Abstract
Background Anaplastic lymphoma kinase (ALK) inhibition using crizotinib has become the standard of care in advanced ALK-rearranged non-small cell lung cancer (NSCLC), but the treatment outcomes and duration of response vary widely. Echinoderm microtubule-associated protein-like 4 (EML4)-ALK is the most common translocation, and the fusion variants show different sensitivity to crizotinib in vitro. However, there are only limited data on the specific EML4-ALK variants and clinical responses of patients to various ALK inhibitors. Patients and methods By multiplex reverse-transcriptase PCR, which detects 12 variants of known EML4-ALK rearrangements, we retrospectively determined ALK fusion variants in 54 advanced ALK rearrangement-positive NSCLCs. We subdivided the patients into two groups (variants 1/2/others and variants 3a/b) by protein stability and evaluated correlations of the variant status with clinical responses to crizotinib, alectinib, or ceritinib. Moreover, we established the EML4-ALK variant-expressing system and analyzed patterns of sensitivity of the variants to ALK inhibitors. Results Of the 54 tumors analyzed, EML4-ALK variants 3a/b (44.4%) was the most common type, followed by variants 1 (33.3%) and 2 (11.1%). The 2-year progression-free survival (PFS) rate was 76.0% [95% confidence interval (CI) 56.8-100] in group EML4-ALK variants 1/2/others versus 26.4% (95% CI 10.5-66.6) in group variants 3a/b (P = 0.034) among crizotinib-treated patients. Meanwhile, the 2-year PFS rate was 69.0% (95% CI 49.9-95.4) in group variants 1/2/others versus 32.7% (95% CI 15.6-68.4) in group variants 3a/b (P = 0.108) among all crizotinib-, alectinib-, and ceritinib-treated patients. Variant 3a- or 5a-harboring cells were resistant to ALK inhibitors with >10-fold higher half maximal inhibitory concentration in vitro. Conclusion Our findings show that group EML4-ALK variants 3a/b may be a major source of ALK inhibitor resistance in the clinic. The variant-specific genotype of the EML4-ALK fusion allows for more precise stratification of patients with advanced NSCLC.

Abstract
Clostridium difficile remains the leading cause of health care-associated infectious diarrhea, and its incidence and severity are increasing in liver transplant recipients. Several known risk factors for C difficile infection (CDI) are inherently associated with liver transplantation, such as severe underlying illness, immunosuppression, abdominal surgery, and broad-spectrum antibiotic use. We conducted a single-center retrospective case control study to characterize risk factors for CDI among patients who received a liver transplant from January 2008 to December 2012. We also examined the associations of post-transplantation CDI with transplant outcomes. Cases were defined as having diarrhea with a positive test for C difficile by either toxin A/B enzyme immunoassay (EIA) or glutamate dehydrogenase EIA and polymerase chain reaction within 1 year after transplantation. Sixty-five consecutive patients were evaluated, of which 15 (23%) developed CDI. The median time from transplantation to CDI diagnosis was 65 days (interquartile range [IQR] 13-208) and more than one-half (53%) had severe infection. Risk factors that were associated with CDI among liver transplant recipients included: (1) previous history of CDI (20% vs 0%; P = .001); (2) exposure to proton-pump inhibitor therapy (93% vs 60%; P = .015); (3) antimicrobial therapy before transplantation (47% vs 18%; P = .039); (4) a prolonged length of stay before transplantation (1 day [IQR, 1-19] vs 1 day [IQR, 0-1]; P = .028); and (5) chronic kidney disease (53% vs 20%; P = .011). There was no significant differences in patient survivals at 6 months (93% vs 96%; P = .67) and 12 months (87% vs 94%; P = .35) among CDI case and control subjects, respectively.

Abstract
INTRODUCTION Sclerosing mucoepidermoid carcinoma of the salivary gland is a rare subtype of mucoepidermoid carcinoma. The most common site of sclerosing mucoepidermoid carcinoma of the salivary glands is the parotid gland, followed by the submandibular gland, and the minor salivary glands. OBSERVATION Here we report the first case of sclerosing mucoepidermoid carcinoma of the sublingual gland. DISCUSSION Clinicians should consider sclerosing mucoepidermoid carcinoma in the differential diagnosis of salivary gland neoplasm. Surgical excision with clear margins seems to be a sufficient initial treatment option for sclerosing mucoepidermoid carcinoma of the salivary gland.

Abstract
The performances of acute physiology and chronic health evaluation (APACHE) II and simplified acute physiology score (SAPS) II have previously been evaluated in acute organophosphate poisoning. We aimed to compare the performance of the SAPS III with those of the APACHE II and SAPS II, as well as to identify the best tool for predicting case fatality using the standardized mortality ratios (SMRs) in acute organophosphate poisoning. A retrospective analysis of organophosphate poisoning was conducted. The APACHE II, SAPS II, and SAPS III were calculated within 24 h of admission. Discrimination was evaluated by calculating the area under the receiver operating characteristic curve (AUROC). The SMRs were calculated as 95% confidence intervals (CIs). In total, 100 cases of organophosphate poisoning were included. The in-hospital case fatality was 19%. The median scores of the APACHE II, SAPS II, and SAPS III were 20.0 (10.0–27.0), 41.0 (28.0–54.8), and 53.0 (36.3–68.8), respectively. The AUROCs were not significantly different among the APACHE II (0.815; 95% CI, 0.712–0.919), SAPS II (0.820; 95% CI, 0.719–0.912), and SAPS III (0.850; 95% CI, 0.763–0.936). Based on these scores and in-hospital case fatality, the SMRs for the APACHE II, SAPS II, and SAPS III were 1.01 (95% CI, 0.50–2.72), 1.01 (95% CI, 0.54 -2.78), and 0.98 (95% CI, 0.33–1.99), respectively. The SAPS III provided a good discrimination and satisfactory calibration in acute organophosphate poisoning. It was therefore a useful tool in predicting case fatality in acute organophosphate poisoning, similar to the APACHE II and SAPS II.

Abstract
Knee osteoarthritis (KOA) is a common disease in middle-aged and elderly people. Pain is the chief complaint of symptomatic KOA and a leading cause of chronic disability, which is most often found in medial knees. The aim of this study is to evaluate the efficacy of pain relief and functional improvement in KOA patients treated with ultrasound-guided adductor canal block (ACB).This is a 3-month retrospective case-controlled comparative study. Two hundred patients with anteromedial knee pain owing to KOA that was unresponsive to 3-month long conservative treatments. Ninety-two patients received ACB with 9 mL of 1% of lidocaine and 1 mL of 10 mg triamcinolone acetonide (ACB group), and 108 continued conservative treatments (control group). The main outcome measure was visual analog scale (VAS) of the average knee pain level for the past one week. Secondary outcomes were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the timed up and go test, numbers of analgesic ingestion per day, and opioid consumption per day.During the 3-month follow-up, 86 patients in ACB group and 92 in control group were analyzed. There was no significant difference, with the exception of the duration of symptoms, between the 2 groups in age, sex, body mass index, and Kellgren-Lawrence grade. Repeated-measures analysis of variance and post hoc tests showed improvement of VAS (at month 1), WOMAC (at month 1), and opioid consumption per day (at month 1 and 2) in ACB group. No adverse events were reported.To our knowledge, this is the first study to assess the efficacy of ACB for patients with KOA. ACB is an effective and safe treatment and can be an option for patients who are either unresponsive or unable to take analgesics.

Abstract
OBJECTIVE To evaluate the correlations between subacromial bursitis (bursal thickening and effusion) on ultrasonography and its response to subacromial corticosteroid injection in patients with rotator cuff disease. DESIGN Prospective, longitudinal comparison study. SETTING University-affiliated tertiary care hospital. PARTICIPANTS Patients with rotator cuff disease (N=69) were classified into 3 groups based on ultrasonographic findings; (1) normative bursa group (group 1, n=23): bursa and effusion thickness <1mm; (2) bursa thickening group (group 2, n=22): bursa thickness >2mm and effusion thickness <1mm; and (3) bursa effusion group (group 3, n=24): bursa thickness <1mm and effusion thickness >2mm. INTERVENTION A single subacromial injection with 20mg of triamcinolone acetonide. MAIN OUTCOME MEASURES Visual analog scale (VAS) of shoulder pain, Shoulder Disability Questionnaire (SDQ), angles of active shoulder range of motion (flexion, abduction, external rotation, and internal rotation), and bursa and effusion thickness at pre- and posttreatment at week 8. RESULTS There were no significant differences between the 3 groups in demographic characteristics pretreatment. Groups 2 and 3 showed a significant difference compared with group 1 in changes on the VAS and abduction; group 3 showed a significant difference compared with group 1 in changes of the SDQ, internal rotation, and external rotation; and all groups showed significant differences when compared with each other (groups 1 and 3, 2 and 3, and 1 and 2) in changes of thickness. CONCLUSIONS A patient with ultrasonographic observation of subacromial bursitis, instead of normative bursa, can expect better outcome with subacromial corticosteroid injection. Therefore, we recommend a careful selection of patients using ultrasonography prior to injection.

Abstract
BACKGROUND AND PURPOSE High-resolution MR imaging has recently been introduced as a promising diagnostic modality in intracranial artery disease. Our aim was to compare high-resolution MR imaging with digital subtraction angiography for the characterization and diagnosis of various intracranial artery diseases. MATERIALS AND METHODS Thirty-seven patients who had undergone both high-resolution MR imaging and DSA for intracranial artery disease were enrolled in our study (August 2011 to April 2014). The time interval between the high-resolution MR imaging and DSA was within 1 month. The degree of stenosis and the minimal luminal diameter were independently measured by 2 observers in both DSA and high-resolution MR imaging, and the results were compared. Two observers independently diagnosed intracranial artery diseases on DSA and high-resolution MR imaging. The time interval between the diagnoses on DSA and high-resolution MR imaging was 2 weeks. Interobserver diagnostic agreement for each technique and intermodality diagnostic agreement for each observer were acquired. RESULTS High-resolution MR imaging showed moderate-to-excellent agreement (interclass correlation coefficient = 0.892-0.949; κ = 0.548-0.614) and significant correlations (R = 0.766-892) with DSA on the degree of stenosis and minimal luminal diameter. The interobserver diagnostic agreement was good for DSA (κ = 0.643) and excellent for high-resolution MR imaging (κ = 0.818). The intermodality diagnostic agreement was good (κ = 0.704) for observer 1 and moderate (κ = 0.579) for observer 2, respectively. CONCLUSIONS High-resolution MR imaging may be an imaging method comparable with DSA for the characterization and diagnosis of various intracranial artery diseases.

Abstract
OBJECTIVE To determine the efficacy of polydeoxyribonucleotide (PDRN) injection for rotator cuff disease (RCD). DESIGN Case-controlled, retrospective, comparative study. SETTING Outpatient clinic at a university-affiliated tertiary care hospital. PARTICIPANTS Patients (N=106) with chronic nontraumatic refractory RCD who were unresponsive to at least 1 month of conservative treatment: 55 patients received PDRN injection (PDRN group) and 51 continued conservative treatment (control group). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Shoulder Pain and Disability Index, score on a visual analog scale of the average shoulder pain level, number of analgesic ingestions per day, isometric strength of shoulder abductor, active range of motion (flexion, abduction, internal rotation, external rotation), and maximal tear size of tendon on ultrasonography at pretreatment and 3 and 6 months postinjection. RESULTS There was no significant difference between the 2 groups in terms of age, sex, shoulder affected, duration of symptoms, and ultrasonographic findings at pretreatment. Compared with the control group, the treatment group showed a significant improvement in Shoulder Pain and Disability Index, visual analog scale score, and number of analgesic ingestions per day. However, there was no difference in isometric strength, active range of motion, and maximal tear size of tendon. No adverse events were reported. CONCLUSIONS To our knowledge, this is the first study to assess the efficacy of PDRN injection for patients with RCD. The PDRN injection group showed improvement in pain and subjective disability in patients with RCD and continued to show improvement for 3 months thereafter; the PDRN injection can be an optional treatment for patients with chronic RCD who show no response to other treatments.

Abstract
The effect of repetitive transcranial magnetic stimulation on kinesthetic perception, when applied to the somatosensory cortex, was examined. Further, the facilitatory and inhibitory effects of repetitive transcranial magnetic stimulation using different stimulation frequencies were tested. Six female (M age = 32.0 years, SD = 6.7) and nine male (M age = 32.9 years, SD = 6.6) participants were asked to perceive the tendon vibration illusion of the left wrist joint and to replicate the illusion with their right hand. When comparing changes in the corresponding movement amplitude and velocity after three different repetitive transcranial magnetic stimulation protocols (sham, 1 Hz inhibitory, and 5 Hz facilitatory repetitive transcranial magnetic stimulation), the movement amplitude was found to decrease with the inhibitory repetitive transcranial magnetic stimulation, while the movement velocity respectively increased and decreased with the facilitatory and inhibitory repetitive transcranial magnetic stimulation. These results confirmed the modulating effects of repetitive transcranial magnetic stimulation on kinesthetic perception in a single experimental paradigm.

Abstract
Investigating the chemical ecology of agricultural systems continues to be a salient part of integrated pest management programs. Apple maggot fly, a key pest of apple in eastern North America, is a visual specialist with attraction to host fruit-mimicking cues. These cues have been incorporated into red spherical traps used for both monitoring and behaviorally based management. Incorporating generalist or specialist olfactory cues can potentially increase the overall success of this management system. The primary aim of this study was to evaluate the attractiveness of a generalist olfactory cue, ammonium carbonate, and the specialist olfactory cue, a five-component apple volatile blend, when included as a component of a red attracticidal sphere system. Secondly, we assessed how critical it was to maintain minimal deviation from the optimal, full-round specialist visual stimulus provided by red spheres. Finally, attracticidal spheres were deployed with specialist olfactory cues in commercial apple orchards to evaluate their potential for effective management of apple maggot. Ammonium carbonate did not increase residency, feeding time, or mortality in the laboratory-based trials. Field deployment of specialist olfactory cues increased apple maggot captures on red spheres, while the generalist cue did not. Apple maggot tolerated some deviation from the optimal visual stimulus without reducing captures on red spheres. Attracticidal spheres hung in perimeter trees in orchards resulted in acceptable and statistically identical levels of control compared with standard insecticide programs used by growers. Overall, our study contributes valuable information for developing a reliable attract-and-kill system for apple maggot.

Abstract
PURPOSE Postoperative exercises may increase load on repaired tendons. Differences in the activity of the rotator cuff muscles were assessed during several different types of passive shoulder and active elbow exercises. METHODS In 15 healthy subjects, passive forward flexion of the shoulder was performed using a table, pulley and rope, and a cane, and external rotation was performed using a cane and a wall. The active elbow flexion-extension exercise was also performed while holding the upper arm with the contralateral hand. Activation amplitudes of the supraspinatus, infraspinatus and subscapularis muscles were evaluated using electromyography with fine wires. RESULTS During passive forward flexion, the supraspinatus and infraspinatus muscles exhibited lower activity when using a table compared with a cane (both P < 0.01) and a pulley and rope (both P < 0.05). Flexion of <90° decreased supraspinatus activation compared with 170° (P = 0.047). During external rotation of the shoulder while using the cane and wall, there was no difference in the activity of any muscles. Electromyographic activity during the active elbow exercise was lower in the supraspinatus while holding the upper arm (P = 0.018). CONCLUSION The table sliding exercise may reduce stress on the rotator cuff during passive forward flexion more than the other exercises do. Decreasing the range of motion to less than 90° in forward flexion activated the supraspinatus less. Moreover, movement of the elbow can be performed holding the upper arm to activate the rotator cuff to a lesser extent. LEVEL OF EVIDENCE Prognostic study, Level II.

Abstract
Dolutegravir is a preferred antiretroviral drug for human immunodeficiency virus (HIV)-infected patients following solid organ transplantation. It has potent antiretroviral activity and does not interact with calcineurin inhibitors. We describe a case of an HIV-infected kidney transplant patient, who was noted to have a rising serum creatinine following initiation of dolutegravir. At first, an acute rejection episode was suspected, but this finding was later attributed to inhibition of creatinine secretion by dolutegravir. We suggest that an awareness of this potential effect of dolutegravir is important for providers who take care of HIV-positive kidney transplant recipients, in order to prevent potentially unnecessary testing.

Abstract
The RENO experiment has analyzed about 500 live days of data to observe an energy dependent disappearance of reactor ν[over ¯]_{e} by comparing their prompt signal spectra measured in two identical near and far detectors. In the period between August of 2011 and January of 2013, the far (near) detector observed 31 541 (290 775) electron antineutrino candidate events with a background fraction of 4.9% (2.8%). The measured prompt spectra show an excess of reactor ν[over ¯]_{e} around 5 MeV relative to the prediction from a most commonly used model. A clear energy and baseline dependent disappearance of reactor ν[over ¯]_{e} is observed in the deficit of the observed number of ν[over ¯]_{e}. Based on the measured far-to-near ratio of prompt spectra, we obtain sin^{2}2θ_{13}=0.082±0.009(stat)±0.006(syst) and |Δm_{ee}^{2}|=[2.62_{-0.23}^{+0.21}(stat)_{-0.13}^{+0.12}(syst)]×10^{-3} eV^{2}.

[PMID: 26757425 PMCID: PMC4716547 DOI: 10.1038/bjc.2015.438] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2015] [Revised: 11/15/2015] [Accepted: 11/22/2015] [Indexed: 12/31/2022] Open
Abstract
Background: Male pattern baldness is positively associated with androgens as well as insulin-like growth factor 1 (IGF-1) and insulin, all of which are implicated in pathogenesis of colorectal neoplasia. Methods: From 1992 through 2010, we prospectively followed participants in the Health Professionals Follow-Up Study. Hair pattern at age 45 years was assessed at baseline with five image categories (no baldness, frontal-only baldness, frontal-plus-mild-vertex baldness, frontal-plus-moderate-vertex baldness, and frontal-plus-severe-vertex baldness). Cancer analysis included 32 782 men and used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Restricted to men who underwent at least one endoscopy over the study period, adenoma analysis included 29 770 men and used logistic regressions for clustered data to estimate odds ratios (ORs) and 95% CIs. Results: Over the mean follow-up of 15.6 years, 710 cases of colorectal cancer (478 for colon, 152 for rectum, and 80 unknown site) developed. Significantly increased risks associated with frontal-only baldness and frontal-plus-mild-vertex baldness relative to no baldness were observed for colon cancer with respective HR being 1.29 (95% CI, 1.03–1.62) and 1.31 (95% CI, 1.01–1.70). Over the 19-year study period, 3526 cases of colorectal adenoma were detected. Evidence for an increased risk of colorectal adenoma relative to no baldness was significant with frontal-only baldness (OR, 1.16; 95% CI, 1.06–1.26) and borderline insignificant with frontal-plus-severe-vertex baldness (OR, 1.14; 95% CI, 0.98–1.33). Conclusions: Subtypes of male pattern baldness at age 45 years were positively associated with colorectal neoplasia. Future studies are warranted to confirm our results and to determine the predictive value of male pattern baldness to identify those at high risk for colorectal neoplasia.

Abstract
UNLABELLED The aims of this study were to report functional outcomes of salvage procedures for patients with cerebral palsy (CP) who have chronic dislocation of the hip using validated scoring systems, and to compare the results of three surgical techniques. We reviewed 37 patients retrospectively. The mean age at the time of surgery was 12.2 years (8 to 22) and the mean follow-up was 56 months (24 to 114). Patients were divided into three groups: 14 who underwent proximal femoral resection arthroplasty (PFRA group 1), ten who underwent subtrochanteric valgus osteotomy (SVO group 2), and 13 who underwent subtrochanteric valgus osteotomy with resection of the femoral head (SVO with FHR group 3). All patients were evaluated using the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) and the Pediatric Quality of Life Inventory (PedsQL). Significant improvements occurred in most CPCHILD and PedsQL subsection scores following surgery in all patients, without significant differences between the groups. There were 12 post-operative complications. Less severe complications were seen in group 1 than in groups 2 and 3. Salvage surgery appears to provide pain relief in patients with CP who have painful chronic dislocation of the hip. The three salvage procedures produced similar results, however, we recommend the use of PFRA as the complications are less severe. TAKE HOME MESSAGE Salvage surgery can be of benefit to patients with CP with chronic painful hip dislocation, but should be limited to selected patients considering complications.

Abstract
Despite clear consensus and strong recommendations, vaccination rates of kidney transplant (KT) recipients have remained below targets. As vaccination is most effective if it is given prior to transplantation and the initiation of immunosuppression, patients should ideally have their vaccination status assessed and optimized in the pre-transplant period. We performed a retrospective chart review to characterize vaccination rates and factors associated with gaps in vaccination in a single-center population of waitlisted patients being evaluated for kidney transplantation. We evaluated 362 KT patients. Three-quarters were receiving dialysis at the time of evaluation. Immunization rates were low with 35.9% of patients having completed vaccination for Pneumococcus, 55% for influenza, 6.9% for zoster, and 2.5% for tetanus. On multivariable analysis, patients who received other vaccines, including influenza, tetanus, or zoster vaccine (odds ratio [OR] 10.55, 95% confidence interval [CI] 5.65-19.71) were more likely to receive pneumococcal vaccine. Blacks (OR 0.24, 95% CI 0.12-0.47) were less likely to receive pneumococcal vaccine compared to whites. Patients on dialysis, and those active on the waiting list were more likely to receive pneumococcal vaccine than other groups (OR 2.81, 95% CI 1.44-5.51, and OR 1.84, 95% CI 1.08-3.14, respectively). We found that the overall immunization rate against common vaccine-preventable infections was low among patients evaluated for kidney transplantation. A significant gap remains between recommendations and vaccine uptake in clinical practice among this high-risk population.

Abstract
Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms of fibroblastic origin that mainly arise from the pleura. Although SFTs arising at numerous extrapleural locations have been reported, extrapleural soft tissue SFTs are extremely rare. The diagnosis of SFTs is based on histologic findings. However, given the histological variability of SFTs, immunohistochemical examination becomes important in their diagnosis. Complete surgical resection is the only and a very important prognostic factor and is recommended for the treatment of both benign and malignant SFTs with a curative intent. Here, the author reports what he believes to be the first case of an SFT originating in the mons pubis.

Abstract
This report describes the first documented case of coexistent mesenteric and gonadal teratomas in an adult female patient. Physical examination of a 51-year-old Korean woman referred for treatment of abdominal distension and pain revealed two masses in both the right upper abdomen and in the right pelvic region. Computed tomography (CT) of the abdomen and pelvis showed the presence of well-defined, complex, fat-dense mass lesions in the upper abdomen and pelvic cavity. A large cystic mass located in the retroperitoneal space extending from the mesenteric border at the level of the transverse colon, and a goose-egg sized right ovarian mass were founded on exploratory laparotomy. The entire abdominal tumor was excised and total hysterectomy with bilateral salpingo-oophorectomy was performed. Examination of the macroscopic and microscopic findings led to diagnosis of mature cystic teratomas of the ovary and the mesentery. The patient's postoperative course was uneventful.

Abstract
PURPOSE The death rate of liver cancer in Korea has been reported as one of the highest in the world. This study was conducted to investigate geographical variations of liver cancer mortality in Korea in order to obtain insight into possible environmental factors related to liver cancer. MATERIALS AND METHODS The sex-specific standardized mortality ratios (SMRs) of liver cancer were calculated for 168 basic administrative units in Korea based upon the vital statistics for the seven years 1992 to 1998, as well as the sex- and age-specific population of each area for 1995. The SMRs were classified into six categories and depicted on a map for each sex. RESULTS The southern provinces showed clearly higher mortality rates as compared to the rest of the country in both males and females. Looking at the maps in detail, there was a geographical variation even within the southern provinces. The areas around large rivers, some costal areas, and costal islands showed a high mortality rate. Even in the middle and northern provinces, the eastern costal areas showed relatively higher mortality rates as compared to inland areas. Conversely, some southern areas known for low levels of pollution showed relatively lower mortality rates. CONCLUSION This finding suggests a possible relationship between liver cancer and water-related foods from polluted rivers or seas. Further studies should be performed in order to clarify which factors cause this geographical variation.

Abstract
PURPOSE To evaluate the efficacy and toxicity of combination chemotherapy with low-dose paclitaxel and cisplatin in patients with advanced non-small cell lung cancer. MATERIALS AND METHODS Chemotherapy-naive patients with unresectable, pathologically proven non-small cell lung cancer were eligible for inclusion in the study. Patients received paclitaxel (145 mg/m2 iv 3 hour D1) and cisplatin (60 mg/m2 iv D1) every 3 weeks. RESULTS Forty-two patients were enrolled between February 2000 and February 2001. The median age was 53.5 years. Patients with adenocarcinoma numbered 29, squamous cell carcinoma 7, large cell carcinoma 3, and undifferentiated carcinoma 3. Seventeen patients had stage IIIB, 19 had stage IV disease and the remaining 6 displayed recurred disease after previous surgical resection. Four patients terminated treatment early because of hypersensitivity (1) and severe emesis (3). Of the 38 evaluable patients, 14 had PR and the response rate was 36.8%. Among partial responders, 6 patients received additional chest radiation. The median duration of response was 47.9 weeks and the median overall survival was 54.0 weeks. Of the total 176 courses, 14 were delayed, 22 required dose reduction, and grade 3~4 neutropenia occurred in 5.6% of courses. Only one episode of neutropenic fever developed and there were no treatment- related mortalities. Other toxicities were generally mild. CONCLUSION The combination chemotherapy with low-dose paclitaxel and cisplatin was effective and tolerable in patients with advanced non-small cell lung cancer.
