Examination of clinical data and semen analysis results of patients undergoing orchiectomy for testicular tumor

SUMMARY OBJECTIVE: Testicular tumor constitutes 1% of male neoplasms. Infertility can be determined in patients with testicular tumors before orchiectomy due to the deterioration of spermatogenesis. The aim of this study was to show the clinical, radiological, and pathological characteristics and spermiogram results of patients with testicular tumor and their relationship with each other. METHODS: The data of patients who underwent orchiectomy due to testicular tumor between 2016 and 2019 were reviewed retrospectively. These data included sociodemographic data of the patients, pretreatment spermiogram characteristics, level of serum tumor markers, characteristics of the ultrasonography, type of orchiectomy, and histopathological examination. RESULTS: This study included 53 male patients, with a mean age of 33.51±12.86 years. The mean levels of all tumor markers were above the reference levels. The mean tumor size was 34.68±23.32 mm. Multiple localizations and microlithiasis were detected in 11.3 and 13.2% of the tumors, respectively. The most common masses were hypoechoic (n=37; 69.8%) and hypervascular (n=47; 81%). Spermiogram and cryopreservation were performed in 29 (54.7%) of 53 patients preoperatively. The mean sperm concentration before orchiectomy was 24.21×106 /mL and group A sperm motility 0.79%, group B sperm motility 39.10%, group C sperm motility 9.83%, and group D sperm motility 22.69% in testicular tumors. CONCLUSION: Spermatogenesis adversely affected before the treatment due to local and systemic effects of testicular cancer. Fertility expectations can be increased in the subsequent years by semen analysis and referral to cryopreservation.

The relationship of neutrophil to lymphocyte ratio with testicular cancer

ABSTRACT Purpose: To assess the relationship between testicular germ cell tumors (TGCT) and neutrophil to lymphocyte ratio (NLR) and to determine whether this ratio can be used as a serum tumor marker. Material and Methods: Sixty-one patients with testicular germ cell tumors were included into the study. Patients were grouped as localized and non-localized. Histologically patients were categorized as seminoma and nonseminomatous germ cell tumors. Complete blood cell count was measured the day before surgery and at the postoperative 1st month. Preoperative and postoperative mean NLR values were compared. Results: Thirty-six patients (59%) had seminomas and 25 patients (41%) had nonseminomatous testicular cancer. Forty-five patients (73.8%) had localized and 16 patients (26.2%) had non-localized testicular cancer. There was a statistically significant difference between preoperative and postoperative mean NLR of the localized patients (p=0.001) but no such difference was detected for non-localized patients (p=0.576). Nineteen patients with localized seminomas had normal preoperative serum tumor markers. There was a significant difference between preoperative and postoperative mean NLR in this group of patients (p=0.010). Twenty-six patients with localized tumors had preoperative increased serum tumor markers which normalized after orchiectomy. Mean NLR of these patients significantly decreased from 3.10±2.13 to 1.62±0.59 postoperatively (p=0.010). Conclusions: NLR appears to be a useful marker for TGCT. It is successful in predicting localized and non-localized disease in early postoperative period.

Metástasis retroperitonal gigante de un tumor del saco de Yolk / Giant retroperitonal metastasis from a Yolk sac tumor

RESUMEN Paciente con antecedentes de cirugía de tumor testicular, con biopsia de tumor de saco de Yolk y con diagnóstico de un tumor metastásico retroperitoneal irresecable. Un año más tarde de este último diagnóstico es remitido a nosotros, con un aumento considerable de dicha lesión y se logra su exéresis satisfactoriamente. Se realizó una revisión de la literatura, las indicaciones y técnicas en el tratamiento de la metástasis retroperitoneal de un tumor del saco de Yolk y se presentan los resultados de un paciente diagnosticado e intervenido en el Hospital Clínico Quirúrgico "Hermanos Ameijeiras", en el año 2016. La diseminación metastásica retroperitoneal del tumor del saco de Yolk es poco frecuente, muy poco reportado a nivel mundial y con pocas experiencias en su tratamiento. Se realizó una técnica de resección de una lesión gigante con quimioterapia adyuvante posoperatoria. No hubo complicaciones relacionadas con el proceder(AU)

ABSTRACT Patient with a history of testicular tumor surgery, with a Yolk sac tumor biopsy and with a diagnosis of an unresectable retroperitoneal metastatic tumor. One year after this last diagnosis, he was referred to us, with a considerable increase in this lesion and his excision was successfully achieved. A review of the literature, indications and techniques for the treatment of retroperitoneal metastasis from a Yolk sac tumor was performed, and the results of a patient diagnosed and operated on at the "Hermanos Ameijeiras" Clinical Surgical Hospital, in the year 2016. Retroperitoneal metastatic spread of Yolk sac tumor is infrequent, very little reported worldwide and with few experiences in its treatment. A giant lesion resection technique was performed with postoperative adjuvant chemotherapy. There were no complications related to the procedure(AU)

Novel homozygous mutation in a colombian patient with persistent müllerian duct syndrome: expanded phenotype

ABSTRACT The anti-Müllerian hormone triggers the regression of uterus and fallopian tubes in male embryos; if there are problems in the synthesis or action of this protein, Müllerian structures persist in an otherwise phenotypic male. The most frequent clinical presentation of Persistent Mullerian Duct syndrome is cryptorchidism and inguinal hernia. The few cases reported in adults are incidental findings or inguinal hernias. However, we present an adult male with history of bilateral cryptorchidism with unsuccessful orchidopexy, who presents with a large abdominal mass with the finding of a seminomatous tumor and persistence of Müllerian structures, in whom the variant c.916delC (p.Leu306Cysfs*29) in the AMHR2 gene not previously reported was documented.

Spontaneous gas in a retroperitoneal mass: check the testis!

ABSTRACT Testicular germ cell tumor is the most common cancer in 20-to 35-years-old men. There are known risk factors such as undescended testicle(s) and history of testicular cancer. Most lesions are germ cell tumors with two main subtypes: seminomas and non-seminomatous germ cell tumors.

Liposarcoma del cordón espermático simulando una hernia inguinal incarcerada / Liposarcoma of the spermatic cord mimicking an incarcerated inguinal hernia

INTRODUCCIÓN: Los tumores paratesticulares representan del 7%-10% de las masas intraescrotales. Los sarcomas abarcan el 90% de las lesiones malignas del cordón espermático y de éstas, aproximadamente, el 3%-7% son liposarcomas. CASO CLÍNICO: Presentamos el caso de un varón de 45 años, que consultó en urgencias por una masa inguinoescrotal derecha no reductible, diagnosticándose de hernia inguinal incarcerada. Se realizó cirugía urgente evidenciando una gran tumoración de aspecto lipomatoso, dependiente de cordón espermático. Se realizó orquiectomía y hernioplastía inguinal. La anatomía patológica, reveló un liposarcoma bien diferenciado de cordón espermático. Posteriormente, se realizó estudio de extensión, sin afectación a distancia y no precisó tratamiento adyuvante. Actualmente, tras dos años de seguimiento no ha presentado recidiva. DISCUSIÓN: Sólo alrededor de 200 casos han sido comunicados previamente en la literatura y sólo 61 de éstos se presentaron simulando una hernia inguinal incarcerada. Debido a la baja incidencia de esta patología es difícil de conocer la historia natural y llegar a conclusiones sobre los resultados del tratamiento, el cual hasta el momento sigue siendo la orquiectomía radical, con escisión amplia de los tejidos locales. El papel de la radio y quimioterapia aun es controvertido. CONCLUSIONES: Los sarcomas del cordón espermático son neoplasias raras con alta tasa de recurrencia local. Su manejo inicial es quirúrgico. Se requiere de un alto índice de sospecha clínica para el diagnóstico ya que las implicaciones oncológicas varían en función del tratamiento que, en ocasiones, es llevado a cabo por cirujanos generales al simular una hernia inguinal.

INTRODUCTION: Paratesticular tumors represent 7%-10% of intraescrotal masses. Sarcomas account for 90% of malignant lesions of the spermatic cord and of these approximately 3%-7% are liposarcomas. CLINICAL CASE: This is the case of a 45 year old male who consulted in the emergency department for a non-reducible right inguino-scrotal mass and was diagnosed with an incarcerated inguinal hernia. Emergency surgery was performed which revealed a large lipomatous tumor, originating from the spermatic cord. Orchiectomy and hernioplasty were performed. Histopathology revealed a well-differentiated liposarcoma of the spermatic cord. Later extension study was conducted, without distant affectation, and did not require adjuvant treatment. Today, after two years of monitoring has been no recurrence. DISCUSSION: Only about 200 cases have been previously reported in the literature and only 61 of these were presented mimicking an incarcerated inguinal hernia. Due to the low incidence of this disease it is difficult to know the natural history and draw conclusions on the results of treatment, which so far remains the radical orchiectomy with wide local excision of the tissue. The role of radiotherapy and chemotherapy is still controversial

Early development of a gonadal tumor in a patient with mixed gonadal dysgenesis

SUMMARY A gonadal tumor was diagnosed in the first months of life in a patient with genital ambiguity, a 45,X/46,XY karyotype, and mixed gonadal dysgenesis. Gonadal biopsies at the age of 3 months revealed dysgenetic testes and a gonadoblastoma on the right testis. Even though gonadal tumors are rare in childhood, this case indicates that prophylactic removal of dysgenetic gonads should be performed as early as possible, especially when the female sex is assigned to a patient with a Y-chromosome sequence.

Antioxidant enzyme profile and lipid peroxidation products in semen samples of testicular germ cell tumor patients submitted to orchiectomy

ABSTRACT Purpose To determine enzymatic antioxidant and lipid peroxidation levels in seminal plasma of patients orchiectomized for testicular tumors. Materials and Methods The study included 52 patients: 26 control men and 26 orchiectomized patients for testicular tumor, of which 12 men had seminoma tumor and 14 men non-seminoma tumor. After semen analysis performed according to the WHO guidelines, an aliquot of semen was centrifuged and the seminal plasma was collected. Lipid peroxidation was performed by thiobarbituric acid reactive substances (TBARS) assay and antioxidant profile was assessed by analyzing catalase, glutathione peroxidase (GPx) and superoxide anion (SOD) activities using colorimetric assays with a standard spectrophotometer. Data were tested for normality and compared using one-way ANOVA (p<0.05). Results Seminoma and non-seminoma groups presented lower sperm concentration and morphology when compared to control group (p=0.0001). Both study groups (seminoma and non-seminoma) presented higher TBARS levels when compared to control group (p=0.0000013). No differences were observed for SOD (p=0.646) andGPx (p=0.328). It was not possible to access the enzymatic activity of catalase in any group. Conclusion Patients with testicular tumor present increased semen oxidative stress, but no differences were observed in antioxidant levels, even after orchiectomy. This indicates that most likely an increased generation of oxidative products takes place in these patients.

Fibroma testicular / Testicular fibroma

El fibroma paratesticular es un proceso proliferativo benigno de origen incierto, probablemente inflamatorio reactivo no tumoral. El objetivo del trabajo es presentar un caso de fibroma paratesticular, así como la secuencia diagnóstica y terapéutica adoptada. Se presenta un paciente de 55 años de edad con antecedentes de hipertensión arterial. Acude a la consulta externa de Urología por presentar aumento de volumen del testículo derecho, de un año de evolución, que en los últimos tres meses le había ocasionado molestias leves. Al interrogatorio no se recogieron antecedentes de traumatismos o inflamaciones en ese testículo. En el examen físico presentó, hacia el polo inferior del testículo y cola del epidídimo derechos, una masa de consistencia pétrea, irregular, de 3 a 4 cm de diámetro, fija e indolora. El ultrasonido testicular reportó la presencia de una imagen compleja, hacia polo inferior, heterogénea hipo e hiperecoica calcificada en su interior, que medía 33 x 18 x 34 mm para 11cm³ de volumen, y con ligero hidrocele asociado. El paciente fue sometido a orquiectomia radical derecha, proceder que transcurrió sin complicaciones. El resultado histopatológico fue proliferación fibrosa nodular e hialinizante que afecta la túnica albugínea, fibroma calcificado del testículo derecho. La evolución posoperatoria fue satisfactoria. Aunque el diagnóstico definitivo de fibroma paratesticular es histopatológico, sus características clínicas y ecográficas lo hacen ser uno de los diagnósticos diferenciales a tener en cuenta, con los tumores malignos del testículo(AU)

Paratesticular fibroma is a benign proliferative process of uncertain origin, probably non-tumor reactive inflammatory. The aim of the study is to present a case of paratesticular fibroma, as well as the diagnostic and therapeutic sequence implemented. We present a 55 year old patient with a history of hypertension. This patient visits the Urology outpatient clinic because of an increase in volume of the right testicle, a year of evolution, which in the last three months had caused slight discomfort. No history of trauma or inflammation was recorded in the testicle. On the physical examination he presented, to the lower pole of the testis and tail of the right epididymis, a mass of irregular stony consistency, 3 to 4 cm in diameter, fixed and painless. The testicular ultrasound reported the presence of a complex image, towards the lower pole, heterogeneous hypo and hyperechoic calcified inside, which measured 33 x 18 x 34 mm for 11 cm3 volume, and with associated light hydrocele. The patient underwent right radical orchiectomy with no complications. The histopathological result was nodular and hyalinizing fibrous proliferation affecting the tunica albuginea, calcified fibroma of the right testicle. Postoperative evolution was satisfactory. Although the definitive diagnosis of paratesticular fibroma is histopathological, its clinical and ultrasound characteristics make it one of the differential diagnoses to be considered with malignant tumors of the testis(AU)

Adult granulosa cell tumor of the testis masquerading as hydrocele

Adult testicular granulosa cell tumor is a rare, potentially malignant sex cord-stromal tumor, of which 30 cases have been described to date. We report the case of a 43-year-old male who complained of a left testicular swelling. Scrotal ultrasound showed a cystic lesion, suggestive of hydrocele. However, due to a clinical suspicion of a solid-cystic neoplasm, a high inguinal orchidectomy was performed, which, on pathological examination, was diagnosed as adult granulosa cell tumor. Adult testicular granulosa cell tumors have aggressive behaviour as compared to their ovarian counterparts. They may rarely be predominantly cystic and present as hydrocele. Lymph node and distant metastases have been reported in few cases. Role of MIB-1 labelling index in prognostication is not well defined. Therefore, their recognition and documentation of their behaviour is important from a diagnostic, prognostic and therapeutic point of view.

Mesotelioma bem diferenciado (benigno) de túnica vaginal: relato de um caso e revisão da literatura / Well-differentiated (benign) mesothelioma of the tunica vaginalis: report of a case and literature review

Mesoteliomas são tumores oriundos das células mesoteliais da pleura, peritônio, pericárdio ou túnica vaginal, sendo a exposição prolongada ao asbesto o principal fator de risco. Neoplasias mesoteliais benignas da região paratesticular são raras. Relata-se um caso de Mesotelioma de Túnica Vaginal associado à hidrocele, destacando a utilidade da ecografia na avaliação das massas escrotais (AU)

Mesotheliomas are tumors originating from the mesothelial cells of the pleura, peritoneum, pericardium or tunica vaginalis, with prolonged exposure to asbestos the main risk factor. Benign mesothelial neoplasms of the paratesticular region are rare. Here we report a case of tunica vaginalis mesothelioma associated with hydrocele, highlighting the usefulness of ultrasound in the evaluation of scrotal masses (AU)

Stage IIA and IIB testicular seminoma treated post-orchiectomy with radiation therapy versus other approaches: a population-based analysis of 241 patients

Objectives To evaluate post-orchiectomy utilization of radiation therapy (RT) versus other management approaches in stage IIA and IIB testicular seminoma patients. Materials and Methods Two hundred and forty-one patients with stage IIA and IIB testicular seminoma were identified between 1988 and 2003 using the Surveillance, Epidemiology, and End Results (SEER) database. Results Median follow-up was 10 years. Patients with stage IIA disease underwent RT more frequently than those with stage IIB disease (72% vs. 46%, respectively; P<0.001). There was no significant change in RT utilization for stage IIA or IIB disease between 1988 and 2003 (P = 0.89). Conclusions Between 1988 and 2003, stage IIA patients underwent RT more often than stage IIB patients in the United States. There was no significant change in RT utilization for stage IIA or IIB disease during this time period. Based on reports describing excellent progression-free survival with cisplatin-based chemotherapy, this approach has increased in popularity since 2003 and may eventually become the most popular treatment approach for both stage IIA and IIB testicular seminoma. .

Recurrence of acute myeloid leukemia in cryptorchid testis: case report / Recidiva de leucemia mieloide aguda em testículo criptorquídico: relato de caso

A 23-year-old male with a history of bone marrow transplant for acute myeloid leukemia. He presented a large mass in the right inguinal region 5 years ago. Upon physical examination, right-sided cryptorchidism was observed. The tumor markers alpha-fetoprotein and beta-HCG were within normalcy range and lactate dehydrogenase was raised. Computed tomography of the abdomen and pelvis revealed right testicular mass in contiguity with the inguinal canal to the ipsilateral retroperitoneum, associated with right hydronephrosis. Due to the risk of germ-cell tumor in undescended testicle, the patient underwent radical right orchiectomy. The pathological examination showed recurrence of acute myeloid leukemia in the testis. He was referred to oncology for adjuvant therapy. Our literature review found no similar cases described.

Paciente de 23 anos, masculino, com antecedente de transplante de medula óssea por leucemia mieloide aguda. Há 5 anos, apresentou volumosa massa em região inguinal direita. No exame físico, foi constatada criptorquidia à direita. Os marcadores tumorais alfa-fetoproteína e beta-HCG encontravam-se dentro da normalidade, e a desidrogenase láctica estava aumentada. A tomografia computadorizada de abdomen e pelve revelou massa testicular direita com contiguidade pelo canal inguinal, até o retroperitônio ipsilateral, associada a hidronefrose direita. Devido ao alto risco de neoplasia germinativa em testículo criptorquídico, o paciente foi submetido à orquiectomia radical direita, cujo anatomopatológico revelou recidiva de leucemia mieloide aguda em testículo. Foi encaminhado para oncologia para terapia adjuvante. Nossa revisão não revelou nenhum caso semelhante na literatura.

Metástasis testicular de cáncer renal de células claras: reporte de un caso y revisión de literatura / Testicular Metastasis of clear cell renal cancer: report of a case and review of literature

INTRODUCCIÓN: El carcinoma renal es la tercera neoplasia dentro de los tumores genitourinarios, correspondiendo a un 3 por ciento del total de tumores malignos primarios del adulto a nivel mundial. En Chile tiene una mortalidad de 2-3/100.000 habitantes, presentando un 30 por ciento metástasis al momento del diagnóstico, siendo las metástasis testiculares infrecuentes. CASO CLÍNICO: Hombre de 73 años, con antecedente de varicocele izquierdo sintomático sometido a nefrectomía radical laparoscópica izquierda en Mayo 2011 por tumor renal. Biopsia informa carcinoma de células claras tipo clásico, que invade cápsula renal y teiido adiposo perirrenal con área de carcinoma sarcomatoide. Etapificación: Pt2B NX. En Diciembre 2011 presenta aumento de volumen nodular, pétreo e indoloro en testículo izquierdo. Ecografía y ecodoppler evidencian lesión focal hipoecogénica, sólida. Marcadores tumorales negativos. Tras orquiectomía radical izquierda, biopsia indica metástasis de carcinoma de células claras renal. Tomografía computarizada de tórax abdomen y pelvis informa múltiples nódulos pulmonares de aspecto metastásico, clasificándosele en etapa IV, actualmente con cuidados paliativos DISCUSIÓN: Los metástasis testiculares son infrecuentes encontrándose como hallazgos en autopsias u orquiectomías, presentes simultáneamente con el tumor primario renal o precediendo a su diagnóstico. La mayoría son ipsilaterales izquierdas, asociadas a varicocele, y su baja incidencia podría deberse a su temperatura y localización anatómica distal. CONCLUSIÓN: El caso expuesto ilustra la infrecuente presentación de una metástasis de cáncer renal como masa testicular la cual debiese ser considerada frente a una masa sin antecedente de otro cáncer primario o con marcadores germinales negativos, aunque no ha sido descrita previamente en nuestro medio.

INTRODUCTION: Renal cell carcinoma is the third neoplasia in genitourinary tumors, corresponding to 3 percent of adult primary malignant tumors worldwide. In Chile it has a 2-3/100.000 mortality, 30 percent showing metastasis at diagnosis, testicular metastases being rare. CASE REPORT: 73 year old man with a history of symptomatic varicocele who underwent a left radical nephrectomy for renal tumor in May 2011. Biopsy reports clear cell carcinoma classic type that invades renal capsule and perirenal adipose teiido with sarcomatoid carcinoma area. Staging: Pt2B NX. In December 2011 he presents a painless nodular tumor in the left testicle. Doppler ultrasonography evidences a hypoechoic solid focal lesion. Tumor Markers are negative. After left radical orchiectomy, biopsy shows metastasis of renal clear cell carcinoma. Computed tomography of the chest, abdomen and pelvis reported multiple pulmonary metastatic nodules. He was classified as stage IV and currently recieves palliative care DISCUSSION: testicular metastases are an uncommon finding usually in autopsies or orchiectomy samples, present simultaneously or preceding the primary renal tumor. Most are ipsilateral left and are associated with varicocele. Its low incidence may be due to its anatomical distal location or temperature. CONCLUSION: This case illustrates an uncommon presentation of a metastatic renal cancer. It ought to be considered against a testicular mass with no history of another primary cancer or negative germ cell tumor markers, This uncommon finding has not been previously described in our media.

Linfadenectomía retroperitoneal lumboaórtica laparoscópica por vía extraperitoneal en cáncer testicular no seminoma / Extraperitoneal laparoscopic retroperitoneal lymph node dissection in non-seminomatous testicular cancer

Objective: The aim is to describe the technique of extraperitoneal laparoscopic access for retroperitoneal lymph node dissection in a series of patients with testis cancer stage A. Material and Methods: The extraperitoneal approach was performed in 5 patients with stage A testicular cancer. The technique includes the creation of a totally extraperitoneal space, full exposition of the retroperitoneum and classic retroperito-neal lymph node dissection. We analyzed demographic data, histology, access and surgical complications, estimated blood loss and follow up. Results: The average age was 29.4 years old (22-41). The mean operative time was 144 minutes, with an estimated blood loss of 42.4 ml. There were no surgical complications. The average hospital stay was 33.6 hr, and mean number of lymph nodes was 27.4 (24 -32). In long-term follow up there was no recurrence. Discussion: The extraperitoneal approach is an alternative access for retroperitoneal lymph node dissection in testis cancer patients. It allows avoiding potential intestinal lesions and there is no contraindication in patients with prior abdominal surgery.

Objetivo: Mostrar la experiencia en la técnica de disección lumboaórtica por vía totalmente extra-peritoneal, en un grupo de pacientes con cáncer testicular en estadio A. Material y Métodos: La serie está formada por 5 pacientes, portadores de un tumor testicular no seminoma, en estadio A. En ellos se planteó como alternativa la linfadenectomía retroperitoneal lumboaórtica laparoscópica. La técnica quirúrgica consistió en la formación de un espacio extraperitoneal, con rechazo de peritoneo, exposición del retroperitoneo y disección linfática clásica. Se analizaron los datos demográficos, histología, complicaciones del acceso y la técnica quirúrgica, tiempo operatorio, sangrado estimado y seguimiento a largo plazo. Resultados: El tiempo operatorio medio fue de 144 min, con un sangrado medio estimado en 42,5 ml (20-150 ml). No hubo complicaciones intra ni postoperatorias. El tiempo medio de hospitalización fue de 33,6 h. El número medio de nodos linfáticos resecados fue de 27,4 (24 a 32). Con un promedio de seguimiento de 134 meses, no ha habido recurrencia retroperitoneal ni diseminación a distancia. Discusión: La vía extraperitoneal es una alternativa de acceso para la disección linfática retroperitoneal en pacientes con cáncer testicular. Permite evitar potenciales lesiones intestinales y es factible de realizar en pacientes con cirugía abdominal previa.
