Application of indocyanine green fluorescence angiography in evaluating blood flow in rotator cuff tears: a preliminary study.

BACKGROUND: The relationship between the degree of vascularization at the edge of a torn rotator cuff tendon and cuff healing remains unclear. The purpose of this study was to employ indocyanine green (ICG) fluorescence angiography to evaluate the blood flow at the edge of a torn rotator cuff tendon under the subacromial view. METHODS: Thirteen shoulders of 13 patients who underwent arthroscopic repair of full-thickness rotator cuff tears were included in this prospective study. Viewing from the posterolateral portal, ICG at 0.2 mg/kg body weight was intravenously administered, and the blood flow was recorded. After resecting the poorly vascularized torn edge of the tendon, ICG administration was repeated at the same volume. The fluorescence intensity and perfusion time of the tendon blood flow were evaluated using video analysis and modeling tools. Cuff integrity was evaluated using magnetic resonance imaging at 6 months postoperatively. Patients were divided into healed and retear groups, and the differences in the degree of blood flow were evaluated. RESULTS: ICG fluorescence angiography could visualize the blood flow in the rotator cuff tendon, and the torn edge of the tendon with poor blood flow was resected. The overall retear rate was 23.1 % (3/13). Based on quantitative analysis, the fluorescence intensity factors were significantly lower in the retear group than in the healed group before tendon débridement. The retear rate in the high blood flow group was 0% (0/7), while that in the low blood flow group was 50.0% (3/6). CONCLUSIONS: ICG fluorescence angiography may play a role in the future of shoulder arthroscopy. Further study is needed to determine the effect of blood flow on tendon healing.

Efficacy of bone marrow stimulation for arthroscopic knotless suture bridge rotator cuff repair: a prospective randomized controlled trial.

BACKGROUND: The purpose of this study was to investigate the efficacy of bone marrow stimulation (BMS) on the repair integrity of the rotator cuff insertion treated with arthroscopic knotless suture bridge (K-SB) rotator cuff repair. We hypothesized that BMS during K-SB repair can improve the healing of the rotator cuff insertion. METHODS: Sixty patients who underwent arthroscopic K-SB repair of full-thickness rotator cuff tears were randomly allocated to 2 treatment groups. Patients in the BMS group underwent K-SB repair augmented with BMS at the footprint. Patients in the control group underwent K-SB repair without BMS. Cuff integrity and retear patterns were evaluated by postoperative magnetic resonance imaging. The clinical outcomes included the Japanese Orthopaedic Association score, University of California at Los Angeles score, Constant-Murley score, and Simple Shoulder Test. RESULTS: Clinical and radiological evaluations were completed in 60 patients at 6 months postoperatively, in 58 patients at 1 year postoperatively, and in 50 patients at 2 years postoperatively. Both treatment groups showed significant improvements in the clinical outcome from baseline to the 2-year follow-up, but no significant differences were found between the 2 groups. At 6 months postoperatively, the retear rate at the tendon insertion was 0.0% (0 of 30) in the BMS group and 3.3% (1 of 30) in the control group (P = .313). The retear rate at the musculotendinous junction was 26.7% (8 of 30) in the BMS group and 13.3% (4 of 30) in the control group (P = .197). All retears in the BMS group occurred at the musculotendinous junction, and the tendon insertion was preserved. There was no significant difference in the overall retear rate or retear patterns between the 2 treatment groups during the study period. CONCLUSIONS: No significant differences were detected in the structural integrity or retear patterns regardless of the use of BMS. The efficacy of BMS for arthroscopic K-SB rotator cuff repair was not proven in this randomized controlled trial.

Trastuzumab and fulvestrant combination therapy for women with advanced breast cancer positive for hormone receptor and human epidermal growth factor receptor 2: a retrospective single-center study.

BACKGROUND: Trastuzumab and fulvestrant combination therapy is one of the treatment options for patients with hormone receptor- and human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer; however, there are limited studies evaluating the efficacy of this combination therapy. METHODS: We retrospectively reviewed the data of women with hormone receptor- and HER2-positive metastatic breast cancer who received trastuzumab and fulvestrant combination therapy between August 1997 and August 2020 at the Cancer Institute Hospital. The primary endpoint of this study was progression-free survival, and the secondary endpoints were response rate, overall survival and safety. RESULTS: We reviewed the data of 1612 patients with recurrent or metastatic breast cancer, of which 118 patients were diagnosed with hormone receptor- and HER2-positive breast cancer. Of these, 28 patients who received trastuzumab and fulvestrant combination therapy were eligible for this study. The median treatment line for advanced breast cancer was 6 (range, 1-14), the median progression-free survival was 6.4 months (95% confidence interval [CI], 3.46-8.17), and the median overall survival was 35.3 months (95% CI, 20.0-46.7). Of the 28 patients, partial response was observed in 1 (4%), stable disease in 17 (61%), and progressive disease in 10 (36%) patients. The disease control rate was 64%. Adverse events of grade ≥ 3 were not observed. CONCLUSIONS: Trastuzumab and fulvestrant combination therapy showed moderate clinical efficacy and no severe toxicity after standard anti-HER2 treatment, which is a reasonable treatment option for patients with hormone receptor- and HER2-positive metastatic breast cancer. These data contribute to understanding the efficacy of trastuzumab and fulvestrant combination therapy as control data for further development of anti-HER2 agents plus hormone therapy.

Association between oral health and advisability of oral feeding in advanced cancer patients receiving palliative care: a cross-sectional study.

PURPOSE: Maintenance of oral feeding is important in terms of maintaining and improving the quality of life in terminal cancer patients receiving palliative care. Although adequate oral health status is essential for oral feeding in hospitalized patients, the relationship between oral health and oral feeding in patients receiving palliative care remains unclear. This cross-sectional study aimed to examine how the general condition and oral health status of these patients relate to decisions regarding their nutritional intake methods. METHODS: This retrospective cross-sectional study included 103 terminal cancer patients (59 men and 44 women; mean age, 73.8 ± 10.9 years) who received palliative care between April 2017 and August 2019. The nutritional method was assessed using the Functional Oral Intake Scale (FOIS). We assessed two types of nutritional methods: (1) the method advised by the attending physician until the initial dental examination (FOIS-I) and (2) the recommended method based on consultation with a palliative care doctor and dentist after the initial oral examination (FOIS-R). Furthermore, the participants' basic information and Dysphagia Severity Scale (DSS) and Oral Health Assessment Tool (OHAT) scores were assessed. RESULTS: There was a divergence between FOIS-I and FOIS-R. FOIS-R was significantly higher than FOIS-I (p < 0.001). Multiple regression analysis revealed that the time until death, DSS score, and OHAT score had a significant impact on determining the food form for oral feeding. CONCLUSIONS: Appropriate oral health assessment is important in determining the food form and indication for oral feeding among patients receiving palliative care.

Factors affecting the oral health of inpatients with advanced cancer in palliative care.

PURPOSE: Patients with terminal cancer undergoing multidisciplinary palliative care often have oral health problems, but these details are still unclear. This cross-sectional study aimed to elucidate the oral health of patients with terminal-stage cancer who are inpatient recipients of acute-phase palliative care, and to unveil the factors affecting their oral health. METHODS: Participants were 121 patients with terminal-stage cancer (68 males, 53 females, mean age: 73.6 ± 11.1 years) and oral health complaints. They received palliative care at Tokyo Medical and Dental University Medical Hospital between April 2017 and August 2019. Their demographic and medical details were extracted, retrospectively, from their medical records, and their oral health status, such as the number of natural teeth, removable denture usage, Oral Health Assessment Tool (OHAT), and Dysphagia Severity Scale, were evaluated. All outcomes were assessed by a dentist from the palliative care team. RESULTS: The problems with soft tissue, saliva, and oral cleanliness were observed. The absence of posterior occlusal support was common, and the use of removable dentures was often inadequate. In contrast, swallowing function was relatively well-conserved and 46.3% of the participants were capable of nutrition intake solely by mouth. Multiple regression analysis revealed a significant association between total OHAT score and age, consciousness level, prognostic level, and method of nutritional intake. CONCLUSION: The results revealed that the oral health of terminal cancer patients under palliative care declined despite receiving routine oral care from nurses, and suggest the importance of including dental professionals in multidisciplinary palliative care.

Influence of scapular neck length on the extent of impingement-free adduction after reverse total shoulder arthroplasty.

BACKGROUND: Following reverse total shoulder arthroplasty, a short scapular neck length (SNL) decreases postoperative impingement-free adduction, and impingement between the neck of the scapula and the humeral polyethylene cup may cause scapular notching. However, no reports have evaluated the influence of SNL on impingement-free adduction. The purposes of this study were to evaluate the influence of SNL on impingement-free adduction and to examine the effect of glenoid component lateralization and inferiorization on impingement-free adduction. METHODS: By use of 3-dimensional templating software, a virtual reverse total shoulder arthroplasty model was created in 15 patients who had no osteoarthritic change or any other bony deformity. We measured SNLs separately before implant placement (preoperative SNL) and after implant placement (postoperative SNL). The implant used was the Comprehensive Reverse Shoulder System (Zimmer Biomet, Warsaw, IN, USA), and baseplate bony lateralization of 0, 5, and 10 mm, with inferior eccentricity of 0.5 or 4.5 mm, was tested for impingement-free adduction. Correlations between the preoperative and postoperative SNLs and impingement-free adduction were analyzed. RESULTS: The mean preoperative SNL was 8.2 ± 1.9 mm (range, 5.0-11.7 mm), and the mean postoperative SNL was 6.0 ± 2.0 mm (range, 2.1-9.8 mm). There was a moderate correlation between the preoperative SNL and impingement-free adduction (r = 0.628, P = .12) and a strong correlation between the postoperative SNL and impingement-free adduction (r = 0.771, P = .001). Use of the model with 10 mm of bony lateralization and 4.5 mm of inferior eccentricity provided the best results in terms of impingement-free adduction. CONCLUSION: There were correlations between both the preoperative and postoperative SNLs and impingement-free adduction. Although the lateralized and inferiorized center of rotation may increase the risk of loosening of the glenoid component, this offset significantly increased impingement-free adduction.

Assessing the need for a question prompt list that encourages end-of-life discussions between patients with advanced cancer and their physicians: A focus group interview study.

OBJECTIVE: Early integration of palliative and cancer care improves the quality of life and is facilitated by discussions about the end of life after cessation of active cancer treatment between patients with advanced cancer and their physicians. However, both patients and physicians find end-of-life discussions challenging. The aim of this study was to assess the need for a question prompt list (QPL) that encourages end-of-life discussions between patients with advanced cancer and their physicians. METHODS: Focus group interviews (FGIs) were conducted with 18 participants comprising 5 pancreatic cancer patients, 3 family caregivers, 4 bereaved family members, and 6 physicians. Three themes were discussed: question items that should be included in the QPL that encourages end-of-life discussions with patients, family caregivers, and physicians after cessation of active cancer treatment; when the QPL should be provided; and who should provide the QPL. Each interview was audio-recorded, and content analysis was performed. RESULTS: The following 9 categories, with 57 question items, emerged from the FGIs: (1) preparing for the end of life, (2) treatment decision-making, (3) current and future quality of life, (4) current and future symptom management, (5) information on the transition to palliative care services, (6) coping with cancer, (7) caregivers' role, (8) psychological care, and (9) continuity of cancer care. Participants felt that the physician in charge of the patient's care and other medical staff should provide the QPL early during active cancer treatment. SIGNIFICANCE OF RESULTS: Data were collected to develop a QPL that encourages end-of-life discussions between patients with advanced cancer and their physicians.

[Future Cancer Professional Training Plan].

As one of the 11 third-stage"cancer professional plan", we will outline the activities and results of the"Future Cancer Professional Training Plan"consisting of 8 universities in the Tokyo metropolitan area and the Northern Tohoku area of Japan. In this project, as joint activities of 8 universities, we held the activity reports and joint symposiums with faculty/student exchange meetings at the management council twice a year. In addition, joint international symposiums with other cancer professional hub were held. We carried out subcommittee activities for each theme. In the graduate school courses of each university, we provided education with various contents and exchanged credits between universities. We also focused on holding seminars and public lectures, and collaborating with patients'association. These activities were reflected for the next year based on the results of the annual external evaluation.

Oral infectious bacteria in dental plaque and saliva as risk factors in patients with esophageal cancer.

BACKGROUND: High levels of periodontopathic bacteria as well as Streptococcus anginosus were detected in cancer tissue from patients with esophageal cancer. An association between oral infectious bacteria and esophageal cancer has been reported. METHODS: Characteristics of the oral microbiota and periodontal conditions were studied as clinicopathologic factors in patients with esophageal cancer. The study included 61 patients with esophageal cancer and 62 matched individuals without any cancers. Samples of subgingival dental plaque and unstimulated saliva were collected to evaluate the prevalence and abundance of the following oral bacteria using a real-time polymerase chain reaction assay: Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, Treponema denticola, and S. anginosus. RESULTS: In the cancer group, the prevalence of all bacteria, with the exception of F. nucleatum, in dental plaque; the prevalence of A. actinomycetemcomitans in saliva; the abundance of all bacteria, with the exception of F. nucleatum and P. intermedia, in dental plaque; and the abundance of A. actinomycetemcomitans and S. anginosus in saliva were significantly higher. Furthermore, a logistic regression analysis suggested that the prevalence of T. forsythia and S. anginosus in dental plaque and of A. actinomycetemcomitans in saliva, as well as a drinking habit, were associated with a high risk of esophageal cancer, with a high odds ratio. CONCLUSIONS: The current findings have potential implications for the early diagnosis of esophageal cancer.

A Pilot Study Analyzing the Clinical Utility of Comprehensive Genomic Profiling Using Plasma Cell-Free DNA for Solid Tumor Patients in Japan (PROFILE Study).

BACKGROUND: The clinical utility of plasma cell-free DNA in precision cancer medicine has not been established. A pilot study was conducted to investigate the clinical utility of comprehensive genomic profiling by liquid biopsy in a Japanese population. METHODS: In this PROFILE study, 102 patients with advanced solid tumors who showed progression with standard systemic therapy underwent liquid biopsy between August 2017 and February 2020. Liquid biopsy was performed using Guardant360. RESULTS: Of the 102 patients, 56 were women, and the median age was 65 years. Regarding the types of cancer, 31 were hepatobiliary and pancreatic cancer, 17 were gastrointestinal cancer, and 13 were breast cancer. Frequently altered genes were TP53 (53.9%, 46/102), KRAS (25.5%, 26/102), PIK3CA (19.6%, 20/102), and EGFR (17.6%, 18/102). At least one genetic aberration was detected in 92 patients (90.2%). Actionable mutation was discovered in 88 patients (86.3%), and 67 patients (65.7%) were clinical trial candidates. Of the 102 patients, 22 (21.6%) were able to receive biomarker-matched therapy. Their best responses were as follows: 1 complete response, 3 partial responses, 7 stable diseases, and 11 progressive diseases. Additionally, the treated patients were divided on the basis of matching scores (≥ 50% vs. < 50%). The patients were divided into high and low groups. The high group had a higher disease control rate (DCR) of 75% compared with 20% in the low group (P = 0.010). CONCLUSIONS: The results indicate that liquid biopsy is useful for identifying actionable mutations associated with the clinical response of selected patients.

Effects of parenteral nutrition and hydration on survival in advanced cancer patients with malignant bowel obstruction: secondary analysis of a multicenter prospective cohort study.

PURPOSE: The benefits of parenteral nutrition and hydration (PNH) in patients with advanced cancer remain unknown. Therefore, we conducted a prospective multicenter cohort study to assess the effects of PNH on survival in patients with malignant bowel obstruction (MBO). METHODS: The present study was a secondary analysis. Data on primary nutritional administration routes during the first week of admission to palliative care units, i.e., parenteral nutrition and parenteral hydration, were obtained. Data on the averaged calorie sufficiency rate/total calorie intake (75% ≤ or 750 kcal/day ≤ , 50-75% or 500-750 kcal/day, 25-50% or 250-500 kcal/day, and < 25% or < 250 kcal/day) were also obtained. Participants with MBO were included and divided into two groups: PNH-high (25% ≤ or 250 kcal/day ≤) and PNH-low (< 25% or < 250 kcal/day). We performed time-to-event analyses using the Kaplan-Meier method, log-rank test, and univariate and multivariate Cox regression analyses. RESULTS: Patients were divided into the PNH-high (n = 68) and PNH-low (n = 76) groups. A significant difference was observed in survival rates between the two groups (log-rank P < 0.001). Median survival times were 35.5 (95% CI 27-44) and 17.5 (95% CI 13-21) days, respectively. In the multivariate-adjusted model, a significantly lower risk of mortality was observed in Cox's proportional hazard model in the PNH-high group (HR 0.55 (95% CI 0.36-0.83), P = 0.005) than in the PNH-low group. CONCLUSION: The present results indicated the beneficial effects of PNH for prolonging survival in advanced cancer patients with MBO in palliative care units.

Where and what damage occurs at the acromial undersurface in patients with rotator cuff tears?

BACKGROUND: The gross pathology of the acromial undersurface in shoulders with rotator cuff tears with subacromial impingement is not completely understood. Many researchers have focused on damage to the anterior one-third area of the acromial undersurface, but few have studied the middle and posterior one-third areas. The purpose of this study was to clarify where and what damage occurs at the acromial undersurface in patients with rotator cuff tears. METHODS: We performed arthroscopic shoulder (n = 182, all with rotator cuff tears; mean age, 64.9 ± 8.4 years) and cadaveric shoulder (n = 23, 14 intact cuffs and 9 rotator cuff tears; mean age, 74.8 years) evaluations to observe the extent and degree of damage to the acromial undersurface. We statistically analyzed the association between the severity of the damage to the acromial undersurface (assessed using the Copeland-Levy classification as A0, normal; A1, minor scuffing; A2, major damage; or A3, visualization of bare bone area) and rotator cuff tear size (assessed using the classification of DeOrio and Cofield as partial; small, <1 cm; medium, 1-3 cm; or large or massive, >3 cm). RESULTS: The anterior, middle, and posterior one-thirds of the acromial undersurface were somewhat damaged (class A1-A3) in 92.6%, 90.1%, and 78.6% of shoulders with rotator cuff tears, respectively, according to arthroscopic evaluation. Increasing cuff tear size was significantly associated with worsening degree of damage to the acromial undersurface (P < .001). In the 9 cadaveric shoulders with rotator cuff tears, class A1-A3 damage was identified in the anterior one-third area in 100%, in the middle one-third area in 88.9%, and in the posterior one-third area in 33.3%. In the 14 cadaveric shoulders with a normal rotator cuff, class A1-A3 damage was identified in the anterior one-third area in 35.7%, in the middle one-third area in 14.3%, and in the posterior one-third area in 0.71%. CONCLUSION: Damage to the acromial undersurface in patients with rotator cuff tears occurred at the middle, posterior, and anterior one-third areas, and the degree of damage was related to cuff tear size. Surgeons should evaluate the entire acromial undersurface to check for subacromial impingement damage at the middle and posterior one-third areas as well as the anterior one-third area of the acromial undersurface; this might aid in the treatment of patients with rotator cuff disease or subacromial impingement syndrome.

[Clinical Utility of Comprehensive Genome Profiling Using FoundationOne CDx in Japanese Population(PROFILE-F Study)].

BACKGROUND: FoundationOne CDx is a cancer genome profiling test that has already been approved by the FDA, but its clinical utility in Japanese patients is unknown. In this study, we examined the clinical utility of FoundationOne CDx. METHODS: 46 samples from 43 Japanese pretreated patients with advanced solid tumors were tested with FoundationOne CDx between September 2018-January 2019. RESULTS: The median age of 43 patients was 63 years(ranged 18 to 82 years), and among them 24 were males and 19 females. Major cancer types were hepato-biliary and pancreatic(8 cases)and other digestive organs(8 cases). All 27 cases in which genome cancer board had been completed by January 17, 2019 were analyzable, and the number of detected gene mutations(except VUS)was an average of 4.3(ranged 0 to 14)per case. Of the 27 cases, one or more mutations were found in 26 cases(96%), and in all such 26 cases actionable mutations with candidates for therapeutic agents were found. In 4(15%)of them, the treatment corresponding to the gene mutation was performed. Among the cases in which target disease matched and clinical trials of the drug were being conducted in Japan, only one case participated in the trial. The most common reason for not participating in the trial was disease deterioration and PS reduction (33%). CONCLUSIONS: The FoundationOne CDx test showed that it can detect gene mutations in various cancer types in Japanese patients.

A survey of palliative medicine education in Japan's undergraduate medical curriculum.

BACKGROUND: This study aimed to examine the status of undergraduate palliative care education among Japanese medical students using data from a survey conducted in 2015. METHODS: A questionnaire was originally developed, and the survey forms were sent to universities. The study's objectives, methods, disclosure of results, and anonymity were explained to participating universities in writing. Responses returned by the universities were considered to indicate consent to participate. Descriptive statistical methodology was employed. RESULTS: The response rate was 82.5% (66 of 80 medical faculties and colleges). Palliative care lectures were implemented in 98.5% of the institutions. Regarding lecture titles, "palliative medicine," "palliative care," and "terminal care" accounted for 42.4, 30.3, and 9.1% of the lectures, respectively. Teachers from the Department of Anesthesia, Palliative Care, and Psychiatry administered 51.5, 47.0, and 28.8% of lectures, respectively. Subjects of lectures included general palliative care (81.8%), pain management (87.9%), and symptom management (63.6%). Clinical clerkship on palliative care was a compulsory and non-compulsory course in 43.9 and 25.8% of the schools, respectively; 30.3% had no clinical clerkship curriculum. CONCLUSIONS: Undergraduate palliative care education is implemented in many Japanese universities. Clinical clerkship combined with participation in actual medical practice should be further improved by establishing a medical education certification system in compliance with the international standards.

[THE POTENTIAL ROLE OF SOCIAL NETWORK ANALYSIS IN TUBERCULOSIS CONTACT INVESTIGATION].

[Aim] To explore the possible role of social network analysis (SNA) in identifying infected contacts and visualizing data in a tuberculosis (TB) contact investigation. [Method] We analyzed TB contact investigation data from an outbreak in a Japanese language school in Tokyo, Japan, in 20XX. Information on places which the index case and his contacts commonly shared was collected in line with the data collected routinely in contact investigation. Average hours of exposure to the index case were calculated for each contact by using SNA software, and the relationship to the index case via commonly shared places was visualized as a sociogram. Statistical analysis was performed to. compare the exposure hours and TB infection statuses, between those . infected, including active TB and latent TB infection (LTBI), and non- infected contacts. [Result] The data on the index TB case and 41 contacts, of whom 5 and 10 were diagnosed with active TB and LTBI, were analyzed. Contacts with active TB and LTBI had 12.5 and 11.5 times longer median hours of exposure, which were significantly longer compared to non-infected contacts. The sociogram summarized the network of index TB case, contacts characterized by exposure hours and infection statuses, and the places shared by the index case and the contacts. [Discussion] SNA analysis was considered to be useful in prioritizing contacts in a TB contact investigation, in assisting interpretation of indeterminate Interferon-Gamma release assay test results, in estimating places where transmission occurred, and visualizing data accrued in TB contact inves- tigations.

Retrospective Analyses of Esophageal Bypass Surgery for Patients with Esophagorespiratory Fistulas Caused by Esophageal Carcinomas.

BACKGROUND: Esophagorespiratory fistula (ERF) caused by esophageal carcinoma is a fatal complication. In our institution, esophageal bypass surgery has been indicated when possible. We herein retrospectively describe the clinical results of esophageal bypass surgery for ERF. PATIENTS AND METHODS: Between April 2001 and March 2015, 20 patients with ERF underwent esophageal bypass surgery. For these patients, the clinical safety, validity, and effectiveness of esophageal bypass surgery were examined and compared with the results of bypass surgery without ERF. RESULTS: Eight patients developed ERF at the initial diagnosis, while 10 patients developed ERF during and after chemoradiotherapy. Postoperative complications such as pneumonia, surgical site infection, and anastomotic leakage developed in 12, 5, and 1 patient, respectively. All the patients could eat solid foods at a median of 9 postoperative days. Two patients died within 30 days after the operation and 1 patient developed in-hospital death. Fourteen patients received chemo(radio)therapy after the operation. The median overall survival was 244 days and the one-year and three-year overall survival rates were 45.7 and 15.3 %, respectively. There was no significant difference in terms of the intraoperative findings, postoperative morbidities, and short-term and long-term clinical results between the two groups. CONCLUSION: Esophageal bypass surgery for ERF is not considered to be highly invasive or risky compared with bypass surgery without ERF. After the operation, respiratory symptoms caused by ERF may improve and oral intake can be achieved. Esophageal bypass surgery should therefore be aggressively performed for patients with a tolerable performance status.

Prognostic Factors for Post-Recurrence Survival in Patients with Thoracic Esophageal Squamous Cell Carcinoma after Curative Resection.

BACKGROUND/AIMS: We investigated factors affecting the post-recurrence prognosis in order to develop adequate therapeutic guidelines for determining the indication for treatment of recurrent esophageal squamous cell carcinoma (ESCC). METHODS: Ninety-three thoracic ESCC patients who developed postoperative recurrence after undergoing curative esophagectomy with 3-field lymphadenectomy at our institute and who received treatment for recurrence were enrolled in this study. RESULTS: A univariate analysis showed that distant organ recurrence, the number of recurrent tumors, the longest diameter of the largest recurrent tumor, the sum of all of the longest diameters of the recurrent tumors, invasion into adjacent structures and the speed of growth of the representative recurrent tumors were significantly associated with the post-recurrence prognosis. A multivariate analysis showed that distant organ recurrence, the longest diameter of the largest recurrent tumor, invasion into adjacent structures and the speed of growth of the representative recurrent tumors were significantly associated with the prognosis. The patients whose recurrent tumor(s) did not meet all 4 of these factors showed a better prognosis. In contrast, the prognosis of the patients whose recurrent tumor(s) demonstrated all 4 factors was almost the same as that observed in the patients who did not receive any treatment for recurrence. CONCLUSIONS: The evaluation of these 4 factors may potentially be used to determine the indication for treatment for recurrence.

Palliative medicine as active cancer therapy support.

Active cancer therapy consists of surgery, radiation and chemotherapy. The meaning of palliative cancer care have been changed from end-of-life care to accomplishment of better QOL of cancer patients and their family from the period of diagnosis and early treatment. Palliative medicine as active cancer therapy support includes not only supportive care for the adverse events of active cancer therapy but also shared decision making with patients and family. Concordance was originally proposed by pharmacists as a term to achieve better adherence for drugs. It is also applied to team approach for cancer therapy that patients and family are also the team members.

Serial Magnetic Resonance Arthrography for a Midsubstance Capsular Tear in a Patient With Traumatic Anterior Shoulder Instability.

The natural history of midsubstance capsular tears (MCTs) is unclear. We herein describe a case of MCT observed using serial magnetic resonance (MR) arthrography. A 46-year-old woman presented with excessive external rotation of the left glenohumeral joint, resulting in an initial anterior dislocation of the left shoulder. She subsequently developed recurrent shoulder joint dislocations. MR arthrography revealed an MCT without a Bankart lesion three months after the initial dislocation. She opted for nonoperative treatment, but the shoulder instability did not improve. The second MR arthrography, nine months after the initial dislocation, showed no natural healing of the MCT. The third MR arthrography, 12 months after the initial dislocation, also showed no natural healing. Her shoulder instability remained persistent. The patient then decided to have surgery. Arthroscopy revealed a large capsular defect extending from the glenoid to the humeral head in the anterior inferior glenohumeral ligamentous complex. The MCT was repaired with the placement of nonabsorbable sutures in a side-to-side fashion. At the final follow-up, three years postoperatively, the patient had no anterior shoulder instability. The Rowe score was 100 points. MR arthrography showed good repair integrity of the MCT at one year postoperatively. Serial MR arthrography was useful for both the patient and the shoulder surgeon in considering the treatment of the MCT, facilitating an accurate and qualitative assessment of whether natural healing of the MCT had been achieved.
