OBJECTIVE: To study the therapeutic value of cryosurgery with combination of (125)iodine seed implantation for locally advanced pancreatic cancer. METHODS: Thirty-eight patients with locally advanced pancreatic cancer were enrolled in this study. The diagnosis was confirmed by pathology in 31 patients. Ten patients had metastases of the peripancreatic lymph node and eight had liver metastases. The therapy included cryosurgery, which was performed intra-operatively or percutaneously under guidance of ultrasound and/or computed tomography (CT), and (125)iodine seed implantation, which was performed during cryosurgery process or post-cryosurgery under the guidance of ultrasound and/or CT. RESULTS: Eleven patients received intra-operative cryosurgery and 27 received percutaneous cryosurgery. Fourteen patients underwent two procedures of cryosurgery and three underwent three procedures of cryosurgery. (125)Iodine seed implantation was performed during the freezing procedure in 29 patients and within 3-7 days after cryosurgery in nine patients under ultrasound and CT guidance. Fifteen patients, of whom 13 had metastases of peripancreatic lymph nodes or liver received regional chemotherapy. At 3 months after therapy, a CT follow-up was performed to estimate the tumor response to therapy. Most of the patients had varying degrees of tumor necrosis. A complete response of the tumor was seen in 23.6% of patients, a partial response in 42.1%, stable disease in 26.3% and progressive disease in 7.9%. The adverse effects associated with cryosurgery mainly included pain of the upper abdomen and increased serum amylase activity. Acute pancreatitis was seen in five patients, one of whom presented a severe type of pancreatitis. During the followed-up of a median of 16 months (range of 5-37) median overall survival was 12 months, 19 patients (50.0%) survived for 12 months or longer and four survived for 24 months or longer. CONCLUSION: As it is far less invasive than conventional pancreas resection and entails a low rate of adverse effects, cryosurgery should be the choice modality for most patients with locally advanced pancreatic cancer. (125)Iodine seed implantation can destroy residue survival cancer cells after cryosurgery. Hence, combination of both modalities has a complementary effect. 相似文献

OBJECTIVE: Collision cancers are malignancies in the same organ or anatomical site that comprises at least two different tumor components, with no mixed or transitional area between two components. Collision cancers are very rare in the pancreas and periampullary region. The aim of this study was to analyze the clinical and pathological features and prognosis of collision cancer in the pancreas and periampullary region. METHODS: Patients with collision cancers of the pancreas and periampullary region ( n= 10) who had undergone radical surgery were retrospectively studied. Their clinical and pathological features were summarized and the prognostic data were compared with patients with pancreatic adenocarcinomas who underwent radical surgery ( n= 87) and with patients with pancreatic or periampullary malignancies who underwent palliative surgery ( n= 89). RESULTS: Compared with other cancers at these sites, collision cancer presents no specific clinical features. However, the median survival period of patients with such malignancies was only 10.0 months, which was much less than those with pancreatic adenocarcinomas who underwent radical surgery (27.0 months) and those who received a palliative operation (20.9 months) only. CONCLUSION: Collision cancers of the pancreas and periampullary region are difficult to diagnose preoperatively. Their prognosis is poor even after radical resection and adjuvant chemotherapy were given. 相似文献

The aim of this study was to assess the efficacy and prognostic factors of definitive radiochemotherapy (RCT) for inoperable esophageal cancer. Between 1995 and 2005 all patients with inoperable esophageal cancer that underwent concurrent RCT were included in this retrospective study. Conventional computed tomography-based treatment planning as well as 3D-conformal radiotherapy (RT) was used. Maximum radiotherapy dose was 63 Gy. Chemotherapy consisted of cisplatin (20 mg/m(2) d1-5 and 29-33) and 5-FU (650-1000 mg/m(2) d1-5 and 29-33). Patients not suitable for RCT received radiotherapy alone. Toxicity was measured according to common toxicity criteria (CTC). Two hundred three consecutive patients with inoperable esophageal cancer that received definitive therapy were identified in this time period (160 with squamous cell carcinoma and 43 with adenocarcinoma). The 2-year overall survival probability was 21.2% whereas the progression-free survival at 2 years was 13.8% for all patients. In the univariate analysis, type of histology, T-stage, N-stage, application of chemotherapy, and the radiation dose were significantly correlated with overall/progression-free survival. Moreover, multivariate analysis revealed an independent prognostic impact for N-stage, radiation dose, and concurrent chemotherapy. Definitive RCT is an important palliative treatment option for patients with inoperable esophageal cancer. N-stage, radiation dose, and concurrent chemotherapy are important prognostic factors for survival. 相似文献

Background/PurposeWe aimed to investigate predictors of survival in patients with resectable locally invasive pancreatic cancer.MethodsThe patient cohort consisted of 55 patients with locally invasive pancreatic cancer (International Union Against Cancer [UICC] stage III in 36 patients and stage IV in 19) who had undergone resection. The patients were informed about the advantages and the adverse effects of postoperative chemotherapy, and prospectively selected either observation alone or postoperative chemotherapy. The postoperative chemotherapy regimen options were: (1) intraarterial chemotherapy alone, (2) systemic chemotherapy alone, or (3) intraarterial chemotherapy combined with systemic chemotherapy.ResultsOverall 1-year and 2-year survival rates after resection were 40.5% and 13.5%, respectively. Median survival time was 10.9 months. Twenty-nine patients (52.7%) received postoperative chemotherapy. On univariate analysis, only postoperative chemotherapy was associated with long-term survival (P < 0.01). In the patients with postoperative chemotherapy, the 1-year survival rate and MST were 61.7% and 16.3 months, compared with 20.1% and 7.9 months in the patients without postoperative chemotherapy. Multivariate analysis also showed that only postoperative chemotherapy was identified as an independent survival factor.ConclusionsIt was suggested that postoperative chemotherapy was essential for the improvement of survival in patients with locally invasive pancreatic cancer. 相似文献

Objectives: Irreversible electroporation (IRE) is a novel non-thermal ablative technique applied in the treatment of unresectable locally advanced pancreatic cancer (LAPC). This paper reports on the initial experience with IRE of unresectable LAPC in our institution. Methods: From October 2013 to March 2018, patients with unresectable LAPC referred for IRE at the Department of Gastrointestinal Surgery, Aalborg University Hospital, were considered for inclusion in the study. Ninety-day morbidity, 30-day mortality, pain score, length of hospital stay (LOS) and overall survival (OS) were recorded. Results: We included 33 patients receiving 40 IRE ablations in total. The median visual analogue scale (VAS)-score was four (range 0–10) two hours after IRE, and one (range 0–8) eight hours after IRE. The median LOS was one day (range 1–13 days). Post-procedural complications occurred in 21 of 40 ablations (53%), of which eight (20%) were major (Clavien–Dindo grade III or more). A proportion of the observed complications might be attributed to disease progression and not IRE per se. Although not statistically significant, we observed increased severity of complications in tumors above 3.5?cm. The 30-day mortality was 5% (2/40). The median OS was 10.7 months (range 0.6–53.8 months) from the initial IRE procedure, and 18.5 months (range 4.9–65.8 months) from time of diagnosis. Conclusions: In our institution, IRE seems as a feasible consolidative treatment of unresectable LAPC with an acceptable safety profile. The oncological outcome of IRE in patients with unresectable LAPC is to be further evaluated in a planned phase 2 clinical trial (CHEMOFIRE-2). 相似文献

Background The goal of this study was to evaluate the association between patient quality of life (QoL) and survival in pancreatic cancer
patients undergoing care in a community hospital comprehensive cancer center.
Patients and Methods A consecutive case series of 55 histologically confirmed pancreatic cancer treated at Cancer Treatment Centers of America?
at Midwestern Regional Medical Center was studied between 04/01 and 11/04. The EORTC QLQ-C30 was utilized to assess patient
QoL. Kaplan–Meier method was used to calculate survival. Log-rank test was used to study the equality of survival distributions.
Multivariate Cox regression analyses were then performed to evaluate the joint prognostic significance of those QoL and clinical
factors that were shown to be prognostic upon univariate analyses.
Results Of the 55 patients, 28 were newly diagnosed and 27 had prior treatment history. The median age was 55 years (range 33–74 years).
Majority (34) had stage IV disease at diagnosis. The QLQ-C30 parameters to show statistically significant associations with
survival were physical, role, and emotional functioning scales and fatigue, appetite loss, constipation, and diarrhea symptom
scales.
Conclusions We found that patient QoL, as measured by the QLQ-C30 physical functioning scale, provides useful prognostic information,
independent of multiple cancer symptoms, in patients with pancreatic cancer. While these findings require further investigation
in large patient cohorts, they may have important implications for patient stratification in clinical trials, as well as aid
in clinical decision making. 相似文献

BackgroundThe treatment options for patients with locally advanced pancreatic cancer (LAPC) have improved in recent years and consequently survival has increased. It is unknown, however, if elderly patients benefit from these improvements in therapy. With the ongoing aging of the patient population and an increasing incidence of pancreatic cancer, this patient group becomes more relevant. This study aims to clarify the association between increasing age, treatment and overall survival in patients with LAPC. MethodsPost-hoc analysis of a multicenter registry including consecutive patients with LAPC, who were registered in 14 centers of the Dutch Pancreatic Cancer Group (April 2015–December 2017). Patients were divided in three groups according to age (<65, 65–74 and ≥75 years). Primary outcome was overall survival stratified by primary treatment strategy. Multivariable regression analyses were performed to adjust for possible confounders. ResultsOverall, 422 patients with LAPC were included; 162 patients (38%) aged <65 years, 182 patients (43%) aged 65–74 and 78 patients (19%) aged ≥75 years. Chemotherapy was administered in 86%, 81% and 50% of the patients in the different age groups (p<0.01). Median overall survival was 12, 11 and 7 months for the different age groups (p<0.01).Patients treated with chemotherapy showed comparable median overall survival of 13, 14 and 10 months for the different age groups (p=0.11). When adjusted for confounders, age was not associated with overall survival. ConclusionElderly patients are less likely to be treated with chemotherapy, but when treated with chemotherapy, their survival is comparable to younger patients. 相似文献

A 68-year-old female visited a local clinic with epigastralgia. A routine laboratory test revealed jaundice and liver dysfunction. She was referred to this hospital. Abdominal computed tomography (CT) and endoscopic retrograde cholangio-pancreatography (ERCP) revealed that the density of the entire pancreas had decreased, and showed dilatation of the common bile duct (CBD) and the main pancreatic duct (MPD). Pancreatic cancer was diagnosed by cytological examination analyzing the pancreatic juice obtained by ERCP. When jaundice had decreased the tumor was observed via laparotomy. No ascites, liver metastasis, or peritoneal dissemination was observed. The entire pancreas was a hard mass, and a needle biopsy was obtained from the head, body and tail of the pancreas. These biopsies diagnosed a poorly differentiated adenocarcinoma. Hepaticojejunostomy was thus performed, and postoperative progress was good. Chemotherapy with 1000 mg/body per week of gemcitabine was administered beginning 15 d postoperatively. However, the patient suffered relatively severe side effects, and it was necessary to change the dosing schedule of gemcitabine. Abdominal CT revealed a complete response (CR) after 3 treatments. Therefore, weekly chemotherapy was stopped and was changed to monthly administration. To date, for 4 years after chemotherapy, the tumor has not reappeared. 相似文献
