To tailor the subsequent treatment and follow-up strategy,this study dynamically assessed the response to initial therapy in non-distant metastatic differentiated thyroid cancer (DTC) patients with intermediate and high risk. A total of 184 non-distant metastatic DTC patients (intermediate-risk 111 cases and high-risk 73 cases) were retrospectively enrolled in this study. Based on the results of initial response assessment (6-12 months after initial therapy),patients were divided into two groups:excellent response (ER) group (=113) and non-excellent response (non-ER) group (=71). We compared the differences in clinicopathological features between these 2 groups and evaluated the changes of dynamic response to therapy at the initial and final assessments after initial therapy in all patients. Compared with the ER group,the non-ER group showed a larger tumor size (=2771.500,=0.000),higher proportion of extrathyroidal invasion (=4.070,=0.044),and higher preablative-stimulated thyroglobulin levels (=1367.500,=0.000). ER was achieved in 31% of patients in the initial non-ER group [including indeterminate response (IDR) and biochemical incomplete response (BIR)] at the final follow-up only by thyroid stimulating hormone (TSH) suppression therapy,among which 63.6% were with intermediate risk (especially the patients with IDR) and 36.4% at high risk. In addition,5.2%(6/113) of patients in the initial ER group were reassessed as IDR,BIR,or even structural incomplete response at the end of the follow-up (among which one patient developed into cervical lymph node recurrence,as confirmed by pathology);the TSH level in these patients fluctuated at 0.56-10.35 μIU/ml and was not corrected in time during the follow-up after initial therapy. Some of non-distant metastatic DTC patients with intermediate and high risks who presented initial non-ER may achieve ER only by TSH suppression therapy over time;in contrast,the patients presented initial ER may develop into non-ER without normalized TSH suppression therapy. The dynamic risk assessment system may provide a real-time assessment of recurrence risk and tailor the subsequent treatment and follow-up strategies.

Gastric cancer (GC) is one of the most common tumor in the world, and remains a major public health problem and one of the leading causes of death. Recently many researches have demonstrated that systemic inflammatory response is associated with prognosis and response to therapy in gastric cancer, and the peripheral blood count test can partly reflect the systemic inflammatory response. Based on the peripheral blood count test, there are a lot of research regarding the relation between the platelet count (PLT), neutrophil, lymphocyte, white blood cell (WBC), neutrophil to lymphocyte ratio(NLR), platelet to lymphocyte ratio (PLR) with their prognostic role in gastric cancer. A high PLT and preoperative lymphocytopenia are both associated with increased lymph node metastasis, stage (III(+IIII(), serosal invasion (T3+T4) risk and poorer overall survival. Besides above, platelet monitoring following surgery can be applied to predict the recurrence for patients with GC that suffer preoperative high PLT but have restored PLT levels following resection. Moreover systemic inflammatory factors based on blood parameters, such as PLR, NLR and so on, have relation with the poor prognosis of patients with GC. Among them, high NLR is a negative predictor of prognosis in GC patients. However PLR remains inconsistent, while most researches demonstrated high PLR may be useful prognostic factor rather than independent prognostic factor. There are still some limitations which include various cut-off values, little of clinician attention, the uncertain mechanism, etc. Here we review the research progress in the prognostic role of the blood count test in gastric cancer.

OBJECTIVETo assess the value of detecting peripheral blood circulating tumor cells (CTCs) in the diagnosis and treatment of hepatocellular carcinoma (HCC).

METHODSA total of 296 patients diagnosed with HCC admitted in our department from July 2013 to January 2015 were analyzed, with 39 patients with benign liver disease serving as the control group. The distribution of CTCs in the peripheral blood of HCC patients were detected by CanPatrol(TM) CTCs, and its relationship with the clinical features and prognosis of the patients were analyzed.

RESULTSs CTCs were detected in 64.5% (191/296) of the HCC patients but in none of the control group (P<0.05). Positive CTCs in peripheral blood of HCC patients were significantly correlated with serum AFP level, tumor number, TNM stage, BCLC stage, portal vein tumor thrombus and metastasis (P<0.05). In 127 HCC patients receiving radical surgery, the patients positive for CTCs showed significantly shorter relapse-free survival time (P<0.05).

CONCLUSIONPositive CTCs in the peripheral blood may indicate a poor prognosis in HCC patients. CTCs may serve as a indicator for monitoring the prognosis of HCC.

OBJECTIVE: Fertility-sparing surgery (FSS) is becoming an important technique in the surgical management of young women with early-stage epithelial ovarian cancer (EOC). We retrospectively evaluated the outcome of laparoscopic FSS in presumed clinically early-stage EOC. METHODS: We retrospectively searched databases of patients who received laparoscopic FSS for EOC between January 1999 and December 2012 at Samsung Medical Center. Women aged < or =40 years were included. The perioperative, oncological, and obstetric outcomes of these patients were evaluated. RESULTS: A total of 18 patients was evaluated. The median age of the patients was 33.5 years (range, 14 to 40 years). The number of patients with clinically stage IA and IC was 6 (33.3%) and 12 (66.7%), respectively. There were 7 (38.9%), 5 (27.8%), 3 (16.7%), and 3 patients (16.7%) with mucinous, endometrioid, clear cell, and serous tumor types, respectively. Complete surgical staging to preserve the uterus and one ovary with adnexa was performed in 4 patients (22.2%). Two out of them were upstaged to The International Federation of Gynecology and Obstetrics stage IIIA1. During the median follow-up of 47.3 months (range, 11.5 to 195.3 months), there were no perioperative or long term surgical complications. Four women (22.2%) conceived after their respective ovarian cancer treatments. Three (16.7%) of them completed full-term delivery and one is expecting a baby. One patient had disease recurrence. No patient died of the disease. CONCLUSION: FSS in young patients with presumed clinically early-stage EOC is a challenging and cautious procedure. Further studies are urgent to determine the safety and feasibility of laparoscopic FSS in young patients with presumed clinically early-stage EOC.

The death of patients with gastric cancer is mainly due to its recurrence and metastasis, and circulating tumor cell (CTC) is the necessary condition of metastasis. As liquid biopsy, CTC detection has its certain clinical significance. The detection is required after enrichment because circulating tumor cells are rare. Many enrichment methods have been developed: methods based on physical characteristics of TCT, like density, size and dielectric properties and so on; immunogenicity, like Cell Search System; and microfluidic chip technology. The immunofluorescence is commonly used to identify CTC in gastric cancer and the isolated CTC can also be used for the following analysis on the level of nucleic acid, protein and gene regulation. Detection of CTC in gastric cancer is helpful to judge the prognosis, assess staging, monitor the curative effect and guide the development of drug. There are many challenges for clinical transformation of CTC: the lower enrichment efficiency, the less specific surface markers, the uncertain diagnostic efficiency and so on, but it also has the good research prospect because it is non-invasive, repeatable and can real-time monitor the condition and guide the clinical treatment compared with pathological biopsy. In this paper, the detection and identification methods, and clinical value of CTC in gastric cancer patients are reviewed.

Precision medicine is becoming the goal of translational research on colorectal cancer. Accurate molecular subtyping contributes to better guidance of clinical practice. The current TNM staging system of colorectal cancer is inadequate in terms of guiding clinical practice, such as the underestimation of prognosis of with stage II( and III( colorectal cancer TNM staging, and identification of high-risk and low-risk patients with stage II( colorectal cancer. Researchers from Europe and US have proposed a number of molecular subtypings with clinicopathological phenotypes and molecular phenotypes, which has certain practical significance and is beneficial to the choice of treatment regimen and targeted drugs. But the current results of subtyping research require further validations by clinical large scale multi-center trials. Based on precision medicine, molecular subtyping gradually reveals its clinical significance and is optimized through combining genomics with various clinical phenotypes, indicating its guidance for clinical practice, which is the inevitable course of precision medicine accomplishment. In recent years, there have been many new advances in colorectal cancer liver metastasis treatment. The prognosis of colorectal cancer patients undergoing resection of liver metastasis lesion is similar to those with stage III(. Early recurrence within 6 months after translational treatment and resection occurred in about one third of the patients with initially unresectable liver metastasis, and the overall survival was poor. Thus, an evaluation system should be established in order to avoid the strong therapy and strive for better quality of life in some patients. Individualized treatment for colorectal cancer is emphasized increasingly. Body fluid (peripheral blood and urine) marker detection is a recent research hotspot, including serum protein(polypeptide), plasma miRNA, circulating tumor cells and circulating nucleic acid.

BACKGROUND/AIMS: Primary non-ampullary duodenal adenocarcinomas (PNADAs) comprise <0.3% of gastrointestinal malignancies. The rarity of PNADA and poorly defined natural history often leads to a delayed correct diagnosis. This study was conducted to evaluate the clinical characteristics of PNADA and to identify its prognostic factors. METHODS: Data were collected by retrospectively reviewing the medical records of patients with PNADA managed at Gyeongsang National University Hospital from January 2000 to December 2014. Demographic, clinical, endoscopic, and pathological variables were investigated, and factors related to survival were analyzed. RESULTS: Twenty-seven patients with PNADA were identified, and their median age was 64.9+/-13.6 years with 16 (59.3%) being male. The majority of patients (25/27, 92.6%) were initially diagnosed during upper endoscopy with biopsies. The tumor was located on the 1st or 2nd portion of duodenum in 92.6% (25/27) of patients. At the time of diagnosis, 85.2% (23/27) had advanced diseases (stage III or IV); 48.2% (13/27) had distant metastasis. Median survival time was 12 months (1-93 months). One and 3-year survival rates were 48.1% and 33.3%, respectively. On multivariable analysis, total bilirubin > or =2 mg/dL (OR, 85.28; 95% CI, 3.77-1,938.79; p=0.005) and distant metastasis (OR, 26.74; 95% CI, 3.13-2,328.14; p=0.003) at the time of diagnosis were independent poor prognostic factors. CONCLUSIONS: The majority of patients were diagnosed at an advanced stage. Presence of distant metastasis was independent prognostic factor of PNADA together with elevated total bilirubin.

OBJECTIVETo study the treatment strategy and survival of patients with primary leiomyosarcoma of inferior vena cava (PIVCLMS).

METHODSClinical data of 12 cases with PIVCLMS admitted in Peking University People's Hospital from January 2006 to September 2014 were reviewed retrospectively. All cases were confirmed by pathology examination. Among them, there were 4 male and 8 female patients with a mean age of (54 ± 9) years old. Tumors arose from the inferior vena cava (IVC) upper segment in 5 patients, from the middle in other 7 patients. Cardiac extension was observed in 4 cases. Tumor resection was undertaken in 8 patients, the other 4 patients were inoperable. The series was analyzed to identify clinical outcome of surgical strategy and protective factors for patient survival.

RESULTSIn tumor resection group, 6 patients had radical resection and 2 underwent palliative resection. As for IVC reconstruction, caval wall resection with a direct suture was carried out in 6 patients or with prosthetic patch in 1 patient. The other 1 patient underwent a segment caval resection and prosthetic graft replacement in situ. In 4 cases of suprahepatic PIVCLMS cardiopulmonary bypass or perfusion by right atrial intubation was performed to assist bleeding control and maintain circulation stabilization, among them 1 patient survived for more than 101 months with no tumor recurrence or metastasis. Among the patients submitted to tumor resection 2 early postoperative deaths occurred, and another 2 patients had complications. All 4 patients submitted to non-resective operation (only neoplasm biopsy) died of PIVCLMS within 8 months. Except for 2 cases of early death, mean survival after tumor resection was (54 ± 40) months. Two patients presented local recurrence and hepatic metastasis at follow-up of 16 months and 68 months.

CONCLUSIONSTumor resection is the only therapy for PIVCLMS with an expectation for long-term survival. The applicant of cardiopulmonary bypass makes some inoperable indicated to tumor resection.

OBJECTIVE: To investigate the efficacy of submucosal resection by CO2 laser in the treatment of recurrent laryngeal papilloma and the effect on prognosis. METHOD: A total of 11 patients diagnosed as recurrent laryngeal papilloma were included in this review. Papilloma was marked before operation and checked under fibro-laryngoscope. Papilloma was resected completely including the submucosal tissure with CO2 laser or microequipment. In widespread papilloma, false membrane in raw surface were cleared 7-10 days after operation. Surgical specimens (including membrane) were detected by routine pathology, HPV typing and immunohistochemical pathologic examination. The patients were checked once a month in the first 3 months after operation, and then once for every 3 months. Once the hoarseness and other symptoms aggravated or the disease was recurrent, the patients were treated immediately. RESULT: HPV viral DNA was found in 10/11 cases, with HPV11 (7/11 cases) and HPV6 (3/11 cases). Cases with regards to follow-up, from 6 months to 1 year, 3 cases were followed up 1 year after operation, without recurrence. Five patients including 2 children were followed up 6 to 12 months after operation, without recurrence. Two children underwent 2 or 3 operations, were followed-up more than 6 months withouting recurrence. CONCLUSION Papilloma submucosal resection could decrease postoperative recurrence and is worth to be further investigated.

BACKGROUND/AIMS: The prognosis of pancreatic adenocarcinoma (PAC) is poor. The serum carbohydrate antigen 19-9 (CA 19-9) level has been identified as a prognostic indicator of recurrence and reduced overall survival. The aim of this study was to identify preoperative prognostic factors and to create a prognostic model able to assess the early recurrence risk for patients with resectable PAC. METHODS: A series of 177 patients with PAC treated surgically at the St. Andrea Hospital of Rome between January 2003 and December 2011 were reviewed retrospectively. Univariate and multivariate analyses were utilized to identify preoperative prognostic indicators. RESULTS: A preoperative CA 19-9 level >228 U/mL, tumor size >3.1 cm, and the presence of pathological preoperative lymph nodes statistically correlated with early recurrence. Together, these three factors predicted the possibility of an early recurrence with 90.4% accuracy. The combination of these three preoperative conditions was identified as an independent parameter for early recurrence based on multivariate analysis (p=0.0314; hazard ratio, 3.9811; 95% confidence interval, 1.1745 to 15.3245). CONCLUSIONS: PAC patient candidates for surgical resection should undergo an assessment of early recurrence risk to avoid unnecessary and ineffective resection and to identify patients for whom palliative or alternative treatment may be the treatment of choice.
