Patients with colorectal peritoneal metastases who are not eligible for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) owing to extensive peritoneal disease have a poor prognosis. It was hypothesized that these patients may benefit from the addition of intraperitoneal irinotecan to standard palliative systemic chemotherapy. ⋯ Administration of 75 mg intraperitoneal irinotecan concomitantly with systemic FOLFOX-bevacizumab was safe and well tolerated. Intraperitoneal SN-38 exposure was high and prolonged. As oncological outcomes were promising, intraperitoneal administration of irinotecan may be a good alternative to other, more invasive and costly treatment options. A phase II study is currently accruing.

Lung cancer resection is associated with high rates of prolonged hospital stay. It is presumed that preconditioning with aerobic exercise can shorten the postoperative duration of hospital stay, but this has not yet been demonstrated in trials after lung cancer surgery. The aim of this study was to perform a RCT to determine whether Move For Surgery (MFS), a home-based and wearable technology-enhanced preconditioning program before lung cancer surgery, is associated with a lower incidence of prolonged hospital stay when compared to usual preoperative care. ⋯ MFS, a home-based and wearable technology-enhanced preconditioning program before lung cancer surgery, decreased the proportion of patients with a prolonged hospital stay. Registration number: NCT03689634 (http://www.clinicaltrials.gov).

Colon cancer in young patients is often associated with hereditary syndromes; however, in early-onset rectal cancer, mutations of these genes are rarely observed. The aim of this study was to analyse the features of the local immune microenvironment and the mutational pattern in early-onset rectal cancer. ⋯ Early-onset rectal cancer is rarely associated with common hereditary syndromes. The tumour microenvironment is characterized by a high frequency of mutations impairing the local immune surveillance mechanisms and low expression of immune editing-related genes. A constitutively low number of CD4 T cells associated with a high number of T regulators indicates an imbalance in the immune surveillance mechanisms.
