A case of dermatofibrosarcoma protuberans of the scalp treated with surface mould brachytherapy.

Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive soft tissue tumor with a high propensity of local recurrence after surgery. Radiotherapy as an adjuvant therapy has been shown to reduce recurrent rates of this disease. Surface mould brachytherapy is an effective and safe modality for the delivery of radiotherapy in soft tissue tumors, though its utilization and popularity have decreased in recent years.

Impact of COVID-19 pandemic on older cancer patients: Proposed solution by the International Geriatric Radiotherapy Group.

Older cancer patients are disproportionally affected by the Coronavirus 19 (COVID-19) pandemic. A higher rate of death among the elderly and the potential for long-term disability have led to fear of contracting the virus in these patients. This fear can, paradoxically, cause delay in diagnosis and treatment that may lead to a poor outcome that could have been prevented.

Objective: To compare the effectiveness of treatment with autologous activated platelet-rich plasma (PRP), administered to either the subendometrium (SE-PRP) or endometrial surface (intrauterine; IU-PRP), against controls.

Design: Prospective observational cohort study.

Setting: Tertiary fertility unit.

Mitochondrial DNA Levels in Trophectodermal Cells Show No Association with Blastocyst Development and Pregnancy Outcomes.

Background: In patients undergoing assisted reproduction, levels of mitochondrial DNA (mtDNA) in the trophectodermal cells of the developing blastocyst are suggested to be associated with its ability to implant. However, discrepancies exist regarding the use of mtDNA levels as a reliable biomarker to predict outcomes of assisted reproduction.

Aims: The aim of the study is to explore the association of trophectodermal mtDNA levels to determine blastocyst quality, implantation potential of blastocyst and clinical outcomes in couples who have undergone pre-implantation genetic testing for aneuploidy (PGT-A).

Dehydroepiandrosterone (DHEA) role in enhancement and maintenance of implantation (DREAM): randomised double-blind placebo-controlled trial-study protocol.

Introduction: Dehydroepiandrosterone (DHEA) is an important precursor of androgen and has been studied and researched extensively for improving the various outcome measures of ovarian stimulation in women with advanced age or poor ovarian response. Androgens also play an important role in the enhancement of endometrial and decidual function by regulating both the transcriptome and secretome of the endometrial stromal cells and have a positive effect on various factors like insulin-like growth factor binding protein 1, homeobox genes (HOXA10, HOXA11), secreted phosphoprotein 1, prolactin which are necessary for implantation. It is well-known that the circulating 'precursor pool' of DHEA declines with age more so in poor ovarian reserve patients and exogenous supplementation may be beneficial in such cases.

Impact of Surface States and Aluminum Mole Fraction on Surface Potential and 2DEG in AlGaN/GaN HEMTs.

The presence of surface traps is an important phenomenon in AlGaN/GaN HEMT. The electrical and physical properties of these surface traps have been analyzed through the study of 2DEG electron concentration along with the variation of aluminum percentage in the barrier layer of HEMT. This analysis shows that from deep to shallow donors, the percentage change in electron density in 2DEG gets saturated (near 8%) with change in aluminum concentration.

Use of a Checklist Approach on a Telecobalt in an Attempt to Reduce Human Errors in Radiotherapy Delivery and Improve Therapeutic Ratio.

Background: The process of radiotherapy treatment planning and delivery involves multiple steps and professionals causing it to be prone to errors. Radiotherapy centers equipped with old telecobalt machines have certain peculiar challenges to workflow. We designed and tested a checklist for radiotherapy technicians (RTTs) to reduce chances of error during treatment delivery on a telecobalt machine.

Genuine Empty Follicle Syndrome: Role of Double Trigger and Delayed Oocyte Retrieval (DTDO).

Background: Empty follicle syndrome (EFS) is a condition of undetermined etiology where no oocytes are retrieved in an ART cycle despite adequate response to ovarian stimulation and diligent follicular aspiration. Because of the rarity of this condition, no much published strategies are available to tackle this.

Aim: The aim of this study was to evaluate whether sequential administration of gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG) as a trigger at 40 h and 36 h, respectively, before oocyte retrieval (OCR) could correct genuine empty follicle syndrome (GEFS).

Weight Loss as a Nutritional Indicator in Head and Neck Cancer Patients Undergoing Chemoradiotherapy: Contributing Factors and Its Impact on Disease Outcome.

This is a retrospective study carried out at a tertiary care cancer center to assess weight loss in patients of head and neck cancers (HNCs) during treatment with chemoradiotherapy (CRT) and study various factors affecting it. Treatment and follow-up records of 77 patients of HNCs were studied and assessed for demographic, disease-specific variables, treatment parameters, weight loss during CRT, as well as survival at 2 years after treatment completion. A statistical analysis was conducted to assess the association of study variables with weight loss.

Using positron-emission tomography-computed tomography for predicting radiotherapy-induced tumor regression in carcinoma esophagus in an Indian population.

Carcinoma esophagus is a common malignancy of the Indian subcontinent. The role of positron-emission tomography-computed tomography (PET-CT) in the assessment of response to radiotherapy has been widely studied and accepted. However, its precise use as a predictive tool for actual histopathological response to radiotherapy needs further evaluation, especially in an Indian population.

The Impact of Positron Emission Tomography/Computed Tomography Addition to Contrast-Enhanced Computed Tomography Findings during Radiation Treatment Planning of Locally Advanced Carcinoma Esophagus.

Introduction: Does metabolic imaging help in better definition of target during radiation treatment planning by bringing about changes in dimensions of the primary tumor in terms of diameter, length, and picking up new skip lesions or nodal stations which in turn prevents geographic misses by including more F-fluorodeoxyglucose avid regions not visible on conventional imaging?

Materials And Methods: We compared the length and radial dimensions of the primary tumor as well as changes brought about due to addition of new nodal stations, involved structures, and skip lesions in 50 patients of carcinoma esophagus treated between 2011 and 2013, as seen on contrast-enhanced computed tomography (CT) thorax and positron emission tomography (PET)/CT and drew conclusions regarding the technical changes brought about in treatment planning by the additional input of PET/CT.

Results And Conclusions: PET-CT tremendously changes treatment plans by expanding the gross tumor volume and including regions which might otherwise have been missed on purely CT-based plans. Of the 50 patients, it changed the contouring and treatment planning of 35 patients and did not impact the remaining 15.

Malignant peripheral nerve sheath tumor of thigh with sphenoid and brain metastases: Extremely rare occurrence with dismal prognosis despite significant response to palliative chemoradiotherapy.

Malignant peripheral nerve sheath tumor (MPNST) is a neurogenic tumor arising from peripheral nerves or nerve sheaths. MPNSTs are highly aggressive sarcomas mainly associated with neurofibromatosis type-1 (NF-1) with high rates of local recurrence and distant metastasis carrying a dismal prognosis. Lung is the most common metastatic site.

Radiation Fibrosis Syndrome: the Evergreen Menace of Radiation Therapy.

Fibrosis is a descriptive appellation referring to the obliteration of normal tissue components replaced by matrix and disorganized and varied collagen fibrils that result in the loss of organ function and frequent tissue contraction leading to death or significant deterioration in the quality of life. Radiation fibrosis syndrome (RFS) is a progressive fibrotic tissue sclerosis with various clinical symptoms in the irradiation field. It is usually a late complication of radiation therapy and may occur weeks or even years after treatment.

Upfront Skeletal Muscle Metastases from Non-small Cell Lung Carcinoma: Report of an Extremely Rare Occurrence Detected by 18F-Fluorodeoxyglucose Positron Emission Computed Tomography Scan.

Adenocarcinoma lung with upfront metastases to skeletal muscle is rarely encountered in clinical practice since skeletal muscles are highly resistant to dissemination from solid organs. Moreover, these muscle metastatic lesions generally present with pain and palpable mass to get detected clinically. However, silent skeletal muscle metastases without any symptoms or signs getting detected by functional imaging with whole body 18F-fluorodeoxyglucose positron emission/computed tomography (18FDG-PET/CT) scan have been scarcely described in literature, while we present such an interesting case in a 45-year-old female.

Micro-dissection testicular sperm extraction as an alternative for sperm acquisition in the most difficult cases of Azoospermia: Technique and preliminary results in India.

Context: Non-obstructive azoospermia (NOA) is an unfavorable prognostic condition for male infertility since spermatogenesis is disrupted. Sperm retrieval (SR) coupled with intracytoplasmic sperm injection (ICSI) is the only option for men with NOA who seek fertility. Among the SR techniques, microdissection testicular sperm extraction (micro-TESE) has been applied with encouraging results.
