In the last decade, there has been increasing use of contralateral prophylactic mastectomy (CPM) in patients with unilateral breast cancer and ductal carcinoma-in-situ (DCIS) undergoing mastectomy. Although many factors have been proposed to explain this trend, the impact of breast reconstruction on CPM has not been studied. ⋯ Besides age, undergoing reconstructive surgery is the factor most strongly associated with CPM. This suggests that apart from risk reduction, the availability of and/or patient willingness to undergo breast reconstruction may influence the decision to undergo CPM.

Synchronous multiple small adenocarcinomas are detected more frequently than in the past; however, the genetic profile, treatment, and prognosis of patients remain unclear. For treatment decisions and prognostic applications, we evaluated epidermal growth factor receptor (EGFR), p53, and KRAS somatic mutations in synchronous multiple small lung adenocarcinomas. ⋯ Whether these tumors are different or the same clonal, sublobar resection of each lesion can achieve long-term DFS and is the treatment of choice for synchronous multiple small lung adenocarcinomas. Patients with lymph node metastasis are at risk of relapse and adjuvant chemotherapy is indicated.

Recently, a simple and easy complication prediction system, the surgical apgar score (SAS) calculated by three intraoperative parameters (estimated blood loss, lowest mean arterial pressure, and lowest heart rate), has been proposed for general surgery. In this study, we evaluated the predictability of the original SAS (oSAS) for severe complications after gastrectomy. In addition, the predictability of a modified SAS (mSAS) was evaluated, in which the cutoff value for blood loss was slightly modified. ⋯ The oSAS was not found to be a predictive factor for severe complications following gastrectomy in Japanese patients. A slightly modified SAS (i.e. the mSAS) is considered to be a useful predictor for the development of severe complications in elective surgery.

For lesions invading the middle hepatic vein (MHV) at caval confluence (CC) the mini-mesohepatectomy(MMH) was proposed.1 If the lesion is extended to the paracaval portion of segment 1(S1) in contact or invading the MHV a new procedure is proposed. ⋯ For tumors involving S1, S4s and/or S8 and infiltrating or in contact with the MHV at the CC, can be removed in a conservative manner by means of the herein described ''Liver Tunnel'' approach. The latter introduces a further step in favour of parenchyma-sparing policy for centrally located lesions with complex tumor-vessel relationship.
