This retrospective study aimed to determine prognostic factors associated with postrecurrence survival of completely resected non-small cell cancer patients with postoperative recurrence. ⋯ Poor ECOG PS, shorter time from initial surgery to recurrence, and increasing number of initial recurrent regions are associated with poor prognosis after recurrence. When the number of recurrent lesions is limited, intensive local treatment with curative intent should be applied for achieving long-term postrecurrence survival.

Positive resection margins are amongst the strongest predictors of cancer-related mortality for adenocarcinoma of the stomach and esophagus. Although intraoperative pathology consultation with frozen section of margins can predict final permanent section pathology, the accuracy of this approach is not known. We sought to determine the diagnostic accuracy of frozen section margin analysis in esophagogastric adenocarcinoma and the impact that it had on surgical therapy. ⋯ Although very specific, negative results on frozen section require greater caution when signet ring cells are present. For esophagogastric adenocarcinoma, frozen section alters management and may increase the rate of complete resection.

Management of gastrointestinal stromal tumors (GISTs) has been transformed with tyrosine kinase inhibitors (TKIs). While data on optimal duration of adjuvant imatinib remains elusive, guidelines for administration of neoadjuvant TKIs remain unknown. ⋯ Neoadjuvant TKIs can be effectively used for the treatment of primary and recurrent/metastatic GIST. While duration of neoadjuvant therapy, KIT mutation status, and the need for multivisceral resection can help to predict higher risk for recurrence, progression on neoadjuvant TKIs can aid in selection of patients with recurrent/metastatic disease for surgical resection.

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.
