The prognosis for pancreatic cancer patient is very poor. Patients with locally advanced disease have a median survival time of 8 to 12 months, and patients with distant metastases have significantly worse outcomes, with a median survival time of only 3 to 6 months. Approximately 30% of patients with pancreatic cancer present with locally advanced disease defined as unresectable pancreatic cancer without evidence of distant metastatic disease. Primary treatment options in locally advanced pancreatic cancer include chemotherapy and radiotherapy. Here, we reported a patient with locally advanced pancreatic cancer who does not want further chemotherapy because of chemotherapy induced nausea and vomiting. Irreversible electroporation was performed. Irreversible electroporation was well tolerated in this case, and may be a therapeutic modality for selected patients with locally advanced pancreatic cancer.

Pancreatic cancer treatment has advanced. In particular, effective chemotherapy regimen development has fundamentally altered the therapeutic concept and strategy for pancreatic cancer treatment. Consequently, the prognosis of patients with pancreatic cancer has gradually improved. Conversion surgery for locally advanced pancreatic cancer may offer long-term survival or even a full recovery in some individuals. In contrast, metastatic pancreatic cancer has long been considered a surgical contraindication because aggressive surgical resection of the metastatic lesions does not prolong patient survival. Unexpectedly positive benefits of anticancer therapy in recent clinical experience were observed even with metastatic pancreatic cancer. To date, little evidence presented the success of surgical resection for metastatic pancreatic cancer treatment in such rare cases. However, hope and concern are growing that surgical intervention, even in patients with metastatic cancer, may result in favorable outcomes. Several studies suggested different surgical intervention effects depending on metastasis sites and patterns. Thus, this review summarizes the current status of surgery in the multidisciplinary treatment of oligometastatic pancreatic cancer and discusses future perspectives.

Purpose: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. Materials and Methods: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. Results: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Conclusion: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

Background: Despite recent advances in first-line chemotherapy for advanced pancreatic cancer, standard treatment after the failure of initial chemotherapy has not been established. Hence, we aimed to retrospectively analyze the clinical characteristics and outcomes of second-line chemotherapy in patients with advanced pancreatic cancer. Methods: We reviewed the clinical data of patients with advanced pancreatic cancer who underwent palliative chemotherapy at Kosin University Gospel Hospital between January 2013 and October 2020. Results: Among 366 patients with advanced pancreatic cancer who had received palliative chemotherapy, 104 (28.4%) underwent at least one cycle of second-line chemotherapy. The median age of the patients at the time of initiating second-line treatment was 62 years (interquartile range, 57-62 years), and 58.7% (61 patients) of them were male. The common second-line chemotherapy regimens were 5-fluorouracil (FU) plus leucovorin, irinotecan, and oxaliplatin (33 patients, 31.7%); gemcitabine/nab-paclitaxel (29, 27.9%), gemcitabine±erlotinib (13, 12.5%); and oxaliplatin and 5-FU/leucovorin (12, 11.5%). The median overall survival (OS) and progression-free survival were 6.4 months (95% confidence interval [CI], 4.5-8.6 months) and 4.5 months (95% CI, 2.7-6.3 months), respectively. In a multivariate analysis, poor performance status (PS) (hazard ratio [HR], 2.247; p=0.021), metastatic disease (HR, 2.745; p=0.011), and elevated carcinoembryonic antigen (CEA) levels (HR, 1.939; p=0.030) at the beginning of second-line chemotherapy were associated with poor OS. Conclusion: The survival outcome of second-line chemotherapy for advanced pancreatic cancer remains poor. However, PS, disease extent (locally advanced or metastatic), and CEA level may help determine patients who could benefit from second-line treatment.

Pancreatic cancer has a very poor prognosis. Complete surgical resection remains the only current curative treatment. Locally advanced pancreatic cancer (LAPC) is considered as unresectable because of involvement of celiac and/or mesenteric vessels. The treatment of LAPC is a challenge. Current guidelines suggest systemic therapy. However, the majority of patients will never experience conversion to surgical resection. Thus, in these patients, ablation is an alternative therapy for local control, which causes local destruction while ideally avoiding injury to surrounding healthy tissue. Irreversible electroporation (IRE) is an energy delivery system, effective in ablating tumors by inducing irreversible membrane destruction of cells. IRE demonstrated to be safe in previous studies. However, it is not free from complications, even serious. Here, we reported two cases of the IRE in LAPC patients.

Objective: To explore improved treatment by retrospectively comparing survival time of gemcitabine-based concurrent chemoradiotherapy (GemRT) versus chemotherapy (Gem) alone in patients with locally advanced pancreatic cancer (LAPC). Methods: From January 2005 to June 2010, 56 patients with LAPC from Subei People's Hospital were treated either with Gem (n=21) or GemRT (n=35). Gem consisted of 4-6 cycles gemcitabine alone (1000 mg/m2 on Days 1, 8, 15, 28-day a cycle). GemRT consisted of 50.4Gy/28F radiotherapy with concurrent 2 cycles of gemcitabine (1000 $mg/m^2$ on days of radiation 1, 8, 15, 21-day a cycle). Radiation was delivered to the gross tumor volume plus 1-1.5 cm by use of a three-dimensional conformal technique. The follow-up time was calculated from the time of diagnosis to the date of death or last contact. Kaplan-Meier methodology wes used to evaluate survival. Results: Patient characteristics were not significantly different between treatment groups. The disease control rate and the objective response rate of GemRT versus Gem was 97.1% vs 71.4%, 74.3% vs 38.1%. The overall survival (OS) was significantly better for GemRT compared to Gem (median 13 months versus 8 months; 51.4% versus 14.3% at 1 year, respectively). Conclusion: Radiation therapy at 50.4Gy with 2 concurrent cycles of gemcitabine results in favorable rates of OS. Concurrent chemoradiotherapy should be the first choice for patients with LAPC.

목 적: 국소적으로 진행된 절제 불가능한 췌장암에서 방사선치료 및 동시화학방사선치료에 대한 치료성적과 예후 인자를 후향적으로 분석하였다. 대상 및 방법: 1994년 1월부터 2008년 8월까지 절제 불가능한 국소 진행된 췌장암으로 진단받은 환자 중 30 Gy 이상의 방사선치료를 받은 51명을 대상으로 후향적 분석을 시행하였다. AJCC 병기에 따라 IIA부터 III까지의 환자를 대상으로 하였다. 방사선치료는 중앙값 39 Gy를 조사하였고 38명에서 항암화학요법을 병행하였는데 cisplatin, 5-FU, gemcitabine을 단독 혹은 병합하여 사용하였다. 결 과: 추적관찰기간은 2~40개월(중앙값 8개월)이었다. 전체 환자의 중앙생존기간, 1년, 2년 생존율은 각각 7개월, 15.7%, 5.9%이었다. 예후에 영향을 미치는 인자로 치료 전 CA19-9, 전신수행상태, 항암화학요법의 종류가 통계적인 유의성을 보여주었다. 동시화학방사선치료군의 중앙생존기간은 8개월, 방사선단독치료군은 6개월이었다. Gemcitabine 단독 및 gemcitabine을 포함한 조합으로 치료받은 환자의 중앙생존기간은 10개월로 방사선치료만 받은 환자와 유의한 차이를 보여주었다. 재발여부를 확인할 수 있었던 23명의 환자 중 18명에서 원격전이가 발견되었고 4명의 환자에서 림프절전이가 있었다. 부분관해 혹은 안정병변을 보였던 환자 중 원발병소의 크기가 커진 환자가 14명이었다. 원격전이까지의 기간을 확인할 수 있었던 18명의 환자를 대상으로 CA19-9과의 상관관계를 분석한 결과, 치료 전 정상 CA19-9인 환자의 원격전이까지의 중앙기간이 20개월인 반면 200 U/ml 이상인 경우에는 2개월에 불과하였다. 결 론: 절제 불가능한 국소 진행된 췌장암 환자에서 gemcitabine과 방사선치료의 병합요법이 생존율 증가에 효과가 있었다. 또한 치료 전 CA19-9의 상승 정도가 환자의 예후 및 치료방향을 결정하는데 도움이 될 것으로 생각된다.
