OBJECTIVE: To evaluate whether pathologic complete response (pCR) exclusively defines major pathologic response to treatment with improved survival. SUMMARY BACKGROUND DATA: pCR following trimodality therapy for esophagogastric adenocarcinoma is infrequent but associated with improved prognosis. Yet most clinical trials and correlative studies designate pCR as the primary endpoint. METHODS: We analyzed our prospectively maintained database for patients who underwent trimodality therapy for locally advanced esophageal adenocarcinoma between 1995 and 2017. Overall survival (OS) was examined by percentage treatment response (TR) in the primary tumor bed and pathologic nodal stage (ypN0) using Kaplan-Meier plots. Optimal thresholds of TR for differentiating patients in terms of OS were investigated with descriptive plots using restricted cubic spline functions; associations were quantified using Cox multivariable analysis. RESULTS: Among 788 patients, median follow-up was 37.5 months (range, 0.4–210.6); median OS was 48.3 months (95% CI, 42.2–58.8). Absence of residual nodal disease was independently associated with improved survival (P

The management of non-small-cell lung cancer (NSCLC) varies according to stage. Surgical resection is reserved for operable patients with early-stage NSCLC, while high-dose target radiation-stereotactic body radiation therapy (SBRT)-is reserved for patients whose comorbidities prohibit them from a major surgical procedure. The treatment of locally advanced NSCLC (LA-NSCLC) is stratified according to resectability. Those with resectable disease may require additional treatments such as chemotherapy and radiation, while patients with unresectable disease will require definitive chemoradiation therapy with adjuvant durvalumab. Patients with limited metastatic disease benefit from the combination of SBRT and systemic therapy.

Approximately 12% of routinely examined fallopian tubes of endometrial carcinoma (EC) cases have intraluminal tumor cells (ILTCs). ILTC associations with EC characteristics and outcomes are understudied, and unknown in serially examined and embedded tubal fimbriae. Glass slides of serially examined and embedded tubal fimbriae for 371 EC cases were independently reviewed by 2 pathologists who recorded ILTC presence and characterized them as mucosal if involved and floating if not. Disagreements were reviewed by a third pathologist, and agreement between any 2 determined final ILTC status. Clinico-pathologic associations and ILTC presence were tested for significance (P

Objective To conduct a population-level analysis of temporal trends and risk factors for high symptom burden in patients receiving surgery for non-small-cell lung cancer (NSCLC). Summary background data A population-level overview of symptoms after curative intent surgery is necessary to inform decision making and supportive care for patients with lung cancer. Methods Retrospective cohort study of patients receiving surgery for stage I-III NSCLC between January 2007-September 2018. Prospectively collection Edmonton Symptom Assessment System (ESAS) scores, linked to provincial administrative data, were used to describe the prevalence, trajectory and predictors of moderate-to-severe symptoms in the year following surgery. Results A total of 5,350 patients, with 28,490 unique ESAS assessments, were included in the analysis. Moderate-to-severe tiredness (68%), poor wellbeing (63%) and shortness of breath (60%) were the most common symptoms reported. The rise and fall in the proportion of patients experiencing moderate-to-severe symptoms after surgery coincided with the median time to first (58 days, IQR: 47-72) and last cycle of chemotherapy (140 days, IQR: 118-168), respectively. There was eventual stabilization, albeit above the pre-operative baseline, within 6-7 months after surgery. Female sex (RR 1.09-1.26), lower income (RR 1.08-1.23), stage III disease (RR 1.15-1.43), adjuvant therapy (RR 1.09-1.42), chemotherapy within two weeks of an ESAS assessment (RR 1.14-1.73), and pneumonectomy (RR 1.05-1.15) were associated with moderate-to-severe symptoms following surgery. Conclusions Knowledge of population-level prevalence, trajectory and predictors of moderate-to-severe symptoms after surgery for NSCLC can be used to facilitate shared decision making and improve symptom management throughout the course of illness.

BACKGROUND: Colon cancer affects a patient's ability to work. Many patients who have colon cancer are employed at the time of diagnosis.OBJECTIVE: We evaluated work ability during the first 2 years after colon cancer diagnosis.DESIGN: This study is a national prospective study, the Prospective Dutch ColoRectal Cancer cohort, including clinical data and patient-reported outcomes.SETTINGS: Data were collected in 59 medical centers in the Netherlands.PATIENTS: Patients MAIN OUTCOME MEASURES: Work ability was assessed at baseline, 3, 6, 12, 18, and 24 months. The Work Ability Index (range, 0 to 49) was evaluated using linear mixed models. Outcomes were matched to population controls without cancer.RESULTS: Of 390 patients, 84% had paid employment. Work ability of patients with stage I to IV colon cancer was significantly lower at the time of diagnosis than in matched population controls (31 ± 8.2 and 41 ± 5.6). Patients with stage I to III disease receiving surgery only regained Work Ability Index scores comparable to matched population controls at 18 months. Patients receiving adjuvant systemic treatment initially demonstrated a decrease in work ability with improvements from 6 months onward and normalization at 24 months. Patients with stage IV disease did not demonstrate improvements in work ability outcomes over time. Work ability scores were negatively influenced by the administration of systemic treatment and ≥1 comorbidities.LIMITATIONS: Only patients with patient-reported outcomes and work at baseline were included in this analysis. Also, questionnaire response rates decreased over time.CONCLUSIONS: Work ability in patients with colon cancer is decreased for a prolonged time. Recovery depends on disease stage, type of treatment, and comorbidities. Patients with stage I to III disease treated with curative surgery alone were the first to regain work ability, followed by patients who receive adjuvant chemotherapy. Patients with stage IV disease did not regain work ability.

Muchos pacientes con cáncer de colon están empleados en el momento del diagnóstico.OBJETIVO:Evaluamos la capacidad laboral durante los dos primeros años posteriores al diagnóstico de cáncer de colon.DISEÑO:Es un estudio prospectivo nacional, la cohorte de cáncer colorrectal holandés, incluye datos clínicos y resultados informados por los pacientes.ENTORNO CLINICO:Se recopilaron datos de 59 centros médicos en los Países Bajos.PACIENTES:Se seleccionaron pacientes < 67 años, con cáncer de colon en estadio I-IV, que completaron los cuestionarios de índice de capacidad para el trabajo.PRINCIPALES MEDIDAS DE VALORACIÓN:La capacidad para el trabajo se evaluó al inicio, a los 3, 6, 12, 18 y 24 meses. El índice de capacidad para el trabajo (que va de 0 a 49) se evaluó mediante modelos lineales mixtos. Los resultados fueron comparados con el grupo control sin cáncer.RESULTADOS:De 390 pacientes, el 84% tenía un empleo remunerado. La capacidad de trabajo de los pacientes en estadio I-IV fue significativamente menor en el momento del diagnóstico en comparación con el grupo control (31 ± 8,2 y 41 ± 5,6, respectivamente). Los pacientes con enfermedad en estadio I-III que recibieron cirugía lograron recuperar puntajes del índice de capacidad laboral comparables a los controles a los 18 meses. Los pacientes que recibieron tratamiento sistémico adyuvante inicialmente demostraron una disminución en la capacidad de trabajo con mejoras a partir de los 6 meses en adelante y una normalización a los 24 meses. Los pacientes en estadio IV no demostraron mejoras en los resultados de la capacidad laboral a lo largo del tiempo. Las puntuaciones de capacidad para el trabajo se vieron influidas negativamente por la administración del tratamiento sistémico y la existencia de ≥1 comorbilidades.LIMITACIONES:En este análisis solo se incluyeron los pacientes con resultados y trabajo desde el inicio del estudio. Además, las tasas de respuesta al cuestionario disminuyeron con el tiempo.CONCLUSIONES:La capacidad de trabajo en pacientes con cáncer de colon se reduce durante un tiempo prolongado. La recuperación depende del estadio de la enfermedad, el tipo de tratamiento y la comorbilidad. Los pacientes con enfermedad en estadio I-III tratados con cirugía curativa exclusivamente, son los primeros en recuperar la capacidad para trabajar, seguidos de los pacientes que reciben quimioterapia adyuvante. Los pacientes con enfermedad en estadio IV no recuperan la capacidad para trabajar. Consulte Video Resumen en http://links.lww.com/DCR/B759 . (Traducción- Dr. Ingrid Melo ).

Objective Guidelines for muscle-invasive bladder cancer (MIBC) recommends that patients receive neoadjuvant chemotherapy with radical cystectomy as treatment over radical cystectomy alone. Though trends and practice patterns of MIBC have been defined using the National Cancer Database, data using the Surveillance, Epidemiology, and End Results (SEER) program have been poorly described. Methods Using the SEER database, we collected data of MIBC according to the American Joint Commission on Cancer (AJCC). We considered differences in patient demographics and tumor characteristics based on three treatment groups: Chemotherapy (both adjuvant and neoadjuvant) with radical cystectomy, radical cystectomy, and chemoradiotherapy. Multinomial logistic regression was performed to compare likelihood ratios. Temporal trends were included for each treatment group. Kaplan–Meier curves were performed to compare cause-specific survival. A Cox proportional-hazards model was utilized to describe predictors of survival. Results Of 16 728 patients, 10 468 patients received radical cystectomy alone, 3236 received chemotherapy with radical cystectomy, and 3024 received chemoradiotherapy. Patients who received chemoradiotherapy over radical cystectomy were older and more likely to be African American; stage III patients tended to be divorced. Patients who received chemotherapy with radical cystectomy tended to be males; stage II patients were less likely to be Asian than White. Stage III patients were less likely to receive chemoradiotherapy as a treatment option than stage II. Chemotherapy with radical cystectomy and chemoradiotherapy are both underutilized treatment options, though increasingly utilized. Kaplan–Meier survival curves showed significant differences between stage II and III tumors at each interval. A Cox proportional-hazards model showed differences in gender, tumor stage, treatment modality, age, and marital status. Conclusions Radical cystectomy alone is still the most commonly used treatment for muscle-invasive bladder cancer based on temporal trends. Significant disparities exist in those who receive radical cystectomy over chemoradiotherapy for treatment.

Breasts are one of the secondary sexual characteristics in females. They are the rout for of nutrition & growing of infant till 4-6 months of age. Breast diseases are one of the most common diseases in the females of any society. Multiple types of benign breast lesions like fibroadenomas, simple cyst, breast abscess, lymph nodes enlargement and different malignancies are common pathologies of the breast. Up to 30% of women suffer from benign breast disease at any time of their life and this compels them to take the treatment. The prospective clinical study was achieved for 283 women ( age was ranged between 20 60 years) had palpable breast lesion referred by their managing surgeons to the radiological department at Azadi Teaching Hospital, for a period of 8 months (from January 2018 to August of the same year). The study depended firstly in all women on clinical examination/self-breast examination. Results:- 283 patients were included in this study with age between 20 _ 60 ys, most of the patients were diagnosed as fibroadenoma which is most common around 54.9% of the total cases studied, Fibrocystic diseases (Duct ectasia, cysts, and galactocele ) 19.3 %.Followed by infection as mastitis 15.4%, and phyllodes tumor less than 1% approximately and finally carcinoma 9.5%. In conclusions, the results of our study are encouraging to applying the US for masses for differentiating if it pointing to benignant or malignancy status and sonography shouldn't be generally applied to defer the biopsy of a solid mass.

Aims. The relationship of tumour volume, radiotherapy treatment time and other prognostic factors affecting prognosis was evaluated. Methods. 184 patients with locally advanced head and neck cancer were treated with radical intensity modulated radiotherapy (IMRT) and compared retrospectively. Results. In the multivariate analysis the overall survival was dependent on gross tumour volume (GTV), clinical stage (CS), radiotherapy treatment time (RTT) and p16 status. Local control was influenced by GTV, overall RTT and age. DFS was significantly affected by GTV, CS, RTT, p16 status and concomitant chemotherapy (CHT). Conclusions. The tumour volume and the radiotherapy treatment time were the most significant prognostic factors with the best outcomes in patients with GTV ≤ 55 cc and RTT ≤ 48 days (mean LC 8.1, DFS 7.1 and OS 6.4 years) and worst outcomes with GTV > 55 cc and RTT >48 days (mean LC 4.4, mean DFS 3.2 and mean OS 2.6 years).

Collecting duct carcinoma of the kidney is a rare and aggressive subtype of renal cell carcinoma (RCC) arising from the distal convoluted tubules. At the time of diagnosis, patients are more frequently symptomatic, with advanced locoregional stage, and have metastatic disease. The 2016 WHO Classification of Tumours of the Urinary System defined diagnostic criteria for this entity. However, the diagnostic features continue to evolve, with typical, but not entirely specific, histologic and immunophenotypic characteristics. In addition, the lack of consistent molecular alterations makes collecting duct carcinoma a diagnosis of exclusion, with historical cases being re-classified as fumarate hydratase deficient RCC, ALK rearranged RCC, renal medullary carcinoma or high-grade urothelial carcinoma. The rarity and poor prognosis of the tumor makes it difficult to reach consensus guidelines to guide therapy. In this manuscript we review the clinicopathologic features of collecting duct carcinoma including pathologic diagnostic criteria, molecular characteristics and differential diagnosis, and their possible implications for management.

BACKGROUND Many patients with papillary thyroid cancer (PTC) demonstrate satisfactory outcomes. However, 8%-28% of patients with PTC show tumor recurrence, which may affect prognosis. Therefore, identifying factors associated with tumor recurrence in patients with PTC may be helpful to refine therapeutic strategies. PATIENTS AND METHODS To identify factors associated with PTC recurrence, we retrospectively reviewed demographic features (sex and age), operation method, image character, serum thyroglobulin (Tg), accumulated radioactive iodine (I-131) therapeutic dose, I-131 uptake, and metastases at diagnosis in 829 patients with PTC. Patients were grouped into early (stage I and II; n = 698) and advanced (stage III and IV; n = 131) tumor-node-metastasis (TNM) stages. Recurrence rate, mortality rate, risk factors of recurrence, recurrent free survival and overall survival curve were compared between two groups. RESULTS Patients in the early stage demonstrated a lower recurrence rate (7.2%) than did those in the advanced stage (28.2%, p < 0.05). The mortality rate of patients with recurrence in the advanced stage was higher than that of those in the early stage (51.4% vs. 12.0%). The major impact factors on tumor recurrence in early TNM stage were distant metastasis and lymph node metastasis, while in advanced TNM stage were distant metastasis, male gender, total thyroidectomy with limited lymph node dissection, and a high serum Tg level. CONCLUSIONS Strategies to monitor tumor recurrence might be refined according to the TNM stages of PTC patients.

Summary Aim of the study Nomograms have been proposed to assess prognosis following curative surgery for gastric cancer. The objective of the current study was to evaluate the performance of the Gastric Cancer Collaborative Group nomograms developed in 2014 by Kim et al., using a cohort of patients from a 10-year single institution experience in gastric cancer management. Patients and methods We retrospectively reviewed patients who underwent curative-intent surgery for histologically confirmed gastric cancer at First Surgical Clinic of Padua University Hospital (Italy) from January 2010 to May 2020. Univariable and multivariable Cox proportional hazard models were employed to assess the effect of the variables of interest on mortality and recurrence. Multivariable analysis was performed by considering the variables included in the Gastric Cancer Collaborative Group nomograms in order to validate them. The performance of the nomograms was evaluated using Harrell's C-index and calibration plots. Results Overall, 168 patients were included, with a median follow-up of 20.1 months. On multivariable analysis, tumor location, lymph node ratio, and pathological T stage were associated with recurrence; age, tumor location, lymph node ratio, and pT stage were associated with OS (overall survival). The nomograms had good discriminatory capability to classify both OS (C-index: 0.75) and DFS (disease-free survival) (C-index 0.72). The corrected C-Index for DFS based on the AJCC staging system revealed better prediction (C-Index 0.75), while the corrected C-Index for OS had worse discrimination ability compared with the current nomogram (C-Index 0.72). Conclusions The Gastric Cancer Collaborative Group nomograms demonstrated good performances in terms of prediction of both OS and DFS on external validation. The two nomograms are easy to apply, and variables included are widely available to most facilities.

Objective This study aimed to investigate the demographic and clinicopathological characteristics, and survival outcomes of subglottic Squamous Cell Carcinoma (SCC) based on the Surveillance, Epidemiology, and End Results (SEER) database. Methods Demographic and clinicopathological information, including age, sex, race, tumor size, histologic grade, clinical/TNM stage, tumor invasion extent, Lymph Node Metastasis (LNM) extent, size of metastatic lymph nodes, LNM ratio and treatment data, of 842 subglottic SCC patients diagnosed between 1996 and 2016 were acquired. Kaplan-Meier survival analyses were performed to assess the effects of clinicopathological characteristics, treatment modalities, surgical procedures, and adjuvant therapies on overall survival and cancer-specific survival. Results Subglottic SCC was more frequent among males aged 60-70 years, with low-grade but locally advanced lesions without local or distant metastases. Age and several primary tumor/LNM related variables were independent risk factors for overall survival and cancer specific survival. Advanced-stage and high-grade disease led to unfavorable prognosis. The most common treatment modality and surgical procedure were surgery plus radiotherapy and total laryngectomy, respectively. Surgery plus radiotherapy provided favorable 5-year survival outcomes, while total laryngectomy had the worst. Surgery plus adjuvant therapy showed better survival outcomes than surgery alone. Conclusion This study confirmed the rarity of subglottic SCC. Patients with subglottic SCCs suffered poor prognosis especially for those with advanced-stage or high-grade lesions. The prognosis of subglottic SCC remained poor over the years, despite recent progress in cancer therapies. Surgery plus adjuvant therapy improved the survival outcome. Although larynx preservation surgery was beneficial for early-stage disease, total laryngectomy was favored for patients with advanced tumors. Level of evidence Level 4.

Introduction Lysyl oxidase-like 4 is an amine oxidase from the lysyl oxidase family that was previously shown to be overexpressed in head and neck cancer and upregulated in response to hypoxia. The possible role of lysyl oxidase-like 4 as a tumor marker in advanced stage larynx cancer was investigated. Objective To investigate the expression of lysyl Oxidase-Like 4 protein in advanced stage laryngeal cancer and elucidate its possible role as a tumor marker, predictor of treatment response and prognosticator. Methods Diagnostic specimens of 72 patients treated for stage III–IV laryngeal squamous cell carcinoma were evaluated for lysyl oxidase-like 4 expression by immunohistochemistry. Results Lysyl oxidase-like 4 expression was correlated with advanced tumor stage (p = 0.041) and better differentiation (p = 0.025) but was independent of tumor diameter (p = 0.456). Response to induction chemotherapy or the need for salvage laryngectomy were not affected by lysyl oxidase-like 4 expression (p = 0.999, p = 0.070 respectively). Increased lysyl oxidase-like 4 expression was associated with better 2 year overall survival in both univariate (p = 0.036) and multivariate analyses (p = 0.014). Conclusion Lysyl oxidase-like 4 expression emerges with advancing stages, is lost with worsening differentiation, and may have tumor suppressive properties in larynx cancer.

Objective The prognostic importance of minichromosome maintenance complex expression in nasopharyngeal cancer is still unknown. We aimed to find whether minichromosome maintenance complex 2–7 expression may potentially be used to predict the prognosis of nasopharyngeal cancer patients treated with definitive radiotherapy. Methods Between April 2007 and July 2020, patients with nasopharyngeal cancer treated with radiotherapy were identified. Immunohistochemical analysis was performed on formalin-fixed paraffin-embedded tissues of cases. A single pathologist analyzed the histologic specimens of all patients. Results Totally, 67 patients were included. The median followup was 75.3 months. Higher tumor (T) stage was correlated with minichromosome maintenance complex 2 overexpression. Minichromosome maintenance complex s expression was also associated with histopathologic subgroups. According to univariate analysis, AJCC stage, histopathological subgroups, tumor response after treatment, minichromosome maintenance complex 2, 3, 5, 6 and 7 expression were the prognostic factors that predict overall survival. According to multivariate analysis minichromosome maintenance complex 7 expression was the only prognostic marker for both progression-free survival and overall survival. Conclusion The overexpression of minichromosome maintenance complex 2, 3, 5, 6 and 7 indicated bad prognosis. Minichromosome maintenance complex 7 was an independent prognostic factor for survival outcomes in nasopharyngeal cancer and may be a potential therapeutic target for treatment.

PurposeEstrogen receptor (ER) expression in breast cancer plays an essential role in carcinogenesis and disease progression. Recently, tumors with low level (1-10%) of ER expression have been separately defined as ER Low Positive (ERlow). It is suggested that ERlow tumors might be morphologically and behaviorally different from tumors with high ER expression (ERhigh).MethodsRetrospective analysis of a prospective cohort database was performed. Patients who underwent curative surgery for early breast cancer and had available medical records were included for analysis. Difference in clinicopathological characteristics, endocrine responsiveness and five-year recurrence-free survival was evaluated between different ER subgroups (ERhigh, ERlow, and ER-negative (ER-)).ResultsA total of 2162 breast cancer patients were included in the analysis, Tis and T1 stage. Among them, 1654 (76.5%) were ERhigh, 54 (2.5%) were ERlow, and 454 (21.0%) were ER- patients. ERlow cases were associated with smaller size, higher histologic grade, positive human epidermal growth factor receptor 2 (HER2), negative progesterone receptor, and higher Ki-67 expression. Recurrence rate was highest in ER- tumors and was inversely proportional to ER expression. Recurrence-free survival was not affected by hormonal therapy in the ERlow group (P = 0.418).ConclusionERlow breast cancer showed distinct clinicopathological features. ERlow tumors seemed to have higher recurrence rates compared to ERhigh tumors, and they showed no significant benefit from hormonal therapy. Future large scale prospective studies are necessary to validate the treatment options for ERlow breast cancer.

Background In this study, we aimed to evaluate the R(un) category proposed by the International Association for the Study of Lung Cancer (IASLC) for non-small cell lung cancer (NSCLC). Methods We retrospectively reviewed the medical records of patients with NSCLC who underwent segmentectomy or lobectomy between 2014 and 2015 at our institution. Residual tumor (R) status was reclassified from the Union for International Cancer Control designation to the IASLC-proposed R classification [R0 and R(un)]. The underlying reasons for the R(un) reclassification were analyzed according to pathological stage, lymph node status, and resected lobe. A Cox proportional hazard model was used to evaluate the impacts of R(un) categorization on overall survival. Results Of 355 cases, 44.5% were reclassified as R(un). The most common reason for the reclassification was insufficient number of harvested lymph nodes or no station 7 lymph nodes. When stratified by tumor location, the absence of station 7 lymph nodes was especially prominent in both the right and left upper lung resections. In the multivariate Cox regression model, IASLC R classification was associated with poor overall survival in node-positive cases (hazard ratio: 2.657; P =.016). Conclusions Various factors resulted in reclassification to R(un) because the R(un) group was highly heterogeneous. Careful consideration is required to determine whether R(un) classification can be used as an indicator of lymph node dissection quality. For advanced cases, the R(un) definition may be useful in predicting poor prognosis.

The Surveillance, Epidemiology and End Results (SEER) and the National Cancer Database (NCDB) are databases for cancer analysis that may be subject to error in data reporting. This study examined the rates and impact of discordant data for non-small cell lung cancer.NCDB and SEER were queried for non-small cell lung cancer pathologic tumor, node, metastasis data (NCDB) or "derived" data (SEER). Discordancy between descriptors with stage and impact of outlier data were analyzed.Incomplete staging was noted in 71.5% of the NCDB and 10.3% of SEER patients. A total of 174 829 patients from the NCDB and 117 114 from SEER were analyzed. The NCDB had 97 cases with ≥20 positive lymph nodes recorded vs 27 in SEER (P.001). Mean and median sampled lymph nodes were skewed with inclusion of these data points (P .001). The NCDB misclassified 0.99% tumors5 cm as stage I vs 0.04% in SEER (P.001). The NCDB misstaged positive lymph nodes as pathologic N0 (0.59%) or stage 0 or stage I (0.65%). The NCDB misclassified pathologic N1 as lower than stage II (0.91%) or N2 as lower than stage III (0.36%). The NCDB misclassified stage I with documentation of pathologic N1 or N3 disease (0.24%) or stage II with evidence of N2 or N3 disease (0.50%). The NCDB misclassified pathologic M1 as pathologic stageIV in 0.9% of cases and misclassified 19.8% of stage IV as pathologic M0. SEER collaborative staging had no discordance (P.001).The NCDB and SEER are 2 powerful cancer databases. However, the cumulative discordancy rate was 4.9% for the NCDB and 0.008% for SEER, with more misstaging and outliers in the NCDB.

Reconstructing an esthetic interimplant papilla remains challenging with implant-supported restorations, especially for patients with a thin gingival biotype. This technique report describes a modified approach to rebuilding an interimplant papilla by joining 2 elevated connective tissue flaps at the second-stage surgery.

Our objective is to evaluate the effect of distance to facility on the use of breast conservation therapy and reconstruction for early stage breast cancer.Utilizing the National Cancer Database, we identified females, age65, with Stage I invasive ductal carcinoma from 2004 to 2015. Using logistic regression, we compared radiation, mastectomy, and reconstruction treatment patterns. A subgroup analysis was performed within the mountain region (MR).Nationwide, there are decreasing odds of radiation, increasing odds of mastectomy, and increasing odds of reconstruction. Patients living farther were less likely to receive radiation, more likely to undergo mastectomy, with no effect on reconstruction. Within the MR, patients living farther from their facility were less likely to receive radiation, more likely to undergo mastectomy, however, they were less likely to undergo reconstruction.Nationwide and within the MR, patients living farther from their facility are less likely to receive radiation and more likely to undergo mastectomy. There is a disparity between the MR and the nation in use of reconstruction for this population.

Background The role of prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) imaging in the initial staging of men with prostate cancer (PCa) has yet to be evaluated adequately. Objective To investigate the concordance of PSMA PET/CT with conventional imaging (CI) with cross-sectional abdominopelvic and/or radionuclide bone imaging in the initial staging of patients with treatment-naive PCa. Design, setting, and participants We performed a post hoc retrospective cohort study of patients enrolled in a prospective single-arm trial ( NCT03368547 ). We included patients with intermediate-risk (IR) and high-risk (HR) PCa who underwent PSMA PET/CT within 6 mo of CI. Patients with any treatment prior to PSMA PET/CT were excluded. Patient- and tumor-specific data, and imaging findings were obtained. Outcome measurements and statistical analysis Our primary outcome measurement was the concordance rate of PSMA PET/CT with CI for the identification of N, M1a, M1b, and M1c disease. Descriptive statistics were used. Results and limitations A total of 168 patients with treatment-naive IR and HR PCa met the inclusion criteria. HR disease accounted for 124/168 (73.8%) patients. The median prostate-specific antigen was 11.4 (6.8–24.6) ng/ml. The rates of nonconcordance between PSMA PET/CT and CI were 34/162 (21.0%), 5/70 (7.1%), 8/92 (8.7%), and 1/71 (1.4%) for N, M1a, M1b, and M1c disease, respectively. PSMA PET/CT assigned a higher stage in 37/168 (22.0%) patients and a lower stage in 12/170 (7.1%) patients. In a subset of 50 patients treated with radical prostatectomy and pelvic lymph node dissection, the prevalence of PSMA PET/CT–positive and that of CI-positive nodal disease were 14% and 4%, and the false negative rates were 30% and 32%, respectively. The principal limitations of this study include the heterogeneity in CI modalities and the 6-mo time frame between CI and PSMA PET. Conclusions PSMA PET/CT imaging may serve as a valuable tool in the initial staging of treatment-naive IR and HR PCa. Patient summary We evaluated how prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) compared with standard imaging (such as computed tomography, bone scan, and prostate magnetic resonance imaging) for initial staging of patients with prostate cancer. Our findings suggest that PSMA PET/CT may detect and rule out more metastatic lesions, which could prove valuable in guiding treatment.

Avulsion of a tooth is the total displacement of the tooth out of its socket. It is one of the most serious dental injuries, and replantation is the treatment of choice. Phocomelia is a rare congenital anomaly in which the proximal part of the limb is absent or markedly hypoplastic, with normal or nearly normal hand or foot. A 12-year-old male child reported to the department of Pedodontics with a chief complaint of trauma due to a road traffic accident three hours back. On examination, the patient had underdeveloped both upper limbs, there was avulsion of the maxillary anterior teeth (12, 11, 21), and dentoalveolar fracture in the maxillary anterior region. The patient was also diagnosed as having bilateral congenital distal phocomelia of the upper limbs. Replantation followed by apexification of the avulsed teeth was performed.

Purpose:To report on two cases with paraneoplastic acute exudative polymorphous vitelliform maculopathy within one month after the initiation of nivolumab. Methods:Case report. Results:Two patients with metastatic mucosal melanoma were diagnosed with acute exudative polymorphous vitelliform maculopathy within one month after the initiation of the checkpoint inhibitor nivolumab. Both cases showed a neurosensory retinal detachment and subretinal hyperautofluorescent material, which persisted after discontinuation of nivolumab and treatment with local and/or systemic corticosteroids. In one case, nivolumab was introduced again in a later stage in combination with surgical reduction of the tumor, eventually leading to resolution of the subretinal lipofuscin-rich fluid.Conclusion:The development of paraneoplastic acute exudative polymorphous vitelliform maculopathy in melanoma patients can be triggered by treatment with nivolumab. However, achieving tumor control, which may involve continuation of nivolumab, could be the key to success.

Context Staging, restaging, and surveillance of urothelial carcinoma (UC) is challenging due to suboptimal accuracy of standard of care imaging modalities. Prostate-specific membrane antigen (PSMA) imaging may serve to improve characterisation of UC. Objective To appraise available literature regarding cellular, imaging, and prognostic implications of PSMA for UC. Evidence acquisition A systematic review was performed considering all available literature (including conference abstracts) published from 1990 to 2020 and reported according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines following registration in PROSPERO (CRD42020186744). All relevant texts relating to immunohistochemical analysis and PSMA-based imaging in UC were included and collated. Additionally, FOLH1 (gene encoding PSMA) expression according to The Cancer Genome Atlas (TCGA) database was analysed as well as according to consensus and TCGA molecular classification subtypes and subsequently compared with clinical outcomes. Evidence synthesis PSMA expression across UC tumour tissue was heterogeneous (0–100%) but appeared to decrease with increased grade and stage. The TCGA analysis demonstrated loss of FOLH1 expression with increasing T stage (p = 0.0180) and N stage (p = 0.0269), and reduced FOLH1 expression was associated with worse disease-free survival. PSMA expression in UC neovasculature was variable but mostly increased (44–100%). Eleven reports of PSMA-based imaging for UC were identified, reporting on 18 patients. PSMA positron emission tomography (PET) imaging was positive in 17 out of 18 patients. The included literature review data were limited by mostly low-quality, retrospective studies. Conclusions Tissue PSMA, or FOLH1 expression, may inversely be associated with pathological and survival outcomes in localised UC. PSMA PET imaging may improve detection of metastatic disease and response to systemic therapy due to PSMA expression in neovasculature. Available evidence is limited; thus, larger, prospective studies are required to confirm early results and define populations that benefit most. Patient summary In this systematic review, we assess the potential role of prostate-specific membrane antigen in urothelial cancer. We found that its utility is in expression of blood vessels surrounding metastasis. We conclude that it may be beneficial in detecting metastasis and response to systemic therapies.

Seat belt breast deformity can result in significant aesthetic, functional and psychosocial sequelae. Although seat belt breast deformity is well documented, there is a lack of literature describing their reconstructive management. We describe the surgical management of a 63-year-old woman presenting with stage 2b seat belt breast deformity, who underwent scar revision, repositioning of the nipple–areola complex and contralateral breast reduction using Wise-pattern incisions based on superior pedicles. She made an excellent recovery with an improved aesthetic result.

A 70-year-old man was referred to the pulmonary office for evaluation of a solitary lung nodule in September 2019. The patient was diagnosed with stage 1 adenocarcinoma of the rectum in November 2018 and underwent low anterior resection without any complications. No chemotherapy or radiation therapy

BackgroundRenal cell carcinoma (RCC) comprises of a spectrum of clinico-pathologically distinct entities thereby making it difficult to accurately predict the clinical outcome. Though many predictive factors have been described in literature, tumor stage and nuclear grade have been established to consistently correlate with the tumor behaviour. However, tumors in the same stage have shown to behave differently. Similarly subjectivity and lack of reproducibility in nuclear grade mandates use of more objective parameters such as digital nuclear morphometry which could provide consistent and more reliable results in predicting prognosis. The study was conducted with the main objective of comparing the histological grade and the nuclear morphometric variables in RCC for predicting the clinical outcome.Material and methodsA total of 219 cases of renal tumors in adults were retrieved retrospectively from the archives of pathology department in Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow and their clinical, gross and microscopic features were noted. Nuclear grading was done in 181 cases of clear cell and papillary RCC of which computer-assisted morphometry for various nuclear parameters was done in 100 cases where a follow-up data of at least 3 years was available. Nuclear grade and morphometric parameters were correlated statistically with the clinical outcome of the patients.ResultsHistological nuclear grade did not show statistically significant correlation with progression free survival (PFS). Higher values of mean nuclear area, mean nuclear circumference, mean nuclear major diameter and mean nuclear minor diameter were significant predictors of PFS with a strong inverse correlation.ConclusionNuclear morphometry is a more reliable predictor of clinical outcome in patients of RCC when compared to histological grade and should be included in predictive model with other clinical and pathological parameters to accurately determine tumor behaviour.

Background: Lipedema is a distinct adipose disorder from obesity necessitating awareness as well as different management approaches to address pain and optimize quality of life (QoL). The purpose of this proof-of-principle study is to evaluate the therapeutic potential of physical therapy interventions in women with lipedema. Methods and Results: Participants with Stage 1-2 lipedema and early Stage 0-1 lymphedema (n = 5, age = 38.4 ± 13.4 years, body mass index = 27.2 ± 4.3 kg/m2) underwent nine visits of physical therapy in 6 weeks for management of symptoms impacting functional mobility and QoL. Pre- and post-therapy, participants were scanned with 3 Tesla sodium and water magnetic resonance imaging (MRI), underwent biophysical measurements, and completed questionnaires measuring function and QoL (patient-specific functional scale, PSFS, and RAND-36). Pain was measured at each visit using the 0-10 visual analog scale (VAS). Treatment effect was calculated for all study variables. The primary symptomatology measures of pain and function revealed clinically significant post-treatment improvements and large treatment effects (Cohen's d for pain VAS = -2.5 and PSFS = 4.4). The primary sodium MRI measures, leg skin sodium, and subcutaneous adipose tissue (SAT) sodium, reduced following treatment and revealed large treatment effects (Cohen's d for skin sodium = -1.2 and SAT sodium = -0.9). Conclusions: This proof-of-principle study provides support that persons with lipedema can benefit from physical therapy to manage characteristic symptoms of leg pain and improve QoL. Objective MRI measurement of reduced tissue sodium in the skin and SAT regions indicates reduced inflammation in the treated limbs. Further research is warranted to optimize the conservative therapy approach in lipedema, a condition for which curative and disease-modifying treatments are unavailable.

Exact lymph node staging is essential in rectal cancer therapy.The aim of the study was to assess the impact of intra-arterial indigo carmine injection after transanal total mesorectal excision on the number of retrieved lymph nodes.This was a retrospective, nonrandomized study.The study was conducted at a tertiary hospital by a multidisciplinary team.Patients who underwent transanal total mesorectal excision for suspected rectal cancer between 2013 and 2019 were included.Rectal cancer specimens received ex vivo intra-arterial indigo carmine injection to stain lymph nodes.Outcome measures included the number of retrieved lymph nodes with or without staining.Specimens of 189 patients were analyzed, of which 108 (57.1%) were stained with indigo carmine. A mean of 19.8 ± 6.1 lymph nodes was identified in stained samples compared to 16.0 ± 4.9 without staining ( p0.001). Multivariable analysis showed that 3.2 additional lymph nodes were found in stained specimens (95% CI: 1.0 to 5.3; p = 0.02). In stained specimens the adequate lymph node count (≥12) was increased in univariable (odds ratio: 3.24, 95% CI: 1.13 to 10.65; p = 0.03) but not in multivariable analysis. Indigo carmine injection had no effect on the number of positive lymph nodes or the nodal stage. Chemoradiotherapy reduced the lymph node count by 2.5 ( p = 0.008). After staining, 95.0% of patients with chemoradiotherapy had ≥12 lymph nodes retrieved. The median follow-up of patients was 24.2 months with a local recurrence rate of 3.3%.The study is limited by its retrospective design and the nonrandomized allocation.Ex vivo intra-arterial indigo carmine injection increases the number of isolated lymph nodes after transanal total mesorectal excision regardless of neoadjuvant chemoradiotherapy. Indigo carmine injection is not associated with nodal upstaging or an increased number of tumor-positive lymph nodes.

Se identificó una media de 19,8 ± 6,1 ganglios linfáticos en las muestras teñidas en comparación con 16,0 ± 4,9 sin tinción ( p0,001). El análisis multivariado mostró que se encontraron 3.2 ganglios linfáticos adicionales en las muestras teñidas (intervalo de confianza del 95%: 1,0 a 5,3; p = 0,02). En las muestras teñidas, el recuento adecuado de ganglios linfáticos (≥12) aumentó en el análisis univariado (razón de posibilidades: 3,24, intervalo de confianza del 95%: 1,13 a 10,65; p = 0,03) pero no en el multivariado. La inyección de índigo carmín no tuvo ningún efecto sobre el número de ganglios linfáticos positivos o el estadio ganglionar. La quimiorradioterapia redujo el recuento de ganglios linfáticos en 2,5 ( p = 0,008). Después de la tinción, en el 95,0% de los pacientes con quimiorradioterapia se recuperaron ≥12 ganglios linfáticos. La mediana de seguimiento de los pacientes fue de 24,2 meses con una tasa de recurrencia local del 3,3%.LIMITACIONES:El estudio está limitado por su diseño retrospectivo y la asignación no aleatoria.CONCLUSIONES:La inyección ex vivo de índigo carmín intraarterial aumenta el número de ganglios linfáticos aislados después de la escisión total del mesorrectal por vía transanal a pesar de la quimiorradioterapia neoadyuvante. La inyección de índigo carmín no se asocia con un aumento del estadio de los ganglios ni con un mayor número de ganglios linfáticos positivos para tumor.

Objective The objective of this study was to assess characteristics of patients with mandibular osteoradionecrosis (ORN) of severity necessitating segmental mandibulectomy and osteocutaneous free flap reconstruction. Study Design This study is a retrospective review of patients who underwent free flap reconstruction of the mandible at the UCLA Medical Center between January 2016 and February 2020 secondary to ORN. Results Twenty-nine charts with detailed dental and medical records were identified. Hypertension was reported in 14 of 29 patients, diabetes in 2 of 29, osteoporosis in 2 of 29, antiresorptive use in 3 of 29, tobacco use in 15 of 29, and alcohol use in 19 of 29. Twenty-three patients initially had stage III-IV cancer. The median radiation dose was 68 Gy and median time to ORN was 5.2 years. Chemotherapy was given in 21 patients and 4 had previous mandibular surgery. Twelve of 29 patients had surgical procedures identified as the causative factor and 17 of 29 occurred spontaneously. Median decayed, missing, and filled teeth score was 17 and 17 of 29 patients had grade II-IV periodontitis. Periodontitis was present in 8 of 17 of spontaneous and 1 of 12 of surgery cases. Twenty-five of 29 cases occurred in the same oral sextant as the tumor. Conclusion Severe ORN occurred at doses >60 Gy in most cases. Location of the primary tumor was predictive of site of ORN and only molars were involved when precipitated by tooth extraction. Risk of ORN persists indefinitely.

This study investigated a 2-stage arterial switch operation (ASO) to treat transposition of the great arteries (TGA) with intact ventricular septum (TGA-IVS) in late referral patients.We retrospectively analyzed patients with TGA-IVS or TGA with restricted ventricular septal defects who had undergone 2-stage ASO at our institution from February 2007 to August 2018. Included were 41 patients: 21 (51.2%) who had undergone long-term 2-stage ASO and 20 (48.8%) who had undergone rapid 2-stage ASO.The long-term 2-stage group was older at ASO (3.5 vs 25 months; P.001). Results were more satisfactory in the long-term group than in the rapid group for intensive care unit time (P = .004), mechanical ventilation time (P = .004), and length of stay (P = .007). No in-hospital death occurred in the long-term group, and the postoperative course was more manageable in the long-term group than in the rapid group. However, the risk of significant neoaortic regurgitation was lower in the rapid group, which also had a better left ventricular ejection fraction.The long-term group achieved better early-term outcomes than the rapid group. However, a high risk of neoaortic regurgitation and myocardial dysfunction was also noted.

Oral cancer is one of the most prevalent malignancy affecting oral cavity. Determining the correct type of oral cancer at the early stages is important in designing a detailed treatment plan and predicting the response of the patient to the treatment being adopted. A major challenge lies in the detection of oral cancer from histopathological images. In oral malignancy diagnosis, the main visual features are generally extracted from the architectural differences of epithelial layers and the appearance of keratin pearls. This paper proposes a new approach for classifying oral cancer using a deep learning technique known as capsule network. Dynamic routing and routing by agreement of capsule network makes it more robust for rotation and affine transformation of augmented oral dataset. This network’s capability of handling pose, view and orientation makes it suitable for analysis of oral cancer histopathological images at an early stage. The performance of cross-validation indicate that the proposed methodology can efficiently classify the histopathological images of Oral Squamous Cell Carcinoma (OSCC) with 97.78% sensitivity, 96.92% specificity and 97.35% accuracy.

Factors contributing to the use of preoperative MRI remain poorly understood.Data from a randomized controlled trial of stage 0-3 breast cancer patients undergoing breast conserving surgery between 2016 and 2018 were analyzed.Of the 396 patients in this trial, 32.6% had a preoperative MRI. Patient age, race, ethnicity, tumor histology, and use of neoadjuvant therapy were significant predictors of MRI use. On multivariate analysis, younger patients with invasive lobular tumors were more likely to have a preoperative MRI. Rates also varied significantly by individual surgeon (p 0.001); in particular, female surgeons (39.9% vs. 24.0% for male surgeons, p = 0.001) and those in community practice (58.9% vs. 14.2% for academic, p 0.001) were more likely to order preoperative MRI. Rates declined over the two years of the study, particularly among female surgeons.Preoperative MRI varies with patient age and tumor histology; however, there remains variability by individual surgeon.

INTRODUCTION AND AIM Helicobacter pylori (H. pylori) is known to be capable of causing chronic inflammation of the gastric mucosa that slowly progresses through the premalignant stages, reaching localized gastric adenocarcinoma (GAC). Its outcome is closely related to the stage at which diagnosis is made. The aim of the present study was to determine cost-benefit by comparing esophagogastroduodenoscopy, serum pepsinogen detection, and no screening at all. MATERIAL AND METHODS Utilizing Markov chains and Monte Carlo simulation, the costs and effects of various detection modalities were simulated to analyze the cost-benefit of each strategy. For our population, we used the published data of patients with gastric cancer, applicable to the Mexican population. RESULTS The results were reported as incremental cost-effectiveness ratios. The best strategy was serum pepsinogen determination, followed by the strategy of endoscopic examination with continued monitoring every 3 years. CONCLUSIONS The performance of serum pepsinogen serology and directed endoscopic examination (and continued monitoring, if necessary) for GAC screening could be a cost-effective intervention in Mexico, despite the low-to-moderate general prevalence of the disease.

Background: Heart failure (HF) due to myocarditis might not respond in the same way to standard therapy as HF due to other aetiologies. The aim of this study was to investigate the value of endomyocardial biopsies (EMB) for clinical decision-making and its relation to the outcome of paediatric patients with myocarditis. Methods: Clinical and EMB data of children with myocarditis collected for the MYKKE-registry between 2013 and 2020 from 23 centres were analysed. EMB studies included histology, immunohistology, and molecular pathology. The occurrence of major adverse cardiac events (MACE) including mechanical circulatory support (MCS), heart transplantation, and/or death was defined as a combined endpoint. Results: Myocarditis was diagnosed in 209/260 patients: 64% healing/chronic lymphocytic myocarditis, 23% acute lymphocytic myocarditis (AM), 14% healed myocarditis, no giant cell myocarditis. The median age was 12.8 (1.4-15.9) years. Time from symptom-onset to EMB was 11.0 (4.0-29.0) days. Children with AM and high amounts of mononuclear cell infiltrates were significantly younger with signs of HF compared to those with healing/chronic or healed myocarditis. Myocardial viral DNA/RNA detection had no significant effect on outcome. The worst event-free survival was seen in patients with healing/chronic myocarditis (24%), followed by acute (31%) and healed myocarditis (58%, p=0.294). A weaning rate of 64% from MCS was found in AM. Conclusions: EMB provides important information on the type and stage of myocardial inflammation and supports further decision-making. Children with fulminant clinical presentation, high amounts of mononuclear cell infiltrates or healing/chronic inflammation and young age have the highest risk for MACE.

Introduction: There is an ongoing need to identify various pathological factors that can predict various survival parameters in patients with upper tract urothelial carcinoma (UTUC). With this review, we aim to scrutinize the impact of several pathological factors on recurrence free survival (RFS), cancer-specific survival (CSS) and overall survival (OS) in patients with UTUC. Materials and Methods: Systematic electronic literature search of various databases was conducted for this review. Studies providing multivariate hazard ratios (HR) for various pathological factors such as tumor margin, necrosis, stage, grade, location, architecture, lymph node status, lymphovascular invasion (LVI), carcinoma in situ (CIS), multifocality and variant histology as predictor of survival parameters were included and pooled analysis of HR was performed. Results: In this review, 63 studies with 35.714 patients were included. For RFS, all except tumor location (HR 0.94, p=0.60) and necrosis (HR 1.00, p=0.98) were associated with worst survival. All the pathological variables except tumor location (HR 0.95, p=0.66) were associated with worst CSS. For OS, only presence of CIS (HR 1.03, p=0.73) and tumor location (HR 1.05, p=0.74) were not predictor of survival. Conclusions: We noted tumor grade, stage, presence of LVI, lymph node metastasis, hydronephrosis, variant histology, sessile architecture, margin positivity and multifocality were associated with poor RFS, CSS and OS. Presence of CIS was associated with poor RFS and CSS but not OS. Tumor necrosis was associated with worst CSS and OS but not RFS. Tumor location was not a predictor of any of the survival parameters.

Background Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH syndrome), as congenital anomaly of female reproductive tract, is characterized by the congenital absence of uterus and vagina. Dilation maneuver was recommended as the non-surgical treatment for these patients. However, only several cases were reported depicting the prolapse of dilated neovagina of MRKH syndrome patients. Case We report our own experiences in treating 2 neovaginal prolapse MRKH syndrome patients receiving ischial spinous fascia fixation (ISFF) and reviewed neovaginal prolapse occurrence in MRKH syndrome. In approach to evaluate anatomic and functional outcome after operation, we compared the prolapse stage with POP-Q score and analyzed sexual activities by standardized Female Sexual Function Index 1 (FSFI) and Modified Body Image Scale 2 (MBIS). Summary and Conclusion Both subjective and objective improvement were observed in these two patients.

Background We present here a case series of patients who underwent resection for Masaoka Stage III and IVa Thymic Epithelial Tumors (TETs) with invasion into the superior vena cava. Methods 29 patients with Stage III and IVa TETs were treated surgically in three institutions. Operative resections involved replacing the superior vena cava from one of the innominate veins (n=18) or via reconstruction by truncal replacement (n=2) or patchplasty (n=9). Results Fifteen patients underwent neoadjuvant treatment. Thirty and 90-day mortality rate were 3.4% and 10.3%, respectively. For Stage III patients, the median overall survival and DFS were 39 and 30 months, respectively. The median overall survival and DFS in patients with Masaoka Stage IVa disease were 67 and 21 months, respectively. Undergoing only preoperative chemotherapy (p=0.007) or receiving no chemotherapy (p=0.009) had a disease-free survival that was significantly higher than receiving both pre- and postoperative chemotherapy. Conclusions SVC resection and reconstruction in Masoaka Stage III and IVa TETs can be performed with acceptable morbidity and mortality. Stage IVa patients with SVC involvement can be treated with similar results as Stage III patients with multimodality treatment.

Medication-related osteonecrosis of the jaw (MRONJ) is a drug adverse reaction. Seven osteonecrosis areas in 5 cases were treated with stage-2 MRONJ using human amniotic membrane (HAM) transplantation after sequestrectomy. Patients were evaluated in terms of infection (pain, erythema, and pus), mucosal coverage, and pain at 1, 2, 4, 8, and 12 weeks. Patients who showed improvement (total mucosal coverage, no sign of infection and pain) at the end of 12 weeks were followed up every 8 weeks. Also, radiographic examinations (panoramic radiography at every 8 weeks, cone-beam computed tomography at every 6 months) were performed to evaluate bone destruction. Complete mucosal closure was achieved in 6 necrosis sites. In only 1 patient, mucosal coverage was not achieved. No pain and infection relapse were observed during the follow-ups. HAM might be an effective material in terms of soft tissue healing and elimination of pain and infection for stage-2 MRONJ. Clinical Trials Registration Number: NCT04967963

Small bowel cancers are rare gastrointestinal malignancies and tumor location impact on outcomes is unclear.A retrospective review was performed on stage I to IV small bowel cancer cases from 2000 to 2017 in British Columbia, Canada. Baseline patient characteristics, disease-free survival (DFS) and overall survival (OS) were evaluated by tumor location and systemic therapy use patterns were summarized.Of 340 patients included, primary tumor distribution was: duodenum (51.2%), ileum (19.1%), jejunum (18.5%), and unspecified (11.2%). Median DFS for stage I to III disease was 37.7, 49.1, and 26.7 months for duodenal, jejunal, and ileal tumors (P = .018). Median OS was 9.6, 35.2, and 20.1 months for duodenal, jejunal, and ileal tumors (P.0001). Compared to duodenal primaries, both jejunal and ileal tumors were associated with significantly improved OS (HR 0.43, P.001 for jejunal; HR 0.71, P = .035 for ileal). Adjuvant therapy was given to 21.6% of stage II and 50.6% of stage III cancers. Among patients with metastatic disease, median OS was 4.2, 11.4, and 6.9 months for duodenal, jejunal, and ileal tumors (P = .0019). Jejunal tumors had the best prognosis (HR 0.48, P = .001 vs. duodenum).Survival differences exist when small bowel cancers were assessed by tumor location, and jejunal tumors portended better prognosis overall.

Purpose: To discuss the status and progress of treatment of lower limb lymphedema (LLL) after gynecological cancer treatment. Common gynecological malignancies include endometrial cancer, cervical cancer, ovarian cancer, and vulvar cancer. LLL is one of the common complications after gynecological cancer treatment. LLL is one of the common complications after gynecological cancer treatment, which seriously affects patients' quality of life. Methods: We searched the Medline database for literature on LLL after gynecological oncology treatment, reviewed the incidence and risk factors for LLL in different gynecological malignancies, and summarized advances in the prevention and treatment of LLL after gynecological malignancy treatment. Finally, we review data-based approaches for the treatment of LLL and discuss experimental therapies currently in development. Results: Treatment of LLL is usually combined, conservative, and surgical. Complete decongestive therapy is the gold standard for the treatment of LLL. Prevention and treatment of lymphedema of the lower extremities are important for patients with gynecological cancers. Conclusion: Clinicians should be aware of the prevention and treatment of LLL, with a precise diagnosis and effective intervention at an early stage to delay its progression and improve patients' quality of life.

We report a summary of developmental work to explore, develop and establish clinical applications of real-time magnetic resonance imaging (rtMRI) with a temporal resolution of 70 frames per second in oral and maxillofacial surgery. rtMRI can contribute to procedure planning, diagnostics, rehabilitation, monitoring and patient education. At present, conventional MRI is used extensively in diagnosis, staging and follow-up of head and neck cancer patients, with scanning durations of typically several minutes and a temporal resolution of up to 0.5 frames per second. The potential for rtMRI, where function can be assessed could go far beyond the established clinical application of conventional MRI. Preliminary prototyping is a first stage in the establishment of rtMRI in oral and maxillofacial surgery. We follow best-practice approaches in co-creation across multiple disciplines, an indispensable aspect in the development of new methodologies and diagnostic tools.

Objective Dementia with Lewy bodies (DLB) is the second-most common form of neurodegenerative dementia after Alzheimer's disease (AD). Falls are a vital prognostic factor in patients with dementia and are a characteristic feature of DLB. This study investigated the screening potential of the fall risk evaluation for DLB and compared it with that of AD to facilitate an accurate diagnosis. Methods We enrolled patients diagnosed with DLB (n = 410) and AD (n = 2,683) and categorized the participants into 3 groups depending on their physical ability, age, cognitive function, and fall events. Using the Fall Risk Index-21 (FRI-21) questionnaire, we evaluated and comparatively analyzed the fall risk between DLB and AD patients in three defined groups of participants. Results The FRI-21 score was significantly higher in DLB patients than in AD patients in every group. Using this score, we were able to distinguish between DLB and AD patients in each group. Among the three groups, the group with a young age, relatively mild cognitive dysfunction, and no fall events exhibited the best specificity for DLB (0.895). Conclusions The FRI-21 is a useful tool for screening for DLB and differentiating it from AD. This questionnaire can be used at a relatively early stage of the disease in young patients with mild cognitive dysfunction and no history of falling. These preliminary results need to be validated in an interventional study to evaluate the effectiveness of rehabilitative measures and daily environmental changes carried out to prevent falls using this tool.

Background Mycosis fungoides with large-cell transformation (MF-LCT) is associated with an aggressive clinical course, yet data comparing treatment outcomes in MF-LCT are sparse. Objective To compare treatment outcomes and to determine disease prevalence and characteristics associated with survival in MF-LCT. Methods A retrospective review was conducted of mycosis fungoides patients from 2012 to 2020 treated at Thomas Jefferson University. Patients with histopathologic diagnosis of MF-LCT were included. Treatment outcomes were assessed by mean changes in the modified Severity Weighted Assessment Tool (mSWAT) and stage. Results Of 171 patients with mycosis fungoides, 23 (13.4%) had histologic diagnosis of MF-LCT. The overall 5-year survival rate for MF-LCT was 74% and was not significantly associated with sex, age, or initial stage at the time of MF-LCT diagnosis. Brentuximab vedotin showed the greatest mean decrease in mSWAT (−20.53) and stage progression (change in Δ stage: –0.4) in MF-LCT compared to oral bexarotene (ΔmSWAT: +4.51; Δstage: +0.27), skin-directed therapy (ΔmSWAT: −5.93; Δstage: −0.08), and chemotherapy (ΔmSWAT: +4.97; Δstage: +0.85). Limitations Single-center retrospective design, and patients often on multiple treatment modalities. Conclusions We report superior treatment outcomes for brentuximab vedotin compared to oral bexarotene, skin-directed therapy, and chemotherapy in MF-LCT in both early and advanced disease.

Aims To analyse the disease-free survival and overall survival in older adults with breast cancer after breast-conserving therapy, focusing on the relevance of non-breast malignancy (NBM) with respect to survival rates. Materials and methods Analyses were based on 1205 women aged 65 years and older with breast cancer treated with breast-conserving therapy between 1999 and 2015. Patients were divided into three age categories: 65–70, 71–75 and >75 years. Multivariate survival analysis was carried out using Cox regression analysis. Results The two youngest age categories showed excellent results, with a 12-year disease-free survival of 84.6 and 86.3%, respectively. We noted a 17.2% incidence of NBM, particularly for colon cancer and lung cancer. Most (72.9%) occurred after a diagnosis of breast cancer. Of those 72.9%, about 50% died as a result of NBM within 2 years of the diagnosis of NBM. The overall 12-year NBM-specific survival was 92.0%. The 12-year overall survival was 60.0% for all and for the three abovementioned age categories was 73.3, 54.4 and 28.4%, respectively. The cause of death for all was predominantly non-malignancy-related morbidity. Conclusion The impact of breast cancer on life expectancy was limited, in particularly for women aged 65–75 years. The relevance of NBM on survival was limited.

ZusammenfassungAtypische Infektionen an der Hand treten selten auf und werden deshalb häufig fehlinterpretiert. Erfolgt die korrekte Therapie erst verspätet, können irreversible Schäden entstehen, schlimmstenfalls kann es zu lebensgefährlichen septischen Verläufen kommen. Der Artikel soll eine Übersicht über einige der häufigsten atypischen Infektionen und deren Erscheinungsbild an der Hand (Mykobakterien, Vibrionen, Francisella, Aktinomyceten) geben und diese mit 2 Fallberichten illustrieren. Das Wissen um die Pathogenese der häufigsten atypischen Infektionen erleichtert es, diese differenzialdiagnostisch im Alltag zu berücksichtigen, spezielle diagnostische Schritte einzuleiten und eine adäquate Therapie frühzeitig durchzuführen.

The prognostic significance of an architectural grading system for clear cell renal cell carcinoma (ccRCC) has recently been demonstrated. The present study aimed to establish a vascularity-based architectural classification using the cohort of 436 patients with localized ccRCC who underwent extirpative surgery and correlated the findings with conventional pathologic factors, gene expression, and prognosis. First, we assessed architectural patterns in the highest-grade area on hematoxylin and eosin-stained slides, then separately evaluated our surrogate score for vascularity. We grouped nine architectural patterns into three categories based on the vascular network score. "Vascularity-based architectural classification" was defined: category 1: characterized by enrichment of the vascular network, including compact/small nested, macrocyst/microcystic, and tubular/acinar patterns; category 2: characterized by a widely spaced-out vascular network, including alveolar/large nested, thick trabecular/insular, papillary/pseudopapillary patterns; category 3: characterized by scattered vascularity without a vascular network, including solid sheets, rhabdoid and sarcomatoid patterns. Adverse pathological prognostic factors such as TNM stage, WHO/ISUP grade, and necrosis were significantly associated with category 3, followed by category 2 (all p < 0.001). We successfully validated the classification using The Cancer Genome Atlas (TCGA) cohort (n = 162), and RNA-sequencing data available from TCGA showed that the angiogenesis gene signature was significantly enriched in category 1 compared to categories 2 and 3, whereas the immune gene signature was significantly enriched in category 3 compared to categories 1 and 2. In univariate analysis, vascularity-based architectural classification showed the best accuracy in pathological prognostic factors for predicting recurrence-free survival (c-index = 0.786). The predictive accuracy of our model which integrated WHO/ISUP grade, necrosis, TNM stage, and vascularity-based architectural classification was greater than conventional risk models (c-index = 0.871 vs. 0.755-0.843). Our findings suggest that the vascularity-based architectural classification is prognostically useful and may help stratify patients appropriately for management based on their likelihood of post-surgical recurrence.

Background Data regarding Asian patients with mycosis fungoides (MF) are limited. Objective We aimed to investigate the clinical profile and long-term outcomes of patients with MF in Korea. Methods A retrospective review of 223 patients with MF who were followed up for more than 6 months or died of MF within 6 months of diagnosis was performed. Results Approximately 96.4% and 3.6% of the patients had an early stage and advanced stage, respectively. The mean age at diagnosis was 44.8 years. The mean duration of symptoms before diagnosis was 47.0 months. Various subtypes were noted, including mycosis fungoides palmaris et plantaris (21.5%), folliculotropic (8.5%), pityriasis lichenoides-like (6.7%), ichthyosiform (4.0%), lichenoid purpura-like (2.7%), and hypopigmented (2.2%) MF. Juvenile patients accounted for 16.6%. The higher the skin T stage, the poorer the response to treatment. The 10-year overall survival was 96.8% in early-stage patients and 25.0% in advanced-stage patients. General prognosis was favorable, while recurrence and subtype switching were seen in 29.4% and 2.7% of patients, respectively. Limitations Our patients may not represent all Korean patients with MF. Conclusion MF in Korea has a high proportion of variants, a younger age at onset, and favorable prognosis. A high index of suspicion and skin biopsy are needed for early diagnosis.

Background Personalized treatment for clinical T1 renal cortical masses (RCMs) should take into account competing risks related to tumor and patient characteristics. Objective To develop treatment-specific prediction models for cancer-specific mortality (CSM), other-cause mortality (OCM), and 90-d Clavien grade ≥3 complications across radical nephrectomy (RN), partial nephrectomy (PN), thermal ablation (TA), and active surveillance (AS). Design, setting, and participants Pretreatment clinical and radiological features were collected for consecutive adult patients treated with initial RN, PN, TA, or AS for RCMs at four high-volume referral centers (2000–2019). Outcome measurements and statistical analysis Prediction models used competing-risks regression for CSM and OCM and logistic regression for 90-d Clavien grade ≥3 complications. Performance was assessed using bootstrap validation. Results and limitations The cohort comprised 5300 patients treated with RN (n = 1277), PN (n = 2967), TA (n = 476), or AS (n = 580). Over median follow-up of 5.2 yr (interquartile range 2.5–8.7), there were 117 CSM, 607 OCM, and 198 complication events. The C index for the predictive models was 0.80 for CSM, 0.77 for OCM, and 0.64 for complications. Predictions from the fitted models are provided in an online calculator ( https://small-renal-mass-risk-calculator.fredhutch.org ). To illustrate, a hypothetical 74-yr-old male with a 4.5-cm RCM, body mass index of 32 kg/m2, estimated glomerular filtration rate of 50 ml/min, Eastern Cooperative Oncology Group performance status of 3, and Charlson comorbidity index of 3 has predicted 5-yr CSM of 2.9–5.6% across treatments, but 5-yr OCM of 29% and risk of 90-d Clavien grade 3–5 complications of 1.9% for RN, 5.8% for PN, and 3.6% for TA. Limitations include selection bias, heterogeneity in practice across treatment sites and the study time period, and lack of control for surgeon/hospital volume. Conclusions We present a risk calculator incorporating pretreatment features to estimate treatment-specific competing risks of mortality and complications for use during shared decision-making and personalized treatment selection for RCMs. Patient summary We present a risk calculator that generates personalized estimates of the risks of death from cancer or other causes and of complications for surgical, ablation, and surveillance treatment options for patients with stage 1 kidney tumors.

Cervical Spondylosis (CS) is a chronic spinal condition in which the spine gradually stiffens and can finally become completely inflexible. It is arduous to diagnose in early stages and leads to delay in medication. The risk level of Cervical Spondylosis can be reduced if it is detected in primary care. Based on this objective, a system is designed and developed to diagnose and predict the severity of cervical spondylosis in early stages. Different machine learning techniques are evaluated for this and results indicate that machine learning techniques can provide a low cost and accurate mechanism for early stage spondylosis detection.

A 71-year-old male presented with Merkel cell carcinoma along with inguinal lymph node involvement (stage III). The patient was proposed for systemic treatment followed by inguinal lymphadenectomy and adjuvant radiotherapy. During the follow-up period, recurrences were documented (lymphatic and visceral) and were treated with salvage surgery and radiotherapy. On the fifth year of follow-up the patient was diagnosed with a metastasis in the right seminal vesicle and underwent stereotactic body radiation therapy. Two-years later, tumor recurrence in the right seminal vesicle was managed with salvage robotic assisted seminal vesiculectomy. Advanced stages of Merkel cell carcinoma have a poor outcome and salvage treatments should be tailored to each patient. A multidisciplinary approach was crucial in achieving successful outcomes. The patient is still recurrence free twenty-four months after surgery. To the best of our knowledge, this is the first publication reporting a seminal vesical Merkel cell metastasis.Doente do sexo masculino de 71 anos, com carcinoma de células de Merkel com metastização ganglionar inguinal (estádio III), submetido a terapêutica sistémica seguida de linfadenectomia inguinal e radioterapia adjuvante. Durante o seguimento, todas as recorrências foram tratadas com radioterapia ou cirurgia de salvação. Cinco anos após o diagnóstico inicial, o doente foi diagnosticado com uma metástase na vesicula seminal direita, tendo sido tratado com radioterapia estereotáxica corporal. Dois anos mais tarde, por nova recorrência do tumor na vesicula seminal direita, foi submetido a uma vesiculectomia seminal robótica de salvação. Estádios avançados do carcinoma de células de Merkel apresentam um prognóstico reservado e os tratamentos de salvação devem ser adaptados a cada doente. Uma abordagem multidisciplinar revelou-se crucial para o sucesso do caso. O doente encontra-se no vigésimo quarto mês de pós-operatório, sem evidência de recidiva de doença. Até à data, este é o primeiro caso descrito de metástase na vesicula seminal de carcinoma de células de Merkel.
