Worldwide, sentinel node biopsy (SNB) is the recommended staging procedure for stage I/II melanoma. Most melanoma guidelines recommend re-excision plus SNB as soon as possible after primary excision. To date, there is no evidence to support this timeframe. ⋯ Time interval from primary melanoma excision until SNB was no prognostic factor for MSS in this SNB positive cohort. This information can be used to counsel patients.

Randomized Controlled Trial
Male sexual dysfunction after rectal cancer surgery: Results of a randomized trial comparing mesorectal excision with and without lateral lymph node dissection for patients with lower rectal cancer: Japan Clinical Oncology Group Study JCOG0212.
We conducted a randomized controlled trial (JCOG0212) to determine whether the outcome of mesorectal excision (ME) alone for rectal cancer is not inferior to that of ME with lateral lymph node dissection (LLND). The present study focused on male sexual dysfunction after surgery. ⋯ LLND may not increase sexual dysfunction incidence after rectal cancer surgery. This incidence is associated with increased age. This trial is registered with ClinicalTrials.gov, number NCT00190541 and University Hospital Medical Information Network Clinical Trials Registry, number C000000034.

After resection of colorectal liver metastases (CLM), RAS mutations are associated with modest survival benefit and second-line chemotherapy confers limited hope for cure. ⋯ Among patients undergoing resection of CLM after second-line chemotherapy, RAS mutational status is an independent predictor of survival and outweighs other factors to select patients for liver resection.

Two-stage hepatectomy (TSH) is the present standard for multiple bilobar colorectal liver metastases (CLM), but 25-35% of patients fail to complete the scheduled procedure (drop-out). To elucidate if drop-out of TSH is a patient selection (as usually considered) or a loss of chance. ⋯ Drop-out of TSH could be a loss of chance rather than a criteria for patient selection. "Unselected" OSH patients had the same outcomes of selected patients who completed TSH. A complete resection is the main determinant of prognosis.

Diverse fractions of patients with locally advanced resectable rectal cancer receive neoadjuvant chemoradiotherapy (NACRT). NACRT is known to decrease physical fitness, an undesirable side effect. This pilot aimed to determine the feasibility and preliminary effectiveness of a supervised outpatient physical exercise training program during NACRT in these patients. ⋯ This pilot demonstrated that a supervised outpatient physical exercise training program for individual patients with locally advanced resectable rectal cancer during NACRT is feasible for a large part of the patients, safe and seems able to prevent an often seen decline in physical fitness during NACRT. A larger study into the cost-effectiveness of this approach is warranted.
