Factors Affecting Sentinel Node Metastasis in Thin (T1) Cutaneous Melanomas: Development and External Validation of a Predictive Nomogram.

PURPOSE: Thin melanomas (T1; ≤ 1 mm) constitute 70% of newly diagnosed cutaneous melanomas. Regional node metastasis determined by sentinel node biopsy (SNB) is an important prognostic factor for T1 melanoma. However, current melanoma guidelines do not provide clear indications on when to perform SNB in T1 disease and stress an individualized approach to SNB that considers all clinicopathologic risk factors. We aimed to identify determinants of sentinel node (SN) status for incorporation into an externally validated nomogram to better select patients with T1 disease for SNB. PATIENTS AND METHODS: The development cohort comprised 3,666 patients with T1 disease consecutively treated at the Istituto Nazionale Tumori (Milan, Italy) between 2001 and 2018; 4,227 patients with T1 disease treated at 13 other European centers over the same period formed the validation cohort. A random forest procedure was applied to the development data set to select characteristics associated with SN status for inclusion in a multiple binary logistic model from which a nomogram was elaborated. Decision curve analyses assessed the clinical utility of the nomogram. RESULTS: Of patients in the development cohort, 1,635 underwent SNB; 108 patients (6.6%) were SN positive. By univariable analysis, age, growth phase, Breslow thickness, ulceration, mitotic rate, regression, and lymphovascular invasion were significantly associated with SN status. The random forest procedure selected 6 variables (not growth phase) for inclusion in the logistic model and nomogram. The nomogram proved well calibrated and had good discriminative ability in both cohorts. Decision curve analyses revealed the superior net benefit of the nomogram compared with each individual variable included in it as well as with variables suggested by current guidelines. CONCLUSION: We propose the nomogram as a decision aid in all patients with T1 melanoma being considered for SNB.

[Turn-over of non-tenured public health research personnel in an Italian public research institute (IRCCS).] / Il turn-over del personale con contratti di lavoro flessibili o borse di studio dedicato alla ricerca sanitaria in un IRCCS pubblico italiano.

BACKGROUND: The objective is to show variations in the number of non-tenured personnel (NTP) in a public health research centre (IRCCS) between 30th June 2016 and 31st December 2017. In this time interval, the issue of NTP was at the centre of governmental discussions. METHODS: Data collection was performed from CVs and scientific publications of NTP working at the Fondazione IRCCS Istituto Nazionale dei Tumori (INT). We compared the characteristics of NTP entering or leaving INT and those of NTP who remained in the considered time interval. RESULTS: NTP in INT counted 465 members of staff at 30th June 2016 and 472 at 31st December 2017. 75% of these works in the research. 26% of NTP left INT and their position resulted entirely substituted by other NTP. NTP staff who left are mainly aged under 40 and show fewer publications than those who stayed. Newly acquired NTP are younger and show a fewer number of publications compared to the personnel who left. CONCLUSIONS: 1 out of 4 NTP members of staff moved to a new job during a period in which the uncertain future of NTP research staff was under the spotlight. It appears that IRCCS are progressively being identified as suitable for hands-on, post university internships from which researchers would then choose to move, in search of a new job in public or private centres, with a consequent decline of IRCCS' role in health research.

Variables affecting evaluation and publication of oncology case reports: a systematic analysis.

BACKGROUND: Studies on factors affecting editorial decisions of scientific journals are scarce. In this study, we focused on case reports submitted to oncology journals and analyzed whether their nature or other relevant variables affected the chances of their acceptance. METHODS: We analyzed case reports submitted to 2 oncology journals: Tumori Journal and The International Journal of Biological Markers, and split them into 3 predefined groups: those (a) describing rare or unusual presentation of diseases, (b) describing the side effects of an intervention or (c) describing the success of a novel intervention. Publication status was retrospectively retrieved from the submission system, and acceptance rates were calculated taking into account other variables including geographic location of corresponding author. RESULTS: A total of 326 case reports were suitable for analysis. The acceptance rate was 35.4% for group (a), 27.9% for group (b), 19.6% for group (c) (p = 0.01). After correcting for other variables, the odds ratio (OR) of being accepted for group (c) was 0.58 (95% CI, 0.33-1.00) compared with the other groups combined. There was a highly significant difference of acceptance rates between manuscripts with authors coming from developed vs. developing countries that remained significant (OR = 5.94; 95% CI, 3.05-10.09) after correcting for multiple variables. CONCLUSIONS: The nature of a case report in oncology may affect acceptance rate, with case reports describing successful approaches or side effects of treatment being accepted with a higher frequency then case reports describing a rare clinical or diagnostic scenario. Also, works coming from developed countries are accepted significantly more frequently than case reports coming from developing countries.

National Cancer Information Service in Italy: an information points network as a new model for providing information for cancer patients.

The international literature data report that good information and communication are fundamental components of a therapeutic process. They contribute to improve the patient-health care professional relationship, to facilitate doctor-patient relationships, therapeutic compliance and adherence, and to the informed consent in innovative clinical trials. We report the results of a multicentric national initiative that developed a 17-information-structure network: 16 Information Points located in the major state-funded certified cancer centers and general hospitals across Italy and a national Help-line at the nonprofit organization AIMaC (the Italian oncologic patients, families and friends association), and updated the already existing services with the aim to create the National Cancer Information Service (SION). The project is the result of a series of pilot and research projects funded by the Italian Ministry of Health. The Information Service model proposed is based on some fundamental elements: 1) human interaction with experienced operators, adequately trained in communication and information, complemented with 2) virtual interaction (Help line, Internet, blog, forum and social network); 3) informative material adequate for both scientific accuracy and communicative style; 4) adequate locations for appropriate positioning and privacy (adequate visibility); 5) appropriate advertising. First results coming from these initiatives contributed to introduce issues related to "Communication and Information to patients" as a "Public Health Instrument" to the National Cancer Plan approved by the Ministry of Health for the years 2010-2012.
