Abstract
BACKGROUND Due to delayed diagnosis and a lower surgical indication rate, left-sided pancreatic ductal adenocarcinoma (PDAC) is often associated with a poor prognosis in comparison to pancreatic head tumors. Multi-visceral resections (MVR) associated with distal pancreatectomy could be proposed for patients presenting with locally infiltrating disease. METHODS We retrospectively analyzed a multi-centric cohort of left-sided PDAC patients operated on from 2009 to 2020. Thirteen European high-volume HPB centers participated in this study. We analyzed patients who underwent distal pancreatectomy (DP) associated with MVR and compared them to standard DP patients. RESULTS Among 258 patients treated curatively for PDAC of the body and tail, 28 patients successfully underwent MVR. A longer operative time was observed in the MVR group (295 min +/- 74 vs. 250 min +/- 96, p= 0.248). The post-operative complication rate was comparable between the two groups (46.4% in the MVR group vs. 62.2% in the control group, p= 0.108). The incidence of positive margin (R1) was similar between the two groups (28.6% vs. 26.6%; p=0.827). After a median follow-up of 25 (9-111) months, overall survival was comparable between the two groups (p= 0.519). CONCLUSIONS Multi-visceral resection in left-sided pancreatic ductal adenocarcinoma is safe and feasible and should be considered in selected cases as it seems to provide acceptable surgical and oncological outcomes.

Abstract
BACKGROUND The indications and benefits derived from staging laparoscopy (SL) for pancreatic cancer (PC) remain controversial. METHODS This study involved PC patients in whom resection had been considered possible between 2009 and 2020. We classified the patients into before 2014 (training set) and 2014 and later (validation set) groups, as SL was introduced in 2014, in our institution. In the training set, the predictors of non-curative factors were investigated, and reproducibility was confirmed in the validation set. In addition, the outcomes were compared between the datasets. RESULTS A total of 802 patients were classified into the training set (n = 241) and validation set (n = 561). In the training set, pancreatic body or tail tumors (odds ratio [OR]: 2.62: P = 0.039), CA19-9 > 88 U/ml (OR: 3.21: P = 0.018) and a tumor diameter >36 mm (OR: 6.07; P < 0.001) were independent predictors of non-curative factors. The increased rate of non-curative factors was confirmed as the number of predictors increased in the validation set. The curative resection (CR) rate was significantly higher in the validation set than in the training set (P = 0.035). Although there was no significant difference in the OS in the not-resected group (P = 0.895), the OS in the CR and non-CR group was significantly better in the validation set than in the training set (CR, P < 0.001; non-CR, P < 0.001). CONCLUSION The findings suggest potential candidates for SL and revealed improved outcomes by the advent of treatment strategies including SL.

Abstract
Pancreatic ductal adenocarcinoma (PDAC), a highly aggressive malignancy with a poor prognosis is usually detected at the advanced stage of the disease. The only US Food and Drug Administration-approved biomarker that is available for PDAC, CA 19-9, is most useful in monitoring treatment response among PDAC patients rather than for early detection. Moreover, when CA 19-9 is solely used for diagnostic purposes, it has only a recorded sensitivity of 79% and specificity of 82% in symptomatic individuals. Therefore, there is an urgent need to identify reliable biomarkers for diagnosis (specifically for the early diagnosis), ascertain prognosis as well as to monitor treatment response and tumour recurrence of PDAC. In recent years, proteomic technologies are growing exponentially at an accelerated rate for a wide range of applications in cancer research. In this review, we discussed the current status of biomarker research for PDAC using various proteomic technologies. This review will explore the potential perspective for understanding and identifying the unique alterations in protein expressions that could prove beneficial in discovering new robust biomarkers to detect PDAC at an early stage, ascertain prognosis of patients with the disease in addition to monitoring treatment response and tumour recurrence of patients.

A simple risk score for detecting radiological occult metastasis in patients with resectable or borderline resectable pancreatic ductal adenocarcinoma. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2021; 29:262-270. [PMID: 34314568 DOI: 10.1002/jhbp.1026] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 06/27/2021] [Accepted: 07/16/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND We advocated carbohydrate antigen (CA) 19-9 ≥ 150 U/mL and tumor size ≥30 mm as "high-risk markers" for predicting unresectability among patients with radiologically resectable (R) or borderline resectable (BR) pancreatic ductal adenocarcinoma (PDAC). The main aim is to establish a risk scoring system for occult abdominal metastasis (OAM) in R/BR PDAC. METHODS Predictors of OAM were investigated retrospectively in an experiment cohort from 2006 to 2018. The proposed risk scoring system was validated in another cohort from 2019 to 2020. RESULTS Five hundred and thirteen eligible patients were divided into the experimental (405 patients; OAM, 22%) and validation cohorts (108 patients). Multivariate analysis identified tumor location of body/tail (odds ratio [OR] 4.45, P < .0001) and "high-risk markers" (OR 2.07, P = .011) as independent predictors of OAM. A scoring system consisting of body/tail (yes: 1, no: 0) and "high-risk markers" (yes: 1, no: 0) was constructed. In the validation cohort, when staging laparoscopy (SL) was performed for patients with scores 1/2, the eligibility for SL, sensitivity, and negative predictive value of OAM were 55%, 91%, and 96%, respectively. CONCLUSIONS Tumor location of body/tail and "high-risk markers" were independent predictors of OAM, composing our simple and reproducible risk scoring system.

Abstract
Pancreatic cancer is one of the dismal malignant disease in gastrointestinal tract. However, since the recent literature reporting median survival of FOLFIRINOX (leucovorin clcium, fluorouracil, irinotecan hydrochloride, oxaliplatin) chemotherapy was more than 12 months in metastatic pancreatic cancer was published, the positive attitude toward the treatment of the advanced pancreatic cancer is gradually expanded among the medical and surgical oncologists. Due to multiple combination of potent chemotherapeutic agents, potential adverse side effects should be concerned when considering FOLFIRINOX. Herein, we report a 55-year old male patient with locally advanced pancreatic cancer who successfully underwent curative resection following by laparoscopic division of pancreaticosplenic ligament due to long-term preoperative use of FOLFIRINOX related hepatic toxicity associated with secondary hypersplenism. The present case suggests the extended radical PD with combined major vascular resection following laparoscopic division of pancreaticosplenic ligament containing splenic artery and vein can improve the safety of curative resection and may expand the potential indication of pancreatic cancer in well-selected long-term use of preoperative FOLFIRINOX induced hepatic toxicity associated with secondary hypersplenism.

Abstract
The accuracy of modern imaging techniques for the diagnosis of peritoneal carcinomatosis is poor. A breast cancer patient with a high serum CA15-3 level did not receive a definitive diagnosis of peritoneal dissemination by imaging examination and then underwent laparoscopy. Pathological examination showed peritoneal dissemination of breast cancer, but the biological markers were different from the primary lesion: ER(−), PgR(−), and Her2:3 +. T-DM1 therapy was very effective, and her systemic symptoms disappeared. Since biomarkers of metastatic lesions may sometimes change, laparoscopic biopsy is very important and useful.

Determining the CA19-9 concentration that best predicts the presence of CT-occult unresectable features in patients with pancreatic cancer: A population-based analysis. Pancreatology 2020; 20:1458-1464. [PMID: 32868184 DOI: 10.1016/j.pan.2020.07.405] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Revised: 07/07/2020] [Accepted: 07/28/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Serum CA19-9 concentration may be useful in triaging patients with pancreatic cancer for more intensive staging investigations. Our aim was to identify the CA19-9 cut-point with the greatest accuracy for detecting unresectable features not identified by CT scan, and to examine the performance of this and other cut-points in predicting the outcome of staging laparoscopy (SL). METHODS Patients with pancreatic cancer were drawn from two state-wide cancer registries between 2009 and 2011. We used classification and regression tree (CART) analysis to identify the CA19-9 cut-point which best predicted the presence of imaging-occult unresectable features, and compared its performance with that of a number of alternative cut-points. We then used logistic regression to test the association between CA19-9 concentration and detection of unresectable features in patients who underwent SL. RESULTS From the CART analysis, the optimal CA19-9 cut-point was 440 U/mL. CA19-9 ≥ 150 U/mL had a similar Youden Index, but greater sensitivity (69% versus 47%). This remained true for those who had obstructive jaundice at the time of CA19-9 sampling. CA19-9 concentration greater than or equal to 110 U/mL, 150 U/mL and 200 U/mL was associated with significantly greater odds of unresectable features being detected during SL. CONCLUSION Elevated serum CA19-9 concentration is a valid marker for CT-occult unresectable features; the most clinically appropriate cut-point appears to be ≥ 150 U/mL irrespective of the presence of jaundice. Clinical trials which evaluate the value of CA19-9 in the staging algorithm for pancreatic cancer are needed before it is routinely used in clinical practice.

Abstract
PURPOSE Staging laparoscopy is considered useful for determining treatment plans for advanced pancreatic cancer. However, the indications for staging laparoscopy are not clear. This study aimed to evaluate the safety of staging laparoscopy and its usefulness for detecting distant metastases in patients with pancreatic cancer. METHODS A total of 146 patients with pancreatic cancer who underwent staging laparoscopy between 2013 and 2019 were analyzed. Staging laparoscopy was performed in all pancreatic cancer patients in whom surgery was considered possible. RESULTS In this cohort, 42 patients (29%) were diagnosed with malignant cells on peritoneal lavage cytology, 9 (6%) had peritoneal dissemination, and 11 (8%) had liver metastases. A total of 48 (33%) had radiologically negative metastases. On a multivariate analysis, body and tail cancer [odds ratio (OR) 5.00, 95% confidence interval (CI) 2.15-11.6, p < 0.001], high CA19-9 level [OR 4.04, 95% CI 1.74-9.38, p = 0.001], and a resectability status of unresectable (OR 2.31, 95% CI 1.03-5.20, p = 0.04) were independent risk factors for radiologically negative metastases. CONCLUSIONS Staging laparoscopy can be safely performed and is useful for the diagnosis of radiologically negative metastases. Staging laparoscopy should be routinely performed for the accurate diagnosis of pancreatic cancer patients before pancreatectomy and/or local treatment, such as radiotherapy.

Abstract
Primary pancreatic lymphoma is a rare clinical entity representing <0.5% of pancreatic cancers and 1% of extranodal lymphomas. Due to the paucity of cases described in the literature, its clinicopathological features, differential diagnosis, optimal therapy and outcomes are not well defined. As the clinical manifestations are often non-specific, it can create a diagnostic pitfall for the unwary physician. Preoperative distinction of adenocarcinoma and primary pancreatic lymphoma is critical since the management and prognosis of these malignancies are mutually exclusive. Due to its rarity, epidemiological studies have been difficult to conduct. Chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin and vincristine) has proven to be effective. The authors present the case of a 52-year-old man with epigastric pain and obstructive jaundice. Further investigation with a CT of the abdomen and pelvis showed a low attenuation mass in the head of the pancreas measuring 35×25 mm, suspicious for malignancy. The mass involved the common bile duct distally causing moderate retrograde intrahepatic and extrahepatic biliary tree dilation of 14 mm. He underwent endoscopic retrograde cholangiopancreatography, sphincterotomy and insertion of a stent. Core biopsies confirmed the diagnosis of a high-grade B cell pancreas lymphoma. He started treatment with R-CHOP and prednisolone. Due to disease progression, he started treatment with DA-EPOCH-R (etoposide phosphate, prednisone, vincristine sulfate, cyclophosphamide, doxorubicin hydrochloride and rituximab). There was no clinical response, and treatment with RICE (rituximab, ifosfamide, carboplatin and etoposide) was initiated. He showed partial response and was under consideration for chimeric antigen receptor T cell therapy. He deteriorated clinically and succumbed to his disease 5 months following his initial presentation. This paper will provide an overview of the spectrum of haematological malignancies and describe useful features in distinguishing primary lymphoma of the pancreas from an adenocarcinoma, hence avoiding its surgical resection.

Abstract
Exocrine cancer of pancreas is the fourth leading cause of death in the USA among both men and women. Contrast enhanced multidetector-row computer tomography (MDCT) is the current modality of choice for the detection of distant metastasis in pancreatic cancer as a part of pre-operative workup, which helps decide on resectability. Authors present a first ever reported case of an incidental liver metastasis found on intra-operative wedge hepatic biopsy during Whipple’s procedure for pancreatic cancer. This pancreatic cancer was initially thought to be resectable based on MDCT staging per guidelines. The case highlights the importance of diagnostic staging laparoscopy and neoadjuvant chemotherapy before resecting pancreatic adenocarcinoma.

Abstract
BACKGROUND Patients with potentially resectable pancreatic ductal adenocarcinoma (PDAC) are frequently found to be unresectable on exploration due to small distant metastasis. This study was to investigate predictors of small distant metastasis in patients with potentially resectable PDAC. METHODS Patients who underwent surgical exploration for potentially resectable PDAC from 2013 to 2014 were reviewed retrospectively and divided into two groups according to whether distant metastases were encountered on exploration. Then, univariate and multivariate logistic regression analyses were used to identify predictors of distant metastasis. A scoring system to predict distant metastasis of PDAC on exploration was constructed based on the regression coefficient of a multivariate logistic regression model. RESULTS A total of 235 patients were included in this study. Mean age of the study population was 61.7 ± 10.4 years old. Upon exploration, distant metastases were found intraoperatively in 62 (26.4%) patients, while the remaining 173 were free of distant metastases. Multivariate logistic regression analysis identified that age ≤ 62 years old (p < 0.001), male sex (p = 0.011), tumor size ≥4.0 cm (p < 0.001), alanine aminotransferase level (ALT) < 125 U/L (p < 0.001), and carbohydrate antigen (CA19-9) level ≥ 385 U/mL (p < 0.001) were independent risk factors for occult distant metastasis of PDAC. A preoperative scoring system (0-8 points) for distant metastasis on exploration was constructed using these five factors. The receiver operating characteristic curves showed that the area under the curve of this score was 0.85. A score of 6 points was suggested to be the optimal cut-off value, and the sensitivity and specificity were 85% and 69%, respectively. CONCLUSIONS Distant metastasis is still frequently encountered on exploration for patients with potentially resectable PDAC. Younger age, male sex, larger tumor size, low ALT level and high CA19-9 level are independent predictors of unexpected distant metastasis on exploration.

Staging laparoscopy with ultrasound and near-infrared fluorescence imaging to detect occult metastases of pancreatic and periampullary cancer. PLoS One 2018; 13:e0205960. [PMID: 30383818 PMCID: PMC6211678 DOI: 10.1371/journal.pone.0205960] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Accepted: 10/04/2018] [Indexed: 02/08/2023] Open
Abstract
Introduction Up to 38% of pancreatic and periampullary cancer patients undergoing curative intended surgery turn out to have incurable disease. Therefore, staging laparoscopy (SL) prior to laparotomy is advised to spare patients the morbidity, inconvenience and expense of futile major surgery. The aim of this study was to assess the added value of SL with laparoscopic ultrasonography (LUS) and laparoscopic near-infrared fluorescence imaging (LFI). Methods All patients undergoing curative intended surgery of pancreatic or periampullary cancer were included prospectively in this single arm study. Patients received an intravenous infusion of 10 mg indocyanine green (ICG) one or two days prior to surgery to allow LFI. Suspect lesions were analyzed via biopsy or resection. Follow-up visits after surgery occurred every three months. Results A total of 25 patients were included. Suspect lesions were identified in 7 patients: liver metastases (n = 2; identified by inspection, LUS, and LFI), peritoneal metastases (n = 1; identified by inspection only), and benign lesions (n = 4; identified by inspection or LUS). Quality of LFI was good in 67% (10/15) of patients dosed one day and 89% (8/9) dosed two days prior to surgery. A futile laparotomy was averted in 3 patients (12%). Following SL the primary tumor was resected in 20 patients. Two patients (10%) developed metastases within 3 months after resection. Conclusions Despite current preoperative imaging modalities metastases are still identified during surgery. This study shows limited added value of LUS during SL in patients with pancreatic or periampullary cancer. LFI was of added value due to its high negative predictive value in case of suspect hepatic lesions identified by inspection.

Abstract
Background At the time of planned pancreatoduodenectomy patients frequently undergo exploratory laparotomy without resection, leading to delayed systemic therapy. This study aimed to develop and validate a prognostic model for the preoperative prediction of resectability of pancreatic head tumours. Methods This was a retrospective study of patients undergoing attempted resection for confirmed malignant tumours of the pancreatic head in a university hospital in Hannover, Germany. The prognostic value of patient and tumour characteristics was investigated in a multivariable logistic regression model. External validation was performed using data from two other centres. Results Some 109 patients were included in the development cohort, with 51 and 175 patients in the two validation cohorts. Eighty patients (73·4 per cent) in the development cohort underwent resection, and 37 (73 per cent) and 141 (80·6 per cent) in the validation cohorts. The main reasons for performing no resection in the development cohort were: local invasion of vasculature or arterial abutment (15 patients, 52 per cent), and liver (12, 41 per cent), peritoneal (8, 28 per cent) and aortocaval lymph node (6, 21 per cent) metastases. The final model contained the following variables: time to surgery (odds ratio (OR) 0·99, 95 per cent c.i. 0·98 to 0·99), carbohydrate antigen 19-9 concentration (OR 0·99, 0·99 to 0·99), jaundice (OR 4·45, 1·21 to 16·36) and back pain (OR 0·02, 0·00 to 0·22), with an area under the receiver operating characteristic (ROC) curve (AUROC) of 0·918 in the development cohort. AUROC values were 0·813 and 0·761 in the validation cohorts. The positive predictive value of the final model for prediction of resectability was 98·0 per cent in the development cohort, and 91·7 and 94·7 per cent in the two external validation cohorts. [Corrections added on 18 July 2018, after first online publication: The figures for OR of the variables time to surgery and CA19-9 in the abstract and in Table 3 and Table 4 were amended from 1·00 to 0·99]. Conclusion For preoperative prediction of the likelihood of resectability of pancreatic head tumours, this validated model is a valuable addition to CT findings.

Abstract
Sentinel lymph node procedures for gastric cancer resections using indocyanine green (ICG) linked to Nanocoll outperformed normal ICG but did not provide information on possible lymph node metastasis. Carcinoembryonic antigen targeted fluorescent imaging using SGM‐101 was successful in both pancreatic and colorectal cancer. A large phase III multicentre trial will soon be initiated in colorectal cancer patients.

Abstract
BACKGROUND Proper staging is critical to the management of pancreatic ductal carcinoma (PDAC). Laparoscopy has been used to stage patients without gross metastatic disease with variable success. OBJECTIVES We aimed to identify the frequency of patients diagnosed by laparoscopy with occult metastatic disease. Also, we looked for variables related to a higher chance of occult metastasis. METHODS Patients with PDAC submitted to staging laparoscopy either immediately before pancreatectomy or as a separate procedure between January 2010 and December 2016 were included. None presented gross metastatic disease at initial staging. We used logistic regression to search for variables associated with metastatic disease. RESULTS The study population consisted of 63 patients. Among all patients, nine (16.7%) had occult metastases at laparoscopy. Unresectable tumor (Odds ratio = 18.0, P = 0.03), increasing tumor size (Odds ratio = 1.36, P = 0.01), and abdominal pain (Odds ratio = 5.6, P = 0.04) significantly predicted the risk of occult metastases in univariate analysis. In multivariate analysis, only tumor size predicted the risk of occult metastases. CONCLUSION Laparoscopy remains a valuable tool in PDAC staging. Patients with either large or unresectable tumors, or presenting with abdominal pain present the highest risk for occult intra-abdominal metastases.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States, with an estimated 53,670 new cases diagnosed and an estimated 43,090 deaths in 2017. This high mortality rate is in part due to the small percentage of patients diagnosed with local disease, as well as the biologically aggressive nature of the disease. While only 10-20% of patients will present with surgically resectable disease, this is the only possible curative therapy. Five-year survival of resected pancreatic cancer ranges from 12 to 27%. The National Comprehensive Cancer Network (NCCN) guidelines recommend specific guidelines for imaging modalities used in the diagnosis and staging of pancreatic adenocarcinoma. Indeed, high-quality imaging is not only necessary to accurately stage the disease, but is critical for the determination of key clinical decision branch points such as the determination of surgical resectability. Identification of the lesion within the pancreas, the degree of extra-pancreatic extension, and potential involvement of surrounding vascular structures with the tumor are all findings necessary to classify patients as having resectable, borderline resectable, or with unresectable primary tumors. This article reviews imaging modalities used to evaluate the pancreatic cancer patient from the surgeon's perspective, with particular emphasis on determination of resectability and preoperative planning, as well as imaging in the postoperative period.

Abstract
LESSONS LEARNED There is no presenting parameter that predicts the success of neoadjuvant therapy for pancreatic cancer.Despite the images on scans following neoadjuvant therapy, all patients should be evaluated, because inflammation following radiation therapy (RT) may overstate the extent of tumor and vascular involvement. BACKGROUND In patients presenting with locally advanced pancreatic adenocarcinoma deemed unresectable by two pancreatic cancer surgeons, we analyzed presenting tumor size, extent of vascular involvement, tumor markers, response to neoadjuvant gemcitabine (G), docetaxel (T), and capecitabine (X) with or without additional chemoradiotherapy with GX on R0 resection rates (≥2 mm margins), and survival. METHODS All patients had baseline magnetic resonance imaging (MRI) and/or computed tomography (CT) scans and endoscopic ultrasound. A baseline positron emission tomography-computed tomography (PET-CT) was performed in 39 patients. The scans were reviewed by two radiologists.GTX (gemcitabine 750 mg/m2 and docetaxel 30 mg/m2 on days 4 and 11 with capecitabine 1,500 mg/m2 days 1-14) was administered on a 3-week schedule for 6 cycles to patients with both arterial and venous-only involvement. Patients in the arterial arm received GX/RT before surgery, and those in the venous arm received GX/RT after R1 resection. Standard-dose RT was delivered by intensity-modulated radiation therapy (IMRT) or conformal fields to 5040 cGy along with capecitabine for 5 days and gemcitabine on day 5 of weeks 1, 2, 4, and 5 of RT, starting with the first full week of RT.A cancer antigen test 19-9 (CA 19-9) was obtained at baseline and days 4 and 11 of each cycle. The rate of change in CA 19-9 was calculated using the formula: (Log10 CA 19-9 time 0) - (Log10 CA 19-9 at 9 weeks)/9 weeks. This was derived based on the observation that the fall in CA 19-9 following effective chemotherapy is a second-order function. RESULTS Of the 34 patients with arterial involvement and 11 with extensive venous involvement who met the eligibility criteria and began GTX, only 5 patients in the arterial arm did not undergo subsequent resection. The remaining 40 patients were included in this analysis of presenting parameters with respect to R0 resection, disease-free survival (DFS), and overall survival (OS). R0 resection was achieved in 28 of 40 patients (70%), and R1 resection in the remaining 12 (30%). The OS after R0 resection was a median 37 months (95% confidence interval [CI]: 29.3-44.7) compared with 29 months (95% CI: 28.5-41.5) for those with R1 resection.Excluding four postoperative deaths, median DFS for the 25 (71%) with R0 resection was 31 months (95% CI: 11.3-51.1), and the median DFS for R1 resection was only 14 months (95% CI: 11.1-17). Eleven of the twenty-eight (39%) patients achieving R0 resection have not relapsed (median = 45 months, range = 25-71 months). CONCLUSION R0 resection, the goal of neoadjuvant treatment, can be achieved in 70% of patients presenting with locally advanced pancreatic cancer. The median DFS was 31 months (95% CI: 11. 3-51.1). No relationship was found with tumor size, degree of vascular involvement, carcinoembryonic antigen test (CEA), CA 19-9, degree of tumor regression on scan, fall in CA 19-9, or SUV on PET scan and subsequent survival.

Abstract
BACKGROUND Recent advances in imaging and the increasing use of neoadjuvant therapy puts the contemporary utility of staging laparoscopy for patients with pancreatic adenocarcinoma (PDAC) into question. This study aimed to develop a prognostic score to optimize prevention of an unnecessary laparotomy and minimize the rate for unnecessary laparoscopy. METHODS Clinicopathologic data were evaluated for all patients undergoing surgical intervention for PDAC between 2001 and 2015, who were stratified into group 1 (2001-2008) and group 2 (2009-2014). RESULTS The study identified 1001 patients eligible for analysis, 331 (33%) of whom underwent a staging laparoscopy before exploration. An unnecessary laparotomy was prevented for 44.4% of the patients in period 1 and for 24% of the patients in period 2 (p < 0.001). Male gender [odds ratio (OR), 1.8; p < 0.05], preoperative resectability (borderline resectable OR 2.1; p < 0.019; locally advanced OR 7.6; p < 0.001), CA 19-9 levels higher than 394 U/L (OR 3.1; p < 0.001), no neoadjuvant chemotherapy (OR 2.7; p = 0.012), and pancreatic body or tail lesions (OR 1.8; p = 0.063) were predictive of occult metastatic disease. The developed scoring index demonstrated a c-statistic of 0.729. The observed-to-expected ratio for the index at every score level validated the index's model. A score cutoff at 4 was able to detect 76.1% of radiographically occult metastatic disease. CONCLUSION The rate for unnecessary laparotomy among patients with PDAC has decreased in contemporary times, but unnecessary laparotomy still occurs for 1 in 4 patients. Using our scoring system, a cutoff of 4 allows 76% of radiographically occult metastases to be predicted, thereby selecting high-risk patients for laparoscopic biopsy and potentially avoiding a non-therapeutic laparotomy.

Abstract
OBJECTIVES We aimed to identify risk factors for latent distant organ metastasis in patients with radiographically defined locally advanced (RDLA) pancreatic ductal adenocarcinoma (PDAC). METHODS RDLA disease was defined as unresectable disease without distant organ metastasis based on resectability status by NCCN guidelines. Between January 2005 and November 2015, 110 consecutive patients underwent staging laparoscopy to rule out latent distant metastasis. Univariate and multivariate analyses were performed to identify risk factors for latent distant organ metastasis or peritoneal metastasis (PM), defined as peritoneal dissemination and/or positive peritoneal lavage cytology (PPC). RESULTS Latent distant organ metastasis was diagnosed by staging laparoscopy in 62 patients. PPC was found in 23%, peritoneal dissemination in 19%, and liver metastasis in 15%. Univariate analysis showed tumor location, preoperative CA 19-9 level and tumor size, and multivariate analysis revealed tumor size >55 mm and CA 19-9 level >60 IU/ml as risk factors for latent distant metastasis. Multivariate analysis showed pancreas body-tail tumors and tumor size >42 mm as risk factors for PM; 65.4% of pancreas body-tail tumors >42 mm had PM. CONCLUSIONS Patients with large pancreas body-tail tumors and high CA 19-9 level are at greater risk for latent distant organ metastasis or PM, and should undergo staging laparoscopy routinely for accurate diagnosis (UMIN000023125).

Abstract
Background The aim of current study is to verify usefulness of staging laparoscopy (stag-lap) for patient’s selection and to find prognostic factors in patients with radiographically defined locally advanced (RD-LA) pancreatic ductal adenocarcinoma (PDAC). Methods The LA disease was defined as an unresectable disease without distant organ metastasis based on resectability status of NCCN guideline in this study. Stag-lap was performed in 67 patients with RD-LA (2007–2012) which were divided into 4 groups according to metastatic site: group CY (peritoneal fluid or washing cytology positive and without any distant organ metastasis); group P (peritoneal dissemination); group L (liver metastasis); group LA (peritoneal fluid or washing cytology negative and without any distant organ metastasis). Clinical backgrounds, survival curves, and prognostic factors were investigated. Results There were 16 patients in CY group (24 %), 13 patients in P group (19 %), 10 patients in L group (15 %), and 28 patients in LA group (42 %). Median survival time was 13 months in CY group and 11 months in LA group, which was significantly better than 7 months in P group, respectively (p < 0.05). The rate of emergence of ascites in LA was significantly better than in CY or P groups (p < 0.05). Multivariate analysis showed that the presence of partial response and administration of second-line chemotherapy were significantly independent prognostic factors. Conclusions The majority of PDAC patients with RD-LA had occult distant organ metastasis. Clinical features and survival curves were different depending on the site of occult distant organ metastasis. Administration of second-line chemotherapy and responsiveness to chemotherapy were associated with favorable prognosis. Staging laparoscopy should be routinely performed in patients with RD-LA PDAC (UMIN000019936).

Abstract
BACKGROUND To identify indications for staging laparoscopy (SL) in patients with resectable pancreatic cancer, and suggest a pre-operative algorithm for staging these patients. METHODS Relevant articles were reviewed from the published literature using the Medline database. The search was performed using the keywords 'pancreatic cancer', 'resectability', 'staging', 'laparoscopy', and 'Whipple's procedure'. RESULTS Twenty four studies were identified which fulfilled the inclusion criteria. Of the published data, the most reliable surrogate markers for selecting patients for SL to predict unresectability in patients with CT defined resectable pancreatic cancer were CA 19.9 and tumour size. Although there are studies suggesting a role for tumour location, CEA levels, and clinical findings such as weight loss and jaundice, there is currently not enough evidence for these variables to predict resectability. Based on the current data, patients with a CT suggestive of resectable disease and (1) CA 19.9 ≥150 U/mL; or (2) tumour size >3 cm should be considered for SL. CONCLUSION The role of laparoscopy in the staging of pancreatic cancer patients remains controversial. Potential predictors of unresectability to select patients for SL include CA 19.9 levels and tumour size.

Abstract
Surgery is the cornerstone of oncologic therapy with curative intent. However, identification of tumor cells in the resection margins is difficult, resulting in nonradical resections, increased cancer recurrence and subsequent decreased patient survival. Novel imaging techniques that aid in demarcating tumor margins during surgery are needed. Overexpression of carcinoembryonic antigen (CEA) is found in the majority of gastrointestinal carcinomas, including colorectal and pancreas. We developed ssSM3E/800CW, a novel CEA-targeted near-infrared fluorescent (NIRF) tracer, based on a disulfide-stabilized single-chain antibody fragment (ssScFv), to visualize colorectal and pancreatic tumors in a clinically translatable setting. The applicability of the tracer was tested for cell and tissue binding characteristics and dosing using immunohistochemistry, flow cytometry, cell-based plate assays and orthotopic colorectal (HT-29, well differentiated) and pancreatic (BXPC-3, poorly differentiated) xenogeneic human-mouse models. NIRF signals were visualized using the clinically compatible FLARE™ imaging system. Calculated clinically relevant doses of ssSM3E/800CW selectively accumulated in colorectal and pancreatic tumors/cells, with highest tumor-to-background ratios of 5.1 ± 0.6 at 72 hr postinjection, which proved suitable for intraoperative detection and delineation of tumor boarders and small (residual) tumor nodules in mice, between 8 and 96 hr postinjection. Ex vivo fluorescence imaging and pathologic examination confirmed tumor specificity and the distribution of the tracer. Our results indicate that ssSM3E/800CW shows promise as a diagnostic tool to recognize colorectal and pancreatic cancers for fluorescent-guided surgery applications. If successfully translated clinically, this tracer could help improve the completeness of surgery and thus survival.

Abstract
OBJECTIVES Malignant ascites (MA) caused by peritoneal carcinomatosis is not uncommon in patients with pancreatic cancer. However, the clinical features and outcomes in these patients remain to be elucidated. METHODS Baseline characteristics and overall survival (OS) of consecutive patients with advanced pancreatic cancer who presented with MA were retrospectively evaluated. RESULTS Of 494 patients with advanced pancreatic cancer, 73 (15%) presented with MA. Patients with synchronous MA (n = 21), compared with those with metachronous MA (n = 52), had better performance status (P = 0.02), smaller amount of ascites (P < 0.01), and higher chance of receiving chemotherapy (57% vs 17%, P < 0.01), and resulted in longer OS (115 vs 42 days, P < 0.01). Overall survival was significantly longer in patients receiving chemotherapy than in those with best supportive care alone (124 vs 50 days, P < 0.01). In a multivariate analysis, chemotherapy was prognostic in addition to performance status, CRP, and small amount of MA; the hazard ratio of chemotherapy was 0.46, compared with best supportive care alone (P = 0.02). CONCLUSIONS Although the prognosis of pancreatic cancer patients with MA remains poor, selected patients may be candidate for chemotherapy, regardless of the timing of appearance of MA.

Current and future intraoperative imaging strategies to increase radical resection rates in pancreatic cancer surgery. BIOMED RESEARCH INTERNATIONAL 2014; 2014:890230.

Abstract
Prognosis of patients with pancreatic cancer is poor. Even the small minority that undergoes resection with curative intent has low 5-year survival rates. This may partly be explained by the high number of irradical resections, which results in local recurrence and impaired overall survival. Currently, ultrasonography is used during surgery for resectability assessment and frozen-section analysis is used for assessment of resection margins in order to decrease the number of irradical resections. The introduction of minimal invasive techniques in pancreatic surgery has deprived surgeons from direct tactile information. To improve intraoperative assessment of pancreatic tumor extension, enhanced or novel intraoperative imaging technologies accurately visualizing and delineating cancer cells are necessary. Emerging modalities are intraoperative near-infrared fluorescence imaging and freehand nuclear imaging using tumor-specific targeted contrast agents. In this review, we performed a meta-analysis of the literature on laparoscopic ultrasonography and we summarized and discussed current and future intraoperative imaging modalities and their potential for improved tumor demarcation during pancreatic surgery.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of cancer-related deaths in the Western world. Due to lack of specific symptoms and no accessible precursor lesions, primary diagnosis is commonly delayed, resulting in the identification of only 15-20% of patients with potentially curable disease. The major limiting factor is an already locally advanced or metastatic disease at the time of diagnosis. Consequently, systemic therapy forms the backbone of treatment strategy for the majority of patients. SUMMARY A deeper understanding of the molecular characteristics of pancreatic cancer has led to the identification of several potential therapeutic targets. A variety of targeted therapies are currently under clinical evaluation as single agents or in combination with chemotherapy for PDAC. This review highlights the current state of chemotherapy in pancreatic cancer and provides an outlook on its future perspectives. KEY MESSAGE This review focuses on the current chemotherapy regimens for the systemic treatment of PDAC. PRACTICAL IMPLICATIONS Various neoadjuvant approaches have been explored, including chemoradiation, chemotherapy followed by chemoradiation or intensified chemotherapy without defining a standard of care so far. The standard of care is gemcitabine or 5-fluorouracil. The oral fluoropyrimidine S-1 may be a promising new agent in this setting. For first-line treatment of metastatic pancreatic cancer, no targeted therapy has yet demonstrated clinical benefit apart from the combination of the tyrosine kinase inhibitor erlotinib plus gemcitabine. Recently, novel chemotherapeutic regimens such as FOLFIRINOX and gemcitabine plus nanoparticle albumin-bound paclitaxel have been introduced. Both combinations have proved to be superior to the standard gemcitabine regimen. For second-line treatment the combination of 5-fluorouracil/leucovorin and oxaliplatin yields improved results compared to best supportive care.

Abstract
BACKGROUND We have developed a method of distinguishing normal tissue from pancreatic cancer in vivo using fluorophore-conjugated antibody to carcinoembryonic antigen (CEA). The objective of this study was to evaluate whether fluorescence-guided surgery (FGS) with a fluorophore-conjugated antibody to CEA, to highlight the tumor, can improve surgical resection and increase disease-free survival (DFS) and overall survival (OS) in orthotopic mouse models of human pancreatic cancer. METHODS We established nude-mouse models of human pancreatic cancer with surgical orthotopic implantation of the human BxPC-3 pancreatic cancer. Orthotopic tumors were allowed to develop for 2 weeks. Mice then underwent bright-light surgery (BLS) or FGS 24 h after intravenous injection of anti-CEA-Alexa Fluor 488. Completeness of resection was assessed from postoperative imaging. Mice were followed postoperatively until premorbid to determine DFS and OS. RESULTS Complete resection was achieved in 92 % of mice in the FGS group compared to 45.5 % in the BLS group (p = 0.001). FGS resulted in a smaller postoperative tumor burden (p = 0.01). Cure rates with FGS compared to BLS improved from 4.5 to 40 %, respectively (p = 0.01), and 1-year postoperative survival rates increased from 0 % with BLS to 28 % with FGS (p = 0.01). Median DFS increased from 5 weeks with BLS to 11 weeks with FGS (p = 0.0003). Median OS increased from 13.5 weeks with BLS to 22 weeks with FGS (p = 0.001). CONCLUSIONS FGS resulted in greater cure rates and longer DFS and OS using a fluorophore-conjugated anti-CEA antibody. FGS has potential to improve the surgical treatment of pancreatic cancer.

Abstract
PURPOSE Tumor markers are substances found in blood and other biological fluids if tumor is present in the body. They can be produced by tumor itself or can be results of cancer - body relation. They may be used in the follow-up of cancer patients to identify tumor recurrence. Pre-treatment levels have prognostic tool and could signalize persistence of minimal residual disease despite radical surgery. METHODS We operated on 52 patients with upper GI malignancy (32 with gastric cancer and 20 with pancreatic cancer). Blood samples were taken before surgery and peritoneal samples immediately after laparotomy before any manipulation with tumor. All samples were examined by standard biochemical technique and the level was compared with a stage of the disease. RESULTS Patients suffering from gastric carcinoma of stage I and II had higher level of both markers in sera then in the peritoneal cavity, however most of them were within physiological range. Patients in stage III and IV had average marker levels in the peritoneal cavity higher than in sera. Number of positive findings was increasing according to the stage of the disease. The peritoneal levels of both markers varied extremely in higher stages. In patients suffering from pancreatic carcinoma the CEA levels both in sera and peritoneal cavity were parallel but peritoneal levels were slightly higher in stages III and IV. Ca 19 - 9 was more sensitive for pancreatic cancer. The percentage of positive findings was higher in sera but the level of Ca 19 - 9 was higher in the peritoneal cavity. The number of positive findings again correlated with the stage of the disease. CONCLUSIONS Levels of tumor markers in sera could signalize inoperability of tumor (Ca 19 - 9 in cases of pancreatic carcinoma); peritoneal levels could predict R1 resection especially in gastric cancer patients and risk of early peritoneal recurrence of the disease. Difference between the levels in the peritoneum and sera may signalize the route of dissemination (hematogenous and intraperitoneal).

Abstract
BACKGROUND Staging laparoscopy (SL) is not regularly performed for patients with hepatocellular carcinoma (HCC). It may change treatment strategy, preventing unnecessary open exploration. An additional advantage of SL is possible biopsy of the nontumorous liver to assess fibrosis/cirrhosis. This study aimed to determine whether SL for patients with HCC still is useful. METHODS Patients with HCC who underwent SL between January 1999 and December 2011 were analyzed. Their demographics, preoperative imaging studies, surgical findings, and histology were assessed. RESULTS The 56 patients (34 men and 22 women; mean age, 60 ± 14 years) in this study underwent SL for assessment of extensive disease or metastases. For two patients, SL was unsuccessful because of intraabdominal adhesions. For four patients (7.1 %), SL showed unresectability because of metastases (n = 1), tumor progression (n = 1), or severe cirrhosis in the contralateral lobe (n = 2). An additional five patients did not undergo laparotomy due to disease progression detected on imaging after SL. Exploratory laparotomy for the remaining 47 patients showed 6 (13 %) additional unresectable tumors due to advanced tumor (n = 5) or nodal metastases (n = 1). Consequently, the yield of SL was 7 % (95 % confidence interval (CI), 3-17 %), and the accuracy was 27 % (95 % CI, 11-52 %). A biopsy of the contralateral liver was performed for 45 patients who underwent SL, leading to changes in management for 4 patients (17 %) with cirrhosis. CONCLUSIONS The overall yield of SL for HCC was 7 %, and the accuracy was 27 %. When accurate imaging methods are available and additional percutaneous liver biopsy is implemented as a standard procedure in the preoperative workup of patients with HCC, the benefit of SL will become even less.

Abstract
BACKGROUND: Diagnostic laparoscopy helps in diagnosing and staging Gastrointestinal (GI) cancers. Routine laparoscopy before laparotomy, especially in cancers that have equivocal operability, helps to avoid unnecessary laparotomies. Present study evaluates utility of laparoscopy in diagnosing and staging GI cancers. MATERIALS AND METHODS: Diagnostic laparoscopy was done in 41 patients with gastrointestinal (GI) cancers who were thought to have equivocal operability. Patients with suspected or known non-metastatic GI cancers, in whom resectability was found doubtful by clinical assessment and pre-operative imaging, were included. Patients with non-GI cancers (lymphoma, gynaecologic cancers, genitourinary cancers, retroperitoneal sarcoma, sarcoma and abdominal metastasis of non-GI cancers) and metastatic cancers which were beyond the scope of curative surgery were excluded from the study. RESULTS: After diagnostic laparoscopy (DL) five patients had benign diagnosis. Out of 36 patients with malignant diagnosis, after DL, 22 patients (61.1%) were inoperable, 11 patients (30.6%) were operable, and three (8.3%) patients were of equivocal operability. Sensitivity, specificity, positive predictive value, and negative predictive value of laparoscopy in detecting operability were 100%, 91.7%, 81.8%, and 100%, respectively. CONCLUSIONS: Laparoscopy helped in a significant number of patients with advanced GI cancers to avoid laparotomy. The morbidity of DL was acceptable.

Prospective efficacy and safety study of neoadjuvant gemcitabine with capecitabine combination chemotherapy for borderline-resectable or unresectable locally advanced pancreatic adenocarcinoma. Surgery 2012; 152:851-62. [PMID: 22682078 DOI: 10.1016/j.surg.2012.03.010] [Citation(s) in RCA: 75] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2011] [Accepted: 03/08/2012] [Indexed: 12/14/2022]
Abstract
BACKGROUND To determine the safety and efficacy of neoadjuvant gemcitabine/capecitabine followed by surgery for the treatment of locally advanced pancreatic adenocarcinoma (LAPC). METHODS Patients with histologically confirmed LAPC were given 3-6 cycles of fixed-dose rate gemcitabine/capecitabine every 3 weeks. At the end of chemotherapy, patients were restaged and underwent surgery if the disease was not classified as unresectable. Our institutional criteria were used to classify respectability, which was recategorized on the basis of National Comprehensive Cancer Network (NCCN) criteria retroactively. The primary end point was rate of microscopic curative resection. RESULTS Forty-three eligible patients (18 with borderline resectable disease and 25 with unresectable disease on the basis of NCCN criteria) were enrolled. The radiologic response rate was 18.6%. Grade three or worse adverse events were mainly hand-foot syndrome (11%), and there were no grade four adverse events. Surgery was performed in 17 patients (39.5%); pathologic curative resection (R0) was achieved in 14 patients (32.5%) among total 43 patients, and 82.3% (14/17) among the 17 resected patients. With 43-month follow-up, the median overall was 16.6 months with a median progression-free survival of 10.0 months. Median overall survival was 23.1 months in patients who underwent surgery and 13.2 months in patients who could not complete the surgery (P = .017). CONCLUSION A subset of patients with borderline or unresectable pancreatic cancer could be performed curative tumor resection after neoadjuvant chemotherapy. Some patients might be benefit on survival from neoadjuvant chemotherapy after surgical resection.

Abstract
BACKGROUND The aim of this study was to improve fluorescence laparoscopy of pancreatic cancer in an orthotopic mouse model with the use of a light-emitting diode (LED) light source and optimal fluorophore combinations. STUDY DESIGN Human pancreatic cancer models were established with fluorescent FG-RFP, MiaPaca2-GFP, BxPC-3-RFP, and BxPC-3 cancer cells implanted in 6-week-old female athymic mice. Two weeks postimplantation, diagnostic laparoscopy was performed with a Stryker L9000 LED light source or a Stryker X8000 xenon light source 24 hours after tail-vein injection of CEA antibodies conjugated with Alexa 488 or Alexa 555. Cancer lesions were detected and localized under each light mode. Intravital images were also obtained with the OV-100 Olympus and Maestro CRI Small Animal Imaging Systems, serving as a positive control. Tumors were collected for histologic analysis. RESULTS Fluorescence laparoscopy with a 495-nm emission filter and an LED light source enabled real-time visualization of the fluorescence-labeled tumor deposits in the peritoneal cavity. The simultaneous use of different fluorophores (Alexa 488 and Alexa 555), conjugated to antibodies, brightened the fluorescence signal, enhancing detection of submillimeter lesions without compromising background illumination. Adjustments to the LED light source permitted simultaneous detection of tumor lesions of different fluorescent colors and surrounding structures with minimal autofluorescence. CONCLUSIONS Using an LED light source with adjustments to the red, blue, and green wavelengths, it is possible to simultaneously identify tumor metastases expressing fluorescent proteins of different wavelengths, which greatly enhanced the signal without compromising background illumination. Development of this fluorescence laparoscopy technology for clinical use can improve staging and resection of pancreatic cancer.

Extended distal pancreatectomy with en bloc resection of the celiac axis for locally advanced pancreatic cancer: a case report and review of the literature. Case Rep Med 2012; 2012:543167.

Abstract
Due to a lack of early symptoms, pancreatic cancers of the body and tail are discovered mostly at advanced stages. These locally advanced cancers often involve the celiac axis or the common hepatic artery and are therefore declared unresectable. The extended distal pancreatectomy with en bloc resection of the celiac artery may offer a chance of complete resection. We present the case of a 48-year-old female with pancreatic body cancer invading the celiac axis. The patient underwent laparoscopy to exclude hepatic and peritoneal metastasis. Subsequently, a selective embolization of the common hepatic artery was performed to enlarge arterial flow to the hepatobiliary system and the stomach via the pancreatoduodenal arcades from the superior mesenteric artery. Fifteen days after embolization, the extended distal pancreatectomy with splenectomy and en bloc resection of the celiac axis was carried out. The postoperative course was uneventful, and complete tumor resection was achieved. This case report and a review of the literature show the feasibility and safety of the extended distal pancreatectomy with en bloc resection of the celiac axis. A preoperative embolization of the celiac axis may avoid ischemia-related complications of the stomach or the liver.

Abstract
OBJECTIVES The role of laparoscopy in staging periampullary malignancies is to detect small-volume metastatic disease not visible on preoperative imaging. Owing to improvements in preoperative imaging, some centers no longer undertake routine laparoscopic staging, whereas others still find it a useful pre-exploration tool. METHODS This study investigated the diagnostic yield of staging laparoscopies in 137 consecutive potentially resectable patients with periampullary malignancies. Serology on presentation, tumor size on computed tomography and proinflammatory markers such as C-reactive protein, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and Glasgow Prognostic Score were also examined to see if they were able to identify patients more likely to benefit from staging laparoscopy. RESULTS Laparoscopy identified occult disease in 16.1% of the patients. Only tumor diameter on cross-sectional imaging was related to an increase in diagnostic yield on staging laparoscopy. Area-under-curve values for tumor size and occult disease at laparoscopy were 0.8, with P = 0.0001. CONCLUSION Staging laparoscopy is a useful adjunct to computed tomography in staging periampullary cancers. Tumor size (especially >45 mm) is the only preoperative marker predictive of unexpected occult disease and may be used to select high-risk patients for laparoscopic staging.

Abstract
PURPOSE As laparoscopy can detect imaging-occult metastatic lesions, it has been validated as a means of improving the assessment of tumor staging. Although controversy exists as to whether the procedure should be used routinely or selectively in pancreatic cancer patients, patients considered for treatment protocols for locally unresectable pancreatic cancer should be staged laparoscopically before initiation of therapy. We evaluate the feasibility and safety of advanced staging laparoscopy including peritoneal lavage cytology, laparoscopic ultrasound sonography (LUS), and LUS-guided biopsy through a single incision for locally advanced pancreatic cancer. METHODS Staging laparoscopy was performed in 44 patients with pancreatic cancer for deciding on treatment strategy. Our procedures included extensive peritoneal lavage of abdominal cavity for cytology, LUS for small metastasis detection, and tissue sample excision including LUS-guided biopsy. Eleven consecutive patients were treated with a single-incision staging laparoscopy approach (SI-SL group). The clinical parameters were compared between the SI-SL group and the multi-incision staging laparoscopy group (multi-incision group). RESULTS The mean operating time was longer and bleeding volume was less in the SI-SL group, although the differences were without statistical significance. The conversion rates to laparotomy were 9% in the SI-SL group and 30% in the multi-incision group. There were no severe postoperative complications. LUS-guided biopsy revealed malignancy for 3 patients in the SI-SL group. CONCLUSIONS Advanced SI-SL is a feasible and safe alternative to the multi-incision approach for pancreatic cancer.

Abstract
BACKGROUND Preoperative imaging is often inadequate in excluding unresectable pancreatic cancer. Accordingly, many groups employ staging laparoscopy (SL), although none have evaluated SL after preoperative magnetic resonance imaging (MRI). We performed a retrospective, indirect cost-effectiveness analysis of SL after MRI for pancreatic head lesions. METHODS All MRI scans administered for proximal pancreatic cancer between 2004 and 2008 were reviewed and the clinical course of each patient determined. We queried our billing database to render average total costs for all inpatients with proximal pancreatic cancer who underwent pancreaticoduodenectomy, palliative bypass or an endoscopic stenting procedure. We then performed an indirect evaluation of the cost of routine SL. RESULTS The average costs of hospitalization for patients undergoing pancreaticoduodenectomy, open palliative bypass and endoscopic palliation were: US$26, 122.43, US$21, 957.18 and US$11, 304.00, respectively. The calculated cost of SL without laparotomy was US$2966.25 or US$1538.61 prior to laparotomy. The calculated cost of treating unresectable disease by outpatient laparoscopy followed by endoscopy was US$5943.17. Routine SL would increase our costs by US$76, 967.46 (3.6%). CONCLUSIONS Staging laparoscopy becomes cost-effective by diverting unresectable patients from operative to endoscopic palliation. Given the paucity of missed metastases on MRI, the yield of SL is marginal and its cost-effectiveness is poor. Future studies should address the utility of SL by both examining this issue prospectively and investigating the cost-effectiveness of endoscopic vs. surgical palliation in a manner that takes account of survival and quality of life data.

Abstract
Natural orifice transluminal endoscopic surgery (NOTES) has gained a great deal of attention from gastroenterologists and surgeons all over the world since its introduction in 2000. The field of NOTES has advanced tremendously since that time and exciting and well-designed research has been reported. Both randomized controlled trials and results from large national and international registries have been published. Many experimental and clinical studies have discussed transesophageal, transgastric, transvaginal and transrectal access for a variety of NOTES procedures. Transvaginal access has been the most frequently reported NOTES access route in clinical trials. When suitable instruments become available, a true comparison of NOTES with current laparoscopic approaches can be realized.

Abstract
BACKGROUND Staging laparoscopy can visualize peritoneal and liver metastases in pancreatic cancer otherwise undetectable by preoperative imaging. However, false-negative rates may be as high as 18%-26%. The aim of the present study was to improve detection of metastatic pancreatic cancer with the use of fluorescence laparoscopy (FL) in a nude-mouse model with the tumors expressing green fluorescent protein (GFP). METHODS The carcinomatosis mouse model of human pancreatic cancer was established by intraperitoneal injections of green fluorescent protein-expressing MiaPaca-2 human pancreatic cancer cells into 6-week-old female athymic mice. Two weeks later, mice underwent diagnostic laparoscopy. Laparoscopy was performed first under standard brightfield lighting, followed by fluorescent lighting. The number of metastatic foci identified within the four quadrants of the peritoneal cavity was recorded. After laparoscopy, the animals were sacrificed, opened, and imaged with the OV-100 Small Animal Imaging system as a positive control to identify metastasis. Tumors were collected and processed for histologic review. RESULTS FL enabled visualization of pancreatic cancer metastatic foci not visualized with standard brightfield laparoscopy (BL). Under FL, in 1 representative mouse, 26 separate micrometastatic lesions were identified. In contrast, only very large tumors were seen using BL. Use of the OV-100 images, as positive controls, confirmed the presence of tumor foci. FL thus allowed identification and exact localization of submillimeter tumor foci. Such small-sized tumor foci were not distinguished from surrounding tissue under BL. All malignant lesions were histologically confirmed. CONCLUSIONS The use of FL enables the identification of tumor foci that cannot be seen with standard laparoscopy. The technology described in this report has important potential for the clinical development of FL.

Abstract
PURPOSE The use of chemoradiotherapy (CRT) for localized and unresectable pancreatic cancer has been disputed because of high probability of distant metastasis. Thus, we analyzed the effect of clinical parameters on tumor response, early distant metastasis within 3 months (DM(3m)), and overall survival to identify an indicator for selecting patients who would benefit from CRT. METHODS AND MATERIALS This study retrospectively analyzed the data from 84 patients with localized and unresectable pancreatic cancer who underwent CRT between August 2002 and October 2009. Sex, age, tumor size, histological differentiation, N classification, pre- and post-treatment carbohydrate antigen (CA) 19-9 level, and CA 19-9 percent decrease were analyzed to identify risk factors associated with tumor response, DM(3m), and overall survival. RESULTS For all 84 patients, the median survival time was 12.5 months (range, 2-31.9 months), objective response (complete response or partial response) to CRT was observed in 28 patients (33.3%), and DM(3m) occurred in 24 patients (28.6%). Multivariate analysis showed that pretreatment CA 19-9 level (≤400 vs. >400 U/ml) was significantly associated with tumor response (45.1% vs. 15.2%), DM(3m) (19.6% vs. 42.4%), and median overall survival time (15.1 vs. 9.7 months) (p < 0.05 for all three parameters). CONCLUSION For patients with localized and unresectable pancreatic cancer, pretreatment CA 19-9 level could be helpful in predicting tumor response, DM(3m), and overall survival and identifying patients who will benefit from CRT.

Abstract
OBJECTIVE The aims of this study were to verify whether the selective use of staging laparoscopy can prevent unnecessary laparotomy and to find a surrogate marker for surgical unresectability in patients with potentially or borderline resectable pancreatic cancer. METHODS Group A consisted of consecutive 33 patients evaluated between 2005 and 2006 and who directly underwent open laparotomy for planned surgical resection. Group B consisted of consecutive 61 patients evaluated between 2007 and 2009 and of whom 16 patients (26%) had a staging laparoscopy due to the presence of high-risk markers of unresectability defined as carbohydrate antigen 19-9 level 150 U/mL or greater and tumor size 30 mm or greater. RESULTS The frequency of unnecessary laparotomies for occult distant organ metastasis was significantly different between groups A and B (18% and 3%, respectively; P = 0.021). Of 16 patients who underwent staging laparoscopy in group B, 5 patients (31%) had occult metastases. The multivariate analysis showed that the presence of high-risk markers and extrapancreatic plexus invasion on multidetector-row computed tomography were significant independent risk factors for unresectability. CONCLUSIONS The presence of high-risk markers was associated with surgical unresectability in patients with potentially or borderline resectable pancreatic cancer. The selective use of staging laparoscopy decreased the frequency of unnecessary laparotomy by detecting minute metastases.

Abstract
Pancreatic cancer is a relatively common malignancy of the gastrointestinal tract for which complete surgical excision remains the only curative option. Being infiltrative in nature and bearing a complex anatomical relationship with various organs, peritoneal ligaments and vascular structures, accurate anatomical staging is key in treatment of these patients. In this article, we will discuss and provide a brief overview of anatomy and use of imaging in staging pancreatic cancer.

Abstract
Even after extensive preoperative assessment, staging laparoscopy may allow avoidance of non-therapeutic laparotomy in patients with radiographically occult metastatic or locally unresectable disease. Staging laparoscopy is associated with decreased postoperative pain, a shorter hospital stay and a higher likelihood of receiving systemic therapy compared to laparotomy but its yield has decreased with improvements in imaging techniques. Current uses of staging laparoscopy include the following: (1) In the staging of pancreatic adenocarcinoma, laparoscopic staging allows for the identification of sub-radiographic metastatic disease in locally advanced cancer in approximately 30% of patients and, in radiographically resectable cancer, may identify metastatic disease in 10%-15% of cases; (2) In colorectal liver metastases, selective use of laparoscopic staging in patients with a clinical risk score of over 2 identifies unresectable disease in approximately 20% of patients; (3) In hepatocellular carcinoma, laparoscopic staging could be selectively used in high-risk patients such as those with clinically apparent liver cirrhosis and in patients with major vascular invasion or bilobar tumors; and (4) In biliary tract malignancy, staging laparoscopy may be used in all patients with potentially resectable primary gallbladder cancer and in selected patients with T2/T3 hilar cholangiocarcinoma. Because of the decreasing yield of SL secondary to improvements in imaging techniques, staging laparoscopy should be used selectively for patients with pancreatic and hepatobiliary malignancy to avoid unnecessary non-therapeutic laparotomy and to improve resource utilization. Each individual surgeon should apply his or her threshold as to whether staging laparoscopy is indicated according to the quality of preoperative imaging studies and the availability of resources at their own institution.

Abstract
The prognosis for locally advanced pancreatic carcinoma remains dismal despite advances in chemotherapy and radiotherapy over the past few decades. The use of radiotherapy for pancreatic carcinoma is often disputed because of the hypothesis that patients with pancreatic cancer die from distant metastases. It is well accepted that the greatest chance for cure of pancreatic cancer involves surgical resection of the primary tumor. However, there is much controversy about the role of radiotherapy in local disease control. The aim of this Review is to discuss data from the available studies, both prospective and retrospective, that evaluate treatment options for locally advanced pancreatic cancer. We focus on the benefits associated with local therapies, including radiotherapy and surgical resection, as they relate to improved local disease control, prolonged overall survival and improved symptom control.

Abstract
BACKGROUND The use of fluorescent proteins to label tumors is revolutionizing cancer research, enabling imaging of both primary and metastatic lesions, which is important for diagnosis, staging, and therapy. This report describes the use of fluorescence laparoscopy to image green fluorescent protein (GFP)-expressing tumors in an orthotopic mouse model of human pancreatic cancer. METHODS The orthotopic mouse model of human pancreatic cancer was established by injecting GFP-expressing MiaPaCa-2 human pancreatic cancer cells into the pancreas of 6-week-old female athymic mice. On postoperative day 14, diagnostic laparoscopy using both white and fluorescent light was performed. A standard laparoscopic system was modified by placing a 480-nm short-pass excitation filter between the light cable and the laparoscope in addition to using a 2-mm-thick emission filter. A camera was used that allowed variable exposure time and gain setting. For mouse laparoscopy, a 3-mm 0° laparoscope was used. The mouse's abdomen was gently insufflated to 2 mm Hg via a 22-gauge angiocatheter. After laparoscopy, the animals were sacrificed, and the tumors were collected and processed for histologic review. The experiments were performed in triplicate. RESULTS Fluorescence laparoscopy enabled rapid imaging of the brightly fluorescent tumor in the pancreatic body. Use of the proper filters enabled simultaneous visualization of the tumor and the surrounding structures with minimal autofluorescence. Fluorescence laparoscopy thus allowed exact localization of the tumor, eliminating the need to switch back and forth between white and fluorescence lighting, under which the background usually is so darkened that it is difficult to maintain spatial orientation. CONCLUSION The use of fluorescence laparoscopy permits the facile, real-time imaging and localization of tumors labeled with fluorescent proteins. The results described in this report should have important clinical potential.

Abstract
PURPOSE To prospectively evaluate the utility of dynamic contrast material-enhanced magnetic resonance (MR) imaging in predicting the response of locally advanced pancreatic cancer to combined chemotherapy and antiangiogenic therapy. MATERIALS AND METHODS This prospective, institutional review board-approved, HIPAA-compliant study with informed consent assessed dynamic contrast-enhanced MR imaging in 11 patients (mean age, 54.3 years; six men and five women) with locally invasive pancreatic cancer before and 28 days after combined chemotherapy and antiangiogenic therapy. Axial perfusion images were obtained after injection of 0.1 mmol gadopentetate dimeglumine per kilogram of body weight. Sagittal images of the upper abdominal aorta were obtained for arterial input function calculation. A two-compartment kinetic model was used to calculate the perfusion parameters K(trans) (the rate constant that represents transfer of contrast agent from the arterial blood into the extravascular extracellular space), K(ep) (the rate constant that represents transfer of contrast agent from the extravascular extracellular space to the blood plasma), and volume of distribution (v(e)). Semiquantitative measurements, peak tissue gadolinium concentration (C(peak)), maximum slope of gadolinium increase (slope), and area under the gadolinium curve at 60 seconds (AUC(60)) were also calculated. Perfusion parameters and tumor size changes were correlated with carbohydrate antigen 19-9 levels. Comparisons between pre- and posttreatment studies were performed by using the Wilcoxon signed rank test, and comparisons between responders and nonresponders were performed by using the Mann-Whitney test. RESULTS After therapy, K(trans), v(e), C(peak), slope, and AUC(60) decreased significantly (P = .02, .001, .002, .007, and .01, respectively). Tumor size and K(ep) were not significantly changed. Pretreatment K(trans) and K(ep) were significantly higher (P = .02 and .006, respectively) in tumors that showed marker response than in those that did not. A pretreatment K(trans) value (milliliters of blood per milliliter of tissue times minutes) of more than 0.78 mL/mL . min was 100% sensitive and 71% specific for subsequent tumor response. Semiquantative parameters and tumor size were not different between the groups. CONCLUSION Pretreatment K(trans) measurement in pancreatic tumors can predict response to antiangiogenic therapy. All perfusion parameters showed substantial reduction after 28 days of combined chemotherapy and antiangiogenic therapy.
