Effectiveness and morbidity of secondary retroperitoneal lymph node dissection after chemotherapy in testicular tumors.

Addition of surgery to cytoreductive chemotherapy has increased the number of patients with complete remission after advanced testicular cancer. In this report, we present the morbidity of complete retroperitoneal lymph node dissection following aggressive chemotherapy in 10 of these patients. Although no mortality and no postoperative major complications were registered in our series, there were high morbidity rates during operation represented by single or multiple dehiscences of the inferior vena cava and/or renal vein (7 cases), aortic graft for aortic dehiscence (1 case), partial sigmoidectomy after inferior mesenteric artery division (1 case with previous retroperitoneal radiotherapy), total nephrectomy (2 cases), and suprarenalectomy (5 cases). Because the overall possible benefit of chemotherapy-surgery combination was seen in 7 of our 10 stage III-B4 patients, we believe that the combined approach is the best option for treating advanced retroperitoneal testicular cancer and its results justify the morbidity due to lymphadenectomy.

Adjuvant chemotherapy combination of vinblastine, actinomycin D, Bleomycin, and Chlorambucil following retroperitoneal lymph node dissection for stage II testis tumor.

In an attempt to reduce recurrence of nonseminomatous germ cell tumors of testis stage II, 62 patients were treated with vinblastine, actinomycin D, bleomycin, and chlorambucil after retroperitoneal lymph node dissection. Of the patients, 84% have remained in complete remission with median follow-up of three years: 33/33 stage II-A (N-1,N-2A) and 19/29 (66%) stage II-B (N-2B,N3). The relapse rate in patients who had histologic evidence of extranodal extension of the tumor (N-3) was 54% (7/13). This program did not cause any serious toxicity. Adjuvant chemotherapy is effective in reducing relapses. More recently, with the current availability of chemotherapy with a high efficacy for control of disseminated disease, patients with resected stage II-A (N-1,N2A) have been followed closely and treated only if they developed evidence of recurrence. Patients with resected stage II-B (N-2B,N-3) have been placed on a more aggressive adjuvant program.

Retroperitoneal lymph node dissection for nonseminomatous germ cell testicular cancer: impact of patient selection factors on outcome.

PURPOSE: To investigate the impact of patient selection criteria on the outcome of patients with nonseminomatous germ cell testicular cancer (NSGCT) treated by primary retroperitoneal lymph node dissection (RPLND). Since 1999, our criteria have excluded patients with persistent postorchiectomy elevation of serum tumor markers (STM) or clinical stage (CS) IIB disease from RPLND. PATIENTS AND METHODS: Between 1989 and 2002, 453 patients underwent primary RPLND at our institution for CS I to IIB NSGCT. Patient information was obtained from a prospective database. Retroperitoneal pathology and relapse rates were compared for patients treated before and after application of the current selection criteria in 1999. RESULTS: By excluding patients with elevated STM or CS IIB disease after 1999, the proportion of pathologic stage II patients with low-volume (pN1) retroperitoneal disease increased significantly (40% before 1999 v 64% after 1999; P = .01), without significantly affecting the rate of retroperitoneal teratoma (21% v 22%, respectively; P = .89) or pathologic stage I disease (56% v 67%, respectively; P = .06). For patients who did not receive adjuvant chemotherapy, the 4-year progression-free probability improved significantly from 83% before 1999 (95% CI, 79% to 88%) to 96% after 1999 (95% CI, 91% to 100%; P = .005). Elevated postorchiectomy STM (P < .0001), clinical stage (P = .0002), and pre-1999 RPLND (P = .05) were independent pretreatment predictors of progression. CONCLUSION: Excluding patients with CS IIB disease or elevated postorchiectomy STM from primary RPLND has had a favorable impact on the extent of retroperitoneal disease and has significantly reduced the risk of relapse after RPLND. For patients with normal STM and CS I to IIA disease, the low rate of systemic progression and 22% incidence of retroperitoneal teratoma supports RPLND as the preferred primary intervention.

Quality of life after laparoscopic and open retroperitoneal lymph node dissection in clinical Stage I nonseminomatous germ cell tumor: a comparison study.

OBJECTIVES: To compare the postoperative quality of life (QOL) and reconvalescence in patients with clinical Stage I nonseminomatous germ cell tumor (NSGCT) after laparoscopic retroperitoneal lymph node dissection (L-RPLND) and the open procedure (O-RPLND). METHODS: Twenty-one patients with NSGCT who underwent transperitoneal L-RPLND were matched and compared with 29 patients who underwent O-RPLND. The operative, QOL, and recovery data and complications and cure rates were analyzed for both groups. RESULTS: The mean follow-up time for the L-RPLND and O-RPLND groups was 14 months (range 6 to 20) and 26 months (range 8 to 38), respectively. No major complication requiring open surgical revision or prolongation of hospitalization was observed intraoperatively or postoperatively in either group. However, the early and late minor postoperative complications were significantly greater in the O-RPLND group than in the L-RPLND group (P <0.001). The L-RPLND patients had a significantly shorter hospitalization, greater QOL scores, and a faster return to normal activities than did the O-RPLND patients (all P <0.001). CONCLUSIONS: L-RPLND for patients with clinical Stage I NSGCT is a safe and efficacious procedure, with a faster reconvalescence and greater postoperative QOL than after O-RPLND.

Pathologic findings and clinical outcome of patients undergoing retroperitoneal lymph node dissection after multiple chemotherapy regimens for metastatic testicular germ cell tumors.

BACKGROUND: Postchemotherapy surgery is an essential component in the management of patients with metastatic germ cell tumors (GCT). The authors assessed their institutional experience of retroperitoneal lymph node dissection (RPLND) after multiple chemotherapy regimens for advanced GCT. METHODS: By analyzing the institutional prospective surgical database from 1989 to 2004, 71 patients were identified who underwent RPLND after multiple chemotherapy regimens. Clinicopathologic and treatment trends were characterized, and predictors of disease-specific survival (DSS) were evaluated. RESULTS: The histologic findings at RPLND were fibrosis in 36 men (51%), GCT in 20 men (28%), and teratoma in 15 men (21%). Patients who underwent RPLND from 1989 to 1998 (n = 47), compared with patients who underwent RPLND from 1999 to 2004 (n = 24) were more likely to have GCT (36% vs 13%; P = .04). Patients who received taxane-containing chemotherapy regimens as salvage therapy had lower rates of GCT at RPLND (14% vs 42%; P = .01), higher rates of fibrosis (63% vs 39%; P = .04), and similar rates of teratoma (31% vs 33%; P = .9). The 5- and 10-year DSS rates were 74% (95% confidence interval [95% CI], 62-86%) and 70% (95% CI, 56-84%), respectively. Five-year DSS based on worst histology of RPLND and extraretroperitoneal specimens was 87% (95% CI, 75-99%) for fibrosis, 87% for teratoma (95% CI, 63-100%), and 47% for GCT (95% CI, 23-71%; P = .004). On multivariable analysis, retroperitoneal mass > or = 5 cm and GCT were predictors of worse DSS (P = .03 and P = .005, respectively). CONCLUSIONS: Taxane-based salvage chemotherapeutic regimens appear to have decreased the rate of GCT at RPLND. The current data support RPLND in select patients after salvage chemotherapy, because a considerable proportion has teratoma or GCT, and the 10-year DSS rate after resection is 70%.

Incidence and clinical outcome of patients with teratoma in the retroperitoneum following primary retroperitoneal lymph node dissection for clinical stages I and IIA nonseminomatous germ cell tumors.

PURPOSE: We determined the incidence and clinical outcome of patients with clinical stages I and IIA nonseminomatous germ cell tumors (NSGCT), and teratoma in the retroperitoneum following primary retroperitoneal lymph node dissection (RPLND). MATERIALS AND METHODS: Between January 1989 and February 1998, 294 patients with clinical stages I (209) and IIA (85) underwent primary RPLND at our institution. The primary tumor had teratomatous elements in 179 (61%) cases. Median followup was 27.8 months. RESULTS: The overall incidence of teratoma in the retroperitoneum was 9% (25 of 294), and 21% (25 of 118) in patients with pathological stage II disease. The incidence of teratoma in the retroperitoneum increased from 3% (6 of 209) in clinical stage I to 22% (19 of 85, chi-square test p <0.0001) in clinical stage IIA. The incidence of teratoma in patients with pN1/N2/N3 disease increased from 9% (6 of 64) in clinical stage I to 35% (19 of 54) in clinical stage IIA (chi-square test p = 0.0006). All 25 patients with pathological stage II and teratoma in the retroperitoneum have no evidence of disease. CONCLUSIONS: The incidence of teratoma in the retroperitoneum increases with clinical and pathological stage. Teratomatous elements in the orchiectomy specimen predict teratoma in clinical and pathological stage II NSGCT. The absence of teratoma in the primary tumor does not preclude its presence in the retroperitoneum. Primary RPLND avoids the persistence of chemoresistant teratoma in the retroperitoneum, contributes to the high cure rate of patients with low stage NSGCT and decreases the potential for late relapse.

Pathologic findings and therapeutic outcome of desperation post-chemotherapy retroperitoneal lymph node dissection in advanced germ cell cancer.

Increased serum tumor markers after cisplatin-based chemotherapy have usually been considered a contraindication to surgery because of the presence of persistent active germ cell elements. However, a select population of patients with elevated serum tumor markers have undergone post-chemotherapy retroperitoneal lymph node dissection (RPLND) with curative intent. We evaluated the role of surgery to resect retroperitoneal-only marker positive tumor. Long-term survival was observed in 50% of patients. Residual germ cell cancer was identified in 50% of patients, with a third alive at 5 years with no observed benefit from adjuvant chemotherapy. Select patients with increased tumor markers after chemotherapy are cured with surgery.

Management of adult Leydig-cell testicular tumors: assessing the role of laparoscopic retroperitoneal lymph node dissection.

BACKGROUND AND PURPOSE: Leydig-cell tumors represent <5% of malignant testicular tumors in adults. Orchiectomy is curative in approximately 90% of cases; however, the remaining men can develop metastases refractory to chemotherapy and radiation. We evaluated the role of laparoscopic retroperitoneal lymph node dissection (RPLND) in adult Leydig-cell tumors. PATIENTS AND METHODS: Between 1999 and 2001, laparoscopic RPLND was performed with four transperitoneal ports within a unilateral template for six patients with pure Leydig-cell tumors. Presenting signs and symptoms, operative time, blood loss, intraoperative complications, postoperative complications, length of hospitalization, pathology reports, ejaculatory function, and survival were reviewed retrospectively. RESULTS: Laparoscopic RPLND was successful, without open conversions or reinterventions. Two vascular injuries occurred during dissection; additional intraoperative complications were not observed. Postoperatively, one patient developed erysipelas, but no other postoperative complications were recorded. The mean operative time was 190 minutes, and the mean length of hospitalization was 4.3 days. Pathologic analysis of lymph nodes revealed no evidence of metastatic Leydig-cell tumor. At 12 months' mean follow-up (range 3-29 months), no recurrences have been identified. CONCLUSIONS: Laparoscopic RPLND is a safe, minimally invasive procedure for Leydig-cell tumors. Additional clinical experience is required to evaluate its effectiveness for pathologic stage II tumors and to determine if a therapeutic advantage can be realized with a protocol employing laparoscopic RPLND for adult Leydig-cell tumors.

[Retroperitoneal lymph node dissection for testicular tumor with renal autotransplantation: a case report].

A case of testicular tumor (embryonal cell carcinoma with choriocarcinoma) in a 42-year-old man treated with renal autotransplantation is presented. After four courses of chemotherapy (carboplatin, vinblastine and bleomycin), we performed retroperitoneal lymph node dissection. At the operation, one of the swelling lymph nodes involved left renal artery completely, so we performed left renal autotransplantation and promoted more effective lymph node dissection. After the operation, renal function was impaired but returned completely in a short time. Autotransplantation provides excellent bench visualization of renal lesions and stable graft function. Therefore, this procedure should be taken into consideration when nephrectomy cannot be avoided.

Peritoneal carcinomatosis in germ-cell tumor: relations with retroperitoneal lymph node dissection.

Peritoneal carcinomatosis from germ-cell tumor has rarely been described, and thus remains largely unknown. We report here five cases involving this entity. All five patients had embryonal carcinoma in their primary germ-cell tumor. Four of them had undergone retroperitoneal lymph node dissection (RPLND), and viable malignant cells were found. RPLND was performed for relapses (n = 3) and as primary therapy for stage II disease (n = 1). The peritoneum was the only site of relapse in three patients, and was associated with pleural effusion in one. The time to relapse after RPLND ranged from 6 to 14 months. One patient sustained injury to lymph nodes during RPLND, and another patient had a peritoneal xanthelasma. The only three patients already described in the literature underwent RPLND or surgical biopsy. All these observations suggest a striking relation between RPLND and occurrence of subsequent peritoneal carcinomatosis.

Clinical stage I nonseminomatous germ cell tumors of testis. Observation vs retroperitoneal lymph node dissection.

Between 1980 and 1989, 186 patients with testicular tumors were seen at Roswell Park Memorial Institute. Of these, 66.6 percent (124/186) were diagnosed to have nonseminomatous germ cell tumors (NSGT) and 22 percent (41/186) were clinically determined to have Stage I disease. Patients with clinical Stage I NSGT either underwent observation or retroperitoneal lymph node dissection (RPLND). Recurrence in the observation group of patients was 23.5 percent (4/17) between four and eighteen months (mean 10 months) with the retroperitoneum being the most common site. All but 1 patient (80%) were salvaged with platinum-based combination chemotherapy. Of the 24 patients who had RPLND, 21 percent (5/24) had a false-negative metastatic evaluation. All the patients who had surgically documented metastatic disease were successfully treated with chemotherapy. The similar recurrence rates in the observation group and the false-negative RPLND group suggest that the failure rate in the observation group is a result of the inability to stage accurately patients with NSGT. RPLND continues to be the standard therapy in patients with clinical Stage I disease. Despite its high recurrence rate, observation should, however, be offered to well-motivated and selected patients since salvage platinum-based combination chemotherapy is very effective and the majority of patients in this group are spared a major operative procedure.

Chemotherapy in advanced seminoma and the role of postcytostatic retroperitoneal lymph node dissection.

Between 1979 and 1992, 79 patients with seminoma were treated at our institution. Nineteen of these patients with advanced seminoma were treated with cisplatin-based chemotherapy (stage IIA, n = 2; stage IIB, n = 6; stage IIC, n = 2; stage III, n = 5 [2 with primary extragonadal tumor site]; relapse, n = 5 [1 with previously stage III seminoma]). One patient died of progressive disease 3 months after treatment with chemotherapy and retroperitoneal lymph node dissection (RPLND) which had led initially to a complete clinical response. Another patient (62 years old) died of an acute heart failure due to a sepsis caused by chemotherapy. Treatment of the other 17 patients was successful. Ten patients with a residual retroperitoneal mass after inductive chemotherapy underwent a RPLND. In 1 case viable seminoma (diameter of the residual mass 5 cm), in 4 cases necrotic tumor tissue, and in 5 cases fibrosis was diagnosed histopathologically. The 2 patients with extragonadal seminoma showed complete responses after surgery and chemotherapy. In conclusion, in patients with advanced seminoma, inductive cytostatic therapy seems to be the best treatment regimen. Residual retroperitoneal masses after chemotherapy with a diameter of > 3 cm should be treated with RPLND.

Seminoma with elevated human chorionic gonadotropin. The case for retroperitoneal lymph node dissection.

An elevated serum level of human chorionic gonadotropin (HCG) in a patient whose primary tumor histologically appears to be a pure seminoma implies the presence of syncytiotrophoblastic giant cells either detectable by careful step sectioning of the primary tumor or present in metastatic disease. Inasmuch as the malignant potential and radioresponsiveness of syncytiotrophoblastic giant cells are unknown and the serum elevation of HCG may signal metastatic embryonal carcinoma, retroperitoneal lymph node dissection with adjuvant chemotherapy dependent on pathologic staging should be considered for patients with seminoma and postorchiectomy elevated HCG levels. An illustrative case is herein reported.

Teratoma in primary testis tumor reduces complete response rates in the retroperitoneum after primary chemotherapy. The case for primary retroperitoneal lymph node dissection of stage IIb germ cell tumors with teratomatous elements.

BACKGROUND: Recent advances in the therapy of advanced testicular nonseminomatous germ cell tumors (NSGCT) have resulted in increased attention to avoiding double therapy in cases where single modality therapy will suffice. METHODS: Over an 8-year period, 104 patients with Stage II and III testicular NSGCT received primary chemotherapy. Seventy-nine patients had retroperitoneal lymph nodal metastases, 33 of whom had a radiologic complete response, 43 a radiologic incomplete response, and 3 were not re-evaluated after induction chemotherapy. Thirty-nine patients underwent retroperitoneal lymph node dissection (RPLND). The radiologic and pathologic response of the nodes to primary chemotherapy was correlated with tumor burden (lymph node metastasis size < or = 2 cm, 2.1-5 cm, 5.1-10 cm, and >10 cm), primary tumor pathology, and prechemotherapy marker levels. RESULTS: Larger initial lymph node size, metastases size, the presence of teratoma in the primary tumor, and prechemotherapy alpha-fetoprotein (alpha-FP) > 80 mg/L and beta-HCG (bHCG) 10000 IU/L were found to correlate significantly with an incomplete radiologic response. Lymph node metastases size was the only independent prognostic factor on multivariable logistic regression analysis. Prechemotherapy alpha-FP > 80 mg/L and beta-HCG > 10000 IU/L were associated with the presence of teratoma or carcinoma in the retroperitoneal nodes. The presence of teratoma in the primary tumor is associated with a higher incomplete response rate and residual teratoma in the retroperitoneal lymph nodes after primary chemotherapy. CONCLUSIONS: Predictors of need for postchemotherapy RPLND include large lymph node metastasis size and presence of teratomatous elements in the primary tumor. To reduce the need for and morbidity of double therapy, patients with low volume clinical Stage II, NSGCT and teratomatous elements in the primary tumor are arguably better served by primary RPLND.

Retroperitoneal lymph node dissection for high-risk stage I and stage IIA seminoma.

INTRODUCTION: The clinical results of radiotherapy in low-stage seminoma are excellent with negligible early morbidity. However, in a long-term follow-up various complications may occur. On the other hand, experience in nonseminomas shows that surgical morbidity has decreased markedly after invention of a nerve-sparing technique. These issues served as a rationale for us to perform the primary retroperitoneal lymph node dissection (RPLND) in seminoma patients. MATERIALS AND METHODS: Fourteen pure seminoma patients (10 high-risk stage I and four with clinical stage IIA) underwent nerve-sparing RPLND from September, 1997 to December, 2002. RESULTS: Pathological evaluation revealed lymph node involvement in three out of 10 clinical stage I and in all four stage IIA cases. The patients' acceptance of the surgery was good. Minor intra- and early postoperative complications were observed in two cases. Antegrade ejaculation was preserved in all patients. No retroperitoneal or distant recurrences have been observed. All patients were free of disease with the mean follow-up period of 56 months. CONCLUSION: The excellent results and minimum morbidity of nerve-sparing RPLND together with the increased concerns on late complications of radiotherapy may turn the preference of surgery in low-stage seminoma into the subject of future discussion.

Does retroperitoneal lymph node dissection have a curative role for patients with sex cord-stromal testicular tumors?

BACKGROUND: Sex cord-stromal tumors account for < 5% of all adult testicular tumors, and 10% are malignant. Due to the limited reported experience, there is no agreement on the best management, especially in patients who have tumors with malignant pathologic features or who present with metastatic disease. The authors attempt to evaluate the role of retroperitoneal lymph node dissection (RPLND) in the management of patients with these malignant sex cord-stromal tumors. METHODS: Reviewing the Indiana University testis cancer registry revealed 17 patients who underwent RPLND for sex cord-stromal tumors. Pathology was reviewed for features suggestive of malignancy. The data examined included clinical and pathologic stage, surgical procedure, additional therapy received, and outcome. RESULTS: Pathology included Leydig tumors in six patients, Sertoli tumors in four patients, sex cord-stromal tumors in five patients, a granulosa cell tumor in one patient, and a poorly differentiated non-germ cell tumor in one patient. Nine patients had histologic features suggestive of malignancy. Clinical stage at surgery was Stage I in nine patients and Stage IIA-IIIA in eight patients. Patients underwent modified or bilateral RPLND. Nine patients had pathologic Stage I tumors, and the remaining eight patients and had pathologic Stage IIB-IIIA tumors. Follow-up ranged from 8 months to 11 years. Of the eight patients with Stage II-III disease, six patients eventually died of metastatic disease despite additional radiotherapy and/or chemotherapy. CONCLUSIONS: Sex cord-stromal tumors have a potentially aggressive malignant behavior that is difficult to predict based on clinical and pathologic features. Although the therapeutic role of RPLND in patients with small-volume metastatic retroperitoneal tumors is unclear, RPLND remains an option to be performed immediately after orchiectomy, especially in patients who have tumors with malignant features and/or small-volume metastatic disease.

Postchemotherapy retroperitoneal lymph node dissection is effective therapy in selected patients with elevated tumor markers after primary chemotherapy alone.

OBJECTIVES: Elevated tumor markers after primary chemotherapy for metastatic testis cancer are usually an indication of persistent cancer. Subsequent treatment has usually been salvage chemotherapy. This article examines the possibility that selected patients can achieve long-term disease-free survival with surgery alone. METHODS: Using a computerized data base of 627 postinduction chemotherapy retroperitoneal lymph node dissections (PC-RPLND), 23 patients with elevated tumor markers who have undergone PC-RPLND after induction chemotherapy alone were identified. Of the 23 patients, 15 were considered candidates for salvage chemotherapy, but instead underwent salvage surgery. Case histories were reviewed to establish selection criteria for PC-RPLND. RESULTS: Eight patients originally presented as clinical Stage C, 6 as clinical Stage B-3, and 1 as clinical Stage B-2. All patients initially received cisplatin combination chemotherapy. Twelve patients had an elevated alpha-fetoprotein level and 3 patients had an elevated beta human chorionic gonadotropin level prior to PC-RPLND. Seven patients had rising markers at the time of PC-RPLND. Seven patients had teratoma only in their resected specimen and all have no evidence of disease (NED) at a median of 35 months. Two patients had necrosis only in their RPLND specimen and both are NED at 10 and 42 months. Six patients had cancer in their resected specimen and 2 are NED, 1 is alive with disease, and 3 are dead of disease. Five of the 6 patients with cancer in their resected specimen were the only patients who received postoperative chemotherapy. CONCLUSIONS: Some patients with modest elevations of tumor markers after induction chemotherapy may only have teratoma or necrosis in the postchemotherapy resected specimen. These patients (n = 9) remain continuously NED. Patients who undergo salvage surgery and have cancer in the resected specimen do less well, but selected patients can be cured with this modality and thus avoid the morbidity of salvage chemotherapy.
