Effect of viral status on recurrence after liver resection for patients with hepatitis B virus-related hepatocellular carcinoma.

BACKGROUND: Risk factors for recurrence after resection of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) require more precise definition. METHODS: Forty patients who underwent liver resection for HBV-related HCC were studied. Their clinical findings, laboratory data (including viral status), pathologic findings, and operative methods were evaluated for recurrence risk in univariate and multivariate analyses. RESULTS: The HB envelope (HBe) antigen, wild-type HBV, intrahepatic metastases, elevated serum activities of aspartate aminotransferase and alanine aminotransferase, and moderately or severely active hepatitis were more likely to be found in patients with a high viral load than in patients with a low viral load. Precore mutant-type HBV was more likely to be found in patients with a low viral load than in patients with a high viral load. The platelet count was significantly lower in the patients with a high viral load. A high viral load, the presence of wild-type HBV, the absence of anti-HBe, the absence of precore mutant-type HBV, Child score B, a low platelet count, and a positive surgical margin were risk factors for recurrence in univariate analysis. A nonanatomic resection tended to be a risk factor. A high viral load and positive surgical margin were independent risk factors for recurrence. CONCLUSIONS: The measurement of viral load and detection of anti-HBe, wild-type HBV, and precore mutant-type HBV are useful for estimating a patient's prognosis after resection of HBV-related HCC.

Evaluation of the prognostic significance of androgen receptor expression in metastatic breast cancer.

The purpose of this study was to investigate the influence of androgen receptor (AR) expression in tumour tissue on survival of patients with metastatic breast cancer. Tumour specimens from 232 patients with metastatic breast cancer were examined for presence of AR by immunohistochemistry. According to the extent of immunostaining, AR expression was classified as score 0, 1+, 2+, or 3+. AR positivity was observed in 164 (70.7%) tumours. The median survival after disease recurrence (SAR) of patients with AR-expressing tumours was significantly longer compared to that of patients with AR-negative tumours (21.89 months, 95% CI 17.23-26.55 vs 11.99 months, 95% CI 9.36-14.62; log-rank test 0.0282). In addition, patients with AR score 3+ had a significantly longer disease-free survival (DFS) compared to patients with AR score 0, 1+, and 2+, (24.67 months, 95% CI 13.72-35.62 vs 16.36 months, 95% CI 13.18-19.54, log-rank test 0.0043). Multivariate Cox analyses showed no statistically significant influence of AR expression on DFS or SAR. In conclusion, SAR is significantly longer in patients with AR-expressing breast carcinoma. However, AR expression is not an independent prognostic factor for SAR in metastatic breast cancer.

Noncontact sidefire laser ablation of the prostate.

Continuing experience with Nd:YAG noncontact sidefiring laser fibers over the past 4 years has shown encouraging results. Thus far, of the 198 patients treated with the 60 W/60 seconds technique since October 1990, a total of 74 were available for long-term evaluation (69 at 12 months and 29 at 24 months). The AUA Symptom Scores, Qmax (peak uroflow rates), and postvoiding residual urine volumes demonstrated marked improvement. The complications included 16 instances of recurrent obstructive symptoms necessitating revision. Three patients suffered urinary tract infections, two patients developed bladder neck stenosis, four anticoagulated patients with clot retention required blood transfusions, and three patients had epididymoorchitis. Follow-up at 12 and 24 months showed sustained reduction in AUA Symptom Scores and maintained improvement of the peak flow rates and residual volumes. These results demonstrate the safety and clinical applicability of laser ablation of the prostate and its potential usefulness as a less invasive therapy for benign hyperplasia.

Randomized controlled trial comparing prolene hernia system and lichtenstein method for inguinal hernia repair.

BACKGROUND: There are no data regarding the long-term outcomes of prolene hernia system (PHS) mesh in the published reports. The aim of the study was to compare the short-term and long-term outcomes of the PHS mesh with the Lichtenstein mesh technique. METHODS: Sixty-four patients with inguinal hernia were randomized to undergo either a PHS or a Lichtenstein repair under local anaesthesia as a day case. Early outcome measures were duration of surgery, pain scores, analgesic requirements, time to return to work, driving and full activity. Long-term outcome measures were chronic groin pain and recurrence. RESULTS: Mean duration of surgery in the PHS group was 36 min (SD +/- 11) versus 34 min in the Lichtenstein group (SD +/- 8; P = 0.3). There was no significant difference in analgesic requirements (P = 0.65). Overall mean pain score was 3.5/10 versus 2.5/10 (P = 0.1). Mean time to return to work was 42 versus 30 days (P = 0.3), returning to driving was 20 versus 14 days (P = 0.2) and full activity was 21 versus 22 days (P = 0.8). Chronic groin pain developed in four patients in the PHS group (12.9%) and in five patients in the Lichtenstein group (15.1%; P > 0.05). One patient developed recurrent herniation in the PHS group. The median follow up was 4.2 years (range, 4-4.6 years). Patient satisfaction was very high with both the techniques. CONCLUSION: There is no significant difference in the early and long-term outcomes between PHS and Lichtenstein hernia repairs. The PHS technique involving preperitoneal dissection is well tolerated and easy to carry out under local anaesthesia.

Histopathological prognostic factors in patients with cervical cancer treated with radical hysterectomy and postoperative radiotherapy.

BACKGROUND: Many studies have been performed, on the clinical outcome and prognostic factors in patients with cervical cancer treated with radical hysterectomy and postoperative radiotherapy, but no useful method for predicting the risk of recurrence has been established. The purpose of this study was to analyze histopathological prognostic factors. In addition, we proposed a new risk classification and evaluated its usefulness. METHODS: One hundred and thirty patients with stage I-II uterine cervical cancer were treated with radical hysterectomy and postoperative radiotherapy at Ehime University Hospital between 1978 and 1997. All surgical specimens were reviewed, and the relationship between histopathological factors and the clinical outcome was analyzed. RESULTS: Of the histopathological prognostic factors of the surgical specimens analyzed, six factors (parametrial invasion, venous infiltration, pelvic lymph node metastases, thickness of the residual muscular layer, tumor depth, and tumor growth pattern) were significant prognostic factors. In particular, venous infiltration and pelvic lymph node metastases were strongly correlated with recurrence. Using the above five factors (excluding the thickness of the residual muscle layer), all patients were scored based on the total number of poor prognostic factors, and were classified into three groups. Patients with a score of 0-1 were classified as the low-risk group, those with a score of 2 as the intermediate group, and those with a score of 3-5 as the high-risk group. The 5-year disease-free survival rates were 93% in the low-risk group, 82% in the intermediate group, and 56% in the high-risk group (P < 0.05). CONCLUSION: Six prognostic factors were found. Our risk classification seems to be clinically useful to predict which patients are at risk of recurrence.

Perioperative outcomes and complications of laparoscopic ventral hernia repair.

BACKGROUND: Laparoscopic techniques are being used increasingly in the repair of ventral hernias and offer the potential benefits of a shorter hospital stay, decreased wound complications, and possibly a lower recurrence rate. Despite good results from high-volume centers, significant complications may occur with this approach and the morbidity of incisional hernia repair may be underestimated. The purpose of this study was to review our experience with laparoscopic ventral hernia repair (LVHR) since its inception at our institution. METHODS: Medical records of all patients who underwent LVHR at a single institution from May 2000 through December 2003 were reviewed. Preoperative and postoperative variables including complications were analyzed. Follow-up evaluation was by office visit and phone survey with assessment of patient satisfaction scores. Data are expressed as mean +/- SD. RESULTS: A total of 121 LVHR were performed in 116 patients (52 men, 64 women; mean age, 57 +/- 13 y; mean body mass index, 35 +/- 8). Hernias were recurrent in 35 cases (28.9%), with a mean of 1.4 prior repairs (range, 1-7). The mean defect size was 109 +/- 126 cm2 and the average mesh size used was 256 +/- 192 cm2. Operating time was 147 +/- 45 minutes, and the hospital stay averaged 1.7 +/- 1 days. Twelve cases (9.9%) were converted to open operation, most commonly because of extensive adhesions. Extensive laparoscopic adhesiolysis was necessary in 29 cases (26.6%). Overall, perioperative complications occurred in 33 cases (27.3%), 13 of which (39.3%) were persistent seromas. Major complications were seen in 9 cases (7.4%). There were 4 enterotomies (3.3%): 3 occurred as a result of adhesiolysis and 1 resulted from a trocar injury; 2 were detected intraoperatively and were converted to open operation and 2 presented postoperatively. One of these patients developed sepsis and died. Follow-up evaluation was available for 83.6% of cases at a mean interval of 22 +/- 16 months after repair. The hernia recurrence rate was 9.3% (9 cases) and was detected at a median of 6 months postoperatively. The overall patient satisfaction score was high at 4.3 +/- 1.1 (scale, 1-5). CONCLUSIONS: Laparoscopic repair is effective for the vast majority of patients with primary or recurrent ventral hernias and results in hernia recurrence rates of less than 10%, with high patient satisfaction scores. Although seroma is the most common complication, major morbidity occurred in 7.4% of the patients in our series. Enterotomy is the most common serious complication and may result in sepsis and death.

Early results of a randomised trial comparing Prolene and VyproII-mesh in endoscopic extraperitoneal inguinal hernia repair (TEP) of recurrent unilateral hernias.

The purpose of this study was to compare a lightweight mesh to a standard polypropylene hernia mesh in endoscopic extraperitoneal hernioplasty in recurrent hernias. A total of 140 men with recurrent unilateral inguinal hernias were randomised to a totally extraperitoneal endoscopic hernioplasty (TEP) with Prolene or VyproII in a single-blinded multi-center trial. The randomisation and all data handling were performed through the Internet. 137 patients were operated as allocated. Follow-up was completed in 88% of the patients. The median operation times were 55 (24-125) min and 53.5 (21-123) min for the Prolene and VyproII groups, respectively. The meshes had comparable results in the surgeon's assessment of the handling of the mesh, return to work, return to daily activities, complications, postoperative pain and quality of life during the first 8 weeks of rehabilitation, except in General Health (GH) SF-36, where the VyproII-group had a significantly better score (P=0.045). The use of Prolene and VyproII-meshes in endoscopic repair of recurrent inguinal hernia seems to result in similar short-term outcomes and quality of life.

Positive surgical margins with radical retropubic prostatectomy: anatomic site-specific pathologic analysis and impact on prognosis.

OBJECTIVES: To correlate the extent and location of positive surgical margins after radical prostatectomy with disease progression. METHODS: Data on 495 patients who underwent radical prostatectomy by one surgeon were analyzed. All radical prostatectomy specimens were sectioned entirely using 2 to 3-mm step sections by one pathologist. One hundred fifty-one patients (30.5%) had one or more positive surgical margins and were subjected to further detailed analysis. Recurrence was defined as a serum prostate-specific antigen (PSA) level of 0.2 ng/mL and rising on at least two postoperative measurements. RESULTS: The mean follow-up was 25.3 months (range 3 to 73). The overall recurrence rate was 13.3%. Neoadjuvant hormonal treatment was given to 37 (25%) of those with a positive margin. Patients with positive surgical margins had a significantly higher incidence of recurrence compared with those with negative margins (27.8% versus 6.9%, P = 0.001). The recurrence rate for various locations was 29% apex/urethra, 30% posterior, 33% anterior, 36% lateral, 48% posterolateral, and 57% bladder neck. Time to recurrence was shorter in patients older than 70 years (P<0.055); with a preoperative PSA greater than 10 ng/mL (P<0.0001); with a biopsy Gleason score greater than 7 (P = 0.02); with a prostatectomy Gleason score greater than 7 (P<0.001); with seminal vesicle invasion (P = 0.0001); having more than 1 location of a positive margin (P = 0.002); or having a positive margin at the bladder neck (P = 0.0003) or the posterolateral surface of the prostate (P = 0.02) compared with other locations. Multivariate proportional hazards analyses indicated that age older than 70 (P = 0.005), a prostatectomy Gleason score of 7 (P = 0.015) or 8 to 10 (P = 0.003), and positive margin(s) at the bladder neck (P = 0.003) were independently associated with a shorter time to recurrence among patients with a positive margin. CONCLUSIONS: In our study, among patients with positive surgical margins, those with multiple positive margins, or a margin involving the bladder neck or the posterolateral surface of the specimen carried a higher risk of progression. A positive margin at the bladder neck appears to be the most significant adverse prognostic indicator. This information may help in decisions regarding additional therapy.

Usefulness of atrial fibrillation burden as a predictor for success of pulmonary vein isolation.

BACKGROUND: The definition of symptomatic improvement after pulmonary vein isolation (PVI) is controversial. We assessed primarily the usefulness and predictive accuracy (PA) of AF (atrial fibrillation) burden (AFB) within the first 3 months after the procedure as an early predictor for curative success as well as reduction of symptoms. METHODS: We studied 100 pts (62 men, mean age: 54 +/- 9 years, LVEF: 57 +/- 9%, paroxysmal AF, 85, persistent AF, 15) who underwent PVI. RF ablation was used in 63 patients. The combination of cryoablation and RF (Hybrid therapy) was used in the remaining 37 patients, in 19 patients of whom additionally linear lesions were performed. All patients were followed up 3 months after PVI (the blanking period) and every 3 months thereafter. The significance of early recurrence of AF (ERAF) was separately analyzed for RF and for hybrid therapy arm. Quality of life (QoL) was assessed using the physical composite summary score (PCS) and mental composite summary score (MCS). AFB was dichotomized at: 0, 0.5, 1, 6, 12, and 24 hours. RESULTS: ANOVA revealed significant differences between PCS at baseline and after PVI in patients without recurrence and with those with postablation AFB <12 hours. There was no difference between PCS in patients with AFB > or =12 hours within a 3 months interval and PCS at baseline. ERAF occurred in 35% of patients (16 patients, AFB > or =12 hours). Symptomatic ERAF occurred in 29 patients (17 patients AFB > or =12 hours). After the blanking period, documented AF recurrence was found in 50 patients (17 patients, AFB > or =12 hour). Symptomatic late recurrence was found in 47 patients (31 patients with AFB > or =12 hours). Absence of ERAF was revealed to be predictive for long-term success and symptomatic ERAF was found to be predictive for symptomatic AF recurrence (P <0.0001). CONCLUSION: AF recurrence with AFB > or =12 hours within 3 months is associated with a missed improvement of QoL. Symptomatic ERAF predicts recurrence independently of therapy.

Multicenter randomized-controlled clinical trial of probiotics (Lactobacillus johnsonii, LA1) on early endoscopic recurrence of Crohn's disease after lleo-caecal resection.

BACKGROUND: Seventy percent of Crohn's disease (CD) patients exhibit anastomotic recurrence within 1 year after ileo-caecal surgery. Recent clinical trials suggest the beneficial use of probiotics in the control of intestinal inflammation in pouchitis and ulcerative colitis. This study is a multicenter clinical trial evaluating the efficacy of an oral administration of the probiotic LAl on early post-operative endoscopic recurrence of CD. METHODS: Seventy patients with CD were enrolled prior to elective ileo-caecal resection and randomly assigned after surgery to daily treatment with either Lactobacillus johnsonii, LA1, Nestle (1010 colony-forming units, CFU) (group A, n = 34) or placebo (group B, n = 36) for 12 weeks. The primary objective was to assess the effect of LAl on the endoscopic recurrence rate at 12 weeks. Stratification was performed according to smoking status at randomization. RESULTS: Seven and 14 patients were excluded in the LA1 and placebo groups, respectively. In intention-to-treat analysis, the mean endoscopic score was not significantly different between the two treatment groups at 3 months (LA1 versus placebo: 1.50 +/- 1.32 versus 1.22+/-1.37, treatment effect: P = 0.48, smoke effect: P = 0.72). The percentage of patients with severe recurrence (i3 + i4) was 21% and 15% in the LAl and placebo groups, respectively (P = 0.33). Using a per-protocol (PP) analysis, the mean endoscopic score was not significantly different between the two treatment groups (LAl versus placebo groups: 1.44 +/-1.31 versus 1.05 +/- 1.21, P = 0.32). The percentage of patients with severe recurrence (i3 + i4) was 19% and 9% in the LAl and placebo groups, respectively (P = 0.054). Clinical relapse rate (CDAI [CD activity index] > 150, with an increase of CDAI > 70 points or greater from baseline) in the LAl and placebo groups was 15% (4/27) and 13.5% (3/22), respectively (PP analysis: chi-square test, P = 0.91 and log-rank test: P = 0.79). CONCLUSION: Oral administration of the probiotic LA1 in patients with CD failed to prevent early endoscopic recurrence at 12 weeks after ileo-caecal resection.

Does the time from biopsy to surgery affect biochemical recurrence after radical prostatectomy?

OBJECTIVE: To evaluate whether the time from biopsy to radical prostatectomy (RP) predicts the biochemical recurrence (BCR) after RP, as men diagnosed with clinically localized prostate cancer have several available treatment options and investigating these alternatives may delay the initiation of definitive therapy. PATIENTS AND METHODS: We identified 3969 consecutive patients who had RP for clinically localized prostate cancer from 1987 to 2002; those eligible for the study had RP within a year of diagnosis. The interval between biopsy and RP was analysed both as a continuous and as a dichotomous variable (divided at 3 months). Multivariate analysis was used to evaluate the impact of time to RP on BCR. Subsets were also analysed for the effect of time to RP in patients considered to be at high risk of recurrence, with group 1 having a prostate specific antigen (PSA) level of > or = 20 ng/mL, a biopsy Gleason score of > or = 8, or clinical stage > or = T2c; and group 2 assessed as having a >40% probability of BCR using a preoperative nomogram. RESULTS: In all, 3149 patients met the inclusion criteria and had a mean (interquartile range) follow-up after RP of 5.4 (2.2-7.9) years. Multivariate analysis showed that the year of biopsy, PSA level before biopsy, clinical stage and biopsy Gleason score (all P < 0.001) were significantly associated with BCR after RP. The time to RP, treated either as a continuous variable (P = 0.252) or when categorized at 3 months (P = 0.939), failed to predict BCR. Further, the time to RP was not an independent predictor of BCR for patients at high risk of recurrence in group 1 (P = 0.147) or group 2 (P = 0.548). CONCLUSIONS: The time from biopsy to RP did not influence the probability of BCR for men who had RP within a year of diagnosis, even for those considered to be at high risk of BCR. Instead, the clinical and pathological features of the cancer provided the best estimate of the risk of BCR.

Expression of neu/c-erbB-2 in human brain tumors.

The neu/c-erbB-2 oncogene encodes a 185 kd transmembrane protein (p185). Here we have used the monoclonal antibody (mAb) 3B5 to determine the expression of p185 in a series of fixed biopsy specimens of 180 human brain tumors, including the most frequent entities and, in addition, 18 recurrent gliomas with malignant progression. In summary, 3B5 immunoreaction was most prominent in astrocytomas of different grades of malignancies and in meningiomas. In World Health Organization (WHO) grade II astrocytomas mab 3B5-immunoreaction was related to the cytomorphological phenotype. Fibrillary astrocytomas showed no or only a weak immunoreaction (four of five, 80%) in contrast with protoplasmic or gemistocytic astrocytomas, where a strong reaction was observed in most cases (six of nine, 66.6%, and four of five, 80%, respectively). In WHO grade II to WHO grade IV astrocytomas a trend towards higher scores with increasing grade was found. In a limited number of cases (18 gliomas and two meningiomas) of the tumor series tested other mAbs against neu/c-erbB-2 epitopes, especially the mabs 9G6 and CB11, gave qualitatively comparable results. In WHO grade I pilocytic astrocytomas a wide range of 3B5 immunoreactivity has been observed. The results of in situ hybridization using a 32P-labeled neu/erbB-2 RNA probe performed on four WHO grade I and II astrocytomas, seven WHO grade IV glioblastomas, one WHO grade II oligoastrocytoma, one WHO grade III anaplastic astrocytoma, and three WHO grade I meningiomas were consistent with these immunomorphological data, and Northern blot analysis also indicated an overexpression of neu/c-erbB-2 mRNA in gliomas of different grades of malignancy and in meningiomas. These elevated neu-erbB-2 transcript levels occurred in the absence of gene amplification. In a second series of recurrent gliomas with malignant progression (n = 18) the higher 3B5-immunoreaction scores were apparent in the more malignant recurrent gliomas. In this series the overexpression of neu/c-erbB-2 parallels glioma progression. In our cases it was not, however, correlated with the postoperative relapse-free interval or with the overall length of survival.

Arthroscopic Bankart repair with knotless suture anchor for traumatic anterior shoulder instability: results of short-term follow-up.

PURPOSE: To assess the clinical results of arthroscopic Bankart repair with the knotless suture anchor for traumatic recurrent anterior shoulder instability. METHODS: A total of 47 patients with traumatic recurrent anterior shoulder instability and without severe glenoid bone defect who underwent arthroscopic Bankart repair with knotless suture anchors and were followed-up for longer than 2 years were included in the present study. The average age at surgery was 26 years (range, 16 to 49 years), with an average follow-up period of 28 months (range, 24 to 38 months). RESULTS: Clinical score as evaluated by the modified Rowe score advanced from 31 points to 91 points. In all, 35 patients were scored as excellent and 6 as good; the success rate was 87% (41 of 47), and the recurrence rate was 6.4% (3 of 47). External rotation was reduced by 8 degrees at adduction and by 6 degrees at 90 degrees of abduction. Of 12 patients, 7 (58%) returned completely to collision sports at preinjury levels, and 2 of 12 (17%) returned at a lower level. We experienced anchor-related trouble in 3 cases. One was the backwardness of the anchor at 2 months after operation. Breakage of the anchor loop occurred during the procedures in 2 cases. CONCLUSIONS: The clinical results of arthroscopic Bankart repair with knotless suture anchor were favorable; however, some pitfalls, such as the backwardness of the anchor and cutting of the anchor loop, were experienced. When using this anchor, its properties should be well recognized. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Growth, morbidity, and mortality in a cohort of institutionalized HIV-1-infected African children.

OBJECTIVE: As a result of the HIV epidemic in Africa, much debate exists on whether institutionalized compared with community-based care provides optimum management of infected children. Previous reports calculated 89% mortality by age 3 years among outpatients in Malawi. No similar data are available for infected children in institutionalized care. We characterized patterns of morbidity and mortality among HIV-1-infected children residing at an orphanage in Nairobi. METHODS: Medical records for 174 children followed over 5 years were reviewed. Mortality was analyzed by Kaplan-Meier methods with adjustment to account for survival in the community before admission. Anthropometric indices were calculated to include mean z scores for weight for length and length for age. Low indices reflected wasting and stunting. Opportunistic infections were documented. RESULTS: Of 174 children, 64 had died. Survival was 70% at age 3 years. Morbidity included recurrent respiratory tract infections, gastroenteritis, parotitis, and lymphoid interstitial pneumonitis. No new cases of tuberculosis disease were noted after admission. Mean z scores for length for age suggested overall stunting (z = -1.65). Wasting was not observed (z = -0.39). CONCLUSION: The optimal form of care for HIV-infected children in resource-poor settings may be the development of similar homes. Absence of tuberculosis disease in long-standing residents may have contributed to improved survival. Stunting in the absence of wasting implied that growth was compromised by opportunistic infections and other cofactors.

Subfascial endoscopic perforator vein surgery in patients with post-thrombotic venous insufficiency--is it justified?

Previous results following subfascial endoscopic perforator vein surgery were reported to be worse in post-thrombotic syndrome than in limbs with primary valvular incompetence. This report comprises a larger patient cohort with longer follow-up. The goal of this study was to determine if subfascial endoscopic perforator vein surgery is justified in patients with post-thrombotic venous insufficiency. The clinical data of 91 consecutive patients who underwent subfascial endoscopic perforator vein surgery with or without superficial reflux ablation over a 7-year period from May 1993 to June 2000 were retrospectively analyzed. Fifty-four females and 37 males (median age, 53 years; range, 20-77) underwent 103 subfascial endoscopic perforator vein surgery procedures. Forty-two limbs were classified as C6 (active ulcer), 34 as C5 (healed ulcer), and 24 as C4 (lipodermatosclerosis). Thirty procedures were performed in post-thrombotic limbs. Concomitant superficial reflux ablation was performed in 74 limbs (72%); saphenous vein stripping had been previously performed in 29 (28%). Deep venous incompetence was present in 89% of limbs; 13% had venous outflow obstruction on plethysmography. Cumulative ulcer healing in post-thrombotic limbs was not significantly different from limbs with primary valvular incompetence; 30-, 60-, and 90-day healing rates were 44%, 72%, and 72% vs 39%, 70%, and 87%, respectively (p = 0.35). On univariate analysis, the presence of ulcer greater than 2 cm in diameter was associated with delayed ulcer healing (p = 0.02). Cumulative ulcer recurrence in all limbs was 4%, 20%, and 27% at 1, 3, and 5 years, respectively. Ulcer recurrence in post-thrombotic limbs was higher than in limbs with primary valvular incompetence at 1, 3, and 5 years; 16%, 47%, and 56% vs 0%, 8%, and 15%, respectively (p = 0.001). Recurrent ulcers were small, superficial, and easier to heal. Clinical improvement was significant even in post-thrombotic limbs; median clinical score decreased from 9.5 to 3 (p = 0.001), and median outcome score was +2 (mean 1.9; range, -1 to 3). Median clinical score in patients with primary valvular incompetence improved from 6 to 1.5 (p = 0.0001). Subfascial endoscopic perforator vein surgery with superficial reflux ablation promoted ulcer healing, improved clinical outcome, and resulted in a low long-term ulcer recurrence rate in limbs with primary valvular incompetence. Despite good clinical outcome in post-thrombotic limbs, ulcer recurrence was high. These results imply that the role of subfascial endoscopic perforator vein surgery with superficial reflux ablation in patients with post-thrombotic limbs continues to be controversial.

Use of OKT3 is associated with early and severe recurrence of hepatitis C after liver transplantation.

OBJECTIVE: To determine whether increased immunosuppression is a contributor to poor outcome in hepatitis C-infected orthotopic liver transplant (OLT) recipients, we retrospectively analyzed the consequences of using OKT3 in our program for steroid-resistant rejection (SRR). METHODS: We compared the histological recurrence of HCV in two contemporary cohorts of OLT recipients. Group 1 consisted of HCV-positive patients who received OKT3 for SRR (n = 19). Group 2 (n = 33) consisted of age-, gender-, and initial immunosuppression-matched HCV-positive controls who were treated with at least one steroid pulse for acute cellular rejection but who did not require treatment with OKT3. Liver biopsies were obtained per protocol within the first month and as necessary to evaluate abnormalities in serum liver chemistries. RESULTS: Mean and median follow-up were comparable for the two groups. Recurrence of HCV was diagnosed by histological verification and was documented in 16 of 19 (84.2%) group 1 patients versus 17 of 33 (51.5%) group 2 patients (p = 0.03). The interval to recurrence was significantly shorter in patients who received OKT3 (p = 0.028). Logistic regression identified OKT3 as a significant risk factor for the recurrence of HCV within the first year post-OLT (p = 0.0004). The histological severity score, based on the most recent liver biopsy at long-term follow-up or the explant biopsy if the patient required retransplantation, was significantly higher in group 1. Moreover, cirrhosis was demonstrable in a greater proportion of allografts in patients who had received OKT3 at some point (26.3% vs. 6%, p = 0.028). Long-term follow-up revealed a trend toward higher alanine aminotransferase levels (p = 0.05) and total bilirubin (p = 0.08) in group 1 patients. CONCLUSIONS: Our data suggest that allograft hepatitis in patients with preexisting HCV occurs earlier and with greater severity in patients treated with OKT3 for SRR, compared with age-, gender-, and initial immunosuppression-matched contemporary controls. Treatment of SRR with OKT3 may jeopardize long-term allograft function and survival in HCV-infected recipients by enhancing viral hepatitis recurrence. Clearly, the recognition of recurrent HCV and differentiation from acute cellular rejection remains a crucial issue in managing the OLT recipient with HCV.

Hip joint remodeling in an adult following excision of a giant cell tumor involving the acetabulum: a case report and literature review.

We describe a 47-year-old man with a giant cell tumor of bone involving the acetabulum treated with curettage and bone grafting which resulted in good remodeling of the hip joint. The patient had a 15 x 18-cm(2) mass lesion extending from the right ischium to the acetabulum. Treatment included curettage, phenol, and ethanol application as an adjuvant, and cancellous bone allografting was performed on the subchondral area of the acetabulum. The posterior column of the acetabulum was disappeared by tumor invasion. Despite central migration of the femoral head, adequate hip joint repair was achieved without surgery 5.5 years postoperatively and with no tumor recurrence. The patient could walk without pain or ambulation aids; hip range of motion was 100 degrees for flexion, 0 degrees for extension, 30 degrees for abduction, 45 degrees for external rotation, and 10 degrees for internal rotation, and the functional result was 93.3% in the Enneking scoring system. We performed intralesional curettage with phenol and ethanol adjuvant therapy for pelvic giant cell tumor without tumor recurrence, and good repair of a hip joint adaptation can be achieved even in an adult patient.

Prognostic significance of tumor volume after radical prostatectomy: a multivariate analysis of pathological prognostic factors.

OBJECTIVES: To analyze the association between Gleason score, stage and status of surgical margins with tumor volume in prostate cancer progression after radical prostatectomy. METHODS: 200 consecutive radical prostatectomy specimens were analyzed. Preoperative clinical stage, PSA, results of prostate biopsies as well as pathological results were noted. A biochemical recurrence was defined as a single, postoperative detectable PSA level (>0.2 ng/ml). Tumor volume was compared to postoperative staging, Gleason score, and surgical margin status to predict tumor progression. Univariate and multivariate analysis using stepwise logistic regression were used to identify parameters with additional prognostic value. RESULTS: Pathological results of the prostatectomy specimens showed 149 (74.5%) pT2a-b, 29 (14.5%) pT3a and 22 (11%) pT3b tumors. Tumor volume was 0.57 cc for pT2a, 1.2cc for pT2b, 1.7cc for pT3a and 2.9cc for pT3b, respectively (p<0.05). Taken together, mean volume for pT2 and pT3 were 1.06 and 2.2 cc, respectively (p<0.0001). Five-year progression-free actuarial survival was 69.7%. Using univariate analysis, tumor progression correlated with final Gleason score (p<0.0007), positive surgical margins (p=0.02), tumor volume (p=0.009) and stage (p<0.0001). In a multivariate analysis, tumor progression correlated only with the final Gleason score (p=0.04) and stage (p=0.0002). CONCLUSION: Gleason score and pathological stage are independent factors to predict prostate cancer progression after radical prostatectomy. When these parameters are known, tumor volume does not provide additional information.
