RÉSUMÉ

Background/Aims@#There has been growing evidence on the utility of neoadjuvant FOLFIRINOX in borderline resectable (BR) or locally advanced (LA) pancreatic cancer. However, factors predicting survival in these patients remain to be identified, and we aimed to identify these prognostic factors. @*Methods@#Between January 2013 and April 2017, patients with BR or LA pancreatic cancer who received FOLFIRINOX as their initial treatment were identified. Demographic data and clinical outcomes, including the chemotherapy response, conversion to resection, and survival, were reviewed. @*Results@#A total of 117 patients with BR (n=39) or LA (n=78) pancreatic cancer were included. Of these patients, 29 (24.8%) underwent curative surgery, and R0 resection was achieved in 21 patients (72.4%). The median progression-free survival and overall survival time of all patients were 11.6 and 19.0 months, respectively. In resected patients, the median relapse-free survival and overall survival times were 14.8 and 28.6 months, respectively. In the multivariate Cox model, the lowest level of serum carbohydrate antigen 19-9 (CA 19-9) and resection after FOLFIRINOX were independent factors for improved overall survival. In the subgroup analysis of patients with initial 18 F-fluorodeoxyglucose-positron emission tomography (FDG-PET) images, the maximum standardized uptake value (SUVmax) of the pancreatic mass was also shown as an independent factor for improved overall survival. @*Conclusions@#In patients with BR or LA pancreatic cancer, FOLFIRINOX is a valuable neoadjuvant treatment that enables curative surgery in approximately one-quarter of patients and significantly improves overall survival. In these patients, the prognosis can be estimated using the lowest level of serum CA 19-9, operative status, and initial FDG-PET SUVmax.

RÉSUMÉ

BACKGROUND/AIMS: Recurrent pyogenic cholangitis (RPC) is a chronic progressive disease frequently accompanied by cholangiocarcinoma (CCA). This study aimed to investigate the natural course of RPC and identify factors associated with CCA. METHODS: From January 2005 to December 2016, 310 patients diagnosed with RPC at Seoul National University Hospital were included. Complications and management during follow-up were recorded. CCA-free probability was estimated by Kaplan-Meier method, and risk factors associated with CCA were analyzed using log-rank test and Cox’s proportional hazard regression model. RESULTS: Mean age at diagnosis was 59.1±10.9 years and mean follow-up duration was 84.0±64.1 months. An intrahepatic duct stone was found in 253 patients (81.6%). Liver atrophy was identified in 185 patients (59.7%) and most commonly located at the left lobe (65.4%). Acute cholangitis, liver abscesses, cirrhotic complications, and CCA developed in 41.3%, 19.4%, 9.7%, and 7.4%, respectively. During follow-up, complete resolution rate after hepatectomy, biliary bypass surgery, and choledocholithotomy with T-tube insertion reached 82.3%, 55.2%, and 42.1%, respectively. None of the patients who maintained complete resolution by the last follow-up day developed CCA. In univariate analysis, female, both-sided intrahepatic duct stones, and liver atrophy at any location were associated with increased risk of CCA. Multivariate analysis revealed that both-sided atrophy significantly increased risk of CCA (hazard ratio, 4.56; 95% confidence interval, 1.48 to 14.09; p=0.008). In 21 patients who developed intrahepatic CCA, tumor was located mostly in the atrophied lobe (p=0.023). CONCLUSIONS: In RPC patients, acute cholangitis, liver abscess, cirrhotic complications, and CCA frequently developed. Both-sided liver atrophy was a significant risk factor for developing CCA.

RÉSUMÉ

We report two cases of patients with unresectable pancreatic cancer treated with neoadjuvant chemotherapy and surgical resection. In the first case, main mass was located at the neck of the pancreas, encasing superior mesenteric artery and peritoneal seeding was suspected. In the second case, main mass was located at the body of pancreas and superior mesenteric artery was encased. Both patients received FOLFIRINOX chemotherapy regimen, consisting of 5-FU, folinic acid, irinotecan and oxaliplatin. In both cases, tumor size decreased and vascular involvement regressed in response to chemotherapy. After subsequent chemoradiation therapy, both patients underwent surgical resection with negative resection margin. The pathological stages were ypT1cN0 and ypT1aN0, respectively. Both patients received postoperative adjuvant chemotherapy with 6 cycles of 5-FU/folinic acid and remained without evidence of disease for more than 6 months after the surgery.

RÉSUMÉ

Gallbladder cancer is the most common malignancy of the biliary tract and carries very poor prognosis. Surgery is an only curative modality of treatment in the gallbladder cancer. However, as most of the gallbladder cancers are diagnosed at advanced stages, surgery can be attempted in a very limited number of patients. In advanced stage, treatment option is confined to a palliative systemic chemotherapy, and biliary decompression is needed when cholangitis is suspected. We report a case of 49-year-old patient with metastatic gallbladder cancer treated with successful curative resection after several courses of palliative chemotherapy and biliary decompression.

RÉSUMÉ

BACKGROUND/AIMS: The combination of nab-paclitaxel and gemcitabine (nab-P/Gem) is widely used for treating meta-static pancreatic cancer (MPC). We aimed to evaluate the therapeutic outcomes and prognostic role of treatment-related peripheral neuropathy in patients with MPC treated with nab-P/Gem in clinical practice. METHODS: MPC patients treated with nab-P/Gem as the first-line chemotherapy were included. All 88 Korean patients underwent at least two cycles of nab-P/Gem combination chemotherapy (125 and 1,000 mg/m2, respectively). Treatment-related adverse events were monitored through periodic follow-ups. Overall survival and progression-free survival were estimated by the Kaplan Meier method, and the Cox proportional hazards regression linear model was applied to assess prognostic factors. To evaluate the prognostic value of treatment-related peripheral neuropathy, the landmark point analysis was used. RESULTS: Patients underwent a mean of 6.7±4.2 cycles during 6.3±4.4 months. The median overall survival and progression-free survival rates were 14.2 months (95% confidence interval [CI], 11.8 to 20.3 months) and 8.4 months (95% CI, 7.1 to 13.2 months), respectively. The disease control rate was 84.1%; a partial response and stable disease were achieved in 30 (34.1%) and 44 (50.0%) patients, respectively. Treatment-related peripheral neuropathy developed in 52 patients (59.1%), and 13 (14.8%) and 16 (18.2%) patients experienced grades 2 and 3 neuropathy, respectively. In the landmark model, at 6 months, treatment-related peripheral neuropathy did not have a significant correlation with survival (p=0.089). CONCLUSIONS: Nab-P/Gem is a reasonable choice for treating MPC, as it shows a considerable disease control rate while the treatment-related peripheral neuropathy was tolerable. The prognostic role of treatment-related neuropathy was limited.
