A total of 23 new cancer medicines or indication expansions were approved by the U. S. Food and Drug Administration in 2012. Among these, 12 are new molecular entities (NMEs)--new chemical or biological drugs approved for the first time for oncologic use--and 10 of these NMEs are molecular targeted agents. Among the 10 targeted agents, 4 are anti-angiogenesis agents and 2 are Bcr-Abl pathway inhibitors, targeting well established targets validated by previously approved agents such as bevacizumab (Avastin) or imatinib (Gleevec). Despite this progress, several questions remain: Do these newly approved agents provide sufficient treatment options to manage the broad spectrum of cancers we deal with in the clinic? Where will the next wave of new cancer drugs come from? Where should R&D efforts be invested to continue improve cancer treatment and management, especially for tumor types uniquely prevalent in China? This editorial and the review articles in this special issue of Chinese Journal of Cancer provide an in depth review of the progress and challenges in developing targeted cancer therapies, as well as an outlook of new research areas where near term breakthroughs are expected to overcome some of these challenges.

Since cancer-related pain is the worldwide problem,intrathecal drug delivery system (IDD)has been an effective pain management option for patients with chronic and cancer pain.Compared with the other ways,such as oral or intravenous infusion,the delivery of drugs into the intrathecal space provides superior analgesia with lower doses of analgesics to minimize side effects while significantly improve quality of life.Recently,besides traditional opioid (especially mainly morphine) for intrathecal,clinical experts have also found some other drugs could be used for IDD to control the cancer-related pain,and have observed their effect and related adverses.This article aims to provide a general overview of the development trend in this field.

To explore the stability of impact assay for determination of microorganism in indoor air, the comparisons of continued sampling times of 2-minute and 4-minute for monitoring on microorganism of indoor air were carried out with JWL- Ⅱ B multifunctiom air microorganison monitor in 11 hotels, public places of entertainment, barbar shops and beauty shops. The results showed that, under a same environmental condition, there was no significant differences between the data obtained by 2-minute monitoring and 4-minute monitoring (t=1.854, P＞0.05).It indicated that impact assay presented very good stability in detecting the microorganism of indoor air within certaindetecting duration.

Objective To investigate the preventive application of octreotide acetate for the prevention of complications and serum pancreatic amylase secrection after pancreatoduodenectomy(PD).Methods Fiftysix cases who underwent PD in our hospital were randomized into the observational group (n =28) and the control group (n =28).The control group received routine preoperative treatment including fasting,gastrointestinal decompression,nutritional support,maintenance of water,electrolyte balance and the use of antibiotics,postoperative routine parenteral nutrition and antibiotic therapy.In addition to the conventional treatment,the observational group received prophylactic application of octreotide acetate by subcutaneous injection of 0.1 mg each time,3 times a day,and 7 days for a cycle of treatment.Blood biochemical index and postoperative complications in the two groups were monitored.Results The serum amylase levels in the observational group and the control group were (304.63 ±62.21) U/L and (445.52 ±64.52) U/L respectively at the tenth day after treatment.The two groups are significantly different in the serum amylase level (t =2.243,P ＜ 0.05).The pancreatic juice,gastric juice and bile drainage of patients in the observational group and the control group were (46.83 ± 31.42) ml,(189.92 ± 59.64) ml,(178.94 ± 45.18) ml,and (69.84 ± 34.30)ml,(237.08 ±71.27) ml,(356.11 ±64.23) ml respectively.The observational group had significantly reduced digestive fluid drainage volume compared with the control group (t =3.219,2.276,4.618 respectively,P ＜0.05).Complications occurred in 3 patients of the observational group (including 1 case of pancreatic fistula,1 case of hemorrhage,and 1 case of gastric emptying delay),with an incidence of 10.71％ (3/28).Complications occurred in 12 cases of the control group (including 3 cases of pancreatic fistula,2 cases of hemorrhage,3 cases of bile leakage,2 cases of delayed gastric emptying,2 cases of peritoneal infection),with an incidence of 42.86％ (12/28).There was significant difference between two groups in the incidence of complications (x2 =4.293,P ＜ 0.05).Conclusion Prophylactic application of somatostatin in PD restrains the secretion of digestive juice,and plays a preventive role for postoperative complications.The routine prophylactic application of octreotide in PD is necessary.

Objective To explore the effect of pregnancy outcome with cervical cold knife conization in pa -tients with early stage cervical cancer .Methods 23 patients with cold knife conization and 21 patients with radical trachelectomy were collected .The pregnancy outcome and perinatal infants between the two groups were compared . Results The pregnancy rate was 82.6%in the observation group,71.4%in the control group,there was statistically significant difference(χ2 =8.654,P=0.002);the section rate was 37.5% in the observation group,30.8% in the control group,there was statistically significant difference (χ2 =9.645, P =0.000 );10 cases of term delivery (62.5%)and birth weight was(3.27 ±1.15)in the observation group,term delivery(69.2%)and birth weight was (2.81 ±0.96)in the control group,proportion and birth weight were statistically significant differences (χ2 =11.671, P=0.000)(t =9.683,P=0.000);there were statistical significance in the outcome of pregnancy (Fisher P=0.036)and perinatal infants(Fisher P=0.034)among patients with different cervical conization height;the relapse rate was 4.4% in observation group,9.5% in the control group,the relapse rate of the two groups had significant difference(Fisher P =0.039).Conclusion Compared with radical trachelectomy ,patients treated by cold knife conization has high pregnancy rate and high cesarean section rate ,which can influence the outcome of pregnancy and perinatal infants .

Objective: To establish a model of rat osteosarcoma in nude mice and to study its biological characteristics.Methods: Intact tumor pieces were inoculated into the right tibia of nude mice.The nude mice were killed at different time and the growth of tumor and metastasis were observed.Result: The tumor growth rate was 100%.From the first week to the second week after implantation it grew into outer tissue from tibia,and widely invaded Soft tissue on the third week.Pulmonary metastasis took place from the fourth week to the fifth week,and the nude mice died of cachexia and respiratory failure resulting from the widely whole pulmonary metastasis on the sixth week or so.Conclusion: The tumor growth rate is high.The model simulates the clinical process of human osteosarcoma,and could be a satisfactory model for studying osteosarcoma.

Objective To discuss the clinical effect on treating hysteromyoma with compound acetic acid gossypol tablets.Methods 50 patients who are diagnosed with hysteromyoma take compound acetic acid gossypol tablets 20mg after supper every day for 3 months.
