RESUMEN
BACKGROUND/AIM: Additional primary malignancy (APM) risk is increasing with improved prognosis of cancer survivors. In order to clarify risk factors and patients susceptible to develop APMs, we investigated the clinical features, prognosis, and approaches for diagnosis and treatment in these patients. PATIENTS AND METHODS: Among 874 patients newly diagnosed with gastrointestinal tract (GIT) or hepato-biliary-pancreatic (HBP) cancers between 2011 and 2014, 124 with a synchronous and/or metachronous APM were identified. Patient characteristics, time interval between the malignancies, clue to detect APMs, treatment approaches, and prognosis were investigated. RESULTS: Patients with APMs were older and predominantly male. Half of the metachronous APMs were detected within 3 years after the first primary malignancy (PM). The main clue to detect synchronous and metachronous APMs was preoperative screening for current PM, and follow-up of prior PM, respectively. There was no significant difference in the overall survival between colon cancer patients with or without APMs. CONCLUSION: Multiple PMs were present in 14.2% of patients. Male and old age were identified to be risk factors for APM. Pre-operative screening and post-operative regular follow-ups are important for detecting synchronous or metachronous APMs.

BACKGROUND: Most groin masses are first suspected to be groin hernias. More than 80% of bulging groin lesions are reportedly diagnosed as hernias by ultrasonography. Establishment of the correct diagnosis of hernia among all differential diagnoses is not easy. We herein describe a very rare case of groin eosinophilic funiculitis that presented as an irreducible groin hernia. CASE PRESENTATION: A 59-year-old man presented to our hospital with suspicion of a right groin hernia. He had a 1-week history of a painful right groin tumor. The tumor was about 4 cm without skin redness or warmth, irreducible even in the supine position, and associated with mild tenderness. Enhanced computed tomography showed that the mass seemed to be connected to the intra-abdominal structures. With time, the patient's pain did not increase, the inflammatory response did not worsen, and no ischemic signs were observed by enhanced computed tomography. Therefore, we diagnosed the tumor as an irreducible but not incarcerated hernia and performed elective surgery. Intraoperative examination revealed no hernia sac, and a 4-×3-cm tumor was observed around the spermatic cord. A malignant tumor was not completely ruled out. High orchiectomy was performed after consultation with the urologists. Pathological examination of the tumor showed no malignant features, and the final diagnosis was eosinophilic funiculitis with massive inflammatory changes and eosinophil invasion. CONCLUSION: Eosinophilic funiculitis is very rare; only three cases have been reported to date. We should always consider unusual causes of groin masses during a surgical approach to hernia-like lesions.
RESUMEN
AIM: This study was planned to evaluate the efficacy and safety of preoperative capecitabine and oxaliplatin (XELOX) without radiation in patients with locally advanced lower rectal cancer. PATIENTS AND METHODS: Patients with clinical stage II/III lower rectal cancer underwent three cycles of XELOX followed by radical surgery. The primary end-point was the R0 resection rate. RESULTS: Thirty-one patients were recruited between February 2012 and August 2014. The completion rate of neoadjuvant chemotherapy was 96.5% among the 29 patients who received it; the remaining two refused chemotherapy and underwent immediate surgery. Grade 3-4 adverse events occurred in nine patients (31%). All 29 patients who received chemotherapy underwent radical resection. The R0 resection rate was 96.5% among these 29 patients. Pathological complete responses were achieved in three patients (10.3%) and downstaging occurred in 13 (44.8%). CONCLUSION: This pilot study found that neoadjuvant XELOX for locally advanced lower rectal cancer is feasible and safe. This neoadjuvant treatment improved resection margin status.
