Hypogonadism is defined as an array of symptoms arising from a deficiency of androgens. It is caused by a hormonal and spermatogenic dysfunction of the testes. It results in impaired fertility and has a negative impact on the functions of multiple organs and systems, physical well-being, sexual functions and also mental state. Particularly patients with a history of cancer have a high risk of developing hypogonadism as a result of not only the nature of the disease, but mainly its treatment. While leaving the patient with cancer without treatment does not fall within the concept of the art of medicine and the ethical canon of a physician, the symptoms of hypogonadism are often ignored and left untreated...

Intraductal carcinoma of the prostate (IDC-P) is associated with poor prognosis. While it is often regarded as a rare pathology, the prevalence of IDC-P remains unclear, with variable reports from small and disparate patient populations. To determine how common IDC-P is across the spectrum of prostate cancer, we conducted a systematic review correlating IDC-P prevalence with prostate cancer risk. Electronic searches of the OVID Medline, PubMed, and Scopus literature databases identified 38 patient cohorts in 24 articles, which were divided between four prostate cancer risk categories (low, moderate, high, and recurrent or metastatic disease)...

BACKGROUND: Thyroid cancer (TC) is the most common endocrine malignancy. TC patients have a good prognosis and a low disease-related mortality rate. Since the patients are often young, they may be at a higher risk for a second primary malignancy (SPM). We sought to determine the incidence, risk and types of SPM between 1980-2011, and to assess SPM trends over time among Israeli TC patients. METHODS: Data were derived from the Israel National Cancer Registry. Primary TC patients diagnosed during 1980-2009 were followed-up for SPM incidence until December 31, 2011...

An 84-year-old man was diagnosed with two synchronous adenocarcinomas, a Borrmann type IV advanced gastric adenocarcinoma in his antrum and a well-differentiated Borrmann type I carcinoma on the anterior wall of the higher body of his stomach. Pre-operatively, computed tomography of the abdomen revealed the presence of advanced gastric cancer with peri-gastric and para-aortic lymph node (LN) metastasis. He planned for palliative total gastrectomy owing to the risk of obstruction by the antral lesion. We performed a frozen biopsy of a para-aortic LN during surgery and found that the origin of the para-aortic LN metastasis was from undiagnosed prostate cancer...

Prostate cancer can be diagnosed as an incidental finding during the pathological examination of benign prostatic hyperplasia (BPH) specimens by Holmium laser enucleation of the prostate (HoLEP). BPH and comorbidities such as hypertension, diabetes, and dyslipidemia often coexist in elderly people. We identified which comorbidities can be used to predict the presence of incidental prostate cancer, particularly high-risk cancer, in men who had undergone HoLEP. On the basis of pathological findings of HoLEP specimens, patients with incidental cancer were categorized as low-risk (Gleason ≤6 and T1a) or high-risk (all others)...

BACKGROUND: Phase 3 trials have demonstrated a benefit from adjuvant radiation therapy (ART) for men who have adverse factors at radical prostatectomy (RP). However, some patients have a high risk of progression despite ART. The role of systemic therapy with ART in this high-risk group remains to be defined. METHODS: Patients who had either a post-RP prostate-specific antigen (PSA) nadir > 0.2 ng/mL and a Gleason score ≥7 or a PSA nadir ≤0.2 ng/mL, a Gleason score ≥8, and a pathologic tumor (pT) classification ≥ pT3 received 6 months of androgen-deprivation therapy (ADT) plus radiotherapy and 6 cycles of docetaxel...

PURPOSE OF REVIEW: In men on active surveillance for localized prostate cancer, MRI and MRI-targeted biopsies can be used prior to confirmatory or surveillance biopsy, to detect individuals with high-grade cancer (the wolf in sheep's clothing). However, some men will have low-risk disease despite adverse MRI findings (the sheep in wolf's clothing). We review the value addition of MRI-targeted biopsies in comparison to systematic transrectal ultrasound-guided biopsies, using pathological reclassification as an end-point...
