RESUMO

OBJECTIVE: To evaluate patients' and partners' satisfaction with a prostate cancer survivorship program embedded in urologic-oncologic care. As a part of quality improvement activity, we developed a patient and partner-centered, biopsychosocial support program for men and partners coping with the urinary and sexual side-effects of surgical treatment for prostate cancer. The program became a part of usual care for all prostate cancer patients. METHODS: Patients who saw both an advanced practice provider and a sex therapist between August 1, 2018 and July 31, 2019 were eligible. Surveys packets were sent to 146 patients with surveys included for partners (N = 292). We used descriptive statistics to characterize participant responses. RESULTS: Responses were received from 88 patients and 70 partners (56% response rate for the group). Patients and partners reported very high or fairly high satisfaction with the rehabilitation activities of the program (86-97% and 90%-100%, respectively); 91% of patients and 84% of partners thought having pre-operative education and post-operative rehabilitation was a good or fairly good idea; 83% of patients and 79% of partners would very much or somewhat recommend the program to a friend who was considering surgical treatment for prostate cancer. CONCLUSION: Embedding a patient and partner-centered prostate cancer survivorship support program in oncologic care can positively impact patients' and partners' engagement in and satisfaction with post-operative rehabilitation.

RESUMO

BACKGROUND: Recent recognition that a predisposition to prostate cancer can be inherited has led to a search for specific genes associated with the disease. Through a study of families with three or more affected first-degree relatives, a region on the long arm of chromosome 1 (i.e., 1q24-25) has been tentatively identified as containing a gene, HPC1, involved in the development of hereditary prostate cancer. Confirmation of this finding is needed, however, before attempts are made to isolate and characterize the putative HPC1 gene. PURPOSE: To confirm that chromosome 1q24-25 contains a gene relevant to hereditary prostate cancer, we analyzed an independent set of families, each with two or more affected individuals. METHODS: Fifty-nine unrelated families were selected for analysis on the sole criterion that more than one living family member was affected by prostate cancer. DNA samples were subsequently isolated from 130 individuals with the disease. These samples were genotyped at six polymorphic marker sequences (D1S215, D1S2883, D1S466, D1S158, D1S518, and D1S2757) covering the chromosomal region proposed to contain HPC1. The resulting data were analyzed by nonparametric multipoint linkage (NPL) methods, yielding NPL Z scores and corresponding one-sided P values. RESULTS: When the entire set of 59 families was considered, the occurrence of prostate cancer (and, presumably, the HPC1 gene) was most tightly linked to marker D1S466 (NPL Z score = 1.58; P = .0574). Analysis of the 20 families (51 affected individuals) fulfilling one or more of the proposed clinical criteria for hereditary prostate cancer (i.e., three or more affected individuals within one nuclear family; affected individuals in three successive generations [maternal or paternal lineage]; and/or clustering of two or more individuals affected before the age of 55 years) revealed more convincing evidence of disease linkage to chromosome 1q24-25 (maximum NPL Z score [at marker D1S466] = 1.72; P = .0451). The 39 families (79 affected individuals) that did not meet the clinical criteria for hereditary prostate cancer exhibited no significant evidence of disease linkage to DNA sequences at chromosome 1q24-25 (maximum NPL Z score [at marker D1S466] = 0.809; P = .208). The six African-American families in our study contributed disproportionately to the observation of linkage, with a maximum NPL Z score at marker D1S158 of 1.39 (P = .0848) for these families. CONCLUSIONS AND IMPLICATIONS: Our data confirm that chromosome 1q24-25 is likely to contain a prostate cancer susceptibility gene. Future efforts at positional cloning of the HPC1 gene should focus on families who meet the proposed clinical criteria for hereditary prostate cancer.

RESUMO

BACKGROUND: We used data from the Michigan Urological Surgery Improvement Collaborative (MUSIC) to investigate the use of adjuvant and salvage radiotherapy (ART, SRT) among patients with high-risk pathology following radical prostatectomy (RP). METHODS: For patients with pT3a disease or higher and/or positive surgical margins, we examined post-RP radiotherapy administration across MUSIC practices. We excluded patients with <6 months follow-up, and those that failed to achieve a postoperative PSA nadir ⩽0.1. ART was defined as radiation administered within 1 year post RP, with all post-nadir PSA levels <0.1 ng ml(-1). Radiation administered >1 year post RP and/or after a post-nadir PSA ⩾0.1 ng ml(-1) was defined as SRT. We used claims data to externally validate radiation administration. RESULTS: Among 2337 patients undergoing RP, 668 (28.6%) were at high risk of recurrence. Of these, 52 (7.8%) received ART and 56 (8.4%) underwent SRT. Patients receiving ART were younger (P=0.027), more likely to have a greater surgical Gleason sum (P=0.009), higher pathologic stage (P<0.001) and received treatment at the smallest and largest size practices (P=0.011). Utilization of both ART and SRT varied widely across MUSIC practices (P<0.001 and P=0.046, respectively), but practice-level rates of ART and SRT administration were positively correlated (P=0.003) with lower ART practices also utilizing SRT less frequently. Of the 88 patients not receiving ART and experiencing a PSA recurrence ⩾0.2 ng ml(-1), 38 (43.2%) progressed to a PSA ⩾0.5 ng ml(-1) and 20 (22.7%) to a PSA ⩾1.0 ng ml(-1) without receiving prior SRT. There was excellent concordance between registry and claims data κ=0.98 (95% CI: 0.94-1.0). CONCLUSIONS: Utilization of ART and SRT is infrequent and variable across urology practices in Michigan. Although early SRT is an alternative to ART, it is not consistently utilized in the setting of post-RP biochemical recurrence. Quality improvement initiatives focused on current postoperative radiotherapy administration guidelines may yield significant gains for this high-risk population.

RESUMO

The present study tested the predictive validity at 3 years of age of a screening device for the early identification of later cognitive delay. The screening device, administered between 3 and 7 months of age, is based on the infant's differential fixation "to novel" over previously shown pictures. The sample was composed of 62 infants suspected to be at risk for later mental retardation. The prevalence of delayed cognitive development (IQ less than or equal to 70) at 3 years of age was 13%. Novelty preference scores correctly identified six of eight (75%) of the delayed children. The test identified 49 of 54 (91%) of the normal children. Validity for predicting cognitive delay was 55%. Validity for the prediction of normality was 96%. The screening device proved to be equally sensitive, specific, and valid when the sample was divided into infants born at term or born preterm. The results of the present study and of a previous study indicate that detection of cognitive delay based on early novelty preferences is as easily accomplished for infants who will later be mildly delayed (IQ scores 60 to 70) as it is for those who will later be severely delayed (IQ scores less than or equal to 50). Moreover, such results are in contrast to those obtained with conventional tests tapping sensorimotor development.

RESUMO

We studied the expression of cytokeratin (CK)-7 and CK-20 in prostate adenocarcinoma and urothelial carcinoma and evaluated their usefulness for distinguishing high-grade forms of these tumors. We examined prostate adenocarcinoma in 59 radical prostatectomy specimens and in 10 autopsy specimens showing metastatic disease, and urothelial carcinoma of the bladder in 28 cystectomy specimens. Immunohistochemical staining for CK-7, CK-20, and prostate-specific antigen (PSA) was performed on paraffin sections. For prostate adenocarcinoma, 5 cases had only CK-7 positivity, 5 had only CK-20 focal positivity, 1 stained for both markers, and 48 were negative for both. PSA was positive in all but 1 poorly differentiated prostatic carcinoma. In the autopsy cases, PSA was expressed in the prostate and the metastatic tumors in most cases; few cases were focally positive for CK-7 or CK-20, but none was positive for both markers. For the urothelial tumors, CK-7 was the sole positive marker in 6 cases, and CK-20 in 1 case; 17 cases were positive for both, and 4 were negative for both. All urothelial carcinomas were PSA negative. Although PSA is useful for differentiating prostatic from urothelial carcinoma, CK-7 and CK-20 are helpful when both are positive, supporting the diagnosis of urothelial carcinoma. However, if only 1 marker is positive or both are negative, these markers have limited usefulness for distinguishing these carcinomas.

RESUMO

A patient who developed acute renal artery thrombosis as a complication of distal abdominal aortic occlusion is described. Because of the presence of an extensive collateral arterial supply, the right kidney survived and revascularization was accomplished successfully with a saphenous vein graft interposed between the superior mesenteric and the right renal arteries. Criteria for revascularization of renal artery occlusion are presented, with emphasis on the importance of collateral circulation and the elective correction of distal aortic thrombosis.

RESUMO

OBJECTIVE: To provide a perspective on issues in counseling the patient about treatment options for localized prostate cancer. METHODS: Review factors contributing to the uncertainty in the decision for optimal therapy for an individual with localized prostate cancer. RESULTS: There remains considerable debate relative to the need for aggressive therapy in many patients with prostate cancer, and no single therapy is universally viewed as effective. Multiple treatment options are available, including established ones, such as radical prostatectomy or external radiation therapy, and investigational ones, such as cryosurgery, implant radiation therapy, or adjuvant hormonal treatment. Multiple opinions are readily provided by physicians, friends, relatives, and others. It is valuable to strive to find the "best" treatment in an individual patient based on age, medical realities, and a patient's personal preferences. Throughout the entire process, it is important to maintain a positive, hopeful attitude to support the patient, irrespective of his choice for therapy. CONCLUSIONS: Considerable uncertainty exists relative to the ideal therapy for a patient with prostate cancer. Counseling the patient requires providing balanced information to allow a patient to participate in this often difficult decision.

RESUMO

OBJECTIVE: Examine current knowledge and concepts on the role of androgenic hormones in the epidemiology of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). METHODS: Review of the clinical and scientific literature on normal androgen physiology, hormonal physiology of BPH and PCa tissue, serum hormone levels in patients with BPH or PCa, and the correlation between serum and tissue androgenic hormones. RESULTS: BPH and PCa are enormous clinical problems for our health care system; profound changes in the clinical aspects of these diseases are evident in recent years. Early identification or prevention are realistic goals; identification of higher risk groups would be extremely valuable. Androgen stimulation of the prostate is likely to be important in the promotion of BPH or PCa. Tissue hormone measurements have not identified substantial differences in hormone levels, but precise pathologic control of the tissue examined is suspect. Examinations of serum hormone levels in disease states have produced conflicting results, but the presence or absence of BPH or PCa was often based on imprecise clinical observations, making interpretation difficult. There are minimal data confirming that the serum hormones measured previously actually reflect intraprostatic tissue activity. CONCLUSIONS: The value of serum hormone measurements to identify higher risk groups for BPH or PCa is an area of continuing uncertainty because of substantial flaws in the design of many previous studies based on a failure both to define the presence or absence of BPH or PCa precisely in patients studied and measure the appropriate androgen metabolites. Similarly, it is not possible reliably to implicate differences in androgenic stimulation as a cause for racial differences in PCa. The ability of serum hormone levels to correlate with prostatic tissue androgenic stimulation has not been evaluated. Additional research in the relationships between androgenic stimulation and the development of clinically significant BPH or PCa is needed.

RESUMO

OBJECTIVES: To define the mechanism of incontinence and retention after orthotopic neobladder diversion. METHODS: The results of urodynamic and endoscopic evaluations were assessed in 19 patients (15 men and 4 women). Mean age and postoperative follow-up were 58.3 years and 19.6 months, respectively. Seventeen patients (15 men, 2 women) presented with the sole complaint of nocturnal incontinence, and 2 women presented with retention. Evaluations included voiding and continence history, pelvic examination (for women), postvoid residual, uroflowmetry, triple-lumen video-urodynamic study, and cystourethroscopy. RESULTS: Among patients with incontinence, 11 (65%) were found to have a primary failure-to-store problem as a result of either reservoir or sphincter failure. Four patients (24%) had a primary failure-to-empty problem, and 2 (11%) had features of both. The predominant etiology of voiding difficulty was the inability to relax the external urethral sphincter adequately during Valsalva's maneuver. Of the 2 women who presented with retention, one had obstructing mucosal folds at the neobladder opening and both demonstrated anterior vaginal wall prolapse on pelvic examination. CONCLUSIONS: The mechanism of incontinence and retention after orthotopic neobladder diversion can vary. Carefully performed urodynamic and endoscopic assessments can define the underlying etiology and may serve as a guide for proper treatment selection.

RESUMO

Over a twenty-one-year period (1963-1984) 46 patients underwent a permanent urinary diversion using cutaneous ureterostomy. Thirty-seven of these patients had this method of diversion employed as palliation for pelvic malignancies. In 70 per cent of the patients diversion was done secondary to ureteral obstruction and in the other patients because of either severe lower urinary tract symptoms or a failed alternate form of diversion. Forty-nine per cent of the patients experienced a postoperative complication. The late postoperative complications were either related to the choice of diversion or presumed progression of the patient's disease. Palliative diversion is now best initially attempted with percutaneous nephrostomy or indwelling ureteral stents if bladder function allows. Cutaneous ureterostomy no longer is indicated as a primary form of palliative diversion, however, it may be used as an alternative to open nephrostomy tube placement or intestinal conduit should other more conservative forms of management fail. The presence of at least one dilated ureter is a prerequisite to the success of this form of diversion.

RESUMO

OBJECTIVES: Confidence has increased in the use of an orthotopic reservoir to the urethra after a cystoprostatectomy for bladder cancer; however, many surgeons would welcome a method to simplify the operative procedure. The availability of absorbable staples on a GIA stapler allows study of the incorporation of stapling procedures into formation of a reservoir. Because of the success of hand-sewn W-configured ileal reservoirs, we initiated a Phase II study to evaluate absorbable staples in formation of a W-configured reservoir. We now present an expanded contemporary series comparing a W-stapled ileal neobladder with hand-sewn ileal (Studer) or hand-sewn ileocolic (Le Bag) reservoirs. METHODS: Forty-five selected patients underwent orthotopic urinary diversion after cystoprostatectomy for bladder cancer (n = 42) or prostate cancer (n = 3) using one of the three methods of reservoir construction. There were 43 men and 2 women. The evaluation included a urodynamic evaluation and a questionnaire sent to patients inquiring about urinary function. RESULTS: Most patients did well with the W-stapled ileal reservoir but 6 of 19 evaluable patients had unsatisfactory reservoir characteristics. Three patients needed an augmentation cystoplasty and 3 had higher pressure, smaller volume reservoirs. Reservoir function appeared to be consistently more favorable in patients with either of the hand-sewn reservoirs using an ileal or ileocolic segment. CONCLUSIONS: Although the W-stapled ileal reservoir is safe and allows reservoir formation quickly, the inconsistencies of the results discourage its use in the particular configuration described. Failure of the reservoir to distend could be a function of reservoir design, areas of ischemia in the reservoir, or reaction to staple material. Absorbable staples on the GIA instrument may work satisfactorily for formation of an ileocolic reservoir for continent cutaneous diversion. However, the W-configured orthotopic reservoir as constructed using absorbable staples in this study is inferior to a hand-sewn ileal or ileocolic neobladder.

RESUMO

Emphysematous pyelonephritis is a severe infection found almost exclusively in diabetics, characterized by the presence of gas within the renal parenchyma. The diagnosis is established radiographically. An additional case is added to the 52 cases reported in the literature; we believe this is the fifth reported case with bilateral emphysematous pyelonephritis. If appropriate diagnostic studies demonstrate no evidence of either perinephric abscess or urinary obstruction, intensive medical management should be the initial therapy for this condition. Surgical intervention is necessary in patients without prompt response to medical therapy.

RESUMO

Fifteen patients with germ cell neoplasms (9 testicular primary, 4 extragonadal, 2 adult teratoma syndrome) with features indicative of a poor prognosis were treated with chemotherapy followed by surgery. In patients with testicular primary sites, 2 patients have relapsed and all 9 remain alive (median follow-up 36 months). In patients with extragonadal tumors 2/4 are alive without disease, and both patients with the adult teratoma syndrome have died. Combination chemotherapy and surgery can be employed successfully in this subset of patients with germ cell neoplasms.

RESUMO

Recently, techniques have been developed that allow in vitro growth and chemosensitivity testing of human malignancies. We report our initial experience with the clonogenic, or colony-forming, assay as applied to genitourinary malignancies. Over the past two years, 172 specimens of genitourinary tumors were sent for assay. Thirty-three per cent were not plated, either because of insufficient quantity of cells obtained in the sample or because of the low viability percentage as determined by trypan blue exclusion. Forty-seven per cent showed adequate growth for chemosensitivity testing whereas 20 per cent of the samples showed inadequate growth. A major problem was obtaining adequate numbers of viable cells. Several other problems make it difficult to draw clinical correlations from in vitro findings. The method appears promising for several potential applications, but further studies will be needed before the final utility of the methods is defined.

RESUMO

OBJECTIVES: Reports have demonstrated that African Americans diagnosed with prostate cancer have a poor survival compared with whites. We examined the impact of age, race, and stage of disease on survival for men diagnosed with prostate cancer. METHODS: A retrospective analysis was made of men diagnosed with prostate cancer utilizing the Surveillance, Epidemiology, and End Results Program (SEER) database. A total of 12,907 men (9339 white, 3568 black) diagnosed from January 1, 1973 through December 31, 1987 were included in the study. For each stage of disease, survival experience was examined using Kaplan-Meier and life table methods, followed by analysis using Cox's proportional hazard model. RESULTS: African-American men have a poorer survival than whites for all stages of prostate cancer when the cancer is diagnosed at younger ages. These differences in survival were not demonstrated for men diagnosed with prostate cancer after age 70. CONCLUSIONS: Age and race should be taken into account when assessing the survival of patients with prostate cancer.

RESUMO

The preoperative staging procedures used in 45 patients with surgical Stage I and Stage II nonseminomatous germ cell tumors of the testis were analyzed retrospectively. Our results indicate that gallium-67-citrate scan and supraclavicular lymph node biopsy add little information in the routine preoperative evaluation of these patients. Bipedal lymphangiography, in our experience, was no more accurate than excretory urograms in selecting patients with retroperitoneal disease and in addition provides no information regarding the status of the upper urinary tract. Thus, we suggest that physical examination, excretory urography, chest x-ray film, whole lung tomography, serum tumor markers, and liver scan provide sufficient information to proceed with surgical treatment when appropriate.

RESUMO

OBJECTIVES: To evaluate whether orthotopic urinary diversion is a viable option for patients undergoing cystoprostatectomy for radio-recurrent prostate cancer (RRPC). METHODS: Between 1990 and 1996, we performed 34 salvage surgeries for RRPC, including 26 radical retropubic prostatectomies and 8 cystoprostatectomies. We determined the operative and postoperative complication rates and pathologic stage for the 8 patients undergoing cystoprostatectomy. RESULTS: Of the 8 patients in whom cystoprostatectomy was performed, 5 underwent ileal conduit diversion and 3 underwent orthotopic neobladder reconstruction. There were no intraoperative complications or perioperative mortalities. In the group with orthotopic neobladder, postoperative complications included pyelonephritis in 1 patient and prolonged ileus in another. In the group with ileal conduit, no short-term complications occurred; 1 patient developed an incisional hernia on long-term follow-up. All patients with neobladder reconstruction are continent during the day. One patient wears one pad at night. The other 2 are continent at night. CONCLUSIONS: Orthotopic urinary diversion is a valid option for selected patients with RRPC who require a cystoprostatectomy. This procedure can be performed with minimal complications, resulting in good continence and good quality of life.

RESUMO

OBJECTIVES: Patients with prostate cancer may have more of the complexed form of prostate-specific antigen (PSA) in the serum, whereas patients with benign prostatic hyperplasia have less of this complexed form and thus a higher proportion of the free form. However, the molecular basis for the lower percent of free PSA in patients with prostate cancer remains unknown, and considerable overlap in values exists. We examined this hypothesis in men with recurrent or persistent cancer after radical prostatectomy. These men, who have "pure" cancer in that they have no benign elements to their disease, should have very low percent free PSA values. METHODS: Forty-six men with recurrent (persistent) cancer as manifested by rising PSA values (mean [+/-SD] 2.4 +/- 2.5 ng/mL) after radical prostatectomy were available for analysis. Specimens were analyzed with the use of the Abbott AxSYM free and total PSA assays. The Mann-Whitney U test was used to compare percent free PSA values in this recurrent cancer group with values from a previously defined population of 413 men (225 with benign disease and 188 with prostate cancer before prostatectomy). RESULTS: Median values of percent free PSA in the recurrent cancer group (8.4%) were significantly lower than values in the preoperative cancer (11.7%) or benign (17.4%) groups (P < 0.0001 for both comparisons). Among patients in the "pure" cancer group, 30 (65%) had values less than 10%; however, 4 patients (9%) had values from 1 5% to 1 9%, and another 4 (9%) had values of 20% or greater. Pathologically, patients with higher values (15% or greater) had aggressive disease. All patients with values of 20% or greater had evidence of seminal vesicle involvement or nodal disease. CONCLUSIONS: Although most cancers exhibit low values of percent free PSA, a significant proportion of aggressive tumors will demonstrate high values. Until this latter phenomenon can be explained, the widespread use of percent free PSA to distinguish benign from malignant disease or to stage confirmed malignant disease should be approached with caution.
