Abstract:
Retrorectal cystic hamartomas (HCR) (“tailgut cyst” in English-language literature) are congenital cystic tumors derived from vestiges of the hindgut. Its incidence is low, being more frequent in adult women. They are variable in size, uni or multiloculated. They can be lined with several types of epithelia (squamous, transitional, mucinous,...) in a same cyst and can contain mucus. Lesions usually present during adulthood due to pain, discomfort, rectal bleeding, infection, or malignant transformation. The incidence of malignancy is low, being adenocarcinoma and neuroendocrine the most frequent tumors associated to HCR. We present a case of HCR associated with squamous cell carcinoma and discuss aspects of the treatment.

Abstract:
Solid tumor oncology treatments are primarily performed in the outpatient setting. However, hospitalizations are inevitable due to complications of cancer and treatment-related toxicities. With rising health care spending, the length of hospital stay (LOS) is increasingly considered a proxy for healthcare costs. There are several ongoing eff orts to abbreviate the inpatient LOS and ensure a safe and timely discharge to the outpatient setting. In addition to the acute illness and the associated comorbidities, various factors aff ect the LOS: social determinants of health (SDOH), nutritional status in cancer patients, and end-of-life issues. Furthermore, it is unclear how the institutional policies on social distancing and visitation during the current coronavirus disease (COVID-19) pandemic may impact the LOS. The purpose of this article is to review various factors and barriers that lead to longer LOS for solid tumor patients during the COVID-19 pandemic, and identify the critical areas of quality improvement.

Abstract:
Background: Leiomyoma itself is not a rare disease, but it is rarely found intravascularly. Case presentation: A 54-year old female sought medical help after noticing her leg being swelling. A diagnosis of deep vein thrombosis (DVT) was made and antithrombotic treatment was given after her initial imaging exam. Several days later, a contrast CT and sequential pathology revealed the real diagnosis was intravascular leiomyoma. The patient was discharged after a successful surgery. Conclusion: Intravascular leiomyoma should not be confused with DVT.

Abstract:
We evaluated a total of 115 patients diagnosed with anal cancer, who were treated at our clinic from 1995 to 2012. Their average age was 61 years, most often were diagnosed in stages II and III, in most cases it was a squamous cell carcinoma located in the anal canal. The mean follow-up was 83 months (minimum 1 month and maximum 240 months). We combined external radiotherapy with boost of brachytherapy or boost of external radiotherapy and possibly a combination of both boosts. Half of the patients received concomitant chemotherapy. We specifically evaluated local tumor regression, overall survival and the impact to therapeutic effect of the chosen irradiation technique. Complete regression was achieved in 92 patients, partial regression in 21 patients. Overall survival, regardless of stage, was 80% 3-year, 74% 5-year and 67% 10-year. The age of patients, the size of their own primary tumor and the therapeutic method used had a statistically significant effect on survival - especially the importance of brachytherapy was irreplaceable.

Abstract:
The RNA interference (RNAi) technique is a new modality for cancer therapy, and several candidates are being tested clinically. Nanotheranostics is a rapidly growing field combining disease diagnosis and therapy, which ultimately may add in the development of ‘personalized medicine’. Technologies on theranostic nanomedicines has been discussed. We designed and developed bioresponsive and fluorescent hyaluronic acid-iodixanol nanogels (HAI-NGs) for targeted X-ray computed tomography (CT) imaging and chemotherapy of MCF-7 human breast tumors. HAI-NGs were obtained with a small size of ca. 90 nm, bright green fluorescence and high serum stability from hyaluronic acid-cystamine-tetrazole and reductively degradable polyiodixanol-methacrylate via nanoprecipitation and a photo-click crosslinking reaction. This chapter presents an over view of the current status of translating the RNAi cancer therapeutics in the clinic, a brief description of the biological barriers in drug delivery, and the roles of imaging in aspects of administration route, systemic circulation, and cellular barriers for the clinical translation of RNAi cancer therapeutics, and with partial content for discussing the safety concerns. Finally, we focus on imaging-guided delivery of RNAi therapeutics in preclinical development, including the basic principles of different imaging modalities, and their advantages and limitations for biological imaging. With growing number of RNAi therapeutics entering the clinic, various imaging methods will play an important role in facilitating the translation of RNAi cancer therapeutics from bench to bedside.

Abstract:
Background: The aim of the study was to evaluate radiographic features of systemic sclerosis-associated interstitial lung disease. Patients and methods: 116 patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) from 2010 to 2019 comprised our retrospective study. All patients were subject to high resolution computed tomography (HRCT). ILD patterns were classified into 7 patterns as IIPs and analyzed with pathology. We chose two staging method and two semi-quantitative score methods to evaluate the HRCT performance and analyzed with pulmonary function tests. Results: Ground-glass opacities were the most common presentation on HRCT, followed by interlobular septal thickening, reticular opacities, intralobular interstitial thickening; honeycombing, traction bronchiectasis and nodules can also be observed. The most common pattern of SSc-ILD was nonspecific interstitial pneumonia (NSIP), secondly was UIP. There was no difference in ILD pattern between HRCT and pathology, and revealed a high congruence. The four HRCT evaluating methods presented in this study all had significant relationships with PETs. Conclusion: The most common pattern of SSc-ILD was nonspecific interstitial pneumonia (NSIP). The ILD patterns of HRCT coincide very well with histology, and will replace pathology as the gold standard for diagnosis and evaluation of SSc-ILD.

Abstract:
Background: Oral cancer accounts for 30% of all types of cancer in India. Surgery is the mainstay of treatment but due to the recent outbreak of COVID-19, there is a partial or complete disruption of health services in the country. The initial delay in the treatment was due to cancellations of planned surgeries as per government regulations and reduction in public transportation. In the latter half of the initial relaxation of the lockdown, we formulated our institutional protocol for the surgical treatment of oral cancer patients. On admission, all patients were kept in isolated wards followed by RT-PCR (Reverse Transcriptase-Polymerase Chain Reaction) testing on the same day. RT-PCR negative patients are subjected to HRCT Thorax (High-resolution Computer Tomography). This ensured the safety of health care workers, patients, and patient attendees. Keeping this in mind, we did an observational study on the role of HRCT in the pre-operative screening of asymptomatic oral cancer patients. Materials and methods: Retrospective analysis of prospectively collected data of 150 patients was done. HRCT reporting was done by two experienced senior radiologists of the Department of Radiology at our hospital. Results: The number of patients under the CO-RADS 1 category was 121 and CO-RADS 2 category was 29, according to CO-RADS classification. The results of RT-PCR and HRCT were compared and there was a 100% positive correlation between RT-PCR and HRCT Thorax. Conclusion: Our study supported the use of HRCT Thorax as a diagnostic tool in pre-operative screening of oral cancer patients for COVID 19, particularly in RT-PCR negative cases.
