Effect of Neoadjuvant Chemotherapy Plus Regional Hyperthermia on Long-term Outcomes Among Patients With Localized High-Risk Soft Tissue Sarcoma: The EORTC 62961-ESHO 95 Randomized Clinical Trial.

IMPORTANCE: Patients with soft tissue sarcoma are at risk for local recurrence and distant metastases despite optimal local treatment. Preoperative anthracycline plus ifosfamide chemotherapy improves outcome in common histological subtypes. OBJECTIVE: To analyze whether the previously reported improvement in local progression-free survival by adding regional hyperthermia to neoadjuvant chemotherapy translates into improved survival. DESIGN, SETTING, AND PARTICIPANTS: Open-label, phase 3 randomized clinical trial to evaluate the efficacy and toxic effects of neoadjuvant chemotherapy plus regional hyperthermia. Adult patients (age ≥18 years) with localized soft tissue sarcoma (tumor ≥5 cm, French Federation Nationale des Centers de Lutte Contre le Cancer [FNCLCC] grade 2 or 3, deep) were accrued across 9 centers (6, Germany; 1, Norway; 1, Austria; 1, United States) from July 1997 to November 2006. Follow-up ended December 2014. INTERVENTIONS: After stratification for tumor presentation and site, patients were randomly assigned to either neoadjuvant chemotherapy consisting of doxorubicin, ifosfamide, and etoposide alone, or combined with regional hyperthermia. MAIN OUTCOMES AND MEASURES: The primary end point was local progression-free survival. Secondary end points included treatment safety and survival, with survival defined from date of randomization to death due to disease or treatment. Patients lost to follow-up were censored at the date of their last follow-up. RESULTS: A total of 341 patients were randomized, and 329 (median [range] age, 51 [18-70] years; 147 women, 182 men) were eligible for the intention-to-treat analysis. By December 2014, 220 patients (67%; 95% CI, 62%-72%) had experienced disease relapse, and 188 (57%; 95% CI, 52%-62%) had died. Median follow-up was 11.3 years. Compared with neoadjuvant chemotherapy alone, adding regional hyperthermia improved local progression-free survival (hazard ratio [HR], 0.65; 95% CI, 0.49-0.86; P = .002). Patients randomized to chemotherapy plus hyperthermia had prolonged survival rates compared with those randomized to neoadjuvant chemotherapy alone (HR, 0.73; 95% CI, 0.54-0.98; P = .04) with 5-year survival of 62.7% (95% CI, 55.2%-70.1%) vs 51.3% (95% CI, 43.7%-59.0%), respectively, and 10-year survival of 52.6% (95% CI, 44.7%-60.6%) vs 42.7% (95% CI, 35.0%-50.4%). CONCLUSIONS AND RELEVANCE: Among patients with localized high-risk soft tissue sarcoma the addition of regional hyperthermia to neoadjuvant chemotherapy resulted in increased survival, as well as local progression-free survival. For patients who are candidates for neoadjuvant treatment, adding regional hyperthermia may be warranted. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00003052.

Dose adjustment of cisplatin, etoposide, and ifosfamide according to kidney function: a retrospective analysis and implications for medication safety.

Clearance of cisplatin, etoposide, and ifosfamide depends on kidney function and dosages should be adjusted in patients with renal impairment. However, there is still limited data on the adherence of physicians to dosing recommendations for these drugs in cancer patients with renal impairment. Three thousand four hundred forty-eight prescriptions to 369 patients, treated in the Comprehensive Cancer Center of a German university hospital, were retrospectively evaluated. The administered relative doses of cisplatin, etoposide, and ifosfamide were compared with relative doses recommended at the time of prescription according to the patients' creatinine clearance. Cisplatin is contraindicated according to two German summary of product characteristics (SmPC) in patients with a creatinine clearance < 60 mL/min. Nevertheless, 37 cisplatin prescriptions were made for this group of patients (i.e., 2.0% of all cisplatin prescriptions). According to one German SmPC (valid in the year of data analysis), etoposide dosage should be reduced in patients with a creatinine clearance from 15 to 50 mL/min, while it is contraindicated below 15 mL/min. Thirteen etoposide prescriptions were without dose reduction in patients with creatinine clearance from 15 to 50 mL/min (1.5% of all etoposide prescriptions); one patient received etoposide with creatinine clearance below 15 mL/min. In 8.9% of ifosfamide prescriptions, patients did not receive a reduced dose in spite of respective recommendations. Dosages of cisplatin, etoposide, and ifosfamide are not always adjusted as recommended in patients with renal impairment. Consistent international dosing recommendations (e.g., in SmPCs), preferentially included in clinical decision support systems, should be developed to tackle this problem.

Effective local control of advanced soft tissue sarcoma with neoadjuvant chemoradiotherapy and surgery: A single institutional experience.

PURPOSE: There is a sound theoretical basis but little clinical evidence substantiating the benefits of concurrent chemoradiotherapy with two-drug chemotherapy for locally advanced soft tissue sarcomas. Our five-year data on the feasibility and effectiveness of neoadjuvant chemoradiotherapy with systemically effective doses of adriamycin and ifosfamide combined is presented here. PATIENTS AND METHODS: Between 2000 and 2011, 53 patients with UICC (2010) stage I (n=1, 1.9%), II (n=12, 22.7%) or III (n=40, 75.5%) nonmetastatic soft tissue sarcoma received neoadjuvant chemoradiotherapy with ifosfamide (1.5 g/m(2)/day, d1-5, q28) and doxorubicin (50mg/m(2)/day, d3, q28) plus concurrent radiotherapy with a target dose of 50-64 Gy (median 60 Gy). The treatment of 34 patients (64.2%) was combined with hyperthermia. RESULTS: At five years, the local control rate was 89.9% (± 5.7%), distant metastasis-free survival 66.6% (± 7.6%), and survival 83.3% (± 6%). The R0 resection rate was 81.1%. Radiotherapy was completed as planned in all patients and chemotherapy in 42/53 (70.2%). Grades III (n=21, 29.6%) and IV (n=18, 34%) leukopenia was the main acute adverse event. All acute and chronic non-hematologic toxicities were moderate. CONCLUSION: Neoadjuvant chemoradiotherapy for soft tissue sarcoma is associated with good feasibility, manageable acute and late toxicities, and high local efficacy.

Adjuvant Ovarian Suppression, High-dose Chemotherapy and Immunotherapy for Premenopausal Patients with High-risk Breast Cancer.

BACKGROUND: Premenopausal patients with breast cancer and more than 10 positive axillary nodes (BC>10) have a poor prognosis: In these patients the best adjuvant therapy (CT) has not yet been established. PATIENTS AND METHODS: Forty-two BC>10 received, in sequence, the following adjuvant treatments: luteinizing hormone releasing hormone (LH-RH) analog for 5 years; anthracycline-based induction chemotherapy; radiation therapy; platinum-based high-dose CT, with autologous bone marrow transplantation; immunotherapy with interleukin 2 (IL2) and 13-cis retinoic acid (RA); anastrazole given 5 years to estrogen receptor-positive patients. Primary endpoints of the study were disease-free survival (DFS) and overall (OS) survival. A secondary endpoint was toxicity. RESULTS: The median age of patients was 41 years, and the mean number of positive axillary nodes was 14. Estrogen and progesterone receptors were positive in 57% and 29% of patients respectively, while 14% of patients had triple-negative disease. With a median follow-up of 120 months for patients remaining alive at the end of study, median DFS and OS, had not yet been reached. The 20-year DFS and OS rates were 63.8%, and 81.6%, respectively. One to two years after the end of the therapy, three patients had had four full-term pregnancies. CONCLUSION: Treatment with LH-RH analog, high-dose CT, peripheral blood progenitor cells and IL2 with RA for patients with BC>10 is feasible, has moderate toxicity, while preserving ovarian function, seems to improve the expected DFS and OS for these high-risk patients.

Highly effective reduced toxicity dose-intensive pilot protocol for non-metastatic limb osteogenic sarcoma (SCOS 89).

PURPOSE: Aggressive chemotherapy protocols for non-metastatic limb osteosarcoma have improved histological response without affecting prognosis. This study evaluated the toxicity and outcome of a dose-intensive, high-dose 3- to 5-drug pilot protocol, SCOS 89. METHODS: The cohort included 26 patients (14 male; ages 6.5-22 years) with non-metastatic limb osteosarcoma treated at a tertiary pediatric medical center between 1989 and 2013. Preoperatively, patients received two courses of once-weekly pulses of high-dose methotrexate (12-30 g/m(2)) for 2 weeks; doxorubicin (90 mg/m(2)) with dexrazoxane, combined with cisplatin (200 mg/m(2)), was added in week 3. Following methotrexate, 760 mg/m(2) of folinic acid was administered. Postoperative chemotherapy was continued to a total of 14 courses of methotrexate, doxorubicin (up to a total dose of 360 mg/m(2)), and cisplatin (up to a total dose of 560 mg/m(2)). If toxicity occurred or <90 % tumor necrosis, ifosfamide (12 g/m(2)) plus etoposide (500 mg/m(2)) was substituted for doxorubicin, cisplatin, or methotrexate. Toxicity and death rates were calculated. RESULTS: All patients underwent definitive limb salvage surgery. Six patients died of infection, recurrent disease, or secondary malignancy. Median follow-up was 100 months (range 2-290). Event-free and overall survival rates, respectively, were 88 and 96 % at 2 years, 80 and 87.6 % at 5 years, 80 and 78 % at 10 years. Eleven patients required ifosfamide/etoposide substitution. One patient had a transient decreased left ventricular ejection fraction. Two patients developed acute nephrotoxicity during therapy, but no neurotoxicity. Seven patients had hearing impairment. CONCLUSIONS: The SCOS 89 yields a high event-free survival rate with reduced nephro-/neuro-/cardiotoxicity in patients with non-metastatic limb osteosarcoma.

[Systemic therapy of soft tissue sarcomas].

Soft tissue sarcomas (STS) comprise a heterogeneous group of rare malignancies from mesenchymal tissues. The biology of STS causes high aggressiveness, poor prognosis due to early development of distant metastases and limited chemotherapeutic options due to tumor resistance. The paper considers the current principles of chemotherapy for early and metastatic disease. Results of own experience of advanced STS patients' treatment are presented and discussed.

Impact of perioperative chemotherapy on survival in patients with advanced primary urethral cancer: results of the international collaboration on primary urethral carcinoma.

BACKGROUND: To investigate the impact of perioperative chemo(radio)therapy in advanced primary urethral carcinoma (PUC). PATIENTS AND METHODS: A series of 124 patients (86 men, 38 women) were diagnosed with and underwent surgery for PUC in 10 referral centers between 1993 and 2012. Kaplan-Meier analysis with log-rank testing was used to investigate the impact of perioperative chemo(radio)therapy on overall survival (OS). The median follow-up was 21 months (mean: 32 months; interquartile range: 5-48). RESULTS: Neoadjuvant chemotherapy (NAC), neoadjuvant chemoradiotherapy (N-CRT) plus adjuvant chemotherapy (ACH), and ACH was delivered in 12 (31%), 6 (15%) and 21 (54%) of these patients, respectively. Receipt of NAC/N-CRT was associated with clinically node-positive disease (cN+; P = 0.033) and lower utilization of cystectomy at surgery (P = 0.015). The objective response rate to NAC and N-CRT was 25% and 33%, respectively. The 3-year OS for patients with objective response to neoadjuvant treatment (complete/partial response) was 100% and 58.3% for those with stable or progressive disease (P = 0.30). Of the 26 patients staged ≥cT3 and/or cN+ disease, 16 (62%) received perioperative chemo(radio)therapy and 10 upfront surgery without perioperative chemotherapy (38%). The 3-year OS for this locally advanced subset of patients (≥cT3 and/or cN+) who received NAC (N = 5), N-CRT (N = 3), surgery-only (N = 10) and surgery plus ACH (N = 8) was 100%, 100%, 50% and 20%, respectively (P = 0.016). Among these 26 patients, receipt of neoadjuvant treatment was significantly associated with improved 3-year relapse-free survival (RFS) (P = 0.022) and OS (P = 0.022). Proximal tumor location correlated with inferior 3-year RFS and OS (P = 0.056/0.005). CONCLUSION: In this series, patients who received NAC/N-CRT for cT3 and/or cN+ PUC appeared to demonstrate improved survival compared with those who underwent upfront surgery with or without ACH.

Concomitant trimodality therapy of re-irradiation, chemotherapy and regional hyperthermia for a pretreated inoperable sarcoma recurrence.

We hereby present a case of pre-treated unresectable sarcoma recurrence of the trunk which showed an excellent response to concomitant tri-modal therapy, consisting of re-irradiation, chemotherapy and regional hyperthermia even with a strong compromised re-irradiation dose. No significant toxicity of the combined therapy and fast achievement of the pain and neurological symptoms relief are reported. The case shows that concurrent tri-modality treatment can be considered as a therapeutic option for the management of pre-treated unresectable recurrence even in there-irradiation setting.

[Primary mediastinal germs cells tumors: a twenty years experience in a comprehensive cancer center]. / Tumeurs germinales primitives du médiastin : expérience de l'Institut de cancérologie de Lorraine sur une période de 20 ans (1990-2012).

UNLABELLED: The aim of this study is to report treatments results of patients with primary germ cell tumors (GCTs) of mediastinum. METHODS: A retrospective review was done of 19 consecutive patients with mediastinal GCTs treated in "Institut de cancérologie de Lorraine" between 1990 and 2012. RESULTS: A total of 19 patients were enrolled in this study. Three patients had pure seminoma and 16 patients had non-seminomatous germ cell tumors. All patients were treated with cisplatinum based chemotherapy at a dose of 33.48 mg/m(2)/week. At the end of chemotherapy, three patients (15.8%) had complete response and negative marker, seven of them (36.8%) had partial response and negative marker, five of them (26.32%) had partial response and positive marker, three of them (15.8%) had progressive disease (refractory disease) and one patient died because of the disease during treatment. The 1-year and 5-year overall survival rates were respectively 78 and 36% and the progression-free survival rate was 43%. When relapse occurred, this happened within a 13 month period. CONCLUSION: Our study confirmed the good management of mediastinal GCTs in our institute with similar results compared to literature.

A case of mediastinal embryonal carcinoma successfully treated by integrative therapy.

Mediastinal embryonal carcinoma is rare, and the life prognosis of this disease is assumed to be relatively short. We encountered a case of mediastinal embryonal carcinoma for which we could perform radical surgical resection. The patient was male, aged 16 years, and acutely aware of back pain. Because the pain increased during the same year, he visited a local doctor, and an expanding neoplastic lesion was detected in the right thoracic wall by computed tomography (CT). Then he was referred to our institution. Magnetic resonance imaging (MRI) showed a dumbbell type tumor (Eden type 3) at the Th7/8 level. Malignant disease was suspected, so the authors planned and performed CT-guided biopsy. The result showed that this tumor pathologically corresponded to malignant peripheral nerve sheath tumor (MPNST). Therefore, chemotherapy was considered the main treatment. After 2 courses of chemotherapy, the tumor size decreased dramatically. The authors thought that radical resection is possible if there is no intrathoracic tumor dissemination as a result of a favorable response to chemotherapy. We thus perfomed surgical resection after we confirmed by a thoracoscopic exploratory thoracotomy that there was no intrathoracic tumor dissemination. Pathological findings were consistent with an embryonal carcinoma. Both the cutting ends of the thoracic wall and the epidural lateral sides of the excised lesion were negative for tumor cells. There is no image finding from the MRI and PET-CT suggesting metastasis or recurrence in the MRI and PET-CT 18 months after surgical resection. Therefore, the long-term vital prognosis can be expected in this patient.

Midtreatment ¹8F-FDG PET/CT Scan for Early Response Assessment of SMILE Therapy in Natural Killer/T-Cell Lymphoma: A Prospective Study from a Single Center.

UNLABELLED: In a prospective study of newly diagnosed or relapsed histologically proven extranodal natural killer/T-cell lymphoma (ENKTL) patients, we aimed to determine the accuracy of midtreatment (18)F-FDG PET for response assessment using both visual and quantitative analyses. METHODS: Twenty-four patients (12 men, 12 women; median age, 50 y; age range, 16-83 y) were referred for pre-, mid- (after 2-3 cycles of SMILE [prednisolone, methotrexate, ifosfamide, L-asparaginase, etoposide] chemotherapy), and end-treatment PET/CT scans (n = 24, 24, and 17, respectively) using a standardized protocol. Sixty-five PET/CT scans were analyzed visually using the Deauville 5-point score (DS), and the lesion with the highest maximum standardized uptake value (SUV(max)) was recorded. Survival curves were obtained using Kaplan-Meier analysis and compared using the log rank test, followed by multivariate analysis using the Cox proportional hazards model to assess the independent effects of International Prognostic Index (IPI) score (0-1 vs. 2-5), stage (stage I/II vs. stage III/IV), sex, DS (1-3 vs. 4-5), SUV(max), and change in SUV(max) on overall survival (OS) and progression-free survival (PFS). The mean (±SD) follow-up period was 32 mo (±21 mo). RESULTS: For 2-y OS, the following parameters were predictive: IPI score (P = 0.047), DS at mid- and end-treatment (P < 0.001), and SUV(max) at mid- and end-treatment (P < 0.001 and 0.045, respectively). For 2-y PFS, the following parameters were predictive: sex (P = 0.006), stage (P = 0.034), IPI score (P = 0.038), DS at mid- and end-treatment (P < 0.001 and 0.001, respectively), and SUV(max) at midtreatment (P = 0.001). Multivariate analysis showed DS on mid- and end-treatment scans to be the only significant independent predictor of both OS (P = 0.004 and 0.018, respectively) and PFS (P = 0.004 and 0.014, respectively). The 2-y estimate for OS and PFS was 81% and 62%, respectively, in patients with a DS of 1-3, compared with 17% in patients with a DS of 4-5 (P < 0.001 and 0.001, respectively). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the midtreatment DS for prediction of OS and PFS were 63%, 94%, 83%, 83%, and 83%, respectively. CONCLUSION: Midtreatment PET/CT is a valuable tool for early treatment response assessment in extranodal natural killer/T-cell lymphoma patients.

Regional deep hyperthermia for salvage treatment of children and adolescents with refractory or recurrent non-testicular malignant germ-cell tumours: an open-label, non-randomised, single-institution, phase 2 study.

BACKGROUND: Although the survival of children and adolescents with malignant germ-cell tumours has improved greatly in recent years, the outcome remains poor for those with refractory or recurrent malignant germ-cell tumours. We aimed to determine whether objective tumour response could be achieved in patients with refractory or recurrent malignant germ-cell tumours with PEI-regional deep hyperthermia as salvage treatment. METHODS: Patients with refractory or recurrent non-testicular malignant germ-cell tumours after standard cisplatin-based chemotherapy were treated prospectively with PEI chemotherapy (cisplatin 40 mg/m(2), delivered intravenously on days 1 and 4; etoposide 100 mg/m(2), intravenously on days 1-4; and ifosfamide 1800 mg/m(2), intravenously on days 1-4) plus simultaneous 1-h regional deep hyperthermia (41-43°C) on days 1 and 4. Patients received three to four treatment courses at 21-day intervals until residual tumour resection was possible; they subsequently received one or two additional courses of PEI-regional deep hyperthermia. Local radiotherapy was given for incompletely resected tumours. Chemotherapy and hyperthermia toxic effects were assessed using WHO grading. The primary endpoint was the proportion of patients who had an objective response as assessed with Response Evaluation Criteria in Solid Tumors version 1.0 guidelines. Secondary endpoints were the event-free survival and overall survival after 5 years. This ongoing PEI-regional deep hyperthermia study (Hyper-PEI protocol) is registered at the German Cancer Society, number 50-2732. FINDINGS: 44 patients aged 7 months to 21 years (median 2 years 7 months) with refractory or recurrent malignant germ-cell tumours (nine patients with poor response, 23 patients with first relapse, 12 patients with multiple relapses) were included in this study. We identified 34 yolk sac tumours, eight embryonal carcinomas, one choriocarcinoma, and one dysgerminoma by histology analysis. Of the 35 patients who had sufficient clinical and radiographical data available for response assessment, 30 (86%) had an objective response to treatment (16 patients had complete remission and 14 had partial remission). 5-year event-free survival was 62% (95% CI 45-75), and 5-year overall survival was 72% (95% CI 55-83). The median follow-up of surviving patients was 82 months (range 9-195). WHO grade 3-4 neutropenia and thrombocytopenia occurred in all 181 chemotherapy cycles. Granulocytopenic fever, which required intercurrent hospital admission, was noted in 29 (66%) of 44 patients after 53 (29%) of 181 courses. Five patients experienced treatment-related grade-3 acute renal toxic effects. INTERPRETATION: A multimodal strategy integrating PEI-regional deep hyperthermia and tumour resection with or without radiation can successfully treat children and adolescents with refractory or recurrent malignant non-testicular germ-cell tumours. The long-term prognosis of patients with poor response or after first relapse was almost similar to those receiving first-line treatment. This strategy merits further investigation.

Effect of concurrent chemotherapy and hyperthermia on outcome of preoperative radiotherapy of high-risk soft tissue sarcomas.

BACKGROUND AND PURPOSE: As treatment results for high-risk soft tissue sarcoma are still disappointing, treatment intensification is warranted. We performed a retrospective analysis of multimodal preoperative treatment to evaluate the additional effect of concurrent chemotherapy and/or locoregional hyperthermia in comparison to radiotherapy alone. PATIENTS AND METHODS: Between 1999 and 2011, 28 patients were treated with neoadjuvant radiotherapy to a median 45 Gy for high-risk soft tissue sarcoma. All tumors were deep-seated and grade 2 or 3, 86% (n = 24) larger than 5 cm. Multimodal treatment (n = 12) consisted of ifosfamide (n = 7), locoregional hyperthermia (n = 3), or both modalities (n = 2) concurrent to radiotherapy. RESULTS: Prognostic factors (grade, size, histology, location) were balanced in the groups with and without concurrent multimodal treatment. There was a significant improvement of disease-specific survival (100% vs. 70% at 3 years, p = 0.03) with multimodal treatment. Distant metastases-free survival was influenced, but was not statistically significant. Local control and disease-free survival did not differ in the two groups. CONCLUSION: Our data suggest that multimodal treatment with ifosfamide and/or locoregional hyperthermia in combination with neoadjuvant radiotherapy might improve outcome in high-risk soft tissue sarcomas.

Analysis of prognostic factors in 333 Chinese patients with high-grade osteosarcoma treated by multidisciplinary combined therapy.

AIM: To investigate prognostic factors for long-term outcomes in Chinese patients with high-grade osteosarcoma of the extremities or trunk treated by multidisciplinary combined therapy. METHODS: In total, 333 consecutive patients with non-metastatic or primary metastatic high-grade osteosarcoma of the extremities or trunk were retrospectively reviewed to analyze the correlation between survival and sex, age, site, histological type, clinical stage, alkaline phosphatase (ALP) level, preoperative chemotherapy or not, response to preoperative chemotherapy, postoperative chemotherapy cycles and manner of surgery. The combined therapy included preoperative and postoperative chemotherapy as well as limb salvage surgery or amputation. RESULTS: The median survival time was 52 months for all 333 patients. Univariate analysis revealed that sex, ALP level, preoperative chemotherapy and cycle numbers of postoperative chemotherapy may influence the prognosis of high-grade osteosarcoma of the extremities or trunk. Multivariate analysis revealed that the female, a normal ALP level, preoperative chemotherapy with good response and ≥4 cycles of postoperative chemotherapy correlated with a better outcome. CONCLUSION: Preoperative chemotherapy is important in high-grade osteosarcoma treatment and a good response to it is an important marker of prognosis. It should be given with ≥ cycles of postoperative chemotherapy after surgery.

Importance of salvage therapy in the management of high-risk gestational trophoblastic neoplasia.

OBJECTIVE: To assess the value of secondary therapy in the management of high-risk gestational trophoblastic neoplasia (GTN) after failure of initial multiagent chemotherapy. STUDY DESIGN: Forty-nine women with high-risk GTN, including 29 who were treated primarily and 20 who were treated secondarily, completed treatment at the Brewer Trophoblastic Disease Center between 1986 and 2010. Initial chemotherapy consisted of etoposide, high-dose methotrexate with folinic acid, actinomycin D, cyclophosphamide and vincristine (EMA-CO) in 29 patients who were treated primarily and in 10 patients who had received single-agent chemotherapy before being treated at our center. Patients who had incomplete responses or developed resistance to EMA-CO or had previously received EMA-CO were treated with drug combinations employing etoposide and a platinum agent with methotrexate and actinomycin D (EMA-EP), bleomycin (BEP), ifosfamide (VIP, ICE) or paclitaxel (TP/TE). Adjuvant surgery and brain radiation were used in selected patients. Clinical response and survival as well as factors affecting outcomes were analyzed retrospectively. RESULTS: Twenty-eight (57%) of the 49 patients developed resistance to EMA-CO: 13 (45%) of 29 treated primarily and 15 (75%) of 20 treated secondarily. Of the 13 patients who failed primary treatment with EMA-CO, 10 (77%) had lasting complete responses to EMA-EP (4), BEP (3), VIP (1), ICE (1) or TP/TE (1). Of the 15 patients who failed EMA-CO used as secondary therapy, 13 (87%) had lasting complete responses to EMA-EP (5), BEP (6) or ICE (2). Brain irradiation was given to 4 patients who developed brain metastases during treatment, 3 of whom survived. Operative procedures were performed to remove resistant foci of disease in the lungs (9) or uterus (2) in 11 (39%) of the 28 patients, 9 (82%) of whom survived. Survival was significantly influenced by hCG level at the start of salvage therapy (p<0.001), number of metastatic sites (p <0.02) and metastases to sites other than the lung and vagina (p<0.05). CONCLUSION: Salvage therapy with platinum/etoposide-based drug regimens, often in conjunction with surgery and brain radiation, was successful in achieving cure in 82% of 28 high-risk GTN patients who failed initial multiagent chemotherapy and was ultimately responsible for survival in 53% of the 43 patients (88%) with high-risk GTN who were cured.

Clinical evaluation of neoadjuvant chemotherapy followed by radical surgery in the management of stage IB2-IIB cervical cancer.

OBJECTIVE: To evaluate clinical efficacy, toxicity, and survival outcomes of neoadjuvant chemotherapy (NACT) followed by radical surgery (RS) among patients with cervical cancer stage IB2-IIB. METHODS: In a retrospective clinical study at West China Second Hospital, Chengdu, data were analyzed from 414 patients who underwent NACT followed by radical surgery (NACT-RS) or RS alone between January 2008 and November 2009. RESULTS: The clinical response for NACT was 90%. Lymph node metastasis (25% versus 48%, P<0.05) and deep cervical stromal invasion more than 0.5, (68% versus 91%, P<0.05) were significantly lower among responders than among non-responders, respectively, in the NACT-RS group. The 2-year progression-free survival and 2-year overall survival were 93.0% and 95.5% in the NACT-RS group, and 94.5% and 97.1% in the RS group (P>0.05). Parametric infiltration (hazard ratio [HR], 7.668; P<0.05) and lymph node metastasis (HR, 7.714; P<0.05) were independent risk factors for all study patients. CONCLUSION: Compared with RS, NACT-RS did not show a significant advantage for patients with locally advanced cervical cancer. However, the data provide the rationale for assessing NACT-RS in a multicenter randomized clinical trial setting. NACT may be considered as an alternative treatment when radiotherapy is not available.

Type II radical hysterectomy and adjuvant therapy for pelvic lymph node metastasis with stage IB-IIB cervical carcinoma: a retrospective study of 288 patients.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate type II radical hysterectomy with or without adjuvant therapy as a treatment for patients with pelvic lymph node metastasis (PLNM) and stage IB-IIB cervical carcinoma. METHODS: A total of 288 patients with stage IB-IIB cervical carcinoma and confirmed PLNM who underwent a type II radical hysterectomy between 1995 and 2005 were retrospectively evaluated. RESULTS: The 5-year overall survival (OS) rate for this cohort was 65.6%, and independent prognostic factors identified for PLNM patients included a non-squamous cell histological subtype and parametrial involvement. Survival differences between patients that received or did not receive adjuvant treatment were also evaluated, and the 5-year OS and DFS rates for patients who did not receive adjuvant therapy (47 and 41.4%, respectively) were much lower than the rates for patients who did receive adjuvant therapies (67.7 and 59.4%, respectively). However, these differences were not statistically significant (OS, P = 0.057; DFS, P = 0.080). CONCLUSIONS: Type II radical hysterectomy, in combination with adjuvant therapies, is an efficient treatment for PLNM patients with stage IB-IIB cervical cancer.

Neo-adjuvant chemotherapy alone or with regional hyperthermia for localised high-risk soft-tissue sarcoma: a randomised phase 3 multicentre study.

BACKGROUND: The optimum treatment for high-risk soft-tissue sarcoma (STS) in adults is unclear. Regional hyperthermia concentrates the action of chemotherapy within the heated tumour region. Phase 2 studies have shown that chemotherapy with regional hyperthermia improves local control compared with chemotherapy alone. We designed a parallel-group randomised controlled trial to assess the safety and efficacy of regional hyperthermia with chemotherapy. METHODS: Patients were recruited to the trial between July 21, 1997, and November 30, 2006, at nine centres in Europe and North America. Patients with localised high-risk STS (> or = 5 cm, Fédération Nationale des Centres de Lutte Contre le Cancer [FNCLCC] grade 2 or 3, deep to the fascia) were randomly assigned to receive either neo-adjuvant chemotherapy consisting of etoposide, ifosfamide, and doxorubicin (EIA) alone, or combined with regional hyperthermia (EIA plus regional hyperthermia) in addition to local therapy. Local progression-free survival (LPFS) was the primary endpoint. Efficacy analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT 00003052. FINDINGS: 341 patients were enrolled, with 169 randomly assigned to EIA plus regional hyperthermia and 172 to EIA alone. All patients were included in the analysis of the primary endpoint, and 332 patients who received at least one cycle of chemotherapy were included in the safety analysis. After a median follow-up of 34 months (IQR 20-67), 132 patients had local progression (56 EIA plus regional hyperthermia vs 76 EIA). Patients were more likely to experience local progression or death in the EIA-alone group compared with the EIA plus regional hyperthermia group (relative hazard [RH] 0.58, 95% CI 0.41-0.83; p=0.003), with an absolute difference in LPFS at 2 years of 15% (95% CI 6-26; 76% EIA plus regional hyperthermia vs 61% EIA). For disease-free survival the relative hazard was 0.70 (95% CI 0.54-0.92, p=0.011) for EIA plus regional hyperthermia compared with EIA alone. The treatment response rate in the group that received regional hyperthermia was 28.8%, compared with 12.7% in the group who received chemotherapy alone (p=0.002). In a pre-specified per-protocol analysis of patients who completed EIA plus regional hyperthermia induction therapy compared with those who completed EIA alone, overall survival was better in the combined therapy group (HR 0.66, 95% CI 0.45-0.98, p=0.038). Leucopenia (grade 3 or 4) was more frequent in the EIA plus regional hyperthermia group compared with the EIA-alone group (128 of 165 vs 106 of 167, p=0.005). Hyperthermia-related adverse events were pain, bolus pressure, and skin burn, which were mild to moderate in 66 (40.5%), 43 (26.4%), and 29 patients (17.8%), and severe in seven (4.3%), eight (4.9%), and one patient (0.6%), respectively. Two deaths were attributable to treatment in the combined treatment group, and one death was attributable to treatment in the EIA-alone group. INTERPRETATION: To our knowledge, this is the first randomised phase 3 trial to show that regional hyperthermia increases the benefit of chemotherapy. Adding regional hyperthermia to chemotherapy is a new effective treatment strategy for patients with high-risk STS, including STS with an abdominal or retroperitoneal location.

Radiological assessment following thermoradiation therapy for primary pleural synovial sarcoma: case report.

Primary pleural synovial sarcoma is a rare disease with poor outcomes. Although hyperthermia therapy as part of a combined treatment regimen can offer improved local tumor control, only two reports of hyperthermia therapy for synovial sarcoma have appeared in the literature, and these sarcomas were not of pleuropulmonary origin. This report of an advanced inoperable primary pleural synovial sarcoma is the first to address the use of hyperthermia therapy in combination with chemoradiotherapy for this disease, together with radiological assessment following that therapy. Computed tomography performed after thermoradiation showed a decrease in tumor size and a characteristic unenhanced low-density area in the tumor suggesting that tumor necrosis resulted from the therapy. These image findings were helpful in assessing the tumor response to thermoradiation. We believe that hyperthermia therapy combined with chemoradiotherapy should be regarded as an option for advanced primary pleural synovial sarcoma. This would give computed tomography important role in evaluating this approach.

Alveolar rhabdomyosarcoma of the extremity and nodal metastasis: Is the in-transit lymphatic system at risk?

Alveolar rhabdomyosarcoma (RMS) of the extremity is not infrequently associated with regional node metastasis. Knowledge of lymphatic drainage of extremity RMSs is important to determine radiotherapy fields. In this report we describe two patients with alveolar RMS of the lower extremity with inguinal metastasis at presentation. Both the distal lower extremity and inguinal region received local therapy consisting of surgery and postoperative radiotherapy. Both patients later developed in-transit lymphatic metastasis outside of the irradiated field. The in-transit lymphatics can be a site of failure in children with alveolar RMS of the extremity and nodal involvement.
