Background: Borderline ovarian tumors (BOTs) are a subset of epithelial ovarian tumors with low malignant potential but significant risk of relapse (10% to 30%). Unfortunately, surgical prognostic factors for BOT relapse have not been clearly identified, probably due to the use of heterogeneous surgical definitions and limited follow-up. The aim of this study was to assess potential relapse risk factors using standard surgical definitions and long follow-up.Methods: All patients diagnosed with BOT for a period of more than 10 years in a single institution were included in the analysis. Complete surgical staging was defined as the set of procedures that follow standard guidelines for staging surgery (except lymphadenectomy), performed either with one or two interventions. Fertility-sparing surgeries that preserved one ovary and the uterus but included all the remaining procedures were classified as complete staging. The relationship between potential risk factors and time to BOT relapse was assessed by log-rank tests corrected for multiple comparisons and Cox regression.Results: Forty-six patients with a median follow-up of 5.4 years were included, of whom 91.3% had been diagnosed as FIGO stage I disease and 45.7% had received complete staging surgery. Five relapses were detected (10.9%), all of them in women who had been diagnosed with stage I disease and had received incomplete staging surgery. Log-rank tests confirmed the association between incomplete staging surgery and shorter time to BOT relapse.Conclusions: Complete staging surgery should be considered a cornerstone of BOT treatment in order to minimize the risk of relapse. © 2013 Romeo et al.; licensee BioMed Central Ltd.

Background: We conducted a phase I study in patients with advanced solid tumours to identify the recommended dose, assess pharmacokinetics (PK), pharmacodynamic activity and preclinical antitumour efficacy of the combination of sirolimus and gemcitabine. Methods: Nineteen patients were treated with sirolimus 2 or 5 mg daily and gemcitabine 800 or 1000 mg m-2 on days 1 and 8. Dose escalation depended on dose-limiting toxicity (DLT) rate during the first 3-week period. Paired skin biopsies were evaluated for phosphorylated S6 (pS6) as marker of mTOR (mammalian target of rapamycin) inhibition. Pharmacokinetics and preclinical evaluation of efficacy using two different sarcoma cell lines and leiomyosarcoma xenografts were also conducted. Results: Three DLTs were observed: grade 3 transaminitis, grade 3 thrombocytopenia and grade 4 thrombocytopenia. Common treatment-related adverse events included anaemia, neutropenia, thrombocytopenia and transaminitis. Pharmacodynamic analyses demonstrated mTOR inhibition with sirolimus 5 mg and PK showed no influence of sirolimus concentrations on gemcitabine clearance. In vitro and in vivo studies suggested mTOR pathway hyperactivation by gemcitabine that was reversed by sirolimus. Tumour growth in leiomyosarcoma xenografts was dramatically inhibited by the treatment. Conclusions: Recommended dose was sirolimus 5 mg per 24 h plus gemcitabine 800 mg m-2. Antitumour activity in preclinical sarcoma models and mTOR signalling inhibition were observed. A phase II study is currently ongoing. © 2014 Cancer Research UK.

Nasopharyngeal carcinoma cases are not frequently encountered in our environment. Local stages are treated with radiotherapy. For advanced local stages, the association of chemotherapy with radiotherapy improves the rates of survival. In the case of metastatic disease stages, treatment requires platinum-based chemotherapy and patients may achieve a long survival time. © 2013 Federación de Sociedades Españolas de Oncología (FESEO).

Soft tissue sarcomas are uncommon tumors of mesenchimal cell origin. Criteria for suspicion is a soft tissue mass that is increasing in size, and has a size greater than 5 cm or is located under the deep fascia. Diagnosis and management of these patients should preferably be performed by a specialist multidisciplinary team in a referral center. Assessment of a patient with a suspect of sarcoma should include magnetic resonance and biopsy performed prior to surgery. Primary local therapy for patients with localized sarcoma is based on wide surgical resection with a tumor-free tissue margin, in association in most cases with radiotherapy. Adjuvant chemotherapy constitutes an option that could be considered in high-risk sarcomas of the extremities. When metastasis are present, surgery of pulmonary lesions, in some selected patients, and chemotherapy are current available options.

Background: Cetuximab combined with radiotherapy (RT) is a treatment option for head and neck cancer. The objectives of this randomized, phase II trial were to evaluate the efficacy and safety of cetuximab maintenance therapy following definitive RT with concomitant cetuximab in patients with oropharyngeal cancer. Patients and methods: Ninety-one patients with stage III-IV M0 oropharyngeal tumors were randomly assigned to the treatment with accelerated concomitant boost RT (69.9 Gy) + cetuximab or the same treatment with the addition of 12 consecutive weeks of cetuximab maintenance therapy. The primary end point was locoregional control (LRC) at 1 year. Results: LRC at 1 year was superior among patients in the experimental arm, treated with cetuximab maintenance (59% versus 47%). However, LRC was similar between both arms after 2 years of follow-up, as a result of increased locoregional recurrences after the first year in the maintenance group. Patients treated with adjuvant cetuximab do recover very soon from toxic effect after combined treatment. Conclusions: Twelve weeks of cetuximab maintenance therapy after concomitant cetuximab + RT in locally advanced oropharyngeal carcinoma is feasible and improves clinical outcomes measured at 1 year. This improvement is not maintained after the second year suggesting that epidermal growth factor receptor blockade is not sufficient to completely eliminate the minimal residual disease. © The Author 2012.

The purpose of this article was to provide updated recommendations for the diagnosis and treatment of renal cell carcinoma. Pathological confirmation is mandatory before treatment with ablative or focal therapies before any type of systemic therapy. Renal cell cancer should be staged according to the TNM classification system. A laparoscopic nephron-sparing surgery should be the approach for tumors <4 cm if technically feasible. Otherwise, radical (or partial in selected cases) nephrectomy is the treatment of choice, with lymph node dissection only performed in patients with clinically detected lymph node involvement. Some retrospective evidence for a cytoreductive nephrectomy in the postimmunotherapy era suggests a benefit in patients with good or intermediate risk or for patients with a symptomatic primary lesion. Adjuvant treatment with chemotherapy or with targeted agents is not recommended and studies are ongoing today. Patients with metastatic disease should be staged by computed tomography scans of the chest, abdomen and pelvis. The efficacy of sunitinib, bevacizumab plus interferon-α, and pazopanib is well established in patients with good and intermediate risk as well for temsirolimus in poor-risk patients. These four agents are considered standard of care in first-line treatment. Sorafenib, axitinib and everolimus are standard of care in second line in different settings based on their benefit in PFS. Besides some benefit described for IL-2 in highly selected patients in first line, there is a promising and emerging role for the new immunotherapeutic approaches in metastatic renal cell carcinoma. © 2014, The Author(s).

Soft tissue sarcomas (STS) constitute an uncommon and heterogeneous group of tumours, which require a complex and specialized multidisciplinary management. The diagnostic approach should include imaging studies and core needle biopsy performed prior to undertaking surgery. Wide excision is the mainstay of treatment for localized sarcoma, and associated preoperative or postoperative radiotherapy should be administered in high-risk patients. Adjuvant chemotherapy was associated with a modest improvement in survival in a meta-analysis and constitutes a standard option in selected patients with high-risk STS. In metastatic patients, surgery must be evaluated in selected cases. In the rest of patients, chemotherapy and, in some subtypes, targeted therapy often used in a sequential strategy constitutes the treatment of election. Despite important advances in the understanding of the pathophysiology of the disease, the advances achieved in therapeutic results may be deemed still insufficient. Moreover, due to the rarity and complexity of the disease, the results in clinical practice are not always optimal. For this reason, the Spanish Group for Research on Sarcoma (GEIS) has developed a multidisciplinary clinical practice guidelines document, with the aim of facilitating the diagnosis and treatment of these patients in Spain. In the document, each practical recommendation is accompanied by level of evidence and grade of recommendation on the basis of the available data.

To examine the relationship between polymorphisms of the epidermal growth factor receptor (EGFR) pathway and toxicity in head and neck squamous cell carcinoma (HNSCC) patients treated with cetuximab.Multicenter, retrospective, observational pilot study which included 110 patients with histologically-confirmed human papillomavirus (HPV) negative HNSCC in locally advanced stages (III-IVA-B) and who were treated with chemotherapy and radiotherapy plus cetuximab between 2003 and 2013. Genetic analyses for single nucleotide polymorphisms (SNP) in genes EGFR, CCDN1, FCGR2A, FCGR3A and KRAS-LCS6 were performed though available allelic discrimination assay and/or polymerase chain reaction-restriction fragment length polymorphism methods.Acneiform rash was observed in 55.5% of patients, dry skin in 45.5% and pruritus in 20.9%. A significant association with dry skin and global cetuximab-related toxicity was observed for the KRAS-LCS6 (rs61764370) variant (p<0.05); carriers of the G allele (genotypes TG+GG) in the dominant model were observed to have a decreased susceptibility of developing dry skin (OR=0.287 [95%CI=0.119-0.695]). Carriers of the A (GA+AA) allele for EGFR (rs2227983) showed a decreased risk of suffering from pruritus (OR=0.345 [0.124-0.958]). Similarly, KRAS (rs1801274) was related with lower global cetuximab-related toxicity (OR=0.266 [0.114-0.622]).This pilot study provides preliminary evidence supporting genetic variation of EGFR (rs2227983), KRAS (rs61764370) and FCGR2A (rs180127) as useful biomarkers for predicting reduced skin toxicity in HNSCC patients treated with a cetuximab-based therapy. Alternative therapeutic options should be explored for these patients.

Phosphatidylinositol 3-kinase (PI3K) pathway activation in squamous cell carcinoma of the head and neck contributes to treatment resistance and disease progression. Buparlisib, a pan-PI3K inhibitor, has shown preclinical antitumour activity and objective responses in patients with epithelial malignancies. We assessed whether the addition of buparlisib to paclitaxel improves clinical outcomes compared with paclitaxel and placebo in patients with recurrent or metastatic squamous cell carcinoma of the head and neck.In this multicentre, randomised, double-blind, placebo-controlled phase 2 study (BERIL-1), we recruited patients aged 18 years and older with histologically or cytologically confirmed recurrent and metastatic squamous cell carcinoma of the head and neck after disease progression on or after one previous platinum-based chemotherapy regimen in the metastatic setting. Eligible patients were enrolled from 58 centres across 18 countries and randomly assigned (1:1) to receive second-line oral buparlisib (100 mg once daily) or placebo, plus intravenous paclitaxel (80 mg/mBetween Nov 5, 2013, and May 5, 2015, 158 patients were enrolled and randomly assigned to receive either buparlisib plus paclitaxel (n=79) or placebo plus paclitaxel (n=79). Median progression-free survival was 46 months (95% CI 35-53) in the buparlisib group and 35 months (22-37) in the placebo group (hazard ratio 065 [95% CI 045-095], nominal one-sided p=0011). Grade 3-4 adverse events were reported in 62 (82%) of 76 patients in the buparlisib group and 56 (72%) of 78 patients in the placebo group. The most common grade 3-4 adverse events (occurring in 10% of patients in the buparlisib group vs the placebo group) were hyperglycaemia (17 [22%] of 76 vs two [3%] of 78), anaemia (14 [18%] vs nine [12%]), neutropenia (13 [17%] vs four [5%]), and fatigue (six [8%] vs eight [10%]). Serious adverse events (regardless of relation to study treatment) were reported for 43 (57%) of 76 patients in the buparlisib group and 37 (47%) of 78 in the placebo group. On-treatment deaths occurred in 15 (20%) of 76 patients in the buparlisib group and 17 (22%) of 78 patients in the placebo group; most were caused by disease progression and none were judged to be related to study treatment.On the basis of the improved clinical efficacy with a manageable safety profile, the results of this randomised phase 2 study suggest that buparlisib in combination with paclitaxel could be an effective second-line treatment for patients with platinum-pretreated recurrent or metastatic squamous cell carcinoma of the head and neck. Further phase 3 studies are warranted to confirm this phase 2 finding.Novartis Pharmaceuticals Corporation.

Toevaluate the efficacy and safety of induction chemotherapy (IC) followed by bioradiotherapy (BRT) to achieve functional larynx preservation in the setting of locally advanced head and neck tumors.This was a phase 2, open-label, multicenter study of patients with stage III and IVA laryngeal carcinoma who were candidates for total laryngectomy. Theprimary endpoint was the rate of survival with functional larynx (SFL) at 3years, with a critical value to consider the study positive of SFL >59%. Patients received 3 cycles of IC with TPF (docetaxel, cisplatin, and 5-fluorouracil), and those who responded received conventional BRT with cetuximab. In patients with residual nodal disease after BRT, neck dissection was planned 2months after BRT. Patients who did not respond to IC underwent total laryngectomy plus neck dissection and radiation therapy.A total of 93 patients started TPF. Responses to IC on larynx target lesion were as follows: 37 patients (40%) showed a complete response; 38 patients (41%) showed a partial response; 8 patients (9%) showed stabilization; 2 patients (2%) showed progressive disease, and 8 patients (9%) were not evaluated (2 deaths, 5 adverse events, and 1 lost to follow-up). Seventy-three patients (78%) received BRT: 72 as per protocol, but 1 with only stable disease. Median follow-up was 53.7months. Three-year actuarial rates were as follows: SFL: 70% (95% confidence interval [CI] 60%-79%); laryngectomy-free survival: 72% (95% CI 61%-81%); overall survival: 78% (95% CI: 63%-82%). The acute toxicity observed during both IC and BRT was as expected, with only 1 toxicity-related death (local bleeding) during BRT.According to this protocol, the SFL rate was clearly higher than the critical value, with acceptable levels of toxicity. The use of cetuximab added to radiation therapy in patients with stage III and IVA laryngeal cancer who respond to TPF could improve functional larynx preservation. A phase 3 trial is warranted.
