High-risk clinical stage I nonseminomatous germ cell tumors: the case for chemotherapy

Testis cancer is the most frequent solid malignancy in young men. The majority of patients present with clinical stage I disease and about 50% of them are nonseminomatous germ cell tumors. In this initial stage of disease there is a subgroup of patients at high risk with a likelihood of more than 50% for relapse. Treatment options for these patients include: retroperitoneal lymph node dissection (RPLND), albeit 6-10% of patients will relapse outside the field of RPLND, active surveillance with even higher relapse rates and adjuvant chemotherapy. As most of these patients have the chance to become long-term survivors, avoidance of long-term side effects is of utmost importance. This review provides information on the potential of chemotherapy to achieve a higher chance of cure for patients with high-risk clinical stage I disease than its therapeutic alternatives and addresses toxicity and dose dependency.

Complications following radical cystectomy for bladder cancer in the elderly

CONTEXT: The incidence of bladder cancer increases with advancing age. Considering the increasing life expectancy and the increasing proportion of elderly people in the general population, radical cystectomy will be considered for a growing number of elderly patients who suffer from muscle-invasive or recurrent bladder cancer. OBJECTIVE: This article reviews contemporary complication and mortality rates after radical cystectomy in elderly patients and the relationship between age and short-term outcome after this procedure. EVIDENCE ACQUISITION: A literature review was performed using the PubMed database with combinations of the following keywords cystectomy, elderly, complications, and comorbidity. English-language articles published in the year 2000 or later were reviewed. Papers were included in this review if the authors investigated any relationship between age and complication rates with radical cystectomy for bladder cancer or if they reported complication rates stratified by age groups. EVIDENCE SYNTHESIS: Perioperative morbidity and mortality are increased and continence rates after orthotopic urinary diversion are impaired in elderly patients undergoing radical cystectomy. Complications are frequent in this population, particularly when an extended postoperative period (90 d instead of 30 d) is considered. CONCLUSIONS: Although age alone does not preclude radical cystectomy for muscle-invasive or recurrent bladder cancer or for certain types of urinary diversion, careful surveillance is required, even after the first 30 d after surgery. Excellent perioperative management may contribute to the prevention of morbidity and mortality of radical cystectomy, supplementary to the skills of the surgeon, and is probably a reason for the better perioperative results obtained in high-volume centers.

Effect of urinary tract infection on reservoir function in patients with ileal bladder substitute

PURPOSE: We determined the functional consequences of urinary tract infection in patients with an ileal bladder substitute in terms of urinary continence, post-void residual and urinary retention. MATERIALS AND METHODS: A total of 48 patients with culture documented urinary tract infection (single organism, 10(5) or greater cfu) were retrospectively evaluated before, during and after the infection for changes in continence, post-void residual and urinary retention as well as for resolution of symptomatology after appropriate antibiotic therapy. RESULTS: Of the 48 patients 40 had a single infection while the remaining 8 had multiple urinary tract infection episodes. During daytime 27 of the 44 patients with previously good daytime continence experienced deterioration in their baseline voiding status while infected. Of the 40 patients who were previously continent at night 20 had incontinence while infected. There were 15 patients with documented post-void residual and urinary retention developed in 4 during the urinary tract infection. All patients returned to baseline continence status and reservoir function after appropriate antibiotic treatment based on objective and subjective assessments. CONCLUSIONS: Urinary tract infection may cause urinary incontinence in patients with ileal bladder substitutes. Therefore, when there are complaints of de novo urinary incontinence, a finding of post-void residual or an acute presentation of urinary retention, a urinary tract infection should be excluded. When the urinary tract infection is appropriately treated urinary continence and reservoir function return to their baseline status.

The impact of lymphadenectomy and lymph node metastasis on the outcomes of radical cystectomy for bladder cancer

CONTEXT: The presence of lymph node metastases and the extent of lymphadenectomy have both been shown to influence the outcome of patients with muscle-invasive bladder cancer. OBJECTIVE: Current standards for detection of lymph node metastases, lymph-node mapping studies, histopathologic techniques, and risk factors in relation to lymph node involvement are discussed. The impact of lymph node metastases and the extent of lymphadenectomy on the outcome of patients treated with radical cystectomy are analyzed. EVIDENCE ACQUISITION: A systematic literature review of bladder cancer and lymph nodes was performed searching the electronic databases Pubmed/Medline, Cochrane, and Embase. Articles were selected based on title, abstract, study format, and content by a consensus of all participating authors. EVIDENCE SYNTHESIS: Lymph node status is highly consequential in bladder cancer patients because the presence of lymph node metastases is predictive of poor outcome. Knowledge of primary landing sites of lymph node metastases is important for optimum therapeutic management. Accurate pathologic work-ups of resected lymph node tissue are mandatory. Molecular markers could potentially guide therapeutic decisions in the future because they may enable the detection of micrometastatic disease. In current series, radical cystectomy with an extended lymphadenectomy seems to provide a clinically meaningful therapeutic benefit compared with a limited approach. However, the anatomic boundaries of lymph node dissection are still under debate. Therefore, large prospective multicenter trials are needed to validate the influence of extended lymph node dissection on disease-specific survival. CONCLUSIONS: An extended pelvic lymph node dissection (encompassing the external iliac vessels, the obturator fossa, the lateral and medial aspects of the internal iliac vessels, and at least the distal half of the common iliac vessels together with its bifurcation) can be curative in patients with metastasis or micrometastasis to a few nodes. Therefore, the procedure may be offered to all patients undergoing radical cystectomy for invasive bladder cancer.

Long-term follow up (37-69 years) of patients with bladder exstrophy treated with ureterosigmoidostomy: uro-nephrological outcome

OBJECTIVE: To describe the urological and nephrological long-term outcome of patients born with classical bladder exstrophy treated with bilateral ureterosigmoidostomies in early childhood. PATIENTS AND METHOD: Out of 42 patients born with bladder exstrophy in Switzerland between 1937 and 1968, 25 participated in this study; seven had died, seven were lost to follow up and three refused consent. Assessment included chart review, clinical examination, and assessment of renal function and morphology. RESULTS: After a follow-up period of 37-69 years ((mean 50 years), 13 of the 25 participants (52%) had their ureterosigmoidostomy still in place. All others had different forms of urinary diversions. Fifteen (60%) patients had normal renal function or mild chronic kidney disease as assessed by estimated glomerular filtration rate. Three patients were on renal replacement therapy. MRI (n=16) showed 10 morphologically normal kidneys. One patient suffered from adenocarcinoma of the colon, five had benign colonic polyps, one urethral papillary carcinoma and 18 no evidence of tumor. CONCLUSION: The majority of our patients have normal or mildly impaired renal function and a well functioning ureterosigmoidostomy. This is remarkable, given the fact that ureterosigmoidostomies are considered to be refluxing high-pressure reservoirs at risk of renal injury and malignancy.

No evidence of osteopenia 5 to 8 years after ileal orthotopic bladder substitution

The use of bowel segments as bladder substitutes may result in chronic, impaired vitamin D and calcium metabolism, and ultimately in bone demineralization.

Patients with oral tumors. Part 2: Quality of life after treatment with resection prostheses. Resection prosthetics: evaluation of quality of life

In the present study, the oral health-related quality of life of 18 patients (13 men and 5 women) was evaluated using validated questionnaires as proposed by the European Organization of Research and Treatment of Cancer (EORTC). The patients belonged to a cohort of 48 patients, whose prosthetic treatment was performed during the years 2004-2007. In the course of tumor resection, 12 patients underwent graft surgery and 14 patients radiotherapy. One patient required a nasal epithesis since resection of the nose became necessary. Five patients underwent a full block resection of the mandible, and tumor resection in 3 patients resulted in a large oronasal communication. Prosthetic rehabilitation was performed in all patients, and the follow-up period with regular care covered a minimum of 3 years. Eleven patients received dental implants for better support and retention of the prostheses. In spite of compromised oral conditions, functional restrictions, and some difficulties with the prostheses, the answers to the questionnaire were quite positive. The majority judged their general health as good or even excellent. The subjective perception of the patients may contradict the objective view by the dentist. In fact, the individual patient's history and experience provide a better understanding of the impact of oral tumors on daily life. The overall assessment identified 4 items that were perceived as major problems by all patients: swallowing solid food, dry mouth, limited mouth opening, and appearance. Prosthetic rehabilitation has only a limited influence on such problems.

Patients with oral tumors. Part 1: Prosthetic rehabilitation following tumor resection. Resection prosthetics: surgery, implants and prosthetic treatment

The present study reports on the surgical and prosthodontic rehabilitation of 46 patients, 31 male and 15 female, after resection of oral tumors. The treatment was carried out from 2004 to 2007 at the Department of Prosthodontics, University of Bern, with a follow-up time of 3 to 6 years. The average age at diagnosis was 54 years. 76% of all tumors were squamous cell carcinoma, followed by adenocarcinoma. Resection of the tumors including soft and/or hard tissues was performed in all patients. 80% of them additionally underwent radiotherapy and 40% chemotherapy. A full block resection of the mandible was perfomed in 23 patients, and in 10 patients, the tumor resection resulted in an oronasal communication. 29 patients underwent grafting procedures, mostly consisting of a free fibula flap transplant. To enhance the prosthetic treatment outcome and improve the prosthesis stability, a total of 114 implants were placed. However, 14 implants were not loaded because they failed during the healing period or the patient could not complete the final treatment with the prostheses. The survival rate of the implants reached 84.2% after 4 to 5 years. Many patients were only partially dentate before the tumors were detected, and further teeth had to be extracted in the course of the tumor therapy. Altogether, 31 jaws became or remained edentulous. Implants provide stability and may facilitate the adaptation to the denture, but their survival rate was compromised. Mostly, patients were fitted with removable prostheses with obturators in the maxilla and implant-supported complete dentures with bars in the mandible. Although sequelae of tumor resection are similar in many patients, the individual intermaxillary relations, facial morphology and functional capacity vary significantly. Thus, individual management is required for prosthetic rehabilitation.
