Breast cancer characteristics-comparison of preoperative and postoperative values.

Breast cancer characteristics obtained at the time of diagnosis are important for setting the basic strategy of the treatment. Reliability of preoperative investigation differs for various features of the disease. The aim of this study was to ascertain the agreements and differences between preoperative and postoperative values. This retrospective study analyzed the results of 617 women with primary surgery of the breast and axilla. Cohen's kappa coefficient has been employed to measure the degree of agreement between preoperative and postoperative values. Substantial or "almost perfect" agreement has been documented for the histological type of the tumors, their histopathological grade, proliferation index Ki67, as well as for estrogen, progesterone, and HER-2/neu receptors. Substantial differences exist between preoperative and postoperative diagnoses of invasiveness of the tumor, determination of the size of the tumors, and the number of tumor foci. Preoperative imaging and clinical examination of lymph nodes exhibited unacceptably high false negative rates. Heterogeneity of breast cancer cell population, methodology of histology examinations, and insufficient imaging of lymph nodes are the major limitations precluding satisfactory accuracy of preoperative diagnosis. Preoperatively diagnosed in situ carcinomas, as well as multifocal lesions, were the most often sources of diagnostic failures.

A multicenter, randomized, prospective, controlled study comparing sacrospinous fixation and transvaginal mesh in the treatment of posthysterectomy vaginal vault prolapse.

OBJECTIVE: The objective of the study was to compare recurrence and complication rates for sacrospinous fixation (SSF) and prolene mesh techniques for the primary treatment of posthysterectomy vaginal vault prolapse. STUDY DESIGN: Patients undergoing surgery for vault prolapse were included in a multicenter, randomized, controlled study comparing SSF or total mesh (Prolift; Gynecare/Ethicon, Somerville, NJ). The examination included pelvic organ prolapse quantification, urodynamics, ultrasound, and quality-of-life (QoL) questionnaires before and 3 and 12 months after surgery. RESULTS: Of 168 randomized patients, 83 underwent SSF and 85 mesh repair. Prolapse recurrence after 12 months occurred in 39.4% of the SSF group and in 16.9% of the mesh group (P = .003). The mesh exposure rate was 20.8%. No difference in QoL improvement as well as of de novo stress urinary incontinence and overactive bladder onset was found. CONCLUSION: Mesh exposure occurrence was balanced against a lower prolapse recurrence rate in the patients undergoing mesh surgery compared with those undergoing SSF.

Sentinel lymph node biopsy in breast cancer patients treated with neoadjuvant chemotherapy.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is a widely used staging method for patients with early breast cancer. Neoadjuvant chemotherapy modifies the anatomical conditions in the breast and axilla, and thus SLNB remains controversial in patients treated preoperatively. The aim of this study was to demonstrate the reliability and accuracy of this procedure in this particular group of patients. METHODS: The retrospective study analyzed medical records of patients diagnosed with primary breast cancer between the years 2005 and 2009. Of the patients treated by neoadjuvant therapy, 343 underwent lymphatic mapping to identify sentinel lymph nodes, and these were included in the analysis. RESULTS: The overall detection rate of sentinel lymph nodes was 80.8%. It was strongly influenced by clinical lymph node status (significantly higher success rate in lymph node-negative patients); higher detection rates were also associated with age <50 years, estrogen receptor positivity, lower proliferation index, and absent lymphovascular space invasion. The false-negative rate was 19.5% and was only marginally significantly dependent on lymphovascular space invasion. The overall accuracy of the method was 91.5%. CONCLUSIONS: By using the present technique, sentinel lymph node biopsy cannot be recommended as a reliable predictor of axillary lymph node status when performed at the authors' institution after neoadjuvant chemotherapy. Infrequent use of blue dye for lymphatic mapping, low number of resected sentinel lymph nodes, and absence of any selection among patients included in the study could be the main factors responsible for the low detection rate and high false-negative rate.

Comparison of labor course and women's sexuality in planned and unplanned pregnancy.

OBJECTIVE: This study compares several parameters of sexual life and course of labor in women with planned and unplanned pregnancy. METHODS: 339 primiparas participated in our study; they filled in a questionnaire concerning their sexual life during pregnancy on the second or third day after the delivery. One question also stressed planning of pregnancy. 246 women (i.e., 72.6%) indicated planned pregnancy, 93 pregnancies (i.e., 27.4%) were not planned. RESULTS: Significant decrease of coital activity and number of orgasms and increase of sexual dysfunctions were observed in the whole study group during pregnancy. Significant differences between women with planned and unplanned pregnancy were observed only in frequency of vaginal dryness and pelvic pain. CONCLUSIONS: According to the results of this study, unplanned pregnancy has no adverse effect on parameters of the labor. The equal rate of partner's presence at delivery shows a high involvement of the partners of unmarried women.
