In cancer patients showing nausea and vomiting, a number of factors can be considered as the cause including brain tumor, electrolyte imbalance, gastrointestinal diseases or types of chemotherapy agents and dose of the drugs. Though nausea and vomiting can be minimized through the use of various anti-emetic drugs, many people still suffer from severe nausea and vomiting with poor quality of life compared with patients who do not show significant nausea and vomiting. In this report, we introduce a case of a cancer patient who suffered from severe nausea and vomiting. The patient was female and 59 years old with NSCLC (non small cell lung cancer) with metastatic brain tumor. Though western conventional medical treatment was used to reduce the symptoms, persistent nausea and vomiting were noted during the admission period. Herbal decoction Gamibokryungbanha-tang was used for nausea and vomiting which were uncontrolled under conventional western medicine; the patient showed remarkable improvement in terms of frequency and severity of nausea and vomiting. Further study will be needed in order to determine the long-term effectiveness of oriental medical treatment on cancer patient with nausea and vomiting.
Purpose: No general consensus has been reached regarding the necessity of postoperative radiation therapy (PORT) and the optimal techniques of its application for patients with chest wall invasion (pT3cw) and node negative (NO) non-small cell lung cancer (NSCLC). We retrospectively analyzed the PT3cwN0 NSCLC patients who received PORT because of presumed inadequate resection margin on surgical findings. Materials and Methods: From Aug. 1994 till June 2000, 21 pT3cwN0 NSCLC patients received PORT at Samsung Medical Center; all of whom underwent curative on-bloc resection of the primary tumor plus the chest wall and regional lymph node dissection. PORT was typically stalled 3 to 4 weeks after operation using 6 or 10 MV X-rays from a linear accelerator. The radiation target volume was confined to the tumor bed plus the immediate adjacent tissue, and no regional lymphatics were included. The planned radiation dose was 54 Gy by conventional fractionation schedule. The survival rates were calculated and the failure patterns analyzed. Results: Overall survival, disease-free survival, loco-regional recurrence-free survival, and distant metastases-free survival rates at 5 years were 38.8$\%$, 45.5$\%$, 90.2$\%$, and 48.1$\%$, respectively. Eleven patients experienced treatment failure: six with distant metastases, three with intra-thoracic failures, and two with combined distant and intra-thoracic failures. Among the five patients with intra-thoracic failures, two had pleural seeding, two had in-field local failures, and only one had regional lymphatic failure in the mediastinum. No patients suffered from acute and late radiation side effects of RTOG grade 3 or higher. Conclusion: The strategy of adding PORT to surgery to improve the probability, not only of local control but also of survival, was justified, considering that local control was the most important component in the successful treatment of pT3cw NSCLC patients, especially when the resection margin was not adequate. The incidence and the severity of the acute and late side effects of PORT were markedly reduced, which contributed to improving the patients' qualify of life both during and after PORT, without increasing the risk of regional failures by eliminating the regional lymphatics from the radiation target volume.
Background: It is very important to determine an accurate staging of the non-small cell lung cancer(NSCLC) for an assessment of operability and it's prognosis. However, it is difficult to evaluate tumor involvement of mediastinal lymph nodes accurately utilizing noninvasive imaging modalities. PET is one of the sensitive and specific imaging modality. Unfortunately PET is limited use because of prohibitive cost involved with it's operation. Recently hybrid SPECT/PET(single photon emission computed tomography/positron emission tomography) camera based PET imaging was introduced with relatively low cost. We evaluated the usefulness of coincidence detection(CoDe) PET in the detection of metastasis to the mediastinal lymph nodes in patients with NSCLC. Methods: Twenty one patients with NSCLC were evaluated by CT or MRI and they were considered operable. CoDe PET was performed in all 21 patients prior to surgery. Tomographic slices of axial, coronal and sagittal planes were visually analysed. At surgery, mediastinal lymph nodes were removed and histological diagnosis was performed. CoDe PET findings were correlated with histological findings. Results: Twenty of 21 primary tumor masses were detected by the CoDe PET. Thirteen of 21 patients was correctly diagnosed mediastinal lymph node metastasis by the CoDe PET. Pathological N0 was 14 cases and the specificity of N0 of CoDe PET was 64.3%. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of N1 node was 83.3%, 73.3%, 55.6%, 91.7%, and 76.2% respectively. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of N2 node was 60.0%, 87.5%, 60.0%,87.5%, and 90.0% respectively. There were 3 false negative cases but the size of the 3 nodes were less than 1cm. The size of true positive nodes were 1.1cm, 1.0cm, 0.5cm respectively. There were 1 false positive among the 12 lymph nodes which were larger than 1cm. False positive cases consisted of 1 tuberculosis case, 1 pneumoconiosis case and 1 anthracosis case. Conclusion: CoDe PET has relatively high negative predictive value in the enlarged lymph node in staging of mediastinal nodes in patients with NSCLC. Therefore CoDe PET is useful in ruling out metastasis of enlarged N3 nodes. However, further study is needed including more number of patients in the future.
Background: In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. Methods: A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2016 were retrospectively reviewed, including 47 in the triple-port group and 26 in the single-port group. Statistical analysis was performed after propensity score matching. Patients were matched on a 1-to-1 basis. Results: Operative time and intraoperative blood loss in the triple-port group and the single-port group were similar ($189.4{\pm}50.8minutes$ vs. $205.4{\pm}50.6minutes$, p=0.259; $286.5{\pm}531.0mL$ vs. $314.6{\pm}513.1mL$, p=0.813). There were no cases of morbidity or mortality. No significant differences in complications or the total number of dissected lymph nodes were found between the 2 groups. In the single-port group, more mediastinal lymph nodes were dissected than in the triple-port group ($1.7{\pm}0.6$ vs. $1.2{\pm}0.5$, p=0.011). Both groups had 1 patient with bronchopleural fistula. Chest tube duration and postoperative hospital stay were shorter in the single-port group than in the triple-port group ($8.7{\pm}5.1days$ vs. $6.2{\pm}6.6days$, p=0.130; $11.7{\pm}6.1days$ vs. $9.5{\pm}6.4days$, p=0.226). However, the differences were not statistically significant. In the single-port group, the rate of conversion to multi-port VATS lobectomy was 11.5% (3 of 26). The rates of conversion to open thoracotomy in the triple-port and single-port groups were 7.7% and 3.8%, respectively (p=1.000). Conclusion: In comparison with the triple-port group, single-port VATS lobectomy showed similar results in safety and efficacy, indicating that single-port VATS lobectomy is a feasible and safe option for lung cancer patients.

Docetaxel is a taxoid antineoplastic drug, which is widely used to treat locally advanced or metastatic non-small cell lung cancer (NSCLC). Among the adverse dermatological reactions, nail disorders such as bending, onycholysis, hypoor hyperpigmentation are rare. We report a case of a 62-year-old male with advanced NSCLC (cT4N3M1, stage IV), who developed purulent discharge and onycholysis in the nail of all his fingers and the left great toe after five courses of anti-neoplastic chemotherapy, which included docetaxel (cumulative dose: $370mg/m^2$, 590 mg). Seven days after the final session of chemotherapy, the patient had become aware of discoloration and swelling of the nail beds with out pain. Three days later, greenish-yellow purulent discharge oozed out from the involved nails. Microbiologic studies revealed Pseudomonas aeruginosa. Intravenous and topical antibiotics (mupirocin) were applied. After 2 weeks, regrown nails were observed and the onycholysis had improved.
Aims: Mammalian target of rapamycin (mTOR) is master regulator of the PI3K/Akt/mTOR pathway and plays an important role in NSCLCs. Here we characterized mRNA and protein expression levels of mTOR and its functional associated molecules including PTEN, IGF-1R and 4EBP1 in surgically resected NSCLCs. Methods: Fifty-four patients with NSCLCs who underwent pulmonary resection were included in current study. mRNA levels of mTOR, PTEN, IGF-1R, and 4EBP1 were evaluated by RT-PCR and protein expression of mTOR, PTEN, and IGF-1R by immunohistochemistry (IHC). Association of expression of the relevant molecules with clinical characteristics, as well as correlations between mTOR and PTEN, 4EBP1 and IGF-1R were also assessed. Results: The results of RT-PCR showed that in NSCLCs, the expression level of mTOR increased, while PTEN, 4EBP1 and IGF-1R decreased. Statistical analysis indicated high IGF-1R expression was correlated with advanced clinical stage (stage III) and PTEN expression was reversely associated with tumor size (P=0.16). The results of IHC showed mTOR positive staining in 51.8% of cases, while IGF-1R positive staining was found in 83.3% and loss of PTEN in 46.3%. Protein expression of mTOR was correlated with its regulators, PTEN and IGF-1R, to some extent. Conclusions: Abnormal activation of mTOR signaling, high expression of IGF-1R, and loss of PTEN were observed in resected NSCLC specimens. The poor expression agreement of mTOR with its regulators, PTEN, and IGF-1R, implied that combination strategy of mTOR inhibitors with other targets hold significant potential for NSCLC treatment.
The following conclusions were obtained after bibliographic investigation on the therapy of lung cancer by western, oriental, and integrated oriental and western medicine. 1. Lung cancer is classified into small cell lung cancer(SCLC) or non small cell lung cancer(NSCLC) in the treatment by western medicine, and applied with the means of surgery, radiotherapy and chemotherapy alone or combined, depending on the stage and the symptom. 2. Treatment by oriental medicine includes the means of strengthening body resistance to dispel pathogenic factors(扶正祛邪), combined approach of reinforcement and expulsion(攻補兼施), and reinforcing both qi and blood(氣血雙補), depending on the initial, middle, and terminal stage. And also treatment based on differentiation of symptom(辨證施治) is applied according to the type of symptom; deficiency of qi of both lung and spleen(肺脾氣虛), heat symptom of lung by deficiency of yin(肺熱陰虛), stagnation of damp-phlegm and blood(濕痰瘀阻), stagnation of qi and blood(氣血瘀滯), deficiency of both qi and yin(氣陰兩虛). Single or combined herb drug is used according to the symptom. 3. Treatment by integrated oriental and western medicine improved survival rate and quality of life. It promoted recovery and improved survival rate in the patients receiving surgery. Integrated radiotherapy and oriental medicine treatment reduced adverse effect by radiotherapy and improved therapeutic effect and survival rate. Integrated chemotherapy with oriental medicine treatment reduced side effect by chemotherapy and improved quality of life and survival rate. These results suggest that therapy of lung cancer should be applied with integrated oriental and western medicine from diagnosis to treatment for promoting therapeutic effect. And further study on this therapy should be ensued.
Background : The aim of this study was to elucidate the mediastinal lymphatic drainage of nonsmall- cell lung cancer (NSCLC). Methods : We retrospectively analyzed the frequency of enlarged mediastinal lymph node (LN) in 256 NSCLC patients with N2 or N3 diseases on CT scan, especially with respect to the location of primary tumor. Results : In 57 patients with right upper lobe (RUL) tumors, right lower paratracheal LN (89.5%) was the most commonly enlarged, followed by subcarinal LN (54.4%). In 61 patients with left upper lobe (LUL) tumors, left lower paratracheal (70.5%) and subaortic LNs (52.5%) were commonly enlarged. Subcarinal LN enlargement without ipsilateral superior mediastinal LN enlargement was rarely found in both upper lobe tumors; RUL 8.8%, LUL 6.6%. In patients with right or left lower lobe (RLL or LLL) tumors, the most commonly enlarged LN was subcarinal; 88.2%, 65.7%, respectively. In RLL tumors with both subcarinal and superior mediastinal LN enlargements, the frequency of ipsilateral superior mediastinal LN involvement was similar to that of bilateral superior mediastinal involvement. In LLL tumors with both subcarinal and superior mediastinal LN enlargements, bilateral superior mediastinal involvement was more frequent than ipsilateral superior mediastinal involvement. Conclusion : The results of this study suggest that both upper lobe tumors are mainly drained directly to ipsilateral superior mediastinal LNs, and that both lower lobe lesions are drained to superior mediastinal LN via subcarinal LNs.
The nucleoside analogue gemcitabine (2', 2-difluorideoxycytide) is potential against a wide variety of solid tumors and considered to be one of the most active drugs in the treatment of non-small cell lung cancer (NSCLC). In this study, we investigated the signals of gemcitabine-induced apoptosis, especially in point of caspase pathway in A549. We exposed A549 cells to gemcitabine for dose/time dependent manner and the results showed that gemcitabine induced apoptotic cell death in a time/dose-dependent manner. We also treated to gemcitabine and Z-VAD-fmk as a pan-caspase inhibitor for 24 hours. Gemcitabine alone induced 35.3% cell death, and co-treatment with gemcitabine and Z-VAD-fmk induced 15.1% apoptotic cell death. Our results demonstrated that Z-VAD-fmk as a pan-caspase did not completely block the gemcitabine-induced apoptosis. Western blotting analysis showed that gemcitabine increased caspase-3, active caspase-8, p21 and p53 protein expressions in A549. Co-treatment with Z-VAD-fmk completely blocked caspase-3 and active caspase-8 protein expressions, but did not change the level of p21 and p53 protein expressions. Our data indicate that gemcitabine induced apoptosis through caspase-dependent and -independent pathways in A549.
Histone deacetylase inhibitor (HDACI) is a new promising candidate as an antineoplastic agent for the treatment of solid and hematologic malignancies. In order to evaluate cell death and to elucidate the related mechanism(s) in NSCLC cells after HDACI, sodium butyrate (SB), a representative HDACI, was used to treat H460 cells for 48 hrs. SB exposure resulted in a significant reduction of cell viability at concentrations below 7.5 mM, and about 50% of cell death occurred at 20 mM. The types of cell death induced by SB were both apoptosis and necrosis, evaluated by Annexin-V staining combined with propidium iodide. SB treatment significantly evoked G2/M cell cycle arrest and subsequently induced cell death with caspase-dependent manner. While ERK protein content was not altered after SB, phosphorylated forms of ERK were markedly reduced. Taken together, SB is significantly able to induce cell death in NSCLC cell line H460, and it is suggested that the reduction of ERK phosphorylation might be closely involved in the cancer cell death mechanism initiated by HDACI.
