Prognostic index score and clinical prediction model of local regional recurrence after mastectomy in breast cancer patients.

PURPOSE: To develop clinical prediction models for local regional recurrence (LRR) of breast carcinoma after mastectomy that will be superior to the conventional measures of tumor size and nodal status. METHODS AND MATERIALS: Clinical information from 1,010 invasive breast cancer patients who had primary modified radical mastectomy formed the database of the training and testing of clinical prognostic and prediction models of LRR. Cox proportional hazards analysis and Bayesian tree analysis were the core methodologies from which these models were built. To generate a prognostic index model, 15 clinical variables were examined for their impact on LRR. Patients were stratified by lymph node involvement (<4 vs. >or =4) and local regional status (recurrent vs. control) and then, within strata, randomly split into training and test data sets of equal size. To establish prediction tree models, 255 patients were selected by the criteria of having had LRR (53 patients) or no evidence of LRR without postmastectomy radiotherapy (PMRT) (202 patients). RESULTS: With these models, patients can be divided into low-, intermediate-, and high-risk groups on the basis of axillary nodal status, estrogen receptor status, lymphovascular invasion, and age at diagnosis. In the low-risk group, there is no influence of PMRT on either LRR or survival. For intermediate-risk patients, PMRT improves LR control but not metastases-free or overall survival. For the high-risk patients, however, PMRT improves both LR control and metastasis-free and overall survival. CONCLUSION: The prognostic score and predictive index are useful methods to estimate the risk of LRR in breast cancer patients after mastectomy and for estimating the potential benefits of PMRT. These models provide additional information criteria for selection of patients for PMRT, compared with the traditional selection criteria of nodal status and tumor size.

Multifactorial analysis of survival and recurrences in differentiated thyroid cancer. Comparative evaluation of usefulness of AGES, MACIS, and risk group scores in Mexican population.

Many risk factors have been identified in differentiated thyroid cancer, with them, some prognostic scores have been designed to asign the risk of recurrence and survival. In Mexican population, this type of study is scarce. This is a retrospective review of 180 patients with differentiated thyroid cancer completely treated at the Hospital de Oncologia, IMSS, in Mexico City from 1980 to 1990. All prognostic factors were analyzed and a score obtained either by the method of AGES, MACIS, or SKMH. Correlation of recurrences and survival was carried out according to score or risk assignment. There was a predominance of females (4.8:1), 48% had metastatic cervical nodes, median tumor size was 4 cm, 16% had multiple macroscopic thyroid tumors, in 12% resection was incomplete, 96% were papillary, and 4% follicular cancers. According to AGES, 46% were high risk patients, 49.4% with MACIS and 45.5% with SKMH, respectively. Median follow-up was 8.3 years. There were 67 (37%) recurrences. Ten-year overall survival was 89.4% and disease-free survival was 79.2%. There was no statistical significant difference of survival of AGES until the score reached 6 or more or the MACIS score reached 8 or more. Cox multivariate model showed that above the age of 45, tumor size of 5 cm or more, follicular histology, multiple macroscopic thyroid tumors, and extracapsular node invasion affected ten-year survival. In conclusions our patients are diagnosed at more advanced stages than patients in the U.S. or European countries. Nearly one half of our patients belonged to the high-risk group. This study confirms that patients over the age of 45, tumor size > 5 cm, and follicular histology are adverse prognostic factors and report that extracapsular node invasion and multiple macroscopic thyroid tumors are also adverse prognostic factors. In Mexican population, with 50% of high-risk patients, AGES and MACIS scores reached statistical differences with higher qualifications than observed in the U.S.

Long-term results of wide-field brachytherapy as the sole method of radiation therapy after segmental mastectomy for T(is,1,2) breast cancer.

BACKGROUND: We hypothesized that wide-field brachytherapy (BRT) after margin negative excision would result in complication rates, local recurrence rates, and cosmesis scores equivalent to external beam radiotherapy (ERT). METHODS: Patients with T(is,1,2) tumors less than or equal to 4 cm, 0 to 3 positive axillary nodes, and negative inked surgical margins were entered prospectively into BRT phase I/II trial. Patients who met the eligibility criteria for BRT but were treated with ERT during the same time period were retrospectively identified as controls. A blinded panel of healthcare professionals graded cosmetic outcome. RESULTS: Fifty patients with 51 breast cancers received BRT from January 1992 to October 1993. We identified 94 patients eligible for BRT but concurrently treated with ERT. At a median follow-up of 75 months, the two groups were similar for grade III treatment toxicities, local/regional recurrence rates, and cosmesis scores. CONCLUSIONS: For selected breast cancer patients undergoing breast-conserving therapy, BRT is an attractive alternative to ERT.

[Electron beam irradiation is effective in the treatment of skin carcinomas; a comparison with superficial roentgen therapy].

OBJECTIVE: To compare recurrence rates and cosmetic results after electron beam therapy versus superficial X-ray therapy for basal cell and squamous cell carcinomas of the skin. SETTING: Department of Radiotherapy, University Hospital Leiden, the Netherlands. DESIGN: Retrospective. METHODS: A retrospective analysis was performed of 389 histologically confirmed basal cell and squamous cell carcinomas of the skin (1980-1990), treated with either superficial X-rays or electron beam therapy, with regard to local recurrence rates and cosmetics scored with an arbitrary three point scale. RESULTS: Of 389 patients 19 developed a local recurrence (4.9%). For small tumours (irradiated surfaces < or = 10 cm2) a local recurrence rate of 2.2% was observed, both after electron beam therapy and after superficial X-ray therapy. Large tumours (irradiated surface > 50 cm2, treated with electron beam) had a higher recurrence rate (13.8%) as had tumours which had been treated before. The cosmetic results with electron beam treatment were better, because smaller fractions were used compared with superficial X-ray treatment. CONCLUSION: In our hands electron beam treatment was not inferior to superficial X-ray treatment, cosmetically even better and also applicable in case of larger tumours. The inferior results of electron beam therapy reported in literature may be due to technical factors.

Successful outpatient management of acute upper gastrointestinal hemorrhage: use of practice guidelines in a large patient series.

BACKGROUND: Acute upper gastrointestinal hemorrhage is a common reason for hospitalization. Clinical and endoscopic characteristics predict outcome. The aim of this study was to determine the characteristics and outcome of patients with acute upper gastrointestinal hemorrhage cared for without hospitalization. METHODS: One hundred seventy-six consecutive patients in a staff-model health maintenance organization were selected for outpatient care based on absolute endoscopic and non-absolute clinical criteria. Clinical and endoscopic characteristics, British national audit "risk scores," and rates of recurrent bleeding, hospitalization, and mortality were determined. RESULTS: Mean patient age (+/- SD) was 56.4 +/- 16.0 years, and 106 patients (60%) were men. One hundred one (57%) had endoscopy within 2 days of the onset of hemorrhage. The mean initial hemoglobin concentration was 11.7 +/- 2.3 mg/dL. Ninety-seven patients (55%) had a peptic ulcer, and 57 (32%) had a British risk score greater than 2. Hospitalization, recurrent bleeding, and mortality occurred in two (1%), one (1%), and zero (0%) patients, respectively, during 16.0 +/- 10.8 months of follow-up. CONCLUSIONS: Many patients with acute upper gastrointestinal hemorrhage can be safely treated as outpatients using endoscopic and clinical guidelines.

Prognostic importance of the nucleolar organizer region score in ovarian epithelial tumors.

OBJECTIVE: The score of the silver-stained nucleolar organizer region (AgNOR) is frequently found to be high in malignant tumors. We studied AgNOR in ovarian epithelial tumors diagnosed in our hospital between 1993 and 1998. MATERIALS AND METHOD: In our study 67 ovarian epithelial tumors (18 cystadenoma, 16 borderline type, 34 cystadenocarcinoma) were stained using the method previously described by Crocker. One-way ANOVA and logistic regression tests were used to find the statistical relationship between grade, recurrence, mortality rates and AgNOR scores in tumors (p values of <0.05 were considered statistically significant). RESULTS: The mean AgNOR scores of 28 mucinous and 39 serous ovary tumors were calculated. The lowest AgNOR score of 1.33 was found in cystadenomas and the highest AgNOR score of 4.92 was found in serous and mucinous cystadenocarcinomas. In addition the relationship between mortality rate, recurrence and AgNOR score in carcinomas were studied. CONCLUSION: AgNOR scores in carcinomas were found to be higher than adenomas, and the highest AgNOR score was found in grade-III carcinomas. This shows that the AgNOR score can be used as a prognostic index in malignancies.

Quality of life and time trade-off utility measures in patients with coronary artery disease.

BACKGROUND: Contemporary clinical trials commonly measure quality of life and medical costs to establish whether therapies are both effective and cost effective. Cost-effectiveness analysis, however, requires a measure of patient utility or preferences for various health states. Because utilities are not often measured directly, we sought to develop a method of translating standard quality-of-life scales into a patient utility measure. METHODS: Five hundred fifty-three patients enrolled in the Bypass Angioplasty Revascularization Investigation Study of Economics and Quality of Life completed a battery of quality-of-life measures and a time trade-off utility assessment an average of 7.3 years after random assignment. RESULTS: The mean time trade-off score was 8.54 (SD = 2.53) out of a maximum of 10; median score was 9.95. The distribution of scores was skewed, with 12% of patients at the highest possible score of 10. Patients with recurrent angina had significantly lower time trade-off scores than patients without angina (mean 7.03 vs 8.70, P <.05). Time trade-off scores were moderately correlated with each quality-of-life measure (Spearman coefficients 0.38-0.52). Time trade-off scores could be predicted by combinations of 4 (r2 = 0.29), 5 (r2 = 0.31), or 6 (r2 = 0.32) variables. CONCLUSIONS: Time trade-off utility scores can be inferred from commonly used quality-of-life measures. Angina significantly reduces patient utility scores.

Histologic malignancy grading in invasive squamous cell carcinoma of the vulva.

A preliminary report on a histologic malignancy grading of vulvar carcinoma is presented. A retrospective histologic study of 40 vulvar carcinoma cases stage I and II (TNM-system) with a minimum five-year follow-up was carried out and correlated to the course of the disease. Morphologic criteria characterizing the tumor cell population, as well as the tumor-host relationship, were examined and scored. The scores obtained could be divided into three groups that correlated well with the clinical outcome. The low-score group had no metastases or recurrence, whereas 82% of the high-score group had both metastases and fatalities. Depth of invasion was found to have a strong correlation to clinical outcome. A more accurate morphologic malignancy grading of such carcinomas could lead to a more individual and often less radical treatment plan.

Individualized prognosis for melanoma patients.

The clinical course of malignant melanoma is notoriously variable. Current approaches to prognostication allow assignment to risk categories but do not permit accurate assessment of prognosis on an individual patient basis. We analyzed a melanoma histology database that comprises 1,042 sequential melanoma patients evaluated by A.J.C. at UCLA between 1980 and 1990 for 30 separate variables according to a standard protocol. After censoring for absent data, a univariate Cox model analysis was performed that showed 20 individual variables that were significantly linked to clinical outcome. A step-up multivariate analysis was then performed. The combined analysis shows 5 variables: gender, site of primary, age relative to 60 years, Breslow thickness, and presence and width of ulceration to be linked to survival. Probability of survival is calculated using a 2-step approach. The survival-linked variables are multiplied to give an individualized risk score. This is converted into probability of survival by the formula .987 (risk score) for 3-year survival, .975 (risk score) for 5-year survival, and .960 (risk score) for 10-year survival. Thus, a 55-year-old woman with a 1.8-mm nonulcerated melanoma on the leg would have a risk score of (1 x 1 x 1 x 2 x 1) = 2 and a predicted probability of survival at 5 years of .9752 (95%) and at 10 years of .9602 (92%). We used similar techniques to develop individualized risk scores for likelihood of recurrence. The significant variables in this case are anatomic site of the primary melanoma, melanoma subtype, Breslow thickness, and presence and width of ulceration. The formulae for likelihood of recurrence at different periods after initial surgical removal of the primary melanoma are at 3 years, .979(risk score); at 5 years, .971(risk score); and at 10 years, .957(risk score). This relatively simple approach to prognostication uses readily available demographic information and is likely to be more accurate than single-factor analysis.

Multimedia article. Success of episioproctotomy for cloaca and rectovaginal fistula.

PURPOSE: Surgical repair of rectovaginal fistula with an advancement flap has had suboptimal results. The existing literature documenting episioproctotomy as a surgical option in females with rectovaginal fistula or cloaca is limited. This study was designed to examine our experience with episioproctotomy in this group. Additionally we were interested in risk factors, which might predict failure. METHODS: All females who had repair of a rectovaginal fistula or cloaca with episioproctotomy from 1998 to 2004 were studied. Data were collected from chart review and telephone contact. This included demographics, body mass index, tobacco use, Crohn's disease, previous surgery, and diverting stoma. RESULTS: Data were obtained from 42 females (mean age, 39.2 (range, 25-70) years). The mean follow-up was 37 (range, 2-84) months. Nine females had a cloaca and the rest had a rectovaginal fistula with an anterior sphincter defect. Eleven (all with anterior tissue) had recurrence of fistula. None with cloaca had recurrence. Eight of 11 recurrences occurred in females who had failed at least one previous repair. No variables that were studied significantly affected recurrence. Median (25th, 75th percentiles) postoperative Wexner incontinence scores for those with and without recurrence were 8 (7, 12) and 5 (2, 6) respectively. CONCLUSIONS: Episioproctotomy is a successful technique for repair of rectovaginal fistula and cloaca. Incontinence score postoperatively were acceptable. It should be considered a first line of surgical treatment in those with a fistula that includes compromise of the anterior sphincter complex.

Clinical and gastroscopic evaluation of amtolmetin guacyl versus diclofenac in patients with rheumatoid arthritis.

AIM: Amtolmetin guacyl (2-[2[1-methyl-5-(4-methylbenzoyl) pyrrol-2-yl] acetamido] acetic acid 2-methoxyphenyl ester) is a recently developed drug which, in preliminary studies, has shown effective anti-inflammatory properties with improved gastrointestinal safety. Our study was designed to investigate the efficacy and tolerability of amtolmetin guacyl 600 mg bid when compared to diclofenac 50 mg tid for 4 weeks. PATIENTS AND METHODS: A total of 64 patients aged 18-80 years, suffering from rheumatoid arthritis for more than 6 months and American Rheumatism Association functional class I, II or III were randomized in a double blind manner to amtolmetin guacyl or diclofenac for 4 weeks. Clinical and endoscopic evaluation were performed at baseline and at the end of the treatment. The mucosa was graded by means of a rating system emphasizing mucosal erosions. Only patients with endoscopy grade 0-1 entered the trial. RESULTS: The median post-treatment endoscopy injury scores were 0 (range 0-4) in the amtolmetin guacyl-treated patients and 2 (range 0-4) in the diclofenac-treated patients (p = 0.005). There were nine gastric ulcers: 1/32 (3%) in the amtolmetin guacyl group and 8/32 (25%) in the diclofenac group (p < 0.05; 95% confidence interval, -30-5%). 16/32 (50%) patients in amtolmetin guacyl group and 8/32 (25%) in diclofenac group had normal gastroduodenal findings (score = 0) (p < 0.05; 95% confidence interval, 5-50%). In patients with a history of peptic ulcer, a recurrence of gastric damage (score 3-4) was observed in 18% in the amtolmetin guacyl and in 53% in the diclofenac group (p < 0.05). The incidence of gastrointestinal symptoms did not differ in the two groups. Amtolmetin guacyl significantly reduced the number of swollen and painful joints, and the functional disability index; diclofenac significantly reduced the number of painful joints and the functional disability index score (p = ns). CONCLUSIONS: Amtolmetin guacyl effectively controlled the symptoms of rheumatoid arthritis, with very limited gastric toxicity. If these findings are confirmed on a wider scale, the drug might become a valid alternative to current therapies, especially for patients at risk, such as those with rheumatoid arthritis simultaneously requiring steroids and second-line drugs, or those with a history of peptic ulcer.

Adjuvant radiotherapy in patients with pathologic Stage C (pT3N0) adenocarcinoma of the prostate.

OBJECTIVES: This report is an update on the outcomes in the management of pathologic Stage C (T3N0) prostate cancer (CaP) with postoperative irradiation. METHODS: Between 1976 and 1994, 311 patients with pathologic Stage C CaP were treated with radical prostatectomy. Pathologic stage was as follows: C1, 60 patients (19%), C2, 146 patients (47%), and C3, 105 patients (34%). Gleason score was 2 to 4 in 10 patients (3.2%), 5 to 6 in 121 (39%), 7 in 101 (32%), and 8 to 10 in 76 (24%); median prostate-specific antigen (PSA) level was 11.9 ng/mL. Postoperative irradiation consisted of a median dose of 48 Gy. Follow-up was up to 18 years (median 5). RESULTS: The 10-year actuarial survival was 81% and 10-year disease-free survival was 51%. Pathologic stage and Gleason score were independently predictive of recurrence, each with P >0.001 after controlling for the other. Patients with pathologic Stage C3 and Gleason score 7 to 10 were in the worst prognostic category and had 5.4 times the risk of recurrence compared with patients with pathologic Stage C1-C2, Gleason score 2 to 6. Preoperative PSA was a good (P = 0.02) predictor of disease-free survival. Clinical recurrence was seen in 28 patients (9%), including 10 (3.2%) with local recurrence. PSA recurrence (PSA greater than 0.05 ng/mL) developed in 68 patients (22%). CONCLUSIONS: With the known limitations of a nonrandomized clinical trial, on the basis of the experience of this study we recommend the use of moderate dose, limited-field postoperative radiotherapy in patients with pathologic Stage C disease with Gleason score greater than 4.

Histological grading of prostatic carcinoma in prostatectomy specimens. Comparison of prognostic accuracy of five grading systems.

The prognostic accuracy of 5 histological grading systems (Broders, Anderson, Mostofi, Gleason and Mostofi-Schroeder) was compared. Grading was performed on 50 prostatectomy specimens by 5 pathologists. The results were averaged so as to reduce the impact of inter-observer variation. The Cox proportional hazards model was used to estimate the relationship between average grading scores and both time-to-recurrence and time-to-death by prostatic carcinoma. Age at surgery was considered to be a possible confounding factor and adjusted accordingly. The prognostic impact of the 5 grading systems (related to both recurrence and death caused by prostatic carcinoma) was judged by the likelihood ratio (LR) test score (chi 2 distributed with 1 df); for time-to-recurrence for the Mostofi-Schroeder score the LR was 6.54 and for the Gleason system it was 1.79. A stepwise procedure demonstrated that the best prognostic performance was reached with the Mostofi-Schroeder and Broders systems used together (with Mostofi-Schroeder weighted 1.5 times larger than Broders). For time-to-recurrence the median grading result was also used, giving results similar to the mean grading result. For time-to-death from prostatic carcinoma the LR test scores for all grading systems were relatively low. In this analysis the outcome of the Gleason system showed a minimum of prognostic ability, whereas the Broders and Mostofi-Schroeder systems had a reasonable predictive ability. Since the inter-observer variation of the Mostofi-Schroeder system was large, the Broders system is preferable. The restrictions and implications of this study are discussed and a brief review of the prognostic importance of grading of prostatic carcinoma is presented.

Quantification for staging sinusitis. The Staging and Therapy Group.

A method of quantifying the symptoms, radiologic data, and endoscopic findings in extensive sinus disease is proposed. It is intended to enable clinicians to classify patients with extensive sinus disease according to severity of disease and prognostic category. The rubric of extensive sinus disease, for scoring and staging, comprises recurrent acute sinusitis and chronic sinusitis, but not an isolated episode of acute sinusitis. The method assigns simple numeric scores to specific computed tomography findings, elements of surgical history, presence of defining symptoms of sinusitis, and endoscopic appearance. This quantitative system may be rationalized into a staging system.

Assessment of biomarkers in paired primary and recurrent colorectal adenocarcinomas.

PURPOSE: Recurrent colorectal cancers respond poorly to anticancer treatment including radiotherapy. To better understand the biological characteristics of the recurrent colorectal tumor, we investigated various biomarkers regulating cell proliferation and cell loss in paired primary and recurrent colorectal tumor specimens within each individual. METHODS AND MATERIALS: From a total of 11 colorectal adenocarcinoma patients, 22 specimens of paired primary and recurrent tumors were obtained for analysis. Apoptosis was evaluated by TUNEL labeling of apoptotic DNA fragmentation. Other biomarkers including proliferating cell nuclear antigen (PCNA), p53, WAF1, p34cdc2, and cyclins B1 and D1 were analyzed by immunohistochemical stains. RESULTS: PCNA index (PCNAI) showed an increase in 6 and a decrease in 5 recurrent tumors compared to primary tumors. Median PCNAI in primary and recurrent tumors were 33.5 and 48.3, respectively (p = 0.16). In contrast, the apoptotic index (AI) decreased in 9 of 11 recurrent tumors compared to primary tumors. Median AI decreased from 4.3 in primary tumors to 1.4 in recurrent tumors (p = 0.04). The p53 expression increased in more than half of recurrent tumors compared to primary tumors. Mean staining score increased from 0.7 in primary tumors to 1.2 in recurrent tumors (p = 0.059). WAF1 and cyclin B1 did not show significant change. In contrast, both cyclin D1 and p34cdc2 increased significantly in recurrent tumors. These two biomarkers showed increased expression in 8 (cyclin D1) and 7 (p34cdc2) recurrent tumors, respectively, compared to their primary counterparts. Mean staining scores of both biomarkers in recurrent tumors increased by more than twofold compared to those in primary tumors and these differences were statistically significant (cyclin D1, p = 0.007; p34cdc2, p = 0.008). CONCLUSION: This study showed significantly decreased apoptosis in recurrent colorectal tumors compared to their primary counterparts. The underlying regulatory mechanisms included increased expression of p53 and altered cell cycle regulators such as increased cyclin D1 and p34cdc2. With further study, it may be used for developing a new therapeutic strategy for the treatment of recurrent colorectal cancer.

Skin recurrences after breast-conserving therapy for early-stage breast cancer.

PURPOSE: To assess the frequency and prognosis of skin recurrences after breast-conserving therapy (BCT) compared with other breast recurrences. MATERIALS AND METHODS: From 1968 to 1986, 1,624 patients with unilateral stage I or II breast cancer treated with BCT at the Joint Center for Radiation Therapy (Boston, MA) underwent gross tumor excision and received a dose of > or = 60 Gy to the tumor bed. Skin recurrences (SR) were defined as breast recurrences without associated parenchymal disease. An invasive breast recurrence with any parenchymal disease noted clinically or radiographically was scored as an other breast recurrence (OBR). Median follow-up for survivors was 137 months. RESULTS: SR represented 8% (18 of 229) of all breast recurrences and occurred in 1.1% of all patients. The outcome after local recurrence was different for patients with SR and invasive OBR. Patients with SR more frequently had uncontrolled local failure (50%; 9 of 18) than did patients with OBR (14%; 26 of 188) (P = .0007). Forty-four percent (8 of 18) of patients with SR had distant metastasis simultaneously or within 2 months of the recurrence compared with 5% (9 of 188) of invasive OBR patients (P < .0001). For patients without distant metastasis at the time of recurrence, the 5-year actuarial rate of development of distant metastasis was 60% for SR patients compared with 39% for invasive OBR patients (P = .07), and the corresponding 5-year actuarial survival rates beyond the time of local failure were 51% and 79%, respectively (P = .06). CONCLUSION: In contrast to other types of invasive breast recurrence after breast-conserving therapy, skin recurrences are rare and are associated with a significantly higher rate of distant metastasis and uncontrolled local disease as well as a lower rate of survival.

Prediction of recurrence after laparoscopic fundoplication for erosive reflux esophagitis based on anatomy-function-pathology (AFP) classification.

BACKGROUND: The usefulness of the anatomy-function-pathology (AFP) score was examined to evaluate its prediction of recurrence after laparoscopic fundoplication for erosive reflux esophagitis. METHODS: Of the patients undergoing laparoscopic fundoplication for erosive reflux esophagitis of Los Angeles classification grade A or higher from December 1994 to December 2004, 107 who underwent preoperative barium esophagogram, pH monitoring, and endoscopy were selected as subjects. The AFP score was calculated by A, F, and P factor grades of the AFP classification. By comparing patients with and without recurrence, the usefulness of the AFP score for predicting recurrence was examined. RESULTS: Reflux esophagitis recurred in seven patients. No significant difference in age, sex, or A or F factor was observed between the groups, whereas a significant difference was observed in the P factor (p = 0.008). On the other hand, the mean AFP score in the recurrence group was 16.9 +/- 5.3, whereas that in the nonrecurrence group was 8.9 +/- 5.3 (p = 0.0021). Among the patients with a score of 17 points or more (n = 23), recurrence was found in 6 patients (26%). On the other hand, among the patients with a score lower than 17 points (n = 84), recurrence was found in 1 patient, but not in the remaining 83 patients (1%). Sensitivity was thus 85.7% (95% confidence interval [CI], 42.1-99.6), and specificity was 83% (95% CI, 74.2-89.8). The positive predictive value was 26.1% (95% CI, 10.2-48.4), and the negative predictive value was 98.8% (95% CI, 93.5-99.9). Multiple logistic regression analysis was performed, and receiver operating characteristics curves were obtained. The area under the curve for the AFP score was 0.8457, whereas that for the P factor was 0.7907 (p = 0.0045), suggesting that the AFP score may more accurately predict recurrence than the P factor. CONCLUSION: The AFP score may be useful for predicting postoperative recurrence. If surgery is performed when the AFP score is lower than 17 points, the likelihood of postoperative recurrence is expected to be very low.

[Liver transplantation for primary biliary cirrhosis: retrospective analysis of results at a single center].

BACKGROUND AND OBJECTIVE: Currently liver transplantation (LTx) is the only effective curative therapy of end-stage primary biliary cirrhosis (PBC). Recent data have shown a recurrence rate of up to 32%. However, many studies are based on only a small number of patients with a marginal follow-up below 10 years. It was the aim of this study to analyse survival and complication rates after LTx among 100 patients in a long-term follow-up of up to 17 years. PATIENTS AND METHODS: Between 1989 and 2006 data of 115 patients receiving LTx for PBC at the Charité Campus Virchow were retrospectively analysed. The median age of 89 women (84%) and 17 men (16%) was 54 years (25-67). RESULTS: Actuarial patient survival rate after 10 and 17 years was 88% and 83%. 13 patients (12%) died after a median survival time of 42 months (0.5-136). Two of these patients developed organ dysfunction due to recurrence of PBC. In addition, histological recurrence was found in 17 patients (16%) after a median time of 61 months (36-158). Survival analysis of hospital stay, preoperative Child-Pugh score, rejection episodes, PBC recurrence and retransplantation showed no significant results. CONCLUSION: Long-term follow-up of up to 17 years after liver transplantation for primary biliary cirrhosis showed excellent survival rates. Both the amount and severity of postoperative complications and the preoperative Child-Pugh score did not affect the long-time survival rate significantly.
