Immunotherapy for pancreatic cancer

Pancreatic cancer, a highly lethal cancer, has the lowest 5-year survival rate forseveral reasons, including its tendency for the late diagnosis, a lack of serologicmarkers for screening, aggressive local invasion, its early metastaticdissemination, and its resistance to chemotherapy/radiotherapy. Pancreaticcancer evades immunologic elimination by a variety of mechanisms, includinginduction of an immunosuppressive microenvironment. Cancer-associatedfibroblasts interact with inhibitory immune cells, such as tumor-associatedmacrophages and regulatory T cells, to form an inflammatory shell-like desmoplasticstroma around tumor cells. Immunotherapy has the potential to mobilizethe immune system to eliminate cancer cells. Nevertheless, althoughimmunotherapy has shown brilliant results across a wide range of malignancies,only anti-programmed cell death 1 antibodies have been approved for use inpatients with pancreatic cancer who test positive for microsatellite instability ormismatch repair deficiency. Some patients treated with immunotherapy whoshow progression based on conventional response criteria may prove to have adurable response later. Continuation of immune-based treatment beyond diseaseprogression can be chosen if the patient is clinically stable. Immunotherapeuticapproaches for pancreatic cancer treatment deserve further exploration, given theplethora of combination trials with other immunotherapeutic agents, targetedtherapy, stroma-modulating agents, chemotherapy, and multi-way combinationtherapies.

The predictability of T3 disease in staging MRI following prostate biopsy decreases in patients with high initial PSA and Gleason score

Asian Journal of Andrology 2011年第3期13卷 487-493,515页

作者： Young Hwii Ko Deuk Jae sung sung Gu kang Seok Ho kang Jeong Gu Lee Je Jong Kim Jun Cheon Department of Urology Korea University School of Medicine Seoul Korea Department of Radiology Korea University School of Medicine Seoul Korea

To obtain improved accuracy in predicting extracapsular extension （ECE） and seminal vesicle invasion （SVI）, we evaluated the variables affecting the predictability of staging magnetic resonance imaging （MRI, phased-array coil） and estimated their impact on accuracy between preoperative MRI staging and histological outcome. A total of 121 patients with localized or locally advanced prostate cancer who underwent robotic radical prostatectomy （RALP） were included. Following transrectal biopsy, all enrolled patients had undergone MRI for staging work-up. After RALP, only 43.8% （53/121） of the patients were matched with the MRI predicted stage. Compared to the matched group in the prediction of ECE, the unmatched group had significantly higher initial prostate-specific antigen （PSA, 12.8 ng m1-1 versus 8.1 ng m1-1, P=0.048）. In the prediction of SVI, initial PSA （8.1 ng ml- 1 versus 17.3 ng ml- 1, P=0.009） and biopsy Gleason score （6.5 versus 7.6, P=0.035） were significantly higher in the unmatched group. When applying clinical cutoffs of initial PSA of 10 and 20 ng ml-1, the accuracy of MRI in the prediction of ECE was decreased in the group with PSA over 20 ng ml- 1 （75.6, 64.5 and 37.5%, P=0.01）, and this group had significantly decreased accuracy of MRI in the prediction of SVI （91.5, 77.4 and 37.5%, P〈0.01）. Applying the clinical cutoff of a Gleason score of 7, the accuracy of MRI in the prediction of SVI was decreased in the higher G leason score group （93.9, 82.1 and 62.9%, P= 0.01）. Thus, for these patient groups, to obtain margin negativity during radical prostatectomy, operative findings, rather than post-biopsy MRI images, may provide substantial information, implying a clinical advantage in conducting MRI before prostate biopsy.
