On the same principle than total mesorectal excision in rectal cancer, the effect of complete mesocolic excision on short and long-term outcomes is actually evaluated for colonic adenocarcinoma. This method, usually performed for left colectomy, offers a surgical specimen of higher quality, with a larger number of lymph nodes harvested. For right colectomy, surgical specifications make it less common complete mesocolic excision and conventional surgery offer comparable outcomes, as regards to postoperative morbidity and mortality rates. ⋯ On oncologic outcomes, only two studies report a higher free-disease survival after complete mesocolic excision. Then, there is evidence that complete mesocolic excision offers a higher rate of specimen with extensive lymph node resection, without increased morbidity rate. However, there is limited evidence that it leads to improve long-term oncological outcomes.

Observational Study
[Prognosis prediction of febrile neutropenia by MASCC score: A retrospective study].
The score of the MASCC, by means of clinical criteria, estimates the risk of serious complications in patients with neutropenic fever induced by chemotherapy. ⋯ This analysis suggests that the criteria of the MASCC are not always enough to thoroughly identify which patients were at risk of complications or could be treated through outpatient management. By better taking into account the comorbidities and tumoral stage, a better selection of the patients who are likely to receive an ambulatory treatment could be made. To date, hospitalization remains frequently necessary in neutropenic fevers, at least in its initial steps, and the place of the general practitioner remains to be better defined.

Chemotherapy with docetaxel has remained a cornerstone of second-line treatment for more than 15 years, but it is associated with an unfavorable safety profile. Recently, the results of 2 randomized phase III trials assessing nivolumab in lung cancer, Check-Mate-017 and Check- Mate-057, have deeply changed our current clinical practice and open the debate for further improvements in the clinical care of lung cancer. This paper explores the recent findings about nivolumab in the second-line setting and discusses future directions for nivolumab and other immune Oncology drugs.

ANTI-PD1 ROLE IN TREATMENT OF CUTANEOUS MELANOMA: The treatment of metastatic melanoma dramatically changed over the last years. Two therapeutic revolutions emerged in parallel, targeted anti-BRAF and anti-MEK therapies, for patients BRAFV600 mutated and immunotherapy with immune checkpoint blockers using anti-CTLA-4 then anti-PD1 monoclonal antibodies. Indeed, melanoma immunotherapy was a golden objective for many years but in spite of important efforts using cytokines (interferon, interleukin) and different vaccine approaches no objective improvement of patients 'prognosis was obtained. ⋯ Two molecules, pembrolizumab and nivolumab were recently approved in monotherapy, for metastatic melanoma. Several questions remain unresolved: the respective indications of anti-PD1 and targeted therapies in first line therapy in patients with BRAF mutant melanoma, the benefit of combining immunotherapy with radiotherapy or with targeted therapies, the optimal treatment duration, and the benefit of the anti-PD1 in the adjuvant setting. The combination of ipilimumab and nivolumab, recently approved by the FDA but not yet in Europ, shows an improvement of the objective response rates (50-57%) and progression free survival compared with nivolumab but is associated with an higer incidence of serious adverse events (more than 50%).
