Recurrent varicose veins after surgery: a new appraisal of a common and complex problem in vascular surgery.

OBJECTIVE: To assess the true incidence, the reflux patterns and the mechanisms responsible for recurrent varicose vein disease according to current definitions and guidelines. PATIENTS AND METHODS: Ninety-three patients (69 female, 24 male, mean age: 48 years) were prospectively evaluated pre- and postoperatively (1 month and 5 years), using clinical and colour duplex examination of both lower limbs. The CEAP score and its modification for recurrence (REVAS) were used for classification. RESULTS: In 113 operated lower limbs, 28 (25%) were found to have a recurrence, 20 of which were symptomatic (20/28, 72%). However, in this group, the mean severity score decreased significantly from 6.5 (SD 3.1) to 5.2 (SD 2.8) (p<0.001, paired t-test). The correlation between the type and cause of recurrence revealed: (1) true recurrent varices in eight limbs (8/28, 29%), primarily caused by neovascularisation, (2) new varicose veins as a consequence of disease progression in seven limbs (7/28, 25%), (3) residual veins in three limbs (3/28, 11%) mainly due to tactical errors (e.g. failure to strip the GSV), (4) complex patterns in 10 limbs (10/28, 36%). In the limbs with recurrence, 42 sources of venous reflux were identified: (1) 19 new sites of venous reflux were due to disease progression (15% of the operated limbs), (2) 13 were caused by neovascularisation (11.5% of the operated limbs), (3) six resulted from tactical failures (5.3% of the operated limbs) and (4) four were due to technical failures (3.5% of the operated limbs). CONCLUSIONS: This study shows that the recurrence of varicose veins after surgery is not uncommon. However, the clinical condition of most affected limbs remains improved. Progression of the disease and neovascularisation are responsible for more than half of the recurrences. Rigorous evaluation of patients and assiduous surgical technique might reduce recurrence due to technical and tactical failures.

Lack of association of prostate carcinoma nuclear grading with prostate specific antigen recurrence after radical prostatectomy.

PURPOSE: Grading prostate cancer using the Gleason system relies only on architectural tumor growth, in contrast to other systems, such as the WHO system, which grade prostate carcinoma based on nuclear features as well as architectural patterns. The prognostic significance of nuclear grading remains controversial since most studies were performed before prostate specific antigen (PSA) screening became widely available. We evaluated the significance of nuclear grade for predicting PSA recurrence in a contemporary cohort of patients treated with radical prostatectomy for clinically localized prostate carcinoma. MATERIALS AND METHODS: Nuclear grades 1 to 3 were determined in 141 consecutive radical prostatectomies in 1995. Predominant and worst nuclear grade was determined by a consensus of 3 pathologists. Statistical analysis compared nuclear grade with Gleason score using the chi-square test. The Cox proportional hazards analysis was performed to calculate the ability of nuclear grade, Gleason score and other variables to predict PSA recurrence. RESULTS: We identified a significant association of Gleason score with worst nuclear grade (p = 0.007). All 6 cases with a Gleason score of 8 or greater had a worst nuclear grade of 3, in contrast to 36 of 60 (60%) with a score 6 or less, in which the worst nuclear grade was 3. Of the 141 patients 31 (21.9%) had PSA recurrence at a median followup of 3.7 years. The univariate Cox model revealed significant associations of PSA recurrence with Gleason score 8 or greater (hazards ratio 5.5, p = 0.005), extraprostatic extension (hazards ratio 3.4, p = 0.001), positive surgical margin (hazards ratio 2.6, p = 0.009), seminal vesicle involvement (hazards ratio 7.3, p <0.001), preoperative serum PSA (hazards ratio 1.03, p = 0.007), tumor stage (hazards ratio 3.6, p = 0.001) and maximal tumor dimension (hazards ratio 2.4, p <0.001). However, overall and worst nuclear grade did not predict PSA recurrence (p = 0.89 and 0.13, respectively). Nuclear grade did not fit any multivariate model tested, which otherwise included Gleason score, log(PSA), surgical margin status, extraprostatic extension, seminal vesicle status, tumor size and pathological stage. By varying sample fixation time we also showed that benign prostate tissue in the same section as prostate carcinoma had grade 2 or 3 nuclear changes, that is moderate to marked anaplasia. CONCLUSIONS: High nuclear grade is associated with high Gleason score. However, prostate carcinoma with a Gleason score of 6 or less shows extreme variability. Nuclear grade determined by light microscopy failed to predict PSA recurrence in a contemporary series of men with clinically localized prostate cancer treated with radical prostatectomy. Nuclear morphology is subject to tissue fixation and processing artifact. Any nuclear morphometric study must consider this artifact.

Patient selection for salvage cryotherapy for locally recurrent prostate cancer after radiation therapy.

PURPOSE: Our objective was to identify clinical pretreatment factors associated with early treatment failure after salvage cryotherapy. PATIENTS AND METHODS: Between 1992 and 1995, 145 patients underwent salvage cryotherapy for locally recurrent adenocarcinoma of the prostate. Treatment failure was defined as an increasing postcryotherapy serial prostate-specific antigen (PSA) level of more than or equal to 2 ng/mL above the postcryotherapy nadir or as a positive posttreatment biopsy. We evaluated the following factors as predictors of treatment failure: tumor stage and grade at initial diagnosis, type of prior therapy, stage and grade of locally recurrent tumor, number of positive biopsy cores at recurrence, and precryotherapy PSA level. RESULTS: Among patients with a prior history of radiation therapy only, the 2-year actuarial disease-free survival (DFS) rates were 74% for patients with a precryotherapy PSA less than 10 ng/mL and 28% for patients with a precryotherapy PSA more than 10 ng/mL, P <.00001. The DFS rates were 58% for patients with a Gleason score of less than or equal to 8 recurrence and 29% for patients with a Gleason score greater than or equal to 9 recurrence, P <.004. Among patients with a precryotherapy PSA less than 10 ng/mL, DFS rates were 74% for patients with a prior history of radiation therapy only and 19% for patients with a history of prior hormonal therapy plus radiation therapy, P <.002. CONCLUSION: Patients failing initial radiation therapy with a PSA more than 10 ng/mL and Gleason score of the recurrent cancer more than or equal to 9 are unlikely to be successfully salvaged. Patients failing initial hormonal therapy and radiation therapy are less likely to be successfully salvaged than patients failing radiation therapy only.

Prostate cancer in patients with screening serum prostate specific antigen values less than 4.0 ng/dl: results from the cooperative prostate cancer tissue resource.

PURPOSE: Prostate cancer can occur in patients with low screening serum prostate specific antigen (PSA) values (less than 4.0 ng/ml). It is currently unclear whether these tumors are different from prostate cancer in patients with high PSA levels (greater than 4.0 ng/ml). MATERIALS AND METHODS: From the Cooperative Prostate Cancer Tissue Resource database through March 2004, 3,416 patients with screening PSA less than 16.0 ng/ml diagnosed with prostate cancer between 1993 and 2004 were stratified in groups based on screening serum PSA. These subsets were compared for race, age at diagnosis, clinical and pathological stage, Gleason score, positive surgical margins, posttreatment recurrent disease, and vital status. RESULTS: We identified 468 (14%) patients with screening PSA less than 4.0 ng/ml, 142 (4.2%) of whom had a PSA of less than 2.0 ng/ml. This group included 40 black and 376 white patients. Men with low screening PSA treated with radical prostatectomy had smaller cancers, lower Gleason scores, lower pathological tumor (T) stage and lower PSA recurrence rates than men with high PSA levels (4 ng/ml or greater). These differences held true for men who were younger than 62 years or were white, whereas older or black men had tumor characteristics and outcomes similar to those with higher PSA levels. CONCLUSIONS: Young (younger than 62 years) or white patients with screening serum PSA less than 4.0 ng/ml had smaller, lower grade tumors and lower recurrence rates than patients with PSA 4.0 ng/ml or greater. This was not true for those older than 62 years and for black men.

Recurrent Pseudomonas aeruginosa pneumonia in an intensive care unit.

We reviewed the records of all patients in the intensive care unit (ICU) who had Pseudomonas aeruginosa pneumonia over a 2.5-year period. Of patients with P aeruginosa pneumonia, 20 of 34 survived the initial episode of pneumonia. Ten of these 20 developed recurrence. In the nonrecurrent group, nine of ten survived hospitalization, compared to only four of ten in the recurrent group. Comparing the recurrent to the nonrecurrent group, factors associated with recurrence were the APACHE 2 score (12.3 +/- 2.7 vs 8.6 +/- 4.2 [p less than 0.03]), APS score (7.0 +/- 3.5 vs 2.7 +/- 2.1 [p less than 0.01]), and chronic pulmonary disease (8/10 vs 2/10 [p less than 0.05]). The recurrent P aeruginosa group was younger (63 +/- 10 vs 74 +/- 11 years old [p less than 0.03]) and spent more time receiving mechanical ventilation (95 +/- 64 vs 26 +/- 36 days [p less than 0.01]), in the ICU (101 +/- 61 vs 33 +/- 35 days [p less than 0.01]), and in the hospital (144 +/- 77 vs 84 +/- 32 days [p less than 0.03]). Although not statistically significant, in the recurrent group, eight of ten patients had tracheostomy and seven of ten had COPD, vs three of ten and two of ten, respectively, in the nonrecurrent group. Recurrent P aeruginosa pneumonia in the ICU is associated with increased morbidity and mortality and does not appear to be related to the adequacy of antibiotic treatment. Chronic lung disease appears to predispose patients to recurrent P aeruginosa pneumonia.

Modified CLIP using PIVKA-II for evaluating prognosis after hepatectomy for hepatocellular carcinoma.

AIMS: The new staging system proposed by the Cancer of the Liver Italian Program (CLIP) for hepatocellular carcinoma (HCC) accounts for both liver dysfunction and tumour characteristics. The present study was designed to analyze UICC TNM stage, CLIP and modified CLIP in 91 patients who underwent hepatic resection for HCC. METHODS: In the modified CLIP, scoring of AFP was replaced by that of protein induced by vitamin K absence or antagonist II (PIVKA-II; predictive value, > or = 400 mAU/ml). RESULTS: After hepatic resection, 54 patients developed recurrent tumours. High PIVKA-II was a significant determinant of recurrence (p<0.05). However, a high score of the modified CLIP as well as those other staging systems did not correlate with tumour-recurrence rate. Univariate analysis showed that high TNM score, CLIP score and our modified CLIP score were significant predictors of poor prognosis. Multivariate Cox's analysis revealed that high PIVKA-II and high modified CLIP score were associated with higher risk for disease-free and overall survival as well as high TNM stage. CONCLUSIONS: Compared with the original CLIP, our modified CLIP was a better predictor of prognosis of HCC patients who underwent hepatic resection.

Gamma knife radiosurgery for trigeminal neuralgia.

OBJECTIVE: The purpose of this study was to assess outcomes in patients treated with gamma knife radiosurgery for trigeminal neuralgia. METHODS: From 1997 to 2003, a total of 49 patients with trigeminal neuralgia underwent gamma knife radiosurgery. The trigeminal root entry zone immediately adjacent to the pons was targeted by use of a 4-mm collimator to deliver 40 Gy to the 50% isodose line (maximum dose, 80 Gy). Special care was taken to limit radiation dose to the adjacent pons to 12 Gy. Of the 49 study patients, all had undergone previous medical therapy, 8 (16%) had undergone microvascular decompression, 8 (16%) had undergone percutaneous rhizotomy, 2 (4%) had undergone linear accelerator-based radiosurgery, and 5 (10%) presented with multiple sclerosis. The median duration of symptoms was 6 years. There were 29 female patients (59%) and 20 male patients (41%). Facial pain outcomes were assessed by use of the Barrow Neurological Institute pain score. Other outcomes assessed included recurrence of symptoms and treatment toxicity. The median follow-up period was 49 months. RESULTS: At last evaluation, a total of 27 patients (61%) with idiopathic trigeminal neuralgia reported pain relief (scores of IIIb or less). This included 14 patients (32%) who reported complete pain relief when not receiving medications. Significant recurrence of pain after an initial interval of relief was reported by 10 patients (23%). Mean time to pain recurrence was 9.6 months (range, 2-36 mo). Mild to moderate facial numbness was experienced by 13 patients (29%), whereas 8 (18%) reported mild dysesthesias. CONCLUSION: Gamma knife radiosurgery established durable pain relief in 61% of patients with medically refractory idiopathic trigeminal neuralgia. A longer follow-up period is necessary to fully assess the incidence of late complications and recurrences.

The role of surgery in ovarian cancer with special emphasis on cytoreductive surgery for recurrence.

PURPOSE OF REVIEW: The role of cytoreductive surgery for recurrent ovarian cancer has not clearly been defined, and randomized trials are lacking. Some series have reported favorable outcomes for selected patients. This review summarizes the available evidence for selecting patients and the results of cytoreductive surgery in recurrent ovarian cancer. RECENT FINDINGS: A Medline search identified 23 series including 1795 patients (21-285 patients per study). Patients who underwent cytoreductive surgery for recurrence were highly selected. Complete tumor resection was feasible in 9 to 82% of patients and was commonly associated with prolonged survival. A variety of predictive and prognostic factors for complete resection were reported. Good performance status, disease characteristics (e.g. peritoneal carcinosis), and outcome of prior surgery seemed to have an impact on surgical outcome. By contrast, disease-free survival played only a minor role, especially in patients with recurrence later than 6 months after primary treatment. SUMMARY: Prospective evaluation of predictive scores for successful cytoreductive surgery in recurrent ovarian cancer is urgently needed. In a second step, randomized trials evaluating the role of surgery in the treatment strategy of recurrent ovarian cancer should be initiated. Until then, experienced and trained surgeons might offer surgery for recurrent disease to individually selected patients after giving information about the potential benefit and about the limited available evidence regarding this strategy.

Is there a progression of histologic grade from radical prostatectomy to local recurrence in patients with clinically isolated local recurrence following surgery?

OBJECTIVE: To evaluate whether there is any histologic progression from radical prostatectomy (RP) to local recurrence in patients with clinically isolated local recurrence following RP. METHODS AND MATERIALS: A total of 43 patients with clinically isolated, biopsy proven, local recurrence following RP were retrospectively analyzed with respect to the change in Gleason score (GS) from RP to local recurrence. Central pathology review was undertaken for both RP and local recurrence biopsy specimens. The changes in primary and secondary Gleason grade (GG), and any potential correlation between the extent of GS change and other variables were also examined. RESULTS: Median age at the time of local recurrence was 67 years (range: 55-78). Median interval between RP and local recurrence was 3.6 years (range: 0.3-17.7). Eight had a short course (<3 months) of hormone therapy prior to RP. Initial GS of RP specimens was 5, 6, 7, 8, and 9 in 1, 3, 29, 1, and 9 patients, respectively. At the time of local recurrence, GS was upgraded in 13, unchanged in 23, and downgraded in 7. The extent of GS change was correlated with the interval between RP and local recurrence, but not with pathological T stage or age. CONCLUSION: There was no statistically significant change in GS from RP to local recurrence, although there was a trend toward a higher GS at the time of local recurrence. The extent of GS change was associated positively with the elapsed time to local recurrence.

Therapy monitoring of presacral recurrences after high-dose irradiation: value of PET, CT, CEA and pain score.

21 patients were followed by positron-emission-tomography (PET) FDG (18Flourdeoxyglucose) uptake, physical examination, CT and CEA levels after combined photon-neutron irradiation for inoperable recurrent rectal carcinoma. In order to evaluate the response to radiotherapy symptomatic relief, CEA levels, decrease of tumor volume measured by CT analysis were correlated with the FDG-uptake. The objective of this study was also to investigate if the level of FDG-uptake prior to radiotherapy or the early decrease after therapy can be used as a prognostic factor. Prior to radiotherapy sacral pain was the predominant symptom. All malignancies showed measurable tumor masses, evaluation of CEA levels and enhanced tracer accumulation of FDG in the PET cross section. The mean FDG-uptake before radiotherapy was 2.3 +/- 1.1 (range 1.1 to 5.0) in 21 patients in contrast to 1.9 +/- 0.7 (range 0.8 bis 4.0) three months after radiotherapy. In six patients FDG concentration values decreased to the range of normal soft tissue, moreover, two of them relapsed after six and 22 months. Elevated FDG-uptake of the sacral bone was noted in PET cross sections in two patients, while there was no evidence of osseous alterations in CT. Normal levels of CEA were achieved in 14 patients and complete or partial pain relief in 20 of 21 patients. A decrease of tumor volume of more than 50% was detected in the follow-up CT scans of three patients but no complete remission was found. The result suggests that enhanced glucose uptake is associated with recurrent rectal cancer. However, enhanced glycolytic activity is related not only to malignant cells but also to all proliferating cells. To distinguish between proliferation, repair, inflammation, and residual viable tumor cells is not possible and may be responsible for an unchanged or elevated FDG-uptake after radiotherapy.

Defaecation disorders in children, colonic transit time versus the Barr-score.

It is still unclear how to evaluate the existence of faecal retention or impaction in children with defaecation disorders. To objectivate the presence and degree of constipation we measured segmental and total colonic transit times (CTT) using radio-opaque markers in 211 constipated children. On clinical grounds, patients (median age 8 years (5-14 years)) could be divided into three groups; constipation, isolated encopresis/soiling and recurrent abdominal pain. Barr-scores, a method for assessment of stool retention using plain abdominal radiographs, were obtained in the first 101 patients, for comparison with CTT measurements as to the clinical outcome. Of the children with constipation, 48% showed significantly prolonged total and segmental CTT. Surprisingly, 91% and 91%, respectively, of the encopresis/soiling and recurrent abdominal pain children had a total CTT within normal limits, suggesting that no motility disorder was present. Prolonged CTT through all segments, known as colonic inertia, was found in the constipation group only. Based on significant differences in clinical presentation, CTT and colonic transit patterns, encopresis/soiling children formed a separate entity among children with defaecation disorders, compared to children with constipation. Recurrent abdominal pain in children was in the great majority, not related to constipation. Barr-scores were poorly reproducible, with low inter- and intra-observer reliability. This is the first study which shows that clinical differences in constipated children are associated with different colonic transit patterns. The usefulness of CTT measurements lies in the objectivation of complaints and the discrimination of certain transit patterns. Conclusion. Abdominal radiographs, even when assessed with the Barr-score proved unreliable in diagnosing constipation.(ABSTRACT TRUNCATED AT 250 WORDS)

Particle embolization of recurrent hepatocellular carcinoma after hepatectomy.

BACKGROUND: Complete surgical resection is the mainstay of treatment for patients with hepatocellular carcinoma (HCC). Unfortunately, most patients ultimately develop disease recurrence and the median survival from the time of recurrence is <1 year. The purpose of the current study was to review the authors' experience using bland hepatic arterial embolization to treat recurrent HCC after definitive surgical resection. METHODS: The authors reviewed their single-center hepatic embolization database from 1995 through 2004 to identify patients who underwent bland hepatic arterial embolization for disease recurrence. Data analyzed included patient demographics, Okuda stage and Child score, imaging findings, and embolization variables. Recurrence-free survival (from surgery to disease recurrence) and survival time (from recurrence to last follow-up) were calculated using the Kaplan-Meier method. RESULTS: The authors identified 45 patients treated with bland embolization for recurrent HCC after resection. Six patients also underwent ablative therapy after embolization. Of the 45 patients, 42 (93.3%) patients had Okuda Stage 1 disease. The median time to recurrence was 13 months. The median survival after embolization was 46 months, and actuarial survival rates at 1 year, 2 years, and 5 years after recurrence were 86%, 74%, and 47%, respectively, with a median follow-up of 31 months. Patients who developed disease recurrence with a solitary lesion had a significantly improved survival (P = .03) At the time of last follow-up, 3 patients (6.6%) were alive with no evidence of viable disease. CONCLUSIONS: Bland arterial embolization was found to be an effective method of salvage therapy for patients with good liver function with recurrent HCC after prior surgical resection. Patients whose disease recurred with a solitary lesion appear to have a significantly increased survival compared with patients who develop disease recurrence with multiple tumors. A small proportion of patients can be rendered without evidence of viable disease.

A prognostic index for ductal carcinoma in situ of the breast.

BACKGROUND: There is controversy and confusion regarding therapy for patients with ductal carcinoma in situ (DCIS) of the breast. The Van Nuys Prognostic Index (VNPI) was developed to aid in the complex treatment selection process. METHODS: The VNPI combines three significant predictors of local recurrence: tumor size, margin width, and pathologic classification. Scores of 1 (best) to 3 (worst) were assigned for each of the 3 predictors and then totaled to give an overall VNPI score ranging from 3 to 9. Three hundred thirty-three patients with pure DCIS treated with breast preservation (195 by excision only and 138 by excision plus radiation therapy) were studied with detection of local recurrence as the end point. RESULTS: There was no statistical difference in the 8 year local recurrence free survival in patients with VNPI scores of 3 or 4, regardless of whether or not radiation therapy was used (100% vs. 97%; P = not significant). Patients with VNPI scores of 5, 6, or 7 received a statistically significant 17% local recurrence free survival benefit when treated with radiation therapy (85% vs. 68%; P = 0.017). Patients with scores of 8 or 9, although showing the greatest relative benefit from radiation therapy, experienced local recurrence rates in excess of 60% at 8 years. CONCLUSIONS: DCIS patients with VNPI scores of 3 or 4 can be considered for treatment with excision only. Patients with intermediate scores (5, 6, or 7) show a 17% decrease in local recurrence rates with radiation therapy. Patients with VNPI scores of 8 or 9 exhibit extremely high local recurrence rates, regardless of irradiation, and should be considered for mastectomy.

Criteria for arthroscopic treatment of anterior instability of the shoulder: a prospective study.

We prospectively evaluated 61 patients treated arthroscopically for anterior instability of the shoulder at a mean follow-up of 44.5 months (24 to 100) using the Rowe scale. Those with post-operative dislocation or subluxation were considered to be failures. Logistic regression analysis was used to identify patients at increased risk of recurrence in order to develop a suitable selection system. The mean Rowe score improved from 45 pre-operatively to 86 at follow-up (p < 0.001). At least one episode of post-operative instability occurred in 11 patients (18%), although their stability improved (p = 0.018), and only three required revision. Subjectively, eight patients were dissatisfied. Age younger than 28 years, ligamentous laxity, the presence of a fracture of the glenoid rim involving more than 15% of the articular surface, and post-operative participation in contact or overhead sports were associated with a higher risk of recurrence, and scored 1, 1, 5 and 1 point, respectively. Those patients with a total score of two or more points had a relative risk of recurrence of 43% and should be treated by open surgery.

Outcome after radical prostatectomy with a pretreatment prostate biopsy Gleason score of >/=8.

OBJECTIVE: To determine the outcome and predictors of recurrence in patients with a pretreatment prostate biopsy Gleason score (GS) of >/= 8 and treated with radical prostatectomy (RP). PATIENTS AND METHODS: We retrospectively reviewed 1048 consecutive patients who underwent RP by one surgeon (M.S.S.); patients who had a pretreatment biopsy GS of >/= 8 were identified. Information was recorded on patient age, initial prostate specific antigen (PSA) level, clinical stage, biopsy GS, pathology GS, extraprostatic extension (EPE), tumour volume, surgical margin status, seminal vesicle invasion (SVI), and lymph node involvement. The results were assessed statistically using the Kaplan-Meier method, univariate log-rank tests and multivariate analysis using Cox's proportional hazards regression. RESULTS: In all, 123 patients met the initial selection criteria; 44 were excluded from further analyses (five salvage RP, 23 < 1 year follow-up and 16 adjuvant treatment). Thus 79 patients were included in the uni- and multivariate analyses; 25 (31%) patients had a GS of </= 7 in the RP specimen and 54 (69%) remained at GS >/= 8. The mean follow-up was 55 months, the age of the patients 63 years and the mean (sd) initial PSA level 13 (12) ng/mL. The overall biochemical failure rate was 38% (41% if the final GS was >/= 8 and 32% if it was </= 7). For those with a GS of >/= 8 in the RP specimen, 20% (11/54) were organ-confined; two patients (2.5%) in this group developed local recurrence. If the final GS was </= 7, 52% (13/25) were organ-confined. In the univariate analysis, significant risk factors for recurrence were PSA >/= 20 ng/mL, EPE, SVI, a positive surgical margin and tumour volume. Cox's proportional regression indicated that a PSA of >/= 20 ng/mL (hazard ratio 7.9, 95% confidence interval 2.6-24.2, P < 0.001), the presence of EPE (4.2, 1.6-10.9, P = 0.004) and a positive surgical margin (3.8, 1.5-9.7, P = 0.005) were significant independent predictors in a multivariate analysis. CONCLUSION: RP is a reasonable treatment option for patients with a prostate biopsy GS of >/=8 and clinical stage T1-2. These patients have a high chance of remaining disease-free if their PSA level is </= 20 ng/mL. Patients with a pretreatment biopsy GS of >/= 8 should be counselled about the potential differences between the biopsy and the RP specimen GS.

AgNOR staining may reflect the growth potential of pilocytic astrocytomas.

The value of AgNOR staining as a tumor biological marker was tested in 26 children with pilocytic astrocytomas (20) and fibrillary astrocytomas (6). All patients were surgically treated and then followed up by periodic MRI or CT scans. Follow-up ranged from 8 to 84 months, with a mean of 44 months. AgNOR expression was determined by using semi-automated computer-assisted surface area measurements. AgNOR values ranged from 1.4 to 81.4 microm(2) per cell, with a mean of 26.6 and a median of 15.2. The median value was taken as a "cut-off" score separating two groups of patients with low and high AgNOR scores. Of the 13 patients in the low scoring group, 8 had total resections without recurrence, 3 had stable residual tumors, 1 had regressing residual tumor after irradiation and 1 had a recurrence 5 years after neuroradiologically complete resection of a fibrillary astrocytoma. In the group with high AgNOR scores only 2 patients had total resections without recurrence; 5 had stable residual tumors and 6 had residual tumors that showed progression, all within 1 year after surgery. Among the patients with classic juvenile pilocytic astrocytomas of the cerebellum 7 had residual tumor, which progressed in 2 patients, both of whom had high AgNOR scores. Among 7 patients with optic/hypothalamic tumors the 3 with rapidly progressing tumors all had very high AgNOR scores. The determination of AgNOR expression might be helpful in selection of patients with residual tumor after surgery, who may benefit from additional chemotherapy or (stereotactic) radiation therapy.

Substance abuse treatment and the recurrence of maltreatment among caregivers with children living at home: a propensity score analysis.

Policy and programmatic initiatives of the last decade have focused on increased coordination of services and expansion of prompt substance abuse treatment for mothers initially involved with child welfare services (CWS). Yet, little evidence has been amassed concerning the implications of this approach on the recurrent need for CWS. Data are from a large national probability sample of children and their caregivers involved with CWS following an allegation of maltreatment. Data include the recurrence of maltreatment reports for this group of children who remain at home. Selected from 1,101 caregivers with an indicated substance abuse problem, a group of 224 clients who did not receive services were compared with 224 treated clients. Event history analyses showed that clients who received substance abuse treatment were nearly twice as likely to have another child abuse report within 18 months. Reasons why participation in substance abuse treatment may result in greater involvement with CWS are posited.

DNA topoisomerase II-alpha and cyclin A immunoexpression in meningiomas and its prognostic significance: an analysis of 263 cases.

CONTEXT: Routine pathologic examination cannot distinctively predict the clinical course of meningiomas because even histologically benign tumors may recur after gross total resection. Therefore, numerous efforts have been made to evaluate the meningioma growth fraction and its prognostic value. However, a universally applicable proliferative marker for meningioma outcome is not yet a reality. OBJECTIVE: To investigate the prognostic utility of 3 proliferative markers, namely, Ki-67, DNA topoisomerase II-alpha (topoII), and cyclin A in a representative series of intracranial meningiomas. DESIGN: Two hundred sixty-three adult patients with intracranial meningiomas (208 benign, 42 atypical, and 13 anaplastic) were studied retrospectively. Tumor specimens were immunohistochemically examined with antibodies to Ki-67 (MM-1), topoII, and cyclin A. A computerized color image analyzer was used to count immunostained nuclei. RESULTS: The topoII and cyclin A scores exhibited a close correlation with Ki-67 immunostaining. Significant differences between the indices for all 3 markers were noted among the 3 grades of meningiomas. The scores for all 3 markers were significantly different between recurrent and nonrecurrent meningiomas, including benign tumors that were treated with gross total resection. Recurrence-free survival was significantly reduced for cases with a Ki-67 labeling index (LI) of 4.4% or greater, a topoII LI of 3.2% or greater, and a cyclin A LI of 3.1% or greater. Multivariate analysis revealed that the risk of recurrence for the entire meningioma cohort was significantly associated with tumor grade (hazard ratio = 2.7; P =.004), topoII LI of 3.2% or greater (hazard ratio = 5.5; P <.001), and a cyclin A LI of 3.1% or greater (hazard ratio = 2.4; P =.01). CONCLUSIONS: There is a close correlation in the expression of these 3 proliferative markers in meningiomas, and all of the markers showed a significant association with tumor grade, recurrence rate, and recurrence-free survival. Consequently, in addition to Ki-67, immunoexpression of topoII and cyclin A is available for predicting meningioma recurrence. Moreover, the topoII and cyclin A staining scores were found to be more sensitive predictors for meningioma progression than Ki-67 and, therefore, either of these 2 markers may prove to be clinically informative and useful.
