A total of 213 fine needle aspirations from pulmonary lesions in 193 patients performed from January, 1986 to March, 1989 were analyzed. The cytologic diagnoses were unsatisfactory in 10, negative in 60, atypical in 6, suspicious in 11 and malignant in 126 cases. The cytologic types of the malignant cases were 47 squamous cell carcinomas, 40 adenocarcinomas, 10 small cell carcinomas, 6 large cell carcinomas and 10 metastatic tumors. They were verified by the histologic confirmation in 31 cases and by the clinical data in the remainder. There were 5 false-negative cases and none was false-positive, representing 96% sensitivity and 100% specificity. Primary lung cancers were accurately typed in 73% of histologically confirmed case. Cell blocks, prepared in 99 cases, were helpful in tumor typing of 11 cases.

2.Chimeric Antigen Receptor-T Cell Therapy
Korean Journal of Medicine 2022;97(4):229-237
Chimeric antigen receptor (CAR) T-cell therapy constitutes a revolutionary advancement in personalized cancer treatment. During this treatment, a patient's own T cells are genetically engineered to express a synthetic receptor that binds a tumor antigen. CAR-T cells are then expanded for clinical use and infused back into the patient's body to attack cancer. CAR-T cells have produced remarkable clinical responses with B-cell malignancies. However, CAR-T cells therapy is not without problems. Barriers to effective CAR-T cells therapy include severe life-threatening toxicities and modest anti-tumor activity. In this review, we introduce the concept of CAR-T cells therapy, currently available CAR-T cells therapy options, and how to deal with adverse events.

PURPOSE: We analyzed the survival and failure patterns of cervix cancer patients treated with irradiation alone to evaluate our treatment method and to compare with the others. METHODS AND MATERIALS: Two hundred and twenty cervical cancer patients, Stage IB, IIA, and IIB who completed the planned treatment between May 1987 and December 1991 were analyzed retrospectively. The Stage IB patients were restaged to the Stage IB1 and IB2 by the recently revised FIGO classification. Patients were treated with a combination of external irradiation and the intracavitary brachytherapy. Determination of the tumor control was done at the time of 6 months postirradiation. The follow-up time was ranged from 3 to 115 months and the mean was 62 months and the follow-up rate was 93.6%(206/220). RESULTS: The overall 5-year survival rate of Stage IB1(N=50), IB2(N=15), IIA(N=58), and IIB(N=97) was 94%, 87%, 69%, and 56%, respectively. In the univariate analysis of prognostic factors,stage(0.00), initial Hg level (p=0.00), initial TA-4(tumor-associated) antigen level(p=0.02), initial CEA level(p=0.02), barrel-shaped tumor(p=0.02), whole cervical involvement (0.00), pelvic lymphadenopathy(LAP) in CT(p=0.04), and post-irradiation adjuvant chemotherapy(p=0.00) were statistically significant in survival analysis. In a while, multivariate analysis showed that the stage was the most powerful prognostic indicator and the post-irradiation chemotherapy factor also showed the statistical significance. The overall local control rate was 81% and by the stage, 100% in Stage IB1, 86.7% in Stage IB2, 84.5% in Stage IIA, and 68.1% in Stage IIB, respectively. The overall tumor recurrence rate was 15.5%(27/174) and by the stage, 8%(4/50) in Stage IB1, 0%(0/13) in Stage IB2, 22.4%(11/49) in Stage IIA, and 19.4%(12/62) in Stage IIB, respectively. CONCLUSIONS: We obtained the similar treatment results to the other's ones in early stage cervical cancer patients. But in Stage IIB, the local control rate was lower than that of the other institutes and also the survival was poorer. So it seems to be necessary to reevaluate the treatment method in advanced cervical cancer patients.

PURPOSE: The adjuvant postoperative radiotherapy has been usually applied to the patients with unfavorable prognostic factors after radical operation in early cervical cancer. We focused on the evaluation of the survival status and failure patterns of the patients with postoperative radiotherapy. MATERIALS AND METHODS: We retrospectively analyzed ninety patients with FIGO stage IB and IIA cervix cancer who received postoperative pelvic irradiation at Chonnam University Hospital between August 1985 and December 1988. Seventy-eight patients had adequate follow-up information for survival anlysis. Median follow-up time of these patients was 64 months. RESULTS: The 5 year overall and disease free survival rate of ninety patients was 80.0% and 80.2% respectively. The prognostic significance to the survival was determined by multivariate analysis. Adequacy of resection margin(p=0.005) and lymph node status(p=0.005) appeared to be independent prognostic factors. Recurrence occurred in 13 Patients, 5 in the pelvis and 8 at distant sites. He median time to recurrence was 19 months(range;3-39 months). The pelvic recurrence was more prevalent in the group of patients with adenocarcinoma, depth of stromal invasion more that 10mm and use of chemotherapy. The distant failure was more prevalent in the group of positive resection margin or positive lymph node with statistical significance. CONCLUSION: Patients with pelvic lymph node or surgical margin involvement clearly constitute a high risk group in this analysis and should be considered as candidates for some form of adjuvant therapy.

PURPOSE: This study was designed to create the job description of Korean transplantation nurse practitioner and examine performance frequencies, criticality, and difficulties of task elements. METHOD: The sample consisted of 63 nurses and coordinators who performed duties related to transplantation at medical center in Korea. A survey method was used, and the questionnaire included frequencies, criticality, and difficulties of task elements in job description by the DACUM method. Using SPSS WIN 10.0, descriptive statistics such as frequency distribution, means, and standard deviations were conducted to examine the subject's general characteristics, the frequencies, criticality, and difficulties of task performance. RESULT: The job description of transplantation nurse practitioners revealed 5 duties, 22 tasks, and 85 task elements. On the all five duties, the averages of the performance frequency, criticality, and difficulty were 2.41, 3.38, and 2.78, meaning that the respondents rarely perform the 5 duties, but consider them critical and easy to perform. CONCLUSION: The job description of the transplantation nurse practitioner included duty, task, and task element and definition of job completed. Thus we recommended a data based trial to confirm and validate the information gathered.

BACKGROUND: High-dose melphalan (HDMEL) represents the standard conditioning regimen before autologous stem cell transplant (ASCT) in multiple myeloma (MM), but recent updates have suggested combination of melphalan with bulsulfan (BUMEL) is also associated with favorable outcomes. We performed the current study to address the lack of comparative studies between the two conditioning regimens in Asian populations. METHODS: Using the Korean National Health Insurance and Korean Health Insurance Review and Assessment Service databases, 1,304 patients newly diagnosed with MM undergoing ASCT between January 2010 and December 2014 were identified. Patients were divided according to conditioning regimen (HDMEL vs. BUMEL), and after case matching, 428 patients undergoing HDMEL conditioning were compared to 107 patients undergoing BUMEL conditioning with respect to clinical course and treatment outcomes. RESULTS: The 3-year progression-free survival (PFS) was 52.5% for the HDMEL conditioning group versus 70.3% for the BUMEL conditioning group (P=0.043). The 3-year overall survival (OS) was 82.0% versus 83.5% (P=0.525), respectively. Although not statistically significant, BUMEL conditioning was associated with more platelet transfusion, while HDMEL was associated with more granulocyte colony stimulating factor support. In multivariate analysis, BUMEL conditioning was not inferior to HDMEL conditioning in regard to both PFS and OS. CONCLUSION: Our study confirmed that BUMEL is an effective and well-tolerated alternative to HDMEL conditioning, with better PFS.
