We report a case of adenocarcinoma of the prostate in a 41-year-old man with 47XXY karyotype (Klinefelter's syndrome) and chronic lymphocytic leukemia. The increased incidence of malignancy in individuals with Klinefelter's syndrome has been well documented for certain neoplasms. Adenocarcinoma of the prostate has not been reported previously in a patient with Klinefelter's syndrome and a 47XXY karyotype. Absence of mosaicism was confirmed by peripheral lymphocyte, skin fibroblast, bone marrow cell and spleen stroma fibroblast cultures. Chronic lymphocyte leukemia, especially the T-cell cytotoxic/suppressive variant, may additionally add to an immunological deficit. Since carcinoma of the prostate, Klinefelter's syndrome and chronic lymphocytic leukemia are common, the lack of a previous report is interesting. Etiological aspects are discussed.

The appearance of a leukemic infiltration of the prostate gland as the first manifestation of a chronic lymphocytic leukemia, followed by an adenocarcinoma of the prostate gland, is exceptional, since only one case has been previously documented. For this reason the authors wish to signal the possibility of a prostatic infiltration in the course of chronic lymphocytic leukemia and insist on the association of this type of leukemia and cancer.

A man with large-cell carcinoma of the lung, cerebral meningioma, occult adenocarcinoma of the prostate, and follicular adenoma of the thyroid developed symptomatic, rapidly progressive hypereosinophilia with abnormalities of eosinophil ultrastructure and bone marrow karyotype (45,X,15q22-). Although the patient's eosinophilia defied strict classification as idiopathic hypereosinophilic syndrome (HES), simple tumor-associated eosinophilia, or eosinophilic leukemia, it appeared to be incited by the lung cancer and quickly acquired malignant independence. The family had an excess of prostate cancer and lymphoproliferative neoplasms.

The vast majority of cancers that involve the prostate are adenocarcinomas of the duct-acinar secretory epithelium. Other cancers, primarily leukemia and lymphoma, can involve the prostate and lead to an abnormal digital examination or elevated serum prostate specific antigen (PSA). The case discussed is that of a 62 year-old male with T12 complete paraplegia who presented with a persistently elevated PSA and was subsequently diagnosed with T-cell lymphoma involving the prostate. Although rare, leukemia and lymphoma involving the prostate should be included in the differential diagnosis of patients being evaluated for adenocarcinoma of the prostate.

Authors present a case of three asynchronous malignancies in man working life-long in chemical industry. Course of diseases and their treatment are described: B chronic lymphatic leukaemia (B-CLL) (age of 55), conventional clear cell renal carcinoma (CRCC) (age of 61) and adenocarcinoma of prostate (CaP) (age of 72). B-CLL treatment was chlorambucil for 2 years and follow-up subsequently. CRCC treatment was radical transperitoneal nephrectomy. Due to locally advanced CaP bilateral orchiectomy and radical external beam radiotherapy were performed. Patients is alive 30 months without any signs of any malignity. Incidence of multiple malignancies and particularly triplicities are discussed in this article. Authors point out pertinence of radical therapeutic approach also in multiple malignancies and oncological screening not only in patients with heamatological malignancy, but considering it in all tumours.

The purpose of The Cancer and Leukemia Group B (CALGB) 90203 trial is to determine which of 2 treatment strategies is superior in treating men with high-risk, clinically localized adenocarcinoma of the prostate (stage T1 to T3a NX M0), defined as a predicted probability < or =60% of remaining free from disease recurrence for 5 years after surgery. Patients with a > or =10-year life expectancy will be randomized to either radical prostatectomy (RP) alone versus estramustine and docetaxel before RP. Participants will be excluded if they have received prior therapy for prostate cancer (except transurethral resection of the prostate) or are judged not to be appropriate candidates for RP. Eligible patients will be stratified according to their predicted probability of remaining free from disease recurrence at 5 years after surgery (0% to 20%, 21% to 40%, and 41% to 60%) and randomized. Neoadjuvant chemotherapy will be 6 cycles (1 cycle = 21 days) of estramustine (280 mg tid, days 1 to 5) and docetaxel (70 mg/m2 on day 2). Warfarin (2 mg/day orally) will be given for prophylaxis against deep venous thrombosis. Bilateral pelvic lymph node dissection and RP will be performed within 60 days of registration/randomization for men randomized to the surgery-alone arm. For men randomized to receive preoperative chemotherapy, the surgical procedure will be performed within 60 days of completion of chemotherapy. Patients will be monitored with history review, physical examination, and serum prostate-specific antigen (PSA) levels every 3 months for the first 3 years after surgery, every 6 months for the next 3 years, and annually thereafter. Biochemical disease recurrence will be defined as a serum PSA level >0.4 ng/mL on 2 consecutive occasions > or =3 months apart after RP. The time of biochemical failure is measured from the date of randomization to the time of the first PSA level <0.4 ng/mL that is confirmed on the second serial PSA. The primary study end point is to determine if early systemic treatment with neoadjuvant estramustine and docetaxel before RP in patients with high-risk prostate cancer will decrease 5-year recurrence rates when compared with RP alone. Secondary outcomes will include (1) the safety and tolerability of neoadjuvant estramustine and docetaxel before RP; (2) the impact of this neoadjuvant strategy on pathologic tumor stage, including lymph node and surgical margin status; (3) time to clinically apparent disease recurrence; and (4) overall survival. The impact of RP with and without neoadjuvant estramustine and docetaxel on the patient's quality of life from pretreatment through year 3 will be assessed. Frozen prostate tissue will be obtained from men undergoing prostatectomy who are enrolled in either the treatment or control arms of the trial. These samples will be analyzed for their RNA expression patterns in order to build outcome prediction models. Furthermore, using array-based methods of expression analysis, the sensitivity to chemotherapeutic agents and response to chemotherapy may likewise be predicted. The trial will enroll approximately 700 men during a 48-month period. Patients will be observed for 84 months after study closure. The power to detect a 36% decrease in 5-year recurrence rates is 90%.

Non-coding RNAs occupy a significant fraction of the human genome. Their biological significance is backed up by a plethora of emerging evidence. One of the most robust approaches to demonstrate non-coding RNA's biological relevance is through their prognostic value. Using the rich gene expression data from The Cancer Genome Altas (TCGA), we designed Advanced Expression Survival Analysis (AESA), a web tool which provides several novel survival analysis approaches not offered by previous tools. In addition to the common single-gene approach, AESA computes the gene expression composite score of a set of genes for survival analysis and utilizes permutation test or cross-validation to assess the significance of log-rank statistic and the degree of over-fitting. AESA offers survival feature selection with post-selection inference and utilizes expanded TCGA clinical data including overall, disease-specific, disease-free, and progression-free survival information. Users can analyse either protein-coding or non-coding regions of the transcriptome. We demonstrated the effectiveness of AESA using several empirical examples. Our analyses showed that non-coding RNAs perform as well as messenger RNAs in predicting survival of cancer patients. These results reinforce the potential prognostic value of non-coding RNAs. AESA is developed as a module in the freely accessible analysis suite MutEx.
