Papillary renal cell carcinoma: A review of the current therapeutic landscape.

Renal cell carcinoma (RCC) is the most common cancer of the kidney and accounts for 2-3% of all adult malignancies. Clear cell carcinoma represents the most common histologic subtype, while papillary Renal Cell Carcinoma (pRCC) accounts for 10-20% of all renal cell cancers. While the inactivation of VHL gene can be found in the majority of clear cell carcinomas, different molecular mechanisms are involved into pRCC biology. Mutations in the MET oncogene are an essential step into the pathogenesis of hereditary pRCC forms, but they can be found only in a small rate of sporadic cases. Several agents, including anti-VEGF drugs and mTOR inhibitors, are possible options in the treatment of advanced and metastatic pRCC, following the demonstration of efficacy obtained in clinical trials including all RCC histologic subtypes. However, data specifically obtained in the subgroup of patients affected by pRCC are limited and not conclusive. Several ongoing trials are evaluating the efficacy of targeted therapy in papillary form. However, more rationale approaches based on molecular studies would help improving the outcome of these patients. Among others, MET inhibitors and targeted immunotherapy are promising new strategies for hereditary and sporadic disease. This review summarizes current knowledge on pRCC tumorigenesis and discusses recent and ongoing clinical trials with new therapeutic agents.

Cancer survivorship: long-term side-effects of anticancer treatments of gastrointestinal cancer.

PURPOSE OF REVIEW: Surveillance of patients with a history of cancer is a frequent practice in oncology. However, it is often aimed at the early diagnosis of relapse and tends to underestimate the evaluation and care of factors impairing quality of life (QoL). Among these, long-term toxicities of anticancer treatments are one of the major threats to a complete physical and psychosocial recovery. We aimed to review the relevant literature on long-term side-effects of treatment in gastrointestinal cancers. RECENT FINDINGS: We focused on esophageal, gastric, pancreatic, liver and colorectal cancers. A significant fraction of patients treated for these cancers suffer with some form of late toxicity from surgery, radiotherapy or chemotherapy. Prompt evaluation and management is of the utmost importance in reducing the impact of these symptoms on QoL. SUMMARY: The knowledge of the reviewed data should encourage a multidisciplinary approach to surveillance and convince clinicians of the comprehensive role of survivorship care.

Hospital admission of cancer patients: avoidable practice or necessary care?

BACKGROUND: Cancer patients are frequently admitted to hospital due to acute conditions or refractory symptoms. This occurs through the emergency departments and requires medical oncologists to take an active role. The use of acute-care hospital increases in the last months of life. PATIENTS AND METHODS: We aimed to describe the admissions to a medical oncology inpatient service within a 16-month period with respect to patients and tumor characteristics, and the outcome of the hospital stay. RESULTS: 672 admissions of 454 patients were analysed. The majority of admissions were urgent (74.1%), and were due to uncontrolled symptoms (79.6%). Among the chief complaints, dyspnoea occurred in 15.7%, pain in 15.2%, and neurological symptoms in 14.5%. The majority of the hospitalizations resulted in discharge to home (60.6%); in 26.5% the patient died and in 11.0% was transferred to a hospice. Admissions due to symptoms correlated with a longer hospital stay and a higher incidence of in-hospital death. CONCLUSION: We suggest that hospital use is not necessarily a sign of inappropriately aggressive care: inpatient care is probably an unavoidable step in the cancer trajectory. Optimization of inpatient supportive procedures should be a specific task of modern medical oncology.

The role of microRNA in head and neck cancer: current knowledge and perspectives.

Head and neck cancer is one of the most commonly diagnosed malignancies worldwide. Patients with advanced disease stages frequently develop recurrences or distant metastasis, which results a five-year survival rates of less than 60% despite considerable advances in multimodality therapy. A better understanding of molecular basis of tumorigenesis is required to improve clinical outcomes and to develop new anti-cancer drugs. microRNAs (miRNAs) are a class of small, non-coding, RNA molecules that modulate gene expression post-transcriptionally. They are important regulator in normal biological process; however miRNAs deregulation has been observed in many different tumors and is involved in tumorigenesis. miRNAs may act as tumor suppressors or as oncogenes. Several studies on head and neck cancer demonstrated how aberrant expression of miRNAs is involved in proliferation, metastasis, chemoresistence, and radioresistance. In addition, miRNAs are excellent biomarker targets because they circulate stable in human body fluids and can be obtained with non-invasive methods. Moreover, miRNAs up and down regulation has been correlated with specific cancer phenotype (poor prognosis, aggressiveness and resistance to treatment), playing a role as prognostic biomarkers. This review summarizes current finding on miRNAs in head and neck cancer and their potential role as target for next drug therapy.

Active treatment given in the last weeks of life: poor quality cancer care or justifiable behavior?

PURPOSE: Chemotherapy near the end of life is frequently considered as an indicator of inappropriate aggressiveness. We were interested in revising our prescribing habits and in analyzing the reasons for offering active treatment to patients with advanced cancer. METHODS: We examined the electronic medical records of all the cancer patients died in the Italian Region of Valle d'Aosta in a 1-year period and extracted all the available clinical data. From the 350 deceased patients, we selected the 141 to whom active treatment had been given during the natural history of their disease. RESULTS: Among the patients undergoing any active treatment, the median number of days from the last administration to death was 75. Thirty-seven patients (26.2 %) had their last treatment administration during the 4 weeks before death and 20 (14.2 %) during the last 2 weeks. Fourteen patients (9.9 %) started treatment during the last 4 weeks. When the patients undergoing treatment in the last 4 weeks of life were compared with those subject to earlier withdrawal, only age and pretreatment were statistically significantly different. Most of the treatment choices were considered appropriate, and earlier treatment withdrawal could have been advised only in a minority of the cases. CONCLUSIONS: Our data were at the lower range when compared with the available literature. Uncertainties in prognostication and the possibility of response to treatment can justify chemotherapy prescriptions in selected cases. We suggest that the focus should move to the provision of adequate and timely supportive care.
