The 7th UICC/AJCC Gastric Cancer TNM Staging System includes major revisions of pT and pN classification. The Japanese Classification and UICC/AJCC TNM System have reached consistency in staging of gastric cancer. There are some new topics of lymphadenectomy in the new guidelines. The new TNM system accepts the database from Japan and Korea and it will be more accurate to predict the prognosis of gastric cancer patients. The rationality of splenectomy, total bursectomy, dissection of No.13 and No.14 lymph nodes is still not very clear and needs more evidences. D2 lymphadenectomy is the recommended surgical approach both in Eastern and Western countries. The benefit of paraaortic lymphadenectmoy for selected patients needs further evidences as well. The international gastric cancer staging project will collect the data from 23 countries and the new staging system will be applicable worldwide.

Laparoscopic surgery for colorectal cancer was first adopted 16 years ago. There are various limitations in performing laparoscopic surgery including the technical complexity and question of positive impact on the long-term oncologic outcome. The purpose of this review is to outline the important issues surrounding the laparoscopic surgery for colorectal cancer based on the most recently published articles. The laparoscopic approach provides the advantages of an illuminated and magnified view, which may be superior to open surgery. There was no significant difference on the oncologic clearance, especially its proportion of positive radial margins to the number of harvested lymph nodes. In addition, laparoscopic surgery for colorectal cancer was associated with earlier recovery of bowel function, need for fewer analgesics, and with a shorter hospital stay compared to open surgery. Long-term oncologic outcome does not appear to be impaired by laparoscopic resection and local recurrence and disease specific survival has been reported to be similar for both laparoscopic and open surgery for colorectal cancer. Laparoscopic surgery for colorectal cancer is feasible and safe when performed by experienced surgeons. The oncologic results of many ongoing prospective randomized controlled trials are eagerly awaited.

Cancer has become the leading cause of mortality in the urban area of China. Whole body diffusion weighted imaging (WB-DWI), also known as virtual positron emission tomography, has gradually become accepted as an image tool in tumor localization, characterization, staging and monitoring response to therapy or tumor recurrence. Our article aimed to summarize the limited initial clinical use of WB-DWI in the referred area, and to analyze the most potential advantage of WB-DWI in therapeutic monitoring and tumor staging. WB-DWI as a highly sensitive, completely non-invasive, well-tolerated and low price technique has a promising furture in tumor assessment. Profound clinical study is necessary for its further application improvement.

OBJECTIVE: To estimate the clinical significance of target biopsy in clinical diagnosis, and accurate pathologic specimen acquisition of laryngeal lesion by using narrow band imaging (NBI) endoscopy. METHOD: A total of 156 cases of patients with laryngeal lesions were collected from the department of Otolaryngology Head and Neck Surgery of Tianjin Union Medical Center from Aug 2012 to Dec 2014. All patients were randomly divided into regular biopsy group and NBI target biopsy group. Image data were recorded and the patients' samples were biopsied. The pathologic diagnosis was used to evaluate the accuracy of regular biopsy and target biopsy. RESULT: Based on the pathologic diagnosis, the correct accurate pathologic specimen acquisition rates in NBI target pathology group at stage 0 (Tis), stage I and stage II laryngeal cancer diagnosis compliance rate were higher than those in regular biopsy group, stage 0 (Tis) (χ² = 22.00, P < 0.05), stage I (χ² = 8.33, P < 0.05) and stage II (χ² = 4.55, P < 0.05). CONCLUSION NBI endoscopy plays an important role in the clinical diagnosis and accurate pathologic specimen acquisition of laryngeal carcinoma and can be a regular means to detect laryngeal lesions in clinical.

The incidence of early gastric cancer (EGC) has increased to over 50% in Korea and Japan due to rapid advances in diagnostic instrumentation and increased use of mass screening. Considering the excellent prognosies of EGC patients, the quality of life of these patients after treatment has recently been emphasized. For the better quality of life, laparoscopic surgery has emerged as an alternative therapy for EGC patients. Since Kitano et al. first performed laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer in 1991, it has been performed worldwide, especially in Japan and Korea. A number of reports have presented the excellent short term outcomes; less pain, better cosmetics, faster recovery, and shorter hospital stay. However, there is little evidence of the oncological outcome of laparoscopic gastrectomy as a treatment modality for gastric cancer. Multi-center randomized controlled trials of laparoscopic versus open gastrectomy are needed to establish the future role of laparoscopic surgery in the treatment of patients with gastric cancer.

OBJECTIVESTo evaluate significance of clinical parameters in prostate cancer staging.

METHODSOne hundred and twelve patients of prostate cancer were diagnosed by transrectal ultrasound-guided prostate needle biopsies. These cases were staged by pathologic diagnosis, MRI and bone scan. Clinical significance of serum PSA, Gleason score of biopsy, percentage of positive biopsy cores in prostate cancer staging were evaluated.

RESULTSOf 112 patients, 30.4% (34/112) underwent radical retropubic prostatectomy. The serum PSA, Gleason score of biopsy and percentage of positive biopsy cores, were significant correlation with staging prostate cancer (r = 0.698, r = 0.674, r = 0.671, P < 0.001), and no significant difference between staging B and staging C (chi 2 = 2.675, P = 0.096; chi 2 = 0.704, P = 0.401). PSA in patients with stage D had significant difference with others (chi 2 = 5.135, P = 0.023; chi 2 = 4.593, P = 0.032). The sensitivity, specificity and accuracy of PSA were 76.7%, 50.0% and 71.4% respectively. Those of Gleason score and percentage of positive biopsy cores were 83.3%, 77.3%, 82.1% and 77.8%, 54.5%, 73.2% respectively.

CONCLUSIONSThe serum PSA, Gleason score of biopsy and percentage of positive biopsy cores had clinical significance in the staging of prostate cancer. Gleason score of biopsy in staging was more accurate than that of the other two parameters and the serum PSA can better predict prostate cancer metastasis.

With the apparently increasing incidence of endometrial carcinoma, much importance has been attached to the early and exact diagnosis of endometrial carcinoma. This article mainly focuses on diagnostic techniques of endometrial carcinoma, especially diagnostic hysteroscopy and its assessment of myometrial invasion as well as stage of endometrial carcinoma. Whether hysteroscopy increases the risk of microscopic extrauterine spread is also discussed in this article.
