Background: The ACCORD 16 phase II trial aimed to evaluate the objective response rate after combination of conventional chemoradiotherapy (CRT) and cetuximab in locally advanced anal canal carcinoma (LAACC).Patients and methods: Immunocompetent patients with histologically confirmed LAACC received CRT [45 gray (Gy)] in 25 fractions over 5 weeks, fluorouracil and cisplatin during weeks 1 and 5), in combination with weekly dose of cetuximab (250 mg/m2 with a loading dose of 400 mg/m2 1 week before irradiation), and a standard dose boost (20 Gy). The trial was originally designed to include 81 patients to detect a 15% of objective response increase with the new combination in comparison with CRT. Results: The trial was prematurely stopped after the declaration of 15 serious adverse events (SAEs) in 14 out of 16 patients. Five patients received the entire planned treatment, and the compliance was higher after amendments of the protocol. Among the 15 SAEs, 6 were unexpected. Grade (G) 3/4 acute toxic effects, observed in 88% patients, were general (n = 13, 81%), digestive (n = 9, 56%), dermatological (n = 5, 31%), infectious (n = 4, 25%), haematological (n = 3, 19%), and others (n = 9); and three patients suffered from six G3/4 late toxic effects. No treatment-related death was reported. All 11 assessable patients had an objective response consisting of six complete (55%) and five partial (45%) response 2 months after the end of the treatment. Thirteen patients were followed up with a median of 22 months [95% confidence interval (CI): 18-27] and had a 1-year colostomy-free survival, progression-free and overall survival rate of 67% (95% CI: 40%-86%), 62% (95% CI: 36%-82%), and 92% (95% CI: 67%-99%), respectively. Conclusion: CRT plus cetuximab was unacceptably toxic in this population of patients. Results of others phase II trials evaluating this combination are awaited to confirm these findings. © The Author 2013.

Background: Brain metastases occur in 30-50% of patients with metastatic HER2-positive breast cancer. In the case of diffuse brain metastases, treatment is based on whole brain radiotherapy (WBRT). Few systemic options are available. We aimed to investigate the combination of lapatinib plus capecitabine for the treatment of previously untreated brain metastases from HER2-positive breast cancer. Methods: In this single-arm phase 2, open-label, multicentre study, eligible patients had HER2-positive metastatic breast cancer with brain metastases not previously treated with WBRT, capecitabine, or lapatinib. Tretament was given in 21 day cycles: patients received lapatinib (1250 mg, orally) every day and capecitabine (2000 mg/m2, orally) from day 1 to day 14. The primary endpoint was the proportion of patients with an objective CNS response, defined as a 50% or greater volumetric reduction of CNS lesions in the absence of increased steroid use, progressive neurological symptoms, and progressive extra-CNS disease. All responses had to be confirmed 4 weeks after initial response. Efficacy analyses included all patients who received the study drugs and were assessable for efficacy criteria. This trial is registered with ClinicalTrials.gov, number NCT00967031. Findings: Between April 15, 2009, to Aug 2, 2010, we enrolled 45 patients, 44 (98%) of whom were assessable for efficacy, with a median follow-up of 21·2 months (range 2·2-27·6). 29 patients had an objective CNS response (65·9%, 95% CI 50·1-79·5); all were partial responses. Of all 45 treated patients, 22 (49%) had grade 3 or grade 4 treatment-related adverse events, of which the most common were diarrhoea in nine (20%) patients and hand-foot syndrome in nine (20%) patients. 14 (31%) patients had at least one severe adverse event; treatment was discontinued because of toxicity in four patients. No toxic deaths occurred. Interpretation: The combination of lapatinib and capecitabine is active as first-line treatment of brain metastases from HER2-positive breast cancer. A phase 3 trial is warranted. Funding: GlaxoSmithKline-France and UNICANCER. © 2013 Elsevier Ltd.

Background: Papillary renal cell carcinoma (PRCC), type 1 and type 2, represents 10%-15% of renal cell carcinomas (RCC). There is no standard first-line treatment of metastatic PRCC (mPRCC). Anti-angiogenics have shown activity in retrospective studies but no prospective studies in pure papillary histology have been reported, but one with foretinib. Patients and methods: A prospective phase II study evaluated sunitinib in first-line treatment of mPRCC. The primary end point was overall response rate (ORR). Secondary end points were progression-free survival (PFS) and overall survival (OS). Results: Fifteen and 46 patients, respectively, with type 1 and type 2 mPRCC were enrolled. Using the MSKCC scoring system: 12 (20%), 33 (55%) and 9 (15%) patients were, respectively, in the favourable, intermediate or poor risk group and 7 undetermined. Median follow-up is 51.4 months. In type 1, 2 patients 13% [95% confidence interval (CI) 0.1-30.5] had a partial response (PR), 10 had stable disease (SD) with 5 (33%) ≥12 weeks. In type 2, 5 patients 11% (95% CI 1.9-20.3) had a PR, 25 had SD with 10(22%) ≥12 weeks. Median PFS was 6.6 months (95% CI 2.8-14.8) in type 1 and 5.5 months (95% CI 3.8-7.1) in type 2. Median OS was 17.8 (95% CI 5.7-26.1) and 12.4 (95% CI 8.2-14.3) months, respectively, in type 1 and 2. Safety was as expected with sunitinib for metastatic RCC. Conclusion: Sunitinib showed activity in treatment of type 1 and 2 mPRCC but lower than in clear-cell mRCC. Both PFS and OS are longer in type I PRCC. Sunitinib represents an acceptable option in first-line treatment of mPRCC. © The Author 2015.

Background: Early risk-stratified chemotherapy is a standard treatment for breast, colorectal, and lung cancers, but not for high-risk localised prostate cancer. Combined docetaxel and estramustine improves survival in patients with castration-resistant prostate cancer. We assessed the effects of combined docetaxel and estramustine on relapse in patients with high-risk localised prostate cancer. Methods: We did this randomised phase 3 trial at 26 hospitals in France. We enrolled patients with treatment-naive prostate cancer and at least one risk factor (ie, stage T3-T4 disease, Gleason score of ≥8, prostate-specific antigen concentration >20 ng/mL, or pathological node-positive). All patients underwent a staging pelvic lymph node dissection. Patients were randomly assigned (1:1) to either androgen deprivation therapy (ADT; goserelin 10·8 mg every 3 months for 3 years) plus four cycles of docetaxel on day 2 at a dose of 70 mg/m2 and estramustine 10 mg/kg per day on days 1-5, every 3 weeks, or ADT only. The randomisation was done centrally by computer, stratified by risk factor. Local treatment was administered at 3 months. Neither patients nor investigators were masked to treatment allocation. The primary endpoint was relapse-free survival in the intention-to-treat population. Follow-up for other endpoints is ongoing. This study is registered with ClinicalTrials.gov, number NCT00055731. Findings: We randomly assigned 207 patients to the ADT plus docetaxel and estramustine group and 206 to the ADT only group. Median follow-up was 8·8 years (IQR 8·1-9·7). 88 (43%) of 207 patients in the ADT plus docetaxel and estramustine group had an event (relapse or death) versus 111 (54%) of 206 in the ADT only group. 8-year relapse-free survival was 62% (95% CI 55-69) in the ADT plus docetaxel and estramustine group versus 50% (44-57) in the ADT only group (adjusted hazard ratio [HR] 0·71, 95% CI 0·54-0·94, p=0·017). Of patients who were treated with radiotherapy and had data available, 31 (21%) of 151 in the ADT plus docetaxel and estramustine group versus 26 (18%) of 143 in the ADT only group reported a grade 2 or higher long-term side-effect (p=0·61). We recorded no excess second cancers (26 [13%] of 207 vs 22 [11%] of 206; p=0·57), and there were no treatment-related deaths. Interpretation: Docetaxel-based chemotherapy improves relapse-free survival in patients with high-risk localised prostate cancer. Longer follow-up is needed to assess whether this benefit translates into improved metastasis-free survival and overall survival.

Background: Poor prognosis germ-cell tumours are only cured in about half of patients. We aimed to assess whether treatment intensification based on an early tumour marker decline will improve progression-free survival for patients with germ-cell tumours. Methods: In this phase 3, multicentre, randomised trial, patients were enrolled from France (20 centres), USA (one centre), and Slovakia (one centre). Patients were eligible if they were older than 16 years, had evidence of testicular, retroperitoneal, or mediastinal non-seminomatous germ cell tumours based on histological findings or clinical evidence and highly elevated serum human chorionic gonadotropin or alfa-fetoprotein concentrations that matched International Germ Cell Cancer Consensus Group poor prognosis criteria. After one cycle of BEP (intravenous cisplatin [20 mg/m2 per day for 5 days], etoposide [100 mg/m2 per day for 5 days], and intramuscular or intravenous bleomycin [30 mg per day on days 1, 8, and 15]), patients' human chorionic gonadotropin and alfa-fetoprotein concentrations were measured at day 18-21. Patients with a favourable decline in human chorionic gonadotropin and alfa-fetoprotein continued BEP (Fav-BEP group) for 3 additonal cycles, whereas patients with an unfavourable decline were randomly assigned (1:1) to receive either BEP (Unfav-BEP group) or a dose-dense regimen (Unfav-dose-dense group), consisting of intravenous paclitaxel (175 mg/m2 over 3 h on day 1) before BEP plus intravenous oxaliplatin (130 mg/m2 over 3 h on day 10; two cycles), followed by intravenous cisplatin (100 mg/m2 over 2 h on day 1), intravenous ifosfamide (2 g/m2 over 3 h on days 10, 12, and 14), plus mesna (500 mg/m2 at 0, 3, 7 and 11 h), and bleomycin (25 units per day, by continuous infusion for 5 days on days 10-14; two cycles), with granulocyte-colony stimulating factor (lenograstim) support. Centrally blocked computer-generated randomisation stratified by centre was used. The primary endpoint was progression-free survival and the efficacy analysis was done in the intention-to-treat population. The planned trial accrual was completed in May, 2012, and follow-up is ongoing. This study is registered with ClinicalTrials.gov, number NCT00104676. Findings: Between Nov 28, 2003, and May 16, 2012, 263 patients were enrolled and 254 were available for tumour marker assessment. Of these 51 (20%) had a favourable marker assessment, and 203 (80%) had an unfavourable tumour marker decline; 105 were randomly assigned to the Unfav-dose-dense group and 98 to the Unfav-BEP group. 3-year progression-free survival was 59% (95% CI 49-68) in the Unfav-dose-dense group versus 48% (38-59) in the Unfav-BEP group (HR 0.66, 95% CI 0.44-1.00, p=0.05). 3-year progression-free survival was 70% (95% CI 57-81) in the Fav-BEP group (HR 0.66, 95% CI 0.49-0.88, p=0.01 for progression-free survival compared with the Unfav-BEP group). More grade 3-4 neurotoxic events (seven [7%] vs one [1%]) and haematotoxic events occurred in the Unfav-dose-dense group compared with in the Unfav-BEP group; there was no difference in grade 1-2 febrile neutropenia (18 [17%] vs 18 [18%]) or toxic deaths (one [1%] in both groups). Salvage high-dose chemotherapy plus a stem-cell transplant was required in six (6%) patients in the Unfav-dose-dense group and 16 (16%) in the Unfav-BEP group. Interpretation: Personalised treatment with chemotherapy intensification reduces the risk of progression or death in patients with poor prognosis germ-cell tumours and an unfavourable tumour marker decline. © 2014 Elsevier Ltd.

26 Background: Patients with upfront metastases at the time of prostate cancer (PC) diagnosis are less frequent than in the past in Western countries, but still represent 5-10% of all patients and almost one half of PC patients will eventually die of the disease. Prognostic factors (lymph node metastases/appendicular vs axial bone disease, performance status > 1, Gleason score > 8 and PSA > 65 ng/ml) have been proposed (Glass et al., 2003), leading to the definition of three subgroups with good, intermediate and poor prognosis. However, the current natural history of metastatic prostate cancer has not been well described.Patients with hormone sensitive metastatic PC were randomized to receive continuous androgen deprivation therapy (ADT) plus docetaxel (75 mg/m/21d up to 9 cycles) and prednisone or ADT alone. Glass risk groups were used as stratification factors.From October 2004 to December 2008, 385 pts were included. They were distributed into good (50%), intermediate (29%), and poor (21%) prognosis groups. The median follow up was 50 months [95% CI: 49 - 54]. The primary endpoint analysis showed no difference in overall survival (OS) (HR: 1.01 [95%CI: 0.75-1.36]) between the 2 arms but a significant PFS improvement was observed in the docetaxel group (HR: 0.75 [0.59-0.94] p=0.0147) (Gravis, ESMO 2012). The median OS in the ADT alone arm was 54 months [42-NR]. It was 69 [95% CI: 60.9-NR], 47 [95% CI: 37.7-NR, HR = 1.6] and 37 [95% CI: 28.5-58.9, HR = 2.12] months respectively in the good, intermediate, and poor prognosis groups (p=0.001) in the whole cohort. No interaction between prognosis groups and treatment was found. A detailed analysis using the Cox model will be presented.At the present time, median life expectancy of patients with metastatic PC seems to exceed 4 years. Subgroups with favorable or unfavorable outcome can be identified.NCT00055731.

Background: During the ACCORD 12 randomized trial, an evaluation of the clinical tumor response was prospectively performed after neoadjuvant chemoradiotherapy. The correlations between clinical complete response and patient characteristics and treatment outcomes are reported. Material and methods: Between 2005 and 2008 the Accord 12 trial accrued 598 patients with locally advanced rectal cancer and compared two different neoadjuvant chemoradiotherapies (Capox 50: capecitabine + oxaliplatin + 50 Gy vs Cap 45: capecitabine + 45 Gy). An evaluation of the clinical tumor response with rectoscopy and digital rectal examination was planned before surgery. A score to classify tumor response was used adapted from the RECIST definition: complete response: no visible or palpable tumor; partial response, stable and progressive disease. Results: The clinical tumor response was evaluable in 201 patients. Score was: complete response: 8% (16 patients); partial response: 68% (137 patients); stable: 21%; progression: 3%. There was a trend toward more complete response in the Capox 50 group (9.3% vs 6.7% with Cap 45). In the whole cohort of 201 pts complete response was significantly more frequent in T2 tumors (28%; p = 0.025); tumors <4 cm in diameter (14%; p = 0.017), less than half rectal circumference and with a normal CEA level. Clinical complete response observed in 16 patients was associated with more conservative treatment (p = 0.008): 2 patients required an abdomino-perineal resection, 11 an anterior resection and 3 patients benefited from organ preservation (2 local excision, 1 "watch and wait". A complete response was associated with more ypT0 (73%; p < 0.001); ypNO (92%); R0 circumferential margin (100%). Conclusion: These data support the hypothesis that a clinical complete response assessed using rectoscopy and digital rectal examination after neoadjuvant therapy may increase the chance of a sphincter or organ preservation in selected rectal cancers. © 2015 Elsevier Ireland Ltd.

LBA4500 Background: Poor-prognosis GCT (IGCCCG, J Clin Oncol 1997) remains a challenge with no improvement in the 50% survival demonstrated in phase III trials for 25 years. Day 21 serum tumor marker decline rate identified a subgroup of patients (pts) with a better outcome (J Clin Oncol 2004, 22: 3868-76). The hypothesis we tested in this study is that treatment allocation based on early tumor marker decline will improve the progression-free survival (PFS).Pts with IGCCCG poor-prognosis GCT were treated with a first cycle of BEP. AFP and hCG were assessed at day 18-21: 1) Pts with a favorable decline continued BEP for a total of 4 courses (Fav-BEP); 2) Pts with an unfavorable decline were randomized to receive either BEP (Unfav-BEP) or a dose-dense regimen (Unfav-dose-dense), consisting of paclitaxel-BEP plus day-10 oxaliplatin x 2 cycles, followed by 2 cycles of cisplatin, ifosfamide, and continuous infusion bleomycin (depending on lung function) + G-CSF. The primary endpoint was PFS (hypothesis: 20% difference, type 1 error: 5%, power 80%, 196 randomized pts needed).263 pts were enrolled and 254 were evaluable at day 21 (6 early deaths, 3 withdrawals): 51 pts (20%) had favorable tumor marker decline and 203 had unfavorable decline (randomized: 105 Unfav-dose-dense arm, 98 Unfav-BEP). The prognostic value of early tumor marker decline (Fav-BEP vs Unfav-BEP) was confirmed: 70% vs 48% for 3-year PFS (p=0.01), and 84% vs 65% for overall survival (OS) (p=0.02). The 3-year PFS was 59% in the Unfav-dose-dense arm vs 48% in the Unfav-BEP arm (p=0.05; HR: 0.66 [0.44-1.00]). 3-year OS was 73% and 65%, respectively. More grade 2 neurotoxicity (21% vs 4%) and more hematotoxicity occurred in the dose-dense arm, with no excess febrile neutropenia (17% each arm) or toxic deaths (1 each arm). Salvage high-dose chemotherapy + stem-cell transplant were required in 6% in the Unfav-dose-dense arm and 16% in the Unfav-BEP arm (p=0.01).An algorithm of individualized treatment intensification determined by the rate of early tumor marker decline reduces the risk of progression or death in men with poor-prognosis GCT.NCT00104676.
