Concurrent chemoradiotherapy (CCRT) has been the standard of care for locally advanced diseases regardless of human papillomavirus infection status. Other treatment options include surgery followed by adjuvant therapy and induction chemotherapy followed by CCRT or radiotherapy. However, for locally advanced T4 laryngeal or hypopharyngeal diseases, surgery is preferred over CCRT. Given the improvement in the functional outcomes of surgery, examining the oncologic outcomes in OPSCC patients is critical. This study aimed to determine whether differences in overall survival (OS) exist between surgery and CCRT. Oropharyngeal cancer patients included in the cancer registry of our hospital from January 2014 to December 2018 were retrospectively analyzed. Patients with T4 disease who underwent curative treatment were identified. In this study, the primary and secondary outcomes were OS and disease-free survival (DFS), respectively. Potential confounding factors were also evaluated. Details regarding recurrence pattern were listed. From 2014 to 2018, 74 newly diagnosed oropharyngeal cancer patients were identified from our cancer registry database, 60 of whom satisfied our inclusion criteria. Our findings showed an OS of 25.5 months and DFS of 17.5 months. No significant difference in both of OS and DFS were observed between the surgery and CCRT cohorts. Sex, stage, second primary cancer, IC, and primary treatment were not correlated with DFS. Male sex was the only significant factor identified, with an HR of 0.2 for OS (95% confidence interval, 0.06-0.71). No significant difference in both OS and DFS were observed between the CCRT and surgery cohorts. CCRT remains the standard of care for locally advanced disease.

Background: Hounsfield units (HU) values derived from computerized tomography (CT) have been used in the diagnosis of osteoporosis in the lumbar spine. Objective: This study aimed to identify anatomical dimensions of lumbar vertebrae on CT images, which were different between older normal, osteopenic, and osteoporotic subjects. Methods: This prospective pilot study enrolled 79 older adults. Based on CT measurements of lumbar vertebrae in HU, participants were classified into three groups: normal (HU > 109), osteopenia (HU: 94-108), and osteoporosis (HU < 93). Altogether, 42 anatomical variables of lumbar vertebrae, L2, L3, L4, and L5, were measured in each participant by CT, including 24 parameters measurable by MRI or plain X-ray and 18 parameters measurable by MRI only. Results: Among the morphological measurements also measurable by MRI and plain X-ray, the length upper curve, 50% and 75% of L5, length upper with the cortex of L4, length center of the cortex of L3, as well as width upper curve 75% of L2, were significantly different between the three groups (p= 0.008, 0.007, 0.035, 0.036, and 0.003 respectively). Among the morphological measurements also measurable by MRI, only the width upper cortex 75% of L5 and the width lower cortex 25% of L3, were significantly different between the three groups (p= 0.031 and 0.020, respectively). Conclusion: Seven CT morphological measurements may be used as “reference standard” CT measurements for preliminarily diagnosing osteoporosis and osteopenia in older adults.

Highlights • The occurrence of rectal annular constriction due to infiltration by bladder cancer is relatively rare, and difficult diagnosis by colonoscopy. • The images including computed tomography, colonoscopy, and magnetic resonance imaging was fully recorded in our report. • The poor prognosis was noted from literature review with no record for survival >2 years after diagnosis of a rectal lesion., Introduction Bladder urothelial carcinoma rarely spreads to the gastrointestinal tract, and its presentation in the rectum varies. We report a case of a patient who presented with an annular constriction of the rectum. Presentation of case A 60-year-old man was referred to our hospital with chief complaints of anal stricture and partial obstruction for about 1 month. Computed tomography and magnetic resonance imaging revealed diffuse wall thickening of the rectum, possible high cellularity in the lower portion of urinary bladder, and lesions in the visible pelvic bony structure. A colonoscopy showed a contiguous annular constriction from 5 to 15 cm above the anal verge. Carcinoembryonic antigen and carbohydrate antigen 19-9 levels were 39.75 ng/mL and 139.2 U/mL, respectively. A transurethral bladder biopsy revealed high-grade urothelial cell carcinoma, and anal biopsy showed a poorly differentiated carcinoma arranged in a small nested pattern within the subepithelial area of the anorectal tissue. A colostomy was performed, and the patient was transferred to another hospital for further treatment after series of survey with lung metastasis. Discussion Invasive bladder cancers rarely infiltrates into the rectum and is known with the difficulty diagnosis by colonoscopy. Furthermore, the secondary rectum tumor due to bladder cancer had poor record for survival in the literature review. Conclusion This case of bladder urothelial carcinoma penetrating to the rectum was interesting because it mimicked proctitis with diffuse annular swelling observed in the colonoscopy.

Rationale:Urethral hemangiomas commonly occur in men or elderly women. We presented a rare case of urethral hemangioma in a prepubertal female patient.Patients concerns:An 8-year-old girl had the complaints of bloody staining of clothing, a foul perineal odor, and urethral pain. She was brou

INTRODUCTION Emphysematous epididymo-orchitis is a rare cause of acute scrotum pain characterized by gas formation within the tissue. Diabetes mellitus and recto-seminal fistula secondary to sigmoid diverticulitis are generally accepted as being responsible for this disease. However, prostate invasion secondary to rectal cancer may be considered to be a newly identified pathogenetic mechanism. Herein, we report this rare case and illustrate the pathogenesis. CASE PRESENTATION A 69-year-old man arrived at our emergency department presenting with sepsis and acute scrotal pain. Emphysematous epididymo-orchitis was diagnosed by scrotal sonography initially; however, advanced rectal cancer with prostate invasion was diagnosed by CT after a recurrent episode. An exploratory laparotomy with abdominoperineal resection and radical prostectomy were performed after neoadjuvant chemoradiotherapy. Histopathologic analysis confirmed the previous diagnosis. Emphysematous epididymo-orchitis caused by advanced rectal cancer is very rare, and our case is the first to be reported according to a literature search. Neoadjuvant chemoradiotherapy plus extended surgery can achieve a good oncological outcome. CONCLUSION This case indicated that the very rare presentation as emphysematous epididymo-orchitis caused by locally advanced colorectal cancer.

A 53-year-old Taiwanese male had several episodes of left epididymitis with hydrocele refractory to antibiotic treatment. Partial epididymectomy plus preventive vasectomy were planned, and, incidentally, an ill-defined nodule was found lying on the tunica vaginalis near the epididymal head. The pathological diagnosis was malignant mesothelioma of the tunica vaginalis testis. Radical orchiectomy with wide excision of the hemi-scrotal wall was performed. So far, there is no evidence of recurrence after more than 3 years of follow-up. Malignant tumor should be considered in the case of recurrent epididymitis refractory to empirically effective antibiotic treatment. Although the nature of this tumor is highly fatal, the malignancy can possibly be cured by early and aggressive surgical treatment.
