Background: It remains controversial whether palliative primary tumor resection (PPTR) can provide survival benefits to the patients with metastatic colorectal cancer (mCRC) who have unresectable metastases. The aim of this study was to evaluate whether PPTR could improve the survival of patients with mCRC. Methods: We conducted a retrospective study on consecutive mCRC patients with unresectable metastases who were diagnosed at Sun Yat?sen University Cancer Center in Guangzhou, Guangdong, China, between January 2005 and December 2012. Overall survival (OS) and progression?free survival (PFS) after first?line chemotherapy failure were compared between the PPTR and non?PPTR patient groups. Results: A total of 387 patients were identified, including 254 who underwent PPTR and 133 who did not. The median OS of the PPTR and non?PPTR groups was 20.8 and 14.8 months (P < 0.001), respectively. The median PFS after first?line chemotherapy was 7.3 and 4.8 months (P < 0.001) in the PPTR and non?PPTR groups, respectively. A larger proportion of patients in the PPTR group (219 of 254, 86.2%) showed local progression compared with that of patients in the non?PPTR group (95 of 133, 71.4%; P < 0.001). Only patients with normal lactate dehydrogenase (LDH) levels and with carcinoembryonic antigen (CEA) levels <70 ng/mL benefited from PPTR (median OS, 22.2 months for the PPTR group and 16.2 months for the non?PPTR group; P < 0.001). Conclusions: For mCRC patients with unresectable metastases, PPTR can improve OS and PFS after first?line chemo?therapy and decrease the incidence of new organ involvement. However, PPTR should be recommended only for patients with normal LDH levels and with CEA levels <70 ng/mL.

Autophagy is a catabolic process involving the degradation of a cell's own proteins and organelles and the subsequent recycle of cellular products. Despite the fact that autophagy helps maintain survival, excessive autophagy can lead to autophagic cell death. Recent researches showed that autophagy played an important role in the development, progression and treatment of colorectal cancer;however, the exact mechanisms of autophagy and its effect on chemotherapy and radiotherapy are still under debate.

Few studies of cetuximab on patients with gastric and esophageal cancer were available now.The disease control rate was 72.7%～92%,OS was 9.5～16.6months,PFS/was 6.2～11 months among first-line setting with cetuximab-contained regimens.And cetuximab shown in second-line regimen setting overcome the resistance of irinotecan and docetaxel.The pCR was 13%～65% when cetuximab was used as induction treatment combined with concurrent chemoradiation.18F-FDG-PET was a potential method to predictthe efficacy of cetuximab-contained regimens,however,status of Kras gene had no predictive value.

Objective To explore the relationship between the expression of P53 protein and the radiosensitivity in patients with advanced maxillary squamous cell carcinoma.Methods An immunohistochomical method wag used to detect the expression of P53 protein in patients with advanced maxillary squamous cell carcinoma.The follow up time was 2 years.The local recurrence of the patients having been treated with radical surgery and affiliated radiotheraphy were analyzed.Results The overexpression of P53 protein in 26 cages was 65.4% (17/26).In the P53 overexpression group,the local recurrence after systiem therapy wag occurred in one case within 6 months,6 cages between 7～12 months.3 cages between 13～18 months and 2 cases between 19～24 months.In the P53 low expression group,there were no recurrence within 6 and 12 months and one case ocurred within 18 months.5 cages between 19～24 months.The difference of recurrence within 18 months after system therapy between the expression of P53 Wag statistically significant(P＜0.05),but it Wag not significant for those within 24 months(P＞0.05).Conclusions The expression of P53 protein Wag correlated with the radiosensitivity in patient with advaneed maxillary squamous cell carciaoma,especially for the resid.rod cells in mitosis phase.The affiliated radiotherapy after radical surgery Wag limited effect.

Objective: To explore the IL\|5 values in the tissue and secretion of nasal polyp. Methods: The concentrations of IL\|5, either in tissue homogenate or in nasal secretion, were measured by ELISA. The values of total protein in tissue homogenate were measured by Bradford colorimetry. In this study, 31 cases with nasal polyp, 8 patients with perennial allergic rhinitis (PAR), 11 cases with chronic sinusitis (CS) and 6 control cases were chosen. Results: ① In tissue homogenate, the IL\|5 concentrations of nasal polyp were higher than that in CS or control group (P＜0.001). ② In nasal secretion, IL\|5 values of both nasal polyp and PAR group were significantly higher than that in CS or control group (P＜0.05). ③ When all cases or only patients with nasal polyp were taken as the subjects, the Pearson correlation coefficient were 0.70, 0.66 respectively. Conclusions: IL\|5 values, both in tissue homogenate and nasal secretion, are significantly higher, which suggested that there were a close relationship between IL\|5 and nasal polyp, and IL\|5 play a key role in the formation of nasal polyp.

Objective To investigate a method to detect the sentinel lymph nodes(SN) of thyroid papillary carcinoma and its predictive value for cervical metastasis of carcinoma. Methods Intraoperative methylene blue dye mapping was performed in 24 cases of thyroid papillary carcinoma. The coincidence rate of frozen section pathology and routine section pathology of SN was observed,and the predictive value of SN for (metastasis) of the cervical lymph nodes was noted. Results SN was successfully detected in 21(87.5%) of 24 cases. The average number of SN was 3 nodes. There was one false negative case, the false negative rate was 4.8%(1/24), and no false positive cases were found. The predictive value of sentinel lymph nodes to (cervical) lymph node metastasis was 83.3%.Conclusions Methylene blue staining to identify sentinel lymph nodes could accurately predict the status of cervical lymph node metastasis of thyroid papillary carcinoma.
