Cytoreductive surgery in disseminated non-seminomatous germ cell tumours of testis.

Between 1977 and 1988, 67 patients underwent surgical removal of residual metastatic deposits following an aggressive chemotherapy regimen (cisplatin, vincristine, methotrexate and bleomycin alternating with etoposide, actinomycin D and cyclophosphamide) for disseminated germ cell tumours of the testis (stage IIB or above). Ninety-one surgical procedures were performed. There were 63 (69 per cent) retroperitoneal lymph node dissections, 16 (18 per cent) thoracotomies, three (3 per cent) hepatic resections, three (3 per cent) craniotomies, five (5 per cent) delayed orchidectomies and one anterolateral decompression of the vertebral column. Nine (13 per cent) patients required a repeat retroperitoneal node dissection and one patient needed a repeat thoracotomy to remove recurrent metastatic deposits during the period of follow-up. Multivisceral resections and vascular reconstruction procedures were required in 20 (30 per cent) patients undergoing retroperitoneal node dissection. Fifty-five (82 per cent) patients remain in complete remission with a mean follow-up period of 49.6 months (range 2-121 months). Nine (13 per cent) patients died with metastatic disease between 2 months to 4 years after operation. There were three deaths in the perioperative period (4 per cent). The histology of the resected metastases revealed undifferentiated active tumour in 20 (30 per cent) patients, differentiated mature teratoma in 29 (43 per cent) patients and fibrosis/necrosis in 18 (27 per cent) patients. Twelve (60 per cent) patients with undifferentiated elements and 15 patients (60 per cent) with raised preoperative tumour markers (poor prognostic categories) are in complete remission. Cytoreductive surgery in patients with metastatic germ cell tumours offers the best chance of remission following chemotherapy even in poor prognostic group categories.

[Value of limited dissection of residual retroperitoneal masses after chemotherapy for malignant non-seminoma tumors of the testis. Apropos of 74 cases].

Since asplatin salts have been used in chemotherapy, the efficiency of this treatment has changed the destiny of advanced forms of testicular cancer. The universally recommended treatment of post-chemotherapy residual retroperitoneal tumor masses is radical retroperitoneal lymph node dissection. Results of our 74 limited expresses of these tumor masses confirm that the chosen treatment was appropriate. It guarantees the future and limits genital sequellae in young patients. It is perfectly consistent with the therapeutic history of this model in cancerology: precisely defined indications for the therapeutic means of a pluridisciplinary pool of resources always increases efficiency, reduces the need for invasive treatment, and limits sequellae.

[A case of teratoma of the testis with retroperitoneal lymph nodes involved with malignant teratoma after chemotherapy].

This report describes a case of teratoma with retroperitoneal lymph nodes involved with malignant teratoma (enteric adenocarcinoma) after extensive chemotherapy for the original testicular cancer. A 18-year-old man with a mixed cell tumor (embryonal carcinoma+teratoma+yolk sac tumor) received three courses of VAB-6 chemotherapy for bulky mass following inguinal orchiectomy. He was referred to Tochigi Cancer Center for treatment of a residual mass. He was treated with resection of the mass combined with left nephrectomy due to severe adhesion and pathological diagnosis of the resected lymph node was mature teratoma with a massive necrotic tissue. Two courses of BEP chemotherapy were given to the patient following the surgery. Six months after completion of chemotherapy, a retroperitoneal mass of 1.5 cm in diameter, was detected by CT scan. Standard retroperitoneal lymph node dissection was performed and the pathological diagnosis of the lymph node was teratoma with malignant transformation containing enteric adenocarcinoma. Teratomatous portion of the primary lesion was precisely re-examined and adenocarcinoma, similar histology to the retroperitoneal mass, was identified. He received two courses of EAP chemotherapy (Cis-platin+etoposide+doxorubicin) as an adjuvant chemotherapy following the surgery and he is alive with no evidence of recurrence for 21 months. Presence of non germ cell malignancy after chemotherapy in testicular cancer has been regarded as a rare phenomenon. Flow cytometric DNA analyses of both embryonal carcinoma and teratoma in the primary lesion, mature teratoma and teratoma with malignant transformation of the retroperitoneal lymph node disclosed that these tumors were all aneuploid tumors.(ABSTRACT TRUNCATED AT 250 WORDS)

[A case report of infantile testicular cancer: dissection of paraaortic lymph node involvement indicated by gradual rise in serum alpha-fetoprotein after orchiectomy].

We present a case of a 32-month-old boy with teratoma accompanied by yolk sac carcinoma and embryonal carcinoma of the right testicle. To treat the gradual rise in serum AFP value 3 months postoperatively, he received combined chemotherapy including VCR, CPM and ADM followed by bilateral retroperitoneal lymph node dissection. The preaortic lymph node disclosed, pathologically, yolk sac carcinoma and embryonal carcinoma, which demonstrated neither degeneration nor necrosis despite remarkable decrease in serum AFP value after the chemotherapy. The patient had normal AFP value and no evidence of recurrent disease 36 months after the lymph node dissection. We emphasize the discrepancy between the response of the tumor marker after the chemotherapy and the histologic alteration. Furthermore, the management of infantile testicular cancer is discussed.

Clinical stage I nonseminomatous germ cell tumors of the testis in childhood and adolescence: an analysis of 31 cases.

A 20-year single-institution experience of clinical stage I nonseminomatous germ cell tumors of the testis (NSGCTT) in childhood and adolescents was reviewed in relation to clinical characteristics, treatment modalities, and survival. Thirty-one patients with clinical stage I NSGCTT were seen between 1980 and 2000: 14 children and 17 adolescents. Yolk sac tumors and/or teratomas occurred in the children, whereas mixed histologies, including embryonal carcinoma, were predominant in the adolescents. After orchiectomy, the children were assigned to surveillance and the adolescents to active treatment: 16 underwent retroperitoneal lymph node dissection (RPLND) and 1 had adjuvant cisplatin-based chemotherapy because of a high-risk histology. Three of the 14 children (21.4%) relapsed 3, 7, and 8 months after orchiectomy: all 3 had yolk sac tumors and presented with increased alpha-fetoprotein levels. No patients had retroperitoneal relapse; two recurred locally and one in the lung. All three children were treated with cisplatin-based chemotherapy with or without surgery. Among the 16 adolescents undergoing RPLND, 4 (25%) had nodal metastases. Three of the 12 patients (25%) who had negative nodes at RPLND relapsed in the lung 3, 7, and 8 months after RPLND. All were treated with cisplatin-based chemotherapy with or without surgery. Five-year relapse-free and overall survival rates for the whole series were 80.6% and 100%, respectively. This series enabled the authors to pinpoint several important aspects of stage I NSGCTT in children and adolescents. In particular, almost all the childhood cases had the same yolk sac tumor histology, the children tended to have localized disease, and an increased alpha-fetoprotein level had a very high predictive value, suggesting that follow-up should include AFP measurements. A conservative approach is the best option in children, while adolescent NSGCTT behaves like the adult disease and management must include similar treatment strategies.

Lymph node metastasis of ovarian cancer: a preliminary survey of 74 cases of lymphadenectomy.

Retroperitoneal lymph node dissection was performed in 74 cases of various types of ovarian malignancies. Fifty-three (71.6%) were histologically confirmed as cancer of epithelial origin and 19 (25.7%) as germ cell tumors. The results indicate that lymphatic metastasis is an exceedingly important route of spreading of this group of malignant diseases. The overall incidence of retroperitoneal positive nodes was 56.8% (42/74). In 49 cases undergoing systemic lymphadenectomy 32 were found to have glandular involvement, of which both aortic and pelvic nodes were positive in 17 cases (53.1%), aortic nodes positive but pelvic negative in six (18.8%), and pelvic nodes positive but aortic negative in nine (28.1%). In 32 cases with primary cancer that originated from the left ovary, 17 (53.1%) were found to have positive pelvic nodes, whereas in 19 cases with cancer arising from the right ovary, only one (5.3%) had metastasis of ipsilateral pelvic nodes. The routes of lymphatic spreading and the significance of lymphadenectomy in ovarian cancer are discussed.

The role of thoracotomy in managing postchemotherapy residual thoracic masses in patients with nonseminomatous germ cell tumours.

OBJECTIVE: To evaluate the clinical outcome and identify prognostic variables in patients with nonseminomatous germ cell tumours undergoing postchemotherapy thoracotomy for residual masses, as the role of this procedure is controversial. PATIENTS AND METHODS: Of 385 patients who underwent postchemotherapy retroperitoneal lymph node dissections between 1988 and 1998, 105 also had 130 thoracotomies. The clinical presentation, chemotherapy regimens, marker status, primary tumour histology, pathology of all resected masses, and clinical outcome of these 105 patients were analysed. RESULTS: The overall discordance rate for synchronous thoracic and retroperitoneal masses was 28%; that for asynchronous thoracic and retroperitoneal masses was 57%. Independent prognostic factors for residual thoracic teratoma or cancer were teratoma (mature or immature) in the primary tumour or retroperitoneal teratoma or cancer. Although three of 12 patients with residual thoracic cancer remained with no evidence of disease, residual thoracic cancer is an independent prognostic factor (P < 0.001) against disease-free survival. CONCLUSION: Postchemotherapy thoracotomy yields important prognostic information, and is therapeutic for most patients with teratoma and a subset with residual viable cancer. The prognostic criteria predictive of fibrosis are not sufficiently accurate to omit resection of residual thoracic masses.

Spermatic cord liposarcoma in a young boy.

We report on a spermatic cord liposarcoma arising in a 16-year-old boy. Treatment consisted of radical orchiectomy without retroperitoneal lymph node dissection, and adjuvant radiation and chemotherapy. The patient has survived 14 months without evidence of recurrence. Paratesticular localization of liposarcoma in patients less than 20 years old is rare. The tumor has no particular characteristic. Treatment consists of radical orchiectomy and the role of retroperitoneal lymphadenectomy is controversial.

Early clinical stages of nonseminomatous testis cancer. Evaluation of the primary treatment and follow-up procedures of the SWENOTECA project.

During a 5-year period, 588 consecutive patients with nonseminomatous testicular germ cell cancer were included by 16 hospitals into the Swedish-Norwegian Testicular Cancer Project (SWENOTECA). A total of 370 (63%) had early clinical stages (CS1, CS1Mk+ and CS2A), and 345 (93%) of these patients underwent pathological staging (PS) by retroperitoneal lymph node dissection (RPLND). The overall clinical staging accuracy was 75%, with no significant difference between hospitals with low, medium or high patient accrual rate. Addition of bipedal lymphography did not improve the clinical staging accuracy compared to evaluation of the retroperitoneum by CT alone. Tumor serum markers before and close monitoring of the levels after orchiectomy gave valuable information regarding risk of retroperitoneal metastases. After a median follow-up period of 5 years 30 (13.8%) of 217 patients with PS1 disease relapsed, only 3 of them later than 18 months from the RPLND. Short orchiectomy to RPLND time interval, vascular invasion and absence of teratoma elements in the primary tumour were significant predictors of relapse in PS1 cases according to multivariate analysis. Unilateral RPLND was not associated with higher relapse rate than a bilateral procedure, but significantly reduced the risk of dry ejaculation after RPLND. None out of 122 PS2 patients who received adjuvant cisplatin-based chemotherapy after RPLND relapsed, despite the fact that 37 of them had only undergone a unilateral RPLND. Repeated CT examinations and most routine blood tests except serum alpha foeto protein (AFP), beta subunit of human chorionic gonadotropin (HCG) and lactate dehydrogenase (LD) may safely be omitted in the follow-up period for patients who have been pathologically staged with RPLND, provided that effective adjuvant chemotherapy has been given to the PS2 patients.

Laparoscopic approaches to urologic malignancies.

Urologic laparoscopy has had its greatest impact on patients with genitourinary malignancies. Only pelvic lymph node dissection and the occasional nephrectomy were considered oncologically feasible early in the evolution of laparoscopic urology. Presently, multiple approaches are considered standard at centers of excellence and in the general community. Laparoscopic adrenalectomy and radical nephrectomy have gained overwhelming acceptance. Laparoscopic cytoreductive nephrectomy has been found to be feasible for select patients with metastatic renal cell carcinoma. Minimally invasive nephron-sparing approaches, such as cryoablation, radiofrequency ablation, and laparoscopic partial nephrectomy, continue to generate great interest, but follow-up remains limited. Early data with laparoscopic radical prostatectomy suggest excellent continence rates and equivalent oncologic results based on pathologic surrogates of cure. However, long-term data are still needed, in addition to validated information regarding return of erectile function and quality of life. Other novel therapies, such as laparoscopic radical cystectomy with urinary diversion and laparoscopic retroperitoneal lymph node dissection, hold great promise of benefiting patients with urologic malignancies.

[Retroperitoneal lymph node metastasis in patients with ovarian cancer].

From 1979 to 1987 retroperitoneal lymph node dissection was performed at the Tokyo University Hospital in 41 cases (pelvic lymph node biopsy was done in 4 cases, pelvic lymphadenectomy in 23 cases, pelvic and paraaortic lymphadenectomy up to the renal vessels in 14 cases) of Stage Ia to IV ovarian cancer following cytoreductive surgery. The incidence of retroperitoneal positive nodes was 11.1% (2/18) in Stage I, 50.0% (5/10) in Stage II, 50.0% (5/10) in Stage III and 0% (0/3) in Stage IV (FIGO criteria without considering the pathologic findings of retroperitoneal lymph nodes). The positive rate of lymph node involvement in Stage II and Stage III was significantly higher than that in Stage I. The tumors involving both ovaries were more likely to metastasize to retroperitoneal lymph nodes. Enlargement of tumors and increased ascites were not the risk factors of retroperitoneal lymph node metastasis. These data suggest that the occurrence of retroperitoneal lymphatic spread in ovarian cancer is comparable to that in uterine cancer and increased by involvement of both ovaries and extension to other pelvic tissues.

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.

Electroejaculation following retroperitoneal lymphadenectomy.

Transrectal electroejaculation was performed in 24 men who were anejaculatory from retroperitoneal lymphadenectomy. Of the men 23 had undergone retroperitoneal lymphadenectomy because of testis cancer. Seminal emission was achieved in all patients. In 21 patients greater than 10 x 10(6) progressively motile sperm with normal morphology were obtained. The average sperm count and motilities obtained were 289 x 10(6) and 18%, respectively, for the antegrade fractions, and 2,051 x 10(6) and 13%, respectively, for the retrograde fractions. Of the 3 azoospermic failures 2 had chemotherapy-induced testicular damage and 1 had carcinoma in situ of the remaining testis. A total of 19 couples underwent artificial insemination with electroejaculated sperm. There were 7 pregnancies achieved in 74 insemination cycles (36.8% of the couples conceived for a 9% cycle fecundity). Routine semen parameters could not predict which couples would be successful in achieving pregnancy. There were 2 first trimester spontaneous abortions. Five healthy children have been born. Electroejaculation is an excellent treatment for anejaculation that persists following retroperitoneal lymph node dissection.

Clinical parameters that predict histology of postchemotherapy retroperitoneal lymph node mass in testicular cancer.

BACKGROUND: Since the advent of cisplatin-based chemotherapy, the majority of metastatic testicular cancers can be cured by chemotherapy followed by retroperitoneal lymph node dissection (RPLND). However, postchemotherapy RPLND confers no therapeutic benefit if the residual mass contains no viable cells. Therefore, to determine which parameters predict a patient's likelihood of having only necrosis in the residual mass, we retrospectively analyzed clinical parameters of patients who underwent postchemotherapy RPLND. METHODS: Data from 27 patients with metastatic testicular cancer were analyzed. The histology of the primary tumor was seminoma in 11 cases and non-seminoma in 16 cases. All of the patients with non-seminoma showed a normalization of tumor markers after chemotherapy. Analysis of clinical parameters included data for the initial histology, pretreatment tumor marker levels, postchemotherapy retroperitoneal mass size, and the histology of the dissected RPLNs. RESULTS: Histological examination of dissected RPLNs showed residual tumor in 27% of seminoma patients and 38% of non-seminoma patients. In seminoma patients, no viable cells were found in all six patients with pretreatment lactate dehydrogenase (LDH) levels below 7.5 times the upper limit of normal, or in all five of the patients with postchemotherapy RPLNs less than 2.5 cm. In non-seminoma patients, no viable cells were found in nine of 10 patients with pretreatment alpha-fetoprotein (AFP) levels less than 2700 ng/mL, or in eight of nine patients with residual mass less than 2.5 cm. CONCLUSIONS: Both postchemotherapy RPLN mass size and pretreatment tumor marker levels are possible predictors for necrosis of the residual mass in testicular cancer patients.

Validity of predictions of residual retroperitoneal mass histology in nonseminomatous testicular cancer.

PURPOSE: To validate predictions of the histology (necrosis, mature teratoma, or cancer) of residual retroperitoneal masses in patients treated with chemotherapy for metastatic nonseminomatous testicular germ cell tumor. PATIENTS AND METHODS: We studied 172 testicular cancer patients who underwent resection while tumor markers were normal. Predictive characteristics for the residual histology were registered, including the presence of teratoma elements in the primary tumor, the prechemotherapy level of tumor markers (alpha-fetaprotein [AFP], human chorionic gonadotropin [HCG], lactate dehydrogenase [LDH]), the size of the residual mass, and the percentage of shrinkage in mass diameter. We calculated the predicted probability of necrosis and the ratio of cancer and mature teratoma with previously published logistic regression formulas. RESULTS: The distribution of the residual histology was necrosis in 77 (45%), mature teratoma in 72 (42%), and cancer in 23 (13%). Necrosis could be well distinguished from other tissue, with an area under the receiver operating characteristic (ROC) curve of 82%. No tumor was found in 15 patients with a predicted probability of necrosis over 90%. The predicted probabilities corresponded reliably with the observed probabilities (goodness-of-fit tests, P > .20), although a somewhat higher probability of necrosis was observed in patients treated with chemotherapy containing etoposide. Conversely, cancer could not reliably be predicted or adequately discriminated from mature teratoma. CONCLUSION: The predicted probabilities of necrosis have adequate reliability and discriminative power. These predictions may validly support the decision-making process regarding the need and extent of retroperitoneal lymph node dissection.
