RESUMO

BACKGROUND/AIM: The KIAA1199 gene has been associated with cancer-cell proliferation, but its functions remain poorly studied. Here, we examined the clinical significance of the KIAA1199 mRNA levels in locally advanced gastric cancer (GC). Materials and Methods/Results: Using samples from 254 patients with stage II/III GC, we found significantly higher KIAA1199 levels in cancerous tissues compared to adjacent normal mucosa (ANM). There was no significant relationship between KIAA1199 expression and clinical features. Although overall survival rates (OSR) of patients, who underwent surgery did not correlate with KIAA1199 expression, patients who underwent adjuvant chemotherapy with S-1 and had high KIAA1199 levels displayed significantly lower OSR. KIAA1199 knock down (KIAA1199-KD) suppressed proliferation, invasiveness, and sensitivity of GC cells to 5-fluorouracil (5-FU). CONCLUSION: KIAA1199 expression appears to be a promising prognostic marker in patients with locally advanced GC, who underwent postoperative adjuvant chemotherapy with S-1. KIAA1199 may represent a novel target for GC pharmacotherapy.

RESUMO

Reports of recurrence after obturator hernia repair are few. We describe the case of an 89-year-old woman who presented to us with a thrice recurrent obturator hernia. She had undergone open non-mesh repair twice and then laparoscopic non-mesh repair. She was readmitted to our hospital 6 months after the laparoscopic repair. Manual reduction was successful, paving the way for elective transabdominal preperitoneal repair. During the endoscopic repair, surgical mesh was placed extraperitoneally over the hernia defect and then fixed to Cooper's ligament with absorbable tacks. The patient was discharged on postoperative day 2 without complications. In the 2 months that have passed since the surgery there has been no sign of recurrence, but the patient will be carefully followed up. Repair of a recurrent obturator hernia is technically challenging; however, the transabdominal preperitoneal approach seems to be reliable and safe.

RESUMO

A 65-year-old woman underwent iliocecal resection for cecal cancer. During post-operative follow-up, she was diagnosed with metastasis to the abdominal wall and a curative resection was performed. After 12 courses of adjuvant chemotherapy with a modified combination of folinic acid, 5-fluorouracil, and oxaliplatin (mFOLFOX6), recurrence was noted in the lung. A curative resection was successfully performed and she was subsequently treated with bevacizumab and a combination of folinic acid, 5-fluorouracil, and irinotecan (FOLFIRI). One year after surgical resection, recurrence in the remnant lung was diagnosed. Because of the KRAS mutation, she could not be treated with anti-epidermal growth factor antibodies. The metastatic lung tumor continued to enlarge. Therefore, we selected regorafenib as third-line chemotherapy. After treatment with regorafenib, the size of the target lesion decreased significantly.

RESUMO

A case of mucinous adenocarcinoma arising on a long-standing anorectal fistula is described. A 60-year-old man with a long history of mucinous discharge, pain and perianal induration underwent a biopsy of the external opening of the fistula that showed a mucinous infiltrating adenocarcinoma. Due to the large size of the tumor and the fact that it had extended into the surrounding tissue, preoperative radiotherapy was performed. Radiotherapy was given with 40 Gy in 25 fractions for 5 weeks through posterior and bilateral portals. After radiotherapy the tumor was markedly shrunk and the serum level of carcinoembryonic antigen was also improved. Abdominoperineal resection was performed 8 weeks after the termination of radiotherapy. Histological examination of the resected specimen revealed that the invasion of the tumor remained within the sphincter muscle and that no cancer cells were present on the surgical margin. The histological effect of radiotherapy was judged as grade 1b. This treatment can result in downstaging and R0 resection, which also has a possibility to prevent local recurrence. This case suggests that preoperative radiotherapy may play an important role in the definitive treatment of locally advanced perianal mucinous adenocarcinoma.

RESUMO

A 59-year-old man with type 3 gastric cancer(signet-ring cell carcinoma)underwent simple laparotomy because of peritoneal dissemination.S -1/CDDP was started.Since the icterus of Grade 2 had appeared after 2 courses, S-1 and biweekly paclitaxel combination chemotherapy was started as second-line treatment.Throughout treatment, there was no adverse event, and this regimen was continued for 14 courses(25 months).He died 32 months after his first visit.S -1/PTX may play an important role as second-line chemotherapy for patients with unresectable advanced gastric carcinoma.

RESUMO

We report a schwannoma of the gallbladder in a 58-year-old man who was diagnosed as cholecystolithiasis. He presented with recurrent episodes of abdominal pain in the right upper quadrant. The abdominal computed tomography scan and ultrasonography revealed stones about 15 mm in diameter in the gallbladder. Under the diagnosis of cholecystolithiasis, laparoscopic cholecystectomy was performed. The resected specimen showed chronic cholecystitis and no suspicion of neoplasm. Pathological examination revealed that the tumor consist of spindle cells without atypical appearance at small area of fundus. Immunohistologically, tumor cells were positive for S-100 protein and negative for alpha-SMA and c-kit, the lesion was diagnosed as schwannoma.
