[A case of retroperitoneal Castleman's disease associated with bladder tumor and a review of 59 cases in Japan].

We present a case of retroperitoneal Castleman's disease associated with bladder tumor. The patient was a 62-year-old man, who underwent partial cystectomy under a diagnosis of bladder tumor in 1989. Subsequently, recurrent bladder tumor was detected and he consulted the outpatient clinic at our University Hospital in November, 1990, at which time computerized tomography (CT) revealed a retroperitoneal tumor. From February, 1991 four courses of combined chemotherapy (methotrexate, vinblastine, pirarubicin, cisplatin) were administered for the tumor. The tumor reduction rate after the chemotherapy was 60% on CT, and retroperitoneal lymph node dissection and left nephroureterectomy were performed in July, 1991. Histological examination revealed Castleman's disease, hyaline-vascular type. Fifty-nine reported cases of retroperitoneal Castleman's disease in Japan are reviewed.

Castleman Disease

Chylous ascites following retroperitoneal lymphadenectomy.

A case of postoperative chylous ascites accumulation after retroperitoneal lymph node dissection is reviewed. Although uncommon, this complication is distressing and because of the close proximity of the cisterna chyli to the renal pedicles it may be encountered with any retroperitoneal procedures involving this area. Avoidance of the complication by specific identification and ligation of these structures appears to be the best treatment. Several forms of operative and non-operative therapy have been noted and survival rates in the iatrogenic form of chylous ascites appear to be good based on a limited series of cases.

Advances in the management of non-seminomatous germinal tumours of the testis.

Experience in the management of 146 consecutive patients with non-seminomatous tumours of the testis has led to a plan of management based on retroperitoneal lymph node dissection as the primary treatment modality, with use of adjuvant therapy dependent on pathological findings. Chemotherapy has proved to be the most important adjuvant with postoperative radiation therapy reserved only for patients with extensive retroperitoneal metastatic disease. 3-year crude survival for patients with all stages of disease was 78% and in those in whom the disease was confined to below the diaphragm the survival rate was 85%.

Is postchemotherapy retroperitoneal surgery necessary in patients with nonseminomatous testicular cancer and minimal residual tumor masses?

PURPOSE: At least one third of the patients with metastatic testicular cancer are rendered tumor-free by cisplatin-based chemotherapy. One may question, therefore, the routine use of postchemotherapy retroperitoneal lymph node dissection (RLND), especially if the residual masses are less than 20 mm in diameter. To define the role of such surgery, we analyzed the postchemotherapy histology in testicular cancer patients with minimal residual disease. PATIENTS AND METHODS: Seventy-eight patients with advanced nonseminomatous testicular cancer underwent RLND after three to four cycles of cisplatin- or carboplatin-based chemotherapy. In all patients, the largest diameter of the residual retroperitoneal mass was less than 20 mm. RESULTS: Complete fibrosis/necrosis was found in 51 patients, mature teratoma in 22, and vital malignant germ cell tumor in five. In two of the latter five patients, alphafetoprotein (AFP) had increased immediately before RLND. In the 76 patients with normal pre-RLND tumor markers, the presence of undifferentiated malignant teratoma (MTU) in the primary tumor and normal prechemotherapy tumor markers were independent parameters predicting complete fibrosis/necrosis, which was demonstrated in all 15 patients with these two pretreatment parameters. CONCLUSIONS: Postchemotherapy RLND can be omitted in patients with MTU in the primary tumor who have normal AFP/human chorionic gonadotropin (AFP/HCG) before chemotherapy and whose residual retroperitoneal mass is less than 20 mm in diameter. If the pre-RLND tumor markers are normal, RLND should be performed in all other patients with small residual masses, even in the presence of a normal computed tomography (CT) and particularly if regular follow-up of the patients is not guaranteed.

Improved management of nonseminomatous testis tumors.

Two contributions to the management of nonseminomatous germinal cell (NSGC) tumors of the testis are reviewed. First, a midline technique of extended retroperitoneal lymph node dissection (RPLND) has been developed allowing good access to both renal suprahilar zones as well as the traditional hilar and infrahilar areas. This has been employed at Indiana University Medical Center for staging patients with embryonal carcinoma or teratocarcinoma of the testis who had negative preoperative chest tomography. Of 58 consecutive patients from 1965-1975, 30 were Stage A and 28 Stage B. Thirty of 30 Stage A patients survived (100%) and 24 of 28 (86%) operated Stage B patients survived, for an overall survival of 54/58 (93%). The second contribution relates to development of a new combination chemotherapy protocol for Stage C disease. Preoperative Stage C lesions are treated with Platinum, Velban and Bleomycin (PVB). Those who achieve clearance of pulmonary tumors but who have anatomic or serologic evidence of persistent retroperitoneal tumor after PVB chemotherapy are later treated with RPLND. Six of 12 such patients have been rendered tumor free and now enjoy complete remission. Furthermore, 33 of 50 (66%) patients with disseminated Stage C disease achieved initial complete remission using this drug combination. Twenty-six remain in continuous complete remission with no evidence of disease from 2 to 4 years. Seven are alive, in partial remission, and 17 are dead. Improving chemotherapy opens alternative methods of managing advanced testis cancer.

[Successful management of choriocarcinoma of the testis with brain metastasis: a case report].

A 32-year-old Japanese male consulted a clinic complaining of gynecomastia. Right painless scrotal swelling was also detected. Right high orchiectomy was performed, then the surgical specimen was histopathologically confirmed as choriocarcinoma and mature teratoma. The imaging revealed cerebral, pulmonary, retroperitoneal metastases. After 3 courses of combination chemotherapy with cisplatin, etoposide and peplomycin (PEP therapy), the brain metastasis completely disappeared and the serum titer of the tumor markers such as beta-HCG became normal. The regression rates of lung and retroperitoneal metastases were 68% and 27%, respectively. Therefore, retroperitoneal lymph node dissection was performed. After the 5th course of PEP therapy, lung metastases disappeared completely. Until the present, no evidence of disease has persisted. The PEP therapy, which is a salvage therapy for refractory testicular cancer, was performed as first-line chemotherapy in this case. It was an excellent modality against choriocarcinoma, along with the surgical treatment.

Chemotherapy in stage II testicular tumours: preliminary communication.

Twenty-six patients with stage II testicular teratomas (metastatic spread to the retroperitoneal lymph nodes only) were treated after retroperitoneal lymph node dissection (RLD) by cytostatic chemotherapy with or without radiotherapy. So far, eight patients (30.5%) have recurrent disease, with a median interval of 21 months from time of diagnosis to relapse. The 3-year survival rate for the total group (relapse-free and relapsed patients) was 85.7%. The median survival is not yet reached after 36 months. The own results and reports of the literature show an advantage of early cytostatic treatment over its institution in widespread disease only. It remains to be clarified whether chemotherapy in stage II disease prevents or only delays metastatic spread.

Spermatocytic seminoma.

A case is reported of a forty-four-year-old man with spermatocytic seminoma with no evidence of metastasis for twelve years. This patient is the second to have undergone retroperitoneal lymph node dissection and the third to have histopathologic examination of these lymph nodes. Review of 52 cases of spermatocytic seminoma disclosed 70 per cent of patients were over fifty years of age; none developed in a cryptorchid testis, none occurred in associated with teratoma, and there was no histopathologic evidence of metastasis. Whether or not radiation therapy is necessary is questionalbe. Prognosis appears to be good if not better than in classic seminoma. Available data indicate that spermatocytic and classic seminoma are two distinct neoplasms with different histogenesis and pathologic, clinical, and biologic features.

Sertoli cell tumor of testis.

A case is reported of a patient with Sertoli cell tumor of the testis, the second known to have had a lymphangiogram and the third with histopathologic examination of retroperitoneal lymph nodes. Lymphangiography was performed because of extension of the tumor through the tunica albuginea into the adjacent adherent scrotum at the site of previous testicular biopsy. The lymphangiogram proved to be falsely positive following retroperitoneal lymph node dissection. The patient has remained clinically free of tumor for eight years.

Pilot study to evaluate impact of a policy of adjuvant chemotherapy for high risk stage 1 malignant teratoma on overall relapse rate of stage 1 cancer patients.

A total of 41 patients with stage 1 malignant teratoma of the testis treated from January 1986 to June 1990 was entered into a pilot study of 2 courses of adjuvant cisplatin-based combination chemotherapy. Of the patients 22 had a high or intermediate risk of relapse according to the Medical Research Council (United Kingdom) prognostic factor analysis and surveillance was instituted for 19 patients with a low relapse risk. The overall relapse rate in this group of patients (median followup 2 years) was 9.7% (5% in the adjuvant group and 16% in the surveillance group), which was significantly better than the 35% rate in the historical series treated by surveillance from 1980 to 1985 and equaled or was possibly better than that reported from adjuvant retroperitoneal lymph node dissection. Justification for consideration of 1 course of adjuvant treatment for such cases is reviewed, and the need for examination of such an approach in a neoadjuvant setting with either lymph node dissection or surveillance is examined.

Lymphangiography in patients with malignancy in a non-descended testicle.

Lymphangiography was performed on 23 patients with malignancy in non-descended testicles, 14 of whom had seminomatous and 9 non-seminomatous tumors. Lymph node metastases were shown by lymphangiography in 8 patients: 3 in lumbar nodes, 1 in iliac nodes alone and 4 in lumbar and iliac lymph nodes. Microscopic metastases were shown in lumbar nodes at retroperitoneal lymph node dissection in 2 patients when the lymphangiograms were negative. Iliac lymph node metastases are rare in testicular tumors but may be seen in tumors of non-descended testicles, alone or in combination with lumbar metastatic disease. This information is extremely important for the radiologist as well as the clinician in the management of patients.

Primary leiomyosarcoma of the epididymas.

The fourth case of leiomyosarcoma of the epididymis is reported. It is suggested that radical orchiectomy, followed by frequent postoperative examinations, is an adequate method of treatment. Retroperitoneal lymph node dissection does not seem to be indicated.

Lipoplastic lymphadenopathy simulating malignant lymphoma and pelvic lipomatosis: Report of a case and review of the literature.

The second known cases of pelvic lipoplastic lymphadenopathy is presented. Roentgenographic studies including lymphangiography were instrumental in the diagnostic evaluation but a histopathologic diagnosis was essential to exclude a neoplastic process. The etiology and natural history of this disease are indeterminant but seemed to pursue a benign 17-year course in our patient. A retroperitoneal lymph node dissection is not indicated unless encroachment on adjacent pelvic viscera causes mechanical obstruction.

Diagnosis, Differential

Renal cell carcinoma presenting as right atrial tumor with successful removal using cardiopulmonary bypass.

A 58-year-old male presented with signs and symptoms of right sided heart failure. Diagnostic evaluation revealed a right renal cell carcinoma with extension into the vena cava and right atrium. Surgical management included radical right nephrectomy with retroperitoneal lymph node dissection, inferior vena caval resection, and removal of the intra-atrial tumor thrombus using a cardiopulmonary bypass. Two years after surgery the patient is alive and well with no evidence of recurrent disease.

Treatment of testicular tumors.

A total of 145 consecutive primary testicular tumors were treated with radiation therapy at the University of Michigan Hospital from 1955 through 1974. In patients with seminoma, the 5-year survival rate was 98% for Stage I and 88% for Stage II regardless of whether retroperitoneal lymph node dissection was done. The 5-year survival rate for embryonal carcinoma was 63% for Stage I and 66% for Stage II. For teratocarcinoma it was 100% for Stage I and 54% for Stage II. Adjuvant chemotherapy appeared to be beneficial for patients with Stage II teratocarcinoma but made no difference in patients with embryonal carcinoma.

Surveillance after orchidectomy for patients with clinical stage I nonseminomatous testis tumors.

PURPOSE: This study was designed to determine the proportion of patients with clinical stage I nonseminomatous germ cell tumors of the testis (NSGCTT) managed with surveillance after orchidectomy who have more advanced disease and, therefore, require further treatment, the time to progression, the sites of progression, and the efficacy of treatment delayed until progression was recognized. PATIENTS AND METHODS: One hundred five patients were observed prospectively without further treatment after orchidectomy and full clinical staging. Treatment was given immediately upon detection of marker-positive, clinical, or radiologic evidence of disease. RESULTS: Thirty-seven patients (35.2%) have required further therapy for disease progression, occurring from 2 to 21 months after diagnosis. Thirty-six patients have been successfully treated. Overall, 104 patients (99%) remain alive and free of disease at 12 to 121 months after orchidectomy. Progression occurred in the retroperitoneum in 25 of 37 patients who developed further disease on surveillance. The presence of vascular invasion in the primary tumor was predictive of an increased risk of progression. CONCLUSION: Surveillance is a valid alternative to immediate retroperitoneal lymph node dissection in patients with clinical stage I NSGCTT but should be recommended only under the close supervision of physicians experienced in the diagnosis and treatment of testicular cancer.

Postoperative respiratory failure secondary to Pneumocystis carinii pneumonia.

Pneumocystis carinii pneumonia (PCP) occurs frequently in individuals infected with the HIV virus. Malignancy, immunosuppressive drugs, and congenital immune deficiency may be associated with PCP. We describe a patient with stage 1 testicular carcinoma who developed hypoxemic respiratory failure two days after retroperitoneal lymph node dissection. Pneumocystis carinii organisms were demonstrated by catheter lavage samples and confirmed on bronchoalveolar lavage. Testing for HIV antibody by ELISA and the Western blot test were negative; HIV viral culture and polymerase chain reaction were also negative. Pneumocystis carinii pneumonia is unusual in localized surgically cured malignancies without obvious immunodeficiency and, to our knowledge, has not been described as a cause of postoperative respiratory failure.

Treatment of anejaculation with electroejaculation.

Male infertility caused by anejaculation is common after spinal cord injury (SCI) and following retroperitoneal lymph node dissection (RPLND) for testicular cancer. Other conditions sometimes associated with neurogenic ejaculation loss are diabetes mellitus, multiple sclerosis, extensive pelvic surgery and adult myelodysplasia. Primary absence of ejaculation also has been described. Few treatment options exist for these patients, if they wish to father a child. With electroejaculation (EEJ), or the low-current stimulation of the ejaculatory organs via a rectal probe, emission of semen can be initiated in these men. In non-SCI-patients EEJ requires general anaesthesia. The collected semen is washed and the motile sperm fraction isolated before artificial insemination (AI) of the partner. At the University of Michigan 198 men have been treated between 1986 and December 1991. An ejaculate could be obtained from nearly all patients. A major obstacle to success is the severe asthenozoospermia and the poor functional quality of the obtained sperm samples. This can be caused by the EEJ-technique itself, as well as by the long anejaculatory status. A semen sample with at least 10 million progressively motile sperm cells, useful for AI, was obtained in 75% of the SCI men and in 87% of the men following RPLND. In the couples wishing insemination, 49 pregnancies were induced, accounting for an overall pregnancy rate of 35% per couple. Thirty five healthy babies have been born. Only three complications were encountered. At Hannover Medical School only few patients have been stimulated to date. We could obtain an adequate sperm sample for AI from all of them. No complications were seen. As the first couple has just entered the phase of AI with husband sperm, an analysis of these results would be premature. Electroejaculation combined with artificial insemination is an efficient and safe treatment of male infertility due to neurogenic anejaculation.
