Green tea is a popular beverage and its health benefits are well known. However, inconsistent results have been reported in observational studies concerning the association between green tea consumption and the lung cancer risk. In this commentary, several methodological issues underlying the measurement of tea exposure are highlighted. The recommendations should be useful for designing and planning prospective cohort studies to ascertain the protective effect of green tea against lung cancer.

4.Overview of Asbestos Issues in Korea.
Journal of Korean Medical Science 2009;24(3):363-367
Asbestos is a carcinogen that causes diseases such as mesothelioma and lung cancer in humans. There was a sharp increase in the use of asbestos in Korea in the 1970s as Korea's economy developed rapidly, and asbestos was only recently banned from use. Despite the ban of its use, previously applied asbestos still causes many problems. A series of asbestos-related events that recently occurred in Korea have caused the general public to become concerned about asbestos. Therefore, it is necessary to take proper action to deal with asbestos-related events, such as mass outbreaks of mesothelioma among residents who lived near asbestos textile factories or asbestos mines. Although there have been no rapid increases in asbestos-related illnesses in Korea to date, such illnesses are expected to increase greatly due to the amount of asbestos used and long latency period. Decreasing the asbestos exposure level to levels as low as possible is the most important step in preventing asbestos-related illnesses in the next few decades. However, there is a lack of specialized facilities for the analysis of asbestos and experts to diagnose and treat asbestos-related illnesses in Korea; therefore, national-level concern and support are required.

OBJECTIVETo explore the methods of the treatment and the principles of the prevention of bronchus-pleural fistula (BPF) after pneumonectomy.
METHODSThe clinical data of 15 cases of BPF after pneumonectomy in 815 lung cancer cases treated from July 1999 to June 2006 were analyzed retrospectively.
RESULTSThe occurrence rate of BPF after right pneumonectomy was 3.9% (12/310), higher than 0.6% (3/505) of left pneumonectomy (P < 0.01). The occurrence rate of BPF in cases with positive cancer residues in stump of bronchus was 22.7% (5/22), higher than 1.3% (10/793) of the cases with negative stump of bronchus (P < 0.01). The occurrence rate of BPF in the cases received preoperative radio- or chemotherapy was 5.0% (6/119), higher than 1.3% (9/696) of the cases received operation only (P < 0.05). There were no BPF occurred in the 76 cases whose bronchial stump were covered with autogenous tissues. All of the cases diagnosed as BPF were undertaken either closed or open chest drainage. Two cases were cured by thoracentesis aspiration and infusion antibiotics repeatedly. Two cases were cured by blocking the fistula with fibrin glue after sufficient anti-inflammatory treatment and hypertonic saline flushing. Six cases were discharged with a stable condition after closed drainage only. One case was discharged with open drainage for long time and 1 case was cured by hypertonic saline flushing after failure to cover the BPF using muscle flaps. Three cases died of multi-organs functional failure.
CONCLUSIONSBPF are related to the bronchial stump management and positive or negative residue of tumor at the bronchial stump. Autogenous tissues covering of the bronchial stump is a effective method for decrease the rate of BPF and especially for those patients received preoperative radio- or chemotherapy and right pneumonectomy. It should be performed for early mild cases with repeated thoracentesis aspirations or blocking the fistula with fibrin glue together with antibiotics. Chest closed drainage immediately and flushing with hypertonic saline repeatedly are effective methods for BPF.

A 58-year-old female patient, diagnosed with adenocarcinoma of the lung, underwent percutaneous vertebroplasty at the L4 vertebral body due to painful spinal metastases. Because of deep venous thrombosis of the left femoral and iliac veins, an inferior vena cava filter had been placed before vertebroplasty. Bone cement migrated into the venous bloodstream and then was being trapped within the previously placed filter. This case illustrates that caval filter could capture the bone cement and prevent it from migrating to the pulmonary circulation.

BACKGROUND:
The incidence of pulmonary embolism (PE) in lung cancer patients who underwent surgery increased during the perioperative period, and prophylactic anticoagulation therapy was important part of enhanced recovery after surgery (ERAS). However, the timing of preventive anticoagulation in patients with lung cancer remained controversial. This study was designed to investigate the safety and efficacy of perioperative prophylactic anticoagulation therapy for lung cancer patients.
METHODS:
Retrospective research was conducted on 562 lung cancer patients who underwent video-assisted thoracoscopic (VATS) anatomic pulmonary resections in West China Hospital from June 2016 to December 2016. 56 patients were treated with low molecular weight heparin (LMWH) anticoagulation 12 hours before operation until discharge, while the other 506 patients were treated with LMWH 24 hours after operation until discharge. The postoperative chest drainage volume, postoperative bleeding, pulmonary embolism incidence, and respiratory complications were analyzed.
RESULTS:
(1) There were no significant differences in prothrombin time (PT), activated partial thromboplastin time (APTT) and international normalized ratio (INR) between the pre-operation prophylactic anticoagulation group (PRE group) [(11.5±3.9) s, (27.8±3.5) s, (0.96±0.06) s] and the post-operation prophylactic anticoagulation group (POST group) [(11.4±1.4) s, (28.3±4.0) s, (0.98±0.07) s] (P=0.796, P=0.250, P=0.137), and there was no significant difference in Caprini score between the PRE group (3.1±1.8) and the POST group (3.3±1.5) (P=0.104). (2) There were no significant differences in anesthesia time and intraoperative bleeding between PRE group [(130.2±53.9) min, (76.8±49.3) mL] and POST group [(142.2±56.5) min, (73.7±41.6) mL] (P=0.067, P=0.201). (3) The total drainage volume in 72 hours after operation in PRE group [(728.1±505.7) mL] was significantly higher than that of POST group [(596.4±373.5) mL] (P=0.005), while there were no significant differences between the two groups in total postoperative drainage volume [(1,066.8±1,314.6) mL vs (907.8±999.8) mL, P=0.203]. (4) There were no significant differences between the two groups in pulmonary embolism incidence (1.785% vs 0.019%, P=0.525) and postoperative bleeding rates (1.785% vs 0.039%, P=0.300). (5) There were no significant differences between PRE group and POST group in subcutaneous emphysema incidence (1.785% vs 1.581%, P=0.989) and pulmonary infection rates (14.285% vs 6.324%, P=0.085).
CONCLUSIONS
The clinical value of preoperative prophylactic anticoagulation is equal to postoperative prophylactic anticoagulation for lung cancer patients.

OBJECTIVEThe efficacies of the selective 5-hydroxytryptamine3 (5-HT3) antagonists--ramosetron (0.3 mg) and granisetron (3 mg) in treating acute chemotherapy-induced digestive system dysunction were compared.
METHODSA total of 111 patients were enrolled in a single-blind, randomised crossover study; with data from 98 were used to assess efficacy and data from 110 to assess the safety profile. Ramosetron or granisetron was given intraveneously 15 min befire chemotherpy.
RESULTSThe ability of ramosetron to prevent emesis, nausea and anorexia was similar to granisetron during the first 6 h following the administration of chemotherapy, ciplatin or doxorubicin. However, during the first 24 h after chemotherapy, significant differences between ramosetron and granisetron appeared: emetic episode (P = 0.068), nausea (P = 0.006), and anorexia (P = 0.048) remained lower in ramosetron-treated patients. The safety profile of ramosetron was similar to that of granisetron and adverse events in both groups were generally mild and transient.
CONCLUSIONRamosetron is more potent and longer-lasting than granisetron in preventing chemotherapy-induced digestive disturbances.
