Background:
Anastomotic leakage (AL) following esophagectomy represents a serious complication that often results in prolonged hospitalization and necessitates repeated interventions, including nothing-by-mouth (NPO) restriction, endoscopic vacuum therapy (EVT), or surgical repair. In this study, we evaluated the patterns and outcomes of AL treatment.
Methods:
We retrospectively reviewed the medical records of patients who underwent esophagectomy for esophageal cancer at a single center between 2003 and 2020. Of 3,096 examined cases, 181 patients (5.8%) with AL were included in the study: 114 patients (63%) with cervical anastomosis (CA) and 67 (37%) with intrathoracic anastomosis (TA).
Results:
The incidence of AL was 11.9% in the CA and 3.2% in the TA group (p<0.001).Among patients with CA who developed AL, 87 (76.3%) were managed with NPO, 15 (13.2%) with EVT, and 12 (10.5%) with surgical repair. Over 90% of patients with cervical AL resumed an oral diet by the time of discharge, regardless of treatment method. Among patients with TA and AL, 36 (53.7%) received NPO, 25 (37.7%) underwent EVT, and 6 (9%) required surgery. Of these, 34 patients who were managed with NPO and 19 with EVT could resume an oral diet. However, only 2 patients who underwent surgery resumed an oral diet, and 2 patients required additional EVT.
Conclusion
Although patients with CA displayed a higher incidence of AL, their rate of successful oral intake exceeded that of those with TA, regardless of treatment method.Among patients exhibiting AL with TA, EVT was more commonly employed than in CA cases, and it appears effective.

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.

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.

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.

BACKGROUND:
Primary chest wall sarcoma is a rare disease with limited reports of surgical resection.
METHODS:
This retrospective review included 41 patients with primary chest wall sarcoma who underwent chest wall resection and reconstruction from 2001 to 2015. The clinical, histologic, and surgical variables were collected and analyzed by univariate and multivariate Cox regression analyses for overall survival (OS) and recurrence-free survival (RFS).
RESULTS:
The OS rates at 5 and 10 years were 73% and 61%, respectively. The RFS rate at 10 years was 57.1%. Multivariate Cox regression analysis revealed old age (hazard ratio [HR], 5.16; 95% confidence interval [CI], 1.71–15.48) as a significant risk factor for death. A surgical resection margin distance of less than 1.5 cm (HR, 15.759; 95% CI, 1.78–139.46) and histologic grade III (HR, 28.36; 95% CI, 2.76–290.87) were independent risk factors for recurrence.
CONCLUSION
Long-term OS and RFS after the surgical resection of primary chest wall sarcoma were clinically acceptable.

BACKGROUND: A method of wound closure using knotless suture material in the chest tube site has been introduced at our center, and is now widely used as the primary method of closing chest tube wounds in video- assisted thoracic surgery (VATS) because it provides cosmetic benefits and causes less pain. METHODS: We included 109 patients who underwent VATS pulmonary resection at Samsung Medical Center from October 1 to October 31, 2016. Eighty-five patients underwent VATS pulmonary resection with chest drain wound closure utilizing knotless suture material, and 24 patients underwent VATS pulmonary resection with chest drain wound closure by the conventional method. Complications related to the chest drain wound were compared between the 2 groups. RESULTS: There were 2 cases of pneumothorax after chest tube removal in both groups (8.3% in the conventional group, 2.3% in the knotless suture group; p=0.172) and there was 1 case of wound discharge due to wound dehiscence in the knotless suture group (0% in the conventional group, 1.2% in the knotless suture group; p=0.453). There was no reported case of chest tube dislodgement in either group. The complication rates were non-significantly different between the 2 groups. CONCLUSION: The results for the complication rates of this new chest drain wound closure method suggest that this method is not inferior to the conventional method. Chest drain wound closure using knotless suture material is feasible based on the short-term results of the complication rate.

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 CTx was 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.

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.
