Efficacy of CPITN sextant scores for detection of periodontitis disease activity.

The relationship between CPITN sextant scores and periodontitis recurrence at individual tooth sites was evaluated in a longitudinal study in 83 treated adult periodontitis patients receiving systematic 3-month maintenance care. At baseline and semi-annual examinations over 36 months, CPITN scores were assigned to each dentition sextant using probing depths and gingival index scores, and relative periodontal attachment level was assessed at individual tooth sites using an occlusal reference stent. Periodontitis recurrence was defined as any periodontal site exhibiting either a probing depth increase of > or = 3 mm from baseline, or a probing depth increase of > or = 1 mm from baseline together with a loss of relative periodontal attachment of > or = 2 mm from baseline. 49 (59.0%) subjects developed periodontitis recurrence in 147 (29.8%) sextants at 181 (2.2%) individual periodontal sites during the 36-month study period. Baseline CPITN scores of 4 were more common in disease-active subjects than clinically-stable subjects (p = 0.003, t-test), and were associated with a statistically significant 1.66 relative risk of periodontitis recurrence within 36 months. CPITN sextant scores of 3 or 4 showed low specificity and low positive predictive values as indicators of periodontitis recurrence at > or = 1 individual sites within the affected sextant. In comparison, low CPITN sextant scores (0-2) provided high specificity (96.2-100%), high positive predictive values (99.5-100%), and a summary odds ratio of 24.2 as an indicator of clinical stability at all periodontal sites within a given dentition sextant. Changes in sextant scores for CPITN over 6-month periods showed no relationship with periodontitis recurrence at individual periodontal sites. This study suggests that while CPITN is inadequate for detection of periodontitis recurrence, low CPITN scores provide rapid presumptive identification of clinically-stable sextants in adult periodontitis patients on maintenance care.

Tertiary Gleason pattern 5 is a powerful predictor of biochemical relapse in patients with Gleason score 7 prostatic adenocarcinoma.

PURPOSE: In radical prostatectomy specimens Gleason score 7 is among the most commonly assigned scores for prostate carcinoma accounting for 30% to 50% of cases. Gleason score 7 is different from other more differentiated prostate carcinomas (tumors of Gleason scores 5 and 6) with a significantly worse outcome and higher rate of recurrence. Nonetheless, Gleason score 7 tumors are heterogeneous. In this study we examined the differences in clinical outcome between primary Gleason grade 3 and 4 tumors in patients who underwent radical prostatectomy, and determined the influence of tertiary Gleason pattern 5 on patient outcome. MATERIALS AND METHODS: A total of 504 patients underwent radical prostatectomy for prostate cancer and 228 of the patients (45%) had a Gleason score of 7. Cases were analyzed for a variety of clinical and pathological parameters. The influence of primary Gleason pattern and tertiary Gleason pattern 5 on patient outcome was assessed in the Cox regression model. RESULTS: Among 228 patients with Gleason score 7 prostatic adenocarcinoma, 91 (40%) had a primary Gleason pattern 4 and 137 (60%) had primary Gleason pattern 3. Patients of the former group were more likely to have a higher pathological stage (p = 0.003), more likely to have PSA recurrence (p = 0.02) and more likely to have a tertiary Gleason pattern 5 (p <0.0001). A total of 37 (41%) patients with primary Gleason 4 had a tertiary Gleason pattern 5, whereas only 13 (9%) patients with primary Gleason 3 had a tertiary Gleason pattern 5. In the Cox regression model controlling for tumor stage and surgical margin status, the primary Gleason pattern was not an independent predictor of PSA recurrence (p = 0.80), whereas the presence of tertiary Gleason pattern 5 was a significant predictor of PSA recurrence (hazard ratio 2.10, 95% CI 1.24-3.55, p = 0.006). Five-year PSA recurrence-free survival was 70% for patients without a tertiary Gleason pattern 5 compared to 19% for those patients with a tertiary Gleason pattern 5. CONCLUSIONS: Among patients with Gleason score 7, primary Gleason grade 4 indicates a likelihood of higher tumor stage and higher probability of PSA recurrence than does primary pattern 3. However, it does not independently predict a worse outcome after controlling for other known prognostic parameters associated with disease progression. Regardless of whether the primary Gleason pattern is 3 or 4, a tertiary Gleason pattern 5 is the strongest predictor of a worse outcome in patients with Gleason grade 7 prostatic adenocarcinoma. Therefore, tertiary pattern 5 should be reported in radical prostatectomy specimens.

Arthroscopic Bankart repair using suture anchors in athletes: patient selection and postoperative sports activity.

PURPOSE: The purpose of this study was to evaluate the results in selected high-risk patients who underwent arthroscopic stabilization of shoulders with recurrent anterior instability. HYPOTHESIS: Arthroscopic stabilization using suture anchors is useful for athletes younger than 25 years or for contact athletes without a large bone loss of glenohumeral articulation. STUDY DESIGN: Prospective cohort study. METHODS: The study group comprised 55 patients, with a mean follow-up of 42 months (range, 25-72 months). Thirty-two patients had recurrent dislocations, 14 had recurrent subluxations, and 9 had recurrent subluxations after a single dislocation. Rowe score, range of motion, recurrence, and sports activities were evaluated. RESULTS: Mean Rowe score improved from 30.1 to 92.3 points; 45 scores (82%) were excellent, 5 (9%) good, 1 fair (2%), and 4 (7%) poor. Patients had lost a mean of 4 degrees of external rotation in adduction. Four (7%) had recurrence. The recurrence rate in contact athletes (9.5%, 2 of 21) was not statistically different from that in noncontact athletes (6%, 2 of 34). Forty-four (80%) returned at the same levels. The complete return rate in overhead-throwing athletes (68%, 17 of 25) was lower than that in nonoverhead athletes (90%, 27 of 30) (P = .0423). Five patients had unsatisfactory results. CONCLUSION: Arthroscopic stabilization is a reliable procedure in selected high-risk patients.

The hypo-osmotic swelling test in recurrent miscarriage.

OBJECTIVE: To determine whether there is any association between sperm membrane integrity as determined by the hypo-osmotic swelling test score and unexplained recurrent miscarriage. DESIGN: Prospective observational study. SETTING: Tertiary referral center for recurrent miscarriage. PATIENT(S): Semen samples from 20 male partners of women who had had three or more first trimester miscarriages of unexplained etiology and semen samples from 20 prospective semen donors of unknown fertility potential. MAIN OUTCOME MEASURE(S): Sperm density, sperm motility, sperm morphology, and hypoosmotic swelling test score. RESULT(S): There was no difference in the median sperm density, the mean sperm motility, or the mean sperm morphology between the two groups. However, the recurrent miscarriage group had a significantly lower hypo-osmotic swelling test score than the control group. CONCLUSION(S): The hypo-osmotic swelling test score is significantly lower in samples from men whose partners have had unexplained recurrent spontaneous abortions. With the exception of cytogenetic abnormalities in peripheral blood karyotype, this is the first study to identify a male factor component in recurrent miscarriage.

Type A score (Jenkins Activity Survey) and risk of recurrent coronary heart disease in the aspirin myocardial infarction study.

The Jenkins Activity Survey (JAS), a questionnaire developed to assess the type A behavior pattern, was administered to 2,314 participants in the Aspirin Myocardial Infarction Study. All had a myocardial infarction (MI) before entering the study and were followed for at least 3 years. The JAS type A score was not significantly related to risk of recurrent major coronary events (definite nonfatal MI and coronary death) in the group of 244 women, the group of 2,070 men, or the subgroup of 671 men who were employed full-time in professional, technical or managerial positions. These results indicate that the JAS type A score is not useful in assessing prognosis after MI. By inference, traits measured by the JAS type A score, such as competitiveness, orientation toward achievement and preference for a rapid pace of life, appear not to be associated with increased risk of recurrent major coronary events.

Dysautonomia in chronic fatigue syndrome: facts, hypotheses, implications.

The diagnosis of chronic fatigue syndrome (CFS) is based on patient history and treatment on cognitive behavior therapy and graded exercise. There is increasing evidence that dysautonomia occurs in CFS manifest primarily as disordered regulation of cardiovascular responses to stress. We impart our experience relating to diagnosis, monitoring, and treatment of CFS based on identification and management of dysautonomia. Recently proposed methods for assessment of the cardiovascular reactivity, the 'hemodynamic instability score' (HIS) and the 'Fractal and Recurrence Analysis-based Score' (FRAS), served for this purpose. On HUTT, a particular dysautonomia is revealed in CFS patients that differ from dysautonomia in several other disorders. This distinct abnormality in CFS can be identified by HIS >-0.98 (sensitivity 84.5% and specificity 85.1%) and FRAS > +0.22 (sensitivity 70% and specificity 88%). Therefore, the HIS and FRAS may be used, in the appropriate clinical context, to support the diagnosis of CFS, which until now, could only be subjectively inferred. A pilot study suggested that midodrine treatment, directed at the autonomic nervous system in CFS, results first in correction of dysautonomia followed by improvement of fatigue. This finding implies that dysautonomia is pivotal in the pathophysiology CFS, at least in a large part of the patients, and that manipulating the autonomic nervous system may be effective in the treatment of CFS.

Grade of recurrent in situ and invasive carcinoma following treatment of pure ductal carcinoma in situ of the breast.

The grade of recurrent in situ and invasive carcinoma occurring after treatment of pure ductal carcinoma in situ (DCIS) has been compared with the grade of the original DCIS in 122 patients from four different centres (The Royal Marsden Hospitals, London and Sutton, 57 patients; Guy's Hospital, London, 19 patients; Nottingham City Hospital, 31 patients and The Royal Liverpool Hospital, 15 patients). The recurrent carcinoma was pure DCIS in 70 women (57%) and in 52 women (43%) invasive carcinoma was present, which was associated with an in situ element in 43. In all, 19 patients developed a second recurrence (pure DCIS in 11 and invasive with or without an in situ element in eight). The majority of invasive carcinomas followed high-grade DCIS. There was strong agreement between the grade of the original DCIS and that of the recurrent DCIS (kappa=0.679), which was the same in 95 of 113 patients (84%). The grade of the original DCIS showed only fair agreement with the grade of recurrent invasive carcinoma (kappa=0.241), although agreement was stronger with the pleomorphism score of the recurrent carcinoma (kappa=0.396). There was moderate agreement, in recurrent invasive lesions, between the grade of the DCIS and that of the associated invasive element (kappa=0.515). Other features that showed moderate or strong agreement between the original and recurrent DCIS were necrosis and periductal inflammation. The similarity between the histological findings of the original and subsequent DCIS is consistent with the concept that recurrent lesions represent regrowth of residual carcinoma. In addition, although agreement between the grade of the original DCIS and that of any subsequent invasive carcinoma was only fair, there is no suggestion that low-grade DCIS lesions progress to higher grade lesions or to the development of higher grade invasive carcinoma. This is in agreement with immunohistochemical and molecular data indicating that low-grade and high-grade mammary carcinomas are quite different lesions.

Responses to Bortner's scale and the eight basic emotions by patients with acute coronary heart disease at hospital admission and discharge.

We examined the prevalence of Type A behavior indicated on Bortner's scale and the Emotion Profiles of Plutchik in 190 patients, 134 men and 56 women (M age = 50 yr., SD = 9) with acute coronary heart disease at hospital admission and discharge. Type A classification was significantly more common for patients with acute coronary heart disease (75.5% versus 65%) than for the control group. Patients with acute coronary heart disease scored lower on Distrust and Dyscontrolled than the control group. Patients with unstable angina had significantly higher mean scores on Bortner's scale than patients with acute myocardial infarction and recurrent myocardial infarction at hospital discharge. Patients with recurrent myocardial infarction scored lower on Distrust and higher on Timid than patients with unstable angina at hospital admission and discharge. This research suggests that Type A behavior and some emotions are associated with acute coronary heart disease. There was a difference in scores on the Emotions Profiles and scores on Type A behavior in relation to type of acute coronary heart disease. The addition of counseling for Type A behavior to standard cardiac counseling was suggested for reduction in scores on Type A behavior.

Correlation between morphometrical parameters and disease-free survival in ductal breast cancer treated only by surgery.

A combination of quantitatively evaluated morphological parameters and of conventional prognostic indicators has been used to study 19 cases of invasive ductal breast carcinoma from patients treated only by surgery, later developing recurrences or metastases. This set of patients not treated with adjuvant therapy (radiotherapy, cytostatic or hormonal therapy), was selected from 350 consecutive breast cancers which had been treated with surgical therapy. The aim was to investigate whether the morphometrical features are correlated with disease-free survival. Of the single features, the mitotic activity index (MAI) is most strongly correlated with prognosis. Ten of the 19 patients had an MAI value above 9, and all of them recurred within 18 months. In contrast, of the 9 other patients with low mitotic rate (MAI below or equal to 9), none recurred within 24 months. Further, a correlation exists between disease-free survival, mean and standard deviation of nuclear and nucleolar area, and tubular component of the tumors. There is no correlation between nuclear form factors and recurrence. The multivariate prognostic score is also significantly correlated with recurrence, but not as strongly as in other publications. This is obviously due to the blurring influence of the lymph node status, which was not significantly correlated with the prognosis. Thus, in this small set of patients not treated with any adjuvant therapy, the results of morphometric analysis are in agreement with earlier data and emphasize the prognostic significance of quantitative microscopical analysis in breast cancer.

A comparison of one year of episodic or suppressive treatment of recurrent genital herpes with valacyclovir.

OBJECTIVES: We conducted this study to compare episodic and suppressive therapy for genital herpes about disease characteristics, disease burden, and psychologic impact. STUDY DESIGN: The authors conducted a randomized, open-label, 1-year treatment trial. RESULTS: Forty subjects were randomized to episodic therapy with valacyclovir (500 mg twice daily for 5 days) and 40 to suppressive therapy (500 mg daily). Subjects in the episodic arm experienced more outbreaks (7.87 +/- 4.65) than those in the suppressive arm (1.59 +/- 1.93) (P <0.001). Subjects in the episodic arm also had significantly more days with pain and lesions (6.5 +/- 7.3) than those in the suppressive arm (1.1 +/- 3.3) (P < 0.001), and other quantitative measures of disease burden also favored the suppressive arm. Both treatment groups had significant improvements in their recurrent genital herpes quality-of-life scores from baseline that persisted throughout the study; however, there was no significant difference between the treatment arms in these scores. CONCLUSIONS: Suppressive therapy of recurrent genital herpes with valacyclovir has a greater impact on measures of disease frequency and burden than episodic therapy. However, both treatment strategies lead to significant improvements in recurrent genital herpes quality-of-life scores. Both treatment strategies benefit patients with recurrent genital herpes.

Review article: Crohn's disease: monitoring disease activity.

A global measurement of Crohn's disease activity, comprising clinical, endoscopic, biochemical and pathological features is not available yet and perhaps is unobtainable. In this review we analyse the most used and validated clinical indices (Crohn's Disease Activity Index [CDAI], Perianal Disease Activity Index [PDAI], fistula drainage assessment), quality of life scores (Inflammatory Bowel Disease Questionnaire [IBDQ]), sub-clinical markers (C-reactive protein, faecal calprotectin, intestinal permeability) and endoscopic indices (Crohn's Disease Endoscopic Index of Severity [CDEIS]/Simple Endoscopic Score for Crohn's Disease [SES-CD], Rutgeeerts' score for postsurgical recurrence). We also review the main advantages and disadvantages of each of these scoring systems. All these indices are rather complex and time-consuming, therefore their use is limited to clinical trials. In everyday clinical practice most gastroenterologists rely on their global clinical judgement, which is less reproducible, but simpler for decision-making.

Reduction in thrombus extension and clinical end points in patients after initial treatment for deep vein thrombosis with the fixed-dose body weight-independent low molecular weight heparin certoparin.

Low molecular weight heparin (LMWH) is effective in the treatment of acute deep vein thrombosis (DVT) in adults. This has not been demonstrated for one LMWH alone. The relationship between venographic changes due to LMWH therapy and clinical outcome in the initial treatment period has not been reported. A pooled analysis of two clinical trials was performed. The trials compared a fixed-dose, body weight-independent, subcutaneous LMWH, certoparin (8000 antifactor Xa [aXa] U twice a day [b.i.d.]), with an adjusted-dose intravenous unfractionated heparin (UFH) with respect to venographic changes expressed as Marder score and occurrence of recurrent venous thromboembolism, major bleeding, and mortality. The Marder score was 23.2 +/- 8.4 in patients randomized to LMWH (n = 299 paired phlebograms) and 23.9 +/- 8.9 in patients allocated to UFH (n = 297 paired phlebograms) at entry (2p = 0.23) and 18.9 +/- 9.7 and 20.5 +/- 9.9 at the end of the initial therapy (2p = 0.04), respectively. The composite outcome of recurrent venous thromboembolism, major bleeding, and mortality occurred less frequently during treatment with LMWH (n = 393) than it did with UFH (n = 404, 1.3% versus 5.0%, risk reduction [RR] 0.26, 95% confidence interval [CI] 0.11 to 0.63, 2p = 0.004). Single events of recurrent thromboembolism (2p = 0.12), major bleeding (2p = 0.03), and mortality (2p = 0.12) were observed less frequently with LMWH. A trend toward a lack of regression of thrombus size was observed in recurrent venous thromboembolism (2p = 0.08). Body weight-independent LMWH significantly reduces thrombus size and the incidence of composite outcome during the initial treatment of acute proximal venous thrombosis compared with adjusted dose intravenous UFH. The data indicate a relation between an unimproved Marder score and a recurrent venous thromboembolism.

A clinicopathologic study of 81 patients with ependymomas and proposal of diagnostic criteria for anaplastic ependymoma.

Optimal histologic criteria for the classification of and grading of ependymomas, including their anaplastic forms, remain elusive. This is especially true because of the poor correlation of these criteria with clinical outcome. The aim of this study was to identify the histopathologic parameters that could distinguish different prognostic groups of patients with ependymomas. Eighty-one patients with ependymal tumors, including those originally diagnosed ependymomas, anaplastic ependymomas and myxopapillary ependymomas, were enrolled in this study. Thirteen histologic parameters, including hypercellularity, nuclear pleomorphism, mitoses, endothelial proliferation, necrosis, clear cell, thrombi, dystrophic calcification, psammoma bodies, bone, cartilage, Rosenthal fibers and MIB-1 labeling index (LI), were evaluated in each patient and correlated with clinical outcome. We assigned one score for each histopathologic parameter evaluated and used a stepwise selection method with entry model based on the significance of the log-rank statistic to formulate a scoring model. Four parameters were chosen in this process, including mitoses > or = 4/10 hpf (1.7/mm2), hypercellularity, endothelial proliferation and necrosis. The sum of these four parameters (scores) was the histopathologic score of the tumor. The progression-free survival (PFS) and overall survival (OS) of patients with histopathologic scores 0 and 1 were significantly better than those with histopathologic scores 2, 3 and 4 (p < 0.001 and p = 0.005, respectively). Because of the latter finding, we proposed that anaplastic ependymoma could be diagnosed by the presence of any two of the aforementioned four parameters. Multivariate analyses including clinical and histopathologic variables showed that histopathologic score > or = 2 and subtotal resection were the factors related to increased risk of recurrence, while histopathologic score > or = 2 was the only factor related to overall survival. Based on the above findings, we concluded that histopathology is an important prognostic indicator for patients with ependymomas.

Probability of biochemical recurrence by analysis of pathologic stage, Gleason score, and margin status for localized prostate cancer.

OBJECTIVES: The Partin tables provide pretreatment information regarding the probability of various pathologic stages (eg, organ confined, extraprostatic extension, and seminal vesicle or lymph node involvement). Although the pathologic stage serves as an excellent surrogate for outcome after radical prostatectomy (RRP), many patients and physicians want to know how the predictions made from the Partin tables can be translated into long-term biochemical recurrence-free survival. In this work, we go beyond the pathologic outcomes predicted by the Partin nomograms to provide long-term biochemical recurrence-free estimates on the basis of the pathologic data obtained at RRP to help counsel patients after surgery for prostate cancer. METHODS: The study group comprised 1955 men treated by one surgeon with RRP and pelvic lymph node dissection for clinically localized disease (1989 to 2001). The patients were followed up for at least 1 year postoperatively, and the disease-free survival rates were determined using Kaplan-Meier analysis. RESULTS: The pathologic stages were as follows: organ confined in 57%, extraprostatic extension in 35%, seminal vesicle involvement in 4%, and lymph node involvement in 4%. The prostatectomy Gleason score distribution was as follows: 2 to 4 in 1%, 5 to 6 in 63%, 7 in 30%, and 8 to 10 in 6%. Overall, a positive surgical margin was present in 9.8%. On the basis of the prostatectomy Gleason score, pathologic stage, and surgical margin status, the probability of long-term biochemical recurrence-free survival was divided into four groups: excellent, good, moderate, and low. CONCLUSIONS: These simple to use and explain risk groups can be used to predict long-term biochemical recurrence-free survival from pathologic stage data obtained at surgery or predicted from the Partin tables, along with surgical margin status and Gleason score information obtained at RRP.

Outcomes after minimally invasive esophagomyotomy.

BACKGROUND: Thoracic surgeons traditionally performed thoracotomy and myotomy for achalasia. Recently minimally invasive approaches have been reported with good success. This report summarizes our single-institution experience using video-assisted thoracoscopy (VATS) or laparoscopy (LAP) for the treatment of achalasia. METHODS: A review of 62 patients undergoing minimally invasive myotomy for achalasia was performed. There were 27 male and 35 female patients. Mean age was 53 years (range 14 to 86). Thirty-seven (59.7%) had failed prior treatments (balloon dilation, botulinim toxin injection, or prior surgery). Outcomes studied were dysphagia score (1 = none, 5 = severe), Short-Form 36 quality of life (SF36 QOL) score, and heartburn-related QOL index (HRQOL). RESULTS: Surgery included myotomy and partial fundoplication (5 VATS and 57 LAP). Mortality was zero, and complications occurred in 9 (14.5%) patients. There were 6 perforations (4 repaired by LAP and 2 open). Median length of stay was 2 days, time to oral intake was 1 day. At a mean of 19 months follow-up, 92.5% of patients were satisfied with outcome. Dysphagia scores improved from 3.6 to 1.5 (p < 0.01) but 3 patients ultimately required esophagectomy for recurrent dysphagia. HRQOL scores for heartburn and SF-36 QOL scores were comparable with control populations. CONCLUSIONS: Minimally invasive myotomy and partial fundoplication for achalasia improved dysphagia in 92.5% of patients with heartburn and QOL scores were comparable with normal values at 19-month follow-up. The laparoscopic approach offers excellent results and was the preferred approach by our thoracic group for treating achalasia. Thoracic residency training should strive to include laparoscopic esophageal experience.

Factors affecting recurrence rates after prostatectomy or radiotherapy in localized prostate carcinoma patients with biopsy Gleason score 8 or above.

BACKGROUND: To review the biochemical recurrence-free survival (bRFS) rates of treatment with either external beam radiotherapy or radical prostatectomy in patients with biopsy Gleason score 8 or above in the prostate specific antigen (PSA) era. METHODS: A total of 297 localized prostate carcinoma patients diagnosed with biopsy Gleason score 8 or above were treated between 1987 and 2000 at the Cleveland Clinic with either prostatectomy or radiotherapy (RT). All patients had pretreatment PSA (iPSA) levels. Androgen deprivation was given as part of the initial treatment in 154 patients (52%). Radical prostatectomy (RP) was the primary treatment in 115 patients (39%) and 182 patients (61%) received RT. The median radiation dose was 70.2 Gy (range, 60.0-78.0 Gy). The median follow-up time was 42 months (range, 1-153 months). RESULTS: For the 297 patients, the 5 and 8-year bRFS rates were 45% (95% confidence interval [CI] 38-52%) and 31% (95% CI 20-42%), respectively. The 5-year bRFS rates for iPSA 10 or less versus. iPSA above10 were 66% (95% CI 54-78%) versus 31% (95% CI 22-40%), respectively (P < 0.001). The 5-year bRFS rates for use of androgen deprivation versus no androgen deprivation were 62% (95% CI 52-72%) versus 35% (95% CI 27-42%), respectively (P < 0.001). The 5-year bRFS rates for RT patients versus RP patients were 47% (95% CI 38-57%) versus 42% (95% CI 31-53%), respectively (P = 0.051). For RT patients, the 5-year bRFS rates for use of androgen deprivation versus no androgen deprivation were 71% versus 29%, respectively (P < 0.001). For RP patients, the 5-year bRFS rates for use of androgen deprivation versus no androgen deprivation were 39% versus 43%, respectively (P = 0.90). Multivariate time-to-failure analysis using the proportional hazards model showed iPSA level (P < 0.001) and the use of androgen deprivation (P = 0.001) to be the only independent predictors of biochemical recurrence. Age (P = 0.44), race (P = 0.80), clinical T stage (P = 0.10), biopsy Gleason scores (P = 0.39), and treatment modality (P = 0.13) were not independent predictors of biochemical failure. A total of 104 patients had Stage T1 or T2 disease, low iPSA levels (</= 10 ng/mL), and a high Gleason score (>/= 8). For all 104 patients, the 5-year bRFS rate was 64%. For 52 of the 104 patients who received 6 months of androgen deprivation or less, the 5-year bRFS rate was 78%. CONCLUSION: Patients with localized prostate carcinoma with a biopsy Gleason score 8 or less have lower recurrence rates if iPSA levels are 10 or less. Biochemical control rates were encouraging for patients with biopsy Gleason score 8 or above, clinical Stage T1-T2, and iPSA levels less than or equal to 10 ng/mL treated with adjuvant androgen deprivation given only for 6 months or less. If longer follow-up confirms these findings, these patients might not need prolonged androgen deprivation for periods exceeding 6 months following local therapy.

Needle biopsy of recurrent adenocarcinoma of the prostate after radical prostatectomy.

The objective of this study was to evaluate needle biopsy of recurrent prostate cancer after radical prostatectomy. We evaluated 37 cases of recurrent prostate cancer after radical prostatectomy that were diagnosed by needle biopsy between March 1984 and July 1998. Fifteen were from consultations in which contributors were uncertain of the diagnosis, and 22 were from men who had come to The Johns Hopkins Hospital for treatment. The median interval from radical prostatectomy to biopsy showing recurrent tumor was 40 months. There was no correlation between the interval to recurrence and either pathologic features of the biopsy and radical prostatectomy or various clinical features. The mean extent of adenocarcinoma in the biopsies was 3.2 mm (range, 0.1 to 18 mm; median, 2 mm). The length of recurrent cancer on biopsy correlated with an abnormal rectal examination (P = .001). The mean Gleason score for the recurrent tumors was 6.5, which correlated with the grade of the radical prostatectomy cancer (P = .005). The cancers often lacked overt histologic features of malignancy. Benign prostatic acini were seen in five cases (14%), usually separate from the cancer. In 5 (33%) of the consultation cases, we would not have been able to diagnose cancer if not for the fact that atypical prostate glands should not be present after radical prostatectomy. In well-sampled radical prostatectomies, margins were almost always positive, as was extraprostatic extension. In cases with less sampling, there was a higher incidence of organ-confined disease and margin-negative disease implying suboptimal processing of the radical prostatectomy. After radical prostatectomy, recurrent cancer on needle biopsies may be focal and difficult to diagnose and must be assessed differently than in patients who have not had surgery.

[Azathioprine and 5-ASA in the prevention of postoperative recurrence of Crohn's disease].

Recurrence of Crohn's disease (CD) lesions in the neo-ileum after apparently curative resection frequently occurs after surgery. The most appropriate prophylactic treatment has not been clearly defined. This study evaluated the efficacy of 5-ASA and azathioprine in decreasing postoperative recurrence and analysed the presence of variables associated with recurrence. Thirty-nine patients (mean age 32.8 years, range 18-61) with a history of ileal or ileocecal surgical resection were studied. They received 5-ASA (3 mg/day) or azathioprine (50 mg/day) immediately after the operation and for 2 years thereafter. Patients were followed clinically (Crohn's disease activity index) and serologically every 3 months and by imaging methods every 6 months. The latter included colonoscopy with ileoscopy and if not available, small bowel barium or ultrasonographic study. Laboratory tests included ESR, C-reactive protein, white blood cell and platelet count, fibrinogen and albumin. The end-point evaluated included clinical recurrence (CR), serological recurrence (SR: alteration of at least three of the above-mentioned variables) and morphologic recurrence (MR: endoscopic recurrence > 1 according to Rutgeerts score or radiological or ultrasonographic recurrence). Eighteen patients received azathioprine and 21 received 5-ASA. Thirty-four patients were evaluated. The cumulative proportion of patients with recurrence was 29% (CR), 35% (SR) and 50% (MR). Statistical analysis did not show significant differences between the two groups. Twenty-seven patients completed the 2-year study (11 in the azathioprine group and 16 in the 5-ASA group). Crude relapse rates were 37% (CR), 44% (SR) and 69% (MR) in the 5-ASA group and 36% (CR), 45% (SR) and 64% (MR) in the azathioprine group. No statistically significant differences were observed between groups. No variables associated with recurrence were detected. In conclusion, treatment does not prevent a high percentage of postsurgical recurrence. 5-ASA (3 g/day) and azathioprine (50 mg/day) showed similar efficacy in the prevention of recurrence.
