[Plastic reconstructive procedures of vulvar carcinoma: results and complications]. / Plastisch-rekonstruktive Vulvachirurgie -- Ergebnisse und Komplikationen.

PURPOSE: This study describes the results of the plastic reconstructive measures in 207 patients with a primary or a recurrent vulvar cancer. These procedures were analysed in sight of surgical excision, previous therapy, and detailed postoperative results. METHODS: All procedures and clinical parameters were recorded standardized in a data bank and analysed using statistical methods. RESULTS: In 123 local (cutaneous or fasciocutaneous) and 84 regional (myocutaneous) flaps we found a primary healing in about 2/3 of the cases. Local flaps exhibited secondary healing in 31 %, regional flaps in 20 %. This often involved the donor sites and generally did not present any permanent problems. Pronounced healing disturbances (necrosis of more than 10 %) was not achieved in local flaps, in regional flaps it aroused in 5.9 %. Gluteal femoral flaps were used most frequently and showing the best results of all myocutaneous flaps. They were comparable with the local reconstructions by a high degree of reliability and healing. In 15 cases a tissue-loss was observed. In these patients, elevated risk factors, certain oncological characteristics and technical problems could be demonstrated. CONCLUSION: Plastic surgery enlarges the spectrum of operative therapy of vulvar cancer, especially in extensive or recurrent tumors, leading to a favourable oncological outcome and good cosmetic results. Severe healing disturbances are rare and can be controlled.

Reconstructive surgery following resection of primary vulvar cancers.

OBJECTIVE: This study describes the surgical treatment and follow-up of 213 patients with primary vulvar cancer; particular attention is given to reconstructive surgical procedures. METHODS: The clinical and pathological parameters of the patients were recorded according to standardized procedures, and the data concerning type of operation, surgical reconstruction and postoperative course of disease (recurrence-free and overall survival) were analyzed. RESULTS: In about one-third of the cases, plastic surgery reconstruction involving skin-flaps was performed. In the present group of patients, plastic surgery procedures led to an elevated degree of operability as well as to more satisfactory results in terms of wound healing. For minor cosmetic defects, local (fasciocutaneous) skin-flaps resulted in excellent wound healing and short periods of in-patient treatment, even in patients with larger tumors. In cases exhibiting more severe wounds extending over larger areas of the vulva and its surrounding regions, similarly encouraging results were achieved using regional (myocutaneous) skin-flaps. CONCLUSION: The present study shows that reconstructive surgery of the vulva leads to good results in patients with vulvar cancer. Plastic surgery enlarges the spectrum of available operative therapy in vulvar cancer, especially in large tumors, and its application leads to a favorable oncological outcome as well as excellent cosmetic results in patients with vulvar cancer.

Early postpartum hyponatremia in a patient with transient Sheehan's syndrome.

In modern day health care, Sheehan's syndrome is a rare disorder affecting the postpartum period. We present a case of a 33-year-old woman with atonic hemorrhage developing a transient Sheehan's syndrome associated with hyponatremia six days postpartum. Evaluation of cranial computer tomography and magnetic resonance imaging of the pituitary demonstrated normal finding. Immediate replacement therapy using sodium, chloride, hydrocortisone, fludrocortisone and levothyroxine revealed regression of the Sheehan's syndrome to complete recovery. The present report shows that Sheehan's syndrome can be associated with hyponatremia and illustrates the need to include hyponatremia as an initial symptom in the differential diagnosis of Sheehan's syndrome.

p53 expression and resistance against paclitaxel in patients with metastatic breast cancer.

PURPOSE: Paclitaxel is an important agent in the pharmacological treatment of metastatic breast cancer. Despite its efficacy in selected patients, the majority of patients have a resistance against paclitaxel. The aim of this study was to identify the responding patients and hence prevent the other patients from ineffective treatment. Identifying these patients could spare them an ineffective treatment and could in turn characterize a subgroup of patients with a higher response rate. MATERIAL AND METHODS: Thirty-three patients with metastatic breast cancer received paclitaxel 175 mg/m(2 )either as first- (15 patients) or as second-line (18 patients) treatment. Immunohistochemistry was performed on the blocks of the primary tumors with monoclonal antibodies against p53, HER-2/ neu, P-glycoprotein, Glutathione-S-Transferase-pi, and beta-tubulin II. The expression of those factors was then correlated with the objective response to paclitaxel. RESULTS: Ten of 33 patients had an objective response to treatment. A significant correlation with the objective response was found for the expression of p53. None of the tumors with p53 expression ( n=11) responded to paclitaxel. In contrast, 10 of the 22 patients without p53 expression showed an objective response ( P=0.013). Expression of HER-2/ neu, P-glycoprotein, Glutathione-S-Transferase-pi, and beta-tubulin II did not show a correlation with the response to paclitaxel. CONCLUSION: The immunohistochemical detection of p53 characterizes patients with metastatic breast cancer unlikely to respond to paclitaxel.

Multivariate independent prognostic factors in endometrial carcinoma: a clinicopathologic study in 181 patients: 10 years experience at the Department of Obstetrics and Gynecology of the Mainz University.

The aim of this study was to evaluate the biologic outcome of endometrial carcinomas as compared to clinical and pathologic parameters and to identify multivariate independent prognostic factors. Charts were abstracted from patients with endometrial carcinoma from 1985 to 1995. Data on clinicopathologic variables, adjuvant treatment, site of recurrence, and survival were collected. chi2 test was used to test association between variables. Kaplan-Maier method was used for survival analysis and Cox proportional hazards model for multiple regression analysis. Univariate analysis revealed that FIGO stage, tumor grade, depth of myometrial invasion, biochemical analysis of progesterone receptor status, age, additional diabetes mellitus, lymph node metastasis, and type of tumor were significantly associated with the overall-survival. For disease-free interval, FIGO stage, tumor grade, depth of myometrial invasion, biochemical analysis of progesterone receptor status, lymph node metastasis, and type of tumor were also significantly associated. Multivariate analysis revealed that FIGO stage, tumor grading, tumor type, depth of myometrial invasion, and biochemically measured progesterone receptor status were associated significantly with overall survival. A significant correlation as independent prognostic factors were also seen for recurrence free interval for FIGO stage, tumor grade, and biochemical progesterone receptor status. In multivariate statistical analysis we identified FIGO stage, tumor type, tumor grade, biochemical analysis of progesterone receptor status, and depth of myometrial invasion as independent prognostic factors for overall survival, and FIGO stage, biochemical analysis of progesterone receptor status, and tumor grade as independent prognostic factors for recurrence-free interval.

Improved assessment of T-cell receptor (TCR) VB repertoire in clinical specimens: combination of TCR-CDR3 spectratyping with flow cytometry-based TCR VB frequency analysis.

Antigen-specific T-cell responses may be described by combining three categories: (i) the specificity and effector functions of a T-cell population, (ii) the quantity of T-cell responses (i.e., the number of responding T cells within the CD4/CD8 population), and (iii) the "quality" of T cells (defined by the T-cell receptor [TCR] structure). Several methods to measure T-cell responses are now available including evaluation of T-cell precursors using limiting dilution, the enzyme-linked immunospot assay, ex vivo TCR variable (v)-segment analysis determined by flow cytometry, and TCR-CDR3 length analysis (spectratyping), as well as identification of peptide-specific T cells using major histocompatibility complex (MHC) class I tetramers containing appropriate peptides. Until now, only a limited set of MHC-peptide complexes have been available as tetramer complexes. We demonstrate that CD8(+) or CD4(+) T cells in patients with cancer can be molecularly defined using a combination of spectratyping (TCR structure and "molecular composition") plus the implementation of an antibody panel directed against 21 individual VB TCR chains ("quantity" of T-cell families). This approach is instrumental in defining and comparing the magnitudes of CD4(+) or CD8(+) T-cell responses over time in individual patients, in comparing the TCR VA and VB repertoire in different anatomic compartments, and in comparing the TCR VA-VB diversity with that in normal healthy controls. This method provides the means of objectively defining and comparing the TCR repertoire in patients undergoing vaccination protocols and underlines the necessity to calibrate the TCR-CDR3 analysis with a qualitative assessment of individual TCR VB families.

Antigen-driven T-cell selection in patients with cervical cancer as evidenced by T-cell receptor analysis and recognition of autologous tumor.

We characterized the T-cell receptor (TCR) repertoire in freshly harvested tumor lesions, in short-term-expanded CD4(+) tumor infiltrating lymphocytes (TIL) as well as in CD4(+) and CD8(+) peripheral blood lymphocytes (PBL) from three patients with cervical cancer. Skewing of the T-cell repertoire as defined by measuring the length of the complementarity-determining region 3 (CDR3) of the TCR VA and VB chains was observed in CD8(+) PBL, in freshly harvested tumor tissue, as well as in CD4(+) TIL. Comparative analysis of the TCR repertoire revealed unique monoclonal TCR transcripts within the tumor lesion which were not present in PBL, suggesting selection of TCR clonotypes due to antigenic stimulation. TCR repertoire analysis of the short-term (7-day) CD4(+) TIL lines revealed that the TCR composition is markedly different from that in CD4(+) PBL or in the freshly harvested tumor tissue. Only one-third of CD4(+) TIL lines showed HLA-DR-restricted recognition of autologous tumor cells as defined by cytolysis. These data provide support for the antigen-driven selection of T cells within cervical cancer lesions and suggest that analysis of the TCR repertoire may aid in obtaining an objective description of the immune response in patients with cervical cancer who are undergoing epitope-based immunotherapy.

[Valence of immunohistochemical analysis of endometrial carcinoma biopsy specimen]. / Wertigkeit der Abradathistologie von Endometriumkarzinomen.

OBJECTIVE: We compared immunohistological examination of endometrium biopsy specimen with the results of the immunohistological examination of tumor specimen to analyse the valence of this preoperative examination according to the clinico-pathological findings and overall-survival. MATERIAL AND METHOD: Between 1985 and 1995 193 women were treated of an endometrial carcinoma at the University hospital Mainz. In this group we evaluated 41 patients with enough preoperative endometrial biopsy material for a retrospective immunohistochemical analysis and complete follow-up data. The materials from diagnostic curettage were stained and analysed for oestrogen and progesterone receptor status and for MiB-1. The results were statistically analysed using Logrank-test for overall survival. RESULTS: The mean follow-up time was 49 months. We found a significant correlation between staining results of oestrogen (p-value = 0.0005) and progesterone (p-value=0.0003) receptor status with overall survival as well as for MiB-1 (p-value=0.05). The correlation of staining results between biopsy specimen results and tumor material from hysterectomy was 84-85 %. CONCLUSION: These well known prognostic factors are measurable on biopsy specimen material in same quality and high valence as on hysterectomy material.

[Personal Digital Assistants assisting in clinical and administrative tasks]. / Unterstützung klinisch-administrativer Aufgaben durch Personal Digital Assistants (PDAs)--Möglichkeiten und Grenzen.

Personal digital assistants (PDAs) are increasingly used by many professional and private users. They replace and combine common calendars, directories, to-do-lists and much more. Supplemented by useful additional software they can assist the clinician in his daily routine work. This concerns typical medical information as well as administrative work but gets more importance with regard to the planned introduction of diagnosis related groups in Germany however. Exact coding of medical performance is essential for this future invoice system. How PDAs can be used convenient in this respect will be shown with examples from our department.

Perineal excision of a large angiomyxoma in a young woman following magnetic resonance and angiographic imaging.

BACKGROUND: Aggressive angiomyxomas are rare, arise from connective tissue of the perineum or the lower pelvis, and affect predominantly young women. CASE: We describe an unusual case of aggressive angiomyxoma in which the perineal approach was possible owing to MRI scanning and selective angiography indications. CONCLUSION: In cases of large aggressive angiomyxomas these diagnostic procedures should make it possible to decide which operative route might be best for the patient.

[Integrated gynecology: new medical treatments due to psychosomatic methods of evaluation]. / Integrative Frauenheilkunde: neue Behandlungsstrategien dank psychosomatischer Evaluationsmethoden.

OBJECTIVE: Women with gynecologic cancer are confronted with difficult decisions regarding the therapeutic options. The objective of the present paper is to demonstrate the relationship between surgical procedures and the outcome on quality of life and to discuss the implications for patient management. METHODS: Gynecologic patients were assessed in a prospective study with preoperative semistructured interviews and objective assessments (T1), interviews were repeated 4 and 12 months postoperatively (T2, T3). RESULTS: Women planned for hysterectomy with severe complaints indicate a better postoperative quality of life. Cancer patients, however, tend to feel more distressed about the surgical procedure if they could not be treated organ preserving or by reconstructive techniques. Medical interaction is dependent on the patient's anxiety level and mostly important for their quality of life before and after surgery. CONCLUSION: Psychosomatic research is not only necessary to understand the patient's needs before and after surgery but may also serve as an evaluation method of therapeutical options. By this methods we are able to anticipate the medical and psychological consequences of the therapeutic decisions. Future studies will systematically explore the alternating effect of surgical procedures on the patient's well-being.

[Body image in gynecologic patients before and after radical surgery]. / Das Körpererleben gynäkologischer Patientinnen vor und nach radikaler Chirurgie.

After radical gynecologic surgery women are faced with therapy-induced changes of their body. Since 1995, the body images of women who undergo pelvic exenteration, Wertheim-Meigs-operation or hysterectomy are assessed preoperatively and four and twelve months postoperatively. The aim of this multidimensional prospective study is to get basic information for effective counselling and support. One year after hysterectomy women state to have a normal body image. Cancer patients feel less attractive, less self-confident and more discontented in sexuality depending on therapy-induced changes of their bodies. These women could profit from problem-related preoperative counselling. Postoperative counselling offers will be helpful to support women in the process of acceptance of bodily changes and in the reorganisation of their sexual life.

Hypoxia-stimulated expression of angiogenic growth factors in cervical cancer cells and cervical cancer-derived fibroblasts.

It is generally accepted that local growth of solid tumors and their ability to establish distant metastases are dependent on the formation of new blood vessels arising from preexisting ones (angiogenesis). The angiogenic response of the host is mediated by angiogenic molecules that are released from cancer and normal stroma cells, especially fibroblasts. The goal of the present study was to quantitatively compare the expression of the two most important angiogenic growth factors (VEGF, angiogenin) of cervical cancer cells (HeLa and Me-180) with that of cervical cancer-derived fibroblasts (from one tumor/patient) under defined normoxic and hypoxic conditions in vitro. The growth kinetics of cervical cancer cells (HeLa and Me-180) and tumor-derived fibroblasts were evaluated in vitro under normoxic and hypoxic conditions. Growth factor concentrations in the cell culture medium were measured by ELISA and the secretion rates per cell were calculated. Under normoxic conditions, both the cervical cancer cells as well as the tumor-derived fibroblasts released VEGF and angiogenin. The secretion rate of both angiogenic factors was significantly higher in the stroma cells than in the tumor cells (P < 0.05). VEGF and angiogenin secretion is significantly higher in the stroma cells under hypoxia than in the tumor cells investigated (P < 0.05). The presented data support the concept that in cervical cancer non-neoplastic fibroblasts could play a pivotal role in the complex process of tumor angiogenesis.

The presence of HPV DNA in cervical cancer: correlation with clinico-pathologic parameters and prognostic significance: 10 years experience at the Department of Obstetrics and Gynecology of the Mainz University.

The objective of this study was to assess whether the presence of human papillomavirus (HPV) DNA and/or several genotypes of HPV DNA in cervical cancer are correlated with several clinicopathologic parameters of well-defined prognostic significance and whether virologic parameters are predictors of long-term survival in cancer patients. Two hundred twenty three cases of cervical cancer patients included in this retrospective study underwent follow-up evaluation. Survival and cause of death were examined for 204 (91.4%) patients, with a mean follow-up time of 4.4 years. HPV DNA was detected using the highly sensitive polymerase chain reaction (PCR) method followed by HPV DNA sequencing for HPV genotyping. These results were correlated with well-defined clinicopathologic parameters and survival data. HPV DNA was detected by PCR in 150 of 193 (73.4%) tissue specimens of cervical cancer patients. DNA sequence analysis revealed the presence of HPV 16 (n = 68, 45.3%), HPV 18 (n = 49, 32.6%) and rare HPV types (n = 33, 22.1%). HPV genotypes correlated significantly with histologic tumor types, node status, tumor oxygenation, blood vessel invasion, and lymph space involvement. The presence of HPV DNA in cervical cancer as well as the genotype of HPV 16 could also be confirmed as significant prognostic factors in the univariate Cox regression analysis (RR 2.856, P < 0.003 resp. RR 3.444, P < 0.0001). In the multivariate analysis, however, HPV DNA status failed to be of prognostic relevance. Exclusively HPV 16 appears to have an independent impact on the overall survival in cervical patients (RR 3.653, P < 0.002). We conclude that the detection of HPV 16 genotype may play an important adjunct role in assessing prognosis of cervical cancer patients. The clinical impact of the presence of HPV DNA in primary tumors of uterine cervix remains to be investigated in further studies, and the exact mechanisms by which HPV influences the prognosis of cervical cancer patients have to be defined.

Human papillomavirus (HPV) DNA in primary cervical cancer and in cancer free pelvic lymph nodes--correlation with clinico-pathological parameters and prognostic significance.

OBJECTIVE: To assess whether the presence of human papilloma virus (HPV) DNA and/or several genotypes of HPV DNA in primary cervical cancer and cancer free pelvic lymph nodes are correlated with several clinicopathological parameters of well-defined prognostic significance and whether virological parameters are predictors of long-term survival in cancer patients. PATIENTS AND METHODS: 223 cases of cervical cancer patients included in this retrospective study underwent follow-up evaluation. Survival and cause of death were examined for 204 (91.4%) patients, with a mean follow-up time of 4.4 years. HPV DNA was detected using the high sensitive polymerase chain reaction (PCR) method followed by HPV DNA sequencing for HPV genotyping. These results were correlated with well-defined clinicopathological parameters and survival data. RESULTS: HPV DNA was detected by PCR in 150 of 203 (73.4%) tissue specimens of cervical cancer patients. DNA sequence analysis revealed the presence of HPV 16 (n = 68, 45.3%), HPV 18 (n = 49, 32.6%) and rare HPV types (n = 33, 22.1%). HPV genotypes correlated significantly with histological tumor types, node status, blood vessel invasion and lymph space involvement. The presence of HPV DNA in cervical cancer as well as the genotype of HPV 16 could also be confirmed as significant prognostic factors in the univariate Cox Regression Analysis (RR 2.856, p < 0.003 resp. RR 3.444, p < 0.0001). The presence of HPV DNA in cancer free pelvic lymph nodes was significantly correlated to the concomitant manifestation of pelvic lymph node metastases (RR 3.1, p < 0.0001). In the multivariate analysis, however, HPV DNA in primary tumor and in negative pelvic lymph nodes failed to be of prognostic relevance. Exclusively, HPV 16 appears to impact independently on the overall survival in cervical cancer patients (RR 3.653, p < 0.002). CONCLUSION: The detection of HPV 16 genotype may play an important adjunct role in assessing prognosis of cervical cancer patients. The clinical impact of the presence of HPV DNA in primary tumors and cancer free pelvic lymph nodes remains to be investigated in further studies. The exact mechanisms by which HPV influence the prognosis of cervical cancer patients have to be defined.

Metallothionein expression in ovarian cancer in relation to histopathological parameters and molecular markers of prognosis.

Metallothioneins (MTs) and glutathione constitute the major fractions of intracellular thiol factors. Abundant nucleophilic sulfhydryl groups can interact with many electrophilic substances, including several anti-neoplastic agents, participate in controlling intracellular redox potential, and act as scavengers of reactive oxygen species. In the present study, we examined the relation of MTs (alone and in combination with glutathione) to histopathological parameters and survival time of ovarian cancer patients. Expression of the major MT isoforms (MT-1 and MT-2) was determined by immunohistochemistry on paraffin-embedded tumor specimens from 189 patients, 151 suffering from primary epithelial ovarian cancer and 38 from recurrences. MT was negatively associated with survival time when all patients with primary carcinomas (n = 151) were analyzed (p = 0.049, log-rank test). However, no significant association between MT expression and survival was obtained when subgroups of patients with histological grade 1, 2 or 3 carcinomas were analyzed. Similarly, no significant association of MT expression and survival was obtained with the proportional hazards model adjusted for histological grade. This scenario can be explained by a correlation between MT expression and histological grade: MT was detectable in 26%, 48% and 62% of grade 1, 2 and 3 carcinomas, respectively (p = 0.008, chi(2) test). An interesting hypothesis is generated by combined analysis of MT and total glutathione content (GSH). The product of MT and GSH levels (MT x GSH) was negatively associated with survival of grade 1 carcinomas (p = 0.021, log-rank test) but not with grade 2 and 3 carcinomas (p = 0.176 and 0.403, respectively). When MT x GSH was greater than the median, 25% of patients with grade 1 carcinomas died within 235 days. In contrast, all patients with grade 1 carcinomas survived when MT x GSH in tumor tissue was smaller than the median. This suggests that high expression of sulfhydryl factors might facilitate survival and progression of low-grade ovarian cancer cells. A significant correlation was obtained between MT expression and mutant p53 (p = 0.037, chi(2) test). However, this might be an indirect effect since both MT (p = 0.008) and mutant p53 (p = 0.000) were associated with histological grade. In conclusion, MT expression as well as the product of MT and GSH were associated with histological grade of primary ovarian carcinomas. High expression of both sulfhydryl factors may identify a subgroup of low-grade carcinomas with an increased risk of progression.

[Endometrial carcinoma in patients with diabetes mellitus]. / Prognostische Bedeutung einer Diabeteserkrankung beim Endometriumkarzinom.

OBJECTIVE: The purposes of this study were to analyze the relationship between clinical and pathological risk factors in endometrial cancer and additional diabetes mellitus and to clarify the correlation between additional diabetes mellitus and survival of patients with this disease. - MATERIAL AND METHODS: This analyze included 181 patients with endometrial carcinoma who were treated between 1985 and 1995 at the University hospital Mainz. Patients with sarcoma were excluded. For statistical analysis a chi(2)-test was performed for univariat analysis. A Kaplan-Meier procedure was performed for over all survival and disease free interval and COX-Regression for multivariate analysis of independence. - RESULTS: The mean follow-up period was 49 months. The mean age was 65 years. 21.8 % of the patients had an additional diabetes mellitus. These patients had a significantly deeper infiltration of the Myometrium (p-value = 0.004) and were more likely to have lymphonode metastasis (p-value = 0.02). - CONCLUSION: Our results show a correlation between Diabetes mellitus and adverse prognostic factors witch affects by the rate of lymphonode spread and overall survival.

(A)symptomatic necrotizing arteritis of the female genital tract.

AIMS: The vasculitides represent a heterogenous set of disorders that differ in prognosis and response to therapy. Beside systemic vasculitides, the development of localized forms of arteritis is well known though uncommon and the etiopathogenesis is not yet definitely clear. METHODS: Patients with necrotizing arteritis of the female genital tract proven by histology are studied in a retrospective analysis. RESULTS: Three cases of necrotizing arteritis with histological features of panarteritis nodosa apparently confined to the female genital tract are presented. None of these patients had prior history of systemic vasculitis. The acute necrotizing vasculitis was confined only to the uterine cervix in two patients and involved all the internal genital organs in the third patient. The patients have been observed for up to 4 years without any therapy for these lesions and without any manifestation of systemic vasculitic progression. CONCLUSION: It is to speculate that focal arteritis of the female genital tract is a benign form of panarteritis nodosa or moreover a totally different entity with identical morphogenesis but possibly different pathogenesis. Furthermore it seems to be important to be aware of the specificity of focal arteritis in female genital tract as distinct from the generalized form to prevent unnecessary surgical or chemotherapeutical therapy for this lesion. The benign entity of local arteritis in the female genital tract is discussed in contrast to the severe prognosis of systemic panarteritis nodosa.

[Integration of quality assurance procedures into medical documentation systems--from quality indicator to improved medical quality]. / Die Integration qualitätssichernder Prozeduren in medizinische Dokumentationssysteme--vom Qualitätsindikator zur verbesserten medizinischen Qualität.

Medical and commercial data are essential for sufficient clinical management. While regional quality studies--for example the German Perinatal Data Study--are mighty tools to compare the quality of departments in total--the integration of evaluated individual quality indicators in data processing systems can highly improve clinical results and clinical management. The evaluation of quality indicators improves the benefit of quality management. Parameters monitoring the contentment of patients are extremely valuable information. Quality management and information management are closely linked.
