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.

Background: Cervical cancer is ranked as the most common cancer in Indian women, second most common cancer worldwide and the leading cause of death in the developing countries. In the developing countries majority of the patients are diagnosed at locally advanced stages. The standard treatment of locally advanced cervical cancer is concomitant chemoradiation (CTRT) using platinum based chemotherapy. However, some randomized studies have shown improved results for patients receiving neoadjuvant chemotherapy (NACT) followed by surgical resection in comparison to patient receiving radiation alone. The present study was designed to compare response to the treatment and survival of and NACT followed by radical surgery (RS) with CTRT in the patients of uterine cervix of a tertiary cancer care centre. Patients and Methods: Retrospective study was performed in locally advanced/advance stage patients of cervix UTERI registered in the institute between years 2009 to 2013. Patients were included in the two groups, group A consists of 89 patients who have received NACT + RS and 67 patients in group B who have received CTRT. Clinical records were reviewed with particular reference to presenting complaint, clinical stage, response to the therapy, disease free survival and overall survival. Statistical analysis was done using SPSS version 22. Results: In the neoadjuvant group (group A) (n=89) the median age of patients was 53 years (range 31-80 years), most of the patients (70%) were presented with complaint of postmenopausal bleeding. Of the total patients, 69 (77.5%) underwent to radical surgery and 5 (8.5%) received radiotherapy after NACT. From 69 patients, who had undergone to surgery, 54 (78.3%) had also received radiation. The overall response to induction chemotherapy was 84%. In the chemo radiation group (group B) (n=65) median age was 56 years (33-75 years). Vaginal bleeding (34%) followed by postmenopausal bleeding (32%) was major presenting complaint in this group. Overall response to the complete treatment was 91%. The median follow up time was 14.3 months in group A and 12.2 months in group B. The disease free survival for NACT group was 32 months (95% CI 26.8-36.5) whereas for CTRT group it was 28 months (95% CI 23.5-33) with 12 and 13 recurrences per group (p = .226). In NACT group overall survival was 46.2 months (95% CI 44-48.3) and for CTRT group it was 38.3 months (95%CI 36.6-40) with 3 and 2 deaths per group (p=.883). Conclusion: Present study shows comparable results, with no difference in survival between both the groups. However, NACT + RS group had showed better disease free and overall survival than another group. Further studies should be performed with larger number of patients and longer duration of follow up.

188 Background: Androgen deprivation therapy (ADT) can cause considerable toxicity and may influence outcome. The study assessed the impact of testosterone recovery (TR) on survival after ADT and definitive radiotherapy in two independent cohorts. Methods: Two hundred and forty-four patients (high risk JHH cohort N=106, T1c-T3N0M0 [A], locally advanced OUH cohort N=138, T1c-T4N0-1M0 [B]) with adenocarcinoma of the prostate were included in this retrospective analysis. Short and long-term ADT was given (median 12 months A, 24 months B, respectively,) and along with conformal external beam radiation 76-80 Gy given to the prostate in cohort A, 74 Gy prescribed in cohort B and 46-50 Gy to the whole pelvis. Testosterone levels were measured at the end of ADT and at biochemical relapse. TR was defined as ≥ 9 nmol/L. Kaplan Meier plots were generated for overall survival (OS) and cause-specific survival (CSS) stratified by TR, in addition to patient characteristics median time to TR and FU were calculated. Results: The median age in the A cohort was 66.7 years and 64.7 years in the B group. FU was 6 years for A and 8 years in B. Patients in group A received median ADT of 12 months and 24 months in group B. The median time to TR was 1.6 yr in A and 2.5 yrs in B, respectively. Patients in group A stratified to TR showed no difference in overall survival (p=0.92)), on contrary, patients in group B showed improved overall survival depending on TR (Fig. 1, KM plot, 10 year OS 75.3% vs 59.9% p=0.034). CSS was seemed to trend towards improvement with TR for cohort A (p=0.19) and was improved in cohort B (p=0.022). The Univariate ADT length, age, and RT dose was associated with time to TR, but on multivariate analysis only longer ADT time (p = 0.03) was significantly associated with time to TR. Conclusions: TR was associated with improved OS in patients with unfavorable locally advanced disease a finding not seen in patients with high-risk disease.

High Sensitivity

Germ cell neoplasms in the group of benign and malignant tumors heterogeneous in morphological structure, clinical features and prognosis. A special characteristic of germ cell tumors is their high sensitivity to platinum-containing chemotherapy, which allows cure of up to 80–90% patients. However 20–25% of patients with a common type have overall survival rate of less than 50%. The aim of the study is to assess the survival rate of children with extracranial germ cell tumors and to identify adverse risk factors. Methods. The study includes 116 children with extracranial germ cell tumors treated from 2013 to September 2009. Treatment consisted of tumor resection and platinum based on platinum chemotherapy. Survival rate was assessed by the Kaplan-Mayer method. Prognostic factors are determined according to IGCCCG, MaGIC, MAKEI, RODO. Results. Overall and event free survival rates were 79±5% and 76±4%, respectively. The worst overall survival had patients with extragonadal tumors, advanced stages of a disease, high initial level of AFP (≥10 000 ng/ml), non-seminoma version of state treasury bills and extra pulmonary metastases. Conclusion. Survival rate in children with extracranial germ cell tumors depends on the prognostic factors. Statistically significant predictors of the poor prognosis were extragonadal localization of a tumor and the AFP level ≥10 000 ng/ml.

15572 Background: Previously, immunotherapy agents such as IFN were the only treatments available for mRCC. Sunitinib has demonstrated prolonged progression free survival in a phase III trial but overall survival benefit has yet to be determined and few patients (pts) with poor MSKCC prognostic profiles were included. Methods: The province-wide BC Cancer Agency Registry was cross-referenced to the central pharmacy database to identify all pts with the diagnosis of mRCC who were treated with IFN and/or sunitinib. Sunitinib became available after October 2005 under an expanded access program or as standard treatment. Three groups of pts were identified: Group A consisted of pts who received IFN alone between January 2003 to October 2005, Group B was all pts who progressed on first-line IFN after October 2005 and subsequently were treated with second-line sunitinib and Group C was all pts treated with first-line sunitinib. Baseline characteristics and overall survival were collected on all patients. Results: A total of 75 patients were identified with 36 patients in Group A, 23 patients in Group B, and 16 patients in Group C. Data are reported from the initiation of IFN in Group A and the initiation of sunitinib in Groups B and C. Median follow-up was 6.0 months in group A, 7.6 months in group B, and 6.2 months in group C. Median age of treatment initiation (62y vs. 60y vs. 62y), number of metastatic sites (>1 site in 63% vs. 61% vs. 56%), and Karnofsky performance status (79 vs. 86 vs. 81) were similar between groups A, B and C, respectively. The MSKCC prognostic profiles were favorable, intermediate and poor in 26%, 51% and 23% in group A, 17%, 65% and 17% in group B and 31%, 38% and 31% in group C, respectively. The estimated 6-month overall survival in groups A, B and C was 56%, 72% and 100%, respectively (log rank A vs C p=0.009; log rank B vs C p=0.042). Conclusion: With the limitations of retrospective analysis and preliminary follow-up, the introduction of sunitinib as standard treatment into the general population of patients with mRCC appears to be associated with a longer overall survival compared to patients treated with IFN alone. Population-based analysis on the impact of the introduction of sunitinib therapy is ongoing. No significant financial relationships to disclose.

Abstract OBJECTIVES To evaluate the potential role of emergency radiotherapy in intracranial germ cell tumors GCTs) patients with KPS ≤ 40. METHODS A total of 27 primary intracranial germ cell tumors (GCTs) patients with KPS ≤ 40 between Jan 2007 and Dec 2018 were retrospectively evaluated. The median age at initial diagnosis was 15 years (range, 528 years). Among those, 11 patients were germinoma and 16 patients were nonseminomatous germ-cell tumors (NGGCTs). There were 9 solitary pineal, 5 suprasellar, 3 basal ganglia and 10 multifocal and disseminated tumors. All patients received emergency radiotherapy (2 Gy/fx/d). Prior to radiotherapy, 11 patients were manifested with hydrocephalus, 10 with hypopituitarism and 5 with intracranial tumo apoplexy. RESULTS The average follow up time was 44.4 months. The 5 year progression free survival rate and overall survival rate were 29.6% and 33.3%. The median overall survival time was 38 months. In particular, the median intracranial hypertension symptoms relief time was 2 days. The median KPS following radiotherapy was 80 comparing to 30 prior to radiotherapy (P < 0.05). A significant improvement on KPS of 46.7±27.3 was observed in this study. CONCLUSION Emergency radiotherapy is implicated as a promising intervention for GCTs patients with elevated intracranial pressure (ICP). These advantages can be interpreted as direct cell killing effect and fast tumor shrinkage by ionizing radiation. However, to substantiate our findings, further investigations were highly warranted.

Abstract BACKGROUND Optimal strategy for treatment of relapsing intracranial malignant germ cell tumors remains ill-defined. Authors describe the French experience over a 25-year period. MATERIAL AND METHODS Relapsing patients were retrieved by their participation in the SFOP-TGM 90-92 or GCT 96 protocols or from National Childhood Solid Tumour Registry. RESULTS The cohort included Group A: documented germinomas (n=14), Group B: patients treated as germinomas without histopathological proof (n=5) and Group C: secreting germ cell tumours (n=25). Patients all received standard dose chemotherapy, and some high dose chemotherapy (VP16 Thiotepa with stem cell rescue) and/or various type of radiation. The 5 year EFS and OS post relapse are: 79%[47 to 93%] and 86% [54 to 96%] respectively in group A, 20% [1 to 58%] and 80% [20 to 97%] respectively in group B, 56% [35 to 73%] and 60% [38 to 76%] respectively in group C. Among 14 Group A patients, 7/12 receiving high dose versus 3/3 receiving standard dose chemotherapy, and 9/11 re-irradiated versus 1/3 not re-irradiated are CR2. Among 21 Group C patients. who had received radiation in first line, 10/15 receiving high dose versus 1/6 receiving standard dose chemotherapy, and 7/11 re-irradiated versus 4/10 not re-irradiated are CR2. CONCLUSION The outcome of relapsing germinoma is favourable and intensity of second line remains matter of debate. High dose chemotherapy with radiotherapy, when feasible, should remain the reference for treatment of a relapsed non germinoma, though more active treatments are warranted.

ObjectiveThe aim of this study was to analyze the oncological outcome of stage I malignant ovarian germ cell tumors patients included in the MITO-9 study to identify those who might be recommended routine surveillance alone after complete surgical staging.MethodsMITO-9 was a prospective observational study analyzing data collected between January 2013 and December 2019. Three groups were identified: group A included 13 patients stage IA dysgerminoma and IAG1 immature teratoma; group B included 29 patients with stage IB–C dysgerminomas, IA–C G2–G3 immature teratomas and stage IA mixed malignant ovarian germ cell tumors and yolk sac tumors; and group C included five patients (two patients with stage IC1 and one patient with stage IC2 yolk sac tumors and two patients with mixed-stage IC2 malignant ovarian germ cell tumors).ResultsA total of 47 patients with stage I conservatively treated malignant ovarian germ cell tumors were analyzed. Two patients in group B were excluded from the routine surveillance alone group due to positive surgical restaging. Therefore, a total of 45 patients were included in the study. Median follow-up was 46.2 months (range; 6–83). In total, 14 of 45 patients (31.1%) received chemotherapy, while 31 (68.9%%) underwent surveillance alone. One patient in group A, with stage IA dysgerminoma had a relapse, successfully managed with conservative surgery and chemotherapy. None of the patients in group B and C relapsed. All patients were alive at completion of the study. Overall, among 31 patients (68.9%) who underwent surveillance alone, only one patient relapsed but was treated successfully.ConclusionsOur data showed that close surveillance alone could be an alternative option to avoid adjuvant chemotherapy in properly staged IB–C dysgerminomas, IA–IC G2–G3 immature teratomas, and IA mixed malignant ovarian germ cell tumors with yolk sac tumor component.

2017 Background: Prognosis of glioblastoma (GBM) is very poor. Standard treatment includes surgical resection (SR), radiation (RT), concomitant and adjuvant chemotherapy with temozolomide (TMZ). Our objective is to assess the treatment efficacy, safety and survival in patients with newly-diagnosed GBM treated with RT, TMZ, and bevacizumab in the upfront management. Methods: From 2006–2008, 51 eligible patients (age >18, KPS >70) with newly-diagnosed GBM divided into two groups. Group A (n = 20) was treated with RT (60Gy) and concomitant TMZ (75mg/m2 daily for 42 days) with bevacizumab (10mg/kg every 2 weeks), 29 days following surgery, followed by up to six cycles of adjuvant TMZ (150mg/m2,daily x 7d, q28 with bevacizumab at 10mg/kg days 8 and 22 of each 28 day cycle. Group B (n = 31) received similar treatment without bevacizumab. Both groups were followed up until tumor progression (PFS). Recurrence was defined according to MacDonald Criteria. The end points were PFS, overall survival (OS) and toxicity. Results: Median bevacizumab infusions were 12 (4–32). Median follow-up was14 months for both groups. 6 months PFS survival in Group A was 77.5% and in Group B was 51.6%. Median PFS in Group A was 17 months compared to 7 months in Group B (p < 0.0001, HR = 0.26). Median OS has not been reached in Group A and was 17 months in Group B. One and 2 year OS were 83% and 57% in Group A compared to 72% and 6.5% in Group B (p = 0.02) ). Post-RT and temodar toxicities include thrombocytopenia (1 patient; Gr 3 and fatigue (3 patient;1 Gr 3), bevacizumab related toxicities with RT include leg ulcer with cellulites (1 patient; Gr 3) and pulmonary embolism with thrombocytopenia (1 patient; Gr 4), hypertension (2 patients; Gr 1), and asymptomatic blood products on MRI (2 patients). Conclusions: Bevacizumab has demonstrated efficacy, acceptable toxicity, improved PFS and OS in the upfront management of GBM. No significant financial relationships to disclose.

Mediastinal Teratoma

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.

PURPOSE: To evaluate therapeutic options for recurrent malignant sacrococcygeal germ cell tumors (GCT) following three-agent, cisplatinum-based, first-line chemotherapy and tumor resection. PATIENTS AND METHODS: Twenty-two patients were evaluated in 22 first-, 14 second-, five third-, and two fourth-relapse situations. One patient, who relapsed with pure teratoma, was excluded from the analysis of adjuvant treatment. RESULTS: Seventeen patients presented with an isolated local recurrence, two patients showed a distant relapse, and three patients suffered from a combined local and distant recurrence. Twelve patients achieved complete remission (CR) after surgery (n = 12) and adjuvant platinum chemotherapy (n = 10). Seven of these patients remain in continuous CR, and five patients relapsed. All patients who achieved only a partial remission developed a second relapse. Three of 14 patients could be cured after a second (or further) relapse. Altogether, 10 patients survived disease free, and 12 patients died as a result of tumor progression (n = 11) or therapy-related complications (n = 1). The completeness of salvage surgery and clinical remission status after first salvage treatment were the most important prognostic parameters. In addition, patients in first or second relapse with locally advanced or poorly responding tumors benefited from preoperative chemotherapy in combination with regional hyperthermia (RHT). In some patients after microscopically incomplete resection, irradiation at doses > 45 Gy contributed to a favorable outcome. CONCLUSION: The complete resection of the local recurrence represents the cornerstone of salvage treatment. Preoperative platinum-based chemotherapy, combined with RHT in some patients, facilitates complete tumor resection. Radiotherapy should be reserved for those patients with microscopically incomplete tumor resection. As the chance of cure decreases with further relapses, it is important to establish a stringent therapeutic strategy to avoid significant treatment delays and, most importantly, insufficient local therapy.
