ABSTRACT

BACKGROUND: Testicular microlithiasis is the presence of small calcifications in the testicular parenchyma. The association between testicular microlithiasis and germ cell neoplasia in situ, a precursor to testicular cancer, is still unclear. OBJECTIVES: To determine the incidence of germ cell neoplasia in situ in men with testicular microlithiasis and evaluate the indication for testicular biopsy according to risk factors in the form of male infertility/reduced semen quality, testicular atrophy, and history of cryptorchidism. MATERIALS AND METHODS: This retrospective case series included all patients diagnosed with testicular microlithiasis who underwent testicular biopsies at three hospitals in Denmark between 2007 and 2021. The medical records of 167 patients were reviewed, and data on patient demographics, testicular microlithiasis characteristics, risk factors, histological findings, and treatments were collected. The main outcome measure was the incidence of germ cell neoplasia in situ in relation to each risk factor. The data were analyzed using descriptive statistics. Logistic regression was used to examine the odds ratio of germ cell neoplasia in situ in patients with testicular microlithiasis and testicular atrophy. RESULTS: Germ cell neoplasia in situ was found in 13 out of 167 patients (7.8% [95% confidence interval: 4.3, 13.2]). Eleven of these had testicular atrophy resulting in a significantly higher incidence in this group than other risk factors (odds ratio 9.36 [95% confidence interval: 2.41, 61.88]; p = 0.004). DISCUSSION: The study comprises the largest cohort to date of men who have undergone testicular biopsies because of testicular microlithiasis and additional risk factors. Limitations include its retrospective design, and relatively low absolute numbers of patients with germ cell neoplasia in situ on biopsies. CONCLUSION: This study found that men with testicular microlithiasis and testicular atrophy are at an increased risk of germ cell neoplasia in situ. Additionally, our results indicate that biopsies should be considered in men with a combination of subfertility and bilateral testicular microlithiasis. Our findings do not support testicular biopsies for men with testicular microlithiasis and other risk factors.

ABSTRACT

PURPOSE: To evaluate the effect of lymphadenectomy (LND) in conjunction with nephroureterectomy on cancer-specific mortality (CSM) and overall survival (OS) for patients with muscle-invasive UTUC. METHODS: A retrospective, multicenter study of patients with UTUC, clinical stage N0M0, who underwent nephroureterectomy between January 2008 and December 2014 was conducted. Outcome measures were OS and CSM. RESULTS: In total, 298 patients underwent robot-assisted or laparoscopic radical nephroureterectomy with a final histological diagnosis of UTUC. LND was performed in 46 (15.4%). One hundred and seventy-two patients (62%) had non-muscle-invasive disease (NMID); 105 patients (38%) had muscle-invasive disease (MID). Median time of follow-up was 43.5 months (95% CI 36.0-47.2). For patients with MID, the 5-year cumulative incidence of all-cause mortality and CSM was 73.5% (95% CI 60.4-86.6) and 52.4% (95% CI 38.9-65.9), respectively (p < 0.0001). There was no significant difference in OS between patients with N1 and patients with N0 disease (p = 0.53). The 5-year OS rates were 30.5% (95% CI 6.6-54.4) and 25.7% (95% CI 10.9-40.5), respectively. This study is limited by its retrospective nature. There may also have been bias in the selection of patients undergoing LND. CONCLUSIONS: Five-year OS and CSM are comparable between patients with N1 and N0 MID. This evidence may support the use of the LND procedure in patients with muscle-invasive UTUC.

ABSTRACT

Inguinoscrotal bladder herniation (ISBH) is rare and often asymptomatic, but complications such as renal failure can occur. We present a case of a 70-year-old man with hydrocele. A bone scan showed tracer accumulation in the left scrotum, and a SPECT/CT while urinating revealed that most of the bladder was in the scrotum. Renal function was normal and a cystoscopy was done. The patient did not want surgery. Hydrocele has not been described as the primary cause of referral in patients with ISBH. It is important to diagnose ISBH because of the risk of complications and risk of underlying malignancy.

ABSTRACT

INTRODUCTION: An important prognostic factor in head and neck melanoma is the status of the regional lymph nodes since the presence of metastatic disease in the nodes greatly aggravates the prognosis. There is no consensus on the surgical treatment algorithm for this group. Our aim was to study if there is a difference in nodal recurrence and survival after radical, modified or selective neck dissection. METHODS: A total of 57 patients treated for regional meta-stases of head and neck melanoma were analysed retrospectively with respect to type of neck dissection, use of sentinel node biopsy, nodal recurrence and survival. RESULTS: After a median 127-month (range: 22-290) follow-up period, we showed that there was no significant difference in nodal recurrence between three different dissection groups (11% for radical node dissection, 24% for modified radical node dissection and 23% for selective node dissection, p > 0.05). No significant difference in five-year survival was observed between the dissection types (56% for radical node dissection, 61% for modified radical node dissection and 48% for selective node dissection, p = 0.613). Multivariate and univariate analysis revealed that patients with metastatic deposits in sentinel nodes had a better survival than patients with clinically palpable nodes (five-year survival rate: 70% versus 36%, p = 0.008). CONCLUSION: The extent of neck dissection does not significantly influence the rate of recurrence or survival. This study indicates that there is a survival benefit for patients who undergo completion lymph node dissection following a positive sentinel node biopsy. FUNDING: not relevant. TRIAL REGISTRATION: not relevant.
