CA125 is currently the most widely used tumor marker for ovarian epithelial cancer. The aim of this article is to provide guidelines for the routine clinical use of CA125 in patients with ovarian cancer. Due to lack of sensitivity for stage I disease and lack of specificity, CA125 is of little value in the detection of early ovarian cancer. At present, therefore, CA125, either alone or in combination with other modalities, cannot be recommended for screening for ovarian cancer in asymptomatic women outside the context of a randomized controlled trial. Preoperative levels in postmenopausal women, however, may aid the differentiation of benign and malignant pelvic masses. Serial levels during chemotherapy for ovarian cancer are useful for assessing response to treatment. Although serial monitoring following initial chemotherapy can lead to the early detection of recurrent disease, the clinical value of this lead-time is unclear. CA125 is the ovarian cancer marker against which new markers for this malignancy should be judged.

Background: Carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), and CYFRA 21-1 are the most useful markers for non-small cell lung cancer (NSCLC), but neuron-specific enolase (NSE) is a tumor maker of choice for SCLC. The determination of NSE in NSCLC could allow selection of patients with neuroendocrine features. NSCLC patients whose tumors have neuroendocrine properties may be more responsive to chemotherapy; however, these tumors have been reported to be more aggressive. Tumor markers are not suitable for diagnosis; their principal applications are in monitoring of therapy and prognosis. Methods: Tumor markers were measured in 200 untreated patients with squamous cell lung cancer (SQC) and a reference group (n = 220; 124 healthy persons and 96 patients with nonmalignant lung disease). CEA and SCC-Ag were measured by microparticle enzyme immunoassays on Abbott AxSYM and IMx analyzers. CYFRA 21-1 and NSE were measured by electrochemiluminescence immunoassays on the Roche Elecsys 2010. Results: CEA, SCC-Ag, CYFRA 21-1, and NSE were increased above the cutoffs in 26%, 32%, 67%, and 28% of tested patients, respectively. The area under the ROC curve for CYFRA 21-1 was higher than those for CEA, SCC-Ag, and NSE (SQC vs controls). CYFRA 21-1 and CEA were significantly higher in advanced SQC than in early stages of disease (P <0.0001 and P <0.0004, respectively). In multivariate analysis of survival, CYFRA 21-1 was an independent but nonspecific prognostic factor in the operable group of SQC patients, whereas NSE was an independent prognostic factor in the advanced stages of disease. Conclusion: CYFRA 21-1 is an independent prognostic factor in earlier stages and NSE in the advanced stages of SQC.

ObjectiveTo present an update of the European Group on Tumor Markers guidelines for serum markers in epithelial ovarian cancer.MethodsSystematic literature survey from 2008 to 2013. The articles were evaluated by level of evidence and strength of recommendation.ResultsBecause of its low sensitivity (50–62% for early stage epithelial ovarian cancer) and limited specificity (94–98.5%), cancer antigen (CA) 125 (CA125) is not recommended as a screening test in asymptomatic women. The Risk of Malignancy Index, which includes CA125, transvaginal ultrasound, and menopausal status, is recommended for the differential diagnosis of a pelvic mass. Because human epididymis protein 4 has been reported to have superior specificity to CA125, especially in premenopausal women, it may be considered either alone or as part of the risk of ovarian malignancy algorithm, in the differential diagnosis of pelvic masses, especially in such women. CA125 should be used to monitor response to first-line chemotherapy using the previously published criteria of the Gynecological Cancer Intergroup, that is, at least a 50% reduction of a pretreatment sample of 70 kU/L or greater. The value of CA125 in posttherapy surveillance is less clear. Although a prospective randomized trial concluded that early administration of chemotherapy based on increasing CA125 levels had no effect on survival, European Group on Tumor Markers state that monitoring with CA125 in this situation should occur, especially if the patient is a candidate for secondary cytoreductive surgery.ConclusionsAt present, CA125 remains the most important biomarker for epithelial ovarian cancer, excluding tumors of mucinous origin.

The aim of this study was to investigate the effect of short-term, moderate intensity and low volume endurance training on gonadal hormone profile in untrained men. Fifteen young, healthy men performed an endurance training of 5-week duration on a cycle ergometer. Before and after the exercise program all participants completed a maximal incremental test. Concentration of testosterone (T), sex hormone-binding globulin (SHBG) and cortisol (C) as well as blood morphology were determined in venous blood samples at rest both before and after the training. The training program resulted in 3.7% improvement of maximal oxygen uptake (VO(2max)) and 8.2% improvement of power output reached at VO(2max) (PO (max)). This was accompanied by significant increase in T (from 18.84+/-5.73 nmol.l(-1) to 22.03+/-6.61 nmol.l(-1), p = 0.0004) and calculated fT concentration (from 374+/-116 pmol.l(-1) to 470+/-153 pmol.l(-1), p = 0.00005). Moreover, the training caused a significant decrease in SHBG concentration (from 34.45+/-11.26 nmol.l(-1) to 31.95+/-10.40 nmol.l(-1), p = 0.01), whereas no significant changes were found in the cortisol concentration (334+/-138 nmol.l(-1) vs. 367+/-135 nmol.l(-1) for pre- and post-training measures, respectively, p = 0.50) and T/C and fT/C ratios. We have concluded that short-term, moderate intensity and low volume endurance training can significantly increase testosterone concentration in previously untrained men.

BackgroundHere, the treatment methods and results of patients with phyllodes tumor of the breast (PT) with distant metastases at a single institution are presented.MethodsA retrospective analysis was performed on a group of 295 patients with PT treated from 1952 to 2010.ResultsDistant metastases developed in 37 (12.5 %) patients; 3/160 (1.9 %) patients had benign PT, 6/36 (16.7 %) were considered borderline, and 28/99 (28.3 %) had malignant PT. Most frequently, the metastases were located in the lungs; 28 (75.7 %), bone 7 (18.9 %), brain 4 (10.8 %), and liver 2 (5.4 %). Metastases occurred on overage 21 months (2–57) after surgery. Patients with lung metastases were generally treated with monochemotherapy or polychemotherapy. In one patient Testosterone and in two patients resection of metastases combined with Doxorubicin were used. Patients with bones or brain metastases were treated with palliative radiotherapy only or combined with Doxorubicin. The mean survival (MS) from diagnosis of distant metastases (DM) was 7 months (2–17). The longest mean survival in patients with bones metastases was 11.8 months, the worst survival was for patients with brain metastases—2.8 months. Hormone therapy appeared to have low efficacy (MS: 2 months) as well as monochemotherapy (MS: 3–5 months). Improved MS was obtained using Doxorubicin (7 months) and Doxorubicin with Cisplatin, Cyclophosphamide, or Ifosfamide (9 months).ConclusionThe prognosis of patients with DM from PT is poor. The role of surgery and irradiation of such patients is very limited. There appears to be no role for the use of hormone therapy. This study showed that polychemotherapy with Doxorubicin and Ifosfamide suggest that it might be more effective than once thought.
