed. The SBRT was delivered using the CyberKnife with the fiducial tracking method combined with In-tempo imaging. The gross target volume, which included the prostate only, was delineated on the fused CT/MRI scans. The prescription dose was delivered every other day as 5 fractions of 7.5 Gy. Venous blood was obtained before and after SBRT to assess the prostate-specific antigen (PSA) level. Toxicity was evaluated using the CTCAE, v4.03. The median follow-up time was 30.0 months. The median initial PSA level was 7.7 ng/mL. PSA levels decreased in all patients treated with SBRT, and after 5 months, the median PSA was less than 2 ng/mL. The rate of overall 3-yr actuarial biochemical failure free survival was 93.9%. Acute side effects were generally comparable with those of previous studies. The PSA change and toxicity after SBRT for low- to intermediate-risk prostate adenocarcinoma indicates favorable biochemical responses and tolerable levels of toxicity. Additionally short course treatment may produce cost benefit and convenience to patients.

The incidence and mortality of prostate cancer in China are increasing year by year. The review is focused on current hot prospects of prostate cancer. The value of serum prostate specific antigen (PSA) screening is still controversial, and PSA screening in high-risk groups is recommended for early diagnosis of prostate cancer. Prostate biopsy including transrectal approach and perineal approach, and two methods have both advantages and disadvantages. There is significant correlation between testosterone levels and the prognosis of prostate cancer, and the monitoring of testosterone level contributes to the treatment. The main complications of radical resection of prostate cancer is urinary incontinence and erectile dysfunction, three-dimensional laparoscopic and robot assisted laparoscopic techniques have obvious advantages in radical operation. Brachytherapy is another option for radical treatment, with relaxed age limit, low incidence of erectile dysfunction, urinary incontinence and reliable curative effect. The diagnosis and treatment of new technologies include such as MRI dynamic enhancement scan, ¹⁸F-fluoroethyl PET/CT, ultrasound contrast technology, prostate cancer immunotherapy, et al.

Health-related quality-of-life (HRQOL) after a radical prostatectomy (RP) or external beam radiation therapy (EBRT) has not been studied in conjunction with oncological outcomes in relation to disease risk stratification. Moreover, the long-term outcomes of these treatment approaches have not been studied. We retrospectively analyzed oncological outcomes between consecutive patients receiving RP (n=86) and EBRT (n=76) for localized prostate cancer. HRQOL and functional outcomes could be assessed in 62 RP (79%) and 54 EBRT (79%) patients over a 3-year follow-up period (median: 41 months) using the Medical Outcomes Study Short Form-36 (SF-36) and the University of California Los Angeles Prostate Cancer Index (UCLA PCI). The 5-year biochemical progression-free survival did not differ between the RP and EBRT groups for low-risk (74.6% vs. 75.0%, P=0.931) and intermediate-risk (61.3% vs. 71.1%, P=0.691) patients. For high-risk patients, progression-free survival was lower in the RP group (45.1%) than in the EBRT group (79.7%) (P=0.002). The general HRQOL was comparable between the two groups. Regarding functional outcomes, the RP group reported lower scores on urinary function and less urinary bother and sexual bother than the EBRT group (P<0.001, P<0.05 and P<0.001, respectively). With risk stratification, the low- and intermediate-risk patients in the RP group reported poorer urinary function than patients in the EBRT group (P<0.001 for each). The sexual function of the high-risk patients in the EBRT group was better than that of the same risk RP patients (P<0.001). Biochemical recurrence was not associated with the UCLA PCI score in either group. In conclusion, low- to intermediate-risk patients treated with an RP may report relatively decreased urinary function during long-term follow-up. The patient's HRQOL after treatment did not depend on biochemical recurrence.

Skeletal metastases result in significant morbidity and mortality. This is particularly true of cancers with a strong predilection for the bone, such as breast, prostate, and lung cancers. There is currently no reliable cure for skeletal metastasis, and palliative therapy options are limited. The Wnt signaling pathway has been found to play an integral role in the process of skeletal metastasis and may be an important clinical target. Several experimental models of skeletal metastasis have been used to find new biomarkers and test new treatments. In this review, we discuss pathologic process of bone metastasis, the roles of the Wnt signaling, and the available experimental models and treatments.

With the onset of a metabolic syndrome epidemic and the increasing life expectancy, erectile dysfunction (ED) has become a more common condition. As incidence and prevalence increase, the medical field is focused on providing more appropriate therapies. It is common knowledge that ED is a chronic condition that is also associated with a myriad of other disorders. Conditions such as aging, diabetes mellitus, hypertension, obesity, prostatic hypertrophy, and prostate cancer, among others, have a direct implication on the onset and progression of ED. Characterization and recognition of risk factors may help clinicians recognize and properly treat patients suffering from ED. One of the most reliable treatments for ED is penile prosthetic surgery. Since the introduction of the penile prosthesis (PP) in the early seventies, this surgical procedure has improved the lives of thousands of men, with reliable and satisfactory results. The aim of this review article is to characterize the epidemiology of men undergoing penile prosthetic surgery, with a discussion about the most common conditions involved in the development of ED, and that ultimately drive patients into electing to undergo PP placement.
