Purpose
The purpose of the study was to validate the Korean version of Cancer Survivors’ Unmet Needs (CaSUN) scale among non–small cell lung cancer survivors.
Materials and Methods
Participants were recruited from outpatient clinics at the Samsung Medical Center in Seoul, South Korea, from January to October 2020. Participants completed a survey questionnaire that included the CaSUN. Exploratory and confirmatory factor analysis and Pearson’s correlations were used to evaluate the reliability and validity of the Korean version of the CaSUN (CaSUN-K). We also tested known-group validity using an independent t test or ANOVA.
Results
In total, 949 provided informed consent and all of which completed the questionnaire. Among the 949 patients, 529 (55.7%) were male; the mean age and median time since the end of active treatment (standard deviation) was 63.4±8.8 years and the median was 18 months. Although the factor loadings were different from those for the original scale, the Cronbach’s alpha coefficients of the six domains in the CaSUN-K ranged from 0.68 to 0.95, indicating satisfactory internal consistency. In the CFA, the goodness-of-fit indices for the CaSUN-K were high. Moderate correlations demonstrated the convergent validity of CaSUN-K with the relevant questionnaire. More than 60% of the participants reported information-related unmet needs, and the CaSUN-K discriminated between the needs reported by the different subgroups that we analyzed.
Conclusion
The CaSUN-K is a reliable and valid measure for assessing the unmet needs in a cancer population, thus this tool help population to receive timely, targeted, and relevant care.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
Purpose
This multi-center, retrospective study was conducted to evaluate the long-term survival in patients who underwent surgical resection for small cell lung cancer (SCLC) and to identify the benefit of adjuvant therapy following surgery.
Materials and Methods
The data of 213 patients who underwent surgical resection for SCLC at four institutions were retrospectively reviewed. Patients who received neoadjuvant therapy or an incomplete resection were excluded.
Results
The mean patient age was 65.29±8.93 years, and 184 patients (86.4%) were male. Lobectomies and pneumonectomies were performed in 173 patients (81.2%), and 198 (93%) underwent systematic mediastinal lymph node dissections. Overall, 170 patients (79.8%) underwent adjuvant chemotherapy, 42 (19.7%) underwent radiotherapy to the mediastinum, and 23 (10.8%) underwent prophylactic cranial irradiation. The median follow-up period was 31.08 months (interquartile range, 13.79 to 64.52 months). The 5-year overall survival (OS) and disease-free survival were 53.4% and 46.9%, respectively. The 5-year OS significantly improved after adjuvant chemotherapy in all patients (57.4% vs. 40.3%, p=0.007), and the survival benefit of adjuvant chemotherapy was significant in patients with negative node pathology (70.8% vs. 39.7%, p=0.004). Adjuvant radiotherapy did not affect the 5-year OS (54.6% vs. 48.5%, p=0.458). Age (hazard ratio [HR], 1.032; p=0.017), node metastasis (HR, 2.190; p < 0.001), and adjuvant chemotherapy (HR, 0.558; p=0.019) were associated with OS.
Conclusion
Adjuvant chemotherapy after surgical resection in patients with SCLC improved the OS, though adjuvant radiotherapy to the mediastinum did not improve the survival or decrease the locoregional recurrence rate.

AbstractAbstract PDFPubReaderePub
Purpose
Survival probability changes over time in cancer survivors. This study examined conditional survival in patients undergoing curative resection for non-small cell lung cancer (NSCLC).
Materials and Methods
Five-year conditional recurrence-free survival (CRFS), conditional overall survival (COS), and conditional relative survival (CRS) up to 10 years after surgery were calculated in patients who underwent NSCLC resection from 1994 to 2016. These rates were stratified according to age, sex, year of diagnosis, pathological stage, tumor histology, smoking status, comorbidity, and lung function.
Results
Five-year CRFS increased from 65.6% at baseline to 90.9% at 10 years after surgery. Early differences in 5-year CRFS according to stratified patient characteristics disappeared, except for age: older patients exhibited persistently lower 5-year CRFS. Five-year COS increased from 72.7% to 78.3% at 8 years and then decreased to 75.4% at 10 years. Five-year CRS increased from 79.0% at baseline to 86.8% at 10 years. Older age and higher pathologic stage were associated with lower 5-year COS and CRS up to 10 years after surgery. Female patients, those with adenocarcinoma histology, non-smokers, patient without comorbidities and had good lung function showed higher COS and CRS.
Conclusion
CRFS improved over time, but significant risk remained after 5 years. CRS slightly improved over time but did not reach 90%, suggesting significant excess mortality compared to the general population. Age and stage remained significant predictors of conditional survival several years after surgery. Our conditional survival estimates should help clinicians and patients make informed treatment and personal life decisions based on survivorship status.

AbstractAbstract PDFPubReaderePub
Purpose
The optimal adjuvant therapy modality for treating pN2 non-small cell lung cancer patients has not yet been established. In this study, the authors investigated clinical outcomes following three different adjuvant therapy modalities.
Materials and Methods
From January 2006 to December 2012, 240 patients with cN0/1 disease were found to have pN2 disease following curative resection and received one of three adjuvant therapy modalities:thoracic radiation therapy (TRT) and concurrent chemotherapy (CTx) (CCRT) (group I), CCRT plus consolidation CTx (group II), and CTx alone (group III). TRT was delivered to 155 patients (groups I/II), and full dose CTxwas delivered to 172 patients either as a consolidative or a sole modality (group II/III).
Results
During 30 months of median follow-up, 44 patients died and 141 developed recurrence. The 5-year overall survival (OS), locoregional control (LRC), distant metastasis-free survival (DMFS), and disease-free survival (DFS) rates of all patients were 76.2%, 80.7%, 36.4%, and 29.6%, respectively. There was no difference in OS among groups. TRT (groups I/II) significantly improved LRC, full dose CTx (groups II/III) did DMFS, and CCRT plus consolidation CTx (group II) did DFS, respectively.
Conclusion
The current study could support that TRT could improve LRC and full dose CTx could improve DMFS and that CCRT plus consolidation CTx could improve DFS.

AbstractAbstract PDFSupplementary MaterialPubReaderePub
Purpose
The optimal perioperative treatment for resectable esophageal squamous cell carcinoma (ESCC) remains controversial. We evaluated the efficacy and safety of leucovorin and 5-fluorouracil (LV5FU2) and LV5FU2 plus oxaliplatin (FOLFOX) combination chemotherapies administered adjuvantly for curatively-resected, node-positive ESCC.
Materials and Methods
Patients with pathologically node-positive esophageal cancer after curative R0 resection were enrolled and randomly assigned to receive LV5FU2 or FOLFOX biweekly for up to eight cycles. The primary endpoint was disease-free survival (DFS).
Results
Between 2011 and 2015, 62 patients were randomized into the two treatment groups (32 in the LV5FU2 arm and 30 in the FOLFOX arm). The median age was 60 years and both groups had similar pathologic characteristics in tumor, nodal status, and location. Treatment completion rates were similarly high in both groups. The DFS rate at 12 months was 67% in the LV5FU2 group and 63% in the FOLFOX group with a hazard ratio of 1.3 (95% confidence interval [CI], 0.66 to 2.62). After a median follow-up period of 27 months, the median DFS was 29.6 months (95% CI, 4.9 to 54.2) in the LV5FU2 arm and 16.8 months (95% CI, 7.5 to 26.1) in the FOLFOX arm (p=0.428), respectively, while the median overall survival was not reached in either arm. Grade 3 or 4 neutropenia was more frequent in patients in the FOLFOX arm than the LV5FU2 arm (20.0% vs. 3.1%).
Conclusion
The addition of oxaliplatin (FOLFOX) did not lead to better efficacy compared to LV5FU2 chemotherapy in an adjuvant setting in node-positive ESCC patients.

Purpose

We evaluated clinical outcomes after drainage for malignant pericardial effusion with imminent or overt tamponade.

Materials and Methods

Between August 2001 and June 2007, 100 patients underwent pericardiocentesis for malignant pericardial effusion. Adequate follow-up information on the recurrence of pericardial effusion and survival status was available for 98 patients.

Results

Recurrence of effusion occurred in 30 patients (31%), all of whom were diagnosed with adenocarcinoma. Multivariate analysis indicated that adenocarcinoma of the lung (hazard ratio [HR], 6.6; 95% confidence interval [CI], 1.9 to 22.3; p=0.003) and progressive disease despite chemotherapy (HR, 4.3; 95% CI, 1.6 to 12.0; p=0.005) were independent predictors of recurrence. Survival rates three months after pericardiocentesis differed significantly with the type of primary cancer; the rates were 73%, 18%, 90% and 30% in patients with adenocarcinoma of the lung, squamous cell carcinoma of the lung, breast cancer and other cancers, respectively.

Conclusion

Recurrence and survival of patients with malignant pericardial effusion are dependent on the type of primary cancer and response to chemotherapy. Patients with adenocarcinoma of the lung may be good candidates for surgical drainage to avoid repeated pericardiocentesis, but pericardiocentesis is considered effective as palliative management in patients with other cancers.

Cancer Res Treat. 2003;35(3):232-238.   Published online June 30, 2003

AbstractAbstract PDF
PURPOSE
Mediastinal staging of non-small cell lung cancer can be markedly improved by FDG-PET scan, but the problem of false staging of mediastinal nodes by PET scan in non-small cell lung cancer has not yet been overcome. The aim of this study was to identify the mechanism underlying the false staging of mediastinal nodes by FDG-PET in the case of non-small cell lung cancer. MATERIALS AND METHODS: To evaluate the factors determining the FDG uptake in mediastinal nodes, FDG-PET was performed preoperatively, and mediastinal dissection with pulmonary resection was performed in 62 patients with NSCLC. GLUT-1 expression was studied by immunohistochemistry of the mediastinal nodes (n=111, true positive 31, true negative 41, false positive 27, false negative 12) using the anti-GLUT-1 antibody. The size, percentage of tumor (tumor ratio), labeling index (rate of stained tumor), staining intensity of the tumor, level of follicular hyperplasia, and staining intensity of the follicle center in the mediastinal node were also studied. RESULTS: There was no significant difference in size among the 4 nodal groups (TP, TN, FP, FN), nor in the tumor ratio of the metastatic nodes between the TP and FN groups. The labeling index and staining intensity of the TP group were higher than those of the FN group (Mann-Whitney test, p=.001, p=.007) in the case of the metastatic nodes. The level of follicular hyperplasia of the FP group was higher than that of the TN group in the case of the non-metastatic nodes (p=.000). CONCLUSION: These results suggest that in mediastinal staging of non-small cell lung cancer by FDG-PET, the FN node is associated with low uptake of FDG due to low expression of GLUT-1, and that the FP node is associated with a high level of follicular hyperplasia as a result of there being a reactive change to an inflammatory and/or immune reaction. This is the first report on the mechanism underlying the false results that are sometimes obtained, and which constitute a major problem in the clinical application of FDG-PET to the mediastinal staging of non-small cell lung cancer.

AbstractAbstract PDF
PURPOSE
Multicentric occurrence of esophageal squamous neoplasm has been known to be significant in terms of its pathogenesis and production of detectable early lesions. This study was performed to establish the incidence, pattem and clinico-pathologic features of multiple squamous epithelial neoplasia of the esophagus in Korea.
MATERIALS AND METHODS
Forty-two consecutive cases of esophageal squamous cell carcinoma surgically treated at Korea Cancer Center Hospital in 1991 were studied. For pathological analysis, whole esophagectomy specimens were sectioned, micrascopically examined, and reconstructed. Age, sex, alcohol and smoking history, tumor location, stage, lymph node metastasis and survival were compared among different neoplastic conditions.
RESULT
Fifteen cases (35.7%) showed multiple squamous lesions, 6 (14.3%) with multiple carcinomas and dysplasias, and 9 (21.4%) with single carcinomas with separate dysplasias. Intraepithelial lesions contiguous to main tumors were commonly observed (61.9%). Lugol`s solution staining pattern was compatible with epithelial pathology. Lymph node metastasis rate was significantly higher in cases with multiple carcinomas. Smoking history was significantly more common in patients with solitary catcinomas only.
CONCLUSION
The multicentric occurrence of squamous epithelial dysplasia and carcinoma in the esophagus was confirmed in Korean patients, supporting the concept of field carcinogenesis at this region. However, lack of evidence for strong environmental influence in the patients with multiple lesions suggests yet another risk factor.

J Korean Cancer Assoc. 1995;27(5):816-822.
AbstractAbstract PDF
The clinical staging of lung cancer, especially stage IIIA, provides important information for clinical analysis and treatment method to surgeon ar radiation oncologist. The aim of this analysis is to evaluate of difference between clinical staging and pathologic staging and determine to accuracy of preoperative pathologic diagnosis and clinical staging for clinically staged IIIA NSCLC. Analysis was performed on 138 patients who has been staged IIIA NSCLC. Pathologic diagnosis was performed using sputum cytology, bronchoscopy or percutaneous needle aspiration. All patients were evaluated by CT and staged according to American Joint Commit- tee on Cancer staging classification. All patients received the thoracotomy. The pathologic diagnosis was changed after surgery in 9 patients(6.5%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CT in dis- tinguishing T3 from Tl-T2 were 62.5%, 89.7%, 47.6%, 87.5%, and 75.3%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CT in distinguishing N2 from NO-Nl were 91.8%, 24.3%, 42.7%, 78.3%, and 54.8% respec- tively. According to pathologic staging, there were 27(19.6%) patients in stage I, 24(17.4%) in stage II, 64(46.4%) in stage IIIA, 21(15.2%) in stage IIIB, and 2(1.5%) in stage IV. Comparing clincal staging with pathologic staging, concordant results were found in 46.4%, 37.0% were clinically overestimated and 16.7% underestimated. Preoperative pathologic diagnosis was well correlate postoperative pathologic finding. But CT accuracy was low in both primary tumor and mediastinal lymph node. Especially to diagnose malignant involvement of mediastinal nodes, CT is not a valid means. Patients would not be denied the opportunity for curative surgery on the basis of CT signs.

AbstractAbstract PDF
Neoadjuvant chemotherpay of esophageal cancers is recently considered to be beneficial to downstaging of tumors. This study was aimed ta describe morphologic alterations and expression of P-glycoprotein in esophageal cancers after chemotherapy and discuse their clinical sig- nificances. Eleven cases of esophageal cancers which were surgicelly resected l-5 cycles of chemotherapy with C-DDP/VP-16/5-FU(PEF)or C-DDP/5-FU(FP) were reviewed. On microscopic examination, all of ll cases(100%) revealed no major pathologic alterations. Only five cases(45%) showed non-specific partial pathologic responses, histologically observing foreign body reaction, calcification, necrosis, desmoplasia, vascular dilatation, and nuclear anaplasia. The changes were also observed in metastatic tumors in regional lymph nodes. The presence of non-specific pathologic responses and downstaging of tumors did not correlate each other. Immunohistochemically, all of the cases were negative for P-glycoprotein. Our data suggest that PEF or FP neoadjuvant chemotherpay for esophageal cancers is ineffecitive.

Mutation of K - ras Oncogene in Non - Small Cell lung Cancer
Choon Taek Lee, Keun Chil Park, Chang Min Kim, Jae Ill Zo, Young Mog Shim, Weon Seon Hong, Jhin Oh Lee, Taik Koo Yun
J Korean Cancer Assoc. 1994;26(1):100-106.
AbstractAbstract PDF
The mutations of K-ras oncogenes have been detected in about 20~30% of non-small cell lung cancer(NSCLC). In some reports K-ras activations are associated with smoking and poor prognosis in NSCLC patients who undergo curative resection. The ras oncogenes are usually activated by point mutations. The development of polymerase chain reaction-single strand conformation polymorphism(PCR-SSCP) enables us to detect the subtle nucleotide changes such as point mutations. In SSCP the electrophoretic mobility of single strand nucleotide de- pends on not only its size but also its conformation determined by DNA sequences. We analysed genomic DNAs of 41 human NSCLC obtained by thoracotomy using PCR-SSCP of K- ras codon 12, 13 and K-ras codon 61, and compared the results with clinical informations. The electrophoretic mobility changes were found in 10 of 41 NSCLCs(24.4%) in K-ras codon 12, 13. Those changes were found in six of 25 squamous cell carcinomas(24% ) and four of 16 adenocarcinomas(25%). But no change was found in K-ras codon 61. Comparisans of clinical parameters including age, sex, stage, smoking, and survival showedno significant differences between two groups with or without K-ras mutation. These results suggest that the mutation of K-ras oncogene may play an important role in the pathogenesis of some group of NSCLC though the clinical significances of these molecular events are open to further investigations.
