A multidisciplinary expert opinion on CINV and RINV, unmet needs and practical real-life approaches
Introduction: A range of combination chemotherapy regimens are currently used in clinical practice. However, international antiemetic guidelines often only categorize the emetogenic potential of single agents rather than the emetogenicity of combination chemotherapy regimens. To manage the nausea and vomiting induced by antineoplastic combinations, guidelines suggest antiemetics that are appropriate for the component drug with the highest emetogenic potential. Furthermore, antiemetic guidelines generally do not consider the influence of other factors, including individual patient characteristics, on the emetic effects of cancer treatments. Similarly, the emetogenic potential of radiotherapy is stratified only according to the site of radiation, while other factors contributing to emetic risk are overlooked. Areas covered: An Expert Panel was convened to examine unresolved issues and summarize the current clinical research on managing nausea and vomiting associated with combination chemotherapy and radiotherapy. Expert opinion: The panel identified the incidence of nausea and vomiting induced by multi-drug combination therapies currently used to treat cancer at different anatomic sites and by radiotherapy in the presence of other risk factors. Based on these data and the clinical experience of panel members, several suggestions are made for a practical approach to prevent or manage nausea and vomiting due to chemotherapy regimens and radiation therapy
Neoadjuvant strategies for pancreatic cancer.
Pancreatic cancer (PC) is the fourth cause of cancer death in Western countries, the only chance for long term survival is an R0 surgical resection that is feasible in about 10%-20% of all cases. Five years cumulative survival is less than 5% and rises to 25% for radically resected patients. About 40% has locally advanced in PC either borderline resectable (BRPC) or unresectable locally advanced (LAPC). Since LAPC and BRPC have been recognized as a particular form of PC neoadjuvant therapy (NT) has increasingly became a valid treatment option. The aim of NT is to reach local control of disease but, also, it is recognized to convert about 40% of LAPC patients to R0 resectability, thus providing a significant improvement of prognosis for responding patients. Once R0 resection is achieved, survival is comparable to that of early stage PCs treated by upfront surgery. Thus it is crucial to look for a proper patient selection. Neoadjuvant strategies are multiples and include neoadjuvant chemotherapy (nCT), and the association of nCT with radiotherapy (nCRT) given as either a combination of a radio sensitizing drug as gemcitabine or capecitabine or and concomitant irradiation or as upfront nCT followed by nRT associated to a radio sensitizing drug. This latter seem to be most promising as it may select patients who do not go on disease progression during initial treatment and seem to have a better prognosis. The clinical relevance of nCRT may be enhanced by the application of higher active protocols as FOLFIRINOX

(18)F-FDG-PET/CT in patients with breast cancer and rising Ca 15-3 with negative conventional imaging: A multicentre study
OBJECTIVES: Breast cancer is the second cause of death in women in Europe and North America. The mortality of this disease can be reduced with effective therapy and regular follow up to detect early recurrence. Tumor markers are sensitive in detecting recurrent or residual disease but imaging is required to customize the therapeutic option. Rising tumor markers and negative conventional imaging (US, X-mammography, CT and MR) poses a management problem. Our aim is to assess the role of (18)F-FDG-PET/CT in the management of post-therapy patients with rising markers but negative conventional imaging. MATERIALS AND METHODS: In the period from January 2008 to September 2009, 89 female patients with breast cancer who developed post-therapy rising markers (serum Ca 15-3 levels=64.8+/-16.3U/mL) but negative clinical examination and conventional imaging were investigated with (18)F-FDG-PET/CT. RESULTS: Tumor deposits were detected in 40/89 patients in chest wall, internal mammary nodes, lungs, liver and skeleton. The mean SUVmax value calculated in these lesions was 6.6+/-1.7 (range 3.1-12.8). In 23/40 patients solitary small lesion were amenable to radical therapy. In 7 out of these 23 patients a complete disease remission lasting more than 1 year was observed. CONCLUSIONS: (18)F-FDG-PET/CT may have a potential role in asymptomatic patients with rising markers and negative conventional imaging. Our findings agree with other studies in promoting regular investigations such as tumor markers and (18)F-FDG-PET/CT rather than awaiting the developments of physical symptoms as suggested by current guidelines since the timely detection of early recurrence may have a major impact on therapy and survival

Additional Value of FDG-PET/CT in Management of "Solitary" Liver Metastases: Preliminary Results of a Prospective Multicenter Study
The most common malignancy affecting the liver is metastasis from a wide variety of tumors, particularly those of gastrointestinal origin. Successful surgical removal of a solitary liver metastasis may significantly extend survival and optimal preoperative assessment in this regard is a mandatory prerequisite for proper patient selection. The addition of positron emission tomography/computed tomography (PET/CT) to other more conventional imaging procedures (e.g., ultrasound (US), CT, and magnetic resonance) has the potential to greatly improve the selection process by the combination of high-resolution anatomy afforded by CT directly combined with the functional scintigraphic map of intra- and extrahepatic lesions depicted by 2-deoxy-2-[F-18]fluoro-d-glucose (FDG)-PET. In this study, we assess the additional value of PET/CT in the management strategy of patients with solitary liver metastasis from colorectal and other cancers identified by conventional imaging methods.
We evaluated 43 consecutive patients (17 males, 26 females, mean age 53 +/- 6 years) with known solitary liver metastasis. This sample consisted of 18 patients with colorectal cancer, 15 with nonsmall cell lung cancer, six with breast carcinoma, and four ovarian cancers. In addition to contrast-enhanced CT and US, all patients were studied with FDG-PET/CT before surgery. PET/CT was performed within 3 weeks of the initial diagnosis and the scans were read by two experienced radiologists/nuclear medicine specialists blinded to the clinical data. A final diagnosis was obtained at surgery in 31 patients, by fine needle biopsy in five, and long-term clinical, biochemical, and follow-up imaging in seven patients.
In 12 out of 43 patients (28%), PET/CT resulted in restaging disease and a change in therapy. Twenty-two of 31 patients with confirmed solitary liver lesions (71%) were disease-free, eight of 31 (26%) developed a new recurrence, and one of 31 (3%) died from disease progression over a 17 +/- 6-month follow-up interval. Nine of 12 patients (75%) with multiple metastases demonstrated by FDG-PET/CT were alive with disease and three of 12 (25%) deceased due to disease progression (p < 0.01) over a 17 +/- 6-month follow-up interval.
The addition of FDG-PET/CT to the routine assessment of patients with liver metastasis has a significant impact on disease staging and selection of suitable candidates for solitary liver metastasis resection and outcome
