RESUMEN

PURPOSE: Testicular cancer survivors (TCS) exposed to chemotherapy have an increased expression of CDKN2A/p16INK4a and a lymphocyte phenotype associated with immunosenescence. We seek to define whether the immunosenescent phenotype is associated with chemotherapy. METHODS: Case-control study of TCS, disease-free ≥3 months and stratified by primary treatment modality into orchiectomy only, chemotherapy, or bone marrow transplant (BMT). Each group was compared with age-matched healthy controls (HC). We measured the relative proportions of lymphocyte subpopulations using flow cytometry, levels of C-reactive protein, and relative expression of CDKN2A/p16INK4a quantified by qPCR. RESULTS: We included 65 patients; 19 were treated with orchiectomy only, 35 received different doses of chemotherapy, and 11 underwent BMT. The chemotherapy and BMT groups had decreased naïve CD4 cells compared to HC. The chemotherapy group showed increased central and effector memory CD4 cells, as well as effector and terminally differentiated CD8 cells, compared to HC. Chemotherapy (chemotherapy 1.84 vs. HC 0.92; p < 0.01) and BMT (BMT 6.96 vs. HC 1.25; p < 0.005) groups had higher expression of CDKN2A/p16INK4a compared to HC. The orchiectomy group showed no significant difference with HC (orchiectomy 1.73 vs. HC 1.01; p = 0.17). CRP levels were higher in all groups when compared with HC; in the orchiectomy group, they were only marginally increased (chemotherapy 0.22 vs. HC 0.06; p < 0.01; BMT 0.26 vs. HC 0.06; p < 0.01; orchiectomy 0.09 vs. HC 0.07; p < 0.01). CONCLUSIONS: Among TCS, only patients exposed to cytotoxic agents developed an immunosenescent phenotype. This finding supports the attribution of this alteration to the cytotoxic treatment.

RESUMEN

Testicular germ cell tumors are the most common tumors in adolescent and young men. They are curable malignancies that should be treated with curative intent, minimizing acute and long-term side effects. Inguinal orchiectomy is the main diagnostic procedure, and is also curative for most localized tumors, while patients with unfavorable risk factors for recurrence, or those who are unable or unwilling to undergo close follow-up, may require adjuvant treatment. Patients with persistent markers after orchiectomy or advanced disease at diagnosis should be staged and classified according to the IGCCCG prognostic classification. BEP is the most recommended chemotherapy, but other schedules such as EP or VIP may be used to avoid bleomycin in some patients. Efforts should be made to avoid unnecessary delays and dose reductions wherever possible. Insufficient marker decline after each cycle is associated with poor prognosis. Management of residual masses after chemotherapy differs between patients with seminoma and non-seminoma tumors. Patients at high risk of relapse, those with refractory tumors, or those who relapse after chemotherapy should be managed by multidisciplinary teams in experienced centers. Salvage treatment for these patients includes conventional-dose chemotherapy (TIP) and/or high-dose chemotherapy, although the best regimen and strategy for each subgroup of patients is not yet well established. In late recurrences, early complete surgical resection should be performed when feasible. Given the high cure rate of TGCT, oncologists should work with patients to prevent and identify potential long-term side effects of the treatment. The above recommendations also apply to extragonadal retroperitoneal and mediastinal tumors.

RESUMEN

BACKGROUND: High-dose chemotherapy followed by stem cell transplant (HDCT) is potentially curative for patients with refractory germ cell tumors (rGCT). There is scarce real-world data supporting its implementation in low- and middle-income countries. We described the experience of our tertiary cancer center in Sao Paulo, Brazil. METHODS: We identified male patients ≥18 years-old with rGCT referred to HDCT after board discussion. Clinical data, including delays in HDCT protocol, were extracted from medical records, and survival outcomes were estimated using the Kaplan-Meier method. The log-rank test and Cox proportional hazard were used to determine effects on overall survival (OS). RESULTS: From January 2013 to January 2023, 34 patients were referred and considered eligible to receive 2 cycles of HDCT. Most patients had primary testicular tumors (82%), nonseminomatous histology (88%), and poor International Germ Cell Collaborative Group (IGCCCG) (79%). Twenty-three patients received HDCT (1 cycle, n = 8; 2 cycles, n = 15). Main reasons for not receiving any HDCT were death due to progressive disease (n = 1), performance deterioration (n = 7), and failure of stem cell mobilization (n = 3). OS at 2 years was 36.7% for the eligible population, 56.1% for patients who underwent at least 1 HDCT, and 77.1% for those who had ≥2 cycles. The 2-year OS rate for patients not given HDCT was 0%. All patients had delays in protocol, and poor-risk patients had longer intervals from referral to protocol initiation (0.7 vs. 1.8 month, P < .01). CONCLUSION: Outcomes of patients who received ≥1 HDCT were encouraging; however, only 15 from 34 eligible patients were able to receive the planned 2 cycles of HDCT. Further strategies to minimize treatment delays in low- and middle-income countries are needed.

RESUMEN

Undescended testis (UDT) is defined as failure of a testis to descend into the scrotum and it is a common reason for consultation in pediatric urology. As extensively discussed in "The undescended testis in children and adolescents: part 1", the failure of a testis to descend alters testicular germ-cells development, increasing the risk of infertility and testicular cancer in adulthood. Here, we present the second part of our review and analysis of this topic with the aim to propose an updated and well-informed approach to UDT together with a treatment flow chart that may be useful to guide pediatric surgeons and urologists in the care of these patients. The main goal of the management of patients with UDT is to diminish the risk of infertility and tumor development and is based on the clinical findings at the time of diagnosis.

RESUMEN

BACKGROUND: Genitourinary tract tumors in children are less common than in adults. Most of these tumors have different genetic backgrounds, clinical presentation, and oncologic behavior than their adult counterpart. As a result of low prevalence in children, some of the treatment approaches and recommendations are based on treatment experience in adult patients. However, thanks to scientific and technological development, survival rates have risen considerably. OBJECTIVE: This paper presents a review of the principal features of the tumors involving the genitourinary tract in children and an update in genetic background, diagnosis, and treatment. METHODS: A narrative review was performed on published literature about genitourinary tract tumors in pediatric patients. Papers presented in English and Spanish literature were reviewed. PubMed, Science Direct, and SciELO databases were used to collect information and present this article. RESULTS: Kidney tumors are the most common type of genitourinary tumors in children. Among those, Wilms tumor represents the majority of cases and shows the successful work of clinical trial groups studying this tumor type. Other tumors involving the genitourinary tract in children include Rhabdomyosarcoma, Transitional cell carcinoma, Testicular, and Adrenal tumors. CONCLUSION: Genitourinary tract tumors in children represent significant morbidity and economic burden, so awareness in early diagnosis represents improvement in treatment, clinical, and oncological outcomes.

RESUMEN

ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), comprising both seminoma and non-seminoma tumors, are considered the main subtypes of testicular neoplasms. TGCT are characterized by being a solid tumor that mostly affects young men aged between 15 and 40 years old. While TGCT subtypes may have an invasive potential, seminoma subtype does not affect other cells rather than germ cells, while non-seminomas have more invasive properties and can achieve somatic cells; thus, having a more aggressive nature. This research intends to review the literature regarding information about sperm parameters, correlating the data found in those studies to the subfertility and infertility of patients with TCGTs. Furthermore, it will also correlate the data to the non-seminoma and seminoma histological subtypes from pre- and post-cancer therapy. PubMed databases were used. Searched keywords included: seminoma AND non-seminoma; male infertility; germ cell tumor; chemotherapy AND radiotherapy. Only articles published in English were considered. Current studies demonstrate that both TGCT subtypes promote deleterious effects on semen quality resulting in decreased sperm concentration, declined sperm total motility and an increase in the morphology alterations. However, findings suggest that the non-seminoma subtype effects are more pronounced and deleterious. More studies will be necessary to clarify the behavior of seminoma and non-seminoma tumors implicating the reproductive health of male patients.

RESUMEN

The case An 18-year-old male presented with a one-month history of a nonpainful right testicular enlargement. He had no family history of neoplasia, nor any relevant past medical history. The physical examination was only remarkable for an enlarged right testicle. A testicular ultrasound revealed a 2.5-cm tumor, and serum tumor markers revealed an elevated ß-human chorionic gonadotropin (ß-HCG), 22 mUI/L (normal, < 0.06 mUI/L); elevated alpha-fetoprotein (AFP), 329 ng/mL (normal, 0-9 ng/mL); and normal lactate dehydrogenase (LDH), 135 /L (normal, 179 U/L). A right radical inguinal orchiectomy was performed. Pathological examination revealed a 2.4 cm by 2 cm embryonal carcinoma with tumor invasion into the tunica albuginea. Postsurgical tumor markers obtained 3 weeks after orchiectomy were ß-hCG, 100.5 mUI/L (normal, < 0.06 mUI/L); AFP, 1075 ng/mL (normal, 0-9 ng/mL); and LDH, 180 U/L (normal, 179 U/L). A chest, abdomen, and pelvis CT scan showed a 2.7-cm retroperitoneal lymph node enlargement, without visceral metastasis. Given the presence of node-positive disease with S2 serum markers, the diagnosis of a stage IIIB intermediate risk nonseminomatous germ cell tumor (NSGCT) was determined, and the patient underwent sperm banking. The patient was started on chemotherapy with 4 cycles of BEP (bleomycin, etoposide, and cisplatin), with a favorable tumor marker decline according to the Gustave-Roussy nomogram. After completion of the fourth chemotherapy cycle, serum tumor markers were negative, and 8 weeks after chemotherapy, the follow-up CT showed a 1.6-cm residual retroperitoneal lymph node conglomerate.

RESUMEN

ABSTRACT Purpose: To evaluate whether components of Testicular Dysgenesis Syndrome (TDS) affect testicular germ cell tumor (TGCT) prognosis and oncological outcomes. According to the hypothesis called TDS; undescended testis, hypospadias, testicular cancer and spermatogenic disorders share the same risk factors and have a combined fetal origin. Materials and Methods: We retrospectively evaluated the stages and oncological outcomes of 69 patients who underwent radical orchiectomy between January 2010 and December 2014 due to TGCT in our department. The presence of undescended testis, hypospadias and semen parameters disorders were recorded according to anamnesis of patients. Results: Among 69 patients with TGCT, only 16 (23.1%) had TDS. Significantly higher rate of TDS (36.1% vs. 9.1%) was observed at the advanced stages of TGCT(p=0.008). In the TDS group, the rates of local recurrence (50% vs. 11.3%, p<0.001), distant metastasis (93.6% vs. 3.8%, p<0.001) and cancer-spesific mortality (87.5% vs. 3.8%, p<0.001) were found significantly higher than those without TDS. The predicted time for recurrence-free survival (13.70±5.13 vs. 100.96±2.83 months, p<0.001) metastasis-free survival (13.12±4.21 vs. 102.79±2.21 months, p <0.001) and cancer-specific survival (13.68±5.38 vs. 102.80±2.19 months, p<0.001) were also statistically lower in this group. Conclusions: According to our preliminary results, there is an apparent relationship between TDS and tumor prognosis. Even if the components of TDS alone did not contain poor prognostic features for TGCT, the presence of TDS was found as the most important independent predictive factor for oncological outcomes in both seminomas and nonseminomas as well as all patients with TGCT.

RESUMEN

Resumen El tumor desmoplásico de célula redonda y pequeña (TDCRP) es una patología neoplásica maligna agresiva y poco común. Afecta predominantemente a hombres entre la segunda y tercera década de la vida. Los pacientes que la padecen tienen un pronóstico pobre, con una supervivencia global a 5 años de hasta el 30%. Por lo general se presenta como una masa en la cavidad abdominal, frecuentemente multifocal. Para su tratamiento se recomienda un enfoque multimodal con cirugía, quimioterapia y radioterapia. Poco más de 20 casos de TDCRP a nivel testicular/paratesticular se han reportado en la literatura. A continuación, se presenta un caso ilustrativo en esta localización, se discute el caso y se realiza revisión de la literatura.


Abstract Desmoplastic small round cell tumor (DSRCT) is an aggressive and rare malignant neoplasm. It mainly affects young men in their twenties and thirties. Patients with it have a poor prognosis, with a 5-year survival rate of up to 30%. It generally presents as a mass in the abdominal cavity, often multifocal. A multimodal approach is recommended for its treatment, with surgery, chemotherapy, and radiotherapy. Just over 20 cases of testicular/paratesticular DSRCT have been reported in the literature. Below, we present an illustrative case in this location, we discuss the case and review the literature.

RESUMEN

ABSTRACT Introduction: There is little information on how to prioritize testis cancer (TC) patients' care during COVID-19 pandemic in order to relieve its pressure on the health care systems. Objective: To describe the recommendations for diagnosis, treatment and follow-up of patients with TC amidst COVID- 19 pandemic. Material and Methods: Pubmed search and review of the main urological association guidelines on TC. Results: The biology of TC requires immediate care of patients during diagnosis, initial surgical therapy and management of recurrent disease. Active surveillance is the first choice of management and should be offered to all compliant clinical stage I TC patients provided they understand the need to self-isolate. Active surveillance may also help decrease the demand for intensive care unit beds, ventilators, personal protective equipment, and other critical hospital and human resources by minimizing surgeries without compromising patient outcomes. Complications of therapy and symptomatic patients represent medical emergencies and should be treated immediately. Telemedicine may be useful during follow-up periods. Conclusions: Most stages of testis cancer require urgent care; however, all recommendations must be adapted to local health care priorities considering that most of these patients are at low risk of severe COVID-19 infection.

RESUMEN

Bilateral testicular germ cell tumors (BTGCT) occur in 1 to 4% of patients with testicular cancer and of these, 10-15% are synchronous. Overall, BTGCT represents less than 0.5% of all new cases of testicular cancer. There are few reports in the literature of synchronous BTGCT with different histology. We present the case of a 30-year-old man who presented to our genitourinary tumor unit with a bilateral increase of testicular volume. After initial assessment, a testicular ultrasound showed the presence of solid tumors in both testes. Staging studies were negative for metastatic disease. The patient was referred to the fertility clinic for sperm banking and later underwent a bilateral radical orchiectomy. The histopathology evaluation revealed a 5.5 cm right-sided mixed germ cell tumor and a 1.5 cm left-sided testicular seminoma. Because patient's poor compliance for surveillance was identified as a risk factor for relapse and poor outcome, adjuvant chemotherapy was favored. The patient underwent one cycle of bleomycin, etoposide and cisplatin (BEP). After four years of follow up, the patient shows no evidence of relapse, either clinically or radiologically. In men unlikely to carry out successful surveillance; active treatment is the preferred option for preventing disease recurrence, even in patients with no risk factors. The physician must consider all available therapeutic measures in this scenario to achieve the best possible therapeutic result.

RESUMEN

Abstract Most patients with testicular germ cell tumor present with a painless scrotal mass. We report a 19-year-old patient who presented with neurological complains. Rapid clinical progression to coma was noted during the staging work up. A diagnosis of testicular mixed germ cell tumor with multiorgan metastasis (lymph node, lung, liver and brain) was made. Patients with brain metastasis should receive chemotherapy alone or combined with surgery or radiotherapy. Because the clinical symptoms deteriorated quickly, surgery was used upfront followed by chemotherapy and radiotherapy for the brain tumor. After the first stage of treatment, the clinical symptoms, tumor markers and imaging findings were improved. The residual brain tumor was eliminated by chemotherapy, and only sparse degenerated tumor cells were noted in the brain tissue. Longer follow up is required to assess the impact of our treatment strategy.

Patients with brain metastasis should receive chemotherapy alone or combined with surgery or radiotherapy. Because the clinical symptoms deteriorated quickly, surgery was used upfront followed by chemotherapy and radiotherapy for the brain tumor. After the first stage of treatment, the clinical symptoms, tumor markers and imaging findings were improved. The residual brain tumor was eliminated by chemotherapy, and only sparse degenerated tumor cells were noted in the brain tissue. Longer follow up is required to assess the impact of our treatment strategy.

RESUMEN

ABSTRACT Purpose: The current first - line treatment for non - seminomatous germ cell tumor (NSGCT) consists of four cycles of cisplatin, etoposide, and bleomycin (BEP), which results in 5 - year overall survival < 60% in patients with poor - risk features. Autologous hematopoietic stem cell transplantation (auto - HSCT) as a method for overcoming high toxicity after high dose chemotherapy (HDC) has been explored in different solid tumors, but has remained standard practice only for NSGCT. Our objective was to describe outcomes of patients with poor - risk NSGCT who underwent first - line autologous HSCT in a tertiary center in Mexico. Patients and Methods: Twenty nine consecutive patients with NSGCT who received first - line, non - cryopreserved autologous HSCT at the National Institute of Medical Sciences and Nutrition Salvador Zubiran in Mexico City, Mexico, from November 1998 to June 2016, were retrospectively analyzed. Results: The median age at transplantation was 23 (15 - 39) years. Most patients (n = 18, 62%) had testicular primary tumor, and 23 had metastases (79%). Complete response after auto - HSCT was observed in 45%. Non - relapse mortality was 0. Five - year relapse / progression free and overall survival were 67% and 69%, respectively. Conclusions: This small single limited - resource institution study demonstrated that patients with poor - risk NSGCT are curable by first - line HDC plus autologous HSCT and that this procedure is feasible and affordable to perform using non - cryopreserved hematopoietic stem cells.
