Multimodal treatment of malignant sacrococcygeal germ cell tumors: a prospective analysis of 66 patients of the German cooperative protocols MAKEI 83/86 and 89.

PURPOSE: To evaluate a multimodal approach including surgery and cisplatinum chemotherapy for treatment of children with malignant sacrococcygeal germ cell tumors (GCT) and to compare adjuvant and neoadjuvant strategies in advanced tumors. PATIENTS AND METHODS: Between 1983 and 1995, 71 patients with malignant sacrococcygeal GCT were prospectively enrolled onto the German protocols for nontesticular GCT Maligne Keimzelltumoren 83/86 and 89. Five patients who received no chemotherapy (n = 2) or nonplatinum chemotherapy (n = 2) or who did not undergo tumor resection (n = 1) were excluded from this analysis. Among the 66 patients analyzed were 14 boys and 52 girls. The median age was 17.4 months (range, 7 months to 119 months). Median follow-up was 79 months (range, 4 months to 145 months). RESULTS: Fifty-two patients presented with locally advanced stage T2 tumors, and 30 patients had distant metastases at diagnosis. Patients received a median of eight cycles (range, four to nine cycles) of cisplatinum-based chemotherapy. Thirty-five patients underwent tumor resection at diagnosis and received adjuvant cisplatinum-based chemotherapy (group A). Thirty-one patients received up-front chemotherapy followed by delayed tumor resection (group B). Group B included more metastatic tumors than group A (group B, 19 of 31 patients; group A, 11 of 35 patients, P =.01). Preoperative chemotherapy facilitated complete tumor resections (group B, 20 of 31 patients; group A, five of 35 patients, P <.001) and avoided second-look surgery. Metastases at diagnosis and completeness of the first attempt of tumor resection were significant prognostic predictors; however, metastases were not predictive for patients treated with up-front chemotherapy. At 5 years follow-up, event-free survival was 0.76 +/- 0.05 (50 of 66 patients), and overall survival was 0.81 +/- 0.05 (54 of 66 patients). Four patients died as a result of therapy-related complications, and eight patients died of their tumors. Patients with locally advanced and metastatic tumors (T2b M1) fared better with neoadjuvant treatment [overall survival: 0.83 +/- 0.09 (16 of 19 patients) versus 0.45 +/- 0.15 (five of 11 patients), P =.01]. CONCLUSION: Even locally advanced and metastatic sacrococcygeal GCT can be successfully treated with up-front cisplatinum-based chemotherapy followed by delayed but complete tumor resection.     

Primary mediastinal germ cell tumors in children and adolescents: results of the German cooperative protocols MAKEI 83/86, 89, and 96.

PURPOSE: To evaluate children and adolescents with primary mediastinal teratoma and malignant germ cell tumors (GCTs). PATIENTS AND METHODS: Forty-seven patients from the German nontesticular GCT studies were analyzed (median age, 2.5 years; range, neonate to 17 years). Teratoma (n = 21) were resected, and no adjuvant treatment was given. Malignant GCTs (n = 26) were treated with cisplatin-based chemotherapy and resection. Three of 26 patients underwent radiotherapy. RESULTS: In all patients with teratoma, tumor markers were normal. Surgery of teratoma was complete in 17 of 21 patients and microscopically incomplete in four of 21 patients, and we observed no relapse after a median follow-up of 29 months. In 23 of 26 patients with malignant GCTs, alpha-fetoprotein and/or beta-human chorionic gonadotropin were elevated. Twelve of 26 patients received adjuvant chemotherapy after initial resection, which was complete in six of 12 patients, whereas delayed resection after preoperative chemotherapy was complete in 10 of 11 patients (P =.03). Four of six patients underwent second-look thoracotomy after incomplete primary surgery. Three of 26 patients did not undergo tumor resection. The final completeness of resection was the strongest prognostic indicator (event-free survival ?EFS, 0.94 +/- 0.06 v 0.42 +/- 0.33; P <.002). Local stage and distant metastases were not prognostically significant at the.05 level. For all malignant GCTs, the 5-year survival rate was 0.87 +/- 0.05 (median follow-up, 51 months), with an EFS of 0.83 +/- 0.05. CONCLUSION: The prognosis of mediastinal teratoma is excellent after complete or microscopically incomplete resection. In children with malignant GCT, the prognosis is favorable with a therapeutic strategy of delayed resection after preoperative chemotherapy. In most children, the diagnosis can be based on elevated tumor markers and imaging. Biopsy is indicated in nonsecreting GCT.     

Prognostic value of tumor size, metastases, extension into bone, and increased tumor marker in children with malignant sacrococcygeal germ cell tumors: a prospective evaluation of 71 patients treated in the German cooperative protocols Maligne Keimzelltumoren (MAKEI) 83/86 and MAKEI 89.

PURPOSE: To evaluate the prognostic value of metastases, extension into bone, and alpha-fetoprotein (AFP) elevation in children with malignant sacrococcygeal germ cell tumors (GCTs) prospectively collected in two cooperative Maligne Keimzelltumoren (MAKEI) protocols (83/86 and 89). PATIENTS AND METHODS: Between October 1983 and October 1995, 76 of 210 registered patients with sacrococcygeal primaries presented either with pure yolk sac tumor, embryonal carcinoma (EC), or yolk sac tumor and EC mixed with immature and mature teratoma elements. Stages T1 and T2 disease were diagnosed in 15 and 61 children, respectively, 41 patients had metastases, and 35 children presented with extension into bone. At diagnosis, 22 children had an AFP elevation of less than 10,000 ng/mL. Thirty-six children showed an AFP level between 10,000 and 100,000 ng/mL, and 12 patients had values of greater than 100,000 ng/mL. Five patients died of complication during treatment and were excluded from further evaluation. Seventy-one patients could be analyzed. RESULTS: The 5-year relapse-free survival rate (RFS, Kaplan-Meier) was 0.76 +/- 0.03 (54 of 71 patients; median observation time, 54 months after diagnosis). The RFS of patients with and without metastases was different, but not significantly so (0.71 v 0.82). The outcome of patients with extension into bone (n = 31) and without this extension (n = 40) was 0.71 versus 0.80 (RFS, 5 years). Above-normal AFP level had no prognostic significance (P =.52). CONCLUSION: In children with malignant sacrococcygeal GCTs treated with an intensive, short-interval, platinum-based regimen, the stage, extent of metastases, extension into bone, and AFP level had no prognostic significance.     

Radiation therapy for intracranial germinoma: results of the German cooperative prospective trials MAKEI 83/86/89.

PURPOSE: A multicenter prospective trial was conducted (Maligue Keimzelltümoren [MAKEI] 83/86/89) to assess outcome in intracranial germinoma after treatment with radiotherapy alone at reduced doses. PATIENTS AND METHODS: Between 1983 and 1993, 60 patients with histologically (n = 58) or cytologically (n = 2) confirmed germinoma were enrolled onto the study. Patients received radiotherapy alone (craniospinal axis/local boost). In the MAKEI 83/86 study (involving 11 patients), the dose to the craniospinal axis was 36 Gy and the dose to the tumor region was 14 Gy. In the MAKEI 89 study (involving 49 patients), doses were 30 and 15 Gy, respectively. RESULTS: Median patient age was 13 years (range, 6 to 31 years). Complete remission was achieved in all patients. The estimated (Kaplan-Meier) 5-year relapse-free survival rate was 91.0% +/- 3.9% at a mean follow-up of 59.5 months (range, 3 to 180 months); the estimated overall survival rate was 93.7% +/- 3.6%. Relapse occurred in five patients 10 to 33 months (mean, 18.4 months) after diagnosis (one patient developed a spinal canal metastasis and underwent salvage radiotherapy and chemotherapy; four patients had metastases outside the CNS and underwent salvage chemotherapy alone). Four patients died: one died from disease, two died from therapy-related complications, and one committed suicide. Acute complications with long-lasting sequelae were tumor or surgery related (three cases of blindness, six of reduced vision, two of hemiparesis). Psychosocial development was normal in the majority of patients. CONCLUSION: Radiotherapy directed toward the craniospinal axis or tumor site alone at decreased dose levels is effective. To reduce the risk of late side effects, further attempts to decrease total doses are justified. In cases of recurrent disease, chemotherapy administered outside the CNS is the treatment of choice.     

Treatment of malignant germ cell tumors.

In an unselected group of 278 patients with germ cell tumors, disease-free status was obtained in 97% by a treatment program including a surveillance-only strategy for stage I testicular cancer, and low-or high-dose cisplatinum-etoposide treatment for patients with more extensive disease. The overall follow-up period was a median of 40 months (range 20-62 months). At present 100% of patients with stage I disease, 91% with stage II disease, 86% with stage III disease, 75% with extragonadal germ cell tumors, and 3 of 3 patients with germ cell tumors in the ovary are alive and without disease. Among 36 patients treated with high-dose cisplatinum and etoposide there were six toxic deaths, four of them in patients with residual malignant disease. Three patients died of progressive disease. There were no toxic deaths among 54 patients with disseminated disease but without poor prognostic features who were treated with low-dose cisplatinum-etoposide; six of these patients died of progressive disease. It is concluded: 1) that surveillance is a feasible and reasonable strategy for patients with stage I disease; 2) that excellent survival results can be achieved with standard-dose cisplatinum-etoposide in patients with disseminated disease and a favorable prognostic profile; and 3) that disease-free status can be obtained in nearly all patients with poor prognostic features at the expense of significant toxicity. Standardized criteria for selection of patients with poor prognoses are needed. Randomized trials should be carried out to define the role of high-intensity treatment and, finally, measures to decrease or prevent serious toxicity should be explored.     

Treatment outcome of patients with brain metastases from malignant germ cell tumors

BACKGROUND: Multiinstitutional experience with the management of cerebral metastases from malignant germ cell tumors (MGCT) is presented. METHODS: Clinical data regarding brain metastases from MGCT at diagnosis (Group 1 [56 patients]) or after cisplatin-based chemotherapy (Group 2 [83 patients]) were collected retrospectively. All patients in Group 1 received "conventional" cisplatin-based chemotherapy supplemented by cerebral radiotherapy (36 patients) and/or neurosurgery (10 patients). In the patients in Group 2 cerebral metastases were detected a median of 9 months after the initiation of chemotherapy. Thirty-five patients received chemotherapy, 59 patients received radiotherapy, and 25 patients underwent neurosurgery. RESULTS: The 5-year cause specific survival rate in Group 1 was 45% (95% confidence interval [CI], 31-59%). Neurosurgery and the absence of extracerebral, nonpulmonary visceral disease, but not cerebral radiotherapy, were independent predictors of good prognosis. The 5-year cause specific survival rate in Group 2 was 12% (95% CI, 4-20%), but was 39% among patients with an isolated brain recurrence (24 patients). Radiotherapy, but not chemotherapy, represented an independent predictor of good prognosis together with brain metastases at first recurrence and the absence of extracerebral recurrence. CONCLUSIONS: Among patients with brain metastases at the time of diagnosis of an MGCT, cisplatin-based chemotherapy resulted in a 5-year cause specific survival rate of 45%, with cerebral radiotherapy having limited impact. The 5-year cause specific survival rate for all patients with brain metastases after cisplatin-based chemotherapy was 12%, but increased to 39% in patients with an isolated brain recurrence. Cerebral radiotherapy (and neurosurgery) represent essential treatment modalities for patients in whom brain metastases are diagnosed after induction chemotherapy.

Treatment and prognosis of patients with intracranial nongerminomatous malignant germ cell tumors: a multiinstitutional retrospective analysis of 41 patients

BACKGROUND: The relative roles of surgical resection, radiotherapy, and chemotherapy in the management of patients with intracranial nongerminomatous malignant germ cell tumors have been controversial. The authors retrospectively investigated the results of different treatment regimens in patients with these tumors. METHODS: The records of 41 patients who were treated between 1981 and 2001 were reviewed. They were grouped into patients with a good prognosis (n=3), an intermediate prognosis (n=24), and a poor prognosis (n=14) based on the histology of their tumors. Fifteen patients (37%) underwent surgical resection and received radiotherapy, and 26 patients (63%) also received chemotherapy. The median follow-up of 18 patients who remained alive was 61 months (range, 14-194 months). RESULTS: The 5-year actuarial overall survival rates for patients in the good prognosis, intermediate prognosis, and poor prognosis groups were 100%, 68%, and 8%, respectively. In the analysis, histology alone had a statistically significant impact on overall survival (P<0.0001). All 3 patients in the good prognosis group were treated successfully with surgical resection and radiotherapy. In the intermediate prognosis group, the 5-year actuarial overall survival rate was 44% for patients who underwent surgical resection and received radiotherapy (n=9) and 84% for patients who also received chemotherapy (n=15; P=0.01). Patients in the poor prognosis group who underwent surgical resection and received radiotherapy (n=3) or who underwent incomplete resection and received both radiotherapy and chemotherapy (n=8) all died of disease, whereas 2 of 3 patients who underwent macroscopic total resection and received both radiotherapy and chemotherapy survived free of disease. CONCLUSIONS: The treatment of patients with intracranial nongerminomatous malignant germ cell tumors should be based on tumor histology. For patients who had a good prognosis (mature teratoma with germinoma), surgical resection and radiotherapy were sufficient; however, for patients in the intermediate prognosis group, multimodal treatment, including surgical resection, radiotherapy, and chemotherapy, was effective. Conversely, for patients in the poor prognosis group, more intensive multimodal treatment, including macroscopic total resection, may improve the survival rate.     

Treatment of malignant germ cell tumors of the ovary with bleomycin, etoposide, and cisplatin.

Since 1984, we have treated 26 patients with malignant ovarian germ cell tumors with a combination of bleomycin, etoposide (VP-16), and cisplatin (BEP) at The University of Texas MD Anderson Cancer Center (UTMDACC). The median age of the patients was 19 years (range, 8 to 32). All patients underwent initial surgery (unilateral salpingo-oophorectomy in 14, unilateral salpingo-oophorectomy plus abdominal hysterectomy in one, and bilateral salpingo-oophorectomy with or without hysterectomy in 11 patients). Twenty patients had no residual disease, three had less than or equal to 2 cm (one each, dysgerminoma, mixed, and immature teratoma), and three had more than 2 cm lesions (two dysgerminomas, one endodermal sinus tumor). Fourteen patients had pure dysgerminoma (five, stage I; one, stage II; six, stage III; and two, recurrent), and 12 had nondysgerminomatous tumors (five, stage I; two, stage II; three, stage III; and two, recurrent). All four patients with clinically measurable disease had a complete response. All four patients who underwent second-look laparotomy had negative findings. Twenty-five patients (96%) remain in sustained remission 10.4 to 54.4 months from the start of chemotherapy. One patient died of progressive disease 14 months after beginning chemotherapy. We conclude that the BEP regimen has excellent activity and acceptable toxicity in patients with malignant ovarian germ cell tumors.     

Nongerminomatous malignant germ cell tumors in children. A review of 89 cases from the Pediatric Oncology Group, 1971-1984

Clinical and morphologic features of 89 cases of childhood yolk sac tumor (YS) and embryonal carcinoma (EC) (29 associated with teratomas) submitted to the Rare Tumor Registry of the Southwest Oncology Group (1971-1979) or the Pediatric Oncology Group (1980-1984) between 1971 and 1984 were reviewed and submitted to statistical analysis. This review showed an improved survival for each 5-year period regardless of tumor site, no statistically significant difference between "pure" tumors and those mixed with other teratomatous components, no statistically significant difference between YS and EC in children, a better than reported prognosis for sacrococcygeal tumors occurring after the neonatal period, a particularly poor prognosis for neonatal "benign" sacrococcygeal teratomas resected without coccygectomy when they recur as YS, excellent survival for all testicular tumors regardless of age or the presence of EC, and the occurrence of mediastinal tumors in females.     

Treatment of nondysgerminomatous ovarian germ cell tumors: an analysis of 69 cases.

BACKGROUND: Combination chemotherapy has dramatically improved the prognosis of patients with nondysgerminomatous ovarian germ cell tumors (NDOGCT). However, guidelines are needed for the identification of patients at risk of relapse. METHODS: The authors performed a retrospective analysis of women with NDOGCT managed during the period 1970-1994 at the Royal Marsden Hospital and other hospitals of the London Gynaecological Oncology Group. RESULTS: Sixty-nine women were included; their median follow-up was 5.7 years (minimum, 12 months). The median age was 21 years (range, 4-44 years), with a histology of immature teratoma (IT) for 17 patients, endodermal sinus tumor (EST) for 20 patients, and mixed tumors for 32 patients. Thirty-five patients (51%) had Stage I disease. Nine patients with Stage I tumors were observed without further therapy (six with IT and three with mixed tumors), and one relapsed. Seven patients received non-platinum-based chemotherapy, and four relapsed. A total of 52 patients were treated with platinum-based chemotherapy, with relapse free and overall survival rates of 87% (95% confidence interval [CI], 73-93%) and 84% (95% CI, 70-91%), respectively. Of these patients, relapse was seen in 0 of 9 IT patients, 1 of 25 patients with mixed tumors, and 6 of 18 EST patients. With alpha-fetoprotein (AFP) > 1000 kU/L, relapse was seen in 6 of 18 patients compared with 1 of 33 relapses with lower AFP levels. In multivariate analysis, including all patients who received chemotherapy, AFP >1000 kU/L (P = 0.001) and non-platinum-based chemotherapy (P = 0.005) were associated with relapse. When only patients given platinum-based treatment were considered, EST histology (P = 0.003) and AFP >1000 kU/L (P = 0.003) were associated with relapse in univariate analysis; however, these factors were linked. No malignant tumor was found at second-look surgery performed on 24 patients. Of 26 women assessable for fertility, 24 subsequently recommenced regular menstrual function, and 11 patients had pregnancies. CONCLUSIONS: Platinum-based chemotherapy has been confirmed to be effective in the management of patients with NDOGCT. Relapses were principally seen among patients with AFP >1000 kU/L or pure EST histology. Efforts to improve outcome need to focus on patients with EST, whereas less intensive management strategies may be appropriate for some patients with IT.     

Treatment results in localized primary gastric lymphoma: data of patients registered within the German multicenter study (GIT NHL 02/96).

PURPOSE: In the prospective study 02/96 on primary GI lymphoma, we have collected data on histology, clinical features, and treatment results. In particular, in stages I and II localized primary gastric lymphoma (PGL), our objectives were to reduce treatment intensity and to confirm our hypothesis from study 01/92, which maintained that an organ-preserving approach is not inferior to primary surgery. PATIENTS AND METHODS: Patients receiving radiotherapy and/or chemotherapy were stratified for histologic grade, stage, and whether surgery had been carried out or not (as decided by each participating center). Patients with aggressive PGL received six cycles of CHOP-14 (cyclophosphamide, doxorubicin, vincristine, and prednisone) followed by involved-field radiotherapy (40 Gy). Patients with indolent PGL (including patients experiencing treatment failure with antibiotic therapy for Helicobacter pylori) were treated with extended-field radiotherapy. The volume depended on stage. The irradiation dose was 30 Gy, followed by a boost of 10 Gy (the latter omitted after complete resection) to the tumor region. RESULTS: Seven hundred forty-seven patients were accrued. Of these patients, 393 with localized PGL were treated with radiotherapy and/or chemotherapy only or additional surgery between December 1996 and December 2003. The survival rate at 42 months for patients treated with surgery was 86% compared with 91.0% for patients without surgery. CONCLUSION: In this nonrandomized study (02/96), we reproduced the previous results of study 01/92 showing no disadvantage for an organ-preserving treatment. Therefore, primary stomach resection should be questioned.     

Treatment of malignant nondysgerminomatous germ cell tumors of the ovary with vinblastine, bleomycin, and cisplatin

Fifteen patients with malignant nondysgerminomatous germ cell tumors of the ovary seen at The University of Texas M. D. Anderson Hospital and Tumor Institute at Houston, were treated with a combination of vinblastine, bleomycin, and cisplatin (VBP). All patients underwent initial surgery: biopsy alone in one patient, unilateral salpingo-oophorectomy in ten patients, and bilateral salpingo-oophorectomy with or without hysterectomy in four patients. Seven patients received VBP as primary postoperative therapy. One patient died of progressive disease at 15 months following diagnosis. The other six patients are alive without evidence of disease 9 to 47 months from the time of diagnosis. Eight patients received VBP as second-line treatment; three patients had a complete response to therapy and are surviving disease-free 41 to 71 months from the time of diagnosis. Four patients treated secondarily had a partial response; three of these patients subsequently developed progressive disease and died, while one patient survived after undergoing salvage therapy with an etoposide-containing regimen. One patient had no discernible response to VBP therapy and died. The VBP regimen represents an aggressive, moderately toxic, short-term combination regimen that has promising activity against malignant germ cell tumors of the ovary.     

Treatment of malignant nondysgerminomatous germ cell tumors of the ovary with vincristine, dactinomycin, and cyclophosphamide

Eighty patients with malignant nondysgerminomatous germ cell tumors of the ovary were treated with the combination of vincristine, dactinomycin, and cyclophosphamide (VAC) at The University of Texas M.D. Anderson Hospital and Tumor Institute. All patients underwent initial surgery: biopsy alone in 3 patients, unilateral salpingo-oophorectomy in 48 patients, and bilateral salpingo-oophorectomy with or without hysterectomy in 29 patients. Sixty-six patients received VAC as primary postoperative therapy; 46 patients (70%) achieved a sustained remission. VAC produced sustained remission in 86% of patients with Stage I, 57% of patients with Stage II, 50% of patients with Stage III, and no patients with Stage IV disease. For patients with Stage I disease, survival rates did not differ among histologic groups, but in advanced disease, patients with immature teratoma did significantly better than the others. Four of the 20 patients who failed primary VAC therapy were salvaged with other therapies, and 8 of 14 treated with VAC after relapse or failure of other treatments were salvaged. Although VAC produces excellent results with very acceptable toxicity in patients with Stage I disease and advanced immature teratoma, survival of patients with other advanced histologic types has been disappointing. The authors are therefore treating this latter group with alternative therapy such as vinblastine, bleomycin, and cisplatin with the goal of achieving improved efficacy.

Vinblastine, bleomycin, and cisplatin in malignant germ cell tumors of the ovary

Fourteen patients with malignant ovarian germ cell tumors were treated with vinblastine, bleomycin, and cisplatin. A complete clinical response was achieved in all 14 patients; however, 1 patient had small macroscopic disease present at second-look laparotomy. One patient died of bleomycin pulmonary toxicity. The remaining 13 patients are alive and free of disease from 20 months to 8 years and 8 months after initial diagnosis. Serum alpha-fetoprotein and beta-human chorionic gonadotropin levels were monitored in all patients and were found to be reliable indicators of response to treatment and disease status. The uninvolved ovary was preserved in seven patients without compromising the response to treatment, and one patient subsequently became pregnant. Vinblastine, bleomycin, and cisplatin chemotherapy appears to be a safe, effective combination and is recommended as the primary treatment of choice in the management of patients with malignant ovarian germ cell tumors.     

Primary malignant extragonadal germ cell tumors. An analysis of the effect of the effect of radiotherapy

A retrospective analysis was performed on all patients diagnosed with biopsy-proven extragonadal germ cell tumors at the University of Virginia (Charlottesville, VA), The Medical University of South Carolina (Charleston, SC), the Bethesda Naval Hospital (Bethesda, MD), and The Medical College of Virginia (Richmond, VA) for the time period of January 1965 to December 1984. A total of 54 patients were treated with the initial sites of presentation observed: mediastinum, 26; central nervous system, 14; retroperitoneum, eight; and sacrococcygeal region, six. Megavoltage irradiation was used in 44 patients with a dose range of 2400 to 5580 cGy (mean, 4213 cGy). With a minimum follow-up of 4.0 years and a mean follow-up of 10.8 years, the 5-year actuarial survival for the entire population was 57.8%. Local control was achieved in 26 of 44 (59%) of the irradiated population. Factors of prognostic significance included histologic type at presentation, site of presentation, and radiation doses greater than or equal to 4000 cGy. Radiotherapy appears to be an effective modality in patients with extragonadal seminomas; however, the nonseminomatous tumors do not appear to be as radioresponsive.
