RESUMEN
BACKGROUND: This article describes and compares approved targeted therapies and the newer immunotherapy agents. MATERIALS AND METHODS: This article especially performs an in-depth review of currently available data for tivozanib, explaining its mechanism of action, its safety profile and its role as an efficacy drug in the management of renal cancer. RESULTS: Despite the fact that the treatment of advanced RCC has been dramatically modified in recent years, durable remissions are scarce and it remains a lethal disease. For first- and second-line therapy, there is now growing evidence to guide the selection of the appropriate treatment. CONCLUSIONS: Several TKIs are standard of care at different settings. Among those approved TKIs, tivozanib has similar efficacy than others with a better safety profile. The use of prognostic factors is critical to the selection of optimal therapy.

PURPOSE: The aim of this phase II study was to evaluate the activity and safety of the combination of cisplatin and vinorelbine with thoracic radiotherapy in unresectable locally advanced stage III non-small cell lung cancer (NSCLC). The primary endpoint was the objective response rate (ORR). Secondary objectives included toxicity profile, progression-free survival (PFS), and overall survival (OS). MATERIALS AND METHODS: A total of 48 NSCLC patients were enrolled (median age 60 years, 52% stage IIIA and 48% stage IIIB, 52% adenocarcinoma). Patients received three cycles of chemotherapy every 21 days [intravenous cisplatin 80 mg/m2 and intravenous vinorelbine 25 mg/m2 on day 1 and oral vinorelbine on day 8 (60 mg/m2)] concurrent with radiotherapy (66 Gy, administered at 1.8 Gy per day, five consecutive days per week). RESULTS: ORR was 79.2% (72.9% showing partial response and 6.3% showing complete response). With a median follow-up of 20.7 months, median PFS was 12 months and median OS was 36 months. Grade 3/4 toxicities were: neutropenia (14.5%), anaemia (6.2%), vomiting (2%), and oesophagitis (4.2%). No toxic deaths were reported. CONCLUSION: This combined regimen shows efficacy and a manageable safety profile. PFS and OS outcomes are encouraging and warrant further research.

PURPOSE: Head and neck cancer is a highly heterogeneous disease comprising a large number of tumors located in the cervicofacial area. This study aimed to determine the epidemiological characteristics of squamous-cell carcinomas of the head and neck in the Spanish population, and the distribution of risk factors based on tumor locations. METHODS/PATIENTS: A cohort of 459 patients (75 oral cavity, 167 oro-/hypopharyngeal and 217 laryngeal cancers) recruited in 19 hospitals participating in the Spanish head and neck cancer cooperative group were included over 3 years (2012-2014). Epidemiological parameters and risk factors were obtained from a self-administered questionnaire, and tumor characteristics were obtained from clinical records. Multivariate multinomial logistic regression was used to assess factors associated with tumor location. RESULTS: Most patients were males (88.4 %), smokers (95 %) and drinkers (76.5 %). Relative to laryngeal cancer, pharyngeal cancer and oral cancer were more common in women than men (OR 3.58, p = 0.003 and 4.33, p = 0.001, respectively); pharyngeal cancer was more associated with rural environment (OR 1.81, p = 0.007) and weekly alcohol intake (10-140 g: OR 2.53, p = 0.012; 141-280 g: OR 2.47, p = 0.023; >280 g: OR 3.20, p = 0.001) and less associated with pack-years of smoking (21-40 packs: OR 0.46, p = 0.045; 41-70 packs: OR 0.43, p = 0.023; ≥71 packs: OR 3.20, p = 0.015). CONCLUSIONS: The distribution of these tumors differs between the sexes, with a higher proportion of oral cavity and pharyngeal tumors in women than in men. Oro-/hypopharyngeal cancers were more strongly associated with rural areas and with alcohol consumption, although less strongly associated with smoking than laryngeal tumors.

BACKGROUND: Brain metastases of testicular germ cell tumor (TGCT) are a rare event. Prognostic is poor and there is not much evidence on optimal management of these patients. PATIENTS AND METHODS: A review of case records of germ cell tumor patients within the Spanish Germ Cell Cancer Group data base from 1994 to 2012 was conducted. RESULTS: Thirty-three out of 6,200 cases (0.5 %). Nineteen patients (57 %) group 1: synchronous, 13 (40 %) group 2: metachronous and only one developed brain metastasis during cisplatin-based chemotherapy (excluded from the analysis). Median serum BHCG levels at initial diagnosis was higher in group 1, whereas elevated AFP serum levels were more common in group 2. Histology in the primary tumor: chorionic carcinoma for group 1 versus embryonal carcinoma for group 2. Mainly solitary brain metastasis in group 2 (54 versus 21 %, respectively). The median overall survival from the diagnosis of central nervous system involvement was 16 months for group 1 (CI 95 % 13.9-18) and 23 months (95 % CI 0-165) for group 2 (log rank p = 0.84). Long-term survivors were practically identical in the two groups (38.9 % group 1 versus 38.5 % group 2). Regardless of the timing of brain metastasis, those patients that achieved complete response to the treatment had better survival (log rank p 0.003). CONCLUSION: Although some distinctive clinical characteristics have been found between patients with synchronous versus metachronous brain metastasis from TGCT, the timing of brain metastasis did not seem to have prognostic influence, but due to the retrospective nature of the analysis and the results should be interpreted with caution.

We performed a literature search that shed light on the signaling pathways involved in the sorafenib activity as first- or subsequent-line treatment, taking into account its toxicity profile. Sorafenib appears to have better tolerability when compared with other agents in the same indication. Cross-resistance between tyrosine kinase inhibitors (TKIs) may be limited, even after failure with a previous VEGFR inhibitor, but the optimal sequence with TKIs remains to be determined. Randomized trials of second-line treatment options have showed either modest or no differences in terms of progression-free and overall survival (OS). Direct comparison between sorafenib and axitinib demonstrated differences in terms of PFS in favor of axitinib, but not in terms of OS as second-line treatment. In contrast, a phase III study showed a benefit in OS, favoring sorafenib when compared with temsirolimus. In conclusion, after using other VEGF inhibitor such as sunitinib, sorafenib is active and safe for the treatment of patients with advanced or metastatic RCC.
