Outcomes of urinary diversion after surgery for locally advanced or locally recurrent rectal cancer with complete cystectomy; ileal and colon conduit.

INTRODUCTION: Surgery for locally advanced rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) may require total pelvic exenteration with the need for urinary diversion. The aim of this study was to describe outcomes for ileal and colon conduits after surgery for LARC and LRRC. METHODS: All consecutive patients from two tertiary referral centers who underwent total pelvic exenteration for LARC or LRRC between 2000 and 2018 with cystectomy and urinary reconstruction using an ileal or colon conduit were retrospectively analyzed. Short- (≤30 days) and long-term (>30 days) complications were described for an ileal and colon conduit. RESULTS: 259 patients with LARC (n = 131) and LRRC (n = 128) were included, of whom 214 patients received an ileal conduit and 45 patients a colon conduit. Anastomotic leakage of the ileo-ileal anastomosis occurred in 9 patients (4%) after performing an ileal conduit. Ileal conduit was associated with a higher rate of postoperative ileus (21% vs 7%, p = 0.024), but a lower proportion of wound infections than a colon conduit (14% vs 31%, p = 0.006). The latter did not remain significant in multivariate analysis. No difference was observed in the rate of uretero-enteric anastomotic leakage, urological complications, mortality rates, major complications (Clavien-Dindo≥3), or hospital stay between both groups. CONCLUSION: Performing a colon conduit in patients undergoing total pelvic exenteration for LARC or LRRC avoids the risks of ileo-ileal anastomotic leakage and may reduce the risk of a post-operative ileus. Besides, there are no other differences in outcome for ileal and colon conduits.

Total pelvic exenteration for locally advanced and locally recurrent rectal cancer in the elderly.

BACKGROUND: Total pelvic exenteration (TPE) is a radical approach for locally advanced rectal cancer (LARC) and locally recurrent rectal cancer (LRRC) in case of tumour invasion into the urogenitary tract. The aim of this study is to assess surgical and oncological outcomes of TPE for LARC and LRRC in elderly patients compared to younger patients. METHODS: All patients who underwent TPE for LARC and LRRC between January 1990 and March 2017 were retrospectively analyzed. Patients aged <70 years were classified as younger and ≥70 years as elderly patients. RESULTS: In total 126 patients underwent TPE, of whom 88 younger and 38 elderly patients. Elderly patients had a significantly higher number of ASA > II patients (p = 0.01). Indication for surgery LARC (n = 73) and LRRC (n = 53) did not differ significantly. The 30-day mortality rate was significantly higher (p = 0.01) in elderly (13%) compared to younger patients (3%). Elderly patients experienced more anastomotic leakage (p = 0.02). Median overall survival (OS) was 75 months [95%CI 37.1; 112.9] for elderly and 45 months [95%CI 22.4; 67.8] for younger patients (p = 0.77). The 5-year OS rate was 44% in both groups. Median disease specific survival (DSS) was 78 months [95%CI 69.1; 86.9] for elderly and 60 months [95%CI 36.6; 83.4] for younger patients (p = 0.34). The 5-year DSS rate was 57% and 49%, respectively. CONCLUSION: TPE is an invasive treatment for rectal cancer with high 30-day mortality in elderly patients. Oncological outcomes are similar in elderly and younger patients. Therefore, TPE should not be withheld because of high age only, but careful patient selection is needed.

Comparison of 30-day, 90-day and in-hospital postoperative mortality for eight different cancer types.

BACKGROUND: Various definitions are used to calculate postoperative mortality. As variation hampers comparability between reports, a study was performed to evaluate the impact of using different definitions for several types of cancer surgery. METHODS: Population-based data for the period 1997-2008 were retrieved from the Rotterdam Cancer Registry for resectional surgery of oesophageal, gastric, colonic, rectal, breast, lung, renal and bladder cancer. Postoperative deaths were tabulated as 30-day, in-hospital or 90-day mortality. Postdischarge deaths were defined as those occurring after discharge from hospital but within 30 days. RESULTS: This study included 40,474 patients. Thirty-day mortality rates were highest after gastric (8·8 per cent) and colonic (6·0 per cent) surgery, and lowest after breast (0·2 per cent) and renal (2·0 per cent) procedures. For most tumour types, the difference between 30-day and in-hospital rates was less than 1 per cent. For bladder and oesophageal cancer, however, the in-hospital mortality rate was considerably higher at 5·1 per cent (+1·3 per cent) and 7·3 per cent (+2·8 per cent) respectively. For gastric, colonic and lung cancer, 1·0 per cent of patients died after discharge. For gastric, lung and bladder cancer, more than 3 per cent of patients died between discharge and 90 days. CONCLUSION: The 30-day definition is recommended as an international standard because it includes the great majority of surgery-related deaths and is not subject to discharge procedures. The 90-day definition, however, captures mortality from multiple causes; although this may be of less interest to surgeons, the data may be valuable when providing information to patients before surgery.

Cervical lymph node dissection for metastatic testicular cancer.

INTRODUCTION: Despite high response rates to systemic chemotherapy, 30% of patients with advanced stage testicular carcinoma will have extra-retroperitoneal residual masses that require resection. Most often, these are located in the lungs and mediastinum and neck. Limited data are available concerning the incidence, surgical management, and follow-up of neck metastasis arising from a testicular primary tumor. METHODS: We retrospectively reviewed all 665 patients who were referred to a tertiary referral center with the diagnosis of testicular cancer from January 1997 to June 2009 for the presence of cervical metastases. Patients who underwent concomitant surgical therapy were identified and analyzed. Clinical and pathological data were collected from patient records, including radiology and pathology reports. Furthermore, data on primary treatment strategy, chemotherapeutic regimens, timing of surgical procedures, complications, disease recurrence, and follow-up were collected. RESULTS: Twenty-six patients (4%) had cervical lymph node metastasis. The majority (n = 19) had multiple ERP sites. Nine patients (35%) underwent selective neck dissection: in six patients, this was indicated because of residual masses after chemotherapy, and in three patients, cervical masses represented a late and distant relapse of previously treated disease. Viable cancer cells were present in the resected specimen only in these three patients. Seven patients are currently without evidence of disease. Two patients died of disseminated disease. CONCLUSIONS: Cervical lymph node metastases originating from testicular cancer are rare but are more commonly observed in patients with advanced stage disease. Selective neck dissection can be safely performed both after chemotherapy and in the case of recurrent disease.

Total pelvic exenteration for primary and recurrent malignancies.

INTRODUCTION: Complete resection is the most important prognostic factor in surgery for pelvic tumors. In locally advanced and recurrent pelvic malignancies, radical margins are sometimes difficult to obtain because of close relation to or growth in adjacent organs/structures. Total pelvic exenteration (TPE) is an exenterative operation for these advanced tumors and involves en bloc resection of the rectum, bladder, and internal genital organs (prostate/seminal vesicles or uterus, ovaries and/or vagina). METHODS: Between 1994 and 2008, a TPE was performed in 69 patients with pelvic cancer; 48 with rectal cancer (32 primary and 16 recurrent), 14 with cervical cancer (1 primary and 13 recurrent), 5 with sarcoma (3 primary and 2 recurrent), 1 with primary vaginal, and 1 with recurrent endometrial carcinoma. Ten patients were treated with neoadjuvant chemotherapy and 66 patients with preoperative radiotherapy to induce down-staging. Eighteen patients received IORT because of an incomplete or marginal complete resection. RESULTS: The median follow-up was 43 (range, 1-196) months. Median duration of surgery was 448 (range, 300-670) minutes, median blood loss was 6,300 (range, 750-21,000) ml, and hospitalization was 17 (range, 4-65) days. Overall major and minor complication rates were 34% and 57%, respectively. The in-hospital mortality rate was 1%. A complete resection was possible in 75% of all patients, a microscopically incomplete resection (R1) in 16%, and a macroscopically incomplete resection (R2) in 9%. Five-year local control for primary locally advanced rectal cancer, recurrent rectal cancer, and cervical cancer was 89%, 38%, and 64%, respectively. Overall survival after 5 years for primary locally advanced rectal cancer, recurrent rectal cancer, and cervical cancer was 66%, 8%, and 45%. CONCLUSIONS: Total pelvic exenteration is accompanied with considerable morbidity, but good local control and acceptable overall survival justifies the use of this extensive surgical technique in most patients, especially patients with primary locally advanced rectal cancer and recurrent cervical cancer.

Total pelvic exenteration for primary locally advanced and locally recurrent rectal cancer.

AIMS: To report the role of total pelvic exenteration in a series of locally advanced and recurrent rectal cancers. METHODS: In the period 1994-2004, TPE was performed in 35 of 296 patients with primary locally advanced and recurrent rectal cancer treated in the Daniel den Hoed Cancer Center; 23 of 176 with primary locally advanced and 12 of 120 with recurrent rectal cancer. All but one patient received pre-operative External Beam Radiation Therapy (EBRT). After 1997, Intra Operative Radiotherapy (IORT) was performed in case of a resection margin less than 2 mm. RESULTS: Overall major complication rates were not significantly different between patients with primary and recurrent rectal cancer (26% vs. 50%, p=0.94). The hospital mortality rate was 3%. The 5-year local control and overall survival of patients with primary locally advanced rectal cancer were 88% and 52%, respectively. In patients with recurrent rectal cancer 3-year local control and survival rates were 60% and 32%, respectively. An incomplete resection, preoperative pain and advanced Wanebo stage for recurrent cancer were negative prognostic factors for both local control and overall survival. CONCLUSION: TPE in primary locally advanced rectal cancer enables good local control and acceptable overall survival, thereby justifying the use of the procedure. Patients with recurrent rectal cancer showed a high rate of major complications, a high distant metastasis rate, and a poor overall survival.

Tumor characteristics and prognostic factors in two subsequent screening rounds with four-year interval within prostate cancer screening trial, ERSPC Rotterdam.

OBJECTIVES: To evaluate the tumor characteristics and prognostic factors in screen-detected prostate cancers in two successive screening rounds with a 4-year screening interval in the European Randomized Study of Screening for Prostate Cancer, section Rotterdam. METHODS: From 1993 to 2000, 42,376 men (21,210 in the screening arm and 21,166 in the control arm) were randomized and screened. Prostate-specific antigen testing, digital rectal examination, transrectal ultrasonography, and sextant biopsies were offered to the participants in the screening arm. A total of 1218 men with a biopsy indication at the first screening received an additional screening after 1 year (early recall). By 2004, all men had received their second screening. Interval carcinomas were defined as cancers detected during the screening interval and were identified by linkage with the Cancer Registry. RESULTS: In the first round, 1014 prostate cancers were detected--24 in the men noncompliant to screening, 63 at the early recall screening, and 433 in the second round of screening. Also, 62 interval carcinomas were diagnosed. In the second screening round, the mean prostate-specific antigen value was lower (5.6 versus 11.1 ng/mL), advanced clinical stage T3-T4 was 7.1-fold less common, and 76.4% versus 61.5% of the biopsy Gleason scores were less than 7. In the first screening round, 13 regional and 9 distant metastases were detected; in the second round, 2 cases with distant metastasis were found. CONCLUSIONS: Overall, a shift toward more favorable tumor characteristics was seen for the second round of screening. These results support the screening methods used and the interscreening interval of 4 years.

Laparoscopic versus open donor nephrectomy: ureteral complications in recipients.

OBJECTIVES: To describe our experience with laparoscopic donor nephrectomy (LDN) and open donor nephrectomy (ODN) regarding ureteral complications. LDN has proved to be safe and to offer significant benefits to the donor compared with ODN. Of major importance is the effect of the surgical technique on the graft. Studies have shown an increased incidence of ureteral complications in recipients of laparoscopically procured kidneys. Operative reconstruction results in additional morbidity for the recipient. METHODS: Living donors and their recipients, who underwent surgery from January 1994 to April 2002, were included in this retrospective study. A total of 122 LDN and 77 ODN recipients were included. RESULTS: Of the 122 LDN and 77 ODN recipients, 15 (12%) and 10 (13%), respectively, required percutaneous nephrostomy drainage. In total, 5 LDN (4.1%) and 5 ODN (6.5%) recipients required reconstruction of the ureter because of obstruction of the ureter or urine leakage (P value not statistically significant, excluding reconstruction required for technical errors). The operating time, warm ischemia time, and serum creatinine were comparable between recipients with or without ureter complications requiring reconstruction. CONCLUSIONS: In our experience, LDN was not associated with an increased incidence of ureteral complications in the recipient compared with ODN.

Measuring disease specific quality of life in localized prostate cancer: the Dutch experience.

OBJECTIVE: We aimed at developing and testing a Dutch health-related quality of life measure for localized prostate cancer patients. METHODS: Scales on urinary and bowel function and bother from the UCLA Prostate Cancer Index (PCI) underwent formal linguistic and cultural translation. PCI sexual scales were replaced by an existing Dutch sexual activities module (SAc). After qualitative pilot testing 389 patients with localized prostate cancer (mean age 67 +/- 7 years) completed the measure before and at 2 time points after primary treatment. Psychometric properties (feasibility, score distribution, reliability, construct validity and responsiveness to change) of the new instrument were analyzed. RESULTS: Response rates ranged from 93% at baseline to 87% after treatment. Urinary and bowel function scales showed Cronbach's alphas >0.7. Urinary function and bother, and bowel function and bother were significantly correlated. Pre- vs. post-prostatectomy effect sizes were >0.9 only for urinary scales; while pre- vs. post-radiotherapy effect sizes were >0.75 only for bowel scales. Six months after baseline erectile dysfunction was reported by 64% of respondents, either as a problem in sexual activity or as a reason for not being sexually active. CONCLUSION: The Dutch PCI and SAc performed well in men treated for early stage prostate cancer.

Features and preliminary results of the Dutch centre of the ERSPC (Rotterdam, the Netherlands).

OBJECTIVE: To describe the preliminary results of the Dutch section of a large multicentre study of screening for prostate cancer, the European Randomized study of Screening for Prostate Cancer (ERSPC), initiated in the Netherlands and Belgium in 1991. MATERIALS AND METHODS: After a series of five pilot studies which started in 1991, full-capacity screening started in 1994 with the use of a serum prostate-specific antigen (PSA) determination, a digital rectal examination (DRE) and transrectal ultrasonography (TRUS) as screening tests. Depending on the results and the screening protocol used, men were referred for further examination by sextant biopsies (extended with a seventh biopsy if TRUS showed abnormality). The protocols used, efficiency of the different screening tests, number of cancers detected in the pilot studies, initial screening round and preliminary results of the second screening round are described. RESULTS: After the pilot studies it became clear that a study of prostate cancer screening was feasible in the Rotterdam area. The screening protocol was workable and the recruitment rate acceptable (39.5%). An inventory of the population registries of Rotterdam and surrounding municipalities, and the known recruitment rate, made it clear that a contribution of 40000 men (aged 55-74 years) from the Dutch centre to the ERSPC was feasible. The initial screening round started in December 1993 and lasted until December 1999 (protocol 5-10). In all, 42376 men were randomized and 1014 cancers detected (5.1%). During this screening the protocol was simplified. After evaluating the different screening tests abnormal results of the DRE and TRUS were omitted as an indication for a sextant biopsy. Only a serum PSA level of > or = 3.0 ng/mL is now used as the indication. The second screening round started in December 1997 and continues. To December 2002, 9920 men were screened for the second time, 4 years after their initial screening visit. To date 446 cancers have been detected (4.5%); this round will last to December 2003. Further evaluation of the screening regimen and characteristics of the cancers detected are constantly assessed within the Dutch ERSPC. Meanwhile a third screening round has also been initiated, which will last to December 2007. CONCLUSIONS: A prostate cancer screening study of the projected magnitude is feasible in Rotterdam; the recruitment rate is acceptable and the screening tests well tolerated. The study has generated many scientific publications and will be of great value in determining whether prostate cancer screening should be part of general healthcare.

Microsatellite analysis--DNA test in urine competes with cystoscopy in follow-up of superficial bladder carcinoma: a phase II trial.

BACKGROUND: It has been shown that microsatellite analysis (MA) is able to detect bladder carcinoma in urine. Relatively small groups of patients often with high stage and grade disease were investigated. However, greater than 85% of cystoscopies are performed for follow-up of superficial bladder carcinoma. The authors evaluated this DNA-based method in a group of consecutive patients in follow-up after transurethral resection of superficial disease. METHODS: Matched blood and urine samples from 109 patients were obtained before cystoscopy and subjected to MA. The BTA stat test (Bard Diagnostic Sciences, Inc., Redmond, WA) and cytology were used for comparison. RESULTS: Sixteen patients were excluded: the DNA was of insufficient quality for 7 patients and leukocyte abundance rendered the result of MA unreliable for 9 patients. For the remaining 93 patients, MA detected 18 of the 24 recurrent tumors. The six undetected tumors were small pTaG1 lesions for which immediate surgery was not necessary. Conversely, 5 of 9 patients with a positive MA and a negative cystoscopy had a tumor recurrence within 6 months after urine collection. In contrast, a recurrence occurred in only 7 of 60 patients who were negative in both MA and cystoscopy (P = 0.006). The MA (74%) appeared more sensitive than the BTA stat test (56%) or urine cytology (22%). CONCLUSIONS: Microsatellite analysis is a DNA test in urine that reliably signals the presence of recurrent bladder carcinoma, sometimes even before cystoscopic evidence of the disease. This noninvasive diagnostic tool has the potential to replace cystoscopy in many cases. The authors' results warrant the need for randomized trials.

Intravesical instillation of epirubicin, bacillus Calmette-Guerin and bacillus Calmette-Guerin plus isoniazid for intermediate and high risk Ta, T1 papillary carcinoma of the bladder: a European Organization for Research and Treatment of Cancer genito-urinary group randomized phase III trial.

PURPOSE: After transurethral resection, we compared the efficacy and side effects of weekly intravesical instillations of epirubicin, bacillus Calmette-Guerin (BCG), and BCG plus isoniazid during a 6-week interval followed by 3 weekly maintenance instillations at months 3, 6, 12, 18, 24, 30 and 36 in patients with intermediate and high risk Ta, T1 bladder cancer. MATERIALS AND METHODS: A total of 957 patients were randomized at 44 institutions in a phase III multicenter trial. RESULTS: The time to first recurrence was significantly longer in patients treated with BCG and BCG plus isoniazid compared to epirubicin (p = 0.0001) but there was no difference between the 2 BCG regimens (p = 0.27). Progression to muscle invasive cancer was rare (5%) and did not differ significantly among the 3 arms (p = 0.12). Drug induced cystitis was observed in 31% of the patients treated with epirubicin, 42% BCG and 45% BCG plus isoniazid. Systemic side effects, such as fever and malaise, were not observed in patients treated with epirubicin, but were noted in 31% BCG and 36% BCG plus isoniazid. CONCLUSIONS: Intravesical BCG with or without isoniazid provokes more side effects than epirubicin. Prophylactic isoniazid does not reduce the side effects of BCG, while BCG with or without isoniazid prolongs the time to first recurrence compared to epirubicin. Further followup is required before long-term conclusions can be made for progression-to-muscle invasive disease and survival.

Long-term graft survival after urological complications of 695 kidney transplantations.

PURPOSE: We ascertain the incidence, management and long-term outcome of early urological complications requiring surgical exploration in kidney transplantation. MATERIALS AND METHODS: Data of 695 consecutive kidney transplantations performed between January 1985 and January 1997 were assessed in regard to urological complications that occurred within 1 year after transplant. A computerized database was used to analyze graft recipient characteristics, the implantation procedure, complications and outcome in select patients and all those who underwent transplant during the same period. In the noncomplication group sufficient data for evaluation was available for 556 patients. We performed the Cox proportional hazards analysis with overall graft failure, graft failure or death as end points of observation. RESULTS: Overall, 42 (6.0%) patients required revision of vesicoureteral anastomosis. Complications were identified after a median of 6 days (range 0 to 135). The primary reconstruction technique was extravesical in 64% and transvesical in 33% of patients, including 1 that involved ureteral Bricker anastomosis. Obstruction and/or leakage at vesicoureteral anastomosis accounted for 69% of urological complications. Revision was performed with a number of different reconstruction techniques. A second revision was required in 16.7%. Mean followup after primary transplant was 9.1 years (range 3.2 to 15). Multivariate analysis showed that surgical treatment of urological complication during year 1 after kidney transplantation did not increase the risk of overall graft failure, graft failure or death. CONCLUSIONS: Our results indicate that long-term graft survival is not affected by a surgically treated urological complication.

Health-related quality-of-life effects of radical prostatectomy and primary radiotherapy for screen-detected or clinically diagnosed localized prostate cancer.

PURPOSE: The current study was undertaken within the framework of a screening trial to compare the health-related quality-of-life (HRQOL) outcomes of two primary treatment modalities for localized prostate cancer: radical prostatectomy and external-beam radiotherapy. PATIENTS AND METHODS: We conducted a prospective longitudinal cohort study among 278 patients with early screen-detected (59%) or clinically diagnosed (41%) prostate cancer using both generic and disease-specific HRQOL measures (SF-36, UCLA Prostate Cancer Index [urinary and bowel modules] and items relating to sexual functioning) at three points in time: t1 (baseline), t2 (6 months later), and t3 (12 months after t1). RESULTS: Questionnaires were completed by 88% to 93% of all initially enrolled patients. Patients referred for primary radiotherapy were significantly older than prostatectomy patients (63 v 68 years, P <.01). Analyses (adjusted for age and pretreatment level of functioning) revealed poorer levels of generic HRQOL after radiotherapy. Prostatectomy patients reported significantly higher (P <.01) posttreatment incidences of urinary incontinence (39% to 49%) and erectile dysfunction (80% to 91%) than radiotherapy patients (respectively, 6% to 7% and 41% to 55%). Bowel problems (urgency) affected 30% to 35% of the radiotherapy group versus 6% to 7% of the prostatectomy group (P <.01). Patients with screen-detected and clinically diagnosed cancer reported similar posttreatment HRQOL. CONCLUSION: Prostatectomy and radiotherapy differed in the type of HRQOL impairment. Because the HRQOL effects may be valued differently at the individual level, patients should be made fully aware of the potential benefits and adverse consequences of therapies for early prostate cancer. Differences in posttreatment HRQOL were not related to the method of cancer detection.

The fibroblast growth factor receptor 3 (FGFR3) mutation is a strong indicator of superficial bladder cancer with low recurrence rate.

We analyzed the possible prognostic value of the recently discovered fibroblast growth factor receptor 3 (FGFR3) mutations in bladder cancer. A FGFR3 mutation was found in 34 of 53 pTaG1-2 bladder cancers, whereas none of the 19 higher-staged tumors had a mutation (P < 0.0001). In 57 patients with superficial disease followed prospectively by cystoscopy for 12 months, 14 of 23 patients in the wild-type FGFR3 group developed recurrent bladder cancer compared with only 7 of 34 patients in the mutant group (P = 0.004). The recurrence rate per year was 0.24 for the FGFR3 mutant tumors and 1.12 for tumors with a wild-type FGFR3 gene. In addition, FGFR3 mutation status was the strongest predictor of recurrence when compared with stage and grade (P = 0.008). This is the first mutation in bladder cancer that selectively identifies patients with favorable disease characteristics. Our results suggest that the frequency of cystoscopic examinations can be reduced considerably in patients with FGFR3-positive tumors.

Health-related quality of life in patients with screen-detected versus clinically diagnosed prostate cancer preceding primary treatment.

BACKGROUND: The purpose of this study was to evaluate baseline health-related quality of life (HRQOL) in patients with localized prostate cancer before primary treatment (radical prostatectomy or radiotherapy). METHODS: Two hundred patients with newly diagnosed localized (screen-detected or clinically diagnosed) prostate cancer completed HRQOL questionnaires (generic and disease-specific measures). Clinical data were collected from patients' medical records in four Rotterdam hospitals. RESULTS: Screen-detected tumors were of more favorable stages and grades than clinically diagnosed ones. The diagnostic groups did not differ significantly in bowel and sexual functioning. Differences were found in urinary functioning, favoring patients with screen-detected tumors of T2-T3 stages. Patients with screen-detected T2 cancer reported better generic HRQOL (physical aspects) than the clinical group, but HRQOL of the latter group was similar to the population norm. Radiotherapy patients were significantly older and had more comorbidity than subjects referred to prostatectomy. Urinary, bowel, and sexual problems were uncommon. Older (> 65 years) radiotherapy patients appeared to be less sexually active. Radiotherapy patients also reported poorer levels of generic HRQOL. CONCLUSIONS: Screen-detected prostate cancer patients presented with more favorable cancer stage and grade. HRQOL was related to both the tumor stage and the detection method. Pre-treatment HRQOL differences between prostatectomy and radiotherapy patients were associated neither with tumor characteristics nor with the detection method. Baseline differences in HRQOL should be taken into account when evaluating post-treatment HRQOL.

Why do men refuse or attend population-based screening for prostate cancer?

BACKGROUND: The aims of this study were to investigate the motives for refusing or attending population-based screening for prostate cancer, in relation to various background characteristics. METHODS: The present study is part of the European Randomized Study of Screening for Prostate Cancer (ERSPC), and took place in 1995-1996. Men aged 55-75 years were invited using the Rotterdam population registry (100 per cent coverage), of whom 42 per cent gave written informed consent. These men were randomized to receive either determination of prostate specific antigen (PSA), digital rectal examination (DRE), transrectal ultrasound (TRUS) and biopsy on indication (screening group), or no screening (control group). To 626 consecutive men of the screening group a questionnaire was sent before the screening. To 500 randomly selected refusers (no written informed consent) a similar questionnaire was sent, followed by two reminders. In both refusers and attenders we addressed motives, knowledge of prostate cancer, attitudes towards screening, background characteristics and urological complaints (American Urological Association symptom index, AUA7). RESULTS: Response rates for questionnaires were 48 per cent in refusers and 99 per cent in attenders. Main reported motives for refusing were absence of urological complaints (57 per cent) and anticipated pain or discomfort (18 per cent). Main reported motives for attending were personal benefit (82 per cent), contribution to science (49 per cent) and presence of urological complaints (25 per cent). Compared with attenders, refusers were slightly and significantly older, less often married and had a lower level of education; they had less knowledge about prostate cancer and a less positive attitude towards screening; they had worse general health but fewer urological complaints (AUA7 median 2 versus 4, p < 0.001). CONCLUSION: In refusing or attending population-based prostate cancer screening, urological complaints but also knowledge, attitudes and sociodemographic factors seem to play a role. Therefore, the approach of the general population should be carefully considered.

Retroperitoneal metastases in testicular cancer: role of CT measurements of residual masses in decision making for resection after chemotherapy.

PURPOSE: To determine the relative importance of computed tomographic (CT) measurements for the prediction of histologic findings in residual masses in patients with nonseminomatous testicular cancer. MATERIALS AND METHODS: Measurements of the maximum transverse size of retroperitoneal metastases before and after chemotherapy were available in 641 patients who underwent resection after chemotherapy while their levels of tumor markers were normal. Radiologic measurements of mass size and clinical characteristics (histologic findings in primary tumor and levels of alpha-fetoprotein, human chorionic gonadotropin, and lactate dehydrogenase before chemotherapy) were related to histologic findings in the residual mass with logistic regression analysis. RESULTS: At resection, 302 patients had benign tissue, and 339 had residual tumor (mature teratomas or cancer). Tumor was more frequent in larger masses after chemotherapy but was unrelated to mass size before chemotherapy. Inclusion of the reduction in size significantly improved the logistic regression model, which included mass size after chemotherapy. This model was further improved with the addition of clinical characteristics. Areas under the receiver operating characteristic curves increased from 0.74 to 0.77 and 0.83 with these models. CONCLUSION: A small retroperitoneal mass after chemotherapy is an important predictor of benign histologic findings in residual masses in patients with nonseminomatous testicular cancer. However, better predictions can be made when the reduction in size and clinical characteristics are considered as well. Decisions regarding resection should be based on the combination of these characteristics rather than on only mass size after chemotherapy.

Trends in the curative treatment of localized prostate cancer after the introduction of prostate-specific antigen: data from the Rotterdam Cancer Registry.

OBJECTIVE: To investigate changes in the incidence and treatment of prostate cancer over the period in which new diagnostic tools were introduced and the attitude towards treatment was changing. PATIENTS AND METHODS: Information on the extent of disease and treatment of patients diagnosed with prostate cancer within the Rotterdam region was retrieved from the Rotterdam Cancer Registry. RESULTS: In the period 1989-95, 4344 patients were diagnosed with prostate cancer and the age-standardized incidence increased from 62 to 125 per 100 000 men. This increase mainly comprised tumours localized to the prostate, while the incidence of advanced cancers remained stable. The proportion of poorly differentiated tumours decreased from 33% in 1989 to 24% in 1995. In the same period the number of patients receiving radiotherapy increased from 80 to 258, while the annual number of radical prostatectomies rose from 17 to 159. Radiotherapy was the preferred type of treatment in patients over 70 years of age, whereas radical prostatectomy was used more frequently in younger patients with localized tumours. CONCLUSION: While the value of screening for prostate cancer remains in debate, incidence and treatment patterns are changing rapidly. Information on patterns of care is needed to interpret future mortality data and to plan resources for adequate health care.
