RESUMO

Background: Therapeutic options for patients with chemoresistant germ cell tumors (GCTs) are limited. Pazopanib is a selective tyrosine kinase inhibitor with distinct antiangiogenic activity. We aimed to evaluate pazopanib activity in patients with refractory GCT. Patients and methods: In the open-label, single-arm, phase 2 Pazotest study (NCT01743482), patient eligibility included failure of ≥2 platinum-based regimens, and allowed prior high-dose chemotherapy administration. Patients were given pazopanib 800 mg/day until disease progression (PD) or onset of unacceptable toxicity. Measurements of serum tumor markers (STM), computed tomography and FDG-PET were carried out at baseline, after 4 weeks of pazopanib treatment, and every 8 weeks thereafter. PD was defined as increasing levels of STM, increasing size of non-teratomatous masses, or appearance of new lesions. The study primary endpoint was progression-free survival (PFS, H0: 3-month PFS ≤ 10%, H1: ≥25%, α = 5%, ß = 20%). Results: Forty-three patients were enrolled from May 2013 to July 2016. The number of prior chemotherapy regimens was: 2 (11.6%), 3 (51.2%), >3 (37.2%). Grade 3 adverse events were observed in six patients (13.9%). Overall, 70.3% of patients had reduced levels of STM after 4 weeks. There were 2 partial responses (4.7%), 19 cases of stable disease, and 16 cases of PD (6 not evaluable by RECIST). The median follow-up duration was 29.6 months. The 3-month PFS probability was 12.8% [95% confidence interval (CI): 5.7%-28.9%]. The 24-month OS probability was 14.2% (95% CI: 6.0%-33.7%). In patients with a >50% decline in STM, the 24-month OS probability was 24.1% (95% CI: 8.3%-69.6%). The small sample size was the major limitation. Conclusions: Despite pazopanib showed potent but short-lived activity in refractory GCT, long-term survival was obtained in a proportion of treated patients. According to the kinetics of pazopanib activity, this drug may be investigated in less pre-treated patients as an optimal bridging therapy preceding and/or combined with salvage chemotherapy.

RESUMO

BACKGROUND: Outcomes of radiotherapy (RT) compared with chemotherapy (CT) remain poorly defined for clinical stage (CS) IIA and IIB seminoma. We aimed to evaluate the current role of the two treatment modalities in this setting of testicular seminoma. PATIENTS AND METHODS: A systematic review and meta-analysis (MA) was carried out to identify all evaluable studies. Search was limited to studies published after 1990 and included the Medline, Embase databases, and abstracts from ASCO (GU), ESMO, AUA, and ASTRO meetings up to April 2014. Sensitivity analyses were applied including the following: CSIIA and CSIIB, paraortic + iliac RT only in both stages, RT dose (≥30 versus <30 Gy), and PEB/EP regimens only. RESULTS: Thirteen studies have been selected for MA on relapse outcome. No randomized trials compared RT and CT. There were 4 prospective and 9 retrospective studies, with a total of 607 patients receiving RT and 283 patients CT. The pooled relapse rate (RR) was similar between the RT [0.11, 95% confidence interval (CI) 0.08-0.14, P for heterogeneity = 0.096, I(2) = 38%] and CT groups (0.08, 95% CI 0.01-0.15, P for heterogeneity <0.001, I(2) = 82.5%). However, in the sensitivity analysis, the pooled RR for RT in CSIIB was 0.12 (95% CI 0.06-0.17) while it was 0.05 (95% CI 0-0.11) for CT. Long-term side-effects and incidence of second cancers were more frequently reported following RT. The overall incidence of nontesticular second malignancies was 0.04 (95% CI 0.01-0.02) in the RT group and 0.02 (95% CI 0.003-0.04) in the CT group. CONCLUSIONS: Although RT and CT appeared to be equal options in CSIIA and IIB seminoma, a trend in favor of CT for a lower incidence of side-effects and RR in CSIIB was found. This evidence is limited by the retrospective quality of studies and their small sample size.

RESUMO

BACKGROUND: In the late 1990s, the use of high-dose chemotherapy (HDCT) and stem-cell rescue held promise for patients with advanced and poor prognosis germ-cell tumors (GCT). We started a randomized phase II trial to assess the efficacy of sequential HDCT compared with cisplatin, etoposide, and bleomycin (PEB). PATIENTS AND METHODS: Patients were randomly assigned to receive four cycles of PEB every 3 weeks or two cycles of PEB followed by a high-dose sequence (HDS) comprising HD-cyclophosphamide (7.0 g/m(2)), 2 courses of cisplatin and HD-etoposide (2.4 g/m(2)) with stem-cell support, and a single course of HD-carboplatin [area under the curve (AUC) 27 mg/ml × min] with autologous stem-cell transplant. Postchemotherapy surgery was planned on responding residual disease in both arms. The primary end point was progression-free survival (PFS). The study was designed to detect a 30% improvement of 5-year PFS (from 40% to 70%), with 80% power and two-sided α at 5%. RESULTS: From December 1996 to March 2007, 85 patients were randomized: 43 in PEB and 42 in HDS arm. Median follow-up was 114.2 months [interquartile range (IQR): 87.7-165.8]. Complete or partial response with normal markers (PRm-) were obtained in 28 (65.1%) and 29 (69.1%) patients, respectively. Five-year PFS was 55.8% [95% confidence interval (CI) 42.8-72.8] and 54.8% (95% CI 41.6%-72.1%) in PEB and HDS arm, respectively (log-rank test P = 0.726). Five-year overall survival was 62.8% (95% CI 49.9-79.0) and 59.3% (95% CI 46.1-76.3). One toxic death (PEB arm) was recorded. CONCLUSIONS: The study failed to meet the primary end point. Furthermore, survival estimates of conventional-dose chemotherapy higher than expected should be accounted for and will likely limit further improvements in the first-line setting.

RESUMO

BACKGROUND: Pazopanib achieved the end point of clinical activity in pretreated patients with urothelial cancer in a single-group, phase 2 trial. The objective was to identify biological predictors of clinical benefit to pazopanib in these patients. METHODS: EDTA blood samples were collected at baseline (T0) and after 4 weeks (T1) of treatment, together with radiological imaging in all 41 patients to analyse plasma circulating angiogenic factor levels by multiplex ELISA plates. Changes from T0 to T1 in marker levels were matched with response with the covariance analysis. Univariable and multivariable analyses evaluated the association with overall survival (OS), adjusted for prespecified clinical variables. Net reclassification improvement (NRI) tested the performance of the recognised Cox model. RESULTS: Increasing IL8(T1) level associated with lower response probability at covariance analysis (P=0.010). Both IL8(T0) (P=0.019) and IL8(T1) (P=0.004) associated with OS and the prognostic model, including clinical variables and IL8(T1) best-predicted OS after backward selection. The NRI for this model was 39%.When analysed as a time-varying covariate, IL8(T1) level<80 pg ml(-1) portended significantly greater response (∼80%) and 6-month OS (∼60%) probability than level ≥ 80. CONCLUSION: IL8-level changes during pazopanib allowed for a prognostic improvement and were associated with response probability.

RESUMO

Despite a compelling preclinical rationale for the use of anti-angiogenic drugs in urothelial cancer (UC), short-living responses have been observed in clinical trials. PF-03446962 is a novel monoclonal antibody against Activin Receptor-Like Kinase-1 (ALK1), a type I subclass of the TGFß receptor, with dose-dependent anti-angiogenic activity. An open label, single-group, phase 2 trial of PF-03446962 was conducted in salvage setting. Patients failing at least one chemotherapy regimen were eligible. Design provided PF-03446962 10 mg/Kg intravenously fortnightly until disease progression (PD) or unacceptable toxicity. Two-month progression-free survival (PFS) was the primary endpoint. The trial was registered with ClinicalTrials.gov, number NCT01620970. Fourteen patients were enrolled from October 2012 to July 2013. Median age was 64 years (interquartile range [IQR]: 58.2-69.5), 9 patients had a Bellmunt score of 1-2, median number of prior drugs was 3. One stable disease and 13 PD were recorded and the study met the futility stopping rule of interim analysis. Median PFS was 1.8 months (95 %CI, 1.4-2.0). After a median follow up of 7.4 months (IQR 4.5-10.9), 8 patients are alive. Median overall survival (OS) was 8 months (95 %CI, 2.9-not estimable). Most common toxicities were thrombocytopenia (G1-2 in 5 cases, persistent G3 in one, with 3 dose delays and 1 dose interruption), fatigue and abdominal pain (G1-2 in 4 cases each). Impairment of quality of life (ESAS score) was observed as well as an increase from baseline to +2 month median levels of vascular endothelial growth factor (VEGF) and interleukin-8. PF-03446962 had no activity as single drug in refractory UC and we do not recommend further investigation outside of the combination with agents targeting the VEGF receptor axis.

RESUMO

BACKGROUND: Since 1985, we introduced a modified combination of etoposide, ifosfamide, and cisplatin (PEI) as second-line therapy of adult male germ cell tumors with the aim to reduce toxic effect while maintaining efficacy over the original regimen. PATIENTS AND METHODS: Patients received four cycles of ifosfamide at 2.5 g/m(2) on days 1-2, etoposide, and cisplatin at 100 and 33 mg/m(2), respectively, on days 3-5 every 21 days, followed by surgery. Results were stratified according to the International Germ Cell Consensus Classification Group-2 (IGCCCG-2). RESULTS: From February 1985 to January 2012, 189 patients were treated. 72.6% were IGCCCG-2 intermediate-to-very high risk. Thirty-five patients (18.5%) had a complete response, 67 (35.4%) a marker normalization (PRm-). Median follow-up was 122.1 months (inter-quartile range [IQR]: 71.4-232.0). Two-year progression-free and 5-year overall survival were 34.3% [95% confidence interval (CI) 28.1% to 41.9%] and 42.1% (95% CI 35.3% to 50.2%), respectively. Survival estimates compared favorably with those obtained by conventional dose chemotherapy (CDCT) regimens in each prognostic category. 70.4% of grade 3-4 neutropenia (25.5% febrile neutropenia), 48.1% thrombocytopenia, 21.2% anemia, 3.2% neurotoxic effect, and no severe renal toxic effect were recorded. CONCLUSION: Dose-modified Italian PEI should be considered as an appropriate benchmark for CDCT in the first salvage setting.

RESUMO

PURPOSE: We analysed our experience with computed tomography (CT)-guided percutaneous cryoablation (PCA) in patients who were not surgical candidates or refused surgery for small to medium-sized renal masses. MATERIALS AND METHODS: Two freezing cycles were applied and separated by a passive warming cycle using 1.7- and 2.4-mm cryoprobes under either general anaesthesia or sedation based on patient positioning and respiratory status. Postoperative monitoring included haematological and biochemistry evaluation and CT scan 24 h after PCA. Follow-up consisted of a multislice CT scan at 1 month and every 3 months in the first year then every 6 months thereafter. RESULTS: Thirty-seven patients (38 lesions) underwent 40 PCA procedures; 5/37 (13.5%) had a solitary kidney. Median mass size was 35 (range 12-70) mm. No complications occurred during the procedure. Clavien grade ≥2 anaemia occurred in two patients (5.4 %): one patient required 1 U of packed red blood cells; the other required an arterial embolisation. Serum creatinine did not increase in any case. Two patients showed persisting or recurrent disease at 1 and 9 months, respectively, and both could be re-treated with PCA. All other patients showed a hypodense mass 3 months after PCA, with no contrast enhancement. Subsequent examinations showed that lesion sizes decreased and CT densitometry remained stable or increased minimally, also with no contrast enhancement. CONCLUSIONS: PCA proved relatively easy and safe and could be considered an effective alternative for patients who are not surgical candidates or refuse surgery, as well as in patients with medium-sized lesions.

RESUMO

BACKGROUND: The purpose of this study was to validate a prognostic index [surgical complete response 1 (sCR1)] in patients with postchemotherapy viable nonseminomatous germ-cell tumors (NSGCT). PATIENTS AND METHODS: Data and specimens from 61 patients with normalized tumor markers and postchemotherapy viable nonteratomatous NSGCT treated in 13 institutions were collected. RESULTS: With a median follow-up of 5.4 years, the 5-year progression-free survival (PFS) rate was 65%; the 5-year overall survival (OS) rate was 72%. Favorable PFS was predicted by a complete resection, <10% of viable malignant cells, and a good International Germ Cell Consensus Classification group at presentation. Patients were assigned to one of three risk groups defined in sCR1: no risk factor (good risk), one risk factor (intermediate risk) and two to three risk factors (poor risk group). The 5-year PFS rate was 92%, 78%, and 42%, respectively (P = 0.002) (as compared with 90%, 76%, and 41% in the original sCR1 study). The 5-year OS rate was 90%, 86%, and 52%, respectively (P = 0.009) (as compared with 100%, 83%, and 51% in the original sCR1 study). Postoperative chemotherapy did not appear to improve OS compared with surveillance and treatment only at relapse. CONCLUSION: In patients with postchemotherapy viable NSGCT, a complete resection of residual masses should be rigorously pursued. These data validate the sCR1 prognostic index. Given their excellent outcome, patients in the favorable group may not require postoperative chemotherapy.

RESUMO

PURPOSE: Besides tumors that are diagnostic of AIDS, such as non-Hodgkin's lymphoma, Kaposi's sarcoma, and invasive carcinoma of the cervix, other tumors have been described in the human immunodeficiency virus (HIV) setting. Some case reports on testicular cancer in HIV-infected patients have appeared in the literature. We present a retrospective study on 26 cases of testicular germ cell tumors (TGCTs) observed within the Italian Cooperative Group on AIDS and Tumors (GICAT) between November 1986 and September 1994. PATIENTS AND METHODS: Twenty-six patients with TGCT and HIV-infection from the GICAT were retrospectively analyzed. RESULTS: Fourteen patients had seminoma and 12 had nonseminoma. Four patients underwent only orchidectomy, one patient received only chemotherapy, nine patients were treated with postsurgical chemotherapy, 10 patients (38%) received postsurgical radiotherapy, one patient received postsurgical chemotherapy plus radiotherapy, and one patient was lost for follow-up evaluation immediately after diagnosis. The complete response (CR) rate was 95%. Relapse occurred in 32% of patients. The median follow-up time was 33 months. The mortality rate was 37%. Causes of death were neoplasia in three of nine patients, AIDS in five of nine patients, and fortuitous event in one of nine patients. The overall 3-year survival rate was 65%, and the 3-year disease-free survival rate was 65%. Severe hematologic toxicity was observed in seven of 15 patients. CONCLUSION: HIV-infected patients with testicular cancer should be offered standard oncologic therapy, irrespective of their HIV status, since the majority can be cured of their tumor and have a good quality of life. Use of concomitant prophylaxis for opportunistic infections is recommended.

RESUMO

Sixty-two consecutive patients with clinical stage I nonseminomatous testicular cancer were entered into a prospective study to receive no treatment after orchiectomy until clinical evidence of recurrent disease. Of 59 evaluable cases, 41 (69.5%) remained continuously disease free for a median duration of 30 months (range, 18 to 46 months), and evidence of metastatic disease developed in 18 patients (30.5%) from 2 to 36 months after orchiectomy. The median disease-free interval for relapsing patients was 6 months. Retroperitoneal metastases developed in ten patients; seven patients had pulmonary metastases, and one patient had progressive elevation of the serum alpha-fetoprotein level. Relapses were significantly more frequent in patients with either embryonal carcinoma, infiltrating testicular cancer (pT greater than 1), peritumoral vascular invasion, or in those who underwent transscrotal biopsy. One patient with relapse refused salvage therapy and died. The remaining 17 patients have been rendered disease free with cisplatin combination chemotherapy and/or surgery. However, two patients showed further recurrence, with one in the lung and the other one also in the retroperitoneal nodes. In our opinion, surveillance following orchiectomy will provide useful information in clinical stage I nonseminomatous testicular cancer, but it is a difficult study. For the time being, it should be restricted to specialized centers only. In the meanwhile, retroperitoneal lymphadenectomy remains the standard treatment.

RESUMO

PURPOSE: To assess the value of postsurgery chemotherapy in patients with disseminated nonseminomatous germ-cell tumors (NSGCTs) and viable residual disease after first-line cisplatin-based chemotherapy. PATIENTS AND METHODS: The outcome of 238 patients was reviewed. Tumor markers had normalized in all patients before resection. A multivariate analysis of survival was performed on 146 patients. RESULTS: The 5-year progression-free survival (PFS) rate was 64% and the 5-year overall survival (OS) rate was 73%. Three factors were independently associated with both PFS and OS: complete resection (P <.001), < 10% of viable malignant cells (P =.001), and a good International Germ Cell Consensus Classification (IGCCC) group (P =.01). Patients were assigned to one of three risk groups: those with no risk factors (favorable group), those with one risk factor (intermediate group), and those with two or three risk factors (poor-risk group). The 5-year OS rate was 100%, 83%, and 51%, respectively (P <.001). The 5-year PFS rate was 69% (95% confidence interval [CI], 62% to 76%) and 52% (95% CI, 40% to 64%) in postoperative chemotherapy recipients and nonrecipients, respectively (P <.001). No significant difference was detected in 5-year OS rates. After adjustment on the three prognostic factors, postoperative chemotherapy was associated with a significantly better PFS (P <.001) but not with better OS. Patients in the favorable risk group had a 100% 5-year OS, with or without postoperative chemotherapy. Postoperative chemotherapy appeared beneficial in both PFS (P <.001) and OS (P =.02) in the intermediate-risk group but was not statistically beneficial in the poor-risk group. CONCLUSION: A complete resection may be more critical than recourse to postoperative chemotherapy in the setting of postchemotherapy viable malignant NSGCT. Immediate postoperative chemotherapy or surveillance alone with chemotherapy at relapse may be reasonable options depending on the completeness of resection, IGCCC group, and percent of viable cells. Validation is necessary.

RESUMO

This schedule has shown an interesting activity with nearly 40% of the patients achieving CR. Moreover 4 patients experienced an inversion rate (CR with ABMT when they never achieved this status before). In terms of toxicity, this schedule seems feasible with 2/28 toxic deaths, which is in the lower part of the range of major solid tumors ABMT programs. But even if the rationale is proper, a better patients' selection is required. The CCR (continuous Complete Remission) rate is overimposable to other main studies previously published, but all our CCR were obtained in responding patients (Sensitive Relapses or unresectable PR). We may suggest that earlier transplantation is advisable when less tumor bulky is present and less clonal eterogeneity. The exact maximum tolerated dose of Carboplatin/VP 16/Ifosfamide programs has not yet clearly pointed out. The lack of major life-threatening episodes and neuro/nephrotoxicity may allow us to explore higher Carboplatin doses. Anyway the ultimate answer to the utility of ABMT trials must come from a randomized study in responding patients.

RESUMO

In this paper an Italian cooperative trial investigates the role of a high-dose regimen with carboplatin, etoposide and ifosfamide in germ cell tumours. Twenty-eight patients underwent one or two transplants. Seventeen with progressive disease. Nine in sensitive relapse and two with stable disease after salvage therapy. Toxicity was generally moderate: two deaths occurred at day 15 from ABMT (one from VOD and one from tumour growth). Five patients are alive and disease free at least 10 months follow-up. In highly pre-treated patients this high-dose combination seems to give an option of cure for relapsed patients. Early transplantation is suggested.

RESUMO

Twenty-eight patients with metastatic renal cell carcinoma entered a multicentric prospective study to evaluate the response to high-dose medroxyprogesterone acetate (MPA) and testosterone in MPA failures in relation to sex steroid receptors. No objective remission was seen in the 24 evaluable patients, and only disease stabilizations of short duration were achieved in one-third of treated patients. Stabilizations achieved with second line testosterone were all seen in patients unresponsive to MPA. Receptor studies demonstrated that estrogen, progesterone, or androgen receptors were found in low concentrations and in only 6 of 23 tumors (26%) and 13 normal tissue samples (56%). Surprisingly, no disease stabilization was achieved in patients positive for receptors. It can be concluded that the occasional objective responses to hormone therapy reported in the literature may have been due to some cytotoxic effect of hormone therapy rather than to a true hormonal mechanism.

RESUMO

From January 1987 to December 1990, 14 consecutive patients with resectable metastases from renal cell carcinoma, underwent 3 cycles of preoperative alpha-2a Interferon (INF), 18 MUI s.c. 3 times a week, and Vinblastine (VLB), 0.15 mg/kg on day 1, every 21, days. Out of the 13 patients who completed the treatment, 4 (30.7%) achieved a clinical response (1 CR and 3 PR). Nine (69.3%) patients were submitted to surgery: all, including the CRer, had residual cancer and only 4 were radically resected. The latter were further submitted to 3 INF and VLB cycles: 2 relapsed after 7 and respectively 30 months, whilst 2 (15.4%) are alive disease-free at 12 and 52 months respectively.

RESUMO

Twenty-eight consecutive patients submitted to radical nephrectomy for Robson's stage II-III renal cell carcinoma underwent adjuvant recombinant a-2b interferon, 5 MUI s.c. 3 times a week, for 6 consecutive months. Home-feasibility of this therapy resulted easy. The most frequent acute (flu-like syndrome) and late (myalgia, fatigue, anorexia) side effects did not affect normal daily life of patients. Eight (28.5%) patients had WHO grade < or = 2 biochemical and hematological toxicity, that normalized after a reduction or a temporarily suspension of therapy. Twenty-seven patients were evaluable for response. Out of these, 7 (26%) relapsed after a 16 months median follow-up.

RESUMO

At INT of Milan between 1964 and 1990, 204 consecutive native patients suffering from penile cancer have been treated. 101 (59%) patients out of 171 with invasive cancer (23 affected with Tis were excluded) have been classified T1N0M0. 74 patients have been treated with penis conserving methods, such as circumcision, radiotherapy, laser excision and primary chemotherapy + conserving surgery. Overall local failure and/or nodal relapses occurred in 27% (20/74). Relapses are significantly related with grading but there isn't any relationship with macroscopical aspect or size of the tumor. The conservative treatment had been possible in 80% of patients. In our experience T1N0 clinical stage conservative therapy does not worsen the prognosis.

RESUMO

Germ-cell tumors of the testis (GCTT) are rare, but have a high social impact. In fact they represent no more than 1% of male tumors (about 700 new cases per year in Italy), but electively occur in young patients, 20 to 40 years old, during their fully mature social and working life. More than 80% of patients are cured and return to a normal social, sexual, and working life. Improvements achieved both in diagnosis, with the use of scans (CT, MRI, US and recently PET) and of serum tumor markers alpha-fetoprotein (AFP), beta-fraction of human chorionic gonadotropin (b-HCG) and lactate dehydrogenase (LDH), and mainly in treatment, through the amelioration of radiotherapy and surgical techniques and, especially, with the introduction of Cisplatin, Etoposide and Ifosfamide in chemotherapic regimens, have made germ-cell tumor a model of "curable disease". Retroperitoneal lymph node dissection (RPLND) has indications in patients with clinical stage I (CS1) as well as in advanced disease, where it is integrated in the multimodality treatment. Anatomical studies, as well as a long-term experience, have gradually but consistently modified the surgical techniques of RPLND. Currently, "nerve sparing" RPLND represents a safe management of CS1 nonseminomatous germ cell testicular tumor with minimal morbidity and excellent outcomes. Nonetheless, surveillance and adjuvant chemotherapy are as effective as RPLND, but, in our opinion, associated with some discomforts for the patients. Laparoscopic retroperitoneal lymph node dissection (Lap-RPLND) is gaining popularity as a minimally invasive staging procedure for clinical stage I nonseminomatous testicular carcinoma, but its therapeutic role is still under investigation.
