ABSTRACT

Purpose@#This study aimed to identify the major keywords and the structure of the networks for each major topic to gain knowledge on factors influencing the quality of life of cancer survivors using Text Network Analysis (TNA) and topic modeling. @*Methods@#The study was conducted in four steps:(1) collecting abstracts, (2) text preprocessing in Python, (3) building a co-occurrence matrix, and (4) analyzing network features and clustering topic groups. From 2010 to 2020, 133 studies related to factors affecting the quality of life of cancer survivors were collected from several databases (PubMed, Embase, Cochrane, CINAHL RISS, KoreaMed, KISS). @*Results@#As a result of analyzing 9,968 evaluation results on “breast cancer,” “female,” “depression,” “treatment,” “age,” “questionnaire,” “symptom,” and “diagnosis,” five topics were derived after topic modeling considering coherence score and perplexity score. The main themes were breast cancer survivor, symptom experience, colon cancer survivor, psycho-social factors, and lifestyle and health management. @*Conclusion@#Based on the results of this study, symptoms such as depression, physical activity, and lifestyle and health management are significant factors affecting the quality of life of cancer survivors.

ABSTRACT

Purpose@#We aimed to analyze the treatment outcomes of ipsilateral cervical lymph node (CLN)-positive breast cancer without other distant metastasis and compare the outcomes with those of supraclavicular lymph node (SCL)-positive breast cancer. @*Methods@#Seventy-eight patients with breast cancer and ipsilateral CLN metastasis above the supraclavicular fossa (CLN[+] group) were treated at 7 institutions (2000–2014). Seventy-four patients received systemic chemotherapy and breast surgery followed by locoregional radiotherapy. Outcomes of the CLN(+) group were compared with those of the SCL(+) group, which included 183 patients with SCL involvement. @*Results@#The median follow-up duration was 55.9 months. Twenty-two regional failures were found in 15 patients—axillary lymph node (LN) in 8, SCL in 6, internal mammary LN in 3, previously involved CLN in 4, and previously uninvolved ipsilateral CLN in one patient. The 5-year overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS), and distant metastasis-free survival (DMFS) rates were 68.6%, 46.7%, 68.4%, and 57.0%, respectively. Neck dissection did not improve LRRFS and DFS (p = 0.86 and p = 0.26, respectively). Multivariate analysis showed that hormone receptor negativity and the presence of extracapsular extension were prognostic factors for poor DFS. On comparison with stage IIIC using propensity score matching, survival outcomes of the CLN(+) and SCL(+) groups were not different (5-year OS, p = 0.75; DFS, p = 0.88; LRRFS, p = 0.86; and DMFS, p = 0.45). @*Conclusion@#The comparable clinical outcomes indicate that patients with breast cancer who have ipsilateral CLN metastasis without other distant metastasis may benefit from locoregional treatment of the ipsilateral breast and systemic therapies, as do those with N3c disease.

ABSTRACT

Background/Aims@#We investigated metabolic comorbidity status and patterns of medical institution utilization among breast cancer survivors using medical claims data from the Health Insurance Review and Assessment Service (HIRA). @*Methods@#Using claims data obtained from the HIRA, we selected breast cancer survivors between 2010 and 2015. Descriptive statistics were calculated to determine the frequency of metabolic comorbidities, as well as to analyze patterns of medical institution utilization in accordance with disease status. @*Results@#A total of 89,953 breast cancer survivors were identified. Among these, 12,364 (13.7%) had hypercholesterolemia, 20,754 (23.1%) had hypertension (HTN), and 11,102 (12.3%) had diabetes mellitus (DM). In particular, more than half of breast cancer survivors older than 60 years had HTN, and other diseases sharply increased beginning at age 50 years. For HTN, a total of 531,292 claims were submitted; more than 80% (n = 473,737) were from primary medical institutions, whereas only 2.4% (n = 12,551) were from tertiary medical institutions. The number of claims submitted for DM was 231,526; those from primary medical institutions accounted for 68.5% (n = 158,566), whereas claims from tertiary medical institutions accounted for 12.0% (n = 27,693). In subgroup analyses, the utilization of secondary and tertiary medical institutions was higher among patients with severe diseases and those diagnosed following their breast cancer diagnosis. @*Conclusions@#More than 10% of breast cancer survivors were diagnosed with a metabolic comorbidity. Through analysis of medical institution utilization patterns, we ascertained that a communication system linking secondary and tertiary medical institutions with primary medical institutions is needed.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the treatment outcomes of radiotherapy (RT) for breast cancer with ipsilateral supraclavicular (SCL) and/or internal mammary (IMN) lymph node involvement. MATERIALS AND METHODS: A total of 353 patients from 11 institutions were included. One hundred and thirty-six patients had SCL involvement, 148 had IMN involvement, and 69 had both. All patients received neoadjuvant systemic therapy followed by breast-conserving surgery or mastectomy, and postoperative RT to whole breast/chest wall. As for regional lymph node irradiation, SCL RT was given to 344 patients, and IMN RT to 236 patients. The median RT dose was 50.4 Gy. RESULTS: The median follow-up duration was 61 months (range, 7 to 173 months). In-field progression was present in SCL (n=20) and/or IMN (n=7). The 5-year disease-free survival (DFS) and overall survival rates were 57.8% and 75.1%, respectively. On multivariate analysis, both SCL/IMN involvement, number of axillary lymph node ≥ 4, triple-negative subtype, and mastectomy were significant adverse prognosticators for DFS (p=0.022, p=0.001, p=0.001, and p=0.004, respectively). Regarding the impact of regional nodal irradiation, SCL RT dose ≥ 54 Gy was not associated with DFS (5-year rate, 52.9% vs. 50.9%; p=0.696) in SCL-involved patients, and the receipt of IMN RT was not associated with DFS (5-year rate, 56.1% vs. 78.1%; p=0.099) in IMN-involved patients. CONCLUSION: Neoadjuvant chemotherapy followed by surgery and postoperative RT achieved an acceptable in-field regional control rate in patients with SCL and/or IMN involvement. However, a higher RT dose to SCL or IMN RT was not associated with the improved DFS in these patients.

ABSTRACT

PURPOSE: We compared the oncologic outcomes of breast-conserving surgery plus radiation therapy (BCS+RT) and modified radical mastectomy (MRM) under anthracycline plus taxane-based (AT) regimens and investigated the role of adjuvant radiation therapy (RT) in patients with pathologic N1 (pN1) breast cancer treated by mastectomy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 2,011 patients with pN1 breast cancer who underwent BCS+RT or MRM alone at 12 institutions between January 2006 and December 2010. Two-to-one propensity score matching was performed for balances in variables between the groups. RESULTS: The median follow-up duration for the total cohort was 69 months (range, 1 to 114 months). After propensity score matching, 1,074 patients (676 in the BCS+RT group and 398 in the MRM-alone group) were analyzed finally. The overall survival, disease-free survival, locoregional failure-free survival, and regional failure-free survival (RFFS) curves of the BCS+RT group vs. MRM-alone group were not significantly different. The subgroup analysis revealed that in the group with both lymphovascular invasion (LVI) and histologic grade (HG) III, the BCS+RT showed significantly superior RFFS (p=0.008). Lymphedema (p=0.007) and radiation pneumonitis (p=0.031) occurred more frequently in the BCS+RT group than in the MRM-alone group, significantly. CONCLUSION: There are no differences in oncologic outcomes between BCS+RT and MRM-alone groups under the AT chemotherapy regimens for pN1 breast cancer. However, BCS+RT group showed superior RFFS to MRM-alone group in the patients with LVI and HG III. Adjuvant RT might be considerable for pN1 breast cancer patients with LVI and HG III.

ABSTRACT

This article reviewed new trends and controversial issues, including the intensification of chemotherapy and recent brachytherapy (BT) advances, and also reviewed recent consensuses from different societies on the management of locally advanced cervical cancer (LACC). Intensive chemotherapy during and after radiation therapy (RT) was not recommended as a standard treatment due to severe toxicities reported by several studies. The use of positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) for pelvic RT planning has increased the clinical utilization of intensity-modulated radiation therapy (IMRT) for the evaluation of pelvic lymph node metastasis and pelvic bone marrow. Recent RT techniques for LACC patients mainly aim to minimize toxicities by sparing the normal bladder and rectum tissues and shortening the overall treatment time by administering a simultaneous integrated boost for metastatic pelvic lymph node in pelvic IMRT followed by MRI-based image guided adaptive BT.

ABSTRACT

PURPOSE: The purpose of this study was to examine the effects of integrated psychoeducational program for distress management of newly diagnosed patients with breast cancer. METHODS: A quasi-experimental trial was conducted. The participants consisted of 47 female patients with breast cancer assigned to an intervention group (n=25) and control group (n=22). The intervention group participated in integrated psychoeducational program, consisting of individual face-to-face education and telephone-delivered health-coaching sessions. Data were collected at three time points: pre-intervention (T1), post-intervention (T2), and 6-month follow-up (T3). Study instruments were Distress thermometer, Supportive Care Needs Survey Short Form 34 and Functional Assessment of Cancer Therapy-Breast. RESULTS: Compared with the control group, breast cancer patients in the intervention group reported lower distress and supportive care needs than the control group. The intervention group reported higher quality of life (QOL) overall and higher emotional well-being than the control group. CONCLUSION: These findings indicate that the integrated psychoeducational program is an effective intervention for reducing distress and supportive care needs and increasing QOL of newly diagnosed patients with breast cancer. Oncology nurses need to provide psychoeducational intervention to support patients with breast cancer in managing their distress and helping them adjust to their life.

ABSTRACT

PURPOSE: We aimed to assess prognostic value of metastatic pelvic lymph node (mPLN) in early-stage cervical cancer treated with radical surgery followed by postoperative chemoradiotherapy. Also, we sought to define a high-risk group using prognosticators for recurrence. MATERIALS AND METHODS: A multicenter retrospective study was conducted using the data from 13 Korean institutions from 2000 to 2010. A total of 249 IB-IIA patients with high-risk factors were included. We evaluated distant metastasis-free survival (DMFS) and disease-free survival (DFS) in relation to clinicopathologic factors including pNstage, number of mPLN, lymph node (LN)ratio (number of positive LN/number of harvested LN), and log odds of mPLNs (log(number of positive LN+0.5/number of negative LN+0.5)). RESULTS: In univariate analysis, histology (squamous cell carcinoma [SqCC] vs. others), lymphovascular invasion (LVI), number of mPLNs (≤ 3 vs. > 3), LN ratio (≤ 17% vs. > 17%), and log odds of mPLNs (≤ -0.58 vs. > -0.58) were significant prognosticators for DMFS and DFS. Resection margin involvement only affected DFS. No significant survival difference was observed between pN0 patients and patients with 1-3 mPLNs. Multivariate analysis revealed that mPLN > 3, LVI, and non-SqCC were unfavorable index for both DMFS (p 3 in early-stage cervical cancer affects DMFS and DFS. A scoring system using mPLNs > 3, LVI, and non-SqCC could stratify risk groups of recurrence in surgically resected early-stage cervix cancer with high-risk factors.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the impact of postmastectomy radiotherapy (PMRT) on loco-regional recurrence-free survival (LRRFS), disease-free survival (DFS), and overall survival (OS) in pT1-2N1 patients treated with taxane-based chemotherapy. MATERIALS AND METHODS: We retrospectively reviewed the medical data of pathological N1 patients who were treated with modified radical mastectomy and adjuvant taxane-based chemotherapy in 12 hospitals between January 2006 and December 2010. RESULTS: We identified 714 consecutive patients. The median follow-up duration was 69 months (range, 1 to 114 months) and the 5-year LRRFS, DFS, and OS rates were 97%, 94%, and 98%, respectively, in patients who received PMRT (PMRT [+]). The corresponding figures were 96%, 90%, and 96%, respectively, in patients who did not receive PMRT (PMRT [–]). PMRT had no significant impact on survival. Upon multivariable analysis, only the histological grade (HG) was statistically significant as a prognostic factor for LRRFS and DFS. In a subgroup analysis of HG 3 patients, PMRT (+) showed better DFS (p=0.081). CONCLUSION: PMRT had no significant impact on LRRFS, DFS, or OS in pT1-2N1 patients treated with taxane-based chemotherapy. PMRT showed a marginal benefit for DFS in HG 3 patients. Randomized studies are needed to confirm the benefit of PMRT in high risk patients, such as those with HG 3.

ABSTRACT

PURPOSE: This study was conducted to evaluate the impact of supraclavicular lymph node radiotherapy (SCNRT) on N1 breast cancer patients receiving post-lumpectomy whole-breast irradiation (WBI) and anthracycline plus taxane-based (AT) chemotherapy. MATERIALS AND METHODS: We performed a case-control analysis to compare the outcomes of WBI and WBI plus SCNRT (WBI+SCNRT). Among 1,147 patients with N1 breast cancer who received post-lumpectomy radiotherapy and AT-based chemotherapy in 12 hospitals, 542 were selected after propensity score matching. Patterns of failure, disease-free survival (DFS), distant metastasis-free survival (DMFS), and treatment-related toxicity were compared between groups. RESULTS: A total of 41 patients (7.6%) were found to have recurrence. Supraclavicular lymph node (SCN) failure was detected in three patients, two in WBI and one in WBI+SCNRT. All SCN failures were found simultaneously with distant metastasis. There was no significant difference in patterns of failure or survival between groups. The 5-year DFS and DMFS for patients with WBI and WBI+SCNRT were 94.4% versus 92.6% (p=0.50) and 95.1% versus 94.5% (p=0.99), respectively. The rates of lymphedema and radiation pneumonitis were significantly higher in the WBI+SCNRT than in the WBI. CONCLUSION: We did not find a benefit of SCNRT for N1 breast cancer patients receiving AT-based chemotherapy.

ABSTRACT

PURPOSE: Psychological distress is a significant and ongoing problem for breast cancer. These mental health problems are often neglected as they are not always properly understood. This study was performed to explore the trajectory of psychological distress over 1 year since breast cancer surgery and to identify the associated factors for the trajectory. METHODS: One hundred seventeen women who underwent surgery for breast cancer completed the psychological distress thermometer and problem lists from after surgery to 12 months after surgery. Information on their sociodemographic and clinical characteristics was also obtained. Group-based trajectory modeling was performed to identify the distinct trajectories of psychological distress. Chisquare test and logistic regression analysis were performed to determine predictors of psychological distress trajectories. RESULTS: two-group linear trajectory model was optimal for modeling psychological distress (Bayesian information criterion = −777.41). Group-based trajectory modeling identified consistently high-distress (19.4%) and low-decreasing distress (80.6%) trajectories. Old age, depression, nervousness, and pain were significant predictors of consistently high-distress trajectory. CONCLUSION: Our results indicate that distinct trajectory groups can be used as a screening tool to identify patients who may be at an increased risk of psychological distress over time. Screening for psychological distress during disease diagnosis is important and necessary to identify patients who are at an increased risk of elevated distress or at risk of experiencing psychological distress over time.

ABSTRACT

PURPOSE: The effects of biological subtypes within breast cancer on prognosis are influenced by age at diagnosis. We investigated the association of young age with locoregional recurrence (LRR) between patients with luminal subtypes versus those with nonluminal subtypes. MATERIALS AND METHODS: Medical records of 524 breast cancer patients with positive lymph nodes between 1999 and 2010 were reviewed retrospectively. All patients received curative surgery and adjuvant chemotherapy based on contemporary guidelines. Radiation was delivered for patients who underwent breast conserving surgery or those who had four or more positive lymph nodes after mastectomy. Adjuvant hormone therapy was administered to 413 patients with positive hormone receptors according to their menstrual status. RESULTS: During median follow-up of 84 months, the 10-year locoregional recurrence-free survival rate (LRRFS) was 84.3% for all patients. Patients < 40 years showed significantly worse 10-year LRRFS than those ≥ 40 years (73.2% vs. 89.0%, respectively; p=0.01). The negative effect of young age on LRRFS was only observed in luminal subtypes (69.7% for < 40 years vs. 90.8% for ≥ 40 years; p < 0.01). Multivariate analysis using luminal subtypes ≥ 40 years as a reference revealed luminal subtypes < 40 years were significantly associated with increased risk of LRR (hazard ratio, 2.33; p < 0.01). CONCLUSION: Young breast cancer patients with positive lymph nodes had a higher risk of LRR than those aged ≥ 40 years. This detrimental effect of young age on LRR was confined in luminal subtypes.

ABSTRACT

PURPOSE: The objective of this study was to explore the relationship between the circulating lymphocyte level during preoperative chemoradiotherapy (CRT) and pathologic complete response (pCR) in locally advanced rectal cancer. MATERIALS AND METHODS: From May 2010 to May 2013, 52 patients treated with preoperative CRT followed by surgery, were analysed. Patients received conventional fractionated radiotherapy (50-54 Gy) with fluorouracil-based chemotherapy. Surgical resection was performed at 4 to 8 weeks after the completion of preoperative CRT. Absolute blood lymphocyte counts and their relative percentage in total white blood cell counts were obtained from complete blood count tests performed prior to and after 4, 8, and 12 weeks of CRT. We analysed the association between achieving pCR and change in blood lymphocyte level during CRT, as well as clinical parameters. RESULTS: Among 52 patients, 14 (26.9%) had evidence of pCR. Sustaining the blood lymphocyte count during CRT (lymphocyte count at 4 weeks/baseline lymphocyte count > 0.35; odds ratio, 8.33; p=0.02) and initial carcinoembryonic antigen < 4.4 ng/mL (odds ratio, 6.71; p=0.03) were significantly associated with pCR in multivariate analyses. CONCLUSION: Sustaining blood lymphocyte count during preoperative CRT was predictive for pCR in rectal cancer. Further studies are warranted to investigate the association between pathologic responses and circulating lymphocyte count with its subpopulation during preoperative CRT.

ABSTRACT

Radiation therapy is an effective modality to alleviate cancer-related symptoms. To deliver radiation accurately, it is essential to secure stability of the treatment position in patients during each treatment time. However, some patients could be less cooperative due to their psychoemotional issues. We present two cases of terminal-stage cancer patients who were initially unable to lie still on the treatment table before simulation. A relaxation technique was taught to them on the bed, and they could relax and undergo radiation therapy with effective symptom relief.

ABSTRACT

PURPOSE: Our institution has implemented two different adjuvant protocols in treating patients with non-small cell lung cancer (NSCLC): chemotherapy followed by concurrent chemoradiotherapy (CT-CCRT) and sequential postoperative radiotherapy (PORT) followed by postoperative chemotherapy (POCT). We aimed to compare the clinical outcomes between the two adjuvant protocols. MATERIALS AND METHODS: From March 1997 to October 2012, 68 patients were treated with CT-CCRT (n = 25) and sequential PORT followed by POCT (RT-CT; n = 43). The CT-CCRT protocol consisted of 2 cycles of cisplatin-based POCT followed by PORT concurrently with 2 cycles of POCT. The RT-CT protocol consisted of PORT followed by 4 cycles of cisplatin-based POCT. PORT was administered using conventional fractionation with a dose of 50.4–60 Gy. We compared the outcomes between the two adjuvant protocols and analyzed the clinical factors affecting survivals. RESULTS: Median follow-up time was 43.9 months (range, 3.2 to 74.0 months), and the 5-year overall survival (OS), locoregional recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were 53.9%, 68.2%, and 51.0%, respectively. There were no significant differences in OS (p = 0.074), LRFS (p = 0.094), and DMFS (p = 0.490) between the two protocols. In multivariable analyses, adjuvant protocol remained as a significant prognostic factor for LRFS, favouring CT-CCRT (hazard ratio [HR] = 3.506, p = 0.046) over RT-CT, not for OS (HR = 0.647, p = 0.229). CONCLUSION: CT-CCRT protocol increased LRFS more than RT-CT protocol in patients with completely resected NSCLC, but not in OS. Further studies are warranted to evaluate the benefit of CCRT strategy compared with sequential strategy.

ABSTRACT

PURPOSE: The objective of this prospective study was to evaluate the relationship between the circulating lymphocyte subpopulation counts during preoperative chemoradiotherapy (CRT) and tumor response in locally advanced rectal cancer. MATERIALS AND METHODS: From August 2015 to June 2016, 10 patients treated with preoperative CRT followed by surgery were enrolled. Patients received conventional fractionated radiotherapy (50.4 Gy) with fluorouracil-based chemotherapy. Surgical resection was performed at 4 to 8 weeks after the completion of preoperative CRT. The absolute blood lymphocyte subpopulation was obtained prior to and after 4 weeks of CRT. We analyzed the association between a tumor response and change in the lymphocyte subpopulation during CRT. RESULTS: Among 10 patients, 2 (20%) had evidence of pathologic complete response. In 8 patients with clinically node positive, 4 (50%) had nodal tumor response. All lymphocyte subpopulation counts at 4 weeks after CRT were significantly lower than those observed during pretreatment (p < 0.01). A high decrease in natural killer (NK) cell, count during CRT (baseline cell count − cell count at 4 weeks) was associated with node down staging (p = 0.034). CONCLUSION: Our results suggest that the change of lymphocyte subset to preoperative CRT may be a predictive factor for tumor response in rectal cancer.

ABSTRACT

PURPOSE: The purpose of this study was to identify changes of supportive care needs and relationship to quality of life (QOL) in patients with breast cancer. METHODS: 117 patients with breast cancer were administered the Supportive Care Needs Survey-Short form 34 and the Functional Assessment of Cancer Therapy-Breast before adjuvant therapy after mastectomy (T1), at the end of completing adjuvant therapy (T2), as well as 6 months after the completion of adjuvant therapy (T3). Data were analyzed using SPSS/Win 21.0. RESULTS: The highest unmet supportive care needs were observed in the health system and information domain and the psychological domain at each time point. The health system and information (F=22.49, p<.001) and physical and daily living needs (F=5.72, p=.004) were higher at T1 and T2 than T3. The psychological (F=7.43, p=.001) and patient care and support needs were higher at T1 than T2 and T3. Multiple regression analysis showed that breast cancer patients with greater physical and daily living and psychological needs were significantly associated with poorer QOL at all times. CONCLUSION: Supportive care should be timely provided to breast cancer patients to improve their ability to cope with physical and psychological problem and QOL. Breast cancer patients who had more unmet needs in psychological and physical domains were more likely to have a poor QOL.

ABSTRACT

PURPOSE: We evaluated the role of adjuvant therapy in stage IIIA endometrioid adenocarcinoma patients who underwent surgery followed by radiotherapy (RT) alone or chemoradiotherapy (CTRT) according to risk group. MATERIALS AND METHODS: A multicenter retrospective study was conducted including patients with surgical stage IIIA endometrial cancertreated by radical surgery and adjuvant RT or CTRT. Disease-free survival (DFS) and overall survival (OS) were analyzed. RESULTS: Ninety-three patients with stage IIIA disease were identified. Nineteen patients (20.4%) experienced recurrence, mostly distant metastasis (17.2%). Combined CTRT did not affect DFS (74.1% vs. 82.4%, p=0.130) or OS (96.3% vs. 91.9%, p=0.262) in stage IIIA disease compared with RT alone. Patients with age ≥ 60 years, grade G2/3, and lymphovascular space involvement had a significantly worse DFS and those variables were defined as risk factors. The high-risk group showed a significant reduction in 5-year DFS (≥ 2 risk factors) (49.0% vs. 88.0%, p < 0.001) compared with the low-risk group (< 2). Multivariate analysis confirmed that more than one risk factor was the only predictor of worse DFS (hazard ratio, 5.45; 95% confidence interval, 2.12 to 13.98; p < 0.001). Of patients with no risk factors, a subset treated with RT alone showed an excellent 5-year DFS and OS (93.8% and 100%, respectively). CONCLUSION: We identified a low-risk subset of stage IIIA endometrioid adenocarcinoma patients who might be reasonable candidates for adjuvant RT alone. Further randomized studies are needed to determine which subset might benefit from combined CTRT.

ABSTRACT

OBJECTIVE: The purpose of this study is to validate the Gynecologic Oncology Group (GOG) criteria for adjuvant treatment in a different cohort of patients and to evaluate the simplified risk criteria predicting the prognosis and tailoring adjuvant treatment in patients with surgically staged endometrial cancer. METHODS: We performed a retrospective analysis of 261 consecutive patients with surgically staged endometrial cancer between January 2000 and February 2013. All patients had complete staging procedures and were surgically staged according to the 2009 International Federation of Gynecology and Obstetrics staging system. Clinical and pathologic data were obtained from medical records. We designed the simplified risk criteria for adjuvant treatment according to the risk factors associated with survival. The patients were divided into low and low-intermediate, high-intermediate, and high-risk groups according to the GOG criteria and simplified criteria and their survivals were compared. Receiver-operating characteristic curve analysis was used to evaluate the prognostic significance of both criteria. RESULTS: Median follow-up time was 48 months (range, 10 to 122 months). According to the GOG criteria, we identified 197 low and low-intermediate risk patients, 20 high-intermediate risk patients, and 44 high-risk patients. There were significant differences in disease-free (p<0.001) and overall survival (p<0.001) among the three groups. Using the simplified risk criteria, we identified 189 low and low-intermediate risk patients, 28 high-intermediate risk patients, and 44 high-risk patients. There were significant differences in disease-free (p<0.001) and overall survival (p<0.001) among the three groups. The performance of the simplified criteria (area under the curve [AUC]=0.829 and 0.916 for disease recurrences and deaths, respectively) was as good as the GOG criteria (AUC=0.836 and 0.921 for disease recurrences and deaths, respectively). CONCLUSION: The simplified criteria may be easily applicable and offer useful information for planning strategy of adjuvant treatment in patients with surgically staged endometrial cancer as the GOG criteria.

ABSTRACT

PURPOSE: The purpose of this study was to determine the prevalence of distress and to investigate the related problems in breast cancer patients at the end of primary treatment. METHODS: A sample of 118 participants was recruited among outpatients who had successfully completed primary treatment of breast cancer. Data were collected between July, 2013 and October, 2014 using the Distress Thermometer (DT) scale and problem lists. Descriptive statistics and logistic regression analysis were used to analyze data. RESULTS: Among the 118 patients that participated in this study, 34 patients (28.8%) suffered from elevated distress using the previously validated cut point > or =4 for the DT. Problems most frequently encountered were fatigue (68.8%), worry (59.3%), appearance (51.7%) and memory/concentration (48.3%). Multivariate logistic regression analysis revealed that depression (OR=9.55), worry (OR=8.34), fatigue (OR=8.19) and age (OR=1.14) were independent predictors for elevated distress scores. CONCLUSION: Utilizing the DT, onethird of breast cancer patients screened met criteria for distress at the end of the primary treatment. Breast cancer patients with depression, worry, fatigue and older age should be targeted for distress screening and management.
