Symptomatic occlusion of the inferior vena cava and bilateral iliac veins due to malignant seminoma: Percutaneous recanalization, thrombectomy, and stenting to restore patency

Testicular seminoma is rarely associated with occlusive venous thrombosis. Several investigators describe percutaneous guidewire recanalization for iliofemoral vein thrombosis; however, this technique is ill-documented for occlusion of the inferior vena cava, and even less information is available on managing pervasive iliocaval obstruction. Furthermore, there is limited data on percutaneous mechanical thrombectomy for malignancy-induced venous thrombosis. We present a case of symptomatic chronic occlusion of the inferior vena cava and iliac veins following remission for metastatic seminoma, with percutaneous intervention necessitating a unique combination of sharp wire recanalization, mechanical thrombectomy, and stenting to restore iliocaval patency.

[Paratesticular rhabdomyosarcoma: about a case and literature review]

Nous rapportons une observation d´un rhabdomyosarcome embryonnaire paratesticulaire chez un adulte jeune et soulignons le caractère inhabituel de cette forme histologique dans cette tranche d´âge, l´évolution rapide de la lésion ainsi que les difficultés de prise en charge de ce type de tumeurs dans notre contexte.

[Retroperitoneal lymph node assessment in pediatric paratesticular rhabdomyosarcoma]

Paratesticular Rhabdomyosarcoma accounts for 7 to 11% of pediatric rhabdomyosarcomas. Children older than 10 years have a worse event-free survival (69 to 80% vs. 87 to 92%) than children younger than 10 years. In this location, the relapses are essentially in the retroperitoneal lymph nodes and are often fatal. In European protocols, the assessment of the retroperitoneal lymph nodes at diagnosis is made by imaging whereas it is performed by retroperitoneal lymph node dissection in the American protocols. This method has been proved to improve event-free survival in the group of patient older than 10 years with a tumour bigger than 5cm. In the next European protocol, when nodes will be enlarged a surgical biopsy will be performed, this will be irrespective of age or size, and when no nodes will be enlarged in patients older than 10 years, retroperitoneal lymph node assessment will be performed. Other techniques of lymph nodes assessment will be tested like sentinel node biopsies or PET-scan.

Multidisciplinary management of testicular cancer complicated by thrombosis of the inferior vena cava: a case report

INTRODUCTION

Testicular cancer is a rare disease, most commonly seen in young adults. It represents 1% of solid cancers in men. Inferior vena cava (IVC) thrombosis remains a rare complication of testicular cancer and is often associated with a high risk of pulmonary embolism (PE).

CASE REPORT

The authors report a case of a 26-year-old man presenting with advanced testicular cancer, left-sided retroperitoneal metastasis and parietal infiltration of the IVC complicated with thrombosis of the left iliac vein and the IVC, both responsible for PE.

DISCUSSION

A multidisciplinary management which included curative excision of the lesions, placement of a temporary IVC filter and adjuvant chemotherapy permitted an optimal approach. No complications occurred and the post-operative healing was uneventful. No recurrences were observed on the long-term follow-up.

CONCLUSIONS

IVC Thrombosis is a rare complication that should be taken into consideration when diagnosing testicular cancer. Prompt diagnosis is crucial to minimize the risk of PE which can be life-threatening.

Tuberculous Orchitis Following Intravesical Bacille Calmette-Guérin (BCG) Therapy

Intravesical therapy with Bacillus Calmette-Guérin (BCG) is a common and effective therapy for bladder carcinoma in situ. The risks associated with intravesical BCG therapy are significant and rare. Accurate diagnosis and prompt initiation of management significantly reduce the morbidity associated with these risks. Here, we discuss a case of BCG orchitis, a rare but treatable complication of intravesical BCG therapy. We present the case of a 55-year-old Puerto Rican incarcerated male who was diagnosed with high-grade Stage T1 urothelial carcinoma after presenting with hematuria, treated with transurethral resection of bladder tumor (TURBT), mitomycin, and intravesical BCG. He presented with left testicular pain and swelling after a failed course of ciprofloxacin with ultrasound findings characteristic of BCG orchitis. The patient received a combination therapy of levofloxacin, rifampin, isoniazid, and ethambutol, which resulted in symptom resolution. Combination therapy was initiated in this patient based on a high index of clinical suspicion, and in the absence of positive cultures. Competing diagnoses were considered and excluded based on the history, imaging findings, and observed response to therapy. As this is an uncommon diagnosis, and as routine infectious workup is often inconclusive, we emphasize that early anti-tuberculous treatment should be considered given a high degree of clinical suspicion based on history and patient presentation.

Dissecting the Evolving Risk of Relapse over Time in Surveillance for Testicular Cancer

Testicular cancer is the most common malignancy in young men, and the incidence is increasing in most countries worldwide. The vast majority of patients present with clinical stage I disease, and surveillance is being increasingly adopted as the preferred management strategy. At the time of diagnosis, patients on surveillance are often counselled about their risk of relapse based on risk factors present at diagnosis, but this risk estimate becomes less informative in patients that have survived a period of time without experiencing relapse. Conditional survival estimates, on the other hand, provide information on a patient's evolving risk of relapse over time. In this review, we describe the concept of conditional survival and its applications for surveillance of clinical stage I seminoma and nonseminoma germ cell tumours. These estimates can be used to tailor surveillance protocols based on future risk of relapse within risk subgroups of seminoma and nonseminoma, which may reduce the burden of follow-up for some patients, physicians, and the health care system. Furthermore, conditional survival estimates provide patients with a meaningful, evolving risk estimate and may be helpful to reassure patients and reduce potential anxiety of being on surveillance.

[Germ cell tumor in adolescents and young adults]

Management of extracranial germ cell tumors (TG) is emblematic of the adolescents and young adults' problematic. Beyond persisting differences in care between adult and pediatric oncologists, it emphasizes the need for effective collaboration between both teams. If the therapy is primarily guided today by adult standards, pediatricians bring expertise in long-term follow-up, justified by the increasing description of late side effects in this young population, with highly curable disease since cisplatin's emergence.

"Hockey Stick" may Strike Back: Hepatocellular Carcinoma on Noncirrhotic Liver as a Late Toxicity of Lombo-Aortic Radiotherapy for Seminoma. A Review Triggered by an Unusual Case

Most patients with testicular seminoma have been treated with a curative intent for decades. Second cancers after radiotherapy for testicular seminoma before 1990 are a growing issue, and are related to previous generation of dose planning and delineating strategies. Among those cancers, hepatocellular carcinoma is an extremely rare occurrence, especially when affecting patients with healthy, noncirrhotic liver. Here, we describe such a case in a patient of our institution, and subsequently review the relevant literature and large epidemiologic studies. Understanding those late and serious toxicity features may help cancer care teams to screen and treat those patients appropriately.

Late recurrent testicular seminoma: histological evidence is required

INTRODUCTION

Over the past 3 decades, the appropriate management of metastatic germ cell tumours (GCT) has been defined by several phase III trials. Many follow-up recommendations have been published based on expert consensus. However, common clinical scenarios can still be vexing for clinicians who are less experienced at managing patients with testicular cancer.

CASE REPORT

We highlight the arduous diagnostic work-up of a suspected late relapsing metastatic GCT in a patient suffering from fatigue, weight loss and prominent retroperitoneal lymph nodes, 4 years after first-line chemotherapy for metastatic seminoma. The various explorations finally led to the diagnosis of Whipple's disease.

CONCLUSION

This unusual clinical case strongly highlights the need to perform an exhaustive evaluation, with a biopsy, if a late recurrent GCT is suspected to avoid pointless and potentially harmful treatment.

[Management of testicular teratoma: update by the Oncology Committee of the French Urology Association, section of External Genital Organs (CCAFU-OGE)]

INTRODUCTION

The objective of this article was to focus on the pathological, clinical and therapeutic aspects of the different forms of testicular teratoma in adults.

MATERIAL AND METHODS

The multidisciplinary working group has conducted a literature search on Pubmed with keywords: adult teratoma; malignant transformation; growing teratoma; chemotherapy; surgery with focus on the different forms of adult testicular teratoma.

RESULTS

Teratomas of the adults are malignant and subdivided into localized and metastatic forms that may be distinguished under exclusive teratoma form, growing teratoma or teratoma with malignant transformation. The management is based on an enlarged surgical excision (testis and metastasis) with, in metastatic forms, a chemotherapy adjusted with histology. Extended follow-up beyond 10 years is necessary because of the risk of late relapse.

CONCLUSIONS

Testicular teratoma is a rare tumor, which is considered malignant with a potential of metastasis. The treatment is based mainly on surgical management.
